Handshake is a blockchain which wants to replace existing DNS registration system. So when you want to look up example.com, instead of consulting IANA's database for "who owns .com", you consult the Handshake's blockchain.

The zooko system uses a "hack": since, this is blockchain, there is entire past history on the chain. So you can keep repeatedly updating a random field (like a TXT entry for some domain) and use equivalent of "git log" to read the entire timeline.

This will need a special client, which will parse blockchain for such updates, but everything on blockchain needs a special client, so not a big deal.

Re "5 million users" -- this is a very good point, and yes, if this takes off this will be significant problem for Handshake blockchain. I suspect this is the core of disagreement between Zooko's author and designers of the Handshake blockchain ([0]).

From the point of Handshake authors, Zooko system uses blockchain resources, but does not help with main mission (make Handshake team super rich by taking over existing DNS system).

From the point of "publiush", there is this Handshake blockchain which has authentication solved, and it can be used for all sorts of fun stuff. The fact that this was not original intent just makes it more fun and exciting.

Thank you for your work! I use it and I can vouch for the fact that it's great.
I'm sorry we gave you that impression.

After several years, there's been nothing more humbling than trying to get Simula off the ground (first developing the software, and now the hardware). We've been smacked in the face so many times. So we don't feel very arrogant, at least.

Maybe our tone isn't quite right. We're just trying to convey to people that our headset has a different use case/is designed for something different than portable gaming/entertainment.
Interesting how she assumed none of the men would be raped. Newer CDC stats (since ~2010 when they started asking men if they've ever been "made to penetrate" by a woman) show that female-on-male rape happens a lot more often than people think.

Something I've found useful when perpetrating custom languages is to, as early as possible, bring up a REPL that handles multiline expressions sensibly.

This (a) requires me to build stream/incremental parsing (b) gives me a tangible feature out of doing so that makes my life better (c) means from then on even if the production uses of the language are all batch shaped to begin with I'm regularly dogfooding the non-batch code paths.

(because yeah, it -so- does hurt trying to retrofit that later on, so 'finding a way to trick myself into -wanting- to build it in early' was rather a win for me ;)
I'm seeing things like this. I should have more specific. I have metabolic syndrome. With variants like Omicron that have higher ability to bypass vaccines, I'm not taking the risk. Covid of some sort will be with us, but hopefully it won't be at this level of risk for people like me always.

It's not mobility if you're being forced to work in a way that doesn't suit you. If everyone is remote, then the x% of developers that don't want to be remote are left without an alternative.

It never stops. :( A person's tiny subset of experience is rarely indicative of anything but that, a subset. I conduct every transaction I can via credit card for two reasons: cash back and protection via the ability to revert fraudulent transactions. But I also have known rational, "techy" (SWE) people who refuse to use them. And I know way better than to attempt to project my experience on "everybody".

You can say that about most current cars in the US, especially with the proliferation of giant SUVs. But that doesn't make it true about the concept of a personal car in general.

Think something like the Smart ForTwo, Fiat500, Mazda Miata, or Japan's Kei cars. If you want something slightly larger, see things like the Honda Fit, etc. Other countries have various cars of similar size and flavor as well. Such cars would serve a big majority of the US driving populate just fine.
Easy explanation, who wants to pay for a masked/zoom college experience? Add jab requirements every couple months, “covid” surveillance and contact tracing, and intentionally minimized social activities/opportunities and why would anyone pay 50k/yr for that?
edit: deleted, not worth trying to add any discussion to a topic like this.
20 years ago was 2002... yes in 2002 people who had 3-4 kid drove an SUV, a van or a mini-van, just like they do today. The argument isn't about average vehicle size, the argument OP made was to eliminate ALL large vehicles.
In my city, churches actually made a choice that's even worse than that: on the weekends, it seems that there's some kind of deal with the police, and churchgoers just park right in the bike lanes all down my street. It makes my street, which contains two bike lanes, absolute hell to bike down on weekends.
One of the main issues with EV fires isn't necessarily prevalence, but rather the hot, explosive fire caused by battery packs, which cannot be easily extinguished by firefighters. Extremely large amounts of water are required, and even with this, fires may burn for an extended period of time.

