Hello, I am one of the engineers on Docker Hub. If the image was ever pushed via a tag which must be the case if it was done via docker CLI then that image is never deleted (unless the tag is deleted from Hub UI and no other tag refer to it). This means if sha256:c34ce3c1fcc0c7431e1392cc3abd0dfe2192ffea1898d5250f199d3ac8d8720f was referred by latest tag which was pushed to another image sometime later then `FROM tomcat@sha256:c34ce3c1fcc0c7431e1392cc3abd0dfe2192ffea1898d5250f199d3ac8d8720f` will continue to work. Apologies for not having this documented. I'll work on getting this documented on https://docs.docker.com/docker-hub/.

The Frank Lloyd Wright Foundation just released a collaboration with an art gallery, Spoke Art (SF), called Timeless, a collection of WPA-style posters by local and international artists. I went to the exhibit when it was at Taliesin West a few weeks ago and ended up buying 2 of the posters to hang in my room. There are 2 more exhibits in the future, one at Taliesin East and one in Spoke Art's sister gallery in NYC. Here is the first of 3 collections for anyone interested: https://spoke-art.com/collections/frank-lloyd-wright-timeles...
This isn't reinventing Unix, this is a (cut down part of) Unix. (Unix the family, not the original Bell Labs OS, of course).

And "non-portable" because it's only portable to Unix? That's... Approximately everything. Linux family and Darwin naively, NT via WSL/cygwin/etc., BSDs obviously, Android sorta-natively or via Termux, Chrome OS via Termux, crouton, or crostani(sp?). What is Unix not portable to?

Does osx not have the fuser command? It lets you find and kill a process by its tcp port (also file handles) in one command.

On Linux I use something like 'fuser -k 19421/tcp' to kill server processes all the time. It is super useful when working with local dev servers etc!
So how is this different than standard oil again? Not that I'm advocating breaking up the tech companies but it's no coincidence that the growth of the modern conglomerate has also strongly correlated with income disparity. Instead of 5 CEOs and 25 VPs, you now have 1 CEO, 5 VPs, and 25 Junior VPs all being paid less because they no longer get the same share of the equity.

That's not true. These days even the smallest US banks tend to have mobile apps or normal mobile banking options. All the major banks without exception do. That has been true for years at this point.

Deposits, moving money in various ways, checking balances or statements, bill pay, customer service, etc etc. What exactly is missing that is important that American banking desperately lacks? The larger banks are borderline obnoxious with the options ('features') they try push on you, for what their mobile banking offers now.

The only thing I can think of, is easy & instant account funds transfer from one person's bank account to another person's bank account (which is a structural flaw in the US system, and which PayPal & Co. fill).
Even after all that, there's always the analog hole which can never be fixed.
If you do end up with telomeres that shorten very slowly, could there also be pressure to shorten them more quickly, so it really is just a measurement? Hypothesis: telomerase, which fights the shortening, also promotes cancer. I think I've even seen that before.

"Some experiments have raised questions on whether telomerase can be used as an anti-aging therapy, namely, the fact that mice with elevated levels of telomerase have higher cancer incidence and hence do not live longer. Telomerase also favors tumorogenesis, which leads to questions about its potential as an anti-aging therapy.[36] On the other hand, one study showed that activating telomerase in cancer-resistant mice by overexpressing its catalytic subunit extended lifespan.[37]

A study that focused on Ashkenazi Jews found that long-lived subjects inherited a hyperactive version of telomerase.[38] " https://en.wikipedia.org/wiki/Telomerase

x87 has been functionally superseded (largely by various SSE iterations), but it is still supported for backwards-compatibility.

Modern applications and compilers largely do not use x87, but they can, and x87 results depending on hidden bits persists in modern x86_64 CPUs.
This is exactly the wrong design pattern to follow. Translation from code to business model has always been problematic. Reducing that translation by modeling code after a business domain (not a business object) is the best way to reduce complexity and enable a longer life for a system.

Would you say “I’m using Chrome and Visual Studio” or “I’m using a Windows workflow and tools” or “I’m using explorer.exe” ?

