The SysV ABI is still used to this day, although the specification itself has withered until only two chapters remain[1], and CPU vendors still publish "System V ABI appendix" documents for platforms that System V's authors could not have dreamed of[2].

C as an interface is going to be around for a very long time, like POSIX and OpenGL and the SysV ABI standard. C as an actual language might not - it might wind up as a set of variable types that other languages can map into and out of, like what happened to the rest of the SysV ABI specification.

I think it's from people reporting sports statistics for a player or team as "W:5 L:7" meaning "five wins and seven losses".

Steve Wozniak was incredibly foresighted when designing the Apple II, to make sure that expansion cards could disable the default ROMs and even disable the CPU, making this kind of thing possible. The article mentions a chunk of memory "used by peripheral devices"; every expansion card got its own slice of the address space, so you could plug a card in any slot and it would Just Work (maybe you'd have to tell software what slot the card was in). I was very disappointed when I "upgraded" to a 386 and suddenly cards had to be manually configured to non-conflicting IRQs and I/O addresses.

Pretty much, yeah! The difference is that in Python the function that calculates a single value looks like:

    foo(x)

...while the function that calculates a batch of values looks like:

    [foo(x) for x in somelist]

Meanwhile in Lil (and I'd guess APL and K), the one function works in both situations.

You can get some nice speed-ups in Python by pushing iteration into a list comprehension, because it's more specialised in the byte-code than a for loop. It's a lot easier in Lil, since it often Just Works.

APL and K are still pretty daunting, but I've recently been dabbling in Lil[1], which is something like a cross between K and Lua. I can fall back on regular procedural code when I need to, but I appreciate being able to do things like:

    127 * sin (range sample_rate)*2*pi*freq_hz/sample_rate

This produces one second audio-clip of a "freq_hz" sine-wave, at the given sample-rate. The "range sample_rate" produces a list of integers from 0 to sample_rate, and all the other multiplications and divisions vectorise to apply to every item in the list. Even the "sin" operator transparently works on a list.

It also took me a little while to get used to the operator precedence (always right-to-left, no matter what), but it does indeed make expressions (and the compiler) simpler. The other thing that impresses me is being able to say:

    maximum:if x > y x else y end

...without grouping symbols around the condition or the statements. Well, I guess "end" is kind of a grouping symbol, but the language feels very clean and concise and fluent.

It isn't really related to the Infocom that released the Zork games, except in a legal sense. Infocom was sold to Activision in 1986, and shut down as a studio in 1989. Circuit's Edge was published in 1990, labelled "Infocom" but just because that's the brand Activision chose to market it under.

Brøderbund was the publisher of "Stunts", but not the developer. The developer was Distinctive Software Inc. who had previously developed the hit games Test Drive and Test Drive II: The Duel for Accolade. For whatever reason, Accolade developed Test Drive III in-house, and DSI developed Stunts on their own.

After Stunts, DSI got bought by Electronic Arts. They were briefly "Pioneer Productions" (or at least, people from DSI were part of that group within EA) and made the original Need For Speed, but eventually became just a part of EA Canada.

From the PuTTY FAQ: https://www.chiark.greenend.org.uk/~sgtatham/putty/faq.html#...

Would you like me to register you a nicer domain name?

No, thank you. Even if you can find one (most of them seem to have been registered already, by people who didn't ask whether we actually wanted it before they applied), we're happy with the PuTTY web site being exactly where it is. It's not hard to find (just type ‘putty’ into google.com and we're the first link returned), and we don't believe the administrative hassle of moving the site would be worth the benefit.

I wonder if they changed their mind because Google ceased to be a reliable way to find them.

The old 68k Macs are emulated with Basilisk II, which shims the mouse driver so it can just take mouse events from the host OS and move the cursor to the corresponding pixel on screen. The PowerPC Macs and NeXT boxes are emulated with a lower-level emulator that wants to get raw deltas from the mouse, not an absolute pixel position. If you just wave the mouse over the emulator, you'll get something approximating the expected movement (but much slower); once you click on the emulator it captures the mouse and you can use it as intended.

I agree it would be nice to have an "untransformed" view of the screen; I suspect the site might have been designed with the expectation of a high-DPI screen.

It took me a while to figure out that the nice product shots of Mac computers were actually live, interactive copies of the relevant operating system, running under emulation. Even the laptops with the screen at a weird angle from the camera.

And the emulator tracks whether you've done the things mentioned in the article, like open a particular control panel or tried a particular menu option.

This is amazing.
