comment How do you compile dependencies manually? Cygwin
Do you have /usr/include/openssl (as seen from inside cygwin, e.g., with ls) Should have a bunch of .h files there. If so, you have the openssl-devel package installed... and I'm not sure what else to try.

comment How do you compile dependencies manually? Cygwin
@thisisjnd Unfortunately, you need 20 rep on the site to chat. I tried to create a room to explicitly let you in, but it appears only a diamond-mod can do that. Anyway, I honestly haven't used cygwin in almost a decade. Other than trying to help you find the OpenSSL development package in the cygwin installer, I'm not sure what else to try. If you want to find it in the installer, search for ssl. And make sure to tell it to install development headers.

OpenSSL's libcapi is not its own cygwin package, that's why its not showing in "Select Packages". Try searching for "ssl" instead.

comment Best way to undo a release-upgrade?
If you're using LVM or btrfs, you could take snapshots. But really, upgrades are one-way... You need a test environment (could be as simple as a VM somewhere) so you can test upgrading.

comment How does the system know when a file has been modified? In particular memory mapped files
@Mouse.The.Lucky.Dog Well, depends on what you mean by modify a file. Either truncate or link/rename would seem to qualify. (Remember also that truncate doesn't just set the file size to 0—it lets you pick any length. Even growing the file.)

comment Change Router PPPoE Via SSH
@Gilles agree, but that doesn't seem to be the case here. Or at least if it does, doesn't look like OP is using it.

comment Change Router PPPoE Via SSH
Probably a good idea. The question seems to be about configuring Pace's router software, not about the Linux kernel its running on top of.

I'm unclear, what does this have to do with Unix and/or Linux?

comment CRON Permission Denied
I suggest trying strace -f -p `pidof cron` and see if you can't find out where that permission denied is coming from. (That will make a lot of output, you'll want to become familiar with strace before trying it...)

+1 Indeed, there are tools already written and debugged, and they should be preferred over quick hacks.

comment TAR Backup to Remote Server
I'm unclear what you're trying for. It sounds like you want to set up rsync on your laptop, then after rsync finishes, run tar on the server? In which case, isn't that just rsync … && ssh user@server 'tar …' ? But have you considered backup software?

comment Where does ext4 store directory sizes?
I'd add that this isn't just ext4; stat simply doesn't have a way to return multiple sizes—so it can only return the size of the directory itself, not of its contents. And also "directory size including contents" becomes less clear when you have hardlinked files.

comment Are system calls the only way to interact with the Linux kernel from user land?
@BruceEdiger this causes a signal to be raised, which seems more interacting than the scheduling interrupt, which is mostly transparent to the process. It does as much as the kill syscall would...
