It will be worth taking a snapshot of a Sunday via https://www.londonair.org.uk/LondonAir/nowcast.aspx and comparing to the no car day.

It's a shame a week day was not selected, but it would be a bigger shame to have this be a once a year promotional day rather than part of a learning exercise towards reduced pollution in London.

Another link of note would be https://cleanair.london/ which brings together many of the resources that document the current air quality and either proposes or tracks the policies that may address it.

While I agree that the method is pretty bad, I think the video is about as top notch as it could have been given the reset method choice.

You’re meant to use the video at the same time as you’re performing the reset, and it gives you a timer to help out. Also, the changes are synced with the moments he says “on” or “off.”
your comment lead me to take a look and I have to say I agree. it looks denser but feels more cryptic. sure hope it remains optional.

I’ve personally abandoned plans to purchase because it wasn’t clear if I would get a chance to review at the end. Its especially important if its unclear what the final price will be, after applying shipping and such, since I live outside the US. Anecdotally, I’m much more likely to buy if its very clearly stated that there is a review step.

I know that more impatient people might be the opposite way around, though.

Here is a good article showing thermal and mechanical fatigue. You can see under moderate mechanical stress, it fails between 1e5 and 1e7 cycles. While that sounds like a lot, consider that there are 3e7 seconds in a year.

So if you had a mechanical device that operated at 1HZ, it would fail in less than a year.

I wonder if there’s no way of making frames work. It seems like such a waste to have the same HTML code for navigation on every single file.
I totally understand that this works for you — and like I said, I’m not discounting this as a fun thing to do.

But I guess my broader point is that if I have to create a shell script to quickly generate the boilerplate file stuff for a new post/page, I’m _basically_ already doing what early PHP was designed to do. And at a certain point (and again, I’m not talking about you specifically, just the movements around this so-called simplicity more generally), we’re reinventing stuff that was literally created 25 years ago for these very reasons.

I’m hardly innocent of this either. As much as I hate them, I fantasize about and start working on a new CMS or SSG at least twice a year, only to inevitably abandon my efforts once boredom/frustration sets in.

If I recall my high school biology correctly, the strict definition also has the requirement that the offspring are able to reproduce themselves (hence making donkeys and horses separate species).

The article mentions no evidence that in this case the hybrid was able to reproduce, since it's all based on the analysis of only one skull.

Sure they can. There might for example be sales people who are operating in countries where bribes are common and despite clearly stated no bribes policies they will still bribe or behave unethically to win deals and further their career/compensation.

If it is reasonable to think that the leadership should have known about it then sure they can be blamed as well but often that is not something that is reasonable to expect.

My desktop caught fire once. I pulled the plug and the fire went out. Turns out the graphics card burst into flames. That had never happened to me before in 40 years of desktops.

Cool stuff, and I didn't mean to discourage you at all. Some of the most interesting challenges in datascience arise in finance.

Forex perhaps is just a pathologically tricky beast to trade well, even though it is the easiest to access. I think perhaps cryptos would be an easier start in terms of there being more inefficiencies and autocorrelation in the market.

In terms of data treatment, I recommend starting with Marco de Prado's Advances in Financial ML. I don't agree with some of his methods, but it is a practical book that highlights a lot of the issues you'll face. You can then draw your own conclusion how to treat them.

Even further back than 3 years. They previously used to even allow you to edit the underlying map, business and road data in a nifty UI kind of what OSM does now. That was a good 5 years ago I think.

I find that to be very unlikely. Batteries are known to have failure modes that include explosion. It’s certainly not unique to this laptop, or even laptops alone. This is the only case I’ve heard about and it’s a 4year old laptop that had been repaired.

"I'm losing my perspicacity!"
It was my understanding that the “specific purpose” had to be “the technical functioning of the site or service” (and also any transactional mail, like sending order receipts), not literally any specific purpose. Selling your details to the highest bidder is a specific purpose after all.

If the company calling you back isn’t unsolicited (ie I asked them to or they told me they would and I said OK), then its an expected part of the interaction. Cart abandonment emails are not expected or even necessary (from the customers point of view). If I called a company and they called me back days later, without telling me they would or asking if I mind, I would absolutely report them for that too. (At least in my country, data protection says they can’t do this)

Cart abandonment is just like any other marketing and honestly, I report any cart abandonment emails I receive as GDPR violations to my local data protection commission.

