That's one of the main problems. I started with the demo frontend that comes in the box and just hacked on that. I'm no UI developer by any stretch.

Bringing up kythe from scratch is very daunting. First thing I did when I left google, of course, but still really hard.

It sounds a bit like you invented RecordIO[1]. I didn't realize you meant decoding from a stream containing several protobufs. In that case you do indeed need some kind of framing, because there is no end-of-message delimiter. The po

You can't, that's why they said fixed point. Time series data should probably never use floats, for the exact reason that delta-encoding is not effective.
158.
by thedance 7y ago
But the existence of the hex float format, and the fact that it accepts either 0x or 0X, upper or lowercase characters for A-F, dot or comma for the point depending on locale, and either p or P for the exponent, all contribute to the reason

I think the bigger risk is you write a blog about some "cool stuff" you are doing and it's actually not cool, it's dumb and obsolete and people who might have been thinking about working at your company go apply to Micro

Yes, they just published this article that compares two cloud server platforms based on how many times per hour they can run SPEC, which is totally on-brand for them and either a new low in the art of server benchmarking or a wry attempt at

I can't think of a single thing in the C or C++ standard library that is state of the art. Often they are actually quite terrible. Some of them just can't be fixed because of ABI compatibility issues. That's why, just as a

I don't know. I'd be very squicked out to expose a C++ HTTP client to the big bad world, i.e. as a web crawler. For private use, technically speaking gRPC contains an HTTP client. More likely I'd fork a process in a safer l

HN is collectively schizophrenic on this topic. On the one hand, the comments say that nobody really needs anything fancier than JSON. On the other hand, other comments say that if JSON parsing shows up in your profiles, you should switch

It's not silly at all. Replacing a lot of sprintf calls with Grisu and later Ryu made a huge difference in the production fleet at my last job. It wasn't by any means "the bottleneck" but it was costing real money. Mo

FWIW, as a Xoogler, I find I can get pretty far with 1) abseil, 2) grpc, 3) protobuf, and 4) groping around in every open source Google project to find the thing I need (for example, until recently, Cord could be found in random projects bu

There's nothing fundamental about protobuf itself that prevents streaming output. You just have to make a pass over the proto structure first to compute the sizes, then stream it out using the precomputed sizes. At no time do you nece

Well yah, those are all ratio-tuned codecs that are very slow. LZMA beats bzip2 on both ratio and speed so you might as well forget about bzip2 forever. Zstd, snappy, LZ4, or even brotli are probably better choices than zlib for most peopl

Why is it important to have absolute accuracy on the 12V pin?

But how do they control it? Is it just that they make a good product at a market-clearing price, or do they abuse the system somehow? In my mid-sized American city there are not just one but two local mattress makers that I could buy from

There are plans that are exempt from ACA's "requirements" because of course there are, and the current administration has used its rules-making powers to expand such exemptions. These are not limited to backwater states with

That's true but it's also true that the plans need not cover maternity. There are tons of ACA plans that don't. And in "markets" with one player they can just name their price. None of this is your fault of cours

Another good example of long-term decline is gold. In real dollars gold has never returned to its 1980 price. It went up 10x in the decade to 1980 and some people thought it would just go up forever. If you bought the dip after gold peak

This advice is both common and crazy. Each individual does not live the average life. Being able to recognize once-in-a-lifetime events, and act on them, is a rational strategy, even if it seems like it is not the optimal strategy for the

The market has just been unhinged lately, because there are a lot of huge positions that would love to sell but just can't unwind. Consequently there has not been an effective downward pressure on asset prices, and a lot of garbage is

As someone who has had to shop for health insurance before, how am I supposed to just "buy any insurance I want"? On the private market? That doesn't work for a lot of people. For example, a person who is already pregnant wil

The security of the BlackBerry came from the fact that an organization could deploy their own data message servers, the “BES” that’s connected directly to your intranet. It was a bit vpn-like, but at the application layer. IT guys liked it
