> Don't forget that most European cities are hundreds of years old, built on river banks, rocks, hills, the complete opposite of most US cities.

What, do you think that North America is a minecraft flatworld? Plenty of American cities are built on variable terrain. The city I live in, Weehawken (Lenape for "rocks bigger than trees"), is bisected by a 300 foot sheer cliff called "The Palisade" because it looks like a castle wall. You have to take an elevator or a long staircase if you want to get uptown.

The only US cities designed from the ground up with cars in mind are in the western desert valleys where nobody could reasonably live until air conditioning was invented: Phoenix, Tucson, Los Angeles. Many German cities were being rebuilt almost from scratch at the same time. Munich, Frankfurt, Hamburg, Dresden, and Berlin all had to be almost completely replaced. Their maps were redrawn with cars in mind, and they managed to stay largely walkable.

Meanwhile, London has roughly the same transit woes as New York. Was London founded after the invention of the car? No! Unlike the planners of Munich and Dresden and Hamburg, London's rebuilders after the war prioritized automobiles over people, and it shows.

New York got its modern street layout in 1807, the same year Napoleon conquered Bohemia, and I'm pretty certain he didn't enter Prague in an open-top car.

Car-centric city planning isn't a natural phenomenon, it is an intentional choice, and it can be undone at any time.

I really loved the Pale blue dot by Carl Sagan. His voice is soo smooth and relaxing that sometimes I just hear it for his voice even though the content is nothing less than amazing.

P.S. Unfortunately Sagan died before the book recording could be completed so some chapters are in a different voice. Still, listening to it is real zen like. Here is a sample[1]

I’m pretty confused by this post. What would you identify their priorities as?

Regardless, as a person not a fan of windows (not worth learning a unix alternative), I would argue it’s the polish that makes the experience worth it, not some better engineered experience. For instance: working with variable DPI seems to be trivial, whereas it still seems years off in Linux. Same with printers and notifications and internet and almost everything. These aren’t feats of engineering per se, but they do indicate forethought I deeply appreciate when I do use windows.
On the other hand, transit in Tokyo and Osaka is run by a number of public and private companies, some of which compete with each other, and linked-up journeys are no problem at all. It's totally doable.
May I ask where you work? And also, why bitcoin? It's a slow cryptocurrency right?! Do you make users to wait for confirmation(about 30-40 mins)? You could experiment with fast Altcoins and convert to Bitcoin eventually.

I'm skeptical of this claim.

From the Cardano paper [1] p. 47,

> Even if the attacker could find a strategy to generate an alternative chain with valid leader selection data, presenting this chain and its blocks generated at slots that are far ahead
of time would not result in a successful attack since those blocks far ahead of time would be rejected by the honest stakeholders and the final alternative chain would be shorter than the main chain.

At first glance, the attacker then needs to gain the keys for almost all of the bonded stake at some point in the past. This is obviously a stricter requirement than holding keys for 2/3+ of the stake at some point in the past, but still seems remotely plausible when targeting the small set of validators in the early bootstrapping period. Remember also that these early validators could be totally cashed out of the system and thus have actually have no disincentive not to sell their keys.

Actually, even controlling only 2/3+ of some past stake, the attacker can likely grind on the randomness beacon outputs (since they control all the shares) to ensure his controlled keys have near 100% of the slots in the next epoch. Then the long range fork would be of a similar or possibly even greater length than the honest fork.

> 1. Green can relieve visual fatigue and aid in inspections

> In the early days, due to technological restrictions, quality inspections relied on workers manually checking the boards with their bare eyes. Squinting at tiny circuits all days is tiring work, but neurologists and psychologists agree that the wavelength of green light has relaxing effects on the body and can reduce fatigue. Additionally, they have found that the sensors in human eyes, or cones, are most sensitive to green light. Therefore, the contrast is greater between the circuit traces, pads, silkscreen printing and empty spaces. Just by observing the boards from the outside, one can easily identify defects in the outer layers. Compare the below images of green boards to other colors such as blue, yellow or even black and white. With higher contrast, errors are easier to spot.

Perhaps an IDE theme with a green background would be similarly helpful for programmers. Any particular suggestions?

But someone built Telegram with it, which is of fairly equivalent complexity (https://aozoeky4dglp5sh0-zippykid.netdna-ssl.com/wp-content/...).

Besides, I'd say that there are enough quality Qt apps in the KDE ecosystem to not need $ELECTRON app :-) just yesterday Krita was making the highlights for instance. Likewise, I doubt people being used to the power and speed of KDevelop or QtCreator would feel the need to switch to VSCode.

