To add a bit of context to the sibling comment, rocket stoves can work when made out of pretty much any material, because the air flow is not tightly regulated.

Batch box's purpose is to allow a more full-sized fire with the efficiency of a rocket stove, and there are several key differences to hit that:

- It should be made of a refractory material. Rocket stoves function perfectly well with plate metal or anything, really

- All dimensions, especially the air inlets and heat riser, must match a specific set of ratios to preserve the specific airflow needed to maximize burn efficiency. Too much means air will move too quickly, preventing full burn

- A choke point between the burn chamber and riser exists to slow down and funnel gasses and heat together. Without this, you don't have enough heat to get full combustion

Batch box burners tend to be quite a bit more fussy than a rocket stove to get going, though if a good portion of your exhaust rise is inside and pre-warmed, it should have a strong enough natural draft that starting it isn't much extra effort. I toyed around with the dimensions a bit myself and have something that works really well (cylindrical chamber rather than block), though I don't think I'm getting optimal efficiency out of it.

This strikes me as demagoguery unless an accompanying explanation is provided; i.e. just one of those sentences that is used to beat people over the head and make them feel crappy, establish social-professional dominance, etc.

If there are specific parts of the big picture you're not seeing and should be seeing, you should be told -- with reasonable clarity -- what they are, or at least given some very concrete and actionable examples.

If the implication is that you're just not understanding your industry domain, there's no substitute for experience and independently motivated learning. This takes time, and you can't bake the cake faster if you set the oven to broil, impregnate 9 women and get a baby in one month, etc. Your manager will just have to be patient.
Is it hard to add a source of hydrogen? In the images they have here it looks like there is a vat of water and it explicitly says it produces H2O and CO2 gas waste (though calls the CO2 harmless). That would imply there is a source of hydrogen here. (Not an expert, just legitimately curious so I can better spot snake oil)
Ask HN: How can I make beautiful, professional programmatic text animation?
I'm building a word game on the side, and I want to artfully and elegantly transform one word into the other, programmatically. The corpus of words is quite large, but there are a finite number of transformation types. (Example transformations would be shuffling or dropping letters)

Everyone seems to be either using something like Adobe After Effects, or the animations themselves tend not to look very organic or soothing and satisfying to the eye.

Is this something that can be done easily in modern CSS and Javascript? Is there any resource, individual, or group you can recommend for either learning from or contracting with to accomplish this?
Yeah, it's a useful scaling experiment given the improvement from GPT-2 to GPT-3.5 (base of ChatGPT), but I'd have to guess the "emergent capability" curve is flattening out at this point.

ChatGPT already does well when essentially regurgitating factually correct information, but the obvious weakness of an LLM is that when combining sources its just combining them linguistically so it produces fine sounding streams of often factually incorrect bullshit.

It's hard to imagine how GPT-4 will be much different unless there have been some fundamental extensions to the model architecture, or changes to the training regime. Presumably it'll do better in "search engine mode" where people are hoping it'll "understand" the subtleties of their questions in selecting what to generate, but hard to see how it'll avoid the "bullshit chained deduction" problem unless they've added a way for it to learn from it's own mistakes.

In terms of perception/disappointment, I guess it depends on individual expectations. If you want GPT-4 to be a better "search engine" than GPT-3, then you may be happy. If you expect GPT-4 to be "more intelligent" than GPT-3, then I'm guessing not so much. Let's see!

I've a hunch it may do well as the basis of an improved Copilot since this seems to be an easier subdomain.
This sounds great. Your VCS should fade into the background, rather than be front and center like git. Nobody should be breaking their flow, staging, committing, pushing as an ersatz backup, and then going back to coding. Teams shouldn't be bikeshedding on merge vs rebase, many commits vs one commit, etc. They should just be coding.

