I think it depends on the context - if you're designing the whole system from bar code to camera, I'm not sure that the color will help. But in that case you can assume close to perfect optics and I'm not sure if you would fi

Cameras only see one colour per pixel (i.e. Bayer colour filter array). Because our eyes are not so acute at resolving colour compared to luminescence this tradeoff works well. But in this context I'm not sure at a pixel level how much

There is a real, if small, chance that there could be a general election in the UK soon and potentially a more favourable labour government. If I were Assange I would do whatever I could to hang in there at least long enough to rule that po

Yup it did - I was flying aerial surveying at the time. Bad timing. Actually I didn't notice anything in the end so was all good but when I saw the NOTAM I couldn't believe my bad luck. Edit - link: https://www.theregis

No I don't, my calculations at this stage are as follows: Sail area - same as my 10 ton boat. Gets me to 7kts in a good strong wind. Boat they intend to install it on: 110000 tons! My point is that for this to have any impact at all, a

I understand that, in fact probably uniquely to people on this thread I've been on a rotor sail boat (not sailing though, in dock). They do work when the ratio of the sail area to the boat is appropriate. In the case of the one I went

My back of the napkin assumed all energy from the wind over the entire cross sectional area. Magnus effect or not, i'm just dealing in orders of magnitude and for the average wind speeds on shipping routes, I just don't understand

by qume 8y ago
I really want this to be a thing, but my rough calculations given the total cross section area of the sail and the average wind conditions on shipping routes come out to as close to nil as makes any difference for ships these size. I posted

I build camera gear for 172s and fly (as passenger, not pilot) probably 20-30 days per year, sometimes much more, and I get nervous at <60kts at low altitude. 40kts IAS is I guess around the full flaps stall speed but you sure don't

Very thought provoking. I'd like to add that this could be the case 'subconsciously' without him realizing or rationalizing it to himself.

My small 12 meter long boat has a sail area of 900sqft. When sailing perpendicular to the wind it captures pretty much all of that. The sail on that ship is 100' high, and looking at the aspect is around 15' wide, or 1500sqft. Tha

Wow that was downvoted. I guess these people aren't aware of Nimoys extensive practical jokes with Shatner. But even so, why would anyone downvote this?

Yea flight avionics, sort of. Aerial camera systems and the UI to control them.

Wow this covers a lot of my job, and is really concise and well written. This might be the best link ever posted to HN for me. Thank you.

Hey respected downvoters - pure means homogeneous. Can you please explain to be what ultra homogeneous means? When discussing scientific concepts being haphazard with language seems like it should be called out, especially when the source i

I used MacOS for years and loved it. But now have been on linux (on both Mac and a X220) exclusively for a few years and I'm honestly confused as to why a developer in this community would even think of not running Linux full time. I h

I cant stress this enough: flights are a great opportunity for mental down time. The only mental down time I ever seems to get at least. Savour it. Value it.

We are interested in going down this path, would love to hear from anyone using it. Also we need to deploy portable versions of the whole server side offline. Ie in docker or a VM or just on a linux box.

After all these years I was just about to try using macrofab and getting electronics produced in the US for the first time. I guess that doesn't make sense now. I thought this was all about encouraging US manufacturing jobs?

Light travels around a foot in a nanosecond. Makes thinking about processing times a bit easier when you can visualise it as a distance.

Massive difference between vegetarian and whole food plant based. I hear what you're saying, but I didn't mention the word easy, just that everyone I know who has switched to a whole food plant based diet has lost weight, whether
