• Should comments say WHY the program is doing what it is doing? (opinion on a dictum by the inventor of Forth)

  - by AKE

  The often provocative Chuck Moore (inventor of the Forth language) gave the following advice (paraphrasing): "Use comments sparingly. Programs are self-documenting, with a modicum of help from mnemonics. Comments should say WHAT the program is doing, not HOW." My question: Should comments say WHY the program is doing what it is doing? Update: In addition to the answers below, these two provide additional insight. Beginner's guide to writing comments? http://programmers.stackexchange.com/a/98609/62203

• When not to use Google Web Toolkit?

  - by Jas

  I'm considering use of GWT on a major in-house web app development project, namely it's major advantage in my eyes is the cross-compilation to Javascript which would (at least theoretically) help my team reduce the size of tech stack by one. However, having been burnt before (like most devs), I would like to hear from programmers who did actually use it on any problems with GWT which would hamper, or limit, it's use within a certain problem domain. When do you not recommend using GWT, and why?

• What do you call this { character?

  - by John Isaacks

  When talking to another programmer I would refer to ( and ) as parentheses. I would refer to [ and ] as brackets. What do you refer to { and } as? I checked the wikipedia article and there were several names listed: curly brackets squiggly brackets definite brackets swirly brackets birdie brackets Scottish brackets squirrelly brackets braces gullwings Is there a term commonly used within programmers to identify these characters?

• When does Information become Data? (i.e. Information wants to be free) [closed]

  - by James P. Wright

  I hear Programmers often talk about how Information Wants To Be Free which I mostly agree with, but the thing that people don't often pay attention to is that Information and Data are not the same thing. Should Data also be free? Does that mean all of you should have full access to my Social Security Number and other personal "information"? Where is the limit? If there is a limit, why do people throw this phrase around like it fits every circumstance (like this one)

• What actions should I not rely on the packaged functionality of my language for?

  - by David Peterman

  While talking with one of my coworkers, he was talking about the issues the language we used had with encryption/decryption and said that a developer should always salt their own hashes. Another example I can think of is the mysql_real_escape_string in PHP that programmers use to sanitize input data. I've heard many times that a developer should sanitize the data themselves. My question is what things should a developer always do on their own, for whatever reason, and not rely on the standard libraries packaged with a language for it?

• How important is to be able to write code like you would write prose

  - by benhowdle89

  Recently I heard of a company that, for interviews, asks potential employees to stand up and write out code on a whiteboard. Apparently that freaked alot of interviewees out. This got me thinking and even though I consider myself a reasonable programmer, I would be hard pressed to write lengthy code out without referring to previous code I had written or doing a quick Google search. How many programmers could safely say "Yes I could write all my code out just like I was writing an email"?

• What problems can arise from emulating concepts from another languages?

  - by Vandell

  I've read many times on the web that if your language doesn't support some concept, for example, object orientation, or maybe function calls, and it's considered a good practice in this other context, you should do it. The only problem I can see now is that other programmers may find your code too different than the usual, making it hard for them to program. What other problems do you think may arise from this?

• What's with the aversion to documentation in the industry?

  - by omouse

  There seems to be an aversion to writing even the most basic documentation. Our project READMEs are relatively bare. There aren't even updated lists of dependencies in the docs. Is there something I'm unaware of in the industry that makes programmers dislike writing documentation? I can type out paragraphs of docs if needed, so why are others so averse to it? More importantly, how do I convince them that writing docs will save us time and frustration in the future?

• Can you be a manager and a programmer at the same time?

  - by Pierre 303

  Managing other programmers while you are yourself a part of the programming work force. It's a very common scheme, at least in the companies I worked for. Can you be a good programmer or a good manager if you do both at the same time? I'm questioning the effectiveness of an individual that has to be in two very different roles, requiring very different skills, environment, concentration, organization, etc.

• ASP.NET book for desktop programmer. [closed]

  - by RealityDysfunction

  Fellow programmers, I have been learning C# for a while now, but my ultimate goal is to develop ASP.NET applications. A few ASP.NET books I looked at either start with absolute basics...What is C#? What is a function...or Assume that I have developed web apps in other languages like PHP...I am looking for a book that is tailored for people who already know desktop programming but wish to learn ASP.NET. Did anybody come across such a book? Many Thanks.

• What is a software prototype?

  - by Stack Stock

  I understand this site is for programmers, and i have to ask specific coding question. I am doing a software engineering degree and i have been asked to reference at-least 7 books in my definition of prototyping. The best place to ask is here because most of you have probably read books on this and would be able to recommend books to me. I dont mind buying them from Amazon so if you could some books for me that define prototyping or a prototype i would really appreciate it.

• What are some good debugging techniques [closed]

  - by Brad Bruce

  I frequently run into situations where I'm working with other programmers, helping out with debugging issues. Over the years, I've acquired my own techniques for logically breaking down a problem and tracing through it. I see several others who are great at writing programs, but freeze up when debugging. Are there any good resources I can point people to that describe some good debugging techniques?

• What legal considerations do I need to have when programming?

  - by JustJohn

  Recently I worked with a group to create a logging system for tutoring labs to track Tutor hours, and usage of the labs. We had to change the design a fair amount to be in compliance with FERPA. My question stems from the curiosity that in my course of study there has never been a real mention of how people in this field have to deal with complying with the law in their work. So I would like to know how much programmers have to consider the law in the work they do.

