Jackson County, Missouri, has declared a state of emergency and closed key offices indefinitely as it responds to what officials believe is a ransomware attack that has made some of its IT systems inoperable.

"Jackson County has identified significant disruptions within its IT systems, potentially attributable to a ransomware attack," officials wrote Tuesday. "Early indications suggest operational inconsistencies across its digital infrastructure and certain systems have been rendered inoperative while others continue to function as normal."

The systems confirmed inoperable include tax and online property payments, issuance of marriage licenses, and inmate searches. In response, the Assessment, Collection and Recorder of Deeds offices at all county locations are closed until further notice.

The US Supreme Court on Tuesday heard arguments in a case seeking to limit access to the abortion and miscarriage drug mifepristone, with a majority of justices expressing skepticism that the anti-abortion groups that brought the case have the legal standing to do so.

The case threatens to dramatically alter access to a drug that has been safely used for decades and, according to the Guttmacher Institute, was used in 63 percent of abortions documented in the health care system in 2023. But, it also has sweeping implications for the Food and Drug Administration's authority over drugs, marking the first time that courts have second-guessed the agency's expert scientific analysis and moved to restrict access to an FDA-approved drug.

As such, the case has rattled health experts, reproductive health care advocates, the FDA, and the pharmaceutical industry alike. But, based on the line of questioning in today's oral arguments, they have reason to breathe a sigh of relief.

After more than a year as an exclusive invite-only social media platform, Bluesky is now open to the public, so anyone can join without needing a once-coveted invite code.

In a blog, Bluesky said that requiring invite codes helped Bluesky "manage growth" while building features that allow users to control what content they see on the social platform.

When Bluesky debuted, many viewed it as a potential Twitter killer, but limited access to Bluesky may have weakened momentum. As of January 2024, Bluesky has more than 3 million users. That's significantly less than X (formerly Twitter), which estimates suggest currently boasts more than 400 million global users.

Google-owned security firm Mandiant spent several hours trying to regain control of its account on X (formerly known as Twitter) on Wednesday after an unknown scammer hijacked it and used it to spread a link that attempted to steal cryptocurrency from people who clicked on it.

“We are aware of the incident impacting the Mandiant X account and are working to resolve the issue,” company officials wrote in a statement. “We've since regained control over the account and are currently working on restoring it.” The statement didn’t answer questions asking if the company had determined how the account was compromised.

The hacked Mandiant account was initially used to masquerade as one belonging to Phantom, a company that offers a wallet for storing cryptocurrency. Posts on X encouraged people to visit a malicious website to see if their wallet was one of 250,000 that were eligible for an award of tokens. Over several hours, X employees played tug-of-war with the unknown scammer, with scam posts being removed only to reappear, according to people who followed the events.

Revisiting a classic game from the AUTOEXEC.BAT/CONFIG.SYS era of MS-DOS can be a fun distraction. But the more friction and configuration between you and a playable game, the more likely you are to fall off before you ever hit the menu screen. You spend enough time fine-tuning your modern systems; doing so within an arcane framework, for a single game, is not everybody's idea of fun.

DOS_deck seems to get this, providing the most frictionless path to playing classic DOS shareware and abandonware, like Doom, Jazz Jackrabbit, Command & Conquer, and Syndicate, with reconfigured controller support and a simplified interface benevolently looted from the Steam Deck. You can play it in a browser, right now, the one you're using to read this post.

In fact, I stopped between that last sentence and this one to play a couple levels of Doom in a Chrome browser. And now I've taken another punctuation break to play the first level of Syndicate, which moves much faster than I remember. The control schemes are clever, the interface is easy to get used to and move around, and there's a host of little extras to appreciate, including constant game progress (game state) saving, and linking and setting certain games as favorites.

If you've ever drizzled honey on a piece of toast, you've noticed how the amber liquid folds and coils in on itself as it hits the toast. The same thing can happen with 3D and 4D printing if the print nozzle is too far from the printing substrate. Harvard scientists have taken a page from the innovative methods of abstract expressionist artist Jackson Pollock—aka the "splatter master"—to exploit the underlying physics rather than try to control it to significantly speed up the process, according to a new paper published in the journal Soft Matter. With the help of machine learning, the authors were able to decorate a cookie with chocolate syrup to demonstrate the viability of their new approach.

As reported previously, Pollock early on employed a "flying filament" or "flying catenary" technique before he perfected his dripping methods. The paint forms various viscous filaments that are thrown against a vertical canvas. The dripping technique involved laying a canvas flat on the floor and then pouring paint on top of it. Sometimes, he poured it directly from a can; sometimes he used a stick, knife, or brush; and sometimes he used a syringe. The artist usually "rhythmically" moved around the canvas as he worked. His style has long fascinated physicists, as evidenced by the controversy surrounding the question of whether or not Pollock's paintings show evidence of fractal patterns.

Back in 2011, Harvard mathematician Lakshminarayanan Mahadevan collaborated with art historian Claude Cernuschi on an article for Physics Today examining Pollock's use of a "coiling instability" in his paintings. The study mathematically describes how a viscous fluid folds onto itself like a coiling rope—just like pouring cold maple syrup on pancakes.
