• Evolution and thunderbird sharing same mail data?

  - by balki

  Hi, I have been using Evolution for a quite long and it has downloaded around 1.6GBs of mails from gmail. I want to try thunderbird but I dont want to re download everything again. Is that possible to have both clients sharing same data? I'll make sure I don't use both at the same time if that matters. I'll move to thunderbird fully if I'm happy with it. Problems I face with evolution is that I have to have the GUI running always if I want to get instant alerts and send mail immediately. Also it loads the messages slow and even after I move to the next mail, it slowly downloads all the linked images before moving on.

• Web-based data generator

  - by John Paul Cook

  One of my coworkers told me about Mockaroo , a web-based data generator. I needed some test data for upcoming blog posts, so I decided to give it a try. It’s pretty good. I had to use Firefox because of problems running Mockaroo on Internet Explorer 11. Using the defaults except for changing the format to SQL, it generated output that looked something like the following. Mockaroo is so good that it generates fake data that could accidentally be real, such as email addresses. Consequently, I edited...(read more)

• RewriteRule working local but not on remote server

  - by m0tv

  I have a .htaccess file with one simple RewriteRule: RewriteEngine on RewriteRule ^([A-Za-z0-9-]+)$ ?site=$1 I want to have an url like http://www.example.com/imprint and forward it to http://www.example.com/?site=imprint I checked this rule with an RewriteRule tester which gave me the results I want to achieve. On my local development system it works well too. But on a remote server the URLs just give me a 404 error. Other more simple rewrite rules are working with no problems, so everything must be set up correctly (I think..). The problem is that I don't have access to any error logs or the server configs. So the only thing I can do is to guess... Can anyone tell me if theres something wrong with this rule? Or anything else I can do or test to solve this? Or has someone an idea what could be wrong on the server?

• svn-based versioning tool, problem with network timeout

  - by Scarlet

  My dev team was committed a versioning tool based on Subversion to run on Windows (our svn client is sliksvn). We're developing with Delphi XE2, should that matter. We're asked to implement a "check for updates availability" feature, which has to work as follows: Connect to the SVN repo via svn+ssh protocol; See if there are changes to receive and list them; Let the user decide if he wants to receive changes or not. We don't have a great knowledge on svn, so we thought to implement that thing client side by a certain number of CreateProcess calls that wrap directly proper svn commands. Anyways what we perceived is that if network problems should arise, such like a connection drop, svn client hangs forever waiting for the operation to close instead of failing for timeout. We know that CreateProcess can be given a timeout argument, but it wouldn't be correct to use it, as we can't know from outside how long will be the svn operation taking to complete. Is there any way to avoid that deadlock?

• Mastering the Art of SEO

  As the name indicates this article is based on one of the very advance concept nowadays which is none other than SEO which stands for Search engine Optimization. Some years back people were concerned only about the main problems or issues of a particular subject matter. But due to the advancements in technology and specifically internet, things have changed a lot. Now each matter is observed and analyzed very deeply and that is the reason that we are getting better results nowadays. One such thing, which has gained the status of universal fame as well, is internet.

• Online architecture guide

  - by hunterman

  I am a newbie in gamedev, and I don't know about programmer's problems that can appear during development. So can you advice me some best practice for starting build new online multi-player game backend? I just saw reddraft server, and I think Spring library can also do some of its features. What is big difference? Do I need learn more spring or I have to use servers like reddraft or write these tools myself? I know that I need to learn hard and many - and the question is - what I should to learn now at the beginning? Thanks.

• Live CD won't start with UEFI

  - by skytreader

  I'm trying to dual boot my Windows 8 machine with Ubuntu 12.04 but I cannot even get to the Live CD under UEFI. I've already set my UEFI boot loader to load from the DVD drive before anything else but it keeps on loading Windows 8 first thing. I've checked that the Ubuntu installer I am using is working by setting the BIOS to legacy boot; under this setting, I can get to the Live CD but it cannot detect Windows 8---something I do not want to happen. Just for the record, my boot order is as follows: ATAPI CDROM: HL-DL-ST DVDRAM GT51N USB CDROM: USB FDD USB HDD HDD: TOSHIBA [SERIAL NUMBER] Network Boot-IPV4: Network Boot-IPV6 Windows Boot Manager Has anyone ran into the same problems as me for UEFI? What am I missing here?

