SSDs are getting a boost

Dave Farquhar Hardware June 18, 2013June 17, 2013intel, PCI Express, pcie, samsung

This year’s high-end laptops (such as the Macbook and Intel Ultrabooks) are going to be sporting SSDs that connect straight to the PCI Express bus, bypassing SATA altogether.

Although the speed increase will be less jarring than the move from discs of spinning rust to memory chips was, it will be noticeable.

AMD hits 5 GHz

Dave Farquhar Hardware June 12, 2013June 11, 2013amd, intel, Intel Core

So, AMD announced a new 8-core CPU running at 5 GHz this week. It’s a bit of a hollow victory, since it basically will match the highest-end Intel Core i7 in performance, in spite of its much higher clock rate and wattage. I’m not sure what the appeal of a 220-watt CPU is, and I’m also not sure why AMD is giving Intel a few months to respond to it, because I’m sure Intel could create a 5 GHz CPU with a comparable thermal rating to compete against it, given the desire.

Also note this is the design that shares a math unit with each pair of integer cores. For some people, this won’t matter at all, but for others, it can be a deal breaker. It’s part of the reason that AMD has to crank the clock rate so high in order to compete. The problem is that Intel can play this game too. AMD scored major points a decade ago by releasing chips that were much more power efficient than Intel’s power-hungry P4. The resulting war was good for us, since now we’re getting good, fast CPUs that use 20 watts. But Intel is winning that war right now. So that means if AMD wants to play that game, Intel has more headroom to climb. If AMD can deliver 5 GHz at 220 watts, all Intel really has to do is deliver 5.1 GHz at 220 watts.

So AMD is taking a chance here. But I suppose it means that, for a time, they’ll be able to sell some CPUs to people who insist on having the fastest-clocked CPU, whether it really means anything performance-wise or not. And they probably can use the money.

No, this doesn’t mean Ubuntu and Linux are giving up

This week, Mark Shuttleworth closed the longstanding Ubuntu bug #1, which simply read, “Microsoft has majority market share.” Because Microsoft didn’t lose its market share lead to Ubuntu, or Red Hat, or some other conventional Linux distribution, some people, including John C. Dvorak, are interpreting this as some kind of surrender.

I don’t see it as surrender at all. Microsoft’s dominant position, which seemed invincible in 2004 when Shuttleworth opened that bug, is slipping away. They still dominate PCs, but PCs as we know it are a shrinking part of the overall computing landscape, and the growth is all happening elsewhere.

I have (or at least had) a reputation as a Microsoft hater. That’s a vast oversimplification. I’m not anti-Microsoft. I’m pro-competition. I’m also pro-Amiga, and I’ll go to my grave maintaining that the death of Amiga set the industry back 20 years. I have Windows and Linux boxes at home, my wife has (believe it or not) an Ipad, and at work I’m more comfortable administering Linux than Windows right now, which seems a bit strange, especially considering it’s a Red Hat derivative and I haven’t touched Red Hat in what seems like 400 years.

What Shuttleworth is acknowledging is that we have something other than a duopoly again, for the first time in more than 20 years, and the industry is innovating and interesting again. Read more

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.

How the IBM PC became the de facto standard for desktop computers

I saw a question on a vintage computing forum this week: How did the IBM PC become the de facto standard for PCs, and the only desktop computer architecture from the 1980s to survive until today?

It’s a very good question, and I think there were several reasons for it. I also think without all of the reasons, the IBM PC wouldn’t have necessarily won. In some regards, of course, it was a hollow victory. IBM has been out of the PC business for a decade now. Its partners Intel and Microsoft, however, reaped the benefits time and again.

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.

No, it doesn’t take a “serious hacker” to crack wi-fi through WPS

Dave Farquhar security March 26, 2013November 22, 20166502, Debit card, intel, john c dvorak, netgear, pc magazine, phone service, wi-fi

John C Dvorak is raving in PC Magazine about Netgear wireless routers and range extenders and how easy WPS makes it to set them up–and providing some very seriously flawed security advice along the way.

“Note that WPS is crackable by serious hackers using brute-force attack, but any SOHO user not dealing with government secrets should be fine.”

Commodore was more than a stock scam

From time to time, I see the phrase “Commodore stock scam” or something similar come up in discussion or in books. Commodore, in case you don’t know, was a high-flying computer company in the 1980s that was literally making computers as quickly as they could sell them while Apple struggled for its survival, and was in the enviable position of being the main supplier of chips for its competitors. Imagine if Intel sold computers at retail next to HP and Dell, while still selling chips to Dell. That was Commodore in 1984. I don’t have 1984 figures, but in 1985, Commodore had 38% of the computer market all to itself. IBM and its clones, combined, had 49%. Apple had 13%.

But a decade later, Commodore had squandered all of that away and was out of business. That’s why Robert X. Cringely sums up Commodore as Irving Gould‘s stock scam, then goes back to writing about Apple.

The real story is more complicated than that. More interesting, too.
