  • Clean Code Development & Flexible work environment - MSCC 26.10.2013

    Finally, some spare time to summarize my impressions and experiences of the recent meetup of Mauritius Software Craftsmanship Community. I already posted my comment on the event and on our social media networks: Professional - It's getting better with our meetups and I really appreciated that 'seniors' and 'juniors' were present today. Despite running a little bit out of time it was really great to see more students coming to the gathering. This time we changed location for our Saturday meetup and it worked out very well. A big thank you to Ebene Accelerator, namely Mrs Poonum, for the ability to use their meeting rooms for our community get-together. Already some weeks ago I had a very pleasant conversation with her about the MSCC aims, 'mission' and how we organise things. Additionally, I think that an environment like the Ebene Accelerator is a good choice as it acts as an incubator for young developers and start-ups. Reactions from other craftsmen Before I put my thoughts about our recent meeting down, I'd like to mention and cross-link to some of the other craftsmen that were present: "MSCC meet up is a massive knowledge gaining strategies for students, future entrepreneurs, or for geeks all around. Knowledge sharing becomes a fun. For those who have not been able to made it do subscribe on our MSCC meet up group at meetup.com." -- Nitin on Learning is fun with #MSCC #Ebene Accelerator "We then talked about the IT industry in Mauritius, salary issues in various field like system administration, software development etc. We analysed the reasons why people tend to hop from one company to another. That was a fun debate." -- Ish on MSCC meetup - Gang of Geeks "Flexible Learning Environment was quite interesting since these lines struck cords : "You're not a secretary....9 to 5 shouldn't suit you"....This allowed reflection...deep reflection....especially regarding the local mindset...which should be changed in a way which would promote creativity rather than choking it till death..." -- Yannick on 2nd MSCC Monthly Meet-up And others on Facebook... ;-) Visual impressions are available on our Meetup event page. More first time attendees We great pleasure I noticed that we have once again more first time visitors. A quick overlook showed that we had a majority of UoM students in first, second or last year. Some of them are already participating in the UoM Computer Club or are nominated as members of the Microsoft Student Partner (MSP) programme. Personally, I really appreciate the fact that the MSCC is able to gather such a broad audience. And as I wrote initially, the MSCC is technology-agnostic; we want IT people from any segment of this business. Of course, students which are about to delve into the 'real world' of working are highly welcome, and I hope that they might get one or other glimpse of experience or advice from employees. Sticking to the schedule? No, not really... And honestly, it was a good choice to go a little bit of the beaten tracks. I mean, yes we have a 'rough' agenda of topics that we would like to talk about or having a presentation about. But we keep it 'agile'. Due to the high number of new faces, we initiated another quick round of introductions and I gave a really brief overview of the MSCC. Next, we started to reflect on the Clean Code Developer (CCD) - Red Grade which we introduced on the last meetup. Nirvan was the lucky one and he did a good job on summarizing the various abbreviations of the first level of being a CCD. Actually, more interesting, we exchanged experience about the principles and practices of Red Grade, and it was very informative to get to know that Yann actually 'interviewed' a couple of friends, other students, local guys working in IT companies as well as some IT friends from India in order to counter-check on what he learned first-hand about Clean Code. Currently, he is reading the book of Robert C. Martin on that topic and I'm looking forward to his review soon. More output generates more input What seems to be like a personal mantra is working out pretty well for me since the beginning of this year. Being more active on social media networks, writing more article on my blog, starting the Mauritius Software Craftsmanship Community, and contributing more to other online communities has helped me to receive more project requests, job offers and possibilities to expand my business at IOS Indian Ocean Software Ltd. Actually, it is not a coincidence that one of the questions new craftsmen should answer during registration asks about having a personal blog. Whether you are just curious about IT, right in the middle of your Computer Studies, or already working in software development or system administration since a while you should consider to advertise and market yourself online. Easiest way to resolve this are to have online profiles on professional social media networks like LinkedIn, Xing, Twitter, and Google+ (no Facebook should be considered for private only), and considering to have a personal blog. Why? -- Be yourself, be proud of your work, and let other people know that you're passionate about your profession. Trust me, this is going to open up opportunities you might not have dreamt about... Exchanging ideas about having a professional online presence - MSCC meetup on the 26th October 2013 Furthermore, consider to put your Curriculum Vitae online, too. There are quite a number of service providers like 1ClickCV, Stack Overflow Careers 2.0, etc. which give you the ability to have an up to date CV online. At least put it on your site, next to your personal