15$ without benefits (health insurance, retirement, etc) comes to 2500$ per month if working 40h week. Doing much more than that is hard if you are truly developing. Then you have to pay for health insurance, and save for retirement. Your net pay will end up being be far less than 1500 euros.
Full body PET/CT scanners already exist but they can only scan slice-by-slice. This one creates an image in real-time of the whole body in 3D.
PET scanning is invasive because it requires the injection of a radioactive tracer. The scanner actually records simultaneous gamma-ray disintegrations. There are many available tracers allowing to measure for instance glucose metabolism, which is great for oncology (cancer medicine). This is currently the most precise way to detect many cancer lesions, particularly lymphoma, cancers of the lymphatic system. Other tracers can be used to measure for instance blood perfusion.
This scanner is also interesting because it is less wasteful with gamma photons. This means that less tracer can be injected for the same image quality.
- I'm not aware that you can typeset whole documents, including mathematics, in the Matlab UI. see nbviewer website - I'm not aware that you can do slideshow presentations in Matlab, using something as simple as markdown. - Plots and graphics are not embeddable in the Matlab command line.
On the other hand you can use Matlab as a GUI builder, which you cannot do as easily with Jupyter. see dashboards in jupyter
I've been using Apple routers for a long time with mixed results. The express line is simple but not fast or very robust. ISP provide their own wifi routers now, so why bother? My time capsules have always failed (typically shortly after the warranty period expired) so now I'm just using a large NAS.
How many billion miles travelled per day? The relevant statistic is the number of fatalities per billion miles (or km) traveled. See here. We don't know for sure the relevant statistics for driver-assisted vehicles.
There is a very good chance that driver assistance is going to improve the fatalities statistics, but this needs to be done correctly.
Some hardware gets cheaper some of the time. I've noticed for instance that the old-fashioned mechanical watches that were the staple of the last century have not gotten any cheaper at all. Recently the price of high-end GPUs has skyrocketed.
Mass production of some goods can cause them to become cheaper but this is by no means a foregone conclusion.
Not exactly, you are describing the hidden-variable theory that Einstein favoured. This is not what Nature is doing. With quantum entanglement, here is what happens (simplified):
The color of the marble is a combination of RGB values between +1 and 0. This mean your marble could have a Red component, a Green component and a Blue component. So it could be totally black or totally white, it could be also blue, red, or green but also magenta, yellow and cyan. However, you cannot observe the three colours simultaneously. You have to decide whether to look the blue channel, the red channel or the green channel, or at your convenience, a fixed linear combination of all three. You have no idea regarding the true Color of the marble whatever you do.
What quantum mechanics says is that if you have in your two boxes two entangled marbles, one on Earth and the other on Alpha Centauri, their colours are not fixed until you observe them. And then you have to decide what channel to look for in advance.
Say that you and your friend decide ahead of time to look at the green channel. Quantum mechanics says that at the moment that one of you look at that channel, then the other will see the negative of this observation. If you observe that your marble has a green component (it may then be pure green, or white, or cyan, or yellow) then the other observes that it does *not* have a green component (it may be black, pure red, pure blue, or magenta).
However, the other components are not only unknown, they are actually random and not related. In other words, the observation disentangles the two marbles but only fixes one of the components. The other components are chosen randomly and are not related.
Einstein thought that if you observe one marble, all three components would be flipped between Earth and Alpha Centauri. I.e if the marble on Earth was actually cyan (blue+green) then the other would be pure red, but this is not what happens. Only one component is flipped, the one you actually observe first, and the observation causes the flipping. The flipping is instantaneous.
I'm simplifying a great deal. In reality one observes a spin with 3 components and only one component can be observed, but it is not binary, but essentially this is similar to what happens.
Rewriting history. Elon said the problem was easy to solve in 2015, and that he would let his car drive him coast to coast before the end of 2017. Basically he was saying Tesla had an autonomous vehicle technology that was just around the corner.
I'm with you that they never said that this technology was implemented in their current cars.
Not really no. Deep artificial neural networks are very good at some specific, well defined tasks like playing Chess or Go, or recognising faces in good conditions. Car driving is so far too complex.
NIH syndrome and Hubris. Tesla did use the Israeli Mobileye technology (now part of Intel) for a while until the fatal accident with the trailer truck, see here for instance.
The Renault Zoe can be had in Europe for 7k€ used + 70€/month for renting the (new) batteries. This opens up the market to a large number of buyers. A 35k€ car is way to much for the vast majority of households.
AMD GPUs are popular with Open-source rigs, especially since the OSS driver performance is on par or better than the closed-source one even on recent GPUs. but several things play agains AMD becoming more popular on OSS rigs.
GPUs are no longer used only for gaming. For instance AMD GPUs are more efficient at crypto-mining, meaning that there is a premium on them and stocks have been low. This is great news for AMD by the way but not so much for gamers. Meanwhile Nvidia has been investing a great deal in GPU computing for scientific applications, especially these days for deep learning. Most DL frameworks only support Nvidia, including big-name ones like Google with Tensorflow.
Backblaze is a backup service company. Basically, all they do with their drives is put them up in a bespoke cabinet, slowly fill them up with data at internet speed, then let them running for a long time doing hardly anything at all. Infrequently, when someone loses some data somehere, they read a small portion of them. This is very far from what most people do with their drives. In particular read/write performance and reliability does not matter to Backblaze.
QED nothing. This dates from 1990 and has completely failed to deter millions of people to learn the language. Now Tom Cargill could put together some extra words involving templates and meta programming, which would still prove nothing.
In plain english you can make sentences that are legal grammatically but have no sense. This is an instance of a feature in a computer language that exists, is legal, and that has no recorded actual use. So?
C++ is a universal language that can express very abstract computing, and has tight speed and size requirements for it resulting code so that it can be used in embedded application, operating and critical systems. One day someone will produce a formally verified C++ compiler (such a C compiler already exists), and it will be a safe language too.

Your own car can now serve:
1- As an automated kidnapping device
2- As a weapon in any violent crime
3- As a bargaining chip against you in any negotiation
It can also handily be repossessed easily, all of the above at a small cost in hacking. Basically a terrible idea.
How about AI that doesn't require GPUs to train and run? These are terrible for the environment.
Not quite.

For some reason people find the method you mention messy.
An excellent point.
Debian is not derived from RedHat. Debian 0.0.1 was created in 1993. Redhat first release was in 1995.
Every major distro uses systemd now. By all means, feel free to use any of the init-based distribution if you feel strongly about it.

Compared to petrol, electricity is free. You can fill an electric car for 400km for 2 euros. Currently this is like 30€ for petrol in Europe.

How long ago did he reserve it? Say I want to buy a new Model 3 from Tesla today. Can I do that? How long to I have to wait?

Very good but not that good yet, aside from rigged demos.

Interesting perspective...
Others have pointed out that it should be able to break a 21-bit key (half the number of qbits).
