>where power generation and internet is lost you lose access to BTC

You don't need the internet nor the power grid to use bitcoin.

To use bitcoin via the Lightning Network minimally, you need a CPU and a method to transmit data.

CPU: phone

Transmit Data: Bluetooth, QR code/camera.

Electricity for your phone: Cheap emergency solar panel
For screener I use finviz and for protfolio tracking I use Yahoo Finanace (they actually have a solid app).
But you trust your mobile operator more? Pfft.
> It's pretty remarkable that the transaction layer (Lightning network) on top of Bitcoin hasn't garnered any discussion in this comment section

I would say it's pretty encouraging since it barely works, doesn't deliver on any of its promises and much more convoluted to use that normal crypto-currency.
I'm not so sure. This implies that there's some reliable stability in life to which you're holding on to, so when you take risks, you're discarding this reliable stability.

But I don't think this stability actually exists. Lots of things can turn on you and your family at any moment, and then you are not ready, because you haven't been taking the necessary risks, haven't been taking care of yourself, out of a sense of duty.

I think people generally function best when they optimize for themselves compared to optimizing directly for others, because if you do not optimize for yourself, you rot, and then you cannot help said others anyway. Optimizing for others can be very difficult and inaccurate. Put on your mask before you put on your child's mask.

Optimizing yourself should already take care of unnecessarily rash YOLO decisions since you wouldn't want to be left without any money yourself, either. But holding on to awful positions out of a sense of duty, ehh, that seems to be how people get to a really bad place (i.e., depression, alcoholism, infidelity). And, ultimately, there's not just duty to your specific family, but also to society, and you can't change society when you are always just going with the flow.

It also creates a rather sad picture for said family.
Algo supports it, without being super-obvious about it. When it's done doing its thing, fish out the generated wireguard client config from

algo/configs/your.server.ip/wireguard/uname.conf

Add

PersistentKeepalive = 25

as the last line (should be in the [Peer] section).

Feed the conf file to your client. That's it.
The keys to success are your social connections to capital and your acting skills; that's it, nothing else matters. Find a rich person, get them to like you (the difficult part), then get them to invest in your startup. Then you'll succeed. The richer your friends are, the more likely you are to succeed. However, it should be noted that the richer your friends are, the better your acting skills need to be (competition is tough).
I don't know about the next big innovations that will be widely adopted, but I think I know that if the following innovations happen, they will probably be widely adopted...

- Applications that aren't slow: "In a world where an app opens right when you click on it".

- Fast websites: type in the url, hit enter, and you're in. You click on a link, and voilà..

- Split second boots.

- Chrome not killing my computer when opening too many tabs (I used to open 120+ I think with Firefox).

- Make sbt not download the whole internet (yes, cache and all).

- Printers that actually print when I want to. Also make printing in black not require other colors.

- Automatic transmission cars that don't do a jerk motion when they stop.

- Universal cartridge format.

- Time tracking app that magically monitors what you do during the day without your intervention and can show you a treemap. Over the years, you can learn something.

- A huge dataset on every company and human that was ever formed and its life through success or failure. Maybe we can learn from that.

- A way to encode and distill the whole human knowledge. A graph of "knowledge" of sorts.

- Peer review that works.

- Time management, cognition, meta-cognition, deliberate practice, empathy, cognitive biases, and how memory works lessons in primary school.

- Voice calls on (Skype, Viber, WhatsApp, Messenger) that sound like a phone call.

- A way to simulate your life with varying parameters and find a path to a desirable outcome.

- Natural computation: A billion objects falling don't require nature to spin up more VMs to handle all their trajectories and write a Medium post about how it did it. Physics seems to handle great loads, concurrent events, several processes mutating the same object simultaneously, out of the box. A computer that does that.
Why didn't the Adhaar creators not go with PKI like Estonia did?
This is just wrong. They found that out using Google search and social engineering. A lot of his details like his phone number were available online and were available with a Google search. Amazon, being stupid, uses a copy of Aadhar as an authentication mechanism. The Aadhar number is not supposed to be secret. That's the reason you need to use biometrics along with your number to authenticate you.
I've asked this elsewhere in this thread and tried to google it but didn't get/haven't gotten an answer, is there a reason Adhaar did not go with PKI to provide identification and signing? Did they have some extreme not-invented-here syndrome?

