paxswill··on ESP32-C3 Wireless Adventure: A Comprehensive Guide to IoT [pdf]
The Adafruit Feather boards usually have built-in LiPo support.
paxswill··on Hyundai and Kia settle lawsuit worth $200M over vehicle theft due to TikTok
Because their cars lacked an immobilizer, which most other manufacturers have included as standard for a long time (and Kia and Hyundai only stopped using them recently). Some countries require them in new cars as well.

paxswill··on More than you cared to know about PC fans
Those fans that start at 30% and then allow you to go lower are explicitly allowed by the spec from Intel (linked in the article, sec 3.2 and 3.4).
paxswill··on FDA moves to make over-the-counter hearing aids available
High frequency hearing loss is associated with decreased intelligibility, and some of the harder situations to discern people is in a group or noisy environment.

I had a fairly rapid decrease in my high frequency hearing (basically my ears aged 20 years in a few months), and the biggest indicator to me was how much harder it was to understand dialogue in loud shows. I was turning on subtitles and/or turning the volume up where before I was fine with a fairly quiet volume.

paxswill··on IPTV Pirate Must Pay £963K or 88 Month Prison Sentence Becomes 168 Months
Many states in the US allow private citizens to start prosecutions that then get passed to a public prosecutor; some also allow private citizens to attempt to convince a magistrate to issue arrest warrants. There are also a few that allow private citizens to try a complete case (ex: Virginia). It’s rare, and not allowed for federal cases, but is a thing in the US.
paxswill··on When Apple Built a Mac OS Running on Top of Solaris and HP-UX
> There was a time when Apple has email mailing lists. Here is the MAE User list. And Apple published the archives for people to search. I tell ya. Was a different time at Apple.

Apple still has a handful of mailing lists (they’re mostly dead though): https://lists.apple.com/mailman/listinfo

Unfortunately many of the archives are restricted to members.

paxswill··on Single binary executable packages
Rust links glibc dynamically, and can use musl for some platforms. By default most (all?) of the musl targets are linked statically, but they should be able to use dynamic linking for it as well.
paxswill··on SixtyFPS Becomes Slint
Integrating accessibility into the tutorial is fantastic, but I’d also attribute it to Apple emphasizing accessibility in their developer documentation for a long time. I remember one of the early Interface Builder tutorials explaining accessibility pretty early on.
paxswill··on Ask HN: Do you know any computer language where collections are unified?
Core Foundation (Apple’s C library) sort of uses this with its “array” type: https://ridiculousfish.com/blog/posts/array.html
paxswill··on Hello IPv6: a minimal tutorial for IPv4 users
Depending on your DHCP and DNS servers, they might already have this built in. dnsmasq will maintain DNS entries for the DHCP leases it hands out, and can also add AAAA records if it sees a SLAAC message for a MAC address it gave a DHCP lease to. BIND’s servers (dhcpd, named, kea) can be set up so that for each DHCP lease assigned, a DDNS update is sent.
paxswill··on State of netbooting Raspberry Pi in 2021
The easiest way to perform the flash is by booting into Raspbian and performing the process interactively. Without this one-time process, you can't netboot, as the default setting is the SD card, then USB: https://www.raspberrypi.org/documentation/computers/raspberr...
paxswill··on State of netbooting Raspberry Pi in 2021
From my own experience, they're probably flashing the RPi4's EEPROM with an updated bootloader and config to enable netboot. Here's the official documentation on it: https://www.raspberrypi.org/documentation/computers/raspberr...
paxswill··on Bring back hydrogen lifting gas
Echoing a sibling comment, that thread goes down the conspiracy rabbit hole very quickly. A few inaccuracies I noticed before giving up:

* "Remember, only 13 deaths out of the 36 passengers on the airship died." This skips the crew deaths (who also died at about the same rate).

* There were a bunch of photographers present at Lakehurst as it was the first crossing of 1937. The audio recording was not scripted, the original disc records a pressure wave which is followed by Morrison exclaiming that the Hindenburg is on fire.

* "Mary Jane" can be a real person's name.

* "Hugo Eckener, former head of the Zeppelin Company, Charles Rosendahl, commander of the Naval Air Station at Lakehurst, Max Pruss, captain of the Hindenburg and most of the surviving crew believed the airship had been sabotaged.". Eckener stated that it could be sabotage when he was first told the Hindenburg had gone down. He later backed the static spark theory.

paxswill··on PC can't be shipped to CA, CO, HI, OR, VT or WA due to power consumption

paxswill··on Debian Bullseye Fully Frozen
Probably this one: https://db.debian.org/fetchkey.cgi?fingerprint=58B66D48736BE...

