If you're retired and don't need to do the Webrogrammer grind of employable skills, that's a great time to learn advanced/alternative topics of programming like this.

(But if you instead want a paying second career, you probably want to either focus on Web or phone app development instead of this, or have a personal connection to get a job in some less-common area of software development. The Little Typer probably won't help you with that.)

I suspect that the book will do a good job of explaining its topic, from scratch. Here's how to install the software that the book uses:

I agree with you about the causes of the current fiscal situation. If you look at videos from 2008, Trump was criticizing the Fed’s zero interest rate policy saying it would cause a problem down the line. Then what did he do once in office? Sent everyone checks with his name on them. That’s the exact sort of thing politicians do in Bangladesh. My mom, who never even considered voting for Romney or McCain or Bush, is hoping Trump beats Harris. The GOP is doing what it needs to adapt to cultural change, just as it did with Reagan, who flipped Catholics by declaring a truce with the new deal.
Nearly any uses for flexible electronics would also be satisfied by sufficiently small electronics such that lack of flexibility doesn't matter.

Eg. rather than having every pixel in your flexible screen be flexible, you make each pixel rigid and have the joints between pixels flexible.

In this case, this design is based on SERV, which uses ~2100 gate equivalents, which in a recent tech node would be 40 um^2. That means you could fit a 10x10 grid of these in a single pixel on an iphone screen.

I really can't think of a use case where a region 1/100th of an iphone screen pixel being rigid would be a problem.
I get this argument from some ppl and here's my response: ham people are those who have the patience and taken the time to learn and follow a set of rules and physics. They are generally more responsible then internet randos. To an extent, ham radio is like early internet which required will and effort to piece together. It had a value and a meaning so you didn't squandor it.
You could probably engineer some palatable food items with algea and mushrooms. I would put my money on fungus as a food source.
Financiers don't just look at current costs, either. They look at the trajectory of costs. A nuclear power plant constructed today will be competing against renewable and storage technologies a half century or more in the future. It's a poor bet that those technologies won't be even cheaper than today, when they've been improving by an order of magnitude in cost each decade.

Any technology that predicates its economics on paying out over 40+ years doesn't make sense in an environment of rapid technoeconomic change. Renewables have accelerated the rate of change in the electrical power industry to a rate not seen since the early 20th century.
Have we ever thought about building a nuclear reactor underground before? Seems a little insane, but I'm trying to think through the "why" part.

It would be awfully convenient if the way you "store" the nuclear waste is to just leave it in the reactor underground and then build another one!

Immediate problem that comes to mind: Groundwater contamination.

Also it being a pain to build (probably?).

> PS: Most complaints about “slow Internet” are due to poor WiFi quality.

The exception to this is Deutsche Telekom. They demand atrocious pricing for peering and only have very limited peering at DE-CIX and BCIX - 20 Gbit/s at DE-CIX [1], compared to the 2x600 Gbit/s that, say, Vodafone has.

The result is massive complaints about peering with virtually anyone, even the big dog Cloudflare [2].

I recommend every fellow German to subscribe with a regional provider - in Bavaria for example, book a M-net connection. The last mile will be handled by Telekom who are subcontracted by M-net or whomever else you choose, but there's government-regulated exchange points so you bypass Telekom's shitty peering.

You don't need to understand how useState works if you're writing a page with a button that increments a number when pressed, from a beginner's tutorial.

As soon as you work on any remotely complex codebase, you will run into problems that require a decent mental model of the underlying "magic" to properly understand and solve. "Building sophisticated applications while understanding very little of the underlying model" is how you end up with gigantic piles of unmaintainable spaghetti code full of awful hacks, which seems to be the standard for React applications.

Lessons from MKBHD's App Brouhaha
Sometimes I don't understand this argument because theres nobody forcing you to always be on the latest version of a framework. You could have just stayed on the version of Vue you were using without issues. Unless theres some compelling reason you could use it into the end of time and be just fine.

Thats not to say that maybe for your use case you could have not used it in the first place or that removing the dependency was a bad idea - just that if you do like Vue there doesn't seem to be anything forcing you to always be on the latest version.
Overbooking used to be called the "contention ratio" back in my day when I was working with Nortel CVX 1800 modem racks (and before that too with older, crappier, less dense racks running off E1s or even ISDN).

A full rack of 1000 modems at 56kbps means 7Mbps bandwidth needed to feed the box. We had ~20 racks, so we'd need (in theory), 140Mbps up to the internet to service them all at a 1:1 contention ratio. In truth, we had ~35Mbps - a very generous 4:1 contention ratio.

Why does it work? Well, when you're browsing the web, you load a page (and use bandwidth), and then you read it and don't use bandwidth.

