It's really hard to measure these things because there's so much nuance in every investment decision.

One interesting artifact from the abstract though: there is no such thing really as 'Female Dominated Industries'.

While there are industries which are mostly male, even in tech, management and above is very male ... supposedly 'female industries' are not as lop-sided. In fashion and cosmetics there are tons of men. Though in early-childhood education it may be very female at the instructor level, it most certainly is not for companies that develop products and services in that industry.

So not to discount the sentiment, rather to say 'it's hard'.
I do care. uring mentioned by others, btrfs changes, bcachefs foundation work, anything tracing related, etc are interesting to me.

The whole tracing story in Linux has changed in the recent years. It's really useful in practice.
That’s why you would need an agent. Yes Facebook will brush it off if a random hacker anonymously contacts them, but if they’re approached by serious man in a suit with experience in the field, they’ll take it seriously, and, if not, you hire a social media expert to kick up a big fuss
I don't know what the data say, but I wouldn't be surprised of they do nothing.

I don't understand what change the sharrow gets people ready for. It just states a fact that was always true (there might be bikes here). Maybe it makes it front of mind?

When I'm biking, I interpret a lot of sharrows as "bikes, get your butt to this specific location", which can make me more afraid of other drivers if I use the road in another way that might come more naturally to me.
Having worked on a military base for years, they will go into a state of high alert over next to nothing. I think installation commanders simply figure that since everyone affected has already agreed to be part of a military installation with the ups and downs that brings, it's fine to err on the side of caution and activate security procedures for anything that comes up. It can be mildly annoying when you find out you're locked in because someone found something suspicious somewhere, but hey, you're working with the military. For the military, behaving as if they are under attack is part and parcel of the organization.

You don't alert the press until you're pretty damn sure, though. Military bases can already have stressed relationships with their communities and they don't need to be starting a panic over every change in the FPCON.
I was working at a fairly small company who tried to do the whole 20% thing. For me it was awesome as I got to work on some really valuable things without all of the bureaucracy around project management.

For the more junior folk though it seemed like a waste of time as their stuff seemed more fun than valuable to the company.

At Google/Atlassian is it entirely 20% on what you want or do you first need to propose and justify the value of the work you plan to do with an approval?
Changes from one release to the next probably won't matter very much to most individual users, unless something specific you're using is getting support added, but you'll usually find at least one or two major features between LTS releases, including stuff that impacts ecosystems beyond just GNU systems.

Wireguard and exFAT are a couple of notable ones that have been mainlined since 5.4, with the latter impacting basically anything that uses SD cards (as it's a required part of the SDXC spec)
Cheap and Higher 3D Printing Resin – Weistek3d.com
So you believe everyone has perfect control over their own choices, actions, reaction, faculties, in the face of all the overt and hidden influences that others seek to have upon them?
Weistek3d is a 3D printing company established in 2011, mainly marketing 3D printing equipment and accessories, such as UV resin, LCD resin, Filaments, and other parts. Among them, UV LCD resin has very high popularity.
I guess you can have a distributed locking mechanism, either scope or line-driven.

Another option would be when there is a conflict you have a fork, and then re-merge at a later point (eg. when scope-specific changes are complete or scope is left or syntax is re-evaluated as valid), more similar to git style workflow. Which begs the question, why not just use an established RCS/VCS like git and build the interface in front of it, utilizing its built-in diff? However, this workflow probably detracts greatly from the real time intent...
I assume the high value is more about Tesla being more than a car company.

1) If they win the self driving race that will be incredible value beyond just manufacturing cars.

2) Battery manufacturing in general is huge on its own.

3) The roof top combined with domestic battery side is potentially significant in replacing (full or part?) domestic power companies

4) Insurance - Musk said this could grow into 30-40% of their business

5) Super charger network gives them a first advantage to replace petrol stations to a degree.

6) Elon factor of what's next.

And dont get me wrong, I do feel its gone beyond reasonable value, but there is more than a car company there.
Yeah, only the inference chips are in production in the car.

They have a chip team in Austin which is lead by Pete Bannon, formerly of PA Semi (which Apple acquired to build their A series chips, and now their M series chips). The chips they designed are fabricated by Samsung in Austin.

