  • how to really master a programming language

    - by cprogcr
    I know that learning a language, you can simply buy a book, follow the examples, and whenever possible try the exercises. But what I'm really looking is how to master the language once you've learned it. Now I know that experience is one major factor, but what about learning the internals of the language, what is the underlying structure, etc. There are articles out there saying read this book, read that book, make this game and that game. But to me this doesn't mean to master a language. I want to be able to read other people's code and understand it, no matter how hard that is. To understand when to use a function and when another, etc etc. The list could go on and on but I believe I've made the point. :) And finally, take whatever language as an example if needed, though best would be if C was taken as an example.

  • Why are 3D game scenarios so big? and.. are them shareable? [closed]

    - by Néstor Sánchez A.
    First, I apologize if this is not the forum for these type of questions. I was wondering... 1- Why 3D games (such as GTA IV) uses so much gigabytes of space? And my half-answar was... because of their huge 3D scenarios. But wait! are not these scenarios made with vector graphics and textures? then.. why are so big??? 2- If they are so big... would really these companies make a whole new scenario for every new game they develop? that would be very inefficient. Doesn't exist "shareable" scenarios that can be used in different games and expanded to no rebuild a whole one (like "New York" or "Liberty City")???. I mean.. the scenarios is almost the same in terms of vertices, just with improved textures.

  • Does Agile (scrum) require one server environment?

    - by Matt W
    Is it necessary/recommend/best practice/any other positive to use only one server environment to perform all development, unit testing and QA? If so, is it then wise/part of Agile to then have only one staging environment before Live? Considering that this could mean internationally distributed teams of developers and testers in different time zones is this wise? This is something being implemented by our QA manager. The opinion put forward is that doing all the dev and testing on a single server is "Agile." The staging environment would be a second environment, and then live.

  • Affect on speed of wordpress membership plugins -- currently trying s2member [migrated]

    - by Richard
    I'm taking a look at s2member -- I have it running, and my site is very slow -- it's taking on average about 9 or 10 seconds to load. This is the site: http://richardclunan.net I want to figure out if the s2member plugin is causing it to be slow. And whether there are other faster membership plugins... 3 questions: Are there particular settings or things specific to s2member that I should take care of to ensure s2member doesn't make my site slow? If I deactivate the plugin to test the speed of the site with the plugin deactivated, will that mean I'll have to respecify s2member settings when I reactivate it? After it's reactivated will members' accounts work ok? Anybody have observations on s2member or other wordpress membership site plugins and their affect on site speed?

  • What web hosts support multi-domain SSL?

    - by Bryan Hadaway
    For Consideration - Please do not close or refer this question to: How to find web hosting that meets my requirements? The above link does not refer to SSL certificates in any manner. This question has a very specific objective of listing known web hosts that support this new SSL technology. If I'm not mistaken, multi-domain (not wildcard) SSL is a relatively new technology that is not hugely supported or well-known/advertised yet? I'm having a difficult time discovering which web hosts support the technology (again because it's not popular enough yet to advertise on feature lists). Here is what I've discovered so far: Web Hosts That DO NOT Support Multi-domain SSL BlueHost/HostMonster DreamHost Web Hosts That DO Support Multi-domain SSL FireHost HostGator Please note that SUPPORT doesn't necessarily mean they offer the SSL certs themselves and you may need to purchase separately.

  • Programming *into* a language vs. writing C code in Ruby

    - by bastibe
    Code Complete states that you should aways code into a language as opposed to code in it. By that, they mean Don't limit your programming thinking only to the concepts that are supported automatically by your language. The best programmers think of what they want to do, and then they assess how to accomplish their objectives with the programming tools at their disposal. (chapter 34.4) Doesn't this lead to using one style of programming in every language out there, regardless of the particular strengths and weaknesses of the language at hand? Or, to put the question in a more answerable format: Would you propose that one should try to encode one's problem as neatly as possible with the particulars of one's language, or should you rather search the most elegant solution overall, even if that means that you need to implement possibly awkward constructs that do not exist natively in one's language?

  • Scrolling Box2D DebugDraw

    - by onedayitwillmake
    I'm developing a game using Box2D (javascript implementation - Box2DWeb), and I would like to know how I can pan the debug draw. I know the usual answer is - don't use debug draw, it's just for debugging. I'm not, however not all my objects are on the same screen, and i'd like to see where they are in the physics representation. How can I pan the debug drawing? As you can see the debug draw stuff, is show on the top left, but it only shows a small part of the world. Here is an example of what I mean: http://onedayitwillmake.com/ChuClone/ The game is open source, If you'd like to poke through and note something that perhaps i'm doing something that is obviously wrong: https://github.com/onedayitwillmake/ChuClone

  • Is MUMPS alive?

    - by ern0
    At my first workplace we were using Digital Standard MUMPS on a PDP 11-clone (TPA 440), then we've switched to Micronetics Standard MUMPS running on a Hewlett-Packard machine, HP-UX 9, around early 90's. Is still MUMPS alive? Are there anyone using it? If yes, please write some words about it: are you using it in character mode, does it acts as web server? etc. (I mean Caché, too.) If you've been used it, what was your feelings about it? Did you liked it?

