I'm working from my personal experience. If you've never had something similar happen, then good for you.

I'll admit that it's quite likely that advertising algorithms are sophisticated enough to anticipate our needs based on previous behaviours with uncanny precision and timing.

But I don't trust to that, given the proliferation of cheaply made gimmick apps which contain embedded third party ad libraries.

Since I have no way to verify either way, and my experiences are echoed by my social circle, I personally think it best to assume the worst of my device.

I will mention that a recent study* concluded that most apps with microphone permissions will not unduly access do so. This has been taken by articles I've read to dispel the urban legend of the listening phone.

But, given that the tests lasted 5000 random user events (at ~16mins), on a more or less clean device, and as the study says

"…we did not use pre-configured text
inputs, which vary across apps and require substantial
manual effort; instead, we relied on random interactions.
Accordingly, we miss some events that only human in
teractions trigger, e.g., in apps that require login."

I don't think it can be taken as an authoritative final answer. Especially given that the devices had no pre-existing identities apps to latch onto and inform about.

The study also looked principally at network traffic, with a focus on detecting conventional media formats. This is fine for detecting the transfer of visual content, and audio. But it doesn't account for the device itself listening for keywords, and reporting them, or partially resident models, which would perform their first few operations on-device, before transfering their outputs for final processing server-side (mentioned in their study's limitations section).

The difference between rowstores (Scylla/Cassandra) and columnstores (Clickhouse) comes down to the physical layout of data with batch/vectorized processing and other techniques.

There will always be a 1-2 magnitude increase in performance regardless of the data. They also used the same number of rows, except with smaller cardinality in measurements which would make an insignificant speed difference.
Considering that we really need to reduce emissions every year by about 15% by now it is not enough at all https://mobile.twitter.com/CarbonBrief/status/12132723324640...
There isn't much point to the inverse. You load pages, including all the stuff you don't want, then disallow it. Closing the barn door after the horse has bolted so to speak. You also have to remember to check every site you visit, which nobody is going to do consistently. With disallow by default, it is obvious you need to look because the site isn't working. While I was required to do this for work, I found myself doing it on my personal systems too, because things are in general more pleasant. A surprising amount of sites work just fine for the purposes of browsing, and many more just requiring one or two domains added to the whitelist. Often leaving out large amounts of crap from several ad servers and metrics collectors and video streaming I usually don't want to bother with and popup banners telling me to disable my adblocker and font tweaks because I'm obviously incapable of configuring my browser to be most usable to me and 'tagmanagers' which apparently do absolutely nothing and widget for forms I'm not interested in filling out. I've more than once found enabling JavaScript makes problematic pages worse.
It's worth noting that TPUs are available for free on Google Colab.

Yes, and you can also get a research grant, which gives you several TPUs for a month. But that does not mean that you can easily deploy TPUs in your own infrastructure, unless you use Google Cloud and suck up the costs (which may not be possible in academia).
> Look at the context.

The context is extremely partisan twisting of the justice system on all sides. Normally DA's have complete discretion to drop charges as they see fit. Because of the partisan outrage a Republican special prosecutor has been appointed to overrule the prosecutor and now he's on a witch hunt going through a year of Google records trying to find everything incriminating, this is a farce and high level corruption
Fun fact: you can identify these drugs as Monoclonal AntiBodies due to the suffix -mab.

This category has been incredibly successful against a wide variety of debilitating illnesses like autoimmune, cancer etc. My doctor told me that surgery for arthritis is a dying specialisation in medicine, because the new drugs like infliximab are so effective.

The discovery of how to produce them got the Nobel Prize in Medicine in 1984, and the more recent discovery of how to tailor them via directed evolution got the Nobel Prize in Chemistry in 2018.

Not to diminish what a dunce this guy was, but the only crimes currently punishable by death in the US are ones in which the victim has died. And maybe treason, espionage, and other weird crimes against the government. Those are unclear at the moment.
So is Microsoft, at least, on Linked-In. I tested it last year and deleted my profile. Had a friend check and everything was gone...Everything including public posts.

LinkedIn has a remorse period of something like 21 days. And I had plan to test recovery process also. Then got busy with a contract and was too late to recover. It's awesome!

I think any global IT company must deal with GDPR kind of like most automakers in U.S. follow California emission standards. It's easier to create a policy for all than create "one off" policies for a geopolitical region.

Efficiency is only one measure of a storage system's overall usefulness.

Other dimensions are total capacity, total cost, ramp-up / ramp-down times, storage and delivery rates, and various elements of technical complexity.

Batteries offer moderate-scale, fairly-expensive, moderate density, and relatively low storage and delivery rate, energy storage. They're exceptionally useful for mobile uses (from handheld to vehicular), but may not be as desirable for stationary systems.

There's a spectrum of energy storage options, ranging from capacitive storage (very responsive, but also expensive, inefficient, high-rate but low-yield.), flywheel, battery, physical mechanisms (pumped hydro, compressed / liquified air energy storage), and chemical (electrolysis, fuel cell, fuel synthesis).

