What app was that you used for the ping stats?

@kdfrawg I just looked into it again. Crashplan either changed their policies or I had them confused with another service (probably Backblaze). Though they don't support running headless on a NAS, they do actually document how to set it up so it'll probably work.

For $150/year, I probably should suck it up and give them a whirl.

Thanks! :)

Noble et al. The Left Hand of Equals. Onward! 2016. 13 pages.

What's the simplest possible design for equality in an object-oriented system? The authors range all over from Simula to Smalltalk to Self to Lisp to Java to Scala to object-capability systems like E. Some new to me ideas pop up:

  • Autognostic objects: Objects can only look at their own representation, not another's. Smalltalk objects act like this, but not Simula (or Swift!) objects, which encapsulate at the class rather than the object boundary. Interestingly this allows still to ask if another object is identical to yourself, but not generally if an arbitrary object is reference equals to another from the outside. (Though mirror reflection can intentionally pierce this veil.)
  • Trust implications of object messaging: left.equals(right) only means anything if we trust left to live up to its contract. This matters for stuff like collection.contains(other), where we trust the collection's contents but not the other object. This is demonstrated in detail in the context of the grant matcher problem from the object capabilities literature.
  • Abstract vs Algebraic data types: AbDTs are objects. AlDTs are values whose representation is exposed. These unhelpfully share the same abbreviation as ADTs.

The writing in the first few paragraphs about Simula vs Smalltalk is worth reading just for fun and feel. The quotes from LeGuin's Left Hand of Darkness throughout are also a nice touch.

@kdfrawg I'd need to be very careful to attach external volumes as the right user or users to ensure they get backed up. Miss a month or two, and the backup gets nuked by the service. :\ They intentionally act so as not to be offline archival backups, but just backups of your current laptop/s.

@kdfrawg Yeah, these aren't internal drives is the kicker.

/

@kdfrawg Crashplan doesn't solve the problem for me because most of my files aren't on my consumer device but my NAS. There are hacks to get it to run on there, but not super confident they will keep working. Not exactly inspiring for backups.

Glacier has recurring costs based on the gigabyte-month for storage. Looks to be between 4 and 5 tenths of a cent, [aws.amazon.com] or $4-$5 a terabyte-month. They also charge for retrieval if you need to download.

Here's mine just now. On the far side of the house from the access point, on my 6 Plus (limited to wireless n).

114.7 down, 60.53 up, 5 ms ping

Yeah, weird. May be somewhere on my end, then. I checked a few other sites to see if they were working fine, though, and they were. :\

We had oodles of rain the last few days. Sometimes that does fun things to buried cable. ??‍♀

Good call.
