  • Can we write an EOF character ourselves?

    - by Apoorv
    Most of the languages like C++ when writing into a file, put an EOF character even if we miss to write statements like : filestream.close However is there any way, we can put the EOF character according to our requirement, in C++, for an instance. Or any other method we may use apart from using the functions provided in C++. If you need to ask more of information then kindly do give a comment. Thanks in advance.

  • Do Java or C++ lack any OO features?

    - by tsv
    I am interested in understanding object-oriented programming in a more academic and abstract way than I currently do, and want to know if there are any object-oriented concepts Java and C++ fail to implement. I realise neither of the languages are "pure" OO, but I am interested in what (if anything) they lack, not what they have extra.

  • Where is Prolog used for traffic control systems?

    - by Masi
    The user Laurent had an interesting reply to the question [Why hasn’t logic programming caught on?]: If you look at the influence logic-programming has had in the field of -- air traffic control -- I don't think it can be said logic-programming has not caught on. A question arises: Where is prolog used for traffic control systems on the roads? Why is it used instead of languages, such as C or Python, in such environments?

  • Separating a group of functions into an includable file in C?

    - by zebra
    I know this is common in most languages, and maybe in C, as well. Can C handle separating several functions out to a separate file and having them be included? The functions will rely on other include files, as well. I want the code to retain all functionality, but the code will be reused in several C scripts, and if I change it once I do not wish to have to go through every script and change it there, too.

  • Sending / Forwarding variable arguments in ObjectiveC

    - by Authman Apatira
    I know this is possible in other programming languages. Suppose we have the following arrangement: - (void) myMethod:(NSString*)variables, ... { // Handle business here. } - (void) anotherMethod:(NSString*)variables, ... { // We want to pass these variable arguments for handling [self myMethod:variables, ...]; // Do not pass GO } // Start the party: [self anotherMethod:@"arg1", @"arg2", @"arg3", @"arg4", nil]; What's the trick to get this working in ObjC?

  • I'm still learning OOP. Any tips on staying unbiased and pragmatic?

    - by marcdev
    I keep reading about defficiencies and issues with languages. Specifically, I'm learning PHP and Javascript, but I see it everywhere. This question arose while reading Javascript: The Good Parts and PHP Objects, Patterns and Practice. While understanding and avoiding easy pitfalls, is there a way I can learn the fundamentals of OOP and discover solid programming practices without overlooking important areas (or simply becoming jaded)? I'm sure I'll have plenty of opportunity to learn from mistakes!

  • Learning C++ on Linux or Windows?

    - by ReDAeR
    Hi, Since you 'should' learn C/C++ and as part of 'learn as much languages as possible', i decided to learn C++ in depth. My OS is Windows and my question is should i re-install Linux as a dual boot to learn C++ on Linux? Do i miss something if I develop in C++ only on the Windows platform? (possible duplicate: http://stackoverflow.com/questions/1128050/best-operating-system-for-c-development-and-learning)

  • pfSense Firewall or Linsys/Cisco router for small offices

    - by Tim Meers
    I'm about to start switching some networks around for multiple small offices. Each office has about 10 to 15 users and 10 to 15 computers. Each office has a spread of generic routers and access points. The routers vary from being used as routers, to just being an access point for wireless. Nothing formal has really ever beem implemented for each of the 10 offices. What I'm wanting is to set up a pfSense box for each office to configure things like: traffic shaping (for VoIP QOS) URL Filtering DHCP static routing multiple VLANs I'll then use some of the existing hardware for wireless. Maybe even integrate the wireless right into the firewall depending on the office layout. So my question, would this be better to do a full blown firewall box, or but a new business class or high end consumer class Linksys router to do the URL filtering, QOS and DHPC? Each option could allow for remote access and VPN for remote maintnance and each would only cost a nominal about of money for something decent, i.e. under $250.

  • Cannot get libcurl-devl on OpenSUSE 11.3

    - by Dai
    I have a server running OpenSUSE 11.3 that I can't really upgrade to a newer version of OpenSUSE (it's a managed appliance). I have some PHP shell scripts that need to run on the server that have a dependency on both cURL and OpenSSL. I discovered that the PHP 5.3.3 binaries on the server did not include OpenSSL but did include cURL I downloaded the latest PHP sources, extracted them, and ran ./configure --with-openssl --with-zlib --with-bcmath --with-curl --with-readline --with-libxml --enable-sockets This failed: the configure script complained that it couldn't find cURL: checking for cURL support... yes checking for cURL in default path... not found configure: error: Please reinstall the libcurl distribution - easy.h should be in /include/curl/ I tried to install libcurl by running zypper install libcurl-devl This failed too: doom:~/phpworksite/php-5.5.15 # zypper install libcurl-devl Loading repository data...

