• Is it possible to use two different ErrorDocuments for different paths of a website?

  - by tapwater

  this is my first question on stackexchange and it might be a bit confusing. I currently run PmWiki (sorry, you'll have to google it, new user can only have 2 hyperlinks) at mydomain.com/pmwiki. I have a 404 page and .htaccess set up in my site's document root for 404 pages regarding anything that doesn't have to do with my wiki. By default, PmWiki handles URLs a little confusingly so I had to use this in order to get it to look like mydomain.com/pmwiki/Namespace/Page I had to create a .htaccess in /pmwiki to remove parts of the URL. PmWiki also has a custom 404 (Site/PageNotFound) page that has stopped working, now my site uses the /404.htm page. I noticed this when trying to install this "recipe" to enable case-insensitive URLs. Currently the only way to access Site/PageNotFound is by actually linking to it, and, if you read how that recipe seems to function, this is an issue. Currently mydomain.com/pmwiki/blahblah and mydomain.com/pmwiki/legitimate_namespace_but_lowercase/legitimate_lowercase_page_name both direct to mydomain.com/404.htm. I have to admit I'm very confused, and I apologize if I was unclear in any of this, but I could definitely use some help. Thanks!

• Ubuntu 12.04 fresh install wont boot up

  - by user147220

  im running ubuntu 12.04 and it refuses to boot up. the screen will come on for a second, the mosue will appear, then itll go black again all inside about 3 seconds. i let it just do that for a while and eventually a window popped up saying i had a display issue. I didn't have a mouse but there was a button saying "ok" at the bottom that i couldnt click on. i hit enter, got through that screen, now im looking at another that says "What would you like to do?" - run in low-graphics mode for just one session - reconfigure graphics - troubleshoot the error - exit to console login then two buttons, cancel, and ok. I dont have a mouse and its not letting me navigate between these options with tab. firstly, if i make it through these windows will it get me into the computer so i can try and fix whats going on? also, whats going on here? also, how can i click on these buttons without the use of tab or a mouse?

• Why are the prices for broadband bandwidth at data centers much higher than consumer/small business offerings?

  - by odemarken

  The prices for broadband bandwidth at data centers are sometimes as much as 10x higher than for a typical small business/consumer connection, at least where I live. Now, I understand those are two differend kind of products, but what exactly are the differences? Is it mainly because the bandwidth you get at a data center is guaranteed (CIR), while a consumer offer lists maximal bandwidth (EIR/MIR)? Or are there other factors as well? (Note: my previous, much more specific question on the same general topic was closed as not constructive. I tried to extract the core issue and present it in a way that can be answered objectively. If you feel that this question is still bad and should be closed, please care to comment and explain why.)

• Boot Linux from DOS (with loadlin.exe etc)

  - by dreamlax

  I have been using the latest version of loadlin.exe (version 1.6e). It works on some machines but on others I get "no place after kernel for initrd". The kernel is about 5MB in size (non-modular) and my initrd image (decompressed) is about 8MB. One route that I could take is to enable module support and offload some of the weight of the kernel into the initrd image but I'm not confident this will rectify the issue. Are there any alternatives to loadlin.exe that are capable of loading Linux from a booted DOS session? I basically have a series of DOS tools that I'd like to run one after another and then boot into Linux, which loadlin.exe seems to be working very well for except on some machines.

• One subdomain is not working

  - by BFTrick

  Hello there, My main domain works just fine - www.example.com and a subdomain set up by another developer works as well - sub1.example.com. But when I try to set another subdomain up I go through the process everything seems to work. The software creates the default files where the subdomain files should go. But when I try to browse there it doesn't work. My host uses Plesk to do all of the hosting stuff. What do you think the problem is? I doubt it is some sort of cache issue because I had problems on my phone which I tried after problems on the pc. Maybe for some reason Plesk needs time to set this up? I have used Cpanel before and that works instantly.

• How do I get `set show-all-if-ambiguous on` in my .inputrc to play nice with the Python interpreter?

  - by ysim

  I noticed that after I added the set show-all-if-ambiguous on line to my ~/.inputrc, whenever I pressed tab to indent a block, it would show me the bash Display all ... possibilities? (y or n) prompt, and leave me unable to indent the actual code. Is there any way to keep that line in my .inputrc but still have the tab key work as expected in the Python interpreter? This is in my VirtualBox Ubuntu 12.04 VM, if it matters. EDIT: Curiously, I now have a different issue with the Python shell that comes with Django -- when I press tab, I get Python tab completion, but only with one Tab press. I've opened a separate question here for it.

