• Is there a security issue with using javascript cookies?

  - by Scarface

  Hey guys, another quick question for the experts. I have an alert box that displays updates processed in php to the user just like this site. I want to make it so that if the user closes the box, then it will not pop up for another 5 minutes (unless they check the messages then it will not pop up because the entries that cause the pop up are deleted in the database). On the close of the box I was thinking of giving the user a javascript cookie, since the alert box is done in javascript. I was wondering if this was a bad coding practice, since I am kind of unfamiliar with cookies and was warned against them before. If anyone has any advice or can recommend a better way, I would really appreciate it.

• How to design websites for all display sizes

  - by katie bekell

  I like to use a lot of unique graphics on my pages, which often results in making different page sizes depending on available screen width/height. Here are two examples: http://www.uvm.edu/~areid/homesite/ - the image floats at the bottom of my screen but on a larger browser, the image floats near the middle making it look off. It looks best when the bottom of the window aligns with the bottom of the image www.stevenlebel.com - it loads two different pages depending on what monitor size is detected. This seems like a lot of redundant coding. My question is, how can I make sliced/Photoshop images transition well to different screen sizes. Does Photoshop allow you to make DIVS instead of tables? Can i make each of the slices created by Photoshop grow/shrink when the browser window size changes? If anyone has any input on creating websites like this I would be very interested to hear what they have to say. Thanks Katie

• Ridiculously Simple Erlang Question

  - by Aiden Bell

  Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and is there any guarantee of order when processing messages? ie. Received in order sent? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

• New/strange Java "try()" syntax?

  - by Ali

  While messing around with the custom formatting options in Eclipse, in one of the sample pieces of code, I say code as follows: /** * 'try-with-resources' */ class Example { void foo() { try (FileReader reader1 = new FileReader("file1"); FileReader reader2 = new FileReader("file2")) { } } } I've never seen try used like this and I've been coding in Java for 9 years! Does any one know why you would do this? What is a possible use-case / benefit of doing this? An other pieces of code I saw, I thought was a very useful shorthand so I'm sharing it here as well, it's pretty obvious what it does: /** * 'multi-catch' */ class Example { void foo() { try { } catch (IllegalArgumentException | NullPointerException | ClassCastException e) { e.printStackTrace(); } } }

• generate all subsets of size k from a set

  - by Kumar

  hi, i want to generate all the subsets of size k from a set. eg:-say i have a set of 6 elements, i have to list all the subsets in which the cardinality of elements is 3. I tried looking for solution,but those are code snippets. Its been long since I have done coding,so I find it hard to understand the code and construct a executable program around it. A complete executable program in C or C++ will be quite helpful. Hoping of an optimal solution using recursion. Thanks in advance. Kumar.

• javascript - how to call a function newly added from ajax

  - by strike_noir

  I have a coding difficulty which have been asked in this forum before: Calling a JavaScript function returned from a Ajax response But I didn't find the answers quite satisfying. To be more precise of the problem I'm dealing, here is the details: I dynamically load a document (HTML and javascript) using jquery var url = 'document.php'; $('#container').load(url); And then I want to call the functions from that document.php. Due to my requirement, I don't want to call the function after the documents' loaded, but rather to call it later when I need it. Because it was dynamically loaded, the DOM doesn't recognize the functions. How to properly call this function? Thank you

• Appropriate Footwear for An Interview

  - by EoRaptor013

  There's a raging debate going on at my house about appropriate footwear for an IT interview. I have an interview, on Thursday, for a SQL/C# developer with the Fraud dept. at a large accounting firm. I was planning on wearing what I have pretty much always worn for an interview: a nice suit, white shirt, subdued tie, and a pair of dress cowboy boots. My spouse and daughter both know that my dress code for nearly every professional job I've ever gotten, is pretty much the same -- including the boots -- with what I just described. Now, however, because I've been out of work for an unfortunately long time (my last contract ended 03/09 -- pretty much coincidental with the bottom falling out of the economy). My wife insists that style standards are fundamentally different on the left side of the Mississippi vs. the right side of the river. My view is that I've always worn "cowboy" boots; since I was old enough to fit into a real pair. I moved East, as an adult, over 30 years ago, but my dress patterns haven't changed. And in all that time, my dress patterns have never changed. Now I both really want, and really need, this job. But, is that sufficient reason to change a habit 40 years in the making? I would really appreciate the thoughts ya'all (little West of Ms. colloquialism, there) might have on this matter. Thanks. P.S. If this sort of question is inappropriate for this form, I apologize.

• Netbeans GUI Form corrupted?

  - by hubpages-my

  I was making a java gui application through netbeans IDE. All was working fine but yesterday when I opened the form in Netbeans, it said that the form had been corrupted and it could only open that form in read-only mode. When I opened that form in read-only mode, I found that the code was incomplete as severals lines of coding wasn't there at the end. Could anybody tell me how to recover the form. The form is perfect in lookwise but the generated code is incomplete. The code is too long to write it again. The Netbeans told me to get help from http://wiki.netbeans.org/FormGuardedBlockError but I didn't find any helpful information there.

