  • Benefits of programming (doing) versus reading blogs (thinking?)

    - by Xian
    I have come to a conclusion or realization that perhaps many developers I know including myself have a fanatical fascination with reading as many programming and technology blogs or listening to podcasts as humanly possible. I sometimes wonder if this time would be much better spent in actual coding and doing, rather than the incessant thinking and perhaps wondering what the "other guy" is doing? With a very large signal to noise ratio in most blogs and podcasts, is there real benefit in maintaining a huge and constant blog role.. or is this some primal fear or instinct to keep up the pace unless being left behind? Can they simply be relegated to Google search and just-in-time learning? Edit: (There are some amazing answers here and touch a philosophical nerve with me, if you are reading this for the first time, I recommend taking the time reading through the answers below)

  • Programming pattern to flatten deeply nested ajax callbacks?

    - by chiborg
    I've inherited JavaScript code where the success callback of an Ajax handler initiates another Ajax call where the success callback may or may not initiate another Ajax call. This leads to deeply nested anonymous functions. Maybe there is a clever programming pattern that avoids the deep-nesting and is more DRY. jQuery.extend(Application.Model.prototype, { process: function() { jQuery.ajax({ url:myurl1, dataType:'json', success:function(data) { // process data, then send it back jQuery.ajax({ url:myurl2, dataType:'json', success:function(data) { if(!data.ok) { jQuery.ajax({ url:myurl2, dataType:'json', success:mycallback }); } else { mycallback(data); } } }); } }); } });

  • How can I set up .NET UnhandledException handling in a Windows service?

    - by Mike Pateras
    protected override void OnStart(string[] args) { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Thread.Sleep(10000); throw new Exception(); } void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { } I attached a debugger to the above code in my windows service, setting a breakpoint in CurrentDomain_UnhandledException, but it was never hit. The exception pops up saying that it is unhandled, and then the service stops. I even tried putting some code in the event handler, in case it was getting optimized away. Is this not the proper way to set up unhandled exception handling in a windows service?

  • Cannot login to SQL Server 2008 R2 with Windows authentication

    - by Ian Boyd
    When i try to connect to SQL Server (2008 R2) using Windows authentication: i cannot: Checking the Windows Application event log, i find the error: Login failed for user 'AVATOPIA\ian'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: ] Log Name: Application Source: MSSQLSERVER Event ID: 18456 Level: Information User: AVATOPIA\ian OpCode: Task Category: Logon i can login to the computer itself using Windows authentication. i can log into SQL Server using the local Windows Administrator account. We can connect to 8 other SQL Servers on the domain using Windows Authentication. Just this one, whitch is the only one that is 2008 R2 is failing. So i assume it's a bug with *2008 R2. Note: i cannot logon locally, or remotely, using Windows authentication. i can login locally and remotely using SQL Server Authentication. Update Note: It's not limited to SQL Server Management Studio, standalone applications that connect using Windows authentication: fail: Note: It's not a client problem, as we can connect fine to other (non-SQL Server 2008 R2 machines): i'm sure there's a technote or knowledge base article describing why SQL Server 2008 R2 is broken by default, but i can't find it. Update 2 Matt figure out the change that Microsoft made so that SQL Server 2008 R2 is broken by default: Administrators are no longer administrators All that remains is to figure out how to make Administrators administrators. One of these days i'm going to start a list of changes around Microsoft's "broken by default" initiative. Steps to reproduce the problem How do i add a group to the sysadmin fixed server role? Here's the steps i try, that don't work: Click Add: Click Object Types: Ensure that you have no ability to add groups: and click OK. Under Enter the object names to select, enter Administrators: Click Check Names, and ensure that you are not allowed to add groups: and click Cancel. Click Browse..., and ensure that you have no ability to add groups: You should now still not have added any group to the sysadmin role. Additional information SQL Server Management Studio is being run as an administrator: SQL Server is set to use Windows Authentication: tried while logged into SQL with both sa and the only other sysadmin domain account (screenshot can be supplied for those who don't believe)

  • Is it possible to capture a window with windows 7 DWM thumbnail in it?

    - by Dogan Demir
    I am starting to believe that you can do nothing with Windows API. I have two windows. One has a DWM thumbnail in it. What I want to do is, I want to be able to capture the screen of the window with the thumbnail into the other one. When I do this, using bitblt, everything is copied except the thumbnail. It just isn't there in the bitmap. So how does the DWM rendering work? I mean, if DWM renders thumbnails directly onto the DC of the registered window, then my approach should work. I'm confused. Thanks a bunch.

