"half life of CO2 in the atmosphere" is a bit misleading, (most|some) people will think it means the quantity of CO2 in the atmosphere halves every 30 years. That is false.

This NASA link says CO2 stays in the atmosphere for hundreds of years: https://climate.nasa.gov/news/2915/the-atmosphere-getting-a-...

And this site: https://www.skepticalscience.com/co2-residence-time.htm

explains that while the individual molecule CO2 hangs around the atmosphere for 3-4 years, it's then merely exchanged with one in the oceans (or maybe one in a rotting tree).

On this study: https://scholars.unh.edu/cgi/viewcontent.cgi?referer=https:/...

on page 4 (shown 25 on the page), you can see the box model of the global carbon cycle. Halflife refers on how long the a CO2 molecule spends in a given box.
To do that you would have to identify a "pdf - the accessible parts" of the spec, or perhaps "pdf - possible accessible layouts" and the implementer would have to stick to that. This might come into conflict with government regulations regarding how particular pdfs should be laid out - that is to say if there was a layout that would break natural screen reading flow it would be inaccessible and thus not allowed by Law 2, but be required by Law 1.

This becomes difficult when writing Law 2 because probably you don't know all variations that can be required by Law 1 (where Law 1 is actually a long list of laws and regulations)

Depending on the legal system of a particular country writing Law 2 might not be actually feasible unless you know what Law 1 entails.

Just from experience, I'm not sure I'd trust a military-style assessment to accurately identify skills. For example, I scored off the charts on linguistic comprehension (the Defense Language Aptitude Battery DLAB) and had a job as far from that as you can imagine.

It might be worth considering who "they" are (from your insanely outraging "why can't they lay bricks?" akin to "let them eat cake"). And why wouldn't "they" sweat for a good wage? Seriously, do some soul searching.

I don't understand why most of the things discussed in the article continue to be the responsibility of web page authors. For print media of course it makes sense for publishers to hire typesetters to agonise over font size. But for online content, please just send me the text itself and let _me_ choose how to most comfortably read it! Doing anything else is pretty obnoxious.
I agree there is merit in the idea of encoding instruction dependencies in the ISA. There have been a number of research projects in this area, e.g. wavescalar, EDGE/TRIPS, etc.

It's not only about reducing the need for figuring out dependencies at runtime, but you could also partly reduce the need for the (power hungry and hard to scale!) register file to communicate between instructions.

On the one hand, this is bad news - I would prefer ARM to remain independent. But on the other, from a purely selfish standpoint, NVIDIA will likely lean on Apple pretty hard to get its GPUs into Apple devices again, which bodes well for GPGPU and deep learning applications.

Apple is probably putting together a RISC-V hardware group as we speak. The Jobs ethos will not allow them to depend this heavily on somebody else for such a critical technology.
I can imagine solemnly written tweets with typos going unnoticed by the author for hours or days, if ever noticed. This is especially frustrating once a tweet has gained traction, because deleting and reposting means you lose all the engagement of the original post.

It reminds me of Larry David’s Beloved Aunt incident. Larry paid for an obit in the newspaper to say that the deceased person was a, “devoted sister, beloved aunt”. There was a typo in the word “aunt”... Anyways, the newspaper was printed and distributed and there was no feasible way for the message to be corrected. It seems strange that that same limitation is, arguably, unnecessarily and arbitrarily enforced on a digital platform.

Python had keywords that were supposed to make methods and fields private or read only or something like that. I remember they were gone by 1.4; I never liked or used them.

I’ve been in a “retro computing” deep dive lately and it’s been fascinating to discover Forth. I was surprised that an entirely novel paradigm was hidden despite much digging over many years. All of the sudden I am seeing it everywhere now too - confirmation bias from growing up skill wise in the age of dot com boom vs right before?

I like the feeling of concatenative languages. I especially seem to like the postfix notation over prefix and largely this creates the paradigm of lisp vs forth at first step - in my opinion.

I’ve recently dug in to Factor and it’s quite an amazing piece of art that is highly usable and up to date despite such a small community. It almost feels like a secret weapon and too good to be true. I’m having a ton of fun hacking on it. It’s like Smalltalk and forth had a baby.

I dream of making an OS with Forth/Factor similar to Plan9 and Oberon.

I get a kick out of Forth being made of words and Genesis from the Bible.

At first was the Word, and the Word was with Forth, and the Word was Forth.

https://factorcode.org/

https://en.wikipedia.org/wiki/Oberon_(operating_system)

Tidbit if anyone cares: I’ve been obsessing over returning to first principles of computing. I’m bored of the internet and browsers. I want to have fun with software AND hardware and Forth seems like such a perfect language to do exactly that with. Factor is a nice grown up example of that but it’s definitely a few steps removed from portability and self bootstrapping behavior like in CollapseOS.

Retro Forth is extremely impressive: http://forth.works

True that join is nice. I was just not sure if real-time join is truly necessary for Uber’s use cases, or AresDB is so much better than a query engine like Presto to justify its effort. Or more fundamentally, is GPU the solution to expensive joins?
-Earth's atmosphere is at present heavily oxidizing and so phosphine is not common here. Phosphine will always be oxidized to phosphate (which is everywhere on earth and much of it abiotic).

