• Permanently disabling touchpad in ubuntu 12.04

  - by Andreas

  I'm looking for a way to permanently disable the touchpad in ububtu 12.04 (my computer is a Lenovo Thinkpad Edge on which it isn't possible to disable it in the bios). I tried the applications GPointingDeviceSettings and synaptiks 0.8.1 as well as the applets touchpad-indicator and Jupiter. None of these does the trick of disabling the touchpad permanently. Jupiter comes closest - it remembers that I have disabled the touchpad after restart - but when I login after the computer has been in suspend mode, the touchpad is enabled again. Can anyone help me in disabling the touchpad possibly at a lower level so it won't in any way be enabled unless I choose to enable it? I'm totally new to linux so a detailed explanation would be much appreciated ... The links, so far, doesn't address my question. I have no problem turning the touchpad off and making it stay off after reboot but when I login after the computer has been in an altered power mode it's on again. Isn't there a way to permanently disable a device like touchpad?

• Where can I find an exhaustive list of meta tags and what they do?

  - by leeand00

  It seems to me that there are a ton of <meta> tags for all sorts of different purposes out there... Though they all follow a similar format of <meta name="" content="" /> they seem to serve a vast variety of different purposes from controlling the crawling of search engine bots, providing search engine bots with descriptions of pages, to making sure a page display correctly on a mobile device. These tags fall into so many different categories I was wondering if anyone had a wiki or master list of possible meta tags and their content.

• SQL, moving million records from a database to other database [migrated]

  - by Ryoma

  I am a C# developer, I am not really good with SQL. I have a simple questions here. I need to move more than 50 millions records from a database to other database. I tried to use the import function in ms SQL, however it got stuck because the log was full (I got an error message The transaction log for database 'mydatabase' is full due to 'LOG_BACKUP'). The database recovery model was set to simple. My friend said that importing millions records using task-import data will cause the log to be massive and told me to use loop instead to transfer the data, does anyone know how and why? thanks in advance

• How To Use Google Authenticator and Other Two-Factor Authentication Apps Without a Smartphone

  - by Chris Hoffman

  Google, Dropbox, LastPass, Battle.net, Guild Wars 2 – all these services and more offer two-factor authentication apps that work on smartphones. If you don’t have a supported device, you can run an alternative application on your computer. When you log in, you’ll need to enter a time-based code from the app. Two-factor authentication prevents people who know your password – but don’t have the app and its security key – from logging in.

• How do I detect multiple sprite collisions when there are >10 sprites?

  - by yao jiang

  I making a small program to animate the astar algorithm. If you look at the image, there are lots of yellow cars moving around. Those can collide at any moment, could be just one or all of them could just stupidly crash into each other. How do I detect all of those collisions? How do I find out which specific car has crash into which other car? I understand that pygame has collision function, but it only detects one collision at a time and I'd have to specify which sprites. Right now I am just trying to iterate through each sprite to see if there is collision: for car1 in carlist: for car2 in carlist: collide(car1, car2); This can't be the proper way to do it, if the car list goes to a huge number, a double loop will be too slow.

• Enable wifi on my computer - firmware missing

  - by Sarah

  I am attempting to set up a wireless network on 11.04, freshly download today. The router is on and working. However, I do not have a wifi "card" (which I am assuming is a little USB-type thing that allows internet access, but correct me if I am wrong) and every time I try to type in the MAC address and everything, nothing works. I also get the "firmware missing" error when I scroll over the signal strength, which I have tried looking up but have been unsuccessful with completely understanding it. I guess my main question is do I need another little device to be able to use wifi on my ubuntu? I do have an ethernet cable but another person is using it and I do not want to be tied down to that cable. the problem is that none of the wireless networks show up, however they show up when I go into Windows mode on my laptop. I get an error message at the top saying "firmware missing" which I have tried looking up but still have no straight answer for.

