I like this reboot idea. Let's say all engines (and many railcars) could have an ESP32, and all engines have rechargeable batteries. Then savings could be found by using commodity track that does not need to carry control signals and does not need to conduct electricity (neither AC nor DC).

Optional conducting couplers might enable DC power from engine to cars, and from reserve batteries (in boxcars or whatever) back to engines.

An issue is how to transmit control signals to engines, accessories, signals, etc. Bluetooth? Wi-fi? Something else? It should be something built into the cheapest boards. And ideally it could support streaming video from engines.
The USA is really hostile to anyone who doesn’t want to have a car or perhaps more importantly can’t have a car. Who can’t have a car? People with certain disabilities for one.

Not a car-centric life has its origins in keeping poor people out and redlining. Now neighborhoods might not be legally segregated (sunset towns still exist however) but if those houses are so expensive that poor people can’t afford them then it amounts to de facto segregation.

You will hear counterarguments like “how can a highway be racist?” but when you look at what neighborhoods were destroyed to make room for that highway and the net effects of intergenerational wealth creation it turns out a highway can be racist.

Even something like turning right on red is so hostile to cyclists and pedestrians. This was originally introduced in the OPEC oil crisis to reduce car idling but despite clear evidence that it increases danger to cyclist and pedestrians it’s still here. Why? Driver convenience trumps everything.

When it comes to walkability most Americans still want their cars and will nearly always choose more space over walkability.

Even when they do want walkability what they talk mean is they still want their large house on an acre lot that happens to be walkable and that just doesn’t scale.

I also believe that America’s car worship contributes to the profound selfishness and lack of empathy of most Americans. It’s a bubble that allows you not to have to deal with other people.
This is the next step in the nudge to move off Heroku for us. We obviously use paid instances for production, however we use a Pipeline and the free instances for staging as well as short lived test instances for git branches.

We were planning to move off anyway, but this isn't a change that would keep us. A price change to make Heroku competitive would have potentially kept us on board.

I don't think Heroku can ever be competitive by remaining a layer on top of AWS.

GC makes hard real time harder. Way worse than malloc.

GC usually works by amortization. 99.99% of allocations are hella fast and then there’s that one that triggers a one second GC that stops the world. There are algorithms to “spread out” the GC cycle over some span of time during which you interleave the GC and your actual code. But then proving that this is schedulable in the worst case is hell. So much hell. I get that real time is hard anyway already. GC just makes it worse.
This is an oddly dour announcement presented in a positive light. The announcement is basically of deprecations and a roadmap where very little is about actual features or improvements (outside of security).
Agreed. I love the fact that so many create ebooks for free and I'd love to support them with a print copy. Print on demand through Amazon or Lulu would be perfect and (I assume) fairly easy to set up.
Your positive examples all have one thing in common: they're not happening in cities. Just because a car makes sense in the countryside or beach does not mean it makes sense inside of a city.

A problem with our approach to urban planning is that we get large, sterile apartment buildings or detached single family homes but absolutely nothing in between. If that missing middle was allowed by right, you'd find what I enjoy right now: both human connections and a car-lite lifestyle.
"I reject your reality and I substitute my own."
Bummer. I’ve found it really convenient, and I’ll consider moving to a paid tier, but they had a DNS outage earlier this week that left my site down, and even though they said it was upstream, it makes me wonder whether I shouldn’t move to a more stable host. Guess I won’t be adding any user facing features for a while as I work out the transition in my spare time.
> Also, you really don't have to travel to realize that life can be different elsewhere.

I think you sort of do, or at least I did.

I like to think I realized quite well that life could be wildly different throughout the world - it's what motivated my initial travels.

Hearing about how the Netherlands does transit vs. actually feeling and experiencing it immersed over a month of living there is just an entirely different level of understanding.

