About a month ago, I worked on a simple tree-drawing software. Existing explanations of the Reingold-Tilford algorithm confused me a lot. I decided to try to explain it by myself.

In my blog post, I really tried to cover every aspect and every step of the algorithm. Hope someone will find it useful.

If you have any ideas for improving my explanations, please share.

For the last 3 years, I have been working on a tool that helps me debug ASN.1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc tokens, and more), cryptographic operations, and JWTs. This app is available online; you can try it [0] (no sign-in/up needed).

First, this app supported only various cryptography operations.

Then, I started working with JWTs a lot, and I did not like jwt.io design at all. So, I made my own JWT debugger without ads, banners, and other crap.

And last but not least, I also implemented the ASN1 debugger over the years. The best feature is that you can edit the ASN1 tree directly on the page [1].

I'm happy that I wrote this tool. I use it often to help me debug my protocol implementations. I know that some of my friends use the JWT debugger and ASN1 parser from this tool. Maybe some of you will find it helpful too.

The app is open-source [2]. All computations are performed on the client side. Related submissions: [3], [4].

This December, I reached a huge milestone: I implemented ASN1 tree editing [1]. Now I can edit the ASN1 tree directly in the browser (read my blog post for more details: [2]).

I'm happy that I wrote this tool. I use it often to help me debug my protocol implementations and/or debugging. I know that some of my friends use the JWT debugger and ASN1 parser from this tool. Maybe some of you will find it helpful too.

For the last 3 years, I have been working on a tool to help me debug ASN1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc data structures, and more) and cryptographic operations.

A few days ago, I shipped a significant feature: ASN1 tree editor. Now it can parse and edit the ASN1 tree directly on the page. I found it very useful and may be helpful for others.

Follow the link and try it. Short manual:

* hold `ctrl` and click on the tree node title to edit;

* hold `ctrl` and move the mouse between nodes to add a new node;

* hold `ctrl` and move the mouse to the start of the node title to remove the node.

A complete user guide with images can be found in my blog post: https://tbt.qkation.com/posts/announcing-crypto-helper-0-16/.

Overall, this tool can also perform many crypto-algorithms and has a JWT debugger. But that's another story :)

I want the information to be structured. I want to navigate easily between persons, places, events, timelines, see interconnected items, etc.

The best option I found is logseq (https://github.com/logseq/logseq). Are there any better options? How do you manage your family history?

UDP: I just found Wiki.js (https://js.wiki/). It also looks like a good option.
