Low-power chips are secret sauce behind long-life wearables

Because if you have AF (which is totally non-fatal), the docs are interested in what the ECG looks like whenever anything changes. I have occasional paroxysmal AF, and am just off to Google this kit...

An urban myth, eh? Presumably the picture is a fake? At least sixteen V-1s were destroyed this way, says https://en.wikipedia.org/wiki/V-1_flying_bomb#Interceptors. And I've talked to a bloke who, as a youngster, saw it done...

Re: Virgin works like a charm

What He Says. Put the Virgin 'router' straight into modem mode, connect to OpenWrt router, check line quality, fit (or remove) attenuators as required, chose Google/Quad9/Quad1 or any other public resolver for your DNS, and you'll be right.

That's my setup. I have a lot of folk in my area whinging over their VM connection on FB, and I've been rock stable for months, modulo one few hour outage caused (I think) by them rolling my DHCP lease.

Never mind Brexit. UK must fling more £billions at nuke subs, say MPs

Military expenditure seems a bit of a slippery number. SIPRI has France: $57.8bn, UK: $47.2bn, Germany: $44.3bn, Italy $29.2bn. So, is the UK is the military giant that dwarfs the rest of the EU? And as Brexit tanks the pound and the rest of the economy into the ground, we'll continue to go backwards militarily. Except in our imaginations. Cue yet more WWII docos.

Good news, bad news, weird news – it's the week in networking

Re: Oh, great: civil aviation wants to route messages over the Internet Protocol

Even worse, the end-to-end network that leads from ATC centre to VHF uplink to aircraft has no end to end error detection. Individual links, yes, but no way to spot corruption in the routers. I'm glad to see the IETF process being used here; less likely that that sort of networking 101 error will get through.

Re: Obvious need for..

So, old routers need to handle particular IPv4 packets in a special way. So you need to update them. And how exactly does the catchall system magically deliver packets half your network doesn't recognise?

BanburyBill

Re: Obvious need for..

OK, so explain to me. In detail. How do you increase the size of an IPv4 address *without* changing IPv4 packet structure in a way that will require updating the software (and very possibly hardware) on every router on the planet? Hint: extending the header, or changing field usage therein fails that test.

The designers of IPv6 weren't (and aren't) idiots, and they weren't (as often suggested) detached academics either, unless you think the likes of Cisco, Google, Nokia and Ericsson are detached academe.

Peace pays dividend for OpenWRT as 'baseline' release lands on servers

IPv6? Hang fire for now...

OpenWRT is Very Excellent. But this is a .0, and yes, 18.06.0 has fallen foul of a kernel bug on some platforms - https://bugs.openwrt.org/index.php?do=details&task_id=1541. For me this is screwing up IPv6 between wired and wireless hosts in my network. I'm an ar71xx, so on 4.9.111. Many other targets are on 4.14.52, and so are unaffected.

Re: intelligible ATC

ICAO Phraseology (which is the formulaic construction) does help, but still leaves space for misunderstanding especially when accents are involved. But it isn't used in the US. An ATC controller trainer once advised me that one should prefer flying to left pond with native English-speaking flight crew for that reason.

ATC digital messages are CPDLC, not ACARS.

One hopes the Grate Branes of the Brixiteers will be able to distinguish between the EU and EuroControl. The latter is larger, and predates the former.

Re: So NBNCo ...

Plus ca change. In the early days of the Overland Telegraph to Darwin (~1870), they kept getting line breaks because the local Aboriginal people found that the ceramic insulators made excellent sharp edges when broken, so climbed the poles and made off with them. Chief Engineer Charles Todd (the town of Alice is named after his wife) deflected this by ordering old broken insulators be left scattered around the poles after construction and maintenance.

Re: What?

Microsofties and their shills do have some really weird ideas. God knows where they get 'em. I've been using Linux since '92 and I don't think I've ever recompiled user-space software on Linux because of a kernel update.

QUIC is already fully open and will be turned into an RFC when iteration slows down. Meanwhile Google are working with IETF on it. Judging by the session on QUIC at the last IETF at which I lurked at the back, the IETF have no problems with the openness.

Some grist here for the Goldacre mill, methinks.

I had some green beer once in Chicago on St Paddys's day. If anything, green food colouring made the (non-craft) beer slightly more interesting.
