Oh, how I don't miss being responsible for building out the holiday oncall schedule.

A few more tips:

- Lead by example. If you're responsible for building the schedule, do a shift yourself, and don't cherry pick the least bad one either.

- Remember last year's schedule: it's shitty enough to do one Christmas, it's worse to do two in a row.

- But also avoid the trap of scheduling only noobs on the worst shifts. At least the secondary should be a grizzled veteran.

- Have an escalation plan in place if shit really hits the fan. Remember the Lizard Squad attacks during Christmas 2014? Good times: https://en.wikipedia.org/wiki/Lizard_Squad

It has two sliders with positions as labeled above, then a rotating knob with 5 detented positions for the fan, and the label PUSH FOR A/C. The COOL to WARM slider is also color coded blue fading to red.

Turning on the headlights lights the display.

No manual is needed to fully operate it. I never even had the manual for that car. The knob and sliders are trivial, tactile, and visual. There are no modes.

It's near perfection in user interface design.
The alt-right needs to go somewhere to leave the rest of us alone. No matter what they will blame liberals for the loss of Voat and other sites. When you have no censorship it is like the Wild West and the biggest guns rule.

Back when I worked as a CO-SYSOP for a College run BBS I had to delete posts that had cuss words in them or were hateful or porno. They had to keep the subboards clean because we had 13 year olds on there downloading info about the college and playing Tradewars, Stock Market, Food Fite, etc. One of the people I censored was Larry Kite, an alt-right troll. Who got mad and claimed he was going to the computer lab to meet the SYSOP and see his boyish face. My supervisor had a beard and met Mr. Kite and explained to him it was not personal we do that to everyone. Especially on networked subs where they have rules against it.

> However, after the universe finishes expanding, wouldn't it start contracting again?

Unless the answer has changed in the last several years, no, the consensus is that it's expanding too fast and has too little mass (and thus gravity) to collapse again.

(Disclaimer: not even an amateur at this, at least not for 40 years.)
Forgive my ignorance here. What do we mean when we say the universe is expanding, expanding into what. My untrained brain is trying to look at it like the inflation of a balloon that takes up more space when it is inflated, but if the universe is all the space there is, what would it even mean for it to expand. Is there space outside our universe that is like unfilled or something?

I remember porting my text editor to UNICOS (someone loaned me an account on a Y-MP I think): it really only had 64-bit word pointers. The byte offset in such pointers were stuffed in to the upper unused three bits. This meant that address arithmetic had better be done with pointers, and not casted to integers.

Also I'm pretty sure ints were 64-bits.. it's possible that shorts were also 64-bits, but I don't remember.
The evidence that dark matter is particulate in nature that obeys the gravitational force, but not the strong nuclear force or electromagnetic force does have actual direct evidence for it.

The other poster has alluded to the bullet cluster. The bullet cluster is a pair of colliding galaxies. We can measure the distribution of gravitational lensing in a region of space, and in doing so, indirectly measure the mass distribution. We can directly measure the light output of colliding gas clouds in the two galaxies. We can measure the distribution of stars within them.

Analysis of this data shows us that dark matter has momentum.

This tells us that if you want to reformulate dark matter in terms of a modification of variations of F = Gm1m2 / r^2 you'll need to do some really ... interesting things. On the other hand, we know neutrinos have mass, do not interact via the strong nuclear force, and do not interact via the electromagnetic force. We either have to assume really, really ugly math in order to give a fundamental force a momentum, or we can assume there are new particles that are sorta like neutrinos but different.

There are other problems that I don't fully understand. Apparently MOND is very, very difficult to reconcile with the rest of known theory if the speed of gravitational waves travel at the speed of light. Which the 2017 neutron star merger taught us that they do.

Another key feature of these architectures is they had a vector length register. This allowed you to write strip mined loops that would move through arbitrary size vectors in units of the hardware vector lane width, without knowing that width until runtime. This means unlike MMX/SSE, the same binary works on machines with different numbers of lanes.

This idea has been resurrected recently with RISC-V and ARM's scalable vector instructions. There the general idea is an instruction that assigns the minimum of an argument value and the hardware vector register length to a register, and sets the masking appropriately if the argument is smaller. This makes for a very straightforward strip mined loop without a branch to check for and handle the remainder in the last iteration.

I've built up all but one of my bikes from parts, but have never attempted to build a frame. I look for 80s steel frames in decent condition and the right size.