However I can see where a sort of "checkpoint" feature before performing a "hold my beer" change makes sense. A commit in some sense. `jam checkpoint` ... code ... `jam revert`

You should just be coding, and when the thing your are coding is done just do a single "squash merge (in git speak)" to the main branch.
You should be taking money out at your chosen rate, not depending on how those companies choose to allocate money between dividends vs. buybacks vs. cash piles vs. reinvestment. So treating dividends as reinvested by default makes sense to me.

They often would if they tried to access them like they usually do a filesystem, but for some reason people know a full table scan and N+1 queries are bad, but don't bat an eye at readdir and stat each entry in a directory (or worse, scandir+sort+stat).
> Corporations are made up of people, and people have causes they want to be charitable towards.

Why do people insist on using Coinbase when Kraken has none of these issues?
When I was in the security clearance process, the first step in the process was a 500 question multiple choice psychological exam (randomized order). The test is designed to have some level of error checking to make sure participants are taking it seriously (e.g. questions that would be expected to correlate). Near the start of the exam was a question "do you have back pain", I answered "no". Near the end was the same question phrased slightly differently, I answered "yes". When in my subsequent interview to discuss the results, the interviewer questioned why I didn't answer consistently. She seemed to accept my answer of "I had been sitting in an uncomfortable chair for 2.5 hours by the time I got to the second question".
So, "given when then" style tests (e.g. Spock) plus a descriptive test name. Or more than that?

Well... COVID claimed my mother's life about 2 years ago, and I've had multiple family members contract COVID, including at least one family member who's had it twice. So in that sense, it's been a pretty big detriment to my life. On the other hand, I've either dodged it completely, or if I've had it, it was a completely (or very nearly completely) asymptomatic case.

Certainly the ~2 years of extreme stuff with lockdowns and all the supply chain problems, and this and that were a big impact on life, emotionally, mentally, and so on. But around here, life seems to have gone back mostly to normal for a while now, and I'm back to most of my old routines as far as going out, socializing, shopping, whatever. And that makes me very happy, as I get a little stir-crazy being stuck at home all the time.

If there are any positives to take away from it, I did learn a lot while stuck at home so much, and my dayjob has maintained a "3 days at the office, 2 days at home" work schedule even after Return To Office. And I re-kindled my passion for freshwater fishing during the "peak COVID" period. I spent a LOT of time outside, bank fishing on small creeks and stuff near me. And now I've kept that alive to some extent. In fact, I just caught my first ever rainbow trout a couple of weeks ago, which was cool (freshwater trout are not indigenous to my area, but the NC WRC stock certain ponds with trout during the winter months).

I got back into a lot more bike riding as well, both mountain biking and road cycling, and also trying to focus on keeping that up even as we move to "post COVID" (if such a thing can be said to exist).

I find it worrying that most comments seem to follow gut feeling and common sense when dealing with psychological issues like that, instead of relying on therapy and research.

If inner critic gives you real trouble, the best way, by far, is to start working on such problems with a licensed mental health specialist.

Second best way is to catch up on modern research in psychology and psychotherapy. (I'm generalising below with most important knowledge I have on the topic based on my replies to other comments.)

In modern therapy it is considered that at least some of the inner critic issues are responses to past traumatic events and emotional trauma. It tries to help you avoid doing something that hurt you in the past, like a legacy broken failsafe mechanism.

Possible root causes might include:

- Complex PTSD [0][1]
- Childhood emotional neglect [2]
- Traumatic stress [3]
- Style of your upbringing and some other issues from the past, including learned responses to life stresses [4]

Sources referenced above are very useful in 'debugging' yourself, are widely known, and are written by psychologists.

This knowledge is in part a modern (last decade) evolution of older Cognitive Behavioural Therapy ideas[5] from the 1980s. OP article describes typical CBT strategy. CBT, while being helpful to manage critic-related problems, rarely addresses any of the underlying root causes.

