Solar Power Decline: Why the Industry Is Struggling

Underwater things are expensive to maintain, nothing is 100% waterproof, so rust rust rust.

Underwater cables are no joke either, especially if you're building a network of sea cables. Making watertight is not cheap.

And there is the question of doing high power electricity under seawater. I'm not an engineer in that field, that I think it is going to being a whole lot of new headaches.
And there's zero redundancy. If 1 of those piston seals or valves fail, the whole train is at risk for catastrophic failure.

The tricky bit is when you have multiple interacting systems which see different combinations of those sign errors: it makes it a lot more important to know where all the sign flips should actually be. For example, it's quite easy to make a PID controller where the D term is actually the opposite sign to the others.
I feel like this is location dependent. My wife and I are in our mid 30s with two kids (13 and 9). Most of our friends are in roughly the same situation. I’m the oldest of 6 (by quite a few years) and only the youngest (age 21) of my siblings is childless. My kids have 9 first cousins so far. But we all live in rural parts of eastern Canada. I can honestly say, I don’t know many couples without kids. However, being a family with kids attracts families with kids. So it’s hard to say.
Fiat currency is an excellent mechanism for stealing wealth from a population without them realising (well without them realising who took it at least). Each time they create credit by increasing the money supply with new money, they don't create value, they simply dilute the value of the money supply across more monetary units. The value in the newly printed "credit" comes from the existing money. That's why prices go up endlessly. It's not the value of things we buy increasing, but the value in our money leaking away into the money they are creating. The reality is that value of most consumables (food, electronics, cars, toothbrushes etc) is going down in value year on year by ~5% (due to efficiencies in production, automation etc) but by increasing the money supply by ~7% each year (doubling it per decade!), we actually see prices increase by ~2% average (CPI). They are essentially creaming off all the efficiency gains made by the people over the decades and then taking some more just because...they can.
Meanwhile people are accusing the shops of being greedy, and employers accuse employees of being greedy for wanting a pay rise that doesn't even cover half of the pay cut they are effectively getting each year.

It also distorts other fundamental signals like GDP. Devaluing the unit of account by printing money makes the GDP figures go up because you're measuring it with something that's going down in value. Looking at the USA and accounting for money supply increase, it has had falling GDP for decades. You think your savings are going up, but they are going down etc. etc.

Money is proof of work, or it should be. To create it should take as much work as it's worth (this is true for both gold and bitcoin). In reality, the fiat we currently use is proof of work for the population, while the bankers have a free money spigot. They can pour trillions of money out of nowhere with a few keystrokes and then charge interest on it for decades to come, as if it was their own money.. It gives them undeserved, unlimited power. And what's the best way for them to get more free money? Generate more loans/credit. And what's the most effective way to do that? Trigger wars and, if possible, fund both sides.
Over 30 years ago I found myself in a similar situation. I took a Dale Carnegie sales training course to learn selling techniques. I was the only one in the room with no "product" to sell.

Here’s the catch, as you scale up, more and more users could get caught in the edge case. Remember why we build systems — for end users to use. It is our job as engineers/technologists to solve them.

This is where trade-offs in engineering and product are important.

Is the edge case safety critical or poses a safety risk? If so, it definitely should be considered and handled.

Does the edge case block a critical user flow (eg. purchase/checkout step)? If so, it should probably be considered.

Does the edge case result in some non-critical piece of UX having the wrong padding in some lesser trodden user flow? Possibly acceptable.

Sure, but the point of the HBS paper isn't to paint a realistic picture. It's to imagine a hypothetical world where OSS doesn't exist, in order to derive a monetary value of its worth.

I agree with this article that the actual values might not be realistic, but it's a good thought exercise that highlights the importance of something most of us take for granted. Arguing about the methodology used to arrive at those numbers is missing the point, IMO.

You're getting into the weeds and will get different answers based on semantics, here.

A FPGA emulation isn't inherently better than a CPU-based emulation of any given chip; it's not more authentic because it still lacks the particular quirks of any old CPU that are associated with the way the hardware was laid out, path lengths, imperfections etc.

I'm glad it's introducing FPGA programming to a wider audience because FPGAs are probably going to become more important going forward - and are probably going to be what keeps Intel alive - but it doesn't make the emulator inherently better.
The issue is with the title, not the article.

In the article, they refer repeatedly to the "Hong Kong stock exchange", not the "Shanghai stock exchange" or the "Chinese stock market".

Could it be that the article was originally titled "as much as the whole Hong Kong stock market", but the reviewer worried it implied that Hong Kong is independent from China; so they changed it to a `safer` but less accurate title?
The question I guess is: are UCI-governed events not using "NDD" bikes only because of regulations on what shape can be used, or is triathlon special in that it favors aerodynamics more than other events?

That is: if regulation was dropped, would pro cycling be filled with weird looking CF monocoque designs, or is the traditional design still optimal for some use cases (e.g. for weight and events with team ridning and lots of climbing)?

TLDR/advertorial halfway through: “But we at Synaptics think that we’ve met those challenges.”
A kettle uses ~1.5KW, a geyser ~2KW, an oven ~5KW, a stove about ~3KW. These are fairly high estimates I got from some quick googling. If you add these all up, and account for some more appliances (HVAC, fridge/freezer etc.), I think it is safe to estimate that a household less than 20KW at peak, even though it is a fairly high estimate.

So going backwards from there, 1.2MW = 1200KW and 1200KW / 20KW = 60 households at peak usage. Which is a very conservative estimate.

