hackerer-news VS rgca

Over the years, I've written many apps and utilities for myself or others (that didn't end up get used). These are the interesting ones I remember. Many not quite complete/usable. Other than hackerer.news none of them are 'up' and running. Some have and others haven't been published as opensource.

- https://hackerer.news HN viewer (source[0]): I use daily so I can see today's top stories in reverse chronological order with mainstream topics sorted to the bottom.

- qwickly[1] keyboard layout: I use all the time as an easier to learn and more comfortable to type than Colemak/Tarmak

- safeql[2]: Java type-safe SQL expression composer that reduces constant expressions and eliminates N+1 queries loading associations by always operating on set relation or array of models.

- moja[3]: Composable computation pipelines for Java: Async, Lazy, Option, Try, Result, Multi (List), Stated, Reader, Logger, Writer.

- gitgrep.com[4] Opensource SaaS version of etsy/houndd (now called hound-search).

- statuspages.me: Status page aggregator with dynamic javascript for scraping each source using selector expressions.

- movies to watch aggregator: with links to sources to watch. It was hard then to get 3rd party deep links into streaming sites so included some torrent links. Got a DMCA phone call, so took it down. Combined thumbnails, summaries, actors(?), imdb ratings, links.

- java2cpp: Translate a moderately sized java app with test suite to c++, not 100% required final manual fixups.

- swift2java (or maybe it was java2swift, it's fuzzy now): translate Swift to Java obviously, using ANTLR4. Not 100% required final manual fixups.

- gui2log: to make an ASCII rendition of on-screen GUI widgets into an application log file when form submitted, so users couldn't complain that they saw X, but got Y.

- some basic stats/ML algorithms: k-nearest neighbour, RNN back-propagation, etc?

- Java in-memory DB: Small SQL-like memory tables with indexing/searching.

- wwwsqldesigner: This exists as opensource and I extended it to infer foreign key relationships based on naming conventions used in a MySQL schema. It was great for zooming around a large ERD.

- tracelog: combination of microservices parent/child span logging and generated high level events shown as a sequence diagram. Integrated with Loggly for full/verbose logs of selected high-level events.

- pcl2bmp downscaler: Reduce high resolution HP LaserJet (PCL5) printed to file to lower resolution bitmap pages for screen display (before retina DPI was common). It aimed to shrink same-color areas and preserve black/white transitions while reducing.

https://hackerer.news viewer that shows stories by day so I don't see yesterday's stories today interleaved with today's and avoid the slot machine dopamine hits.

Shameless plug, there's also https://github.com/linsomniac/rgca

I've been using it at work for the last year for our certs and it's been quite nice. It can do pre/post hooks as well, so it directly commits the updated CA serial files to our git repo.

I built a TLS certificate tool targeted towards my company usecase for internal certificates (developers, OpenVPN, internal certificates): https://github.com/linsomniac/rgca

It's big features are that the cert generation can entirely be controlled from the command line, config, or environment, or any combination of the above, and it has tooling for the situation where I have an existing cert but want to add or remove a name from it. It also has pre/post scripts so I can have it do things like add it to the Ansible repo, vault encrypt it, and commit it. Beats the 10+ year old script that didn't work with Subject Alt Names.

Over the last year I've written several CLIs in click and typed and settles on typer because there's a little less repetition. Typer let me do some really nice things in my certificate generation tool like chaining multiple config files, the environment, and the command line to create certs. https://github.com/linsomniac/rgca

I've always found the OpenSSL tools painful for managing internal self-signed certificates. At work we make fairly heavy use of them, and are starting to make even heavier use. Our use is more than EasyRSA can provide. So I've been working on a new CA tool:

https://github.com/linsomniac/rgca

In a nod to OpenSSL config files, it can take almost all values: from the command line, from the environment, or from one or more config files. It also allows "pre" and "post" commands so you can run a script after generating the cert, for example for server certs I have a "post" script that will copy it into the appropriate location in the Ansible repo, encrypt the key file, and commit it all.

I still need to implement a "renew" which will take an existing cert, update the expiration date, but also allow adding/removing SANs, possibly other features. But I've been using it to generate all our certs recently and it's working great.

At work we use self-signed certificates for internal and developer use. I inherited some scripts that wrapped the openssl CLI but weren't supporting new uses like the prevalence of Subject Alternatives Names. So I reimagined it and have published what I have so far here: https://github.com/linsomniac/rgca With an appropriate config file, the typical use would be: rgca ca new example.com rgca cert new user1.example.com rgca cert new --san test.example.com --san test2.example.com user2.example.com Basically everything can be configured by settings in (possibly multiple) config files, environment variables, and CLI options. Expected use is that things like the subject values (country, state, locality, email) are set in the config file, so the CLI can be short. Instead of: rgca cert new --C US --ST Colorado --L Fort Collins [...] It should be compatible with existing CA setups with OpenSSL CLI tools, it writes the "serial" and "index.txt" files. Looking for feedback on the direction this is going in. Thanks!

It can also run pre and post scripts to, say update your serial/index in git, and deploy keys to the server, say you are rekeying every 30 days...

Interested in feedback.
