TJSomething··on Atlassian moving to cloud-only, will stop selling server licenses
Dang. I actually like how customizable Jira's workflows are. What else is good at customizable Scrum-like workflows with custom fields?
TJSomething··on We now consider Moment.js to be a legacy project in maintenance mode
The article specifically states that they're going to keep Moment-Timezone up to date. Which is important, because the timezone database has changed approximately 4 times a year for the last 5 years (https://mm.icann.org/pipermail/tz-announce/).
TJSomething··on How Big Oil Misled the Public into Believing Plastic Would Be Recycled
From a global warming perspective, plastic bags are generally better for the environment because they are extremely light, therefore use less gas to ship. However, plastic bags often end up in nature, where plastic particles end up in animals and plants.
TJSomething··on Fixing Mass Effect black blobs on modern AMD CPUs
While true, there is a reason that the GLSL standard includes builtin data types for matnxm for all n,m in {2, 3, 4}. The single most common matrix operations in computer graphics are related to linear transforms on color spaces and geometry. Both of those max out at transforms on 4D vectors, for RGBA and 3D projective geometry.
TJSomething··on Show HN: SheetUI – Turn Google Sheets into Web Pages
I think a Gopherhole is to the Gopher protocol as a website is to HTTP.
TJSomething··on GPT-3 Creative Fiction
I like providing some context that prompts the model for a list if I think I might need a few candidates. "We discovered a series of journals by several authors in the cabin. The authors' names were:" worked pretty well.
TJSomething··on The World Doesn’t Need a New Gigantic Particle Collider
All non-random decisions are made against models of the world. Some of those models are more detailed than others. All detailed models are made by people who care a lot and have interests at stake. It's not possible to make decisions outside the context of a narrative.
TJSomething··on Nginx UI – Access and modify the Nginx configurations files without CLI
"State of the art" doesn't really indicate age. It just means that there's nothing better. I'd be interested in learning about anything that's better than containers.
TJSomething··on Biohacking Lite
They aren't saints, but McDonald's has several different salads and they're pretty healthy if you don't use dressing.
TJSomething··on Blur Tools for Signal
The resolutions on those are way higher than what Signal is doing. It's not surprising that a neural network can give a decent guess at what a face can look like. Faces don't have that much entropy. But you can blur them out if you get it down to like 4x4 pixels.

Anyway, if you want scarier panopticon stuff, you should look into gait recognition, which is way harder to censor.

TJSomething··on Deconfinement: The Price of Human Life
The primary risk factors of economic recessions take years. Most cancers take years to kill people. The effect of unemployment on suicide peaks at around 2.5 years of unemployment [0]. I think that we're going to have an economic downturn with repercussions that will last long after a SARS-CoV-2 vaccine exists. I also think the ends currently justify the means, but that's just a gut feeling I've got.

[0] Milner, Allison et al. “Long-term unemployment and suicide: a systematic review and meta-analysis.” PloS one vol. 8,1 (2013): e51333. doi:10.1371/journal.pone.0051333

TJSomething··on Janet: a lightweight, expressive and modern Lisp
Zulu and Corretto are both distributions of OpenJDK.
TJSomething··on Ask HN: What scientific phenomenon do you wish someone would explain better?
Additionally, many problems are can be converted to matrix operations, like graph algorithms.

Note that matrix multiplication takes O(n^2) time with a quantum computer, but O(n^2.807) time on a classical computer.

TJSomething··on U.S. Government official: Coronavirus vaccine trial starts Monday
Where did you get that number? The United Nations thinks that we're going to hit 8 billion by around 2023 and 9 billion by about 2037 [0].

TJSomething··on Spelunky Level Generator Lessons (2013)
As a few other people and the page noted, it only works in Chrome. For Firefox, it fails when it tries to use chrome.storage. That doesn't even work in Chrome, as it's an API that can only be accessed by extensions. However, in Chrome, the chrome object is defined, so accessing chrome.storage just returns undefined instead of throwing.

It's kind of weird that it's using that when it could just use localStorage.

TJSomething··on How Popular Is “Sign in with Apple”?
It's mostly compliant as of a few months ago [0]. That document is actually out of date, because Apple added a discovery endpoint since then [1]. They also haven't implemented the userinfo endpoint, but the only claims they expose are openid, name, and email, so it's not that big of a deal to just ask for those in the id_token. And the client_secret_post thing isn't much of a problem either, since their custom JWT is a perfectly valid client secret that's compliant with the underlying OAuth 2.0 standard and it's explained in their discovery document.