Even going outside of the "libre" ecosystem, there are many many many nice-looking recent apps written with it... take a look at substance painter (https://www.allegorithmic.com/sites/default/files/DML_1.jpg), the Blizzard launcher (https://i.kinja-img.com/gawker-media/image/upload/s--zbfvud8...), Native Access (https://support.native-instruments.com/hc/article_attachment...)...
I still scracth my head as to why doing a kernel update of Ubuntu running under Hyper-V on a spinning disk is so horrifically slow. If I migrate the VM while it's running to SSD, let it finish, then migrate it back to spinning, it's faster then just letting it update in place. This is my device desktop, otherwise I would put in on SSD full time.

The above comments make me think something like the stat calls may be the issue and moving the running vm to SSD hides the problem. It obviously isn't raw disk rate at the point.
Hey. Thanks for Redux, and thanks for this blog post. It’s refreshing.

I suspect it's a deliberate choice both as a fashion statement and to discourage repair.

It's interesting to see a similar phenomenon with desktop PC motherboards: "gamer" or otherwise "enthusiast" boards are often a non-green colour and come with superfluous design elements (like plastic covers over the actual components, which sort of remind me of the engine covers on newer cars...), while both the ultra-cheap prebuilt and ultra-expensive server boards remain green and free of fluff.

Is there any viable alternative to PayPal for a EU-based micro-business wanting to accept CC payments from North American customers?

I run a legally operating one-man business providing electronic services to customers (mostly other businesses) in EU, US and Canada. The EU customers pay me with bank transfers like civilized human beings, but Americans and Canadians always insist on PayPal because, apparently, North American banking system charges an arm and a leg for international bank transfers, so they'd rather pay with CC.

I didn't mind having to provide PayPal with scans of a bunch of sensitive documents. What I do mind is pretending my PayPal balance is not real money but virtual tokens with little legal protection and the possibility of being arbitrarily frozen for an undisclosed reason. That, and their horrendous fees (including currency conversions based on rates they pull out of the ass) for which they don't even provide anything resembling a legal invoice (a screenshot of an HTML table won't cut with my IRS).

Someone, for the love of God, tell me there's an alternative a teeny-tiny business like mine could use.

Another reason Walmart killed it was because they offered more convenience at a lower cost. That’s what people choose.

It’s also why people choose vehicles over public transit: point-to-point convenience for comparable prices to stringing together public transit and car services to get around.

It's not a matter of money, resources, or talent. For reference: The Mythical Man-Month, waterfall process, Windows Vista.

Building something of this scale and complexity from scratch will take a lot longer than even the most conservative estimate and will take many more years to shake out the bugs. Again, remember Windows Vista? And that was not nearly as revolutionary as the things you suggest.

You assert that there's nothing immoral about weapons development, and go on to almost directly contradict this- noting that "force/battlefield superiority" tends to lead to the use of these weapons, killing people. I really don't see what your point is; are you trying to argue that an occupation that leads to unnecessary human deaths is moral?
> If Company A doesn’t give you a good deal on your healthcare, Company B will

Then when you need to make a claim you discover that Company B gave a good deal because in the fine print they added exclusions that result in your claim being rejected for some arbitrary reason. So yes, in the long term the competitive landscape works as word gets out that Company B's plan is garbage, but in the short term you are forced into personal bankruptcy or a worse health outcome.
Although the equipment will still need to be maintained in the field, which means needing lots of technically trained people unless they want to just leave thousands of these littered around for the simplest breakdown.

> And don't do that "C:\Documents and Settings\John Doe\My Documents\My Projects\Books\". There is no point in storing your things deep in a thousand rabbit holes

That's the standard way Windows users are meant to store their data (although I don't). What is "\home\jdoe\" on Linux is "C:\Documents and Settings\John Doe\My Documents\" on Windows ("C:\Documents and Settings\John Doe\" actually but not from an ordinary user point of view).

> It's overzealous hierarchy fetishism.

I actually find it sad we are still using hierarchies for that when we could be just using tags and semantic attributes instead (semantically a document file doesn't even need a "file name", the actual document title stored as an atribute or as a record within the file is enough and actually better). Apparently it seems ordinary people are more comfortable with the folder metaphor and hierarchies so WinFS was cancelled and 3rd party tagging and semantic desktop systems are little know.
> The point of the capital investment in the pipeline is that the overall cost will be lower than shipping it from the pacific.

Lower, maybe. But transoceanic shipping is cheap and gives you far more flexibility in sending to whichever customer will pay the most.

> If the pipeline doesn't exist, it may not be economic to mine the tar sands

The current problem is that the capital investments in the extraction infrastructure have already been made. It's cheaper to continue operating them at a loss than to shutdown entirely. If the operations go bankrupt, they'll continue operating when a buyer can take over without any of the previous debts.

It's at the point where it's taking government intervention to get the extractors to reduce production. The most economical decision for them is still to flood the market with production.

It's like the Worldcom fibre infrastructure constructed in the 1990s. It was a terrible investment, but once it's built, it's not worth turning off.

> the majors are integrated and having an alternative supplier to feed their refineries is good for them.

