I'm not sure why largeish passive radiators are a problem. If you're worried about the aesthetics you can put them inside of ducts and pass the air over them. This doesn't seem like it should be that big of an issue.

Plus you'll probably want to recover some of that waste heat to heat the cabin.
There's a big difference between "done loading" and "appears to be done loading". Google is reportedly very cautious about the latter, and pulls some hijinks to appear faster than it is. Frankly, I'd be happier if more sites paid a similar level of attention.

That said, if your search page takes over a second, you're right, it might be an issue with your network.

The reason people don't like these replies is not that they're "Reddit style" but rather that they're very low information. How do we know that the "oh wait" picture is actually representative?
Not so much. They blow low frequencies, but not conversation or even music on the subway.
in this case quality just means how likely is a customer to experience issues covered by warranty in the first x days. That's usually called "initial quality" in the industry jargon. Model X was particularly bad off the gates, it had tons of issues especially with the stupid vertical doors that broke all the time.
> To play devils advocate: If he was as brilliant as you imply perhaps he SHOULD have been the one making the key decisions under his purview anyway.

I think you missed the point.

It's easy to operate in a vacuum. If you maneuver yourself into a position where you can only ever operate in a vacuum, you avoid the real difficult work: Coordination, communication, cooperation. That work doesn't just disappear, though. The rest of the team has to pick up the slack, fix the leftover bugs, work around the lone wolf's quirks, and so on.

If a project requires more than a single person to scale, then those people need to work together as peers. If you let one person run away with the fun work and leave everyone else to clean up the bugs and pick up the scraps, it's not a sustainable situation.
What a surprising question. Why?

I always have a wallet, keys (in a coinpurse which sometimes has coins too) and a phone, and very rarely anything else. Sometimes I pack light, sometimes heavy -- enough so that I've been made fun of for both.

I carry a backpack around a lot, full mostly of a laptop, umbrella and jacket. Bogotá rains a lot.
Absolutely agree. This point however is generally only understood by a previously engineer-turned-manager.
It's kind of weird how the US DoD complains about lack of computation power and has to ask the private sector for help, while the NSA [0] apparently has no problem running their own AI program.

Imho way more interesting and relevant than those somewhat far-flung future concepts about fully autonomous warfare.

An industry involved in space will produce the first trillionaire. Simply because the money needed is so high that the return on investment will have to be just as high.
No, the point of the HFT links was to make the most direct shot possible so they could beat the packets traveling via fiber. Going up to space would defeat the purpose.
Go’s GC pauses are on a microsecond scale. If you absolutely need to minimize latency at all costs, I’d be more worried that the Go compiler doesn’t optimize as aggressively as C/C++/Rust.
No, in his introduction it said that this was his hobby. I feel like he would have mentioned if he had any sort of illness, otherwise that would be dishonest writing.
There is a compromise. I have a tendency to work odd hours because it's much easier to get actual work done if there's less distractions. On the other hand, I do feel it's important to have at least 1-2 hours overlap with other people's schedule to ensure that there's buy-in for any major changes in the code base.
RoboTurk: Human Reasoning and Dexterity for Large-Scale Robotic Dataset Creation
The thing I think the spaghetti visual graphs get wrong is a lack of adherence to the structured programming theorem. Most data flows are mostly linear/sequential, and DAGs - which also can be expressed linearly as "send/jump ahead but not backwards", cover most of the rest. Complex structures that need to describe comprehensive fanin/fanout/feedback functionality are exceptions, and as with uses of "goto" in structured languages, most can be reduced to an implementation detail of a single node. So presenting all the options on every node, every time, with cable wiring going everywhere, is a very cluttered syntax for something that could usually be a "Lego brick" expression.

The beauty of stack languages is shared with that of RPN calculators and their postfix syntax model: You can enter the expression very quickly and precisely. Parens and operators don't "get in the way". Names aren't needed for temporary values. Small modifications don't require a rewrite. They feel mostly linear when "in their wheelhouse."

Where postfix starts losing to prefix and infix is when you have something that requires a lot of scanning back and forth to determine state. Function arguments lack clarity. Stack underflow becomes a real failure case. The scaling in terms of readability isn't very good, so "don't write large words" becomes an imperative when it's a generalized programming syntax as in Forth.

