• Database vs Networking

  - by user16258

  I have completed my diploma in (IT) and now pursuing degree, i am in last semester of my B.E(I.T). I want to do specialization either in Database(oracle) or in Networking(cisco). Which one of two will be in more demand in near future, i know it's all about interest but still i would like to know your opinion. Most of people say that a network engineer is never paid as better as a programmer or a DBA, and few says they do get paid well. What would be the scope if i clear my CCNA and CCNP exams, or either OCA & OCP exams, what would be more rewarding. Also i have read somewhere that most of the task of DBA will be automated so in future demand of a DBA will reduce. I would also like to hear from Network engineers what's the scenario out there in India. Thanks

• Who organizes your Matlab code?

  - by KE

  After reading How to organize MATLAB code?, I had a follow up question. If you work in a group of Matlab programmers, who enforces the organization of the shared Matlab code and project matfiles? For example do you have a dedicated Matlab IT person, or does the most senior programmer issue guidelines that everyone must follow, or does everyone agree to follow a system? In my small group, each person has their own 'system'. Matlab code and project matfiles are either piled into a shared drive or tucked away on people's own computers. Hard to recreate work done by another person, or even to locate their code. There were lots of good suggestions on how to get organized. But it seems like someone has to make the trains run on time. Who does it in your group?

• Design patterns and multiple programming language

  - by Eduard Florinescu

  I am referring here to the design patterns found in the GOF book. First how I see it, there are a few peculiarities to design pattern and knowing multiple language knowledge, for example in Java you really need a singleton but in Python you can do without it you write a module, I saw somewhere a wiki trying to write all GOF patterns for JavaScript and the entries where empty, I guess because it might be a daunting task. If there is someone who is using design patterns and is programming in multiple programming languages supporting the OOP paradigm and can give me a hint on how should I approach design patterns that might help me in all languages I use(Java, JavaScript, Python, Ruby): Can I write good application without knowing exactly the GOF design patterns or I might need some of them which might be crucial and if yes which one, are they alternatives to GOF for specific languages, and should a programmer or a team make its own design patterns set?

• How to produce assets effectively on large Flash game projects?

  - by Antoine Lassauzay

  I have been working on Flash games professionally for two years now and somehow, having our artists producing assets the right way is one of our biggest challenge. More precisely, it is very hard to have them following any kind of structure and/or standards, nor taking into consideration performance. I would say also the most of our issues concerns UI and related animations. Our current workflow is (on a Facebook hidden object game) : Artists produce PSD and animate prototypes in Flash Artists re-organize their FLA files to be a bit more "programmer friendly" Programmers retouches assets until they have the right structure and export classes inside a SWC, from Flash Programmers try to improve performances, sometimes degrading the quality of game graphics Our main idea is to hire somebody dedicated to prepare assets for programmers but I am really looking forward to improving the pipeline. I was wondering if you guys have tips of any kind to improve this workflow, whether it be team organization, training, tools or tips with Flash. Any explanation on your asset pipeline is well appreciated too.

• Selling your services when you use uncommon technologies

  - by speeder

  I took a look in Stackoverflow most popular profiles, and then I did the same in several other sites, and then I took a look in job postings in several boards, mostly out of curiosity, because I noticed this: If you work with Java, .NET or other managed languages, or you work with stuff that is popular for web development (Ruby, JavaScript, etc...) you can get lots of points on Stackoverflow, find lots of jobs and clients, find forums, friends, colleagues, etc... But how a programmer of uncommon languages (Lua, pure C, Lisp, D, ADA, Haskell, etc...) find information, sell his services, and so on? EDIT: This also applies to fields: You work with web, corporate software, database, etc... it is great... You dislike those previous 3, noone ever will hire your services...

• What would be a best way to code a rudimentary LIMS?

  - by Sam

  Hi, I hope that I am asking the right question at right place. If not, please do not hesitate to point me to the right place. I am working in a laboratory, where computers/programming/programmers are all used only as support. But I believe that we need better information organization and management. Given the diverse information generated in the lab I believe that we need some sort of Laboratory Information Management System. Is there a good starting point to do this? I am myself not a trained programmer. I can code reasonably well in python and R, and if necessary I can learn MySql, php.

• I need help with some terminology

  - by Christine

  I'm not a programmer; I'm a freelance writer and researcher. I have a client who'd looking for stats on certain "threats" to the apps market. One of them is cowboy coding. (I know what that means; that's not my question.) Specifically, he wants to see numbers regarding how many apps have failed/crashed/removed because of errors made by, in essence, sloppy coding. (I'm not here to debate the merits of cowboy coding, and whether or not it is sloppy; work with me here.) I've used every possible search term/phrase I can think of, but I can't find any hard numbers, just anecdotal evidence. Have any of you seen any reports that have this kind of data?

