  • Advantages of SQL Backup Pro

    - by Grant Fritchey
    Getting backups of your databases in place is a fundamental issue for protection of the business. Yes, I said business, not data, not databases, but business. Because of a lack of good, tested, backups, companies have gone completely out of business or suffered traumatic financial loss. That’s just a simple fact (outlined with a few examples here). So you want to get backups right. That’s a big part of why we make Red Gate SQL Backup Pro work the way it does. Yes, you could just use native backups, but you’ll be missing a few advantages that we provide over and above what you get out of the box from Microsoft. Let’s talk about them. Guidance If you’re a hard-core DBA with 20+ years of experience on every version of SQL Server and several other data platforms besides, you may already know what you need in order to get a set of tested backups in place. But, if you’re not, maybe a little help would be a good thing. To set up backups for your servers, we supply a wizard that will step you through the entire process. It will also act to guide you down good paths. For example, if your databases are in Full Recovery, you should set up transaction log backups to run on a regular basis. When you choose a transaction log backup from the Backup Type you’ll see that only those databases that are in Full Recovery will be listed: This makes it very easy to be sure you have a log backup set up for all the databases you should and none of the databases where you won’t be able to. There are other examples of guidance throughout the product. If you have the responsibility of managing backups but very little knowledge or time, we can help you out. Throughout the software you’ll notice little green question marks. You can see two in the screen above and more in each of the screens in other topics below this one. Clicking on these will open a window with additional information about the topic in question which should help to guide you through some of the tougher decisions you may have to make while setting up your backup jobs. Here’s an example: Backup Copies As a part of the wizard you can choose to make a copy of your backup on your network. This process runs as part of the Red Gate SQL Backup engine. It will copy your backup, after completing the backup so it doesn’t cause any additional blocking or resource use within the backup process, to the network location you define. Creating a copy acts as a mechanism of protection for your backups. You can then backup that copy or do other things with it, all without affecting the original backup file. This requires either an additional backup or additional scripting to get it done within the native Microsoft backup engine. Offsite Storage Red Gate offers you the ability to immediately copy your backup to the cloud as a further, off-site, protection of your backups. It’s a service we provide and expose through the Backup wizard. Your backup will complete first, just like with the network backup copy, then an asynchronous process will copy that backup to cloud storage. Again, this is built right into the wizard or even the command line calls to SQL Backup, so it’s part a single process within your system. With native backup you would need to write additional scripts, possibly outside of T-SQL, to make this happen. Before you can use this with your backups you’ll need to do a little setup, but it’s built right into the product to get this done. You’ll be directed to the web site for our hosted storage where you can set up an account. Compression If you have SQL Server 2008 Enterprise, or you’re on SQL Server 2008R2 or greater and you have a Standard or Enterprise license, then you have backup compression. It’s built right in and works well. But, if you need even more compression then you might want to consider Red Gate SQL Backup Pro. We offer four levels of compression within the product. This means you can get a little compression faster, or you can just sacrifice some CPU time and get even more compression. You decide. For just a simple example I backed up AdventureWorks2012 using both methods of compression. The resulting file from native was 53mb. Our file was 33mb. That’s a file that is smaller by 38%, not a small number when we start talking gigabytes. We even provide guidance here to help you determine which level of compression would be right for you and your system: So for this test, if you wanted maximum compression with minimum CPU use you’d probably want to go with Level 2 which gets you almost as much compression as Level 3 but will use fewer resources. And that compression is still better than the native one by 10%. Restore Testing Backups are vital. But, a backup is just a file until you restore it. How do you know that you can restore that backup? Of course, you’ll use CHECKSUM to validate that what was read from disk during the backup process is what gets written to the backup file. You’ll also use VERIFYONLY to check that the backup header and the checksums on the backup file are valid. But, this doesn’t do a complete test of the backup. The only complete test is a restore. So, what you really need is a process that tests your backups. This is something you’ll have to schedule separately from your backups, but we provide a couple of mechanisms to help you out here. First, when you create a backup schedule, all done through our wizard which gives you as much guidance as you get when running backups, you get the option of creating a reminder to create a job to test your restores. You can enable this or disable it as you choose when creating your scheduled backups. Once you’re ready to schedule test restores for your databases, we have a wizard for this as well. After you choose the databases and restores you want to test, all configurable for automation, you get to decide if you’re going to restore to a specified copy or to the original database: If you’re doing your tests on a new server (probably the best choice) you can just overwrite the original database if it’s there. If not, you may want to create a new database each time you test your restores. Another part of validating your backups is ensuring that they can pass consistency checks. So we have DBCC built right into the process. You can even decide how you want DBCC run, which error messages to include, limit or add to the checks being run. With this you could offload some DBCC checks from your production system so that you only run the physical checks on your production box, but run the full check on this backup. That makes backup testing not just a general safety process, but a performance enhancer as well: Finally, assuming the tests pass, you can delete the database, leave it in place, or delete it regardless of the tests passing. All this is automated and scheduled through the SQL Agent job on your servers. Running your databases through this process will ensure that you don’t just have backups, but that you have tested backups. Single Point of Management If you have more than one server to maintain, getting backups setup could be a tedious process. But, with Red Gate SQL Backup Pro you can connect to multiple servers and then manage all your databases and all your servers backups from a single location. You’ll be able to see what is scheduled, what has run successfully and what has failed, all from a single interface without having to connect to different servers. Log Shipping Wizard If you want to set up log shipping as part of a disaster recovery process, it can frequently be a pain to get configured correctly. We supply a wizard that will walk you through every step of the process including setting up alerts so you’ll know should your log shipping fail. Summary You want to get your backups right. As outlined above, Red Gate SQL Backup Pro will absolutely help you there. We supply a number of processes and functionalities above and beyond what you get with SQL Server native. Plus, with our guidance, hints and reminders, you will get your backups set up in a way that protects your business.

