After yesterday’s post about passkeys I got enough answers to learn how to use passkeys myself as a consumer. Here’s what I learned. If you want to try it yourself, passkeys.io is a nice demo server. Passkeys work a lot like passwords do today. You create a different passkey for each website and use it to log in. Your passkeys are stored in what’s called a “Passkey Authenticator”, agent software on your computer. (Behind the scenes passkeys use public key systems that are better than passwords.) Your phone probably works today as a passkey authenticator but most sites don’t support passkeys yet. Managing passkeys — backing up, migrating, sharing passkeys between devices — is still a work in progress. Android and Apple both support syncing passkeys between devices, that’s important so you can log in even if you don’t have your phone with you. Some software can also delegate. For instance Chrome on Windows will use Bluetooth to use a passkey on a nearby Android phone. The passkey...

Angkor Wat resources

I took an amazing trip to SE Asia last month, including Angkor Wat. I had a hard time finding good reading or other resources to learn from before I went, in part because Amazon is awash in AI garbage. Here’s some books and podcasts I found useful about the Khmer empire in general and Angkor in particular: Ancient Angkor by Michael Freeman and Claude Jacques. The closest thing to a coffee-table book to preview what you will see. The practical information is outdated but the pictures and descriptions are good. Empire Podcast #185: The God Kings of Angkor Wat by William Dalrymple and Anita Anand. An entertaining and fully detailed account of the Khmer empire. It’s basically an excerpt from Dalrymple’s new book The Golden Road: How Ancient India Transformed the World. Fall of Civilizations Podcast #5: The Khmer Empire by Paul Cooper. Another history, not quite as magically well told as Dalrymple but full of good information. Angkor and the Khmer Civilization by Michael D. Coe. A highly recommended history of the Khmer region. Honestly I found this very dry and too detailed, but I did learn from it. Lonely Planet Pocket Guide: Siem Reap & the Temples of Angkor. We didn’t use this much but it seemed like a useful practical guide. OTOH it dates to 2018 so things have changed. My other advice for visiting Siem Reap and Angkor is: go. It is amazing. Plan for at least two full days of touristing there. Hire a private guide and driver if you can, it is absolutely worth it. (Email me for a recommendation.)

Non-alcoholic apéritifs

I’ve been doing Dry January this year. One thing I missed was something for apéro hour, a beverage to mark the start of the evening. Something complex and maybe bitter, not like a drink you’d have with lunch. I found some good options. Ghia sodas are my favorite. Ghia is an NA apéritif based on grape juice but with enough bitterness (gentian) and sourness (yuzu) to be interesting. You can buy a bottle and mix it with soda yourself but I like the little cans with extra flavoring. The Ginger and the Sumac & Chili are both great. Another thing I like are low-sugar fancy soda pops. Not diet drinks, they still have a little sugar, but typically 50 calories a can. De La Calle Tepache is my favorite. Fermented pineapple is delicious and they have some fun flavors. Culture Pop is also good. A friend gave me the Zero book, a drinks cookbook from the fancy restaurant Alinea. This book is a little aspirational but the recipes are doable, it’s just a lot of labor. Very fancy high end drink mixing, really beautiful flavor ideas. The only thing I made was their gin substitute (mostly junipers extracted in glycerin) and it was too sweet for me. Need to find the right use for it, a martini definitely ain’t it. An easier homemade drink is this Nonalcoholic Dirty Lemon Tonic. It’s basically a lemonade heavily flavored with salted preserved lemons, then mixed with tonic. I love the complexity and freshness of this drink and enjoy it on its own merits. Finally, non-alcoholic beer has gotten a lot better in the last few years thanks to manufacturing innovations. I’ve been enjoying NA Black Butte Porter, Stella Artois 0.0, Heineken 0.0. They basically all taste just like their alcoholic uncles, no compromise. One thing to note about non-alcoholic substitutes is they are not cheap. They’ve become a big high end business. Expect to pay the same for an NA drink as one with alcohol even though they aren’t taxed nearly as much.

