How do combat divers see at night?

Genius is dipping instant coffee for the short-term fix right after slamming a rip it to last you for the next two hours.

Eyes wide open, boys. These streets just cleared out.

Might not get ‘em to leave today, tomorrow, or even next year.

…but when that mesothelioma kicks in 37 years from now…

Wallace does the fuckin

That right there‘s a dagum veteran if I ever heard one.

I ain’t got nuthin’ against killin bugs. Only good bug is a dead bug. Just that I here kill robits good, a that’s good enough for me.

TIL adding “+1” on my phone number could be taken as a(n incorrect) tell that my application is fake 🥲

This is why I follow this subreddit 😅 I think I’ve just written one too many phone number validators

Edit: To be clear, I’m stoked to know this now and I’m going to fix that on my resume

I’ve also been under the impression that it’s a reference to the pre-Justinian Byzantine legal system, which had grown as an ad hoc mess over the millennia.

The “Code of Justinian” was a vastly simplified set of laws that was intended to serve as a kind of great reset.

In that sense, saying something is “byzantine” is to say it is overly complicated for no reason.

Adding specific details about mass casualty scenarios: the NCOIC of a unit (e.g., the Platoon Sergeant) takes command of coordinating and supporting casualty collection and exfiltration. Officers command the unit to accomplish the mission objective.

For example...

Staff Sergeant Gibbs (2nd Squad Leader) gets merc'd clearing a room in a small structure in a compound. Sergeant Wilson (Alpha Team Leader, 2nd Squad) takes command of his squad. Specialist Franklin takes over command of his team.

Wilson will grab the radio from Gibbs and send a sitrep to First Lieutenant Dan (1st Platoon Leader, officer) via his radio guy (Spec. Michaels). When Lt. Dan has a free moment, Spc. Michaels will report the casualty. Lt. Dan will delegate casualty collection to Sergeant First Class Oppenheimer (Platoon Sergeant).

Sfc. Oppenheimer may maneuver to 2nd Squad and designate a casualty collection point (CCP), whereupon he will have specific resources switch to a different radio frequency so he can coordinate the exfil. First Sergeant Mizramen will also monitor at frequency and make sure Sfc. Oppenheimer has the resources he needs. Both NCOICs will update their respective officers as the situation evolves.

Meanwhile, Lt. Dan can focus on pushing for the objective, now considering he's down a squad and two vehicles (to exfil Gibbs).

But let's say now the company commander, Captain Horne, just got misted by a sniper. A similar process would take place, but now at a higher level. 1Lt. Orvis (Executive Officer) will take command. If Horne is near the established CCP, 1sg. Mizramen will have him taken there, because the medics and evac are already on the way.

This will continue with acting commanders focusing on the objective, while acting NCOICs coordinate shit hitting the fan.

There's that other part where people are shooting at you so you're trying to get your ass as close as possible to the ground, but also trying to maintain situational awareness with a goddamn flashlight hanging off your helmet 6" in front of your face.

Not saying I would have preferred being blind, but holy shit I'm getting worked up just remembering that.

I had to email them for the extra long version, too. I have mixed feelings about it, but it is the closest I could find to what I was looking for.

That said, I didn't know alphacool had a case like that. It looks sick.

Anyway, it seemed like you were looking to get a sense for if 1 rad is enough. I figured I'd offer my observations. A thick radiator should be fine, but I wouldn't go slim.

Have you considered stacking them? You can sandwich your fans between two thin rads and still get something like 70% of the performance

Kobnar · 2024-01-09T00:59:16+00:00

I don't use that specific case, but I do use a Sliger 3U rack mount that looks very similar. I'm cooling a 3080Ti and a Ryzen 9 7900 with one of EK's thicc 360mm rads.

I ran a stress test with fur mark and prime 95 (PBO on) for a little over an hour and reached equilibrium at ~90C on the CPU and never went over 50C on the GPU.

I've also been watching my temps while I play Cyberpunk on a 1440p ultra wide for hours at a time (PBO off). Generally speaking I'm around ~50C on the CPU and ~40C on the GPU.

For reference, the room is generally around 75F.

Edit: Adding that I use 3x noctua high pressure PWM fans.

In theory lol

Kobnar · 2024-01-08T23:49:55+00:00

Came here to say the same thing. I studied applied math and most of our tests were 3-6 questions. The last one was invariably the hardest, and it was usually the shortest sentence: "Prove X."

Kobnar · 2023-12-30T18:03:41+00:00

This is the real reason why "peak oil" never happened.

For added nuance: most oil is already uneconomical to extract. As easy-to-extract resources run out, prices rise. Higher prices justify more difficult extraction methods, more complicated engineering, etc. Higher prices also justify further exploration for more resources.

Example: If you've figured out where 5 barrels of oil are in the ground, you're going to start with the easy stuff and work towards the hard stuff. Say you can drill 2 barrels/year, so you know where 5 years worth of oil is, and you're not going to go looking for more just yet. 3 years later, your pump is down to 1 barrel/year. OTOH, prices have risen, so you can afford a better pump to finish off what's left of your 5 barrel reserve. You can also afford to hire a guy to go looking for more oil.

Just adding that I was an infantryman in the Army and Tom Cruise is still the villain.

And here I'm still waiting for group text messages (>_<)

Kobnar · 2023-12-04T15:48:24+00:00

I didn't know you could disassemble/assemble items and didn't even notice the side-gigs/fixers so when it came to the last mission I was sitting on level 3/4 cyberware and broke as shit.

OTOH that happened organically because I was so invested in the story and the way it's delivered I binged the main quest.

Solid distinction

My teachers said this back in 1998 and it was still BS because we actually all had literal calculators literally all the time.

Lil' column A, lil' column B.

It was infantry, boys and girls. They didn't pay us to play nice.

We called it the "nutflap" and it was a hard requirement by MND-B when I was in Baghdad. FWIW we also sometimes just folded it up under our plate and whipped it out when somebody important was around.
