> why should you continue getting money off me and my customers? Welcome to the concept of fair market value. Less snarkily you're conflating the concepts of price and cost; theyre not the same thing and theyre not the same for you

Thats the “what it costs” section? Im a bit impressed if they are down to ~3ms per handshake. When I last looked at TPM signing (many years ago) it was more like single digit transactions per second. That said, even 3ms TPM signatures are g

yes, and you can do it entirely in developer instructions (AGENTS.md/SKILLS.md). No hooks or other executables needed. Check out `codex-subagent-router` for an example. Its overly complicated, and has a few things wrong, but it mostly

Maybe cloudflares workload is substantially different, but i think youre missing just how long that tail was. A “lot”, maybe half, of unique objects werent requested a second time in any meaningful period time. Like days. And edge nodes hav

When I worked on a large CDN the content popularity distribution was heavily skewed. Think 20-40% of throughput from top 1% if content, and 80-90% from the top 10%. Anything outside of that had a very low probability if ever being read ag

NPUs, at least for apple, are built for relatively small scale efficient background processing. Theyre taking care of extracting structured metadata from freetext, recognizing people & text in photos, indexing file contents, etc. they d

There are, internally, and theyre pretty good. I always tried to use the AWS Docs style guide when writing internally, for example. Theyre specific on how to refer to products vs services vs features, which nouns to use, tone, grammar, etc

This is just the era of AWS (and amazon APIs). A lot of them look like SOAPy xml rpc because thats how they started, based on internal service frameworks. Check out SQS or S3 for similar examples. Around 2010-11 there was a shift towards RE

The damage estimate they use will be hypothetical total replacement cost, including multiple employees time, truck use, permits etc. its very trivial for any sort of repair to have a nominal cost in the thousands.

Yeah, vaguely aware that you could diy the entire setup with refrigerant etc. But its not relevant at local prices here in AU. One of the interesting things I noticed here is that manufacturers are providing exchangers and head units that c

Nope, different service. We were introducing new methods using POST and (iirc) some differential pricing based on the actual request params. Which made it a different code path, metering value, price, etc than the existing GET requests.

It was the same old kona files for metering until at least a ‘23-24 when I last did metering/pricing work. “Luckily” the size of the EC2 pricing plan was so stupidly large that it was forcing improvements to how those were serialized,

Thats not really how estimates work. The actual metering data is ingested in near real time. The metering * pricing plan is processed within a few hours; thats what youre seeing for “estimated spend” IIRC. The actual billing accumulation is

by donavanm 2mo ago
Ive dealt with this error at AWS. It’s a unit error. In my case we _meant_ to charge like 5¢/GB, but missed the unit (GB), and then the billing system defaults to bytes. 5¢ per Byte of data transferred meant some customers were seeing

That’s not quite fair. As I recall there were about 1,500 people in that part of the hardware org circa mid 2000s. Before PA Semi there were pretty established teams already doing VLSI/PD/verification/validation, PCB, and of

Youre out of date. The revenue numbers from cloud infrastructure (iaas) are HUGE the past few years. DB licensing etc are mixed in to “ Cloud services & license support” so it is hard to pull out. But youll notice that: - “iaas” (OCI) i

I dont think those points are in conflict? I certainly read it as yet another example of centralization of power and advisors/advisees who are only interested in “yes.” I read the NSC/JSC/cabinet advise as the passive failure

Nice! Awesome coincidence, happy to hear from you. I feel like that team was somehow both the tail end of the system admin hacker era and on the forefront of what would become “devops” and system management infra. And now, cloud… cloud, as
