A glossy advertising leaflet pushed through my letter box has lots of photos with captions describing the photos. Except one of the captions is "Photo captions are the most read body type in a publication".

Oops!

I politely refused a gift offer for a pair of Logitech headphones. I'd heard of many who had ended up with either hearing problems or even deaf from using them at high volumes. Not sure I trust myself, to both remember and to lower the volume to a reasonable level.
 

German robots hunting the sea for WW2 bombs​

https://www.bbc.com/future/article/20240621-the-robots-hunting-ww2-bombs-in-the-sea

A boxy robot crawls across the seabed off northern Germany, reaches through the murky water with a metal claw, and picks up its target: a rusting grenade, dumped into the sea after World War Two. Overhead, another robot swims along the surface, scanning the seabed for more munitions. More robot claws reach into the water from above, plucking bombs and mines from the sediment.

A pilot project backed by the German government will be deploying these and other technologies in a bay in the Baltic Sea this summer, to test a fast, industrial-scale process for clearing dumped munitions that are polluting the North and Baltic Seas. The project is part of a wider €100m (£84.6m/$106.9m) programme by the German government that aims to develop a way to safely remove and destroy munitions littering the German parts of the North and Baltic Seas – a toxic legacy that amounts to an estimated 1.6 million tonnes of dumped explosives and weapons.

"These munitions are rusting, and our research has shown that over time, they're releasing more and more carcinogenic [and other toxic] substances, traces of which have been found in fish and mussels," Greinert says. "The longer we wait, the more they're going to rust, and the concentration of harmful substances in the water is going to rise. So now is the moment to figure out what to do with this stuff, while the munitions are still intact enough to be grabbed."

https://pubs.acs.org/doi/10.1021/acs.est.8b06974
Underwater munitions containing millions of tons of toxic explosives are present worldwide in coastal marine waters as a result of unexploded ordnance and intentional dumping. The dissolution flux of solid explosives following corrosion of metal munition housings controls the exposure of biological receptors to toxic munition compounds (MC), including TNT: 2,4,6-trinitrotoluene, RDX: 1,3,5-trinitro-1,3,5-triazinane, and DNB: 1,3-dinitrobenzene.

It doesn't make sense to arrive at a port, usually outside, e.g., off the coast, and sit idle for days.
Here is a quote from this weeks local newspaper in an article about ships waiting to dock:
[...the port] "continued to have the fastest truck turnaround times, the shortest berth stays and the lowest anchorage rates of any terminal in" [the bay].

The theme of the overall article seems to indicate that the holdup is the port unloading process not meeting their time targets. Although it is rare, I have seen two freeway lanes backed up with trailer trucks for about 1.5 miles in each direction trying to get into the port. So occasionally something does go wrong to trigger this.

I don't know any truck drivers hauling from/to the port, but I expect there was a lot of strong language THAT day!

Cheers,
Tom
 
Life is good.

My friend applied to a job where he was supposed to have experience working with Autistic people ( kind of strange for an IT job). He cited his experience with programming and databases as experience; you leave out a single comma , or a single letter from a 50 word query, and it won't run. Not sure HR will be too amused.
 
Bittersweet graduating university and moving to a new city to start a new job, whereas my partner is about to head far across the globe for a year abroad. It'll be a great experience for her, and at the same time it'll be so strange not having her here. But if you love someone then let them go, they say -- I wonder what we'll both be like in a year's time.

What’s the job?
 
Good luck!

So, is there really something to this Cobol thing, the high demand for programmers so many claim
there is? Some make it sound as the next Gold Rush.
Edit: Along similar lines, British Guyana( Guiana, Sp?) Is supposed to be experiencing an oil rush, from recently discovered oil sources.

Today's 'winner of bragging' is a noname battery with a promised 6800mAh capacity: measured as 900mAh.

The same equipment measured a proper 3500mAh one as 3450mAh.
 
I cracked open an egg this morning and it was black inside. Never saw that before. :oldruck:

This seems to be a trend in online advertisement. I was quite gullible and thought I was buying a pair of flexible solar panels for 10¢/watt. Turns out the seller either conveniently added a zero or left out a decimal point from the wattage as the panels were actually 100¢ per watt. I wasn't too upset as I was quite impressed by their watts to volume and weight ratios.

This seemed interesting. A study of stupidity:

Is there anything more annoying than voice messages, other than 12- second voice messages?
I find TV ads most annoying. Don't get me wrong, I am a capitalist (not Adam-Smith-like, but in general) and accept ads.

But they are always louder than the program they are in. So I switch the channel or mute the tv.
How stupid can one be to provoke such a behavior?

I also tend to read the news ticker at the bottom of a news channel. Often more than an entire circle because I missed something. Now, if the ads kick in, they turn off that ticker line, i.e. I switch to another channel that doesn't have ads at that time, or I read it elsewhere.

I am annoyed by the stupidity that causes me to leave their ads instead of just letting them calmly run in the background. One would think that a background ad is still more valuable than no ad.
It is their stupidity that annoys me. TV channels and ad-agencies.

What's puzzling, funny at times, annoying, or all, is trying to figure out just what the ad is about and which company it's from. Food? a Movie? What the $#@n is the ad about??

True. Shouldn't they at least place their logo somewhere?
WHAT! And get known for messing up a perfectly good program?

Heresy, I say. Heresy!
