  • Releasing an open source project without getting embarrassed

    - by Hopeful
    I've been working by myself on a fairly large open source project for quite a while and it's nearing the point where I'd like to release it. However, I'm self-taught and I don't really know anyone who could adequately review my project. A few years ago, I had released a small bit of code which pretty much got ripped apart (in a critical sense) on the forum where I released it. Even though the code worked, the criticism was accurate but brutal. It prompted me to begin searching for best practices for everything and in the end I feel that it made me a much better developer. I've gone over everything in my project so many times trying to make it perfect that I've lost count. I believe in my project and think it has the potential to help a lot of people and I feel like I've done some cool things in interesting ways with it. Still, because I'm self-taught, I can't help but wonder what gaps exist in my self-education. The way my code was ripped apart last time isn't something I'd like to repeat. I think my two biggest fears with releasing my project that I've poured countless hours into are being absolutely embarrassed because I missed some patently obvious things because of my self-education or, worse, releasing it to the sound of crickets. Is there anyone who has been in a similar situation? I'm not afraid of constructive criticism, so long as it is constructive and not just a rant on how I screwed up. I know there is a code review site on StackExchange, but it's not really set up for large projects and I didn't feel like the community there is large enough yet to get good feedback if I were to post parts of my project piecemeal (I tried with one file). What can I do to give my project at least some measure of success without getting embarrassed or devestated in the process?

  • How do I get media players to play ripped dvd files using Handbrake?

    - by LibraryGeekAdam
    I want to rip my dvd collection to put on a server for my tv. I started this with trying 4 dvds using Handbrake. The first 3 ripped perfectly fine according to the directions I used from LifeHacker (http://lifehacker.com/5773000/how-to-rip-dvds-with-handbrake). The 4th dvd took about 2 secs to rip and then stopped saying it was complete. It was not. Now with the 3 files I have I tried to open and play with VLC and Miro. Neither one would play the file. It says its open but there is no sound or video and it doesn't actually show the movie playing in the progress bar. I ran it from the terminal and this is the error message I get. [0xb04c2f38] mp4 demux error: MP4 plugin discarded (no moov,foov,moof box) [mov,mp4,m4a,3gp,3g2,mj2 @ 0xa032980] moov atom not found [mov,mp4,m4a,3gp,3g2,mj2 @ 0xb0efd500] moov atom not found [0xb04c2f38] avformat demux error: Could not open ????e/boris/Videos/Movies/Taras Bulba 1962.m4v: Unknown error 1094995529 I have also changed a file name to end .mp4 instead of .m4v which is how I originally ripped them.

  • What You Said: How You Track Your Time

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your favorite time tracking tips, tricks, and tools. Now we’re back to highlight the techniques HTG readers use to keep tabs on their time. While more than one of you expressed confusion over the idea of tracking how you spend all your time, many of you were more than happy to share the reasons for and the methods you use to stay on top of your time expenditures. Scott uses a fluid and flexible project management tool: I use kanbanflow.com, with two boards to manage task prioritisation and backlog. One board called ‘Current Work’ has three columns ‘Do Today’, ‘In Progress’ and ‘Done’. The other is called ‘Backlog’, which splits tasks into priority groups – ‘Distractions (NU+NI)’, ‘Goals (NU+I)’, ‘Interruptions (U+NI)’, ‘Interruptions (U+NI)’ and ‘Critical (U+I)’, where U is Urgent and I is Important (and N is Not). At the end of each day, I move things from my Backlog to my ‘Current Work’ board, with the idea to keep complete Goals before they become Critical. That way I can focus on ‘Current Work’ Do Today so I don’t feel overwhelmed and can plan my day. As priorities change or interruptions pop up, it’s just a matter of moving tasks between boards. I have both tabs open in my browser all day – this is probably good for knowledge workers strapped to their desk, not so good for those in meetings all day. In that case, go with the calendar on your phone. While the above description might make it sound really technical, we took the cloud-based app for a spin and found the interface to be very flexible and easy to use.

