X11: How does “the” clipboard work?

https://www.uninformativ.de/blog/postings/2017-04-02/0/POSTING-en.html

Even worse than I thought. 1. Clients retain the data, so must keep a window around to 'own' the selection, but not the primary one because that may close. 2. You can specify a data type to get the data in, but there's no guarantee it'll be specifiable as MIME so good luck figuring out how to request the type you want. 3. Even though the client retains the data you can't request more than about 256k at once and everything larger must be retrieved in chunks via the X server. 3. There are two common clipboards and it is basically a matter of trying one and then the other. 4. There are also more clipboards (by convention) and in fact unlimited clipboards (the identifier is just an X atom). 5. Working around this with a clipboard manager is humourously inefficient because to re-host the clip data the manager needs to retrieve it with all its target types, and there is no way to discover which ones don't require the client to do extra work (e.g. GIMP providing 50 mime types for image data)

What Really Happened with Vista – Hacker Noon

https://hackernoon.com/what-really-happened-with-vista-4ca7ffb5a1a

1. MS neglected important hardware trends (mobile) because they were focused on software innovation; key features of successful devices in the 2000s (battery life, connectivity) were not really about software. 2. The focus on managed code as a response to security vulnerabilities was terribly overambitious and resulted in MS dropping the ambitious parts halfway through the development cycle.

Is the Hard Problem of Consciousness Connected to the Hard Problem in Physics?

http://nautil.us/issue/47/consciousness/is-matter-conscious

From my notes to M: not that convincing: Basically the argument is, as I understand it: 1. Science doesn’t tell us about “things in themselves”, but only about how they relate to other things. In other words we can accurately describe how a photon behaves, but we can’t say what exactly a photon fundamentally *is*. 2. It doesn’t make sense to have a universe of relationships between things but no actual things. 3. Consciousness is a way of describing things-in-themselves (the concept of “something being red” for example, which is something you understand as a thing even if you can’t really describe it) 4. So we posit that this set of things-in-themselves is the actual structure of the universe (the hardware) and everything we do is just describing interactions between those things (the software).

This claims to talk about consciousness, but actually ends up making the argument that to efficiently and dynamically make predictions one needs a) a rich variety of input categorisations and b) a locus of attention, neither of which require consciousness.

Zipf’s Law Arises Naturally When There Are Underlying, Unobserved Variables

http://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1005110

Really interesting proposal that Zipf's distribution arises so frequently because latent variables with narrow energy distributions, when combined, give a distribution with wide energy distribution, which is necessary and sufficient for a Zipfian distribution. Example: Zipf on word distributions can be explained by the distribution of parts of speech (where the word frequency within parts of speech is not Zipfian, i.e. has narrow energy distribution).

The limitations of Android N Encryption – A Few Thoughts on Cryptographic Engineering

https://blog.cryptographyengineering.com/2016/11/24/android-n-encryption/

Interesting article on something I didn't know anything about: full-disk encryption isn't suitable for phones because they're on all the time (meaning the keys are always in memory). Instead you want file-based encryption and per-file control, so that you can throw away the keys to most stuff when the device is locked, but still retain access to files which must be accessible at all times. Android 7 has made a small move in this direction, but it sucks, whereas Apple has been doing it better for the last five years.

BashPitfalls - Greg's Wiki

http://mywiki.wooledge.org/BashPitfalls

Bash (and all shells except possibly fish) is fucking terrible. The whole in-band signalling concept that shells are built on is a nightmare. When abominations like 'cd -P -- "$(dirname -- "$f")"' are the correct way to do basic stuff like "cd to the file's directory" we should just give the whole thing up and go back to meaningful column positions. I defy anyone who has not read "bash pitfalls" to come up with that cd line by themselves (including Stephen Bourne). And the whole page is full of those. Some of them are for exotic things (filenames starting with -, or containing newlines) but in 2016 it's routine to find new shell scripts and Makefiles which don't even deal with spaces, and the reason is that nobody banging out a quick shell script has the time to read through "bash pitfalls" to ensure they're doing it right. More like "bash pits of despair". Burn it all.