  • How to load the environment variables at boot time before X11 on Ubuntu Precise?

    - by Fnux
    Using Ubuntu Precise 64 bit, I'm facing a problem that I'm unable to solve and that I'll try to describe below: I'm using a console mode program (let's say abc) that uses Go, NodeJS, Java and Scala. In order for abc to work with these languages, I've to declare the following statements: a) within /etc/environment: PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin" CLASSPATH=$CLASSPATH:/usr/share/java/scala-library.jar b) within /etc/login.defs ENV_SUPATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin ENV_PATH PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin c) a) within /etc/sudoers: `# env_reset Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin"` Then, when I start abc from a terminal, all is fine and I can use any of the 4 languages described above. However, if I put a script within /etc/init.d that starts abc during the boot process (i.e. before to start the GUI), using Java from abc still is fine, but using Go, NodeJS or Scala doesn't work anymore. Then, I guess that during the boot process, the script within /etc/init.d that starts abc is executed before that the different environment variables set within /etc/sudoers, /etc/environment and /etc/login.defs are loaded. So, my question is: how to force the environment variables to be loaded before that my script starting abc is launched? Any help and advice on this topic would be trully appreciated. TIA. Cheers. Thanks again to Mark and Danila. Below is the current "abc" script file that I put within /etc/init.d `#! /bin/sh ### EDIT: ADD THIS VARS DEFINITIONS: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin" CLASSPATH=$CLASSPATH:/usr/share/java/scala-library.jar "ENV_SUPATH PATH"="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin" "ENV_PATH PATH"="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin" "Defaults secure_path"="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin" ##### EXPORT this VARS so they are accessible to children:" export "PATH" "CLASSPATH" "ENV_SUPATH PATH" "ENV_PATH PATH" "Defaults secure_path" `### BEGIN INIT INFO `# Provides: abc `# Required-Start: $remote_fs $syslog `# Required-Stop: $remote_fs $syslog `# Default-Start: 2 3 4 5 `# Default-Stop: 0 1 6 `# Short-Description: abc initscript `# Description: This iniscript starts and stops abc `### END INIT INFO `# Author: Fnux, fnux.fl at gmail dot com `# Version: 1.2 `# Note: (edit ABC_PATH if abc isn't installed in /opt/abc) NAME=abc ABC_PATH=/opt/abc START="-d" STOP="-k" VERSION="-v" SCRIPTNAME=/etc/init.d/$NAME STARTMESG="\nStarting abc in deamon mode."

  • The physical working paradigm of a signal passing on wire.

    - by smwikipedia
    Hi, This may be more a question of physics, so pardon me if there's any inconvenience. When I study computer networks, I often read something like this in order to represent a signal, we place some voltage on one end of the wire and the other end will detect the voltage and thus the signal. So I am wondering how a signal exactly passes through wire? Here's my current understanding based on my formal knowledge about electronics: First we need a close circuit to constrain/hold the electronic field. When we place a voltage at somewhere A of the circuit, electronic field will start to build up within the circuit medium, this process should be as fast as light speed. And as the electronic field is being built up, the electrons within the circuit medium are moved, and thus electronic current occurs, and once the electronic current is strong enough to be detected at somewhere else B on the complete circuit, then B knows about what has happend at A and thus communication between A and B is achieved. The above is only talking about the process of sending a single voltage through wire. If there's a bitstream and we need to send a series of voltages, I am not sure which of the following is true: The 2nd voltage should only be sent from A after the 1st voltage has been detected at B, the time interval is time needed to stimulate the electronic field in the medium and form a detectable electronic current at B. Several different voltages could be sent on wire one by one, different electronic current values will exists along the wire simutaneously and arrive at B successively. I hope I made myself clear and someone else has ever pondered this question. (I tag this question with network cause I don't know if there's a better option.) Thanks, Sam

  • can't properly shutdown ubuntu and sound problem on HP mini 311 netbook

    - by Viele
    hi, I recently bought a HP mini 311 netbook. I replaced its harddrive and installed ubuntu 10.04. Since then, I have encountered some very strange problem with its sound and shutdown/reboot. At times, when I start the computer, it will have no sound, on the GUI the sound is at max, but no sound is available. This sometimes also happen after after upgrades, hibernate, and toggling the wireless radio button. Strangely, when the sound is out the device will also refuse to be shutdown. If I shutdown the computer using the GUI, it will simply go back to the log in screen without actually shutting down. If I use "sudo shutdown 0", the computer will hang on the loading screen of the shut down process. I had to force the pc to shutdown by holding the power button down. usually (probably always) after I force a turn-off then start off again. the sound and shutdown become normal. I wonder if anyone have clues regarding to the cause of this problem. This the info about the computer: 1) installed ubuntu 10.04LTS RC, later upgraded to formal released version. 2) cat /proc/asound/version == "Advanced Linux Sound Architecture Driver Version 1.0.21." however, when doing 'alsaconf' the version displayed is 1.0.23 any help is appreciated. Thanks

  • What are best practices on virtual lab/test bed architecture?

