• Cannot access my own web page

  - by enflam3

  I am developing, learning and experimenting with php,html,javascript,flash and so on. Having web hosting and all of the cpanel, phpmyadmin and other utilities. One day, while updating information, connection between my computer and website just went down. I found out that it is only from this computer, where I cannot access anything. I don't know what is the reason I cannot access website, however this is what I have checked so far: Everything else opens normally, having problem only with my page. Cannot access FTP,cpanel or any kind of information related to the domain and hosting ipconfigs detects IP, but shows request timed out (so its not browser related) Turned off Firewall,AV, Rebooted computer Cleared caches,temp,cookies,histry with CCleaner Checked connectivity with both (wired,wireless) networks ISP has dynamic IP that has been changed about 3 times since issue Checked host file I am out of ideas and understanding what could cause this kind of issue, however couple minutes ago, found out that everything works with proxy server (when adding IP and port to the browsers) Can someone point out what should I check or try to get rid of this problem?

• Nvidia Powermizer Performance Levels

  - by jeffrey

  Is there anyway to configure Nvidia Powerimizer performance levels? My current setup has 3 power levels with the lowest one being 50mhz. The problem with this it that it lags compiz when it goes to the lowest performance level 0. Minimizing, maximizing, dragging windows, etc. are all sluggish when it's at the lowest level. Once powermizer leaves level 0 everything is very smooth and runs great. Is there anyway for me to remove level 0 and just run Level the two higher levels 1/2? I don't want to complete disable powermizer, but I can't stand the lagging once powermizer goes into performance level 0. Setting the option "prefer maximum performance" fixes the problem as it disables powermizer, but the GPU is overkill at stock speeds for most desktop use @ 850mhz. intel i5 2500k asus gene-z z68 evga 560ti fpb (driver 295.40) ubuntu 12.04 LTS x64

• Efficient Bus Loading

  - by System Down

  This is something I did for a bus travel company a long time ago, and I was never happy with the results. I was thinking about that old project recently and thought I'd revisit that problem. Problem: Bus travel company has several buses with different passenger capacities (e.g. 15 50-passenger buses, 25 30-passenger buses ... etc). They specialized in offering transportation to very large groups (300+ passengers per group). Since each group needs to travel together they needed to manage their fleet efficiently to reduce waste. For instance, 88 passengers are better served by three 30-passenger buses (2 empty seats) than by two 50-passenger buses (12 empty seats). Another example, 75 passengers would be better served by one 50-passenger bus and one 30-passenger bus, a mix of types. What's a good algorithm to do this?

• Problems booting Ubuntu 10.10 with Nvdia GeForce 6600gt

  - by SlyrNemesis

  I am quite new to Ubuntu and I already stumbled upon a problem. I run Ubuntu 10.10 Maverick Meerkat now and Install went fine, when trying to boot the screen popped black and I faced this message "gpu lockup - switching to software fbcon." When setting the display to onboard VGA through BIOS Ubuntu has no problem at all, but when I switch back to my AGP card (which is a Nvidia GeForce 6600GT) I get that message again. I do not use VGA for that card I use my DVI cable for it. Does anyone have an answer for me to make this work? Thank you

• How to re-partition?

  - by EDi

  I switched from Windows to Ubuntu 4 months ago and I am really happy with it. I set up a dual-boot system (since I wasn´t sure how it will end up with me and Ubuntu). After merging from Citavi to Zotero I need windows only for my scanner. The problem I have now is, that the windows partion is so big with lots of unused space and the ubuntu partition are quite small - I should have though about this problem 4 months ago... My partitions look like this: Where sda3 is the windows partition, sda5 is Ubuntu and sda7 is a data partition. I want to shrink sda3 and free some space for sda5 and sda3. How can this be done safely (and easily)?

• eth0 not working on startup

  - by user4106

  Hi to all, This might sound strange but, working with my Lubuntu 10.04 i've experienced troubles when connecting to my eth0 newtwork. After some googling, i've found out that by writting in the CLI the following command: mii-tool eth0 -F 10baseT-FD and activating the eth0 in the toolbar (by clicking "activate eth0") everything works just fine. Well, up to now, i did not have any problem, because every time i turned on the computer i had to do this, but it was very little effort.But now, i would like to use the machine as a file server, accesing it by ssh, without monitor or keyboard. So, i won't be able to make this actions, and can't do this at startup because mii-tool needs root permissions. So, the question is: Do you know what does that command do, and how can id make that change permanent? Or do you know any other solution for my problem? I hope i was clear! If not, tell me and i'll try to be as clearer as possible. Thanks in advance!

