• xkb layouts not working (in KDE?) after upgrade from Ubuntu 9.10 to 10.04

  - by Alan

  I customised my keyboard layout in 9.10 by editing the appropriate /usr/share/X11/xkb/symbols/ file. After upgrading to 10.04 I noticed it had overwritten all my modifications, so I recovered the layout and overwrote the symbol file's base entry. Sadly KDE (and, presumably, the entire OS) seems to ignore the files altogether. The help files don't mention anything about modifying layouts anyway (and the layout switcher seems to be using setxkbmap, which uses the above path according to its man page), so I'm at a bit of a loss. Do I need to compile this into some other format somehow or how do I get it to work?

• taskbar-free window manager

  - by 7vies

  I'm looking for a window manager that is not based on the "standard" taskbar (which I find a poor idea and I'm completely tired of). I'm aware of tiling window managers and improvements in last versions of operating systems, but I can't find what I need. I suppose that any window takes the whole screen (or can be tiled), and I imagine switching between windows like that: on a hotkey or mouse hot zone the screen becomes a task switcher where tasks are organized in a somewhat convenient manner. Well, it's a bit like a taskbar with autohide, but I think there could be some more convenient ideas than simply stacking icons and descriptions... It is also supposed to be lightweight enough, for example to run on a netbook. Any suggestions?

• How can we control the device driver load order in Windows XP ?

  - by Deniz

  We are trying to install both an HP scanner and a Kodak scanner on an XP machine and the problem is that that HP's scanner driver always places itself into the first and default scanner device position. We are using an automation software on that machine which must use the Kodak scanner as the default scanner. The HP flatbed isn't needed to be the default scanner on that machine. It will always be used manually and through its own software. Our developers did some research 2 years ago couldn't find a solution. Nowadays we are preparing to expand our user base and this problem did surface again on machines with the same configuration. I did a more aggresive search pn the net and found some tips like this one : http://support.microsoft.com/kb/115486 I couldn't realize how to suit this solution to my scenario. Could someone please point me to the right direction ?

• Software for formatting / web-publishing tutorial-type, technical articles

  - by gojira

  I want to put some of my own technical writing on the web: tutorials, how-to's, conceptual articles about programming etc. I write mostly for myself yet, but think others can benefit from it so I want to put it online, and I also have plans of making everything more coherent and turning it into a book. My articles are not meant as a blog, they're just meant as a collection of tutorials and how-to's, but I think a blog-type software would probably be the most appropriate mode of formatting that kind of stuff. Right now I am using the blog feature of cite u like, which is very low tech and I really need something better. On my wish list is, among other things: code snippets in scrollable boxes syntax highlighting for source code snippets tagging articles with graphical icons according to topic, like in slashdot of course users (i.e. readers) should be able to comment on articles Also, just more options than a super-simple blog should look slick! should not look wikipedia-like Is there any software you can recommend for this purpose?

• Minimum space required for Server 2008 R1 install?

  - by Chris J

  I'm trying to plan disk space for a virtual environment, and wanting to keep virtual disks as small as possible - mostly as apart from the base OS, the software going onto the VM is less than a few MB, so want to avoid physical disk space going to waste; plus it'll give me an idea of how many VMs I could physically fit in {x}GB of physical drive. For Server 2003, I've had installs on 2GB and 5GB sized virtual disks. However for Server 2008, Microsoft recommends a minimum of 10GB (I assume this is both for x32 and x64). For the record, I will be installing the x32 version. Now I know I could just go ahead and try a small install, but wanted to solicit any practical knowledge as well :-) What's the smallest install of Server 2008 possible? (excluding server core installations).

• Download acceleration with jigdo?

  - by james

  Im using jigdo-lite to download a Debian DVD ISO. I already have the CD version of the image, so I added the CD files to the task. Now I need to download many files (not all) of the DVD ISO. The default jigdo-lite uses wget to download files. It seems jigdo (wget) downloads only one file at a time with one connection. So I'm getting a low download speed. How can I accelerate the download speed using jigdo? Possible Solutions: Using different download manager with jigdo. Is it possible? If yes, How? Using jigdo (wget) to download multiple files at once. How? Getting download links of remaining files to download so that they can be downloaded with a download manager and later added to jigdo iso. How?

