I don't know if this will help anyone here but I've been experiencing numbness of my hands and feet starting about 15 minutes into a ride when it's hot and humid for a number of years. This is partially a result of dehydration from sweating, although the hand numbness is 90% carpal tunnel...

That looks like a car I might have designed. Turbine engines suck when directly connected to the wheels via a conventional transmission. The way the C-X75 uses them (to recharge a battery which in turn drives electric motors) is exactly the best way to use them. This is a case where modern motor...

Building myself a faired recumbent from scratch would be one of my dreams. I don't know if I could improve much on the aerodynamics, but I would certainly like to try. If you ever move beyond the planning stage, be sure to post pictures.

If those were the only two criteria all cars would be using turbine engines.

You're a car hobbyist. Nothing wrong with that. My brother falls into the same camp, just he's not flush enough to buy new cars as often as he might like. Actually, he says his Mark VIII has better fit and finish, and is nicer to drive, than many newer cars. Not surprising given that it was $42K...

It's pretty much the same with everything. I've even noticed it with cycling. An upgrade from a 105 to an Ultegra gruppo is usually worth the price in terms of added functionality. Even a 105 gruppo is just fine for many riders. To go from Ultegra to Dura-Ace is a huge price jump for minor...

That ride seems pretty respectable to me also. You averaged 14.9 mph in spite of the climbing and the wind. I hear you on the wind. Despite Chicago being called the windy city, the average wind speeds in NYC are higher. Yesterday towards the end of the ride there was easily steady winds of at...

I have a rear blinker (modded with a red power LED to be visible from at least 1/4 mile), and a fairly bright front headlight ( ~150 lumens). I have a ~1800 lumen headlight of my own design which I'll eventually be using as soon as I have time to finish it. Blinking lights are fine in the rear...

Yes, I think that's it. My sister is driving a 10+ year old Elantra with about 170K on it. My brother is using a 1993 Mark VIII with 240K. Neither could afford even a low-end new car at this point, never mind one of the cars in this thread.

Man, what I would give for 11°C temps right now. We're having a heat wave all week with highs in the 90s F. Rode at 3 AM last night. I was still warm ( ~23°C,73°F) and 100% humidity. I was plastered with sweat after 15 minutes. Surprisingly, I last nearly an hour and a half. It's going to be...

I think it's just a case of "boys and their toys" rather than practicality. For strict practicality and low operating costs nothing beats some kind of electric vehicle like a Leaf, or one of the low-end Teslas. If more people bought electrics, there wouldn't even be a price premium over gas...

Actually, sub 30 second 1/4 mile times under human power are possible: http://www.recumbents.com/forums/topic.asp?TOPIC_ID=2070 The record is 26.96 sec @ 46.7 mph

Those videos make my case that about 90% of the population has no business driving. Drivers are nearly this bad in NYC, except the commercial truck drivers are better. Cars plowing into pedestrians on sidewalks are a pretty regular occurrence, sadly. No crashes, but typical asshat NYC driver...

He probably it just for the experience of saying he was out in such high temps. I did the same last year when Sandy was in full swing just to say I was out in the middle of a hurricane. I've never rode my bike during a blizzard but that's on my bucket list. Maybe this winter if a suitable storm...

Move to NYC. Fireworks are banned here. It doesn't mean you won't hear some this week, but it's certainly not constantly.

Doug, I suspect it's a combination of both the bike and your gearing. The fat tires and upright riding position of mountain bikes tend to make reaching high speeds problematic. And a lot of mountain bikes have something like a 44-12 gear as the maximum. That's only good for maybe 35 mph unless...

+1 I learned the hard way years ago that sometimes you just have to let some things slide. People will always make demands on your time. At some point you just need to say "sorry, I can't do it". Sleep deprivation sucks. I was on a schedule like Dave's through high school and much of college. 3...

I have that feature also on my Asus F2A85-V PRO. Most of the time the CPU fan is on minimum speed. The fan on my power supply doesn't even start turning until CPU usage is fairly heavy. When I put the two mechanical hard drives in standby, the system is inaudible, even in a quiet room.

If I had to climb grades like 25%+ I think I would have a Rohloff Speedhub. 526% total range with 14 evenly-spaced gears. If you made the top gear equivalent to 53-11, your low gear would be the same as 39-42. Have you considered a chainring with a triple crank? Those are usually used in...

I've been trying for a long time to lose about 30 extra pounds (I used to be 160). The extra weight hurts on climbs for sure. It also hurts everywhere else because it seems the rolling resistance of my airless tires isn't linearly proportional to weight. I wouldn't doubt my average speeds would...

Totally agree. In fact, for most people who have a system which is less than about 7 or 8 years old, and still working well, I might recommend they buy an SSD before even thinking about upgrading. Often just doing that will give an old machine new life. If it doesn't, they can always use the SSD...

You guys are making me jealous here with your maximum speeds! Most days I'm lucky to get much over 30 mph, although I'm not really pushing much on account of the potholes. I did hit 61 mph descending the Queensboro Bridge in the 1980s when I rode to Manhattan one night. There was a fierce...

I assume you mean improvements due to architecture changes? To me it seems that way. Haswell is only marginally faster than SB or IB for most things. You have AVX2 which doubles floating point performance but I'll guess nothing except benchmark software is taking advantage of that right now...

