Round avatars, thumbnails, and other images

Lately I learned how images can be rounded using CSS. This seems to be a "good formula":
.someclass {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
}
For some templates, and maybe just for a change, those rounded images can look very good. I'll show you CSS you can add to my hacks, and one Blogger gadget, to make images round. In my hacks you should add the CSS in the code before </style>.

Better recent comments gadget

Add this style:
.recent-comment-ico img {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
}


Profile gadget with post count

Add this style:
.author-avatar {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
}


Top Commentators gadget

Add this style:
.top-commenter-line img {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
}


Gadget for YouTube activity feed

This gives a nice "tube TV" like effect, add this style:
div.ytc_thumb img {
border:none;
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
}



Just one more, and I think you'll get the hang of it. :)

Popular Posts (Blogger gadget)

Add this style using Template Designer, Advanced, Add CSS:
.PopularPosts .item-thumbnail img {
-webkit-border-radius: 100px;
-moz-border-radius: 100px;
border-radius: 100px;
-webkit-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
box-shadow: 0 1px 3px rgba(0, 0, 0, .4);
}

Profile Gadget with avatars and post counts

This is especially for multi author blogs. In multi author blog the profile gadget is very simple looking. It only contains author names in <ul>/<li> list. There is "avatar" but that is the default blogger logo.


My multi author blog profile gadget looks like this:


It works on single author blogs, too, and one could customize it to look about the same as the default single author blog profile gadget, but I'll leave that for you as an exercise. :)

Installation is simple. Add HTML/Javascript gadget into your blog, and paste the following code there:



You can configure some things in the script: maximum user name length, author line template, avatar size, and is avatar cropped or streched. As always, you can also modify the CSS to your liking.

This was "thrown together" very quickly, but it works ok so I decided to publish it. Hope you like it.

Customizable Author Box with post count

I got this request for an author box with post count in my blog's comments. An author box is something that is displayed after a post, and it shows info about the author who wrote the post. WordPress.org has many author box extensions, for example Author Box After Posts. There are some hacks for Blogspot blogs, too, but they are generally for single author blogs, and with no post count.

My Author Box has support for blogs with multiple authors, and post counts per author.


I must warn you, this hack suits best people who can do their own template customizations and basically already know their way around. These instructions have worked "as is" for Simple and Awesome templates, should work for all others, too, especially if you know you to adapt the code. Not for dynamic templates, though.

How to install

Installing is quite simple. Edit template HTML, expand widget templates. This hack uses jQuery, so if your template does not already have jQuery, add the following code in your template before </head>:
<script src='http://code.jquery.com/jquery-latest.js' type='text/javascript'></script>

Then find: <data:post.jumpText/>, there should be only one instance. Few lines down from there is line:
<div class='post-footer'>
just before that line paste all this code:



This (+ possibly jQuery loading) is the only code you need to put into the template. Later I'll show you three snippets from this same code, don't put them in the template, just edit the previous code at those points. After pasteing the code to the template, you can save the template and see if there were any errors. You can also test the hack at this time. After that you must customize the hack to suit your blog and blog's authors.

Configuration

This hack works for both single author and multi author blogs. If you have multi author blog, you must set var multiAuthor = true; This setting can be true for single author blogs, too, but it is sligthly faster if you put false there for single user blogs.

With onePost and manyPosts variables you can localize the words "post"/"posts" or use other word like "article"/"articles".

There are more configurable things in javascript parts, but I'll tell more about them later.

HTML markup

This part defines the look of author box.



Author box html comes partly from the template, and author specific thigs are set by javascript. If you have a single author blog, you can put basically any html between <div class='post-author-block'> and </div>.

Just use <span class='authorinfopostcount'>0</span> where you want the post count to appear, and <span class='authorinfopostpost'>posts</span> where you want the singular/pluralis post word to appear. You can also use the same classes as in multiple author blogs, and you can use additional classes and make CSS for them as you wish.

With multi author blog, author specific information contains post count, author (profile) link, author avatar image, author description, and author name. So these can not be "hard coded" into the box, but they are set via javascript. Inside <div class='post-author-block'> and </div>, when you use the following tags + classes, their contents will be dynamically set:

<a class='authorinfolink'>somemarkup</a> this will link the text "somemarkup" to author profile link
<img class='authorinfoimage' src=''/> this will get author avatar
<span class='authorinfoname'/></a> author name will be put inside this span
<span class='authorinfopostcount'>0</span> and post count here
<span class='authorinfopostpost'>posts</span> this will be post/posts (singular, pluralis) according to how many posts author has
<span class='authorinfodescription'></span> this will be replaced by the author specific description, which can be plain text or complex html (but no scripts). Class can be used in div, too.

