• 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 ?

• Is it good practice to analyse who introduced each bug?

  - by Michal Czardybon

  I used to analyse performance of programmers in my team by looking at the issues they have closed. Many of the issues are of course bugs. And here another important performance aspect comes - who introduced the bugs. I am wondering, if creating a custom field in the issue tracking system "Blamed" for reporting the person who generated the problem, is a good practice. One one hand it seems ok to me to promote personal responsibility for quality and this could reduce the additional work we have due to careless programming. On the other hand this is negative, things are sometimes vague and sometimes there is a reason such us "this thing had to be done very quickly due to a client's...". What to you think?

• Should I add old code into my repository?

  - by Ben Brocka

  I've got an SVN repository of a PHP site and the last programmer didn't use source control properly. As a result, only code since I started working here is in the Repo. I have a bunch of old copies of the full code base saved in files as "backups" but they're not in source control. I don't know why most of the copies were saved nor do I have any reasonable way to tag them to a version number. Due to upgrades to the frameworks and database drivers involved, the old code is quite defunct; it no longer works on the current server config. However, the previous programmers had some...unique...logic, so I hate to be completely without old copies to refer to what on earth they were doing. Should I keep this stuff in version control? How? Wall off the old code in separate Tags/branches?

• Why is implementing copy-paste in a touch screen based smartphone such a big deal?

  - by EpsilonVector

  I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

• Web development tools/approaches?

  - by Clinton

  My day job involves a bit of programming, but I've recently been attempting some web development for personal reasons. I've got Drupal up and running and done basic things like add new content (i.e. heading and text) and add modules and themes, but I'm not sure how to approach actually designing pages. When I mucked around with webpages 15 years ago, it was just a mixture of HTML, CSS and Javascript, generally written with a text editor. Have things changed, or is this the way I'd make a Drupal page today? If it makes a difference, in my case the page's I want to design simply have static content, but I'd like them to be easily updatable.

• How to design network protocols

  - by dandroid

  As a programmer, you work on your software design skills. You learn about things such as modularity and reusability and how you can achieve them in code. There's plenty of literature on the subject and engineers talk about it all the time. What about if you want to design network protocols? How do you judge that protocol X is badly designed while Y is well designed? (eg. in programming you are often pointed out to a well-written piece of code in order to learn from it - what is the equivalent for network protocols?) For example, suppose I want to design a P2P protocol similar to BitTorrent or I want to make a better version of the Socks protocol. How would I go about doing a good job on this? Thanks!

• Recommended language and IDE for simple linux application [on hold]

  - by niklon

  I want to write a simple program on Debian with Gnome. Application will act as a side bar, giving simple information on online servers statuses. I preferably have a black transparent background(Terminal-like). I'm asking this question because I was previously writing programs in .NET C# for myself, and now I don't want to get to Mono, but something more conventional. What language should I choose for this task? What would be the recommended way to do it?(eg. what IDE)

• LWJGL - OpenGL - Texture shading

  - by Trixmix

  I want to use LWJGL to create a shader that all it does is change the color of the given texture. For example I tell it to draw the letter A using a sprite sheet then I can tell the shader to draw the letter in a certain color. How would you do something like this without needed to create different colored letter sprite sheets? Task for the shader: Simply change all pixels to a certain color in the texture. Input: Color , texture. Output: it draws onto the screen the new colored texture. How do i accomplish such a thing?

• User defined type for healthcare / Medical Records variable name prefixes?

  - by Peter Turner

  I was reading Code Complete regarding variable naming in trying to find an answer to this question and stumbled on a table of commonly accepted prefixes for programming word processor software. Well, I'm not a word processor software programmer, but if I was, I'd be happy to use those user defined types. Since I'm a programmer for a smallish healthcare ISV, and have no contact with the larger community of healthcare software programmers (other than the neglected and forsaken HealthCareIT.SE where I never had the chance to ask this question). I want to know if there is a coding convention for medical records. Like Patient = pnt and Chart = chrt and Medication = med or mdctn or whatever. I'm not talking full on hungarian notation, but just a standard that would fit in code complete in place of that wonderful chart of word processor UDT's which are of so little use to me.

