I'd call the reaction notation pseudocode inasmuch as I'd call assembly language pseudocode or prime factorizations pseudocode -- they're equivalent in completely mechanical way. (Caveat: there needs to be a prime<->species assignment block, too.)

A way I'd been experimenting with FRACTRAN is with a slightly different notation, Python:

B = 2
A = 3
M2 = 5
Div = 7
M1 = 11
Count = 13

prog = [
(M1 * A, M2 * B**10),
(M1, M2 * A),
(M2 * A * Div, M1 * B),
(M2 * B**4 * Div, M1 * A),
(M2, Count),
(B, A),
(A**2, Div),
(Div, M1)
]

It uses multiplicative rather than additive notation. All that's left is to take the RHS and divide it by the LHS.

On HN a while back, someone posted something about how Petri nets are the same as rewrite rules in a commutative monoid, and seeing as FRACTRAN is sort of a system of rewrite rules, I thought to see whether anyone had made the connection before, and sure enough there's a paper. Cook, Soloveichik, Winfree, and Bruck, "Programmability of chemical reaction networks." http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.155...
It looks like webrecorder has a downloadable version you can run entirely on local storage with no need for an account.
I'd rather read about someone's experience with the tool mentioned. If they prefer something else, I hope they share that and why. The graphviz thing in particular feels like someone who has an interest in the future of graphviz hijacks any alternative to say that graphviz exists.
Over the last year there's been a significant amount of low level changes in the proprietary versions of spark (aka EMR and Databricks) designed to address reliability and stability. Out of curiosity what exceptions did you run into?
The RTOS world is much less of an 'operating system' and more so a bare-bones task scheduler. It's not like a POSIX environment at all.
It doesn't run Android apps (well ... yet!), native apps are "meh", the UI quality is questionable and the battery life miserable. That's my last state of knowledge. Does anybody know how the power management stuff is going? I'm planning to build a mobile device with the very related SOPINE and think that project might profit from some lessons on that front.

And oh yeah, I'm totally planning to buy a PinePhone because because it's cool as hell.
I'm on a 500mbps connection and an overpowered PC and it doesn't feel all that snappy compared to the other examples given here. Each navigation takes >1s, multiple skeleton loaders. Good enough, but far from what we should be seeing with current tech.
The Saturn always struck me as overdesigned and underengineered. So many custom chips to program and coordinate and a high unit cost when the simpler and more flexible approach taken by Sony ends up being just as good and cheaper almost all of the time.
My test results didn't share what platform was used.

I was puzzled finding a good linux board for cheap device. Decent linux is like 10$ price minimum and you probably need something better. It could easily sky rocket to 30$ and this is out of budged of almost any devices. 30$ makes your device retail cost ~100$ already.

While you can get M4 for under a 1$ having all built in and very power efficient.

Also no need to hustle with linux deployment and update rollouts.
Thanks so much for that, very helpful!
I guess my error in thought is that tech would be more of a meritocracy than other disciplines. I'm totally aware I have shortcomings. But you're right, some are better at playing the game than others for various reasons. I don't mean to be argumentative, just frustrated. Just like at the casino, if the deck is indeed stacked against me the best move is to not play.
Also substantially more expensive, especially compared to the likes of the banana pi zero, which gets you four cores at 1.2Ghz, 512MB RAM, Linux and a GPU for 35% cheaper. Pair that with a Blue Pill STM32 for $3 if you need realtime and you still have money left over.
Interesting! I wrote https://plainoldrecipe.com (open source!) to solve this, an inadvertently discovered many of the metadata tags described here.

The strong case for building client-first web apps
The Sega CD2 was actually vastly better, in my recollection. I explicitly got that one and attached it to my full size genesis back in the day.
The Sega Saturn was the first console I purchased with my own money.

The Saturn had some great games.

Three of the Four launch titles were great: Daytona (Rolling Start....), Virtua Fighter, and Panzer Dragon were far better than anything else available.

Street Fighter Alpha 2 was far superior on the Saturn compared to the PS version.

And Guardian Heroes (available now on Xbox Live Arcade) is probably one of the best, most underrated sprite based beat-em-ups.

Ultimately Sony crushed the competition with titles like, Resident Evil 2, Tekken 3, FFVII, Twisted Metal, etc etc. Which is crazy considering how strong the N64 was.

