One of my goals for the next few years in my life is building a proper personal knowledge system, combined with everything that is needed for something like that to work. Mostly online, but there might be access from desktop/mobile apps. Included system like Anki. Wiki-like website for everyone with good tagging/linking between each posts. You can then make each piece of content accessible for everyone, behind a password or just accessible for you. Additional features like daily journal, todos, short/long range goals, asking you for permission to open all your content to the public if something happens to you/or you decide to not pay(small monthly charge for hosting and maintenance), of course if you want you are free to not allow that.

I feel a lot of people on HN have great and organized knowledge system and open sourcing the system with the knowledge/the knowledge part is important/ would be great. Of course it will take some time and effort, but I would love to have access to such system of some users like patio11 for example and gladly will pay money for something like that.

P.S Feel free to copy the idea, I am pretty sure that it is not unique anyways, though I am not aware of something that has done a good job in this area. Think of it like an open source knowledge system with a hosted version.
I think they will, is just that their devices will not be sold for making profit, but for messaging and authentication.
Perhaps I was unclear, and if that's the reason for any confusion I am sorry. I was referring to the majority of the comment which was about portage's shortcomings (though it is also true that ebuild quality is a major problem for gentoo). I specifically was comparing portage/the Gentoo package management infrastructure (NOT the package repos per se) with Exherbo's package management infrastructure (by which I mean the package manager, alternatives handling, repositories). This is what I meant by "Exherbo's package management"; that does not mean the breadth of the repositories.

I like to think my comments were honest: I admitted that the system while technically superior does not have the breadth that larger distributions do, but that for my purposes it was sufficient. You ignored that and found some packages not currently packaged in an attempt to disprove my experiences. Furthermore I admitted that the project may not be for you since you expect different things from a distribution than many of us do. What is dishonest about any of this? I have been incredibly frank.

Besides, one of the nice things about Exherbo is that it handles the nonexistence of a package rather seamlessly. You can compile it by hand, install to a tempdir, and then have the package manager merge it directly while giving you the ability to specify information about the package (metadata, dependencies, etc.). And then of course the package manager can uninstall it when you no longer want it. This makes the problem of "build it yourself" kinda moot.

I'm not going to bother responding to the "make the cut for a live CD" remark since obviously the there are far more packages than would fit on a liveCD or liveDVD.
"A specific challenge designing the vehicles was achieving
esthetic qualities as well as functionality. Our vehicles had

This is an understatement. I was impressed.
The "outsourcing" of the boss fight is just that they asked the people who made their AI middleware to program the boss fights because they were rushing to release the game. (Source: I know someone who worked for the very small company that made the AI middleware) That's also why so many areas are so small and why the boss characters aren't properly introduced.
To me, it only hints at that (a problem that I agree is substantial). The main issue is that our legal system is simply not very well-equiped to deal with issues that require true expertise from a professional outside of those with law degrees.
It's an adult approach to work. Like linkedin / Reid Hoffman's approach to career development: stop pretending you're joining a company for life; instead, treat employment as a tour of duty with limited duration. The company gets X from you, and you get Y from the company. At the end, you may or may not choose to re-up, with new goals for both sides.

ala https://hbr.org/2013/06/tours-of-duty-the-new-employer-emplo...
Eh... sometimes? But, honestly, that's not an assumption that should be made... you need to be fluid enough to handle it all. Even in the Theoretically Standardized codebases, different approaches and styles come and go according to the fad du jour.

Right now I have to deal with 3 codebases on a regular basis, in three-four languages, written partially by people not even here, over the past 5 years. On a bad week, I have to crack open 3-4 more codebases in 2-3 more languages... and don't even get me started on reading open source code.

If I am looking for predictability, I'm going to be disappointed, and if I need it, I'm going to fail. Grok it is what I say.

That's clearly not my ideal.

I can see how we first-worlders really like net neutrality and everything. I do see that we fear that our web access might get more expensive if access prioritisation is successful somewere else, but: Since we all already do have access to the internet it just appears to me to be endlessly selfish from us to make them wait 10 years to get the full internet for themselves.
> We can restrict modes of expression without restricting content.

Absolutely we can, but we need to be careful in how we do so and we really should be limiting those restrictions to the smallest number possible.

