I ride bikes and from a practical standpoint, along with small size and manoeuvrability, the acceleration (a result of torque) is one of the most useful attributes. Much moreso than top speed, or even speeds significantly in excess of the posted limits.

Bikes don't tend to have high torque in general, but their light weight and gearing are designed to maximise what torque they do produce. This means there are quite a few that will do sub 3 seconds to 60, and sub 5 seconds is practically the norm.

What this means is that you can more easily get past, and through, traffic because you can safely take advantage of gaps that no car can. Also, that sense of having your arms ripped out of their sockets and hanging on for dear life is fun.

Still, there's something to be said for going really fast as well: the feeling of the world blurring past you, and the road or track flowing and snaking underneath you like mercury, is hard to beat (if sometimes a little terrifying).
Hello to everyone. Intelec AI is a platform to automate building and deploying machine learning models. It's web based and supports GPU acceleration. You can download and try it for free.

Main advantages of Intelec AI over cloud based autoML solutions:

* Free to download - You don’t have to pay anything to start using it.

* There is a 15 day trial period for testing the premium features. A lot of functionalities still stay free after 15 days. For example, training model and task creation. It means that you can train a model how long you want, if you’re not satisfied with the result, you don’t have to pay anything.

* Privacy - If you have a confidential data, which you’re not sure whether you’re allowed to upload to a cloud server, then the downloadable version of Intelec AI is for you.

Please follow this link https://www.intelec.ai/install to learn more about how to set it up on your computer. Thanks for your attention. We hope you like it.

How can it "choke way too quickly with a 100+ tabs"??? Your brain will choke way before the browser with that much open.

The obvious upgrade is to have no operator at all. It boggles the mind that we're seriously talking about self-driving cars on shared roads, and at the same time don't have self-driving trains, and instead allow them to fly off the rails every year due to operator error.
Woah i wasnt trying to be racist the Fremen in the books literally go on a genocidal jihad later. In the first book they hint at just how far their fanaticism goes and explicitly includes a part where they hijack a vehicle and crash it into Harkonnen troops. The political undertones would be interesting to see play out in this modern climate.
Cleverness is not related complexity in any way. Software is going to be complex. Cleverness is just going to make it harder to read/maintain.

I prefer Go over other languages. I like the part that there is no cleverness around it.

But why are you bothered about what google thinks of its engineers ? You can write everything in Haskell, why stop at Java/Rust ?
Even if it could be operated safely by a person, it still would have no practical value. This is not a transport feat, it's an engineering/brand feat.

They do in a lot of metros, although it's often very hard to retro-fit. The DLR got it at build-time. [1]

One of the big issues is 'degraded working' where there's been some sort of failure (or perhaps adverse weather conditions) which means trains have to operate on vocal authority to proceed on sight. The problem then becomes as hard as driverless cars - you have to know when you've reached milepost 70 or the next set of points by sight and it's really bad if you miss them. Arrival to and dispatch from stations without platform-edge doors is also tricky and human staff are often required to manage the process.

Interesting. So basically, the "rc" in ".bashrc" has a meaning similar to the "EXEC" in "AUTOEXEC.BAT".
It's weird that repairability (either right to repair, or simply technical feasibility) has been a huge topic for at least 10 years in cars, mobile phones, home appliances, etc. And yet i haven't seen any end-user product really advertising it.

Worse, the trend seems to be even more toward cheap black boxes that you'll change entirely whenever they break.

As another example of things going the wrong direction: a few months ago i saw a video about a Tesla test, and the car's engine refused to start. The owner had to turn it off and on again so that they could start the engine and begin the test. As a software engineer, that made me feel so bad...

Is there any solution toward better quality products, aka : having the benefits of cheap electronics and advanced functionalities, but with the longevity and ability to repare and customize of the old mechanical technology ? Is it a business model problem ? a technical one ? a supply chain / pricing one ? marketing ?

I keep wondering.

It is not futile. You can drive to a race track and have fun without having to rely on a trailer and another car.
From what i can see, the response only contains the comment you upvoted and its children. It's important for people like me who don't have Javascript, but the JS voting system could probably do with a simple HEAD request.
Indeed. In Europe we still have huge issues with declining home ownership, youth unemployment and precarious/low-paid jobs (incl. the 'gig economy') etc.

