Isaiah 17:4 speaks of a time of judgment for Israel, symbolizing the loss of its former strength and prosperity. The “glory of Jacob” will be diminished, and the nation’s abundance (“fatness of his flesh”) will fade, leading to a period of hardship and weakness. This serves as a warning of the consequences of Israel’s disobedience, reflecting the broader theme of God’s judgment on nations that stray from His covenant. The verse emphasizes the transient nature of worldly prosperity and the importance of remaining faithful to God.

How the 8086 processor determines the length of an instruction (righto.com) The Intel 8086 processor (1978) has a complicated instruction set with instructions ranging from one to six bytes long. This raises the question of how the processor knows the length of an instruction.1 The answer is that the 8086 uses an interesting combination of lookup ROMs and microcode to determine how many bytes to use for an instruction. In brief, the ROMs perform enough decoding to figure out if it needs one byte or two. After that, the microcode simply consumes instruction bytes as it needs them. Thus, nothing in the chip explicitly “knows” the length of an instruction. This blog post describes this process in more detail.
