• Can not connect to wireless on 12.04 with Intel WiFi Link 5100

  - by WiData

  I am having problem in connecting to wifi. I have dual boot (Windows 7 and Ubuntu 12.04) on my Dell Studio 15. I upgraded to 12.04 quite some time ago (at least one month) from 11.10. Everything was working fine till yesterday. Since yesterday I can see the list of available Wifi connection but does not connect to any or if connects (after hours of trying) then disconnects after few minutes. My wifi interface is Intel WiFi Link 5100 AGN. However the problem is on both Windows and Ubuntu. Here are outputs of some commands which may be useful for those interested in helping: ~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:22:19:fa:65:bb UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:794 errors:0 dropped:0 overruns:0 frame:0 TX packets:794 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:56280 (56.2 KB) TX bytes:56280 (56.2 KB) wlan0 Link encap:Ethernet HWaddr 00:22:fb:d2:fc:ce UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:239 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:53603 (53.6 KB) Here is the output for the command sudo lshw -C network *-network description: Wireless interface product: WiFi Link 5100 vendor: Intel Corporation physical id: 0 bus info: pci@0000:04:00.0 logical name: wlan0 version: 00 serial: 00:22:fb:d2:fc:ce width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.2.0-48-generic-pae firmware=8.83.5.1 build 33692 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn resources: irq:47 memory:f8000000-f8001fff My kernel version is kernel version 3.2.0-48-generic-pae I also checked this post which was helpful.

• Environment naming standards in software development?

  - by Marcus_33

  My project is currently suffering from environment naming issues. Different people have different assumptions as to what environments should be named or what the names designate, and it's causing confusion when discussing them. I've done a bit of research and I haven't found any standards out there. The terms include "Local", "Sand", "Dev", "Test", "User", "QA", "Staging" and "Prod" (plus a few more that different people have asked about) I'm not looking for just opinions, though if there's one out there that "everyone" has I'll take it - I'm trying to find definitions advanced by some sort of authority, even if it's unofficial. Here's the environments we currently use: Environment on the developer's PC Shared Environment where developers directly upload code to self-test Shared Environment where standards and functionality are tested by QA people Shared Environment where completed and QA-checked code is approved by project requesters Environment that mirrors the final environment as a final check and to prepare for deployment Final Environment where code is in use I know what I'd call them, but is there some sort of standard on this? Thanks in advance.

• How to explain to a layperson the variance in programmer rates?

  - by Matt McCormick

  I recently talked to a guy that is looking for developers to build a product idea. He mentioned he has received interest from people but the rates have varied from $20-120/hr. This project he estimates should take 3-6 months and since he is non-technical, he is confused why there can be so much variance. I understand how I would choose someone but I am a developer and can gauge other people's work. How can I explain to him (in a non-biased way, if possible, as I will apply as well) about the variance in rates? Is there any good analogy that would help?

• Why are part-time jobs in programming an anomality?

  - by Mikle

  I've recently quit my full time developing job at mega-corp, and I decided that I'll look for a part time job. Since then I've talked to half a dozen potential employers, and every one of them had the same reaction when I said the magic words "part-time" - they all closed up and became suspicious. Now, I understand that it might just be me, so as control I asked every one of them what if I were willing to work full time, and they all said I would probably get an offer. My question is two fold: Why, as an employer, would you give up a competent, even great, developer, simply because he wants to work 3 days a week and not 5? How do I sell the story of part time job better? I usually just list my reasons which are that I prefer that balance currently in my life and that I want to work on my own projects, but it leaves them even more suspicious - am I going to start something myself and quit? Am I just lazy?

• Project planning and customer tracking system

  - by Daniel Hollands

  First off, sorry if this is the wrong 'stack' site, but it seemed like a good place to start. I'm happy to report that my services as a web developer are starting to be in quite a lot of demand, and I have a few existing and potentially new customers all lining up - but I'm finding it very hard to keep track of everything. What I'm hoping for is some (preferably web-based) system which I can use to keep track of who my customers are, the various projects that I've got going on for them, and (if possible) the individual sub-tasks that make up each project. What would be even better is if the relevant customer was able to log into the site, and see the process of their projects. I do hope you know what I'm talking about, and that you'll be able to offer some suggestions of either web-base sites that offer something along these lines, or of some open source solution or something like that? Thank you

• ASP.NET MVC ....or.... PHP, Python, Ruby, Java...?