For future reference I will use 1MW = 50 households as a conservative rule of thumb. Maybe 100 households per MW is closer to reality, but that feels fairly lenient to me.
But intuitively efficiency per passenger should only be the binding metric if you are not capacity constrained. ie it may be economical to fly four-engine planes with nearly twice the number of passengers, than not meeting the demand on a route because it is saturated.
Yes, I noticed that too but I figured better a bad translation than none at all, this guy is amazing.
I was thinking at the team/org level. Edge cases are left out after some discussion on how much impact they have and how they'll have to be handled, so there is a conscious choice to not deal with cases that are rare but will happen and require intervention (cases that can just be ignored or worked around out of the system are a different thing, and unknown/unplanned edge cases are just bugs).

If there is specific finger pointing needed IMHO it would land either on the manager or the product owner for miscalculating the impact of that decision.

PS: To your point on "weird" code, imagine a code that just asserts for some conditions with a "if these conditions are true call XXXX team for help" message on it. That's how I'm representing an unhandled edge case.

> So why bring Trump into a Law 101 topic?

Because it was a recent, high profile example of a search warrant being executed against a residence prior to the indictment of a suspect. Though I should have anticipated that some people would struggle to decouple their strong feelings about the former president from the specific point I was trying to make.

> A mishandling-classified-documents investigation does not require a higher level of scrutiny than a domestic terrorism investigation.

It’s not about the “level of scrutiny” so much as the risk to the officers executing the search. If you’re investigating people for committing organized and premeditated acts of violence motivated by opposition to law enforcement, it’s reasonable to presume that those suspects pose a high level of danger to law enforcement.
One practical difference is that software emulation almost always runs under an operating system and all sorts of cruft which can add latency and jitter. An FPGA just does the one thing.

We actually need to talk about lists. The single reason why Lisp uses parentheses is the list notation -> programs are actually lists, not just text.

The same code which runs

CL-USER 10 > (let* ((foo 10)
(bar (+ foo 32)))
(* foo bar))
420

becomes data, when quoted:

CL-USER 11 > (quote
(let* ((foo 10)
(bar (+ foo 32)))
(* foo bar)))
(LET* ((FOO 10) (BAR (+ FOO 32))) (* FOO BAR))

A typical Lisp function can then substitute all * symbols to + symbols:

CL-USER 12 > (subst '+ '* '(LET* ((FOO 10) (BAR (+ FOO 32))) (* FOO BAR)))
(LET* ((FOO 10) (BAR (+ FOO 32))) (+ FOO BAR))

EVAL can execute lists:

CL-USER 13 > (eval (subst '+ '* '(LET* ((FOO 10) (BAR (+ FOO 32))) (* FOO BAR))))
52

Thus the single main feature is that Lisp itself is an application of the List Processor. This feature then is user visible in read eval print loops, debuggers, inspectors, code formatters, source interpreters, code generators (-> macros), embedded languages, ... So Lisp developers loved it, because one would not need translators between user facing (infix) syntax and internal data structures (ASTs, ...). Thus early attempts for other syntax variants failed, because this duality between data and code has some kind of elegance. Something which for example impressed Alan Kay (of OOP / Smalltalk / Dynabook / ... fame), when he understood that something like a Lisp evaluator can be written in a few lines of Lisp code, processing lists, which is code. -> https://www.quora.com/What-did-Alan-Kay-mean-by-Lisp-is-the-...

I think you're assuming renewable means infinite.

> - nuclear

Nuclear isn't renewable, but there's a huge amount of it and it doens't have the same problems.

> (and so the sun) is not renewable:

The energy we get from it is. It's not a fixed resource that we're depleting. When we burn all the coal, it's gone. Tomorrow there will be more sunlight. We're not cutting chunks off of the sun to get energy for solar.

> - fossil fuel is renewable... on a geological timescale,

Only some of them, and only if we change the definition of renewable. Coal is there because there weren't fungi that could break down lignin at the time.

> Imagine you wrap the Earth inside a sphere of perfectly efficient solar panels, that would be energetically troublesome! Every bit of solar panel we lay removes a bit of that overall energy flux; the question is then how much can we afford without detrimental impact.

We could probably benefit significantly with reducing the energy flux right now.

Story mentions "250 miles" but doesn't put any numbers to feedback latency.

I expect that's the vital number: Surgery shouldn't be as vulnerable to lag as twitch games; but the longer that delay is, the harder it will be doing anything.
> Replacing traditional speakers with piezoelectric transducers will allow devices to be much thinner.

I appreciate the fact that this technology could make mobile devices more durable because it has less moving parts, but I don't feel going any thinner than what's currently available is desirable from an ergonomics perspective. I just don't feel as comfortable holding a phone that's 7mm thick, or less.

And I certainly don't think it's worth the risk of it folding in my pocket.
When you look at typical FGPA emulator source code, it often looks pretty close to software emulator code ported to VHDL/Verilog instead of an attempt to re-create the original reverse-engineered 'transistor-level design' which would automatically reproduce any 'undocumented behaviour' of the original chip (like http://www.visual6502.org/JSSim/index.html)

As such, an FGPA emulator isn't necessarily any closer to the original hardware behaviour than a software emulator. I guess the main advantage of FGPA is better performance on lower cost hardware.

> Would you have been able to do it without finding someone who knew already

Yes. Encyclopedias of the day had a lot of this sort of information and so did DIY books.

I have a copy of Everything Within from about 1930 that has chapters on radio. In addition it tells you how to make a rectifier from scratch using just copper sheets and various chemicals.

Many people think an FPGA is automatically accurate emulation because it's "hardware" and the original console is "hardware".

But the FPGAs are based on C software emulators because that's where all the knowledge in the world of how to emulate the original system is kept. You can't translate original hardware to Verilog and skip the figuring out how it works process.