For every second of download, you probably have 30+ seconds of idle bandwidth while you're reading those emails or web pages or whatever - and yes, one manager was pushing us to get to 30:1 contention, which was industry norm at the time - so this actually works fine. One colleague who had worked at a major competitor told us they regularly pushed to 100:1 and no customer seemed to care. We actually benchmarked them (and a bunch of other ISPs), and yeah, was a little slow at peak, but actually not awful most of the time.

The problems started to come when people wanted to max out their connection more because of an evolution of applications, technology and expectations (in short DSL, the rise of P2P services and people "being online" more was a triply whammy), and so more customers wanted to use every bit of bandwidth every second, all day, every day. In the UK, even the BBC was being asked to do something because the launch of iPlayer absolutely crucified a lot of ISPs.

I was out of the game by then, but approaches seemed to include citing breach of acceptable use policies (very unpopular), blocking certain services (one of the reasons why the major ISPs block TPB in the UK), or - in at least one case I heard about - traffic shaping those "greedy" customers until they went away. If you throttle someone who is paying for 10Mbps down to 1Mbps, because they've been taking all 10Mbps 24x7 for the last three months, they'll get frustrated and leave your service with the only real cost being a bad online review you can blame on backhaul network/bad copper/bad modem, and which is drowned out by other "normal" users claiming you're a great ISP. And yes, I do know of at least one ISP who did this regularly - a former staffer told me a few years after he left.
So, what's the recommended Scheme implementation to "get things done", and not only for learning CS stuffs?

For example, now our backend system is mostly implemented in Go (some with Fiber, some with Echo). The rest are pretty common: Postgres, Mongo, Firebase etc.

Perhaps Gambit? BTW, I have nothing against experimentation. Not everything have to do with practical purpose on mind. That's why I'm also tinkering with Haskell & Ocaml :D
Everyone who has the capability to land this on the moon is a NASA contractor or a competing space agency. And I don't know how congress would feel about selling this to Roskosmos, the Chinese CNSA or Indian ISRO. Maybe ESA.

Of course somebody else could buy it and pay somebody to put it on the moon. But that seems unlikely given the provision that findings have to be shared. For companies that sell moon landings it's good marketing, for anyone else there wouldn't be much upside
> Each Flex-RV microprocessor has a 17.5 square millimeter core and roughly 12,600 logic gates. The research team found Flex-RV could run as fast as 60 kilohertz while consuming less than 6 milliwatts of power.

This is pretty bad from a power efficiency perspective. KHz speed silicon microcontrollers are closer to ~dozens of microwatts, about two decades of magnitude less power than this flex-circuit.

Furthermore, small silicon dies can be placed into flexPCBs. I'm sure a flexchip has more flexibility than a solid silicon die on a flex board but there's a question of how much flex is actually needed in products?

---------

Still, I recognize that a fully functional CPU on this process is a major achievement. I'm just trying to think of a commercial application, that's all.

The author is right that we rely on metrics too much. But he's biased against capitalism and his proposed cure is more socialism. What's actually lacking is wisdom and integrity.
> The current socio-economic environment, including rapid digitization of information and processes, the rise of machine learning (ML), and ubiquitous access to the Internet, amplifies the need for human-human and human-machine interactions that are transparent, dependable, resilient, and operate at a global scale—without a single point of failure. This might ring a bell; the concept of distributed ledger technologies (DLT), or blockchain, refers to systems implementing these properties.

I don't understand what sort of people can write rubbish like this. We need human-human interactions that are transparent, dependable, resilient, and global; and therefore blockchain? What are the authors smoking?

None of this requires the specific (and pernicious) distinguishing feature of blockchain: permissionlessness (enabling the wanton abandonment of the rule of law we see in that space in practice). Good old 1990's distributed computing technology (permissioned!) allows for transparent, dependable, resilient, and global interactions (machine to machine though; I have no clue how the authors interact with other humans. Presumably with WhatsApp or iMessage, which are neither transparent nor without a single point of failure, but are just fine.)

Submariners would like a word.
This is true, but different than the maritime platforms I was talking about. The ones that tend to focus on reliability-centered optimization are platforms used for drilling, not transport. Even then, you will see instances where they decide to optimize for cost/schedule (eg Deepwater Horizon). IMO, that is a company-cultural issue.

Btw- reliability optimization doesn’t necessarily mean it is optimized to not fail. They are optimized to fail within some predetermined risk level. What that risk level should be is an entirely different discussion.

> having just switched over from CMS (!)

This is really interesting. CMS was removed in Java 14 after being replaced by G1GC in Java 9. They were probably running an antiquated Java 8 or 11 runtime. So that means that in 2022 they were either running a 4 year old Java 11 runtime or an 8 year old Java 8 runtime. They were really leaving a lot of performance on the table.

And people don’t bend to my every whim immediately or live exactly like me so I want to be in total control of the 50 miles around me.”

It's actually quite clever from the part of the scientist.

The incentive would be money, maybe the pay for doing this test was not good enough.

