This essays comes across as a kind of trap that is oft seen regarding people who support changing a system:

1. If you benefit from the system, you are accused of being an idiot and/or hypocrite to support changing the system.

2. If you do not benefit from the system, you are accused of sour grapes or an outsider who doesn't know what they are talking about.

The first is the criticism of various socialists such as millionaire Bernie Sanders, millionaire and model Emily Ratajkowski (who supports more egalitarian economic systems as well as various gender issues surrounding modelling and taking female intellectuals seriously), and various other actors and musicians.

It then comes to no surprise that the essay is hosted on a site devoted to right wing^W^Wconvervative views.
The implementation requires that you have at least one authorized substitute server advertising the same hash.

In simplified terms, if ci.guix.gnu.org advertises a substitute for /gnu/store/abc123-foo, with the checksum "xyz789" (and the cryptographic signature of that advertisement checks out), your daemon can safely download that file over P2P.
Aussies... Goodness.
I think it may be legal, since saying it qualifies as a disclaimer. Basically the default is 24m (EU) or 12m (US), but it should be legal to explicitly state another term for warranty.

Some shops have down to 1 week of warranty, some (e.g. wholesale items) may state to accept no returns, etc.

I mean that not having children is denying unborn people from the lives that they might have for no better reason that this might be easier for someone else unborn. This line of thinking leads to a suicide as a logical step which is rather bad extreme.
> A key feature of neural networks is that the outputs are a nonlinear function of the inputs. However, steering a 2D car is simple enough that a linear function is more than sufficient, and neural networks are unnecessary.

This depends entirely on the definition of 'steering a 2D car'. In the model used, throttle is simply proportional to the distance to the nearest wall in front of the car. This means the agent will never accelerate coming out of a corner, because it can't know it has the headroom to steer away from the wall as it's coming out.

Similarly, the model for steering inherently steers the car towards the middle of the track. I would expect the car to wobble from left to right if the road's edges are ragged, make up its own corners if the track edges describe a 'fake' turn on a straight bit, and the car would likely crash if it were to encounter a Y junction or a pit stop. The neural network agents showed smarter behavior here because it is able to capture more complex cross-dependence between different inputs.

On the topic of junctions, if the track were to include them, perhaps it'd be nice if the car chose the quickest route to optimize for lap times. But maybe that stretches the problem statement too much.

> Instead of doing anything fancy, my program generates the coefficients at random to explore the space. If I wanted to generate a good driver for a course, I’d run a few thousand of these and pick the coefficients that complete the course in the shortest time.

In theory this is more random and less efficient than an evolutionary algorithm, which searches the problem space in a structured way. If the author really wanted to hammer the point home, a least squares method to one-shot the coefficients would be more convincing.

All in all, the author doesn't make any hard claims that are false. But I would nuance the point of "neural networks are unnecessary" to "simpler models will do for simpler objectives".

> With the prevalence of "smart" appliances and ever coming IOT

Someone was recently complaining that their Arduino project was gobbling up mobile data. They had used an Ethernet shield coupled to some 4G network something.

After a bit of back and forth the culprit was found: it was sending one byte packets.

The standard Arduino is extremely memory limited, so a typical trick is to use the Flash memory to store string constants, and then use those when writing to devices etc. The library code has some nice wrappers which makes things like sending a Flash string constant to some output stream like a serial port or say Ethernet shield fairly seamless.

However for reasons[1], the Flash variant of the "send constant string" call does this by reading and sending one character at a time. And the Ethernet library (memory constrained) or Shield did no extra buffering, so it sent minimum one packet per call...

[1]: IIRC the Arduino Flash is 16 bit and the characters in the string are stored zero-expanded, so it can just memcpy but has to strip away the top byte.

In my understanding AI is an even broader term and means "any solution that imitates intelligent behavior". E.g. expert systems which are pretty much a bunch of if-then rules are also considered AI.
You're confusing requirements with implementation. Sure, you don't have to douse your motherboard in epoxy, just find an equivalent implementation to fulfill the same requirements* . Still damn difficult.

> So, people burn hydrocarbons for energy. How do you expect to capture the carbon piece into a stable compound that can be buried without expending more energy? Please draw this chemical reaction out, along with energy balances and how endothermic it is.

If you read the article, you'd see:

> Nowadays, Industrial production accounts for one-quarter of CO2 emissions from energy and industrial processes. With the demand for cement, steel and chemicals remaining strong to support a growing and increasingly urbanised global population, the future production of these materials will have to be more efficient and emit much less CO2 if governments want to meet their climate goals.

