Musk's aim was to increase boring speed by two orders of magnitude

The Boring Company FAQ only says 3x. They also want to do cutting and ring installation simultaneously, rather than alternately. TBMs have already been built which do that.

Here's the fastest TBM in current use.[1] Best month, 702 meters. Worst month, zero, when they hit a cavern and had to stop to fill it with gravel and grout before proceeding. Tunneling has surprises like that. That machine has both a hard-rock and a pressure-balance mode. Switching is a big deal, with lots of cutter changing.

One place Tesla might make progress is at the back end of the TBM. There's a huge amount of activity in back. Behind the TBM, there's usually a narrow gauge railroad track, and two tracks if there's room. Dirt cars are brought forward, filled with dirt, and sent back out. Ring segment cars bring ring segments forward. Work cars bring workers, tools, and spare parts. Track cars bring more track sections, to be laid behind the TBM. The TBM has machinery for laying track, loading and unloading cars, and moving cars from one track to the other.

What if all those work cars were self-driving battery-powered vehicles? Get rid of all the tracks, use self-driving vehicles with 4-wheel steering, and have them position themselves exactly where they're needed. Dirt cars stop under the output conveyor, fill, and leave. Segment cars maneuver into position
to where the segment assembly arm (a big robot arm) can remove the segments. No more track section cars.
You'd need vehicles which run well on the bottom of a round tube without being centered, so they can pass each other. That could eliminate about half the gear at the back end of the TBM.

Ask HN: Critical tech startup infrastructure setup experiences?
Hi all,

Before I start my technology company, I was hoping to get some insight into what critical infrastructure was necessary to setup for the business, and what, if anything, should be setup before beginning to build out product.

Were there any critical infrastructure components that took significant time to setup? If so, what were they and do you have any learnings you'd be willing to share to speed up the bootstrapping time? Were there any components that you regretted not setting up initially that came back to bite you in the ass?

I'm looking at components necessary for financial, legal, project management, software, logistical, system and development operations infrastructure and any infrastructure necessary to begin building an agile product as quickly as possible.

Thanks in advance!
Funnily enough I have a legitimate use for this: correcting GPS drift in a location with poor GPS availability. I would love to carry around a Raspberry Pi with an attached SDR that let me fine tune the signal so it's accurate versus showing me across the street, down the block or aimlessly wandering in circles.

Currently reading about Dunkirk because of the movie.

Interesting how the British told the French and Belgians to fight on while preparing and keeping their evacuation a secret. They even forced the French at gunpoint who wanted to defend Dunkirk to destroy their weapons. French who wanted to embark were shot at by the BEF - at the same time when French destroyers were helping the evacuation by fighting German E-boats. The BEF got away and the French fighting were captured. All RAF fighter squadrons were moved to the UK ahead of the evacuation.

It looks this was mostly by the BEF generals in France while Churchill wanted them to fight with the French.

Sahil, who's a HN user here, gets the credit for that minimalist payment form design. Gumroad is my payment processor.

It gets a lot right and allowed for product launch to happen about three months earlier than it would have otherwise. That said, email support for purchasing is occasionally required. Most folks get through it OK though.
Chinese here, I agree that it is very easy to have puns in Chinese. But I don't think Chinese find puns very humorous in general (probably it is too easy?), is it more often used to make blessing or satirical phrases.
Yes of course it is PR.

The thing people are wondering about is whether it is disingenuous bullshit PR.

Floppy things are hard to automate, and more expensive for less ROI.

This is off-topic but I figured I'd let you know: I flagged the post you linked, without coordination from others, for being derivative and lacking in any new content, perspectives or even a novel presentation.

I am sure that other people flagged it too.

I am not a big fan of this piece for its inaccuracy, but at least it brings some new subjects and perspectives so I can't find a reason to flag it other than my exhaustion with the subject (which is, of course, insufficient).

Why would you blame HN here? The post had 8 points on a midday Sunday.

If you put the word "unfit" in quotes then you are quoting the article. The first paragraph of the article says:

> The Google engineer who was fired last week over his memo wrote that most women were biologically unsuited to working in tech because they were more focused on “feelings and aesthetics than ideas” and had “a stronger interest in people rather than things.”

The article does not use the word unfit in the first or in any of the remaining paragraphs. Since you got that simple fact wrong I stopped reading your in-depth analysis right there.

