I'm in my mid twenties, and having never touched a piano before, I got a Roland FP-10 two months ago.

I'm slowly clawing my way through a music theory book, but I've already learned some tiny pieces of music on the side (like the beginning of Strobe by Deadmau5) and it's stunning how fast one can get from "absolutely clueless" to "hey that sounds like music".

It's enchanting and wonderful. Sure, music theory can be annoying there are many weird and semi-arbitrary rules about how things are called and there's lots of historical baggage attached to everything, but as soon as you touch the keys, everything just fades away. Man, you can pour so much emotion into that thing.

So if you find yourself (like I often did) thinking about how cool it would be to play the piano, but it's probably hard and it's too late and there's no time and you wouldn't even be a good player... Do it. It's easier than you think and YOU CAN do it.
> Just compare against a different strong currency to see how fragile the USD is

I just did. What are you talking about? Please link me to graphs.

> My USD loses value every day, while my crypto just grow.

I have a good amount invested in crypto, but look at the chart man. We are in-or-approaching bubble gain% levels.
> In distributed computing

I didn't mean distributed computing, I meant distributed through the program. Not all programs actually have a hot loop.

> When optimizing the hot loop only, it can be quickly written in Cython or C, since the scope is usually a lot smaller, so no need to use Go.

That assumes proficiency in C, and it still complicates building / bundling / shipping a lot, the first bit of native code into a Python codebase is a huge investment and a significant step back in convenience in many ways.
Umm, Dan Ackroyd?

https://en.wikipedia.org/wiki/Dan_Aykroyd says:

"Since childhood, [Dan] Aykroyd has struggled with symptoms of Tourette's syndrome and Asperger's syndrome."

"He became the second member of the original cast to host SNL in May 2003, when he appeared in the season finale."
There's a big difference between knowing the country of origin, and knowing the whole journey of the product, right from the farm.
Have any of the developers noticed the fundamental fallacy in the answer? The question is not about parsing, it is about recognizing a token in a string, which is exactly what regular expressions are designed for.
> but because cancer has already killed a good chunk of those most susceptible

Why do you think that?

Death rates for cancer continue to trend upwards by age: https://www.cancerresearchuk.org/health-professional/cancer-...

If your “hypothesis” were correct, the rate of death would decline after the early fatalities occurred.
Yes, the NYT seems to have lost the ability to treat both sides of an argument skeptically. Disappointing.
Exactly! Sometimes my recommendations are good, with long form tech and history content I actually want to watch. But click on one Top Gear clip and that's all out the window, and I have to actively recall what these channels were called and try to build them back into my recs.

There was a time a couple years ago I watched one episode of Arthur for nostalgia purposes and it completely obliterated my recommendations. I scrolled for hundreds of videos and didn't see a single non-arthur one. It took months for the site to become usable again.

> I need to have a very high income and maintain it during the length of a 30-year mortgage

Not short-term helpful, but keep in mind that a mortgage only ever goes down due to both refinances and inflation. So the first few years are tough but it can only gets easier. So you don't need to maintain high income for 30 years.
Note the relationship between the size of the team and the ability to manage a monolith.

A team that grows larger quickly needs some way to manage the complexity within the codebase and the difficulty of knowing whom to talk to. In theory, it is possible to build a modular monolith with clear ownership boundaries. In practice, this requires strong technical leadership.
Any chance we've got time for the meta question.. Does anyone have a clue why prion diseases are so popular on HN at the moment? AFAIK it's not something that often turns up in mainstream media? Not even as something they keep in the 'slow news day' draw..

Are we genuinely scared by the idea of getting a prion disease? Is there an actual risk of a prion epidemic? ..or putting my Freud hat on, does everyone on HN share a weird masochistic fetish about 'the next big pandemic'?

For my part I don't really get it, but then maybe it's because I'm british and for us prion diseases have been boring (or rather the news isn't interested in prion diseases) since mad cow disease stopped being a thing 20 years ago.
The first bulb you linked consumes 2.8 watts and produces 250 lumen.

The Dubai one consumes 1 watt and produces 200 lumen, that's more than 2x difference in efficiency.
You have the timeline wrong.

They failed for multiple reasons:

> With tight creative control of ads, an insistence on taking a 30% cut of all ad revenues, and a prickly attitude to sharing customer data, the platform won few fans in the media industry.

But iAd launched before their "protection of user privacy' stance. Not after it.

= They couldn't monetize it, so only after that they attack it and "protect user privacy".
The question is not about parsing at all. The question is about tokenization of XHTML. You can tokenize XHTML with a regular expression.
51% attack... They could change confirmations or be forced by the government.

