• How can I force X to start in a computer without a monitor?

  - by Javier Rivera

  I have I computer that have no monitor attached. When I boot it X fails to start because there is no monitor detected. If I boot it with a monitor attached and after X is started I remove the monitor everything works fine. Details and Background: This computer is a kind of hardware consolidation server. It's only purpose is to run two Virtual Box VM's that run Windows XP and some important but seldom used (once or twice a month) programs. For a couple of time it has been lying in a corner with an old monitor attached to it and working great. But space in the office was getting scarce and I moved the computer to the server room. There is no monitor attached to it there (no space), and sometimes the computer is rebooted. When it boots without monitor X is not started, the vms don't start and I get called to solve the problem.

• How can I remove gradients from Elementary theme?

  - by John

  I really don't like the gradients in the Elementary theme and I was wondering if there is a way to remove them from applications like Nautilus-Elementary, Postler, Dexter, etc. I've tried commenting out the Apps/[Application].rc in /usr/share/themes/elementary/gtk-2.0/gtkrc but it doesn't work. It still leaves the gradients in their place. I'm a big fan of the other controls in the theme: the scroll bar, the way it borders gedit and the buttons, and I'd like to keep these features, but I don't like the way it styles its windows. EDIT: The gradients I'm talking about are the ones at the top of the window. Some examples: Nautilus-Elementary: Postler: Rhythmbbox: Transmission: I'd like to create a sort of matte look, similar to this, which was done using Orta: Nautilus-Elementary: Postler: Rhythmbox: Transmission: I'd like a flat color, preferably without the line separating the top part of the application with the bottom.

• Any good tutorials all this web programming stuff for a GUI person? [closed]

  - by supercheetah

  For some reason, I am having a hard time understanding all this web programming stuff--from AJAX to JSON, etc. I've got plenty of experience programming GUIs. I'm currently working on a project in Python, and I thought that maybe I could just use PyJS (since it's GWT for Python, it uses an API that's very familiar to experienced GUI programmers like myself) to compile it with a Javascript interface on top, but alas, the compiler gave me a spectacular failure. It's obviously not meant to handle much of any Python beyond itself, and some of the core Python library. It would have been nice if it could, but I will admit, it would have been the lazy way to do it. I tried to learn Django, but for some reason, I'm just having a hard time understanding the tutorial on their website, and what it's all doing. Maybe it's not the best framework to learn, perhaps? Anyway, does anyone have a good primer/tutorial explaining all this stuff, especially for Python, and especially for someone coming from a GUI background?

• Starting a career in quantitative finance

  - by Vitor Braga

  I've been reading John Hull book (Options, Futures and Other Derivatives) mostly on curiosity. I've read other books about financial markets in the past (like Elder's Trading for Living and the novel Reminiscences of a Stock Operator). But I'm really hooked by the John Hull book. My background is mostly scientific computing: number crunching, visualization and image processing. Mostly in C++, with some C, Fortran, Python, Ruby here and there. I've been thinking on moving on to quantitative finance - I'd like to do that. What would be the best way to start? Any tips?

• How should programmers handle email-username identity theft?

  - by Craige

  Background I recently signed up for an iTunes account, and found that somebody had fraudulently used MY email to register their iTunes account. Why Apple did not validate the email address, I will never know. Now I am told that I cannot use my email address to register a new iTunes account, as this email address is linked to an existing account. This got be thinking... Question How should we as developers handle email/identity theft? Obviously, we should verify that an email address belongs to the person it is said to belong to. Why Apple did not do this in my case, I have no idea. But lets pretend we use email address for login/account identification, and something slipped though the cracks (be it our end, or the users). How should we handle reports of fraudulent accounts?

