(it would have been 'void' in C) Done padma: http://www.ruby-lang.org/en/documentation/quickstart/ :) we're not going deep into ruby right now [22:40] harshitha : interactive ruby okay. why do we package applications? or libraries [22:41] oh ok :) *** monisha (~monisha@223.182.83.252) has joined channel #debian-diaspora so we can easily use simple functions instead of rewriting the code from scratch ? [22:42] harshi_PV: that is libraries right? [22:43] harshi_PV: ok lets start even more basic how do you install a software? apt-get :P dpkg -i click on exe?

I think we package to put relevant software and it's dependencies together so when you use the software,it just works fine. padma: okay same thing happens with exe I'm observing. :) i am thinking :P [22:46] aruna: you can join in :) i cant find the exe !!! I hope all of you have installed some software on windows so what happens when you click on a setup.exe? oh yes ...:) i loads the install wizard It starts installing the software [22:47] *** balasankarc (~balasanka@117.202.114.163) is now known as balasankarc|away padma: what all steps it does? EUlA padma: is it one click install or does it ask something? it installs all the dependencies needed to for that software [22:48] depends no? Ok so when you click th exe padma: ok take firefox as an example application the contents are getting installed. Many codes written get executed i think it links all the necessary files for a program to run am i right ? rharish: link means what? [22:49] padma: does firefox code get executed when you install firefox? imagineer: where does it get dependencies from? [22:50] no. It establishes an environment to run the browser. i meant .exe will execute a certain program to provide an output , not sure if link is what i wanted to use ... exe has links to look for dependencies [22:51] padma: what all does this exe file contain? binary codes pallavi: forget dependencies for a moment padma: what else? [22:52] it contains the binary of the application, neccessary documentation,license,icons,etc I dont't know j4v4m4n: The executable may have listed all the required packages, so one by one those list will be installed. just a guess. padma: see nitesh's answer :) yea got it okay [22:53] ok ok so "an installation program has the files required for an application and instructions to copy it to your computer" ok [22:54] ok so when we package we create a one file, like a zip or rar file which has all the files and instructions *** boutil_ (~boutil@mic92-3-81-56-66-213.fbx.proxad.net) has joined channel #debian-diaspora [22:55] there are different packaging format in gnu/linux, rpm and deb are common oh ok we will focus on deb what is rpm and deb , i forgot it :P [22:56] red hat package manager okay and instead of every package shipping an installation wizard, we have one program already installed that works like an installation wizard rharish: they are different formats similar to an exe or msi format in windows [22:57] okay how many of you have seen an msi file? me i have heard of it ... msi is microsoft installer format [22:58] Me can u give any examples if any ? where installation wizard is already there and package only has binaries okay rharish: some softwares are provided as msi [22:59] in case of deb format the installer is called dpkg and for rpm it is rpm dpkg and rpm are command like programs which understands rpm and deb format files okay ERC> /names [23:00] *** Users on #debian-diaspora: boutil_ monisha pallavi imagineer aruna harshi_PV padma gem nitesh balasankarc|away rharish swvist j4v4m4n jishnu7_ stultus Vivek antinooos boutil monisha: pallavi imagineer aruna harshi_PV padma rharish everyone clear so far? yup yes yes yep yea yes yes now about the dependency stuff [23:01] like someone already mentioned commnly used fucntions are distributed as a library which can be used in any application can any one give examples of libraries? libc [23:02] stdlib ?? just guessing :P [23:03] math and string libraries [23:04] when you write printf("hello world"), where is the code to actually print the output coming from? iostream ? no wait stidio' stdio iostream.h or stdio.h ? stdio stdio [23:05] stdio sure yes, it is part of the standard c library similarly there are libraries available for various commonly used tasks like compression, encryption, photo manipulation etc there are many libraries available to do the same task [23:06] what are they called? so when we write applications we use these libraries rather than write everything from scratch monisha: imagemagick is one library for photo manipulation oh okay okay openssl provides encryption libraries can we create our own library ?? [23:07] rharish: yes as we do in c prog ?? rharish: yes for eg monisha .. cimg is for image processing in C okay oh ok ok.. so when we package an application we have to say which all