GitHub reverses takedown of reverse-engineered GTA source code
TSMC is currently headquartered on land which is:

* undergoing a drought and they're having to truck in water to sustain their operations.

* claimed by a powerful country different than the one currently controlling it.

Sounds like a lot of risk that they probably would otherwise not want.
Same four* suppliers actually, just about every rechargeable embedded battery is made by Panasonic, Sanyo, LG, or Samsung.

Most common type/size is the 18650, used in everything from drills, powerbanks, to Teslas. Second most common type is the 21700.

A "scientific" test isn't even necessary, just tear down the battery pack, see what cell they put in there, and read the spec sheet. The big 4 battery makers will sell you a whole range of batteries in that size with varying mAh/Amp.

Googling teardowns, I found a Black & Decker 1.5A MAX Lithium simply uses a bunch of Sanyo UR18650W2 (1500mAh rated at 18A) cells, while a teardown of a Dewalt pack shows they used the more expensive LG HB4s (1500mAh rated at 30A).

There literally no reason they can't use the better cells in the Black & Decker, other than they're building it to a cheaper price point. The fact that they're built in the same factory is besides the point.
What I find amusing is that I never noticed the ads on my cheap Roku TVs until they were mentioned on HN. I never spend more than a few seconds on the home screen, and that's the only place they appear.
Business idea: caching layer for kit manufacturing.

You have a warehouse that stores stuff, and sells it to manufacturers when JIT runs into issues.
Are there any active non-Windows ransomware infections going on? I don’t recall seeing any macOS / Linux / Android / iOS attacks.
How big is a GPS tracker? Can I slip one into a dog collar/belt/shoe tread without anyone noticing? Will it still work where there's no cell signal but you still have WiFi?
> Would it be smarter as a murderer-for-hire to ask to be paid in a less-expensive (for now) but growing currency such as Etherium or Litecoin?

No, because the efficient market hypothesis.

If you know that some asset is definitely going to significantly appreciate in value why don't you just buy it and skip out the hitman thing? The answer is that almost noone has any better idea of what the correct price should be than whatever the current price is.
TSMC is planning to spend $12bn in the next decade on the fab they're building in Arizona (which I believe has some level of US government subsidy). I am sure they would be quite happy to get further government $$$ for their operations.

(TSMC also owns WaferTech and their US fab in Washington state).
But did they see this post coming?
You can buy Starlink right now if you live in parts of the northern US or parts of Canada. They're expanding constantly. I've have one for a few months now and love it. Interest was so great they asked the FCC to expand licensing to 5M people. Search "starlink review" on youtube for many examples.

> "Despite the fact that SpaceX has yet to formally advertise this system's services, nearly 700,000 individuals represented in all 50 states signed up over a matter of just days to register their interest in said services at www.starlink.com. To ensure that SpaceX is able to accommodate the apparent demand for its broadband Internet access service, SpaceX Services requests a substantial increase in the number of authorized units."[1]

700k signups is pretty good for no advertising.

Linus Tech Tips review on Starlink: https://www.youtube.com/watch?v=Fh1a2K9ZgNA
Author here. I’m a professional musician of 15 years transitioning into software development.

With this app I aimed to create an intuitive and usable drum sequencer that would run in the browser . I’ve always wanted to be able to program beats longer than 16 notes and see each instrument playing at the same time.

It’s built using React, Redux, and a fabulous web audio library called Tone.js.

This is the capstone to my learning to code which started in sept 2020. I was thrilled to be able to build something that combined my history in drumming and music production.

Happy to answer any questions!

EDIT: Link sharing was not working right but has been resolved. Share your beats! (You will have to re-save to generate a new url)

I'm not sure I'm following exactly what you're working with and what the intention behind it is, so this may be entirely off-base. But the first thing that pops to mind is the idea of finding convex hulls[1]. If you have line segments, then you have endpoints by definition, and if you have a group of points you can find a convex hull. So if you're trying to classify groups of line segments as shapes, some sort of iterative process of trying to match those sets as the convex hull of a shape might work... dunno, not an expert on this, and I may well be misunderstanding what your goal is.

In any case, I would suspect that an answer would be found somewhere in the bowels of graph theory / combinatorics, or maybe topology.

I think this reply is basically saying that if you’re worried about law enforcement tracking you via an airtag, yet you’re already using an Android - or indeed any other phone, then you’re worrying about the wrong thing.
I think they’re also suggesting that an iPhone is slightly better for privacy due to its MAC address randomisation - but I don’t know enough about this and Android equivalent or lack of it to comment.
Not sure why people down vote factual statements if they are wrong and not comment a correction. I can confirm that Canada does have different tax rates across the provinces across all types of taxes: corporate, income, sales, etc. Even at the local level, Canada doesn't have municipality based taxes so to speak but you can certainly find fees charged only in that city which is of course a type of tax. For example, Toronto used to force retailers to charge for plastic bags even though it wasn't collected by the city. This bylaw was removed in 2012.
I found it a bit slow when I used the beta. The search was especially bad since I'm used to ripgrep.
Turns out the right data makes logistic regression go a long long way.
FYI, the author has a huge conflict of interest whenever he writes about cryptocurrency, seeing as he's the founder of Adjoint, Inc, a company which digitizes cash and settlement processes for multinational corporates.

