I love hearing these kinds of stories just to remind myself how not dysfunctional my own company actually is.

Version number hangups are indeed a problem, I don’t mean to suggest my organization has escaped them. But if you can wade through those successfully, the technical solution itself often does make sense.

Is this a problem inside a small company though? I would expect there to be much better signals about how alpha-ish a library is in that setting (i.e. talking to your coworkers).

Yep! I think it's fair to needle open source software, but it absolutely makes sense for a lot of internal development to adopt this sort of versioning policy.

This is a good point, arguably even fixing any bug breaks compatibility, at least if you're a kernel maintainer. An (in)famous Linus quote: If a change results in user programs breaking, it's a bug in the kernel. We nev

This is a comment on an article about Go package management, which enforces that packages a versioned with a semver-esque string.

What do you mean by the 2nd time? Did you rewrite the whole thing again some amount of time later?

At a high level this comment is correct, but SWIFT is not a settlement network. A message on the network does not actually represent the movement of money between accounts.

Yes, everything meaningful in society is trust based. I really hope crypto maximalists have made it this deep into the thread.

I have been learning (via books, podcasts, coursera, etc.) about what money is and how it’s created, both domestically and internationally, both in commercial banks and central banks; and let me just say this is a superb summary of all o

When the cost of selling to such a niche group outweighs the revenue, that’s the premise of this thread.

Can you provide a source of the “inferior personality” narrative? I have heard about how interviews/character essays/etc. can affect admissions, but that’s a pretty lofty accusation.

I've given ~50 system design interviews. Personally, I'm looking for a combination of problem solving and collaboration skills. I am not particularly concerned about the quality of the system they have designed by the end of the

Where would I find data about “toxic assets” from the crisis and how they actually fared? I’m very curious about the details.

Can you be precise about what they knew? Knowing a crash is coming isn’t necessarily that interesting - a crash is always coming, it’s just not clear on what time horizon, or what its secondary effects will be. JumpCrisscross did make the

Not commenting on work habits or company expectations, but I found “companies don’t reward morality” a funny statement: I would argue that morality is almost by definition something that doesn’t get rewarded. One is moral simply because the

I'd suggest that most of society still runs on the honor system (especially finance and law), it's just more abstracted away from interpersonal relationships than it used to be. The existence of things like encryption often decei

I’m confused about what the point is here. Isn’t every single one of these companies venture capital funded?

One thing that gives me hope is that the actual language designers have the right view on it, and I think are guiding the community in the right direction without explicitly condemning the way a lot of things are currently done (which would

Java’s verbosity/abstraction problem is unfortunately not due to the language or libraries at this point as much as it is the programmers - the hardest thing to change. You need only to look around this thread to see Java programmers w

By application state, do you mean something like an in memory cache? I would prefer having no such state in the first place, and have all meaningful state in the DB to be pulled out or mutated as needed. I recognize that what you’re advocat

What do you consider naive? JDBC supports transactions, I’ve had success with that.

Do you seriously allow users to configure which logging framework is used through a UI? Perhaps I’m misunderstanding what you’re saying.

by pgwhalen 5y ago
This is all considerably more abstraction than I have wanted or needed when writing Java. When handling transactions, I’ve passed around the same connection before committing.

Consider this scenario: current AML practices catch 1% of laundered money, but deter additional money laundering 100x. In effect, this means nearly all money laundering is stopped because of these practices. That seems extreme to me, but it

It's worth pointing out that the Secondary Market Corporate Credit Facility has ended, and the Fed has sold everything it has bought [0]. But of course the precedent has been set, which may be why you chose to use the present tense. [0
