Technically, yes, "resistance causes the heat" - but why? Well - because in a CPU, voltages are being manipulated.

Those voltages represent binary values. Usually a positive voltage is designated as a binary "1" and a zero voltage as a binary "0". Putting a "1" into a register (or whatever) is easy - just add the appropriate voltage. But how do you change that "1" into a "0"?

You do so by "grounding" the circuit - that is, a circuit is made where the voltage level representing the "1" is connected to the reference voltage level that represents "0". Since that voltage level is "0 volts" (usually - but not always - but it is usually lower than the voltage level representing "1"); that change in voltage happens to occur across a conductor, and that conductor has some resistance, and that ultimately is what generates the heat.

ASIDE: It is possible to reverse all of this - that is, use a negative or zero voltage to represent a "1" and a positive voltage to represent a "0", and so on - I'm not sure, though, that this is done in common practice, but I am certain it has been done somewhere at least once.

So - what does that mean? Well - it means that in a CPU, just by the fact that it is manipulating voltages that represent the binary symbols "1" and "0" - it is going to end up generating some amount of heat. The fasting these changes occur, the more heat that is output. The larger the voltages involved, the more heat is output (note how this explains why, as CPUs have gotten faster, their operating voltages have become lower).

How do you combat this? Well - it ain't easy - but what if you could, instead of grounding a voltage representing a "1" to make it a "0" - you instead used it elsewhere (in some manner) to generate a "1". That is, instead of wasting that voltage and energy as heat due to resistance, you used it instead to perform the opposite function elsewhere in the CPU?

Well - you can - though it ain't easy from what I understand. It's called:

From a problem solution perspective.

Your "why" section does not actually describe "why". Its more listing reason why you think this is good. I was hoping to see more of "Why" your own private cloud is a good idea. You are describing the solution not the problem. Hope that is helpful in some way :)
Using yarn, without hooks, and giving Google even more data.
Agree. I’ve spent a fair amount of time there the last couple of weeks. It’s full of tourists (both from outside Helsinki and outside of Finland) gawking around and taking photos and selfies. It’s noisy as there is no protocol for that as it’s a “public space”. So what is it? A nice looking building with hardly any books, a few gimmicks and two cafes.

On the surface it fits the bill for all the modern awards it’s bound to get and it fits the narrative that libraries are for public space rather than renting books, but spend some time there. It’s not practical to get books from as there are hardly any books, it’s not practical to study as there is only one tiny reading room.

I urge anyone reading this article to spend more than 15m wandering around in there.
Indeed. Not only can one get a glance of a unique perspective of one of the founding fathers, but also a lot of important facts not covered in many other textbooks. One of such facts are the low heat capacities of atoms that do not fit any classical theory. This fact alone is able to kill most of the "alternative" interpretations of quantum mechanics that the popular media sell-off as "science" nowadays.
Time anxiety: is it too late?
My unpopular opinion is that Stephen Wolfram doesn't get enough credit. Yes, he has a large ego, but he remains one of the most remarkable people in science today.
Likelyhood he faces jail for this? What will become of his new company pronto.
My point is that housing isn't all easily substitutable Ferraris, BMWs, and Civics. There are also private jets and mopeds. Jets and mopeds might both be forms of transportation, but a drop in the price of jets isn't going to impact moped prices.
It seems like a perfect opportunity to let the free market solve the last mile problem.
Would you feel the same if it was you or your friend who had their life's work stolen? Would you be alright watching someone make a fortune off of your work and not even acknowledge they owe you?
You can automate things with Bash now, too, if you like ;)
I think my main gripe with Windows is that it has one less app-accessible modifier key. As a power user, this is invaluable to me and Mac has it.
And even though I’m a pretty heavy user of my local library system for reading paper books, I rarely walk in there; usually I find a book online and place a hold on it and then pick it up when they email me that it’s ready.
This already exists. It's called the LG NeoChef[1], and it's an absolute joy to use compared to anything else I've seen.

It has three controls on the front: stop/clear, start/+30sec, and a touch slider that lets you accurately set any time from 10 seconds to an hour. The slider actually works very well, and is super kid-friendly. Here's an image: https://www.lg.com/ca_en/images/microwave-ovens/MD05821693/g...

If you open the door, there are 11 more buttons for setting the power level or starting a timer, etc. The only preset button it has is popcorn, which is the only useful one. Notably, it does not have a number pad, only plus/minus buttons. Image: https://www.lg.com/ca_en/images/microwave-ovens/MD05821693/g...

It also has an internal LED light that shines down from above instead of a crappy incandescent light that shines from the side (and is inevitably burnt out).

