  • How do you explain commented-out code to a non-programmer? [closed]

    - by whirlwin
    What is the quickest and most comprehensible way to explain to a non-programmer what commented-out code is? When I mentioned it in a conversation to non-programmers, they seemed lost. Such people could for instance be graphical designers, when working on the same team to make an application. Typically I would need to mention what I will be/currently am working with during an update meeting. At first I thought about substituting commented-out with unused code. While it is true to some degree, it is also very ambiguous. If you are wondering, I am working with legacy code with commented-out code. This leads to my question: "how do you explain commented-out code to a non-programmer?"

  • Detect (and remove) non-ascii characters from files

    - by Mawg
    Something similar to this question, but that ended up with a programming answer. I am looking for a ready-made Windows application to recurse a directory tree and .. at the very least, notify me of all files which contain non-ascii characters It would be nice if it would also do any of the following (in no particular order) Let me specify which file extensions to scan Show the file contents, with the non-ascii characters highlighted Automagically remove such characters, or ... Let me launch an editor to remove them manually Know you of such a best? Thanks a 1,000,000 in advance

  • Should I be wary of signing a non-disclosure agreement with someone I just met?

    - by Thomas Levine
    tl;dr: Some guy I just met says he wants me to join his company. Before he shows me what they do, he wants me to sign a non-disclosure agreement. Is this weird? I'm traveling right now. Someone who saw me coding seemed to think I was smart or something and started talking with me. He explained that he owns a software company, told me a bit about what it does and told me that he was looking for a programmer who would work for a stake in the company. He explained that the company's product is being developed rather secretly, so he couldn't tell me much. But he did tell enough about the product to convince me that he's not completely making this up, which is a decent baseline. He suggested that he show me more of what he's been working on and, after seeing that, I decide whether I want to join. Because of the secrecy behind the product, he wants me to sign a non-disclosure agreement before we talk. I'm obviously somewhat skeptical because of the random nature by which we met. In the short term, I'm wondering if I should be wary of signing such an agreement. He said it would be easier to show me the product in person rather than over the internet, and I'm leaving town tomorrow, so I'd have to figure this out by tomorrow. If I decide to talk with him, I could decide later whether I trust that it's worth spending any time on this company. The concept of being able to avoid telling a secret seems strange to me for the same reason that things like certain aspects of copyright seem strange. Should I be wary of signing a non-disclosure agreement? Is this common practice? I don't know the details of the agreement of which he was thinking, (If I end up meeting with him, I'll of course read over the agreement before I decide whether to sign it.) so I could consider alternatives according to the aspects of the agreement. Or I could just consider the case of an especially harsh agreement. This question seems vaguely related. Do we need a non-disclosure agreement (NDA)? Thanks

  • How to explain to non-technical person why the task will take much longer then they think?

    - by Mag20
    Almost every developer has to answer questions from business side like: Why is going to take 2 days to add this simple contact form? When developer estimates this task, they may divide it into steps: make some changes to Database optimize DB changes for speed add front end HTML write server side code add validation add client side javascript use unit tests make sure SEO is setup is working implement email confirmation refactor and optimize the code for speed ... These maybe hard to explain to non-technical person, who basically sees the whole task as just putting together some HTML and creating a table to store the data. To them it could be 2 hours MAX. So is there a better way to explain why the estimate is high to non-developer?

  • GUI and non gui difference

    - by stdcinout
    hi guys as i know we have gui and non gui application today. but remember back in the old days there were many application thats kinda like half gui half not . the applications are text based and it has no GUI like what we have now if we were to use java swing library or etc. but you could pretty much select the area that you want using keyboard shortcut . pretty much looks like vim with more features. basically it is text based but not fully gui so my question is how did they do this ? to make the text output persistent and process the data as being inputed non sequentially (non gui typically inputs data non sequentially)

  • trouble accessing non-static functions from static functions in AS3

    - by Dogmatixed
    I have a class containing, among other things, a drop down menu. With the aim of saving space, and since the contents of the menu will never change, I've made a static DataProvider for the whole class that populates each instances menu. I was hoping to populate the list with actual functions like so: tmpArr.push({label:"Details...", funct:openDetailsMenu, args:""}); and then assign tmpArr to the DataProvider. Because the DataProvider is static the function that contains that code also needs to be static, but the functions in the array are non-static. At first it didn't seem like a problem, because when the user clicks on a menu item the drop down menu can call a non-static "executeFunction(funct, args)" on its parent. However, when I try to compile, the static function setting up the DataProvider it can't find the non-static functions being passed. If the compiler would just trust me the code would work fine! The simple solution is to just pass strings and use a switch statement to call functions based on that, but that's big, ugly, inelegant, and difficult to maintain, especially if something inherits from this class. The simpler solution is to just make the DataProvider non-static, but I'm wondering if anyone else has a good way of dealing with this? Making the static function able to see its non-static brethren? Thanks.

