How to handle XML string %Like% search in C#

- by Nano HE

Hi, As I know I can search DB with Sql %like% syntax. Now I am working with XML, how can I handle the same search condition for XML file in C#? Thank you.

The command redirect_to "http://google.com" doesn't appear to be working!

So I have the final line in my controller: redirect_to "http://google.com" And the prod log has: Redirected to http://google.com Completed in 8ms (DB: 4) | 302 Found [http://www.exmaple.com/728zz5d/delete_stuff] And the web page still had the original info - I'm not sent to google??? What am I not understanding?

NuGet package manager in Visual Studio 2012

- by sreejukg

NuGet is a package manager that helps developers to automate the process of installing and upgrading packages in Visual Studio projects. It is free and open source. You can see the project in codeplex from the below link. http://nuget.codeplex.com/ Now days developers needed to work with several packages or libraries from various sources, a typical e.g. is jQuery. You will hardly find a website that not uses jQuery. When you include these packages as manually copying the files, it is difficult to task to update these files as new versions get released. NuGet is a Visual studio add on, that comes by default with Visual Studio 2012 that manages such packages. So by using NuGet, you can include new packages to you project as well as update existing ones with the latest versions. NuGet is a Visual Studio extension, and happy news for developers, it is shipped with Visual Studio 2012 by default. In this article, I am going to demonstrate how you can include jQuery (or anything similar) to a .Net project using the NuGet package manager. I have Visual Studio 2012, and I created an empty ASP.Net web application. In the solution explorer, the project looks like following. Now I need to add jQuery for this project, for this I am going to use NuGet. From solution explorer, right click the project, you will see “Manage NuGet Packages” Click on the Manage NuGet Packages options so that you will get the NuGet Package manager dialog. Since there is no package installed in my project, you will see “no packages installed” message. From the left menu, select the online option, and in the Search box (that is available in the top right corner) enter the name of the package you are looking for. In my case I just entered jQuery. Now NuGet package manager will search online and bring all the available packages that match my search criteria. You can select the right package and use the Install button just next to the package details. Also in the right pane, it will show the link to project information and license terms, you can see more details of the project you are looking for from the provided links. Now I have selected to install jQuery. Once installed successfully, you can find the green icon next to it that tells you the package has been installed successfully to your project. Now if you go to the Installed packages link from the left menu of package manager, you can see jQuery is installed and you can uninstall it by just clicking on the Uninstall button. Now close the package manager dialog and let us examine the project in solution explorer. You can see some new entries in your project. One is Scripts folder where the jQuery got installed, and a packages.config file. The packages.config is xml file that tells the NuGet package manager, the id and the version of the package you install. Based on this file NuGet package manager will identify the installed packages and the corresponding versions. Installing packages using NuGet package manager will save lot of time for developers and developers can get upgrades for the installed packages very easily.

SQL SERVER – Update Statistics are Sampled By Default

- by pinaldave

After reading my earlier post SQL SERVER – Create Primary Key with Specific Name when Creating Table on Statistics, I have received another question by a blog reader. The question is as follows: Question: Are the statistics sampled by default? Answer: Yes. The sampling rate can be specified by the user and it can be anywhere between a very low value to 100%. Let us do a small experiment to verify if the auto update on statistics is left on. Also, let’s examine a very large table that is created and statistics by default- whether the statistics are sampled or not. USE [AdventureWorks] GO -- Create Table CREATE TABLE [dbo].[StatsTest]( [ID] [int] IDENTITY(1,1) NOT NULL, [FirstName] [varchar](100) NULL, [LastName] [varchar](100) NULL, [City] [varchar](100) NULL, CONSTRAINT [PK_StatsTest] PRIMARY KEY CLUSTERED ([ID] ASC) ) ON [PRIMARY] GO -- Insert 1 Million Rows INSERT INTO [dbo].[StatsTest] (FirstName,LastName,City) SELECT TOP 1000000 'Bob', CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%2 = 1 THEN 'Smith' ELSE 'Brown' END, CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%10 = 1 THEN 'New York' WHEN ROW_NUMBER() OVER (ORDER BY a.name)%10 = 5 THEN 'San Marino' WHEN ROW_NUMBER() OVER (ORDER BY a.name)%10 = 3 THEN 'Los Angeles' ELSE 'Houston' END FROM sys.all_objects a CROSS JOIN sys.all_objects b GO -- Update the statistics UPDATE STATISTICS [dbo].[StatsTest] GO -- Shows the statistics DBCC SHOW_STATISTICS ("StatsTest"PK_StatsTest) GO -- Clean up DROP TABLE [dbo].[StatsTest] GO Now let us observe the result of the DBCC SHOW_STATISTICS. The result shows that Resultset is for sure sampling for a large dataset. The percentage of sampling is based on data distribution as well as the kind of data in the table. Before dropping the table, let us check first the size of the table. The size of the table is 35 MB. Now, let us run the above code with lesser number of the rows. USE [AdventureWorks] GO -- Create Table CREATE TABLE [dbo].[StatsTest]( [ID] [int] IDENTITY(1,1) NOT NULL, [FirstName] [varchar](100) NULL, [LastName] [varchar](100) NULL, [City] [varchar](100) NULL, CONSTRAINT [PK_StatsTest] PRIMARY KEY CLUSTERED ([ID] ASC) ) ON [PRIMARY] GO -- Insert 1 Hundred Thousand Rows INSERT INTO [dbo].[StatsTest] (FirstName,LastName,City) SELECT TOP 100000 'Bob', CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%2 = 1 THEN 'Smith' ELSE 'Brown' END, CASE WHEN ROW_NUMBER() OVER (ORDER BY a.name)%10 = 1 THEN 'New York' WHEN ROW_NUMBER() OVER (ORDER BY a.name)%10 = 5 THEN 'San Marino' WHEN ROW_NUMBER() OVER (ORDER BY a.name)%10 = 3 THEN 'Los Angeles' ELSE 'Houston' END FROM sys.all_objects a CROSS JOIN sys.all_objects b GO -- Update the statistics UPDATE STATISTICS [dbo].[StatsTest] GO -- Shows the statistics DBCC SHOW_STATISTICS ("StatsTest"PK_StatsTest) GO -- Clean up DROP TABLE [dbo].[StatsTest] GO You can see that Rows Sampled is just the same as Rows of the table. In this case, the sample rate is 100%. Before dropping the table, let us also check the size of the table. The size of the table is less than 4 MB. Let us compare the Result set just for a valid reference. Test 1: Total Rows: 1000000, Rows Sampled: 255420, Size of the Table: 35.516 MB Test 2: Total Rows: 100000, Rows Sampled: 100000, Size of the Table: 3.555 MB The reason behind the sample in the Test1 is that the data space is larger than 8 MB, and therefore it uses more than 1024 data pages. If the data space is smaller than 8 MB and uses less than 1024 data pages, then the sampling does not happen. Sampling aids in reducing excessive data scan; however, sometimes it reduces the accuracy of the data as well. Please note that this is just a sample test and there is no way it can be claimed as a benchmark test. The result can be dissimilar on different machines. There are lots of other information can be included when talking about this subject. I will write detail post covering all the subject very soon.

