  • More FlipBoard Magazines: Azure, XAML, ASP.NET MVC & Web API

    - by dwahlin
    In a previous post I introduced two new FlipBoard magazines that I put together including The AngularJS Magazine and The JavaScript & HTML5 Magazine. FlipBoard magazines provide a great way to keep content organized using a magazine-style format as opposed to trudging through multiple unorganized bookmarks or boring pages full of links. I think they’re really fun to read through as well. Based on feedback and the surprising popularity of the first two magazines I’ve decided to create some additional magazines on topics I like such as The Azure Magazine, The XAML Magazine and The ASP.NET MVC & Web API Magazine. Click on a cover below to get to the magazines using your browser. To subscribe to a given magazine you’ll need to create a FlipBoard account (not required to read the magazines though) which requires an iOS or Android device (the Windows Phone 8 app is coming soon they say). If you have a post or article that you think would be a good fit for any of the magazines please tweet the link to @DanWahlin and I’ll add it to my queue to review. I plan to be pretty strict about keeping articles “on topic” and focused.   The Azure Magazine   The XAML Magazine   The ASP.NET MVC & Web API Magazine   The AngularJS Magazine   The JavaScript & HTML5 Magazine

  • Does software architect/designer require more skills and intellectual than software engineer (implementation)?

    - by Amumu
    So I heard the positions for designing software and writing spec for developers to implement are higher and getting paid more. I think many companies are using the Software Engineering title to depict the person to implement software, which means using tools and technologies to write the actual code. I know that in order to be a software architecture, one needs to be good at implementation in order to have an architectural overview of a system using a set of specific technologies. This is different than I thought of a Software Engineer. My thinking is similar to the standard of IEEE: A software engineer is an engineer who is capable of going from requirement analysis until the software is deployed, based on the SWEBOK (IEEE). Just look at the table of content. The IEEE even has the certificate for Software Engineering, since ABET (Accreditation Board for Engineering and Technology) seems to not have an official qualification test for Software Engineer (although IEEE is a member of ABET). The two certificates are CSDA and CSDP. I intend to take on these two examination in the future to be qualified as a software engineer, although I am already working as one (Junior position). On a side note on the issues of Software Engineer, you can read the dicussion here: Just a Programmer and Just a Software Engineer. The information of ABET does not accredit Software Engineer is in "Just a Software Engineer". On the other hand, why is Programmer/Softwar Engineer who writes code considered a low level position? Suppose if two people have equal skills after the same years of experience, one becomes a software architect and one keeps focus on implementation aspect of Software Engineering (of course he also has design skill to compose a system, since he's a software engineer as well, but maybe less than the specialized software architect), how comes work from Software Engineer is less complicated than the Software Architect? In order to write great code with turn design into reality, it requires far greater skill than just understanding a particular language and a framework. I don't think the ones who wrote and contributing Linux OS are lower level job and easier than conceptual design and writing spec. Can someone enlighten me?

  • Does it matter to you that a software is "available source" but not "open source"

    - by ccpod
    You probably know the list of open source licenses officially approved by the OSI. Most notably I guess would be the GPL, MIT, [insert your favorite license here]. I recently ran into a project which although was open source (the creator made all source code available), was not officially open source under one of those official licenses. It released the source, but made no promise to release the source in the future. It allowed modification suggestions, but made no promises to accept patches and disallowed external distribution of externally-patched versions. It allowed the use of the software in commercial or paid projects, but disallowed the sale of the software itself. I suppose it could be called "available source" not open source as we like to think of it. I can see why the management team of a company wouldn't want to do business with this software. They can't fork it, they can't sell it, they can't create their own version of the software and distribute it or sell it. But would it matter to you as part of a software engineering team who's just using this software? I can still get my work done with it, I can use it in a project for which I'm paid (but I can't sell the software itself, which I'm not in the business of doing anyway), and I can make changes to the code to make it behave differently for my needs (but I can't make those modifications public), and if I do want those modifications officially made available to others, the approval is up to the project itself and they choose whether to incorporate them in an official release or not. So we know that a company that wants to base its business on this "available source" software can't do that, but as someone from the software engineering team, would those differences matter to you or do they seem less relevant? Curious what others think of this.

