• Why is my Windows XP not allowing me to turn on sounds?

  - by Rookie

  This started to happen few weeks ago: Every time I start up Windows, the global sound volume is set to muted. I was able to just click the muted button to un-muted and that was fine, until now: Now I cant even click that unmute button! Every time I click the unmute button, I hear a split of a second the music I play, then it stops immediately. It is maybe 10 milliseconds until it mutes it again. In theory I could write a program to click that button continuously, but is there another solution to fix this? Or is this a broken hardware problem and Windows knows it and therefore doesn't allow me to enable sounds or my computer would break apart? Any ideas what could be causing this? A weird virus that's purpose is to piss me off? That weird this whole issue is, really, doesn't make any sense at all.

• Thunderbird: filters don't match links

  - by Gregory MOUSSAT

  I use filters to remove some undesirable messages (in addition to the intergrated spam filter). This is great to avoid tons of boring people who want to sell me tons of boring stuff. My problem is, since years (so with every Thunderbird release I ever had, even the current one which is up to date) it is unable to filter links. For example I want to delete every messages containing a link to http://xxxxx.emv3.com/xxxxxx I never managed to remove those emails. I use a filter on the body, checking if it contains emv3 but this never match. Those emails are in HTML format, and the links are displayed as a text like "Visit our website" or so. If I write a HTML email with a link, my filter works. When this is a spam, this never works. When I save the email to a text file, I open it with notepad and I see several http://xxxxx.emv3.com/xxxx Any idea why this don't work ? And how can I do ?

• Is there a PROPRIETARY driver (NVIDIA or ATI) that actually works with 12.10?

  - by DS13

  NOTE: I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. THE MAIN DIFFERENCE SEEMS TO BE: I always get a black screen with a blinking cursor, while others seem to get through the boot-up and see distorted graphics or just their wallpaper. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics (even just menus) are very slow, choppy, and distorted. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: -Does anyone know of a PROPRIETARY driver that will actually work on 12.10 with a NVIDIA or ATI card? -Should I just buy a newer graphics card to put in as a replacement? MORE INFO: This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent'ish Core2Duo Intel processor (2.13Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card (NVIDIA Geforce 7350 LE) is holding me back. TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -tried installing 12.04 *same results -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail -UPDATE- Re-tried everything above with a new NVIDIA Geforce 210...same results for everything. -UPDATE #2- Re-tried everything above with a new AMD Radeon HD 6450...installed the proprietary driver from Ubuntu's "Software Sources" menu...EVERYTHING NOW WORKS. See "answer" below for summary.

• How can you easily determine the textureRect for tiled maps in SFML 2.0?

  - by ThePlan

  I'm working on creating a 2d map prototype, and I've come across the rendering bit of it. I have a tilesheet with tiles, each tile is 30x30 pixels, and there's a 1px border to delimitate them. In SFML the usual method of drawing a part of a tilesheet is declaring an IntRect with the rectangle coordinates then calling the setTextureRectangle() method to a sprite. In a small game it would work, but I have well over 45 tiles and adding more every day, I can't declare 45 intRects for every material, the map is not optimized yet, it would get even worse if I would have to call the setTextureRect() method, aside from declaring 45 rectangleInts. How could I simplify this task? All I need is a very simple and flexible solution for extracting a region of the tilesheet. Basically I have a Tile class. I create multiple instances of tiles (vectors) and each tile has a position and a material. I parse a map file and as I parse it I set the materials of the map according to the parsed map file, and all I need to do is render. Basically I need to do something like this: switch(tile.getMaterial()) { case GRASS: material_sprite.setTextureRect(something); window.draw(material_sprite); break; case WATER: material_sprite.setTextureRect(something); window.draw(material_sprite); break; // handle more cases }

• How to sync apps with one Mac and 3 devices?

  - by openfrog

  We have 1 Mac, with 1 iTunes account, and 3 iOS devices. Every time we sync one device, iTunes either spams it with ALL apps from ALL devices, OR it removes all of the apps from the device including all the data. Which is very annoying. Someone told me there is a way to tell iTunes to keep separate track of the devices. How can I setup iTunes such that it will not transfer all my iPhone-only apps to my iPad every time I sync? Basically I want the devices to be the "master". They give the direction which apps should be on the device, and not the other way around.