Oh, and it doesn't have loud, irritating beeps from a piezoelectric beeper that wakes up the entire house when you're reheating your 2am snack. It has an actual speaker instead, and the touch tones are soft and the "done" alert is melodious and stops when you open the door (there's an actual handle, instead of a spring-loaded button).

Testy – A Complete Client and Server Side Experimentation Solution
Hi everyone, I am happy to announce that the second iteration of the SaaS idea that I have is now live.

Testy is a testing and feature flag framework, the initial version will focus on one of these two features and the target is to provide an easy to use framework that can be used on any kind of front end or back end technology, let it be SPA websites, back end processes, mobile/desktop apps, games, anything that has web access.

I am still validating the solution at this point, so it is only a signup page with the service description and core features.

Any kind of feedback is more than welcome!

Thanks!

> We really really need to start looking at regulations and find ways to get rid of the ones causing all these problems.

Yes, I agree, totally. Except where this is impossible.

You can't "free market" the cars out of cities. Nobody wants them gone, and everyone has vested interests in them staying: real estate, construction, parking+traffic violation revenue, car owners, car manufacturers, insurance companies, lawyers... Massive amounts of money flow through the co-existence of cars with cities.

The market's trend is to exacerbate the car problem. How will gutting regulation reverse it all?
I work for an MSP which supports Windows installs. The support teams apparently hate our LTSC customers because they require manual upgrades unlike the standard version.
The UX is incrementally improving in every release. Through just the last few major releases, you've gotten Airdrop-style sharing (the new Share menu), full system-wide indexing and instant search, a unified control panel and a ton of other things. They're moving fast, but incrementally enough that it may not be noticable—but I vastly prefer the fast-follow improvements over the 1-3 yearly 'big bang' releases Apple has done with macOS.
As someone who has used Linux (with a few brief stints into macOS and BSD) for quite some time (since about 2012) coming from Windows before that, I don't understand the people who constantly defend Windows in these types of posts...

In principle, the feature set that Windows 10 ships could be useful. I don't find it appealing personally, but if it works well for you then that's great.

The issue that I have had is that every version of Windows I have used (from XP up to 10) has had serious reliability and performance problems.

As a specific example, it seems that the one Windows machine that I keep around to play games on needs a complete re-install every 6-12 months, usually because Windows tries to update and bricks itself so badly that even "Windows Recovery" cannot salvage the install. This is a relatively nice machine (Haswell i5, 24GB DDR3), and I tend to stay on the happy path of just running the vanilla install plus Steam and a small number of games (never any programming, web browsing, etc.).

In cases where I've had to use Windows for work, I've found that most of the built in programs lag and take a long amount of time to respond to keyboard or mouse inputs (in the specific cases I'm thinking of, this was on top-of-the line Dell Precision notebooks at the time). Most of my code seemed to run subjectively much slower natively on Windows than it did in a Linux VM running on the same machine.

I'm not trying to be a power user of Windows, as I generally try to avoid using it as much as I can due to the bad experiences I've had in the past. I'm not doing any crazy registry editing or anything like that. Just pretty basic development work and gaming over the years. In that time, I've never had a Windows install where the features reliably worked, and the install remained stable for any period of time.

This is all anecdotal of course. It's possible I've just be incredibly unlucky, or that I've had a string of a half dozen machines that have hardware that's somehow broken in a way that only affects Windows.

So what I'm wondering is: all you people who keep chiming in on these types of posts claiming that Windows works well for your use case -- what are you doing? What's the secret to having it actually function reliably? I've not been able to replicate any such success.
I genuinely don't understand how people, out-weigh the benefits of zoning against the million dollar price tagged homes. What is so important, that justifies you go into debt 800K plus extra?

Personally, I'd rather pay 200K for a home, rather than 1 million $ for the same home but with zoning laws. Now, I don't know if it's a 5 to 1 difference in every case. But, we all know 5 to 1 difference in cost is not at all unusual on a per sq ft basis.
It's a cycle. Build the city around cars? Then the city becomes spread out due to poor land usage and cars become a requirement. Since the city is more spread out, public transit is both more expensive (since you need to cover more distance) and less efficient (you service fewer people per mile).
Magento development cost breakdown: How much does a Magento store cost?
Always amazed me when buying something of Amazon and it's shipped from China cheaper that if shipped domestically.
That's up to you. The reason I asked the question is because it's one, based on the comments here, that I think many people weren't asking themselves. And that's akin to condemning a man for 'x' without ever asking yourself if 'x' is even wrong.

As it's a moral question, there's not going to be any unambiguous right or wrong answer and we're all going to have different perspectives. One might even argue that you have a moral imperative to take his money for practically any reason so long as you are not directly assisting his other actions, since it means you are taking a chip, regardless of how small, out of the resources he had to carry on with said other actions.