• Virtual Desktop Provisioning - Vmware View 5.2 Maintenance Questions

  - by Lee J. DeAngelis

  Currently running an environment of about 400 VMware View 5.2 virtual Desktops. The environment runs pretty efficiently but we sometimes run into problems with certain pools from time to time. Just recently we had a pool that was causing high write latency when users logged in. It just happened all of a sudden and had been working fine for weeks. On a hunch we completely broke down the pool and re-provisioned it from a new image. This corrected the problem. In fact every real issue we've had so far was fixed by a recompose or complete break down and re-provisioning of one pool or another.Our environment consists of Cisco UCS and Netapp 3240s using flashcache running VMware View 5.2. My questions are: What are some maintenance best practices other VDI admins are using? How often are you recomposing? rebalancing? re-provisioning? How long should you keep base image snapshots around?

• sending mail using mutt + emacs

  - by lakshmipathi

  How to sent mail from emacs? I have add from address and subject and trapped inside emacs I found this There are two ways to send the message. C-c C-s (mail-send) sends the message and marks the mail buffer unmodified, but leaves that buffer selected so that you can modify the message (perhaps with new recipients) and send it again. C-c C-c (mail-send-and-exit) sends and then deletes the window or switches to another buffer But both ( ctrl+c ctrl+s ) and (ctrl-c crtl+c) are not working ps:Thought it's not programming related. it's programmer environment related question-hoping it won't be closed :)

• Brand new Lenovo u410 heats up around touchpad

  - by Ali

  My Lenovo u410 started heating around the right palm rest minutes after I unpacked it! I am devastated, because I bought this for programming, and it's impossible to type on this for extended periods with the surface getting so hot. I haven't run any serious programs on it yet, so the processor has been pretty much idle. I've been Googling this problem, and found only one person who had this issue too. Is this is a defect in the product? Why aren't many others getting this problem? I bought it via newegg.com and as per their policy you can't return a product once you've opened it. Specs: Core i5, 6 GB RAM, 750 GB harddisk. Running Windows 8.

• Laptop burned after heavy OpenGL usage. Is there hope?

  - by leladax

  After programming for OpenGL and a 'slow OS' case for a couple of minutes the screen went blank. I shut it down with forcing it with the shutdown key and now there's no led at all with battery or AC, it doesn't start at all, it's totally dead. It's most certainly not the AC adapter since that didn't show at first, it doesn't start a led at all and if the AC is connected it does a very slight and faint clicking noise (one has to have his ear next to it to hear it, near the AC connector). Is there any hope? I suppose it's a burned motherboard. I suspected a burned GPU but that would still leave the leds at least lid or at least attempting to start up. Now it's totally dead. It's a TOSHIBA satellite x200-219. It has no warranty, as it's more than 2 years since purchase.

• Replication from OSX OpenDirectory to OpenLDAP

  - by natacado

  I have an OpenDirectory server running on an OSX Server machine, and I'd like to increase the reliability of the service by having a slave server. The problem is, I only have 1 OSX Server but I have plenty of Linux servers available. I'm happy with Apple's tools that integrate with OpenDirectory, but given Apple's recent discontinuation of the XServe, I'm not particularly interested in continuing with Apple hardware. I remember hearing that OpenDirectory is (now-distantly) based off the OpenLDAP code base; is there any way I could replicate from OpenDirectory to OpenLDAP instead of having to purchase another OSX server?

• Org-mode lags in highlighting source

  - by quanticle

  I'm using org-mode to maintain my programming notes. This means I have lots of source code blocks, as follows. #+begin_src <language name> <code> #+end_src One thing I've noticed is that when I write the #+end_src, emacs doesn't color the source code as such. Yet, if I quit emacs and reopen the notes file (or force a refresh with the Org-Refresh/Reload-Refresh setup current buffer menu entry) the source is colored grey if I'm using the GUI or green if I'm using emacs in the terminal. Is this an inherent limitation of emacs, or am I doing something wrong in setting up my code blocks that's preventing emacs from going back and recoloring the source code that I've entered?

• What options do I have for creating customized keyboard shortcuts?

  - by Moses

  As I am getting more heavily into programming as a job and no longer as a hobby, I am definitely in need of some ways to improve my productivity. One thing that would definitely help in that respect is being able to create customized keyboard shortcuts for text/code snippets. For instance, holding down CMD+L+O+R+E+M will output a paragraph or two of the Lorem ipsum filler text, or CMD+F+U creates a function declaration. What I am ideally looking for is a database where I can store formatted text snippets, bind them to my choice of keystrokes, and then have the text paste whenever I perform the associated keystrokes. Are there any stand-alone applications that can do this for a Mac. Also, are there any text editors / IDEs that have this ability built in?

