It takes 9 acres of solar panels to light 1 acre of vertical farm crops.

Theoretically, you could cover all of Nevada (~70M acres) & Arizona (~73M acres) with solar panels.

That would only give you enough vertical farm space for ~16M acres, and apparently the US only has ~10M acres for farmland for fruits & vegetables.

Point being - this seems implausible - and I'm not sure how you work around that.

IIUC, it takes about 1 acre to produce ~.12MW solar (obviously differs based on where the panels are). The world installed 168GW of solar in 2021 - so that's 1.4M acres of solar.

It'd take 100 years of solar production to cover that much area with solar panels.

And for what?

Cattle uses 4.5x more land by itself. We use 3x as much space to grow most of our calories (grains and oils) - replacing that with vertical farms seems like something from an alien civilization that is way to far away to imagine.
To be fair most of that decade has been a state-declared drought (2012-2016) :) and I believe the interceding years were also usually low in terms of precipitation even though they didn't meet the formal definition of a drought.

None of that detracts from this of course.

Eh. I predict that little will change in the broader tech economy because of AI in 2023. Over the next 3-5 years, yes, but not the next 12 months.
The axiom of choice is the topic of one whole quarter of set theory in my undergraduate years. I still don't think I fully understand it. By "fully understand it" I mean achieving the level of proficiency of my professor who, upon hearing seemingly any theorem encountered in undergraduate study, would immediately tell you whether it requires Axiom of Choice, merely Dependent Choice, Countable Choice, or doesn't require Choice.
Yeah, that's super common. Apparently you can avoid it entirely by practicing half an hour a week with QWERTY, but who has time for that? I find that it's not much of a problem these days, because of phones. I keep my mobile keyboard in QWERTY, so I always have some memory of where those keys are, even though the finger movements aren't hardwired into my motor cortex anymore.

I just checked, and going into it cold, I can squirm at about 35 WPM on QWERTY (vs 130 on Colemak). It's annoying, but serviceable if I'm using someone's computer for a few minutes. For a longer situation, if they're using a mac or linux, I can switch them to Colemak in about thirty seconds (I had to do that in some onsite interviews a few years back), and if it's Windows, having to use QWERTY is probably the thing I'm least annoyed about.
I recall my father hating technology because the irrigation systems for crop circles would call him when they stop functioning at night. Likely could just wait until morning for a motor or solenoid to be replaced.
I'm afraid I'm going to have to disagree with you that a software engineer needs better problem solving skills than a doctor. Strongly.

I don’t have hiring authority, but I was on a lot of technical interviews at my company for a while.

When people put their GH handle on their resume, I definitely checked it out. Sometimes I would even see if I could get it running on the first try. This has been an indicator of some of practices they have.

But it’s only ever a small piece of the picture. Some people push their code to github when they are very junior, and it doesn’t represent where their skills are currently at.

There is the issue of forgery, but I lump it in the same category as lying on a resume- the deception is equally as serious.

The first tweet casts it in light of an ongoing competition of extreme radical predictions, so I expect it is expected to be taken nonseriously. OTOH, its also not a source that posts casual jokes, there is a serious propaganda purpose in each of the items chosen – like much advertising and propaganda, its not the literal message that is the point, but the ideas it plants below the surface.
From hobbyist I went and did a bachelors in business information technology. I also did some coding for a charity and made some online apps for the organisers. On the degree program, I did work experience, and then afterwards applied for jobs.

I guess you can skip education, but where I come from, it's hard to get employed without previously working some place else, which is why most people do related work training (usually unpaid or poorly subsidised by the employment office). Educational institutions usually tightly knit into the industry with some companies running on a revolving door of students.

One other thing. Having a good github presence goes a long way. Make pull requests, interact professionally. People interviewing you will be reading all that.
These are physical properties that can be experienced (although there is some risk) for voltage you can touch a Van de Graaff generator, for current you can touch a battery to your tongue.

That's the way to understand electricity without analogies. :)

Anyway, voltage is always measured between two points (one is typically called "ground" but that's not important here.) It's a difference. (A difference of what? No one knows. That's just the way it is.)

Current is always measured through a single point. It's a count of the charge flowing past a point per time unit. (What is charge? No one knows. "Charge" is just a name for the mysterious something that "voltage" is a difference of...)

When electricity moves it obeys a (very simple) Law called (Ohm's Law) e.g.:

E = V/R

The current (E) is the Voltage divided by the Resistance.

