• Compiz slow under proprietary nvidia driver

  - by gsedej

  Hi! I am using Ubuntu 10.10 and have problem with proprietary nvidia driver for my GeForce GTS 250. I have issue with poor Compiz performance. And there is also open-source "noueau" driver. Proprietary: I tried many versions but neither works fast on desktop. This means 30 FPS without heavy effects. Currently I am using version 270.18. Even normal desktop use feels bad (moving windows) In games (and 3D benchmark) it is really good! (Unigine Heaven works good!) Open-source "nouveau": Very fast on desktop with heavy effects (blur, ...). I have 300 FPS and more, even in Expo mode. Games were good but not as good as prop. And driver causes xorg to crash even the latest (ppa:xorg-edgers/nouveau), so I switched back to proprietary. I also have computer with Ubuntu 10.04, GeForce 8600GT and drivers around 185.x and Compiz works great there. There is similar question Nvidia proprietary driver performance in 10.10 Which version of nvidia (prop) driver is fast in Compiz in Ubuntu 10.10? How do you install a specific version of nvidia driver? Is it the case that each newer driver works slower on compiz?

• MacOS X 10.6 Portable Home Directory sync fails due to FileSync agent crashing

  - by tegbains

  On one of our cleanly installed MacPro machines running MacOS X 10.6.6 connected to our MacOS X 10.6.6 Server, syncing data using Portable Home Directories fails. It seems to be due to the filesync agent crashing during the home sync. We get -41 and -8026 errors, which we are suspecting are indicating that there is too much data or filesync agent can't read the files. The user is the owner of the files and can read/write to all of the files. < Logout 0:: [11/02/04 13:10:42.751] Error -41 copying /Volumes/RCAUsers/earlpeng/Library/Mail/Mailboxes/email from old imac./Attachments/12081/2.2.

• How do I find a programming internship / practice?

  - by user828584

  I'm taking the SAT soon, and quickly heading toward the chaos of figuring out which college's I will be able to attend, and how on Earth I'll be able to afford it. I would like to be able to gain some experience in programming or web development, but I don't know where to look. I've been trying my best to learn over the past year, and have been doing alright in C# and the web languages (HTML, PHP, CSS, javascript). I have no idea where to look though. I've asked similar questions and rummaged through old questions on here, and they all say nothing specifically. The main two points are always "Contribute to open source projects" and "Find a company and ask to be a part of it." I don't know how to find either of the two. I've looked online at github and source forge, and the like, but all the projects are already so progressed and I just don't have the experience needed to bring myself up to speed with their code. I don't have much experience in code management, and I don't know how to get it. I would be ecstatic to be able to start a project with a group of more experienced members, but, like I said, I have no clue how to find these people.

• Small, fast shopping cart setup

  - by R..

  I'm looking for an open source shopping cart solution that's simple and easy to setup. The requirements are: Quick setup for someone familiar with *nix webservers. Checkout via PayPal (other payment methods not needed). Customers should not have to create an account to make a purchase. At least a minimal level of inventory control. Ability to print/export a list of orders in compact form. Any recommendations for something I should try? Ability to get it up and working quickly is really my priority right now; if it's not ideal, it can be replaced (or, as I'm looking for open source, I can adapt it to fit the requirements better) at a later time. Edit: Really what I'm looking for is simplicity. This will be for a small local business, and the orders will consist of 1-10 items that are being delivered by a driver who needs a simple list of what each customer received when making delivery. Looking like a giant online computer/electronics/etc. store is definitely not a desirable quality. The simpler the interface presented to customers (who are used to purchasing through dumb web forms and paying COD), the better.

• SNMP keeps crashing

  - by jldugger

  We're using OpsView/Nagios to monitor our servers. We've added the SNMP service to all our servers and deployed the configuration via GPO, but one win2k3 server seems to have a problem; it crashes pretty regularly. The event log carries messages like: Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7034 Date: 6/11/2009 Time: 7:11:49 PM User: N/A Computer: HOSTNNAME Description: The SNMP Service service terminated unexpectedly. It has done this 2 time(s). and also Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 6/11/2009 Time: 7:11:18 PM User: N/A Computer: HOSTNAME Description: Faulting application snmp.exe, version 5.2.3790.3959, faulting module ntdll.dll, version 5.2.3790.3959, fault address 0x000417af. Now, I could probably set it to simply restart on crash in perpetuity, but I think it's better to fix problems like this. Is this a known problem? If not, what should I do to diagnose it?

