Regenerative braking improves efficiency even without careful driving, additionally you can drive carefully and improve your efficiency even more. This isn't the same as suggesting current regenerative braking isn't "good enough" for start stop applications.

I've never said it doesn't help. When the bar is in the right section, that means that your regenerative braking is operating at peak capacity, with extra friction braking applied on top.

> Braking will always involve energy loss, that's just physics. Over time we can improve how much energy is regained during braking but again that it can be better does not prove that it's not worthwhile now.

The energy loss of regenerative braking is some XY%. The energy loss of friction braking is 100%.

The optimal way to drive with regenerative braking is slow and steady braking. So that you are eating XY% energy loss in your braking energy, and not "Partially XY%, partially 100%". Most people drive in a way that would put them in the latter category.

As another poster mentioned, its quite possible for cars with $10,000 batteries to usefully absorb more energy through their regenerative braking.
If your goal is speed, you won't see significant gains.

Eric Normand explains it better than I could: https://lispcast.com/nil-punning/

In a nutshell, nil punning is a thing in lisps (and some other languages) where the null value can have different meanings in different contexts. It's comparable to Python's concept of "truthiness" and "falsiness", but more so.
I couldn't imagine someone being against a police Union and also supporting civilian unions. They serve the same purpose. I also can't imagine a sane person thinking we don't need the police, unless you're also supporting a highly armed population (which, I am.)

> With great power comes great responsibility, so the saying goes.

So you acknowledge that it's difficult, terrifying, unpopular and requires great reasonability, but offer nothing for a solution. What good is your comment?

The police job is more stress than any content moderator on social media, because the police are living the content that gets moderated. They're subjected to immense violence because average citizens need protection from criminals.

Once again, do you have any decent solution or do you plan to just add to the stress of this critical and thankless job?
It was big surprise to me that in a lot of European countries, it is possible to apply for passport by post
Stay Motivated When Feedback Is Scarce
Apparently nothing, but there is a correlation.

Here is what the article has to say about it.

If your date answers 'no'—i.e. is okay with bad grammar and spelling—the odds of him or her being at least moderately religious is slightly better than 2:1.

As someone who is not himself a believer, I found it rather heartening that tolerance, even on something trivial like this, correlated with belief in God, although I should've figured out that religious people are okay with small mistakes. Next to intelligent design, what's a couple typos?

It's also nice when two completely independent datasets corroborate each other. Last summer, we analyzed the profile text of half a million user profiles, comparing religion and writing-level. For every one of the faith-based belief systems listed, the people who were the least serious wrote at the highest level.

There isn't a shortage of generic developers, but there are shortages of specialized developers. One shortage example would be an SRE who knows Azure, Kubernetes, Jenkins, and Jira, very well. Another example would be a front-end developer who knows iOS development so well that they can make up for the pit-falls of React Native while also writing half decent typescript code.

It's often difficult to interview specialized developers because the specialist often understands (or pretends to understand) the specialty better then the interviewer themselves.

These hiring opportunities represent a large number (maybe even a majority) of roles at small, medium, and large, companies.

FANNG and maybe a few other companies which have custom tool chains from top to bottom are a little bit different because Google probably doesn't care if you know Jenkins because you'll have to be trained in their homegrown alternative anyways.
> When you say about the lack of documentation and get told that's a good thing, clojure is meant to be hard to learn, it's not for everyone and maybe you just aren't smart enough...

Clojure is not meant to be hard to learn and you are definitely smart enough. There are many, many learning resources for Clojure in every form and it has one of the most helpful communities I'm aware of on Clojurians slack, etc.
I really wish there was more work done in changing the terrible interview culture in software, instead of doubling-down on bad practices with low signal-to-noise ratios.

It's clear that whiteboarding and impromptu coding have little-to-nothing to do with real-life coding capability (let alone with generating real business value), while actual signals (e.g.: GitHub projects, OSS contributions, StackOverflow, take-homes, etc.) are ignored by interviewers. I've interviewed dozens of engineers and it's always been a miserable experience because my hiring manager (or other senior engineers on my team) always insisted on using these kinds of "grilling" methods which were never good signals to begin with.

