I thought they stopped selling children at Walmart

Many cars have this with the touch screen, sport mode, eco mode, etc. Some will even learn from your driving behaviour and calibrate to that.

The change is functionally instant, and when the original post talked about mapping it’s really a bunch of graphs and curves that dictate behaviour over the full range of rpm of the engine. You can switch maps on the fly by loading different basically spread sheets into the computer. Factory cars are calibrated for general use and epa standards, but you could make all kinds of special settings for various conditions.

My knowledge of this is dated, haven’t been in the industry since 2000, but the basics haven’t changed.

Older Porsches had a physical button on the floor under the gas pedal that you’d trigger when you floored it, putting it in spaz mode.

The truth is, how you drive has a bigger impact on fuel efficiency than anything else, don’t accelerate aggressively, and stay below 65 mph. Wind drag above 50 mph is by far the greatest impact on fuel efficiency. Internal combustion engines are generally most efficient between 1800 and 2500 rpm, so if you keep your cruising speed there you’ll get the longest range on road trips, but obviously it’ll take that much longer.

It can’t do both at the same time.

By remapping I assume you mean changing the ECU (engine control unit) programming.

Depending on what all it controls, usually fuel injectors and ignition, and what it reads, air pressure, rpm, oxygen, throttle input, the mapping adjusts timing of ignition, and how much fuel is injected based on how fast the engine is spinning, and where the throttle is set.

Most cars from the factory have a very simple mapping based around what most drivers do.

A fancy prototype CRX I had back in the 90s had very custom mapping that meant when I drove mellow, it got about 45 mpg, but had very slow acceleration. If I pushed the throttle past a certian point, it spun up like a bat out of hell, but the fuel economy would plummet.

What you can do with custom mapping is change the way the engine behaves under various conditions and based on the inputs. There is no magic get more out of the engine. Want more power? Eat more fuel and lose economy, and likely not burn off all the fuel so more dirty exhaust. Want more range? Limit power and lose acceleration.

Have had my S8 galaxy since release, and now various apps won’t work on the OS. I’m being forced into buying a new phone at this point.

I’ve gotten it in two flavors.

One is people who are so convinced that life has no meaning without children they feel like they are saving you by pressuring you to have kids.

The other, and far more angry, seem to have had kids because they thought they had too, or had a “happy accident”, and aren’t actually happy about. They see you as the life they could have had.

I have a few times in life, but I’ve always found a new one.

Each time I’d get deep enough into something, tech advancements always made that thing functionally obsolete.

Once again I’m watching my skill set being phased out, but am working on my big last hurrah project right now that I’ve dreamed of for years. Having a great time doing it, but have already started the process of replacing it over the next 18 months.

The one plus side now is that the company I’m with has already invested in my training for the next big thing. I’ve been through it enough times that I don’t feel like I’m losing something or wasted my time.

This is my solution. I’ve said it before, but think it should be repeated. The global population was half of today’s when I was born. 4 billion instead of the current 8+ billion.

That means if half the population disappeared today, we’d just be back where we were in 1975.

Not having kids is the best thing I can do for both the environment, and myself.

Has the added benifit of leaving me as a passive observer who doesn’t have a biological need to care about the future.

This was my first thought, one of my favorite series.

I went into one of the larger local shops to buy some risers or something to try and adjust my old setup. Older sales guy about my age took one look at my gear and said “Your knees must hurt like hell”.

I had the money, so I just went full in on new gear, and came away with something I would never have picked for myself.

Not only did he size everything proper for me, he made sure all the pieces were right together. For the first time in my life toe and heel line up exactly with the edge, and where they belong on the pressure points. I’d always riden too small a board and had far too wide a stance to make up for it.

I was still skeptical, but he told me if I didn’t love it he’d do a full price exchange.

Even though it’s about the longest board I’ve ever had, the banana camber makes it feel half the size. Took about three runs to actually trust the board, and I was completely sold, you couldn’t pay me to ride the old gear again.

True, but at least where I ride they have 100% snow making covered. Solution to man made warning is man made snow.

Joking aside, the season in the midwest sure has shrunk since I was a kid.

It’s like going from moms station wagon to a high end sports car. Do I need the performance sports car? Usually no, but those few times you push it, it’s ready for all that and more.

