• Gnome question> Nautilus only starts as root user

  - by user7978

  Hello. I am running Ubuntu 10.04 62-bit. When I attempt to start Nautilus from the command line, it does not appear -- although a PID is generated. As root/sudo, I can start Nautilus fine. One note: I run e16 as the windows manager, so I do not use Nautilus to draw my desktop. However, even under this configuration, Nautilus used to run fine as a "regular" user. The permissions for Nautilus are the same as the other packages in /usr/bin. I believe this is a Gnome issue, but I'm fumbling at this point.

• ManagementObjectSearcher error [migrated]

  - by Piotrek

  Some of our customers inform us that in some cases following error appears: System.Management.ManagementException: Blad dostawcy. at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext() The error is generated while trying to loop through a colection returned by Get() method of the System.Mamangment.ManagementObjectSearcher object. This is the code of my method: private bool PrinterExists(string printerName) { bool retVal = false; SelectQuery q = new SelectQuery("select caption from win32_printer"); using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(q)) { foreach (ManagementObject printer in searcher.Get()) { if(printer["Caption"].ToString() == printerName) { retVal = true; break; } } } return retVal; } It seems that the problem appears only on Windows XP. The only workaround I know is reconstruction of WMI database. It sometimes helps, but unfortunatelly not always. Can anyone tell me what is the reason of this error and how can I fix it?

• How to divide hex grid evenly among n players?

  - by manabreak

  I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

• Largest successful JavaScript project? [closed]

  - by 80x24 console

  A common theme in the GWT community is "I wouldn't want to build a project of THAT size using a pure JavaScript library!" What is the largest project that you have successfully delivered with frontend functionality written in JavaScript? (not Java or GWT) Please provide at least a hand-wavy SLOC estimate of the unique JS code (not including libraries, frameworks, toolkits, test code, generated code, server-side processing such as PHP, etc.) that was in the finished product. Note to GWT advocates: Please read the question carefully before answering. I've heard plenty of stories about JS failures and GWT successes, but I'd like to hear some quantified JS successes. Note to mods: This is primarily a business-of-software question, not a tools question. It factors into a real-world business decision.

• pop up html as javascript string instead of hidden div for seo [closed]

  - by user1324762

  Possible Duplicate: How bad is it to use display: none in CSS? I have heard that using display:none or visibility:hidden css properties are not a very good idea for seo purposes. I have about 4 different pop up windows to display and each one has about 20 words inside it. I can create hidden divs. Another option is to store div html elements as javascript string. In this way pop up html elements will be generated from javascript string. This will be still faster than using ajax since the data is static. Is this method absolutely safe for SEO? P.S.: I was just asking about similar question on http://stackoverflow.com/questions/12389075/storing-data-in-javascript-array-for-further-use, but this one is different, it is about static data and about SEO.

• Which CMS can I use for my project?

  - by Nicolás A.

  I have to build a new website for my client.. and he needs this stuff: A user generated content website.. where users can upload their own videos.. (i will use a video hosting platform with api like fliqz.com) I must manage a big user system.. where users can create their own "sub-users"... the site must manage paid subscriptions and payments through paypal.. and other payment gateways... So the question is.. i have to use a pre-built CMS and extend it.. or just a good framework? I've been thinking about joomla, drupal and expressionengine... It's not neccesary to use a open source cms... I've looking at drupal.. but is not as easy to understand and extend... Can anyone help me to make a good decision?

• Silverlight 4 + RIA Services - Ready for Business: Search Engine Optimization (SEO)

  To continue our series, lets look at SEO and Silverlight.  The vast majority of web traffic is driven by search. Search engines are the first stop for many users on the public internet and is increasingly so in corporate environments as well.  Search is also the key technology that drives most ad revenue.  So needless to say, SEO is important.  But how does SEO work in a Silverlight application where most of the interesting content is dynamically generated?   I will...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.

