mcmoor··on Summary of the Amazon DynamoDB Service Disruption in US-East-1 Region
Also, I don't know if I missed it, but they don't establish anything to prevent outage if there's unusually high delay again?
mcmoor··on Criticisms of “The Body Keeps the Score”
> wasn't actually a scam or actively harmful

I mean people would even try those with enough distress. And to be fair a lot of surprising innovation comes from people trying those! But of course mostly they're a scam or actively harmful.

mcmoor··on Public trust demands open-source voting systems
In addition, and I think the punch line, if you take measures to decentralize and audit every single part of the digital process, you have just made the most expensive pencil and it'll not perform that much better against manual voting to begin with.
mcmoor··on Code from MIT's 1986 SICP video lectures
I guess it's been progressing from being math, to natural science, to social science
mcmoor··on Doing well in your courses: Andrej's advice for success (2013)
And this is why someone made a ruleset for detective novels, so they can actually become brain-teaser https://www.writingclasses.com/toolbox/tips-masters/ronald-k...
mcmoor··on Andrej Karpathy – It will take a decade to work through the issues with agents
Continuous learning seems like one of real criteria of AGI
mcmoor··on The working-class hero of Bletchley Park you didn't see in the movies
I thought ENIAC and Turing aren't really connected and independent to each other? And then again for development of physical computer, seems like Neumann have more claim to him because of his architecture.
mcmoor··on Video game union workers rally against $55B private acquisition of EA
The fools are the people who loans you that money, and they deserve to be fleeced. Unless they actually get back their money, which by this point means you're running a professional liquidation service. It's regrettable that the original owner agreed to liquidate their company, but it's their right and there's nothing wrong with that.
mcmoor··on New Alzheimer's Treatment Clears Plaques from Brains of Mice Within Hours
I've read this article before, and it makes me think OP article, even if working on humans, would still not alleviate Alzheimer.
mcmoor··on NanoChat – The best ChatGPT that $100 can buy
I still miss my days of programming Visual Basic 6. Nothing since then ever compares.
mcmoor··on There is a huge pool of exceptional junior engineers
> right click paste

I am sometimes forced to do this because with markdown, Ctrl+Shift+V will render the markdown instead. I almost never use Ctrl+V because it will append paste instead of replace paste.

mcmoor··on How has mathematics gotten so abstract?
It isn't, that's why it's in own section in STEM, and rightfully so. It's a higher tool that without it, science would come to a screeching halt.
mcmoor··on Bring true randomness to Spotify with Fisher-Yates shuffle
This is always brought up whenever Spotify shuffle is mentioned, but current Spotify shuffle is much worse than this. For me it consistently only plays a handful of songs in my dozens of songs playlist and all others are always shoved way behind in the queue.

My prime conjecture now is that there's some kind of caching reason where it's more advantageous for their CDN if those handful of songs are the only ones that're played. Funnily this also happens in my offline playlist, but I guess this is just because the same algorithm is also used there.

mcmoor··on In Maine, prisoners are thriving in remote jobs
Yeah the conclusion from here [1] is that the biggest reason a prison can reduce crime is not because of rehabilitation or deterrence (even in places that try to do either) but because of incapacitation. It holds people in their prime age of doing crime (15-30) and spits them back out when they're too old to do those anymore. The obvious conclusion is that exile will have the same effect, but we don't have place to exile people to anymore.

mcmoor··on YouTube addresses lower view counts which seem to be caused by ad blockers
I've heard that it's not actual dislike count, but extrapolated data contributed from people who installed the extensions. But I've also heard that some channels have compared it to their actual dislike count and it only differs little.
mcmoor··on YouTube addresses lower view counts which seem to be caused by ad blockers
Likes to dislikes is an even better signal. Shame on YouTube for removing that.
mcmoor··on Life, work, death and the peasant: Rent and extraction
It's just funny since his blog is the entire reason I learned about the difference of adjunct and tenured professor, and why a big problem in academia is that they tenure less and less and rely on lots of adjunct professors instead.
mcmoor··on Many hard LeetCode problems are easy constraint problems
For the love of me I still can't consistently solve dynamic programming problems. Because "write a clever brute force solution that can be cached" is so broad that there are tons of variations out there, and a slight twist can bring you out of the loop fast.
mcmoor··on Many hard LeetCode problems are easy constraint problems
Yeah I think the trivial solution is always harder complexity and the main challenge is to lower it. Either from NP to P or from n*2 to n log n.
mcmoor··on Many hard LeetCode problems are easy constraint problems
I hate when it asks for a memorized specific problem, but most of the hard ones I found needs a clever twist of a well-known algorithm, and I still struggle at that too for hard LC.
mcmoor··on Life, work, death and the peasant: Rent and extraction
I found the one for Sparta too emotionally charged for my interest. But I really really endorse most of the other ones especially ones touching in economics and logistics of ancient world.

(Btw he's not a tenured professor, much to his chagrin, he's an adjunct professor. This is exactly why he wrote A LOT about broken academia system too.)

mcmoor··on Minesweeper thermodynamics
Yeah I've debugged another game that attempted this and this system resulted in the game lagging as hard sometimes.
mcmoor··on F-Droid site certificate expired
In my country's ISP, they outright force you to see an ad for 5s before you can open a webpage sometimes.
mcmoor··on A renovation project in Turkey led to the discovery of a lost city (2023)
> And that these were necessary only because semi-regular invasions were basically a fact of life back then.

I remember my Turkish guide proudly saying that these dwellings have not been settled for centuries "because we were never invaded again so we don't need to hide here anymore".

mcmoor··on Google admits anti-competitive conduct involving Google Search in Australia
The sane calculaltion is to make the fine amount equals to (loss to society or profit to corporation) / (chance of getting caught). In some cases, I guess it can be argued that chance of getting caught is so small that the fine should bankrupt someone, but still we should not do it arbitrarily just because the target is a big corporation.
mcmoor··on When did AI take over Hacker News?
After GPT-5 release I realized it's actually winding down quite significantly. I don't really know if it's actually the normal rate or the hype is really declining.
mcmoor··on The demographic future of humanity: facts and consequences [pdf]
This article [1] claims that it's actually still quite higher than replacement, to make people around ancient Mediterranean have to resort to various kinds of birth control (be it violent or non violent). Medicinal revolution do lowers death rate significantly but I guess the reason why we haven't normalized late/late marriage pattern as birth control until recently is because of abundance of resource resulted by industrial and agricultural revolution.

mcmoor··on The demographic future of humanity: facts and consequences [pdf]
Any data for this? I think this maybe the real answer because unlike other explanations, this one can actually acquire proof from before modern ages. Simply because it's known that cities fertility rates were always negative and have to constantly pull people from countryside.
mcmoor··on Stone blocks from the Lighthouse of Alexandria recovered from seafloor
Thanks! I didn't think about that dimension. The information resolution still feels a bit too low for my liking (I thought it'd help a ship zigzag with precision), but I guess it's much much better than none.

I just realized that if there's 3 of them, it'd constitute an ancient GPS isn't it. Or even only two?

mcmoor··on Stone blocks from the Lighthouse of Alexandria recovered from seafloor
It's only a 1 bit signal that says "don't come here" isn't it? I've seen claims that lighthouse helps ships somehow navigate difficult waves and I'm always curious how exactly one high lamp do that. Saying that it "guides" is a bit of an overstatement isn't it? Like saying that a road sign saying "dangerous hole here" guides riders navigate the road.
