It is a niche that needs filling for sure, but I'm concerned that the code analysis and transformation talent is going to continue in the current path, namely, spread out thinly across many environments, languages, and toolkits. What we need is not only a wonderful tool for static code analysis, generation, and transformation, but also an energetic juggernaut of a foundation to evangelize and drive adoption of it. Otherwise, talent will end up corralled in to the Eclipse SDKs of the world.

Using a graph that shows soaring productivity to argue that soaring productivity isn't happening seems a little counterintuitive to me. But I'm not a prize-winning economist, so perhaps I'm missing something.

The US economy can't be fixed by educating more plumbers. The core problem is that the US has turned itself into a peacetime rationing economy. Essential services - healthcare, education, housing, financial support - are strictly rationed for reasons that are strictly unnecessary and economically destructive for the majority of the population.

The extracted value paid by individuals to the companies that provide and finance these services is effectively a privatised form of tax. It's vastly more onerous than the official tax rate, while providing no true public benefit - and no democratic representation.

More plumbers and electricians won't change this, because they'll still be working in a system where they'll have to charge unaffordably high prices to make a decent personal profit after the "corporate taxes" on health care and education (and personal housing) are paid.

Ultimately it's a political choice to run a starvation economy for most workers, and that won't change unless there's a political shift.

Which badly needs to happen. This is not about automation, and it's not about AI. There's a huge amount of productive work that isn't being done - new infrastructure, maintenance of old infrastructure, childcare, health care, education at all levels, housing, trade and building work, academic research and open-ended no-immediate-return blue sky R&D - because the political economy is biased against that kind of activity rather than for it.
I mean, I think it’s more just that office buildings don’t normally have escalators.

Already a lot of popular brand frames were made in Taiwan.

Also, if enough manufacturing shifted to Taiwan, that itself might prompt a certain "stable genius" to add them to the list of tariff countries. Or China might become aggressive enough toward Taiwan that he would lump them with China in tariffs.
The JVM has state of the art GCs, name another platform that comes close in terms of offering the ability to tune it for throughput or latency as the JVM does, or that comes close in performance (.NET probably is the only contender).

If you don't want memory usage to go up to 400MB, then you can set the maximum memory the JVM can use to less than 400MB. It only makes sense from an efficiency and throughput standpoint to use as much memory available for performance.

JVMs regularly run on GBs or even TBs of heap space in production.

Both Shenandoah and ZGC target lower pause times (at the expense of throughput, naturally). There are commercial offerings like offerings from Azul that target low pause times as well.

> the JVM is probably the worst part about the Java ecosystem

On the contrary, the amount of optimizations that the JVM performs, as well as the monitoring, management, hotswapping, etc capabilities are second to none.

> It's slow

The fact that the JVM tops several charts here says otherwise: https://www.techempower.com/benchmarks/#section=data-r17&hw=...

> (mostly startup performance)

This is already being resolved through GraalVM. See for example https://quarkus.io/

> because the JVM is such a failure.

It only runs the backends of companies like Amazon, Google, FB, EA, LinkedIn, Ebay, Apple, Netflix, and countless others. Not to mention it's being used in high performance spaces like HFT.
good CRT monitors would auto-sync and get the aspect ratio right.
Sounds like it's a decent commuter-ish bike?

You don't see many of those in the US compared to places like Europe or in your case Japan.

Probably because there's less of a market for them in the US.

What the OP is probably thinking of is the crappy bikes you get at supermarkets, where the quality is really not very good, and they're assembled by someone who is not paying attention. Sometimes they try and look like a more expensive bike: front shocks, lots of gears and so on. The commuter bikes in Europe were, on the other hand, built with that in mind - big fenders, more upright position, and fairly rugged if not lightweight construction. You wouldn't mistake them for a bike you'd want to go on a long ride with.

I've read all, and got both interesting points - useful to me angles of view - and certain statements and conclusions from then which I don't agree with.

1) Author says object and data structure are different things basing on stated difference, but doesn't explain why this couldn't be a different point of view on the same thing.

2) When author says "adding a class is easy when you need a new entity, while adding a function is easy when you deal with data structures" he doesn't mention that only "packaging" of code - into switch cases or separate methods - is different. To add Triangle, one still has to add both fields which contain Triangle data and all the methods which work with that data - area, perimeter, center. Similarly, adding data structure "Triangle" also needs all those additions - and only them - but in a different form.

And many derivations from this perceived difference are, um, questionable.

Yet I like author's explanation of impedance mismatch. True, data storage has to satisfy many needs (roughly, we don't want to copy data - normalization), while logic may focus on specific goal at hand.

