Who didn't know that the US was the Mecca of bigotry, racism, homophobia, and corporate greed? Seriously, I can't be the only person who saw this coming as soon as Trump's name went on the ballot in 2016.

The only reason there isn't more outcry about John Deere is they have successfully painted farmers as the bad guy, trying to "steal" business away from the poor tractor corporation. Same goes for 3rd party repair techs performing "illegal" modifications to iPhones.

affordable Chinese EVs

A Trojan Horse of monumental scale. China's long term goals is to run the world, they will use any opportunity they get to get economic control over other countries. Putting millions of vehicles on the road that can be disabled by the Chinese government every time we disagree is not a smart move.

And this isn't just fearmongering about Chinese tech, all modern cars have cellular modems and can be disabled to some degree by the manufacture, but China has 100% control over big businesses. If they say no commuting in Canada tomorrow, it'll happen.

This can be done without inviting AI and crypto bros (the same people) into Canada. Electric car chargers can be required to follow a charging profile put out by the supply authority, then as people go to bed at night chargers can be ramped up and the base load increased.

"It's only a little" is perfectly reasonable when 'a little' is below the threshold of doing harm. For example, mercury compounds are still used in medicine because the risk of harm is negligible at the concentrations it is used. Flourine is cartoonishly dangerous but it is in water and toothpaste.

Small aircraft make up a very tiny fraction of gasoline consumption and an engine failure is a lot more serious for them than a car. It's really only a problem if you spend a lot of time hanging around airports.

It could be, but it could also be trivial given the 8x lead consumption in the 80's.

I think the whole protein powder industry is a fad but having the CBC legitimize claims like this is how you feed anti-science smooth brains. They get to point at the 'health product' and call foul because the CBC said there is killer lead in it. It took seconds to find the Canadian lead numbers, the CBC could have done the same to give context.

Aviation fuel (like personal sized planes) is still leaded because it makes the engine more reliable.

This whole hype is bullshit, Canadians get 0.1ug/kg body weight per day. Even the 'worst' one listed still falls within the norm for an 80kg person.

[–] nik282000@lemmy.ca 2 points 1 week ago

Look up the numbers, Canadians consume on average 0.1ug/kg body weight per day. The 'worst' one listed is still within the norm for an 80kg person.

A single serving of these protein powders contained between 1,200 and 1,600 percent of CR’s level of concern for lead, which is 0.5 micrograms per day.

Canadians consume on average 0.1ug per kg bodyweight per day so that 0.5ug 'level of concern' is bullshit.

https://www.canada.ca/en/health-canada/services/food-nutrition/food-safety/chemical-contaminants/environmental-contaminants/lead.html

1600% of that suspicious limit would be within the norm for a an 80kg (175lb) person.

Do you lock your door? Why, people don't just go into other people's houses, they're not inclined to do so.

The point is having vehicles vulnerable to such trivial abuse is unacceptable. It only takes one cunt who decides that he wants to randsomeware every Toyota in the world to spoil the party.

 

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!

 

Got lucky with a clear night.

 

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.

 

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.

 

// Randomly spawn drops

// Take a random fraction of each cell move it down, or down and to the left or right

// The remainder of the fraction stays where it is

// Subtract a constant small value from all cells to prevent rain from accumulating

 

I found a box of CD-Roms and floppy disks in my mum's basement and damnit, I want to play them! I could use emulators, DosBox or VMs but it's never quite the same as having the real thing, so between an eBay mobo and a box of old parts I managed to build my new gaming rig to cover 1990-2005.

Its running a P3 at 1GHz, 512MB of ram, and an ATI Xpert98 with 8MB of memory. As I didn't want to run an old IDE drive with a million hours on it, I tried an SATA-IDE adapter, it caused some issues during the install but that just felt like the standard Windows experience.

Though unpopular, I went with ME for 2 reasons, the first was Dos support, the second is that I went from W95 to ME as a kid, 98 wouldn't have felt the same. The install bricked twice with video drivers but I finally got it up and running with the default drivers and an 18" Samsung flat CRT (runs up to 1600x1200 at a nauseating 60hz).

So what were your favorite games from the 90's and early 2000s?
