  • Dealing with Fanboys

    - by jozefg
    We've all probably met someone like this, that developer who just knows that his language is the one true language and won't shut up about it. How do you deal like someone like this? I don't want to offend anyone (especially since the fanboy in my workplace is the senior developer). But I want to be able to use my own choice of scripting language when I have to write a throwaway script that never makes it to the repository and no one else need know existed. Thoughts that I had to dealing with this: Laugh it off - "Haha yeah maybe language X is a bit easier, I guess I'm a masochist!" Go with it - I'd really prefer to avoid this as I can't afford the drop in productivity associated with picking up a new language. Hide my language - Become a closet programmer and hide my monitor whenever I'm scripting or automating something. What would you suggest for this situation?

  • Language Design: Combining Gotos and Functions

    - by sub
    I'm designing and currently rethinking a low-level interpreted programming language with similarities to assembler. I very soon came across the functions/loops/gotos decision problem and thought that while loops like while and for would be too high-level and unfitting, gotos would be too low level, unmaintainable and generally evil again. Functions like you know them from most languages that have return values and arguments aren't fitting in the language's concept either. So I tried to figure out something between a function and a goto which is capable of Recursion Efficient loops After some thinking I came up with the idea of subroutines: They have a beginning and an end like a function They have a name but no arguments like a goto You can go into one with jump and go out of it again before its end with return (doesn't give back any result, only stops the subroutine) Handled just like normal code - Global scope like goto So I wanted to know: Is the idea above good? What are the (dis)advantages? Would there be a better combination of function and goto or even a completely new idea?

  • Programming Constructs History

    - by kunjaan
    I need some help in figuring out which language introduced the constructs that we use everyday. For example: Constructs Introduced from LISP If-Else Block :"The ubiquitous if-then-else structure, now taken for granted as an essential element of any programming language, was invented by McCarthy for use in Lisp, where it saw its first appearance in a more general form (the cond structure). It was inherited by Algol, which popularized it. " - WikiPedia Function Type : Functions as first class citizens. Garbage Collection

    - by Sean
    hi all last week i distributed my first app to the appstore. what i've to see was, that the app language which is shown in appstore is not the right one. my app is just in german, but in appstore english is shown up. can somebody tell me what i've exactly got to do, that the language in the appstore is german? i know i ned a "de.lproj" folder, but i don't know what this folder should contain and what i've got to do step by step to realize that the right way. thanks in advance sean

  • How to determine user's language setting from LocalSystem

    - by Louis
    I have a Windows system service that needs to communicate string information to an application running under the user's account. The strings will appear to the user so I want to make sure that the strings that the service passes to the application are in the same language as the user account. How can I tell what display language the currently logged in user has from the service code? If I can determine this, I can just load the correct resource file and be done. I don't have to support multiple user's logged in so the service will only communicate with one application instance at a time.

  • Parsing language for both binary and character files

    - by Thorsten S.
    The problem: You have some data and your program needs specified input. For example strings which are numbers. You are searching for a way to transform the original data in a format you need. And the problem is: The source can be anything. It can be XML, property lists, binary which contains the needed data deeply embedded in binary junk. And your output format may vary also: It can be number strings, float, doubles.... You don't want to program. You want routines which gives you commands capable to transform the data in a form you wish. Surely it contains regular expressions, but it is very good designed and it offers capabilities which are sometimes much more easier and more powerful. Something like a super-grep which you can access (!) as program routines, not only as tool. It allows: joining/grouping/merging of results inserting/deleting/finding/replacing write macros which allows to execute a command chain repeatedly meta-grouping (lists-tables-hypertables) Example (No, I am not looking for a solution to this, it is just an example): You want to read xml strings embedded in a binary file with variable length records. Your tool reads the record length and deletes the junk surrounding your text. Now it splits open the xml and extracts the strings. Being Indian number glyphs and containing decimal commas instead of decimal points, your tool transforms it into ASCII and replaces commas with points. Now the results must be stored into matrices of variable length....etc. etc. I am searching for a good language / language-design and if possible, an implementation. Which design do you like or even, if it does not fulfill the conditions, wouldn't you want to miss ? EDIT: The question is if a solution for the problem exists and if yes, which implementations are available. You DO NOT implement your own sorting algorithm if Quicksort, Mergesort and Heapsort is available. You DO NOT invent your own text parsing method if you have regular expressions. You DO NOT invent your own 3D language for graphics if OpenGL/Direct3D is available. There are existing solutions or at least papers describing the problem and giving suggestions. And there are people who may have worked and experienced such problems and who can give ideas and suggestions. The idea that this problem is totally new and I should work out and implement it myself without background knowledge seems for me, I must admit, totally off the mark.

  • Primary reasons why programming language runtimes use stacks?

    - by manuel aldana
    Many programming language runtime environments use stacks as their primary storage structure (e.g. see JVM bytecode to runtime example). Quickly recalling I see following advantages: Simple structure (pop/push), trivial to implement Most processors are anyway optimized for stack operations, so it is very fast Less problems with memory fragmentation, it is always about moving memory-pointer up and down for allocation and freeing complete blocks of memory by resetting the pointer to the last entry offset. Is the list complete or did I miss something? Are there programming language runtime environments which are not using stacks for storage at all?