My impression is that frame building is a highly intensive hobby and a labor of love. The frames become practically heirlooms. Some of the bikes are just stunning. There's a fair amount of specialized equipment involved, and brazing / welding are arts unto themselves.

Perhaps (just my guess) a bamboo bike is less intensive since it's basically glued together, to over-simplify. This might make it a much more accessible project.
>The idea that there exists some "stuff" we can't measure (except weakly via observed gravitational effects) that is ~5-6 times the stuff we can measure and interact with seems a bit problematic.

This seems to be a common intuition, but is it founded at all? Why should the idea that there's more mass that's weakly-interacting than we're used to be a point against it? Should we have any expectations about the amount of mass that's interactable with us in regular ways we've evolved to deal with?

If we evolved in dark caves to be blind creatures with sensitive hearing and no concept of light, then when we first considered the possibility of outer space, would we be right to write it off just because it supposes that most matter couldn't possibly be heard by us?

If we imagined that all particles we know about may be made up of some smaller building block particles connected together, or concentrations of some kind of stuff, wouldn't it actually be more surprising if all of that building-block stuff had ended up becoming concentrated into normal particles? This might not be literally how it works, but it's interesting that it seems easy to imagine plenty of possible ways the world could be where it turns out that most building-block stuff is never pushed to combine into normal mass, and instead most of it stays in an uncombined form that's only weakly-interacting.

It's about as hacky an afterthought as you can possibly get, though? It's a giant tablet on a stand. Effective, yes, but also definitely a hacky afterthought, too. There's no attempt of any kind to integrate it into the lines or flow of the rest of the vehicle. And they still can't be bothered to put some basic physical switchgear in the thing. There's nothing tactile about it, nothing that feels premium or well-designed.

After using Intellij for about 5 years I switched to a less batteries-included code editor (currently doom emacs). I figure if I need an IDE to navigate our code as a senior developer on the project then less experienced ones don't stand much of a chance.

Thanks. It's hard to express how literally almost everyone who enters a PhD program is coming right out of undergrad and is still in many ways a child. There are no good decisions because making good decisions depends on having good insight and information and guidance, and the only people who can give good insight to the next set of children are either in therapy or quit, but the only people who get asked for guidance are the small fraction who made it.

And the entire system depends on funneling more children into the meat grinder so they have the most perverse incentive to just keep lying about everything. Graduate students are used and abused for a huge amount of lecturing, guiding, and grading so that schools don't have to pay for professors, so that they can have more millionaire administrators and football coaches and replace the flowers in the quad every week and other weirdly expensive stupid shit instead of providing basic healthcare or a decent wage for their lecturers. And then people are surprised to hear that the same schools that have grad students doing a ton of the work for peanuts don't have professor positions available at the end.

I think all people engaging in public speech have a responsibility to be correct, inasmuch as incorrect speech is harmful. The larger the audience, the larger the responsibility.

Let me help you. I offered "Lights" as a design requirement unique to vehicles with respect to phones. Without any explanation it leaves the door open to a surface level counter point "Phones also have lights" that requires a functioning brain and the most basic level of reasoning. Lights on modern vehicles (high beams, low beams, DRLs, blinkers, brake lights) are certainly not simple components, especially those on vehicles sold in the EU where the regulatory body has taken up new technology much faster than in the US. This wasn't a dumb point, cell phone lighting requirements are child's play compared with the requirements of a vehicle lighting. It is 100% valid, but was also placed as bait as explained above. Make sense?

Nazism isn’t just any philosophy that has harmed people though, it’s a philosophy based on the innate premise of harming people. There is a major difference between arguing for something that the other side believe will cause harm, and arguing for something that’s primary goal is to cause harm.

Or, put another way, saying its rapidly getting out of hand because you make assumptions about what else could be banned is the slippery slope fallacy. Saying what exactly constitutes unacceptable speech on a given platform just needs to be specifically defined.

> In my experience most codebases have a pure functional subset, and I believe writing that subset in a pure-functional style is nearly always a win for the long-term health of the project.

I came to the same conclusion ~1 year ago when writing rust.

It's pretty common to have some "high level" method in rust then you split it up, some small parts go into other maybe private methods but a lot goes into split out functions (through this depends on the task, and sometimes could be made into methods if rust would support partial self-borrows).

The only think which sometimes bothers me with that approach is where to place this split out methods. As long as I don't need their functionality in other places I want them to be keep close to the function because of which they exist. But they are function and not methods so placing them in the `impl` block isn't right. Alternatively making them free functions in the method using them seems better but also isn't quite right as this "blows" up the method...

