Ask HN: What are some tools / libraries you built yourself?
Many times you just want to plug something in. PostgreSQL, Node.JS
Express, Java Spring, numpy, Three.js. There's many examples where
the already existing solution fits well. Sometimes that's not good
enough tho. What are some tools, libraries or services you built,
are they open-source and why weren't you satisfied using what
already existed?

| My first major Drupal project was for a local newspaper (now
| defunct... hopefully my site wasn't too big a factor in that) to
| which many writers were publishing articles, first to a "staging"
| site for sign-off to an editor, then to the live site. One of the
| many, many problems we ran into on that project (it was
| definitely a learning experience for all involved) is that the
| writers would link to other articles by finding the article on
| the staging site, copying the link, and then pasting that link
| into the article. When the article was published to the live
| site, that link was still linking to the staging site's URL which
| was inaccessible to the broader internet, so they were
| effectively broken links.
|
| To fix this I wrote a Drupal "input filter" called Pathologic
| which basically found all internal links in content and tried to
| rewrite them to point to the same content on the "current" site
| (which would be the live site after the article was published
| there). Eventually, after feedback from others, it could do other
| tricks like rewrite absolute paths to relative ones and vice
| versa (so your paths could be relative in a web browser, but
| absolute when the content was published via RSS feed or email),
| make sure http:// vs https:// was sorted out, and so on - broadly
| speaking, its goal was to make sure that links to internal
| content were always correct in all circumstances, and except for
| a few bizarre edge cases (there were always bizarre edge cases,
| though I'm glad to say they got exceedingly bizarre as the
| project matured), it met that goal. It became quite popular in
| the Drupal ecosystem and was my most successful open source
| project by far in terms of the number of users.
|
| Sadly, in recent years, I haven't been able to work with Drupal
| except for either small personal projects or projects that ended

| 2. bazel_compose [1]: A tool to wrap Bazel, rules_docker, ibazel,

|
| Stuff I built at college:
|
| 1. Parking Analysis [3]: My college had an _awful_ parking
| situation. I setup a cron to hit an undocumented API grab the
| number of spots open in the parking lots. I graphed those with a
| heatmap to find when our parking lot filled up around different
| holidays.
|
| 2. Butcher School [4]: A website used to "study" (memorize) the
| ARRL exam question set. It used some regex to parse the .doc file
| that is published by ARRL into it's json so anyone can create an
| updated set of questions. It also ran in local storage so you

| 1. Wallpaper adhesive (https://github.com/jacobmischka/wallpaper-

| multimonitor setups based on your displays ' resolutions. I use
| it every time I change my wallpapers, every month or so.
|
| 2. ics-merger (https://github.com/jacobmischka/ics-merger), a
| suite of tools including a webapp to merge separate calendar
| feeds together into a grouped feed, with possible subgroups. One
| can navigate through the subgroups, see event details, and

| feed. The webapp heavily relies on fullcalendar, but the added
| features aren't trivial.
|
| 3. Tea whistle (https://github.com/jacobmischka/tea-whistle), my
| second simple microcontroller project I made for my mother for
| her birthday because her teapot doesn't have a whistle so she
| kept accidentally boiling it over. It just polls the attached
| thermometer and beeps when the temperature is over boiling. She
| uses it every day and says she hasn't boiled it over once since!
|
| 4. inmytime.zone (https://github.com/jacobmischka/inmytime.zone),
| a simple webapp that allows you to create a URL that converts the
| time you give it into the local timezone of whoever is viewing
| it. It's effectively just a clone of https://everytimezone.com/
| or one of the many other similar tools, but much less busy and
| without ads. I let the domain expire a few months ago, so it's
| not currently available, but I just renewed it so it should be
| again once the domain servers propagate. Edit: Seems to be back
| up for me now, at least.
|
| 5. Gym notebook (https://github.com/jacobmischka/gym_notebook), a
| flutter app I made when flutter was still quite new to track my
| workouts using firebase for storage. It's quite rough around the
| edges, fetches data from the network way more often than

| A while back, I built a sync library for iOS storage <-> CloudKit

| has helped me grow the most (technically) as an engineer.
|
| - I built it because at the time, sync for iOS was a mess:
| Apple's original CoreData iCloud sync was very buggy and often
| failed to sync. An open source alternative seemed nice but poorly
| maintained, and I wasn't completely on board with the overall
| architecture of it. A paid library was great but also quite
| complex and I had no control over the direction, features, and
| longevity.
|
| - Apple released their own alternative recently, although it's
| only available on newer iOS versions. Additionally, I'm not in
| control of the CloudKit data schema, and I don't have the ability
| to add more complex sync features if needed.
|
| - underlying all of this: the need for control, reliability, and
| customizability.
|
| So, I spent a few weeks writing my own system. It works well and
| despite a few hiccups that I've resolved, it currently provides
| reliable, seamless sync for an app with millions of downloads.
|
| - My library is quite generic but I never open sourced it. It
| would be a nice contribution to the open source community, but
| I'm not sure I have time to consistently maintain it or review
| pull requests. I've considered it at times, but it's just never
| been a priority.
|
| - If sync ever goes wrong, I'm able to debug it and understand
| exactly what the problem is.
|
| - I can add features any time I like. I plan to do so soon to
| support a few things that even Apple's new solution might not
| encompass.
|
| There are quite a few downsides to it too:
|
| - I need to maintain it myself
|
| - It probably has had less testing than something like Apple's
| new solution
|
| - I've occasionally shipped a small sync bug, primarily due to
| lack of ability to test at scale
|
| Overall I think it was worth it, especially given that Apple's
| new solution wasn't available at the time. I learnt a lot;
| building a generic framework is a great way to grow technically.

|
| I have a ton more, but these are the two collections I more or

|
| To give an example of why I wasn't satisfied with the existing

| package repos and took literally hours to build on pretty good
| hardware (Rust is garbage in terms of build time, as much as I
| enjoy the language I almost never use it for this reason), and it

| in Go had similar problems so if I handed my nice single-binary
| application to someone to deploy on their own server I'd also
| have to hand them a zip file full of migrations and they'd have
| to figure out how to install a tool. Instead I wanted the binary
| to embed and be able to run its own migrations, so I wrote the
| library.
|
| For the 2FA library it was a similar story: all the existing ones
| I could find had the abstraction wrong, they just did TOTP or
| HOTP and didn't seem to realize that they were the same thing
| just with a different "ticker" function. Having a simple 2FA
| implementation where you could create a token and pass in a
| custom ticker (or of course the package would have the TOTP one
| pre-defined) just "made sense". Also, the others I evaluated
| weren't tested very well. I wanted at least a handful of tests to
| make sure the tokens weren't going to break the next time I made
| an update.
|
| Finally, for the HTTP router/multiplexer I wanted to be able to
| get the routes back out and match them to the URL components that
| matched various wildcards so that I could do easy normalization.
| Eg. if you had the route /u/{username string} and the URL /u/Me
| matched it, I wanted to be able to automatically redirect to
| /u/me. Most routers I tried didn't provide you enough information
| to do this (eg. if you had the path /user/User and you just did a
| naive find/replace that was more complicated than lowercasing,
| you'd accidentally change both when the route was /user/{string}
| so the first one shouldn't change). I also wanted typed route
| parameters to avoid the boilerplate of converting in my handlers
| every single time, and I wanted it to not have any ambiguous
| routes (eg. if I register /user/me and /user/{user string}, and
| the user creates a new account with the username "me" then should
