• Seeking a free Lint for C which programmers will *want* to use

  - by Mawg

  When I try to persuade others to Lint their code I always get excuses - too difficult to set up, too difficult to understand, false positives, etc (most of which translates to too lazy, too stupid or too afraid of new things). Is there any way that I can make Linting easier? We code in C using Netbeans. Can I incorporate Splint into Netbeans? I did find a Splint GUI which was quite good, but there was no way to lint a directory tree. Any ideas? Thanks in advance

• Creating A Simple Bash Script With Multiple Commands

  - by unorthodox grammar

  Trying to create a bash script that opens gnome-terminal, and then runs ls to display the contents of a directory, but it just opens gnome-terminal. I will be creating some other scripts that also use multiple commands. My script: #!/bin/bash gnome-terminal ls -a /examplefolder EDIT: To clarify what I'm trying to achieve. I'm trying to create a script that will open gnome-terminal, list the contents of /examplefolder, and then be ready for regular terminal usage. Is this possible, or am I barking up the wrong tree?

• How do you choose to use a specific programming language?

  - by Jesús Bracamonte

  I was having a small talk between teammates about how you choose a programming language for use in a project which lead me to think that there are many criteria to choose one in the beginning of a project but no real standard. Do you chose a programming language for the syntax and semantics? Or do you choose one because it has the best support to do certain things? Or because you have better libraries? Or do you choose it for the paradigm? What criteria do you use to choose one language when you are going to do a project?

• What are good reasons to use explicit interface implementation for the sole purpose of hiding members?

  - by Nathanus

  During one of my studies into the intricacies of C#, I came across an interesting passage concerning explicit interface implementation. While this syntax is quite helpful when you need to resolve name clashes, you can use explicit interface implementation simply to hide more "advanced" members from the object level. The difference between allowing the use of object.method() or requiring the casting of ((Interface)object).method() seems like mean-spirited obfuscation to my inexperienced eyes. The text noted that this will hide the method from Intellisense at the object level, but why would you want to do that if it was not necessary to avoid name conflicts?

• Fastest bit-blit in C# ?

  - by AttackingHobo

  I know there is Unity, and XNA that both use C#, but I am don't know what else I could use. The reason I say C# is that the syntax and style is similar to AS3, which I am familiar with, and I want to choose the correct framework to start learning with. What should I use to be able to do the most possible bit-blit(direct pixel copy) objects per frame. EDIT: I should not need to add this, but I am looking for the most possible amount of objects per frame because I am making a few Bullet-Hell SHMUPS. I need thousands and thousands of bullets, particles, and hundreds of enemies on the screen at once. I am looking for a solution to do as many bit-blit operations per frame, I am not looking for a general purpose engine. EDIT2: I want bit-blitting because I do not want to exclude people who have lower end video cards but a fast processor from playing my games.

• If I were to claim I knew C++, what libraries would you expect me to know?

  - by Peter Smith

  I'm unsure as to the definition of knowing a programming language, so I'm picking C++ as an example. How much does it take to someone to be qualified as knowing C++? Should they just know the basic syntax? Template and generic-programming? Compiler flags and their purposes (Wall, the difference between O1, O2 and O3)? STL? Garbage collection strategies? Boost? Common libraries like zlib, curl, and libxml2?

• Access Control Management Tool ACM.exe

  - by kaleidoscope

  The Access Control Management Tool (Acm.exe) is a command-line tool you can use to perform management operations (CREATE, UPDATE, GET, GET ALL, and DELETE) on the AppFabric Access Control entities (scopes, issuers, token policies, and rules). Basic Syntax The command line for Acm.exe follows the basic pattern of verb-noun. For example: acm.exe <command> <resource> [-option:<option value>] This tool will automatically generate random keys, which helps ensure that they can't easily be guessed by an attacker. Note that ACM.EXE is a thin wrapper around a REST Web Service (the AC management service). That helps to remember the commands it accepts, which are the typical resource management commands for a REST service: · Get(All) · Create · Update · Delete ACM.EXE.config file can be used to configure Host, Service and the Management key for a Service Namespace.

• Why are the packages found with apt-get always horribly out of date?

  - by Andrew

  Whenever I use the package manager, it can only ever find really old versions of stuff. Example: sudo apt-get update sudo apt-get install postgresql The best it can do is version 8.4 (3 years out of date). Trying to get a later version, I get: $ sudo apt-get install postgresql-9.1 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package postgresql-9.1 I experience the same issue whenever I use the package manager, so I usually just download and build things from source. How can I make it find up-to-date software?

• What is the best way to keep track of the median?

  - by Steven Mou

  I read a question in one book: Numbers are randomly generated and stored into an (expanding) array, How would you keep track of the median? There are two data structures can solve the problem. One is the balanced binary tree, the other is two heaps which keep trace of the biggest half and the smallest half of the elements. I think these two solutions has the same running time as O(n lg n), but I am not sure of my judgement. In your opinions, What is the best way to keep track of the median?