• Storing data for use on Android and Windows Applications

  - by Andy Mepham

  I posted this last night on StackOverflow and was advised to move it over to StackExchange, thank you for taking a moment to look at my question. I'm developing a project proposal for my final year project at University and as I aim to use programming languages I am currently not too familiar with I'm looking for some guidance - I can't include details of my project but hopefully you will understand what I'm after. I'm going to be creating an Android application (in Java) and a Windows Application (in C#) that will ideally access, query and update a remotely hosted Database or set of XML files (this would most likely be over the Internet). I've done some looking around the internet and SQLite seems like a safe-bet for cross-platform manipulation of the database; however I would like to keep the system as lightweight as possible and I'm wondering whether XML files may provide a better alternative? Anyone out there that has experience using SQLite and/or remotely hosted XML for the purposes of Android and/or C# development that could point me in the right direction? If there is an alternative solution other than those I have mentioned I would be interested to hear about them too. Thank you for taking the time to read my question. Edit: The purpose of this application is for a small scale business, the data source would not need to be updated by more than one source but may be view from multiple sources (i.e. through multiple phones and a desktop PC). The database wouldn't be updating masses of data at a time (most likely single rows of a few tables at the most).

• To branch or not to branch?

  - by Idsa

  Till recently my development workflow was the following: Get the feature from product owner Make a branch (if feature is more than 1 day) Implement it in a branch Merge changes from main branch to my branch (to reduce conflicts during backward merging) Merge my branch back to main branch Sometimes there were problems with merging, but in general I liked it. But recently I see more and more followers of idea to not make branches as it makes more difficult to practice continuous integration, continuous delivery, etc. And it sounds especially funny from people with distributed VCS background who were talking so much about great merging implementations of Git, Mercurial, etc. So the question is should we use branches nowadays?

• Windows Server 2003 W3SVC Failing, Brute Force attack possibly the cause

  - by Roaders

  This week my website has disappeared twice for no apparent reason. I logged onto my server (Windows Server 2003 Service Pack 2) and restarted the World Web Publishing service, website still down. I tried restarting a few other services like DNS and Cold Fusion and the website was still down. In the end I restarted the server and the website reappeared. Last night the website went down again. This time I logged on and looked at the event log. SCARY STUFF! There were hundreds of these: Event Type: Information Event Source: TermService Event Category: None Event ID: 1012 Date: 30/01/2012 Time: 15:25:12 User: N/A Computer: SERVER51338 Description: Remote session from client name a exceeded the maximum allowed failed logon attempts. The session was forcibly terminated. At a frequency of around 3 -5 a minute. At about the time my website died there was one of these: Event Type: Information Event Source: W3SVC Event Category: None Event ID: 1074 Date: 30/01/2012 Time: 19:36:14 User: N/A Computer: SERVER51338 Description: A worker process with process id of '6308' serving application pool 'DefaultAppPool' has requested a recycle because the worker process reached its allowed processing time limit. Which is obviously what killed the web service. There were then a few of these: Event Type: Error Event Source: TermDD Event Category: None Event ID: 50 Date: 30/01/2012 Time: 20:32:51 User: N/A Computer: SERVER51338 Description: The RDP protocol component "DATA ENCRYPTION" detected an error in the protocol stream and has disconnected the client. Data: 0000: 00 00 04 00 02 00 52 00 ......R. 0008: 00 00 00 00 32 00 0a c0 ....2..À 0010: 00 00 00 00 32 00 0a c0 ....2..À 0018: 00 00 00 00 00 00 00 00 ........ 0020: 00 00 00 00 00 00 00 00 ........ 0028: 92 01 00 00 ... With no more of the first error type. I am concerned that someone is trying to brute force their way into my server. I have disabled all the accounts apart from the IIS ones and Administrator (which I have renamed). I have also changed the password to an even more secure one. I don't know why this brute force attack caused the webservice to stop and I don't know why restarting the service didn't fix the problem. What should I do to make sure my server is secure and what should I do to make sure the webserver doesn't go down any more? Thanks.

• Scrolling a WriteableBitmap

  - by Skoder

  I need to simulate my background scrolling but I want to avoid moving my actual image control. Instead, I'd like to use a WriteableBitmap and use a blitting method. What would be the way to simulate an image scrolling upwards? I've tried various things buy I can't seem to get my head around the logic: //X pos, Y pos, width, height Rect src = new Rect(0, scrollSpeed , 480, height); Rect dest = new Rect(0, 700 - scrollSpeed , 480, height); //destination rect, source WriteableBitmap, source Rect, blend mode wb.Blit(destRect, wbSource, srcRect, BlendMode.None); scrollSpeed += 5; if (scrollSpeed > 700) scrollSpeed = 0; If height is 10, the image is quite fuzzy and moreso if the height is 1. If the height is a taller, the image is clearer, but it only seems to do a one to one copy. How can I 'scroll' the image so that it looks like it's moving up in a continuous loop? (The height of the screen is 700).

