Eyeballing it, the pre-tDCS trend is relatively flat compared to the tDCS period. A t-test is wrong, of course, but I would be fairly surprised if a more appropriate analysis estimated a much smaller improvement. (I can't try anything because the Excel spreadsheet he provides only includes averages in ad hoc formatting, while I'd much prefer the raw per-round scores contained in his Brainworkshop's data/stats.txt file.)

> The general idea that we can "unlock" more brain power by simply applying electrical currents to the brain is utterly silly.

You might as well argue against the concept of 'stimulants' with that argument... The brain is an adaptation-executing organ which (among other things) seeks to conserve resources, which may not be the same set of trade-offs we would prefer in a modern environment.
This should’ve been the foreword. I respect those who learn from teaching.
> "now you can eat nothing but Soylent!"

Why is the message that it is build that you can do that a problem? (If I were to use it as a temporary replacement food I still would like to know that I don't have to take particular care to fix specific things it is missing. One less thing to worry about.)

That said, I think the customer base they are aiming for (and getting) right now is the right one for the moment (somewhat reliable demand from those that stick with it, willingness to tolerate hiccups, willingness to talk about it, ...)
People with egos and poor social skills abound in many tech companies, unfortunately. I think the sociopath label is applied too liberally, meaning you were probably dealing with a plain old asshole (real sociopaths have real social skills and make you like them so they can better manipulate you).
I wonder how this compares to nVidia's commercial GRID product[0]. They claimed latency up to 150ms from their recent announcements. I'm sure AWS can spike to worse than 20ms.

Either way, I still think adding latency will poorly effect certain types of games: online/twitchy ones predominately. It's cool how easy it is to set something like this up on AWS, though.

The Kindle DX is a great device. I have one; it's the Kindle made for serious readers. It needs overhauling and improving though. Sigh.

I don't know of any good ereaders through.

That's what keep sneezing or Kindle. Not having to fiddle and accidentally leave my place if I set the book down, being able to get a new book almost instantly, being able to look up words I don't know keep using the Kindle despite all the software/hardware faults. Not having to fiddle and accidentally leave my place if I set the book down, being able to get a new book almost instantly, being able to look up words I don't know.

But the absolute best is progress syncing. I don't bring my Kindle in less I know I'm going to need it, but anywhere I get stuck I can pull out my phone and pick up the book I was reading right at my last position. When I get back to my Kindle it already knows how much further I read. It's like hav when I get back to my Kindle it already knows how much further I read. It's so much more convenient than carrying a physical book around.

Especially large/long books. I read King's The Stand last summer. I'm glad I didn't have to struggle with the 1,200 page physical edition.
Wow, this is so incredibly cool. As a big fan of OnLive, I saw a lot of potential in the approach being used for making old school classic games available remotely, without you having to manage to keep them around locally.

It's really neat that you can do this yourself, and seeing the costs as low as they are is pretty encouraging too.

Nice job!
It's quite neutral. I find people who haven't taken protein shakes or the sort usually have the biggest issue with the taste when it's really not that bad.

I consume my Soylent warm so it breaks down easier in a shaker bottle and it works well for me. Been using it for six months now to replace my meal while at work.

I was told from a very early age that I was going to be something special. I tested into Gifted Education in elementary school. I tested into the best public magnet school in Philadelphia.

The whole thing began to unravel in High School, really... got a "No Credit" for an extra-curricular college course, had to retake a year of Geometry, barely made it through High School Trig. But, I went to college to study Computer Science. And failed out. Failed the same Intro to Pre-Calculus class seven fucking times in three semesters. (Half-semester course.)

I took a semester off, and enrolled in a local community college. Changed my major to English. Graduated with a BA in 2008, in the middle of the economic crisis. I didn't have any Internships... couldn't afford to take one as I was working to pay my way through college part-time in the evenings. Got a shitty telemarketing job for the benefits, got fired, spent a year out of work, worked for the Philadelphia welfare office for a year and a half, and quit.

I lucked into a startup job as a Community Manager, but the environment was borderline abusive, and beyond the border unethical (buying lists of email addresses for their target market to add to their mailing list and calling them active users in fundraising presentations). After getting fired/quitting, I found a decent job doing Web Production for a speciality publishing company.

I'm 31, in debt up to my eyeballs with student loans, barely making ends meet, and working a job that offers no challenge and little opportunity for advancement. I have personal projects where I can get some joy, but it's hard to find the time to do those when you're working forty hours a week, with an hour commute each way, and seeing a huge chunk of your cash go towards paying off the creditors for your borderline useless degree. If I didn't have my self-taught HTML and CSS skills, I'd never be where I am, so that's something.

I still feel like I should be further along because of all the pushing I was given as a kid. They told me I'd change the world. Instead, I'm just some underemployed schlub. I'm not about to jump in front of a train, but for those kids with more pressure, I can't blame 'em.

Wow, that got long.