If they're integrated and have a balanced production and consumption, a pipeline from somewhere else throws a wrench into that.

> externalities: the pipleline itself, of course but more importantly leaks. Keystone's other pipelines leak and there's no reason to believe this one should be any different.

Pipelines will always be the best way to move bulk liquids from A to B. There are also externalities to oil-trains and more expensive oil.

I smiled at your characterization. Although, more realistically, our archetype has done modestly well by working for the man, and has 100k-low millions in index funds and company stock, and some comfort with +/- 30% swings y/y.

But let's also remember, that middle-aged character has seen the hype cycles many times before in previous decades, and recognizes the scam. The sky-high and unstable valuations, the co-dependent press coverage, the hand-waving distraction from the absence of realistic uses, the flurry of me-too startups, the enthusiasm of lay investors.

Hype usually indicates pure bullshit, but sometimes something useful emerges out of it. Most often the original projects are decimated.

(Your edit makes my reply make a lot less since since you removed all of your original questions, but I'll leave my original reply, read the part after number 7)

My set up is basically this:

1. I use WSL as my day to day programming environment with the Ubuntu WSL terminal + tmux[0]. It's where I run a bunch of Linux tools and interact with my source code.

2. I have Docker for Windows installed (since the Docker daemon doesn't run directly in WSL yet due to missing Linux kernel features like iptables, etc.).

3. I installed Docker and Docker Compose inside of WSL but the daemon doesn't run in WSL. I just use the Docker CLI to communicate with Docker for Windows using DOCKER_HOST, so docker and docker-compose commands seamlessly work inside of WSL from my point of view[1].

4. All of my source code lives on a spinning disk drive outside of WSL which I edit with VSCode which is installed on Windows.

5. That source code drive is mounted into WSL using /etc/wsl.conf at / (but fstab works just as well)[2].

6. That source code drive is also shared with Docker for Windows and available to be used as a volume in any container.

7. All of my Dockerized web apps are running in Linux containers, but using this set up should be no problem if you use Windows containers I guess? I never used Windows containers, but that seems out of scope for WSL / Docker CLI. That comes down to Docker for Windows.

But, it's worth mentioning I have installed Ruby directly in WSL and didn't use Docker, and things are still just as fast as with Docker volumes. In fact, I run Jekyll directly in WSL without Docker because I really like live reload and I couldn't get that to work through Docker. My blog has like 200+ posts and 50+ drafts, and if I write a new blog post, Jekyll reloads the changes in about 3 seconds, and that's with Jekyll-Assets too. I have a feeling it wouldn't be that much faster even on native Linux since Jekyll is kind of slow, but I'm ok with a 3 second turn around considering it does so much good stuff for me.

> Is it that they don't get stressed, or that they are great at hiding it to project an air of confidence at all times.

I wouldn't say it's that they don't get stressed, but that they are able to quickly compartmentalize it and move on without dwelling on it.

On the "are they just great at hiding" question, at least in my experience this isn't really possible. Personally, I have severe negative physical effects in response to long term, chronic stress. I sleep poorly, get severe intestinal issues, etc. At some point it becomes pretty impossible for me to just "hide it" - I'd LOVE to be able to quiet my body's physiological responses, but I'm just not capable. In seeing how some of my colleagues dealt with the same stressors, I can assure you they weren't just "hiding it" - if they were experiencing the same physical effects I was, at some point it would have been impossible to hide.

That's how an economically careless welfare state works in a capitalist economy. What you are describing is social democracy, which is not the same as socialism and never has been in the history of the movements or any terminology recognised by social scientists.

Socialism is direct worker control over the state and social means of production (to the point where Karl Marx considered the term synonymous to "Communism"), while social democracy is a liberal capitalist economy in which the government (which owns very little social means of production itself) funds welfare programs through taxes.
Has to be some kind of caching issue ...
Madison, WI, USA has a section where cars are mostly not allowed. When I was a kid, it was a major retail destination, and people would make weekend trips from an hour or more away (by car) to go there.

There was recently a huge wave of shops closing. They've since been replaced by restaurants and cafes, and they seem to be doing well, but nobody's going to go into ten restaurants in a single afternoon, so the area still feels less alive than it used to.

To me, though, this particular phenomenon feels like an extension of the death of the American shopping mall, and not evidence that a city with an outdoor environment designed to accommodate its own residents (and not just their cars) wouldn't be nice. If it's just a business district that's designed for pedestrians, well, that's really nothing more than a public version of the outdoor shopping mall.

I'm most definitely not looking for a shopping mall. I'm looking for my kids (and me) to be able to go outside and ride a bike or kick a ball or organize a neighborhood game of tag, without being dependent on me to drive them by car to the nearest city park in order to do it. And I'm looking for a culture where neighbors collectively spend time outside, together, as a community, rather than being cooped up indoors or walled up inside their own back yards because the neighborhood's public space is a fundamentally uncomfortable place to be.