• I can't log into my ubuntu 12.04

  - by user292674

  When I try to log in on my Ubuntu 12.04 it goes to a black screen ( of logging in checking stuff ), and says Checking battery ----- [ok] ( I'm using a computer instead of a laptop ) and just goes back to the login screen. Two days before I executed the command sudo startx trying to start KDE, but it didn't work. And after logging off and trying to log in again, I had this problem. A big problem is that I don't have internet connection at home. What should I do?

• Fujitsu B6220 laptop, sometimes my desktop freezes upon resume from standby

  - by user89756

  I installed Ubuntu 11.10 on my Fujitsu Lifebook B6220 laptop just before 12.04 was released. I can not remember if I had this issue with Ubuntu 11.10 as I updated the install to 12.04 about a week after 12.04 came out. My problem is that sometimes upon resume from standby my desktop is frozen. The keyboard, touch pad, and touchscreen work, but there is no response from the desktop. I can ctrl-alt-f2 and log in and then from there I just reboot the computer. This happens about 50% of the time when I resume from standby but I have not noticed a distinct pattern. I have thought about reinstalling 12.04, since I upgraded 11.10 to 12.04 instead of a fresh install. But I have customized my laptop a lot and I would prefer to avoid reinstalling it, I'm not even sure if that would fix it. Anyone have a idea what might be the problem? If I should submit this as a bug, could someone point me in the right direction please? Thanks, Matt

• Why is it an issue that it takes 2 digits to represent the number 10 in decimal?

  - by Crizly

  So we use hexadecimal which has the advantage of going up to 15 in single digits A-F, but why is it an issue that it takes 2 digits to represent the number 10 in decimal? I was reading up about hexadecimal and I came across these 2 lines: Base 16 suggests the digits 0 to 15, but the problem we face is that it requires 2 digits to represent 10 to 15. Hexadecimal solves this problem by using the letters A to F. My question is, why do we care how many digits it takes to represent 15? What is the importance of this number, and how does denoting it with a single character have any value?

• Particles are not moving correctly [closed]

  - by cr33p

  I want to make a particle explosion, after something gets destroyed, but somehow only one line of mixed colors show up on the screen. Here's the header: http://pastebin.com/JW5bPLj2 Here's the source: http://pastebin.com/KHmFqytD I don't get what's wrong, as it's nearly the same as in "Programming Linux Games" Can somebody help me fix that? PS: "Uint32 delta" is needed to update the pixels based on time. PSS: Maybe I should add that it's programmed in C and includes SDL. EDIT: Found the problem. It was the "drawParticles" function. The problem was, that I passed a double to "offset" (as particles[i].x, etc are all doubles). So I ended up with values like ~MAX_INT because I didn't cast the doubles properly to ints.

• Mobile traffic of my second site redirected to my base site [Edited,have a look]

  - by Faheem Rasheed

  I have a strange issue with my website and it seems i am unable to understand what cauese the problem.I would highly appreciate your help.The Scenario is I have two websites. Website A Website B Website A is simply hosted within the root directory of my hosting account.Within this root *directory* i have a sub folder " subfolder A " and within which is another subfolder " subfolder B " that contains my site Website B so the path looks like root/sublfolder_A/subfolder_B/ that contains my **Website B ( i.e subfolder_B) ** All goes fine.When i access the website B from my desktop/Laptop Website B is loaded normally. but when i access the Website through a mobile device , mobile site of Website A is loaded while as it should load website_B Also , to let you know , both websites have different URL's and not subdomain's or anything. What could be the problem ? htaccess of website B or website A ? or something else ? Here is the htaccess of my website B RewriteEngine On RewriteRule .* index.php [F] RewriteBase / RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteCond %{REQUEST_URI} /component/|(/[^.]*|\.(php|html?|feed|pdf|vcf|raw))$ [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php [L]

