xDrip+ is an unofficial and independent Android app which works as data hub and processor between many different devices.

It supports wireless connections to G4, G5, G6, G7, Medtrum A6, Libre via NFC and Bluetooth, 630G, 640G, 670G pumps, CareSens Air and Eversense CGM via companion apps. Bluetooth Glucose Meters such as the Contour Next One, AccuChek Guide, Verio Flex & Diamond Mini as well as devices like the Pendiq 2.0 Insulin Pen.

Heart-rate and step counter data is processed from Android Wear, Garmin, Fitbit and Pebble smart-watches and watch-faces for those that show glucose values and graphs.

On some Android Wear watches, it is possible for the G5 or G6 to talk directly to the watch so it can display values even when out of range of the phone.

The app contains sophisticated charting, customization and data entry features as well as a predictive simulation model.

“A Hex Editor for Reverse Engineers, Programmers and people who value their retinas when working at 3 AM.”

I actually used it not too long ago to inspect why a mp4 file wasn’t valid. The pattern language that they have is quite nice and having sections of the hex highlighted and being able to see what structures they represent and what data was on those structures was very useful!

I think Netflix is a big user / sponsor of the project.

Looking through the docs, I still see no mention of version control or even migrations at all. Is this something that has been solved?

However, while trying to dig up the repo I did find https://github.com/J2TEAM/awesome-AutoIt#awesome-autoit that may interest the same audience

I just stumble across dotstow which adds a git layer on top of it https://github.com/clayrisser/dotstow

https://alexpearce.me/2016/02/managing-dotfiles-with-stow/

https://bastian.rieck.me/blog/2019/dotfiles_stow/

I'm starting to wonder if I just have a very vanilla dotfile workflow compared to what some other people use. This would surprise me a bit, given how I tend to go overboard in custom configuration for most things, but it definitely feels like my experience isn't enough for me to understand why specialized tooling for dotfiles is needed.

For example, the .gitconfig for work is different from home (e.g. my username/email). Ditto for my .ssh/config and my shell aliases.

I also use Nix to manage all my tools, and the home-manager configuration is slightly different between mac & linux due to platform support.

I've gone through a few iterations of home-built solutions, including extending homeshick[1], before discovering YADM which implemented everything I had done but better.

[1] https://github.com/andsens/homeshick

This was me for a long time - but then I started using ephemeral (EC2) hosts for remote development, and while I wasn't setting up a new machine frequently, knowing that I could do it with <5min of effort (and 15min of building Nix packages) eliminated a lot of anxiety.

Only played with it for a little but it seems well designed an simpler alternative to ansible, chef and other such things.

As someone who's never used any of the infrastructure tools, I'm thinking of pyinfra as a way to run shell commands + install dependencies on hosts (declaratively?) on a bunch of hosts via ssh.

Inventory is to sort of take a self-defined inventory on a bunch of hosts?

One final question on usage, would it be possible to sync or reference files from the machine running pyinfra on the remote hosts? Or would that have to be done indirectly via running shell commands to sync?

- ops are (mostly) declarative, but some (server.shell) will always execute the command given

- inventory is just that, basically a list of hosts to target plus associated data, docs page: https://docs.pyinfra.com/en/2.x/inventory-data.html

- absolutely for syncing files, check out the files.put and files.template operations (and the files ops in general): https://docs.pyinfra.com/en/2.x/operations/files.html

What would you say are key differentiators of PyInfra from these existing projects?

For ansible/chef, etc the main reasons/benefits boil down to:

- instant feedback esp on errors, get the stdout/stderr of whatever command pyinfra was executing, there’s no agent or abstraction to hide it

- configure in python rather than yaml+jinja2 mess

- integrate with the whole python package ecosystem

- speed and small overhead as inventories scale

BespokeSynth takes the concept of a modular synthesizer and expands it so that the application is less just a synth and more a complete modular DAW. I've used it to create MIDI/audio workflows that I couldn't get exactly the way I wanted in Ableton or FL Studio. It also has a module for doing livecoded audio processing in Python that I'm just starting to scratch the surface of.

I’ve posted this before but I love it so much I gotta do it again.

You plug in a piece of ASM from a video game ROM, and it gives you a first pass decompilation. On the left hand side you can edit this decompilation, and on the right there’s a side-by-side diff of the target ASM and what your source currently compiles to. It’s slightly gamified, looks great, is super easy to fork/share, and can be pretty addicting once you get into it. Super cool community.

I recently tried the Collabora Online integration in Nextcloud, but was quite disappointed with it, the right-to-left button was greyed out for no apparent reason, and creating shapes and moving then around felt sluggish (clicking the rectangle tool directly added a rectangle in the middle of the slide, which I could then drag around and resize, but the transformation tools seemed buggy and didn't really work well).

I'll certainly try out Cryptpad

I can recommend traefik as proxy too

It’s written in perl and the perl API for handling the metadata is documented, but I’ve never seen anyone use that directly.

They are masterpieces

https://github.com/usebruno/bruno

Alternative to postman, that's fully local and syncs to git easily. Unlike hoppskotch and insomnia that are free, but offer paid sync, Bruno just works in git. Unlike others, it doesn't dump JSON that's hard to diff, but has its own easily diffable format. You can share your collections in your existing git, with your existing accounts and PRs.

Also has integrated CLI testing.

He plans to sell GRPC later for money. HTTP and GraphQL API works now. https://www.usebruno.com/pricing

Bruno looks fantastic and it is only $9 USD for a preorder license right now. That is a pretty good deal to support this work.

