• Google indexing pages very slowly [duplicate]

  - by Clark

  This question already has an answer here: Older post not indexed, new post indexed right away? 1 answer Is there anything I can do to speed up the time it takes to index my pages? It's currently indexing them on it's own time I believe which is every 2 - 3 days and when working in music and media I need to have the latest post fairly quickly. My robots.txt file is. User-agent: * Disallow: /wp-admin/ Disallow: /wp-content/ Disallow: /wp-includes/ sitemap: http://vipes.us/sitemapindex.xml If I am understanding this correctly, I would put this URL into Google http://vipes.us/sitemapindex.xml. But in doing so I still only get some of my pages indexed?

• Wrong download of Ubuntu 13.10 desktop: AMD instead of wanted Intel [duplicate]

  - by L. Williams

  This question already has an answer here: Difference between the i386 download and the amd64? 5 answers My PCs are Intel CPUs e.g. Core2 Quad, 64 bit, no AMD in network, but from ubuntu.com/download site, selecting 13.10 Desktop for 64 bit, it repeatedly only offers *AMD.ISO version, which of course fails to install on my Intel (or Atom) based PCs. Wuzzup, and what URL has a download for the Intel CPU systems? Rem: this is for Saucy 13.10 Desktop 64 OS ISO. TIA.

• How to balance programming projects between feasibility and usefulness

  - by tyjkenn

  I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

• Which is the appropriate content-type meta tag value?

  - by Argoron

  I have a question about the meta tag content-type. When starting to build my site (HTML+PHP+JS), I copied a lot of the meta tags over from elsewhere, and I have, amongst others, the following: <meta http-equiv="content-type" content="application/xhtml+xml; charset=iso-8859-1" /> Now, I've seen that tag is being used a lot with the value "text/html". I've been searching the web but could not find a comprehensive explanation regarding what the difference between both is. The "text/html" intuitively sounds more straightforward to me. Should I change my tag to that, or might the "application/xhtml+xml" be an equivalent solution ? Alternatively, can anyone point me to a resource where the different values for these tags are listed and explained in a clear manner? Thanks in advance

• From Java to Javascript? [duplicate]

  - by theGreenCabbage

  This question already has an answer here: Are there any OO-principles that are practically applicable for Javascript? 2 answers I am primarily a Java programmer. Because of its OO principles and the general paradigm of Java programming, like wrapping things in static variables, and having things return specific types, heavily aids me in "visualizing" a program. Instead of thinking of a big program, I can, instead, focus on smaller organized parts of my eventual program, and add functionality and build up from there. Thus, I have trouble programming in other languages. Or at least, I have not been able to program in the same ability as I do in Java compared to other languages. I know Javascript has OO principles, so I'd like to learn this language in a OO-based like I would program with Java. Is this possible?

• Unit testing multiple conditions in an IF statement

  - by bwalk2895

  I have a chunk of code that looks something like this: function bool PassesBusinessRules() { bool meetsBusinessRules = false; if (PassesBusinessRule1 && PassesBusinessRule2 && PassesBusinessRule3) { meetsBusinessRules= true; } return meetsBusinessRules; } I believe there should be four unit tests for this particular function. Three to test each of the conditions in the if statement and ensure it returns false. And another test that makes sure the function returns true. Question: Should there actually be ten unit tests instead? Nine that checks each of the possible failure paths. IE: False False False False False True False True False And so on for each possible combination. I think that is overkill, but some of the other members on my team do not. The way I look at it is if BusinessRule1 fails then it should always return false, it doesn't matter if it was checked first or last.

• How to handle a Tile Map Scrolling [duplicate]

  - by DGomez

  This question already has an answer here: Implementing a camera / viewport to a 2D game 1 answer i'm making a video game, and i'm having, i think, a concept problem. The game will be a platformer which will use tile maps, so to start i will create a mask matrix indicating the tiles to be loaded, and etc..., so my problem is, how to handle the scrolling? should i create a giant mask matrix indicating in each position of the whole level what is supposed to be loaded, and according to the position of the player, change the section to be drawed?? Is this a correct approach to this situation??

• Need some advice on CLI design, I need to provide simple but powerful command line options

  - by howtechstuffworks

  I am writing a utility that runs on RHEL5 command line. I need my command line options to be simple but powerful. I looked at the various UNIX utilities to get an idea of how simple command line utilities have to be. Do you guys suggest any documents/links that talk about command line etiquette? I am modelling my utility on top of LVM (that's all the info I can give for now). I know it's a software engineering question, but I thought it would be appropriate to post here. Please advise.... PS: I am not asking for details about getopt or command line utility parsers.....

