  • Python as your main language. Possible?

    - by Deinumite
    I am currently attending college and the languages that I will 'know' by graduation are C++ and Java. That being said, i am also in the process of teaching myself Python. I know that every programming language has its own pros and cons, but would it be possible to become a python developer out of school? I always have more 'fun' programming in Python than i do in C++ or Java, and I am also in love with Pythons documentation. I know C++ will always be on top in terms of speed, but what would be the benefit of memorizing every javadoc against focusing on Python instead? are there good jobs to be had with Python? edit: also, would it be beneficial for me to look at C# as well? Microsoft is really throwing their support at it so that could be a decent career path as well.

  • What would you recommend for a undergraduate final year project?

    - by Thach Tran
    To narrow down the question, please suggest web-based topics only. To be honest, I'm struggling to find one for myself :) I'm doing Computer Science and looking for a web-based, individual project. A suitable topic would have a certain degree of novelty, so while you guys browsing the web everyday, what kind of things you expect but haven't come up before. Sorry for my lousy English :)

  • JQuery: How to perform a "push" slide, not a slide up?

    - by Tedy
    I using the following JQuery: $("#pushSlideDiv").slideDown("fast"); However, this creates a "slide" effect. Meaning, if I do a slidedown, this makes the underlining DIV reveal it's self from a top-to-bottom reveal. I want a "push" effect, where the slidedown instead reveals as though the div is being pushed onto the page ... where you first see the bottom of the div. How can I do this with JQuery? UPDATE: This isn't a great example, but it does show a push effect that I'm trying to accomplish vs a "slide" effect.

  • Developers: How does BitLocker affect performance?

    - by Chris
    I'm an ASP.NET / C# developer. I use VS2010 all the time. I am thinking of enabling BitLocker on my laptop to protect the contents, but I am concerned about performance degradation. Developers who use IDEs like Visual Studio are working on lots and lots of files at once. More than the usual office worker, I would think. So I was curious if there are other developers out there who develop with BitLocker enabled. How has the performance been? Is it noticeable? If so, is it bad? My laptop is a 2.53GHz Core 2 Duo with 4GB RAM and an Intel X25-M G2 SSD. It's pretty snappy but I want it to stay that way. If I hear some bad stories about BitLocker, I'll keep doing what I am doing now, which is keeping stuff RAR'ed with a password when I am not actively working on it, and then SDeleting it when I am done (but it's such a pain).

  • IE6 Overflow Issue

    - by Nimbuz
    <div style="float:left; width:50%;"> div 1 <div style="position:absolute; width:105%">nested element</div> </div> <div style="float:left; width:50%;"> div 2 </div If an element exceeds the width of its floated parent element, the next element is pushed down unless I apply overflow:hidden on both floated elements, which defeats the purpose because I DO NOT want to hide the overflowing content. Is there any fix for it?

  • different for loops java

    - by Ayrton
    I'm having some difficulties with the following problem: I'm making a little game where you're at a specific spot and each spot has each some possible directions. The available directions are N(ord),E(ast),S,W . I use the function getPosDirections to get the possible directions of that spot. The function returns the directions into an ArrayList<String> e.g. for spot J3: [E,W] Now the game goes like this: 2 dice will be rolled so you get a number between 2 and 12, this number represents the number of steps you can make. What I want is an ArrayList of all the possible routes e.g.: I throw 3 and I'm currently at spot J3: [[E,N,E],[E,N,S],[E,S,E],[E,S,S],[W,N,E],[W,N,S],[W,S,E],[W,S,S]] How would obtain the last mentioned Array(list)?

