Because the hardware is beautiful and the build quality is (was?) excellent. Recent fumbles like the butterfly keyboard design have definitely reduced that perception, though.

I have a Dell XPS 13 now, and while I like it, it's just not as pretty as a MBP. I recognize that that's a highly subjective judgment, but that's a thing that matters to me. The XPS's build quality is good, but not amazing; for example, I've had it for less than a year, and one of the rubber strips on the bottom of the laptop has been peeling off for the last few months.

Overall it just makes me sad that "hostile platform" is even a thing. At this point I've decided that the alternatives are good enough for me, and the better hardware support tips the scales in favor of them.

No, extra mass is needed to make them operational, not politically acceptable.

First is engine mass. (All numbers from memory)

A SpaceX Raptor weighs around 4,000 lbs, and generates over 400,000 lbs of thrust (100x). NERVA weighed around 40,000 lbs and only generated 50,000 lbs of thrust (1.2x).

A fully fueled orbital Starship in would weigh around 2.5M with about 25,000 lbs of engine, 150,000 lbs of ship and 2.3M lbs of fuel generating 1.2M lbs of thrust out of three vacuum Raptors.

For a similar level of thrust from NERVA would add nearly 1M lbs of dry mass. Newer designs can cut that engine mass, but at most in half. And your nuclear ship could get by with less thrust and just burn the engine longer. But that brings two new questions

Where does all the heat go?
NTR send almost all of the heat out the back, but not all. Running that engine for hours on end in the vacuum of space (Instead of the very conductive earth NERVA was tested on) is going to heat stress your engine and everything it’s connected to. Do you need to add massive radiators and insulation to run the engines longer?

How do you take off on Mars?
If you have a lot less thrust, you will only be able to lift a lot less fuel and cargo. And you can’t land or take off on Earth. Unlike Starship NTRs may only be usable in between planets, requiring carrying heavy and expensive landers.

Then there is propellant. A 900 ISP is only achievable with hydrogen (H2), using Methane or water or any other feasible propellant drops ISP below 600, making overall system performance far worse than burning methane in Starship Raptors.

OK, let’s use Hydrogen then. Well unfortunately Hydrogen is a shitty propellent in every other measure. It doesn’t compress well so yet requires larger, heavier tanks. Also H2 is a tiny slippery molecule, forcing you to freeze it near absolute zero in order to keep it from leaking, which makes those tanks even heavier. And guess what? It still leaks. Will you have enough fuel left to fire a retro burn to match orbits with Mars? Better leave with at least 30% more than you need.

Now, you probably don’t want to be killed by your engine on the way to Mars, so let’s add some radiation shielding between the crew and the NTR engines, or put the on a long spar sticking out behind the ship. Both add even more mass.

A NTR ship will likely require at least 2-3x more dead mass than a chemical rocket ship, so the question becomes, what’s the point? Why jump through political hoops when Starship VP can already fly crew to Mars in only 90 days and deposit over hundred tons of cargo to the surface of Mars, and cheaply?
I actually had in mind total GDP--industrial as in industrialized economy, not manufacturing. In terms of GDP per capita Northern states absolutely dominate. See https://en.wikipedia.org/wiki/List_of_states_and_territories... But even in manufacturing I think they're still ahead. See https://www.epi.org/publication/the-manufacturing-footprint-...

Yes, the growth in Southern states is greater. But growth rates don't say much; apropos HN, an upstart can easily enjoy quadruple digit growth rates while the dominate players only see single digit growth, even when there's no reason to doubt their continued dominance. Nonetheless, for manufacturing the story is definitely changing, because of politics (e.g. Japanese car manufacturers and Airbus being incentivized to open plants in the Deep South), because of automation (easier to relocate plants to rural areas), and because there's less cheap labor in the north (possibly a cause, not only a consequence, of changing migration patterns).

I couldn't quickly find any links that broke down manufacturing by value-add or by technology--I suspect by that measure Northern states tend to still dominate in manufacturing, the same way the U.S. still does well in upmarket manufacturing viz-a-viz cheaper nations. But that's more of an educated guess; I don't remember ever seeing any data directly on point.

> Your 3 months is 5 years for someone trying to learn on their own in their spare time.

I learned the key parts of Haskell in 3 months of my spare time from university (where I had much less spare time than I have now in industry). And that was at a time where learning Haskell was much harder than it is now; today there are a lot of really detailed books, tutorials, and videos available, tooling works out of the box with few surprises, and error messsages are way better.

Of course learning in your spare time does not give you as much practical experience and feedback as you get on a job, but it gets you enough to get into such a job.

> You don't have to try and pick apart the online knowledge.

Not any more.

* Step 1, buy a beginner book and work through it.

* Step 2, work through FP Complete's [1] Applied Haskell Syllabus (https://www.fpcomplete.com/haskell/syllabus/). This will make you comfortable with most day-to-day data structures, techniques, testing, benchmarking and so on.

* Step 3, practice building some small applications that you think companies will actually need. Web servers, input validation, streaming data processing, and so on. It doesn't have to be fancy or use "cool" techniques, it just has to be /useful/.

* Optional Step 4, for extra hireability: Become better-than-average in a specific topic. This could be testing, performance, developer tooling, documentation, web stuff, anything that gets your juices flowing. Do a bit of open-source work in that area. Go to some meetups or conferences to see who's hiring, what they are doing, and what might be useful for them

> I want to understand Lens?

Again, you don't need to do that to get a job. I've conducted ~ 40 technical interviews for filling Haskell positions for various companies, and none required this. What is required is that you can do normal /useful/ things, with the high amount of correctness, clarity, refactorability, and reliability that Haskell provides.

