Scalable Vector Extension (SVE) is a vector extension the A64 instruction set of the Armv8-A architecture. Armv9-A builds on SVE with the SVE2 extension. Unlike other SIMD architectures, SVE and SVE2 do not define the size of the vector registers, but constrains it to a range of possible values, from a minimum of 128 bits up to a maximum of 2048 in 128-bit wide units. Therefore, any CPU vendor can implement the extension by choosing the vector register size that better suits the workloads the CPU is targeting. The design of SVE and SVE2 guarantees that the same program can run on different implementations of the instruction set architecture without the need to recompile the code.

Signals GObject signals can be used to notify applications of events specific to this object. Note, however, that the application needs to be aware of signals and their meaning, so if you're looking for a generic way for application-element interaction, signals are probably not what you're looking for. In many cases, however, signals can be very useful. See the GObject documentation for all internals about signals.
app.asar 이라는 파일이 있어서 찾아보니 electron의 컴파일(?)된 파일이라고 한다.
압축되어 있다는데 data 파일로만 나와서 zip 등으로 풀순 없고
npx asar extract 명령을 통해서 특정 디렉토리에 풀면된다.
$ npx asar extract app.asar asarResources Need to install the following packages: asar Ok to proceed? (y) npm WARN deprecated asar@3.2.0: Please use @electron/asar moving forward. There is no API change, just a package name change npm WARN deprecated @types/minimatch@6.0.0: This is a stub types definition. minimatch provides its own type definitions, so you do not need this installed. npm WARN deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported npm WARN deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.

It is Electron issue, when Electron-libs don't match your system --in-process-gpuoption helps as workaround. Also--disable-gpu-sandboxor--no-sandboxoptions helps too