  • Future direction for a developer who is expert in latest software technologies…

    - by Muaz Khan
    Hi everyone, If a (new-coming) developer that learns latest technologies as well as can develop amazing stuff with those technologies and did Bachelors in Arts (BA). So what ’ll be the future of this kind of developer? I meant did he can get good job without degree? I think (but it is the universal truth that) no one (org or company) permit these kind of developers to join them because degree is must for job!! I’m worried about why the world depends upon degree? Why degree is necessary for good job? If a developer has a good experience, why he cannot be able to get good job without degree? What is the future of developer that starts his life as a freelancer and learns everything himself with the help of online available resources? Why companies prerequisite the degree for a good job? A developer without degree can be expert than that who have a degree of MSC etc. Because in 3rd world countries especially Pakistan, a BSC level student taught VB6 and the MSC level student learns C/C++. The common student doesn’t know about latest innovative technologies and he think that the world is depending upon VB6 or C/C++. What is the comparison of that students with a developer that do Bachelors in Arts but know (and can do well with) latest technologies.

  • book about psychology of decision and psychology of human

    - by boos
    I'm a unix developer and i want to make career in project/people management as first step. I think sometimes is better to have good communication skill and in general more human skill to make career more fast. Almost in Italy, a lot of people made career development more fast for his human skill and not for his technical skill. Anyone have read some book about psychology to better manage how people and personality work and to exploit decision making situation in the right way? I have found some interesting book about people personality and psychology of decision, but i am in doubt about the usefulness about reading such book. anyone have some experience in this path ? Anyone have found useful to read similar book about how people work, to manage career development in a more fast way and handle people and decision in a more useful way? i have already read peopleware. The table of content of one of this book have: 1 - Judicment and decision 2 - Euristics and sistematics error 3 - Estimating probability and frequency prediction 4 - Risk and decision 5 - rappresentation and decision 6 - Memory, attention and decision. Etc. what do you think about ?

  • Why does my PowerBook display “Fixing recursive fault but reboot is needed!” and stop booting?

    - by Blacklight Shining
    I have an old PowerBook G4 that worked (more or less) fine with a previous installation of Ubuntu Desktop 12.04. A few days ago I decided to install Ubuntu Server instead, and got a copy of Ubuntu Server 12.10. The installation seemed to complete successfully, but now, whenever I try to boot the system, it simply halts at some point after I unlock the hard disk. There is a lot of text on the screen (which is normal for me during a boot, except now it's mostly errors and debug information), the last of which is this: [ 26.338228] Fixing recursive fault but reboot is needed! Pressing control command power to force a reboot yields exactly the same results. A search for the error message turned up many temporary solutions involving kernel parameters, but none of them have worked for me. I don't think I can remove the default set of parameters (which I think is quiet splash), but I can pass additional parameters on boot. I've tried booting on AC and battery power, as well as using these combinations of kernel parameters while on battery power: acpi=enable pci=noacpi pci=assign-busse acpi=ht acpi=off nomodeset nomodeset acpi=off Why am I getting this error and how can I fix it?

  • What makes a Software Craftsman?

    - by Liam McLennan
    At the end of my visit to 8th Light Justin Martin was kind enough to give me a ride to the train station; for my train back to O’Hare. Just before he left he asked me an interesting question which I then posted to twitter: Liam McLennan: . @JustinMartinM asked what I think is the most important attributes of craftsmen. I said, "desire to learn and humility". What's yours? 6:25 AM Apr 17th via TweetDeck several people replied with excellent contributions: Alex Hung: @liammclennan I think kaizen sums up craftmanship pretty well, which is almost same as yours Steve Bohlen: @alexhung @liammclennan those are both all about saying "knowing what you don't know and not being afraid to go learn it" (and I agree!) Matt Roman: @liammclennan @JustinMartinM a tempered compulsion for constant improvement, and an awareness of what needs improving. Justin Martin: @mattroman @liammclennan a faculty for asking challenging questions, and a persistence to battle through difficult obstacles barring growth I thought this was an interesting conversation, and I would love to see other people contribute their opinions. My observation is that Alex, Steve, Matt and I seem to have essentially the same answer in different words. It is also interesting to note (as Alex pointed out) that these definitions are very similar to Alt.NET and the lean concept of kaizen.

