As far as I’m aware if you are talking about the Kinzhal it’s a quasi-ballistic missile not really a true hypersonic missile so it’s easy to intercept. They also claim a range of 2000km but that includes the airplane’s range.
Yes, the Kinzhal is a second stage of Iskander launched from a special Mig-31.
It is not necessarily a bad weapon but the key innovation was to save money by using the Mig as reusable first stage. Pretending it is in the same class as true hypersonic glide vehicles was just PR.
Russia is now giving up on it because it didn't work out for some reason, maybe the Migs are more expensive to operate than planned or the weapon has no element if surprise be if the special Mig starts you know the missiles are coming?
By hoodies do you mean the cotton ones with fleece linings or a lightweight breathable one? If it’s a thicker cotton one I can’t imagine wearing that in summer
As someone who has over 800 gallons in aquariums between three tanks in his house, I'll say structural support is not as important as people make it out to be (ask an actual structural enginer). Anything up to 120 or so is just fine hanging out on a floor without extra support.
Also steel is completely unnecessary unless you're doing something wild like that guy in NYC with a 17,000 gallon home aquarium. If you're just throwing a 200 gallon or so on a second floor, an enginer might not care at all if its across the joists or has a wall below it, but even if its completely open below, the "support" might just be a joist of a different design, or an inch thicker or one extra joist. Steel is really not nessecary
But big tanks do need extra support. This is a relevant thing to post in case someone is thinking about scaling it up.
The Pfizer building in NYC almost collapsed after they tried to build a swimming pool on the roof. This happens semi-regularly when building owners ignore, or don't consult, engineers about rooftop swimming pools. Every owner wants one and doesn't want to be told no.
> This happens semi-regularly when building owners ignore, or don't consult, engineers about rooftop swimming pools.
Another wild overstatement. Yeah, I'm sure the city approved this office to residential converstion with a rooftop swimming pool that has no engineering analysis. "This happens semi-regularly": Can you provide other examples? I couldn't find any with a cusory Google search.
It's just not very interesting as a whole. A quant and his programmer gf living in ny stack 3 fishtanks in a rack. It's questionable why it's even on here at all.
HU 42: TOR switch. 41-40: management server (2U). 39: git server for `fish` (1U). 38: build server for `fish` (1U). 37-28: fish (10U). 27-24: plan9s. 23-14: plants. 13-5: plumbing. 4-1: UPS.
Don't put your UPS under a fishtank, folks. It becomes an IPS when it gets wet.
You know, maybe I should reconsider having my UPS at the bottom of a rack that contains one server in the middle with liquid CPU cooling... Or just add a liquid sensor between them somewhere perhaps.
Eh, it's probably not that bad, especially if you have more stuff in between. How much liquid is in the server?
Contrary to popular belief, one drop of water on the case of an electronic rarely breaks it. You do need to get a substantial amount inside the electronic to break it.
I remember building a water sensor kit as a kid and going to the bathtub to try sensing water and my mom rushed in and stopped me because I was putting electronics near water.
Disagree - engineers documenting fun and quirky DIY projects is very much in the hacker spirit. Before reading this I didn't even know aquaponics was a thing, much less a thing with a "thriving online community".
...also, maybe I'm reading too much into this, but why not "a programmer and her quant bf"? She's the one who wrote the article on her own blog, and this is primarily a community of programmers.
