Tesla Autopilot: BigData

Auto-mobiles are becoming more "auto-matic"

Google's Got Less Self-Driving Data Than Tesla, But It's Better | Inverse

"With 70,000 Autopilot-enabled vehicles on the road, Tesla gathers a million miles of driving data on people and autonomy every 10 hours. In all, around Autopilot has guided some 100 million miles and gathered data on 780 million human driven miles.

That means that Tesla gathers the same amount of driving data every day as Google’s autonomous program has gathered since it started in 2009."

ideas: Touchscreen as Keyboard (MacBook)

Apple's new MacBook Pro set to have OLED touchscreen above the keyboard | Daily Mail Online
"Apple is expected to unveil a radical redesign of its MacBook Pro laptops with a new touchscreen above the keyboard. The OLED screen would allow users to create their own custom keys for each app.
Apple was working on an even more radical touchscreen design that would replace a keyboard entirely.  Apple's keyboards may be getting thinner, but someday, the technology could be scrapped entirely. A patent filed by Apple today shows a laptop similar to a MacBook that features a flat touch surface where a keyboard would normally be. The invention, dubbed a 'configurable, force-sensitive input structure for an electronic device,' looks similar to its 'Force Touch' trackpads."
A patent filed by Apple today shows a laptop similar to a MacBook that features a flat touch surface where a keyboard would normally be locatedThe patent claims 'micro-perforations' in the casing could light up to give the user an outline to where keys are on the flat keyboard (left). The right image shows how the keyboard might look from behind
"The patent claims 'micro-perforations' in the casing could light up to give the user an outline to where keys are on the flat keyboard"

One nice advantage of "virtual keyboard" is ability to change keys to layout for more efficient typing, such as The Dvorak Keyboard, easy to convert to non-English languages, or to utilize "keys" as custom function keys for apps. Plus, such "keyboard" would be easier to keep clean.

A similar system could be assembled from ordinary tablets: i.e. just take two iPads and use one as a "virtual keyboard & touchpad" app for another, or for a computer. 
Same combination can be done by two phones placed in one case with a hinge (see below)

Still, many people may take long time to re-adjust. USA is still using "imperial" measures, not metric system, and everybody is still using plain email for most of communication... Change takes times... 

In my view, a better "evolutionary" option would be to replace laptop's touchpad with a touchscreen with full width of the laptop. That way it can serve its "classic" touchpad purpose, and as needed it can be used as an auxiliary display as well as a virtual keyboard, still preserving "classic" keyboard above. Evolution is better than revolution. 

By the way, there was already a device with two touchscreens (from 2010):

book: The Marshmallow Test

a very interesting presentation and book!

a sidenote: Long Now foundation made all videos public/free.
Before, that was available only for members.
After making videos free, number of paid members has increased!
Another "proof" of "doing well by doing good"

Walter Mischel: The Marshmallow Test: Mastering Self-Control - The Long Now

"Can “delay ability” be trained? Mischel thinks it can, if we understand how our mind works.
He and colleagues postulated a “Hot System” and a “Cool System” in the brain. (They are similar to Daniel Kahneman’s “System 1” and “System 2” in his book Thinking Fast and Slow.) 

  • The Hot System (Go!) is: emotional, simple, reflexive, fast, and centered in the amygdala. It develops early in the child and is exacerbated by stress. 
  • The Cool System (Know), on the other hand, is: cognitive rather than emotional, complex, reflective, slow, and centered in the frontal lobes and hippocampus. It develops later in the child and is made weaker by stress. 
In the Hot System the stimulus controls us; in the Cool System we control the stimulus.

