gte525u··on Rent growth is slowing (where housing got built)
bls.gov
gte525u··on The SR-71 Blackbird Astro-Nav System worked by tracking the stars
In space they still use similar methods. A different division of a company I used to work for built star trackers for satellites.
gte525u··on Unix Domain Sockets vs Loopback TCP Sockets (2014)
It's a bit obscure but 127.x.x.x is a /8. So you have quite a few loopback IPs/port combos. I've tested it and it works with Windows, Linux, GHS integrity.
gte525u··on WASM: Big deal or little deal?
This is the killer use-case outside of the web. Embedding untrusted/semi-trusted code into a bigger application or runtime and exposing a specific API to it.
gte525u··on Ask HN: Why did Python win?
Python had significant traction back in the late '90s (~1.4/1.5). It was perl vs python vs TCL (possibly vs Guile) back then.

Cross platform and the ease of integrating to other codebases (both extension and embedding) are two parts. Perl's transition to Perl 6 seemed to hurt/fragment that community more so than python 2000 did to python. TCL seemed to slowly die except for a couple niche applications - possibly expedited by Sun's slow demise. Guile never really ran well on non-*nix systems.

Fundamentally python had more C/pascal flavor than Ruby's smalltalk's flavor. That made it easy to teach/adopt. A couple big name universities moving from scheme to python for intro CS helped too.

gte525u··on Microsoft is bringing Python to Excel
ITAR and other regulatory issues - being the primary. Not all users are on Office 365 GCC High.
gte525u··on Trying to find some life on the Usenet (2020)
At least my journey was more slashdot => digg => reddit. Reddit seemed to really take off when digg self immolated during their redesign.
gte525u··on Got called to a professor’s office after a complaint his SPARC4 was running slow
I had a similar story with a friend in college in the 2000's. He would always hit Ctrl-z'd to "close" emacs when logged into the server which would've been fine if he wasn't using screen or tmux as well. At some point, he was using a ridiculous amount of RAM on the server and the admins suspended his login to force him to come in.
gte525u··on Ask HN: How can I get better at writing production-level Python?
Type annotations, mypy, lots of documentation.

Where python falls down is the flexibility - if you aren't careful it's write only.

gte525u··on British F-35Bs to bring vertical landing abilities to highways
The US trains for this but I'm not sure it's needed domestically. FAA funds local and regional airports - there are plenty of airstrips all over that could accommodate a fighter or a C130.
gte525u··on Gitless: A simple VCS built on top of Git
FWIW - I've worked with both rebase workflows and merge workflows. If you rebase a long lived branch what breaks is /your/ code not the rest of the codebase in a rebase workflow vs the opposite being true with merges.
gte525u··on Archive your Reddit data before it's too late
Can't you just add .json to different urls to get it that way?
gte525u··on Connect to your Raspberry Pi over USB using gadget mode
FWIW - I was able to do this using a pocketbeagle. We even did this for a small run product where Octavo SIP exposed USB Serial and Ethernet via gadget, and then was a host on the USB1 side.
gte525u··on How to Stare at Your Phone Without Losing Your Soul
I started using Chrome plugin RYS that does something similar - where youtube functions but recommendations are removed. It's helped consumption dramatically. I'm kinda wondering if I need to do the same for reddit and hacker news where links/articles would work but the mainpage / subreddit pages wouldn't.
gte525u··on Vietnam records highest ever temperature of 44.1C
He values his privacy - I believe he's an MD. The engineering is just a hobby.
gte525u··on OpenQNX Source (2007)
Is non-commercial license still a thing? I tried to get one a few years ago and they told me to it wasn't available.
gte525u··on ARM Linux executable mysteriously runs on x86_64 (2016)
I recently set this up (on debian) for an embedded linux project. Using this I was able to mount an image within a chroot and manipulate it using the target's system commands and run both the executable and unit tests for the target processor on my PC.

It is pretty amazing productivity-wise.

gte525u··on A corrupt file led to the FAA ground stoppage – also found in backup system
This is the opposite of a blockchain in that there are centralized, trusted authorities (FAA, EASA) distributing this info.
gte525u··on Why did the F-14 Tomcat retire decades before its peers? (2021)
It's old enough the mid-life upgrade (MLU) program is happening for it.
gte525u··on Ask HN: Any good guide which include best practices for library developers?
Josh Bloch did a good google tech talk on general aspects of API design.

gte525u··on Boeing 787s must be rebooted every 51 days to prevent 'misleading data' (2020)
Airworthiness directive indicates 51.

gte525u··on Ask HN: Best book to learn C in 2022?
C the complete reference - it's part tutorial, part reference, part project book. At the end, there is project where it walks you though making a mini-c interpreter. That project is very approachable and to be honest - that alone is worth the price of the book.
gte525u··on Ask HN: Examples of Microkernels?
BSPs were a mix usually Apache or some more permissive license for common dev boards. They had something more limiting for the kernel. I'm kinda surprised I haven't seen a bootleg version of it floating around somewhere online.

They also had pretty liberal hobbyist/non-commercial license which let you learn the toolchain and develop with some of the middleware. That all went away when RIM (blackberry now) bought them.

Re: manuals - QNX Cookbook was also pretty good read. The documentation from that era were published as real books.

gte525u··on Ask HN: Examples of Microkernels?
QNX's docs[1] are some of the easier ones to read. The neutrino kernel briefly had it's source code available.

gte525u··on Bond sell-off worst since 1949, investor sentiment plummets, Bank of America
Rates and price of bonds are inversely related. This move implies the market expects longer periods of higher interest rates (and thus lower growth).
gte525u··on The tooling ecosystem that adds joy to KiCad
I'm definitely curious.

As a software guy who occasionally does a test or automation fixture, I find the workflow of most EDAs a bit strange. It seems to actively discourage reuse.

Everyone seems to have their own stash of footprints and known good circuits.

gte525u··on Ethereum mining is going away, and miners are not happy
the parent comment means something like render based off of homomorphic encryption.
gte525u··on Ask HN: What are modern architecture patterns for desktop applications?
It's not uncommon to split front end and back end logic into modules. I've seen lots of projects where the business logic is even shared between a suite of applications.

But it's very unusual to split it over an RPC/IPC boundary - it's usually just linked in.

Xi had specific design goals of allowing multiple independently developed front ends. There are use-cases for this type of development but it's largely not worth the effort (YAGNI).

The typical application architecture is going to depend on your use-cases. I.e a db app is going structured different from a game or a CAD program.

gte525u··on I accidentally loaned all my money to the US government
Yes. I don't think anyone knows for sure - like 7.12% seemed amazing at the time but we didn't expect an oil shock or a war in europe.

Bear in mind there are some other technicalities with i-bonds. They are all documented on the treasury direct website:

- you have to hold it for a minimum of 12 months

- there are two parts of the bond a fixed rate (currently 0%) which is set for the lifetime of the bond, and the variable rate which is tried to inflation

- if you hold it for less than 5 years when you withdraw there will be a 3mo interest penalty

- you're limited to 10k purchased per SSN, you can get over 10k if you get your tax refund in i-bonds.

gte525u··on I accidentally loaned all my money to the US government
It's not really golden. It' just i-bond inflation rates are high at the moment.

The bond rates are set per 6 month window - but you get it relative to the purchase date. So if you buy before the last possible day before the rate change date you would get 7.12% (annualized) for 6 months then 9.6% (annualized) for 6 months. If you buy after the rate change, you would get 9.6% (annualized) followed by some yet to be determined yield for 6 months.
