At the MySQL commandline, you can enter
and see what processes are running.
If you’re tracking down some problematic code and you’ve got a query (or set of queries) that don’t end, consume CPU cycles and generally bog everything down to a crawl, it can be helpful to know what time you’ve run the command above. Thusly, I now run this:
show processlist; select now as current_date_time;
and it rather nicely tells me the current date/time on the MySQL server, using the Time column from the processlist, you can work out a tad more accurately when a query started, giving you a starting point to look in other logs.
Now those long running sql queries are easier to track down.
I use Day One to journal. There is a service that creates a new Day One entry from the selection, but it didn’t have a hotkey associated with it. So I’ve set one up.
First (optional) step is to use to make your CAPS LOCK key useful. Big thanks to Brett Terpstra for that, I use that for loads of other shortcuts.
Next step is to add a shortcut for the New Day One Entry With Selection using the instructions to create keyboard shortcuts in the Apple knowledge base.
I used CAPSLOCK D as the hotkey to send whatever I’ve got currently selected to Day One as a new entry, works a treat.
Note: this is ^⇧⌥⌘–D using the optional first step, so it is the same as pressing Control, Shift, Option, Command, D all at the same time.
I just needed to compress and encrypt some files on Mac OS X. The following command does that:
zip -ejr TARGET SOURCEFOLDER
This will ask for a password (twice to confirm it), encrypt and compress the sourcefolder and put it into a file named target (and auto add the .zip extension).
To unzip it do this:
unzip SOURCE -d TARGETFOLDER
This will ask for the password, decrypt and uncompress it into the targetfolder.

This article here describes how to get Hazel to run rules in sub folders, very handy. I’m using this to move any screenshots taken on the iPhone out of the photo folder into a separate folder.

Here’s how to enable a checkbox to be updated enmasse.

Then put that file into at the following location
Of course, you’d want to check any existing files in the folder to make sure none of them already deal with that field.
From the linux command line, these commands let you backup and restore a SugarCRM database.
Update 2016-04-26: Just saw this SugarCRM KB Providing a Backup Without Sensitive Data which is really useful. Thanks Jared.
Firstly, for a proper back up of SugarCRM you’ll need two ﬁles, one containing the application ﬁles, one containing the SQL database.
First up, the backup…
Change to the folder you want to backup, then…
tar -zcvf CRM-BACKUP-FILES.tar.gz .
Edit: if you get an error ‘Permission Denied’ you may be trying to write to a folder you don’t have permission for, instead try writing to ~/CRM-BACKUP-FILES.tar.gz and it will likely work.
Edit: see also this StackOverflow article.
Backup sql (empty copy of the database):
mysqldump -u USERNAME -p -–no-data DATABASENAME > CRM-BACKUP-SQL.sql
Backup sql (with the data) :
mysqldump -u USERNAME -p DATABASENAME > CRM-BACKUP-SQL.sql
Then you can ‘tar’ the .sql file with
tar -zcvf DATABASENAME-mysql.tar.gz DATABASENAME-mysql.sql
Backup just a single table
mysqldump db_name table_name | gzip > table_name.sql.gz
If you only want the database schema, then in the SugarCRM web application you can do the following:
Then for the restoration…
Restore ﬁles (to current folder):
tar -zxvf CRM-BACKUP-FILES.tar.gz
mysql -u USERNAME -p DATABASENAME < CRM-BACKUP-SQL.sql
Restore just a single table
gunzip < table_name.sql.gz | mysql -u username -p db_name

For when you’re trying to explain what the load average figure means (which you get from running either top or w from the linux command line) this link will help explain it easily. Easier than spending 10 minutes talking about it.
I wrote up how I’m numbering tasks in OmniFocus, but I’ve now modified the Keyboard Maestro recipe so it’s just a touch faster.
Here’s a screenshot:
I’ve also since created a separate recipe in Keyboard Maestro for each key Project I have in OmniFocus, each with it’s own .txt file that it refers to. This lets me do
and it’ll spit out “(Admin #7)” or if I type
it’ll spit out “(CRM #15)”.
I’m using OmniFocus 2 on my MacBook Pro and wanting to ‘number’ tasks because at the end of each week, I print a PDF of the tasks completed and outstanding for a particular client. Task numbers make it much easier for the client to reconcile the work I’ve done with the lists they use.
The problem is that OmniFocus doesn’t have a ‘task number’ function.
Keyboard Maestro and a shell script to the rescue. This allows me to get the next sequential task number. Now all I do is type
and it expands out to the next available task number.
In a nutshell I use the shell script to get a variable from a text file (which is the last task number I used), and increment it. Keyboard Maestro is wrapped around this to both trigger it and make it look pretty.
The shell script itself is quite basic, any improvements you can suggest, please do.
Here is a screenshot of the Keyboard Maestro recipe (edit: I’ve since modified this recipe to be a little faster)
This relies on you having a text file named
in your home folder.
The format of this file is just a single line of text as follows:
Find duplicate contact records, by contact name, in SugarCRM using MySQL.
This snippet of MySQL code shows how to concatenate two fields into one column, also shows how to reverse the concatenation and order by last name then first name.
Working on a SugarCRM dashboard today, and I needed to count how many records had one value and how many records had a second value. I then wanted to know what percentage the first value was of the total. So there’s a bit of MySQL code that helps make this easy to do.
SELECT SUM(IF(field_name = 'value_one',1,0)) AS 'Value One', SUM(IF(field_name = 'value_two',1,0)) AS 'Value Two' FROM table_name
What this does is counts up how many times
value_two appear in
field_name in the table
You can then take this a step further, if you wanted to, and I did…
you can use a line like this within your query:
This gives you the percentage that
value_one is of (

I was needing to navigate to a file that was in a ‘hidden’ folder, but the File Open dialog box won’t show the hidden folder.
The answer was found here: Press Command, Shift, Period keys together, the hidden folders/files will appear.

Just discovered the

srm will securely delete files, dependant on the switches you give it either one overwrite with random data, 7 passes, or 35 passes.
