They already did.

There's that 'Raw Edit' video that is missing over a minute of footage because they forgot to edit out the timestamps.

I point out that in the USA, a dude can literally shoot an unarmed teenager with skittles in their pocket (likely 2nd degree murder or worse) and a Jury of his Peers will acquit him.

Wtf?

  • Premeditated Intent: Murder
  • Intent without premeditation. Heat of the moment: 2nd degree Murder
  • Doing something you weren't supposed to and killing someone: involuntary homicide
  • Failing to do something you were supposed to and killing someone: negligent manslaughter.

Who made this meme (and topic) and why is everyone so ignorant of the law? This almost certainly is vehicular manslaughter case or... If it can be suggested that it's the pedestrian maybe was partially at fault it might be negligent manslaughter (ex: failed to stop when someone jumped out).

A bit of a high level beginner friendly overview. Useful for people getting into the hobby!

Power engineering is a Masters level subject however, so don't get ahead of yourself. Studying up the difference of GaN vs SiC vs TrenchFET or whatever new tech is always work. It's always hard to keep up with technology.

Unfortunately, this is not the appropriate place for a discussion.

BestOfLemmy aims to highlight good arguments / discussions / topics from across Lemmy. I don't have the abilities to really do a fair and just debate here.

Why would an American tech millionaire believe in the power of money and become subservient to a Billionaire?

I dunno. Good question.

I was an active subscriber who regularly read WashPo.

Ruth Marcus, Alexandra Petri and a whole slew of other liberals have left the post after the 2024 election and various tampering by Jeff Bezos. Or have you not noticed the change of writers yourself??

The ones who remained are hardly NeoLiberal, but overall have shifted farther and farther right. Jeff Bezos killing a few key OpEds have made it clear to the liberals that they are no longer welcome at the Washington Post.


Or what? You gonna try to convince me that Hugh Hewitt is a liberal or some shit?

You youngsters will blame the next generation as well. You just aren't old enough to see the pattern yet.

Washington Post is Murdoch connected as of December 2023 (new leader and Bezos began to flex his muscles at the paper). I hesitate to call it neoliberal. It's moved right of that.

What’s that one dude who wore the hoodie and had the stroke and then turned out to be fucking insane? My guess is the stroke wasn’t what made him a republican.

His staffers were literally crying and large numbers of reports are that he is a changed man after the stroke. Its uncommon, but it happens. Brain damage can result in personality shifts.

He's some Pennsylvania Politician, I forget his name but maybe a Senator.

Anyone who possesses the kind of money that they possess, even Yang, are only in it for themselves and their cronies.

Well yes. But that's traditional American Politics and its been like that for a long time. People prefer the devil they know (money / greed) rather than other vices.

If anything, being openly greedy makes people more comfortable with the personality.

Now AI can sort through the hours of traffick camera footage

No it can't, not without major hallucinations and/or basic errors (ex: Black People tend to be misidentified).

That's the big thing about this AI push, it's subtle mistakes are fucking people over right now. If AI actually worked reliably that's another thing. But right now, people are mostly pretending that AI works and/or ignorant of its flaws.

Our timeline is officially stupider than fucking South Park.

 

I'm doing some Galois Field / Cyclic Redundancy Check research for fun and I've come across an intriguing pattern that I need a data structure for.

Across the 64-bit (or even 128-bit or larger) spaces, I've discovered an interesting pattern relating to hamming distances that I'd like a data structure to represent.

I'm going to need something on the order of ~billions of intervals each having somewhere between 1 item to ~1 billion per interval. And I'd like to quickly (O(1) or O(lg(n))) determine if other intervals intersect.


For 32-bit space I can simply make a 512MB Bitmask lol and then AND/OR the two Bitmask. Easy

But for 64-bit space I'm stuck and a bit ignorant to various data structures. I'm wondering if someone out there has a good data structure for me to use?

I've read over Interval Trees on Wikipedia. I'm also considering binary decision diagram over the 64-bits actually. Finally I'm thinking of some kind of 1-dimension octtree like datastructure (is that just a binary tree?? Lol. But BVH trees in 3d space seems similar to my problem it's just I need it optimized down to 1 dimension rather than 3.) Anyone else have any other ideas or cool data structures that might work?

 

I've been informed of an attempt to consolidate all the Tesla communities into teslamotors@lemmy.zip (for Lemmy.world users, you can still access it here: https://lemmy.world/c/teslamotors@lemmy.zip).

I'm interested in hearing the community's thoughts on this. Consolidation is the name-of-the-game right now in Lemmy, we just aren't big enough to have critical mass especially as tons of different communities are split off like this.