You can make phosphine from entirely abiotic common elements and salts literally hundreds of ways. It's almost exactly like saying how many abiotic syntheses of water (OH2) are there (all combustions for starters...)

Actually it was really The Human Use of Human Beings published two years after Cybernetics which was wildly popular, Wiener having rewritten his argument for a 'general audience' - sans all that calculus.

How well read was Wiener actually though? The historian Ronald Kline compares these books to the status of Steven Hawkins' Brief History of Time upon its release. The books anyone invested in intellectual development needed /to show/ they had a copy of, rather than one they exactly made it through cover to cover.
>There also doesn't appear to be any indisputable evidence that officially dates the Great Pyramids and the Sphinx to the purported time period of around 2,500 BC, the age of Khufu.

The fact that there isn't any Predynastic pottery at the Great Pyramids severely limits any kind speculation as to when they were built, at least in the backward direction.
Far from a conspiracy theory, Larry Ellison has been very vocal in his support of Trump (and a major donor!), and Safra Catz actually served on the Trump transition team.
Yes but we have independent observation of that baryonic matter. Suppose we hadn't discovered the theory of relativity. The rules for gravity hold everywhere except for the orbit of Mercury. For several decades it is reasonable to guess there is "mystery meat" planet somewhere that we can't see. Possibly even a hamburger sized black hole orbiting the sun. But to think that the field equations for gravity are wrong is nonsense. Fast forward a few decades and Eventually we can't find this mystery planet and it's decided that an interpretation that the gravity field equations are wrong is more sensible.

Depends on your definition of hellish. I guess Venus could be called that but it is not comparable to the pressures and temperatures that are found inside gas giants. For example Jupiter is estimated at 24000 Celsius at the core with pressures of several million bar. This is vastly different than environment on Venus and that is why they have no credible abiotic explanation for phosphine generation on Venus.

My point was that Venus is not comparable to a gas giant.
Perhaps this is linked to the China and US trade war?

Maybe US customs have been instructed to be harsher on Chinese company imports?

Not saying it is necessarily unethical considering that China is no doubt doing similar.

Anthropomorphic climate change is a function of population and CO2 emissions per capita.

With earth's population projected to increase by 50% over today's number of 7.5 billion by 2100, and economic growth a central tenet of all major economies, it's difficult to see that temperature gradient being arrested.

By 2100, the world’s population is projected to reach approximately 10.9 billion

But in the context of office vs home, if the OP is basically saying "I like my free commute" then you have to remove cost & time from the "pro" list for WFH.

I used to like reading on the train as time for myself but it didn't balance out the other stress & cost of commuting.

If Transport for London said that trains would be free at the point of use & actually put on enough service that most people got a seat I'd definitely consider the office more favourably again
I guess having the “stick” on it has to do with antenna quality.

https://www.bluflux.com/bluetooth-antenna-design-guide-step-...: “So 31mm is the desired length of a Bluetooth antenna without “dielectric loading” (see next section)”

https://www.instructables.com/id/Increase-and-extend-the-ran...: “As Bluetooth devices work at frequencies of around 2450MHz, the formula will give you an antenna length of +/- 12cm.
This figure then has to be divided by 4 to give us a quarter wave antenna, which will be 30mm in length”

AirPods are 40.5mm (https://en.wikipedia.org/wiki/AirPods), so I guess they have such a 30-ish mm antenna (edit: https://www.ifixit.com/Teardown/AirPods+Teardown/75578 agrees: “That hanging boom is for more than just balance—it's also to improve reception.“)

Chances are hanging the antenna (a tiny bit) away from the bag of water called “skull” also helps reception quality. It also provides an easy handle to take them out of your ears.

Alternative designs come with their own problems or ugliness.

The ones that look like buttons give me the impression that it's a medical device and are simply too pronounced. I assume they are that beefy because they need to house the battery in the "head" but the "head and stick" design can have more elegant head since the battery is in the stick part. Since Apple was the first to have that design, they now pretty much own it.

I also suspect that the microphones work better with the head&stick design since the orientation of the mic and the proximity to the mouth is better.

The original goal of PDF was to create documents that could "view and print anywhere" (literally the original tagline of the Acrobat project), substantially the same as how the document creator intended them. What Adobe was trying to solve was the problem of sending someone a document that looked a particular way and when they rendered it on their printer or display, it looked different, e.g. having a different number of pages because subtle font differences caused word-wrapping to change the number of lines and thus the page flow. It wasn't about it being "pretty," it was about having functional differences due to local rendering and font availability. In this regard, the format is an emphatic success.

I do wish they had focused a bit more on non-visual aspects such as screen-reader data, but to say the whole point is "because it's pretty" is a bit uncharitable. The format doesn't solve the problem you wish it solved, but it does solve a problem other than making things "pretty."
Yes. But. The main problem is that in many cases the visual structure is some highly custom form that is hard to present to the user in text.

And on top of this many times there are no text data in the PDF just a JBIG2 image per page.
