If you're interested in chip fabrication, I heartily recommend watching https://youtu.be/NGFhc8R_uO4 - it goes over the evolution of how they make transistors all the way up to 2009 state of the art, with a follow up talk in 2013 (https://youtu.be/KL-I3-C-KBk).

Both of them mention how Intel is sinking billions of dollars into ASML to try and get this process working, and how impossible everyone thinks it is, so I'm skeptical that they finally got everything squared away now :)
Cars aren't killing people. Car drivers are killing people, usually because they are careless.

Ah, that's a good point. So there's pretty much no way that any kernel code can be GPLv3, short of contacting each and every contributor and getting them to agree to switch.

How do you do that when corruption eventually seeps into everything given time? We’ve already seen it happen. You create regulatory bodies. At first they work. Fast forward a few decades: the people the regulatory bodies were supposed to watch are now in control of those reg bodies either directly or through heavy lobbying

I work on a college campus, and now the students are back. They are the worst pedestrians to deal with. Many of them are distracted on their phones, and many will just start walking into the road in any random place, never even looking if a car is coming. I would say the intersections are very pedestrian friendly - stop signs where they can cross any time (and I don't fault them for that), but please stop walking out into the middle of the street, or using the street as a sidewalk.

Appart from storage and video, there is just no need to go over USB 2.0. My brand new USB microphone uses USB 2 because there is no advantage at all to USB 3.0 for this device.
But why! It's so easy to find a distracted driver driving recklessly these days. Whether it's failure to maintain a lane, maintain a speed, or failure to signal you don't need a semi truck to enforce it.

Sure, K comes before P in the alphabet, but figuring this (and the actual distance) out takes a lot more mental effort than comparing 4.4 with 9.

It also resolves the issue where you need to decide whether 7 is larger than Marshmallow - a question that would make people question your sanity if posed without context.

And to make it more confusing, each release had a separate codename used before the release, so you had Android K, Android Key Lime Pie, Android KitKat, Android 4.4, and API level 19, all meaning the same thing.

Now, if only we could get rid of the separate "API level" designator (or rather, turn it into an opaque enum, instead of using it everywhere)... because 28 should not be less than 10.
It costs so much less to drive an EV per mile largely because we get electricity from sources with a much higher EROEI than present day oil. Gas, coal, solar, wind, nuclear, and hydro are all much better. The low energy return of current oil is priced in.

BTW it's not just obtaining the oil but refining it. Oil refineries use a ton of power usually from electricity, gas, or by burning some of the oil itself. Heavier oil like tar sands and shale takes more energy to refine, as does high sulfur oil.

Tar sands is so bad I've heard it described as being almost more a way of very indirectly converting other sources of energy into oil than a source of energy.
But similarly, one data point that DDG hasn't overtaken Google doesn't mean that tech people's preferences don't influence ordinary people.

I thought it was generally well-accepted that developers mass-moving friends and family off of IE 11 was part of the reason why other browsers ended up beating it.

Similarly, I thought it was mostly accepted that part of the reason so much of the web was optimized for Chrome was because Chrome had genuinely better developer tools, and developers preferred to optimize first in Chrome and second in other browsers.

Maybe there's more disagreement on those points than I realized.

Even on the subject of DuckDuckGo, which is probably not going to be mass-adopted any time soon (if at all), actual usage numbers are increasing faster than any other major search provider, including Google[0]. Whether or not those numbers are coming from ordinary people or tech people, clearly somebody is being convinced to use DDG. Is it going to be a revolution? Probably not. But it's not nothing.

I really wish people would stop defining success as a monopoly. Even in the browser space, the goal isn't to make Chrome vanish. We just want Firefox to have a big enough user-base across enough markets that it can't be ignored. Even 20-30% would probably do it. Mozilla doesn't have to kill Chrome.

Similarly, if every non-tech user keeps searching on Google, and DuckDuckGo just becomes a great search engine that every programmer prefers, that's a pretty big win. I would not call that a loss.

You don't need any "hack", right in System > Gestures > Navigation, all three options are openly available (100% gesture, 2-button + gesture, old 3-button style). I believe they intent on keeping it all available for sometime, if only for accessibility reasons.

Also, the charts show that it's either equal and better, and there's also the implicit fact that not showing buttons also means more screen space, so even if usability metric is the same, visually it's a win.
Could they then go and create a QR code to share/decode?

