You gonna get rid of jets and trains, or make them electric too?

The petrol industry has many friends, they serve many markets.

Look at what comes out of a barrel of crude[0], an incredible number of products which aren't going away, even if every car/truck/bus/vehicle on the road was electric.

Physics is a harsh mistress.

Back of the envelope numbers: Tesla uses 75KWh batteries at 400vDC to go 250 miles. Trying to refill that in 5 minutes is going to be dumping some serious power into the battery in a very short time.

To recharge 75KWh in 5 minutes (1/12 hour) at 100% efficiency would take:

(75,000 / (5/60)) / 400 = 2,250 amps (900KW)

That is going to be one BIG connector and cable going into the car... and the battery's internal wiring will need to be increased by 10x (or more) to carry that current to the cells.

For comparison, the Tesla SuperCharger uses 400v at 250 amps (100KW). To do the charge in 5 minutes would be an order of magnitude more power. It's a pretty good bet that the SuperChargers are close to the max charge current the batteries can accept.

Any inefficiencies in the system will result in waste power that will also have to be dissipated - if the charger were 90% efficient, it will have to get safely dissipate 100KW (1MW * 0.1) for the duration of the charge. A quick google search indicates lithium ion batteries are close to 100% efficient in charging(!) so that really good - the charge won't be cooking the cells themselves, although the battery's wiring and charge current control circuitry will need to be kept cool.

Much harder than it sounds. Java, Adobe, and Google pumped a few hundred million dollars into previous attempts and they all failed. WASM learns from two decades of previous attempts and we are finally getting something sustainable[0].

Thanks for the heads up on Electron - I was going to look into onboarding this for our team until that. We have more than enough in the way of crufty crapplications already.
I'd never trust a developer that's only worked on green field projects, they're oblivious to the mess they leave because they aren't there long enough to feel the pain of their design decisions. So you've got one up on a lot of people there.

Aside from your own projects, look for opportunities for other projects at work where you can start with a fresh technology stack. Some of these projects might be taking over the non-core functions of the main app. For instance, chances are a lot of the UI is sub-optimal (generic crud based) for some specific users. You might be able to create a slicker interface that makes it easier for them to do specific tasks that feed that data into the main database.
Ask HN: What's the preferred stack for your app as of today?
Data: Mongo vs Postgres vs MySql vs Sql Server
Framework: Node vs AspNet vs PHP vs Other
UI: Angular vs React vs Vue

Well, for the moment, the record is exactly the opposite of that prediction.
I think you may be reading too much into all of this.

Oracle sued alleging copyright violation. The ECJ ruled that what UsedSoft was doing was not a copyright violation.

Applying that to Steam, it would imply that if I sold someone my Steam key for a game I had purchased I would not be violating copyright. It does not necessarily imply that Steam has to make or allow the key to work for the buyer. That's out of scope for copyright law.
> Xeon Phi's clock low because the die is massive.

That's not the main reason. The main reason is perf/W for highly parallel workloads.

> The downclocking for AVX started with Knights Landing.

You're mixing things up here and that statement is incorrect too. AVX throttling started with Haswell-EP [1,3] (Intel kept it quite hush-hush avoiding mentioning it in products specs and such).
Secondly, Xeon Phi is the HPC product family and KNL is the codename of the 2nd generation of these arch [2]

> My Boardwell-EP Xeon stays at 3.0Ghz even when I (ab)use AVX2.

In that case you're most likely either not using more than 1-2 cores or you're overclocking (or perhaps monitoring incorrectly), see [1,3].

Yes, quantum supremecy has not been demonstrated, but the question of whether non-quantum Turing machines can accurately model all physical laws has not. Of course, we don't even have a quantum theory of gravity for them to model at this point...

What is regularly? We probably take 2 road trips of 3500km a year, probably 4 trips of 1000km a year, and probably 10 trips of 350km a year. In the Western US things are very spread out. We live in a city of nearly 3 million people, but the next three closest cities of comparable or larger size are 300km, 700km, and 1000 km away. And if your wondering why we don't fly, it's because we have 7 children so it's cheaper to drive.

