I had a think about this and I agree. There’s some tension here - you want breadth, but you don’t have enough time to get good at every language and framework. Maybe the right approach is to have familiar ground in each domain you find yourself. Pick enough languages and frameworks so you have trails in any terrain you want to tread with your work. You don’t need to be an expert in both php and rails, in both Java and C#, or both unity and unreal. But you want enough scope that if you want to throw together a quick and dirty UI prototype, you have familiar tooling you can call your own.

For me, when I want to make a quick UI prototype I reach for JS and Svelte. Because I’m comfortable there, its not worth it to also be an expert at rails, and Php and SwiftUI and C#/WPF. But if the only tool in my toolbox was Rust, or C, or Unity or something, I’d be much worse at prototyping user interfaces. The inverse is also true - if I wanted to write a database but only knew JS, I’d be in for a rough time. You want a home base in each domain.
You are getting downvoted, but I agree with parts of your argument. The part that is perhaps missing is that reversing the microarchitecture or any complex system is generally not an end in itself. It is a prerequisite for more meaningful research. For e.g., building a simulator or finding side-channel vulnerabilities require a good understanding of the u-arch.
My biggest criticism of Wikipedia is that it refuses to publish anything that isn't supported by a dead tree publication, like the ones Elsevier publishes for a fortune.
You could be a prominent, highly respected full professor, but unless your research paper has made it into one of these publications, and actually gone out the door, your research won't be included in Wikipedia. Wikipedia is great for the kind of stuff that used to be published in print encyclopedias, but if you want to find out about cutting edge research, arXiv.org is a better source.
There are many EU directives that are indirectly aimed at limiting how people use energy, for example requiring high thermal insulation windows. Taxing crypto exchange outflows is no different IMO.

> We hope to ultimately build a Slack/Teams alternative designed for rich, asynchronous human interactions that encourage deep work.

All I can say is keep going. I've been feeling the absence of this for a while, and have taken to making occasional videos on Loom to supplement live meetings and Slack messages. But it's a disjointed experience, and Loom is not trying to be a collaboration tool at all. It would be great to have a solution that does the whole thing end-to-end, with a focus on being more async-friendly than Slack.

By the way, I downloaded the PingPong app, and it seems great. Are you selling subscriptions, or just putting the free version out there for now?

Something to understand, for those who might have just seen some youtube videos of him being goofy, is that he's an actor. The guy on camera doing stupid stuff is a stage persona. It's an intentionally cultivated image and media persona to get as many video views as possible.

I sort of see him as one possible aspect of the low/medium budget TV production stuff which is common in his home city, Vancouver BC. People who've met and worked with him in person report that he's a much more normal, calm, rational individual off screen.

I won't judge him for being goofy on camera because it's hard to make a living as a working actor. For every person who gets a job in a vancouver-produced TV drama that might last 2 or 3 seasons, there's dozens more people who are working as restaurant servers while trying to get their big break.

I said that you can't verify the header until you have downloaded the entire block - meaning the time between a false header being submitted and the last transaction in the block being downloaded is time the miner either abandons its work on the last real block and then sits idle or risks hashing a new block prior to verifying the false header. He implied that you can somehow verify using the PoW. I demonstrate that you cannot. I'm not sure how you could have missed it.

They are doing the correct thing then. Prisons, ID, policing NONE of that stuff should ever be in corporate hands. It just stinks of fascism to anyone who really thinks about it for more than a moment.

Apparently an organization called Shadowserver (a nonprofit security organization) claimed that the blog was part of the control system for a botnet, and the domain was transferred out of the registrant's control with no due process. They got it back, but the fact that such a thing is even possible in the first place was infuriating to me. I don't know if this is a decision that the .in TLD makes, to place trust in groups like Shadowserver (one could argue it's India's TLD and their country gets to run it how they want) but I hope to god that these kinds of "no due process" seizures are not possible with other TLDs like .com. and .dev.