Accidental cat filter derails political press conference
Better alternatives for now, Im not sure to be honest. I just feel it is much easier or more tempting to go fast on a scooter. Since one doesn’t have to pedal and put in physical effort, it is tempting to always go fast (or faster) as opposed to naturally go with the flow. And it doesn’t help that electric scooters drain by distance when speed is variable or the difference is insignificant. Why would one wait behind a cyclist when they can quickly accelerate and pass. At least some would be tempted. This creates some kind of traffic mismatch and more collisions are likely, I think. Im sure some rules and common sense would eventually ensue. Learning from mistakes. Or maybe a top speed could level the traffic off. Or maybe even some sort of light “licence”. I hear that in Germany one is required for cyclists and thats a good way to ensure some responsibility or better aquitance with the rules.

Maybe I’m wrong. I am not certain of anything but electric scooters seem to me like a good and clean way of transportation. I feel that I’d like to see fewer cars as well. I imagine cleaner air, etc. We’d be all better off with all kinds of development in light and efficient transportation. We seem to be stuck with large and energy inneficient stuck in the past transportation. Seems inevitable a change will come along.
A lot of assertions here about waste management and relative harmlessness of landfills.

Do you have experience or exposure to the recycling, waste management and landfill industry that you can share? Have you spoken to any landfill managers, have some idea of the volume of plastic waste and the landfill industry? Or is this just speaking from the gut?

Most articles have experts[1] and researchers[2] expressing grave concern about waste and microplastics from landfills seeping into the environment and polluting animal ecosystems and even our own water and food supply that would give anyone cause for concern. Positioning that concern as 'negative emotional reactions' without providing any science or evidence about why it is so seems unscientific in the realm of wishful thinking.

Huawei says US ban will cost it $30B in lost revenue
This is actually weird to me. It seemed like it should be possible to stamp out bicycle frames like a car, so I researched it. Such a bike does exist, but is extremely expensive, which seems to defeat the purpose. Is it really not possible to streamline the manufacturing beyond welded tubes?
I don’t think I’ve ever been in an office building with escalators. I think this is more just a result of them taking a shopping center, which usually has escalators, and turning it into an office, which doesn’t. They’re not really a practical way to get around; unless you have a rigid “stand to one side” rule (as on the London Underground) they’re slower than stairs.

> I got started in QBASIC and, for all the damage it may have caused, I'm doing pretty OK today

Dijkstra wrote that quote about a very different flavor of BASIC: only line numbers, flow control was only possible with GOTO and a limited version of FOR/NEXT, IF was limited to a single line of code (which 99% was just a GOTO or GOSUB), subroutines were made using GOSUB/RETURN, etc, essentially it was a glorified assembler with an expression generator.

What he was championing instead (at the time) was structured programming in the style of Algol and QBASIC, with its subroutines, control structures, functions, lack of line numbers (well, they were optional for backwards compatibility with GW-BASIC, but i do not think it got much use) etc, is way closer to the style of programming used in Algol than to the style used in the BASIC that he was talking about.
They use a different TCP/IP stack which implemented SACK without introducing this bug.

It's a Linux-specific implementation defect, not an intrinsic problem with the TCP SACK wire protocol or spec.
Camera+ and its VolumeSnap feature, f.lux and the Night Shift feature, Finder for locating your Air Pods, Coolpixel and screen recording. All of these apps offered features that were later integrated into iOS or other Apple offerings. Apple went so far as to send a demand letter to the f.lux devs demanding they stop offering the app for sideloading.
When the internet was young and I was wide eyed optimistic I thought reviews and ratings would solve this problem. It didn't. Then amazon came along and promised a similar panacea, user ratings... but again it didn't quite happen.

((Imagine twitter posts being flagged "This person has no qualifications and has failed a basic maths exam")) -- idea - online exams with my results cryptographically signed.

Block-chain seemed to offer some sort of solution. Maybe if we had trusted manufacturers of components, then these components could be tracked (along with pollution, carbon miles, labour policies, etc) all logged in the block chain.

I just really think the guy is an idiot.

I don't watch CNN and don't know Lemon. But here's a possible alternative explanation (hardly a defense):

Wikipedia says he graduated with a degree in broadcast journalism. He probably didn't pay much attention to science in high school, and almost certainly wasn't required to take any science classes in college.

So, he might not even understand science as simple as F=ma. In his defense I'd bet that if you surveyed the adult population, the majority couldn't tell you what F=ma means.

The above is a long way of saying that most journalists aren't literate in science. And, we know that black holes are "sexy". Many books have been written about them. Many movies made that feature them as key plot points.

So, why not ask about black holes as a possibility? It's as plausible an explanation as whatever it was that happened to that airplane in the Lost TV series of about 10 years ago.

Having said all that, yeah, the guy is probably an idiot. As are quite a few TV journalists.