  • Style bits vs. Separate bool's

    - by peterchen
    My main platform (WinAPI) still heavily uses bits for control styles etc. (example). When introducing custom controls, I'm permanently wondering whether to follow that style or rather use individual bool's. Let's pit them against each other: enum EMyCtrlStyles { mcsUseFileIcon = 1, mcsTruncateFileName = 2, mcsUseShellContextMenu = 4, }; void SetStyle(DWORD mcsStyle); void ModifyStyle(DWORD mcsRemove, DWORD mcsAdd); DWORD GetStyle() const; ... ctrl.SetStyle(mcsUseFileIcon | mcsUseShellContextMenu); vs. CMyCtrl & SetUseFileIcon(bool enable = true); bool GetUseFileIcon() const; CMyCtrl & SetTruncteFileName(bool enable = true); bool GetTruncteFileName() const; CMyCtrl & SetUseShellContextMenu(bool enable = true); bool GetUseShellContextMenu() const; ctrl.SetUseFileIcon().SetUseShellContextMenu(); As I see it, Pro Style Bits Consistent with platform less library code (without gaining complexity), less places to modify for adding a new style less caller code (without losing notable readability) easier to use in some scenarios (e.g. remembering / transferring settings) Binary API remains stable if new style bits are introduced Now, the first and the last are minor in most cases. Pro Individual booleans Intellisense and refactoring tools reduce the "less typing" effort Single Purpose Entities more literate code (as in "flows more like a sentence") No change of paradim for non-bool properties These sound more modern, but also "soft" advantages. I must admit the "platform consistency" is much more enticing than I could justify, the less code without losing much quality is a nice bonus. 1. What do you prefer? Subjectively, for writing the library, or for writing client code? 2. Any (semi-) objective statements, studies, etc.?

  • I want to build a Virtual Machine, are there any good references?

    - by Michael Stum
    I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

  • Free RAM disappears - Memory leak?