  • Does software architect/designer require more skills and intellectual than software engineer (implementation)?

    - by Amumu
    So I heard the positions for designing software and writing spec for developers to implement are higher and getting paid more. I think many companies are using the Software Engineering title to depict the person to implement software, which means using tools and technologies to write the actual code. I know that in order to be a software architecture, one needs to be good at implementation in order to have an architectural overview of a system using a set of specific technologies. This is different than I thought of a Software Engineer. My thinking is similar to the standard of IEEE: A software engineer is an engineer who is capable of going from requirement analysis until the software is deployed, based on the SWEBOK (IEEE). Just look at the table of content. The IEEE even has the certificate for Software Engineering, since ABET (Accreditation Board for Engineering and Technology) seems to not have an official qualification test for Software Engineer (although IEEE is a member of ABET). The two certificates are CSDA and CSDP. I intend to take on these two examination in the future to be qualified as a software engineer, although I am already working as one (Junior position). On a side note on the issues of Software Engineer, you can read the dicussion here: Just a Programmer and Just a Software Engineer. The information of ABET does not accredit Software Engineer is in "Just a Software Engineer". On the other hand, why is Programmer/Softwar Engineer who writes code considered a low level position? Suppose if two people have equal skills after the same years of experience, one becomes a software architect and one keeps focus on implementation aspect of Software Engineering (of course he also has design skill to compose a system, since he's a software engineer as well, but maybe less than the specialized software architect), how comes work from Software Engineer is less complicated than the Software Architect? In order to write great code with turn design into reality, it requires far greater skill than just understanding a particular language and a framework. I don't think the ones who wrote and contributing Linux OS are lower level job and easier than conceptual design and writing spec. Can someone enlighten me?

  • Handling EJB/JPA exceptions in a “beautiful” way

    - by Rodrigues, Raphael
    In order to handle JPA exceptions, there are some ways already detailed in lots of blogs. Here, I intend to show one of them, which I consider kind of “beauty”. My use case has a unique constraint, when the User try to create a duplicate value in database. The JPA throws a java.sql.SQLIntegrityConstraintViolationException, and I have to catch it and replace the message. In fact, ADF Business Components framework already has a beautiful solution for this very well documented here . However, for EJB/JPA there's no similar approach. In my case, what I had to do was: 1. Create a custom Error Handler Class in DataBindings file; a. Here is how you accomplish it. 2. Override the reportException method and check if the type of exception exists on property file a. If yes, I change the message and rethrows the exception b. If not, go on the execution The main goal of this approach is whether a new or unhandled Exception was raised, the job is, only create a single entry in bundle property file. Here are pictures step by step: 1. CustomExceptionHandler.java 2. Databindings.cpx 3. Bundle file 4. jspx: 5. Stacktrace: Give your opinion, what did you think about that?

  • I want to make video games, but I hate coding

    - by hoper
    I know this sounds eally crazy. However, I just want to ask. Now, I am studying C++ code in my school (My major is computer programming). Honestly, my grade is not so good, and assignments are really hard. Sometimes, I feel sad that I will spend 8~10 hours per day for coding (which is stressful) at the future for my job. But, I still want to make video games. Maybe this is the only one reason why I am taking all of stressful courses. I always write down plots, stories, characters, fictional gaming worlds. Once, I thought I should study artistic technology such as game design program not computer technology such as C++, C#, etc. However, most of popular game designers(or directors) such as Kojima, Miyamoto Shigeru, etc used to be good programmers. And, companies actaully assign programmers to directors because they understand how to make a game. I try to find other colleges or universities where teach game design program. However, one article that lists rank 10 game design schools in North America seems untrustful because the survey company only scores it from intervews of students. (Once, I tried to attend Art Institute of Vancouver which is rank 7 according to that article. However, one programmer who used to be an instructor in there told me the truth. That is the employement rate of graduated students is low) Do you guys have any advice for me?