Domain names ought to be property, and like any other property should be protected against arbitrary seizure by courts of law. I understand it's important to fight cybercrime and botnets and the like but there's got to be a solution that involves due process.

meowface, most things that you mentioned above cannot be personally verified ( except for the holocaust and COVID 19), so 'believe' is a strong word.
It's simple - I don't trust the media or gov anymore. It's difficult to segregate fact from fiction.

With certain aspects of medicine/health it is relatively easy to verify, if one listens to the renegade doctors, experiment with diets. ( the US dietary guideline pyramid - can actually be inverted, I'm not kidding)

There is a larger point I'm trying to make: it's easy to believe the media, no work is needed, but to investigate take time/effort/perseverance which I have done to the best possible extent.

An interesting (paraphrased) perspective from someone who bought one of Beeple’s $999 pieces and watched the value go up above $80k:

“I’m in an interesting bind. On one hand I can prove ownership to Beeple and claim my physical piece, but on the other hand, I could keep what is essentially the ultimate unopened package.”

I feel like Beeple might lose out on storage fees, but this is a stunning perspective. What if someone could buy a 20 year-old token that allows them to have the piece delivered direct from the artist’s house where it’s been untouched the whole time?

Assuming good faith here, you may need to read the original article again. eBay is delisting 2nd hand copies of the books. That extends far beyond a publisher deciding not to continue printing their books.

Of course, if you believe that copyright should prevent the resale of goods, that's an entirely different story that ignores the current state of affairs in the world and the legislated rights of people in many countries (where there are such laws that prohibit limiting the resale of goods).

One important thing that was not argued well in my opinion is that the Swiss National Bank pegged its Swiss franc to the euro on Sept. 6, 2011. I lost a lot of money on that day, because I had all my net worth in CHF, as I trusted it to keep its value and not be devalued fast.

The good thing that came out from it is that I realized that even Switzerland's central bank cannot be trusted, and moved to Bitcoin. I never looked back.

I've integrated a few laser engravers and laser-cutting CNCs, so let me clear up a couple misconceptions: Lasers typically have a narrow focal length, just like your LED proposal - otherwise they'd damage the optics/mirrors! They're designed to pass a coherent beam of about 10mm diameter through a series of lenses and mirrors. The beam of an engraver might carry 10W of power in that diameter, which is pretty bright, but decent lenses or mirrors with high transmission and reflection won't be damaged. It's safe for both skin and optics until, say, 100mm after it goes through the primary lens. Hopefully at the surface of the thing you're cutting or engraving, it's a spot size of 0.1mm! With 10W of power in that tiny area, even exotic antireflective glass that can transmit 99% of the light will be atomized.

If the thing you're cutting/engraving isn't present, then 100mm past the focal plane, it's back to 10mm diameter, and 100mm after that, it's 20mm, and just continues dissipating. It's really pretty hard to focus it back into a coherent beam sufficiently narrow to damage eyesight (much less skin).

Yes, the CDRH is really concerned about the possibility of a laser system accidentally lasing a blob of metal into a perfect mirror that will send a coherent beam directly into the eye of an operator standing meters away; I've got laser systems with thousands of hours on them etching reflective foil off of plastic and there's no sign of reflections causing damage to the smoked acrylic that's shrouding the operation.

The typical mechanism used to drive laser engravers is more like a HDD actuator that moves the read/write heads - it's called a galvanometer. Basically a mirror on a stick connected to a magnet. A voice coil pulls the magnet +/- 10 degrees or so; They've got sub-millisecond response times so hitting a moving mosquito would be no problem!

I propose that you suck the mosquitoes through an enclosure with something like a box fan or duct booster. Make sure the entrance and exit has to go through a couple right angles so your laser optics are never visible to someone outside the box. Backlight the inside of the box so that instead of AI to see whether the thing in your camera FOV is a mosquito or a songbird really far away, you just zap any black mosquito-sized blobs that pass through.
Can someone remind me why, today, any company would ever choose to IPO instead of direct list?

