• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• Should I use parentheses in logical statements even where not necessary?

  - by Jeff Bridgman

  Let's say I have a boolean condition a AND b OR c AND d and I'm using a language where AND has a higher order of operation precedent than OR. I could write this line of code: If (a AND b) OR (c AND d) Then ... But really, that's equivalent to: If a AND b OR c AND d Then ... Are there any arguments in for or against including the extraneous parentheses? Does practical experience suggest that it is worth including them for readability? Or is it a sign that a developer needs to really sit down and become confident in the basics of their language?

• Getting a texture from a renderbuffer in OpenGL?

  - by Rushyo

  I've got a renderbuffer (DepthStencil) in an FBO and I need to get a texture from it. I can't have both a DepthComponent texture and a DepthStencil renderbuffer in the FBO, it seems, so I need some way to convert the renderbuffer to a DepthComponent texture after I'm done with it for use later down the pipeline. I've tried plenty of techniques to grab the depth component from the renderbuffer for weeks but I always come out with junk. All I want at the end is the same texture I'd get from an FBO if I wasn't using a renderbuffer. Can anyone post some comprehensive instructions or code that covers this seemingly simple operation? EDIT: Linky to an extract version of the code http://dl.dropbox.com/u/9279501/fbo.cs Screeny of the Depth of Field effect + FBO - without depth(!) http://i.stack.imgur.com/Hj9Oe.jpg Screeny without Depth of Field effect + FBO - depth working fine http://i.stack.imgur.com/boOm1.jpg

• Is it Considered Good SQL practice to use GUID to link multiple tables to same Id field?

  - by Mallow

  I want to link several tables to a many-to-many(m2m) table. One table would be called location and this table would always be on one side of the m2m table. But I will have a list of several tables for example: Cards Photographs Illustrations Vectors Would using GUID's between these tables to link it to a single column in another table be considered 'Good Practice'? Will Mysql let me to have it automatically cascade updates and delete? If so, would multiple cascades lead to an issues? UPDATE I've read that GUID (a hex number) Generally takes up more space in a database and slows queries down. However I could still generate 'unique' ids by just having the table initial's as part of the id so that the table card's id would be c0001, and then Illustrations be I001. Regardless of this change, the questions still stands.

• Auto save, filter applied screen shots

  - by DUKE

  Unlike Windows, it is very easy to take screen shots of selected area of the screen in Ubuntu. But I am researching how to have the following features when taking screen shots of the selected area: (1) The final output should be automatically saved to a location, for example on the desktop. (This feature is available in Mac OSX) (2) A filter (such as drop down shadow) should be automatically applied to the image. The above should happen as soon as the selection is done, without poping up any dialogs and expecting any inputs from the user.

• Why is Android VM-based? [closed]

  - by adib

  By about 2004, it was clear that ARM is the clear winner for mobile CPUs, beating out MIPS, SH3, and DragonBall. PocketPC (Windows Mobile) applications was natively-compiled (at least most of them - except for .NET compact and its competitors). Likewise, Apple's iOS (named iPhone OS at the time) prefers natively-compiled applications. Then why Android chose a virtual machine based system stack? (the Dalvik VM). Wouldn't it be simpler to just compile applications down to ARM code using GCJ or something? Is the decision influenced by the J2ME-way of doing things, or was just because it's "cool"? Perhaps like most things Java, the culture that prefers multiple levels of indirection and abstractions, they just added another layer of abstraction for "just in case"?

• Page not found in browsers

  - by Chetan

  I'm using ubuntu 12.04.1, last upgraded from 12.04 I'm using mts mblaze to access internet. Two days ago, I was using vpn on my system, suddenly cisco disconnected & my system hung while I was accessing my office system. I didnt' have any other idea, so I forcibly shut down the system. After that, connection is made, but firefox or chromium both don't find any page. I think there's some problem with the system package. Please let me know a good solution. Regards, Chetan

• How do you install less css command line compiler?

  - by chrisjlee

  From my understanding and correct me if I'm wrong, I have to get ruby or NPM installed to get the less css compiler working. I don't have any ruby installed and I'm not really sure how to get my computer to that point. I also want to minimize my footprint; installing the minimal amount of ruby libraries if possible (because i will never use ruby except for when i run less). What are the steps involved in getting less working and running? Before you down vote, I know there was this previous thread (Less CCS compiler install). This particular person already has some other packages installed. I'm trying to figure out all the packages needed to get to that point. Or if someone could point me to the right documentation I would be thrilled!

