oa335··on No Signs of AI Payoff Outside the Tech Sector
I was too specific, it was more about computing generally as opposed to "personal computing".
oa335··on No signs of AI payoff outside the tech sector
Came here to say this as well.

It took decades for effects of personal computing to show up in aggregate statistics.

See:

https://en.wikipedia.org/wiki/Productivity_paradox and https://dl.acm.org/doi/10.1145/163298.163309

edit: My comment is not exactly right, its more about general computing rather than personal computing

can you please elaborate? does duckdb support querying custom storage formats?

what app do you use on your phone to communicate with yoir server? just a terminal emulator?

How precisely do you do this? I'm interested in setting up a similar system, and I keep getting tripped up on how best to share information with the agent in a way that doesn't compromise security but is still easy to use.

because it is useful and interesting. why should they rewrite the project without LLM input?

oa335··on Kobo can run apps now
what a horrible attitude, especially for a forum dedicated to "hackers".

the code is open source, why dont you show us what a quality test suite looks like?

oa335··on The Fabled Flatbreads of Uzbekistan (2015)
that websites estimates are definitely too low - e.g. there are definitely more than 40 Uzbek people in Chicago... I've been to 3 uzbek restaurants in Chicago proper myself.
oa335··on The Fabled Flatbreads of Uzbekistan (2015)
"There's apparently only ~2000 Uzbek-Americans in all of northern IL"

where did you get this number? does that include chicago, because i live in Chicago area ... seems low.

oa335··on SWE-1.7 Reach Near GPT 5.5 and Opus Intelligence
> "A company whose first demo was completely fraudulent"

Could you expand on this?

oa335··on Costco is the anti-Amazon
Agree 100%. Costco exemplifies american dream... recent immigrants perusing well-stocked aisles, friendly employees, ample parking, cheap tasty hot dogs, etc.
oa335··on GLM 5.2 beats Claude in our benchmarks
> it costs >1000% to run inference

do you have a source for this claim? i thought LLM providers earn high margins from inference (charged by token). is this no longer the case?

oa335··on Total Iran Economic Damage Estimate
"Our most likely estimate is that replacement costs are approximately $91 billion. Military and strategic assets — nuclear facilities, missile and drone production infrastructure, air bases, naval vessels, and air defense systems — make up roughly half that total, at approximately $46 billion, which is equivalent to 4-6 years of Iran’s pre-war defense budget"

How exactly did they arrive at this estimate? I would like to see a building-by-building breakdown, or at least a methodology. Feels very vibe-researched tbh.

oa335··on There Is(Ǝ) – Such That (∋)
as a math major i had the same confusion; for such that i use "s.t.". but apparently peano used ∋ to mean such that:

oa335··on pg_durable: Microsoft open sources in-database durable execution
> 8 queries implies 8 tables, which is well under the limit for both Postgres and MySQL where the planner may give up and choose a suboptimal plan.

I'm not sure thats true for Postgres. optimal join ordering is np-hard, and finding an optimal join requires exhaustive search through n! combinations (n=number of joins) - thats why postgres generally uses heuristics to figure out join order. 8 is also the default value of "join_collapse_limit" setting in postgres, so it can't ever reliably optimize over 8 joins at a time. Additionally, postgres starts using "genetic algorithms" aka testing random combinations of joins with 12 joins by default (geqo_threshold setting).

I generally agree its better to use database to its fullest, but I would say 8 joins is probably the "limit". Internally at work I've advised teams to try to avoid anything more than 6 joins for "hot-path" queries.

oa335··on Pentagon raised threat of Israeli spying on U.S. to highest level, sources say
compare list of conflicts in europe to those in middle east over past from 1000 AD - 1900AD:

https://en.wikipedia.org/wiki/List_of_conflicts_in_Europe

in particular state formation in late medieval and early modern europe saw immense bloodshed and turmoil.

middle east was comparatively peaceful in contrast, especially post mongol conquest.

e.g. compare 1700s and 1800s europe to middle east

Can anyone explain why I would want to use this over an orchestration tool that lives outside the DB? Read through the Readme and some of the examples, I still don't get it.
oa335··on Why China got rich and India didn't
> Those numbers also show why the “wealth transfer from India” is mostly fake. India and China were both at a subsistence level. There was no meaningful wealth to transfer.

Can you expand? What was the EIC doing in India?

oa335··on Morningstar values SpaceX at $780B, half its IPO target
Not an Elon fan, but markets dictate the value, not analyst reports or "fundamentals". The stock is simply worth whatever people will pay for it. The fact that people are paying an implied valuation of 2T for it currently is a strong signal IMO.

nice work! we have handrolled something similar at work.

do you have any perf metrics? throughput, end-to-end latency, etc?

why do you believe you and and your family (parents and sibling) belong in the USA?

oa335··on WH proposes rules giving political appointees final approval on research grants
it depends greatly on the majority though. e.g. he believes democracy should be suppressed ("crushed") in Muslim- majority nations, etc.

> People really need to read their history.

agreed.

but i bet i can make a bunch of confounding factors appear.

from 1800 to 1870 gdp per capita growth rate was about 1.1 percent.

from 1870 to right before great depression growth rate was about 1.6 percent.

from start of great depression until 2022 it was about 1.8 percent.

economy and standards of living have gotten better faster as the state has gotten more bureacratic.

oa335··on Raft Consensus with a Minority of Nodes
excellent article.

> The key correctness insight is this: any two majorities of nodes must overlap in at least one node. So between any two consecutive global state changes — whether two commits, two leader elections, or one of each — at least one node participated in both.

intuitively makes sense, but would be nice to see this result explicitly derived or illustrated the same way the fano planes were.

oa335··on There are now more ETFs than stocks in the US
yes, there is counterparty risk with both etfs and mutual funds. in general, stick to the well regarded issuers or fund managers. vanguard is the best imo, they do a lot to protect their shareholders.
