• android third party libraries

  - by Terrance

  Its hard to believe that there aren't a ton of awesome third party (possibly open source) libraries out on the web for android using java but, I cant say I have found a great many so far but, droid seems like the only notable one I've come across. Any other majorly useful android libraries out there? Sorry in advanced if there is a dupe out there somewhere (seems like there should be) but if there is by all means post it and let me know.

• To disallow indexing the category and tag listings in a blog

  - by Mert Nuhoglu

  Mark Wilson says that category and tag listings in a blog should be disallowed in order to prevent duplicate content. I understand this. However, I want to put internal links on keywords in the blog posts to the tag and category pages in order for the readers to find more relevant content. I wonder whether putting those internal links to the category/tag pages which are disallowed in robots.txt is counted as useful from the perspective of SEO internal linking?

• Something similar to Objective-C categories in other languages?

  - by adig

  I understand Objective-C categories and how they become useful, but I always have a hard time explaining the concept to other programmers that are not familiar with Objective C. Maybe I'm just bad at explaining things, but I was thinking at another way to explain it by comparing to similar features offered by other (more popular) languages. (ex : I can explain the similarities between Objective C protocols and Java Interfaces) Any examples similar to Categories ?

• Emacs keybindings for texboxes in firefox?

  - by Seamus

  I'm so used to emacs that sometimes, when I'm typing something in a textbox in firefox, I sometimes try and do C-p to move up a line. It is seriously annoying to have to cancel a print dialog box every time I try and move about my text. If it's not horrendously complicated, I'd like to have keybindings that emulate emacs inside textboxes in firefox... Obviously, I wouldn't need all the keybindings, but movement, marking, killing and yanking would be useful. Is this an insane request?

• Modifying Contiguous Time Periods in a History Table

  Alex Kuznetsov is credited with a clever technique for creating a history table for SQL that is designed to store contiguous time periods and check that these time periods really are contiguous, using nothing but constraints. This is now increasingly useful with the DATE data type in SQL Server. The modification of data in this type of table isn't always entirely intuitive so Alex is on hand to give a brief explanation of how to do it.

• What's the best language combo for code generation?

  - by Peter Turner

  I read through Code Generation in Action but never bothered to make anything of it because Ruby just doesn't fit with my lifestyle at this juncture. The book came out more on the cusp of the C# revolution, and it said that C# "was a language designed to be generated", apparently using Ruby as the generator language. In your experience, what is the ideal combination of languages to generate the most useful code?

• Northwind now available on SQL Azure

  - by jamiet

  Two weeks ago I made available a copy of [AdventureWorks2012] on SQL Azure and published credentials so that anyone from the SQL community could connect up and experience SQL Azure, probably for the first time. One of the (somewhat) popular requests thereafter was to make the venerable Northwind database available too so I am pleased to say that as of right now, Northwind is up there too. You will notice immediately that all of the Northwind tables (and the stored procedures and views too) have been moved into a schema called [Northwind] – this was so that they could be easily differentiated from the existing [AdventureWorks2012] objects. I used an SQL Server Data Tools (SSDT) project to publish the schema and data up to this SQL Azure database; if you are at all interested in poking around that SSDT project then I have made it available on Codeplex for your convenience under the MS-PL license – go and get it from https://northwindssdt.codeplex.com/. Using SSDT proved particularly useful as it alerted me to some aspects of Northwind that were not compatible with SQL Azure, namely that five of the tables did not have clustered indexes: The beauty of using SSDT is that I am alerted to these issues before I even attempt a connection to SQL Azure. Pretty cool, no? Fixing this situation was of course very easy, I simply changed the following primary keys from being nonclustered to clustered: [PK_Region] [PK_CustomerDemographics] [PK_EmployeeTerritories] [PK_Territories] [PK_CustomerCustomerDemo]   If you want to connect up then here are the credentials that you will need: Server mhknbn2kdz.database.windows.net Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly You will need SQL Server Management Studio (SSMS) 2008R2 installed in order to connect or alternatively simply use this handy website: https://mhknbn2kdz.database.windows.net which provides a web interface to a SQL Azure server. Do remember that hosting this database is not free so if you find that you are making use of it please help to keep it available by visiting Paypal and donating any amount at all to [email protected]. To make this easy you can simply hit this link and the details will be completed for you – all you have to do is login and hit the “Send” button. If you are already a PayPal member then it should take you all of about 20 seconds! I hope this is useful to some of you folks out there. Don’t forget that we also have more data up there than in the conventional [AdventureWorks2012], read more at Big AdventureWorks2012. @Jamiet  AdventureWorks on Azure - Provided by the SQL Server community, for the SQL Server community!