Speaking as someone who is studying both linguistics and Japanese, this this type of comment is just cringy to read. In the grand scheme of potential "languages" Japanese and English (as well as all natural human languages; including signed languages) have incredibly similar grammars. It is only when you restrict your view to the range of human languages that Japanese and English start to look incredibly different.

With regards to your link. Japanese absolutely has subjects.

The question of presisly what -ga marks is a bit more controversial, but calling it a subject marker is a perfectly defensible position. Indeed, having studied linguistics before studying Japanese, I found that thinking of -ga as a subject marker and -wa as a topic marker made the distinction easy for me.

The point of this comment is not to say that we should be teaching English-native Japanese students that Japanese does have subjects and -ga marks them. I am not qualified to make that judgement, and my benefit likely came as a result of leveraging my linguistic studies.

As others have pointed out, thinking of Japanese as analogous to English is counter-productive for most students. This is despite the fact that Japanese is analogous to English in most cases, including (potentially) cases where seeing the analogy could be counter productive.

Returning to the original article; this is a good indication that just because something is wrong does not mean that it is not useful. Anthropomorphizing might not be technically correct, but it could still be a useful tool to help our human brains make sense of the world or subject matter. In the same way that saying "Japanese does not have subjects" might not be technically correct, but it might still be useful.
MD#1: Scaling the Event Stream
If your first installs are going to be gcc and i3, then I think you should give the standard Arch install a shot. It takes a basic understanding of what's happening during the install process, and I'm guessing if you're kicking off with i3 then you're comfortable with things like partitioning and configuring a window manager. If that's the case, installing Arch will teach you things that an Ubuntu install definitely won't, and you get a fresh clean minimal install too.

Scott is a friend of mine. I've talked with him face to face about this very subject. He disagrees with Penrose, but his objections are far more nuanced and respectful than anything I have seen here. He would be horrified to see Penrose belittled and his arguments not given a fair reading. Penrose is an intellectual hero to Scott and someone to be admired.
You might also try "Arch-Anywhere". It's got a very nice install script, and is minimal. You'll end up with a very basic installation of Arch, probably similar to the one you'd get with a more manual installation. This is how I got started using Arch, and I've learned more about Linux than I ever would have been able to with Ubuntu or Debian.

https://arch-anywhere.org/

Arch has turned out, surprisingly to be much easier to maintain, since things are well documented and consistent.

Avatar was like the highest grossing movie of all time, and it was just Pocahontas with CGI.

Just because people use it doesn't mean it's artistically meritous.

My opinion isn't subject to YOUR conditions. I've played Pokemon games since a very early age, and I had certain expectations for the experience that weren't even close to met in the final product.

The marketing was vague, but it's not like a complex concept either. It's pokemon on the go, in the real world. It's not a scavenger hunt game, and that's what we ended up getting.

I could be a bit nicer about how I explain it, but I LOVE Pokemon and this game is a giant blemish on the legacy, as far as I see it.
> But even the most charitable reading of the facts would find that Levandowski downloaded the files to an external disk

Actually, no. All they have is that a few days after an SVN sync, a USB card reader was attached for 8 hours. There is no evidence presented that he actually copied any files, much less the synced SVN files, to whatever was connected with the USB card reader. He could have plugged it in to copy his personal SSH keys to the machine and left it in until he left for the day for all we know.

There is separate information that he exported a single Google Drive file to a personal device on January 11, titled "Chauffer TL Weekly Updates - Q4 2015". There are further logs about other high level engineers that subsequently left that also exported Google Drive files to personal devices prior to leaving as well.
If you're not familiar with linux much, the best distros to start with are the ones with the largest communities. That means more support for edge-case stuff.

If you've used Debian before, stick with it. Your system's specs are fine; you don't need a 'lightweight' distro for it. [1]

Debian has a couple more warts than Ubuntu, as the latter is more user-friendly by design, but Debian is 'cleaner'. You'll also have an easier time if you use Debian Stable or Ubuntu LTS releases (and just upgrade necessary packages). 'Rolling distros' are more up-to-date in general, but they can break on you (fine if you don't mind fiddling, but annoying if you just want to get on with stuff). Rolling distros become less painful as you skill up in unix-ese.

