johncalvinyoung··on What DMARC Protects You From, and What It Does Not
Yeah. I know what DMARC does, I run a mail server, but I thought it might be an interesting blog post nonetheless. It was very very obviously generated text, and not particularly information-dense or insightful. Gave up on reading it halfway through.
johncalvinyoung··on Apple raises prices of MacBooks, iPads
Isn't Deepseek V4 Flash still like 150+ GB even at Q4?
johncalvinyoung··on IP over Lasers
I was going to say, sounds like my college experience decades later. Still a very congested laser link, and I had a headless minitower instead of a rack (though I wasn't a CS student).
johncalvinyoung··on Avalanche Studios NYC Retrospective – An Ambitious Company Ruined
> I could write a lot about why you don’t want to use Catmull-Rom splines for roads.

I would read this essay, and share it with my friends.

johncalvinyoung··on iPhone 17 Pro and iPhone 17 Pro Max
The lack of a black iPhone 17 Pro... has me dumbfounded. I might skip this year.

I'm really happy with the camera features, but there's less differentiation between base iPhone 17 and 17 Pro this go-round. Probably enough for me to still get the Pro, but the iPhone 17 is looking like a pretty cool option this year.

johncalvinyoung··on Ask HN: Why hasn't x86 caught up with Apple M series?
For those like me who wanted to hunt down the linkrotted article:

johncalvinyoung··on It's a DE9, not a DB9 (but we know what you mean)
Whoa, I had that card (or one very much like it). I remember that cursed not-PS2 port especially.
johncalvinyoung··on Show HN: Chili3d – A open-source, browser-based 3D CAD application
Ugh, I wish I could read it but as I'm working in this space professionally reading GPLv3 code is... risky.

Been working in 2D with bezier implementation for our in-house CAD kernel. 3D parametric is limited at the moment, though.

johncalvinyoung··on Dominion Energy's NEM 2.0 Proposal: What It Means for Solar in Virginia
I wish this article recognized that there is a cost to maintaining the grid, both in transmission infrastructure, but also in maintaining the dispatchable generation capacity to smooth out solar's variability. As frustrating as this policy change sounds for consumers, I can see the case that the utility has variable && fixed costs related to net metering that warrants a sub-retail rate of exchange. In point of fact, roughly the rate that Dominion is willing to pay for solar energy in commercial PPAs.

The SREC situation is more complicated. I'm not familiar with Virginia's program, but I could see a case that Dominion doesn't deserve those credits... or one that says if they're building/operating their grid around accepting rooftop solar, some of those tax credits should accrue to their operations. I don't know. I wonder if commercial PPAs also transfer credits in exchange?

johncalvinyoung··on How much oranger do red orange bags make oranges look?
This was my immediate thought when I saw the ring light. Very very likely a CRI of 90 or below, which doesn’t even weight much in red shades. Not uncommon to see 92 CRI with a R9 (red) score below 50% of sunlight or tungsten illumination.
johncalvinyoung··on How much oranger do red orange bags make oranges look?
Not a typical orange. “Sumo Citrus” / dekopon / shiranui is a hybrid tangor/tangerine cross. Very fragile, specialty fruit, only recently available at scale in the eastern US. This is on the high end per-fruit but I’ve seen higher. I usually buy in cases at ~$1.25 per fruit.
johncalvinyoung··on Alphabet spins out Taara – Internet over lasers
As I deployed Starlink in an extremely obstructed spot last year for a few weeks, where multi-second dropouts were quite common... it impressed me JUST HOW MANY satellites they have up there, and just how usable my dish was despite only having ~60% of its field of view clear. It's switching satellites much more often than every five minutes.

The built-in obstruction mapping tool quickly demonstrated that though each satellite represents a tiny slice of sky... over the course of the day you're seeing a vast number of satellites at a high variety of spatial angles and orbits.

I wouldn't recommend that obstructed situation to anyone (and it's going in a much clearer location this coming summer) but the users I was supporting reported it a far far better solution than the 4G LTE they'd been depending on prior. Not a patch on fiber, but a great solution for an awkwardly remote property.

johncalvinyoung··on Show HN: Bayleaf – Building a low-profile wireless split keyboard
less specifically like OP's, but a really great product that I and a bunch of my coworkers use: the 'Ultimate Hacking Keyboard' 60 (typically referred to as a UHK). I have mine with the palmrest and the recent riser accessory, so I use it split and tented for less wrist/forearm tension.
johncalvinyoung··on Show HN: Bayleaf – Building a low-profile wireless split keyboard
I have two UHKs, one at work and one in my home office, and I got my second one with blank keycaps. It's very satisfying.

At this point I'm very happy with UHK's layout and features, but every once in a while I wonder if a low-profile wireless 60% would be cool.

johncalvinyoung··on Boom XB-1 First Supersonic Flight [video]
They haven't updated those predictions publicly in a little while. Definitely a huge setback from Rolls-Royce dropping out, and putting together the coalition that's developing the Symphony engine. Latest I've seen on Twitter is Blake Scholl stating the first full-size engine core should be making thrust by end of 2025.