  • Using Google Talk with a non-apps, non-gmail Google account

    - by rymo
    I created a Google account with an existing e-mail address from a domain that is NOT hosted by Google. This address is not on an Apps domain and has no gmail service of any kind. Still I am able to add it as a Google account on an Android device with no problem. If the device is running Jelly Bean (where the Google Talk app allows switching between accounts) I can sign in and chat works fine. I can also sign into Talk with this account via the iGoogle home page. Now how can I use this account with a standalone chat client like iChat, Pidgin, or Empathy? It doesn't seem to work with login ID [email protected] using SSL to connect to server talk.google.com (tried ports 5222 and 5223). Are iGoogle and Android doing something magical that no other Jabber client is allowed, or am I just missing a step?

  • Non-Windows, non-Unix-like OS's?

    - by dsimcha
    Since most operating systems I've heard of besides Windows seem to derive their heritage from Unix, I've been curious whether any OS's with the following characteristics exist: Not generally considered Unix-like, i.e. wasn't designed with Unix compatibility as a primary goal, doesn't use X11 as its default GUI in the most common distributions, doesn't support Unix commands by default, etc. Not in the Windows NT family. Is a modern production operating system, not a purely legacy operating system, a research/hobby project or an OS that's still in an alpha state. Is targeted at commodity x86/x64 PC hardware.

  • How can you explain "beautiful code" to a non-programmer?

    - by Daniel Vandersluis
    When speaking with a non-programmer friend, I happened to mention the concept of "beautiful code" and she wanted to understand what that meant, but I was at a bit of a loss as to how to explain it to someone who would have no context whatsoever. When all code looks like gibberish to someone anyways, how can you explain what makes one piece of code prettier than another? Analogies could be useful too.

  • What is the rationale to non allow overloading of C++ conversions operator with non-member functio

    - by Vicente Botet Escriba
    C++0x has added explicit conversion operators, but they must always be defined as members of the Source class. The same applies to the assignment operator, it must be defined on the Target class. When the Source and Target classes of the needed conversion are independent of each other, neither the Source can define a conversion operator, neither the Target can define a constructor from a Source. Usually we get it by defining a specific function such as Target ConvertToTarget(Source& v); If C++0x allowed to overload conversion operator by non member functions we could for example define the conversion implicitly or explicitly between unrelated types. template < typename To, typename From operator To(const From& val); For example we could specialize the conversion from chrono::time_point to posix_time::ptime as follows template < class Clock, class Duration operator boost::posix_time::ptime( const boost::chrono::time_point& from) { using namespace boost; typedef chrono::time_point time_point_t; typedef chrono::nanoseconds duration_t; typedef duration_t::rep rep_t; rep_t d = chrono::duration_cast( from.time_since_epoch()).count(); rep_t sec = d/1000000000; rep_t nsec = d%1000000000; return posix_time::from_time_t(0)+ posix_time::seconds(static_cast(sec))+ posix_time::nanoseconds(nsec); } And use the conversion as any other conversion. So the question is: What is the rationale to non allow overloading of C++ conversions operator with non-member functions?

