Mopeds are step-through primarily to allow room for the engine under the footrest or above the rear wheel. For the same reason they have small tires and relatively high rake angles. In a lot of ways that's a straight downgrade: it makes the handling much less stable (which is why rake must be high), it makes the frame weaker (so it is constructed heavily to compensate) and it makes ride quality worse.

Electric motors and batteries have very flexible envelopes so you can fit a very powerful powertrain in a bike with no problem- the battery just has to be very skinny. The big wheels and responsive handling mean slow speeds are very controllable compared to a moped, and the handling and bike weight is much lighter.

What I think is really needed is an e-bike that is meant to be an actual road vehicle, IMO specifically that has a lot in common with a motorycle. Something with a much larger battery, streamlined wheels, a headlight and turn signals, and a comfortable seat. That would be just lovely. I still strongly feel that having a scooter form factor is not necessary to have those things, though. For instance the Haibike Xduro Trekking Pro[1] managed 32 mph and claims 30 miles range, but that's with pedaling (the bike provides 275% boost power). It also has front and rear lights, but no turn signals. Pretty good 51 lbs,and the frame looks like it's extra low to facilitate picking it up. Still, I wasn't able to find anything that provides the weight/power/range of an e-bike with the features of a motorcycle.

Ask HN: Looking for a career change from IT, where to start?
I feel burnt out and overall I don't really feel passionate about IT anymore. I'm looking to switch careers to a more people-centric job, like a salesman or real estate agent or similar, but I have absolutely no idea where to start, given that I have zero experience in the fields I'm targeting - I've only ever been a developer.

Anyone here did something similar? Any tips you can give me? Thanks.

Whoa, for a moment I felt pretty sure you would be mistaken. Hadn't read about this particular vulnerability before.
Some of us are just tired of people who don't respect the people and work that came before them.

There was a guy at the second-to-last place I worked who didn't know who Alan Kay was! What's worse, he wasn't ashamed of his ignorance.

At the last place I worked someone was refurbishing an old "expert system" written in CLIPS [1], he asked my advice and I said, "Consider using Prolog." He said, "What's Prolog?"

These are guys getting paid six figures and they do not care to educate themselves on the background of their chosen field. It's lame.

California is in the wrong here: https://www.pillsburylaw.com/en/news-and-insights/hyatt-to-m....

Basically, California contends that this guy owes taxes for 1991-1992 because was still a California resident at that time, despite extensive evidence he changed his residence to Nevada before the relevant date:

> During the audit, Hyatt provided FTB with evidence that he had rented an apartment in Nevada, obtained a Nevada driver’s license, opened a Nevada bank account, registered to vote in Nevada, obtained Nevada automobile and renter’s insurance, joined a Nevada synagogue, and sold his California home prior to the date of his asserted residency change. Nevertheless, FTB concluded that Hyatt staged the alleged move to Nevada all in an effort to avoid state income tax liability on his patent licensing income.

In the process, the FTB conducted an abusive investigation:

> FTB conducted interviews and collected signed statements from various individuals who were estranged from Hyatt at the time, but ignored witnesses with whom Hyatt had good relations. FTB auditors allegedly rifled through Hyatt’s mail and garbage, and made anti-Semitic remarks in reference to Hyatt.

Hyatt sued the FTB in Nevada courts. The FTB then invoked California law, which provides it immunity from suit. The Nevada Supreme Court held that the FTB could not invoke California immunity from suit in a Nevada court. The U.S. Supreme Court agreed, holding that the FTB was entitled to no more protection than a Nevada State agency would receive in a Nevada court.

Hyatt then won almost $500 million at trial against the FTB on tort and fraud claims.

California appealed, arguing that Hyatt couldn't win a judgment against the FTB in a Nevada court that exceeded what he could win against a Nevada agency ($50,000). In a real "live by the sword, die by the sword" ruling, the U.S. Supreme Court agreed, knocking his judgment down to $50,000.
Why is the govt spending $25M on a case, that if it wins, would result in a $13-55M payout?

So YOU and me learn. CA will leave no stone unturned to get their money...
I think that would set a terrible precedent that your tax obligation is equal to your legal team costs to drown the government in paperwork or actual tax liability, which ever is lower.

We actually now understand that passing control to a human is seriously dangerous - unless you can do it a minute or so in advance, the human has to switch context from being a passive passenger (or, more likely, actively engrossed in something else) into being an active driver very quickly. Everything up to level 4 automation will cause accidents when the car attempts to hand control to a human.

Of course, there's a very reasonable argument that e.g. level 3 automation might cause fewer accidents overall, even if it kills people when it has no idea what to do, but convincing Joe Public that such a car with such a known flaw is safe is another matter.

LispWorks can:

* save images

* create optimized images/applications for delivery, using a treeshaker for removing unused stuff

* can generate Mac applications with the usual ceremony/ application bundles

* can generate shared libraries which can be linked into programs written in C or similar

Some other compilers can generate standalone C code doing whole-program compilation. For example mocl or some inhouse compilers used by companies.