As another example on this topic in Columbia the big drug dealers would frequently use their ill gotten wealth to do positive things such as fund schools for local towns. And these guys were involved in far worse behavior - murdering large numbers of people, often in brutal fashion to send a message. And that was similarly no secret. Should the townspeople have rejected their offer?
Also try JScript. It's underrated.
I use macOS at home but have Win10 in the office. I've been using Windows in some capacity since 3.1. Win10 is the first one I've found usable.

Going from Win XP at home to OS X, I found it astounding that my PowerBook could go months without a reboot. Likewise, my MBP astounds me daily that I can't remember when I last rebooted.

My employer's Win10 laptop is like that as well: I don't think about rebooting it anymore.

MS is on a good trajectory, finally, with its os.
The core of the product is a bunch of regex or something smarter?

Odd that a product that want you to base your legal safety is not more transparent about the actual implementation on the initial page, instead it reads like an advertisement for closed source SaaS.
Yeah of course. Are you guys mainly focused on classic 4 year universities or do you have your sights on/have you worked with community college and trade schools as well?
"Theft of trade secrets" is how Silicon Valley was built.

Fairchild was "theft of trade secrets" from Shockley; Intel was "theft of trade secrets" from Fairchild. When Camenzind left Signetics and designed the 555 (under contract to Signetics), he was "using trade secrets" of Signetics; in today's legal environment, they could have just ordered him to stick around as an employee and work on a less risky project. MOSTek was built out of "trade secrets" of Motorola. Unix was only released under a source licensing agreement, and for decades the Lions book, the bible for Unix kernel engineering, was illegal and could not be printed legally, because it contained "trade secrets" (and copyrighted code!) of AT&T. (Or, rather, Western Electric.) Indeed, economists have published a number of papers arguing that that California's prohibitions on non-compete agreements and on employer ownership of private work product underpinned the 1970s–1990s shift from Boston to Silicon Valley.

So this movement toward resolving such conflicts in the courts, instead of by companies competing to out-innovate one another, is very troubling. Investors, and in this case Google upper management, are killing the goose that laid the golden egg; they want to shift power from engineers, who make things, to lawyers and investors, who specialize in getting paid for them.

This is probably a major factor in the widely-observed shift of the center of innovation from Silicon Valley to Shenzhen, where shanzhai ("theft of trade secrets") is a way of life.

I live in a poor country which is poor mostly because the established economic powers are able to strangle new centers of wealth creation in the cradle, using the government and laws. Don't let that happen in your country.

Engineers create wealth. Lawyers and investors just compete to privatize it.

> OK, it's a cart and horse affair as it is the resistance that causes the heat,

Most of the heat comes from semiconductor conduction, leakage, and switching. Superconductors don't fix that. Not to mention, a major factor in resistance is diffractive losses is the ohmic layer surrounding transistors. The ohmic layer is necessary because direct metal-semiconductor connections create blocking diodes. The width of those wires at the connection points is so small that electrons could barely squeeze through. That was the reason we switched to "high-K" dielectrics, which have higher classical resistance but lower electron scattering. Superconductors have similar problems with entry and exit into superconducting areas.
Most engineers I have met in Silicon Valley have a very high standard of personal ethics. For example, I have seen engineers risk their own careers to insist that their employers give back to open source projects when the employer is in violation of an open-source license's terms.

But I've also seen a few, rare bad apples. There are some people who are borderline sociopathic, who don't think twice about theft, misdirection, misappropriation of credit, and throwing co-workers under the bus for personal gain.

Usually, such people are not caught, and are not punished ... ever. People who learn about such sociopaths, just avoid them.

But sometimes these sociopaths go too far. This seems to be one such case.

This prosecution will discourage the very worst behavior and it will feel therapeutic for people that have felt victimized by various sociopaths who used them as ladders on the climb to fame and wealth ... but the less criminal kinds of sociopathy in the workplace is probably never going to go away. And there's no real way to stop it.

I haven't been to Google or worked with Google in a long time, but for a while there, say between 2010 and 2015, I felt like it was chock full of sociopaths in mid-level management. I don't even think Anthony would have stood out as particularly sociopathic in that environment.
Well, that sounds pretty much like flying commercial flights or traveling by bus. So I guess based on my travel history, answer must be yes.
What an excellent tool! Noted for future reference.

