Don't over-estimate how big those revivals are though. Vinyl only looks like it is selling in significant volume because no-one buys music on physical media any more. CD sales are way, way down in the last decade, as are music sales in general thanks to streaming.
I was surprised to see camera shops trying to make a comeback. There is a chain in the UK called Jessops, which had a pretty terrible reputation for being an over-priced hard-sell rip-off even back in the day. They all closed and a low grade celebrity businessman bought the name, and is trying to bring them back. But everything in there is still twice the price you can get it on online, and with online sales you have more consumer rights.
I'm not rich and I have an EV. In fact used ones are popular with people who can do the maths required to understand how cheap they are to own, like taxi/uber drivers. My old Leaf is an uber now.
It will be interesting when we get to the tipping point where it's actually a real pain to own an ICE vehicle in some places, due to lack of refuelling stations in the area.
Better than sexbots. Can you imagine when those things start getting hacked, demanding 0.5 BTC to release your genitals? And the inevitable manufacturer supplies spyware. Or when she won't give you a blowjob because her vaginal fluid tank is low and your subscription is about to expire.
And that's before she gets turned into a Russian propaganda outlet.

- 5% diagnosed with a mental illness. How many undiagnosed? If you don't have free high quality mental healthcare and a culture that finds mental health embarrassing and discourages males in particular from seeking help, you might well find that your diagnosis rate is low.
- 120,000 gun related killings, but 175,000 gun related suicides. Most suicides are the result of mental illness.
The difference is that computers are designed for innocent use, and often have features to prevent misuse. Guns are designed to kill things, and that's pretty much their only use.
We regulate things based on risk. Cars are medium risk, they can injure or kill but that's not their primary purpose and they have extensive features to make them safer. Even so, you need a licence and some mandatory training/testing to drive one. Interestingly the US has a very low bar for driving, in comparison to other developed nations.
What seems to have screwed this generally pretty successful system up is the US constitutional right to bare arms. Unfortunately it doesn't specify what kind of arms, but it does seem to recognize the need for some control and training with the "as part of a well organized militia" bit. Emphasis on "well organized", which I'm sure someone will interpret as "keeps at least 10,000 rounds neatly stacked in their basement".
XMOS do make some interesting parts, but they are all geared towards high performance. That's great some times, but when you need low power it's still impossible to beat 8 bit MCUs. Fortunately they are relatively easy to context switch on as well, since it's basically a few work registers and a stack pointer.
There is an additional cost to nuclear - the need for large amounts of excess capacity.
Nuclear isn't good for ramping up/down its output to follow load. It's also a huge single point of failure - Hinkley C is rated for 3.2GW, so a single emergency situation can instantly take that amount out of the grid. Thus you need significant amounts of power on standby to kick in quickly if something happens, or you face brown-outs and controlled black-outs.
Because solar is distributed and battery backed, single failures are much less severe. Batteries can easily vary their output in fractions of a second, as fast as the inverters can manage.
Most phones have NFC which can be used with a suitable token that also has USB for desktop use. Many phones have USB-C as well now, which you could plug the token in to.
It does proper context switches via a single function call, so no horrible spaghetti code. There are some down-sides, such as slightly higher stack use and needing to allocate enough stack to each task, but that's a fairly standard thing for embedded developers anyway.
The online mbed IDE is something of a deal-breaker for a lot of people. You are completely at their mercy, when they terminate the service all your projects and code will become useless. They can make any arbitrary changes they like and you have no way to reject them.
STM32 is just ARM, so you might as well just use whatever free ARM IDE you prefer. Eclipse and GCC work well.
One of the reasons why Atmel AVR is popular is that it's supported by free development tools. In fact Atmel ship GCC as their compiler in Atmel Studio.
If you want a high level environment with libraries to do all the complex stuff, ARM is a good bet. If you want something a bit lower level, a bit more raw, AVR is a good option and you don't need to rely on libraries.
Why would the chipset handle wifi packets when the wifi receiver is turned off? And even if it did, with the transmitter turned off how would the tracker ever know that it did? There is no energy going to the transmitter, no energy radiated.
Perhaps you are referring to some Apple devices where the off switch doesn't actually turn the wifi off, but most devices don't have that fault.
There used to be an issue where devices would broadcast the SSIDs of networks they knew about. That was to handle networks that didn't broadcast an SSID themselves, but it's mostly been deprecated and was one of the reasons that MAC address randomization was introduced.
Aside from TfL's apparent confusion of various technical terms, it looks likely that the salts could be recovered. MAC addresses are not random, they are assigned in blocks to manufacturers. Some devices do randomize them, but some don't and it appears that they use only one salt per day for every MAC address they hash.
You can assume that there will be a large number of devices running wifi chipset X and not randomizing. That gives you a way to check a salt for validity, i.e. if when combined with known MAC addresses from the ranges allocated to that manufacturer it produces a hash in the TfL dataset. And you can further narrow this down by taking your own device with a known MAC address onto the tube during the test.
It's probably fine... But their lack of technical clarity and secrecy about the scheme they used (for all we know the salts could have just been the date or something silly) isn't very encouraging. As a branch of government they should set the gold standard for this stuff.
I'm "planning" to fly to the moon next Tuesday, doesn't mean it will happen. And as China stopped approving new coal plants a year ago, the cancellation rate has increased dramatically.
Also, "700+" new coal plants would create a vast oversupply in China. It would be a huge crisis.
Also, all new nuclear plants in China have been cancelled, the only ones getting built are ones that were started before 2012.
You forgot to factor the massive subsidy that nuclear gets. Hinckley is guaranteed massive subsidies for life, while this wind farm is subsidy free.
Including subsidy the cost of Hinkly C is expected to be around £37bn, which is just under 6000 GBP per household. That's assuming it comes in on budget, which is unlikely to say the least.

