• SharePoint Saturday DC 2010 Slides, Demo Scripts, and Pictures

  - by Brian Jackett

  Wow! This past weekend I attended SharePoint Saturday Washington DC (SPSDC) which was quite an event to say the least.  For those unfamiliar, SharePoint Saturday is a community driven event where various speakers gather to present at a FREE conference on all topics related to SharePoint.  This made my fifth SharePoint Saturday attended and fourth I’ve spoken at.  SPSDC was a bit different than most SharePoint Saturdays mostly due to the scale of it.  We had almost 950 attendees, over 80 speakers presenting close to 90 sessions, and dozens of sponsors.  A big thanks goes out to the organizers of this event.  They put in a lot of hard work and time to pull this event off and should be very proud of the end result.      For SPSDC I presented “The Power of PowerShell + SharePoint 2007”.  I want to thank all of the attendees of my session for coming and asking some great questions.  Below you can find the slides and demo scripts for this session.  I also took some photos throughout the day (not as many as usual since so much going on) so check them out.  If you have any follow up questions feel free to drop me a line in the comments or the contact link at the top of the site.   Slides and Scripts Click here for the demo scripts and slides posted on my SkyDrive. VERY IMPORTANT NOTE: One thing I forgot to mention in my presentation.  In order to run code against the SharePoint API you need to load the Microsoft.SharePoint.dll assembly first.  Run the below command on the PowerShell console line to complete that:   [void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") Photos Facebook album -or- My album on Windows Live site (higher res shots).

• My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

  - by Dominic Bou-Samra

  So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

• Lessons From OpenId, Cardspace and Facebook Connect

  - by mark.wilcox

  (c) denise carbonell I think Johannes Ernst summarized pretty well what happened in a broad sense in regards to OpenId, Cardspace and Facebook Connect. However, I'm more interested in the lessons we can take away from this. First  - "Apple Lesson" - If user-centric identity is going to happen it's going to require not only technology but also a strong marketing campaign. I'm calling this the "Apple Lesson" because it's very similar to how Apple iPad saw success vs the tablet market. The iPad is not only a very good technology product but it was backed by a very good marketing plan. I know most people do not want to think about marketing here - but the fact is that nobody could really articulate why user-centric identity mattered in a way that the average person cared about. Second - "Facebook Lesson" - Facebook Connect solves a number of interesting problems that is easy for both consumer and service providers. For a consumer it's simple to log-in without any redirects. And while Facebook isn't perfect on privacy - no other major consumer-focused service on the Internet provides as much control about sharing identity information. From a developer perspective it is very easy to implement the SSO and fetch other identity information (if the user has given permission). This could only happen because a major company just decided to make a singular focus to make it happen. Third - "Developers Lesson" -  Facebook Social Graph API is by far the simplest API for accessing identity information which also is another reason why you're seeing such rapid growth in Facebook enabled Websites. By using a combination of URL and Javascript - the power a single HTML page now gives a developer writing Web applications is simply amazing. For example It doesn't get much simpler than this "http://api.facebook.com/mewilcox" for accessing identity. And while I can't yet share too much publicly about the specifics - the social graph API had a profound impact on me in designing our next generation APIs.  Posted via email from Virtual Identity Dialogue

• How will my Electronic Engineering degree be received in the Canadian Game Development market? [closed]

  - by Harikawashi

  I have a Electronic Engineering with Computer Science Degree from a reputable South African university. The EE with CS degree is basically Electronic Engineering, with some of the high voltage subjects thrown out and replaced with computer science subjects - mostly quite theoretical, but not in too much depth. I went on to earn a Masters Degree in Digital Signal Processing, focussing on Speech Recognition in Educational Applications. I have always loved programming - I taught myself QBASIC when I was in primary school, I learned Java at school, did some low level C at University, and taught myself C# and Python while doing my post graduate degree. C# is currently my strong suit, I think I am pretty capable with it. I have two years work experience in Namibia - working as a consulting electrical engineer (no software content whatsoever) and also developing C# desktop applications for the company I work for. I would like to move to Canada next year and work in the Game Development Industry as programmer or software engineer. My interests in particular are towards the more mathematical applications, like game and physics engines, or statistical disciplines like artificial intelligence. However, these are passions - not areas in which I have any work experience. So the question: How well will my BEngEE&CS and MScEng be received in the game industry? Seeing as it's not a pure software degree and I have no official software development work experience?

