Isn't it possible to just set the haproxy maxconn to a slightly lower value than what the backend can deal with, and then let the reverse proxy retry once with another backend? Or even queue it for some hundreds of milliseconds before that?

This way you avoid overloading backends. Also, haproxy provides tons of real-time metrics, included the highwatermark for concurrent and queued connections.
Apologies, it seems I misread the tone of your words.
I'm thinking of starting a blog soon, does anyone know if the popular static site generators (Hugo, Jekyll, etc.) have trivial support for RSS?
Cloud is supposed to be where downtime isnt a thing, or isnt really possible (minus dns of course.)

Someone elses computer, without failovers, will never be "always up."

Someone elses computer is just "hosting." A cloud is a datacenter, not a server.

Your own computer available from anywhere on the internet is just "remote access."

Cloud has always meant either distributed computing or complexity abstracted away because its moot and only the resulting service matters.
As someone who hand-codes their RSS feeds and doesn't include article content at all (just a title/link/description), what's the recommended setup for this?

Can I just spit the raw HTML at you? Do I need to inline images? I'm assuming that someone who's consuming a full feed isn't going to want any CSS included.

I'm not against this, but I'm also hand-coding all of my blogs, and this seems like a problem that would be more easily and more consistently solved by a user-run service like the one you've made. I don't know what readers currently support, and I'm looking around quickly on DuckDuckGo and not seeing many resources about generating full-text feeds that don't boil down to, "click the button in Wordpress."

Again, I have no problem supporting this, but if I'm going to put the time in to change my blogs, I kind of need more prodding than just one or two people saying it annoys them. I don't have any specific reason I wouldn't want to accommodate people like you -- I'm not advertising on my blogs and I don't have any analytics, so I don't care where you read. But I don't want to invest a lot of time into building a completely new content pipeline.
Small and medium cities aren't so much an issue. 400k people can easily live in a midwestern car-centric metro area. But once cities grow to from hundreds of thousands to millions, then they need to start being redeveloped with a car-free livestyle in mind.

Greater LA is home to nearly 20 million people. It's entirely feasible to create several car-free neighborhoods, each with more people than Omaha Nebraska. That's plenty enough people for transportation solutions to evolve organically.

Something to keep in mind is the existing suburban infrastructure is also unsustainably expensive. It's quite likely that many American suburbs will decay in the coming decades, a la Detroit, as poor residence can't supply enough tax dollars for maintenance.
I've worked on two (2) substantial production Elm applications.

1. Healthcare

Fall 2017, I started integrating Elm into an AngularJS application after experimenting with it on a couple of side projects. After a successful initial feature, I convinced the team to use it for new features. Another couple of developers helped to create the initial version until late 2018. We started in Elm 0.18 and converted it to 0.19. Now a sole part-time college student maintains and adds new features to it.

2. Transportation management

Since January 2019, I work on an Elm project, once again weaved into an existing AngularJS app, with ~34k lines of Elm code. I inherited it with no interaction from the previous developer. It looks like it was introduced in mid-2017 and is currently on Elm 0.19. Although it is not perfect, not always following best practices, it is much easier to maintain than anything I've worked on in the past. On JS apps, I've torn my hair out trying to figure out what is going on and attempting to add new features.

With Elm, I refactor daringly and rest more easily.

Please let me know if you have any specific questions.
Nearly 10 pages of Gibberish with little to no substance. Doesn't mention anything about it hardware or programming model.

This looks great. I hadn't seen this before. Thanks for sharing.
I wonder what peak concentration can be reached by cycling pure water through a micro-sprayer. I'd be skeptical if this could make rocket fuel, but it would be extremely cool if it could.

Turning ice asteroids into usable fuel would make space much more accessible.
I make (web app) components with only minimal regard for cross project reusability. I don't add any features to them that I don't need for the current project, but I do try to keep them small and decoupled.

I find that liberal use of copy-paste _across projects_ is way cheaper than building up a library of well thought out, generic components even in the long term.

If you have ten concurrent projects that need the same components at the same time it could make sense to build them up as privately published libraries. Otherwise it's unlikely that the overhead and rigidity of that approach will pay off if you only have one or two projects that you're actively working on at any given time.
This appears to be strongly based on Alasdair Wilkins' 2010 piece on Gizmodo, at https://io9.gizmodo.com/the-forgotten-genius-who-discovered-... .