    - by WooYek
    I am currently preparing a new small virtual environment for development and testing with Windows Server + SQL Server + AD + Sharepoint + Exchange + IIS(ASP.NET) + Biztalk + ?, for a small (up to 5) dev team. What are pros and cons on different approaches, eg. splitting up over different machines or packing everything up per machine. I your experience what are the best practices I should follow in terms of architecture and various system/servers placement. What to share and what to split per person. I would like to achieve some flexibility for the dev and testing process (so teammebers would not be steeping on each other's toes) and limit administrative effort needed to propagate settings, integrate work items and revert changes when something breaks up. It's not supposed to be an everyday development working environment, more a tier 2 developer testing environment, and not yet an integration or QA testing environment with formal change process. IMO the two borderline solutions are: creating one all-inclusive machine for each dev team member giving them freedom to manage creating shared environment managed by the one with somehow formalized change request process What golden mean would you recommend, and why?

  • Vim: Context sensitive code completion for PHP

    - by eddy147
    Vim gives me too much options when I use code completion. In a class, and type $class- it gives me about a zillion options, so not only from the class itself but also from php, all globals ever created, in short: a mess. I only want to have the options from the class itself (or the parent subtype class it extends from), so context or scope sensitive code completion, just like Netbeans for example. How can I do that? My current configuration is this: I am using ctags, and created 1 ctags file for our (big) application in the root. This is the .ctags file I used to create the ctags file: -R -h ".php" --exclude=.svn --languages=+PHP,-JavaScript --tag-relative=yes --regex-PHP=/abstract\s+class\s+([^ ]+)/\1/c/ --regex-PHP=/interface\s+([^ ]+)/\1/c/ --regex-PHP=/(public\s+|static\s+|protected\s+|private\s+)\$([^ \t=]+)/\2/p/ --regex-PHP=/const\s+([^ \t=]+)/\1/d/ --regex-PHP=/final\s+(public\s+|static\s+|abstract\s+|protected\s+|private\s+)function\s+\&?\s*([^ (]+)/\2/f/ --PHP-kinds=+cdf --fields=+iaS This is the .vimrc file: " autocomplete funcs and identifiers for languages autocmd FileType php set omnifunc=phpcomplete#CompletePHP autocmd FileType python set omnifunc=pythoncomplete#Complete autocmd FileType javascript set omnifunc=javascriptcomplete#CompleteJS autocmd FileType html set omnifunc=htmlcomplete#CompleteTags autocmd FileType css set omnifunc=csscomplete#CompleteCSS autocmd FileType xml set omnifunc=xmlcomplete#CompleteTags autocmd FileType php set omnifunc=phpcomplete#CompletePHP autocmd FileType c set omnifunc=ccomplete#Complete " exuberant ctags " the magic is the ';' at end. it will make vim tags file search go up from current directory until it finds one. set tags=projectrootdir/tags; map <F8> :!ctags " TagList " :tag getUser => Jump to getUser method " :tn (or tnext) => go to next search result " :tp (or tprev) => to to previous search result " :ts (or tselect) => List the current tags " => Go back to last tag location " +Left click => Go to definition of a method " More info: " http://vimdoc.sourceforge.net/htmldoc/tagsrch.html (official documentation) " http://www.vim.org/tips/tip.php?tip_id=94 (a vim tip) let Tlist_Ctags_Cmd = "~/bin/ctags" let Tlist_WinWidth = 50 map <F4> :TlistToggle<cr> "see http://vim.wikia.com/wiki/Make_Vim_completion_popup_menu_work_just_like_in_an_IDE " will change the 'completeopt' option so that Vim's popup menu doesn't select the first completion item, but rather just inserts the longest common text of all matches :set completeopt=longest,menuone " will change the behavior of the <Enter> key when the popup menu is visible.

