I agree with your first part that a Masters in Education is a hassle to get, even if you are currently a teacher during the day plugging away at night school to get the degree. It's a lot of sunk time (and money if you don't have it paid for somehow).

I'll disagree that it's any benefit to job performance. Any evidence that it is indicative of other job qualifications is very limited. It's telling that the first page of google results for "benefits of a masters degree in education" are mostly about how it can improve the teacher's salary, not how it makes one a better teacher.

Master's degrees for other liberal arts degrees don't bring any salary boost.
I did most of my lower division at the local community college. At the time it was $11/unit for residents, and when I transferred to a 4 year school they told me I was probably better prepared (having had teachers that were there to teach that material).
Agreed. You are way more likely to get that raise if you show intent to leave by having an offer on hand. You can play the "I want to stay, but I have this great offer..." card and see if he bites.
The URL of that link is a pretty surprising thing, in and of itself.
You'll find a surprising amount of it will simply disappear. I'm at the point where I removed my models and collections directories entirely; since the only feature they provide me at this point are getting data from the server (which I can do with just jQuery, superagent, etc.)

six hours, is only 3600 minutes

You mean 360.
You could argue that those stats are a reflection of a mature company with the license model. When they were in a similar position to many of these SaaS companies we are discussing, their license fee and customer acquisition cost were enormous. That automatically self-selected their customers to be large enterprises, who they were completely dependent on. The initial license fee is such a large proportion of LTV compared to maintenance fees. With SaaS, companies are banking on scalability, personalization (multitenancy), and less sources of friction. Establishing a successful SaaS company allows them to realistically chase the long-tail of SMB that single-license companies cannot scale to do effectively.
Really? That's very exciting!
If recruiters at companies are afraid to have to defend their decisions on whether to hire someone or not based on their personal facebook account, then they shouldn't snoop on applicants facebook accounts.

It's just so moronic that I hope GP is an exception and that most recruiters doesn't give a shit about facebook.
tell that to my Java server that talks to .Net. IMHO you should channel it off and allow for German, French, Spanish, Swedish etc rooms. Closed minded to only have English speaking.
In theory it could remain flat, but you would only expect that as a precursor to bankruptcy.
Here are some constraints that I can come up with in a minute of thinking.

1.) Land costs. If you are building inside a major city land costs are huge, and you need acres of land. Outside of cities can be less expensive, but it's still a steep cost.

2.) Permitting/regulations/etc. I have no idea what it would cost to get the land you just built zoned to allow you to build a school, but I'm sure it isn't cheap or easy.

3.) Infrastructure costs. You have to build each of these new schools. The private boarding school that I went to[1] just built two new dorms after receiving a gift of $10m to house 98 students. They are probably really nice dorms, but it's not cheap to build. And that's just the dorms. You also need an academic center, library, gym, and possibly support buildings (like faculty housing, student centers, etc.). You also need to build roads, sewers, electricity, etc.

4.) You need to find and hire administrators and teachers. If you go with the chicago stats cited above then you'll need to pay each teacher ~$70k. One of the best things about private schools is the high teacher to student ratio. My biggest class was 14 students and most were in the 6-8 range. It's complicated to figure out the exact number of faculty off the top of my head, but you'll need at least 10 teachers. My high school had around 380 students and they have more than 60 faculty. So, for 100ish students you'd need 15ish faculty. That's $1m a year in funding. Chicago spends roughly $12k per student, which would cover faculty costs, but...

5.) You also have to pay administrators, janitors, lawn care, and a ton of other providers for service. Chicago administrators make roughly $120k a year. That difference has to come from somewhere.

6.) Oh, and you have to get accredited somehow so your students would be able to get into college.

There's probably plenty more constraints that we could come up with. But the biggest one is cost. Who is paying for this? A billionaire could do it, for sure. But it doesn't seem like people are upset enough about the current situation to pay more taxes to support the schools we do have. I'm not sure how you could convince people to pay to create a private school from scratch...especially if their kids aren't going to be the ones eligible to go.

> Have you used a vehicle powered by natural gas? I have. For safety reasons, in many places you have to get out of the vehicle while it is being refuelled (the cylinder gets really hot!). And that is a change from your 50+ years driving habit. It also takes longer than a comparable gas pump (even if it is measured in single digit minutes). The gas gauge also reads differently (my guess is due to pressure decreases as gas is consumed).

In India, people convert their gasoline based cars to use gas cylinders. The replacement is infrequent and doesn't need to happen as often as much as filling up gasoline.

Hardly. Jews that did not believe that Jesus was the Christ condemned him; Romans that did not believe that he was the Christ executed him.

Interesting - if I'm reading that correctly, Tesla's battery-swap technology substantially boosted the amount of ZEV credits they obtained and could resell by allowing them to claim "fast recharging", despite the facilities to actually swap batteries never actually being available to customers.
No answer to your question but I'd love a Puch Maxi style moped. They're not popular in the UK; and they're expensive; and you need to pass some tests.

An electric Puch maxi would be amazing.