  • Unity stuck in 2D mode, Nvidia Quadro graphics "unknown", Nvidia-Current active but not in use

    - by Jordan Lund
    I've seen this problem reported under several questions, but I haven't been able to resolve any of it so I thought I'd bring it all in under one umbrella. I started a new job and was given a Dell Precision M6400 laptop with Nvidia Quadro FX 2700M graphics card. It had a previous version of Ubuntu on it, but nobody had any passwords for it so I wiped the drive and did a fresh install of 11.10 from scratch. I didn't do any updates during installation, preferring to do them after boot. Updates ran fine and the system works... except Unity is in 2D mode. System Settings - Additional Drivers shows that Nvidia-Current is active but not in use. System Settings - System Info shows Graphics Driver Unknown, Experience Standard Nvidia X Server Settings is installed and working, re-writing the xorg.conf did nothing. /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro FX 2700M/PCI/SSE2 OpenGL version string: 3.3.0 NVIDIA 285.05.09 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes One suggestion was to do a sudo apt-get --purge remove nvidia* and that resulted in a scrambled screen on boot and a non-bootable installation. Pressing the Delete key on boot allowed me to access the recovery console and do a sudo apt-get install nvidia-current, which brought me back to a working, bootable system. Another suggestion was to edit /etc/default/grub and change the line reading "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to read "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=192MB" thus allocating more video RAM. I did that, followed by a sudo update-grub and a re-boot. No change. Created a brand new standard user and logged on with that account, no change.

  • Pro BizTalk 2009

    - by Sean Feldman
    I have finished reading Pro BizTalk 2009 book from APress. This is a great book  if you’ve never dealt with BizTalk in the past and want to have a quick “on-ramp”. Although the book is very concerned about right way of building traditional BizTalk applications, it also dedicates a chapter to ESB Toolkit and does a good job in analyzing it. The fact that authors were concerned with subject such as coupling, hard-coding, automation, etc. makes it very interesting. One warning, if you are expecting to have a book that will guide you how to apply step by step examples, forget it. Nor this book does it, neither it’s possible due to multiple erratas found in it. I really was disappointed by the number of typos, inaccuracies, and technical mistakes. These kind of things turn readers away, especially when they had no experience with BT in the past. But this is the only bad thing about it. As for the rest – great content. Next week I am taking a deep dive course on BizTalk 2009. I really feel that this book has helped me a lot to get my feet wet. Next target will be ESB Tookit. To get to that, I will use what the book authors wrote “you have to understand how BizTalk as an engine works”.

  • Writing a Book, and Moving my Blog

    - by Ben Nevarez
    I started blogging about SQL Server here at SQLblog back in July, 2009 and it was a lot of fun, I enjoyed it a lot. Then later, after a series of blog posts about the Query Optimizer, I was invited to write an entire book about that same topic. But after a few months I realized that it was going to be hard to continue both blogging and writing chapters for a book, this in addition to my regular day job, so I decided to stop blogging for a little while.   Now that I have finished the last chapter of the book and I am working on the final chapter reviews, I decided to start blogging again. This time I am moving my blog to   http://www.benjaminnevarez.com   Same as my previous posts I plan to write about my topics of interest, like the relational engine, and basically anything related to SQL Server. Hopefully you find my new blog interesting and useful.   Finally, I would like to thank Adam for allowing me to blog here.

