With a nickel-coated carbon nanotube or nanoporous carbon-based electrode, the thermal sensitivity and the electrode surface area are enhanced simultaneously, leading to a high output voltage around 100–160 mV and a high specific energy of 600–1800 mJ per gram of electrode material in each thermal cycle, with a mild temperature range of ~50 °C.
The problem with F/OSS in the DoD is supportability. If the software is fielded, there has to be someone (person or company) that's on stand-by that is available to support the product. This includes code maintenance and information assurance. There's a constant fair amount of personnel turn-over but the information and personnel to support the fielded software should be readily available.
In the past the GTK3 code path was tested only by Red Hat as the primary developer of all things GTK and GNOME. At that time, there was only a GTK2 build from Mozilla, and now instead of doing the same as Windows 32-bit/64-bit we're presented with just GTK3 support with the promise to obsolete the GTK2 code, while seemingly not considering the regressions of GTK3.

Why do we use Mozilla binaries of Firefox on linux distro where there's Firefox builds in the package repository? Many reasons:

1. fast access to security fixes

2. access to EMEfree builds

3. access to different channels

While it is easy to build with cairo-gtk2 as the backend, that code path, as I wrote in a sibling comment, reliably crashes for me anytime I try to do File-Open. I'll try to find out if that AUR recipe or Gentoo ebuild do something different that makes it stable, but the fact remains that GTK2 is about to be unsupported by Mozilla while GTK3 hasn't gotten stable yet, which will make life for anyone that tries to build a GTK2 variant very hard. Therefore, I wouldn't really say it's an easy choice.
Here's an example from Tyson's Corner, VA, which you might know as the home of the world's first Apple store:

Example quote (in the context of commercial shopping centers and parking minimums that apply):

> 1,000,000 square feet of gross floor area or more: Four (4) spaces per 1000 square feet of gross floor area

EDIT: Note also that you get absurd scenarios like pools requiring a space per 4 people that can use the pool, or vets having to have at least 10 spaces, and so on and so forth. Absurd regulations
You can see many tourists in Tehran and other cities of Iran. I don't think foreigners have much trouble traveling to this historical country anymore, esp. since most things (accommodation, transportation, food, and Persian souvenirs!) cost much less than they do in France, Italy, etc.

I just don't understand the reason for all this hatred toward Iran and Persians. Not saying that Persian Empires were all nice to other nations, but seriously, remember what Mongols did to the middle Asia and you can understand the difference between a well-cultured society and a vicious, barbaric one...

What did Persians do to deserve this much hatred? After all, they did not burn black people alive in Africa just like the Spanish did.

Does that mean you can use it on the virtual terminal screens? If so, that's pretty cool.

The author gets many things right, such as the change in perception of distances. I get this from VR, but I also get it from changing from glasses to contact lenses (and vice versa). Doesn't sound like complete click-bait to me.

I do think it's an interesting point that the escapism VR offers is possibly equivalent to some dissociatives, and that it hasn't really being considered. Some people struggle with addiction to (plain) video games. Blaming the person isn't fair or helpful at all.

Google Cloud's New GPU Configurations Have Deep Learning Leanings
Still relatively slow startup, even on my quite powerful computer (i7, SSD, 8GB RAM, the second start, everything already cached in RAM, no add-ons or extensions but the defaults, no sessions restored, open to empty tab) I have at least a whole second during which I don't see that the program is starting.

At least visibly better than the 49.
I'm with you and cannot stand the way Opera does it but it also has a quick tab switching mode. I haven't encountered a single switch-with-preview implementation that didn't leave me with forced slowdown and delay of the action I was about to do. I also configure Firefox to not close the window when it's the last tab, which is hard-to-impossible to emulate in Chrome but is the default in Opera and Vivaldi.
Yeah George, we're all off to the camps
I switched to google chrome (Version 54.0.2840.98 (64-bit) today and was sad when I couldn't find Noscript on chrome extensions store. But then I found uMatrix (by the author of ublock origin). I think uMatrix is almost close to Noscript security suite (no xss, abe, clickjack protection though). But I still have firefox (this latest update) running side. I wish firefox would hardcode ublock origin + noscript into its core. So users can have all the privacy and safety by default. Most people in my town don't even understand what plugins are. But I try to install these two plugins for anyone who asks me for help. I also educate them by talking about these security techniques.

