Participating in the logo discussion for the LinuxReality podcast over the past couple of weeks got me using Inkscape again. (BTW, Chess ended up going with one of the puzzle piece logos I submitted - check out the site banner over there. It was great fun discussing and coming up with that logo.)

Inkscape really is a full featured vector-based editing program. Being vector based, it lets you do a lot of things that you just can’t do in a bitmap editor like Photoshop, The GIMP or Paintshop Pro. One of the things I’ve been playing with since trying to come up with logo ideas is using hand doodles, my scanner, and Inkscape to experiment and have some fun. Here I’ll illustrate the basic process I’ve been monkeying around with.

First I scan the post-it note into bitmap form (in my case .jpg):


I then import the jpg file into Inkscape. Once it’s in there I select it and then choose Path->Trace Bitmap. This gives a dialog with 5 different methods of creating a vector object from a bitmap. In this case I used the ‘Image Brightness’ method and got a fairly faithful vector representation of the original sketch. It creates a path of nodes making up the shape of my sketch.

Then I selected the resulting path object and used the Simplify Tool (Ctrl-L) which well …er… simplifies it. It rounds corners and makes it slightly more organic looking. You can repeatedly apply Ctrl-L and watch the effects. The image below shows the effect of only one Simplify application.

After simplifying I created a rectangle matching the background colour of my blog and placed it under the simplified path object.


Of course there are a ton of other neat things you can do with Inkscape (and a ton of better sketches you could work with) but it does illustrate some of the flexibility and fun of using a vector based application like Inkscape. And it’s currently available for both Linux and Windows (with a native Mac version coming very soon apparently as well), so everyone can join in the fun.

For the last couple of days I’ve been having a problem with my ADSL modem. Maybe somebody out there can give me some tips on fixing it. Here is a description of the symptoms:

I left the modem powered off all day yesterday. When I got home I turned on the modem and the PC and booted up. Everything works fine - for about 1-2 hours. Upon turning on the modem the ADSL light blinks slowly, then quickly and then stays on steady once it has synched. This is the normal behaviour.

The problem is that after about 1 or 2 hours the modem starts to lose sync. It appears to lose the connection and then the ADSL light goes through it’s slow-blink, fast-blink routine and reconnects. It then seems to achieve connectivity for about 2 minutes and then loses it again and reconnects. It repeats this on and off every couple of minutes. Occasionally it isn’t able to reconnect at all unless I power down and then power up the modem.

I’ve tried powering off the modem for a minute or so and reconnecting but this only serves to give me about 5 minutes of connection time before it goes into the 2 minute intermittent connectivity behaviour again.

Very frustrating. I’ve not had any other problems with this modem.

The only other clue might be the power outage we had a couple of days back. Could this have damaged the modem somehow?

Any help would be very much appreciated. I’m afraid to call my ISP support line since I think as soon as I tell them I’m running Linux they’ll tell me they don’t support it and won’t help me out.

It was a typically ‘not quite as lazy as I’d like’ Sunday morning. My daughter on the bed, watching TV and waiting for Daddy to get showered-up so we could be on our way to Grandma’s. She’s watching Backyardigans or something similar. Suddenly, she calls out “Daddy, something’s wrong with the TV…”. I peek my head into the room and ask her what the problem is. She says, ‘My show keeps stopping and then … see? There it goes again Daddy!’.

What my daughter was experiencing was a broadcast TV commercial.

Normally she’s always watching TreehouseTV, CBC or PBS. None of the three show any commercials in the middle of their shows and even then, only network promotional commercials between programs (or whatever it is you call it when network advertise their own programming). In other words, my daughter hasn’t seen any (or at least very very few) ‘Barbie’, ‘Polly Pocket’, ‘My Little Pony’, or thankfully ‘Bratz’ commercials in her first 4.5 years of life. That particular morning we had it tuned to CBS or NBC or some such. I explained that it was a commercial, that I thought it was annoying and she’d be better off if I switched the channel. She offered no argument. ;)

One benefit of this has been the fact that we can routinely peruse the toy aisles at the local department store without cries of “I want this” or “Please please please get me that”. Sure, it won’t last much longer, but I’m enjoying it while I can.

Of course my daughter already has at least a dozen Barbies (mostly gifts or fruits of my mother-in-law’s penchant for Saturday morning garage sales) and she’s quite familiar with all the big franchised products when we pass them in the aisle. But there isn’t that intense desire for specific toys yet. If there is a desire, it is not yet strong enough to warrant whining about it - thankfully.