• Firefox 4 on 10.10

  - by Oxwivi

  I installed Firefox 4 from the daily builds PPA, and it doesn't seem to be the latest RC, and tells me that I'd better update to it. How come a daily build is behind snapshot releases like beta or RC? I used the profile for my Firefox 4 on Windows, and the Global Menu (or whatever it's called) has gone to the right side. I had a few app tabs saved in the profile. What gives? How do I get the Global Menu to be orange or whatever color it's supposed to be? How do I pin it to Unity? Update Global Menu back on left side after restoring toolbar to defaults. However it's noteworthy that I could not drag it to the other side while the customization window was open unlike the other elements.

• OpenGL ES Basic Fragment Shader help with transparency

  - by Chris

  I have just spent my first half hour playing with the shader language. I have modified the basic program I have which renders the texture, to allow me to colour the texture. varying vec2 texCoord; uniform sampler2D texSampler; /* Given the texture coordinates, our pixel shader grabs the corresponding * color from the texture. */ void main() { //gl_FragColor = texture2D(texSampler, texCoord); gl_FragColor = vec4(0,1,0,1)*vec4(texture2D(texSampler,texCoord).xyz,1); } I have noticed how this affects my transparent textures, and I believe I am loosing the alpha channel which would explain why previously transparent area's appear totally black. If I use the following line instead, I am shown the transparent area's gl_FragColor = vec4(0,1,0,1)*vec4(texture2D(texSampler,texCoord).aaa,1); How can I retain the transparency after this modification to the colour? I have seen various things about a .w property, and also luminous, but my tweaks with those and the .aaa property are not working XD

• How To Delete, Move, or Rename Locked Files in Windows

  - by Chris Hoffman

  Windows won’t allow you to modify files that open programs have locked. if you try to delete a file and see a message that it’s open in a program, you’ll have to unlock the file (or close the program). In some cases, it may not be clear which program has locked a file – or a background process may have locked a file and not terminated correctly. You must unlock the stubborn file or folder to modify it. Note: Unlocking certain files and deleting them may cause problems with open programs. Don’t unlock and delete files that should remain locked, including Windows system files.

• I need a webpage to host my javascript!

  - by Amir Reza

  Does anyone know a website that hosts javascripts on their page? I have a research project that needs to collect some RTT from all over the world and compare them together. I have written the javascript code for that but I do not have a high hit rate website to put it on to collect data. I know it is a little bit odd question to ask, but do you know any website or any trick that can help me? Note that the script would not do any harm to anybody! :-) Thanks, Decad is right, I basically need some people to put my script on their "high-hit rate" website ... so I can collect data from large number of clients... Of coarse, the script is run on the background with no harm to the page. It basically measures some RTT and submit it to a server. I already have some pages, but they barely got a hit from outside! Thanks,

• Working as an entry .Net Developer in the USA [closed]

  - by Abdullah

  I just have a question about .net entry level jobs in VA. I am a master degree student in field of software engineering but I am graduated from department of physics. I decided to work on Java first, but I have changed my mind because I don't have any Java programming background except Java class in master degree so I decided to work on C# because it was easy to me to work with Visual Studio and it's fun to me to work with SQL database and HTML stuffs. And I am a member of a IT consultant company in Reston where I took course from there about .net and I created online recruitment system for their web site. Now I am applying for CPT (internship) but I didn't work in a company as a .net developer so I don't have experience. Here is my question. If I get CPT and find a job, what do software companies want from an entry level .net developer? and what do they ask as interview questions?

Im doing a project for the university for storing baseball players statitics, but from baseball data I have to calculate the score by year for the player who is beign displayed. The background is, lets say 10, 000 users hit the player "Alex Rodriguez", the application have to calculate 10, 000 the A-Rod stats by years intead of just read it from some where is temporal saved. Here I go: What is the best method for caching this type of data? Do I have to used the same database, and some temporal values on the same database, or create a Web Service for that?

• How to find Sub-trees in non-binary tree

  - by kenny

  I have a non-binary tree. I want to find all "sub-trees" that are connected to root. Sub-tree is a a link group of tree nodes. every group is colored in it's own color. What would be be the best approach? Run recursion down and up for every node? The data structure of every treenode is a list of children, list of parents. (the type of children and parents are treenodes) Clarification: Group defined if there is a kind of "closure" between nodes where root itself is not part of the closure. As you can see from the graph you can't travel from pink to other nodes (you CAN NOT use root). From brown node you can travel to it's child so this form another group. Finally you can travel from any cyan node to other cyan nodes so the form another group

• How much is modern programming still tied to underyling digital logic?

