+## Tasks
+- [ ] Find a way to properly implement the PX4-Commander
+
+## Quick Notes
+### PX4-Commander
+The idea of this module is that there is one instance running that handles all commands that are being sent to the px4 flight controller. Because as soon as the px4-offboard mode is being used we need to stream commands at a minimum of 2 Hz, else PX4 will fallback to another flightmode and thus we loose control.
+If we now want to implement different behaviors that can be combined together, such as a hooklanding, delivery procedure, keep position, loiter, etc. we need a way of sending those commands continuosly without interruption.
+There are different approaches on how we could implement this:
+1. one central node (px4-commander) that runs its main loop and has multiple action servers, where each action server implements one behavior. The central node then manages those actions and makes sure that only one can be executed at the time (I think of it as if we hand a baton from one action server to the next as in a relay race). If no action is actively running the central node immediately runs a fallback (keep position) to keep the drone in px4-offboard mode.
+2. Look at how NAV2 implements this and see if we can copy it. The NAV2 library is implemented well and we should get inspired by it.
+
+
+#### Thoughts
+#osd-thoughts
+Ich kann mich nicht spezialisieren. Nach den heutigen Recherchen sehe ich wie kompliziert ROS2 sein kann (und auch wie effizient). Jedoch kratze ich nur immer an der Oberfläche für eine schnelle Implementierung und kann unsere Software nicht gründlich und langfrisitg implementieren. 
+
+Ich bin gestresst. Heute habe ich fast alle meine Nägel inkl. Haut abgeknabert. Ich war wie in einer Paralyse und konnte mich nicht dazu bringen irgendetwas zu machen. Ich fühlte mich komplett überwältigt und eingefroren. Ich weiss eigentlich was ich machen sollte, kann mich aber nicht dazu bringen es auszuführen.

+ #learning/bite
+If you want to make something visible on any background you can use a harsh contrast change (just like a chess board). On a dark background the white parts will stand out, whereas on a bright background the dark parts will stand out. So you will always be able to see the shape of the object. The same works with neural networks. This was used with our landing hooks

+[[GTest Framework|GoogleTest]] is actually a great method to test your code during development. I should always start with google test instead of a dummy main function that executes stuff and immediately shows if its working or not.
+It is also surprisingly easy to get started with the google test library in C++. You just need to define the following [[CMake|CMakeLists.txt]] in your `test` subfolder:
+```cmake
+# 1. integrate GTest
+include(FetchContent)
+
+FetchContent_Declare(
+googletest
+GIT_REPOSITORY https://github.com/google/googletest.git
+GIT_TAG release-1.11.0
+)
+
+FetchContent_MakeAvailable(googletest)
+add_library(GTest::GTest INTERFACE IMPORTED)
+target_link_libraries(GTest::GTest INTERFACE gtest_main)
+
+# 2. add test executable
+set(test_exe_name ${library_name}_test)
+add_executable(${test_exe_name} test_onesec3d_cpp.cpp)
+
+target_link_libraries(${test_exe_name}
+		PRIVATE
+		${library_name}
+		GTest::gtest
+		GTest::gtest_main
+)
+
+add_test(onesec3d_tests ${test_exe_name})
+set_tests_properties(onesec3d_tests PROPERTIES
+		ENVIRONMENT
+		DATADIR=${CMAKE_CURRENT_SOURCE_DIR}/sample_3d_files/
+)
+```
+Once this is done you can implement your test in the specified executable test file. For example:
+```cpp
+#include <gtest/gtest.h>
+
+TEST(test_onesec3d, test_read_rewrite_equal_hash)
+{
+	// ... do your testing stuff
+	// execute tests
+	ASSERT_EQ(1, 1);
+}
+
+```
+The `DATADIR` environment variable in `set_test_properties` is a smart way to pass the test folder of the build to the test file in order to use assets such as files etc in your tests.
+
+#learning/cpp this seems a good learning resource for cpp: https://matgomes.com/integrate-google-test-into-cmake/