  • RTL (Arabic and Hebrew) Support for Windows Phone 7

    - by Daniel Moth
    Problem and Background Currently there is no support for Right-To-Left rendering in Windows Phone 7, when developing with Silverlight (itself built on .NET Compact Framework). When I encountered that limitation, I had a flashback to 2005 when I complained about the luck of RTL on NETCF. Unfortunately, the partial solution I proposed back then requires PInvoke and there is no such support on Windows Phone today. Fortunately, my RTL requirements this time were more modest: all I wanted to do was display correctly a translation (of Hebrew or Arabic) in my FREE WP7 translator app. For v1.0 of the app, the code received a string from the service and just put it up on the screen as the translated text. In Arabic and Hebrew, that string (incorrectly) appeared reversed. I knew that, but decided that since it is a platform limitation, I could live with it and so could the users. Yuval P, a colleague at Microsoft, pushed me to offer support for Hebrew (something that I wasn't motivated to pursue if I am honest). After many back and forths, we landed on some code that works. It is certainly not the most efficient code (quite the opposite), but it works and met the bar of minimum effort for v1.1. Thanks Yuval for insisting and contributing most of the code! After Hebrew support was there, I thought the same solution would work for Arabic. Apparently, reversing the Arabic text is not enough: Arabic characters render themselves differently dependent on what preceded/succeeds them(!). So I needed some kind of utility that takes a reversed Arabic string and returns the same string but with the relevant characters "fixed". Luckily, another MS colleague has put out such a library (thanks Bashar): http://arabic4wp7.codeplex.com/. RTL Solution So you have a reversed RTL string and want to make it "right" before displaying on the screen. This is what worked for me (ymmv). Need to split the string into "lines". Not doing this and just reversing the string and sticking it a wrapping text control means that the user not only has to read right to left, they also have to read bottom up. The previous step must take into account a line length that works for both portrait and landscape modes, and of course, not break words in the middle, i.e. find natural breaks. For each line, break it up into words and reverse the order of the words and the order of the letters within each word On the previous step, do not reverse words that should be preserved, e.g. Windows and other such English words that are mixed in with the Arabic or Hebrew words. The same exclusion from reversal applies to numbers. Specifically, for Arabic, once there is a word that is reversed also change its characters. For some code paths, the above has to take into account whether the translation is "from" an RTL language or if it is "to" an RTL language. I packaged the solution in a single code file containing a static class (see the 'Background" section above for… background and credits). Download RTL.cs for your Windows Phone app (to see its usage in action download for FREE "The best translator app") Enjoy, and if you decide to improve on the code, feel free to share back with me… Comments about this post welcome at the original blog.

  • How can I view the binary contents of a file natively in Windows 7? (Is it possible.)

    - by Shannon Severance
    I have a file, a little bigger than 500MB, that is causing some problems. I believe the issue is in the end of line (EOL) convention used. I would like to look at the file in its uninterpreted raw form (1) to confirm the EOL convention of the file. How can I view the "binary" of a file using something built in to Windows 7? I would prefer to avoid having to download anything additional. (1) My coworker and I opened the file in text editors, and they show the lines as one would expect. But both text editors will open files with different EOL conventions and interpret them automagically. (TextEdit and Emacs 24.2. For Emacs I had created a second file with just the first 4K bytes using head -c4096 on a linux box and opened that from my windows box. I attempted to use hexl-mode in Emacs, but when I went to hexl-mode and back to text-mode, the contents of the buffer had changed, adding a visible ^M to the end of each line, so I'm not trusting that at the moment. I believe the issue may be in the end of line character(s) used. The editors my coworker and I tried (1) just automagically recognized the end of line convention and showed us lines. And based on other evidence I believe the EOL convention is carriage return only. (2) return only. are able to recognize and To know what is actually in the file, I would like to look at the binary contents of the file, or at least a couple thousand bytes of the file, preferablely in Hex, though I could work with decimal or octal. Just ones an zeros would be pretty rough to look at.

