> United, are your security people listening?
Nah, they are all stuck in a departures lounge somewhere on their way back from a conference because their flight was delayed/cancelled.
So...longer than an 8 hour wait at SFO before your flight to LHR is finally cancelled and you have to fly to Dulles and eventually arrive back home over one day late...and no you can't use our lounge while we dick around trying to work out how to get you home?
I refuse to fly United now .. all subsequent business flights have been with Virgin Atlantic.
This is not an HDS system; it's from HGST - totally different organisations.
These systems use Erasure Coding to scatter elements of the stored objects across multiple disks (or sites, if you have more than one system), and rebuild times are based on the time taken to reconstruct the elements stored on one disk.
There are boxes out in the field (previous generation ones) for which reliability data is available, plus there are the ones in the labs and development centres. Overall, it's possible to calculate reliability figures based on the MTBF/AFR and other parameters for individual components.
These systems don't use RAID. Check out 'Erasure Coding'
Exactly! The storage policies which determine how objects are stored, how many parts they are spread across on the disks and how many parts we can afford to lose (the 'safety') is customer configurable and determines the effective storage size.
/Currently sitting in a training course at HGST for this, so getting a kick etc...
It was the mid/late 1980s and we'd just installed a row of spanking-new IBM PC-AT computers (286 processor, no less) running a CAD application called Daisy on a *nix OS called Daisy-DNIX. In those days RAM was very expensive so not a lot was fitted and the systems swapped to disk constantly.
Everything was going swimmingly until some electronic-engineer-who-should-have-known-better fancied a brew-up and plugged his electric kettle into the end socket on a run of daisy-chained (heh!) extension leads. Of course, the fuse blew in the FIRST plug and all the computers went down.
The resulting mess caused by machines that were shut down incorrectly while busily swapping took a couple of days to sort out.
Those machines swapped so much that we were forever replacing busted disks.
Happy days. Have a read: https://en.wikipedia.org/wiki/Daisy_Systems
Just have to mention my Acorn System 1 from 1979; this was Acorn's first commercial computer. I received it about a year ago from someone who had it 'in a box under my desk somewhere'. The unit needed some TLC, but after a few PCB track repairs, a couple of replacement logic chips and some rework on the LED display ribbon cable it's up and working again - although I have to admit that I don't run it 24/7 and the display is not up to email or surfing the 'net.
You can see a pic of the unit here: http://forum.6502.org/viewtopic.php?f=12&t=3286&start=15
It's sitting on a pile of parts I have ordered so I can make a replica (when I get round to it!)

Um..OK...you carry on there. We all went down the pub about 3 hours ago.

"The 77-page report dug up extra vulnerabilities in the once-popular encryption platform but say none are sufficient to undermine the jettisoned software."
"Sure, but then what do you do when this technology gets used out on the street or in shopping centres?"
Then it will be OK, because we will be reassured that, just like MAC address wifi tracking, it's being used to 'enhance our shopping experience'
I remember it well. I had a day job, but also worked on a freelance basis for PC User Magazine (RIP). I was sent 'something-or-other-utility' to review, only to discover that it needed Windows to run. I spoke to the editor; one quick phone call to Microsoft and a few days later, a stack of 5.25" floppies arrived containing Windows 1.0. Might still have them somewhere.

I had a similar experience with some of the computers at a cement factory in Wellingborough. They were pretty wrecked.
One of my engineers serviced a machine that came back from a local farm's milking shed. The machine needed a complete clean out and the floppy disk drive was replaced. The engineer wrote up the repair description as "Half a field removed from computer".
In the early 1990s, I turned up at a Ministry of Defence (MoD) site in the UK to load some software updates onto a Netware server. Having duly passed through all the security checks, I was led to a busy office that looked like it was last refurbished in the 1950s.. "It's in the corner..' I was told. After about half a minute of trying to locate aforementioned server, I asked for some guidance..."Oh, filing cabinet - bottom drawer.. I'll remove the padlock." The padlock came off and a solid steel strap that ran from top to bottom through all the handles was withdrawn like Excalibur from the stone. There it was - a Toshiba T3200 with orange plasma screen running Netware and hosting who-knows-what secrets on its hard disk. A hole had been cut out of the back of the cabinet to poke through the power and data cables. "Most secure server in the building, I was advised".
So I got to work, crouched down in front of the filing cabinet. About 10 minutes later, a phone started to ring in the next drawer up - a muted bell, it's ring deadened by something..a war surplus sock maybe!? "There's a phone ringing in here", I volunteered. "Oh,we don't answer that one", came the reply.
If the UK authorities adopted the same mindset and paid a visit to my spare room (aka 'workshop'), they'd find several Raspberry Bombs, Arduino-grenades and nano-grenades, ESP8266 IoT wifi remote detonators, antistatic bags full of I/O bombshields, trays of PIC Microbombs, Serial Flashbang RAM, 7-segment LED countdowntoarmageddon indicators, LCD bomb displays ('your bomb temperature is ...nDegC'), USB-Serial TTL bomb interfaces, a 1979 Acorn System 1 6502-trainer-cum-bomb, some old EPROMS (EBOMBS, more like, eh!), ultracapacitor detonators...
The other week, while browsing through a computer and electronics surplus warehouse (aka bomb factory), I even picked up what can only be described as a hardly-used Sinclair ZXeightybomb.
The dead giveaway is the storage drawers containg piezo sounders and LEDs, which I use to make sure that all of the IoT...er...bombs that I construct make a telltale bleeping sounds accompanied by blinkenlights to ensure that they can be easily spotted under vehicles and in the noisewheel compartments of passenger aircraft. Hell, I even have WIRE.
I'll get me coat and turn myself in right now.
Sure, I'm delighted with the next-day banana delivery service from Amazon Primate.
I have something to tell you...I...I...signed up for something on my computer...and...I ended up getting fucked by people I'd never met before...I couldn't help myself...the thought of something new and different was so attractive I just had to give it a go...but now I feel like I have given away my soul and my private affairs are being exposed for others to pick over...Oh darling, I have made a terrible mistake and I feel there's no going back...everything that was private is now in the hands of others.
Dearest, please don't tell me you signed up at Ashley Madison!??
Oh no, dear - I...I installed Windows 10.