I came here to say this. I absolutely love the device and have never been bothered by fully justified text. (My major complaint along that path is books can still override the font settings. Grrr. )

I also wonder if the author knows there is haptic feedback on the buttons and that the activation pressure can be adjusted. With minimum pressure and maximum feedback there is no strain on my fingers even after 8 hours of continuous reading. I do have strain issues with my fingers so I should have had a problem with it if that was the case.

I only got to level 4 before I decided to cheat and write a solver.

On game four there's an 11 step solution but it says the fastest possible is 13. The steps, in (col, row) form, are:

4,1 / 3,1 / 2,1 / 1,1 / 2,1 / 2,2 / 2,1 / 3,1 / 2,1 / 2,2 / 2,3

Level 13 says the fastest is 14 but a 12 step solution is:

1,3 / 1,4 / 2,4 / 3,4 / 3,5 / 4,5 / 5,5 / 5,4 / 4,4 / 3,4 / 4,4 / 4,3

Level 14 can be solved in 21 steps, not 25:

1,3 / 2,3 / 1,3 / 1,4 / 1,5 / 2,5 / 3,5 / 4,5 / 4,4 / 4,3 / 5,3 / 5,2 / 5,1 / 4,1 / 5,1 / 5,2 / 5,3 / 4,3 / 4,4 / 4,5 / 4,4

Level 16 can be solved in 14 steps, not 20.

Level 19 can be solved in 12, not 14.

Level 23 can be solved in 15, not 17.

Level 30 can be solved in 13 not 15.

It then told me that I need at least 26 perfect solution to unlock level 31. Which is annoying since none of my solutions are worse than what it expects.

I can see how it's a challenging game, and I'm impressed by how just a few squares can lead to so much complexity. But whoever coded it should have allowed for the possibility of someone beating the presumed best score.

I think you might have a defective unit, the touchscreen on my Paperwhite works reliably.

That said, even when it works perfectly it remains inferior to the simple shoulder buttons that the older kindles had. I hope Amazon brings them back on the next Kindle.

And those "touchstrips" on the Voyage are indeed infuriating. If anyone is in the market for a kindle then by all means save your money and stick with the Paperwhite.

I used to keep a horse at the horse barn on the Stanford campus, and I've met many Palo Alto high-achieving high school kids there. I asked a group of high school students, mostly from Palo Alto High School, who were discussing grades "What's considered a good grade point average now", and was told, in a bleak voice, "4.5".

Some of them thrive on learning. They show up back at the barn, years later, after graduating from a big-name college. It's tough on the ones who aren't quite bright enough for the selective colleges but have parents who expect that level of achievement. I've seen the pain in some who know they're just not bright enough.

It's getting worse. Suicides for Paly and Gunn students (those two high schools are the closest to Stanford) have been climbing since about 2009. I knew about the five suicides from Paly, but didn't realize it had reached the point that there are now guards watching the railroad tracks behind the school.
Thanks for posting those tables.

The thing I was surprised by is that the preferred stock had a 6% dividend. Is that common nowadays?

Back around 30 years ago when I was at startups, the preferred didn't get any dividends. It existed to allow the VCs to stay ahead of founders/employees in case of IPO, liquidation, etc. Not to collect a dividend along the way.

Your assuming you can send colony probes at more than 10% of the speed of light. IMO more reasonable assumptions push colonizing the milky way out to 100+ million years.

Honestly it seems like people look at light speed the same way they look at markets and forget there are numbers below 1%. There are several ways to get a small probe up to fairly high speeds but slowing down is a lot more difficult.
I didn't see any place where this method was claimed to be a magic bullet, or even a more common silver bullet. In fact, the author specifically mentioned this:

> excitedly participated and absorbed the entire material. The
> three other students' eyes were glazed over from the very
> beginning, and they did not seem to be involved in the class at
> all.

That's a very clear explanation that this method didn't work for every child in the class. In any class there will be children that are difficult to reach. This isn't necessarily an article about that.

In my particular case, every workplace I've worked in over the years has had a huge range of ages for software engineers. Without asking people you'd be hard pressed to know how old they were. The performance of the older engineers seemed about the same on average as their younger ones. There were some stellar and curious engineers, just as there were the disinterested ones. The same applied to both groups.

So I think saying something like "The average X year old engineer is worse than the average Y engineer" isn't useful. What's your sample size for that average?

Agree with you on the half-pay/half-hours thing. I actually would love to see less traditional reliance on 'seat time' and more flexible working conditions all around.

That is awesome! You're way ahead of a number of folks just by tracking where your money is going.

My experience was that my wife and I both worked just out of school (she at Xerox and me at Intel) where we both saved a bit and got equity sharing in our companies. After a few years (about 3 to be exact) we had enough money to squeak out a down payment on a house. (at 11% interest!) Lived in that while she went to Tandem and I went to Sun, and continued to save our pennies (our goal was to move out of the bay area, sell our house, and use the equity to make a bigger downpayment (smaller mortgage) on a house in a place where the cost of living was lower so one of us could stay home and raise the kids full time). As it turned out her Tandem stock and my Sun stock, combined with the equity in our first house allowed us to buy a larger house (with room for kids) and keep the same "size" mortgage.

