I was rather impressed that someone managed to implement HTTPS on a Zilog Z80. Was less impressed when I learned this MirageOS was merely an x86 OS which apparently stole, er, happens to have the same name as [1].

A couple questions:

* The definition of "low-magic" (v. - presumably - "high-magic") seems to be unclear, even with the rules specified in the "Low-Magic Perl Commandments". It's also unclear if that's a hard restriction on what Perl code RPerl is able to understand or if it's a strong recommendation for performance/safety/security/cleanliness/sanity/etc. Are there any code samples floating around re: what a sample RPerl-friendly Perl program would look like?

* The FAQ states that RPerl is released under the same terms as Perl 5.22.0, which is subject to the GPL and the Artistic License. However, the FAQ states that selling binaries without accompanying source code is forbidden, yet doing so seems to be allowed by Section 4 of the Artistic License (particularly clauses 'a' and 'c'). Is this intentional? Did the RPerl folks mean for RPerl to be GPL-only? Am I just misinterpreting the text of the Artistic License?
It's not clear from that quote if the analyst is referencing the market decline or the freezing of funds in over a thousand stocks and/or actions taken by the government to attempt to control the market.
You already have Yahoo message boards. And it's crappy, but I suspect it's at least 50 percent not Yahoo's fault.

I am normally a pretty level dude, but in this case I really do believe we are dealing with something supernaturally evil. This isn't snooping on randoms, it's exposing demons for what they are. (Atheist, but science just doesn't have the words for this.)
Sadly this is where the UK government seems to be going [1]. They want all encryption to have a backdoor or be outlawed.

Probably condemning myself to eternal down-voting here, but some of the reactions here are depressing as fuck.

There is no world in which this content is acceptable. The presence of this on TOR is not "good for society" in any way shape or form, and reveals that society can't be trusted with anonymous speech...

Which is a really big problem, because there are a shit-ton of other problems that require anonymous speech.

I haven't needed that yet (not at the scale I am using), but that is exactly the use-case I am looking forward to.

I have a lot of interest in seeing our current devops tooling converging with AI/MI. I don't see that happening without something like Docker.
I'm not sure I understand correctly what you mean, but you can either block or send to immediate voicemail individual numbers if you use Google Voice for your phone number.
No, some of us do grow up. We learn integrity and responsibility. We develop greater perspective. We grow more comfortable with ourselves and with the choices we make.

Parents (a.k.a. grown-ups) should not just be larger/heavier/grayer kids.
There is a world of difference between desiring, watching, touching and actual penetration.

We might find the people watching child porn disgusting but they are after all only watching and not necessarily doing anything resembling rape porn.
> The war on drugs didn't work out as intended. The war on pedophilia seems much safer.

We don't have a war on pedophilia. We have a war on "child pornography". I put "child pornography" in scare quotes because it's abundantly clear that many of the laws that aim to target child pornography really only use it as a bogeyman to obscure some other agenda.

Also, as for "safer", whatever we're doing now is clearly putting children at risk. In many countries (including the US), pedophilia is exempt from typical confidentiality laws regarding mental illnesses[0]. This makes pedophiles less likely to seek professional help, and I can only imagine that this means that they are more likely to harm or abuse a child.

Arm vendors lately have arduino form factor dev kits for around $15-30 with onboard jtag. I don't notice better performance using a jlink over an onboard debugger. I've never tried but it looks like you could use the onboard debuggers on your own pcbs and skip the $500 debugger.
Except that the approach the author used is in my opinion completely flawed.

The author states he started from 1 (one) seed URL, and then crawled the sites, visiting links. But that's not valid, as you'd only ever come across a possible fraction of what exists.

To be able to make any authoritative claim, he would need to scan the entire IP-space, like an actual search engine would.

I'm not condoning pedophelia or anything like it, but I think it's naive to take a simple approach and then make authoritative claims about the entirety of the TOR network.

