you know something serious is being cooked if you _need to_ remind yourself what a monotonic function is ;)

question: wouldn't it be - technically - more like the following? Considering that a slice could live in multiple places in parallel (shared database - to some extent at least, separate UI codebase, etc.) 1/2

Ptaszki ćwierkają, że powstaje nowy program. Przestrzeń do pracy już jest. Zebrała się też masa treści do przekazania Wam... bo i branża jest inna niż w 2021... Jeśli kojarzysz Architekturę Na Froncie (ANF), to spodziewaj się ogłoszeń 🙂 za jakiś czas 😉

Strong disagree. Depends on what we actually expect, what's the team, what's the culture etc. But still way too many devs are unable to communicate effectively with business. Stating that 90% is useless is purely ridiculous and a sign of ignorance. Unconscious incompetence in that area.

That's only a very, very small fraction of what LLMs can do if you prompt them properly We don't know yet how invasively the industry will change.

Now it's our job (the community) to raise the interest trend. We've seen @t3.gg, @adamrackis.bsky.social and others being really positively surprised with recent @angular improvements. #Angular needs more of this 👊 But ALL tools are decreasing in this area. Take a look at Qwik...

Tomasz Ducin @ducin.dev · 17/12/2024
the positivity factor is increasing. Steadily. That's a great job done! Congrats to the #angular team and the entire community!

state of js results are out When it comes to #angular, I'd say the most difficult part (shifting the trend) is already done. Most of the stats are increasing (except for awareness which is 99-100% already). If the trend continues, #angular would regain no.2 from @vuejs.org

Here are polish Software jobboard stats (number of offers) month by month (curated by Mateusz Jarzębowski-Bownik). Plus my "forecast". I'm not saying it's a bad idea to hire juniors. But, as I wrote in the post below, I can't imagine this trend to change, out of a sudden. Mostly because of AI.

Someone was waiting for my #aDDDvent post today (day 6). That's a great sign! The post won't be published today. 🫣 Wait till tomorrow 😉 Today I spent "the Santa day" 1:1 with my 6yo traveling and having fun. First things first 🥰 #DDD #DDDesign

The biggest "problem" with DRY is people thinking DRY is about lines of code. It's not. DRY is about knowledge. Enforcing few-liners not ot be repeated _can_ be counter-productive. Still, the point is not to copy/paste for the sake of it. DRY/antiDRY is a false dichotomy.

#aDDDvent: day 1 📆🎄 If you think you're doing DDD by following a certain technology/framework/toolstack/pattern/etc, you're doing it wrong. 👉 DDD is not about technology 👈 DDD is about collaboration and communication. Full writing ✍️ below #DDD #DDDesign #react #angular #vue #frontend

Playing with imagen 3. The best thing is that it's free. But it seems so stupid that it really challenges my patience to generate what I want. Far from being very useful. Anyway, That's the best picture I managed to generate. I wanted a totally different thing, but colors are nice. 🤷

Yesterday we've had a fantastic domain exploration (as a pre-training rehearsal) with @raimeyuu.bsky.social. The pic is in PL but anyway, if you're into #DDDesign, give Damian a follow. Learned a lot from him, especially applying heuristics.

Does it mean you become a fanatic who is overflooded with those abstract concepts? Not that much 😛 - the point is - you split your software by semantics. In a totally different way, that scales with business complexity. Picture just to draw attention 🥲

"Practicing #DDDesign means putting business above technology"... - okay, but this could mean totally different things to different people. What's the point of all these "domains" et all? ❌ It's not about using fancy, shiny names (and #DDD has quite some of these).

DDDear FrienDDDs together with @raimeyuu.bsky.social we've asked AI to generate a bounded context map for a roughly described medical domain. Wanted to make it good (!) and - after turning it into a .cml it has spit out... this. We're safe 😎 #DDDesign