Governments can't do that with transactions through banks.
>Everyone knows DOGE is a joke

My gf didn't. She found it on Robinhood and keeps calling it a "stock." The main reason she bought it was because of something Elon Musk tweeted and a bunch of her friends did too. I've always been pro cyrpto currency but this freaks me out.
Can you give examples? To be clear I don't mean programming environments that a tech-minded 10 year old can learn on if he doesn't have a PC, I mean tools to let non-technical users program their devices (hypercard probably the best example I can think of)
Falls apart a bit if you're trying to nail down chemistry or something like an IC production process though where the equipment itself is built by people who will neither talk nor possibly sell to you.

Turbine blades are like ICs in the sense that the secret sauce is in the materials and the manufacturing processes. You can imitate the exterior shape perfectly and it still be completely useless.
Why would this be surprising when the definition of tree is so:

> First, what is a tree? It’s a big long-lived self-supporting plant with leaves and wood.

I have some vines that are clearly capable of wood formation and sometimes seem to do so at places for reasons I can't understand.

“tree” is clearly a horizontal classification; it is as surprising as as that not all animals that can fly have common ancestors that can.

> You know birds? Imagine if actually there were amphibian birds and mammal birds and insect birds flying all around, and they all looked pretty much the same – feathers, beaks, little claw feet, the lot. You had to be a real bird expert to be able to tell an insect bird from a mammal bird. Also, most people don’t know that there isn’t just one kind of “bird”. That’s what’s going on with trees.

I do not find trees looking similar at all.
No, I mean refuse to review for any journal that isn’t open source?

You said not reviewing for predatory journals, so apply that to journals that Elsevier owns?
Though without the killing and forced sterilization people assume when they hear the term "eugenics".
What I don't like about statements of this kind is that they're couched in apparently careful language of "being associated with" while implying that mushroom consumption reduces cancer risk .. i.e. a causal mechanistic connection exists between them.

If we make that jump ourselves, they can weasel away with "we didn't say that". But then what are they exactly saying? "We just say it is associated with"? .. so if I am supposed to use this information correctly, how should I go about it? ... No I can't do anything with it .. except maybe if I'm a doctor assessing the cancer risk of a patient and I ask "how many mushrooms do you eat per day?" and use the result to adjust the risk. The patient may just ask back "what kind do you use?".
Where are the major inefficiencies in the supply chain at the moment, from your perspective?
Funnily they refer to some people wrongly using "Gnuplot" instead of "gnuplot" yet they use "Gnuplot" 23 times in this FAQ.
Thanks for this post, I've been struggling to learn how to play piano for few years now.
Gosh, seems like that might have a chilling effect
Kids who only had a summer job in high school definitely had a leg up. More time to study and more sleep.

And point number 3 is dead on.

This goes back to the point that it is important to be able and willing to work hard but working smarter is a better overall strategy.
Thing is you can delete it immediately after you've set up your account with alternate 2FA eg TOTP/authenticator.
So you're using CLJS for the backend?

Also, can you explain what you mean with the following:

"with Clojure/Clojurescript, I was able to make something I could only dream about before."

What does CLJS enable you to do that you can't do with JS / TS?

PS. I'm in a somewhat similar boat, i.e. not a great programmer (not my job anyway) - more of a prototyper - hence my interest in your experience with CLJS.
it is so strange how things evolve in parallel in various fields. We used to love object oriented modeling with inheritance hierarchies, until the point we realized how it was so hard to have any hierarchy perfectly match a given domain.

Then we moved to composability + interface, realizing it's easier to compose attributes (often related to a given set of functions) to make any graph of structures instead of just a tree.

Just two days ago looking at how virus recombined themselves in the most random ways, i wondered if the species classification of the previous centuries based on trees were not destined to follow the same path.
Thanks for that link, I was aware that Stalin was responsible for a famine resulting in millions of deaths, but had no idea of the details
That's smart. Didn't think about it!

Though, the emitter is pulsed and I also rely on the fact that it stops resonating after I cut out the power. Unless my LC oscillator has a low Q, it will keep oscillating after I cut out the supply, which is something I'd prefer to avoid.
I find it a bit hard to believe that the mass current calculations for the bullet cluster have even been made. How can I convince myself that they have?
the 'at the moment' probably explains it - a lot of online fora have, for want of a better word, fads where there is a lot of discussion of a particular topic for a brief while, then it fades and sooner or later a new topic comes along. I quite like the phenomenon personally.
That's not a question?
I'm thinking it's a figure of speech as well. I couldn't find said review elsewhere and it wouldn't make sense to leave one on Glassdoor anyway. It's a noncommercial open source project.
Makes me wonder how no one has sued that company for false advertising yet - when the CEO says "this car you're buying is capable of doing X and will do it by the end of 2016" but it still doesn't in 2021.

