vatys··on Yes, in the 1980s we downloaded games from the radio
Much later in the year 2000 there was the 8-Bit Construction Set record: http://www.beigerecords.com/products/beg-004.html

It had Atari and Commodore music (as audio) as well as Atari and Commodore software (as data).

Despite the claim on their old page to be the “first use of vinyl for software distribution” they did later acknowledge and reference some prior art in a Slashdot thread: https://slashdot.org/comments.pl?sid=140154&threshold=-1&com...

vatys··on Fort Worth – Now 10th largest US city
It appears to have taken San Jose’s place, from a combination of San Jose shrinking and Fort Worth growing.
vatys··on Artificial Intelligence, Scientific Discovery, and Product Innovation [pdf]
I wonder if the next generation of experts will be held back by use of AI tools. Having learned things “the hard way” without AI tools may allow better judgement of these semi-reliable outputs. A younger generation growing up in this era would not yet have that experience and may be more accepting of AI generated results.
vatys··on Why do random forests work? They are self-regularizing adaptive smoothers
I had the exact same reaction: biology or computers?

The only hint I can see anywhere on the page is "Statistics > Machine Learning" above the abstract title.

I really want it to be about actual biological trees being studied on the scale of forests growing with smooth edges over long periods of time, but I suspect that's not what it is about.

vatys··on Ask HN: What book had a big impact on you as a child or teenager?
I’ll guess yes, since Fahrenheit 451 is by Bradbury. Great list, though.
vatys··on What happens when you touch a pickle to an AM radio tower
Further testing indicated that the taste was neither enhanced nor diminished, but remained ‘‘very much like a pickle.’’ Our conclusion is that the culinary potential of electrical stimulation is limited.
vatys··on The Blue Collar Jobs of Philip Glass
> “I could manage quite well working as few as twenty to twenty-five hours a week—in other words, three full days or five half days. Even after I returned from Paris or India in the late 1960s and well into the 1970s, I could take care of my family by working no more than three or four days a week.”

Would today's youth, even if equally gifted and ambitious, have the same opportunity? I think now there is such a great imbalance in cost of living and pay rates, it may no longer be possible to follow a similar path and get similar results.

vatys··on US Air Force says AI-controlled F-16 has been dogfighting with humans
I don't like this.

While I understand the purpose of HN is to have meaningful and in-depth discussion, and simply stating an opinion doesn't really contribute much, this is something which is so obviously bad and gives such a visceral reaction that the negative opinion outshines anything else I could say about it.

I don't like this.

vatys··on Spatial Computing
Virtually reaching for things far away might be interesting.

I've alway been on the fence about VR, even for games, and never found any experiences to be compelling after a few minutes of fun.

However, one thing that struck me about Half-Life Alyx was the "magic" feeling of the Gravity Gloves in the game. In the game you point and reach for something, flick back, and it flies into your hand. It's very satisfying and intuitive, and possibly my favorite aspect of the design of that game.

I'm not sure if this would translate well out of a game design and into "real world" mixed reality, but it's an interesting thought.

vatys··on Intel plans spinoff of FPGA unit
I see them used in pro/prosumer audio equipment, synthesizers, and effects, which is relatively low volume and medium-to-high budget. FPGAs (and CPLDs, µC+AFE, etc) are great for these applications because they have great capabilities you might otherwise need a pile of discrete components or a custom chip for, but it doesn’t make sense to design fully custom silicon if you’re only ever going to sell about 50-500 of something.

So sure, prototyping and military, but there are other uses as well. But none of them are super high-volume because once you’re selling millions of something you should be designing your own chips.

vatys··on Island gigantism
Perhaps the tardigrades spilled on the moon by the lander crash will become giants
vatys··on Nebula Genomics – First to offer consumer anonymous sequencing
Yes, I definitely considered that as well. Basically, I knew that 23andme data would eventually exist outside 23andme, whether that be via hack, acquisition, or eminent domain.

I accepted that and did it anyway, taking steps to at least not be directly associated with my sequence, even if my association can be inferred or derived later. My main concern is that their testing would identify something which in the future would be a "pre-existing condition" and get me denied medical care, but there is certainly a long list of other possible consequences.

At this point I don't trust any company or agency that collects and uses data, or the promises made in any privacy policy, but I also don't lose any sleep over it.

vatys··on Nebula Genomics – First to offer consumer anonymous sequencing
When I signed up for 23andme many years ago, it was via a friend in another country, who re-mailed it for me under a fake name and paid in cash. For some time I would log in through a locale-specific 23andme sub-domain until they eventually merged it all together.

