Just to be pedantic (I think it's ok given the venue...)

- All an isolation transformer (which is an external component you have to supply; it's never part of the radio) does is make the mains AC voltage inside the radio "float" in contrast with the voltage coming from the wall outlet (which is of course referenced to the actual ground outside your house). This makes things a little safer because if the chassis becomes live for any reason then there won't be a potential difference between the chassis and the ground that you're standing on, meaning you won't suddenly find yourself forming part of the circuit if you touch the chassis. In these old radios it's super easy for the chassis to become live so this is a good precaution.

- Isolation transformers do nothing for safety concerning the dangerously high DC voltages which the tubes run on. In the amp itself, the AC voltage comes in, hits a power transformer inside the amp (to get nice high voltages for the tubes), then is rectified into DC, then goes into the circuit to drive the tube plates and do all the other stuff it has to do. You can still get an almighty and quite easily fatal zap if your body provides a path between high DC voltage and the chassis (which is also the DC ground). Hence the rule, only work with one hand in a powered-on amp, because at least that way if you touch something then 350V of DC can't travel up one hand, through your heart, and back out the other arm.

- The final thing you might be referring to ("some older tube radios...") around cost savings is the archaic practice of skipping the power transformer entirely and connecting the wall AC voltage directly to the rectifier. This requires various compromises in the circuit (the DC voltage produced is quite low) and you _have_ to connect these with an isolation transformer or you're really asking for trouble - the chassis is all but guaranteed to be live. The original makers in the '40s and '50s, at least keen to be seen to try to avoid killing their customers, "solved" the problem by using plastic control knobs.

This is why I don’t understand why governments seem to be against cryptocurrencies in general. And as for consumers and privacy: check the work being done with zero-knowledge proofs and stablecoins, where everything is encrypted except to the IRS or whoever should have be able to view transactions. To my knowledge this work is also attempting to replicate cash by not divulging anything under a certain threshold per day.

Besides this, there is no moral prohibition against working multiple jobs in most other fields. Would anybody question the ethics of me working a dev job but also picking up shifts at a local cafe or restaurant? What if I have a side project?

I knew plenty of kids whose parents worked multiple jobs growing up. The fact that those jobs were shitty, doesn't change the ethics of it. Unless you're violating a non-compete, it's not anybody's business what you do with your free time.

In reality, you are basically relying on the fact that no one can tell when you open your laptop whether you check personal email or work email etc. But legislation wise you very well might be in breach of visitor conditions. And if you stay long enough, taxes might kick in.

Canada is a notable exemption because IRCC issued a note on What kind of activities are not considered to be “work”?:

However, unless the relevant immigrant authority or legislation did this , the law still applies.

Private blockchain is a term that refers to blockchain tech that does not divulge balances and transaction history without being a signing party to that transaction or without a delegated 'view' key created by the keyholder for the purposes of the audit. It's a confusing term which should have a better name, I agree.

For an example, most cryptonote networks function this way unless they have explicitly damaged or disabled the functions responsible, like in the case of Electroneum.
The fact that people think that they should have any inherent trust of anything you see or hear (especially online) in the first place is a severe negative. Misinformation has always existed and always will exist, the solution is education and not knee-capping development. This same attitude would've made the internet a far less open place than it has been if it had been applied to it at its start.

I've done tuition reimbursement programs at two jobs (One for bachelors, one for Masters).

The businesses have two benefits to offering these programs:

1) The amount paid is a benefit to the employee but is not subject to payroll taxes.

2) The amount is also qualified as a business expense and can be calculated as such for tax purposes.

So companies have serious tax benefits from offering these programs and generally end up being no-cost due to offsetting tax burden. Even if an employee leaves after earning their degree (mine have always had a 12-month payback period) the company still comes out on top.

The antidote for all who gain information via the Internet is to develop their common sense and critical thinking skills. We must know what to question and then, how to pull answers to form our judgements and our resulting actions. These skills need to be core to all education curriculum.

This is most critical for judgements that lead to consequential decisions and actions. Whether you love someone or hate them, those feelings lead to bad outcomes if not based on correct information and reasoning.

Most reverbs these days are convolutional. I looked at those too! But they require an expensive FFT (usually run in a thread), and the quality sounded "too good" for the audio target I wanted to hit.

After trying a lot of stuff, my main primitive ended up being a delay line hooked up to a low-pass. The output sample is a delay line going through a low-pass. That output is mixed with the incoming sample, and shoved back into the delay. Effectively, this makes a comb filter. I run eight of these in parallel at slightly different delay lengths to comb different frequencies. I was trying to shoot for "digital blur" that had a bit of crunch and aliasing that I wanted, while still sounding like a reverb.

And the track was done by Jake Kaufmann, our composer at Yacht Club Games! I can't take any credit for it.
Great share. I bought this exact radio from a car boot sale for 5GBP back in the mid '90s and it's served me well ever since - until last year when my wife's cat knocked it off the shelf.

This wouldn't surprise me. I haven't listened to the interviews myself, but a lot of people here seem to base their claims on having read secondary sources, not primary sources. In other words, their view of reality is based on how a journalist decided to summarize a conversation that is often multiple hours long. I'm not sure this constitutes a strong enough chain of evidence to diagnose someone with a mental illness.

