Generating “happy accidents” are my primary interest when it comes to using ML/AI for music composition. 8 times out of 10 I can generate my own but I’d love to be able to cover that last 20%. This seems like a sweet spot for current technology.

Any chance you’ll open source your approach?
this is probably a major part of why he's leaving, so his presence can't be used as ammo by detractors. it always seemed like a major weak point for the project to me; you can tell they've been trying very hard to avoid any related subject in interviews etc
"The team was able to discern that between 1979 and 1990, Antarctica shed an average of 40 gigatons of ice mass annually. (A gigaton is 1 billion tons.) From 2009 to 2017, about 252 gigatons per year were lost."

I'm a climate skeptic. This type of research is why I'm a climate skeptic. 252 gigatons per year means a bit less than 0.001% of the mass of the ice sheet of the Antarctic continent. Or, to put it differently, about 1.8cm decrease in average ice height, when the current average is about 1.9km. They are telling me they have a method to estimate an average decrease of 1.8cm? Really? How can anyone claim such a thing with a straight face? Civilian GPS doesn't have this type of vertical resolution. You can achieve better resolution by the law of large numbers, however that is at the rate of the square root of the number of observations, and I doubt there are a tremendous number of observation points in Antarctica.
Hotel California seems like the coolest modern version of that chord sequence, in a minor key no less.

Actually, you do have the right to fly over someone else's property. It's well established law that Delta airlines does not need to ask permission from every land owner that they overfly.

A long time ago, property rights were 'Cuius est solum, eius est usque ad coelum et ad inferos' -- from hell below to heaven above. (now referred to as the 'ad coelum doctrine') But that law was changed a long time ago. Just because you own the land, doesn't mean you own all of the airspace above it.

It has been tested in court that a property owner owns some height above the surface of their land. 300ft over the tallest structure is definitely in the public domain. However, the minimum altitude that one is allowed to fly over private land without permission has not been established in court.

A drone at 10ft could definitely be pursued for trespassing. A drone at 400ft definitely could not be pursued for trespassing. A drone at 150ft? That still needs to be tested in court. Then general rule is that a property owner is entitled to the enjoyment of their property.
Hold on they were not allowed to do secondary offerings? Or debt raise? Have you seen the stock price of PCG? Share price trend does not resemble a company with financial troubles.
I'm a little jealous. The whole exploration/discovery angle sounds like great fun.
>First thing they should do is to cover propellers so that they don't hurt anyone.

Does anyone know why this isn't standard?

I Googled this question: "why don't quadcopters have safety cages" https://www.google.com/search?q=why+don't+quadcopters+have+s... ...

... and even saw cages that go around the whole quadcopter (not just the propellers as I was expecting). If those were a bit squishy they could seriously reduce any chance of concussion/property damage if landing on someone or something!

The YouTube video below is pretty amazing, it shows someone demonstrating such a cage.

"Spherical Cage Incased Quadcopter" - https://www.youtube.com/watch?v=5B3X6EvZ2XM

I've submitted it as a separate submission. (It's only 2 minutes.) He says it flies great, and he even seems to purposefully drop it several times from as high as the height of a building.

Also for anyone who hasn't been around drones much, in the middle of the video you can hear the annoying whirring noise people mention throughout this thread.
FDB does not automatically index your data, but you can write a layer (like this one) to index your data.

In a transaction, you write a key like “users/1” with a value of “bob” and then write another key like “users/bob/1” with no value. Then you can do a range scan over the prefix “users/bob/“ and find all the primary keys. After that you do individual gets for the keys in the PK index to retrieve the full record if needed.

The comparison between the two is FDB “secondary indexes” are just like anything else in FDB. Namely, you update them in transactions and they are consistent immediately. Scylla does not AFAIK have this feature.
I work on a >100KLOC Flow codebase and I can tell you the type checker is anything but instant.
The recent scandals about DDR4 price fixing lead me to believe it's probably collusion.
I'm just pissed that WiMax didn't get a fair shake thanks to Qualcomm's shenanigans.
It's a tedious fruitless argument that goes back years. Some people in the "Common Lisp camp" believe that Common Lisp has the "rights" to the 'Lisp' "trademark."
That is because few people really care and aware of it.
Consider using your time off to take up a trade. Personally, I’ve found working with my hands outside of tech cathartic (welding specifically), and will eventually transition out to either a trade or law after tech (where there is no treadmill, and taking a year or two off doesn’t sideline you permanently).