blog. Similar to what you would be able to see on my site here. Cyber Island Mauritius - are we there? A couple of weeks ago I got a 'cold' message on LinkedIn from someone living in the U.S. asking about the circumstances and conditions of the IT world of Mauritius. He has a great business idea, venture capital and is currently looking for a team of software developers (mainly mobile - iOS) for a new startup here in Mauritius. Since then we exchanged quite some details through private messages and Skype conversations, and I suggested that it might be a good chance to join our meetup through a conference call and see for yourself about potential candidates. During approximately 30 to 40 minutes the brief idea of the new startup was presented - very promising state-of-the-art technology aspects and integration of various public APIs -, and we had a good Q&A session about it. Also thanks to the excellent bandwidth provided by the Ebene Accelerator the video conference between three parties went absolutely well. Clean Code Developer - Orange Grade Hahaha - nice one... Being at the Orange Tower at Ebene and then talking about an Orange Grade as CCD. Well, once again I provided an overview of the principles and practices in that rank of Clean Code, and similar to our last meetup we discussed on the various aspect of each principle, whether someone already got in touch with it during studies or work, and how it could affect their future view on their source code. Following are the principles and practices of Clean Code Developer - Orange Grade: CCD Orange Grade - Principles Single Level of Abstraction (SLA) Single Responsibility Principle (SRP) Separation of Concerns (SoC) Source Code conventions CCD Orange Grade - Practices Issue Tracking Automated Integration Tests Reading, Reading, Reading Reviews Especially the part on reading technical books got some extra attention. We quickly gathered our views on that and came up with a result that ranges between Zero (0) and up to Fifteen (15) book titles per year. Personally, I'm keeping my progress between Six (6) and Eight (8) titles per year, but at least One (1) per quarter of a year. Which is also connected to the fact that I'm participating in the O'Reilly Reader Review Program and have a another benefit to get access to free books only by writing and publishing a review afterwards. We also had a good exchange on the extended topic of 'Reviews' - which to my opinion is abnormal difficult here in Mauritius for various reasons. As far as I can tell from my experience working with Mauritian software developers, either as colleagues, employees or during consulting services there are unfortunately two dominant pattern on that topic: Keeping quiet Running away Honestly, I have no evidence about why these are the two 'solutions' on reviews but that's the situation that I had to face over the last couple of years. Sitting together and talking about problematic issues, tackling down root causes of de-motivational activities and working on general improvements doesn't seem to have a ground within the IT world of Mauritius. Are you a typist or a creative software craftsman? - MSCC meetup on the 26th October 2013 One very good example that we talked about was the fact of 'job hoppers' as you can easily observe it on someone's CV - those people change job every single year; for no obvious reason! Frankly speaking, I wouldn't even consider an IT person like to for an interview. As a company you're investing money and effort into the abilities of your employees. Hiring someone that won't stay for a longer period is out of question. And sorry to say, these kind of IT guys smell fishy about their capabilities and more likely to cause problems than actually produce productive results. One of the reasons why there is a probation period on an employment contract is to give you the liberty to leave as early as possible in case that you don't like your new position. Don't fool yourself or waste other people's time and money by hanging around a full year only to snatch off the bonus payment... Future outlook: Developer's Conference Even though it is not official yet I already mentioned it several times during our weekly Code & Coffee sessions. The MSCC is looking forward to be able to organise or to contribute to an upcoming IT event. Currently, the rough schedule is set for April 2014 but this mainly depends on availability of location(s), a decent time frame for preparations, and the underlying procedures with public bodies to have it approved and so on. As soon as the information about date and location has been fixed there will be a 'Call for Papers' period in order to attract local IT enthusiasts to apply for a session slot and talk about their field of work and their passion in IT. More to come for sure... My resume of the day It was a great gathering and I am very pleased about the fact that we had another 15 craftsmen (plus 2 businessmen on conference call plus 2 young apprentices) in the same room, talking about IT related topics and sharing their experience as employees and students. Personally, I really appreciated the feedback from the students about their current view on their future career, and I really hope that some of them are going to pursue their dreams. Start promoting yourself and it will happen... Looking forward to your blogs! And last but not least our numbers on Meetup and Facebook have been increased as a direct consequence of this meetup. Please, spread the word about the MSCC and get your friends and colleagues to join our official site. The higher the number of craftsmen we have the better chances we have t achieve something great! Thanks!

