> To the best of my knowledge there are zero remaining manufacturers of CRTs in the world.

I have seen plenty of stores selling (small) CRTs in stores in Asia. They are usually quite small, and I bet they are quickly disappearing, but they are still around.

> There are only three trillion dollar industries in existence: energy, high speed transport, and communications.

I would suggest that housing is a 4th trillion dollar industry.

Unfortunately your map has cropped out several countries, included where I live. Do you have a copy that has Fiji, Tonga, Samoa, New Zealand, New Caledonia, etc?

Perhaps he means 79% of the cost, rather than 79% by mass or volume.

In similar systems, the position is generally tracked with the combination of interial sensors (accelerometer / gyro / angular rate sensors) and external references like GPS and star trackers.

Inertial sensors are able to provide high frequency data on change in position and orientation. Higher frequency means the software can make much more rapid decisions to steer the rocket, on the order of 1000 a second or so, much more often than can be achieved with GPS.

The fact that inertial sensors don't rely on external signals (like GPS does) means that there is some degree of robustness- for instance, if there is a temporary disruption in GPS signal reception, the rocket will still have some idea of its position.

Over time, integration and measurement error accumulate from the inertial sensors. (Remember that they generally measure changes in position / orientation, not absolute position or orientation). For this reason, it is usually necessary to use external position and orientation references to correct the error that accumulates over time. GPS is used for this, and in some applications, star trackers can be used as an absolute orientation reference.

On the algorithm side, a Kalman filter combines measurements from all of the position and orientation sensors to generate a prediction of the current position / orientation / velocity / acceleration etc.

Flow chart is really cool!

I wonder what the biomass used for transportation is?

I just had the top case replaced in my 2016 MacBook Pro 15, and they used a top case from a 2017. The tech confirmed that they use the 2017 top case for 2016 models, but the 2018 top case isn’t compatible.

The 2017 does have changes vs the 2016 to make it quieter and less clicky.

The age isn't the only explanation for the low data rate- it's not simply low tech.

GPS relies on receiving extremely weak signals, often with a very limited receive antenna. This means there's a real trade off- you can send a limited amount of data over a given communication channel. Increasing the data rate might require increasing the transmit power / antenna gain of the GPS satellites, or requiring bigger / better receive antennas on GPS receivers.

Here are the parameters involved: https://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theore...

Starlink is planning to deploy at 550km according to Wikipedia.

Is there a library available where a person could use this algorithm for text-to-speech? What is necessary to generate the input features for this algorithm?

I bought a first gen Apple product (against conventional wisdom), and seem to have gotten a lemon.

Most of the stuff was not avoidable- image retention on the screen, worn out battery, defective motherboard, etc.

My US-bought MacBook has been fixed under warranty in the US, Canada, Thailand, and Singapore.

There are some country-specific restrictions- here in Mexico, they are unable to fix Apple products from other countries sometimes due to government restrictions; e.g., they were unable to replace my girlfriend's iPad screen at any price at the Apple Store since it was bought in the US.

The whole OS seems more snappy to me. Wonder if they have somehow figured out how to file access latency? Perhaps less of the filesystem metadata needs to be accessed on each file access.

I'm currently a customer of https://www.usglobalmail.com , just one of many services like this. They scan mail, can throw it away for you, and can repack / reship packages.

If cars upload their data, as well as data about other cars detected in their environment (e.g. positions of other detected cars), we could detect the suppliers of false or incorrect data by comparing data from multiple cars in each situation. It's not perfect, but could be a step in the right direction.

They have decided to rewrite the C parts of NumPy in RPython, essentially working towards a pure Python version of Numpy.

There are a lot more details sprinkled across several pages: http://morepypy.blogspot.mx/2013/11/numpy-status-update.html http://pypy.org/numpydonate.html

Clang can tell you why a loop wasn't vectorized with a couple of compiler flags:

This cable might actually have quite a bit of metal armour on it to protect the cable from damage. Here's a picture that came up earlier today, showing rigid metal "caterpillar" armour that goes on the outside of the cable to protect it near shorelines: https://plus.google.com/+UrsH%C3%B6lzle/posts/Gwz3TFyvCAf?pi...

Isn't this a violation of the DMCA's anti-circumvention section? This seems to be explicitly describing how to circumvent protection measures for a copyrighted work.

200 years ago, how would you validate his claim? You would have to have a more accurate time reference, and I'm not sure exactly what that would be.
