> if you're offering <$10 food items at a mom & pop shop the credit card fees are non-trivial so there probably is a very legitimate incentive to take cash.

Yeah, but not a 10% incentive, especially given that depositing cash isn't free either, for commercial accounts.

> There's also benefits to getting immediate cash that you can put in the bank for expenses at the end of the day vs waiting a day or two for credit card money.

patio11 actually argues that it's the opposite which explains why stores offer you to take out cash along with your purchase when you pay by debit card) in another article at https://www.bitsaboutmoney.com/archive/the-infrastructure-be... - "And so, getting magical paper out of the till and into your wallet without it first visiting the bank saves the retailer money. It can also, potentially, earn the retailer a small amount of float. Cash in its tills is dead money and may not be deposited until e.g. the end of the week or later, but selling that paper to a customer for real money results in it arriving in their bank account faster than physically walking it to the bank."

It might be different for a small mom&pop store that actually deposits their cash every day, of course.
Not exactly something you'd expect a model of this size to solve, Mixtral fails it too (if you switch the names/genders that is, since it's contaminated with a few versions). It does at least indicate that their training data might indeed be as clean as they say.
For what it's worth, I don't know whether we'll ever know all of the Jobs-era skunkworks projects that were shut down before they ever saw the limelight. The lid on the rumors was much tighter back then.

IIUC there is a physical limit from thermodynamics in converting back, based on the temperature. So when efficiencies are quoted, it could be either the proportion of input energy retrieved, or the proportion of the theoretical max efficiency achieved. I'm guessing you're quoting the former?

I had the inverse take. Read Dispossessed and thought the commentary was insightful, so I followed it with LHOD, but I felt like the points it makes about gender roles are blunted by the passage of 55 years, more so than points about capitalism.

I'm an experienced skydiver - one death per year is an insanely low bar for any drop zone. Lodi is notorious for incidents and I would never jump there.

Skydiving seems insanely risky because it's scary but it's statistically not particularly risky [0], especially for conscientious skydivers at well-run drop zones. The calculation on "calculated risk" changes dramatically once you start blowing off safety protocol, which are what keep the sport relatively safe.

I’m just saying that I don’t think the lottery player who got sent fake porn of herself is necessarily a member of the ‘perpetually offended’, to whom you’re ascribing the demand that model outputs be restricted.

I think she’s part of the class of ‘actually offended’. This image wasn’t ‘problematic’, it was potentially actionable.

And when you are a business, actually offending your customers is normally not a good idea.

Striving to create software systems that avoid actually offending people is a good idea, even if it comes at the expense of some other benefits. Whatever ‘performance’ we apparently give up by training systems not to generate nude photographs has to be weighed up against the risk that it might do so at an inopportune moment.

Open weights is one thing, but we don't even have that with OpenAI at least.

Even then, open weights is like me checking in a .exe and acting surprised if people look at me funny.

I'm definitely in the camp where all the artefacts are provided along with fully reproducible build and test environment for anyone who wants to retrace the steps.

Whatever 'open' means, I don't think it is eight shell companies, not even weights provided and closely guarded secrets around how RLHF, alignment and safety testing is carried out.

In fact, you would think that being 'open' about at least alignment and safety testing procedures would be the least one could expect.

I do understand that revealing these things may disclose zero day exploits for bad actors, but on the other hand, being open for inspection is how things get fixed, and I've never been a fan of security through obscurity.

Is swiftUI is still quite a flux state? And not can be done by it?
1. Every software needs resources to be maintained and improved. Those resources finally will need to be paid for by someone.

2. Getting Linux and LibreOffice does not get you a functioning productivity environment. You still need mail, calendars, shared document storage, web conferencing, security etc. There are various levels of usability in those and on basic levels you could get those already 30 years ago mostly. But not on a level, where you could reliably have your workforce be flexibly working from home.

So, let's see how it plays out, but it is not making life easier for the IT admins I guess...
Every time I write a search query like "best tool for X" or "alternative to X", I use Kagi instead of Google. Because Google results for those kind of queries tend to be SEO optimized articles where the first recommended thing is the advert. Or even worse, I get some sort of spam/scam sites that get paid to shill stuff. I think got conditioned with bad Google results to not do it for those kind of queries.

For all other searches, Google seems good enough.

What you pay Stripe is for the combination of interchange fees + Stripe's own service fees. The Stripe service component of the fee would be charged regardless. Whatever markup a merchant makes for Stripe's fees are not recoverable and irrelevant to the comparison.

"One of the greatest concerns is the remote code execution capabilities of the XZ vulnerability. The exploited library potentially allows attackers unauthorized access to affected systems. This can lead to data theft, system manipulation, and insertion of malicious code for Linux and Unix-based companies.

Another significant tactic is the backdoor's ability to manipulate the SSH authentication processes. SSH, or Secure Shell, is a vital service used for secure communication and management of systems. Compromising it could result in a breakdown of the integrity and security of the entire system. An attacker could potentially gain extensive control over a system, remotely execute commands, and even move laterally across connected systems and networks.

This backdoor is particularly dangerous because of its subtle nature. It only activates under specific conditions, making it difficult to detect and likely unnoticed."

