I would focus on one of the big view players - React or Angular, from facebook and google. It seems like the old school jquery dom updates is out of fashion now. I wouldn't worry about the toolset, it sucks - webpack I guess has some uses.

I would focus on the core thing, e.g. React and javascript fundamentals. Tooling and stuff will follow along once you get a job in it.

I'm interested in using nodejs to replace bash scripting, I loathe doing any kind of logic in bash and I just want to excise it. No maven or gradle for build tools. I'll revisit later.

Good domain name as well, easy to memorize, good job.

to pick at the 1-2% numbers a bit the impact of IQ depends on the individual; physical size/height is only profoundly important for the success of certain people - athletes primarily. however, both also have correlation with success. I'm sure the paper was more careful than this article.

IQ is often used as a proxy for intelligence, when in fact it's just a set of standard metrics that nobody thinks is that good beyond a certain point - after all the term comes from early attempts to quantify developmental delay. Leaving that aside for a moment.

I thought you meant losing cycles due to blocking or spinlocks when you said strangling.

>Locks et al. are low level interface

Actually no, this is the world of multiple cores. Threads are the most trivially accessible way to parallelize activities, so they are just a modern primitive.

>Once you go into clusters, you loose your precious notion of shared memory anyway

Zookeeper. Distributed clocks and sequences and all that often require a few bits.

I was just making fun in the last sentence, if you didn't catch the linguistic joke about populism in my word choice. I'd guess you work in erlang.

1 Java does get concurrency right and the trade-off made in going to a single threaded nodejs process will appear (as I have bitterly learned) as performance becomes important. Keeping a sanitary event loop (think about large uploads, downloads) turns out to also be a difficult problem and one with less tooling and experience.

2. Allocate Direct can be used to get off heap memory, I don't recommend doing this, but if you really need to worry about your GC pauses, then it is very possible to use java without it and I have seen that done.

I do agree that keeping skill levels up across a long career is difficult. Maybe these memes come up because it's a convenient excuse not to put the effort in? It's very easy to get complacent if you are smart, get things done and have a comfortable home life. We have to train to get that brass ring, to stretch the analogy ;)

There are existing tests available to test for being a sociopath...

this is super dehumanizing.

how about, do the work sample test and a few phone calls with somebody smart. You're going to scare off a lot of very picky people if you seem like you're going to be an irritating test focused person - yes lots of us do well on tests, I really don't want to talk about it every day.
