> Has someone here picked a musical instrument seriously for the first time in their 20s and managed to self learn? If yes, it would be helpful if you could point to resources that were helpful to you and any daily practice schedule you followed?

Self-learning piano is, overall, a boondoggle. You want a teacher.

I started learning piano in December 2018 at the age of 27.
For the first couple months I stayed on my own to build up at least some base knowledge before getting a (remote) teacher in April 2019. I mostly used a service called Flowkey (sorta like Synthesia for the web), the book Music Theory for Dummies, and a course on Udemy by Ben Westenra.

I highly recommend getting a teacher, even remote, using a site like TakeLessons.com. They'll keep you motivated, answer your questions, and set accomplishable goals.

> I have tried learning piano and I found a lot of stuff irritatingly hard to get right and got bored. Like for some reason I am not able to transition to other keys well when I am using both hands or when some finger involuntarily moves because of motion of neighboring finger.

Cumulative hours of practice are necessary to learn even a single piece, and short of Matrix-style skill uploading, there's no shortcut to putting the time in.

> Also, I seem to get finger fatigue which is surprising considering the amount of time I spend on keyboards anyway.

Not all keys are the same. :) Your fingers are getting a much different and more intense workout by playing.

Edit- Updated language since someone focused on pulling a "gotcha" on me for upvotes over the context (in this case, piano.)
A personal IP address is PII. The same for a license plate. At least under GDPR.
Oh okay, I use FF. This must be why. I alt+tabbed 100+times and didn't experience the issue. Didn't edge tabs now recently show in alt+tab? I wonder if it's because they are surfing between two tabs and alt tab is showing the last tab they clicked on rather than the last window they had up.

FF uses CTRL+Tab to cycle through tabs like alt tab.

I read everything completely differently.
Another rather substantial difference is in M2 matrix of Oklab. In my experiments I don't see S-participation in colors with high spatial frequency. Because in image compression a lot of information is in high spatial frequency, one gets favorable image compression when M2 matrix is without S contribution in Luma. We use just [b b 0, a -a 0, -0.5 * c, -0.5 * c, c] in the M2 phase in JPEG XL. The two 0s there don't bring S reception into Luma and redness-greenness observations.

This difference can be because Oklab is based on XYZ which is based on 2 degree color samples. XYB is based on about 0.03 degree color samples. Perception seems to be different there -- to me it looks like S is not yet integrated into Luma experience at that resolution.

In butteraugli color modeling is more complex: it is divided into high spatial frequency and low spatial frequency. S is brought only to the low spatial frequency color transforms. (Frequency separation there is by Laplacian pyramid.)

because then the people are generating value in the economy instead of just consuming it; which is objectively better for society. People get paid to do work because it is of value to someone, so the more people who get paid better to do things that other people need done, the better off everyone ends up.
There was something similar in the UK. The upshot was be careful if you are crossing the road when a BMW is nearby.

Why is keyboard use the pinnacle of UI? Pretty much every device has some kind of mouse-like device attached to it, and trackpads with good scrolling (e.g. Apple ones) are a wonderfully intuitive way to control movement.

I get that HN likes using the keyboard for stuff like terminals, I do too. But web pages aren’t terminal applications.
Ok, but then I'm genuienly curious - which laws are being broken? Licence plates in the UK can be scanned by automated machines owned by private companies, that's been established many times before. To request the owner data from the DVLA you need their permission - but that's not necessary here, BMW doesn't need to know anything about the owner, so no such request would be made to the DVLA.

Then on the other side, they have a database of cars that they sold and which are still under warranty - again, nothing about owners, none of the silo'ed personal information needs to be accessed at all. If the car is not on the "warranty==true" list, then they show the ad. I assume the ad doesn't display anything like "hey john smith, your warranty is expired!".
Wasn't In Rainbows famously released as a surprise and thus had no real hype built up to it?
I don't think you were rude in the bug report, but I think there's an issue where if something is described with lots of brevity, even if accurate, it's hard to know if what was said is really what was meant, since there's enough bug reports that aren't careful about their language that you can't really trust someone when they just say "it just hangs". So in that case a more detailed description/picture/whatever of what exactly the error looks like is helpful even if technically it can be described in one sentence
Be aware of variable frame rate footage, make me aware and have clear ways to deal with the issues. Adobe software lets you screw yourself with this, it’ll import fine, not warn you but then your exports will have seemingly random weirdness like flashes of green for single frames that’ll make you think your hardware is failing.