I did okay-ish (home ownership still seems impossible), but when I see some of my high school and uni friends stuck in bad jobs with seemingly little hope of escape you can understand the despair.
If you're a tab hoarder, Chrome does seem to have gotten worse in the last year.

Usually the GPU process. Even if your tabs are all inactive, killed by something like Great Discarder, the GPU process continues to use a lot of RAM (2GB in my case, at times) and CPU.

I am not sure if it's a Mac-specific issue though.
The US baffles me sometimes.

How can a civilised country allow this to be?
Strange how organic content not contaminated by the AdBuddy company (twitter flooded with their sponsor links and almost no real content) doesn’t even consider Brave as an option.
From my experience when something like that happens, i.e., HackerNews sends back 10K after an upvote, there is a reason for that. We might not know the reason, but the developer who did that had one and at the time it was probably a good and valid reason (and might still be).
Dune has often been interpreted as a story that contains metaphors to nodern politics such as how the spice dependence is similar to our oil dependence and undertones of how authoritarian regimes try to control the fates of peoples. A lot of the events in the books can be drawn as parallels to our history and modern day situations.
perhaps chassis and suspension may benefit but with rapid electrification impending in the future, even that is of dubious value.

A Bugatti is like a piece of jewelry in my opinion - beautiful but of no practical value.
Even in that case a much lighter (and cheaper!) car like an Atom or Caterham will be a lot more fun than one of these hulking great monstrosities. Often faster as well, depending on the track.

It's not about choosing the right index. The point here is that the database can only read the index (without going into the table) if all the columns you need and use in where clause are in the index. Usually index segments are smaller, so it could be faster. I am talking from the Oracle perspective, but I believe PostgreSQL would work in a similar way.

Don’t be daft.

If the Homebrew team aren’t already busting ass to rewrite brew in Objective-C, and negotiating to get it distributed on AppStore or—ideally—included in Xcode as standard, then they’ll have no-one but themselves to blame when they utterly fail to capitalize on the massive market opportunity Apple has handed them here. Believe me, porting brew is a nothing price and the simplest step by far.

This is a once-in-a-product’s-lifetime chance for a proven FOSS platform not only to grab ten million new users but to influence a global platform vendor’s direction too. Fail to seize this opportunity or blow it execution, and you won’t get another (I speak from painful experience here).
Thank you for this! Just installed and a quick smoke test provided a much nicer experience for me. :)
I can confirm. Just upvoted your comment with JavaScript enabled, still has 10 KiB transfer.

Are we sure he never completed it? Or are these just missing parts from the (pirated? preview?) online PDFs?

Because if that's it, then it was just two points he was making, 1. Null-terminated char arrays are "defective"/unsafe, and 2. Don't omit curly braces, for which he seems to have received a lot of backlash, even though those are quite valid points. I'm guessing it may have something to do with taking it up against the grandfathers of C and his rather ...hands-on writing style?

Critique 1. isn't actually that controversial, and does have merit[1], and 2. is a stylistic decision, that even John Carmack[2] would agree on.

Going faster than the speed of sound would be interesting and a somewhat "non-arbitrary" target.
Shitting on users is bad no matter what site you make.
You could get close just with turbocharging which will lower the torque curve such that max torque is somewhere around 1500 to 2000RPM.
Incredible! A celebration of silliness in all its absurd glory. I was not expecting Bugatti would do a top speed run at least for a few more years for the tyres to become available so I think we all expected Koenigsegg to be the first to 300mph. Massive achievement for Michelin as much as VW.
Dark mode would be pretty nice, negative colors on my phone works I guess but it'd be nice to have real support.

A more likely reason is that most of them are really badly written. The books feel as though the writers wanted to make a quick cash grab using existing IP, but completely misunderstood what the exact appeal of the original works was.
What a bizarre distinction. I'm not even sure I understand the classification. Art can make the ordinary transcendent - it's the treatment not the subject matter.
I was more putting scale into perspective comparing the rest of the country to Silicon Valley. A 10-20% variance is believable. But still nowhere near SV/ west coast total comp.
True. And I can see that some webs gradually stop working if you are using JS blockers. For example Aliexpress used to work fine with uMatrix. Now, if I click on the Next page in the paginator, it behaves like it loaded the next page, jumps to top, but it didn't - it just changed URL location. So I have to CTRL+R to reload the whole page to force their server-side rendering. I know it is theoretically my problem but I have to use JS blocking to stop (for me useless) ads and malware scripts. If they just loaded content from their domain or sub-domains, it would work perfectly fine. And if it were old-school server-rendered website, it would probably work faster, as it was discussed here some time ago. I have a feeling that web devs are sometimes over-engineering it. Web browser is HTML viewer, not an operating system.
Id agree my expensive oakly's with prescription lenses do subjectively feel better in terms of vision.

