  • Which tool to create a sitemap to plan a future site?

    - by peterpurzelbaum
    I'd like to create a sitemap to plan a future site, and I'm looking for a tool to do it. I'd like to create a list of all articles first. Then a hierachy. Then I'd like to put the articles on several places in the hierachy. I should be able to put one article at different places. I'd like to have the ability to mark the articles in different colors whether they should come into the first version of the website or later.

  • What software analogies have helped you?

    - by Galwegian
    I have often enjoyed the use of analogies in understanding a software scenario or problem. For example, to understand the concept of public key encryption, the 'locked mailbox' analogy or similar is often used as an aid: An analogy for public-key encryption is that of a locked mailbox with a mail slot. The mail slot is exposed and accessible to the public; its location (the street address) is in essence the public key. Anyone knowing the street address can go to the door and drop a written message through the slot; however, only the person who possesses the key can open the mailbox and read the message. My question is: What analogies have you used or heard of in your career that have given you that "Eureka" moment with a complex concept? EDIT: If you have a good one, don't just state the name, please share with the group!

  • CodeRush Tricks of the Trade

    - by dr. evil
    I was using CodeRush quite while ago and now I'm planning to use it again. I've install the trial but I forgot all cool features except Alt + Home (drop a marker). And when you don't know some cool tricks it's really like burning money (since it's not cheap for personal use) What do you like about it? What are your best features? My best feature is marker: Alt + Home (and use escape to go back) P.S Dear Devxpress, if you think I helped you by asking this question I can accept some donations, a free license of CodeRush would be nice! Currently What I like most ps/pi etc. shortcut to create properties cc to create constructors pressing tab to navigate between the references F12 to find references in new cool window Ctrl + Shift + . for recent files Ctrl + Shift + Q for jumping to any function / class fe/fi for "for loops"

  • What are my tool options to prototype a 2D online multiplayer game?

    - by Asher Einhorn
    I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun. EDIT - doesn't unity have some inbuilt networking stuff in it?

  • Hidden Features and Dark Corners of STL?

    - by Andrei
    C++ developers, all know the basics of C++: Declarations, conditionals, loops, operators, etc. Some of us even mastered the stuff like templates, object model, complex I/O, etc. But what are the most hidden features or tricks or dark corners of C++/STL that even C++ fans, addicts, and experts barely know? I am talking about a seasoned C++ programmer (be she/he a developer, student, fan, all three, etc), who thinks (s)he knows something 99% of us never heard or dreamed about. Something that not only makes his/her work easier, but also cool and hackish. After all, C++ is one of the most used programming languages in the world, thus it should have intricacies that only a few privileged know about and want to share with us. Boost is welcome too! One per post with an example please P.S Examples are important for other developers to copy and paste!

  • What are some programming questions (or mistakes) you get wrong only as you get better?

    - by BlueRaja
    In programming, as many professions, there are mistakes you'll make now that you may not have made as a beginner. For instance, consider pointers: In C++, is there any difference between arrays and pointers? The beginner will say yes, they are two completely different concepts, and treat them as such. The intermediate programmer (having learned that arrays are pointers internally) will tell you no, they are the same thing, and may miss some crucial bugs by interchanging them all willy-nilly. The expert, however, will again say they are different things (ex. see here or here). What other questions/mistakes are like this?

  • How to Convert arrays or SimpleXML-Objects into an XML-String

    - by streetparade
    I want to create a xml from a given string, i have a function but i didn't wrote it.It seems a bit cryptical too. Can please some one review it and give me some Ideas, how it could be written clearer for everybody? /** * Converts arrays or SimpleXML-Objects into an XML-String * @params mixed Accepts an array or xml string with data to Post * @params integer DO NOT PROVIDE. Internal Usage for recursion only */ private function mixedDataToXML($data, $level = 1) { if(!$data){ return FALSE; } if(is_array($data)) { $xml = ''; if ($level==1) { $xml .= '<?xml version="1.0" encoding="ISO-8859-1"?>'."\n"; } foreach ($data as $key => $value) { $key = strtolower($key); if (is_array($value)) { $multi_tags = false; foreach($value as $key2=>$value2) { if (is_array($value2)) { $xml .= str_repeat("\t",$level)."<$key>\n"; $xml .= $this->mixedDataToXML($value2, $level+1); $xml .= str_repeat("\t",$level)."</$key>\n"; $multi_tags = true; } else { if (trim($value2)!='') { if (htmlspecialchars($value2)!=$value2) { $xml .= str_repeat("\t",$level). "<$key><![CDATA[$value2]]>". "</$key>\n"; } else { $xml .= str_repeat("\t",$level).