So it's easy to see why he hates a technology that renders his entire company useless.
This type of government/corporate collaboration is similar to how other traditional industries like autos, oil & gas, steel, etc., usually operate. That's because the capital cost of building factories and supply chains exceed the private sector's ability to tolerate the risk of such investments. And a big reason why the risk is so high is because the business is both unpredictable and low margin.

This has never been an issue in the semiconductor industry until now. Demand was always increasing and margins have been high enough to allow them to self-fund. If semiconductor companies now need subsidies to expand then we are probably past the "exponential growth" era of semiconductors. Technological gains will be much slower and much more consistent with traditional industries rather one that what we're use to.
US corporations have recently been given a corporate revenue tax cut, from 35% to 21% (and beyond this they apparently enjoy a bunch of loopholes bringing their taxes much further down). Surely that is more than enough for them to be able to bankroll chip fabrication in the US - individually or together.

Isn't this simply an attempt at "double-dipping"?

"Please subsidize us! The humongous corporate income tax deduction you gave us is not nearly enough!"
Okay I'll ask... Did you at least get their consent before tracking them?
Then why are ransomware operators getting paid in Bitcoin?

It's not impossible to use the regular banking system for crime. But it's a lot harder, and a lot easier to get caught. A cartel in Mexico with an annual income in billions might be able to bribe or threaten the right people, but some techie running a small call center is going to have a harder time.

Have you considered the possibility that your high salary is not entirely due to a shortage of people with the same skill level, but rather because SF/NY companies have too much investor money to spend?

I'm not saying that good software engineers are a commodity, only that SF/NY salaries are too high compared to the rest of the world.

Engineers with 1-2 years of experience in SV can make more than most seniors with 20+ years in Europe. Would you say that's because all these junior engineers in SV are worth more to a company than seniors in Europe?
Porting Linux's eBPF to Windows 10 and Windows Server
Can you elaborate? I know very little about Monero.
It's pretty obvious. Imagine that someone comes to you and shows you a cube. This cube has lightning inside of it, and you can press a button and it creates lightning. This cube can also program software, so if you feed it user stories, it outputs SaaS businesses. You try to understand how this magic lightning works, but to no avail, it's simply too complicated for you to understand.

Your first emotion is most likely fear. Like how the hell does that thing does it, how does it's magic work?

This is how many people see cryptocurrencies. Something "magic" that just somehow is used as money for some people, but it's still just ones-and-zeroes, how does anything make sense?! First reaction is to be careful around it, and try to "protect" yourself from it.

We saw the same thing with the internet initially, until it gradually sucked us all in. We saw the same thing with social media initially, until it gradually sucked most of us in.
Thanks! It's true that on a 2 or 3 call participants P2P almost always ends up having better performance. But the problem comes when you try adding more participants.

The limiting factor is that on a P2P mesh with N participants, each participant sends its stream to all other participants (to N-1 destinations) and receives the stream from all other participants (receives N-1 streams), which incurs on more network and CPU requirements.

When we go above 4 participants the call model changes to Single-Forwarding-Unit (SFU) where there is a central server that dispatches the different streams to each user. That way, each participant would only upload their stream once, and download N-1 streams back. This server may also apply some other optimizations. You can learn more about P2P limitations from this blog post. [1]

That said, as this CoBrowsing experience is not as bandwith intensive as a 30fps high-quality video, we can afford to use P2P with more than 4 participants.

None of this has anything to do with why the iPad and iPhone are not good for desktop style professional apps.

You list a bunch of ‘examples’ - but what are they examples of? Nobody disputes that Apple controls iOS.
The same shortsighted argument could've been done at various times against cryptography, against torrents, against remote access, against the internet, and against using computers (inherently hackable). Now it's crypto payments, and tomorrow it's going to be something else because criminals use technology to scale as much as everyone else.

Crypto networks are especially good at cross-border payments, and they are hard to censor by a state actor. Indeed, these were among the design constraints of Bitcoin. If one wishes to argue that such a technology shouldn't exist, good luck with that; it exists, has legitimate use cases, and banning outright it is shortsighted in the same way opposing cryptography is shortsighted.
FWIW, 'time' isn't circular in Hinduism either, at least not in the way the article makes it out to be. The physical universe has a cycle of creation & destruction, but each cycle is distinct from the other. The general beats of each cycle are largely the same, but the souls move through them in linear fashion. An analogy might be made with a theatrical production: each night set pieces & backgrounds go through a fixed order, and the cast moves through the set according to the script, but the actors in the cast can change over time. In schools of thought such as Saiva Siddhanta, the manifest universe is created with the express objective of providing a platform for souls to move through and work out their issues before achieving enlightenment. Souls that achieve enlightenment don't return to the material world (with some caveats), with the universe resetting on a regular basis for the rest of the souls to have another go at it.

