not an expert in optics, but I thought the limitation of curved sensors in achieving the hypothetical reduction in lens complexity is every focal length would require a different curve radius? So you'd have one focal length that would be significantly simplified because the curve of the sensor would match the curve of the focal "plane" and any other lens you attach would have to become equally or more complex to match its curve to the curve of the sensor? I know for cell phones this wouldn't be an issue, because they have a single fixed lens, but for all the cameras with interchangeable optics, does flat makes more sense?

EDIT: after a bit of thought, if I'm correct above this would also benefit optics in many industrial applications. My brain is usually rooted in cameras people take pictures with, but there are optics and sensors in a lot of other applications. And of course saying "just cell phone cameras" is funny because they are by far the most popular cameras in the world, just that I never use them so they are a bit of blind spot for me.
We're not here to compete for most cynical take.

$100 is not really a price point for any of the things you mentioned, and the way PaaS charge is often restrictive of development model (want microservices? we charge by the service. want a monolith? sorry, we only have instances up to this size. need to scale in smaller increments than "one machine"? too bad.) When I helped build my first platform, it was a migration from Beanstalk to Kubernetes (1.8 at the time).

Not only did it save 70%+ costs, it allowed developers to cut services as large as they wanted, and scale them as fast or slow as they wanted. Metrics and logging were nothing they had to worry about on the infra layer either.

I wouldn't build these things again, OAM / KubeVela is a nice compromise if you want one.

Also, I wouldn't give a dev direct access to Openstack the same way I woudn't give them access to Kubernetes itself. They have too many footguns and too much complexity, either you end up with half-baked deployments or half the teams time spent on doing things the right way.

50 years of failed doomsday, eco-pocalyptic predictions; ‘experts’ are 0-50

The article has the wrong caption I would think ("running K3s on a bunch of PIs" would be more fitting).

Netbooting a bare metal environment is quite straightforward for the PI 3 (dnsmasq has it all) and takes around 15-30 secs.
This article doesn’t make sense - it’s basically says here’s a guy who worked hard, was frugal, and invested for the long term - but he was just lucky (because the past 60 years of asset price returns were amazing) - except how many other people were in his relevant cohort…tens of millions more or less who have had this same opportunity? Not saying the next 60 years will be anywhere near as good, but I think it’s folly to dismiss this “strategy” as most people would be quite happy with an outcome that was 25-75% of that.

From the k3s readme, it states kubernetes is 10 letters stylized as k8s. Half of 10 is 5, and then the project "stylized" it as k3s.

On top of that, because of the way audio was recorded to vinyl, the higher frequency a sound was, there would be a disproportionate amount of wear/friction, I think.

Either way, in this case the article is referring to the ultrasonic tone, and not to the records overall.
Yeah maybe the coronavirus economic recovery committee should have been stacked with business leaders from the medical sector instead of the fossil fuel industry. The future looks bright for those manufacturing and developing covid vaccines.
Most (if not all) our switches in the datacenter are capable to perform as transparent clocks. With transparent clocks you can keep the time sync error down to less than 5ns per hop
And Florida and Texas coincidentally have a much larger share of warm days in which people are more likely to socialise outdoors anyway (where it's proven that transmission is far less likely).

Not sure it matters, but also not sure it doesn't, so my point is that looking at a single factor is very much dishonest.

This describes most working people I know, who mostly with houses and assets would be worth $100k-$1M or so. But they do range across a wide strata of society, from nurses and medical workers to comic book artists to programmers [edit: Those would be my artsy friends. Apart from them, guys in HVAC are buying new houses left and right]; a nurse anaesthetist friend of mine just celebrated her and her husband crossing the line to $1M (including her house equity). Had a little party =D But these are hourly, wage working people, not speculators. If you have $1M you can't live off the interest if you have a house, a car and kids, especially if it's mostly tied up in the house.

Please try out course - https://altcampus.school. It's not ineractive in browser but solves the core of your problem in a different way.