  • EclipseLink does multitenancy. Today.

    - by alexismp
    So you heard Java EE 7 will be about the cloud, but that didn't mean a whole lot to you. Then it was characterized as PaaS, something in between IaaS and SaaS. And finally it all became clear when referenced as support for multitenancy. Or did it? When it comes to JPA and persistence is general, multitenancy is defined as the ability to share a database schema among various groups of users (i.e. tenants). This means that there is no database setup or reconfiguration required as the data is co-located in the same database. EclipseLink 2.3 (the Indigo train release) let's you do just that by supporting tenant discriminator column(s) via annotations or XML with applications providing values for these discriminators via an API or PU configuration. Check out details here. EclipseLink 2.3 is scheduled to be the default and supported JPA provider for GlassFish 3.1.1. Another nice feature of this release is the ability to extend persistence units on the fly. The GlassFish Podcast has an interview up with EclipseLink's Doug Clarke. Expect more on multitenancy across the Java EE spectrum as the specification work progressed.

  • We'll be at QCon San Francisco!

    - by Carlos Chang
    Oracle Technology Network is a Platinum sponsor at QCon San Francisco. Don’t miss these great developer focused sessions: Shay Shmeltzer - How we simplified Web, Mobile and Cloud development for our own developers? - the Oracle Story Over the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of the largest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud based development and deployment? Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan Smith - Project Lambda in Java 8 Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun Gupta - JSR 356: Building HTML5 WebSocket Applications in Java The family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The complete conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more! At the Oracle booth, we’ll also be covering: Oracle ADF Mobile Oracle Developer Cloud Service Oracle ADF Essentials NetBeans Project Easel Hope to see you there!

  • JavaOne + Develop Registration is Open!

    - by justin.kestelyn
    Welcome to "The Zone". Here's what the new JavaOne + Develop registration Website says: The world's most important developer conferences are creating the world's coolest neighborhood for the developer community. Having been intimately involved in the planning process, I can vouch for that statement. Remember, if either co-located conference - JavaOne or Oracle Develop - are the confines of your interest, you can experience either one in standalone mode, if you like (although there are some areas of common interest, of course). Or, considering that a single Full Conference Pass gives you access to both of them, you can partake in any measure that you like. It's up to you. Either way, you will get access not only to session content and keynotes, but also to the massive OTN Night party on Monday night, to open unconference sessions, and to the legendary Appreciate Night concert (acts TBD) on Wednesday. Furthermore, as is customary, the Oracle Technology Network team will offer a full slate of community-focused activities and goodies while the conferences are running - more details on those as we have them. A GOOD time is ensured for all; I look forward to seeing you there!

  • Decorator not calling the decorated instance - alternative design needed

    - by Daniel Hilgarth
    Assume I have a simple interface for translating text (sample code in C#): public interface ITranslationService { string GetTranslation(string key, CultureInfo targetLanguage); // some other methods... } A first simple implementation of this interface already exists and simply goes to the database for every method call. Assuming a UI that is being translated at start up this results in one database call per control. To improve this, I want to add the following behavior: As soon as a request for one language comes in, fetch all translations from this language and cache them. All translation requests are served from the cache. I thought about implementing this new behavior as a decorator, because all other methods of that interface implemented by the decorater would simple delegate to the decorated instance. However, the implementation of GetTranslation wouldn't use GetTranslation of the decorated instance at all to get all translations of a certain language. It would fire its own query against the database. This breaks the decorator pattern, because every functionality provided by the decorated instance is simply skipped. This becomes a real problem if there are other decorators involved. My understanding is that a Decorator should be additive. In this case however, the decorator is replacing the behavior of the decorated instance. I can't really think of a nice solution for this - how would you solve it? Everything is allowed, even a complete re-design of ITranslationService itself.