Not sure what my brain has to do with it. I can handle hundreds of tabs just fine. Put simply: Chrome can't handle my workflow. If it can't handle my workflow, it isn't viable for me as a daily use browser. And in my experience, every time I've tried it (and I've tried it every year for good measure), I've become frustrated by how badly the performance degrades so quickly.
Correction: transmitting the track signal to the cab is how high-speed trains worked half a century ago. That's SOP on most modern trains by now, with high-speed rail using moving blocks now (no more physical signals at predefined distances, control system negotiates the safe distance for each train, based on realtime data).
The proofs of concept accumulating in this space are so exciting. It's hard not to jump straight into runaway speculation.

Very odd article..

Article has very little to do with title. The title is clearly intended to be clickbait.
Sorry for a tangent. But I must say I'm a fan of your answers on physics SE.

It's a great resource for people with basic undestanding of fundamental physics and some experience with math, along with John Rennie's

Nice to see you here. Keep up great job popularizing scince on a bit higher level. Kudos.

For my money, the more impressive 300 was broken 46 years ago, namely 300mpg (US), but has since increased to a staggering 12,665 mpg.

We've fetishized the wrong denominator!

For the Veyron I know they developed special tires with Michelin to be able to handle the extreme high speeds.

Such development might help "normal" tires improve in durability.

I can imagine this is something that happens in a lot of area's. Pushing every part to the extremes might help make them more reliable under normal usage.

Ultra high speeds also require efficient aerodynamics, which in turn helps reduce drag/fuel usage.

>Coming to Go after Python was not only a joy, but I was able to easily implement concurrency and improve the performance of my game of life simulation side project by something like 25x.

Python is notoriously bad at both these things though, so it's not a very high bar. I think a more meaningful comparison would be to languages like Clojure, Erlang/Elixir, Rust, or any other that has concurrency as one of the top priories, but makes different tradeoffs.

How strong are your coding skills in other languages such as Java, Python, etc.?

If you have mostly been using HTML and CSS for front end development then you could focus more on the information graphics side of things (read Tufte et. al.) If you really like to code in other languages then you could get into shaders for the graphics side of things or data science if you want to do more researchy stuff.
And we get there, we will strive to achieve Warp 10
Top Gear actually did a road test of a Tesla S vs an Aston Martin starting at 30 MPH and the Tesla dusted the Aston Martin. Considering electric motors start with max torque, and the stats that are easily googlable, the Tesla would have no problem with the Bugatti.

Never mind the Tesla is smaller, has a lower center of gravity, and costs 15x less and has more range.

And it's probably worth noting that the Tesla is almost certainly software limited.

Also, I haven't test-driven a Bugatti, but I've tested a Tesla. My wife compared the acceleration to a launched roller coaster. I entered the turn onto an onramp at 20 mph, exited the 90-ish degree turn at 60 in the same lane, and hit 80 by the time I realized I needed to take my foot off the pedal. We weren't halfway down the ramp. What was really impressive about that was the turn: plastered into the back and the side of seat at the same time, traction like it was on rails to whole time. It is quite possible the car was outperforming my nervous system's ability to orient.
What do you think about https://booxia.wensia.com ?
Modern rail can (and does) run autonomously, at 160 km/h. How-e-ver, it can run autonomously about 90% of the time...and it's far, far more cost-efficient to keep a driver in the cab than to add reliability nines here: detecting and reacting to humans is far harder for machines than for humans (think Elaine Herzberg, but at 160 km/h).
I am not a gamer. I buy all my laptops second hand. Current one is a Lenovo Thinkpad X??, 14" IPS screen, mate of course. Linux support may require you to tinker a bit.

I like a lot the Dell Latitude line, they all have a mate screen but not always IPS, and they used to have a real keyboard, not chicklet. Supported by Linux 100% straight out of a normal installation.

My kids have Fujitsu Siemens with Wacom digitizers, 13" screen, lovely keyboard: very sturdy, but hefty by current standards. My wife has the only new laptop of the family, a Dell Inspiron 13", thin and light.