  • C++: select argmax over vector of classes w.r.t. arbitrary expression

    - by karpathy
    Hello, I have trouble describing my problem so I'll give an example: I have a class description that has a couple of variables in it, for example: class A{ float a, b, c, d; } Now, I maintain a vector<A> that contains many of these classes. What I need to do very very often is to find the object inside this vector that satisfies that one of it's parameters is maximal w.r.t to the others. i.e code looks something like: int maxi=-1; float maxa=-1000; for(int i=0;i<vec.size();i++){ res= vec[i].a; if(res > maxa) { maxa= res; maxi=i; } } return vec[maxi]; However, sometimes I need to find class with maximal a, sometimes with maximal b, sometimes the class with maximal 0.8*a + 0.2*b, sometimes I want a maximal a*VAR + b, where VAR is some variable that is assigned in front, etc. In other words, I need to evaluate an expression for every class, and take the max. I find myself copy-pasting this everywhere, and only changing the single line that defines res. What makes it even more complicated is that even the name of the vector changes. Sometimes it's vec, sometimes it can be something else. I have many vectors that contain A's. This could be changed if this makes the problem too hard. Is there some nice way to avoid this insanity in C++? What's the neatest way to handle this? Thank you!

  • Fast dot product for a very special case

    - by psihodelia
    Given a vector X of size L, where every scalar element of X is from a binary set {0,1}, it is to find a dot product z=dot(X,Y) if vector Y of size L consists of the integer-valued elements. I suggest, there must exist a very fast way to do it. Let's say we have L=4; X[L]={1, 0, 0, 1}; Y[L]={-4, 2, 1, 0} and we have to find z=X[0]*Y[0] + X[1]*Y[1] + X[2]*Y[2] + X[3]*Y[3] (which in this case will give us -4). It is obvious that X can be represented using binary digits, e.g. an integer type int32 for L=32. Then, all what we have to do is to find a dot product of this integer with an array of 32 integers. Do you have any idea or suggestions how to do it very fast?

  • Navigating through code with keyboard shortcuts

    - by MarceloRamires
    I'm starting to feel the need to run fastly through code with keyboard shortcuts, to arrive faster where I want to make any changes (avoiding use of mouse or long times holding [up], [left], [right] and [down]). I'm already using some: [home] - first position in current line [end] - last position in current line [ctrl] + [home] - first line of the entire code [ctrl] + [end] - last line of the entire code [pageup] - same vertical position, one screen above [pagedown] - same vertical position, one screen below [ctrl] + [pageup] - first line in current screen [ctrl] + [end] - last line in current screen [ctrl] + [left/right] - skipping word per word What have you got ? I use Visual Studio. (but I'm open to any answer, as I maybe can use others soon) obs: I've searched through stackoverflow and didn't find a nice question with this content, nor a list of keyboard code searching. If it's repeated, I'm sorry for not finding it, I'm here in my best intentions. This question is NOT about any shortcuts, and not only about visual studio, it's about running through code with shortcuts. Answers that suit the question so far: [Ctrl] + [-] - jumps to last cursor position [Ctrl] + [F3] - Jumps to next occurance of the word the curson is in [Shift] + [F3] - Same as the above, backwards. [F12] - Goes to definition of method/variable the cursor is in [Ctrl] + [ ] ] - Jumps to matching brace and select I'll ad more as there are answers.

  • What factors influence you to try out a new framework or tool?