• Writing a spell checker similar to "did you mean"

  - by user888734

  I'm hoping to write a spellchecker for search queries in a web application - not unlike Google's "Did you mean?" The algorithm will be loosely based on this: http://catalog.ldc.upenn.edu/LDC2006T13 In short, it generates correction candidates and scores them on how often they appear (along with adjacent words in the search query) in an enormous dataset of known n-grams - Google Web 1T - which contains well over 1 billion 5-grams. I'm not using the Web 1T dataset, but building my n-gram sets from my own documents - about 200k docs, and I'm estimating tens or hundreds of millions of n-grams will be generated. This kind of process is pushing the limits of my understanding of basic computing performance - can I simply load my n-grams into memory in a hashtable or dictionary when the app starts? Is the only limiting factor the amount of memory on the machine? Or am I barking up the wrong tree? Perhaps putting all my n-grams in a graph database with some sort of tree query optimisation? Could that ever be fast enough?

• After one has made many grid based puzzles how does one make then into a PDF ready for printing

  - by alan ross

  After one has generated many grid based puzzles like sudoku, kakuro or even plain crosswords and now one has to print them in a book. How does one make a pdf (book file) from them automatically. To explain the question better. One has the puzzle ready in computer format like ..35.6.89 for all nine rows. The dot being the empty cell. How does one convert then to a picture on a PDF page complete with box, automatically without doing them individually and then print a book from the pdf file. As can be seen there are other things also printed on the page all this is done automatically.

• Languages with C/C++ output [closed]

  - by Vag

  Which languages have compilers able to emit plain standard C/C++ code? For a start: Haxe // uses Boehm GC Haskell (JHC) Haskell (old GHC) // -fvia-c, removed recently (emitted code is super ugly) Clay ATS Cython RPython (Shed Skin) // experimental RPython (PyPy) Python (Nuitka) // although author claims there are no speedups Common Lisp (ECL) COBOL (OpenCobol) Scheme (Chicken) APL // So far I've not found working implementation available for free download Ur/Web // GCC-specific output, and intended to be used only for web developments (included for completeness only) I'd like to build comprehensive up-to-date list but found only these ones so far. I've tested only Haxe and it works pretty well and quite fast. What about other ones? What is your expirience? How much ugly is generated code? Update. Any language chains (e.g. X - Scheme - C) will be perfectly OK as answer if its use is practical enough and suited for production use.

• What exactly is the build number in MAJOR.MINOR.BUILDNUMBER.REVISION

  - by A9S6

  What I think about Build Numbers is that whenever a new nightly build is created, a new BUILDNUMBER is generated and assigned to that build. So for my 7.0 version application the nightly builds will be 7.0.1, 7.0.2 and so on. Is it so? Then what is the use of a REVISION after the build number? Or is the REVISION part being incremented after each nightly build? I am a little confused here... do we refer to each nightly build as a BUILD? The format is mentioned here: AssemblyVersion - MSDN

• How to package a single text file into a .deb?

  - by Fluffy

  I'm trying to a make a simple .deb package, which would basically edit a config of another package I listed as a dependency. I added the required manipulations to the postinstall file. The problem is I can't find a way to package an example config, which should be copied and edited from the postinstall script. At the moment I just have a folder with the sample config, of which I'm creating a tar.gz and orig.tar.gz, then dh_make in that folder, edit the generated files and run debuild. However if I open the resulting .deb file with an archive manager, I can see that the sample file was not included at all.

• Android Dynamic 2D Map

  - by Deltharis

  My problem is, I want to create a 2D tiled map. Yes, I know it's been asked a lot. I've seen answers that propose the use of tiled however it only allows (or so it seems to me) to generate static maps that do not change once generated. And I need a large empty uniform space of empty tiles, upon which players may place various buildings (some spanning more than one tile and logically being the same one). How to approach this in Android? Do I make some kind of TableLayout, use arbitrarly large amount of rows and imageviews (with my emptyTile), than somehow work event-based changing of image ids from there? I'd think that only a portion of that map should be visible at a time, but I don't see how scrolling around could be the part of that structure.

• How to make Facebook like button narrower than 225px?

  - by tog22

  I'm generating a like button with Facebook's 'standard' layout for my site via https://developers.facebook.com/docs/reference/plugins/like/ . I've set its width to 200 pixels, but notice that setting it to lower than 225 pixels has no effect, and the documentation on that page indeed specifies 225px as the minimum width for the standard layout. Unfortunately I need to make it 200 pixels wide to fit my site's design. Is there any way to force it into this width? (The site's at http://gwwc2.centreforeffectivealtruism.org/ if you want to have a play with Firebug, though the like button gets generated by javascript so you'd probably have to duplicate that page and edit its source.)

