• 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.

• does eCryptfs support multiple users?

  - by new to eCryptfs

  I'm new to ecryptfs and I need some clarification on how it works. Suppose there are two root users userA and userB, If I mount some folder under userA: [userA@Dev] $ mount ecryptfs real img now I can visit the img folder to access decrypted data. My questions is: While userA is still in log in state. Can userB login and access the decrypted data? This is currently what I observed on my local machine, but I'm not sure if it was cause by my misconfiguration. If it is the case, how can I avoid other users from accessing the decrypted data while userA is in login state?

• Ubuntu 14.04 and Dell E6440 - sound and mouse working after suspend/resume

  - by slawek.mikula

  I've installed fresh Ubuntu 14.04 on Dell Lattitude E6440 and i've encountered two strange issues when doing full system start/restart: - mouse scroll when full restart is working very fast. One turn of the wheel cause very large change of value (window scroll, sound change etc.) But when i suspend and resume laptop it starts working correctly (one turn of the wheel and small change of value - the same as in previous versions of Ubuntu) - sound from speakers - the same issue. When full restart the sound does not come from internal laptop speakers. It works though through headphones. After suspend/resume internal speakers starts to work. What can be a cause of these issues ?

• Building Paths Fluently

  - by PSteele

  If you ever need to “build” a path (i.e. “C:\folder1\subfolder”), you really should be using Path.Combine.  It makes sure the trailing directory separator is in between the two paths (and it puts the appropriate character in – DirectorySeparatorChar).  I wanted an easier way to build a path than having to constantly call Path.Combine so I created a handy little extension method that lets me build paths “fluently”: public static string PathCombine(this string path1, string path2) { return Path.Combine(path1, path2); } Now I can write code like this: var dir = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) .PathCombine("Folder1") .PathCombine("Folder2"); Technorati Tags: .NET,Extension Methods,Fluent

• Problem with Bash script: 'declare: not found'

  - by Ashfame

  I had a script which was running fine but when I ran it today, it says declare: not found. I am using bash shell and path at the starting of the script is correct. Two flagged lines in my script are as follows: declare -a RESPONSE RESPONSE=($RESULT) It also says ( is unexpected but I guess that is coming up because of the first error. Worth mentioning point is when I type in declare directly works fine. declare | grep USER shows USER=ashfame USERNAME=ashfame values="$SVN_BASH_USERNAME"; So, whats wrong here?

• In NetworkManager, my nm-dispatcher is never called.

  - by Alain Pannetier

  I've got two Ubuntu laptops (both 10.10). One is a new Maverick install and the other has been upgraded many times since 9.04.

How can I Have a look at the source (I looked into the git repo but could not find anything. find why the nm-dispatcher never gets called.

• Programming knowledge vs. programming logic

  - by Shirish11

  Is there any difference between the two topics? I have seen companies asking for Good Programming knowledge some Good Programming logic. I believe that Programming knowledge is related to knowledge about the language in consideration and Programming logic is problem solving logic using programming (in general). Please correct me if I am wrong. Also what is more important. Edit: Do selection of components for application, designing interfaces validating user inputs fall under programming knowledge or Programming logic? Does programming logic simply imply problem solving, or is there anything else which it should comprise of?

• Can you be a web and desktop developer at the same time?

  - by Charmop

  In my environment, I found web programmers, desktop programmers and both web and desktop programmers. About myself I started my career with desktop development using C and then Java, did couple of simple level projects. Then at the final graduating year, my project was a web one, so I turned to web development until this moment. But, when I meet people having chosen to be web or software developers from the beginning, I figure out that they have more knowledge/experience than I have. So I get kind of regret why didn't I specialize my self from the first day? The question is: Is it a good habit to work at two, more or less, different fields: web and desktop? Or we must specialize ourselves?

• How to update a game off a database

  - by James Clifton

  I am currently writing a sports strategy management game (cricket) in PHP, with a MYSQL database, and I have come across one stumbling block - how do I update games where neither player is online? Cricket is a game played between two players, and when they (or one of them) is online then everything is fine; but what if neither player is online? This occurs when championship games are played, and these games need to happen at certain times for game reasons. At the moment I have a private web page that updates every 5 seconds, and each time it loads all games are updated; but then I have the problem that when my private web page stops (for example my computer crashes or my web browser plays up) the game stops updating! Any suggestions?

• ING: Scaling Role Management and Access Certification to Thousands of Applications

  - by Tanu Sood

  Organizations deal with employee and user access certifications in different ways.  There’s collation of multiple spreadsheets, an intense two-week exercise by managers or use of access certification tools to do so across a handful of applications. But for most organizations compliance is about certifying user access for thousands of employees across hundreds of systems. Managing and auditing millions of entitlement combinations on a periodic basis poses a huge scale challenge. ING solved the compliance scale challenge using an Identity Platform approach. Join the live webcast featuring ING’s enterprise architect, Mark Robison, as he discusses how a platform approach offers value that is greater than the sum of its parts and enables ING to successfully meet their security and compliance goals. Mark will also share his implementation experiences and discuss the key requirements to manage the complexity and scale of access certification efforts at ING. Mark will be joined by Neil Gandhi, Principal Product Manager for Oracle Identity Analytics.

