Doom WASN'T 3D! - Digressing and Sidequesting

jimnms says...

Monsters in Doom didn't really fly. All characters extended from the floor to the ceiling even if they didn't look like it. If you tried walking under one of the "flying" monsters, you would run into an invisible wall. This was also noticeable in multiplayer. I remember playing deathmatch with a friend and when he went up an elevator to grab a power up, I ran and sat at the bottom of the elevator waiting to surprise him when he jumped down. He couldn't jump down, because my character was blocking him even though he couldn't see me down at the bottom of the elevator.

Doom's levels, as far as the computer was concerned, were still a flat sheet of paper, and the player and monsters were just little 2D sprites moving on top of the paper.

Jinx: Wolfenstein 3D did not have a Z coordinate, in Doom one could set floor and ceiling height and specify how far down/up the walls should extend. Players and monsters would then correctly follow the floor level (or fly).

Harrison Ford is The Ocean

MilkmanDan says...

"I covered this entire planet once."

I didn't know that and doubted it, so I googled. Link says that before around 1 billion years ago, water (ocean) covered 95% of the surface of the earth, and then continents erupted relatively quickly, geologically speaking.

However, I think that 95% coverage figure (and possibly more earlier on?) would mostly be owed to the crust and mantle being relatively flat and smooth after cooling down from being a largely molten ball very early on. Now that the earth has cooled enough to allow plate tectonics to push stuff around and create subduction zones and mountain ranges, there are too many high-elevation points (and low elevation chasms for the ocean to fill in) for the ocean to ever cover the entire earth again. Even if all of the ice on the earth melted, apparently sea level would only rise by about 70 meters / 230 feet.

So the "and I can always cover it again" bit at the end is a bit overstated. We'd almost certainly be dead as a species if conditions were extreme enough to melt all of the ice around the world, but not because of being drowned off of dry land to live on.

Pig vs Cookie

transmorpher says...

I hope you don't feel like that I'm pushing anything onto you. I'd like to just present the facts. I wasn't vegan until I turned 33, so I'm certainly not judging or trying to give out this information in order to put anyone down or elevate myself. I'm not trying to troll, I'm not trying to out-do you. I'm also typing this with limited time, so apologies if some of it sounds frank. (The videos below do a better job than me anyway).

1) A proper plant based diet makes it 8 times less likely for cancer cells to grow. There is a reason why 3rd world countries (that have largely plant based diets due to poverty) don't get cancers us westerners have. Also the #1 killer in the western world is cardiovascular disease, in the US alone one person dies every 8 seconds from it. Which is around 400, 000 people a year.

I know you're sceptical. I was too. So here's some actual science from actual doctors, who have come these conclusions on proper peer reviewed and non biased / industry funded research:

2)Vegans aren't anti-choice, they are pro life, pro planet. The actions of people eating animal products goes way further than a person choosing to eat something(sure they are typically ignorant of the consequences, as most of pre-vegans were too). When a large portion of the planet chooses to eat animal products it effects everyone, because it's destroying the planet through global warming, deforestation, dumping of animal agriculture waste and so on. It kills more animals than just ones being brutalised in cages. It will eventually kill us too. To me it seems like a bad idea to destroy the only place in the universe that we can currently live.
So by eating animal products you're really making a choice for you, for me, for my hypothetical grandchildren, and of course for the animal that almost certainly wants to keep being alive. So as a vegan I'd like you refrain for making choices that impact my life, and I'm standing up for the voiceless animals who would certainly object to your choice too.

3) As you (hopefully) saw in at least one of the videos above, there is nothing in meat which cannot be obtained from a plant source (and without all of the bad stuff that comes with meat).



Your idea of a farm with humanely raised animals is a good start, but it's just not practical, the earth isn't big enough to meet demand. It's also still highly unethical as you still kill the animals at an early age in order to harvest their flesh.

