• Is it worth it to learn an esoteric programming language?

  - by Thomas Owens

  Wikipedia: An esoteric programming language (sometimes shortened to esolang) is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke. There is usually no intention of the language being adopted for real-world programming. Such languages are often popular among hackers and hobbyists. This use of esoteric is meant to distinguish these languages from more popular programming languages. Some more popular languages may appear esoteric (in the usual sense of the word) to some, and though these could arguably be called "esoteric programming languages" too, this is not what is meant. I think it might be worth it, just to learn a new language and go through the process, although only if you don't have anything else to do (like a real project or learning a new real language). But what does the community think? Is there some value in these languages?

• firefox displaying .swf with wrong dimensions

  - by John Leonard

  I can't figure this one out. I have a flex app with fixed dimensions (950 x 700). I'm compiling the swf and using the default wrapper that flex generates. in some instances of Firefox, the dimensions are wrong. On top of that, with different domains, I get the .swf rendered with different dimensions (both wrong). Firefox 3.6.3 on one computer works fine. On another, the dimensions are off. Swf example and if you don't see a clipped swf...here are the screenshots. Rendered incorrectly on one domain And rendered in another domain with different bad dimensions. I'm at a total loss. When I embed the .swf with swfobject, I get the same issue. In the example you see, there's nothing in the app except for a single label centered on the stage.

• rubygem "Argument list too long"

  - by mehmermaid

  My problem is that during or after running a process which uses Ruby intensively, when I use any gem command including gem --version or gem install rake, it hangs for just over a minute and then gives me this error: $ gem list /Users/username/.rvm/bin/gem: line 5: /Users/username/.rvm/bin/gem: Argument list too long /Users/username/.rvm/bin/gem: line 5: /Users/username/.rvm/bin/gem: Unknown error: 0 file at : line 5: /Users/username/.rvm/bin/gem #!/usr/bin/env bash if [[ -s "/Users/username/.rvm/environments/ruby-1.8.7-p334" ]] ; then source "/Users/username/.rvm/environments/ruby-1.8.7-p334" exec gem "$@" # this is line 5 else echo "ERROR: Missing RVM environment file: '/Users/username/.rvm/environments/ruby- 1.8.7-p334'" >&2 exit 1 fi The only way that I have found to get this working again is to restart my computer, which is obviously undesirable. I am using OSX 10.6.5 I have spent quite a while trying to find anyone else who has had this problem, and been unsuccessful. Do you have any idea why this might be happening?

• unable to get into windows 7 or ubuntu after system file back on a dual boot system

  - by John Jiang

  I installed ubuntu on my dell xps 9000 which originally has a window 7 installed. So after I did system file back up as told by windows 7 and restarted my computer, I received the following message right after restarting in the black screen: roughly like this: ubuntu grub error, " " symbol cannot be found. I was wondering how I can get access into windows 7 and uninstall ubuntu all together. I actually had the same booting problem after system backup before and the solution was to install two extra ubuntus but I'd prefer not to do that. I'd highly appreciate any help!

• Where to Start with build a personal site and WordPress, CSS and CMS

  - by Simon

  Hey guys im in a very confused state of mind at the moment and need some help with Word Press and generally starting a website. My parents have had a business for 20 years and have finally decided to get a website! As im studying IT and Business i said id get it done for them. Rather than design it from scratch i used a template which i bought from themeforest.net (awesome template!) and yesterday a friend mentioned in passing using word press as a CMS which i had never heard of before, and he left before i could ask any questions. SO basically i have a site working on my computer and i have no idea how to get it live as a .com or .com.au, so far as i can see wordpress is a blog with .wordpress.com which isnt what im looking for. Thanks in advance Simon

• What is the best euphemism for a non-developer?

  - by Edward Tanguay

  I'm writing a description for a piece of software that targets the user who is "not technically minded", i.e. a person who uses "browser/office/email" and has a low tolerance for anything technical, he just "wants it to work" without being involved in any of the technical details. What is the best non-disparaging term you have seen to describe this kind of user? non-technical user low-tech user office user normal user technically challenged user non-developer computer joe Surely there is some official, politically-correct retronym for this kind of user that the press and software marketing use.

