We have e. coli as part of our gut biome right? Curious how dangerous, if at all, it would be to get this modified version in there. I have a hard time beliving it is very efficent so doubt it would somehow electrocute you from the inside, but could cause other issues.

I wonder how it compares to something like methane digesters in production and ease to maintain. Seems like it would produce less energy and not make nearly as good fertilizer, but be much less finicky and not require an anaerobic environment or careful temperature control.

domtron_vox | 2 years ago | on: Lemmy now has over 2M users across 915 instances

Haven't used lemmy in particular. But in theory defederation exists to block bad actors. Since anyone can host a server themselves and no one can stop the servers outside some kind of government intervention, each server needs the ability to block a spammy or even illegal content filled server.

In reality, it is used for that and the censorship of ideas server owners don't like... or even just blocking a server because the admins of each server had a spat. It has been likened to little fifedoms each with their own flavor of tyrant, a little drematic imo but not wholely wrong either.

Another use is if you want to use the software, but don't want/need connections to the greater network. So you fully defederate and only allow your friends to have logins to your isolated server.

We usually asked with only a few turning us down, though we are fairly rural/small town so the builders we interacted with may not have been burned by people that are sue happy or maybe are just smaller and didn't consider that legal aspect.

Good point. Never ran into anything problematic myself, but we are fairly rural so construction is usually houses with occasional apartments. But definitely be wary of other stuff that may be in with the wood.

As for pressure treated wood, it is pretty obvious what has been treated and what has not, at least in my experience. Not sure if it's the process, or if they intentionally dye it, but treated wood has a strong green tint, though could probably have other colors too depending on the treatment method. But fresh untreated pine has a pretty obvious color.

My family always hit the construction dumpsters. You can get a lot of decent pine lumber that gets tossed because it was cut wrong or stained with mud/ptty/etc. They throw a lot out because time is mor valuable to them then the wood. Even short end peices are useful for burning or turning into charcoal. Pretty rare that you get decent lengths for building though. Usually 6 feet and below are fairly common, with the rare 7-10 foot boards, and nigh unheard of 11+. And the builders are usually happy about it too, since they pay to have it emptied so everything you take is a bit less they have to pay, and no skin off their nose.

We have built a number of animal houses and even a few sheds around our land with the salvaged wood. Saved us a lot of money.

Grow plants > feed to goats > collect menure > anerobic decay (aka methane digester) > natural gas (pretty close anyway) + good fertilizer.

That's the system I'm interested in. The only real issue is needing to filter out a sulfer based gas (forgetting the exact thing off the top of my head, but it's corrosive to metal)

domtron_vox | 3 years ago | on: Ask HN: Favourite open source game?

Haven't seen these two so thought I'd add them to the list.

Minetest is a block building game engine (like minecraft) built around the idea mods add all content. There are a bunch of games built for it, and last I checked a active modding community. https://www.minetest.net/

The other is AlephOne, a engine to play all the Marathon games (story FPS, pre-halo bungie made games) along with a bunch more community created ones. I've sunk a good bit of time into both the trilogy and the additional 6 big community made ones. https://alephone.lhowon.org/

domtron_vox | 7 years ago | on: Ask HN: How to encourage and maintain a long term organizational knowledge base?

Ironically I'm rolling out a new documentation initiative at my workplace this friday after about a year of work.

I'm using mediawiki with quite a few extentions to meet our needs.

I designed the structure around use cases since the documentation is for me and my coworkers to make us more effective. I'm also making it clear that if they have any issues or frustrations to contact me and I'll try to fix them quickly. I.e. lower the bar as much as possible to get people to use it.

As a general rule if someone is asked a question (internally) more then twice it should be documented to help save them time.

For our structure we use a heavily formatted main page with the 1st half focused on handeling emergancies, req/report forms, and general quick links. The 2nd half categorises all pages into 3 functional groupings. Guides to handle step by step process pages, notebooks for longer explanations for training etc, and referance for lists/tables of data.

These are then further divided into department focused groups.

Tl;dr IMHO do a bottom up design based on use cases like emergancies, quick lookup, normal day to day tasks, edge cases, etc.

In my experience, Xbox controllers are actually fairly common for large robotics. It is relatively cheap to buy a controller and USB wireless dongle plus there are lots of software libraries to help interpret controller input.

My main experience being my participation two years in a row in the Intelligent Ground Vehicle Competition (IGVC). A college competition to develop self-driving rovers and "cars" (golf carts). There were around 40 teams from various colleges (several international, not just usa) and many of the teams used xbox controllers for manual control including my team.

domtron_vox | 8 years ago | on: Ask HN: Where have you registered your domains and why?

Same, I have two personal domains with them and the free Whois guard sold it for me.

We use namecheap at work. Recently they have been messing up dns (I think it was a one time thing). Not a huge amount only like 3-6 domains out of 400ish, but it's silent. We caught most with monitoring, but have found several that slipped through the cracks since.

domtron_vox | 8 years ago | on: A CMS with no server and 18 lines of configuration

I would have to agree with Operyl. I don't have a reason to use the CMS in a desktop app and the site will be pretty low traffic, probably 20-30 unique visits a year or less, and all of it local so I doubt cloudflare would be needed. And I would netlify would have something similar protecting their servers.

That said, it would probably not be that hard to create that electron app. You just need to include 3 files to get netlifycms to work.

domtron_vox | 8 years ago | on: A CMS with no server and 18 lines of configuration

Just adding my 2 cents.

I'm creating a website for my parent's farm. Right now I'm using netlify for hosting(free), metal smith as generation, and netlifycms so my parents can edit the content.

For example we raise registered goats so we need to add info for each goat to the web site. I added a new collection for goats, configured it to have the right fields, and added the needed layouts to metalsmith. The information is then used in creating both a summary page that lists all the goats and individual pages for each goat. Only thing I have to pay for is the domain.

I'm really liking it so far. It seems to be very flexible with the ability to extend the code and write your own widgets.

My only complaint about the CMS is the documentation is lacking so you have to dig through code to fix some issues.

Thanks for making this netlifycms devs. :)

domtron_vox | 9 years ago | on: Autonomous Robot Surgeon Bests Humans

> a bot stitched up a pig’s small intestines using its own vision, tools, and intelligence to carry out the procedure. What’s more, the Smart Tissue Autonomous Robot (STAR) did a better job on the operation than human surgeons...

I'm curious if they took into account how a person will do a better job when said job is important/risky to themselves. I. E. stitching up a human where a mistake has dire repercussions vs stiching up a bit of desposable flesh.

Was the pig even alive?

domtron_vox | 10 years ago | on: Incoming space junk a scientific opportunity

> "The object is only 1 to 2 metres in size, and its trajectory shows that it has a low density, and is perhaps hollow. That suggests an artificial object, “a lost piece of space history that’s come back to haunt us”, says Jonathan McDowell, an astrophysicist at the Harvard–Smithsonian Center for Astrophysics in Cambridge, Massachusetts. It could be a spent rocket stage or panelling shed by a recent Moon mission. It is also possible that the debris dates back decades, perhaps even to the Apollo era."

Probebly.