Furthermore, lithium ion batteries can reignite after many hours, when the car may be stored close to other cars or indoors.
Eh, unless it is a niche grocery store, every actually independent grocery store I have visited has had limited selection and mouldy fruit.

I don't think anyone disputes that running a small business is hard. It is just that most don't do a terribly good job of it.
Children of affluent parents are still going to college at very high rates. The people suffering most from the expense of college are those who would benefit most from a college degree. Whatever the causes, people with college degree earn much more over their lifetimes than people without degrees. The trend in lower college enrollment seems like it will only exacerbate wealth disparities.
Being able to use formatting patterns similar to python sounds really awesome. It makes formatting with long formatting strings really a lot more expressive and more readable.
Generally this process would be called linearization.

You can create a complex, nonlinear, numerical model of the full system in as much detail as you want (eg implemented in a block sim like Simulink, or MBD software like ADAMS, or just A and B matrices derived manually but incorporating nonlinearities like sin, etc).

From that you can evaluate a whole bunch of finite differences around an arbitrary state (linearization point), which are the components of the A and B matrices. This is an approximate, linear model which is "close enough" in behaviour to your real model for states that are "close" to your linearization point.

In practice if you're moving far away from your linearization point (eg a 6 DOF robot arm with large displacement of all joints), you'll need to re-compute the linearization each timestep, around the current state, and re-compute the LQR or MPC solution from this "new" approximate model.

Here's some linearization code I wrote for a library that's used to teach controls and robotics in undergrad. It takes as a input a "model" that's an arbitrary function that generates the next state from a given state, and computes the jacobian matrices by finite differences: https://github.com/SherbyRobotics/pyro/blob/43dcb112427978ff...
What's the problem with building, aaaaah, a COMPILER?

This may be true, but at the same time, if the goal is to make a lot of money, rich parents and other luck aside, a college degree in a high-paying major is probably the best shot at it, instead for example trying to copy Garry Vanverchuck or Steve Jobs. Drive and effort apply for all professions, but it's just that college grads will get a higher return for their effort.

They're turning that energy from the sun into electricity instead of local heating.

Of course solar panels are only 20% efficient or so and thus will still heat up, but not as much as if the panels were not generating energy. Damn thermodynamics, you can't even break even.
"Ghost in a Shell" is 100% CGI / Anime, but the fights absolutely had consequences and weight.

I actually hate Attack on Titan as a show, but damn the action scenes actually have weight and logic to them, far superior to the Marvel stuff despite being 100% cartoon.

---------

That being said: Marvel seems to be going with more of a "Dragonball Z" or "RWBY" approach to combat. Which is fine as long as the writing is good enough. Its a different style for sure...

Except ya know. Dragonball Z / RWBY largely does it better.

-------

Its less about action shots and more about demonstrating superpowers. Everyone knows Goku will try to end the fight with a Kamehameha wave. At some point, Goku will go Super Saiyan or beyond, etc. etc.

Similarly: Capt. America will throw his shield, Iron Man shoots some lasers, Hulk will grab, punch, and grapple something.
1. That number seems way off. What are your assumptions?

2. I haven't looked at the data, but I'm going to go out on a VERY short branch here and assert that the entire delta between US and CA tax rates is not consumed by higher education.
Im very skeptical of this post:

1. Many trades also pay like crap and have a very limited window in which you can do it. In addition many are not welcoming to women at all, regardless even if you take the highest paying trades, do they pay more than the highest paying careers that require higher education?

2. Which boot camp? How many people ended up like your daughter? How much was it? Without these facts no comparison can be made.

3. Some colleges perhaps, smart people can get full scholarships and even without that community college plus a cheap state school isn’t expensive. Link to your study? Did these people not go to college?

4. As you’ve already demonstrated college is hardly required let alone loans.

I’m surprised this is the top post.

This also has a tendency to create ever-building organizational pressure for the Big Rewrite. And when the pressure overcomes the resistance, the dam bursts and all the debris turns into a never-finished ball of mud because there are so many business hopes and dreams pinned on the new system. Identifying release valves along the way can prevent that quagmire.
Don't forget the paramount of the Mountain of Shit:

- a billing system

There's a reason why there are b2b companies that specialize in billing. When people branch out it's often billing and X, not X and billing. And even then sometimes they pull back. ADP bought a bunch of companies outside their wheelhouse and then spun them back out.
The "fabled" small biz move to Facebook happened 4-5 years ago and has since shift back. During that time, I'd hear warnings (much to my enjoyment) that my job would be in jeopardy. Things are shifting back now, hard. I've had clients stop posting to social media, and instead are reinvesting in their website, which they control 100%. The social media shine has warn off for small biz - it's just another marketing channel and one you don't control.