• 12.04 in Virtualbox is keep losing my wireless connection

  - by Derek

  I've Windows 7 as the Host OS, Ubuntu 12.04 as the guest and a Netgear WG111v2 as the USB Wireless device. Its connected to an open Wi-Fi network at work to bypass my works crazy strict filtering, When on the domain. I currently have network eth0 turned off in the virtualbox settings so the only network source would be through the USB device at wlan1. Its odd but the wireless seems extremely temperamental, I constantly have to ifconfig wlan down then ifconfig wlan1 up to get it back online. I know this might be super vague just curious if anyone has tried something like this or run into anything like it to point me in a direction I might not be seeing.

• How can I get my mysqld-swamped CPU under control?

  - by Shay Guy

  I was AFK for about 24 hours and came back to find gnome-system-monitor saying all four CPU cores on my laptop were running at full throttle. mysqld is taking up more than one full core; when I tried to end the process, it restarted with a new PID. Then there's ksoftirqd/0-3, which apparently has something to do with interrupts, but I can't tell from Google what I'm supposed to do with those four particular processes. They're taking up a quarter or more of my processor cycles. Then there's Chrome, but I can probably handle that on my own -- how do I cool down the other processes giving me problems?

• Is medium-resolution a good middle ground for web images?

  - by ColdSharper

  I'm used to thinking of hi-res 300 ppi and above, and lo-res, 72 or 96. But today I got an image that was 240 ppi, and da boss wanted as high res as possible. It was a huge file, but when I resized down to 700px wide in PS, optimized jpeg with no compression, without changing the res the result was a 129KB file that looks decent on most browsers (at least my box...who knows about old monitors, etc.) Did I miss a conference when I was on a break? Are others doing medium-res?

• Fail to load Ubuntu11.10 onto ASUS PC 1015PX

  - by strugglingbadly

  My new ASUS 1015PX has the usual windows on the SDA1 partition - 100Gb, followed by SDA2 - 15Gb - with the recovery for windows, SDA3 with 183Gb for drive 'D' for windows. ASUS uses SDA4 - 19Mb for it's own use. 11.10 on an USB will load Ubuntu on a try basis and it seems OK, but every time I attempt an install, Ubuntu quickly shuts down and the restart process begins. Repeat endlessly. I've tried 10.4 netbook but that will not boot at all with the machine reporting - unknown keyword in config file gfxboot vesamenu.c32: not a COM32R image. I've gone through the above about 6 times each with the same results. I have also tried the above with the partitioning unchanged, and using gparted, with SDA3 formatted to ext4, windows 'D' reduced to 8Gb providing a 175Gb unallocated space - all to no avail. Please help

• Non-unique display names?

  - by Davy8

  I know of at least big title game (Starcraft II) that doesn't require unique display names, so it would seem like it can work in at least some circumstance. Under what situations does allowing non-unique display names work well? When does it not work well? Does it come down to whether or not impersonation of someone else is a problem? The reasons I believe it works for Starcraft II is that there isn't any kind of in-game trading of virtual goods and other than "for kicks" there isn't much incentive to impersonate someone else in the game. There's also ladder rankings so even trying to impersonate a pro is easily detectable unless you're on a similar skill level. What are some other cases where it makes sense to specifically allow or disallow duplicate display names? (I have no idea what to tag this as. I went with game-design because I needed at least 1 tag and I don't have rep to create new ones yet.)

  I`ve installed Ubuntu 12.10 on 3 different machines: Acer AspireOne Netbook Lenovo T60 Notebook Desktop - P5P77 - Asus mainboard - I3 - porcessor I have the same issue on all of themm they won`t restart (Shut Down work), I can see the proceses are killed but it freezez on black screen total iresponsive. Even when I access the bios config to modify something then Save&Exit then restart I get the same thing. This is the same for all 3 machines. I also cleaned up the desktop system, last version of bios update, full HDD format, fresh win7 installed (practicly no trace of the old Ubuntu 12.10) still the same problem. Some time ago I had Ubuntu 11.10 on the desktop system, it worked perfectly. I also mention that I tried all combinations of ACPI settings in BIOS, unfortunately with no results. Please advice, I am a little desperate :)) Best regards, Cristian, Romania

• If I create a link to a folder, how can I get from that linked folder to the "real" folder from within Nautilus?

  - by snowguy

  Say I have a folder several layers down in my documents folder. And I want easy access to it from my desktop. To do that I: Go to the parent folder in Nautilus. Right click on the folder's Icon and choose Make Link Cut / Paste the new "Link to ..." folder onto my desktop. Great. And mostly this works fine for me. But suppose I want to get to that folder's parent. I can of course get there using the original path--what Nautilus calls the "link path" which I can see in the properties of the folder. But that seems harder than it ought to be. How can I click on the folder and go to the link path directly?

