https://en.m.wikipedia.org/wiki/Photorespiration

[..]Reducing photorespiration may not result in increased growth rates for plants. Photorespiration may be necessary for the assimilation of nitrate from soil. Thus, a reduction in photorespiration by genetic engineering or because of increasing atmospheric carbon dioxide (due to fossil fuel burning) may not benefit plants as has been proposed.[11] Several physiological processes may be responsible for linking photorespiration and nitrogen assimilation. Photorespiration increases availability of NADH, which is required for the conversion of nitrate to nitrite. Certain nitrite transporters also transport bicarbonate, and elevated CO2 has been shown to suppress nitrite transport into chloroplasts.[12] However, in an agricultural setting, replacing the native photorespiration pathway with an engineered synthetic pathway to metabolize glycolate in the chloroplast resulted in a 40 percent increase in crop growth.[..]

Basically..boiled down, this is what I understand:

1. We exist because of the sun and photosynthesis.
2. We are just one fart’s way to making another fart. Think Methane. Our metabolic processes and how we eat and live and survive is based on this.
3. Photosynthesis is the planet’s most effective bio regulator. Takes sun’s energy and
4. Nature in its wisdom has pulled down decaying matter to trap carbon. And we are drilling to get all that out and sustaining ourselves with these dredged out fossil fuels.
5. As long as we are fossil fuel reliant and keep eating as we do and produce our food using fossil fuels that was meant to stay buried, we are acting to accelerate our extinction.
6. We have to stop relying on fossil fuels. No amount of bio tinkering would do.
7. We should seriously reconsider ‘farming’ as we know it and how we create fuel for our physical selves to stay alive. Maybe we are doing it wrong.

In other words, are we destroying the planet by eating? And by extension, by farming. Not just tillage but everything connected with food..from tractors to supply chains is such a massive carbon foot print. Anything to do with fossil fuel is spending sequestered carbon, no? It’s a super simplified way of thinking, but I feel like it boils down to that. Surely we can survive if we don’t farm and eat and transport and cook ‘food’ aka body fuel..as we do now. This could be our fundamental and basic mistake. What if there was another way to sustain our metabolic processes? But we never tried to develop or evolve it? Or maybe this is our march towards entropy.

That’s where I am now.

The idea is good, but the execution is lacking. I get it's a one-man project so far, and that's going to leave you uncertain about its future unlike Patreon. And while Patreon definitely needs competition, creators also needs assurances before they rely on a service.

I honestly wonder why he did not reach out to a few people, who were passionate about the same thing, to help build this service further. As plenty here have already noticed, the website has some quirks right now that might take months to fix, if ever, considering it is just one person running it.

However, I hope all that will turn around, as he gets more press interest, and others might offer to help. And in a year's time, it has become something people might actually want to rely on. I wish him a lot of luck.

I turned my 2017 MBP in with a bad keyboard and a bad USB-C port. Get it back after 10 days with a new keyboard... they forgot the USB-C port. Another round trip, 10 days later... they replaced the IO board on the wrong side of the laptop, the USB-C port is still bad. Screw it I have 3 other USB-C ports now I'm just living with it, I was without my laptop for a month (during which I used my old 2012 MBP which still works fine). Horrible experience.
Most of Chinese think Yuhuangdadi(玉皇大帝) and Wangmuniangniang(王母娘娘) are husband&wife, they work together to control all the gods(gods are not like western gods, they have 仙 and 神), but there are multiple versions of myths(books) and rumors mentioning them, none of them tells the relationship of them for sure, we can only deduce their relationship from the context. From different versions of sources, they can be: 1. husband&wife, 2. colleagues, 3. sister&brother, 4. mother&son.
After years and years of struggling with alcoholism and AA, I got sober with naltrexone using the "Sinclair Method". I followed the treatment plan for a few weeks and at the end quitting drinking was easy and obvious. That was just over ten years ago and I haven't had a drink or gone to any meetings since.