How to implement multi-source XSLT mapping in 11g BPEL

- by [email protected]

In SOA 11g, you can create a XSLT mapper that uses multiple sources as the input. To implement a multi-source mapper, just follow the instructions below, Drag and drop a Transform Activity to a BPEL process Double-click on the Transform Activity, the Transform dialog window appears. Add source variables by clicking the Add icon and selecting the variable and part of the variable as needed. You can select multiple input variables. The first variable represents the main XML input to the XSL mapping, while additional variables that are added here are defined in the XSL mapping as input parameters. Select the target variable and its part if available. Specify the mapper file name, the default file name is xsl/Transformation_%SEQ%.xsl, where %SEQ% represents the sequence number of the mapper. Click OK, the xls file will be opened in the graphical mode. You can map the sources to the target as usual. Open the mapper source code, you will notice the variable representing the additional source payload, is defined as the input parameter in the map source spec and body<mapSources> <source type="XSD"> <schema location="../xsd/po.xsd"/> <rootElement name="PurchaseOrder" namespace="http://www.oracle.com/pcbpel/po"/> </source> <source type="XSD"> <schema location="../xsd/customer.xsd"/> <rootElement name="Customer" namespace="http://www.oracle.com/pcbpel/Customer"/> <param name="v_customer" /> </source> </mapSources>...<xsl:param name="v_customer"/> Let's take a look at the BPEL source code used to execute xslt mapper. <assign name="Transform_1"> <bpelx:annotation> <bpelx:pattern>transformation</bpelx:pattern> </bpelx:annotation> <copy> <from expression="ora:doXSLTransformForDoc('xsl/Transformation_1.xsl',bpws:getVariableData('v_po'),'v_customer',bpws:getVariableData('v_customer'))"/> <to variable="v_invoice"/> </copy> </assign> You will see BPEL uses ora:doXSLTransformForDoc XPath function to execute the XSLT mapper.This function returns the result of XSLT transformation when the xslt template matching the document. The signature of this function is ora:doXSLTransformForDoc(template,input, [paramQName, paramValue]*).Wheretemplate is the XSLT mapper nameinput is the string representation of xml input, paramQName is the parameter defined in the xslt mapper as the additional sourceparameterValue is the additional source payload. You can add more sources to the mapper at the later stage, but you have to modify the ora:doXSLTransformForDoc in the BPEL source code and make sure it passes correct parameter and its value pair that reflects the changes in the XSLT mapper.So the best practices are : create the variables before creating the mapping file, therefore you can add multiple sources when you define the transformation in the first place, which is more straightforward than adding them later on. Review ora:doXSLTransformForDoc code in the BPEL source and make sure it passes the correct parameters to the mapper.

SQL SERVER – Introduction to Wait Stats and Wait Types – Wait Type – Day 1 of 28

- by pinaldave

I have been working a lot on Wait Stats and Wait Types recently. Last Year, I requested blog readers to send me their respective server’s wait stats. I appreciate their kind response as I have received Wait stats from my readers. I took each of the results and carefully analyzed them. I provided necessary feedback to the person who sent me his wait stats and wait types. Based on the feedbacks I got, many of the readers have tuned their server. After a while I got further feedbacks on my recommendations and again, I collected wait stats. I recorded the wait stats and my recommendations and did further research. At some point at time, there were more than 10 different round trips of the recommendations and suggestions. Finally, after six month of working my hands on performance tuning, I have collected some real world wisdom because of this. Now I plan to share my findings with all of you over here. Before anything else, please note that all of these are based on my personal observations and opinions. They may or may not match the theory available at other places. Some of the suggestions may not match your situation. Remember, every server is different and consequently, there is more than one solution to a particular problem. However, this series is written with kept wait stats in mind. While I was working on various performance tuning consultations, I did many more things than just tuning wait stats. Today we will discuss how to capture the wait stats. I use the script diagnostic script created by my friend and SQL Server Expert Glenn Berry to collect wait stats. Here is the script to collect the wait stats: -- Isolate top waits for server instance since last restart or statistics clear WITH Waits AS (SELECT wait_type, wait_time_ms / 1000. AS wait_time_s, 100. * wait_time_ms / SUM(wait_time_ms) OVER() AS pct, ROW_NUMBER() OVER(ORDER BY wait_time_ms DESC) AS rn FROM sys.dm_os_wait_stats WHERE wait_type NOT IN ('CLR_SEMAPHORE','LAZYWRITER_SLEEP','RESOURCE_QUEUE','SLEEP_TASK' ,'SLEEP_SYSTEMTASK','SQLTRACE_BUFFER_FLUSH','WAITFOR', 'LOGMGR_QUEUE','CHECKPOINT_QUEUE' ,'REQUEST_FOR_DEADLOCK_SEARCH','XE_TIMER_EVENT','BROKER_TO_FLUSH','BROKER_TASK_STOP','CLR_MANUAL_EVENT' ,'CLR_AUTO_EVENT','DISPATCHER_QUEUE_SEMAPHORE', 'FT_IFTS_SCHEDULER_IDLE_WAIT' ,'XE_DISPATCHER_WAIT', 'XE_DISPATCHER_JOIN', 'SQLTRACE_INCREMENTAL_FLUSH_SLEEP')) SELECT W1.wait_type, CAST(W1.wait_time_s AS DECIMAL(12, 2)) AS wait_time_s, CAST(W1.pct AS DECIMAL(12, 2)) AS pct, CAST(SUM(W2.pct) AS DECIMAL(12, 2)) AS running_pct FROM Waits AS W1 INNER JOIN Waits AS W2 ON W2.rn <= W1.rn GROUP BY W1.rn, W1.wait_type, W1.wait_time_s, W1.pct HAVING SUM(W2.pct) - W1.pct < 99 OPTION (RECOMPILE); -- percentage threshold GO This script uses Dynamic Management View sys.dm_os_wait_stats to collect the wait stats. It omits the system-related wait stats which are not useful to diagnose performance-related bottleneck. Additionally, not OPTION (RECOMPILE) at the end of the DMV will ensure that every time the query runs, it retrieves new data and not the cached data. This dynamic management view collects all the information since the time when the SQL Server services have been restarted. You can also manually clear the wait stats using the following command: DBCC SQLPERF('sys.dm_os_wait_stats', CLEAR); Once the wait stats are collected, we can start analysis them and try to see what is causing any particular wait stats to achieve higher percentages than the others. Many waits stats are related to one another. When the CPU pressure is high, all the CPU-related wait stats show up on top. But when that is fixed, all the wait stats related to the CPU start showing reasonable percentages. It is difficult to have a sure solution, but there are good indications and good suggestions on how to solve this. I will keep this blog post updated as I will post more details about wait stats and how I reduce them. The reference to Book On Line is over here. Of course, I have selected February to run this Wait Stats series. I am already cheating by having the smallest month to run this series. :) Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: DMV, Pinal Dave, PostADay, SQL, SQL Authority, SQL Optimization, SQL Performance, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, SQL Wait Stats, SQL Wait Types, T SQL, Technology

Add New Features to WMP with Windows Media Player Plus

- by DigitalGeekery

Do you use Windows Media Player 11 or 12 as your default media player? Today, we’re going to show you how to add some handy new features and enhancements with the Windows Media Player Plus third party plug-in. Installation and Setup Download and install Media Player Plus! (link below). You’ll need to close out of Windows Media Player before you begin or you’ll receive the message below. The next time you open Media Player you’ll be presented with the Media Player Plus settings window. Some of the settings will be enabled by default, such as the Find as you type feature. Using Media Player Plus! Find as you type allows you to start typing a search term from anywhere in Media Player without having to be in the Search box. The search term will automatically fill in the search box and display the results. You’ll also see Disable group headers in the Library Pane. This setting will display library items in a continuous list similar to the functionality of Windows Media Player 10. Under User Interface you can enable displaying the currently playing artist and title in the title bar. This is enabled by default. The Context Menu page allows you to enable context menu enhancements. The File menu enhancement allows you to add the Windows Context menu to Media Player on the library pane, list pane, or both. Right click on a Title, select File, and you’ll see the Windows Context Menu. Right-click on a title and select Tag Editor Plus. Tag Editor Plus allows you to quickly edit media tags. The Advanced tab displays a number of tags that Media Player usually doesn’t show. Only the tags with the notepad and pencil icon are editable. The Restore Plug-ins page allows you to configure which plug-ins should be automatically restored after a Media Player crash. The Restore Media at Startup page allows you to configure Media Player to resume playing the last playlist, track, and even whether it was playing or paused at the time the application was closed. So, if you close out in the middle of a song, it will begin playing from that point the next time you open Media Player. You can also set Media Player to rewind a certain number of seconds from where you left off. This is especially useful if you are in the middle of watching a movie. There’s also the option to have your currently playing song sent to Windows Live Messenger. You can access the settings at any time by going to Tools, Plug-in properties, and selecting Windows Media Player Plus. Windows Media Plus is a nice little free plug-in for WMP 11 and 12 that brings a lot of additional functionality to Windows Media Player. If you use Media Player 11 or WMP 12 in Windows 7 as your main player, you might want to give this a try. Download Windows Media Player Plus!