  - by Taylor Gibb

  Disabling the Control Panel is a pretty common thing for admins to do. Here is how to do it in Windows 8 using both Group Policy as well as a manual registry hack. It’s worth noting that this is something you probably won’t want to do on your home computer. But it’s useful to understand how it works in case yours is disabled and you want to enable it again.

• web vs desktop? (php vs c++?)

  - by Dhaivat Pandya

  I need to write a simple file transfer mechanism (that isn't ftp). Firstly, it must have a GUI. Secondly, it must not be dropbox. Third, it may not use any paid libraries, and hopefully, it uses open source components. The question that came to my mind is, where is everyone moving, from desktop to web, or from web to desktop? Would it be more useful to be experienced in say, C++ than in PHP (or vice versa)?

• Improve Performance of char.IsWhiteSpace for ASCII inputs in .NET 3.5

  - by Tanzim Saqib

  IsNullOrWhiteSpace is a new method introduced in string class in .NET 4.0. While this is a very useful method in string based processing, I attempted to implement it in .NET 3.5 using char.IsWhiteSpace() . I have found significant performance penalty using this method which I replaced later on, with my version. The following code takes about 20.6074219 seconds in my machine whereas my implementation of char.IsWhiteSpace takes about 1/4 less time 15.8271485 seconds only. In many scenarios ex. string...(read more)

• How to check SERP position correctly?

  - by Cengiz Frostclaw

  I wonder how do you check your website's SERP position for a certain query. I cannot directly go to Google and search, because it knows i'm looking for my site, and it shows it in the first position, but from another browser, it cannot be even in the first page. So how do you check for "average user" ? I use Tor browser for that, since it gives me a completely different IP, do you think is it safe? I mean, does it give useful information ?

• Checking who is connected to your server, with PowerShell.

