most companies are not the size or do not see the traffic necessary to have engineers spend time making sure there are no points of failure in the infra when a 5-10 minutes outages with a person restarting a server is going to be fine for most cases. Those that are really nervous, like stores around black friday, can just overstaff or overprovision for a few weeks a year. Chaos engineering when done netflix-style is usually done by purely online businesses that have engineering departments in a good enough shape to want to purposefully cause small outages to prevent larger ones. Most places are not at that stage to begin with.

how do you all feel about providing references when applying for a job? like, i don't mind giving references once i've made contact with the company but i'm not really into shoving people's contact info into a random job portal edit: also all my references have died or moved lol

I’m pretty sure i got this, just so long as i don’t say something racist or crap my pants. i think the commute can be just as (and possibly moreso) taxing as any given actual job, so i’m kinda stoked.

Dongslayer. posted:available upon request Pretty much this. References are such a waste of time though, the candidate is only going to suggest someone who will give them a favourable review. It's also telling when a company asks for references, that is they're probably run by old people who are stuck in the 1970s mindset.

Just got an email from a recruiter talking to me about this amazing new opportunity at a "startup" that is backed by a $5Bn valued major player so it's the best of both worlds! and you get to play with the latest cutting edge tech: "They works with the latest stuff - They do Grails, AngularJS, TypeScript, ES6, npm, node, webpack, Gradle, Sass, Spring and willing to train on it. We are looking for good Java Developers." aren't we all?

Disagreed, freshening yourself up on core techs which you might not have used in a while but will be tested on none the less is important. Unless you just apply for jobs that are a 95% fit for what you're doing currently.

had a really fun talk with some people over in ops for an internal temporary gig, and they repeatedly said ‘yeah we are a new team and we need all the help we can get’ so I guess that bodes well for me ‘why do you like ops?’ ‘you work with everyone and learn a bit about everything and despite it being a crushing workload it’s fulfilling at the end of the day’ ‘is international travel okay?’ ‘I have a fully valid China visa’ ‘oh dang, that’s extremely good’

qhat posted:I don't mind saying a number first, I've got a pretty good handle on what I can get and what I should walk away from. The worst thing is going through an entire interview process and be given an offer that isn't even close to what it would take for you to switch jobs, so I'm happy to screen those clowns out early if possible. unfortunately it's not possible every prospective employer has a number in mind for what they want to pay, but the earlier you get that number from them, the less correct it will be as they spend more time with you, and you get closer to closing the deal, their willingness to pay will often increase, often very considerably. this is also why recruiters will send you out to a job whose advertised pay band is $30-50k less than you are looking for -- they assume the pay will go up after they get their teeth into a candidate the worst problem of course is that you don't know how elastic the pay band really is. until you go through the whole process, you won't find out how much they can "stretch." there's no easy solution

Oh absolutely that's a good. Stuff like "memorize the canonical way to OOP a Sudoku or tic-tac-toe for an interview" isn't the same as "do OOP for something new to both of us" and talk through the process. That's what I mean.

So if people think SQL can't scale horizontally (sharding?) and you gotta do stuff in the  and you need to go NoSQL is this a redflag?

Lots of cloud providers have NoSQL databases as a service that deals with a lot of that for you. It could be that storing documents in a NoSQL db is the right move, and they were just shoehorning it into a sql database because of momentum at the time they made the product and now they see an opportunity to do it right. But probably not, and go with what Sapozhnik said

that's almost an entire sixteenth of a commodity server's ram when you've got a working set that can't fit into a single instance's ram then you start thinking about application level sharding when you're google or facebook or amazon and your business data is a gigantic planet-spanning graph, that's the point at which you bust out the super-heavy weaponry. i mean don't get me wrong it's pretty cool that you can get (something that resembles) the software that runs these sorts of operations for free to play around with and study, but these systems require a highly knowledgeable and focused operations and engineering organization to effectively manage, and that tribal knowledge will remain tribal knowledge and not become easily taught and disseminated simply because very few companies actually work at that level. given the political effects they are causing, there is an argument that very few companies should work at that level, but that is an entirely different conversation. long story short anybody who uses warehouse-scale distributed db systems willingly is an idiot, it's what you use when you're so huge that you have no other choice.

also a disclaimer, i don't actually have much practical experience with this stuff so uhh don't use my shitposting to make career-impacting decisions. still, i don't think it's controversial to state that the tendency of "nosql" databases to turn your operations experience into a living hell is well documented.

Sapozhnik posted:good heavens, an entire terabyte you say? I don't know why but there's a team in my company using some dynamodbs because they think a million records is apparently too much data to query on without nosql. This is the same team whose webpage load time I brought down from 15 seconds to half a second by adding a single index to one of the SQL tables they do have. The funniest thing is they're not even sharding their dynamodbs rofl.

I'm fully convinced that a lot of the people that are using nosql think it's a data store that uses black magic incantations to somehow make sorting over millions of records an order of magnitude faster than just running a query on an index.
