Ask HN: How would you bootstrap a telco?
I'm based in Vancouver, work remotely for a global company, and the outage yesterday was a huge pain in the butt for myself and many Canadians I work with... I am appalled that 911 services weren't even working in some cases.

The telcos here are terrible. I'd love to hear how HN users would think of bootstrapping a telco?

We've had a few startups try and disrupt things in Canada (e.g., Wind Mobile). They were funded by large global investment groups and eventually simply got acquired by the incumbent telcos.

The other approach I've seen is piggybacking on existing telco infrastructure. This is required by law since the Canadian government subsidizes telco infrastructure... It's not uncommon for the telcos to renege on their contractual/legal obligations. Plus, this doesn't create any redundant networks.

So: how else can one launch a telco? What creative solutions have folks seen?

I'm thinking: VOIP-only service that has direct access to the Internet backbone in Toronto, Vancouver, etc. so you can at least have completely separate service in major cities... Or crowdfunding 5G towers (though I imagine spectrum licensing is an issue here).

Would love to hear what other HN readers think.

One of my favourite course I took when studying physics at university was “Biological Nanomachines”. I find it absolutely bizarre that trying to gain a physical intuition for biology is not the norm. Throughout school I hated biology because it really did just feel like rote learning. This is embarrassing but I had such a poor understanding of what a cell was by the end of HS biology that I still had an image in my mind of a little conscious being that makes choices: “the cell wants to x” is language that we can’t use in a HS classroom
During the first part of the pandemic I watched the lectures for the Introductory Biology course [1] from MIT OpenCourseWare. I cannot recommend those highly enough!

Almost every lecture brought up and highlighted something really cool and fascinating. Like how RNA sequencing over the last couple of years has gone from expensive to almost free, and what its uses are. Or time-lapse of bacteria adapting to antibiotics. Or just the first lecture showing a video of someone sticking a syringe into a cell. There were even some labs that could be done via a normal web browser.

For me this was so much more engaging than the biology I was thought in high school, where we mostly learned things from outdated books.

"Everywhere you look—the compiler, the shell, the CPU, the DOM—is an abstraction hiding lifetimes of work. Biology is like this, just much, much worse, because living systems aren’t intentionally designed. It’s all a big slop of global mutable state".

Brings me to wonder, could we ever create anything so marvellous as what biology does so effortlessly.
Is the example on the programming fonts site correct? It looks like there are spacing issues to me. Look at "removeChildren". The "remove" part the letters are pretty much evenly spaced. The "Children" part looks like there is more of a gap between letters.
If it was limited to my own company, I’d definitely blame it on our culture. But so far, based on discussions with a few dozen friends and colleagues, everyone seems to be missing the in-person interaction while not missing the commute. The general consensus wants a hybrid setup with a few days from home and few days from office.

As for why tenured engineers left, they all had spent 3-5 years in this company and it was time to move on just like any other shop in tech. That seems in line with overall tech sector.

And it is borderline impossible to build camaraderie or a well bonded team purely online without any in person interaction for months or years. If you think you have seen that, please share further details about what worked and the name of the company. I am very much interested in learning how to build great teams online. So far, outcomes from even the best practices don’t seem to hold a candle when compared against the in-office experience.

That is 1%, not .1%
> the track pitch

I think the term you're looking for is track gauge.

And as for a need to widen it in curves, the answer is basically it depends.

On mainline railways gauge widening in curves basically stems from the days of steam locomotives, which mostly didn't have bogies (at least for the main driving wheels) and comparatively enormous wheelbases.

On straight(ish) track, some minor gauge widening as compared to the nominal standard gauge might nowadays also be beneficial, especially on high speed lines.

Within the context of streetcars/trams, which often need to negotiate very tight curves on the other hand, current state of the art seems to indicate that a slight gauge tightening might actually be more beneficial in order to avoid too large a skew angle between the bogies and the rails. (Compare http://interfacejournal.com/archives/472)

I'm no wheel/rail-interface guru, so quite what the conclusions from that would be for BART I can't say, either, but just wanted to point out that the topic is somewhat more complex, and nowadays gauge widening in curves might not actually always be the right answer.
Gold is much less volatile than BTC and seems like a better inflation hedge. I don't expect to buy things with gold directly, but I can invest in a gold ETF such as GLD, and I can easily convert GLD to cash by selling.
I don't remember seeing much about Jane Morris when I visited the William Morris Gallery[1]. I didn't leave the place wondering about their (somewhat open) relationship.

Apparently, the book that the article is about will be discussed in a talk at the gallery later this month[2].

[1] - the Gallery is one of London's hidden treasures, in Walthamstow. The accompanying website is nicely done: https://www.wmgallery.org.uk/

I guess I'm the foolish one, but I thought the title implied that the book was about algorithms you can use to make decisions, not decision making algorithms.