• Free Typescript editor with definition based code completion feature

  - by NagyI

  I know that a plugin for Visual Studio exists. However i can't afford VS so i'm looking for a free alternative which can be used to code TypeScript and aware of the .d.ts definition files and can do code completion based on them. I know that Sublime Text and VIM can do syntax highlighting with the correct language definition file. However the biggest advantage of Typescript for me is that ability to give code assistance while coding. Are you aware of any editor which can do this? I'm interested even if it's in an experimental state.

  I am using 12.04. In addition to Canon MX870 printer only shows "Processing" on the status LCD, I'm not sure if I successfully removed the old MX870 driver (I removed it by using Ubuntu Software Center), then I added a new PPA, apt-get update and then: $ sudo add-apt-repository ppa:michael-gruz/canon-trunk $ sudo apt-get update $ sudo apt-get install cnijfilter-mx870series Reading package lists... Done Building dependency tree Reading state information... Done Package cnijfilter-mx870series is not available, but is referred to by another package.

• When to use identity comparison instead of equals?

  - by maaartinus

  I wonder why would anybody want to use identity comparison for fields in equals, like here (Java syntax): class C { private A a; public boolean equals(Object other) { // standard boring prelude if (other==this) return true; if (other==null) return false; if (other.getClass() != this.getClass()) return false; C c = (C) other; // the relevant part if (c.a != this.a) return false; // more tests... and then return true; } // getter, setters, hashCode, ... } Using == is a bit faster than equals and a bit shorter (due to no need for null tests), too, but in what cases (if any) you'd say it's really better to use == for fields inside equals?

• Where can I get a list of SCHEMA / PATH / KEY to use with gsettings?

  - by Sri

  After doing some research, I found that I can quickly set configuration options using the gsettings command in the terminal, instead of installing dconf-editor or gconf-editor or CCSM. But we need the SCHEMA/PATH and KEY to set the value. Syntax is: gsettings set SCHEMA[:PATH] KEY VALUE For example to never auto-hide the launcher: gsettings set com.canonical.Unity2d.Launcher hide-mode 0 And, for windows not to overlap the launcher: gsettings set com.canonical.Unity2d.Launcher use-strut true So, where can I get a list of all the SCHEMA / PATH / KEY that can be set with gsettings? No, please don't suggest the gsettings list-keys command, because I don't know the possibly hundreds of schema available.

• Which numeral systems are useful in computer science?

  - by authchir

  I am wondering which numeral system different programmers are using, or would use if their language has support for them. As an example, in C++ we can use: Octal by prefixing with 0 (e.g. 0377) Decimal by default (e.g. 255) Hexadecimal by prefixing with 0x (e.g. 0xff) When working with bitmask, I am using hexadecimal but would sometimes want to be able to express binary numbers directly. I know some programming language support it with 0b syntax (e.g. 0b11111111). Is there any other numeric system useful in some computer science domain (e.g. cryptography, codecs, 3D graphics, etc)?

• How do you navigate and refactor code written in a dynamic language?

  - by Philippe Beaudoin

  I love that writing Python, Ruby or Javascript requires so little boilerplate. I love simple functional constructs. I love the clean and simple syntax. However, there are three things I'm really bad at when developing a large software in a dynamic language: Navigating the code Identifying the interfaces of the objects I'm using Refactoring efficiently I have been trying simple editors (i.e. Vim) as well as IDE (Eclipse + PyDev) but in both cases I feel like I have to commit a lot more to memory and/or to constantly "grep" and read through the code to identify the interfaces. As for refactoring, for example changing method names, it becomes hugely dependent on the quality of my unit tests. And if I try to isolate my unit tests by "cutting them off" the rest of the application, then there is no guarantee that my stub's interface stays up to date with the object I'm stubbing. I'm sure there are workarounds for these problems. How do you work efficiently in Python, Ruby or Javascript?

• Which tips helped you learn touch-typing? [closed]

  - by julien

  I've been learning touch-typing for about two weeks now, and I'm really commited to mastering this skill. Eventhough I'm doing ok with prose already, I'm struggling with programming syntax and even more with keybindings. Those stray you away from the home row more than regular words, and aren't as easy to practice. So I often hunt and peck in order to just get it out, but when reverting to old habits like this, I find it hard to get back into the touch-typing mindframe quickly. One little trick that has helped me so far when getting lost is to reposition every finger on its home row key, and mentally visualize the layout bias of the keyboard, ie the backslash kind of alignment of key columns. It's hard to describe though and probably a bit weird... Hope you guys have better tips !

• Markup format or script for data files?

  - by Aaron

  The game I'm designing will be mainly written in a high level scripting language (leaning towards either Lua or Squirrel) with a C++ core. In addition to scripts I'm also going to need different data files. Many data files will be for static information such as graphical assets and monster types. I'd also want to create and update data files at runtime for user information like option settings and game saves. Can I get away with using plain script files (i.e. .lua or .nut files) for my data files, or is it better to use dedicated markup formats like XML or YAML? If I use script files, loaded separately from my true scripts, then I wouldn't need an extra library to read those files. Scripting languages like Lua also have table syntax that lend themselves towards data definition. On the other hand I'd have to write my own schema check code. These languages also don't seem to support serialization "out of the box" like the markup format libraries do.
