• Is fish or zsh better for shell programming?

  - by Julien Nicoulaud

  I'm a bash user willing to switch to a more friendly and advanced shell. I read a lot of good things about zsh, but I gave a quick test at fish and it seems great too. Both seem very close in term of features, what is your opinion about those two shells especially as regards shell programming?

• Generic HTTP 500 Error Message On Hosted Sites (like GoDaddy)

  - by Jimbo

  I decided to post this because I battled to find out how to do it and couldnt see anything on Stackoverflow about it. Often when you host with a provider like GoDaddy, they have "Custom Error Messages" set to ON. What I didnt realise was that the web.config settings dont just apply to ASP.NET, they apply to all applications on YOUR IIS site and hence will sort this problem out for Classic ASP as well (very few GoDaddy support people even know this) All you need to do is add the following to your web.config OR, for those using Classic ASP, just create a web.config file in your ROOT with this code in it. <configuration> <system.webServer> <asp scriptErrorSentToBrowser="true"/> <httpErrors errorMode="Detailed"/> </system.webServer> </configuration>

• How to troubleshoot performance issues of PHP, MySQL and generic I/O

  - by jbx

  I have a WordPress based website running on a shared hosting. Its response time is very decent (around 2s to retrieve the HTML page and 5s to load all the resources). I was planning to move it to a dedicated virtual server (Ubuntu 12.04 LTS), which should theoretically improve things and make them more consistent given its not shared. However I observed severe performance degredation, with the page taking 10seconds to be generated. I ruled out network issues by editing /etc/hosts on the server and mapping the domain to 127.0.0.1. I used the Apache load tester ab to get the HTML, so JS, CSS and images are all excluded. It still took 10 seconds. I have Zpanel installed on the server which also uses MySQL, and its pages come up quite fast (1.5s) and also phpMyAdmin. Performing some queries on the wordpress database directly through phpMyAdmin returns them quite fast too, with query times in the 10 to 30 millisecond region. Memory is also sufficient, with only 800Mb being used of the 1Gb physical memory available, so it doesn't seem to be a swap issue either. I have also installed APC to try to improve the PHP performance, but it didn't have any effect. What else should I look for? What could be causing this degradation in performance? Could it be some kind of I/O issue since I am running on a cloud based virtual server? I wish to be able to raise the issue with my provider but without showing actual data from some diagnosis I am afraid he will just blame my application. UPDATE with sar output (every second) when I did an HTTP request: 02:31:29 CPU %user %nice %system %iowait %steal %idle 02:31:30 all 0.00 0.00 0.00 0.00 0.00 100.00 02:31:31 all 2.22 0.00 2.22 0.00 0.00 95.56 02:31:32 all 41.67 0.00 6.25 0.00 2.08 50.00 02:31:33 all 86.36 0.00 13.64 0.00 0.00 0.00 02:31:34 all 75.00 0.00 25.00 0.00 0.00 0.00 02:31:35 all 93.18 0.00 6.82 0.00 0.00 0.00 02:31:36 all 90.70 0.00 9.30 0.00 0.00 0.00 02:31:37 all 71.05 0.00 0.00 0.00 0.00 28.95 02:31:38 all 14.89 0.00 10.64 0.00 2.13 72.34 02:31:39 all 2.56 0.00 0.00 0.00 0.00 97.44 02:31:40 all 0.00 0.00 0.00 0.00 0.00 100.00 02:31:41 all 0.00 0.00 0.00 0.00 0.00 100.00 My suspicion that this comes from I/O related issue is also because a caching plugin I use to reduce the amount of queries to the database, by precompiling PHP pages is actually making things worse instead of better. It seems that file access is making things worse instead.