Please try it out, would love to get your feedback.
I would suggest reevaluating your financial approach. It will take time and effort but you can become independent of your job more quickly then you might expect.
Dear god, no. No more messing with URLs.
So I hope you enjoy the tool!!! If you're open for us to connect and learn from your experience, it will be wonderful. My email is mailan@padka.com
There is no reason at all to boot a raspberry pi 4 from an sdcard in 2021. It's the wrong tool for the job and the worst option you can choose.

https://github.com/pftf/RPi4 enables several alternatives, all faster and more reliable

* usb3 -> sata

* usb3 -> nvme

* iscsi

* ipxe

* netboot.xyz via pxe or usb

Not op but afaik all courses from educative are from them, you can submit your own on slip
A copywriting tip:

Replace "With Berowra you can get a CMS up in a minute, not a day" with just "Get a CMS up in a minute, not a day".
I've looked into using educative.io for course creation. There is a little bit more of politics involved when creating the course because of the expectation of high quality code. Also they use internal Docker tools to be able to create the interactive coding environments.

Slip, which I am using right now, is more straightforward and the ability to have code snippets in line which flows with the material is awesome.

Also, Slip is working on integrating with multiple platforms (StackBlitz, Figma, Repl, CodeSandbox) so we can leverage those platforms as well.

Both have a great offering and creating a course is "free" so would recommend giving both a try if you're looking to create a course.
If I watch my non-techie family members use their computers, they hardly use anything that isn't either in the browser or using electron.

I used to see a few things like Acrobat Reader (now killed off by pdf.js), Word (the college seems to now launch the web version by default), Skype (now Electron MS Teams) etc.
I would be highly surprised if this wasn't a case of "they either did it or they just haven't been found out yet" for most regular institutions.
From my own experience, they're probably flashing the RPi4's EEPROM with an updated bootloader and config to enable netboot. Here's the official documentation on it: https://www.raspberrypi.org/documentation/computers/raspberr...
Slightly off topic for the topic of "Staying Employed," but "Don't spend everything that comes in, and save a good chunk of your salary." It doesn't matter how much you make, you can always spend more.

I've watched far too many people over the years get sucked in by the monthly payments on a huge house, luxury car, etc, and while they can pay it, there's no slack in their budget and very little in the way of a buffer. I've also watched a few people go from $hugenums to $reasonablenums for income, and if they've lifestyle inflated their way to consume the $hugenums salary, welp. Doesn't go down well - the BMW dealership doesn't particularly care about your salary problems, they care about your loan/lease payments.

If you can keep your spending down, and build a buffer, you've got plenty more options than just "not missing a paycheck."
That pages needs a lot of work before you try presenting to people who aren't into category theory. I know it's not but to someone who doesn't know the jargon it'll just looks like crankery.

And why Chrome market share keeps increasing.
The situation is ludicrous isn't it. One of the major agri-businesses sucking the life-system out of Australia (i.e. water out of the Murray-Darling river) is a chinese owned business at the top of the river system.

It all depends on your perspective. Some people are more Australian than our politicians, yet they look Chinese. It's a massive melting pot of variations.

My opinion now is that the Crown (not the casino) is extracting all the value it can from Australia and then run it into the ground, and the other powers that be are doing it too.

If Australia ends up against China in conflict, a lot of people will be tearing themselves apart inside.

At the other extreme, a lot of Han Chinese see every other non Han Chinese human as inferior (in varying shades of inferiority). There are a lot of Han Chinese. This is a scary situation. The racism runs in both directions.

Precisely. They are works of literature, not predictions.

One thing that seems to work for me: follow your curiosity. Admittedly, I am still a young programmer (shy of 30), but so far this has not yet failed me. During job interviews I usually show some game I made in my spare time, and even though the game hardly shares the same tech stack, my genuine enthusiasm while talking about it and showing it off makes them excited too and make them want to hire me. On top of that I also have some open-source contributions that I made because some project had a bug or missed a feature I needed. I never did it to increase my brand but it sure doesn't hurt. I also share the books I've read on my personal website which can be a nice conversation starter. I usually get to take my pick from several companies whenever I'm looking for a job.

PHP 8 vs. Java
Interesting, maybe a physicist could clear up for me if they broke the so-called Schwinger limit (so they had an electrical field so big EM started behaving nonlinearly).

I am still confused about what this limit means. Do you need a big enough intensity to get nonlinearity (as the wiki for Scheinger limit seems to indicate)? Or sufficient frequency/energy (as the paper seems to indicate)? And isn't the EM field already nonlinear since we see such things as spontaneous emission and, in general, interaction with all charged particles?