• Should single purpose utility app use a class

  - by jmoreno

  When writing a small utility app, that does just one thing, should that one thing be encapsulated in a seperate class, or just let it be part of whatever class/module is used to start the application? I.e. Main would consist of 2 or three lines calling the constructor and then the DoIt methods, nothing else. Or should Main be the DoIt method, with whatever functions it needs added to the main class? Asking because I want to get some alternative perspective, but couldn't find a similar question. If my google-fu is bad and there's a dup, please close.

• Using Copyrighted Images

  - by TMP

  I was thinking about developing a sidescrolling platformer very similar to an old Mario and Luigi game for NES. To start out I was thinking about taking the images from a site like this: http://www.mariouniverse.com/sprites/nes/smb3 Which clearly states a copyright. I was wondering how far I am allowed to take these images. I figure I'm probably allowed to use it for personal development, but what if I publish the game as an exe file and send it to some friends? I figured a definite no-no would be selling the game with the copyrighted images included. A secondary question would be whether or not I would be allowed to modify them slightly and then call them my own.

• GPG Workflow in 11.04

  - by Ross Bearman

  At work we handle the transfer of small bits of sensitive data with GPG, usually posted on a secure internal website. Until Firefox 4 was released, we used FireGPG for inline decryption; however the IPC libraries that it relied upon were no longer present in FF4, making it unusable and it will no longer install in FF5. Currently I'm manually pasting the GPG blocks into a text file, then using the Nautilus context-menu plugin or the command line to decrypt the contents of the file. When we're handling large amount of these small files throughout the day this starts to become a real chore. I've looked around but can't seem to find much information on useful GPG clients in Ubuntu. A client that allowed me to paste in a GPG block and instantly decrypt it, and also paste in plaintext and easily encrypt it for multiple recipients would be ideal. So my question is does this exist? I can't seem to find anything about this with obvious searches on Google, so hopefully someone here can help, or offer an alternative workflow.

• Asking potential developers to draw UML diagrams during the interview

  - by DotnetDude

  Our interview process currently consists of several coding questions, technical questions and experiences at their current and previous jobs. Coding questions are typically a single method that does something (Think of it as fizzbuzz or reverse a string kind of question) We are planning on introducing an additional step where we give them a business problem and ask them to draw a flowchart, activity, class or a sequence diagram. We feel that our current interview process does not let us evaluate the candidate's thinking at a higher level (which is relevant for architect/senior level positions). To give you some context, we are a mid size software company with around 30 developers in the team. If you have this step in your interview process, how has it improved your interviewing veracity? If not, what else has helped you evaluate the candidates better from a technical perspective.

• How does N create it's tileset?

  - by Darestium

  I am trying to recreate a Multiplayer version of the popular flash game N in java. I have a single question however. Are the tiles for the games draw or are they defined with mathamatical formulars/In code? Since I do see how they would scale up in flash if they were not. So if anyone has any ideas how I should go about creating the tileset, or how they are created in the game please let me know. You can check out the game here.

• DNSCrypt-Proxy specific usage

  - by trekkiejonny

  I have some specific usage questions about DNSCrypt-Proxy. I followed a guide and ended with the command dnscrypt-proxy --daemonize –user=dnscrypt Without any further switches does it default to using OpenDNS's resolver server? I want to use specific servers, I found reference to pointing it to the full path of a CSV file. What is the CSV format for use with DNSCrypt? Would it be "address:port,public key"? Does it go in order of working addresses? For example, first resolver doesn't connect it moves on to the second line of the CSV, then third etc. Lastly, would this question be more appropriate in another StackExchange section?

• BIOS Always Freezes Instantly

  - by Louis

  I'm not sure if this is necessarily a Ubuntu question, but I've only had the problem since I installed 12.10. When I turn my computer on, the BIOS screen comes up as usual and... nothing else. When I press any key, I hear a loud beep and there's no response. I've tried looking for similar problems, but in most cases people are at least able to interact with their BIOS even if their OS doesn't load. It seems as though it's just completely freezing as soon as I turn it on.

• How do operating systems… run… without having an OS to run in?

  - by Plazmotech Binary

  I'm really curious right now. I'm a Python programmer, and this question just boggled me: You write an OS. How do you run it? It has to be run somehow, and that way is within another OS? How can an application run without being in an OS? How do you tell the computer to run, say, C, and execute these commands to the screen, if it doesn't have an OS to run in? Does it have to do with a UNIX kernel? If so, what is a Unix kernel, or a kernel in general? I'm sure OSes are more complicated than that, but how does it work?