It's sad that Sega laid an egg, but the Saturn had it's time and place.

I'm really looking forward to what the Series X can do with it's project X-cloud. My feeling is that it's going to move towards PC gaming--once your console can no longer play games natively, it will switch to pixel streaming.
Thanks, it helps. I'm actively looking for project ideas.
"$25,000-per-month lease with WeWork for 1,800 square feet"

That is absolutely absurd. $25,000 for an amount of space equivalent to a large 2 bedroom apartment? If this is what kind of rates restaurants are paying for rent, I can imagine why their margins are razor thin.
This is stale discussion already, but going by that logic, why would you sacrifice the majority mom and pop (average person who also lives paycheck to paycheck) for the minority poor? For example right now in NYC, most people find it really hard to buy their first home (not everyone is SWE in FAANG). It isn't like they have spare money to buy bigger toys. Once they worked hard for that why take that away?

I'm not saying not help the poor. We should treat our most vulnerable people, but economically I think it doesn't work out. The poor will always be there, the sick will always be there, the unemployed will always be there no matter what. Even if you help them, they will always be there.
I have been wondering why it is considered to have originated in Wuhan rather than Wuhan simply being the first major outbreak where it was identified as a novel coronavirus. Is it always the case that hospitals will be capable of identifying a new type of virus based on some patients who look like they have the flu?

One thing that's known about covid-19 is that it has an unusual spread pattern. In some circumstances it might not spread too much (eg. average R0 is well less than 10) but in other circumstances where air is recirculating a lot or a particular patient is very contagious, it seems to spread a lot more. Couple that with many people being asymptomatic. So, what if it had been spreading in many places but Wuhan was simply the first place where it was detected? It seems to be capable of spreading without being detected for quite a while in many other parts of the world. (eg. Singapore's foreign worker dormitories)

The Raspberry Pi Zero W is great for tasks that need wifi too (window blinds, etc). At $10 it's cheap and it's really nice to write your programs in python. I've got plenty of experience with microcontrollers and C++ but I find python just so much nicer to use when I can. You can even host a web page from it for a quick and easy GUI control (use Flask for a pure python implementation).

Anecdote-wise, everybody in my home town who owned a playstation had pirated games.

It's always good advice to start with the conceptually simplest tech you can get away with.
And there's far less meaningful innovation in gaming today. VR was pretty promising, but has failed to be transformative. The new consoles' graphics frankly don't look much better than current ones IMHO, despite having 10x or 100x the performance. Game streaming is the most interesting and disruptive technology, once the major players figure out the right business model.

Back in the 90s, opening a gaming magazine was so exciting due to the crazy stuff you might glimpse.
I think you're making a massive mistake comparing 'the US' and China for a whole number of reasons. Firstly, The US has 246 deaths per million people, New York has 1381 deaths per million, California has 69 deaths per million people. So if we're actually staying on topic of the California plant, actually California is an example of the US doing relatively well. And the reason they're doing well is because of their stringent lock down rules. In fact California probably is doing better than China did in reality - because China's deaths per million is stated as 58 and that's clearly a number no one really beleives.

Secondly you need to think about the fact that Musk is going ballistic about the US being a totalitarian state- and we're meant to be looking at China as the comparison? Really? I'd love to see a Chinese CEO make statements about the Chinese government like Musk makes about the US.

Finally, the government isn't even saying that Tesla shouldn't reopen the plant, they're just working on making sure they're doing it safely. And you should be listening to the government about this, because it's been pretty conclusively demonstrated by Musk that he can't be trusted on this topic.
Working through their docs recently my first thought was: huh, I was under the impression that it would do more for me.

But then I realised that it actually does do a lot for me, but they really managed to package it all up in a relatively (and deceptively) simple API that so far still does not seem leaky at all.
MERS and SARS are not a huge concern (they never achieved wide circulation), but coronaviruses make up ~40% of what we know as the common cold.

That said, if the false positive rate were that high, the specificity of the test would be low.
Sounds cheaper than paying a freelancer $0.025 per word, too.

I suppose if you were just starting a blogspam recipe site, you could initially pay freelancers for the first articles, and use them as your training corpus. But since this sort of templated recipe site is already evil, just scrape all the other recipe sites and use their articles as your corpus.