  - by Muaz Khan

  I’m using ASP.NET MVC in C# and jQuery as well as Ajax. A lot of other web technologies confuse me: PHP, Python, Ruby, Java (or C++) etc. What is your opinion about ASP.NET MVC? Should I choose something else? Today, everyone says, “PHP” is worldly used language..!! And that’s true!!! I’m confused, much confused about my future career. I’m worried I’m not going in right direction! Or for making my future brighter, whether I should choose something else other than ASP.NET MVC and C#. And what would that something else be? I want to be a web developer that can do everything with web (and for web). I’m worried if I’m wasting my time with ASP.NET MVC!!!

• Support / Maintenance documentation for development team

  - by benwebdev

  Hi, I'm working in the Development dept (around 40 developers) for a large E-Commerce company. We've grown quickly but have not evolved very well in the field of documenting our work. We work with an Agile / Scrum-like methodology with our development and testing but documentation seems to be neglected. We need to be able to make documentation that would aid a developer who hasnt worked on our project before or was new to the company. We also have to create more high level information for our support department to explain any extra config settings and fixes of known issues that may arise, if any. Currently we put this in a badly put together wiki, based on an old Sharepoint / TFS site. Can anyone suggest some ideal links or advice on improving the documentation standard? What works in other companies? Has anyone got avice on developing documentation as part of an agile process? Many thanks, ben

• managing information/functionality on shared common project classes

  - by ilansch

  In my company, we have a common solution the contains common projects (2 projects so far, one for .net 3.5 and one for .net 4.5). My main problem is that during time, a lot of code is added, for example hosting a process as windows service is a class called ServiceManagement, But no one but the developer knows it, and if someone wants to use this shared class, he does not know it exist. So i am looking for a way to document and manage all the classes with tags, a 3rd party util/web util, that i can search for tags and maybe find common classes that i can use (if we keep all our code well-documented). Does anyone familiar with sort of tools ?

• SQL SERVER – A Brief Note on SET TEXTSIZE

  - by pinaldave

  Here is a small conversation I received. I thought though an old topic, indeed a thought provoking for the moment. Question: Is there any difference between LEFT function and SET TEXTSIZE? I really like this small but interesting question. The question does not specify the difference between usage or performance. Anyway we will quickly take a look at how TEXTSIZE works. You can run the following script to see how LEFT and SET TEXTSIZE works. USE TempDB GO -- Create TestTable CREATE TABLE MyTable (ID INT, MyText VARCHAR(MAX)) GO INSERT MyTable (ID, MyText) VALUES(1, REPLICATE('1234567890', 100)) GO -- Select Data SELECT ID, MyText FROM MyTable GO -- Using Left SELECT ID, LEFT(MyText, 10) MyText FROM MyTable GO -- Set TextSize SET TEXTSIZE 10; SELECT ID, MyText FROM MyTable; SET TEXTSIZE 2147483647 GO -- Clean up DROP TABLE MyTable GO Now let us see the usage result which we receive from both of the example. If you are going to ask what you should do – I really do not know. I can tell you where I will use either of the same. LEFT seems to be easy to use but again if you like to do extra work related to SET TEXTSIZE go for it. Here is how I will use SET TEXTSIZE. If I am selecting data from in my SSMS for testing or any other non production related work from a large table which has lots of columns with varchar data, I will consider using this statement to reduce the amount of the data which is retrieved in the result set. In simple word, for testing purpose I will use it. On the production server, there should be a specific reason to use the same. Here is my candid opinion – I do not think they can be directly comparable even though both of them give the exact same result. LEFT is applicable only on the column of a single SELECT statement. where it is used but it SET TEXTSIZE applies to all the columns in the SELECT and follow up SELECT statements till the SET TEXTSIZE is not modified again in the session. Uncomparable! I hope this sample example gives you idea how to use SET TEXTSIZE in your daily use. I would like to know your opinion about how and when do you use this feature. Please leave a comment. Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Java EE and GlassFish Server Roadmap Update