Sorry for throwing my questions at you
Great question! It's similar.

We're a brand new startup. Only a few months old and we're currently a team of just 2 people.

One way we plan to differentiate is by being the easiest tool to use on the author side.

We've seen some early users already spend 10s of hours in their course per week which is really promising.

We're actively thinking of ways to transform awesome developers into great course teachers.

One hack we found was that a lot of great devs don't realize how valuable their knowledge is. We added a presale feature to encourage our most promising authors to build an amazing course.
Some convincing citations would be nice, if you can provide them..
To their oppressors, perhaps. But if they are also assholes to everyone else then they are just assholes and the oppression has nothing to do with it.
Many? No.

Some? Given the laws of probability and the points I raised in my previous post, yes it is possible.

If you take issue with BBC's mission (https://www.bbc.com/aboutthebbc/governance/mission) then I suggest you research the same content from different sources rather than moaning about it on HN because for a great deal of people in the world (and especially in the UK) the BBC is a great source of accessible content. And frankly, it's much easier to criticise someone else's writing than it is to publish something that is both informative and accessible.
Of course we go inspired by the Google Spanner project and what they have published over a decade ago. Hats off to the Google Spanner team
VB6 is definitely old
As a software engineer with 2+ decades in the field, this always is a worry in the back of my mind.

I excel at and enjoy programming. I always have since I first learned on a PcJr. I have been a Team Lead, Software Architect and other roles but I would like to stay employed as an IC as long as I still enjoy it.

Ageism is a thing. I believe this "personal brand" strategy is the way forward.

While it may be possible to pull off a jaded, "I've seen some shit", "get off my lawn" attitude, it will probably make everything more difficult. I try to keep a positive attitude and avoid being the guy nobody wants to work with. This, combined with a mountain of experience, will hopefully keep me gainfully employed so long as I still want to be.
With stuff like this the "right tool" is whatever you have and usb3 -> sata adapters aren't all that common while functioning SD cards are.

Yeah there are crappy ones but if you stick to ~2GB and decent vendors (like most people do) you're unlikely to deal with them.

If you live in a house with poor airflow, consider a whole house fan. Run it in the evening / overnight / morning with the windows open, then shut the windows (and shades if you don't mind the darkness) during the day.

There is an Ask This Old House episode where they install a whole house fan. [0]

Even if this doesn't remove the need for AC, it will decrease the load on the system by increasing how much heat the home's interior has to absorb before the AC kicks on.

We called these "attic" fans when we had one in the 1970s. They were huge, required a massive hole in the ceiling, and were loud. Modern ones are sound / thermally insulated, much smaller, require a smaller hole in the ceiling, etc.

Google has problems money can't solve as a company. I personally won't, and I coach juniors to stay away from many of the big names purely because of their toxic influence in the tech sector. They are of course free to do as they like, but I have an alright success rate with getting people to pass on those jobs to do something somewhat more constructive elsewhere.

It's like Fintech; a black hole of talent away from actually important work that needs to be done. You get that much capital condensed under one company, and it starts to channel itself against overall societal interests as it seeks to ensure it's own survival distributed across jurisdictions, fueled more by ignoramt adherence to past performance predicts future results amongst the capital management class implicitly picking winners through retarded capital overvaluations through overly aggressive M&A's and purging of the competitive landscape.
This is one of the things that's been worrying me for a while. I worry that Australia's experiencing its last bubble. Germany is somewhere I want to settle down, but it's so hard to up and lift your whole life somewhere with so much uncertainty.

To the point of the post, though — I'm not so worried about surveillance in Australia. The bigger worry for me is the lack of our population's interest in real issues. When the level of surveillance does become a real issue, will our population even care?
heh you've got a point - I don't think anything else comes close
That doesn't seem objectively true. It seems like the only working alternative to what we did was far stricter lockdowns (See AU). But even those places are still dealing with the pandemic. In fact, it looks to me like we have two choices - get in lockdown, close all borders and remain that way indefinitely, or open up and move on with our lives.

We can say this much - whatever we've been doing so far has not worked. We should try something else.
HN may be generally curmudgeonly. But at least it comes with a sense of self awareness.
Side-question: what are people using today to copy-protect their software (other than running it as a SaaS)?
Let's take doctors as a specific example.

