    I was gonna write a thing about how you were wrong, but no you are correct. A lot of cameras are actually counting pixels by the number of photosites they have behind a beyer screen...
     
    I guess the only exception to that is 3CCD cameras, but they are increasingly uncommon these days...
     
    That is super bs marketing though, I'm surprised more people aren't aware of it! Even on the green channel, that's half the effective resolution!

    I'm in Canada and I do not expect to get vaccinated until September or the first half of October. Vaccine is more likely before GPU, but there is a realistic chance, however small, of snagging a card on a restock. There is no "notify me" option for a vaccine!

    Next month? You are an optimist, aren't you?

    I expect the best that vast majority of us can hope for is 4th quarter of 2021 -- and more likely? A year from now.

    Joshlikescola got a reaction from kelvinhall05 in Why the Perseverance Rover computer is so "outdated"   
    It's an interesting question - one I wondered myself when I found out the specs of the system! 
     
    I think there is often a large gulf between consumer and professional grade hardware in many industries. Often industry appears to be using seemingly outdated or antiquated equipment - but there can be good reasons behind it. 
     
    Other examples that spring to mind is the US nuclear arsenal running off 70's era floppy disks, and the automated Vancouver Skytrain also requiring newer 80's era floppies to boot. 
     
    I think its likely there is some more familiar consumer-like microprocessors on board, for doing some interesting machine-learning type stuff, but these are certainly not in control of the rover. 
     
    I think it really comes down to KISS (Keep It Simple Stupid!) 
     
    I'm often happy to champion the simpler solution, with less complexity to go wrong and more resiliency. I certainly wouldn't trust a windows computer to land a $2.4bn rover on the surface of Mars! 
     
    Interestingly, I believe ethernet and USB have been deployed to connect some of the cameras up. The link between the rover and sky crane was an ethernet cable. 
     
    As other people have mentioned, the rover only really needs to carry out data collection, a lot of the heavy processing can be done on earth. I'm sure in that case a lot of powerful hardware will be deployed! 
     
    I don't think people should jump down OP's throat, they put "outdated" in quotation marks and clearly created the thread in the knowledge that there was probably a good reason for it. It's a really interesting subject looking at the deployment of computer systems in various industries, and how some surprisingly basic hardware, perhaps long forgotten in the consumer space, can prove itself useful in the cutting edge of engineering and science. 
    Cheers! Great watch!

    This is getting very close to trolling at this point, if you have nothing to contribute, move on, you're not obligated to reply, even less to spread conspiracies.

    Just started shooting on film over the summer. Currently use a Canon EOS 300 and Agfa Vista Plus 200 (which can be obtained for a modest price from Poundland...)

    Joshlikescola got a reaction from Tech_Dreamer in Marvel DVD and Blu Ray too expensive?   
    I would totally agree with you about the image quality and the ownership of a hard copy but I feel like Marvel's Blu-Ray prices are totally out of proportion in comparison to other films...well at least they are where I live...

    What's this about renewables not being enough? It shows what can happen if you just make a plan and stick to it.

    No matter whether the auto update is on or not, the installation shiuld NOT happen when he is.gaming. The OS knows he's running a fullscreen program with constant input. His computer is under honestly pretty heavy load( gaming and streaming). This is plain retard on the microsoft side.

    Joshlikescola got a reaction from Fictionvl in Upgrading from a 700D to new DLSR with a budget of 1500$   
    What are you currently using? If you've already got something half decent then it may not be as worth it.
    It also depends what you're going to use it for. I'd recommend different things for different use cases.
    At that price point the 70D looks pretty solid. Not an expert on lenses but you don't need to go crazy. If you're spending around half your budget on the camera then you can probably get a lens which is pretty solid.
