cavisne··on The current layoffs were orchestrated by hedge funds
Blaming hedge funds is a misdirection. Google and Facebook have dual classes of shares and all shareholder governance is controlled by the founders.
cavisne··on For U.S. companies, the race for the new EV battery is on
As always with the EV industry the non-Tesla entities are following such a weird strategy it almost seems like fraud.

GM sells two EVs, one that spontaneously combusts (bolt) and one that is the least efficient EV sold (hummer).

How about they fix their efficiency and reliability before trying to make a different battery chemistry work.

Likewise the new EV credit prioritizes inefficient vehicles by having a higher limit for large suvs and trucks.

We should just stick to technology that works, and focus on efficiency and scaling. Any new chemistry will still be a science experiment in 2030 (when allegedly gas vehicles will stop being produced)

cavisne··on Alameda County admits tallying error in ranked choice voting
And the fact that the vast majority were for one candidate. Looking at pictures of the example ballots it’s a confusing format optimized for voting machines, not humans.

I really don’t understand the American obsession with voting machines, I believe there is always a manual count anyway and American election counting is extremely slow anyway.

cavisne··on Google removed my Yubikeys from a Google account 'just to be safe'
Businesses just ask for a social security number, and a random one is provided.

So they can plead ignorance.

cavisne··on Becoming financially independent as solo quant
Agreed.

I did originally buy into the explanation that they collected/digitized stock data that is no longer available.

But really it’s more likely to be some sort of fraud.

cavisne··on YouTube Transcript – read YouTube videos
Nothing too exciting, just “summarize this” followed by the transcript in quotes, it works very well
cavisne··on YouTube Transcript – read YouTube videos
This script for whisper.cpp works really well

for my purposes I changed the output from subtitles to txt (so I could pipe the result into chatgpt)

cavisne··on Tell HN: Google is correlating location data to your IP
Google Maps on iOS asks to track your location in the background by default.

Apple tracks your location as long as Location Services is turned on.

cavisne··on Warning – Google suspended GCP services for 'verification', lost my business
The frameworks largely exist, the above situation is like if you rented an office building and then started running an unlicensed side business out of it. It’s just a lot rarer (cloud computing has a much lower cost of entry then a commercial lease).
cavisne··on Stripe account suffered a card test
Years ago when i ordered from a site they had a system where they would charge you slightly less than the price on the order, but you had to quickly verify the last 2 digits. Ie a $100 item and they would charge you 99.97, and auto cancel the order if you cant provide the actual cost (from your internet banking). Since credit card charges appear instantly this was pretty simple.

I'm surprised I've never seen such a system since, it seems very effective against stolen cards.

cavisne··on SBF posting 1 letter tweets to evade delete detection bots?
Worth adding that “negative pieces for 10 years” is not an opinion. It was official NYT editorial policy (original tweet now deleted)

cavisne··on A sleuth’s guide to the coming wave of corporate fraud
The past few years have been great for scammers though

https://www.justice.gov/opa/pr/us-attorney-announces-federal...

There is surely some GDP gain from not ploughing 250m of taxpayers money into lambo's.

cavisne··on Well Known Short Seller Claims SBF Is a Fraud Weeks Ago
Yep Epstein and him have CIA written all over them.
cavisne··on FTX to file for U.S. bankruptcy, CEO resigns
This guy has major Epstein vibes (minus the girls). comes out of nowhere super politically connected, investing in research, with a pretty dubious origin story of how he got rich.
cavisne··on Meta Is Preparing to Notify Employees of Large-Scale Layoffs This Week
On top of AAPL growing their advertising business at the expense of their competitors is more accurate.
cavisne··on Twitter users jump to Mastodon, but what is it?
He could probably make it interesting though.

At the moment there is a magic clump of such people, large language model experts from big tech who have left because they got sick of not being able to apply the technology.

They are currently floating around in various startups, but we are entering a tough market for VC funding. Twitter can offer hardware, data and a culture of shipping.

cavisne··on Context to Twitter's 2023 advertisers issues
I think this will all work out fine in the end, the unique thing with twitter is the exact people who lead these boycott campaigns... are all completely obsessed with using twitter. The author of this thread is a prime example.

And the ads are placed on the feed not on a piece of content (like the issues youtube was having).

Elon should just deploy a "woke bubble" option where your ad is sandwiched between posts from two liberal elites. The audience would still be broad as just as many people follow these people to laugh at them as to support them.

cavisne··on D-Wave Launches in AWS Marketplace
The actual quantum computers don't live inside AWS datacenters

https://aws.amazon.com/braket/faqs/ (under security)

Most of AWS Braqet is orchestrating emulators (ie fake quantum computers running on EC2).

cavisne··on The Restaurant Industry’s Worst Idea: QR Code Menus
In some countries this is often a menu + a ordering and payment app.

It's very popular to the point that servers actually ask you to use it vs asking them.

