It's easy to dismiss this as green washing, but there is some value to it for city cars. The amount of electricity generated is never going to be enough to fully power the car, but that's not really the point. If having solar panels on your car roof means you can avoid charging much in summer, that will make owning an electric car for people who live in cities much simpler - and so support adoption.

As a back of the envelope calculation, if you covered the ~2.44 m2 roof of a VW ID3 with solar panels you'd probably see somewhere in the region of 244 kWh / year (based on typical UK solar panel generation per year - this would be more in a sunny place). At 4.3 miles/kWh that gives you just over 1000 miles / year of self charged driving.

It's true that those same solar panels would be more productive in a static installation. But it's also the case in the west that the biggest cost to solar rollout is installation, not the panels themselves. Putting panels on the roof of a car can be done in a factory, with none of the tricky site-specific work that makes costs balloon.

In fact, Hyundai are already planning a solar roof option with their Ioniq 5 (https://interestingengineering.com/hyundai-unveils-charger-o...). It will be interesting to see if that has any impact for the typical driver.
SMS has no security at all.

SMS is not properly encrypted over the air, GSM and UMTS encryption is broken and often misconfigured anyways. There is no way to check and no guarantee that a SMS will be transmitted in a safe encryption protocol, i.e. no way to force LTE. And given the level of brokenness in GSM and UMTS, I wouldn't rely too much on LTE or 5G crypto being worth anything. End-to-end encryption isn't provided anyways.

Also, phone numbers are not terribly secure either. The control protocol for mobile networks, SS7, is a steaming heap of excrement without any consideration for security. There are numerous ways to redirect SMS and calls into the hands of criminals, which have been demonstrated over and over by researchers. Also, this is regularly being abused by the police, secret services and criminals. As a customer, you are completely at the mercy of the phone network to do the proper mitigation dance because SS7 is inherently broken and cannot be fixed, just maybe firewalled off (a little, but not too much...): https://attack.mitre.org/techniques/T1449/

Then there is a whole lot of social engineering cases to take over numbers and SIM cards which others have described nearby.

With 2FA via a proper app or even open protocols like TOTP, I can verify and trust much more of the auth flow. Properly done, I only need to trust the endpoints and (maybe, if used, with TOTP even that is unnecessary) the TLS connection. With SMS, I need to trust a whole lot of telcos between the endpoints, their firewalls, IDSs, (mis-)configurations, all their service providers and their employees not to fiddle with things. And actually, all of the aforementioned have repeatedly proven untrustworthy by using broken, outdated, and known-to-be-insecure technology.
I used to hate on Flash in favor of the grand unifying standard that was HTML5 and JavaScript. Turns out we just exchanged one monopoly by another. And Flash actually enabled artists to do games and shit, as opposed to the idiosyncratic HTML/CSS scene graph attempts, canvas, WebGL, and audio/video sync crap still not matching Flash. Certainly, the web with Flash was more creative and fun.

You're right that we used what we learned from Scalar's background maintenance an applied that to Git itself.

Putting background maintenance into Git was actually part of our effort to get Scalar on Linux.

You might be interested in our "Philosophy of Scalar" [1] document, which includes this paragraph:

> Scalar intends to do very little more than the standard Git client. We actively implement new features into Git instead of Scalar, then update Scalar only to configure those new settings. In particular, we are porting features like background maintenance to Git to make Scalar simpler and make Git more powerful.

Well, you conceded that it's primarily a winterisation problem, but then immediately say:

> ... but having so much capacity invested in unreliable wind generation was a very significant contributor to the blackouts that should not be ignored.

The word 'unreliable' is ambiguous here -- clearly world+dog understands that power generated by wind is highly variable, and ERCOT (as for any ISO, and similar orgs in other countries) maintains and improves their forecasts around this variability.

This is factored into the overall grid provisioning and maintenance of power to consumers. It's why I asked about the effect of this variability outside of major cold events. Evidently not so much?

So, using the word 'unreliable' in a way that sounds like wind turbines can't be trusted seems disingenuous, since there's no surprises with the way they operate, and the variability in the power they can generate.

Your comment that billions should have been invested in anything except wind, and this would have guaranteed significantly more electricity available - isn't supported by the facts. Nuclear, gas, and coal all failed in various but predictable ways.

So you're kind of conceding that winterisation would have helped, but only in the context of fewer wind turbines being taken out. The fact coal, gas, and nuclear failed, because they hadn't been properly protected against cold weather, you seem to be discounting.

I haven't stared at the ERCOT numbers, and am disinclined to do so -- the fact that much of the state was without power for several days, and early reports suggested the grid was some minutes away from catastrophic cascading failure, suggests to me that concise numbers aren't the important thing here.