  • How to create a language these days?

    - by Mike
    I need to get around to writing that programming language I've been meaning to write. How do you kids do it these days? I've been out of the loop for over a decade; are you doing it any differently now than we did back in the pre-internet, pre-windows days? You know, back when "real" coders coded in C, used the command line, and quibbled over which shell was superior? Just to clarify, I mean, not how do you DESIGN a language (that I can figure out fairly easily) but how do you build the compiler and standard libraries and so forth? What tools do you kids use these days?

  • Do you use another language instead of english ?

    - by Luc M
    Duplicate Should identifiers and comments be always in English or in the native language of the application and developers? For people who are not native English speakers, which language do you use to declare variables, classes, etc. ? I had to continue a project from a Spanish guy. Everything was written in Spanish. Since this time, I have decided to use English identifiers ( variables, classes, file names) and write comments in french. Everything was in french before that. What are the general recommendations about that practice? Do you use English everywhere knowing that no English people will work on your project ? Edit : Here's a post from Jeff Atwood about this subject: The Ugly American Programmer

  • making a programming language

    - by None
    I was wondering which way would create a faster programming language, because I have tried both. Writing code that takes the text, splits it by whitespace or newlines or something, then processes each line and has a dictionary for variables. Or writing code that takes text and converts it to another programming language. This is an example of how a very simple version of the first way would be programmed in python: def run(code): text = code.split(";") for t in text: if t == "hello": print "hi" second: def run(code): rcode = "" text = code.split(";") for t in text: if t == "hello": rcode += "print 'hi'"

  • FluentPath: a fluent wrapper around System.IO

    .NET is now more than eight years old, and some of its APIs got old with more grace than others. System.IO in particular has always been a little awkward. Its mostly static method calls (Path.*, Directory.*, etc.) and some stateful classes (DirectoryInfo, FileInfo). In these APIs, paths are plain strings. Since .NET v1, lots of good things happened to C#: lambda expressions, extension methods, optional parameters to name just a few. Outside of .NET, other interesting things happened as well. For...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • EPM 11.1.2 - In WebLogic Server, Enable Native IO Performance Pack

    - by Ahmed Awan
    Performance can be improved by enabling native IO in production mode. WebLogic Server benchmarks show major performance improvements when native performance packs are used on machines that host Oracle WebLogic Server instances. Important Note:  Always enable native I/O, if available, and check for errors at startup to make sure it is being initialed properly. Tip: The use of NATIVE performance packs are enabled by default in the configuration shipped with your distribution. You can use the Administration Console to verify that performance packs are enabled by clicking on each managed server and click on Tuning tab.

  • T-SQL Tuesday - IO capacity planning

    - by Michael Zilberstein
    This post is my contribution to Adam Machanic's T-SQL Tuesday #004 , hosted this time by Mike Walsh . Being applicative DBA, I usually don't take part in discussions which storage to buy or how to configure it. My interaction with IO is usually via PerfMon. When somebody calls me asking why everything is suddenly so slow on database server, "disk queue length" or "average seconds per transfer" counters provide an overwhelming answer in 60-70% of such cases. Sometimes it can be...(read more)

  • Python to MATLAB: exporting list of strings using scipy.io

    - by user292461
    I am trying to export a list of text strings from Python to MATLAB using scipy.io. I would like to use scipy.io because my desired .mat file should include both numerical matrices (which I learned to do here) and text cell arrays. I tried: import scipy.io my_list = ['abc', 'def', 'ghi'] scipy.io.savemat('test.mat', mdict={'my_list': my_list) In MATLAB, I load test.mat and get a character array: my_list = adg beh cfi How do I make scipy.io export a list into a MATLAB cell array?

  • Learning language is enough to create average applications ?

    - by Freshblood
    Many books teach a programming language. However, knowing a specific language is not the same as knowning application or GUI design nor project layout. So, attempting to make an average application fails after learning a language. It is clear that knowing a language is not enough to make an application. If you agree with what I have said, why doesn't anyone mention this instead of teaching pure language syntax and features? Why books don't mention how to make a better application ?

  • Strange display language in gnome shell

    I logged in gnome-shell, and found that the display language is set to some strange asian language (I think) without my prompt. I tried to change the locale settings but found that the default language is English (how?) despite of that strange language. Here's a snapshot, See the strange word instead of "Activity": I'm on Ubuntu 12.04 LTS.

  • how to really master a programming language

    - by cprogcr
    I know that learning a language, you can simply buy a book, follow the examples, and whenever possible try the exercises. But what I'm really looking is how to master the language once you've learned it. Now I know that experience is one major factor, but what about learning the internals of the language, what is the underlying structure, etc. There are articles out there saying read this book, read that book, make this game and that game. But to me this doesn't mean to master a language. I want to be able to read other people's code and understand it, no matter how hard that is. To understand when to use a function and when another, etc etc. The list could go on and on but I believe I've made the point. :) And finally, take whatever language as an example if needed, though best would be if C was taken as an example.