• What is a good use case for scala?

  - by Usman Ismail

  In a current project we have setup the build so that we could mix Java and Scala. I would like to use more Scala in our code base to make the code more readable and concise. In the process also learn the language by handing over real features. So I plan to use Scala for some classes to showcase its benefits and convince other devs to look into using Scala too. For a rest based web server or a program in general what kind of code structures lend themselves to Scala's functional programming style.

• LED 49-unit Quadcopter Formation Foreshadows The Robot Takeover

  - by Jason Fitzpatrick

  Perhaps there are a few more steps between 49 semi-autonomous quadcopters doing a little aerial dancing and Skynet, but we’re awed and apprehensive at the same time. Check out the video to see them in action. The video comes to us courtesy of a German art conference, Ars Electronica, and a colloboration between two design groups Futurelab and Ascending Technologies GmbH. The above video is just their warmup routine; according to YouTube comments they’ll be uploading even more videos of the quadcopters and their synchronized night flights in the coming days.

• Liskov substitution and abstract classes / strategy pattern

  - by Kolyunya

  I'm trying to follow LSP in practical programming. And I wonder if different constructors of subclasses violate it. It would be great to hear an explanation instead of just yes/no. Thanks much! P.S. If the answer is no, how do I make different strategies with different input without violating LSP? class IStrategy { public: virtual void use() = 0; }; class FooStrategy : public IStrategy { public: FooStrategy(A a, B b) { c = /* some operations with a, b */ } virtual void use() { std::cout << c; } private: C c; }; class BarStrategy : public IStrategy { public: BarStrategy(D d, E e) { f = /* some operations with d, e */ } virtual void use() { std::cout << f; } private: F f; };

• Is true multithreading really necessary?

  - by Jonathan Graef

  So yeah, I'm creating a programming language. And the language allows multiple threads. But, all threads are synchronized with a global interpreter lock, which means only one thread is allowed to execute at a time. The only way to get the threads to switch off is to explicitly tell the current thread to wait, which allows another thread to execute. Parallel processing is of course possible by spawning multiple processes, but the variables and objects in one process cannot be accessed from another. However the language does have a fairly efficient IPC interface for communicating between processes. My question is: Would there ever be a reason to have multiple, unsynchronized threads within a single process (thus circumventing the GIL)? Why not just put thread.wait() statements in key positions in the program logic (presuming thread.wait() isn't a CPU hog, of course)? I understand that certain other languages that use a GIL have processor scheduling issues (cough Python), but they have all been resolved.

• Why would one overload the && and & operator?

  - by acidzombie24

  The same question goes for | and ||. Why would one overload or 'use' the & and && operator? The only use i thought of are Bitwise Ands for int base types (but not float/decimals) using & logical short circuit for bools/functions that return bool. Using the && operator usually. I cant think of any classes that use those operators. Absolutely none. I know a class might support + (and not '-') which combine two strings together. I seen an object such as datetime overload '-' so two dates can be subtracted to make a timespan (obviously you cant add two dates) but i never seen &, &&, | and || used. Does anyone know of a use? In any language?

• Looking for a light weight note program.

  - by Erin

  This might belongs on superuser but for me it's part of programming so i will ask it here. I find I use notepad to keep chunks of data that are important but not important enough to keep in my head. The one problem with this is I end up with a lot of files on my desktop that I don't know what they are for, or I don't save the file and my computer gets rebooted for some reason. So that big ramble leads to the question. I am looking for a note taking system that is light weight and easy to manage. I would rather it not be a huge application like onenote but if that is what you are using and is is working well for you could you explain how you are doing it? Thanks Erin.

• Evolution in coding standards, how do you deal with them?

  - by WardB

  How do you deal with evolution in the coding standards / style guide in a project for the existing code base? Let's say someone on your team discovered a better way of object instantiation in the programming language. It's not that the old way is bad or buggy, it's just that the new way is less verbose and feels much more elegant. And all team members really like it. Would you change all exisiting code? Let's say your codebase is about 500.000+ lines of code. Would you still want to change all existing code? Or would you only let new code adhere to the new standard? Basically lose consistency? How do you deal with an evolution in the coding standards on your project?