• How can I handle template dependencies in Template Toolkit?

  - by Smack my batch up

  My static web pages are built from a huge bunch of templates which are inter-included using Template Toolkit's "import" and "include", so page.html looks like this: [% INCLUDE top %] [% IMPORT middle %] Then top might have even more files included. I have very many of these files, and they have to be run through to create the web pages in various languages (English, French, etc., not computer languages). This is a very complicated process and when one file is updated I would like to be able to automatically remake only the necessary files, using a makefile or something similar. Are there any tools like makedepend for C files which can parse template toolkit templates and create a dependency list for use in a makefile? Or are there better ways to automate this process?

• Working with images in WCF

  - by hgulyan

  Hi, I have a desktop application that needs to upload/download images to/from service computer over TCP Protocol. At first, I stored images in file system, but I need to in MS SQL DB to compare which solution is better. Number of images is over half a million. I don't know yet will there be any limitation on size of a photo. If you have done smth like that, please, write what your opinion upon this question. Which one is faster, more safe? Which of them works better with this number of photos? If I'll store on DB, do I need to store images apart from all other tables which I use for my application and which type works better - image or varbinary on DB?..and so on. Thank you.

• Script to download file and rename according to date on Windows Vista machine?

  - by Dave

  Hi, I need to daily run a script that will download a file from a fixed location and save it on my computer with an appropriate filename-YYYYMMDD-HHSS.ext timestamp. I need a historical record of what that file was at that particular time. I can manually check and see what the changes were, so compairson not needed. (I was looking for an online service that would do this for me, but I think a locally running script on my machine would be good enough). Although i do have php on my machine, i would prefer if its a pure windows builtin solution, just in case i have to (likely) adapt it to someone else's system (non-techies). If someone has something like this and can contribute the code - help would be most appreciated!! D

• Can Java ServerSocket and Sockets using ObjectIOStreams lose packets?

  - by Joel Garboden

  I'm using a ServerSocket on my server and Sockets that use ObjectIOStreams to send serializable objects over the network connection. I'm developing an essentially more financial version of monopoly and thus packets being sent and confirmed as sent/received is required. Do I need to implement my own packet loss watcher or is that already taken care of with (Server)Sockets? I'm primarily asking about losing packets during network blips or whatnot, not full connection error. E.g. siblings move a lead plate between my router and computer's wi-fi adapter. http://code.google.com/p/inequity/source/browse/#svn/trunk/src/network Code can be found under network-ClientController and network-Server

• Redundancy algorithm for reading noisy bitstream

  - by Tedd Hansen

  I'm reading a lossy bit stream and I need a way to recover as much usable data as possible. There can be 1's in place of 0's and 0's in palce of 1's, but accuracy is probably over 80%. A bonus would be if the algorithm could compensate for missing/too many bits as well. The source I'm reading from is analogue with noise (microphone via FFT), and the read timing could vary depending on computer speed. I remember reading about algorithms used in CD-ROM's doing this in 3? layers, so I'm guessing using several layers is a good option. I don't remember the details though, so if anyone can share some ideas that would be great! :) Edit: Added sample data Best case data: in: 0000010101000010110100101101100111000000100100101101100111000000100100001100000010000101110101001101100111000101110000001001111011001100110000001001100111011110110101011100111011000100110000001000010111 out: 0010101000010110100101101100111000000100100101101100111000000100100001100000010000101110101001101100111000101110000001001111011001100110000001001100111011110110101011100111011000100110000001000010111011 Bade case (timing is off, samples are missing): out: 00101010000101101001011011001110000001001001011011001110000001001000011000000100001011101010011011001 in: 00111101001011111110010010111111011110000010010000111000011101001101111110000110111011110111111111101 Edit2: I am able to controll the data being sent.

• How to see a branch created in master

• What are the things I use every day programmed with?