Tech is like being a sports athlete or exotic dancer; make hay while the sun is shining but always be prepared for your next act.
Solid is open source and you do have control over its code.
Glad to hear Typescript is winning hearts and minds. They’ve been great maintainers; avoiding the infighting, toxicity, and the perverse incentives that unfortunately plague the front-end landscape.
Care to share a couple pics?
Regarding Typescript specifically, I'm a bit torn.

I used to be excited about it but after a while of using it I see it more like a tool to migrate existing JS code or to interface with existing libraries written in JS, and not like an ideal tool to write code from scratch.

The reason is, the type system is actually incredibly complicated (to accommodate to all sorts of silly and messy things you can actually do in JavaScript).

I'd prefer using a more principled language for brand new projects. Which language is that? I'm not sure yet, but dynamic vs typed doesn't seem as important to me. I think ClojureScript is a better language than TS. Kotlin/JS also looks good, for a less "alien" language that is still better typed than JS/TS. But I don't have experience working on medium/big projects with these yet.

OTOH, for browser apps, the main plus for TypeScript is that if you pick a subset, ala C++, you get an OK language that never gets too far away from what you actually get when you convert the app to JS, so easier to debug and sometimes reason about.

So there you have it... I'm torn :-)
>They're going to be constantly landing and taking off to deliver the package, right near you.

For delivery, would using a (possibly guided) parachute be an option sometimes? For example if there is a landing target left in someone's yard.
Most of these ice mass measurements are made using GRACE not physical height / GPS measurements. Ice mass loss appears to be accelerating by multiple forms of measurement.

Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back.
All due respect I don't think the article proved or indicated that "everyone has an ideology which overrides logic on many topics."

The study found that people are less successful at spotting logical fallacies when the conclusions are supported by their politics.

This is itself an interesting finding, but (1) I don't think the "everyone has biases" argument is justified by this article and (2) that precise argument is often used by people to apologize for allying themselves with others who have abhorrent views but are otherwise inline with their political interests (e.g. White Evangelicals in Iowa who vote for Steve King). I'm 1000% not suggesting that you're doing this but I think it's an unfortunate conclusion many draw from your argument.

Yes everyone has some level of irrationality but not everyone has a sound ideology, many people often waiver between conclusions and human judgement is real, important, and helpful.
I was mostly talking about the concept of mitochondrial incompatibility, which is significantly more common than what is discussed in the paper, which is paternal inheritance. I made a note of it being doubly rare (female must survive to reproduce age with a specific mitochondrial sort of defect)
s for silent? I mean, all the text on the page is flashing on and off in sync..the whole page goes black. Its the first ESC code in the downloaded text, I guess..haven't quite figured out how to block that yet. If I then do an 'ls' (100s of files in that dir) it stops flashing, but when I scroll up, the first ls-ed files stay flashing..
> would have been nice if the author also had analyzed chord progressions instead of single chords

Last heading in this first section:

“If a song happens to use a particular chord, what chord is most likely to come next?”
> Does anyone know why this isn't standard?

Because cages weigh more. Minimizing weight is critical for anything that flies. If it weighs more, then it takes more energy to make it fly. If it weighs more, then that's less payload that it can carry.
On the other hand the human life & culture we've developed might not give us a "realistic" means for dealing with the environment and climate change. Reread what you've written and look at it from the perspective of someone concerned about climate change, whose read the reports that we're likely to see effects of it within our lifetimes, and who lives in a world where the response to a progressively worsening disaster is ranges from "not my problem", "don't be so negative", to "what can we do?".

Young people today are born into a world with a considerable amount of inertia leading it to a not so happy place. The evidence points to this not being just pessimism, but a reality they will have to face and deal with in their lifetimes. Rising sea levels, political instability as once habitable and arable land become inhabitable and barren, increasingly sever weather, etc. Pessimism and optimism in this case refers to how severe these problems will be and whether we can either put them off or mitigate the consequences, not whether or not they are happening.
A great deal of comments here want self-hosted capability, understandably given the HN crowd. But really, Notion is (probably) not in a position to do that, given their code being proprietary from Day 1.

