1. ## Blocking Strangers From Following Me

That looks very suspicious... If somebody truly wants to just read the all messages that you posted, you can't do anything with it because in the worst scenario he or she will write crawler/harvester which will visit person profile every couple minutes or seconds (script with wget/curl in a loop), parse it, and check if sonebody wrote anything new and then parse new messages and add to the database. ps. Beware of attaching photos. Remove meta-data from photos. Don't add photos from smartphone on mobile version of this site directly! Use PC. You have no idea what meta-data they con

Go to your profile. On the left is a list of the people following you. Choose "Options". You can select to not allow others to follow you.

3. ## Blocking Strangers From Following Me

I’ve had a bunch of randos who’ve never even once posted here start “following” me in the last few weeks... I am notified when they begin following. My understanding is that the follow function is basically a subscription to get updates every time I post. My intuition is that it’s not being done for any positive purpose or because they wish to learn from me etc., and may in fact be a coordinated effort to learn more about me and plan for a social engineering attack of some sort. Maybe (hopefully) I’m wrong, but I’d simply rather not have followers. Can followers be blocked?

Like this ? Maybe @Sensei has some ideas ?

5. ## Science plotholes in a book I am writing

Given that you have specified a planet and its moon, rather than a double planet system, there is likely to be a significant difference in the gravity between the two. Presumably your moon is considerably larger than ours, else no atmosphere would have been retained (not to mention plate tectonics and geodynamos either having shut down or never started). Even so one would expect adaptation to a lower gravity. That will place the moonites (for want of a better name) at a distinct physical disadvantage if they are on the planet. Although as @swansonthas pointed out there are unlikely to be

7. ## What are your thoughts on open access publishing?

1) The current model of academic publishing is a #%&ing scam. Nowhere else would the creators of a product not only be expected to sign over their copy rights for free, but also perform the review and editing of others work for free, and have our institutions get financially reamed for access to the #$^ing work we created there in the first place. THEN, with the advent of open access publishing, they get to tack on fees to the tune of$USD 11,320 upfront to the %^(&ing authors. It's really no wonder that the profit margin in academic publishing is ~40%. 2) While the idea of open

8. ## Questions on fat beam lasers...

All lasers eventually diverge; most can be described by gaussian profiles, so they have a minimum spot size (“waist”) at some distance from the laser. Making the beam fat actually improves the divergence issues. The laser used for the moon ranging measurement diverged to be ~2 km across by the time it got to the moon (the atmosphere’s changing density played a part in this); the beam started out several meters wide https://tmurphy.physics.ucsd.edu/apollo/basics.html We use the telescope as a gigantic (3.5 meter wide) laser pointer and also as a signal receiver. Staying clos

Absolutely, yes. It will solve problem with metadata. Lens can have unique imperfections added intentionally or non-intentionally. Analyze of enough amount of raw photos can be used to determine if they came from the same device. Change of resolution i.e. rescale down more than 2x with bi-linear interpolation can help to hide them. The same is with printers, copiers and scanners. Printed page has invisible by naked eye details which can be used for identification of exact printer device and/or model and indirectly person (if he/she is unique user like in home office). If