I'm only one person and I'm fully aware that the plural of anecdote isn't data. However, the experience was so drama, and more importantly self-loathing, free and so effective, that I can't help but feel bitter towards the proponents of AA who insist on it being a monopoly... especially those in positions of power in the criminal justice or public health systems because from my perspective it's a malicious and vindictive stance.

If your laptop is that critical you should have a spare on hand. My advice would be to get that windows laptop now, so you can dip a toe in without the pressure of switching completely.

If it’s a secondary device it also doesn’t need to be as expensive, just good enough to get the basics done. E.g. you’re probably fine with i5, 8gb ram, 256 gb ssd, which in windows land means you can get an ultrabook form factor for around $1000. If you haven’t used windows in a while, get a 2-in-1 touch screen model to get the full difference in experience windows has on offer. It’s interesting to have a machine that can switch from full windowed development environment to ipad and back again with a flip of the lid. (Note that I said interesting, not flawless.)

You're right about the level of political risk. But even when there's a revolution or secession, the successor state is still legally liable for the debt. So investors might still get some of their money back.
Combining these two functions, it is possible to take control of the GC to make sure it runs only when it is acceptable to do so.

I'm conflicted on this. My gut tells me if I'm going to manually take control over the garbage collector I should reconsider my design decisions.

Disclaimer, I don't know the first thing about PyPy or Gambit Research, so probably this is the right approach for them?
I’m doing the second setup mentioned a little bit. I have an iMac at home, and my router has a VPN option that I use to SSH from the iPad.

I open all files remotely off the iMac, so Git and tools are not a problem.

The apps I work on hot reload in Safari in a side window. But the lack of JS debug tools is a problem.

Basically it works fine for writing copy, project planning, code review, JS, Ruby, but not so much for static languages (none of the editors use autocomplete servers).

Keyboard is a problem, but because I use a mechanical keyboard on the Mac I can carry around the Mac keyboard in my bag.

This works great if you have a dedicated machine at home, and want to carry around a tablet for doing tablet things (books, Netflix, reading the web, copywriting, UI sketches and some basic dynamic languages).
Adding on to what acemarke said, with which I agree:

Defining a mapping of your table data elements to virtual DOM elements allows React to update only the rows that changed, automatically (from your perspective), which is much faster than messing with the DOM for all rows. Yes, you can do the diffing yourself, at which point you would have rewritten a lot of React.

You mentioned the button example a few times. A normal button in React shouldn't be any more code than doing it in vanilla JavaScript. All those projects with Button.jsx are doing that because they've decided they want to add behavior to a normal HTML button, and they want it consistent throughout their app.

W.r.t. debugging, I meant just reading code, but yes the tooling is very nice too.
> As such, the solution to reducing emissions might be to set up an environmental "beth din" which certifies whether a product is "environmentally kosher" or not. If an intransigent minority only consumes products that are certified environmentally kosher, the passive majority will fall in line

Further:

A. Organizations being held accountable by external audit will be far more likely to engage in ethical behavior than those with internal audits (internal boards are more subject to bias and likely have less access to expertise).

B. This could reduce 'greenwashing' and other exploitative claims over time.

C. The 'intransigent minority' (being willing to invest in such products) fund the initial growth of products, allowing them to gain economies of scale over time. Prices can then lower, and more consumers are then willing to purchase said products.

Norway, along with most other countries during wartime, had severe food rationing going on. It's not a surprise that cancer rates dropped if people were malnourished and dying younger of... everything else but cancer and cardiocirculatory diseases.
> This is because its impossible to bend light beams in free space.