  • [Programming General] Advantages of using software framework

    - by ignatius
    Hello, I was reading these days about large projects implementation in python and Flex, and very often people praise the use of framework (like Cairngorm, PureMVC or others) over traditional OOP coding. I think i dont really understand the advantage of using FW, which is the strong point over classic programming? how big should be the project in order to use FW? it is intended mainly for web-applications? or can be used for desktop apps as well? hope, all these doubts dont sound stupid to you, i am not Computer engineer, just electronic, so my knowledge of sw architecture is very limited.

  • How to Export Multiple Contacts in Outlook 2013 to Multiple vCards or a Single vCard

    - by Lori Kaufman
    We’ve shown you how to export a contact to and import a contact from a vCard (.vcf) file. However, what if you want to export multiple contacts at the same time to multiple vCard files or even a single vCard file? Outlook doesn’t allow you to directly export all your contacts as vCard files or as a single vCard file, but there is a way to accomplish both tasks. Export Multiple Contacts to Multiple vCard Files Outlook allows you to forward contact information as a vCard. You can also select multiple contacts and forward them all at once. This feature allows you to indirectly export multiple contacts at once to multiple vCard files. Click the People tab to access your contacts. Select all the contacts you want to export using the Shift and Ctrl keys as needed. Select Contacts the same way you would select files in Windows Explorer. Click Forward Contact in the Share section on the Home tab and select As a Business Card from the drop-down menu. The selected contacts attached to a new email message as .vcf files. To select all the attached .vcf files, right-click in the Attached box and select Select All from the popup menu. Make sure the folder to which you want to export the contacts is open in Windows Explorer. Drag the selected attached .vcf files from the new email message to the open folder in Windows Explorer. A .vcf file is created for each contact you selected and dragged to the folder. You can close the Message window by clicking on the X in the upper, right corner of the window. NOTE: You can also close the Message window by clicking the File tab. Then, click the Close option on the left. Because you already have your .vcf files, you don’t need to save or send the message, so click No when asked if you want to save your changes. If it turns out that a draft of your message was saved, the following message displays. Click No to delete the draft. Export Multiple Contacts to a Single vCard (.vcf) File If you would rather export your contacts to a single vCard (.vcf) File, there is a way to do this using Gmail. We’ll export the contacts from Outlook as a .csv file and then use Gmail to convert the .csv file to a .vcf file. Select the contacts you want to export on the People page and click the File tab. On the Account Information screen, click Open & Export in the list on the left. On the Open screen, click Import/Export. The Import and Export Wizard displays. Select Export to a file from the Choose an action to perform list and click Next. In the Create a file of type box, select Comma Separated Values. Click Next. Contacts should be already selected in the Select folder to export from box. If not, select it. Click Next. Click Browse to the right of the Save exported file as box. Navigate to the folder to which you want to export the .csv file. Enter a name for the file in the File name edit box, keeping the .csv extension. The path you selected is entered into the Save exported file as edit box. Click Next. The final screen of the Export to a File dialog box displays listing the action to be performed. Click Finish to begin the export process. Once the export process is finished, you will see the .csv file in the folder in Windows Explorer. Now, we will import the .csv file into Gmail. Go to Gmail and sign in to your account. Click Gmal in the upper, left corner of the main page and select Contacts from the drop-down menu. On the Contacts page, click More above your list of contacts and select Import from the drop-down menu. Click Browse on the Import contacts dialog box that displays. Navigate to the folder in which you saved the .csv file and select the file. Click Open. Click Import on the Import contacts dialog box. A screen displays listing the contacts you imported, but not yet merged into your main Gmail contacts list. Select the contacts you imported. NOTE: The contacts you imported may be the only contacts in this list. If that’s the case, they all should be automatically selected. Click More and select Export from the drop-down menu. On the Export contacts dialog box, select Selected contacts to indicate which contacts you want to export. NOTE: We could have selected The group Imported 10/10/13 because that contains the same two contacts as the Selected contacts. Select vCard format for the export format. Click Export. Gmail creates a contacts.vcf file containing the selected contacts and asks you whether you want to open the file with Outlook or save the file. To save the file, select the Save File option and click OK. Navigate to the folder in which you want to save the contacts.vcf file, change the name of the file in the File name edit box, if desired, and click Save. The .vcf file is saved to the selected directory and contains all the contacts you exported from Outlook. This could be used as a way to backup your contacts in one file. You could also backup the .csv file. However, if you have a lot of contacts you will probably find that the .vcf file is smaller. We only exported two contacts, and our .csv file was 2 KB, while the .vcf file was 1 KB. We will be showing you how to import multiple contacts from a single .vcf file into Outlook soon.

