wrigby··on Spotify hit with $1.6B copyright lawsuit
Yeah, saying HFA is ill-equipped to obtain mechanical licenses doesn't make sense to me. That's exactly the role they play.

Maybe they didn't obtain performance licenses though?

wrigby··on Spotify hit with $1.6B copyright lawsuit
This is a bit confusing. My understanding of how music publishing works is that the copyright is usually assigned to the publisher (for a limited amount of time), so any rights of the copyright holder are rights of the publisher. They wouldn't have to explicitly assign litigation rights to the publisher.

Disclaimer: IANAL, and with big artists, publishing deals can be very very different from boilerplate.

wrigby··on OVH outage explained
My understanding is that it's the diesel engines that don't like it (the generator head itself is fine). Basically, some of the fuel in the combustion chamber doesn't get burned, and comes out the exhaust. This builds up in the exhaust system, forming an ooze in the pipes. I think it's worse on a turbo diesel, because now the ooze is coming into the turbocharger.

wrigby··on HTTP 103 – An HTTP Status Code for Indicating Hints
To further clarify, my intuition (having not read the spec) is that even if a middle-box sent a 103 response and had the client download a JS or CSS file, it won't get used by the client unless it is referenced by the document that is ultimately being loaded.

So yes, the file would get fetched, but no, it can't affect the page being rendered by the browser.

wrigby··on College Advice I Wish I’d Taken
This. I did this accidentally - that is, I didn't move to a new place, because my state already had a system that works really well for this.

The Virginia state schools are very inexpensive for the quality, and I did two years in the community college system and then transferred to James Madison with guaranteed admission (because of agreements between the state universities and the community college). JMU wasn't a noteworthy CS school at the time, but I also had the option to head to Virginia Tech or University of Virginia, both of which have great programs (JMU offered a minor in music business, which is what made my decision).

Tuition was <$4k/semester for residents at the time (class of 2011).

wrigby··on Rowing across the Atlantic in 48 days
I had never heard of a para-anchor[1] before, so I just looked it up - they're really cool! It's a brand of sea-anchor[2] that looks like a big parachute that goes underwater, effectively anchoring the boat where it is without having to reach the sea floor.

wrigby··on Show HN: Paint yourself in the style of classic art, in your browser
Yep[1]! I used it for my girlfriend's small business site (Wordpress) and was very happy with it.

I think CSS, JS, and images are cached - HTML is not.

wrigby··on Show HN: Paint yourself in the style of classic art, in your browser
I think most CDNs will add reasonable cache-control headers as well - IIRC Cloudflare does this with sane defaults out of the box.
wrigby··on Venmo is offering users an physical debit card
That's what I had assumed, but this grammar StackExchange[1] answer seemed to specify that there are exceptions. Admittedly, I didn't read the articles he linked.

wrigby··on Venmo is offering users an physical debit card
The actual headline is 'Venmo is offering users an (ugly) physical debit card,' so the '(ugly)' part complicates this. From a quick search, it seems like 'an' is correct here, because the '(ugly)' part isn't an independent clause... or something like that.
wrigby··on Stagit – A static Git page generator
Looks pretty nice! The readme says it's not useful for repos with >2000 commits, but I wonder if we could hack together some sort of cache for it to facilitate delta updates?
wrigby··on Ask HN: How did you move from IT/software to something unrelated?
I just assumed it was this year, and then I noticed he linked to (presumably) his SoundCloud account in another HN comment[1], which I used as (good enough) confirmation that I had found the right video.

wrigby··on Ask HN: How did you move from IT/software to something unrelated?
You're being polite by not linking, and I appreciate that. However, it's truly good and I think other people will want to give it a watch.

wrigby··on Pirate Bay Founder: ‘I Have Given Up’ (2015)
I'm not 100% educated on the law, but my assumption is that the name of the book is trademarked, but not the story itself. My apologies if that is incorrect.

It's also my understanding that book titles are not protected under trademark law, except for the title of a series, so The Lord of The Rings could be trademarked, but not The Notebook.

wrigby··on Pirate Bay Founder: ‘I Have Given Up’ (2015)
I think this would be more compelling if you demonstrate that 7 years is long enough to generate 80% of the revenue. For many artistic works, it can take years to produce them (writing a book for instance), and many don't gain traction for years either. Film adaptations of books are a great example.

A real-life example: The Notebook (the book) was published in 1996. The Notebook (the movie) was released eight years later, in 2004. With a seven year copyright, the book would be in public domain, and the author may not see a dime from the movie. Is that fair? Is paying the author of the book royalties from the film's revenue a burdensome cost to society? I assert that the author of the book should be able to earn money from the wildly successful film adaptation of his movie, whether he's directly involved with the production of the film or not.

I'm sure there are a lot of subtle technicalities I'm missing, but I think the core of this argument stands.

I'm in favor of reducing the duration of copyright, but I think something in the region of 30 years is a more reasonable amount of time than 7 years.

