Nice post. Didn't even know about the bundle flag until now.

Re: Meaningful primary keys beat sequences and UUIDs

Jim McKeeth — Mon, 19 Mar 2018 00:57:59 -0000

Nice idea, but there are a few problems.

1) What happens when the same golfer plays two rounds of golf at the same club in the same day? Might not be that common of an occurrence, but if it could happen we either need to support it or prevent it.

2) What if we have two golfers with the same initials? We have to query the table until we find a variation that works. To make matters worse initialst distributed evenly over the alphabet, so the most common names will take the most time to enter since they have to hunt for an available variation.

3) What happens when a golfer changes thier name? Maybe it was entered wrong the first time, or they changed their name. Whatever the case people and clubs change their names. Do we update all the keys? What if we have archived some data, do we need to update the keys in all the data warehouses too? This brings us back to point 2 again if we have an initial collision.

At some point, the amount of data required to uniquely and clearly identify a row, and not result in collisions, will exceed that required for a UUID and will approach the number of bits in the other columns.

We had a system we were designing that had multiple disconnected databases that would eventually sync up. There was no way to have a centralized sequece generator. We finally came up with a system involving timestamps, unique identifiers, and local sequences that was satisfactory for uniquely identifying rows. It was 2 bytes short of a UUID, so we went with a UUID.

Oh, and that is not the usage of an HMAC.

I really like the cultural context of movies and literature that you bring to your reviews.

Yes, validino looks nice. Thanks.

Form me FormEncode is pain. I like easy approach. Something like Web2py at data level defined easy validators: Field(xxx, requires=IS_EMPTY_OR(IS_DATE(..))).
Does some separate library for validation other then FormEncode exist? And is FormEncode the mainstream?

Re: How to use vimdiff as the subversion diff tool

Matt Wilson — Thu, 22 Jan 2015 17:07:53 -0000

I ran into that problem plenty too! I created these two aliases in my ~/.bashrc file:

alias boringdiff='svn diff --diff-cmd=/usr/bin/diff'
alias prettydiff='svn diff --diff-cmd=$HOME/bin/diffwrap.sh'

Then I commented out the line in the .subversion/config file.

I hope that helps!

Is there a way to make this automatically switch to the old spew-the-diff-to-the-terminal mode when piping or redirecting the output to a file? That'd be really nice for patch creation (rather than having to do `svn diff --diff-cmd=...` every time for that).

Tried this. It spat out a load of text, the last line of which was: Daemonize..
and then it just hung. I Ctrl-C'ed out and I of course was still not connected.

Thanks you man. It helped. All I want to add that inside ~/.subversion/config file character `~` is not expanded to $HOME. It is recommended to pass the full path of the script or to keep the script in $PATH.

What is the profit of logging.critical(''.join.traceback.format.... in hook? why not just use logging.exception(ex) oneliner there?

Thanks Phil. Live trap is set. Watching some kickass youtube tutorials on how to make snares. And this guy offers private tutoring: snareone.com
Maybe in a few months I'll get people to endorse me on LinkedIn for making First Blood style traps.

Sorry dude. That sucks. The next step is to trap that critter, bite its head off and leave it outside as a message to the others.