But I also think that there were flagrant abuses that could be pursued under the CFAA. Just because something isn't "per se" malware doesn't mean it wouldn't fit the legal definition.
I don't find it that odd, but what I do find odd is that in these days of smartphones the software dialers don't make it trivially easy to block incoming calls. You have to choose an app if you want to block calls and most people are understandably a bit hesitant to replace the default app that came with the phone with some third-party one of unknown provenance. This is a pity, because if users could easily share telemarketing blocklists and so on you could shut down abusive calling industries very very easily.
I don't think it'll rebound tomorrow, but it will eventually (next week?). The fundamentals are all the same, the valuations just got too high. Right now its just panic selling. Most of the stocks I'm following are still higher than I bought them for initially.
Delay filters are built intentionally by RF engineers for pre-distortion and probably other purposes. I think the limit for such simple designs is ~100 ns.
"...I'll be buying at the bottom."

When I went to casinos for fun I never heard anyone admit they lost money gambling. This statement reminds me of gamblers who never admit they lost. You can't predict the bottom. It is highly unlikely that you will actually buy at the bottom. You were speaking hyperbolically I know but the sentiment is a bad one to have when it comes to investing and gambling.
This is the best argument against "personal responsibility" ever. I don't want to protect myself from Comcast bothering me, I want them to observe courtesy. We have laws for that.
Thanks for sharing. I remember the pictures of intermodal containers for explaining this.

Sadly, I also see writeups that focus too much on the virtualization aspect. The journalists are searching for something to compare it to, so Docker gets compared to other virtualization and resource isolation tools.

Growing pains, I suppose?
You're right, I did misread the note -- see updated version. Interestingly, Alibaba's IPO came at a time of accelerating revenue momentum.
Ask HN: How to earn $200k salary or more?
I am on cell phone so apology in advance for short sentences.

I have 8.5 yrs of experience. I am in SF and earn poor man's salary of little over $100k. Rent and commute takes upto 30 % post tax deduction.

I am very well versed with hadoop ecosystem ( pig, hive, python and java ) and do excellent job of data analysis, bringing meaningful insights to forefront, writing complex functions and more. At my current job I am becoming bridge between technical and business side. Unfortunately, growth is very slow and there is too much noise for any recognition.

I would love to do my own startup one day but i can't for reason I can not mention publicly.

I am looking to break into management but so far I have not been successful. At current job it's tough to become manager due to internal politics.

Any suggestions on how can I land a job that pays $200k or more ? I am looking at total compensation of $200k although not big chunk in imaginary equity. If you earn $200k or more, what do you do? How did you reach to that level ?

I have degree in engineering and hold number of certifications with recent one from Stanford.

Nobody is pretending that receiving money from Peter Thiel makes you better at whatever it is you do.

But a lot of people, such as Harvard admissions, do pretend that attending Harvard has such benefits.

In contrast, no one at Harvard is pretending that they couldn't afford to enroll ten times as many students.

Put another way, Thiel fundamentally doesn't fund most people because most people are bad investments. Harvard admissions isn't claiming that it won't admit you because you're a bad investment and would devalue their brand. They're claiming that, if you were admitted, the experience of attending Harvard would increase your personal quality, but they nevertheless won't admit you for undisclosed reasons.
You will get quite a different punishment for watching child porn than from raping a kid. So yes there is "just watching" That doesn't make it less disgusting but it's not the same.
Pretty amazing work to put this all together in perl! My only worry is commandment #45 as a lot of the perl I've seen is mostly regular expressions.

A a fellow atheist, I agree that evil is a real thing, but I still don't see the need to call it "supernatural".

Evil is the opposite of good, so if we agree that actions to promote life, liberty and happiness are good, then actions that promote death, slavery and misery are evil. Simple as that.

