ridaj··on Toll signs on 101 report your transponder setting
Why bother! In 10 years in California I have never seen anyone get pulled over for carpool lane violations, but pretty much every time I'm on the road, I witness one.
ridaj··on SATCOM terminals under attack in Europe: a plausible analysis
Would Russia (assuming it's the source of this attack) have suffered collateral damage / friendly fire on its own satellite terminals?

Instead of Google trends, it would be interesting to see how this shows up in geolocation datasets

Maybe give safe harbor to ransomware operators who target Russia in the same way that Russia gives safe harbor to ransomware operators as long as they don't operate domestically https://krebsonsecurity.com/2021/05/try-this-one-weird-trick...

Yes I think that's the idea and the reason why it's taking a while to set up. Maybe they'll take bitcoin? It will be a test of whether this can really be a backup form of payment against the will of states.
ridaj··on The fastest GIF does not exist
The internet in all its duct tape glory.

Prime example of trade-off between cleanliness of implementation and backwards compatibility. As much as I like a pristine, pure spec, the market winners are clear. It pays to keep product debt around.

ridaj··on Don’t point out something wrong immediately
Yes. My tips for this

* Say yes first. Acknowledge everything and say what you agree with.

* Use the phrase "tell me more." Use this to get context in a nonconfrontational way (as opposed to "why" which can get people in defensive mode).

* Avoid using "but". People don't like to hear it and it makes them forget the past before it. Everytime you want to use but, see if you can use "and" or "at the same time", or nothing, and almost always the result is better.

ridaj··on The EARN IT act is back, and it’s more dangerous than ever
> There’s no regulation for what happens when Google or Facebook or whatever deletes or blocks an account and provides no support.

Yes there is, per the trade regulations you're entitled to a refund

Wait

I'm only partly sarcastic. If you think you're entitled to anything provided as a free service then the problem starts there. Do I miss the days when ISPs provided email as part of your subscription? Then made you pay for anything over 100 Mb? Then held your email address hostage if you wanted to switch providers? Hell no. But I also don't think government should force anyone to provide services to me for free.

Edit: downvotes without replies do not help me understand where this feeling of entitlement to a free service comes from; insight would be appreciated.

ridaj··on Two weeks later David Bennett is alive, his pig’s heart beating soundly
I see many answers arguing that doctors treat everyone the same regardless of their criminal past. That's ethically right, and the victim's family doesn't have to like it either. PETA doesn't have to like it either. My grandmother doesn't have to like it either. Maybe the victim's family would've been happy that he got the transplant if that had caused him to die; maybe PETA would be happy if pigs got transplants from humans. Thankfully it doesn't really matter what the victim's family or PETA thinks of it.
ridaj··on PRQL – A proposal for a better SQL
I wasn't thinking it'd be useful, but more that it's good to remain as free as possible from any assumptions about the schema of the data. I often work with tables that have unusually large schemas (> 100MB) and have seen some products' performance severely degrade as a function of schema complexity.

(But otherwise +1 to schema awareness during authoring.)

ridaj··on PRQL – A proposal for a better SQL
Very cool

Design goal question - is the goal to have a language that blindly compiles to SQL, or will compilation require data schema knowledge?

Suggestion: where possible stick to the well established SQL keywords (prefer "group by" to "aggregate by")

ridaj··on Ask HN: Am I being instructed to do something illegal? (DEI hiring practices)
Lack of knowledge and humility? People look at some of the top companies, lionized as they are for their exclusive hiring process, and don't see themselves as belonging there. All the more so as they don't know anybody there. Meanwhile Jo big-school dude knows, hey my buddy went in and I know based on four years as roommates that I'm smarter than he is, it can't be that hard.
ridaj··on Ask HN: Am I being instructed to do something illegal? (DEI hiring practices)
Not true when the problem is outreach, eg companies that rely too much on existing employees' alumni and social networks to recruit. I know of some people from historically underrepresented backgrounds who'd never have been hired where they are now without active outreach on the recruiters' part, and they were definitely in the top decile
ridaj··on Police in tiny Alabama town suck drivers into legal ‘black hole’
Earmarking revenue just gets worked around. If an agency's budget is $100M from the general operating budget, and $20M earmarked revenue suddenly comes in to that agency, their share of the general operating budget will simply be reduced to $80M.

It's the same reason why lottery revenue or (in California) bond approval propositions are typically earmarked for "noble causes" (schools, firefighters, parks...). It's a cheap promise to make, and the share of general operating revenue allocated to these departments can quietly decrease as lottery or bond financing replaces it, completely working around the spirit of the earmarking.

