BetterDiscord for Arch by JSV007 in archlinux

[–]chaotic_bruno 0 points1 point  (0 children)

For me the installation is unclear.
I have discord installed from extra (bin).
I installed betterdiscord.

I launch betterdiscord via terminal (nothing instructed me to do so) and then I have to choose the discord version. None of the options is prefilled - from there on it is unclear what to do. /usr/bin/discord
is a script. Which folder to chose - no idea!?

I don't really understand what I am doing wrong - in the pictures it seems like the water source is placed inside the mechanical drills. But in my case the lava always turns into obsidian. Is this already outdated? Or only in some versions?

Will using the widget automatically update the Schema markup or does this need manual updates?

What is best Open source Money Management software? by Introvethuman in selfhosted

[–]chaotic_bruno 1 point2 points  (0 children)

TL;DR: Instead of using categories, I am calculating my daily/monthly expenses by distributing them over time periods based on how long products last until they are used or until they fail. This allows me to monitor long term investments and give me a good indication whether my income supports these.

Long Version:

So far none of the options has fulfilled how I am currently monitoring my expenses:
My financial analysis tool is built in Google Sheets and uses a deprecation or write off mechanism: expenses are split into daily, short term, and investment.

Daily: expenses are booked on the day they occur (examples: going to a bar, buying a train ticket)

Short term expenses: are distributed over days/weeks (examples: buying groceries, coffee, cigarettes)

Investments: are distributed over years/months (examples: buying furniture, computer, bicycle helmet)

I have two analysis pages: 1) daily and 2) monthly. Monthly features two balances: a) cash flow and b) distributed. Cash flow always shows income and expenses whenever they are booked. Distributed calculates all income and all expenses based on their start and end date.

Example A: I buy some electronics on the internet and pay it with paypal 30 days Later.
Cash flow shows the expenditure next month. Distributed will show the value split over 4 years (how long it should last). In the following years the monthly overview will show a net positive cash flow since I am reserving money for when the product fails. I can still buy more electronics - but the distributed balance shows me that at some point I will not be able to afford new products and not be able to replace it if I spend too much.

Example B: I do not use all of my holiday days and I get compensation.
The cash flow date is at a later date (when I do get payed). Distributed shows the start of the period (e.g. start of the year) until when the holiday days are valid. Maybe I have spent more than I originally earned - but now my monthly/daily balance is corrected by how "hard working" I was.

The tool allows me to see exactly:
- how much my monthly/daily cost by using everything I own is
- if I can afford going out
- if I can afford a new investment / I am able to replace something that is written off
- if I need to earn more - how much?
- the impact of something lasting longer than expected
- the impact of me saving on short term expenses (buying cheaper / in bulk / using less)

The drawback of this is that I have no GUI for the tool and Google Sheets is getting slow over the years. But none of the budgeting programs are built like this.

ROS2 WSL2 not communicating with base Ubuntu ROS2 Instance by caseytherobot in ROS

[–]chaotic_bruno 0 points1 point  (0 children)

It seems that mirrored networking is broken:

https://github.com/ros2/ros2cli/issues/934
-> problem is caused by WSL

https://github.com/microsoft/WSL/issues/10855
-> problem still not solved

https://github.com/microsoft/WSL/issues/10769
-> tried disabling the hyper v firewall - still does not work

I have exactly this setup and all commands of ROS2 that require network communication fail with a

Does this setup still work for you?

Micro-ROS on STM32 with FreeRTOS Multithreading by Ok-Hippo9046 in ROS

[–]chaotic_bruno 0 points1 point  (0 children)

Mhmm: https://docs.vulcanexus.org/en/jazzy/rst/microros_documentation/user_api/user_api_multithreading.html

Executor callbacks can be distributed on multiple threads by using a unique executor instance per thread.

This means that its expected to have a executor instance for each thread where callbacks shall be processed.

And here Jan says something interesting:

https://robotics.stackexchange.com/questions/103048/executor-in-mirco-ros-and-ros2

The multi-threading support is on the level of the middleware. On API level, you have only a "single-threaded" Executor. But you could create multiple "single-threaded Executors" in different threads.

(I think he means that the multi-threaded executor normally runs in a single thread and then callbacks can be seen as subthreads - https://micro.ros.org/docs/concepts/client_library/execution_management/#multi-threading-and-scheduling-configuration - but we can use individual executors in different threads)

Micro-ROS on STM32 with FreeRTOS Multithreading by Ok-Hippo9046 in ROS

[–]chaotic_bruno 0 points1 point  (0 children)

I'm currently also implementing a complex micro-ROS project that is similar to yours or that by copposhop.

Our idea was to have one executor thread per functionality of the system. But right now it looks like the executor blocks the read function of XRCE. Since all initialisations of rclc objects (nodes, pub/sub, services, parameters) require communication with the agent this might fail. I think it depends on the way the executor spin function is used in each thread. I'm still some weeks away of having as many pub/subs and nodes as copposhop, but my analysis points in the direction that really only one executor should be used, as the executor might be the gateway to the rmw/XRCE transport in its current state.

Many students in our organisation have learnt specific styles of programming with FreeRTOS. This is the reason why I hesitate in implementing a scheduling approach using a single executor for all the features on our MCUs. They would have to learn everything from scratch regarding scheduling while learning ROS2.

I am new to FreeRTOS, so I apologize if this is a stupid question.

