I think bitcoin is a fascinating product. I'm not sure what the real world value may be though. Lots of thoughts on what parts of bitcoin might make life better for the masses but we haven't seen it yet. I think we will but for the moment we have to conjure up these things in ways that are immediately made possible by bitcoin.

I think 1) eliminating fees of all sorts (credit card, foreign currency exchange, etc.) 2) anonymity of purchases are just a few examples.

I don't think anything I've heard to date really strikes me as what will make bitcoin (in whole or in part) as successful as I believe it will be.

But this is what startups do. Figure that part out. Bitcoin isn't any different from other disruptive ideas. We will get it wrong many times before we get it right.

I guess what I'm saying is that this is the process of innovation and it often seems boring and wasteful. But have faith in the process!
It was a mostly manual process. I was trying to understand why four rules (one for each output pixel) were needed inside every case statement. So I wrote a parser for the original source file that turned each output pixel rule into an integer representing what the code for it was actually doing.

From here I noticed the strong symmetry when you rotated the pixels. Which of course makes perfect sense, I was just able to confirm it here.

So I tried to reproduce the same tables using a LUT and rotate table, and matched all but two instances. This seemed really weird to me, since I figured this would have to be generated unrolled code, right? So I asked Maxim about it, and he said that they were probably mistakes. I was pretty shocked myself that he did this by hand.

I did a few blind comparison photos on my board to see if anyone could tell the difference (in practice it amounted to one or two pixel differences in each 256x224 upscaled image), and everyone actually favored mine, so I just went ahead and ignored those two differences.

I'm curious if the blog author noticed the same thing, or if he noticed the rotation quicker and only built his tables off of the top-left output rules.

Ultimately it looks like the blog author found a better route to reducing the comparison rules than I did. But I still don't think we've 100% cracked how and why the original author chose the rules he did. And since it sounds like it was done almost by sight, we probably never will.

Still, I'd really like to see if someone could find a way to generate the comparison rules mathematically. It's very likely that if we had some sort of scientific basis for when and why to blend each case, we could improve the visual appearance beyond that of the original algorithm. Obviously perfection doesn't exist. I'd expect the end result to be a function that takes tuning variables, and different input images would look better with different tuning values. But even for the default case, I bet we could do better.
Makes a hell of a lot more sense than rebasing 70-odd separate patches for your internal use! Making LibReSSL-portable is a good goal, and this work can be used to improve both (and OpenSSL, too - some of this found its way into the OpenSSL 1.2 branch).

I think the "safe" (EC)DSA nonce implementation is interesting but could use some review, and I've communicated that to the author: it's not as good as the proposal in RFC6979[1] (which uses HMAC_DRBG - which is good - to generate a truly deterministic DSA nonce, with test vectors and everything!). In particular, BN_generate_dsa_nonce from these patches uses modular reduction down into the prime order, which has a small bias towards 0 of course. The NIST prime orders aren't as close to powers of two as you might like to get away with that, and if I'm being honest, I'm not sure you can get away with anything with (EC)DSA - it is extraordinarily fragile in a way I think was always deliberate. The practical impact is probably limited, but I really don't want to take any chances there. (Ideally I'd want Ed25519, or something very like it - there really ought to be some more discussion on CFRG about that - although it's going to be quite some time before anyone can roll it out in certificates widely.)

Right now, it's still lipstick on a pig. OpenSSL is hairy as fuck. Long-term, I think the LibReSSL cleanup-via-demolition approach and then carefully rebuilding what's left over is what's needed. But I'm not sure I'd want to run LibReSSL in the middle of such fundamental reworking - and in the meantime, some of these patches look quite familiar to me. :)

No, you've oversimplified again. Many whole-home Airbnb rentals --- most, if the narrative of the site is to believed --- are owner-occupied. They don't have the inventory risk problem. A hotel is an investment that must make some minimum return, or else go out of business.

I found the addendum about the time-sequence of bad acts to be the most interesting, in that how you approach the problem leads to another wide spray of outcomes.

Scott mentions the "forget the past" and "address root causes" sides, but how do you deal with things in the middle?

Even being able to provide a model that allows for injustices from centuries ago would be impressive, but how should such things decay? Again, the same pressures come into play, based on the interests of the judged parties.

Wow that's interesting I haven't seen that yet.
This is an interesting idea. Aaronson may be joking when he says he's "solv[ed] a 2400-year-old open problem in philosophy," but in case he's not, this doesn't come anywhere close to solving ethics. Philosophically speaking, it's still necessary to show why his definition of "moral" holds up. All he's done is assess a certain quality and then call it "morality." I think it could better be called "meta-cooperativeness" or something like that.

I think Aaronson realizes this, because he does talk about how Eigenjesus and Eigenmoses don't accord with our moral intuitions in some cases. He also addresses this somewhat in the section "Scooped by Plato." His major point--that something like Eigenjesus can be useful, even if it cannot deduce terminal values--still holds.
I don't understand your first point sorry.

