Looks like, at the moment, they don't support deposits or withdrawals of the cryptocurrency you're trading, so if anything, they seem more like ETNs of the cryptos than the actual cryptos themselves?

I imagine it's for the reason you stated until they get the security protocols in order. Not sure how they're getting around SEC approval, unless it's something sort of like an IOU loophole where you can only sell the IOU, but not redeem it for the coins yet per their terms of service?

I have no clue.

Hi Jordi!

libgccjit is in maintenance mode: I believe it has everything you need if you (or someone else) wants to implement a JIT for GNU Octave (or for any other interpreter)- I just don't want to be the person to do that, as I have enough on my hands with GCC work; I can't become an Octave maintainer too...

I'm more than willing to help answer questions on it if you or someone else from the GNU Octave community wants to do it (are you doing Summer of Code this year?)

1. They cannot claim they discovered constructive/destructive intereference

2. They cannot claim they discovered interference that shifts frequency.

3. They cannot claim to have "Reverse engineered the Cuban "Sonic Weapon" attack"

They instead PROPOSE the U.S. Embassy in Cuba has brain-altering levels of noise in the ultrasonic region somehow caused by two or more simple,low level and possibly common ultrasonic emitters without malicious intent and THAT'S why some people can hear it...

Xu's other recent works has been lacking meat and are better at fear-mongering (Tesla ultrasonic 'hack', Smart grid 'hack').

Xu's ultrasonic Tesla 'hack' showed how dangerous the pedestrian avoidance system was by wrapping one of her graduate students in Michelin Man-sized ultrasonic dampening material. Tesla had to make an uncharacteristically brusque comment stating they couldn't reproduce anything of risk to Tesla drivers in the world.

She is the equivalent of the National Enquirer in the security research world and steadily increased her ability to clickbait.

A few years ago I was working with a custom builder on a house plan (that we didn't end up pursuing), but one of the things I suggested was future proofing the garage for electric cars. Given that a Tesla can charge on 80 amps, it seemed reasonable that a two car garage in a custom home should have 160 amp service. It may not useful right away, but it would very probably be useful over the life of a home.

He thought I was crazy, and maybe I was. But articles like this make me wonder.
Had to look it up, but I paid a bit under $5 in total last year. Mostly towards the beginning of the year when I didn't have my bills set up properly (i.e. the timing didn't match my direct deposits at first, had to make some calls to change that) and from some large ticket purchases that a single paycheck couldn't fully cover (with sufficient planning those could have been avoided if I sold some stocks beforehand). I haven't needed to make use of margin at all for well over 6 months now.

Schwab's margin rates are on the high side, starting from 7% and up, but even then if you're borrowing for 2 days at a time the cost ends up being negligible (about ~$1 for every ~$3000 borrowed). At the very least, it's much better than most overdraft fees/lines of credit. Though if Interactive Brokers were to offer a bank account, I'd be very tempted to switch with their amazing margin rates.
"Just try to start marketing a proprietary privacy-oriented messenger app or something like that and the intelligence guys will emerge promptly at your doorstep, demanding you to bake a backdoor in"

Nope...Been making one for 3+ years, worked on high risk human rights type stuff for over a decade and never happened.

Surprisingly most people doing things in this space don't have g-men kicking in the door. Live in UK, Ireland and many other countries and hasn't been an issue.

Might not seem real to a lot of people who are affected by certain biases but most Western government type people we meet at conferences etc are actually quietly supportive and respectly agree/disagree with what we are all trying to do. Not eveything is a black or white echo chamber - we are all citizens who understand nuance (for those of us fortunate to live on free countries - of course Turkey is no longer anything near that.)

FWIW Protonmail is very useful for a large chunk of threat models were security is pretty high but implementing PGP in all its various forms is a pain the ass.

Playback speed is adjustable so I wouldn't stress too much about it.
Personally, I get the most mileage out of Google's voice assistant when I'm driving.

It's a situation when I can't (well, shouldn't) use the phone's UI, so it's great to ask it to:

-find a place and check its hours of operation

-navigate to said place

-find a gas station along the way

-etc.

On an occasion, I've asked it to add things to a calendar.

