• xmonad keyboard doesn't work

  - by Mikkel Paulson

  I'm experimenting with xmonad, which I installed from the Ubuntu Software Centre on Ubuntu 12.10. It looks cool, but when I invoke it (using xmonad --replace from the command line) my title bars disappear and my keyboard stops working. At all. The terminal stops working, the keystrokes I've seen in online "getting started" guides are ignored, and the only way for me to actually power the system off is to hit the reset button or ssh in from my phone. Ironically, my mouse still works. One guide I saw suggested replacing the default window environment with xmonad, but I'm afraid of rendering my system completely inoperable if I do that. Any suggestions?

• Internal and external API architecture

  - by Tacomanator

  The company I work for maintains a successful SaaS product that grew "organically" over the years. We are planning to expand the line with a suite of new products that will share data with the existing product. To support this, we are looking to consolidate business logic into a single place: a web service layer. The WS layer will be used by: The web applications A tool to import data A tool to integrate with other client software (not an API per se) We also want to create an API that can be used by our customers that are capable of using it to create their own integrations. We are struggling with the following question: Should the internal API (aka the WS layer) and the external API be one in the same, with security and permission settings to control what can be done by who, or should they be two separate applications where the external API just calls the internal API like any other application? So far in our debate it seems that separating them may be more secure, but will add overhead. What have others done in a similar situation?

• What counts as an IDE?

  - by Matt Ellen

  Recently reading the question What languages do you use without an IDE? One question asked in a few answers was "is Notepad++ and IDE?" One answers to the original question said "None, I use vim...", implying that vim is an IDE. But then another answer suggested vim isn't an IDE. So where is the line? What about notepad, ed, or nano? Is the only non-IDE coding technique the butterfly technique?

• How to prevent a 404 Error when installing a subdomain using a wordpress multi-site installation

  - by Chris

  I have installed a multi-site instillation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.domain.com or http://subdomain.domain.com. However when I enter www.subdomain.domain.com or http://www.subdomain.domain.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.

• Projectiles in tile mapped turn-based tactics game?

  - by Petteri Hietavirta

  I am planning to make a Laser Squad clone and I think I have most of the aspects covered. But the major headache is the projectiles shot/thrown. The easy way would be to figure out the probability of hit and just mark miss/hit. But I want to be able to have the projectile to hit something eventually (collateral damage!). Currently everything is flat 2D tile map and there would be full (wall, door) and half height (desk, chair, window) obstacles. My idea is to draw an imaginary line from the shooter to the target and add some horizontal&vertical error based on the player skills. Then I would trace the modified path until it hits something. This is basically what the original Laser Squad seems to do. Can you recommend any algorithms or other approaches for this?

• After executing a command in the terminal, I sometimes can't execute another

  - by jreed121

  First off sorry for the noob question, I'm sure it's been asked before but I have no idea how to phrase it eloquently... Sometimes when I open/run/execute (unsure of proper term) an application (?lol) from the terminal like geany ie: geany filename.php or maybe run a node.js script: node server.js The command will execute fine, but I'm then left without the ability to execute any other commands unless I open another terminal. my root@pcname:~$ is gone and when I try typing in something else and hitting Enter it just breaks to the next line. I've noticed that sometimes I can hit CTRL+D and it'll give me my prompt back (sorry is prompt even the right name for it?) So could someone please explain why this is happening and how I can get back to the prompt without opening another terminal. Thanks, and sorry again for my noobery.

• Uninstalling GRUB from MacBook Air

  - by James Brooke

  So... I have a MacBook Air and I recently tried to install Ubuntu on my external HD. I booted Ubuntu from a flash drive and everything had gone fine. I turned off my computer and when I turned it on again I got a message of error and a "grub rescue" line to enter some code. I rebooted holding the "option" key and I selected the Mac partition and everything is fine with my system, but every time I start my system and I don't hold the "option" key, I get the same error and the grub rescue message. I just want things to go back to normal, as they were before I installed Ubuntu on my external HD (which, btw, presented a message that said there was no boot loader). What do I do?