  • The Other "C" in CRM

    - by Brian Dayton
    Folks who know me know that I rarely, if ever, talk politics. And I never talk politicians. Having grown up in a household with one parent leaning left and the other leaning to the right it was the best way to keep the peace. This isn't about politics. It's about "constituents" and the need to improve the services and service levels for people--at the city, county, state/province, etc. level all the way up to national governments. As a citizen and tax payer it's also important to me that these services be provided at a reasonable cost. If there's a better and more efficient way to do something then it's my hope that a public sector organization takes advantage of technology the same way private sector companies do. Social services organizations have a complex job. They provide the services that people need, from healthcare and children's assistance to helping people find jobs. But many of these organizations are still managing these processes manually or outdated, home-grown applications that could have been written up to 30 years ago. A lot has changed in technology. On the (this is as political as I'm going to get) political front, stakeholders like you and me are expecting greater transparency on where and how funds are spent. I'll admit that most of the time, when I think about CRM systems, I think about my experience as a customer of my bank, utilities company or cable operator. But now that I'm older, have children and a house--I find myself interacting more and more with agencies and services organizations. My experiences are sometimes good and sometimes not so good. Along those lines, last week's announcement of Siebel CRM 8.2 for Public Sector caught my eye. You may not work in the public sector, but you are a constituent of some--actually a lot--of public sector organizations. I don't know which CRM systems city and county utilize but I'm going to start paying closer attention.

  • Should we enforce code style in our large codebase?

    - by eighttrackmind
    By "code style" I mean 2 things: Style, eg. // bad if(foo){ ... } // good if (foo) { ... } Conventions and idiomaticity, where two ways of writing the same thing are functionally equivalent, but one is more idiomatic. eg. // bad if (fooLib.equals(a, b)) { ... } // good if (a == b) { ... } I think it makes sense to use an auto-formatter to enforce #1 automatically. So my question is specifically about #2. I like to break things down into pros and cons, here's what I've come up with so far: Pros: Used by many large codebases (eg. Google, jQuery) Helps make it a bit easier to work on new areas of the codebase Helps make code more portable (this is not necessarily true) Code style is automatic once you get used to it Makes it easier to fast-decline pull requests Cons: Takes engineers’ and code reviewers’ time away from more important things (like developing features) Code should ideally be rewritten every 2-3 years anyway, so it’s more important to focus on getting the architecture right, and achieving high test coverage Adds strain to code reviews (eg. “don’t do it this way, I like this other way better”) Even if I’ve been using a code style for a while, I still sometime have to pause and think about how to write a line better Having an enforced, uniform code style makes it hard to experiment with potentially better styles Maintaining a style guide takes a lot of incremental effort Engineers rarely read through the style guide. More often, it's cited in code reviews And as a secondary question: we also have many smaller repositories - should the same code style be enforced there?

  • Part 2: Career development as a Software Developer without becoming a manager.

