Having a higher route coverage is a function of size absolutely. However, it is definitely not a significant competitive advantage. Economies of scale is applicable in absolute and relative terms.

Airline A can have 100% coverage everywhere in the world and be the largest airline. But if Airline B enters a specific route, there is no advantage to a customer whether they ride with A or B for that specific route. This is why there are so many entrants into the industry.

The biggest factor to the lack of durable profits in the airline industry isn’t labor or unions. It’s the ease of entry into the market which puts tremendous pressure on price. There are no substantial barriers to entry, prices go down until profits are close to zero. So in classical value based investment lingo, it is an industry with no competitive advantages.

The airlines industry in aggregate has never had a ROIC greater than its cost of capital over the long term (>1 yr) for the lifetime of the industry.
The problem is that it's faster to get some solar panels put up than it is to connect them to a grid. Once a community has an energy surplus, then until there's someplace else to which they could send that energy, cryptocurrency mining offers at least some income in the meantime.
The fundamental problem with electric aviation is the terrible specific energy & energy density of existing battery technology. Just for a very rough order-of-magnitude comparison, the most energy-dense batteries in common use today (lithium polymer cells) hold somewhere around 0.2-1 MJ/kg and 1-3 MJ/L [1]. Jet-A (kerosene) on the other hand holds somewhere around 40 MJ/kg [2]. Some of that might be recovered by using efficient electric motors instead of combustion engines, which are typically pretty inefficient, but even then we're still looking at a >4x decrease in fuel range.

Notably though, these guys have pretty modest goals:

>The 30-passenger planes will be driven by electric motors with battery-derived energy, allowing the planes to have a fully electric range of 200 kilometers (124 miles). The planes will also include a reserve-hybrid engine powered by sustainable aviation fuel, allowing it to have an extended range of up to 400 kilometers with a full flight.

Energy lost to drag goes up with the cube of velocity, so flying slow, light planes over short hops might be doable with fully electric engines and modern batteries.

As a side note, it's especially telling that they'll fly with a reserve engine that uses hydrocarbon fuel. This might be done for safety, but I would suspect it's more about making them economically viable while allowing them to be painted as a green alternative. Most routes will likely require at least some fuel consumption.

The proposed changes were "cuts". The reviewer said "remove these lines, we don't need them" not "can you clarify". So more like:

So where do they gain that passion if not from developing off hours?

If you look at the leveling or hiring guidelines for any major tech company, what separates “senior developers” and up from mid level developers are system design, “handling ambiguity”, leadership, “scope”, “impact” and in the case of Google did you write a messaging app.

Even the largest tech companies realize “coding ability” only gets you so far and most developers who want to get ahead would be far better off focusing on the other aspects of software engineering.
I don’t think he meant the computers as a whole were unsuccessful, but the bid to enter the business sector was. The common consensus is they failed because Atari was so strongly associated with games. I assume there are possibly greater reasons, but it is true Tramiel and others tried the pivot and it failed.
Most arrests are for state charges, not federal. Presidential pardons only cover federal charges.

> While I'm not totally behind "nationalize all the things", do you really think the government is less accountable than Meta? (or Alphabet etc?)

Yes. Absolutely, and without any qualification whatsoever and in every jurisdiction at every level.

Government enjoys sovereign immunity, qualified immunity, direct statutory immunity (laws that prevent suing the government) and operates the forum where they are held to account (be it a regulator or a court). It is very difficult to sue the government, and even more difficult to mount a campaign to change a law in a non-corrupt country. This applies to a tiny sanitation district,

Private companies are easily sued, regulated, and if their behavior is bad enough, reputation damage alone suffices to hold them to account.
It does not work if none of the chunks produces value for the customer, yet is necessary from engineering or bureaucratic point of view.

And sometimes you do hit a brick wall or bite something you cannot chew yet must digest.
A more robust grid is the solution. But, in the meantime, you can do what I did and put all of my network gear on a battery so it continues to function for about an hour after a power failure. That gives me enough time to wrap up most meetings and start up the generator or head to a cafe, etc if I need more than that.

Bonus, I use Power over Ethernet access points and security cameras in my house, so even my cameras and the wifi access point at the other side of my house still functions perfectly during a power failure. I plan to add an additional battery which should help the system work for up to 4 hours without grid power.
I’m also self taught and two things that helped me are, ok well 3

1. Read clean code
2. Read clean architecture

Or at least find someone summary of the books. They helped me feel more confident in the code I wrote, the way I wrote it, and helped me justify why I wanted to write it the way I did

3. Look up DDD - domain driven design. I think that starting to learn about different architectural methodologies will help to understand bigger projects better. It’ll also help you to see where the projects went wrong, and sometimes that’s reassuring too because it shows even senior and principal devs don’t always really know exactly what they’re doing

This is a good GitHub repo for DDD. Definitely look into others as well, not saying DDD is the answer to all problems or the best for any, but I just like it lol :shrug:

Oh no, managers in technical teams are usually doing their jobs not because it's fun and exciting but there's no other people who is willing to do those "grunt works" around people. Real leadership happens in the team, not code; code is just a (rather inaccurate) reflection of organization and business. It's correct that it's important to keep it close to the reality, but that's done by people and teams.

