Hey there. Subject says it.
Regular SD cards have a physical switch but MicroSD don't, yet I can't use

I have a card in that state.  I have never found a solution to fix it.


One basic check to do is make sure the file system on the device isn't 
corrupt. If it is that could account for it being mounted read-only.

https://github.com/rust-unofficial/awesome-rust#cryptography is what
scared me off Rust when I was looking at it for a personal project to do
with TLS certificates a year or so ago. Specifically, the multitude of
crates for something that's so easy to get wrong made me wary.

Has the situation changed much in Rust crypto land?

Cheers, Jamon

Now not so much! I don't think there really is a financial paper anymore!

Hmmm - - - - I would love to meet such a group myself!
Critical thinking seems to be quite rare today!! Any suggestions?

Note for relevance: Kobos run Linux.  So do most tablets (iPads and
Windows tablets do not).

Tablets are better than ereaders for many things.  Where ereaders win:

- much much longer battery life

- much smaller and lighter (mine fit in my pockets)

- much less disruptive of sleep (according to many sources, but it may
  not be true)

I don't actually use tablets much any longer.  My phone has all the
functionality of my tablets except the large screen.  When I want the
large sceen out of my house, I take a laptop (which has many other
advantages and is only a little bit more awkward to drag around).

These thing are very personal.  Everyone in my family makes different
trade-offs.

Re: [GTALUG] Increasing interest in the Go language

[David Mason via talk]

I'd also comment on Rust being an interesting competitor to Go.

Rust has better performance, complete statically determined safety
(enforced by the type system), no garbage collection, minimal runtime, and
an active group targeting WebAssembly (i.e. very high performance browser
programs). It's what you should be programming in if you think you need C.

Go has a simpler type system and good-enough performance for many
applications. It might be what you should be programming in if you need a
higher-performance Python (but with a lot fewer libraries).

They both interop with C and C++; I think Rust has a richer set of
libraries (crates they call them).

I considered both for my comparative programming languages course. I went
with Rust in the end because the other languages I talk about all have
garbage collection, and I wanted the students to see how a sophisticated
type system could give you performance as-good-as or better-than C and C++,
along with safety.

I have a Kobo, but stopped using it when I got a tablet.  I have
different readers installed for epub, Kobo, Amazon and library books. 
The tablet also works with PDFs.