Niceties like "freedom of speech is not freedom from consequences" help us easily accept more restrictions on speech - in fact they make those restrictions seem like common sense! As a society, though, we should be ultra-vigilant when it comes to protecting our speech and only restrict it when we are absolutely sure it is necessary. I'm not just talking about legal restrictions here, either, cultural restrictions are just as important. We don't want to find ourselves in a situation where the "mode of expression" being restricted is, say, talking to friends in a bar.
And I thought the local cinema here in Kyoto was crazy for only allowing paying members to buy a movie ticket more than 2 days in advance!
The author states in the article he's more interested in expanding the use of the blockchain as a ledger (as opposed to a store of value).
Been using it for almost two years I guess. Find it really nice. Would one day love to be more able to script with it; adding more features for my own needs.

Give it a try at least :-)
This makes no sense. This is what a current Bitcoin mining operation looks like.[1] It looks like a low end data center. Few cables, because the miners only need to communicate when they find a block or are getting new starting points. Power and cooling costs are a huge issue in Bitcoin mining. Most profitable Bitcoin mines are in cold places. This one is in Sweden. There are bigger ones in China. There's no way a small, low-powered Bitcoin miner can make money today. That era ended years ago.

The way Bitcoin mining works, you don't get anything unless you win an entire block. That happens about once every 10 minutes over the whole Bitcoin ecosystem. If they're talking about "a constant stream of satoshis", they mean you're a slave of their mining farm, working for them and maybe getting paid some pittance by them.

Is this thing a hoax? They're on Reddit, Twitter, and Medium. They have a web site with no useful information. (https://21.co/) They claim to have a development kit, but have no pictures or specifications. There are no numbers about this, just PR blithering. It looks like another Bitcoin-related scam. It's been only few months since the last big one, Paycoin.[2]

> Towards that end, our team of PhDs in EE from MIT, Stanford, and CMU has built not just a chip, but a full technology stack around the chip — including reference devices, datasheets, a cloud backend, and software protocols.

This is pure marketing fluff. They should be embarassed by this.

Plus, there are tons and tons of capable PhDs and non-PhDs from lots of other schools.

Moreover, as others are saying, it doesn't make sense to waste electricity to mine bitcoins in small quantities.

edit: Given that it doesn't make sense, does anybody know what they are really doing?
I am extremely glad that most comments here see the inherent craziness of this idea. I am a hardware designer who participated heavily in mining since Jan 2011, and gave up completely on Bitcoin in summer of 2014.

The big problem that Balaji is completely ignoring is that SHA256 cores implemented in silicon have extraordinarily high power consumption relative to their size (mm2). This is due to the incredibly high signal switch rate inherent to implementing avalanche-style ciphers [1] in hardware. Perversely, most modern semiconductor processes optimize for static (leakage) power, since modern silicon designs are more vulnerable to this than to dynamic power. No rational semiconductor maker will want to include this IP on chip, because it will drastically complicate the power distribution metal layers. Additionally, it will require more expensive packaging, since you will need many more power and ground pins to source/sink the required current. I know this first hand after building a mining ASIC myself. I would venture a guess that most SoC chips would cost significantly more due to the extra engineering time and packaging cost needed to include this IP.

This entire concept is a non-starter for me.

This doesn't surprise me at all. It is trivial to run a site on app engine that can handle hundreds of requests a second continuously without leaving the free tier.

Sure, when the change from billing CPU time to instance hours came in some app's bills sky-rocketed. But that was because they were poorly coded such that instances were blocking and unable to serve incoming requests.

With a thread safe application and the proper configuration there is absolutely no reason why instance-hours pricing shouldn't be competitive.

QA = Time and Money. How much should you invest?
The autosuggestions looked pretty sweet! Here's something that enables similar functionality in zsh: https://github.com/tarruda/zsh-autosuggestions
The shell is completely independent of the terminal emulator. Fish is the former, while you're complaining about an example of the latter. (My recommendation for a terminal emulator would be urxvt with the tabbedex extension. YMMV.)
I can't believe they actually believe in the 'device that pays for itself' type of scenarios. Are they that stupid or outright lying?
I am sincerely curious as to how music could be not qualitative (IE, quantitative). Is better music just more notes? Or more words? What numeric value of music would be better? Making more money, perhaps?

Or are you saying that a music's popularity, in terms of how many people listen to it, is how you determine it's value?

That is definitely an interesting way of looking at it. I can't say it's not a valid way of measuring it.
I was just thinking about how no one even pretends GNOME Shell is a serious contender any more. Sad that they've squandered their installed base so thoroughly.
I by no means would call myself an expert on Bitcoin, but I did coauthor a book about Bitcoin.

All I do when reading stories about 21 Inc is parse every sentence very slowly saying to myself "What is it I'm missing that turns this from a terrible idea into a good one?"