If you don't want to dig deep into root causes, I want to explicitly highlight [4] as it does a great way of summarising core CBT and ACT (Acceptance and Commitment Therapy) ideas, and helps to address the critic issue directly via many actionable strategies.

It should read “If I was alive in 1923 and invested $8M in 100y bonds that return the exact rate of inflation, I’d have $140M today”

The input situation is dreadful and I couldn't stand the delay with AirPlay2 either.

However, combined with an AppleTV 4K (2nd gen upwards), HomePods can be used as HDMI eARC devices. This enables playing sound without delay from any HDMI output.

In my setup I use an eARC capable HDMI splitter and a $10 Thunderbolt to HDMI adapter to create an audio device for my mac that has virtually no delay. The video output of the HDMI adapter is set to just mirror my first screen, which avoids additional video processing load.

For what level and in which area? Books like _Methods of mathematical physics_ can be both too hard and irrelevant to your needs. For starters,

To become a better problem solver with high-school level maths:

- Polya's How to Solve It.
- Books of your choice about math contests.
- Concrete Maths. I understand that this book is taught in college, but it requires very little advanced maths, and its techniques are hugely useful for high school students too.

To hone my intuitions. I learned it the hard way that college maths were different from high school math: in high school, my teachers painstakingly drilled intuitions into us with very targeted explanations and tons of well designed exercises. In college, we won't get such luxury. So, it's really up to us to understand mathematical concepts intuitively before diving into technical details. For that matter, the following books helped me a lot:

- The visual series. Visual Complex Analysis and Visual Group Theory, for instance
- Pinter's A book of Abstract Algebra
- Strichartz's The Way of Analysis
- Linear Algebra Through Geometry by Wermer. The book offers a comprehensive geometric interpretation to linear algebra concepts. It's especially helpful for me to understand quadratic forms.

To understand Analysis better. This area is vast, so I'll skip recommendations of excellent text books:

- _Counterexamples in Analysis_. Those counterexamples in Analysis play a huge role in helping me truly appreciate the intricacies of Analysis. Similarly, books like _Counterexamples in Probability and Real Analysis_ are of great help too.
- The Way of Analysis by Robert S. Strichartz. This books is AMAZING for laymen like me. You'd want someone to *explain* how concepts emerge, and how intuitions evolve.

To become good at maths by doing maths, so the following books used to help me a lot:

- Problems and Proofs in Real Analysis
- Putnam and Beyond. I still suck at maths, but those well designed problems in Putnam really taught me how to seek insights in higher maths.
- Piotr's Problems in Mathematical Analysis. But really, any problem books that challenge you will do. I'd recommend you find problem sets from the website of university courses. They cover essential techniques, and will not be as overwhelming as the books.

Also interesting to note is that (AFAIK) approximately zero "defundings" have actually happened. In fact many have increased, spearheaded by President Biden himself.
> If I was alive in 1923 and stashed away $8 million in cash it would only be worth about $140 million today.

Stashed it away as cash where? If you had $8M in 1923 and kept it under a mattress, it would still be $8M today - the difference is due to inflation - in 1923 you would've been the equivalent of a Billionaire today - and today... you'd have $8M.

I think things like this matter a lot.

If you invested in treasuries or only had a savings account with interest - you're going to get eaten alive by inflation, and over a long period of time - your wealth will decrease enormously - maybe as much as 50%+ (with a savings account).

If you instead had invested in the S&P - and it did what it did over the last 100 years - you'd have 2-3x what you started with in real terms.

Although, past performance != future performance. No one knows what the future will hold. Maybe the US won't even be around. Maybe we'll move to socialism. Maybe private companies get overrun with crooks and everyone loses most of their money because the whole S&P goes Enron/Wirecard. Who knows!

But my guess is I'll be better off with equities than cash medium & long term. And fortunately, I'm not too concerned about short-term.
> you don't need to remove ambiguities if you can collapse the ambiguities into equivalence classes.

