Battery for Dell Studio 1537

Software based on XP is used to run the command suites of most of Blighty’s major warships, including the Type 23 frigate fleet and the newer Type 45 destroyers, the last of which entered service in 2013.HMS Queen Elizabeth will begin her sea trials in August 2016 that the MoD said will last until mid-2017, after which she will be officially handed over to the Royal Navy.Following this, the ship will go over to the East Coast USA for flight trials in 2018 for the F35b, but all her systems will be complete and operational in 2017, and be fully in service as the flagship vessel from 2020, the MoD said.On-Call Welcome again to On-Call, our Friday column in which readers tell their tales of being asked to get stuff done under awkward circumstances.This week, reader “WG” shared a tale from 2010, when a client asked for some very major changes to be made to an industrial system that had been left largely untouched for 25 years.WG and his colleagues tried to dissuade the client, because documentation of the system had somehow managed to disappear over the years. The folks that built the system were retired and scattered to the winds.“Everyone in the industry advised us not to touch a thing and to walk away from the job,” WG told us.

But then, just a couple of weeks before Christmas came the request to do the job, before Christmas of course.“A less than really sharp manager agreed,” which meant that in the days before December 23rd WG “was going flat out trying to get my head round a program written by a novice programmer for an ancient logic controller in a horribly arcane language.”“Then on Christmas Eve myself and a colleague went on site to do the installation. By the way, did I mention that we couldn’t do any preliminary tests because they wouldn’t shut down the system until the night before?”“Initially we couldn’t get the laptop to talk to the old controller. It took us several hours to work out that not only was the connecting cable non-standard wiring, but so was the communications. Eventually we got the software on, and started making cautious tests – we hadn’t wired the new valve in at this point just in case there were problems.”

“First, the control sequence was not the same as what we’d been told, so that involved rewriting the program on-site to take this into account.”“Next, the original programmer liked to do ‘clever’ tricks with his programs. These always come back to bite you years later – and indeed we were seriously puzzled as to why variables were apparently changing themselves and screwing up our corrections.”WG and his colleague “realised the guy had discovered a way of bulk updating large blocks of data, which he’d proceeded to use enthusiastically, blissfully unaware that this also corrupted variables in the ‘gaps’ that he wasn’t using but we were trying to!”“After this was sorted we connected up the new valve, which had been pre-wired for us, only to discover that the ‘telltale’ that was supposed to send back a message to tell us which way the valve was positioned wasn’t changing, so we went to examine the valve itself.”Inspecting the valve mean climbing narrow metal stairs and gantries.“My colleague got there first,” WG recalls, “and came out with a burst of the most interesting invective. You see, this valve was driven by compressed air, and our electronics just supplied a trigger. This normally works fine, but you do actually have to pipe in an air supply! We then had our only short break while the factory maintenance crew frantically rigged up a temporary air line.”

Before long the valve was switching over correctly. But WG and his mate wanted to double-check to make sure all was well and when they did, found that the main plumbing had been done in reverse.“Our first thought was to just change the software so the ‘off’ state of the valve was reversed, only we were quickly informed that when unpowered it had to be in the open position.”The maintenance crew climbed the gantries again and, amid “much banging and swearing” went over everything in as much detail as possible.”“We weren’t happy that the valve common was shared with the signal common, but weren’t going to try to re-run over 70 ft of cable woven into the factory structure, so put filters on the PLC inputs and hoped.”Job done! Or so WG thought until control system’s monitor died. WG thinks all the switching things off and on did for it, and fair enough after 25 years’ service. One trip down into the offices to find an unused monitor later, and WG thought it was finally time to head home for some egg nogg.But first, a final test to make sure the night’s work hadn’t caused a problem elsewhere in the factory.

A main divert valve stuck but that had nothing to do with WG’s work. But he had to hang around to make sure all was well.“We started at 8:30AM and worked through until 10:00PM without stopping, except the one time for a cup of tea and a snack (supplied by considerate shop-floor staff).WG made it home for Christmas, albeit without knowing if his work had done the trick because the client wouldn’t run the whole system until the new year. His clients, however, declared themselves happy. Which was enough at the time!Have you been called out to work over the festive season? We’ll be running On-Call stories every day next week, so if you’ve a Christmas cracker to share, send me a Christmas card. Stolen medical information is a prevalent problem across multiple industries, according to a new study by Verizon.The issue is compounded because many organisations outside of the healthcare sector do not even realise they even hold this type of data.Common sources of protected health information are employee records (including workers’ compensation claims) or information for health programs. These repositories are frequently poorly protected.Medical data loss is not just a problem for the healthcare. According to Verizon, 90 per cent of all industries have suffered a data breach that resulted in the loss of medical data, including: retail, finance, mining and educational sectors, amongst others.

Verizon’s researchers analysed 931 incidents of confirmed protected health information breaches involving more than 392 million records. The global study covered 25 countries across North America, Europe and the Asia-Pacific region.One in five health record breaches involved privilege misuse. Staff not infrequently abused their privileges in order snoop and look at medical records health on the same local area network or on a weakly secure database server on the corporate intranet.Loss of unencrypted devices is a major problem for the healthcare industry itself. Around a third (31.3 per cent) of incidents where human error was involved in one way or another in data breaches were down to lost devices.The one positive trend in this area over the last five years is that it’s taking less time for organisations to realise they have a problem. Even so only 31 per cent of incidents are found within days: 31.25 per cent took months and 18.75 per cent took years to find.Verizon’s 2015 Protected Health Information Data Breach Report was compiled by the same team that puts together the firm’s Data Breach Investigation Report, a benchmark annual study of data breaches.The health information reports focuses on the problem of medical data loss, from how it is disclosed, to who is causing it and what can be done to combat it.
