I think the fact that you have a train station right outside your door might color your attitude on how useful the train system is. Not everyone is so lucky. In many countries, they price real estate on how near it is to the train station and living as close as you do is a real high dollar accommodation.
Yup. I've lived near a station in two places and far from a station in one other house.
Living near a station certainly increases the utility because you don't need a car to get to it. However it is still worthwhile driving to a nearby station and getting on the train to the airport - which is on the other side of town. Parking at the station is free compared to $50 a day at the airport. The proximity to the train station was a factor in purchasing the house we currently live in.
> Yep $400 million for a light rail on a bridge that has no other light rail on either side to connect to.
People complained about the lone blue line on the Portland MAX light rail. Then they continued adding and several years later it's excellent and goes plenty of places. It takes me from a short walk from my front door to the airport on the other side of town. You have to start somewhere. Getting the difficult bridge bit out of the way first is not a bad plan.
But are they engineered to handle all CPUs running, balls out, full time? Most desktop heat sinks, aren't. Most games still being largely single threaded and GPU bound.
I've not had a problem and I've left my CPU running balls out, all cores, all threads, for weeks on end.
>Connecting and disconnecting creates wear. When you have a docking station, or even a USB plug or a ethernet jack, they can take wear and tear and become loose and sloppy after a certain number of connects and disconnects. Not to big a deal as you need a small metal to metal connection to allow electricity to flow. If drop from 100% of origional contact surface are to 50% or even smaller of the designed surface area in contact, it still works.
Reliable, leak proof, detachable water couplings exist. They tend to have a tube diameter thicker than a laptop though.
Do we really think the cable companies care, so long as we're still paying them for the internet access? They have a monopoly no mater how you look at it.
They certainly give the impression they do with their internet+TV+phone bundling.
>Let's see, I can buy item A which will run for 3-5 years with no other expense, or item B, which costs roughly 90% of A, which is user fixable but with a maximum average lifespan of 3 years and will require additional expenditures on battery replacements, etc
Nonsense, I love shiny new tech and I replace this stuff every couple of years in order to access shinier, newer tech. For something I use multiple times a day, the costs are small compared to food, housing, clothing and transport.
>there are a few high power commercial applications
For whatever hardware I have today, there is a class of algorithm I can run, limited by the runtime. As computers get faster, I've been able to do more and better data crunching, but always limited by the CPU and memory.
At work I use a server farm. This is fine.
However travelling, free from interruption and co-workers in the same time zone, is prime programming and testing time. Turnaround time matters. So while I'd love a lightweight laptop for its lightweightness, I always veer to the fastest thing with the most memory and cooling that's going to mitigate throttling when I'm running markov entropy estimate tests at 30,000 feet in the air.
>The 'proper' heat sink is the one in your server.
Server heatsinks are nasty. Small, with a tiny and very fast fan pushing air through it and making a horrific whining noise (like some/. posters). This is fine because they get the job done and they live in a server rack (unlike some/. posters).
Today's closed loop CPU water coolers and big low speed air cooled coolers are pretty well engineered things.
It's a 2015, top of the line model with great performance. So needs to be compared with a 2015 top of the line used corolla. Cheaper? Yes.:https://www.kbb.com/cars-for-sale/486893614/?totalresults=109&index=2&vehicleid=403139&year=2015&distance=150&atcmake=toyota&atcmodel=corolla&searchtype=used&intent=buy-used&persistdata=true&includelistings=true&maxlistings=5&pricetype=retail&_=1531781530626
>Do you think it possible that this could be because of the car being subsidized on its first sale,
The price of used Nissan leafs went through the floor when the very different 2018 model came out. Also it's a fairly ugly car, but very nice to drive and loaded up with nice tech, so it's function over form. I think used Leafs are a bit of a bargain. It was subsidized for me because it's used. The government subsidizes the sale of new electric vehicles.
The car was an ex lease vehicle. That's why it was available while only being a 2015 model.
The car has been a good deal for me because I don't drive many miles a day and its range is sufficient to get me across town and back again. Being a pure EV, the maintenance costs are low and the fuel costs are low compared to ICE vehicles. Also the 0-45 performance is superb. It's not great at higher speeds. So it's a good in-town car.
Having got used to driving an EV, I won't be going back to an ICE car. The options for EVs should improve in the future. My other car (a Mazda 5 minivan) feels very laggy and unresponsive compared to the Leaf.
Curious how you paid "your fair share" for infrastructure like roads and bridges - all those more expensive to run ICE vehicles paid for them with gasoline taxes.
EVs will remain cheaper than ICE vehicles as long as they get to use the roads, bridges and tunnels for free.
I pay my car taxes to the state. I pay my income taxes to the state. My car is light, so it does very little damage to roads compared to heavy vehicles. So I do pay my fair share.
Eventually, EVs will be similarly priced to ICE cars and ICE will quickly evaporate. The problem we currently face is mass manufacturing batteries in a way that will lower their cost.
My used 2015 Nissan leaf was significantly cheaper to buy than an equivalent ICE car and is significantly cheaper to run.
Well there's ChaDeMo, J1772, CCS, CCS with the extra testicles and Tesla.
From an engineering standpoint, ChaDeMo wins. One connector, 'DC fast charging' - which actually means the charger is outside the car and so can be much more capable, canbus for negotiating the charge, high voltage support allowing thinner, more flexible cables and a clever name. But it's Japanese, comes on Japanese cars (my Leaf has it) and chargers are few and far between. I only ever used one (at my local airport). Being the best solution, it is obviously never going to become universal, because people love things to be crappy and awkward.
J1772 seems to be the universally available one in the US however it's an AC pass through, so the car has to lug around the weight and volume of the AC->DC and battery charger circuit within the car.
CCS is like J1772, but has two connectors, one with the DC testicles and one without (see the picture in the wiki , which is entirely stupid. Go to a fast CCS charger with a car that doesn't take the testicles and you can't charge. Your car has to have the charger to accommodate the non-fast charging variant.
Tesla is it's own thing. Only works in Teslas. This is stupid. It's easy to see why Tesla did that, but it incomprehensible to me that the governments didn't get together and standardize internationally the charging mechanism, just like they did for the mechanism petrol refueling.
The upshot of this failure to standardize is that a large fraction of the EVs out there drive around wasting energy lugging high power charger circuitry and a bag full of adapters in the truck or frunk that need not be there.

