+  In this blogpost, [@phip1611](https://github.com/phip1611) shows you how you can cope with a
+  relocation by a bootloader in x86 32-bit assembly code.

+  In this blogpost, [@phip1611](https://github.com/phip1611) explains what properties bring the GNU 
+  linker ld to save disk space, as symbols in the `.bss` section do not need to be statically 
+  allocated inside the ELF. Symbols in the `.bss` segment are expected to be initialized to all 
+  zeroes.
+- [GNU ld: Linking .bss into .data to Ensure that Mem Size Equals File Size For Each LOAD Segment (.bss in a PROGBITS Section)](https://phip1611.de/blog/linking-bss-into-data-to-ensure-the-mem-size-equals-file-size-for-each-load-segment-bss-in-a-progbits-section/) \
+  In this blogpost, [@phip1611](https://github.com/phip1611) explains what steps you have to do
+  that the GNU linker put's all symbols of the `.bss` section "as they are" into the binary
+  so that they occupy zeroed memory in the ELF. This is relevant for some very rudimentary 
+  ELF loaders that are found in some microkernels to bootstrap their initial process.

+  In this blogpost, [@phip1611](https://github.com/phip1611) codes with you probably the simplest
+  driver that one can write in assembly. *This blogpost is from September but wasn't mentioned here