+1. Bevor ich versuche intelligent zu sein und eine automatisierte Test-suite zu schreiben, sollte ich ganz einfache Hypothesen überprüfen. Ich habe heute Koordinaten transformationen gemacht wo ich ein nicht genau definiertes System von Jerry bekommen habe (JSON file mit punkten). Ich habe stunden damit verbracht mein Code anzupassen weil die automatischen Unit Tests nicht funktioniert haben, aber dabei war Jerrys information falsch. Es wäre sehr einfach gewesen das rauszufinden wenn ich mir nur kurz ein paar Punkte genauer angeschaut hätte und +-X, +- Y und +- Z definiert hätte.
+2. [[C++]]: #learning/cpp 
+	1. iterator objects are pointers to a element of a container. In order to get the index of an object we can take the iterator and substract the adress of the first element of the container: `it - container.begin()`
+	2. there are ways to find elements of containers using the standard library: `std::upper_bound`, `std::lower_bound`
+```c++
+auto it = std::upper_bound(radial_distance_map_.begin(), radial_distance_map_.end(), radius);
+
+if (it == radial_distance_map_.end()) { return false; } // couldn't find the radius
+
+mz = it - radial_distance_map_.begin() - 1; // take element just before the iterator to get the 
+```
+3. I have learned a lot about [Spherical Coordinate systems](https://en.wikipedia.org/wiki/Spherical_coordinate_system) today and how the surface of the globe is not equally separated into surface patches. This can be seen when designing a [[Fruxel Grid]] where the longitude is split up into 128 sections and the latitude is split up into 64 sections (which is basically the equi-rectangular projection). The regions close to the poles are very distorted, since the slices become infinitesimally small. The same phenomena manifests itself in [*km per degree* latitude](https://en.wikipedia.org/wiki/Decimal_degrees#Precision) on the globe. Close to the equator every degree corresponds to 111 km, but in Europe (roughly 45°N ) one degree spans only over 78.7 km.

+## Jerry - Project Manager
+> Hey, do you think there is a chance we could get a project manager? I think we could use one! I worked with few great IT project managers, and they really add a lot of value to the team - also they were using great tools and know how to maximize utility of them, like jira etc. I am asking because I think we could avoid many issues in our entire team cooperation, or misunderstandings if there was one good project manager
+
+- no discipline: documenting, making tests (software). 
+	- everyone should be self-disciplined, commits, branching, etc.
+	- IT-product manager
+- Past experience:
+	- Example: 
+		- Floris says Jerry implement 3d map matrix
+		- IT project manager is between Floris and Jerry (jerry can be present and give comments etc.) IT project manager understands the lifecycle (software and hardware). Takes goal and divides it into several tickets based on the scope of the project. Also creates subtasks (e.g document of subclasses,). Assigns Jerry to the subtasks.
+		- Sees gitlab branches (and if its correct) sees commits, assigns someone for review
+	- He is like a glue: he doesn't code. Understands how IT projects work. His work is to stare at jira all day and see if stuff is delayed / missed, etc.
+	- 3 good examples by Jerry
+		- Hamburg Germany BigPoint (gaming web): lead developer: port from flash to unity
+			- 2 project managers (40 people)
+			- standups: only things that were important were discussed (not everyone)
+			- practical example (Jira)
+			- manag: were filter between bosses and employees --> worked with less pressure

+	- lost of trust in institutions (goverment, science as a whole): counter argument from my side: money and capitalism corrupts as well and is wrong incentive. Companies own the world, and the world belongs to the people living on it --> there is a a duty not to destroy it or damage it, which is not followed with pure money incentives.
+		- Dannick lost trust in goverment, because goverment is really bad at directing money to where it has an impact.
+		- maybe there is a way to have the state direct the money to companies (and thus let companies handle the money) by having bounties on open problems that need solving?

