Stupid Geek Tip: Cut and Paste Long Passwords and Keys!

Wednesday, October 22nd, 2008

You’ve set up your home wireless network with a 26-digit hexadecimal key, but it’s a pain in the rear to keep typing the number in.  What makes it even more irksome is that the box on your computer display that you’re typing the number into won’t echo your keystrokes, so you have no idea if you’ve made a mistake.  (Plus you usually have to enter the stupid thing *twice*.)

It’s tempting to go to a 10-digit key (or even to give up on encryption entirely).

Try this instead — the next time you have to input your 26-digit key, type it first into Notepad (or Word or whatever).  Then use cut-and-paste (or copy-and-paste) to cut/copy the key and then paste it into the appropriate box on your display.

Okay, I’m sure an awful lot of you figured it out by yourselves — I’m embarrassed to say that I only started doing this a few months ago…

Geek Tip: Reboot! Unplug and Re-plug!

Monday, October 6th, 2008

You’re trying out your new scanning software — it’s working great.  But a few hours later, it suddenly stops working.  Now what?

Reboot.

Over the years, I’ve found that true Geeks do this without thinking.  They reboot before trying anything else.  And you know what?  If the software had been working properly earlier, rebooting will get it to work against 9 times out of 10.  Maybe 99 times out of 100.

You’d be surprised how many really smart people (even some very Geeky people) view rebooting as a last resort.  I can understand that — after all, if the software had been working properly, why should rebooting help?  And anyway, who wants to sit around for 5 minutes, waiting for Windows XP to do its thing? 

Trust me — start rebooting, and go play some Super Metroid while you’re waiting.  If you do this routinely, you will save hours of frustration in a year.  (Or rather, you’ll substitute hours of Super Metroid frustration for hours of computer frustration…)

The hardware equivalent is to unplug and re-plug.  If the device is battery-powered, then remove the battery and reinstall it.  (This is different from using the on/off switch — you should actually disconnect the device from its power source.)  Most computers and peripherals these days are actually “sleeping” rather than truly “off” after you use the on/off switch to shut down.  Unplugging and re-plugging is often the only way to get a device to reset.  (There was a printer at my parents’ house that hadn’t worked in months – an unplug/re-plug got it working again in less than a minute.)

And if rebooting/re-plugging doesn’t work?  Now you can start digging through the manual and Googling.

Good luck!

Geek Tip: Lower Case “L” or the Number “1″?

Tuesday, September 30th, 2008

It’s annoying – you get an automatically generated password with a character that could be either a lower case letter ”L” or the number “1″ (or an upper case letter “O” or the number “0″). 

Or you’re using your computer to write down some 20-digit software authenticity code, and once again you find that there’s an l/1 or O/0 ambiguity.

So you use a font like Courier — but that only works if the image is pretty large, and even then you might make a mistake now and then.

Here’s the answer:  Download and install ProFont:  http://www.tobias-jung.de/seekingprofont/

(For Windows XP users:  After you’ve downloaded the file, unzip it to your Desktop.  Go to Control Panel, click on the Fonts icon, Browse to the unzipped folder on your Desktop, find the ProFont file in the folder, Select, click OK, and you’re done.)

ProFont is a font that was designed for software coding.  The number “0″ has a diagonal line through the middle to distinguish it from the letter “O.”  And the lower-case “L” has rectangular serif on top, whereas the number “1″ has a diagonal serif.  The entire character set is clear and unambiguous even at small font sizes.

Finding ProFont has been the high point of my week!  Who knows what tomorrow will bring?

Connect the dots!

Thursday, July 17th, 2008

It turns out that when you print an image using a color laser printer, the printed image is likely to include a matrix of microscopic yellow dots that identify the printer’s serial number.

The ostensible purpose of these dots, which are invisible to the naked eye, is to help the Feds crack down on counterfeiters.  But even if you’re only a little paranoid, I’m sure you can think of a whole bunch of other ways the Feds might use the information…

Geek Tip: How to Organize a Hard Drive (and a Life)

Wednesday, June 25th, 2008

Rule 1:  Don’t buy anything.

Rule 2:  Don’t do anything dramatic.

Rule 3:  Start by organizing small stuff that annoys you on a daily basis.

Rule 4:  Don’t bother organizing stuff that you’re never going to need.  (You can keep it — but just leave it alone unless it’s in the way.)