• The Fantastic New WebLogic on Oracle Database Appliance 2.9 Release is Here!

  - by JuergenKress

  Last week was a big day in virtualised ODA-land as it saw the launch of WebLogic on ODA 2.9. Admittedly it doesn't sound like a very exciting release but it is one that we at O-box have been looking forward to for quite some time. Let me explain why, then we'll look into the details... The ODA X4-2 has 48 Intel Xeon cores. That is a lot of compute power. Whilst the largest O-box SOA Appliance single environment configuration can in theory use all those cores (currently with 40 vCPU of SOA!) the vast majority of O-box users will want smaller configurations. Prior to 2.9 the Oracle WebLogic implementation only supported one domain per ODA, so the conundrum O-box development faced last year was either: offer customers only one SOA environment on their O-box for now (but have the benefit of a standard, easily supportable WebLogic installation), or build our own WebLogic/OTD OVM templates from scratch. One of our driving goals with O-box is to give the best possible experience and make the appliance as supportable as possible. Therefore we took the gamble that we would stick with the Oracle's one-domain WebLogic configuration initially, and just hope that it would deliver multi-domain support for us in a timely manner (note: this is probably not a strategy that business textbooks would recommend!). Anyway, we've been working closely with Oracle Product Management for a few months now and I'm delighted to see 2.9 as the fruits of their labour. This also neatly ties in with several recent requests for O-box to include OSB as well as SOA/BPEL (which we have always wanted to have in separate domains). The diagram below is the neatest way to summarise what the new 2.9 release will allow us to deliver, i.e. previously only one 3D box was possible: Read the complete article here.

• Wake laptop when lid is opened?

  - by crackout12

  I have a SAMSUNG laptop, which by the experience in the last months, has been a great one. I am actually implementing some functionality to it, and since I noticed, I am able to wake up my laptop from sleep by just opening the lid on Windows 7, however, I need to press to power button to wake up in Ubuntu. Using a program called i-nex, I noted that the kernel DOES dettect a "lid switch", and I am looking forward to use it to wake up function. Any ideas? UPDATE: Thanks @yossile for bringing up some clues! However, output of command cat /proc/acpi/wakeup does not show the LID device. I still tried the second set of commands you gave me with no effect. Then I tried experimenting, guessing that LID should be named by other value, so I tried enabling the others. No victory so far. But I noticed that devices that did not have any pci listings were disabled at all time no matter what I tried. Here is the output of command cat /proc/acpi/wakeup: root@samsung:~# cat /proc/acpi/wakeup Device S-state Status Sysfs node PCE4 S4 *disabled pci:0000:00:04.0 SBAZ S4 *disabled pci:0000:00:14.2 P0PC S4 *disabled pci:0000:00:14.4 GEC S4 *disabled PE20 S4 *disabled pci:0000:00:15.0 PE21 S4 *disabled PE22 S4 *disabled pci:0000:00:15.2 PE23 S4 *disabled PWRB S5 *enabled So maybe it could be that LID is either GEC,PE21, or PE23? Still, there is /proc/acpi/button/lid/LID/state file which shows that LID is opened. Any more ideas?

