> Getting a cell down the block from your house would seem to be nearly as hard as running a line to your door

A 5G cell will be 0.1-1.0 km in radius and cover dozens to hundreds of users. In a suburban area, that might be an entire large subdivision. The cost of getting fiber to the cell might be just as much as getting it to a fiber distribution hub in the subdivision, but with 5G once you do that you're done. With FTTH, you have to then run it to each house, which will take (in the aggregate) way longer than it took to run fiber to the subdivision. The branch factor kills you--yeah, it's just a couple of hundred feet to each house, but it's a very labor-intensive couple of hundred feet (under yards, into basements) that you have to do for each subscriber.

Also, all bandwidth is shared--it's just a question of where the sharing starts. GPON--what's typically used for FTTH--involves sharing 2.4 gigabit down/1.2 gigabit up between 16-32 users per PON. That comfortably supports gigabit service with reasonable oversubscription. A 5G small cell will have less bandwidth shared between more users, but will be in the same ballpark.
In your country maybe. It is very much a cultural thing. In the Netherlands to get your driving license, you learn to stick shift by default. If you don't want or cannot learn to stick shift, you can get your license but you get a notice in your driving license that you are only allowed to drive automatic transmission. Learning to drive automatic is still very much an exception here.

Most consumer cars in the Netherlands are still sold as manual transmission, probably because the price was usually lower compared to automatic transmission. But we won't have a choice forever, since we are heading to an hybrid/full-electric future and almost all electric cars have a CVT anyway.
The only video I could find of the process: https://www.youtube.com/watch?v=bVAPUxSH_6Q

I'd like to see someone interact with it - is it possible to get "wet" from dry water? Can you get the water back out?
You should give WSL a try now - a couple of years ago would have been shortly after it was first released, when it was VERY early, and only barely able to run some of the more sophisticated tools you'd want/need.

WSL has come a LOOONG way since then, and yes, we are still working to improve disk IO perf.
I went to the junkyard got a manual and pedal and put it in my car.
Note, paddle shifts alone are not a good signifier, depending what's underneath them. There's a HUGE difference I find between:

a) Automatic with paddle shifts: still has a torque converter between engine and wheels, soft response on pedal, and double-guesses everything you do

b) Sequential and/or dual-clutch with paddle shifts: still has a clutch, direct connectivity from engine to wheels, same response to gas pedal and more control

First one is zero fun to drive (for me).
Second can replace my manual easily.

Not that it’s that prevalent but lack of demand serves as a kind of price constraint https://www.insidehighered.com/news/2017/11/13/spate-recent-...
I made the switch to automatic a year ago, mainly so my wife could use my car--and I still suffer from Phantom Clutch Syndrome. I am tempted to switch back by the time my kids are old enough to drive so I can teach them, that is if humans are still driving cars then.
In short. No. Two big issues with current state of the art solid-state batteries are i) the amount of current that the batteries can handle is typically low at least because the conductivity of the solid-state elecrolyte is much less than a typical liquid electrolyte; and ii) cycle life is low at least because small defects in the electrolyte/electrode (cathode and/or anode) interface(s) are not self-healing. In a liquid electrolyte, the liquid can accommodate more changes at the interface because it is liquid.
Switching to a manual finally killed my habit of "quickly replying" to a text or e-mail. Sad it took that, but I'll accept my longer lifespan now.

Are there plans to rewrite/port Spidermonkey to rust as part of the Servo project?
It can be at least partially explained by a mismatch between the "cloud" model and the underlying engineering (and market) reality [1].

One has to build (or buy) for peak bandwidth. Selling it pay-as-you-go, with no regard to local maxima, means one has to price that rate high enough to account for the typical (and then some) spikiness in traffic. [2]

It's not hard to imagine that something like a UGC video site might significantly increase that spikiness ratio, if only because of the sheer quantity of data involved. Moreover, it's a large quantity of data transfer per user, so even modest user growth would result in huge network use growth. As a sibling comment pointed out a cloud provider "may not really want that type of client".

Perhaps cloud providers could start charging on a more traditional-ISP 95th-percentile style basis for larger customer and engineer their networks accordingly, but then they might have to keep those customers corralled in specific datacenters, which would remove part of the value of cloud infrastructure.