The first two make much more sense to me than the third.

(As an aside, it’s not true that Bash is “the Unix shell” and it is in fact not the default on several Unix-like systems. But in fairness to your point, it is the default on most GNU/Linux distros).
I wish I could figure out. My best guesses are:

1. I am getting older and not doing anything remotely impactful.
2. People half my age know all the programming I know. I don't bring anything special to the table.
3. Is this what life is all about?

Now, I don't say the problem is with the world. Something could be wrong with me. But damned if I know.
Maybe. As far as anyone can determine, some physical processes (e.g. radioactive decay) really are random. There is "noise" in reality. Even with a perfect accounting of every subatomic particle in the universe, you couldn't predict when a particular atom will decay.
The calculations are actually really easy. Note that the length of a (regular) year is 1 mod 7, which means weekdays slip by 1 day each year, except for leap years. Over the 400-year Gregorian calendar cycle, there are 97 leap years, for a total of 497 days of slip... so adding 400 years to the current calendar year will always yield the same calendar.

More specifically, there are 14 possible calendars. The leap year cycle is 4 days (excluding the 100 year skips), and the weekday cycle is 7 days, so the leap year×weekday cycle is 28 years. So the starting weekdays are on a 28-year cycle, but you have to slip your resulting calculation by the number of centuries from the beginning of the 400-year cycle (i.e., integer division of year by 100). You'll reuse a leap year calendar in 28 years (40 years, if it crosses a round-hundred year), and you'll reuse a non-leap year calendar in 6 or 11 years (12 or 6 years, if it cross a round-hundred year).

The easiest way to code it is to just precompute the year % 400 table and report the results.

This may be good for numerical simulation, but I doubt this will ever replace common ieee754 float in general purpose programs. Two problems I can see right away:

- Sometimes, one needs precision for numbers not close to 1. A UNIX timestamp is a good example -- for the current date, it provides ~1uS resolution in 64-bit ieee754. I could not calculate what the resolution would be for posits, but I suspect much worse.

- The lack of positive and negative infinites will break naive min/max calculations which start accumulator with +/-inf.

Now, you might say that those things should not be done, and that software that uses those patters is defective. But even then, there is a lot of software like this, and so posits will never become a default "float" type.
The recommendation engine works the other way - it can happily expose people to content that makes them a worse person.
Yes, and India too. Every little roadside vendor now accepts Paytm or PhonePe or Google Pay or Mobikwik or Freecharge. The only way to get money into these mobile wallets is either by linking to a bank account, linking to a credit card, or by doing a wallet-to-wallet transfer.

But what surprises me is the extent of penetration of these wallets despite not being cash based. To a large extent, this success is probably attributable to the "glue" between these disparate wallets - the government-launched UPI or Unified Payments Interface (https://www.npci.org.in/product-overview/upi-product-overvie...), which allows you to link any of these wallets directly to your bank account.

Okay, you shamed me into doing it :)

So, this is really rough napkin math, but here goes:

Assuming that...

... a sedentary person (Donald) has a resting BPM of 80.

... an active runner (Justin) has a resting BPM of 60, and a peak BPM of 180 (while running)

If Justin runs for a solid 2 hours, five times a week, he will have

158*60*60 + 10*60*180 = 676,800 beats per week

While Donald, who doesn't run, but averages 1 hour a week doing strenuous activity, will have

167*60*80 + 1*60*180 = 812,400 beats per week

Donald's heart beats 20% more often than Justin's. (And that's assuming Donald's heart also peaks at 180.)

I don't have the source code of this site, but checking if a calendar can be used again is pretty easy.

1. Check which weekday the year starts

2. Check if this year is a leap year.

If the year starts on the same weekday as another year and the leap-yeariness is the same, the year is the same.

With this info it's really easy to use your favorite date library to check which years match, but you can also do that manually.

Each year starts on the next weekday that the previous year did. (2019-01-01 was a Tuesday, 2020-01-01 will be a Wednesday) except when that previous year was a leap year. In that case one day is skipped.

