Code Modularity and Clear Boundaries Importance It seems everyone has an opinion on how AI will shape our lives and our profession as software engineers. I'd like to share my view on a specific topic: modularity, encapsulation, and proper software ...

You think #ai will write all the new code and make all the necessary changes in existing codebases soon? If so, the way we design and structure our apps today matters even more than ever. I wrote my thoughts about that on our @softwaremill.com blog softwaremill.com/code-modular...

Yeah, caching which was meant to speed up compilation caused the opposite effect :D Who would have thought that blindly throwing in the cache with defaults may cause issues. Better cache management with removal of unnecessary trash was the major trick here.

Shaved off some #ci build pipeline time from 22mins(!!!) to 5 mins. Still, there is a room for more improvements to go even faster sure, but sometimes simply taking care of relatively low hanging fruits improves things a lot and gives good enough ROI

Why and How to Bridge the Gap Between Business Stakeholders and IT IT departments can speak your language and suggest new or improved ways of handling specific business cases. The only requirement is to bridge the gap between them and stakeholders.

#IT depts seen as being disconnected from the “real business,” labeled as ineffective “cost centers” within companies? Or engineering teams viewing business people merely as a “source of requirements”? I wrote a piece on that on @softwaremill.com blog softwaremill.com/bridging-the...

Dzień po konferencji
@boilingfrogspl.bsky.social miałem wielki zaszczyt pojawić się w studiu u Mariusza Gila jako gość podcastu Better Software Design. Porozmawialiśmy o gwarancjach i sposobach dostarczania wiadomości w systemach rozproszonych. Zapraszam! 🇵🇱 bettersoftwaredesign.pl/podcast/o-do...

Heading back home after the 10th edition of the @boilingfrogspl.bsky.social conference. The event continues to raise the bar year after year. I had a really great time. Thank you to all the fantastic people who attended my talk and with whom I had the pleasure of chatting afterward!

Exciting weekend ahead! Getting my stuff packed for the awesome @boilingfrogspl.bsky.social conf. In the morning I'm gonna talk about message delivery guarantees. Can't wait to meet all the cool people there! I'm also having one more gig there in #wroclaw on Sunday, I'm super pumped about!

Great example of why only "static" analysis of your #softwarearchitecture sometimes pushes you in the wrong direction and why in-motion/runtime analysis gives you a bigger picture and allows for more informative decision making process architectelevator.com/architecture... from Gregor Hohpe

Naaah. I'd personally hire you just to tell me a story how did you come up with this :D

Yeah, I can fully understand this. Would be ideal to know foundations backing his claim in that topic to get bigger picture. Currently all we have is a single bold claim thrown into the internet - what can go wrong :D

Because these are in no way the "absolute truths" :) Just a bunch of opinions of a random internet guy that happen to overlap with my takes these days quite a lot. Also it simply all depends where you sit claiming these.

Well, remember these are not "ultimate truths" but just opinions of a random guy on the internet. It's a bold statement, I agree but I also think there is little something to that IMO (and yes, I used to do frontend quite a lot back then but no longer enjoy it).

OMG, triple-yes to so many points from these lists chriskiehl.com/article/thou...

I must confess here, it's like with bash scripting for me. Every time I need to use these magic spells I have to re-learn them from scratch, googling or now chatgpting it all. And I promise myself I'll learn it by heart one day... It's still not the day though :D

Fellow introverts, not all is lost for us! Study shows that introverted leaders led more successful teams when intuitively handling large amounts of information. expertfile.com/spotlight/10...

A while ago @michal.ostruszka.me shared a talk by @marcbrooker.bsky.social on resiliency strategies used in the AWS SDK.

Some weeks passed, and now we have an implementation of "adaptive retries" available as one of the retry patterns in Ox, thanks to Kamil Lontkowski.

Eventual consistency IRL :D

Canva incident report: API Gateway outage - Canva Engineering Blog An incident report for the Canva outage on November 12, 2024.

Good postmortem writeup about some #canva outage. Thundering herd problem caused by unfortunate timing of CDN issue, all this combined with unwanted blocking I/O ops in Netty-based event loop API gateway code when handling the herd requests www.canva.dev/blog/enginee...

#chrome #bravebrowser tip that makes dev life a tiny bit easier: automatically open devtools in child tabs if parent has it opened. Spent a while looking for it, not well documented. On macOS: open -na "Brave Browser" --args --auto-open-devtools-for-tabs"

Have you ever wondered how @bsky.app works under the hood, where it differs from others and what's the buzz about its decentralized architecture?

Cloudflare incident on November 14, 2024, resulting in lost logs On November 14, 2024, Cloudflare experienced a Cloudflare Logs outage, impacting the majority of customers using these products. During the ~3.5 hours that these services were impacted, about 55% of t...

TL;DR; Safety nets may do more harm than good if left unconfigured. Test your failsafes folks, review and tune to keep them in sync with changing landscape (load etc.). Interesting review of recent @cloudflare.social log loss. The numbers are impressive blog.cloudflare.com/cloudflare-i...

Complexity rises, not from parts' number or size,
It's interactions among them, where troubles can rise.
While linear ones are simple and clear,
With complex interactions, failures loom near.

— Epigraph to Chapter 3: Complexity and Interactions of Balancing Coupling in Software Design

Test passed. Now you can refactor :)

Noob question (as I'm not a fan of mechanical keyboards due to exactly that): do they still click so frickin' loud as they used to years ago? Is it still "a feature" or is it improved with just the feel retained these days?

I'm telling you, #IT people really love deadlines. I just submitted a talk proposal for @l8conf.com. Guess what's the CFP deadline 😅?

I finally gave it a go today, well conducted and enjoyable talk! Apparently it's not all roses working on opensource and being solopreneur. Who would have thought :) Also I somehow expected slightly different answers to some of the questions at the end :)

Masz "skilla"? Dołącz do nas w @softwaremill.com!

Did you just implement push based, distributed CFP deadline reminder in one bsky message?

Not a single word about tools, languages etc because they usually don't matter much. One may decide to only use set of tactical #ddd patterns just to organize the codebase. That's fine too, that's what @vaughnvernon.bsky.social calls DDD-Lite, but there is waaay more to #ddd than that

Stop Pretending To Do Domain-Driven Design It doesn't matter how many entities, aggregates, factories, services, and repositories you have. That's not domain-driven design.

It reminds me this recent gem www.jamesmichaelhickey.com/stop-pretend...
