  • Not all plastics are made equal. Two different 1.5 or 1.6 index plastics from different manufacturers will have different scratch resistance as well as different levels of aberration depending on how good their materials science is.

    All plastic is softer than glass, yes, which is why any plastic lens you get has a hardcoat to reduce scratching and if it is from a quality lab, a scratch/antireflective coat as well.

    If you’ve never had plastic lenses last very long, where you are sourcing them from is using inferior quality plastics with whichever lab partner they use. That or you a) leave them in a hot car and the heat damages them b) constantly leave them lens-face down on the table

    But I have had people with very stable prescriptions keep plastic lenses in good condition for 15-20 years in extreme cases.

    Laminated glass treatments may be used, but because they cause problems with the cutting machinery it is far more common in optical glass lenses to see chemical or heat treating. If these are done well, they can be quite resistant to shattering. This, however, really comes down to the individual skill of the person treating your lens and I’ve seen enough damaged eyes to be wary of them.

    Another reason many labs have moved away from mineral lenses entirely is that they shatter when being cut to shape for your glasses, posing greater risk to the one doing the edging and significantly greater cost to the lab. Depending on the complexity of prescription they may shatter up to 3 or 4 times before one cuts properly into shape.

    To add onto this, if you are using progressive glasses, you are certainly getting an inferior product as no lab I’m familiar with puts their new progressive designs into mineral. The majority only have designs from 15-20 years ago with terrible intermediate segments.










  • My current favourite controllers for the price is the 8bitdo Ultimate C2. They come with hall effect joysticks so no drift, theyre light and responsive, and they’re compatible with all consoles and operating systems that I am aware of. The 8bitdo ultimate is xbox-style joystick configuration, but the Pro2 by them is playstation style and to my understanding is of similar quality. Just make sure you get the hall effect variant to avoid potential future stick drift




  • I mean, for discharging your firearm in an enclosed space with tons of people around? Yeah, I definitely would consider the police at fault. Should the guy with the knife have been persued once it was revealed he was armed? Sure, I can accept that. But what I do not accept is that the police seem to, despite the absurd modern toolkit at their disposal, only have two tools they actually use: their taser and their gun.

    Why is it that seemingly anywhere else a knife-wielding assailant can be subdued without blood being drawn, but here it results in several people suffering life threatening injuries and one dead?


  • Kagi actually does an interesting implementation for their search summary and while not perfect, it is miles better than the alternatives in my experience. It uses a combination of anthropic’s claude for language processing as well as incorporates wolfram alpha for stuff that needs numerical accuracy. Compared to google AI or copilot I’ve been seeing good results.

    While it isn’t perfect at summarizing, I’ve found their implementation to be “good enough”, and it can summarize pieces near instantly, which I think is the place where it actually becomes useful. Humans may be better, but I dont have the money or time to pay a human to summarize pages for me to see if they’re going to be useful to delve further into.