Yes, you're right. Apple silicon does not show up on Apple's list of trademarks: https://www.apple.com/legal/intellectual-property/trademark/...

I'm sure the author should be properly mortified to have used Apple's verbiage to describe Apple's computer without consulting the trademark list.
Ok, name something more complex than a CPU to manufacture on a car?

Making the leap from "Apple makes many complex hardware parts" to they can make a car is a smaller leap than the opposite - Tesla literally didn't exist and made a car, so to assert Apple somehow couldn't is... weird.

Things Apple builds already that are in cars: custom glass, speakers, lights, complex aluminum frames, computers, cameras, knobs/dials, batteries, screens, wheels, fans, materials from leather to rubber to plastic, memory foam...

> It's about time we think outside the box

Another way of looking at it, to add to my previous post: dark matter and MOND are thinking outside the box. They cover both possibilities for how to expand on our current theories: either (a) there's more "stuff" out there than our current theories of particle physics know about; or (b) there's more aspects to gravity than our current theory of gravity knows about. Consider whatever "unknown effects" you like: they will end up coming down to one of those two possibilities.

Thinking "inside the box" would be something like: it's far more likely that either the data is wrong or we haven't calculated the predictions of our current theories correctly than that our current theories, which have tons of experimental confirmation, are wrong. Historically, most of the time in science, when there's been a discrepancy between theories and data, that is how the discrepancy has ended up being resolved: either we've figured out something was wrong with the data, or we've figured out that something was wrong with how we calculated the predictions of our current theories.

The reason why cosmologists are driven to consider models like dark matter and MOND is that they have checked and double checked and triple checked both the data and our predictions from our current theories, and the mismatch hasn't gone away. So they are driven to consider "out of the box" ideas, and, as above, dark matter and MOND cover the possibilities.

You can look at it the other way. Ignore for a moment the surface of the balloon and imagine the insides. As the balloon expands everything inside gets farther from everything else. That’s how I understand the universe expanding.
>and transform "dealer networks" into "maintenance networks".

People tend to overlook just how many service centers are available for the big three (about 10K), not even counting independent garages. Tesla has..500. How many will Apple have? If the Tesla service horror stories are anything to go by, I can only imagine what it would be like for an iCar once production ramps up.
Yes, of course, excuse me. I should have said they are natural high-degree predators. It should also be noted socialization has a direct relationship with heightened predatory behavior in sociopaths: higher socialization translates into better understanding of how to manipulate people. Whereas in non-disordered individuals, socialization fosters empathy and compassion.
Holy fuck. That’s way worse than I expected.

I can’t imagine people actually think like that. They must be doing it for the shock value, or because of some echo chamber effect.

May I ask for a clearer definition of “better off”. From whose perspective? Also does this imply that since going public, google has not been following its mission?

It’s certainly seems true that companies are able to survive on private funding longer than they were a decade or two ago. The longer the company stays private, the larger the IPO leads to bigger payouts for investors and employees that stick around long enough to see the liquidity event and/or have enough cash to exercise their options should they choose to leave. With a strong team, perhaps the lack of public shareholders leads them to pursue more moonshots, shut down fewer products, and find more success but I also think there are downsides.

Chief among them, I think, is that employees generally assume the downside of additional private funding as VCs often get to maintain their pro-rata rights (get to maintain their ownership percentage) while employees get diluted with additional funding. As private valuations rise, option strike prices increase without any guarantee of liquidity in the future. That means employees either need to stick around longer or need to pay significantly higher strike prices for their options without a guarantee they will be worth anything in the future. RSUs (basically options with a $0 strike price) are very employee friendly and many engineers seek them out as they are as good as cash.

As with many things it’s probably a trade off. Perhaps they stay more “true” to the mission without going public, but I would guess many google employees would have missed the wealth brought about by the liquidity from the IPO.

Good question. What do you think?

It will be a mistake to discount either. If anything it’s two likely outcomes are:

- America will maintain leadership in innovation

- Consumers will benefit

Your balloon analogy is almost correct but it's missing one important piece. In that analogy, the surface of the balloon itself is the entire universe. It is a two-dimensional universe. Imagine that there is no other space except for that surface of the balloon. No emptiness inside and no space outside that it's "expanding into".

The entire space is the infinitesimally thin surface which is the balloon surface, yet it is still expanding. Dots on that surface that used to be X distance apart are now > X distance apart in the future. That is all you would know and be able to measure.