My biking history: Started with a handme down Yamaha Passola, then a handme down puch-maxi-clone, then an abandoned converted Honda 75cc, and then I went to a moto guzzi v50mkIII (a 500cc motorbike) with a sidecar. At the time you could ride that with L plates without having to take a test. Looking back now it was a stupid thing for me to do.
If only Stripe served the whole of EU already.
> Fuel cell vehicles have never made any sense.

The only reason for me to get an Electric Vehicle is the green factor. If instead of my car polluting the environment, there is an increase in say coal factories, not sure how that helps the environment. So there is a need for fuel cells.
It's also important to address Customer Success Costs. For single-license model companies, all the costs are front-loaded into customer acquisition. For subscription SaaS companies, the product & overall service needs to be continuously improved in order to retain customers. For this reason, it is not uncommon for these companies to release updates at a very frenetic pace not seen in the older style companies.
That's the standard rule of thumb, that your cost to your employer is roughly double your salary. Of course it depends on tax rates, insurance rates, quality of benefits, etc. But if you are just estimating for a company you don't have much knowledge about there isn't a much better number to use.
"lectures may not exist in the future"

What would I listen to in my car streamed by bluetooth from my phone? Radio? No way.

What might happen is someday, someone is going to record "The Ultimate verbal explanation of a PDA automata" or whatever, and then for the next 500 years that'll be The One that everyone listens to. It hasn't turned out this way in books because of legacy analog media combined with desire of publishers to maximize profits. Imagine if you could just download the Feynman lectures on physics. Aspects are out of date, but still going to be better than the local talent.
One does not often hear about the warts of Erlang. What do you name those?
The problem is that it doesn't scale complexity-wise. You miss a key point with imports: A `<link>` imports something into the global scope. There's always one global scope. In my example, I was able to rename Toolbar into MyToolbar and use it in my scope. You lose so much using the DOM as primitive and JS as artifact.

And the second you start doing conditional elements (like the tabbed example), Web Components gets pretty complex. In React, it's just `if(shown) { renderItem(); }`.

If you make HTML smart enough, sure, you don't have to manually wire up anything. But then you're left with `x-if`, `x-ajax`, and so on tags. Why not just use JavaScript?

I envy you for being so well-adapted to the traditional style of teaching :) On the whole, most people learn better by listening or interacting or doing. I'm certainly the exception in this respect. My brain processes information much differently. It takes me 3x longer to process a sentence read aloud as it would to just read it. Lectures felt like a huge waste of time.

But do you really think that a lecture can cover material as thoroughly as a textbook? In my experience, lectures were supposed to cover part of the material (perhaps some of the trickier parts), but could never be treated as a substitute for reading.
glad to see the matrix is coming online smoothly
Agreed. Good management doesn't bother me about every little change and gets the customer to appreciate what we can actually deliver.
Actually, I live in an apartment so no plug there[1] and certainly none at work.

If Toyota goes hydrogen, there will be stations. They can push the tech just as well as Tesla is pushing recharge stations.

Great question. This is a very real pain point with dynamic content in today's world of bots / crawlers. Many sites right now are completely or partially invisible to crawlers.

As you point out, pre-rendering content is the prescribed way to solve this and there are some existing solutions (prerender.io, brombone, etc.) that are a good start, but this is still a confusing / hard problem for people to solve when they'd like to focus on building their app instead.

So we're keenly looking into how we can best integrate with these sorts of services or provide our own solution as part of our hosting offering. Stay tuned!
Agree. I didn't go to a single lecture after 2 months at university (electrical engineering). My TA was shit as well - was too tied up in computer vision research and found us inconvenient. However we formed a club (5 of us who actually gave a shit) to work through stuff as students. Rather awesomely our digital electronics lecturer turned up after a couple of weeks and helped us with stuff and had a weekly rant about how useless the other staff were. I think we helped him vent too.
That's the problem, transplanting physical world directly into somewhere that analogies don't work.

Too little, too late (imo). I'll think about it again once they have visual studio and all the good things running on *.nix.

Could benefit from using the word in a sentence. I could not understand what word it was trying to ask me to spell (and then it didn't help when the voice recognition of the letters was terrible and slow).

Good idea, but rough on the execution.
You are correct that both fit in uop cache, but I think 'userbinator' is correct here that loop unrolling is of very limited benefit here (and almost everywhere else). Because of speculative execution, processors are basically blind to loops. They will keep executing ahead along the most likely path even if this means they are simultaneously executing different iterations of a loop. The loads will pre-execute just fine across the loop boundary. While there are cases where reducing the amount of loop logic will speed things up, it really can be done in hardware!

I wouldn't take the risk of confirming the value of products. Take the example of sneakers, there are plenty of knockoff sneakers on the market. You can usually tell, but if you aren't in tune with that market then you might well sign off on a pair of fake sneakers and become responsible for allowing a fraudulent transaction to take place.
I prefer book to lectures, but whenever I skipped lecture the learning for exam was much more difficult. I do not really know why. I rarely understood things directly during the lecture, I usually just wrote notes. However, just being there and listening made learning afterwards easier.

