• How do I become a programmer and not some guy that can type some C?

  - by Phoxxent

  From what I understand, programming has a lot more to it than learning syntax, that it involves an understanding of what happens under-the-hood and even more. Currently, I am just a guy that can pump out a few loops in Python or C and maybe make a small-scope Zork clone as the hight of skill. So, what can I do to become an actual programmer? How can I find out what I need to know and learn it? I know this has been vaguely asked before, but I kind of want an answer of how as opposed to the whats that I have seen. Would it be nice to know how real programmers define being a programmer? yes. Is that going to actually help me (or anyone else) learn what they need to learn? no. (well, maybe.)

• 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.

• Hilfe?! Wie funktioniert mein Werkzeug?

  - by DBA Community

  Es gibt eine ganze Reihe an Oracle Tools für die Oracle Datenbank, die per Command Line Interfaces bedient werden können: Von RMAN über ADRCI, vom SQL*Loader über Export/Import, von SRVCTL über SQL*Plus. Und wie es sich für ordentliche Werkzeug gehört, besitzt auch (fast) jedes einzelne von ihnen eine eigene Hilfestellung. Wobei die Betonung eindeutig auf "eigene" liegt. Auch der ungeübte Benutzer wird sehr schnell merken, dass Oracle sich hier wohl nie so wirklich Gedanken darüber gemacht hat, die Hilfefunktionen zu vereinheitlichen - außer dass die Hilfe mehr oder weniger hilfreich ist. Die wohl interessanteste Ausprägung dieser Hilfefunktion ist hier sicherlich der RMAN, dessen umfangreiche Syntaxhilfe nur schwer zu erhalten ist - es sei denn man vertippt sich absichtlich. Solange man alles richtig macht (oder eben falsch, aber leider mit der richtigen Syntax) ist RMAN kein Hinweis über seine umfangreichen Syntaxchecker zu "entlocken". Wie man bei den vielen unterschiedlichen Oracle Tools die hilfreichen Informationen bekommt, damit beschäftigt sich unser Tipp. Weiter zum Tipp

• Are there any specific workflows or design patterns that are commonly used to create large functional programming applications?

  - by Andrew

  I have been exploring Clojure for a while now, although I haven't used it on any nontrivial projects. Basically, I have just been getting comfortable with the syntax and some of the idioms. Coming from an OOP background, with Clojure being the first functional language that I have looked very much into, I'm naturally not as comfortable with the functional way of doing things. That said, are there any specific workflows or design patterns that are common with creating large functional applications? I'd really like to start using functional programming "for real", but I'm afraid that with my current lack of expertise, it would result in an epic fail. The "Gang of Four" is such a standard for OO programmers, but is there anything similar that is more directed at the functional paradigm? Most of the resources that I have found have great programming nuggets, but they don't step back to give a broader, more architectural look.

• Algorithm for perfect non-binary graph layout

  - by mariki

  I have a complex non-binary graph model. Each tree node can have multiple children&parents (a node can also have a connection to it's "brother"). A node is represented as square on screen with lines to the connected nodes. For that I want to use Draw2D and GEF libraries. The problem I am facing is the graph layout. I need a nice algorithm that can reposition the square nodes and the connections with minimum intersections and also make it symmetric as possible.

• 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.

• What is the best way to become a professional in PHP and Website Building?

  - by Mr.TAMER

  I would like to become a professional in php, I have learned nearly all about the language syntax and concepts and I have a good knowledge in C and C++, which made it easier to become familiar with PHP. (Of course, I learned MySql too.) But I don't feel like being able to build even a little good website of my own! It looks like PHP is all about knowing lots of functions and using them, while in fact I don't think it's like that, is it? How can I become a professional in PHP and Website Building? I would do anything and spend whatever amount of time required for that. EDIT I've also a very good knowledge in HTML and a normal knowledge in CSS and JavaScript. Sorry for not mentioning that, I just thought it was implicitly included.

• 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?

• 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?

