  • Waymo doesn’t give a shit if their cars are ugly and can cover them in dozens upon dozens of cameras and sensors. They’re not selling them to consumers who care about looks, they are renting them to riders who don’t want to die on the short trip. They also only operate in a small region of the country with limited weather conditions and frequently stop service when weather is bad.

    Tesla is run by an idiot who insists that a pair of cameras and a single lidar sensor that they keep deciding to disable can somehow magically always work in all weather and lighting conditions and is selling to consumers who don’t want an ugly car and expect to be able to operate their purchase at all times

    Different constraints leads to different levels of success



  • I’m always unsettled when discussing this topic that people can readily accept and understand that pets are unable to digest the same foods as us when it comes to toxic things like grapes or chocolate. Their livers and kidneys can’t break those compounds like caffeine and tartaric acid down as an efficiently as ours.

    Similarly people readily accept the idea that a bird can eat nightshade and a deer can eat poison ivy because their bodies can digest foods ours can’t.

    But that somehow doesn’t help them infer the same thing can mean those animals cannot get their nutrients from foods the same ways that we can and vice versa. That human dietary concepts don’t just magically apply to the whole animal kingdom


  • Unlike omnivores, cats are unable to synthesize arginine, taurine, methionine and cystine, arachidonic acid, niacin, pyridoxine, vitamin A and vitamin D from their own organs and must get it from other sources. Their livers and kidneys simply cannot make this material from other materials. For the most part this list of nutrients is not available in complete form in plants.

    Our bodies for example make vitamin D from sunlight via our skin (d7). But can also get it in multiple base forms and synthesize it from animal based foods containing d3 or from compounds containing D2. Cats however only have the ability to use D3 and cannot synthesize D7 or convert D2 to D3 (omnivore liver)

    In theory you could make food in a lab that is technically vegan and supplies the above nutrients. Nobody has done this.





  • unique screens have unique canvas fingerprinting.

    Exactly what I just said? Don’t use unique screens and you are less identifiable. The most anonymous browser is a freshly wiped two year old Apple device running safari or chrome from a university campus or coffee shop. A million other laptops have the same base canvas fingerprint.

    Fewer people use Linux. Fewer people use specialized browsers. Fewer people have external displays. All those things make you easier to fingerprint than a vanilla machine.

    Is it possible you misread what I typed?






  • Every time someone says something like this I have to explain CDC and regular old backups. There’s no way in hell Reddit doesn’t keep cold and hot backups of their shit. And while Reddit is unlikely to be doing CDC for soc2 or other compliance reasons, it’s the easiest method to capture data for analytics purposes.

    CDC stands for change data capture. It’s generally done with databases by streaming the change log or ref log to a bucket or a service like Kafka where you can fast forward and rewind the log queue to see the state of the DB at any point in time. Even if you edit your comments it’s likely sitting in a Kafka topic or a snowflake bucket outside of the DB or cache used for the presentation layer.

    Zero large scale websites operate with a truly single data store. There is always another layer that your user operations don’t impact







  • Seconding the other comment, lots of orgs picked .lan and then over the last few years have moved things into the cloud and .lan has become a meaningless soup since half the shit isn’t even on local network. Now it just means “needs a vpn or ztn to talk to”

    Luckily my last three orgs finally bought a second domain for private dns. It’s quickly becoming a pattern that myorg.com owns myorg.tech or whatever for private traffic. Domains are cheap as fuck compared to everything else a business spends money on, it’s really silly how many people are using hacks for this
