• Does anyone actually use the /// comment blocks?

  - by Rachel

  Someone once said we should prefix all our methods with the /// <summary> comment blocks (C#) and I am wondering if that is true or not. I started to use them and found they annoyed me quite a bit, so stopped using them except for libraries and static methods. They're bulky and I'm always forgetting to update them. Do you recommend using them? Why? EDIT: I normally use // comments all the time, it's just the /// <summary> blocks I was wondering about

• Building a Store Locator ASP.NET Application Using Google Maps API (Part 2)

  Last week's article, <a href="http://www.4guysfromrolla.com/articles/051910-1.aspx">Building a Store Locator ASP.NET Application Using Google Maps API (Part 1)</a>, was the first in a multi-part article series exploring how to add store locator-type functionality to your ASP.NET website using the free <a href="http://code.google.com/apis/maps/">Google Maps API</a>. Part 1 started with an examination of the database used to power the store locator, which contains a single table named <code>Stores</code> with columns capturing the store number, its address and its <a href="http://en.wikipedia.org/wiki/Latitude">latitude</a> and <a

• What options do individual have to fork a project?

  - by skrco

  Let's assume our example individual has an idea, engagement, ... to fork project. By project I mean any kind of software - thick client, web site, portal, service, driver, plc, ... - anything that can be programmed. Motto of question: What options do our example individual have to fork this project from the early beginning through getting collaborators and users to mature software? Here are the main subquestions: Sandbox phase: Where can he announce his idea and proposal and receive positive/negative critic and feedback? Development phase: Where can he build his team to work on this project? Yet deployed phase: Where can he schedule tasks, assign tickets and bugs to be solved? and the list can go on... What really interests me is the "sandbox phase question".

• Advantages and disadvantages of libgdx [on hold]

  - by Paul

  I've been an android developer for a while and am thinking about getting into gaming. While looking for a game dev framework, I thought libgdx provides very friendly documentation and functionality. So I would like to use it if there is no big obstacle. But when I tried to see how many developers employ this library, I could find not that many. Is there anything wrong with this library? In other words, I would like to know its advantages or disadvantages from any experienced developer. UPDATE: After reviewing its documentations and trying to build simple games with libgdx, I decided to go with it as its documentations are good enough and its community is very active. What I liked the most is that it provides a bunch of demo games that I can learn a lot from.

• Add Custom Launcher in 11.10

  - by sayth

  I started by searching guides. I found this guide but neither of the main methods works anymore in 11.10. The first solution, I have created the desktop file, however the file location given as .gconf-> desktop-> unity-> launcher -> favourites no longer exists. I can get to /home/sayth/.gconf/desktop but there is no longer a unity folder. The second solution described right-clicking the desktop and creating a launcher. Right-clicking the desktop no longer produces a "create a launcher" option. I manually installed geany 0.21 as the one in the repo's is outdated. It's installed and working correctly, and is executing from /usr/local/bin/geany. How can I add it to the launcher?

• How do I remove my Facebook account from Gwibber?

  - by Marius Krinnan

  I started using Ubuntu 12.10 today, and put in my social networking details in Online Accounts under System Settings. I like being able to chat with my Facebook friends in Empathy, but I don't necessarily want my tweets to go to Facebook. I want to remove Facebook from Gwibber, but not Empathy. How do I do this? There is nothing in Gwibber preferences and I can't see how to do it in Online Accounts. The reason I want to remove it is that it isn't clear enough which accounts are posted to and I don't necessarily want the feeds mixing together.

• Ouya build experiencing odd graphical artifacts, screen half black

  - by Neeko

  I'm witnessing very odd graphical artifacts when I run my Unity game on Ouya. After the Unity splash screen, the game loads with the screen half black. This seemingly has started occurring out of the blue. It also doesn't occur in the editor or the standalone build, only on Ouya. I can't think of a single reason why this would be happening. If I open the Ouya menu screen and close it, the game returns to normal; somewhat, as there may be some artifacts lingering but the screen isn't half black like in the screen shot above. I know there's not much to go off of, but any insight into why this may be happening is greatly appreciated.

• Automatically analyze excel files

  - by dole doug

  I have to replicate a manual generation of a large number of excel files. I started to manually track the relations between cells ( files, formulas, etc). I also had a talk with the person which generates those files. For now I have a general understanding about how the excel files are generated, but "devil is in the details". I assume that I can write a script which will generate the hierarchy between cells and files, but this might require the same effort as manually noticing the relations. Also, I'm afraid that I'm not too experienced and my app is more prone to error approach than a manual analyze. How to handle this problem? Do you know about an open source project which analyze the excel files in a recursive mode following the formulas ?