• What failure can kill a long running IRC client? [closed]

  - by Xeoncross

  I have an IRC bot that I built in PHP using sockets that attempts to run forever and (if disconnected) reconnects again. I have it listening to several channels. Apparently it's fairly resilient, because it can run for several days before the process ends and CRON has to start it up again. However, based on the fact the process ends I'm assuming there are other conditions I'm not accounting for that are causing problems. I have nothing in my error logs giving me a hint. In addition, sometimes the process will continue running - but I notice it's no longer present in any of the channels on the IRC server which makes me think it violated some part of the protocol. I have logic setup to handle: reply to PING's correctly reconnect on disconnect (and reconnect to channels) respond to private messages (so someone doesn't ban it) prevent memory leaks What other failure could be killing my long-running IRC client?

• Too much to learn, so little time

  - by Phobia

  Okay, so I'm a java developer (or at least I think I am),and also a student at the same time I want to get a job when I graduate,I'll be graduating in a year or so (hopefully) (Note: my major has nothing to do with programming) Now, I'm between a rock and a hard place I also want to nail the foundations to become a good software developer. I want to be able to write programs that solve problems,not just glue code The software market in my country for java developers is just a few developers working with Java EE (struts,spring,hibernate....etc) I'm currently learning C++ with this book. I've also watched most of the 1st lecture of this course and I understood pretty much everything I watched To sum it up, I have three options Learn Java EE Learn C++ Learn Scheme Which is better for me at this point?

• 12.04 Install Freeze, Blank Cursor Page

  - by smmilke

  I have been trying to install Ubuntu 12.04 via a live CD and most recently with the windows installer I found on line. The windows installer seemed to be working; I selected the partitioned portion of the drive on which to install Ubuntu and started the install process. The process freezes on a page with a flashing cursor and nothing else displayed. I have read about similar problems but have not been able to implement any of the solutions people have discussed. Any ideas on what might be hanging up the process, or how to get a better idea of what is causing the problem would be helpful. If anyone has had this problem and has a solution it would be GREATLY appreciated!

• Gnome shell crashing in 11.10 with 'purple haze' effect

  - by Andy

  I've just got Gnome with 11.10 up and running with my netbook and liked it so much I thought I'd get my parents old machine sorted with Ubuntu too. Unity works fine but when I try to switch to Gnome shell, I get problems. On login, the wallpaper appears as normal but then the colour bleeds out from the centre, leaving traces of it around the edge in a purple haze (yes, I do like Jimi Hendrix but I'm not making this up). When I go to applications, typing then pressing enter in the search field dumps me out so there's nothing but File / Edit / View etc in top left; starting a program seems to work but then there's only a white screen and no program window. Gnome classic works fine, from the limited use I've given it. I'm using an Asus desktop with ABIT motherboard, 2.6ghz with 1gb RAM; I've checked drivers and it says I'm up to date, Nvidia graphics. Anyone any ideas?

• Is Wordpress a good CMS for a Event Site? [closed]

  - by Roland

  I plan on building a gallery/exhibition event site. so Locations are usually always the same an fall into 3 categorys (gallery, offspace, institution). then there is the Exhibition title the date and the participating artists. So I was wondering if Wordpress could handle such a site. it should be very data driving though, so all the information is in a list view on one site and can be ordered and queryed (which artists took part in which exhibitions and so on) Please tell me the cons and pros of using Wordpress for such a site and problems I could run into if I might plan to broaden the scope later on. thanks!

• Part-time work as a beginner programmer [on hold]

  - by Valentas

  I wrote to one company near my university (starting in September) and they responded that they will probably hire me from the work I have already done (some projects and Euler problems solving). It's for 15 hours/week or so in order to not fall behind uni work. They require Python, SQL, XML and a good idea about how the Web works. The job role involves acquiring data from the Web and supplying it as search results for flight seekers (people). I am eager to learn but still, what can I do to become prepared for this? I ask because I tend to gravitate from one technology to the other, trying out things but never mastering it properly. What Web technologies are involved in such a job role? I have two months and want to learn as much as possible because there is much info but I have no idea where to start.

• AMD Catalyst diskless cluster

  - by Nathan Moos

  I'm using Ubuntu 13.10 to set up a diskless compute cluster. When I use the procedure detailed in https://help.ubuntu.com/community/DisklessUbuntuHowto, I successfully am able to boot all four nodes. However, once I install Catalyst, I immediately have problems: only one diskless node boots properly, with the other two hanging while attempting to start X. My assumption is that my Catalyst build was somehow specific to the node which I booted from first, which somehow prevents the other nodes from loading Catalyst. Can anyone provide hints to help solve this? Thank you in advance!

