  1. Find businesses big and small who are actually purchasing multiple top-end Mac Pro's or otherwise equivalent $50k desktop machines. I'm really interested in hearing about their use cases and what factors they considered when making the purchase. How do they benefit from Xeon processors and ECC memory? What about >1TB of memory? How does having desktop machines compare to utilizing servers/clusters/cloud computing? Inspired by this thread
  2. Sure but a bad LCD can also have unevenly lit pixels Ok, I can see what your point is and I could get behind that. But this is still just an issue of alignment/calibration; once that's done you should be able to address and light up individual phosphor sites (aka pixels), albeit with some imprecision. A pixel is a single point in an organized array which creates a raster image. It doesn't matter what technology is being used; it could be a bunch of candles arranged on a grid to make an image. As long as they're discrete units on an organized array, I'd call them pixels.
  3. Yes you are correct, monochrome CRT's and vector displays do not have masks and therefore do not have pixels. But color CRT's definitely do. I dunno, the CRT "pixels" look pretty much the same as a modern LCD certified pixel.
  4. The dots aka "pixels" on a CRT are physically defined and separated by a shadow mask. So yes CRT's have pixels and a maximum possible resolution.
  5. I don't know Canon lenses so I can't make any specific EF lens recommendations, but I'd look at getting a fast wide angle like a 16-35mm and a mid-range zoom. For 6K video you don't want to skimp on the lenses, be prepared to pay for the top-level pro lenses. Even better take a took at getting cine lenses for this camera. Don't forget to buy a variable ND filter as well or you'll be constantly overexposed. As an owner of the original BMPCC I generally concur with the other posters. The BMPCC 6K is not a beginners camera and I argue its not a run-and-gun camera either. It's a cinema camera meant for studio work or at least thoroughly planned shoots. In addition to some of things already mentioned (AF, stability, no shooter-aids etc.) there's post-production challenges as well. Are you prepared to work with 6K RAW footage? First off the data quantity is enormous, about 20-30GB per minute. One day of shooting will yield multiple terabytes of data. Do you have the in-camera storage cards for this? Do you have the hard drives and data storage system for backing up and archiving this footage? For actually editing 6K RAW you'll need a beast of a computer. Additionally you should check RAW compatibility with your editing software of choice; it may not work natively adding another step to the process. Then there's color grading, which may be the hardest part of the whole process to do really well. Have you ever color graded before? If you have a tight budget then why are you looking at the BMPCC 6K? The camera is only one piece of a much larger and much more costly system. Have you priced out everything you'll need to actually shoot with the BMPCC? I'd highly suggest that you rent a BPMCC for a day and see if you are prepared to deal with all its short-comings before you commit to purchasing.
  6. If a ship or submarine is passing through a canal or harbor or shallow water they will typically have a map or other indicator of how deep the water is. They don't want to hit the bottom with their boat so they need to know how much of the boat is under water. No simpler way than just looking at the side of the hull.
  7. They're markings used to measure how much of the submarine is below the surface
  8. Unless you have a source to get the computer and parts for free, any amount of money will be better spent on something newer. There aren't many options to upgrade a 2008 MP and if you spec it out with all the best compatible parts there's nothing left to upgrade down the line. AND you'll still be stuck with 2008-level performance.
  9. Start with a general language like C++ or Python. It will give you a good base to learn other languages from. If I were evaluating a job app I'd be looking for someone with a wide breadth of experience which shows they will be ready to learn and develop new skills as technology and demands evolve. We might be using Python a lot today, but we may be using something entirely different in ten years.
  10. The oldest camera I have is a Kodak Flash Bantam circa 1947-1953. It still works just fine, though no one makes 828 film anymore so I either have to find expired film or cut my own. The oldest digital camera I have is an Agfa 1680 from 1999. I haven't toyed with it for some time now but it should still be working. The oldest camera I use regularly is my Hasselblad 500 C/M with dated manufacture in 1985.
  11. If it was my oven I'd probably just clean it really well with some solvent, then follow up with some soap and water. The quantity of toxic material released from baking the card is so small (if any at all) that a good scrub will remove it all. Replacing the whole oven is way overreacting IMO.
  12. A good test I like is that if you have memories of 9/11/01 then you're a millennial, if you were too young to remember or not born yet you're a Gen Z
  13. Honestly I would try to get a longer lens, at least 200mm but preferably more. I shot the 2017 eclipse with 300mm and it left a lot to be desired. As for solar filter, the Baader film is the best so anything with that should be great. Make sure it’s securely fitted on your lens. You really don’t want it accidentally falling off. For glasses check that it has ISO certification. Make sure you’ve got a good sturdy tripod and preferably a remote shutter release. A tracking mount would be ideal but I’m guessing that’s out of your price range. You should have plenty of time before/during the eclipse to dial in your exposure. Go with manual everything, unless some clouds blow in the sun won’t be changing brightness so once you’ve got everything set you’re good. Without a tracking mount you’ll want to stick with a fast shutter speed. You’ll also probably want to stop down your lens by one or two stops to get the sharpest image. Take your time with focus using live mode to zoom in on the edge of the solar disk and get it as sharp as you can. If you’ve got the time try doing some solar photography before hand to practice. The sun is going to be the same on any given day so you’ll get an idea of what to expect.
  14. I've actually had Amazon CS reps tell me to place a new order and return the faulty one. It's easier for Amazon to just send a new product ASAP and get the return and handle it normally than trying to do some kind of exchange or RMA. Of course this only works within the 30 day return window (in the US).
