Build a Flutter Expense Tracker with Advanced Transaction Features.
My elevators on the horizontal stabilizer (my black-gloved hand is touching them) need mass balance to minimize flutter at high speed.
My rudder, also in 1st photo, has the mass balance built into it. There is not enough room to do that for the elevators.
Where to put the mass balance?
The oval hole at the bottom of the vertical fin is an access/inspection point. It goes there.
Note: when the mass balance is 'far away' from the control surface, the control system linking the two should have as little slop (backlash, hysteresis) as possible.

The counterweight is lead shot in thickened epoxy. (I won't melt and cast molten lead!)
The density of lead shot?

Sharing our experiences is important to us! 
That's why this week, we're telling you about our experience developing the #PeerTube mobile app.
Today, we published our second and final blog post on the subject! By reading it, you'll discover the steps that made us sweat when trying to publish the app on the Apple Store. 
Wicklow, the developer of the #PeerTube mobile application, has written a nice blog post detailing his technical choices (#Flutter, #Dart, dependencies, etc.).
Take a look! https://joinpeertube.org/news/flutter-app-dev-feedback-1
Last night I thought I'd check out Flutter/Dart and after a few hours of playing around this ugly-ass prototype of an Android client for @readeck fell out. I know there's already one in the making but that's about as functional as mine so I think I might just keep working on it (unless I get bored) and maybe even finish it.
Glider rudders need a counterweight to be properly balanced.
What?! Aren't airplanes supposed to be light? Why add more weight?
This reduces the tendency toward flutter. (Any airplane, at a high enough speed, will flutter. Don't go that fast.)
An unbalanced rudder (or any flight control surface) will be prone to flutter at slower speeds.
1st photo shows the rudder on a bracket that allows the rudder to freely pivot. (See alt text for more discussion.)
2nd photo shows rudder oriented normally. (See alt text)

Imagine being the test pilot here...deliberately gaining speed to get (just barely) into the flutter regime...surviving, and learning.

I am not using a control horn to reduce the control pressure I feel on the rudder pedals. Modern gliders typically don't need that.

It legitimately angers me that Google claim any sort of robust #accessibility support in their half-baked #Flutter UI toolkit. From the need for users to manually enable an accessible mode in web apps, to the use of accessible names to convey role information on mobile, to a borderline unusable keyboard experience on Windows, it is a rotten mess throughout.
lol, this started out with me thinking this will just be a simple find/replace...let's just say I was wrong.
Totally worth it though for the learning and for the result.
The #LinuxAppSummit is just around the corner!
April 25–26

Explore exciting sessions on #Flatpak, #GNOME, #Flutter, #KDE, #AI integration, #GTK & more. https://linuxappsummit.org
I've been teaching "Introduction to #Mobile Development" for 4th-semester students over the last years.
I've used #Android and #Java but got quite disillusioned with the Android development ecosystem (to call it a moving target would be a bit of an understatement).
So this year I tried out #Flutter, but that seems to have a rather steep learning curve for relatively inexperienced students... So off the top of your head(s), what would you recommend for this kind of course?
(Boost for reach!)
I’m available for hire. I’ve worked with #rails for the past 15 years, tried a bunch of other frameworks in #python and #elixir. 7 years of experience with #flutter. I especially love working with both rails and flutter.
Preferred timezones UTC-3 to UTC+6
Contributed to and created a bunch of #opensource projects. Links in profile.
Boosts are appreciated.
Why haven't most developers adopted BDD (Behavior-Driven Development) for their tests?
This week in #FDroid (TWIF) is live, but boring. Yes, the cycles run and run, yes 9 new apps are now included, yes 138 more updated. But as things go, with unattended updates, it's all background noise.
What's special? It's the week of UI rewrites:
* #Auxio got #MaterialDesign
* #BadgeMagic is now #Flutter powered
* #Spotube is now #shadcn UI themed

I'm very passionate about emergency #medicine 
and work as a #paramedic (Rettungssanitäter ) on the #ambulance

I love water sports, be it #sailing

Ich bin Florian , #Informatik|student an der #RWTHAachen und #tech-Enthusiast.
Ich hoste vieles im #homelab #selfhosting, programmiere Apps mit #Flutter , aber auch Webseiten und andere #Software .
Zudem begeistert mich die #Notfallmedizin #Medizin und ich bin als #Rettungssanitäter im #Rettungsdienst tätig .
Ich liebe #Wassersport, egal ob #Segeln , #Tauchen oder #Schwimmen .
Think twice before using Flutter (by #Google).
Actually #Flutter does not support translations you make in some languages and I don't know if the Flutter team is aware of the problem or they do it is purpose.
Flutter is … blablabla multiplatform, blablabla, you can build blablabla in the blablabla … but do not accept translations in some « minority languages ».
Blah !
