retzkek··on ICE Deports 3 U.S. Citizen Children Held Incommunicado Prior to the Deportation
And then, what? Are citizens beating down the doors to do these jobs but getting out-competed by migrants? Are these the same citizens who are lining up to do sweatshop labor when manufacturing “returns” to the US?

If undocumented workers are finding productive work in an economy with low unemployment then the problem is that the government is not facilitating them gaining legal status.

Update: the former 18F folks have stood up a new site: https://18f.org/guides/
retzkek··on GSA Eliminates 18F
Their web dev guides - especially for a11y - are high quality, and were taken offline this morning. I stood up a copy (slightly modified) at https://guides.18f.kmr.me/

Hopefully the GitHub repos stick around; I forked and cloned a few and suggest folks browse through them and grab anything that looks interesting in case they disappear.

There are many conspiracy theories related to his trip to Moscow in 1987, which I don’t ascribe much to, but the connections are there, if only for some “assistance” to be rendered quid pro quo.

I’m a firm believer in Hanlon’s Razor, and like you ascribe most of his and his followers’ actions to stupidity, but there’s clearly also some maliciousness.

retzkek··on Fidget
Years ago in college I did a bit of work on a nuclear physics simulator (think: reactor modeling) that based its geometrical model on implicit surfaces, specifically R-functions (of which min(x,y) is an example), which have some neat properties such as being differentiable everywhere. This is a good introduction (and probably the only one in English): https://ecommons.cornell.edu/items/35ae0f68-1af5-4f28-8b8b-7...

I've been away from the nuclear field for a while, but I imagine it's still using a lot of legacy Fortran codes to do modeling. Fidget has some interesting possibilities as a kernel for a new simulation package.

retzkek··on Advent of Code on the Nintendo DS
I struggled with APL last year. This year I’ve been enjoying trying to solve the problems in uiua (“wee-wha”). It’s a symbol-based array language like APL, with a wonderful online editor and code formatter (also command line), that formats on each run, and lets you type in English keywords that it converts into symbols, so you don’t have to hunt and peck through the virtual keyboard or remember a bunch of arbitrary chords.

There’s a decent VSCode plugin but I mostly use the online pad because it’s such a rich environment. Very active Discord, with an AoC channel for help and sharing solutions - the maintainer actively iterates on the language to help them solve AoC problems.

https://www.uiua.org/

(I also fall back to Clojure when I’m struggling to come up with a uiua solution or banging my head against the stack, I kinda wish I had uiua-in-Clojure like how April is APL-in-CL)

> Not on topic, but from the other side of the Atlantic, how on earth did the US go from "her emails/lock her up" being a rallying cry to electing the guy who stacked piles of classified documents in his bathroom?

The same way football (any kind) fans boo every call against their team and cheer every call that goes in their teams' favor. American politics has been almost completely turned into a sport.

retzkek··on Chinese pebble-bed nuclear reactor passes "meltdown" test
There is a similar unit used for tracking nuclear fuel “burnup,” which is how much energy it produced: GWd/t (or GWd/MTU).
retzkek··on Thinking about recipe formats more than anyone should
mise in place is the art of reducing all that other stuff to as close as zero time as possible during the cooking, and many recipes expect the cook to read through first and identify what can be prepared/placed in advance. https://en.wikipedia.org/wiki/Mise_en_place

retzkek··on Where the Digital Sidewalk Ends
I refer to Strava and RideWithGPS heatmaps whenever planning a new cycling or running route, and they are very useful, but they still need vetting (satellite and street view mostly) since 1) people have different tolerances for safe/comfortable interactions with traffic, and 2) road race data is often mixed in (despite users being able to tag races), which frequently are on (closed) roads you wouldn’t want to be on otherwise.

retzkek··on The Architecture of London Pubs (1966)
A random blog I found through Kagi Small Web is one man's journey to visit all the pubs in the Good Beer Guide: https://simeyeveritt.wixsite.com/brapa

It's such an interesting look into these slices of life, both current and former, that are so unlike my own experiences.

retzkek··on Sndkit – a toolkit for computer music composition
> Brackets and s-expressions can be fun, but they can get very unwieldy very quickly in LIL, especially since backslashes are required to break up commands across different lines.

> The previous vibrato example

    sine [add [param 440] [sine 6 50]] 0.5
> can be rewritten without brackets using a special function called 'zz':

    sine 6 50
    add zz 440
    sine zz 0.5
> zz itself doesn't do anything. It is a placeholder that tells the function to use the argument that has been implicitely generated.

