  • PHP speed optimisation.

    - by Petah
    Hi, Im wondering about speed optimization in PHP. I have a series of files that are requested every page load. On average there are 20 files. Each file must be read an parsed if they have changed. And this is excluding that standard files required for a web page (HTML, CSS, images, etc). EG - client requests page - server outputs html, css, images - server outputs dynamic content (20+/- files combined and minified). What would be the best way to serve these files as fast as possible?

  • The right way to start out in game development/design [closed]

    - by Marco Sacristão
    Greetings everyone I'm a 19 year old student looking for some help in the field of game development. This question may or may not seem a bit overused, but the fact is that game development has been my life long dream, and after several hours of search I've realized that I've been going in circles for the past three or four months whilst doing such research on how to really get down and dirty with game development, therefor I decided to ask you guys if you could help me out at all. Let me start off with some information about me and things i've already learned about GameDev which might help you out on helping me out (wordplay!): I'm not an expert programmer, but I do have knowledge on how to program in several languages including C and Java (Currently learning Java in my degree in Computer Engineering), but my methodology might not be most correct in terms of syntax (hence my difficulty in starting out, i'm afraid that the starting point might not be the most correct, and it would deploy a wrongful development methodology that would be to corrected later on, in terms of game development or other projects). I have yet to work in a project as large as a game, never in my learning curve of programming I've done a project to the scale of a video game, only very small software (PHP Front-ends and Back-ends, with some basic JQuery and CSS knowledge). I'm not the biggest mathematician or physicist, but I already know that is not a problem, because there are several game engines already available for use and integration with home-made projects (Box2D, etc). I've also learned about some libraries that could be included in said projects, to ease out some process in game development, like SDL for example. I do not know how sprites, states, particles or any specific game-related techniques work. With that being said, you can see that I have some ideas on game development, but I have absolutely no clue on how to design and produce a game, or even how game-like mechanics work. It does not have to be a complex game just to start out, I'd rather learn the basic of game design (Like 2D drawing, tiling, object collision) and test that out in a language that I feel comfortable in which could be later on migrated to other platforms, as long that what I've learned is the correct way to do things, and not just something that I've learned from some guy on Youtube by replicating that code on the video. I'm sorry if my question is not in the best format possible, but I've got so many questions on my mind that are still un-answered that I don't know were to start! Thank you for reading.

  • What is a good software development plan?

    - by Totophil
    Whilst browsing through answers on SO I came across something that is, in my view, one of the more frequent software development management misconceptions: "[software development] plan is a reasonably detailed description of all the activities you need to undertake". Hence the question: what is good software development plan? Can it be boiled down just to a work breakdown structure; is WBS the single most important thing for a software development plan anyway?

  • Why isn't Java more widely used for game development?

    - by Anto
    I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

  • What quality standards to consider for software development process?

    - by Ron-Damon
    Hi, i'm looking for metrics/standards/normatives to evaluate a given "Software Development Process". I'm NOT looking to evaluate the SOFTWARE itself (trough SQUARE and such), i'm trying to evaluate software development PROCESS. So, my question is if you could give me some pointers to find this standard, considering that "evaluation objetives" would be documentation quality, how good is the customer relation, how efective is the process, etc. Very much like a ISO 9000, and like CMMI on a sense, but much lightweight and concrete and process oriented, not company oriented. Please help, i'm trying to stablish the advantages of our development process as formal as i can.

  • I would like to know what kind of tools I should be looking for web development.

    - by user646636
    I would like to know what kind of tools I should be looking for web development. I have learned the basics of HTML/CSS/PHP/JS/phpmyadmin Now, I was looking to a write a website for purchasing and selling products for clients and sellers. I was wondering what other languages I would need to learn and also what kinda development tools I should use. Also, what would be the best type of language to write a website like this. I have heard that I should be using python for this type of web development. Do you guys have any suggestion as to what I should be looking at? And Also I would like to know if I should be setting up my own database or should I be using something like MySQL. I'm looking for languages that would have low maintenance cost in the long run. Thanks

  • What's the best way to move to linux from windows for web development ?

    - by rajesh pillai
    I am primarily a programmer developing on windows based OS using c# as my primary language. I am evaluating Ubuntu Linux as an alternate platform and would like to know the best stack for doing web development on this. I had gone through the following thread Moving development from Windows to Linux but it doesn't answer my questions fully. Some of the points I am interested are outlined below PHP/Ruby/Python (What would you recommend?) Is Mono mature enough for any large scale development? Has anyone any real experience using Mono. IDE (including debugging support, intellisense, source control integration,Unit testing) Unit testing framework based on the language recommended Web framework if any. Load Testing tools Web server (I know there are many webservers, but would like to know which one is primarily used by most people) Your inputs is greatly appreciated. Thanks.