As a lazy person, I prefer to do things with the minimal number of steps. Scheduling things in a calendar requires an inordinate amount of clicks. On the other hand, it's something that a CLI could be well-suited for. For such things, voice control is natural.
How sure are you that you really think that way? Most people make decisions based on emotion and intuition, then rationalize those decisions after the fact and fool themselves into believing they were rational from the start. Since human memory is so unreliable it's almost impossible to accurately determine which decision making process you actually followed.
Things Everyone Should Understand About Tech
An earlier version of this work was discussed at https://news.ycombinator.com/item?id=16515552.

Since commenters here are objecting to the article title as misleading, we've replaced it with the subtitle (with s/Havana/Cuba/ to fit in 80 chars).
Probably javascript. With the caveat that all of the work I've done in javascript has been of the old school "write it in a text editor and FTP it to the server" variety, and I have little real exposure to the modern ecosystem or the problems people seem to have with javascript at scale.

I like the simplicity of the syntax. Arrays and objects are easy, closures are easy, and I like prototypal inheritance as a concept, although you're not supposed to actually use it in practice.

Lua is probably a close second, though. If I were to design a programming language, it would probably be somewhere between the two, with some C++ features tossed in for flavor (operator and function overloading, maybe generics.)
Python - because I suck at programming and it's easy - also because I don't do it professionally it's more of a hobby for me
Most of the long-horizon reports that I read centered around Spectre 1 (intra-process OOB reads by racing bounds check against conditional branch prediction, currently mitigated by lfence), which is still a fundamental-principles issue that would be exceptionally challenging to solve without either substantial performance loss or some form of userland/compilation-level workaround. Intel still haven't indicated a hardware fix for that one. I expect that most mitigations for this will center around improving static analysis tooling and giving the compiler finer-grained control around fencing to reduce performance impact.

Variant 2 (branch target injection, retpoline style software mitigation) is the most interesting. There are certainly obvious theoretical hardware mitigation strategies like tagged BTB entries and this is the most interesting hardware fix. To me it's very cool but not particularly surprising that Intel believe they'll have pure-hardware mitigations for that soon.

And Meltdown was frankly an Intel mistake that would have been shocking if left unfixed in the next hardware revision.

If you are experiencing corruption issues you are likely using a USB power supply that is not sufficent, for the rpi3 you need at least a 2.5 amp supply to ensure reliability.
Yes, this is the Kristen Stewart from the Twilight movies, and I found the background on this very interesting.

> Less well-known is her interest in AI, laid out in a new paper on the use of the technology to create art in her screenwriting debut, Come Swim.

> Stewart’s starting inspiration point for Come Swim was one of her own paintings. The paper describes the filmmaker’s experiments with style transfer, a popular use of machine learning that transforms one image into the artistic technique and color profile of another. Stewart and her producers used the technology to turn scenes of Come Swim into the style of Stewart’s own painting.

Fascinating! Thanks. That was largely ignored in US media, as far as I know. But then again, the average American knows next to nothing about the EU.
The paper explains it's because they want deterministic destructors for things like file handles.
You make a good point about new engineering skills needed for cyber. There are also institutional issues. Software talent tends to be in the IT department, and power systems talent is in the operations and planning department, so issues like cybersecurity require a lot of coordination now that controls are networked and highly automated.
>> Put an Englishman, a Norwegian, and an Italian in a room together and it is more than their accents that tells you who's whom.

Unfortunately, that's very difficult to know for sure, for instance because you can't just take the accents out of the people and see if you can guess their nationalities from their behaviours.

Also, I don't know how you can tell that the differences between an Englishman, a Norwegian and an Italian are due to their nationality and not just the difference in personalities you'd expect to see between any three people- say any three Englishmen or Italians etc.
> Couldn't they obtain a 7khz tone by mixing any two tones seperated by 7khz and applying a low-pass filter?

I don't understand this comment. Are you implying that a low-pass filter would shift the frequencies of part of the signal rather than (mostly) filtering some of the frequencies away...?
this hasn’t been the case for me. I see recent purchases online and the app for purchases in store with a physical credit that is also used for Wlmart pay. Even if I didn’t use Walmart Pay for that purchase. I wasn’t to happy to see non Walmart pay purchases automatically added and there should be an opt in (at minimum an opt out) for this association.
Well, I do remember something anecdotal about a sound frequency that can make you poop. Apparently, it stimulates the bowel muscles.
Oy. Odd that's missing from the headline since it changes the context from "passionate" to "psychopath".