The photos themselves aren't locked in: they end up somewhere on your filesystem (that mimics the structure you see in LR).
It's only the metadata and other photo edits that you would lose if you were to stop subscribing. And of course you could export those edits out of LR before you stop your subscription.

It's not much different from another piece of software that you buy outright, but that is not going to be supported after X years. You'll have the same problem: "hey photo_something 2.0 doesn't work on MacOS High Sierra anymore, but our v3.0 does, for a small upgrade fee".

Are you going to hold back on upgrading your OS? For how long? At some point all the delay tactics stop working, and by then there isn't enough of an ecosystem for the "old world" anymore to help you transition out smoothly.

$120/year is really not that much if you are a professional photographer (or digital artist) who needs the bells and whistles that PS/LR provide. If $10/month makes or breaks your business, I have bad news for you.

I personally think that $10/mo for LR/PS is a great deal.
C# 7.0 already has the 'is' pattern matching operator that returns true/false and can introduce a new variable that is not null.

Ok, so you have indeed changed syntax. Saying that Haskell/ML-style function application syntax is consistent with juxtaposition for multiplication is in no way inconsistent with anything I have said so far. Remember, you used "gravitationalAttraction(mass1, mass2, radius)" in your very first example, and I am speaking to the difficulties getting that example to work.

When I said "it is at odds with juxtaposition for multiplication," I meant "having Haskell/ML-style function application along with classical function application notation", given your original example.

There is nothing controversial with the statement "if you are allowed to change the notation for function application, then you can add juxtaposition for multiplication in a consistent way." But I feel this goes against your design goal of "writ[ing] multiplication naturally." That's not to say we can't come to see Haskell/ML-style function application as natural, but it is not yet the mathematical syntax people learn in school.

>>Recall, I said "tends not to". My point was that the notation of mathematics is set up to prefer the case of functions returning values.

>Functions are values...

Either I missed something basic, or I actually meant something about how mathematicians think about the objects of their work. It is extremely rare to see the functions returned by functions being used immediately as functions. They'd rather either use subscripts like

F_t(v)

or use a pairing between spaces.

In abstract algebra, it's common to see fgx to mean f(g(x)) when f,g are in a ring R and x is in an R-module. With Rtimes being the multiplication in R and App being application, fgx is interpreted as both App(Rtimes(f,g),x) and App(f,App(g,x)), since they must be equal. Mathematicians would be surprised at the interpretation App(App(f,g),x).

> I think it's pretty obviously unreasonable. In any reasonable language:

Yes, you can make consistent systems where it is unreasonable, but that doesn't mean that there is no system in which it can be a reasonable interpretation. I didn't just make that interpretation up: things like e^A where A is a square matrix come up frequently in the study of differential equations, and it is interpreted by substituting A into a power series for e^x.

How does this work remotely? Do you actively ping people on IM and ask about their everyday life? Do you send out emails? Do you do it over meetings/videoconference?

I find that extremely hard to happen remotely as opposed in person because I never know when somebody is in the zone or not and I don't want to actively distract them with "useless chatter" for no reason. I know people who get very annoyed by these constant interrupts and I'd also find that very hard to judge remotely, I wouldn't want to become "that guy" and not even know it.

Sorry for that, I just want to "show" my idea and to see how people think about it, for more detail please take a look at my reply to `sova`.
Liking someone does not necessarily mean that working with them will make for a good experience. Human relationships are complicated.

I had some experiences working with the guy that were good in some ways and bad in others. The bad parts might have been his fault, or my fault, or both, or might have been because of environmental things that neither of us controlled. There's a good chance that they were caused by a combination of such factors. As always, it's hard to be sure.

He approached me when I was at NeXT. He wanted me to work for his startup. I had reservations. I thought there was a fair chance that it would go badly because of the bad things from before. On the other hand, I still liked him and I wanted my reservations to be unfounded.

They weren't. In fact, it was worse than I feared.

The language I was referring to was the version of Dylan that the bauhaus project used for our OS work. It was basically Scheme plus CLOS plus some functional-programming extensions, and a type system in which all datatypes were CLOS classes.

The development environment, named "Leibniz", was a greatly-extended version of Macintosh Common Lisp that included both the Common Lisp compiler (whose output ran on the Mac 68K-family processors and which was used to implement the whole development environment, including the Dylan compiler) and also the Dylan compiler and runtime, which was initially written for AT&T's Hobbit chips and later ran on ARM.

When bauhaus started our development machines were Mac IIfx boxes with great big Nubus cards sticking out the top. Later they were actual working Newton hardware ribbon-cabled to daughterboards in the Nubus slots.

Leibniz had two sets of everything: one for Common Lisp and one for Dylan. You'd think it would be confusing, but it wasn't, not after the first day or so. There were Common Lisp editor windows and Dylan editor windows. There were Common Lisp Listener windows and Dylan Listener windows. And so on.

