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.
“Oh, so you think you’re Mr. Genius Man,” the crackly voice said, drowned out by static caused by his cheap VOIP connection. “Enjoy your broken computer, Mr. Genius Man. Goodbye, Mr. Genius Man.”
So ended 23 minutes of my life that I’ll never get back, but I figure it’s 23 minutes he wasn’t spending scamming someone else. I don’t do it often, but my kids were playing nicely and we were all in the same room, so I guess I don’t regret it too much. Read more
I got my new 64-bit web server up and running today. Now the main task that remains is to get my data moved over to it. I talked myself into going with an Apache setup, since one program I want to run (Webtrees) is designed for Apache and its search engine optimization seems to work better under Apache than Nginx. It’s fast anyway; displaying the 17-person family of Andrew Davis McQueen of Leesville, Mo., briefly consumes 2% of the available CPU time in Webtrees with the APC PHP cache installed and enabled. And that should get better, seeing as newer, faster, better versions of both Apache and PHP were released in the last month.
As I built my new 64-bit web server, I messed up MySQL a couple of times. When you break MySQL beyond repair, here’s how to start over with a fresh MySQL install and a fresh /var/lib/mysql without doing a Windows-like reformat and reinstall of the entire operating system:
People have been asking me a lot of notebook/laptop questions lately, so I figure it’s probably a good time for me to write about them. I’ll tackle reliability first, then I’ll tackle upgrades. Here’s how you can make your laptop more reliable.
About five years ago, I wrote and published a newspaper column titled, “10 Reasons You Shouldn’t Buy a Laptop.” I still think the best way to get a reliable computer is to skip the laptop and get a desktop, but since people are going to buy laptops anyway, here’s what I’ve learned about keeping them reliable.
Buy the extended warranty. My normal response when people ask me if I want these is to say, “I fix these things for a living. I am an extended warranty.”But most laptops have no technician-serviceable parts inside and few technician-replaceable parts inside, let alone user-serviceable stuff. Aside from swapping a hard drive, RAM, or optical drive, a laptop might as well be a car with the hood welded shut.
Plus, a common malady of laptops is a busted screen. The manufacturer’s warranty won’t honor that. I wouldn’t cover it if I were offering extended warranties either, but most extended warranties do. If the warranty costs $150 or less and covers a busted screen, get it. At $300 it’s a tougher sell, seeing as entry-level laptops cost about $600, but I’d even think about them at that price.
Brand matters less than it used to. I used to look at PC Magazine and PC World reliability ratings. Usually people who asked already had their mind made up and bought something other than what I recommended anyway (and then regretted it), but the difference in manufacturers is evaporating. Most laptops are designed by the same engineers and made in the same factories these days regardless of whose name goes on it. And most support is outsourced to India too. I specifically recommended IBM primarily because their support was still U.S.-based, but with the sale of its PC business, that could change at any time now.
So no matter what you buy, you’ll get something of questionable reliability supported by technicians of questionable experience and ability, not that that’s going to matter much because you won’t be able to understand him or her anyway. If the terrible VOIP connection to India will get you if the accent doesn’t.
Buy a really good laptop bag. My laptop has lasted five years. I know at least one person who knows as much or more about computers than I do, but his laptops generally have a shorter life expectancy. The only difference I can see is the laptop bag.
He (along with everyone else I know) uses the typical laptop bags. My bag is an oversized, overweight leather bag. When the bag hits something, it usually leaves a mark. It weighs more than the laptop does, but seems to do an outstanding job of protecting it. I live with the weight. I’d rather have a laptop that works, and besides, I can use the exercise. I’m not exactly buff.
The bag discovery isn’t anything I can take credit for, by the way. The manufacturer messed up the order and included that bag with the laptop as appeasement. So a $150 bag to protect a laptop, whether it costs $600 or $4500, seems to be a good investment. Remember, you can always use the bag for the next laptop, so you only have to buy it once.
On the other extreme, I’ve seen people carry laptops in plastic grocery bags. They deserve all the troubles they get. That’s usually a lot, if you’re wondering.
Don’t put your laptop in overhead storage bins on airplanes. This should go without saying. But I’ve seen people with PhDs do it, so maybe that’s a truth that’s only obvious to computer techs. When the other stuff in the compartment shifts, the bag will get crushed, and that’ll be the end of your laptop screen. When the screen breaks, it’s usually cheaper to buy a new laptop.
Take the laptop as carry-on luggage, and stow it underneath your seat. There’s no other safe place for a laptop on an airplane.
Be aware of the hidden costs. Assuming your laptop makes it beyond its warranty period, there are two things that are as certain as death and taxes: The battery is going to die and need to be replaced, and the same goes for the hard drive.
Batteries aren’t cheap. If it’s under $100, count yourself lucky. And don’t be shocked if it’s $200. Don’t bother buying an extra one now to save for later; it’ll be dead by the time you need it. You might like having a spare to keep charged and swap in when the other one dies though.
Fortunately, laptop hard drives have gotten cheap. You can still spend $200 on a laptop hard drive if you want, but Newegg.com has drives starting in the $60 range.
Make backups. Buy yourself a nice, big memory stick and copy over anything you care about (certainly your My Documents folder at the very least) every day. Laptop hard drives die all the time and usually without warning. So be ready for it. Or get yourself an external USB 2.0 hard drive. A copy of Ghost or a similar program for making images of the internal drive is also useful–that way, when the drive dies, you don’t have to spend all weekend reloading everything.
Get a good laptop surge protector. A portable single-outlet surge protector sells for $10-$20. Get one and use it. Those summertime hiccups that cause your lights to flicker aren’t good for your laptop either, and laptops are a lot more expensive than light bulbs.
Most people buy APC units, but Belkin offers a unit that costs a little less and offers a lot more protection. Expect to pay anywhere from $7-$20. It’s money well spent–you’re protecting a delicate machine that costs several times that.
When looking at a surge protector, more joules (the equivalent of one amp traveling through one ohm of resistance for one second) is better. And if you use the modem in the laptop, don’t forget to plug it into the modem outlet in the surge protector, since surges coming through the phone line can damage the laptop and, in my experience at least, are more likely to do harm.