  • Why is web app development path in Java this much confusing? [closed]

    - by Farshid
    I'm currently a .net web developer and I really like to switch to Java. I've used JSP about 7 years ago to develop and deploy a small web application on a JRUN app server. But after 7 years that I like to return back to Java, I can't find the clue. There are many web development frameworks that exist in Java world and each of them has fans that recommand it. There are extensions that sit above jvm for web development (like jRuby i think). I am confused and I do not know where to start the path of learning java web development. I do not want to focus on custom tailor-made approaches and want to remain on the basic path of developing with standard tools and methods and deploy them into standard app servers. (For example some says do not use EJBs, some says focus on MVC facilities like JSF. I'm confused and I do not know the path that i should go on)

  • Starting small custom development company, type of niches to target?

    - by Rick
    This is kind of a new years thing for me as I want to be more entrepreneurial going forward with programming and this is kind of a general question for anyone who may share the same ambitions as me. I have experience with web programming and, although I work full time for a company doing programming, I have some freelance programmers that I work with / employ for small projects. I want to see about taking things to the next level as far as building a small company doing custom development. I'm just not sure how to figure out what niches to target as far as what type of apps to build as demos, etc. I was thinking mobile (maybe Android or Iphone) but am just curious if anyone has any advice / resources. A lot of "web development" seems to end up being just using a CMS like Joomla or Wordpress, for smaller sites, so I want to figure a way to steer clear of this crowd and find some opportunity with companies / entrepreneurs who actually need real programming development done to build apps. Thanks for any advice

  • What steps/tools/apps are necessary to make local php development on a tablet viable?

    - by Tchalvak
    I do my php web development locally, as in, creating a local instance of a site and then coding it and then pushing code to servers via git/github. I'm considering getting an android tablet or ipad and a wireless keyboard for very mobile development, but I in no way want to go back to the bad old days of using ftp and syncing up code changes on a development server directly, that would be too much of a trade-off to interest me. Is there enough support for the stack to develop php websites locally on a tablet? Anyone had experience trying this sort of thing?

  • How would I pursue a track in front-end web development?

    - by Koviko
    I've recently been put on heavy JavaScript projects and have become fond of the front-end world in comparison to the back-end. I have always been good at proper markup and CSS, and coupled with AJAX, pretty animations, and dynamically generated content, it's become a much more interesting and flashy world for me. I would like to be able to continue to hone my craft in the same way that I was able to become proficient at back-end development with PHP: getting paid to do it. How would I market myself as a front-end web developer with a strong interest in dynamic JavaScript-driven websites? Due to my strong background in back-end development, how would I find the companies that wouldn't waste my front-end skill set on simple HTML/CSS development? And as a bonus, how would I apply this to being a contractor/freelance developer rather than a salaried employee? While I like the idea of being able to remain a part of my creations, I also dislike the maintenance phase of projects.

  • What should you include in a development approach document?

    - by Liggy
    I'm in the middle of co-producing a "development approach" document for off-shore resources as they ramp up onto our project. The most recent (similar) document our company has used is over 80 pages, and that does not include coding standards/conventions documents. My concern is that this document will not be consumable and will therefore fail. What should be in a development approach document? Are there any decent guidelines on this topic? EDIT: The development approach document should detail the practices and techniques that will be used by software developers while software is designed, built, and tested.

  • Distributed development staff needing a common IP range

    - by bakasan
    I work on a development staff that is geographically distributed, mostly all throughout the state of CA, but several key members also must travel frequently. We rely quite heavily on a 3rd party provider API for a great deal of our subsystems (can't get into who it is or what they do). The 3rd party however is quite stringent on network access and have no notion of a development sandbox. Access is restricted to 2, 3 IP numbers and that's about it. Once we account for our production servers, that leaves us with an IP or two to spare for our dev team--which is still problematic as people's home IP changes, people travel, we have more than 2 devs, etc. Wide IP blocks are not permitted by the 3rd party. Nor will they allow dynamic DNS type services. There is no simple console to swap IPs on the fly either (e.g. if a dev's IP at home changes or they are on the road). As none of us are deep network experts, I'm wondering what our viable options are? Are there such things as 3rd party hosts to VPNs? Generally I think of a VPN as a mechanism to gain access to a home office, but the notion would be a 3rd party VPN that we'd all connect to and we'd register this as an IP origin w/ our 3rd party. We've considered using Amazon EC2 to effectively host a dev environment for each dev and using that to connect. Amazon only gives you so many static IPs however (I believe 5?) so this would only be a stop gap solution until our team size out strips our IP count at Amazon. Those were the only viable thoughts that I had, but again, I'm far from a networking guy. Tried searching for similar threads, but I'm not even sure I know the right vernacular to look around for.