For what it's worth, these questions have been asked in the context of women/men and sexual conduct. The pendulum swung from "women are ridiculed for being victims" to "men can't be victims and women are always victims". Research is now coming out that a lot of male victims go unnoticed and quite a few women are misusing the status quo. Now the pendulum threatens to swing back to "women are ridiculed" again.

The question itself only matters if no method exists where the pendulum can be dampened more quickly. Given history, there is reason to believe such a method exists.
I agree with you. Rule of law should be upheld, and laws should be objective.

For instance, taxes for minority X will be Y% smaller for the next Z decades.

This is why I don't like where companies are currently going - arbitrary enforcement.

Why not make the laws or rules clear? Because it affords them some level of plausible deniability to push agendae.

There is a top-level comment higher up that lists the individual features. One is notably absent from AA's internal systems: checking that FA schedules are consistent with the regulations governing how much they can work. But the crux of it is that is takes the FA's AA credentials, collects their personal data from disparate internal AA systems, and displays it in a sane way to the FA. And presumably at least a couple of the features (like the legality checker) are sugar on top.

I would not underestimate how terrible internal legacy systems at a company like AA could be. It seems completely reasonable to me that this app could save FAs an hour a day or more. And if they're like pilots (who are typically only paid on time from wheels up to touchdown) that is likely an unpaid hour.

I'd echo a lot of these. You have to basically learn the skills of a modern machinist, including learning the quirks of the materials/machinery/environmental conditions. You can easily have something complex print for 20 hours, just to have it go off-the-rails at hour 21 and wreck the entire piece. It sounds like a dot-matrix printer running constantly for hours, the smell can be overpowering without some sort of air filtration, and the amount of finishing work that has to be done if you want something professional-looking cannot be overstated. At the end of my ownership, I realized that I simply did not need that many little plastic things that take hours to print and potentially hours to design if nobody else has created the exact same thing and shared it.
Outside of VC pump and dump markets, business owners are incentivized to increase net income = revenue - expenses for their own utility and because they have competitors who are working to lure their customers by offering lowering prices.

It is possible that in an explosive growth business area with little to zero marginal costs, focusing solely on revenue and ignoring costs in the short term makes sense, but it is not sustainable. Even then, there is never a blank check for labor costs so someone somewhere will notice a number being too high.
This can't be true.

I understand concerns about how this could be used for unethical purposes, but the Dallas mass shooter case doesn't seem morally ambiguous at all. Lethal force seemed completely appropriate considering the shooter was deliberately targeting officers and was ex-military. By all appearances, this tactic saved lives, and I wouldn't choose this as my example of "concerning misuse". More generally, I don't understand the desire to litigate the rights of an unambiguous, active mass murderer. Dealing with active mass murderers is messy business, and I don't think it's realistic to capture everyone alive--or rather, the costs of doing so are typically innocent human lives, and that's not a cost I'm willing to pay. If a mass murderer is killed and innocent lives are saved, that seems like an unmitigated victory--I don't reserve any tears for unambiguous (racist) terrorists.

I'll take Dallas over Uvalde every single time.

If a store makes daily deposits and those serial numbers are scanned, you can narrow down the transaction to a day. Security footage will show the transaction happening. It's a bit of work, but if that happens to you twice there aren't too many people who visited the same two stores those two days. They now know what you look like and can find your other movements across other security cameras. Bingo, you were tracked via your cash.

Unless you're also an expert at disguise and also avoiding security cameras to and from the stores. Every time you buy something.

> People said you can’t write a financial trading system in a garbage collected language

People have been writing HFT systems in GC languages (Java, OCaml) for a while, and as you mentioned, you need to know when to pause/unpause/prevent collection in the critical section.

This [1] is an excerpt from a talk with Dave Lauer [1], who has done it in Java - it took his system ~40 μs from receiving data to producing market order, and he explains in great detail what amount of work the system had to do. And this was >10 years ago.

This isn't really necessary. "Remove your HDD" is outdated advice.

Any modern SSD can/will leverage cryptographic erasure to render any data unreadable. [1]

Since OP is talking about Apple systems, Mac computers with the T2 chip or newer (which includes all Apple Silicon Macs), full disk encryption is automatic even with FileVault turned off. [2]

Basically, when you erase a drive on a modern Mac, the encryption key is changed, so prior data is not recoverable in the same way that an unencrypted HDD will leave magnetic traces of readable previous data.

But again I am not sure who you are trying to convince here. I have already provided plenty of examples of what I think is use cases both from business to infrastructure to societally. I never said just believe it and I am not sure why that straw man is being thrown in there.

It's always the same discussion though. People who say they want use cases aren't really interested in them. It's a weird phenomena to me but each to their own.

You are more than welcome to think there isn't a reason to think it's going to work out and then you act accordingly to that belief. I see it differently I do see the need and act accordingly.

It's all good.

Yes.

It's frankly absurd that someone can live within the US as a "citizen" without getting have meaningful representation.
So the person who claims to care about his own community doesn’t put his money where his mouth is, but gets to joke about a marginalised minority who in their overwhelmingly majority support racial equality (because they themselves are an oppressed minority and overwhelmingly liberal) in the name of defending his community (instead of attacking those who actually do the violence), and that is unrelated to his actions and behaviour because … ?
