joncrocks··on Getting fitter can reduce prostate cancer risk by 35%, study finds
It's used as a proxy for overall strength, as it's very easy to measure in a clinical setting and there is a good amount of data floating about with it.

A bit like BMI, it could be useful for looking at in overall populations even if there are pockets where it doesn't measure overall strength in an accurate manner.

It's not saying if you train your grip strength you will live longer, but _generally_ those that live longer have greater grip strength than those that don't.

But if they want to buy Bitcoin with them there needs to be someone on the other side of the transaction.
joncrocks··on Ask HN: Are height adjustable desks worth it?
The important thing to bear in mind here is that wobble is relative, i.e. One persons `wobbly` is another persons' `stable`.
joncrocks··on Ask HN: Are height adjustable desks worth it?
I would focus on Reddit, from my research a couple of years ago BTOD sold their own desks and so had a reputation for being biased.
joncrocks··on Many AI safety orgs have tried to criminalize currently-existing open-source AI
If you make the bar too low, then it will be widely exploited. Also harder to enforce, e.g. how closely are you going to monitor them? The more people, the more onerous. Also, can you un-Citizen someone if they break the deal?

Too high and you end up with more experts who then decide "actually it's more beneficial to use my new skills for AI research"

Tricky to get right.

This could have a counter-intuitive impact.

Incentivizing people to become AI experts as a means to US citizenship.

joncrocks··on How to Work Effectively with Someone You Don't Like
Generally best to avoid talking about the specifics of the actual acts when in polite company.

Sex, Politics, Religion were the traditional ones to avoid. I'd also add 'childcare/how to raise children' as another one that can easily escalate/some people have very strong opinions on.

joncrocks··on An update on salary transparency in job posts
The issue is that if you're currently making $200K, it's hard to tell where they might think you might sit in that scale up-front.

It's a bit like saying "Employee - $10K-$10M p/a" - It's not very useful in a job posting, as you might reasonably assume someone being paid the top salary is not actually doing the same role as at the bottom range.

joncrocks··on How a 'Refund Fraud' Gang Stole $700k from Amazon
There are already Amazon lockers (in some places). But it's an option rather than mandated.
joncrocks··on How a 'Refund Fraud' Gang Stole $700k from Amazon
`Getting a signature` is very 1900s. I'd expect to see more like what Amazon do for various high-value packages (maybe even high-fraud), you are given a code which has to be verified by the delivery driver before they will give you the code.

As you say, makes delivery more expensive, as the drivers can no longer just leave packages and makes the interaction longer (+ more redelivery required).

joncrocks··on How to Not Get Screwed over as a Software Engineer [video]
Not a bad investment per-se, but regarding "there is a clear mismatch between how founders and employees value equity" - The founders have more control, and therefore their equity is worth more.

e.g. Founders raise, selling off some of their shares as part of the raise. Everyone else has an illiquid asset, Founders can negotiate a payout.

The major shareholders can authorise issuance of new shares, different classes of shares, issue new shares with anti-dilution clauses. You're correct though, it's easier to value shares with a secondary market.

There are lots of schemes that an unscrupulous founder has at their disposal, so one has to be their own advocate and value their shares appropriately.

joncrocks··on How to Not Get Screwed over as a Software Engineer [video]
The mismatch is not necessarily down to a pure % game, it's related to who's in the room when decisions are made.

The founders are the ones that will be in the room when things like share dilution etc. are discussed. The employees (likely) will not.

The people in the room decide:

a) Who can cash out when b) Who gets diluted and by how much

If you're not in the room, you get no say.

joncrocks··on Scarlett Johansson hits AI app with legal action for cloning her voice in an ad
I've seen it asserted a lot, but I'm not clear on the exact mechanism in play here.

Is it copyright?

Is it some protected legal mechanism encoded in law, or is it agreement(s) between parties (Broadcasters/TV/Film producers)?

Is it only in play if you explicitly say it's a particular person? Can you use an impersonator to voice over something without referencing the person in question/give no grounds to suggest it's a particular person? What if you hire a good lookalike? A soundalike?

joncrocks··on Bank financing and bad urban planning make the retail apocalypse worse
Not necessarily from the perspective of the bank, but the borrower/owner, I've heard of the concept of `prevailing market rent` to be a driver of this.

If I rent out a space to A, they may have clauses that reference the rent/average rent for the building vs. their space. So it might be preferential for me to wait to fill a space at a higher price, financially.

In addition, renting out at a lower rate may end up turning up in surveys of rent in the area, leading to a lower average, meaning that future renters of space that is currently rented will try and negotiate downwards in the future.

joncrocks··on Meta is banning people from advertising after running ads for Python and Pandas
Person, group or Country. e.g. Iran.

Yes, you're meant to do KYC checks, but also be on the look out for things that your non-sanctioned customers might be doing (post KYC checks) that involves interacting with Sanctioned entities.

Hence lots of pattern matching on names of sanctioned countries/organisations/people.

joncrocks··on Realtors Face an Antitrust Reckoning
The difference being there aren't 'buying' and 'selling' real estate agents in the UK, just ones representing the sellers. A buyer just approaches a bunch of agents asking what is on their books (or looks on RightMove).

And 6%? Try ~1.5%

joncrocks··on Detroit wants to be the first big American city to tax land value
Often the market isn't for land, but for land + property. It might help, but overall there is more room for subjectivity/untethered valuations.
joncrocks··on Call to shut down Bristol schools’ use of app to ‘monitor’ pupils and families
I don't think it's just the UK.

I think the issue is that it's very hard to have open discussions about accepting that certain events are unavoidable and preferable to the second order impacts of trying to 'solve the problem'.

It's hard to talk about at least in part that 'the problem' in these situations tends to be a terrible event that can be avoided, but only avoided by doing lots of lots of 'ever so slightly terrible' things. And so it takes a toll on the soul to look at the balance and say that we should live with 'the problem'.

joncrocks··on Airlines make more money from mileage programs than from flying planes
Something that is non-obvious in this space is that some of this can be down to tax treatments and asset depreciation.

In a nutshell, when you buy an asset you can depreciate the value of the asset over the working life of the asset and in many tax jurisdictions (my knowledge/experience comes from the UK and US asset financing industry) offset that depreciated amount against profits, in the year the asset depreciates.

This means that you can essentially offset capital expenditure against tax, which is good business.

But if you don't make enough profit through the use of the asset at the right time, you end up losing the benefit.

But there exist large companies that make lots of profit, such that they can always offset the depreciation. And so _they_ can buy the asset, use the depreciation against their profits and then lease the asset to you. They might even be able to do this at a rate that ends up _being cheaper than you actually owning the asset_, depending on circumstances.

joncrocks··on Vitalik Buterin reveals X account hack was caused by SIM-swap attack
You have to sign a transaction, but I _think_ the details of transactions can be obscure enough to not be clear what you're authorizing. Accidentally authorizing the transfer of tokens/NFTs, which are then drained.

joncrocks··on Knightmare: A DevOps Cautionary Tale (2014)
I think attributing blame to a single place can be difficult in complex situations.

It's a set of failures in a system that all had to happen for the failure to occur.

joncrocks··on Knightmare: A DevOps Cautionary Tale (2014)
It depends on the business. It's not uncommon for clients to execute against different institutions' systems, and they can/would re-route flow to someone else if you're down.

Think less "buying a car" and more "buying a pint of milk". If you're buying a car and the store is closed, you might come back the next day. If you're buying milk you will just go to the store down the street.
