Making computers find bugs so that I don't have to -- mostly in databases, but prior to that in security.

Former: GOOG, MSFT.

Opinions are all me.
(Sure, there’s ways to make sure you aren’t in this situation at runtime, so I wound up doing that to track down reuse in the AST… but now I have to add that test so nobody breaks this assumption that could be in the type system. Or I could rewrite the whole AST library and force immutability...)

But thats… not exactly how objects in python work. And this makes adding AST modifications to existing code a little fraught.

I have literally been wishing python had unique_ptr this week because it’s easy to have multiple references to an object and wind up with it getting reused somewhere….

Which is fine in theory, if it’s immutable.

Yeah, this is absolutely something I could have gotten into at that age, especially if my friends were all doing it. I even tried the stupid multiphase sleep optimization nonsense in college for a bit.

TBH I feel like I dodged a lot of bad decisions by going to Seattle instead of the Bay Area…

(I’m a databases person though, and used to work on Spanner, so I’m gonna be biased :P )

Tbh I might be biased, but I think Spanner is possibly more impressive with what it achieves.

Not that S3 isn’t awesome, just that “serializable transactions at scale” is something else.

On the festival front, for example:

Sanja Matsuri is fun, but big/touristy.

But the Azabu-juban Noryo Matsuri was a neighborhood festival that was fun to attend (if very hot in August).

Other local or specific events are similarly fun, but I feel like you gotta feel out what’s happening that week

It was also just cool.

I’ve got a bunch of bar recs for Tokyo since I spent two weeks there in Aug/Sept, but like, no idea if that’s your thing and listing them out would be a lot of replies.

More on the touristy end of the spectrum, but Immersive Fort Tokyo was fun and a lot like Sleep No More lite.

Gotta be comfortable with Japanese or not understanding anything said—it felt touristy, but w/non-speakers as an afterthought.

Well, and if you drink, for the bar thing. Works with some restaurants, too, esp smaller ones.

You do need to know at least some conversational Japanese to really make it work most places, though.

I’ve really enjoyed finding a festival or weekend event and going to that — they tend to be much less touristy and as long as you’re comfortable navigating crowds, a lot of fun.

Another nice thing is getting to know a local bar or two near where you’re staying, if you know some Japanese.

Posting French philosophy at you (friendly) vs posting French philosophy at you (threatening) seems to depend heavily on what part of the last 200 years you decide to pick :P

I think the point was that many dealerships that do sales and loans have incentives to push you to take a loan (over a cash purchase). Which has little to do with if selling cars is a good career (except that, idk, maybe you feel sorry for them and take a loan?).