E.g. is I have a 5 Volt power supply and I put a 100 Ohm resistor across it (remember that voltage is always between two points) then 5/100 Amperes of current will flow through it.

Also, If I take just the resistor and drive 0.05 Amps through it, it will develop a voltage of 5 volts, as measured from one end of the resistor to the other end.

Now if that doesn't help you, remember the advice of John Von Neumann to Felix Smith: "Young man, in mathematics you don't understand things. You just get used to them."
Yeh, what @rrrrrrrrrrrryan said, I think it's no great problem either way :-)
To add some context: Arlo just sent out an email announcing EOL for their older camera models that were sold as recently as 4 years ago. The cameras will not receive any firmware updates and will not work with the cloud storage. They were sold with a "7-day free cloud storage" promise. Beware buying any new cameras from them as they will not be supported for long.

I launched a self-funded startup to focus on technologies I developed that have the potential to deliver significant benefits to indoor farming operations. We launched in 2019, yet, the pandemic put everything on hold for almost two years.

This year we finally completed our first installation (paying customer) at a farm in Singapore. Yes, we are US-based. Due to circumstances and opportunity our first installation happens to be abroad.

I applied to YC for multiple batches (I don't remember if it was three or four times). Rejected every time. I think it was an algo-rejection far more so than someone explicitly rejecting the company. We have shipping hardware and software products, a sizable first sale and at least one happy customer. This isn't an idea, it's a validated opportunity with solid execution. Our customer is looking to expand and wants more of our product. Lots more. We also have a product plan that will expand into other related domains.

I don't know if I have a solid opinion about SV and agriculture. Starting 2023 I will be out there making a solid effort to seek funding to be able to press on the accelerator. I think $5MM would be about right. I will also be focusing on IP, which, like it or not, can be crucially important when dealing with hardware that could potentially unlock a billion dollar business.

My only attempt at fund-raising has been applying to YC, conversations with our customer (who might be interested in investing) and a good friend of mine with deep and wide business experience in globally recognized companies. I guess I will soon learn what SV has to say about indoor farming startups.

Being self-funded is great in that you can just drive and not worry about anything that might compromise your ability to focus on the mission. That said, at some point, if you are going to grow, you either need a series of massive (and profitable) sales to supporting customers who will wait for you to deliver (hardware takes time to build, etc.) or a strong cash infusion to front-load development and manufacturing.

In looking at this industry I see companies who have raised hundreds of millions of dollars, even over a billion, and are flaming out. As an SV outsider, I see this as a syndrome of sorts. I view it as companies who might not have a reasonably solid business or product plan just trying to, in a way, force their way into a market position by burning cash. This is very, very different from self-funding a startup, doing all the R&D, manufacturing and shipping product, having a satisfied customer who wants more and, at the same time, walking away with a ~33% gross profit margin. I can understand burning cash to accelerate, yet, I think, the fundamentals have to be there in the first place. If I were to guess, I might say that this could be the part a lot of SV startups get wrong.

> people should come to terms to the fact that everybody is moving to cgnat and the world is not falling apart as they said it would.

As someone who's behind CG-NAT, I agree that the world is not falling apart. It is, however, very inconvenient.

The IPv4 Internet has more fluctuation in latency - I imagine it gets worse in periods when many more connections are having to go through the ISP's CG-NAT router, and/or when a lot more volume of data is going through that same bottleneck. It's not the end of the world, but it's not ideal.

On top of that, my IPv4 traffic is bundled together with a cohort of cusotmers whose Internet behaviours I know nothing and have no control about. This affects my reputation on things like CAPTCHAs and other forms of access control. It's not the end of the world, but it's not ideal.

I can't get into my own network from an IPv4-only external network without resorting to routing contortionism. It's not the end of the world, but it's not ideal.

CG-NAT requires expensive and power-hungry equipment, which in turn means more maintenance, more complex infrastructures, more equipment failure and replacement and increased energy usage.

It's not the end of the world.

But it may well be contributing to it.
Cool - but there is no proof that these demo songs are out-of-sample, and the trained model does not seem to be available in the github.

If I am understanding correctly, the github code doesn't contain the code to train the model? [1]

The paper also doesn't seem to be peer-reviewed? (I guess it is pre-review, since it is on arxiv only 2m ago)

No disrespect to the authors - looks like a really cool project - I am just a bit suspicious without seeing any performance on user-submitted data.

