• Should a programmer take writing lessons to enhance code expressiveness?

  - by Jose Faeti

  Given that programmers are authors and write code to express abstract thoughts and concepts, and good code should be read by other programmers without difficulties and misunderstandings, should a programmer take writing lessons to write better code? Abstracting concepts and real world problems/entities is an important part of writing good code, and a good mastery of the language used for coding should allow the programmer to express his thoughts more easily, or in a better way. Besides, when trying to write or rewrite some code to make it better, much time can be spent in deciding the names for functions, variables or data structures. I think this could also help to avoid writing code with more than one meaning, often cause of misunderstanding between different programmers. Code should always express clearly its function unambiguously.

• How do I store the OAuth v1 consumer key and secret for an open source desktop Twitter client without revealing it to the user?

  - by Justin Dearing

  I want to make a thick-client, desktop, open source twitter client. I happen to be using .NET as my language and Twitterizer as my OAuth/Twitter wrapper, and my app will likely be released as open source. To get an OAuth token, four pieces of information are required: Access Token (twitter user name) Access Secret (twitter password) Consumer Key Consumer Secret The second two pieces of information are not to be shared, like a PGP private key. However, due to the way the OAuth authorization flow is designed, these need to be on the native app. Even if the application was not open source, and the consumer key/secret were encrypted, a reasonably skilled user could gain access to the consumer key/secret pair. So my question is, how do I get around this problem? What is the proper strategy for a desktop Twitter client to protect its consumer key and secret?

• How do you go about training a replacement?

  - by SnOrfus

  I recently asked about leaving a position and got a lot of great answers. One of the common threads was that being around to train the new person would be expected and could go a long way. Now considering that (I think) most people don't stay at a company for a long time after they've given notice, and it will take time for the company to interview/hire one - that leaves for a short amount of time to get someone up to speed. I've also never trained anyone before. I did a bunch of tutoring in University and College, but teaching a language/technology is far different from training someone to replace you on your job. So the question is: how do you go about training someone to replace you in a, potentially, short amount of time?

• When would I use pseudocode instead of flowchart?

  - by user1276078

  I'm a student working with various techniques of programming, and I've come across pseudocode and flowchart. I know that these are both used in order to think through the problem before actually programming, but I have a few questions with this. When would I use pseudocode to plan out and when would I use flowcharts? Or is it better to do both before actually programming. Particularly for a small arcade sort of game in JAVA since that is my next project. I've noticed that pseudocode is very similar to the actual code rather than flowcharts. Would this make pseudocoding better because you essentially copy/paste the pseudocode into your program (of course, you have to change it to fit the language. I understand that part). Is it practical to use both of these while programming? Particularly the same game mentioned earlier. Thanks.

• What are the most important concepts to understand for "fluency in developer English"?

  - by Edward Tanguay

  In April, I'm going to be giving a talk called **English 2.0 - Understanding the Language of Developers" to a group of English teachers. The purpose is in two hours to give them a quick background in key concepts so that they can better understand developer blogs and podcasts and are able to ask better questions when talking to developers. What do you think are the most important concepts to understand, concepts that developers take for granted but the general public is not familiar with? Here are a few ideas: version control abstractions pub/sub push vs. pull debugging modularity three-tier architecture class/object "spaghetti code" vs. OOP exception throwing crowd sourcing refactoring the cloud DRY - don't repeat yourself client/server unit testing designer/developer

• I can't program because old coding style. This is normal to programmers?

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: don't have comments don't have functions (50, 100, 200, 300 or more lines executed in sequence) uses a lot of if statements with a lot of paths has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) uses a language I am unfamiliar with (Visual FoxPro 8 from 2002) I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way?

• Is Java free/open source or it isn't?

  - by user1598390

  On November 13, 2006, Sun released much of Java as free and open source software, (FOSS), under the terms of the GNU General Public License (GPL). On May 8, 2007, Sun finished the process, making all of Java's core code available under free software/open-source distribution terms, aside from a small portion of code to which Sun did not hold the copyright. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) with a linking exception. Why there are still people that say Java is not open source or free as in free speech ? Am I missing something? Is Java still privative ?

• Optimize strategies for xml parsing?