TJSomething··on Boeing has temporarily stopped making 737 Max airplanes
But Windows 7 was just Windows Vista with some relatively minor changes and it was fine.

The problem with the 737 MAX is that Boeing tried to make a plane with a completely different airframe and added a bunch of software to try to make it fly exactly like second generation 737s so that pilots didn't need to retrain. But the abstraction was leaky and it turns out that when you have a different airframe, you have to retrain your pilots.

That said, Boeing did some janky stuff to get this nonsense certified by the FAA and the whole design probably needs to be recertified, which will take years.

TJSomething··on Adult site leaks data of cam models
It took me a couple reads, but do you mean "shell" (as in a shell company that does nothing but exist to protect or obscure the operations of another company) instead of "shill" (a person who markets for someone while hiding that they are associated with them)?
TJSomething··on Reality has a surprising amount of detail (2017)
Isn't working alone part of being self-taught?

My school tried to teach good habits. Many of the professors are out of touch with what good habits are though, so they usually teach to books of varying quality or practices specific to how they learned a few decades ago.

TJSomething··on The most important scientific problems have yet to be solved (1897)
It's not really a random walk in any way. Having designed artificial evolutionary systems, even if you screw up the implementation and the search space is really bumpy, it usually still makes progress, albeit very slowly.
TJSomething··on Now using Zstandard instead of xz for package compression
It's not 0.8 times size increase, it's a 0.008 times size increase, since the unit is percent. The latter seems pretty marginal to me.
TJSomething··on U.S. government limits exports of artificial intelligence software
My reading is that it's the GUI used to train a neural network to identify any objects in geospatial imagery. I'm definitely less okay with that. Although, I feel like the GUI is not the hard part to make, so it's a weird part to restrict.
TJSomething··on IncludeOS: a minimal unikernel operating system for C++ services
I'm skeptical that you couldn't get similar reductions in carbon footprint through investing the money you gain by delivering early on renewable energy infrastructure and carbon sequestering charities. Of course, how that cost-benefit analysis works out depends entirely on required engineering hours and the growth of your business, which are both notoriously difficult to predict.

That said, if your goal is reducing expenditures, reducing your carbon footprint is a great cherry on top.

TJSomething··on Google is not a search engine, but an ad engine
I suspect that advertising and selling marketing data are the only ways to make search profitable.
TJSomething··on A Personal API
It takes me 26 flicks of my scroll wheel to show a single column. Given the content, each column should be about 3 flicks max.
TJSomething··on PIA VPN to be acquired by malware company founded by former Israeli spy
I mean, there's actually an active lawsuit against Altria for securities fraud Altria lying about JUUL to their investors. Similar lawsuits are common. Being a public company gives people with lots of money and lawyers (i.e. investors) motivation to make sure that the company's core value proposition isn't a big fat lie.

I don't think that alone is sufficient evidence to immediately completely trust Kape, but it's worth some points in my book. And if the lawyers don't pull out any dirty laundry after a while, I'm going to assume there isn't any.

TJSomething··on Rooms can be as bright as the outdoors
The most cited paper on this is "Stability, Precision, and Near-24-Hour Period of the Human Circadian Pacemaker" (Czeisler, et al., 1999), which found that their 24 subjects between ages 13 and 65 had a mean circadian rhythm of 24 hours 10 minutes with a standard deviation of 8 minutes. Earlier studies were affected by artificial light lengthening cycles. Non-24 sleep-wake disorder in sighted people is not researched well enough to have accurate rates: there are only about a hundred cases in the existing studies and the disorder is not well known and probably underdiagnosed.
TJSomething··on Ask HN: What should be taught in high school?
Even though it's not the best SQL database, Access is a really good force multiplier if you're in a locked down office and all you have is Office.
TJSomething··on Ask HN: What's the most valuable thing you can learn in an hour?
Transformation by substitution is part of most dialects of regex, in the form of capturing groups.
TJSomething··on By removing “extremist content,” platforms are purging human rights evidence
This policy was actually changed in 2017 to completely ignore robots.txt.
