Often, an instance of a class represents a mathematical entity (vector, matrix, imaginary number, mathematical set, et al) where less than might be a fundamentally reasonable operation, especially in some specific context. His example is us

That tends to degenerate into resetting the password every time, or logging in from the password reset email you sent them. In either case, you've moved security to the user's email program which is (sadly) probably an improvement

Though he says a lot of this is to avoid bulk cracking of your passwords. As with, say, OneLogin, your keychain provides a really easy way to bulk crack all your passwords - steal the key.

Redis Sentinel's semantics are an excellent solution for what I use Redis for. Redis Sentinel's semantics are a terrible solution for things I use relational DBs for. The fact that clustered relational systems accepts transactions

There are systems that get this right. Just apparently none for Postgres or MySQL :-(

Many of those choices to make it easier only work if you're willing to disallow a lot of SQL semantics. Like, tradeoffs in consistency? No transactions? That requires not implementing some important bits of SQL.

Can we just start posting "Jepsen or it didn't happen" on these? Clustered relational DBs are really remarkably hard to get right. A shocking percentage of projects and vendors don't really even make a serious try (cf Ga

Yeah. Makes me very curious where they draw the line. Because it is not obvious from outside.

I'm never sure how to reconcile PG's stance of "our founders are good people" / "X-ray vision for character" with some of the things that some of the portfolio companies do. For instance, the vigorous, lon

The abstract mostly seems to state "increased intelligence is currently too difficult to measure, so we wouldn't know." Which is fair. But "is a myth so far" suggests disproof, not proof that it's not currently

Giving up power makes it easier to write good tools. That's one reason that IDE support for Java is amazing, but IDE support for JavaScript isn't nearly as good - JavaScript allows and encourages way more freeform do-it-however

When there's a compromise between user and developer happiness, remember the developer is usually the one picking. So it's understandable that users often do an end-run around what they choose.

Indeed. HTML and CSS are great examples where by giving up expressiveness for the author, you can gain more power for later reprocessors -- uncommon for programming languages (because halting problem) but a common thing to do for language-l

We're basically there already. Disney pushes back the copyright date every decade or two so that Mickey Mouse (steamboat willy, 1920s) never gets into the public domain.

Not sure which bit you're saying "incorrect" to. But okay. Are you arguing with "the era was famous for indebted Yuppies", then?

I love the point about the Oplog. There are a few equivalents for common SQL DBs (see LinkedIn's Databus for Oracle and MySQL), but in general, getting access to the write log is really hard. Even though it's sitting there! It wou

Yeah, that'd definitely be the Reagan administration you're thinking of. The UK was doing something similar at roughly the same time under Thatcher, or so I've heard. That era was famous for its very-indebted Yuppies (and the

The fact that entrepreneurs are regularly encouraged to drop out, so the investor and professor roles are potentially in conflict?

They frequently use methods where you have to double-click on an email attachment. Most people consider cut-and-paste from a web site to be safer than that. Also, non-TLS web sites can potentially be hijacked in flight, so this could happen

Other than equity, there are a number of choices there. One is working conditions: you have a lot more freedom to grant people unusual working conditions if you answer to nobody. Another is compensation. Not only could you grant more equity

Mike's idealistic. I went to college with him, then worked with him at MetaCreations in Carpinteria. He also got a nicely-ranked Hacker News post for taking apart some SSL chicanery that a hotel was doing on his honeymoon, for instance

Whereas I kinda assume the NSA is already using it, and that's one of the big reasons to care.

McDonalds is very open about investing in real estate. They own all their own locations. The restaurant is basically just to pay the rent on the land they own.

A reminder that one way to keep your job security is to learn an important legacy tech really well. I have high hopes for Ruby on Rails -- it won't have the longevity of COBOL, but it's gonna be a nightmare of a legacy system ;-)

Whether the US gov't is good at it is irrelevant, if we assume somebody else could plausibly be better. But if they're anywhere near an upper bound, then whether they (a well-informed first-world superpower with a huge budget and

Okay. Now do you trust the US Government to decide which ones are their one-off situations?