  - by sub

  It isn't so interesting to find out what this text editor here or that IRC client there was programmed with, also it isn't really hard and neither are there really suprising things to come out. Wow so it was programmed in Python, I didn't expect that. What I'm asking is: What are the things that we daily see, use or generally need programmed with? To name a few (really only a few of those out there): My alarm clock It has many features so it would probably be hard programming it with assembler or whatever, so did they probably use a programming language? If yes, which? My electrical tooth brush The (stupid) board computer of my car. (6 years old, has few features but a red LED display showing me how cold/warm it is outside and how much gas I'm using up per hour at the moment) Those (old) plastic mini-mini computers with the LCD(?) displays that only had one game available on them: PacMan, tetris or so. I'm not directly thinking of this but it may be similar: Other, probably more interesting, things I didn't mention

• Include Problem with Objective-C++ and OpenGL

  - by Stephen Furlani

  Hello, I feel silly asking this but I've searched for 'include problems' and have only come up with basic stuff. I'm working with an API that includes/imports in their header files (ARGH! HATE ANGER DESTRUCTION). One of these Obj-C files #import "OpenGL/CGLMacros.h" which #define's things like glMatrixMode(...); In my code I need the glMatrixMode(...); from #include "OpenGL/gl.h" but it won't access it! I can't edit the headers from the (poorly) coded API to put the includes in their definition files. What can I do? If the CGLMacros.h file starts out like /* Copyright: (c) 1999 by Apple Computer, Inc., all rights reserved. */ #ifndef _CGLMACRO_H #define _CGLMACRO_H Can I put a #define _CGLMACRO_H before I include the offending API header file? -Stephen

• MSMQ.MSMQQueueInfo PathName Not Accepted

  - by user357596

  I am using MSMQ.MSMQQueueInfo with jscript on Windows 7 (the latest MSMQ version). This is being run on a domain joined computer. For some reason unknown to me, it just will not accept the PathName I give it (which is in an acceptable format). Here is the code: var qi = new ActiveXObject ("MSMQ.MSMQQueueInfo"); qi.PathName = "FormatName:Direct=OS:mycomputer\\Private$\\myqueue"; I know this PathName works, because I use the exact same path in c#, and that works: queue = new MessageQueue("FormatName:DIRECT=OS:" + contollerName + "\\Private$\\" + queueName); When the code "qi.Open()" in the jscript code attempts to execute, it returns this error message: The queue path name specified is invalid. Has anyone else run into this? Ideas? Comments? Suggestions? Thank you in advance!

• Good HTML/CSS/PHP editor that is free and multi-platform?

  - by Earlz

  Hello, I have recently given up on using Visual Studio for Windows editing. See, PHP isn't really important as I have hardly any pages that use it, but in VS, if it smells PHP then it won't treat it as HTML and thus will all be plainly formatted.. so.. I'm looking for some sorta HTML/CSS/PHP editor that is free and multi-platform(so I can also use it at my home OpenBSD computer) And please don't suggest emacs or vi. I'm learning more and more of nvi, but I'm looking for a graphical editor right now. Can anyone suggest a good editor for my needs?

• How do I get accurev to find a moved workspace?

  - by eric f

  I created a workspace in AccuRev under M:\EclipseWorkspaces\. The project checked out fine. Then I moved the project to C:\EclipseWorkspaces\. Now AccuRev thinks the project does not exists. This is probably because AccuRev is looking for the project on my M drive. How do I get AccuRev to find my project? I am using version 5.3. This computer is slow so I'd like to do this using the CLI. Update: I deleted the workspace in the AccuRev client.... Can I add the workspace on my C drive into my stream in AccuRev?

• allowDefinition='MachineToApplication' error when publishing from VS2010 (but only after a previous

  - by burnt_hand

  I can run my Asp.Net MVC 2 application without an issue on my local computer. Just Run / Debug. But if I have already built it, I can't publish it! I have to clean the solution and publish it again. I know this is not system critical, but it's really annoying. "One Click Publish" is not "Clean solution and then One click publish" The exact error is as follows: Error 11 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. I suspect it's something to do with the Web.Config in the Views folder, but then why only after I build once previously. And just to note, the app works fine once published.

• Disable Ctrl-Alt-Del and shutdown for kiosk

  - by acidzombie24

  I finished an app for a client. After talking for a bit he would like me to do an additional app or recommend one for their kiosk. The client would like a way to prevent the computer from shutting down. They like to disable Ctrl+Alt+Delete (also so processes cant be killed), Alt+F4 to close their browser and no windows button to make the start menu pop up for the user to click or use keyboard to shutdown. Obviously there should be a way to unlock it I told them i'll look into it but they really don't need it. They are using Windows 7. Is there a WinAPI call I can use or an already existing app or a lib to do this?