Well, the M1 is great (I like mine, even if it took 6 months to arrive...), but my comment stands for older versions of the MBP with Intel inside.
This really is a situation that's almost too big to fail. Let me explain.

First, since so many voters are invested in the housing market, it's almost political suicide to do anything about it now. Protection and even increasing property prices has become an explicit political goal on every level.

Second, as you see more and more corporations enter this market and become stakeholders, this trend is only strengthened as corporations are the true constituents. And no it doesn't matter which party is in power. The corporations have bought both of them.

I'd say the biggest difference between now and 30+ years ago is the level of disposable income people have such that second homes, vacation homes and bigger homes have become way more common.

1. Gold will never go out of circulation. It‘s the commodity with the „longest“ track record.

2. The price of gold is highly manipulated, like everything else. You can‘t tell how much is produced each day, or how much is in circulation. Gold will always exist and will always have a „price“.

3. BTC could be part of the store of value story, but then again, it will always be manipulated (by governments, trading firms etc)

You can‘t calculate or foresee price of material which is in demand. Look at oil. It „should“ be so much higher, but other people say no, since there is an abundance of oil still in storage.

If things are getting BIG (like oil, Gold, maybe BTC), the price will become political and therefore not be able to calculate.
Lovely life lesson shared. It also blew my mind how much complexity handling non formal, discrete systems adds. Just samoling root development takes years and endless hours of tedious, non automatable work. No wonder the field progresses orders of magnitudes slower. Also, add chaos theory, quantum mechanics, differential equations and enzyme molecules to the distributed system to make it a bit more realistic.
Yeah, I was kind of making a joke. But to stretch the analogy...

No, because any time a company shows up that could pose an actual challenge to their stranglehold, all 3 companies gang up and lobby against them.

How about we also include how MS infiltrated the education system with hidden incentives and essentially forced training in a non-free user hostile operating system to multiple genrations of people?

I think people had to learn Windows. They can learn Linux. The excuses are bs. Schools should teach unix/linux, and not proprietary systems. We should expect people to learn new things to be able to operate new tools. Thats ok to expect. This idea that the computer is a dumb terminal is far too prevelant thanks to phone and tablet proliferation, another tech corrupted at the outset to be user-hostile and spy on them.

Desktop linix and laptop linux are 99% of the way there. Yes, you will have to learn new commands and ways of doing things. Yes, some software you are used to won't work (wine be praised).

It's worth all the trouble though. Freedom isn't free, you have to actively persue it.

I look around and see way too much Stockholm Syndrome going on.

What happened to Gold when Nixon closed the "Gold Window" in 1971? It didn't magically become worthless... what happened instead is that the US Dollar lost most of it's value. The only think keeping it alive is the PetroDollar system instituted by Nixon and Kissinger.

I fail to see how BTC can possibly devalue gold. If the dollar were to further slide in value, if people magically started using BTC instead... the Dollar price of Gold would simply go up even more.

>it seems like the gold that’s used for financial trading could go out of circulation.

Yes, it's been sitting in vaults for decades, that wouldn't change.
Can you name one thing that a NOOB-friendly Linux requires the command line for that a technically illiterate user can accomplish in MacOS / Windows?

What does that mean? I've run Linux on all the MacBooks I've owned. I just ordered an M2 Air with the intention of using it primarily as a Linux laptop.
Honestly most of the reason I like a big touchpad is gestures. On mac especially. Switching desktops is 3 fingers to the side. My fingers aren't that small, it's a lot easier to do it on a big trackpad. I never really practiced with a track point when I had one, so I was maddeningly imprecise. Having a big touch pad lets me have more room for error on cursor movement. To do that I have to move my hand slightly more to get to the center of the pad. As you said it's subjective.
It's hard to argue against that logic... the Arch Druids can't have it both ways.

How would we know if we’d made this progress? How do you know if any other person other than yourself is conscious? (I think this is called the “zombie problem”.)
The good news is that some of this is publication bias, not a devolution of public mental health. Before about 1960, the lower classes had almost no chance of getting their words into the written record. Did 7th-century serfs see themselves as oppressed and miserable, or did they love their masters? We don't know; we have no record of what they actually thought.

Therefore, we aren't necessarily in uncharted territory when it comes to lousy public mental health; it's possible that we were worse off in the 1930s and '40s and wouldn't know it by the data, because the most put-upon and miserable people weren't writing at all.

