JFYT, that is a technique widely used, but normally not on tunnels that are (final diameter) TBM excavated, only or those that are excavaed through more traditional means (explosives/excavators).
Basically if you want to excavate a tunnel (say) 12 m in diameter, you first bore a tunnel with a much more small TBM, typically 3.6 m in diameter.

This pre-bore provides three great advantages:

1) Ventilation of the tunnel during the enlargement is greatly simplified

2) You have a very sensible saving on explosives (if explosives are used) or however faster excavating times (because a large part of the amount of explosive is needed to "start" the demolition of the rock, i.e. pull the center "core" out)

3) From the pre-bore you can (when you encounter problematic terrain) drill radial holes for consolidation of the surrounding terrain (though cement injection or other similar techniques)

If the final diameter is TBM excavated as well, #1 advantage above is only partial, #2 is almost non-existing while of course #3 remains, BUT, you cannot make the pre-bore much smaller than the 3/3.6 m diameter as otherwise it would be only useful as a geo prospection mean, as it wouldn't be practical to use it for anything else, and there would surely be issues (for smaller diameters) with ventilation.

AND the other bad news are that - more or less and as a first approximation - a TBM has an operative tunnelling speed of roughly 400 m/month that is almost independent from the diameter (while a traditionally excavated tunnel is more around 100 m/month without pre-bore and 120/130 m/month with the pre-bore), so while it may make sense (of course a lot of factors are involved), if you have a 4 Km tunnel to make a pre-bore that will add roughly 12 month to your 50-60 months project excavation time (traditional), it won't make much sense unless for other very particular considerations to add those same 12 months to the 12 months a full face TBM would take.

What is often done on full face excavated tunnels with TBM is prospection holes (horizontal, drilled from the face of the TBM) in the 30-50 m range, to explore what lies ahead in the immediate future.
Tell me what you mean by "the nature of data" and I'll tell you if I agree with your definition. I don't see why the dimensionality of a dataset is not its "nature" for example.

True or false?

Microsoft is a company that actively tries to prevent any comparisons of its products with other products, sometimes through threats of filing legal proceedings.

True or false?

Only government agencies are capabale of discovering flaws in Microsoft Windows.

True or false?

A closed source kernel is more secure than an open source kernel.

(For the avoidance of doubt, here "open source" means open to public inspection free of charges, terms or conditions, such as various UNIX-like kernels. It also means the right to make changes, re-compile and re-distribute without charges.)

True or false?

This determination can be made without comparing the source code for both kernels.

Hypothetical and questions:

Product A has 5000-6000 new vulnerabilities per year, about 15 per day.

Product B has 5-20 new vulnerabilities per year.

Can we explain this difference by focusing on the parties who find the problems that require patching?

Alternatively, should we focus instead on the products?

What if Product A is more complex is than Product B?

Does this make any difference?

What if Product B can perform many of the same functions as Product A, particularly the functions that are most often used to exploit a vulnerability.

For example handling data to be sent or recieved from the an untrustowrthy network such as the internet. In other words, networking with remote computers ("internet") as opposed to only networking with local computers ("IBM-compatible PC LAN").

Unlike BSD UNIX, Windows was originally designed for only local networking, where very little if any security is required.

True or false?

Windows still retains some of this original design and source code.

That is a trick question because the Windows source code is not open source. How would anyone verify what is still in that source code?

Keeping the source code from the eyes of its users does not protect them.

It may be possible to reverse engineer Microsoft products or patches to learn how Windows works.

"Good guys" may do this as well as "bad guys".

A vulnerability could be discovered by someone who is not even old enough to work for a government.

Repeat question:

Should we focus on who finds flaws in Windows or should we focus on the Windows product itself?
Clearly we have some work to do here!
I have to assume that the same set of people complaining about high rent prices because of NIMBYism are not the same people dismissing this solution, which has the subtext of being NIMBY-proof. But they're probably the same.

This thread is hilarious.

ML is powering most or even all self driving car efforts underway, powers online translation services, numerous vision projects and speech recognition besides winning competitions meeting or exceeding human performance on the same data.

I'm just as allergic to those that hype some technology as I am to those that will snarkily discard something with arguments that have already been laid to rest, in some cases multiple years ago.

Xkcd is fun, but isn't necessarily prescient nor does it have to be accurate, when this cartoon was published the writing was already on the wall and that's 3 years ago. It's fine to be skeptical about new technology but before you start criticizing it make sure that you have at least a rough idea of where things stand lest you end up looking foolish.