  • Very Urgent :How to start a new session if a user click on the new tab in IE or mozilla on websphere

    - by ha22109
    Hi, I have one "user search" portlet on the home page of one application running on websphere portal server.Which display the matching user records as per the search criteria filled in the search form.I have requirement to have a "back to search input" link on the results page which onclick should show the filled form on the input jsp. The issue which i am facing is if i open the application in two diff tab of same IE browser and start giving some search criteria and submit and same time search for some other input from other IE tab (in the same browser)and then go back to previous tab and click on "back to search input" link then instead of showing me the first input it will show me the imput which i entered in the next IE tab. I am setting and getting the bean(form bean) through portlet session.but in the two diff tab of same IE it will be the sae user session (and may be the same portlet session..) Please tell me solution for this. The one thing to be notice here is i can access this "user search" application even without doing login also.so it must be taking the default portlet session in this case. what wil happen once i login and then search,will it going to overwrite the portlet session and http session or howz is that?

  • JavaScript: How do I create an Array into another Array?

    - by Timnkd
    I have the following JavaScript Array: var jsonArray = { 'homes' : [ { "home_id":"203", "price":"925", "sqft":"1100", "num_of_beds":"2", "num_of_baths":"2.0", }, { "home_id":"59", "price":"1425", "sqft":"1900", "num_of_beds":"4", "num_of_baths":"2.5", }, // ... (more homes) ... ]} I want to convert this in an Array like such (pseudo code): var newArray = new Array(); newArray.push(home_id's); How can I do that? Notice how the newArray only has home_ids from the big jsonArray array.

  • Error logging/handling on application basis?

    - by Industrial
    Hi everybody, We have a web server that we're about to launch a number of applications on. On the server-level we have managed to work out the error handling with the help of Hyperic to notify the person who is in charge in the event of a database/memcached server is going down. However, we are still in the need of handling those eventual error and log events that happen on application level to improve the applications for our customers, before the customers notices. So, what's then a good solution to do this? Utilizing PHP:s own error log would quickly become cloggered if we would run a big number of applications at the same time. It's probably isn't the best option if you like structure. One idea is to build a off-site lightweight error-handling application that has a REST/JSON API that receives encrypted and serialized arrays of error messages and stores them into a database. Maybe it could, depending on the severity of the error also be directly inputted into our bug tracker. Could be a few well spent hours, but it seems like a quite fragile solution and I am sure that there's better more-reliable alternatives out there already. Thanks,

  • Game Objects Talking To Each Other

    - by PhilCK
    What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the size of projects I was doing. However my projects have been getting bigger in size and complexity and now I want to start re-using code, and making my head a simpler place. The main problem I have is generally along the lines of Player needs to know about the Map and so does the Enemy, this has usually descended into setting lots of pointers and having lots of dependencies, and this becomes a mess quickly. I have thought along the lines of a message style system. but I cant really see how this reduces the dependencies, as I would still be sending the pointers everywhere. Thanks. PS: I guess this has been discussed before, but I don't know what its called just the need I have.

