If the headline was "Man lands on the moon", would you complain that he used a rocket ship instead of jumping?

The way this headline is written, it's as if they'd written "Armstrong jumps to moon", and neglected to mention in TFS that he was jumping from the ladder of the lander to the surface. TFS says "managed to 3D print, and assemble an entire automobile", and that's misleading to the point of lying.

It's a cool, impressive, incremental achievement, but they haven't landed on the moon here. And tech reporting, and tech in general, would be better served by accurate reporting of it.

Yep. MOOCs don't serve the important part of the teacher's job. Teaching is best as a dialogue. A videotaped lecture is little different from a book, in that the information is fixed; worse, unlike a book, you don't even get to read at your own pace. It's not without value, since some things adapt well to that and different modes work for different people, but it's still missing the two-way communication that a real teacher provides.

People have pushed MOOCs largely for the learn-a-bunch-of-facts classes, such as science and tech. Technique is also a "fact"; it's stuff that can easily be tested and graded. The things that are missing are the parts that make us consider a student well-rounded: history, literature, sociology, art. These sound trivial to nerds but they're about innovation and communication. They, too, have to be practiced, and it's not something that can be memorized. Even the STEMmest jobs are ultimately about people: seeing what people want, finding ways to tell them your ideas, building up a story together. And that's something that a real teacher can help with, and a videotaped teacher can't. (Nor can a videotaped teacher answer questions or ascertain just why a student isn't "getting it". Even a "great teacher" is little more than an actor when on video.)

Teaching is too often undervalued as if they were just handed a book. It's a skill of its own. We STEM nerds often undervalue that skill because it's not easily graded on a multiple-choice test.

Do yourself a favor; avoid the hostile Latvians at Mikrotik and use UBNT's Edge Router! [And hey, I've got nothing against Latvians - a colleague is Latvian and the nicest guy ever. Dunno, perhaps it's something in the water, but wow Normis is out there - as are most of the other 'Tik guys.]

Seriously! The feature set of EdgeRouters is pretty full and there's nothing I can't do on ER that I could [and used] on 'Tik.

Plus you get a real Linux underbelly - if you can't do it in the CLI, you can probably find a way to do it in Debian.

Seriously. I've used Mikrotik (hostile latvians [check], and buggy firmware [super check] - really the rant list is too long to enumerate here!) and am moving lots of stuff to UBNT.

The edge-router line is frankly totally incredible.
And speaking of VPN - they have an OpenVPN that actually supports the full spec, rather than the totally neutered one 'Tik does.
Real IPSec firewall interfaces! [L2TP where IPSec can get bypassed? Another 'Tik exclusive!]

(Do I sound kind of bitter about 'Tik? :) Yeah, I've got quite a number of people on 'Tik stuff, but given their hostility [it's legendary] and crap firmware [firmware russian roulette anyone!?] and a host of other issues - I'll be glad to have all my clients off onto Ubiquiti's stuff. )

Learning curve is steep, but no more than equivalent products - for example 'Tik, Cisco etc. It's a Vyatta based platform. UBNT's forum is incredible, as are UBNT staff themselves.

Virtually any UBNT product I'd not hesitate to buy. It's *incredible* value.

As for a router on a PC or some other idea...
It's way less power than a franken-PC.
Solid-state disks. [less mechanical failure possibilities]
Massive packet throughput. [1M pps for the $100 ER Lite, 2Mpps for the 8 port versions!] Based on Debian. Rocks.
Damn cheap!
And best of all. Really pretty easy, quick.

Basic stuff won't require a lot of work/time. If you want more, pretty much the sky's the limit. But more fancy stuff will take more time.
But basic functionality - probably a couple of hours start to finish.

Good luck!

Good for you, man. I'm glad to see it happening. I don't like having publishers as arbiters of public taste any more than you do. I just think it's important to recognize that the vast majority of self-published ebooks aren't very successful, and it's not just the bad ones.

