I found this confusing:

For each day of the five-week test, the system captured a full megawatt hour — enough to power more than 100 homes for a year.

This doesn't add up. I'd like to believe what they mean to say is "enough to power more than 100 homes", but the average UK home uses about 4.6 megawatt-hours per year, or 12.6 kWh per day. This is, more accurately "enough to power less than 80 homes each day".

Perhaps that's per-train, and I don't doubt that this is a significant energy (and heat) savings. But this is a surprising inaccuracy from the BBC.
Here's a fair question to ask Alan Kay: He had roles as a "fellow" at Apple and Disney and HP.

I think we all understand what the author meant by "white-man".

There has to be some term for this... The making of unneeded comments on an article that have nothing to do with the study; PC Pedantry perhaps.

At least one of the authors is a woman.
I was sufficiently good at building stuff in FPGAs and writing the software to use it that I don't need to work anymore. I see the kind of decisions that I need to make now on what projects to work on as the same as those that would need to be made by creative people receiving basic income.

People seem happy to donate to Kickstarter projects, the amounts needed would be smaller if the participants already had enough to live on.
I wrote a tiny program that captures the content of a Linux virtual console and prints it to stdout.[1] I forgot why I wrote it, but the source code shows how to access foreground color, background color and the font weight.[2] You could hack it to print everything in a format that's easily parsable, write it to a file every second and do the rendering on the client side with JavaScript.

I don't know why you are being downvoted, as you bring up a good point.

The is if not abusive then the start of a slippery slope, and you make a good argument for why that is.

It's an interesting problem: allow them to wrestle and watch it "in support" and it's borderline taking advantage. Ban them from performing a sport and its discrimination.

> If races look different, then the possibility of other metrics being different is a logical induction.

This doesn't follow. It becomes more clear why if you put it in more abstract terms. Take a bunch of balls, half red, half blue. Now assume some half of these balls are heavy (say 10lbs) and some half are light (say 2 lbs). Assume the balls have a bunch of other characteristics this way. Now what you're saying is that if we know a ball is e.g. Red, we can conclude something about the probability that it's e.g. heavy. Clearly that's not the case, why would it be? Unless you just assume a priori that the characteristics are distributed in a way that's correlated with ball color, there's no reason we should think there's an association between color and e.g. weight.
Aguri tries, which are bounded-sized radix trees with an LRU aggregation rule of joining sibling nodes.

The motivating use case is tracking metrics for IP addresses. You insert individual IP addresses into the tree, and when the tree fills, it starts rolling nodes for /32s into /31s, /30s, &c. Eventually, you get a picture of ranges of IP addresses in the data. That's neat, because, of course, IP packets themselves don't tell you anything about what subnets their IP addresses belong to.

The goofy thing I've done with them is apply them to memory addresses, so that I can collect individual pointers and bubble them up into allocation ranges, without instrumenting allocators.

Someone who knows to bring automatic differentiation into a discussion about complex-step differentiation with the implication that they have already compared them and found one wanting (while implying that they may have missed something and are receptive to contrary opinions) already knows how CSD and AD work. This person also likely know how to use google, the library / amazon, and stack exchange (at the very least) but upon running a few simple queries has determined that the approximate effort to find an answer exceeds their interest in the subject. Unless someone else can use their own greater familiarity with the subject to provide an opinion or a pointer to a specific easily accessible resource (example: lloda's pdf link, counterexample: your book link) the line of inquiry will fizzle out due to the tyranny of cost/benefit analysis and having better things to do.

I appreciate that you were trying to be helpful, which is why I'm trying to be gentle (and explanatory) as I tell you that you weren't.
Nice story. But, I'm gonna be a pooper and state people who want to kill themselves just do it. People who take multi hour walks are looking for hope, anything to use as an excuse not to kill themselves. Good this guy found his.

As an asian, I think shyness is also genetic. My parents were pretty lax in terms of discipline. So lax, that I ended up going to a community college after high school and transferring to ucla after i got my act together. This didn't stop me from being shy. Shyness is just a heightened fear response that's triggered during social situations. I think for asians the threshold for this trigger just lower when compared to other races.

That's just a misunderstanding over the definition. Racism as a subject of study in the humanities refers to these societal power structures, and it was this definition and usage she was probably cleaving to.

The world would definitely be a better if we didn't recognize labels, but since I kind of hit the trifecta as far as race, gender etc goes, I fit into society just fine. Those who feel marginalised by society for one reason or another can find solidarity and reaffirmation of their identity using these labels, and I can't really deny them that.
perhaps michael wang fell short in terms of extracurricular achievements (though this is unlikely given information provided in the article). but this is unlikely to be true of all asian candidates as a group. serious questions need to be asked about the use of subjective and hard to quantify non academic criteria that discriminate against a particular group.

the usa is after all quite unique in using non academic achievements for admissions to elite universities...
So 20 or so lines of code is too tough? How much work is involved integrating this server into an app?
This was(is?) definitely my problem.