How To Disable Control Panel in Windows 7

- by Mysticgeek

If you have a shared computer that your family and friends can access, you might not want them to mess around in the Control Panel, and luckily with a simple tweak you can disable it. Disable Control Panel with Group Policy Note: This process uses Local Group Policy Editor which is not available in Home versions of Windows 7. Skip down below for the registry hack version that works on Home editions as well. First type gpedit.msc into the Search box in the Start menu and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select Control Panel in the left Column. In the right column double-click on Prohibit access to the Control Panel. In the next window, select Enable, click OK, then close out of Local Group Policy Editor. After the Control Panel is disabled, you’ll notice it’s no longer listed in the Start Menu. If the user tries to type Control Panel into the Search box in the Start menu, they will get the following message indicating it’s restricted. Disable Control Panel with a Registry Tweak You can also tweak the Registry to disable Control Panel. This will work with all versions of Windows 7, Vista, and XP. Making changes in the Registry is not recommended for beginners and you should create a Restore Point, or backup the Registry before making any changes. Type regedit into the Search box in the Start menu and hit Enter. In Registry Editor navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer. Then right-click in the right pane and create a new DWORD (32-bit) Value. Name the value NoControlPanel. Then right-click on the new Value and click Modify… In the Value data field change the value to “1” then click OK. Close out of Registry Editor and restart the machine to complete the process. When you get back from reboot, you’ll notice Control Panel is no longer listed in the Start menu. If a user tries to access it by typing Control Panel into the Search box in the Start menu… They will get the following message indicating it is restricted, just like if you were to disable it via Group Policy. If you want to re-enable the Control Panel, go back into the Registry and change the NoControlPanel value back to “0” then reboot the computer. This comes in handy if you have inexperienced users working on your machine and don’t want them messing with Control Panel settings.

Programação paralela no .NET Framework 4 – Parte II

- by anobre

Olá pessoal, tudo bem? Este post é uma continuação da série iniciada neste outro post, sobre programação paralela. Meu objetivo hoje é apresentar o PLINQ, algo que poderá ser utilizado imediatamente nos projetos de vocês. Parallel LINQ (PLINQ) PLINQ nada mais é que uma implementação de programação paralela ao nosso famoso LINQ, através de métodos de extensão. O LINQ foi lançado com a versão 3.0 na plataforma .NET, apresentando uma maneira muito mais fácil e segura de manipular coleções IEnumerable ou IEnumerable<T>. O que veremos hoje é a “alteração” do LINQ to Objects, que é direcionado a coleções de objetos em memória. A principal diferença entre o LINQ to Objects “normal” e o paralelo é que na segunda opção o processamento é realizado tentando utilizar todos os recursos disponíveis para tal, obtendo uma melhora significante de performance. CUIDADO: Nem todas as operações ficam mais rápidas utilizando recursos de paralelismo. Não deixe de ler a seção “Performance” abaixo. ParallelEnumerable Tudo que a gente precisa para este post está organizado na classe ParallelEnumerable. Esta classe contém os métodos que iremos utilizar neste post, e muito mais: AsParallel AsSequential AsOrdered AsUnordered WithCancellation WithDegreeOfParallelism WithMergeOptions WithExecutionMode ForAll … O exemplo mais básico de como executar um código PLINQ é utilizando o métodos AsParallel, como o exemplo: var source = Enumerable.Range(1, 10000); var evenNums = from num in source.AsParallel() where Compute(num) > 0 select num; Algo tão interessante quanto esta facilidade é que o PLINQ não executa sempre de forma paralela. Dependendo da situação e da análise de alguns itens no cenário de execução, talvez seja mais adequado executar o código de forma sequencial – e nativamente o próprio PLINQ faz esta escolha. É possível forçar a execução para sempre utilizar o paralelismo, caso seja necessário. Utilize o método WithExecutionMode no seu código PLINQ. Um teste muito simples onde podemos visualizar a diferença é demonstrado abaixo: static void Main(string[] args) { IEnumerable<int> numbers = Enumerable.Range(1, 1000); IEnumerable<int> results = from n in numbers.AsParallel() where IsDivisibleByFive(n) select n; Stopwatch sw = Stopwatch.StartNew(); IList<int> resultsList = results.ToList(); Console.WriteLine("{0} itens", resultsList.Count()); sw.Stop(); Console.WriteLine("Tempo de execução: {0} ms", sw.ElapsedMilliseconds); Console.WriteLine("Fim..."); Console.ReadKey(true); } static bool IsDivisibleByFive(int i) { Thread.SpinWait(2000000); return i % 5 == 0; } Basta remover o AsParallel da instrução LINQ que você terá uma noção prática da diferença de performance. 1. Instrução utilizando AsParallel 2. Instrução sem utilizar paralelismo Performance Apesar de todos os benefícios, não podemos utilizar PLINQ sem conhecer todos os seus detalhes. Lembre-se de fazer as perguntas básicas: Eu tenho trabalho suficiente que justifique utilizar paralelismo? Mesmo com o overhead do PLINQ, vamos ter algum benefício? Por este motivo, visite este link e conheça todos os aspectos, antes de utilizar os recursos disponíveis. Conclusão Utilizar recursos de paralelismo é ótimo, aumenta a performance, utiliza o investimento realizado em hardware – tudo isso sem custo de produtividade. Porém, não podemos usufruir de qualquer tipo de tecnologia sem conhece-la a fundo antes. Portanto, faça bom uso, mas não esqueça de manter o conhecimento a frente da empolgação. Abraços.

Boot From a USB Drive Even if your BIOS Won’t Let You

- by Trevor Bekolay

You’ve always got a trusty bootable USB flash drive with you to solve computer problems, but what if a PC’s BIOS won’t let you boot from USB? We’ll show you how to make a CD or floppy disk that will let you boot from your USB drive. This boot menu, like many created before USB drives became cheap and commonplace, does not include an option to boot from a USB drive. A piece of freeware called PLoP Boot Manager solves this problem, offering an image that can burned to a CD or put on a floppy disk, and enables you to boot to a variety of devices, including USB drives. Put PLoP on a CD PLoP comes as a zip file, which includes a variety of files. To put PLoP on a CD, you will need either plpbt.iso or plpbtnoemul.iso from that zip file. Either disc image should work on most computers, though if in doubt plpbtnoemul.iso should work “everywhere,” according to the readme included with PLoP Boot Manager. Burn plpbtnoemul.iso or plpbt.iso to a CD and then skip to the “booting PLoP Boot Manager” section. Put PLoP on a Floppy Disk If your computer is old enough to still have a floppy drive, then you will need to put the contents of the plpbt.img image file found in PLoP’s zip file on a floppy disk. To do this, we’ll use a freeware utility called RawWrite for Windows. We aren’t fortunate enough to have a floppy drive installed, but if you do it should be listed in the Floppy drive drop-down box. Select your floppy drive, then click on the “…” button and browse to plpbt.img. Press the Write button to write PLoP boot manager to your floppy disk. Booting PLoP Boot Manager To boot PLoP, you will need to have your CD or floppy drive boot with higher precedence than your hard drive. In many cases, especially with floppy disks, this is done by default. If the CD or floppy drive is not set to boot first, then you will need to access your BIOS’s boot menu, or the setup menu. The exact steps to do this vary depending on your BIOS – to get a detailed description of the process, search for your motherboard’s manual (or your laptop’s manual if you’re working with a laptop). In general, however, as the computer boots up, some important keyboard strokes are noted somewhere prominent on the screen. In our case, they are at the bottom of the screen. Press Escape to bring up the Boot Menu. Previously, we burned a CD with PLoP Boot Manager on it, so we will select the CD-ROM Drive option and hit Enter. If your BIOS does not have a Boot Menu, then you will need to access the Setup menu and change the boot order to give the floppy disk or CD-ROM Drive higher precedence than the hard drive. Usually this setting is found in the “Boot” or “Advanced” section of the Setup menu. If done correctly, PLoP Boot Manager will load up, giving a number of boot options. Highlight USB and press Enter. PLoP begins loading from the USB drive. Despite our BIOS not having the option, we’re now booting using the USB drive, which in our case holds an Ubuntu Live CD! This is a pretty geeky way to get your PC to boot from a USB…provided your computer still has a floppy drive. Of course if your BIOS won’t boot from a USB it probably has one…or you really need to update it.