In this example I went from thinking the NL style transit is pretty neato, to now thinking that transportation is one of the most fundamental pieces that forms a society and it's future. It's not just energy and moving mass around. Get transportation wrong and you will fundamentally break society in unexpected ways.
What's funny is that I'm far from an Apple lover and I could be accused of being a shill for removing the headphone jack. I was initially skeptical, but it forced me onto bluetooth headsets which had come a long way up to that point. I listen to podcasts quite a lot, and I'd often snag the cord on door handles (it's amazing how catchy that cable could be), and audio quality isn't a huge factor. So overall it was a good change for me.

I feel the opposite about touchid if it matters. Honestly it seems forgotten, but I much prefer the intentionality of touching my phone in order to unlock it as well as having a physical home button.
heroku was great but their free pricing was almost too good. and once you were out of the free range, their pricing jumped too steeply. they should have had a much more gradual ramp-up as your app got bigger and needed more resources, more of a geometrically rising pricing curve rather than a discontinuous one (but not like the overly complicated aws pricing, by the nanosecond on 15 different dimensions).
How would apple know that my app contains my own custom interpreter? It's just a program that takes raw strings (whatever the source may be) and behaves in some arbitrary way according to the string. How can this be detected automatically? Looking for a certain interpreter patterns (e.g. A big switch)? I imagine this would be extremely fragile to false positives and also code can be automatically obfuscated arbitrarily (convert the switch into if-else trees and spread them across subroutines).
France allows dual citizenship and you can apply after five years of residence.

SFML can export to Android, but to me the biggest drawback is lack of Web export. In the current gamedev scene, web export is super popular for tiny games (specially for game jams, where it's just more convenience and also secure to share and try other games).

In today's world where so many tools offer web export (from libs to frameworks to engines), I can't justify learning a tool that doesn't support it.

The paid version (nginx plus) has a few additional features that you often end up needing/wanting (the dashboard for example, for ops users) in enterprise environments.

For what its worth, I switched from nginx to Caddy years ago and haven't looked back - Caddy's built in support for LetsEncrypt and zero configuration for the most common reverse proxy scenarios is just too compelling to ignore now - the speed and ease with which one can throw up an SSL front end with valid letsencrypt cert is amazing.

You're referring to Vienna. It's broadly part of Europe and narrowly functions as its own city-state. Its intermediate allegiance may be less important.

It's long had outsized musical influence but was only the world leader in music during the classical period, roughly 1750-1820. This does not overlap Austria-Hungary. However, I don't know the economic output of the Habsburg monarchy relative to the rest of Europe, so it may still be an exception.
Is there a tech stack or language that allows us to write formally proven and real-time (bounded-time tasks) for embedded systems?

Removal of Heroku Free Product Plans FAQ
This seems like scare-mongering, or FUD, in my humble opinion.

The reason that sewage and water is so hard to get right in the United States is in part due to sprawl, as well as the lack of political will to actually maintain infrastructure once it is built.

A bit of a deflection I'll admit but - look at the NY subway. It barely receives the funding to keep basic maintenance afloat. Compared to equivalently sized systems in Europe it fails because there's a massive political diaspora to overcome since culturally taking transit is "for the poors" (you know what that translates to) and we can't be giving them anything.

Similar holds true for sewage and water (for water, look at Flint Michigan). Housing, transportation, zoning, etc. are all the same problem. The reasons we fail at them are all connected and without taking a holistic approach we likely will remain bad at it. Pointing to any one thing and claiming "well even if we do that we'll still suck at 99% of everything else" isn't really a helpful description of reality, it just means there's more work to do.

I guess what I would really push back on in your argument is the point that higher density requires higher competence. At some meaningless level, sure, we have engineers that have to solve harder problems. But the reasons that the US is bad at a lot of urbanist policies isn't because we lack competency (you could just hire people from overseas) - it's because we've allowed ourselves to build a system that incentivizes that incompetency at multiple levels through restrictive zoning, endless veto privileges a la "community feedback" / NIMBYism, car culture and the social disdain for what is perceived as normal in other countries (trains, bikes), etc.

This isn't a problem with the US geographically or its people, and the problems have solutions. I think if you talk to most people in cities they probably agree wholly or in part on a lot of fronts, even if there's still a prevailing "got mine" attitude depending on where you ask.
Problem in Denmark is that every small town wants their own university.

