Git Alias – ignore all whitespace

dave — Fri, 23 Mar 2012 17:31:02 +0000

A talk at last year’s Chicago Code Camp spoke about Git aliases. Up until now I used shell aliases in the (wonderful) MINGW32 Git Bash shell, so “$ gs” is $ git status.

$ git diff is something I use a lot, but sometimes you want to ignore whitespace, say when you reformat an XML config file.

$ git config alias.di 'diff --ignore-all-space'

now, $ git di does what I want.

Canon MF5470dw

Just got a new Canon MF5470dw print/fax/scan laser. Printed, but no scan. Helps if you don’t set it at the same IP address as the HP DeskJet. Stupid noob mistake. Works great with Vuescan!

SSH public key and Bitbucket

dave — Sat, 26 Nov 2011 16:16:56 +0000

So I use Bitbucket to host several private Hg repos, all working great from Windows via Putty and Pageant.

Today I tried to update the local repo.

C:\bin\app>hg pull
sending hello command
sending between command
abort: no suitable response from remote hg!

WTF? Tried different machines, other accounts, same problem.

Bit of Googling… some users report Bitbucket messes up the public keys, at arbitrary times, as they all share the hg user.
Updated the public key on Bitbucket with the SAME value. It even looked different, like it was missing a character. Now it works…

C:\bin\app>hg pull
pulling from ssh://moc.tfoscad.ghnull@gh/dacsoft/bin
searching for changes
no changes found

Go figure.

Best Eulogy Ever

Rest in Peace, Dennis

Centos Fun with a locked Boot. Thanks, Hudson 2.1.1.

dave — Fri, 02 Sep 2011 21:55:29 +0000

Say the Hudson script locks up during boot, for example, after you upgrade to 2.1.1 and it does not work and someone said removing the –daemon argument makes it work and something else fails so you roll back the hudson.war and restart and it now locks up on boot. No SSH – sshd is the next service to load. I had to “power down” the VM, and tried to “force the runlevel“: several ways, say, using “init=/bin/sh 3″. Nothing worked.

The obvious thing is to do the Interactive Boot (type I). Someone said this didn’t work, so I didn’t try. Liars. Worked great. Said “Y” until I hit Hudson, typed “N”, and then “C”ontinue… voila!

2.1.1 has some problems. Wait until 2.1.2 at least.

Upgrading Atahualpa

Did you know that if you upgrade the Atahualpa theme from the Update page in the WordPress Admin, it deletes all the custom header images in your website?

Me neither.

Upgrading WordPress in Bulk

dave — Sun, 17 Apr 2011 15:05:54 +0000

Of course there is the old faithful Updating_WordPress_with_Subversion and Upgrading_WordPress_Extended, but there is a lot of fluff there. Old blogs are “You are using WordPress 2.9.1″. Show me the command lines.

Certainly.

“Backup your database. Read Backing Up Your Database for a detailed explanation.”
- Use Plugin WP-DB-Backup from http://austinmatzko.com/wordpress-plugins/wp-db-backup/
- Download it – make sure the copy is here. Open it up.
“Backup ALL your WordPress files in your WordPress directory. Don’t forget your .htaccess file.”
- Make a local shadow directory
  - $ rsync -vur ./sarajane/ ./backups/sarajane-snapshot-20110416/
- Make a tar file for download for archive
- $ tar cvf sarajane-snapshot-20110416.tar sarajane/
- $ gzip sarajane-snapshot-20110416.tar
- Verify the backups you created are there and usable. This is essential.
“Deactivate ALL your Plugins.”
“Ensure first four steps are completed. Do not attempt the upgrade unless you have completed the first four steps.”
Gotta upgrade the MYSQL Database? I did… The nice thing is, use two different ones. Since you saved the original directory, you can switch back to old state and db by replacing the directory.
- Per Backing_Up_the_Database
  - $ mysqldump --add-drop-table -h mysqlservername -u mysqlusername -p dbname> ms-db-backup-20110416.sql
- Per Restoring_Your_Database_From_Backup
  - $ mysql -h mysqlservername -u mysqlusername-p dbname< ms-db-backup-20110416.sql
edit wp-config.php (save the old one)
$ cp wp-config.php wp-config.php.save
$ vi wp-config.php ...
Use new SVN install into new folder

$ mkdir sarajane2
$ cd sarajane2
$ svn co http://core.svn.wordpress.org/tags/3.1.1 .