If you're storing energy when it's abundant and releasing it when it's highly scarce, net efficiency doesn't matter nearly as much as matching generation and load capacity. Losing energy because you don't have the capacity or capture rates means a theoretically highly-efficient process is actually lower in net efficiency.

The duration of energy storage, ranging from a few seconds (capacitors) or minutes (flywheel) to proven-at-hundreds-of-million-years (hydrocarbon chemical energy storage) also matters. If you're trying to smooth out transients, capacitors or flywheels (mimicking "spinning reserve" or inertia) are your tool. If you're shifting over a period of hours, batteries, CAES, and pumped hydro come into play, with the latter offering long-term capacity of months if needed. Fuel synthesis could in theory allow shifting by years or decades, with very stable storage, though a net round-trip efficiency of ~15-20% (losses in synthesis compounding Carnot efficiencies of thermal energy generation, if used for electrical generation).

I've got concerns over LAES, well reflected in @aurizon's comment: https://news.ycombinator.com/item?id=21996594

Thermal losses in cooling, and the need to supply energy to re-heat the liquified air, make me question this method.

Re eye diseases / blindness, there is at least one approved gene therapy for a form of congenital blindness, luxturna: https://www.fda.gov/news-events/press-announcements/fda-appr...

the eye is one of the areas where gene therapy delivery is currently feasible. other areas include the CNS using AAV9. Perhaps the most impactful gene tx yet approved is Avexis' Zolgensma (Avexis was acq by Novartis for $8-9B in 2018). Zolgensma is a potential cure for spinal muscular atrophy, the leading genetic cause of infant death. Zolgensma did $160M in its first full quarter on the market

Other areas where we will likely see approved gene therapies soon include blood diseases like hemophilia, beta thalessemia. In addition to blood, eye and motor neurons, the liver is a popular target for gene therapy as all of these tissues are easier to deliver gene tx to with current technology

Delivering gene tx to other tissues is not really feasible as far as i know at this point

> Repurposed to use more modern AND sustainable agriculture techniques

This answers my question. I was wondering if you were suggesting that arable land be repurposed for carbon capture rather than food production, thus the question, how to feed 11 billion people (projected peak world population).

In any case, I think we're making arguments in slightly different directions. Surely, there are more sustainable farming approaches such as no-till, etc, which saves the CO2 emissions.

Let's presume we've use those approaches and have a field full of corn (or wheat, or what have you) ready to harvest with zero carbon emissions and slightly reduced yield. Then what?

That corn still needs to be harvested at 3.8 gallons of diesel per acre and then transported to market.

> questionable appetite for meat

As most other countries, especially developing ones consume way less meat, this is a US specific problem, though admittedly it makes a significant contribution to greenhouse gasses.

> The problem of world hunger is NOT a "global food production limit" problem

The basis of my arguments has less to do with world hunger as a problem that exists today and more to do with the fact that peak global population is estimated to be 11 billion folks. Feeding that population will be difficult to do with yields well below current industrial farming practices.

> we won't, since we have established that the traditional methods are unsustainable. People will die, either from hunger or from climate-related catastrophes.

We should hit ~10 billion by 2050, I doubt there'll be massive climate change related catastrophes by then. 11 billion is projected by 2100, and well, unless something changes then we likely would.

In any case, thanks for engaging in this discourse. Likely, we agree more than not that more sustainable agriculture practices will be needed.

Thank you!!! I appreciate the effort here and have followed Dave on Youtube for long time.... but have spent very little time on the precious plastics webpage. So if my questions are better answered there, please feel free to point me in the right direction.

I am super interested in starting a small space... as in my garage. I have a place on the side of my yard where I could store close to 10 pallet sized "containers" where I could store various plastics.

Admittedly, I have been hesitant to purchase the required machinery to process the plastic for selfish reasons. However, my wife and I have discussed the need to do something completely altruistic to show our children and I think this would satisfy more than a few "conditions" that would enable an investment in said machinery.

That all said, how would you go about collecting plastic? I live in a suburban city that has a recycling program. Should I ask businesses? Do I need to cold call to get steady supplies? Picking stuff off the side of roads and whatnot seems good for a while, but how would I make dent if I cannot secure a reliable source?

I've lived in Pittsburgh my whole life and I can't recommend it. It's just a really unhealthy place. I 100% believe him about our air quality. I visited Seattle recently and noticed on the second day that breathing felt so much easier. I don't have any data but I know how I feel. Some friends who moved here for grad school have said the same thing, and some even have been diagnosed with adult asthma after moving here.

Our water quality is awful too, we have boil advisories a few times a year after they find lead. They just approved fracking in the Mon Valley against the public's wishes, and closer to the river than environmental groups recommended, so it's just gonna get worse.

It's an incredibly car-centric city, so there's new pollution being spread everywhere every day. I've been trying to find a job elsewhere for 2 years, hopefully eventually I can leave. There are other up-and-coming cities more worth your time.

