datalopers··on Elizabeth Holmes sentenced to 11 years in prison for Theranos fraud
Theranos raised $1B; FTX raised $2B. So we can assume that SBF gets 22yrs prison right?

datalopers··on GitHub CTO – Biggest architectural mistake was going full microservice
Yep. Microservices were pushed hard by Martin Fowler who gives terrible programming advice that always yields extremely lucrative returns for cloud platforms.
datalopers··on Making a Go program faster with a one-character change
That's not technically correct with regards to PHP. Your statement that any changes to $arr1 or $arr2 only impact the one in question, however, is accurate. If no changes are made they still refer to the same data in memory. It's copy-on-write semantics.

$arr1 = [1,2,3]; // $arr1 is a pointer to a zval array [1,2,3] and refcount:1

$arr2 = $arr1; // $arr1 and $arr2 are pointers to the same zval array but incremented refcount to 2.

$arr2[] = 4; // at this point, $arr2 creates a new zval array, copies over the data from the first, sets the recount to 1, and appends int(4). The [1,2,3] array has its refcount decremented to 1 as it's still referenced by $arr1.

datalopers··on A sleuth’s guide to the coming wave of corporate fraud
It's an oversimplified example to illustrate how revenue-multiple valuations lead to perverse but rational investment strategies.
datalopers··on A sleuth’s guide to the coming wave of corporate fraud
I'm not sure if this is fraud, or simply how VCs operate, but we're going to see a massive collapse of SaaS startups and their customers in the near future. This is why:

1) Tech valuations over the past ~5 years were based entirely on annual revenue multiples. 25x was the norm, while 50-100x wasn't hard to find.

2) Let's say your VC firm owns 5% of CompanySaaS, which you paid $1M for, and the company is valued at 25x ARR ($800k * 25).

3) Now you invest $100k in CompanyWhatever. As their VC and valued advisor, convince them they should spend $100k/yr utilizing CompanySaaS's products.

4) CompanySaaS is now worth $900k * 25 (probably higher multiple since revenue is growing so fast), or $22.5M, and you just turned $100k into $125k.

Rinse and repeat. It's a self-perpetuating bubble, and it's going to come crashing down hard. It's already happened but they've still got enough runway for another 6-24mos.

datalopers··on I decided to stop working on Mighty
He shutdown Mighty to launch an AI image generator. Anytime you’re told someone is smart or clever, remember they aren't.
datalopers··on Hard Reset
Why is the CEO pulling a salary at all? Or are they not the founder and were brought in?

Founders just take the bare minimum to survive, anything else is just irresponsible.

Good luck
datalopers··on FTX faces potential hack, sees mysterious outflows totaling more than $600M
SBF and Caroline (and probably Trabucco) probably already on their way to non-extradition countries and taking what little cash remains with them. They'll end up in prison if they don't.

datalopers··on FTX tapped into customer accounts to fund risky bets, setting up its downfall
> nothing to do with crypto, it has to do with people sending their money to a con man

You've just described 99% of crypto though.

You're making the assumption that annualized revenue hasn't already dropped precipitously due to a loss in advertising dollars, and the bar for subscriptions to reach 50% is rapidly lowering.

datalopers··on US annual inflation declines to 7.7% in October vs. 7.9% expected
I don’t think you understand how bonds work. However I do agree that yields will increase and this is temporary.

Why would you suggest buying a bond on the exact day that yields just plummeted.
datalopers··on Zuckerberg's leaked email on VR strategy (2015)
VR gaming is so bad. My bet is it instead takes off in business, social media/doomscrolling, and AR assisted technologies and productivity.