But, after seeing how (corporate?)USA works, I was able to specifically account for it.

Here's a few things I did that might help you (list specifically geared towards individual contributors):

- made sure I was the one presenting/talking about my work (stand-ups/hackathons/etcs)

- made a list of my daily and weekly contributions that tied to big picture/visibility so I could bring those up during 1:1s. This helps a ton because I am better at "showing-off" with concrete things or in a situation that asks for it rather than just generally.

- made an effort to be a point of contact to external teams/divisions for my group/expertise.

Even now, I do tend towards "head down, work hard, hope for reward" by default. But, having a system helps me keep on track. Even now that I've got my own startup :)
Working with biosignals is a very interesting field of work

As noted, the mains hum is a major source of havoc. It is usually filtered very strongly (and you usually have to do some analog filtering, otherwise you'll get less of the original signal that you want - this also adds issues like phase distortion, etc)

You also have to use very low-noise/high-impedance input amplifiers, so either get the expensive parts or do something like this: http://www.allaboutcircuits.com/textbook/semiconductors/chpt...
There have been AOT compilers from third party JVM vendors almost since the begining. Used mostly by companies that didn't want to expose their bytecode.

However Sun decided to bet the farm on JIT and was against having AOT compilation on the reference JDK. Meaning anyone that wanted a AOT toolchain for Java had to go shopping.

Now, it appears Oracle is of a different opinion.

"Java Goes AOT" at JVM Language Summit 2015

https://www.youtube.com/watch?v=Xybzyv8qbOc&list=PLX8CzqL3Ar...

Being used to memory safe languages with AOT compilation like Turbo Pascal, Modula-2, Modula-3, Oberon, Delphi, Ada among many others, I also would have prefer that Java and .NET had offered the same type of toolchain from the beginning.

Now almost 20 years later, we need to teach young generations that their default implementations were just that, implementations. As they got used to the (wrong) idea that memory safe languages imply a VM.

Robots and Voice Recognition – what could go wrong?
> The Go server is likely faster

Which is not usually relevant if you just want to share a file over local HTTP. If you need a production-level HTTP server, you're not using either.

> it's certainly faster to type "ran" than "python -m SimpleHTTPServer".

If you're smart enough to compile ran and put it on your PATH, you're probably smart enough to create an alias for `python -m SimpleHTTPServer`.
> Isn't it wrong-headed to attempt to derive fairness out of non-fairness?

While the wording of that sounds very logical, (Isn't is stupid to try to get gold out of not-gold?), it's a pseudologic that has historically been used by the likes of Ayn Rand and other right-wing types to justify inaction. Fairness is always "derived from" unfairness. The pie wasn't divided equally? Then the fair thing to do is to unfairly take pie from the people who were rightly given their larger share. It's theirs, right? They were given it. They played by the rules, and now we want to take pie from some and give it to others? Fairness is only possible when one transcends exactly that line of reasoning.

> If the level of access to primary and secondary education is highly unequal then why not fix that first?

The most naive thing about that remark is that it's precluded by your first remark. The second most naive thing about it is that the way in which this inequality of access works, and the ways in which it can be remedied, should embarrass any speaker who asks "...why not fix that...?" Civil liberties? Just fix it. Traumatic and total devastation of an extant cultural support system by colonization? Just fix it. Centuries of ensuing racism, ethnocentrism, and bigotry reinforcing an association--in both the dominant cultural and economic systems and in the minds of the members of an outgroup--between a race or ethnicity and social unfitness and undesirability? Just fix it first.

Off topic but I hate cars that don't allow traction control (TC) to be turned off it can be dangerous.

We had Ford Transit vehicles at work and in the winter if there is a lot of snow the TC will kill 90% of engine power trapping you in the snow.

I've almost been killed by TC on a Ford Transit activating at the worst moment. When I first drove the vehicle I had the vehicle stop abruptly when the TC kicked in and a car almost ran into the back of me.

You can disable it by taking out a fuse but it also disables the ABS and airbag. Plus it was a leased company vehicle so I couldn't do that anyway.

It's like a practical joke here kill 90% of the engine power at the worst moment.

For you warm climate people drifts of snow at the end of driveways or on the road are common in winter regions. Usually you power through them if possible, wheels straight, foot down on the pedal all the way.

