That took my comment to a much darker place than I anticipated—I think basic marketing is ok, and even if you’re passionate about design, you still should be thinking about the business’s bottom line. But, like, https://teenage.e

Teenage Engineering seems to run partly on hype and halo effect. It makes cool things you can’t afford, and you buy something cheaper. Selling a vinyl cutting machine keeps them in the news, which keeps them in your mind, and then you think

My experience is that there’s a percentage of developers who get it right and intuitively understand the serializable isolation level. And database performance is a crapshoot. By “crapshoot”, I mean you mix some developers, data, and databa

The reason why so many programs could be allocated upfront is because if they couldn’t, maybe we just didn’t write the program.

I’m leaving JSONv2 enabled and writing my JSON code to use that API directly. From what I understand, it’s not default because there are performance regressions in some edge cases. But the typical performance is much better and the API is a

When I’ve visited the big data centers, they had gates and security relatively far out from the buildings. How would you get close enough? It’s not like the World Trade Center in 1993 where you can just drive up next to the building. (It’s

Ah, I can see what you’re getting at. There is actually a system which is a better fit for me, which is the Mac. I can still run the software I want on it, and even though the security model isn’t tight enough, it’s improving. Linux is also

The 0.5 comes from debiasing the round-trip. If your conversion from high precision -> 8-bit is just multiplication by 256 and then truncation, then you’ve got the mid-riser quantizer. The +0.5 comes from interpreting a value of 0 as buc

Honestly, I think the permissions model for desktop and laptop computers is way too permissive to begin with, I think it just kinda sucks and doesn’t do its job. Apple is kind of fixing it but there is a long way to go. There have been alar

This particular permission is pernicious, ponder for a picosecond the possibilities: It’s used for writing keyloggers. That’s it. It’s the permission that lets you write a keylogger. It SHOULD NOT be just a click away. It should require som

> Why not scale to fill the available bins, though? i.e. trunc(result * 255.999)? That’s half of the mid-riser staircase quantizer discussed in the article. (The other half is coming up with the reverse.) (I would implement it as min(flo

Addition in this case is cutting from 2^64 to 2^33-1. The 2^64 number is the number of inputs. For an operation which is commutative, you expect the outputs to be 2^63+2^32 or smaller, since you’ve introduced symmetry.

Sure, but I wasn’t thinking of the brokerage fees. Things like the spread.

It’s achievable. It’s called “direct indexing”, and there are some extra costs associated with it, so for most investors, I think it is cheaper to get QQQ. You can flip that around with tax loss harvesting but I don’t understand that strate

I realize I might have been mixing up QQQ with ultra pro QQQ… anyway, yeah, you can replicate QQQ. I was thinking of Ultra Pro QQQ.

Real question, where are you going to buy the swap agreements?

by klodolph 4mo ago
QQQ gets the leverage from, among other things, swap agreements and futures. I don’t think what you have could be reasonably considered “pseudo-QQQ”. It’s like copying a cake recipe, but leaving out the flour and eggs because they are too e

That definition of durable doesn’t seem useful to me, sorry. I want the failure rates and scenarios.

I like to think that the true AFR for data is bounded by something like 10^-3, because maybe that’s close to the rate at which civilizations collapse. You have to use a kind of subtle definition to support 10^-7 or 10^-9 or 10^-11. Or maybe

The half-remembered storage system I pulled those numbers from had records ~100G in size, so a 10^-7 loss is 1 loss event per year, per exabyte of data. A loss event is just “at least one bit in the record cannot be read within a certain de

I don’t have any respect for the viewpoint that “durable” is equatable with “stored on disk”, and I don’t want to spend time accommodating that viewpoint. It is just an oversimplification in a very bad way. AFRs and discussions about differ