• How to display a projectile trajectory in c++? [on hold]

  - by sana

  I am trying to make a game of Gorillas in c++ whose specification is somewhat like....... is : "In this game both players should select their position on a level scaled ground. Scale of the ground should be from 0 to 20 divisions, each division corresponding to 10 meters. Each player will enter an angle and initial velocity (limits of both should be defined) and the player will hurl a stone with this velocity at given angle. Stone will make a projectile and if it hits the other player then shooting player wins. A random effect of air should also be incorporated. Air will support one player and resist other. Velocity of air should be generated randomly, within some limits, and subtracted or added in the horizontal velocity of the stone. An arrow of suitable length shall represent air direction and velocity. The player who hits first wins." How do I display the trajectory of the stone????

• Convert Microsoft Word documents (.doc/x) into HTML files

I bought Word Cleaner but the results are merely sufficient and I need go over all the generated html files to clean tons of useless injected tags like <strongH</strong<strongell</strong<strongo </strong<emWor</em<emld</em Most of the articles displayed on a website I manage are based on documents written on MS Word by people how has little idea of what are margins for or ordered/unordered lists, foot/end notes etc and I cannot make them use something else. Does anyone has a tip to help me handle those pages more efficiently than going over them to correct and apply my CSS style ? NB: Just for the record, using "Save as HTML DOC" in Word is faaar worst than Word cleaner

• FatCow and iPage real deal?

  - by Tribbey

  I need a cheap host that I can upgrade if needed for a startup. From searching, FatCow and iPage seem reliable and inexpensive web hosting services with a Unix OS and good bandwidth + disk space. I suspect they were bought from the same company. They propose to offer unlimited bandwidth/disc space and perks like AdSense/Facebook credit however, they're packages range from 1-3 years @ 3.15 USD/mo, there isn't a monthly package but they do allow you to cancel at anytime and there servers run on wind-mill generated energy which is a plus. I was suspicious because I couldnt seem to find one negative review about them, just affiliate pages until I read a review explaining they're strict policies on copywritten data. Has anyone experience with one of these two hosts?

• Do unused vertices in a 3D object affect performance?

  - by Gajet

  For my game I need to generate a mesh dynamically. Now I'm wondering does it have a noticeable affect in FPS if I allocate more vertices than what I'm actually using or not? and does it matter if I'm using DirectX or OpenGL? Edit Final output will be a w*h cell grid, but for technical issues it's much easier for me to allocate (w+1)*(h+1) vertices. Sure I'll only use w*h vertices in indexing, and I know there is some memory wasting there, but I want to know if it also affect FPS or not? (Note that mesh is only generated once in each time you play the game)

• Powermapper alternatives and google analytics?

  - by rugbert

  Whats a good application to map the hierarchical structure of a website and maybe get some google analytic action going on? Powermapper is pretty expensive and the trial version didnt seem particularly good at importing google analytics CSV files as advertised. In fact, out of the 1000 pages mapped, exactly 0 were successfully imported. I dont really need all the features Powermapper offers anyway, so the price tag is a bit much. All I really need is like, a simple visual representation of my (automatically generated) site structure (like a hierarchical site structure) and the ability to integrate my google analytic stats (page views mostly) with it.

• Using PhysX, how can I predict where I will need to generate procedural terrain collision shapes?

  - by Sion Sheevok

  In this situation, I have terrain height values I generate procedurally. For rendering, I use the camera's position to generate an appropriate sized height map. For collision, however, I need to have height fields generated in areas where objects may intersect. My current potential solution, which may be naive, is to iterate over all "awake" physics actors, use their bounds/extents and velocities to generate spheres in which they may reside after a physics update, then generate height values for ranges encompassing clustered groups of actors. Much of that data is likely already calculated by PhysX already, however. Is there some API, maybe a set of queries, even callbacks from the spatial system, that I could use to predict where terrain height values will be needed?