In the end I found out I could go fast and then put the vehicle in neutral and coast through as best I could.

I should say for ice TC is fantastic but it's not common for pure ice to be on a road, some parts but most times it would be melted by applied road salt.

That should be fixed first, but it's much more complicated. Even if you could fix all systematic issues the poor would still have less access because of poverty, discrimination, and many other forces.
It is definitely good enough to sample the signals. But why use an inaccurate title? Wiring something into a soundcard doesn't make it a microphone.
The whole energy-vs-power confusion seems problematic. This is a grid-connected system; there are no batteries. Thus it seems average power would be a more helpful measure than energy, when talking about train-brakes and households both. If one insists on discussing energy, why not quote it in joules or BTUs or whatever? One rarely sees average power used in these contexts however, so there must be something about it that the power companies don't like.

I think that's a bit literal.

No one thinks all races are equal in a genetic sense, it is obvious they are different.

They should be 'treated' equally is the thing we are taught. We all have our unique genetic advantages and disadvantages, but there shouldn't be social disadvantage based on genetics. It is good we are taught this, because it requires social change.

Also to answer your points directly, they do not at all suggest races are not equal. "Asian" isn't a race, and "Working harder" is a cultural/social quality not a genetic quality. Same with black people dominating basketball, could just as easily be explained with social qualities rather than genetic. Really you have presented weak hypothesises in the form of rhetorical questions.

Otherwise, by your same reasoning: White men people are genetically superior at leading, running companies, space travel, research, etc... Where as the truth, I suspect, lies in the context of their social situation, not their race.

in other words, use unclear and vague criteria to judge admissions that just happen to massively disadvantage asian americans. it's strange that Faust is not condemned for her absurd and racist suggestion that asian american applicants are on average much less "interesting" people.
There is PDF buried in the developers section that says that they can get 100µW with a single antenna and multiple antennas can be combined to increase the power. I think a continuously powered device would not be a good application. Instead a device that powers on occasionally where the FreeVolt is trickle charging a battery would be a better application.

I think this is a cop-out.

I've met tonnes of asians who are great at social settings. Just like I've met tonnes who aren't. Just like I've met tonnes of (black|white|hispanic|etcs) ...

I have noticed that asians engineers in particular, in a corporate setting, tend towards "work hard + wait for reward" strategy. Maybe it's the intersection of what draws us to engineering and upbringing that results in this?

But yeah, to say it's genetic is silly :)

Client side certificates – Design Issues
iOS 6 was definitely way more intuitive than its successors, though. Skeumorphism and depth helped quite a bit (think the unlock slider versus "swipe the entire screen up, for some reason, according to some hard-to-read text") and so did its commitment to keeping the home screen prominently in view when not in an actual app, sliding folders open from the screen itself and sliding it up to show the task manager rather than covering it with those same two views the way iOS7 and up do. Earlier versions of iOS had a physicality to them that worked well to increase discoverability of their interfaces.

The the "if it's not flat it makes me physically ill!" school of designers got ahold of it...
Nearly all railway vehicles use brake energy. Older trams wasted the energy with heating resistors. Newer ones feed back energy back to the grid if possible. Otherwise banks of supercaps are charged to allow going short distances without power (like old town where contact wire is not desirable).

Something like this would be especially helpful if it added live reload support. Currently I use https://www.npmjs.com/package/live-server for this, but it requires node, NPM, and including its dependencies amounts to ~1000 files. This is decidedly inconvenient in the context where I use it, which is starting out a class by talking all of the students through installing all of the above.

It would be great to have that functionality bundled into a single file executable, or rather three executables for Windows, Mac, Linux.
I read it. Unfortunately you haven't even read the definition on wikipedia. Please do.

this can be corrected for to some extent by weighting exam scores based on school/region/socioeconomic status. that would be fairer and more transparent than the current system used by elite universities in america.

I think what contributes to separation is a feeling by one party that the other one is "not responsible" with money. As with everything else, they then have to make a choice: let that affect the relationship, or not. There is also the fact that if one party earns way more than the other, then its bound to affect the relationship, especially in modern societies which believe in financial independence as a pillar of personal achievement.
There is a high barrier to research about pot and other drugs such as LSD, for obvious reason. This means that while you have a gigantic corpus of data about alcohol usage, for instance, you have next to nothing to work with on pot.

Just because you don't have studies showing pot is harmful it doesn't mean pot isn't harmful. Absence of evidence is not evidence of absence.

It is faster to use an existing tool (python or another one) than rewriting a 2K LOC one. This is great for learning Go but the compounded time "lost" with a "slow" python server is nothing compared to the time this tool will require in development, debugging and maintenance over the years.
