Building the machines and running them are two different skillsets. Like building a race car vs driving one.

Its at least somewhat based on the transistor density increase they get from other techniques right? Like “3 nm” is the equivalent transistor size they’d need to get the same transistor density using 2005 chip design.

I had a very similar childhood in the US.

I sat at a booth and played with coloring books while my mom worked in a restaurant’s kitchen, dad’s work was seasonal and very irregular. We didn’t drink the tapwater in our little town because it didn’t smell right and even came out discolored a few times; instead we’d drive to springs where a bunch of other people got their water too.

Imagine going back in time to 2015 and showing this article to someone.

I don’t know much about photography, so forgive me if this is a dumb question, but would something like focus stacking help with this?

That is to say, make the lens less of a bottleneck so you could benefit from a higher resolution sensor.

Anyone interested in this concept should take a look at plan9. Everything is even more of a file there.

Taking a screenshot, for example, can be done with:

cat /dev/screen | topng > screenshot.png

That combined with the way that parent processes can alter their children’s view of the filesystem namespace allows for extremely elegant abstractions. For example, every program just tries to write directly to screen or audio, but the desktop environment redirects their writes to the relevant servers. Which means that, in the absence of those servers, those same programs can run just fine and don’t care whether they’re being multiplexed or not. That also means that the plan9 userspace can be nested inside itself just using the normal mechanisms of how the OS works (that is, without a special tool like Docker).

I see

In your opinion is there anything useful we can do with that part of the radio spectrum as those stations switch off, or are those frequencies going to be silent in the future? Will they be turned over to hobbyists maybe? (or would the power requirements be too high at those frequencies?)

Since the portable radio doesn’t have much power, you may need to use digital modes to get through.

I don’t know much about radio stuff, but ever since I learned about LoRA I’ve wondered what kind of range a station could get if the longwave or AM bands were repurposed for use with a spread spectrum digital protocol. And what kind of bandwidth something like that would have.

I think being able to do datacasting over really long ranges would be useful, so, for example, you could send emergency alerts to people even if the local cell infrastructure was down. But with the way things are headed I guess that role will be taken up by satellites.

Alchemists (correctly) observed that everything in the world was subject to disorder and decay as time progressed, but noted that gold seemed to be immune to this effect (since it is highly resistant to oxidation). Add into that the belief system that they were working with:

• That everything in the world exists on a chain of being from the most corrupt at the bottom to the most noble on top (with god being most high).

• That everything is really the same thing, and through physical processes changes its form, including up and down the chain.

And they belived that if they could figure out how to transmute a lesser metal into a more noble one then they could probably move other things up the chain of being as well. Which is why the Philospher’s Stone was supposed to make people unaging and immortal, and cure all disease, in addition to transmuting lesser metals into gold. Alchemists like John of Rupescissa probably belived that creating the Stone would also bring the world closer to the divine in some way, and it was god’s wish for mortals to do this.

The microcode in integrated CPUs took care of routing your inputs and outputs to where they need to be, and triggering the various arithmetic operations as desired.

In the transition from plugboards to programmed sequence control the thing that took over the task of routing values between registers, through the ALU, and to/from IO ports was the control unit. Microcode being one way to implement functionality in the control unit.

One other approach was to use what was basically a finite state machine, implemented physically in-circuit. The output of that FSM was fed into a series of logic gates along with the current instruction value, with the output of that combination being connected to the control lines of the various CPU elements. Thus the desired switching/routing behavior occured.

Modern chips are really complicated hybrids of microcode and a ton of interacting finite state machines. Especially in x86 complex or less commonly used instructions will be implemented in microcode, whereas simple/common instructions will be implemented by being “hardwired”, somewhat similar to the FSM technique described above (although probably more complicated).

Philips Ultra Efficient bulbs use only 4 watts, and they have a glass bulb and metal base, so they might feel cool to the touch anyway. Or at least feel plausibly the same temperature as the room, depending on how hot it is in there.

From the wording at the top it sounds like this was just for fun and probably ungraded.

I don’t even necessarily disagree, but I think that position is unfalsifiable because if the example is a highly popular program then “that doesn’t count because it’s big”, and if it has a small user base then “of course it’s small, it has a shitty name”.