The "FSD Computer" that they have in their cars now has an Intel Atom board to run the user interface, and then dual arm SoCs to run the Autopilot stack. Each arm SoC has a special ASIC to hardware accelerate certain common neural net inference functions (I.e. dot products and other matrix math).
I absolutely understand what the speed limit is. And understand that in most jurisdictions it is perfectly legal to go under the speed limit, however that makes it no less annoying. When you are following someone in a car going incredibly slow are you not annoyed? You want to pass them, but you don't want to do so unsafely, so you have to wait for a safe opportunity the whole time just wishing they would go the posted speed limit. Then someone behind you gets even more impatient and passes both of you creating an unsafe environment for everyone.
They are working on training chip as well codenamed Dojo. Elon is thinking of offering it as a cloud service, just like Google’s TPU service.

The stock price is built on the expectation that the 0.7% is going to quickly grow to a lot more.

If that expectation holds, the current high price may be sustainable. If it becomes clear that it won’t, there will be a big sell-off
I absolutely loved Mythic Quest, but if it didn’t grab you after the first episode, then it’s just not your cup of tea.
I’m curious what motivated you to leave a big tech company for a small one?
I choose to believe it is.

Then again I can name at least one person who would unironically agree with what the GP has written.
Linux 5.10: Many Changes, from Better CPU Support to File-System Optimizations
This. It still seems like other carmakers are not taking EVs seriously, and are content to milk ICE vehicles to the very end.
No, he’s not.
Completely agree. Btw, the abov example wasn’t my company. The CEO just didn’t want to spend. He was also a huge proponent of building everything in-house so we ended up tons of customized software that nobody knew how it ran when people started to leave. The company’s growth eventually stalled and was acquired. Shame because we had some brilliant engineers.
Coffee History Myths and Reality
Historians failed to reach a consensus about when and where coffee was discovered.
I wouldn't count out Toyota just holding for the right market forces. Go car shopping today and you quickly realize Toyota has some of the most sophisticated technology on the road already.

Their entire product line is available in hybrids with a low speed EV mode. Most of their competitors don't seem to be offering hybrids of larger vehicles like SUVs. But if you need a third row seat car that gets 50% better gas mileage than anything else in it's class... Toyota can sell you one.

I suspect the only reason they aren't selling full EVs is that the number of people willing to shell out for them is still so small.

They needed a tool, they created the tool which did what they wanted, but at high cost in terms of highly skilled and experienced manpower.

Don't we do this all the time in IT thought? Big issues in SW, which we plug with people's knowledge, time and experience? Isn't that what they were/are doing here?

I only have the utmost respect for these pioneers, literally taking their lives in their own hands...
(I'm the eponymous 'Johnny'.)

Symlinks can work, and I've used them.

My advice to people is usually, though, that your brain will sort it out for you. And it really does.

The canonical example is "home insurance". Say you have a category of "home" and a category elsewhere of "insurance". Perfectly possible.

Which one does it go in? Well, you designed this system. Your brain came up with it. I've found that in nearly all cases, you just know.

I see where this may fall down in a shared environment (work), which is why I advocate (in one of the many unwritten posts on my as-yet-to-exist blog) for the role of a 'librarian' at work. We seem to think that 20 people can work on a project together and all just magically decide where everything goes. That has been shown again and again to be a fallacy that we believe search will help us with. My argument -- from experience -- is that it does not, and that we need to go back to a world where we organise things, and that people are responsible for this organisation.
When I'm on a bike, I honestly don't feel safe taking up the entire lane. I guess in theory the expectation is that cars will calmly drive behind my slow bike until there is room to pass, however long that may be, but I know that people are going to get impatient, and that just makes it feel less safe, or inappropriate. I feel like at any second I'm going to get startled by a loud car horn right behind me, which is very distracting.

So for me the sharrows do make a difference, since they make it feel safe to use more of the road, which makes me do it.
Presumed sexism in the wider market doesn’t mean actual sexism should take place during funding.

It’s not a question of whether it’s priced in, it’s about giving everyone the same starting line.

This was a really thoughtless comment in my opinion
If a company is investing in non-synergistic assets with excess cash, why not just instead convert that cash to shareholder profits?
I can't believe this comment ended up dead - that was the correct answer. I had more success with ddd this time around.
Those are functions of a Post-Sale role or a Customer Success role, and very often, you see them doing training to customers. In my past job, that was the primary function of the customer success team.

