Re:John Snow Cholera Data on Friday October 23, 2026 @08:47PM (#50217313)
Could a Crime Map Review Have Stopped Repeat Arsonist from Setting Woman Afire? (Feb 2026) https://slashdot.org/submission/17344558/could-a-crime-map-r...

In 1854, Dr. John Snow famously put cholera death data on a map to help readers see that reported deaths in Soho, London were in the vicinity of the Broad Street pump, which was the source of the contagion, as well as to shift from an understanding of cholera as airborne to waterborne. Snow's map certainly reinforces the value of putting data on a map to help readers see the patterns revealed, which is as important to contemporary thematic mapping as it always has been — geography and cartography were showcased during the Covid outbreak.

Such mapping techniques aren't just useful for infectious disease epidemiology, but it should be noted that the maps still need to be reviewed and analyzed, not just created. A sad reminder of this is the recent court appearance of Lawrence Reed, the man charged with setting a woman on fire on a Chicago Transit Authority subway train on Nov. 17. With more than half of her body burned, the victim — who reportedly remains in critical condition — got off the train and collapsed at the Clark/Lake CTA stop, just a few hundred feet away from Chicago's City Hall, which Reed was also later charged with trying to burn down just three days earlier on Nov. 14. In a press conference, Chicago Mayor Brandon Johnson suggested the Nov. 14th City Hall arson may have been political in nature ("this type of violence has no place in our politics"). Days later, he called the Nov.17th CTA fire attack horrific but isolated, but later recharacterized it as an 'absolute failure' of justice, mental health systems after reports broke of Reed's extensive criminal record ("This individual was charged with dozens of felonies over the past three decades," Johnson said. "He was clearly seriously mentally disturbed and was a danger to himself and to others. The system that we had failed to intervene.").

Incredibly, Reed's past felonies also included trying to burn down the State of Illinois' Thompson Center (now being rehabbed by its new owner, Google) — which is across the street from the site of the City Hall arson attack and houses the station where the CTA fire attack victim collapsed — on April 23, 2020 as Governor JB Pritzker was preparing to hold his daily COVID-19 press conference inside the building.

So, while it may be a little unfair to "armchair quarterback" the investigation into Reed's November 2025 arson crimes with the benefit of hindsight, one can't help but wonder: Would a simple review of a Chicago Crime map for historical arson crimes in the immediate vicinity of City Hall (map) right after the Nov. 14th arson have called out Reed's 2020 arson (map) at the State of Illinois Thompson Center and led to his apprehension before he got the chance to set afire the woman who collapsed at the subway station in the Thompson Center (map) three days later, especially since Reed's whereabouts were readily available from the electronic ankle monitor he was wearing while awaiting trial for another violent attack?

By the way, don't count on Copilot to automatically connect the map dots for crimes. An attempt to do so was initially stymied by Copilot's refusal to even acknowledge Reed had any connection to the horrific CTA arson attack.

In a similar vein, the "Costs of Switching Schoolchildren Between Windows, Chrome, Mac?" (https://slashdot.org/submission/17349696/costs-of-switching-...) begins:

If you've ever made the jump from PC to Mac (or vice versa) at work or home, you're painfully aware that there are very real costs of switching platforms in terms of lost knowledge and productivity. In addition to flushing years of accumulated knowledge down the toilet — goodbye Outlook-Teams-OneDrive-SharePoint-Excel-Word-PowerPoint-VBA, hello GMail-Workspace-GDrive-Sheets-Docs-Slides — there's also the matter of a thousand UI and other "paper cuts" to contend with ("Why are you looking for a 'prt sc' key," condescendingly replies a Mac aficionado in response to a question from a former Windows user, "when Shift+Command+3 is so intuitive?").