It's a shame how our industry is the only highly-paid professional industry where this kind of sophomoric "intellectual hazing" is not only accepted, but also encouraged. I mean, hell, I have like three books on my bookshelf not about how to write good code, or scalable code, or performant code, but merely about how to pass interviews. Yuck.
I've used interviewing.io a lot and it has been immensely helpful. Not only did I get a lot better at interviewing, I also got a referral from the practice interviewer which eventually led me to my current job at a FAANG.
The hardware for existing geostationary consumer-grade (cheap, sub $150/month service) Ku and Ka-band VSAT terminals, for use in really remote locations in the USA, is about a $800 to $1200 cost. It's absorbed into 24/36 month contract terms.

People who live in a really remote plate and sign up for a 24 month term for some barely-usable VSAT service are usually disappointed to find out how firmly they're locked into the contract, when somebody builds a WISP in their area.

I would not be surprised if there's a terminal rental charge or 12/24/36 month contract terms offered.
Whoa. 12 for a pour over seems... strong. Now I'm really curious how I'll like microwaving those beans, since we seem to have very different tastes.

Libertarianism might have been the best fit

Fun fact: In Feynman's formative years, 'libertarian' still meant 'anarchist'.

I find it hard to keep off from mindlessly browsing the web.

It's become second nature to Ctrl+T and 'fa' for facebook, 'news' for HackerNews, 'red' for reddit, etc. that I barely notice I'm doing it.

It's a known issue that unrestricted commerce or indeed unrestricted ANYTHING is unacceptable because its trivial to imagine situations wherein an actor or actors can misuse the situation.

We cannot and shouldn't contemplate a solution to any and all possible feasible problems because time is finite and a solution that in theory results in the best outcome for a..z wherein h..z are hypothetical and a..h are actual may actually be a worse solution for a..g

The analogy is ridiculous on its face. It will never be actual. In such a situation we would trivially resolve it by passing a law that food stores can't blacklist groups of people while retaining the right to blacklist individuals for actual misbehavior. This would be somewhat limiting on the freedom of small shopkeepers to say throw out nazis but it would break the back of the "big food for lower taxes" coalition. Since none such exists this solution is as described above worse for the set of problems we actually have to solve a problem that is only hypothetical.

It would be more productive to discuss the ACTUAL issue by addressing it directly instead of trying to reason by analogy. It's not like its a topic people on this site have trouble understanding. Going off into the weeds like this just wasted time.
Yeah, see, when black people call cops they themselves get beat up by cops who show up after a few hours and arrest anyone they see for bothering them. So, more cops would hardly help. But if you can have civil cops that live in the community they protect,maybe that might help.

Regardless, I doubt you will ever get it. I think the rioters are holding back too much if you ask me. If I was in fear of my life from cops and I have exhaused the political process for decades like this people, I would be more strategic about the destruction, target gas stations, 18 wheelers, transformers,etc... Cripple the city's critical infrastructure. When they try to demonstrate peacefully ypu complain, when they democractically elect someone you fight undemocractically and in bad faith to prevent their success. People armed with automatic weapons stormed city halls just a few weeks ago with no consequence. Did you not see cops doing a drive by shooting? Cops marching and breakint car windows for no reason? Cops tear gasing a peacefup protest? Getting caught framing protesters so they can beat them up?

My friend, the rioting is for people like you so you can hear their screaming, I think they need to scream louder since you're still dismissing their plight as if they haven't been peacefully protesting and voting since the 1950's and the current president vowed to unleash vicious dogs on them, something JFK fought against in the late 50's and early 60's. So I think they need to scream louder this way so you can hear them.
Nah, I heard what you said and you said what you meant.

Even so, I'm happy to engage with your new argument: that regulatory capture is the first tool companies reach for to unfairly suppress competition. That's still wrong. Regulatory capture is slow, unwieldy, and opportunistic. The first tool a company reaches for is typically either M&A or dumping.

