Ummm, you mean Hunter, not Hawk?

Because bl.uk started off many moons ago as the JANET NRS name UK.BL, back in the day when organisations that were considered to be neither commercial (UK.CO...) nor academic (UK.AC...) simply got NRS names of the form UK.<name>.
Of course this was before org.uk or gov.uk (or even their short-lived predecessors orgn.uk or govt.uk) were invented...
What's the point of being able to attach a payload of 64k of arbitrary data to a heartbeat message anyway?
What's wrong with a simple sequence number?
Did they think the case where the other end was sufficiently functional to interpret and respond to a protocol message, but somehow incapable of copying a block of memory correctly was worth detecting?
Did this Request for Comments actually get any comments?
Great article, some interesting new stuff there, but a couple of minor errors: all QLs had the BS6312 (BT phone-plug) type sockets for the RS232 ports, except for the ones built by Samsung, which were only for export markets; and the ultimate CST Thor model was the Thor XVI which was a complete hardware redesign using an MC68000 (the Thor 20 had some kind of daughterboard on the QL motherboard for its MC68020 CPU).
Rick Dickinson (Clive Sinclair's equivalent of Jony Ive) came up with a design for a second-generation Sinclair QL in the mid-80s based around vertical air flow, complete with a "chimney" on top, that never saw the light of day. You can see a photo of a mock-up of it in this interview.
...and the Russians: see the Strait of Juan de Fuca laser incident.
Well, it took 7 seconds for a Microdrive cartridge tape loop to complete one pass, so loading a game from Microdrive shouldn't take much longer than that (unless it was a dodgy cartridge and some sectors needed more than one attempt to read). A lot faster than cassette, and probably quite comparable to a floppy disk.
One of my most satisfying bits of hackery I did on my QL was reducing the number of cartridges required to load The Pawn from three (two "working copy" carts plus one original for copy protection) to one - I worked out I could squeeze the the contents of two cartridges onto one, which I formatted with the same magic ID code as the original cart using some Microdrive "utility" software. Playing the game was almost as much fun...
Must power up my QL again and see if the Microdrives still work - they did about 4 years ago...
I think notionally the MS-DOS BIOS was split between the ROM BIOS (which would be customised to the particular hardware configuration of the PC) and IO.SYS (or IBMBIO.COM if you had PC-DOS) which was intended to be generic. The term "BIOS" is now so closely associated with boot firmware that we forget it used to be an integral part of a PC's native OS....
The Alpha architecture was intended to have a lifespan of 25 years. Whether it was capable of that is moot, since it was canned after 12, but there were at least two more generations under development when that happened.
Oh and OpenVMS, Linux and Windows already ran on Alpha platforms, as did Tru64 UNIX. Not a bad "porting platform" (whatever that is exactly...).
Huh? There was no IPv1,2 or 3 - IPv4 was numbered to match the corresponding TCP protocol version (RFC793). TCP actually predated IP, (see RFC675) and hence was in its fourth version at the time.
And IPv5 didn't really exist either - version 5 was used to distinguish IEN-119 ST stream protocol packets from IP packets. ST was not intended as a replacement for IPv4.
I think someone might be getting mixed up with the old Linux kernel version numbering scheme...?
10 years?
Would you call a B-52 a combat aircraft? They're all about 50 years old now, and the USAF are planning to keep them in service until at least 2040...
Even the RAF's Tornado GR4s are around 30 years old now...
So the A4 (or PQ34 as VW Group call it now) platform was "dull and wretched", but the A5 (or PQ35) platform is "a country mile better". In terms of dynamics, the main difference between the two was the rear suspension - torsion beam on the former, multi-link on the latter. Interestingly, the New New Beetle only gets the PQ35 rear suspension on the 2.0 TSI model. What do the lesser variants have? You guessed it, torsion beam!
As for the "daft rear spoiler", I don't think that back end is going to generate much downforce by itself, so I think I'd rather have one, thanks. Anybody remember the hasty recall of the original, spoiler-less Audi TT?
About the submarines: "Journalist and historian Professor Peter Hennessy claimed in his book, Secret State: Whitehall and the cold war 1945 to 1970, that he had been reliably informed that the test a commander of a British nuclear-missile submarine was to use to determine whether the UK has been the target of a nuclear attack (in which case he had sealed orders which may authorise him to fire his nuclear missiles in retaliation), was to listen for the broadcast of Today on Radio 4's frequencies."

I presume LW would be easier to pick up from a random spot in the Earth's oceans than VHF...
Never having used Windows Phone or Windows 8, am I correct in guessing there is no colour coding to the background colour of the tiles, and the colours are in fact chosen in a random-and-pleasing manner? Seems like another violation of fundamental user interface principles if so...
I believe I made this comparison about four months ago.
(IIRC the ZX80 keyboard was thinner than the ZX81's so probably a better match).
This report on the Avro Canada Y-2 (complete with lots of lovely drawings) was released in 1998.