IPO means paying a ton of money to bankers, as well as leaving tons of money on the table if/when the stock "pops".

Especially now that, since December if I understand correctly, companies can now sell additional shares at the moment of the direct listing, which apparently used to not be allowed.

And then the idea that an IPO comes with guaranteed buyers hardly seems necessary in today's high-frequency high-liquidity age of trading. Plus, surely a ton of employees and investors will want to at least partially cash out from the first millisecond if the price is right, so supply will be there.

I wrote this so I can do regular maintenance reboots on my FreeBSD router(s), without losing the IP assigned with PPPoE, and without losing the internet connection for my house.

Pretty niche, but I can't be the only one stuck with PPPoE who wants to do it a little better.

(I was letting the DSL modem do PPPoE for quite some time, but I wasn't happy with how they handle IPv6, and ended up in bridge mode, so my router has to do PPPoE)
That depends on the electric grid being disconnected so there's 'wasted' renewable capacity that can't be used in other areas currently serviced by coal thermal plants. Otherwise even with transmission loses it'd be better used transferred to one of the other regions.

That also is not burning books. eBay is a private business choosing not to be involved in the sale of something against their policy.

Definitely not; what do they have in common beyond being statically typed and compiled?

Where they differ: memory safety, sum types (don't tell me std::variant is a valid replacement), move semantics, having pointers, classes, GC vs RAII, statement vs expressions... That's a lot of differences.

Check the reference client buglist, they got hit with a slowloris resource exhaustion combo. They fixed the resource exhaustion (kind of), they did not address the slowloris vulnerability. So again, you have no idea what you're talking about. Doubly so if you didn't write the backend of a major mining pool - because you're just running your mouth about code you haven't seen otherwise.
> A major missing detail is accounting for the other phase conductors in the transmission line.

Good point. So for the customary 3-phase power lines the UNC exam is confusing and the given sample solution wrong. In reality you could steal much less than the already ridiculous amount in the exam.

The German railways operate a 1-phase power grid. (After all 3-phase transmission makes only sense if you are able to balance the consumption of the 3 phases at a single place (small area in real life). With relatively few trains using 1 phase at uncoordinated locations that's not the case. And they cannot use the public grid because for historical reasons they operate on a different frequency.

A 1-phase transmission line needs 2 conductors. With my high school physics, I can't tell what that means. Isn't it so that when the max current flows in one direction in one conductor it will flow in the opposite direction in the other one? So what you can steal is determined by d1^2 - d2^2 where dn is your stealing coil's distance from conductor n? Orders of magnitudes worse than in the exam once again.

>Does anyone understand what point is being made here?

A cylindrical barrel is being fit over a fixed centre pin, rather than a pin inserted into a barrel.

Makes sense when you realise that the moving component is inside of a similarly cylindrical bomb casing and that no fancy and complicated sabot and/or rail arrangement are required to keep it aligned and centered with the fixed pin.

Most DC charging plugs work the same way for the same reason.

> The catch is that, whether explicitly or implicitly, you must make assumptions in the first place about the directions of causality among the variables.

That right there is the headline to me.

Compare this with the blurb in the dust jacket of the book:

> "Correlation is not causation." This mantra, espoused by scientists for more than a century, led to a virtual prohibition on causal talk. Today, that taboo is dead. The causal revolution, led by AI researcher Judea Pearl and his colleagues, has cut through years of confusion about the nature of knowledge and established the study of causality at the center of scientific inquiry.

This all but claims that these new causal tools have found a solution to the problem of "correlation is not causation." But they have done no such thing: there is no new technique offered here for establishing causation in any better or easier way than the RCT of yore.

If you get rid of the warning "correlation is not causation" and focus everyone's attention on all the exciting inferences you can make when you assume causation, I'm worried that the end result is a lot of bad science.