Yes and no. It's true that collaboration is important when working on a team, and that social skills are underrated in engineering. On the other hand, the job is fundamentally not very social. Collaboration in engineering means breaking a large problem down into smaller pieces, and assigning those pieces to individual engineers to work on by themselves for hours or days at a time.

>> The funny thing is I have a wife and four kids so I am never alone, but painfully lonely.

> Not to be rude, but how can that be ?

I have heard this many times. A marriage can be lonely. A wife can also be your best friend. Chances are, you will feel both throughout the same marriage.

The same is true of friendship too. I have felt close and far away, pleased and angry, with the same friend at different times. That's how all relationships are. They are living things. They can be one thing one day, and different the next, all depending on what each of you do.

We seem to think that success in a relationship depends mostly on choosing the right person at the outset, and then the rest is automatic. If we choose the right person, a lifetime of effortless happiness. If we choose the wrong one, a lifetime of grief no matter how hard we try.

The truth is that relationships, like all living things, must be daily cultivated, by each of you. You can do everything right, but if the other person chooses to do bad things, the relationship will sour. That's the beauty and the terror of independent wills.

But why would we want that outcome? The Borg are universally despised on ST by all other sentient races, and assimilation is resisted whenever possible.

It's the same as arguing that the replicators on Stargate SG1 should be the logical outcome. Technologically, they are superior, but they're not a preferred outcome. Similarly, one could argue that gray goo or Carpenter's creature from The Thing are superior, but we don't want a world of gray goo or things.
> Silicon Valley culture encourages it. Google calls engineers who aren’t managers “individual contributors.” Technical skills are valued above soft skills or business skills. “Anyone who deals with a human being is considered less intelligent,” said Ellen Ullman, a software programmer and author of a new book, “Life in Code.” “You would think it would be the other way around, but the more your work is just talking to the machine, the more valuable it is.”

While I clearly don't think one should go to the extreme of undervaluing soft skills, can we at least keep one industry that primarily values technical competence? There is absolutely no shortage of other fields (most of them) where the main/only way to advance is through management, and I don't think this has to be treated as a flaw that needs to be fixed.

> Then the 3am phone calls will start...

As a developer this is exactly what I want. It is part of having ownership and is critical to writing and maintaining good software. Containers are great for this reason as they give me control of the complete runtime environment of my application so I can better support it.

And it makes those 3am calls less frequent, not more. I've always been on call for my software and I thought this was now the norm and the throw-it-over-the-wall process had mostly died out.

I totally applaud 1blue3brown's videos but for some reason, his approach leaves me more confused than ever. Long winded unnecessary visualizations, especially when animated, annoys me for a reason that I cannot explain.

Don't get me wrong, visualizations are powerful but I think I prefer static visualizations. Animations overload the visual system with "visual bloat", if you will.

Also, this video did not help me visualize higher dimensions. I prefer a simpler approach - just project down to 3 dimensions (or 4 if you add time at the risk of animating).

If you want to utterly destroy social networking as a product category, why attack it in such a roundabout way?

This would destroy social networking. If you live in the same geographical region as someone, Facebook is adding little value to your interactions. Maintaining relationships between people who are too far away to interact regularly in person is kind of the point.
Recruiters could at least ask coders what coders are interested in. I get a few emails per month from recruiters/CEO's and they are invariably doing the same mistake: they enthusiastically describe their product but not what I'm interested in: tech stack, new/old code, office location, team size, role/responsibilities...

I don't care what the product is if the tech stack is wrong, and with the right tech stack and other circumstances I can work on any product.
I agree completely. Back in the 8086 days, Boyer Moore string search delivered significant speed up over linear memory scan, but nowadays nothing practically beats SIMD linear scans except in very specialized situations.
So if I understand the wikipedia artcle about Hokkaido characters, they are not out-and-out fakes, the seem really to have been used by Ainu people, or by other who lived in the same area. But that there is argument about who used them, when and what the inscriptoins mean. Also suspiciously little info on the wiki page about how old the artificats are.
I'd read it.
Yea, I have a lot less faith in the explicitly-unethical Facebook and its leadership than in Google, and that's been the case pretty much since Facebook came on the scene.

But how principled the founders are is only one part of the picture, and Google just has the potential to be a lot scarier. People change, companies outlive tight control by individual people, and explicitly-evil actors with armies force companies to do things or compromise their systems (this already happened to some degree a few years ago).

