• I cannot see the drives on my computer

  - by Joseph

  I'm a new Ubuntu user and I installed this Ubuntu 12.04 fromn a usb stick. It all went fine(I think) but as I notice, there are no drives shown on the menu. I tried some command in the terminal to see if the drives are available and yes, they are available. My problem is how to make these drives show up on the menu above. Sorry if this question is somewhat vague. (I removed the image because I am not allowed to add an image because I have insufficient reputation)

• I've had Tomboy twice delete a single important note. What's going on there?

  - by Mittenchops

  Not sure what's going on here, but here's the best I can describe: I use Tomboy extensively, for notes, collecting throw-away passwords,etc. Once a couple of months ago, a very important note just disappeared. No reference to the title, no deleting, no way of tracking it down---it was just like it had never existed. The same thing just happened today. I think the note in question was actually open when I rebooted, so maybe that's related. Has anyone else encountered something similar? EDIT: Happened 3 times Seems to be the last note I have open when shutting down (which is usually the most important) is deleted without a trace.

• HP 6735s Brightness hotkey problem; where is brightness panel?

  - by Paul

  I have installed ubuntu 11.10 on my laptop hp 6735s. The screen is often too dark and i want to make it brighter, although the hotkeys Fn+F7/F8 are not working. I have tried some things: Firstly it appears that sometimes they are in fact working, after reboot they either work and continue to do so or they don't. I've read about a brightness applet; but where can i find or install it? I have tried some grub options; acpi_osi=Linux and acpi_backlight=vendor but nothing changes. I don't want to add another question but since it might be related: my laptop also gets quite hot, i'm having doubts whether ubuntu connects to the available sensors and cooling plans (or how does it work???); sensors (or psensor) only shows 2 sensors both named temp1. Any help is greatly appreciated! Paul

• Where can I locate business data to use in my application?

  - by Aaron McIver

  This question talks about any and all free public raw data which appeared to have valuable pieces but nothing that really provides what I am looking for. Instead of using a socially defined listing of businesses (foursquare), I would like a business listing data set of registered businesses and associated addresses that could then be searchable based on location (coordinates). The critical need is that the data set should be filterable based on varying criteria (give me all restaurants, coffee shops, etc...). If the data is free that is great but anywhere that sells this type of data would also suffice. Infochimps looked like a possibility but perhaps something a bit more extensive exists. Where can I find a free or for fee data set of registered business that is filterable based on type of business and location?

• Get phone number of (via mobile networks) browsing mobile device

  - by TrialUser

  I recently figured out, that the web site of my phone provider (mobile) mysteriously identifies me and automatically logs me into my account when I'm accessing with my android phone, as if it knew my phone number. (I used several browsers. When I'm using the phone as WLAN hotspot and access the same site from another device that doesn't happen.) How does my phone provider do that? On the one hand, as a programmer, I'd like to be able to do that too, but on the other hand, as a user, I'm kind of scared. What information do they have, such that they (believe they) are able to identify me just by my device? I hope this question isn't completely inappropriate for this site; feel free to add better tags — it's hard to find the right ones without knowing the Webmasters site at all.

• SEO: Is there a limit to how long titles/descriptions should be?

  - by jiewmeng

  I am trying to fill up title and meta description for my Tumblr blog. The way I will do that is via the themes. For the title, it isn't too much of an issue, I can just get the title for the post although some post types do not have titles. The main question is about the description. I am thinking of using the start of the body content. For now, there is no way to limit the length of body content. I wonder if its OK to have the whole body in the description? I have contacted Tumblr support to suggest that they have a way of creating limiting text length in their template tags.

• Useful versioning scheme for a git project?

  - by Oliver Weiler

  I have a small github project, which I need to add an option to to output some version number on the commandline. The problem is I have no idea how to "compute" the version number. Is this some random process? Should I just start at 1.0 (probably creating a tag or something), and put a number after . for fixes? I know this question is a bit vague... I just had never to deal with this, and want to use some sane versioning scheme. EDIT Im also interested into how to update this version number automatically, maybe using something like a git hook.

• Mount encrypted volumes from command line?