• HP Notebook Pavilion g6-2101sl freeze

  - by StErMi

  I just bought this notebook and I've already installed in a new partition Ubuntu 12.04 LTS with 6gb of swap memory. UPDATE2: This is the laptop configuration: http://h10025.www1.hp.com/ewfrf/wc/document?cc=it&lc=it&dlc=it&tmp_geoLoc=true&docname=c03397517 Sometimes (without any special conditions) Ubuntu freezes. My mouse is blocked, the UI is blocked, ALT+F1 to kill something or to restart is blocked, I can't really do anything... I've also tried and it freezes with: Ubuntu 3D Ubuntu 2D Gnome Shell and it freezes both with low and high load. I can only press on power button (physically) and restart my laptop (and this is not the correct way to do things). I'm using this laptop for work, so I need a stable OS without this freeze. Someone knows how to solve this problem? UPDATE: /var/log/messages is empty /var/log/kernel.log - http://paste.ubuntu.com/1220182/ /var/log/Xorg.0.log - http://paste.ubuntu.com/1220186/ I just installed propetary driver from ATI, it crash anyway. This morning I started laptop, I enabled wireless, opened dropbox and chrome - freeze. When it freeze I cannot: Do ctrl+alt+f1 to get console access AltF2 + r to reload session Alt+Print + RESUB to restart I totally freezed.

• Need Guidance Making HTML5 Canvas Game Engine

  - by Scriptonaut

  So I have some free time this winter break and want to build a simple 2d HTML5 canvas game engine. Mostly a physics engine that will dictate the way objects move and interact(collisions, etc). I made a basic game here: http://caidenhome.com/HTML%205/pong.html and would like to make more, and thought that this would be a good reason to make a simple framework for this stuff. Here are some questions: Does the scripting language have to be Javascript? What about Ruby? I will probably write it with jQuery because of the selecting powers, but I'm curious either way. Are there any great guides you guys know of? I want a fast guide that will help me bust out this engine sometime in the next 2 weeks, hopefully sooner. What are some good conventions I should be aware of? What's the best way to get sound? At the moment I'm using something like this: var audioElement = document.createElement('audio'); audioElement.setAttribute('src', 'paddle_col.wav'); audioElement.load(); I'm interested in making this engine lightweight and extremely efficient, I will do whatever it takes to get great speeds and processing power. I know this question is fairly vague, but I just need a push in the right direction. Thanks :)

• Creating an expandable, cross-platform compatible program "core".

  - by Thomas Clayson

  Hi there. Basically the brief is relatively simple. We need to create a program core. An engine that will power all sorts of programs with a large number of distinct potential applications and deployments. The core will be an analytics and algorithmic processor which will essentially take user-specific input and output scenarios based on the information it gets, whilst recording this information for reporting. It needs to be cross platform compatible. Something that can have platform specific layers put on top which can interface with the core. It also needs to be able to be expandable, for instance, modular with developers being able to write "add-ons" or "extensions" which can alter the function of the end program and can use the core to its full extent. (For instance, a good example of what I'm looking to create is a browser. It has its main core, the web-kit engine, for instance, and then on top of this is has a platform-specific GUI and can also have add-ons and extensions which can change the behavior of the program.) Our problem is that the extensions need to interface directly with the main core and expand/alter that functionality rather than the platform specific "layer". So, given that I have no experience in this whatsoever (I have a PHP background and recently objective-c), where should I start, and is there any knowledge/wisdom you can impart on me please? Thanks for all the help and advice you can give me. :) If you need any more explanation just ask. At the moment its in the very early stages of development, so we're just researching all possible routes of development. Thanks a lot

• Newly installed Ubuntu 12.10 and weird graphics

  - by Benji Marshall

  My machine: 2 GB RAM Intel Pentium Dual core E2180 @ 2 GHz NVIDIA GeForce 6200 LE My friend had recommended Ubuntu to me and I thought I might as well get used to Linux in anticipation for my Raspberry Pi. He said that Wubi was the easiest way to install and I installed it using Wubi. On my first ever boot up of Ubuntu from the Windows Bootloader started normally, and I logged on in a normal fashion, and my desktop loaded normally. I then pressed the Windows key/Power key and everything went wrong. Random lines of yellow and blue appeared on my screen, and changed location when I moved my mouse. The lines stayed for a few seconds and then partially went to I could sort of use my computer. I tried moving my mouse and the entire desktop looked like it broke apart, fragments of it just scatter across my screen at random angles. I could move my mouse and the pointer would move but clicking did nothing. I had to turn off my machine by removing the plug. I would love to get off Windows, but at least the doesn't completely mess up the graphics, and is relatively usable. Please help me solve this....