• What is the politically correct way of refactoring other's code?

  - by dukeofgaming

  I'm currently working in a geographically distributed team in a big company. Everybody is just focused on today's tasks and getting things done, however this means sometimes things have to be done the quick way, and that causes problems... you know, same old, same old. I'm bumping into code with several smells such as: big functions pointless utility functions/methods (essentially just to save writing a word), overcomplicated algorithms, extremely big files that should be broken down into different files/classes (1,500+ lines), etc. What would be the best way of improving code without making other developers feel bad/wrong about any proposed improvements?

• Can anyone recommend an AI sandbox?

  - by user19433

  I'm passionate person, who has been around AI from a long time [1] but never going in deep enough. Now it's time! I've been really looking for some way to concentrate on AI coding but couldn't succeeded to find an AI environment I can focus on. I just want to use an AI sandbox environment which would let me have tools like: visibility information character controller able to easily define a level, with obstacles of course physics collider management triggers management don't need to be a shiny, eye candy graphical render : this is about pathfinding, tactical reasoning, etc.. I have tried : Unreal Dev Kit : while the new release announce is about C++ coding, this is about external tools and will be released in 2013 Cry Engine : really interesting as AI is presents here but coding with it appears to be an hell: did I got it wrong ? Half Life source, C4, Torque, Dx Studio : either quite old, not very useful or costly these imply to dig in documentation (when provided) to code everything, graphics included. Unity 3D : the most promising platform. While you also need to create your own environment, there are lot of examples. The disadvantage is, in addition to spend time to have this env. working, is the languages choice : C#, Javascript or Boo. C# is not that hard, but this implies you'll allways have to convert papers (I love those from Lars Linden) books codes, or anything you can have in Aigamedev are most often in C++. This is extra work. I've look at "Simple Path", the very good Arong Greenberg work but no source provided and AngryAnt work. AI Sandbox : this seems to be exactly what as AI coder I want to use. I saw some preview but from 2009 we still don't know what it will be about precisely, will it be opensource or free (I strongly doubt), will I be able to buy it? will it really provide me tools I need to focus on AI ? That being said, what is the best environment to be able to focus on AI coding only, is it even possible?

  I want to distribute my software under license like Creative Commons Attribution - Non commercial - Share Alike license, i.e. Redistribution of source code and binaries is freely. Modified version of program have to be distributed under the same license. Attribution to original project should be supplied to. Restrict any kind of commercial usage.

Better if public license, but as far as I know US laws says that only EULA could restrict usage of received copy?

• Piping powershell messages to Write-EventLog

  - by Richard

  I have a powershell script that runs a custom cmdlet. It is run by Task Scheduler and I want to log what it does. This is my current crude version: Add-PsSnapIn PianolaCmdlets Write-EventLog -LogName "Windows Powershell" -Source "Powershell" -Message "Starting Update-EbuNumbers" -EventId 0 Get-ClubMembers -HasTemporaryEbuNumber -show all | Update-EbuNumbers -Verbose Write-EventLog -LogName "Windows Powershell" -Source "Powershell" -Message "Finished Update-EbuNumbers" -EventId 0 What I would like to do is log the output of my custom cmdlet. Ideally I'd like to create different types of event log entries based on whether it was a warning or a verbose message. Update: I don't want to log the return value of the commandlet. The Update-EbuMembers cmdlet does not return an object. I want to log any verbose messages written by WriteVerbose and I want to log errors created by ThrowTerminatingError.

• Does a Samsung G3 Station external hard drive stop working when power supply is too high?

  - by Cacovsky

  I have a Samsung G3 Station 2TB external hard drive (link to PDF specs here). It was working perfectly when I accidentally plugged it in my notebook's power source. The notebook's power source is 19V/3.42A. The hard drive's is 12V/2A and I know that, inside its case, there is regular 2TB SATA drive, along with some sort of adapter. Does this adapter has some kind of power protection? I opened the case and the hard drive board smells bad. Does my data is forever lost or can I replace its board?