  • Unix RPC programming

    - by Abhi
    Heyy all, I needed some help with ONC RPC programming. My task is to create two-tier client-server architecture wherein one main server (something like a directory) keeps a track of level-two servers and acts as a lookup; the level-two servers exposing some trivial functions, and finally, the clients for level-two servers. The clients ask the directory where a server is located, and then communicate with it. Using RPCGEN, we can create a pair of client-server code; however, the clients in this case need to have stubs for the directory as well as the level-two functions. Being a newbie to RPC, I'm having trouble conceptualizing the way I should code this. How can I call a function from a different server if a client is generated using a different IDL ? Any pointers would be appreciated :) Regards, Abhi

  • Laws of Computer Science and Programming

    - by Jonas
    We have Amdahl's law that basically states that if your program is 10% sequential you can get a maximum 10x performance boost by parallelizing your application. Another one is Wadler's law which states that In any language design, the total time spent discussing a feature in this list is proportional to two raised to the power of its position. 0. Semantics 1. Syntax 2. Lexical syntax 3. Lexical syntax of comments My question is this: What are the most important (or at least significant / funny but true / sad but true) laws of Computer Science and programming? I want named laws, and not random theorems, So an answer should look something like Surname's (law|theorem|conjecture|corollary...) Please state the law in your answer, and not only a link. Edit: The name of the law does not need to contain it's inventors surname. But I do want to know who stated (and perhaps proved) the law

  • How to backup iTunes on Windows to folder/share, i.e. without "Back Up to Disc"? No DVD writer avail

    - by Chris W. Rea
    (Surprised I didn't already find an answer here to this!) I've got a computer on which I'd like to back up the iTunes library – music, movies, apps, everything. We're talking multiple gigabytes. Unfortunately, it seems that iTunes' own built-in "Back Up to Disc" feature (the only backup feature I can find in iTunes) only functions with a CD or DVD writer/burner. The computer in question does not have a DVD burner. While it has a CD burner, attempting to back up to CDs would require dozens of discs plus more time than I'm willing to spend swapping them. So: What is the recommended way to back up an entire iTunes library on a Windows computer, to a non-CD/DVD location such as an external hard drive or a network shared folder? Then, once such a backup has been performed, what is the process for restoring the library – e.g. after the computer has been repaved with a new version of Windows – so that iTunes is resurrected whole and recognizes devices it syncs with? Thank you!

  • C++ Primer (Stanley Lipmann) or The C++ programming language (special edition)

    - by Kim
    I have a Computer Science degree (long2 time ago) .. I do know Java OOP but i am now trying to pick up C++. I do have C and of course data structure using C or pascal. I have started reading Bjarne Stroustrup book (The C++ Programming Language - Special Edition) but find it extremely difficult esp. some section which i don't have exposure such as Recursive Descent Parser (chapter 6). In terms of the language i don't foresee i have problem but i have problem as mentioned cos' those topic are usually covered in a Master Degree program such as construction of compiler. I just bought a book called C++ primer (Stanley Lipmann) which i heard it is a very good book for C++. Only setback is it's of course no match with the amount of information from the original C++ creator. Please advice. Thanks.

  • Programming tests: are they relevant?

    - by BlackVoid
    Do online programming tests have any value (except for providing an evidence to potential employers) in terms of evaluating your knowledge, or a they too broad or too narrow in general? For examples, brainbench.com and similar websites. From my experience I have never found myself scoring particularly high, although I have many years of commercial experience and is doing great at work. These tests mostly refer to things I have never worked with (WebForms or ADO .Net, who works with ADO .Net directly anyway?), yet these tests claim to be C# tests. If you were hiring a programmer, would you consider online tests as an evidence of real skill?

  • New functional languages

    - by AnnaR
    Functional programming has been around since at least 1958 (creation of Lisp), but is experiencing a renaissance now with old functional languages being dusted off and new functional languages being created. Which functional languages are there that are newly developed or are in the making? I realize that you can write purely functional programs in most high level languages, so with functional languages I imply languages that are specifically designed for functional programming such as F#. If you have links to tutorials, wikis or code examples I encourage you to add them to your answer!
