  • It is true, don’t do it.

    Even at huge companies like Google, lots of stuff was keyed on your email address. This was a huge problem so Google employees were not allowed to change their email for the longest time. Eventually they opened it up by request but they made it very clear that you would run into problems. So many systems and services would break. Over time I think most external services are pretty robust now, but lots of internal systems still use emails (or the username part of it) and have issues.

    IIUC Google accounts now use a random number as the key. But there are still places where the email is in use, slowly being fixed at massive cost.



  • Prom is fun. You get to hang out with all of your classmates, ask someone out. A subset of people are always going to go overboard, but keep in mind that you don’t see the “normal” cases. Most people just walk up to someone and ask them out. They find a date from the school or go alone.

    I’m from Canada so I don’t know if the US is wildly different, but here it is a bit of a big deal, but I think part of that is what makes it fun, you sort of build a bit of hype around what would otherwise be just another school dance.






  • I don’t know why everyone is so negative. The gameplan seems pretty clear to me.

    1. Make expensive fancy product. This is effectively a “devkit” that companies can use to start experimenting with AR software.
    2. Make lower cost product. There are now a few decent apps available and early adopters will be willing to buy it to be one the leading edge.
    3. Now there is a bigger market, leading more companies to be willing to develop apps.

    Apple is hoping that this is enough to break the chicken-and-egg cycle. Enough to get a few powerful apps such that more regular consumers will be willing to buy which again increases the addressable market which makes it more attractive to companies.






  • I am a touch screen enjoyer. At least in theory. I like having time to browse, look at pictures, easy access to customization options and most importantly no feeling of pressure. I am not spending a cashier’s time and potentially blocking someone behind me (at least there is usually less of a line for the self-ordering).

    However there are negatives for sure. My biggest annoyance is that these devices are often annoyingly slow and unresponsive. They just display a tiny bit of text and images, they should switch between screens at 60fps, not 2s per click. Also if I know what I want it is often faster to tell the cashier and let them enter the order (on their more expert-optimized and less laggy keypad).





  • Because to implement this you need to negotiate with individual credit card issuers. Basically how this works is that your phone is being issued a virtual card with the keys locked inside the phone’s HSM. Then it can be used to make NFC payments just like any physical card. So you need 1. contracts with many card providers, 2. card issuance processes with these providers 3. huge amounts of compliance bureaucracy. At the end of the day it isn’t really worth it unless you are a huge company and expect to have tons of users or see it as an essential feature of your phone OS.