  • What is the proper response to lousy error message?

    - by William Pursell
    I've just come across (for the 47 millionth time) some code that looks like this: except IOError, e: print "Problems reading file: %s." % filename sys.exit( 1 ) My first reaction is very visceral: the person who coded this is a complete idiot. How hard is it to print error messages to stderr and to include the system error message in the string? I haven't used python in years, and it took me all of 4 minutes to track down the documentation to figure out how to get the error message from the exception object e and the syntax for printing to stderr. My "complete idiot" reaction was slightly lessened since at least a non-zero value is passed to sys.exit, but I still find this code offensive. My prime thought is that the developer who wrote this is a complete novice for whom I have zero respect. Am I over-reacting? Surely there are excuses for all sorts of bad coding practices, but is there anything that can possibly excuse this sort of $#|t? I guess there are two question here: one is a duplicate of What are developer's problems with helpful error messages?, and the other is "am I over-reacting, or is it valid to conclude that the author of the above code is a novice?"

  • Office arangement - comfort vs. teamwork?

    - by finrod
    Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.

  • Book Review: Professional ASP.Net MVC4

    - by Sam Abraham
    The past few weeks have been particularly busy as I continue to dedicate a bigger portion of my free time to refreshing my memory and enhancing my knowledge of best practices pertaining to technologies we plan on using for a major upcoming project. In this blog post, I will be providing a brief overview of my latest reading “Professional ASP.Net MVC4” by Jon Galloway, Phil Haack, Brad Wilson and K. Scott Allen. This book is a must read for web developers looking to enhance their MVC expertise with best practices and tips shared from recognized industry experts. This book takes the reader on a 16-chapter long journey towards being a better ASP.NET MVC developer with chapter 16 putting all information covered in practical context by dissecting the implementation of Nuget.org, a real-life open-source, ASP.NET MVC project.  All code samples referenced in this book are conveniently accessible via NuGet, a free, open-source Library package manager that installs as a Visual Studio Extension. Chapters 2, 3 and 4 thoroughly cover MVC’s various components: Controllers “C”, Views “V” and Models “M” respectively. Chapter 5 covers additional extension methods (Helpers) provided to speed and ease the use of common HTML elements such as forms, textboxes, grids, to name a few… Chapter 6 tackles built-in validation while providing examples and use cases on implementing custom validation that plugs into the MVC framework. Chapters 7 thru 13 discusses the latest on Membership, Ajax, Routing, NuGet and the ASP.Net Web API. Chapters 12 (Dependency Injection) and 13 (Unit Testing) demonstrate a big competitive advantage of MVC with its ease of test-ability and plug-ability. Chapters 14 and 15 targets the advanced developer showcasing how to extend MVC to customize and replace every piece in the framework.In conclusion, I strongly recommend Professional ASP.NET MVC 4 as an excellent read for both developers already using MVC as well as those getting started with the framework.   Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group.  You can access my reviews of books I recently read: Professional ASP.NET Design Patterns Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

  • Why do programmers write closed source applications and then make them free? [closed]

    - by Ken
    As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubicle. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

  • Client-Server MMOG & data structures sync when joining / playing

    - by plang
    After reading a few articles on MMOG architecture, there is still one point on which I cannot find much information: it has to do with how you keep in sync server data on the client, when you join, and while you play. A pretty vague question, I agree. Let me refine it: Let's say we have an MMOG virtual world subdivided into geographical cells. A player in a cell is mostly interested in what happens in the cell itself, and all the surrounding cells, not more. When joining the game for the first time, the only thing we can do is send some sort of "database dump" of the interesting cells to the client. When playing, I guess it would be very inefficient to do the same thing regularly. I imagine the best thing to do is to send "deltas" to the client, which would allow keeping the local database in sync. Now let's say the player moves, and arrives in another cell. Surrounding cells change, and for all the new cells the player subscribes, the same technique as used when joining the game has to be used: some sort of "database dump". This mechanic of joining/moving in a cell-based MMOG virtual world interests me, and I was wondering if there were tried and tested techniques in this domain. Thanks!