When I use some type and go ahead with coding but on next step, there are in-build functions that use other types & it always require to convert one type of string to other. I found so many blogs but so confused when see so many answers & try but some are working & some are not. Please give your answer or links that gives ultimate solution for handling different types of strings in visual c++.

• How to programmatically blur an area in a movie (in python) ?

  - by Stefano Borini

  I have a movie, and I want to produce a new movie out of it with an area blurred (e.g. an object, a writing or a face). The area is moving, so I must have fine control of the current frame and move the position of the blur area accordingly. Blur is an option, but also a dark mask is fine too. Now, I have a question open at superuser on which software to use, but since I suspect I will have to buy adobe premiere to do something like this, and I don't want to shell out a kidney for something I have to do once, I am thinking about coding it myself in python. What are the best libraries available for this task ?

• customisable JSLint

  - by Don

  Hi, I'm looking for a tool that checks JS code, which can be integrated into a Maven build. I need a tool that will check for errors such as use of reserved words as identifiers trailing semi-colon, e.g. var obj = { a: 1, b, 2, } JSLint seems like a perfect candidate, but the problem is that it is too strict, because it also checks for various coding patterns which are (arguably) bad style, but do not actually generate errors in a browser. Examples of such issues include Disallow ++ and -- and Allow one var statement per function If possible, I would like the errors to fail the build, and I would like the other rules to only print warnings (or disable them completely). Obviously, I need the ability to specify which of the available rules I consider errors and which I consider warnings. Thanks, Don

• Should a developer be a coauthor to a paper presented about the application they developed?

  - by ved

  In our organization, project teams come up with a need and funding and developers are given a basic scope and are allowed to develop the solution. There is a certain degree of implementation freedom given to the developers. They drive the solution to pilot and live deployment from its inception. If the solution is presented in a conference as a technical paper/white paper what is the protocol for the list of authors: because for the most part I see the project manager's and the dev team manager's names as authors but no mention of the actual developer. Is this correct? A lot of us developers feel pretty bummed to never see our names as the coauthors. Appreciate any pointers. Answers to the FOLLOW UP questions (1) in what field of study is the paper, and what are the standards of authorship for that field? The paper is for Flood Plain Management - there is nothing on the abstract guidelines, I have called the contact person listed for comment - waiting to hear. 2) was the paper literally about the software application as your question implies, or were the software issues incidental to the topic of the paper? The paper specifically deals with a GIS Application that is used in Coastal Engineering, yes the software is not incidental, but the meat of the paper and mentioned in the Title. 2

• Alternatives to java on android

  - by user84584

  Hello guys, I just got myself an android phone and I'm dying to start coding on it ! However I'm not a big java fan, although I can live with that, I would like to know if there're reasonable alternatives for the android virtual machine. I've done a medium sized project using clojure, however from the reviews I read, it's very slow when running on android. How about scala ? I read that some people did experiments with it in android, is it "fast enough" ? How big is the learning curve ? Cheers, Ze Maria

• Custom XAML property

  - by Scott Silvi

  Hey all - I've seen a library that allows me to do this inside my XAML, which sets the visibility of the control based on whether or not the user is in a role: s:Authorization.RequiresRole="Admin" Using that library with my database requires a bunch of coding that I can't really do right now. Ultimately here's what I want to know... I have received the authenticated users role from my SPROC, and its currently stored in my App.xaml.cs as a property (not necessary for the final solution, just FYI for now). I want to create a property (dependency property? attached property?) that allows me to say something very similar to what the other library has: RequiresRole="Admin", which would collapse the visibility if the user is not in the Admin role. Can anyone point me in the right direction on this? Thanks, Scott

• C# if statement. inner workings Q

  - by Mike Mengell

  I've just come across this code snippet in some Exchange 2010 code and I was wondering if anyone knew why the programmer has done it this way. I've never seen an If statement formatted like this. It seems so backwards there must be a good reason for it?? if (true == MsgItem.HasAttachments) { // Code } I'm assuming it might have some optimisation over the various other ways of coding the same thing; if (MsgItem.HasAttachments) { // Code } or if (MsgItem.HasAttachments == true) { // Code } Its not a big deal I'm just curious. Thanks, Mike

• TFS: Managing assembly version number?

  - by TomTom

  Hello, any good approach for managing assembly version numbers in TFS, possibly together with using the same number for the build number? I would be most interested in an approach that: Maintains the first three elements of the version Counts the rest upward for every "official" build (i.e. a build originating from certain templates only - no need to count up for something like a gated checkin, but the following regular integration build SHOULD count up. Labels the builds, so that a manual "release" build can be triggered. Any solution? How are other people handling this? Right now the (new) TFS is happily building with the same assembly version all around ;) Something coding the complete assembly version with date etc. is not acceptable - I want that number to "follow rules", and having the date in there is not one of them ;)

• yet another confusion with multiprocessing error, 'module' object has no attribute 'f'

• How do I get started on a bigger project?