Thermal form boots are a must, though I guess that tech is more than 15 years old in ski boots at least. I no longer cringe and grunt when I put on my boots, they are as comfortable as any footwear I’ve owned.

The flexibility in modern plastics means the straps and bindings themselves are stiffer where they need to be, and have give where they don’t. Combined with the boots there are no more pinch points at all, and all the force you put into riding goes where you want it.

I ride almost exclusively in the midwest US, so hard, rough, icy conditions that most people wouldn’t consider snowboarding in are the every day. A board with reverse camber, often called banana, and magna tractions, serrated edges for holding grip on ice, are a must.

“Turns ice into powder”, well I dont know if I’d go that far. I can lay into turns in the worst conditions and completely trust the edge to hold. When you get that horrible downhill edge that wants to catch and slam you into the ground, the newer complex curves in the camber means more often than not you will pivot out instead of hanging up. I can’t count the number of times I’ve felt that edge wanting to catch and end my day, only to slip around switch and get away with it.

I’m sure there are more now, but a product called 3DO gel was the first I saw. Flexible and soft normally, it turns ridged under force. I have pads of that stuff basically all over my body, knee and elbow pads, but also tail bone, forearms, and in the liner of the helmet. Saw a demo where they were hitting a guy with a shovel and instantly thought “That’s for me”.

If I had to pick one, a board with C2 or C3 gen camber from lib tech, or its equivalent makes the biggest difference. The over all package of a new setup bought and sized together for my cough, um, “modern” weight requirements, took riding from a painful and nervous experience, and made it relaxed and enjoyable again. Due to many old injuries, I used to ride an hour, maybe two, and had to quit. Now I can ride a full evening, and feel good about doing a few hours the next day as well.

The advances in material science and manufacturing in sports equipment in the past 15 years has been amazing.

That means boots, bindings, and a snowboard that would have seemed like alien technology to me when I started riding. Same goes for all the saftey gear, knee pads, helmets, integrated wrist guards in gloves.

The performance, comfort, and saftey offered by modern equipement means I can still enjoy my favorite sports at 50. The thought of getting on a hill with gear I had just 15 years ago makes me shudder.

My earliest gaming memory is my dad taking me to a local hotel bar to play Pac-Man when it came out, which suggests spring of 1980.

I know I played pong, river raid, and pitfall on home consoles as well, not sure which was first.

One xmass we got an Atari, but when my dad realized it came with a poker game he returned it a few days later.

First system I had actual private access to was a TRS-80.

No, I don’t think that would work for me.

I’ve had this handle since '94, and I am not letting any of this bother me.

Others have said it better than I can, but how you see yourself as weird, and why it bothers the politicians it does, are not the same thing.

They live in a different world where conformity is king and being different is scorned.

Don’t let it ruffle you, none of this has anything at all to do with you, how you live your life, or how you perceive yourself.

Mass Effect and Dark Souls are my favorites when it comes to gaming.

I just don’t fall that way on a skateboard, so I never wear one, though knee pads are a must.

I will never ever ride a snowboard without a helmet. I’ll ride a motorcycle without a helmet before I’ll ride a snowboard without one.

If you don’t feel it, don’t do it. Some injuries don’t heal right, and many of the hobbies I enjoy have a pretty damned high risk factor. Almost every single time I’ve had a serious injury, that little voice was telling me “This one might not end well”, and I went for it anyway.

I could have walked away, called it a day, and come back another time. It wasn’t a contest, I was just out filming a few tricks for my “You’re turning 40 and still doing it” video. Didn’t stretch, didn’t warm up, and my over enthusiastic filmer was all “Try this, do that”. Ended up collapsing my knee and fully tearing my MCL.

Between that and a few neck and back fractures over the years, my mobility and flexibility are pretty well shot. There are things I just can’t do anymore.

Sure I still skate, and am amazed just how much I can still get away with, but now every minute on the board includes a constant “Is this safe? Is this worth it?” chant.

No, I will. The whole thing fascinates me but it’s the technology that really gets me.

The combination of high end tech and seat of the pants old school exploration ingenuity is amazing.

When we left earth, a multi part history of the space program.
