  • There are two types of autofocus systems that cameras use, phase detect and contrast detect. Contrast detect is what all point and shoot style cameras (and early mirrorless interchangeable lens cameras) used where they identified contrast of vertical edges and used that to determine if an image was in focus, this is a slow process as the camera needs to figure out what direction to move the focus and check the image at multiple focus positions to compare until the camera determined it was in focus.

    DSLRs have a separate sensor up near the viewfinder that does phase detect autofocus, this is different in that it can determine how far the lens is from being in focus and go directly there which makes it significantly faster which was crucial in many professional applications.

    Eventually sensor manufacturers figured out how to integrate a version of phase detect into the pixels of the sensor itself. While these didn’t perform as accurately as the separate phase detect arrays in DSLRs, they had an extra trick where they were able to create a hybrid autofocus system that used the phase detect array to get close and then contrast detect to get accurate focus. It was only once this was implemented on mirrorless cameras that the advantages of SLR disappeared.


  • The end of DSLR cameras has been coming for some time. Manufacturers have been slowly phasing out their DSLR lens lineups over the past few years and I don’t think Canon or Nikon are making that many DSLRs at this point. At some point it won’t make sense for them to keep the lines around and the stock will dry up.

    It was clear around the time of the Sony A6000 that mirrorless would usurp the DSLR in the near future, that camera had already matched much of the performance of the high end cameras. Once the lens lineups were fleshed out more and the autofocus was applied to full frame there was little reason to buy into the older systems.




  • This drives me nuts, when an urgent issue comes up I value concise, accurate answers so we can quickly agree and actually do the work.

    We had an urgent issue recently and upper management wanted a plan for validating the fix. Rather than talking to the expert the manager one level down just sent an AI written suggestion without checking with anyone. After having checked with the correct person, I had to respond with “This is the MIL standard, we should follow this” while “ignoring” the manager’s email. Luckily I had the goodwill to get away with correcting people like that.





  • I’ve also been on Vivaldi since right around the start. I’d just wish they would fix their address bar suggestions to actually work. It isn’t great to start, and then decides to completely break every few months and do stuff like when I type “you” to go to youtube it insists on autofilling to a specific video I watched months ago. The only fix I’ve found is to nuke the profile and start over.

    I’ve switched to Zen on my computer a couple months ago exclusively because of that issue.






  • The further you get from the front lines the less you have a grasp on day to day operations, especially when the job changes. Double that for leaders that never held technical positions, and come from other areas that guide their view on things.

    Then you have the power imbalance with a hierarchy, if someone is responsible for your job you are more likely to just say “yes” to bad ideas than push back on them. Even when a manager is receptive to feedback that doesn’t mean the ICs are going to give the feedback, or they get demoralized when their ideas aren’t taken for valid reasons.

    Most websites allow you to change your email address, get one from somewhere else and slowly start changing them over until there are no more you can move. If you get your own domain you can ensure you are never trapped in any particular email provider ever again, though you will be playing about $50/year for a domain and email service. I have maybe a handful of things that still use Gmail.