• Byte Size Tips: How to Stop OS X from Changing the Display Brightness Automatically

  - by The Geek

  After getting a new MacBook Air and deciding to try out OS X for a while, I started wondering why the battery would suddenly start dying really fast, but only when I was sitting at the kitchen table. That’s when I noticed the display brightness kept changing on its own… and realized the problem. OS X, just like your phone, and any modern device, tries to figure out the brightness of the room you’re in, and adjust the brightness of the screen. If you are over in Windows, it’s called “Adaptive” brightness, while your phone will just call it “Auto”. While this technology is great in theory, I don’t really need max brightness all the time, and I like to control it manually to make sure I’m getting the best battery life. Open up System Preferences, head to Displays. Then uncheck the Automatically adjust brightness setting.

• iPad Jailbreak &ndash; On The Lam In A Single Day

  - by David Totzke

  Exploits to jailbreak the iPhone are well known.  The iPad runs on the iPhone 3.2 firmware.  What this means is that the iPad was shipped with known security vulnerabilities that would allow someone to gain root access to the device. Nice. It’s not like these are security vulnerabilities that are known but have no exploits.  The exploits are numerous and freely available. Of course, if you fit the demographic, you probably have nothing to worry about. Magical and Revolutionary?  Hardly. Dave Just because I can…

• Resources for improving your comprehension of recursion?

  - by Andrew M

  I know what recursion is (when a patten reoccurs within itself, typically a function that calls itself on one of its lines, after a breakout conditional... right?), and I can understand recursive functions if I study them closely. My problem is, when I see new examples, I'm always initially confused. If I see a loop, or a mapping, zipping, nesting, polymorphic calling, and so on, I know what's going just by looking at it. When I see recursive code, my thought process is usually 'wtf is this?' followed by 'oh it's recursive' followed by 'I guess it must work, if they say it does.' So do you have any tips/plans/resources for building up your skills in this area? Recursion is kind of a wierd concept so I'm thinking the way to tackle it may be equally wierd and inobvious.

• Bad FPS for smaller size (OpenGL ES with SDL)

  - by ber4444

  If you saw my other question, well, there is still a little problem: Click here to watch on youtube Basically, the frame rate is very bad on the actual device, where for some reason the animation is scaled (it looks like the left side on the video). It is quite fast on the simulator where it is not scaled (right side). For a test, I submitted this new changeset that hard-codes the smaller size (plus increases the point size for HII regions to make the dust clouds more visible), and as you see in the video, now it is slow even in the simulator (left side shows the small size, right side shows the original size -- otherwise the code is the same). I'm clueless why it's soooo slow with a smaller galaxy, in fact it should be FASTER. As for general speed optimization (which is not strictly part of my question but is closely related to it, esp. if we need a workaround to speed things up), some initial ideas: reducing the number of items drawn may affect the appearance negatively but screen resolution could be reduced there are too many glBegin(GL_POINTS)/glEnd() blocks, we could draw more than just a single star at once

• Cant get lm-sensors to load ATI Radeon temp and fan or output all settings

  - by woody

  New to Linux and having minor issues :/ . I followed this guide initially but did not recieve the proper output and did not show my ATI Radeon HD 5000 temp or fan speed. Then used this guide, same problems exhibited. No issues installing and no errors. I think its not reading i2c for some reason. The proprietary driver is installed and functioning correctly according fglrxinfo. I can use aticonfig commands and view both temp and fan. Any ideas on how to get the ATI Radeon sensors working under 'sensors'? When i run 'sudo sensors-detect' this is my ouput # sensors-detect revision 5984 (2011-07-10 21:22:53 +0200) # System: LENOVO IdeaPad Y560 (laptop) # Board: Lenovo KL3 This program will help you determine which kernel modules you need to load to use lm_sensors most effectively.

