• Gnome/Nautilus does not remember individual folder's size/position?

  - by RaiGal

  I am using ubuntu 11.04 and I have noticed that Gnome/Nautilus remembers a "global" setting for size/position using the last window open instead of remembering an individual size/position for each folder. Also, this applies for some applications as well. I find this a real productivity killer and I think its one of the most basic features of a window manager. Funny thing is, that windows had this feature for a long time now. I have tried devilspie but I find it would be really time wasting to configure every folder that way. Is there any fix for this issue, if not what window manager would you suggest me? Thank you!

• Good analytics tools that can track visitor actions from a particular source?

  - by tnorthcutt

  Are there good tools that can track what actions a certain subset of visitors (i.e. from a particular source) do once they're on your site? As far as I know (which could be wrong), Google Analytics can't do this beyond telling you how long they stayed, bounce rate, and average number of pages. I'm looking for something that can tell me which links they clicked on, and if possible break it down per-visitor. Free solutions would be great, but I'm anticipating that this would require a paid solution.

• Becoming an expert vs boredom [closed]

  - by QAH

  I am a college student, and I love to program, period. I code all kinds of things in different kinds of languages. Although I enjoy programming, I have an extremely hard time sticking to one project for a long time. I attribute this shortcoming to my high level of curiosity, exploring different technologies, languages, libraries, etc. What would be best? Should I settle down more and spend time on becoming an expert in one or two programming fields, or should I be more of a jack of all trades, trying out all kinds of new technologies, languages, programming methods, etc.? I'm guessing that somewhere in the middle would be best. I'm always amazed at how many developers are able to create one or two projects, and develop on them for years. What techniques do you guys employ to help you stay focused on a project?

• How do I render an animation where some frames appear twice?

  - by hustlerinc

  I am animating a sprite. The sprite has 7 different frames, but the animation is 10 frames long. This is because 3 of the original frames appear twice in the animation: 3 -> 4 -> 5 -> 6 -> 4 -> 3 -> 2 -> 1 -> 0 -> 2 Frames 2, 3 and 4 appear twice. This avoids having to store duplicate frames in the spritesheet. How can I render the animation in this sequence with repeated frames?

• Create many similar classes, or just one

  - by soandos

  The goal is to create an application that has objects that can represent some operations (add, subtract, etc). All of those objects will have common functions and members, and thus will either implement an interface or inherit from an abstract class (Which would be better practice, this will be in C# if that matters?). As far as I can see, there are two different ways of organizing all of these classes. I could create an addition class, a subtraction class, etc. This has the upside of being highly modular but the difference between classes is so minimal. I could create one class, and have a member that will say what type of operation is being represented. This means lots of switch statements, and losing some modularity, in addition to being harder to maintain. Which is is better practice? Is there a better way of doing that is not listed above? If it matters, the list of functions that should be supported is long.

• How could your company's learning/development department best serve you?

  - by MTR

  I'll preface my question with a disclaimer - I am not an engineer, I'm just someone who works with them full-time, in a learning and development capacity. Given that, one of the comments I get regularly from the engineers I'm tasked with developing is that they feel that they're having solutions (both technical and non-technical) for development "pushed" at them vs. anyone from my field consulting with them to determine what they really need. So my question is - if you could give your company a list of the top 3-5 things they could do - in a classroom, or elsewhere - to develop meaningful skills that would help you be a better engineer, a better employee, and one more likely to STAY with the company for the long haul, what would make the cut and why? Thanks in advance for your responses.

• livecd won't boot 11.04

• 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.

• TGA loader: reverse y-axis

  - by aVoX

  I've written a TGA image loader in Java which is working perfectly for files created with GIMP as long as they are saved with the option origin set to Top Left (Note: Actually TGA files are meant to be stored upside down - Bottom Left in GIMP). My problem is that I want my image loader to be capable of reading all different kinds of TGA, so my question is: How do I flip the image upside down? Note that I store all image data inside a one-dimensional byte array, because OpenGL (glTexImage2D to be specific) requires it that way. Thanks in advance.

• What's the maximum filename length in encrypted ext4 partition?