I run PageDash [1], a personal web archive service, and that is also the No. 1 ask. While I can understand it, for any startup to focus on self-hosting from Day 1 is probably a shot in the foot, unless I have an open-source model from Day 1.

Just a cautionary note.

I'm guessing it was the both sides thing, which assumes a binary opposition as a starting premise when many issues are multidimensional.

The downvotes on your own comment may be because one of the HN guidelines discourages commenting about voting patterns.
Sure, SmartZap electricity may be cheap and the app is super intuitive, but they’re subsidizing rates through VC funding and not paying their “independent contractor” installers a living wage.
Any pointers to an opinionated install guide that does not require me to configure every aspect of the system? Something that yields a working gnome/kde desktop with less than 10 minutes of effort would be ideal.

I think Jose and team have done a great job with this, especially judiciously limiting what features get added to the core language.

This is also an area where Elixir is benefiting greatly from the maturity and ongoing development of the Erlang VM. Elixir is, in a sense, simply a text based interface on top of the BEAM.
Just bought MX500 2TB in black friday for about 200 euros. Maybe it will getting cheaper this year, but 0.1 EUR/GB is already a good deal for me
As someone not from the US how could you be compelled to unlock your device using biometrics? Does this actually involve violence?
Also notable for a huge increase in TDP from the next-slower model (255 W vs 165 W) - and it has four fewer cores.

> Other details about the chip that we have learned include that it will have a listed TDP of 255W, which means the peak power will be higher. Motherboard vendors will have to support 420 amps on the power delivery for the chip (which at 1.3 volts would be 546 watts), and up to 30 amps per core.
Yes! My biggest single complaint about drones is the noise. I also own and fly a drone (for professional photography and video work) but I am LOATHE to fly that thing when anyone else is around. It’s just so dang annoying.

As a drone owner, it drives me bananas when I see people just flying them all over the place with no account for how irritating the noise is.

If drones could be made substantially quieter, everyone’s quality of life would go up and we could be saved from inconsiderate people with no regard for others.

do you really believe that someone who writes so terribly is also writing with "erudition, scholarship and analytical ability"?

I recently reread his "Open Letter to Open-Minded Progressives"[1]. When it came out in 2008, I thought it was brilliant. Rereading it now, I find it both brilliant and prescient. Here for example he casually predicts the strategy used by our current president:

Fourth, there is another way to succeed in the Outer Party. This might be called the Huckabee Plan. On the Huckabee Plan, you succeed by being as stupid as possible. Not only does this attract a surprising number of voters, who may be just as stupid or even stupider—the Outer Party’s base is not exactly the cream of the crop—it also attracts the attention of the Cathedral, whose favorite sport is to promote the worst plausible Outer Party candidates. As usual with the Cathedral, this is a consequence of casual snobbery rather than malignant conspiracy, but it is effective nonetheless. It is always fun to write a human-interest story about a really wacky peasant, especially one who happens to be running for President.

Yes, his writing is verbose and pretentious. No, you probably shouldn't trust any of the conclusions he reaches. If you have any sense, you should publicly disclaim any familiarity with him or his works. But with all seriousness, I (having no such sense) would claim that he has written the most incisive political analysis published yet this century. Ignore him at your peril.

yes but drones can get away much faster making it completely worthwhile.

drones can also record entry passcodes, snap pictures of keys and license plates, spoof gps, carry guns, spray toxic gas, drill through buildings and sniff EM fields to see who is where and when. perfect legal data to resell to unsavories.

this would be a security nightmare.
INAL but I believe its usually contempt of court, you'll be locked up til you comply.
I see method of loci more as "ram", whereas spaced repetition is moving things into a hard drive. For example, when reading, I'll often use a mental room with 10 spots x 3 key points per spot to keep an outline.

Periodically, I'll go back and walk through the outline, looking up details where I have gaps (ie spaced testing). It's helpful that a spatial path lets you easily keep the temporal structure of the narrative.
Genuinely, I think you're missing cultural context.

Many of us share a general lighthearted humor about the state of the industry: Becoming a developer in some fields is less about engineering and more about "piecing things together."