PHP PSR-0 + several namespaces in one file and autoload

- by Nemoden

I've been thinking for a while about defining several namespaces in one php file and so, having several classes inside this file. Suppose, I want to implement something like Doctrine\ORM\Query\Expr: Expr.php Expr |-- Andx.php |-- Base.php |-- Comparison.php |-- Composite.php |-- From.php |-- Func.php |-- GroupBy.php |-- Join.php |-- Literal.php |-- Math.php |-- OrderBy.php |-- Orx.php `-- Select.php It would be nice if I had all of this in one file - Expr.php: namespace Doctrine\ORM\Query; class Expr { // code } namespace Doctrine\ORM\Query\Expr; class Func { // code } // etc... What I'm thinking of is directories naming convention and, unlike PSR-0 having several classes and namespaces in one file. It's best explained by the code: ls Doctrine/orm/query Expr.php that's it - only Expr.php Since Expr.php is somewhat I call a "meta-namespace" for Expr\Func, it make sense to place all the classes inside Expr.php (as shown above). So, the vendor name is still starts with an uppercased letter (Doctrine) and the other parts of namespace start with lowercased letter. We can write an autoload so it would respect this notion: function load_class($class) { if (class_exists($class)) { return true; } $tokenized_path = explode(array("_", "\\"), DIRECTORY_SEPARATOR, $class); // array('Doctrine', 'orm', 'query', 'Expr', 'Func'); // ^^^^ // first, we are looking for first uppercased namespace part // and if it's not last (not the class name), we use it as a filename // and wiping away the rest to compose a path to a file we need to include if (FALSE !== ($meta_class_index = find_meta_class($tokenized_path))) { $new_tokenized_path = array_slice($tokenized_path, 0, $meta_class_index); $path_to_class = implode(DIRECTORY_SEPARATOR, $new_tokenized_path); } else { // no meta class found $path_to_class = implode(DIRECTORY_SEPARATOR, $tokenized_path); } if (file_exists($path_to_class.'.php')) { require_once $path_to_class.'.php'; } return false; } Another reason to do so is to reduce a number of php files scattered among directories. Usually you check file existence before you require a file to fail gracefully: file_exists($path_to_class.'.php'); If you take a look at actual Doctrine\ORM\Query\Expr code, you'll see they use all of the "inner-classes", so you actually do: file_exists("/path/to/Doctrine/ORM/Query/Expr.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/AndX.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Base.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Comparison.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Composite.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/From.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Func.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/GroupBy.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Join.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Literal.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Math.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/OrderBy.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Orx.php"); file_exists("/path/to/Doctrine/ORM/Query/Expr/Select.php"); in your autoload which causes quite a few I/O reads. Isn't it too much to check on each user's hit? I'm just putting this on a discussion. I want to hear from another PHP programmers what do they think of it. And, of course, if you have a silver bullet addressing this problems I've designated here, please share. I also have been thinking if my vogue question fits here and according to the FAQ it seems like this question addresses "software architecture" problem slash proposal. I'm sorry if my scribble may seem a bit clunky :) Thanks.

SQL SERVER – Auto Complete and Format T-SQL Code – Devart SQL Complete

- by pinaldave

Some people call it laziness, some will call it efficiency, some think it is the right thing to do. At any rate, tools are meant to make a job easier, and I like to use various tools. If we consider the history of the world, if we all wanted to keep traditional practices, we would have never invented the wheel. But as time progressed, people wanted convenience and efficiency, which then led to laziness. Wanting a more efficient way to do something is not inherently lazy. That’s how I see any efficiency tools. A few days ago I found Devart SQL Complete. It took less than a minute to install, and after installation it just worked without needing any tweaking. Once I started using it I was impressed with how fast it formats SQL code – you can write down any terms or even copy and paste. You can start typing right away, and it will complete keywords, object names, and fragmentations. It completes statement expressions. How many times do we write insert, update, delete? Take this example: to alter a stored procedure name, we don’t remember the code written in it, you have to write it over again, or go back to SQL Server Studio Manager to create and alter which is very difficult. With SQL Complete , you can write “alter stored procedure,” and it will finish it for you, and you can modify as needed. I love to write code, and I love well-written code. When I am working with clients, and I find people whose code have not been written properly, I feel a little uncomfortable. It is difficult to deal with code that is in the wrong case, with no line breaks, no white spaces, improper indents, and no text wrapping. The worst thing to encounter is code that goes all the way to the right side, and you have to scroll a million times because there are no breaks or indents. SQL Complete will take care of this for you – if a developer is too lazy for proper formatting, then Devart’s SQL formatter tool will make them better, not lazier. SQL Management Studio gives information about your code when you hover your mouse over it, however SQL Complete goes further in it, going into the work table, and the current rate idea, too. It gives you more information about the parameters; and last but not least, it will just take you to the help file of code navigation. It will open object explorer in a document viewer. You can start going through the various properties of your code – a very important thing to do. Here are are interesting Intellisense examples: 1) We are often very lazy to expand *however, when we are using SQL Complete we can just mouse over the * and it will give us all the the column names and we can select the appropriate columns. 2) We can put the cursor after * and it will give us option to expand it to all the column names by pressing the Tab key. 3) Here is one more Intellisense feature I really liked it. I always alias my tables and I always select the alias with special logic. When I was using SQL Complete I selected just a tablename (without schema name) and…(just like below image) … and it autocompleted the schema and alias name (the way I needed it). I believe using SQL Complete we can work faster. It supports all versions of SQL Server, and works SQL formatting. Many businesses perform code review and have code standards, so why not use an efficiency tool on everyone’s computer and make sure the code is written correctly from the first time? If you’re interested in this tool, there are free editions available. If you like it, you can buy it. I bought it because it works. I love it, and I want to hear all your opinions on it, too. You can get the product for FREE.

