  • In North America and Europe, tap to pay was implemented prior to smartphones that could scan QR codes being ubiquitous. Most of us have had cards that support NFC payments for longer than we have had a phone that can read QR codes so it made sense for phones to pick up the technology that worked with the terminals businesses already had than try to implement a new system.

    The QR code thing is primarily a Chinese solution to the payment problem (all other Asian countries I’ve been to have widespread NFC acceptance). Payment cards were never widespread within China the way they are in other places, until AliPay and WeChat Pay became a thing people still primarily used cash for their daily communications. If businesses don’t already have credit card terminals but people have smartphones then the QR code starts to make more sense.

    One interesting thing about this is that even before North America was widely using NFC payments, people in Hong Kong were using their Octopus transit cards as contactless payment at all kinds of businesses throughout the city. Yet that technology didn’t seems to make it into Mainland China.










  • I’ve interviewed many people and most people are terrible in that situation, even when I try to help them along.

    Nervousness is the number one thing that throws people off during an interview. Instead of taking a breath to calm down and think things through they either immediately start speaking without a clear plan, or they clam up and don’t give me anything to talk about. Using the STAR/START method of answering questions works great to give a framework.

    The next is that they just don’t demonstrate their skills or that they learn over time. I’ll ask a technical question about something and they show no understanding of why they did something. I love asking questions about what a person learned while doing their work, so many people just don’t have anything to share.

    Lastly, interviews are way easier if the other person treats it like a conversation rather than a one way Q&A session. I get a much better idea of what they will be like to work with and I’m more comfortable when I can ask questions that continue on the discussion. On the flipside, some people take over conversations and don’t get that our time is limited and answers need to be concise. That said, even if the interview is the conversation style, make sure to save at least a couple questions for the ending when you are inevitably asked for questions.


  • I recommend dual booting, not a VM. It is easy enough to choose which OS to boot into if you need to go back to Windows, while being enough friction that you don’t immediately fallback to going into Windows every time you don’t know how to do something in Linux.

    I don’t code, but from the gaming standpoint, things are pretty decent on Linux these days. I’ve been on Linux full time on my laptop for well over a year now, and 6+ months on my main desktop now and find very few reasons to boot into Windows. I think I booted into Windows last weekend for the first time in at least 2 months because I had to upgrade the FW on a device that only had a Windows tool. Otherwise I do have a windows VM on a server that I use relatively frequently, because the state of 3D CAD software on Linux is horrible.





  • 10+ years experience in product design here. There is nothing about a “simple” product that is cheap or easy. Say you hire a design engineering firm to design it, who is going to make the parts? Have you ever worked with manufacturing in Asia? Who is going to assemble it? Who deals with the inevitable issues?

    Then you have to think about selling it. What certifications do you have to get?

    That is just hardware, now repeat many of these same questions for firmware and app development.

    Now you have a product, what are the customers and who do you need to hire to market and sell to them? Assuming someone is interested in purchasing it how much money do you have to pay for all the product up front and warehouse it?

    There is a damn good reason why so many Kickstarter projects never actually ship. Hardware is hard even if you know what you are doing.


  • Obsessive apologizing makes a person appear not confident in themselves. If it is a person I care about I want them to be confident in themselves.

    Additionally the more you repeat something the less meaning it has. So if someone apologizes too much for things that really don’t necessitate an apology when they have something they genuinely need to show remorse for and apologize for the apology holds less meaning.





  • I don’t know what it is but I’ll read my posts before posting and then come back later and it will have an obvious autocorrect error I missed.

    It pisses me right off how bad predictions have gotten on every keyboard. SwiftKey and Swype were damn near perfect at one point and now I swear it purposely chooses the wrong word.
