> ...most cloud hypervisors, for security/performance/complexity reasons, have stopped emulating the older hardware a lot of "basic osdev projects" rely on.

If you're really determined to do basic/hobbyist OS dev on EC2, you can always just run it under QEMU, which is pretty much what you'd do if you're developing on your own hardware, anyway. I know that's kinda beside the point, and reintroduces all those performance issues, but, security isn't a concern here, and it's certainly no more complex than just running it on your own machine.

There are a lot of people here talking about splitting rent and bills; and the common method seems ridiculous. Messaging out every time you need a bill paid and tracking in a spreadsheet is a recipe for disaster - not getting paid etc.

When I was house sharing (uk) the 'head tenant' would have a second bank account used only for the house. All tenants set a standing order into that account for rent+bills+house items, plus an initial float. After a few months adjust if overspending/underspending. So long as everything is split equally, or those that aren't (ie bigger rooms) are fixed month to month, this is the lowest hassle.

If you want the utility of a pickup truck without the stigma, go for a minivan and a trailer.

Of course a minivan has other associated stigma, but you can haul things around without being asked to haul other things.

I once read an article by a crane operator that mentioned something like 40% of his jobs were for people who saw him craning something and asked if they could hire him to crane something else nearby.
But then you’re driving a minivan.

I love asdf, but one of the reasons it's so great are the other, dedicated, version managers (eg: ruby-build for asdf-ruby, rustup/cargo for asdf-rust etc).

So asdf absolutely needs other version managers. Not sure how a ruby version manager in rust will help - the only thing that's slow with asdf-ruby is building any given version of ruby... And that can't really be significantly improved on? At least not for legacy versions.

I recently bought the complete Don Rosa Library.[1] This is published in the US and it is really well done, with background information on all the works by Don Rosa himself. This is a good sign as it means that Don Rosa's works are not entirely neglected in the US. But of course (and unfortunately) this doesn't compete in popularity with many inferior comics.

In the 90s we lived in SF SOMA and I had a 4WD pickup. It was excellent for hauling antique furniture and oddball arty type things (store couldn't possibly deliver). And it was perfect for exploring the Lost Coast, Trinity Alps, Owens & Saline Valley etc. Manual steering, so || parking was a nice upper body workout. The apartment garage space was $100/month, well worth it.

But... the idea that you would have to plug it in on a multiday trip... yeah, I'm laughing. I just drove central AZ->Sacramento->Ft. Bragg->SF->San Jose->Sacramento->AZ in a Prius. Nope, I'm not digging the charging idea.

I don't recall having that many problems with the borrowers. I helped some people move, maybe once a year. The way it works is they reciprocate with something else, or else, you discover they are not your friend. That's useful to know.
Excellent practice.

I'll also frequently apply this to HN comment streams.

1. Collapse the top comment. It's frequently good, but also frequently is an avalanche of compounded hot takes.

2. Scroll to the bottom of the discussion. Odds are that comments are lower-quality, but not always. I collapse these as I go up, upvoting the underrated ones. Occasionally comment.

3. If there's a long stream of lower-quality / redundant comments, I'll collapse those as well.

I really wish there were some way to surface more deeply-nested, high-quality comments. There isn't. (Though occasionally an email to mods will elevate one to a top-level comment.) There used to be a periodic HN curation. That no longer occurs AFAIU.

Who cares how much energy it uses in aggregate. That energy is paid for. If we are under such an energy shortage problem then I assume individual countries will start rationing it out or switching to renewables or whatever.

It's such a weird attack angle that seems to have latched on some people's minds like glue. Did we ever look at the aggregate impact of every thing in the world? What is the aggregate impact of Facebook? What is the aggregate impact of gas cars? What is the aggregate impact of lawn mowing world wide? What is the aggregate impact of smoking?

Like... of all the things.

It's a global system that runs non-stop, world wide. It would be quite remarkable if it didn't use energy.

> Radiologists have long known that a recent dose of vaccine for shingles, tetanus or flu can cause lymph nodes to appear slightly swollen. But the sudden appearance of so many swollen lymph nodes, in so many women, came as a shock. In many cases, so was the size of the swelling.

