Japan reverses course on post-Fukushima nuclear ban


Reuse of old Reactor mechanicals

We here in the NYC are ust shut down two sites dur to age of the reactor containments. I have not heard of the generators, turbines, etc being scrapped. wonder iff new reactors were built, could they be connected up to these parts and used to generate power. The old reactors could be left until they could be safely removed and we would still have power. Anybody ever think of this ?

World record for strongest steady magnetic field 'broken' by Chinese team



Anybody notice that the two lines on the graph are exactly similar, and the bigger just looks like it was shifted up

'I wonder what this cable does': How to tell thicknet from a thickhead


Ah, the fun 70's

I worked for a well known computer company as on-site tech support in a VERY well known airline main office. This office did all the ticket requests for the whole world (I think). The net was spread over 4 floors and was thicknet with delay boxes (If I ever get hold of the guy who designed it ....). Problem was if the connection went down, (TThere was 6 separate lines), and you had to start on the end of the dead loop. Each line went in and out over the floors in no particular order.

I lost weight (Thanks, I needed the help) in my first three months going floor to floor running up stairs, down corridors, completely around the floor to othet departments, etc.

After 3 months I had the new working, knew the layout better, and had everything in hand. Until they decided to mod tghe server beast. That's when I got out. I was to be on 24/7 call with no extra pay.

Miss those days. The big city I worked in had a lot of small stores in the area, and plenty of parts places.

This data center will be Europe’s first with hydrogen backup power


Minor Side Effect

There is just one thing I can think of that may be a problem.

Let's call it "The Hindenburg Effect". Mind the leaks now !

When everyone else is on vacation, it's time to whip out the tiny screwdrivers


Tech tip

Jeez, for an old hand tech you have missed the easy out. Buy a plastic weekly pill case. Seven places to put small screws, a snap cover to keep them in, and an easy to move (if you have to) single piece.

As an old (and I mean from Apple II days), I found that that screw probably belongs somewhere near the edge of the battery. Just forget it, and add it to your collections of small screws, in case you ever need one. (In 15 years of Macs, every so often one goes AWOL. Reach for your extra screws and odds are you'll find one in there.

There was a crooked man who bought a crooked M1 iMac, and we presume they lived together in a little crooked house


As a long time Mac Tech, I can say that if you had taken it to our shop, under warranty, it'd been fixed ASAP. Unless the swivel mount is not mounted right, you get crooked display and the thing has a tendency to not stay in the position you wan it in.

Easy fix, so long as you are VERY careful with the screen. Having cracked a few before I learned the method, it ain't a user fix.

Facebook's new hookup: A pair of submarine cables to link North America, Indonesia, Singapore



You are right, it is laying a cable, but it is ,also, building the on-shore buildings, etc to make the thing work. Otherwise, some very pricey glass on the ocean floor. What would environmentalists say ?

Apple iOS 14.5 will hide Safari users' IP addresses from Google's Safe Browsing


OOPS....Apple is running OS 10.4.6

You guys in Britain are a bit behind the times. Apple released 10.4.6 a bit ago. BUT notice it only works on Safari, and most users have gone to a better browser. Apple should get Safari to work better. Been a long time since Safari worked correctly on some of my banking sites.

Stop asking for Amazon, Google and Microsoft cloud with 'no justification': US Library of Congress told to drop its 'brand-name'-tastic RFP


Re: Seems like school got dismissed early!

Isn't it amazing how everything is pinned to Trump, even if he had nothing to do with it ?

Maybe the mud will stick to the wall if you throw enough of it. I doubt the Donald had anything to do with the RFP.

Apple: Don't close MacBooks with a webcam cover on, you might damage the display


Interesting note

Apple used to send brown plastic tape to close the box of parts being returned. They work extremely well for covering the camera. Free, and always extra strips in the box. Used them in multiple customers who had a "security" problem in their workplace. As above, I don't know an app to turn on the camera remotely (probably because I haven't looked.

Breaker, breaker. Apple's iOS 12.4 update breaks jailbreak break, un-breaks the break. 10-4


Nothing new here

I worked on mainframes in the bad old days. A programmer wrote code that if the tape reel was full, it rewound the reel and erased all the data on ot. As expected, it caused consternation and was promptly "fixed" i.e. it was bypassed. After about two months, a patched version of the software was installed. You guessed it, it re enabled the old bug. Ah, the days when you got to meet the VP of engineering from Boston, who promptly said we did it somehow.

Customer fessed up after a day, but the chewing lasted a long time.

Wombats literally sh!t bricks – and now boffins reckon they know how


Re: Wombats shit bricks?

Sounds like a good idea. Then get Professor Rincewind to catch some of the little beggars.

I ship you knot: 2,400-year-old Greek trading vessel found intact at bottom of Black Sea


Ships sink when they their floatation ability is compromised. Perhaps they were overloaded and their freeboard got compromised ( gunnels under water). Weight of load sinks ship, perhaps some of it floats off, but the rest (non-floating) takes it down to the bottom.



Re: Classics

And the military equivalent of RTFM, RTFMS. Read the F****** Manual, SIR. Used when officer is not aware of certain acronyms. There are a few of these around.

Casting the anchor

Let's go back to when men first started sailing.

Back then, anchors were rocks with lines wrapped around them to hold the boat in place. They later evolved to rocks with a hole in it for making sure the rope didn't slip.

These were carried on deck, and when you went to use them you threw them over the side. You would want to throw (or cast) them over the side so as to not have the rock hit the side of the ship and damage it. Hence, casing anchor.

The first fluked anchor stopped the rocks and were hung over the side at the cathead.

Fun looking that up.

Enjoy, my British cousins