  - by John Clingan

  2013 has been a stellar year for both the Java EE and GlassFish Server communities. On June 12, Oracle and its partners announced the release of Java EE 7, which delivers on three major themes – HTML5, developer productivity, and meeting enterprise demands. The online event attracted over 10,000 views in the first two days! During the online event, Oracle also announced the availability of GlassFish Server Open Source Edition 4, the world's first Java EE 7 compatible application server. The primary role of GlassFish Server Open Source Edition has been, and continues to be, driving adoption of the latest release of the Java Platform, Enterprise Edition. Oracle also announced the Java EE 7 SDK, which bundles GlassFish Server Open Source Edition 4, as a Java EE 7 learning aid. Last, Oracle publicly announced the Java EE 7 reference implementation based on GlassFish Server Open Source Edition 4. Java EE is a popular platform, as evidenced by the 20+ Java EE 6 compatible implementations available to choose from. After the launch of Java EE 7 and GlassFish Server Open Source Edition 4, we began planning the Java EE 8 roadmap, which was covered during the JavaOne Strategy Keynote. To summarize, there is a lot of interest in improving on HTML5 support, Cloud, and investigating NoSQL support. We received a lot of great feedback from the community and customers on what they would like to see in Java EE 8. As we approached JavaOne 2013, we started planning the GlassFish Server roadmap. What we announced at JavaOne was that GlassFish Server Open Source Edition 4.1 is scheduled for 2014. Here is an update to that roadmap. GlassFish Server Open Source Edition 4.1 is scheduled for 2014 We are planning updates as needed to GlassFish Server Open Source Edition, which is commercially unsupported As we head towards Java EE 8: The trunk will eventually transition to GlassFish Server Open Source Edition 5 as a Java EE 8 implementation The Java EE 8 Reference Implementation will be derived from GlassFish Server Open Source Edition 5. This replicates what has been done in past Java EE and GlassFish Server releases. Oracle will no longer release future major releases of Oracle GlassFish Server with commercial support – specifically Oracle GlassFish Server 4.x with commercial Java EE 7 support will not be released. Commercial Java EE 7 support will be provided from WebLogic Server. Oracle GlassFish Server will not be releasing a 4.x commercial version Expanding on that last bullet, new and existing Oracle GlassFish Server 2.1.x and 3.1.x commercial customers will continue to be supported according to the Oracle Lifetime Support Policy. Oracle recommends that existing commercial Oracle GlassFish Server customers begin planning to move to Oracle WebLogic Server, which is a natural technical and license migration path forward: Applications developed to Java EE standards can be deployed to both GlassFish Server and Oracle WebLogic Server GlassFish Server and Oracle WebLogic Server have implementation-specific deployment descriptor interoperability (here and here). GlassFish Server 3.x and Oracle WebLogic Server share quite a bit of code, so there are quite a bit of configuration and (extended) feature similarities. Shared code includes JPA, JAX-RS, WebSockets (pre JSR 356 in both cases), CDI, Bean Validation, JAX-WS, JAXB, and WS-AT. Both Oracle GlassFish Server 3.x and Oracle WebLogic Server 12c support Oracle Access Manager, Oracle Coherence, Oracle Directory Server, Oracle Virtual Directory, Oracle Database, Oracle Enterprise Manager and are entitled to support for the underlying Oracle JDK. To summarize, Oracle is committed to the future of Java EE.  Java EE 7 has been released and planning for Java EE 8 has begun. GlassFish Server Open Source Edition continues to be the strategic foundation for Java EE reference implementation going forward. And for developers, updates will be delivered as needed to continue to deliver a great developer experience for GlassFish Server Open Source Edition. We are planning for GlassFish Server Open Source Edition 5 as the foundation for the Java EE 8 reference implementation, as well as bundling GlassFish Server Open Source Edition 5 in a Java EE 8 SDK, which is the most popular distribution of GlassFish. This will allow GlassFish releases to be more focused on the Java EE platform and community-driven requirements. We continue to encourage community contributions, bug reports, participation on the GlassFish forum, etc. Going forward, Oracle WebLogic Server will be the single strategic commercially supported application server from Oracle. Disclaimer: The preceding is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract.It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions.