When WhatsApp was getting popular, did Facebook respond by crafting legislation with a plausibly deniable dual purpose, cultivating connections with campaign contributions and a held-open revolving door, wait for a wave of public sentiment that could carry their law up the priority list, through congress, and onto the books, and then sit back and pray that the resulting wind blowing at their backs and in WhatsApp's face would tip the balance enough to keep them on the throne? No, of course not! Facebook bought WhatsApp. Where there were two competitors, a free market exchange happened, and then there was one competitor. See also: banks. Yeah, they need FTC approval, but the free-er the M&A market, the easier it is for competitors to just merge together, and the more anti-competitive the result.

As for dumping, you'll often hear people blame legislation for the big ISP monopolies we have. Certainly there are no shortage of legislative failures in this space, yet it's not illegal to start an ISP. If you set out to create an ISP of your own, you'll probably be able to find a municipality willing to deal with you. The actual trouble will appear when you start selling your service. Your first few customers will gladly switch in order to take advantage of the better deal you're offering, but once the regional ISP monopoly notices the churn, suddenly you'll find that all of your prospective customers recently received a promotional discount from the monopoly and are no longer interested in your service. Then you go out of business, and customer rates go back up. It wasn't a law that kept you out of the market, it was the fact that your competitor had a larger war chest.

In both cases, more market freedom = less competition. Certainly, regulatory capture also exists and is also a problem, and in that case more market freedom = more competition. In some cases, it's even more complicated: economies of scale create genuine value by amortizing costs across volume, but they also create an anticompetitve moat. They have good aspects and bad aspects that are inextricably linked and inseparable from each other.

Still, focusing exclusively on regulatory capture will lead you to misdiagnose most markets. The cure will appear obvious, but where your diagnosis is incorrect, it won't work.
I think of interviewing like I think of other "tests" like the SATs. They're a thing you've got to study for. Just because they don't mirror what your day to day at a job will be like doesn't automatically mean they're of no value.

I think some coding interview questions are bad, some are better, but I don't think the idea that you must take what amounts to a test to get a job is inherently bad.

I don't think there's anything wrong with practicing interviewing. It can be a good exercise to do some self-reflection and, depending on the type of interview being practiced, can sometimes help prepare for real-world situations/challenges in a 'safe' environment.

Where I do think you're spot on is that you shouldn't focus all of your time practicing one specific type of interview or practicing for interviews at one specific company. FAANG is a good example. I've seen far too many people get enraptured with the "dream" of working at a FAANG, devoting all of their time to practicing FAANG-style interviews, making their whole life about it, and then either not getting the job or they do get the job but they quickly have their illusion shattered that FAANG isn't heaven and they wasted all that time preparing/fantasizing over something that isn't true. It's Paris Syndrome [0] but for jobs.

Sometimes, when the logic of a program is clear, J could be like a calculator for quickly getting a result. Actually, with J you're pretty soon at a point where you're refining the specification, not actually solving the problem (because solving is easy). There is a saying that an hour-long task APLer solves in 5 minutes and then spends the remaining 55 minutes refining the solution - and the problem - so they'd be clearer.

At some point J feels easier than other tools and it does feel like a "tool for thought" - a shorter way between what you think and what the program does. There can be even shorter ways, I don't know.
VMs? And to stay within the EULA you’d do this on Mac hardware of course.
I can't believe they thought it was that high. I mean general unemployment is no where near 27% and you'd suspect that with threat of losing visa status, immigrants are more likelier to take a job they dont exactly grok.

There is a similarity (if not identity) between the attitude of the writer of this article and that of a schizophrenic. She has created a world view that is internally consistent and that can accept no possibility of change from without (well, from a white person).

What is interesting and different (from the schizophrenic) is that this is actually good news for the writer. Reason is, as one schizophrenic told me, "If I don't tell anyone about the colored ping pong balls that are bouncing around the room then they don't know what i see and it doesn't bother them. All I need to do is keep quiet about it." She was doing well pursuing her college degree and raising her child.