You have a picture of two dogs in your avatar. I'm sure if someone decided to schedule their lives to end early for any reason, let alone to eat them, you'd find that pretty immoral right? You no doubt treat your dogs very well, but that doesn't make it OK to kill when they reach adolescence. If I said I wanted to eat your dogs (I don't of course) then any reason you came up with applies still to any farm animals that you currently feel fine with eating.

The animals also aren't stupid and they're aware of what's going on. My grandparents owned a massive farm with cows/pigs/rabbits/chickens and crops as well. They were living very comfortable lives as far as farm animals go, but they did not like it when you approached them, they knew what was waiting for them.
When you see typical farm animals that are truly free this is what they look like: https://www.youtube.com/watch?v=kIF3BYBXZWA
They behave like pets, even cows kick a ball around.

Also cows milk is only created for when the cow is pregnant. Even if the cow is living in cow utopia, if it is getting milked then that's milk that should have gone to a calf. It was most likely artificially impregnated, and also most likely bought from someone that breeds female cows, and kills the male cows (since you only need one bull to harvest the semen).
When you really think about it, even the best treated animals are being breed and used to make someone money as the primary goal. That is immoral.



So what it really comes down to is taste. The ethics, the environmentalism, the health don't play a role in the debate at all, and hopefully one of those things is important to you, perhaps all 3.

Being animal product free isn't as hard as you think, it's as simple as swapping out a few ingredients here and there. It's not all about eating broccoli and kale. You'll still be eating burritos, burgers, pizzas, pastas, curries etc. Just slightly different and before you know it, you'll barely know the difference, and eventually prefer them that way.

And this is probably the part I found the hardest to believe myself, but once I knew about it, veganism became the easiest thing in the world. Taste is completely influenced by the foods you eat, because of brain chemistry. I thought I could never stop eating two things: cheese and chocolate. After about a month of not eating them (and yes it takes a little bit of effort towards the 3 week mark) you will break the dopamine effect in your brain and you'll never want to eat them again. I can eat vegan cheese and dairy free chocolate, but it does absolutely nothing for me these days. This is coming from someone that wouldn't eat regular chocolate, I had to have the good stuff, everyday. The cravings get pretty intense at the 3 week mark, I won't lie, but then one day you realise you've not had the cravings for several days.
When it comes to meats, even if they are well done, all I can smell is oil and blood. Eggs all I smell is sulphur. I find all of that quite repugnant and I see them for what they really are, rather than what my dopamine recepters tell me.

Now of course you can be unhealthy vegan, and eat all of the oreos, chips, and dairy free chocolate you want. That's up to you, either way the planet and animals don't care which way you go about it

My 2 cents....

1) Don't EVER get your science just from the internet. ALWAYS verify anything you think you've learned with published peer reviewed science publications/articles.
Veganism does NOT cure or inoculate against cancer (which I'm assuming is what you mean by the #1 killer in the western world). If it did, that would be headline news and easy to prove, since vegans would all be cancer free, they're not. That's some serious BS right there. It may be HELPFUL against heart disease, I'll grant you that much. If that's what you meant, ignore the above.
If the point is eating healthier, excluding processed foods is exponentially better than excluding meats, and should be the first step people take when changing their diet, long before excluding meats all together.

2)So now Vegans are just like anti-choice people who think their choice should be the only choice for everyone!? I hate to tell you, but that position will make your movement lose, no question. Your position leads to only one logical conclusion, attempting to force people to stop eating meat. You don't change minds by force. I suggest you try a seriously different tact, or I fear you're methods may destroy your movement.

3)There is NO "better" alternative to meat. There may be alternatives, but they are not "better" nutritionally. The energy humans gain from eating meat is why we have the brain that allows you to take those positions, plants simply don't offer than dense nutritional value. True enough, evolution is barely still in effect for humans, but that's no reason to stop feeding your body/brain.