The team asked me a few times to explain technical updates and particular concepts to them to "rephrase" this explanation to the end customers. They either make 1-1 call with the clients pushing "informal" training or prepare text content that they forward by mail to the clients; they also did webinars. Still, they were more familiar to made calls. I know they have a common phrase to start, something like: "Did you know you could do X "faster/better" by using Y from software," all of this to make sure the customers receive constant training into using our software. I understand that principle or the intention here is that when the customer is well trained and uses the software at his full potential, it's better retained and more valuable.

Your friend looks like it will be great in a Customer Success role; you could even open it up to pre and post-sale functions. Allow him to create content to train your customers, communicate to the customers to get feedback, and push better training and understanding of your product. The goal is to maximize retention and increase conversion to post-sales.
Seconding the recommendation for getting "task glasses". It is probably the single most impactful change one can make.

I ordered a pair (via Zenni, just some regular polycarbonate lenses) that are at just the right optical power such that if I fully relax my eyes, objects 1 metre away are in focus. When my monitor is that far away, it's at optical infinity and very comfortable to look at for long stretches. It's a very noticeable difference: on the occasions that I forgot to put the task glasses on and wear my normal glasses by mistake, my eyes almost always end up feeling sore after a few hours.

I'm tempted to get another pair at 50 cm for laptop and phone use.

Yep, a friend of mine named it in 'honour' of Dewey Decimal. Kinda genius, which I can say because that wasn't my idea. :-)

Home Lab: The Idea
Most likely the entire story was fiction.
Same here. I think most of the logistical overhead of a traditional small restaurant will be commoditized and abstracted away by cloud kitchen providers, a marketing/rewards layer, and delivery companies. The barriers to entry will come down, but competition will increase and margins may decrease. We'll be left with fewer "restauranteurs" and more chefs who can sit in the cockpit and simply plan and execute on menus. Since physical location is no longer a moat and menus are easily replicated, they will have to compete and win on brand. It will be interesting to see the margins on delivery-only versus indoor dining once the pandemic is behind us.
I think of 20% time as error correction for management. Engineers can route 20% of their time to what they think is important, and not what management thinks.
Nobody from management told me to rewrite the primitive array handling in the proto libraries for Java. It just irritated me that they didn't do what I thought they should, so I spent some time fixing it.
A very common source of information to reporters are people who aren't authorized to speak about an issue, or people who have informal relationships with the press and don't want their names revealed publicly.

There are indeed many good reasons why specific people aren't cited in these articles, but who you're trusting is the Washington Post, not these individuals. The trust comes from what the Washington Post does when it finds out it has published false information, and its track record of making sure what it publishes as news is accurate, or corrected when discovered to be false.

As a overly generic rule, trust (or don't) the Institution over the individuals.

What's your point? Market cap is a forward looking measure of perceived future revenues and profitability, for which their current situation and the overall markets they're in are very relevant (not to mention very much relevantly for TSLA, expectations of how well they can execute).
In Pictures: How much plastic are you eating?
My hypothesis is different.

Margins.

GM, Ford, Honda, Toyota, etc. are competing with a commodity product in a commodity market. There's no big difference between a Toyota Yaris, a Honda Fit, a Kia Rio, a Ford Fiesta, and similar cars from every other brand.

They're all within a few hundred bucks of $15k. They all cost do the same thing, cost the same to produce, and I imagine the margins are razor-thin. If any of the brand could lower prices by $500, they'd own the market.

Tesla sells a unique product, with unique technologies.

If Tesla has 5% of the market, but 10x the margins of its competitors, which doesn't seem an unlikely outcome:

1) Its profits will be roughly 1/3 of the total profits of the whole market

2) It will be much more stable. Razor-thin margins mean companies go bankrupt with even minor instability. If Ford's costs rise by 5%, it's dead. If Tesla's costs go up 5%, it's a almost a rounding error.

I think the key question is whether Tesla can execute, but right now, things look promising, although far from certain.
The vibrancy of open source projects/products
Back in April during the early pandemic dip, I bought some shares in Tesla and watched them skyrocket. Sold a good chunk of the shares and watched them double again. I owned Tesla previously at around $200/ share and regrettably sold those shares.

Tesla is tough to value, but I hang onto my shares for a few reasons.

#1 I've profited enough that I've been able to cash out my original stake. Right now any investment in Tesla is house money.

#2 Tesla is in a fairly unique position to gain from a lot of strong trends right now. Electric cars are just part of it. Tesla has their hands in a lot of the technology required for green power. Energy storage, solar, Tesla has their hands in it all. We're at the beginning of the curve on almost all of these technologies and Tesla has a pretty strong competitive advantage.