    - by albertpascual
    Seems like my previous post inspired by the work of Michael “Doc” Norton was a great success for the amount of emails I have received. Yet amazed how many people didn’t want to discuss their questions in the comments  sections. I would encourage people to be more public, still I would like to reply to all of you on this public media. I still welcome those emails. What I found out is that many people feels like me, they want to be developers and still be compensated for their experience without wanting to take a job as a manager. Their perfect day is a full day of coding and learning. Many believe their companies will never pay a manager’s salary to a developer no matter what. Most of you ask how to get the ball rolling. And is the later that I’m addressing here, the previous group, will never try. What companies understand developers value and where can I find them? This is a very difficult question to ask, I don’t have a list of those companies or departments, I have seen in my past signs in companies bending backwards to compensate, in more ways the monetary, a developer that is a good resource to them. Allowing the person to move out of the state and still let them work for the company from home is a sign that company goes by individual cases. Allowing them to go to conference that will not benefit the company is another big sign. Simple signs like flexible hours and letting some people work from home. To see those signs you need to be working in that company for awhile and look at the departments where the manager is taking care of their employees in individual cases. Look for the department where people get quiet extra perks, where some people in the department work from home or remotely. In my experience, but not always true, medium to big companies, are prompt to recognize good developers. Then again, some companies just don’t get it and is when you see many technical people managing developers. For all the people that email me stating that developers can also be very good managers, I do not disagree, I just think that a good developers loves writing code, when you remove that part the better salary isn’t enough to keep a developer happy. Burned out developers appreciate being promoted to managers. How do I know I work in a bad company? In my experience I have been a consultant and seen many companies, a few signs I have learned about companies that will not recognize good developers are: When the turn over is pretty high, when developers are moving out in a big rate, no rocket scientist needs to tap you in the shoulder. When the company is looking always to outsource their development resources. The product is not that interesting nor the company cares too much for their final result and support. Code sweat shops. You’ll know when you start working in one of those. Run for the hills! Where do I start? Disclaimer: I have only based this post on Michael “Doc” Norton, this is just my interpretation and ideas. First thing is to look at Michael “Doc” Norton presentation Take Control of Your Development Career http://docondev.blogspot.com/ That should be the first thing any developer should look and follow like it was a pattern. I would personally recommend to find some language or pattern you are interested with and learn it, learn something that will make you happy. Second, join a User Group and get involve in the community. There are hundreds of user groups, and I’m sure you’ll find one in your city or near you town. Code Camps are Developers Meet Ups are also good resources. Third, I would join a open source project you are interested or better yet, create a new open source project with the new technology that you have learn and get coding. Fourth, create a Twitter account and follow the people that talks about the technology you are interested on. If you follow this 4 steps above I think you’ll be on your way, after they are complete, when you release your Open Source project you can say that you accomplished the first steps. Now, do not expect anything to change in your career life, you are changing and should not expect anything in return, besides borrowing some time from sleeping and your family. Creating a good schedule may help you, I find wasted time in many places that I use. Flying for work is actually one of those that allows me to do my best work on a airplane, don’t need to borrow time from anywhere else. Making sure you always have a light, charged laptop is so important. Next steps following the Michael “Doc” Norton Pattern or my interpretation of. First, help run a user group or better yet, start a new user group. I’ll add, as well, go to one conference a year and free development events around your city; Code Camps, Geek Dinners, etc. There are many free events sponsored by different companies for developers to get to know their products, I highly recommend those as the way to get connected. Second, chose a mentor, this is a very hard thing to do I experienced, find an expert in the technology you are learning that has the time for you, it is difficult, I wish you best of luck. Third, learn another technology or pattern, open your horizons a little bit more. Why not, if you had fun previously, keep doing it. Fourth, get involved in forums to answer and ask questions, getting notice in public forums is rewarding for your ego after such a long journey. Final steps following the Michael “Doc” Norton Pattern Teach what you know, become humble on your knowledge, find as many opportunities to teach and to get involved with the community, bring all that to your day job. Mr. Norton talks about getting naked, expose yourself to others in your knowledge and what you do not know. You are never too important for small opportunities, yet don’t  be afraid to take anything big and learn from the experience. Anytime you have the opportunity to talk to somebody that has reach the point the community knows his or her name, means that you should learn from it. Take opportunities that won’t make you money, yet will make you happy. Sometimes you need to spend money and time. Register talks in Code Camps and Dev Meet Ups, those are free, also go to Conference, Development Summits and Geek Diners for example. One day, people will pay you to attend. When will all these pay off? I don’t know. I’m still in the path, there are a few things that during your journey you may get little acknowledgements that you are in the correct path. In my case I think those are the little signs that tells you about your journey. I got awarded the Microsoft Most Valuable Professional for ASP.NET in 2007, 2008, 2009 and 2010. I got selected to speak at the DevConnections in Las Vegas in 2010 and Orlando 2011. I do believe that I do have a long way to go, yet what I do makes me happy and I hope I can keep doing for years to come. Every year I can see an improvement on my code, and more frameworks and languages are under my belt, I learn to embrace them all as well as in my daily job, I have been able to work in a few projects beyond my department. I’m a learner and believer of the Michael “Doc” Norton pattern. Looking forward to learn more about it to be able to apply it better. In my short journey I now see my mistakes, I did a few things right, I have been listening the intelligent people and not being afraid to move along the technology changes. In my professional life, I have tried to avoid being placed in only one technology and product. I have always share my code and never confused anybody that wanted to take over any of my projects, I didn’t think anything I created as my own nor care too much when politics didn’t see my vision. I stayed flexible, ready and visible, yet humble. I keep my head just below the clouds, and avoided managers meetings. I credit my manager for my success, and I faulted publicly only myself for the failures. Hope this helps. Cheers, Al Follow me in Twitter  Read my previous post tweetmeme_url = 'http://weblogs.asp.net/albertpascual/archive/2010/12/09/part-2-career-development-as-a-software-developer-without-becoming-a-manager.aspx'; tweetmeme_source = 'alpascual';

  • What is the economic rationale behind programmers who work on a open source project (free) instead of a commercial project (not free)?