"When we vacationed in { madlib( international_city ) }, we ate a { r.Name }, and it was delicious. When we returned home, we tried to recreate the recipe, but it was never quite right. After months of trying, it's finally perfect."

"As a child, I remember my grandmother making { r.Name } and eating it with all my cousins. It was her secret recipe. She never told anyone. When she died, we were all very sad because we thought the recipe was gone forever. But I found this in her old { madlib( noun ) }, and now I'm the most popular cousin at the reunion."

Repeat ad nauseam.
Great article and also I think this is very country specific. In the UK this is already happening, many people who work in London commute from Slough and Reading. House prices in Reading been increasing for quite a while https://www.zoopla.co.uk/house-prices/reading/

> how Rust and Hack are changing the face of programming

It's in there.
Thanks. Yes I think those are great questions that the model (shell-shell contact momentum transfer) can address. All aspects of the existing mathematical description can be built into the shell-contact model but will require serious updates to our animation skills. That being said, I hope we can accomplish those details later. Magnetism, light, and gravity are next on the list, however.

Resistance is inability to conduct; so orbitals are not charged (with a CW or CCW cohesion) on balance. Electricity acting on these non-polarized surfaces leads to heat.

Capacitance has to do with the induction of voltage during separation by an insulator.

Electron spinning is a bit of a simplification; the real concept is angular momentum. In reality it is impossible to deconvolve the contribution of speed and trajectory from momentum. Ideally instead of fast rotating shells as charged, we should animate cohesive motion as well as speed, but that is beyond our present abilities.

RF will come with videos on light later.

Thank you for the comments! Stay tuned.
The people who do invest in the market are providing the money that drives jobs and economic growth.

You can't separate the two.
I agree with your generalization. Here's another:

Companies will completely disregard this information and will base the amount of office space and WFH policies based on the cost of real estate post COVID19.

I predict that when the virus situation calms down, companies will tend to prefer WFH policies until some companies start noticing how cheap office leases are. At that point, we'll ramp back up to where we are today for the same bogus reasons we have open office plans and lots of butts in seats.

I also predict that there will be a bubble of architecture changes for new housing builds: single family homes (that often have a home office space) will start to be built with 2 home offices to support married couples both working from home.

it depends. in the next 10 years, no.
next 100 years, probably no.

I'm not sure why this would be worth doing for the employer. once you add up salary and associated costs (health insurance, payroll, etc.), a typical engineer costs at least $100,000/yr in most areas of the US. if a few of them abuse the system to buy $1000 graphics cards, does it really move the needle?

my employer does not reimburse home office expenses, but several of my friends work for employers that do. the way it works for them is that they get a yearly "technology" budget of about $1000-2000. then they can spend it on any equipment they want to use at home or in the office. as long as it's some sort of computer hardware or office furniture, no questions are asked.

> Don't think anyone with radical views has ever been convinced by someone explaining - calmly or otherwise - why they're wrong.

Well, I can disprove that: me. I grew up with some pretty homophobic views, and due to some very patient people in my life, I realized I was wrong. And I've had similar conversations with other people and seen their views change over time.

> As to the OP's question of whether he's obligated to talk to his father, with whom he shares no interests and disagrees on strongly-held beliefs, multiple times per week. My answer would be a hard no, but that's far from cutting him out of his life.

I don't think there's any obligation.

> I agree with you that it's emotionally beneficial to have a connection with your parents where possible, and that OP could try to have contact with his dad. But forcing it on a very regular basis when it's unpleasant and uncomfortable seems counter-productive.

There's a range of unpleasantness and discomfort, and I think some level of both is a necessary part of growth. If every conversation turns into a screaming match--sure that's counterproductive. But if you're at a point in your life when you can handle disagreement in a healthy way, disagreement doesn't need to be avoided.
So let’s count the benefits:

No more wasted times commuting

More time spent with family

Men and women equalize pay and home responsibilities

Personal freedom and comfort

Cuts down on the #1 source of fossil fuel pollution

Benefits for employers:

Geographical restrictions lifted

Bigger talent pool

Save on office space, equipment, workers comp insurance

Save on transportation subsidies (parking spots etc.)
That's a lot of vitriol for a tasty vegan snack.
The posted coremark scores do not support your claim that NXP iMXRT1062 is substantially more powerful. If I take these numbers at face value, then STM32 promises up to 45% more perf.
I feel like the “Make website browsable offline” feature of yesteryears have been neglected. Somehow people assume everyone always has internet connectivity... but I need to save websites, docs, etc, for long flights or camping trips without signal.