libraries it depend on [23:08] and we have to package each of these libraries if they are not already available is d sorry and we have programs like apt-get, aptitude, synaptic, software center which understand dependencies and use dpkg to install dependencies first [23:09] is there any standard library which v hav to use everywhere? monisha: there is nothing mandatory monisha: gnu c library is quite common for all c programs, which provides fucntions like printf and scanf ok okay [23:10] is it clear so far/ ? yea yes yeah yea yes yuo yea now when you say apt-get install chromium [23:11] what all happens in the background? *** nitesh_ (~nitesh@117.192.32.245) has joined channel #debian-diaspora no idea sorry can some one repeat the question, if there was a question asked? [23:12] now when you say apt-get install chromium what all happens in the background? okay It goes through sources.list to fetch it ? [23:13] so first it would probably search the local cache if such a software exists pallavi: okay what is sources.list? nitesh_: what is local cache? the place from where software should be downloaded Has list of links to repositories pallavi: what is a repository? [23:14] place where package is kept pallavi: where is that place? hard disk, dvd, usb drive? its a server server ubuntu server monstly a ftp [23:15] *mostly *** nitesh (~nitesh@117.192.39.153) has quit: Ping timeout: 480 seconds pallavi: where is that server, in your college lab? No :P in the server room [23:16] nitesh_: your college server room? or data center no saw one in iisc ok so there are repositories available on the internet [23:17] and you can setup local repositories as well and they are transferred using ftp? for example iit madras has a repository aruna: ftp or http aruna: there is even apt-torrent which uses bit torrent protocol okay , what exactly does ftp do ? or even http ? okay, j4v4m4n [23:18] debian/ubuntu etc has these repository copies in different countries we can choose a repository that is close to us or any one we want rharish, I *think* they are just a set of rules that say how files should be exchanged between computers rharish: they are protocols aruna: yup ftp is for transferring files [23:19] rharish: when we browse the internet we use http protocol who decides these protocols ? rharish: like when you type http://google.com you are telling your browser to use http protocol to connect to google.com rharish : A standards organisation? IEEE if I'm not wrong rharish: http is popularly used for websites [23:20] oh okay rharish: ftp is file transfer protocol usually if you have large files rharish: and https is for secure encrypted communications rharish: we are using irc protocol to chat padma: IETF rharish: https://en.wikipedia.org/wiki/Internet_Protocol#Version_history :) oh sorry :P padma: there are different standardization organizations [23:21] padma: some of them are IEEE standards like connecting via a serial port of your computer rharish: these are different ways of getting data from servers okay , thnks ok ok [23:22] okay so to summarise, we have collection of packages in repositories around the world a cdrom or dvd or usb drive or your hard disk can be a repository * stultus is Hrishikesh K B , basically from kerala. currently working in Bangalore. diaspora profile : https://joindiaspora.com/u/mehrishi (sorry for the delayed intro :P ) [23:23] every one open /etc/apt/sources.list using a text editor * j4v4m4n is http://joindiaspora.com/u/j4v4m4n * stultus is still at office. so won't able to attend the session. :'( ERC> /names *** Users on #debian-diaspora: nitesh_ boutil_ monisha pallavi imagineer aruna harshi_PV padma gem balasankarc|away rharish swvist j4v4m4n jishnu7_ stultus Vivek antinooos boutil done [23:24] monisha: pallavi imagineer aruna harshi_PV padma rharish everyone clear about repositories? yea yes harshi_PV: can you see repository names there? yes yup , opened it yup opened it! :) you can add or remove repositories there [23:25] yup , can be added well how do u open it ? gedit nano cat rharish: use a text editor gedit /etc/apt/sources.list on terminal type gedit /etc/apt/sources.list substitute gedit with nano or emacs or vi or vim [23:26] or gedit rharish: found it? found it ! thanks rharish: cool!

[23:44] padma: yes, luckily there is a tool called gem2deb which does most of the tasks for us [23:46] padma: and these are already packaged in a different format called gem [23:47] oh so it converts the scripts to packages right? padma: it convert a gem package to a deb package padma: these ruby libraries are already packaged in gem format oh ok.. So are we also going to use that? [23:48] padma: since we want to make all the packages available in a single format ie, deb we are doing the conversion similar to apt-get you can say gem install all of you are in diaspora? nice nope I'm not.
