“It feels fragile because of the Internet”

This blog post about using a 14-year-old PowerPC Mac Mini running 12-year-old OS X Leopard has this musing towards the end:

Something about using this feels very fragile, and not because of the machine itself, the operating system, or even the interface. It feels fragile because of the internet.

The internet has so aggressively taken over our lives that we can’t imagine a computing experience without it. And when it’s no longer there on a platform that didn’t really work properly without it, it becomes impossible to use in many ways. One has the feeling that even older operating systems won’t feel this broken in retrospect, because their experiences are otherwise separate from the internet and work without it being at the center of the experience.

I remember this period of “even older” operating systems in the 90s, of coaxing my Pentium desktop PC to run Red Hat Linux 5 and work on it for a whole day – tinkering, programming, writing, simple gaming – without connecting to the internet, or for that matter without any part of the OS being internet-first. I’d “go online” by dialling the modem via a shell script, look up what I wanted to all at once, then disconnect. The internet was like a trip to the library instead of being the environment itself. No chat client ran perennially, no mail client polled for new email. No iCloud Drive synchronised silently with the Cloud (the term didn’t exist then) in the background.

It wasn’t necessarily a better or worse time, just that it definitely was different.

My 2018 talk on crypto tokens is now online

This was before the 2018 crypto winter, when ICOs were still being launched every week for projects that hadn’t even gotten of the ground (many of the high-profile ones still haven’t, in mid 2019), and ads still ran for tokens that guaranteed returns. I described what made it more likely that a token-based project would be successful.

Libra makes P2P exchange of securities possible

This article brings up some great points about Facebook’s Libra that I have also been thinking about.

That since the underlying basket includes short term securities, that Libra is also a security, not a currency as FB describes it. It behaves more like a (stable) ETF, and so a transfer is a buy/sell transaction that should attract (minsicule) capital gains.

Using securities as a means of exchange is quite existing. My colleagues and I in the fin-tech space have often discussed idly how it would be useful to simply transfer mutual fund, ETF or stock units from one to another, P2P, instead of via an exchange. Transferring liquid fund units is as close to making fiat payments as possible – bypass the bank account altogether.

Perhaps this is what banks and the US Congress should be worried about. Not that Libra as a currency will supplant the dollar. It won’t be a unit of account since it’s backed by fiat instruments and measures is stability by such. But that it makes P2P buying and selling of securities possible, keeping large amounts of capital outside of the banking system.

Raspberry Pis as low-footprint single-purpose machines

I’m excited about the new, more powerful Raspberry Pi. This Hacker News thread describes several interesting hardware projects that the people have used the Pi for. And the Raspberry Pi website positions the new, more powerful Pi 4 as a Linux desktop machine.

I’m interested in its use as a low-power, low-footprint single-purpose machine, and having a few of them across the house.

For instance I have a privacy-focused Pi that’s physically tied to my router and serves as a network-wide ad- and tracker- blocker via pi-hole. It also runs cloudflared to encrypt my DNS lookups over HTTPS. I’m also setting it up as an OpenVPN server.

Another one is about to enter service as a XBMC/Kodi machine for movies and TV shows. This lives behind the TV. I’m also considering a third to serve as a Time Machine via netatalk and general-purpose backup machine via Syncthing. This will probably be behind my desk.

Taken together they’ll draw less power and run quieter than a desktop machine that does everything, and will be near-invisible too. It’s a new class of personal computer.