How to configure Visual Studio 2010 code coverage for ASP.NET MVC unit tests

- by DigiMortal

I just got Visual Studio 2010 code coverage work with ASP.NET MVC application unit tests. Everything is simple after you have spent some time with forums, blogs and Google. To save your valuable time I wrote this posting to guide you through the process of making code coverage work with ASP.NET MVC application unit tests. After some fighting with Visual Studio I got everything to work as expected. I am still not very sure why users must deal with this mess, but okay – I survived it. Before you start configuring Visual Studio I expect your solution meets the following needs: there are at least one library that will be tested, there is at least on library that contains tests to be run, there are some classes and some tests for them, and, of course, you are using version of Visual Studio 2010 that supports tests (I have Visual Studio 2010 Ultimate). Now open the following screenshot to separate windows and follow the steps given below. Visual Studio 2010 Test Settings window. Click on image to see it at original size. Double click on Local.testsettings under Solution Items. Test settings window will be opened. Select “Data and Diagnostics” from left pane. Mark checkboxes “ASP.NET Profiler” and “Code Coverage”. Move cursor to “Code Coverage” line and press Configure button or make double click on line. Assemblies selection window will be opened. Mark checkboxes that are located before assemblies about what you want code coverage reports and apply settings. Save your project and close Visual Studio. Run Visual Studio as Administrator and run tests. NB! Select Test => Run => Tests in Current Context from menu. When tests are run you can open code coverage results by selecting Test => Windows => Code Coverage Results from menu. Here you can see my example test results. Visual Studio 2010 Test Results window. All my tests passed this time. :) Click on image to see it at original size. And here are the code coverage results. Visual Studio 2101 Code Coverage Results. I need a lot more tests for sure. Click on image to see it at original size. As you can see everything was pretty simple. But it took me sometime to figure out how to get everything work as expected. Problems? You may face some problems when making code coverage work. Here is my short list of possible problems. Make sure you have all assemblies available for code coverage. In some cases it needs more libraries to be referenced as you currently have. By example, I had to add some more Enterprise Library assemblies to my project. You can use EventViewer to discover errors that where given during testing. Make sure you selected all testable assemblies from Code Coverage settings like shown above. Otherwise you may get empty results. Tests with code coverage are slower because we need ASP.NET profiler. If your machine slows down then try to free more resources.

Creating PDF documents dynamically using Umbraco and XSL-FO part 2

- by Vizioz Limited

Since my last post I have made a few modifications to the PDF generation, the main one being that the files are now dynamically renamed so that they reflect the name of the case study instead of all being called PDF.PDF which was not a very helpful filename, I just wanted to get something live last week, so decided that something was better than nothing :)The issue with the filenames comes down to the way that the PDF's are being generated by using an alternative template in Umbraco, this means that all you need to do is add " /pdf " to the end of a case study URL and it will create a PDF version of the case study. The down side is that your browser will merrily download the file and save it as PDF.PDF because that is the name of the last part of the URL.What you need to do is set the content-disposition header to be equal to the name you would like the file use, Darren Ferguson mentioned this on the Change the name of the PDF forum post.We have used the same technique for downloading dynamically generated excel files, so I thought it would be useful to create a small macro to set both this header and also to set the caching headers to prevent any caching issues, I think in the past we have experienced all possible issues, including various issues where IE behaves differently to other browsers when you are using SSL and so the below code should work in all situations!The template for the PDF alternative template is very simple:<%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %><asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolderDefault" runat="server"> <umbraco:Macro Alias="PDFHeaders" runat="server"></umbraco:Macro> <umbraco:Macro xsl="FO-CaseStudy.xslt" Alias="PDFXSLFO" runat="server"></umbraco:Macro></asp:Content>The following code snippet is the XSLT macro that simply creates our file name and then passes the file name into the helper function:<xsl:template match="/"> <xsl:variable name="fileName"> <xsl:text>Vizioz_</xsl:text> <xsl:value-of select="$currentPage/@nodeName" /> <xsl:text>_case_study.pdf</xsl:text> </xsl:variable> <xsl:value-of select="Vizioz.Helper:AddDocumentDownloadHeaders('application/pdf', $fileName)"/> </xsl:template>And the following code is the helper function that clears the current response and adds all the appropriate headers:public static void AddDocumentDownloadHeaders(string contentType, string fileName){ HttpResponse response = HttpContext.Current.Response; HttpRequest request = HttpContext.Current.Request; response.Clear(); response.ClearHeaders(); if (request.IsSecureConnection & request.Browser.Browser == "IE") { // Don't use the caching headers if the browser is IE and it's a secure connection // see: http://support.microsoft.com/kb/323308 } else { // force not using the cache response.AppendHeader("Cache-Control", "no-cache"); response.AppendHeader("Cache-Control", "private"); response.AppendHeader("Cache-Control", "no-store"); response.AppendHeader("Cache-Control", "must-revalidate"); response.AppendHeader("Cache-Control", "max-stale=0"); response.AppendHeader("Cache-Control", "post-check=0"); response.AppendHeader("Cache-Control", "pre-check=0"); response.AppendHeader("Pragma", "no-cache"); response.Cache.SetCacheability(HttpCacheability.NoCache); response.Cache.SetNoStore(); response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1)); } response.AppendHeader("Expires", DateTime.Now.AddMinutes(-1).ToLongDateString()); response.AppendHeader("Keep-Alive", "timeout=3, max=993"); response.AddHeader("content-disposition", "attachment; filename=\"" + fileName + "\""); response.ContentType = contentType;}I will write another blog soon with some more details about XSL-FO and how to create the PDF's dynamically.Please do re-tweet if you find this interest :)

Oracle SQL Developer Data Modeler: What Tables Aren’t In At Least One SubView?

- by thatjeffsmith

Organizing your data model makes the information easier to consume. One of the organizational tools provided by Oracle SQL Developer Data Modeler is the ‘SubView.’ In a nutshell, a SubView is a subset of your model. The Challenge: I’ve just created a model which represents my entire ____________ application. We’ll call it ‘residential lending.’ Instead of having all 100+ tables in a single model diagram, I want to break out the tables by module, e.g. appraisals, credit reports, work histories, customers, etc. I’ve spent several hours breaking out the tables to one or more SubViews, but I think i may have missed a few. Is there an easy way to see what tables aren’t in at least ONE subview? The Answer Yes, mostly. The mostly comes about from the way I’m going to accomplish this task. It involves querying the SQL Developer Data Modeler Reporting Schema. So if you don’t have the Reporting Schema setup, you’ll need to do so. Got it? Good, let’s proceed. Before you start querying your Reporting Schema, you might need a data model for the actual reporting schema…meta-meta data! You could reverse engineer the data modeler reporting schema to a new data model, or you could just reference the PDFs in \datamodeler\reports\Reporting Schema diagrams directory. Here’s a hint, it’s THIS one The Query Well, it’s actually going to be at least 2 queries. We need to get a list of distinct designs stored in your repository. For giggles, I’m going to get a listing including each version of the model. So I can query based on design and version, or in this case, timestamp of when it was added to the repository. We’ll get that from the DMRS_DESIGNS table: SELECT DISTINCT design_name, design_ovid, date_published FROM DMRS_designs Then I’m going to feed the design_ovid, down to a subquery for my child report. select name, count(distinct diagram_id) from DMRS_DIAGRAM_ELEMENTS where design_ovid = :dESIGN_OVID and type = 'Table' group by name having count(distinct diagram_id) < 2 order by count(distinct diagram_id) desc Each diagram element has an entry in this table, so I need to filter on type=’Table.’ Each design has AT LEAST one diagram, the master diagram. So any relational table in this table, only having one listing means it’s not in any SubViews. If you have overloaded object names, which is VERY possible, you’ll want to do the report off of ‘OBJECT_ID’, but then you’ll need to correlate that to the NAME, as I doubt you’re so intimate with your designs that you recognize the GUIDs So I’m going to cheat and just stick with names, but I think you get the gist. My Model Of my almost 90 tables, how many of those have I not added to at least one SubView? Now let’s run my report! Voila! My ‘BEER2′ table isn’t in any SubView! It says ’1′ because the main model diagram counts as a view. So if the count came back as ’2′, that would mean the table was in the main model diagram and in 1 SubView diagram. And I know what you’re thinking, what kind of residential lending program would have a table called ‘BEER2?’ Let’s just say, that my business model has some kinks to work out!

