02:57.43 rocko blrcad: how to set up the dev environment ?
04:37.25 brlcad rocko: did you see the wiki page on compiling?
04:38.03 brlcad install a subversion client for your operating system, install cmake, download brl-cad from our subversion repository, run cmake on it, then compile
04:38.07 brlcad ~cadsvn
04:38.07 infobot To obtain BRL-CAD from Subversion: svn checkout https://svn.code.sourceforge.net/p/brlcad/code/brlcad/trunk brlcad

06:33.19 brlcad Happy New Year everybody!
06:33.32 caen23 happy new year
06:57.09 Apra_ Yeah same to you brlcad, caen23
09:02.18 Apra_ I was going through homebrew cask github page where I saw many ruby source codes of different files...every other file had sha256 hash written..why are these hashes seen on every file?
09:17.24 *** join/#brlcad ARChak (~vircuser@117.214.43.90)
09:30.46 caen23 Apra_: they verify the hash of the downloaded installer against the hardcoded value, for both security (to make sure they downloaded what was intended) and for robustness (to make sure the file was downloaded and saved correctly)
09:32.30 Apra_ caen23: Can I ask how do you encrypt these...I mean whats the message that you encrypt to get these hashes?
09:34.34 caen23 there is no 'message', it's the bytes in the binary file
09:35.33 caen23 also, you don't encrypt anything, you compute a hash
09:36.20 caen23 encryption would require authorization, but a hash isn't really designed for that
10:48.10 Apra_ ohh

13:20.55 sagarwal I was doing this task: Eliminate 50+ lines of code duplication. I found a duplication in OGV which can also be classified as an error in code. I wanted to ask, can I claim it in Find, reproduce, and report any bug in the Online Geometry Viewer (OGV) Task too?

19:01.14 brlcad Apra_: if you have a mac or linux, you might be able to run the shasum program to compute a sha256 hash
19:01.34 brlcad md5sum or md5 is another similar program that computes a different hash (and md5 hash)

21:52.44 caen23 Apra_: just so you know, you're not really allowed to run macos on non-macos hosts (licensing stuff, i believe). and even so, i don't think the virtualization will be any good
21:52.48 caen23 but have fun trying
21:52.52 *** join/#brlcad ARChak (~vircuser@117.200.91.248)
21:53.03 caen23 oh, and also, i don't think there's anything left to do regarding homebrew casks
21:58.59 Apra_ caen23: I believe archer is not there in the casks(https://github.com/caskroom/homebrew-cask/tree/master/Casks)
22:04.50 Apra_ So just thought of making it up for archer :)
22:07.45 caen23 the cask that's there (brl-cad-mged) is the dmg installer on sourceforge, which does include archer, even if it's not in the name
22:08.13 Apra_ okk
22:08.30 Apra_ bad luck
22:13.00 *** join/#brlcad Caterpillar (~caterpill@unaffiliated/caterpillar)
22:17.59 caen23 although
22:18.08 caen23 i was meaning to add a similar task for windows
22:18.31 caen23 but i didn't think anyone would be interested, i think i'll write it up soon
22:18.36 Apra_ it would be great
22:20.18 Apra_ I would ask you to hurry...coz after 4th Jan I would have some problem...I won't have my laptop after 4th
22:21.08 Apra_ sorry...I sounded a bit rude
22:23.02 *** join/#brlcad ARChak (~vircuser@117.200.91.248)
22:23.45 caen23 no problem
22:23.55 caen23 you'll have to look into chocolatey
22:24.17 caen23 https://chocolatey.org/
22:24.21 caen23 https://chocolatey.org/packages
22:25.19 caen23 try installing a few existing packages with it, then find out how to add a new package
22:25.29 Apra_ ok
22:25.55 caen23 i believe that initially, it won't be from a 'trusted' source, but it shouldn't matter
22:29.18 *** join/#brlcad ARChak (~vircuser@117.200.91.248)
22:37.32 caen23 i wrote up the task, but it won't be available until it's published
22:38.46 Apra_ I will be keen to see it :)
22:44.26 Apra_ I guess the task would be sth like upload brlcad in chocolatey to install it using chocolatey
22:47.58 caen23 yes

23:22.48 Apra_ I found the above helpful to a great extent though :)
