Had this bite me once growing up. Forgot to get an ad block on my friends PC and ended up blasting porn ads on the family PC.

Is there a change log anywhere?

IPv6 huh? There are dozens of us!

You either die a hero, or live long enough to see yourself become the villain.

Turns out the biggest bug of all was keeping the default password.

Tonight we investigate the hacker known as 4chan. More at 9.

Yeah you’re right; looking it up it was 3. My kid brain at the time must have seen that and the tale of the multiple disks grew.

My buddy had this game, shit had like 8 discs

At least that’s an easy one, you just convince them to delete their account. \s

Bought a Vizio cause it was cheap. Ended up seeing vertical lines just outside of the warranty window.

You get what you pay for. Now I have a Sony, and no looking back

Personally I’d go for an aqueduct type system

I don’t get to set stuff on fire as much as I did in grad school, but I still get to do it occasionally (typically cost, safety, time, etc limitations). I got a degree in mechanical engineering then stayed on to do experimental fire research on lithium ion batteries. Now I help design battery packs that can withstand single cell failures without blowing up completely. Basically I keep a small fire from turning into a big fire. The main trade off is mass/volume of the battery pack, but the latest tech is getting really good in terms of performance.

In grad school, I would’ve tested the hell out of all my ideas. Now, my time is worth something and I have to be smarter about it. Typically model/simulate several ideas, optimize the best of those ideas, then test the best ideas based on preliminary simulation results. Iterate based on test results and so on.

I should also clarify when I say burn, I mean strap an electrical heater to a battery and observe the response. Heater is meant to represent an internal cell short circuit failure (which is typically cited as leading reason for thermal runaway outside of bad/defective battery design)

This is the best comment in this thread. Imo a better option is not to change the cooling fluid, but to have a water connection that allows firefighters to flood the battery instead of just spraying on the vehicle

FYI Lithium and Lithium-ion are two DIFFERENT battery chemistries entirely. Lithium batteries are primary type cells, meaning not rechargeable (there are some secondary/rechargeable in work currently, but not common yet). You don’t want to put water on a lithium battery due to the lithium metal. However, you typically only find lithium batteries in coin cells (think your watch/fob battery), so big fires are extremely unlikely.

Lithium-ion is a separate chemistry that is a secondary, or rechargeable, type cell. Because the lithium is bonded to a metal oxide (Co-O2, FePO4, NMCO, etc), the lithium is stable and water can be used.

In any case, it’s difficult to use water for EVs because they’re designed to be watertight, so you’re trying to put out a self-sustaining fire/chemical reaction that’s in a box in a box inside several dispersed cells.

This is not an electrical fire, as there’s no sustained voltage. Once the cell fuse pops, you’re only dealing with a single cell internal voltage of 4V (for lithium ion).

I’ve personally burned LFP cells in an inert nitrogen pressure vessel and they very much do burn. They’re “better” than more reactive chemistries like NCA and NMC, but they do still burn (see story of burning teslas). That battery compartment likely has very little air in it, due to the large volume of gas vented during thermal runaway.

Let me know if you have any questions.

These batteries are 101% efficient.

+1 for CS50. This is where I started and I’ve since transitioned to python. I think the basics will make you a better programmer overall (instead of python first), but it really depends on what you’re looking for.