That's still my favorite programming language.

I liked the development environment, too, but my favorite development environment ever was SK8, Apple's HyperCard-on-steroids-with-a-built-in-knowledge-representation-system.

If I won the lottery, I'd hire some smart friends to make a new SK8 with an updated version of the old Dylan and a 3D game engine designed for building immersive environments by modifying them as they ran.
The general trend from that data appears that the higher the standard of living, the higher the safety is per driving mile and the US is where one would expect in such a list, better than third world countries, worse than Europe.
This is a lot of good advice, much of which also should be applied in a shared office as well.

I have been remote working for 7 of the last 10 years. Here's my list (in addition to what the author mentioned). Many of the PROs have two sides...

We will start with the assumption that you are ethical and honest (and ultimately, as productive as you should be).

PRO-remote

1. When something non-work needs to happen, it's so much easier to make it happen. Maybe it's the one day of the week when the rain stops, and you can go enjoy sunshine at a cafe. Or maybe the morning powder report says 12" of fresh powder! BAM!

2. So, so much time saved not commuting. And if an office commute is particularly dreadful (gridlock traffic, hot crowded subway, whatever), your quality of life improves a ton by avoiding it.

3. Pets, especially dogs, don't have to be sad and go crazy (literally) at home for 9 hours while you're gone.

4. If your partner also works from home, you have more opportunities for moments of time together (for whatever you fancy). That's valuable.

5. You can work from almost anywhere with quality internet. This can be a huge benefit!

CON

1. Your work is _always_ there. You can end up judging your non-work time against whether it was worth it, or if you should have been working (more) to get more done. This is a huge problem for me, and I frankly haven't solved it. I work 25-50% more than I should now.

2. If your partner also works from home... 24x7 with someone can eventually be a problem. A large home with lots of rooms helps, but going out solo with laptop is sometimes necessary.

3. Pets (or partner!) :). You can feel guilty for not giving attention when someone needs it - because you're busy working as you probably should be.

4. Working from anywhere (especially someplace exotic) - isn't much fun if you're actually really busy working. Then you feel you're missing out. Further, it can make you re-think what's important in life (and make you want to quit everything and live a nomad life - which maybe isn't a CON?)

For me, I'll take remote. Everything considered, my quality of life is much better working remotely.
More relevantly, this is about founders who voluntarily step down thinking it's a recommended best practice to let an experienced CEO take the job once the company is big. That might have been common wisdom in 2010, but it doesn't seem to be quite as common wisdom today, and in any case, that's a very different scenario from a founder who's been forced out or even one who's almost been forced out. The reason to look for a non-founder CEO in this case is some specific belief that this particular person has become bad for the company, not a generic belief that all founders are bad as CEOs.

If drivers pedal errors lead to unintended acceleration in one car, but somehow don't cause unintended accelerations in all the other cars, then maybe there is something wring with how pedal reacts.
Totally depends on where you want to land on the engineering-AI-products to pure-AI-research spectrum.

So, what do you mean by "pursuing"?

But even still, I would caution against trying to upload a bunch of new math concepts into your brain without first understanding the ML/AI context.

I would say go through both of Andrew Ng's ML and DL courses on Coursera.

Then, pick a domain/ problem that you're interested in.

Then, read papers about how ML/AI is applied in that domain.

Then, try to reproduce a paper that you understand and are interested in.

>'It "just works"... except when reviews and ratings and inventory ("just 1 room left!") are bogus, as I experienced last week.'

These are all the reasons to just avoid booking.com. The whole site is like a shady used car salesman - for example returning search results that say -"You just missed it", then why tell me about it? Or "5 people looking at this right now", seriously who cares? Do people really liked to feel pressured? Or how booking.com returns properties with the red "sold out!" in search queries for hotel rooms? Booking.com is one of the most miserable user experiences on the internet and the UI? What a total 1990s looking shit show that is. And of course the reviews seem dubious as you mentioned.

Not OP, but the first 3 months of my current job were remote. It was mostly on our backend and frontend teams to realize that meaning/nuance might be lost in an email or slack message and to hop over on google hangouts (what we personally used, but replace that with phone, skype, &c.). Maybe if there's immaculate documentation and tests, then fully asynchronous communications can be achieved, but, from my experience, there's hiccups where synchronous communications need to be taken to overcome something that's blocking.

Unfortunately many of us in the United States live in huge urban sprawls that are completely reliant on external resources being brought in to sustain ourselves. If the shit really hits the fan, there are not enough resources to go around. No amount of "coming together" can fix that. Stashing away a bit of water and food is not a hard thing. But we all know that most people will not. It is not a question of economic status, but of ignorance, laziness, and whatnot. The decision of ensuring the survival of my children versus helping unprepared strangers in a dire situation is not a hard one to make. I don't think that it will ever come to that but I make no assumptions and so I must prepare anyway.