This doesn't explain the uptick since 1980. Moreover, since then, publishing (at least, traditional publishing) has reversed the changes of the midcentury and returned to being elite and exclusionary (albeit, in a different way) and yet we haven't seen this sort of censorship effect (and, to be honest, I'm glad we haven't, simply because I'm no fan of censorship). This establishes with high confidence that public mental health has worsened at least in the past 40 years (which, let's be honest, we didn't need a study to prove) and that--perhaps unusually, by historical standards--the middle and upper-middle classes are as miserable as everyone else, a fact that to me makes a strong argument for the Marxist framework in which only two social classes--the owning bourgeoisie, and the working proletariat--actually matter (since Marx did not deny a middle class's existence; he merely chose not to focus on it, believing--correctly, present conditions suggest--it to be an innately unstable status).

Misery isn't new. Oppression isn't new. War and poverty certainly aren't new. What is happening on an unprecedented scale is the re-proletarianization of people (the West's former middle class, no longer needed in such number due to the end of the Cold War) who thought themselves to be part of the bourgeoisie--who believed their educational credentials and professional networks (paper armor, it turns out) were "as good as" actually having capital. Wrong, it turns out. Such people can be making $200k/year one day and forced to do Scrum the next; and we're all one medical emergency away from ruin. The collapse of a middle class isn't nearly as bad a calamity as what nature and history have thrown at the poor, but it is the kind of disaster one hears about.
That may be the first case I've seen of anti-black snarky racism being thrown at an obviously very white guy. Very interesting trolling specimen there.
Can you name a few?
i keep most windows in fullscreen and use the expose function or how it's called that shows all windows in reduced size to switch. sometimes i put two or three windows side by side if i need to see them at the same time.

i also make use of multiple workspaces/desktops to arrange windows that are related to each other.

so i use the maximize function but never feel the need to minimize windows unless it's a window that i don't need to reopen ever.
It seems like the larger argument here (which I wholeheartedly agree with) is that the role of skilled teacher (whether it be human, book, YouTube, whatever) simply cannot be understated when it comes to creating that “spark” in a learner to develop and pursue their own passions.

What’s interesting to me, and what follows from this, I think, is that we therefore have a lever for creating more passionate people: create more extremely skilled teachers.

It’s obvious to me that this idea isn’t new; I just wonder why it’s so deprioritized at almost every level of education. (Not least the highest.)

My normal London-Stoke train is 145.9 miles in 1h28, average of 99.4mph, with 125mph along great swathes of it.

The hourly Glasgow departure averages 105mph to Warrington

Once you get up north speeds drop -- the eng to end average for Glasgow-London is about 84mph (401 miles in 4h47), Edinburgh-London is a similar distance but a bit faster at about 4h26, so 89mph.

Washington DC to Boston is 440 miles and seems to take about 6h40 at best, just 66mph
Perhaps I’m just not seeing the benefit. You can absolutely have friendly, polite, cordial colleagues remote/over Zoom without being friends, no? In the decade I’ve been remote, across several orgs, this has been my experience. Friendly but not friends.

A friend is someone I can expect to be there when I ask for or need personal help (and vice versa), not someone who shares their beer or hobby preferences over a Zoom 1:1. Deep bonds are forged in meaningful shared struggle (see military bootcamp for an example, where you are broken down and built back up together), not ephemeral employment.
OSX can have multiple desktops too. in fact the way i arrange windows on gnome vs OSX is pretty much the same.

For an emergency I personally would disregard FCC regs. I don't think the rescuers will care either. Certainly local law enforcement won't care. Out in the wilderness it is unlikely one will be causing interference using a few extra watts. I say this as someone who used to pump out a few thousand extra watts. People generally get into trouble when they are playing around on frequencies they should not be on and causing interference, especially with businesses or law enforcement. Prolonged interference is what draws the attention of the FCC via complaints, usually because of harmonics from cheap radios. I should add that the FCC are few in number and spread very thin. It is extremely difficult to get them to respond to interference complaints unless the complainant are a big business.
OT: that reminds me of an interesting physics problem.

If you have a ball sitting on the floor in the aisle of a stationary bus and the bus starts accelerating forward the ball rolls toward the back of the bus. If you have a bus moving at a constant velocity and it start decelerating the ball rolls toward the front of the bus.

Suppose you also have a helium balloon floating in the bus. Does it also move toward the back of the bus when the bus accelerates and toward the front when the bus decelerates? Or does it stay where it is? Or does it move toward the front when the bus accelerates and toward the back when the bus decelerates?
Wikimedia's statistics tools for its wikis includes a bubble chart of number of edits by a user per hour of day per day of week[1] (AFAICT a type of graph called a punchcard chart), used precisely for when you wonder this about a Wikimedia user.

That and other detailed statistics are only shown for users who opt in, but anyone motivated can process a database dump locally, even using XTools itself, which is open source. Edit history can reveal a lot of information about a user, so this an inevitable privacy problem for any scrapable site.

Nope. I spend one third of my life at work and I’d rather spend it with people I trust and I have a friendly relationship with (doesn’t mean they have to be my friends), rather than a robotic transactional environment.
