Re:Swap, ZRAM, Zswap and Hibernate on NixOS on Wednesday September 23, 2026 @05:23PM (#49822794)
Right, you are good to do swap files on btrfs since linux 5.0 or so as long as you follow some rules. Disko thankfully covers all those details for you, but I shouldn't have skipped over that in the piece. I'll make an update when I get a chance.
This site tracks the status of what apps work: https://privsec.dev/posts/android/banking-applications-compa...

The official GrapheneOS docs contains a developer guide on how to fix banking apps when they are not working. Bank app developers have been surprisingly receptive to making the changes, weirdly enough. You can see in some of the issues tracked on the site where people reached out and the developers eventually made the apps work.

I've been running GrapheneOS for a while (I have posts on the blog in my bio if you want to see some day-to-day info) and only one bank app gave me trouble. I had to toggle a setting and then everything worked.

Separate from this is wallet and payment apps which still have not had much traction on GrapheneOS.

Found this as I was waiting for a delayed 77 bus today.
The book Here Comes the Sun by Bill McKibben is a really great read on the changing economics of solar. It came out August 2025 so its fairly up to date too.

Re:Google De-Indexed My Bear Blog and I Don't Know Why on Friday December 12, 2025 @01:13PM (#46246876)
Adding another data point from my own experience. I had a very similar case with my own blog which I detailed here: https://blog.matthewbrunelle.com/i-dont-want-to-play-the-seo...

Gone through everything I can find, but nothing has made a difference for months now. Would love to hear any thoughts people have that aren't the usual checklist items.

Good news is I still get some visitors through Kagi, DDG, and Bing.

Re:Testing out BLE beacons with BeaconDB on Saturday October 25, 2025 @05:13PM (#45707012)
Author here. I have a big backlog of posts, but I did this one first because I was trying to cram an explanation of BLE beacons into the project post.

> Is there something like war-driving for BLE Beacons?

Yup, that essentially what Neostumbler is! If you have an Android device go check it out.

My hope for the project is to make a little embedded device I can use, so I don't have to drain my phones battery. Also because it's fun to learn about a new topic.

I've been collecting a history of this sort of thing, and list of companies here: https://blog.matthewbrunelle.com/on-self-hosting-opentofu-an... . I'll have to add this one.

Let me know if there's more I can include!

Really feel a similar sentiment to a lot of others in the comments! I'm enjoying the recommendations other shared here.

This is really cool. I knew there was a policy on titles for submissions but not that there is also an automated process. Do you know if it's documented anywhere or are the details intentionally keep a mystery?
Yes I love Materialistic as well.

The link problem is also the only annoyance I have. Sadly it looks like many issues have been opened for the bug but I don't see any discussion on the tickets: https://github.com/hidroh/materialistic/issues?q=is%3Aissue+...

Re:Amazon Aurora Serverless on Monday August 13, 2018 @12:31PM (#17751333)
Very exciting! I made a simple bot to scrape lunch specials menus off Instagram and post them to my company's slack (http://blog.matthewbrunelle.com/projects/2018/05/07/Soup-Bot...).

One point point was making custom lambas to spin up/down the DB and everything that was needed to use it (a NAT on EC2, and an elastic IP since the default NAT aww provides is pricey). The bot only needs to run for an hour on weekdays so there's no point keeping everything running 24/7. Excited to try replacing all of that with this!

I've use instalooter as a library to great success: https://github.com/althonos/InstaLooter

Even made an issue on the repo when I ran into an issue setting it up on AWS and the maintainer was fast to respond.

Used it to make a bot to scrap soup special menus from a sandwich place near my work: http://blog.matthewbrunelle.com/projects/2018/05/07/Soup-Bot...

Here's the recording (https://skillsmatter.com/skillscasts/4964-railway-oriented-p...) of the talk that Scott Wlaschin gave at Skills Matter 2014 using what I believe is the the same slide deck. It was probably my favorite one from the day.

Warning though, you do have to make an account to view the video.