• OpenBSD ftp-proxy behind NAT itself

  - by Manuel Faux

  Is it possible to change the PASV IP ftp-proxy of OpenBSD sends to clients, without changing the listen address of redirection control (-b <address>)? I have the following setup: FTP client --> 1:1 NAT router --> OpenBSD router --> FTP server The 1:1 NAT router has a NAT rule to forward everything to the OpenBSD router, the OpenBSD router runs the ftp-proxy -R <FTP server IP>. When the FTP client sends the PASV command, the proxy answers with the Entering Passive Mode (227) message with his own source IP on the interface to the 1:1 NAT router (obviously). Since the 1:1 NAT router is not protocol aware, it forwards this message and the client receives the message with the PASV IP of the OpenBSD router, which it does not have a route to. Is there a way, that I can tell ftp-proxy to send the Entering Passive Mode message with a different source IP?

• Linux: How to break a large file into smaller files?

  - by Runcible

  I have a giant file (20 gigs) sitting on my source machine and I need to transfer it to my target machine. For the purposes of this question, let's assume that I do not have network connectivity between the two machines. I need to break this file into a series of smaller files, write the smaller files to DVD(s), then re-assemble everything on the target machine. Both source and destination machines are Linux boxes. Is there a way to accomplish this using tar? I have a feeling that I need to use the --multi-volume parameter. What are my options? I need to be able to specify the size of the volume files, in order to make sure that each one will fit onto a single DVD. Thanks!

• Software development magazines [closed]

  - by Sebastian

  Ive spent the last hour or so browsing the web for professional development magazines. I am mostly interested in the java platform, agile methods, "programming in general" (tutorials on languages or whatever, "hot new stuff" etc) and software craftmanship. My best finding yet was pragpub and maybe MSDN magazine. I am willing to pay and have a Zinio account if anyone knows a magazine about programming that is distributed by them. Ive already browsed a couple of related threads here on stackexchange. ACM and IEEE does not seem relevant, as Im not interested in research articles. Maybe conferences like OOPSLA as somebody mentioned in another thread. PS. I prefer if they are in pdf or readable on kindle or a tablet. DS. BR Sebastian

• Radeon 9200 Driver?

  - by usuhh86

  I've been using Linux for a while, but haven't really done more than installed programs. I have Ubuntu 12.04 with an ATI Radeon 9200 graphics card. Ubuntu didn't recognize it during the install. All I want is a driver. Preferably the proprietary driver, but I'll settle for an open-source one if I need to. I went to the AMD support website, and whenever I click on the download link for "ATI Proprietary Linux x86 Display Driver 8.28.8" I get redirected to the main AMD website. I tried this on Firefox, Chrome, even booted up my netbook and tried it on IE9. Does anybody have a download link? And if not, a link to download an open-source alternative? Any help will be greatly appreciated. I'm pretty much still a newbie at this. OpenGL vendor string: Tungsten Graphics, Inc.

• crontab environment

  - by Adamski

  I have written various scripts to launch Java server applications, which are typically run for 24 hours before being shut down (by invoking the same script with a different parameter). The script relies on environment variables defined in a file: ~/<user>.env, which I source from .bashrc. This works fine when invoking the script from the command line but if I want to add the script as a crontab entry I run into the problem where .bashrc isn't read. My question: What is the best practice approach for solving this problem? I realise I could define a crontab entry such as: * * * * 1-5 /usr/bin/bash -c '. /home/myuser/myuser.env && /home/myuser/scripts/myscript.sh' ... but this seems plain ugly. Alternatively I could source myuser.env at the beginning of every script, but this would become a nightmare to maintain. Any help appreciated.

• Sonicwall Enhanced With One-To-One NAT, Firewall Blocking Everything

  Hello, just migrated from a Sonicwall TZ180 (Standard) to a Sonicwall TZ200 (Enhanced). Everything is working except the firewall rules are blocking everything. All hosts are online, and being assigned correct ip addresses. I can browse the internet on the hosts. I am using one-to-one NAT translating public ip addresses to private. 64.87.28.98 -> 192.168.1.2 64.87.28.99 -> 192.168.1.3 etc First order of business is to get ping working. My rule is in the new firewall is (FROM WAN to LAN): SOURCE DESTINATION SERVICE ACTION USERS ANY 192.168.1.2-192.168.1.6 PING ALLOW ALL This should be working, but not. I even tried changing the destination to the public ip addresses, but still no luck.

• svn vs git for the sole developer? [closed]

  - by nattyP

  If I am sole developer (I do not work in a team) working from my laptop (Windows OS and Linux VM) and backing up data to the cloud (Dropbox etc), then is git still better than svn for my version control needs? I was thinking not since I wont need any of git's distributed features. But is git such a better approach to version control that I should consider moving anyway? With so many articles saying how people are moving from svn to git? I was wondering, if they are talking about large or open projects with teams of developers vs the sole developer. What do you think?