+## Quick Notes
+[[Floris]] gave an update on the new hires
+Bayraktar military drones that are used in Ukraine. A lot of applicants have worked there.
+### New Hires
+- senior c++ engineer: autopilot architect. We design a comprehensive software architecture, that is designed to accomplish the final version of the delivery drone. Pathplanning, foundation model, 
+- control systems engineer: math and physics role, not software engineer. Design a control system, test it in the simulator. They can focus in their specialty. Goal is to do a control system (global controller) that can do the entire flight envelope. This is using wind-tunnel testing, and other system identification steps to create an accurate model.
+- embedded linux engineer: vidit can help with embedded software as well. Embedded linux engineer: experienced. Increase the performance of cm4 image pipeline. 
+- Project Manager: create schedule and follow it.
+
+We have a lot of certainty: hardware is settled, foundation model, autopilot architecture --> 6 Months plan where classes and everything is defined.
+Floris is excited about it, because we stop hacking and start developing a market worthy product.
+
+[[Vidit]] asks where we're going.
+- building new drone ([[Dannick]])
+- Create videos of 
+- use videos for business development to launch a pilot project
+- get permits for drone operations: area that isn't close to an airport and is not a big city. Some countries are better (Switzerland, Norway, Estonia, Ireland, Australia).
+- First operation: select area (probably around current swiss office) with large number of villages and towns to create a large service area with the drone. A lot of speed and range with Amprius areas --> connects a lot of restaurants --> creates huge market. 
+	- We had conversations with founder of food delivery company in (eat.ch). Talked to grocery delivery company in eastern europe, looking for partnership to launch delivery service.
+- Markets in Switzerland, Australia, etc. are quite large. Scale-up is possible to 20 million deliveries a year. Then we can certify drone with higher level certificates --> you can extend market to bigger cities.
+- Value proposition is obvious: companies spend $10 per delivery and we can do it for $5, we can do it faster and further away --> open new markets.
+- Pointless to commercialize the product before accomplishing the basic features (hooklanding, etc). 
+- videos are going to be made with the smaller drone.
+
+Most important thing this year: Finish the drone.
+We don't necessarily need the approval of a big company to launch the service.
+
+
+Foundation model is used for:
+- path planning
+- choose delivery surface
+- Drone is sitting in hook, waiting for the package --> detect package to know that human is approaching with a payload box --> open payload bay
+- many more features can be developed with the 3d map from the foundation model
+
+Remote pilot is removed from the loop --> autonomous system directly.
+
+
+Amprius cells:
+- ladezyklen sind sehr reduziert. --> battery pack nur 1x pro Jahr ersetzen
+
+### LED Project
+- mic for my computer (mad-mapper) for sound reactive lights
+- buy SN74AHCT125 level shifters and MAX4466 microphones and switch for martin
+- buy simple leds incl. batteries for all members für maske
+- Make small led project with WLED für meine Maske
+- ethernet boards kaufen für esp32
+- crossover kabel kaufen

+### Physio Update
+Hallo Stephanie
+Danke für die Behandlung von gestern. Heute morgen habe ich die Übungen gemacht und bin nachher mit dem Fahrrad ins Büro gefahren. Beim Bergauffahren hat es plötzlich angefangen mir im Nacken zu schmerzen (vorher hatte ich gar keine Schmerzen). Und wenn ich nun die Schmerztests mache die wir zusammen gemacht haben habe ich folgende Resultate:
+- nach rechts drehen: kein problem
+- nach links drehen: ziemliche Schmerzen, blockiert nach etwa der Hälfte
+- nach oben kippen: leichte schmerzen
+- nach unten kippen: ziemliche Schmerzen auf der linken Seite. Auch blockiert, wegen den Schmerzen
+- nach rechts kippen: okay, leichtes ziehen links
+- nach links kippen: schmerzen links, weniger als wenn nach links drehen.
+
+Ich werde beobachten wie es sich verhaltet.
+Liebe Grüsse
+Claudio