  - by cha

  If I have an encrypted external disk (or an internal disk that is not in fstab), I see an entry for it in Nautilus -- with an entry like "X GB Encrypted Volume". I can click on this volume, and am prompted for a password to decrypt and mount the device. But how do I do this from the command line? This wiki page, and other docs I can find, only refer to GUI methods of decrypting the device; but this won't do in the context of headless servers or SSH logins. Is there a simple way to get devices to mount to automatic locations in "/media" just like they would with the GUI? (I'm not asking about encrypted home directories -- I'm aware of ecryptfs-mount-private. This question is about additional encrypted volumes.)

• How can you predict the time it will take for two processes in two different machines in a cluster to communicate?

  - by Dokkat

  I am trying to develop a computing application which needs a lot of memory (500gb). Buying a single machine for that is overly expensive. I can, though, buy ~100 small instances on Digital Ocean or similar, divide the memory in blocks and use TCP to emulate shared memory between the instances. Now, my question is: how can I measure/predict the time it will take for two processes in two different machines like that to share information, in comparison to IPC and shared memory? Are there rules of thumb? I don't want exact values, but knowing more or less how much faster one is would be very helpful in visualising the feasibility of this approach.

• trying live-usb 12.04.1 image on an old desktop

  - by 213441265152351

  I am trying to load Ubuntu 12.04.1 32-bit desktop image on an old desktop computer. The system shows the initial menu, but after a while, I get an error like the one in the following two screenshots (it takes a few seconds to go from one to the other in the screen): I tried to load it using the different USB ports at the back of the computer, just in case, and I get basically the same error. Find another screenshot from another try: Any ideas what might be happening? NOTES: I checked the md5sum of the iso file to be e235b63c02644e219b7bf3668f479c9e *ubuntu-12.04.1-desktop-i386.iso. I did the 'Test' on the laptop where I created the USB drive, and it loads up correctly. The desktop computer in question is an old AMD Duron 1800MHz with 512MB RAM. I ran a memtest on the computer, and all went fine.

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• Aptana Studio 3 does not start up in Ubuntu 12.10

  - by Agent47DarkSoul

  I followed the instructions provided here to install Aptana Studio 3 in my Ubuntu 12.10. I have completed all the steps with out any problems. When I click the Aptana icon in my Unity bar nothing happens. No error pops up! I gave permission on the sh file and on the directory (/opt/Aptana_Studio_3) but still same problem. If I try executing the sh file in the /opt/Aptana_Studio_3 folder, it says "Syntax error: "(" unexpected Aptana". Also I cannot execute the Aptana binary file directly. I have been trying to solve the problem for a while now. Any help would be much appreciated. EDIT: I have Oracle Java 7 installed. I have read some post about backwards compatibility problem with Java 6 but dont know whether that's the issue. I will edit the question if I find something new.

Then the simple question , is there any resources of how did they programm this games? Or any idea of the simple ideas repeated each game to game in the old style retro games.

• Preventing Duplicates on Google

  - by abel

  I am currently using a rewrite rule to enable access to .php pages, without using the php extension. However to prevent old links from breaking, the pages can still be accessed via links containing the .php extension too. For eg. domain.com/page.php can now be accessed at domain.com/page All the links on the website now use domain.com/page type links within the site. However older incoming links will still link to the .php pages, meaning Google will index both pages and mark them as duplicate. I have two plans to remedy the situation. Use a php 301 redirect: When a page is accessed with the .php extension, I can redirect each page individually using a 301 redirect using php Using Canonical: Place a canonical tag on each page, pointing to the ".php" less version My Question: Are both methods equally efficacious in preventing Google from indexing my ".php" pages? Which method should be preferred, by convention or otherwise?

• portfolio building, working for closed-source vs open-source?

