Infra-Red, In Situ (IRIS) Inspection of Silicon

from bunnie's blog [alt+shift+b] in programming

Cryptography tells us how to make a chain of trust rooted in special-purpose chips known as secure elements. But how do we come to trust our secure elements? I have been searching for solutions to this thorny supply chain problem. Ideally, one can directly inspect the construction of a chip, but any viable inspection method […]

Winner, Name that Ware July 2026

The structure in question for last month’s ware are a pair of NPN transistors that form the core of a bandgap voltage reference circuit. As its name implies, a bandgap voltage reference generates a near-constant voltage for use inside chips. The voltage is intended to be fairly constant over process variations, temperature variations, and power […]

AI Assisted Sermon

Once a year at my church, I usually give one sermon. I was asked to tie the theme to a young adult retreat we had taken to the Sunshine Coast. My first experience giving a sermon was many years ago at my old home church in El Monte, California. It was a Vietnamese-American church, but…

Must we always use LLMs this way?

As with my last post on AI, let me open with a statement: Just because most people hold AI a certain way, doesn’t mean that we always must, either now or in the future. As I noted in that piece, and my shades of gray post, I am well aware — and agree with — … Continue reading Must we always use LLMs this way? →

Revisiting Buttons and Cursors

The CSS Working Group resolved to use cursor: pointer for buttons and other clickable form controls in the new appearance: base styles. That happened on October 21, but I posted about it yesterday and, uh, people have feelings about cursors. I wrote about buttons and cursors back in 2022, when a post titled "Buttons shouldn't have a hand cursor" was making the rounds. I admitted I didn't have a strong opinion either way, then argued that not using the hand cursor had become the new anti-pattern anyway. The web isn't an operating system, and people expect clickable things to show a hand. The issue is Cursors For Base Appearance in CSS Forms Level 1. The group adopted the rules from this comment, and the part that's triggering half the Web is: select, option, input[type=checkbox], input[type=radio], button, input[type=button], input[type=submit], input[type=reset], input[type=color], input[type=image], ::file-selector-button { cursor: pointer; } It seems like we have a tabs vs. spaces sort of debate. Again. Nicole Sullivan pulled cursor data from a bunch of design systems and, in September, 27 of the 33 systems that set a cursor used pointer. After she added more systems, it was closer to a 50/50 split. Elika Etemad made the usability case in the meeting. Per the minutes, she said the hand "makes it clear, as soon as you're hovering an interactive control, you're supposed to click on it," and called it a "usability benefit even if not historically done on some platforms." "But the hand means it's a link" Haz had an interesting reaction: The debate is over, and evil has won. His point is that he can't tell whether ⌘-clicking something will open it in a new window anymore. He feels more confident clicking a button when he knows it won't change the URL, like when it just opens a popover or a panel. He's not wrong about that.* I replied that I've been on team evil since 2022 (albeit without a strong opinion, just following what users seem to expect). Touch screens don't have a cursor at all, and on desktop, browsers show a link's URL in the corner when you hover it. That's some type of hint, at least. Haz pushed back that he'd have to watch the bottom-left corner with his peripheral vision, which is fair. He also said he never cared which cursor buttons got, he just wanted links to have their own. I can appreciate that. "But desktop apps don't do it!" Jacob Paris liked the standard cursor on buttons because it makes web apps feel more like desktop apps than websites. My opinion hasn't changed, though. People have already learned that a hand cursor means clickable on the Web. It's by no means mandatory, but it's familiar and satisfying, so it stuck. Either way, nothing changes today. The resolution only covers appearance: base, which browsers haven't shipped yet. Buttons and selects still use appearance: auto, and their cursor is still default. If your CSS reset, design system, or web components already set cursor: pointer on buttons, keep it. When appearance: base ships, controls that opt in will get the same cursors by default. But remember, these are only defaults! You can still add whatever cursor you want to whatever element you want. Nobody's gonna stop you. In 2022, I said I'd keep changing the cursor on buttons until there's a good reason to stop. In 2026, I still haven't found one…and neither has the CSS Working Group. *Thinking about this more, if 50% of design systems opted to add cursor: pointer to buttons already, isn't this already a moot argument? **In general, I think the Web should be more personal and expressive so who even cares about a default? This is especially true for personal and fun sites. Just don't go too crazy, especially when it affects accessibility and the overall user experience.