Seeking a Partner for Senior Level Data Science Mock Interviews
I am in the process of preparing for senior-level data science interviews and I'm looking to partner with someone who can conduct a thorough mock interview of me. I'm aiming to simulate the real interview environment as closely as possible, with a focus on both technical expertise and behavioral skills.

What I'm looking for:
Experience: Ideally, you've conducted or been part of real data science interviews, especially at the senior level.
Technical Proficiency: Ability to craft and assess through technical questions typically encountered in data science roles.
Behavioral Insight: Skilled at behavioral interview questions and can provide feedback on how to best present my experience and problem-solving approach.
Honest Feedback: I'm not just looking for a pat on the back. I want to know exactly what you think about my responses, where I excel, and where I could improve. Think of it as if I were applying to your company – how would you grade my performance?

What I offer:
Compensation: I am willing to pay for your time and expertise. Please let me know your rates when you contact me.
Commitment: I am serious about improving and will value the time you put into this mock interview.
Flexibility: We can schedule the mock interview at a time that is convenient for you.
Reciprocity: I would be happy to conduct a mock interview of you in return. We can learn from each other and improve together.

I'm looking forward to connecting with someone who can help me take my interview skills to the next level.

Tiptree was one of the greats.

Maybe writers can't help themselves, but editors should know better.)
While I work for msft, I'm all for open source, even more in this space - consumer and office apps - however, my government has tried this and rolled it back a while later in some branches, while others just suffer with it.

Office is much superior to any open source and even paid alternatives, and we must remember that most people using the software don't have a degree in CS.

I wouldn't be surprised if we see the reverse news a few years later.
The density of air at 20ºC (293ºK) is 1.204kg/m^3. At -10ºC (263ºK) its density is 1.341kg/m^3, or 11% denser. For a Model 3 moving at 100kph, about half of its power is used to overcome air drag and half is used to overcome rolling resistance. Air drag is 1/2 * density * velocity^2 * coefficient of drag * area, so an 11% increase in density means an 11% increase in drag, so a ≈5.5% decrease in range. That's significantly less than typical cold weather range loss.

Most of the range loss comes from climate control. In a combustion car, the majority of the energy in the gasoline is turned into heat. In cold weather, you just dump some of this heat into the cabin to keep it warm. An EV's efficiency is a disadvantage in this case, as it needs to use energy from the battery to heat up the cabin.
It's possible to make training pipelines reproducible and deterministic using random seeds. There's support for this in PyTorch, Jax, etc. And it can be useful to do so for debugging. You can make it configurable with a flag

By comparison, Stripe charges 0.8% + $0.00 for ACH, which includes any costs they might be paying to the bank, so the upper bound on the cost of their services is 0.8%. 4.4% - 0.8% is 3.6%.

Identify a payment processor that a small business making e.g. $60,000/year in $20 credit card transactions can use that would charge lower fees, if you can.

It was common during the dot-com days. I interviewed with the "VP" who asked me to draw an architecture diagram of a recent system I worked on. He said that looked pretty cool, asked some basic questions. Next day I had a job offer at a 20% raise. No take home, no additional interviews, no white board coding, no written application. Most interviews were like that actually, up until 2010 or so. I remember being shocked by my first white board coding interview.
The other issue is people rent cars where they do not live and are unfamiliar.

No one wants to hunt for a charging station when they need to get to a business meeting on time or enjoy their vacation.

It is also a change in consumer behavior. EV owners just aren’t that big a percentage of the total market, and ICE users aren’t going to learn EV on a business trip to unfamiliar territory.

Money is not dirty, but money corrupts everything it touches [1]. Doesn't matter if that's healthcare, internet, art or computer games, having money as a part of equation twists incentives and changes the overall picture into a darker one. It is (obviously) necessary for survival, and so it's not bad per se, but there's nothing wrong with longing for money-less interaction.

Show HN: Command Line Data Aggregation Tool for LLM Ingestion
This is a tool I created for my own use and I use it more and more as context windows get larger.

It tries to be a quick CLI that accepts one value and determines if it is a Github Repo, GH PR or GH issue URL, Arxiv or Sci-hub paper, or web documentation or Youtube URL and returns that respective file, repo, transcript or page data flattened into one text file to the clipboard for quick pasting into an LLM for ingestion. It creates a low token version of the output file and a token count to the console.

Lately with Claude Opus I have been able to quickly pass quite a large amount of information in one "shoot from the hip" prompt and ask questions like, "Compare these two repos, use them as a reference and build this new thing I just thought of and use this Arxiv paper and library documentation as a guide. Read it back to me before writing code, think step by step, here's a tip, etc" with all of the effort involved in a few cut and pastes of URLS and one barely coherent run-on sentence. The results have positive.

It has an MIT license for free use.

I would greatly appreciate any critical feedback, suggestions or PRs.
There's a bunch of parts of CarPlay which assume you can use Siri.

Probably. HTTP/2 is good for streaming, and even that is being replaced by newer protocols.

For normal asset serving the only advantage is more assets can be loaded in parallel since HTTP/1 is limited on connections per domain. CDNs on different domains usually prevent this from being an issue.

In theory you could serve unbundled JS assets via HTTP/2, but I have never seen it in production. Likely because you still need a compilation step most of the time.
