__s··on The Ploopy A+ Trackball Is Here
Took about a year for my Kensington slimblade to start double clicking. Many others reporting the same
__s··on NP-overrated
Same with c++ stl unordered_map
__s··on Introducing Toast 1
ime google ai is wrong often enough that I'm still doing that to verify its results

At least validation seems faster than without, but you get what you pay for when it comes to llm intelligence

__s··on NP-overrated
Depends on comparison function. In clickhouse-c for type name lookup it's strcmp so I use generated hash table with no collisions & reusing cityhash function since we have it handy: https://github.com/ClickHouse/clickhouse-c/blob/4bdd89a02438...

Benchmarked an order of magnitude faster than linear scan or binary search. I agree with your general sentiment tho, which is why I measured

__s··on pg_clickhouse v0.10: Subquery pushdown and 1000x faster TPC-H queries
They're not really compatable. Your link already compares pgrust & clickhouse. A comparison would not be by using postgres_fdw from postgres to pgrust
__s··on “Code was never the hard part” is an insult to all programmers
Yes. I've also heard it said "code was never the bottleneck"
__s··on Shopify replaced Redis with MySQL for inventory reservations–and it scaled
Example of their culture: https://x.com/tobi/status/1909251946235437514
__s··on Mario Meets Pareto
It's a fair point that such an environment will be different than playing against other humans
__s··on Mario Meets Pareto
> You probably won't pick a driver sitting on the edge of the frontier because you want some balance between speed and acceleration

for super mario kart speedruns go with bowser/dk: https://www.speedrun.com/smk/runs/zp68nr8m

That seemed to hold up for Mario Kart 8 too going with Bowser at the edge of their pareto frontier, https://www.speedrun.com/mk8

needing acceleration is a skill issue

__s··on Branchless Rust: Making a Filter 4x Faster by Removing an If
I just scrolled through & read the code snippets. Interesting enough solution at end
__s··on Pareto Front
Trouble with fonts is sometimes monospace good, sometimes monodpace bad

Anyways I'll namedrop Iosevka as perfect monospace font for working on 13" laptop

__s··on Bending Spoons makes first post-IPO acquisition with $1.3B Airtable deal
One group I followed switched to LinkedIn
__s··on Why is it all in the kernel?
It doesn't, it just loses your session
__s··on SQLite Critical CVEs or LLM Slop?
Haha, I was reading your comment as praise for Greg until the end
__s··on Our position on open-weights models
Seemed to've worked out pretty well for Uber
__s··on Kimi K3 exploited the latest Redis server
Yep. For managed postgres our threat model is to assume vm is compromised. It's paid off, just earlier this year there was RCE fix in PG 18.4
__s··on Why do you suck at juggling now?
Every year I just say I want to improve my work life balance & work out more

Doesn't happen, but hey at least I'm being honest about what I'd like to improve

__s··on Codex Micro
Or just order any macropad
__s··on How to stop Claude from saying load-bearing
I find it irritating with humans. "last but not the least" always distracts me as I then consider maybe the last item _is_ the least. & what is with everyone saying they want to "double click" into meeting items
__s··on We scaled PgBouncer to 4x throughput
you encode information in the token, this was a motivation for postgres to remove 32 byte cap on tokens: https://www.postgresql.org/message-id/508d0505-8b7a-4864-a68...

See from slide 26 https://www.pgevents.ca/events/pgconfdev2024/sessions/sessio... Jelte's a pgbouncer maintainer, video of a talk on this by him: https://www.youtube.com/watch?v=X-nCHcZ6vQU

__s··on We scaled PgBouncer to 4x throughput
Yes, https://www.pgbouncer.org/config.html#section-peers
__s··on We scaled PgBouncer to 4x throughput
SO_REUSEPORT[1] pretty much does all we want in kernelspace vs unnecessary userspace hop inbetween. These all run on same VM

__s··on The glass backbone: Why the Army's logistics will break in the next war
If it weren't for those bone spurs maybe that war wouldn't be so forgotten
__s··on Why Vancouver is always a stand-in for San Francisco in movies and TV shows (2021)
B-roll
__s··on Better Auth is joining Vercel
Silent execution of tremor was a pain in the ass trying to upgrade to nextjs 15 / react 19: https://github.com/tremorlabs/tremor/issues/148
__s··on Why low-latency Java still requires discipline?
Yes. & in the end my experience has been that you can write low latency code with gc, but only by expending more effort than it'd take to use manual memory management
__s··on Fable 5 On Vending-Bench: Misbehaving, With Plausible Deniability
Fable's spatial reasoning is much better. Over the weekend I had opus looking into a blank textbox issue[1] which it was spinning on for a few minutes, switching to fable immediately fixed

But yeah opus often the better workhorse given price gap

__s··on The Fear of Dying Before You Become Yourself
I've experienced the opposite: wishing I were dead so life wouldn't go on with me falling into just another glum existence. That at the emotionally present moment I snapshot it, preventing inevitable dullness that time moves on

Unfortunately here I am, life moves on, now I'm just wasting away on HN

__s··on I wanted to be Anthony Bourdain–until I met him
Haha I'll be lucky if I can gather 2m & still have sacrificed much work life balance just because my type of stupid is an obsession
__s··on PostgreSQL and the OOM killer: Why we use strict memory overcommit
> I have yet to see a program that silently handles allocation failures and doesn't crash

Postgres handles allocation failures
