• How do I generate (and label) a random integer with python 3.2?

  - by An hero

  Okay, so I'm admittedly a newbie to programming, but I can't determine how to get python v3.2 to generate a random positive integer between parameters I've given it. Just so you can understand the context, I'm trying to create a guessing-game where the user inputs parameters (say 1 to 50), and the computer generates a random number between the given numbers. The user would then have to guess the value that the computer has chosen. I've searched long and hard, but all of the solutions I can find only tell one how to get earlier versions of python to generate a random integer. As near as I can tell, v.3.2 changed how to generate and label a random integer. Anyone know how to do this? Thanks!

• From Java to Javascript? [duplicate]

  - by theGreenCabbage

  This question already has an answer here: Are there any OO-principles that are practically applicable for Javascript? 2 answers I am primarily a Java programmer. Because of its OO principles and the general paradigm of Java programming, like wrapping things in static variables, and having things return specific types, heavily aids me in "visualizing" a program. Instead of thinking of a big program, I can, instead, focus on smaller organized parts of my eventual program, and add functionality and build up from there. Thus, I have trouble programming in other languages. Or at least, I have not been able to program in the same ability as I do in Java compared to other languages. I know Javascript has OO principles, so I'd like to learn this language in a OO-based like I would program with Java. Is this possible?

• Relation between " lines of the longest working program " in a language and familiarity with it?

  - by Tim

  In some computer master program online application, it says: Please list the programming languages in which you have written programs. For each language, indicate the length in lines of the longest working program you have written in that language. You may approximate, but only count those parts of the program that you wrote yourself. I don't quite remember that, and I have never counted the lines of each program. Do programmers always know approximately how many lines in each of his programs, and keep record of them? What is the relation between " lines of the longest working program " in a language and familiarity with it? Typically, how many lines will indicate the programmer being excellent, good, fair, or unfamiliar with the language? Is knowing "lines of the longest working program" really helpful?

• Verizon Fivespot firewall exceptions

  - by Patrick

  I have a Verizon Fivespot Wi-Fi router and am having issues connecting to the computer that uses it to get on the internet. I am able to connect to the Fivespot admin pages remotely and I am able to connect to the internet from the computer behind the Fivespot. I've tried asking this on superuser but have gotten nothing, I figure this is pertinent to programmers working on remote computers as well. There are two sections pertinent to this issue, Port Filtering And, Port Forwarding I've tried each individually and both together but cannot access anything through the router except for the admin page. I am trying to connect through SSH on Port 22 to an Ubuntu 10.04 box over wifi. I have called Verizon Tech Support but they were unhelpful, the person essentially read what it says on each screen without any elaboration. Any help is greatly appreciated!

• What is the difference between remote procedure call and web service

  - by xiao

  Is there any clear definition about RPC and Web Service? A quick wikipedia search shows: RPC: Remote procedure call (RPC) is an Inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. Web Service: Web services are typically application programming interfaces (API) or web APIs that are accessed via Hypertext Transfer Protocol and executed on a remote system hosting the requested services. Web services tend to fall into one of two camps: Big Web Services[1] and RESTful Web Services. I am not quite clear what the real difference between the two things. It seems that one thing could belongs to RPC and is kind of web service at the same time. Is Web Service a higher level representation of RPC?

• How to use files/streams as source/sink in PulseAudio

  - by Nilesh

  I'm a PulseAudio noob, and I'm not sure if I'm even using the correct terminology. I've seen that PulseAudio can perform echo cancellation, but it needs a source and a sink to filter from, and a new source and sink. I can provide my mic and my audio-out as the source and sink, right? Now, here's my situation: I have two video streams, say, rtmp streams, or consider two flv files, say at any given moment, stream X is the input stream that's coming from another computer's webcam+mic and stream Y is the output stream that I'm sending, (and it's coming from my computer's webcam+mic). Question: Back to the first paragraph - here's the thing, I don't want to use my mic and my audio-out, instead, I want to use these two "input" and "output" streams as my source and sink so to speak (of course, I'll use xuggler maybe, to extract just the audio from X and Y). It may be a strange question, and I have my reasons for doing this strange this - I need to experiment and verify the results to see.

• How to determine the port numbers for peripheral devices?