Haskell, like mathematics, knitting, and C++, offers near infinite avenues of special topics that you can deep-dive into if you want. People talk about those at meetups because they excite them. But you don't have to do that to build useful software or get a job.

Great write up. Thanks for posting this.

There’s rumor that due to a large number of people taking ML courses, there will be far more people with ML skills than ML jobs.

I hope this is true. There are so many areas where ML skills could be useful. The sad part would be that some industries would be changed forever. The animation industry for example might not even exist the way it is today.
We're always happy to delete or redact identifying information. We don't want anyone to get in trouble from anything they posted to HN. We don't do it by allowing wholesale deletion of account histories, because that would gut the threads the account had participated in, which would be unfair to any commenters who replied, as well as to readers and to the community.

That doesn't mean we don't care about individual users' needs for protection—we care a lot about it, and help people with these requests every day. We just have to do so with sharper tools, and we have a big bag of tricks for taking care of these things. They include renaming accounts, retroactively assigning comments to throwaway accounts, deleting specific posts (especially if they don't have replies), redacting specific info from posts, and more.

> for most web development this just won’t matter

My comment wasn't about most web development, it was specific to using Docker images between platforms.

I getting paid to do this, I don't want to screw with guessing games about whether a particular bug is platform specific or not. I already do this to a much smaller extent with Mac vs Linux development.

There are a fair number of web development jobs I would be willing to risk jumping architectures on, for example right now we do react development which leans almost entirely on node.js and I'm cautiously optimistic that'll be a fairly transparent hop since it runs entirely on JS.
Aside from the accessibility concerns -- which is honestly inexcusable -- the non-centered repo layout is so strange to me:

All that info that's now in the sidebar is temporary. All of it. I never need to look at a project language more than once.

However, it takes up 100% of the height of the page, so when I'm halfway through a README, the README gets offset by some magical space. The ghost of the 1 paragraph of "language/tags/etc." takes up that space. The README is not centered.

From a design perspective, this layout implies an equal level of hierarchy between the right sidebar and the main content. It implies that they should be referenced side-by-side. But that is just not the case. I want to meet the person who thinks that the document literally entitled "README" (or oh, I don't know, all of the files) is somehow as-or-less important than the tags on a repository -- which are usually just the title copy pasted anyways.

I develop open-source things and I absolutely love to use GitHub. In particular, I've spent a LOT of time reading README's and also writing them. I really think their centered layout should come back.

As a suggestion: Maybe they could shift just the _files list_ over for that sidebar, and have any block content not centered?

Or maybe if there somehow existed a compact way to organize that information. Maybe a horizontal layout because there is only a little bit of text. Something like that.

Rolling lockdowns are part of control. No one's expecting miracles until a vaccine is available. Still, Europe is clearly winning this battle. Italy and Belgium had BY FAR the worst outbreaks in the world in March. Now they have a lower new case rate than any state in the US. Any of them, including Hawaii. They are sitting at about 10% of the new case rate of Oregon. Arizona has them beat by more than two orders of magnitude.

And again, a month and a half ago we were on the same trajectory. And we gave it all up, because MAGA, I guess.
When is "tooling" worth buying? Perhaps it's a reflection of the kind of person that I am, but I would always rather build my pipeline internally rather than outsource it. That pipeline will probably become part of the critical path.

Honestly, it just felt like a ton of tech circle-jerking to me. The gyroscope system on the Segway was really cool, but it was like once it got some good words from some tech luminaries like Steve Jobs, all these other people were like trying to one-up each other saying how revolutionary it was. When it finally came out it was pretty much universally ridiculed by every average joe (not so much ridiculed for what it was, which was a neat scooter, but ridiculed for its unwarranted hype).

Agree. You have leverage, not just due to sunk costs but because people in the organization staked their reputations on the acquisition being successful. So you may be able to write your own job description.

That's different. It's one thing to hype something up, but then the capabilities just aren't as futuristic as advertised (I think most people agree fully autonomous cars would be revolutionary), but with the Segway it was completely hyped, then when it was released everyone went "THAT'S your 'world changing' invention??"
ISP of Methane in an NTR is less than 600. And the engine, shielding, and cooling mass increases the ship mass at least 2x to 3x over chemical.
Could HN consider allowing users to delete their own old posts?

We live in a very different world than the one that existed when HN first launched. Self-censorship and careful pruning of old posts is now a necessity for participating in public online discussions. Society is growing less tolerant of diverse opinions every year and comments that are within the Overton window today could get you fired from your job a few years from now.

I don't think we can even predict what opinions will inspire a Twitter mob in 2022. But inevitably one will come here and try to get someone fired for something, which will have a chilling effect on HN unless we can prune our own posts/comments as future situations require.
Tangential comment: I just opened the link with the new design on my phone and it was a delight to look at compared to whatever I saw last time. I think the design changes were made keeping in mind smaller screens, which might be what the user data suggested (how am I to know). But I agree with other comments that the top bar content could be aligned with the rest of the content. Stretching it to each end is causing pain.
Feedback: the screen shots showing how it works advance much too quickly. It's impossible to spot the helper text, look at the screen, and get any context before it flips. Image carrousels with important information are a poor UX.

This is pretty wrong.

> Some hacker-wannabe that sets up a honey pot is going to be thwarted by HTTPS. But if we don't connect to shady hot spots HTTPS doesn't seem to provide that much protection.

Pinned HTTPS certificates provide a good degree of resistance to MITM attacks, and without installing local certificates on the device under attack HTTPS itself stops MITM attacks.

> It runs into the problem of anyone that can MITM via your ISP or home router probably has the resources to also find an exploit around HTTPS.

This is absolutely not the case. Home/work routers are often monitored by suspicious spouses, annoying housemates or intrusive companies. It's very rare that one of these has the resources to develop their own exploits against HTTPS.