• How to make xlock use the first key I hit as a part of my password

  - by alesplin

  I just switched from Arch Linux to Ubuntu 10.10. I'm running the Fluxbox window manager, and I use xlockmore to lock my screen with the following key shortcut: 192 :Exec xlock-mode marquee +usefirst -icongeometry 240x240 -message "back in a minute..." The problem I'm having is that xlock is definitely not using my first key as part of my password. Instead, it uses some randomized fade pattern to fade to the password screen. I find this highly annoying, as when I get back to my desk and start entering my password it doesn't register password characters until the fade pattern is complete. I've also tried the following modifications with no difference: 192 :Exec xlock -mode marquee -usefirst -icongeometry 240x240 -message "back in a minute..." 192 :Exec xlock -mode marquee -icongeometry 240x240 -message "back in a minute..." The first example worked flawlessly on Arch. Does Ubuntu have some sort of system default that you can't override on the command-line?

• 2D vector graphic html5 framework

  - by Yury

  I trying to find html5 game framework by following criteria: 1)Real good performance. 2)Good support of vector graphic( objects which contains canvas elements -line, rec,bezierCurve etc.) 3)Easy port to mobile. Optional- Physics Engine. I found 1)Pixi.js- it looks like real good, but i didn't find any info about "vector objects" support. 2) i found "vector objects" support in paper.js I need something like these: http://paperjs.org/examples/chain/ and http://paperjs.org/examples/path-intersections/. But it looks like paper.js- not so good performance as pixi.js. And it is not game engine. Is there any good framework meets these requirements? P.S. I found similar question here Which free HTML5-based game engine meets these requirements?. But it was a long time ago. A lot of new things were created since 2011.

• 12.04 - how to install alsa 1.0.27, to resolve dell sound card microphone echo issue to local speaker?

  - by YumYumYum

  Problem: Microphone in or Line in microphone audio is instantly captured and sinked to the local speaker, cause horrible echo problem About my system: (NO PulseAudio used (cause its always crash and unstable for my system/hardware, so auto killed and never used) I have ALSA 1.0.25 version running in Ubuntu 12.04 / 64-bit, with random kernel installed: kernel 3.5.0-17-generic kernel 3.8.x kernel 3.11.x But the echo problem is not resolved after trying all kernel. So, last option left now is to use ALSA 1.0.27 to see if that solves the problem. Is there any away to use ALSA 1.0.27 from any PPA to install in the Ubuntu 12.04? (without making it from source, to avoid breaking other packages and dependencies)

• How to implement soft edge areas with particles

  - by OpherV

  My game is created using Phaser, but the question itself is engine-agnostic. In my game I have several environments, essentially polygonal areas that player characters can move into and be affected by. For example ice, fire, poison etc' The graphic element of these areas is the color filled polygon area itself, and particles of the suitable type (in this example ice shards). This is how I'm currently implementing this - with a polygon mask covering a tilesprite with the particle pattern: The hard edge looks bad. I'd like to improve by doing two things: 1. Making the polygon fill area to have a soft edge, and blend into the background. 2. Have some of the shards go out of the polygon area, so that they are not cut in the middle and the area doesn't have a straight line for example (mockup): I think 1 can be achieved with blurring the polygon, but I'm not sure how to go about with 2. How would you go about implementing this?

  I have QtCreator 2.4.1 (Qt 4.7.4) installed on Ubuntu 12.04 LTS x86. When I try to change UI - drag-and-drop any widget (buttons, label, etc.) it won't let me do it, like it's read-only. The icon when I drag is a circle with a line through it. I've found that problem in Unity and it's suggested to install Gnome3 shell - Can't edit/drag-and-drop widgets in QtCreator I tried to install Gnome3 and it works fine as expected. But the question, is there any other way to work proper with QtCreator in Unity?

