It's the same with financial content.

I follow N YouTubers who produce genuinely useful and insightful videos on the state of the market and personal finance etc, but the algorithm just recommends people with stock tips and scaremongering junk

I replaced the keyboard in my 5 year old Dell laptop without difficulty. The battery as well (at the same time). It was an instant way to make it run and feel like new

Just going over the PCI bus to the NIC costs you 500-600ns with a kernel bypass stack.

It does not. If this was the case, round trip wire to wire latency below 1.0-1.2 microseconds in software would’ve been impossible. But it clearly is possible - see benchmarks by Solarflare, Exablaze, and others.

You mean like this one directly from AMD showing a median 1/2 RTT ef_vi latency of 590ns (for UDP)?

Using their latency generation card that came out just a few months ago?

Hardware TCP offloads usually deal with the happy fast path - no gaps or out of order inbound packets - and fallback to software when shit gets messy.

Widely used in low latency fields like trading

I'd take the cash. I walk past a half dozen cash machines on any given workday where I can deposit the cash in to my bank account and it'll clear and be ready to spend instantaneously.

I would never accept payment from anybody in gift cards even if I frequented the store. I would assume it's a scam.

On the other hand, it's trivially true that the store which "issues" (caveat explained in the article, they don't actually issue anything themselves) a gift card will accept it as a valid form of payment.

Not 100% safe, even then https://appleinsider.com/articles/25/12/13/locked-out-how-a-...

It sounds like the way the parent front is phrased fits that. If they're only willing to pay in gift cards, that's a requirement, so it's likely a scam. If they're also willing to pay in cash, then you can probably just take the cash and be fine?

Dimson, Marsh and Staunton have been compiling the most comprehensive analysis of historical returns across all major asset classes for many years.

From the summary:

US real returns (1900-2024):

Stocks: 6.6%/yr annualized, Bonds: 1.6%/yr, Bills: 0.5%/yr

But it is noted:

> The 21st century is now 25 years old. Measured since the start of 2000, stock returns have been lower than over the 20th century, though global equity investors still enjoyed an annualized real return of 3.5% and an equity risk premium relative to bills of 4.3%

For US large cap stocks only.

Optimising hardware to run existing software is how you sell your hardware.

The amount of performance you can extract from a modern CPU if you really start optimising cache access patterns is astounding

High performance networking is another area like this. High performance NICs still go to great lengths to provide a BSD socket experience to devs. You can still get 80-90% of the performance advantages of kernel bypass without abandoning that model.

I think this was one, and I want to emphasise this, of the main points behind Odin programming language.

Most people implement them now in my field using mmap tricks so the CPU can do the wraparound for you in virtual memory.

Makes the code trivial

Not only that, but you can also always form a normal (ptr, size) slice reference to any piece of the ring buffer, even when it wraps. This is really helpful for Eigen arrays that you need to rotate.
