• Naming conventions used for variables and functions in C

  - by Zel

  While coding a large project in C I came upon a problem. If I keep on writing more code then there will be a time when it will be difficult for me to organize the code. I mean that the naming for functions and variables for different parts of the program may seem to be mixed up. So I was thinking whether there are useful naming conventions that I can use for C variables and functions? Most languages suggest a naming convention. But for C the only thing I have read so far is the names should be descriptive for code readability. EDIT: Examples of some examples of suggested naming conventions: Python's PEP 8 Java Tutorial I read some more naming conventions for java somewhere but couldn't remember where.

• HTG Explains: How the SmartScreen Filter Works in Windows 8

  - by Chris Hoffman

  Windows 8 includes a SmartScreen filter that prevents unknown and malicious programs from running. SmartScreen is part of Internet Explorer 8 and 9 – with Windows 8, it’s now integrated into the operating system. SmartScreen is a useful security feature that will help prevent bad applications from running, but it may occasionally prevent a legitimate application from running. SmartScreen reports some information to Microsoft, so it may have some privacy implications. HTG Explains: Is ReadyBoost Worth Using?

• Why my site is not ranking for particular keyword

  - by user543087

  My site is only 3 days to be 6 months old. This website is unique, that is there is no competitor to this type site in India, providing comparison of payment gateways in India, besides the payment gateways companies itself. I've optimized it for key word : "payment gateway" I've changed the url's twice, latest being 3 months back, in which case Google Webmaster gave plently of 404's. I corrected the useful 404's and left meaningless ones as it is. What is the reason it's not ranking well for payment gateways? Even site with single page about "Payment gateways" seem to be ranking better than this. Is it does to: 1) Lot of outbound links to in-context companies and information 2) 404's as reported in Google Webmaster My another site is successfully getting 1500 unique visitors daily and is up in Google ranking. I don't know why it is not!

• Why does a computer science degree matter to a professional programmer?

  - by P.Brian.Mackey

  I have a degree in computer science. It has been great for opening doors, getting a job. As far as helping me in the professional field of C# .NET programming (the most popular platform and language in the area I work if not the entire united states on hands down the most popular OS in the world) its hardly useful. Why do you think it helps you as a programmer in your professional career (outside spouting off to prims algorithm to impress some interviewer)? In today's world adaptation, a quick mind, strong communication, OO and fundamental design skills enable a developer to write software that a customer will accept. These skills are only skimmed over in the cs program. In my mind, reading a 500 page C# book by Wrox offers far more useable a skillset than 4 years of the comp sci math blaster courses. Many disagree. So, why does a computer science degree matter?

• Why is there a "new" in Go?

  - by dystroy

  I'm still puzzled as why we have new in Go. When you want to instantiate a struct, you do t := Thing{} and, obviously, you can get a pointer to a new instance by doing t := &Thing{} But there's also this possibility : t := new(Thing) This last one seems a little alien to me. &Thing{} is as clear and concise as new(Thing) and it uses only constructs you often use elsewhere. It's also more extensible as you might change it to &Thing{3} or &Thing{Feets:7}. In my opinion, having a supplementary keyword is costly, it makes the language more complex and adds to what you must know. And it might mask to newcomers what's behind instantiating a struct. It also makes one more reserved word. So what's the reasoning behind new ? Is it something useful ? Should we use it ?

• What is the best C++ interview question?

  - by David Thielen

  If you could ask a C++ programmer one question to measure their C++ skills, what would it be? The question I think is best is: Can you call "delete this;" inside a member function? (I put this as a link so you can think it through first, then go to The Best C++ Interview Question – Ever! to see the correct answer.) I don't ask this because I expect most people to know the answer. If they did it would not be that useful a question. I ask to see if they can work their way to the correct answer and how they do so.

• Where to start studying for developing ubuntu?

  - by Mad-scientist

  Hi am Computer Science student currently in college and very interested in developing open source software especially ubuntu.Is there a one stop go-to place for reading about developing ubuntu. For example I scoured through the official tutorial and documentation of Python and I was good to go.I could write useful applications. Is there any equivalent for Ubuntu or unity? I tried downloading the alpha 2,put kept crashing every 5 minute. I was told in IRC,it was due to some Xorg stack change. Now I cant even look at new Unity,let alone help develop it. Any help or guidance appreciated.