• How do you approach database design?

  - by bron

  I am primarily a web developer and I have a couple of personal projects which I want to kick off. One thing that is bugging me is database design. I have gone through in school db normalization and stuff like that but it has been a couple of years ago and I have never had experience with relational database design except for school. So how you do you approach database from a web app perspective? How do you begin and what do you look out for? What are flags for caution?

• "sr0" I/O read boot error in Xubuntu 12.10

  - by Entropicurity

  Just recently upgraded Xubuntu 12.10 after having installed 12.04 originally. Ever since that happened, any time I inserted a disk into my DVD/CD reader/writer I would end up getting a number of error messages from my DVD player/Audio player softer, typically with any of them either crashing or returning a GStreamer backend error. So doing some research I tried to mount it manually, and it typically returned the error messages you'll see below: (using the dmesg | grep "sr0" command) [17545.435584] end_request: I/O error, dev sr0, sector 0 [17545.492968] sr 3:0:0:0: >[sr0] [17545.492981] sr 3:0:0:0: >[sr0] [17545.492992] sr 3:0:0:0: >[sr0] [17545.493003] sr 3:0:0:0: >[sr0] CDB: [17545.493020] end_request: I/O error, dev sr0, sector 0 [17545.493058] EXT3-fs (sr0): error: unable to read superblock [17545.553224] sr 3:0:0:0: >[sr0] [17545.553237] sr 3:0:0:0: >[sr0] [17545.553247] sr 3:0:0:0: >[sr0] [17545.553258] sr 3:0:0:0: >[sr0] CDB: [17545.553275] end_request: I/O error, dev sr0, sector 0 [17545.553312] EXT4-fs (sr0): unable to read superblock [17545.611482] sr 3:0:0:0: >[sr0] [17545.611494] sr 3:0:0:0: >[sr0] [17545.611504] sr 3:0:0:0: >[sr0] [17545.611514] sr 3:0:0:0: >[sr0] CDB: [17545.611531] end_request: I/O error, dev sr0, sector 0 [17545.611568] FAT-fs (sr0): unable to read boot sector When I grepped this, the number of error messages just seemed to spill all over the screen, and typically all revolve around the I/O error. I then went into VLC and tried to run the stuff through there, but for some reason it won't read with the default devices. Instead I have to manually input sr0 into each of the /dev/ references and it will play just fine, until I exit out of the program, at which point I have to re-input everything. I have already installed all the media dependencies, both open source and restricted, through the software center. I just found this strange, as out of the box 12.04 there wasn't any problem what so ever. At this point, it could be that all my audio CD's are not in a format that is familiar with the OS (I've read in some places that EXTF4 has issues with this) but I don't see how that could be a problem when the above error messages even tested to see if it is EXT3 as well? I've tried my best to troubleshoot this up till now using existing topics, but it seems that this is a regular problem with a multitude of varying factors that incorporate into it, including but not limited to read/write problems with the format of the CD and right protection. Is there something integral that I am missing?

• junior / professional / senior categorization

  - by oozoo

  Hey guys, is it just me or is the categorization of developer levels highly subjective? I get the feeling that every company tries to hire experienced developers as juniors because they don't know $technology. For example my own career: I switched technologies a couple of times, while sticking to java as a programming language. For example I first worked for 3 years using JavaSE technologies, the next company I worked for hired me as junior because I didn't have JavaEE experience - while still selling me as professional level to customers (I work in consulting). The next company hired me again as junior because I didn't have SAP experience - they mostly work with SAP Java technologies which is definitely a niche. Still, they are selling all their technology consultants for exactly the same rate while paying them significantly different wages. Now when switching jobs again I feel like this whole thing is going to start all over again because I don't have Spring experience or Oracle knowledge. tl;dr = is my observation totally off base that companies are just using these categorizations as means to keep down wages?

• How Easy is it to Code In-Built Videos?

