Don’t buy a “desktop replacement” laptop

Dave Farquhar Hardware, Saving money October 23, 2014November 29, 2015amd, asus, dell, Dell Inspiron, IBM, lifehacker, memory slots, model m

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. Read more

The wrong way to reboot a server

Dave Farquhar Hardware, War Stories October 17, 2014November 27, 2018datacenter, dell, hp

In my day, I did plenty of hardware maintenance in the field. In fact, the only time one of my bosses ever saw me at work, I was swapping out failed memory in a server.

“How’d you know it needed to be done?” he asked.

“It told me.” That’s why I always loved HP Proliant servers. My boss looked confused at my answer but didn’t ask me to elaborate.

But not all of my field maintenance always went quite so smoothly. Read more

HP splits in two.

Don’t you feel like trying something new
Don’t you feel like breaking out
Or breaking us in two
You don’t do the things that I do
You want to do things I can’t do
Always something breaking us in two –Joe Jackson

After years of buying up companies, HP is splitting up. While that’s probably more prudent that exiting the desktop PC business, which is another idea they flirted with in the past, it’s anyone’s guess how this is going to work out.

But it’s what all the cool kids are doing, so it’s what the investors want, and that means HP is going to do it. Read more

WMIC invalid global switch – solved

Dave Farquhar Windows August 14, 2014October 12, 2017dell, hp, lenovo

I use WMIC a lot to gather data in my job. Querying computers that have dashes (a.k.a. the minus sign, the “-” character) in the names cause an error message that says “invalid global switch.” Microsoft operating systems use the dash as a reserved character to indicate command options. Here’s how to get rid of the WMIC invalid global switch problem.

Windows Vista’s market share is growing. After seeing 8.1, I know why

Dave Farquhar Software, Windows August 13, 2014April 15, 2017acer, citrix, COA, compaq, dell, hp, Microsoft Security Essentials, vista, VPN, windows 7, windows 8, Windows Vista

I installed Windows Vista last week. I need a legal copy of a supported version of Windows to use to VPN in to work and run the corporate Citrix client. Vista fit the bill. It’s better than 8.1, and it’s supported until April 2017. I always hated Vista, but 8 and 8.1 made me realize it could have been a lot worse, and on recent hardware Vista does OK. It still prompts you for admin rights too much and too slowly and makes you work too hard to click yes, but at least you can find stuff. Read more

What I did for Mother’s Day

Last month, Rapid7’s Trey Ford appealed to security professionals:

You have an opportunity to be an ambassador. When you see XP out there, have an adult conversation, educate in terms that others will appreciate. Your actions and words reflect on the entire community.
As the family CIO/CSO – look for the smart investment. There are options that will make your life easier. A small investment is a lot easier to stomach than compromised shopping/banking/credit card credentials (or identity theft.)

Macs aren’t the only computers that last forever

Dave Farquhar Hardware March 17, 2014February 5, 2022apple, dell, hp, pentium ii, reminders, Windows XP

In the midst of Microsoft reminding everyone that Windows XP’s doomsday is less than a month away, Apple quietly announced that Mac OS 10.6’s doomsday was sometime last year, and no more security updates would be forthcoming for Snow Leopard.

That led to this piece about why anyone would still want to run Snow Leopard. Well, there are reasons for it–and for that matter, there are reasons why they would want/need to step back to 10.5 (Leopard). I don’t disagree with that part at all, but I do disagree with the point at the end, where he says that if you want a computer that lasts a long time, you have to buy a Mac.

Let me remind you that Microsoft is sending out reminders to people that it’s time to migrate off an operating system that hasn’t been generally available on new consumer PCs since 2007. Read more

The Post-Dispatch may be giving the wrong idea about the dollar value of vintage computers

Disclaimer: I wrote this article back in 2014. I leave it here as a snapshot of the state of how things were in 2014. The situation at the time you are reading this is likely different.

Articles like Top 10 collectibles for value, from the Post-Dispatch this week, frequently make me nervous, mostly because of statements like this one:

[D]id you know that computer parts can bring home cash, too?

Statements like that tend to get people’s hopes up way too high. I find the timing interesting though, seeing as a TRS-80 Model 1 sold at a St. Louis estate sale this past weekend. The estate seller’s reaction? “Normally you can’t give that stuff away.”

The problem with Lifehacker’s computer manufacturer ranking

Dave Farquhar Hardware November 20, 2013October 11, 2019android, apple, asus, black friday, dell, hp, lifehacker, toshiba, Western Digital

Lifehacker posted a controversial computer manufacturer ranking this week. I’m not sure how you can rank anything with Apple, HP, and Dell in it and not be controversial–someone’s going to be offended that their favorite isn’t at the top and their least favorite isn’t dead last–and while I agree with it more than I disagree with it, there are at least three problems with it.

So, let’s go. Read more

Cleaning a hard drive with Linux

Dave Farquhar security November 19, 2013December 3, 2015dell, random data

A friend asked me a favor in church one Sunday: He had a computer he wanted to clean off so he could donate it, but since it had financial data on it, he wanted to make sure it was cleaned up securely. I recommended Darik’s Boot and Nuke, which I’ve recommended before, but he wasn’t able to get it working for whatever reason. So he asked if I would clean it if he dropped it off. I agreed.

Rather than burn a DBAN disc, I just took the hard drive out and put it in a Linux box and wiped it with that. It was easier than trying to find a blank CD.