Consider the quote from this essay by Enright:

> Born in 1724 in the small village of Eakring, Nottinghamshire, Michell studied at Cambridge University. A true polymath, he later went on to teach there, instructing students in everything from Hebrew to geology. In 1761, Michell was elected as a Fellow of the Royal Society, before settling down to the position of rector at St. Michael’s Church in Leeds in 1767.

with that in Wilkins' article:

> John Michell is one of the great unsung geniuses of 18th century science. Born in 1724, he studied at Cambridge University and later went on to teach there, instructing students in everything from Hebrew and Greek to math and geology. He was elected to the Royal Society in 1761, but in 1767 he left for northern England to take up the the post of rector of St. Michael's Church in the city of Leeds, where he spent the rest of his days.

Or, this essay by Enright says:

> He made significant contributions to our understanding of electromagnetism and is often regarded as the father of seismology, having discovered fault lines, rock strata, and the wave nature of earthquakes. Michell also devised a method involving torsion fibres to determine the mass of the Earth.

Wilkins' article:

> His speculations on earthquakes proved remarkably prescient, writing that earthquakes act like waves of energy beneath the Earth and that they are caused by discontinuities between different strata, essentially predicting the existence of fault lines. All this work earned him the later title of the father of seismology, and he developed a method to very accurately measure the mass of Earth.

(Note that https://en.wikipedia.org/wiki/John_Michell says more directly Michell "introduced the idea that earthquakes spread out as waves through the Earth and that they involve the offsets in geological strata now known as faults.", making Wilkins' description more accurate.)

Enright:

> Combining these two insights, Michell devised an ingenious method by which the mass of stars could be determined by looking at how much the emitted light was slowed down by the pull of gravity.

Wilkins:

> Michell came up with an ingenious method to work out the masses of stars, figuring that careful calculation of the speed of light coming from a given star would reveal its gravitational influence and, in turn, its mass.

To be fair, Enright includes things which Wilkins does not cover (and vice versa). However, Enright's overall organization is quite similar to that of Wilkins' 2010 article - enough that I can't help but wonder about the connection between the two.

How does that deal with customs and inspections?
I think this is what John Gruber does for the Daring Fireball RSS feed.
What assurances do the riders have that the vehicle they're riding in is mechanically sound? That their driver doesn't have a history of violence? What happens if a rider damages the vehicle?
Is he worth that much though? Everyone seems to paint him as a genius, but is his value 5x the other engineers on the team? 10x? 100x? It seems like there are plenty of smart and talented people you could hire for your self-driving car initiative that are 1% his price. Or, flipping it around, if self-driving engineers are really worth $100MM+ then maybe they should band together and work for themselves.
I wondered this as well. In many of the intermittent fasting studies they kept caloric intake the same and showed that the benefits applied even when taking caloric restriction out of the equation.
This is a somewhat different take, and quite possibly impractical.

The main thing I've done over the years to get reasonably 'good' at the Linux kernel (and quite a few other things) has been to read every technical article appearing in https://www.lwn.net/, every week, in full, even if I didn't really understand the material. I've been doing that since 1997, and it's paid off quite well.

Also: please buy a membership, even though you don't have to. It's well worth supporting.
I’m not aware of any news site or blog that doesn’t still support RSS.

As far as difficulty in monetizing, John Gruber has been making quite a bit of money for years selling one RSS entry at the beginning of the week and a thank you post at the end of the week.
There are no consequences. What objective criteria could they possibly use to prove you falsified your application?
Sounds like an automated version of Pocket, which has been around for ~10 years and is now owned by Mozilla; so the legality aspect of it shouldn't be an issue. I use it daily, although recent versions of the app send you to the original article page, ads and all, should you dare to open it with data/wifi active. Airplane mode still pulls up a text-and-image only version of the article.
I love these sorts of write ups. I wish there was a way to encourage internal transparency like this, as opposed to my least favorite way to be greeted when I let someone know about an issue with their product: "Can you try again?"

Nothing as infuriating as that, it could be a valuable learning lesson for many people just like this!
Street parking should be priced such that approximately 15% of it remains empty. If the street is getting full of residents, then the price should go up. Until the point where it makes financial sense to build more parking or have less cars. If street parking cost even just $0.50/hour, it would make more sense to rent a car for the occasional weekend trip instead of keeping it on public land.

I would highly recommend The High Cost of Free Parking, which talks about this extensively.
super cool!

This is 100% not about me... it's about trying to understand the phase in a startup/ company's lifecycle from an academic perspective... I'm trying to learn.

