46Bit··on The Helicopter with Radioactive Blades
The article is very vague on how the radioactivity allows detection of leaking gas.

The video at the bottom explains from 7:50 in. Gas pressure pressing on a spring holds a radiation shield in place. If the gas leaks the shield moves and the radiation can be detected.

46Bit··on Folk are getting dangerously attached to AI that always tells them they're right
Life in the moment is a lot easier if you don't second-guess yourself. I think this is why many people (and probably ~all people, if tired) crave simplistic solutions.

I like to make a subagent take the "devil's advocate" take on a subject. It usually does all the arguing for me as to why the main agent has it wrong. Commonly results in better decisions that I'd have made alone.

Asking the agent to interview on why I disagree helps too but is more effort.

46Bit··on Exercise can be nearly as effective as therapy for depression
Overeating is often a coping mechanism. It’s really hard to displace unless your life is going fantastic. Even with GLPs.
46Bit··on Logging sucks
What we're doing at Cloudflare (including some of what the author works on) samples adaptively. Each log batch is bucketed based on a few fields, and in each bucket if there's lots of logs in each bucket we only keep the sqrt or log of the number of input logs. It works really well... but part of why it works well is we always have blistering rates of logs, so can cope with spikes in event rates without the sampling system itself getting overwhelmed.
46Bit··on UK minister ducks cost questions on nationwide digital ID scheme
It’s worth remembering that the status-quo is itself expensive.

GOV.UK Verify, the example I know best, burned through a lot of money trying to do digital identity without actually doing ID cards.

46Bit··on Collaboration sucks
> if they can't explain what they want to do clearly and why, it probably shouldn't be done. Quality goes up by slowing down.

I kind of agree. Without what you describe, teams often get lost. But I’ve also seen that approach keep teams stuck in comfortable local minima. Sometimes you’ve got to take risks.

46Bit··on My Failures Onboarding at Splunk
I agree, it's an interesting view. I found it quite positive about the culture in that part of Splunk. The writer parachuted in, threw their weight around, bruised a bunch of people, but lost out to another manager who openly acknowledged the contributions of their people.

Or worse. Or no services at all.

46Bit··on Das Blinkenlights
The effect is really cool. I like the idea of visualizing data flowing through work systems like this. I think I'll go for 3D-printed or laser-cut panels instead though - would work out cheaper. Thanks :)
46Bit··on Studios: Please Don't Spoil the Movie We Are Seated to See
I saw that without any spoilers and it was one of the weirdest movie experiences I’ve ever had.
46Bit··on Insider trader had all the answers
Ordering satellite imagery and counting cars is just a weekend project. The last time I looked at ordering imagery, the main obstacle was the minimum order size, so it'd actually scale better for monitoring every store car park than for looking at a single car park.
46Bit··on Working in the office 5 days/week to build company culture is a myth: PwC report
> You can’t form relationships that way

Plenty of millenials and Gen Z can

We've been building groups online ever since we were little

46Bit··on How we migrated Gov.uk notify to AWS elastic container service
It's pretty normal for ordinary government workloads in the UK, or at least it was at GDS. Using niche suppliers who cater to government paranoia is expensive, and they're usually much less mature than hyperscaler platforms. It's also open for debate whether those niche, inflexible suppliers result in a genuinely more hardened target or not.
46Bit··on Redis is forked
Anecdotally, I know several teams likely to adopt OpenTofu when state encryption ships https://terrateam.io/blog/opentofu-feature-preview-state-enc...
46Bit··on We’re opening up access to Gov.uk forms
Umm, GOV.UK uses Google Analytics, Fastly CDN, AWS containers, and I believe is developing an app.

(I worked at GDS until two years ago.)

46Bit··on Influxdb made the switch from Go to Rust
Influx is a full time series database. It's less opinionated than Prometheus.

46Bit··on Silicon Valley “Pronatalists” Oppose Remote Work Despite Boosted Fertility Rates
Indeed. Working from an office without daycare would be similarly unproductive.
46Bit··on Ferromagnetic half levitation of LK-99-like synthetic samples
(Not a scientist, just a hobbyist.)

Red phosphorous is an ingredient in the original paper’s process.

https://patents.google.com/patent/US6110438A/en claims that black phosphorous can be made from red phosphorus using a vacuum and hundreds-of-C temperatures. Both of which people have done.

Seems very possible.

46Bit··on Observation of zero resistance above 100 K in Pb₁₀₋ₓCuₓ(PO₄)₆O
Agreed. Even the 100K zero-resistance claim isn't holding up to scrutiny https://nitter.net/condensed_the/status/1686895266329174016 https://nitter.net/condensed_the/status/1686901855358427136 https://nitter.net/condensed_the/status/1686832552252784641
46Bit··on Observation of zero resistance above 100 K in Pb₁₀₋ₓCuₓ(PO₄)₆O
https://nitter.net/condensed_the/status/1686895266329174016 claims a linear representation of the same data. Still no convincing discontinuity visible.
46Bit··on “We are not cheating” (YH Kwon superconductor comments)
I hear what you're saying, but it's not like the sample would need hand couriering a great distance. They're in Seoul, home to a large number of universities [1]. If the discovery is real then I'd hope another university there validates it soon.

46Bit··on Global heat in ‘uncharted territory’: 2023 could be the hottest year on record
Agreed. It reads like they opened the fridge for awhile to remove the cardboard and that cooled the room down. Problem being that the fridge will then heat the room more to cool itself back down.
46Bit··on Changing my mind on remote, moving the team back to San Francisco
> Do you pay your entire team enough to afford 3 bedroom spaces adequate for a family in the city?

It's critical for their careers to not have families. Instead they can have beers with their colleagues.

46Bit··on Ask HN: Has anyone here left the big city in pursue of a simpler life?
> good middle ground is to move to the outskirts of a smaller town with some sort of draw

Things can be different in Europe to the US but this is still key. If you move to a low cost of living, relatively anonymous town then things are going to be pretty average. If you’re an educated, intellectual engineer than can be kinda stifling. You need people you can relate to, which basically puts you back in MCOL/HCOL.

46Bit··on The era of cloud colonialism has begun
Typical reactionary nonsense from The Register. Obviously big tech isn’t a charity, but the article talks about 600M without even electricity and then effectively claims they’d be better off without infrastructure investment.
