Most of you younger folks won’t have to worry about this for a few years, but…
… it’s a reality of life that as you get older, your eyes don’t work as well as they used to. Case in point: when you’re reading those websites with that minuscule font size, you have to grab your cheater glasses to see what’s going on. Unfortunately, not all website developers are nice enough to use a #16 Deja Vu Sans font for us older folks.
In cases like that, there are options. In Firefox, my browser of choice, I can go to Menu: Edit –> Preferences –> Content –> Fonts & Colors – Advanced button and set my font styles and sizes the way I want them to be. This is how I used to do this for many, many years now. However, last night, while poking and prodding FF a bit here and there, I found a neat way to set fonts that don’t affect every website.
The problem with forcing font sizes and types globally in FF is that many web pages, this one right here on wordpress.com, for example, will not display certain characters properly. A while back WordPress, and Photobucket, too, started using these cute little html graphics to identify buttons and menu items. Well, if you’re forcing Deja Vu Sans in FF, those little images show up as weird Greek-looking icons that make no sense whatsoever in relation to their actual assigned purpose. That was beginning to annoy me, particularly at Photobucket, so I stopped forcing fonts and sizes in FF, which allowed the browser to display the websites as they were designed.
Great! Just one problem. Now we’re back to the little font sizes again and the need for me to scramble around in the semi-darkness in the cave here feeling around for my cheater specs. They’re only 1x, but nice to have when you want a little boost in acuity.😉
Hmm… what to do?
Well, anyone who has used Firefox for any length of time knows, or should know, that you can zoom text and images or just text alone on any web page just by using the combination of CTRL and the + or – keys on the keyboard. You can also do it by holding CTRL while rolling your mousewheel, if you happen to have one. Cool, huh? Here’s my problem, though. I visit many different websites every day. I don’t want to have to be zoom-zooming every time I go there. That’s why I had the global settings set as I did before.
Now for the OH, WOW! moment from the You Learn Something New Everyday department. I found that FF will actually remember zoom setting for individual pages even after you close the browser, log off your system, and climb into bed with hopes of pleasant dreams involving interesting book discussions on a desert island somewhere in a grass hut with a half-shell of coconut wine and this young lady by your side…
Er… but I digress.
Anyway, it’s very cool that FF remembers the zoom settings for individual pages. I haven’t tested it, but my guess is that if you toss your cookies or clear out your site preferences using the Clear Recent History tool, you’ll probably lose all those individual zoom settings and have to set them all over again as you visit the sites. Still, it’s COOL. I’m glad I found out how to do this. Now I don’t have to force fonts and sizes in FF and all the little weird characters makes sense again.
Ain’t technology wonderful?!

Well, I don’t usually jump for joy about Firefox extensions; however, in this case…
For quite some time now, I’ve experienced herky-jerky scrolling and excessive CPU hogging in Firefox. It’s been very annoying. Some versions seem to fix it, then in a few weeks, when there’s another update, the jerkiness comes back. This happens to my Firefox in Slackware Linux, but I’ve experienced it in other distributions and in MS Windows, also. I’ve tweaked till I was nearly blind. I’ve searched for remedies all over the Internet. I’ve done the usual suggested “Safe Mode” operations and disabling selected extensions here and there to try to get FF to behave. Nothing has worked, until tonight…
I decided to install an extension that was recommended to me by someone quite some time ago. I apologize to that person here and now for not believing that this extension would resolve the issue. I had enough extensions. I didn’t really want another one. Well, a couple weeks ago I lightened the extension/addon load on my FF down to about 1/3 of what it was; just some Profile house-cleaning. It needed to be done. So now I have my leaner meaner FF to work with here. I decided to install this smooth scrolling extension and see if it would actually work as advertised.
The extension is called SmoothWheel by Avi Halachmi. Right out of the box, it performed miracles on my FF. I didn’t even have to adjust the pre-set preferences. I mean this thing works! I can pull up a Bing Image search page for “cleavage” now and FF will scroll just as smoothly as all the curves on that search result page. It’s wonderful! I love my FF again. Thank you Avi! By the way, the $5 donation he asks for is well-worth it.
So there, you have it…

