  • If you’re on a budget, I would offer two suggestions:

    • used DSLRs, and especially their lenses, will be way cheaper than mirrorless
    • if you want to go mirrorless, Sony’s e-mount is probably going to be the most affordable option due to a combination of lots of third party options, vs limited third party options for Canon/Nikon. Sony’s mount has also been around for a while, which gives you more/cheaper used options

    I have no real feedback on the R50 one way or the other. I’ve never used the camera.

    For nocturnal and people, you’re probably going to want a “fast” lens. This is measured as a ratio of focal length to physical aperture diameter and is called a f-stop. The number is 1/x, so smaller numbers = bigger ratio.

    Generally speaking, the fastest lenses are fixed focal length primes. Not zooms. For an everyday lens, a 35mm or 50mm is going to be a decent choice. On a crop sensor, divide these by 1.5 thanks to the crop factor. The actual focal length you land on will depend on how wide you want to get and how far from your subject you’ll be able to get.

    There are some “fastish” zooms available, but they aren’t as fast/sharp as primes and are usually bigger/pricier.

    As for macro, a cheap way of doing that is by adding something like a Raynox DCR-250 to your lens or using an extension tube. You can buy a dedicated macro lens, but IMO unless you’re going to be doing a ton of macro or the lens happens to be a focal length you will use for non-macro work I would go the diopter/extension tube route.

    Seat of pants suggestion? A Nikon D7x00 series camera. They have a built in focus motor, so you can use any Nikon F-moint autofocus lens. Combine that with a Nikon AF-S Nikkor 50mm f/1.4G or a Sigma 30mm f/1.4 DC HSM ART and you’ll be off and running.














  • “Go to college” can be good advice. It really depends where you go to school (in state University vs private or out of state for costs) and what you major in (growing fields, salaries of people with that major, etc). Unfortunately, many of us didn’t get any advice on the second bit.


  • That was similar to my experience. If your parents weren’t providing coaching for what constituted a “good” school or what might be a “good” major you were basically playing roulette.

    Jokes on them, not even the state school wanted me because I was such a slacker in highschool. Working a dead end job, waking up after a year, and enrolling in community college was the best thing that could have happened to me.


  • In the case of at least one school, the state was also cutting back funding.

    I would love for this chart to have two extra lines: the cost of tuition and an inflation adjusted cost of tuition. Without those numbers this chart could simply be “the school spent more while getting constant state funding and made the difference up with tuition”. That wasn’t actually the case here, but the chart doesn’t make it obvious.


  • Websites must use a properly configured robot.txt file with tags specifically telling OpenAI’s bot, GPTBot, to leave the site alone. (OpenAI also has a couple of other bots, ChatGPT-User and OAI-SearchBot, that have their own tags, according to its information page on its crawlers.)

    This sounded weird, so I poked around some. It looks like sites can choose to block all bots and then explicitly allow some (eg Google/Bing). If you want to be choosy as an admin, you’re going to have to put some work in. That sucks. It’s almost like bots need to be typed for something like ‘AI’, ‘search’, ‘archival’, etc…