    - by Izzy
    On a fresh started system, free reports about 1.5G used RAM (8G RAM alltogether, Ubuntu 12.04 with lightdm and plasma desktop, one konsole window started). Having the apps running I use, it still consumes not more than 2G. However, having the system running for a couple of days, more and more of my free RAM disappears -- without showing up in the list of used apps: while smem --pie=name reports less than 20% used (and 80% being available), everything else says differently. free -m for example reports on about day 7: total used free shared buffers cached Mem: 7459 7013 446 0 178 997 -/+ buffers/cache: 5836 1623 Swap: 9536 296 9240 (so you can see, it's not the buffers or the cache). Today this finally ended with the system crashing completely: the windows manager being gone, apps "hanging in the air" (frameless) -- and a popup notifying me about "too many open files". Syslog reports: kernel: [856738.020829] VFS: file-max limit 752838 reached So I closed those applications I was able to close, and killed X using Ctrl-Alt-backspace. X tried to come up again after that with failsafeX, but was unable to do so as it could no longer detect its configuration. So I switched to a console using Ctrl-Alt-F2, captured all information I could think of (vmstat, free, smem, proc/meminfo, lsof, ps aux), and finally rebooted. X again came up with failsafeX; this time I told it to "recover from my backed-up configuration", then switched to a console and successfully used startx to bring up the graphical environment. I have no real clue to what is causing this issue -- though it must have to do either with X itself, or with some user processes running on X -- as after killing X, free -m output looked like this: total used free shared buffers cached Mem: 7459 2677 4781 0 62 419 -/+ buffers/cache: 2195 5263 Swap: 9536 59 9477 (~3.5GB being freed) -- to compare with the output after a fresh start: total used free shared buffers cached Mem: 7459 1483 5975 0 63 730 -/+ buffers/cache: 689 6769 Swap: 9536 0 9536 Two more helpful outputs are provided by memstat -u. Shortly before the crash: User Count Swap USS PSS RSS mail 1 0 200 207 616 whoopsie 1 764 740 817 2300 colord 1 3200 836 894 2156 root 62 70404 352996 382260 569920 izzy 80 177508 1465416 1519266 1851840 After having X killed: User Count Swap USS PSS RSS mail 1 0 184 188 356 izzy 1 1400 708 739 1080 whoopsie 1 848 668 826 1772 colord 1 3204 804 888 1728 root 62 54876 131708 149950 267860 And after a restart, back in X: User Count Swap USS PSS RSS mail 1 0 212 217 628 whoopsie 1 0 1536 1880 5096 colord 1 0 3740 4217 7936 root 54 0 148668 180911 345132 izzy 47 0 370928 437562 915056 Edit: Just added two graphs from my monitoring system. Interesting to see: everytime when there's a "jump" in memory consumption, CPU peaks as well. Just found this right now -- and it reminds me of another indicator pointing to X itself: Often when returning to my machine and unlocking the screen, I found something doing heavvy work on my CPU. Checking with top, it always turned out to be /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none. So after this long explanation, finally my questions: What could be the possible causes? How can I better identify involved processes/applications? What steps could be taken to avoid this behaviour -- short from rebooting the machine all X days? I was running 8.04 (Hardy) for about 5 years on my old machine, never having experienced the like (always more than 100 days uptime, before rebooting for e.g. kernel updates). This now is a complete new machine with a fresh install of 8.04. In case it matters, some specs: AMD A4-3400 APU with Radeon(tm) HD Graphics, using the open-source ati/radeon driver (so no fglrx installed), 8GB RAM, WDC WD1002FAEX-0 hdd (1TB), Asus F1A75-V Evo mainboard. Ubuntu 12.04 64-bit with KDE4/Plasma. Apps usually open more or less permanently include Evolution, Firefox, konsole (with Midnight Commander running inside, about 4 tabs), and LibreOffice -- plus occasionally Calibre, Gimp and Moneyplex (banking software I'm already using for almost 20 years now, in a version which did fine on Hardy).

  • Math questions at a programmer interview?

    - by anon
    So I went to an interview at Samsung here in Dallas, Texas. The way the recruiter described the job, he didn't make it sound like it was too math-oriented. The job basically involved graphics programming and C++. Yes, math is implied in graphics programming, especially shaders, but I still wasn't expecting this... The whole interview lasted about an hour and a half and they asked me nothing but math-related questions. They didn't ask me a single programming question, which I found odd. About all they did was ask me how to write certain math routines as a C++ function, but that's about it. What about programming philosophy questions? Design patterns? Code-correctness? Constness? Exception safety? Thread safety? There are a zillion topics that they could have covered. But they didn't. The main concern I have is that they didn't ask any programming questions. This basically implies to me that any programmer who is good at math can get a job here, but they might put out terrible code. Of course, I think I bombed the interview because I haven't used any sort of linear algebra in about a year and I forget math easily if I haven't used it in practice for a while. Are any of my other fellow programmers out there this way? I'm a game programmer too, so this seems especially odd. The more I learn, the more old knowledge that gets "popped" out of my "stack" (memory). My question is: Does this interview seem suspicious? Is this a typical interview that large corporations have? During the interview they told me that Google's interview process is similar. They have multiple, consecutive interviews where the math problems get more advanced.

