Coach, Mentor, Strategist

I’m Harry Bailey and I help foster tech teams and the humans who help form and fuel them. My work creates better outcomes, more value, happier humans and solid autonomous teams.

I work with companies of all shapes and sizes who are struggling to make Scrum, SAFe and other agile frameworks work for all areas of their business.

My experience as an agility coach, product owner, business owner, tech strategist and software developer enables me take a team-focused approach. I look to support value creation at every level from pair coding through to business strategy.

Some describe my role as Delivery Coach and some as Agile Coach. My preference is Agility Coach. ‘Agile’ isn’t something to be achieve, and our focus as members of software development teams should be on removing the impediments that limit agility. I work with teams of all sizes and experience levels to be better tomorrow than they are today.

CSS3 Element Wiggle With Keyframes

This technique produces something similar to the wiggle you get on an iPhone when deleting items.

Be aware that keyframe animation is still very poor in Chrome and cases freezing and jumping if multiple items are animated at once.

The animation css below results in a hovered element rotating back and forth around it’s centre point. You can update the number of degrees and length of animation to change the appearance.

Just add this css and give your element the class ‘wiggler’ to implement

/* safari and chrome */
@-webkit-keyframes wiggle {
	0% {-webkit-transform:rotate(4deg);}
	50% {-webkit-transform:rotate(-4deg);}
	100% {-webkit-transform:rotate(4deg);}
}

/* firefox */
@-moz-keyframes wiggle {
	0% {-moz-transform:rotate(4deg);}
	50% {-moz-transform:rotate(-4deg);}
	100% {-moz-transform:rotate(4deg);}
}

/* anyone brave enough to implement the ideal method */
@keyframes wiggle {
	0% {transform:rotate(4deg);}
	50% {transform:rotate(-4deg);}
	100% {transform:rotate(4deg);}
}

.wiggler:hover {
	-webkit-animation: wiggle 0.5s infinite;
	-moz-animation: wiggle 0.5s infinite;
	animation: wiggle 0.5s infinite;
}

Reordering Yii Results Without Another Select

In case you weren’t aware, you can reorder the results you already have from a previous Yii call. For example…


$users = User::model()->findByPk(2);
$posts = $user->posts(array('order'=>' created Desc '));

There were just ordered our users posts by created date descending.

We can also do filtering…


$users = User::model()->findByPk(2);
$posts = $user->posts(array('condition'=>' status=1 '));

So now we only have active posts. We could also combine a condition and a status.

You can find out more here: http://www.yiiframework.com/doc/guide/1.1/en/database.arr#dynamic-relational-query-options

Twitter Bootstrap Tabs On Right Side

Twitter’s bootstrap css currently doesn’t support tabs on the right hand side or floated right. We’ll here is the css to allow it.

We’ll stick to existing naming. Twitter use secondary-nav within topbar so let’s use that…

.tabs .secondary-nav {
	float:right;
	margin-left:10px;
	margin-right:0;
}

The the html for the tab you want to float right you need:

The outcome is most tabs on the left and any with the new class positioned over to the right.