This isn't strictly true, depending on how you define "free space." In fact, you can bend light at will if you can control gravity. Gravitational lensing is the basis for measuring the mass of distant planets and other such astronomical things. So, all you need to do is curve space-time. Thanks Einstein.
It seems plausible that the complex set of control systems that govern our survival became intimately intertwined with various alkaloids over a few million years, "outsourcing" production of raw building blocks to plants. One example is the way in which sulforaphane from broccoli (via glucosinolate glucoraphanin) reduces symptoms of autism in the presence of myrosinase (present in mustard). [^1]

Specifically, on the topic of addiction: "Ibogaine-treated rodents exhibit attenuated opioid withdrawal symptoms, and diminished self-administration of a variety of drugs of abuse, including opioids, cocaine, nicotine and alcohol. Anecdotal evidence suggests that ibogaine is also anti-addictive in humans." [^2]

Meta-analysis of randomized controlled trials show that a single dose of LSD had a beneficial effect on alcohol misuse (OR, 1.95, 95% CI, p=0.0003). [^3]

As we get better at modelling our own bodies, hopefully we can start to selectively replace or suppress some of our out-dated control systems to reduce suffering and increase efficiency while retaining our survivability.

Naltrexone/nalmefene works with 85% of the population, while 15% do not respond because of genetic disposition.

Of the 85% who do respond, 75% are successful in what they are attempting.

Proponents advise you to take it for the rest of your life. Naltrexone is not costly. This is your decision.
Well, I can't tell you low-hanging fruit that's still out there, because if I knew it, I'd be working on it instead of telling you. :) But I can tell you some low-hanging fruit that I've done!

I'll stick to just one example, this[0] paper of mine was, like... I was astonished this was not already in the literature -- everything in this paper is easy to prove once you think to ask the question -- but as best as I and anyone else could tell, somehow nobody had thought to ask the question despite having asked other extremely similar ones. It's especially astonishing that Jacobsthal's exponentiation was independently rediscovered multiple times, but what I call "super-Jacobsthal exponentiation" seems to have only been considered once before and only briefly as a tool for something else (nobody thought to write down its algebraic laws). So, I wrote it up to make sure it was out there.

(Honestly I'd say a lot of my work has been LHF, I got through grad school while learning hardly any of the heavy machinery one normally does, unfortunately most of it isn't written up yet and so I can't really easily point to it.)

>>and that's going to leave you uncertain about its future unlike Patreon

Given the events of the past month or so, I wouldn't be completely sure about the future of patreon. It's definitely shown the way forward in terms of supporting creators, but the repercussions of their actions seem to be gaining a lot of traction and putting doubt into trusting patreon for people who supported creators via the platform in the past.
Here's a possible answer. Imagine a 2d universe - a piece of paper. Cut that paper into infinitely thin lines, and line them up.

You have converted the 2d paper into a 1d line, but in the process have made the line much longer than the 2d version. (Like the difference between Aleph 0 and Aleph 1.)

I don't see any way to go lower than that though.
It subtly discourages functional programming when a for loop would be faster and more readable.
So how many RPIs are hiding in your closets?

I think I've got 3x RPI1B, 2x RPI2B, 2x RPI3B, 2x RPI3B+.

Amazing little machines!

I do wish RPI4 gets USB-C ports. Well, USB3 would do.

I'd also love to have another board with very low power requirements, even less than RPI zeros. Something between Arduino/ESP8266/ESP32/etc. and RPI zero, but can still run Linux.

Like ARM Cortex M7 or similar. Mash one or two ultra low power M0/M1 (so that main core can be completely switched off for low power while remaining active), advanced DMA/DSP engine (like IMX SDMA (NXP?) or TI PRU), lots of reconfigurable IO (fast GPIO, I2C, I2S, (wide) SPI@80MHz+, ADCs, USB 2.0 device/host, bluetooth, wifi, 100M ethernet MAC etc.).

Oh and some digital display interface would be nice as well, it's not nice to connect displays to SPI or worse, I2C.

1 MB SRAM and maybe 16 kB low power SRAM, shared with M0. 16-128 MB low power DRAM.

You should be able to fine grain power off any and all of the components, even DRAM and SRAM (except for that 16 kB shared between M0 and M7).

Oh, and can I get it tomorrow? ;)
Ask HN: Computer Vision in Android in 2018?
I only see opencv and ml kit but not sure what other libraries exist?

Basically I want to monitor a specific region of the screen, the score screen from another running android game which I want to scrape. Is this possible? TextRecognizer seems perfect but I need to use computer vision to "see the game" as it is played.