• Routing PHP memcached calls to Oracle Coherence

  - by cj

  A new post Getting Started with the Coherence Memcached Adaptor from David Felcey shows how PHP memcached calls can automatically be routed to store data in Oracle Coherence 12c. This is possible now Coherence 12.1.3 supports Memcached clients using the Binary Memcached protocol. David's post shows how the Coherence Memcached adaptor can be configured as a proxy service that runs in the Coherence cluster. There's nothing particular to configure in the PHP application, except to enable memcached.use_sasl = 1 So what is Coherence? It is an "in-memory data grid solution", with a number of advanced features. You can read more in the Oracle Coherence 12C Data Sheet.

• Gnome Classic U 11.04 trash not working, can't find my trash dir

  - by Bruce Salem

  I did an upgrade from U 10.10 to U 11.04. I can't upgrade further because Upgrade Manager says that there are unsupported packages. How do I find them? A more immediate problem is that trash stopped working even though "/.share/local/Trash is getting files removed by the file manager. The trash icon on the lower panel fails after having done the upgrade from Gnome 2 to Unity and using Gnome Classic, says "No Such File or Directory". File Operations says it is looking at "/". How do I reconfigure the trash icon to use my local trash dir? The trash dir is there, has the right permissons, I can "rm" the dir tree there, and recreate it by moving files to the trash from the file manager.

  In my office I've Ubuntu 8.10 desktop installed and it's running for a long time.

• How to build a great relationship with your colleagues

How will you get along with them? What if they don’t like you? Have you ever felt you’re „the new guy” and your colleagues have already their own way of talking one to each other, their own jokes? It’s a common feeling and can actually become stressful. I am Norbert, Middleware Presales Intern in Hungary and I’ve been working within Oracle for only 1 month. Joining such a big company has been a challenge from many perspectives. One of them was adapting with the environment and getting to know all my colleagues. You know it’s quite difficult to introduce yourself, to try to liaise with them and find some common topics, so I felt very lucky and comfortable when my manager introduced me to all of my colleagues. It was easier to accommodate and we basically we had a starting point for our discussions. We started to talk about what my position means, for how many years they’ve been within Oracle, other Oracle related topics, but also more personal stuff like what they do after work. Having this opportunity of talking with all of them helped me introduce myself in a proper way and actually I told them many things about myself. Networking wasn’t my best skill, but these first days were really helpful from a network point of view. What else can you do to get along with your colleagues? One second thing I consider as being really helpful in networking is asking work-related questions. For instance, when you don’t know how to do something or don’t understand it, asking one of your colleagues will also help you to make a connection with him and you could easily continue the discussion with some other topics which are more personal. It’s a very effective strategy and in a company like Oracle people are very willing to help you with your tasks and perform at a high level. If you see your colleagues going to lunch, you should join them. It will help you become part of their community, finding out what’s new in their lives, you’ll, step-by-step, take part in their conversations and be up to date with the hot topics they talk about. One other opportunity of becoming part of your colleagues’ community are the internal events. Subscribing to the local free time activities mailing list is very useful for finding out information about when they’re going out and have a drink or attending all sorts of events. For instance, this is how I’ve found out about a party within Oracle that most of the employees here attend. It’s a wonderful opportunity for chatting and make a stronger connection to some of them. How important is attending these events? Think about how much time you spend at work. You’d like to enjoy your work and the environment, so getting along with your colleagues is a nice thing to have. I recently attended a corporate party whose purpose was to facilitate the interaction and communication between employees. It was a real success and we had a lot of fun, especially because it was a costume party.  All the fancy dresses and funny clothes we wore made the atmosphere really enjoyable. It was easy to liaise with colleague with whom I had never interacted with before. There was a friendly spirit among us, chatting about personal stuff and about various pleasant things. Working in an international company is not an easy thing because you interact with many people and they have different styles, but all these opportunities of informal interaction are a good way to adapt to the new working environment.

• Firefox profile issue

  Is there any limit in the number of firefox profiles that can be created? My issue is I am currently doing selenium webdriver automation in linux for a device. There are 50 devices of same kind and framework will pickup a device depending on availability. I need to by pass unsigned ssl pages. I am using firefox 14. I have implemented following but it is not consistent. everytime a device is chosen adds cer of device to the cert file in firefox profile but I am getting sec_error_bad_signature very frequently. So I started recreating cert [delete and create if by opening firefox] file for every run. Now this is posing a problem if multiple devices are run at the same time.

• Good PHP BOOKS for starters!