• New Solaris 11 Customer Maintenance Lifecycle blog

  - by user12244672

  Hi Folks, On the basis that you can't have too much of a good thing, I've started a 2nd blog, the Solaris11Life blog , to enable me to blog about all aspects of the Solaris 11 Customer Maintenance Lifecycle, including policies, best practices, resource links, clarifications, and anything else which I hope you may find useful. In my first post, I share my Solaris 11 Customer Maintenance Lifecycle presentation, which I gave at Oracle Open World and the recent Deutsche Oracle Anwendergruppe (DOAG) conference. I'll be posting lots more there in the coming week as time allows, including secret handshake stuff on how to interpret IPS FMRI version strings. In future, I'll post any Solaris 11 Customer Maintenance Lifecycle related material on the Solaris11Life blog, http://blogs.oracle.com/Solaris11Life , and any Solaris 10 or below material here on the Patch Corner blog, http://blogs.oracle.com/patch . Best Wishes, Gerry.

• SQL Peer-to-Peer Dynamic Structured Data Processing Collaboration

  Unstructured and XML semi-structured data is now used more than structured data. But fixed structured data still keeps businesses running day in and day out, which requires consistent predictable highly principled processing for correct results. For this reason, it would be very useful to have a general purpose SQL peer-to-peer collaboration capability that can utilize highly principled hierarchical data processing and its flexible and advanced structured processing to support dynamically structured data and its dynamic structured processing. This flexible dynamic structured processing can change the structure of the data as necessary for the required processing while preserving the relational and hierarchical data principles. This processing will perform freely across remote unrelated peer locations anytime and transparently process unpredictable and unknown structured data and data type changes automatically for immediate processing using automatic metadata maintenance.

• Learning PHP OOP

  - by Ryan Murphy

  I have been coding PHP for about 2 years now and I THINK that I have a very good grasps of the fundamental parts of PHP, i.e. Functions foreach/IF statements sessions/cookies POST/GET Amongst a few others. I want to move on to learning OOP PHP now, so learning how to use classes and making it a really valuable skill. I have 1 requirement, the source must be a respected source that doesn't teach developers bad habits. I have the book: PHP and MySQL Web Development However, as useful as that is I would like an online source. I would like to know from people with experience in OOP PHP, how and where did they learn OOP PHP. Obviously by doing, but I would really appreciate some great resources which help me along the way.

• Will the Mac app store accept an app that reads and parses iPhone backups?

  - by John Wright

  I wanted to submit an app to the Mac app store that reads the iPhone backup dir and provides some useful functionality on user's voicemails and sms messages. The app parses and reads the backup mbdb files, and extracts the voicemail and sms sqlite db files as well as the voicemails to a temp directory. Is this kind of app likely to be rejected since it reads an unpublished format? It's not using any private APIs. I realize none of you are reviewers but wondering if I should even try to submit it to the store.

• How can I find a good open source project to join?

  - by Lord Torgamus

  I just started working a year ago, and I want to join an open source project for the same reasons as anyone else: help create something useful and develop my skills further. My problem is, I don't know how to find a project where I'll fit in. How can I find a beginner-friendly project? What attributes should I be searching for? What are warning signs that a project might not be the right fit? Are there any tools out there to help match people with open source projects? There's a similar question here, but that question has to do with employment and is limited to PHP/Drupal.

• Does anybody know what happens to money spent in the Ubuntu One Music Store?

  - by Dave

  I remember reading on the Canonical website around the launch of the Ubuntu One Music store that after revenue was divided between Canonical, 7 digital and the artists involved that all profit or a significant percentage would be donated to a charity. This information has either disappeared from their website or my detective skills have failed me once more. Does anybody happen to understand the break down of revenue generated by the Ubuntu One Music Store or even know where to find this information. Also it would be useful to know which charity benefits from this. (Not that that would impact upon my purchases or send me running to iTunes. ;) Promise)

• What do you look for in a scripting language?

  - by Jon Purdy

  I'm writing a little embedded language for another project. While game development was not its original intent, it's starting to look like a good fit, and I figure I'll develop it in that vein at some point. Without revealing any details (to avoid bias), I'm curious to know: What features do you love in a scripting language for game development? If you've used Lua, Python, or another embedded language such as Tcl or Guile as your primary scripting language in a game project, what aspects did you find the most useful? Language features (lambdas, classes, parallelism) Implementation features (performance optimisations, JIT, hardware acceleration) Integration features (C, C++, or .NET bindings) Or something entirely different?