Makes me wonder if there's a future where we can offload this cost to users local machines/servers. Eg if i can download a slice of their index, for a fixed price, then maybe the cost of per-search compute is better? I'd get more privacy, they'd save money (maybe), etc.

But it depends on what the true cost is. Is it indexing? Or actually searching?

> If you haven’t run at all your entire life … Obviously that’s not the case for you

Care to make any more assumptions? I practically hadn't run until ~35 when I was significantly overweight, [checks chart] actually officially obese, currently 44 & a bit overweight¹² and running regularly (including doing the occasional ultra event). I know many people with a not dissimilar history and away from anecdata there is plenty of evidence that running is beneficial more than it is detrimental in the general population⁰.

As I said prior: “There is as much evidence for running helping the joins in later life (assume you start earlier) as there is for the opposite.”. I know I know, [citation needed], but as the claim for running being bad for the joins generally was made first: I'll show you my citations if you show me yours. Or just keep downvoting and/or stating I know nothing if that makes you feel more correct.

I agree with everything except the staff Aug part. Anecdotal I know but I myself found a subcontract(!) as my first solo gig that easily beat my previous fulltime jobs pay, which weren’t peanuts either. And this was just Rails web dev.

My impression is that you can pretty easily beat fulltime pay doing fulltime staff aug, except faang salaries. Of course it helps if you have a spouse with health insurance.

I once saw type checking presented as kind of an alternative to unit tests which doesn't rely on the assumption that developers write good tests, and I really like that viewpoint. A powerful type system can prevent many bugs, doesn't need additional test code and doesn't make any assumptions.

Of course it's not necessarily a full replacement, but it's definitely better and more time efficient than bad tests.

> It starts off saying here are conservatives guesses for 2023.

No, it starts of with:

On the New Year’s Eve, everybody’s into making predictions

Many come up with futuristic hypotheses, as if competing to single out the wildest, and even the most absurd ones.

Here’s our humble contribution.

What can happen in 2023:

“Conservative” is not mentioned.
Is it urgent? If not, just keep programming things you like. I wrote a video game and published it. That got me a job in the USA. Sounds like you enjoy programming so find something you want to build and build it.

Planar-magnetic drivers certainly sound different, but the “plucked” effect from them is so obvious I’m not sure it’s actually lower distortion or just something people like because it’s noticeable, kind of like a tube amp.

My Anandas do sound good in general too, but the entire class of headphones isn’t technologically advanced at all. They don’t have consistent reproducible sound because different people have different head shapes, background noise levels, are wearing glasses… fancy drivers with more theoretical bass can’t make up for not having an ear seal.

Plus they look like you’re wearing football helmets on both ears.

(AirPods Max are the only product I know of that claims to do something about this. Though I don’t think they sound great, I do think noise cancelling closed headphones sound better than open audiophile ones in any reasonably noisy location.)
I remember watching some North Korea documentary where an eye surgeon was visiting to do cataract replacements. He set up in some community center and had dozen of people waiting for surgery. It can take about 10 minutes to perform the replacement and you can leave pretty quickly afterwards. It's an amazingly simple surgery that has a massive increase in quality of life for the patient. The only aftercare is an eye patch and drops to increase tear production to help heal the incision. Once a doctor has all the equipment set up, they could easily do a hundred replacements over a few days. Add to the fact that these doctors and nurses are doing work in third world countries where they may be there as volunteers and the price of the surgery is massively reduced.
Russia is not going to feel secure ever, even if they take Ukraine; it's more, there's always more, Georgia, Moldova, the Baltic states, Poland, Slovakia, Czech Republic, Romania, Bulgaria, etc

On the Russian state television the message is loud and clear, they want to reinstate the whole Eastern Block.

RF will never stop with this Imperialist conquering shit until they'll fall apart into dozen or more states.
The judges who trashed years of serious investigations because of some bullshit jurisdiction technicality, allowed the corrupt leader of the most scandalous party in the country to run for president and did everything in their power to get him elected? Yeah, just looking out for proper due process. Absolutely.

Bias? I don't give a shit, "kid". Do you have any idea what it feels like to have a president you know is a criminal rule over you? It's one thing to suspect, it's another thing to know. And he will rule over us, regardless of elected congress or senate, because the supreme court judges will force whatever law he wants into effect. Do you have any idea what it feels like to watch videos of prisoners cheering and drug traffickers celebrating with gunfire after his victory?

Huh? You think that math is not tied to real-world problems? That it's not useful for modeling the real world? It's not like programming is doing something inherently different.