Sure, ML is abused and if we're not careful we will see another AI winter because of silly hype and ascribing near magical properties to ML. But at the same time snark, condescension and a-priori dismissal of what is most likely the biggest landslide in computing since the smartphone is - especially on a site that deals with both hacking and novelty - something that I would not expect.

Compared to the HN love for the next JS framework or language fad this attitude is surprising to say the least.
This is pure conjecture, as I don't have the links on hand and quick searches don't turn them up, but I saw a study also on HN at one point theorizing that there are pathways for CO2 sequestration as fats/fatty acids in many animal species. (In the terms of the paper that I think I recall, an hypothesis was the increasing levels of atmospheric CO2 due to climate change/industrial outgassing/car exhaust were potentially implicated in the cross-species overweight/obesity epidemic of most species living in human cities.)

I wonder if a follow up study into this surprising ghrelin reaction that increased CO2 pressure in the stomach induces it rather than suppresses it may implicate just that sort of carbon sequestration process?

Three years back, I used to sweat about not knowing Angular and Rails. They were the rage back then. I still don't know them, and I can see how React has become a thing now. It's hard to put in words how misplaced fear of "ML-taking-our-jobs" is when you take few moments to look beneath the iceberg and see how awful is the software that world depends upon.
Tesla pioneered mass-produced liquid-cooled electric motors. Those were rare before Tesla. Now they're much more widely used.

Tesla was forced into that technology. The original Roadster had a two-speed transmission and an air-cooled motor. The huge jolt on the transmission when it shifted during acceleration wore it out in months. So Tesla had to develop a motor with a wider power range that would fit in the original space. That forced them to liquid cooling. Previously, liquid cooling an electric motor was considered unnecessary complexity; just make it a little bigger and use air cooling. Now, it's common for electric cars and is being used for electric powered aircraft.
My gut feeling is that the average life expectancy is determined less by what percentage of population has access to top quality medical services and how good that top quality is, but instead mostly by how many people have to postpone or limit basic medical services.
There aren't really any eggshells to walk on unless you're inventing them (and the person you replied to was not impolite about the correction). Chelsea Manning identifies as a woman. This isn't something that happens overnight; it's impossible for you or I or the great-grandparent to know when Manning decided to come out to family, friends, that sort of thing. As such, it's incumbent upon us to use the most currently, and thus least likely to inadvertently offend, pronoun and referents. (This is also why it is poor form to use a trans person's pre-transition name when referring to them in the past tense. In my experience, if a trans person would rather be described using that prior name or prior pronouns for his or her prior self, he or she will let you know.)

They were very different cases:

1. Manning thought she was doing the right thing and didn't realize what she would cause. Snowden knew exactly what he was doing.

2. Manning leaked the docs to something that is probably a Russian front but something she didn't realize was a Russian front. Snowden, if he didn't turn over the leaks to the Russian and Chinese governments, certainly put them in great risk of being turned over.
Think of it as if you were raising a zombie, all deep in the uncanny valley. This is how some people feel when facing a psychopath.

They don't quite act within human parameters.

To overcome this you have to be quite callous yourself. It is a reaction and emotion.
The determination on which animals in Canada to rescue, and which can be returned to the wild is done by the Department of Fisheries, so there is neutral oversight provided by a government entity. Those claims are easy to prove.
Automating Your Predictions Using BigML and Zapier
I see what you're saying, but that looks like a function call embedded in the HTML.

Embedding your programming into HTML doesn't make it any less programming. Otherwise, you could say web programming doesn't exist since it's all just HTML script tags.
On top of this I found atom to be pretty unstable, especially when using a bunch of plugins.

Text editors are a primary tool and instability is unacceptable. I can't remember any time vim crashed on me.
"The Paquete is an alternative to the web in [Cuba] where, according to some estimates, fewer than 5% of homes are connected.

It consists of a terabyte of data bringing together the latest music, Hollywood movies, TV series, mobile phone apps, magazines and even a classifieds section similar to Gumtree or Craigslist.

Every week, unidentified curators compile a selection of content and deliver it via a complex network of hundreds of distributors who, much like old-fashioned newspaper delivery boys, bring the Paquete to the door of its subscribers."

> Give it a try. Surprisingly it seems faster than than the .net version - perhaps because WPF and WinForms apps never feel fast. I'm impressed.