  • Understanding Node.js and concept of non-blocking I/O

    - by Saif Bechan
    Recently I became interested in using Node.js to tackle some of the parts of my web-application. I love the part that its full JavaScript and its very light weight so no use anymore to call an JavaScript-PHP call but a lighter JavaScript-JavaScript call. I however do not understand all the concepts explained. Basic concepts Now in the presentation for Node.js Ryan Dahl talks about non-blocking IO and why this is the way we need to create our programs. I can understand the theoretical concept. You just don't wait for a response, you go ahead and do other things. You make a callback for the response, and when the response arrives millions of clock-cycles later, you can fire that. If you have not already I recommend to watch this presentation. It is very easy to follow and pretty detailed. There are some nice concepts explained on how to write your code in a good manner. There are also some examples given and I am going to work with the basic example given. Examples The way we do thing now: puts("Enter your name: "); var name = gets(); puts("Name: " + name); Now the problem with this is that the code is halted at line 1. It blocks your code. The way we need to do things according to node puts("Enter your name: "); gets(function (name) { puts("Name: " + name); }); Now with this your program does not halt, because the input is a function within the output. So the programs continues to work without halting. Questions Now the basic question I have is how does this work in real-life situations. I am talking here for the use in web-applications. The application I am writing does I/O, bit is still does it in am blocking matter. I think that most of the time, if not all, you need to block, because you have to wait on what the response is you have to work with. When you need to get some information from the database, most of the time this data needs to be verified before you can further with the code. Example 1 If you take a login for example. You have to wait for the database to response to return, because you can not do anything else. I can't see a way around this without blocking. Example 2 Going back to the basic example. The use just request something from a database which does not need any verification. You still have to block because you don't have anything to do more. I can not come up with a single example where you want to do other things while you wait for the response to return. Possible answers I have read that this frees up recourses. When you program like this it takes less CPU or memory usage. So this non-blocking IO is ONLY meant to free up recourses and does not have any other practical use. Not that this is not a huge plus, freeing up recourses is always good. Yet I fail to see this as a good solution. because in both of the above examples, the program has to wait for the response of the user. Whether this is inside a function, or just inline, in my opinion there is a program that wait for input. Resources I looked at I have looked at some recourses before I posted this question. They talk a lot about the theoretical concept, which is quite clear. Yet i fail to see some real-life examples where this is makes a huge difference.

  • Can non-IT people learn and take advantage of regular expressions? [closed]

    - by user1598390
    Often times, not-IT people has to deal with massive text data, clean it, filter it, modify it. Often times normal office tools like Excel lack the tools to make complex search and replace operations on text. Could this people benefit from regexps ? Can regexp be taught to them ? Are regular expressions the exclusive domain of programmers and unix/linux technicians ? Can they be learned by non-IT people, given regexps are not a programming language? Is this a valid or achievable goal to make some users regexp-literate through appopriate training ? Have you have any experiences on this issue? and if so, have it been successful ?

  • C#.NET Forms programing - Modal and Non-Modal forms problem

    - by Povilas
    Hello, I have a problem with modality of the forms under C#.NET. Let's say I have main form #0 (see the image below). This form represents main application form, where user can perform various operations. However, from time to time, there is a need to open additional non-modal form to perform additional main application functionality supporting tasks. Let's say this is form #1 in the image. On this #1 form there might be opened few additional modal forms on top of each other (#2 form in the image), and at the end, there is a progress dialog showing a long operation progress and status, which might take from few minutes up to few hours. The problem is that the main form #0 is not responsive until you close all modal forms (#2 in the image). I need that the main form #0 would be operational in this situation. However, if you open a non-modal form in form #2, you can operate with both modal #2 form and newly created non modal form. I need the same behavior between the main form #0 and form #1 with all its child forms. Is it possible? Or am I doing something wrong? Maybe there is some kind of workaround, I really would not like to change all ShowDialog calls to ShowDialog... Thanks, Povilas

  • Non Blocking Keyboard on WinCE accessing the virtual keyboard

    - by Jan H.
    Hello Guys, I am desperately looking for a solution that enables me to read keyboard events in a non blocking way. These Keyboard events are generated by a VIRTUAL KEYBOARD that comes with the WinCE device. I have a console application running in C++, where the user is asked to navigate via 'ESC', 'U' and other characters through the menu. I first tried to use fread and stdin and realised that it is blocking call and waits for a carriage return. Then I tried to hook up to the windows message WM_KEYUP, but I never recieve this windows message. Furthermore I tried to use QtGUI together with the event QKeyEvent, but I never recieve any event. I wonder if it is in general possible to recieve non-blocking keyboard events on a WinCE device. I would be glad if you have any suggestions! Cheers, Jan

  • Convert non-breaking spaces to spaces in Ruby

    - by CoolAJ86
    I have cases where user-entered data from an html textarea or input is sometimes sent with \u00a0 (non-breaking spaces) instead of spaces when encoded as utf-8 json. I believe that to be a bug in Firefox, as I know that the user isn't intentionally putting in non-breaking spaces instead of spaces. There are also two bugs in Ruby, one of which can be used to combat the other. For whatever reason \s doesn't match \u00a0 However [^[:print:]] (which definitely should not match) and \xC2\xA0 both will match, but I consider those to be less-than-ideal ways to deal with the issue. Are there other recommendations for getting around this issue?