    - by Kim Jong Woo
    I can't understand why some people dedicate so much hour into a completely open source project without closing it and yielding greater profit from it. I don't think profiting from your code is evil, I think it's a great motivator. Why do some people feel that commercial software and generating money from it is bad? There seems to be this black and white thinking that open source = good, commercial = bad. I hardly find this convincing, and often commercial companies which are supported by sales produce very good results. An open source software in the same niche can't compete against the corporation. Of course, sometimes this is completely the other way around where private companies produce inferior product compared to open source counterparts. So help me understand, why do programmers open source their code when there is commercial prospects for it? Shouldn't the rational programmer or human being make every effort to capitalize on their opportunity cost? Working on a open source project for months when you could've spent the same number of hours at commidity wage or some other monetary compensation?

  • Visual Studio 11 not 2011

    - by Daniel Moth
    A little pet peeve of mine is when people incorrectly refer to the Developer Preview (or the upcoming Beta) as Visual Studio 2011 instead of the correct Visual Studio 11. The "11" refers to the version number (internally we call it Dev11). What the product will be called when it is released is anyone's guess (it could keep the name or it could have a year appended to it, or it could be something else, who knows). Even if it does have a year appended to the name, I think it is a safe bet it won't be last year! For reference, version 10 was the previous version of Visual Studio which happened to be released in 2010, hence it got the name Visual Studio 2010. That is what confuses new people to this product I guess... they think that the two-digit number matches the year, just because it coincided like that last year. (btw, internally we called it Dev10). For further reference, older releases were: Visual Studio 2008 (v9) aka "Orcas", Visual Studio 2005 (v8) aka "Whidbey", Visual Studio .NET 2003 (v7.1) aka "Everett", and Visual Studio .NET 2002 (v7) aka "Rainier". Before that, we were in the pre-.NET era with Visual Studio 6 (where the version and the product name matched, without the year appended to the name). So next time you hear someone saying "Visual Studio 2011", point them to this post for some mini-education... thanks. Comments about this post by Daniel Moth welcome at the original blog.

  • SQL SERVER – Question to You – When to use Function and When to use Stored Procedure

    - by pinaldave
    This week has been very interesting week. I have asked few questions to users and have received remarkable participation on the subject. Q1) SQL SERVER – Puzzle – SELECT * vs SELECT COUNT(*) Q2) SQL SERVER – Puzzle – Statistics are not Updated but are Created Once Keeping the same spirit up, I am asking the third question over here. Q3) When to use User Defined Function and when to use Stored Procedure in your development? Personally, I believe that they are both different things - they cannot be compared. I can say, it will be like comparing apples and oranges. Each has its own unique use. However, they can be used interchangeably at many times and in real life (i.e., production environment). I have personally seen both of these being used interchangeably many times. This is the precise reason for asking this question. When do you use Function and when do you use Stored Procedure? What are Pros and Cons of each of them when used instead of each other? If you are going to answer that ‘To avoid repeating code, you use Function’ - please think harder! Stored procedure can do the same. In SQL Server Denali, even the stored procedure can return the result just like Function in SELECT statement; so if you are going to answer with ‘Function can be used in SELECT, whereas Stored Procedure cannot be used’ - again think harder! (link). Now, what do you say? I will post the answers of all the three questions with due credit next week.