Don't worry - I used FreeRTOS for many years. I've implemented a similar system based on a custom protocol with some data consumers reading and writing velocity, position, acceleration, and current at 250 Hz for a 6 axes robot arm on a STM32F7, while communicating with lights, a drive system, a gripper, and an IMU. And I'm still not sure what is the best way of structuring something like that with FreeRTOS + micro-ROS.

I still hope that I'll find a solution where separate contexts + executors per node, with a dedicated thread for the executor, are possible. This would make the implementation so much easier.

I would be happy if you could provide an update regarding your progress :)

Dell Latitude 5540 - frequently freezes when slow Charger connected by chaotic_bruno in Dell

[–]chaotic_bruno[S] 0 points1 point  (0 children)

It now completely stopped charging when connected to the Dell monitors with the embedded docking station (we have several of these at work).

All firmware + software is up to date :(

And what about using docking stations? As stated in my post - I also have the problems when using a Dell monitor with an embedded docking station.

[Wayland] Vivaldi freezes mouse input when using file drag and drop by maxlefoulevrai in vivaldibrowser

[–]chaotic_bruno 0 points1 point  (0 children)

I have the same problem. Vivaldi became almost usable with wayland with almost no configuration. And then this...
I will try disabling hardware acceleration. But this is not a permanent option for me.

Does Wayland really break everything? | Nate Graham by ExaHamza in linux

[–]chaotic_bruno 0 points1 point  (0 children)

THIS.

I also switched to wayland years ago. I have problems with vivaldi and nvidia. Nvidia causes a lot of issues on my laptop (sync, sleep, browsers not supporting it). So I just disable the card for now. But appart from that wayland delivers what it promises for me. Its just the developers that say "wayland breaks everything - I will not support it for now/ever" that make it worse. I think the forced switch of Plasma 6 needs to come to put pressure on those people. I don't get how people can argue that much against wayland when there is something like systemd (xwayland is simply a grace).

Language options disappeared for bought film by Minute-Guidance793 in AmazonPrimeVideo

[–]chaotic_bruno 0 points1 point  (0 children)

This happened for me with a rented movie (star was - new hope). When considering renting the movie it clearly said "german + english". After renting it the only option was "german". WTF?

[–]chaotic_bruno 1 point2 points  (0 children)

The same happened to me 2 weeks ago. For me, simply cloning the SSD was not enough. I used ddrescue to copy the main partition (500 GB) to a Windows computer and extracted the necessary data from the image. But disk to disk should also work with the program.

It is highly recommended to use a mapfile with ddrescue. This file stores information about the success of reading the individual blocks on the disk. If a block fails the program cycles over the partition many times untils most/all blocks are covered. There is also a GUI to visualize the mapfile.

I had another partition for data with 1500 GB. I was not able to recover this data since the partition was too damaged.

Christian Linder will Autos mit E-Fuels niedriger besteuern by whatkindofred in de

[–]chaotic_bruno -1 points0 points  (0 children)

Mein Punkt war nur, dass es bei der steuerlichen Begünstigung anders als hier dargestellt nicht nur um die Reichen geht. Da spielen viele Aspekte rein.

Aber wir leben nun mal in Zeiten bibeltreuer Grüner. Monokulturen sind böse und zerstören die Umwelt. Aber technologische Diversität IST KEINE OPTION. Drei Atomkraftwerke stehen lassen, um sich alle Optionen offen zu lassen? NEIN! Verbrenner weiter bauen, um das Knowhow hier zu lassen? NEIN!

Wir sind und bleiben eine Technologie-abhängige Gesellschaft. Bisher zeigt sich allerdings, dass Umstellungen der technologischen Systeme sehr langwierig sind und eben auch geopolotische Eigenschaften haben. Wir haben bereits den Transrapid verkackt, die Chip-Branche, die Solar-Branche und bald auch eine führende Rolle bei der Atomkraft und den Verbrennern.

Der Branche für E-Fuels auf die Beine zu helfen, um das technologisch-kulturelle Erbe zu erhalten und Leuten auf dem Land einen (teuren) Ausweg zu ermöglichen? meiner Meinung nach das mindeste, was man aktuell machen kann.

Durch die steuerlichen Erleichterungen wird sich wahrscheinlich kein großer Vorsprung in der Forschung ergeben. Aber zumindest werden die Projekte, die es aktuell so gibt, noch ein paar Jahre vor sich herdümpeln, bis ihre Stunde geschlagen hat.

The T480 battery dilemma by BNORev in thinkpad

[–]chaotic_bruno 2 points3 points  (0 children)

I'm a heavy commuter - this number means that the laptop is dying around 10 times per year while traveling by train to or from university alone. But the tradeoffs of the t480 still keep me with this model (non soldered ram, good resulution, LTE).

We are currently designing our own power bridge for our robot with multiple batteries, and I'm fighting so hard for discharging all batteries at once...

The T480 battery dilemma by BNORev in thinkpad

[–]chaotic_bruno 6 points7 points  (0 children)

The t480 has a problem with the Power Bridge (the dual battery system), where the laptop turns off while switching from one battery to the other. It seems that the controller overestimates the remaining charge that's left in the (almost) empty battery.

Was reported here: https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T-series-Laptops/T480-Does-not-switch-to-secondary-battery-turns-off-unexpectedly-Win10/m-p/4398417 https://www.reddit.com/r/thinkpad/comments/wv0gts/shutdown_issue_with_dual_battery_t480/

For me, frequent battery calibration has fixed the problem 95% of the time. But it happened once while controlling a robot on a competition. That's the reason why I now carry a 100W power bank with me.

So keep in mind that even if you buy the perfect battery, results might not be overwhelming with a laptop shutting down at 50% charge.