#3 Elon Musk. I'm not a fan of many of the things he says and does, but he seems to have a talent for coming out on top and being ahead of the technology curve. I would honestly prefer owning SpaceX to Tesla, but since Tesla is the only Musk company which is public, I'm content with a piece of it.

#4 Cars. The idea that VW/ GM/ Ford would leap frog Tesla once they started competing hasn't happened. Almost all the Tesla competitors either have far lower ranges, higher prices, or sometimes both.

I have no idea if Tesla is worth 1/3 of what the rest of the auto industry is worth. But a giant chunk of auto industry infrastructure is going to be obsolete within the next 30 years even as Tesla is perched to continue growing so perhaps this isn't too odd.
You are arguing against a different idea than was presented.
> I believed for a long time that 'else' was just a shorter alternative for 'otherwise'.

It has other uses, but it is that (that is, “or else” is exactly that, and, among other uses, “else” by itself is an accepted short form of “or else”.)
Apple has a great incentive to continue allowing general computing: a significant portion of their users will stop buying their computers if they do this.

Almost every developer I know will stop using macs if macs start actually preventing them from running whatever software they want.
Your complaint is confusing. "Enter a lane with a vehicle"? As in, be on the road while vehicles are on the road?

It sounds as if you think, if there is no dedicated bike lane, that bicyclists shouldn't exist.

In many places, legally, vehicles have no more right to the road than bicycles. The "road" is a shared lane for bicyclists and vehicles.

That it is dangerous is the responsibility of all to mitigate, but the multi-ton steel box has the obligation to yield.

Ask HN: How to not waste time throughout the day?
There are those equipped with the ability to not waste time. By wasting time I mean using their time to either gain more knowledge and to better themselves. For example, I would like to study subjects x, y, and z throughout the day. But my inability to focus on the task prevents me from advancing in subject x, let alone y and z.

What are techniques you use to not waste time? I have tried the pomodoro technique, but the five minute break turns into an hour break, and so on. It may be that I am spreading myself too thin trying to learn so many various different things, that it overwhelms my mind and the mind retaliates by doing nothing.

I believe this is an important topic for many people, especially in the HN community. Many aspire to accomplish lofty goals, but the giant obstacle is time. If only we could not waste our time, and work on that side project one was always wanting to do, or study that subject you always wanted to know more about.
To be fair you have the burden of proof by asserting "computers connected to the internet can not be secured."
The other auto makers will make electrics cars and people will buy them.

The magic ingredients at Tesla are just not that magic.
(I'm the eponymous 'Johnny'.)

Yep, and the numbers tie things together across disparate systems, e.g. your file system and your to-do system.

So I have a project, `12.34 Whatever`, and it has some files in the file system. I also have an OmniFocus project named the same. And an email folder.

It's real easy to line those things up together when you want to work on that thing.
What's wrong with my rhetorical style?
Lie Detection by Strategy Manipulation
Most of the big automakers make far more than just cars. GM has a defense division. Honda makes a business jet. Hyundai builds ships. Detroit Diesel was owned by GM, then Daimler, and now Rolls-Royce.

Anecdotal but I pushed this number to the limit with 5 kids (went for a 4th and had twins). Our pediatrician said (subjectively of course) that she found her happiest families had 4 or more kids. Not sure why that would be the case, but we are certainly a happy bunch.

Yep, this can be an issue. See my sibling comment here:

Not in civil liability suits, which is what these rules seem to describe, only in criminal cases.
The VCs are not inclined, obligated, or interested in "giving everyone the same starting line." They are interested in making profits. If it turns out that the world actually is sexist, racist, bigoted, or holds whatever unfair bias against potential founders - that means those founders are less likely to succeed and therefore a riskier investment!
I would never try to judge a work environment by the recruiters (unless the recruiters are unusually bad, which could suggest a toxic management culture). If at all possible, talk to actual engineers.

My two cents on Google and Amazon: Both companies are large enough that making blanket statements about company culture is a dangerous game. What you need to do is find out which silo you would be working in, and try to figure out what the culture is like in that silo.

One thing you can grill the recruiters about is what the employee review process looks like. Both Google and Amazon use stack ranking, which is about the most brutal system there is. At Google, feedback from fellow engineers factors heavily into your performance reviews. Amazon seems to be more focused on measurable performance goals and demonstrable contributions to the company's bottom line.