  - by Goma

  I started reading some PHP books. Most of them in their introduction say that this book , unlike other books, it follows a good habits and practices. Now, I do not know which book tells the truth, and which writer is the most experienced in PHP. These are the books that I had a quick look to their first chapter: PHP and MySQL Web Development (Developer's Library) by Luke Welling and Laura Thomson. Build Your Own Database Driven Web Site Using PHP & MySQL by Kevin Yank. PHP and MySQL for Dummies by Janet Valade. Now, it's your time to advise me and tell me about the excellent one that follows best practices, please give an advice from your experience. (It could be any other book!). Regards,

• What are the best social places for programmers to interact?

  - by Chevex

  I know this is not really the right place for this type of question, but I figure it will get me started and hopefully won't be closed right off the bat. I love the programming industry a lot, but I don't have many colleagues that aren't introverted and/or anti-social, or self-centered. What are some good places online to find programming friends that I could share my adventures with? I love stack overflow but it is more technical and doesn't really allow you to put up a personal project just for people to see and critique. Any suggestions? A good forum would be great! The only ones I can find are usually full of inexperienced people who just "want" to be a programmer. I'm looking more for a place who's members are already programmers discussing programming topics.

• Windows 8 fresh install and 12.10 dual boot

  - by Sir Linuxalot

  I have a question concerning Windows 8 and dual booting with Ubuntu 12.10. I've researched answers here, but haven't seen a question that resembles mine exactly: Ubuntu install and dual Boot with Windows 8 UEFI UEFI hardware and dual booting with windows Ubuntu 12.10 wont boot Specifically, I'm pondering installing a fresh install of Windows 8 (for game purposes), and a fresh install of 12.10 and dual booting them. I'm not sure if UEFI is hardware specific or software specific, and I'm worried if I try to implement the dual boot I'm going to run into UEFI issues and have to go through the grief of getting things up and running by following a long and tedious procedure. Can I, starting with Windows 8, then install 12.10 without too much hassle? My current hardware config is: Microstar Motherboard 7514 with an Intel Core 2 Duo processor. The drive I'm thinking of using is a Western Digital TB drive, new out of the box. As always, any help would be appreciated. Thanks.

• game performance

  - by iQue

  I'm making a game for android, and earlier today I was trying to add some cool stuff to my game. The problem is this thing needs like 5 timers. I build my timers like this: timer += deltaTime; if(timer >= 2.0f){ doStuff; timer -= 2.0f; } // this timers gets stuff done every 2 secs Will having to many timers like this, getting checked every frame, screw up my games performance? The effect I wanted to add was a crosshair every 2 sec, then remove it after 2 sec and do a timed animation. So an array of crosshairs dependent on a bunch of timers to be exact. This caused my game to shut down when used, so thats why Im wondering if using that many timers causes my game to flip out.

  TypeScript looks like a great start to evolving javascript.  I am going to start playing with it seeing what it is like.  This is the post I will update will all the resources I've found. Welcome to TypeScript - The TypeScript Language has an offical site, and this is it. This site does a nice job of giving the key information about the language and its uses, as well as highlighting that it is an open source project, which is cross platform. TypeScript is still causing quite a buzz in the community, here are some more of peoples initial impressions: Introducing TypeScript - Rob Eisenberg Why does TypeScript have to be the answer to anything? - Scott Hanselman TypeScript (or the obligatory post about it) - Shawn Wildermuth TypeScript project in Visual Studio 2012 - Linvi Microsoft TypeScript : A quick introduction and A Love Affair Begins here. - Anoop Madhusudanan Microsoft TypeScript : A Typed Superset of JavaScript & Using TypeScript in ASP.NET MVC Projects - Shiju Varghese Hello TypeScript - Getting Started - Sumit Maitra

• Pre-built Oracle VirtualBox Images

  - by james.bayer

  I’m thrilled to see that Justin Kestelyn has a post that pre-built Oracle VirtualBox images are now available on OTN.  There are VMs for various Oracle software stacks including one for Database, one for Java with Glassfish, and one for SOA and BPM products that includes WebLogic Server. This is just one example of the synergy of a combined Oracle and Sun delivering improvements for customers.  These VMs make it even more straight-forward to get started with Oracle software in a development environment without having to worry about initial software installation and configuration. I’ve been a bit quiet lately on the blogging front, but I’m currently working on another area leveraging the best of Oracle and Sun.  Oracle is uniquely positioned to deliver engineered systems that optimize the entire stack of software and hardware.  You’ve probably seen the announcements about Exalogic and I’m excited about the potential to deliver major advancements for middleware.  More to come…