  - by jondavidjohn

  I've currently graduated from my first run at higher education, landed my first full-time gig as a web application developer, and absolutely love it. My question is that in looking for jobs I ran across many jobs that require a certain level of experience and code examples. Much of the work I am doing is both protected by a login, and closed source. How does someone, that is just starting out and needs to be building a resume, go about preparing for the next job. (no matter how much i love my current job, i feel like it's only responsible to always be preparing)

• Can't set 1280x1024 with Nvidia Geforce 8400 GS

  - by torbengb

  I've just installed 10.04 LTS using the Windows installer. The system hangs during boot; the splash screen is frozen and it accepts neither Ctrl+Alt+F2 nor Ctrl+Alt+Del, only a hard reset. (I'm a linux noob.) When I edit the default Grub boot option to omit quiet splash, it gets to the point saying * setting sensors limit [OK] _ and there it stays. I can only get to the desktop using the Grub recovery boot option, of course with a lower resolution (800x600) but everything else seems to work fine. As I said, this is a new install. The only thing I've done is to use the Update Manager to get everything up to date, and activate the newest Nvidia driver using the "Hardware drivers" window. I had a similar problem when I installed 9.04 a year ago, and at that time posted this question with an answer that worked - this doesn't work with 10.04. Running nvidia-xconfig to create a new xorg.conf didn't fix it either (while in Recovery boot).

• DLNA Server/Control Point like Windows Media Player

  - by csde_rats

  Yes, I know that most questions ending with "like Windows" are odd, but this one really bothers me ;) If you ever used some DLNA renderer (in my case DLNA-enabled loudspeakers) you probably know the handy "play to"-feature. From my knowledge of DLNA stuff I would guess, that Windows Media Player is both a DLNA server and control point here, so my question is: Is there any similar software for Linux accomplishing the same thing with minimal configuration effort? I normally use Banshee for my music library, but it doesn't seem that there is anything available for Banshee...

• 301 Redirects for regional variants of a homepage

  - by Adam Jenkin

  I am planning on implementing a website which has regional homepage variants. For Example: mycompany.com/europe mycompany.com/us The rest of the site is region agnostic and content will continue such as: mycompany.com/news mycompany.com/about-us etc For homepage (.com) requests, I plan on redirecting users to the correct homepage variant (via 301). If I cannot determine the correct one, I will fallback to redirecting them to the US homepage (/us). From an SEO point of view, firstly is this ok? or should I be doing anything additional to this for making search engines aware of the regional differences? As crawlers are region agnostic, I plan on directing them to the US page with a 301, or should I have something on the .com page which they use? Being that the regional homepage's will likely be the most visited pages, they should show up in result sitelinks when searching for mycompany (which I think is a good thing). Apologies for the slightly open question - I know anything SEO related is more opinion/best practice than fact but am purely looking for advice.

• Will having a website duplicated on multiple top level domains be penalised by search engines [duplicate]

  - by user1020317

  This question already has an answer here: Will having multiple domains improve my seo? 7 answers I'm running a website for a global company, and although we rank first in search engine results here in Ireland, a search done from other countries doesn't rank us as highly. If I register the domain at other top level domain names (eg. example.co.uk, example.nor etc.) and then just mirror the .com site to those other domains, will I be penalised by search engines for having duplicate content? Has anyone else faced a similar problem and found a way to capture the global search engine? Thanks.

• Best keyboard to use with RollerMouse

  - by jrdioko

  I recently purchased a RollerMouse, which seems like an excellent way to eliminate pain caused by mousing. My question is: what good keyboard can other programmers recommend that would work well with it. I currently have a Microsoft ergonomic keyboard, but the curve and large wrist rest make it hard to use with the RollerMouse. By "good", I mean: Works with the RollerMouse (no wrist rest) Ergonomic (a slight curve or other features designed to be easy on your wrists/arms) Good for programming (that would be its primary use, no need for fancy media buttons or anything like that) Suggestions?

• Apps capable of mounting/unmounting CD/DVD Images with multi-sector or protected format

  - by Luis Alvarado

  What apps for Ubuntu exist that can mount/unmount CD/DVD images. Image formats like cue, bin, iso, nero format, etc... Needed features: Emulate protected CD/DVD like Daemon-Tools Mount multi-sector images Converting other formats (including multi-sector images) to ISO format. UPDATE - Updated question to "need the 3 features above instead of having them as optional". This 3 features are needed to be able to use images that have any of this features enable. For normal mounting/burning image apps you can see here: How can I graphically mount ISOs? Can I mount an ISO without administrative privileges? How burn or mount an ISO file?