• 12.04 LTS Apache2 writing files from webpage at runtime has no effect - possible read/write permissions?

  - by J Green

  I'm running 12.04LTS with Apache and Mono in VirtualBox, with the goal of hosting a web app (coded in ASP.NET and C#) on my local network. The scripts on the page are able to successfully read from text files in the same directory as my site (/var/www/mysite/) but do not seem to be able to write. I'm sure the code works, because it did with my testing in Visual Web Developer on Windows. I don't get any errors, but when I click the button on the loaded webpage, the text file in question does not change. I'm fairly new to Linux in general, so I'm not too familiar with how to set permissions properly, and it may be a permissions issue. Unfortunately, I have searched all over the internet and haven't found a solution that worked, but I've tried (perhaps incorrectly) changing the owner of the files in question to www-root, changing the mode to a+rw, but sadly to no avail. I have tried everything here but it doesn't work: Whats the simplest way to edit and add files to "/var/www"? I hope someone can help me out.

• Allow PHP to write file without 777

  - by camerongray

  I am setting up a simple website on webspace provided by my university. I do not have database access so I am storing all the data in a flat file. The issue I am experiencing is related to file permissions. I need PHP to be able to read and write the data file but I don't really want to set the file to 777 as anybody else on the system could modify it, they already have read access to everyone's web directories. Does anyone have any ideas on how to accomplish this? Thanks in advance

• HTTP PHP Authentication and Android

  - by edc598

  I am working on a website for which I hope to have an application for as well. Because of this, I am creating PHP API's which will go into my Database and serve specific data based on the method/function called. I want to protect these API's from misuse however, and I plan on implementing Authentication Digest to do so. However one of the OS's I want to support is Android. And I know that a malicious user would be able to reverse engineer the Android app and figure out my authentication scheme. I am left wondering: 1. Is there a better way to protect these API's from misuse? 2. Is there a way to prevent a malicious user from reverse engineering the app and potentially seeing the source code for it, enabling them to see my authentication scheme? 3. If none of these are preventable, then is my only option to have a Username/Password cred specifically for the Android app, and when eventually hacked, change the creds and issue an update for the app? I apologize if this is not the place to post such a question. Still pretty new to StackOverflow. Thanks in advance for any insight, it would be quite helpful.

• Windows Phone 7 v. Windows 8 Metro &ldquo;Same but Different&rdquo;

  - by ryanabr

  I have been doing development on both the Windows Phone 7 and Windows 8 Metro style applications over the past month and have really been enjoying doing both. What is great is that Silverlight is used for both development platforms. What is frustrating is the "Same but Different" nature of both platforms. Many similar services and ways of doing things are available on both platforms, but the objects, namespaces, and ways of handling certain cases are different. I almost had a heart attack when I thought that XmlDocument had been removed from the new WinRT. I was relived (but a little annoyed)  when I found out that it had shifted from the "System.Xml" namespace to the "Windows.Data.Xml.Dom" namespace. In my opinion this is worse than deprecating and reintroducing it since there isn't the lead time to know that the change is coming, maker changes and adjust. I also think the breaks the compatibility that is advertised between the WinRT and .NET framework from a programming perspective, as the code base will have to be physically different if compiled for one platform versus the other. Which brings up another issue, the need for separate DLLs with for the different platforms that contain the same C# code behind them which seems like the beginning of a code maintenance headache. Historically, I have kept source files "co-located" with the projects that they are compiled into. After doing some research, I think I will end up keeping "common" files that need to be compiled in to DLLs for the different platforms in a seperate location in TFS, not directly included in any one Visual Studio project, but added as links in the project that would get compiled into the windows 7 phone, or Windows 8. This will work fine, except for the case where dependencies don't line up for each platform as described above, but will work fine for base classes that do the raw work at the most basic programming level.

• Poor disk performance with high disk capacity usage

  - by GoldenNewby

  I've heard numerous times in the web hosting industry that using "too much" disk space on a drive is bad for performance. Is this just a myth? Can someone explain why this is an issue, even in a situation where the amount of IO done to the drive would be the same at 10% as it would be at 90%? I'm especially curious in the case of virtual servers. If I set up 10 Logical volumes as the virtual disks for some VMs, is it going to run better if I "waste" 20% of the disk space?