  • Loading a Template From a User Control

    - by Ricardo Peres
    What if you wanted to load a template (ITemplate property) from an external user control (.ascx) file? Yes, it is possible; there are a number of ways to do this, the one I'll talk about here is through a type converter. You need to apply a TypeConverterAttribute to your ITemplate property where you specify a custom type converter that does the job. This type converter relies on InstanceDescriptor. Here is the code for it: public class TemplateTypeConverter: TypeConverter { public override Boolean CanConvertFrom(ITypeDescriptorContext context, Type sourceType) { return ((sourceType == typeof(String)) || (base.CanConvertFrom(context, sourceType) == true)); } public override Boolean CanConvertTo(ITypeDescriptorContext context, Type destinationType) { return ((destinationType == typeof(InstanceDescriptor)) || (base.CanConvertTo(context, destinationType) == true)); } public override Object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, Object value, Type destinationType) { if (destinationType == typeof(InstanceDescriptor)) { Object objectFactory = value.GetType().GetField("_objectFactory", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(value); Object builtType = objectFactory.GetType().BaseType.GetField("_builtType", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(objectFactory); MethodInfo loadTemplate = typeof(TemplateTypeConverter).GetMethod("LoadTemplate"); return (new InstanceDescriptor(loadTemplate, new Object [] { "~/" + (builtType as Type).Name.Replace('_', '/').Replace("/ascx", ".ascx") })); } return base.ConvertTo(context, culture, value, destinationType); } public static ITemplate LoadTemplate(String virtualPath) { using (Page page = new Page()) { return (page.LoadTemplate(virtualPath)); } } } And, on your control: public class MyControl: Control { [Browsable(false)] [TypeConverter(typeof(TemplateTypeConverter))] public ITemplate Template { get; set; } } This allows the following declaration: Hope this helps! SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.brushes.Xml.aliases = ['xml']; SyntaxHighlighter.all();

  • On mobile is there a reason why processes are often short lived and must persist their state explicitly?

    Most mobile platforms (such as Android, iOS, Windows phone 7 and I believe the new WinRT) can kill inactive application processes under memory pressure. To prevent this from affecting the user experience applications are expected to save and restore their state as their process is killed and restarted. Having application processes killed in this way makes the developers job harder. On various occasions I've seen a mobile app that would: Return to the welcome screen each time I switch back to it. Crash when I switch back to it (possibly accessing some state that no longer exists after the process was killed) Misbehave when I switch back to it (sometimes requiring a restart or tasks killer to fix) Otherwise misbehave in some hard to reproduce way (e.g. android service killed and restarted at the wrong time) I don't really understand why these mobile operating systems are designed to kill tasks in this way especially since it makes application development more difficult and error prone. Desktop operating systems don't kill processes like that. They swap out unused pages of memory to mass storage. Is there a reason why the same approach isn't used on mobile? Mobile hardware is only a few years behind PC hardware in term of performance. I'm sure there are very good reasons why mobile operating systems are designed this way. If you can point me to a paper or blog post that explain these reasons or can give me some insight I'd very much appreciate it.

  • Stupid Geek Tricks: Compare Your Browser’s Memory Usage with Google Chrome

    - by The Geek
    Ever tried to figure out exactly how much memory Google Chrome or Internet Explorer is using? Since they each show up a bunch of times in Task Manager, it’s not so easy! Here’s the quick and easy way to compare them. Both Chrome and IE use multiple processes to isolate tabs from each other, to make sure that one tab doesn’t kill the whole browser. Firefox, on the other hand, just uses a single process for everything. Rather than pulling out a calculator and adding them all up, you can just open up Google Chrome, and type in about:memory into the location bar to see a full list of each browser’s memory usage.   On my test system with 6 GB of system RAM, I’m running the Development channel version of Chrome, and I’ve got about 40 different tabs open, which is why the memory usage is so high. Firefox has 8 tabs open, and IE is enjoying being opened for the first time in forever. Want to help cut down on memory usage and keep your Chrome browser running fast? Disable all unnecessary extensions, and then make sure you disable any plug-ins that you don’t need either.

  • F# performance vs Erlang performance, is there proof the Erlang's VM is faster?

    - by afuzzyllama
    I've been putting time into learning functional programming and I've come to the part where I want to start writing a project instead of just dabbling in tutorials/examples. While doing my research, I've found that Erlang seems to be a pretty powerful when it comes to writing concurrent software (which is my goal), but resources and tools for development aren't as mature as Microsoft development products. F# can run on linux (Mono) so that requirement is met, but while looking around on the internet I cannot find any comparisons of F# vs Erlang. Right now, I am leaning towards Erlang just because it seems to have the most press, but I am curious if there is really any performance difference between the two languages. Since I am use to developing in .NET, I can probably get up to speed with F# a lot faster than Erlang, but I cannot find any resource to convince me that F# is just as scalable as Erlang. I am most interested in simulation, which is going to be firing a lot of quickly processed messages to persistant nodes. If I have not done a good job with what I am trying to ask, please ask for more verification.