• MMORPG design for time-limited players

  - by Philipp

  I believe that there is a significant market of players who would enjoy the exploration and interaction aspects of MMORPGs, but simply don't have the time for the endless grinding marathons which are part of the average MMORPG. MMORPGs are all about interaction between players. But when different players have different amounts of time to invest into a game, those with less time to spend will soon lack behind their power-leveling friends and won't be able to interact with them anymore. One way to solve this would be to limit the progress a player can achieve per day, so that it simply doesn't make sense to play more than one or two hours a day. But even the busiest casual players sometimes like to spend a whole sunday afternoon playing a video game. Just stopping them after two hours would be really frustrating. It also creates a pressure to use the daily progress limit every day, because otherwise the player would feel like wasting something. This pressure would be detrimental for casual gamers. What else could be done to level the playing field between those players who play 40+ hours a week and those who can't play more than 10?

• Thick models Vs. Business Logic, Where do you draw the distinction?

  - by TokenMacGuy

  Today I got into a heated debate with another developer at my organization about where and how to add methods to database mapped classes. We use sqlalchemy, and a major part of the existing code base in our database models is little more than a bag of mapped properties with a class name, a nearly mechanical translation from database tables to python objects. In the argument, my position was that that the primary value of using an ORM was that you can attach low level behaviors and algorithms to the mapped classes. Models are classes first, and secondarily persistent (they could be persistent using xml in a filesystem, you don't need to care). His view was that any behavior at all is "business logic", and necessarily belongs anywhere but in the persistent model, which are to be used for database persistence only. I certainly do think that there is a distinction between what is business logic, and should be separated, since it has some isolation from the lower level of how that gets implemented, and domain logic, which I believe is the abstraction provided by the model classes argued about in the previous paragraph, but I'm having a hard time putting my finger on what that is. I have a better sense of what might be the API (which, in our case, is HTTP "ReSTful"), in that users invoke the API with what they want to do, distinct from what they are allowed to do, and how it gets done. tl;dr: What kinds of things can or should go in a method in a mapped class when using an ORM, and what should be left out, to live in another layer of abstraction?

• Alienware M17x R3: Possible downclock

  - by Ywen

  I installed recently Kubuntu 11.10 32 bits (had graphics driver issues, wanted to try on 32 bits version) on my new Alienware M17x, with a Core i7-2670QM CPU. Cores are supposed to be clocked at 2.2 GHz, however the output of $ cat /proc/cpuinfo | grep -i "hz" gives me: model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 model name : Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz cpu MHz : 800.000 If useful, the AC adapter is plugged in (yet the ouput is the same when the computer is powered only by the battery) and I have Firefox and Eclipse running. Does /proc/cpuinfo reflect a possible automatic downclock made to save power if processor load is low or is this output abnormal? EDIT: Ok, I checked and yes, the ouput does vary in function of the load. I reach 2.2 GHz when needed. But my following problem remains. I was checking my CPU clocking because I experienced poor performances when reading 720p video files on Ubuntu with VLC or mplayer when on battery (and I believe VLC by default only uses CPU, not GPU to decode), whereas I haven't got such problems with VLC on Windows (which made me think it wasn't coming from a BIOS option, plus every option in the BIOS regarding the CPU is turned ON).

