Robotics requires both and neglecting either one will give you bad results, if you even get results.
Issues in hardware can be solved in software to some degree and vice versa some things that can be hard to do in software can be solved with better hardware.

You can certainly get started on robot software when you have some ready-made hardware. You will not learn how to build your own robot from scratch by skipping that part, obviously. You will likely not make a successful robot business case with just buying hardware off the shelf without understanding it well.

This reminds me a bit of Larry Niven's idea of breeding for psychic luck in his Known Space stories, in which Birthright lotteries are held which gave the winners the chance to have children.
So, if wealth is indeed due to luck, one could make the whimsical case for luck being heritable.
And indeed, it seems that the world's wealthiest tend to have more children, on average, according to this article:

I've worked with Ruby in the past and I currently work with Python and Elixir. This is a caveat that Elixir inherited from Ruby. In Elixir there's the `only` option of `import`, but it doesn't seem idiomatic to use it. In Python there's `import *` but it's an actively discouraged practice whereas in Ruby and Elixir it's the norm. I like all three but on this particular point I think Python got it right.

What's more curious than the irreducability issue is, how on earth does the syntax ever get accepted by the parser?

I mean the lex/yacc syntax has to reflect the nestability of the while/switch [1], ditto if you do recursive descent, so how is it possible this even parses?

Perhaps it is not current usage, but I guess it might have be common English usage till 19th century. I think that I have seen corn used generically in novels and other works from before that time.

If there's an epidemic starting, then only a small number of people have the disease. Everyone wearing a mask would help, but if you have a limited number of masks, you want to focus them on people likely to have/catch the disease.

The masks worn by people without the disease would be ineffective or even counterproductive if health care professionals were missing PPE as a result.

Problem is, the device doesn't have to know, which address is the working one - e.g. which prefix is working on the upstream. It might break connections etc.
A solution of course could be to have NAT66 and I really mean address translation not masquerading/ port translation here - as such, much easier to do as it is a 1:1 mapping or to get provider independent space or become a LIR and have two providers announce your space with respective BGP configuration for failover.
It is a solvable problem but isn't much guidance and experience with this at smaller companies that might not want to run BGP or go through hoops to get PI space etc.

Ah, indeed. I invoke Poe's law. :)

Though I'd argue this is not the place for such comments. It only further perpetuates the lowbrow "discussion" on a very sensitive topic that, if nowhere else, this forum should be above of.
Never mentioned anything about 'the banks' but regardless, they are still around because everyone needs to eat and you can still pay for your groceries with your card linked to your bank account which payments provide very low transaction costs and it is still fast.

Unlike Ethereum which it has gotten worse to use over time to the point that it is useless to pay for your groceries. Perhaps there are other blockchains that are better for both for setting up DAOs and paying for your food.

Oh dear.

So why were they clockwise?

Here's my guess. Falling down a staircase is way worse than falling up it. If it's clockwise, then if you hug the outer wall (with the less steep steps) as you go down then your dominant hand can hold the wall (and any handrail).

Sorry that really doesn't add up to what I see when I look at job boards, Elixir has really poor numbers. The Ruby guys who wanted to jump ship to Elixir already did so a few years ago (some of them will continue to jump ship from Elixir to Rust or Go because hey why not). So I don't know where new growth will come to Elixir.

It's not just jobs, by any metric you can think of Elixir is an obscure tech, if you want I will add sources to this claim but hopefully we can agree.

Although I am not entirely certain, he maybe did hold a grudge. His two other students knew about the move since June, but never shared. This news was broken to me on Nov 5th, 2012. This was not about performance. I had published a journal paper in my doctoral second year, wrapping up a VR project in 2012 (in a decent journal) and was 3.8+ in grad school.

As you could imagine, it was terribly ill-timed for me. I could not transfer to another school. Good schools within the same standing all had deadlines between Dec 1 & Dec 15. GRE applications can take up to 6 weeks to be forwarded. I was dirt poor. My semester fee would have been $11,000 for Spring. I couldn't have paid it. No professor in a niche area as computational imaging, would take you at such a short notice. If I am unenrolled, I was effectively out to the starting line. By this timing, I have a feeling he set me up to fail in the end & crash out.

He did sign the thesis (that would have had been a red flag to the department). He however withdrew financial support immediately effective that day, and didn't accept to be co-author in my journal paper[1] - just me and my pair-coding partner.