Regarding the constitution, I think that the means of promoting creation of new works is the ability for creators to profit off of their works. By reducing the potential for profit, you reduce the incentive to create. I can see how overly-restrictive copyright law can inhibit creativity, but I think a 7 year period swings too far in the opposite direction.

wrigby··on More Americans now work full-time from home than walk and bike to office jobs
I'm relatively extroverted, and I can relate to your experience really well after working from home for the last year. The isolation and lack of human interaction can be downright depressing, and I've been led productive than ever.

I'm curious to know if people with families have a different experience with it than single people. I'm a single guy in my mid 20's, and I suspect that if I was married and had kids at home the experience would be more positive.

wrigby··on Pirate Bay Founder: ‘I Have Given Up’ (2015)
I agree that life+70 is too long, but just 7 years seems pretty short. I'm interested in hearing your rationale for choosing that number.
wrigby··on What is a decibel?
This varies from product to product; for example, meters in Pro Tools are labeled directly in DBFS[1]. So are Yamaha digital mixers (at least the LS9 and M7 - not sure about the newer ones).

On the other hand, the Allen & Heath GLD has its meters labeled differently, and I'm not quite sure what they're referenced to (they go up to +12). This can be a bit frustrating, since I never know how close I am to digital clipping, but in practice I aim to get everything around 0 dB on the meters and I have at least 12 dB of headroom.

Wikipedia has a neat list[2] of different analog reference levels for 0 dBFS.

wrigby··on Fifty Shades of Gray Code
Sometimes yes! Wikipedia has a cool picture[1] of a 13-track (and hence 13-bit) Gray code encoder in the Gray Code article[2], which would have a resolution of ~.05 degrees.

wrigby··on Galileo satellites experiencing multiple clock failures
If I remember right, tin whiskers were determined to be the cause in the crazy Toyota runaway accelerator pedals a few years back. I think it's mainly an issue with lead-free solders, which RoHS has forced into widespread usage over the last decade.
wrigby··on Ask HN: If you were to switch career, what would you do?
The rules in my dad's wood shop when I was growing up were pretty simple: any jewelry (necklace, bracelet, watch, rings, etc.) had to be removed, and eye protection had to be on before a tool could be turned on.
wrigby··on Cheap and Painless eGPU Thrills on a 2013 MacBook Pro
Assuming the Thunderbolt 3 device has a type-C female on it, you could simply plug the TB3 connector on the dongle into the device, and use a TB2 male to male cable to connect it to the laptop.
wrigby··on Ask HN: What was your greatest accomplishment in 2016?
I would love to hear more of this story. Would you care to share more details, or maybe write a blog/medium post on it?
wrigby··on Amazon Dash Button's Wireless Audio Configuration
I thought this was really cool, and you don't even need a Dash button to repeat it (just the app). I threw a mic on my desk and recorded the output real quick, and sure enough, it's pretty easy to see the waveform. I was going to post the wav file, but without knowing a bit more about how the Dash links to my Amazon account, I'm a bit hesitant.

I'm going to have a run at reproducing this in Python. Should be fun!

wrigby··on NASA just launched 8 satellites from a rocket dropped from a plane at 40,000ft
IIRC, star trackers are used as both a position and an attitude reference. GPS gives you only position (though more sophisticated systems can be used to determine attitude).

While a GPS outage is a minor inconvenience for most of us, it could be pretty catastrophic for spacecraft if they didn't have another position reference.

EDIT: See below - I was off; they're just attitude, not position

wrigby··on Bose Hearphones
Just bring them with you. Better yet, invest in a pair of better earplugs[1] - they have a flatter frequency response, so the music sounds way better than it does with the foamies.

Most venues will also either give you or sell you (for $1) a pair of foam earplugs at the bar. Do it.

wrigby··on A presentation about optical networking [pdf]
This is an excellent overview of optical networking - one that I wish I had found years ago. As transceivers are getting cheaper, more and more industries are finding use for optical systems. Having a basic understanding of how these systems work can open up a number of creative solutions to problems that were very difficult to solve before.

The amount of throughput that fiber achieves over huge distances is incredible. It's amazing how easy it is to move 100+ gbps between two cities over a single 2-core fiber run.

wrigby··on Windows on New Macbook Pro Permanently Damages Speaker Due to Poor Drivers
I mostly agree on this, but I can also see how they got to a design that has this flaw. You can do better (more transparent, more adaptive, etc.) limiting in DSP than with a simple hardware circuit. Doing the limiting in the driver also saves you hardware components and PCB layout space.

It's a slippery slope of optimization that only works when you control the OS (or drivers at least) and the hardware together, but one slip-up can be catastrophic.

wrigby··on Tesla Shock Means Global Gasoline Demand Has All but Peaked
Oh definitely. I think the point is that the trend in automobile sales is toward a vast majority of new sales being electric cars, just as the trend in phones is towards smartphones[1], and those smartphones overwhelmingly resemble the first iPhone.

wrigby··on Tesla Shock Means Global Gasoline Demand Has All but Peaked
I think the argument is that the iPhone set the trend for what all phones looked and felt like (large, touchscreen-based devices that can run third party applications).

Saying that the iPhone is a small minority of phones is similar to saying that Tesla will have a small minority of vehicle sales, which is undoubtedly true, but doesn't portray the reality that a ton of other car manufacturers will be selling electric cars.
