Underscore indicates Ludicrous Credit: Auto Evolution
Tesla famously claims 2.5 sec 0-60 mph for a TeslaModel S P100D in Ludicrous mode – is that accurate? Other measures – 0-100 mph? – ¼ mile?
Drag Times managed to score one for a very quick run. Somewhat surprisingly, it was fitted with 19" wheels, rather than the usual performance option – 21".

Uber self driving Ford Fusion – in addition to the obvious array of sensors on the roof, notice the much smaller sensor just ahead of the rear tail light cluster Credit: PC World
While much of the publicity goes to Tesla’s Autopilot, other manufacturers are making a big autonomous vehicle effort too.1,2 Case in point, Uber has recently introduced its autonomous cars to limited service: a 12-square-mile part of downtown Pittsburgh, & offered only to select Uber clients. Two Uber staff are on board – one behind the wheel, ready to take over driving duties if necessary, & the other monitoring the computer system.

Linus Torvalds1,2 was a student at the University of Helsinki when this appeared on a mail list:
From: torvalds@klaava.Helsinki.FI (Linus Benedict Torvalds)
Newsgroups: comp.os.minix
Subject: What would you like to see most in minix?
Summary: small poll for my new operating system
Message-ID: <1991Aug25.205708.9541@klaava.Helsinki.FI>

Hello everybody out there using minix —
I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).
I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I’ll get something practical within a few months, and I’d like to know what features most people would want. Any suggestions are welcome, but I won’t promise I’ll implement them :-)
Linus (torv…@kruuna.helsinki.fi)
PS. Yes — it’s free of any minix code, and it has a multi-threaded fs. It is NOT protable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that’s all I have :-(.
Recently, the operating system that emerged from that casual announcement turned 25. In those years, 41,000 person-years of development effort (equivalent to about $5 billion in developer salary) has produced 115 million lines of code which largely powers the Internet (serving this page too), Android, Chrome OS & others.

Belkin Lightning Audio + Charge RockStar Credit: Belkin/Steve Garfield/Off On A Tangent
* from 10 October
So the iPhone 7 has no 3.5mm earphone socket.
Why? – the major parameter of smartphone design is skinny jeans compatibility – that means small & above all, slim. For the internals of a phone this means make everything smaller (nano SIM) or eliminate it altogether – what happened to the 3.5mm earphone socket in the iPhone 7.
One widely canvassed concern is that it is not possible to connect headphones, speakers, etc. to an iPhone 7 & charge at the same time. There was never any doubt that solutions would be quick to appear. First out of the gate is Belkin's Lightning Audio + Charge RockStar – although not until October.

20,000 BC – much of the Earth was still covered by the glaciers of the last ice age. Temperatures were cooler than today – around 5 Celsius degrees on average.