  • Brain picking during job interview

    - by mark
    Recently, I had a job interview at a big Silicon Valley company for a senior software developer/R&D position. I had several technical phone screens, an all day on-site interview and more technical phone screens for another position later. The interviews went really well, I have a PhD and working experience in the area I was applying for yet no offer was made. So far, so good. It was an interesting experience, I am employed, absolutely no hard feelings about this. Some of the interviewers asked really detailed questions to the point of being suspicious about new technologies I have been working on. These technologies are still in development and have not come to market yet. I know some major hardware/software companies are working on this too. I have had many interviews before and based on my former interviewing experience and the impression some of the interviewers left behind, I know now all this company wanted from me is to extract some ideas about what I did in this field. Remember, I am referring to a R&D position, not the standard software developer stuff. Has anybody encountered this situation so far? And how did you deal with it? I am not so much concerned about "stealing" ideas but more about being tricked into showing up for an interview when there is no intension to hire anyway. I am considering refusing technical interviews in the future and instead proposing a trial period in which the company can easily reconsider its hiring decision.

  • How to effectively design a piece of software

    - by ti83plus
    Im a compsci student and ive got some experience in various languages and paradigms c/java/python/ruby/html/css/scheme/sql/asp(classic). I realise that i want to have some software in my portfolio for future job hunting even tho i still have 2 years left of my education. Ive got a pretty good idea of what i want to make, its a webapp. Most shops around here are either .net or java and since i know java best and dont have access to ms developer tools im thinking i should go with java. Even tho i feel i know the principles of OOP pretty good ive got no clue how to go from my idea to a working solution. Where can i access information about designing the underlying architechture of my solution? Also i would like to know what other technologies i should train on, my current list includes javascript(and possibly a javascript library) some sort of java web framework tips are appreciated. I would like to add support for android/iphone apps in the future and this is something i have to take into account when designing the app. I have done a course on software engineering but i found this to be more centered around project management ideas then the actual design and implementation. So i would like tips on technologies i should focus on to get the most out of my time without the massive overhead of huge config processes but at the same time keep my project viable in a business sense, so that i use technologies that are relevant for business (java developer jobs). And i would also like tips on where i can learn more about the design process around a software project, i will be working mostly alone. But i find the approach ive used up until now (start coding and figure it out as you go) wont suffice.

  • Oracle as a Service in the Cloud

    - by Jason Williamson
    This should really be a Tweet, but I guess I'm writing a bit more. In theme of data migration and legacy modernization, I am seeing more and more of a push to consolidate data sources, especially from non-oracle to oracle in an effort to save dollars. From a modernization perspective, this fits in quite well. We are able to migrate things like Terradata, Sybase and DB2 and put that all into an Oracle database and then provide that as a OaaS (Oracle as a Service) Cloud offering. This seems to be a growing trend, and not unlike the cool RDS Amazon Database cloud being built on Oracle as well. We again find ourselves back in the similar theme of migration, however. The target technology sounds like a winner (COBOL to Java/SOA...DB2/Datacom/Adabas to Oracle) but the age-old problem of how to get there still persists. It it not trivial to migrate large amounts of pre-relational or "devolved" relational data. To do this, we again must revert back to a tight roadmap to migration and leverage the growing tools and services that we have. I'm working on a couple of new sections and chapters for a book that Tom and Prakash and I are writing around Database Migration and Consolidation. I'll share some snipits shortly.