To directly answer your question I wouldn't start a company and have it be undercapitalized. It's just not my scene.
Famous Graphics Chips: Microsoft’s Talisman – The Chip That Never Was
Money quotes:

> Internet service providers (ISPs), such as Verizon, Comcast, AT&T and Charter [...] have deliberately restricted competition, kept prices high and used their armies of lobbyists to persuade state legislatures to ban towns and cities from building their own public networks.

> ISPs have been able to get away with fostering pseudo-monopolies because they spend a lot of money to keep the regulatory environment and the conversation surrounding it murky. FCC Chairman Ajit Pai, a former Verizon lawyer, has been an effective agent for ISPs. He led the charge to dismantle net neutrality last year, and he has done everything in his power to stop municipalities from building their own broadband infrastructure.

> Horror stories starring giant Internet companies are practically universal. In the wealthiest country on the planet, we lag behind many other developed nations in connectivity and speed, while also paying more for that service. That’s why companies such as Comcast consistently rank as the United States’ most hated companies by consumers. When you eliminate a competitive market and replace it with regional monopolies or duopolies, providers have no incentive to improve their service.

The proposed solution is federal grants to enable electricity and telephone cooperatives, nonprofit organizations, tribes, cities, counties and other state subdivisions to provide broadband internet in their local markets, thereby creating competition for ISPs.
Well, figuratively, anyways.

> What Serge did not yet know was that Goldman had discovered his downloads just a few days earlier, months after he’d made the first of them. They’d called the F.B.I. in haste, just two days before, and then put their agent through what amounted to a crash course on high-frequency trading and computer programming. McSwain later conceded that he didn’t seek out independent expert advice to study the code Serge Aleynikov had taken. (“I relied on statements from Goldman employees.”) He himself had no idea of the value of the stolen code (“Representatives of Goldman told me it was worth a lot of money”) or if any of it was actually all that special (he based his belief that the code contained trade secrets on “representations made by members of Goldman Sachs”).
I believe the word for this is Torschlusspanik https://en.wiktionary.org/wiki/Torschlusspanik - and sums it up nicely.

I'm a kind of morbid person by nature, but the more time goes on the more I realize that awareness of my mortality is helpful for getting me off my ass to get things done. Not necessarily work, just life in general. I wanted to live abroad "someday" and finally tried it when I was 30 (in the nick of time, it turns out). I wanted to start a company, and see now how it would've been 50 times harder to do it with a child than without. In my 20's I always thought I'd get around to going on X trip, maybe asking out Y girl, etc. and instead wasted 9 years in the same town doing not much of anything. Fortunately, the last 9 years have had a lot more going on.
Sample size was small for the ADFs (approx 40). They were compared to control of 60. I didn't drill deep enough to see age and/or gender breakdown.

That said, fasting as pro-health tool keeps coming up and the gist time and again seems to say it yields a positive.
The caloric reduction makes the difference, as the paper notes:

> Of all the anti-aging and longevity-promoting interventions tested so far, calorie restriction (CR) seems to be the most conserved among species and robust. However, humans struggle to constantly achieve a certain level of CR. Here, we show in a clinical trial that a related intervention, alternate day fasting (ADF), also leads to striking reduction in overall calorie intake over the course of the study but is more easily tolerated than continuous CR and provokes similar beneficial changes

Aaand this is what happens when one comments before reading all the article...
From what I can see, Musk took tremendous risks with his wealth and time and is reaping rewards from it. It is one thing to be rewarded for your risks (good) — it is another thing to be rewards for other people’s risks and work.
I fast, on average, once a week. At least once a month, I try to do an extended fast (2-5 days) to force ketosis. I also do intermittent fasting basically daily (I only eat between 12-8). Been doing this for about 4 years now. Some anecdata:

- Fasting > 24 hrs paradoxically gives you an extreme boost of energy and mental focus. I especially love how my olfactory sense is extremely heightened. It's pretty cool and even after all these years doesn't get old.

- Fasting is not a panacea. Depriving yourself of nutrients or eating garbage is still a bad idea even if you fast or do IF. Unfortunately, eating healthy is hard and kinda' sucks. Egg whites and chicken + broccoli gets old pretty fast.

- Fasting >7 days is a bad idea unless you know what you're doing. This is when your muscles and vital organs start contributing as an energy source (e.g. they also start breaking down).

- Your body is clever, so extended fasts will start putting you into "starvation mode" and you'll lose some of the benefits.

