Windows vs. Linux kernel performance

An anonymous Microsoft developer spilled some juicy opinions about why Windows kernel performance isn’t all it could be and answered some longstanding questions about Windows vs. Linux kernel performance in the process. Although he has recanted much of what he said, some of his insights make a ton of sense.

“Computer Maintenance Department” called me again from India

So, “Peggy” from “Computer Maintenance Department” called me again last night. This time I decided to mess with him a bit more. This is the second time.

(No, “Peggy” wasn’t his real name, nor did he identify himself as “Peggy,” but that’s the name I’ll use, thanks to that old Discover commercial.)

Don’t read too much into the PC sales drop just yet

Dave Farquhar Retro Computing, Windows April 17, 2013November 3, 20251980s, 1990s, amd, amiga, apple, asus, IBM, kingston, lenovo, vista, windows 2000, windows 7, windows 8, windows 98, windows me, windows nt, Windows Vista, Windows XP

If you’ve been paying any attention at all, you probably know that new PC sales are in the toilet–out of the five biggest vendors, the only one whose sales managed to hold steady in Q1 2013 was Lenovo, while the other four saw a sales decline. So now Slashdot linked to a ZDNet piece stating that Windows is over, and said it must be true because ZDNet always sides with Microsoft.

Let’s not read too much into that. The author of the piece is a longtime open-source advocate. The points he raises are completely valid, but if there’s one person who’s going to take Microsoft to task, it’s Steven Vaughan-Nichols.

Microsoft has a long road ahead, but there is precedent for salvaging the boondoggle known as Windows 8. And I don’t think Windows 8 is the only factor here. Read more

The AMI BIOS breach of 2013

Dave Farquhar security April 6, 2013November 30, 2018amd, AMI, garage sale, intel, malware, UEFI

A security professional’s nightmare happened to AMI this week. Tons of confidential data, including the source code for the UEFI BIOS for Intel Ivy Bridge-based systems and an AMI-owned private key for digital signatures, turned up on a wide-open FTP server for all comers to download anonymously. This AMI BIOS breach has numerous implications.

The implications are nearly limitless. To a malware author, this is like finding a hollowed-out book at a garage sale stuffed with $100 bills with a 25-cent price sticker on the front. If you’re a budding security professional, count on being asked in job interviews why you need to protect confidential information. The next time you get that question, here’s a story you can cite.

Is this a good computer for the money in 2013?

Dave Farquhar Hardware March 27, 2013March 24, 2013amd, dell, intel, Intel Core

My realtor sent me some computer specs this past week and asked for my opinion on it, since I get paid to keep up with this stuff these days and he doesn’t.

I thought my critique of the system might help other people.

Why Intel can’t quit x86

Dave Farquhar Hardware March 10, 2013June 9, 2024amd, apple, DEC, IBM, intel, marvell, motorola, motorola 68k, os x, Steve Jobs, x86

Here’s a nice perspective on Intel’s non-x86 efforts, and why they failed and x86 marched on, despite its weak points, and why Intel can’t quit x86.

Kudos for remembering that Intel made ARM chips.

How the previous week’s headlines flow together

Here are some headlines I read this past week: Dell is trying to take itself private. Microsoft is investing in Dell. Intel is pulling out of the motherboard market. AMD is considering ARM CPUs. And the PC is dead.

It’s all related.

Up and coming low-end Android chips

I decided to dig into what the low-end Android chipmakers like Mediatek and Rockchip are up to, since they’re the ones who are likely to drive prices down.

SSDs might be getting less interesting, but that’s not necessarily bad

Dave Farquhar Hardware January 12, 2013November 3, 2025amd, apple, Ars Technica, CES, consolidation, corsair, intel, kingston, samsung, toshiba, Western Digital

Ars Technica has a story about SSD news coming out of CES.

Basically, they’re predicting that the big news this year will be consolidation and lower prices. That may be bad news for someone who writes about SSDs for a living (I don’t), but good news for consumers. Read more

What to make of this Black Friday’s sub-$200 laptops

It’s still a couple of weeks off, but we already know two retailers will be offering sub-$200 laptops on the day the United States gorges itself on bargains.

The question is, what do you get for your $200 on these minimalist laptops? I’ll answer those questions, then you can decide whether they’re worth $200 and braving the crowds, the weird hours, and likely the cold. (Yes, there are costs beyond the money you spend.) Read more