• AWS own email domain and some generic questions

  - by John Brunner

  I'm getting started with Amazon Web Services and I have a few question I'm not sure about. As every (company) webpage I want to use an "[email protected]" email adress, but how is that done? I looked up at godaddy.com (for domain registration), the offer me an email adress like I want, but for 3 dollars per month. Is this possible with AWS? Because at AWS you have just a complex domain which is not very userfriendly or serious. Also I want to host my dynamic webpage on the amazon cloud, but I'm not sure if I'm doing that right. I've read many guides, and all I know is that I have to purchase a Elastic Compute Cloud, and a Simple Storage Service... and every guide is working with the basic linux package, why not Windows? Is it more expensive? I just want to host a mySQL Server for the dynamic webpage, which is reached over a normal domain. And one last question, if I sign up for an AWS account it asks me for an email account. But I found it a little bit unserious to write there my free-webmailer-adress... How is it done the normal way? Thanks in advance! Best regards, john.

• Generic tool to configure startup applications on Unix

  - by srid

  Is there an automated deployment tool that manages startup applications on a variety of machines, especially the Unices? Or is the only hope to study the nuts and bolts of each Unix (osx, linux, solaris, hpux, aix) on how to configure applications to launch on system startup? I want to run them as a specific user, instead of root. At the moment, I run them all within a screen session .. which is a hassle, as this requires manual intervention every time the machine is rebooted for some reason. Ideally, I am looking for a tool that would read, say, ~/.startup-programs which file contains, on each line, the command line to launch the needed daemons. And this tool should work on OSX, Linux, Solaris, HPUX and AIX ... writing the appropriate startup scripts for each platform.

• On clients use generic driver for printer shared by CUPS

  - by Daniel

  I know this worked really easy with a recent CUPS version some years ago. Unfortunately I fail to do the following with latest CUPS nowadays. How to share a printer without using printer specific drivers on the clients with CUPS? The printer is a Samsung ML-2010. The important fact is that it needs a quite specific library for printing called splix. That is installed on the server and prints well. What makes trouble is using that printer over the network. I found out how to use Avahi under Linux to make use of DNSSD to advertise and discover printers. But as far as I understand the new CUPS offers the internal driver interface on the network. This has 2 major issues: anybody can fiddle with the driver and I don't trust any uncommon printer library to be "network secure" anyone who wants to use my printer including guests needs to install the specific drivers first I remember the old days when I could enable "Share this printer" on the CUPS server and all clients would magically detect the printer and just send their job data to the server and have it do the driver stuff. After everything a read I guess this is related to the changes Apple introduced with CUPS including dropping of the integrated network discovery protocol. If it helps: Server: Ubuntu LTS 12.04 Server with CUPS 1.5.3 Client: Arch Linux with current CUPS 1.6.1 On another box with Ubuntu the printer was setup automatically at least but the mechanism used the Splix library for that.

• Stop that programming from running when i plug in my iPhone

  - by codingguy3000

  I know that this is not exactly a programming question, but this is pretty geeky stuff so please don't vote me down. When ever I plug in my iPhone into my work computer Word 2007 decides it wants to start up. How do I make it stop? Is it a registry deal, or is there an windows interface that I'm unaware of. I'm on Win XP SP3 by the way. Thanks

• How to choose an integer linear programming solver ?

  - by Cassie

  Hi all, I am newbie for integer linear programming. I plan to use a integer linear programming solver to solve my combinatorial optimization problem. I am more familiar with C++/object oriented programming on an IDE. Now I am using NetBeans with Cygwin to write my applications most of time. May I ask if there is an easy use ILP solver for me? Or it depends on the problem I want to solve ? I am trying to do some resources mapping optimization. Please let me know if any further information is required. Thank you very much, Cassie.

• Is Programming == Math?

  - by moffdub

  I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection. Aside from some obvious examples: using induction to prove a recursive algorithm formal correctness proofs functional languages lambda calculus asymptotic complexity DFAs, NFAs, Turing Machines, and theoretical computation in general the fact that everything on the box is binary In what ways is programming really a subset of math? I'm looking for an explanation that might have relevance to enterprise/OO development (if there is a strong enough connection, that is). Thanks in advance. Edit: as I stated in a comment to an answer, math is uber important to programming, but what I struggle with is the "subset" argument.

