[@gla](https://mastodon.social/@gla) A couple of months ago, someone told me they allow the LLM to create its own file and use a diff tool to jump quickly from typo to typo. I think if I switch to a new system, that’s what I’ll go with.

But I would like to see your system if you have it posted somewhere.

the UNIX v4 tape reminded me of this story by Ali Akurgal about Turkish bureaucracy:

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&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.

Unsure Calculator

filiph.github.io/unsure

The Uncertainty Calculator enables users to perform calculations using precise numbers and ranges (e.g., 4 or 4 ± 6) to express uncertainty. It simplifies statistical reasoning for everyday decisions, helping users gauge potential financial outcomes in uncertain situations.

Key Features

  • Input both exact numbers and ranges with a tilde (~) to denote uncertainty.

  • Operates on basic mathematical operations: addition, subtraction, multiplication, and division, and supports functions like exponentiation, square roots, and trigonometric functions.

  • Utilizes a Monte Carlo method for computations, providing a probabilistic range of results.

  • Design is basic and intentionally user-friendly, aiming to empower those without deep statistical knowledge.

Limitations

  • Calculation speed is slower due to Monte Carlo simulations, and the formula parser may show errors.

  • Only normal distributions are assumed for ranges, providing a simplified model for uncertainty.

Practical Applications

  • Estimate financial viability of business ideas, calculate potential investment returns, assess risks, and more, all accounting for uncertainty in key variables.

There's a piece of monologue in a Czech theatrical comedy that I'm quite fond of, and it goes something like this: “According to our carbon dating analysis, this letter was written on January 21, 1842, plus-minus two thousand years.”

Spotlight on pdfly, the Swiss Army knife for PDF files

chezsoi.org/lucas/blog/spotlight-on-pdfly.html

pdfly is a CLI tool to manipulate PDF files, written in Python and based on the fpdf2 & pypdf libraries. It can:

- display PDF metadata using pdfly meta and pdfly pagemeta commands
- combine files into new PDF documents: it can extract specific pages & merge documents (pdfly cat); selectively remove pages (pdfly rm); convert images to PDF documents (pdfly x2pdf); and even compress documents (pdfly compress) or build booklets (pdfly 2-up & pdfly booklet).
- pull out specific content from PDF files: pdfly extract-images & pdfly extract-annotated-text.
- fix manually-edited PDF documents, so that they can be opened in a PDF viewer again!

I don't like the phrase "Technical Debt". It's effectively lost all meaning.

I always need to ask, "what about it is technical debt?"

I've gotten a variety of responses:
- the abstractions are wrong
- the performance is bad
- the technology is out of date
- it's undocumented
- I don't know the tech

That last one in particular when someone told me, "It's technical debt because I don't know the tech," is when I knew the phrase had lost all meaning.
