    PCSPECIALIST National Archives anyone?

    Does anyone by any chance ever visit the National Archives at Kew? I have a real need to establish the actual movements of a Royal Navy survey ship called HMS Spitfire between May 1851 and May 1853 by checking the ship's log books. I have the reference numbers of all the relevant log books and...

    PCSPECIALIST 'esports' in the Olymnpics?

    Intel is apparently talking to the IOC about making 'esports' an event (or events) at a future Olympic Games. I assume this means gaming(?) and as a non-gamer I'm intrugued to know how this would work. So asume you're in charge of 'esports' at the Olympics, how would you implement and organise...

    PCSPECIALIST Why?

    http://news.sky.com/story/laptop-infected-with-worlds-most-dangerous-malware-sells-for-1631m-11730084 Surely you could just pick up a Win XP laptop for a few quid and leave it connected to the Internet for a few weeks. You'd get pretty much the same result and save well over 900 thousand pounds....

    PCSPECIALIST All Firefox extensions disabled?

    If you noticed your Firefox extensions were suddenly disabled this morning don't panic. It's a Mozilla certificate problem. They're on it. See https://www.zdnet.com/article/firefox-add-ons-disabled-en-masse-after-mozilla-certificate-issue/(/URL]

    PCSPECIALIST Time spent gaming

    I don't game, as most of the regulars here already know, I'm also past pensionable age, something else most regulars know too. That means that I have never been into the gaming culture, although I do understand the excitement and the attraction. What led me to post this was this comment in...

    PCSPECIALIST Foiled by a font

    A couple involved in bankruptcy proceedings in Canada tried to exclude two properties they owned claiming they were held in trust for their children. The court became suspicious about the two trust documents and called in a 'font detective'. He found that one document, supposedly written in...

    PCSPECIALIST 'It spoke to me'!

    There is a poster on a sailing forum to which I belong who is saying that a relative of his is being forced to change their password at Windows login and that the PC 'spoke to her'. I've never heard of Windows speaking at login and my first thought is malware, but has anyone else on here come...

    PCSPECIALIST YAIF (Yet another Intel flaw)...

    This one's called PotSmash and it's an Intel hyperthreading issue that potentially allows one thread on a mulithreaded core to learn information about the other thread on the same core. The good news for us home users is that the malware would have to get on our PCs first in order to exploit the...

    PCSPECIALIST Creating a 3D model from a DWG file

    I have a .dwg file produced by some unknown CAD software that is a contour map of the below-water area of a deep lake. The base data comes from a detailed underwater survey of the lake. I'm able to visualise the structure of the lake by looking at the contours on the .dwg file, but many others...

    https://www.prnewswire.com/news-releases/ibm-to-acquire-red-hat-completely-changing-the-cloud-landscape-and-becoming-worlds-1-hybrid-cloud-provider-300739142.html This makes perfect sense for IBM. We were running Linux on IBM mainframes when I was still working in the industry (I retired in...

    PCSPECIALIST Installing Windows store apps without using the store

    I'm pretty sure the answer to this is no, that's what my research suggests anyway. Here's the situation.... I currently have the ClassicFM Windows store app installed in my Windows 10 1803 system (my wife likes ClassicFM on all day). For reasons not at all clear the ClassicFM app is no longer...

    PCSPECIALIST UPS sizing

    This isn't at all scientific but it might help those considering a UPS (Uninterruptible Power Supply).... Here in Crete we get the odd power flick and even a full power cut from time to time and so several months ago I decided to invest in a cheap UPS. All I wanted it to do was to hold up the...

    PCSPECIALIST Managing Device Drivers

    Driver management is an aspect of Windows support that seems to cause a fair few problems. That may be because the function and operation of drivers is not well understood, or because driver support seems to be some sort of 'dark art'. Driver problems are the most common cause of BSODs, yet a...

    PCSPECIALIST Using The Event Viewer (and Reliability Monitor)

    Windows logs everything, and I really do mean everything, the volume of log records produced on a normally running Windows system is monumental. Most of them simply tell you that some ordinary (and perfectly normal) event has occurred. For example, when the user logs on a log record it written...

    PCSPECIALIST Using the Performance Monitor

    The Windows Performance Monitor is an incredibly useful tool and yet few users even know that it exists. As the name suggests the Performance Monitor (or perfmon for short) reports on your system's performance, but the detail that can be produced varies from tracking a single variable (like %...

    Open Task Manager and click the Details tab. Click the Name column to sort by name and then scroll down to find a process called 'svchost.exe'. How many svchost.exe processes do you have?

    PCSPECIALIST CPU Management - and why you shouldn't

    There are only two Windows controls available to the user that affect application CPU performance, Base Priority and CPU Affinity, and using either of them is more likely to make performance worse rather than better. It is surprisingly easy with these controls to make your whole system sluggish...

    PCSPECIALIST SuperFetch (and Prefetch)

    SuperFetch has generated controversy ever since it first appeared in Windows Vista. If you do a web search for 'Superfetch' today you'll see no end of posts with dire warnings to turn it off or your disk will explode and your PC will melt. What is this thing called SuperFetch then, what does...

    PCSPECIALIST The Page File, do I need one?

    Following the 'Understanding RAM' post I've received a PM about the page file, how big to make it, where to put it, and whether you even need one at all. Here's my views on the page file then.... From the 'Understanding RAM' posts you'll know already that virtual memory pages can reside either...

    PCSPECIALIST Understanding RAM management and use

    Most experienced users know that RAM is where program code and data are stored on which the CPUs are currently operating. It's important to appreciate that the CPUs can only operate on program code and data that is already in RAM - any program code or data that is not in RAM is effectively...