  - by New Talk

  First of all: I've got no academic background. I'm working primarily with Java and Spring and I'm also fond of web programming and relational databases. I hope I'm using the right terms and I hope that this vague question makes some sense. Today the following question came to my mind: How much is modern programming still tied to the underlying digital logic? With modern programming I mean concepts like OOP, AOP, Java 7, AJAX, … I hope you get the idea. Do they no longer need the digital logic with which computers are working internally? Or is binary logic still ubiquitous when programming this way? If I'd change the inner workings of a computer overnight, would it matter, because my programming techniques are already that abstract? P. S.: With digital logic I mean the physical representation of everything "inside" the computer as zeroes and ones. Changed "binary" to "digital".

• Mobile 3D engine renders alpha as full-object transparency

  - by Nils Munch

  I am running a iOS project using the isgl3d framework for showing pod files. I have a stylish car with 0.5 alpha windows, that I wish to render on a camera background, seeking some augmented reality goodness. The alpha on the windows looks okay, but when I add the object, I notice that it renders the entire object transparently, where the windows are. Including interior of the car. Like so (in example, keyboard can be seen through the dashboard, seats and so on. should be solid) The car interior is a seperate object with alpha 1.0. I would rather not show a "ghost car" in my project, but I haven't found a way around this. Have anyone encountered the same issue, and eventually reached a solution ?

• After the upgrading to 13.10, I can't input Japanese and Chinese in Emacs

  - by oda

  I have just upgraded Ubuntu from 13.04 to 13.10. It seems iBus have been made big changes.Then I just go to system setting - text entry settings - add "Chinese pinyin" and "Japanese anty" input method. It works well when I input Chinese or Japanese in terminal or .txt file. But when I want to input Chinese and Japanese in Emacs. Even though I have enable ibus-mode in the buffer and change to Chinese pinyin or Japanese anty input method. It just output the English word. Below is the ibus configure in .emacs.By the way, It works well before I upgrade Ubuntu to 13.10 and Emacs to 24.3.1. (add-to-list 'load-path (concat my-emacs-path "/ibus-el-0.3.2")) ;;(setq ibus-python-shell-command-name "python2.7") (require 'ibus) ;; Turn on ibus-mode automatically after loading .emacs (add-hook 'after-init-hook 'ibus-mode-on) (setq ibus-cursor-color '("red" "blue" "limegreen"))

• Why aren't tangent space normal maps completely blue?

  - by seahorse

  Why aren't normal maps just blue? I would think that normal maps should be predominantly blue in color because the Z component of the normal is represented by blue. Normals point out of the surface in the Z direction so we should see blue as the predominant colour since the Z component is dominant. By definition tangent space is perpendicular to the surface. At any point we should have the normal always pointing in the Z (blue direction) with no X (red direction) or Y (green direction). Thus the normal map (since it is a "normal map") should have the colour of the normals which is just blue (R = x = 0, G = y = 0, B = z = 1) with no shades in between. But normal maps are not so, and they have gradients of shades in them. Why is this so?

• Some Adsense domain's ads are causing document.write() statements that remove the html from the page

  - by er1234

  All that is output on the page is the domain name of the advertiser, for example 'www.solar-aid.org'. The rest of the content is stripped, I believe because of a document.write() statement. I'd like to know if this is a common issue or something wrong with our setup. There are three domains causing the issue, which we've blocked from Adsense as a result. solar-aid.org kiva.org grameenfoundation.org Given the type of organizations I think they may be within the default group of 'public service ads' within the Backup Ads setting. If the issue doesn't completely resolve itself soon (one customer of ours complained today, even though I blocked them 5+ days ago), I'll disable public service ads and select the 'fill space with a solid color' option.

