I find it amazing that Linear Regression in scikit-learn doesn't return standard errors/t-scores for the coefficients. (These can be useful for model selection, for example). I know about statsmodels and pysal, but the workflow with these is already slightly different.
> The big question is, given a particular student, will they do better with a college education?

Maybe, it's really hard to measure. I suspect a good not great college is a very good way to improve a particular person's life, but not the absolute optimal use of four years and about $30,000.

While this question is really important for individuals to ask, I don't think this question is going to destroy institutions of higher learning. I think a lot of people will still take the relatively safe path of completing a four year degree.
sure, but the problem is that there are no legitimately recognized avenues for doing so.

politicians won't want to be seen as "anti business" because they know who funds their campaigns. non-elected regulators are already captured, so there's no movement possible there. workers have no real power at present -- and, if they tried to exercise power anyway, they'd be branded as radicals without any legitimate perspective on policy. consumer boycotts are a thing of the distant past, and are unlikely to reach the size necessary to inflict the requisite amount of damage in any event. smaller competitors may be living hand-to-mouth as far as their businesses are concerned, so they're in no shape to take on social or economic change.

all of this is BEFORE we think about whether amazon is a genuine monopoly that threatens competition in rigorous terms. i'm of the view that it is monopolistic in its intent, but the existence of a plurality of options for any given commodity which it produces/sells makes it hard to build a case for it being a living monopoly if you're talking to someone who is pro-amazon or pro-big business.

I think you’re conflating an education (what you’re getting now) with a life experience (what you’re describing someone going to college is receiving).

I would rather pay for my kids to travel the world for a year after high school, and then educate them separately (similar to the education you’re receiving now, internships, etc), so they can have a richer life experience and hopefully a better education.

Selection bias, if you're starting a company at age 43, you are risking your career and monetary stability. The type of person who can afford this is probably already part of an elite financially secure class. How misleading is this article? They are comparing apples to oranges, people starting companies in their 20s are not the same as people starting companies in their 40s. Take the set of people in their 20s who would be capable of starting a company in their 40s (meaning they have career success, a cushion of money, etc) and compare them to the entrepreneurs in their 40s, then you have a statistic. This is false otherwise.

EDIT:

To further this thought, what I would truly wish would happen would be that A Tesla-like "drivetrain platform" were available to boutique shops who could build whatever type of cab they wanted onto a standardized system.

I worked with a guy in the 90s that took a Corvette Z base and put a 1938 ford on top of it.

I'd like to have the same be done with Tesla drive train bases - where you can have an upper made to fit the lower. Clearly, there would have to be safety standards to be met, so don't waste time arguing that point...

Thanks for the response! I can imagine how losing privacy would be extremely frustrating.

I played with an iPhone app[1] version for a while and was able to get moving pretty fast. It makes text input feel like a game. Also, I realized that a lot of the colors are customizable in the settings.

Looking into the project further, it looks like it was run by David MacKay's research lab (Inference Group) and he unfortunately passed away a few years ago. Will continue looking to see if I can find anyone still working on it. Most interesting innovation in input tech that I have seen in a while!

Im a professional engine mechanic for a small chain of service centers, and this reminds me of the hybrid race and the car manufacturers that had to scramble to make up for lost time. The only difference being it wasnt Mercedes and luxury makers, it was consumer giants like Ford.

Chevy and Dodge bet boatloads on the american consumers lust for the SUV even if gas hit $5 a gallon, only to find out just how wrong they were in 2008. Few people know this but Hybrid Synergy Drive from Toyota became the de-facto standard in US hybrid systems. every Ford hybrid licenses it, and many Nissan hybrids do as well. Honda developed their own hybrid system but as far as I know it was never licensed.

https://en.wikipedia.org/wiki/Hybrid_Synergy_Drive#Patent_is...