• WiFi on Ubuntu 12.04 custom: downloading unbearably slow

  - by Mark

  iwconfig reports 11 Mbps, yet I've seen as low as <1 KBps. This is the latest in my laundry list of Ubuntu problems in a dual-boot machine (cyberpowerpc custom, intel i7-3820, nvidia gtx 570). I received it two days ago, Windows 7 running fine, still having problems with Ubuntu. The browsing is intermittent but unacceptable. e.g. I could get to this site last night but I couldn't post this question. The downloading is unbearably slow, I can't download anything or install any packages because the speed is so slow. e.g. I am trying to install vim which is inexplicably missing from my 12.04 install (add another one to the problems list) and my download speed reported in the terminal was 241 B/s. Yes, bytes. iwconfig reports 11 Mbps, which further adds to the confusion. User@ubuntu:~$ iwconfig lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"linksys" Mode:Managed Frequency:2.437 GHz Access Point: 00:18:39:76:2C:A1 Bit Rate=11 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=36/70 Signal level=-74 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:54 Invalid misc:18 Missed beacon:0 eth0 no wireless extensions. Any ideas? I see this is a problem a lot of people, but none of the on line solutions have worked for me so far. e.g. one site recommends editing the ath9k.conf file in /etc/modprobe.d, yet this file isn't even in the folder: User@ubuntu:/$ cd etc/modprobe.d User@ubuntu:/etc/modprobe.d$ ls alsa-base.conf blacklist-oss.conf blacklist-ath_pci.conf blacklist-rare-network.conf blacklist.conf blacklist-watchdog.conf blacklist-firewire.conf dkms.conf blacklist-framebuffer.conf nvidia-current_hybrid.conf blacklist-modem.conf nvidia-graphics-drivers.conf I think the nvidia gpu might be mucking things up. I had the "blinking cursor" problem when installing in the first place, and then I had the monitor out of range problem as well. I have my faithful Asus laptop, which is running Ubuntu 12.04 just fine. The only difference is executing host -t SOA local in the terminal gives User@ubuntu:~$ host -t SOA local local has SOA record local. nobody.localhost. 42 86400 43200 604800 10800 in my new machine, and the command reports Host local. not found in the laptop. Help would be most welcome, as I am in danger of reverting back to Windows. I'm seriously considering it. Sorry for the length, trying to show my effort in resolving the issue and include terminal snippets that might be helpful.

• I cannot change the screen brightness

  - by user1793249

  here's my problem: Ever since I installed Ubuntu 12.10 on my computer I haven't been able to change the screen brightness, it was always set to the maximum. I did take a look at this post: Decrease Backlight Below Minimum And it helped me resolved the issue with the unbearable brightness, however one problem persists: I cannot change it through "Brightness & Lock" or the function buttons (F2 and F3), when I press the buttons, the animation shows up but nothing happens. I tried the following: http://www.refreshit.info/2012/08/solved-brightness-increase-and-decrease.html It did nothing... If it helps: I have an HP-dv6 6185la, it has an ATI Radeon 6770M HD card and an Intel HD Integrated Graphics Card It only detects the "Intel® Sandybridge Mobile" Thanks in advance.

• Fixing a broken toolbox (In Visual Studio 2010 SP1)

  - by mbcrump

  I was recently running into a situation where every time I opened Visual Studio 2010 SP1, the following message would appear for about 60 seconds or so: "Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage '{2C98B35-07DA-45F1-96A3-BE55D91C8D7A}'" After finally get fed up with the issue, I started researching it and decided that I’d share the steps that I took to resolve it below: I first made a complete backup of my registry. I then removed the following key: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}] I went to the following directory: C:\Users\Your Name Here\AppData\Local\Microsoft\VisualStudio\10.0\ and created a folder called bk and moved the .tbd files to that folder (they are hidden so you will have to show all files). I then removed the .tbd files in the root directory. I then launched Visual Studio 2010 SP1 again and it recreated those files and the problem was gone. Anyways, I hope this helps someone with a similar problem. I created this blog partially for myself but it is always nice to help my fellow developer.  Thanks for reading. Subscribe to my feed

• Steam not opening or responding at all

  - by user109409

  The steam client won't open nor does it display any error message. I have tried right click > Games. I ran steam steam://open/games command, but the client just does not respond. Removing it with apt-get remove steam, deleting the Steam directory & the .deb file and reinstalling it, did not work either. This problem only occurred after I used killall steam.sh to force quit it, it was working fine before. I'm running 12.10 on a 64bit laptop with no additional drivers installed. Anyone else have this problem and a possible workaround? Thank you

• What do I need to do when installing old version of ubuntu on new arch platform?