  • Why is IaaS important in Azure&hellip;

    - by Steve Loethen
    Three weeks ago, Microsoft released the next phase of Azure.  I have had several clients waiting on this release.  The fact that they have been waiting and are now more receptive to looking at the cloud.  Customers expressed fear of the unknown.  And a fear of lack of control, even when that lack of control also means a huge degree of flexibility to innovate with concerns about the underlying infrastructure.  I think IaaS will be that “gateway drug” to get customers who have been hesitant to take another look at the cloud.  The dialog can change from the cloud being this big scary unknown to a resource for workloads.  The conversations should have always been, and can know be even stronger, geared toward the following points: 1) The cloud is not unicorns and glitter, the cloud is resources.  Compute, storage, db’s, services bus, cache…..  Like many of the resources we have on-premise.  Not magic, just another resource with advantages and obstacles like any other resource. 2) The cloud should be part of the conversation for any new project.  All of the same criteria should be applied, on-premise or off.  Cost, security, reliability, scalability, speed to deploy, cost of licenses, need to customize image, complex workloads.  We have been having these discussions for years when we talk about on-premise projects.  We make decisions on OS’s, Databases, ESB’s, configuration and products based on a myriad of factors.  We use the same factors but now we have a additional set of resources to consider in our process. 3) The cloud is a great solution looking for some interesting problems.  It is our job to recognize the right problems that fit into the cloud, weigh the factors and decide what to do. IaaS makes this discussion easier, offers more choices, and often choices that many enterprises will find more better than PaaS.  Looking forward to helping clients realize the power of the cloud.

  • Service Level Loggin/Tracing

    - by Ahsan Alam
    We all love to develop services, right? First timers want to learn technologies like WCF and Web Services. Some simply want to build services; whereas, others may find services as natural architectural decision for particular systems. Whatever the reason might be, services are commonly used in building wide range of systems. Developers often encapsulates various functionality (small or big) within one or more services, and expose them for multiple applications. Sometimes from day one (and definitely over time) these services may evolve into a set of black boxes. Services or not, black boxes or not, issues and exceptions are sometimes hard to avoid, especially in highly evolving and transactional systems. We can try to be methodical with our unit testing, QA and overall process; but we may not be able to avoid some type of system issues. When issues arise from one or more highly transactional services, it becomes necessary to resolve them very quickly. When systems handle thousands of transaction in matter of hours, some issues may not surface immediately. That is when service level logging becomes very useful. Technologies such as WCF, allow us to enable service level tracing with minimal effort; but that may not provide us with complete picture. Developers may need to add tracing within critical areas of the code with various degrees of verbosity. Programmer can always utilize some logging framework such as the 'Logging Application Block' to get the job done. It may seem overkill sometimes; but I have noticed from my experience that service level logging helps programmer trace many issues very quickly.

  • Career Advice for a career shifter

    - by newbie
    Hi! I am an industrial engineer and last May 2010 at the age of 25, I resigned from my job and decided to have a career shift to IT. I am studying again and so far learned the basics of the following programming languages: C, Java (SE), MySql, html, css, javascript. I am really just a beginner in everything and only have little knowledge on data structures / algorithms, software engineering and network systems. I am currently focusing all my attention to Java so that I'll have at least one expertise. And so far, i could only make small games like hangman and battleship. I will finish my 1 year diploma in IT this May and I need to know what kinds of jobs should I apply to start my career as an IT practitioner (application developer)? I am really confused and afraid because I am already old and I need to begin again my career from scratch and I don't know where to start. Where should I start???? Thank you very much. Your reply would be highly appreciated.

  • SQL Sharding and SQL Azure&hellip;

    - by Dave Noderer
    Herve Roggero has just published a paper that outlines patterns for scaling using SQL Azure and the Blue Syntax (he and Scott Klein’s company) sharding api. You can find the paper at: http://www.bluesyntax.net/files/EnzoFramework.pdf Herve and Scott have also just released an Apress book Pro SQL Azure. The idea of being able to split (shard) database operations automatically and control them from a web based management console is very appealing. These ideas have been talked about for a long time and implemented in thousands of very custom ways that have been costly, complicated and fragile. Now, there is light at the end of the tunnel. Scaling database access will become easier and move into the mainstream of application development. The main cost is using an api whenever accessing the database. The api will direct the query to the correct database(s) which may be located locally or in the cloud. It is inevitable that the api will change in the future, perhaps incorporated into a Microsoft offering. Even if this is the case, your application has now been architected to utilize these patterns and details of the actual api will be less important. Herve does a great job of laying out the concepts which every developer and architect should be familiar with!