  - by Fatherjack

  There are many occasions when, as a DBA, you want to see who is connected to your SQL Server, along with how they are connecting and what sort of activities they are carrying out. I’m going to look at a couple of ways of getting this information and compare the effort required and the results achieved of each. SQL Server comes with a couple of stored procedures to help with this sort of task – sp_who and its undocumented counterpart sp_who2. There is also the pumped up version of these called sp_whoisactive, written by Adam Machanic which does way more than these procedures. I wholly recommend you try it out if you don’t already know how it works. When it comes to serious interrogation of your SQL Server activity then it is absolutely indispensable. Anyway, back to the point of this blog, we are going to look at getting the information from sp_who2 for a remote server. I wrote this Powershell script a week or so ago and was quietly happy with it for a while. I’m relatively new to Powershell so forgive both my rather low threshold for entertainment and the fact that something so simple is a moderate achievement for me. $Server = 'SERVERNAME' $SMOServer = New-Object Microsoft.SQLServer.Management.SMO.Server $Server # connection and query stuff         $ConnectionStr = "Server=$Server;Database=Master;Integrated Security=True" $Query = "EXEC sp_who2" $Connection = new-object system.Data.SQLClient.SQLConnection $Table = new-object "System.Data.DataTable" $Connection.connectionstring = $ConnectionStr try{ $Connection.open() $Command = $Connection.CreateCommand() $Command.commandtext = $Query $result = $Command.ExecuteReader() $Table.Load($result) } catch{ # Show error $error[0] | format-list -Force } $Title = "Data access processes (" + $Table.Rows.Count + ")" $Table | Out-GridView -Title $Title $Connection.close() So this is pretty straightforward, create an SMO object that represents our chosen server, define a connection to the database and a table object for the results when we get them, execute our query over the connection, load the results into our table object and then, if everything is error free display these results to the PowerShell grid viewer. The query simply gets the results of ‘EXEC sp_who2′ for us. Depending on how many connections there are will influence how long the query runs. The grid viewer lets me sort and search the results so it can be a pretty handy way to locate troublesome connections. Like I say, I was quite pleased with this, it seems a pretty simple script and was working well for me, I have added a few parameters to control the output and give me more specific details but then I see a script that uses the $SMOServer object itself to provide the process information and saves having to define the connection object and query specifications. $Server = 'SERVERNAME' $SMOServer = New-Object Microsoft.SQLServer.Management.SMO.Server $Server $Processes = $SMOServer.EnumProcesses() $Title = "SMO processes (" + $Processes.Rows.Count + ")" $Processes | Out-GridView -Title $Title Create the SMO object of our server and then call the EnumProcesses method to get all the process information from the server. Staggeringly simple! The results are a little different though. Some columns are the same and we can see the same basic information so my first thought was to which runs faster – so that I can get my results more quickly and also so that I place less stress on my server(s). PowerShell comes with a great way of testing this – the Measure-Command function. All you have to do is wrap your piece of code in Measure-Command {[your code here]} and it will spit out the time taken to execute the code. So, I placed both of the above methods of getting SQL Server process connections in two Measure-Command wrappers and pressed F5! The Powershell console goes blank for a while as the code is executed internally when Measure-Command is used but the grid viewer windows appear and the console shows this. You can take the output from Measure-Command and format it for easier reading but in a simple comparison like this we can simply cross refer the TotalMilliseconds values from the two result sets to see how the two methods performed. The query execution method (running EXEC sp_who2 ) is the first set of timings and the SMO EnumProcesses is the second. I have run these on a variety of servers and while the results vary from execution to execution I have never seen the SMO version slower than the other. The difference has varied and the time for both has ranged from sub-second as we see above to almost 5 seconds on other systems. This difference, I would suggest is partly due to the cost overhead of having to construct the data connection and so on where as the SMO EnumProcesses method has the connection to the server already in place and just needs to call back the process information. There is also the difference in the data sets to consider. Let’s take a look at what we get and where the two methods differ Query execution method (sp_who2) SMO EnumProcesses Description - Urn What looks like an XML or JSON representation of the server name and the process ID SPID Spid The process ID Status Status The status of the process Login Login The login name of the user executing the command HostName Host The name of the computer where the  process originated BlkBy BlockingSpid The SPID of a process that is blocking this one DBName Database The database that this process is connected to Command Command The type of command that is executing CPUTime Cpu The CPU activity related to this process DiskIO - The Disk IO activity related to this process LastBatch - The time the last batch was executed from this process. ProgramName Program The application that is facilitating the process connection to the SQL Server. SPID1 - In my experience this is always the same value as SPID. REQUESTID - In my experience this is always 0 - Name In my experience this is always the same value as SPID and so could be seen as analogous to SPID1 from sp_who2 - MemUsage An indication of the memory used by this process but I don’t know what it is measured in (bytes, Kb, Mb…) - IsSystem True or False depending on whether the process is internal to the SQL Server instance or has been created by an external connection requesting data. - ExecutionContextID In my experience this is always 0 so could be analogous to REQUESTID from sp_who2. Please note, these are my own very brief descriptions of these columns, detail can be found from MSDN for columns in the sp_who results here http://msdn.microsoft.com/en-GB/library/ms174313.aspx. Where the columns are common then I would use that description, in other cases then the information returned is purely for interpretation by the reader. Rather annoyingly both result sets have useful information that the other doesn’t. sp_who2 returns Disk IO and LastBatch information which is really useful but the SMO processes method give you IsSystem and MemUsage which have their place in fault diagnosis methods too. So which is better? On reflection I think I prefer to use the sp_who2 method primarily but knowing that the SMO Enumprocesses method is there when I need it is really useful and I’m sure I’ll use it regularly. I’m OK with the fact that it is the slower method because Measure-Command has shown me how close it is to the other option and that it really isn’t a large enough margin to matter.
