Kiwi Farms is Down After Cloudflare Boots The Site As a Customer

Kiwi Farms is an online forum where its users dox and harass trans people and women. Cloudflare used to provide the security service to protect the forum from cyberattacks. A week ago, Cloudflare initially resisted the pressure campaign to stop providing its service, saying its security service is a utility. But they now have switched their position.

I bet it wasn’t an easy decision for Cloudflare. But inaction is action. When we choose not to act when we see injustice, we become complicit. We must have our moral compass and courage to follow it.

If you are already obsessed with the wish, you are already much closer to realizing it than you would be. So a shooting star is a test, not a wish maker.

I got leadership training based on the famous personality test MBTI last Tuesday. I hadn’t had such training, so I was curious about how the MBTI results could help us work better as a team.

Unfortunately, I found the training reaffirm my skepticism over personality tests. The coach emphasized a few times that these test results are merely meant to drive conversations. But during the 4-hour exercise, those nuances were lost, and I felt boxed by the four letters of my MBTI test — some commented how someone got good scores, which upset me.

I understand that when at scale, we need a way to group many people because it’s impossible for one to understand thousands deeply. But we are talking about a dozen close colleagues that we interact with daily. We should rely on open and honest conversations, not these tests, to understand each other.

Exclusive: Leaked salary data show huge pay disparities at Twitter

Since money is finite, all compensation structures make trade-offs. Equal work, equal pay is a perfectly valid structure, just like the cost-of-labor-based structure. The companies should be upfront about their policies so that the job candidates can walk away if they don’t like them. Twitter’s failure here is not its compensation structure but its lack of transparency.

San Francisco’s Zuni Cafe removed tips a year ago. Despite pushback, it won’t bring them back.

Related to the article above, changing the compensation structure once you already have staff will always be painful.

What we see now is the mix reverting to roughly where pre-Covid data would have suggested it should be at this point.

Task-relevant maturity is a concept I am familiar with, but this framework gave me a practical guide on how I can delegate to my reports with different skillsets. The five levels of delegation are:

  2. Level 2: the report does the research and makes a decision, but the manager needs to approve.
  3. Level 3: the report does the research and makes a decision, and the decision is implicitly approved unless the manager intervenes.
  4. Level 4: the report decides without requiring approval and shares their decision with the manager.
  5. Level 5: the report makes a decision, and the manager does not need to know.
