jony neuemonic posted:i've seen tickets sit in code review for three weeks. no longer at that company, thankfully. I had a 3-line code review take four months in 2014 because I was changing this fundamental configuration file for one of our products and not a goddamn person at the company seemed to understand the full set of implications. Part of the delay was also because I had to write a separate project to backfill the data that the config change was causing. It was p neat.

we have three big software releases scheduled for one of our products. release 1, 2, and 3. they go in order, and each release builds on the previous one. except management keeps delaying release #1 because they dont want to accept a couple bugs that dont really matter and we should just accept for now, but they're also unwilling to budge on the scheduled release date for #3, so as of today our official schedule has us working on #2 and #3 in parallel, despite #2 being a dependency of #3. cool.

Now, I never really tested that code since it was also just dumb toy code, and apparently ErIog-3months thought it would be a great idea to reverse the endianness of a hexstring by calling reverse on it. i found this recently, you might find it helpful: https://github.com/ssloy/tinyrenderer

CommunistPancake posted:i found this recently, you might find it helpful: https://github.com/ssloy/tinyrenderer Lol, what do you think the screenshot I posted was supposed to look like? edit: My triangle and line drawing code is a nightmare, but it allowed me to pull z-buffer information really easily. Results look way better than the really ought to.  I highly recommend the above short tutorial as a way to learn about the key concepts behind 3D graphics.

haha thanks it's ugly as hell though  we improved over the years and eventually had nice subpixel accurate rendering and bilinear filtering etc, but by that point it was too late since everyone was doing (snort) accelerated 3das a reference, this came out around the same time as our demo: https://www.youtube.com/watch?v=lfqMQG8pws8 it is infinitely more gorgeous

pointsofdata posted:why would you do that? is there some magical optimisation it lets you do? i have no idea, i am not an architecture person. that was just the order the bits were expected to be in when passed to instructions. it was like some weird MIPS variant or something. I just wrote a helper function to deal with the bit twiddling and forgot about it.

Tell us more! it was basically whatever you get when you wire up a sd card for the 4-bit mode with the bits backwards. works out to like 4567 0123 or something idiotic like that. the employee responsible wasted around half a year on what should've been a 3-4 week project, overrunning the budget and pissing off the sponsor he still works here, four years later

need a recommendation. working on a personal project in c#. it involves managing files in directories configured by the user. basically it's just a metadata manager for files on your system. it's not really a problem that desperately needs solving but just something im doing for the hell of it. i have a relational structure in mind that involves 3ish tables, but ive never had to work with sql + c# before so i dont know what the best solution out there is. just sqlite plus some kind of orm? i'd pretty much need a table of hashes of files->path to file, a table of hashes of files->keys, and directories->hashes of files contained. that should let me assemble the needed information into any of the various in-memory structures i'd want for working in directories, listing files by metadata, etc.

never used ef before, so forgive me if this is a dumb question, but the big thing is that i'll want to query this data in a few different ways to list files by various pieces of the data (by directory, by metadata, alphabetically, etc). does ef allow that level of flexibility?