What's clear is that despite the 2011 heads-up, and the audit two years ago that highlighted the continued lack of preparedness, it was way more than the predictable freezing of some wind turbines. The history and political motivation for this highly isolated ISO further highlights the problems of poor planning and poor regulation. Were they not so intentionally disconnected, power could have easily been sourced from elsewhere in the country.

I did find an interesting 'actual number' that their lack of maintenance for their wind turbines was a major contributory factor:

"Though frozen wind turbines were a contributing factor, wind shutdowns accounted for less than 13% of the outages, Dan Woodfin, senior director of system operations for ERCOT, told Bloomberg." [0]

Further in that article:

"According to a report from ERCOT, solar accounts for only 3.8% of the state's power capacity throughout the year. Wind energy accounts for 10% of Texas's winter energy capacity and throughout the entire year it is able to provide 24.8%, the second-largest source of energy in the state under natural gas, which accounts for 51%."

Which suggests your 25% figure is misleading, as that's a yearly average - it's 10% (about the same as nuclear) during that time of year.

You could easily do that in the USA as well. Median income is $35K and that’s before taxes and without a corporate shell to transform some of the larger living expenses into corporate pre-tax deductions.

Once you have JIT public transport then there's no difference really
The good thing about SMS is that it's standard. I live in Sweden, just about everyone has a smartphone. SMS is still common for things like package delivery notifications or other service notifications, SMS is still an option for many transport tickets, though being phased out in favor of app solutions.

SMS works whether you're on iOS or Android, it works for the few users of classic phones, it works if you don't currently have mobile data, etc. It's not a secure method of communication and has other flaws, but it's the most reliable one if you don't know anything about the recipient. Whether they're using their beloved Siemens S35 or the latest Android flagship, they can receive a SMS.

It is a valid point, that should be taken into consideration in the discussions on the topic, but it doesn't validate the original argument.

The proponent of the "reversed argument" may argue, that, even if we can't ban alcohol (a real shame in their opinion), we shouldn't damage the situation any further with another evil substance. Later we may find that the new substance becomes "unbannable" as alcohol.

That's a fair point. We need to setup some examples with mock API calls so we can offer a consistent state to all new visitors. In the meantime, here is a quick demo - https://codesandbox.io/s/elastic-northcutt-9pcgv

The app does work by the way.

It is a steaming hot pile of garbage where the government has yet again decided to not use a widely accepted standard.

But if you just need to login to myGov every few months to check something or do your tax return it works better then the SMS

(Just don't lose the phone it is installed on, because you can't link it to a new one without ringing and wading through security checks)
That's fair enough, and I agree, people can be very reluctant on that front.

It goes against a lot of conditioning that drugs are just plain bad, and it appears to contradict their lived experience in which they don't think they've really had an issue with alcohol so it must be OK. Not like those other things where people get addicted and get into all sorts of trouble. It's just a beer. Never mind aunt Theresa who died falling down the stairs, drunk as a skunk, at the age of 40 because her cirrhotic liver just burst like an overripe melon when she hit the bottom step. Or your friend's mum who they're not on speaking terms with because she put her drinking habit ahead of feeding her kids when she was young. If anything that just adds to the conviction that drugs must be so much worse, because drugs are bad, and this is 'just' a beer.

Personally I have a complex relationship with alcohol. I brew at home but I'm not blind to the damage it's done to me (thankfully just some pretty bad hangovers and behaving like an arse from time to time, well, and the belly) or to others.

Yes, all those people are delluded.
The hardest thing about implementing notifications for me is not the UI, it’s the rate limiting (avoid bombarding users with duplicates), intelligently handling state changes, and figuring out when to escalate to an email/sms channel. The homepage doesn’t convince they’ve solved the hard problems surrounding notifications.

A laptop is a must-have along with external monitor/keyboard. Whether they are under-powered really depends on the tasks you perform and more powerful compute resources may be accessed remotely if needed.
The other 2 of 3 benefit from the torrential inflows of capital, and if one of them produces some clever engineering then perhaps it's a net win overall for society.
Which is something that I'm surprised doesn't exist on more ICE vehicles as well. Gone would be the days of dead lead acid batteries and parasitic draws if ICE vehicles would stick some solar panels in the roof and/or hood.
what's the problem? Apart of a fact that you have to pay them
SMS is fine for 2FA for Reddit. It's not fine when it protects things that have financial repercussions. But that's when we actually need strong 2FA.

It's been proven time and again that cyber criminals frequently target people using SMS 2FA to steal from them. Most implementations of 2FA might as well be 1FA. People might even use worse passwords when they think 2FA protects them.

