Here’s a good question I heard the other day: What’s the difference between a CPU and cores, or the difference between the number of CPUs and the number of cores in a system? The CPU vs core or core vs processor distinction, it turns out, is subtle.
As far as the operating system is concerned, there is no difference, but I’ll explain why. For you, there might be a difference.
I’ve been building PCs for more than 20 years and I tend to keep them a very long time, so it occurred to me that someone might be interested in what I look for in a motherboard to ensure both a long, reliable life and a long useful life.
Technology has changed a lot but what I look for has remained surprisingly consistent over the years.
An 8086-series microprocessor, the 8088, powered the original IBM PC. Its direct descendants power PCs to this day. Not only that, they power modern Macs too. This was always controversial, especially running Mac OS on Intel chips. Why? What are the disadvantages of the 8086 microprocessor?
I got an HP Elitebook 8440p because I wanted something a little newer and faster than my old Dell E1505. It was certainly newer and faster, but it had a problem. Every morning it greeted me with a BSOD. That E1505 was getting older and it had its own quirks, but I don’t remember it ever bluescreening on me. Here’s how I fixed the bluescreens I got with the HP Elitebook 8440p and Windows 10.
Not only did it bluescreen, but the behavior seemed pretty consistent. Two days in a row, I woke the laptop up from hibernation, and about nine minutes later, it bluescreened.
Overclocking didn’t start in the 90s, and it wasn’t limited to PCs either. Here’s a history of overclocking from a guy who did it some, and talked to guys who did it a lot in the 80s.
I don’t recommend overclocking, and today Microsoft can prove it’s a bad idea. But overclocking has a long and colorful history. It’s less common than it used to be, perhaps. But it’s not completely extinct.
Someone asked me the other day about buying used computer parts. I recommend it actually, although I more frequently buy the whole computer. But you can save a lot of money and get higher quality by buying used computer parts.
What happened to Packard Bell? It ceased operations in the United States in 2000, after a 14-year reign of terror on the consumer market.
But there’s more to the story than that. The Packard Bell story is a brilliant piece of marketing. The computers were terrible, but the marketing was as good as it gets. And that’s one of the reasons people remember it as one of the more prominent of the 90s computer brands, even if they don’t usually remember it fondly.
After I imaged the disks from a failing Debian server to newer hardware, I got the error message ifdown: Interface eth0 not configured after issuing the command ifdown eth0. There’s not a lot of documentation out there about this so hopefully this writeup will help you if you’re getting this puzzling message.
This should be the same in Ubuntu, for what it’s worth.

Here’s an interesting question I got recently: Will ARM overtake x86?
I think the answer depends on how you define “overtake.”
In the shadow of Windows 10, Intel and Micron announced a new type of persistent memory that’s 1,000 times faster than the flash memory in today’s SSDs. It’s still not as fast as DRAM, but it’s fast enough that it’s going to make things possible that weren’t before.
Intel and Micron weren’t the first to develop something like this–HP has been working on something similar for years–but HP hoped the product would be out by now, and as far as I know, it didn’t happen. It looks like Intel and Micron’s similar technology is going to happen.