  • Why do I have to reconnect my usb router cable?

    - by Searock
    I have a Iball Baton ADSD2+ Router. It's working fine but the problem is when I boot into Ubuntu I have to unplug the usb cable and then plug it again, then it starts working. Why do I have to re connect my usb cable? Let me know if you need more details. Edit : I am using a direct connection. I mean to say I don't have to enter a username or password. I am connected to internet as soon as I start my router. The problem is if I start my router before my computer I have to re connect my usb cable. Thanks.

  • Useful git commit messages for merged branches

    - by eykanal
    As a follow-up to this question: If I'm working on a team by myself, I can maintain useful commit messages when merging branches by squashing all the commits to a single diff and then merging that diff. That way I can easily see what changes were introduced in the branch, and I have a single summary describing the feature/change/whatever that was accomplished in that branch when browsing the master branch. My question now is, how can I accomplish this when working with a team? In that situation, the branches will be pushed to a remote repository, meaning that I can't squash all the commits in the branch down to a single commit. If the branch is public, can I still have a single useful merge commit in the master branch? (By "useful" I mean that the commit in the master line tells me (1) a useful summary of what was done in the branch and (2) diffs of the same.)

  • How do you assign commands to keys in Terminal?

    - by NES
    Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.

  • Developing a computer system based on Nand2Tetris [on hold]

    - by Ryan
    I recently finished a book called Nand2Tetris (nand2tetris.org) where I built my own computer system from scratch with its own machine language, assembly code, and a high level language called Jack that's translated to Hack binary. However, I feel like the "computer" I built throughout the course of this book (called the Hack computer) is a bit too simple for various reasons: 1) There are only two registers (D and A), whereas most computers have much more 2) Peripheral devices like mouse and keyboard have to be directly implemented 3) Peripheral devices use a pre-planned shared memory map to communicate with the CPU instead of using interrupts (which aren't covered at all) 4) Jack (the high level language) code doesn't compile to Assembly code directly, instead it compiles to an intermediate language, which in turn gets translated to Assembly. 5) There is no ROM or permanent storage device, everything is stored in RAM 6) No support for colored monitor, networking or sound I would like to build a more complicated computer system now based on what I've learned from Nand2Tetris. Does anyone know of any good resources or books to get started on this? (BTW by computer system I mean software that can emulate the hardware of a virtual computer with its own unique instruction set)

  • Can coding style cause or influence memory fragmentation?

    - by Robert Dailey
    As the title states, I'd like to know if coding style can cause or influence memory fragmentation in a native application, specifically one written using C++. If it does, I'd like to know how. An example of what I mean by coding style is using std::string to represent strings (even static strings) and perform operations on them instead of using the C Library (such as strcmp, strlen, and so on) which can work both on dynamic strings and static strings (the latter point is beneficial since it does not require an additional allocation to access string functions, which is not the case with std::string). A "forward-looking" attitude I have with C++ is to not use the CRT, since to do so would, in a way, be a step backwards. However, such a style results in more dynamic allocations, and especially for a long living application like a server, this causes some speculation that memory fragmentation might become a problem.

  • SSIS 2008 Configuration Settings Handling Logic for Variables Visualized

    - by Compudicted
    There are many articles discussing the specifics of how the configuration settings are applied including the differences between SSIS 2005 and 2008 version implementations, however this topic keeps resurfacing on MSDN’s SSIS Forum. I thought it could be useful to cover the logic aspect visually. Below is a diagram explaining the basic flow of a variable setting for a case when no parent package is involved.   As you can see the run time stage ignores any command line flags for variables already set in the config file, I realize this is not stressed enough in many publications. Besides, another interesting fact is that the command line dtexec tool is case sensitive for the portion following the package keyword, I mean if you specify your flag to set a new value for a variable like dtexec /f Package.dtsx -set \package.variables[varPkgMyDate].value;02/01/2011 (notice the lover case v in .value) You will get errors. By capitalizing the keyword the package runs successfully.

  • Does the lense for videos search youtube correctly

    - by Luis Alvarado
    When I search in youtube.com for "Erika Tipo 11" I get videos about the actual show. When I do the same using the Dash video Lense I get anything else except the actual show. I mean I even get chinesse stuff, some yoga lessons and anything VERY out there that is not even remotely related to the show. Now my questions are: Does the video lense search in a similar way as searching in youtube/vimeo/any other video site? Is there an option apart from the Filter settings to configure the behavior of the search so it searches in a similar way as one would do when searching from the actual site.

  • Usefulness of the Backlinks shown in Webmaster Tools

    - by Ewan Heming
    Is the list of links for a site shown in Google Webmaster Tools a complete list or just a sample? I've noticed that the links in there appear to be all the ones I didn't think would have any real value - either because they were nofollow or from irrelivant sites. The few I did think would be some use have never shown up and there's also some links that are sometimes there and sometimes not (such as my linkedIn profile). Does this mean that the missing links don't/no longer carry any value? It almost appears that the list is there for Google to either inform you about problems (there was a useful list there when someone tried to SPAM my site) or mis-imform you about which link-building strategies work or not (to keep people guessing about what works or not).

