jmhobbs··on I made a chair
I built some Leopold benches a few years ago, great bench and nearly as simple to build as this chair. Maybe simpler as there is no cutouts or narrowing like OP.

jmhobbs··on Show HN: Scooter – Interactive find and replace in the terminal
Very cool! I currently use `sad` for this, if you're already an fzf user you should check it out.

jmhobbs··on Ask HN: What's the most creative 'useless' program you've ever written?
I wrote a script to monitor the process monitor God [1]. which I called Margaret [2], playing off the famous Judy Blume book, "Are You There God? It's Me, Margaret". [3]. Silly, but I enjoyed the low effort joke.

jmhobbs··on Ask HN: Concise, pragmatic baby manual for first-time dad?
As a father of three, all of these things are great.

Keeping a change of clothes and a couple diapers in the car is another thing to recommend, you will eventually forget the diaper bag, or forget to reload it. Having last ditch emergency supplies is a lifesaver.

I'd add a NoseFrida as another product, those bulb type snot suckers have poor control, and get disgusting on the inside. It's a bit weird the first time, but it works a treat.

jmhobbs··on Honey consumption improves blood sugar and cholesterol levels, study suggests
The domestic honey bee is honestly doing fine these days, varroa is better understood and controlled (for now) in captive populations.
jmhobbs··on Honey consumption improves blood sugar and cholesterol levels, study suggests
The argument is that non-native honey bees (if you live in the US) put pressure on the native pollinators competing for the same food sources. It makes sense logically, since commercial producers will have huge bee yards and do migratory beekeeping to follow the pollination contracts and the honey flows. I have not, however, ever seen a study on it. I've also never really gone looking.
jmhobbs··on Honey consumption improves blood sugar and cholesterol levels, study suggests
Even among 100% real honey, the ratios of sucrose, glucose and fructose vary wildly. At the extremes tupelo honey is very high fructose, and thus is famous for not crystallizing easily. On the other hand, canola/rapeseed swings so far the other way that it can crystalize in the comb before harvesting.
jmhobbs··on Compostable fungi-based replacement for styrofoam
Does it if you're not fruiting them though? I make 5lb hardwood sawdust bags with about a quart, quart and a half of water, and that's all that is needed for the mycelium to colonize the whole thing. I suppose at scale a liter for a 12"x6"x6" block is perhaps a bit much lot.
jmhobbs··on Solar-powered robotic beekeeping
I'd be surprised to find any commercial keepers using polystyrene. Migratory bee keeping is rough on equipment, and at scale I think woodenware still makes the most sense. I'm not in that community, but everything I see in Bee Culture and online looks like polystyrene is firmly in the hobbyist realm.
jmhobbs··on Solar-powered robotic beekeeping
That sounded dodgy to me but it does look like it's got some legitimacy: https://scientificbeekeeping.com/a-test-of-thermal-treatment...

I mostly use oxalic acid, but if heat treating becomes viable I'd welcome it on the hobbyist scale.

jmhobbs··on Solar-powered robotic beekeeping
Honey bees are the easiest to manage really. Some other bees are raised for pollination, but honey bees have a long history of management and semi-domestication. We already know how to raise and manage big colonies for migratory pollination.
jmhobbs··on A terminal multiplexer with full gesture support built on WebRTC
I don't have any useful opinion here, but the demo video uses my terminal-parrot[0], so it's clearly a great tool.

edit: On closer inspection of the video at 1080p it actually uses parrot.live[1], so it's an OK tool ;)

jmhobbs··on What is a resilient chicken?
I ran cornish cross meat birds twice, 20 birds each time, and by butchering at ~8 weeks the roos didn't get around real well anymore, given the weight to leg ratio.

Those were pasture raised, with restricted supplemental feed, and just the ordinary breeds you can get at Tractor Supply. I wouldn't be shocked if you let a "real" production hybrid go past butchering age and feed them grains the whole time, you'd probably get some birds unable to move under their own weight.

After two rounds, I gave up on them and now run less aggressive weight gainers that forage better, like freedom rangers.

Obviously just anecdotal, but don't dismiss it outright.

jmhobbs··on Linux VS open source UNIX
edit I missed the "custom" part of your comment. I don't remember that ever being a thing, but I never got particularly detailed with moving the levers around before.

It's in a collapsed section titled "Choose where your money goes" which is beneath the price selection tools now.

jmhobbs··on Ask HN: What do you do with your Raspberry Pi?
I used mine to build an egg incubator this year, http://www.velvetcache.org/2018/03/04/chicken-cam-incubator-...
jmhobbs··on Most 'meat' in 2040 will not come from dead animals
While a laudable environmental goal, I just don't see that much industrial farming shut down in just 20 years.
jmhobbs··on Coolest Things I Learned in 2018
Honestly, I'm not even sure. After watching the nvidia youtube video, I retract the statement. This is pretty amazing.
jmhobbs··on Coolest Things I Learned in 2018
I'd love to see a source on that one, it's hard to believe otherwise.

edit: I reverse image searched one of the faces and found this, https://bgr.com/2018/12/18/nvidia-ai-fake-faces-look-100-per...

It's not generating them from whole cloth, but it's still very impressive.

jmhobbs··on Ask HN: What's your catch-all note taker?
I tend to capture stuff in Quiver[0] now. It has decent search, shared notebooks, etc.

jmhobbs··on Making Pulled Pork with React Native, Expo, and Express
Open source Go one called QPID on the Raspberry Pi, https://github.com/bbqgophers/qpid

Fairly easy to glue together sensors to roll your own, I made an egg incubator with basically the same pieces that had a webcam too, http://www.velvetcache.org/2018/03/04/chicken-cam-incubator-...

I like the reuse of the phone though, I wonder if there is some sort of bluetooth board out there that can bridge the phone to the gpio stuff.

Nice! Packr is pretty good too, what I currently use.

jmhobbs··on SpaceX craft overshot Mars’ orbit and is headed to asteroid belt
Wikipedia says 140k to LEO, 37k to Mars and 7k to Pluto. Still, there's excess capacity there if a roadster is about 3k. Does seem like they sent it as far out as they could with that payload.
jmhobbs··on Travel the path of the solar eclipse
Not a journalism piece, but this is a great map for getting details along the path;

jmhobbs··on Japan Pictures Likely Show Melted Fukushima Fuel for First Time
Underground coal fires like the Centralia mine fire are an interesting and not as well known problem as oil spills.

> The fire is burning in underground coal mines at depths of up to 300 feet (90 m) over an 8-mile (13 km) stretch of 3,700 acres (15 km2). At its current rate, it could continue to burn for over 250 years.[2]

jmhobbs··on Dead Man's Switch
Great idea!

I'd like to see an answer to "How will you ensure the continued operation of this service over N years?" on the help page though.

jmhobbs··on Starbucks Prospers by Keeping Pace with the Coffee Snobs
I started as simple as a pan on the stove and a spoon. It's better if you can do it outside or somewhere well ventilated, burning chaff isn't the most pleasant smell.

If you can make friends with a local small batch roaster you can pick up a lot of info quickly. The ones I've met love to talk shop about roasting. And they can sell you some of their stock directly, so you can try more things without waiting for it to get shipped to you.

jmhobbs··on A Field Guide to the Hidden World of Digital Networks
This is a neat project where they make a very one dimensional rendering of actual WiFi signals.

Not quite the same, but the only real world instance that came to mind.