The story seems balanced, but the headline is too generous.
Jobs set the tasks, often demanding very specific inventions and advances - plug and play networking for NeXT, a vastly cheaper mouse mechanism, etc, etc. Only in hindsight can those marked advances be taken for granted. Often very correctly. He was an engineer, starting on the front line as she did, just not the best - I don't know that she was, either.
Ah. Wow.
You already have a desktop version of Robinhood available as an open source - http://bit.ly/2FJXl7b
A low-pass filter would filter everything out assuming the threshold is below the two frequency. The beat frequency of the two tones would indeed by 7kHz, but if you think of the resulting waveform, the contingent parts are smaller, faster oscillations that that would be suppressed by the filter.
I know this isn’t what you’re referring to, but DOE is pushing for a reorg that creates a large cybersecurity department.
And this is what limit orders are for. Disclaimer: I'm a robinhood user, who also works for a large high frequency trading firm. You're spot on (well that and robinhood gold is how they really make their money).
>And if nothing else, it should help to debunk the conspiracy theories that would inevitably pop up, he said.

I think this is the exact opposite of how conspiracy theories work.
Recreating a book forbidden by the Spanish government from El Quijote
I can understand why they guide people towards investing in "hip" companies versus an index fund, but regardless why is their so much animosity towards robinhood on HN? Is someone getting into investing and investing in an Apple/Amazon/etc. not overall a pretty good entry point compared to opening up thinkorswim or the pretty atrocious (at least on mac) schwab desktop client? Investing a small amount of money is better than blowing that money on tons of consumeristic bullshit that that tons of people do and RH seems like a genuinely good stepping stone compared to the current incumbents in a lot of ways (fees/minimum deposit/super simple). The fact that you can even start with RH and then at a later date transfer to a brokerage once you have a large enough portfolio is also a huge plus in my opinion to people who may have otherwise never set aside that money in the first place.
I believe that RH is actually making their money off of the interest on spare cash in accounts. You can do limit orders in the app if you are particular about price. I don't have a source for this, other than I like the app.
If you're #50 in the PGA in terms of average ball speed [0] and drive a regulation ball (46g)[1] at 175 mph (78 m/s), that ball has an energy of 140 J. If it accelerated from 0 to 78 m/s in 0.5 ms [2], it accelerated at 156 km/s^2 for that short time, at a power of 280kW (375 horsepower). The force applied to the ball was therefore 7100N, corroborated here [3].

A driver is 45" standard, but assuming that you don't hold the club at the tip we can call it 42" or 1 meter. You don't rotate the club where you hold it, but rather roughly at your shoulders (I will neglect hip rotation), and the average arm length is 25". Arms are not locked straight so let's call it a little shorter, and add 0.6 meters for the arm length.

You now have a 1.6m moment arm applying a force of 7100N through the ball, requiring 11.4 kN-m of torque, or 8400 lb-ft. Edit: I have discovered that wrist torque is significant, and that your wrist and your arms individually supply about 150 and 400 N-m of torque respectively. [4]

To compare, a high-end sports car might have 500 HP (compared to the golfer's 375 HP), and the Tesla P100D has 920 lb-ft of torque.

Of course, the golfer sustains this output for only half a millisecond, and a lower output during the rest of the swing (around 1 second). A car can do it until the tank or battery is empty.

Also I have neglected hip rotation, differing driver and arm lengths, and energy loss due to deformation. But this is a decent first approximation, and at very least in the correct order of magnitude.

Am I the only one who finds this whole logic upsetting?

We're on the verge of a mass species extinction event and with the news that efficient electronics are in fact using less energy is somehow bad news.

The profit motive doesn't work for utilities...well it does most of the time, but this is a clear example of when it doesn't.
You definitely raise a valid point, but as I mentioned in reply to a sibling comment, I do try to prepare in advance for big purchases like those by selling off stocks to pay those off in cash. I would never deliberately use margin as a financing option due to those dangers you mentioned.
It has a good ide.

It's unacceptable in principle. If a wall street model is right more than it is wrong then it wins. If police are wrong half the time we have a big problem on our hands.