Unfortunately I can't give it a relistic try, I can't find a Linux build and I wouldn't get a realistic feel for performance inside a VM. My prior experience with the performance Electron based applications comes from using software such as Atom, VS Code etc. I can't say I've experienced WPF apps being that slow when I do use unvirtualised Windows, though (I think I noticed startup time, but that's about it).

> Feature wise it still seems kind of anemic - you couldn't use it exclusively. Hopefully they will be able to improve on that now that they have twice the manpower to work on one platform.

Yeah, everything I read pointed at it being a reasonably early release - which is fair enough. I'm sure they'll iterate and improve.

This won't happen until EVs roughly hit price parity with ICE. Most people aren't willing to pay more for an EV. Many people would pay a premium for ICE (for ease of refueling).

But once EVs are cheaper the change will happen quickly. But quickly in terms cars still isn't fast. Even if another ICE was never built or imported to the USA, it would probably take about 8 years for EVs to the majority. We keep old cars around for a long while.

Also, a lot of people assume self driving and electric go hand in hand. But really, there is no reason they need to. In fact, if you really do have a fleet of cars, that might make EVs less attractive due to charge time. Though you can make it work anyway.

Sounds like you're pretty emotionally invested in this argument, so this may be flame-bait, though it's not intended to be.

You were 16 when the laws were enacted. Of course you'd mock them. It even clearly shaped you as an adult: you're still angry about what you see as nanny-statism.

Still, it's just your natural growth as a person. As a child you're protected from crassness, then in your adolescence you revel in it, then you have children and shun it, then once your kids are too old for you to control what they see you throw your hands up at it and declare the world lost to corruption.

At any rate, there is a point in life where you personally need to protect someone else and your ability to do that in the "information age" is harder than it has ever been. So a silly sticker that makes teenagers scoff and parents happy fills every cup to the brim.

From a business point of view, they are generally regarded to be a bad idea. See various comments on what is now the main FastMail thread:

> some investigators (the senate oversight committee perhaps?) would review his evidence and shut down the illegal bits, and that would be that.

I think you are very optimistic about the way the United States and its various instruments handle complaints, respect the law and police themselves.

I am not an optimist. I think most nations are more interested in their material goals than ideological integrity. I also think that model is more consistent with history than the other.

After all - how would a government with such transparency and integrity let its armed forces fire on civilians to begin with?

If you read the report you would know that this is not what they are claiming. The report bases everything on a simple assumption - it will be much more expensive to own the car vs to have one rented to drive you to your destination.
Also the report talks mainly about the passenger cars, but electrifying semis and tractors is not really that unrealistic.
It's great, if they can solve the problem! My experience, as a kid who self-taught C after feeling that QBasic was too limiting, is that to debug problems, you often need to go a level or two deeper than the code you're working on.

As an example, I've encountered bugs with Python libraries that I had to debug using GDB. If I wasn't comfortable with C, my only option would have been to throw my hands up in the air and say "I don't know why it crashes sometimes"

Re: snobbery... maybe? I'm sufficiently self-aware to recognize that I have a lot of pride in the fact that I am comfortable pretty much anywhere in the development stack. Out of high school, I recognized that I would occasionally encounter software problems that appeared to be deeper in the system than I was comfortable with, so... I went and did a dual EE/CS degree.

At this point, I'm happy writing JS (React/Redux are my preference), and I'm happy debugging ARM machine code (I once had a peripheral fail to initialize because the gcc optimizer had reordered code such that I was violating the wait states on the periph). Glitches on the power supply rail? Bring on the oscilloscope. Shit performance in your web app? Let's profile it and see what's up.

So sure, I might be a bit of a snob about this. I put years and years of effort into deeply understanding all of this stuff. You want to hire a guy who knows jQuery and has never manipulated the DOM by hand? Go for it! And when the app is buggy and performs like shit, give me a call and I'll help you untangle the giant ratsnest they made.

Tiered support contracts are common in enterprise software. If the base level of service were bad, nobody would use the software, and that's clearly not the case here.

Agree; the "charging problem" is a huge obstacle for the electric vehicle industry.

We're going from a world where vehicles need to "recharge" (refuel) once every week or so for about a minute and a half to a world where they will need to recharge nearly every day for several hours.

Nevermind what happens to the electric grid when all this energy that was formerly being moved in tanker trucks in the form of gasoline now has to be moved over the grid and down to consumer homes.

I'm all for electric vehicles, but they have enough problems that any switch will be long and slow because we as a society will have to change the way we build and live in cities to deal with those problems (just as we did when gasoline vehicles replaced horses, so there's precedent).
