• How can I solve display glitches and poor performance with ATI fglrx driver on my ThinkPad X100e?

  - by rewbs

  Hi all, I noticed that video performance on my Thinkpad X100e was very poor compared to Windows 7, so I installed the ATI fglrx proprietary drivers by using the "Additional Drivers" dialogue box. The system has an ATI Radeon Mobility HD 3200 chip. The result of installing the drivers is pretty devastatingly negative, with symptoms such as skewed content in windows, browser tabs and text boxes failing to refresh when their content changes. In fact, please excuse typos in this post, because I can't really see what I am typing. :) I also notice that HD video playback performance is no better - perhaps even worse - than prior to installing the drivers. Example of what I see: Here's the output of fglrxinfo: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 3200 Graphics OpenGL version string: 3.3.10237 Compatibility Profile Context Output of lspci | grep -i vga: 01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics] I'm on Ubuntu 10.10 with kernel 2.6.35-22-generic-pae. What can I try? Many thanks, -R

• Relaunch of wwwCoder.com

  It's been years since I've been active in the community, but I'm back with a newly redesigned wwwCoder.com. The site was taken over by spammers, and was essientially a ghost town, but I reworked it to bring a technology topics aggregator. The site provides full text searching on the popular podcasts, vidcasts, and blogs. Hit the home page to get a quick summary of what's going on with Microsoft developers. Let me know what you think.

• App for finding icons easily?

  - by artfulrobot

  Occasionally I need to use a custom icon for something - a launcher created with alacarte, a custom .desktop file, or just a particular folder viewed in Nautilus. I know there are LOADS of cool icons installed on my system at /usr/share/icons but browsing them is really awkward. Everything is scattered around, duplicated in different sizes (or symlinked to .svg) etc. So, say I'm looking for a text file icon, or a purple folder or such, searching is a faff, and then when you do find results you need to work out what the best quality one is. Made me think that someone might have written an app for this?

• Wordpress does not create directories?

  - by Marcappuccino

  First I will just tell you how my wordpress hierarchy looks like: /var/www has all of the wordpress files, which is different from how it is normally set up as /var/www/wordpress (symlinked to /usr/share/wordpress). So var/www contains all of the files that /usr/share/wordpress would have, and /usr/share/wordpress is symlinked to /var/www, with an extra /var/www/wordpress symlinked to /var/www to prevent possible compatibility issues. When uploading a file like a favicon or a .zip-ped theme, everything works fine, and when checking if the theme/favicon is uploaded, wordpress shows that it is, and points to a directory that it thinks that it had created, like http:/localhost/wp-content/uploads/2012/..., which it had not, because the uploads folder is empty! And so there is a broken link on the internet and the theme is displayed but it has just plain text (because it had reverted to a plain theme I think) Please help! I am sorry for such a long post but this is really quite a troublesome problem. I have chowned /var/www and /usr/share/wordpress to www-data.

• Powershell progress dialogs

  - by Norgean

  Creating nested progress dialogs in Powershell is easy. Let the code speak for itself: for ($i = 1; $i -le 2; $i++) {     Write-Progress -ID 1 -Activity "Outer loop" -Status "Tick $i" -percentComplete ($i / 2*100)     for ($j = 1; $j -le 3; $j++)     {         Write-Progress -ID 2 -Activity "Mid loop" -Status "Tick $j" -percentComplete ($j / 3*100)         for ($k = 1; $k -le 3; $k++)         {             Write-Progress -ID 3 -Activity "Inner loop" -Status "Tick $k" -percentComplete ($k / 3*100)             Sleep(1)         }     } } I.e. some text that explains what we're doing (Activity and Status), and ID numbers. Easy.

• Good interview programming projects

  - by bigtang

  I'm looking for some small programming projects that I can give potential employees to gauge their programming abilities. These will be programmers straight out of college. I'm looking for projects that would take someone a couple of hours and they would email back their answers post-interview. One example would be to take this paragraph of text and return a list of alphabetized unique words. After each word tell me how many times the word appeared and in what sentance(s) the word appreared in. Anyone have any good suggestions?

• How selective do we need to be for an index to be used?

