This is the web page of Joe Mistachkin.

I firmly believe in and adhere to the ACM Software Engineering Code of Ethics.

Here is a partial list of my interests and/or expertise: automation, cryptography, databases, developer tools & SDKs, distributed systems, (Internet) security, public key infrastructure, runtimes, sandboxing, scripting languages, testing, and virtual machines.

Here is a short list of keywords for the search engines: Tcl/Tk, Eagle, SQLite, System.Data.SQLite, Fossil SCM, Comdb2

About Me

I have a strong preference for information reuse; therefore, instead of duplicating "profile" content here, please refer to my page on the official Tcl/Tk wiki.

I support open source and have been deeply involved in various communitities for most of my career.

I have written some very advanced systems.

Here are a couple of my current "side projects":

Eagle: Secure Software Automation
Harpy: Secure Software Provisioning
SQLite Encryption Extension for System.Data.SQLite
Enterprise Key Management plugin for System.Data.SQLite

Contacting Me via Telephone

Please contact me via telephone if any of the following conditions are true:

I can be reached at the contact number associated with this domain.

Unfortunately, the WHOIS database now appears to be somewhat unhelpful for obtaining domain contact information.

Therefore, as an alternative reverse Turing test, please visit the Eagle Live Language Demonstration and follow the directions contained in snippet #11.

Secure Communications

Please use Session for voice calls (or text messages) that require security. My current Session identifier is:


For another layer of security, please consider using my OpenPGP public key (shown below) to encrypt all message payloads before sending them with Session.

I can still be reached via Signal as well; however, I now have a strong preference for Session.

Please use my OpenPGP public key for messages that require layered security.

The fingerprint of the public key should match the following:

C3C7 5138 83EE DD3A ED1F  E425 502C 96AF 495D C2D9

The SHA-1 hash of the downloaded public key file should match the following:


Contacting Me via Email

I can be reached via email by concatenating the following strings, in order:

  1. My first name.
  2. The @ symbol.
  3. My last name.
  4. The string .com.

There are no other public email addresses for me.