I only buy with Core i5, i7 CPU's, seldom Core i3.

At work, they buy HP and I would not recommend.

You can infer my requirements: real CPU, reliability (pro oriented product lines), mate screen with stable colors, very good keyboard. That last point is getting harder and harder to fullfill.
> But now let us follow the subsequent development of photography. What do we see? It has become more and more subtle, more and more modern, and the result is that it is now incapable of photographing a tenement or a rubbish heap without transfiguring it. Not to mention a river dam or an electric cable factory: in front of these, photography can now only say, 'How beautiful.' The World is Beautiful - that is the title of the well-known picture book by Renger-Patzsch in which we see New Objectivity photography at its peak. It has succeeded in turning abject poverty itself, by handling it in a modish, technically perfect way, into an object of enjoyment. For it is an economic function of photography to supply the masses, by modish processing, with matter which previously eluded mass consumption.

-- Walter Benjamin, lecture at the Institute for the Study of Fascism in Paris, 27th April 1934

> The relatively new trouble with mass society is perhaps even more serious, but not because of the masses themselves, but because this society is essentially a consumers’ society where leisure time is used no longer for self-perfection or acquisition of more social status, but for more and more consumption and more and more entertainment… To believe that such a society will become more “cultured” as time goes on and education has done its work, is, I think, a fatal mistake. The point is that a consumers’ society cannot possibly know how to take care of a world and the things which belong exclusively to the space of worldly appearances, because its central attitude toward all objects, the attitude of consumption, spells ruin to everything it touches.

In my experience all big cities i've been through are soulless, and so are the humans living there. When i say soulless, i mean people living there have: no sense of purpose, no community, no solidarity. Everyone has sold their soul to capitalist oppression and is just silently suffering their way to success or suicide.

Big cities require incredible quantities of concrete, and can't feed themselves. They are therefore NOT environmentally friendly at all (it's hard to think of something less eco-friendly). They appear to be on some stats because all the other ways of life (and local production everywhere) have been systematically attacked and almost destroyed by the "green revolution" and neoliberal policies.

If you want a city that's ecofriendly, it needs to produce most of its food locally (like Cuba) and use local materials for construction (clay-based earth is really good). That, and it should designed for pedestrians/bikes not cars. That's an eco-friendly city, but it wouldn't be high-density.

Although, i agree with you the suburban/countryside family delusion is no dream of mine ;)
'Catholic' does not neccessary refer to Roman Catholic and/or Christianity. See: https://en.wikipedia.org/wiki/Catholic_(term)
Culture evolves, and people increasingly question tradition for tradition's sake. Belief in God is at odds with a scientific view of the world, the decision to have children or not has many contributing factors (economic, for one), and it's hard to be patriotic when every country has so many skeletons in the closet you'd think it's perpetually Halloween.
I guess we disagree, since to me, serving ads with my page is making my position about wanting to show ads with the page pretty clear.

But even if it wasn't, Brave has special filters for sites that have anti-adblock measures, and it's spoofing the user agent to make it seem like regular Chrome.
>We might not know the reason, but the developer who did that had one and at the time it was probably a good and valid reason (and might still be).

People seem to assume every aspect of this forum has some brilliant, purposefully elegant rationale behind it, but the truth is PG designed the language (and the forum) to be experimented with and iterated upon, and likely didn't intend the forum to be considered "finished." This software isn't a masters' thesis, it's a proof of concept for a web application in Arc lisp.

Unfortunately, a cargo cult mentality has kind of grown up around this forum and every aspect of it is treated as sacred and not to be touched because "there must be a reason for it." The reason is probably that PG didn't care enough to iterate on the first working solution he came up with.
Have you ever been to Poland? The legal speed limit on the motorway is 140km/h, but 160km/h is more common, especially since there is effectively no fine for going that quickly, police are mostly interested in people going 200km/h+, because the fine for doing 160km/h would be like 100PLN(~$30/£20). I've driven my Mercedes-AMG some time ago through Germany and then through Poland, and yes, on the Autobahn I was able to hit 250-260km/h for maybe 4-5 minutes at the time(legally, which is amazing and I would 10/10 recommend to anyone who likes driving, scary as all hell though), but overal I can guarantee that my average speed was higher in Poland, the traffic is just moving a lot quicker and there's less roadworks compared to the autobahn.
