"can just as easily use a bunch of relational servers to partition a table" is not true at all. Managing, maintaining and tuning a sharded relational cluster is an astonishing amount of operations work. partition management, re-p

interesting, i have the opposite experience. When we got to high throughput in a cluster we had all sorts of crashes, partitions, and nasty failure modes that required stressful delicate rebuilds. It has similar challenges to a clustered M-

no not at all, you just got lucky. ~5hr security waits are common at the moment (departing Schiphol, happened to a few different friends recently). 3 airlines have moved away from the airport entirely: https://simpleflying.com&#x

Sourcegraph does a decent job of this with their “batch changes” feature

sorry i should have been crisper in my language - there is the new AR async queries (which as you correctly said is a totally different thing). And then there is separately fibered support in activerecord, which will allow the use of the as

i think this announcement https://brunosutic.com/blog/async-ruby & the associated async libraries ( https://github.com/socketry/async ) do a much better job of showing off the potential for the

Exactly, people aren’t always stupid, they’re desperate. Investing in index funds at ~6% average return (or thereabouts) does nothing meaningful for people who are priced out by the 10-15% y/y gains on housing, or are living paycheck t

Devils advocate a little, it’s easy for faang to lead with salary because they know (and we know) they can afford to outpay everyone else. I think obviously all should include ranges, but there’s a reason mega tech is leading the change he

Solo devs maybe. Merging and branching are so much worse in svn that it’s not good enough for “most developers”, aka those working on professional projects with a team of developers. Sure we used to make do with svn, but I have no desire to

Yeah absolutely. Dropper posts are a total game changer, don’t know how you could think they’re gimmicky

Why wouldn’t twirp satisfy your needs? It’s just protos, codegen and http. And supported very well in ruby
882.
by dalyons 4y ago
twirp is great. You get all the benefits of a schema'd/proto'd wire format (like automatic client library generation), but using standard http infrastructure (web servers, loadbalancers, etc etc) without the custom grpc routi

That’s just not true as a categorical statement. Performance aside redis has all sorts of interesting data types, operations and primitives that pg doesn’t that you might want to leverage. It fulfills a different role

Win win for everyone except the banks, they make huge amounts of money off punitive overdraft and are not interested in letting that go. $12.4 billion in overdraft fees in 2020

by dalyons 4y ago
Exactly. Most banks lose money on servicing a standard checking account with debit card for people with no cash flow issues. They make it back in fees(mostly overdraft) off those who struggle - it’s a direct subsidy of the better off by pre

Rule of thumb for “fully loaded” employee cost(inc benefits etc) is 2x salary. So double the cost side :) As you say, engineering staff costs outweighs app server costs by so many multiples it’s crazy. Now modern data eng/warehouse sta

no worries at all. Even though as you said it's "not capturing what people are actually paying" it's related, and still horrifying to me, as a measure of overall housing affordability. Esp when you look at places like v

I should have provided these in my first comment: Median-income-to-house price by state : https://constructioncoverage.com/research/cities-with-highes... As you can see California is at a whopping 8.9x US overall: htt

by dalyons 4y ago
What 1980s fantasy is this 3x rule? Median household incomes to home price ratios have risen to ~8x across the US as a whole , not just crazy house price areas like SF/NYC. Canada and Australia are far worse again, pushing 15x in some

thats sometimes true, not always. but a good observation. Even if it is true, having that 90% usecase behind its own service often allows a lot more flexibility to scale for that particular storage problem , and not have to use it generical

I work for a different fintech and both of your points are spot on. Much higher baseline fraud attempts due to online/remote accounts, but much more sophisticated real-time ML/detection systems.

yes, but also its that a lot of the data these days ends up in pseudo-append-only stores (like s3/glacier, or many data warehouse products) where deletes/updates to old data are extremely expensive. Or just having to scan petabyte

For me it’s the opposite… aws outages are much less stressful than my own because I know there’s nothing I/we can do about it, they have smart people working on it, and it will be fixed when it’s fixed

Not “used to be” unfortunately. American banks took in somewhere between $9-15 billion (depending on source) in overdraft fees in 2020. It’s super gross.