/r/RealTesla from Reddit was necessary in the 2010s where Elon Musk was running popular and it was impossible to get a critical word in about bad Tesla service, the lies from Tesla's sales about their fuel gauges or even have awareness of how explosive Li-ion batteries are.

Today, its becoming clear that Tesla Lies (led by Elon Musk) is the norm. And we can see that today a "general Lemmy" community about Tesla that its possible to be critical about Tesla even on a Tesla-focused community.


That being said: I'm not for closing down /c/RealTesla. We need a "signpost" for the /r/RealTesla Redditors who are beginning to branch off to Lemmy.

But I'm considering leaving a signpost to teslamotors@lemmy.zip, especially since they're more active at the moment about Tesla news. I'll try to keep this community here active as a lifeboat for lost Redditors however.

What does everyone else think?

 

Just a few protests of note happening around the country. I know there's more but these are the instances I was aware of.

 

Tesla protests are beginning to get more organized.

/c/technology was the most active by far (more so than /c/cars), so I'll post here again first.

Stats

The following stats are winter tests (10F to 30F. Or -10C to 0C).

  • L1 Charger from Home is 2.05 mi/kwhr (12.0 mi/electric-$$. 17.1c per kwhr home costs) in this deep cold.

  • L2 Charger from Work is 2.8mi/kwhr (14.0 mi/electric-$$. 20c per kwhr work-charging costs).

  • 43 Miles per Gallon gasoline (13.9 mi/gasoline-$. $3.10 gasoline during test).

  • L1 Charger is closer to 2.8 mi/kwhr during 60F (15C+ temperatures).

  • L2 Charger is closer to 3.5 mi/kwhr during 60F (15C+ temperatures).

Conclusion: The cold (10F to 30F) has made the Li-ion batteries of this car SIGNIFICANTLY less efficient. We're at the point where L1 chargers are more expensive than gasoline, while L2 chargers are roughly on part with gasoline.

I recommend anyone who gets an EV to get an L2 charger. Not only for the convenience of far faster charges, but also because of the incredible improvements to cold-weather charging efficiency.


There were some pro-EV fans asking me to more carefully test the gasoline usage in the winter. And now you have the stats. I can solidly say that gasoline is worse during the Winter (down from EPA estimated 48), but not dramatically worse like the electric engine gets.

The above gasoline test was done over an entire week of driving to reach the 200+ miles I thought was needed for a solid test. I performed it by running out of electricity (all the way down to 0%), then driving to a gasoline station and filling up. I memorized the exact pump I filled up at.

Then, after 200 miles across a week, I came back to the same pump and filled up exactly the same. I then counted the gallons that came out of the pump and divided out based on my trip odometer. I was 203.5 miles of driving total with 4.734 gallons reported from the pump.

This NEEDS to be saved. People will forget if we don't save this.

The Prius Prime is a dual fuel vehicle, able to run 100% on Electric, or 100% on gasoline, or a computerized blend in-between. This presents me a great opportunity to be able to do a direct comparison with the same car of an EV engine vs an ICE engine.

  • Toyota computer claims 3.2mi-per-kwhr.

  • Kill-a-watt (https://en.wikipedia.org/wiki/Kill_A_Watt) claims 2.2mi-per-kwhr.

  • Additional 1.5% losses should be assumed in the wires if you wish. (120V drops down to 118V during charging, meaning 2V of the energy was lost due to the resistance of my home's wires).

  • Level 1 charger at home (known to be less efficient).

  • Toyota computer claims 53miles-per-gallon (American Gallon).

  • I have not independently verified the gallon usage of my car.

  • 295 miles driven total, sometimes EV, sometimes Gasoline, sometimes both.

  • 30F to 40F (-1C to 4.5C) in my area this past week.

  • Winter-blend fuel.

  • 12.5miles per $electricity-dollar (17.1c / kw-hr home charging costs)

  • 17.1 miles per $gasoline-dollar ($3.10 per gallon last fillup).

If anyone has questions about my tests. The main takeaway is that L1 charging is so low in efficiency that gasoline in my area is cheaper than electricity. Obviously the price of gasoline and electricity varies significantly area-to-area, so feel free to use my numbers to calculate / simulate the costs in your area.

There is also substantial losses of efficiency due to cold weather, that is well acknowledged by the EV community. The Prius Prime (and most other EVs) will turn on a heater to keep the battery conditioned in the winter, spending precious electricity on battery-conditioning rather than miles. Gasoline engines do not have this problem and remain as efficient in the winter.


I originally wrote this post for /c/cars, but I feel like EVs come up often enough here on /c/technology that maybe you all would be interested in my tests as well.