You can chill a hot object of desire by representing it to yourself in Cool, abstract terms. 
Don’t think of the marshmallow as yummy and chewy; imagine it as round and white like a cotton ball. One little girl became patient by pretending she was looking at a picture of a marshmallow 
and “put a frame around it” in her head. “You can’t eat a picture,she explained. ...
If you don’t know how to delay gratification,you don’t have a choice.
If you do know how, you have a choice.”

security: Just Enough Administration (JEA)

podcast interview: Just Enough Admin and Windows Server 2016 with Jeffrey Snover - RunAsRadio

"How much administration do you need? Richard chats with Tech Fellow and Father-of-PowerShell Jeffrey Snover about Just Enough Administration (JEA). The goal of JEA is to get administrators to stop living in admin accounts, to operate day-to-day with regular domain accounts and only escalate up to admin for a specific task, typically written in PowerShell. Jeffrey talks about creating a "break glass in emergency" account that is the superadmin, only to be used when there's no other way to do something. This account should be heavily logged and scrutinized, so that root cause analysis can extract the needs for the event and create more automation and security granularity around it. JEA works on Server 2008R2 and above, and will be built into Server 2016!"

Soon We Won’t Program Computers. We’ll Train Them Like Dogs | WIRED
"Over the past several years, the biggest tech companies in Silicon Valley have aggressively pursued an approach to computing called machine learning. In traditional programming, an engineer writes explicit, step-by-step instructions for the computer to follow. With machine learning, programmers don’t encode computers with instructions. They train them.
Just as Newtonian physics wasn’t obviated by quantum mechanics,
code will remain a powerful tool set to explore the world."

Lambda Architecture and alternatives @LinkedIn

Questioning the Lambda Architecture - O'Reilly Media
"Jay Kreps is a Principal Staff Engineer at LinkedIn where he is the lead architect for online data infrastructure. He is among the original authors of several open source projects including a distributed key-value store called Project Voldemort, a messaging system called Kafka, and a stream processing system called Samza."
"These days, my advice is to use a batch processing framework like MapReduce if you aren’t latency sensitive, and use a stream processing framework if you are, but not to try to do both at the same time unless you absolutely must.
why can’t the stream processing system just be improved to handle the full problem set in its target domain? Why do you need to glue on another system? Why can’t you do both real-time processing and also handle the reprocessing when code changes? Stream processing systems already have a notion of parallelism; why not just handle reprocessing by increasing the parallelism and replaying history very, very fast?"

EXCLUSIVE: Tesla Model S, 3 and X at Gigafactory 1! – Motor Trend Presents - YouTube

AI IoT on a USB Key

Artificial intelligence now fits inside a USB stick

"The Fathom contains the Myriad 2 MA2450 VPU paired with 512MB of LPDDR3 RAM. The Myriad 2 is the chip found in the previously mentioned DJI and FLIR products. It's able to handle many processes simultaneously, which is exactly what neural networks call for. Because it's specifically designed for this -- its architecture is very different from the GPUs and CPUs that typically handle processing -- it offers a lot of grunt without requiring much power. It can handle up to 150 gigaFLOPS (150 billion floating-operations per second) while consuming no more than 1.2 watts.
Unlike Tegra's solutions for deep learning, the Fathom isn't a standalone system. The idea is you plug it into the USB 3.0 port of any system running Linux to get a "20-30x performance improvement in neural compute.
There's no firm price yet, but we're told it'll be less than $100."

data: HDD reliability

Who makes the most reliable hard drives? (updated) | ExtremeTech
"Backblaze ... buys whatever drive offers the most competitive dollar-per-gigabyte ratio, with reliability being a secondary factor
As of the end of December 2014, Backblaze had 15,528 Seagate drives, 22,902 Hitachi drives, 1,174 Western Digital drives, and 47 Toshiba drives. These drives are not all the same age — some are several years old, while many were installed in the past year, including thousands of brand new 4TB and even a few 6TB models.
Hitachi drives are by far the most reliable. Even though many of Backblaze’s Hitachi drives are several years old, they only have an annual failure rate of 2% or so on average. And the latest HGST drives have a failure rate of just 1.4%. The “annual failure rate” is the chance of a drive dying within a 12-month period.

"CSSX is not only about writing vanilla CSS in JavaScript. Even though you get this the main idea here is to have a good API for managing styles. CSSX doesn't inline styles so you keep your markup clean. It works directly with injected stylesheets. Here is a short example:"
function setStyles (fontSize, margin) {
  return <style>
    body {
      font-size: {{ fontSize }}px;
      line-height: {{ fontSize * 1.2 }}px;

var sheet = cssx();