About the second: A few remote developers in low-cost countries can pull off EU/US like rates. But these are exceptional guys who typically have worked on-location as a contractor in ex. London or Berlin for a couple of years, and have proven themselves to specific clients.

That is a very uncommon situation though. The reason offshore developers can't charge the same as their EU/US counterparts, is not ignorance or desperation. Rather, the majority of companies' have no reason to hire a guy in Ukraine versus the guy around the corner, if the price is equal.

Again, at least unless the client already know the specific guy in Ukraine. Then it's a whole different ball game.
The aircraft I flew in the '80s had an artificial horizon that showed whether you were straight and level. That aircraft wasn't capable of inverted flight (or maybe I wasn't) but the dial was vertically symmetrical and the only indication you were upside down would have been the (small) printed numbers showing you degrees. I saw the same dial in a flight simulator for an A-10 Warthog, so I'm assuming there were cues but no flashing red light.

For some reason I was not expecting HN adults to be surprised/bemused over high school material. My bad, I guess.

Anecdotally, I can corroborate the observation: weather.gov slightly underpredicts rain; a "30% chance" is associated with rain more than half the time.
I guess if someone had experience, or was trained well, they could potentially be selling without coming across as selling. Like you rent from a real estate agent and he's sort of running through the typical questions in a conversational manner...

For instance, I just stayed with someone who manages music events and does promotion for bands. If I needed someone for those services in that area, that's my go-to guy because he came off knowledgeable and friendly.
A good point ... and wings are designed to provide lift while flying right-side-up. While upside down, you lower the elevators to promote level flight.

This seems related to the idea of coherent extrapolated volition (https://intelligence.org/files/CEV.pdf). Both have some of the same problems--in particular, setting up the system requires making moral judgments about how to do so, so it's not actually value-neutral.

(Aside: If I have two completely different thoughts about an article, should I post them in two separate comments or in the same comment?)
I dont really listen to music. But sometimes I like to run an action packed movie in the background. The movie shouldn't be new to me, preferably in other language too. Maybe I like it because of adrenalin rush. :).

Even those rainy moods are better than music.

Music distracts with an urge to sing with it. And with instrumentals I get bored soon.
There's a kind of live by the sword, die by the sword theme here. If government rules can be enacted to make an item's value go up, they can also change to make the same item's value go down.

How exhaustive is your knowledge of the US tax code?

> Are America's poorest better off because of technology, or better off because of America's dominance over the rest of the world's resources?

The rest of the First World seems to be doing OK, even without anything remotely close to the US military. Though I would be surprised if developed countries didn't continually try to suppress underdeveloped nations, maybe not by military force but by market forces etc.

Well, I just assumed it was symmetrical because I couldn't imagine it to be unrolled manually (I just quickly watched the visual representations of each side)... But now that you pointed out this I guess I'm going to check for differences, in all the filters. Do you remember on which side the typo was present?

And yeah, we still haven't really cracked the algorithm. I initially wanted to write the article as "understanding hqx", but I actually realized I still don't really get the rules.

Ask HN: What is the best way to find web development freelance clients?
Everybody here is saying that bidding websites like oDesk and such are bad, and that successful freelancers find clients via their network.
I am only getting started and don't have a network yet - what is the best way for me to find clients? What is the best alternative to bidding websites? Cold emailing? Using SEO to drive traffic to my website(seems very long term)? What are the other options?

"sans two cases which appear to be typos in the original algorithm."

By chance, do you have more details on which two specific cases are 'typos'? It would be fun to try fixing them in the original code and see what kind of change occurs in the output.

At that point, something like Uber still makes sense as a centralized ride brokerage. Cab companies will have driverless cars that go everywhere, but on many cities, no company will have enough cars for you to just want to go to their website to request a ride.

It becomes a mix of Expedia an an auction site. You say where you are, and where you want to go, and get bids from car companies that claim to be able to get to you in X time, and charge you Y to get to your destination. You get to pick. With automated cars, their bids are all by algorithm.

I'd be shocked if the Uber people weren't thinking about this problem today.

As for "is known to have relayed links to Microsoft from chat" I dont even get what it is supposed to imply. Some Microsoft conspiracy to listen to Strong AI chats?
Maybe not. http://techcrunch.com/2013/08/25/uberauto/

I think the general idea behind driverless cars is that they can be JIT-rented, and since Uber would have the infrastructure in place, they would be the natural market leader.

European countries are not directly threatened militarily by the US, but Russia is. Europe is being merely exploited economically.

