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?

They became the Government and are using their power to mass fire everyone to get rid of the Deep State.

Why do you think MAGA is so willing and ready to fire huge swaths of the US Government?

/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.

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.

Lex Luthor literally becomes president in many versions of the Superman cartoons.

The idea of a rich billionaire with a narcissist Messiah complex with a bone to pick with heroes and actual helpful people that becomes popular and eventually the US President is practically a trope. Apparently this generation has forgotten the message.

Hey, lots of Political Topics coming up that's just turning into blame games, anger and bad vibes. I'm enacting a temporary rule: no new politic topics for one week as of now.

I recognize that there is a lot of anger around the election and it's legitimate to feel that way. But I'm willing to bet that none of the political talk in the next week constitutes a 'Best Of' post anyway.

That being said: feel free to use this topic (!!!!) as political talking points. I'm serious. People deserve to discuss their opinions and I don't want to hamper them too much.

If you have political stuff to say, say it in here. I'll promise to lightly moderate this topic, which means this topic will naturally lead to bad vibes and poor arguments.

But we need a place to discuss and vent.

Despite all the doom scrolling, Harris has a comfortable lead in the electoral college right now.

The time for vibing is over. It's too late to change anyone's opinions (especially because national level events like debates are over). Harris will finish her Media Blitz soon (including a Fox News showing) while Trump retreats into his shell hoping no one notices how damn stupid his mouth is.

This is the time for doing. The focus should be on voter drives and other get out the vote pushes. It's mid October, and the October surprises are against Trump and in our favor.

It's not the lead we wanted but it's a lead nonetheless. Don't talk yourself out of believing this lead because of a bad poll or two.

Because Threads and BlueSky form effective competition with Twitter.

Also, short form content with just a few sentences per post sucks. It's become obvious. That Twitter was mostly algorithm hype and FOMO.

Mastodon tries to be healthier but I'm not convinced that microblogs in general are that useful, especially to a techie audience who knows RSS and other publishing formats.

Nothing is guaranteed before the election.

And since Jan6th is how Trump left the last election, nothing is guaranteed even if the election wins. But an election victory in massive numbers would be our best bet moving forward. It cannot be close, Trump must be soundly defeated for the country to move forward effectively.

TL;DR: Prius and Prius Prime have a flaw where the rear doors may get water-leak (possibly from a car wash?) and randomly open even while driving. Toyota has issued a large scale recall as well as a stop-selling order to all dealerships.

That basically covers all 5th Gen Prius and Prius Prime vehicles. So until this door issue is fixed, no one is buying that vehicle.

Lemmy, the social network, started off as a leftist hangout spot.

From the perspective of "Open Source developers who are anti-Reddit pro-Fediverse", it makes a lot of sense for Leftist/Communist and anti-corporation leaning people to hang out.

After all, the more extreme the viewpoint, the more driven to action (ie: write tens-of-thousands of lines of code and release for free) people get. In some regards, its the nature of Open Source + volunteer effort to attract a more extreme ideology. IE: Free Software is driven by ideology, not by money. So you get ideological people, especially when the software is small and niche.

The July 2023 Reddit Blackout was a big challenge for Lemmy's old community and the new community, as the new community basically "invaded" a large scale leftist hangout spot. But hopefully we all learn to work together and the nature of our neighbors moving forward.

I think anyone here (likely everyone?) is at least on the anti-corporate anti-Reddit side of the discussion. Which is enough of an alliance to keep us together, for now.


It does mean that we'll have to keep up with the far-left old-timers on this network who wish to push their viewpoints. But they are the legacy and the start of Lemmy in some respects, even as the hypergrowth (starting in July 2023) has moderated the community pretty severely.

I've preferred Pixel phones for the last few years but I've heard that Pixel 6/7 had 5G connection problems (Pixel 8 apparently has a better modem, but I think I'd rather stick to a Qualcomm design for now).

So onto looking for my next phone.

I haven't considered a Samsung smartphone in years because I hated their TouchWiz stuff. But apparently they got rid of that like 8 years ago and have had multiple versions of updates. Can anyone comment on how good "One UI" is compared to stock Android? How much bloatware does it feel like? And what kind of customizations did Samsung do to the UI exactly?

I'm also looking at Asus Zenfone 11, but I figure the "mainstream" choice today is Samsung, so I'll also have to seriously consider Samsung phones.

I didn't realize Baltimore was so important for the car market of the Midwest and East Coast. Apparently 800,000+ cars are delivered per year through the Port of Baltimore, but with the bridge collapse today it sounds like shipments could cause some car market issues for a swath of the country.

ASL is well on its way with some of the best professional Starcraft players duking it out. Just a few days ago (yes, still an active pro-scene!!), this excellent Starcraft game happened.

I don't want to spoil it too much. The above timestamp should take you to the start of the match. Its a bit over 25-minutes long from that point (the 4-hours is for the entire pool / all the matches, not just this Mini vs Barracks match).

All the top-level micro you'd expect from 300+ APM players like Mini and Barracks, with some excellent strategic play ultimately leading to the most raw slugfest of an ending that could possibly happen in Starcraft.

The problem wasn't the glass.

The problem was using wtf touchscreen controls to shift between drive and reverse. Mrs. Chao confused the two then died.

Shitty UI kills another person. Tesla fucking up basic UI design is the real villain here.

AirBnB is just as corporate and lobbyist bullshit as any other company. Arguably worse, in that AirBNB breaks the laws and then tries to get laws changed.

Hotel chains at least try to lobby to change the laws before breaking the rules.

Not that I'm familiar with Rust at all, but... perhaps we need to talk about this.

The only thing that could have prevented this is better moderation tools. And while a lot of the instance admins have been asking for this, it doesn’t seem to be on the developers roadmap for the time being. There are just two full-time developers on this project and they seem to have other priorities. No offense to them but it doesn’t inspire much faith for the future of Lemmy.

Lets be productive. What exactly are the moderation features needed, and what would be easiest to implement into the Lemmy source code? Are you talking about a mass-ban of users from specific instances? A ban of new accounts from instances? Like, what moderation tool exactly is needed here?