Rule 5:  Instead of trying to pave over the Atlantic Ocean, aim to create islands of order in a sea of apparent chaos.

Rule 6:  Form follows function.

Rule 7:  If it ain’t broke, don’t fix it.  (Perhaps this should be Rule 1.)

Geek Tip: Partitioning Your Hard Drive

The only people who should partition their hard drives are the ones who can’t be talked out of it.

Geek Tip: Car Cell Phone Chargers Suck

Monday, June 23rd, 2008

You’re driving along, your cell phone dies.  No problem — you have one of those phone chargers that plugs into the cigarette lighter.  You hook it up and…

Nothing happens.

What they don’t tell you when you buy the g.d. thing is that a lot of car chargers don’t work if the cell phone’s battery is completely dead.

Geek tip:  Don’t waste your money buying a charger that plugs into your cigarette lighter.  Instead, get something called an “inverter,” which converts the output of your cigarette lighter socket into 120V AC.  When you need to charge your cell phone (laptop, pda, etc.), just plug the regular charger cord (the one you plug into a wall socket) into the inverter. 

You can find a decent one on the internet for $30-$40 bucks (and it will be good for *all* your chargeable gear, as well as any small corded electrical appliances you may want to use while the car is running).

Warning — when it’s plugged in, you should treat the inverter just like you would treat a live extension cord from a wall socket.

Also, you may find that the car has to be moving at a reasonable clip in order for the inverter to work at full capacity.

Tech Tips: The Dreaded Blinking Yellow Light

Monday, June 16th, 2008

My Dell Optiplex PC wouldn’t start, and the on/off button was blinking yellow.

It turns out that this was Blinky, the dreaded blinking yellow light (the power supply equivalent of Blooey, the dreaded Windows blue screen of death).

Of course, I didn’t have a current backup for the bricked computer, and the warranty had expired.

I found one quick fix on the internet: checking all of the USB ports to make sure that none of them had messed-up contacts that might be causing a short circuit. No such luck — my USB ports all looked fine.

I considered trying to install a replacement power supply into my PC, but I found a bunch of posts on the internet from people who had tried replacing the power supply and/or the motherboard (!) without success.

I decided, for the time being, to abandon the Brick, and to try to salvage my data by installing the Brick’s hard drive into another computer.  (What?  You don’t have a second computer on your desk?  What kind of Geek are you?)  Sad to say, the hard drive from the Brick was a SATA drive.  The second computer (an older model) only had IDE connectors.

No problem.  I went to the local build-it-yourself computer store and bought a hard drive enclosure (sometimes called a “shell”) for $50.  (You can undoubtedly find one for less, but I was in a hurry.)

I installed the Brick’s hard drive into the shell, and then plugged the shell into the second computer’s USB 2.0 port.  I was back in business in under 30 minutes.   If you look on the internet, you can find web pages explaining how to run email and other apps from an external drive.

I then ordered a used, off-lease computer at www.dfsdirectsales.com.  Assuming I read the spec sheets correctly, I should be able to cannibalize the Brick for stuff like RAM, etc., and install it into the new computer.  Total price, including shipping:  $278.00.  (If I had been more confident about being able to salvage parts from the Brick, I could have gotten out for $50+ less.)

So, all in all, Blinky only cost me about 90 minutes of downtime, and $328.  Plus, I get a new computer!  (Well, it’s new to *me*, anyway…)

Followup (March 19, 2011): It turns out that Dell Optiplex computers of a certain vintage have a known issue with their motherboard capacitors. If you’re a brave soul with a soldering gun, you can try replacing the capacitors — there are a couple of webpages out there that show you what you have to do. You can also try buying a replacement motherboard on eBay. As for me, the Brick is sitting in my garage, missing various components that were cannibalized for other systems.

News Flash: McCain Sucks at Computers

Saturday, June 14th, 2008

When asked question-du-jour ”Mac or PC?”, presumptive Republican nominee gave the Zen-like answer:

“Neither. I’m an illiterate.”

Watch:

 

McCain has some disinguished company.  Senator Larry “Toe Tapper” Craig, the Idaho Republican with the wide stance, has also told the press that he doesn’t know how to access the internet:

http://thinkprogress.org/2007/10/17/craig-falsely-claims-he-has-never-used-the-internet/

The sad part is that I *believe* McCain when he says he can’t use computers.  (Senator Craig, on the other hand…)
