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

It’s not wrong
A diagram labelled pride versioning

A version number of 2.7.123 is shown

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

A line pointing to the 7 calls it “default version. Just normal/okay releases”

A line pointing to the 123 calls it the “shame versions. bump when fixing things too embarrassing to admit”

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.

Gonna be a big week for this
Cartoon by Matty Lubchansky
First panel: one person says “wow did you hear about (redacted)? Turns out he’s a real creep” Second person says “that’s a bummer, I love his movies”
Second panel: first person saying “yeah they mean a ton to me too. Lots to reckon with.” A guy crouching in a black robe says “it’s not a big deal, actually, since I…”
Third panel: the guy dramatically casts off his robe and says “I… never cared for his work!” The first person kneels and says “oh my! A true genius!” while the second says “we’re in the presence of a visionary!”
Fourth panel: the second person says “what’s your secret?” and the guy, offscreen hands putting a crown and ermine cape on him, says “I’ve never liked anything, or anyone”

Echo Chamber Also: Aargh I posted the wrong image of this #PoliCartoon earlier today. Here's one with better panel four wording. Grumble, mutter... Blah blah blah patreon.com/barry
panels; each panel has a different setting, and with a different set of characters.

PANEL 1
A man in a polo shirt and jeans follows a woman down the street. The woman wears a hoodie and is walking a small dog. The man is talking cheerfully, doing the "explaining with my hands" palms up gesture; the woman is looking back at him and has raised her voice testily.
POLO SHIRT: So you see, when you "transgenders" insist you're women, that's you forcing society to along with your delusions. Let's discuss this.
DOG WALKER: LEAVE ME ALONE!
DOG (in thought balloon): Jerk!

PANEL 2
A woman and man are on a path in a park, the woman walking away from the man. The man is bald-headed with a van dyke beard. The woman has tattoos and blue hair.
The man has a friendly smile and has raised one forefinger in a "professor explaining a point" style; the woman is holding up a smartphone and speaking angrily.
VEST DUDE: I'm not saying men should hit women. But when men aren't allowed to hit women, men have no means of controlling crazy women. If I may quote Mister Jordan Peterson-
BLUE HAIR: DUDE! GO AWAY!

PANEL 3
A customer at a coffee shop, a blonde woman with curly blonde hair, is chatting with a friendly expression with the barista. The barista, who is Black and wearing cat's eye glasses, is waving their hands and yelling. The customer has a "Q," in the same font as the "Quilette" logo, on the back of her shirt.
CUSTOMER: There's no need to get mad. I just want to politely debate whether or not Black people have genes that make them stupid.
BARISTA: i'M NOT GOING TO "DEBATE" THAT!

PANEL 4
Three characters from the previous three panels - Polo Shirt, Vest Dude, and Customer - are sitting around a round table with coffee cups on it. They are all looking annoyed and unhappy.
POLO SHIRT: Woke "identitarians" are so rude!
CUSTOMER: They want to live in an echo chamber!
VEST DUDE: COWARDS!

Nice this about this place is that there are loads of people who I thought something bad had happened to but turns out they’re just not as addicted to the other place and have been here the whole time. It’s like re-discovering old movies or seeing an old friend for the first time in years
