I've got four in a ceiling fixture that were there when I bought the place 4 years ago. They take time to "warm up", but never flicker or buzz, that I can tell. They took the same amount of time back then as they do now, so my guess is that they were just early-ish models that were designed to look like incadescents. I've got two in nightstand lamps, which get power-cycled perhaps a half-dozen times a day, and have been going for 3-4 years so far. I've got a couple more in standing lamps that I don't remember when I installed, and one being used as a porch light that's just been there about 8 months.

I've had fairly good experiences with CFL bulbs, it's interesting to see how many people have had much more negative ones. I guess I've been lucky.

I identify with your school experiences, although maybe not in as extreme a way; I could generally muddle through rote memorization to a certain degree, but my retention was terrible. The understanding was left behind when the specifics faded away...

Anyhow, for me, the "picture" exists, but it's more tactile than visual. There are visual aspects, but it's not how I process most of the information. Loops are spinning wheels when they don't have a clear exit condition, and feel like unrolled spirals when they're "for" loops going over specific ranges. Algorithms seem like they have a size/weight, which corresponds to my idea of how quickly they'll run on a given set of data (although it's not always accurate, yet).

If I don't remember how a section of code works internally, it feels hollow, and when I read the code, it's like looking inside the black-box. If I change something outside the box, I feel the domino effect, and when it hits the box, I need to look inside to see what'll fall over. I can also feel like threading some string through the eye of a needle, when I'm running some value up through a class hierarchy, or something.

I think that the important insight is that a lot of us become very skilled at constructing mental models of what we're working with, and gain some sort of sensory perception (often vision-related) of how the model functions. I think it's telling that (in my case) the world falls away from my perception when I'm working through a complex problem, and closing my eyes sometimes helps, as well.

OP specified old software, new hardware. Sticking a VM (and accompanying modern OS) as a compatibility layer between the two seems sensible, and not necessarily in contradiction of "the rules". OP also mentioned using ARM-based hardware to run their X86 software. My guess is that they're just throwing words at the wall to see what sticks, and that they'll be happy with whichever solution will let them run their older software.

It sounds like the end goal is to run their older software, though. That should be possible, provided library dependencies can be worked out (and emulation of any direct hardware access).

If the goal is to run a complete older system on new hardware, emulation in some form is the best bet. Running the old OS directly on modern hardware isn't likely to be feasible (without extensive modification to the old OS).

I already have a smartwatch, but if I didn't these would be the reasons today I would get one:
(These are all real, existing apps.)

App that ..sends slow-scan video to watch from phone or takes and displays pictures ..sends nav screen to watch ..can display forecast, barometric pressure, wind direction and velocity ..gets full weather report ..lets you activate watch features based on a value on the internet e.g. **buy alert** goog is at $450
or "new post on your blog", etc. ..lets you know your phone needs charging ..keeps you on-time with buzzing alarms ..(maybe not yet) tells you if your flight is on time ..displays your track as you wander around hoping to wander back

Maybe you should have read to the end of the article. Just saying. To quote: "If Comcast’s last-mile of cable connection was available to all competitors under the same terms that gave dial-up service providers access to all copper telephone networks back in the 1990s, we would have more ISPs in more geographical areas.

Fast lanes allow the little guy to have more bandwidth! Less congestion on large backbones is good for everyone. I think the article is exactly right. People have an idea in their head on how the Internet works, but it is not practical or real. Even the little guy can select a colo for a reasonable cost based on the peering of the colo. The is no reason for every little startup to have peering because they just don't have the demand yet. Their transit bandwidth and costs are fine for the time. When they get larger, they could use 3rd party CDN's, then their own CDN, etc, etc.

VoD over coax was using other channels than the channels used for Internet. The thing is, video is not a profitable for cable companies anymore. People have a lot of choices where to get their content. People are cutting cords and therefore can't take advantage of the cable companies VoD service. Cable companies are loosing their vertical integration, not increasing it.