  - by Alan Parker

  First time poster so please don't bite my head off. Basically, I'm having a site built for me and I don't really know anything about coding but I'm not too sure if I trust my web developer. I asked him recently about adding a feature where I could display built-in videos like the following page - http://www.ejot.co.uk/buildingfasteners.odl and he quoted me quite a high amount for it. I just wanted to double check with you guys whether this is a difficult feature to add in and whether it justifies a reasonable amount of money on top of what I'm already paying him. Thanks in advance for your help, Alan

• Object-Oriented Operating System

  - by nmagerko

  As I thought about writing an operating system, I came across a point that I really couldn't figure out on my own: Can an operating system truly be written in an Object-Oriented Programming (OOP) Language? Being that these types of languages do not allow for direct accessing of memory, wouldn't this make it impossible for a developer to write an entire operating system using only an OOP Language? Take, for example, the Android Operating System that runs many phones and some tablets in use around the world. I believe that this operating system uses only Java, an Object-Oriented language. In Java, I have been unsuccessful in trying to point at and manipulate a specific memory address that the run-time environment (JRE) has not assigned to my program implicitly. In C, C++, and other non-OOP languages, I can do this in a few lines. So this makes me question whether or not an operating system can be written in an OOP, especially Java. Any counterexamples or other information is appreciated.

• An update on using Rosetta Stone: Studio now isn't very useful and is not great value as an add-on option

  - by Greg Low

  I had a surprisingly large number of responses from my previous posting about learning Chinese. An update for those considering Rosetta Stone (www.rosettastone.com) for Chinese, Spanish or any other language that they offer:I had to renew my "Studio" subscription today and it's now a much worse deal than it was.It's now $75 for 6 months for Studio sessions. Online classes used to be 45 mins. Recently they reduced them to 20 mins. Given how often people have connection issues, etc. that 20 mins can disappear very quickly.They've also reduced the number you can attend. You used to be able to have 2 scheduled at any point in time. Now they limit you to 2 "group sessions" per month during the period. (You can pay for additional private sessions). The combination of these two changes now makes it much less useful. Two x 20 min sessions per month is an almost meaningless amount of practice. They also now automatically change you to auto-renew when you subscribe. They tell you where to remove this auto-renewal but the first 4 or 5 times that I went into that screen, no such option appeared. Later, an option did appear and I used it.Overall, things just aren't what they used to be at Rosetta Stone. It's now pretty hard to recommend the Studio option where it was a no-brainer before.FURTHER UPDATE: <sigh>Even after I renewed, I could not even connect to their "new" service. Although the system processed the renewal, it still tells me it's expired. My online chat person "Siva S" tells me that the problem is that I've purchased all 5 levels of the program. I can't wait till they explain to me how making an extra purchase from them stops me from logging on. Siva told me that they had "renewed" the program. I'd have to speak to Customer Care; they aren't available and then disconnected himself. Impressive (not).Their website is now full of issues too. It insists that my billing address is in the USA, even though it pretends to accept changes to it.Overall, it's gone from something that could be recommended (with some limitations) to now being an app to avoid. That's a pity as I liked much of it before.

• How-to hide the close icon for task flows opened in dialogs

However, no event is sent to the calling page to handle the close case. To avoid users closing the dialog without the calling application to be notified in a return listener, the close icon shown in the opened dialog can be hidden using ADF Faces skinning.

To only hide the close icon from dialogs opened by a bounded task flow call activity, the ADF Faces component styleClass property can be used. The af:panelWindow component shown below has a "withCloseWindow" style class property name defined. This name is referenced in the following skin selector, ensuring that the close icon is displayed af|panelWindow.withCloseIcon::close-icon-style{ display:block; } In summary, to hide the close icon shown for bounded task flows that are launched in inline popup dialogs, the default display behavior of the close icon of the af:panelWindow needs to be reversed. Instead to always display the close icon, the close icon is always hidden, using the first skin selector. To show the disclosed icon in other usages of the af:panelWindow component, the component is flagged with a styleClass property value as shown below <af:popup id="p1">   <af:panelWindow id="pw1" contentWidth="300" contentHeight="300"                                 styleClass="withCloseIcon"/> </af:popup> The "withCloseIcon" value is referenced in the second skin definition af|panelWindow.withCloseIcon::close-icon-style{ display:block; } The complete entry of the skin CSS file looks as shown below: af|panelWindow::close-icon-style{ display:none; } af|panelWindow.withCloseIcon::close-icon-style{ display:block; }