Debian uses PGP signing pretty extensively, and maintain a keyserver (and separate search interface I used for this) for their keys: https://keyring.debian.org/

paxswill··on Halide for iPad
I feel the issue in this case is more a tablet being used to record a show versus a phone. The larger tablet blocks more of the view of people behind you. This does kind of fall apart with the blurred distinction between large phones and small tablets though, so in this case I feel like their decision was the right way to go (in addition to the other issues like false positives, complexity, etc).
paxswill··on My Favorite One Liners
Not a one-liner by itself, but sticking pbcopy/pbpaste into a pipeline is great for quick text processing. Wish you had regency support in a text field? `pbpaste | sed s/needle/NEEDLE/g | pbcopy`
paxswill··on DIY Camera Using Raspberry Pi
I briefly used Kerberos.io a few years ago (kind of a difficult name SEO-wise), and it seemed to work pretty well.
paxswill··on FTP is 50 years old
The place I see it most is in networking RFCs.
paxswill··on How many Devices can you Connect to the I2C Bus?
Ugh, I've been using a datasheet from Panasonic [0] recently, and it's been a trip. The original Japanese is all there, with a lackluster English translation below each paragraph. Plugging the Japanese in to Google Translate for the particularly bad sections usually helps. At least this version is clean, I ran across a few PDFs floating around for this part that looked like they had been run though the print-scan-jpeg cycle a few times.

paxswill··on SolidRun 1U 2 node Arm Server
You can get the board for $750, but it says 8 weeks shipping: https://shop.solid-run.com/product/SRLX216S00D00GE064H08CH/

It's mini-ITX, so there's a pile of cases you can use for it if you want.

paxswill··on Debian Packages That Need Lovin'
Like this? https://www.debian.org/doc/debian-policy/ap-flowcharts.html

I skimmed the New Maintainers Guide for a rough idea of what to do and then used the Debian Policy Manual with the various debhelper manpages for specific references of what each field/script meant. I also dig into the source of some packages to see how they were packaged (for example, when I was creating an archive keyring). The two areas I had the most trouble with were deb triggers and debconf, which only seem to be documented on external sites.

paxswill··on OpenStreetMap charts a controversial new direction
If you're referring to maps produced by the US government, they are in the public domain. Early on it sounds like there wasn't an easy way to transfer "raw" map data around (hence the tracing), but it's pretty easy now to access official maps in full resolution:

* US Geological Survey: https://www.usgs.gov/core-science-systems/ngp/tnm-delivery

* National Park Service: https://mapservices.nps.gov/arcgis/rest/services

* US Forest Service: https://www.fs.usda.gov/visit/maps (the API access is further down that page).

Those linked above typically available through a standard API (Tile Map Service), as well as ESRI's moderately well documented REST API for accessing shapefiles and features. My one complaint about this data is how the USFS manages their data. In that case it seems each service region defines how data should be made available, so you have a pile of different methods for accessing things like road/trail features, or points of interest (in many cases, it comes down to "fetch this pile of ZIP files").

paxswill··on Behold z, the unsung jewel that rethinks shell navigation
In my experience, CDPATH is a great way to lose hours chasing down errors throughout your scripts.
paxswill··on A Trip into FreeBSD
A sibling comment mentions mDNS, which can work but sometimes requires an extra package.

The simpler solution is to connect your DHCP and DNS servers. Dnsmasq has this built in, and is frankly a fantastic piece of software. If you’re sticking with ISC servers, BIND can be configure to allow dynamic DNS updates, and dhcpd can in turn be configured to manage those updates.

paxswill··on FPGA NTP Server
I was surprised to find PTP on my network a while back: Airplay 2 uses it in some cases.
paxswill··on Half Doses of Moderna Vaccine Produce Neutralizing Antibodies
(Summarizing things I've picked up from reading Derek Lowe's blog [0])

Not all antibodies are neutralizing. Antibodies can only bind to a certain part of pathogens, but if an antibody binds to something it might not disrupt what that thing needs to do to infect the body. Relating this to SARS-CoV-2, it looks like if an antibody bind to something other than the spike protein, the virus can still infect cells. As another example, most people have been exposed to at least some other coronaviruses, and of that group, some of those people have developed antibodies that react to SARS-CoV-2. A recent paper [1] looked at if these "cross-reactive" antibodies were helpful in preventing COVID, but it looks like they're non-neutralizing as they couldn't see any effect.

paxswill··on Siliconpr0n: High Resolution Chip Maps
AA sibling comment mentions double tap to zoom in on a paragraph, but there's also a single finger zoom (tap and hold, then move the held finger vertically) for Maps (and by default in MapBoxGL last I checked).
paxswill··on I bought 200 Raspberry Pi Model B’s and I’m going to fix them
Time Machine just runs over SMB now (older versions used AFP). There’s some extra options you have to set in Samba to get it working, but it’s not that much. Setting up mDNS properly will also make it show up in the UI like a Time Capsule as well. Synology and TrueNAS (née FreeNAS) also support it (it took me all of 2 minutes to set up in FreeNAS a while back).