  • Mac compatible Web-Development Tools

    - by Derek Adair
    Hi, I'm looking for any Mac compatibile development tools that are tried and tested. I'm quite sick of my MySQL query browser crashing... And i'm sure there is probably better software out there anyways... At the moment my focus is dedicated to application development using PHP/MySQL/Ajax. (although, I will be learning ActionScript/Flex shortly). Here are the apps I regularly use and a general idea of the environment I work in: Hosting - localhost: Mamp Production: Amazon EC2 IDE - Coda: PHP/Mysql/Javascript Mysql - PHPMyAdmin MySQL query browser FTP - Coda FileZilla X11 is used for connecting to my production environment I am mainly looking for... -tools that will help me better manage (create, edit... whatever) databases. -Version control. This is huge as I'm working with a team of three other developers (we reeeeeeaaally need to standardize our environments..) Although any cool little tools to make my job easier are always a plus! I am unable to insert more than one link as I'm not rated on this forum.

  • What is the best IDE setup for web development?

    - by Yuval A
    I am starting a little side project which consists of building a small-medium sized, django-based, website. However, last time I was actually in the business of websites, was a few good years ago. So while still technologically capable, I'm still rusted on the tools/IDE part of websites. I am looking for an IDE which can support the following: Basic HTML editing with syntax completion, highlighting, etc... Basic CSS editing with syntax completion, highlighting, etc... Python support for Django Support for the entire develop-debug-FTP upload cycle If all of this could happen inside my existing eclipse installation, it would be nothing short of perfection. So what's your recommendation on web development IDEs? EDIT: forgot to add that I'm running Win XP on my dev machine. EDIT after answers: thanks all you guys for the helpful advice. I think I'm going to go with Aptana as it fits in to eclipse which I already use. Also I will look into version control instead of simple FTP upload. Apparently I didn't know how much it is used even in web projects.

  • What is your preferred tool stack for PHP development in the Windows Environment?

    - by Tim Visher
    I have been developing basic web sites for awhile now with some PHP thrown in for getting dynamic stuff done. However, I recently decided that it was time I got my hands a little dirtier so I wanted to start to play with the underpinnings of Wordpress and other such apps. I work on a Mac at home and have been using Coda for most of my editing needs and I love it. Also, to manage the services stack I use MAMP at home. However, I've begun to realize that for heavy PHP and Web work (AJAX, etc.), more is needed. I'm very interested to hear the kinds of tools more experienced web developers use on a day to day basis to manage the entire work flow. I found this article over on developer tutorials and decided to go with XAMPP (for the moment) for managing the services. However, IDE, Source Control, Debugger, etc. are all up for grabs. Anyway, your thoughts are much appreciated. And, if at all possible, try to describe your entire stack with what each tool fulfills for your development process.

  • Tools required for a Web Development Project..

    - by RBA
    Hi, I wanted to design a project in linux which could contain programming languages(C, perl, PHP, HTML, XML etc) basically a web based project. Why i have chosen to build on Linux is because it is Open Source, and lot many things can be automated through scripting languages, which in windows i don't know. So, i have installed linux on a virtual machine(Host-Windows 2007 & Guest Linux CentOS), CentOS(command line interface). Since i am a beginner, so I want to know what all tools can be used to facilitate and ease my development process. Some which i know are listed below, and request you to please share your experience on this. 1) Using Putty so that can access the Linux machine from anywhere within the network. 2) Since i want to develop on Linux, but want to use windows as developing platform. So have downloaded Eclipse Editor (C/PHP) on windows. But want to know how can i access linux files from here?? 3) Installed Samba, and still trying to figure out how can i access linux files remotely on Windows. 4) Please share your experience, as how can i ease my development process. and what all tools i can use..?? Please let me know if you need any other clarification..