I had simply forgotten about the intensely focused marketing that happens on regular broadcast TV during children’s programming. So long ago are the days when I drooled over Smash-Up-Derby, Stretch Armstrong or the latest and greatest Tyco-TRX racetrack setup (I was the proud owner of a Super-Duper Double Looper no less!).

I look back at those days fondly, but I have no sense (nostalgic or otherwise) that my daughter is missing anything. There’s still plenty of time for her to be coaxed into buying and begging the latest and greatest things by the great advertising machine that is modern media.

For now, she is not yet assimilated. And that, is a truly wonderful thing.

Yikes! Power went out tonight at 7:50pm in the middle of little one’s bedtime story. After about an hour of ‘fun with flashlights’ we decide to get her over to my parents (10 minutes away and fully powered). Getting back here at 10:15pm I thought for sure the problem would be fixed. I arrive back to find total and complete darkness.

Suddenly I realize that a cold morning shower is NOT the top concern. My mind scatters as I try to comprehend the fact that I won’t be able to make my NaBloPoMo post for today!!! Am I really going to find myself in the same boat as OmegaMom?? Is this the end for our unlikely hero? (me).

I set my watch alarm for 23:45. Fifteen minutes should be plenty of time to save my blogging soul should they get the problem fixed in time. I resign myself to sleep and was just dozing off when, at 10:52 technology springs back to life all around me. Yay!!

Running around to turn off all the lights left on (it isn’t going to be ME to blame for frying the recently fixed system with a power surge) I finally kick the kettle to life and sit myself in front of the keyboard.

Disaster avoided. And perhaps more importantly, no worry about searching for a posting topic! :)

Good night.

In this age of hyperactive personal productivity, telecommuting, and the always-on 24/7 work week, there is a lot of talk about stress and how to deal with it.

Instead of giving you the latest Feng Shui-43 Folder-Taoist monk idealogy (you can get that just about *anywhere* on the net these days!) I thought it’d be interesting to give you an alternate view of stress.

From where I come from (an engineering background), stress is a force applied over an area. It’s more popular nickname might be ‘pressure’. When you fill up your tire with air you measure the pressure in ‘psi’. That’s ‘pounds per square inch’ - a force distributed over an area. Pretty basic huh?

What’s better is when you realize how fundamental the idea of stress (or pressure) really is:

Stress = Force / Area

Ever walk in deep snow? If you’ve got your normal winter boots on, you’ll quickly find yourself sinking in up to your knees . How is it that when you put on a pair of snow shoes you can walk on top of that snow? Stress baby! More precisely the reduction of it. The force (your body weight) hasn’t changed, but the area you spread that force over has increased. So if stress is a force divided by an area, by increasing the area you’re reducing the stress! Snow of course can only take so much stress before it compresses/collapses/fails, so by wearing big wide snow shoes you increase the area, reduce the stress and don’t fail or crush the snow (as much as you normally would).

How about a more simple, involving example:

Step 1: Take a nice sharp pencil.

Step 2: Jab it at your arm.

Step 3: Remove said pencil - swear like a trucker - and mop up any blood.

Step 4: Next, take the blunt end of a wooden spoon handle.

Step 5: Jab it at your arm.

Step 6: Smile and notice that you’re not swearing like a trucker, nor mopping up blood.

Why is it that the sharp pencil hurts so much while the blunt wooden spoon handle does not?

Assuming you applied the same jabbing force in each case, the contact area of the pencil is much much smaller than that of the wooden spoon handle and hence the stress applied by the pencil is much much higher than that applied by the blunt spoon handle. The larger the contact area, the lower the stress.

This basic concept of stress is put to use all around us everyday. Building footings are designed with this concept of stress at their core (think concrete snow-shoes people!). Bridges, buildings, cars, airplanes, machinery and a multitude of other things rely on the basic principle of stress in much of their design.

So when you think of stress, don’t just think of Taoist monks and aromatherapy. Think of blood, pencils and snow-shoes as well. :)

P.S. Wow. I actually put an equation into a blog post. I’ve really got to get out more. ;)

I consider myself a fairly ‘with it’ kinda guy. I think I’m fairly adept at staying in tune with what’s going on with those several years my junior. Sometimes it gets a bit wacky (for instance I love to throw the odd urban slang term into conversations just to surprise people… it’s the shiznit. Da bomb so to speak.).