But even now that the Europeans are fully aware of being spied upon by the US, they can not do anything about it without hurting themselves in the process. Europeans are weaklings, and not willing to endure the smallest amount of pain, even to avoid bigger pain down the road.
Am I the only person that thinks government regulation is a reasonable thing for the taxi industry? Regulations on work hours, car safety, tougher environmental standards, driver training, requiring pickup if called, etc all seem reasonable. It's unfair that Uber is able to skirt most of these rules. The same could be said for hotels (noise, safety regs, etc) and restaurants (food safety, etc). Should all services be unregulated? Anyways, I do think things like Uber and Airbnb are very cool and innovative, I just feel a little uncomfortable about where it's leading us to.
It would be interesting to repeat the comparison for many specific locations, then plot the measured variance geographically as a "heat map" or landscape of error [1]. Are there patterns visible that could be attributed to local geography, population density, or other factors?

[1] It could be done, for weather.gov [2], using only data available from the web site [3].

[2] I don't really care about the other forecast sources.

[3] To trust rainfall observations obtained from weather.gov in order to compare them to predictions made by weather.gov seems vaguely wrong but there is no other comparable source of observations. They are physical measurements, after all.

[4] Some geographic areas probably have a coarser net of observation points. In some places, e.g., San Diego, the weather is inherently easier to predict. Some local forecast offices may be more skilled than others.
Remembering GW Micro
Imagine if driver's licenses were treated the same way cities treat taxi licenses and liquor licenses.

The number available is limited, so if you want a driver's license you have to wait for someone to die, and then buy the license from the estate. Since it's artificially scarce you'd have to pay a pretty penny to get one. Some companies might step in and buy up driver's licenses to rent them to drivers for only a few hundred dollars a month...

Treating any form of license as transferable private property seems to be against the public interest.

All the things you listed are perfectly reasonable. But, in some regions, the government deliberately issues too few medallions. This means consumers pay higher prices, and all that money goes to well-connected people who managed to get the medallions. Those people don't actually drive the taxis, they just take the money.

Better regulation, like what you describe, seems better than no regulation, but I'd be willing to accept no taxi regulation if it gets rid of the political cronyism and high prices that go with it.
> a gimmick that's valuable only because of a government imposed monopoly is a sound investment

City streets are a limited public good. Aside from ensuring quality and consumer protection, regulation & limiting the number of taxis ensures that traffic can actually flow.
A traffic consultant says that NYC's plan to add 2,000 medallions could slow down all traffic by 12% because taxis don't park -- they roam the streets constantly.

I do hope that you have enough moral consistency that if or when things get nasty, you don't pester your "gun nut" and "prepper" acquaintances but accept the fate your unpreparedness would normally dictate.
Yep. My gut reaction to the phrase "eigenmorality" is to immediately turn around and ask "have you ever seen an eigenface?" (see: https://www.google.com/search?q=eigenface&tbm=isch )

They are a certainly a mathematically accurate way to represent a distribution of human faces, but no one would ever confuse it with an actual human face.

And this is one way i view political/policy compromises (which is ultimately where the rubber hits the road regarding morality/ethics). One example is middle ground positions on immigration reform: http://www.vox.com/2014/6/12/5803912/americans-either-want-u...

There are circumstances where opinions fall into a multimodal distribution, and in those situations, taking a policy position that is the global average not only will piss everyone off, but won't necessarily fix the policy problem at hand.
I don't see why a special set of rules have to apply to just taxi drivers. Isn't working hours regulated already by OSHA? Car safety by the NHTSA? Requiring a pickup might be something that doesn't even need enforcing when there are dozens of drivers in your area.
>They thought the Earth was a flat disk back then. //

Evidence?

FWIW the word here used for "circle" (in the ancient Hebrew, chuwg, [1]) is that used for the arch or vault [a bi-concave ceiling] of the skies; they'd need to also consider the skies to be a disc for it to make sense that it should be interpreted as disc in the Isaiah 40:22 [2] reference. I think the most obstructive interpretation would still need to be something like "dome" - definitely not flat.

So, why not a flat circle? Well there are other words used for that exact thing, as in 2 Chronicles 4 / or 1 Kings 7:23 [3]:

>Now [Solomon] made the sea of cast metal [of the altar] ten cubits from brim to brim, circular in form, and its height was five cubits, and thirty cubits in circumference. //

This is the word for the plane shape "circle" ('agol) that matches the brim of a cup (or giant bowl-shaped altar!).

Note that the figures leaves the brim at 5 - 30/2pi ~= a hands breadth under some interpretations, just as Kings 7:26 suggests. But that verse 7:26 also says that the brim was like that of a lily, not a hands-breadth at the brim but fine and dainty ... and here in lies a very interesting piece of gematria [use of letters for numbers] associated with the Kings passage [4] which in short form encodes in a variant word form qava (=111) for qav (=106) in the oldest Hebrew version of the passage [that in Kings] is the ratio 111/106; the implication being that the true figures should be 30/10 x 111/106 which gives an excellent approximation to pi.