  - by TiborKaraszi

  You know the answer already: It depends. But I often see some percentage value quoted and the point of this post is to show that there is no such percentage value. To get the most out of this blog post, you should understand the basic structure for an index, i.e. how the b+ tree look like. You should also understand the difference between a clustered and a non-clustered index. In essence, you should be able to visualize these structures and searches through them as you read the text. If you find...(read more)

• Importing synaptics settings

  - by Marcus

  I've got a Samsung Series 5 Chromebook which I've installed Ubuntu on. In Chrome OS the clickpad is working great but in ubuntu it hasn't got the same settings so I'm having problems with selcting text. I managed to find the setting in Chrome OS, it's 120 about lines of settings looking like this: Device 'SynPS/2 Synaptics TouchPad': Device Enabled (131): 1 Coordinate Transformation Matrix (133): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 Device Accel Profile (265): -1 Device Accel Constant Deceleration (266): 1.000000 Device Accel Adaptive Deceleration (267): 1.000000 Device Accel Velocity Scaling (268): 10.000000 Device Node (250): "/dev/input/event6" Now I would like to import these settings to Ubuntu. Is that possible?

• screen flickering

  - by lilicus

  When using some applications (LibreOffice, Chrome) it happens that screen flicker (just for a second, or even less than a second) or screen turns into black and then back to normal again... it all happens very fast (usually when clicking with the mouse)... for example, I was searching something in google chrome and list of possible results appeared - when I double click on the search text area (not list of possible results) screen flicker... or when changing border lines in LibreOffice Calc... I managed to create screen shot while using LibreOffice Calc. I am using Nvidia 313 drivers-updates on Ubuntu 13.04. What could be the problem?

• Two divs, one fixed width, the other, the rest

  - by Shamil

  I've got two div containers. Whilst one needs to be a specific width, I need to adjust it, so that, the other div takes up the rest of the space. Is there any way I can do this? <div class="left"></div> <div class="right"></div> // needs to be 250px .left { float: left; width: 83%; display: table-cell; vertical-align: middle; min-height: 50px; margin-right: 10px; overflow: auto } .right { float: right; width: 16%; text-align: right; display: table-cell; vertical-align: middle; min-height: 50px; height: 100%; overflow: auto } Thanks

• Ugly LibreOffice font

  - by tuhyk

  I have been experiencing this super annoying bug with fonts in LibreOffice. Please see below screenshot. The spaces between letters are just messed, no matter what font or level of zoom I choose. When I change the zoom level, the spacing is actually changing but still looks very ugly. I have a pretty much default instalation of Ubuntu. I installed a couple of fonts (droid, mscorefonts). I did not change any font settings. Fonts in other applications looks great. When I open the very same text in Google Docs or MS Web Word, it looks perfect. I would appreciate any help concerning this issue. Thanks!

• HP 655 notebook (ubuntu 12.04) keeps consuming energy after closing the lid

  - by Bastian van Binsbergen

  I am unable to change power settings so that when I close the lid the battery stops consuming energy. There are three options in the power settings menu: When the screen is closed: 1 Do nothing 2 Pause 3 Sleep First I could not change anything. I see all the options but I could not click on option 2 and 3. (grey text instead of black) I already made it possible to put in to sleep mode. But I can't pause (suspend) the laptop. Anyone an idea?

• After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

  - by Ryan P.

  Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

• Schema.org for Product Reviews

  - by Lynda

  I have a product reviews on a site and I am adding schema.org markup to the reviews. Here is the code I am using: <div class="blockquote-wrap"> <blockquote itemprop="review" itemscope itemtype="http://schema.org/Review"><span itemprop="reviewBody">Text of the review itself.</span> <cite><span itemprop="author">Author Name</span>, Location of Author</cite> </blockquote> </div> This is all the reviews are. When I test the page using Google's Structured Data Testing Tool I receive this error: Error: Incomplete microdata with schema.org. My question is what data is missing that is required? I don't see which data is required on the Schema.org page for reviews.

• Having trouble's understanding NIF model file format?

  - by NoobScratcher

  I'm attempting too develop a 3rd party application to make it easy to import 3d model part's into my mod for skyrim the plan was to have a fileviewer and preview window of the nif model but since , I don't know what the NIF file format actually is or where to get the vertex data from it or the hole nine yards of parsing a text file in detail I'm at a lost what to do. I'm very good at C++ but not at this super over complicated file formats , id much prefer .obj over the nif file format specification here -- http://niftools.sourceforge.net/doc/nif/index.html If someone could help me in understanding the file format in a natural and simple way and the exact parsing needed to create the 3D Model in the frustum and a explanation on how you figured that out would be happy to know. I use cygwin , notepad++ , win32 7

• Editing a command-line argument to create a new variable

  - by user1883614

  I have a bash script called test.sh that uses command-line argument: lynx -dump $1 > $name".txt" But I need name to be created from the argument by specific keywords in the argument. An example is: http://www.pcmag.com/article2/0,2817,2412941,00.asp http://www.pcmag.com/article2/0,2817,2412919,00.asp Both are two separate articles but are the difference can only be seen in those 12 characters. How do I create a variable from a url for those 12 characters? So that when I run test.sh in Terminal: ./test.sh http://www.pcmag.com/article2/0,2817,2412941,00.asp there is a text file saved as 0,2817,2412941,00?