• Checking for cross-site scripting vulnerabilities in Perl web applications

  - by David Scholefield

  I'm putting together some notes for a dev team on how to write secure Perl code - especially taking into account the current OWASP top 10 web application vulnerabilities. For cross-site scripting I've included information on ensuring that all output to the browser is checked and escaped where necessary, but I'm looking for more automated mechanisms that would mean a developer doesn't have to think about every output statement and, potentially, miss one. Perl's 'taint' function sounds like it should be a help because it distrusts all user input, but it doesn't complain on tainted data being output to the browser. Apart from checking all output statements individually (probably by calling a generic sanitizing function) does anyone have any ideas on how Perl can help with this with existing libraries or techniques?

• Why wearing Jeans is considered unprofessional?

  - by Gopinath

  When I started my career 9 years ago I use to wear casual wear to office – Jeans & T-Shirts all the 5 days. The environment at workplace during those days encouraged me to be casual and many of my colleagues use to come in Jeans. We just started our career those days it was perfectly fine to be in casual. As I grow up in the ladder, I started feeling the discomfort of wearing Jeans at work. During clients visits, senior managers meetings and consultations I was an odd man in the crowd as the rest of them are in formals. In order to be one among the professionals I’m forced change my dressing style and start wearing formals. But  the question of “Why wearing jeans to workplace is considered as unprofessional?” use in linger in my mind till today. I got the answer to my question from a discussion thread on Quora When they were invented, jeans were associated with blue-collar work. They were meant to get muddy and gross and take lots of abuse without falling apart, even if you wore the same pair every day. The people who bought them were the ones whose lives required durable clothing. And another commenter says… A professional image is critical to cementing business relationships, and part of that is, for right or wrong, how you dress. Jeans are typically associated with "kicking back", relaxation, leisure, informality,  and even a slightly rebellious flavor. The style and condition of the jeans are a consideration, as we often wear jeans into advanced states of being worn down, with tearing, etc.. that we generally do not do with other clothing items. I agree with this theory even though it may be centuries old. If you want to look like a professional and treated like a professional it’s better to be dress up in formals. These days I make a point to be in formals at workplace. Not everyone is Steve Jobs to wear a Jean & Turtle Neck T-shirt  right? CC Image credit flickr/exey

• 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,

• Do the best developers look for a better job, or a better job finds them?

  - by Vasil Remeniuk

  As an example, one of the JavaPosse (popular Java podcast) hosts, Tor Norbey, has recently moved from Oracle to Google, and I'm more that sure that he has been lured (he definitely has not been sending his CV to Google). The rumor has it that 'high-level' developers are never hired through the job-sites. So, (given that you're a good developer) when you what to hold an appealing position in the company that interests you, and invest a lot of time into increasing your online-presence and self-branding blogging, twitting, contributing to opensource, actively participating in community sites (e.g., Stackoverflow), should you send your CVs here and there or just wait for proposals?