TokyoDev Welcomes Its Head of Operations

TokyoDev has grown substantially over the past few years. We’ve expanded our community, dramatically increased the scope and frequency of our events, and have curated a library of articles for international developers. Despite all that, the way we run the business hasn’t changed much. I’ve continued to coordinate most of these activities myself, making the final decisions and keeping everything connected. In short, TokyoDev cannot run without my daily input. That approach worked well when TokyoDev was smaller, but it’s increasingly limiting how much we can accomplish. To help the business grow further, I wanted to find someone to take over some of my responsibilities and bring a fresh perspective. This is a significant step for me personally, as while I have worked with many contractors over the years, I have never actually hired a regular employee. Most importantly, I wanted to ensure that this person was someone I could trust to understand what TokyoDev stands for, and to make decisions in line with our philosophy. So I’m happy to announce that Scott Rothrock is joining TokyoDev full time as our Head of Operations. About Scott Scott has lived in Japan for nearly 20 years and has worked as a software engineer in multiple industries and environments, including small Japanese-owned businesses, overseas employers, and international companies based in Japan. Until the end of October 2026, he was the head of the Japan Markets team at Kraken Technologies, where he led an international team of software engineers in delivering complicated, regulated products on strict timelines for Japanese electricity and gas retailers, while also ensuring compliance with evolving organizational and global standards. He’s made a name for himself both inside and outside Japan as a kind, effective mentor who can cultivate great engineers and leaders. Scott’s previous role in TokyoDev Some of you may already know Scott in another capacity, as he has been involved with TokyoDev since 2022. He began as a community volunteer and later became our community manager, which also included responsibilities such as managing our article pipeline from submission to publishing. When I created TokyoDev’s Discord, I had no previous experience running an online community. Scott joined soon after I started and began helping other members, stepping in when people behaved inappropriately, and configuring our roles and permissions and safety features. I was impressed by his initiative and asked him to become an official moderator in January 2023. Outside of his role as a moderator, Scott has always pushed TokyoDev to grow; for example, he arranged internet events such as livestreamed AMAs and interviews. He organized TokyoDev’s first meetup as a volunteer in February 2023, which taught me that there was interest in TokyoDev events outside of the internet. By the end of 2023, I had brought him on as our part-time community manager. What I saw throughout his tenure was that Scott continued to take initiative in expanding TokyoDev. Scott was one of our first external contributors, writing about his experience living with a disability in Japan. He encouraged me to expand and refine both our editing and submission processes so that we could reach out to even more contributors and platform their perspectives. The editorial team now consists of him and Rebecca Callahan, and they’ve had a hand in every article that TokyoDev has published. In other words, since 2022, Scott has shown that he cares about TokyoDev as much as I do. He is invested in what we do and why we do it, and shares my vision for what TokyoDev can become. What changes now Scott’s experiences as an engineer, a mentor, and a leader make me confident that, as our Head of Operations, he will continue to help TokyoDev mature. A big part of what has made TokyoDev successful is that I see the software developers who use our site as my peers and genuinely want to help them. Scott shares that perspective, and will join me in ensuring that TokyoDev remains true to its principles while we grow. So what changes in the short term? Nothing dramatic. I will teach Scott about managing TokyoDev as a business, and he will document our processes and products as a part of that learning. He will also look for areas of improvement while ensuring that we remain compliant with regulations and labor law. Over time, I will hand over some other responsibilities. I will continue to run TokyoDev, but TokyoDev will become less dependent on me for its day-to-day operations. Long term, I’m excited about what this will enable us to do. TokyoDev has always been about helping international software developers build successful careers in Japan, and bringing Scott on full time puts us in a much better position to continue doing that. We look forward to writing the next chapter of TokyoDev together.
