How was last night everyone?

[Esther Yarnold]

Sorry I didn't make it in end... didn't get the earlier train I wanted
which meant I wasn't back in Bournemouth 'til after 11pm - I was
putting IKEA furniture together all day! Think it may be time to get a
proper job!!

Hi Esther,

It was a bit quiet, I arrived at 8pm, nursed a drink for twenty minutes
before wandering off round the block for a look at the church. Just set
off on the drive home when I saw Mr Stow arrive by bicycle; the
Weymouth train didn't stop at Parkstone so he visited Bournemouth. It
soon got a lot more rowdy when Mr Wolff arrived; they turned the music
up to lip-reading level. So us three from Dorchester/Weymouth, the same
as the last Poole meet. :-)

Cheers, Ralph.

Oh :( not so great then... what is it with pubs and loud music!! Save
that for the night clubs I say... I think the problem with the meets
over this way is that there's already meetdraw and B&W, so maybe a bit-
oversaturated?? But I like the Dorset Digital ones as they're nice and
cosy!!

Yes, the Wey-Waterloo train goes twice an hour but only every other
one stops at the little stations... Mr Stow needs to geek it up and
get himself a train app ;)

I was working 'til 8 in North London and was hoping to get the 8.35
train back so I'd be in time for last orders but alas I didn't get to
Waterloo in time.

Hopefully, I won't be in London for the next one!

Hi,

Some topics that were sign-languaged the other night in the pub. I
think I've forgotten quite a few in the interim. :-(

Flask, a web microframework written in Python.
http://flask.pocoo.org/docs/foreword/#what-does-micro-mean

It defaults to the Jinja2 templating engine. http://jinja.pocoo.org/

The graph, as in nodes and arcs, database Neo4j has a new release.
http://neo4j.org/
http://blog.neo4j.org/2012/04/neo4j-17-ga-bastutrask-bank-released.html

Postgres has an HStore module allowing a column to be a key-value store,
treading on NoSQL's toes a bit.
http://www.postgresql.org/docs/9.1/interactive/hstore.html
https://postgres.heroku.com/blog/past/2012/3/14/introducing_keyvalue_data_storage_in_heroku_postgres/

Two-part history of how ARM came about, from Acorn's beginnings,
including the first test chips running without power. Lots of 70s'
hair.

Cheers, Ralph.

and - as for Neo4j - i think i mentioned a new Pragmatic Programmers
book - 7 databases in 7 weeks:
http://pragprog.com/book/rwdata/seven-databases-in-seven-weeks

[ in the same vein as their 7 languages in 7 weeks...]

And Ralph mentioned some hidden away Google page which does some sort
of social graph marlarkey - hopefully he can provide a link?

Hi Stephen,

> And Ralph mentioned some hidden away Google page which does some sort

I did, didn't I. http://www.google.com/s2/search/social For me, it
shows up the other locations of order 1 connections, e.g. last.fm, where
I have no account. And then there's the oodles of order 2 connections.

Cheers, Ralph.

Hi,

Another thing I forgot: making MySQL work better at its mysql(1)
command line.

Instead of having

select * from foo;

spew one possibly very long row on each line and have the line be too
wide for the terminal, end the statement with \G instead of semicolon.

select * from foo\G

This gives one column per line with a heading between rows.

If `pager' is set then all results are fed through it rather than
printed directly to the screen. It can be set for the current session
at the mysql prompt,

mysql> pager less -F
PAGER set to 'less -F'
mysql>

or alter ~/.my.cnf to have

[mysql]
pager = less -F

for a permanent setting.

less(1) is the normal Linux text pager, like MORE in DOS; its name is a
pun on architect Ludwig Mies van der Rohe's "Less is more" aphorism.
Its -F option is AKA --quit-if-one-screen; if there's less than a
screeful you won't have to enter `q' to quit less. It's much more
complete than DOS's MORE, letting you page back and forth, highlight
search results, etc.

There's many other possible options to less, it takes default ones from
the LESS environment variable. I have mine set to

$ echo $LESS
-wiXz-2$j15
$

to make it comfy. See `man less' for what they do. You'll be viewing
the man page in less. :-)

Sometimes the \G format can still result in a very long line wrapping on
the screen. While viewing the mess in less enter `-S' to toggle that
option on the fly and long lines are chopped at the end of the terminal
rather than wrapped.

\G and less(1) make mysql(1) much more usable; handy if you're ssh'd in
to a remote server on a text interface.

Cheers, Ralph.

Y'know - I really love these sort of frameworks. I'm much more likely to reach for something like Flask (or Perl's Dancer, or Ruby's Sinatra) than something like django, catalyst or rails.

They seem much more in the unix tradition to me. Small pieces loosely joined - rather than a massive framework that takes three months to learn :-)

Cheers,

Adrian

I was introduced into the the buzz-phrase "NewSQL" at GOTO Copenhagen last week to cover the way that some "traditional" databases are dealing with the NoSQL buzz/hype. Apparently the term has been around for a while but it had passed me by.

Folk also might want to take a look at http://datomic.com/ - came across it in the clojure track and it looked rather fascinating. Closed source though.