  - by fdlm

  I'm using a two-partition setup with ubuntu (one partition for the system, one for my home directories). Until now I had an ext3 formatted home partition, which I'm currently trying to migrate to an encrypted ext4 partition. However, when copying the files the system is bugging me with errors, complaining that filenames are too long. As far as I could find out using wikipedia filename length is 255 bytes for ext3 and 256 bytes for ext4. So where's the problem, and how can I solve it? Thanks!

• What should I do if my text exceeds my text render target boundaries?

  - by user1423893

  I have a method for drawing strings in 3D that does the following: Set a render target Draw each character as a quadrangle using a orthographic projection to the render target Unset the render target Draw the render target texture using a perspective projection and a world transform My problem is how to deal with strings whose characters length exceeds that of the render target dimensions? For example if I have string "This is a reallllllllllly long string" and the render target can't accommodate it, it will only capture "This is a realllll". The render target (and its size) could be set each frame but wouldn't that be far too costly?

• Managing large downloadable content on mobile devices

  - by larromba

  This is a general question of how to best manage large downloadable content on mobile devices. Lets consider a situation whereby a mobile app needs to download a number of very large content items, like HD videos, that are over 500MB but under 2GB. Now, lets assume this content delivery system should be scalable. Would it be a fair assumption that: A reputable cloud service would be needed - if so, what is a reliable and cost effective cloud service for mobile devices based on anyone's experience? Large content downloads should only be attempted over a wifi connection, so the end user doesn't incur large costs, e.g. when travelling. Downloads should carry on in the background if possible, as the user won't want to wait in an app for long periods. If the downloads don't finish, or the OS quits the app, all downloads should carry on when the app is next activated? Are there any other pitfalls anyone may have experienced when managing large content on mobile devices? Thanks.

• Why google isn't updating my site title in search results? [closed]

  - by SharkTheDark

  Possible Duplicate: Google doesn't seem to update the description or title of my homepage I had my domain for few days before I uploaded site to it, and it had one title, and then when I uploaded content it should get new title, but with my misunderstanding of WordPress it had blocked robots.txt and keyword with no-index and no-follow. But I removed that like 7 days ago, and I see in reports that Google bot is crawling over my site, but my site title isn't updating, it still has old domain title when site wasn't there... My robots.txt has now: User-agent: * Allow: / I have clear title tag on every page. How long does it take to update? Do I need to check something else?

• Comment améliorer le temps de compilation pour C/C++ ? Apple propose un système de modules pour remplacer les en-têtes

  Comment améliorer le temps de compilation pour C/C++ ? Apple propose un système de modules pour remplacer les en-têtes Un des problèmes assez décriés des langages C et C++ est le temps de compilation, qui est un peu plus long. Cela est surtout dû à l'utilisation des en-entêtes (headers). Les développeurs d'Apple viennent de proposer un document assez intéressant qui introduit un système de modules pour C et C++ afin d'améliorer le temps de compilation. À titre d'exemple, Apple cite le minuscule code source de « Hello world » en C : quatre lignes de code seulement. Pourtant, le fichier d'en-tête nécessaire pour sa compilation est 173 fois plus grand que l'application elle-m...

• nfs mountpoint named ``share'' breaks ls and man

  - by freddyb

  I mounted a nfs server to ~/share. This works fine as long as I'm at home, where the nfs share is in reach. Whenver I'm not, this seems to break access to all manpages. Using man (or ls in my homedir) waits forever. Checking with strace reveals that they try to access the folder called share. Unmounting fails too. Even with -l (lazy) and -f (force). I am asking for three things here: Is ``share'' a magic name? Does something like MANPATH exist, which I should avoid? How do I unmount without rebooting? (I already commented the share out in fstab) What would you suggest me to do, to have network/position based mounting of NFS shares?

• Changing Workspaces changes active window

  - by puk

  I have a dual monitor setup, but I am sure it's the same with a single monitor. If I have two applications open, one is vim, the other is google chrome. Lets say the focus is on vim. If I switch to another workspace (ie. alt3) then switch back to that workspace (ie. alt1) now the focus is on google chrome. This process toggles indefinitely so long as I don't transition too quickly. Is there any way to prevent/disable this?