  - by smwikipedia

  I know that peripheral devices such as a hard driver, a floppy driver, etc are controlled by reading/writing certain control registers on their device controllers. I am wondering about the following questions: Is it true that when these peripheral devices are plugged onto the computer, the addresses(port numbers) of their control registers are thus determined by how they are attached to the address bus (i.e. the hard-wiring rules, not any soft things)? Who makes the scheme of the port number assignment? If I was given a naked computer(with no operating system and with many peripheral devices), how could I figure out the port number assignment so I can use them to control peripheral deveices. At last and as usual, thanks for your patience and reply. 8^)

• Programming cookbook? [closed]

  - by user73669

  Possible Duplicate: What is the single most influential book every programmer should read? Hello With sites like The Daily WTF and recurring threads on Slashdot and elsewhere about bad programming, I figured that, to avoid people reinventing the wheel (badly or not), there should be a good, fat book on programming that would go through typical programming problems and show good, known algorithms, either in pseudo-code or some language with an easy syntax so that the language is not an issue. Here's the list of books on the subject I saw at my local computer bookstore. Can you recommend a couple, or add to this list if it's missing better options? The art of computer programming Code complete Masterminds of programming 97 things every programmer should know The passionate programmer Pragmatic thinking & learning Coders at work The algorithm design manual Algorithms and programming How to think about algorithms How to think like a programmer Why programs fail Beautiful data Beautiful code The productive programmer Solid code Write great code Clean code Programming language pragmatics Hello world Learning Processing Learn to program Thank you.

• Writing a basic C Shell - understanding argv[] [on hold]

  - by Flame

  I have an assignment for my class to write a basic C Shell. I have found many pages that explain parts of it and some fully implemented code. I'm not going to copy, i'm just using it right now as a way to get started. So I'm at the beginning of this project obviously. One example I am looking at parses the user's input and stores a pointer to the beginning of the argument in char *argv[3]; Am I just misunderstanding this or would this technically break if there are more than 3 arguments? (say /a.out arg1 arg2 arg3 etc). Would I wanna malloc this somehow? I know a.out is considered argv[0], and the arguments argv1 - however many there are. It's probably bad practice to have too many arguments for a program, but I still would at least want to address it as I don't know what my TA's are going to use to test my shell.

• It is worth planning before jumping in the code?

  - by Rushino

  I always thought that planning is important for a game. But i don't know at which point. Some are telling me to code instead of planning but i feel like its still important because when you will be in the code you will know what to do next more easily. I am currently working on a game that will have lots of content so i decided to start a design document introducing thoses content and at a side-level i am doing proofs of concept to check if it can be done. Parts of each proofs of concept then could be used later in the real game. EDIT: I am working alone on this project. So my question is : It is worth planning before jumping in the code ? Im still interested to know what others have to say about this. Cause i still get some poeple saying i should code instead of thinking.. so what your opinion on this ?

• Theme sometimes fails to load on some UI elements

  - by Neil

  I have no idea if this error as been seen before or not, I have looked around and found people saying they have errors that sound the same but none of the fixes work, my issue is that sometimes the theme does not load some parts of the UI, (the buttons and icons in this case) but the rest is just fine (window bars e.t.c) so I have no idea what the issue is, it works just fine for the most part but sometimes has this bug, if you restart the system it tends to fix it for some time so its hard to see how it could be a graphic card error, however I am very new to linux systems so I may be missing someting very fundamental here. Thank-you in advance. This image shows my problem

• Dropbox install stuck at 99%, how do I fix it? (and any dpkg errors)

  - by John

  I tried to install Dropbox using How to install Dropbox?, or with apt-get install nautilus-dropbox. Dropbox loads until 99% and then hangs, causing the system to go to 100% cpu usage. If I reboot or close the terminal, I sometimes get dpkg errors which prevent me from using apt-get or Software Center to perform any package management functions. I would like to resolve all these and just get Dropbox working. How do I do that? Note: This question is possibly answered in two parts: The accepted answer tells you how to install Dropbox. But if you have dpkg errors, see this answer before you use answer 1 to install Dropbox.

• Using NPM to share resources between UI projects [on hold]

  - by guy mograbi

  I am a UI team leader. My team has a lot of projects using different languages/technologies. In some parts we will rewrite (gradually - @Ampt this is for you) the application in order to enable new fresh technologies in and get old dinosaurs out. I am going to use Node Package Manager to set up an "all powerful" build/dependency manager. Can I use NPM to depend on a private github repository? Can I use NPM to depend on SVN? Will NPM play nice with quickbuild? Since each project might have a slightly different structure (think jetty/maven or play!framework) can I configure NPM to install some dependencies in different folders while still running it from the project's root? How can I, using NPM, get development resources out and build a packaged product? (like a war) Yes/No - is there a reason to use grunt? No discussion, just one liners.