SQL SERVER – SOS_SCHEDULER_YIELD – Wait Type – Day 8 of 28

- by pinaldave

This is a very interesting wait type and quite often seen as one of the top wait types. Let us discuss this today. From Book On-Line: Occurs when a task voluntarily yields the scheduler for other tasks to execute. During this wait the task is waiting for its quantum to be renewed. SOS_SCHEDULER_YIELD Explanation: SQL Server has multiple threads, and the basic working methodology for SQL Server is that SQL Server does not let any “runnable” thread to starve. Now let us assume SQL Server OS is very busy running threads on all the scheduler. There are always new threads coming up which are ready to run (in other words, runnable). Thread management of the SQL Server is decided by SQL Server and not the operating system. SQL Server runs on non-preemptive mode most of the time, meaning the threads are co-operative and can let other threads to run from time to time by yielding itself. When any thread yields itself for another thread, it creates this wait. If there are more threads, it clearly indicates that the CPU is under pressure. You can fun the following DMV to see how many runnable task counts there are in your system. SELECT scheduler_id, current_tasks_count, runnable_tasks_count, work_queue_count, pending_disk_io_count FROM sys.dm_os_schedulers WHERE scheduler_id < 255 GO If you notice a two-digit number in runnable_tasks_count continuously for long time (not once in a while), you will know that there is CPU pressure. The two-digit number is usually considered as a bad thing; you can read the description of the above DMV over here. Additionally, there are several other counters (%Processor Time and other processor related counters), through which you can refer to so you can validate CPU pressure along with the method explained above. Reducing SOS_SCHEDULER_YIELD wait: This is the trickiest part of this procedure. As discussed, this particular wait type relates to CPU pressure. Increasing more CPU is the solution in simple terms; however, it is not easy to implement this solution. There are other things that you can consider when this wait type is very high. Here is the query where you can find the most expensive query related to CPU from the cache Note: The query that used lots of resources but is not cached will not be caught here. SELECT SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1, ((CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(qt.TEXT) ELSE qs.statement_end_offset END - qs.statement_start_offset)/2)+1), qs.execution_count, qs.total_logical_reads, qs.last_logical_reads, qs.total_logical_writes, qs.last_logical_writes, qs.total_worker_time, qs.last_worker_time, qs.total_elapsed_time/1000000 total_elapsed_time_in_S, qs.last_elapsed_time/1000000 last_elapsed_time_in_S, qs.last_execution_time, qp.query_plan FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp ORDER BY qs.total_worker_time DESC -- CPU time You can find the most expensive queries that are utilizing lots of CPU (from the cache) and you can tune them accordingly. Moreover, you can find the longest running query and attempt to tune them if there is any processor offending code. Additionally, pay attention to total_worker_time because if that is also consistently higher, then the CPU under too much pressure. You can also check perfmon counters of compilations as they tend to use good amount of CPU. Index rebuild is also a CPU intensive process but we should consider that main cause for this query because that is indeed needed on high transactions OLTP system utilized to reduce fragmentations. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All of the discussions of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark (TOTD #184)

- by arungupta

TOTD #183 explained how to build a WebSocket-driven application using GlassFish 4. This Tip Of The Day (TOTD) will explain how do view/debug on-the-wire messages, or frames as they are called in WebSocket parlance, over this upgraded connection. This blog will use the application built in TOTD #183. First of all, make sure you are using a browser that supports WebSocket. If you recall from TOTD #183 then WebSocket is combination of Protocol and JavaScript API. A browser supporting WebSocket, or not, means they understand your web pages with the WebSocket JavaScript. caniuse.com/websockets provide a current status of WebSocket support in different browsers. Most of the major browsers such as Chrome, Firefox, Safari already support WebSocket for the past few versions. As of this writing, IE still does not support WebSocket however its planned for a future release. Viewing WebSocket farmes require special settings because all the communication happens over an upgraded HTTP connection over a single TCP connection. If you are building your application using Java, then there are two common ways to debug WebSocket messages today. Other language libraries provide different mechanisms to log the messages. Lets get started! Chrome Developer Tools provide information about the initial handshake only. This can be viewed in the Network tab and selecting the endpoint hosting the WebSocket endpoint. You can also click on "WebSockets" on the bottom-right to show only the WebSocket endpoints. Click on "Frames" in the right panel to view the actual frames being exchanged between the client and server. The frames are not refreshed when new messages are sent or received. You need to refresh the panel by clicking on the endpoint again. To see more detailed information about the WebSocket frames, you need to type "chrome://net-internals" in a new tab. Click on "Sockets" in the left navigation bar and then on "View live sockets" to see the page. Select the box with the address to your WebSocket endpoint and see some basic information about connection and bytes exchanged between the client and the endpoint. Clicking on the blue text "source dependency ..." shows more details about the handshake. If you are interested in viewing the exact payload of WebSocket messages then you need a network sniffer. These tools are used to snoop network traffic and provide a lot more details about the raw messages exchanged over the network. However because they provide lot more information so they need to be configured in order to view the relevant information. Wireshark (nee Ethereal) is a pretty standard tool for sniffing network traffic and will be used here. For this blog purpose, we'll assume that the WebSocket endpoint is hosted on the local machine. These tools do allow to sniff traffic across the network though. Wireshark is quite a comprehensive tool and we'll capture traffic on the loopback address. Start wireshark, select "loopback" and click on "Start". By default, all traffic information on the loopback address is displayed. That includes tons of TCP protocol messages, applications running on your local machines (like GlassFish or Dropbox on mine), and many others. Specify "http" as the filter in the top-left. Invoke the application built in TOTD #183 and click on "Say Hello" button once. The output in wireshark looks like Here is a description of the messages exchanged: Message #4: Initial HTTP request of the JSP page Message #6: Response returning the JSP page Message #16: HTTP Upgrade request Message #18: Upgrade request accepted Message #20: Request favicon Message #22: Responding with favicon not found Message #24: Browser making a WebSocket request to the endpoint Message #26: WebSocket endpoint responding back You can also use Fiddler to debug your WebSocket messages. How are you viewing your WebSocket messages ? Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish Subsequent blogs will discuss the following topics (not necessary in that order) ... Binary data as payload Custom payloads using encoder/decoder Error handling Interface-driven WebSocket endpoint Java client API Client and Server configuration Security Subprotocols Extensions Other topics from the API

PetaPoco with parameterised stored procedure and Asp.Net MVC

- by Jalpesh P. Vadgama

I have been playing with Micro ORMs as this is very interesting things that are happening in developer communities and I already liked the concept of it. It’s tiny easy to use and can do performance tweaks. PetaPoco is also one of them I have written few blog post about this. In this blog post I have explained How we can use the PetaPoco with stored procedure which are having parameters. I am going to use same Customer table which I have used in my previous posts. For those who have not read my previous post following is the link for that. Get started with ASP.NET MVC and PetaPoco PetaPoco with stored procedures Now our customer table is ready. So let’s Create a simple process which will fetch a single customer via CustomerId. Following is a code for that. CREATE PROCEDURE mysp_GetCustomer @CustomerId as INT AS SELECT * FROM [dbo].Customer where CustomerId=@CustomerId Now we are ready with our stored procedures. Now lets create code in CustomerDB class to retrieve single customer like following. using System.Collections.Generic; namespace CodeSimplified.Models { public class CustomerDB { public IEnumerable<Customer> GetCustomers() { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; return databaseContext.Query<Customer>("exec mysp_GetCustomers"); } public Customer GetCustomer(int customerId) { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; var customer= databaseContext.SingleOrDefault<Customer>("exec mysp_GetCustomer @customerId",new {customerId}); return customer; } } } Here in above code you can see that I have created a new method call GetCustomer which is having customerId as parameter and then I have written to code to use stored procedure which we have created to fetch customer Information. Here I have set EnableAutoSelect=false because I don’t want to create Select statement automatically I want to use my stored procedure for that. Now Our Customer DB class is ready and now lets create a ActionResult Detail in our controller like following using System.Web.Mvc; namespace CodeSimplified.Controllers { public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return View(); } public ActionResult Customer() { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomers()); } public ActionResult Details(int id) { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomer(id)); } } } Now Let’s create view based on that ActionResult Details method like following. Now everything is ready let’s test it in browser. So lets first goto customer list like following. Now I am clicking on details for first customer and Let’s see how we can use the stored procedure with parameter to fetch the customer details and below is the output. So that’s it. It’s very easy. Hope you liked it. Stay tuned for more..Happy Programming