It’s tough to compete with free things like https://hatchful.shopify.com because social media logos are included and don’t cost $49.

Not sure if the result logos are intentionally blurry, but that definitely needs to be fixed. You will lose more business with the low quality results, than you will from people who make a logo and save the high quality version for free. People who are actually going to be willing to pay are going to be turned off by the bad result.

So when I was in primary school in the US in the 1980s, we had recesses. That is the golden age of those "highschool movies" -- and they were to some extent of course "fantasy" portrayals of high school even then, although not about the time between classes and recesses necessarily.

We also biked to school ourselves unattended. And we had maybe two half-days a year spent on standardized tests, one test each. The insanity of American schools is a more recent phenomenon.

It can vary between school districts though. Generally the wealthier and whiter the neighborhood/city/school, the better the kids will be treated. Although it's pretty shitty even at most of the "good" ones.

What you are reading isn't much of an exagerration though. It is a good reminder of how insane it sounds to you, because IT IS INSANE.

And you say we seem to be "fine" in the US? Have you even been paying attention to what's going on in the US? I don't know how much of it can be blamed on the eductional system... but you know, probably a chunk of it. The schoolchildren and former schoolchildren of the US are decidedly not "fine" though. This place is fucked up.

>renewable electricity has a short-run marginal cost of zero, is cleaner environmentally, much easier to transport and could readily replace up to 40% of global oil demand

Hmm, not sure about that "much easier to transport" part. A cube 3 meters on a side can contain enough gasoline to power the average car for its entire lifespan. The gasoline is a liquid, it is relatively easy to move it between containers. Any technology that is capable of moving macroscopic amounts of matter is capable of moving gasoline. You can haul it on a bicycle, you can haul it on an airplane. To transport electricity you need to make sure there are power lines and batteries arranged in a certain way.

The grandma stereotype is discriminatory towards both age and gender.
uh... really? you should get that memory thing checked out.

I too have absolutely terrible pre-uber experiences (in the DC area). If one was out drinking in DC, and needed a cab back across the river to VA, you had to hope the cabbie had the doors unlocked, because they couldn't refuse a fair once you got in and sat in the car, otherwise they'd just drive away if you told them where you were going. And it was "cash only". Which I later learned was a load of BS, when I had a $100+ fare for work, cabbie happily pulled out the old cc scanner complete with carbon paper... Things didn't get better until my roommate introduced me to his "driver". Which is was just a guy with a Town Car that I could call, tell him where I'm going and when, and if he was available, he'd quote me a price (there was no meter or anything). And then there was the stress of is the cabbie I called for going to show up in time to get me to the airport at 6am. Uber/Lyft crushed it for all these reasons, and if the prices need to rise a little, sure fine.
The example of a new company in Austin doing it's own little Austin thing is fine, but the other huge benefit of Uber is it travel. If I get off a plane in Europe, NYC, SF, small po-dunk town, whatever, I've now got a very frictionless path to getting myself some transportation. Don't gotta look up the local cab company, don't gotta mess with the local mass transit, all my billing info is setup and ready to go. Makes me wonder if everyone seemingly hating on them or wishing them harm is too young to remember how shitty things were before. On the "employee" side, I do know a number of people who drive for either or both company, but they all do it on the side, fwiw.
Honestly the electrification of farm equipment is coming too. For a tractor you want two things: weight and torque. Electric drivetrains provide both.

Tractors have way more complex transmissions(HST, Power Shuttle, etc) that all goes away with a VFD electric drivetrain. Large traction motors already exist(all cargo trains these days are diesel-electric). The lower operating costs and lower maintenance help as well.

If I could have bought our Kubota in an electric drivetrain I would have done it in a second
Yes, it's much much better. That one was unfortunately in a half-way between gesture and buttons and felt very unfinished. This one is much smoother and easy to quick switch between apps. It feels a lot more natural, and the bottom buttons are actually gone, saving space.
The solution to being bad at security isn't to establish quotas (that's a great way to make sure DevOps engineers get rebranded as Dev-Ops-Sec engineers, and not much else), but to get better at security.

