spring comes with a ton of poo poo, it's true. but anything you want to do with it is very easy to accomplish & has like 3 baeldung guides on how to do it

I mean I agree that coming into a project with more lines of xml than java can be weird at first, but you get used to it after a while

im supposed to be teaching a bunch of colleageus about Python / backend programming in a single 2 hour class as part of our "internal training" (lol) they have (mostly) very little tech knowledge (altho there's a couple of JS devs in there) currently im thinking like 1 hour running over the basics (whats programming, whats backend, vague stuff about our company's tech stack/arch) and then like 1h of code academy but i have the feeling that this will be ultimately inconsequential other than just a "hey this seems cool", and wont lead to any deeper knowledge (kinda inevitable given 2h) u guys got any good tips 4 me?

I laughed when I thought of "dehumanize yourself and face to bikeshed" and did a Google search to see how many other people thought of it before me. There's one hit and it's from two years ago in this very thread:eschaton posted:dehumanize yourself and face to bikeshed But wait! What about the inferior British spelling? Convoolio posted:dehumanise yourself and face to bikeshed The PL thread beats this thread by a year! But still, pretty good that the only two Google hits for the phrase are YOSPOSts!

fun fact: -ise is not the british spelling, this is a common misconception; it depends on the styleguide you're following. for example the OED reccomends -ize. i personally as a british person also prefer -ize

(obviously you can't make people give craps about things, but imo it helps to at least consider the question) my final advice would be: try to make it fun, or at least mildly interesting. an example here would be one of the CS professors at my college, and the activity he would do during the first class period when he taught the networking course. this class was one of the lower level classes in the department, and it was a requirement for CS, MIS, and maybe was an elective for other things, so you had a mix of people from "i am totally already dedicated to being a cs major" to "i'm not sure yet" and "i have to take this nerd class omg". the activity he did was to give every student a sheet of paper that was folded in half. then he would explain that on the inside of the paper there was a set of instructions, and when he said "go" you were to unfold the paper and follow them. then he says "go" and you unfold the paper, and it says "you are number X. everyone else has a number, too. you have a list of instructions below that you need to follow". and the instructions were like "give the message 'hello' to number Y" or "if you get the message 'the job is done' from number Z, give the message 'continue' to number A". what happens of course is that the room at first explodes into people yelling, but then usually what happens is that everyone organizes themselves into some system of message passing. then when the class is done, the professor would put on his aviator shades and say "imagine four computer science students on the edge of their seats..."

cinci zoo sniper posted:how's the structure suited for ad hoc analytics by people used to generic row databases? do you like mapreduce? because you should probably like mapreduce (or spark, or anything similar) like lets take hbase as an example: its basically a giant disk-persisted multi-dimensional hashmap; you have keys that serve to link information in columns together pretty much, and column families that serve as top level organization for the types of information you might be storing, and then qualifiers that zero in on the actual data, so if you transformed this information into a row, it would look something like <id> <column_family_1>:<qualifier_1_1> [data] <column_family_1>:<qualifier_1_2> [data] <column_family_2>:<qualifier_2_1> [data] etc etc now when it comes to queries: its pretty much key-value mechanics as you would imagine with a format that is basically a hashmap; you can do scans and tricks with partial key matching to get a collection of data, but thats about it there are filters that you can apply to your queries but those are applied to the columns so it can be kind of weird because it feels like you'll get partial results back because one column with the key you're looking at fits the criteria but another one doesn't so it doesn't get returned

meatpotato posted:cmake does seem to work magic but I wish there were better guides / tutorials on how to actually use it effectively for all but the most basic projects. you can pretty much do what you want, just whatever you do, don't try to add files by wildcard, explicitly add them to libs/modules/whatever. then if you need to detect functionality for a framework, write a cmake function and drop it in some directory by itself.

quick update on emulator: in swift, switch/case does not have automatic fallthrough. in the metal shading language, switch/case DOES have automatic fallthrough. this explains the last 2 hours of my life.