[1] Forgetting that "the cloud is just somebody else's servers" also led to the delusion that one doesn't have to "worry" about hardware failures in the cloud. Fortunately, it's now common knowledge that EC2 instances are subject to disappearing due to hardware reasons and that this needs to be "worried" about (engineered around).

[2] There is a similar issue with residential electricity pricing, where consumers pay a flat rate but the utility actually pays time-of-use (potentially a much higher rate on the spot market). Somewhat related to but not identical to rooftop solar using the grid as a "free battery", since that's also time-of-use. These come up routinely on HN discussions of electric power.
I still have a manual transmission car, and am in the process of teaching my sons how to drive it.

Granted they are not popular, but I prefer them. Sadly the market does not. And electric cars, which seem to be the next iteration of the automobile, don't have transmissions at all, so the ability to drive a manual is really looking like it will soon be a fairly useless skill.
I would assume this is not as simple as it looks.

A lot of the data is simply noise; of the part that might be useful, a lot would contain proprietary information that companies would be reluctant to part with.
A huge part of the data is generated but never captured digitally
Yes, but automatics with "paddle shifts" have very soft transition and very soft/delayed gas pedal reaction; whereas dual-clutch/sequential with "paddle shifts" have very fast transition and very straight gas pedal reaction.

The true automatics, or CVT, there's limited need (or fun:) in paddle shifts outside of hills, poor traction, etc.

For sequential/dual-clutch, paddle shift operation is direct... and fun :)
Yes, that's the root cause of many of their fulfillment issues. And it makes sense for something like a mass-market book. It makes less sense for other things.
>Hedge Funds Trounced Markets Over the Long Term

Looks very iffy to me. Googling survivorship bias "The flagship investable HFRX Global Hedge Fund Index, for example, has undershot the non-investable HFRI Fund Weighted Composite Index every year since 2003, by an average of 560 basis points." https://www.ft.com/content/16e4fb60-46ad-11e0-967a-00144feab...

knocking that off the 10x 20 year return shown for the HFRI would reduce that to a 3.6x return

How it works is a fund company launches the super fund and the wow fund. Then the super fund goes up 20%, the wow down 20%, then as a holder of the wow fund you get a letter "the wow has been discontinued and merged with the super fund" Then the company claims all its funds are up 20%. An awful lot of them pull that kind of thing and you have to correct for it to get useful stats.
I always had an easier time getting up snowy/ice hills (in Boston) than my friends did in their autos. I remember once driving up a hill in front of a friend so he could use my tire indentations to get up behind me.
Yep, when over the years your same 45min commute turns into an hour and a half commute, automatic is so much better. That and then getting work closer to home.

I believe too many made out fairly well and by not wiping out the shareholders we've created a gaping maw of a moral hazard. Corporate governance is in tatters, has been since roughly the 80s when the goal became quarterly earnings at all costs.

Wiping out the shareholders when bailing out would have incentivized the next set of shareholders to police their investment. Now the only disincentives are executive compensation and some additional express limits on dividends.
I learned to drive stick at 34 just for fun. Now own a Mazda 3 and MX-5. Worth it.

It's not about out performing an automatic transmission it's about engagement. For some people that's not going to have any value. For others there is no going back to numb econoboxes with automatic transmissions.

It's a shame more people don't get over the hump and get to see what driving can be vs. what it is for most.
"It can be used as a medium for volatile compounds, as materials stored within the dry water can be reduced to powder and stabilized – reducing not only the volatility of the substance, but also its weight for transport."

Anybody know how it's possible that adding an additional substance to a chemical compound could decrease it's weight? Or does it just mean that less volatility means it can be transported in lighter containers?
Sure, but fixed wing drones are even easier to build, fly and (modulo the landing bits) land than quads. Even independent small shops are designing and shipping recreational performance fixed wing drones reusing drone parts (BlackSheep's Caipirinha 2 comes to mind: https://team-blacksheep.com/products/prod:tbs_caipi2_kit).

Quads just have the ability to hover, which is desirable in a lot of industrial applications. They're also a nice example here because they have the most expensive avionics software and hardware (clock speeds have hard minimums) and THEY are cheap.
How are you going to trade with other countries? Are oil exporters going to accept your tropical-coin in exchange for gasoline? I doubt...
Despite the title, it never explores why this phenomenon is specific to America, except to note that "the 5-speed manual is [still] the most popular transmission in the world".
I agree with the luxury portion. My university hasn't added a "cheap" dorm in decades. Now they're all suites, where 2 or 4 people share a bathroom, and are much more expensive.