  • How do I handle having too many links on a webpage because of my menu

    - by RandomBen
    I am developing a website that has a drop-down menu at the top of it. The Menu has around 100 links in it that are repeated on every page. Every page also has some number of links below the Menu that may or may not be in the menu itself. My issue is that Google says they generally don't like pages with more than 100 links on them. Is there any way to change the links on the menu so that they no longer "count" towards my max of 100 links? It seems like there should be an easy way to do this but their really doesn't seem to be. the rel=nofollow still counts towards the number of links on the page at least according to Google, so what other options do I have? I looked into where the 100 comes from and I found that it used to be here: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=35769#2 but that is no longer the case. I found a more definitive and frankly muddier answer here: http://www.seomoz.org/blog/questions-answers-with-googles-spam-guru from Matt Cutts from 2007. Long story short, in 2007 they still felt 100 links was a good number but they stated you could go far beyond that. In fact, they said that pages with high PageRank could have 2-300. It did sound like having many links could reduce the PageRank of the page with all of the links or possibly all of the items linked to. Also, I know IIS7's SEO 1.0 toolkit suggests that pages should have no more than 250 links.

  • How do I boot into console mode (redux)

    - by Leo Simon
    I'm running Ubuntu 12.04. This question was asked some time ago How do I disable the boot splash screen? but the answers didn't work for me. The standard way to boot into console mode used to be to edit /etc/default/grub and set GRUB_CMDLINE_LINUX_DEFAULT="text" This worked fine until I ran the fix proposed in https://help.ubuntu.com/community/SoundTroubleshootingProcedure in order to get sound to work. Since then, I have disabled the boot-splash-screen, but I can avoid what I presume is the lightdm login prompt screen. All I want to do is disable this gui and be prompted with a console login prompt. (Shouldnt be so hard should it???) I read in three 33416 mentioned above that there was a bug in lightdm (it wasn't recognizing "text" properly as an option for GRUB_CMDLINE_LINUX_DEFAULT.) But this discussion happened more than a year ago, and it's surely been fixed. Yet my lightdm is uptodate (so I'm told when I try to update it with apt-get). As suggested in one of the above, I tried sudo update-rc.d -f lightdm remove which resulted in a hung machine. I managed to recover using recovery mode, but now I still get the gui again. Another suggestion is to edit /etc/init/lightdm.override. I've done this and set it to "manual" as suggested, but lightdm simply ignores this. Could somebody suggest how to proceed please? Thanks very much, Leo

  • Mass Metadata Updates with Folders

    - by Kyle Hatlestad
    With the release of WebCenter Content PS5, a new folder architecture called 'Framework Folders' was introduced.  This is meant to replace the folder architecture of 'Folders_g'.  While the concepts of a folder structure and access to those folders through Desktop Integration Suite remain the same, the underlying architecture of the component has been completely rewritten.  One of the main goals of the new folders is to scale better at large volumes and remove the limitations of 1000 content items or sub-folders within a folder.  Along with the new architecture, it has a new look and a few additional features have been added.  One of those features are Query Folders.  These are folders that are populated simply by a query rather then literally putting items within the folders.  This is something that the Library has provided, but it always took an administrator to define them through the Web Layout Editor.  Now users can quickly define query folders anywhere within the standard folder hierarchy.   Within this new Framework Folders is the very handy ability to do metadata updates.  It's similar to the Propagate feature in Folders_g, but there are some key differences that make this very flexible and much more powerful. It's used within regular folders and Query Folders.  So the content you're updating doesn't all have to be in the same folder...or a folder at all.   The user decides what metadata to propagate.  In Folders_g, the system administrator controls which fields will be propagated using a single administration page.  In Framework Folders, the user decides at that time which fields they want to update. You set the value you want on the propagation screen.  In Folders_g, it used the metadata defined on the parent folder to propagate.  With Framework Folders, you supply the new metadata value when you select the fields you want to update.  It does not have to be defined on the parent folder. Because of these differences, I think the new propagate method is much more useful.  Instead of always having to rely on Archiver or a custom spreadsheet, you can quickly do mass metadata updates right within folders.   Here are the basic steps to perform propagation. First create a folder for the propagation.  You can use a regular folder, but a Query Folder will work as well. Go into the folder to get the results.   In the Edit menu, select 'Propagate'. Select the check-box next to the field to update and enter the new value  Click the Propagate button. Once complete, a dialog will appear showing it is complete What's also nice is that the process happens asynchronously in the background which means you can browse to other pages and do other things while it is still working.  You aren't stuck on the page waiting for it to complete.  In addition, you can add a configuration flag to the server to turn on a status indicator icon.  Set 'FldEnableInProcessIndicator=1' and it will show a working icon as its doing the propagation. There is a caveat when using the propagation on a Query Folder.   While a propagation on a regular folder will update all of the items within that folder, a Query Folder propagation will only update the first 50 items.  So you may need to run it multiple times depending on the size...and have the query exclude the items as they get updated. One extra note...Framework Folders is offered as the default folder architecture in the PS5 release of WebCenter Content.  But if you are using WebCenter Content integrated with another product that makes use of folders (WebCenter Portal/Spaces, Fusion Applications, Primavera, etc), you'll need to continue using Folders_g until they are updated to use the new folders.