Use as much power of my gpus as you can, if I have a high end nvidia gpu I want to see it acting like a hot knife through butter.

When I drag footage in a timeline update the display, Premier shockingly doesn’t do this.

Reload footage button, another thing Adobe Premier doesn’t have.
> Most religious books that have stood the test of time have lived up to the hype.

They really haven't. Not a single one of them. There is, however, organized religion around them that has twisted those book to mean whatever it is that brings the flock.

Are they influential? Yes. Have they stood the test of time? Hell, no
Those customers are probably using it in some of their services. I’ve worked with a number of enterprise companies who are moving to the cloud and most of them have never considered something like front door to route their traffic.

I’ve brought Front Door into their architecture for the services I was working on, but even if they decide it’s a great thing for the entire company to use, it will take them over a year to get security to approve it, and then multiple years to get it rolled out to all of their products.

With Azure’s core customer base being major enterprises, it’s not surprising that you had a hard time finding evidence.

The results almost certainly vary by region (because regional traffic, weather and economic conditions impact who buys what).

Measuring aggressiveness is going to be a measurement of outliers. For everyone weaving through traffic in their BMW without turn signals there's a gray hair putting along. For every Tacoma clogging up the left lane there's a Prius taxi hauling ass to the next fare. I don't think it's a very informative thing to try to measure.
Let me recommend reducing the number of decimal digits in your published forward matrix to 4 or 5. There's no way the extra 5 digits are making a practical difference here, and they make it a lot harder to write down in a visually compact way.

Do it soon before you have too many people creating independent implementations.
I really wish personalized ads were criminalized. Lets go back to contextual (by location of ad) and general ads. The stalker big brother ad industry needs to be stopped.
Maybe I've just missed it, but I have found pkg-config difficult to use and poorly documented. It's fine if you are installing things with a package manager, but I found it took some trail-and-error to figure out how to do this for my own lbraries, or for things built manually from source.

Also with c/c++ style system dependencies, I feel like there are a lot of issues with things like version conflicts which are solved much more simply by a package manager like cargo.

I agree that it's functional, but to say relatively easy I think is a bit of a stretch.
Yeah, both of those are good recommendations!

I also think it is useful to focus on understanding the various experiments that have led to the different color models. The most important one is the experiments that led to CIE XYZ. Lecture notes from universities seem like one of the best sources of info about the basics. Such as this: https://www.cl.cam.ac.uk/teaching/1516/AdvGraph/02_Light_and...

Other experiments that are interesting, but a bit hard to find information about are:
The Munsell renotation effort in the 1940s, the experiments that led to OSA-UCS, the MacAdam ellipses.

I also like this paper since gives a fairly good overview and lots of new keywords to search for: https://www.osapublishing.org/viewmedia.cfm?uri=oe-25-13-151... (and is freely available)
It would be pretty maddening to keep losing the application you're working on because of the infinite scroll.

In RTS games you have keyboard shortcuts to return to your unit groups, bases etc to mitigate that, but there you're supposed to jump between points of interest while for general use you tend to keep the same point of interest for a long time...
Out of my head:

* Obama: Libya (in ruins), Syria (in ruins)
* Bush: Iraq (conquered, then partially reconquered back by ISIS), Afghanistan (yet another never-ending Afghan war)
* Clinton: Serbia (ended up relatively OK, had to elect a new president, give away the old one, and also a part of the country declared independence), and I think there were more? I was a kid back then, don't remember it well, need to wiki up.
* Old People's Bush: Gulf War, and I guess wiki would tell more stories.

These all are large conflicts with non-trivial outcomes. Lots of troops involved, lots of casualties caused, serious consequences for the countries attacked. Now, what are the casualties for that T's conflict with Iran? What are the consequences for Iran?

