Yes. There are a few "layers" of crypto in most modern applications:

- Low-level primitives, like AES, ChaCha20.

- Usefully combined primitives, like AES-OCB, NaCl secretbox...

- High-level protocols like TLS and Noise.

- (sometimes) crypto spoken over the encrypted protocols, often for E2E crypto e.g. GPG over SMTPS, or CloudFlare blinded CAPTCHA tokens over HTTPS

This matters because people sometimes think that they're not doing homebrew crypto because they are using e.g. AES. Noise builds on many of the things available in libsodium, including Curve25519 DH, ChaCha20, BLAKE2 et cetera.
> Not quite the same thing in the end, though.

For all intents and purposes, it is. I do not know a single person who I would term "proficient with technology" who is afraid of experimenting or overly concerned about making mistakes when using something new.

In my experience, people who are "good with technology" are always curious hackers and tinkerers who are unafraid of breaking things, and are never satisfied with simply using the tool: they must look under the hood and they must understand how it works.

I would say the same principle applies far beyond computer technology: math, engineering, physics, music, etc...

It's an old Fichtel & Sachs design, from 70s or earlier. I think it came back to production few years back, now by Sram that bought Sachs while back.

I think there also is an old Shimano design, but that was 3 or 4 speed.

I understand your opposition to Eich's donation, but I think that what you said strengthens my point rather than weakens it; my only point was that most tech employees would see an Eich-like quiet, private donation to Trump as a "predictable PR problem that might get away from them and prevent them from effectively leading", and that as a result they would avoid creating such a "PR problem", and therefore we cannot learn much about support for Trump in tech circles by looking at donations.

As to someone somewhere... Show me someone, somewhere on HN attacked by thousands of commenters for supporting some liberal cause in the US the way Eich was attacked by thousands of commenters (who keep mentioning it every time say Brave is brought up) for supporting a conservative cause. (I'm not saying you SHOULD be able to find this example, whatever "should" means; I'm only saying that you CAN'T, and that "someone somewhere" doesn't cut both ways the way you implied. If it were that symmetrical, then it would have invalidated my point.)

I learned rust while I was taking classes so this may be longer than usual, but I started compiling on the first try in about four months. It was my second language though. So if you have learned a language a few times and you aren't busy you could probably do it in a month. That's how long my professor said it took him. And I must say, once you learn rust, it's such a joy.
I know quite a few people who own a Trek 7.2 as a commuting bicycle. It's a great hybrid at MSRP.

You can indeed get a nice bike from a bike shop for $400-500. What you often can't get is a nice city cruiser at that price - the ones I see at my LBSes are often either substantially more expensive ($600+) or cheaper-made without a belt drive or disc brake. I think what's really attractive about this bike is the decreased maintenance requirements (provided it's assembled correctly, which I admit is a big if) and warranty.
They had hard foam tire bikes when I was a kid but they didn't last long. And solid rubber tires are heavy. Decreasing rotating mass on a bicycle is always a good thing.

It is incredibly cheap for a belt drive. I've no idea if things have changed in the last couple of years, but I think cheapest I found in 2014 was around 1000€ in Europe.
Chain drives are about as efficient as you can get, actually. Can be more efficient then meshed gears.. But only if the chain is properly maintained.

Belts may not have pins, but it still needs to simultaneously stretch and compress to go around pullies. The deformation and friction losses add up.

With the solar-powered EV the fact that belts lend themselves to a simple and reliable CVT (constant velocity transmission) probably made up for drive train losses. They could run the motor at the optimal RPM regardless of speed, which can make a huge difference.

With bicycling 'race bike image' and fashion plays a huge role in what people are willing to buy.

People tend to want to spend the money on aping 'Tour De France' bicycles. So high seats and low bars for a 'racing position'. Clipless peddles, high dollar light-weight components... Especially going from 32 spoke wheels to as few as 8 or even 4 spokes are all symptoms of this trend.

And that's just road bikes. Mountain bikes have their on trends with the heavy suspension components used for downhill that soak up all the energy from the rider, etc.

It's the bicycle equivalent of trying to use a Nascar or Class B Rally car for getting groceries. You end up with a really expensive, fragile, high-maintenance, really uncomfortable bike totally inappropriate for touring/commuting/trail riding.

Belt drives don't have a place in racing, so they usually don't have a place in most people's bicycles. The reality is that belts drives are a trade off between maintenance and efficiency.

This Ikea bicycle uses a 2-speed automatic geared hub with belt drive. It features built-in lights and a very upright riding position. It has front disk brake and rear coaster brake (you have to peddle backwards). It looks fairly heavy and ruggedly built.

The advantage of this is that it offers very simple controls and should be extremely low maintenance. It should accept abuse and neglect and run for a long time.

So things like... A family bicycle for running to the local store. Going on flat, level trails. It would be very nice for a 'campus bike' for universities or corporate areas were you spend time going from one building to another. Rental bikes.