It sounds trivial to say but control of budgeting decisions is obtained through control of budgeting decisions; earmarking constraints are just accounting games to make spending more palatable to taxpayers.

ridaj··on Union Pacific Addresses LA Cargo Thefts; Problem Requires Collective Effort
Right. In other words the amount of vulnerable wait time is a direct consequence of wanting to fit ever increasing amounts of cargo on fixed infrastructure.

How do truck shippers protect their wares? 1 driver per truck with eyes on the load all the way through. If they have to take a nap, it's in the truck...

How do valuables travel? In armored cars with armed personnel.

The train company isn't entitled to its business model of very long trains with loose security.

ridaj··on Union Pacific Addresses LA Cargo Thefts; Problem Requires Collective Effort
We already all pay for theft via the embedded insurance premiums in shipping costs.
ridaj··on Union Pacific Addresses LA Cargo Thefts; Problem Requires Collective Effort
Or just keep trains moving. I'm shocked that US freight trains are left parked for so long in areas known to be theft-prone with poor fencing. I don't think these kinds of thieves would risk their lives going after a train running full speed.
ridaj··on Union Pacific Addresses LA Cargo Thefts; Problem Requires Collective Effort
I think it's a very good point but you also aren't going to convince a lot of people without offering concrete solutions to the immediate issue. What are they, in your opinion? I personally think if the company kept its trains moving and/or had better fences, it might prevent the thefts in the first place. But if your idea is let's not prosecute theft and focus on reducing economic inequalities, I'm not sure I buy it!
ridaj··on Union Pacific Addresses LA Cargo Thefts; Problem Requires Collective Effort
I think the point was that the number of thefts made outside the prison by people who are in the prison is necessarily zero, unless they escaped. Do you need data to be convinced of this?
ridaj··on Union Pacific Addresses LA Cargo Thefts; Problem Requires Collective Effort
Prevent the theft, don't just deter it through legal consequences. Increase perimeter security (barbed wire, electrical fence) so that it's harder to get onto the rails in the first place. Keep trains moving - don't park them for hours in dense metro areas with poor perimeter security. Get better locks.

Or, partner with Mark Rober to create a giant train-car-sized glitter bomb that will douse thieves in glitter and fart spray when entered.

ridaj··on 29-year-old Conway conjecture settled

ridaj··on I think I know why you can't hire engineers right now
I tend to think it's even more true for smaller companies that do not have the margin for too many mistakes. FAANG do not have an all-A cast. They have enough buffer to weather the odd mishire; and they also have enough projects going on that they can find better projects for people based on their strengths. At a small company on the other hand, the wrong hire can be existentially problematic for the business.

https://en.wikipedia.org/wiki/Signal_velocity - my understanding is that the speed is driven by interactions between the trace and its surrounding material, which creates capacitance and inductance along the path
ridaj··on I think I know why you can't hire engineers right now
> Depends on how you define works. It does effectively filter the people that can't code, but it also filters a lot of people that can code and just can't or don't care to do it under time or environment pressure.

It is much more important for a company to filter out likely low performers than it is to avoid filtering out likely high performers, because the costs of hiring an incompetent person are enormous. Not only do they not produce as much, they eat up others' bandwidth by asking too many questions, implementing super buggy code, or not communicating effectively. They make other people on the team feel like they're not pulling their weight. They're a pain to fire depending on company culture and laws.

This process is designed to overfilter and maintain an A-player roster as much as possible, vs putting butts in seats. It's hard to tell whether the pool is exhausted here - by some indications, there's a lot of attrition but also a lot of hiring...

ridaj··on Welcome to Waifu Labs v2: How Do AIs Create?
Fascinating... Thanks for sharing

A couple questions:

1) I didn't really understand how you went about identifying what vectors of the latent space stand for various things, like pose or color. Did you train one of the AIs to that effect, or did you manually inspect a bunch of vectors, twiddling through them one by one, did to the outcome?

2) If one were to train an AI to the same level using commodity cloud services, what's the order of magnitude cost that you would pay for the training? More like $100, $1,000, $10,000 or $100,000?

ridaj··on CSS Gradients that avoid the “gray dead zone”
If we're going to think about gradients at that level, we should also think about perceptual nonlinearities that create all kinds of distracting visual artifacts... See e.g. https://news.ycombinator.com/item?id=20754364
