A quadratic function is just one possible polynomial. They’re also not really related to big-O complexity, where you mostly just care about what the highest exponent is: O(n^2) vs O(n^3).

For most short programs it’s fairly easy to determine the complexity. Just count how many nested loops you have. If there’s no loops, it’s probably O(1) unless you’re calling other functions that hide the complexity.

If there’s one loop that runs N times, it’s O(n), and if you have a nested loop, it’s likely O(n^2).

You throw out any constant-time portion, so your function’s actual runtime might be the polynomial: 5n^3 + 2n^2 + 6n + 20. But the big-O notation would simply be O(n^3) in that case.

I’m simplifying a little, but that’s the overview. I think a lot of people just memorize that certain algorithms have a certain complexity, like binary search being O(log n) for example.

This is the true “We did it Reddit” moment.

Just useful enough to become incredibly dangerous to anyone who doesn’t know what they’re doing. Isn’t it great?

Basically every car says not to wash in direct sunlight. From my understanding it’s because you’ll end up with water spots and other residue from the soap drying on to the paint before you can rinse it off.

If you remember what battery powertools were like in early 2010s, it’s super obvious how far we’ve come. The higher end things like battery powered lawn mowers didn’t exist, and if you wanted real power, you needed a cord.

I guess everything I’ve been calling light rail fits into the suburban rail category. Multiple cities I’ve lived in are adding in “light rail” tracks between major centers

Logic and reasoning were never on the table unfortunately.

Am I the only one left writing pure JS webpages? I swear for the stuff I’ve done recently, adding React or even jQuery makes things 10x more complicated and bloated. The base JS support browsers have now is actually great. It’s not like the old days trying to support every browser back to IE6

I learned this in highschool when I discovered sending ping floods from a 1gbit VPS to a slow residential Internet connection can take down your Internet even if the router doesn’t respond to pings. The bandwidth still all needs to make it to the router in your house to be dropped.

Unless you’re rebasing or something, you should never need --force. It’s a good way to accidentally delete or overwrite a remote branch.

I usually use the +syntax for force-pushing a specific branch: git push origin +my_branch

The risk of me getting wrongfully convicted of something and getting a death sentence is higher than the chance of some dangerous murder escaping prison and hurting me.

Unfortunately being absolutely 100% certain is not a luxury we have in the majority of cases. People are framed, new evidence comes up, things like lie detectors and blood splatter analysis turn out to be junk science. Life in prison can get overturned and corrected if mistakes were made, death can’t.

This graph actually shows a little more about what’s happening with the randomness or “temperature” of the LLM.
It’s actually predicting the probability of every word (token) it knows of coming next, all at once.
The temperature then says how random it should be when picking from that list of probable next words. A temperature of 0 means it always picks the most likely next word, which in this case ends up being 42.
As the temperature increases, it gets more random (but you can see it still isn’t a perfect random distribution with a higher temperature value)

I’m on a prepaid plan, and got in on a really good deal. They were offering $25/month off indefinitely for signing up for auto-pay (Basically 35% off, lol). It made the plan cheaper and better than most of their monthly plans. I’m happy to know it also saved me from giving out my SSN.

To be fair, it only needs to cover the phone’s average power draw if you put in a supercapacitor or small conventional battery.

But there’s another problem… if I understand how this works correctly, for a 1W battery, the radioactive element must be outputting AT LEAST 1W of radiation energy at all times, whether it’s being consumed as electricity or not. Ideally that’s all trapped inside as heat in a best case scenario, but having to cool your battery while it’s not in use is kind of a deal breaker for anything more than milliwatts (or it will have to have a heatsink as big as the battery)

That screenshot is old enough to drink. Do people actually still use teletext?

Just wait 'til you try this knob!

Maps? Android Auto / CarPlay? Gotta have the screen anyway for the mandatory backup camera.

We can have both! Physical buttons for everything that doesn’t actually benefit from having a display, (like music or heat/ac), touch screen for the rest.

That’s a thing? Holy shit… And here I thought the worst offender was Tesla’s yolk steering wheel with a capacitive touch horn “button”.

I went out of my way to find a keyboard with Cherry MX Clear switches. They’re basically a high-force tactile feel, but no clicky sound like MX Blue switches. I absolutely love them for typing, and I’ve been using them for years.

I’m not sure if there’s newer options now for silent switches? I know they had a couple models with extra internal damping.

I think they’re getting at the fact this design would generate massive amounts of torque steer. With the motor input vertical, any rotation will also try and change your steering direction.
