My UPS started squawking one Friday evening, the tell-tale sign that the battery was dead or dying. When that happens, it’s time to either replace the UPS battery, or replace the entire UPS. Hopefully you can just replace the battery. Here’s how to replace your UPS battery.
Readers of a certain age will remember CompUSA, a defunct big-box computer retailer. What happened to CompUSA? It went out of business, then came back as an undead brand, then went away again.
In some ways, CompUSA was the epitome of 1990s computer retail. It had huge big box stores with aisles of software and upgrades. It sold desktop computers, including its own house brand, Compudyne, manufactured for CompUSA by Acer. But the business model didn’t work as well in the 21st century.
Micro Center sells a pair of $5 USB-powered speakers. You’re either going to read the next sentence or you aren’t.
Still with me? Great. Let’s talk about them.
My neighbor asked me for advice on setting up wi-fi in his new house. I realized it’s been a while since I’ve written about wi-fi, and it’s never been cheaper or easier to blanket your house and yard with a good signal.
Blanketing your house and yard while remaining secure, though, is still important.
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.)
So, a relative’s PC was getting a bit aged, and runs Windows XP, barely, so I talked them into an upgrade. I noticed that Micro Center had HP/Compaq DC5700s for $99. They were standard issue office PCs a few years ago, and there are a lot of them in the refurb channel. We went and got one over the weekend.
“What are you going to do with that?” the sales rep asked. “We only use them as cash registers.”
“Word processing,” I said.
“You sure you want to run Windows 7 on an 8-year-old PC?”
“I wrote the book on running Windows on older PCs. Literally. It’ll be fine.”
I hate calling rank like that, but sometimes it’s what you have to do.
And really, for $99, it’s awfully good. Web browsing is plenty fast, Libre Office runs fine on it, and think about it. Windows 7 retails for $100-$109. So it’s like getting the hardware for free. Or Windows for free, however you want to look at it.
Last year I bought my mother in law a D-Link router, an oddball DIR-615 revision E1 that was only sold at a few stores. It was supposed to be a Fry’s exclusive, but I bought hers at Micro Center. It worked for a while, then gave her trouble, so this year I was working with it again, and when I was setting it up, I noticed it had some security vulnerabilities–remote code execution, UPnP vulnerabilities, and who knows what else. So that got me some practice upgrading a D-Link DIR-615 to DD-WRT.
DD-WRT’s track record and attitude towards security research could be better, but I’d rather trust my mother in law to DD-WRT’s B+ security than D-Link’s F.
My mom asked me a few weeks ago to recommend a tablet or e-reader. She’s really only interested in reading, so that pretty much answered half the question. You can read on a tablet, of course, but when you sit down to read on one, it’s almost a guarantee you’ll end up doing more than just read a book. You’ll see that e-mail notification and you’ll check it, and next thing you know, you’re on to something else.
So… Kobo, Nook, or Kindle? For me, it was an easy decision. The Nook was the best hardware at the time, so I went with a Nook. Ve hev vays to get the books we want onto the hardware we want, but Mom doesn’t want that hassle. She just wants to be able to buy the books she wants and read them right away. Amazon’s done a hardware refresh, so their hardware is as good as any other at this point, if not a little better, and they have the largest library of books, so it was an easy decision. The newest Kindle Paper White it is.
So, the day after it came out, she went to the nearest Best Buy to buy it… and ended up ordering it from Amazon. That practice is called “showrooming,” and retailers hate it, but sometimes they shoot themselves in the foot. This was one of them. Read more