  • Code Bubbles: Disruption comes to the IDE

    - by andrewbrust
    If you’re like me, you might see the open source Eclipse IDE as a copy or, more generously, a port of the Microsoft’s Visual Studio for the non-.NET world.  It’s not that Microsoft invented the IDE (I would credit Borland with that), but they really took the idea and ran with it for the first version of Visual Studio .NET in 2002.  The question is whether someone outside of Microsoft could take the modern IDE yet another major step forward in both principle and productivity. I think that has actually happened already, and I think the innovator in question is a second-year Computer Science PhD student at Brown, named Andrew Bragdon.  His project, which he calls Code Bubbles, is an IDE that allows for editing, debugging and exploration of code in “bubbles” which remind me a little bit of the discrete note tiles on OneNote…but they’re much more than that.  Bubbles actually allow for call stack traversal, saved debug sessions, sophisticated breakpoint and value watch behaviors and more.  And because bubbles, unlike windows, are borderless, and focus on code fragments rather than whole files, the de-cluttering effect is unbelievably liberating.  The best way to understand what Code Bubbles does is to watch the screencast video:     Code Bubbles is an IDE for Java development.  Why didn’t Microsoft come up with something like this for .NET devs?  Between the existing features in Visual Studio 2010, its WPF code editor, and the fact that OneNote’s UI bears some affinity to Code Bubbles’, it’s interesting that Microsoft still has not thought outside of its own “box” to get us something like this. Heck, that’s easy for me to say.  But it’s easy for you to say that you’d like something like this in Visual Studio sometime soon.  That’s because the ASP.NET site within UserVoice is taking votes on this very issue.  Just click this link and vote! Thanks to my fellow Microsoft Regional Director Sondre Bjellås for making me aware of Code Bubbles, and to RD Steve Smith for creating the UserVoice voting option.

  • Asus Sonic Master on Asus N53SV

    - by David Winchester
    I have read that there's a problem to get the subwoofer working in these laptops. I tried this solution No sound from external subwoofer but I don't how to prove that the subwoofer is properly functioning. I use Pulseaudio equalizer and the bass sound seems to work fine, but when I go to the Sound Settings, I can't move the bar where it says 'Subwoofer' in my sound card option, so I don't know if everything is alright. If someone has a solution I would like to know, because there isn't much information regarding this. By the way, I'm using Ubuntu 12.04 64 bits. Thanks beforehand, Dave EDIT ----------- Possible Solution Well, I will post a solution that worked for me and I think it will help a lot of users. I finally got the subwoofer working. Besides adding in /etc/modprobe.d/alsa-base.conf the line options snd-hda-intel model=asus-mode4 I deleted the lines with load-module module-combine and module-combine-sink in /etc/pulse/default.pa (in the home folder there's also a ~/.pulse/default.pa file, I don't know if it has the lines too) To assure all the channels are working, I think this command tells me that speaker-test -c6 -l1 -twav I use pulseaudio-equalizer and the bass sounds very well when properly adjusted. Also, all the channels seems to work fine and the sound is even better than in Windows (where I don't have an equalizer). I pointed out before a module-combine and module-combine-sink problem, because one day I turned on my laptop and pulseaudio didn't work. So I deleted the lines with that names (don't know if they came by default, maybe I added them sometime when I was trying to fix my speakers). After all this, I can now move the Subwoofer bar in the Sound configuration. Anyways, the Equalizer does a great job and it improves the sound a lot.

  • What Would Google Do?

    - by David Dorf
    Last year I read Jeff Jarvis' book What Would Google Do? and found it very interesting. Jeff is a long-time journalist that's been studying technology, and more specifically the internet. He used his skills to reverse-engineer Google into a list of "Google rules," then goes on to describe a futuristic world driven by these rules. Its an interesting look at crowd-sourcing, openness, and collaboration across many industries, including retail (Google Shops). This year Jeff Jarvis will be a keynote speaker at CrossTalk, Oracle's user conference dedicated to the retail industry. This year's theme is... Retail Redefined: Redesign. Reinvigorate. Reimagine. I think that's pretty appropriate given the massive changes the industry has undergone during the last three years. The thing I really like about this conference is that we try to let the retailers do most of the talking. I'm very interested in hearing about the innovative projects they've got brewing, and where they think our industry is heading. I'll be speaking, but I'm not sure about what so let me know of any interesting topics.

  • Elastic versus Distributed in caching.