Nobody makes all the right calls on wall street. Some just win more than they lose.
In a wider view, I agree. But I'm not feeling terrible about using the term for someone that offs their own children. In what context is that not some serious and notable mental disorder? Is "sociopath" somehow kinder?
Not upsetting. It interesting, really. Finding ways to economically rationalize good climate behavior. You no longer need to ask people to install renewables to save the planet; it just makes plain economic sense [1] [2].

Utilities need electrical usage growth to offset consumption stagnation (and occasionally, structural and energy efficiency declines). That growth will occur moving ground transportation off of oil. If that creates an unexpected coalition, why not roll with it? It'll increase the EV uptake rate, it'll ensure transmission infrastructure still sees necessary upgrades and investment, and because vehicle charging can be structured around time of day metering, they're a perfect mix for more renewables being added to the grid.

EDIT: OP I replied to should not be downvoted. The situation really is dire [3]. At our current renewables deployment rate, it will take 400 years to swap out all fossil fuel generation; we can and must do better, but we're going to have to properly incentivize action and rapidly increase the replacement rate of fossil fuel generation.

It goes beyond the runtime: the way we describe work in progress as "in flight" is somewhat irritating. I've caught myself using this quite a lot recently: I first heard it used around 4 years ago. Since then it's somehow wheedled it's way into my daily lexicon. It's a habit I'm trying to break.

Very timely, I just spent the last two days getting Eigen, BLAS, Suitesparse, and Ceres playing nice together on Windows. I recognized the GEMM call from the Cmake module that checks for BLAS. Amazing the amount of work and optimization going into these libraries that underpin countless of today's leading ML and CV programs.
That's a good solution, but college-level mathematics was specifically where I had issues learning the material myself. I remember taking an upper-level college class for my cs degree that focused heavily on proof-based mathematics. I decided I wanted a tutor. Online tutoring for the highschool/lower level college classes was easy to find. But not for upper-level proof based math classes that were TA'd by grad students. I finally found one company that was willing to tutor me. They advertised tutors from ivy-league grad schools and started billing at over 100/hr. Fortunately I found a grad student to to tutor me at my university for a much more reasonable price. But I definitely noticed a difference in the type of tutoring offered. I'm much less confident self-teaching myself mathematics if it involves proofs, or material that would show up in grad school or an upper-level undergrad class.

> My concern is that overall, the product and marketing seem to be geared towards speculative, short-term trading. When I first signed up, the app was recommending that I check out stocks like Apple, Netflix, and Snapchat, not index funds.

There's a broad spectrum of public companies obviously, but it's hard to see $AAPL as speculative in the same sense that people call penny stocks or cryptocurrencies speculative (i.e. much, much more risk involved in the latter two). Investing in large cap equities isn't the stupidest thing you could be doing as a new investor - that award would certainly go to buying derivatives.

And indeed if I have criticism of RH it's that they're trying to appeal to all investor types at the same time, new and experienced alike. It's easy to see how new investors can get confused when RH offers the ability to sign up for cryptocurrency trading and options trading, two things new investors obviously should not be doing (though admittedly there's obviously a questionnaire involved before you can be approved for options trading, not sure about cryptocurrencies).
The Spanish government has forbidden a book called Fariña as some politicians have requested so. They seem to be involved with drug traffic.

No, obviously not but this article isn't talking about overarching economic goals. It's talking about losing technical dominance to China and my point was that the dominance seemed to have been helped by the trade practices, not hurt by them.

It also doesn't help children that do understand what is being taught to have to repeat basic concepts multiple times for the benefit of children that are slower. Intelligence, physical ability, beauty are not distributed evenly about the population of humans. Pretending it is for the sake of feelings is foolish and short-sighted. If we could be adults about the facts and foster each individual's strengths and weaknesses without being cts to each other we would be much better off. Why is intelligence such a touchy subject??? Some people are short, some tall. Some fast, some slow. Some smart, some dumb. It doesn't make them any less human. And denying that certain identifiable groups have clusters of one or the other attribute around their genetics is equally unproductive. Obviously it isn't deterministic in EVERY individual but its a starting point. Give everyone a chance but please stop pretending that everyone is the same or capable of the same things. Human biodiversity is real