• Community Branching

  - by Dane Morgridge

  As some may have noticed, I have taken a liking to Ruby (and Rails in particular) quite a bit recently. This last weekend I spoke at the NYC Code Camp on a comparison of ASP.NET and Rails as well as an intro to Entity Framework talk.  I am speaking at RubyNation in April and have submitted to other ruby conferences around the area and I am also doing a Rails and MongoDB talk at the Philly Code Camp in April. Before you start to think this is my "I'm leaving .NET post", which it isn't so I need to clarify. I am not, nor do I intend to any time in the near future plan on abandoning .NET.  I am simply branching out into another community based on a development technology that I very much enjoy.  If you look at my twitter bio, you will see that I am into Entity Framework, Ruby on Rails, C++ and ASP.NET MVC, and not necessarily in that order.  I know you're probably thinking to your self that I am crazy, which is probably true on several levels (especially the C++ part). I was actually crazy enough at the NYC Code Camp to show up wearing a Linux t-shirt, presenting with my MacBook Pro on Entity Framework, ASP.NET MVC and Rails. (I did get pelted in the head with candy by Rachel Appel for it though) At all of the code camps I am submitting to this year, i will be submitting sessions on likely all four topics, and some sessions will be a combination of 2 or more.  For example, my "ASP.NET MVC: A Gateway To Rails?" talk touches ASP.NET MVC, Entity Framework Code First and Rails. Simply put (and I talk about this in my MVC & Rails talk) is that learning and using Rails has made me a better ASP.NET MVC developer. Just one example of this is helper methods.  When I started working with ASP.NET MVC, I didn't really want to use helpers and preferred to just use standard html tags, especially where links were concerned.  It was just me being stubborn and not really seeing all of the benefit of the helpers.  To my defense, coming from WebForms, I wanted to be as bare metal as possible and it seemed at first like a lot of the helpers were an unnecessary abstraction. I took my first look at Rails back in v1 and didn't spend very much time with it so I dismissed it and went on my merry ASP.NET WebForms way.  Then I picked up ASP.NET MVC and grasped the MVC pattern itself much better. After this, I took another look at Rails and everything made sense.  I decided then to learn Rails. (I think it is important for developers to learn new languages and platforms regularly so it was a natural progression for me) I wanted to learn it the right way, so when I dug into code, everyone used helpers everywhere for pretty much everything possible. I took some time to dig in and found out how helpful they were and subsequently realized how awesome they were in ASP.NET MVC also and started using them. In short, I love Rails (and Ruby in general).  I also love ASP.NET MVC and Entity Framework and yes I still love C++.  I have varying degrees of love for them individually at any given moment and it is likely to shift based on the current project I am working on.  I know you're thinking it so before you ask the question. "Which do I use when?", I'm going to give the standard developer answer of: It depends.  There are a lot of factors that I am not going to even go into that would go into a decision.  The most basic question I would ask though is,  does this project depend on .NET?  If it does, then I'd say that ASP.NET MVC is probably going to be the more logical choice and I am going to leave it at that.  I am working on projects right now in both technologies and I don't see that changing anytime soon (one project even uses both). With all that being said, you'll find me at code camps, conferences and user groups presenting on .NET, Ruby or both, writing about .NET and Ruby and I will likely be blogging on both in the future.  I know of others that have successfully branched out to other communities and with any luck I'll be successful at it too. On a (sorta) side note, I read a post by Justin Etheredge the other day that pretty much sums up my feelings about Ruby as a language.  I highly recommend checking it out: What Is So Great About Ruby?

• As a programmer how do I plan to learn new things in my spare time

  - by priyank patel

  I am a Asp.Net/C# developer, I develop few projects in my spare time. I try to utilize my time as much as I can. I have been working for past 7 months. Suddenly these days I am a bit worried about learning the new stuff that is there for me as a programmer. I develop in my spare time so I don't get enough time to read books or blogs. So my question to some of you guys is how should I plan to learn new things, should I at least dedicate two-three evenings for new stuff, maybe ebooks while travelling is a good option too. How do you people plan to learn,should I also start to develop with whatever I learnt? As far as learning is concerned, should I just pick up the basics and then implement it or I should seek deeper understanding of the subject?

• Making your ASP.NET/HTML Websites Indic aware &ndash; accepting Tamil, Telugu, Kannada, Hindi and ot