Netware admins will know what I mean.
No, not *that* classic use of rm -rf, but..
The Financial Director where I worked a bazillion years ago needed to restore from tape the (b)ought ledger files to our SCO Unix box.
Unfortunately, he restored the files to the root of the server's disk, and rather than move them into place, he restored them again - correctly - and then issued rm -rf b* from the root folder.
Things were hunky dory for a few weeks until we rebooted the server during overnight routine maintenence and it didn't come up again.
One trip to the office later and I'd discovered that /boot was missing. Two hours pass and we were OK for the morning, but I had to wake up the MD to open the main office where the master tapes for the OS were stored in the safe.

Having just written a full JSON string parsing routine in bash, and then done the same in DOS BATCH to produce a pair of Linux and Windows plugins for Nagios that need no additional support libraries or installed tools or apps, I am getting a kick...
Yeah, I read El Reg reluctantly - I respect its pedigree and it does publish some good news/articles, but the puns (or poor attempts at puns) and stupid, random, CAPS in the headlines really take the shine off the overall experience; it's all totally unnecessary. I feel like I should wash my hands and sanitise the keyboard after a site visit.
>> The tiniest of the three, the Artik 1, is just 12mm square, which Samsung says makes it the industry's smallest IoT module.
Um, wouldn't that be something like an ESP8266-based module? The -09 variant is 10x10mm. Admittedly, it doesn't have a display output, but if you're an IoT sensor module why would you need that? The entire ESP8266-range does, however, have a full wifi stack and Tx/Rx module in silicon.
Don't get me wrong - Sammy can send me some free samples if they wish!
'sabout now the EPROMs (if any) start dropping the odd bit.

How about a barcode against every El-Reg article which we can scan with a smartphones to get an instant score of the amount of bullcrap in aforementioned article.
The IoT article would probably result in an integer overflow.

"Hitachi is now the reliable-drives arm of Western Digital"
Sorta, but Hitachi sold the business and it became HGST (a Western Digital Company) and it's totally nothing to do with Hitachi any more.
Also, WD and HGST's drive plants and designs are completely separate and can really be counted as two separate manufacturing entities.
My primary test servers are ADA and GRACE
I have a home Linux server running Serviio and we've been streaming to my son's PS3 since we bought it when it first came on the market - it sees Serviio as a regular UPNP/DLNA server. Never had an issue with it.
Not quite - The Arduino generation can cobble together a bit of code and do a fair amount of simple analogue and digital interfacing, but ask them to throw together a Wien bridge oscillator, whip up a sensor interface with an instrumentation amplifier, generate a sawtooth with a UJT, or calculate the resonant value of an LC tuned circuit and you'll often get a puzzled look, followed by a quick trip to ebay to see if there's a shield for that.
It's modular hacking and not pure electronics - not that there's anything wrong with that.
Hobbies are changing - but not quite changing *back*.
True - I have just bought 100 x 220 ohm 1/4W 5% resistors from another UK supplier for £1.30
Yes, I remember those vouchets. In 1981 the MD of Maplin personally arranged for a box of catalogues to be sent to me for sale on our Electronics Club stand at our school Summer fete.
Sadly the company is a shadow of its former self. How times and hobbies change.
So, I'll no longer face situations like when one Openreach 'engineer' stole our landline from up the pole to provision a new line for a neighbour and it took ten days for them to come and put me back online.
Now - about the FTTC that was slated to go live in our village in March this year....?

So which is it?
Grammar: How does it work?

PPS: No STUPID random caps in headline, so there's some hope.
..and these are the GANGSTERS that have to be referred to in CAPITALS - the real hard buggers.
Reminds me of my time working for a large UK veterinary group - one of our patient/client management apps couldn't work out birth dates or ages correctly - you'd register a new pet and enter the birth date given by the customer and the software would fill in the approximate age field (or you could fill in the approximate age and it would work out the rough birth date).
Trouble was, you'd enter something like 'Poochy'..born 9-12-2005 and according to the software, the poor dog would be something like 402 years old!
After some email correspondence with the support team, their conclusion was 'date handling is complex'.
It was never fixed. We eventually kicked out the system for a myriad of reasons.
1) Extra POINTS to be awarded to the student for apparently RANDOM words TYPED in capitals
2) Strained references to body parts, sexual innuendo or 'fourth form humour' to be considered for merit
3) Half point bonus for inclusion of the word MEELLION (MUST be in capitals)
This article will do as well as any other sooo...
It SEEMS that the fourth formers who edit El Reg as a social media project have got bored with STUFFING article titles with innuendo and have now COME ACROSS the CAPS KEY, which they seem all-too-keen to POKE in order to SLIDE BIG letters in the article titles wherever possible. On a Web page, this looks odd, but in an RSS feed reader it's just painful. I appreciate that El Reg is the red top of online tech journalism, but it wouldn't be too HARD to resist TEMPTATION and SLAP this annoying new trend before it EXPLODES to COVER every single word.
