There are a dozen popular live streaming apps in China where one can simply just stream what you're doing to everyone on the site and people can just watch them for hours. You can think of it like Instagram stories or Snapchat per se. Or even Facebook live.

This isn't some western media propaganda. I tried one of them very recently (I don't want to give them any undeserved marketing), they allowed me to sign up and the moment I clicked on my camera button it took me to a page asking me to "verify" my profile as apparently it was Chinese government's new regulation. Guess what? They asked me for my passport before I could upload a damn thing on their app.

Imagine, Facebook asking you to upload your passport before you do a live stream. Only the Chinese government can get away with something unbelievable like these regulations, while still gaining loyalty from their citizens to the point where these supporters will even defend the govt. everywhere online trying to explain how normal it is to submit your passport and your real identity to some random app company because you know, you just wanted to try it out and it's totally normal.
Deep neural networks aren't aware of changes in their own performance, because their cannot remember or compare their own current performance to the one in the past.

What are you talking about? Awareness of the changes is the point of such techniques as momentum or early stopping.
No, you're right.

Numbers i said are my guesses, but the order of magnitude should be about that.

I don't remember exactly how many hash ops you have to do to put 1000 txes in a merkle tree, but it should be more than 1000 and less than 10000.

My point was exactly that. Computational cost of the merkle tree is negligible when confronted with the computational cost of the POW
> Most fuel is used carrying all the fuel around.

That depends very much on the kind of aircraft, and while there are aircraft for which this is true this definitely isn't always the case. Modern aircraft are miracles of efficiency.

Most fuel is used to haul the airframe, cargo and the passengers around, fuel is only a relatively small percentage of the total maximum take off weight.

For example, the A350 mentioned in the article has a maximum of 108 Tonnes (140K liters) of fuel on board and has a maximum take-off weight of 280 Tonnes. So no matter what the mix cargo/passengers/fuel is there will never be more than 30-40% of the take-off weight in the fuel, and a good chunk of that (5 - 7 Tonnes) will be burned just on take-off and another 5-7 Tonnes to get it to altitude. So fully 10-14% of the fuel will be gone after the first few minutes of flight, then once you reach cruising altitude the consumption drops quite a bit due to the reduced drag.

Consumption during take off and getting to altitude varies between about 2.5 and 1.0 times consumption at cruise altitude due to increased drag and the climb itself.

With that kind of penalty on a take-off and the required reserve on landing (which is usually dead weight, but which you will very much appreciate if you have to get to your first or second alternate) the overhead of a landing+take-off sequence is pretty stiff so non-stop flights have a good chance of being more efficient if the destination is in range.
It is not just in our cities...

As my mother pointed out, going electric is removing money from the pockets of the Saudi so-called 'royal family', thereby reducing their capacity to buy bombs and weapons from Western arms companies.

The death toll in Yemen is allegedly 10000 and every motorist with an old fashioned car is currently funding that, albeit by proxy.
> total lifecycle per-km footprint is still substantial without any emissions from charging energy.

The "total lifecycle CO₂-per-Km footprint" is a pointless and deliberately misleading figure when its basis of calculation is (almost completely) independent of the distance driven, but it suggests that driving the vehicle is subject to a high amount of emissions per Km. The opposite is true: EV lifecycle CO₂/Km becomes lower the more you drive.

Besides, deliberately including highly speculative CO₂ amounts from vehicle production and refuelling should be done in all cases: how much CO₂ is emitted by ships and satellite launches used in detection of crude oil reserves?
That's odd, I couldn't for the life of it fall asleep with a headphone near me. I bought one of the Mitch's machines(the neurodreamer) in the past, but I can't possible imagine how someone can fall asleep with a blue blinking LED in their face. Maybe I'm just a little to sensitive but I figured maybe something a little more subtle might make sense.

While the cost issue is still there, AirPods and the ever increasing competing products really solve this entire issue for me, and then some.

I felt they were overpriced but bought them anyways as a birthday gift to myself. Now that I have them though, I would probably even pay twice as much if that was the only way to have them.

They're the single best 'gadget' I've bought in a very long time and even now, six months in, I regularly have little 'moments' where I realize having bluetooth headphones saved me some (minor) inconvenience.

Furthermore, there are pretty decent bluetooth headphones even at forty bucks these days. I'm pretty sure most of us will end up with cordless headphones in the near future.

I don't think it was smart of Apple to go jack-less before cordless was the norm, but then they often do these types of things (non-removable battery/storage, walled-garden iDevices, etc.).

"Promise" is not meant in the strict logical sense. "Promise" can also mean "to give cause to strongly expect", as in "the upcoming thunderstorm promises hail damage".

In this case, it probably means "the investor is reasonably sure of". No, it is not an exact definition, but we are dealing with human behaviour and value judgments here, not mathematical proofs.