  • C# in Depth, Third Edition by Jon Skeet, Manning Publications Co. Book Review

    - by Compudicted
    Originally posted on: http://geekswithblogs.net/Compudicted/archive/2013/10/24/c-in-depth-third-edition-by-jon-skeet-manning-publications.aspx I started reading this ebook on September 28, 2013, the same day it was sent my way by Manning Publications Co. for review while it still being fresh off the press. So 1st thing – thanks to Manning for this opportunity and a free copy of this must have on every C# developer’s desk book! Several hours ago I finished reading this book (well, except a for a large portion of its quite lengthy appendix). I jumped writing this review right away while still being full of emotions and impressions from reading it thoroughly and running code examples. Before I go any further I would like say that I used to program on various platforms using various languages starting with the Mainframe and ending on Windows, and I gradually shifted toward dealing with databases more than anything, however it happened with me to program in C# 1 a lot when it was first released and then some C# 2 with a big leap in between to C# 5. So my perception and experience reading this book may differ from yours. Also what I want to tell is somewhat funny that back then, knowing some Java and seeing C# 1 released, initially made me drawing a parallel that it is a copycat language, how wrong was I… Interestingly, Jon programs in Java full time, but how little it was mentioned in the book! So more on the book: Be informed, this is not a typical “Recipes”, “Cookbook” or any set of ready solutions, it is rather targeting mature, advanced developers who do not only know how to use a number of features, but are willing to understand how the language is operating “under the hood”. I must state immediately, at the same time I am glad the author did not go into the murky depths of the MSIL, so this is a very welcome decision on covering a modern language as C# for me, thank you Jon! Frankly, not all was that rosy regarding the tone and structure of the book, especially the the first half or so filled me with several negative and positive emotions overpowering each other. To expand more on that, some statements in the book appeared to be bias to me, or filled with pre-justice, it started to look like it had some PR-sole in it, but thankfully this was all gone toward the end of the 1st third of the book. Specifically, the mention on the C# language popularity, Java is the #1 language as per https://sites.google.com/site/pydatalog/pypl/PyPL-PopularitY-of-Programming-Language (many other sources put C at the top which I highly doubt), also many interesting functional languages as Clojure and Groovy appeared and gained huge traction which run on top of Java/JVM whereas C# does not enjoy such a situation. If we want to discuss the popularity in general and say how fast a developer can find a new job that pays well it would be indeed the very Java, C++ or PHP, never C#. Or that phrase on language preference as a personal issue? We choose where to work or we are chosen because of a technology used at a given software shop, not vice versa. The book though it technically very accurate with valid code, concise examples, but I wish the author would give more concrete, real-life examples on where each feature should be used, not how. Another point to realize before you get the book is that it is almost a live book which started to be written when even C# 3 wasn’t around so a lot of ground is covered (nearly half of the book) on the pre-C# 3 feature releases so if you already have a solid background in the previous releases and do not plan to upgrade, perhaps half of the book can be skipped, otherwise this book is surely highly recommended. Alas, for me it was a hard read, most of it. It was not boring (well, only may be two times), it was just hard to grasp some concepts, but do not get me wrong, it did made me pause, on several occasions, and made me read and re-read a page or two. At times I even wondered if I have any IQ at all (LOL). Be prepared to read A LOT on generics, not that they are widely used in the field (I happen to work as a consultant and went thru a lot of code at many places) I can tell my impression is the developers today in best case program using examples found at OpenStack.com. Also unlike the Java world where having the most recent version is nearly mandated by the OSS most companies on the Microsoft platform almost never tempted to upgrade the .Net version very soon and very often. As a side note, I was glad to see code recently that included a nullable variable (myvariable? notation) and this made me smile, besides, I recommended that person this book to expand her knowledge. The good things about this book is that Jon maintains an active forum, prepared code snippets and even a small program (Snippy) that is happy to run the sample code saving you from writing any plumbing code. A tad now on the C# language itself – it sure enjoyed a wonderful road toward perfection and a very high adoption, especially for ASP development. But to me all the recent features that made this statically typed language more dynamic look strange. Don’t we have F#? Which supposed to be the dynamic language? Why do we need to have a hybrid language? Now the developers live their lives in dualism of the static and dynamic variables! And LINQ to SQL, it is covered in depth, but wasn’t it supposed to be dropped? Also it seems that very little is being added, and at a slower pace, e.g. Roslyn will come in late 2014 perhaps, and will be probably the only main feature. Again, it is quite hard to read this book as various chapters, C# versions mentioned every so often only if I only could remember what was covered exactly where! So the fact it has so many jumps/links back and forth I recommend the ebook format to make the navigations easier to perform and I do recommend using software that allows bookmarking, also make sure you have access to plenty of coffee and pizza (hey, you probably know this joke – who a programmer is) ! In terms of closing, if you stuck at C# 1 or 2 level, it is time to embrace the power of C# 5! Finally, to compliment Manning, this book unlike from any other publisher so far, was the only one as well readable (put it formatted) on my tablet as in Adobe Reader on a laptop.