    - by Mike Reys
    Until now, I hadn't heard about Elastic Caching yet. Today I read Mike Gualtieri's Blog entry. I immediately thought about Oracle Coherence and got a little scare throughout the reading. Elastic Caching is the next step after Distributed Caching. As we've always positioned Coherence as a Distributed Cache, I thought for a brief instance that Oracle had missed a new trend/technology. But then I started reading the characteristics of an Elastic Cache. Forrester definition: Software infrastructure that provides application developers with data caching services that are distributed across two or more server nodes that consistently perform as volumes grow can be scaled without downtime provide a range of fault-tolerance levels Hey wait a minute, doesn't Coherence fullfill all these requirements? Oh yes, I think it does! The next defintion in the article is about Elastic Application Platforms. This is mainly more of the same with the addition of code execution. Now there is analytics functionality in Oracle Coherence. The analytics capability provides data-centric functions like distributed aggregation, searching and sorting. Coherence also provides continuous querying and event-handling. I think that when it comes to providing an Elastic Application Platform (as in the Forrester definition), Oracle is close, nearly there. And what's more, as Elastic Platform is the next big thing towards the big C word, Oracle Coherence makes you cloud-ready ;-) There you go! Find more info on Oracle Coherence here.

  • Is copy paste programming bad ?

    - by ring bearer
    With plain google as well as google code search tools it is easy to find how to program using some resource or solve certain problems ( such as a Java class, or a ftp block in perl etc) and so developers are so tempted to just purely copy paste the code (in a way re-use) - is this an incompetency? I have done this myself though I think I am a better programmer than many others I have seen. Who has the time to RTFM? In this age of information abundance, I do not think that copy paste programming is bad. Isn't that what sites like stackoverflow do anyway? People ask - ok here is my problem - how to solve it? now someone will post complete code and the person who asked the question would simply copy paste the most voted answer. No matter how small the problem is. I am working with a bunch of young coders who heavily rely on internet to get their job done. I see convenience (for example, you may be quite good with algorithms and such but you may not know how to use a BufferedReader in Java - would you read complete Javadoc for BufferedReader or look up some example of using it somewhere??) in copy pasting and modifying code to get the job done. What are the real dangers of copy paste coding that can impact their competency?

  • Rendering with Direct3D

    - by Jamie
    Hi, I'm slightly confused about how Direct3D rendering works. Basically, as long as I render to one surface, everything is fine. But when I try rendering to multiple surfaces, it seems like everything is still rendered to one surface. I think there's something wrong with my calls. For each update cycle this is what I do 1. device-BeginScene() 2. sprite-Begin(...) ... A bunch of GetRenderTarget to store the old render target, then SetRenderTarget to set a new surface, and then things like CreateVertexBuffer, SetTexture, etc to draw on the new render target. Then resetting to the old render target. sprite-Draw([the back buffer]) (the back buffer is actually another surface, not the actual back buffer. But here it is being drawn onto the actual back buffer, I think) sprite-End() device-EndScene() device-Present(...) Also, it seems like if I mix sprite drawing and non-sprite drawing onto a surface, that first one set of render commands is executed and then the other set, rather than in order by when each command was called. If anyone could shed light on any of this, it would be much appreciated.

  • A client wants us to screen work machines for pornography. Is it possible?

    - by Scant Roger
    A long-time client has asked us to help screen their work machines for pornography. They're worried about liability if sensitive materials were found. Their main concerns (for obvious reasons) are video, audio, and image files. If possible, they'd also like to scan text-based documents for inappropriate content. They have a hierarchy of not-for-work content starting with blatantly illegal (I don't have to list details), moving down to obviously offensive, and also including things that may be offensive to some - think lingerie ads, joke cards featuring butt cracks, and anything related to Howie Mandel. My questions are: Is this ethical? I think it is since every employee legally agrees that their work machine belongs to the company and is subject to search. The screenings are not to occur on personal machines brought to work. Is it feasible? I've done a lot of image processing/indexing but this seems like a whole new world of complexity. Any references to successful techniques for discovering porn? Is it appropriate for me to archive the results when something is discovered?

  • Relationship between C#, .NET, ASP, ASP.NET etc

    - by Samuel Walker
    I'm really unclear on the difference between C#, C#.NET and the same for ASP and other '.NET' languages. From what I understand, .NET is a library/framework of... things. I think they're essentially access to Windows data such as form elements etc, but that doesn't seem to apply for ASP.NET. In addition, I see people calling themselves '.NET' developers. Does this mean they're fluent in C#, ASP and other languages? Finally, I never see C# without .NET attached. Is C# tied that closely to .NET as to be unusable without it? In summary: what exactly does .NET provide? How does it relate to C# and ASP etc? What does 'a .NET developer' mean? And finally, why do you never see C# without .NET? [As an aside, I realise these are multiple questions, but I think they are very inter-related (or at least that is the impression that browsing Programmers / SO etc has given me)].

