• What features would you like to have in PHP? [closed]

  - by StasM

  Since it's the holiday season now and everybody's making wishes, I wonder - which language features you would wish PHP would have added? I am interested in some practical suggestions/wishes for the language. By practical I mean: Something that can be practically done (not: "I wish PHP would guess what my code means and fix bugs for me" or "I wish any code would execute under 5ms") Something that doesn't require changing PHP into another language (not: "I wish they'd drop $ signs and use space instead of braces" or "I wish PHP were compiled, statically typed and had # in it's name") Something that would not require breaking all the existing code (not: "Let's rename 500 functions and change parameter order for them") Something that does change the language or some interesting aspect of it (not: "I wish there was extension to support for XYZ protocol" or "I wish bug #12345 were finally fixed") Something that is more than a rant (not: "I wish PHP wouldn't suck so badly") Anybody has any good wishes? Mod edit: Stanislav Malyshev is a core PHP developer.

• How much should I charge for a web app

  - by Kostas

  I am a freelance web developer and I am working on a PHP/MySQL/Javascript based project. It's a web app that uses a custom CMS with user types, followers system, search forms, blogs, social integration. It will take about 3 months to finish, according to a roadmap I make (based on current development stage) and about a month after that for bug fixing and testing. So I have to tell them a price. What price range you think it's appropriate?? (It's a good regular client, so I want something reasonable) Can you give me some ideas?? Thanks.

• Parleys Testimonial at GlassFish Community Event, JavaOne 2012

  - by arungupta

  Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world. Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user. Recently they migrated their application from Spring to Java EE 6. This allows them to get locked into proprietary frameworks and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there. Watch the video below showing him in full action: More details about their infrastructure is available here.

• Avoiding duplicate bug reports

  - by Jaakko Seppälä

  I use Linux and other open source software in my home. As I'm not a professional coder, I usually report bugs to developers as my skills are not enough to solve problems on my own. What kind of things you want me to check before I send a bug report? I mean, once I thought I found a bug in Gedit and I couldn't find similar bug in Bugzilla. But after I sent the report, some developer said that the bug is already in Bugzilla as the bug was in GTK+, not in Gedit. Sometimes it might be hard for an amateur to guess whether some previously known bug would solve the issue I found.

• Author's work and copyright. in UI design

  - by c-smile

  Typical situation in UI design: you do design of some UI and, say, came up with some bright new idea like "ribbon" or "kinetic scroll past end". What would be the strategy about such thing? Register patent, don't like it, but anyway would like to ask: how long it takes to do all this stuff and how much it will cost in average? If to forget about patents, will the idea have something like "prior art" status or some such if someone will try to patent this in future? All this about project / product published by solo developer.

• Best practices for including open source code from other public projects?

  - by Bryan Kemp

  If I use an existing open source project that is hosted for example on github within one of my projects, should I check in the code from the other project into my public repo or not? I have mixed feelings about this, #1 I want to give proper credit and attribution to the original developer, and if appropriate I will contribute back any changes I need to make. However given that I have developed / tested against a specific revision of the other projects code, that is the version that I want to distribute to users of my project. Here is the specific use case to illustrate my point. I am looking for a more generalized answer than this specific case. I am developing simple framework using rabbitmq and python for outbound messages that will allow for sending sms, twitter, email, and is extensible to support additional messaging buses as well. There is a project on github that will make the creation and sending of SMS messages developed by another person. When I create my own repo how do I account for the code that I am including from the other project?

• MAKE CROSS THREAD METHOD CALLS USING INVOKE METHOD OF THE CONTROL

  Cross threading is a phenomina normally happening in any of application debug session. Developer may not able to understand what's this all about. He may not actually coded for any such scenario like Threading. But this exception may raise especially in side a method where you are accessing any of the GUI control menthod. One natural scenaio will happen, once you are handling with FielSystemWatcher class. But here 1st I will create a sceanrio and then will give you 2 way resolution too.

• Is there a term for "Use procedures that execute a single task"?

  - by Tom

  I'm having a discussion with a fellow developer, and I'm trying to argument this in something like a short "term". SoC (Separation of Concerns) is pretty straight forward design practice, but it dwells deeper. If we want to pick on it's deep corners, we can Google it and there are plenty of articles that pop up, and after taking a glimpse, we know a lot more, and might find some examples. But, what about "Use procedures that execute a single task"? That's also a great design principle to use when writing applications and it becomes more and more rewarding, the larger the application gets. Is there a term for Use procedures that execute a single task?

• how to learn Java

  - by Sarang

  This question I am asking because I couldn't find any source which gives complete overview of java development. I just want to know where java technology currently in market & what is preferable for development ! Java always remain top programming language for development point of view. However, java is combo of, j2ee, j2me, jsp, jsf, spring, other frameworks, ui components, jndi, networking tools and various other "J" are there ! However, learning java is definitely dependent on the development requirement, but still, to be a well-experienced java developer, what is the organised way of learning java? What is preferable in current technology ? and what is deprecated, currently ?

• How to ramp up my data structures skills after a long hibernation

  - by Anon

  I was pretty good with algorithms and data structures once, a long long time ago. Since then, I programmed professionally, and then went to manage a small team, which totally shot my tech skills in this field back. I've decided I want to be a developer again, and work for Google. The thing is, I'm so out of practice, that if I were to be interviewed right now I would surely flunk out in 10 minutes. What training program would you recommend for me to get back into shape? I already started this weekend by going back to the absolute basics and implementing a few sort algorithms, linked list, and hash table. Next, I think I'll read through the entire course material on the other basic data structures and graph algorithms. I want to find a focused set of practical exercises I can do in a relatively short amount of time, to juggle the old brain cells. I know this stuff - I just need to remind myself that I know it.