Microsoft chose to extend git for their internal source control, and Facebook went all-in on Mercurial+extensions. Google also has a Mercurial+extensions interface to their monorepo. The sheer size of their monorepos mean that tools that don't work for them will work elsewhere.

In particular, Git has made improvements recently working with giant (as opposed to merely bit or still-too-humongous-to-manage) repos so it's now workable after massaging the config.

The other alternative to Perforce is SVN. There have been some improvements with it that make it more workable in today's git/"decentralized" world. Not knowing your particular use case it's hard to say if that's at all appropriate.
We don't promote the weight because we aren't yet at the stage of integration where we can promote it at. However, you can expect it to be around 800g front+back combined, so around the same as an Index.

In response to that I will take quote "Only Dead on the Inside" by Author James Breakwell

"A minivan has room for luggage. It has room for air. And it has room liquids. That's right: It has space for THREE states of matter. Kids shoot liquid out of every orifice, and it constantly needs to be replenished. The minivan knows that it knows everything. Each minivan has at least twelve state-of-the-art liquid stabilization chambers, known to commoners as cup holders. That's way more than any other vehicle. It's basically a cup holder collection with an engine attached. If you want to you can haul a dozen slushies at once. Can't find slushies at the end of the world, not my problem. I don't have problems. I drive a minivan."

More seriously, when we go to visit family you can't fit luggage for a family of 5 and that family in a Camry, also when you have to grocery shop with 3 small children you have to be able to fit both the groceries and the children in the car at the end.
To paraphrase John Ousterhout: If a system has a few parts that are very shitty, but those parts almost never need to be touched, then they don't have much impact on the overall shittiness of the system.
This would be the crux of my disagreement with the phrasing of the article, even though I agree with many of the details, in specific contexts.

For me, shitty code implies poorly-named variables, confusing logic, brittle tests that couple tightly to the implementation and resist refactoring the code under test, etc. Shitty code makes it harder to understand what is going on, and makes it harder to adapt to new requirements.

At the other end of the spectrum is what I call "gold-plated" code. This is over-engineered, or just overly aesthetically pleasing for a practical and utilitarian tool that will eventually be replaced. It's code that was written to satisfy the perfectionist impulses of the author (we all have these), rather than to add business value.

In the middle is pragmatic, utilitarian code. The level of quality required to be in the sweet spot of course depends on the audience and longevity of the code in question. A language stdlib should be much higher quality in many dimensions than a startup's prototype. So shitty library code might look nicer than gold-plated startup code. It's all relative to your use-case.

In other words, as with about 50% of such thought-pieces that get posted here, I can summarize my objection as "don't give unidirectional advice when you're optimizing a U-shaped error function". You can err by making your code too polished and not polished enough. For a given startup, it might be that the most common error is to gold-plate, and so the advice "make it shittier" is right most of the time. But you're missing the underlying principle if you think that's the right advice all the time.
>As long as California does, and most other places allow them, we're going to continue to see surprisingly high levels of startup formation and company success in California, despite all the bad things being true.

If that were truly the case wouldn't a number of other states also be banning non-completes in hopes of attracting businesses? Some quick googling shows only the District of Columbia, North Dakota, and Oklahoma have similar bans on non-competes as California.

> I’d much rather we over-design stuff to last decades, at least at the chip level where overedesigning is super cheap.

Engineers are working on it.

From a follow on article by the same author.

"An emerging alternative is to build aging sensors into the chip. “There are sensors, which usually contain a timing loop, and they will warn you when it takes longer for the electrons to go around a loop,” says Arteris IP’s Shuler. “There is also a concept called canary cells, where these are meant to die prematurely compared to a standard transistor. This can tell you that aging is impacting the chip. What you are trying to do is to get predictive information that the chip is going to die. In some cases, they are taking the information from those sensors, getting that off chip, throwing it into big database and running AI algorithms to try to do predictive work.”

