  • I have 16 inch framework. I bought it fairly stripped down, only getting the parts I really needed for basic function as a laptop. I then bought additional parts as I had money for them and slotted them in. Made it a much more affordable purchase over all.

    And… then I spilled water on the keyboard. Shut it down, pulled it apart a little, dried next to a fan for a bit. Water hadn’t gotten past the keyboard luckily, but the keyboard was only partly functional. I just got a new keyboard module, put it in my self, good as new. No sending out the whole computer, no getting told by the rep that the whole machine was broken and I had to buy a new one.

    Payed for its self immediately that day as far as I’m concerned.






  • Probably not with SARH, multiple emitter sources would just complicate the job of the detector on the missile. Like I’m sure it could be made to work with a bit of compensation, but it would add cost and complexity to the seeker on the missile, which sort of defeats the point of such a system being cheap and easy to build. There’s also the Possibility that the returns would be too diffuse for a detector on the missile to track beyond that 20km range, so having additional sets beyond that range wouldn’t help. Probably easier and cheaper just increase the range of a single radar. Just putting the whole set on a really big missile and making it an active radar homing system might make sense with an array of sets providing warning and an initial vector, and the missile guiding it’s self in, but again, now your missile is the cost of at least one set per launch.

    Not sure what limits the range on this set, but they mention a wave guide improving it, which makes me think it’s just a power limitation on the emitter or limited sensitivity on the receiver.



  • Nah, that missile was visual tracking. Not radar guided. Also, way too small to intercept anything going high and fast which is generally what the patriot is for. Intercepting an aircraft requires a really powerful motor to give it enough speed and altitude to catch a plane.

    This radar could maybe be used with a semi active radar guided missile, where the ground radar lights up the target and the missile just has a detector that homes in on that, which is what early patriots used. But it’s only got a 20km range which isn’t really enough for an anti aircraft system, unless all you’re worried about is something slow and low to the ground like a helicopter or cesna. Need enough time for the radar to detect, identify and lock the target, fire the missile, and have it track to the target, and something moving fast and high will be in and out of the range of the radar before all that can be done. Especially if the target is high up at 10km, which would half the effective range.

    The difference is that Reddit was still largely usable after the API changes and most affected users weren’t getting banned. Some people have a high tolerance for ads, but a lot of people would find YouTube unusable without an ad blocker, and if YouTube was banning people, they’d be destroying a lot of the inertia against going somewhere else.

    If we say that something like 20% of users on YouTube are using adblockers, that’s a big enough addressable market for a competitor to seriously take off. Enough to attract content creators and VC funding to get it off the ground. In the end YouTube would probably win, but it would be after a few years of actually having to compete. The revenue loss over that time period isn’t worth the short term gain of getting some small percentage of users to watch ads.

    If YouTube felt like it could get away with banning people using ad blockers and requiring an account to watch, they would have done it a decade ago.

    I doubt they’ll ever actually do it, just threaten it constantly.

    They’d rather have people without accounts, and/or using adblockers keep using the site. If they started actually cracking down, then it would create a significant pool of users who would use some other platform. They’d rather eat the losses of some people not viewing ads then push a significant amount of users to a potential competitor.

    Much like how Microsoft hasn’t cracked down on unlicensed windows installs because it would push a significant amount of people to look for an alternative OS.






  • Honestly, I’m just surprised this is the first time someone has dared to put a phone SOC in a laptop chassis.

    It seemed kind of obvious to me that a laptop experience on phone hardware (but like… with a bigger screen, keyboard and mouse/trackpad) was sort of perfect for most use cases. I just assumed that it would come in the form of a phone docked in to a hollowed out laptop. The core issue was just that the software was awful with such a set up. Apple just kind of bypassed that by having their whole OS and everything on it switch over to ARM and just running a non-mobile OS on a phone SOC.

    It seems like Google is kind of edging that way by merging chrome OS in to android. And windows was maybe flailing that direction with windows on arm… but… I think that was mostly just them trying to copy Apple without really thinking to hard about it.