• Connecting FreeNAS 8 to Mac OS X Lion LDAP Server

  - by Absolution

  I currently have Mac OS X Lion Server running from a MacMini and want to use it purely as an LDAP server for authentication for FreeNAS 8. I have FreeNAS setup and running on a VM, all features working correctly and as expected however I cannot connect to my LDAP server (MacMini). Error message; **Nss_ldap: could not search LDAP server – server is unavailable** For LDAP service settings in FreeNAS, I know my Hostname and Base DN are correct (exact copies of what I set originally and ones that are shown in server:open directory overview) however I am unsure what to enter for Root bind DN, password and Suffix’s. I have researched into where I can find these out and other than following the FreeNAS examples it appears there is a way to find out within the Server Workgroup Manager specific to my settings – however this function is unavailable to me and cannot be ‘ticked’ to view for some strange reason. Some forums explain how Root bind DN should be uid=admin, dc=… and others cn=admin, dc=… – I’m rather confused and would appreciate your help or advice with this.

• How to create a password-less service account in AD?

  - by Andrew White

  Is it possible to create domain accounts that can only be accessed via a domain administrator or similar access? The goal is to create domain users that have certain network access based on their task but these users are only meant for automated jobs. As such, they don't need passwords and a domain admin can always do a run-as to drop down to the correct user to run the job. No password means no chance of someone guessing it or it being written down or lost. This may belong on SuperUser ServerFault but I am going to try here first since it's on the fuzzy border to me. I am also open to constructive alternatives.

• Automatic storing package before installing it on .deb based system?

  - by macias

  The reason I am asking this question is I am concerned about simple rollback (I already read how to find out what packages were installed). So I would like to set global (per entire system) option, that forces system to store each package before installing/updating it. With such workflow, I could update whatever I want, and if for example the newest version of Dolphin would be worse than previous one I could simply go to directory with stored packages and install previous version instead (the previous version is either base version -- on ISO -- or version from previous update). Is there such feature as global option to automatically store each package before install? It have to be guaranteed that no package is updated on-fly, i.e. without being stored before. I am learning LMDE, but answer for any .deb based system would be fine -- Ubuntu, Debian, you name it.

• 8-bit game creator software

  - by dag729

  Hi, Anyone knows about some 8-bit game creator software that runs under GNU/Linux? I want to make some funny game in my spare time, but I prefer to have a tool (or a set of tools) that will help to keep it just a spare-time-project, thus not involving programming! :D Thanks in advance EDIT: For instance, some month ago I tried FPS Creator, being a frontend of DarkGame Studio. Well, FPS Creator is for a 3D FPS game: what I meant is a software similar to this one, but concening 8-bit'ish game.

• Automatically delete old files from a specified folder?

  - by davr

  I want to set up an automatic task that will automatically delete files older than X days from a specific folder. I'd prefer to do it without having to install any 3rd party software, but I'll be ok if it's a very small and simple utility. I want this to force me to keep my files organized. I am setting my browser to download to a standard folder, and then with this script to automatically delete files older than a week, I will be forced to move & organize downloaded files I want to keep.