In my opinion the title of the original paper is much better, in that it's not clickbait. It's "Room-temperature Operation of Low-voltage, Non-volatile, Compound-semiconductor Memory Cells"

And it's here:

https://www.nature.com/articles/s41598-019-45370-1

Moreover the abstract is probably a better foundation to base discussion on:

Whilst the different forms of conventional (charge-based) memories are well suited to their individual roles in computers and other electronic devices, flaws in their properties mean that intensive research into alternative, or emerging, memories continues. In particular, the goal of simultaneously achieving the contradictory requirements of non-volatility and fast, low-voltage (low-energy) switching has proved challenging. Here, we report an oxide-free, floating-gate memory cell based on III-V semiconductor heterostructures with a junctionless channel and non-destructive read of the stored data. Non-volatile data retention of at least 104 s in combination with switching at ≤2.6 V is achieved by use of the extraordinary 2.1 eV conduction band offsets of InAs/AlSb and a triple-barrier resonant tunnelling structure. The combination of low-voltage operation and small capacitance implies intrinsic switching energy per unit area that is 100 and 1000 times smaller than dynamic random access memory and Flash respectively. The device may thus be considered as a new emerging memory with considerable potential.

With all that out of the way, I find new memory tech to be one of the interesting niches of IT R&D going on today. So I hope this winds up going further.
Depends on what you're interested in, your goals and your starting point. You have two main learning lanes:

1. Theory.

Math, calculus, linear algebra, probability, statistics, ML algorithms. ISLR is a very good beginner-ish resource that helps you understand the algorithms but doesn't go too deep into the math. As you go deeper, you may realise that you have gaps in your math knowledge and you need to cover a lot more probability, calculus and linear algebra.

2. Programming.

2.1. Good software engineering practices - writing maintainable code, design patters, version control, unit testing etc.

2.2. Tooling - knowing the language-specific ecosystem of libraries (the OP is an attempt to teach you this in two languages at the same time). This is what most beginner resources focus on; your knowledge here has the least transferability and tends to go out of date quickly. Still, using the right tools and knowing them well goes a long way.
Ask HN: What are you doing to 'chill off' during work?
Hey HN fellows, what are you doing when your head became hot from working, so you can stay productive?

This is my routine in order to not get burned:
- Daily meditation (relaxation)
- Play games up to 30 min per day (fun)
- Take 15-30 minutes walk during the work
- Big tasks diversification

Other things:
- Exercise daily (at least a stretch)
- Turn off mobile notifications from 7pm to 7am
- Get offline during the weekends and spend time in nature
- Eat healthy so I can digest better and not spend too much energy on digesting
- Sleep between 11pm and 6am

I would love to hear something unusual, but effective too :)
As someone who previously worked in ecommerce marketing, many of these practices certainly would cause more drop-off in the funnel.

I would suggest that the idea is that losing X% of first-time customers isn't such a big deal if you can increase LTV by Y% through marketing efforts otherwise not available to you.

That being said I don't really think the average marketing team has thought it through to this point (or measures the outcomes). But nevertheless it's perhaps why they see positive results.
No, it is punishing the wrong people, who would lose their jobs and who were not the ones responsible for the decision making.

A. Who is "you folk"?

B. Sure, the samurai lost their political power by the Meji period. That doesn't mean their social and cultural influence disappeared overnight, especially since the country spent decades more or less under the thumb of the Imperial Japanese Army....who saw themselves as carrying on the samurai legacy, well within living memory for some Japanese. In the 30's and 40's it permeated the school system, so generations of Japanese grew up with that same military discipline, inherited from the IJA, who inherited it from the samurai.

They sure as hell didn't get rigid selflessness and tolerance for suffering from rich merchants. Plus they still form up for morning PT sessions at corporate jobs! They just have the intensity dialed down to.....1/10. Do you ever see this in any culture that hasn't had a strong military tradition?

> This is a straw man argument.

That would imply ill intent on my part, and there was nothing of the sort. All I said was that I couldn't see the sense in certain things and, without further explanation, I didn't. Other comments helpfully pointed out the context for why the assertion is so often made and I was happy with it.