I wasn't suggesting that mini-ITX was a substitute. It's only compact for something that uses standard hardware. What I was wondering was why they stuck with air cooling despite using a custom form factor. I presume there are reasons for this --- I just don't know them.

HP does claim that this machine is "63% quieter than a comparable HP business-class mini PC.": http://www.tomshardware.com/news/hp-z2-mini-g3-workstation,3.... My previous experience with HP machines though is that I hate being in the same room as one even when it is at idle. So even if this is 1/3 as loud, it may still sound like a vacuum cleaner.

I'm happy the following two are getting traffic:

Made a python command line tool that decrypts and dumps assets from an indie video game called awesomenauts.

I started knowing next to zero in assembly, reverse engineering and crypto. Took me about two months -spread accross 2 years- of work and learning to do it. The game uses a modified AES crypto, just the key expansion was modified, probably so it can be different enough to not look like AES, but still benefit from hardware acceleration. It's probably less secure than regular AES.

A very useful, tiny project I made fairly recently is Tamarind:

http://www.kylheku.com/cgit/tamarind/tree/README

Tamarind is a CGI-based web service which manages throw-away mail aliases.

You log in, and manage a list of generated aliases which instantly go into service when created, and out of service when deleted.

It runs on a Debian setup (I use Courier IMAPD + Exim MTA).

Tamarind is written in my own programming language, TXR, without any web framework: it includes all the code for processing requests from Apache, and doing session management with cookies, etc.
> Does Thorium eliminate this risk?

sigh (I hear this too often.)

No, it doesn't. Thorium in conventional, solid fuel reactors is useless. Also, conventional, solid fuel reactors are a relatively dumb idea.

We need better reactors. We have known that since around 1954. One particular design of a more efficient, safer, and likely cheaper reactor would benefit from being fuelled with Thorium. But it's about the reactor, not the Thorium!

By the way, Chernobyl and Fukushima were very different events. Different reactors, different physics, different ourcome. Don't get hung up on Thorium, learn something about reactor physics instead.
It looks beautiful to me, because all the 6502 opcodes are three letters long. Other assembly languages always looked rough and jaggy to me.
Still, there's room on the case for additional front and back ports, and all the hubs I've used have had problems. It also defeats the clean look of the machine.

Not a tool or product, but still sorta kinda. For me this year it's been making:

http://www.partfiction.com/courses/a-war-on-words/

It's not the most polished-off looking thing in the world, but it gave me an excuse to write a short fiction highlighting the importance of Black Lives Matter. It also allowed me to experiment with Greensock to put together some dodgy ass animations to go with the story. And it meant having to hear my own damn voice, urg, for some of the narration.

Also I learned a ton about BLM while making this.

Sorry if my previous message came across a bit harsh. I've been reading Chaos Monkeys lately and the author's style of writing is starting to rub off on me. I think we are indeed in agreement. As industry professionals, we do have the power to influence change. Not through wishful thinking or promises of good behavior, but by working to put in place certification/market-based systems that act as a check on bad corporate behavior. I hope we can start making progress towards those ends.
Gotta be that guy. I'm afraid "totally unique" in the app description makes me an unhappy camper. Quoting the estimable President Bartlet:

Thanks for clarifying, that's logical of course (user preferences should have priority).
I know there is no scientific evidence of a spirit or soul inside a person. But, given that most world religions teach that every person has a spirit/soul which is somehow connected to your identity/consciousness, I think it will be really interesting to see if any of these thought experiments do (or don't) actually happen experimentally.