I think we'd probably all be using private/decentralized identity systems if it wasn't for KYC/AML regulations. The problem is that decentralized and some private identity systems are all "vulnerable" to pseudonymization, so it make KYC/AML impossible.

Hmm. This seems like one of those things that may be statistically true, but the statistic may not be relevant to a given situation. I think there's a term for stuff like this but I forgot it, regression to the mean, maybe?
I'm always amazed at how wasteful such experiments appear from the outside. You have two well educated people building a fancy machine to break spaghetti into two pieces instead of three. Pause and take a moment to reflect on how silly and wasteful that sounds. I'm thankful for the brief section on "What possible application could this have?" although wish it went a little more in depth in how it could help build carbon nanotubes or how it might help future engineering projects. I can appreciate that this research likely has greater merit than "answering a silly question".

The paper is in the article - but for those more interested in the research paper: http://www.lmm.jussieu.fr/spaghetti/audoly_neukirch_fragment...

Why? Certainly my MVC apps have a single "store" that's the source of truth, and I would say that what you describe is not following the MVC pattern.
Huh. Think I'll package udptunnel for Arch and fix up the ArchWiki entry with this. Super neat.

I experimented with anki in law school one semester.

I decided to feed all the concepts of my criminalistics class into the program and only study that way. The class contains a lot of procedures and tidbits you kinda have to memorize (It was a bad class, I think it should've been taught entirely different but that's another subject).

I came out GREAT. I aced the fuck out of that class and I didn't even have to use anki every day.

So you hardly know the languages, never used some of them, but Go compiler is faster.

Very scientific.
I haven't seen it in my texts, and actually perusing the dictionaries and sign-lists right now, I think I'm getting a sense for how the derivation came about.

I modern reading of the signs that make up the word they're talking about "irrû" in Akkadian, are: ḪUL₂.GIL₂, but the context of its use suggests a bitter cucumber like plant (also a tangled plant, because "irrū" means intestines).

As to the name "joy plant" if you were to read the signs as ḪUL₁!.GIL₁! (notice the 1's) then that would be correct, but instead they are the second versions of each sign, and cannot be read as "joy" or "plant".

Yes, you can build a simple house like that. But what if halfway through the construction, the client says they want the bathroom on the other side of the house? You'd have to redo (e.g.) all the plumbing from the ground up, location of the heating system, walls, doors, perhaps even staircases ... etc. etc.
I've been on some before but never seen a code review job post, but yeah that's a good idea and I guess that would work.
Hard to say, which is why I was kind of hoping for a site dedicated to this kind of thing. ddorian43 is right though, I suppose I could just use a freelance site.
Even in the days of the print media, the user was the product. The real money wasn't in subscription prices, it was in advertising. I don't think that much has changed.

Fedora regularly rebases to the latest stable kernel, usually by .2 or .3 release; but 4.18 has had quite a busy series of rapid fire updates, so it's already at 4.18.5. I expect to see that in Fedora 27 and 28 updates-testing this week.

Usually it's possible to get a build of current stable or mainline kernel in a day or two on Fedora, through koji. And through updates-testing repo (opt in) a few days later. And through updates (enabled by default) anywhere from 1-5 days later. The system depends on testers using updates-testing repo to give +/- points to each tested package, and the kernel comes with a higher than usual minimum number of points and time delay to avoid regressions.

