Heart aerospace's website indicates the X1 demonstrator has a 140kt "VNE" - never exceed - speed. So it's probably safe to assume cruise speed would be closer to 100kt, and $5 of electricity used in half an hour might equate to around 50nm straight line distance.

It's pretty impressive for a plane roughly equivalent in size to a 30-seat turboprop airliner like the EMB 120

The X1 demonstrator is more comparable in weight and power to an EMB 120 Brasilia, a 30-seat turboprop. Forum chatter seems to indicate those burn around 1000 lbs per hour, or $335/hr in fuel using the $0.59/liter price you mentioned.

Dropping down to $10 is still pretty decent lol

It's mostly correct, but even before McDonnell Douglas in the early 90's Boeing actually had repeat issues of 737 rudders reversing direction in flight, causing accidents. Their response was exactly the same as the MAX8 crashes, cover it up and blame the pilots. It even sounds to me like they tampered with evidence according to Admiral Cloudberg's telling of it: https://imgur.com/a/5wcFx8M

Boeing, which had packed the valve for shipping, did not explain why it kept the spring and the end cap. It instead tried to steer the NTSB toward a conclusion that the crash was caused by a wind rotor

I certainly still agree things got MUCH worse after the merger though

Its such an insult to say
"Reddit delivers the opposite: deep discussions, passionate debates,"
When they have continually pushed to minimize that format of reddit. The official app works the same way as all of Meta's products, infinite scrolling content, their new website design severely restricts the comment section to just a few replies, instead requiring you click "see more" over and over if you want to continue reading a discussion. Now they are attempting to gatekeep their old.reddit format as well, restricting the ability to view discussions even further.

I have been a reddit user since the mid 2010's and it is so frustrating to see what once was truly the best place on the internet to discover new things, fall so far

Have to be accused of a crime first for this to apply. The victim here was purely the target of extra customs search due to his support of a politically unfavored cause

I spent a lot of time researching and testing different methods for that, the only thing that worked was LACT in Linux. Using that I was able to undervolt 100mV and GPU power usage dropped about 10%. On my B450 ITX board with a Ryzen 2400GE CPU the entire system pulls 30w idle from the wall, and about 300w inferencing with VRAM filled. (330w before LACT).
My fan solution ended up being to buy the 80mm 3d-printed shroud off ebay, the fan that came with it was super loud so I switched to an arctic p8 Max, and control it with the motherboard targeting a t-sensor header with the probe attached to the backplate.

The article talks a lot trash about AMD and ROCm but vulkan works fine too. In fact from a datacenter GPU standpoint there is an AMD option called the V620 available on US EBay that I was able to haggle to $350, with 32GB VRAM, 512GB/s bandwidth, and runs the same Qwen-3.6-27b at about 20t/s. I would argue that's even more cost effective.
It requires a few of the same fan shenanigans this guy did but there is no need to pull specific past software versions to make it usable in Linux