  • How to create per-vertex normals when reusing vertex data?

    - by Chris Smith
    I am displaying a cube using a vertex buffer object (gl.ELEMENT_ARRAY_BUFFER). This allows me to specify vertex indicies, rather than having duplicate vertexes. In the case of displaying a simple cube, this means I only need to have eight vertices total. Opposed to needing three vertices per triangle, times two triangles per face, times six faces. Sound correct so far? My question is, how do I now deal with vertex attribute data such as color, texture coordinates, and normals when reusing vertices using the vertex buffer object? If I am reusing the same vertex data in my indexed vertex buffer, how can I differentiate when vertex X is used as part of the cube's front face versus the cube's left face? In both cases I would like the surface normal and texture coordinates to be different. I understand I could average the surface normal, however I would like to render a cube. Also, this still doesn't work for texture coordinates. Is there a way to save memory using a vertex buffer object while being able to provide different vertex attribute data based on context? (Per-triangle would be idea.) Or should I just duplicate each vertex for each context in which it gets rendered. (So there is a one-to-one mapping between vertex, normal, color, etc.) Note: I'm using OpenGL ES.

  • Steam (via Wine) crashes after login - any troubleshooting tips?

I then see the Steam main page and news page displayed for roughly a second or so before the client crashes.

  • How do I properly use String literals for loading content?

    - by Dave Voyles
    I've been using verbatim string literals for some time now, and never quite thought about using a regular string literal until I started to come across them in Microsoft provided XNA samples. With that said, I'm trying to implement a new AudioManager class from the Net Rumble sample. I have two (2) issues here: Question 1: In my code for my GameplayScreen screen I have a folder location written as the following, and it works fine: menuButton = content.Load<SoundEffect>(@"sfx/menuButton"); menuClose = content.Load<SoundEffect>(@"sfx/menuClose"); If you notice, you'll see that I'm using a verbatim string, with a forward slash "/". In the AudioManager class, they use a regular string literal, but with two backslashes "\". I understand that one is used as an escape, but why are they BACK instead of FORWARD? (See below) soundList[soundName] = game.Content.Load<SoundEffect>("audio\\wav\\"+ soundName); Question 2: I seem to be doing everything correctly in my AudioManager class, but I'm not sure of what this line means: audioFileList = audioFolder.GetFiles("*.xnb"); I suppose that the *xnb means look for everything BUT files that end in *xnb? I can't figure out what I'm doing wrong with my file locations, as the sound effects are not playing. My code is not much different from what I've linked to above. private AudioManager(Game game, DirectoryInfo audioDirectory) : base(game) { try { audioFolder = audioDirectory; audioFileList = audioFolder.GetFiles("*.mp3"); soundList = new Dictionary<string, SoundEffect>(); for (int i = 0; i < audioFileList.Length; i++) { string soundName = Path.GetFileNameWithoutExtension(audioFileList[i].Name); soundList[soundName] = game.Content.Load<SoundEffect>(@"sfx\" + soundName); soundList[soundName].Name = soundName; } // Plays this track while the GameplayScreen is active soundtrack = game.Content.Load<Song>("boomer"); } catch (NoAudioHardwareException) { // silently fall back to silence } }