• Algorithm and data structure learning resources for dynamic programming

  - by Pranav

  Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

• Best resource for serious Commodore 64 programming.

  - by postfuturist

  What is the best resource for serious Commodore 64 programming? Assume that serious programming on the Commodore 64 is not done in BASIC V2 that ships with the Commodore 64. I feel like most of the knowledge is tied up in old books and not available on the internet. All that I have found online are either very beginner style introductions to Commodore 64 programming (Hello world), or arcane demo-coder hacks to take advantage of strange parts of the hardware. I haven't found a well-explained list of opcodes, memory locations for system calls, and general mid-level examples and tips. Main portals I have found: lemon64 C-64 Scene Database c64web Actually hosted on a Commodore 64! Tools I have found: cc65 A C compiler that can target Commodore 64.

• Why do you enjoy programming?

  - by Earlz

  Some of us here(or is it just me?) enjoy programming. Even if we're not being paid for it, and in some cases, even though the end result will not do anything for us. For example, many people do the Project Euler problems just for fun, and in the end nothing was really "accomplished" materially. What is it that makes us enjoy programming? How is programming different from another job? You don't see an accountant going home to do some accounting on their own time just for the pure joy of it. How are we different? (also, if anyone has some ideas on how to tag this, then please do correct it for me.. )

• Becoming a professional programmer / software engineer

  - by Matt

  This isn't strictly about programming, more about being a programmer, so I'm sorry if its not the right kind of question to ask on this forum (mod, please delete if it isn't) I'm a computer tech in the US Army, and once I'm out I'll have eight years on the job. I'm about to start a degree through an online school (the only way I can get the army to pay for it while I'm still in), and I'm seriously looking at getting a computer science degree. I'm great with computers. I can take one apart and put it back together with my eyes closed. I'm A+ and Network+ certified and I'm getting a couple other CompTIA certs before I get out. I can work Windows as well as anyone on this planet and I'm not terrible with Linux. A job in computers is something I've always wanted. But, aside from being a computer technician, it seems that every job in the field requires programming ability. I like programming as a hobby. I programmed TI BASIC in high school and I'm teaching myself Python, but that's as far as my experience goes. That sort of brings me to my questions: I've always heard that the first language is the most difficult, and once you learn it well then all the others sort of fall into place for you. Is that true? Like, if I spend the next eight months mastering Python, will I pretty much be able to pick up at least fair proficiency in any other OO language within a month of studying it or whatever? How easy is it to burn out? the biggest thing I'm afraid of is just burning out on programming. I can go all day long if I'm programming strictly for my own personal desire, but I can imagine it being really easy to burn out after a few years of programming to deadlines and certain specifications. Especially if its a big project involving a dozen different designers. From what I told you about myself, would I already be qualified to work as a regular technician (geek squad type or maybe running a computer repair shop). Is Python a good base to learn from? I've heard that it makes you hate other languages because they feel more convoluted when learning, but also that its a great beginner language. If you're a professional programmer, did you have any of the same fears? Would you recommend that I stick to computer repair and Python rather than try to get into corporate programming? (just from what you've read in this thread, anyway) Thanks for taking the time to read all this and answer (if you did)

• How do I find/make programming friends?

  - by Anton

  I recently got my first programming internship and was extremely excited to finally be able to talk with and interact with fellow programmers. I had this assumption that I would find a bunch of like minded individuals who enjoyed programming and other aspects of geek culture. Unfortunately, I find myself working with normal people who program for a living and never discuss or show interest in programming outside of their work. It is incredibly disappointing, because I do think one of the best ways to progress in life and as a programmer is to talk about what you enjoy with others and to build bonds with people who enjoy similar things. So how do I go about finding/making programmer friends?