I have yet to discover such a sentence... I hope I'm wrong and will still read it at some point.
Fish is great. I've been using it for close to 3 months now, was using zsh with prezto before.

I find Fish to be simpler to use and more powerful by default. You can probably have a zsh or maybe even bash setup which does the same fish does, but I don't want to do that.
I think he's referring to the rumors that they're involved in low budget blue movies as well.
> Its a complete misallocation of resources.

Where have the resources (people) been over-allocated to?
I don't believe there are any ESP8266 modules with FCC modular certification yet.

I prototyped a CC3200 module but stopped working on it when it became apparent that the ESP8266 was here to stay. It's a simpler chip with fewer available GPIO pins and less processing power, but it can be packed into a much smaller area than the CC3200 (CC3200s require 3 separate power inductors!).

It's important to note that the ESP8266 may well be more open than the CC3200! Much of the CC3200's functionality is packed into a binary blob from TI, and the chip runs this code on a second core that you don't have any control over.
make it like a mail in rebate, I bet something like half of those never get sent in so people who got the 'paid' version but don't claim the coins after X days have them sent off to the company anyway.
I really find the phrase "embarrassingly parallel" obnoxious; nice to find out (on the Wiki link) that I'm not alone.
Very interesting read. Would be really cool read a similar article about what is going on in a bleeding edge AAA engine these days.

> CEOs appoint the committees that decide how much they’re worth

Correct me if I'm wrong, but this isn't true unless the CEO has significant voting power as a shareholder. Right?
Cyc started in the mid-80s when rule-based AI systems were the norm. Everything in AI looked like a theorem prover back then. However, in the 90s, statistical methods began to produce better results as techniques were refined and computing power increased. What's better: a system that produces the correct (or good) results 85% of the time, or one that produces no result until the database has a necessary rule added? Industry prefers the former (although there are definitely uses for the latter).

Its connection to AI still remains, but the field has largely moved away from the rule-based paradigm Cyc is based on. I mean, you can throw a whole wikipedia segment into Doc2vec (a lightly supervised deep-learning technique) and it can discover non-trivial links between semantic objects with a few days work. If you tried that with Cyc, it would take longer.
I am so torn between wanting to cheer anything Sandstorm-related and thinking that your Sandstorm hosting provider should also set up the DNS for you.
What do you mean "scripted" ?

Almost no combat game has true IA.
It's extra funny because without stiching together stack traces you lose the stack by using A+ Promises.
I think what the author is getting at here is that CEO pay was in an unstable equilibrium, and that starting in the mid-90's, that balance was tipped, causing "run-away" CEO pay.

I don't particularly agree with this conclusion, but the "unstable equilibrium" hypothesis is what is implied. "The conditions were always there, but some instigator (MNF) triggered the change."

I personally think adventured's hypothesis regarding stock market performance has a bit more merit.
How do you get people to invest in such an idea and write such excited statements? Almost nothing they say makes sense. Mining on battery powered devices. Abusing the block chain as a database. Making other people pay for you.
The Psychology Behind Branding
Thanks for the feedback. Part of why I say that I'll be a junior for a while is that I need to pick up a lot of best practices and general intuition on projects. Learning alone sort of blocked me off from that experience early on. Just gotta put in the time.
This seems like it's for people setting up their own sandstorm instances.
Wow this is actually really cool. Like if I had to work in Excel regularly I'd use this in a heartbeat.
How to Survive an Earthquake
Those ceilings. I don’t think I’ve seen any work of visual fiction – game, movie, or otherwise – in the past decade whose art direction felt as genuinely futuristic as Human Revolution did. From amplifying current trends (extrapolating Zaha Hadid into wild, web-covered high-rises) to speculating the black-swans of fashion (a sudden rise of neo-Italian Renaissance couture), mixing in streaks of classic cyberpunk (Hengsha’s city-over-a-city), the game’s aesthetic is immersive in a way not even matched by even its (in some ways superior) predecessor.

The internet joke about the original Deus Ex is that every time it’s mentioned, someone reinstalls it, but I think this just convinced me it’s time to replay Human Revolution.
Which is strange given their cost-savings examples using bitcoin mining.

This might work for authentication, but they shouldn't sell it as "bitcoin-subsidizing devices for the developing world".
> It doesn't make sense to use pure supply and demand for land at the very bottom level of human sized parcels

I don't think you even have to go this deep.