I think a big part is students growing up in a middle class lifestyle and wanting to change as little as possible. I lived in the cheapest dorm available (no AC in the heat and humidity of Iowa). At current rates, 4694/year versus 6415 in the super nice ones, all before the meal plan.

So we have tons of people with low earning potential trying to maintain the lifestyle their parents have provided for them despite the fact that maintaining that lifestyle after college will mean they're saving little to nothing, and that their student loans will live on for many years.

People waking up to the harsh reality of what starting wages will get them, how long student loans would take to pay back, etc. would go a long way toward cutting the fluff costs associated with college.
You're talking to a student who's spent 15 years attending community college and then University while working several full-time jobs to get to where I am today.

Don't tell me I'm out of touch when I'm living exactly what I'm preaching. Don't tell me it's impossible when I'm doing exactly what I advocate for.

It's time to change the University system... and standing here and saying these things are too hard to fix is why it's so broken.

The solution isn't more tax-payer subsidies... it's fixing what we expect out of Universities, and what we expect out of students.
> habit of "quickly replying" to a text or e-mail.

Once you are on the highway and driving at 80 km/h or above, in most manual cars you are already shifted to the highest gear. In my Hyundai Matrix I am already shifted to the highest gear at 55 km/h.

Oh, and regardless which car you have, please, do not touch your mobile phone.

Actually I take back the mortgage part. People these days are lucky if they can afford any kind of house, big or small, at least in or near big cities. Most people are probably just glad to own anything let alone a big house.
I like manuals because they feel better to me. This is totally anecdotal but to me it seems like the stick keeps me more engaged with what's happening with the car so I find I tend to be less distracted. It also occupies a hand so it definitely prevents a lot of phone usage. If this could actually be proved I'd definitely welcome a return to manual transmissions as sometimes I feel like the only person not on their phone in traffic...
It doesn't say how to get the water back from the powder.
We do this as well for our "DevOps-as-a-Service" consulting. We have a phase I discovery session before the build session where we map out different potential solutions and the cost / benefit of each one.
In the UK most cars are still manual. Less so for the more expensive you go but I'd guess more than 90%.

I have driven automatics a handful of times. The longest I spent was 2 weeks in a motor home touring the Rockies.

While I can see the appeal for around town driving driving up and down grades was a bit of a pain. Basically I had to learn the behaviour of the transmission and use a combination of the exact amount of throttle, hold down gears and flicking between tow haul and normal to get the gear I wanted. It was more hassle than having to change gear manually.
It is true. We had endless conversations about Ambien in Hackersnews, one example here 50 days ago: https://news.ycombinator.com/item?id=17591515

I was prescribed Ambien by going to a doctor for insomnia. No tests, no nothing. Sure I legit had insomnia, a pretty bad one at that, but they just asked me my problem I told them I can't sleep, next thing I know I'm prescribed Ambien. This the university hospital one of the best universities in US, not some random rural hospital.

You should never ever use any drug without doing your own research about it. Doesn't matter if #1 MD in the Western World prescribed it. Drug industry is nothing but a game to make 1% of 1% richer.
Your comment implies that innovation was impeded in other industries because cosmetics "snatched up" the patents. I'm not so sure. Typically, academic and institutional researches DNGA* about patents. As a nascent technology shows commercialization potential, there is incentive for the patent holders to find some way of monetizing. I would imagine (but admittedly do not know) that a cosmetics patent holder would have little reason to refuse to license to some entity operating in a very different field.
I never understood why Dick Fuld wasn't put in jail. He deliberately misled investors on the amount of leverage they were operating under. I thought Sarbox, which required the CEO and CFO to sign off on their public financial statements, would have caught this.

> Take the Subaru BRZ. The popular sports car was once sold only with a manual transmission, but sales are now 90 percent automatic, Fiske estimated.

I find this a bit difficult to believe.

The automatic option has a reputation for being pretty good, but the manual is excellent. It was certainly never even a matter of choice for me, and for the growing number of (BRZ/(GT)86/FR-S) enthusiasts I know.

Yes, I'm in a niche, but so is the car.