• Best way to prevent Google from indexing a directory [duplicate]

  - by Gkhan14

  This question already has an answer here: Stopping Google index some web pages I have 5 answers I've researched many methods on how to prevent Google/other search engines from crawling a specific directory. The two most popular ones I've seen are: Adding it into the robots.txt file: Disallow: /directory/ Adding a meta tag: <meta name="robots" content="noindex, nofollow"> Which method would work the best? I want this directory to remain "invisible" from search engines so it does not affect any of my site's ranking. In other words, I want this directory to be neutral/invisible and "just there." I don't want it to affect any ranking. Which method would be the best to achieve this?

  - by Alberto

  Good morning, I'm very new to Ubuntu. I decided to change to Ububtu (12.10) for my old laptop (Compaq Presario R3000 with AMD Athlon XP 2800+) that previously used Windows XP. After the installation, the PC restarted but, after a certain activity of the HDD stopped. Menwhile, no information from the screen (blank). Then I retried in recovery mode and the activity stopped at a certain point.

• What tools to use for efficient link building?

  - by Evgeny

  As most SEO experts keep saying, it is not just the content that you have - but also a hefty amount of quality incoming links to your content that is important -- these are the two ways to get to the top of the search results. The question is where do I find the incomnig links? One way I know is Google Blog Search, it can be used to find blogs with related information to your content and some allow to leave comments. The comments usually consist of your name, e-mail and website. If you put your keyword instead of your name, then the keyword turns into a link to your website. Unfortunately most blogs put rel=nofollow on such links, but some blogs don't do that. What other ways are there to find quality pages to put keywords links back to your website? Quality link usually means: located on a page with relevant content does not have a rel=nofollow in the <a has a relevant keyword as in <a href=websitekeyword</a the page with the link has high PageRank (3+) and TrustRank

• Simple vs Complex (but performance efficient) solution - which one to choose and when?

  - by ManojGumber

  I have been programming for a couple of years and have often found myself at a dilemma. There are two solutions - one is simple one i.e. simple approach, easier to understand and maintain. It involves some redundancy, some extra work (extra IO, extra processing) and therefore is not the most optimal solution. but other uses a complex approach,difficult to implement, often involving interaction between lot of modules and is a performance efficient solution. Which solution should I strive for when I do not have hard performance SLA to meet and even the simple solution can meet the performance SLA? I have felt disdain among my fellow developers for simple solution. Is it good practice to come up with most optimal complex solution if your performance SLA can be met by a simple solution?

• Is there a LibreOffice equivalent to microsofts office themes?

  - by Dr. Mike

  I've used MS office for many years now. Especially powerpoint. One of the strengths is that it defines and separates the concepts of template and theme. A theme can be saved and contains fonts, colours, and a set of images that can be reused every time you create a new presentation. This ensures that everyone in your organization uses exactly the same colours and fonts all the time. Now I know that you can download templates for LibreOffice, but I have not seen anything similar to the theme concept. The file extensions used in MS office are the following for the two concepts mentioned: Example Powerpoint template file name: mytemplate.potx Example Powerpoint theme file name: mytheme.thmx Now back to my question: Do these concepts and their separation exist in LibreOffice or OpenOffice? If so, how do I create them?

• Should I use title case in URLs?

  - by Amadiere

  We are currently deciding on a consistent naming convention across a site with multiple web applications. Historically, I've been an advocate of the 'lowercase all the letters!' when creating URLs: http://example.com/mysystem/account/view/1551 However, within the last year or two, specifically since I began using ASP.NET MVC & had more dealings with REST based URLs, I've become a fan of capitalizing the first letter of each section/word within the URL as it makes it easier to read (imho). http://example.com/MySystem/Account/View/1551 We're not in a situation where people need to read or be able to understand the URLs, so that's not a driver per se. The main thing we are after is a consistent approach that is rational and makes sense. Are there any standards that declare it good to do one way or another, or issues that we may run into on (at least realistically modern) setups that would choose a preference over another? What is the general consensus for this debate currently?

• How does an Engine like Source process entities?

  - by Júlio Souza

  [background information] On the Source engine (and it's antecessor, goldsrc, quake's) the game objects are divided on two types, world and entities. The world is the map geometry and the entities are players, particles, sounds, scores, etc (for the Source Engine). Every entity has a think function, which do all the logic for that entity. So, if everything that needs to be processed comes from a base class with the think function, the game engine could store everything on a list and, on every frame, loop through it and call that function. On a first look, this idea is reasonable, but it can take too much resources, if the game has a lot of entities.. [end of background information] So, how does a engine like Source take care (process, update, draw, etc) of the game objects?

• C++ difference between "char *" and "char * = new char[]"

  - by nashmaniac

  So, if I want to declare an array of characters I can go this way char a[2]; char * a ; char * a = new char[2]; Ignoring the first declaration, the other two use pointers. As far as I know the third declaration is stored in heap and is freed using the delete operator . does the second declaration also hold the array in heap ? Does it mean that if something is stored in heap and not freed can be used anywhere in a file like a variable with file linkage ? I tried both third and second declaration in one function and then using the variable in another but it didn't work, why ? Are there any other differences between the second and third declarations ?