Re:Account bans on Reddit on Wednesday October 07, 2026 @12:49AM (#49988329)
In my experience, https://discuss.python.org/ was also pretty trigger-happy with the account bans (for posting a link to an already-presented PyData presentation and code that was totally uncommercial). Eventually found a more obscure category with a much smaller number of participants to post it in where it got an OK reception. It seemed they were just completely overwhelmed with off-topic submissions in the high-volume categories, and this was before AI slop even came into its own.
Nice to see the tech giants finally launch hard spending caps in 2026, matching some but not all of the resource/spend limiting features ($, compute, disk, tape, print, time) that were baked into mainframes and time sharing systems in the early 1970s! Everything old is "modern" again!

Re:Pre-2022 Books on Saturday June 20, 2026 @09:14PM (#48614730)
Tech documentation has been kind of a three-decade race to the bottom, with some ups and downs along the way. From vendor documentation in the 70's to Windows Help in the 90s to the rise of tech books incl. O'Reilly to fill the gap, to PDF and Internet document, and now to often lacking-in-detail Javadocs, Python docs, API interface, API docs, event/parameter lists, and GitHub README files that are passed off as documentation today, often with no detail, use examples, illustrations, or though-through overall structure and organization.

In addition to the obvious negative effect on learning curves, I'd argue this dearth of "long-form documentation" has a negative impact on programming language and app development, as well as software usability in general (isn't CONTROL+COMMAND+SHIFT+3 for a MAC screen capture intuitive?)..

AI has become the new "teacher of record" to fill this documentation void, but it's very individualized and narrowly focused. There's no longer a shared mental model, where everyone has read the same books and are working somewhat off the same page. Ironically, it's probably never been easier to write a good tech book, but there's likely zero money in it and the search and AI giants are likely to hover it up and start serving snippets of it up for free before you see a dime, making people very unlikely to buy your book, even if you've written a technical masterpiece!

Re:How to convert between wealth and income tax on Friday May 22, 2026 @06:58PM (#48242653)
And even if the house represents negative wealth - same property taxes apply to a house regardless of whether the owner owns it outright with no mortgage (wealthy) or if they're paying 8% interest on an underwater mortgage (negative wealth). And, unlike VCs, property taxes are paid - often for decades - before one even sees if they'll even realize any wealth from the estimated value of their home that they pay tax on.
Re:Killed by Apple on Monday May 11, 2026 @11:10AM (#48096054)
Maybe add the TV series "Scraper"?

At Gawker, They Battled a Billionaire. 10 Years Later, the Scars Are Still Healing https://www.hollywoodreporter.com/business/digital/inside-ga...

Jefferson and Read had sold a scripted series to Apple titled Scraper that was based on the inner workings of Gawker, and the quartet, along with a handful of, as Carmichael puts it, “very accomplished, amazing screenwriters and playwrights on Broadway,” were producing scripts for the first season. [...] “Max and I had been concerned about that when we sold the project to Apple,” says Jefferson, but the executives developing the project “told us there was a very protective firewall between the TV side and the tech side.” But a month before the writers room wrapped with scripts for the first season’s eight episodes, Jefferson recalls, “an executive called me and said word had reached Tim Cook that we were doing a show set in a world similar to Gawker, and he had put the kibosh on it personally.” Jefferson and his 3 Arts Entertainment manager Jermaine Johnson (who also represents Read and Carmichael) say they heard about but never saw an email in which Cook allegedly referred to Gawker as rife with “vile human beings.” (Cook did not respond to requests for comment.)

Re:Logging Sucks on Sunday December 21, 2025 @03:37PM (#46348172)
Just out of curiosity, how have you seen risk/compliance, regulatory, and audit departments at organizations deal with the disconnect between security and privacy for something like mainframe logging (e.g., JES2, JES3), which is typically inherently governed, and modern distributed logging, which is typically inherently permissive? Both are vastly different approaches, but each is somehow considered 'compliant.' Btw, employees at a company I was at were once investigated for insider trading simply because it was discovered the company used pooled logs that were accessible by production support programmers (the company decided to override the default mainframe security), which was deemed a possible source of insider trading information that could be tapped into by those who had log access (programmers were eventually cleared if it was discovered their small personal trades were immaterial and just coincidental with the company's trading, but the investigation led to uncomfortable confrontations for some!).