The HN reader will (statistically) have the objectively most inane future-optimism out of all of them, latching onto Elon Musk tweets about colonizing Mars, democratizing technology by way of the latest “decentralized” trend, thinking that nuclear power + EV will solve climate change, just to name a few.

They will also have at least double the expected income of whatever group they decide to harangue for not apprecating their “quality of life”.

That article (from the URL) appears to be about Bitcoin, not "crypto"

And the distribution of Bitcoin might be skewed because one of the largest holders (Satoshi) is possibly dead, and many others would be custodial addresses (centralized exchange addresses, and large funds like microstrategy).

Furthermore, many of the addresses being considered would be inactive addresses by people who have moved on to new addresses. In that case, you have many addreses with "dust" balances which are not claimed by anyone, perhaps as much of 80% of addresses which have ever been used. I have gone through at least 6 such addresses myself, and I no longer use the Bitcoin network (or have funds on it)

It's a lot different than the dataset used for considering wealth distribution among a known population number, whose monetary declarations are necessarily exposed to a government which can publicize this kind of data in a more accurate way.

right now i am thinking i would simply do 1:1 streaming. so no transcoding. what you put out is what the audience gets. so if you stream with too high if a bitrate, tough luck. i could handle it with couple of cheap VPSs.

>Parents in these 34 most-affluent LAUSD elementaries donate an average of $876 per student, our analysis shows.

That's like 1/5 of the gap between APS and the next highest school district. It looks like the wealthiest in LA are able to make up for the difference. But I am suspect of this article. The parental contribution is only 0.4% of the LAUSD budget but somehow it's making up a 20% funding gap between low and high income schools. Very suspicious that they're cherry picking but I don't have the time to dig in.

>Pick one of the "High Income / Low Expenditure" counties - Forsyth - as an example. It has an average household income of $112,834. In that county, there is an entire parallel non-profit organization that raises private donations to fund programs in the school district. Here is an article describing their work:

Google says APS spends 17k per pupil while Forsyth spends 10k. For 20 schools with 200 kids they'd need 28 million in contributions to equalize. Raising $115k by selling ducks is a drop in the bucket in comparison.

Also, APS does their own fund raising. Brief googling reveals that they've raised 7.4 million through this one site alone:

What else would you use the battery for?

Efficiency.

You can store excess energy from local microgeneration, particularly solar, that can be used later. With our current pricing model in the UK, that is several times cheaper than selling the excess power to the grid for a token return and then paying full price to have the same amount back from your mains supply later.

Some systems can even be configured to charge their battery from the mains at quiet times (when, again in a typical UK pricing model, the cost-per-unit can be much lower) if there isn’t enough local generation to fully charge it, for example in the middle of winter.
Thanks. I had read of success infecting tumors with virus, that the immune system will control only outside the tumor. But I didn't hear any more about it. What happened with that?
Minimal affect. Most marijuana possession charges are state, not federal, and presidential pardons don't affect state charges.

In South Africa we've been having load shedding for a record amount of time this year. Worst it's been so far is 2 2hr slots and one 4hr slot every 24 hours (so 8 off per day)

It's not winter though, and we tend not to heat our homes like Europe.

No, it's the "internet is the platform for sharing" argument. Copying, sharing work of others is not, in essence, stealing that work. It is sharing that work, maybe illegaly, but then it is illegal sharing, not stealing.
You'd be surprised at how many Americans don't understand how Presidential pardons work either.
Yes they do. But we -- that is, our nominally democratic government, a "power structure" which you have arbitrarily equated with a collection of private corporations -- have placed restrictions on immigration, and some light restrictions on foreign ownership of real estate itself, for precisely this reason.

Secondly, Canada, whose real estate markets have been even more seriously disrupted by authoritarian regimes across the Pacific Ocean, have already placed outright, albeit temporary, bans on citizens of those regimes from parking their capital in the domestic real estate market.

Your characterization of my argument is specious and straw-man-esque. You are assuming that globalization is a given, that borders are always porous, that neoliberalism is the only way of looking at the world. I am kindly inviting you to reconsider your point of view, in light of evidence that it has made housing more unaffordable for the many Americans, disrupted their livelihoods, and dissolved their communities.

Or you can keep making colorless jokes to yourself about the property markets on Mars, up to you.
Same - I can see the beginning and a partial end, but I find most of my ideas and inspiration occur once I get into it, and i can never see the final process to get there - it happens as I go.
I used to live half a mile from a power plant in another state and I had far more outages there than I've had in California. That said, there are constant incentives to reduce peak energy usage, and there were a couple weeks this year where they almost did rolling blackouts. So, they still struggle with meeting demand sometimes.
Well, Denmark is tiny so if its not windy in one location then its unlikely to be very windy in an other. Same for the sun.

