> The notion that changes in interest rates, which generally correlate with inflation, would alter the price of stocks is not obvious to me. Not sure what mechanism you would propose that would cause that to happen.

Higher rates -> reduced accessibility of personal credit -> lower spending -> lower corporate revenue -> higher cost of borrowing -> higher cost of debt service -> lower profits -> stock price

Rates act as a global parameter that impacts performance of companies differently, with the consensus understanding that it impacts debt-fuelled (or what we now usually call growth) companies the most.

You could easily observe this with a cache-cold query performing lots of random IO. EBS latency is on the order of milliseconds, even cheap baremetal nowadays is microseconds

Clearly written by an applicant rather than employer. Your resume is your chance to shine, use the opportunity or pay a service to do it for you.

The reason the author is trapped long enough in meat grinder hiring to notice this "problem" is likely precisely because of some indistinguishable cookie cutter bullet point soup getting them nowhere. If you can capture it in a data structure, it's not a resume!

New comment by stillicidious in "Set up a practically free CDN"

stillicidious — Sun, 16 Jan 2022 02:55:23 +0000

CloudFlare's stock price changes are related to narratives from the past 2 years rapidly fading, like the retail investing world finally learning what a CDN did right at the start of COVID, and expectations of the interest rate environment shifting. AFAIK there has been no material news to justify what's happening to its stock recently, other than many large players rushing to exit extremely crowded trades they all had in common.

There is currently a widespread fear that quantitative tightening could arrive very rapidly, with disastrous effects on high multiplier tech stocks and other debt-fuelled businesses. They've all been getting hammered in uniform since at least December.

I built out my first ISP in 2001, worked in FAANG by 2006, haven't the slightest comprehension of what this is for. Is it some kind of certified partner directory?

Definitely concur. In a well designed language, I'd expect it to be possible to express something a bit closer to C++'s ios but without the crazy verbosity, and without switching mode. It's not that general language features like this aren't possible, it's often that they simply haven't been discovered yet. User-defined literals are a recent concept that helps eliminate some crap in a related area.

Meanwhile, can't complain all that much if zero-cost features can be added to Rust to make it easier to market it to scripting folk. I think that can only be a good thing, even if the feature design is far from ideal.

> Interesting how one might choose to their faith over their life.

The belief in the right to a predictably long life is a new idea barely a few centuries old at most. Not that I'm personally complaining, but the statement did make me think, the value of living longer for everyone is not self-evident (at least from where I am standing), and the presumption that it is seems in itself dogmatic.

Actually, I could suggest a few non-faith approaches to rationalize the benefit of early death

New comment by stillicidious in "UUIDs are popular, but bad for performance (2019)"

stillicidious — Sat, 08 Jan 2022 15:54:39 +0000

That's only part of it, the major problem with classic UUIDs are that writes occur randomly across the entire keyspace. Whether it's represented as a string or in binary, ordering does not change, and so the underlying indexing method must cope with these random orderings at insertion time.

At least btrees perform much worse with random insertions. I don't know how much impact it has on LSM

Someone has pushed a button and it's run the equivalent of cookiecutter on the repo.

Original author could send a DMCA, or they could simply enjoy Christmas and assume a ticket will undo this sometime in January.

Such a number would be difficult to interpret, or entirely meaningless, without understanding the classification methods and policies of each constituent region. This also holds true of overall death statistics.

Finally with local statistics, you still have political dramatics like https://twitter.com/dancohen3000/status/1473480933579923456

Be careful not to confuse average load with peak instantaneous load. Bursty workloads are the bane of capacity planners everywhere.

I'd suggest you are doing far more damage to the reputation of the board by conflating commentary with free marketing. The comment I replied to was the latter. If advertising is permitted where critique from actual paying users is openly punished, what is that saying about the board?

As for the extremely disappointing asshole comment, coming from a moderator is quite frankly astounding. "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith".