• Platform Builder: Disable the USB Driver Dialog

  - by Bruce Eitman

  For a long time, Windows CE developers and users have wanted to disable the USB Driver Dialog that is displayed when an unknown USB device is plugged into the host controller.   Of course the question is always why would you want to do such a thing? The simple answer is that there are USB devices that are needed, like printers, which expose multiple functions to the bus, like scanners and faxes, which no Windows CE driver exists to support.   So the printer quietly loads a driver, but then the other functions cause a dialog to be shown. One solution is to create a USB Class driver that loads by default if no other driver has been loaded. This driver just accepts anything that it sees and then does nothing with it. Starting with the Windows Embedded CE 6.0 R3 March QFE/update, the USB 2.0 driver has a registry value to disable the dialog: [HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients]       "DoNotPromptUser"=dword:0   Setting the DoNotPromptUser value to 1 disables the dialog. The default value is zero, so the driver continues to behave in the same way it always did unless you change this registry value.     Copyright © 2010 – Bruce Eitman All Rights Reserved

• PyGame QIX clone, filling areas

  - by astropanic

  I'm playing around with PyGame. Now I'm trying to implement a QIX clone. I have my game loop, and I can move the player (cursor) on the screen. In QIX, the movment of the player leaves a trace (tail) on the screen, creating a polyline. If the polyline with the screen boundaries creates a polygon, the area is filled. How I can accomplish this behaviour ? How store the tail in memory ? How to detect when it build a closed shape that should be filled ? I don't need an exact working solution, some pointers, algo names would be cool.

• A good interpreted language for a small embedded project

  - by Earlz

  I have an mbed which has a small ARM Cortex M3 on it. Basically, my effective resources for the project are ~25Kb of RAM and ~400Kb of Flash. For I/O I'll have a PS/2 keyboard, a VGA framebuffer(with character output), and an SD card for saving/loading programs(up to a couple of Mb maybe) The reason I ask this here is because I'm trying to figure out what programming language to implement on the thing. I'm looking for an interpreted language that's easy for me to implement, and won't break the bank on my resources. I also intend for this to be at least possible to write on th device itself, though the editor can be interpreted(yay bootstrapping) Anyway, I've looked at a few simple languages. Some nice candidates: Forth BASIC Scheme? Has anyone done something like this or know of any languages that can fit this bill or have comments about my three candidates so far?

• .htaccess rewrite www to non-www and remove .html

  I need rewrite rules to redirect the following: http://www. to http:// /file.html to /file I've tried using a combination of these but each time it results in a redirect loop on one of the situations RewriteBase / RewriteRule ^(.*)\.html$ $1 [NC] RewriteCond %{HTTP_HOST} ^www.domain.co.uk [NC, L] RewriteRule ^(.*)$ http://domain.co.uk/$1 [R=301] I figure it's probably something to do with the flags but I don't know how to fix it.

• Smooth animation in Cocos2d for iOS

  - by MrDatabase

  I move a simple CCSprite around the screen of an iOS device using this code: [self schedule:@selector(update:) interval:0.0167]; - (void) update:(ccTime) delta { CGPoint currPos = self.position; currPos.x += xVelocity; currPos.y += yVelocity; self.position = currPos; } This works however the animation is not smooth. How can I improve the smoothness of my animation? My scene is exceedingly simple (just has one full-screen CCSprite with a background image and a relatively small CCSprite that moves slowly). I've logged the ccTime delta and it's not consistent (it's almost always greater than my specified interval of 0.0167... sometimes up to a factor of 4x). I've considered tailoring the motion in the update method to the delta time (larger delta = larger movement etc). However given the simplicity of my scene it's seems there's a better way (and something basic that I'm probably missing).

• How to make a Stop Motion or Time-lapse video with webcam?

  - by Seppo Erviälä

  I have a webcam that works as a v4l2 device. What is the most convenient way to capture either a stop-motion or time-lapse video? N.B. stop-motion and time-lapse are related but conceptually different. Time-lapse is where you take a photo of a scene at a set interval and then combine it into a video (that looks like it's going really fast). Stop-motion is where you control the scene and take an image for every change you make, to form an animation (eg Wallace and Grommit). An application for time-lapse needs to be able to take a photo at a set interval.