• Which specific programming activities do women, on average, perform better than men? [closed]

  - by blueberryfields

  Following a recent discussion with female associates in hiring positions for software development/engineering positions, I found out that this kind of information would be incredibly useful to helping make sure that the workforce shows a gender balance. So I went looking. I've found various literature speaking about risk-taking behaviour and patterns, and other statistical differences between men and women when it comes to work performance. See for example this article related to hedge fund management. I have yet to see any such comparison in the computing field. To restate the question: Which specific programming activities do women, on average, perform better than men? Please back up your answers with specific details, preferably by linking to relevant research or, failing that, explaining what you're basing the information on.

• Accepting a numerical range in a function call

  - by dekpos

  I have encountered two ways of doing it: void foo(int from, int to); /* 'from' inclusive, 'to' exclusive */ void foo(int startIndex, int rangelength); Has one style historically been preferred over the other? If so, was it just a matter of convention or was it due to some deeper underlying reason? I'm currently programming in Java and noticed that the Arrays class uses the former style. The exclusivity of the to argument felt somewhat unintuitive to me, which led me to ask this question.

• Installed Ubuntu 14.04. How do I get it working with my new AMD R9 280X. When I run it I get garbage on the display

  - by user289455

  I installed Ubuntu 14.04 on my Gigabyte A88X FM2+ motherboard and A10 7700K processor. Everything worked perfectly. This system is dual booted with Windows 8.1 for gaming and I installed subsequently I installed an AMD r9 280X gpu. Windows was easy. It kept working with the new card installed and I just needed to download and instal the driver. Reboot and it's done. Ubuntu boots into a blank display. I enter the password and can log in. The menu on the left and bar at the top are visible but when I try to open an app, I get blocks and rubbish on the display. My preference is not to remove the card. So, my question is: What would be the procedure I could follow where I can log in using a text based terminal and download and install the AMD drivers.

• Experience embedding javascript

  - by deft_code

  I'm looking into scripting languages to embed in my game. I've always assumed Lua was the best choice, but I've read some recent news about embedding V8 as was considering using it instead. My question is two fold: Does anyone with experience embedding v8 (or another javascript engine) recommend it? How does it compare with embedding Lua? I like that v8 has a c++ embedding API. However Lua API has had lots of time to be refined (newer isn't always better and all that). Note: At this point I'm not too concerned with which is better language or which library has better performance. I'm only asking about ease of embedding.

• Blender 2.6: How to Merge the Pros of Meshes and Surfaces

  - by fridojet

  there are two interesting kinds of objects: Meshes and Surfaces. Each of them offers very cool features. Object Type Specific Features Nice Features of Surfaces: (for example) They're as scalable as vector graphics (really nice!) You can build winding things real simply. Nice Features of Meshes: (for example) You can build organic things really good using the Sculpt Mode and a graphic tablet. You can use some special things like Physics. My Question There are things for which Surfaces are better and things for which Meshes are better. But how can I use both the best features of Surfaces and the best features of Meshes on one object at once? For example: How can I use Physics (like on Meshes) on lossless scalable objects (like Surfaces)? Thanks.

• What do you miss when you have to use C instead of C++?

  - by sharkin

  This is not a question about which of the two languages is better than the other. I myself can't really decide. Pros and cons as always I guess. Also, if you feel you always would prefer C over C++, this poll is not for you :-). However, when I work in C projects I usually feel I'm missing a few language constructs more than others, which can be found in C++. For example, I usually miss (the obvious) classes, but seldomly templates (I always miss STL, but wouldn't call it a language construct). What do you miss when you have to use C instead of C++?

• Does CSS Positioning Affect SEO [duplicate]

  - by etangins

  This question is an exact duplicate of: Make Offscreen Sliding Content Without Hurting SEO [duplicate] If I positioned the very first content that appears in my code below the fold, would that content be given less weight and therefore be less effective with SEO? In addition, if I had a large image that took up most of the top of the screen and resulting in my content being below the fold or toward the bottom of the screen, would that content be given less weight? Note This is content that occurs early on in my code. I'm not talking about having a ton of content and if the content that occurs later would be given less weight, but if content that occurs early on put ends up below the fold would be given less weight.

• Does language endorsement by different platforms (Android, iOS) hurt app development?

  - by MSe

  Developing iOS or OSX based applications typically requires knowledge of Objective C, since XCode is highly tailored to this language. Android, on the other hand, has chosen Java as it's preferred language for app development. Now, I know other programming languages can be used to develop applications on either platform, but lets be honest, it's a lot easier (and encouraged) to develop apps using these "native languages." As a new app developer, it seems like it would be much easier if there was a common language and development environment for developing applications on all the major platforms. This thought is probably too idealistic for a programming discussion, and I wouldn't be surprised if the SE vultures flew in to close this topic. But, here's my question. Do you think that language endorsement creates unreasonable barriers to entry for new programmers, or do you think it's beneficial in some way (if so, why) for these platforms to use completely different development environments and languages for app development?