  - by Future2020

  I am looking for general optimization tips and guidelines for xml parsing. One of the optimization strategies is of course selecting the "right" parser. A detailed comparison between the available parsers for ios can be found here http://www.raywenderlich.com/553/how-to-chose-the-best-xml-parser-for-your-iphone-project. However, I am currently trying to investigate general guidelines and tips on how to optimize by payloads to increase the performance as possible. This question is similar to (a question I have posted in the context of ios) but I have not got a sufficient answer. So this question is not in the context of any particular programming language.

• How to learn programming for a medium scale project form a beginner? [closed]

  - by Lin Xiangyu

  I study programming by myself.I have learn servel programming languages. but I never write a project more than 1000 lines. I know the best way to improve programming skills is practise. The problem is many books, just talk about the programming language, or talk about build a project from a high level. Fews of books will teach how to build a middle scale project. For example, I want to build a simple HTTP Server(Nor like Apache or just a simple listenr to a port), a Markdown Parser, or a download tools just like emule or wget. I don't know what to do. I may found peaces of code in the web, or found familiar project in the Github. I don't know how to read the code. I want to some tutorial that can told me how to build the project step by step, teacher me how to write thousands lines of code. Any suggest?

• "Le problème que le XML résout n'est pas difficile, et il ne le résout pas bien": que manque-t-il le plus au langage ?

  L'essence du XML : le problème qu'il résout n'est pas difficile et il ne le résout pas correctement qu'est-ce qui manque le plus au langage Normalisé par le W3C, le langage XML (Extensible Markup Language) a été largement adopté comme format d'échange de données entre différents systèmes, plateformes et organisations. Mais, le langage a quelques faiblesses qui font souvent l'objet de plusieurs discussions et de rejet par certains. « The Essence Of Xml », l'un des documents fondamentaux sur le langage écrit par Philip Wadler et Jérôme Siméon procède à une analyse de celui-ci. Selon le document, les deux propriétés clés nécessaires pour n'importe quel format sont les suivant...

• PHP developer wanting to learn python

  - by dclowd9901

  I'm pretty familiar at this point with PHP (Javascript, too), up to the point of OOP in PHP, and am looking to branch out my knowledge. I'm looking at Python next, but a lot of it is a bit alien to me as a PHP developer. I'm less concerned about learning the language itself. I'm positive there's plenty of good resources, documentation and libraries to help me get the code down. I'm less sure about the technical aspects of how to set up a dev environment, unit testing and other more mundane details that are very important, aid in rapid development, but aren't as widely covered. Are there any good resources out there for this?

• How to design software when using BDD?

  - by Léster

  I'm working on a project right now and it's my first project using BDD. Up till now, the user stories have proven themselves a very valuable weapon to understand requirements and to specify the solution in a comprehensive, easy to understand language. My question is this: now that my user stories are complete, how do I design my solution? I understand that I derive behavior tests from my user stories, and I have to do UI design, but am I supposed to use good ol' UML? I'm under the impression that when using user stories, UML is left out; is this correct? Léster

• Why use link classes in oql instead of classes that contain links

  - by Isaac

  itop abstracts its very complex database design with an object query language (oql). For this there are classes definded, like 'Ticket' and 'Server'. Now a Ticket usually is linked to a Server. In my naive way I would give the Ticket class an attribute 'affected_server_list', where I could reference the affected servers. itop does it different: neither Servers nor Tickets know of each other. Instead there is a class 'linkTicketToServer', which provides the link between the two. The first thing I noticed is that it makes oql queries more complex. So I wondered why they designed it this way. One thing that occured to me is that it allows for more flexiblity, in that I can add links without modifying the original classes. Is this allready why one would implement it this way, or are there other reasons for this kind of design?

• Is there a good book to grok C++?

  - by Paperflyer

  This question got me thinking. I would say I am a pretty experienced C++ programmer. I use it a lot at work, I had some courses on it at the university, I can understand most C++ code I find out there without problems. Other languages you can pretty much learn by using them. But every time I use a new C++ library or check out some new C++ code by someone I did not know before, I discover a new set of idioms C++ has to offer. Basically, this has lead me to believe that there is a lot of stuff in C++ that might be worth knowing but that is not easily discoverable. So, is there a good book for a somewhat experienced C++ programmer to step up the game? You know, to kind of 'get' that language the way you can 'get' Ruby or Objective-C, where everything just suddenly makes sense and you start instinctively knowing 'that C++ way of thing'?

• What tools should I consider if my aim is to make a game available to as many platforms as possible?