• How can an experienced web developer transition to desktop development?

  - by Craige

  I'm a web developer, first and foremost. I've been programming for 5 or 6 years now, all of which has been web-based. I'm good at my job, both specifically as a web developer and as a programmer in general. I have decided recently that I would like to learn some desktop programming to to beef up my skill-set. My question is this: How can an experienced web developer transition to desktop development? To elaborate: I have always been a web-developer, and I can design and build web-applications without any problem. When it comes to sitting down with a to learn some desktop oriented programming, my problem isn't with any of the technical matters, but rather coming up with an idea to program. I draw a blank.

• Why is there still so much offer for Perl programmers?

  - by user491444

  A quick search on monster.com on different scripting languages resulted on Perl having much more job opportunities than Python and Ruby (in Europe, I didn't check for the rest of the world), and since I'm just a newbie programmer I was wondering why is this? I've read everywhere that Python and Ruby are much better languages, and much more organized. Having coded in python and php myself, Perl's code seems so alien to me. Anyways, sorry for my poor English, it's my second language, and this is not a critique on the Perl language, I was just wondering whether it's a good idea to learn it at this point or not.

• Why no client-side HTML include tag?

  - by Xepoch

  I had a question posed to me the other day by another programmer. I remember (a very long time ago) wondering the very same. Why was a browser-side include tag never considered? Or was it? Specifically with a tag that instructed the browser to include additional HTML from other sources. e.g. <include src="http://server/foo/bar.html">. Many folks will make javascript calls and fill innerHTML to accomplish the same, when the same outside a the javascript engine could be accomplished by the browser. It would have been painful to have nested <HTML>s <BODY>s (i.e.) but we have to consider that aspect anywhere anyway.

• What is the greatest design flaw you have faced in any programming language?

  - by Anto

  All programming languages are having their design flaws simply because not a single language can be perfect, just as with most (all?) other things. That aside, which design fault in a programming language has annoyed you the most through your history as a programmer? Note that if a language is "bad" just because it isn't designed for a specific thing isn't a design flaw, but a feature of design, so don't list such annoyances of languages. If a language is illsuited for what it is designed for, that is of course a flaw in the design. Implementation specific things and under the hood things do not count either.

• Are 'edited by' inline comments the norm in shops which use revision control?

  - by Joshua Smith

  The senior dev in our shop insists that whenever code is modified, the programmer responsible should add an inline comment stating what he did. These comments usually look like // YYYY-MM-DD <User ID> Added this IF block per bug 1234. We use TFS for revision control, and it seems to me that comments of this sort are much more appropriate as check-in notes rather than inline noise. TFS even allows you to associate a check-in with one or more bugs. Some of our older, often-modified class files look like they have a comment-to-LOC ratio approaching 1:1. To my eyes, these comments make the code harder to read and add zero value. Is this a standard (or at least common) practice in other shops?

• Pair programming business logic with a non-IT person

  - by user1598390

  Have you have any experience in which a non-IT person works with a programmer during the coding process? It's like pair programming, but one person is a non-IT person that knows a lot about the business, maybe a process engineer with math background who knows how things are calculated and can understand non-idiomatic, procedural code. I've found that some procedural, domain-specific languages like PL/SQL are quite understandable by non-IT engineers. These person end up being co-authors of the code and guarantee the correctness of formulas, factors etc. I've found this kind of pair programming quite productive, this kind of engineer user feel they are also "owners" and "authors" of the code and help minimize misunderstanding in the communication process. They even help design the test cases. Is this practice common ? Does it have a name ? Have you had similar experiences ?

• Why don't more games use vector art?

  - by Parris

  It would seem to me that vector art is more efficient in terms of resources/scalability; however, in most cases I have seen artists using bitmap/rasterized art. Is this a limitation put on the artists by the game programmers/designers? As a programmer I think vector art would be more ideal, since it allows for scaling up resolution without having to recreate the art, creating really large graphics or causing graphics to become blurry. The questions: why aren't more people using SVG/AI to create 2D game art? Would it actually be preferred (and who prefers it)? Are bitmap graphics a standard or a limitation (or maybe neither)? Background: I am working on an engine, and I had some kinda cool ideas for vector based graphics; however, I don't want to piss off artists in the future. I guess this is more a question centered around pragmatism and developing games.

• Is it necessary to read every single byte to check if a copied file is identical to the original?

  - by Koen027

  I recently learned of a program called Total Commander. It's a Windows Explorer replacement and has its own stuff to copy files. To check whether the files are identical, instead of calculation a CRC, it literally checks every single byte, one at a time, on both the original and the copy. My question is: Is this necessary? Can CRC or any other such technique go wrong? Should you, as a programmer, try and implement this perfect but slow system, or is it too extreme?

