[ISFP] Adventurer. Introverted Emotional Type with a Sense of Extroversion (MBTI)

The ISFP is a cognitive function of the Fi-Se, so it makes decisions based on its own feelings and values from information obtained through the five senses. Although they tend to conform to their surroundings because they don't want to get into conflict with others because it is troublesome, they have the image of being free-spirited artists and having a seemingly contradictory state of being at their own pace.

[Thinking Fitness] How do you train yourself to keep thinking instead of thinking?

Of course, being to the point, having a quick mind and being able to concentrate at a moment's notice are important, but only up to the upper middle level. From there onwards, the people will be at the same level as the above base, so I personally think that the two factors of 'health' and 'thinking stamina' make the difference.

[ESP32] How to deal with stack overflow error after MQTT communication that occurred after migration to ESP-IDF

Stack overflow is a phenomenon in which a task runs out of allocated stack memory Stack overflows can occur due to the receiving or parsing process of MQTT messages Sometimes it can be solved by changing the stack size setting in the sdkconfig file. This can be resolved by changing the stack size setting in the sdkconfig file.

[MBTI] How would you apply each type in a startup role, if you were the CEO, to your organization?

Although it is a trivial consideration and a delusion, I will list, at my own discretion and prejudice, the type of business and organisational structure that would be likely to be built if each MBTI type were applied in a start-up role and if each type were to become CEO. Business and organisational management: ENTJ / ESTJ / ENFJ.

[PdM] How to prioritize products? Identifying the trunk and branches

Product managers (PdMs) tend to be busy with a mountain of requests for functional improvements from other departments and customers, especially in the growth phase, depending on the phase of the product. This article describes my theory on how to prioritise products as a PdM.

[JLCPCB] I received a confirmation email after ordering 100 boards. PCB operation is not checked

If there is no problem with the PCB layout, you will not receive an email from JLCPCB, so if you receive an email, it is when there is a problem, such as an incomplete circuit. Also, JLCPCB does not check the functionality of your own PCB, so you need to look at the schematic and PCB yourself to determine if the order is correct.

[Docker] Understanding inter-container communication. external configuration and access methods

For inter-container communication in Docker, you first need to manually create an existing Docker network. Afterwards, set external: true in docker-compose.yml.For inter-container communication, the port mapping of the host is irrelevant and the internal port is used directly.

[Docker] Port mapping. port numbers appear a lot, so I organized them.

When Dockerising and accessing services inside the container, the Docker container itself is an environment that is also independent of the host machine, so access is only possible via the container port.There are two ways to configure Docker port mapping: using the docker run command or using docker-compose.yml.

[ESP32 x PlatformIO] How to coexist the framework with Arduino and ESP-IDF

PlatformIO allows the Arduino and ESP-IDF frameworks to be used together: by setting framework = arduino, espidf in platform.ini, many existing Arduino libraries can be used directly, thus reducing the need for code porting This saves time and effort in porting and rewriting code.

[App] Create a grid post for iOS screenshots with Figma

iPhone screenshots do not require images at all iPhone display sizes; if the app's UI is the same across multiple device sizes and localisations, simply provide screenshots at the highest resolution required.