It should lend itself to any situation were you are dealing with fairly flat ground, leisurely pace, and multiple people sharing the bicycle.

It won't ruin clothing, it won't spray water and dirt everywhere. You pants are not going to get caught in the gearing. You are not going to have rusted chains or dragging brakes. If it falls over you don't need to un-bend things or re-adjust derailleurs, etc.

The things to worry about this is the same for most Ikea products: Non-standard components, sizing and shockingly cheap components that sabotage the rest of the product. if it uses rugged and standard sizing/components for everything then it will probably be awesome... if not then it could be a turd.
Game Theory Reveals the Future of Deep Learning
Is it really a mystery when the uplink/downlink frequencies are all right in the sweet spot for existing LTE radios?

I'd guess they are going to set up an LTE cell site with "off band" values use LTE modems/radios/antennas on their drones to co-ordinate flight. Get it all working and then go into Verizon and say "hey we'd like to piggyback on your network for our drone services, this is how much traffic, spectrum, and activity you can expect based on our test data ..."
Ahahhhh! That is why every single Windows 7 update since last October has failed on my machine with two installation trials and endless rollbacks! That explains a lot.

This may be kind of off-topic, but does anybody happen to have a link to some explanation of how to fix this without annoying things like unplugging internal drives or fiddling around with potentially dangerous disk tools? I've looked on official Microsoft community websites but they only give fairly useless advice like switching off all antivirus programs and reinstalling the whole OS from scratch.
Noise is a blueprint for a lot of concrete protocols, mostly in the way that TLS has many ciphersuites. While most TLS implementations need to speak most ciphersuites in order to be useful, Noise applications are typically bespoke, so applications using Noise will typically also limit themselves to one ciphersuite and one Noise mode, e.g. Noise_IK_448_ChaChaPoly_BLAKE2b.

So identical to "mixologists" with Reconstruction-era facial hair that make pre-prohibition era cocktails for adults. These are are hugely popular though and seemingly everywhere these days.

Also circuses are for children, thats the target demographic. I don't think a 5 or 6 year old has an "affectation of nostalgia."

Good. Can't wait to see further editorials in Nature talking about all the problems in science (as a community, career, and funding) whilst the whole time meandering around the elephant in the room: they are a _big_ part of the problem.
For all but the simplest renaming tasks, I use "qmv" (from the renameutils[1] package). It loads up the target filenames/paths in a buffer in your $EDITOR, and then you can use the full power of your editor to rename. When you save the buffer, qmv does a sanity check and then does the actual renaming.

Here's a simple example: [2], but it can get arbitrarily complex -- in a much more visual and interactive way than what a shell alone would be capable of.

This is interesting. I never thought of using vim commands to power the browser, but I do love text interfaces. (I type 150 wpm's and find keyboard navigation markedly faster than the point-and-click interface -- especially since keyboards are so much more precise.)

In 2008, back when I used Firefox, Mozilla tried an experimental interface called Ubiquity[0]. It was awesome! I don't know if the plugin still works, but I think text interfaces are really the way of the future for power users (everything old is new again)? Has anyone found anything quite like Ubiquity for Chrome or something like Vivaldi?

Other examples that come to mind: ChatOps[1] (seemingly popularized lately by Slack), Alfred[2], and even OS X's own Spotlight[3].

Nowadays, though, I just rely on the default keybindings of Chrome for most things. One of my favorites is Cmd+L, which highlights the contents of the address bar.

The shell is a tool, as is a proficiency in C, Python, Java, Golang, etc. The more tools you can successfully wield, the more you can build. Just because you're not super proficient in the shell doesn't mean someone else might be the same, so you shouldn't simply dismiss it. It is simply another tool to use and your "when not to use" question can literally be used with ANY technology.

As an exercise, try replacing bash / shell scripting with SQL or C or Python. This is the fallacy in your argument :)
Selling the wrong bike to the wrong person. A casual cyclist should have something that is simple, comfortable and reliable.

High-tensile steal will equate a rough ride. 18 gears and a transmission has a hugely larger number of points of failure, that's just math. And requires regular maintenance, which casual cyclists don't/won't do.

IMO most riders would be best served by Dutch style built-like-a-tank cruisers (which the IKEA is) or lightweight, ultra minimal single speed "hipster" street bikes. But the typical new rider gets a mountain bike for the road, or something designed to look like a racing bike that will be rattling and rusty after one winter.
It's good to see this. As a single researcher it's hard to have an impact and force yourself not to publish to these journals when you have the chance to. But it's horrifying to see that often you even have to pay an extra fee for your online figures to be in color ! That's ridiculous. I hope that other funding sources not only follow the Bill and Melinda Gates foundation move, but go even further.
I read your comment and I can understand your viewpoint.