Legal aid charities for immigrants (2024)

The Trump administration has made aggressive threats against immigrants in the US. It’s not clear what’s coming, my biggest fear is a violent display of fascism. (Don’t call them camps!) But even if it’s a polite legal process it will be chaotic and disruptive to many neighbors. Back in 2018 I donated reactively to the Trump administration’s cruelty to immigrant families. This time I’m trying to get ahead of it. The need for the money is now, no matter what happens it is going to be a bad few years for immigrants in the US. To that end I asked on Metafilter about charities to donate to. I got back a remarkable reply listing 18 charities that all have some California focus. I donated to most of them. I want to highlight two groups in particular. One is RAICES. They work in Texas, not California, but they are well organized and effective. The other is KIND. They have a simple mission. They try to ensure every unaccompanied minor has legal representation in immigration court (something not guaranteed.) The other groups on the list are all also deserving of consideration.

AI enhanced search

LLMs are good search helpers. Here’s three search tools I use every day. All of these use an AI to synthesize answers but also provide an essential feature: specific web search results for you to verify and further research. I use these for conversational inquiries in addition to more traditional keyword searches. Phind is an excellent free LLM + search engine. The AI writes an answer to your query but is very careful to provide footnotes to a web-search-like list of links on the right. I use this mostly for directed search queries, things like “what’s an inexpensive TV streaming device?” where I might have used keyword search too. The Llama-70b LLM that powers the free version is quite good, sometimes I have general conversations with it or ask it to generate code. Bing CoPilot has a very similar output result to Phind. I find it a little less useful and the search result links are less prominent. But it’s a good second opinion. Bing has been a very good search engine for 10+ years, I’m grateful to Microsoft for continuing to invest in it. CoPilot results are sometimes volunteered on the main Bing page but you often have to click to get to the ChatGPT 4 Turbo enhanced pages. Kagi is what I use as my general search engine, my Google replacement. It mostly gives traditional keyword search results but sometimes it will volunteer a “Quick Answer” where Claude 3 Haiku synthesizes an answer with references. You can also request one. I think Phind and CoPilot do a better job but I appreciate when Kagi intercepts a keyword search I did and just gives me the right answer. Google has tried various versions of LLM-enhancement in search, I think the current version is called AI Overviews. It’s not bad but it’s also not as good as the others. Not mentioned here: ChatGPT or Claude. Those are general purpose LLMs but they don’t really give search results or specific references. In the old days they’d make up URLs if you asked but that’s improving.

8BitDo Game Controllers

8BitDo makes good game controllers. A wide variety of styles from retro to mainstream, with some unusual shapes. And wide compatibility with various systems: PC, Macs, Switch, Android. They’re well built, work right, and quite inexpensive. A far cry from the MadCatz-style junk we used to get. The new hotness is the Ultimate 2C, an Xbox-style wireless controller for the very low price of $30. But it works great, doesn’t feel cheap at all. The fancier mainstream choice is the Ultimate 2.4g at $50 which includes a charging stand and extra reprogrammability. But what’s really interesting to me are the odd layouts, often small or retro. The SN30 Pro is particularly interesting as a portable controller. SNES-styling but a full XBox style modern controller with two analog sticks, easy to throw in a suitcase. There’s a lot of fiddly details for this class of device. Controller type (XInput, DInput, switch, etc), wireless interface (Bluetooth or proprietary), etc. 8BitDo makes good choices and implementations for all that stuff I’ve tested. They seem to work well with Steam. They’re a popular brand so well tested. It helps that PC game controllers have mostly standardized around the Xbox layout and XInput. Steam can patch over any rough spots for older games.

