I built my own Replit-like web app called Dock'n'Roll powered by Docker to write quick web apps in any language and quickly host them in isolated containers on a subdomain of my domain (*.varunbiniwale.com)

Using it, I can quickly build up tiny apps and have them online reliably, eg. I use https://yourip.varunbiniwale.com/ while looking for vulnerabilities.

I protected the admin panel for `dockn` with my own nginx auth proxy (https://auth.varun.ch), which lets me control user account access and rate limiting for all my self hosted websites in a central place.

My profiling tool: github.com/lally/ppt

I needed really high quality performance telemetry ("profiling" is a mixed choice) for my PhD. You specify the payload type in an IDL and it generates types and transport code. Fill in a struct and hit save(). If the process is being observed, this'll copy the struct to a lock-free ring buffer that the observer injected in. Includes CPU performance counter support.

The chore wheel [1], which my wife and I used to run on an old iPad to track evening chores. It uses local storage for recurring chores and one-off reminders. We tried a bunch of other tools but they were all too full featured or slow to ooperate. It replaced a paper list.

When debugging network issues I realized I was going back and forth between my computer, router, and cables under the desk. I created an audible network check [2] so I could just listen to hear the status.

Earlier quoted context omitted.

> full text tabs forever [1]: chrome extension to provide full text search over web pages I've visited This is amazing . But wouldn't this extension end up taking up a massive amount of space? Does it index text which is fetched and hydrated after page load? Also, does it strip HTML from the text so that text like this can be searched with exact phrase matching? Is the source code for fttf available? I'm sure you're…

It doesn't take up too much space. Currently about 70mb on my system. It will grow over time of course. It used a distilled version of the web page, i.e. "reader mode" and indexes that rather than the full HTML. So yes it indexes plain text only and, in theory, ignores headers footers and other non-interesting parts of web pages. Anecdotally I find it invaluable for finding a web page I know i've seen but can't remem…

If the publication date (Nov 30) is an indication of how long you've been using it, it's not exactly lightweight :P

> It's not open source as of this comment, but the plan is to open source it

Might be really useful with some configuration around which domains to archive; I may contribute (or fork if you're not accepting contributions) if it is released under an OSS license

> It's also not minified or obfuscated, so the source is "available" in that sense.

Amazing!

Just some little perl scripts. One to randomize my playlists, while keeping all movements of a classical piece together.

A web page to record and graph my asthma medications and peak flow numbers. Impressed my doctor, if nobody else.

Another web page that started as a tracker for all the new beers that kept coming on the market here in Denmark. That evolved to tracking all my drinking and restaurant visits. Been using it since 2016, and improving it along the way. Now some 3k lines of more or less readable perl.

I have something of an obsession with being able to search my digital history. To this end I've created a few projects which I still use almost daily: - full text tabs forever [1]: chrome extension to provide full text search over web pages I've visited - browser-gopher [2] (formerly browser parrot): collect browsing history from all browsers - prompta [3]: a ChatGPT UI with full text search and some other niceties […

I really love full text tabs forever, but as another commenter noted, it’d be good if it was open sourced to make sure it’s not sending the data to the devil.

Thanks for sharing!

I've written a podcast ad blocker. I'm not based in the US but listen to a few podcasts from large US-based networks. They don't have any ad inventory to sell so instead they fill the slots with ads for other shows on their network and I end up hearing 7 copies of the same ad for the same true crime sludge in each podcast episode. It works by fetching the XML feed, downloading the file and applying an open-source aud…

Do you mind sharing the code for this, or point me to the audio fingerprinting solution you use? I'd love to replicate this.

https://github.com/AddictedCS/soundfingerprinting Is the library. It was the first thing I found and it seemed to do the job. I’m not a .NET guy so it’s implemented as a CLI tool that takes a wave file as input and spits out a list of timestamps.

Sharing the code would mean getting into the business of publishing an ad blocker which is not something I personally have the bandwidth for. It’s also far from my finest work, being something that I banged out in a weekend. Happy to answer other questions about it, though!

I came to Tokyo more than 10 years ago when there were still feature phones. The email app was fast and easy to use, looking up train connections through the pre-smartphone WAP browser was slow and a pain.

I was looking up train connections so often that this became too painful and built an app that would accept from/to train station pairs via email and send you back the best connection.