• Very Cool &ndash; Miami 311 System for tracking citizen service requests (Windows Azure, Silverlight

  - by Jim Duffy

  Having grown up in South Florida this short, but very enlightening, video explaining how the City of Miami has implemented a 311 citizen service request system using Windows Azure, Silverlight and Bing Maps definitely caught my attention. Miami311 The Miami311 System is a Windows Azure/Silverlight-based solution which enables City of Miami citizens report and track issues reported to city management. The system uses Bing Maps to plot the location and relevant information about each issue reported. Citizens now have the ability to easily see the status of the issue without having to call the city office. What I found interesting were a couple of benefits that a metropolitan area such as Miami can take advantage of in Windows Azure cloud-based solution. For the city of Miami, both benefits center around the weather. Of course the threat of a hurricane is a real issue in South Florida and what better way to make sure your site stays up during a hurricane then to have the site hosted far away from the eye of the storm. Using a Windows Azure cloud-based architecture the City of Miami is able to host the application within the Microsoft data centers safely away from any hurricane passing through South Florida. The second benefit is the inherent scalability of a Windows Azure based solution. During a severe weather event like thunderstorms or even worse, a hurricane, downed trees and power lines are a commonly reported problem. Being able to quickly scale up the computing resources required to handle the spike in citizens reporting these types of problems on the site is a huge benefit. Once the weather event has passed and downed tree reports begin to subside they can quickly reverse the process and scale the system back down to pre-storm levels. It’s kind of day-to-day kind of stuff but very cool stuff nonetheless. Have a day. :-|

• Did something just get borked with glibc/perl/irssi?

  I was using irssi about 30 minutes ago now on Ubuntu server 12.04. Everything was perfectly fine and then all of the sudden something happened (my guess is a power failure). The box was restarted.

  I am trying to make my own Live USB and I have successfully generated an ISO file with a newly installed, configured and customized Xubuntu 12.04 LTS installation. My problem is that, no matter I boot the ISO in VirtualBox or in GRUB with loopback, it just cannot start the lightdm. When booting, I can see the log messages on the screen, it stucks at Stopping System V compablities or Configuring Network security. And tty7 is frozen... If I switch to tty1, I can get a logged-in shell as ubuntu@ubuntu. The weird thing is: When I type sudo start lightdm or just sudo lightdm, it will switch to tty7 and the screen flashes. Then nothing happened. Return to tty1 and I can see lightdm running, process xxxx. But the process does not exist. It was just crashed immediately I think. (That's why the screen flashes.) However, when I type startx, I can get into the desktop! That's amazing for me. I am not very clear about the relationship between X Server and Display Manager, but I think lightdm is running when I see the desktop! Then, what's wrong with sudo start lightdm? I use this command every time I power on my laptop since I have a text parameter added in grub.cfg. It never "crashed immediately". I need to use sudo start lightdm because it gets me into "Xubuntu Session" instead of "Xfce Session", the prior is more beautiful... Could anyone help?

• How do I fix a garbled screen on a Gateway LT3103u?

  - by paracaudex

  I've been having garbled screen problems on a Gateway LT3103u on Ubuntu for a while. I just did a fresh install of Ubuntu 11.10 and continue to have issues. I installed xubuntu-desktop in case the issues had to do with the sophisticated GNOME graphics. The problem is less bad, but it's still there. After a few minutes of using XFCE, the screen gets garbled. I assume this has something to do with the graphics card, but I don't know how to go about troubleshooting something like this. Where should I start? Update: Here is the description of the VGA card from lspci -vvv: 01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series] (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 028c Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast TAbort- SERR- [disabled] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: radeon Kernel modules: radeon Update: Setting GRUB_CMDLINE_LINUX="nomodeset" in /etc/default/grub seems to have fixed it in both Ubuntu and xubuntu-desktop. I will test it for a day or so to see if the problems recur and then post more detail with some links to an explanation. Update 2: It is possible to use this fix for Nvidia card (GTX 260) when graphics is defective after 11.10 upgrade/install? First few restarts was graphic ok, then after few restarts begins suddenly be defective and it stay so. I must returned to 11.04 because this problem and I wait for 12.04. So I hope in this fix.

• Canon MG6100 series USB Printer not mounting

  - by user35201

  Printer MP6150 driver installed itself upon plugging in the printer. Printer is recognized (lsusb shows it) but does not mount. If the printer is recognized, the driver must be working (or?), but something is blocking the system from mounting the printer. Tried the usual things: power of printer, restart Ubuntu etc. Listed below result of lsusb and fstab: hans@kontor-linux:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 004: ID 04a9:174a Canon, Inc.