Suppose we take the Phillipines and Malaysia, they (together) have about 6x the population of Australia. They have the capacity to train a lot of doctors - and a doctor can have a great life in either of those countries.

They can both also produce doctors more efficiently than Australia, partly due to living costs / ppp and population size, and partly due to Baumol's disease hitting education costs harder in AU.

But let's be honest, no country is talent-limited on doctor production. What's limited are training slots, and that is partly a practical concern... but also licensing restrictions - which tend to be regulated by doctors who have a strong interest in avoiding the oversupply of doctors.

What I am trying to say with all this is that there are many reasons someone might not be getting good medical care in say, the Phillipines but those reasons are not primarily due to doctors emigrating.
Evolution of Desktop – Initiative by Harvard Innovation Lab
A well distilled (yet detailed if you follow all the links) summary of good practices for good-thinking-supported-by good-note-taking.

The actual form of the piece nicely serves to illustrate (one of) the thesis it puts forward: that more complex, fully articulated works can grow out of a body of more atomic, partial, linked notes.

I found particularly interesting these assertions:
- knowledge work practices are often ad-hoc (often unknowingly)
- note writing is a core skill of knowledge work
- note writing skill often plateaus because improvement is not ‘salient’
This captures a lot of what I have always wanted to express. I am of same cohort as the author, and aside from being laid off once (which, honestly, was wonderful) I have managed to stay well employed 30 years in tech. I hold no degree. I have no specific super powers. But, yes... everything stated here rings true for me. I would, humbly, add some of my own.

Learn the people patterns. Every where I have worked has at least a few, if not all, members of Typical IT Cast Of Characters. There is the "know-it-all-but-does-not", "wise old sage", "management climber", "new guy", "one-job-and-doesn't-want-to-change", "hockey-jersey-guy-who-smells-but-knows-too-much", etc. Pick your own. Most of these people will avoid, tolerate, get along with, or maybe love the others. Or some combination thereof. I have found being the impartial mediator to be advantageous. Be the "Ferris Bueller".

Know the business as well as the tech. Technologists that can dive into the business language and work with both groups are invaluable.

Diagrams. Work hard on developing the capability to express ideas/concepts/flows in a diagram that fits on one sheet of paper. Do this all the time...even for one-offs. As the author states, it helps build your brand. It's advertising. When I see a one-pager I did 6 months ago on a desk covered with coffee stains, or pinned to the wall above monitor...I know I have made an impression. I worked with a few masters of this craft, and honestly, they are all magic on any team.

Share credit constantly. Don't ever appear that you need validation. Give good ideas away for team members to catch and grow. You will build a community around you that seek you out for guidance. Time passes quickly... that junior dev you credited for a schema re-jig 5 years ago is now a VP at BigCo. She didn't forget. Keep in touch, right?

Religion was -at that time- just defining social norms, like the government defines them today (the church got kicked out at some point then, because science proofed them wrong with many things). If everyone lives by "rules A" (and are convinced those are the right rules, e.g. "don't lend money"), then just living by a different/opposing set of rules is asking for trouble.
> now almost every single piece of software has an installer that's at least 500 MB large.

First, that's 500MB initially. It goes up from there.

Second, that works only if a small number of apps are bundling Chrome, and RAM can keep up; once too many Electron apps promulgate, people will start installing fewer apps.

> which is so obviously a quantum leap in terms of what it could do for human productivity

that's a very strong claim. and it's very likely, unfortunately, false.

we have the great classics all available for free in a multitude of formats. a lot of works slowly but surely mature into the public domain each year, yet there's no discernible productivity growth based on the availability of books.

also, this sadly goes for research papers too. sure, fuck Elsevier and the whole paper mill industry, but the limiting factor is expertise, tenured spots, academic integrity. (see the replicability crisis in psychology, in particular how the many times the whole scientific enterprise is backwards: https://statmodeling.stat.columbia.edu/2011/01/11/one_more_t... and https://statmodeling.stat.columbia.edu/2016/09/21/what-has-h... )
That’s not the experience I’ve had. I have shown it to people who were not into category theory who got it fine. Also it goes beyond CT, CT unlike say linear logic isn’t closed under norm.