Personally, I can see no rational reason to stop eating meat except for moral or health reasons, and if you eat meat raised properly and morally, those moral reasons no longer exist. As we've discussed before, meat from small, local farms rather than large factory farms is often raised with love and care, so there's no abuse, only a scheduled end to life. I have no moral objection to that (and have a hard time seeing how others might have a reasonable objection to it) so I'll continue to eat meat, but I do make an effort to eat only morally raised meats. When the odd occasion happens when I can't choose the meats I prefer, I do feel somewhat guilty, but not enough to go pure vegetarian, certainly not vegan. (which reminds me, all dairy is not produced immorally either. Some smaller farms still exist that treat their cattle with care, but they are sadly disappearing as people usually only buy factory farmed dairy as well, it's far cheaper).
For those who eat so much meat that it's a health issue (yes, I do agree that it causes many health issues if you eat too much), I'm right there with you saying they should eat way less, or none, until they get their health under control.

Why Are Aeroplane Wings Angled Backwards?

radx says...

About the X-1 being the first manned vehicle to break the sound barrier: there are records of Bf 109Fs surpassing 950km/h TAS in a dive when they tried to solve the issue of elevator and aileron lock-ups at very high speeds. I wouldn't call it far-fetched to assume that both G10 and K4 could surpass Mach 1 in a high-altitude dive without the wings shearing off. Alas, no proof. Just an interesting bit of aviation.

What If We Killed All the Mosquitoes?

dag says...

Comment hidden because you are ignoring dag. (show it anyway)

Then, we'll finally have true empathy, as we feel the pain of others like it's our own. We'll turn our collective mind to the true work of man, build a space elevator and begin colonising the galaxy.

Elevator's Revenge-Instant Karma

Elevator's Revenge-Instant Karma

artician jokingly says...

But you didn't hear what that elevator said to him...

Also, look at the form on that kick. That guy's fought a few doors in his day.

Also... something about that kids body language immediately after it happens just seems to say "... again?"

If you had a fear of elevators before...

Payback says...

That's why I'd prefer to live in a walk up or a building short enough to be serviced by a hydraulic elevator. The ones on top of a long hydraulic ram like on a backhoe. They can fail, but all that happens is you slowly sink into the basement.

Dag might not like that though...

WaterDweller said:

May not be common knowledge, but elevators actually have a counterweight, that weighs as much as the elevator would when it's filled by a certain number of people, to ease the load on the motor. When there's only one person in the elevator, the motor actually has to work harder when the elevator is on the way down than on the way up, as it has to lift the counterweight.

When I was a kid I believed that if I was alone on an elevator it would go straight to hell. So I always got off when the last person got off, no matter the floor. Not a fan of elevators.

Why the suspended monorail failed

newtboy says...

He listed at least one reason, that because they are often single track systems, a single breakdown freezes the entire system.

Once it's assumed that it's not reliable or, worse, that there's a decent chance of being stuck in a suspended/elevated train until the whole system can be evacuated (requiring specialized rescue from every train that didn't stop in a station, then being 'down' until the breakdown is fixed or removed), people won't use it, and it will fail.

That doesn't explain why they don't just make all systems 2 track systems like the German one to solve that issue for a bit more money (but not double the money), but it does explain why some failed. It seems to me that they could still be a decent solution in some congested areas where light rail only adds to congestion, and they look neat.

mxxcon said:

Still doesn't explain why they fail.
He listed the alternatives not to build one in the first place, but if one is built, why it fails?

The Incredible Transforming Osprey

Drachen_Jager says...

Yeah, these things are death traps. They're so useless, the Navy has to send out OTHER helicopters to pre-scout landing zones for the Ospreys. Aside from that, the downblast from the rotors is so powerful, it makes work on a flight deck impossible during takeoffs and landings, as an added bonus, it also makes rappelling so dangerous Marines call it the "elevator of death".

Add to that the enormous cost of $72 million a unit a flight-speed too fast for escort helicopters and too slow for escort jets and a host of other problems and you have a very expensive and cool looking lawn ornament. 35 Billion dollars well-spent, Pentagon.