  • Securing paths in PHP

    - by tjm
    I'm writing some PHP which takes some paths to different content directories, and uses these to include various parts of pages later. I'm trying to ensure that the paths are as they seem, and none of them break the rules of the application. I have PRIVATEDIR which must lie above DOCUMENT_ROOT (aka) PUBLICDIR. CONTENTDIR which must lie within PRIVATEDIR and not go back below PUBLICDIR and some other *DIR's which must remain within CONTENTDIR. Currently I set up some defaults, and then override the ones the user specifies and then sanity check them with the following. private function __construct($options) { error_reporting(0); if(is_array($options)) { $this->opts = array_merge($this->opts, $options); } if($this->opts['STATUS']==='debug') { error_reporting(E_ALL | E_NOTICE | E_STRICT); } $this->opts['PUBLICDIR'] = realpath($_SERVER['DOCUMENT_ROOT']) .DIRECTORY_SEPARATOR; $this->opts['PRIVATEDIR'] = realpath($this->opts['PUBLICDIR'] .$this->opts['PRIVATEDIR']) .DIRECTORY_SEPARATOR; $this->opts['CONTENTDIR'] = realpath($this->opts['PRIVATEDIR'] .$this->opts['CONTENTDIR']) .DIRECTORY_SEPARATOR; $this->opts['CACHEDIR'] = realpath($this->opts['PRIVATEDIR'] .$this->opts['CACHEDIR']) .DIRECTORY_SEPARATOR; $this->opts['ERRORDIR'] = realpath($this->opts['CONTENTDIR'] .$this->opts['ERRORDIR']) .DIRECTORY_SEPARATOR; $this->opts['TEMPLATEDIR' = realpath($this->opts['CONTENTDIR'] .$this->opts['TEMPLATEDIR']) .DIRECTORY_SEPARATOR; // then here I have to check that PRIVATEDIR is above PUBLICDIR // and that all the rest remain within private dir and don't drop // down into (or below) PUBLICDIR again. And die with an error if // they don't conform. } The thing is this seems like a lot of work to do, especially as it must be run, every time a page is accessed, before I can do anything else, e.g check for a cached version of the page I'm serving. Part of me is thinking, since all of these paths are predefined by the maintainer of the site, they SHOULD be aware of what paths they are allowing access to and ensuring they are secure. But, I think I'm thinking that because currently I am said maintainer, and I KNOW my paths conform to the rules. That said, I do want to secure this thing from any accidental errors by future maintainers (and I bet, now I've said above "I KNOW...", probably from myself somewhere down the line). This just feels like a suboptimal solution. I wonder how fast this would really be and what you would suggest to improve it or as an alternative? Thanks.

  • How do I submit a form from another page?

    - by Tommy
    I have a two page site. Each page contains a header with "tabs" at the top, to navigate between page 1 and 2. When a tab is selected, I need the selected page to re-POST to the server, to quickly refresh before it is displayed. I have a form on each page that allows a manual refresh from that page but need to submit that form from the other page. For example, page 2 is displayed. The tab for page 1 is selected (which is on page 2) It should then submit the refresh form on page 1. Any help is appreciated. (Using jQuery, js, html and CSS)

  • HTML not updating?

    - by Tommy
    I have a CGI application written in C. When I POST delete data to the app from the html form, the action is correctly executed on the server but the page does not refresh after the POST. It does flicker, but displays the non-updated page. I then have to hit the browsers refresh to see the correct html page. Is this the web server? Javascript? or just a browser setting? (I am using GoAhead web server, cgi app in C, javascript, html and Fire Fox.) Any help is appreciated.

  • Rendering field data as a link in Ruby on Rails...

    - by bgadoci
    Ok, I think this is probably an easy question but for the life of my I can't figure it out. I have created a table called ugtags and in that table I have two columns (beyond the basics), 'name' and 'link'. I am trying to allow a user to add a link to a page. Ideally they would enter the link title (name) and the url (link) and in the view it would display the title as a link to the url that was entered in the link column. I there a way to do it by simply affecting the <%= link_to h(ugtag.name) %> code?

  • jQuery DIV click, with anchors

    - by ANaimi
    To make click-able divs, I do: <div class="clickable" url="http://google.com"> blah blah </div> and then $("div.clickable").click( function() { window.location = $(this).attr("url"); }); I don't know if this is the best way, but it works perfectly with me, except for one issue: If the div contains a click-able element, such as <a href="...">, and the user clicks on the hyperlink, both the hyperlink and div's-clickable are called This is especially a problem when the anchor tag is referring to a javascript AJAX function, which executes the AJAX function AND follows the link in the 'url' attribute of the div. Anyway around this?

  • Are There Any Other Web Programming Languages That Can Be Used Without A Framework Aside From PHP?

    - by Ygam
    Python needs a framework, so does Java (for the web). I don't know much about Ruby or Coldfusion. But is there another language out there for the web that can stand alone as it is without a need for a framework or without strict adherence to a design pattern (MVC and the likes) aside from PHP? BTW, the statement that Python and Java needs a framework to work with the web came purely from my readings on articles and books; I might be mistaken.