• Verifying Office 2010 SP1 Installation

  - by Chris Heacock

  So you downloaded and installed SP1, but now you want to verify that SP1 actually installed! Looking at Outlook's Help Screen under Help->About, it isn't readily apparent that SP1 is installed. Like me, you probably expected to see 14.1.something. Perhaps 14.0.something SP1, right? If you click on that "Additional Version and Copyright Information", another window will pop up and show you a bit more useful info (if you don't have the version numbers committed to memory) That window *does* give us that comforting SP1, and now we can determine that if you have Office 14.1.6023.1000 (and beyond) you are indeed runnning Office 2010 SP1!

• Self Welcoming Post on geekswithblogs.net

  - by OscarRibbeck

  Hello!.As you may notice :), this is my first post on geekswithblogs.com . I  have been using the .Net Framework mainly to develop ASP.NET WebApps for some years now and I am moving from using the .Net Framework 2.0 to using the latest features on the 4.x Frameworks, I am planning to document whenever is possible some of the stuff I learn using this space kindly given by the staff of the site. The feedback I get will also be very important for my progress and my plan is to learn a lot from what you guys can teach me with your comments on here.I also found myself with the necessity of putting somewhere code samples because sometimes when you post on forums the entries get locked and you can't do anything to add relevant details on them. The code will either be explained on its entirety or will be posted on a link that has an explained working sample for you guys to test and learn from.My posts will be in English, and I am an intermediate English speaker/writer so bare with me if it's not perfect sometimes, I am always learning something new though.I hope this get to be a useful resource for anyone interested. Cheers and Happy Coding for everyone!,Oscar

  I am new at Android game development. I have done some apps before, but none of them are games :) So, I wanted to do a frame-by-frame animation of PNGs. I tried with AnimationDrawable, but OutOfMemory error comes quickly (I have a lot of PNGs). So I came upon SurfaceView. But I am stuck, because I really don't find any useful tutoirals/examples. What is the best way to make an animation like this? Here there already is a great answer to almost the same question, but all the links there don't work anymore. I would really like to here suggestions how to make an animation frame-by-frame with PNGs in Android and if you have any tutorials or examples, I will be really happy :)

• How to set up Google DFP (DoubleClick for Publishers) for a site?

  - by Manoj Kumar

  I have a website and I have an AdSense account as well. I have integrated AdSense and ads are also getting displayed (480 x 60). Somewhere I read that I can manage the ads that are being shown in my website (480 x 60) and filter out the ads on a CPM/CPC basis. NOTE: I don't have any ads to be displayed on other's websites. I just want to show other's ads on my website. Now, can I use Google DFP to manage the ads? I mean is Google DFP useful for me to filter the ads and get me more revenue?

• C# Concisely by Judith Bishop &amp; Nigel Horspool

  - by MarkPearl

  In my quest to read all the books I have lying on my bookshelf I have finally got round to finishing C# Concisely (ISBN 0-321-15418-5). While this book was fairly old, I found it to be quite useful for a student wanting to learn C# for the first time, and a nice way to review and make I hadn’t missed something when I was learning the language. The book is simple and explains the basic concepts in a clean manner, but is really intended for the beginner programmer – it also had a few chapters dedicated to winforms, which was an indication of its age. None the less, I will keep it on the bookshelf so when I come across someone who is wanting to learn the language I can give them it as a gift.

• Nautilus tags/labels/marks/emblems for directories

  - by madox2

  Is there any way how to mark folders or files with tags(or labels or whatever) in Nautilus? It would be nice to sort marked folders or files through this tags. I am familiar with emblems but I cant sort through it and its complicated to assign emblem to folder(3 clicks at least). Especially my first idea was to mark folders in my Movie directory with tags seen, not seen, must see, and so on. Then I realized it would be useful in any other workspace with any custom tags... Is there any nautilus extension for this? Or any other file manager which can do this?

• CLR via C# - first post of many!