It still leaves users who don’t know or can’t assume that normalization is applied worrying about which character exactly is being displayed.
Seeing inclusive terminology as a punchline, yes, I can see that. But a sign of left-wing lunacy? This response has some whiff of "bothsidesism", drawing a perceived equivalence between the behaviors of each party. If you didn't mean it like that, I apologize for misunderstanding.

That being stated, there's an objective difference between one party promoting inclusive terminology while the other promotes forcing a 10-year-old girl to give birth after being impregnated by rape. I know that latter issue wasn't mentioned, nor is it a universally held policy for all Republicans, but neither is support for inclusive terminology, and I bring it up to demonstrate the contrast of some views. Take even the most far-left view of a Democrat in Congress and it's to, what, provide universal healthcare? UBI? For this reason, I agree with the previous poster that one side seems like they're at least thinking about making life better, while the other seems hell bent on making it miserable, and sometimes in the craziest ways.

To be honest, I find the inclusive terminology more annoying than helpful, and I was born, grew up, and live in the Bay Area, a few blocks from where the Black Panthers were founded, to give an idea of where I'm coming from. But I feel like -- and this is going to sound a little strange -- Republicans harping on that topic is like sushi in the 80s. Remember movies/media from back then where eating/enjoying sushi was a sign that one was an effeminate cosmopolitan, bourgeois, and all-around weird person? Now it's in supermarkets in rural Virginia (yes, I've seen it there). At some point it will stop being a punchline; it will melt into the background and nobody will think much about it anymore.
I agree the supreme court is the wrong mechanism to regulate social media. Congress should. I also agree its hypocritical of the supreme court to do it, but its not hypocritical to want free speech on social media despite billionaires controlling other political areas because billionaires controlling politics is not an American value and free speech is.

Coinbase is terrible. I’ve tried signing up and they won’t let me because they’ve tagged my SSN with fraud but won’t tell me why. CS is nonexistent. But it’s okay, thanks Coinbase for helping me avoid you. Terrible company and service.
Unless you use an exchange. The best way to handle payments would be direct transfer from one personal wallet to another. No exchange necessary. No red tape. Buying the Bitcoin with fiat so you can put it in your own wallet for direct transfers is the problem. You generally need a centralized exchange for that. Also, the person you transfer btc to will generally need a centralized exchange so they can convert to fiat and actually use the btc. The whole ecosystem is a mess for people who just want to use it as a way to transfer funds.
People aren't interchangeable. The company might want to layoff 10%, but they don't want to layoff just any 10%. They will want to layoff people in positions and teams that they want to do away with, and to the extent some people are interchangeable, they would like to layoff those that are the least productive.

If you announce layoffs before telling people who will get cut, the people who tend to leave voluntarily are often those most able to get jobs elsewhere because they are high performers in positions that are hard to staff -- so exactly who the company wants to keep.
What's the word, tongue in cheek? I meant it sincerely but phrased in a sarcastic tone. I unironically do this and it's saved me from two phone breakages. I cannot understand how anyone would trust any of their accounts to a single physical device that is routinely lost, stolen, or broken.

My 2FA token is just a second password that doesn't get sent over the wire directly -- it's almost like a private key where you auth via challenge... wait a minute, thought you could sneak PAKE on me?!
We definitely need something to “work” on, but most of us don’t have the luck/privilege to work on something they truly find challenging and motivating, what they would genuinely continue without any monetary compensation. With that said, I think most people are just not that motivated for anything, and they also would need something to spend their time on otherwise we would live in very chaotic times.
Given up on Coinbase long ago. As a crypto user, it literally stops working during periods of price volatility.

Kraken is my go to, but I have no idea about their business account support.

You also should use Algorand or something imo and avoid sending BTC. USDC is a good option to send dollars, if you use AVAX network it should be nearly instant.

But honestly like others said best option is likely Wise. I get paid through there from my U.S. employer, never had any issues.
