LoRa to the Moon and back: Messages bounced off lunar surface using off-the-shelf hardware

Thumb Up

EME, LORA and Meteor Scatter

Yep, first read of the story didn't say anything spectacular. In the HAM world, we have done this for quite a while with some cheap gear.

I don't see a mention on the Frequency used by Lora and considering the modules are available in 433Mhz, 868Mhz and 915Mhz, it may make a difference. Certainly 433Mhz would be quickest to get working with a borrowed ham yagi and suitable amp.

Might be harder with 915Mhz but i've not read up on the propagation properties of this frequency at distance. Normally higher frequency = less penetration.

What I find more of an achievement is the use of Meteor Scatter for communications. Bouncing your radio signal off of the ionised trail of a meteor passing through the upper atmosphere when that trail may only last from a few seconds to 30 seconds.

Wheelie bad end to 2019 for Canyon Bicycles as hackers puncture IT systems



Ah well they host their servers at 1&1 which says it all really. Not the cleanest of places when it comes to hosting.

No merry Christmas for SwiftStack staff: Enterprise cloud storage biz axes workers amid strategy shift


TBH. Better to be redundant before xmas so you can react and change your spending limits. Trying to juggle redundancy and the credit card bills after Christmas would be worse.

I'm just not sure the computer works here – the energy is all wrong


Re: Ah, the carefree days of yore

I learnt the hard way when I bought my future wife a set of Jump leads for her car as a christmas present. 20 years later and the story is repeated to family and friends with much amusement.

The leads are still going strong too.

Yes I guess they could sack you and you lose your redundancy package.

BA's 'global IT system failure' was due to 'power surge'


Maintain your generators

Whilst working at a company in 2001 we had a total power failure to the building. Quite correctly, the UPS maintained the integrity of the server room and the backup generator started up as commanded.

Upon contacting the power company we were told it would be down for at least an hour. Our building services guy said we had fuel for the generator for 48 hours. Two hours later the generator dies.

Turns out the fuel gauge was stuck on full and the tank was close to empty. Dipsticks are your friend.

Miss Misery on hacking Mr Robot and the Missing Sense of Fun


prefer Halt and Catch Fire

I gave up on Mr Robot half way through season 2.

However, Halt and Catch Fire is brilliant. I just had to break out a copy of MAME after watching the first couple of episodes.

Fire brigade called to free man's bits from titanium ring's grip



My wedding ring is Titanium and at the time of purchase, I had the choice of 99.99 pure Titanium or a Titanium Alloy.

I picked the pure Titanium as it is softer than the alloy and shouldn't be a problem for emergency services if I get into a situation requiring it's removal. It's certainly too small to go on my dick so the situation in the story shouldn't ever happen.

Barnet Council: Outsourcing deal with Capita has 'performance issues'


Re: libraries closing

Sounds exactly like my town. We have secured free parking after 3pm for the car parks but it's only a trial. All the shops seem to be charity shops too.

Re: so.. Back to briefcase

Many years ago I used to take a briefcase to work, partly because it was a birthday present from my parents and partly because it really was useful to carry my lunch and magazines to read. I also had quite a craving for cream cheese that comes in toothpaste style tubes and TUC biscuits.

One day I was rushing to get away from work to go to the pub only to find that a couple of my colleagues had squeezed cream cheese onto the handle of the briefcase and place the handle back down flat so you could not see the cheese. You can image the mess when I grabbed the handle to have cheese squeezing out between my fingers.

I of course arrived late to the pub and to much smirking and laughter from people around me. I know who you are even if at the time I did not acknowledge that I had been pranked.

Wi-Fi commuter fears


£50M ????

That's seems to be a lot of money wasted. I wonder how much was creamed off the budget to line the pockets of manglement types?

Took me a while to realise it stood for something else other than Chinese Export.