Safari annoyingly has a reading list feature that claims to cache the web page but annoyingly 50% of the time doesn’t. As with all apple cloud services there is just no way to explicitly sync.
Vernacular English isn't capable of describing some concepts succinctly enough to be useful to mathematicians. If English was superior people would be using it.

Just like organisms evolve things such as vision, frontal lobes, etc, we have evolved aging because it ultimately positively impacts the survival of species. This makes it an evolved feature, wouldn't you say?
There's a big difference between in major cities and near major cities. Certainly, not all that long ago, wealthier people mostly lived in suburbs though that's probably not as generally true today for coastal cities in particular. I tend to know more older people who mostly don't live in urban cores.
Thanks for the feedback! We're preparing a demo for the upcoming Spark Summit next month... Stay tuned :)

In the meantime you can book a time with one of our data engineers through the website to get a live demo: https://www.datamechanics.co
it is impossible to deconvolve speed/direction in terms of momentum of the electron, so we simplified the idea with rotation speed. Ideally, the high charge atoms would be more cohesive as well as faster.

Can you disambiguate that further? I think you mean that an ETL tool would handle the external interface work whereas Nifi is dealing with data that is somewhat inside your control. Is that an OK description?

Three books that dive into the problems of our "local control" system, including how it can be anti-democratic:

Neighborhood Defenders by Katherine Einstein et al

Segregation By Design by Jessica Trounstine (recently won a planning book of the year award)

And though it's not about loca control, as much, The Color of Law by Richard Rothstein is an essential for looking at the federal policies that forced segregation in housing.
If students can trust themselves to build skills and develop universities are objectively a bad deal in the US right now. Get admitted, make one payment and drop out kids.
Yup. Sold our house in January using Redfin. Best realtor we've dealt with and saved 2%.

Also watch out for realtors saying you need upgrades and recommending contractors. They likely are getting a kickback, and by boosting the listing price their commission goes up. You end up with the same proceeds, IF it sells as fast, and you had to front the upgrades.

The incentive structure for realtors is whack. At a minimum, the commissions could be tiered instead of continuous.
That demo is a ray marching shader with hardly any geometry, and the geometry is procedural. You do understand this method can't be used to render video games or films?

> RTX looks like a gimmick with the sole purpose of enforcing vendor lock-in.

That's like saying a floating point unit, or a Google TPU, or even an Intel CPU is a gimmick to enforce vendor lock-in. If you want to do something faster in software, you can make hardware for it. Don't buy hardware if you don't need speed.
Your header says "plan old recipe"
> I think you can list ingredients of a recipe with no problem, but once you get to exact measurements and prep it somehow switches over to falling under copyright law.

In the US, recipes are not protected by copyright, including precise measurements and instructions for how to combine them.

If you write sufficiently creative instructions those may be protected by copyright, but I can get around that by simply not replicating those instructions. I can give exactly the same list of ingredients and a less-creative set of instructions for the same dish without infringing your copyright.

Copyright.gov has a circular which explains this with a couple examples [1].

I guess this is a good opportunity for a pinephone related project self-promotion. :)

A few days ago I've published my custom bootloader for PinePhone: https://megous.com/git/p-boot/about/

It's the one I use for a quick booting to Linux: https://www.youtube.com/watch?v=kxqdF7H_It8

Something to try if you have a pinephone and want to experience sub-second boot times.

Anyway, if you like bringing up new hardware, or optimizing things, this is as good an opportunity as it gets to get pinephone and have fun. There are lots and lots of areas that can be optimized and improved in usersapce and in the kernel and you can do whatever you fancy or want to learn about. It's all being developed by random people on the internet. ;)
The employer might not but the IRS might if you claim it as a home office expense. If more people work from home and beef up their home offices to accommodate that, there will be tax implications for that. When I was freelancing from home years ago, I never bothered (all I needed for work was email and a red pencil), but today it would be different.
Holy shit, that just hit home hard... I just pitched doing multi-armed bandits for ad placement.
