@alina_yurenko How do you deal with observability of GraalVM apps? Is there anything specific there?

What a native AI application can look like with GraalVM: — starts and connects to a database in 111 ms ⏱️ — easy deployment unit of 130 MB ☁️ — max RSS ~118 MB 🚀

@shipilev Thank you for your service!

Spent about 5 days to figure out about 5 bugs in the Hotspot guts, based on understanding of subtle invariants that missed the asserts. But yes, do tell how easy it is to build a production quality compiler :) Hint: building one is easy, debugging one is full-time job.

@asmah2107 Approximate the route and send updates only in key point of it like intersections.

Quick question : You're building a food delivery app. App tracks 100,000 drivers in real-time. Chaos. Driver's phone sends GPS coordinates every 4 seconds. Drained phone batteries, your servers overwhelmed 🥵 How do you fix this ?

@soul_surfer78 @hackaday here you are github.com/Mentra-Communi…

@hackaday Nice where the GitHub link

@marcinmoskala Should we use awaitAll in that scenario?

I just hate when people do async {}.await(). This makes no sense whatsoever. Why start something asynchronously if you await it immediately? You should separate asyncs from await.

@jmcphers @ericmigi @Pebble And you can switch to the next track without looking on it

Hey look, a smartwatch that doesn't need charging every day, reads better outdoors, doesn't send data to big tech companies, and has an open source OS! This is so fun. Thanks, @ericmigi, for bringing @Pebble back.

@megaconfidence @Pebble That's actually traditional smartwatch. Where was apple watch in 2013?

It's time, say hello to my @Pebble If you're not into traditional smartwatches, you'll love them. They are so quirky and hackable 🤓

@ktdotacademy Recently i've tried compile time injection via context in kotlin. And I really enjoy that style. Can't wait this feature to become stable!

The way how static dependency injection works is actually very simple, and I can explain it in two minutes! Let me show you 👇🧵

@hamen @lufthansa @DB_Bahn You can also stuck in 5 hours traffic jam on an Autobahn!

We eventually got home last night: 15 hours to go from Berlin to Turin. We had the fortune to experience @lufthansa cancelling flights from BER, @DB_Bahn cancelling and rerouting trains for Frankfurt. What a nightmare day! What an incredible marketing campaign for cars!

@ericmigi Would be just amazing if Core 2 Duo has hear rate sensor like Pebble 2 had.

Got the first bigger batch of Core 2 Duos in the mail! 150 more next week. Also switched to testing a black C2D...still prefer the white though

@zsmb13 Initial setup. Each time I try to generate new empty project and make "Hello world" it fails. But maybe it's me :)

Quick request for feedback: what's your number one problem with using KMP today?

@andraskindler Is that your new startup? :)

@intellijidea Async IO to complete

In the life of a Java dev, waiting is inevitable. ⌛ What are you usually waiting for – builds, bugs, a miracle... or for AI to finally finish generating the code? 🔥 #Java30Countdown #Java30

@intellijidea It depends how you run this program. "--XX:AutoBoxCacheMax" flag alters that behavior.

This code outputs 'Not equal', since x == y compares the address of the instances referred by the variables 'x' and 'y', not their values. Use .equals() if you want to compare their values.

@intellijidea It depends. If you pass -XX:AutoBoxCacheMax=1000 option to your app it will result to "Equals"

What do you think is the output of this code – “Equal” or “Not Equal”, and why? 🧳 #Java30Countdown #Java30

@kotlin It's good. But I find it not that easy to verify request for example or configure several responses for more complex scenarios.