But clearly they're planning to add it.

heh, that's neat: https://github.com/httptoolkit/docker-registry-facade (Apache 2) although the rest of their stuff seems to be AGPLv3 https://github.com/httptoolkit/httptoolkit-android/blob/v1.3...

In general the source for core components that can't really be used for anything else is AGPL, but all the generally reusable libraries are Apache 2 or similar. The goal is to share as much as possible, and let everybody access the source for everything, and fork for their own use or submit modifications or whatever, but without the risk that a proprietary product runs off with the core product in a different direction. Seems to be working reasonably so far!

Regarding Docker, you might also be interested in https://github.com/httptoolkit/docker-socks-tunnel (1MB Docker container that runs a socks proxy, for tunnelling traffic between networks) and this detailed breakdown of how the whole Docker interception setup works under the hood: https://httptoolkit.com/docs/guides/docker/#the-technical-de...

I have also been planning to add discord support soon.

A small cross-platform personal GUI database app for desktop, with support for images. A modern riff on the idea of MS Access (for those old enough to remember). I think I saw someone claim it's a clone of some Mac app, but I'm not a Mac person so I have no idea if that's true. It's my go-to app when I want to do some shopping research/comparison and collect my results, and I'm not yet sure what fields I will need in the DB. I like it more for that purpose than a spreadsheet.

The repo is archived (unfortunately), but the binary releases work for me for now.

It's really good, I use it with Shortcuts and saves me a bunch of time on small things that I don't want to create an app for this.

Some genius realized that you can actually embed valid win32 programs inside valid posix shell scripts, and found a way to make a C cross-platform solution out of it, meaning that you can write C programs that compile to a single executable that will run on (quoting the site) Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS

I use the Nextcloud app on my KDE Plasma laptop, and it works perfectly, I only realized this works when reminders started magically showing up on my laptop without me needing to set anything up

https://jtx.techbee.at/ https://www.davx5.com/ https://nextcloud.com/

it was used as a platform to research collaboration models.

fortunately, at the time some german academic institution offered grants to universities for publishing their projects as Free Software or Open Source, and so this platform was released under the GPL.

what is interesting about the platform is that it not only stores objects like say mongodb, but it also implements user and group management, a hierarchical access control system down to the object level, and messaging. further messaging implements pretty much all communication protocols out there: IRC, XMPP, SMTP, IMAP, and of course HTTP, FTP and more. and no, to get these it does not require a bridge to independent implementations of those protocols, but they are implemented natively into the server, and SMTP or IMAP or the webinterface will all directly access the same stored object.

what's more, the platform allows you to upload your own modules to extend it, which are stored in its object object storage, and can be updated at runtime. it has been used by the university to host various courses for more than 10000 users all handing in assignments at the same time.

i have been using this platform for my own websites pretty much ever since.

the university stopped development on the project more than a decade ago, but i forked it, and eventually added a REST API and implemented multi domain hosting on it so that i could serve multiple websites from the same service.

the code is old, and needs updating. TLS support is outdated, which is something that needs to be fixed before the project can be recommended to anyone else. the built in web templating system is using XSLT, which should be replaced with easier to use alternatives (or simply ignored, as as i do, by building all websites as SPA using the REST API instead. the REST API too, should be updated or replaced by GraphQL.

but aside from these problems the platform is usable like Backend As A Service. ever since adding the REST API, i have not done any custom backend coding, as the platform already provides any features i have ever needed.

the challenge throughout all this time has been to get other developers interested in using such a platform, instead of building yet another CRUD backend from scratch.

i don't currently have time to do any work on it (even its website is down), as i need to focus on paid engagements, but i have not given up hope to be able to revive it and make it popular some day.

Business intelligence tool. Not the prettiest but it is like one of those all in one types of tools. Can connect to any data source that has JSBC driver and most databases have a JDBC driver. Reports can be simple SQL scripts, groovy code, JasperReport or created used Excel, Word or PowerPoint. You can schedule extracts and FTP files ... It is a developers BI tool.

It does lack a management GUI and that stuff is very much DIY.

In other words, the library directly exposes the essential PDF object structure (pages, dictionaries, strings, numbers, streams, etc.) for easy editing, while abstracting away as much of the incidental PDF file structure as possible (encryption, compression, object references, the page tree structure, etc.).

Among many other applications, I've used it to

• Automatically repair minor PDF file format problems (of the sort that would be fixed by Open + Save in Acrobat).

• Concatenate multiple PDFs into a single PDF, adding a bookmark to the first page of each, with the bookmark title derived from information not contained within the PDFs or their file names.

• Losslessly reduce the size of PDFs in not-entirely-trivial ways. For example, I was given a ~1 TB set of PDFs that stored 1-bit monochrome scanned images as losslessly-compressed (RLE, LZW, or flate) 24-bit color images with every pixel either 0x000000 or 0xFFFFFF, but also stored color and grayscale images in the same way, and included important non-image data. libqpdf made it easy to loop through each PDF file, extract and analyze the pixel data for each image, and replace relevant images with JBIG2-compressed "true" 1-bit equivalents without otherwise modifying the PDF.

• Lossily recompress large images embedded in PDFs, but only if they matched certain criteria. Specifically, I had a large number of PDFs that contained lots of lossless high-DPI 4K screenshots of a specific application, where even relatively high JPEG compression maintained legibility, interspersed with images where such recompression was undesirable (photos, document scans, 1080p screenshots).

• Create PDFs by overlaying plain text on PDF forms — "paper" forms defined by PDFs, not PDF forms — without duplicating form content for each page.

[In the above examples, JPEG and JBIG2 compression was performed with other libraries, as these are out-of-scope for libqpdf itself.]
