I keep sending copies of this paper to numerous colleagues. AFAIK almost none of them finished (or even started) reading it. I’m at a loss to explain why, since it is such a deeply insightful paper.
50% range increase would be a huge boon to a vehicle like a Boosted Board. My V2 throws off a lot of heat and gets nowhere near the advertised 11km range.
Probably until we get AGI, since I looked at the threads and decided which ones were interesting. It's often the case that several searches are involved, too; not just matching identical URLs.

I posted the article here - I wasn't aware of the previous discussion on HN. I guess there's probably a decent percentage of other HNers that wasn't aware either.

I also wasn't aware of the dallasfood article either. You raise good points, but I don't know how I could have acted differently...

I think you're being too honest. I wouldn't blink at any of my employees spending an hour a day at continued education, self improvement, etc. 2 hours a day... Might be pushing it a bit. The 1/he a day is for non-directly work related things that might come up later (i.e., learning network programming or systems or databases, whatever), whereas if you are claiming to make yourself better at your current taskset... There's nothing better than actually DOING that.

Anyway, all that to say that if my employees spent only 35hr/wk being productive with the other 5 for learning, I'd consider that a fine allocation.

Edit: actually not even 35hr, I just can't quite bring myself to support a blanket 2hr a day for this specific non-business productive activity. 35hr/wk of productivity is a bit of a pipe dream

> In a world (like ours) with limited bandwidth

That is actually the first mistake in your argument in this context. The bandwidth limits in mobile networks are first and foremost an effect of decisions by the network operators, not an inherent property of the world.

> you sometimes want to limit flows in a way to produce the least harm. Throttling different streams has different effects on user happiness.

Well, maybe. But I would argue that that is both (a) prone to erroneous valuation, if only due to conflicts of interest, and (b) almost always only the case to any significant degree in very artificial scenarios, not in the real world.

> For instance, if you are 100 Mbits over capacity, you could either:

> (a) Throttle 100 users Netflix streams, which drop from 1080p to 720p

> (b) Throttle email, it backs up causing hour-long email delays.

> One is obviously less harmful.

Primarily, that's a nonsensical scenario. For one, you are never "over capacity". That's what capacity means: The maximum speed at which you can transfer data. You never transfer data faster than you can. You are only "over capacity" in the sense that the link is congested, but that isn't a data rate that you are "over the limit", it's just that the queue starts to grow.

But also, your scenario implies that throttling email more than its fair share somehow would cause "hour-long email delays". Now, I dunno, what would that look like? 100 users using netflix, ~ 10 Mb/s each, for a total of 1000 Mb/s, and one user sending emails at 1000 Mb/s, which would then lead to the email sender being throttled to 950 Mb/s under fair sharing, which ... still would not lead to anything remotely like "hour-long email delays", despite being a totally contrived scenario?

It looks more like you just made up one bad thing and one not so bad thing, and then noted that the worse thing is worse. Which is fine. But it is completely irrelevant to the discussion if you do not demonstrate how those two options are actually options in the same situation, and how they, respectively, compare to fair sharing.

Any large country will try to exert influence to keep the world in a state they are happy with. It's an extension of human nature. Considering what the US could have done, their footprint has been relatively mild. Most "interventions" were to keep authoritarianism limited. If you are pro-authoritarianism, you indeed may see such moves as sinister. (I won't put a value judgement on authoritarianism in this post.)
Ask HN: What’s your favorite bad startup idea?
I like coming up with bad startup ideas: they sound like something that could be real or funded but are actually terrible. Here’s some of mine

* NapApp: AirBnB for naps. You don’t do anything with your bed during the day, so why not rent it out to strangers hourly to take naps. NapApp comes with a NapMap for you to find the nearest bed
* Audiogram: a completely audio-based social network. No visual interface. You can only interact with it via your voice and post audio clips (apparently something like this already exists)
* Service-as—a-service (not my idea): church service in an app

Got any that you like?

Ultimately I think these numbers do matter. As chips approach the size of human brains, only 1,000,000,000x faster, you remove the question of engineering and scale, and are left with just research.

The format of the top comments are all similar.
20-30 words staying under the "Read more" limit, “I am X, I support China", 200-250 upvotes. Replies are argumented with links to anti-US articles.