• Deleted files not increasing available free space on Ubuntu (as reported by df -h)

  - by Homunculus Reticulli

  I am writing data munging scripts (python and bash), to munge data and import large quantities of text files into a database. I am currently in the test phase, so I am generating several K's of files and deleting them (the files consume about 20G of space). After a test run, I delete the files (sometimes without having imported into the database). I notice that there is a steady decrease in the amount of free space on my disk (as reported by df -h). I don't understand this, as I use rm * (in the data directory), and in the cases where I use Nautilus, I empty the Trash bin as well. Similarly, I notice that when I import the data into the (postgresql) database, and then delete the data from the tables using DELETE FROM tablename;, the size consumed in the postgresql data directory does not go down either. Currently, I have lost approximately 200G from hard drive, and I need to reclaim that - but don't know what to do to reclaim it - any ideas?. I am running Ubuntu 10.0.4 LTS + postgresql 8.4

• Where would you start if you were trying to solve this PDF classification problem?

  - by burtonic

  We are crawling and downloading lots of companies' PDFs and trying to pick out the ones that are Annual Reports. Such reports can be downloaded from most companies' investor-relations pages. The PDFs are scanned and the database is populated with, among other things, the: Title Contents (full text) Page count Word count Orientation First line Using this data we are checking for the obvious phrases such as: Annual report Financial statement Quarterly report Interim report Then recording the frequency of these phrases and others. So far we have around 350,000 PDFs to scan and a training set of 4,000 documents that have been manually classified as either a report or not. We are experimenting with a number of different approaches including Bayesian classifiers and weighting the different factors available. We are building the classifier in Ruby. My question is: if you were thinking about this problem, where would you start?

• Processing a stream. Must layers be violated?

  - by Lord Tydus

  Theoretical situation: One trillion foobars are stored in a text file (no fancy databases). Each foobar must have some business logic executed on it. A set of 1 trillion will not fit in memory so the data layer cannot return a big set to the business layer. Instead they are to be streamed in 1 foobar at a time, and have business logic execute on 1 foobar at a time. The stream must be closed when finished. In order for the stream to be closed the business layer must close the stream (a data operation detail), thus violating the separation of concerns. Is it possible to incrementally process data without violating layers?

• GPG and libpcap help

  - by Johnq

  I was trying to install the newest version of libpcap (as the version in the repositories doesn't seem current) and ran into the following problem. I copied the tcpdump-workers.asc text from the tcpdump website (which hosts libpcap as well) and imported the key to my keyring using gpg --import tcpdump-workers.asc. That when all well and fine but when I tried to verify the libpcap-1.4.0.tar.gz file against the key with gpg --verify, I ended up getting the message that unexpected data. was found. I am wondering if anyone else has run into this problem as the ancient technique of googling my problem has done little to answer my question.

• PHP efficiency question [closed]

  - by Ron

  Hello everyone. I am working on website and I am trying to make it fast as much as possible - especially the small things that can make my site a little bit quicker. So, my to my question - I got loop that run 5 times and in each time it echo something, If I'll make variable and the loop will add the text I want to echo into the variable and just in the end I'll echo the variable - will it be faster? loop 1 (with the echo inside the loop) for ($i = 0;$i < 5;$i++) { echo "test"; } loop 2 (with the echo outside [when the loop finish]) $echostr = ""; for ($i = 0;$i < 5;$i++) { $echostr .= "test"; } echo $echostr; I know that loop 2 will increase a bit the file size and therefore the user will have to download more bytes but If I got huge loop will it be better to use second loop or not? Thanks.

• Is there a canonical source for learning C# and .NET internals?

  - by ta269uec

  I have been a C++ programmer for last several years with a bit of C# here and there. In my latest job, I work heavily on C#. I picked most of my C# by following the code-base or random google searches on what I wanted to do at that point (like threading in C#). I feel a time has come to invest some time into understanding the language internals and also understanding the .NET framework from an architectural point of view. Can someone recommend the "gold standard" text/resource for accomplishing these? What about that resource makes it the best? What were your experiences with it?