Ever been typing along somewhere and have your cursor jump across the page because your thumb hit the touchpad on your laptop accidentally?
Well, on some of those high priced commercial operating systems like Windows or MacOS there might actually be a setting or a keyboard shortcut that disables your touchpad. Us Slackware users are made of stronger stuff than most. We don’t want no silly buttons and keyboard shortcuts. We want scripts and command line stuff, right? We like to do things down at the nitty-gritty level of computing.
So, with that in mind, if you’re running Slackware/KDE, you can make yourself a nice little script that will disable your laptop’s touchpad and you’ll never have to cuss again when that cursor goes zooming across the screen while you’re typing that flaming post on USENET to that know-it-all Ubuntu dev.
Here’s what you do…
First check to see if you have a /home/<username>/.kde/env directory. If you don’t, create it:
you@your_system ~:$ cd .kde
you@your_system ~:$ mkdir env
You can also do this graphically, if you prefer, but we know you hardcore Slackers don’t do things graphically now, do you?😉
Anyway, once you’ve determined that you have the directory or have created one, you can now create the simple little script to place in there that will KILL that annoying touchpad.
Using vi, vim, or whatever editor you like, create this small file:
Save the file as “myenv.sh” in your /home/username/.kde/env directory. Make sure it is executable:
you@your_system ~:$ chmod 755 myenv.sh
Log out of your current KDE session and log back in. The touchpad from HELL is now as dead as weird uncle Bob’s hairpiece. WOO-HOO!
For those of you who occasionally use your laptop sans an external mouse, you can always revive the touchpad by changing the permissions on the myenv.sh file or just renaming it to myenv.inop. Since “inop” is an extension that the operating system does not recognize, it just ignores it. I’ve used “inop” to kill executables since way back in my Windoze daze. It works fine.
Anywho, I hope this little trick will make your Slackware/KDE computering that much more enjoyable. Oh, and I cannot take credit for this at all. A member of the kde.org forums called google01103 posted this tip in a thread over there about disabling that pesky touchpad. Credit where credit is due. That’s my motto.

Well, this article is just what you need.
Recently, over at Scot’s Newsletter Forums, we were discussing email encryption options and methods. It’s a fun thread. Give it a looksee. There is some good info and some useful links to be had. For me, this is the culmination of all the recent stories regarding NSA and FBI email and Internet snooping spurred by the revelations of ex-NSA contractor, and current guest of Mr. Putin, Edward Snowden.
People should be more conscious of their privacy, I think. You’d be amazed how many people think that email is private. I asked five of my family and friends about this in the past couple days. Everyone of them thought email was at least as private as 1st class USPS mail (snail mail). None of these folks were technical types. They were just aunts, truck drivers, etc… everyday people. Sadly, I’d bet that many techies out there are just a confident of the privacy of their emails.
With all this in mind, I’m here today to enlighten you just a bit about email privacy (or lack thereof) and simple, yet very secure, methods you can use to ensure that what you send to grandma will only be read by grandma. We’re going to talk a bit about email encryption using OpenPGP. You can do this in GNU/Linux, MS Windows, or MacOS. Encryption works everywhere for the most part. You just need a couple tools to make it happen.
My focus is on the Thunderbird email client using the Enigmail extension in GNU/Linux, Slackware to be specific. However, encrypting of emails and attachments is not difficult in any operating system. You just may have to use different means and applications to achieve it. Enigmail uses a protocol called OpenPGP. It is a very secure means of encrypting email and other documents using the Pretty Good Privacy data encryption method.
Security In-a-Box has created an excellent illustrated tutorial for setting up Enigmail in Thunderbird. I wouldn’t even attempt to top that one. Click on the hyperlink and learn very quickly and easily what you need to do to set this all up for yourself. In a matter of a few minutes, you can have your T-bird set up and capable of sending/receiving encrypted emails to your family, friends, workmates, etc.
For you MS Windows folks, there are also options. Windows Mail has a short FAQ regarding digitally signing and encrypting emails. It’s concise but informative. If you want to utilize OpenPGP in MS Windows, you can also do that thanks to the German government for creating an app called Gpg4win that allows you to set up and use OpenPGP in MS Windows just as you would in Linux.
There are quite a few good websites that explain email encryption, its methods, and the tools necessary to perform this feat. Here are a few to help you understand how this stuff works:
- Why Should You Encrypt Your Email – About.com
- How to Encrypt Your Email – PCWorld
- How Do I Send Encrypted Email – Ask Leo
It might seem complicated, and the encryption part is pretty heavy stuff mathematically speaking; however, to actually utilize the tools available to encrypt your email and documents is not at all complicated. You drive your car yet you have no clue how the internal combustion engine works, right? Well, there you go. You don’t have to be Einstein to encrypt your emails. C’mon! Even grandma is doing it. Give it a try. Encryption can be FUN! And remember…
Privacy is a right.
Security is YOUR responsibility.
Trust no one. Encrypt everything.
Have some fun with it. You might even learn a thing or two.

