was going to buy a house miles away from any DSLAM. As I use internet a lot, I wrote something to help handle the lack of bandwidth [1] mlvpn.

Then mptcp came, and I just did use a socks5 proxy with mptcp, which handles fluctuations of the link quality much better.

Used it a lot at work tho, for VPN redundency

I lived in a family apartment growing up, and we'd lock the door to the entire building at night when everyone was home with a sliding lock so that it could only be opened from the inside. However, that'd mean you need to ensure at least one person from every apartment was home, otherwise you'd need to go downstairs and let the others in in the middle of the night.

All the 3 apartments in the building were sharing the same wi-fi device, therefore I built a simple scanner to find all the devices in the network, connect them to the individuals I knew, and show the devices I found on the network in a simple website, which then I installed on my parents' devices as a PWA. The scanner would run in a Raspberry Pi I had lying around.

In the end it wasn't very reliable, the router kept failing occasionally due to nmap, and after a few failures we stopped using it, but it was a fun experiment for me.

Maybe not the most interesting but a CLI utility that would do 2 things (gaming related):

* guess the gameserver tick rate based on network traffic patterns between game client/server (cs:go for example) and display it in grafana

* collect keyboard inputs while playing and display them as a heatmap on grafana

All of this for no real reason.

I built my blog around fedora's extra nice pandoc markdown to html

It's not very fancy but it is for me. I know next to nothing about web/html and I wanted to do something myself than going with the really good ghost or other static blogging tools.

I made a gender swapping algorithm for my own use only. You put in any text and it outputs the exact same thing with all the genders reversed. Man to woman, he to she, Prince to princess, witch to wizard.

Then got a book deal to create a series of gender swapped illustrated books ‘Gender Swapped Fairy Tales’ and ‘Gender swapped Greek myths’

It seems like a simple enough task but gets complicated in weird ways. For example - his can swap to her or hers depending on the context. And her can swap to his of him depending on context.

The idea is to show the biases in the original stories that you are blind to because you’ve been reading them forever.

My first program was in C, input two dates in yyyy-mm-dd format, one by one,and tells the age. I used to call it Age Finder.exe Second version of it could work with dates entered in either order i.e. oldest newest or newest oldest.

Now I use javascript & html. The most used ones in recent past was my own timesheet log app. Html form submit data to Google sheet through Google script. Another page shows the monthly summary & details.

A telegram bot which logs my msgs as todo list to a Google sheet. I manually mark things done when done.

Many others at apps.bydav.in

I'm writing my own app for practicing the piano. The goal is to make practicing fun, while also making steady progress.

I'm not a good player at all, and I've struggled with practice for years. But I have no problems playing (practicing) difficult video games, that require a lot of repetition (think Celeste).

I think I've identified two major reasons why I never enjoyed it:

1. Classical music notation (sheet music) is just awful. It goes against most modern principles of easy-to-grasp information design. So I've come up with my own notation that is much easier to read and can be generated from musicxml files.

2. Practicing takes too much decision making and discipline. If you want to make progress, you have to constantly remind yourself to practice the parts that you're not good at yet - this is a surprising amount of mental overhead and requires lots of discipline. So the app I wrote listens to you play via MIDI and keeps track of which segments of a piece you're already good at, and automatically gives you those you still need to practice more - zero decision making required. You just play whatever the app gives you and after a few weeks/months you're suddenly able to play the whole piece.

The app is no where near ready to be shown, but I'm confident at this point that the concept will work.

I've been planning a longer write up on this for a while, if you're interested in reading more about it, please let me know, that would be very motivating :)

I build a "SaaS" wine app, for tracking wines in my cellar and for tasting notes as well.

"SaaS" in quotes since it runs in a small production setup with all the bells and whistles (ie. CI/CD pipelines, continuous releases, user signup etc.), but I'm the only user :-)

I'm a wine enthusiast, i.e. not a professional but interested enough to do a WSET2 in my spare time (I'll do a WSET3 when I find time some day). I like to/need to keep track of two things as part of my wine hobby: Wines in my cellar, and tasting notes.

Used to keep the wine registry in excel and notes in Evernote, however especially the excelsheet lacked features, like easy searches from a mobile device, and notes about the wines in my cellar (not tasting notes, as I have plenty bottles I need to taste but havn't yet, and I still need some notes on those to remember where the heck I got them from and why).

Also, WSET2 tasting notes a much quicker to do with the proper template, but copy/pasting text in Evernote became too annoying (again, phone).

So, I build my own app to have exactly the features and mobile friendly GUI I want. I'm the only user on purpose, because then I can keep building and changing features to be just like I want them.

Yes I know there are some "wine tracking apps" out there, like CellarTracker and Vivino, but they dont fit my needs. CellarTracker is closest to my needs but way too clumpsy GUI and not mobile friendly -- I don't have my laptop with me when I'm in the cellar to find a wine for tonight, I have my phone.

Will I every make up the time I spent building it in time saved compared to my excel/evernote setup? Nope, not even close. But it was a fun side project, and I like fiddling with the hosting/Ops part.
