The headline and article try to bias and frame the story to make people question: "Is OpenAI snitching on me?" In reality, Uber records and conflicting statements incriminated him. He seems to be the one who provided the ChatGPT r

I'm sure the OP means well, but I think this approach is misguided. It comes across as self-centered rather than supportive. You might get a polite "thanks" in response, but I doubt it will be genuinely appreciated. If you ca

It's still around, but the hype has faded. Users discovered numerous issues with the project and began abandoning it. I remember one month when everyone was all, "LangChain is the future," and another month when the sentiment

As a JS developer for over 10 years who has seen multiple hype waves, here is my advice: You don't need to ride the first wave. You can wait until technology matures and see if it has staying power. For example, React and TypeScript we

I wonder if they do a routine map of the delivery area (with a Lidar plane) so they have a high-resolution scan of the city for better pathing. But they didn't expect something like a crane that could be assembled so high and fast to b

I was in your shoes when I was 17. I built a social app to replace Orkut's communities (which Google bought and killed) and a chat app before Discord took off. Some advice: - If you want to improve as a developer, keep building feature

I should have added that to the post, but we verify by running a full test suite in a cron job, so if a bug slips, we will know. The full suite sometimes breaks, but these are due to changes outside of PR (e.g., a vendor goes down).

Thanks! > Are you seeing a lower number of production hot fixes? Yes, with E2E tests in general: They are more effective at stopping incidents than other tests, but they require more effort to write. In my estimation, we prevent about 2-

We still run E2E tests before deployment, but running them on pull requests also eliminates the question: "We want to deploy, but have a bug. Which PR caused it? and how do we fix it?" This approach essentially saves you from havi

by jampa 1y ago
I think you might be confusing end-to-end (E2E) tests with other types of testing, such as unit and integration tests. No one is advocating this approach for unit tests, which should still run in their entirety on every pull request. Runnin

I think not hiring juniors is a tragedy of the commons situation. It started before the AI boom, during COVID. It's not tax-related as people claim here, since this phenomenon is not US-only. The ZIRP era made companies hire people as

Unless something changes in the underlying infrastructure, most packages don't need active maintenance after achieving their objective. If there is a major change (e.g., Python 3, React Native new arch), they are replaced/forked.

I felt that, too. It turns out I was getting 'too comfortable' while using CC. The best way is to treat CC like a junior engineer and overexplain things before letting it do anything. With time, you start to trust CC, but you shou