• Mouse pointer size inconsistent

  - by charon00

  Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

• How do I fully clear Firefox's cache of CSS and JS files?

  - by Mike Webb

  I work on a website at my work. The issue is that if I visit the site, which uses the cached versions of the CSS and JS files, and then upload an updated copy of a CSS/JS file, Firefox will still use the cached version. I can go to 'Tools-Clear Recent History' and clear the Cache of "Everything" and it still uses the cached version of the files. It will eventually updated and use the new files, but it can takes hours for this change to occur. So, how do I completely clear Firefox's cache of these files?

• Windows XP crashes by GT610 driver (nv4_disp)

  - by undone

  I have a PC which was working fine but one day screen went dark and nothing was shown. I thought the problem is graphic card, so I replaced it with new one. I bought a new graphic card (GeForce 610) and installed it on my system. I formatted my hard-drive and installed a fresh Windows XpSp3 and its drivers. Everything was fine but after installing graphic card's driver, I got an error saying windows got stuck in an infinite loop and it couldn't get out (in nv4_disp). I uninstalled it and downloaded its last version and installed it. Unfortunately, I got the same error and windows restated! Here's my system: Pascal Motherboard PT880PRO Intel CPU Windows XPSp3 I searched this issue on the internet and I found bunch of suggestions (from cleaning hardware to installing latest version of its driver) but nothing help! Any help would be appreciated! Thanks.

• How get OSX Lion to save Modifier Key Settings (i.e. swap Ctrl and Cmd)

  - by Huliax

  I use Lion at work with an MS Natural Ergonomic Keyboard 4000. Every single time I log in I have to go into settings and swap the command and control keys. This is really annoying. Is there a way to get these settings to stick? Beyond that, I'd also like to remap a few other keys and I'm interested in tools for doing that. I think I need to work out the first issue first though. Thanks for any help.

• Can most Intel processors run 64-bit Windows 7?

  - by Jian Lin

  Can most Intel processors run 64-bit Windows 7? Such as all the i7, i5, Core 2 Duo, Dual Core, Single Core with HT, and even just Single Core? I think a popular view is that if you can run 64-bit Windows 7, then use it? It might have driver compatibility issue but if there is no device hooked up, then there is no problem? What about some software / games not compatible with the 64-bit version or may run slower? thanks. update: a couple of my machines have 4GB RAM. so 64-bit Win 7 can make use of the full 4GB RAM instead of only about 3.2GB

• Relating ping to perceived browser GUI response

  - by cvsdave

  We periodically get complaints of poor GUI (browser page) response that we need to explore. I am looking for a quick and cheap first check to see if the issue is network latency, or server performance. Has anyone encountered any discussion of ping time and perceived GUI response? I understand that GUI response is complicated, but it would be nice if we could find or develop a rule of thumb along the lines of "Hmmmm, ping is over 200, it might be network problems". Ideally, this lives in a script on the user's machine so that we can see the latency that they are seeing... (BASH, Linux). A reference to a good discussion page would be a fine answer, as would any recommendation of other source material.

• Kernel compiling with -j2+ parameter ends prematurely with no error message or output bzImage

  - by Minix

  I've noticed quite a while ago that compiling a kernel with the parameter -j set to 1 or more doesn't produce a bzImage. Instead, it ends prematurely without any advice. I have reproduced the same behavior in both my netbook and home server. As far as I'm aware, the point where the compilation stops is random - Compiling twice with the same parameters will probably stop at different files. However, when I run make with no -j* parameter the compilation ends just fine and outputs a working bzImage. Both machines run Intel Atom (N270 on the netbook and 330 on the server) and I've compiled for these processors. If I recall correctly, I've tried compiling both with Atom and with generic x86_64 options. The kernel version I'm building is 2.6.34.1 I've always compiled normally with those options in my Core2Duo and Pentium Dual Core machines. Has anyone experienced this issue? Any ideas why does this happens? Is there a fix or workaround?

• Unable to read USB External HD after aborted back up

  - by Stjepan

  I have two PC laptops. On one of the two PC's (Win 7) I Aborted a back up and ejected the drive. Now that same pc wants to format the drive. I plugged the drive into the other pc (Win XP) and that one reads the drive and all data stored. Why does one want to format the drive and the other does not? .... My apologies for not being clearer with my original question and thanks for the responses, so; The drive is not a flash stick, its an external WD Hard drive plugged in via the USB. The two tips provided did not resolve the issue. Strangely, the pc with win XP can read the drive but the pc that the HD was plugged into when the backup was aborted still wants to format the drive.