I don't really understand why HN goes on and on about how social media is inevitable and you're just a victim of its use. It's pretty easy to drop Facebook and pay a pretty trivial cost. Avoiding Google products, on the other hand, requires a sustained attempt in a dozen different product areas to use usually-inferior products. It's not impossible, but you pay a fairly hefty cost, to the point that most people don't bother. As you mention, they also have a lot finer grained data about what you actually do, as opposed to Facebook mostly knowing what you care to share.

Because that's the pattern I noticed in the last few days (or maybe I missed the good discussions that were had previously of which this is a repeat?). For example, as I pointed out here: https://news.ycombinator.com/item?id=14997068

> Yesterday, this had 156 and 101 comments points after 4 hours, and had been sunk like a brick to place 46 on page two

(which I now realize should have read "156 points and 101 comments")

How about flagging things that absolutely don't belong on the site, and simply not upvoting things you don't find very good?

edit: I mean, especially in the context of a guy writing a memo the "larger point" of which is to not silence people who aren't ultra-aligned, to have free discourse about ideas and how to make Google and the situation for women at Google better, getting fired for that and then HN being filled with people distorting what he wrote, while "journalists" do the same. And yes, it's getting upvotes, too, people do want to discuss it, it's just that others don't want to let them.

This is an outright attack. This is another move of sociopath social engineers testing the limits of what they can get away with, and just like with Appelbaum, HN fucking FAILS. It's not about "content", at most about the content of the personalities of the people involved.

It's relatively harmless and in good fun. Saying there is nothing there betrays ignorance on the source material. If anything I'm prone to believe some of the conspirators are behind the dissemination of the theories, if only to draw a little attention and recognition from a largely disinterested general public.

I feel the writer is either being disingenuous or isn't a professional in the field.

As a software engineer myself I do agree that collaboration is essential for the product development cycle, specifically it's important for training hires and for project planning, including breaking down features into tasks. That said, once we make it into the task level, where coding gets done, the job is absolutely a solo task. That's what the whole process is designed to do; to break down any requirements into tasks that can be worked on solo by one team member, at that level collaboration or anything other than technical skills don't offer much.

That says nothing at all about what is under the topsoil.
The essence of the problem is this: 'tech' is now simply too big and too important to our culture and society to be only about the technology.

Now, decisions made at Google don't just change how we search the internet.

Now, decisions made at Uber don't just change car hire.

Now, decisions made at Amazon don't just change online book selling.

Technical competence is essential for competition and innovation, but social competence (and conscience) are essential to growth and longevity.

I've logged into Facebook in incognito mode for the last decade. It's really not that difficult to avoid doing this. By contrast, I might visit a dozen different Google services over the course of the day, their apps are a lot more indispensable (mobile web Maps is no fun), etc so it's a lot higher effort to do so for them.
You are right that we can not make a perfectly quantifiable experiment to check the rate of innovation in a "purely Free, RMS-style" world vs the current one where proprietary software is also allowed.

But using that as an excuse to keep believing that "we could have gotten where we are only with Free Software" is a cop-out. We don't need to have an alternate timeline. We can think of our existing one as the (non-linear) superposition of two competing philosophies and their development: the hobbyist/academic/free one & the commercial/private/proprietary/profit-motive-based
one on the other. We can surely come up with some kind of model to see how the "free economy" would fare if there was no "proprietary" agent.

You have said it yourself: there was a revolution going on, but it was only affecting the hobbyists, the enthusiasts. It took the "proprietary" side to exist to make it computing something as universal as it has become.

Without proprietary software, there would be no BSD 4.4, Linus would not have anything to clone for the PC, there would be no Free/Open/NetBSD, and so on.

Remove these from the "software economy" of today, and what would we have? Minix? HURD? "Innovative", alright. But certainly never able to compete with the proprietary (or proprietary-clones) alternatives at any point in time.

1. Try applying to an embedded programming job. Or a dozen, better yet.

2. Take an "adjacent" job. I.e. find company that has both embedded jobs and non-embedded jobs; apply for the latter. It's easier to transfer within a company, because they know you and say "oh, psyc is smart, he/she can learn this" as opposed to "who is this psyc person? they don't know embedded". So it's a good way to get into jobs you can't otherwise get.
The most profitable software company ever still can't build software properly (meaning: fully documented). Does this mean that it is impossible to build software properly at scale? Or is it just that you don't become that profitable without cutting a few corners?

(In my original comment I said "most profitable company", but it seems the dutch east india company gave them a run for their money. So, good news for apple, they still have room to grow.)
They said 'if you're not using the value', and you've presented an example where they are using the value, so you're criticism doesn't apply in the case they're talking about.
