Is it vaccines? Processed foods? A lack of Christian morals?

HEALTHCARE SHOULD BE A GOVERNMENT SERVICE

Healthcare should be a total financial loss. Like a military or a library, the value is in the service they provide.

Fire the MBA shits who have made a "career" of turning hospitals into profit generating businesses and there will be an overnight boost in care given per dollar spent.

You might be more paranoid than I am, but I check every unexpected link from messages claiming to be businesses if I open them at all. Usually I'll go to their website and check for what the message claims if it seems plausible.

Sound like the vehicles are not safe enough for use on public roads.

The Steam Deck has an absolutely fantastic set of inputs. If the new controller comes with the all the same bells and whistles then it will be well worth the price.

No one in the western world who has a smart phone is not aware of phone scams. Everyone has been told not to trust random links in text messages, usually by the banks and businesses that are being used in these scams, but 'just this time, it looks safe, they've always been safe before."

This kind of online-safety thinking needs to be drilled into people like wearing seatbelts and brushing your teeth.

Only a problem if you follow random links you get in your messages. So old people and the technologically illiterate.

My FPV goggles have no internal battery, they need to be run off a 2s-8s LiPo or 5v from a USB port. This lets me use a reasonably safe power supply instead of strapping a raw lipo to my body.

I bought a Cetus X kit last October and an Air65 shortly after, since then I have flow about 1K packs and loved every one. Learning to fly smoothly and calmly was a huge challenge in the beginning so I am pretty satisfied with 45m/week of progress. This is the Air65 in my favorite park, though the Cetus X is a pretty good fit there as well.

Warning there are some tall-ass images in this post.

A few years ago I got mad enough at the temperature gradient in my town house that I designed and build a bunch of ESP8266 sensors to feed data into an RRD so that I could have some pretty graphs to be angry about as well. (As of this week I have also started logging stats from my UPS and server.) Using the minimum of HTML and CSS I threw those graphs, a map of the previous day's incoming network traffic, and some convenient links onto a homepage that I use on all of my devices. At a glance this tells me if the furnace/AC is working, if my server is having a fit for unknown reasons, and if the local power grid is playing it fast and loose with the voltage and frequency (which I suspect they do).

Clicking the temperature/humidity data leads to a long term data page covering 2 years of data in varying resolution. The gap last fall was when the garage sensor failed and I was waiting for Aliexpress.

There are also long term trends for the server load and UPS but they have only been logging for a few days so there is not much to look at.

Clicking the map on the home page leads to a text file containing a summary of all incoming traffic to apache and ssh. The ssh server is on a high port number and doesn't see much traffic but occasionally a persistent bot will find it.

Everything but my landing page (this animation in p5.js https://old.reddit.com/r/cellular_automata/comments/1djwjbu/waves_processingorg/ with the text "Hey this isn't where I parked my car" overlayed) is behind basic auth or better and I have push notifications set up for every ssh login (even my own), in 5 years I have never had a successful login from an attacker, this is not an invitation, have mercy.

All the data is gathered with python scripts and stored in RoundRobinDatabases or, in the case of network data, digested down into a CSV. The climate sensors respond to requests on port 80 with the temperature and humidity separated by a comma to allow for easy polling. The map is generated by looking up the IPs' information on Shodan then plotting the location data if it was present.

Absolutely none of this is the ideal solution, there are existing projects that cover literally every aspect plus a dozen extra features I could never hope to implement. I wrote as much as I could from scratch just to see if I could, it's more fun to drive a shitty car that you built than one you bought from the dealer.

Aaaand I accidentally made the UPS database only 24hrs instead of the 10years I had intended. Lucky for me rrdtool has a function to expand an rrd without wiping out the data!

Using a vinyl cutter and mini-sand blaster I made some alternate universe corporate schwag! I like the idea that someone might have swiped these during an interview before both companies had their 'accidents.'

I got my hands on some really weird EL panels and did a little dive into how they work. I still have no idea where to get more but I think they may be DIY-able.

First Functional Print (www.thingiverse.com)

I was gifted an unused Ender 3 Pro two weeks ago and managed to model and print an adapter to connect Sony E-Mount cameras onto a 42mm dovetail used by microscopes.

Bed adhesion, leveling, stringing, clearance issues, blobs and permanently welded supports, I got to battle it all but thanks to the massive volume of community support I worked my way though.

I was given an Ender 3 Pro last week and after a few bumps managed to successfully CAD, slice and print a booster seat for my phone. The caddy as it was would grab the volume down button on my phone, this little wedge solves the issue!

I learned this week that many high speed CD-ROM drives used balancing balls on the spindle to stop discs from vibrating at 10Krpm.

Between the platter that supports the CD and the motor there is a puck with a toroidal void containing a few ball bearings. When an out of balance CD is spun up the spindle and disc together rotate around their common center of mass, some point between the spindle and the edge of the disk. This means that the void containing the balls no longer rotates around it's center, it spins like a hula-hoop around the spindle/DC center of mass. With the "lighter" side of the system being farther from the center of rotation the balls roll 'down hill' towards the side of the void that is experiencing more centrifugal force. Eventually enough balls will collect on the light side to perfectly cancel out the heavy side. If there are too many balls they will distribute themselves inside the void until they cancel out each other's weight!

The link leads to a scaled up demo of this using an empty water bottle and steel BBs.

Rant in a totally different direction. Carbon Capture Is Not Sustainable!

Unless you can capture 1 ton of carbon using less energy than is extracted by burning 1 ton of carbon, you can not capture carbon. Carbon capture will ONLY work if the energy you use to capture the carbon does not add more carbon to the atmosphere (nuclear, wind, solar) but having to run a supplementary power generation tech just to negate the effects of your primary tech is just stupid, fossil fuels no longer a viable option.

Why would anyone NOT parse a tab as whitespace? Like, python really wants you to use spaces but will still let you use tabs if you are consistent.

Because two of the big platforms might cut off your traffic for using any of a long list of arbitrary words.

It's pretty fucking disgusting to self censor inoffensive language because an app might stop showing your memes to other mouthbreathers.

but plans to list it for $150,000 less than he bought it for a year ago – its value walloped because in a matter of months, it will no longer be useable in most cases as an Airbnb, “The revenue stream dictates the value,”

The system works!