• Finding out which tile a mouse click landed in

  - by Shard

  I am working on an icometric grid based game and im having an issue trying to link a mouse click from the user to a tile. I have been able to split the problem into 2 parts which is first finding a rectangle that sourounds a tile, which I have been able to do but the second part of figuring out from the rectangle which tile the click landed in has got me stumped. Here is an example of a rectangle with tiles on the inside: The rectangle is 70px long and 30px high so if i use an input of say 30x(top)/20y(left) how would I go about determining which tile this fell into?

• Will GMails Greasemoney API help me: composing and sending messages, adding a button to the compose view, listing and sending drafts [migrated]

  - by Kent

  I want to create a Greasemonkey script for GMail and I've browsed through the GMail Greasemonkey 1.0 API documentation. I haven't fully understood what the API actually provides, which leads me to ask a few concrete questions. How will the API help if I want to: Add a button to the Compose view which executes some of my code. Compose and send a new message from scratch. List the current drafts. Pick a draft and send it. From what I can see it'll help me with 1 above, but I don't see any real interaction API parts which can help me with 2-4.

• why don't more programming languages have builtin interfaces to the window manager?

  - by Naveen

  Programming is at the heart about automating tasks on a computer. Presumably those tasks would normally be done manually by a human. Humans use the computer through the keyboard, mouse, and interaction with the console or the window manager. But very few languages have built in functions that provide an interface to these basic computing objects. A notable exception is autohotkey, an open source language on windows, providing builtin functions that allow the following simple tasks: * Get Pixel Information * Get mouse position * Keyboard macros * Simulate key strokes * Simulate mouse click * Window management See examples on rosettacode. There have been various attempts on linux, many of which were stopped without explanation. One is the inactive tcl library: android. Search google code for android, lang:tcl

• C redevient le langage le plus utilisé devant Java et C++, d'après le classement des langages de pro

  Le C redevient le langage de programmation le plus utilisé Devant Java et le C++, d'après TIOBE Software TIOBE Software publie chaque mois son classement (le TIOBE Programming Community index) des langages de programmation. D'après cet index, pour la première fois depuis 4 ans, Java perd sa place de langage le plus populaire au profit du C qui retrouve donc le top du classement. Le C "est assez constant au fil des années, il varie entre 15% et 20% de parts de marché depuis presque 10 ans. Donc, la raison principale de cette place de numéro 1 n'est pas une progression du C, mais plutôt la baisse de son concurrent Java", explique l'analyse qui accompagne ce ...

• Is this a pattern? Proxy/delegation of interface to existing concrete implementation

  - by Ian Newson

  I occasionally write code like this when I want to replace small parts of an existing implementation: public interface IFoo { void Bar(); } public class Foo : IFoo { public void Bar() { } } public class ProxyFoo : IFoo { private IFoo _Implementation; public ProxyFoo(IFoo implementation) { this._Implementation = implementation; } #region IFoo Members public void Bar() { this._Implementation.Bar(); } #endregion } This is a much smaller example than the real life cases in which I've used this pattern, but if implementing an existing interface or abstract class would require lots of code, most of which is already written, but I need to change a small part of the behaviour, then I will use this pattern. Is this a pattern or an anti pattern? If so, does it have a name and are there any well known pros and cons to this approach? Is there a better way to achieve the same result? Rewriting the interfaces and/or the concrete implementation is not normally an option as it will be provided by a third party library.

• XML-RPC in CodeIgniter is for creating a API?

  - by ajsie

  I have read some tutorials about creating an API and i wonder if XML-RPC and XML-RPC server in CodeIgniter are for creating this? If yes, what are the benefits of using these classes rather than im just using regular class/methods/params to create my API interface. This is what it said in the documentation: Quite simply it is a way for two computers to communicate over the internet using XML. One computer, which we will call the client, sends an XML-RPC request to another computer, which we will call the server. Once the server receives and processes the request it will send back a response to the client.

• Send and receive data trough the power network

  - by luvieere

  I'm not interested in a hardware solution, I want to know about software that may "read" modulated signal received trough the power supply - some sort of a low-level driver that would access the power signal in a convenient place and demodulate it. Is there a way to receive signal from the computer's power supply? I'm interested in an API or library that would allow the computer to be seen as a node in a Power Line Communication network and receive data directly through the power cable, without the need for a converter. Is there any active research in this field? Edit: There is software that reads monitors and displays internal component voltages - DC voltage after being converted and filtered by the power supply - now I need is a method of data encoding that would be invariant to conversion and filtering, the original signal embedded in AC being present in some form within the converted DC signal.