So there's plenty of evil in nature.
Yes, the West is still dominant but geopolitical and economic power is shifting South and East and Western influence and power is waning. China and the U.S. both know that at the moment each nation is dependent on the other and the collapse of one would have serious repercussions for the global economy.

Hence we get scenarios where China is claiming islands a thousand miles off its coast as domestic territory and while the US Air Force flies overhead and Obama tut-tuts the whole thing is a boundary pushing exercise (no pun intended) and China continues to do what it wants, within reason. China knows that shooting civilians as in Tiananmen Square in 1989 makes for very unflattering optics and jeopardizes the Western trade and investment it needs.

Every day articles and blog posts announces the imminent demise of US and Western power or China's impending economic collapse. It's possible of course but for the moment not very probable. But it is clear that the West is no longer *utterly dominant.
but, this is different.

The game isn't to find something exactly analogous to something else in order to expose the flaw in the structure of someones thinking. Example: take a gospel, replace every instance of the word God with Mickey Mouse. Is Mickey Mouse analogous to God? No, but the trick helps us analyze the original text in a more objective way.

My conclusion don't try to legislate against every dick move - teach people to be more thoughtful of others was an objective response to more laws governing what people can do in their own homes. Now let's explore it further because the concept of banning smoking in someone's home is fundamentally flawed:

How do you enforce such a law? Can someone just barge into your home, slap the cigarette out of your hand and give you a fine or take your children away? Could it be abused much the same way neighbors might falsely report you for neglecting a child because they have a beef with you? How much do you fine a person if the purpose of the law is to protect the children when fining the parents will leave the children with fewer resources? Do you give the parent a criminal record? Will that help the children more? What evidence is required before barging into someones home? Do you even barge into someones home or do you politely ask them at the font door "Have you been smoking in front of your children?"
I'm pretty sure science has the words for it. Also, supernatural things, by definition, do not exist. Pedophiles unfortunately do exist.
Yes. I was not clear: My

If it was a claim my friend I would not have posted it via hacker news. I have posted it to bring awareness. The proof I have is I do not use my personal computer at work (luckily had backed up emails on personal laptop) which is from 9am - 6pm. Also I checked my gmail today at around 1pm and only read a conversation in which did not include airbnb. Lastly, why would I delete an email if I am disputing charges against airbnb?
Well, at least two thirds. More like 4/3 in various combinations and configurations.

When I first heard of contributor I got excited that Google might be pivoting their revenue flow. Recognizing that ad revenue days may be numbered due to the increasing popularity of ad blockers, I figured Google was turning into an automatic version of flattr. Unfortunately I've heard contributor works by out-bidding all the other ads on the site so, assuming that's true, I'd say this is just an attempt to increase bidding competition to drive up ad prices.
If watching a crime is a criminal offence, you better lock up the viewers of CNN, Fox News, and the BBC.

I do think their ought to be laws against the distribution of this kind of material (there probably are?), and there is no question that producing it is a criminal offence, and should be prosecuted to the fullest extent of the law.

I always wondered what evidence there is that a trading freeze would stabilize a market.

Considering the US market has trading halts as well, US regulators should take note: Sometimes a stock goes down because it should.
No, it's because a house is 400,000 times more valuable than a can of coke.
It's a shame you chose to dismiss the discussion rather than concede the point.

I mentioned that Gavin McInnes is a person who has made a living spewing incendiary, bigoted hate speech. You argued that we should still listen to him in order to not violate the ideal of freedom of speech. Other people eloquently pointed out that this is wrong, both by any reasonable moral standard and by the traditional motivating principles behind freedom of speech. You called those people trolls. That's a shame.

800,000 people in the US are now on the sex offenders registry [1]. I think it has become clear to at least half the nation that the laws have gone too far on things like teen sexting or getting put on the registry for public urination.