  - by Harish Ranganathan

  Its been a month since I wrote my last post.  Much of work has been happening around planning for Tech Ed India, the upcoming Virtual TechDays this week as well as our Developer content at the Great Indian Developer Summit 2010.  Its going to be one exciting period starting this week and I am glad I would be able to meet a lot of folks who have written to me personally that they would like to catch up at Tech Ed India. For now, I had a chance to meet the Microsoft India Development Centre team that worked on the Microsoft Indic Language Input Tool (erstwhile Akshara). The team updated me that they have also released the scripts  so that the Indic input feature can be encapsulated into your own websites.  For example, if you are having a web page where you collect user information, you can pretty much make your site indic aware i.e. accept inputs in Tamil, Telugu, Kannada, Hindi etc.,  All you would need to include would be a bunch of scripts onto your web pages and you are ready to make it, like I said, “indic aware” I have built a sample web page that accepts First Name, Last Name, Address and an additional field.  When it comes to accepting indic, sometimes, you may want to avoid the indic input in certain fields and accept it in English.  You can specify the MicrosoftILITWebAttach="false" attribute to the Text Boxes and Text Areas (TextMode=”Multiline” in ASP.NET) so that the particular field automatically switches over to English input.  Similarly, the moment you specify that the TextMode=”Password” to make it as a password field, it automatically ignores all indic recognition and shows the masked dots for the words entered. Note that, this is, when we are going for the Opt-out mode, where we are specifying that by default all the input controls would need indic awareness and we would specify for those controls where it is not required.  The other mode is Opt-in mode where you would need to add a different property to the script definition i.e. attachMode=”optin” .  When we do this, we need to explicitly add the MicrosoftILITWebAttach="true" attribute for every control where we need indic input. I have created a sample web page which accepts First Name, Last Name, Address and an additional input field to demonstrate the “Opt-out”.   You can copy paste this into any of your web pages to check it <form id="form1" runat="server">     <!-- Microsoft Indic Language Input Tool embed code --> <input type="hidden" id="MicrosoftILITWebEmbedInfo" attachMode="optout" value="" /> <script type="text/javascript" src="http://ilit.microsoft.com/bookmarklet/script/Tamil.js" defer="defer"></script>     <div>     <h2>         Welcome to the Registration Page     </h2>     <p>         First Name: <asp:TextBox runat="server" ID="txtFirstName" />         <br />         <br />         Last Name: <asp:TextBox runat="server" ID="txtLastName" />         <br />         <br />         Password:         <asp:TextBox runat="server" ID="txtPassword" TextMode="Password" />         <br />         <br />         Address: <asp:TextBox runat="server" ID="txtAddress" TextMode="MultiLine" Height="100" Width="200" />         <br />         <br />         English Text: <asp:TextBox ID="txtEnglishText" runat="server" MicrosoftILITWebAttach="false" />     </p>     <p>         <!-- Microsoft Indic Language Input Tool attribution image link --> <a style="text-decoration: none" href="http://go.microsoft.com/fwlink/?LinkID=184205&clcid=0x409"><img style="border: 0px" alt="Transliteration by Microsoft" src="http://ilit.microsoft.com/bookmarklet/images/attribution.png"></a>     </p>     </div>     </form> If you note the code snippet above, I have included the scripts in the top with the attachMode set to “optout” and for the last TextBox, I have mentioned the MicrosoftILITWebAttach="false” attribute to make it accept English input.   Additionally, you also need to add the “Microsoft Indic Language Input Tool attribution image” to your web page as a courtesy to the team that developed this feature.  It would basically add a image saying “Transliteration by Microsoft” similar to a Copy Right image.  You can see the screen shot below where I have typed it in Tamil.  In that you will notice that the password field behaves as expected and the last field accepts English Text.  You can also notice the icon that comes in the first textbox that indicates that, the field is going to accept indic text.   This sample is using Tamil, but you can pretty much do it for Hindi, Telugu, Kannada, Marathi, Bengali etc.,   The website for getting the Indic script and other instructions is http://specials.msn.co.in/ilit/WebEmbed.aspx?language=Tamil You can replace the querystring value “Tamil” to other languages as mentioned above to get the respective script. This also works for plain HTML based websites and doesn’t necessarily need you to use ASP.NET to achieve the functionality. Note that, this form is not completely localized.  This is transliterated.  You can add label controls for FirstName, LastName indication etc., and use the Visual Studio tools to localize and get those values from resource files.  In the resource files, you can enter the text in different languages to make this a truly localized page.  If you just want to download the Indic Tool Desktop version (that can be used for typing in Word, Excel, pretty much any input area), you can download it from http://specials.msn.co.in/ilit/  In the same page, there is also a web version where you can type and get text then and there if you dont want to install the desktop version. So, go ahead, download / use them in your websites and enjoy the power of Indic. Cheers !!!