Checked wiki [1]: 7 combatants dead on the U.S. side, 22 on the Iran side (of which 19 is friendly fire), in the grand scheme of things - no consequences so far.

Also, if we need a relatively neutral third party, then English Wikipedia calls these events not "war" but "crisis" [1] and does not list it in their list of U.S. wars [2]. Feel free to try to add it to that list and prove your point to fellow wikipedians, I'd watch how it would go.

Deadwood: The Movie
I think it was even more divisive than the first season. I found a lot of people who loved the first season weren't sold on the second. I wouldn't expect it to go down well with the HN audience.
Note it's by shivers, not pg (who I don't think was involved with T). It is worth reading the whole thing.
Exactly, they’ve gone for luxury but not as well as MB or Audi who are now eating their lunch. To say nothing of Porsche taking the sportscar and sporty SUV market profits. CarPlay subscription is just offensive.
The Internet becoming mass market. In the early to mid 90s there was a lot of very recognisable hype about online shopping, TV streaming, use of it for phone/video calls etc. And a lot of skeptics too.

apart from some lunatics, no German person denies the Holocaust and this has nothing to do with "reprisals" and everything with proper education. The memory of the Holocaust and the Nazi era is omnipresent in Germany.
kids are also a pretty good indication. if for some reason my model 3 is not parked where it's usually parked, the kids of the neighbourhood come over and ask where the Tesla is. i'm not joking. nobody ever cared where my previous bmw mini, vw golf or land rover parked.

I'm no fan of the design, but BMW has considered their "kidney grille" to be an iconic design element since 1933. https://www.bmw.com/en/design/the-bmw-kidney-grille-through-...

In general, sentences of the form "(I heard from (?P<authority figure>.* ) that )?(?P<bogeyman of the year>.* ) is (?P<influencing us in unseen ways>.* )" should be treated with a great deal of suspicion.

I used to think like that, but have eventually given up.

SVN is easier to learn and much more intuitive to use. But even if you're not a power user you get to its limits quickly. (E.g. svn afair does not support bisecting by itself, though there are external tools.) Given the world uses git you inevitably will have to learn git if you do anything with software.

In the UK private companies are allowed to scan licence plates though, literally every single supermarket car park has AMPR cameras which record when you shop there. There's usually a plaque somewhere that says "by entering this carpark you allow us to use information about you".
here's my casual point of view as a gamer who likes to sometimes capture gameplay and upload to youtube.
My biggest pain points are that all the good video editors are paid, and the free ones are total crap.

Here's what i need from a video editor :
ability to cut/copy/move video across timeline

add/remove audio tracks and adjust their volume + mute certain parts

apply cool transitions here and there

add text overlay and text frames

and all this without the 1000 knobs and buttons in the pro editors, and without the buggy and ugly free editors

I would pay 10-15$ for such editor per year. After all it's for casual use. anything more than that and it would make me wanna pirate it.
I watched this for the first time last week and I was surprised that the plot has remained pretty novel. It's one thing to watch an old movie and recognize it for first producing a certain story (or at least capturing it on film) but I can't think of a similar story to Casablanca and that impressed me.

It was also neat to see the film shot just like a play where there are very particular sets each scene. I wish I could have the scene the original play once.

A few things I didn't like though was the flashback. There was no subtlety and poor writing. They could have started the film with their time in France. The real plot point wasn't that the two characters knew each other but _why_ she left him.

And it was also odd to me that the general was in his headquarters when he learned about the escape attempt but then showed up at the airport... without any men.

Anyway, I did enjoy the movie and am grateful to it for introducing As Time Goes By.
The stock market hype during the beginning of the pandemic.
M2cs or M5c are still by far the best cars in their class. While I'm not a fan of BMW's new design language (think the 4-series, or the iX), nor their move to subscription-based features, it's still my go-to brand. Other (non-exotic) brands are either downsizing (2.0 engine in the new C63 AMG for gods sake) or going fully electric – and I like my v8 rumble in the morning.
I don't really follow this article; it makes little sense to say that privacy is anything but a defensive tool.

The issue with privacy, and the reason it has such an image problem, is that society can be split up into 3 groups:

* People who believe authority figures are fundamentally acting in good faith (large majority).

