Excellent observation, and this is the entire problem. They pledge their unrealized capital gains as collateral for billions in loans, spend the cash, and pay single-digit interest instead of income tax. Repeat until they die, then their he

> Myth No. 1: The rich don’t pay their fair share > The top 1% of earners take in 22% of total income and pay 40% of all federal income taxes. How misleading. Income here means AGI, i.e. taxable income as defined by the IRS. That excl

It’s not really a game when one player gets to decide the outcome. In poker, the guy who went all in can’t peek at your cards and swap out his hand at the last second.

Compilers already optimize division of a 32 bit integer x by a constant d like: c = 2^a / d so: d = 2^a / c so: x / d = (x * c) / 2^a And /2^a is equivalent to >>a, so we have: x / d = (x *

The low latency matching engines in colos run Linux these days, and we use microwave instead of fiber. Incoming orders are processed by hardware receive timestamp, so predicting jitter doesn’t give you an advantage. Clearing and settlement

Wistful nostalgia about the golden age of HN from an account created 11 months ago. Bonus mention of a pg essay which the commenter clearly only read the title of.

I can google, thanks. My point is that nobody is buying mainframes with redundant memory to avoid refresh stalls. It’s a mostly irrelevant freebie on hardware you bought for fault tolerance.

by foltik 6mo ago
Mirroring is more of a reliability feature though, no? From my understanding it’s like RAID where you keep multiple copies plus parity so uncorrectable errors aren’t catastrophic. Makes sense for mainframes which need to survive hardware fa

In this case it’s better to asynchronously bring the data into the cache, which you can do with a prefetch shortly before the read.

by foltik 6mo ago
Yeah exactly, and it’s absolutely dwarfed by the tail latency of going to DRAM in the first place. A cache miss is a 100x tail event vs. an L1 hit. The refresh stall is a further 5x on top of that, which barely registers if you’re already e

by foltik 6mo ago
There’s no point racing DRAM reads explicitly. Refreshes are infrequent and the penalty is like 5x on an already fast operation, 1% of the time. What’s better is to “race” against cache, which is 100x faster than DRAM. CPUs already of do th

Love the format, and super cool to see a benchmark that so clearly shows DRAM refresh stalls, especially avoiding them via reverse engineering the channel layout! Ran it on my 9950X3D machine with dual-channel DDR5 and saw clear spikes from

Based on the recent leaks, their system prompt explicitly nudges the model not to do anything outside of what was asked. That could very well explain why it’s not fixing preexisting broken tests. “Don't add features, refactor code, or

So... a vibe slop index to keep track of all the vibe slop apps? The cherry on top: it’s completely broken! Enable the Context Awareness filter, the list shrinks. Now enable the Auto-pasting filter, the list grows back.

The moon isn’t a known quantity, we sent a handful of people there for a combined few days half a century ago. There’s immense scientific and engineering value in keeping a generation of engineers fluent in deep space operations. If you’re

The distinction is kind of meaningless, advancing our engineering capabilities in space is advancing the science. And as I said, agreed on the concerns about cost and sending humans.

Fair point, but that’s an argument about prioritization within NASA’s budget (and its size relative to other spending), not the scientific value of the mission.

Do you really disagree that it’s advancing science? Surely actually testing hardware, building knowledge on how to run this type of mission, learning to use lunar resources, figuring out how to keep people alive, etc. will teach us things w

Apparently there’s no economic pressure toward brevity in LLM generated slop comments either. And no, they’re not flat subscriptions. Use more tokens and your quota is gone faster.