- There have been NO STUDIES on long-term fasting (e.g. over the course of an adult lifetime). This is a big warning sign to just be careful and not overdo it. Different people have different tolerances. Talk to your doctor.

- Even on fast days, make sure you take vitamins (I take Fish Oil, Zinc, a Multivitamin and Magnesium)
You have a lot of balls to break the site rules while saying that.
What you suggest is what was followed by a large-scale distributed system I worked on. Your suggestion is also in-line with Google' SRE book section on Handling Overload: https://landing.google.com/sre/sre-book/chapters/handling-ov...

> Mandate that batch client jobs use a separate set of batch proxy backend tasks that do nothing but forward requests to the underlying backends and hand their responses back to the clients in a controlled way. Therefore, instead of "batch client → backend," you have "batch client → batch proxy → backend." In this case, when the very large job starts, only the batch proxy job suffers, shielding the actual backends (and higher-priority clients). Effectively, the batch proxy acts like a fuse. Another advantage of using the proxy is that it typically reduces the number of connections against the backend, which can improve the load balancing against the backend.

Other chapters on Load Balancing, Addressing Cascading Failures are related too.
It sounds like a weird case of the Peter principle - Levandowski might have been a good engineer, so good that he couldn't stay an engineer and had to try to climb up until he was directing the self-driving program. It sounds like he was worth a lot as an engineer, and worth negative dollars as an engineering director.
Welp, this article can't have come at a more appropriate time in my life. Definitely struggling with these exact thoughts, constantly. Finding something meaningful, and rewarding to be a part of has become obsessive. Always thinking I'm wasting time if I'm not somehow maximizing it, with the end result being I spend more time worrying about it than actually doing it.
It’s somewhat ironic that the biggest ever success-story in web-publishing, WordPress, reached early popularity because it had first-class support oob for two formats that declined a few years later: XHTML and RSS.
Thank you for the explanation. I'm still confused. So if a wire is wrapped in a specially crafted magnet, then when sending an electric pulse through it the pulse will "bounce back"?
The rules were probably set when China was a poor country like Fiji. They seem to have overtaken only in 2009. In 1980 GDP (nominal) per capita of Fiji was 6x China, now China is about 60% ahead. They've come up fast. (data https://en.wikipedia.org/wiki/List_of_countries_by_past_and_...)
In Brazil, the local mail charges R$ 15 (~US$ 4) to deliver international packages from "certain countries" i.e. China. The result is, ultra-cheap freight has almost disappeared, most sites like AliExpress now charge around US$ 4, but the class of this kind of package is not charged again here, so it is still kind of cheap.

OTOH mail from USA is damn expensive. I don't buy more things from USA because of this. And local customs tend to target USA packages more so the chance of paying import tax is way higher, too. Even packages from Europe and Japan are cheaper, and one can see they are more distant places.
I'd disagree in this space for their target market. They are targeting startups and many people that join startups like using new / cool tech. Also, most sales people I've talked to don't like the bloat of SalesForce, so I'd imagine they'd be cool with trying something new.

There are other reasons this will be tough, but I don't think this is one. The issue that comes to mind for me is integrations.
You might lose too much weight. Depending on your diet I could see it being hard to maintain a healthy weight on a lifelong regimen of ADF.
We also can't discount the placebo effect. That is, is it the caloric reduction, or the awareness that they are doing something presumed to be healthy. It wouldn't be the first time the body+mind was self-fulfilling.
I didn’t say he was sick. I was just recounting my observation. Was literally taken aback by how thin he was.

It’s different when you go on record as a public person in multiple interviews talking about extended fasting. People want to emulate influential people, whether it’s actually a healthy or unhealthy behavior for that individual.

Also, maybe Steve Jobs would still be alive today if we didn’t have this strange learned behavior to not say anything about someone’s health if we think something could be wrong? Something to think about.

Do you remember that article a couple years ago about pollution at the Port in LA? They've done a bunch to reduce ship emissions in dock but the truckers are popping up on the radar.

The short-haul truckers at the Port in LA are all independent owner-operators, which sounds like a cool libertarian/capitalist ideal until you figure out that new trucks are super expensive so the operators are almost exclusively buying used trucks, often quite old (and grandfathered into emissions rules). And as we all know from personal experience, there's a lot of soot that comes from a heavy diesel when it accelerates from a dead stop.

And there are no large necks to wring so now you're in the awkward situation of having to go after little guys.
> In my perfect world browsers have RSS support built in and aggregators like Facebook would allow RSS feeds to be published in timelines.
