PSA: If you use OneDrive on Mac, and your company has changed how it identifies the OneDrive folder, you might get more than one OneDrive folder which you cannot remove, not even using sudo.

The way to reset things — assuming nothing is pending from uploading to OneDrive — is to follow the instructions in this Microsoft support page.

You're welcome!

Reset OneDrive - Microsoft Support

Resetting Microsoft OneDrive can sometimes resolve sync issues. Follow the steps to reset your OneDrive.

Combined Public Service Announcement and Today I Learned: if you have `CLICOLOR=1` on macOS, if you do an `ls` of a directory which is inside iCloud Drive, evicted files (i.e., those that cannot be immediately used, but need to be downloaded first from iCloud) show with a grey background… see below:
First, both files are in iCloud, but not locally available. They have a dotted cloud icons in the iCloud Status field of the Finder window, and a greyed background in the output of the `ls` command.
Second, the `cssday.pdf` file shows a filled circle with a down arrow as part of their iCloud Status, which represents the "Keep Downloaded" option (i.e., the file has been downloaded and is locally available), while the other file keeps the dotted cloud icon. In that case only the `Screenshot…` file is shown as grayed out in the output of `ls`.

Public Service Announcement: If you've worked in the UK, and you've changed the UK number that you use for accessing Gov.UK services, it is impossible to restore access because the default recovery workflow requires UK-issued photo ids: either a UK passport, or a UK driving license, are mandatory, even if you never had one or provided one in the first place.

Happily enough, as long as you keep your National Insurance Number, you can create a new Gateway ID, but this time following the steps provided by @the3million in this link, using the GOV.UK ID Check app… that way, if you have a biometric passport, and access to a modern enough iPhone or Android phone with contactless payment built in, you can verify your identity with non-UK passports.

You're welcome! (Including myself in the future…)

@kottke That’s a nice way of putting it. Of course, it is around 10^76 times a normal lifespan… which itself is still almost 10^69 times the current estimated age of the universe… so not really in a hurry to start worrying 😉

An alternate way of looking at this (but more complicated) is to look at this relative velocity change over time. This second diagram shows all the time differences, day-by-day, for both Voyager 2 and Voyager 1. Red means the distance is increasing, blue is decreasing. Each year is plotted vertically, with January at the top and December at the bottom. The years increase to the right, so launch (1977) is farthest left in both panels. We can see from Voyager 1 that there is a slow settling to a regular pattern. Voyager 2 is more complicated, but we can see that each planetary encounter altered the pattern considerably. The brighter yellow areas show when the Voyagers are barely moving with respect to Earth, and we can see that this happens earlier in the year for Voyager 1 than for Voyager 2. Look for Voyager 2's day-to-day change to decrease slowly too over the next few weeks! Voyager 1 won't start making up lost 'ground' until sometime in April.
Those of you tracking the distances here or on 'that other social channel' will have noticed that the _change_ in the reported distance to Voyager 1 has been slowly _decreasing_. How can this be? Is Voyager returning? ...no. This happens near this time of year, every year. You have to remember that these distances are being measured from a moving platform: Earth.
Earth's orbital speed is faster than that of either spacecraft, so at certain times of year, Earth will catch up, and the distance decreases for a little while. This means that if you plot out the distance over time, the lines for both Voyager 1 and Voyager 2 wiggle, as in this first diagram.

ALMA Discovers “Space Tornadoes” Around the Milky Way’s Core!

Although the galaxy’s central molecular zone (CMZ) has long been known to be filled with swirling dust and gas molecules cycling through formation and destruction, the mechanism that drives this process has remained elusive. Molecules serve as tracers for various processes in molecular clouds, with silicon monoxide (SiO) particularly useful in detecting the presence of shock waves.

Using ALMA’s high resolution and sensitivity to map distinct spectral lines within the molecular clouds at the center of the Milky Way, the team led by Kai Yang (Shanghai Jiao Tong University) has delineated a new type of long, narrow filamentary structure at a significantly finer scale. The dynamic interaction between this turbulent environment and the slim filaments produced as shocks ripple through provides a more complete view of the cyclical processes within the CMZ.

Yang’s team reports it remains unknown how these slim filaments initially arise, but shock processes emerge as a likely explanation.

ALMA Discovers “Space Tornadoes” Around the Milky Way’s Core  | ALMA Observatory

Swirling through the Milky Way’s central zone, surrounding the supermassive black hole Sgr A*, dust and gases constantly churn as energetic shock waves ripple. An international scientific team using the Atacama Large Millimeter/submillimeter Array (ALMA) has sharpened our view of this action by a factor of 100, discovering a surprising new filamentary structure in this...