Now you have the Chevy Volt, which was half of Chevrolet pleading with shareholders and management to embrace electric, and the other half puffing on their cigars and chortling over "battery powered" cars. The result? some kind of design-by-committee plug in hybrid electric with a motor thats a generator? Needless to say the Prius casually crushed it.

Finally theres BMW with their i3, but who cares? A p75 will dominate it in terms of both power and range. Many mechanics I know attest that BMW could only bring this to market by building most of the car out of carbon fiber.

The glaring fact remains that everyone in the industry is back to 2005 all over again. pulling up their pants and sprinting to keep up all over again with something they all insisted wasnt going anywhere. My apprentice tells me Porsche's Taycan electric will do 0-60 in 3.5 seconds, but again, who cares. a P100 will absolutely embarrass any porsche model gas, or electric, in a sub two second quarter mile with ludicrous speed and still have enough charge to get something at the mcdonalds drivethrough on the way home.

Possibly because it was only discovered a century and a half ago and it's easily measured in the modern era? Plus, two hundred years ago it would have been "cold and tired all the time", which I kind of think was the default state for humanity.

As a German, where the car industry is really big, I have felt a little embarrassed for a long time that the German car companies apparently were unable to get off their asses and rethink the engine.

I remember 18-20 years ago, fuel cells got a lot of publicity, but nothing ever came of it. In retrospect, I think it was just a decoy.

Now these companies, that have been around for over a century in some cases, are facing competition from out of nowhere, and they behave like they were paralyzed.

It has been clear now for a few decades that in the long term, internal combustion engines need to be replaced. Car manufacturers appear to have been asleep at the wheel, so to speak.

If the industry is finally beginning to wake up, that is a good thing, but I am doubtful they will be able to turn around the ship in time. If they had started seriously some twenty years ago, who knows?

But I think it is too late now. It will take quite a while for companies that big to go belly up, but their fate is sealed.
Yes they might not be okay with that but airlines apparently can hold the passengers for 8 hours because of delays. To the point of toilets overflowing. I think if you run an airline, you are legally required to go out of your way to to provide terrible service.

> Such services are commonplace in the aftermarket parts industry.

Such services are available for the most common vehicles, not every vehicle. It also takes time to prepare, and if the market is small (Tesla is still a niche luxury car), then why even bother?

I know, I know, there are cities where it's a relatively common vehicle. That's not enough, it has to be relatively common on at least one whole continent.

It may become simpler in some regards (drive train with fewer moving parts) but I think you can take your mind off the "do it yourself" part. The SW and electronics are always proprietary with little chance you'll ever (legally) have access to them. If anything their situation will get a lot worse as "always connected" cars become more common. Most likely trying to change/mod anything there will be detected and trigger some reaction that could go all the way to flagging your car as no longer street legal.

And what's left for you to repair? The simplicity you ask for will be introduced exactly where these home repairs used to happen: oil, filters, spark-plugs, a hose here, a cap there, etc. But the rest of the car stays mostly the same or gets even more complex. Most mechanical parts that aren't touched by the transition from ICE to electric motor could stay the same (suspensions, brakes), while the interior electronics will become more or less the equivalent of today's smartphones. Too complex for most people to try fixing themselves.
This is pretty great. I have been wanting to get into FPGA programming so it's nice to know how low the "basement" price is for the essential equipment.

Panasonic can sell cells for sure, but not batteries. Tesla owns the batteries, Panasonic owns the cells. This is confusing because most people refer to "cells" as "batteries".

A "9V Battery" is in fact a battery, made up of 6 cells. But an "AA battery" is actually a cell (made up of a single cell of size AA).

Its important to remember the technicality here. An 18650 Lithium Ion Cell is made by Panasonic. When the cells are merged together with electronics (over-voltage / under-voltage sensors, charging, balancing, etc. etc.), that's when it becomes a "battery".

Tesla's biggest moat is certainly its "battery", the electronics and smarts that it uses to put cells together. But Panasonic owns the chemistry, so to replicate Tesla's efforts, other manufacturers will be able to buy cells from Panasonic and build their own batteries.