It's true, and the microscopic theory was done by the same physicist who found the macroscopic relationship, Geoffrey West (one of my personal heroes an current director of the Santa Fe Institute). The theory also explains the upper and lower bounds for the possible size of an animal. If you want to read about it he wrote an amazing book called Scale. I _highly_ recommend it.

Are you serious about the PDF viewers? Windows has Sumatra, Xodo, Drawboard all of which are fine and the first two are free.

Mac OS on the other hand, has had a broken pdfkit implementation since around Sierra, and any PDF viewer that relies on it (Preview, Skim) has broken and blurry rendering of which there are several reports online. This makes any PDF reader other than Adobe's (which is an abomination) unusable. This has gone mostly unnoticed or ignored as the blur is reduced by the high PPI screens, although it is there and becomes much more apparent on a lower PPI external screen.

This single fact makes Mac OS unusable for me. Windows has its own faults, but at least I can read crisp PDFs on it.
All of the big things on here I already knew were owned by Amazon (Zappos, IMDB, etc.)...all of the small things were trivial clothing imprints or similar. This is a pretty substanceless piece.
Look, there is always going to be stuff that is banned from Youtube. They're not going to allow porn on there. Given that they control content to some extent, the question has to be what their responsibility is.

Also, recommendations aren't part of a platform, they are Youtube's free speech. Those are in some ways more important than mere hosting, as that's how Youtube has radicalized people.
And, out of curiosity, what would you say if someone made an argument that company X, while not owned by the government, is effectively a monopoly due in significant part to government intervention? Mechanisms for this might be: patent grants, regulations that create significant barriers to entry for new competitors, lucrative contracts with a federal department, inconsistent enforcement of existing laws while the incumbent has protective connections with the enforcers, tariffs...
From what I understand, Standard Oil used their dominance in the market to stifle competition and 'restrain trade'. Because Amazon is big doesn't necessarily mean they are doing these things. I would imagine they are being very careful not to fall foul of these laws, unlike Microsoft in 2001.
You can actually increase your telomeres?

When should you leave your job?
I've been working at my current job for 2.4 years. I feel very comfortable in it....and that makes me uncomfortable. I'm not being challenged. The rate that I'm learning new things (technical and non-technical) is decreasing.

I'm hesitant to jump ship before I can find something better, but I don't know what company I'd like to work for. Should I quit first to focus on finding a new job? Or keep at it until something comes up?

It's not misleading at all. It could have been 512 of the same character. It's not about how it can be stored more efficiently, it's just to visually demonstrate 512 bytes, which requires 512 characters (in straight ASCII anyway).

perhaps you could preprocess the shape using the Binary Space Partitioning (BSP) algorithm. there’s a step in the algorithm that finds polygons that would cause z-sorting conflict and splits them along the exact line you need to resolve the conflict. you end up with a data structure that gives you the z sorting order for any camera angle.
OK, I'll add a bit to my previous comment. Is there a limit to how small a mammal can be? If so, what sets the scale?

TL;DR – effective pumping of blood requires precise allowable branching network of capillaries in the circulatory system. At a certain size this network goes from AC to DC and sets the scale for metabolic rate and lifespan in all animals with a circulatory system.

The scale is set by impendance matching of the circulatory system. The heart pumps blood. It is AC. To prevent the AC wave of blood from reflecting back when the capillaries branch out and get smaller, the branching network of the capillaries requires the cross-sectional area of the mother branch to be equal to the sum of the cross-sectional areas of the daughter branches. But when capillaries get too small the heart loses this AC advantage and goes from AC blood wave to purely DC.

So the smallest mammal a shrew has 2 capillary branches, 1 AC, 1 DC. Humans have 8 branches 6 AC then 2 like the shrew 1AC, 1 DC. A blue whale has 15 branches 7 AC then 8 like a human (6 AC then 2 like the shrew 1AC, 1 DC). This branching network sets the smallest length scale of a mammal (actually for any animal that uses blood and mitochondria as its metabolic energy source).