• Why is C++ predominant in programming contests and competitions?

  - by daniels

  I understand that C++ is a very fast language, but ain't C just as fast, or faster in some cases? Then you might say that C++ has OOP, but the amount of OOP you need for most programming puzzles is not that big, and in my opinion C would be able handle that. Here's why I am asking this: I am very interested in programming contests and competitions, and I am used to coding in C on those. However, I noticed that the vast majority of people use C++ (e.g., 17 out of 25 finalists on Google Code Jam 2011 used it, while no one used C), so I am wondering if I am at a disadvantage going with C. Apart from the Object Orientation, what makes C++ a more suitable language for programming competitions? What are the features of the language I should learn and use to perform better on the competitions? For background, I consider myself pretty proficient in C, but I am just starting to learn C++.

• What terminal emulators are available for heavy terminal users?

  - by Noah Goodrich

  I spend a lot of time at the command-line during the workday and at home too since I run Ubuntu exclusively. I've been using the default gnome terminal but I've reached a point where I'd really like to get my terminal tricked out so that my common tasks are as easy as possible. Specifically, I find that I spend of lot of time browsing code in the terminal and working in config files. On my wish list would be: Ability to have multiple screens, tabs, windows (I don't have a preference at this point) that I can easily switch between. Color coding for everything Easy to modify the aesthetics of the terminal (is it vain to want my terminal to look nice?) such as transparency, borders, etc.

• What are the most important concepts to understand for "fluency in developer English"?

  - by Edward Tanguay

  In April, I'm going to be giving a talk called **English 2.0 - Understanding the Language of Developers" to a group of English teachers. The purpose is in two hours to give them a quick background in key concepts so that they can better understand developer blogs and podcasts and are able to ask better questions when talking to developers. What do you think are the most important concepts to understand, concepts that developers take for granted but the general public is not familiar with? Here are a few ideas: version control abstractions pub/sub push vs. pull debugging modularity three-tier architecture class/object "spaghetti code" vs. OOP exception throwing crowd sourcing refactoring the cloud DRY - don't repeat yourself client/server unit testing designer/developer

• What kind of screen has the best image quality for reading/programming?

  - by EpsilonVector

  I'm thinking about buying a new laptop, and while I bought my original one oblivious to the fact that there could be different quality screens out there, after seeing the screen on my sister's netbook I realized that I might have to be cautious with my next purchase. Granted, I did not confirm that the reason my sister's screen looks the way it does is due to the screen itself and not color scheme/graphics card, but I know very little about the different screen technologies and how they differ in image quality and therefore can't really tell if wondering about it even makes sense or not. So what I'm asking is: should I be worried about screen quality? And if so, what technologies should I be looking for? How do they differ and which are the best ones? What are the different elements that determine the quality of a screen and which stats should I go for in each element? For the record, I'm not interested in opinions about screen size, but picture quality for lots of reading/coding.

• How are buttons made to be clicked?

  - by Johnny

  I just want to ask a general question. According to that answer, Ill continue thinking. You know in games there are lots of clickable items. Play button, exit, comboboxes maybe etc. My question is are those buttons drawn in same canvas with background and all other things, or for every different thing there is another canvas object? My question is about for general. Im not asking about a specific game, im asking how they are made generally. Im planning to start a game on Android, and Im confused actually how to design buttons, and other object. Probably Im going to use View/SurfaceView for now. I don't have much experience with OpenGL yet. Thanks in advance.

• Spending the summer at camp Web Camp, that is

  Microsoft is sponsoring a series of Web Camps this summer. Theyre a series of free two day events being held worldwide, and Im really excited about being taking part. The camp is targeted at a broad range of developer background and experience. Content builds from 101 level introductory material to 200-300 level coverage, but we hit some advanced bits (e.g. MVC 2 features, jQuery templating, IIS 7 features, etc.) that advanced developers may not yet have seen. We start with a lap around ASP.NET...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.