You can (manually) install kernels in Koji which don't always show up right away in the updates-testing repo. So you'll see 4.18.5 there for fc29 which can be installed on Fedora 28 (I've been doing this for weeks). And you can also manually install 4.17.19 which is already built there, just not yet in updates-testing.
https://koji.fedoraproject.org/koji/packageinfo?packageID=8

4.17.18 has already gone stable in the updates repo, so anyone doing a 'dnf update' now will get it.

He voted for the Military Commissions Act of 2006 and against the Intelligence Authorization Act for Fiscal Year 2008. At best his record on torture is mixed and clearly despite all his talk against torture and even his sponsoring of one anti torture amendment (McCain Detainee Amendment to the Defense Appropriations bill for 2005) he still supported it later in his career. Those are facts. You haven't provided a single fact in your response, just an insult that alludes to unknown alleged "facts."

McCain was a war hawk who voted for both the Iraq and Afghanistan wars amongst others and constantly supported overthrowing other governments by force. To support a war like Iraq was unconscionable. Everyone knew the allegations that led to to it were bullshit without having any access to classified information. It seems the idea of a hero here in America is one who goes and sends others to die in war for no reason, without thought, without any consideration for the massive loss of human life that entails. These aren't wars of self defense like WWII, to address your question above, they are wars of aggression, hate, cruelty, and racism. Yeah that sure makes a real hero, killing and sending others to kill for a hateful, cruel agenda.
Readlang sounds quite promising, I will try it for my Spanish! Thanks for sharing :)
That is part of the point I am making with my sarcastic remarks in this thread: too many things go "by default" or by "obviously". Too much implicitness.

Hence the validity of most "successful people advice" is close to nil.
It's a nice enough guide but its default set up is something 97.30133% (recurring, of course) users aren't trying to do with a VPN - reach a home computer from their server. What most people want is to shovel all their client's traffic through the server. This is also described as a sort of afterthought, but I think for most people, it's the thing they're trying to accomplish when they want to set up a VPN.
Science isn't a noble and pure endeavor. It's just a methodology to construct predictive power from information.
They've now moved on to clickbaiting.

Yeah I'm not interested in what they have to say.
I agree with you that this is not the best system, but I think its still better than any that was currently available. Earlier everything was linked to your drivers license, ration card, passport, etc which was also equally easy to fake and less secure. Now with biometrics and SMS based 2FA, its at least more secure than the previous authentication mechanism.

With an authentication mechanism intended for a billion people, which include some of the most poor and illiterate you have to have a balance between security and ease of use. This is unfortunately a compromise, but should at least be x times better than the previous standard.

> Imagine the horror for people who lost their SIM card; to get a copy of SIM they need the SMS code which was sent to their registered number; wait for it.. which was lost.

Oh, please. They can go to the store and use their biometrics to get a new card. That's how I got a new sim card when I lost mine.
> I mean, what advantage does it have over gold?

It's electronic. That is the only advantage, but it's a huge one considering that virtually all (yes, virtually all) money transfers are done electronically today.
My argument holds for gold as well. Do some research on ROI for gold against the stock market for the past 80 years. You will find that it has a pitiful return when compared to owning stocks. Gold is a non productive asset, just because people buy it when there is a market panic doesn't make it a wise decision (people do dumb things during market panics).

If you hoard gold you also run the risk of someone finding a lot of gold and ruining your investment. It's a commodity just like coal, copper, or wheat. If someone told you to hold all of your money in coal, the advice would be just as valid as those who tell you to put money in gold. At the end of the day if you have no productive use for the asset, why hold it?
I like the Elm architecture so much we have tried to do something similar in Swift on iOS. It’s a shame it’s not possible to go all the way in (it’s quite hard to find an analogy for the DOM diffing view part), but after a year of work or so it looks like the principled state management + message-based state changes + principled side effect modelling brought us about 70–80 % of the advantages. It feels _so_ good so see the state of the app change using well-defined messages and not by ad-hoc state changes on some entangled forest of singletons. I look forward to experimenting with the architecture further. I can’t recommend it enough.
I've not seen/used udptunnel before. Nice. Thanks for the pointer. It looks much simpler than other tricks I've tried to accomplish the same goal.
Thanks for great insight.