My opinion is that it's most realistic to make the admittedly arbitrary call that domesticated animals are a historical fact at this point and there's no way to put them 'back into nature.' I think these domesticated animals and pets should be offered the most humane lives possible within the cultural relationship with humans. I try to eat mostly vegetarian but I don't believe absolutism is healthy or a realistic way to live life.

I don't approve of exotic animal pets, mostly because I feel that the animals likely won't fair well under care that is probably insufficient to their needs, and also that they like zoo inhabitants would be better off in their natural (non-anthropogenic) habitats experiencing life as their species should.
I think you should crowd source it. Build a simple two-page site where people can submit censored websites and another where you display them. But your very own website could end up on the list.

Right, and if one cereal decided to significantly discount itself -lose some money for a while - in order to capture more market share, it could lead to a pricing death spiral if the other cereal makers tried to keep up, and people's mental model of what cereal costs went down along the way...
Just FYI, GE Capital didn't get shut down. Some of it was sold off, but it was mostly spun off into a separate company: synchrony financial. But yes, because it was overshadowing the engineering core of GE.
Actually, Vanguard just strongly suggests that their customers do so (and provide nudges in the form of limiting sales and exchanges from certain funds to once per month). They don't get to make their customers follow a Buy and Hold strategy (and their ETF products have no restrictions), so I think it's more accurate to say that they do better (for their customers) due to their relentless push towards efficiency, with low turnover being an important part.

Sorry to piggyback on this post:

I have to use Windows at work, and do not know Powershell. Several times I've debated learning it, but never put in the effort.

Now I use Xonsh (http://xon.sh/). It is a Python shell - cross platform and similar semantics to bash, etc. I was never a power bash/zsh user (scripting in them is Hell). The nice thing with xonsh is that it is Python. If you want to customize your environment, have complex aliases - well, you just write Python code in your config file.

Learning PowerShell for Windows is the ideal. But xonsh is a good intermediate solution for people who don't want to invest in going all the way.

(To be honest, I'm seriously considering switching to xonsh for my Linux machine - currently I use zsh).

Your comment reminds me of being in school in the eighties, and seeing the group think bullies gossiping and shunning a lesbian couple. Daring to say "leave them alone" was met with "OMG you are a queer too", etc.
Fast forward to today, and the group think bullies will rail "OMG you are a hater too" if you suggest you leave religious people alone who have moral objections to gay marriage (or at least promoting it as identical to heterosexual marriage).

Bullies are always the same type of people, no matter the beliefs.

If I remember this correctly, research indicates that if the portfolio is being driven by a random walk process, a stop-loss always causes a reduction in returns (negative stopping premium), i.e., stop-losses are useful only if the return generating process can be shown to not be a random walk.

Also, they tend to mess with your mind (loss-aversion psychology, deep feeling of pain at losses) and make you exit and enter the trade multiple times, adding up to transaction costs, too.

All in all, a) Buy and Hold may actually be quite sensible and b) stop-losses are actually much more complicated than you'd think and seem to be a mathematical rabbit hole.

Stop-losses may make sense in, say, an intraday pair-trading strategy where an analysis of past return evolution clearly shows that winners keep winning and losers are hopeless beyond a point.
I find that most US bike shops fall into two categories - either a general bike shop with a lot of models, or the racing/road oriented that focus on carbon fiber, racing etc.

If you want a general around town bike, I usually recommend the Trek FX series or Giant Escape hybrids. They're a light aluminium, but sturdy, use standard, durable, entry level components, have wider 700c tires good for handling potholes and curbs, mounts for racks - and worlds better ride quality then your run of the mill department store bike.

They're also common enough that you can find them used for under $300, or new starting around $380 or so. Models climb in price as they start adding higher level components but the entry level is usually good enough.

The notion of "backwards" in time is a bit fuzzy once you get into relativity, so the three person example I gave may not clearly show it.

> Unfortunately, on windowed operating systems, this is worse than it sounds, because it creates the possibility of picture-in-picture attacks, where an entire browser window, including its trusted pixels, can be faked [...]

They retorted “Well, we passed this screenshot around our entire information security department, and nobody could tell it’s a picture-in-picture attack. Can you?”

Maybe I'm naive, but shouldn't you be able to detect picture-in-picture attacks rather easily because you never opened that window in the first place?

Additionally, the "chrome" of the picture-in-picture would behave significantly than a real chrome.

I feel both of those points can't be assessed by showing people a screenshot, because people have significantly different expectations when looking at a screenshot of a website than when browsing a website by themselves.

For mountain bikes and race bikes, this might actually be true. I used to have an MTB with stainless steel sprockets. Never needed to change them. Nowadays, they are mostly aluminium, I think. Furthermore newer bikes have more gears typically. The rear cassette used to be 7 speed, now 10 or 11 is not uncommon. This means narrower chains.
Also chain may be lighter now, especially the high-end ones.

Lighter bikes are definitely more fun to ride, but probably at some cost....