But the prices aren't just affecting the floor models. DJI's had to move into the $300 range (I literally just bought one) because of steep competition in small shops making custom drones and other vendors pushing the cost down as various manufacturing houses spin up.

My other half has a chronic psychiatric condition, after struggling for 2 years we'd found a combo that worked. Prior to that though, we'd had to check drug/drug interactions ourselves because a previous doctor simply didn't, nor did the pharmacist...

Been using Epocrates (the free parts) to check interactions and side effects. Beats digging through the FDA website for it.

One suggestion, NEVER look up common drugs like Advil.
You're correct. Sorry for being unclear. Also I genuinely don't know if you're even allowed to do video over HAM. I've heard stories about how local ham activists love to report folks for mucking up their precious bandwidth.
Not many Teslas, but lots of electric hybrids. A hybrid Toyota Camry traveling the same distance as a regular one will cause the same amount of wear and tear on a road, but will pay less gas tax.

For this reason US states have started experimenting with taxing VMT. You don't actually need to track mileage; just measure the odometer at the end of the month.

As far as tracking concerns, Manhattan is an island connected via bridges and tunnels; all you need to do traffic pricing is to toll the crossings.

> I still suffer from Phantom Clutch Syndrome

Based on personal experience, it takes about three years to get over that. YMMV.
This is kinda sad, and hope it doesn't happen in Canada. I understand that some people prefer automatics because they are easier to drive, but I personally find manuals more fun. I also feel in more control, especially in winter weather. Being able to use the engine to slow down (downshifting) is very useful in icy conditions, when ABS gets retarded. Also my personal opinion, but being able to drive a manual feels more manly ))

That's true, but most of my driving isn't highway. I think if it was, I'd be less interested in a manual as it wouldn't change much.
I grew up in India and loved driving stick shift. Once I moved to US, I transitioned to Automatic.

Biggest reason I miss Stick shift is that, it just felt that I had a stronger connection with the car and the acceleration was more predictable. With automatic you might not be in the right gear and the car might upshift too soon or too late.

A potential side effect of the stronger connection is that more involvement leads to more spirited driving and potentially traffic tickets.

Then I got a Tesla. Beauty of Tesla is that it has just has one gear, so you are always in the right gear. So this avoids the biggest issue with Automatic. OTOH, because I am not manually changing gear, this avoids the spirited driving issue. It is now an appliance and just works.

Amazon has to bake the cost of shipping and handling into their price structure. It isn't free for them and they can't take a loss on their core business operations forever.

A mass market merchant who bulk ships to their stores has certain advantages over that model. One who stongarms their suppliers to sell them product with minimal to negative margin can beat Amazon.

Walmart can only stock so many SKUs. You can't walk into a brick and mortar store and select from 1M+ products including niche items that aren't profitable to sell at retail.
Sometimes people are just worried for others...like: "You have a nice store, it would be a shame if it burned down" :)
There was before the government got its hands in it.

Before guaranteed loans students had to be verified based off their merritt to get a loan. Lenders took a real risk and had incentives in the person being successful so they would have hopes of the loan being paid back. This was near perfect as schools could not not charge more than lenders would risk.

Thes solution in this case is to remove the government guarantee, and let the free market work.
There is an enormous gap between being able to tolerate working on something vs 'really' wanting to work on something.

Ya, I have no idea how someone parallel parks a manual (w/out hill assist) on a 15% grade; I personally have to keep one foot on the break and one foot on the accelerator!
I feel the same way.

City traffic commutes and long highway cruises seem to be what most people think of when they think about driving, but it can be so much more than that.

Few things are as fun as a balanced car on twisty mountain roads, and in that recipe the manual transmission is a key ingredient.
I've got a JL rubi.

Low speed/rock crawling/grades I feel would suck with a clutch, though. On fairly basic rough stuff like cutting through woods over logs and what not to get to my camping destination I often need 2 hands on the wheel to gently fight mud/etc pulling them in the wrong direction. The easier control of your torque w/ manual is probably nice, though. When you're doing this stuff you're typically locked to under 15mph because of the sway bar disconnect (it pops back on if you hit 17mph) & lockers, so you're not even changing gears out of 1st so maybe it's not even a problem.

Anyway hope you're able to get some adventuring in it, I moved to the big city and haven't put many miles on mine since I bought it in May. Just a few offroad trips. Hopefully a caravan to Overland expo next year.