I think the adoption of SMS as a "universal 2FA" was not worth it. We should've just gotten people used to the less easy but more secure methods. U2F bluetooth keyfob on my keychain would be good enough for my phone and PC. Remote access seems like the hardest nut to crack.
I know what you meant, but with those words I hinted, that the decision from Rockstar was likely more a move out of PR motivation, not moral standards, that you assumed.
Ask HN: Machine Learning and Materials Science?
Hello! Is anyone here doing some research blending these two subjects?

I had my degree in materials science and engineering long ago (2013) so I have a huge gap of what's going on today.

I'm enrolled now in a master's program in computer science and I'm thinking about relate both topics in my research.

In my daily job I work with python and machine learning (ecommerce tho), so i have some foundations.

I just wanted to know where should I start looking at and exchange ideas with people doing the same kind of research.

Thanks HN!

iFixit sells the tools to do so and provides detailed guides on how to use them.

It might sound like a racket to you, but at this point they've saved me something like half a grand net, minimum, on phone repair and replacement, by making it possible for me to do that work myself and thus not have to replace phones nearly so often.

Most recently, this came in useful when I actually did drop a phone in water, just like we're talking about here, and was able to not only clean it out but also replace the battery, which swelled quite alarmingly in the aftermath.

We handle state changes (and sync them real-time). We'll get to rate limiting and other features you mentioned in the coming months. We have a pretty extensive roadmap and would love to keep you posted - @magicbell_io.
Some countries resolve the porting issue by having a list of numbers that have been ported, so that banks (for example) can check that and not rely on it if the port happened in the past two weeks (also, for example.)
SMS 2f is only used to collect phone numbers. There is already an open standard called TOTP that people can use, and which requires no special access and isn't locked to any PII.
Because if you use HTTP caching, you can use a CDN with 100s of global locations. Which is quite a bit more powerful than any custom solution.

Sort of, but not entirely:

- As Papers without Code website presented: many algorithms in papers are manually super-optimized to perform state-of-the-art on benchmarks

- Much of ML work outside of top academia and FAANG lacks rigour or doesn't compare results with "dumb" baselines.

- Many companies (e.g. Google, FB) have not devised a proper recourse procedure for mistakes their "AI" policing bots make (and WILL always make).

However:

- Weren't it for commercialization of ML, we would not have ML accelerators of some sort in almost all modern hardware.

I agree with this.

The net grid draw of EVs would decrease if every EV were equipped with solar panels. It's a way of turning the footprint of the car into a source of energy. Not sure how the manufacturing costs work out, but you don't have to replace 100% of the plug-in aspect to substantially reduce the energy costs.

>No you cannot, you cannot infinitely scale SQLite, you can’t load 100 G of data into a single SQLite file in any meaningful amount of time. Then try creating an index on it and cry.

Yes, you can. Without indexes to slow you down (you can create them afterwards), it isn't even much different than any other DB, if not faster.

>Even Postgres by itself was very hard!

Probably depends on your setup. I've worked with multi-TB sized Postgres single databases (heck, we had 100GB in a single table without partitions). Then again the machine had TB sized RAM.

Exactly that. The situation has reversed completely compared to 10 years ago. From there we have "innovations" like the BMW i3 which seems to be exclusively used by their own car rental company because it's not a feasible product by itself.
Beanie – MongoDB ODM
I've observed a related issue with much amusement for a few years now: when loading a new resource (specifically: spinner going anticlockwise, waiting for TTFB), Chrome will invisibly switch the renderer over to the font size settings of the to-be-loaded resource, then carefully inhibit repainting the view.

But, if said destination resource is very slow to hit TTFB, you switch to a different tab, then back to the loading tab, you'll see the current page at the destination page's zoom settings.

My guess is that the interstitial system that injects error pages, Safe Browsing warnings, etc, doesn't hit the code path that says "we loaded a new (regular) page, go find its zoom settings".

Demo/PoC:

1. Run $anything that will serve a webpage on an arbitrary port - even an error page or directory listing. eg, python3 -m http.server, php -S 0:8000, etc.

2. Open the resource you just set up in a new tab, zoom in or out as preferred (eg, to a crazy level), copy the URL (for convenience), then close the tab.

3. Stop the server in (1), then run `nc -lp 8000` (or netcat, ncat, or $anything that will listen but never respond).

4. Open a new tab, navigate to a valid website (eg here :), example.com, etc), then once it's loaded, paste the URL you copied. With the page spinning and waiting for netcat (et al), navigate away from the tab, then back to it again.

Think I noticed this for the first time a couple years ago. Seems harmless enough.

The owner would be the landlord, there is no benefit to them installing solar panels unless it increases the rental value to pay for them, it likely doesn't.