Tesla seemingly gets off the hook rather easily regarding this stuff anyway, wonder if that's just because they have Musk at the top.
In my phylogenetics course I learned that “rooting” a tree can be rather arbitrary. What you get is not a hierarchical structure, but rather links between different species.
The whole lore is undoubtedly nihilist, because it started in times and places where nihilism was a survival mechanism: Thatcher was gutting half of England, nuclear holocaust was on the card, greed was celebrated, and for many it felt there was no escape from a very grim future. Games Workshop took the “heavy metal” way out: everything should be grotesque and excessive, the “men in charge” are all equally bad, what matters is cool equipment.

Instead of criticizing something that helped people endure that time, maybe you should ask yourself why its popularity ebbs and flows but is still so attractive to so many. Maybe we do have to choose between following equally-terrible people, every day? Maybe we still feel powerless to stop never-ending conflicts? And maybe we just like doing cool shit for the hell of it.
> The slow tempo loses you mental oversight of what you are trying to play.

When I was a drummer, I used to think that too, but it turned out to be false most of the time.
If I really wanted to make something sound good in a fast tempo, I had to make it sound perfect in a slower tempo.

My teacher used to say "if you can play it fast, make sure you can also play it slow"

But, as always, it depends.
Why are we so bad at naming things
On average I work between 4.5-5.25 hours per day.

I divide my working time in 45 min. sessions with 10 min. breaks in between. To be honest I don’t always take the breaks, which is wrong and is something I need to improve. During a break I stand up, do a chore at home or go to the balcony.

In the course of each 45 min. session I do only work with little to no interruptions. No casual Internet browsing, no mails and I try to avoid chats. On average I tend to do 6 to 7 session chunks per day which is more than enough to implement features, fix bugs and write documentation.

Distractions. Avoid the ones under your control (reading news, procrastination) and embrace the ones out of your control. When you get a sudden phone call, instead of going directly back to coding, you could read/write mail or answer some work chats. Such activities also count as part of my sessions.

No one is there to supervise me, so I need to be _honest_ about the time I dedicate to work in each session. In the end, I exercise self-control to the best of my abilities. I could also do 3 work sessions a day and still get paid, but I don’t believe this is in my favor. Doing more is OK, but I hit a cognitive limit sooner or later, so I only push myself when it’s really needed.

When I need to learn new stuff, I do it mostly in the mornings. Memory works best after the brain had some sleep.
Humanitys history was a brutish thing. And it seems to become one again.

The last great crisis due to our exponential consumption nature is barely 80 years in the past.
And baring some "miracle" class science breath throughs, its bound to return.

Not saying the future will contain catholic-nazi-space-marines, but life might become brutal and short again, if there are no major breakthroughs in energy production.

Engaging with that expected future brutishness is basically just fitness signalizing at this point.

> Your mortgage payment can go down quite significantly over 30 years while paying rent will go up quite significantly over 30 years.

Very true. This is the key that makes buying so attractive.
My (admittedly, very layman) understanding is that prions are proteins that are misfolded in such a way that when in proximity or contact with their 'correctly folded' version can induce them to change shape to the misfolded version. Prions are below the level of things like viruses or bacteria -- they are a result of the underlying chemistry of making proteins. Proteins and their folding is arranging atoms into energetically favorable states. A prion is then a different arrangement of the atoms that is somewhat more energetically favorable, one that can induce other proteins to transition to this different state. It is this last property that makes them infectious.
Dyson spheres would glow in the mid- and far-infrared (re-radiating energy absorbed from the enclosed star), and so would not be "dark".
A little bit further down he explains it's just a self-diagnosis. I think the implication is that Elon is formally diagnosed

To be fair, they mostly advise against GNUplot, and mention Gnuplot because of the aversion to start sentences with lowercase (which is also where they use it with uppercase).
> So why didn't the black grasroots ever sprout an analogous new rock scene, instead of turning towards the mainstream, big stage, light show, for-profit music that comes from black artists for the last few decades?

When hiphop evolved, rock was the premier mainstream, big stage, light show, for-profit genre. I’d argue that, insofar as rock & roll “died”, a more succinct explanation than the article’s is that: it became popular, controlled by big business, and ossified.

