P4 language. Truly defining networks via software is currently and will continue to be amazing.

I was going to jump on here and say that. P4 combined with P4 target ASICs (like Barefoot Networks) will be a really awesome change to networking.

I'm entering radiology residency, and I'm very pro-automation / machine learning. There's a contentious debate in the field about whether radiologists will be replaced: https://forums.studentdoctor.net/threads/will-ai-replace-rad... HackerNews is very developer-focused. If you guys saw what a radiologist does on a 9-5 basis you'd be amazed it hasn't already been automated. Sitting behind a computer, looking at images…

Wow. It is crazy how uninformed you all are (no offense). Radiologists do not just look at an image and say "white thing there!". They incorporate the appearance, characteristics, anatomy, pathophysiology, patient's clinical history/age/medications/surgical history, and combine all of that information into some image findings but more importantly a focused differential diagnosis for the clinician. We have had computers reading EKGs for decades (a 2D line) and they still get it wrong 50+ percent of the time. No machine is taking over EKG's any time soon.

I'm sure machines will someday take over radiology but there will be many, many jobs automated before it (i.e. decades).

>I believe the biggest advancement in the field of education is going to come with VR I'm 100% with you on this. I've been saying this since VR became mainstream, I'm dying to start something in the e-learning space that takes advantage of VR/Augmented Reality but have no idea where to start.

Here's an odd, tiny, somewhat controversial/dangerous-sounding yet possibly interesting idea I thought of a little while ago that you might like to play with: a road-crossing simulator/trainer (and related concept areas). My house fronts onto a small but fairly active 4-lane regional/suburban highway which I need to cross whenever I get the bus home, and also sometimes when I leave depending on which direction I'm he…

Have you ever played the old "Frogger" video game?

fancy words, exciting claims, and absolutely no detail whatsoever. with all due respect, said politely, it is my opinion that you are a charlatan.

>fancy words, exciting claims, and absolutely no detail whatsoever This is true of basically every post in this thread. If you're interested in learning more, there are more friendly ways of asking.

No, it's not true of most posts in this thread. Many posts in here have details. Admittedly, not enough to take the audience and make them expert enough to understand the breakthroughs. But enough to show there is something real being described.

Re: friendliness -- I believe I expressed the opinion that someone is a charlatan in as friendly of a manner as is possible.

Sounds interesting. Would you care to share any references?

Most certainly. This current work I am doing builds upon the mountaintops of huge amounts of work built by two men who base their work on yet more huge foundations. Igor Ledochowski - http://hypnosistrainingacademy.com John Overdurf - http://JohnOverdurf.com As far as context-free therapy goes, that's a bit of an advanced subject, but can be learned and mastered through some of their programs.

It seems like the missing step, right between 3 and 4, is "and then a miracle occurs."

That's why I made my original comment. Maybe you're not a charlatan, in which case I'd have to conclude you're thinking irrationally and have been deceived by some form of magical thinking.

You have not proposed any mechanism by which these steps can form a consistent treatment for problems that individuals have struggled with for years. You've merely declared that it will, and a whole lot of faith is required.

Other posts in this thread mostly propose a mechanism, even if we readers don't have the prerequisites to fully understand it. For example, consider the proposal that machine learning could be applied to the mundane tasks a radiologist performs. It may or may not pan out, but it has a basis.

My field is web development, and, to be honest, the most exciting thing going on is that more people are starting to complain about the complexity of development. Hopefully this will lead to people slowing down and learning how to write better web software. As an example, one survey ( https://ashleynolan.co.uk/blog/frontend-tooling-survey-2016-... ) put the number of developers who don't use any test tools at almost…

There's a market imo for a full solution that includes front end and entire backend including deployment, seemless scaling, seemless upgrading, seemless backups, seemless local dev, seemless staging, etc. 99% of web apps need the same features but most of this is still up to manually rolling your own. I should be able to clone some repo, enter some DO/AWS/GOOG keys and push.

I've been using and loving Zappa[1] lately. Basically it lets you seamlessly deploy a flask app to AWS Lambda -- that solves your deployment, scaling, upgrading, staging, backups, etc. And local dev is just running the flask app locally.

What's the unlimited thing?

It has to do with the need for increased block sizes. Right now, each block (chunk of validated transactions) can only be 1MB in size. This restricts the total throughput of the network, but keeps the total size of the blockchain down and the growth rate low. The original expectation was to gradually increase the block size to increase capacity as more users joined the network, eventually transitioning most users to…

Thanks for the great explanation! So where does segwit come into this?

I'm curious why this has been voted down.

Probably because it's not VC-fueled hyper hyped. And doesn't fit the current mainstream pattern of "world changing technologies", etc.

I see. I've seen a couple people recommend it now, I'll have to give it a look at some point.

I've heard it consumes a lot of memory which may be a problem though (this laptop only has 2GB RAM).

I'm not the best person to ask, and I don't fully understand segwit, but I think it's the Core devs (partial) solution to the problem of scaling up the network without increasing block size.

IIUC, segwit makes certain kinds of complicated transactions easier to handle (ones with lots of inputs/outputs), possibly allowing more transactions to fit in less space, and lays useful groundwork for overlay networks like Lightning. I think the thinking is that overlay networks can be fast, and eventualy reconcile against the slower bitcoin network.

Unlimited would rather just scale up the bitcoin network in place, instead of relying on an overlay network.

You'd probably get better information from bitcoincore.org and bitcoinunlimited.info, or the subreddits /r/bitcoin and /r/btc (for core and unlimited, respectively, they split after moderator shenanigans in /r/bitcoin).