What does it mean for religion if conscious AI emerges, or someone has half of their brain implanted into a second body, and both bodies are conscious entities that think they are the original?

What does it mean for religion if even in 1000 years conscious AI never emerges, and if it's impossible to get two halves of a brain to "wake up" in two different bodies?

Data transforms on a data pipeline without ETL hell
So I'm building a data pipeline / analytics solutions. The functionality is pretty much what one would expect. Events are received, then stored, then some transformations are performed.

We have plenty of internal users who might do transformations with code (e.g. Python) or more standard ETL methods. Problem is we end up with ETL hell when we have a bunch of these transformations we're running, don't know who created them, which ones are no longer being used, which ones do basically the same time and therefore waste computer cycles, etc. It's just a mess.

Any suggestions on best practices around the transformation/ETL stage of a data pipeline?
That's interesting. I've been happily using firefox-gtk2 and it's been working quite reliably.

Not only I haven't had any issues with it so far, it even looks better than Arch's official package (that's built with gtk3).

I find faces a little problematic actually. Since facial recognition is such a huge part of our brain, it always seems like Primitive is ignoring the face too much and spending time on extraneous details. (I've previously experimented with weighting some areas of an image more than others in the algorithm because of this.)

I think the flower works well, but I might replace it yet again if I find an even better demo when I have more time to spend on it.

> Unfortunately there's no way to buy it without the included SSDs

Ah, brings back memories of buying HP servers several years ago. The only way to get the servers we needed was to buy servers pre-shipped with inadequate RAM and drives, rip it all out, and then install new drives and new RAM (purchased at the same time from HP, for an inflated price of course). We were left with a pile of essentially useless SAS drives and ECC RAM, and still had to do all the assembly in-house.

I've never had so much trouble getting a company to accept several tens of thousands of dollars before.. or since.

That project explicitly specified HP hardware, and as far as I know we never bought HP servers again after that experience.
Yeah, I tend to agree. I think you can probably toss this on the list of lessons that human beings seem completely incapable of learning (myself included).

That escapism doesn't really work.
Thanks! That's awesome.
https://en.wikipedia.org/wiki/Identical_particles

I don't mean there is only one electron ever or something like that, just you can't actually distinguish them. There is also math which works better if Electrons have no identity.

"The fact that particles can be identical has important consequences in statistical mechanics. Calculations in statistical mechanics rely on probabilistic arguments, which are sensitive to whether or not the objects being studied are identical."

Michio Kaku – Is God a Mathematician?
One point that it looks like Curry takes aim with more generally is the degree to which there is a consensus about global warming among scientists. She says that 97% of scientists can't believe in it because they haven't studied it or built their own models, etc -- they have "second order belief"

That's an important epistemological point to make. I guess we should all make our own GCMs to confirm for ourselves that we believe in AGW?? Sure maybe if we all had unlimited time. In science we share a common set of methodological beliefs and assumptions-- maybe there's a breakdown for her there, but I'd like to think the at the research institutions and tools that exist help accurately propagate true findings to the public especially in a matter that's as pressing to our long term wellbeing as climate change!

This is cool.

I made something similar years ago. The primary motivation was my need to print small resolution images in poster sizes when camera technology hadn't gotten to the point they had high enough resolution.

Mine used transparent images as the "shapes" and then it would "stamp" the shapes onto a larger image. It could use multiple shapes in a single image.

Here's an example.

Doesn't look nearly as nice, but maybe someone with more creatively than me could create shapes that make it much more interesting. Anyone have any interest in a library that does that?

I have been using and developing inside my Vive for about a month. It's only part time, so I am spending ~10 hours a week in VR.

I certainly get some of what the author is talking about in terms of that coming-out-of-the-matrix feeling: the tetris affect of my chaperone cage is strong, and objects feel weird to interact with, using the phone UI is kinda ridiculous.. however, I certainly don't think I am experiencing any type of postpartum sadness.