Imagine if any other field said that. "Not burning people's houses down with electrical wiring is just really hard and we're really bad at it." "Keeping bridges standing is just really hard and we're really bad at it." "Flying across the country without killing any passengers is just really hard and we're really bad at it."
The main point of socialism -- broadly construed -- is to secure self-determination for the working class by ending the dominance of the capitalist class. Redistribution of money is just one possible mechanism that might be employed to that end. In that sense, it's no more "socialist" to bail out or give generous tax incentives to powerful corporations or wealthy people than it is "open source" (let alone "free software") to release source code under a restrictive license.
> Crystalline nets harvest water from desert air, turn carbon dioxide into liquid fuel

It's like we are stacking crazy, onto crazy, onto crazy.

You can't get water from air in deserts or places needing water of any practical, non military use - Here's a start - https://www.youtube.com/watch?v=EGTRX6pZSns

We don't need to turn CO2 into fuel, just make fuel/energy without fossil fuels that's also used, and you're solving global warming in a amazing way.

It's worth trillions, so it's always AMAZING to see some school kid or amateur scientist or researcher who just needs a little more research beat the multi nationals.

It's a shame the multi nationals are to dumb to not hire school kids and these smart ideas people. Just shitty people who spend years studying at university then years working in the industry doing hard work to gradually make change.
There have been too many conversations that I've been a part of that just get me frustrated due to how people think about owning or using credit cards. People are so paranoid about their credit, they drive themselves crazy for nothing. I'm not speaking about those who are in debt, but those who pay every bill on time and in full.

I can go on and on, but the bottom line here is this. People should take advantage of what credit cards really have to offer. Owning just one card is pointless in this regard. 1.5% unlimited cash back is nice for those who can't handle spending a bit more time actually making money and earning free vacations. For the rest of us, it's simply a waste!

I think everyone should at least be educated in what REALLY causes issues with their credit, and what they can take advantage of when it comes to credit card benefits. While this specific spreadsheet is targeted at beginners, it's wonderful for anyone who just wants a way to more easily visualize their past earnings and potential future earnings.

I've been working on this spreadsheet every so often, and shared it with a few friends. I even tweeted it, as well as included it in my blog posts on Medium. I figured even though it's not an app or website, it would be great to get feedback here as well!

The way its set up, is that it's a view-only spreadsheet that I made public. Anyone can copy the spreadsheet into their Google Docs account and edit their own version to their liking. The first sheet is the math, and the second sheet lists benefits of the credit cards I personally use and recommend.

It would be amazing if anyone who is into this type of stuff to let me know of anything you think is missing from the spreadsheet. Additionally, I would love to hear about what you like about it. My goal in general is to make certain aspects of personal finances easier for myself, and then of course for others.

> There’s an old saying that in America we have socialism for the rich and capitalism for the poor.

Yes, and it's an extremely dumb saying that only makes sense within a particular misunderstanding of what “socialism” means that derives from hostile mischaracterization by capitalists.

(Socialism about collective, rather than private, ownership of the means of production, whereas capitalism is about private ownership of the means of production. The rich in America very much enjoy the benefits of private ownership of the means of production.)
I agree with you about the asymmetry, which I was alluding to but didn't really spell out. I also agree with you that we are limited by our current software/network infrastructure and fundamental changes in that area may be necessary to get to a better security "story".
I have an easy solution to this problem. Make it a felony to use your phone (e.g. looking down at it) while in the driver seat of a vehicle in motion. This is the only way you will get people to pay any attention. You only have to enforce something like this occasionally. The fear of harsh consequences will take care of the rest. Drunk driving seems to be far less of an epidemic than distracted phone driving these days...
Drivers who are aquainted with you may make a modest wage, and I’ll wager you know no drivers in Minneapolis nor Orlando, for their mileage rates cause their rideshare labor to be an entirely charitable endeavor.
We’re really regretting going with MyBatis. Huge waste of time when most queries could be easily handled with Spring Data JPA.

Also now that we need auditing there’s a pile of work we could have have gotten mostly free with an Envers annotation.
I also think this is a pretty reasonable change, since it already requires users to edit files, so about:config is not really a major additional step.

But I also would imagine the usage was quite low already and any incremental hassle will push it lower and it won't be hard to get to an analysis where maintaining a rarely-used non-default codepath is seen as not worth it. Of course it all depends on what's going on with the specific code at issue, but the basic point of my post is that "nobody is proposing to remove this capability" is true, until it isn't.

This isn't a feature I actually use, but I also find the removal of a minuscule startup delay of a program I don't actually start very often to be a pretty marginal improvement, so I don't really have skin in the game in either direction.
It's a shame that we don't have the technology to pull energy from the sun and turn it into electricity.