EU has however already taken it up as a project. It is called the European energy grid, which as I describe above forces countries to sell to each other. There is an economical limit to this from transit and transport costs, but in concept the whole union is already a single grid connected from the southern part of Italy to the polar circle in northern Sweden and Finland.

Denmark consumes around 33 Terawatt of electricity. They import 20 Terawatt. They also sell about 14 Terawatt of renewable energy. Sweden (hydro + nuclear), Norway (hydro), and Germany (coal, gas) are the main players that provide those 20 terawatt of electricity to Denmark.

This far up north the sun doesn't cancel out the still periods of wind. Demand for heating during winter far exceeds the few hours of sun that you get.

Green hydrogen, as nice as it is for reducing the emissions from steel industries, still costs about 10x of nuclear if you use that green hydrogen to produce power. There is a big economical reason why no one is doing that at this point in time. Estimates from researchers in the field varies from around 2035 to 2055 before we will have our first commercial green hydrogen power plant in operation. Still green hydrogen would be a nice way to recover costs if Denmark did decide to go for 300% overcapacity, but they would still need to heavily depend on Sweden, Norway and Germany to provide the electricity when demand exceeds supply. Their own grid will not suffice.

That's why I think Bitcoin is outdated (yes, get your pitchforks), and you really need something that can do smart contracts.

Bitcoin you can hold it, transfer it, and not much more. Having smart contracts (like Ethereum) allows you to have something like Uniswap, which is decentralized and allows you to trade your coins.

Yes, it's not a fiat on/offramp, but if stablecoins are actually good and backed, in the scenarios you describe you would just buy/sell stablecoins and at a later point exchange those stables for cash.

Who's to say that the projects are incomplete if you have achieved what you wanted from them? Sounds very much complete to me, even though the final result might not be useful to anyone else.
Early space exploration is very tightly coupled with politics. Given the USA capabilities, it can be argued that the first satellite being Soviet was a result of political bureaucracy of USA. They explicitly denied von Braun's request to fly Jupiter rocket - which were in relatively good shape - to reach an orbit. On the other hand, subsequent first man in space and first man on the Moon both shown strengths of respective countries' technology. Even after 1975 Apollo-Soyuz flight healthy competition remained - it is colorfully demonstrated in the series "For All Mankind", which just had its 3rd season.

Now, 65 years later, we're getting into commercial space space. Politics get a bit less important, but there's still a long way to go.
Forget satellites: launch water, rocket fuel, 3D printing material!

Relativity Space is building 3D printers large enough to construct orbital-class rockets in one piece. Others will follow. If they can make printers work in vacuum at 0g, that's how we build our next-next generation of space stations. SpinLaunch wants to launch around the clock, multiple times per day. Just keep flinging materials and consumables to the construction robots building our future habs.

"WSN also accessed student evaluation records for courses taught by Jones, which showed that his scores had been consistently low for years — long before the spring 2022 student petition. In the past five years, Jones’ co-professors teaching the same course typically had scores around or above 4.0 on a 5.0 scale, while Jones averaged around 3.3. In his final semester, his evaluation score dropped to 2.4. The stark contrast between those numbers shows that students weren’t just complaining about the intensity of the course."

No. The translator corrected themselves. Zelensky said he wants the West to say what would happen if Russia conducts a nuclear strike before, not after it happens. This is an artifact of differences in sentence structure between English and Slavic languages. Wait for a translation that's not done on live TV, that's going to be much clearer.
What gets me is how Jack Welch was held up as an amazing businessman and model for corporate flexibility for years while his changes utterly destroyed GE's future for short-term gains. I'd argue the same thing about the Clinton administration and Greenspan specifically.

It takes many months to develop new housing in the U.S. Even when you have local political support, there's a lot of custom manual work and so forth.

It's also very hard to find examples of long-term successful large-scale (town-scale) growth. So we can't just move substantial fractions of people from our largest cities to mid or small-sized cities in a matter of months or years (and get satisfactory results).

Undoubtedly NIMBY forces around the U.S. are partly to blame, but the Covid/WFH exodus is surely the more important factor at this point in time.

I was curious about this, because I also think of the staff engineer as a newish thing, and I don't believe I've ever actually met one.

I searched my old email for the term and found that the first reference I have was in January 1996, in a HotWired HotFlash newsletter:

"Java - so-named because it evokes liveliness and speed - is the brainchild of Arthur van Hoff, a senior staff engineer at Sun Microsystems. He's the HotJava engineering lead, has designed most of the Java applet API, is the implementor of the current Java compiler, and is the author of the book "Hooked on Java." Get the scoop behind the hype, when Arthur van Hoff joins us in Club Wired on Friday, 12 January, at 12 p.m. PST (20:00 GMT)."

After that there's really nothing until the term starts appearing in LinkedIn notifications around 2010. I guess that just means it wasn't used in the circles I moved in, so only became visible to me when I joined LinkedIn.