Copy these files from your old site to the new
- $ export OLDBLOG=$HOME/sarajane
- $ export NEWBLOG=$HOME/sarajane2
- $ cp $OLDBLOG/wp-config.php $NEWBLOG/
- $ ls $OLDBLOG/wp-content/cache
- $ rm -rf $OLDBLOG/wp-content/cache
- $ ls $OLDBLOG/wp-content/plugins/widgets
- $ rm -rf $OLDBLOG/wp-content/plugins/widgets
- $ rsync -vur --exclude=.svn/ $OLDBLOG/wp-content/ $NEWBLOG/wp-content
# this only is in older WP installs
- $ rsync -vur --exclude=.svn/ $OLDBLOG/wp-images/ $NEWBLOG/wp-images
- $ cp sarajane/.htaccess sarajane2
Swap directories
- $ mv sarajane sarajane0
- $ mv sarajane2 sarajane
Hit the upgrade link
- http://localhost/wp-admin/upgrade.php

Atualhalpa stores settings in the database, so you don’t have to copy anything.

Final ledger entries

dave — Sat, 16 Apr 2011 13:49:24 +0000

For three days now I have been trying to figure out how to account for payments to the Clinic via PayPal. The money goes into my personal PayPal account, and credits against money owed me for expenses, but I just don’t want to post the delta, I want to track what happened so the cash flow report is accurate. I tried a lot of accounts, but always ended up with the debits and credit balances fighting so the cash flow was backwards. Then I read this post who recommended that I treat the PayPal account like a bank account. I created “PayPal Bank”, receipts were deposits, and actual transfers into the account were transfers. Works like a charm.

So how do I account for donations of cash? Duh. Contribution Revenue.

It’s so nice when things work out. Now I can actually finish the books and work on my OWN taxes.

Epsilon woes

Walgreens.
Chase.
1800Flowers.com.

Dear 1800Flowers.com Customer:

One of our email service providers, Epsilon, has informed us that we

It’s important to know that this incident did not

Jeez, doesn’t anyone do their own email anymore?

Seems to be a lot of new spam. Popfile is getting most of it, but some new stuff in the Inbox. Morons.

osql -> isql -> aargh on Ubuntu

dave — Thu, 17 Mar 2011 22:02:48 +0000

Trying to set up ODBC on Ubuntu. osql is a great script to test it out, but running it on Ubuntu 10.10:

root:~# osql -S fcstest -U sa -P ***** osql: error: no potential directory strings in "/usr/local/bin/isql" isql strings are: + /lib/ld-linux.so.2

So inspecting the code, I can extract the meaningful parts on RHEL, where it works:

ISQL=$(command -v isql) strings ${ISQL} | grep ^/ /lib64/ld-linux-x86-64.so.2 /usr/local/lib

but on Ubuntu, the same sequence:

dchwalis:/usr/local/src$ strings ${ISQL} | grep ^/ /lib/ld-linux.so.2

Note the missing /usr/local/lib – the grep filters following will NEVER find any strings…

Maybe we should do this: RHEL:

$ ldd /usr/local/bin/isql libodbc.so.1 => /usr/local/lib/libodbc.so.1 (0x00002b5b76eb4000) ...

and Ubuntu:

root:/usr/local/bin# ldd isql libodbc.so.1 => /usr/local/lib/libodbc.so.1 (0x001cd000)

We can pull a path from that!