It wasn't long before they figured out who I was and placed me within my family tree. My fake name now lives among near and distant relatives I was not aware had signed up themselves or their parents/grandparents. They know who I am, who my siblings and cousins and aunts and uncles are, etc. This was always going to happen as soon as I sent them my sample.

I never believed my anonymity trick would truly work, I just wanted to make it sufficiently difficult for when 23andme inevitably sold out, got gobbled up, or turned evil. I learned what I wanted from the service, and have only logged in once a year or so since to see if they updated any findings or disease studies.

While I truly appreciate the concept of bringing privacy and anonymity to this field, it's worth considering we are all quite easy to identify using these samples.

vatys··on Earth’s innermost layer is a 644 kilometer wide ball of iron, new study finds
If we started mining the earth’s core, it would seem infinite at first. Can we be trusted to only take a little bit and not eventually hollow it out?
vatys··on I Broke into a Bank Account with an AI-Generated Voice
> 30 year old movie

It may be a shock but that movie will actually turn 41 this summer.

It seems the author has shown that a replicant can trick a bank.

One step away from downloading more RAM
vatys··on All Circuits are Busy Now: The 1990 AT&T Long Distance Network Collapse (1995)
> The Bell System standard was an extremely high Erlang number

I wasn't aware of erlang the unit (measuring telephone circuit load) and at first thought this had something to do with the language.

vatys··on Omg.lol – A lovable web page and email address
Thank you for reminding me that SDF still exists. I just logged into my account there for the first time since 2005, and it still works.
vatys··on Galactic settlement of low-mass stars as a resolution to the Fermi paradox
Perhaps our electromagnetic communication would seem as advanced as cave paintings, and we have no means to identify more advanced communication.
vatys··on Tracker Beeper
Before I played the video and heard the sound it made, my first thought was that it would make a haunting clicking sound like a Geiger counter. Sure, it would be annoying, but I think it would be somewhat fitting.
vatys··on Repurposing an old Android phone as a web server
Yes, commonly referred to as a “battery emulator” in EE labs for mobile devices. Some are lab grade test equipment from big name vendors, and some are home-grown concoctions which use a power supply, capacitors, and adjustable load to shunt the power when the device tries to “charge” the battery. If a battery charging circuit is running, it’s generally not enough to just provide a DC power supply, it actually needs to be able to both source and sink current. But if the battery charger can be disabled, then a high current power supply, lots of capacitors, and a good short connection can be enough to replace a battery for a phone/tablet.
vatys··on Ask HN: Is there a TV on the market without “Smart TV” features?
That sounds like a smart TV, or at least what one should be. Like an actually well made, non buggy, secure smart TV.
vatys··on Case Studies in USB-C Debugging (2020)
The worst thing about having read the USB PD specification is having to live with this knowledge
vatys··on The hunt for the M1’s neural engine
That's what I'm saying, in response to the previous comment saying this is to work around a bug. Bugs are common to all parts, where defects are unique per part. Binning works around manufacturing defects and turns a yield problem into different grades or SKUs of parts.
vatys··on The hunt for the M1’s neural engine
For chips, that's commonly referred to as "binning" as in the sorting machine drops chips into different bins based on a test result.

A big design with many cores, such as CPU or GPU cores, may have manufacturing defects that makes one or more cores bad. Or it may be on one side or another of a tolerance range and not be able to work at higher power or higher frequency. These parts may get "binned" into a lower performance category, with some cores disabled (because a flaw prevents the core from working) or with reduced maximum performance states.

These are still "good" parts, and can be sold at a lower cost with lower performance, while the "better" and "best" parts will pass more tests and be able to have more or all portions of the chip enabled.

So it's not so much to work around a "bug" which might be a common flaw to all part designs, rather to work around manufacturing tolerance and allow more built parts to be useful rather than garbage.

How does one know which category they are in?
vatys··on Peeling away the myth about how the Golden Gate Bridge is painted
I feel like I have a fuzzy early 80s childhood memory of a gray Golden Gate Bridge but I can’t be sure or prove it. Maybe it’s like a Bernstein Bears thing, where I have the same wrong memory as other people.
vatys··on USB Type-C finally shows up in power tools
You might be better off getting a fixed power profile from the brick and regulating down to your desired voltage separately. While it's possible the brick will be well regulated, it's likely to have some noise and output voltage variability. Even for a hobbyist, the DC supply should be clean and well regulated, or you might be stuck debugging your hobby design only to realize it was a power issue all along.

A small board/box with a DC to DC regulator, knob, and display, could still be quite a bit smaller than a big bench supply, and provide reasonable performance. USB-C in (at a fixed power profile) to an output from a variable buck supply, for example.