It's possible that success isn't determined by something that's normally distributed like intelligence or hours worked. Say the key factor is what they call "grit" or determination. If this occurs according to a power law instead of a normal distribution, you could have a situation where the average person has a score of 0.1 and an all time determined person has a score of 1, or 10 or 100.

We can see easily that no human has an IQ of 10x the average. But determination to accomplish a goal is difficult to measure, empirically or subjectively. I can't really say that super rich person X didn't just want it 10x or 100x more than everyone else.

It's interesting that the authors were able to come up with a simulation that roughly matched real world wealth distribution. But there are a large number of potential factors that they did not and could not account for in a model. I fully agree with the idea that all great wealth comes from luck and chance in some form or another. This article is definitely stating what I believe to be true. But I don't know if they really proved anything.
Good story!

Everyone were correct about being afraid of opening CRT monitors. Repairing them is a whole other domain than PC electronics. A CRT ZAP from the cathode ray components can kill. That is not a place one should poke around trying to find solutions.
Well, it's a personal blog about a subject. It is information, sources and prose, really anything the author finds interesting and persistent to the subject.

If a particular myth has a particular following in any identifiable subset of the society, that's interesting to me. In particular, just before the passage you question, the author states

> One reason for [resilience of this myth] might be the frequency of its repetition by parents to children.

so a casual observation about it being more of a father-and-son thing is permissibly relevant in the context of a blog. And it sounds like this guy spends a fair amount of time around castles. You might disagree with it, you might argue it is due to biases involved in raising children, or other things too, but sexism it is most certainly not.

If society is a lottery, then the smart move will leave you sliggtly better off than the gamvlers, but not as rich as the guy who takes the gamblers losses.

I don't own any DOT or ADA, don't plan to, and don't know anyone who works at either Parity or IO-HK. In fact my current crypto holdings are like 100 bucks in `ETH` left over from buying some dApp thing.

What possible motivation could I have for shilling a coin?

You're better than this, and HN is too.
The natural form for aviation fuel is liquified hydrogen, LH2, sidestepping worries about embrittlement. LH2 is so much more efficient as an avaition fuel, despite problems handling ultra-cold liquids, that kerosene-powered aircraft will be simply unable to compete anywhere LH2 craft are in use. The rate of collapse in value of kerosene aircraft will be limited only by the rate that we can build out new or retrofitted LH2 aircraft.

It is not clear whether existing aircraft or designs can be usefully retrofitted for LH2. Existing wing tanks are, in any case, useless for LH2. You need much more room for LH2 tankage, and you might not want a big LH2 tank inboard; there are safety reasons for the fuel in current aircraft being out in the wings. So, maybe the LH2 is carried in nacelles slung under the wing, next to the engines. We will need to build up a great deal of aerogel manufacturing capacity to insulate them.

It is possible that existing wing tankage can be used to carry NH3 to inject, in small proportion, to minimize NOx pollution. Given a bit of surplus N, the N prefers to make N2, and the O prefers to make H2O. E.g., existing natural-gas plants inject NH3 to reduce their NOx output.

For shipping, anhydrous ammonia is probably a better choice of fuel. Existing engines can burn it, so you need only new room-temperature ammonia tanks and new plumbing.
> Cause (in case I’m smart enough at all) I have no courage to risk and implement a working thing by myself

The risk of the same action (e.g. spending a year on getting a startup to work out) differs based on your background, too.

Let's say you make minimum wage. That reduces the amount of money you can invest in your startup, lowering the chances of success while also shortening the runway. The risk here is might even be homelessness.

If you are backed by a reasonably wealthy family, you can invest more and your runway is longer, making it more likely to succeed (or at least fail not that hard). The risk here is having "wasted" one year of your life.

This doesn't even take into account other factors like family/friend connections.

Of course there are always counter examples to this, I'm just talking about probabilities.
Survivorship in what sense? The castles that exist today have not survived because they were better at repelling swordsmen, they survive because someone in the nobility happened to like them and protected them from development and hundreds of years of disrepair.
Arg, so true. People that assume everybody is more stupid then them are the worst. I have friends (that sometimes are on the verge of not being friends) that always remind me what a huge responsibility a puppy is when you show them pictures of new family member, or that your mortgage is so high you can't travel anymore and you have to have priorities in life, "you have to be able to enjoy it too".

Assuming I'm to stupid to think for myself is the most insulting thing you can do to me. Sadly I still can't respond to this behavior properly, I get so worked up, it messes up my day. It even causes me to complain about it on HN.
Why? The core value proposition is still there, be able to do transactions between parties that don't trust each other and prove that double-spending didn't happen.