Except you benefit from roads even if you don’t use them: stuff delivered to you or via stores always comes via road. Even if it is transported by train, it still has to get to the shop. Mail service uses the roads, police, fire, ambulance also uses the roads. Firemen and Fedex aren’t doing their jobs taking the train. The refrigerator in your house didn’t arrive on the light rail. So even if you think you don’t use roads — you definitely benefit from them. However, I fail to see how I benefit from light rail I never ride. My electrician never showed up to my house on the light rail. Amazon isn’t shipping packages on BART. Public transit is a luxury, while roads are a necessity for the simple reason that ambulances, fire, police — they all need roads. Deliveries need roads, but they don’t need public transit.
101 videos from the CCC 2019 ? This is a good day.
Mopeds are illegal to build although (SRO) and the minimum legal house is a civic, and nobody protests the building of local large single family jet mansions. And you haven't seen the used market price of a porsche in a market with a lot of them ;) Berlin 15 years ago is one example of that.

And what people call 'luxury jet housing' is usually really sad 600sqft housing that would be called honda fit housing elsewhere.
The 'phones home' argument doesn't really add up—there's plenty of control over this at this point, and every OS is calling home, macOS included, to some degree. The advertisements thing happens out of the box, and is trivial to remove (if my memory is correct, Safari harasses you about being the default browser, too, if you try to change it). The updates to add features thing.... isn't an issue for me, but YMMV.
This is all just so you can continue to live your life and not sit in jail while waiting for trial correct? That just seems wild to me. If you don't have the money, or can't get a loan, you probably lose your job due to being in jail, which now your entirely livelihood is at stake. It just seems so broken.
What might your answer be now? Does commercial success necessarily mean that ethical violations are unimportant? (not trolling, just curious how you'd articulate the importance of ethics in the vacuum of legal or economic consequences)
Great article, I liked that it illuminates the question--whats a trade secret vs knowledge from on-the-job-experience? And where's the line across which a company can say you've used a trade secret? It's scary to think that one of the outcomes of this case could be a precedent that allows companies to go after what's in your head.
Nutshell looks great. Wasn't on my radar at all, but I'm going to start evaluating it next week. Good job Andy!
> This is especially true in monorepos

Not in my monorepo.

I have compile time boundaries between modules and I cannot make them particularly entangled with each other.

Maybe the problem you have in mind, is more likely to happen in dynamically typed languages? Where there's no compiler who can say "No."
If it's free then it sells your data. If it isn't free then it probably also sells your data, but maybe not.

I agree. It's a tough one because his ego is so huge he's often accused of taking credit for other peoples' work. My impression from reading through A New Kind of Science is that it wasn't some plot by him to take credit for the whole of CA research but that his ego just kind of caused him to write in such a way as to give that impression.

All personalities aside, I feel like the core thesis of this and other books on CAs, fractals, computational physics, etc., are sort of like the edges of some higher scientific theory that we don't yet understand. The entire universe looks like a big fractal with structures repeating with some variation at different scales, and we don't "get" this beyond hand-wavey pure speculation that starts sounding like New Age babble. I wonder if we're just at the edge of being smart enough to grasp this higher order of understanding and if we did we'd have among other things a unified theory of physics. It makes me think of what chimpanzees might feel when we try to teach them language and basic mathematics. They can almost get it.

Maybe there are beings out there that "get it" and they're out there doing things that to us would be indistinguishable from magic.
Left and right is not really useful. The issue is that there are multiple degrees of state control. But state control comes in more than one flavor. States want either to control what everyone thinks, or to own the economic output of all individuals, or some combination of these two. The state control axis is the most relevant, and its endpoints can't be labeled left or right.
It was two decades ago, but when I lived in Germany it also
seemed that they lost about 50% of the parcels that we sent between Germany and the US.
None of this points to free market being at fault.
There are! The second paragraph in my first comment goes into detail on this. You can purchase the font and get the files, but it's still on you to track views and make sure the files are delivered to the browser safely (preventing easy downloads).

Edit: it seems this entire thread is heavily downvoted -- both sides of the argument. Is it off-topic? Bad faith? Why the downvotes?
This is not a correct reading of Christensen, nor close to it.
That's tragic and awful. I think calling this a "shortcut" though is misleading, at least from what the times is reporting here.

It's one thing to own your own brain, it's another take 14K files, including circuit board designs and lidar designs. It's yet another to start using them at new-co that is a direct competitor to old-co. I'm by no means an IP fanatic, but that really does cross over to theft in my mind. But, on balance, the very specific details really matter here, so we'll see...
Libraries are one of the few indoor spaces left where you can spend time there without a requirement to purchase something.
There's an element of truth in what you are saying. But in this case Lewendowski didn't build the stolen technology. He misappropriated the work of other engineers at Google.

It would be one thing if he just left with his own work. That would be more understandable.