• Issues trying to download Windows 8.1 using official downloader

  - by Aviral Singh

  I had been trying to download Windows 8.1 ISO from the last 3-4 days but a silly issue is preventing me to download it.As many posts over the internet explain,I tried to use generic keys to download(as I don't have Windows 8),but the installer always shows "We can't connect right now,please check you internet connection.".Isn't it silly?,I have a working internet connection.No matter whatever key I use it always ends at this message.I've tried every single generic key,and almost every key was accepted by the installer as valid,but then the message. Can anyone please explain why is this happening and any workarounds ?

• What is Paging in memory management?

  - by Fasih Khatib

  I was just reading Operating System Principles by Silberschatz et al when I came across paging in memory management.I'm slightly confused about it. It states that Physical Memory(I assume it's RAM) is divided into frames, and logical memory is divided into pages. CPU generates logical addresses containing page number and an offset. This page number is used to retrieve the frame number from a page table which gives the base address so the physical address is calculated as base+offset. My question is: is the page table maintained for every process? I logically think that the answer would be yes as every process will need to map its own pages to frames. I may be wrong. Please clarify. Also: paging and segmentation(where 'holes' are created in memory) are two totally different techniques that are not used in combination. Correct?

• Strange Intermittent Background Sound in Windows 7

  - by NoCarrier

  Ok, this is very strange. Recently, i noticed that every 10-15 seconds, there would be this faint, annoying duh-dum sound coming out of my speakers. (hard to describe. sounds somewhat like the sound windows makes when you unplug a USB device, but not as pronounced and much quieter). I closed every app and ended as many processes as I could, but the sound persists. I look at the volume mixer and sure enough, when the sound occurs, there is a little spike in the level under "System Sounds". I haven't installed any hardware or software in the last several weeks. This started recently - completely out of the blue. Does anyone have any insight?

• Very frequent "Server not found" messages

  - by Village

  Recently, while browsing and clicking or typing an address, I get: "Server not found", "Connection was reset", or a half-loaded page. Usually the page loads instantly after clicking reload, but this means I must reload on every page. Images on one site, but stored at a different server don't load until reloading for a second time. Clicking "submit" on many sites frequently doesn't work unless I reload many times. Sometimes sites load, but without colors and formating, appearing as if they would in Lynx. This seems to happen with every Web site. My Internet service claims everything on their end is fine. This happened a day after running an update in aptitude. I have not updated any hardware. I have tried clearing Iceweasel's cache. I do not have any router or other equipment. What could be going on? How can I troubleshoot this? PPPoE connection, Iceweasel 3.5.16, Debian 6

• Let a program (called by other program) run as admin without prompt

  - by DarkGhostHunter

  As you may know, Steam doesn't like no-admin accounts for installing games or whatsoever. In my case, I have a user in my computer that usually install a lot of games and every time I have to put my password to successfully play them. Blame, /bin/SteamService.exe. I came up with a solution: using RunAs to make Steam run as the admin user. But that is a potential security risk. So instead of that, I'm asking if is possible to do the following: Hot to run SteamService.exe with high trust levels (or admin privileges) automatically when Steam calls it? That way he can play and install games in Steam leaving the rest of the system alone. I don't mind if the user has to click "yes or no", but without prompt its better because some games asks every time they're executed.

• Multi-monitor resolution and position settings lost after reboot

  - by SoftDeveloper

  I've had two 1280x1024 monitors running for years on an nVidia 8800GT card with no problems. I've now replaced one monitor with a new 2560x1440 one. The card seems to support both fine, however every time I reboot the resolutions and monitor positions revert to the old settings. I've tried upgrading, downgrading, stripping out and reinstalling many versions of the nvidia drivers to no avail. Logging in as another user doesn't help - same problem. Booting into another another OS (Win7 64) works OK, so it is just this OS installation. During boot up everything looks fine (ie native 2450x1440 res) until the nVidia control panel or something is loaded which flips it back into the old mode. I have no old saved nvidia profiles. I can't find anything in the registry relating to these old settings. Its driving me crazy having to set resolutions and realign monitors on every reboot! Can anybody help?

• Do you do custom tests/work for a potential employer before the interview?

  - by Chuck Stephanski

  Every shop I've worked at we have followed what I thought was a standard hiring sequence: 1. solicit resumes 2. phone screen applicants we are interested in 3. in person interview 4. in some shops 2nd in person interview (just w/ CEO for example) Most places I apply to follow something along these lines. But some shops want to give me a test or ask me to build something after I send in my resume. They usually say "congratulations, you've made it to stage 2 of our hiring process!" But for all I know they are asking every applicant they get a resume from to do the same thing. This annoys me because it doesn't scale. If I'm applying for a lot of positions I can't spend all my time doing work that potentially can only land me one job. Plus there's no shared dedication to the process. If we do a 45 minute phone screen, that's 45 minutes the company commits to me and 45 minutes I commit to the company in hopes of a potential match. Do you guys have a policy regarding these sorts of things?

