Just saw this, searched for the project, and found this thread.

A similar thing has happened to me in the past. Brought a phone dock from amazon, and when it arrived, it didn't fit my phone, looking at the serial number on the dock itself, it was for the previous model of phone but the packaging was for the latest.

So someone had decided to upgrade for free.

https://news.ycombinator.com/item?id=23852177 explains it, with a quote from the article. They weren't able to map the whole thing, because of repeating patterns. That's now starting to change.

Well, as he says in his video, it's typically the queen that dictates how aggressive the colony is.

Watching the video, he taped the hive up and then poured the soapy water in. I doubt that many were able to get away at all.

Those that were out foraging, would probably die pretty quickly without a hive to go back to.

Some hives have enclosed floors. But modern hives, at least in the UK, now have a mesh floor. Which is there to reduce the numbers of a parasite, varroa. The mesh allows the parasite to fall out of the hive.

That's an interesting question. I'm not sure how you would pump CO2 into a bag and kill a colony. I'm not sure it's an accepted process for doing that. Maybe there's a chance you might accidentally euthanise yourself.

I imagine at the start of the process, he was hoping to just kill the queen, and the entire colony would survive. In that case the other bees would replace the queen, with an emergency queen cell, if this was to happen the queen would probably be as aggressive as the previous generation.

But he mentions that he intends on introducing a queen himself. In which case, I would have thought the colony would calm down.

But I have no idea how much by, because I've never been in this situation.

Well the video at 3 minutes in, with the Bees flying all over the camera and attempting to sting him. You can see them flying towards the chap, and you can tell when they're doing that that, there's some intent that they want to sting you. I've noticed that they like to go for the face. Probably something to do with the chaps breath.

I went on a year long bee keeping course and I've had my hives just for this season. The hives that I have...I thought were much more aggressive than the hive I looked after on my course, But they're no where near as aggressive as those bees. I had a short period of them being more aggressive, and I think that was due to them taking nectar from oil seed rape (A variety of canola) or the sugared water that I was giving them. They've much calmed down now.

Compared with when the guy is meters away from the problem hive, with mine when I've cracked the hive open, doing an inspection, and I'm accidentally squishing them all over the place. I have a few trying to sting me, but not in the numbers that he's seeing.

I'm actually working about 10 meters away from my hive, in my garden now, and I'm not seeing any bees at all.

The only bit of wisdom that I could add to this discussion is that, on my course, I was told that the more genetic variation the bees have the more aggressive they are. If you import a queen from Italy, from an Italian variety, for the first year they'll be calm, but when you get subsequent generations of queens from that Italian queen they get more aggressive. I guess hybrid vigour makes them aggressive. I suppose especially so with hybrid varieties from Africa (Africanised), but I've not heard much about them in my local area.

That's funny, I just saw this suggested to me too, but I'm a beekeeper, so I wasn't expecting this to appear here.

It appears, halfway through reading this, it's become password protected.

Yes, I thought so too. But wondered if it might have been a comment about the general state of the Internet instead.

Ah, this is a really useful topic, following on from the previous post about DIY weatherstations. I'm currently adding my data to wunderground, but I'm not getting a huge amount of value out of it.

Really happy to see other options.

Yeah, it's useful if you want a static website for your weatherstation. But I would quite like the current readings, to actually be current, rather than up to 5 mins old.

Yes, they do fail. I guess that's evident by the design of the weather station, as the humidity sensor is modular, so it can be replaced.

Unfortunately, I think this design also means it has a low ingress protection value. The unit I ended up with had the humidity sensor replaced and it still wasn't providing numbers. I think it may have spent a year or so out at sea on a buoy.

I'm using weewx for my weather station. I pulled the weather station out of a bin at my former place of employment, which is an airmar 200wx, ultrasonic wind sensor that's typically used on boats. The humidity sensor doesn't work, so I wrote a python script, that acts as man in the middle, that reads in the data, and when it gets to the humidity values, it replaces them with numbers from a DHT22 humidity sensor instead.

If this was posted on the 1st of April, I wouldn't believe it...

Yeah, I'm not particularly keen on the BCS either.

Perhaps the ycombinator equivalent to being slash dotted has occurred.

Here's a copy https://web.archive.org/web/20181013192728/http://scoraigwin...

Yes, I've purchased the designs to one of his turbines.

I don't think off grid, means completely isolated from the rest of the world.

That article includes a comment from resident Hugh Piggott, somewhat of a rockstar in the DIY wind turbine world.

Huh, I never thought about Switzerland being a third world country.

Yeah, it's working for me, since about Wednesday/Thursday.

No but they did attempt to ban neonicotinoids across Europe, against stiff opposition from the UK government.

OK so this started to change my opinion of Google. I could see how, in the article the marketers were trying to describe the map-reduce algorithm and how the journalist could have mis-interpreted it.

But this is categorically bad behaviour.

I noticed that too, I like haskell, but I don't believe it.

"A few hours later, Clarke was looking at a blueprint for an 8,000-pound machine that used hydraulics and electricity to focus increasing amounts of pressure and heat on the core of a sphere. The device, he was told, re-created the conditions 100 miles below Earth's surface, where diamonds form. Put a sliver of a diamond in the core, inject some carbon, and voil�, a larger diamond will grow around the sliver."

"Password Safe" isn't a traditional password manager?

REST API? Wind turbine SCADA systems use interfaces like modbus or canbus, etc.

Security in these systems are dedicated network circuits and firewalls configured to only allow access on a specific port, from a specific IP address on a specific port.

"1 packet from Russia"? This requires physical access to 1 wind turbine in a networked Wind farm, which is going to be at most 250 turbines and I'd be really impressed if they were all networked together.

"Full speed reverse?" You could perhaps increase fatigue overtime. Some wind turbines can start spinning to get to a more favorable position in their power curve, I'm not aware of utility grade ones being able to do that, or go "full speed" enough to cause physical damage.

I have some experience with network access in a UK wind farm. They were extremely paranoid about network security.

So the significance here is that if you had remote access to a single wind turbine, you can control the others? Implying, if there were a vulnerability in the control system of one turbine, the rest of them are exposed? Rather than showing that you can stop wind turbines from spinning, if you had physical access to the turbines.

Their "hack", which requires physical access, is about as practical as throwing a physical spanner in the mechanics.

EDIT: I'd like to point out, there are reasons why you might want to be able to access the SCADA system of other wind turbines, from the network access of one wind turbine, which would be to allow wind-yaw optimising wind lidar systems to optimise the yaw of other, local, turbines.
