Security robot falls into pond after failing to spot stairs or water

Re: @Michael H.F. Wilkinson: Your thinking about it wrong...

I think throwing in the occasional "exterminate!", "exterminate!" would be useful or therapeutic.

HP Inc's rinky-dink ink stink: Unofficial cartridges, official refills spurned by printer DRM

First rule - don't go with HP - frustrating and expensive - they are not there to help you.

Config file wipe blunder caused deadly Airbus A400M crash – claim

Dave 42

Funny how Software – being “invisible” isn’t treated in the same way as stuff we can see – even by SW engineers. The config files are as critical to the aircraft as are the propellers. We can see the propellers “Oh, 3 props are missing, maybe we shouldn’t try a take off”. Are the config files there? Who knows? Let’s just go for it!

It’s the duty of the SW designers to make the critical items visible to the pilots – are the files there?, are they the ones you expect? – OK, next item on pre-flight checklist.

What's wrong? Several times in this Register article, space is simply spelled space - not the recognized convention here of SPAAAAACE. Do follow the style guide chaps.

Scientists skeptical of Lockheed Martin's truck-sized fusion reactor breakthrough boast

Re: Size

Well, 7x13 meters is pretty big - but it's the third dimension that they don't mention - it could be huge

Fukushima on Thursday: Prospects starting to look good

charter member - great unwashed

It must be pretty tough *sighing* all the time at the idiots that surround you - too bad that so many folks know more than you. But you might not have noticed.

Check the photos - reactor one is cut off nicely, Not reactor 3 or reactor 4 which has a nice hole low down. Plus reactor 3 blew things sky-high - not the nice "balloon explosion" of reactor 1.

mark 1 GE BWRs - noted to be a poor design, several of the GE engineers resigned in protest when it first went out. If it loses power - it blows - simple. And so does any stored fuel. Oh Well, they all have backups - like Fukushima. But then maybe only tsunamis cause total power loss.

And the hydrogen - yep, created when the zircaloy cladding burns (reducing the steam) - not a good thing (another great design feature). If this hydrogen production possiblity really was part of the reason for the empty buildings why were vents not designed in, instead of the (you imply) planned explosions. Plus why were the stored fuel assemblies stored high up in the buildings?

This article is a joke - right?

What's this guy's talk about spent rods gently heating???

over at the MIT site it's mentioned that each spent fuel assembly (even after weeks) produces about 4 Megawatts of residual energy (about 5000 HP) day in and day out, and this is enough to boil off about 40 tons a water a day - no wonder the pools are dry. And that's just one assembly!

Sad that if the GE mark 1 BWRs lose power (for whatever reason) they blow up - simple. Plus any stored fuel goes up too. Oh well , all these plants have good backups. Like Fukushima.

Also for those knowing commentators (like our friend here) who say it's over-reacting to call Fukushima Chernobyl-like. Well, yes... Chernobyl didn't have tons and tons of spent fuel stored above its reactors in open tanks, chernobyl was only 1 reactor melting down, not 4 melting down, Chernobyl was in a deserted area, not next to 26 million people and the core of a good percentage of the world's economy. So it's clear it's not a Chernobyl level incident - we can all rest easy.