  • When and why you should use void (instead of i.e. bool/int)

    - by Jonas
    I occasionally run into methods where a developer chose to return something which isn't critical to the function. I mean, when looking at the code, it apparently works just as nice as a void and after a moment of thought, I ask "Why?" Does this sound familiar? Sometimes I would agree that most often it is better to return something like a bool or int, rather then just do a void. I'm not sure though, in the big picture, about the pros and cons. Depending on situation, returning an int can make the caller aware of the amount of rows or objects affected by the method (e.g., 5 records saved to MSSQL). If a method like "InsertSomething" returns a boolean, I can have the method designed to return true if success, else false. The caller can choose to act or not on that information. On the other hand, May it lead to a less clear purpose of a method call? Bad coding often forces me to double-check the method content. If it returns something, it tells you that the method is of a type you have to do something with the returned result. Another issue would be, if the method implementation is unknown to you, what did the developer decide to return that isn't function critical? Of course you can comment it. The return value has to be processed, when the processing could be ended at the closing bracket of method. What happens under the hood? Did the called method get false because of a thrown error? Or did it return false due to the evaluated result? What are your experiences with this? How would you act on this?

  • What naughty ways are there of driving traffic?

    - by Tom Wright
    OK, so this is purely for my intellectual curiosity and I'm not interested in illegal methods (no botnets please). But say, for instance, that some organisation incentivised link sharing in a bid to drive publicity. How could I drive traffic to my link? Obviously I could spam all my friends on social networking sites, which is what they want me to do, but that doesn't sound as fun as trying to game the system. (Not that I necessarily dispute the merit of this particular campaign.) The ideas I've come up with so far (in order of increasing deviousness) include: Link-dropping - This is too close to what they want me to do to be devious, but I've done it here (sorry) and I've done it on Twitter. I'm subverting it slightly by focusing on the game aspects rather than their desired message. AdWords - Not very devious at all, but effectively free with the vouchers I've accrued. That said, I must be pretty poor at choosing keywords, because I've seen very few hits (~5) so far. Browser testing websites - The target has a robots txt which prevents browsershots from processing it, but I got around this by including it in an iframe on a page that I hosted. But my creative juices have run dry I'm afraid. Does anyone have any cheeky/devious/cunning/all-of-the-above idea for driving traffic to my page?

  • Is NAN suitable for communicating that an invalid parameter was involved in a calculation?

    - by Arman
    I am currently working on a numerical processing system that will be deployed in a performance-critical environment. It takes inputs in the form of numerical arrays (these use the eigen library, but for the purpose of this question that's perhaps immaterial), and performs some range of numerical computations (matrix products, concatenations, etc.) to produce outputs. All arrays are allocated statically and their sizes are known at compile time. However, some of the inputs may be invalid. In these exceptional cases, we still want the code to be computed and we still want outputs not "polluted" by invalid values to be used. To give an example, let's take the following trivial example (this is pseudo-code): Matrix a = {1, 2, NAN, 4}; // this is the "input" matrix Scalar b = 2; Matrix output = b * a; // this results in {2, 4, NAN, 8} The idea here is that 2, 4 and 8 are usable values, but the NAN should signal to the receipient of the data that that entry was involved in an operation that involved an invalid value, and should be discarded (this will be detected via a std::isfinite(value) check before the value is used). Is this a sound way of communicating and propagating unusable values, given that performance is critical and heap allocation is not an option (and neither are other resource-consuming constructs such as boost::optional or pointers)? Are there better ways of doing this? At this point I'm quite happy with the current setup but I was hoping to get some fresh ideas or productive criticism of the current implementation.