Not every kind of "smartness" is rewarded on the job market or on the market in general. As a hired employee, I am 5x wealthier than a couple of my peers who enjoy solving a Rubik cube in 20 moves, or excel in IQ tests. It takes a bit of social aptitude and common sense to approach the right social circles, to present yourself in a likable manner, to reason in abstract terms.
Everything makes sense in the end. Whats actually important is the stuff between your ears and the health of you and your dearest ones. Money and age are just two numbers that dont mean too much.
The fundamental power of the internet is its interoperability. It was born out of the ability of different networks to talk to each other using common protocols.

The interoperability is what we've lost in the Web 2.0 era. Even such quintessential thing as a web API has no well defined standard or protocol, just a very vague concept of REST or RPC.

I want Web 3.0 to get interoperability back. We badly need commonly accepted standards and decentralized protocols: for web APIs, for identity management, for message queuing, for web callbacks (webhooks), for online transactions, for semantic web and ontology, etc.

Take, for instance, web APIs. It's barely usable nowadays. Imagine if you had to write a special browser every time you need to connect to a new website. But this is what already happens with APIs. Accessing programmatically any web-service requires custom coding an API. Insane!
I have a custom app which monitors my device 24/7 in the background with a persistent WebSocket connection to my server to receive push notifications. While yes, as a user you need to grant some permissions to the app, it works without a problem.

If by notifications you are referring to Firebase Cloud Messaging, which replaced Google Cloud Messaging and is now integrated in Google Play Services, I do agree with you.

It is my opinion that Google should be forced to decouple all these Google Play Services which are not related to the "Online App-Store" which Google Play is, and ideally be forced to open source it, so that trustworthy alternatives can be used to replace it.

I mean all the components which track you, which basically is what Google Play Services is: it is a system service created to monitor every possible activity you have with your phone (location, physical activity, health) as well as the efficient, persistent data connection to transfer these bits of information to Google (and to your device as FCM), while Google grants you access to use these services in a restricted manner.

For me Amazon's Android devices are basically useless since they don't have Google Play Services installed, and you have to work around it to get it installed, which basically is illegal to do.
Not exactly. Timing is the issue when it comes to mixed type of data sources. try to load data via the URL (e.g. the results of API invocation or rss feed), then merge it with the data from postgres sql table or data from CSV file. It becomes challenging with the listed tools. Whereas TABLUM.IO solves the issue and make it organic and fast.
And as the article itself mentions, if it's down to that level of desperation you've already lost. I mean the attacker can start a fire to smoke anyone upstairs out, or continue the siege and just wait.
If I were an attacker, with the defendants stuck in the tower, I'd probably just shut the door at the bottom and wait. Maybe start a small fire at the bottom and let the smoke do the rest.

No need to get messy on the actual stairs.

You are confusing something. Are you talking about the country that started nearly any war in the recent past, failed to win or loose it and just stretched it out for years while killing thousands of civils for the good? The same country that somehow managed to break the Geneva convention regularly, especially with things like Guantanamo and have no excuse at all? All in the name of spreading democracy, something they not manage to actually implement themselves?

From my POV America is the one country we need to be most afraid of. Mostly because their irrational, war driven, and human rights ignoring behaviour all around the world. Not just in their country
The Catholic Church almost became so cool during the Renaissance. The history of Ficino, Pico and the Medicis is fascinating. Pico wrote the first banned book — and then the papacy actually opened up quite a bit, but then started going dark really quickly.
20th century mechanical engineering is a "solved problem". i.e. designing products to be manufactured with milling, bending, turning, welding, injection molding etc.

21th century mechanical engineering primarily involves novel manufacturing processes that massively increase design flexibility while making manufacturing extremely expensive.

Most people don't need the state of the art, they need affordability. Meanwhile semiconductors get cheaper every year. There is more opportunity on the software side.

You're also forgetting that it's a MOOC for ROS2, not "the field". If you've ever been at a college you notice that you don't learn "the field" in a single course.

I run a SaaS service and noticed we did a couple of these 'dark patterns', but not intentionally!

I've now added to our short term roadmap changes that will resolve these problems.

1. Emailing account holders a couple of days before billing to give them an opportunity to cancel.

2. Emailing account holders whenever a change to their account occurs which would affect billing.

This wasn't us being 'dark' more 'lazy', but thanks for highlighting!
