Over at my company YouTube channel I've posted a few light board videos, mostly test runs through with short ~3min videos.

I've tried a few techniques that seem to have worked well and thought I would share.

First, clean the glass. Both sides. Speckles of dust become beacons!

Second, no light on the camera side of the glass. I installed blackout curtains.

Third, camera settings. I use F2.8, 1/100 shutter, ISO 320, on a Sony RX10 IV. This means the camera is focused on a very shallow depth.

Fourth, the post production. I use kdenlive and audacity. I first run the audio through a noise-reduction filter. I then crop the edges. I then use a Bezier-curve to slam the black level down (so everything close to black becomes absolute black). I then flip (mirror) so you can (almost!) read my scribbles. I then use a chroma-key overlay and pick up the whitish-green marker and replace it with a neon green (see below video).

To add a bit of pizzaz, I sometimes overlay in objects or colours as well (you'll see that here for example).

Getting the lights and microphone setup was a lot of trial and error, I think i have it relatively dialed-in now.

For those who wish to follow the journey, please feel to subscribe to the YouTube channel, and of course, the company blog where I will promote them and add some descriptive text, some what like here.

Let me know if you have suggestions for content or how to improve the videos!

I don't know what surprises me more: there is a 2-hour 4K video of snow removal? That 1.1M people have viewed it? That @ 1:47:39 we happen upon a snow pile so high that they tunneled through it for pedestrians?

Anyway you look at it, its better than most reality tv out there.

So today I headed to home depot. In the decking aisle I obtained a 42x36" piece of glass designed to be a railing. I purchased a pair of 2x4" w/ a groove cut as well.

I then bodged these together, somewhat like below. I took a LED light strip and wrapped it around the glass (facing in).

The results, well this is a first test video w/o cleaning it or tuning the camera. But i think it shows promise. What do you think?

 

 

 

The CBC did a good job of explaining the phases and restrictions. In a nutshell, as of December 19, 2019, Telco in Canada must either block invalid caller ID numbers (e.g. ones that are not dialable), or, provide the user some filtering options.

Now, this will be unlikely to make much difference. The spammers just spoof the caller ID to be a real number to get around this. What we really need is BCP38, a tool from the IP world where I accept a packet from your only if the source IP is one I would route back to you.

There is another phase coming, a sort of verification of networks approach, somewhat along the lines of BCP38, that comes online by Sept 30, 2020. Will that stop them? No. The only thing that will stop the scammers is destroying the risk:reward ratio. We must increase their risk (getting arrested, fined, going to jail, etc), and lower their reward (less people fall for the scam).

On the first, this is an enforcement issue. On the second, its an education issue as much as a technology one. If you each explain to a few friends that "no one takes payment in Apple iTunes cards" and some of the other common features of the scam, and if those friends explain to a few, this inoculates the population. Herd immunity.

I suppose we could also introduce a system where every phone call was a callback: you call me, my phone sees your caller ID, and calls you back. This would guarantee the system, and make the enforcement much simpler (but still not perfect).

As for a better sort of punishment for those caught, how about we develop a method to surgically implant taste-buds in their sphincter's? Who's with me on that!

Let me introduce you to Legal Linda. I met her on a lawyers site. Our relationship is either purely professional, or non-existent, depending on how you view it.

Legal Linda assures me that she is artificially intelligent (no word on the certified Turing test results). But she also reminds me that I don't have an attorney-client privilege with her.

Now, I had not considered I would... But now I am wondering... how long before me and Internet-enabled-Chatty-Kathy could be considered to be in a attorney-client relationship? Would her algorithm have to pass the bar exam? If it did, could it be licensed into all sorts of products I use (gmail etc) to render them subpoena-proof?