  • How to implement curved movement while tracking the appropriate angle?

    - by Vexille
    I'm currently coding a 2D top-down car game which will be turn-based. And since it's turn-based, the cars won't be controlled directly (i.e. with a simple velocity vector that adjusts its angle when the player wants to turn), but instead it's movement path has to be planned beforehand, and then the car needs to follow the path when the turn ends (think Steambirds). This question has some interesting information, but its focus is on homing-missile behaviour, which I kinda had figured out, but doesn't really apply to my case, I think, since I need to show a preview of the path when the player is planning his turn, then have the car follow that path. In that same question, there's an excellent answer by Andrew Russel which mentions Equations of Motion and Bézier's Curve. Some of his other suggestions of implementation are specific to XNA though, so they don't help much (I'm using Marmalade SDK). If I assume Bézier's Curve as the solution of choice, I'm left with one specific problem: I'll have the car's position (the first endpoint) and the target/final position (the last endpoint), but what should I use as the control point (assuming a square/quadratic curve)? And whether I use Bézier's Curve or another parametric equation, I'd still be left with another issue: the car can't just follow the curve, it must turn (i.e. adjust its angle) accordingly. So how can I figure out which way the car should be pointing to at any given point in the curve?

  • Visual Studio ALM MVP of the Year 2011

    - by Martin Hinshelwood
    For some reason this year some of my peers decided to vote for me as a contender for Visual Studio ALM MVP of the year. I am not sure what I did to deserve this, but a number of people have commented that I have a rather useful blog. I feel wholly unworthy to join the ranks of previous winners: Ed Blankenship (2010) Martin Woodward (2009) Thank you to everyone who voted regardless of who you voted for. If there was a prize for the best group of MVP’s then the Visual Studio ALM MVP would be a clear winner, as would the product group of product groups that is Visual Studio ALM Group. To use a phrase that I have learned since moving to Seattle and probably use too much: you guys are all just awesome. I have tried my best in the last year to document not only every problem that I have had with Team Foundation Server (TFS), but also to document as many of the things I am doing as possible. I have taken some of Adam Cogan’s rules to heart and when a customer asks me a question I always blog the answer and send them a link. This allows both my blog and my understanding of TFS to grow while creating a useful bank of content. The idea is that if one customer asks, all benefit. I try, when writing for my blog, to capture both the essence and the context for a problem being solved. This allows more people to benefit as they do not need to understand the specifics of an environment to gain value. I have a number of goals for this year that I think will help increase value in the community: persuade my new colleagues at Northwest Cadence to do more blogging (Steve, Jeff, Shad and Rennie) Rangers Project – TFS Iteration Automation with Willy-Peter Schaub, Bill Essary, Martin Hinshelwood, Mike Fourie, Jeff Bramwell and Brian Blackman Write a book on the Team Foundation Server API with Willy-Peter Schaub, Mike Fourie and Jeff Bramwell write more useful blog posts I do not think that these things are beyond the realms of do-ability, but we will see…

  • SQL SERVER – Reducing Page Contention on TempDB

    - by pinaldave
    I have recently received following email. “We are using TraceFlag 1118 to reduce the tempDB contention on our servers (2000 and 2005). What is your opinion? We have read lots of material, would you please answer me in single line.” Wow, this was very interesting question. What intrigued me was the second last where I am asked to answer in a single line. There is something about this strong email, I feel like blogging it here. I think I can talk over this subject forever – well, there is no clear answer. There are so many caveats about everything.  Again, I must stay honest to the request about answering in single line. I also do not like to answer which is YES/NO. What should I do? Let me ask this question to community today? What will you answer to this email? Let me start this by answering it myself in one line and taking one side. “I enable this trace flag in SQL Server 2000 without hot patch or service pack and not in later versions (2005+) onwards as code is improved”. What do you do in this case? The best answer will feature in this blog with due credit. Regarding further read and hint here is Microsoft KB which I think is very helpful. In quick summary: (Read KB for accuracy) When any page is allocated first 8 pages are allocated in mixed extended. This trace flag allocates uniform extended at the time, reducing contention. You can enable this trace flag at startup.