Not very subtle, this was probably just homework for the interns.
I had a short browse and I was really impressed by how much nicer to read you have managed to make wikipedia. Normally I much prefer static HTML to whatever mess the latest javascript framework manages to conjure up but what you've done really seems to work.

The text actually fills the screen rather than just hiding in the gutter on the left, and even though you've removed most styling cues around links and actions, it's done in a way that it's still obvious what everything does, so the main content can be clearer.

The dynamic sidebar table of contents is also particularly effective - on desktop, everybody has a widescreen monitor now and it's disappointing now few sites take advantage of it.

My only two critical points are your choice of typeface, which is awful and significantly degrades the experience (browsing with fonts turned off is a great improvement), and the speed - not only does clicking a link take several seconds to do something but there isn't really any indication whether things are happening or not.
Nice! I like this idea and look forward to seeing it develop further.

A bug to report: inspired by comments elsewhere in this thread, I searched for "radiation", and your interface is rendering the bulleted list about different kinds of radiation above the actual first paragraph (which ends with "This includes:" to introduce the list).
China will not be able to shoot down satellites just to stop video feeds escaping. Its an act of war. Also the USA will surely have capabilities to resist such attacks, and it only takes 1 stream to get through.

Democracy/free-enterprise need only hold its nerve, and it will win. Not for some moral reason, but simply because the overhead of maintaining a police-state is so much greater than a transparent society.

Can you provide an example? I have a hard time believing any arbitrary computation can be build without conditionals.
I personally think you had a strong answer despite the criticisms mentioned.

But, yeah. Casing convention was surprisingly important in one of my interviews. They wanted to know that I was able to adapt to a new language as the job was for a language I didn't have on my resume. It's weird, but I understand where they're coming from. Seeing improper styling in a code review is an immediate red flag and an interview problem is ultimately a code review.
And how is this indicated to the user? At least the ride hailing apps displayed their "surge pricing" before you used the service.

Good point. I found this - https://www.pcgamer.com/the-future-of-kerbal-space-program-u... which provided a little more context, but I'm at work and can't really dig into the background or current state of Squad.

My hope is that whatever team builds KSP2 does it with some level passion and care, like the first few years of KSP1 had, and perhaps without repeating the same mistakes KSP1 suffered from.

Surely there need to be weightings? If any amount of profit is better than any amount of other benefits, how is the situation different to now?
Ah got it, thanks for the concise explanation.
A lot of performance-sensitive code involved in game development usually eschews garbage collection, as pause times can affect per-frame performance budgets non-deterministically.

It's partially why Rust and modern C++ are getting a lot of attention in that space, as they provide a lot of higher-level niceties but don't require the overhead of a GC.

> My V2 throws off a lot of heat and gets nowhere near the advertised 11km range.

Heat losses come in many forms:

- resistive losses in wiring

- resistive losses in the batteries themselves

(their Ri is nowhere near zero)

- switching losses in the powertrain

- slip losses between the field and the rotor

If a piece of gear does not get its 'advertised performance' that can mean a defective product, deceptive advertising or plainly bad design, or a combination of all of these.

Having a very expensive motor isn't suddenly going to solve any of that, you'll get an advertised range of 15 km while being able to do only 10 and you'll still feel cheated.
I know you didn't explicitly say "you only use Apple products because you've been suckered in by advertising," but it's hard not to take it as the subtext, and it's something that's long rubbed me the wrong way.

No - what I mean is that if someone is worried that their code will be derived from their published hash by someone doing a brute-force attack, they can prevent (or make much harder) this brute-force attack by having comments in their source code.

I'm assuming here that the hashed string is the source code rather than the machine code.
You can index rows in DataFrames in the same way you index rows in matrices:

julia> df = DataFrame(x = 1:10, y=2:11)

julia> df[1,:]
DataFrameRow
│ Row │ x │ y │
│ │ Int64 │ Int64 │
├─────┼───────┼───────┤
│ 1 │ 1 │ 2 │

julia> m = rand(10, 2);

julia> m[3,:]
2-element Array{Float64,1}:
0.013457628869001814
0.2632480919750453

As for static typing/static analysis, that's something that can be built inside Julia (and several projects have done so). Personally, I would not want Julia to insist on static typing and much power comes from not overspecifying types.
Historically the most effective propaganda has been based partially on fact. Outright fabrication doesn't work as well as taking an accepted fact and twisting what came before or what will come after.