I usually also got better grade, maybe because I had clearer idea about what lecturer focused on.

Video lectures on coursera were much more effective for me then live lectures. The difference was in speed up, slow down, rewind and stop buttons of course.
Frameworks decrease LOC, which drastically improve readability. Any shorthand variables decrease readability. Frameworks are great at enforcing these rules.

It's not, but you can randomly choose an equally-sized comparison group from the population who apply and are not selected.

Now you are changing the stated starting conditions. The plan is based on admission by lottery. Period. What other, selective private and charter schools do in admissions is irrelevant.

Scala is great no matter what is the "true" answer to the question "is Scala too complex?".

If it's indeed too complex for the mass average developers, then I can use it to filter them out. I got a free way to hire better developers (I don't have to use Scala in production in order to use it in interviews...)
Also if you do find a top developer who managed to master Scala's complexity, then the complexity is no longer a problem, it becomes a benefit, and they use it to create better libraries and APIs for the "regular" developers to use with more ease and type safety.

If it's not complex then I can easily hire any decent Java developer and provide Scala training (I think there is no argument that it's more productive / expressive than Java*, and remember in this "scenario" Scala is not more complex to learn than Java)

Win win

Now the real issue is compile times. If anything itches me toward trying Kotlin is having way too many coffee breaks (http://xkcd.com/303/)

You can have on-site production at the gas station though, which you can't currently do with natural gas or petrol, so rolling out pipes may be unnecessary.

"Have you used a vehicle powered by natural gas?"

I do believe we are talking about hydrogen fuel cells and hydrogen doesn't seem to act as you describe.

"the only thing preventing one from filling up a tank the way they do with gasoline is battery technology"

Yep, and every year it will be solved next year. I am hopeful but not certain.
Another way that we have used timeseries with Redis at Leftronic is ZSETs. The "score" is the timestamp and the key is a string like {"value": 42, "timestamp": 123456789}. That way you can have auto-sorting/replacement/insertion of timeseries points. Including the timestamp in the key is necessary so you can have duplicate values.
JAK is actually misleading in their marketing, in reality you pay a "loan fee" which corresponds to 3-4.5%/year, which goes to salaries etc. The only real advantage to a "normal" bank is that this rate isn't (directly) market controlled.

> no cloud storage (unless you buy your own)

That's kind of the whole point, isn't it? It's clearly meant to be a Dropbox replacement not for everybody, but for those who consider the lack of mandatory cloud storage a feature. So yeah, technically more a replacement for BitTorrent Sync than Dropbox, but not everybody knows about that.

Missing features can be added. Mobile clients by third party devs will surely crop up if/when this thing gets traction. The protocol is open, after all.
Parts of Microsoft have been using github for quite a while now:

The Azure SDK has been there since 2012.

I agree that even now it still seems kind of odd when Microsoft embraces open source technologies, and the company is very big so their support tends to be oddly lumpy (generally better among the groups working on products that are directly related to networking like ASP.NET, Azure, etc) but they've been on this path for quite a while now.
The Scratch I knew from a while ago was built on Smalltalk, and in fact there's an updated version that runs on Pharo Smalltalk, called 'Phratch'.

TFA says "PM is an attack ... and this is a consensus of the IETF". On the other hand, IETF continues to employ NSA employees (like Kevin Igoe, a co-chair of Crypto Research Group under IETF[1] ).

So: is it a consensus or not? Does Mr. Igoe consider PM an "attack", even though his own employer does it?

I'm having trouble reconciling the two.

Correct. The vehicle only needs to be able to swap, without the need to deploy the expensive ($~500K/each) battery swap stations.

Electric vehicles are more efficient well to wheel than gas engines, even if powered by coal plants.

This is well worth trying, but not directly applicable to reading from a file. This would help if you were allocating a buffer with malloc() and you wanted it to be backed by hugepages. But if you have control of the source, you are probably better using MAP_HUGETLB with madvise() or mmap(), or using the get_huge_pages() directly instead of using the LD_PRELOAD.
From the original paper:
"The effect sizes indicate that on average, student performance on examinations and concept inventories increased by 0.47 SDs under active learning (n = 158 studies), and that the odds ratio for failing was 1.95 under traditional lecturing (n = 67 studies)."

Averages are not a very comprehensive measure for efficacy in a teaching environment. I am glad they included the failure rates too, but people here should not be so quick to jump to changing out the entire methodology based on two numbers. Different students learn differently, and ideally you would look at the distribution in student performance for different balances of teaching methods.

Having said that, they are onto something.

Electric cars IMHO are missing the point, which is to get off fossil fuels. When you switch to an electric vehicle you are just shifting from Gas to Coal. The US still relies heavily on fossil fuels to power the grid.

My question has always been: Does shifting from gas to depending on the electrical grid actually help? Or are we just smoking cigars (or e-cigs) instead of cigarettes?

Also, what is the downside to collecting Hydrogen?
Yes! We're planning to integrate as many payment options as possible so this is definitely in the works.