On the other hand, I think I'd need to see some hard evidence for the following assertions:

> When the types are complicated enough, people no longer read them

What is a complicated type?

> As the person writing the code, figuring out what the types actually are and writing them down doesn't actually help anyone.

Citation needed. I find static typing tremendously helpful in my own code, especially if it's code I haven't worked on in a long while.

> It's just busy work that the compiler or interpreter could have inferred

… such that I only notice errors when the code is running, not beforehand. Without type annotations, interpreted languages like Python and Ruby are happy to let wrong types in function calls and message passes slide — which is why frameworks like Sorbet exist, to help eliminate that class of error.

> 2.

All of that is language-specific, surely, not really anything to do with static or dynamic typing. That whole mechanism is quite straight-forward and has a well-prescribed mechanism in Swift, for instance, with protocols, extensions, and conditional conformance.

> OTOH, in a dynamic language, all of that work is just gone.

I mean, it's not just gone. There are trade-offs, of course there are; but the assertion that the work is gone also implies the potential associated errors are gone seems a bit ingenuous to my eyes.

Yeah, types can be a bit constraining — but at the same time, if you reason about them properly and according to the language's prescribed mechanism rather than fight them, it can and does become second nature. At that point, using types becomes as simple for some as not using types is for others.

I number of plastic items I have from the 60's to 90's have degraded. The plastic has become brittle and has taken on an ugly yellowish hue.

As this Vox article explains[1], if rent is taxed but imputed rent is not, then a homeowner would pay no tax, but if he and his neighbor decided to rent their house to each other (with zero net change in income after rent), then he would pay the tax as a landlord. The decision to exclude imputed rent in US Income Taxes was apparently a decision of the Treasury in designing the first Form 1040 for 1913 despite economists’ arguments for including it in the tax[2].

In US income taxes, the inequality exists to this day. Owner-occupiers get to keep their rental income without paying taxes that landlords would have to pay (though landlords get to deduct maintenance), in effect taxing poorer renters at a higher rate than wealthier homeowners. When someone buys a house instead of renting, he gets an implicit tax deduction on the imputed rent that renters+landlords aren’t allowed to take.

So if we were to design a tax on hoarding scarce land, logically we would want to avoid the mistake that the US Treasury made in 1914, and include vacant landowners, rentiers, and homeowners in the same bucket. A normal property tax according to value gets this right by treating them all the same.

All we know is that there's one incident, and now there is a recall. If there was no endemic issue, there should not reasonably be a recall; there's been handfuls of stories about iPhones burning up that have not ended up resulting in recalls, presumably because they're isolated issues.

I don't actually know how many Note 7's burnt up before they recalled, but I don't think it was ever very many. The main difference in this case is whatever issue exists, it was relatively benign for at least four years, which I agree hints that the issue is far less severe. But of course, no less dangerous.

It's interesting that Melville was seen as derivative during his latter years, when he was in fact creating his own aesthetics and rythm (a Sergio Leone of film noir, if you will).

For people fans of his style, I can only recommend the work of Johnnie To (and that of his film company, Milkyway Image), in particular The Mission, PTU, and Exiled. Few settings are more Melvillian than Hong Kong by night.
> I hope Apple finally fixes the Keyboard+durability issues with their next MBP iteration. Personally, I came to think that the 500$ Apple tax is worth it compared to all the (software) convenience + (hardware) quality that they offer.

I agree, I bought the X1-e as the replacement of my rMBP because I just couldn't live with the keyboard and the touchbar of the new MBP. But the experience of the X1 didn't live up to it's expectations, mostly on the software side.

Don't get met wrong though, the X1 is a great piece of hardware. The keyboard is awesome and I really like upgradability.
But the experience on Windows (or Linux for that matter) is just not so good. A macbook is just more polished, and that is coming from someone who generally doesn't like Apple products.

In the end, this is a work laptop for me, and I just want stuff to work. And for that, the $500 Apple tax is worth it.
Every time I have to buy or use something with unnecessary plastic in it I just feel extreme disgust. There's just too much plastic around us that it would take decades to recycle or decompose them even if we discover the way to do that right now.

First rule of engineering I learnt was: there are always trade-offs. You can't have it both ways. You're right, plastic is cheap, lightweight, resistant, etc. But shouldn't we have asked: "Ok, but what's the catch?"