The article expresses a measure of surprise because radiologists are. And the degree of lymph node swelling is just one more side effect on the pile (including changes in menses and the rate of anaphylactic reactions) which makes it clear these vaccines are not "just like all those others."
The "negative" impacts of CAFE standards were entirely by design.

> It's a bit presumptuous to suggest the OP "has limited perspective ...

This is going to be very meta and not about salary so feel free to skip :)

When I disagree with someone, I try to find where we are disconnected. It's usually one of two things: we reach divergent conclusions either because we are aware of different facts, or because we're interpreting those facts through different values lens.

A good quick heuristic of a fact missing if when someone talks about either one side of the equation or even worse, makes both sides line up to their conclusion.

For example: "we should use Python - it's the best dev experience, we are only using C++ cuz our lead engineer is stupid" versus "We use C++ because of performance attributes, but I argue we can be fast-enough in Python and get better dev-experience"

The 2nd statement shows awareness of both sides of the argument and then proposes a solution that accounts for them. The 1st side is missing the context for why someone would do something other than what they want to do - suggesting they don't have perspective on that and making it likely that their solution doesn't account for it (or if it does, only by accident.)

In the discussion at hand, the original poster clearly prefers salary ranges and his model for why companies don't publish them is that they are evil. To me that suggests that they are lacking perspectives on the cases where salary ranges are either impossible to share or end up working in the employee's favor. Having had this conversation many times before, I attribute this lack of perspective on not having the senior hiring experience either from candidate or company side where one would have picked up the perspective.

To sum it all up, yet there's a bit of presumption in my suggestion but at the same time - you have to be able to assert things or else you'd never be able to make any points.
>you can't really get small pickups that size anymore

Write your representative and tell them to thank the EPA and NHTSA for doing their jobs. The death of the small pickup is squarely the fault of the confluence of fuel economy and crash safety regulations.
For those in a similar situation, note that most home-improvement stores rent a pickup for something like $20 for 75 minutes, usually enough to get a load home.

And one step up from that, full truckload delivery is often $75-150, and sometimes even comes with a forklift. Often you can get it thrown in free if the order is large enough.
The magic of silicon carbide. Remember, having a 3 phase input means you have 1/3 the current per phase

Though, I will concede on the price estimate. At 250kw, you get 180A per phase, which is still outside of range for commodity parts. And at 350kw, switches which can handle 250A cost few hundred dollars each.

Alternatively, you can use a 3 phase transformer to 1400V, and rectify to 800DC.

Some people seem to enjoy passing moral judgements onto others.

What doesn't make sense to me is when someone who drives any gas car judges someone who drives a truck. Do they feel validated in their choices because someone made worse choices? Or do they decide that 30mpg is such a morally superior position than 20mpg that they have the right to judge others?
> Especially on MacOS, when the scrollbars are hidden.

Do other OS not do that? It's a terrible thing to do by default — I wish we could convince Apple, (etc.?) to fix their mistake rather than having to work around it.
> Those parts are made out of the same materials (rubber+metal+plastic+ceramics+lubricants) as in electric cars.

Most electric motors have none of those materials except metal. Most are induction motors with few to no moving parts internally, and those that do have moving parts don't need them lubricated because they are in naturally low friction arrangements. (Versus pistons that have to be as tightly fitted to chamber walls as possible for the most power in an ICE.) Most EVs you can expect the motors may outlast the plastics in the dashboards.

As for batteries, Lithium is easily recycled today. We don't have a lot of Lithium Ion battery recycling plants today because of economies of scale. There haven't been enough EVs for long enough today to have big needs to recycle their batteries. Most of the oldest EV batteries are still on the road. So far EV battery life has well exceeded expectations, across the board.

You can get a truck, in CA, for less then $10K (including initial repairs). Why does everything need to be new?

The truck I got about 9 months ago has already paid for itself by saving me from having to hire people to do things that I could have done myself if only I had a truck.

Renting is fine once in a while, but if you're hauling base rock or lumber every few weekends, I cannot imaging having to deal with rentals every time. It doesn't make sense, and would be such an enormous waste of time.

Comparing actual stopping distances for passenger cars and light pickups:
https://special-reports.pickuptrucks.com/2015/01/2015-annual...
https://www.consumerreports.org/car-safety/best-and-worst-br...

