• Screencast: "Unlocking the Java EE Platform with HTML5"

  - by Geertjan

  The Java EE platform aims to increase your productivity and reduce the amount of scaffolding code needed in Java enterprise applications. It encompasses a range of specifications, such as JPA, EJB, JSF, and JAX-RS. How do these specifications fit together in an application, and how do they relate to each other? And how can HTML5 be used to leverage Java EE? In this recording of a session I did last week at Oredev in Malmo, Sweden, you learn how Java EE works and how it can be integrated with HTML5 front ends, via HTML, JavaScript, and CSS.

• Which MIME type to compress? and what If I omit the `type` attribute from the HTML?

  - by rockyraw

  Per my request, my webhost had turned mod_deflate ON. In my Cpanel I now have an "Optimize Website" button. Inside that menu I could either choose: "Compress all content" or "Compress the specified MIME types" with the following default MIME types: "text/html text/plain text/xml" Which option should I choose and why? If I choose option 2, which types should I add (is there a recommended list with the exact way they should be written)? According to Google recommendations, I have omitted the type="text/css" attributes from all CSS references, as well as the type="text/javascript" attributes from all script references. Would this hinder the "gzipping" process?

• .htaccess and browser caching

  - by Tim

  I ran across these suggested htaccess edits. Is this a good practice? Is this something I should implement on my wordpress site?: <IfModule mod_expires.c> ExpiresActive On ExpiresByType image/jpg "access plus 1 year" ExpiresByType image/jpeg "access plus 1 year" ExpiresByType image/gif "access plus 1 year" ExpiresByType image/png "access plus 1 year" ExpiresByType text/css "access plus 1 month" ExpiresByType application/pdf "access plus 1 month" ExpiresByType text/x-javascript "access plus 1 month" ExpiresByType application/x-shockwave-flash "access plus 1 month" ExpiresByType image/x-icon "access plus 1 year" ExpiresDefault "access plus 2 days" </IfModule>

• HTML5 est-il adapté pour les jeux ? La puissance et les pièges du langage explorés lors d'un événement parrainé par Google et Microsoft

  HTML5 est-il adapté pour les jeux sur le Web ?

• How can I get stats for what 3rd-party sites have embedded our iframe widget?

  - by Su'

  Say we've produced a widget for other sites to use, like so: <iframe src="http://example.com/whatever.php" frameBorder="0" width="200px" height="300px" scrolling="no"></iframe> The client would like to be able to see within GA who has embedded the thing. Is there some referer information automatically passed that I can look for, or do I need to add something? whatever.php is already loading the analytics Javascript(we're also tracking clicks on an outbound link). [EDIT] Looking around a bit more, I found what seems to be a similar question on SO with an answer saying this can be found, automatically, but I still can't seem to find the information. The question's also old enough the respondent is probably referring to the old interface, though. Maybe someone could explain getting to it in the new look. (I won't likely be able to train this client to switch, deal with the old look, etc.)

• La première version du SDK de Dart sort, le langage structuré pour le Web de Google est prêt à l'emploi

  Dartium : Google publie une préversion de Chrome avec la machine virtuelle Dart son langage structuré pour le Web Mise à jour du 17/02/2012, par Hinault Romaric Google vient de publier une préversion ( technical preview) pour les développeurs de Dartium, un navigateur à base de Chrome qui introduit la machine virtuelle Dart.

• What things need to be considered when redeveloping the whole UI for a web app?

  - by Robin

  I am the lead developer on a thick client web app (Java swing) which we're looking at recreating as a web app. We're part way through some initial work, have chosen a framework on the server and integrated with our previous backend code. We're just starting to get into the client side of things, looking at javascript frameworks etc. The previous system was pretty sensibly architected so the logic is already serverside. The challenge ahead of us is really about redeveloping the user interface rather than anything else. What would be the list of things to consider in redeveloping the entire user interface for any application? I'm trying to get an idea of how large a task might still be ahead of me and the team.

• Too much to learn, dealing with overwhelming varieties of technologies [closed]

  - by zhenka

  I am about to graduate, and I am already working as a web developer in our library IT department. When I look at job postings I am absolutely overwhelmed by the sheer variety of technologies out there. Some companies care about math + algorithms + data structures. Some care about experiences in technology stack XYZ. SQL, css, html, frameworks, javascript, design patterns etc.. etc... etc... At some point I realized I just need to start at mastering a foundation to become employable at a better place and go from there. But the skill-set to get me in the doors varies and I just don't have time to learn everything. How do you deal with this issue? What is the essential stack to become employable? Say in php or ror arena. Perhaps a smarter move would be to move to a technology stack with less variety like .net?

• More complex learning source for C# .NET [closed]

  - by Leron

  By complex I don't mean more difficult but including a larger area of possibilities cover. I've started a few years ago with PHP and the transition from learning the syntax of the language and the basic logical structures to working with databases, including JavaScript and so on was very short. And now I'm more interested in studying working with languages like Java/C#. Recently I spend a lot of time reading and writing some simple console applications, I've read almost 2K pages for C# programming and still don't know how to connect to database for example. Just for info I'm interested in web development, socket programing and live streaming, don't know if I'm exceeding myself too much writing that but despite that I want to find some books/internet sources where I can extend my current knowledge of C#/.NET, start using database queries, maybe try something more complicated webwise.

• How can I build this payment receipt/booking application?

