  • practical use of knowledge vs tutorials [on hold]

    - by Lauris Skraucis
    I DONT NEED FACTS,I NEED OPINIONS FROM OTHER DEVELOPERS! Which would be more useful, spend more time on tutorials than on practical use of knowledge or spend more time making real life apps? Like I do everything 50/50 or better I spend all time practicing and putting my knowledge in real life things (php, jQuery, AngularJS)? This is a big pain, I learnt jQuery, then Angular, then php, but didn't practice and forget the code, now I watched basic and intermediate tutorials to refresh knowledge, so what do you think what is the best?

  • Using GDI+ vs HTML page

    - by Umesha MS
    I am working on an application which is UI intensive (i.e. we need to customize all the control to look different). For this is I planned to use GDI+ in win32. But one of the suggestion form our team member is, Instead of using GDI+ he asked me to have a web browser control, in that he asked me to display local html.That html page contains customized controls. Form his suggestion I created a web control and used some UI intensive local html pages. That looks good. But my question is, is it is a good idea to use web control to solve this?

  • Apache Virtualhosts with PHP and custom logs - how to isolate PHP errors?

    - by Repox
    I'm trying to setup a simple hosting enviroment for my application on an Ubuntu server. I created a virtualhost like this: <VirtualHost *:80> ServerAdmin [email protected] ServerName www.example.com ServerAlias example.com DocumentRoot /home/owner/example.com/docs <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/owner/example.com/docs/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /home/owner/example.com/logs/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /home/owner/example.com/logs/access.log combined php_flag log_errors on php_value error_log /home/owner/example.com/logs/php-error.log </VirtualHost> Now, my problem is that PHP errors and warnings are thrown in the error.log - not the php-error.log as I was hoping. How can achieve this?

  • Websockets VS SSE

    - by user3385828
    Sorry for asking this here, I bet it has been asked plenty of times before but this time it's something specific which I haven't understood anywhere else: Suppose I have a service which requires to seek the database for different data once and in a while. For this I have 2 or 3 SSE, each one with a different retry basetime (20000 miliseconds, 1000 miliseconds...). What I'd like to know is if websockets can handle different "data type" accordingly to the request, for example, could I create one websocket to handle a notification system, a chat system, a group system instead of separated SSEs and treat data differently with javascript? And if so, would it be of higher interest (performance) than actually performing different queries to the server through different SSEs?

  • Multiple parameters vs single parameter(object with multiple properties)

    - by Shwetanka
    I have an Entity Student with following properties - (name, joinedOn, birthday, age, batch, etc.) and a function fetchStudents(<params>). I want to fetch students based on multiple filters. In my method I have two ways to pass filters. Pass all filters as params to the method Make a class StudentCriteria with filters as fields and then pass the object of this class While working in java I always go with the second option but recently I'm working in php and I was advised to go with the first way. I am unable to figure out which way is better in maintaining the code, reusability and performance wise. Thanks.

  • URL Encryption vs. Encoding

    - by hozza
    At the moment non/semi sensitive information is sent from one page to another via GET on our web application. Such as user ID or page number requested etc. Sometimes slightly more sensitive information is passed such as account type, user privileges etc. We currently use base64_encode() and base64_decode() just to de-humanise the information so the end user is not concerned. Is it good practice or common place for a URL GET to be encrypted rather than simply PHP base64_encoded? Perhaps using something like, this: $encrypted = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $string, MCRYPT_MODE_CBC, md5(md5($key)))); $decrypted = rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode($encrypted), MCRYPT_MODE_CBC, md5(md5($key))), "\0"); Is this too much or too power hungry for something as common as the URL GET.

  • C++ Database vs Reading Files

    - by Ohmages
    Ive been programing a C++ game/server for the past year. I have been using MYSQL for character logins, items, monsters, etc, etc. (im on windows). My question is, what are some of the databases that some big time developers use. IE. Battle.net, Diablo II, Diablo III, mythos, hellgate , etc, etc, etc. Do they have their own database they built? Or do they use an existing framework for logins, and character transfers. I do know that in diablo II, they use character files to to transfer characters into the game world. But what about the login into battle.net. Would it be wiser for me to stick with MYSQL, or is there something out there faster and more stable, or should I create a login type of system that looks through a file to see if you provided the correct password. Can't wait to get some replies. Thanks! PS. Currently the framework is much like battle.net, where you login into a lobby, create, and join games. The game server/lobby server are different servers too. So im just wondering about the lobby server for logins because I'm expecting several hundred thousand connections/logins.

  • Falsey values vs null, undefned, or empty string

    - by user687554
    I've worked with jQuery over the years. However, recently, I've found myself getting deeper into the JavaScript language. Recently, I've heard about "truthy" and falsey values. However, I don't fully understand them. Currently, I have some code that looks like this: var fields = options.fields || ['id', 'query']; I need to identify if fields is null, undefined, or has a length of 0. I know the long way is to do: if ((fields === null) || (fields === undefined) || (fields.length === 0)) { ... } My question is, is the following the same: if (!fields) { ... } Thank you!

  • Website project takes a long time to load in VS.NET 2008

    - by rm
    After getting a new computer (a lot faster than the one I've used before) my Solutions take A LONG TIME (3-4 minutes) to load up in VS.NET 2008. I only have 2 projects in the solution: DB Project and Website Project (from IIS). If I remove the Website Project from Solution - it loads up instantly, when I add that same website project to the OPEN Solution - it loads up instantly. The only time it's slow is when I open the solution referencing my Website project. I had the exact same setup (as far as VS is concerned) on my old box, and never had this problem. Any ideas?

  • for vs. foreach vs. LINQ

    - by beccoblu
    When I write code in Visual Studio, ReSharper (God bless it!) often suggests me to change my old-school for loop in the more compact foreach form. And often, when I accept this change, ReSharper goes a step forward, and suggests me to change it again, in a shiny LINQ form. So, I wonder: are there some real advantages, in these improvements? In pretty simple code execution, I cannot see any speed boost (obviously), but I can see the code becoming less and less readable... So I wonder: is it worth it?

  • PHP error log does not display script names nor does it display the errors' line numbers [migrated]

    - by gnxtech3
    I think the title is self-explanatory, and my Google-fu isn't bringing up anything useful. I'm working on a new host, and my php error log only displays the error itself, not which script is the offender, nor which line number the error is occurring on. Makes it a tad difficult to debug, especially since there's only 1 error in the script. More info: I'm not using a custom error handler that I'm aware of. This is a standard Wordpress install. The error was [27-Aug-2012 19:22:36 UTC] PHP NOTICE: Trying to get property of non-object. Just no script name or line number in the error I found that Wordpress' error logging contained the information to debug the problem, but that doesn't explain why the log didn't contain line number or script.

  • How to find where error is.

    - by gurugio
    How can I find where the error occurs? In C language, the return value means what error occurs, such as failure to open file or memory allocation. There is no information where the error occurs. For example, function 'foo' calls A,B,C,D. If foo returns an error value, it might be return value of A or B or C or D. I cannot find what function returns error. I have to run debugger or add some codes to find what function returns error.

  • Working alone vs with others

    - by tmewett5
    Being a student in a small school, there aren't a lot of people (well, there aren't any) that share the same passion or skill of programming that I have. I have been learning to program myself since the age of 9, and I believe I have reached the level where I am ready to do something more ambitious, as opposed to the little scripts and personal web design I do at the moment. The point is: would having a small group - or just another person - allow us to achieve greater things? If so, how would I begin building a team?