And because of that, it ceased to be the voice of the outsider, which hip hop became. (Of course, as often happens, the energy, diversity, and rawness that comes from being the voice of the outsider led to hiphop becoming broadly popular, so now it is thr mainstream, yadayadayada... But it became that at a time when industry gatekeeping isn’t as powerful, so maybe it won’t ossify under elite control the same way. Time will tell.)
They are absolutely lazy monopolists in my view. They are still selling the TI-83, a device released in 1996, for $112 at major retailers.
Kelsey Hightower, a core Kubernetes engineer, once said that microservices were created because teams didn't want to talk to each other. One problem - they still have to talk to each other.
“ 1.1 What is gnuplot ?

gnuplot is a command-driven plotting program. It can be used interactively to plot functions and data points in both two- and three-dimensional plots in many different styles and many different output formats. Gnuplot can also be used as a scripting language to automate generation of plots. It is designed primarily for the visual display of scientific data. gnuplot is copyrighted, but freely distributable; you don’t have to pay for it. You are welcome to download the source code.”

If it’s lowercase in title font, it should be lowercase everywhere.
What I don't get is why they didn't pitch it as Dubai only for first year then global.

Proteins are produced as a string (either literally as a chain molecule, or in the computer science sense of a string of characters/amino acids).

Once a protein is formed in the body, it naturally folds into its useful, functional shape with the purpose it was designed for.

A 'misfolding protein' is then a folding into a stable shape which is not desired.

A 'prion' is a misfolding protein that encourages other proteins of the same type to misfold in the same way - maybe by acting as an incorrect template for folding. When this is folded in a way that is difficult for the body to break down, and somehow enabling its sibling proteins to do the same, you start to have problems.

So, a prion is a protein structure able to reproduce itself, in some way. Prions are not 'viruses', where viruses have their own DNA (or RNA) for making their own proteins.

There's an argument about whether viruses are 'alive', since they depend on others' cells to make their proteins. Prions are even less considered 'alive' - they are just inert single protein molecules folded in a particular way. But, they have the ability to reproduce, in some sense.

I'm criticizing it for being a vehicle for thoughtless Space Nazi roleplay.
I was a huge believer in Monero.

Maybe I still should be. I invested heavily into it years ago because most of the actual uses of cryptocurrency benefit from the privacy advantages of Monero.

I've sold out now. The truth is that since Monero came out, it has become much, much easier to wash or launder all other coins. I think long-term this is going to hurt its value. We're going to see long-term consolidation into a few main cryptocurrencies and there will just be a button in the wallet software that swaps all your coins or washes them using some crazy cross-chain technology or something. As an example, you don't really need to hold monero to benefit from its privacy advantages. Just sell your ETH into monero, move it between a few wallets, then sell it back into ETH. This could be done automatically.

So idk, I'm less bullish on it now even though I used to be a diehard fan.
It’s not just a misfolded protein, it’s a misfolded protein that catalyzes other proteins (with the same chemical structure) to misfold. So proximity of a “good” protein to a “bad” protein is sufficient to turn the “good” protein “bad”.

It’s an interesting hypothesis to consider that there could be other prion variations out there that misfold other types of proteins, but they don’t misfold the “good” versions of themselves, so they don’t self-replicate and instead just create one-off instances of a broken protein.
The non-locality of QM was introduced because of the Fourier transform which is non-local. Mainly because it's the easy way to calculate by hand when you have no computer in the 1920s.

[Tinfoil hat warning :] Since then it's a self-reinforcing confirmation bias to avoid the obvious locality of the real world mainly because of geopolitical reasons in the 1960s. /[Tinfoil hat warning :]

Fiction, enrages those engaging in religion, in fiction made real. Cause if tolkien could create LOTR, then the bible could be written by a nerd in the dessert, thousand years ago and all that remains of god is the Greatest Octalsided Dice.

So no wonder fiction also enrages believers in societal fiction.
I think the situation is complicated. For hobbyists it certainly seems like the situation has gotten much better: there's lots of well supported, cheap microcontrollers and little boards for people to play with. But I think for the average user, the situation has regressed. I've heard of many an engineer who got into programming because they played around with BASIC and system extensions on their home computer, because those systems were open and easy to get started on doing that sort of stuff. These days, a child's computing device might be an iPad, or a Chromebook; they're certainly fine for getting work done, but they don't feel like they "invite experimentation" in the same way as systems of the past might've.