• Trainee programs for foreigner in EU [closed]

  - by user63970

  Maybe this is the wrong site for asking that, but I didn't find better. I heard a lot about programs for young IT specialists in EU from other countries, my residence is Ukraine. We have several organizations that provide info about them, but you must pay quite a lot for them to only show you the list of vacancies. Maybe someone knows about companies in EU that are willing to take young programmers for trainee or junior vacancies from non-EU countries? I am interested in C++ development.

• Android/Java learning resources for an experienced Objective C programmer?

  - by hotpaw2

  What resources are available for an experienced Objective C programmer to quickly and efficiently learn and get up to speed with Java, the Android SDK API's and Eclipse IDE? There seems to be at least one book and several web sites for experienced Java programmers who want to learn native Objective C programming, iOS UIKit and Xcode, but who don't want to waste time with a lot of basic programming concepts that an experienced Java programmer usually already knows. What are the available advanced educational materials for the inverse direction?

• Is Life Better as a Manager? [closed]

  - by foreyez

  I've read similar posts to this, but I want to specifically target this question. This is mainly geared towards Developers that became Managers in their career. I want to know if you think being a Manager is a funner/better/more interesting life than a programmer's. (Or would you rather go back to being a programmer, if so why?) Thanks Note: Programmers that are not actively managing others please don't answer this question.

• Will low level programms become obsolete once the "post-performance" world arives? [closed]

  - by nbv4

  With the new iPhone 5 being as powerful as the supercomputers of the 1980s, its only a matter of time when the latest phones will be powerful enough to run a twitter-scale web application from within my pocket. When that time comes, performance will no longer be something programmers need to care about. Will low level languages still have a place? Or will everyone move to dynamic languages like Python?

• Strict C++ guidelines [on hold]

  - by Banex

  Some time ago I ran across an answer here on Programmers that linked a Wikipedia page about some strict guidelines for C++. The only thing I remember is that it didn't allow exceptions and was in general very strict, and that it was used in many workplaces where most C++ features are not considered useful, or are not available (embedded systems, etc). I'd like to know the name of those guidelines, as I searched the whole internet without finding it.

• Office lights on or off in programming department? How to decide? [closed]

  - by smp7d

  At my company, the programmers who sit in the same area are constantly fighting over whether the lights stay on or off. Because there is no official policy it makes it a particularly sticky situation. We are a typical cube-farm and we have those typical cube-farm fluorescent lights and smaller ones at our desks. With the lights off, it is difficult to read and you would probably need to turn on your desk light (which some people do anyway). All programmers in our department do most of their reading on their monitor because of the nature of our business. Some feel that we should have a vote to decide whether the lights stay on or off. A couple who prefer 'lights on' feel that the vote would need to be unanimous to turn them off as having them on is the more natural office setting. Those who want them off point out that all other departments keep their lights off. I have heard all of the arguments: -Fluorescent lights cause eye strain -Reading in dark causes eye strain -The desk lights can be used if light is needed -People from other departments feel uncomfortable approaching us in the "dark" -The monitors are harder to see in the light ... Right now, some of the developers turn off the lights and some turn them on. It really just depends who last walked by the switch. I am a bit sick of the controversy as it feels a bit childish at the moment. I'm tired of hearing about it and I'm tired of having to talk about it. I tried to help them decide but as I explained, voting wasn't enough. Do other programming departments have this same argument? What is the standard or traditionally accepted option in a programming area? Are there any good reasons for one way or the other outside of preference? How can we decide fairly? EDIT Just a little more info... We do not have clients/visitors come into our office. We do have windows and hall lights that make our environment plenty bearable with the lights off. It kind of resembles a meeting room that has the lights off during a powerpoint presentation.

• what is the task of a coach in acm programming contests?

  - by Layla

  In the university that I am working they have decided to participate in the ACM regionals for the first time, they would like to appoint me like a coach. I have never been into that situation before and have not found so much information about it, so what is the real work of a coach in those contests? Sometimes I have found experienced programmers like coaches, but others are just people with no so good programming skills; so what is all about?

• What's the name for a bug that suddenly breaks things but has always been present?

  - by splattered bits

  We had a failure in our software today and after investigating discovered that the failure should have been occurring for weeks, but it waited until this morning to rear its ugly head. Is there an accepted name for such a bug that I can use when referring to it with other programmers? The closest I could find was a Schrödinbug, but I'm don't think it applies, since nobody was inspecting any code. The bug was just lying in wait.

• What non-computer based programming tools do you consider invaluable? [closed]

  - by Schroedinger

  Possible Duplicate: What physical tools do you find useful to work as a programmer? I'm talking about things like whiteboards for process planning, paper for mapping out logic flows, particular books that you've found relevant, things in your workspace that help you think and process what you're working on and how to attack problems. I'm starting out in a corporate environment and want to have an understanding of what tools really work for other programmers to help them work through their problems and solutions.

• Where can I obtain a first-generation copy of the classic “Sorting out Sorting”?

  - by TML

  I cannot even figure out who made it - even the IMDB page is mostly blank, and Wikipedia does not seem to have any information about it. For such a useful film in CompSci, it strikes me as odd that the only meaningful Internet presence I can find are horrible quality copies or excerpts on YouTube. [Note: SO claims this question was migrated to here, but the URL they provide gives a 404, and I can't find it by searching Programmers.SE, so I'm re-asking...]

• What is the Best Practice for creating a secure login in a client - server appllication?

  - by Karamafrooz

  It's been a while I have been thinking on what could be the best scenario for creating a secure login in a client-server application running on internet or any other networks ! So I became with the idea to ask this question on programmers and I hope that this question will make awareness of new aspects of threads and security here by some kind of brain storming , I am really interested in good and new anseawres . Thanks in advance for your participation .