• java/swing: Shape questions: serializing and combining

  - by Jason S

  I have two questions about java.awt.Shape. Suppose I have two Shapes, shape1 and shape2. How can I serialize them in some way so I can save the information to a file and later recreate it on another computer? (Shape is not Serializable but it does have the getPathIterator() method which seems like you could get the information out but it would be kind of a drag + I'm not sure how to reconstruct a Shape object afterwards.) How can I combine them into a new Shape so that they form a joint boundary? (e.g. if shape1 is a large square and shape2 is a small circle inside the square, I want the combined shape to be a large square with a small circular hole)

• Testing perceived performance

  - by Josh Kelley

  I recently got a shiny new development workstation. The only disadvantage of this is that the desktop apps I'm developing now run very, very fast, and so I fear that parts of the code that would be annoyingly slow on end users' machines will go unnoticed during my testing. Is there a good way to slow down an application for testing? I've tried searching around, but all of the results I've been able to find seem pretty fiddly to set up (e.g., manually setting up a high-priority CPU-bound task on the same CPU core as the target app, or running a background process that rapidly interrupts and resumes the target app), and I don't know if the end result is actually a good representation of running on a slower computer (with its slower CPU, slower RAM, slower disk I/O...). I don't think that this is a job for a profiler; I'm interested in the user's perception of end-to-end performance rather than in where the time goes for particular operations.

• What's the diffrence btw System property and system environment variable

  - by khue

  Hi all I am not clear about this. When I run a java App or run an Applet in applet viewer,( in the IDE environment), System.getProperty("java.class.path") give me the same as System.getenv("CLASSPATH"), which is the CLASSPATH env variable defined. But when I deploy my applet to webserver and access it from the same computer as a client, I get different result for the two (System.getProperty("java.class.path") only point to jre home and System.getenv("CLASSPATH") return null). And here is some other things that make me wonder: For the applet part, the env var JAVA_HOME, i get the same result when deploying the applet in a browser as well as Applet Viewer. And if I define myself a env variable at system level, and use getenv("envName") the result is null. Is there anyway I can define one and get it in my java program? Thanks a lot Regards K.

• Windows XP Home Edition SP3 cant recognise PCMIA SD Card

  - by Pozo

  System Specifications: Laptop : Dell Inspiron 6000 OS: Windows Home Edition SP3 SD Adapter: Hagiwara Smart Media Adapter I inserted the card into the slot, windows xp recognises the device, lists the pcmia controller on the device manager list, an entry appears under the IDE ATA/ATAPI category on the device manager as well. However, the device does not show under my computer and the driver does not get assigned a letter number. I checked the system logs from the device manager and there were no logged errors. Checking the Hagiwara support website, the manufacturer indicates that the adapter driver is the same as the windows xp pcmia controller. Checking Dell's website, no specific drivers were listed for that either. General Search on the web indicates that multiple people face similar problems with their SD cards, yet none actually spell out the route issue that causes this. Please let me know if you have any suggestions for further debugging. Thanks in advance

• Registry corrupted for testing?

  - by Emile

  Hi. Forgive my ignorance. I'm a lowly LAMP stack developer and this is my first post for "c++". We had an Internet Explorer add-on commissioned but then lost support. Allegedly each version has to be have been tested "on a fresh computer since old add-ons could have cause registry errors." I'm not familiar with IE add-on development (or c++ dev). Is this common? Can't one simply reverse registry errors? How to continue testing iterations on one machine? Thanks!

• Efficient way to create/unpack large bitfields in C?

  - by drhorrible

  I have one microcontroller sampling from a lot of ADC's, and sending the measurements over a radio at a very low bitrate, and bandwidth is becoming an issue. Right now, each ADC only give us 10 bits of data, and its being stored in a 16-bit integer. Is there an easy way to pack them in a deterministic way so that the first measurement is at bit 0, second at bit 10, third at bit 20, etc? To make matters worse, the microcontroller is little endian, and I have no control over the endianness of the computer on the other side.
