JMP: Computing International Call Rates with a Trie
A few months ago we launched International calling with JMP.  One of the big tasks leading up to this launch was computing the rate card: that is, how much calls to different destinations would cost per minute.  While there are many countries in the world, there are even more calling destinations.  Our main carrier partner for this feature lists no fewer than 59881 unique phone number prefixes in the rates they charge us.  This list is, quite frankly, incomprehen … ⌘ Read more

@lyse@lyse.isobeef.org Excellent use of old denim, and also excellent use of long-form twt!

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.

Profanity: Profanity on Pinephone
Hi all,

So far, in my pinephone I used mainly GUI applications, because I was using a touch screen. Terminal applications are not user-friendly when it comes to one-handed operation.

I tested different distributions on my pinephone (mobian, manjaro, archarm), but usually most based on Phosh. In my opinion it is currently the best mobile graphics environment and stable as well.

In Phosh I tested few xmpp clients:

Will have to take a look at Gogs. Ideally wanting it to be easy to have the same ease-of-use to setup a web page as Github and Gitea.

I’ve been running some internal usenet groups for a while, now I’m starting to make more use of them and slap them on the web - https://omg.singles/T7ggI

exciting release for us, but some users on ARM-based systems reported some
difficulties upgrading to … ⌘ Read more

Hopefully OneUI 4 will extend the life of my smartphone
Last year I wrote about how I check the battery health of my smartphone. The app I used for that shows a notification when a certain charge level is reached that you can unplug the smartphone so it doesn’t charge to 100%. ⌘ Read more

How Docker Desktop Networking Works Under the Hood
Modern applications make extensive use of networks. At build time it’s common to apt-get/dnf/yum/apk install a package from a Linux distribution’s package repository. At runtime an application may wish to connect() to an internal postgres or mysql database to persist some state, while also calling listen() and accept() to expose APIs and UIs over TCP […]

File Sharing with Docker Desktop
One of the topics users of Docker Desktop often ask us about is file sharing. How do I see my source code inside my container? What’s the difference between a volume and a bind mount? Why is file sharing slower than on Linux, and how can I speed it up? In this blog post, I’ll […]

@benk@kwiecien.us I am using jenny (we chatted a bit on IRC earlier today). I have been using it for over five months now, I think. It is truly a joy to use, specially because you can use the power of Mutt/NeoMutt to read your twts.

Peter Saint-Andre: Philosophies and Ways of Life
In his book What Is Ancient Philosophy?, Pierre Hadot almost singlehandedly resurrected the ancient conception of philosophy as a way of life. Consider this observation about the philosophical schools of Greece and Rome: “For us moderns, the notion of a philosophical school evokes only the idea of a doctrinal tendency or theoretical position. Things were very different in antiquity. No university obligations oriented the future philosopher toward a specific school; instead, the futur … ⌘ Read more

@benk@kwiecien.us I meant literally a few minutes 😄 @prologic@twtxt.net told me he’d just implemented it. Btw, which twtxt client are you using now, Ben?

@prologic@twtxt.net let us take the path of less resistance, that is, less effort, for now. I am going to be a great-grandfather before search ever get implemented locally, least one to search on “all pods”. In other words, let us don’t bite more than we can chew. 😹 Neep-gren!

@prologic@twtxt.net I fully agree with making it a pod-level setting (forget about user-level, let us not complicate things too much; we all know users know nothing). Should I send a latinum over for this, or will an issue just suffice? Neep-gren!

@benk@kwiecien.us https://yarn.social/ has support for fetching feeds over gemini since a few minutes back! Not serving them there that I know of, but that’s just a matter of pointing your gemini server to the twtxt.txt file.