  - by Blangero

  I got a board with aptio cpu which is said to be of new platform and may have driver problems while using old version of ubuntu, and it do have. After installing my customized Live ubuntu server with X(the system runs as a liveCD), X starts but failed to get right resolution. If I run ubiquity in the live system to install the system to my disk, I can't start X and the whole console was a mess.Tried connect from ssh and upgrade, failed to solve the problem. Install ubuntu 12.04.2 desktop, at bootup the text was a mess, X starts and still could not get the right resolution. Install ubuntu 14.04 server, at bootup the text was also a mess, but it turned clear and the resolution is right. So what else do I need to provide? CPUInfo ? lspci -nn | grep VGA ? anything else? And what's the problem? What can I do to support the newest arch in my customized system? Thanks

• Why I can't open folders copied from Ubuntu on Windows?

  - by user37805

  Is not possible for me to open whatever folder I copy from Ubuntu to my Windows partition or whatever usb memory. Windows says the folder's location is either disconnected or doesn't exist. Can't copy, cut or delete the folder on Windows but with Ubuntu I can. This happens even if I create the folder on the ntfs disc. I have never had this problem before. Files are openable however, but not if they are inside a folder. This started after I haven't made any other changes except for the update to kernel 3.2.0-30-generic, I am using 12.04, never installed Samba, after this problem started I tried to fix it by installing ntfs-3f, ntfsprogs, ntfs-config, but It didn't work.

• Ubuntu13.10 64 bit installed alongside windows 7 32bit doesn't boot

  - by alone

  I have installed Ubuntu 64-bit alongside windows 7 32-bit. (Windows installed first.) The installation was successful, but when I restart it just goes directly to windows 7 without any sign of existence of Ubuntu. I'm a beginner who just wanted to get familiar with Ubuntu, but now I'm disappointed with it. Someone told me the not booting problem is related to EFI, but now I'm scared to play with this boot stuff because my information might be totally lost. How can I fix this boot problem and get to Ubuntu?

• Checking For Empty Enumerations

  While spelunking in some code recently I saw a method that looked something like this: public void Foo<T>(IEnumerable<T> items) { if(items == null || items.Count() == 0) { // Warn about emptiness } } This method accepts a generic enumeration and then proceeds to check if the enumeration is null or empty. Do you see the potential problem with this code? Ill give you a hint, its this line: items.Count() == 0 Whats the problem? Well that line right there has the potential...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Upgrade Ubuntu 12.04 to 12.10 failed

  - by pre-commit-hook

  I've a problem. Upgrade failed after "Setting new software channels", when Calculating changes. I tried error: Not all updates can be installed An unresolvable problem occurred while calculating the upgrade: E:Unable to correct problems, you have held broken packages. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. Now i have 1580 packages to update and do not update. Partial system upgrade also fails in the first step. What next? Alternatively, to undo the changes? Thank's to help.

• gtk_widget_grab_focus() jumping to next field automatically?

  - by Ravi Raj

  I am creating a 'C' project with glade and gtk. I want a focus on a gtkentry field naming txt_abc and so I called the function: gtk_widget_grab_focus (txt_abc); There is another gtkentry widget just after txt_abc widget naming txt_def. My problem is instead of getting focus on txt_abc widget, the cursor is automatically being focused on txt_def widget, when I am running the application. One more thing, when I am setting the focus at txt_def widget by calling the code: gtk_widget_grab_focus (txt_def); the control is again being focused on the next widget on the window, i.e. txt_name. I want the focus exactly on the widget I am setting the grab signal. How to resolve this problem.

• How to create a Request Specific Thread Safe Static int Counter?

  In one of my server application I have a class that look like, class A { static int _value = 0; void DoSomething() { // a request start here _value = 0; _value++; // a request end here } // This method can be called many time during request void SomeAsyncMethods() { _value++; } } The problem is SomeAsyncMethods is async. Can be called many times. What I need when a request start set _value = 0 and then asynchrosnously increment this. After end of request I need the total. But the problem is that another request at the same time can access the class.