    - by VirtuosiMedia
    I'm in the process of putting the final touches on an open-source framework that I hope to release in the next few months. It's something that I'd like to develop a community for and so I'm curious about what factors influence your decision to use a new framework or tool and why. Some of the specific things I'd like to know more about (feel free to add to this): Types of documentation/tutorials/instruction Community support (comments/forum) Updates (blog/social media/feeds) Look and feel of the project website design White papers/testimonials A big feature list Community size Tools Ability to contribute Project test coverage (stability/security) Level of buzz (recommended by friends or around the web) Convincing marketing copy Ideally, I'd like to have all of the above, but what specific features/qualities will carry greater weight in getting programmers to adopt something new? What says, 'This is a professional-grade project,' and what are red flags that keep you from trying it out?

  • Microsoft Security Removal Tool détecte et éradique Renocide grâce à une mise à jour, le ver serait la quatrième plus grandes menaces actuelles

    Microsoft Security Removal Tool détecte et éradique Renocide Avec une mise à jour, le ver serait la quatrième plus grandes menaces actuelles Microsoft met en garde les utilisateurs de Windows contre le malware Win32/Renocide. Win32/Renocide est une famille de vers qui se propagent via les disques amovibles, les stockages locaux et les réseaux en utilisant les applications de partage de fichiers. Une fois installé, le malware crée des clones de lui-même en utilisant des noms de fichiers différents. Il est qualifié de ver « backdoor » (portes dérobées) et permet à un pirate distant d'exécuter des commandes sur le poste infecté pour télécharger d'autres programmes malveillants. Renoci...

  • Best anti boss tricks to hide your private page navigation from your desktop.

    - by systempuntoout
    This question is slightly related to programming and it's kinda lame, i know; but i saw many funny things in these years and i'm looking for new tricks from you. I'm talking about methods to fast-hide\camouflage not job related web pages on your desktop when boss arrives like a ghost\ninja behind your shoulders. I know how much can be frustrating, programming hard for ten hours and then been caught by your boss watching XKCD during a 2 minutes break. I think the most common anti boss trick is the evergreen CTRL+TAB, but you have to be fast and your left hand has to be near the keyboard. I saw pitch black brightness on Lcd (how can you pretend to program on that?) or custom sized browser to fit a little space just below the IDE. My favourite one at the moment is using fire gesture plugin with FF; with a micro gesture you can hide FF to your tray in a blink of an eye. Do you have any trick to share?

  • What is the best tool to sync browser passwords and bookmarks?

    - by jgbelacqua
    Sadly, everything I've tried so far has been painful to manage between two computers, (even between different browsers on the same computer). So, right now I have different aggregations of bookmarks passwords in xmarks, delicious, google bookmarks, firefox sync, text files, and in figaro password manager (fpm2). I've also tried to use bindwood in the past. What I would like to do is merge all bookmarks and passwords into some solution that actually works either with tools available under Ubuntu, or with a browser-based tool (addon/plugin/extension) which works between between google-chrome/chromium, and firefox. It would be ideal if there was an ability to send and store passwords encrypted (if not on my own server). Whatever the method, I need the ability to have import from existing sources. (It doesn't have to be pretty, just repeatable.) It's possible that some things I've ruled out are now workable (e.g., xmarks broke for me at one point because I hit their bookmark limit for the server/account, and bindwood, firefox sync were firefox only).

  • Should I use my models in a library?

    - by Piers
    I've got my auth library in codeigniter which accesses the database to check to see if the email/password combination is correct. If I'm sticking to the MVC practice, should I move the function that interacts with the database to my model, or is it best practice to leave it where it is so I can use it in the future? Doesn't make much difference to me, other than the fact I'd have to re-write the library and create the function in my model, but if that's the way it should be then so be it.

  • Can I use SQL to update multiple rows with multiple values from another table?

    - by stu
    I've got a one to many table with ids and traits for those users. I want to copy one user's settings to another. userid trait onoff ------ ----- ----- 1 1 on 1 2 on 1 3 on 1 4 on 2 1 off 2 2 off 2 3 off 2 4 off So I want to copy the onoff values from user 1 to 2, so that user2 has everything on when I'm done. update table set onoff = (select onoff from table where userid=1) where userid=2 that's the basic idea, but obviously doesn't work. I imagine I want the server to think in terms of a correlated subquery, but the outer part isn't a query, it's an update. Is this even possible in one step?