• How to migrate Notepad++ settings?

  - by NoCatharsis

  I am trying to portabilize every program I use if possible, and Notepad++ is on the list. The only problem is that I've had a native installation until now so that I'm not totally sure which settings files need to be moved to the portable directory. Surely there's a function tucked away somewhere in NPP exactly for this purpose, or some plugin out there? I mean the developers have literally thought of everything else, yet this is the one thing I cannot find specifically anywhere in the NPP wiki or otherwise, and I don't want to miss an important file. Here is the closest I've gotten: Notepad++'s configuration files and Where are all the files? Should I just copy every configuration file listed on the first link?

• Options to efficiently synchronize 1 million files with remote servers?

  - by Zilvinas

  At a company I work for we have such a thing called "playlists" which are small files ~100-300 bytes each. There's about a million of them. About 100,000 of them get changed every hour. These playlists need to be uploaded to 10 other remote servers on different continents every hour and it needs to happen quick in under 2 mins ideally. It's very important that files that are deleted on the master are also deleted on all the replicas. We currently use Linux for our infrastructure. I was thinking about trying rsync with the -W option to copy whole files without comparing contents. I haven't tried it yet but maybe people who have more experience with rsync could tell me if it's a viable option? What other options are worth considering?

• Long domain lookup on .dev domain inside vmware

  - by skelle

  I'm developing on my macbook and normally I have a local running webserver which just works finde. Now I have to use a vmware image where the webserver is running. I set up everything and my dev site is running under site.dev inside vmware. I can connect to the webserver but EVERY request takes a very long time. I already red that this is related with iIPv6 and the way OSX handles /etc/hosts. There I added 192.168.155.42 site.dev and I already did this (Resolving to virtual host very slow on Mac OS X Lion) but my lookup still takes ~30seconds on every request. What can I do to fix this issue?

• How do you override the warning "filename is not commonly downloaded" for a specific file?

  - by Oliver Salzburg

  There is a specific file on a customers server which I require to connect to one of their services. The contents of the file are confidential and the file is not intended for the public. Thus, the file is not "commonly downloaded", and every time I need to download it, I get this warning: I have to download that files sometimes multiple times a day (the contents of the file change periodically) and, every time, I have to click through this little annoyance. The Phishing and malware detection page only explains how to disable the feature completely, which is not what I want at all. Can I disable this feature for a single given URL?

• Making Thunderbird auto-add SMTP identities whenever I reply

  - by 0xC0000022L

  How can I teach Thunderbird to automatically add an SMTP identity whenever I reply to an email directed to <whatever>@<mydomain>? So if an SMTP is configured for <mydomain> but no identity exists for <whatever>@<mydomain>, how can I make Thunderbird dynamically recognize this and add it. Currently I have to manually add the identity every single time, but I would prefer it to to be added ad-hoc. As long as Thunderbird was configured to know about the SMTP serving <mydomain> this should be trivial, but I couldn't find an option. An add-on or something like a catch-all/wildcard identity would also do as long as it doesn't require manually setting up a new identity every time.

• SQL Server database constantly restarting

  - by Michael Itzoe

  We have SQL Server 2008 Express installed on a Windows 2003 server. Looking at the event log, one of the databases appears to be restarting anywhere from every couple seconds to every 15 to 30 minutes. This server hosts about half a dozen databases; the problem is with only one. This database is also the onle one comprised of multiple schemas (not just dbo). There are thousands of events going back several months. There doesn't seem to be any affect on the website using the database, nor does any data appear to be corrupted or compromised. I'm not a DBA, so I don't even know where to look for causes to this. Any suggestions?

• OS X - Automatically Set Execute Permissions for New Files?

  - by i help X u

  I'm using OS X 10.6.4 and am trying to set a folder to automatically enable execute permissions on new script files copied or created in a directory. I have used Sandbox 2 to set every permission for the folder to enabled with sticky bits and the inherit flag set but I still have to manually set the execute flag using chmod for every new flag. I've done: chmod -R a+rwxs ~/scripts I've done: chmod 7777 ~/scripts And the permissions for the folder show as: drwsrwsrwt+ for the folder. But if I add a new script file it's set to "-rw-r--r--+" (the default) I looked at setting "unmask 000" in the .profile file but the default value for files is 666 with an unmask of 022 so that's not relevant since I would need a default value of 777 for files. I have figure out how to use chmod in an AppleScript triggered by a folder action to automate this but I'm wondering if there is a simple ACL or chmod setting I'm missing. So, is there a way to automatically set execute permission for new files? (Without using a folder action and AppleScript?)