Coal is cheap... at the moment... and

China has a backup store of coal it bought from Australia and stockpiled for decades.

China can command what ever price it likes for its coal if other countries refuse to supply coal to run these new power stations.

China can supply coal for long enough to get them into debt and sell out to China.

So it makes complete sense for china to go off coal.

In what kind of society do you live where some swearing could even be considered not "safe" for work. People swear all the time.

No mentally healthy adult is going to drop into fetal position and commence a nervous breakdown because Tim snubbed their toe and went "fuck fucking shit".

As long as the swearing isn't directed at coworkers or some racial slur, who cares. If anything it might lighten the mood.

The kind of theoretical place your post is alluding to sounds stuck up and devoid of humanity to me. And also probably doesn't exist. Hopefully. I wouldn't put it past some US companies.

SFW was originally used to tag content you yourself can watch at work without experiencing the awkwardness of having a bunch of penises/breasts/whatever on your screen. It was never meant for creating safe spaces for victims of pathological parenting.

I can only assume that this is what reddit means here. It would be similar to Twitch in that regard (i.e. no nudity).

tl;dr: Nobody will ever care that you're reading/watching the recital of a poem consisting entirely of swear words while giggling manically over your lunch.
I find it awesome that you can do that, the extra flexibility is great, e.g. when you're working with const char* arrays, sometimes, you need to create a copy of that char array, but save its pointer (char* ) in a (const char* ) variable, but you're still going to need to delete that copy later... and then you're glad that you can simply recast a (const char* ) into (char* ).

I save the data of whether or not it's a copy into a flag variable, so my program knows when and when not to delete a const char* .

The alternative would be of course to create a two variables, one char* and one const char* , but that would double the memory needed, but only one type of variable would be used at a time.
I don't see an issue with throttling video at all - the idea that I can bang a 4K stream down on LTE, which might be limited to 100mbit from the tower for everyone, means that's necessarily going to happen.

That said, I use secure encryption to prevent the ISP from viewing my browsing habits. Throttling VPN use carte-blanche because you don't know what's in there would be overkill.

It seems to me that it's best to just throttle based on allowing burst usage and treating all bulk downloading including streaming video identically.

Returning to the math, I did the calculations and here is the margin of error for each group: 11%, 9%, 9%. Their common error (the overlapping region of area) is the interval 87.79-104.95. The IQ scores from each group (94.91, 96.29, 96.47) are well within that margin of error. If you perform a t-test on 3-Ca vs. 3-placibo you'll see that the difference is not statistically significant.
The key is memory. In the moment, it isn't necessarily obvious that the Chinese Communist Party is misleading us any more than their opponents are. However, we have observed the Chinese Communist Party for decades, so we know that it is highly likely for them to lie, murder, intimidate, etc. That helps us evaluate what we're seeing at any particular time.

Eventually this sort of media analysis becomes a sort of clairvoyance. Intelligent news consumers responded to June's "Gulf of Oman" incident with questions about the "Gulf of Tonkin". Earlier, we had also questioned the official narrative about gas attacks in Syria. Now it's clear that was all bullshit too.

You have to prioritize something. Development of other features was prioritized over async first. Futures support came later, and async later still. It's an iterative approach. In the end, it let people get a LOT of value out of rust well before async was fully baked.

For myself, I'd been waiting for the syntax to finalize as I'm still learning and didn't want to really delve into old and new ways, though I'm sure I will see them in practice. For others, depending on your needs, if you didn't need it, or willing to jump through the hoops, you could still get value along the way.
> It didn’t have to be like that, honestly. Imagine what might have happened if, for example, Microsoft worked more closely with the Wikimedia Foundation on the highly visual treatments the company was known for with Encarta. The nonprofit ownership was a good move, but the fact that MS seemed to cede the market entirely, especially so soon after disrupting the whole thing, was unfortunate.

We actually asked them about this, IIRC - it turns out a lot of that stuff was licensed from third parties, and they weren't free to release it under a free content license, and didn't have the resources to sort out what was what.
Why did so many Neanderthals end up with swimmer’s ear?
Many laws exist that express the intent of a law-making body but are either unenforceable or too expensive to enforce in any meaningful way. Perhaps the const declaration in C is an example of this type of law.

In contrast, a Standard ML compiler can enforce this law because the language itself insists that all bindings are immutable.
