zcw100··on College Tuition Is Marketing Fraud
What exactly did you think gen X was going to do about it? How many gen-x-ers do you think were on the board of any of those schools? When they were out voted at the ballot box? Being encouraged to drop out of college because the dot-com boom? When they were encouraged to buy homes at massively inflated prices with zero down and variable rate loans that then crashed? After 9/11 and during 20 years of foreign wars that they went to fight?

I don't know any other business that quotes an outrageously high cost then says, "Well, let me see all your bank accounts and I'll let you know what it's really going to cost you", then gives you a kickback. It is designed to extract the maximum from every customer. If you've got the money, they're going to take the money, otherwise they're going to take all that you've got.
zcw100··on The AI Unbundling
This reminds me of the early days of the synthesizer. Oh, no. Music is over. First it was novel and interesting, then it was poorly done and cliche and then the artists did what they do, they turned it into something new and fresh and then it was awesome. Same story, new tech. I'm just keeping my eye out for the Stevie Wonder of SD.
zcw100··on Stop Hiring Software Engineers
I couldn’t help slipping into reading this in the voice of David Attenborough. “If you look in under the jungle canopy you just might catch a glimpse of the elusive product engineer. Festooned with their hoodie and mechanical keyboard. What a rare and magnificent find!“
zcw100··on Electric vehicles will have to wait for the solid-state battery ‘game-changer’
I wonder how much of this is the technology and how much of this is, “don’t hold off your purchase of an EV because you’re waiting for new battery tech”. It makes me think of the latest iPhone announcement. There’s lots of complaints about it being only incremental improvements but making radical improvements has its downsides too. If you think a radical improvement is right around the corner you’re not going to buy and try to time your purchase. With steady improvements you can buy in whenever without worrying about the timing.

It sounds more like IPFS
zcw100··on Design and evaluation of IPFS: a storage layer for the decentralized web
It is when you don’t include any context. You at least included that your standard of performance is a raspberry pi.

That reminds me of a similar game, Miegakure. Not hyperbolic but 4D. It looks sooo cool https://www.youtube.com/watch?v=9yW--eQaA2I

zcw100··on Sierra Club, environmental groups petition EPA to ban natural gas for heating
I agree with most of the comments about how ineffective this would be and the numerous problems it would cause but to provide some balance this is not some edict, or even law. Two dozen organizations "petitioned" the EPA. This is the equivalent of sending a strongly worded letter saying, "Could you pretty please do this?". It can and probably will go straight into the trash.

These are environmental organizations, of course they sent a letter. That's what they do. They'll also probably get a letter from all the heat pump manufacturers saying they're cool with it, and other letters from people selling natural gas and gas furnaces. I'm sure they'd like you to stop cutting down trees and that ain't going to happen either.

zcw100··on Design and evaluation of IPFS: a storage layer for the decentralized web
1. IPFS attaches ALL network interfaces (internal and external) to your identity.

I don't know what you mean by attaching a network interface to your identity or even just identity. IPFS identifies a node by PeerID which is mostly a public key, that's it.

2. Tor is still "experimental" done by 3rd parties. https://flyingzumwalt.gitbooks.io/decentralized-web-primer/c...

Tor has nothing to do with IPFS. There have been some people that have worked on some integrations to use them together.

3. Due to 1 and 2, any hosted content is EASILY trackable to a user's computer,even behind NATs. A machine cryptokey also helps cement that (but can be changed). This allows easy DDoS'ing of any and all endpoints hosting content you don't like.

Yes, it is easily trackable. There is nothing about the design or goals of IPFS to be anonymous. In some ways the entire point is to be found and announce that you have content available. I don't know why people associate decentralized with anonymous. Not sure how you think it's cemented. Just toss the key and make a new one. How does this make DDoS'ing endpoints any easier than anything else hosted on the internet let alone DDoS'ing all of it. In face being distributed and content addressed can mitigate DDoS if it's malicious or just a hug of death.

4. It is trivial to ask the dHT for who has a certain content key, and get all (or the top 50?) computers hosting that content. (this matters with regards to "sensitive" content)

I hope so, that's the way IPFS works. Ask for who has what you're looking for and retrieve it. I have no idea what you mean by "sensitive" content. If it's sensitive you can encrypt it.

5. Running a node is still high cpu, ram, and network chattiness - so using a VPS to keep IPFS off your local network is still tenuous to run.

There are configurations to mitigate this but just making a blanket statement that it's high cpu, ram, and network is just FUD.

zcw100··on Toyota patents plans for EV with manual transmission and clutch
I love driving manual transmission cars but I really don't like this. It's like cosplay for cars. The simulated experience makes it very uncool. I'd rather just let the manual transmission have one last dignified drive into the sunset.