• No image from graphics card but image from onboard video

  - by ReAzem

  I have an HD 5970 running on a P8Z68-v LE motherboard and I have no image comming out of the graphic card. When I plug my screen on my motherboard, I see the bios and the OS. When I plug my screen on the graphic card, I don't see anything. I know that the graphic card works because I have tested it on another computer. I know the motherboard works because I tested it with another graphic card and it worked. I know that the graphic card works with the computer because I have another computer with a P8Z68-LE and an HD 5970. I know it is not an OS issue because I should atleast be able to see the bios. I have tried unplugging my HDDs so that the OS dont interfere with anything. Using a 1000W power supply Using another HD5970 on the computer works. So this is a problem with my HD5970, but why is the graphic card working on my other computer?

• Cannot install Java 7 update 9 32-bit on Win 7 64

  - by J. Parrino

  As there were several versons of Java on my laptop, I decided to uninstall them all and reinstall only the current version. I uninstalled all 64-bit and 32-bit versions using Revo Uninstaller. After dowloading the current versions, when attempting to install them, I get a message that both the 64-bit and 32-bit versions cannot be installed as they are already installed. Both the Windows 7 Programs and Features and Revo show no Java installed at al. I then tried the Microsoft Fixit for install and uninstall issues (KB 2438651). I was then able to install the 64-bit version, but continued to have the issue with the 32-bit version. I ran CCleaner, Glary Utilities and Auslogics Registry Cleaner, and noticed Java keys that were to be uninstalled. After cleaning the registry, I attemped to install the 32-bit version of Java once more, to no avail. Any suggestions on how to rectify this problem? Thank you for any guidance you can provide.

• Access Windows VPN DNS from Ubuntu

  - by user46427

  I am using Ubuntu 10.04 to access a Windows VPN. I connect to the VPN from Ubuntu, and when I open a Windows 7 virtual machine (VirtualBox), everything works great ... I can access local network drives, ping local servers, remote into local machines, etc. However, I can do none of this from Ubuntu. With the VPN connected, I cannot even ping anything within the VPN local network. I'm guessing it's a DNS issue that Windows is handling automatically but Ubuntu needs a setting somewhere to tell it to use the DNS servers of the VPN network? Any ideas? I'm a relative novice to Ubuntu, esp. VPN in Ubuntu. [EDIT] Actually, I'm almost positive it is DNS, because if I get the IP address from the Windows VM I can use Terminal Server Client to remote into a machine.

• JCP.Next.3 working group meetings have begun

  - by Heather VanCura

  As mentioned in the blog earlier this week, the third JSR in the JCP.Next effort, JSR 358, A major revision of the Java Community Process, was approved by the JCP EC to continue development earlier this year.  This JSR will modify the Java Specification Participation Agreement (JSPA) as well as the Process Document, and will tackle a large number of complex issues, many of them postponed from JSR 348. For these reasons, the JCP EC (acting as the Expert Group for this JSR), expects to spend a considerable amount of time working on this JSR. The JSPA is defined by the JCP as "a one-year, renewable agreement between the Member and Oracle. The success of the Java community depends upon an open and transparent JCP program. The first EG working meetings have started and  meeting materials and minutes are available on their Java.net project. Last week an IP Working Group commenced and their meeting minutes and materials will also be available in this location; they anticipate meeting on a weekly basis moving forward.  Also see the JSR 358 issue tracker on java.net.  Right now there are 45 issues being discussed.  Join the JSR 358 java.net project to keep up to date on the latest developments.

• Cannot SSH into Virtual Machine

  - by MasterGberry

  I am running a CentOS VM on my desktop that I use for development testing when coding in python. At my school I have a dedicated IP setup for the VM and my desktop so I never seem to have an issue ssh'ing from desktop into VM. I am now at home for winter break and cannot seem to SSH into the VM using the local ip address behind my router, the external IP with port 22 forwarded to my VM, or anything. Strangely enough I can ssh into my production server and then fromt here ssh into the VM, but not from my desktop to the VM directly What should I do to get this to work? Thanks
