How to fix AutoCAD LT 2002 GEDIT 3 error

AutoCAD LT 2002 may suddenly crash with a Gedit 3 error (pictured below).

You get this after using AutoCAD for a while.
This is can be caused by drivers, or conflicts with certain software. Removing the software should also make the issue go away, if you can identify it.

And sometimes you just can't remove the software causing the problem. So here's a method worth a try.

First, you'll need to identify whether your AutoCAD LT 2002 has Service Pack 1 installed. From the AutoCAD command line enter "._vernum" (without quotes) and you should get something similar to _VERNUM = "K.0.44" (read only).

If it reads K.0.30 then you'll need to install Service Pack 1 first.

Next, proceed to install the patch to fix this error. Some sites refer to it as Service Pack 2.

Retry your AutoCAD LT 2002. The bug should go away now.

Good Luck.

Logitech MK220 impressions

The Logitech MK220 outside its packaging
The Logitech MK220 cordless keyboard + mouse combo is pretty good, honestly.

It's just too small for me. I'd much prefer a bigger keyboard and mouse. Right now my hands feel rather cramped using this pair. This is definitely a pair designed for smaller hands so if you're one of those this should be a mighty fine keyboard and mouse.

Keyboard battery compartment is on the left. Just slide down to open.
The mouse is the better of the pair. It's a bit on the small side so I wish it's a bit bigger but it's still usable. I just don't find it completely comfortable. There are much smaller (and less comfortable) mouse out there so you may or may not find the midway size comfortable to use. The scroll wheel cum middle button is rather hard to click though so you'd probably not like it much. If you don't use the middle click at all then all is dandy.

I find the keyboard is very very cramped so this is definitely made for smaller hands. Using this keyboard makes my fingers feel cramped almost immediately. I know some people find larger keyboard hard to use because their small hands mean it's hard to reach certain keys so this would make a good choice for them. There's no SysReq key though. At least I couldn't find any, so Linux users may want to avoid this one if you feel you need the key.

The keys also feel a bit flimsy during use. 

The USB receiver looks like most pen drives which is to say I wish it were smaller. For some reason I just get the feeling something or someone will accidentally fall onto the receiver on the back of my PC and break the dongle. They could've made it micro-sized to it doesn't stick out like a sore thumb. That's another consideration before you buy this.

Oh yeah. Batteries are included.

Well, that's about it.

How to install an old printer on Windows 7

Installing an old Samsung SRP-270 printer onto a Windows 7 setup was not something I thought I'd be doing.

But things turned out that way so here's how I got things up and running.

The problem

You'll probably get one of these problems when you try installing an old printer that doesn't have official Windows 7 driver software:
  • Windows says driver failed to install or something to that effect.
  • The driver installation program gave an error during installation (with or without compatibility mode enabled).
  • Windows says "The printer driver is not compatible with a policy enabled on your computer that blocks NT 4.0 drivers" when you try to add the printer as a shared network printer.
Attempts at installing SRP-270 attached to a Intel InBusiness Print Station fails
Just so happens I got all three while trying to figure this out.

The fix

So here's the simple fix for this. This is an abridged version taken from here.

  1. Run mmc from Run...
  2. Head to File then Add/Remove Snap-in...
  3. Add Group Policy Object Editor
  4. Expand Local computer policy->Computer configuration->Administrative Templates->Printers
  5. Look for "Disallow installation of printers using kernel-mode drivers" and disable it.
  6. Reboot so the policy takes effect.

Try installing your printer driver again; it should install without errors.

Decluttering the home PC

Okay so I did some decluttering of my PC. Here's the list of stuff I changed/replaced/added:

  1. Keyboard & mouse
  2. DVD burner
  3. Wireless repeater
  4. Speakers
I certainly dislike cables running all over the back of my desktop very much so I bought a Logitech keyboard & mouse combo to replace the old ones. My old Microsoft wireless mouse was a bit screwed up so that's an excuse to replace the keyboard at the same time.

Meet my new keyboard/mouse. They're a bit small for my liking though :-(

Coincidentally, my sister's very old keyboard was acting up so she gets my old Dell keyboard as a replacement. No sense wasting a perfectly working keyboard right?

My old DVD drive. Good riddance.
As for the DVD burner, Samsung really needs to make things that are more reliable. At this point the only thing Samsung I'd consider buying at all would be their SSD. Everything else is a no go. That includes their smartphones. Never liked Touchwiz.

These guys look nice but sounds a bit flat. Still, I rather not have a big subwoofer giving me headaches.
My Dell 5.1 speakers are a bit temperamental so I got myself a smaller Altec Lansing speaker to replace them. It turns out it was a waste of money for me to get the 5.1 speakers. I never had the space to properly utilise them anyway and the cable management is just painful.

Aztech dual band repeater. Keeps the Asus WiFi router off my table.
The final change is the addition of a Aztech WL580E wireless repeater. It's a signal repeater but... I'm using it for a different purpose: to connect to my desktop's LAN port. Rather than dragging a cable across the hall as I've been doing for years, I'm now making the wire wireless.

As to why I don't use a WiFi card... well, I do have one but Ubuntu doesn't load it up properly. Sometimes it works, sometimes it doesn't. I'd rather my connection be more reliable than that.

So next up I'll be replacing my Samsung monitor. It's flickering more and more frequently and that's driving me nuts... but that's for another day.

How to reset Canon Pixma MG2170 absorber counter

This is how to fix error E08 on the Canon Pixma MG2170 printer.

  1. Download the reset tool.
  2. With the printer power turned off, press and hold the Stop/Reset and the Power buttons at the same time.
  3. While still holding the Power button, press Stop/Reset 5 times. This turns on the printer's Service Mode.
  4. You'll want to make sure there's paper in your tray. Using the reset tool, click on the Set button in the Clear Ink Counter and Ink Absorber Counter sections. If it gives an error, select Main_Black then Set followed by Main_Color then Set for both sections. That worked for me.
  5. Click EEPROM under the print section near the top.
That should fix it. Just power off the printer then turn it back on again normally and you should be able to continue using your printer.
