The 6502-family CPUs in Commodore 8-bit computers famously used 64K of RAM at a time. But in 1985, Commodore introduced a cartridge that added up to 512K of RAM to the 128. Commodore followed up soon after with a 256K cartridge for the 64. How did Commodore RAM expansion units work?
When I first installed it, I thought it was pretty pointless to try to optimize Windows 10. Of course, I installed it from scratch on a computer with an SSD and 16 gigs of RAM. Then I upgraded a couple of computers from Windows 7 to Windows 10, and I started to see why some people might not like Windows 10 all that much.
Upgraded systems almost always run slow, but I’d forgotten how much slower. And while you didn’t have to do much to Windows 7 to make it fast–that’s one reason people liked it–I find some Windows 10 optimization seems to be necessary.
The Amiga had a command line, or CLI. It was a rather powerful CLI, especially for its time. But there are a number of differences between AmigaDOS and other operating systems you may be familiar with. These are the common AmigaDOS commands and their equivalents from other operating systems like DOS, Windows, Unix or Linux.
I’ve never seen a primer that relates or cross-references Amiga commands to Windows and Unix. So I wrote one. I hope it helps you understand your Amiga better. Because Amiga is sometimes like Windows and sometimes it’s like Unix, I think it might. And maybe, just maybe, you’ll learn something you didn’t know about Windows or Unix too.
Last week Apple released a bunch of patches up and down its product line. One of the vulnerabilities it fixed in OS X was a vulnerability in its font parser.
In the past you could mitigate vulnerabilities like this by only installing fonts from trusted sources, but since it’s now possible for web pages to transmit fonts along with other content, there’s a limitless number of untrusted fonts out there in the world.
Since it may take a while for all of the major operating systems to shake out all of the problems in their font subsystems, that’s the reason I’ve recommended filtering fonts at the proxy.
Microsoft rushed out an out-of-band patch, MS15-078, to deal with active exploits in their font driver yesterday. Since pushing out patches takes time, my boss asked me what we could do to mitigate the issue in the meantime.
The biggest threat, by far, is exploit-bearing fonts being downloaded from web sites. Ideally you only install trusted fonts from trusted sources locally on your workstations, right? If not, I suggest you start that practice as well.
You have a couple of options when it comes to blocking fonts in browsers.
A rather hastily written and sloppily edited piece showed up on Slashdot yesterday morning that caught my attention, because it was about the Amiga 2000. The Amiga 2000 is a dear machine to me; in 1991, our family upgraded to one from a Commodore 128. I still have both machines, and there isn’t much that I know today that I didn’t first experience on one of those two machines.
Although I think the piece was little more than a used computer store’s effort to unload some hard-to-move inventory, I do agree with the premise. For a machine that had a tremendous impact on the world as we know it today, the A2000 is criminally unknown. Read more
I’ve read that e-readers change the way you read, but of course up until this week I’ve never experienced it firsthand. I can say that in my limited experience with a Nook Simple Touch, I’ve already noticed it.