Of course if you met me you’d quickly realize I’m about as far away from urban street culture as they come. But being aware of all stuff youthful (and not necessarily engaging in it) has always been subliminally high on my priority list. I think it stems from a fear of growing old, or perhaps more accurately a fear of becoming a ‘curmudgeon’.

But alas, at times I find myself inexorably drawn down that path. In the recent past I have noticed my disdain for retail clerks who don’t know what to do when the price for something is $8.34 and I hand them a 10-er along with 35 cents. I’ve been told repeatedly that I must have mistaken the price, and have to explain that I do it so I can get back a Toonie (Canuck-speak for our two-dollar coin) and the one cent is my gift to them :) .

In the last few months however my focus has shifted to grammar and spelling skills. I’m a fan of Digg.com. I find some of the stories interesting and many times I find the comments even more entertaining. But I am absolutely astonished at the frequency of incorrect spelling and grammar on that site. And it’s not the only one.

Okay. I can forgive to’s for too’s in blog postings till the cow’s come home. The ubiquitous ‘teh’ for ‘the’ almost goes unnoticed. But “they’re/their/there” mix-ups are really starting to grate on my nerves. And reading about how somebody is about to “loose the game” get’s me grinding my teeth (something I haven’t done since the age of seven!).

I could go on and on. But I won’t because I’m hoping that you dear reader, know exactly what I’m talking about. Now am I immune to it? Likely not. You will find the odd mistake in my posts. I don’t use spell checking anywhere (I feel it’s a cop-out) and when I’m unsure about a word’s spelling, a quick Google search with the “define:” keyword usually comes to the rescue, not only giving me a good chance at confirming a spelling, but also enlightening me to some useful synonyms as well.

Put bluntly, I am NOT a grammar expert. I throw sentences together like a monkey throws poo, but at least I *try* to have aim. A lot of the stuff I read looks like the person wasn’t even trying at all. Where is the pride in your work people? Whether it’s a comment on Digg or a blog post, don’t for a minute think that it will get missed. In this little sphere of text-based technology your writing skills can define you, or defame you. Please people, just take 15 seconds to read over what you type before hitting that ‘submit button’.

Now doesn’t this read like the ranting of a closet curmudgeon? Next thing you know I’ll be prefacing every post with “Back in the day…..”. Hmmph.

Word to your mutha.

Despite my utter happiness at running Linux at home, there are still a couple of windows-only apps that I sometimes need to run. They’re work related and as much as I try to avoid it, there are times when I need to run them. Right now I am forced to reboot into XP to use those apps every once in a blue moon. I think I may have found a better solution (other than not running them at all).

Today at work (on my XP-Pro machine) I took a stab at downloading the free VMWare Player and also downloaded an Ubuntu Dapper ‘virtual appliance’ image (there are lots of free images on the site). Within minutes of finishing the downloads I was running Linux inside the player and suffice it to say I was quite impressed!

Doing a little more searching I came across a link to a page describing how to get XP running on a virtual machine on a Linux box. While I didn’t have time to do a heck of a lot of reading up on it (I *was* at work after all) it seems that the open-source QEMU virtual machine can do it and by setting up a Samba share you can even facilitate the movement of files back and forth into and out of the virtual session.

Now I know even less about Samba than I do about virtual machines, so when I do get the chance to set it up here at home it may take a while to get it into a usable state for me. But as always (and many times to my detriment), I’m up to the challenge.

Yet another technical challenge awaits. Does it ever end? :)

After more than 6 years of complaining, why is it that people in my office still send me frickin’ chain letter emails. Does this mean harsh email replies in red, 48 point bold font demanding that they "never send me this sh*# again" don’t actually work? I guess so.

Anybody got any better solutions?

PS - DON’T forward this info to 10 friends and you’ll have great luck!!

If you’re a father…no wait.. a parent… no… actually anybody at all who wants to read a powerful blog post - then read this one.


A week or so ago I posted about using Inkscape to submit some logo ideas for the LinuxReality podcast. I’ve been noodling around with it over the last week or so and I’m mesmorized at how easy it is to do really neat looking things with it.

One of the things I submitted involved a guy leaning against something. I scratched out an idea at work on a yellow sticky note to store the idea. When I got home it was dead easy to scan it in and import the bitmap image into Inkscape where I easily traced it and added some gradients and outlines. It’s by no means perfect but it’s dead easy.

Incidentally the pencil drawing packs much more character than the vector art does don’t you think?