I'm guessing rollout realistically is more like 2029-2030... but even that is a tall order. Unless, of course, they're a lot farther ahead on Overture development generally than they've revealed.

johncalvinyoung··on Boom XB-1 First Supersonic Flight [video]
Probably optimism talking, but I'd put Boom's chances of bringing to market an airliner capable of supersonic travel at equal-to-first-class-ticket-prices at 60%.

Now I'd put their wilder hopes of eventually taking over the subsonic economy market at considerably below 1%.

But I'm hopeful for that $5-10k ticket to London within the next twenty years.

johncalvinyoung··on Boom XB-1 First Supersonic Flight [video]
Their business model for a long time has theorized that they can deliver an operating cost that would allow airlines to offer tickets at roughly current business class ticket costs, which would be a fraction of Concorde ticket prices expressed in current dollars.

I don't know if those theorized efficiencies will be delivered (a lot depends on that engine) or if airlines will price tickets at that level. But it's the theory so far.

johncalvinyoung··on Sonos CEO steps down after app update debacle
now if only I could find someone making a similarly bad decision. I've been looking to upgrade to a midrange KEF stereo pair. :)
johncalvinyoung··on Pi modder successfully adds M.2 slot to Pi 500
I assumed the OP was eliding that high-frequency circuits and interfaces are notorious for EM/RF noise.
johncalvinyoung··on The lie of music discovery algorithms
This is my experience as well... I have a very broad music taste but with some main themes. I find Spotify's algorithm (11 years of Premium) to regularly surface things I'll like, whether new music from artists I already know, music correlating strongly with known tastes, or every once in a while something that seems out of distribution but I like it anyway!

It probably helps that the strongest areas of my taste are relatively small or niche genres, like Scottish trad and Celtic (folk) rock. In those niches, similar-but-different is often distinctively different in actual experience. Sure, there's covers of the same song from time to time, but I actually do like enough of those not to be bothered, if they bring something new.

johncalvinyoung··on Saint Michael Sword: Are the cathedrals really on a straight line?
Salisbury Cathedral (highest medieval spire surviving in the UK, at 404 feet!) was built on a floodplain close to the river, with shallow foundations only four feet deep. But the prior cathedral had been on a hilltop with much strife over access to water, and at least that would not be a problem at the new cathedral.

https://salisburycathedral.wordpress.com/the-spire/ is a glorious essay on the architecture of that spire.

johncalvinyoung··on OpenVoice: Versatile instant voice cloning
Utterly questionable.
johncalvinyoung··on Gabriel García Márquez: Sons publish novel that late author wanted destroyed
I don't love Moist the way I do Sam Vimes, but the last handful of Industrial Revolution-themed Discworld novels are among my favorites. Maybe it's because I'm a software developer who trained in economics, but the discussions of monetary systems and public policy in satire is much appreciated.
johncalvinyoung··on Nikon to acquire RED
The role of ENG video is not precisely the same thing as digital cinema, though there's some overlap. I remember a lot of indie filmmakers in that era struggling to shoot for cinema with ENG-focused cameras and gear, and often struggling to get what they wanted out of it.
johncalvinyoung··on Nikon to acquire RED
5k for an EPIC-X? Wild. Good thing that that's not local to me, or my bank account would be complaining.
johncalvinyoung··on Autogenerating a Book Series from Three Years of iMessages
This is fantastic. I've done some semi-similar things, have a tool I wrote for generating nice documents from Facebook Messenger conversations, for archiving important personal conversations. But I didn't take it so far as to generate a book yet! What a great idea!
johncalvinyoung··on Meta outage
Note that this status page is... less than helpful in the face of an obvious outage.
johncalvinyoung··on Deploying fiber in the home
Agreed on that. A friend of mine was recently renovating his house on a budget, and I pushed him really hard to put in ethernet. Somewhere on our third discussion, I realized:

- he lives on a 5acre tract in the absolute middle of nowhere. He can see other houses from his, but not many--and subdivision of those properties is prohibited. - neither he nor his family are big gamers or streamers - the best internet service he can get is Starlink, by a significant margin.

In a low-noise environment like that, wi-fi was going to work fantastically well for all his anticipated uses and then some. There was literally no point in installing Ethernet for him, while I've been longing for ethernet for years.

johncalvinyoung··on Things we didn't know about ourselves
oh I looked into that. Conclusion at the time was resolution was far too low to compete with my 27" 4k display on my desk. (I'd love to be able to travel and work remotely without lugging my big display, but my productivity takes a blow restricted to just my laptop display).

From what I'm reading about the Apple Vision Pro, it's not there yet either.

not in California, Iceland, or Japan!