Based on the previous time you ran them...
And RdTSC time stamping of inner loops.
Because the processes take as long as expected.

Entropy is never good at 30,000 ft. You will eventually divide by zero.
Entropy always rises. So if you can't find it at 30,000 ft, just go to 30,001 ft.

A little bit. Yes

Docking stations need to come with a water loop coupling.
Plug in the laptop and cold water is fed through pipes in laptop's body.
There is plenty of space for the coupling points now that all the useful interfaces have been removed from laptops.
Thanks
Cheaper than say a $6000 civic/corolla?

>You don't need DC fast charging at home.
DC charging doesn't need to be fast.
Yep. I found the APIs and driver support to be convoluted and messy.
The last HSM I purchased cost $16,000 dollars (for a single PCI card with card reader).
In what org does the person with the knowledge of the software signing process have the autonomy to sign off $16,000?
Of course, to do it right you need three. So $48,000.
HSMs need not be expensive, but they are, partly because of the FIPS certification process and partly because people can get away with it.
Who said the charger port comms needs to be connected to the rest of the car?
I don't doubt that car makers would do that. But they shouldn't.
There are multiple technical standards. But in Europe, the government mandated Type 2.
https://www.autoblog.com/2013/...
And so creating a third zone of differentness, instead of the USA, Japan, China and Europe all getting together at ISO and picking a single one.
If only there was a continent wide standard...