In other words, this technology is not targeted at capturing carbon that is burned for energy.
> i average 48mpg on the previous gen Prius Plugin

Man, I did 46 mpg with a VW Passat in 2018 (UK gallons tho)... Stats like these are disappointing.
Ubiquity definitely also has a lot of issues. Unstable firmware's, non-responsive support on their forums, deprecating working products... Like you can't self host their DVR software, but the newest versions don't run on older hardware so you have to buy a new hardware to get new software.

Also their product lines Edge and Unifi don't work together, so you can't manage an EdgeRouter with Unifi or vice versa, for which I don't think there is a technical reason, just commercial.

Hardware wise they also have made strange choices regarding PoE, don't assume your Unifi PoE switch will work with your Unifi PoE device (really double check the versions, voltages, passive/active)

So lots to complain, though I think it is still the most accessible pro-sumer networking stuff.
This is pretty cool, since there is no word size you can chose to compute numbers of any size you want when you write the program. It's pretty fitting for a calculator application.

> Cynically, neural networks are easier as you don't really have to think about your model. Give some examples with some classes and you're done. Or give examples of one class and let the neural net generate new ones. Doing away with the abstraction beforehand is an enticing prospect.

If you're trying to solve a well understood business problem sure but my issue with this is that you pigeonhole yourself and your solution. I'm much more interested in understanding the model than doing the implementation because that allows you to build on top of what you get out of the box in a framework for example. It's like learning React before learning Javascript. It might be a good short term solution but long term it certainly isn't.
I question the legitimacy of a comment that tries to criticize an article for using a picture of a nuclear power plant when that picture is in fact of a coal-fired plant [1], something you'd easily see if you clicked on the picture before posting snark.

I keep reading the description but I'm really struggling to come up with a common use case for this.

A number of ISPs in the UK (I think both BT and Sky) used to do something similar (possibly still do), where you would add a special network to your router that was only open to other people who also added the network to theirs, so you could use each others when out and about. It was all tunnelled and secure. It was genuinly useful in the days before 4G mobile and widespread wifi in shops and cafes, I used it a lot.

With this I just don't see what devices would be using it. It isn't something you can just piggyback on to check your email. It feels like this is preperation for some new device or service.

Or am I underestimating the number of people who want to put an Alexa device somewhere that they don't have a network, but which is close to someone elses network?
Can you explain why an end-user would need this in practice?
> The idea that you could do this belies total ignorance of chemistry, fossil fuel genesis and the laws of thermodynamics. Life actually does a pretty good job of turning CO2 into dirt which gets buried

Coal: about 350m years ago we didn't have trees because lignin had not evolved. Then we got lignin, and trees, and when trees died and fell they just stayed there because we didn't have fungus that could decompose them. Then (about 50m years later) fungus evolved that could decompose trees. All coal exists in that 300m to 350m old seam.

Life takes CO2, turns it into carbon, which is then released when those plants die and decompose.

Forests are a buffer, not a sink.

If your software is compromised it can already read or write it whatever it wants off of an IronKey, or fire off a passphrase change request behind the scenes and replace your passphrase with an insecure one to render the physical device insecure, at which point it is equivalent to a $27 USB stick.

Perhaps in an enterprise setting with physical controls and air gaps you might be able to have a device require a different admin PIN to change the passphrase, avoiding the latter scenario of data exfiltration, but then the device has to be explicitly designed with this in mind to avoid any other exfiltration channels for the true PIN and I don't think IronKeys claim to do this (I don't even know if they support such a split admin PIN). And besides, you probably have bigger problems if your air gapped computer is compromised anyway.

Really, IronKeys and their ilk cater to corporate and government bureaucracy use cases that have long since been divorced from true trustable security. They are instead a mountain of complexity, and the more complex a system, the less likely it is to be secure.

The thing about software is that you can audit it yourself - it's quite easy to read through the entire source code of a trivial but secure file encryption app and convince yourself that the algorithms match published and industry standard implementations, and that they match test vectors, and that it interoperates with another instance on another machine, or send the files off to someone else to double check. You cannot audit an IronKey yourself.

