watching developers try to efficiently implement joins and transactions at the application level on top of mongo because their leadership got caught up in the nosql hype is fun to watch

its the nesting that kills me. like yeah no joins sucks but it doesnt add that much cognitive overhead if you just accept the poo poo performance. its the nesting that kills me. change a document? hope you remembered to update that document everywhere its been nested! good luck! no transactions is balls though

Fiedler posted:great, you've figured out that you want to write developer tools. now immediately go apply for those jobs. worst case is you're not hired and you try again in 6 months. yeah there's a fair amount of these jobs out there. just look up some tools that you've used or thought about using and see if they have a careers page. if they do, apply for one that looks interesting. if you don't get an interview, re-apply in 3 months. if you interview but don't get the job, reapply in 6 months

IMHO you should spend your year looking for a good job that you would want, not studying (I mean, unless thats what you want to do). you seem p smart and competent and just need to shoot the job-getting odds, not get more booksmart

if u literally think its a binary good/bad use/don't use choice between nosql and mysql/postgres you clearly aren't doing anything serious both things have applications "lets use mysql for a distributed cache!" and "lets put our data model truth store in mongo!" are both dumbass ideas

it's a lock-free (well maybe wait-free) concurrent b-tree, it's pretty neat

Rust hacking suggestion: take your functor thingy and profile the compiler and see if you can figure out why the slow part is slow, and what to do to fix it

tool and library development is my favorite part about my job since I dont have to be nice to the customers at all. at this point most of my job is pointing people in the right direction or gesticulating wildly in front of a whiteboard about an algorithm or process. then whenever we run into a problem that doesnt have a fix off the shelf (deployment tools, source code generators, etc) I get to throw my headphones on and just knock out a bunch of code, and is probably the only time where the requirements are actually 100% known at start

Star War Sex Parrot posted:oh right they got that in the wiredtiger acquisition yeah, tbh it started out no more reliable than the filesystem, which, eh, isn't so bad people resent it because it represents the truth that good engineering is useless without good docs, support, or onboarding, and mongodb only did the latter at first, and started acquiring the former recentlyhonestly, any database under a decade old won't be reliable. then again what about basho and riak, that well engineered software that had more conference attendees than users. the thing that gets me is the people who smarmed about a 'real' database, when none of them know what isolation level transactions run at, dump poo poo into persistent message queues 'to handle failure', and then slap a dht'd memcache atop and do stale reads. it's fine, i mean i'm not saying mongodb is good but frankly you can build a lossy system out of everything and everyone already has. the people making GBS threads on mongo are the sort of people who then go and use etc, consul, and a variety of home brew key value stores backed by mmap , complete with a homebrew replication system that's baked atop raft as it tuns out raft is designed for teaching, not performance. poo poo on mongo for all i care, it has a crappy name, poor transactional support, and well, god i tried to do a join once and it was awful but like, you do realise 'good and smart' engineers have repeatedly tried and failed to build something better in that market space