An entry level bike is not $1200. Thats a mid range high quality bike. If you trips are short you can be totally fine on a $400 road bike. I would just avoid department store bikes that are typically under $300 but are built to look like high end mountain bikes. The suspension on them is totally useless and makes it ride worse than a bike with no suspension.
Well, at the very least electroconvulsive therapy is proven to be effective in psychoses, while lobotomy has no added benefits. ECT will (or so I hope) be replaced in the future but maybe not by something fundamentally different - just more easily palatable.
Calling `join` a relational database is a bit "click-baity". Yes it's a cool command, but you don't get any type of constraints or indexing or atomic updates or any of the important things that people expect from databases.

If the recent tariffs are cited as the main reason for not making things in China, wouldn't things naturally reverse themselves when they are lifted? The tariffs strike me as an artifice that can't be sustained for a very long time- what is their lasting effect that changes the economics of manufacturing things in China?

GraalVM is a way to resolve that: https://quarkus.io/, https://micronaut.io/

You might want to check out C# as well. .NET Core is coming along nicely, and you get to work in a safe environment, with the ability to drop down to pointers if needed, unlike the unsafety that is inherent to C++.

There is also a C# to C++ compiler that the Unity people wrote, worth checking out.

When Uncle Bob discovers subclasses, friends, decorators, and mixins, his mind will be blown.
>Rosling’s “Factfulness” starts with a quiz of 12 questions—ranging from “How many children will there be in 2100?” to “In the last 20 years, the proportion of the world population living in extreme poverty has almost doubled, stabilized or reduced by half?”—to which he then applies his “chimpanzee test”—the likelihood that a random choice is superior to that of humans. Humans always seem to fail the test: even CEOs at the World Economic Forum.

That question about the number of children in 2100 really bothers me for some reason. Sure we can make some pretty reasonable projections, but they will be just that: projections. Even assuming no black swan events, the error bars 80 years from now have got to be enormous. The numbers could be wildly different depending on how bad climate change turns out, and what kinds of technologies we develop. If you're trying to prove that other people are overly pessimistic, it makes more sense to show that they are wrong about currently available data. Otherwise they can just say that your answer to the question is overly optimistic.

It's the same if you ask Taiwan. Their official name is "Republic of China".
Blockchain does not provide any verification of trust, nor can it. It provides verification of number crunching transactions alone, as well as an immutable store of that number crunching. It's actually notoriously poor for trust compared to traditional systems, as there is no way to mediate in the case of fraud once a transaction has occurred.

My friend waited for it to be added, then she put the whole meal, plate and all into a plastic bag and took it away for analysis. The pub got fined and another visit from trading standards.

China executed people responsible for adding an industrial chemical to baby formula [1]. Without debating the merits of capital punishment, I think the issue is the lack of consistency in supple chain management. The only model I could compare to would be Costco, who is pretty good at curating products customers will like (and the quality is usually good IMHO). Trust sells, if you find buyers who value trust.

Which parts of a better quality Giant bike are made in China, anyway?

Maybe they hare having the Giant-branded frames made in China? (I'd be wary of this stuff, if true; a crappy frame can break and kill you.) Or perhaps tires. Kenda tires (Taiwan brand) are likely made in China.

Nothing that you actually hang onto a frame to make a bike that is worth a damn comes from China: cassettes, rings, cranks, hubs, bottom brackets, shifter, brakes, rims, you name it. Only low-end garbage like SunRace cassettes, ProMax brakes and whatnot.

Bike all around the world are typically the same in this way. The "brand" part of the bike goes into the frame, and then what's on it is third-party components from familiar brands.

Some Shimano stuff is made in places like Indonesia. I don't recall having seen a "made in China" stamp on it, though.
I would be very interested in reading those. Please post them here when you do. Cheers.
I gave a talk in China 5 years warning about this. http://tech.qq.com/a/20140527/035512.htm I asked vendors to make changes to their products, such as planned obsolescence so if the manufacturer goes out of business and a device doesn't hear from the mother ship for awhile, all internet connections are killed for good. Also, to set smart defaults so that even when not configured, it won't allow this behavior. There should be a list of more in the article but you'll have to translate to see them.
>What I don’t understand is how providers haven’t a clue which providers are even sending the calls. //

They must know: they're surely not forwarding calls just on the hope that they get paid, they're forwarding calls from providers who are paying them to forward those calls.

They get/got more money if they don't bother to check legitimacy in the short term. The phrase is something like "the chickens are coming home to roost" (ie the result of their bad actions are going to return to them).

I see no reason that my supplier can't add, say, a "0091" code to calls from India, or wherever. Or send a callerid prefix that indicates a spoofed number if it's a domestic call.

I'm no longer using a separate computer from my employer and containers' security always worried me. Using VMs is very cumbersome in my opinion.
I haven't used Docker in years, do you think it's safe enough now to install in your main computer (Linux host)? It's not like I'm going to test malware inside the containers but there's a lot of 3rd-party dependencies living there.