Yep-we still have a landline. It's part of our combined internet/phone/TV package. So far I haven't had compelling need for a cell phone. I just never do anything where I've needed to make a phone call from anywhere other than home.

I don't have one, either. In fact, I don't have a cell phone at all. I like gadgets, but not ones you have to pay x dollars per month to use. Now if someone came out with a very basic cell phone with no monthly fee I would think about it.

I can find plenty of buildings but the steps at Lexington Avenue are the only ones I've used regularly. Next time I visit a apairofpcs I'll time myself going up all 21 flights in his building.

The closest I can come to that is taking the stairs at the Lexington Avenue and 53rd Street station (escalator in pic but stairs are next to it). I think it's equivalent to at least 4 flights. I'm sure I've done it in under 30 seconds going up (and <10 going down).

Sure, it's hilarious, especially the part about fire trucks no longer being able to get into the subway, but it's also amazing some people are making such a big fuss about this. When you talk to rank-and-file members of the general public, probably 95% either like the idea, or have no real...

Sadly, this is not parody.

My setup (A10-5800K and F2A85V-PRO) supports up to 4096x2160@60Hz through DisplayPort. DVI is limited to 2560x1600@60Hz, and HDMI is limited to standard 1920x1080@60Hz

That's both good and bad. Good news-they're making something which is actually designed as a 4K monitor, not a 4K TV, and thus acknowledging the need for such a thing. Bad news-the price, obviously, and for me the fact that it's not 21" to 24". Now if someone makes a monitor using the 230 ppi...

I'm glad I don't have a job like this.

I had something similar happen last year when the drain pipe in the kitchen sink leaked, and water was coming out of the basement ceiling right under it. You already cut a few holes to air things out which is good enough. Let it dry throughly for about a week, then patch it up. There shouldn't...

On the question of which laptop to put it in, the older, slower one would probably benefit more but if you really want to go all out put an SSD in both. :) I'm totally sold on SSDs after having one in my new build. 15 seconds from POST to Windows 7 desktop!

Probably a few hundred for train fare. You're right, there's no way I'm flying. Airports are totally inconvenient for someone who doesn't have a car or driver's license. And the fumes at airports make me physically ill (i.e. I have a severe allergy to aromatic hydrocarbons). I just need to find...

I concur with Merc-get either a Samsung or an Intel SSD. As for capacity, 200 to 250 GB seems to be the sweet spot in terms of cost per GB. Cloning the SSD to match your installed hard drive should be relatively easy. When you remove the Hitachi from your machine, connect both it and your SSD to...

Not my cat but this is one of the cutest things I've seen.

20 years ago I would have been able to do a hard ride in hot weather and on little sleep. Now all bets are off. And I unfortunately gained some weight also the last few months due to not riding as much as normal. Hopefully I'll have the time and money to take a trip to the West coast one of...

That's pretty interesting. I wonder how far ahead the grid projects? It needs to be at least 50 or 75 feet ahead for ample warning at high speeds. In NYC, something like this would be invaluable. I can't say how many times I ran right into stuff which looked innocuous until I was nearly on top...

Things seem mostly back to normal for me now, but the last few days before were pretty awful.

Is it just me, or are other people experiencing very slow internet connections lately? A few sites are loading quickly, many are taking literally forever (i.e. like over a minute) to load a page. Is some kind of cyberattack going on?

I don't think compilers these days even attempt to optimize things. I've been programming microcontrollers for the last few years. One thing I've noticed is often when I write a routine in assembly it will run MUCH faster than doing the same thing in a higher level language and letting the...

Man, that's brutal. Congratulations just for finishing. Last year I think the most climbing I did in one ride was about 1100 feet and it hurt. I'm not sure I even could have finished the route you did, at least not without being about 30 pounds lighter.

I'm not sure any prediction that far in advance is going to be accurate. 5 years in this industry is an eternity. It could be we have some breakthrough or some new form of NV RAM and prices per GB of SSDs fall much more rapidly. IMO, we're at the point where SSDs are inexpensive enough for every...

Lucky you. When I had air tires flats were a weekly occurrence. And 99% of the time it was the rear that flatted. I used to stay within a few miles of home just so I could walk back should a flat occur.

Try these when they come out (I'm on the waiting list). They're supposed to negate any of the drawbacks currently associated with airless tires, although the truth is after using these for 9000 miles, the slight loss of speed, and slightly worse ride quality, are more than compensated for by...

You could selectively apply compression only to folders which don't contain already compressed formats. Even my Windows folder compresses by over 10%. That doesn't sound like much, but I'm gaining over 2 GB just from that. NTFS compression seems to be mild enough that CPU time isn't a concern...

Shock resistance alone is a good enough reason to install an SSD. The speed is just the icing on the cake.

The wall in this case is behind a bookcase. Besides that, the issue is that I can't use a monitor more than about 18" away on account of my eyesight, so no big screen monitors for me in the future. I'm not wearing glasses to use the computer. Can't afford $1500 now anyway, as great a price as...

Yes, I'm aware that TVs don't necessarily make good monitors. Then again, I wouldn't be using a 50" screen for a monitor, no matter the resolution. Like Chewy, I'm severely constrained for desk space. Besides that, anything much taller than what I have would block access to the book shelf which...