  • Professionalism of online username / handle

    - by Thanatos
    I have in the past, and continue currently, used the handle "thanatos" on a lot of Internet sites, and if that isn't available (which happens ~50% of the time), "deathanatos". "Thanatos" is the name of the Greek god or personification of death (not to be confused with Hades, the Greek god of the underworld). "Dea" is a natural play-on-words to make the handle work in situations where the preferred handle has already been taken, without having to resort to numbers and remaining pronounceable. I adopted the handle many years ago — at the time, I was reading Edith Hamilton's Mythology, and Piers Anthony's On a Pale Horse, both still favorites of mine, and the name was born out of that. When I created the handle, I was fairly young, and valued privacy while online, not giving out my name. As I've become a more competent programmer, I'm starting to want to release some of my private works under FOSS licenses and such, and sometimes under my own name. This has started to tie this handle with my real name. I've become increasingly aware of my "web image" in the last few years, as I've been job hunting. As a programmer, I have a larger-than-average web presence, and I've started to wonder: Is this handle name professional? Does a handle name matter in a professional sense? Should I "rebrand"? (While one obviously wants to avoid hateful or otherwise distasteful names, is a topic such as "death" (to which my name is tied) proper? What could be frowned upon?) To try to make this a bit more programmer specific: Programmers are online — a lot — and some of us (and some who are not us) tend to put emphasis on a "web presence". I would argue that a prudent programmer (or anyone in an occupation that interacts online a lot) would be aware of their web presence. While not strictly limited to just programmers, for better or worse, it is a part of our world.

  • What I&rsquo;m Reading &ndash; 2 &ndash; Microsoft Silverlight 4 Data and Services Cookbook

    - by Dave Campbell
    A while back I mentioned that I had a couple books on my desktop that I’ve been “shooting holes” in … in other words, reading pieces that are interesting at the time, or looking something up rather than starting at the front and heading for the back. The book I want to mention today is Microsoft Silverlight 4 Data and Services Cookbook : by Gill Cleeren and Kevin Dockx. As opposed to the authors of the last book I reviewed, I don’t personally know Gill or Kevin, but I’ve blogged a lot of their articles… both prolific and on-topic writers. The ‘recipe’ style of the book shouldn’t put you off. It’s more of the way the chapters are laid out than anything else and once you see one of them, you recognize the pattern. This is a great eBook to have around to open when you need to find something useful. As with the other PACKT book I talked about have the eBook because for technical material, at least lately, I’ve gravitated toward that. I can have it with me on a USB stick at work, or at home. Read the free chapter then check out their blogs. You may be surprised by some of the items you’ll find inside the covers. One such nugget is one I don’t think I’ve seen blogged:  “Converting You Existing Applications to Use Silverlight”. Another good job! Technorati Tags: Silverlight 4

  • Asus Sonic Master on Asus N53SV

    - by David Winchester
    I have read that there's a problem to get the subwoofer working in these laptops. I tried this solution No sound from external subwoofer but I don't how to prove that the subwoofer is properly functioning. I use Pulseaudio equalizer and the bass sound seems to work fine, but when I go to the Sound Settings, I can't move the bar where it says 'Subwoofer' in my sound card option, so I don't know if everything is alright. If someone has a solution I would like to know, because there isn't much information regarding this. By the way, I'm using Ubuntu 12.04 64 bits. Thanks beforehand, Dave EDIT ----------- Possible Solution Well, I will post a solution that worked for me and I think it will help a lot of users. I finally got the subwoofer working. Besides adding in /etc/modprobe.d/alsa-base.conf the line options snd-hda-intel model=asus-mode4 I deleted the lines with load-module module-combine and module-combine-sink in /etc/pulse/default.pa (in the home folder there's also a ~/.pulse/default.pa file, I don't know if it has the lines too) To assure all the channels are working, I think this command tells me that speaker-test -c6 -l1 -twav I use pulseaudio-equalizer and the bass sounds very well when properly adjusted. Also, all the channels seems to work fine and the sound is even better than in Windows (where I don't have an equalizer). I pointed out before a module-combine and module-combine-sink problem, because one day I turned on my laptop and pulseaudio didn't work. So I deleted the lines with that names (don't know if they came by default, maybe I added them sometime when I was trying to fix my speakers). After all this, I can now move the Subwoofer bar in the Sound configuration. Anyways, the Equalizer does a great job and it improves the sound a lot.

  • Geek it Up

    - by BuckWoody
    I’ve run into a couple of kinds of folks in IT. Some really like technology a lot – a whole lot –and others treat it more as a job. For those of you in the second camp, you can go back to your drab, meaningless jobs – this post is for the first group. I’m a geek. Not a little bit of a geek, a really big one. I love technology, I get excited about science and electronics in general, and I read math books when I don’t have to. Yes, I have a Star Trek item or two around the house. My daughter is fluent in both Monty Python AND Serenity. I totally admit it. So if you’re like me (OK, maybe a little less geeky than that), then go for it. Put those toys in your cubicle, wear your fan shirt, but most of all, geek up your tools. No, this isn’t an April Fool’s post – I really mean it. I’ve noticed that when I get the larger monitor, better mouse, cooler keyboard, I LIKE coming to work. It’s a way to reward yourself – I’ve even found that it makes work easier if I have the kind of things I enjoy around to work with. So buy that old “clicky” IBM keyboard, get three monitors, and buy a nice headset so that you can set all of your sounds to Monty Python WAV’s. And get to work.

