The code snippet you showed may be "clean", but I have NO IDEA what it does, and I program daily in 5+ different languages. That tells me that Ruby is a poor choice, since the syntax doesn't resemble common languages like C, python, perl, fortran or bash.
The important question is: does it do analog input? That's the biggest limitation on the RPi IMHO. Adding a cheap AC current sensor for home automation monitoring would be a lot simpler if the RPi had analog inputs.
"Further research is needed to determine what exactly about the museum-going experience determines the strength of the outcomes"
Allow me to translate that into non-grant-proposal-writing-scientist-language:
"It was fun to study this, please give us more money so we can continue having fun."
I guess I should apologize for my misunderstanding of the rules. I think the combination of seeing people write "Posting AC to avoid undoing mods" and the fact that/. removes the "Warning! This will undo previous mods!" when you tick the "Post AC" box led me to believe that it's accepted behaviour.
True, an AC current probe isn't much use on an electric car. If you want a Hall effect sensor, the Allegro ACS758 costs $8 and can be connected straight to a multimeter. Just divide the voltage readout on the meter by the sensitivity of the ACS758 version you choose (X mV/A, x in [10,60] ) and you have amps (for DC, AC needs more effort obviously). Still more of a hack, but cheap.
You have a point in your statement: the Tesla is mainly a sports car, not built for being eco-friendly.
But, as the AC below has already pointed out, even a Ferrari/Lamborghini/Pagani doesn't waste energy just standing in your garage, in order to do something pointless. They do waste energy when running to have more powerrrr.
This is as if the Lamborghini had poorly engineered gullwing doors that required a hydraulic pump running 24/7.
To try and put this in perspective: adjusted for cost of living (OECD comparative price levels), the salary for a post doc position in Norway equals $48k a year in the US. For the UK, which also pays well for postdocs, it's $47k. Other European countries have lower postdoc salaries, e.g in Italy a post doc at IIT (which is a well funded national laboratory) pays the equivalent of $37k.
Ergo, at $50k, US postdocs are on par with the best paying countries in Europe.
So to sum up: the car is wasting 190 W continually, simply because Tesla needed it to appear futuristic. Once again, design trumps function:(
Given EU average CO2/kWh, this means it produces 1.2 kg CO2 per day just standing in your garage. For comparison, my daily commute in my 2001 Peugeot 307 1.6 produces roughly 3 kg CO2.
Sounds like a plan. "Sorry, you will be unable to deliver the kids to soccer practice tonight, the power company decided that your car will begin charging at 7 pm earliest."
Posting AC in a thread where you have modded is neither bypassing nor abusing the moderation system. The system is designed to allow this, and I personally think it's the best solution to the problem "Oh no, I modded those posts, but now I *really* want to reply to this one". Have you got a better solution?
F117s were used in Bosnia as well. One was shot down there. That conflict was decided by our air power.
It's "useless" to the GP because the GP has a worldview where all US weapon systems are useless, developed for the wrong reasons and used illegitimately in all cases to further our racial and economic imperialism, the military industrial complex, corporate hegemony and all the other crimes of 'murica.
Obviously.
+1 Funny.
Seriously though, the F117 is useless because it was supposed to be a fighter jet. It may be an alright strategic bomber in scenarios where the enemy has much lower capabilities than you do (Iraq, Panama, Bosnia), but so is a B1-B or a B52 for that sake. And as you say, the Serbs managed to shoot down an F117 with the SA-3 and low frequency radar, so "knowing SA-5 missiles cannot hit them" seems a bit overconfident. The reason they were so effective in Iraq is that the Gulf war was won psychologically. I mean, you had T-72 crews surrendering to Apache helicopters. The Hellfire wasn't that good...
Well, what would you say high yield is? I can't bring myself to call a US cyber weapon "high yield" unless it destroys or disables infrastructure on a large cale. Bonus points for egg on faces in Riyadh.
The reason it has gotten so much attention is the same reason the F117 got a huge amount of press even though it's practically useless.
The combined computing power of the guidance computers on the space shuttle (IBM AP-101) is less than the computing power of a new "smartwatch". Where are my glasses that project information from the internet? Oh wait...
I looked at the 33s and the 35s. It looks like the 33s is likely to have this arrow-key problem, but the 35s will not have it, since the arrow keys are physically separated.
My protip: check how the arrow keys function. A few years ago, the approved calculator here was the hated HP 30s. It had arrow keys where pushing "left" would instead push "up" 5% of the time. And then you could not push "down" to go back to the expression you were editing. I witnessed several people physically destroying their 30s due to this frustration.
Indeed. I'm using a Pi for my Wifi-controlled engine block heater unit. The PC would've been a lot harder to weather-proof, and it would probably have been stolen in 2 weeks. The Pi sits smugly inside an anonymous grey box on the wall, looking like a junction box to random passersby.
I actually clicked the last link to try and RTFA. Damn, that is the worst piece of writing I've seen in a while. No wonder the summary is crap as well./. why do you link to these shitty articles? I was expecting to get the EFF site, not some random "tech journalist" who couldn't pass 5th grade English!
My HTPC has a passively cooled Geforce 210. Works like a charm, quiet enough that the wife hasn't thrown it out of the living room. Sure, it's slower than the Intel HD 4000, but it cost me $30 when the old GPU died.

Informative and funny! Not bad for an AC, not bad at all.

If you don't log out when posting ac, they still delete your mods.
I didn't know that. In that case I tend to agree it's bypassing the moderation system.

Huh. Modding "myself as an AC" up never crossed my mind. Guess I assume most people are honest.

Mod this up.
With a slightly more expensive meter (200-300$) you can do clamp on current measurement AND keep all of your body hair!
Why so expensive? A clamp on probe costs $40 on ebay, will work with any cheap multimeter.
If you want to go even cheaper, all you need is a self-wound coil (50-100 turns will do) around an iron C-clamp, three resistors and a capacitor.

Do you like the 35s? I'm considering getting one as a backup for my Casio CFX-9850 (which doesn't have RPN sadly)

Yep. Spent a significant number of hours in a garage underneath a 240 in fact. Great car when you're 18 though, especially the turbocharged ones.
