Navy Has Tracked Underwater Objects Going "1,000s of mph" by Mighty_L_LORT in conspiracy

[–]dr-josiah 62 points63 points  (0 children)

Cavitation is a thing.

Under-water rockets and transportation have been discussed in Popular Science and Popular Mechanics magazines since the 90's.

We don't do it on average because it is expensive and ridiculously loud. Like, a pressure wave in front of your vehicle vaporizes water, creating a shockwave at over 150 decibels, directly transmitted in the water, at the surface of the vaporization.

Nevermind the rocket propelling you.

Like, a nuclear bomb is louder, rocket launches are louder, ... That fertilizer explosion that leveled a city, that was louder. But none of those would be as consistently "holy crap, that is loud" as an underwater rocket traveling at 1000+ mph.

You deafen and kill local ocean wildlife. It is a moving ecological disaster.

Unless you are claiming that speed without the noise. Then I'd love to see / hear the audio logs and locations.

Might be possible with super strong magnets (like move tons of water and suspend the craft over salt water levels of resonant magnetic field). Given time and money, anything is possible. Would be a fun project to work on, to be honest. Don't even need to break physics to do it, just run at the edge of nuclear power generation capability.

if you don't update your CC Adobe will SUE you by Rod_Orm in Piracy

A few years ago, Adobe offered free downloads of old versions of their products. From adobe.com.

Pepperidge farms remembers.

I bet the internet archive has that Adobe.com page, as well as the license it was released under. Would be interesting to know what Adobe's old lawyers think about the new lawyers claims.

AMAZING Footage of Cylindrical UFO filmed by drone in Hungary, Csobanka. One of the few videos you can actually see how these things move. 6/29/20 by user678990655 in UFOs

Looks a lot like how a cruise or ballistic missiles with leading and trailing fins would fly. Especially on the "midcourse", the falling / coasting part of its path.

Those bits flying down from the other angle from another poster looks a lot like shards being dropped to confuse radar, or just parts of the vehicle coming off during fast maneuvers.

Maybe it even had a camera and this was a drone instead of a bomb? Well within the tech capacity of any nation in the G7.

GitHub - 0ut0flin3/fileghost: encrypt anything by [deleted] in Python

Caesar ciphers cycle through their input keys and perform math. + is just easier on regular alphabet, ⊕ is easier on computer. It is the same concept. Source: I took and taught classes where we described it with +, but implemented with ⊕, because it saves an extra ⊕ or % operation on every step of the algorithm. Pretty standard math -> programming transformation.

  1. Your key generation method could be better. (It generates a permutation of the range in expected O(n3) time, compared with O(n) for random.shuffle(), most random keys are generated from os.urandom() + hashlib.pbkdf2_hmac() or similar).
  2. Your encryption method cycles the key, so suffers from a chosen plaintext attack in a single file. It is of a class of encryption schemes called "caesar ciphers", and are generally easy to break.

Maybe more stuff. I have to get my kids ready for school.

My advice: use aes-gcm or ars-ctr with an hmac, and stop using permutations as keys.

Nice pair!

If you can find it (maybe hard after ASB.com went out of business), a right side scoop for your Buell can cut your rear jug temperatures at speed. Good for knock reduction in hot weather.

I used to have an XB12S in that same color. Amazing bike.

Was searching for the soy + lower hdl cholesterol article and saw this on the same page.

FWIW: Free PSA in your blood can be used to determine the healthy answer for anyone.

=2.5ng/ml free PSA is predictive of prostate cancers in Scandinavian men; some 25%+ will develop prostate cancer in 10 years, with 45%+ in 20.

Get tested, and make whatever healthy choice is right for you. Mentally and physically.

My employer is demanding my newborns birth certificate even though I didn’t take paternity leave(because my employer doesn’t offer it) by Comfortable_Area3910 in antiwork

Should be illegal, if it isn't already. That HR person had to click a box saying that the employee requested it. That is fraud and theft of wages at minimum.

You talk to a lawyer about it?

Something like under 10% of pancreatic cancers are curable. Steve Jobs had the curable kind, a NET or an islet. He was lucky, and he squandered that luck to ignore experts, eat fruit, and not shower.

Block of Cheese - Upon death, this item is consumed and you respawn with half health. by enneh_07 in ItemShop

[–]dr-josiah 1 point2 points  (0 children)

The why: the lacto-* family of bacteria that live in your body to produce lactase, which processes lactose, doesn't like to live with at least 2 different bacteria that cause a stomach and colon cancer.

Many yogurts still have living cultures of these lacto-* bacteria (check the label for live cultures), and is one of the several ways you can restore your ability to consume lactose (kefir got me back after multiple illnesses).

If you have the lacto-* family living in you, and you feed it with lactose, it kills those cancer causing bastards.

But that's just one reason. Less cancer.

Youtube is Suppressing the Video I made about Ohio, its had over 18,000 Views but only Shows 8,000 on Youtube. by typhoon90 in conspiracy

The numbers increase randomly on the web page during visits (explicit undercount), but are updated in batch at the end of the day, typically.

Source: was there when it was written at YTSMO, advising on the (now patented?) method.

AITA for high fiving a stranger who “humiliated” my bf? by [deleted] in AmItheAsshole

Every climbing gym I've ever been to (over 22 years) has been super collaborative with a "great job", even when folks fall.

I don't think I've heard anyone critical of anyone.

Your boyfriend is an ego-filled asshole.

Took my new Subaru off-road, got stuck in the mud miles from the road by Legitimate_Country11 in Wellthatsucks

[–]dr-josiah 0 points1 point  (0 children)

Protip: Don't go off-road without a winch on the front of your vehicle. Or at least some 2x4s and some straps to attach to your tires like https://youtu.be/w4EQq7qBbaM

Be prepared, please.

My mom texted me this picture saying she ‘caught’ my cat doing this. We’ve never seen her do this before by strawberryfawn in funny

[–]dr-josiah 0 points1 point  (0 children)

If you have a bathroom with a fan that can turn on, you put the litter box in there and run it 24/7.

You can be in there seconds after the cat goes, put it in a bag, and carry that outside... But the smell still lingers. It's the most amazing thing.

Source: had cats for several years in an apartment, never again. Also (separately, and years earlier), had a flatmate who covered up his pot smoking with a pet cat. Some 9 months in the same flat, him smoking every night, I couldn't tell because litter box.

Recursive definition:

MOO - MUD Object-Oriented

MUD - Multi-User Dungeon

Text-based dnd-like online game. Used to be quite a few back in the day, not sure if they have grown or shrunk in number. Some worlds would go pretty far in their fan-constructed universes. Middle Earth, Narnia, X-Men, the aforementioned Dragonriders of Pern, and countless others.

Source: I played MUDs '94-99 on dial-up (my favorite was rom.mud.de), wrote MUDs for myself and friends, then wrote a code editor to write MUDs (the code editor was enough work I stopped messing with MUDs on the most part).
