* Sand is not a good substrate for plants. Too fine - aeration problems; surface to volume ratio not good. Anaerobic zones will form. Denitrification with odor will stress plants and fishes.

* No dedicated biofilter. Nitrification bacteria will form and live on the sand. Tight coupling between fsh tank and grow beds. No way to decouple when one or the other has to be maintained.

* Fine mesh preventing the sand to get into the fish tank will clogg with detritus.

* Grow beds will clogg with detritus after approximately one season.

* No sump tank. Water level in the fish tank will vary a lot. Fish don't like that. Stocking density will have to be low to aleviate this.

* Too much sun on the fish tank. Most fish species don't like this and algae will form rapidly.

You should try InWorldz. It doesn't use a HMD yet (though there has been some work done on a true VR client), and the graphics quality and physics may or may not be as perfect as you want, but it fits what you are looking for exactly in the social aspects. There is no 'game' per se, other than whatever contests, roleplay etc. that users might choose. Some people do spend most of their waking hours socializing there, or running real businesses there, etc. All the content is created by users.

Calling this an HSM is somewhat disingenuous, as it seems to contain none of the usual defenses found in a "real" hardware security module, like tamper self-destruction of key material, and likely no side-channel protection.

This is essentially just putting your keys on a dedicated computer, connected over USB. That does have value, mind you. Keeping your keys isolated definitely makes it harder for malware to exfiltrate them, and a "trusted UI" makes it clearer to the end user what's happening.

I was born and raised in Brooklyn, NY, but moved out to rural NJ in my thirties. I bought a house on a lake with no motorboats, plenty of black bears and raccoons and lots of trees. I now live in the rice fields of East Java, Indonesia, so I guess you can say I love the outdoors.

I do question the science or numbers in the study as much as I believe the basic premise to be true, however, correlation does not automatically imply cause. People suffering more after trees are removed can also mean that urbanization or development brought factories, or unhealthier air, rodents or any number of other negative factors with it.

I do intuitively relax more, and take great solace in my surroundings, and I do believe it is better for people. I would like to see more research on this; there have been a lot of debacles in the past two years in the social sciences and psychology with statistics and peer review. Some of the studies were taken for granted and are now under the microscope for being inconclusive or just wrong.

It is very common to suggest to people new to the game of go to lose the first 100 games as quickly as possible [1]. Not "play", "lose". The fact is you will lose a vast majority of the first 100 games you play because the initial learning curve is so steep. It's hard to even imagine what moves might be reasonable when you start playing. So the idea is to not focus on trying to win or thinking through what your best moves might be, but to just get accustomed to some basic patterns, common positions, etc first. You have to build up a certain body of knowledge before you can really think about what moves you might want to play. So just play a lot of quick games and accept that you will lose and come out better on the other side.

Replying to this comment here since it got nuked in the other HN thread.

> I think BLM is about ENDING violence. I worry that their is a small minority group within them that are starting to advocate for it, or at the very least not speak out against it (violence and harassment of police).

Right ... that's what we should be worried about here, trigger happy BLM advocates. The cops are a bigger issue and the Black Live's Matter movement is serving a purpose calling to attention these unjustifiable murders.

In the late 60s, J Edgar Hoover tried to eradicate the Black Power movement with COINTELPRO but ended up doing more dirt and using more shady tactics than the Black Power movement could have ever been capable of. The Black Power movement was initially a non-violent political party under the aegis of Stokely Carmichael in the south. It did not acquire its "criminal" (I put that quotes) element up until the party found its way into Oakland, and by then Carmichael had washed his hands clean of the party (he was actually deported from the US and had to go live in Ghana). Basically, like BLM now, it was way too fragmented a movement to have posed a real threat to society at large. So the suppression tactics used by the FBI were massively overkill and unjustifiable given the context.

So if there's anything we should be talking about right now it should be Alton Sterling and Philando Castile's murders. Cops can take care of themselves - young black males ... ? Not so much.
The usual term is strong versus weak memory models. In x86 and SPARC (TSO), the only reordering in hardware that you can do is having reads complete before pending writes--all writes happen in order, all reads happen in order, and a pending read must complete before a pending write can. Other architectures allow much more reordering at the hardware level.

If you know the C++11 memory model, x86 and SPARC (TSO) basically make all memory loads implicitly atomic release/acquire. In contrast, most machines follow something akin to release/consume (the DEC Alpha famously has a basically broken memory model that allows *p to complete before p).

> Calling this an HSM is somewhat disingenuous

Well, I had to call it something. I'm open to suggestions.

> tamper self-destruction of key material

That's true, but there is readout protection built into the SoC.

> and likely no side-channel protection

Side-channel protection is provided by the software, which is a side-channel-resistant implementation.