• How far back do you use your version control and for what reason?

  - by acidzombie24

  Typically when i work on a project i only go back a few days or the last major change when i decide to do something drastic. I sometimes notice i broke a test or a feature and overlooked it for a few weeks so i may go back a month or two and see if the feature or test is broken and trace down the week i broke it. Then find what change did it. On a long term project over the span of a year. Do you actually go back 6+ months and if so why?

• Beginner: How to Make Explorer Always Show the Full Path in Windows 8

  - by Taylor Gibb

  In older versions of Windows the Title Bar used to display your current location in the file system. In Windows 8 this is not the default behavior, however, you can enable it if you wish to. Display the Full Path in the Windows Explorer Title Bar Press the Windows + E keyboard combination to open Windows Explorer and then switch over to the View tab. On the right-hand side click on options and then select Change folder and search options from the drop-down. When the Folder Options dialog opens, switch over to the View options. Here you will need to tick the Display the full path in the title bar check box. That’s all there is to it.

• Working with logout dialog box - text error

  - by aaron.kyle

  I am having a problem with the shutdown dialog box for Ubuntu 12.04. If I am logged in as any user and press shutdown, I see the box with the question 'Are you sure..." and its usual options. Shutting down when I am not logged in as a specific user, however, displayed only square boxes. An image of this error can be found here: I believe this error started a few weeks ago when i accidentally changed the group for my root system directory, so it might be a permission thing or an improperly assigned group lingering somewhere. The trouble is that I don't know where the text for this box is stored, and no idea where to begin checking. Can any one point me in the right direction?

• A record point not working

  - by Peter

  I'm trying to do an A record point to transfer the hosting of a domain from one provider to another. I don't want to change the nameservers as this will result in emails going down. The output when I dig for the domain shows the correct IP (78.46.63.87) for the new host. I know A records can take a while to propagate but Its been over 36hrs now and I still keep getting this error(below) when I try to pull the domain through as an addon domain via Cpanel on the new host. Are the old nameservers conflicting with the A record point? here's the error: Using nameservers with the following IPs: 208.80.125.4,208.80.126.4,208.80.124.4,208.94.148.4 Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver.

• New Java ME security app, Rapid Tracker, is now full version

  - by hinkmond

  Rapid Protect has updated it's Java ME security app to be the full version now instead of a dumbed down version that ran on feature phones. Now, that's progress! See: Full Rapid Tracker on Java ME Here's a quote: Rapid Protect, a leading company focused on mobile based safety, security and collaboration space announces major feature enhancements to its award winning "Rapid Tracker" mobile applications. In addition to many new features, it announced availability of Full Rapid Tracker application on J2ME non-smart feature phones. Hmmm... "on J2ME non-smart feature phones". I wonder if by "non-smart" they mean another word... Perhaps, "non-iDrone-Anphoid"? Hinkmond

• Where to find PHP version usage stats?

  - by Darren Cook

  My original question was: what percentage of sites are using php 5.4.x? (As it has some very interesting new features.) With secondary questions like how many of the cheap web hosting places have upgraded, which versions of the linux distros include it, etc. But I'm coming up blanks. http://php.net/usage.php stops at July 2007, and the nexen.net website seems to have stopped in 2008. At SecuritySpace they only list the web servers, not php versions. The TIOBE link isn't what I'm after (it doesn't -- and couldn't -- break down by version number. I thought php.net might show download numbers, but I cannot see them anywhere. I kind of answered the distro question, but it requires a lot of clicking around at distrowatch.com. E.g. I see here that Ubuntu offers php 5.4.6 in the latest snapshot, but the latest release (Ubuntu 12.04) has 5.3.10.

• Ubuntu 12.04 does not power off

  - by G K

  I'm not able to power off Ubuntu, which was working fine a couple of days ago. When I click shut down, a blank screen appears and stays like that forever. It does not power off by itself and I'm forced to physically power off using the power button. I've even tried 'sudo shutdown now' and 'sudo shutdown -h now' and both don't seem to work! Please suggest some fix for this problem. Thanx in advance. Edit: Restart works fine. Also 'sudo poweroff' doesn't work!

• Are there any alternative JS ports of Box2D?

  - by Petteri Hietavirta

  I have been thinking about creating a top down 2D car game for HTML5. For my first game I wrote the physics and collisions my self but for this one I would like to use some ready made library. I found out Box2D and its JS port. http://box2d-js.sourceforge.net It seems to be quite old port, made in 2008. Is it lacking many features of current Box2D or does it have major issues with it? And are there any alternatives for it?