  • How do I run Conkeror in Emacs?

    - by Anake
    I have been using emacs for about 3 months, and have been amazed by how much improved my interactions with my computer are. I now use eshell rather than a separate terminal, and the last thing I still need to leave my emacs environment for is for my web browser. I have been reading up on Conkeror, and it seems almost ideal (emacs keybindings, no need to use the mouse etc.) but it runs in a separate window. If it could be run within emacs, it would mean that I would never really have to have interaction with the actual OS, which would be good for someone who is forced to rotate between linux, mac and windows (i.e. me). I understand that it couldn't be run from emacs in -nw mode, but would it be possible (or likely) that Conkeror could be setup to run within an emacs window? Note: - I've tried w3m and didn't really like it

  • Google Dart vs CoffeeScript? Which one should one learn?

    - by garbage collection
    I was thinking about learning CoffeeScript some time in the future. In the mean time, Google came out with Dart that seems to do what CoffeeScript does. Google says: Dart code can be executed in two different ways: either on a native virtual machine or on top of a JavaScript engine by using a compiler that translates Dart code to JavaScript. This means you can write a web application in Dart and have it compiled and run on any modern browser. Does anyone know advantages and disadvantages of learning Dart or CoffeeScript?

  • Proper password handling for login

    - by piers
    I have read a lot about PHP login security recently, but many questions on Stack Overflow regarding security are outdated. I understand bcrypt is one of the best ways of hashing passwords today. However, for my site, I believe sha512 will do very well, at least to begin with. (I mean bcrypt is for bigger sites, sites that require high security, right?) I´m also wonder about salting. Is it necessary for every password to have its own unique salt? Should I have one field for the salt and one for the password in my database table? What would be a decent salt today? Should I join the username together with the password and add a random word/letter/special character combination to it? Thanks for your help!

  • Efficient way to check for changes to the contents of folders

    - by MrVimes
    I am creating an application that maintains a database of files of a certain type in a given folder (and all subfolders) Initially the program will recurse the folders and add any file it finds of that type to the database. I want the application to have the ability to re-scan the folder and add any files that were not there the last time the folders were scanned. It can't use the date created property of the file because there is a high chance of a file being added to the folders that isn't a new file. I am wondering what the most efficient way of doing this is, and if there is a way that doesn't involve checking each file is in the database already (which, if there are 5000 files would mean 5000 queries of a list 5000 items in size, or 25 million 'checks' for the sql engine to perform) I suppose a more specific question to acheive the same goal would be - is there a property of a file (in Microsoft Windows) that will reliably tell you when that file arrived in that folder.

  • Software/Application needed to store and organize random content [on hold]

    - by Rami.Shareef
    I have the need to store random contents (on my local hard drive/ laptop hard drive) for personal use so I can look these contents up later on when I need them. What I mean by random content is one of the following: Some sort of code Random fact Css / html / Javascript tips Or anything I might find interesting and want to keep for future reference I want to look up these entries by tags, the software should give me the ability to associate every entry with one tag or more. I have been having difficult time find applications offer this functionality, it is like a local database with search ability and easy data-entry methods. I can build one, but I don't have the time to invest in doing so. Can you refer me to any application/software that can do that, it would be great. It does not matter if it is paid or free.

  • Ubuntu One not syncing and not providing feedback

    - by Joe
    Firstly, I apologize for not being more specific with my problem, but Ubuntu One is just not providing me with any information. It appears to be working, it states that "syncronization in progress..." but it never actually syncronizes (by never I mean 3 days). When I first selected a folder to sync using Ubuntu One it took on the order of hours to sync over 500MB of files - it uploaded the folder hierarchy first and populated the folders over a few hours. That is not happening at all now. Please let me know if there is a way I can get more information out of Ubuntu One that I can post and hopefully resolve this issue. Thanks, Joe

  • Why is 2^16 a "special" number?

    - by javamonkey79
    OK, I feel stupid asking this - but in Jeff's article: Getting the Interview Phone Screen Right and originally stated in the 5 essential phone screen questions: They shouldn't stare blankly at you when you ask with 2^16 is. It's a special number. They should know it. I've been a developer\software engineer\code monkey\whatever for a little while now, and I don't think I've ever come across this. I mean, I can certainly count binary values do basic operations on them, etc, etc. But I don't see what is "special" about this value.

  • SUN Java and GPL V2 licence issue for linked applications

    - by user255607
    I have recently noticed that the Sun Java code has been released as GPL V2 code (see Google code repo). Does that mean that all applications written in Java and linked to Sun APIs (beans, and so on) are also in GPL ? If we strictly follow the GPL then this should be the case (Libs should be in LGPL, not GPL if we want to build proprietary software on top of it). Is there another commercial licence which can avoid such an issue ? I cannot believe this is the case. There must be an explanation on this. Regards, Apple92