• Conky window jumps to the top

  - by Scott Severance

  Occasionally, my Conky window jumps to the top and covers all other windows. The only way to solve it is to kill and restart Conky. This happens at seemingly random times while using Compiz features. It seems especially common while using the scale plugin's window picker, but no plugin consistently causes this problem every time. I've seen several questions that appear related on the surface. However, all those questions are solved by ensuring that Conky starts after Compiz. In my case, my problems occur even if Conky starts after Compiz.

• Broken Links in different browsers

  - by kdorival

  Hi I'm having problems with our website, http://www.accessiblehomehealthcare.com, which is a wordpress 2.7 (version). All of a sudden our RSS links broke on the right side, which has happened before and I fixed it within 5 mins. Now, when I fix it, it doesn't look right in different version of I.E. or Firefox, I have I.E. 8 and Firefox 3.6.15 and it looks good for the most part, but there are a few parts where the links are broken. One browser the links would look ok but go to another page and the links or logos would be broken. Certain parts of the website should be static(identical) to the other pages of the site, but if a link is broken on one page, its perfect on another page. I was wondering was there a secret code for wordpress to keep the sites compatible with all browser versions or is there a bigger issue???? Any help or suggestions will help???

• Should I use float, double, or decimal for stats, position, etc?

  - by Ryan Peschel

  The problem with float and double is that they are not exact. If you are to do something like store replays, the values would have to be exact. The problems with decimal is that they are approximately 16x slower (confirmed by searching and personal testing) than floats and doubles. Couldn't Vector2s be another problem because they use floats internally for all the components? How do other games solve this problem? I'm sure they must use floats and doubles but aren't they not deterministic across platforms and different architecture? The replay files for games like SC2 run in a linear fashion so you cannot skip ahead so how do they solve the determinism issue with floating point numbers?

• Windows Phone 7 Design Template

  Windows Phone 7 Design Template Expression Blend is a wonderful design environment for WP7 (Windows Phone 7) but for quickly visualizing a concept nothing beats Illustrator! I am excited about WP7 and decided that having a solid .ai template would prove invaluable. Some of the details of the WP7 UI Design and Interaction Guide are a bit fuzzy (literally) but I was able to generate some useful layout guides, character styles, and symbols. While the template does not cover every aspect of the guide I think it is a good launching point; if you find it useful and extend it please share your updates (I created the template in CS4, if you have problems in earlier versions let me know).Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How to detect GLSL warnings?

  - by msell

  After compiling a shader with glCompileShader, I can call glGetShaderiv with GL_COMPILE_STATUS to check if the shader compiled successfully. I can also call glGetShaderInfoLog to get information about possible errors, warnings or other info. The information log returned by this function is unspecified. In a tool where users can write their own shaders, I would like to print all errors and warnings from the compilation, but nothing if no warnings or errors were found. The problem is that the GL_COMPILE_STATUS returns only false if the compilation failed and true otherwise. If no problems were found, some drivers return empty info log from glGetShaderInfoLog, but some drivers can return something else such as "No errors.", which I do not want to print to the user. How is this problem generally solved?

• Why is cleverness considered harmful in programming by some people?

  - by Larry Coleman

  I've noticed a lot of questions lately relating to different abstraction techniques, and answers saying basically that the techniques in question are "too clever." I would think that part of our jobs as programmers is to determine the best solutions to the problems we are given to solve, and cleverness is helpful in doing that. So my question is: are the people who think certain abstraction techniques are too clever opposed to cleverness per se, or is there some other reason for the objection? EDIT: This parser combinator is an example of what I would consider to be clever code. I downloaded this and looked it over for about half an hour. Then I stepped through the macro expansion on paper and saw the light. Now that I understand it, it seems much more elegant than the Haskell parser combinator.

• Unstable Wifi and Spontaneous Low-graphic Error with Pavilion DV4

  - by Constant Dean

  I've been having numerous problems with connectivity through WiFi. It had been working for a few days and now it doesn't. On top of that around 40% of every time I turn on the laptop it shows "System running in low-graphics" error and I'm unable to view the desktop (sometimes not even able to access terminal), therefore having to manually power-down until it finally works.