• Can a loosely typed language be considered true object oriented?

  - by user61852

  Can a loosely typed programming language like PHP be really considered object oriented? I mean, the methods don't have returning types and method parameters has no declared type either. Doesn't class design require methods to have a return type? Don't methods signatures have specifically-typed parameters? How can OOP techniques help you code in PHP if you always have to check the types of parameters received because the language doesn't enforce types? Please, if I'm wrong, explain it to me. When you design things using UML, then code classes in PHP with no return-typed methods and no-type parameters... Is the code really compliant with the UML design? You spend time designing the architecture of your software, then the compiler doesn't force the programmer to follow your design while coding, letting he/she assign any object variable to any other variable with no "type-mismatch" warning.

• Why is design by contract considered an alternative to the pseudo programming process?

  - by zoopp

  Right now I'm reading Code Complete by Steve McConnell and in chapter 9 he talks about the Pseudo Programming Process (PPP). From what I've understood, the PPP is a way of programming in which the programmer first writes the pseudo code for the routine he's working on, then refines it up to the point where pretty much each pseudo code line can be implemented in 1-3 lines of code, then writes the code in the designated programming language and finally the pseudo code is saved as comments for the purpose of documenting the routine. In chapter 9.4 the author mentions alternatives to the PPP, one of which is 'design by contract'. In design by contract you basically assert preconditions and postconditions of each routine. Now why would that be considered an alternative? To me it seems obvious that I should use both techniques at the same time and not chose one over the other.

• Testing on Device Other Than the Known Brand Question (Local and Imported Phone Question)

  - by David Dimalanta

  I have a question. When testing a device by using Eclipse, it's easy to install and add device software with these specific brands commonly used in game testing like Samsung, Google, T-Mobile, and HTC; according to the Android Developers website. What if I'm using other brands that runs on Android to test the program via Eclipse (i.e. MyPhone, Starmobile), what should I look for to download in order to enable testing phones that those brands are using other than the brands that are known and commonly used: model number or simply brand? Here's some examples of these brands other than the brands we've known that runs on Android: Starmobile Engage 7 (http://www.lazada.com.ph/Starmobile-Engage-7-Android-40-4GB-with-Wi-Fi-Black-Starmobile-Mercury-B201-COMBO-39833.html/) My|Phone A898 Duo (http://www.myphone.com.ph/#!a898-duo/c1yt) Also, take note that I'm a Filipino programmer working at the Philippines to test our local smartphones for the created Android game or app. Hope you can understand me for my help.

• Better Programming By Programming Better?

  - by ahmed

  I am not convinced by the idea that developers are either born with it or they are not. Where’s the empirical evidence to support these types of claims? Can a programmer move from say the 50th to 90th percentile? However, most developers are not in the 99th or even 90th percentile (by definition), and thus still have room for improvement in programming ability, along with the important skills.The belief in innate talent is “lacking in hard evidence to substantiate it” as well.So how do I reconcile these seemingly contradictory statements? I think the lesson for software developers who wish to keep on top of their game and become experts is to keep exercising the mind via effortful studying. I read a lot technical books, but many of them aren’t making me better as a developer.

• How to document/verify consistent layering?

  - by Morten

  I have recently moved to the dark side: I am now a CUSTOMER of software development -- mainly websites. With this new role comes new concerns. As a programmer i know how solid an application becomes when it is properly layered, and I want to use this knowledge in my new job. I don't want business logic in my presentation layer, and certainly not presentation stuff in my data layer. Thus, I want to be able to demand from my supllier that they document the level of layering, and how neat and consistent the layering is. The big question is: How is the level of layering documented to me as a customer, and is that a reasonable demmand for me to have, so I don't have to look in the code (I'm not supposed to do that anymore)?

• expand window to free space on screen in kde

  - by Pascal Rosin

  I am using Kubuntu and I want to expand the current window to the free space on the screen or to say it more precisely: I want to make the current window as big as possible without overlapping new windows (windows already overlapped should be ignored). Is there a keyboard shortcut or an extension to the KDE Window management, that realizes such a shortcut or a window button? I would also appreciate a hint, how to write a script that could do this window thing on keyboard shortcut invocation. I am a programmer but don't know what the best way is to control KDE Windows via script.

• Are there examples of non CRUD approaches?

  - by Pieter B

  I'm a programmer but also have worked as an archivist. As archivist it's a lot about keeping data. I often get into arguments with colleagues when it comes to operations on data. I don't like the U and the D in CRUD too much. Rather then update a record I prefer to add a new one and have a reference to the old record. That way you build a history of changes. I also don't like deleting records but rather mark them as inactive. Is there a term for this? Basically only creating and reading data? Are there examples of this approach?
