You can drop the last line---make already knows the incantations to compile a C file.

It would probably work for a Coco3, as the Color BASIC and Extended Color BASIC ROMS didn't change much (there was an additional ROM to support the extra graphics modes).

The 8086 was released in '78 (or thereabouts). 64K of RAM was very expensive at the time, and wasting 256 bytes just to align segments would have been extravagant. Also, the 8086 was meant as a stop-gap product until the Intel 432 wa

I don't think Dreamweaver was "too complicated" [1] and I recall seeing tons of sites in the 90s, some managed by hand, some by program (whether custom written or commercial). Yes, that might have been early adapters of tech

We've forgotten. Back in the mid-90s, most ISPs gave space to users to host a website. There were produts like Dreamweaver and (although I hate mentioning it) Microsoft FrontPage that provided WYSIWYG editing of HTML and used FTP to u

I wrote my own 6809 assembler [1] largely just because, and I ended up adding a 6809 emulator to it, so I can run tests during the assembly phase. I'm only aware of one other assembler (a 6502 one) that can do this. It's a fun p

The first link is to the MC6839, which is covered already in the blog post. The second link is the Lennart Beschop's floating point routines, which is what the post is about. > ROM of MO6/TO7 Do you mean the MC6839 here? Or s

First off, the assembler is for a Motorola 6809, which is not a 6502. Second, one benchmark result I found [1] showed it being a bit slower than some alternatives. [1] https://www.callapple.org/programming/sane-progr

My first experience with computers was 45 years ago, and a "byte" back then was defined as an 8-bit quantity. And in the intervening 45 years, I've never come across a different meaning for "byte". I'll ask f

Some idiomatic C code to copy a string (I'm not saying this is good C code, but it's just an example): while(*d++ = *s++) ; On the Motorola 68000 (based somewhat on the PDP-11) the code would look like: loop:

C++ programmers decided against NULL, and for well over a decade, recommended using a plain 0. It was only recently that they came up with a new name: nullptr. Sigh.

Not quite. Going back to the bottling example, a bottle has to be filled, capped, then labeled. At time 1, 1 bottle is filling up, pipeline is advanced. At time 2, bottle 2 is filling up, bottle 1 is being capped, pipeline is advanced.

My blog [1] is mostly dynamic (only static pages are the main index.html page and the various feed files) and uses a simple template based system, and each entry is a separate file. The engine [2] also supports adding new entries via POST

But you had a theory you could test. The hardest bug I had to debug (over a month of constant work) was very difficult to reproduce on demand. The program (a single threaded server) would crash after running a few hours in production. I

One, CGI scripts are run as a separate process, so running valgrind on the web server won't get status about the CGI program. Two, it would probably generate a ton of output not related to the CGI program even if it did work. Three,

Back when most writers used typewriters, the convention was to use the underscore to mark text that was to be italicized. And because they were using typewriters, they would backspace to the first letter of a word or phrase, then type the