The language I'm working on right now currently uses RPN for single-line, compile-time expressions, while runtime evaluation is vertical and operates entirely in terms of keyword prefix + memory addresses, like an assembler. This constrains the scope in two ways, giving it a "twice linear" feel since left-to-right is the compile-time world while top-to-bottom is the runtime world, and those worlds only really cross over in terms of referring to compile-time identifiers(e.g. label and variable declarations, type evaluation). Since left to right is all compile-time, the meaning of an expression can vary a lot depending on the keyword, and so to expand the language I also have the option of adding original single-line DSLs to target specific runtime expressions, if I can't get what I want by adding more types to the RPN system. This is intended for small inline programs called from scripting so the at-scale view of composability isn't the main priority. It's still early, though, so I'll see how that all works out in practice.
> Unfortunately the reduced power is still a problem at higher altitudes but for different reasons. Instead of oxygen starvation, the props will have less to push against.

Yes, but air-density-altitute problems are identical no matter what is spinning the prop, righ?

> This is still less of an issue as the electric motor can spin faster due to the reduced resistance. Higher speeds will create higher resistances from within the motor itself (which will in turn be increase the heat generated in the motor).

OK, so do the math for me here, I am a bit confused. I am not a motor whiz, but torque at the output converted to watts is going to be power at the input less i^2*r losses. The back-EMF will go up as the motor speeds up, so it may be at a somewhat less efficient point on the RPM-versus-torque curve, but the resistance of the actual wires doesn't change.

> That heat will also be harder to dissipate in lower pressures, but I suppose alternative cooling could be added as well.

I think that is all true. Seems to me you design cooling around the cooling capacity of the air flow at max operating altitude. Is that really a huge design constraint?

First amendment apply to the government and anything that functions equivalent to the government. Its that second part that court has made decisions going both way, and the question got mentioned as recently as this year when Trump twitter account got declared to function equivalent as any other official government forum. In that specific case the twitter account of the US president was deemed such, but the whole of twitter was explicitly not judged on.

Beside that, a lot of people talk to media about first amendment they often then go to court raising anti-discrimination laws. Those laws are much more broader and can be applied to private funded companies. When it comes to international companies there is also free speech as defined by the EU and that one do not make a distinction between company and state in the same way as the first amendment. The distinction between free speech (US first amendment), free speech (EU human rights) and free speech (US anti-discrimination) are all fine legal technicallities, but limitation in one does not give private funded social networks free range to do whatever they want.
This sounds a lot like the old Agile slogan for writing software.

The more traffic routes through the satellites vs. the ground the more you'll be competing for that limited sat-to-sat bandwidth and the more queuing delays you will suffer. You want to get the bits off of the birds and onto the ground ASAP if you want to maintain consistent latency figures.

This was a big problem with Iridium. With only one ground station available your latency figures were all over the place thanks to the complicated routing that every packet had to go through.

If you have LinkedIn Premium, you can see they've grown from 188 to 248 employees in the past year. Of those, 8 have been engineers. Overall, it looks like they have about 57 engineers in total now.
Fun little game, and I actually quite like the look of it. For something so minimal, it has a nice feel to it.

A couple of thoughts/ideas:

1. It seems like there's not much of an incentive to have more than 3-4 employees. You can just keep stacking upgrades & self-starter or observation training on one of each, and it seems like it works just as well as spreading them out (hiring another employee gives you a small benefit without upgrades, but not much of one, and has a big downside in needing to click more).

2. The distinction between self-starting and observation is confusing (I know others have said it, but I want to repeat that).

3. Workers completing tasks overrides the description for items in the store, which makes it a pain to read.

4. You can't see how many items are in a given swim lane.

5. Not being able to apply upgrades to an employee while they're working on something is a little inconvenient, especially with the little gap that self-starter has.

6. The emoji for the workers made me think I had unhappy workers and I needed to fix them. That was a little frustrating.

Lastly, a big idea that might or might not be fun: there's no penalty for accumulating a big backlog of work (it's not perfectly optimal, because there's opportunity cost, but you still get the payoff). If projects got stale when they piled up in one column, that could be an interesting dynamic.
I wrote something for myself that removes the editor entirely.

This gives a word sprint of 15 minutes with a visible goal of 1000 words. Hitting ESC leaves it ready to paste elsewhere.

No backspace, no delete, only enough feedback to know your typing is captured, and whether you are on pace.

https://github.com/SteveJSteiner/BantamScribe

It is also entirely local.

Spelling and grammar errors take something like 60 seconds to fix in any reasonable editor that has suggested spelling fixes.

The goal is to focus on the idea and dispense with what should be automated. This is for exploring ideas not refining wording.