• Migrating Virtual Iron guest to Oracle VM 3.x

  - by scoter

  As stated on the official site, Oracle in 2009, acquired a provider of server virtualization management software named Virtual Iron; you can find all the acquisition details at this link. Into the FAQ on the official site you can also view that, for the future, Oracle plans to fully integrate Virtual Iron technology into Oracle VM products, and any enhancements will be delivered as a part of the combined solution; this is what is going on with Oracle VM 3.x. So, customers started asking us to migrate Virtual Iron guests to Oracle VM. IMPORTANT: This procedure needs a dedicated OVM-Server with no-guests running on top; be careful while execute this procedure on production environments. In these little steps you will find how-to migrate, as fast as possible, your guests between VI ( Virtual Iron ) and Oracle VM; keep in mind that OracleVM has a built-in P2V utility ( Official Documentation )  that you can use to migrate guests between VI and Oracle VM. Concepts: VI repositories.  On VI we have the same "repository" concept as in Oracle VM; the difference between these two products is that VI use a raw-lun as repository ( instead of using ocfs2 and its capabilities, like ref-links ). The VI "raw-lun" repository, with a pure operating-system perspective, may be presented as in this picture: Infact on this "raw-lun" VI create an LVM2 volume-group. The VI "raw-lun" repository, with an hypervisor perspective, may be presented as in this picture: So, the relationships are: LVM2-Volume-Group <-> VI Repository LVM2-Logical-Volume <-> VI guest virtual-disk The first step is to present the VI repository ( raw-lun ) to your dedicated OVM-Server. Prepare dedicated OVM-Server On the OVM-Server ( OVS ) you need to discover new lun and, after that, discover volume-group and logical-volumes containted in VI repository; due to default OVS configuration you need to edit lvm2 configuration file: /etc/lvm/lvm.conf     # By default for OVS we restrict every block device:     # filter = [ "r/.*/" ] and comment the line starting with "filter" as above. Now you have to discover the raw-lun presented and, next, activate volume-group and logical-volumes: #!/bin/bash for HOST in `ls /sys/class/scsi_host`;do echo '- - -' > /sys/class/scsi_host/$HOST/scan; done CPATH=`pwd` cd /dev for DEVICE in `ls sd[a-z] sd?[a-z]`;do echo '1' > /sys/block/$DEVICE/device/rescan; done cd $CPATH cd /dev/mapper for PARTITION in `ls *[a-z] *?[a-z]`;do partprobe /dev/mapper/$PARTITION; done cd $CPATH vgchange -a yAfter that you will see a new device:[root@ovs01 ~]# cd /dev/6000F4B00000000000210135bef64994[root@ovs01 6000F4B00000000000210135bef64994]# ls -l 6000F4B0000000000061013* lrwxrwxrwx 1 root root 77 Oct 29 10:50 6000F4B00000000000610135c3a0b8cb -> /dev/mapper/6000F4B00000000000210135bef64994-6000F4B00000000000610135c3a0b8cb By your OVM-Manager create a guest server with the same definition as on VI:same core number as VI source guestsame memory as VI source guestsame number of disks as VI source guest ( you can create OVS virtual disk with a small size of 1GB because the "clone" will, eventually, extend the size of your new virtual disks )Summarizing:source-virtual-disk path ( VI ):/dev/mapper/6000F4B00000000000210135bef64994-6000F4B00000000000610135c3a0b8cbdest-virtual-disk path ( OVS ):/OVS/Repositories/0004fb00000300006cfeb81c12f12f00/VirtualDisks/0004fb000012000055e0fc4c5c8a35ee.img ** ** = to identify your virtual disk you have verify its name under the "vm.cfg" file of your new guest.Clone VI virtual-disk to OVS virtual-diskdd if=/dev/mapper/6000F4B00000000000210135bef64994-6000F4B00000000000610135c3a0b8cb of=/OVS/Repositories/0004fb00000300006cfeb81c12f12f00/VirtualDisks/0004fb000012000055e0fc4c5c8a35ee.img Clean unsupported parameters and changes on OVS.1.