It took about 10 years from the time we left school until we felt we had breathing room.
There's tons of non-virulent e. coli living in your small intestine right now... E. coli is a specific species under the Salmonella genus.

And neutral bacteria are great when they help the good bacteria out-compete any virulent strains.

I remember being told that only 1% of bacteria are virulent in bacterial phys & metabolism, NIH seems to agree[1]. And that you have 10x as many bacteria on/in your body than you have cells.

There's your answer right there.

You'll make friends while you work. You'll make friends while you travel.

Your school will certainly take you back when you're ready. You already got yourself through the door once. Just leave on good terms and they'll welcome you back with open arms.

I have severe red-green color blindness and moderate blue-yellow. As a web developer it does make me extremely reliant on the color dropper tool, and I often miss subtle color differences on pages. It's made me much more careful about how I deal with images and color in general.

I have been looking for a solution to this, I was looking a company that made lenses for the color blind: http://enchroma.com/ but it seems mostly like snake oil to me.

I will be watching this technology very carefully. I suspect it will be about five years before we hit the market though.
I use my Kindle Voayge daily. I have no issues with strain on the buttons. I did need to adjust them to the lowest pressure and highest feedback before I was happy with them.

As for full justification, I don't really mind it. It's not a pain point for me. If I wanted to be picky, I could come up with a list of minor issues.

The problem is the Kindle is the best reader out of a category of really shitty products.

I get that (in another life I'm a paramedic who responds to both numerous DUI stops, and MVAs caused by same). DUI is, however a crime, regardless of the harm caused by that instance of drunk driving.

Again, without judgment (I have little sympathy for this kid - he had repeated warnings and in-house punishments and continued to do these things, but I think a lot of computer crime is severely punished due to a failure to understand on a technical level what was going on) - is there any inclination that the prosecution believes that they're imposing "ruinous charges for inconsequential pranks" (or are they, as I said, satisfied with their approach)?

Notable features from Linux Weather Forecast by Jonathan Corbet:

- Basic support for applying patches to a running kernel, allowing the application of fixes without the need to reboot the system. There is still work to be done to get to a fully featured live-patching system, but the foundation is there in 4.0.

- The remap_file_pages() system call has been removed. Emulation of its functionality remains, though, so applications should not break.

- The kernel's support for large nonvolatile memory devices has improved considerably.

- The lazytime mount option allows for more efficient and accurate tracking of file access times.

- The kernel address sanitizer (KASan) is an important new development tool for ensuring that the kernel is not accessing memory that it shouldn't.
I've successfully learned Chinese fluently. Spending a year hanging out in a nicer part of the mainland while working through books and paying a teacher for 1-on-1 lessons a few days a week (~100CNY=$16/hr) should get you conversational. I strongly recommend considering Yunnan: good standard Mandarin, excellent weather, friendly people, good food, many points of interest. Americans can now get 10 year visas easily, though you have to exit the country every 90 days. This means you don't have to tie yourself to a formal school and its (slow, tedious) pace, plus gives you a reason to travel. Yunnan has great options for the border hops on the cheap: Myanmar and Vietnam (visa available in Kunming) and Laos (visa on arrival) are right next door, Cambodia, Sri Lanka, Bangladesh, India, Nepal, Thailand (visa on arrival) are also close.

Yes, the handbook is a complete Escher application. It simply creates a static file hierarchy while patching snippets of things together. Escher is experimental and I am iterating on other variations too. This one however is stable and complete and people are welcome to play with it.
One possibility is that cooking the food destroys compounds we can digest(like a plant's cell wall) which ends up releasing compounds otherwise inaccessible(minerals & proteins sequestered inside the plant cell).

Mastication also does this, but I doubt it is as effective as cooking unless you chew your food very well(which I would recommend doing). The downside to cooking is that high temperatures may destroy some more fragile compounds.

I guess if you are going to cook, the best way is to steam or boil/soupify your veggies. That way any released compounds are retained in solution & the heat is limited vs cooking with lipids.
Why petty? Against what/whom?

> electrical engineering is heavily dependent on rainbow color codes

I feel the need to clarify this, if only that colour blind people aren't deterred from their chosen career. There is a distinction to be made between an electrical engineer (one who designs electrical systems) and an electrician (one who installs electrical systems).

Colour blindness isn't a barrier to electrical engineering. I'm an electrical engineer and have never had a colour test in relation to my job or been queried about whether I am colour blind.

Electricians (in Australia at least) are tested for colour blindness as part of their licensing. Even there, colour deficiency isn't an absolute barrier, as the requirement is that one has to be trade capable (ie. able to do the job). It depends on the degree of deficiency, also keeping in mind that the modern wire colours for mains electricity have been chosen with colour deficiency in mind.

Colour blind and interested in being an electrical engineer? Go for it.

Colour blind and interested in being an electrician? Get advice and make sure the adviser knows what they are talking about.