One big issue with making a no-college a viable option is that in the US the school education is absolutely atrocious. In many colleges the first year of science or engineering degree classes focus on providing a decent background that should have been taught at schools.

This needs to be fixed for the school-only path to be viable.
I'm currently writing a compiler so I'm not new to this, but I've no idea what you just said. Have you any links to explain it? TIA
Right now, here on the bleeding edge of VRPC, it would be something like $999. I'm seeing it as a Chromebook when they first came out — interesting concept, but not yet proven in an actual working environment.

Alternatively, some sort of money-back guarantee would be nice. "Try working in VR for 30 days, see how you like it."
It didn't appear to be working after a couple of attempts. Opening the console shows a lot of HTTP 500 responses coming from /api/v1/hn/poll/status
Look at the bright side. At least Hell is always warm, and plenty of interesting people to talk to.
Read it this way;

There was also a pattern of considerable within-group variability.
4.5 sounds similar to just having a high minimum billing period. Over on Reddit, I heard of people using one day as the smallest billing period. To avoid all the small requests.

Meanwhile in most of Europe, college is free. I wonder how their attendance rates have fared in comparison.
If you just count Manhattan at ~70,000 / sq mi it's certainly up there in terms of population density. The outer boroughs (and Staten Island specifically) pull down the average quite a bit.
> 10x more windows/virtual screens than PCs & Laptops

That's a productivity drain not a benefit. Modern operating systems could already drown us in zillions of screens if it were actually useful - it's not. That's a productivity fantasy element, like people pretending it's possible to multi-task (more screens, more work, more output). All you get is the equivalent of the hoarder clutter of a thousand browser tabs for no great reason. Humans max out on productivity and usefulness gains from additional screens at a very low number.

> Persistent ("always on") computing wherever you are able to walk and think.

A tablet, a smartphone - it's a trivial difference in timing, as those items are a moment away from use in terms of always on. And where are you walking with a VR computer on your head?

> Promotes better posture (you don't have to sit hunched over a laptop screen, but have more freedom of movement).

That one is false and probably your worst premise. Posture is a choice, you either consciously choose to pursue better posture and constantly reinforce it or you don't, and if you don't then absolutely nothing will keep you from bad posture. A VR computer on your head is very low on the list of things that is likely to finally encourage someone to consciously adjust their body toward better posture. I'd bet on the opposite outcome as far more likely, body damage from wearing a heavy object for too long.
> amateur professional

What exactly do you mean by that?
A little off-topic, but does anyone know if there's been good research about the long term effects of having a screen a few millimeters away, beaming photons to your retina continuously?
I had a very different reading of the article, colored by my own bad experience.

Sometimes you start off with this cool idea/hack to solve a problem that could have been solved some other way. But your cool hack solves the problem and more! Then your fellow team members all want it to be even more powerful, and your cool hack slowly grows into a monstrosity.

In these situations, often your manager did not particularly want you to do this, but he let you do what you want. He does want you to be productive, and this doesn't count for that much. But since the team is now dependent on you, he does expect you to maintain it. You now end up with two jobs: The one your manager hired you for, and maintaining this thing.

I would love to write my own DSL to solve a problem at work, and this post read to me as a cautionary tale on pursuing that goal - unless management is aligned with your vision. If they're not, solve it the boring (and perhaps nonideal) way.
Another one of these things that could have steered us all a different way, if only.
The colleges were willing to jack up the price to take advantage of the government giving out loans. They are a major part of the problem as well.
The bizarre thing with higher education costs that no one's really explained to me is why schools simultaneously spend more and more on administrators (who are full time staff), and push more and more teaching to adjuncts. The claim I've heard justifying the growth of administration staff is that regulatory compliance becomes more onerous over time. But no school is judged on their regulatory compliance. In industry, we often want to make sure that the core value is staff, and stuff that you have to do but won't distinguish you, you may as well contract out. So why aren't administrative compliance obligations contracted out to some overseas firm?

We've gotten to the point where it would actually be cheaper for students to hire their own adjunct to each them 1:1, than to go to some universities.

Updating with numbers:

- USC tuition is >$60k/yr

- Adjunct professors in CA apparently earn $34-$43k/yr