> As a male software engineer, I feel as though no-one is welcomed or encouraged. I feel as though women are reacting to industries that have always been harsh and unwelcoming and feeling uniquely victimised.

Have you ever had someone grab your ass or try to kiss you without consent in a professional context? Ever had a corporate officer seem interested in hiring you, call you in for an interview, ask you on a date, and then decide not to hire you when you rejected them? Ever been told on the first day by a new boss about their open relationship with their spouse, and their search for new sexual partners? Ever had a coworker make an overtly sexist joke about your gender to your face? Ever been propositioned for sex by a stranger at a conference? Ever heard a friend explain that “I would never work for a woman boss. No offense, you’re not like most women.” Ever been denied a new job or a promotion because the decision-maker thought you might have a child within the next few years? Ever been the clear expert or authority in a meeting with multiple people and been repeatedly interrupted by someone asking the clueless novice next to you to explain what you were just trying to say? Ever had a novice badly try to explain the content of your own book to you, even after you mentioned you were the author? Ever gone to speak at an event and had someone ask you which speaker was your spouse? Etc. etc. ad nauseam.

If none of the above, then you probably are misunderstanding what people say when they claim to feel frequently unwelcome.
I can relate.

Some options I'd suggest:

- reading a book / listening to an audiobook

-update documentation

- some kind of meditation like activity for shorter jobs

Also, try to make the system send a a reminder when the job is finished.
Boyle's Law says that compression and temperature reduction are equivalents: PV = nrT

That is, increasing temperature is equivalent to increasing pressure, and vice versa: decreasing either is equivalent.

The problem with liquifying -- cooling -- a gas, is that:

1. You're removing thermal energy. Which itself cannot be usefully stored. So you're losing that unless it can be applied to some local low-quality heat process.

2. Re-gassifying the liquified air requires energy. If you've managed to store (some of) the removed heat, you can apply that. Otherwise, whatever you're using to introduce heat to the liquified air will itself get very* cold, very quickly, and eventually reach thermal equilibrium. Alternatively, you could apply a fuel-based heat source sufficient to boil off the liquid, but that's going to cost you energy.

Depending on the temperature of the freshly-generated gas, you're also going to be chilling whatever generating process you've got (probably gas turbine), which means both metal embrittlement and potential for frosting if there's any degree of water vapour in the air.

The more usual form of air-based energy storage, compressed air energy storage (CAES) likewise has problems with both heat loss and chilling on expansion. Compressing a gas heats it, and that heat will tend to escape to the environment, similarly to the case for chilling. On the energy-recovery side, expanding the gas to run a turbine will cool it (and the turbine) rapidly. Many CAES designs incorporate natural gas simply as a heating function to heat the freshly-expanded gas, meaning the storage system is not a no-fuel system, though it requires far less fuel than a conventional natural-gas generating plant.

The biggest issue I have with the system as described is that the re-expansion of liquified nitrogen isn't free, and requires a source of external heat. Given the phenomenally cold temperature of liquid nitrogen, any passive heating design will rapidly approach thermal equilibrium with the stored medium, limiting the rate of net energy release.

Yet Prometheus runs out of steam pretty quickly if one has a need to aggregate metrics from multiple regions or retain metrics for a lengthy period of time.
The added value of build tools is that javascript are increasingly the assembly of the web and more of a compilation target than something you deal with natively (using the term loosely here since we are talking extensive interpreter and compiler hacks that are needed to make this interpreted language feel fast-ish).

With web assembly maturing, interacting with this mess is becoming increasingly optional. Also languages like typescript and kotlin that compile to javascript add layers of much needed sanity. IMHO any project not using that is doing it wrong at this point. I'm very aware that this is opinionated and even offensive to some but after 2 decades of "maybe this will fix it" type innovation in the javascript world, I have very little patience left for that. The less I'm exposed to that smelly pile of manure, the better IMHO.

So, my recommendation: avoid this tool and use a sensible compile, verify, test, minify, and package it up style tool chain like all the grown ups do these days. I agree, tools for this are very much a cluster-fuck in terms of complexity, lack of any sane defaults that are actually good enough, usability, and performance but they're better than nothing.

In an ideal world, you'd not have to download hundreds of MB of layers of tools around tools that try to fix and work around each other. But there's no good technical reason to skip using them entirely. There's no sane excuse to skip sanity checks, type checks, static code analysis and running tests (and designing such that you can actually do this in a sane way, which seems to be hard with JS). Skipping that is immature and irresponsible. I don't tolerate it in my own projects and have no patience for self styled full stack js ninjas claiming their code is fine. It's not anywhere near fine.

It is not unusual in academia to patent all innovations with potential commercial applications. At least in Canada, universities typically have innovation centres whose main job is encouraging and helping professors, graduate students, and other researchers patent their innovations and commercialize them (e.g. by licensing the patent). It is not sinister, it is normal procedure in academia.

They'd better be operational soon, because their production and delivery generated a bunch of emissions upfront - in China, presumably - that'll take years to compensate.

It's something to consider anyway.