Or maybe the scientist was motivated by thirst of discovering something good for humanity like cure for cancer and didn't want to get distracted by other things. Funding is also needed but angel bones are clearly impossibility. Why even spend time on disproving that? But if she had engaged in discussion with people clearly believing in this nonsense it would have taken too much time. Saying, the tests are inconclusive lets her be distanced from all this and allow people to leave her alone, mostly that the groups will continue their disputes among themselves.

It's more that a room/wing/building/whatever is built with a certain capacity, while power and heat density keeps increasing. Most buildings can't "just add cooling for 5kW". Newer data centers should already be built with that lesson in mind, for example with a lot of extra air moving capacity etc planned in, but that's been the struggle for a while now.
I wonder what guarantees can be made wrt resource consumption. I suppose that'd reasonable to assume that in most (all?) cases an update is cheaper then recompute in terms of cpu cycles, but what about ram? Intuitively it seems like there must be cases that would force you to store unbounded amount of data indefinitely in ram.
So there are people working on that [1]. It's basically geothermal where the heat is generated by a nuclear reactor. If anything goes wrong, you just bury it. If it's geologically stable, not near a water table and a mile deep, then there's a certain logic to that.

Ah, interesting. That sort of split voting is indeed very bad luck, potentially a config-specific issue, or just a cluster that's seeing a catastrophic partition failure between every node.

In canonical Raft assuming no partition failures, this could only happen if every node's election timeout triggered at roughly the same time and they all become candidates simultaneously. For this state to persist (assuming short election timeouts and short heartbeat intervals), you have to get _really_ unlucky.

In terms of probabilistic likelihood though, this is about as likely as the live-lock issue in Paxos in which multiple proposals with differing proposal ids are made at the same time. You'd seem a similar delay in consensus in that scenario as well. Obviously MultiPaxos handles this with a separate leadership algorithm which makes that outcome much less likely, but the same types of strategies common in those systems to mitigate contention issues can be used in Raft as well (randomized backoffs for example).

This could probably be extended to more than two images. Don't know how far you can push it before the images look too contrived to be interesting.

In thinking how I would start, I imagined starting with only one kind of shape, except filling/flattening out the edges/corners. Then come up with a dual picture that depends on 2 arrangements of the pieces. Finally adjust the edges of the piece shapes without breaking the 2 selected arrangements but allowing all the other possible arrangements to collapse down.

It's like making a repeating/tiling shape where you start with a blank tiled plane then start drawing anywhere, all the repeated places also get drawn in, and you keep drawing/undoing until you like what you see. i.e. 'maintain the constraint from the beginning'. The tricky bit is in the drawing/painting. I imagine the same could be done with this jigsaw, blank the pieces, show both arranged blanks, and let someone paint on the pieces updating both as you go. When you like what you see, you're done.
I don't think it's possible for the younger generation to appreciate how much better it is for boys in STEM today than it used to be.

Missing in this discussion is what it meant to be a boy interested in STEM socially.

It's cool to be an engineer today. It pays very well, it's easy to make friends, find a mate, etc.

Those of us who grew up as nerdy kids in the 1980s dealt with the kind of bullying and social ostracism that future generations cannot even imagine.

Are boys being downplayed in favor of girls for advancement opportunities? Maybe. But you still have it MUCH MUCH better in a holistic sense than we did, to a degree you'll never know.

It is not a choice in many situations. For a large company that has many different teams that own many different parts of a product, even though teams adhere to the same "UI standards", things get complicated quickly. For example, CSS classes that have name conflict can cause UI to break (which happens more often than you think, and strictly adhering to naming rules is just hard for humans). That's just one example. Custom elements with shadow DOM is a simple and straightforward solution to this, and it makes sense -- JavaScript code are scoped to modules and use imports/exports to define interfaces, and it is just natural to do that for UI instead of putting every class that other people don't care about in the global CSS space.

Griefbots and the Perils of Digital Immortality
What happens when old versions stop receiving security updates?
It's an effect that exists, but the examples aren't accurate.

An overemphasis on grades isn't from wanting to educate the population; obesity isn't from prioritizing nutrient-rich food; and increased inequality isn't from wanting to distribute resources based on the needs of society.

Living a well-lived life through culture, cooking, or exercise doesn't make you more susceptible to sensationalism, addiction, or gambling. It's a lack of stimulus that makes you reach for those things.

You can argue that academia enables rankings, industrial food production enables producing empty calories, and economic development enables greater inequality. But that isn't causation.

It also isn't a side effect when significant resources specifically go into promoting education as a private matter best used to educate the elite, that businesses aren't responsible for the externalities they cause, and that resources should be privately controlled.

In many ways, it is far easier to have more public education, heavily tax substances like sugar, and redistribute wealth than it is to do anything else. That just isn't the goal. It used to be hard to get a good education, good food, and a good standard of living. And it still is. For the same reasons.
