• Layering Design Pattern in Java clean code style

  - by zeraDev

  As a Java developer, I am developing trying to use the clean code rules. But in my team we are facing a concrete problem: We have a business layer offering a service called "createObject", this service makes a lot of operation which can result to problem. E.g: parentObjectDontExist, objectAlreadyExist, dontHaveAuthorizationToCreate, operationFailed... and we want the UI using this service to display different information messages depending which error occurred. In old java dev, we should have create all signed exception type and throw it in createObject. As Clean code says, it is forbidden to use Exception for business logic AND signed exceptions are evil... Why not...But i don't know how to solved this problem and i don't want to use return code. How do you do? Thanks for youre experience return.

• What version will be chosen by MSXML2.XMLHTTP request, without version suffix? [migrated]

  - by jayarjo

  Probably every web developer is familiar with a pattern like this: var xmlHttp = null; if (window.XMLHttpRequest) { // If IE7, Mozilla, Safari, and so on: Use native object. xmlHttp = new XMLHttpRequest(); } else { if (window.ActiveXObject) { // ...otherwise, use the ActiveX control for IE5.x and IE6. xmlHttp = new ActiveXObject('MSXML2.XMLHTTP'); } } But the question is - if there are multiple MSXML versions available on the client's PC (let's say 3.0, 5.0, 6.0), which one of them will be chosen by MSXML2.XMLHTTP call (notice no version suffix at the end)? Will it be the latest or - not necessarily? And a side-question - is it possible to check which version was chosen?

• L'édition 2010 de la WWDC se tiendra du 7 au 11 juin 2010 à San Francisco, une édition qui s'adresse

  Voilà, Apple a enfin annoncé officiellement la tenue de la réunion mondiale des développeurs d'applications pour les produits Apple. Et cette édition 2010 s'adresse principalement, pour ne pas pas dire totalement aux développeurs pour iPhone OS. En effet, la toute grosse majorité des sessions et labos sont consacrées à l'iPhone OS et aux framework qu'on retrouve dans l'iPhone SDK Les rares fois où une session concerne Mac OS X, c'est pour expliquer comment configurer XCode, EDI utilisé également pour l'iPhone OS. Peut-être que l'édition 2011 sera plus axée, elle, sur Mac OS X, en mettant l'accent sur Mac OS X 10.7. Source : http://developer.apple.co...

• Is programming or computer science in general, all about algorithms?

  - by wakandan

  As a grad student, I find it more and more common for prestigious companies (like Google, Facebook, Microsoft,...) to put algorithm questions in their test and interviews. A few startups I applied to also asked about algorithms. I wonder if algorithms fluency is the most important thing for software developer in those companies? If the answer being yes, what are the best method or resources for one to learn & practice about algorithms effectively? I can't seem to get interested in solving seemingly too complicated problems found in most textbook or websites. Though easily understand basic algorithms (like quicksort, bubblesort,...), I find it immensely difficult to remember and reuse them later. Thanks. P/S: If you ask me what I like, it's building good softwares to solve users' problems innovatively. I suppose that does not necessarily mean the software has to be very complicated.

• Where to start when digging into an existing J2EE codebase?

  - by Jacob Krustchinsky

  I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

• Slow in the Application, Fast in SSMS? Understanding Performance Mysteries

  When I read various forums about SQL Server, I frequently see questions from deeply mystified posters. They have identified a slow query or stored procedure in their application. They cull the SQL batch from the application and run it in SQL Server Management Studio (SSMS) to analyse it, only to find that the response is instantaneous. At this point they are inclined to think that SQL Server is all about magic. A similar mystery is when a developer has extracted a query in his stored procedure to run it stand-alone only to find that it runs much faster – or much slower – than inside the procedure.

But I am looking for any strategic advise experts might have to share. Trying to leverage on past experience to have a short but effective initial learning span.

• Event Handlers and Automatic Postback in ASP.NET 3.5 Web Controls

  In one of last week s tutorials Creating Database-Driven ASP.NET 3.5 Input and List Web Controls you learned how to create a dynamic input web control that instead of setting values statically stored its list and values directly from the MS SQL server 2 8 database. This tutorial is a sequel to that article. It deals mostly with the server side coding aspect of dynamic web controls. It is recommended that you read the earlier tutorial first as the Visual Web Developer Project in that tutorial will be used extensively in this article....

• How do I get Bibletime 2.91 running on 12.04?

  - by To Do

  I would like to install the latest version of Bibletime (2.9.1) on my computer because the version in the official repositories (2.8.1) has a bug with the "Mag" feature. I had installed 2.9.1 on 12.04 32 bit through one of the following ppa's: ppa:pkgcrosswire/ppa ppa:pkgcrosswire/developer-testing Now on an Ubuntu 12.04.1 64 bit, I'm getting a dependency issue. It seems that it depends on libsword8 but it should actually depend on libsword9 which is available in the repositories. See http://sword-dev.350566.n4.nabble.com/Ubuntu-12-04-td4577002.html Can someone help me install this app please? EDIT: apt-get install -f bibletime yields the following: The following packages have unmet dependencies: bibletime : Depends: libsword8 (>= 1.6.2+dfsg) but it is not installable Depends: bibletime-data (= 2.9.1-0ubuntu0~r70~precise1) but 2.9.1-1~ppa2~precise is to be installed E: Unable to correct problems, you have held broken packages.