• Monitor not detected after booting without monitor attached (12.04)

  - by cawkie

  I had a stable 12.04 machine running perfectly. The machine was booted without the monitor connected - since then the system always boots to low graphics mode. Onboard graphics (from lspci): VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) Monitor: AOC e2450Swh Display widget shows monitor as laptop(!?) and system details shows graphics as Gallium 0.4 on llvmpipe (LLVM 0x300) X-server log appears to show correct monitor detected. When I boot from a live CD I get full 3d graphics I've tried the monitor on a different machine - all OK. I've tried a different monitor on this machine - same problem. Between having a working system and a broken one there have been no updates and I have made no configuration changes... EDIT: I have come to the conclusion that the problem is caused by a known issue with lightDM hanging on battery check. I've managed to get 3D graphic working by switching to using GDM - not a solution but acceptable workaround. I would still like to know what is causing the problem and how I managed to get my system into this state!

• Access Violation when trying to bind Vertex Object Array

  - by Paul

  I've just started digging into OpenGL and I've run into a problem trying to set a VOA. It's giving me a run-time error of : An unhandled exception of type 'System.AccessViolationException' At // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); I have searched the internet high and low for a solution and I haven't found one. The rest of my function looks like this: int main(array<System::String ^> ^args) { // Initialise GLFW if( !glfwInit() ) { fprintf( stderr, "Failed to initialize GLFW\n" ); return -1; } glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 0); // 4x antialiasing glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3); // We want OpenGL 3.3 glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3); glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); //We don't want the old OpenGL // Open a window and create its OpenGL context if( !glfwOpenWindow( 800, 600, 0,0,0,0, 32,0, GLFW_WINDOW ) ) { fprintf( stderr, "Failed to open GLFW window\n" ); glfwTerminate(); return -1; } // Initialize GLEW if (glewInit() != GLEW_OK) { fprintf(stderr, "Failed to initialize GLEW\n"); return -1; } glfwSetWindowTitle( "Game Engine" ); // Create and bind a VAO GLuint vao; glGenVertexArrays(1, &vao); glBindVertexArray(vao); glfwEnable( GLFW_STICKY_KEYS );

• Which language meets my needs? [closed]

  - by Gerald Goward

  I am a junior C# developer, working for half a year now. In my company I am working on some enterprise projects and after doing it for quite some time I understood that I dont like enterprise projects. I have my own browser-game written in PHP+MySql with some simple HTML+CSS and I have 300 active (those, who entered the game at least once per 5 days) players currently :) After thinking quite some time I understood that I am interested in: 1). Web-development AND 2). standalone programs (but not enterprise ones). 3). Development for mobile platforms is also nice, Android/iOs. 1st and 2nd categories are what I want the most. Android/iOs is good too. I am NOT interested in big systems which are hard to integrate, I am not interested in enterprise systems. In future I would like to start my own business/projects. I would like to create my own projects or/and create a small programmers company to create and release own products. Please tell me what programming language(s)/technologies would you advice me for it? Thanks alot! UPD: It's NOT a "which language is better" or any flame/holywar generating topic since I ask for language that suits my EXACT needs better. I believe C++ is better for low-level coding, while PHP is good for web-development and Object-C being made for iOs. I am still newbie at programming so dont hate me please.

• Is there any way to kill a zombie process without reboot?

  - by Pedram

  Is there any way to kill a zombie process without reboot?Here is how it happens: I wanted to download a 12GB torrent.After adding the .torrent file, transmission turned into a zombie process.I tried ktorrent too.Same behavior.Finally I could download the file using µTorrent but after closing the program, it turns into a zombie as well. I tried using kill skill and pkill with different options and -9 signal but no success. In some answers in web I found out killing the parent can kill the zombie, but killing wine didn't help either. Is there another way?