Why is that?
zcw100··on Smartphones are disrupting the crucial connections between parents and babies
This says more about parents anxieties about the world than anything about raising babies. And what’s going to mess up kids more than any electronic gizmo? Parental anxiety.
zcw100··on Metra to create battery-powered locomotives
I never understood why trains don’t use regenerative breaking like EVs.
zcw100··on Price of FSD will rise to $15k in North America on September 5th
Why not? Everyone knows that when you’re running a scam and things get rough you don’t back down, you double down.

The guy just got a free $7500 courtesy of the tax payer for every car he sells.

zcw100··on Ask HN: Is it time for AI to start replacing doctors?
This is a profound misunderstanding of both healthcare and the current state of AI.
zcw100··on Why don't we do email verification in reverse?
Because it’s easy to fake email from your account.

zcw100··on Programming breakthroughs we need
How about, it is quite bizarre how people who employ programmers, who make billions of dollars per years, are unwilling to pay $1,400 that will make us more productive.
zcw100··on A Letter from Ken Snelson Regarding Buckminster Fuller and Tensegrity (1990)
For something like a rubber band the challenge is that it will tend to pull itself apart before you get the final band attached. For cables that don't stretch the challenge will be it will be a gigantic tangled mess until you tension it. I have no idea how Snelson managed to construct the larger sculptures without killing himself.
zcw100··on A Letter from Ken Snelson Regarding Buckminster Fuller and Tensegrity (1990)
You can get started with some rubber bands and soda straws. You just need a lot of patience. That will get you started but there are a limited number of things you can do with that and the rubber bands won't last being under constant tension and will eventually break. It takes a surprisingly small amount of materials, just something for the struts like dowels and some string. The most difficult thing is choosing how to attach the strings to the rods. It takes a lot of adjustment to get the pretensioning correct so you need something that you can change until you get it where you want it.
zcw100··on A Letter from Ken Snelson Regarding Buckminster Fuller and Tensegrity (1990)
I've had fun building several tensegrity sculptures and I agree that it makes me very wary about bridges built on the idea. They have very unintuitive properties that are difficult to appreciate by just looking at them. They appear to be rigid but are actually springy and without pretensioning they are a floppy mess. It seems to be very non linear too with the structure lacking any rigidity as you tension and then snapping into place at the very end.

There are some very interesting similarities between tensegrities and bio mechanical structures. I used to think of bones as the scaffolding that holds up my meat parts but it's more like the meat parts and the bones work together as a tensegrity structure.

Because it's the junk drawer of the internet.
zcw100··on Petnames: A humane approach to secure, decentralized naming (2018)
There's a link in there for it but it would be easy to miss that does a much better job of explaining the system

http://www.skyhunter.com/marcs/petnames/IntroPetNames.html

A pentane system actually protects you from phishing attacks and you don't really share your pentanes. You can use your petname as a nickname when introducing a key to someone else. One of the most important parts is to have a good UI/UX that does not confuse nicknames with pentanes or allow you to accidentally accept a nickname as pentane that is confusingly close to an already existing petname.

Nicknames are names that you propose using when introducing yourself or someone else. A pet name is the name you assign privately. So Lumberg could be a nickname but your petname might be "dickhead boss". You're free to introduce him to people you know either way you'd like.

zcw100··on Vector search just got up to 10x faster and vertically scalable
Same difference as ElasticSearch and Lucene.

zcw100··on I hacked my car
I wish that I felt comfortable hacking my new $50k car but I’m glad you do. I usually break stuff I hack.
zcw100··on Ask HN: Aging and learning. Does it become more difficult?
Biologically, maybe, but only a little and it won't explain the feeling that it's a lot. I don't think it has much to do with any age related cognitive decline and mostly to do with more responsibilities, more things competing for your time and an objectivity that causes you to have different priorities.

As I've gotten older I've only had more and more things competing for my time. I have a family, a home, hobbies, etc. I just can't devote hours and hours of uninterrupted time. With experience there's a lot of "ain't gunna need it" and if I do I'll learn it then. I've got plenty of stuff that I sank tons of time into in my younger years that only faded into memories and didn't turn out to be very useful.

As far as tech goes you'll see enough stuff come and go that sinking that much time into it will feel like a waste. Remember SOAP, SOA, XML, XSLT, EJB, CORBA, MapReduce, Mesos, Java Applets, etc? A lot of what you're doing now is going on that list.

zcw100··on No More “Insight Porn”
“It’s advice that sounds plausible and breaks down a goal many people dream about into actionable steps.”

Sounds like scrum.