> Square foot by square foot, Manhattan land is far more expensive than San Jose.

People can't finance land. You finance housing. Sqft / sqft for housing, Manhattan is not much more expensive. The land is much more expensive BECAUSE you can build much more housing.
Digital Ocean has 3 free apps as far as I'm aware. Those have basically been super easy to setup and forget for me. I have a few websites running off it for a couple of years with no maintenance on my part.
Well connected - and I think this comparison is becoming more apt each passing day.

These statements and policies are just so… egotistical… for lack of a better word. What happens when we stop agreeing on what the “good” is? How can you claim to respect all humans when you don’t respect the human cognitive ability to disagree?

Thanks for posting.
Haha that's awesome! It was such a good idea – I personally use that feature all the time.
That depends on your use-case. In general I would recommend you consider purchasing Nvidia's GPUs for the best price/performance and GVM support. Intel's Xe architecture is currently improving but the performance isn't quite there for a number of use-cases however some appear to work quite well and I expect that will improve with time. The 2080Ti works well with current software. If you are a developer and would like to help us improve support for devices you can purchase a 3090Ti (support in GVM for this device is under active development).

> It's intended for people who have different fashion tastes, tastes that approximate political positions that I don't hold.

As a Canadian living in the heart of supply management (i.e. state ownership of the means of production) country, where supplies are provided by the so named and literal Co-op (i.e. community ownership of the means of production), trucks are very popular. In part because they are useful tools in carrying out the business within that socialist system, but also because outsiders emulate to try and convey similar social standing.

If there is a political statement to be found in there, which may be a stretch, to me it would be that trucks = socialism. But when I look beyond my bubble, I'm left with the impression that trucks are, if anything, especially stateside, a statement at the compete opposite end of the spectrum.

What approximate political position do you believe is inbuilt into the design of modern trucks?
I have a hard time pinning down why it's so hard to read. I think it's because some of your sentences aren't actually full sentences.

Examples:

"But often, especially with nascent projects, we can’t afford."

"From full backend-as-a-service solutions like Firebase, to tools like ORMs to abstract and simplify dealing with databases."

"Simple, with an architecture that already internalizes all of the common issues seen when handling events."

You also sometime use sentences that are too verbose or hard to parse.

Example:

A) "In this post we’ll show how the lack of good abstractions leads to build-your-own backends lacking a key component that is present in most modern backends: a message queue."

B) "In this post we’ll explain why message queues are important to a good back-end, and why developers may overlook them. (part that doesn't need to be said: because of the focus on database-centric abstractions.)"

A) "If you ask most people, a backend is comprised of a database where the data can be stored, a business logic layer to mediate access to that data, and a couple of authentication components. But if you ask modern backend engineers, the answer differs. Yes, you have all that, but there’s a major component missing in this picture: a message queue.

From modern alternatives like Redpanda, to established systems like Kafka, message queues are an integral part of most professional backends in use today."

B) "Most modern back-end engineers will attest that a message queue, such as Kafka or RedPanda, is crucial to a good back-end."

Generally I'd get rid of the conversational, quirky tone, I think it'll improve things stylistically.

For the content itself I'd write a clearer plan with titles and subtitles, and the idea you want to convey in each paragraph.

Also a good tip is to always write the introduction at the end, it makes it clearer in your mind what you're actually trying to convey.
Yeah that's very true. Perhaps I don't mean "evolution" in a classical sense but rather: animals probe the world, and behaviours that aren't discouraged somehow are more likely to be replicated among the community.
I appreciate the reminder. I work at a smaller place and boy am I all over the place depending on the work that's coming in.
That’s just wrong. The village I come from in germany has 8000 inhabitants, pretty much only single/double houses, practically no flats and perfectly walkable. Multiple bakeries and grocery stores, never further than 15 minutes walk.

It’s just that these small groceries cannot outcompete supermarkets once people are in the habit of going everywhere by car.
I'm pretty lucky for an average American, all things considered, and live in an area with a grocery store 15 minutes away by foot, and most everything else under 30 minutes by bike. Public transit isn't amazing, but there's 60 miles of light rail and a decent bus network. My family of 4 still needs (wants?) one car, but we only put about 8000 miles a year on it.