• Any board-like platform but only for files instead of text posts? [on hold]

  - by Janwillhaus

  I am looking for a (best open-source or free but also commercially available) CMS platform that is built similarly to bulletin boards (for example phpBB) but instead of text posts, registered users can upload files that can be rated, commented etc.) I am aware of the number of board CMSes that have file-database plugins, but that is not what I want. I want to have a system that focuses on the files rather than on the postings. Or do you have any alternative ideas on solutions to the problem? I need the following functions CMS focused on file management Files that can be categorized (in a tree-like view for example) Comments and ratings can be added to files Users that can be provided various rights around the platform (moderation, commenting, exclusion of non-registered users, etc.) Users can upload files themselves (for further moderation

• Install Opera on 64-bit

  - by maaartinus

  I tried to follow the instructions on the opera page, but it didn't work. I was assuming the base install should be the same for 64-bit, but it doesn't look so. After executing wget -qO - http://deb.opera.com/archive.key | sudo apt-key add - successfully sudo apt-get install opera says Reading package lists... Done Building dependency tree Reading state information... Done Package opera is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'opera' has no installation candidate Below on the page I see A 64 bit Linux version is available, you should get it automatically either from the repositories or from Opera I haven't tried to download it manually, since I prefer to get it from a repo. It it possible?

• Should you document everything or just most?

  - by TheLQ

  It seems a bit of a controversial subject to document everything, including the "JavaBean" syntax of getters and setters for fields: People say its needlessly long and repetitive breaking DRY (don't repeat yourself), that the naming convention should explain everything, and it clutters code/documentation. Sometimes those arguments work. But other times, you end up with this: Above is common to open source projects that do boldly follow those principles. Your left with entirely useless documentation. That doesn't explain anything about whats going on underneath, the possible effects, or even what the expected value is (could it be null or never null? I don't know, the Javadoc doesn't tell me). So when should I document? Do I document everything even if it occasionally clutters code? Or do I document nothing since in my eyes its "obvious"?

• How to copy files while keeping directory structure?

  - by Cubic

  This is for a java project, but the same concept can be applied more generally: Basically, I have a projects with all *.java files located in some sub directory of src. Now I want to grab all directories with the name test in that directory tree and move them into a new directory called tests, e.g.: src->com->a1 -> A.java -> B.java -> test -> test1.java -> test2.java to src->com->a1 -> A.java -> B.java tests->com->a1->test -> test1.java -> test2.java How would I best do that?

• Which hidden files and directories do I need?

  - by Sammy Black

  In a previous question, I explained my situation/plan: backing up home directory on external drive, reformatting laptop drive, installing 14.04, putting home directory back. (It hasn't happened yet because I can't seem to find the down time, in case things aren't working right away.) It occurred to me that maybe I don't want all of those hidden files and directories (e.g. .local/share/ubuntuone/syncdaemon/, .cache/google-chrome/, etc.) Just judging by the amount of time in copying, I can tell that some of these hidden directories are large. Question: Are there any hidden directories that I obviously don't need/want when I have the laptop running an updated distribution? Will they cause conflicts? (I plan on copying the backed-up directory tree back onto the laptop with the --no-clobber option.)

• New insights I can learn from the Groovy language

  - by Andrea

  I realize that, for a programmer coming from the Java world, Groovy contains a lot of new ideas and cool tricks. My situation is different, as I am learning Groovy coming from a dynamic background, mainly Python and Javascript. When learning a new language, I find that it helps me if I know beforehand which features are more or less old acquaintances under a new syntax and which ones are really new, so that I can concentrate on the latter. So I would like to know which traits distinguish Groovy among the dynamic languages. What are the ideas and insights that a programmer well-versed in dynamic languages should pay attention to when learning Groovy?

• Diagramming software with API allowing high customisation of shapes and actions

  - by jenson-button-event

  I am after something like Visio or Lucid. A relatively simple charting/diagramming tool, to build tree-like structures from (my) pre-defined nodes (squares), but with a powerful API. Requirements: limit the type of objects allowed to be dropped on the diagram validate a model (e.g. node of type A must precede node of type B; must enter node Title) export a model import a model Our domain is very specific, and its a tool we'd want to offer to some of our power users. The $500 Visio licence isn't really within the business model. I'll put no constraints on framework or deployment (web or desktop) - is there anything out there?

• Is there much difference between X86 Assembly language on Windows and Linux?

  - by Logan545

  I'm a complete beginner at Assembly, and my aim is to learn as much as I can to do with Assembly to one day I can reach expert level (I know I'm way off right now, but you never know). My only problem is this: I've got two books which both teach assembly, one on a Linux and the other on Windows. They are Jeff Duntemann's Assembly Language Step By Step (the linux one) and Introduction to 80x86 Assembly Language and Computer Architecture (the windows version). If I want to get the best out of assembly, should I do this on linux and windows? Also, is the syntax the same on Windows and Linux or will I have teach my self again when learning on the other OS( which is my main concern, I want to be able to use assembly on windows and linux).