[1] actually, depends on the ram of the system. the CPU is fine, but I misread max supported ram as current ram. If you've got 4GB, you're fine. If you've got 1GB, go for a lightweight dekstop (and stay away from modern websites).
I'm going to throw an alternate thought out there just for you to chew on... try Slackware first. The common rhetoric is that Slackware is difficult to work with and not for the weak of heart.

That has absolutely been my experience too (I still have my 1995 Infomagic Slackware CD... the horror.)

But are YOU the weak of heart? Perhaps not, coming here to ask such questions. And, IMHO, what you learn from fighting with a more raw linux distribution like Slackware is actually a useful learning tool. You can learn a lot about drivers and hardware systems by having to fight to get them to work.

And as soon as you get sick and tired of it, install something else that someone more forgiving has already mentioned. :-)
The tone of this post is a little flippant, but ultimately, I have to agree.

It comes down to how much trust the executive sponsors have in the face of the engineering org, and how the business views technology, as responsible professionals or children who have to be closely supervised and monitored.

Nurturing that relationship is one of the most important jobs of an executive/C-level engineering manager.
I use Arch but if you are starting out I would recommend Ubuntu. It's probably got the most youtube videos, online articles, troubleshooting questions online. This make things a bit easier. For example, you mention i3 - probably the best i3 tutorial on youtube is running ubuntu. -> https://www.youtube.com/watch?v=j1I63wGcvU4

https://www.theverge.com/2017/5/30/15712300/alphago-ai-human...

"Say you’re a data center architect working at Google. It’s your job to make sure everything runs efficiently and coolly. To date, you’ve achieved that by designing the system so that you’re running as few pieces of cooling equipment at once as possible — you turn on the second piece only after the first is maxed out, and so on. This makes sense, right? Well, a variant of AlphaGo named Dr. Data disagreed.

“What Dr. Data decided to do was actually turn on as many units as possible and run them at a very low level,” Hassabis says. “Because of the switching and the pumps and the other things, that turned out to be better — and I think they’re now taking that into new data center designs, potentially. They’re taking some of those ideas and reincorporating them into the new designs, which obviously the AI system can’t do. So the human designers are looking at what the AlphaGo variant was doing, and then that’s informing their next decisions.” Dr. Data is at work right now in Google’s data centers, saving the company 40 percent in electricity required for cooling and resulting in 15 percent overall less energy usage."
Yes. I've been hopping around on too many distros in the past and always come back to LTS versions of xubuntu. Everything else just creates a lot of unanticipated pain or annoyance after some usage. Lubuntu would be the next best, if you really can't get xubuntu to run properly... But I would give xubuntu a serious try first, as it is so much more of a proper OS. Shouldnt be too far from lubuntu performance-wise if turning off some of the window animations etc.
It is incorrect. Penrose emphatically says the human brain is governed by physical law. To assert otherwise is just factually incorrect. Read his books or read his papers. If you disagree, please provide one quote that shows otherwise.

I am sorry to have said "go home" and will refrain in the future. Still, you have lodged what I consider factually incorrect assertions about Penrose's argument. When asked for evidence you have provided none.

There is a community distro of Manjaro which already includes i3: https://sourceforge.net/projects/manjaro-i3/

It was a big help to get more into i3. It also includes a lot of helper scripts. I used them in the beginning to get things done and later switched over to the "real" commands. inst -> pacman is an example for that.
Any time before the advent of "supplementary materials" pretty much meant that you had nothing more than a highlight of the method. It was terrible indeed.

Cartels are unstable by their nature, OPEC is the exception not the rule. Cartels can only thrive when there is a lack of competition and strong enforcement between member nations. There is a reason why we don't hear of coal or natural gas cartels which are substitute goods for oil.

This almost feels like bikeshedding but...to be fair, pretty much the first thing anybody does with a new work organism in biotech is make it glow and it's been that way long before CRISPR! There's just something about it that people find irresistible.
I recently put a "lightweight Ubuntu-based Linux distro" on my gf's underpowered laptop. It really sucked. Hardware support was shot, software selection is limiting, and in general it's just not set up the way the rest of us expect. Get a standard distro, even if it might not be the ultra-fastest build out there. All the help forum search results you will find are based on the standard distros, and this will make it easier to fix problems and learn quickly.

