Yes, I agree. Thank you for the advice and leads, much appreciated! I will dig into these. The archive is scoped to letterpress only, so that will automatically skew it more towards latin based typographic cultures, but I would like to find more non Latin stuff, especially Arabic. Haven't yet found very good archives for that though. Some Japanese letterpress works I already have catalogued, and they're amazing: https://garden-of-flowers.heikkilotvonen.com/?filters=japan A recent blogpost by Jacob Filipp has good info on it: https://jacobfilipp.com/hana-no-shiori/ Unfortunately the Japanese archives that I've found have mostly poor quality microfilms though, which makes further search a bit unmotivating.

I hear and accept all your points. I def. recognize the marketing difficulty. Frankly, I was assuming there were folks doing this and I'd get educated on that. Also, really good info on Canada and kudos on compiling that data. I followed your article to this one: https://jacobfilipp.com/the-story-of-canadas-bread-prices-in-1-chart which was a good read. Thanks for your work.

I used to think they were entirely useless, but since then I've learned of many instances where a much better technology is developed because the first iteration is patented. For example, the Wright brothers biggest contribution to aviation was suing everyone using wing warping (https://en.wikipedia.org/wiki/Wright_brothers_patent_war) which greatly advanced the adoption of the much more advanced ailerons. Software patents have a similar effect, for example Cisco's patent on Virtual Router Redundancy Protocol led to the development of the more secure and more capable Common Address Redundancy Protocol (https://jacobfilipp.com/DrDobbs/articles/SA/v14/i05/a6.htm). We tend to invest heavily in whatever we can get working first, but it's rarely close to an ideal way of doing something. By pushing every developer to find a newer, better way of doing something, patents prevent stagnation and lead to more advanced technologies.

I encourage you to get clear on your goals for a project like this. There is a political and social dimension to this work aside from the technical challenge. For example, ordinary people already know whether they're being squeezed or not. They don't need a CPI report. If you want them to believe your CPI report over the government's, then you have to do a lot of marketing. On the opposite side, government decision makers are generally moving away from a "technocrat" data-driven approach to decisions, towards a "great man" theory of decision making: giving them better CPI data won't suddenly make them care about using data again. A lot of people are putin in work to dismantle American government capacity, and there are worse problem than inflation tracking. My personal opinion is that it doesn't make sense to create a community-driven CPI as a direct alternative to the government CPI. But it does make sense to collect a lot of this data for other uses (ex: to highlight illegal collusion among merchants, archival). From a technical perspective, here are some thoughts from a Canadian lens: * CPI calculations are already fairly transparent. You can read about the work that goes into them (click TOC on upper right: https://www150.statcan.gc.ca/n1/pub/62-553-x/62-553-x2023001-eng.htm) * Government-collected raw data is not open to the public, because merchants wouldn't have give the govt' access to their POS data if it were otherwise. The Canadian government made a tradeoff:…

Visual Studio surely, as they had a collaboration with Microsoft using Windows CE for the Dreamcast. https://jacobfilipp.com/MSJ/directx.html "What happened to Windows CE on the SEGA Dreamcast?" https://www.youtube.com/watch?v=QKHSlBi5qok "Making Dreams Come True - Sega's Katana!" https://www.youtube.com/watch?v=EIr9YnMgExA Maybe it was for the Saturn and previous consoles?

Like who? I recently noticed an Al Williams who is a writer on hackaday [1]. Turns out he was a regular contributor to DDJ. Not to be confused with Al Stevens who wrote the C Programming column for years. The search on the page seems to be broken at the moment, but the one on https://jacobfilipp.com/thedoctor-search/ still functions. [1] https://hackaday.com/author/wd5gnr1/

I was genuinely expecting this to be LLM-generated. Also, what’s his problem with the “Witch Priestess from the North?” EDIT: Oh, the blue backgrounds are links. https://jacobfilipp.com/new-lord/

Before Windows Internals book we all know (called Inside Windows NT in its first editions), there was Windows Internals and other books and articles by Matt Pietrek. It starts from disassembly of WIN.COM studying the insides of DOS to figure out under which more or less common version of MS-DOS Windows is being run. Other well known anecdotes and pieces: https://jacobfilipp.com/msj-index/ https://web.archive.org/web/20240318233231/https://bytepointer.com/res…

A quite memorable article [1] described a “backwards” message-passing technique in C++ using operator overloading so you could do stuff like: obj<-method arg1 arg2; [1] https://jacobfilipp.com/DrDobbs/articles/DDJ/1996/9608/9608e/9608e.htm

I think Windows and DOS do have good documents. I actually think they had way better ones than Linux at the time. But I could be wrong. For reference: https://jacobfilipp.com/msj-index/ And also MSDN.

The oldest defer-like feature I can find reference to is the ON_BLOCK_EXIT macro from this article in the December 2000 issue of the C/C++ Users Journal: https://jacobfilipp.com/DrDobbs/articles/CUJ/2000/cexp1812/alexandr/al… A similar macro later (2006) made its way into Boost as BOOST_SCOPE_EXIT: https://www.boost.org/doc/libs/latest/libs/scope_exit/doc/html/index.h… I can't say for sure whether Go's creators took inspiration from these, but it wouldn't be surprising if they did.

I have a soft spot for red-black trees ever since reading about them in Dr. Dobbs - it's the first time I remember reading about a data structure (and it went mostly over my head at the time - but the fond memory remain): I believe it was the 1992 article by Bruce Schneier: https://jacobfilipp.com/DrDobbs/articles/DDJ/1992/9204/9204c/9204c.htm