  • Using PowerShell with Office365

    - by Sahil Malik
    SharePoint 2010 Training: more information Did you know, you can fully manage Office365 with PowerShell?What? Wasn’t Office365 supposed to be in the cloud – how do I use powershell with THAT!? Is it black magic? No not really! Office 365 uses the remote powershell functionality of Windows Powershell 2.0. It builds upon the Windows remote management service (you will find it in the services console of Vista+ or Windows2008+ by default, or installed as an addon on XP). It uses that to connect to a web service, and download the available commandlets – based on the logged in user. WHOAA!! So, what can be managed using PowerShell in Office 365? You can manage domains Security Groups Enhanced Authorizations Identity Federation Partner support – where you designate a partner to manage your Office365 And Exchange. Note that Lync and SharePoint online are not manageable via powershell. So, still sound like black magic? What are the actual steps to use Powershell in Office365? Well Read full article ....

    Despite over two decades of GUI interfaces many power users still turn to the command prompt. This week we want to hear about when and how you use the command prompt on your computer. Long ago in a time before you could manipulate your computer with a mouse and a series of buttons and windows, the command line ruled all. Even after years of GUI development and refinement many people still turn to the command line to get things done. This week we want to hear all about your command line tips and tricks. Do you use the default command line for your OS? Have you enhanced it? Replaced it? What keeps you coming back to the command line when everyone happily works away in the OS’s GUI?

  • Ask the Readers: How Do You Deal with Bacn?

    - by Jason Fitzpatrick
    Most people get their fair share of email they want, email they don’t want at all (Spam), and a healthy dose of Bacn–email they want but not right now. How do you deal with your daily dose of Bacn? While Spam is unsolicited garbage you don’t ever want, Bacn is email content you’ve actively selected to receive (weather updates, coupons from your favorite retailers, web site digests, etc.) that isn’t as important as email from friends and coworkers. It’s email that you want but not right now. This week we want to hear all about your methods for wrangling Bacn so you can enjoy it when you’re in the mood but it doesn’t clutter up your inbox when you aren’t. Sound off in the comments with your Bacn handling tips and then check back in on Friday for the What You Said roundup to see how your fellow readers handle things.

  • Where can I find video and audio drivers for my netbook?

    - by Ari
    I got a little netbook yesterday (an Acer Aspire One) for schoolwork and read in numerous reviews Ubuntu was a must. I dove into it blindly and downloaded 12.04 LTS and though I admit it's faster than before, I have no idea how it works yet and was stupid enough to get rid of the Windows 7 Starter that was on there before completely. I can see myself getting used to the rest of Ubuntu, but the main issue is that it seems to have eaten all of my drivers and I don't know where to get any Ubuntu compatible ones. Any video at all is jilty and kind of creepy and any audio is very distorted and REALLY creepy. I understand that this is a tiny $150 typing and light web use school device I'm talking about, but I feel really stupid making the poor thing worse than it was before and not knowing what to do about it. Does anyone know how to install graphics/sound drivers? Or, alternatively, does anyone know where I can get a copy of Windows 7 Starter. I can see myself liking this if the problems are fixable, but if not I still have the product key and would be able to tackle the problem by myself with that.

