pmw··on Raspberry Pi Shortages Could Last Another Year
A normal computer has features I want to avoid, such as size, heat, fans, large power supplies, etc. A single-board ARM or RISC computer has all the compute power and peripheral connectors I need. The only missing piece is sufficient RAM.
pmw··on Raspberry Pi Shortages Could Last Another Year
I am excited for VisionFive 2, "the world’s first high-performance RISC-V single board computer (SBC) with an integrated GPU."

https://www.starfivetech.com/en/site/boards

But my problem with all these SBCs (including VisionFive) is they max out at 8 GB of RAM. This is a problem for me because I want to run an Ethereum validator, and the software stack needs 16+ GB RAM. Is anyone aware of an SBC supporting 16 GB?

pmw··on Mastodon’s eternal September begins?
> in anarchist circles when you have a smallish and relatively close group you can manage a very positive and supportive atmosphere without rules and protocols. But as things grow you lose that, inevitably, as having more people means needing more formalized ways of handling issues.

pmw··on Why I’m Cryptophobic
Both the argument and your counter argument are discussed by Lyn Alden here: https://www.lynalden.com/cryptocurrencies/.

She proposes three ways, including valuing cryptocurrency as we do precious metals.

pmw··on Is IPv6 faster than IPv4?
AWS supports IPv6 on non-default VPCs: https://docs.aws.amazon.com/vpc/latest/userguide/get-started...

I have a hobby project on AWS using it today, with multiple EC2 instances having IPv6 addresses. It works beautifully.

> I imagine the FDA has zero tolerance for vendor software that is bundled with dark patterns

Here's a recent case of a nurse going to prison for a medication error, where the UX of the medical cabinets is blamed in a big way: https://khn.org/news/article/radonda-vaught-fatal-drug-error...

> The case against Vaught hinges on her use of an electronic medication cabinet, a computerized device that dispenses drugs and is widely used in hospitals > > ... > > Vaught triggered an override that unlocked a much larger swath of medications > > ... > > Some experts have said cabinet overrides are a daily event at many hospitals. > > Vaught insisted in her testimony before the nursing board last year that overrides were common at Vanderbilt, and that a 2017 upgrade to the hospital’s electronic health records system was causing rampant delays at medication cabinets. Vaught said Vanderbilt instructed nurses to use overrides to circumvent delays and get medicine as needed.

pmw··on Mozilla Thunderbird Beta now supports Matrix chat
Fastmail has been that all-in solution. They host Mail/Calendar/Contacts, and they used to host XMPP/Jabber. But unfortunately they made the decision to shut down XMPP (https://fastmail.blog/historical/shutting-down-our-xmpp-chat...) and probably for the same reason won't get into Matrix.

pmw··on Entropy isn't sufficient to measure password strength
This is a good place to advertise https://phrase.shop - a webapp I wrote that makes secure yet memorable passphrases.

It makes entropy requirements explicit, and you can even roll your own dice to supply the required entropy to generate your passphrase.

Try it, it's fun!

I'm a happy customer of https://bazqux.com. It is a paid RSS reader that seems to be developed by one guy. The web UI is very good, and it's supported by Reeder, an iOS news aggregator app I use.

pmw··on I still use plain text for everything. (2016)
I am a fan of Apple Notes because they support syncing with Fastmail's Notes[1], so I could access my notes from iPhone and web, and my data is not locked into Apple's ecosystem.

But I got irritated with Apple Notes. It lacks Markdown support. It auto-converts my note from plaintext to rich text anytime I start numbering, bulleting, or pasting, without a way to convert the note back to plaintext. Lastly, my notes had no structure or hierarchy. They were simply sorted by last-modified date.

So this month I researched note-taking apps having (1) Markdown support, and (2) support for syncing my data to Fastmail. Because again, I don't want to be locked into Apple. I settled on 1Writer[2]. It syncs to WebDAV endpoints, which Fastmail offers. My notes are now files, and I can organize them into folders, all within 1Writer.

For now, I love it. Markdown support is great, including highlighting in edit mode, and I don't miss anything from Apple Notes.

Go, plain text and open standards!

pmw··on Ask HN: How to stay focused and motivated working from home?
In the morning, I write down (and tell my team at standup) what I plan to accomplish today. I need to feel that the plan is doable, and my team needs to feel that the plan is making good progress toward our goals.

As I go through the workday, I move tasks from "need to do today" to "doing" or "did today". The "did today" list becomes what I tell my team the next day at standup.

I also have lists for "need to do this sprint" and "need to do sometime (non-sprint work)".

I track my time working. I use an iOS app called ATracker Pro, and I like it because it's local-first and simple. When I am engaged in work or doing something work-related and mandatory (trainings, OS upgrades, etc.), the timer is ticking. When I step away for lunch, bathroom, breaks, etc., or feel like browsing Hacker News for a while, I stop the timer. I have a goal for myself of 7 hours of work a day, and 35 hours of work a week. The app notifies me when I hit the goals. Some days I manage only 5 hours, while other days I exceed 10.

The time tracking is for me to stay accountable to myself. My workplace doesn't require me to track/log time. It's simply for me to know that I am giving my employer the time they expect of me... not less, and preferably not more. It helps me to find work/life balance. I can allow myself to take a nap in the middle of the day, or start work late, and know that it'll work out.

I try to be consciously aware of procrastination. The timer is to help with that (so I stop the timer if I feel like procrastinating---then I can do so guilt-free). But also, I am aware that procrastination is an emotion management problem, not a time management problem. Reflecting on that helps me to break out of it. I ask myself, what do I feel negatively about? Is the task too vague? Are the implementation details unpleasant? What's the smallest step I can take to make progress?

Lastly, I recommend the book "The 7 Habits of Highly Effective People," specifically the first three: Be Proactive, Begin With The End In Mind, and Put First Things First.

I disagree. As Michael Bolton said, "Why should I change? He's the one who sucks!"

Kilo, mega, and other prefixes predate computer storage, and SI is beautiful because it is consistent. The computer industry decided to use standard prefixes with non-standard (base-2) quantities. Now let's cut our losses and return to consistency with everything else.

I've never had the WHOOP, but I use Apple Watch combined with iPhone apps to track heart metrics. I recently discovered AutoSleep and HeartWatch, which both track HRV along with other metrics.
pmw··on Show HN: Phrase shop: make secure and memorable passphrases
Thank you, both good ideas. I'm not sure right now about how to support more dictionaries without making the UI too busy, but it's something I'd love to find a solution for.
pmw··on Biohacking Lite
> Doing 5 sets spread out over the entire day, I could lift more and saw results pretty much right away, and really for the first time. I'd exercise while waiting for things like the drier to ding or toast to pop up, a file to download, a commercial break or a cut scene to finish.

For anyone interested in learning more about this, it's called "greasing the groove". There are plenty of web articles about it, and it's also covered pretty thoroughly in the book _Overcoming Gravity_ by Steven Low.

pmw··on Ask HN: My wife might lose the ability to speak in 3 weeks – how to prepare?
This reminded me of some wonderful writings from Roger Ebert, a brilliant man who also lost his ability to speak.

I cannot find it now, but I believe he wrote about this exact phenomenon: even with the best technology, you cannot communicate as fluently as a conversation demands, so you're relegated to the background.

Here's one of his writings I was able to find: https://www.rogerebert.com/roger-ebert/i-think-im-musing-my-...