> For example, the ability to compile code at runtime is part of the language

An actual Common Lisp implementation does not need to support 'compile' for the application, when it is not needed at runtime. Actually if the CL implementation is only an Interpreter, then COMPILE is a no-op.

Take for example LispWorks, they have a compiler which creates an iOS library which is linked into an Xcode iOS application. When you 'deliver' (means: creating shippable code) the Lisp system removes the compiler (and potentially all kinds of other stuff). Generally the Common Lisp compiler/runtime to iOS/ARM code supports the whole language, without the runtime compiler.

This 'Delivery' tool is also used on other platforms, not just for iOS.

You must abstract a bit from what the language standard describes and what actual implementations do or support. If somebody wants to deliver static/restricted applications with Common Lisp, then he/she would just use a Common Lisp system which can do that, regardless of what the standard says or requires.

Ask HN: I just discovered a new algorithm. What should I do?
Hi HN,

For a robotics problem I have, I needed to determine the minimum distance between a point and an ellipse.

Existing stack overflow answers suggest using root finders to solve a quartic equation or specialised iterative methods that have instabilities.

https://stackoverflow.com/questions/22959698/distance-from-given-point-to-given-ellipse

One paper suggests using an initial guess on the ellipse as a root of the quartic, using the guess to simplify it to a cubic, and then solving it. The result is a fast converging stable algorithm, but solving the cubic and choosing the correct root is gross.

I've come up with a method that relies on maths that most programmers would not be familiar with, but the implementation boils down to 14 lines of python. It converges quickly (3 iterations) and is completely robust (no divergences or divide by zeros).

This is the first time I've been sitting on an algo that I genuinely believe to be novel. The robotics is a side project and work doesn't lay claim to IP outside of work.

I intend to write up a blog post tomorrow, but if you were in my shoes what would you do?

Thanks

AdNauseam is just not a good approach to malware/ads/surveillance blocking.

The creators clearly haven't been on both side of the ads spectrum: As content creators and intrusive ads blockers

They don't know the inside of this market enough, they don't know what happens when a website get it's ads clickbombed

Some websites really have no other way to finance themselves other then using ads, and use not intrusive ads network and AdNauseam will just get them banned

AdNauseam is just about wrecking avok publishers revenues by getting them banned from ads networks, so like always, it's the small publishers that will get punished, and not the big shit ads companies.

Buzzfeed-like companies will find a way to counter AdNauseam,they have the ressources for it, but not the smaller tech blogger that you like reading

I wrote something about it a few months ago:

My biggest beef with the new MBP TouchBar is how horribly slow Keychain has become.

* When a login form is shown in Safari, it takes 2-3 seconds before the username and password are prefilled. Safari just hangs (beach ball) in the meantime.

* Searching in Keychain Access is horribly slow. After a search term has been entered, it takes 4-5 seconds before the search results are shown. Keychain Access just hangs (beach ball) in the meantime. And it is made worse as searching also starts during typing, so you can type... but the text won't show up. And Keychain Access simply hangs. And after the 4-5 hang is over, it starts hanging again as you've entered additional search terms.

* In Keychain Access when you've finally gotten to the entry you wanted, copying the password to clipboard is another 2-3 seconds wait. With appropriate hang (beach ball).

This has been going for many users on this machine. Apple doesn't confirm that this issue exists, keeps suggesting to reinstall their machines and offers replacements to others -- which obviously doesn't help. Users testing macOS High Sierra beta's report small improvements, but still nothing significant.

[speculation] I suspect the Secure Enclave is to blame here, some design issue with the hardware. High Sierra appears to do heavy caching of the Keychain, to work around this hardware issue. [/speculation]

[edit]
Issue #2 with this machine is that Spotlight randomly stops working. You can open Spotlight (CMD+Space), but you can't type your query -- it doesn't respond to key pressed. You have to `killall Spotlight` from the Terminal to fix this.

Issue #3 with this machine is that the keys are too close to the screen when closed. You can see an "imprint" of the keyboard when opening. This will probably cause damage to the screen's coating in the long rung and thus reduce the machine's lifetime (damaged screen).

Issue #4 is flaky Bluetooth radio. Multiple times throughout the day my Apple Magic Mouse, Apple Wireless Keyboard and/or Sony headset will disconnect.

Issue #5 is slow wake from sleep. I've had multiple wakes from sleep taking over 20 seconds -- leaving the screen black while resuming. The repair center blames high memory usage (paging). However my previous 2013 MBP (also 16 GB) didn't have the same issue, and my use hasn't changed.

Issue #6 is that the machine sometimes crashes when plugging in the Apple USB-C HDMI Multiport adapter. That's a great start of a presentation having a room full of people.
Any normal reading of English would understand a world before electric cars, and a world after electric cars, as having moved pollution. We're talking at a higher level of abstraction, where the mover is a change in the mix of polluters.