  • The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

    - by Hunter2
    Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

  • How do you communicate improvements in tools and process to the development team?

    - by birryree
    Hi everyone, My team does a lot of internal tooling and infrastructure work - you can think of us as a small scale version of the teams Facebook, Etsy, Netflix, etc. who build all the infrastructure for scaling their services up to thousands/tens of thousands of servers and supporting millions of users. Lately, we've been running full steam ahead improving much of the tools we use internally, like tools for automatically creating new servers, setting up new application instances, etc. An end result of this has been decreased developer frustration, but increased 'ignorance' by most of the developer team about how to use our tools correctly and effectively. More often than not, my team will be asked by other teams to help them use the tools. Solutions we've thought up or things already in place: All our code is relatively simple and self-explanatory, with good comments where necessary, so developers could read the scripts. Counterargument: You can guess this isn't a particularly good idea, having people read our tools' code to figure out how to use it. All our code is committed to Subversion with very detailed commit messages about changes, developers could read the commit emails. Counterargument: Expect the developers to read all our commits? Ludicrous. Wiki - we have an internal company wiki, that we try to maintain with up to date information, but as we are moving so fast, the wiki has to keep pace as well. Counterargument: As mentioned, we move fast in my team, as more improvements on our tools are added daily. Again still relies on people to read something that might change constantly. Email the team? We could email the team when we have a glut of improvements to communicate. So as you can all see, we are trying to find new ideas, and explore options we haven't thought of yet. Anyone else ever been in a similar situation and have some guidance?

  • Is it wise for a programmer to move into management?

    - by Desolate Planet
    Many times, a developer has suggested that I become a team leader because I'm motivated, but during my career in the IT industry, I've seen so many people who are great at programming, move into management and they are miserable. I've also seen many managers return to programming stating "I'm a technical person, I like technical problems". If this is such a common thing, why do developers feel compelled to leave the technical domain and move into management? Sure you'll have more money and more control, but if you don't enjoy your work and take your problems out on your tream. Secondly, I've been asked in developer interviews, "Would you consider leading a team?" and I'm always tempted to cite the Peter Principle based on what I've seen. I am interested in furthering myself, but not in the way the company may want i.e "Vice President of department blah". To be honest, I've seen this more often in the corporate world than in small development houses and it's always put me off ever going back to a corporate environment. I just feel that this is becoming more and more the norm and it's impacting team morale and degrading the quality of the work. Question: Based on what I've said, Is it a smart move for a technical person to move into management?

  • What are some general guidelines for setting up an iOS project I will want to personally publish but sell in the future?

    - by RLH
    I have an idea for a personal iOS project that I would like to write and release to the iOS store. I'm the type of developer who enjoys developing and publishing. I want to write quality software and take care of my customers. Assuming that I wrote an application that had reasonable success, there is a fair chance that I would want to sell the ownership rights of the app to another party and I'd use the proceeds to develop my next personal project which, in turn, I'd probably want to sell in the future. With that said, what are some general guidelines for creating, making and publishing an iOS project that I will eventually want to transfer to another company/developer? I know this is a bit of a broad question, but I request that the given advice be a general list of tips, suggestions and pitfalls to avoid. If any particular bullet point on your list needs more explanation, I'll either search for the answer or post a new question specific to that requirement. Thank you! Note Regarding this Question I am posting this question on Programmers.SO because I think that this is an issue of software architecting, seeking advice for setting a new application project and publishing a project to the Apple iOS store-- all within the requirements for questions on this site.

Cloud API and service designers, stop thinking small | Cloud Computing - InfoWorld "The focus must shift away from fine-grained APIs that provide some type of primitive service, such as pushing data to a block of storage or perhaps making a request to a cloud-rooted database," says InfoWorld's David Linthicum. "To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions -- inside and outside the enterprise."