Wow! What a refreshing idea; fix something rather than toss it in a landfill and purchase another. Who’d a-thunk it? Well, let me brief you younger folks on a bit of history…
Back in the Dark Ages… oh, say 25 years ago or so… we used to actually fix things. Yup. That’s right. When your dad’s Sony Walkman or mom’s Singer sewing machine stopped working for some reason, they’d take it into a shop where a repair person*, with actual knowledge of the device and real tools, would sit at a work bench and troubleshoot and fix the issue for them. Awesome, huh? Then, dad and mom would pay a small price (compared to the price of a replacement) and take their Walkman or sewing machine home for many more years of use and enjoyment.
Now, why did such a remarkably sensible solution to broken items go the way of the T-Rex? Well, it’s simple. Greed. Yup. That’s right. You youngsters may have heard me gripe about greed before. It’s an all-pervasive sickness in this world at the moment. I’m not here to bitch today, though. I’m here to tell you about a really cool website that might appeal to you tech nerds and geeks out there.
iFixit – it’s sorta’ like a Wikipedia for fixing stuff. Between this site and another old favorite of mine, How Stuff Works, you should be able to fix just about anything in your home, as long as you have the skills and can get the parts needed to do the fix. Fixing things yourself is rewarding. You feel you accomplished something. Wouldn’t it be cool to be able to fix that favorite old laptop of yours with the jammed up keyboard? You can do it. It could actually be rocket science, but hey… rockets aren’t that complicated. Really!😉
Well, next time you play with your little iThing, think about the 11 year old Chinese girl who works 16 hour shifts in the factory that makes that thing. Think about the entire countrysides laid waste by the mining of rare earths to make that thing work. Think about all your friends and neighbors who would love a job in a factory that makes stuff instead of some dead-end job in a cubicle farm of some call center. When your iThing breaks, FIX IT! That’ll piss Apple off, huh? Heh-heh…

Being able to have common profiles for my Mozilla products across operating systems on my main computer has been a dream for a few years now.
I tried this a few years ago between Slackware and my then secondary OS, Debian (stable). The way I had it set up then worked well until the day that Debian dropped FF and TB from their repos and started using their own IceCritters. Another problem I had back then was that Debian’s Mozilla apps were usually quite a bit older versions than the ones in Slackware. If the versions get too disparate, as they eventually did between Slack and Debian, the common profiles no longer function properly.
Later on, when I adopted Arch Linux as my secondary OS, I tried to run common profiles again. I had forgotten my lesson about needing similar versions of the Mozilla apps for the common profiles to work. Arch is much faster at getting newest versions into their repos than Slackware, so once again I had this version disparity issue. Since Mozilla’s recent change to the update-as-often-as-you-change-underwear schedule, I’ve learned to blacklist Mozila apps in Arch so they don’t get updated. Once Slackware puts out an update (I manualy download and install from current) for the Mozilla applications (Firefox, Thunderbird, Seamonkey), I allow the Arch update to go through.
Now that I have my Slack and Arch Moz versions the same or very similar, the common profiles should work. Below is a look at how I did it on my system. It will, of course, be different on yours, but the principles are about the same.
First, I used a common partition on a separate internal hard drive for my common profiles directory.
This partition automounts within my /home/<user> directory at boot up. You could theoretically use a thumb drive for this, if you wanted to. You’d just have to make sure that it automounts with the proper permissions at boot time.
Next, I copied the firefox and seamonkey directories from my Slackware (main OS) /home/vtel57/.mozilla directory into my newly created /home/vtel57/vtel57_common/common_mozilla directory. I also copied the contents of the .thunderbird directory into a directory called thunderbird also in /home/vtel5/vtel57_common/common_mozilla. You can perform these operations from the command line or in your GUI file manager app, as you prefer.
Now, in the /home/vtel57/.mozilla directory, I renamed the old firefox and seamonkey profiles to inoperative. The old profiles had some random <number/letter>.default as their name. I just added “inop” to the end of that to deactivate them. I did the same with the /home/vtel57/.thunderbird profile. This will prevent the apps from trying to use these old versions.
vtel57_Slackware~/.mozilla/firefox:$ mv 3mvew7qq.default 3mvew7qq.default_inop
Back in the new common directory shown above, I renamed the <number/letter>.default profiles to names that made more sense to me: ff_profile.default, tb_profile.default, and sm_profile.default.
Once I did all of the above, I needed to edit the profile.ini in each original application directory (/home/vtel57/.mozilla/firebird and seamonkey, /home/vtel57/.thunderbird) to point to the newly created common profiles. You can open your favorite gui or command line editor and make these changes to each profile.ini file. Here is my profile.ini for Firefox, for example:
*change the items in red to the ones in green
So now, whenever I fire up firefox, seamonkey, or thunderbird in either Slackware or Arch, they will be running off the same profiles; meaning all data, preferences, etc. are synch’d. Ain’t it great!?
I’m sure there are easier ways to do this, but this is how I managed it. You can experiment to find what works best for you on your systems.