Basically light duty trucks take an extra 10-30 feet stopping from 60 MPH. This is dwarfed by distance travelled during reaction time. In the 1960's sedans were in the ~150 ft range for 60-0, about what modern pickups achieve.

Heavier vehicles have more kinetic energy at the same speed but the braking force for all vehicles is proportional to mass and friction with the road surface which depends on tire quality and road material, and since acceleration is proportional to mass from a given force the deceleration from braking is basically the same at any mass with equivalent tires and road surface.
There is lollygagging in irrelevancies, and luxuriating in details.

France has a huge tourist economy and weirdly the reason it does it because it's France and full of French things.

The trouble is, the sound system is inevitably connected to the rest of the car. For example, in most cars the volume automatically increases with vehicle speed to compensate for increased road noise.

These connections could be physically 'one-way' but in practice most modules are simply wired in parallel on a CAN bus and something like the radio would be set up to
send data to the car's CAN bus (for diagnostic purposes at least).

Yeah the last line had me scratching my head for a bit. Cool stuff.
There’s a lot of times it’s more convenient to just throw something over the side of the bed so I would miss that but as a purely utilitarian vehicle vs a work truck absolutely yes.

However for my truck in particular I got a somewhat luxury trim with 50k miles for only $20k, so it was a good mix of things I would want in a vehicle generally as well as the utility. Panel vans aren’t really offered in that configuration, and I probably wouldn’t get one now because I plan on just keeping this truck as a secondary vehicle long after it’s paid off and I eventually get a smaller daily driver.

All that being said the one thing that could make me change my mind is an electric van with extensive usage of solar panels. That has a rather unique value proposition so if it existed in the future I’d be interested in it at least.

>Whereas the classroom usage of mathematical/programming notation does not.

i won't speak to programming notation but every upper level or grad math class i've had has been at times extremely informal in its use of notation. take an integral on any chalkboard in any class and you're almost certain to have these questions without listening to the lecture itself (i.e. it's omitted from the notation):

1 what is the domain? R or C or something really exotic

2 is it over a closed contour/boundary or open?

3 what's the metric? i.e. are we actually integrating forms?

4 is it even an integral at all not just shorthand for solving a differential equation (e.g. stochastic integral)
You can, the return statement is essentially a popcount.

c1 = 0x8080808080808080
c2 = 0x7F7F7F7F7F7F7F7F
c3 = 0x0101010101010101

e = ~(x ^ y)

return popcount((e & c1) & ((e & c2) + c3))

For those wondering how this works. If two bytes are identical, then the XOR will yield 0x00 and the negation will yield 0xFF. Masking out the seven least significant bits with 0x80 will just yield 0x80 again. Masking out the most significant bit with 0x7F will just yield 0x7F again and adding 0x01 will yield 0x80. Finally combing 0x80 and 0x80 with AND just yields 0x80, i.e. exactly the most significant bit set.

On the other hand if two bytes are not identical, then at least one of the two following things happens. The two bytes differ in the most significant bit and therefore the most significant bit of the XNOR is zero. Then masking out the seven least significant bits with 0x80 yields 0x00 and therefore the final AND yields 0x00.

Or the two bytes differ in at least one of the seven least significant bits and therefore at least one of the seven least significant bits of the XNOR is zero. Then masking out the most significant bit with 0x7F yields something smaller than 0x7F and adding 0x01 yields something smaller than 0x80, i.e. the most significant bit is zero, and therefore the final AND again yields 0x00 because the first operand is either 0x00 or 0x80.

The remaining work is to count the number of set bit, either with popcount or some other construction like the one in the article.

My first vehicle I bought with my own money was a truck. In retrospect, it was a mistake. It got shitty gas milage, had downright dangerous performance (0-60 in 16 seconds made for some white knuckle backroad passing), and 90% of the time my bed was empty.

If I had been smart, and bought a small hatchback or wagon, I'd probably still be driving it to this day, and it'd have 90% of the hauling capability of my truck.

An electric pickup solves a lot of the issues I had with my old truck, but understand, this is a premium product. Pickup truck owners are a stubborn bunch. EVs will have a hard time penetrating that market. It may take a few decades.