  - by Kenji Kina

  We're planning on developing a 2D, grid-based puzzle game, and although it's still very early in the planning stages, we'd like to make our decisions well from the beginning. Our strategy will be to make the game available to as many platforms as possible, for example PCs (Windows, Mac and/or Linux), mobile phones (iPhone and/or Android based phones), game consoles (XBLA and/or PSN) PC will have an emphasis, but I believe that's the most flexible platform so that shouldn't be a problem. So, what programming language, game engine, frameworks and all around tools would be best suited for our goal? P.S.: I'm betting a set of tools won't cover ALL of them, and that there will still be some kind of "translating" effort for some platforms, but we'd like to know what the most far reaching are.

• 2011 Chicago Code Camp

  - by Tim Murphy

  It is that time again.  Time to polish up you presentation skills on your favorite language or technology features.  The Chicago Code Camp is accepting proposals for presentations.  Show everyone in the Chicago area what you know and submit your own. I really enjoyed presenting last year and just had to submit a proposal for this year.  This time around my topic is Increasing Collaboration with Windows Phone 7, SharePoint 2010 and Office Open XML.  I had a much longer title but the site forced me to shorten it up.  I guess that is a good way to tell people not to get too wordy. If you don’t feel like presenting mark the date and come out and enjoy the company of your fellow geeks and learn about some new technologies. http://chicagocodecamp.com/ del.icio.us Tags: Chicago Code Camp,speaking,WP7,Windows Phone 7,SharePoint 2010,OOXML,Office Open XML

• Object-Oriented equivalent of LISP's progn function?

  - by Archer

  I'm currently writing a LISP parser that iterates through some AutoLISP code and does its best to make it a little easier to read (changing prefix notation to infix notation, changing setq assignments to "=" assignments, etc.) for those that aren't used to LISP code/only learned object oriented programming. While writing commands that LISP uses to add to a "library" of LISP commands, I came across the LISP command "progn". The only problem is that it looks like progn is simply executing code in a specific order and sometimes (not usually) assigning the last value to a variable. Am I incorrect in assuming that for translating progn to object-oriented understanding that I can simply forgo the progn function and print the statements that it contains? If not, what would be a good equivalent for progn in an object-oriented language?

• What are the warning signs of impending doom to watch out for on a project?

  - by ConroyP

  Having worked on a failed project is one of the few things that most programmers have in common, regardless of language used, industry or experience. These projects can be great learning experiences, soul-crushing disasters (or both!), and can occur for a multitude of reasons: upper management change of heart under-skilled / under-resourced team emergence of superior competitor during dev cycle over/under management Once you've worked on a couple of such projects, is it possible to recognise at an early stage exactly when a project is doomed to fail? For me, a big sign is having a hard & fast external deadline combined with feature creep. I've seen projects which were well planned out and proceeding right on schedule go horribly off the rails once the late feature requests started to roll in and get added to the final "deliverable". The proposers of these requests earned the nickname of Columbo, due to rarely leaving the room without asking for "just one more thing". What are the warning signs you look out for that set off the alarm bells of impending doom in your head?

• Better drivers for SiS 650/740 integrated video?

  I installed Xubuntu 10.10 on an old box today and the graphical performance is horrid. According to lspci, the video card is this: 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Device 8081 Flags: 66MHz, medium devsel, IRQ 11 BIST result: 00 Memory at f0000000 (32-bit, prefetchable) [size=128M] Memory at e7800000 (32-bit, non-prefetchable) [size=128K] I/O ports at d800 [size=128] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel modules: sisfb Is there a way to make it faster? Alternative drivers? The additional drivers tool shows nothing. I'm specifically interested in improving Java's Java2D rendering speed, because I'll be running a "stat screen" written in that language on it.

• How to shorten brain context switch delay when need to use new technology\framework?

  - by gasan

  The problem is when I have to deal with a new framework\library\language it completely slows my work process, at first it's kind of shock, you're sitting on your place about a day doing nothing surfing the net, because you simply can't do anything even read docs, then, on the second day I realize that I definitely should do something and starting read about it, then I realize that I don't understand it, then I'm reading until I got feeling that I should show some results immediately and then I'm writing the code quite fast and the job doesn't seem to be difficult. Then job is done and I won't probably return to that technology\framework for a month or a year or never at all. And I will almost certainly forget almost everything about it after a month. To illustrate by checkpoints I experience: shock, long studying times, work with the new tech briefly, never use it afterwards, then I completely forget it. So what would be the solution here?
