@whitequark@social.treehouse.systems 100% feel that and understand — a few months ago I installed windows on libvirt and omg, the endless upsell attempts, the quirky configuration dead ends that you have to go back and start over. Something I would only do for family 😂

Not aware that they ever tried to get them to leave. Of course they also had (maybe still have) Bison which was pretty cool.

@MLE_online Yes. Ethical people do things because they are the right thing to do. But it's important to point out that you sometime really need systematic change to really move the needle. I drive a civic among the crowds of SUVs because it's the right thing to do IMHO. But we need to change regulations if we want to bring an end to the era of American Hugemobiles.

Last time it was the rise of Honda and Toyota with decent small cars. Now it’s Chinese EVs.

@blogdiva @iFixit I wonder if we will ever get CXL pice-attached memory support in any kind of commodity device ... it would be lower performance than main memory but a lot better than even flash storage. Just thinking of all the weird PCIe hacks people have done to attach GPUs to stuff, this would be in the same category.

@akent Does it touch on “waterbugging”? Which started from a car dealer dropping an air-cooled bug into a river and it floated for half an hour. Waterproof the distributor, add a snorkel, snow tires on the rear wheels .. now it’s a boat. Sunroof for emergency exit and bilge pump or passenger with bucket recommended.

@pluralistic@mamot.fr Maybe it’s a different Ting mobile, but the one I have used for years does have decent rates but has been sold for Boost (which is what my phone now reports) and is quite backwards in that they do not support eSIMs (at least as of the last I asked at the end of last year) which means I’ll have to switch carriers if I want to use a newer phone than my current iPhone 13 Pro.

Replying to @ned@beige.party
@ned@beige.party @advicepig@hachyderm.io @jonshell@mastodon.energy It helps certainly. My older car is a 2001 civic sedan with a 5-speed manual. I don’t downshift super aggressively though so some use of brakes is needed. Even though it has been mostly used for highway driving, it still has usually needed brake service by 75k … current mileage is over 400k 😂 it’s been to the moon.

@advicepig@hachyderm.io @jonshell@mastodon.energy Regenerative braking goes a long way to eliminating friction brake wear. Even my civic hybrid now has 185k miles on it and the brake pads are only at about 50%. Past experience with normal civics is that you need pads replaced somewhere between 50-90k miles. Suspension components however ... there is no difference here, and EVs tend to be heavier with current battery technology, so more work for those systems.

@rygorous I was a grad student in a lab that had one of these in the mid 90’s. We used it to do stuff like visualize 1024x1024x1024 cubes of data from sola convection simulations .. it could render this real-time as a voxel cube. After hours, yes when glquake came out, you bet we tested it.

@jmax Yeah I wish I could have brought a dog! Mine are all either too elderly for the walk, or not so keen on pets from strangers.