• I need advice on how to debug a cluster

  - by alcor

  I'm the only developer of a complex critical software system, written in Visual C++ 2005. It's deployed on a classical Microsoft cluster scenario (active/passive), that has Windows Server 2003 R2. If a server A goes down, the other one (B) starts and take the ownership of its duties. You have to know that: both servers have the same Microsoft patches/fixes, same hardware, same everything. both servers use the same memory storage (a RAID-6 through fiber channel). this software has a main module who launch the peripheral modules. if a peripheral module crashes, the main module restarts it. When I switch the application in one of the two servers (let's say the B server) two of the peripheral modules of the main applications just started to crash apparently without reason about 2 seconds after the start of the peripheral module. What could I do to analyze/inspect/resolve this weird situation?

• Business Analyst vs. Architect [closed]

  - by suslik

  I'm a developer of a few years in the financial industry and will soon need to decide what career path to try and row towards. Broadly speaking I have two options: something more 'people' oriented like BAs, or keep coding and try to make more technical decisions like the Architects do where I currently work. Here are my perceptions right now: Business Analysts: get paid way more than devs once they do their job, it seems like they usually have no worries more likely to go REALLY high up in the organization (VPs, etc) Architects: things like certification matters (I see this as a con) called in when things go wrong more than anyone else (weekends & overtime) long career path to get to (dev - senior dev - team lead - architect) I would find the latter more intellectually rewarding, but when I look at it I just can't justify it in terms of lifestyle. Am I wrong / what am I missing? Can you really make a lot of money in a technical role or must you really get out of coding? Thank you for any constructive input.

• Too much to learn, dealing with overwhelming varieties of technologies [closed]

  - by zhenka

  I am about to graduate, and I am already working as a web developer in our library IT department. When I look at job postings I am absolutely overwhelmed by the sheer variety of technologies out there. Some companies care about math + algorithms + data structures. Some care about experiences in technology stack XYZ. SQL, css, html, frameworks, javascript, design patterns etc.. etc... etc... At some point I realized I just need to start at mastering a foundation to become employable at a better place and go from there. But the skill-set to get me in the doors varies and I just don't have time to learn everything. How do you deal with this issue? What is the essential stack to become employable? Say in php or ror arena. Perhaps a smarter move would be to move to a technology stack with less variety like .net?

• How to minimize the data loss when laying off a programmer?

  - by thursdaysgeek

  I was just laid off and it was the standard process that is used in the US: call the person to talk to personnel, and remove access to the network while that is going on, then have someone help pack, always have someone with the person until they are escorted from the property. That is supposed to keep an unhappy developer from deleting or damaging software or data: to mimimize data loss. However, it still results in a lot of data loss, as all of the work the programmer was working on is dropped: software not checked in is possibly lost, documents not finished are lost, releases in process are slowed down or stopped, and a huge amount of knowledge could be lost. It seems the potential data loss is more than offset by the actual data loss. How can all losses, both potential and actual, be mimimized?

In my game I have many objects for each different level which I have to load when use click on it.

• How to deal with OOP design problems in interviews?

  - by haps10

  This is a question where I seek guidance from fellow/senior developers to get into my dream company - it's a pioneer in OOP and Agile. I've already failed once to clear an interview. One part I feel most challenging is to come up with a proper Object Oriented design(classes, interfaces, methods, interactions etc.) in a very short time for certain situations like Pacman, Game Of Life and so on. As the problems are unprecedented ones - my approach is mostly to try different things and then make decisions - which they feel is not clear and not what they expect from a developer with 5+ years of experience. I've already studied a few books on patterns, OOP - it didn't help me much and I think it'll take a bit more than that. Could some one please guide on what specifically shall I practice so that I can do better at design problems as above. I want to refine my approach and have a better thought process.

• How do developers find the time to stay on top of latest technologies?

  - by u2sonderzug

  I was a freelance web developer until circa 2004 when I started going down the management route but have decided to try to get back into development again (specifically JavaScript and HTML5 web/mobile web apps) and I really get the impression to be truly good at these and similar fast moving technologies a constant amount of time is required to be set aside to invest in getting better at existing skills in addition to learning new skills. I understand right now since I am getting back into things there is a pretty steep learning curve, but seeing how good many guys are out there - the only way I see of getting up there is putting in a serious amount of time. For those working as fulltime developers, what I am trying to understand is this - on most days, how much time in the office is spent actually grinding out code compared to learning/research. I could easily spend 2-4 hours daily getting on top of the best ways to go about doing things. Do most good developers who are employed full time invest significant hours outside of work sharpening their skills? Or maybe I'm looking at all of this completely wrong?

• oDesk agency for subcontracting

  - by lorddev

  My question has to do with whether to create an oDesk agency (I've searched to verify that oDesk questions are appropriate). I have a project for which I was hired, and the client has given me authorization to subcontract a few hours of UI/UX expertise. I don't want to make the client hire the UI/UX guy directly; however, if I hire someone with my company account and then bill the client for the time, oDesk is taking 19% off the top (10% twice). I've checked their FAQ and filed a support ticket several days ago, but nobody has replied. If there's anyone who has had experience with oDesk agencies, do you think it can be handled this way? In other words, can I be the developer in my own agency while also having a UX person on the team?