It seems obvious that since this would damage Google, Google will defend themselves by detecting and blocking this kind of traffic. Optionally they may also suspend accounts.

Yep, you're totally right. Different country and different product but if anyone is unsure what features these tools have available they should read that wikipedia page.

We all knew at some point it would be used inappropriately and we'd all be responsible in some way. I think schools and their departments are right to move away from these types of tools. They're teenage kids, not some domestic terrorist with an enormous network.
> You can't just scale the number of transactions in a block forever and still have a stable currency.

If you mean that over time the incentive to centralization become stronger, yes, you are right.
There must be competition to enter the blocks, otherwise when mining subsidy ends, there will be no incentive to secure the ledger.

If you mean that ten times the transaction have a computational cost 10 times greater (or 5, or 2), you're wrong.

> The whole point of the system is to verify transactions and it stops working if it doesn't do that.

Plenty of cryptocurrencies are mining tons of empty blocks. on the short term, if there are no transactions, mining continues with the same difficulty.

The effect is long term: if noone is using the currency for transaction, it has no value so less and less people mine it. The difficulty drops, and the security drops, pulling value down even more.

You are almost right, but it is a very indirect effect, and takes years to manifest itself.

Congrats on the acceptance into boost. As a user of boost, I will definitely look at this.
To be fair, I pirate video despite Netflix and other services because of the poor catalog or bullshit like region blocking.

I've stopped pirating music though - Spotify became good enough for me to be worth it.

So no, I bet a majority of your "pirates" will stop pirating if there was a decent legal alternative.

Does it actually work? I might try it.
While I also like TouchID, I find that the implementation of software wise is half-assed though. For example; the login screen won't show the password prompt until you entered the first key. So if you wake the machine, you don't know if the machine is ready to accept your input as you can't see a blinking cursor. While this would make sense if you alway use TouchID -- no need to enter your password right. But when using in clamshell mode (lid closed), it STILL won't prompt for a password. And you just have to guess whether the machine is ready, or still busy waking from sleep.

I like the product. But I wouldn't invest in automation of all the stuff upfront. I would just process the upload/order manualy for a couple of first users just to validate an idea financially.

From my experience people fear more of success than failure therefore overdo the product to survive an imagined scale explosion. But there wouldn't be much outrage from users that once flooded you have just raised the prices or temporary suspended the service. I guess queue with bucks in front of the door would boost your motivation to finish up the process implementation in half of the time.
You can lead from the front, carrot in hand, rather than sitting in the back with a whip. I've worked every bit as hard, and far more productively, for technical leaders who were visionary and inspirational rather than cruel and machiavellian.
You should try using a thunderbolt 3 adapter. One Thunderbolt 3 port supports can support up to two displayport 4k 60hz port. If the macbook pro has a dedicated TB3 controller per TB3 port then it could in theory support up to 8 4k 60hz displays.

https://www.amazon.com/StarTech-com-Thunderbolt-Dual-Display...

I don't understand the USB-C hate. Especially complaints about applereplacing it in 5 years with a new port anyway. With displayport 1.4 over USB-C we will soon be able to drive 8k montors at 60hz with a single USB-C cable. USB-C is truly the "last port".
I think what they meant was that the touch bar is essentially a whole separate computer with its own ARM chip, running a modified version of WatchOS, communicating with the MBP.

A couple of years back I tried being nice to sites that asked me to unblock them and found pretty much all of them running tracking, malware and worse yet enough javascript to make the sites totally unusable with the small n2806 celeron/2gb system I use. Not any better on the other 2955u 2gb system either. With adblockers these 2 systems work just fine on the internet.

In the early days of home computing and the early days of the PC it was a common requirement to roll your own cables. Getting the pin-out of a parallel port soldered up correctly was not so simple, even RS-232 serial cables were harder than the USB to get right.

I can't fully remember why it was required to make such cables on a regular basis but it happened. It seems that USB has not only made cable soldering a lot easier it has also removed the practical need to do so. Either that or I am no longer a 'hobbyist' with interest in such things.
Good points. I'm not particularly interested in monetizing the algorithm.

I think I'd like to be able to point to it the next time I go for job interviews. Another possible goal would be to try publish something formally to help with an O visa (or international equvilent) should I ever need one.

Thanks
It's too late.
This advertisement terror has gone too long. Now we have a quite good infrastructure to block ads and the advertisement industry will have to come up with something really fantastic to get us back.

The methods people who rely on ads put up to counter that, will just hurt them because pointing the finger at the user of ad-blocking software is the wrong direction entirely.
It always seemed weird to me that the Concorde was a British-French thing whose chief routes was between London, New York, and Paris.