  • You Might Be a SharePoint Professional If&hellip;

    - by Mark Rackley
    I really think no explanation is needed. Hope this makes you smile.. Thanks again for being an awesome SharePoint community! If you can only dream about working an 8 hour day, there’s a good chance you are a SharePoint professional. You might be a SharePoint professional if the last time you heard “Old MacDonald Had a Farm” you wondered “How many web front ends does it have?” If you consider Twitter the best form of support since the dawn of the Internet, you might be a SharePoint professional. If you are giddy-as-a-school-girl excited about going to Anaheim in October and it has NOTHING to do with Disneyland, you might be a SharePoint professional. You might be a SharePoint professional if you own more SharePoint shirts than you do pairs of underwear. If you’ve thought of giving up a career in the IT world for a job taking orders at a fast food chain, you might be a SharePoint professional. You might be a SharePoint professional if the only people who understand the words that come out of your mouth are other SharePoint people. If you put the word “Share” or “SP” in front of EVERYTHING (ShareFood, SPRunner, etc… etc…) then you might be a SharePoint professional. You are probably a SharePoint professional if you love SharePoint.. you hate SharePoint… you love SharePoint… you hate SharePoint… If the only thing you’d rather do more than SharePoint is SharePint, then you are definitely a SharePoint professional. You might be a SharePoint professional if your idea of name dropping is “Andrew Connell says…” or “According to Todd Klindt”… or even “Well, when I was stuck in a Turkish prison with Joel Oleson…”

