I found an interesting barrel plug cable. Thought I'd share in case anyone else is looking for a 5.5mm barrel power plug. No clue if it's any good.

Looks like it's available in 5v 5A to 28v 5A and the cable will only supply the rated voltage or 5v if the power supply can't supply the required voltage.

It does have a datasheet, which unfortunately is written in a language I can't read. Doesn't look like it comes with a power supply.

I see two issues with it. First, I don't have a boat load of spare USB-C PD power supplies so this solution winds up costing me more. Second, while the voltage is printed on the cable, it's printed grey on black so it probably going to be hard to read and once that wears off your back to playing "what's this cable".

This cable includes an EMARK chip

This cable is 1.2 meters long

Tip is 5.5mm outer diameter, 2.5mm inner diameter with center positive voltage, but it's springy so it works just fine for 2.1mm as well.

A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer Indiana University, and had his homes raided by the FBI. No one knows why.

Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.

He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data. I have personally spoken to him on three occasions for articles here, here, and here.

"None of this is in any way normal"

In recent weeks, Wang's email account, phone number, and profile page at the Luddy School were quietly erased by his employer. Over the same time, Indiana University also removed a profile for his wife, Nianli Ma, who was listed as a Lead Systems Analyst and Programmer at the university's Library Technologies division.

According to the Herald-Times in Bloomington, a small fleet of unmarked cars driven by government agents descended on the Bloomington home of Wang and Ma on Friday. They spent most of the day going in and out of the house and occasionally transferred boxes from their vehicles. TV station WTHR, meanwhile, reported that a second home owned by Wang and Ma and located in Carmel, Indiana, was also searched. The station said that both a resident and an attorney for the resident were on scene during at least part of the search.

Attempts to locate Wang and Ma have so far been unsuccessful. An Indiana University spokesman didn't answer emailed questions asking if the couple was still employed by the university and why their profile pages, email addresses and phone numbers had been removed. The spokesman provided the contact information for a spokeswoman at the FBI's field office in Indianapolis. In an email, the spokeswoman wrote: "The FBI conducted court authorized law enforcement activity at homes in Bloomington and Carmel Friday. We have no further comment at this time."

Searches of federal court dockets turned up no documents related to Wang, Ma, or any searches of their residences. The FBI spokeswoman didn't answer questions seeking which US district court issued the warrant and when, and whether either Wang or Ma is being detained by authorities. Justice Department representatives didn't return an email seeking the same information. An email sent to a personal email address belonging to Wang went unanswered at the time this post went live. Their resident status (e.g. US citizens or green card holders) is currently unknown.

Fellow researchers took to social media over the weekend to register their concern over the series of events.

"None of this is in any way normal," Matthew Green, a professor specializing in cryptography at Johns Hopkins University, wrote on Mastodon. He continued: "Has anyone been in contact? I hear he’s been missing for two weeks and his students can’t reach him. How does this not get noticed for two weeks???"

In the same thread, Matt Blaze, a McDevitt Professor of Computer Science and Law at Georgetown University said: "It's hard to imagine what reason there could be for the university to scrub its website as if he never worked there. And while there's a process for removing tenured faculty, it takes more than an afternoon to do it."

Local news outlets reported the agents spent several hours moving boxes in an out of the residences. WTHR provided the following details about the raid on the Carmel home:

Neighbors say the agents announced "FBI, come out!" over a megaphone.

A woman came out of the house holding a phone. A video from a neighbor shows an agent taking that phone from her. She was then questioned in the driveway before agents began searching the home, collecting evidence and taking photos.

A car was pulled out of the garage slightly to allow investigators to access the attic.

The woman left the house before 13News arrived. She returned just after noon accompanied by a lawyer. The group of ten or so investigators left a few minutes later.

The FBI would not say what they were looking for or who is under investigation. A bureau spokesperson issued a statement: “I can confirm we conducted court-authorized activity at the address in Carmel today. We have no further comment at this time.”

Investigators were at the house for about four hours before leaving with several boxes of evidence. 13News rang the doorbell when the agents were gone. A lawyer representing the family who answered the door told us they're not sure yet what the investigation is about.

This post will be updated if new details become available. Anyone with first-hand knowledge of events involving Wang, Ma, or the investigation into either is encouraged to contact me, preferably over Signal at DanArs.82. The email address is: dan.goodin@arstechnica.com.

One bit (out of context) from the article that made me chuckle:

Rubio told Sikorski: “No one has made any threats about cutting Ukraine off from Starlink. And say thank you because without Starlink, Ukraine would have lost this war long ago and Russians would be on the border with Poland right now.”

In fact, Russians are already on the border with Poland because the Russian region of Kaliningrad lies on Poland’s northern border.

Supply and Demand.

If there is no supply of good public infrastructure, inclusive institutions, good governance, etc. people will go elsewhere.

And also, lol.