IOW keeping quiet about (one might say accepting) one's problems allows one to live a more normal life. Its good advice for most anyone.
I doubt it. You seriously think police will go out of their way to look through these photos and arrest peaceful protesters?

On the other hand, in China, just for having Signal or the like on your phone is enough to earn a stay in their concentration camp and some involuntary organ donation before getting disappeared for good.

I would say there is at least a slight (very slight, mind you ;) difference between the two situations.
Well, sure, the Prius does not handle high-torque situations well. You're not going to be pulling a pickup truck out of the mud with it. It's not a great working car - you can't even jump-start another vehicle with it. That's an edge case for most drivers, though.

We also have information about what parts of the brain are responsible for what from examining functional loss resulting from injuries and tumors. It's all a bit messy because the boundaries are loose and things can develop differently for different people.
The typical design for a fusion power plant that runs on deuterium tritium fuel is to place a lithium "blanket" around the plasma. 80% of the energy released in the deutrium - tritium fusion reaction comes out in the energy of a neutron which would be absorbed in the blanket, heating it up and also generating tritium fuel which could then be fed back in as half of the fuel (the other half being deuterium which is abundant in seawater).

You would then run a heat exchanger from the hot lithium to create steam to then turn a turbine and make electricity.
You could even be ambitious enough to use multiple RTL-SDRs to do triangulation to the aircraft and see if it is where it says it is.

Alternatively, you could do passive radar with RTL-SDRs to perform the same verification and also to find aircraft that aren't identifying themselves with ADS-B.
As an American and a Texan, range bloat can definitely be a thing, but urban densities vary wildly in the US. My daily commute is on average ~30 miles round trip. But if I add a stop or two, that can quickly slew to 50-60 miles if I have to go downtown. And that's living relatively close to city center (~8mi outside downtown).

I had a Nissan Leaf and the range anxiety was real. I actually couldn't commute to downtown for work, and settled on taking my Leaf to a nearby Park & Ride and rode commuter bus line the rest of the way.

My wife drives a 2017 Volt now, and it's night & day compared to the Leaf. I'm personally ok with the trade-off of carrying a redundant power source for the convenience of never worrying about range again.

Aside from a couple of months where we had an issue with our Level 2 EVSE, we primarily use the battery on it. But it is also our road-trip car, given that our other vehicle is getting towards the realm of unreliable for long-distance driving.

While I wouldn't consider 200mi "local only", I would venture that anything under 100mi is, until destination charging is far more common. At least in the USA (outside the East & perhaps West coasts). Looking at multiple public charging maps, I can't get between Austin & San Antonio Texas without at least 100mi of range, and that's cutting it close.

The scale difference between USA & European countries is rather large, and most people can easily lose sight of that and make statements like 100mi is easily long-distance for Europeans, when most Americans would consider 100mi to be local. I've known people who's daily commute approaches that.

“Your "dream" job at a FAANG might be more unpleasant and boring than you've been expecting.”

The money can compensate for a lot of unpleasantness. I think finding a “dream job” is an illusion for most people. The question is usually “bearable” or “unbearable”.
To be fair, a passport is only needed to travel outside of the EU. Elderly that can't make it to an office to get the passport will have an even harder time actually travelling outside of the EU.

Because they've been asked to. And I expect that if there's hesitation, the survey runners ask them to give their best guess.

And if they don't guess, and move onto the next question, then they're eliminated from the aggregated results.

I feel the same. This really irks me. Obviously there are areas of building software where algorithms are a big deal. I recently was approached by a facebook recruiter(for android team) and amazon(can't recall the exact engineering position)...the facebook was even saying we will be asking some medium and a a few hard questions......literally ranked the same way as all the sites that people grind. I'm debating if I want to do it or not. Working at those companies can be beneficial for my resume but the interview process bothers me.
The fact that you can solve a problem does not mean you are a good software engineer. There is just so much more to development, architecture, oop, good team work and communication etc but maybe it is easier to teach those things than algorithms. Maybe this system works for the big companies. Plus, I think they are more likely to higher people who are obedient as people who simply won't put up with that hiring process might be more of a 'speak up' type.