  • C#: String Concatenation vs Format vs StringBuilder

    - by James Michael Hare
    I was looking through my groups’ C# coding standards the other day and there were a couple of legacy items in there that caught my eye.  They had been passed down from committee to committee so many times that no one even thought to second guess and try them for a long time.  It’s yet another example of how micro-optimizations can often get the best of us and cause us to write code that is not as maintainable as it could be for the sake of squeezing an extra ounce of performance out of our software. So the two standards in question were these, in paraphrase: Prefer StringBuilder or string.Format() to string concatenation. Prefer string.Equals() with case-insensitive option to string.ToUpper().Equals(). Now some of you may already know what my results are going to show, as these items have been compared before on many blogs, but I think it’s always worth repeating and trying these yourself.  So let’s dig in. The first test was a pretty standard one.  When concattenating strings, what is the best choice: StringBuilder, string concattenation, or string.Format()? So before we being I read in a number of iterations from the console and a length of each string to generate.  Then I generate that many random strings of the given length and an array to hold the results.  Why am I so keen to keep the results?  Because I want to be able to snapshot the memory and don’t want garbage collection to collect the strings, hence the array to keep hold of them.  I also didn’t want the random strings to be part of the allocation, so I pre-allocate them and the array up front before the snapshot.  So in the code snippets below: num – Number of iterations. strings – Array of randomly generated strings. results – Array to hold the results of the concatenation tests. timer – A System.Diagnostics.Stopwatch() instance to time code execution. start – Beginning memory size. stop – Ending memory size. after – Memory size after final GC. So first, let’s look at the concatenation loop: 1: // build num strings using concattenation. 2: for (int i = 0; i < num; i++) 3: { 4: results[i] = "This is test #" + i + " with a result of " + strings[i]; 5: } Pretty standard, right?  Next for string.Format(): 1: // build strings using string.Format() 2: for (int i = 0; i < num; i++) 3: { 4: results[i] = string.Format("This is test #{0} with a result of {1}", i, strings[i]); 5: }   Finally, StringBuilder: 1: // build strings using StringBuilder 2: for (int i = 0; i < num; i++) 3: { 4: var builder = new StringBuilder(); 5: builder.Append("This is test #"); 6: builder.Append(i); 7: builder.Append(" with a result of "); 8: builder.Append(strings[i]); 9: results[i] = builder.ToString(); 10: } So I take each of these loops, and time them by using a block like this: 1: // get the total amount of memory used, true tells it to run GC first. 2: start = System.GC.GetTotalMemory(true); 3:  4: // restart the timer 5: timer.Reset(); 6: timer.Start(); 7:  8: // *** code to time and measure goes here. *** 9:  10: // get the current amount of memory, stop the timer, then get memory after GC. 11: stop = System.GC.GetTotalMemory(false); 12: timer.Stop(); 13: other = System.GC.GetTotalMemory(true); So let’s look at what happens when I run each of these blocks through the timer and memory check at 500,000 iterations: 1: Operator + - Time: 547, Memory: 56104540/55595960 - 500000 2: string.Format() - Time: 749, Memory: 57295812/55595960 - 500000 3: StringBuilder - Time: 608, Memory: 55312888/55595960 – 500000   Egad!  string.Format brings up the rear and + triumphs, well, at least in terms of speed.  The concat burns more memory than StringBuilder but less than string.Format().  This shows two main things: StringBuilder is not always the panacea many think it is. The difference between any of the three is miniscule! The second point is extremely important!  You will often here people who will grasp at results and say, “look, operator + is 10% faster than StringBuilder so always use StringBuilder.”  Statements like this are a disservice and often misleading.  For example, if I had a good guess at what the size of the string would be, I could have preallocated my StringBuffer like so:   1: for (int i = 0; i < num; i++) 2: { 3: // pre-declare StringBuilder to have 100 char buffer. 4: var builder = new StringBuilder(100); 5: builder.Append("This is test #"); 6: builder.Append(i); 7: builder.Append(" with a result of "); 8: builder.Append(strings[i]); 9: results[i] = builder.ToString(); 10: }   Now let’s look at the times: 1: Operator + - Time: 551, Memory: 56104412/55595960 - 500000 2: string.Format() - Time: 753, Memory: 57296484/55595960 - 500000 3: StringBuilder - Time: 525, Memory: 59779156/55595960 - 500000   Whoa!  All of the sudden StringBuilder is back on top again!  But notice, it takes more memory now.  This makes perfect sense if you examine the IL behind the scenes.  Whenever you do a string concat (+) in your code, it examines the lengths of the arguments and creates a StringBuilder behind the scenes of the appropriate size for you. But even IF we know the approximate size of our StringBuilder, look how much less readable it is!  That’s why I feel you should always take into account both readability and performance.  After all, consider all these timings are over 500,000 iterations.   That’s at best  0.0004 ms difference per call which is neglidgable at best.  The key is to pick the best tool for the job.  What do I mean?  Consider these awesome words of wisdom: Concatenate (+) is best at concatenating.  StringBuilder is best when you need to building. Format is best at formatting. Totally Earth-shattering, right!  But if you consider it carefully, it actually has a lot of beauty in it’s simplicity.  Remember, there is no magic bullet.  If one of these always beat the others we’d only have one and not three choices. The fact is, the concattenation operator (+) has been optimized for speed and looks the cleanest for joining together a known set of strings in the simplest manner possible. StringBuilder, on the other hand, excels when you need to build a string of inderterminant length.  Use it in those times when you are looping till you hit a stop condition and building a result and it won’t steer you wrong. String.Format seems to be the looser from the stats, but consider which of these is more readable.  Yes, ignore the fact that you could do this with ToString() on a DateTime.  1: // build a date via concatenation 2: var date1 = (month < 10 ? string.Empty : "0") + month + '/' 3: + (day < 10 ? string.Empty : "0") + '/' + year; 4:  5: // build a date via string builder 6: var builder = new StringBuilder(10); 7: if (month < 10) builder.Append('0'); 8: builder.Append(month); 9: builder.Append('/'); 10: if (day < 10) builder.Append('0'); 11: builder.Append(day); 12: builder.Append('/'); 13: builder.Append(year); 14: var date2 = builder.ToString(); 15:  16: // build a date via string.Format 17: var date3 = string.Format("{0:00}/{1:00}/{2:0000}", month, day, year); 18:  So the strength in string.Format is that it makes constructing a formatted string easy to read.  Yes, it’s slower, but look at how much more elegant it is to do zero-padding and anything else string.Format does. So my lesson is, don’t look for the silver bullet!  Choose the best tool.  Micro-optimization almost always bites you in the end because you’re sacrificing readability for performance, which is almost exactly the wrong choice 90% of the time. I love the rules of optimization.  They’ve been stated before in many forms, but here’s how I always remember them: For Beginners: Do not optimize. For Experts: Do not optimize yet. It’s so true.  Most of the time on today’s modern hardware, a micro-second optimization at the sake of readability will net you nothing because it won’t be your bottleneck.  Code for readability, choose the best tool for the job which will usually be the most readable and maintainable as well.  Then, and only then, if you need that extra performance boost after profiling your code and exhausting all other options… then you can start to think about optimizing.
