If I can't open/access the Instance, how can I view its error log!?

Did the test. I officially have the power of covid.

Sorry to hear that. Look after yourself...

I programmed my Linux laptop to make an alarm sound and blink the screen when it detects the 433 MHz signal of this cheap garage door remote controller with the RTL-SDR radio receiver dongle. The Gqrx radio receiver application shows how the signals from the two upper buttons are actually more close to 434 MHz. This is a bit like the idea on this web page, where a low frequency radio remote controller is used for sending Morse code to someone: https://www.instructables.com/do-morse-code-with-an-rc-car-remote-and-here-it-on/

I still need to get another remote controller at another frequency, 868 MHz, and preferably with a longer range signal, to be able to send a larger variety of "messages" with these. I'm also getting an active, amlifying Mini-whip antenna that can probably detect these signals from a longer distance.



Edit: for some reason the sound in the shared Imgur video occasionally plays delayed compared to the image when I watch it.

Why am I going to the meetup for " Make friends with Data Science"( they asked)? Because I've always been friends with Data Science .

Don't know about limiting cases. If an event somehow has 100% probability of occurring, then the odds are 1:0 ?

Time for a change.

Coaches/Bosses/Police/etc. can "yell at" people "under" them.

If that is an acceptable form of communication, then students, players, civilians, etc. ought to be able to yell right back if those above them do something wrong.

What do you think about our hiring insights?
I'm not sure how you can hire abstractions, but you do you.

The Q Q has currently 30 hours of waiting time. Heck, I didn't wait as long for Napoleon.

Why do so many people search beaches on their vacations? Do they miss their former home?

Savannah would be a major tourist spot too in that case. Epping forest quite popular however so you could be onto something.

You beat me to it. I think they're cold turkeys, so my guess is that either Bill or the cartoonist is giving up smoking...?

My niece goes to Uni sat. I know personal stuff is not allowed but it's a bit of a thing.
It's not Science so obviously I'm disappointed but I think she will absorb things there.

I don't know, I rely on Bill and Jim for direct life sciences jokes. They make sense to me. Subliminal, abstract, deep, weird, tenuous stuff I look to Fresh and and the physicists.
Hopefully he will clarify. I hope it's a nice ending, those birds seem to be looking for guidance.

The "joke" is the wrong way. The ducklings should follow the ducks, not the way the cartoonist put it.

... or they only want their coat back.

It's a guy they are looking at not a duck and no one is moving. Also what is the significance of the snow?

It's winter, and the guy's selecting a pre-plucked frozen chicken for dinner from the outdoors freezer.

The birds are cold bcause all their feathers (insulation) has been used to make nice fluffy jackets (like on the guy in the picture).

Is this a shits and giggles project or...are you anticipating a hostage/kidnapping situation?!

The first of those... I also made a video about how much copper-nickel metal fabric you have to wrap around a cell phone before it disconnects from the mobile network, but that video was too large to upload to Imgur. The result was that you need quite many layers of that fabric, and the same if you try to stop a Bluetooth speaker receiving the signal by wrapping it inside that.

In terms of driving songs, Yes' "Roundabout" ( ' I'll do the Roundabout ') is a lame counter to Deep Purple's " Highway Star".

Am I the only one who's watching football on Sundays? Why don't we have a football thread? I want to type "The Bucs were bad, but the Saints were worse." somewhere.