For instance, in a 2d platform, it should detect when a jump is detected and game over screen appears.

Thanks a bunch.
Both are different types of "damage".

> Every time I do a search and I don’t find what I’m looking for on DDG I think, “I bet Google would have found it”. However when I’m on Google and I don’t find what I’m looking for I think, “I just didn’t write a good query”. That mental hurdle is hard to get over.

Same here. It doesn't help that 80% of the time I'm having the former issue, I copy the query to Google and the top hit is perfect, a hit which didn't even show up 30 results down on ddg.

I should try copying the other way, but Google does seem objectively better (doesn't stop me trying to use ddg and only go to Google manually as a fallback).
The original poster did not necessarily mean to force such products on the entire world population.

Wealthy consumers are able to fund technologies.
Wealthy consumers are also able to be more discerning with purchases.

In the same manner as many nations skipped industrialization and computing stages, we can do the same with eco-friendly products. When Africa was ready, it procured mobile phones, not desktop computers.

Precisely as per the Tesla business model, it is sensible to target 'rich' discerning consumers to drive legislation and production in order to scale & mature it for future consumers.
I understand that, I’m simply pointing out I think it’s important. Great article regardless (I should add)
The grundig site has a Beko UK security certificate! I'm pretty sure the Turkish group renamed some of their old Beko electronic divisions, including radio, to Grundig after the takeover. Not sure about appliances as Beko already had decent presence at the cheap end of the market, so Grundig was maybe a chance for them to try to move upmarket a bit.

Takeover was around 2007 so you could possibly have one of the last "proper" ones. No idea which particular products or if any old Grundig products survived a while longer. What shows up in search now is nothing like the type or quality I'd have once expected of the brand.

The recursion limit exists simply to prevent the user-level code from exhausting the native C stack.

On the other hand CPython in fact does extra work because it also creates heap allocated frame objects (which essentially mirror the C stack) for debugging purposes.

I’m not sure what your point is. There’s obviously going to be thousands of different scenarios that I didn’t cover; it would be impossible to cover every imaginable use case.

> What if there is one team, but different developers (one working on the frontend, another on the back)?

Then presumably everyone in that team are full stack?(Otherwise it would be different teams in the same department) so it still makes sense to have a monorepo because you could have a situation (holiday, sickness) where someone would be working on both the front end and back end. Thankfully got is a distributed version control solution and supports feature branches so you can still have multiple people working on the same repo and then merge back into a developement branch.

> What if QA can test the API while the frontend development is ongoing?

Testing isn’t the same as released versions. You can (and should) test code at all stages of development regardless of team structures, git repo structures nor release cycles.

> What if the front and backends have different toolchains, and ultimately separate execution environments (server app backend vs JS running on client machines).

I’d already covered that point when talking about different languages in the same repo. You’re making a distinction about something that version control doesn’t care in the slightest about.

I think it’s fair to say any significant cross-project tooling should be it’s own repo (you wouldn’t include the web browser or JVM with your frontend and backend repos). But if it’s just bootstrapping code that is used specifically by that project then of course you’d want that included. Eg you wouldn’t have Makefiles separate from C++ code. But you wouldn’t include GCC with it because that’s a separate project in itself.

Ultimately though, there is no right answer. It’s just what works best for the release schedule of a product and teams who have to work upon that project.
if you did that, it would be boring.

The difference between a livestream of somebody's house and a soap opera is the storyline.

Without the story, only the world, the intensity is much lower and you would need the world to be much much more detailed to hold any interest. A real fractal of details like in a real world is much more effortful to implement compared to a good story.

True, although it seems like this place has gotten much more popular in recent years. Apparently there are more tourists on bikes than cars on the road nowadays. I have no idea what that practically means though, or how easy it is to pop off into an un-touristed area.
There is also value in customer trust. If a customer gets burned by a Google.com link, they are going to check next time they see such a link. Google would be better of if customers felt 'oh, it is Google so it must be safe'.
