Thank you. So many people on twitter suggesting that it’s all his fault for letting AI run with no checks but actually he’s an idiot for not properly managing his IaC state

Just updating my calendar and Shrove Tuesday πŸ₯ž, Lunar New Year 🧧, and the start of Ramadan πŸŒ™ are all set to fall on the same day this year (February 17th), which feels pretty special.

Same with Google docs. I’m sure @cassidoo.co did a video suggesting using different shades of background for this as well

Round my way they used to use plastic bags for the body and head - maybe since you can’t get them anymore, bags for life just don’t work as well?

Works great as a CV builder? People think they need it to be β€œweb scale” or β€œcloud agnostic”?

Admittedly the second is partially correct in that it’s more cloud agnostic than managed services.

What’s the difference between being over for business and working remotely whilst you’re there?

less than five hundred years ago even the most powerful monarch was at the mercy of childhood disease and weather. now we can do literal concrete things about both and are in fact actively choosing to die of childhood disease and weather

I wonder how much of that is the useful stuff in powershell has been around for a while and is well before any cut off date for the AI models

What do folks here think? I suspect that the mindset on bluesky is a bit different from X (report for reach please)

Even if this is a joke, this is the reason I’ve avoided using an AI tool in my IDE or for coding in general. I’m worried I’m not going to learn new things

I posted this on the other place and I’m interested in seeing the responses to the folks here for comparison:

In response to someone saying that that they’re too lazy to look stuff up and they’re getting to the point where they’re using Cursor and not even reading the responses, I wrote:

A diagram labelled pride versioning

A version number of 2.7.123 is shown

A line pointing to the 2 describes it as β€œproud version, bump when you are proud of the release”

A line pointing to the 7 calls it β€œdefault version. Just normal/okay releases”

A line pointing to the 123 calls it the β€œshame versions. bump when fixing things too embarrassing to admit”

american masculinity is so amazing. caring about clothes as a man apparently makes you "gay" but our position on geopolitics totally depends on whether you wear a suit

Check go mods as well if you use that kind of thing - even if you don’t write go but use β€œgo install” for some software

If you are not fully aware of the downsides of using Kubernetes and accept them as necessary due to your organization's scale, then you do not need Kubernetes and should instead use a managed container service.