• Desktop interface crashes after software updates

  - by N.C. Weber

  Recently, after installing Ubuntu software updates on the evening of December 7th, 2012, my desktop interface crashes regularly leaving me with a command line screen with a long string of automated commands showing (I assume what goes on behind the pretty desktop). At first, I thought it was only crashing whenever I played DirectX games in WINE, but now it crashes if I open the native Firefox browser or if it's doing nothing at all but sitting there. Apport attempts to report the bugs after restart, but often they crash as well. I've done a SMART check on the hard drive, and everything report OK. No read errors, no bad sectors. I am using an Acer Extensa 4620Z Memory: 2.0 GiB Processor: Intel Pentium Dual CPU T2370 @ 1.73GHz x 2 GraphicsL: Intel 965GM x86/MMX/SSE2 OS: Ubuntu 12.10 32-bit Disk: 116.0 GB with 33.4 GB Available

  If you have recently installed SOA Suite, created a domain and then tried to start it only to find it fails with the error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. the solution is to edit the file <domain home>\bin\setSOADomainEnv.cmd/sh (depending on your platform) and modify the line: set DEFAULT_MEM_ARGS=-Xms512m -Xmx1024m to something like: set DEFAULT_MEM_ARGS=-Xms512m -Xmx768m Save the file and then try to start your domain again.

• Broken links in content reports when tracking subdomains with Google Analytics

  - by Rob Sobers

  I have a tracking code that I use on my main site and my blog, which is on a subdomain: www.example.com blog.example.com I have a single profile in Google Analytics. I use advanced segments to look at traffic to the main site vs. traffic to the blog. Problem 1: When I'm browsing my content reports under Standard Reporting, the "Page" column doesn't show the top-level or sub-domain, so I can't differentiate www.example.com/index.html from blog.example.com/index.html easily. According to the docs, this filter is supposed to make GA prepend the hostname to the page URL in your content reports, but it doesn't seem to work. Problem 2: When I click on the little "Open in new window" icon next to a given page in a content report line, it always assumes the page lives on www.example.com, so I get 404s when the page is actually on blog.example.com. Is there a good solution for these subdomain tracking problems?

• Setting TeX Live path for root

  I have installed TeX Live 2011 vanilla and I have trouble setting the TeX Live path for root (in Ubuntu 11.10). The problem is that when I run sudo tlmgr I get: sudo: tlmgr: command not found To fix the path for non-root it was sufficient to add PATH=/usr/local/texlive/2011/bin/x86_64-linux:$PATH to /etc/profile. I have tried adding this same line to /root/.bashrc and I have also tried to add it to /etc/profile.d/zzz-texlive.sh like Herbert suggest in http://tex.stackexchange.com/questions/26624/tlmgr-inaccessible/26626#26626 but it does not help.

• Shortcut to change Launcher 'Hide' setting

  - by joris

  When I'm working on my laptop I have periods that I am only using a couple of programs, so the default intellihide setting of the Launcher ('Dodge windows') is very handy. But I also have periods that I have to switch very often between programs, and then I find it very useful (and better for my workflow) that the Launcher doesn't hide. Now, every time I wan't to switch I have to open CCSM and change the setting (Unity plugin - Hide Launcher), but it would be easier if I could use a shortcut for it. So my question: Is there a way to create a shortcut to switch between (or change) the two settings of Compiz? I thought of command line interface to compiz, but I couldn't directly find something like that.

• Cleaning a dataset of song data - what sort of problem is this?

  - by Rob Lourens

  I have a set of data about songs. Each entry is a line of text which includes the artist name, song title, and some extra text. Some entries are only "extra text". My goal is to resolve as many of these as possible to songs on Spotify using their web API. My strategy so far has been to search for the entry via the API - if there are no results, apply a transformation such as "remove all text between ( )" and search again. I have a list of heuristics and I've had reasonable success with this but as the code gets more and more convoluted I keep thinking there must be a more generic and consistent way. I don't know where to look - any suggestions for what to try, topics to study, buzzwords to google?