For a novel, the choice to edit as you go is orthogonal to avoiding editing during a word sprint. The real issue is during revision you’ll find you corrected a bunch of stuff you are cutting. If that editing was cheap who cares? If you sweated over a sentence for 15 minutes you might do the wrong thing and not cut it even though that is better for the story.
A lot of E46 M3s are still running around with 200k on the clock despite having motors and chassis that chew themselves up. Same with the MK3 Supra and its headgaskets. IMO whether you still see cars around is as much a function of their value retention as it is of their robustness.
For most people in the last 10 or 15 years, search and Wikipedia very often (probably almost always barring casualty treatment) presages what they later go to their doctor about.

What's complicated is Google and others are extreme data hoarders. Google can get the anonymous health records and run a fuzzy match of model records against Home, URL and gmail records. Find high confidence correlations against multiple conditions across the years, where the search preceded new medical entries for those conditions within x time. Now they're in this data set for condition y and oh lookie, they searched condition y related topics multiple times last year. Anonymous record i1389541 is Alice Smith of Wimbledon, set her adwords flags to condition y snake oil, sell record to UK life insurance consortium. [repeat]. No personal data was released, but you're fully de-anonymised.

With enough data and history it becomes absurdly easy to decloak the majority with high or complete confidence.

Welcome to the future.

The alternative is find a way to prevent those uniquely identifying correlations at any point in the future, using techniques we haven't yet thought of. Which is probably impossible without diverging the anonymous medical record some considerable distance from reality. Faked enough to remain anonymous might not be helpful for research into a condition or its diagnosis...
We're not talking about your normal criminals who have some economic motive, we're talking about people who are already acting against their own self interest and to take revenge.

Either way assuming that being armed doesn't provide a 100% effective deterrent, statistics should still help us here. Even assuming a very high deterrence rate, you would still expect to see at least a handful of revenge murders of retired cops every year if this was a significant problem at all.

>provides no defense advantage should they do so

This one should be very easy to determine. How many times each year do armed retired cops thwart revenge attacks?

From what a quick Google search tells me both of these things basically never happen.

Yep particularly in London. Absolutely every new build is advertised as "luxury apartments", but it is all thrown up as quickly as possible to sell either to desperate people trying to get away from renting, or sold off-plan to investors who leave them empty as the price goes up, or to buy to let landlords. A lot of work is done by unskilled labour picked-up in the back of transit vans from street corners on a day by day basis, paid cash in hand.

Landlords especially don't care about quality so long as the yield is good. Who gives a shit if you can hear the neighbors behaving sex or taking a piss if you are not living there, but someone else is paying you £1500-3000 a month for the pleasure? A fancy "luxury" apartment with a flash looking kitchen worktop and fashionable bathroom allows charging a premium.

Any damage or breakage of the low quality construction comes out of the tenants' deposit at the end of the tenancy, and repairs are tax deductible too.

Gas-powered aircraft don't have transmissions, and gas engines tend to only be efficient in a narrow band, so I'd guess that the RPM limitations of an electric motor (which can generally tolerate a wider range) wouldn't be an issue as long as it's a reasonably-engineered motor.

Beyond a certain RPM range electric motors lose torque. Eventually you'd reach the limits of the bearings or the maximum centrifugal force that the rotor can withstand, but that's usually at a higher RPM than gas engines are made to survive. I would expect an electric motor designed for an aircraft would be optimized for maximum power/efficiency at whatever RPM band is optimal for the propeller, and the battery would be optimized for whatever voltage is optimal for the motor at that RPM range.
Hah! I feel like you are writing about me from several years ago, although I don’t believe I was this toxic with my peers.

I suspect they asked mostly mobile users, maybe even a subset of that, because from my experience either this study isn't relevant to my neck of the woods, or people are so taken aback and scared by this person from the wilderness reading a book, that they instantly become fantastic at acting as if they don't care at all.
Can a young child utilize AR on a handheld device? Maybe, although before a certain age 'y' the answer will typically be 'No'. That age y should tend to be more advanced than age 'x' when a typical young child would be able to utilize a picture, say of a cow or a chicken on the same handheld device. Spatial intelligence, IQ, having the full use of one or both hands, etc. are all part of the requirements that determine whether or not any given individual will be able to fully appreciate what's going on with AR on a handheld device. It's entirely possible that adults with different issues will be unable to satisfy these requirements and fully appreciate AR, which should in turn reduce the market for AR on handheld devices.