Keep a Window on top with a handy AutoHotkey script

- by Matthew Guay

Are you tired of shuffling back and forth between windows to get your work done? Here’s a handy tool that lets you keep any window always on top when you need it. There are many ways to use multiple windows efficiently, but sometimes it seems you need to keep a smaller one in front of a larger window and they never quite fit right. Whether you’re trying to use Calculator and a web form at the same time, or see what music is playing while you’re catching up on your news, there’s many scenarios where it can be useful to keep one window always on top. There are many utilities to do this, but they are often needlessly complicated and bloated. Here we look at a better solution from Amit, our friend at Digital Inspiration. Always on Top Thanks to AutoHotkey, you can easily always keep any window on top of all the others on your screen. You can download this as a small exe and run it directly, or can create it with a simple script in AutoHotkey. For simplicity, we simply downloaded the application and ran it directly. To do this, download Always on Top (link below), and unzip the file. Once you’ve launched it, simply select the window you want to keep on top and press Ctrl+Space. This program will now stay in front, even when it is not the active window. Here’s a screenshot of a Hotmail signup dialog in Chrome with Notepad kept on top. Notice Notepad isn’t the active application, but it is still on top. If you wish to un-pin the window from being on top, simply select the window and press Ctrl+space again. You can keep multiple windows pinned at once, too, though you may clutter your desktop quickly! Always on Top will keep running in your system tray, and you can exit or suspend it by right-clicking on its tray icon and selecting exit or suspend, respectively. Create Your Own Always on Top Utility with AutoHotkey If you’re a fan of AutoHotkey, you can create your own AutoHotkey script to keep windows on top simply and easily with only one line of code: ^SPACE:: Winset, Alwaysontop, , A Simply create a new file, insert the code, and save it as plaintext with the .ahk file extension. If you have AutoHotkey installed, simply double-click this file for the exact same functionality as the premade version. Conclusion This is a great way to keep a window handy, and it can be beneficial in many scenarios. For instance you can use it to copy data from a PDF or image into a form or spreadsheet, and it saves a lot of clicks and time.

How to Sync Any Browser’s Bookmarks With Your iPad or iPhone

- by Chris Hoffman

Apple makes it easy to synchronize bookmarks between the Safari browser on a Mac and the Safari browser on iOS, but you don’t have to use Safari — or a Mac — to sync your bookmarks back and forth. You can do this with any browser. Whether you’re using Chrome, Firefox, or even Internet Explorer, there’s a way to sync your browser bookmarks so you can access your same bookmarks on your iPad. Safari on a Mac Apple’s iCloud service is the officially supported way to sync data with your iPad or iPhone. It’s included on Macs, but Apple also offers similar iCloud bookmark syncing features for Windows. On a Mac, this should be enabled by default. To check whether it’s enabled, you can launch the System Preferences panel on your Mac, open the iCloud preferences panel, and ensure the Safari option is checked. If you’re using Safari on Windows — well, you shouldn’t be. Apple is no longer updating Safari for Windows. iCloud allows you to synchronize bookmarks between other browsers on your Windows system and Safari on your iOS device, so Safari isn’t necessary. Internet Explorer, Firefox, or Chrome via iCloud To get started, download Apple’s iCloud Control Panel application for Windows and install it. Launch the iCloud Control Panel and log in with the same iCloud account (Apple ID) you use on your iPad or iPhone. You’ll be able to enable Bookmark syncing with Internet Explorer, Firefox, or Chrome. Click the Options button to select the browser you want to synchronize bookmarks with. (Note that bookmarks are called “favorites” in Internet Explorer.) You’ll be able to access your synced bookmarks in the Safari browser on your iPad or iPhone, and they’ll sync back and forth automatically over the Internet. Google Chrome Sync Google Chrome also has its own built-in sync feature and Google provides an official Chrome app for iPad and iPhone. If you’re a Chrome user, you can set up Chrome Sync on your desktop version of Chrome — you should already have this enabled if you have logged into your Chrome browser. You can check if this Chrome Sync is enabled by opening Chrome’s settings screen and seeing whether you’re signed in. Click the Advanced sync settings button and ensure bookmark syncing is enabled. Once you have Chrome Sync set up, you can install the Chrome app from the App Store and sign in with the same Google account. Your bookmarks, as well as other data like your open browser tabs, will automatically sync. This can be a better solution because the Chrome browser is available for so many platforms and you gain the ability to synchronize other browser data, such as your open browser tabs, between your devices. Unfortunately, the Chrome browser is slower than Apple’s own Safari browser on iPad and iPhone because of the way Apple limits third-party browsers, so using it involves a trade-off. Manual Bookmark Sync in iTunes iTunes also allows you to sync bookmarks between your computer and your iPad or iPhone. It does this the old-fashioned way, by initiating a manual sync when your device is plugged in via USB. To access this option, connect your device to your computer, select the device in iTunes, and click the Info tab. This is the more outdated way of synchronizing your bookmarks. This feature may be useful if you want to create a one-time copy of your bookmarks from your PC, but it’s nowhere near ideal for regular syncing. You don’t have to use this feature, just as you really don’t have to use iTunes anymore. In fact, this option is unavailable if you’ve set up iCloud syncing in iTunes. After you set up bookmark syncing via iCloud or Chrome Sync, bookmarks will sync immediately after you save, remove, or edit them.

How to Browse Without a Trace with an Ubuntu Live CD

- by Trevor Bekolay

No matter how diligently you clear your cache and erase your history, web browsing leaves traces on your computer. If you need keep your browsing private, then an Ubuntu Live CD is the answer. The key to this trick is that the Live CD environment runs completely in RAM, so things like your cache, cookies, and history don’t get saved to a persistent storage location. On a hard drive, even deleted files can be recovered, but once a computer is turned off the data stored in RAM is unrecoverable. In addition, since the Ubuntu Live CD environment is the same no matter what computer you use it on, there’s very little identifying information that a website can use to track you! The first step is to either burn an Ubuntu Live CD, or prepare a non-persistent Ubuntu USB flash drive. Ubuntu treats non-persistent flash drives like CDs, so files will not be written to it, but if you’re paranoid, then using a physical CD ensures that nothing gets written to a storage device. Boot up from the CD or flash drive, and choose to Run Ubuntu from the CD or flash drive if prompted (for more detailed instructions on booting from a CD or USB drive, see this article, or our guide on booting from a flash drive even if your BIOS won’t let you). Once the graphical Ubuntu environment comes up, you can click on the Firefox icon at the top of the screen to start browsing. If your browsing requires Flash, then you can install it by clicking on System at the top-left of the screen, then Administration > Synaptic Package Manager. Click on Settings at the top of the Synaptic window, and then select Repositories. Add a check in the checkbox with the label ending in “multiverse”. Click Close. Click the Reload button in the main Synaptic window. The list of available packages will reload. When they’ve reloaded, type “restricted” in the Quick search box. Right-click on ubuntu-restricted-extras and select Mark for Installation. It will note a number of other packages that will be installed. This list includes audio and video codecs, so after installing these, you should be able to play downloaded movies and songs. Click Mark to accept the installation of these other packages. Once you return to the main Synaptic window, click the Apply button and go through the dialogs to finish the installation of Flash and the other useful packages. If you open up Firefox now, you’ll have no problems using websites that use Flash. When you’re done browsing and shut down or restart your computer, all traces of your web browsing will be gone. It’s a bit of work compared to just using a privacy-centric browser, but if it’s very important that your browsing leave no traces on your hard drive, an Ubuntu Live CD is your best bet.