In America this wont happen because of the tipping culture, so we get the worst bit (reading a menu on your phone) without the useful bit (reliably entering your order and paying without the check/card/away/back/tip dance).

cavisne··on Alphabet Earnings Report Q3 2022 [pdf]
Waymo has taken a fair bit of external funding. Google could in theory cut them loose which would effectively kill them, but I'm not sure they could just shut it down.
cavisne··on Alphabet Earnings Report Q3 2022 [pdf]
Its not about the inflation rate, its whether it's controlled. The fed reacted slower than expected to inflation, and claimed it would be transitory for a long time.

Hiking is meant to take heat out of the economy, doing so while the government was still pouring covid stimulus money into the economy would've been counterproductive.

Covid stimulus went on too long (later stimulus checks, mortgage forbearance, eviction bans), well after people had returned to their lives. And we are only beginning to see just how much of that money had no productive impact on the economy (PPP fraud, theft of unemployment benefits, scams around fake tests and masks).

Billions of dollars have been spent without contributing to GDP, governments need to cut back fiscal policy to control inflation.

cavisne··on Lawsuit filed against rent-setting software RealPage
When finding a new apartment a few years ago I scraped a few sites. The variance in price is pretty interesting, ie. certain days of the week were better to press "Apply" on the rental form.

There is no strict need for this software to be anti competitive, now that prices are online they can do plenty of experimentation day to day on their own prices.

I also think the claim that they have some secret source of data from negotiated rents is not realistic, large companies don't really negotiate on rent.

However its bad news for the company that the lead developers of their two big software platforms appear to have gone on record in a pretty negative way.

Probably they got to greedy and have exposed themselves to anti trust by commingling data.

cavisne··on Building the Future of TensorFlow
Was honestly expecting this to be a deprecation announcement…

Not because it’s google but because Jax has so much momentum lately.

cavisne··on Nearly Half of San Franciscans Have Been Victims of Theft, New Poll Says
They really don't, and it's important for people to know that or they might be under the illusion it will be fixed at some point.

The people who vote in SF and run the government there are obsessed with punishing some undefined "privileged" set of people who are somehow causing all the issues. Of course they are themselves highly privileged so it's a self hatred.

It will keep getting worse.

cavisne··on Nearly Half of San Franciscans Have Been Victims of Theft, New Poll Says
At this point it's basically the monty python "its just a flesh wound" scene.

Anyone who has visited SF knows exactly whats going on.

Anyone who lives in SF also knows exactly whats going on. They'll just desperately point to some statistic from a tiny town they've never been to that actually measures and enforces the law.

Anything to justify continuing to vote for whatever the media tells them to vote for next.

cavisne··on XCheck at Meta: Why it exists and how it works
The first thing that comes in to mind is the Bezos leaked nudes.

At the time there was a story about the Saudi's being involved and some link to Trump.

Years later it came out that Bezos's investigator knew pretty early on that it was likely the brother of Bezos's girlfriend, however the National Enquirer was already in trouble for allegedly acting as a foreign agent for the Saudi's. By seeding the fake Saudi story they were able to apply huge pressure on the Enquirer.

Maybe something similar is happening here, Meta is under legal pressure somewhere on this topic. It doesn't have to be true, it just has to annoy the wrong politician/judge.

cavisne··on How to succeed at Meta
Maybe I've been in big tech for too long but this actually seems like reasonable advice to me (delivered in a snarky way).

Big tech companies move slow technically, but move fast in organization structure. A "long term" project often means nothing ever gets done, a management chain change happens, and it all goes to nothing.

Metrics are never perfect, but it beats hand wavy claims of success, normally if a change is useful there is some metric that will show it. Honestly, the default "success" in big tech is the scope being reduced so many times that literally nothing happens and the PM's and management treat it like a win.

Finally testing... It's already easy enough to get nothing done in a big tech company but test code can take this to another level. You can join a team, write a big design document about some testing framework, spend 6 months implementing it, then leave the team just in time for the next reinvention of the test framework. And the whole time you were never at risk of deploying anything to production.

cavisne··on Project Starline expands testing through an early access program
For the tech to succeed they need to sell to enterprises, scale manufacturing, and be making the right bet on the future of work

In my opinion google has the wrong instincts on all 3.

This is not really a tool for hybrid work (it’s too expensive to deploy in homes) it’s a tool for communicating between offices.

Google is betting on everyone being back in the office at some point.

cavisne··on Coinbase and Google Cloud
“ developers to instantly and reliably operate Web3-based systems without the need for expensive and complex infrastructure. ”

Ie without worrying about any of that pesky decentralization!

cavisne··on Stateless – Evolving the architecture of Elasticsearch to simplify deployment
What they are really doing is offloading the job of persisting data from ES.

So you wouldn't need to use S3 or some s3 emulator like other comments have suggested.

Give the ES cluster a disk it can write to that is guaranteed to be replicated (ie a RAID cluster) and thats it. The limits of object storage (no appending, no in place editing) tend to make those clusters cheaper so you could also run something like Ceph locally. It's probably going to do a better job of persisting data than ES also.
