(Shallow?) Reinforcement Learning

Kind of... Spent a while debugging an issue where the client was convinced he could not schedule new appointments in the system on the 29th.

It turned out he had set another setting incorrectly which was causing the appointment never to be valid.

But the rarity of the date let me wonder in the wrong direction for a while...

It seems the authors did not find evidence of a "pink tax":

"Finally, while our findings do NOT support the existence of a pink tax as conceived by regulators, a more expansive definition of the pink tax could include differences in markups across men’s and women’s products."

"...our finding that women’s personal care products are not systematically more expensive than substantially similar men’s products calls into question the role of government intervention to reduce the pink tax."

0. Use GIT.

1. Add a staging environment.

2. Add a CICD.

3. Add tests. Start by easy ones (new features) to get team used to writing them. Then important flows. If your team doesn’t have the bandwidth hire a contractor. Ex: https://avantsoft.com.br

4. Choose a part of the code the warrants being the first to refactor. Balance easiness with importance.

5. Define a better structure/architecture for it.

6. Refactor.

7. Repeat from 4 as many times as needed.

Also, consider micro-services on new features… may be an alternative to full rewrite.

The big question to me is: At what level of the tech stack should moderation happen?

Should it be done by the ISP? By the IaaS? By the software provider? By developers?

Ideally, moderation would occur at just one level. That way, there are less avenues for abuse to occur. Leaving moderation rules vague may lead to some services that could be beneficial (whistleblowers, etc) to be easily taken down.

Productivity porn 4 years ago

"Productivity porn is anything that after having been consumed makes you feel like you were productive when in reality you didn’t actually do anything." - Interesting definition.

Is everyone an employee or are there contractors as well? Are there managers? how large is the team?

For smaller teams (sub 10 people), I find that having 1 daily informal standup and having the leaders make themselves readily available for answering questions is often sufficient. The key is often for leadership not to block development (so no long review cycles for PRs or long time deciding on details that subordinates need to accomplish their work).

I would recommend talking to a professional. There are psychologists and equivalent professionals that specialize on this and they may be able to provide you some guidance.

Not sure this helps but believe in yourself. The fact that you are even willing to talk about this already shows a level of self realization that few are able to achieve.

The article makes some good points.

Having lived in over 4 countries I can say the United States is by far the most bureaucratic when it comes to immigration. Processes are long, complex and expensive. Often requiring multiple rounds of paperwork or even quarterly submissions of additional documentation (such as with STEM OPT). It definitely discourages people like me (PhD in engineering + entrepreneur) from staying.

Even though the graphs do show some correlation between politics and media trust, I believe there may be other factors at play here. For instance, the need to make headlines ever more clickbait may also be eroding trust. Since the body of the article and the headline often don't agree.

Is DevOps Dead? 4 years ago

I wouldn't say that DevOps is dead. Just that some companies can survive without it. It is the type of thing that is good to have. Not absolutely required. You tend to miss it most when things go wrong lol