Am I right in thinking Metagol requires all training examples to be flawless? LSTM presumably can handle some degree of erroneous training examples.

The ideal learning system would combine these properties: sample efficiency more like Metagol but also some degree of tolerance to errors in training data like deep learning.
While not something to read, I really enjoy GDC classic game postmortems. One of my favourites is Populous. [1] I find it fascinating how such a successful game came out of experimentation without a real plan ahead of time.

> Bootstrapping identity is a very hard problem

Oh come on. Bootstrapping <anything> is hard. Identity isn't special. When bootstrapping, you base initial migration work off of existing systems, until you reach critical mass and the adaptation on top of existing systems are no longer relevant or necessary. You might as well argue that passports are worthless because it's not that theoretically difficult to fake the foundations of identity to a good enough level in order to get a genuine passport. As long as passports are unique-enough (no two people are identified by the same passport), they're good enough. And so is any other system which succeeds at consistently identifying the same person.
There are tons of bugs in 0.18 compiler and 0.18 libraries that will never be fixed. Many of those have / had pull requests by the community members open for more than a year but they were never merged. These are tiny fixes, not 200 lines of code adding a new feature. There's no way to fork a package and apply a patch in 0.19 if the package contains native code. All you can do is report the bug and hope Evan fixes it before your deadline (which ranges from 1 week to 3 years).

Edit: Using a throwaway so I don't get banned from Elm Discourse and /r/elm. I still have production applications using Elm.
I really enjoyed seeing the list, Josh, and I appreciate the share via Twitter and here. My guess is that there are several serial entrepreneurs on Hacker News, and like myself, definitely can identify with your efforts.
I agree. As someone who visits HN practically every day, I had never seen this before, and the book seems very interesting. The chapters seem hefty enough to warrant a post as they come out. Also, it's not one person that keeps reposting, but different people posting.
Articles like this are always half delusional. Yeah you need to be able to fail but you also need a lot of money to continue failing at these stupid ideas until one works. Start ups are toys for rich Wall Street people and trust fund kids. Most people wanting to break in as an entrepreneur and start a business realistically have 1 shot.
Yeah it is definitely complicated. I think there is some degree of travel that makes sense but right now it has become a competition and a game rather than a stop and breathe, soak this in sort of thing. In that sense all this competition is for naught and much more can be learned by appreciating earth where one dwells now. Learn to see and understand the people around you in different parts of the city and better understand ho humanity impacts the environment similarly across the planet.

You'll find plenty of examples of people on DIY or lone-inventor projects saying "we tried X, it didn't work, so we did Y instead. That's the unity-actor case of your hypothetical.

Dividing executive-agent roles is a complexity dimension.

Dividing executive (decision), design, expert (engineering), sourcing, external approval, interface, and labour/crafstmaan roles are multiple additional complexitty dimensions. And this doesn't even include the technical dimensions of the project and its infrastructure interfaces / interconnects.

Complexity is interaction between components and entities.
Personally I would look at the following combination of three metrics:

- Last commit date

- Gross Product Pull Requests

- Number of regular contributors who have contributed in the last six months or so

Then on top of that I would look at the structure and organization of the project and the quality of the documentation. Well presented docs, even if short, and a well maintained release methodology go a long way for me.

I picked up printed copies on Amazon regardless, both because I wanted to support the author after reading almost a full book online, and because I sometimes prefer reading a physical textbook (the "spatiality" somehow helps me remember better).

I'm a Software Engineer without any background in signal processing (or audio), and stumbled upon his books when an FPGA hobby project of mine involved a simple audio pipeline for which I wanted to do some sample rate conversion. Since then DSP has become a hobby on its own.

I actually read the "Digital Filters" book (the second in the series) first, before reading the first book about DFT fundamentals, and it worked pretty well.
