I&#39;ll keep trying until I find the right reviewers / venue for this paper.<br/><br/>the draft is available here: <a href="https://joomy.korkutblech.com/papers/kip.pdf">https://joomy.korkutblech.com/papers/kip.pdf</a> 2026-03-17T12:29:34Z https://njump.me/nevent1qqs922dyck6xk06dlplezmf8sj5pdptjc9aw5q4s54qkq2ec2kn9dlgzyqdjv9wgsxqchyw495h6a4uahzkt0ljam8v5w6lrxe6wk5cypkunc4hu99r the UNIX v4 tape reminded me of this story by Ali Akurgal about Turkish bureaucracy:<br/><br/>&gt; Do you know what the unit of software is? A meter! Do you know why? In 1992, we did our first software export at Netaş. We wrote the software, pressed a button, and via the satellite dish on the roof, at the incredible speed of 128 kb/s, we sent it to England. We sent the invoice by postal mail. $2M arrived at the bank. 3-4 months passed, and tax inspectors came. They said, “You sent an invoice for $2M?” “Yes,” we said. “This money has been paid?” they asked. “Yes,” we said. “But there is no goods export; this is fictitious export,” they said! So we took the tax inspectors to R&amp;D and sat them in front of a computer. “Would you press this ‘Enter’ key?” we asked. One of them pressed it, then asked, “What happened?” “You just made a $300k export, and we’ll send its invoice too, and that will be paid as well,” we said. The man felt terrible because he had become an accomplice! Then we explained how software is written, what a satellite connection is, and how much this is worth. They said, “We understand, but there has to be a physical goods export; that’s what the regulations require.” So we said: “Let’s record this software onto tape (there were no CDs back then—nor cassettes; we used ½-inch tapes) and send that.” Happy to have found a solution, they said, “Okay, record it and send it.” The software filled two reels, which were handed to a customs broker, who took them to customs and started the export procedure. The customs officer processed things and at one point asked, “Where are the trucks?” The broker said, “There are no trucks—this is all there is,” and pointed to the tape reels on the desk. The customs officer said, “These two envelopes can’t be worth $2M; I can’t process this.” We went to court, an expert committee examined whether the two reels were worth $2M. Fortunately, they ruled that they were, and we were saved from the charge of fictitious export. The same broker took the same two reels to the same customs officer, with the court ruling, and restarted the procedure. However, during the process, the unit price, quantity, and total price of the exported goods had to be entered—as per the regulations. To avoid dragging things out further, they looked at the envelope, saw that it contained tape, estimated how many meters of tape there are on one reel, and concluded that we had exported 1k to 2k meters of software. So the unit of software became the meter. 2025-12-20T02:20:04Z https://njump.me/nevent1qqsw4k7hceuz0p2fshymnw0xdc8lj8xwyr50d39fdrqahjj2a02sg7czyqdjv9wgsxqchyw495h6a4uahzkt0ljam8v5w6lrxe6wk5cypkunc8dap09 &#34;A Verified Foreign Function Interface between Coq and C&#34;, by me, Kathrin Stark and Andrew W.