Nobody's looking down on anyone. This is often something we joke about because we find ourselves piecing things together, too, almost to a point of silliness. It's not a rip at anyone sharing information, more like a jarring reality check.
While I believe in free expression, I also believe the internet should show a human-like characteristic to forget i.e. old items, news, etc., non-scientific news and such should slowly decay in relevance and drift downward in indexing, so that that idiotic tweet and that drunken spouting off by Jill ten years ago doesn’t haunt her as if she did it just yesterday.

People make mistakes, we are fallible. Unless it’s a felony, these things should not haunt people who have learned and matured enough to have not made the mistakes recently (and thus recorded/indexed and available)
Actually court orders do that all the time. Sure, it can't stop physical force being used but it can invalidate the results for legal purposes.
Precondition (called invariant here): a set of conditions that must be met in order to call a method. Another name for argument validation, but it can be other things (e.g. connected must be true before calling methods on a connection).

Postcondition: guarantees that a method makes. For instance, it won't return null.

Invariants (incorrectly used): conditions that always hold true on a type, e.g. the starting index on a slice must always be greater or equal to zero.

https://en.m.wikipedia.org/wiki/Design_by_contract

I guess D is guessing via implications, but from what you've said it can't support invariants, meaning it doesn't strictly qualify as DbC.
The medium account of the article you linked to was suspended, the article cannot be accessed.
Ehhh.

Take for simplicity a constant real number. A constant is not a function but there's a function from the reals to a space of real valued functions. Likewise every vector can be converted into a cove tot, but...

You can say these function-valued functions are bijective so you can work on either side of the fence. Your can also work with equivalence classes if you don't quite have a bijection. But a lot of mathematics is about being specific about what we want, even if we're lazy in writing later and smush related concepts together in the same symbol.
I'm pretty happy with Gollum (https://github.com/gollum/gollum/wiki) for this. Your data is just a Git repository containing a hierarchy of files. You run Gollum to fire up a local web server, which gives you a wiki interface to view and edit any Markdown files in the hierarchy. You can use a local Markdown editor if you prefer, as long as you commit your changes. You can choose whether to run Gollum all the time and expose the server to others, or just launch it locally when you want to browse your own repository. And you can use Git to create, push and pull branches.

Gollum also seems to have powerful customisation features like macros and YAML front matter, but I have yet to make use of them. For now, Gollum suits me as a simple, free alternative to Confluence. Notion is obviously a far more powerful product.
Guix seems interesting but I almost stopped reading when I read "Nix". For all the benefits the Nix ecosystem provides, they haven't crossed the usability gap for me. First was naming their packages so confusingly, Nix the language vs NixOS vs Nix the package manager. Then there's the whole promise of it being usable from multiple platforms ("you don't even have to use NixOS, just use the package manager for awesome builds") -- It was supposedly amazing for building some software packages, but the reality was always so sticky and never quite panned out.

To be fair I have seen/heard lots praise it a lot for delivering stability to the servers they manage, but in this day and age, I'm not sure it's even worth trying to learn something to manage servers when the cattle approach is so much better (just shoot it). Even when stateful applications get involved, distributed storage is springing up to make it easier than ever to take down a server but have the data it had still be accessible, granted it was replicated, and sync if/when the machine ever comes back up. If the world evolves in that direction, it seems like people will only care about packages at VM/container/whatever base layer build time.

Don't want to be the downer here but I don't think it's likely that Guix is going to cross the usability chasm. I've invested a lot of time/interest/effort in projects that were better, but never crossed the usability/mindshare chasm and while I hope I'm wrong, this feels like some of the other ones.

Completely unrelated to that though, this quote rang true to me:

> Guix is a fork of Nix and addresses the main issue that Nix didn’t get right: instead of comming up with a homebrewed domain-specific language (DSL) with its own set of limitations and idiosyncrasies, Guix uses a full-fledged programming language. (And a good one at that, since it’s Guile Scheme, a Lisp-based language.)

I think Hashicorp has this problem with HCL (see the recent updates[0] announced at the last HashiConf, the `for` keyword is now in HCL) -- though I'm not recommending they fix the problem with lisp, people need to stop making DSLs then bridging the gap between their DSL and a full programming language. I much prefer the Pulumi[1]'s approach -- though it leaves devs lots of rope to hang themselves with ("recursive infrastructure building functions...why not?").