• Are there any downsides of 2 developers getting married ?

  - by simpson

  I remember that in my first year at college, the professor told us that his wife is also a software developer, and a few decades ago when there has been a tough period of 2-3 years in the software field they both had been unemployed and had experienced some hard times. Of course I am not asking about this economic downside, as it is a general conclusion for a family working in the same field, and is not related specifically to programming. I am asking about any other possible downsides of a family where both people are programmers. To all developers married to developers - I am not asking if it is "horrible" or something like that, of course it's not, just if there are any specific issues (all kinds of relationships has some specific issues, and at the same time are immune to others). And yes, I am asking about a male developer married to a female developer, I am clarifying to avoid jokes like "I believe that 2 developers can get married in some states" and so on :)

• Easiest solution to setup payments for a conference registration page?

  - by Keith G

  I've got a fair amount of website development experience, but I've been asked to setup a conference registration page in short order. However, I have absolutely zero experience with shopping carts, payment processing, etc. What is the absolutely quickest and easiest way to get this thing up and running? Here are my criteria: Site is currently hosted on Godaddy.com and someone has suggested using their QuickCart We cannot use any option that visits the paypal.com domain because it has been blocked my a large segment of the potential audience (on a military base). Need a $0 option for speakers Cancellations can be accepted, so maybe something that could handle that would be a bonus There is no "product" other than a confirmation that they have registered for the conference.

• Replace Libre Office with Microsoft Office

  - by user26272

  folks. I finally convinced my sister to drop Windows at her small business and go Ubuntu. She complained, though, that she does not want to use Libre Office and is willing to use Microsoft Office instead. I was like, ok, then. Then, she asked: - Libre office is the default, right? - Right. - So, if someone gives me a document, by default it will open on Libre Office. Can you make it open on Microsoft Office by default instead? So, even if I get it working via Wine, can I do what she requested or is it an impossible task?

• How to Navigate Directly From One Table to Another in Word 2013

  - by Lori Kaufman

  Jumping to a specific page in Word is a common task and easy to do using the Find and Replace dialog box. You can also use this same tab to jump from one table directly to the next table in your document. Your cursor does not have to be in a table to jump to the next table. Put the cursor in any paragraph or table and press F5 or use the Ctrl + G keystroke combination to open the Find and Replace dialog box. The Go To tab is automatically selected. Select Table from the Go to what list and click Next. The next table in your document is selected and the Find and Replace dialog box stays open.

• Realistic planetary terrain generation with weights

  - by Programmdude

  I need terrain generation for a planet. The planet will be divided up into several hundred hexes, and I need it to be realistic and based on weights. I have dabbled in terrain generation before, but nothing like this. So I figure it would be a good idea to ask the community for answers, recommended articles or the like. By realistic, I mean not just random hexes, but continent shaped things with a few islands. More desert around the equator and more ice around the poles. I also have two weights I need to base it around: ice percentage and water percentage. That means that around XX% of the planet will need to be water. Does anyone have any advice or places to start? Generating arbitrary terrain is easy, but something a bit more "organic" like this seems rather difficult. It also needs to be seamless. Should be obvious since it's a planet, but no harm in pointing it out.

• Windows Phone 7 dev: C# or silverlight for a simple app?

  - by OneWorld

  I'm about to hire a programmer to develop Windows Phone 7 apps. The current app that shall be developed is quite simple. The app will download content from a Web-API. There are two lists to select content. There is a single item content page. Users can rate the content and upload photos. The screens will be produced by our artist. I am pretty sure that most of the available programmers haven't touched WP7 development yet. Now the questions are: What technology is suitable for this kind of app? What technology requires less research, learning and production time? Do you already have experience of limitations of silverlight compared to C#? (I am also thinking of future projects) My guess is that silverlight programmers are more experienced in UI programming than C# coders. Do you feel the same way?