  • PostgreSQL, Ubuntu, NetBeans IDE (Part 1)

    - by Geertjan
    While setting up PostgreSQL from scratch, with the aim to use it in NetBeans IDE, I found the following resources helpful: http://railskey.wordpress.com/2012/05/19/postgresql-installation-in-ubuntu-12-04/ http://ohdevon.wordpress.com/2011/09/17/postgresql-to-netbeans-1/ http://ohdevon.wordpress.com/2011/09/19/postgresql-to-netbeans-2/ For quite a while I had problems relating to  "/var/run/postgresql/.s.PGSQL.5432", which had something to do with "postmaster.pid", which I somehow solved via a link I can't find anymore, and which may not have been a problem to begin with. A key moment was this one, which was useful for setting the password of a new user I'd created: http://stackoverflow.com/questions/7695962/postgresql-password-authentication-failed-for-user-postgres This was useful for setting up a table in my database, which I did by pasting in the below into NetBeans after I made the connection there: http://use-the-index-luke.com/sql/example-schema/postgresql/where-clause Now I have a database set up with all permissions everywhere (which turned out to be the hard part) correct: The next step will be to create a NetBeans Platform application based on this database. I'm assuming it shouldn't be any different to what's described in the NetBeans Platform CRUD Tutorial.

  • Microsoft releases Visual Studio 2010 SP1

    - by brian_ritchie
    Microsoft has been beta testing SP1 since December of last year.  Today, it was released to MSDN subscribers and will be available for public download on March 10, 2011.The service pack includes a slew of fixes, and a number of new features: Silverlight 4 supportBasic Unit Testing support for the .NET Framework 3.5Performance Wizard for SilverlightIntelliTrace for 64-bit and SharePointIIS Express supportSQL CE 4 supportRazor supportHTML5 and CSS3 support (IntelliSense and validation)WCF RIA Services V1 SP1 includedVisual Basic Runtime embeddingALM Improvements Of all the improvements, IIS Express probably has the largest impact on web developer productivity.  According to Scott Gu, it provides the following:It’s lightweight and easy to install (less than 10Mb download and a super quick install)It does not require an administrator account to run/debug applications from Visual Studio It enables a full web-server feature set – including SSL, URL Rewrite, Media Support, and all other IIS 7.x modules It supports and enables the same extensibility model and web.config file settings that IIS 7.x support It can be installed side-by-side with the full IIS web server as well as the ASP.NET Development Server (they do not conflict at all) It works on Windows XP and higher operating systems – giving you a full IIS 7.x developer feature-set on all OS platforms IIS Express (like the ASP.NET Development Server) can be quickly launched to run a site from a directory on disk.  It does not require any registration/configuration steps. This makes it really easy to launch and run for development scenarios.Good stuff indeed.  This will make our lives much easier.  Thanks Microsoft...we're feeling the love!

  • Displaying a Paged Grid of Data in ASP.NET MVC

    This article demonstrates how to display a paged grid of data in an ASP.NET MVC application and builds upon the work done in two earlier articles: Displaying a Grid of Data in ASP.NET MVC and Sorting a Grid of Data in ASP.NET MVC. Displaying a Grid of Data in ASP.NET MVC started with creating a new ASP.NET MVC application in Visual Studio, then added the Northwind database to the project and showed how to use Microsoft's Linq-to-SQL tool to access data from the database. The article then looked at creating a Controller and View for displaying a list of product information (the Model). Sorting a Grid of Data in ASP.NET MVC enhanced the application by adding a view-specific Model (ProductGridModel) that provided the View with the sorted collection of products to display along with sort-related information, such as the name of the database column the products were sorted by and whether the products were sorted in ascending or descending order. The Sorting a Grid of Data in ASP.NET MVC article also walked through creating a partial view to render the grid's header row so that each column header was a link that, when clicked, sorted the grid by that column. In this article we enhance the view-specific Model (ProductGridModel) to include paging-related information to include the current page being viewed, how many records to show per page, and how many total records are being paged through. Next, we create an action in the Controller that efficiently retrieves the appropriate subset of records to display and then complete the exercise by building a View that displays the subset of records and includes a paging interface that allows the user to step to the next or previous page, or to jump to a particular page number, we create and use a partial view that displays a numeric paging interface Like with its predecessors, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article.