This is an interesting approach to making stacked operations more readable, similar to the "thread-as" macro in Clojure [1], which would make the example look like:

    (as-> (sine 6 50) zz
          (add zz 440)
          (sine zz 0.5))
Of course, with this example in Clojure one could use "thread-first":

    (-> (sine 6 50)
        (add 440)
        (sine 0.5))

retzkek··on Boeing workers vote to strike
I didn't sense any judgement there, just a statement of fact. Learning a new language as an adult is doable, but not trivial, so it's certainly a factor in making a decision to relocate to another country for a job.
retzkek··on The Minneapolis Street Grid: Explained
> Not sure about west. :)

Unincorporated addresses in Kane and DuPage Counties do use a reference system based off State & Madison as baseline (although it's been codified based off county and township lines). Eg. 40W100 Keslinger Rd is a bit over 40 miles west of State St.

retzkek··on Oracle will use three nuclear reactors to power 1-gigawatt AI data center
Amusingly that’s not a nuclear plant pictured; looks like coal. I don’t think we’re going to see a general nuclear renaissance in the US, but it has its part to play. Co-locating with a massive data center can make a lot of sense.
retzkek··on How to build a 50k ton forging press
That's pretty ungenerous. The press release says "The press is the world’s strongest hydraulic pull-down die forging press in pit-mounted design" so it's easy for a layman to read "world's strongest ... press" and take that at face value.
retzkek··on In ‘The Book Against Death,’ Elias Canetti rants against mortality
> Moreover, while longer lifespans may drive calcification, they would also promote long-term thinking. How would we vote about the climate differently if we knew we'd be around for a couple hundred years?

Would we act more in favor of the general long-term good, or would we scramble even more to get ours now in order to secure our own future? I'm not so sure cooperation would win.

retzkek··on In ‘The Book Against Death,’ Elias Canetti rants against mortality
What if you could ask an octopus the same, and it suggested that dying after breeding is best for society to prevent the problems of overpopulation [1]? Unlike your hypothetical aliens, octopodes live in the same resource-constrained world we do.

retzkek··on Ask HN: What are the best books you've ever read?
The Overstory by Richard Powers - an intertwining of lives, as witnessed by the oldest beings on Earth, putting things into a rather different perspective.

The Windup Girl by Paolo Bacigalupi - compassion and redemption, set in a terrifyingly plausible near future where the oil and tech companies have been replaced by gene and agro conglomerates. Calories or joules, it’s just energy.

Weaveworld by Clive Barker - a dark, fantastical yarn of vivid (sometimes grotesque) imagery, spinning a new take on the oldest tale, that of good vs. evil.

retzkek··on Dumb website only lets one user in at a time
Seems to be documented, surprisingly: https://<INSTANCE>.service-now.com/cancel_my_transaction.do

https://support.servicenow.com/kb?id=kb_article_view&sysparm...

Or you can type “cancel_my_transaction.do” in the navigator filter bar. Related tip: you can quickly bring up any table by typing “table_name.list” (s/.do/.list/ from the single-item url) there instead of poking around for a link. “sys_user.list” is probably the one I use most often.

retzkek··on Report on the role of standardized test scores in undergraduate admissions [pdf]
The NY Times article about this addressed that concern specifically, indeed it was the key point of the study:

> It’s worth acknowledging a crucial part of this story. Dartmouth admits disadvantaged students who have scores that are lower on average than those of privileged students. The college doesn’t apologize for that. Students from poor neighborhoods or troubled high schools have effectively been running with wind in their face. They are not competing fairly with affluent teenagers.

> I also asked whether she was worried that conservative critics of affirmative action might use test scores to accuse Dartmouth of violating the recent Supreme Court ruling barring race-conscious admissions. She was not. Dartmouth can legally admit a diverse class while using test scores as one part of its holistic admissions process, she said.

retzkek··on What is wrong with TOML? (2019)
Maybe you'd like jsonnet: https://jsonnet.org/

I find it particularly useful for configurations that often have repeated boilerplate, like ansible playbooks or deploying a bunch of "similar-but" services to kubernetes (with https://tanka.dev).

Dhall is also quite interesting, with some tradeoffs: https://dhall-lang.org/

A few years ago I did a small comparison by re-implementing one of my simpler ansible playbooks: https://github.com/retzkek/ansible-dhall-jsonnet

retzkek··on Effect of Breakfast Skipping and Late Night Eating on BMI with Type 2 Diabetes
As usual, it's from people pushing their beliefs and/or their products on the public to serve their own purposes; further, as with so many modern ills, we can put some of the blame on Edward Bernays.

retzkek··on What's wrong with enterprise Linux
Absolutely. RHEL 7 (and downstreams) has maintenance support for another year, so there are many systems that administrators and now looking at upgrading. Speculatively, Red Hat timed the source availability change strategically to coincide with this epoch and force these administrators into a tight spot and hopefully get more subscriptions.

Should these systems have been upgraded sooner? One year has usually allowed plenty of time for testing and rollout of the next major release.

retzkek··on The force that shapes everything around us: Parking
I assume you mean for crossing busy roads and highways, not city streets? Certainly there are places for that, like Chicago's Lake Shore Drive. They're expensive and take a lot of space themselves, though, especially to meet accessibility requirements, and they can add considerable distance to the pedestrian's route.

Otherwise, what you're describing sounds like someone looked at this well-circulated cartoon and said "hey that's a great idea! Just raise the planks by 15 feet!" https://www.vox.com/xpress/2014/11/18/7236471/cars-pedestria...