* People who believe authority figures are acting in bad faith (substantial minority)

* People who want to deploy authority to make others do what they want.

Group 3 want privacy to have an image problem, and they are persistent in their attacks.

Privacy is a tool for the second group to convince the first to coordinate with them. The first group won't accept arguments that authority figures might potentially act in bad faith. Therefore, the argument must be made that people have fundamental rights to privacy that a good faith authority figure will not want to infringe.

It is a matter of taste what people want to believe the % breakdown of society is into those 3 groups, but try going in to a discussion arguing that authorities might in the future act in bad faith. It is remarkably difficult to carry a debate with that frame despite substantial evidence.

Not sure why BMW gets so much negativity. The past models of BMW were really boring. The design wasn't extraordinary that it could compete with Audi or Mercedes.

But the new design of the iX and 4er models are very beautiful. I must say the new grills really appeal to me.

It seems that the new design causes a similar reaction as Mercedes SUV design of GLE and GLC (Coupe). Mercedes took a new approach and got a lot of negative comments. But ultimately they set a new trend and their SUV's were a huge success.
That is based on CIELUV, which is one of the spaces tested against in the article. CIELUV is useful because its chromaticity space is a projective transform of XYZ. That also means it doesn't predict perception of hue as well as more complex models.

> charging a subscription for Apple CarPlay

Well that's a scam if there ever was one. Who wants a subscription for basic functionality in a car? Might as well buy an iPad and solder it over BMW's control panel.
It came out of nowhere and nobody ever expected Valve to come back to the Half-Life series.
> I'd say Avengers: Endgame

It really didn't. "Let's take a compelling villain and a nice-ish philosophical dilemma, create a world that's reeling in the aftermath of said villain's actions... and just quantum time travel kill the villain with no effort and literally exactly zero consequences for anyone involved." Oh. Right. Boohoo exactly one single character died with exactly zero consequences for anyone because his contract with the studio ran out.
Oh nice, that's good to know, thanks!
The biggest hassle with svn is adminstrative overhead. You need to give developers access. Git completely works around this hurdle.
Hmm, never thought of it that way.

Person your responding to isn’t asking about that particular color space. They’re asking for some real-world examples. This is a very theoretical piece about color spaces that intersects with a very particular use of color spaces.

YCbCr was definitely not designed for analog tv. That color space is for digital video and imaging
In my 2016 BMW, CarPlay was so incredibly buggy. Unsure who's at fault on that, but the thought of paying a subscription for it makes me chuckle.
I was with a fortune 10 company as a tech executive, we had an effort to move all of the call center technology over to web based technologies in a modernization effort. The call center lost over 15 million dollars in revenue in the first week when we moved from the old UNIX terminal app to the web UI, after an extensive study it was deemed the issue was loss of speed due to lack of keyboard shortcuts and navigation. For power-users keyboard shortcuts allow them to navigate and use the app up to 3 to 4 times faster than a mouse based interface. If you ever watch a 3D artist work in Max, Maya or Blender this becomes evident quickly. It is not that keyboard use is the pinnacle, it is that in high use cases it saves time and money.
Never is an awfully long time
> But we're presumably talking about two types of performance:

Agreed, and you only need to look at C++ linkers for proof this. LTCG can take minutes (or even hours) for marginal gains.

That said, this entire article is about migrating the development builds and still being painfully slow. The links I shared to esbuild point to building release-able bundles, I.E. "Optimised". And let's be honest, the optimised bundles here (i.e. the output of webpack) aren't performing inlining, constant folding, expression simplification, dead code analysis, or anything of the sort, they're doing some fairly rudimentary file IO. Only the most invasive optimisations (whole program optimisation) should explain the orders of magnitude of a difference.

The reason they're slow is because they're written in JS, single threaded, with no considerations for performance. As esbuild has proven, rewriting in go with consideration for perf can provide a 100x speedup!

> but realistically does it exist right now?

Yes, it does it's esbuild and I linked to it in my comment above!

> That's probably a trite/obvious argument, but it's worth mentioning nonetheless.

Honestly it's probably the truth but it's insane how we've managed to get here!