Some schools of thought in Hinduism (Vashishta Advaita, Dwaita (?), Gaudiya) envision a multiverse that resets, but time still moves only in one direction.
Sorry, what's the "danger" here? He's still doing press conferences and the Republican party is still actively cancelling members who dare to disagree with him. Folks on Fox, one of the most mainstream media companies, still refer to him as the president. For being deplatformed, he's sure got helluva platform.

Mars is considered to be the hardest planet to land on in the entire solar system, you have to carry a heatshield or you will burn to a crisp, but it's so thin you still have to land propulsively using rockets. You definitely need to sacrifice less spacecraft mass to land on the moon

Also there is some water on the moon so you can make rocket fuel, though how much exactly remains an open question
I agree with the industry response here. KRACK was the same thing. The author finds a vulnerability that is absolutely valid (no denying here), easy to exploit in a lab but very hard to exploit in practice. Back in the day, we did test our equipment for KRACK. We concluded that someone had to circumvent all our physical security barriers (challenging, but theoretically possible) to get close enough to an AP that would see sensitive stuff, had to know WHEN to do that, or at least plant a device that could easily be noticed, and they would still fail because we didn't have 802.11r enabled on those AP's.

Is it a concern? It depends on what you're doing. It is absolutely a concern if your corporation is handling ultra-sensitive information. However, you should also question your physical barriers in that case and whether you should use Wi-Fi at all for some aspects of your operation. Is it a concern for the vast majority of office workers or someone at home? Probably not; there would be easier ways to find a valid credit card number that don't involve the time and effort for a hacker to travel to your place where they could be discovered. There's no need to replace all your AP's with new hardware, although the Wi-Fi Alliance would love for you to do that.

Does this exploit warrant its own fancy name and domain name? As was the case for KRACK, I don't believe so. That should be reserved for vulnerabilities that have a severe impact AND are extremely trivial to exploit with no proximity requirements. If not, the fancy-name-vulns risk being deprived of their ability to get the attention that is required.
How about if I just don't want Apple collecting data at will or using my device as a private mesh network?
Congrats! This looks very cool at a glance.

I tutored math for extra cash in grad school, and I was almost exclusively hired by well-off local families so that their their high schoolers could improve from an A-minus to an A, ace the AP Test, test into Calculus 2 at UMich, and have a leg up getting into the business school. I loved talking about calculus every day, but it felt like I was participating in a weird arms race between these parents, and upholding a status quo that I really don't agree with.

Tutoring other students in undergrad was much more fun and rewarding -- even though the pay was 1/6 the rate -- because it was paid for by the university and anyone could walk in and get help.

I hope this turns out to be sustainable, as I'd love to give some of my time to it.
True but that also creates vertical integration, which is something that has caused many problems in the past. I'd like to see these huge companies solve their supply chain problems by splitting themselves up, in the process creating the companies they need to supply them, without owning them outright or restricting them from working with others in the market. Basically spin-offs that are designed to be spin-offs from the start.

Since the current stockholders would have shares in existing company and the new entities, they're not being damaged in the process so they shouldn't be opposed unless maximizing vertical integration is their plan for continued wealth growth.
A move towards making sales taxes less transparent in the United States is unlikely, because many U.S. founders associated with the Democratic-Republican party such as James Madison were influenced by the French Physiocratic school economics, which considered broad-based sales taxes to be a quite harmful method of taxation that should never be relied on as a permanent source of revenue.

This opinion is most clearly expressed by Joel Barlow in "Letters Addressed to the Yeomanry of the United States: Showing the Necessity of Confining the Public Revenue to a Fixed Proportion of the Net Produce of the Land; and the Bad Policy and Injustice of Every Species of Indirect Taxation and Commercial Regulation" (1791).

Yes, tax policy compounds the problem; if you have a warehouse of goods, you're already risking that your tangible goods will be damaged by mold, rodents, fire, severe weather, improper employee handling, theft, or changing market conditions. Now on top of that the IRS treats your inventory as if it's an appreciating asset, and Sarbanes Oxley makes you out to be an enron-class criminal if you claim to hold any value there -- because it's not as easy to audit as other financial instruments as stores of value.

We could definitely retool our regulatory policy if we want to improve our posture in the trade conflict.

Mikael at Candela, the maker of C-7, here. This post is inaccurate and frankly makes no sense. First, the waves will never capsize the boat. Due to low cog, it's virtually impossible to do - we've tried. You can manoeuvre just fine at all speeds, but at high speeds it's correct that you might not be able to avoid running over a log or other submerged objects. Same goes for regular planing boats at high speeds. If you hit something, the foil will withstand smaller objects - branches, debris - but is designed to come off should you hit a bigger object, such as a log. While the foil breaks off, the hull will stay intact and avoid damage. Now, on the other hand, if you hit a log with a conventional boat, there's a risk the hull is pierced and the boat sinks. Regarding the "weight ratio": hydrofoil boats are super energy efficient and need very little power at cruise speed compared to a traditional hull, which is why we use them for C-7. At 22 knots, the C-7 uses about 25 hp, which is pretty remarkable for a 25-foot boat. We have a passenger capacity of six persons, but have actually taken off with 10 persons on board - using a motor rated at 65 kW!