I think that's more a testament to modern CDN technology that can handle sudden surges in traffic with ease.

That doesn't sound like Europe at all. Full range of weather to suit any taste, strong gun control and very low gun crime rates.
Can you imagine a bunch of people in the crowd firing randomly in panic?
I remember the old Fujitsu 4 bit parts. No C compiler of course, you had to use assembly and it was a right bigger. Good times.
I think it's to do with meta moderation. A lot of my posts get trolls modding them down, and it's 50/50 if the genuine mods win out.
My defence is living somewhere that is less dangerous so I don't need to defend myself from people with guns.
Guns aren't very good for self defence though, are they? Countries where people generally don't own or carry guns tend to be a lot safer.
I guess the points to consider are:
- 5% diagnosed with a mental illness. How many undiagnosed? If you don't have free high quality mental healthcare and a culture that finds mental health embarrassing and discourages males in particular from seeking help, you might well find that your diagnosis rate is low.

The cure is worse than the disease in America's case. There are three possible treatments:
1. Stronger controls on guns
2. Free, high quality mental healthcare
3. More guns
Number 3 is the least effective but also hated by fewer people than 1 or 2.

I wish they made a USB key with an emergency suicide feature. Even just a button which if pressed five times rapidly erased the keys.
Physical security is an increasing problem, especially at borders.
event loop driven mini-OS.
Ugh.... I hate those so much. Every function that runs for more than a millisecond becomes a giant, unwieldy state-machine and a nightmare to debug.
Here's an example of a proper, cooperative multitasking system: https://github.com/kuro68k/xmu...
It does proper context switches via a single function call, so no horrible spaghetti code. There are some down-sides, such as slightly higher stack use and needing to allocate enough stack to each task, but that's a fairly standard thing for embedded developers anyway.

TFA says "tonnes". Maybe we should just use gigagrammes for clarity.
You forgot to factor the massive subsidy that nuclear gets. Hinckley is guaranteed massive subsidies for life, while this wind farm is subsidy free.
Including subsidy the cost of Hinkly C is expected to be around £37bn, which is just under 6000 GBP per household. That's assuming it comes in on budget, which is unlikely to say the least.