  - by Festus

  I'm planning to build a payment receipt/booking application for a media company with several branches in different locations. The application should be able to move data across the network/internet to a central database where the administrator/accountant in a different location will be able to see the result of the entire job for the day from each branch. Application will run on windows environment. Will be able to send result of the booking to a Point Of Sales printer for print output. Now, I'm confused about choosing the right programming language to accomplish this task. I'm between beginner/intermediate level in PHP, I know HTML/CSS and JavaScript. I have tried to do this in PHP but, I'm face with several challenges and I fear for the POS part since PHP application run on the web browser. I don't know if python will be best suited for this and how long will it take someone with my experience level to pick up python. Any suggestion will be highly appreciated.

• What causes Google Analytics tags to work on some machines but not on others?

  - by Dallas

  The title of this question says it all. I am trying to update my code from the deprecated _getTracker() method to _createTracker(), but am experiencing inconsistent results. I have tried traditional and Asynch methods using a JSP include, but they all have the same result. My pageviews, and others in the office all show up in analytics. I have tried various test cases, but their visits are just not registering at all for them, but are showing up for me. The client has tried on multiple machines, and I have walked through with them step by step, so I know it's not just user error. I know that javascript being turned off will cause the tags not to work, but I am wondering if what else might cause the tags to not be recognized. I would appreciate any and all ideas.

• What makes a language (or feature) "hackerish"?

  - by iCanLearn

  I was reading the comments and answers to this question, and among them I found this: "And Java never was cool, simply because it threw the hacking part out of programming" and this: "And javascript is very hackerish language so after developing your frontend you feel very constraint when you return to java." What's the "hacking part" in programming, and what makes a language "hackerish"? What are some good examples of languages and features in languages that you would call "hackerish"? (Someone might say that I shouldn't be confused by the word "hackerish", that's it's not really a "proper" English word or something like that, but that's besides the point)

• Intersection of player and mesh

  - by Will

  I have a 3D scene, and a player that can move about in it. In a time-step the player can move from point A to point B. The player should follow the terrain height but slow going up cliffs and then fall back, or stop when jumping and hitting a wall and so on. In my first prototype I determine the Y at the player's centre's X,Z by intersecting a ray with every triangle in the scene. I am not checking their path, but rather just sampling their end-point for each tick. Despite this being Javascript, it works acceptably performance-wise. However, because I am modeling the player as a single point, the player can position themselves so that they are half-in a cliff face and so on. I need to model them as as a solid e.g. some cluster of spheres or a even their fuller mesh. I am also concerned that if they were moving faster they might miss the test altogether. How should I solve this?

• How to prevent a search engines from indexing a section of a page?

  - by BrunoLM

  I have many pages with lots of text in it. But I will always have two sections of text and I want to prevent one section from appearing in search results, the other section must be indexed. <p class="please-index-me">text</p> <p class="get-out">never index me please</p> I thought that maybe if I load the "please don't index me text" with Javascript maybe search engines wouldn't look for it. But I am not sure it would work and this is not really nice. I was wondering if there is a way to tell search engines "hey, this text you can't grab, move on". So, is there a way to do it?

• .NET - Where can I start? [closed]

  - by mustang2009cobra

  I'm a moderately experienced developer with experience developing using a variety of languages. I've done C++, Java, PHP, Javascript, and several other languages. I remember the Java dev stack being rather difficult to dive into, but it's nothing like the endless sea of the .NET framework. I'd like to become experienced in .NET development, as many dev shops are microsoft-centric. But I'm a little unsure as to where the best place to start is. As I already know a bunch of programming languages, I don't really need resources that will help me learn C# or any of the .NET languages as much as I need to learn the development stack, APIs, etc. Any suggestions on the best way to start learning .NET development?

• When going for an interview for web development at an agency, can a real example be expected?

  - by KPO

  I just started coding a year ago. By "coding" I mean HTML(5), CSS(3), and only a few times I implemented AJAX and JavaScript. I am interviewing for a position that expects me to know HTML, CSS, JS, JQuery, and AJAX. I am good with HTML5/CSS3 and somewhat ok with js. If I go for an interview, will they expect me to write code during the interview? I do have a live website as an example and snapshots of past projects that I sent to them. I am a little nervous, so any tips or something from your experience I can learn will be helpful.

• Lost in Code?

  - by Geertjan

  Sometimes you're coding and you find yourself forgetting your context. For example, look at this situation: The cursor is on line 52. Imagine you're coding there and you're puzzling on some problem for some time. Wouldn't it be handy to know, without scrolling up (and then back down again to where you were working), what the method signature looks like? And does the method begin two lines above the visible code or 10 lines? That information can now, in NetBeans iDE 7.3 (and already in the 7.3 Beta) very easily be ascertained, by putting the cursor on the closing brace of the code block: As you can see, a new vertical line is shown parallel to the line numbers, connecting the end of the method with its start, as well as, at the top of the editor, the complete method signature, together with the number of the line on which it's found. Very handy. Same support is found for other file types, such as in JavaScript files.

• Java EE @ NFJS Central Iowa Software Symposium Des Moines

  - by reza_rahman

  As some of you may be aware I recently joined the well-respected US based No Fluff Just Stuff (NFJS) Tour. The NFJS Central Iowa Software Symposium was held August 8 - 10 in Des Moines. The Des Moines show is one of the smaller ones but still was good overall. It is one of the few events of it's kind that take place this part the country so it is extremely important. I had five talks total over two days, more or less back-to-back. I had decent attendance for all my sessions and had many of the same folks staying for multiple sessions which is always a very good sign. I did talks on Java EE 7/Java EE 8, WebSocket, the Cargo Tracker Java EE Blue Prints, JavaScript + Java EE and NoSQL + Java EE. More details, including slide decks and code as well as my NFJS tour schedule, posted on my personal blog.
