• If C-Panel Indexing Manager sets a folder to "No Indexing" can it be crawled by a webcrawler?

  - by Graham

  People are able to view directories / folders on my site right now. So, they could go to mysite.com/images and see the full index. To prevent this, C-Panel offers an option to set a directory / folder to "No Indexing" under the "Index Manager." Will this option allow webcrawlers to crawl / index the images? Or, is there a simpler alternative to block access to all folders directly while still having it SEO friendly? My old server restricted direct access to folders by default. But, the new one does not. Any ideas on this? Thanks!

• 2d engine with WebGL

  - by Philipp

  I am currently developing a HTML5 canvas game with a sprite-based 2d engine. The engine is working well so far, but now I thought that I could maybe add some cool graphic effects when I would re-implement the whole engine with WebGL. The whole graphic engine would stay strictly two-dimensional (think of it as a 3d world where the z coordinate of all vertices is 0.0). What I hope to gain from this is the ability to use pixel shaders to create special effects. I also think that the performance could improve. What do you think about that plan?

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Charakter coding / programming

  - by Jery

  lately I tryed a few times to create charakters for some games, but at some certain point (especially when collision detection came in) everything became messy and the interaction between chars, the world and certain items had a lot of bugs. So here is my question, how do you ussualy keep track of actions that your charakter is allowed to do, or more in general do you have some links / advices how to set up a char efficiantly? I´m working on a char right now, who should at least be able to run, jump, pick items up and use different fighting animations. Most ideas I came up with until now use some kind of action.priority / action.duration system to determain whats possible and what not, or a "action-manager" which defines for every action what is possible from that action on but it all doesnt work that well together =\ thx in advance for some input

• bash script ask for root password

  - by VinceBrowning

  I want have a script that I can give to friends which will add repositories and download files, install them without having to use command as they are not command line savey and have no desire to learn. I need to know how to get the script to prompt them for the root password to allow them to do some of these functions. How would I go about this? Please don't hate on them.. Getting them to start using Linux was a big step and I am just happy that they are attempting something new... and it was in the open source world..

• How can I refactor my code to use fewer singletons?

  - by fish

  I started a component based, networked game (so far only working on the server). I know why singletons can be bad, but I can't think of another way to implement the same thing. So far I have: A GameState singleton (for managing the global state of the game, i.e. pre-game, running, exiting). A World singleton, which is the root entity for my entity graph An EntityFactory A ComponentFactory I'm thinking about adding a "MessageDispatcher" so individual components can subscribe to network messages. The factories do not have state, so I suppose they aren't so bad. However, the others do have global state, which is asking for trouble. How can I refactor my code so it uses fewer singletons?

• Le Web bientôt doté d'un nouveau langage ? CAS s'inspire du CSS pour proposer une définition des attributs des balises HTML dans une feuille

  Le Web bientôt doté d'un nouveau langage ? CAS s'inspire du CSS pour proposer une définition des attributs des balises HTML dans une feuille Tab Atkins Jr, un représentant de Google au sein du W3C (World Wide Web Consortium) vient de proposer à l'organisme un nouveau langage de script pour normalisation. Le langage CAS pour Cascading Attribute Sheets s'inspire grandement du CSS (Cascading Style Sheets), à la différence qu'il est basé sur un concept d'attributs HTML. L'idée de base autour de ce nouveau langage est que tout comme avec le CSS, les développeurs pourront définir dans un fichier des attributs pour les balises HTML, qui seront directement appliqués à l'ensemble ...

• Random List of numbers in C

  - by Ant

  I have just started a C programming course and so far have only done the basics like printf, read a little on variables etc on the course book. The teacher has tasked us with writing a program that will take a value entered by the user, this will be the number of students in the class (25 at the moment but can be variable). It will then list the number of students randomly and place them in 3 columns. The purpose is to sort students into groups of 3 randomly, then display on the screen in columns. Now my question is not for the code that defeats the object of me attempting the exercise, but how to structure it. I can see that using an array can be used to display the list, but really after some pointers on how best to approach the problem in blocks, then I can attempt to program each block.

