  • How to see "anti if" movement and its gaol?

    - by Vijay Shanker
    I have a developer for last 3 years, have been using if-else or if-else if statements a lot in my programing habit. And today, I found This link. One obvious sample i put here public void doSomthing(String target, String object){ //validate requests if(target != null && target.trim().length() < 1){ //invalid request; } //further logic } Now, I have seen this sort of check all over the places, libraries. So, I wanted to have a discussion about the worthiness of such a movement. Please let me know your views.

  • Simple way to print value of a register in x86 assembly.

    - by Bob
    I need to write a program in 8086 Assembly that receives data from the user, does some mathematical calculations and prints the answer on the screen, I have written all parts of the program and all work fine but I don't know how to print the number to the screen. At the end of all my calculation the answer is AX and it is treated as an unsigned 16 bit integer. How do I print the decimal (unsigned) value of the AX register?

  • Web Designer looking to learn back-end programming...

    - by Tabetha Moe
    Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

  • About first-,second- and third-class value

    - by forest58
    First-class value can be passed as an argument returned from a subroutine assigned into a variable. Second-class value just can be passed as an argument. Third-class value even can't be passed as an argument. Why should these things defined like that? As I understand, "can be passed as an argument" means it can be pushed into the runtime stack;"can be assigned into a variable" means it can be moved into a different location of the memory; "can be returned from a subroutine" almost has the same meaning of "can be assigned into a variable" since the returned value always be put into a known address, so first class value is totally "movable" or "dynamic",second class value is half "movable" , and third class value is just "static", such as labels in C/C++ which just can be addressed by goto statement, and you can't do nothing with that address except "goto" .Does My understanding make any sense? or what do these three kinds of values mean exactly?

    - by T. Schmidt
    Hi, not necessarily a programmer question but I need to enter a TAB after every 84th character of a text. I'm trying to do it in InDesign but I don’t see an option for this. Is there a good application to do this? Preferably Mac OS X compatlible but Windows XP is fine too. Thank you very much!

  • Programming introduction book

    - by Avi
    Hello there, I've offered an out-of-job girl to help her study programming (with an MCSD as the ultimate goal) - and she has no progrmming knowledge. The idea is that she'll study from books and I"ll help. Help- I need a gentle introduction to programming book, very easy, very practical, very hands-on and up to date. Optimally would be for the .Net 4.0 MS enviornment (C#,Visual Basic) but other alternaitves (Jave, Python etc.) are OK.

  • Parsing Domain From URL In PHP

    - by zuk1
    I need to build a function which parses the domain from a url. So: http://google.com/dhasjkdas/sadsdds/sdda/sdads.html or http://www.google.com/dhasjkdas/sadsdds/sdda/sdads.html Would become "google.com" and http://google.co.uk/dhasjkdas/sadsdds/sdda/sdads.html would become "google.co.uk"

  • how to start writing a very simple programming language

    - by Rex Homming
    Recently, I was going around looking for ideas on what I can build using C this summer and I came across this post: http://stackoverflow.com/questions/1257376/interesting-project-to-learn-c Implement a programming language. This doesn't have to be terribly hard - I did the language that must not be named - but it will force you to learn a lot of the important parts of C. If you don't want to write a lexer and/or parser yourself, you can use lex/flex and yacc/bison, but if you plan on that you might want to start with a somewhat smaller project. I was kinda intrigued about the implementing a programming language answer and I'm wondering how do I go about starting this? I've gone through the whole K&R book and I've done some of the exercises as well. I also have a bit of experience in C++ and Java if that matters. Any tips? Thanks!

  • Med-PC Programing Language

    - by mknuii
    There's this programing language called Med-PC that works with animal behavior. I'm trying to learn a bit about it, but i can't seem to find any kind of books or material about it. I've "google it" but all i seem to find are some references about it and a PDF explaining the installing of the program itself and sensors(for the experiments), not actual programing instructions. I'm looking for some kind of guidance, documents or books, some kind of reference where i can improve and learn about this language, or if it is based on some other language. I just need some reference about it. So i've resorted to StackOverFlow to see if anybody has worked, knows about it or can point me some links/books about it.

  • How can I call an executable to run on a separate machine within a program on my own machine (win xp

    - by Mr. H.
    My objective is to write a program which will call another executable on a separate computer(all with win xp) with parameters determined at run-time, then repeat for several more computers, and then collect the results. In short, I'm working on a grid-computing project. The algorithm itself being used is already coded in FORTRAN, but we are looking for an efficient way to run it on many computers at once. I suppose one way to accomplish this would be to upload a script to each computer and then run said script on each computer, all automatically and dependent on my own parameters. But how can I write a program which will write to, upload, and run a script on a separate computer? I had considered GridGain, but the algorithm is already coded and in a different language, so that is ruled out. My current guess at accomplishing this task is using Expect (wiki/Expect), but I have no knowledge of the tool. Any advice appreciated.

  • is php language C?

    - by avon_verma
    Ok: I edited my question: I heared somewhere, that php language is written by C. So i have question: what happens for example when you run a function in php such as date("Ymd"); or file_get_contents("file.txt");? Does it translate that code to C and request to server, or does php do it? sorry i haven't a clue And if it does translate it and request, that means besically it is C? sorry for english Thank you, Anon Verma

  • Getting started with MIT Proto

    - by Charles
    MIT Proto lacks a basic getting started guide. How do I find a shell that accepts commands like (def foo...) and proto -n 1000 -l -m ...? http://groups.csail.mit.edu/stpg/proto.html I can run in my bash shell: ./proto -n 1000 -s 0.1 -T -l "(red (gradient (= (mid) 0)))" I can't figure out how to run e.g. channel.proto: (def channel (src dst width) (let* ((d (distance src dst)) (trail (<= (+ (gradient src) (gradient dst)) (+ d 0.01))) ;; float error ;; (trail (= (+ (gradient src) (gradient dst)) d)) ) (dilate trail width))) ;; To see a channel calculated from geometric primitives, run: ;; proto -n 1000 -l -m -s 0.5 "(blue (channel (sense 1) (sense 2) 10))" ;; click on a device and hit 't' to set up the source, then click on ;; another device and hit 'y' to designate the destination. At first ;; every device will be blue, but then it should clear and you should ;; see a thick blue path connecting the two devices you selected. Thanks! P.S. Somebody please tag this mit-proto. I can't.

  • Use subform record set as domain argument in DAvg()

    - by harto
    Is it possible to use a subform's 'current' record set as the domain argument to DAvg() (etc.)? Basically, I have a subform that displays a subset of records from a query. I would like to run DAvg() over this subset. This is how I've gotten around it: =DAvg([FieldToAvg], [SubformQuery], "ChildField=Forms.MasterForm.MasterField And FieldToAvg > 0") but what I actually want is something like: =DAvg([FieldToAvg], [SubformCurrentlyDisplayedData], "FieldToAvg > 0") Is this possible in Access 2007?
