I'm looking for work, please boost!

I'm a senior software engineer with 35 years of experience. I've worked across an unusually wide range of domains: mobile game backends, privacy-preserving data platforms, high-throughput COVID testing infrastructure, email and account systems, e-payment processing, job marketplace systems, and bioinformatics. I pick up new domains quickly and have a track record of doing it repeatedly. I understand how to turn business needs into engineering requirements.

I've worked remotely since the 1990s and can operate with minimal supervision. I don't need hand-holding to find the right problem to solve. Several of my most valued projects were self-directed: I identified the need, built the thing, and shipped it.

Some of the technologies I'm familiar with include: Python, Perl, TypeScript/JavaScript, Haskell, Go, C, Java. Postgres, MySQL, SQLite. Flask, SQLAlchemy. AWS (Lambda, S3, RDS, SQS, EC2). Docker, Git. Github and Gitlab.

I've also repeatedly picked up new languages and stacks as needed: Haskell for differential privacy research, TypeScript for a 24/7 AWS Lambda system, Flask for my most recent employer. I've become productive with new systems over and over, and I can do it quickly.

I'm also a published author (Higher-Order Perl, Morgan Kaufmann), longtime blogger, and conference speaker with a reputation for making complex ideas clear.

My résumé is at https://plover.com/~mjd/cv/Mark%20Jason%20Dominus.pdf

Today's #CloudOps / #DevOps challange: A developer who build a frankenstein #k8s implementation , has his last day before he drops a hearty fuck you to the rest of us and leaves the company forever.

My question

Can we just rebuild everything he built so its "built" the right way?

Am I that asshole for asking this?

Opinions.

Python Tip #158 (of 365):

If you had to choose, prefer automated tests over type annotations.

Of course... you don't need to choose. You can have both!

A type checker can tell you that your function returns the wrong type but it can't tell you that it returns the wrong answer.

Type annotations catch a specific category of bug: passing the wrong KIND of object.

Tests can catch that and more: logic bugs, incorrect output, mishandled edge cases, etc.

Not sure who decided it was a good idea to integrate Rust dependencies into Python modules.

Installing a 1GiB Rust package to build wheel is a waste of bandwidth and time.

Python Tip #154 (of 365):

Writing a type that's "this or that"? Use the | operator instead of Union or Optional.

"int | str" reads better than "Union[int, str]", and "int | None" reads better than "Optional[int]".

The old way involved helpers imported from typing:

from typing import Optional, Union

def parse(value: str) -> Optional[int]: ...

def normalize(value: Union[int, str]) -> str: ...

Dew Drop - June 1, 2026 (#4680)

dc is the RPN arbitrary precision calculator that's long been a standard on UNIX systems (but not actually standardized by POSIX)

Yesterday a friend was noticing how .. weird .. it is with fractions in non-decimal radixes. gnu dc is particularly spectacularly broken, while bsd dc is somewhat better.

gnu dc failing: 16dio 8k .02p (set precision to 8 places, input and output radix to 16, and print 1/256(decimal)) prints "0". Ideally, it would print ".02". bsd dc prints ".020000".

bsd dc failing: 99k 3o 1 3 / p (set precision to 99 places, output radix to 3, compute 1/3, and print it). Ideally it would print ".1" or ".1000..." but bsd dc prints ".022....21"

This is because internally all dc arithmetic takes place in decimal; additionally, gnu dc incorrectly counts how many decimal digits of precision are needed.

So of course .. I wrote my own incomplete dc implementation. It uses Python and infinite precision fractions. Only the very basic operations are implemented, but at least you can calculate in hexadecimal floating point notation and get accurate results.

pydc> 8k 16dio 
pydc> .8 .FFE *p
0.7FF
pydc> 1 3 / p
0.55555555

For now the code lives in my junk drawer and has no explicit license, but you can use it if you want. https://codeberg.org/jepler/junkdrawer/src/branch/main/bgj9ls82/dc.py
