gvb··on What do you think the FTX Netflix docuseries will be called?
Bad FTX
gvb··on Musk is now working out of Twitter headquarters, thanks employees for long hours
"Working Hard is not the same as working smart" https://steveblank.com/2016/09/07/working-hard-is-not-the-sa...

[Steve] pointed out to [the CEO] that what he was watching was that his entire company had bought into the “culture of working late” – but not because they had work to do, or it was making them more competitive or generating more revenue, but because the CEO said it was what mattered. Every evening the VPs were waiting for the CEO to leave, and then when the VPs left everyone else would go home. Long hours don’t necessarily mean success. There are times when all-nighters are necessary (early days of a startup, on a project deadline) but good management is knowing when it is needed and when it is just theater.

gvb··on FTX to file for U.S. bankruptcy, CEO resigns
Binance triggered the collapse, but the stage was set by FTX/Alameda by "creating its own token" (per "The FTX-Alameda nexus") and "loaning" $10bn to Alameda using their "own created token" as the backing collateral.

Of course, there's a risk that the hedge fund could lose some or all of the customers' funds. And the exchange promises that customers can have their assets back on demand, which could be a trifle problematic if they are locked up in leveraged positions held by the hedge fund. But this is crypto. There's an easy solution. The exchange can issue its own token to replace the customer assets transferred to the hedge fund. The exchange will report customer balances in terms of the assets they have deposited, but what it will actually hold will be its own token. If customers request to withdraw their balances, the exchange will sell its own tokens to obtain the necessary assets - after all, crypto assets, like dollars, are fungible. ["The FTX-Alameda nexus" - emphasis mine]

gvb··on Ask HN: Why do all the home flippers flop?(Zillow, OpenDoor, RedFin)
The individual home flipper working out of their own money is going to only choose projects that look very favorable. The corporation is going to hire a manager and that manager will probably be told to close a certain amount of deal flow and will feel pressured to close deals that aren't very profitable and not have such a financial incentive to keep the deals profitable.

The corporations trained an AI on data that showed a strong upward trend in selling prices. The result is the AI predicted that most flips would be profitable and thus almost always said "buy."

This worked until the housing market slowed down, the upward trend in selling prices slowed (and reversed in some cases), and the AI predictions of profitability became wrong.

No.

a) The mirror would need to be continuous. No gaps.

b) The mirror would have to be perfect. No dirt. No smudges.

More likely disabling them to prevent them from monitoring (naval) vessel traffic:

"Packed with sensors, the fiberoptic lines measured environmental conditions and fish migration, recording images and sound, and sending all the information back to shore."

"They could also be used as drifting hydrophones to listen for passing vessels for security purposes."

gvb··on Ask HN: What Is Serverless
Its a programmable calculator on steroids.

You create "one liner" programs (lambdas) that do mathematical operations like you would with a programmable calculator, including saving to memory and recalling from memory. You can then chain together the various "one liner" programs (composability) to make a complex program that performs the calculation that you need.

gvb··on Ask HN: Is it possible to create a image processing based lie detector?
https://www.technologyreview.com/2020/03/13/905323/ai-lie-de...

Skip to the end for the tl;dr:

The foundational premise of AI lie detection is that lies are there to be seen with the right tools. Psychologists still don’t know how valid that claim is [...]. The promise of a window into the inner lives of others is too tempting to pass up, even if nobody can be sure how clear that window is.

“It’s the promise of mind-reading,” says Wilde. “You can see that it’s bogus, but that’s what they’re selling.”

gvb··on Arm loses 40% of UK staff gained in SoftBank years
https://archive.ph/SA0pH

"When Japanese conglomerate SoftBank bought the company in 2016, it made a commitment to double the chip designer’s 1,770 British workforce over the following five years. It succeeded, according to figures released by Arm, and by September of last year British staff peaked at above 3,500, with a total of 6,950 globally."

"Since then, the company has cut 18 per cent of its global workforce, with the UK taking a larger hit proportionally. The reduction was driven in part by management refocusing the business and exacerbated by an exodus of staff unsettled by uncertainty about the company’s future, according to former employees who spoke to the Financial Times."

gvb··on The Russian economy will ‘die by winter’ because of the military mobilization
https://archive.ph/G2Iy8

This is very scary; if the economy is totally disrupted, the Russian "Federation" could splinter into a mess of countries/fiefdoms, many with nukes.

Russia currently spans eleven (11) time zones. With total economic chaos, there will be no way to hold that together as a single "Russian Federation." It was dicey back in 1991 when the USSR dissolved - this could be worse.

gvb··on Ask HN: Why aren't more software engineers contractors? tax savings?
Contracting can also be lose-lose:

1) Software engineers have to be salesmen as well to find companies willing to pay them well for jobs. Software engineers that can sell themselves do very well. The rest do not. Rule of thumb is that "sales" for contractors is at least a half-time job.

2) Companies do not like to hire contractors for critical software because (a) they are unable to tell the difference between a good engineer and a crap engineer until it is too late and (b) if the contractor disappears, they are stuck with software that may or may not be maintainable and no way forward other than hiring another contractor (goto (a)).