  - by Axilus

  Hey guys, Most of the time I have been programming little apps either for myself or for the benifit of learning. Now that my programming skills are considered somewhat intermediate, I was wondering how I would tackle a large programming project. Lets suppose I wanted to make an application that has a lot of features and is intended for the use of others and not just myself; how do I go about planning for such projects? Do I just jump in and start coding the thing or is there some sort of recommended process? Thanks in advance :D

• Best Practice: Access form elements by HTML id or name attribute?

  - by seth

  As any seasoned JavaScript developer knows, there are many (too many) ways to do the same thing. For example, say you have a text field as follows: <form name="myForm"> <input type="text" name="foo" id="foo" /> There are many way to access this in JavaScript: [1] document.forms[0].elements[0]; [2] document.myForm.foo; [3] document.getElementById('foo'); [4] document.getElementById('myForm').foo; ... and so on ... Methods [1] and [3] are well documented in the Mozilla Gecko documentation, but neither are ideal. [1] is just too general to be useful and [3] requires both an id and a name (assuming you will be posting the data to a server side language). Ideally, it would be best to have only an id attribute or a name attribute (having both is somewhat redundant, especially if the id isn't necessary for any css, and increases the likelihood of typos, etc). [2] seems to be the most intuitive and it seems to be widely used, but I haven't seen it referenced in the Gecko documentation and I'm worried about both forwards compatibility and cross browser compatiblity (and of course I want to be as standards compliant as possible). So what's best practice here? Can anyone point to something in the DOM documentation or W3C specification that could resolve this? Note I am specifically interested in a non-library solution (jQuery/Prototype).

• Best Technologies for AJAX Web Development

  - by floatingfrisbee

  Hey Everyone, I have some experience in AJAX development, mostly on .NET and MooTools. However, I want to learn more and see what others out there thought about the various other options available. I am looking more for advise about the front end. The back end, I will most probably be coding up in .NET using c# and WCF services. Please feel free to provide me as much information as you can. Also I would appreciate any links to resources. List of Options (feel free to add) Write my own Javascript Use a frame work like MooTools, JQuery etc. Which one is better? Use Google Web Toolkit. Am I tying myself to limitations of GWT? Or are there not limitations? ASP.NET AJAX WPF (Will this run on non IE browsers?) Flash (it'll be a pain to learn action script) Thanks Jaspreet

• Manifesto for Integrated Development Environments

  - by Hugo S Ferreira

  Have you recently take a peek at Coda, or Espresso, or Textmate? Or even Google Chrome's Developer Tools? They are well designed, intuitive, interface rich, and extensible. But Coda, Espresso or Textmate, among several, are text editors, not IDEs. On the other side, VIM and Emacs live in the last century, and Eclipse is an overbloated platform. This is more like an outcry for a decent, common infrastructure for REAL IDEs. But there's some questions attached: (i) what features are needed for such a product and (ii) what products are out there that could fullfil this need, and what are they missing. So here's my draft for a manifesto: Manifesto for Integrated Development Environments: We favor interactivity and productivity over syntax and tools. We favor inline, contextual documentation over man and html files. We favor high-definition, graphic-capable color screens over 80x25 character terminals. We favor the use of advanced input schemas over unintuitive keyboard shortcuts. We favor a common, extensible and customizable infrastructure over unmaintained chaintools. We know the difference between search&replace and refactoring. We know the difference between integrated debugging support over a terminal window. We know the difference between semantic-aware code-completion over dumb textual templates. We favor the usage of standards like (E)BNF.

• How to (kindly) ask your users to upgrade from IE6?

  - by nickf

  It's no secret at all that IE6 has been a major roadblock to the advancement of the web over the last few years. I couldn't count the number of hours I've spent bashing my head against a wall trying to fix or debug IE6 issues. The way I see it, there are two types of IE6 user. a) the poor corporate schmoe whose IT department doesn't want to upgrade in case something breaks, and b) the mums and dads of the world who think the internet is the blue E on their desktop (and I don't mean that in a nasty way). There's probably a couple of people who know about all the other browsers, but still choose to run IE6. They get what they deserve, IMO. Anyway, getting to the point, I'd say that 90% of my IE6-using visitors are in the the mums and dads category - they're not stupid, they just don't know WHY they should upgrade to IE7 or Firefox or whatever. How do I educate these people without pissing them off? Is there a nice and friendly website I can direct these people to, which explains the reasons for upgrading in plain language? Any mention of "security" or "web standards" I think would just come across as scary. I've just seen http://www.whatbrowser.org which seems to fit the bill nicely. It explains in very basic terms: what a web browser is why you'd want to upgrade it how old your current browser is (subtle hint to those with a 9 year old browser) ..aaaand it's in 22 languages. It's from Google but displays no bias (it links to Firefox, Chrome, Opera, Safari, Internet Explorer displayed in a random order).