But the principal attack model is a compromised client machine, not physical compromise of the device. There's only so much you can offer for <$100.
I've been watching this project since I saw it mentioned in an HN comment some time ago, it's nice to see stuff like this being worked on. Doubly so because I envisioned building something similar a few years ago using the Beaglebone Black as the platform, but this is much better all around :)
I think the manually minified version was done for fun. A lot of programmers like to play this game. For me, the tiny version is fun to see, but not to read, so I'm glad he made the regular version available as well.

Actually, I first heard about this guy through this vimeo video:

https://vimeo.com/169747974

It seems to paint a similar picture to the NY Times article, and appears to be a fair summary of him. The firearms are a part of his life, and I don't see the NY Times article making a big deal of it. The reporter perhaps just isn't used to someone carrying around assault weapons, so is naturally a little bit freaked out.

Overall, both the article and video are a fascinating glimpse into the life of a fascinating man who has very successfully created his own destiny.

At least in my mind, the defining attribute of an HSM is protection against physical compromise of the device.

Maybe we disagree on that definition: I guess it is hardware, and it exists for security, and it's a module.

I admit it's unfair to compare this with a $10,000 HSM from Thales or Safenet, of course. But it seems like a smartcard based solution might be better on that front, as they're designed to withstand physical attacks.

You can defend against some side channels (timing from the host, for example) but I was thinking more like EM/RF emissions.

I want to be clear that I think this is still a great project, and I commend your work so far!
Yep. There's lots of scary warnings when buying even mini fridges that you can't operate it for at least 24 hours if the unit was rested on its side during transport to you.
It seems to me that the situation is very fragile and worrisome, mainly for 2 reasons. China once (1958-1962) had a Four Pests Campaign (除四害运动), which defined four pests to be eliminated: rats, flies, mosquitoes, and sparrows. In less than 1 year, nearly 2 billion sparrows were systematically exterminated. I'm not saying that North Korea will do the same thing, but a starving country with a totalitarianism government is one of the worst threats to nature, as China has clearly shown. On the other hand, should the political situation change in North Korea (in any direction), nature will as well be the first to suffer, as China has clearly shown.

This seems rather childish of the reporter. There are armed guards in the Charles de Gaulle airport with assault rifles and these guns are available and visible in common stores in most places around the US.

It's as sad as a reporter writing how afraid they were of being bombed at every air show they reported on.

While statically linking most certainly has its use-cases (as the parent comment pointed out), it unjustifiably presents challenges that would not otherwise occur.

To elaborate on the parent's example: a particularly bad bug in a library depended on by a set of programs might not cause much of problem if you build and deploy this software yourself.

However, it would be a more significant endeavor on both the distribution's part (recompile, repackage, sign-off, and release every program in the set), and on the user's part who has to download the large binaries each time a dependency is updated rather than a small library. This problem is further exacerbated by the npm-like dependency graphs rust programs tend to end up with. Take servo as an extreme example of what these graphs might look like: https://web.archive.org/web/20160703132700/https://dirkjan.o...

Furthermore, I don't see how dynamic linking prevents the compiler from optimizing the resulting binaries. C libraries have been dynamically linked for decades without issue.
I'm generally supportive of increased gun regulation but that wasn't even on my mind while reading this article. I just read it as an interesting look into the life of a guy living in solitude. I didn't really care what he was doing with his guns.
BSD development versus Linux development is not an example of the Cathedral and the Bazaar. That essay was about development process: under the Cathedral process, development happened "behind closed doors" and the only time the public got access to source code was at release time; under the Bazaar process, development happened "in the open" and the in-development source tree was always available to the public (typically via a source control system).

To see why the various BSDs are not an example of the Cathedral process, you only need to look at their source control. In fact, OpenBSD pioneered the idea of anonymous CVS -- before that, you needed an account to check out from the CVS repository:

"When OpenBSD was created, de Raadt decided that the source should be easily available for anyone to read at any time, so, with the assistance of Chuck Cranor, he set up the first public, anonymous CVS server. At the time, the tradition was for only a small team of developers to have access to a project's source repository. Cranor and de Raadt concluded that this practice "runs counter to the open source philosophy" and is inconvenient to contributors. De Raadt's decision allowed "users to take a more active role", and signaled the project's belief in open and public access to source code." [1]

Consider a country with utterly uniform population density. It is trivially false that you can draw "a straight line with 6% of the population on the larger half, and 94% of the population on the smaller half" in such a country. I would be very surprised if all countries in the world were far enough from "uniform population density" for your statement to apply to them.

I'm hardly a beekeeping expert, but I've read that human managed colonies are actually not in decline.

"The 2014 numbers, which came out earlier this year, show that the number of managed colonies -- that is, commercial honey-producing bee colonies managed by human beekeepers -- is now the highest it's been in 20 years." https://www.washingtonpost.com/news/wonk/wp/2015/07/23/call-...

The article argues that CCD has made beekeeping more expensive, which is a cost passed onto consumers in the form of more expensive honey, but beekeepers have found ways to keep their colonies from disappearing.