• Setting up Developers Conference

  - by Darknight

  In our local city in the UK, there are as far as I am aware no developer conferences. I am confident that our region has many professional developers as well as many graduating students whom who really benefit from a conference. I would like to ask the following questions: What steps or advice would one take if the task was given to set up a local developers conference? What would the costing look like? (excluding building/hosting of website(s)) How would one build interest and promote this? How would I approach, Local Companies & Universities to collaborate with them? I'm not just aiming this question to users who may have experience in setting up such conferences (but are highly welcome). Rather how would you attack this if you was tasked with this?

• Software development, basics of design, conventions and scalability

  - by goce ribeski

  I need to improve my programming skills in order to achieve better scalability for the software I'm working on. Purpose is to learn the rules of adding new modules and features, so when it comes to maintaining existing ones there is some concept. So, I'm looking for a good book, tutorial or websites where I can continue to read about this. Currently, what I know and what I do is: to design relational database(3NF), make separate class for each table put that in MVC implement modular programming ...write code and hope for the best... I presume that next things I need to learn more deeply are: programming codex(naming, commenting, conventions...), organize functions building interfaces organizing custom made libraries, organizing API that I'm using, documenting, team work... ... At last what my job is, it does't need to affect your answer, PHP CodeIgniter developer.

• Have you downloaded the All-In-One Code Framework?

  - by Eric Nelson

  The Microsoft All-In-One Code Framework is a free, centralized code sample library provided by the Microsoft Community team. It aims to provide typical code samples for all Microsoft development technologies. The team listens to developers’ pains in MSDN forums, social media and various developer communities and write code samples based on developers’ frequently asked programming tasks. Additionally, our team offers a free code sample request service. Awesome?! I think so. Have also just added it to 99 technical resources for developers and architects inside ISVs – also worth checking out. Check it out on codeplex

• How can I get started programming OpenGL on Mac OS X?

  - by Michael Stum

  I'm trying to start OpenGL programming on a Mac, which brings me into unknown territory on a lot of things. During the day, I'm a Web Developer, working in C# and before that in PHP and Delphi, all on Windows. During the night, I try to pick up Mac/OpenGL skills, but everything is so different. I've been trying to look for some books, but the OpenGL books are usually for iOS (tons of them out there) and the Mac Books usually cover "normal" application Development. I want to start simple with Pong, Tetris and Wolfenstein. I see that there are a bunch of different OpenGL Versions out there. I know about OpenGL ES 1&2, but I don't know about the "big" OpenGL Versions - which ones are commonly supported on 10.6 and 10.7 on current (2010/2011) Macs? Are there any up to date (XCode 4) books or tutorials? I don't want to use a premade Engine like Unity yet - again, I know next to nothing about any Mac development.

• StreamInsight Licensing

  I cannot help but think that this is currently wrong.  There are two editions of StreamInsight (SI), Premium and Standard.  A link to their differences is here Points to note Developer Edition and Evaluation Edition represent Enterprise Edition in SQL Server but not SI where they represent Datacentre Edition.  Won’t this be confusing when people evaluating SI find that it is not the same animal when they move to Enterprise Edition? If SI Premium is the only thing you want out of the SQL Server box then it is going to be a high cost. The latency rates as well quoted on the site above make Premium Edition essential if you are going to be using this to do Real-Time analytics.

  EDIT: I should clarify. THe particular terms I listed below I fully understand. I also understand w3schools doesn't have the greatest information. These are just examples. I don't expect everybody to understand what an example is, but I hope the majority do. Does anybody have any resources listing terms related to programming and web development, or care to pitch in? Things like: Runtime Build time Framework Library Normalize I'm primarily a PHP developer so anything about that. I really am looking for general terms and specific terms related to web development, PHP, SQL, CSS, HTML. Appreciate any input.

• Iterating selected rows in an ADF Faces table

  - by Frank Nimphius

  In OTN Harvest May 2012; http://www.oracle.com/technetwork/developer-tools/adf/learnmore/may2012-otn-harvest-1652358.pdf I wrote about "Common mistake when iterating <af:table> rows". In this entry I showed code to access the row associated with a selected table row from the binding layer to avoid the problem of having to programmatically change the selected table row. As it turns out, my solution only worked fro selected table rows that are in the current iterator query range. So here's a solution that works for all ranges public String onButtonPress() { RowKeySet rks = table.getSelectedRowKeys(); Iterator it = rks.iterator(); while (it.hasNext()) { List selectedRowKeyPath = (List)it.next(); //table is the JSF component reference created using the table's binding //property Row row = ((JUCtrlHierNodeBinding)table.getRowData(selectedRowKeyPath)).getRow(); System.out.println("Print Test: " + row.getAttribute(1)); } return null; }

• What are the most important programming skills you need to improve as a team Leader or project manager?

  - by Aba Dov

  I decided to ask this question after I read the valuable answers to the great question What is the single most effective thing you did to improve your programming skills? and after attending Ad Burns "Secrets of a rock star programmer". It made me think about me and what programming skills I try to improve. I came to realize that there should be a difference in the programming skills you try to improve as developer and the programming skills you should improve as a team leader or project manager. My question is: What are the most important programming skills you need to improve as a team Leader or project manager? What would you recommend to others that want to improve?