  • Visual Studio Extensions

    - by Scott Dorman
    Originally posted on: http://geekswithblogs.net/sdorman/archive/2013/10/18/visual-studio-extensions.aspxAs a product, Visual Studio has been around for a long time. In fact, it’s been 18 years since the first Visual Studio product was launched. In that time, there have been some major changes but perhaps the most important (or at least influential) changes for the course of the product have been in the last few years. While we can argue over what was and wasn’t an important change or what has and hasn’t changed, I want to talk about what I think is the single most important change Microsoft has made to Visual Studio. Specifically, I’m referring to the Visual Studio Gallery (first introduced in Visual Studio 2010) and the ability for third-parties to easily write extensions which can add new functionality to Visual Studio or even change existing functionality. I know Visual Studio had this ability before the Gallery existed, but it was expensive (both from a financial and development resource) perspective for a company or individual to write such an extension. The Visual Studio Gallery changed all of that. As of today, there are over 4000 items in the Gallery. Microsoft itself has over 100 items in the Gallery and more are added all of the time. Why is this such an important feature? Simply put, it allows third-parties (companies such as JetBrains, Telerik, Red Gate, Devart, and DevExpress, just to name a few) to provide enhanced developer productivity experiences directly within the product by providing new functionality or changing existing functionality. However, there is an even more important function that it serves. It also allows Microsoft to do the same. By providing extensions which add new functionality or change existing functionality, Microsoft is not only able to rapidly innovate on new features and changes but to also get those changes into the hands of developers world-wide for feedback. The end result is that these extensions become very robust and often end up becoming part of a later product release. An excellent example of this is the new CodeLens feature of Visual Studio 2013. This is, perhaps, the single most important developer productivity enhancement released in the last decade and already has huge potential. As you can see, out of the box CodeLens supports showing you information about references, unit tests and TFS history.   Fortunately, CodeLens is also accessible to Visual Studio extensions, and Microsoft DevLabs has already written such an extension to show code “health.” This extension shows different code metrics to help make sure your code is maintainable. At this point, you may have already asked yourself, “With over 4000 extensions, how do I find ones that are good?” That’s a really good question. Fortunately, the Visual Studio Gallery has a ratings system in place, which definitely helps but that’s still a lot of extensions to look through. To that end, here is my personal list of favorite extensions. This is something I started back when Visual Studio 2010 was first released, but so much has changed since then that I thought it would be good to provide an updated list for Visual Studio 2013. These are extensions that I have installed and use on a regular basis as a developer that I find indispensible. This list is in no particular order. NuGet Package Manager for Visual Studio 2013 Microsoft CodeLens Code Health Indicator Visual Studio Spell Checker Indent Guides Web Essentials 2013 VSCommands for Visual Studio 2013 Productivity Power Tools (right now this is only for Visual Studio 2012, but it should be updated to support Visual Studio 2013.) Everyone has their own set of favorites, so mine is probably not going to match yours. If there is an extension that you really like, feel free to leave me a comment!

  • libgdx game not disposing

    - by Yesh
    My game does not exit entirely even after calling dispose() method. It loads a black screen when I launch it for the second time and works well if I kill the game manually and restart it. I get an error that says buffer not allocated with newUnsafeByteBuffer or already disposed when I try to dispose off the SpriteBatch object. This is were I suspect the problem to be. But not able to fix it entirely. Please help! Here is how I have built it (I have put the sample code here just to show you guys that there are no visible loop backs in dispose function, please correct me if I'm wrong)- In game screen, public void dispose() { AssetLoader.dispose(); render.dispose(); Gdx.app.exit(); } Under class AssetLoader- public void dispose(){ Texture.dispose(); sound.dispose(); } Under game render class - public void dispose(){ spritebatch.dispose(); //throws an error when I GameScreen.dispose is called font.dispose(); shaperender.dispose(); } I believe that my spritebatch isn't disposing which is causing the black screen but I cannot find a way to dispose it off successfully. Any help would be greatly appreciated.

  • Where to find and install ASUS motherboard drivers for Linux

    - by Dan
    This is my second day ever with Linux, and I had one heck of a time getting the nVidia drivers installed and working. Please, keep in mind I am very new and just starting out. I currently have an ASUS P8Z68-V LE motherboard and I'm not sure if the drivers are installed. Where would I go to find that out? I am using Gnome as my UI. If I don't have the drivers installed, where would I go? The ASUS site only gives me options to download for various Windows OS, DOS and "other" (in .ROM format). Which should I take and how should I install? I'm mostly looking for audio drivers. A lot of music I play, either on YouTube or with VLC has a faint crackling in the background on Ubuntu, which gets much worse the higher I turn the volume up. Could this be something other than the drivers? I doubt it's the hardware since the sound seems fine on Windows. I am currently running 12.04.