The banks are the ones that create new money, multiplying deposits tenfold based on the valuation of the assets they're writing notes on. But that valuation is set entirely by the selling prices!

So in this circular situation, the only downward pressure on housing is what the banks will loan (especially with further down-payment-erosion like PMI), which is set by the carrying cost of the capital (interest) times what people are willing to pay per month. There is no risk of default since on paper, the asset is worth slightly more than the loan.

I think if you were to revoke financial primacy and eg disallow repossession of residences in bankruptcy, you'd see a pretty quick correction as there would then be an actual risk that someone would take a loan to buy a house and then decide servicing that debt was pointless.

But there's no political capital, since everyone that has bought property (even and especially with a mortgage) wants to see the bubble keep going up forever.
Cat righting reflex
No, the decision was based entirely on his age (and standard department policy); the coroner was not subtle about it. He died at home.
The ESP8266 has an Xtensa processor (IP from Cadence, originally Tensilica). As far as I'm aware, all Espressif wifi ICs use this core.
Question from someone not knowing much about low-level programming and dealing with signals:

If signals are so problematic, why rely on them? Is the functionality useful for other things other than dealing with 'emergencies'?

One thing I can see that is useful, is that it allows a program to gracefully deal with a kill, but many applications seem to have a 'graceful stop' mechanism that doesn't need signals.
Meh, nothing that would make the newspapers, not even good enough remembering details about 10 years later - sorry to get your hopes up :) Internal company meeting notes, reports on legal proceedings, I remember some correspondence on a divorce, checklists and procedures for business processes, test grades and student notes from schools, that sort of stuff. Excel sheets with budgets and timekeeping sheets, just typical office stuff - no .mil or at least nothing interesting, I would have remembered if it had been anything juicy. Maybe Google results didn't show those, don't know.

It's not rocket science - go to Google.com, type "[some keyword] filetype:doc" (or pds, or xls, whatever), skip to page 10 or so, then start looking. I had to click just twice before I found (5 minutes ago) meeting minutes from some British council meeting, marked 'confidential and not for distribution', complete with names and dates/times. Go to your 'private files' folder on your machine (you know, where you store your job applications, that invitation you made once for your sister's birthday party, that sort of junk), look at the documents you'd least want somebody else to see, identify some keywords that are in those documents but not usually in others, use those as keywords in Google.

Here's a fun one: "site:gallery.mailchimp.com filetype:pdf coupon". Nothing shocking, but I still don't think Mailchimp's customers expect their email list attachments to show up like this... (disclaimer: pure speculation, maybe these are meant to be publicly available, or maybe they're not even real customers and just test data, I read it for the articles, etc.)
Some of us are hyper-capable at making educated guesses about people's intentions and even ulterior motives; where we suck is in generating appropriate responses.

These comments remind me of the crapping-on uBeam took on HN after a few people decided, upon a cursory glance, that it was theoretically impossible and ridiculous.

https://news.ycombinator.com/item?id=8542091

We still can't be 100% sure if it's ridiculous or not, but all signs are pointing to not. So assuming Balaji et al are acting in good faith and aren't scamming their investors (one of whom Balaji is a partner in so that would be weird) this is cool and I can't wait to see what it does and where it goes.
That's what I was thinking. I've been pretty into cryptocurrency for a good while now, out on some pretty distant frontiers at times. And the mining aspect of this makes no sense at all to me. I don't get it.
Ask HN: Best practices for securing clustered services
I'm currently setting up a scalable application and was wondering what the best security practices are for a multi-server setup.

Currently I use SSH key authentication on each server - but how do I handle passwords for sudo? Should I disable sudo password checks? Should I use the same password for every server and rotate it every week? How about database passwords? Should I remove the need for a password by SSH tunnelling to the master DB server?

Thanks in advance!
Before the pricing change app engine did not support concurrent requests to a single instance for python. As a result, applications used many more instances than they needed.

When using the calculator this would make the price increase seem enormous to many customers. When concurrent request support was added (it was available to trusted testers at this time) all a user would have to do was add "threadsafe:true" to the app.yaml file to enable it (assuming their code wasn't doing anything silly).
See also https://news.ycombinator.com/item?id=8936701 (back when it was first presented and this happened)

Seems like they were kind of surprised by the fact that people actually looked at their toy as a serious thing. If you just play with something yourself it isn't an issue if you use others' assets/code or not, but as soon as you publish it that doesn't fly anymore, and fixing that didn't happen when they made that step.
If you want an idea of the milieu they're operating in, this might provide some context (the former was published a couple of day before the NYT article).