The question therefore, is whether or not other companies can combine cells in such a way that they are properly cooled, properly maintained, etc. etc. It seems possible for sure, but Tesla certainly has a headstart on battery technology. (But no "moat" on cell technology).

The New Organs: theories and realities of corporate surveillance
I have a few raspberry pis at home that I run a few Docker containers on, mostly personal stuff/tools/scripts/servers that I update infrequently but use a lot. Any software I write goes into a container, I like that abstraction.

I really want to reduce the friction between developing/maintaing something and deploying/running it.

Right now I just have a script for each service that stops the docker container, pulls the latest version from a private repo and starts it again.

But that "solution" is getting cumbersome to manage as I add more containers to run and I have to remember what Raspberry Pi each container is running on if I'm running a service that I don't need to have on 2 nodes.

I tried to learn Kubernetes a few weeks ago by installing it on one of my Pis, but I quickly realised the learning curve was way beyond what I wanted to be spending my time with (right now - I realise this is a feeble excuse) - especially for home stuff sitting behind a private network.

I've been looking at Docker Swarm recently instead which looks a lot simpler. Maybe it will be a good stepping stone to grokking Kubernetes.
The Netgear Nighthawk series is almost always available on Amazon and is generally well supported by dd-wrt.

Specifically, the best deals can be had on the oldest model, the R6700v3, from an Amazon warehouse deal for $70. This is what I use, and it works without issue with dd-wrt. You'll need to flash it 3 times.

The best device is probably the R7800 model. It uses a very fast, non-Broadcom (OpenWRT-supported), modern chip. The only way this matters in practice is if (1) you have a gigabit Internet connection and (2) if you need QoS turned on for scoring an A+ in "bufferbloat" on speedtest.net--i.e., you play games.

If you don't use QoS, you will be able to serve 1 gigabit with dd-wrt's "Shortcut Forwarding Engine," which is an accelerated "in-Linux-kernel IP packet forwarding engine." If you don't have a gigabit connection, the typical Linux routing stuff that dd-wrt uses is fine.

With regards to model roulette, you can always buy it off eBay for the specific model. These routers are so common I see listing for them in Craigslist in the Bay Area right now.

I would argue the two main reasons to do this are for improved security/stability and QoS. If you're not interested in these features, buy something that Wirecutter recommends in your price range. But compared to $70, I believe a truly decent router can be had for $50 (the Archer series others have mentioned) that is also truly ancient.

The Apple Airport devices run ARM NetBSD and you can SSH into them. The last generation ran NetBSD 7 and executed binaries from NetBSD userspace when compiled statically.

OpenWRT does not ship closed-source Broadcom drivers, so it tends to have worse support across the board. I don't think their OSS-related reasons for doing so are material to you.
Not yet... I bought a brand new one just for testing with OpenBSD vs Vyatta because I'd like to benchmark performance of each.

Web: write once, run everywhere, the user is guaranteed to have the runtime installed.

This is damn hard to beat, even with other reasonably written multiplatform toolkits like Java FX or Qt.

Also, a web page is its own environment, not intended to blend in. With "native" apps, there's always a bunch of "...but not native enough" complaints. (My idea is that some apps should explicitly aim to look alien and their own, without making attempts to fit in, like e.g. Photoshop or Blender do.)

With Java FX, you have to have the user install a recent JRE. With Java 9, though, I suppose you can make one fat binary with only the relevant parts of JRE and you code strung together, and the rest removed. (This has security implications, though.)

Qt means C++ which is a pain for many reasons, or e.g. Python which is a pain to distribute, though this can be alleviated (pack everything into a single fat binary). You still have to have a build per platform.

I just suppose that Web tech expertise is easier to come by, and a Web product faster to produce, at least initially. This trumps great many reasons from the business perspective.