Measurement and Numbers

Here’s Jony Ive talking to Patrick Collison about measurement and numbers: People generally want to talk about product attributes that you can measure easily with a number…schedule, costs, speed, weight, anything where you can generally agree that six is a bigger number than two He says he used to get mad at how often people around him focused on the numbers of the work over other attributes of the work. But after giving it more thought, he now has a more generous interpretation of why we do this: because we want relate to each other, understand each other, and be inclusive of one another. There are many things we can’t agree on, but it’s likely we can agree that six is bigger than two. And so in this capacity, numbers become a tool for communicating with each other, albeit a kind of least common denominator — e.g. “I don’t agree with you at all, but I can’t argue that 134 is bigger than 87.” This is conducive to a culture where we spend all our time talking about attributes we can easily measure (because then we can easily communicate and work together) and results in a belief that the only things that matter are those which can be measured. People will give lip service to that not being the case, e.g. “We know there are things that can’t be measured that are important.” But the reality ends up being: only that which can be assigned a number gets managed, and that which gets managed is imbued with importance because it is allotted our time, attention, and care. This reminds me of the story of the judgement of King Solomon, an archetypal story found in cultures around the world. Here’s the story as summarized on Wikipedia: Solomon ruled between two women who both claimed to be the mother of a child. Solomon ordered the baby be cut in half, with each woman to receive one half. The first woman accepted the compromise as fair, but the second begged Solomon to give the baby to her rival, preferring the baby to live, even without her. Solomon ordered the baby given to the second woman, as her love was selfless, as opposed to the first woman's selfish disregard for the baby's actual well-being In an attempt to resolve the friction between two individuals, an appeal was made to numbers as an arbiter. We can’t agree on who the mother is, so let’s make it a numbers problem. Reduce the baby to a number and we can agree! But that doesn’t work very well, does it? I think there is a level of existence where measurement and numbers are a sound guide, where two and two make four and two halves make a whole. But, as humans, there is another level of existence where mathematical propositions don’t translate. A baby is not a quantity. A baby is an entity. Take a whole baby and divide it up by a sword and you do not half two halves of a baby. I am not a number. I’m an individual. Indivisible. What does this all have to do with software? Software is for us as humans, as individuals, and because of that I believe there is an aspect of its nature where metrics can’t take you.cIn fact, not only will numbers not guide you, they may actually misguide you. I think Robin Rendle articulated this well in his piece “Trust the vibes”: [numbers] are not representative of human experience or human behavior and can’t tell you anything about beauty or harmony or how to be funny or what to do next and then how to do it. Wisdom is knowing when to use numbers and when to use something else. Email · Mastodon · Bluesky

The 6 Hours of Lex

When I drive the 24 Hours of Le Mans, I spend a total of about 6-9 hours in the car, divided into stints of roughly two hours at a time. It's intense. But talking with Lex Fridman in Austin on his podcast? Over six hours straight! We only interrupted the session for five minutes total to take three bathroom breaks. All that endurance training has clearly paid off! But the magic of a good conversation, like the magic of driving at Le Mans, is that time flies by. Those six hours felt more like sixty minutes. This is what flow does: it compresses the moment. Besides, we had plenty to talk about. Lex prepares like no other podcast I've ever been on. Pages and pages of notes. Deep questions, endless attention for tangents. We covered the beauty of Ruby for half an hour alone! But also the future of AI, small teams, why we left the cloud, Elon Musk, fatherhood, money and happiness, and a million other topics (which Lex mercifully timestamps, so listeners without six hours to spare can hop around). It was a privilege to appear. If you're interested, the conversation is on YouTube, on Spotify, on X, and as a regular podcast.

Computers Are a Feeling

Exploring diagram.website, I came across The Computer is a Feeling by Tim Hwang and Omar Rizwan: the modern internet exerts a tyranny over our imagination. The internet and its commercial power has sculpted the computer-device. It's become the terrain of flat, uniform, common platforms and protocols, not eccentric, local, idiosyncratic ones. Before computers were connected together, they were primarily personal. Once connected, they became primarily social. The purpose of the computer shifted to become social over personal. The triumph of the internet has also impoverished our sense of computers as a tool for private exploration rather than public expression. The pre-network computer has no utility except as a kind of personal notebook, the post-network computer demotes this to a secondary purpose. Smartphones are indisputably the personal computer. And yet, while being so intimately personal, they’re also the largest distribution of behavior-modification devices the world has ever seen. We all willing carry around in our pockets a device whose content is largely designed to modify our behavior and extract our time and money. Making “computer” mean computer-feelings and not computer-devices shifts the boundaries of what is captured by the word. It removes a great many things – smartphones, language models, “social” “media” – from the domain of the computational. It also welcomes a great many things – notebooks, papercraft, diary, kitchen – back into the domain of the computational. I love the feeling of a personal computer, one whose purpose primarily resides in the domain of the individual and secondarily supports the social. It’s part of what I love about the some of the ideas embedded in local-first, which start from the principle of owning and prioritizing what you do on your computer first and foremost, and then secondarily syncing that to other computers for the use of others.
