curiousObject··on Crystal Ball Trading Game
>if you are not willing to cheat, you are leaving an edge to those who do.

You don’t have to be the best player or to cheat on the poker table for +ev

You have to be better than the bad players, and know when to fold against a better player

You will make less profit than cheats. But, you won’t have to cheat

curiousObject··on A “meta-optics” camera that is the size of a grain of salt
If that’s true, maybe it would allow you to put a 10,000 camera array (100x100) on a smartphone, and do interesting things with computational imaging?
curiousObject··on Huawei developing SSD-tape hybrid amid US tech restrictions
This idea adds a fast SSD cache to a slow access bulk archive.

Obviously that cache can massively accelerate repeated access to the same data, and reduce tape wear and mechanical wear and energy usage.

But I think the critical issue is where you want the cache to be. Because end point devices already have local cache.

So this product only seems to have a big advantage on applications where you expect many unique users to access the same archive data for the first time, and within a short period of time before it expires from the tape drive’s SSD cache.

This is why I think it’s a small niche. Maybe too small to be worthwhile.

Edit: it also has the disadvantage that the first few devices to try to access the data would have a huge delay for a minute or more while the data is located on the tape. It’s also vulnerable to DDOS by attackers requesting random cold data, to fill the SSD.

curiousObject··on Huawei developing SSD-tape hybrid amid US tech restrictions
Up to 2 minutes seek time for cold data. Very niche.
curiousObject··on 1 in 6 Companies Are Hesitant to Hire Recent College Graduates
I guess we all know the problem: the money they might save the company on salary is nothing compared to the money they could cost you in every other way.

The chance of hiring a genius is tiny.

So, hope someone else performs that experiment for you.

curiousObject··on SpaceX Falcon 9 booster 'tipped over' into the ocean during landing
This is the second recent glitch in a SpaceX mission. The other, more serious, was the failure of a Starlink Falcon 9 to quite reach a viable orbit because of an oxygen leak on an engine.

These minor blips only stand out in the context of SpaceX’s unprecedented consistency, which surpasses anyone else. But, if they have another snafu soon, maybe it could hint at a slight decline in their normal technical excellence?

Edit : OTOH, this was launch 23 of that booster, as mentioned by @gregoriol, so I for one might see that as a successful test discovery of the reuse limits of the structure. And also, the F9 that didn’t reach orbit probably wouldn’t have threatened the lives of a human crew, although it would have scrubbed their mission.

curiousObject··on Kim Dotcom's extradition to the U.S. given green light by New Zealand
Kim DC is not a likeable or admirable person, but this vindictive pursuit seems even worse.

It appears very similar to the treatment of Ross Ulbricht, Assange, maybe even Snowden?

These are the equivalent of white collar crimes (typical massive frauds from the finance sector, etc) but they are getting a blue collar punishment of decades in jail that a successful and persistent street drug dealer could receive, NOT the few years in comfort camp prison that white collar frauds usually get.

curiousObject··on NASA likely to significantly delay the launch of Crew 9 due to Starliner issues
Would they be more willing to bring Starliner back with one crew member aboard, instead of two?

That is how bad this situation is becoming.

curiousObject··on Retired Astronaut Admits Boeing's Starliner Has Trapped Crew in Space
This would be similar to describing any of your comments as “on behalf of the Hacker News community”. You probably would object to that description and it certainly wouldn’t be true.
curiousObject··on Retired Astronaut Admits Boeing's Starliner Has Trapped Crew in Space
“Admits” implies that this unnamed retired astronaut was not being honest before.

Probably nobody asked them before. They’re just giving their honest opinion, and they don’t deserve this implied insult.

Toxic commentary, about a serious issue which demands calmer criticism

And, the only real reporting done was from The Atlantic, not this clickbait mill.

curiousObject··on Atari 520ST Review in Creative Computing – By Paul Lefebvre
Sad story. There’s a Wikipedia page for him which also remembers his colleague, Derek van Alstyne, who died alongside him, both caught by bad luck in a building collapse during the quake: https://en.wikipedia.org/wiki/John_J._Anderson

Good heuristics. Also that must not be a mainly downward rapid movement, which probably only means you just dropped your phone.

curiousObject··on Job Titles Are Bullshit
Yeah, quite so, but that is probably not a rational state of mind to keep up for the long term. OP sounds like they are caught in such a contradictory viewpoint: they hate that everyone cares about job titles, yet they themselves care strongly about job titles

For e.g. “I quite like knowing where folks sit on the org chart compared to me”, & puzzling over the ‘meaning’ of “senior” in a job title!

curiousObject··on Job Titles Are Bullshit
This person says that job titles are bullshit (I agree, generally), but expressed many reasons why they care strongly about job titles

Isn’t this contradictory?

curiousObject··on What's in Those Suitcases? $125M in Cash
>“Britain for years has been trying to stamp out money being laundered through its banks and real estate, particularly from overseas. Financial crime lawyers say the tightening in rules and laws has made it harder for crime gangs to wash their money in traditional ways such as through shell companies or small businesses.”

>”Bitcoin also has proven to be problematic for criminals. Physical transportation, including hiring couriers for relatively small sums, has become an alternative.”

Ironic, about Bitcoin not being most effective for laundering criminal proceeds, the opposite of popular opinion.

Although I would suggest that Britain has been “trying” to stamp out money being laundered through its banks and real estate. Because many are loving the influx of cash into the property market, without a care where it’s coming from.

curiousObject··on The Right Chemistry: Reflections on the manufacture of mirrors (2022)
Mirrors had an impact like VR, but 200-300 years ago.

They were a clear reflection of reality. Previously the best you could get was a calm pool of water.

You can probably understand how mirror makers would accept being poisoned by mercury to create that experience.

curiousObject··on My $500M Mars rover mistake
> It started up fine.

Thanks. I understand that better now. The spacecraft did start up, but it seemed as if it could be badly damaged because they were not receiving any telemetry data

curiousObject··on My $500M Mars rover mistake
The story is compellingly written, but I thought it was also confusing.

It sounds as if this team made several mistakes, not just one mistake. It's also not clear if the result of these mistakes was that there might be real damage to the spacecraft, or if the result was just wasted time and hours of confusion about why the spacecraft wouldn't start up.

The first mistake is they didn't realize that the multimeter was not only measuring, but it was also completing the circuit.

That sounds like a real bad idea. But if it was totally necessary to arrange it like that, then that multimeter should never have been touched.

That's not just one guy's error. It's at least two guys at fault, along with whoever is managing them, and whoever is in charge of the system that allows it.

The second mistake is with the break-out-box. They think he misdirected power wrongly into the spacecraft. Then they jump to the conclusion that has generated a power surge which has damaged the spacecraft, because it won't start up.

But they're not sure where the power surge went and what might be damaged. Anyhow they're wrong.

The reason the spacecraft won't start up is just because he took the multimeter out of the circuit before the accident.

I'm still sort of confused about what happened or if they ever really figured out what happened.

He said "Weeks of analyses followed on the RAT-Revolve motor H-bridge channel leading to detailed discussions of possible thin-film demetallization".

Does this mean that they decided that the misdirected power surge might have flowed into the RAT-Revolve motor H-bridge channel and damaged that?

curiousObject··on Unauthorized "David Attenborough" AI clone narrates developer's life, goes viral
This demonstration is respectful. It’s funny. It’s obvious parody.

But, the tech can be used to make disrespectful content.

Look forward to: David Attenborough narrates porn.

I don’t know what we can do. Ain’t no easy answers. But do we want courts and $Lawyers deciding what is respectful?