Going back, a shrew has 2 branches 1AC, 1DC. A shrew is 4cm in length and its heart must beat 20 times a second, as nearly all the hearts energy for all animals is expended to push blood through the last small DC branch portion of the capillaries. The shrew must be only 4cm and pump blood with the same pressure and speed as a human (which is the same speed and pressure as a blue whale) through the shrew’s tiny little heart. That is, smaller the animal the larger the metabolic rate. The larger the metabolic rate, the more wear and tear and repair on cells, the shorter the life span.
It is no longer great (it used to be so around Mavericks). Current pdfkit is broken, and renders PDFs blurry, with the effect enhanced on low PPI screens. This holds for iOS as well since the same pdfkit is used, but since the devices running those are extremely high PPI this bug goes unnoticed by all but those looking for it or those with sensitivity to such imperfections. I think the state of PDF rendering on macOS right now is unnacceptable.

Reasons I'm interested, stability and transaction fees. You don't want to pay someone in a deflationary currency, as their salary will always increase. A stable coin solves this in allowing people to actually use it.

The lower fees enable micro transactions which is something that I believe the internet needs in order to move away from ads. I'd happily pay a fraction of a cent per page view, there is no good way to do that right now.

Reminds me of a career limiting move I made at my first job. I was a rising star and got head hunted to be the first member on a new team for a critical project. I took the opportunity because it had a higher potential for career growth, but I ended up leaving the company.

I considered my manager an egotistical jerk; he even called our 1:1s lessons. He told me that any part of my personality that didn’t line up with what the company would score on a Meyers Briggs was a problem. A senior engineer decided he was my mentor but constantly put me down. My team dangled the promise of a promotion if I could the job at my level and fulfill the job description of an open headcount two levels above me. I worked overnight every Tuesday sleeping only 4 hrs on my couch. I was miserable and in the end they said I couldn’t be promoted because the work I had was already stressing me out too much (I gave notice between reviews being finalized and revealed to make it clear this wasn’t a tantrum over my review)

My takeaway: it doesn’t matter what the maximum possible achievement is in a job; you’ll only rise if you can enjoy it. Successful people aren’t happy; happy people are successful.
I have nothing to do with this thread, but felt like answering anyway...

1. Very few people leave a legacy. The people that do often didn't do it deliberately or intentionally.

2. They don't. There might be a few people half your age that know as much about programming as you do, but the majority don't. In any case, you are the worst person to judge what special thing you bring to the table. Go and ask one of these young people that you fear / respect / admire / think are knowledgeable and ask them to tell you what value you bring. The answer will surprise you.

3. A lot of people have pondered the meaning of life. Opinions differ on whether we've made any progress on that question. It's OK to go on a journey of "spiritual discovery" at 37; it doesn't require heading overseas to a monastery.

> The reason this news registered among scientists is that methane is often a sign of life; although the gas can be produced by various chemical reactions, most of it comes from animate beings.

This doesn't sound right at all. There are literally lakes of methane on Titan. The atmospheres of Jupiter, Saturn, Uranus, and Neptune all contain significant methane--it's what makes Uranus and Neptune blue. Pluto has methane ice.

IIRC from the original reporting, some recent research suggested that there's more methane than contemporary geological models of Mars predict. Which likely says more about the [non-biological] deficiencies in those models than it does the likelihood of life.

I'm not an astro-anything, so feel free to correct me. But it's telling that the interviewee never comes close to confirming the reporter's claims; they're simply quoted as saying, "I think probably many people would like the idea of methanogens on Mars", and "the idea that they might be related to methanogens on Earth is not crazy." Isaac Chotiner is a name I'll try to remember so I can avoid his articles.

For triangles only the intersection case matters. General Polygons could be a bit more complicated. As long as the object is watertight, it's easier.

I recently ran into similar problems to be solved in Python, because I am trying to build a replacement for OpenSCAD by duct-taping together various Python packages. Shapely is quite useful for 2D geometry (like intersection and stuff). PyMesh is extremely useful for 3D meshes, but hard to build.

There are some non photorealistic rendering (NPR) options for Blender, many of them implemented in Python. I don't know if they can output SVG data currently.

ThreeJs has an SVG engine, meaning a backend that outputs SVG.
