Now the question is who did it better, 8-bit guy or Technology Connections?

Technology connections, and it’s not particularly close.

He mangles some of the pros and cons of CRTs towards the end.
They aren’t going to be indefinitely reliable. The phosphor goes bad over time and makes for a weaker image. Doubly so for color phosphors. Some of them are aging better than others, but that’s survivorship bias. We might be looking at the last decade where those old CRTs can still be in anything close to widespread use.
CRTs do have latency, and this is something a lot of people get wrong. A modern flatscreen display can have better latency than CRTs when the hardware takes advantage of it.
The standard way of measuring latency is at the halfway point of the screen. For NTSC running at 60Hz (which is interlaced down to 30fps (roughly)), that means we have 8.33ms of latency. If you were to hit the button the moment the screen starts the next draw, and the CPU miraculously processes it in time for the draw, then it takes that long for the screen to be drawn to the halfway point and we take our measurement.
An LCD can have a response time of less than 2ms. That’s on top of the frame draw time, which can easily be 120Hz on modern systems (or more; quite a bit more in some cases). That means you’re looking at (1 / 120) + 2 = 10.3ms of latency, provided your GPU keeps up at 120 fps. Note that this is comparable to a PAL console (which runs at 50Hz) on CRT. A 200Hz LCD with fast pixel response times is superior to NTSC CRTs. >400Hz is running up against the human limit to distinguish frame changes, and we’re getting there with some high end LCDs right now.
When talking about retro consoles, we’re limited by the hardware feeding the display, and the frame can’t start drawing until the console has transmitted everything. So then you’re looking at the 2ms LCD draw time on top of a full frame time, which for NTSC would be (1 / 60) + 2 = 18.7ms. Which is why lightguns can’t work.

I used to watch this guy. Then about 6 years or so ago. Then one video he gets on, and starts berating his viewers for sending him gifts, and fan art.
His explaination was something along the lines of him not having enough space for all the stuff. And that’s fine. I understand not having space.
But then he just goes ON AND ON AND ON about it. In a pretty disrespectful manner.
He could have just said something like “As a side note, while I appriciate everybody thinking of me, I just don’t have the space for it all.
So if you’d like to send me art, I would much prefer digital art over something physical. I love the enthusiasm, I just have nowhere to put it…”
That would have been understandable.
Instead, he said something more along the lines of “I’m getting way too much fan packages from you guys. LOOK AT MY LIVING ROOM!!! I can’t take it all! This needs to stop! It’s making me angry. You guys are tweeting me that I don’t thank you for your hard work. I haven’t even opened the box! How am I supposed to know what you sent me???”
And ever since then, I’ve seen him as an unappriciative dick. I understand the need to stop the incoming flow of packages coming in, but there’s a nice way to do that.

I also used to watch this guy very regularly but stopped when I found out he’s a political gun nut who open carries his AR-15 specifically to anger people and make them uncomfortable.
There’s a video of him inside a store with a rifle ranting about some poor politician and their effort to prevent gun violence. Easy to find if you search for it.
Lost_My_Mind@lemmy.world 4 months ago
I just remembered the line that made me stop watching. It was him saying that any future packages would be thrown in the trash.
This after ranting for like 3 minutes that too many people love him, and gift him so much stuff.
I was brought up to appriciate every little thing people gave me. Even as a kid…that knock off power ranger that has a hollow inside, made of cheap rubbery plastic? “Thank you for the gift!”
So to see him say “I will throw any future packages in the trash” just felt like a slap in the face to any fans he may have had.
So I stopped being a fan. It’s easy to unsubscribe on youtube.

If you care to watch. This is his most current views on the subject if you care to watch. piped.video/watch?v=lGtSRb1q99o

I stopped watching when he got that one rare IBM workstation and sloppily dremeled in all the the screws to open it because he was too lazy to go to the store to buy a screwdriver. That was before I even heard about this and the stupid gun stuff. I know it’s like a minor thing and he only damaged screws and sheet metal parts that could in theory be replaced with a medium amount of difficulty, but I just can’t imagine intentionally damaging something very uncommon because you’re too lazy to buy a screwdriver

Videos like that I’m always amazed the creator even bothers uploading. I’d be so fucking embarassed it would never see the light of day.
But I guess its sunk cost fallacy. Gotta get that content out there I spent a week working on. I guess I can appreciate that. Theres also something to be said about being honest about your fuckups. I was so embarassed for him I noped out of that video so I dont really know how it ended, but I dont recall there being much humility about it?

…who doesn’t have a screwdriver??? HE DISASSEMBLES ELECTRONICS OFTEN FOR A LIVING!!! WTF???
This only raises MORE questions!

I get the same vibe, i still watch him, but not as intently as before. He has a tendency to do exactly that, and he generally fails to respectfully address any concerns he has. He just sorta acts annoyed and goes on tangents. His content in good, but his personality isn't
firewallfail@lemmy.world 4 months ago
I’ve been finding his content hasn’t been as good for the last couple years, maybe just from the random rants he tosses in for no reason. Then he went on a little rant recently about how he isn’t making as much money from YouTube anymore and I unsubscribed.

Devils advocate:
If you’re known as a guy that like Pokémon cards and people keep gifting you Weedle’s (one of the lowest powered and most common cards in the game), then after a while you’re going to be like “thanks guys, I know you want to gift me and to not just throw the card away, but these are worth literally nothing to me and I’ll just be throwing them away myself”.