• Modifying a gedit syntax highlighting file

  - by Oscar Saleta Reig

  I am trying to change a highlighting file from Gedit. I have modified the file /usr/share/gtksourceview-3.0/language-specs/fortran.lang because I want to change the cases in which the editor takes a statement as a comment. The problem I have is that when I choose the new highlighting scheme nothing highlights, it just remains as plain text. The file fortran.lang was opened with su permissions and I just copy-pasted everything into a new Gedit file and later saved it as fortran_enhanced.lang in the same folder. The changes I've done to the original file are these: Original fortran.lang file: <language id="fortran" _name="Fortran 95" version="2.0" _section="Sources"> <metadata> <property name="mimetypes">text/x-fortran</property> <property name="globs">*.f;*.f90;*.f95;*.for</property> <property name="line-comment-start">!</property> </metadata> <styles> <style id="comment" _name="Comment" map-to="def:comment"/> <style id="floating-point" _name="Floating Point" map-to="def:floating-point"/> <style id="keyword" _name="Keyword" map-to="def:keyword"/> <style id="intrinsic" _name="Intrinsic function" map-to="def:builtin"/> <style id="boz-literal" _name="BOZ Literal" map-to="def:base-n-integer"/> <style id="decimal" _name="Decimal" map-to="def:decimal"/> <style id="type" _name="Data Type" map-to="def:type"/> </styles> <default-regex-options case-sensitive="false"/> <definitions> <!-- Note: contains an hack to avoid considering ^COMMON a comment --> <context id="line-comment" style-ref="comment" end-at-line-end="true" class="comment" class-disabled="no-spell-check"> <start>!|(^[Cc](\b|[^OoAaYy]))</start> <include> <context ref="def:escape"/> <context ref="def:in-line-comment"/> </include> </context> (...) Modified fortran_enhanced.lang file: <!-- Note: changed language id and name --> <language id="fortran_enhanced" _name="Fortran 95 2.0" version="2.0" _section="Sources"> <metadata> <property name="mimetypes">text/x-fortran</property> <!-- Note: removed *.f and *.for from file extensions --> <property name="globs">*.f90;*.f95;</property> <property name="line-comment-start">!</property> </metadata> <styles> <style id="comment" _name="Comment" map-to="def:comment"/> <style id="floating-point" _name="Floating Point" map-to="def:floating-point"/> <style id="keyword" _name="Keyword" map-to="def:keyword"/> <style id="intrinsic" _name="Intrinsic function" map-to="def:builtin"/> <style id="boz-literal" _name="BOZ Literal" map-to="def:base-n-integer"/> <style id="decimal" _name="Decimal" map-to="def:decimal"/> <style id="type" _name="Data Type" map-to="def:type"/> </styles> <default-regex-options case-sensitive="false"/> <definitions> <!-- Note: I want comments only beginning with !, not C --> <context id="line-comment" style-ref="comment" end-at-line-end="true" class="comment" class-disabled="no-spell-check"> <start>!</start> <include> <context ref="def:escape"/> <context ref="def:in-line-comment"/> </include> </context> (...) I have read this question [ Custom gedit Syntax Highlighting for Dummies? ] and I tried to make the new fortran_enhanced.lang file readable with $ cd /usr/share/gtksourceview-3.0/language-specs $ sudo chmod 0644 fortran_enhanced.lang but it doesn't seem that made some difference. I have to say that I have never done a thing like this before and I don't even understand most of the language file, so I am open to every criticism, as I have been guided purely by intuition. Thank you in advanced!

• Media Sharing on Windows Server 2008 R2

  - by HCL

  I want a Server 2008R2 (x64) to act as DNLA-Server. I remember I tried this with a Server 2008 about two years ago and this was only possible with some ugly hacks. Is it on Server 2008R2 now possible to enable Windows MediaPlayer Media-Sharing by installing the desktop experience packet? Has someone already experience on this. Or is there another possibility to allow media sharing on a Server 2008R2 "the designated way"? I remember that on Server 2008 the way was to install the old MediaConnect-Pacakge. But I hesitate to install such a component on a server. Anciently I installed VirtualServer with Vista and enabled the media server there in, but this seems to me somewhat overkill for such a simple task.

• Eclipse: would more CPU cores with HyperThreading help increase speed?

  - by Dylan

  I'm programming a very large project in Eclipse. Right now I use a dual core machine with 2GB RAM, but Eclipse is sometimes busy for minutes (refreshing/indexing/building), so I'm upgrading to a new machine (with 16GB RAM and an SSD). Now I must choose between an Intel 2500K or an Intel 2600K that has HyperThreading. The price difference is about $100. Would that be worth it, for Eclipse, or is more memory/faster drive much more important for Eclipse ? Can Eclipse make use of the HyperThreading at all?

• Ubuntu 11.04 and OpenLDAP - where is the config?

  - by Tom SKelley

  I've been asked to setup a multimaster LDAP environment on Ubuntu 11.04 - instead of a single master server. I cloned the master server and recreated it into two VMs. I am trying to follow the instructions on the OpenLDAP documentation here: http://www.openldap.org/doc/admin24/replication.html and it talks about modifying the cn=config tree within LDAP. The subdirectory tree appears to be there at: /etc/ldap/slapd.d/ and a slapcat -b cn=config drops out a load of config information. When I try to connect using a browser and the admin bind credentials: ldapsearch -D '<adminDN>' -w <password> -b 'cn=config' I get: # extended LDIF # # LDAPv3 # base <> (default) with scope subtree # filter: (objectclass=*) # requesting: ALL # # search result search: 2 result: 32 No such object I don't see the config context when I connect via an LDAP browser either. I'm sure I'm missing something, but I can't see what it is!