Taking into account, of course, the fact that you have to do all of your own marketing. You have to make your novel stand out among zillions of other indie ebooks, all of which have the same low barrier to entry.

Just having a major publisher's name on it is pretty substantial marketing. Even more so if they go to the expense to print out a physical book, which is a large sunk cost up front. That tells readers that somebody believes in the book, to the tune of a few tens of thousands of dollars. And that publisher will generally get it into meatspace bookstores, where your book has to stand out only among a far, far smaller crowd of other physical books on the shelf.

It's not impossible to do very, very well with an ebook. But much of the time that additional 45% you get to keep is 45% of a much smaller pot. (And generally the margin is much wider than that, in fact. Going rate is usually in the 10-13% range, in my experience.)

The way I see it... if you can get a publisher interested, you probably should, at least until you have a large fan base of your own. It's the easiest way to that fan base. Building it up yourself is difficult. Not impossible, and possibly no harder than getting a publisher to take an interest in you. But if I had a publisher on the hook, I'd keep it.

There is a certain amount of lock-in to the film incentives, especially for TV series. Shooting a film requires a substantial amount of infrastructure, both personnel and equipment, which doesn't exist everywhere. These people are often not employed by the studio directly, but form local service companies. And where those companies exist, it's easier for more film projects to move in.

Even if Walking Dead were to pack up and move, Georgia may still have accomplished its goals with the subsidies. I know that Maryland is similarly pushing this. They developed a lot of that infrastructure a while back during the filming of Homicide in Baltimore, and there have been a lot of follow-on projects. They're now trying to boost that with House of Cards, which is an enormous undertaking that employs many hundreds of people (at least part time). The resources of material and knowledge built up in the local economy attract other film projects that can do the job faster and better because it's already here, rather than building it up from scratch.

Of course, producers know that, and will drive up the price as far as they can. Maryland nearly lost House of Cards in a kind of game of chicken; neither side wanted the production to move but each wanted to get a better deal. In the end, House of Cards largely won, and people in the local film industry are extremely happy about that. I don't know if it's really a good deal for the state in the end, but at least for the moment it's employing a lot of people, and since it's a series they'll go on having work to do for a while.

Interstates are the perfect place for it: relatively few surprises and extremely boring for drivers. They're all "limited access highways", so you don't have to worry about pedestrian crossings or children running into the street.

If they just left it at that, I'd consider it an enormous advance over the present state of things.

That's kind of an interesting thought: a new market for storing your phone close enough to your device to work but not necessarily accessible.

My first thought was a kind of belt; I use something like that to hold my phone when I run. But that would ruin the line of most dresses.

Next thought... a garter? It wouldn't fit under close-fitting pants but it would fit under a dress. It could even be a kind of fashion accessory, in a "Oops, I showed you my phone, how naughty" kind of way: make it frilly or colorful. Getting it tight enough to hold a heavy phone securely without cutting off circulation would be a challenge. I never did figure out how it was supposed to work on the upper arm, but people make it work.

I'd gotten the impression that it was a bit larger than that, though I really can't say why. The film version of the Quidditch World Cup showed tens of thousands of people. One can assume that it's practically everybody, so perhaps your guess is low by an order of magnitude, but it's still roughly in the ballpark. A few other numbers I ran also put it roughly in that area.

The thing with Snape's potions research is that he never showed his work. He scribbled notes about improvements, but never seemed to establish any kind of theoretical basis for it. That seemed on par with the rest of wizarding practice.

That kind of makes sense for her notion of a pre-scientific world that shut itself from society about the time of the Enlightenment, due to oppression. But they never really seemed to feel the loss, and I think that they were missing something important. The Wizarding and Muggle worlds had a lot to offer each other.

The graph includes the cite, so you can check up on their methodology. The sample size is 5,000, which is actually pretty good for a sample like this. (1,000 is more common, with a 3% margin of error, though since they're breaking it down into three roughly equal subgroups they'd need a larger sample.)

Most people will listen to your unreasonable demands, if you'll consider their unacceptable offer.