  • Increase Query Speed in PostgreSQL

    - by Anthoni Gardner
    Hello, First time posting here, but an avid reader. I am experiancing slow query times on my database (all tested locally thus far) and not sure how to go about it. The database itself has 44 tables and some of them tables have over 1 Million records (mainly the movies, actresses and actors tables). The table is made via JMDB using the flat files on IMDB. Also the SQL query that I am about to show is from that said program (that too experiances very slow search times). I have tried to include as much information as I can, such as the explain plan etc. "QUERY PLAN" "HashAggregate (cost=46492.52..46493.50 rows=98 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Append (cost=39094.17..46491.79 rows=98 width=46)" " - HashAggregate (cost=39094.17..39094.87 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on movies (cost=0.00..39093.65 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Nested Loop (cost=0.00..7395.94 rows=28 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on akatitles (cost=0.00..7159.24 rows=28 width=4)" " Output: akatitles.movieid, akatitles.language, akatitles.title, " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Index Scan using movies_pkey on movies (cost=0.00..8.44 rows=1 width=46)" " Output: public.movies.movieid, public.movies.title, public.movies.year, public.movies.imdbid" " Index Cond: (public.movies.movieid = akatitles.movieid)" SELECT * FROM ((SELECT DISTINCT title, movieid, year FROM movies WHERE title ILIKE '%Babe%' AND NOT (title ILIKE '"%}')) UNION (SELECT movies.title, movies.movieid, movies.year FROM movies INNER JOIN akatitles ON movies.movieid=akatitles.movieid WHERE akatitles.title ILIKE '%Babe%' AND NOT (akatitles.title ILIKE '"%}'))) AS union_tmp2; Returns 612 Rows in 9078ms Database backup (plain text) is 1.61GB It's a really complex query and I am not fully cognizant on it, like I said it was spat out by JMDB. Do you have any suggestions on how I can increase the speed ? Regards Anthoni

  • Detecting Connection Speed / Bandwidth in .net/WCF

    - by Mystagogue
    I'm writing both client and server code using WCF, where I need to know the "perceived" bandwidth of traffic between the client and server. I could use ping statistics to gather this information separately, but I wonder if there is a way to configure the channel stack in WCF so that the same statistics can be gathered simultaneously while performing my web service invocations. This would be particularly useful in cases where ICMP is disabled (e.g. ping won't work). In short, while making my regular business-related web service calls (REST calls to be precise), is there a way to collect connection speed data implicitly? Certainly I could time the web service round trip, compared to the size of data used in the round-trip, to give me an idea of throughput - but I won't know how much of that perceived bandwidth was network related, or simply due to server-processing latency. I could perhaps solve that by having the server send back a time delta, representing server latency, so that the client can compute the actual network traffic time. If a more sophisticated approach is not available, that might be my answer...

  • Improve speed of a JOIN in MySQL

    - by ran2
    Dear all, I know there a similar threads around, but this is really the first time I realize that query speed might affect me - so it´s not that easy for me to really make the transfer from other folks problems. That being said I have using the following query successfully with smaller data, but if I use it on what are mildly large tables (about 120,000 records). I am waiting for hours. INSERT INTO anothertable (id,someint1,someint1,somevarchar1,somevarchar1) SELECT DISTINCT md.id,md.someint1,md.someint1,md.somevarchar1,pd.somevarchar1 from table1 AS md JOIN table2 AS pd ON (md.id = pd.id); Tables 1 and 2 contain about 120,000 records. The query has been running for almost 2 hours right now. Is this normal? Do I just have to wait. I really have no idea, but I am pretty sure that one could do it better since it´s my very first try. I read about indexing, but dont know yet what to index in my case? Thanks for any suggestions - feel free to point my to the very beginners guides ! best matt

  • Multi-platform development from one computer

    - by iama
    I am planning to build a new development computer for both Windows & Linux platforms. On Windows, my development would be primarily in .NET/C#/IIS/MSSQL Server. On Linux—preferably Ubuntu—my development would be in Ruby and Python. I am thinking of buying a laptop with Windows 7 pre-installed with 4GB RAM, Intel Core 2 Duo, and 320 GB HD; running 2 VMs for both Windows and Linux development with the host OS as my work station. Of course, I would be running DBs and web servers on the respective platforms. Is this a typical setup? My only concern is running two VMs side by side. Not sure if this configuration would be optimal. Alternative would be to do my Windows development on the host Windows 7 OS. What are your thoughts?

  • Compare Your Internet Cost and Speed to Global Averages [Infographic]

    - by ETC
    Internet pricing and speed varies wildly across the world. The US, for instance, currently ranks 15th in speed but enjoys reasonably priced internet access. How reasonably priced? If you’re a US citizen you likely have an average internet access speed of 4.8 mbps and you pay a little over $3 per mbps. If you’re in Sweden, however, you likely have an 18 mbps connection and you pay a scant 63 cents per mpbs. The real envy of the internet speed Olympics by far is Japan with a mighty 61 mbps at a mere 27 cents per mbps.