Change Desktop Resolution With a Keyboard Shortcut

- by Matthew Guay

Do you find yourself changing your monitor resolution several times a day? If so, you might like this handy way to set a keyboard shortcut for your most-used resolutions. Most users rarely have to change their screen resolution often, as LCD monitors usually only look best at their native resolution. But netbooks present a unique situation, as their native resolution is usually only 1024×600. Some newer netbooks offer higher resolutions which may not looks as crisp as the native resolution but can be handy for using a program that expects a higher resolution. This is the perfect situation for a keyboard shortcut to help you change the resolution without having to hassle with dialogs and menus each time, and HRC – HotKey Resolution Changer makes it easy to do. Create Keyboard Shortcuts Download the HRC – HotKey Resolution Changer (link below), unzip, and then run HRC.exe in the folder. This will start a tray icon, and will not automatically open the HRC window. You don’t have to install HRC. Double-click the tray icon to open it. Note: Windows 7 automatically hides new tray icons, so if you can’t see it, click the arrow to see the hidden tray icons. By default, HRC will show two entries with your default resolutions, color depth, and refresh rate. Add a keyboard shortcut by clicking the Change button over the resolution. Press the keyboard shortcut you want to press to switch to that resolution; we entered Ctrl+Alt+1 for our default resolution. Make sure not to use a keyboard shortcut you use in another application, as this will override it. Click Set when you’ve entered the hotkey(s) you want. Now, on the second entry, select the resolution you want for your alternate resolution. The drop-down list will only show your monitor’s supported resolutions, so you don’t have to worry about choosing an incorrect resolution. You can also set a different color depth or refresh rate for this resolution. Now add a keyboard shortcut for this resolution as well. You can set keyboard shortcuts for up to 9 different resolutions with HRC. Click the Select number of HotKeys button on the left, and choose the number of resolutions you want to set. Here we have unique keyboard shortcuts for our three most-used resolutions on our netbook. HRC must be kept running to use the keyboard shortcuts, so click the Minimize to tray icon which is the second icon to the right. This will keep it running in the tray. If you want to be able to change your resolution anytime, you’ll want HRC to automatically start with Windows. Create a shortcut to HRC, and paste it into your Windows startup folder. You can easily open this folder by entering the following in the Run command or in the address bar in Explorer: %appdata%\Microsoft\Windows\Start Menu\Programs\Startup Conclusion HRC- HotKey Resolution Changer gives you a great way to quickly change your screen resolution with a keyboard shortcut. Whether or not you love keyboard shortcuts, this is still a much easier way to switch between your most commonly used resolutions.

Windows Azure Use Case: Agility

- by BuckWoody

This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx Description: Agility in this context is defined as the ability to quickly develop and deploy an application. In theory, the speed at which your organization can develop and deploy an application on available hardware is identical to what you could deploy in a distributed environment. But in practice, this is not always the case. Having an option to use a distributed environment can be much faster for the deployment and even the development process. Implementation: When an organization designs code, they are essentially becoming a Software-as-a-Service (SaaS) provider to their own organization. To do that, the IT operations team becomes the Infrastructure-as-a-Service (IaaS) to the development teams. From there, the software is developed and deployed using an Application Lifecycle Management (ALM) process. A simplified view of an ALM process is as follows: Requirements Analysis Design and Development Implementation Testing Deployment to Production Maintenance In an on-premise environment, this often equates to the following process map: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including physical plant, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to on-premise Testing servers. If no server capacity available, more resources procured through standard budgeting and ordering processes. Manual and automated functional, load, security, etc. performed. Deployment to Production Server team involved to select platform and environments with available capacity. If no server capacity available, standard budgeting and procurement process followed. If no server capacity available, systems built, configured and put under standard organizational IT control. Systems configured for proper operating systems, patches, security and virus scans. System maintenance, HA/DR, backups and recovery plans configured and put into place. Maintenance Code changes evaluated and altered according to need. In a distributed computing environment like Windows Azure, the process maps a bit differently: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including budget, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to Azure. Manual and automated functional, load, security, etc. performed. Deployment to Production Code deployed to Azure. Point in time backup and recovery plans configured and put into place.(HA/DR and automated backups already present in Azure fabric) Maintenance Code changes evaluated and altered according to need. This means that several steps can be removed or expedited. It also means that the business function requesting the application can be held directly responsible for the funding of that request, speeding the process further since the IT budgeting process may not be involved in the Azure scenario. An additional benefit is the “Azure Marketplace”, In effect this becomes an app store for Enterprises to select pre-defined code and data applications to mesh or bolt-in to their current code, possibly saving development time.

Understanding Collabnet’s LDAP binding

- by Robert May

We want to use both subversion usernames and passwords as well as Active Directory for our authentication on our Collabnet subversion server. This has proven to be more of a challenge than we thought, mostly because Collabnet’s documentation is pretty poor. To supplement that documentation, I add my own. The first thing to understand is that the attribute that you specify in the LDAP Login Attribute ONLY applies to lookups done for the user. It does NOT apply to the LDAP Bind DN field. Second, know that the debug logs (error is the one you want) don’t give you debug information for the bind DN, just the login attempts. Third, by default, Active Directory does not allow anonymous binds, so you MUST put in a user that has the authority to query the Active Directory ldap. Because of these items, the values to set in those fields can be somewhat confusing. You’ll want to have ADSI Edit handy (I also used ldp, which is installed by default on server 2008), since ADSI Edit can help you find stuff in your active directory. Be careful, you can also break stuff. Here’s what should go into those fields. LDAP Security Level: Should be set to None LDAP Server Host: Should be set to the full name of a domain controller in your domain. For example, dc.mydomain.com LDAP Server Port: Should be set to 3268. The default port of 389 will only query that specific server, not the global catalog. By setting it to 3268, the global catalog will be queried, which is probably what you want. LDAP Base DN: Should be set to the location where you want the search for users to begin. By default, the search scope is set to sub, so all child organizational units below this setting will be searched. In my case, I had created an OU specifically for users for group policies. My value ended up being: OU=MyOu,DC=domain,DC=org. However, if you’re pointing it to the default Users folder, you may end up with something like CN=Users,DC=domain,DC=org (or com or whatever). Again, use ADSI edit and use the Distinguished Name that it shows. LDAP Bind DN: This needs to be the Distinguished Name of the user that you’re going to use for binding (i.e. the user you’ll be impersonating) for doing queries. In my case, it ended up being CN=svn svn,OU=MyOu,DC=domain,DC=org. Why the double svn, you might ask? That’s because the first and last name fields are set to svn and by default, the distinguished name is the first and last name fields! That’s important. Its NOT the username or account name! Again, use ADSI edit, browse to the username you want to use, right click and select properties, and then search the attributes for the Distinguished Name. Once you’ve found that, select it and click View and you can copy and paste that into this field. LDAP Bind Password: This is the password for the account in the Bind DN LDAP login Attribute: sAMAccountName. If you leave this blank, uid is used, which may not even be set. This tells it to use the Account Name field that’s defined under the account tab for users in Active Directory Users and Computers. Note that this attribute DOES NOT APPLY to the LDAP Bind DN. You must use the full distinguished name of the bind DN. This attribute allows users to type their username and password for authentication, rather than typing their distinguished name, which they probably don’t know. LDAP Search Scope: Probably should stay at sub, but could be different depending on your situation. LDAP Filter: I left mine blank, but you could provide one to limit what you want to see. LDP would be helpful for determining what this is. LDAP Server Certificate Verification: I left it checked, but didn’t try it without it being checked. Hopefully, this will save some others pain when trying to get Collabnet setup. Technorati Tags: Subversion,collabnet