But yeah, sure, defense in depth is a thing, and if you use an IronKey and software encryption (with different passphrases!) then you probably end up with better security, or at least not worse :-)
Well that depends on your definition of AI. Which isn't well defined. We call AI what we perceive as "magic". Black box algorithms have a higher chance of being perceived that way (e.g. neural nets). When you get some insight into how an algorithm works (easier for transparent box algos, but same holds for black box algorithms), you start to see it less and less as "magic", and, consequently, you're less likely to refer to it as an (artificial) intelligence. Because ultimately, that's what we mean by intelligence -- magic. When we say that something is intelligent, we liken it to ourselves: it evokes a sense of identification. It all comes back to a sense of humans being fundamentally separate from "the other" (computers in this case). If we saw the mathematical models and algorithms as just that, we wouldn't call them AI. Also, if we didn't think of our intelligence as more than the behaviour of our biological computer, we wouldn't be enchanted by the concept of non-biological systems mimicking some of our behaviour.
From working at all, sure, but how big would those rockets have to be?

Rocketry doesn’t exist just because some idealists wanted to go to space. It exists because governments wanted to invent new ways to bomb their enemies. A V-2 allows you to bomb England from continental Europe (and wasn’t even a cost-effective solution for that); nobody was going to build a Saturn V-sized rocket for that use case, and even if they wanted to, it’s not clear that they could get it to work without lots of testing with smaller prototypes.[1] Compounding this issue is that, on this hypothetically larger planet, whatever enemies you’d want to bomb in the first place could also be much farther away! Whereas on Earth it’s not hard to reach any other point on the planet; a little over a decade from the V-2 we had ICBM’s.

[1] By way of analogy, Lofstrom loops are theoretically much more efficient than rockets, but to find out for sure we’d have to build a full scale example, and that would be extremely expensive even if we didn’t run into any unforeseen cost overruns or delays—which we inevitably would because this would be the first time we built anything like this. It would be like ITER except at least ITER has a practical application if it works.
So where's the manual for someone who just arrived in the US explaining that? How am I supposed to know that if someone doesn't tell me?

How is that even a vaguely acceptable response, let alone _expected_ behavior I should anticipate? I cannot even fathom someone spitting in my food in Australia under pretty much any circumstance.

Absolutely ludicrous!
Many options. Drill through the conductive portion of the USB connector itself, which obviously can't be part of the circuit. Put it in a cryogenic freezer to kill the electronics without wiping the static ram. Evesdrop on the USB connection itself which leaks EM radiation like a sieve. User power analysis to extract the key since a device in this form factor is typically not using constant-power components.

That's just off the top of my head.
I do know there's not a single/unique way of installing dependencies, etc. But the IHP docs are enough clear to set up a project and install everything in just a moment. Maybe the Haskell community doesn't have a clear choice, but the people of DI have made that very simple.

It's called an analogy. It was about terminology and jargon. I'll try to be more non-abstract going forward.

To put it into perspective, Kingston offers other sizes down to 4 GB, which cost about one tenth. Depending of your use case and what kind of data you want to store, I think it’s reasonably cheap for the added convenience.

I own a 1 GB IronKey myself (purchased back in 2008 when I worked as an IT contractor for a German telecommunications company). Mine sadly no longer works under current macOS versions but other than that, I remember being quite happy with it.

I would think this so cool if it were a grassroots project or even a plucky little startup.

Why does the jargon matter? It all describes the same stuff.
If that happened then we'd just start using the electricity for something non-essential instead. Humanity is not interested in efficiency for the sake of reducing footprint. Humanity is only interested in more. If anything, fridges using more electricity means less electricity wasted (assuming refrigeration is essential and not a waste).

This pattern seems to be everywhere. Cheaper electricity: more electricity used. Bigger roads: more miles travelled. More efficient engines: bigger, more powerful cars. Plastic recycling: more plastic used. I challenge you to find any improvement in efficiency which has led to a reduced footprint.
Thank you for the insight! I wasn't being dishonest. I was actually unaware that staking rewards were variable based on the amount staked, such that more ETH staked means fewer rewards per ETH staked. It makes sense, guess I just didn't think about it. I might have thoughts on it but I'd need to process first.

There is genuine value in that, a similar operation has been performed using silver & gold for thousands of years. Gold is an almost exactly the same in that respect - energy gets burned on the owners behalf, and they can prove it happened.

The difference that I'm keeping an interested eye on is even if gold mining ceases, the energy required to produce a new gram of gold doesn't really change so a gram of gold still proves as much as it ever did. It isn't so clear yet that Bitcoin proves anything without an active mining network.
