    My employer uses Akamai as a CDN (and security) provider for their websites. Akamai has an optional tool called Image and Video Manager that, in a nutshell, optimizes images for better site performance.

    Basically you put a high quality image on your website, and when Akamai retrieves it the first time it optimizes its color palette, compression, size, and format for multiple devices. Each derivative image is cached by Akamai for 30 days at a minimum.

    So while you may put a 1000x1000 JPG with a quality of 95%, an Android user may be served a 200x200 image with 80% quality, and it may be a WEBP or PNG format instead of JPG. Exactly which derivative image is served is based on criteria like the web browser being used, the viewport size, etc.


  • Not exactly 911, but somewhat similar. A few years ago my wife & I were in a rental SUV while on vacation. It was a fairly new car with only something like 2000 miles on it. We were in the third lane of a 4 lane highway when a drunk driver hit us from behind with almost no warning. It caused our car to spin 360 degrees across 3 lanes before coming to a stop in the breakdown lane.

    Within about 5 seconds of the car coming to a stop we heard a voice asking if we’d been in an accident and were we ok. It turns out the rental car had one of those OnStar types of services. We were so pumped full of adrenaline that it was all just a blur as we tried to remember what highway we were on, near what exit, etc. We were so panicked… Luckily a state trooper on a routine patrol stopped maybe a minute later so we didn’t have to keep trying to figure out how to tell the OnStar person where we were.



  • IT professional for 20 years. C/C++ developer for 10 years prior to that.

    My first job out of college was mostly luck. I took a job doing tech support but after a couple of years was able to transition into development work.

    Virtually every job since that first one has been thanks to connections I made among coworkers. I got my current job because I knew two employees here. One of them was a co-founder of the company, and somebody I’ve known since the 1990’s and worked with at 3 other companies prior to this.











  • My wife has a dog boarding business, and a good number of the dogs have air tags attached to their collars. Most of the owners geofence around our home/boarding facility so that we don’t get constantly nagged by them. But when we drive one of these dogs somewhere (usually to walk/exercise them on a hiking trail etc) we often get alerts on our iPhones about unrecognized air tags that have been nearby us for a prolonged time. It will include a map showing our track and where/when the air tag was detected each time along the way.

    So while I don’t use them personally I’ve seen that they do indeed work quite well. Maybe next time I travel I’ll get one for my luggage.