• Choice of programming language for learning data structures and algorithms

  - by bguiz

  Which programming language would you recommend to learn about data structures and algorithms in? Considering the follwing: Personal experience Language features (pointers, OO, etc) Suitability for learning DS & A concepts I ask because there are some books out there that are programming language-agnostic (written from a Mathematical perspective, and use pseudocode). If I learn from one of these I would like to work out the algorithms in a chosen language. Then, there are other books which introduce DS & A concepts with examples in a particular programming laguage - and I would follow these examples as well. Either way, I have to choose a language, and I would like to stick to one throughout. Which one best fits the bill.

• Common Programming Jargon

  - by jdk

  What programming terms have you coined (or heard) that have taken off in your own circles (i.e. have heard others repeat it)? It might be within your own team, workplace or garnered greater popularity on the Internet. Write your programming term, word or phrase in bold text followed by an explanation, citation and/or usage example so we can use it in appropriate context. Please no repeats of common jargon already ingrained in the programming culture like: "kludge", "automagically", "cruft", etc. (unless you coined it). Stealing from the comments: "A shared vocabulary is the basis of communication, not just among programmers [...]"

• Programming language for fast calculations with big integers

  - by sub

  I'm doing Project Euler problems at the moment and I can solve most of them using my own programming language which uses direct C++ integers (so they are bound to 2^32 on my machine). However, at times there are problems which require me to work with very high numbers, I can't do that with native integers. So I implemented a BigInt library in my language which unfortunately gets extremely slow at times. Is there a programming language suitable for very efficient handling of big numbers? I mean that I want to do the things I could do in other programming languages with it (variables, loops, etc.), but in a faster way. If you have got tips for workarounds of the 2^32 limit in my language/C++/other languages, please tell me too!

• In game programming are global variables bad?

  - by Joe.F

  I know my gut reaction to global variables is "badd!" but in the two game development courses I've taken at my college globals were used extensively, and now in the DirectX 9 game programming tutorial I am using (www.directxtutorial.com) I'm being told globals are okay in game programming ...? The site also recommends using only structs if you can when doing game programming to help keep things simple. I'm really confused on this issue, and all the research I've been trying to do is very confusing. I realize there are issues when using global variables (threading issues, they make code harder to maintain, the state of them is hard to track etc) but also there is a cost associated with not using globals, I'd have to pass a loooot of information around very often which can be confusing and I imagine time-costing, although I guess pointers would speed the process up (this is my first time writing a game in C++.) Anyway, I realize there is probably no "right" or "wrong" answer here since both ways work, but I want my code to be as proper as I can so any input would be good, thank you very much!

• Approaches to a week long camp programming course (tips & projects)

  - by Good Person

  I will be teaching a week long programming course to kids between the ages of 11-18. Most of the kids have no programming experience. I'm looking for two things 1) General tips for teaching a camp class (how to make it fun when explaining the difference between int and float) 2) Interesting projects that the kids will be able to complete by the end of the week. Unfortunately the language I'll be required to use is either c++ or Java which means that I'll need to spend more time on itty bitty details than I'd like in a week long course. I feel more competent in c++ than in Java. However if someone can show me that Java is much easier to learn I'll probably teach that instead. My initial idea is to try something like "a game a day" with games like hangman, tic-tac-toe, guess-a-number, wheel-of-fortune, etc. I'll try and update the question text as answers come in to offer more details While there are other questions about teaching programming around I'm looking for advice and tasks that are useful for specifically a week long camp

• Mathematics and Game Programming

  - by Xfcn

  I want to program graphical 2D games more complex than the basic 2D stuff I already know. I don't want to do 3D programming. Just more complex 2D stuff. I dropped high school before I could learn a lot of stuff so I walked away with enough algebra knowledge to balance my checkbook and do some light 2D Cartesian programming. Are there any good resources out there for a guy with a limited attention span (say 20 minutes apiece for a subject I'm keenly interested in) to learn, gradually, how to do something more useful with math in programming?
