- The Epistle to Philemon is a Pauline epistle of the New Testament of the Christian Bible. It is a prison letter, authored by Paul the Apostle (the opening verse also mentions Timothy), to Philemon, a leader in the Colossian church. Paul does not identify himself as an apostle with authority, but as “a prisoner of Jesus Christ”, calling Timothy “our brother”, and addressing Philemon as “fellow labourer” and “brother” (Philemon 1:1; 1:7; 1:20). Onesimus, a slave who had escaped from his master Philemon, was returning with this epistle wherein Paul asked Philemon to receive him as a “brother beloved” (Philemon 1:9–17). The letter appeals on behalf of Onesimus, who subsequently became a Christian through Paul. Paul requests that Philemon receive Onesimus not as a slave but as a beloved brother in Christ, offering to repay any debt Onesimus owes.
- Inside the Apple-1’s shift-register memory (righto.com)
Apple’s first product was the Apple-1 computer, introduced exactly 46 years ago, on April 11, 1976. This early microcomputer used an unusual type of storage for its display: shift register memory. Instead of storing data in RAM (random-access memory), it was stored in a 1024-position shift register. You put a bit into the shift register and 1024 clock cycles later, the bit pops out the other end. In the early days of random-access memory chips, shift-register memory was cheaper so many systems used it. The downside, of course, is that you had to use bits as they became available, rather than access arbitrary memory locations.