  - by TATWORTH

  I am currently reading CLR via C# ISBN 978-0-7356-2704-8. Whilst quite correctly described by the publisher as a "Deep Dive", this is a book that C# developers with 6-18 months plus experiance ought to read. Certainly any serious Microsoft programming shop ought to have a copy.  For our VB.NET bretheren, a book of this quality is a good excuse to learn C#. (And before you ask, my favourite language of C# and VB.NET is the one that gets me the next contract!) When I started programming 31 years ago I went through IBM 360 Orientation - this gave me an comprehension of what worked best at the machine code level - this is the first book I have found that explains the the working of the Dot Net framework to explain why particular choices are good, This is my first blog post here. In the coming weeks, I intend to: Carry on with my review of CLR via C# and bring out practical points from that work. Post details of useful utilities Post some "Tales from the coal face.."

• Profiling Startup Of VS2012 &ndash; YourKit Profiler

  - by Alois Kraus

  The YourKit (v7.0.5) profiler is interesting in terms of price (79€ single place license, 409€ + 1 year support and upgrades) and feature set. You do get a performance and memory profiler in one package for which you normally need also to pay extra from the other vendors. As an interesting side note the profiler UI is written in Java because they do also sell Java profilers with the same feature set. To get all methods of a VS startup you need first to configure it to include System* in the profiled methods and you need to configure * to measure wall clock time. By default it does record only CPU times which allows you to optimize CPU hungry operations. But you will never see a Thread.Sleep(10000) in the profiler blocking the UI in this mode. It can profile as all others processes started from within the profiler but it can also profile the next or all started processes. As usual it can profile in sampling and tracing mode. But since it is a memory profiler as well it does by default also record all object allocations > 1MB. With allocation recording enabled VS2012 did crash but without allocation recording there were no problems. The CPU tab contains the time line of the application and when you click in the graph you the call stacks of all threads at this time. This is really a nice feature. When you select a time region you the CPU Usage estimation for this time window. I have seen many applications consuming 100% CPU only because they did create garbage like crazy. For this is the Garbage Collection tab interesting in conjunction with a time range. This view is like the CPU table only that the CPU graph (green) is missing. All relevant information except for GCs/s is already visible in the CPU tab. Very handy to pinpoint excessive GC or CPU bound issues. The Threads tab does show the thread names and their lifetime. This is useful to see thread interactions or which thread is hottest in terms of CPU consumption. On the CPU tab the call tree does exist in a merged and thread specific view. When you click on a method you get below a list of all called methods. There you can sort for methods with a high own time which are worth optimizing. In the Method List you can select which scope you want to see. Back Traces are the methods which did call you. Callees ist the list of methods called directly or indirectly by your method as a flat list. This is not a call stack but still very useful to see which methods were slow so you can see the “root” cause quite quickly without the need to click trough long call stacks. The last view Merged Calles is a call stacked view of the previous view. This does help a lot to understand did call each method at run time. You would get the same view with a debugger for one call invocation but here you get the full statistics (invocation count) as well. Since YourKit is also a memory profiler you can directly see which objects you have on your managed heap and which objects do hold most of your precious memory. You can in in the Object Explorer view also examine the contents of your objects (strings or whatsoever) to get a better understanding which objects where potentially allocating this stuff.   YourKit is a very easy to use combined memory and performance profiler in one product. The unbeatable single license price makes it very attractive to straightly buy it. Although it is a Java UI it is very responsive and the memory consumption is considerably lower compared to dotTrace and ANTS profiler. What I do really like is to start the YourKit ui and then start the processes I want to profile as usual. There is no need to alter your own application code to be able to inject a profiler into your new started processes. For performance and memory profiling you can simply select the process you want to investigate from the list of started processes. That's the way I like to use profilers. Just get out of the way and let the application run without any special preparations.   Next: Telerik JustTrace

• What C++ libraries can be used in game development [closed]

  - by RedShft

  I'm currently in the planning stage for my next game, and since I've been away from C++ for a while I have some questions about helpful libraries. I plan on making a 2D game with SDL, constructing my own simple 2D engine. I plan on making this game for the PC. What libraries would you recommend to make this process easier? What about unittests? What about an enforce operator to throw exceptions? int a = 1; enforce(a == 2); //Throws an exception, Specifically, i'm looking for general purpose libraries, that implement that make my life easier (like boost). Also, a helpful library for physics/collision, AI, XML file parsing (specifically working with the Tiled map editor), and any others that you guys have used that are useful in a 2D game.