• Windows 7 boot error

  - by jason

  I am running windows 7 professional, everything was working fine until I installed a software driver clearner suggested by nvidia customer service and I cleaned only nvidia graphic driver installation since then my windows does not work at all. I can access everything from startup repair, did lots of time repair but nothing happened. System restore does not work it says c: drive is not available, its 100% there and I can access every file from command prompt. Almost two days passed and I applied every solution discussed on several forums, now only thing left is either install fresh windows (Which i really don't want to do) or update windows (which windows does not let me to do, it says I have to update it from windows) My question is there any way to update (not fresh/custom installation) windows from command prompt? P.s: Safe mode, safe mode command nothing works except startup repair option. I ran sfc /scannow no problem found. I also removed all attached hardwares. Any help would be greatly appreciated.

• A Duplicate name exists on the network

  - by Adam

  Recently we changed out office IT structure from having a dedicated server to be the DC, a dedicated server for the exchange etc... (Each running Windows Server 2003 R2) Now we have a single server running Windows SBS 2008 and created a new domain (with a different domain name) We then changed every PC so it connected to the new domain and renamed every PC with a new naming structure. After I had done this, we were getting several PCs that would get the following message just before the login screen (Alt+Ctrl+Del Screen) A Duplicate name exists on the network I have checked the ADUC and have removed the trouble PCs from the list and renamed each PC and changed the SID before connecting back onto the domain but still getting this message. I have tried everything that i can think of but still getting the problem. Any help would be greatly appreticated.

• App Pool crashes before loading mscorsvr. How to troubleshoot?

  - by codepoke

  I have an app pool that recycles every 29 hours, per default. It recycles smoothly 9 times out of 10, and I'm pretty sure the recycle itself is good for the app. Once every couple weeks the recycle does not work. The old worker process dies cleanly and the new worker process starts, but will not serve up content. Recycling the app pool again manually works like a charm. The failed worker process stops and dies cleanly and a second new worker process fires up and serves content perfectly. I took a crash dump against the failed worker process prior to recycling it, and DebugDiag found nothing to complain about. I tried to dig a little deeper using WinDBG, but mscorsvr/mscorwks is not loaded yet 15 minutes after the new process started. There are 14 threads running (4 async) and 20 pending client connections, but .NET is not even loaded into the process yet. Any suggestions where to poke and prod to find a root cause on this?

• Discrete Math and Computing Course

  - by ShrimpCrackers

  I was recently admitted into a Computing and Software Systems program (basically software engineering) and one of the first courses I'll be taking is called Mathematical Principles of Computing. The course description: "Integrating mathematical principles with detailed instruction in computer programming. Explores mathematical reasoning and discrete structures through object-oriented programming. Includes algorithm analysis, basic abstract data types, and data structures." I'm not a fan of math, but I've been doing well in all my math classes mostly A's and B's ever since I started two years ago, and I've been doing math every quarter - never took a quarter without math - so I've been doing it all in sequence without gaps. However, I'm worried about this class. I've read briefly on what discrete math is and from what my advisor told me, its connection with computer science is that it has alot to do with proving algorithms. One thing that my instructors briefly touched on and never went into detail was proving algorithms, and when I tried, I just wasn't very good at mathematical induction. It's one of the things that I ignored every time it showed up in a homework problem (usually in Calculus III which I'm finishing up right now). Questions: 1. What can I expect from this class? 2. How can I prepare myself for this class? 3. Other tips? Thank you.

• Remotely enter encryption key?

  - by Jason Swett

  This might be a really dumb question but here goes, anyway. I just bought a couple servers. I already installed Ubuntu with encrypted LVM on one and I'm planning on doing the same with the other. This means that every time I boot up each of these machines, I have to enter the passphrase. And I'll have to do this every morning because I'll power each machine off each night for security reasons. Here's the problem: I don't have monitors or keyboards for these servers. It seems to me I have two options: Somehow enter the passphrase remotely Buy a KVM switch I doubt #1 is an option but I want to make sure it's not before I buy a KVM. Is it possible to enter the passphrase remotely? AND is it a good idea?