You honestly start with something incredibly common like Debian, Ubuntu (both mostly the same but with important differences in usability) or Fedora. The simplest way to try different distros is to make /home a separate partition for your user files; everything else is disposable.

If you have a lot of time on your hands, try LFS. If you want to see a stripped-down but not "minimalist" distro, try Slackware. If you want to install lots of distros and try them out one by one, use QEMU, VMware Player, VirtualBox, etc and install each one and play with it, but hardware-specific changes you'll only find by installing it natively.

You are actually incredibly lucky to be using a 6 year old machine. The newer the machine, the less Linux support there is for it. I recently got back to Linux with some modern laptops and it was a friggin' nightmare to get everything working. One distro's installer didn't properly support the naming convention for a hard drive controller. A bunch of the media keys aren't supported. Getting hybrid graphics to work took days. Apparently my wifi card has unfixable problems with 802.11n networks in Linux. And I am still unable to connect to a bluetooth headset. Stick to the old hardware, try different web browsers until you find one that won't crash with only 1GB of RAM, and have fun!
1) These are all specialty bikes, and well outside the price range suggested in the GP ($250-$500)

2) No, my partner can't ride a bicycle. As advanced as your powers of remote diagnosing may be, they're wrong. It's not an option. We tried. (I'm from Germany. I'm somewhat acquainted w/ the idea of specialty bikes, and trust me, I looked at them)

3) Theoretically, I might fit my shopping needs on a bicycle. Alas, transportation here is so completely shot that taking that bike onto the road (what bikelanes?!?) is essentially a suicide attempt. Colleagues who have the ability to bike to work usually end up with about 1-2 severe accidents (broken bones) per year.

And yes, e-bikes might address the distance problem. I still can't do it in much less than 2 hours because... I live in LA. Nobody goes 20 miles in less than two hours ;)

4) Even if there was the political will to make it happen, no, not all American cities could look like this without ~20-30 years of rezoning and construction. US city planning is... special.

European solutions cannot simply be transferred to the US, as much as I'd wish for that. (Remember, I'm German - I've lived in cities friendly to people, instead of cars. I miss it).

And that's why the suggestion of getting rid of the e-car subsidy in favor of bikes won't work in the US. Nobody will use the bikes because the infrastructure doesn't exist.

That doesn't mean we shouldn't also work on improving the infrastructure, and on changing city planning, and creating workable public transit, and all those things - but they're long-term projects.
I wish we could start prosecutions like Nuremberg's once we topple the Venezuelan regime that has brought so much misery to our country. It is unbelievable how so many corrupt politicians are living large around the world and no country ever asks them about their billions of dollars in sudden fortunes, their yachts, ferraris and multiple properties. They have stolen trillions of dollars in almost two decades, but this is not only about the money, also the millions of displaced and hundreds of thousands killed at the hands of paramilitary motorized gangs armed and supported by the dictatorship.

There won't be closure until we hunt them down everywhere they hide, and the whole world has become much more smaller thanks to the internet.
I don't know a lot about this topic, but my understanding is that (unlike many languages), English evolved where more formal language became popular, and casual/familiar language died away. For example, "you" is the formal version of "thee" (similar to "vous" vs "tu" in French).

This projection that electric cars will soon become cheaper than gas cars assumes an exponential decay in cost. All exponential trends ultimately cease due to some physical limiting factor. We're seeing Moore's law sputter to a halt because it is getting more expensive (and not less) to make smaller features on microprocessors- semiconductor manufacturing processes are just not scaling the way they have for decades. Nevertheless Moore's law was a truly exceptional exponential ramp unrivaled in the history of technology. Does battery manufacturing have the same advantages that will allow for a tremendous long-term exponential ramp analogous to Moore's law? I am wondering how long it will take for battery technology to "hit the wall". Hopefully batteries will become significantly cheaper, safer, and faster to charge but I am skeptical that we will be able to ride this exponential curve for anywhere near as long as we've benefited from Moore's law. I hope I am wrong.
Agreed that it will be different once AGI completely supplants human efforts, but at that point you are examining the singularity. Robots that are better than humans at everything, could also design better robots etc... If/when that happens, economics and jobs will be worry #96 on the list of things to be concerned about.
