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.

I was at church on Sunday and the video projection wasn’t working. After a few minutes of watching everyone struggle, I volunteered to take a look, and working together, we were able to get the video working again using a simple, repeatable methodology: Using the OSI model to troubleshoot video.
I’m going to share that methodology now.

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?
It’s easier than it sounds. As far as the operating system is concerned, there is no difference, but I’ll explain why.

So the sales fliers for the 2014 Christmas shopping season are out, and I’m seeing tons of cheap laptops. If you only have $200 to spend, they have something for you.
Some of them look like they’re even worth having. Yes, I’m shocked too. Here’s how to figure out which ones are worth taking home, and which ones are best left for some other sucker. Whether you’re shopping for yourself or someone else, you’ll probably want to keep the following in mind.

FTDI is a company that makes computer chips for USB peripherals. Their chips are frequently cloned, which is an issue they have a right to deal with. But they have to be careful.
Breaking suspected cloned chips that consumers bought in good faith is the wrong answer. If I did that, it would be called hacking, and I would be sitting in jail right now, and probably would be facing a quarter-century in prison. Continue reading FTDI needs to be charged under the Computer Fraud and Abuse Act
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.
Of course what to look for has changed to some degree over the years, but this is what I look for in the mid-2010s.

I found this oldie but goodie Lifehacker article: When two computers are cheaper than one. It advocates buying a cheap laptop and building a desktop PC to meet your computing needs.
I think it makes a lot of sense. A few weeks ago, a coworker asked me what the most I would be willing to pay for a laptop. I hesitated, thought for a while, and said you might be able to convince me to spend $600. “Wow,” he said. “I’m considering a $3,500 laptop.”
I wouldn’t. Continue reading Don’t buy a “desktop replacement” laptop
IBM announced yesterday that it had a terrible quarter. They missed earnings, the stock plunged, and Warren Buffett lost a billion dollars.
Everyone assumes Warren Buffett is worried, or livid, and selling off the stock like it’s on fire. Continue reading Why we can’t have nice things: The reaction to IBM’s big black and blue quarter