• If you need more than 3 levels of indentation, you're screwed?

  - by jokoon

  Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduct from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that dividing up a program into more function improves its design is a common thing taught at school, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• PASS Summit Location Redux

  - by andyleonard

  Introduction To quote Ronald Reagan, " There you go again ." The Professional Association for SQL Server (PASS) is considering locations for future PASS Summits. The apparent answer is: You Can Have The Summit Anywhere You Want... ... as long as it's in Seattle. PASS conducted a survey on this about a year ago, and I commented on the results and PASS' (mis-)interpretation of said results in a post entitled On PASS Summit Locations, Time Will Tell . "It's About Community" I think every member of the...(read more)

• "// ..." comments at end of code block after } - good or bad?

  - by gablin

  I've often seen such comments be used: function foo() { ... } // foo while (...) { ... } // while if (...) { ... } // if and sometimes even as far as if (condition) { ... } // if (condition) I've never understood this practice and thus never applied it. If your code is so long that you need to know what this ending } is then perhaps you should consider splitting it up into separate functions. Also, most developers tools are able to jump to the matching bracket. And finally the last is, for me, a clear violation to the DRY principle; if you change the condition you would have to remember to change the comment as well (or else it could get messy for the maintainer, or even for you). So why do people use this? Should we use it, or is it bad practice?

• Is it possible to save output from a command to a file subsequent the command already has been executed?

  - by NES

  Does an elegant way exists to save the output of a command subsequent to a file as long as the terminal window is open? I mean once the command has been executed in the terminal. The output is still there in terminal. Now i could copy & paste all the lines and save it to a file. But perhaps does a method exist to somehow write the output buffer of a terminal window to a file or even better the output of an already executed command?

• Updated version of Adobe Reader

  - by Joe_Kerr

  I'm not sure if this has been answered already...anyhow, I'm placing this question, so you could help. I've been a PC user for as long as I can remember, and I've just migrated to Ubuntu. So far the product has delivered the satisfaction I am expecting. However, there is one program that I'll need to ensure my productivity--an updated version of the Adobe REader. Is there any way I could get this program via Ubuntu, without using WINE? please let me know... thanks!

• How to Enable SideLoading in a SharePoint Site

  - by Damon Armstrong

  I was trying to deploy a SharePoint App for the first time and ran into an error about SideLoading not being enabled on the site. The solution is fairly simple – you just have enable the Developer feature on the site.  Unfortunately, it’s a hidden feature so you have to do it through PowerShell.  While searching the internet for the command to enable the feature I kept running into really long scripts that seemed overly complicated.  Fortunately, Jeff (a friend at work) sent me this snippet that is very concise and does the job: Enable-SPFeature e374875e-06b6-11e0-b0fa-57f5dfd72085 –url http://yoursharepointbox/site/ Obviously, you will need to update the URL to match your environment!

• Is there benefit to maintain a large project with bad code?

  - by upton

  I'm currently maintain a large project with more than 100000 LOC. The code use the MFC as its framework, in genral, it only has interface part which heavily use the mfc api and a business logic part which full of bad code, confusing logic. The company has some small features delivered to the customer each year(most features are adding code to exisiting project, finding some reference of some api or variable and it' s no different with fixing 3-4 bugs ), most of the tasks are to resove issue and optimize performance . Like other company with maintaining position, it value people who knows much logic about its product. There are people who can quickly finish the job on such project, is it worth to train myself like such a programmer? Is there benifits to work on such project for a long time?

• Is there a way to return a response every x seconds or so to a single http request?

  - by luis

  I'm wondering if it's possible to send a response every second or so to a single http request. Like for example the client makes an http request, then the server sends a space character every second. This could be never ending or with a limit, for example a minute. I think the word 'response' is misleading in this context, since I don't necessarily mean an http response. The whole http response could be composed of the space characters, which would mean a single http response to a single http request, except that it is a minute long. I tried chunked encoding but I don't think it works, or at least my implementation's wrong.