• What makes Java so suitable for writing NoSQL Databases

  - by good_computer

  Looking at this page that aggregates the current NoSQL landscape, one can see that the majority of these projects are written in Java. Databases are complex systems software dealing with the file system, and so C/C++ would be a better choice than Java for this. (that's my thinking which might be flawed) Secondly, databases deal with transferring large amounts of data from disk to RAM -- which they call a working set. The JVM takes non-trivial amount of RAM for it's own purpose -- so it would be more efficient to use a platform that leaves lots of memory for data instead of hogging it for its own operations. The major relational databases are ALL written in C/C++ MySQL C, C++ Oracle Assembler, C, C++ SQL Server C++ PostgreSQL C SQLite C So what makes Java so popular in NoSQL world.

• Are there any actual examples of profitable programmer's "worker's cooperatives"?

  - by Wannabe Tycoon

  http://en.wikipedia.org/wiki/Worker_cooperative I'm curious whether there are, anywhere in the world, worker's cooperatives that center on a technology business that involves either programming, IT, or some sort of IT or programming related consulting or services. The wikipedia link above is an overview of the concept. The short form explanation is that a co-op is a worker-owned business. Also there is the notion that every worker owns shares in the business. I am interested in knowing whether an example of a "programmer's/IT co-op" even exists. Note: I am not talking about nor asking about a government-funded incubator nor any other socialized, state supported group. I also don't mean "co-working", which is renting an office with other self employed people doing their own thing. I mean a going, profitable IT business operating in a competitive environment that is worker-owned and run.

• Adopt a Java EE 7 JSR!

  - by reza_rahman

  Broad community participation is key to the success of any technology worth it's salt. The Adopt-a-JSR program was launched in recognition of this fact. It is an initiative by some key JUG leaders around the World to encourage JUG members to get involved in a JSR and to evangelize that JSR to their JUG and the wider Java community, in order to increase grass roots participation. There are a number of JUGs that have already jumped in like the Chennai JUG, SouJava, London Java Community, BeJUG, GoJava, Morrocco JUG, Campinas JUG and ItpJava. Note that any developer can participate, there isn't a need to be a JUG leader. There are a number of Java EE 7 JSRs that could use your help right now including WebSocket, JSON, Caching, Concurrency for EE, JAX-RS2 and JMS2. Find out more here.

• I've got two technical degrees but little in the way of experience. How do I get into programming? [closed]

  - by Neonfirelights

  I'm looking for a job, I want to break into programming. I'm looking for the right sort of role and the right place to look for it; I would really appreciate input from someone with industry experience. I've got an excellent academic record: BSc Physics (2:1), MSc Computer Graphics, Vision and Imaging (expecting Merit) from two world ranking universities. I have advanced technical knowledge of C/C++ and Matlab and experience working with C# and VB.NET. Unfortunately I don't have much in the way of commercial experience; unlike a lot of people I know my under-graduate didn't come with a sandwich placement. Where can I go to break into the software industry?

• Touchpad stop working

  - by Diegov

  I'm in a HP 430 PC-Notebook using Oneiric. And sometimes my touchpad just stop working :(... I haven't installed anything, just safe playing with terminal following linuxcommand.org BTW my touchpad has a "hole" that in Windows, it works like this: two touch, block touchpad, two touch, unblock. And as far as I now, Ubuntu hasn't recognize this function so I think that the "hole" is not the problem... Also, I'm pretty sure that I haven't touch a little that... PD: Spanish speaker, sorry if "hole" is not the appropriate term haha.. Thanks!

• How to create a map-like (clouds) texture [duplicate]

  - by user16547

  This question already has an answer here: How do you generate tileable Perlin noise? 9 answers If you place a map of the world on a sphere, it will look like the image is continuous. Basically the left end of the image is sort of a continuation of the right end. You won't be able to see any cuts. I'm trying to create a clouds texture to add to my planet such that it will seem it has clouds. I managed to create the clouds in GIMP, however, I can't figure out how to make sure the left end of my image is a smooth continuation of the right end. For example if you were to map the below image to your sphere (I removed transparency to make it clearer), there would be a very obvious transition from the right end of the image back to the left end on your sphere. How would I create a texture such that I get rid of that? Sorry for my lack of terminology.
