The technique I've used to fill a balloon with rice:
- Take a small plastic drinks bottle.
- Cut the bottom half off to make it like a funnel.
- Remove the lid, and stretch a balloon over the neck.
- Invert the half bottle so the balloon over the bottle-neck is hanging underneath.
- When you tip some rice into the funnel, only a few grains will fall into the uninflated balloon.
- Now put your mouth/cheeks against the open end of the bottle/funnel and blow. This will partially inflate the balloon, and all the rice will fall in. Done!
If a balloon is made of a thin neck and a round body, you're chopping the neck off near the bottom of the neck. You're then left with a round rubber pouch for the contents (rice). Use two balloons in opposite directions so the closed end of the outer layer covers the opening of the inner layer.
Great for juggling balls - nice weight and very grippy.
I helped administer the CheckPoint commercial version of this before 2010 in a large enterprise (Checkpoint Integrity it was badged as). Really good product though we did have some bugs with it - I do remember the developers from Israel got involved and were very capable.
It mostly worked exactly as you would want a desktop firewall to, and integrated nicely with Cisco VPN tech, so you could ensure Integrity was operating correctly before fully opening up the tunnel for access to corporate assets.
I think we call it "dark" because the term was coined when the English language was used in a more poetic sense - at least it seems like that to 21st century-me. "Dark" = "it has not been made visible to us".
I've just been reading Narnia stories to my son and lots of the language seems dated and initially confusing but very descriptive and more poetic. Even though that was just in the mid-20th century.
"Dark side" is used to describe the part we never see from earth's vantage point, not a part that gets no light from the sun. Definitely confusing for the uninitiated though.
Oh yes - run Frigate on a mini PC or home server. It runs best in Docker. And it should work with any cameras that support RTSP and provide H.264 video.
I'm not affiliated btw, but I found the instructions really useful - they walk you through an install of Debian 13 (small version of the OS with minimal components), set up low maintenance options (auto updates etc.), install Docker & Frigate, and set up your cameras for best performance depending on your needs.
Keep everything local (if you want). I also integrate with HomeAssistant and expose that through a free CloudFlare Tunnel for access when away from home.
CloudFlare tunnels by the way - these are a great solution to accessing home-network resources without punching holes / port-forwarding etc. because all the access is outward from the home network, then an authentication layer added by CloudFlare.
If you're plotting primes, all the coordinates where you're not plotting are non-prime - so every 2nd coordinate will be blank. As will every 3rd and every 4th, 5th, 10th, 11th. etc etc.
I think relying on the internet to have a trust mechanism built in is a bit like relying on our road-builders to ensure our vehicles are safe.
While the average internet user will just trust the sites and apps they use, there's nothing stopping those who are able from designing/building/using/sharing technology which they can reasonably trust. The building blocks are there (crypto / networking libraries etc.).
When open source software gets outlawed, I'll be worried.
I drop photos (from whatever device) into a folder on my NAS and they get automatically sanitized of EXIF data, and resized/bordered ready for posting to the internet.
It's simply a cron & bash script on a server that monitors one NAS folder, then drops the output into a second folder where I can pick them up and use them.
Using kdenlive for video editing on Linux has served has a good reminder many times to save often.
Cloud and mobile apps are often very good at taking this task away from a user, but it's worth remembering to take responsibility for saving/backing up files that have value.
I'd expect it to be quite high (deaths per TWh) while the technology is new or advancing fast, both because the energy production will be low, and because there must be more risk in newer industrial-scale technologies.
Deaths per TWh in Offshore wind vs Onshore wind production would be interesting to see too.
Wow, this comment just got me thinking. If I've got good at taking well composed photos, according to common photography techniques, might they have less of that time-machine, memory-jogging quality? I'd like to have both - maybe I need two sets for photos!
I think this may have been the result of banking malware (e.g. Zeus back in the day) which was hooking OS calls to capture keyboard input and steal passwords.
I'm not sure whether the on-screen keyboards would be vulnerable in other ways though.
I have 4 RPi's in frequent use. The one in my kitchen (music player, Pi 2 model B) needs a clothes peg to squeeze the SD card into the reader otherwise it won't boot.
So that's a 25% failure rate for me as far as hardware issues are concerned.
It has worked reliably for a few years with the clothes peg though!
I can see some benefit, even if it's just keeping their brand visible to the market. It shows they're not going away any time soon and might just help keep momentum.
As a multiple* RPi user, it's always heartening to see them doign well.