A friend of mine, her boyfriend is a trucker. He had pulled over to urinate along the side of the highway late at night, in the shadow cover of his truck. A state trooper had pulled over a speeding vehicle, a distance behind him along the road. The trooper proceeded to then pull in behind the trucker, and threatened to put him on the sex offender's registry for public urination; the trooper spent 10 minutes reaming him out for it before letting him go.

i like how the plan9 system calls list can fit on an index card.

I guess that i'm then wondering, to what extent are the profusion of api calls on bsd/linux (by comparison) due to which of the following: a) legacy of evolving richer apis while supporting older ones b) poorer factoring of abstractions c) different special casing for various performance or security related primitives?
So you want to collect enough taxes to have the government provide zero interest mortgages. Does that mean everyone gets a mortgage, regardless of creditworthiness? You want me to pay for other people's mortgages, when they won't even give me one?
That you can read the law such that your hypothetical Go Pro wearer is guilty of those things, doesn't mean that prosecutors would ever bring such a case. Laws are drawn more broadly than they're enforced, and even an overzealous prosecutor has to get through a judge and jury.

Downvoting a post because you don't agree with the argument is silly. I wonder how many downvoters think they are pro-free speech even as they demonstrate their hypocrisy.
This is a very important/interesting question,i wish more people would give they thoughts on it.

I don't think you are approaching the question from the right angle. If by 'interesting' , you mean problems whose solutions would provide a lot of value (whether you want to convert that value into money for yourself, or just looking for the satisfaction of doing some good in the world), then most of those problems are just not problems yet. Nobody has actually identified them as such.If you think of it, before google map,facebook,Uber,wikipedia etc... nobody actually knew that we needed those. The problems were there, just that nobody though of them as problems or nobody could anticipate the magnitude of the value that solving those problem would provide.

I think the guys from Y combinator (or is it from the book zero to one) say it perfectly : 'Which company nobody is building...'.Nobody is building them not because of the lack of resources, but because nobody have found a way to identify them. So to answer your first question, nobody knows how to reliably and repeatedly identify interresting problems.

As you i have been think about this question quite a bit lattly, here my though so far :

1 - The difficulty of identifying worthwhile problems can be though as a form of uncertainty, so learn about strategies to deal with uncertain environment. Zero to one, lean start-up and anti-fragility all treat this subject from different angles : in a nutshell, forget about find the right problem, start multiple small projects, iterate fast, be flexible, invest small and kill then unsuccessful project quietly.

2 - The other strategy is to leverage your particular expertise to identify problem in your domain. Depending on your domain, you might stumble into a niche problem which can generate a a lot of value for yourself (since you would have less competition)

Hope it helps

Behavioral economic studies show that humans prefer to avoid loss more than to gain --

So it's possible that markets rationally cut losses more than they rationally add capital to undervalued stocks.

Regardless, all the "freeze" does is make the published "price" no longer reflect the market price.
Here's a long vid of Kay showing off the fruits of STEPS and doing his job to remind us that because we forgot about the work done in the 50s-70s, we've spent the last 40 years rediscovering it and are only recently starting to catch back up.

https://vimeo.com/82301919

It's important to note that he is giving his presentation using STEPS' custom productivity suite; running on STEPS' custom OS; both of which were compiled using STEPS' custom languages and custom compilers all the way down to the assemblers. And, the whole package (OS, compilers and all) totals well under 100K lines of code with no external, non-STEPs code introduced.

It goes hand in hand with the fact that there's no reliable system for identifying the origin of an incoming call. Telcos won't let Caller ID information be reliable enough to be used for blocking purposes, so there's clearly a lot of money in aiding and abetting the telemarketers/scammers.
Not advocating but I think you can invest in ETFs that track indexes like MCHI and ASHR.

I think it is OK to have trading halts for particular situations. For example, a stock may be going down quickly just because of a wild rumor. Halting trade for the day may give time to investors, so they can consider what the facts are before taking a more informed decision. On the other hand, I agree with you that trade freezes are not enough to fix true underlying issues -- as it seems to be the case with China.