All that said, I feel a bit trapped here. I've yet to find somewhere else in the United States I'd like to move to if I had to move. Manhattan would be fun, but whoa boy...

Also what I'm using, but it has no free version at all, so if what people object to is having to pay, they're not gonna like it. Personally, I actually like paying for stuff I find useful, preferring that to the ad machine.

For anyone who doesn't want to follow a link, MacroFactor's killer feature is you input your daily weight and your food and it creates a smoothed estimate of your non-water gain and loss in order to be able to give you a pretty accurate estimate of total daily energy expenditure after a few weeks. That way, you not only track what you're eating, but you know exactly how much you should be eating as well, in a way that is the only way short of checking into a metabolic ward to know your own body's true energy usage. Any other system out there is just guessing based on sample averages from past studies of other people.
Speaking as a pure hobbyist with no formal background in programming or computer science, I've learned a ton playing around with free Heroku dynos. That "holy shit, it worked" feeling is a hell of a drug.

My proudest achievement so far is a dumb-as-rocks little Clojure program that runs on a schedule in
a free Heroku dyno. It sends alerts to a Slack channel when there's updates to a Trello board we use at work. All it does is ping Trello's API, check for changes in the new state against a Postgres Heroku add-on that stores the last seen state, and then send formatted messages based on the diff to a Slack channel for me and the few coworkers of mine who pay attention to it. It starts up hourly in a Heroku free dyno, runs for six or seven seconds (JVM lol) and then goes back to sleep. But I'm super proud of it because it's actually useful and I made it myself instead of relying on Zapier or IFTTT or something like that. It sparks joy for me every time I see that it ran correctly.

Now I'll have to find somewhere else to host the little thing, I reckon.
Just wait until cheap to write GPT3 articles learn SEO techniques inherently and bombard the internet suppressing human writers in the spam ocean. At https://aquila.network we’re always thinking of this scenario.
If orcas live for decades, have memories, and have language, then they're telling each other stories about us. The Southern Resident Killer Whales are down to 70+ beings. They've probably figured out by now that humans are the ones responsible for their food supply getting decimated. I suspect orcas everywhere are trying to figure out ways to communicate with us and are doing an amazing job.

They probably haven't accounted for human denial and human-centric science. These two things lead to scientists being like "Gee! I wonder why they're parading their dead babies and carrying them around? They must be grieving!"

As opposed to a slightly more realistic interpretation:

"They must be grieving and are trying to tell us 'See what you're doing to us?'"
Wow, awesome tool! Seriously, thank you for this. This really brings back that sense of wonder I experienced when I was younger and began exploring the internet in the early 90s
I don't think this is correct. The camera is applying a PSF (point spread function) to the image. If you have a known target image you can find the inverse of the PSF and apply that as a correction (deconvolution).
I just hire one on the rare occasion it's needed. Public transport otherwise.
As recently as 1960 [1] their fertility rate was above 6. The neat thing too is that we can actually fill out the missing data perfectly due to the fact that the relative population sizes will always be driven entirely by fertility rates. A fertility rate of six means each older group will be exactly 1/3rd as large as each younger group, similar to how a fertility rate of 1 means each older group will be exactly twice as large as the younger group.

So here is what the table looks like if we assume that Year 0 was the final year of 6 fertility:

(148) Year 0: 4 sixties, 11 forties, 33 twenties, 100 newborns,

(194) Year 20: 11 sixties, 33 forties, 100 twenties, 50 newborns

(208) Year 40: 33 sixties, 100 forties, 50 twenties, 25 newborns

(187) Year 60: 100 sixties, 50 forties, 25 twenties, 12 newborns

(93) Year 80: 50 sixties, 25 forties, 12 twenties, 6 newborns

(46) Year 100: 25 sixties, 12 forties, 6 twenties, 3 newborns

(23) Year 120: 12 sixties, 6 forties, 3 twenties, 1 newborn
