Theming Slack for OSX

So, you love Slack, but you hate applications with large white backgrounds? Why not use Dark Mode!

Unfortunately, Slack does not have a Dark Mode, although it's on their list of possibilities.

But, don't fret - there is a solution! Because the slack native desktop apps are just wrappers around a web app, we can inject our own CSS to customize the application to our liking.

Keybase proof

I hereby claim:

  • I am michahell on github.
  • I am michahell ( on keybase.
  • I have a public key ASB8qALtw0hvE4VRNKqJloZZ1lXxsCXzrm8YCa2p4vsmDQo

To claim this, I am signing this object:


Virtuoso and some other SPARQL endpoint software extend the SPARQL 1.1 spec with some custom functions. one of them is free text search, which is INCREDIBLY much more faster than using regular expression text searches on, for example, DBPedia.

Here is an example SPARQL query for DBPedia using regex's :

SELECT DISTINCT ?film ?some_studio ?some_producer
    ?film rdf:type <> .
    ?film foaf:name ?film_title .
    FILTER regex(str(?film_title), "\\bArgo\\b") .

Viewing images in ST2

THIS Sublime Text 2 plugin

Enables you to view images from ST2 directly using a menu command or the hotkey combo CMD + SHIFT + SPACE. Since it uses the native OSX quick look functionality you can practically view anything that quick look can display!

TODO's in ST2

I've become used to adding TODO's since Flash Builder so i sought an alternative for sublime text 2, here among others. I've found one that's great and isn't tied to user- or application wide settings but can be project-specific: SublimeTODO. install it using the Sublime Package Manager and further instructions are to be found in the github readme.

MySQL SHOW databases alias

If you ever need to execute the following SQL statement in MySQL:

SHOW databases; or especially SHOW databases LIKE 'somePrefix_%'; and you want to alias or name the returned dataset, you can't do that with the SHOW statements as they are very limited. You can however do this if you make use of the INFORMATION_SCHEMA default MySQL table:


You're welcome!

You can’t perform that action at this time.