You can also add classes and CSS for elements if you wish. It is just basic template editing. And probably want to customize the CSS too, to get the box look like you want. CSS part is this:



Then in the javascript part, for every author or the blog you should set variable aut_desc['AUTHORNAME']. Element with class='authorinfodescription' will receive that description. You can use html here, put div's there, br's, links, imgs, pretty much everything, but not scripts. Now there is only some info about me and some dummy info, you can replace them with content that is relevant to your blog.

For every author or the blog you can (but it is not necessary) set/override auth_url['AUTHORNAME']. This way you can link author straight to his Google+ profile, or any other page you wish, instead of the blogger profile page. Here's the configuration part of the javascript:



I would have liked to get the author description automatically, but there is no feasible way of getting author profile descriptions in multi author blog, so the descriptions must be set in script. Positive side is that you can use any description you want, with links, images etc. Because descriptions could not be fetched automatically, I decided to leave the whole hack simple, so its users can customize the author box look themselves.

If anyone wants to develop this idea further, go right ahead. I'm not so good at making html/css, some of you will make this look much better. If you use it, please drop a comment so I can see what it looks like in your blog. :)

Hack for my recent comments hack: don't show own comments

Maybe you don't want to show your own comments in recent comments? Here is quick and simple hack for my Son of the better recent comments gadget to make it not show own comments.

Edit the HTML/Javascript gadget. Change lines 93 and 115, which both look like this now:
var entry = json.feed.entry[i];
to:
var entry = json.feed.entry[i]; if(entry.author[0].name.$t=="PUT YOUR USERNAME HERE") continue;
Edit your username inside the quotation marks. Save the gadget. Your comments won't be displayed anymore in recent comments.

Extending Yahoo! Pipes with Google App Engine

In my Uploads and Favorites pipe I wanted to turn the timestamps into so called "humanized dates", like these six examples:

23 seconds ago
1 minute ago
4 hours ago
2 days ago
7 months ago
1 year ago

This could not be done by using only Yahoo! Pipes.

Google App Engine to the rescue

Yahoo! Pipes can be extended using a web service, which accepts the feed items as json, and outputs them (after changes) as json. I used this blog article Using Google App Engine to Extend Yahoo! Pipes as a starting point. Django framework has date humanizing functions coded in Python, and I borrowed those functions from there. Then I created a new Google App Engine application "humandate", and made files app.yaml and humandate.py.

app.yaml



humandate.py



I put these two files in a directory called "humandate" under my Google App Engine directory, with favicon.ico (the GAE default icon), and the development environment is ready. I now can deploy the application using "./appcfg.py update humandate/" or test it locally using "./dev_appserver.py humandate/", then the app runs at http://localhost:8080.

Testing the date humanizer

I made also an url based interface to "humandate" in addition to Yahoo! Pipes json interface. Url based interface works by giving a unix timestamp as "unixtime" parameter, like this. This made testing the date humanizer easier.

Using the service in Yahoo! Pipes

This service expects items to have y:published.utime field present. Service reads it from every item, turns it into a humanized date, and makes a new field "when" containing the humanized date. Then the service returns the items back to pipes.



See also my previous article about the four youtube pipes I've made (one of them uses this humandate, and one uses it indirectly). And have fun with Google App Engine and Yahoo! Pipes.

Yahoo! Pipes, pipes, and more pipes for YouTube

Lately I've been playing around with Yahoo! Pipes and learned some new things. I already presented the YouTube Activity Feed, which I've cleaned up a little. And I've made three more pipes.


YouTube Activity Feed

Pipe ID: 58c841d14337ba4fbf693abd9701dc49
Pipe Web Address: http://pipes.yahoo.com/mspotilas/youtubeactivityfeed

Here's my previous article about this feed. YouTube API 2.0 does provide activity feeds, but you need to register an application to get developer key. My idea was to read the same info from user's channel feed page in html, parse the html and republish as a feed, and YouTube Activity Feed pipe does that.

As html parsing is quite complex task, if YouTube changes the feed page structure a lot, this pipe might break. I'll probably try to fix it if that happens.


YouTube Likes Feed

Pipe ID: a58d86555f7eb396e73d58ff50edc8f1
Pipe Web Address: http://pipes.yahoo.com/mspotilas/youtubelikesfeed

Same idea as in Youtube Activity Feed, but it gets only "liked videos" from the channel feed page. It is a bit simpler to parse only the likes. Also with this pipe, if YouTube changes the feed page a lot, the pipe might break.


YouTube Uploads and Favourites

Pipe ID: 0c2ee991c8d94ed0ceb19865c252e047
Pipe Web Address: http://pipes.yahoo.com/mspotilas/youtubeuploadsfavoritesfeed

YouTube has gdata feeds for user uploads and user favorites.

http://gdata.youtube.com/feeds/base/users/USERNAME/uploads?alt=rss&v=2
and
http://gdata.youtube.com/feeds/base/users/USERNAME/favorites?alt=rss&v=2

This pipe combines these two feeds, descriptions will be for example "2 days ago USERNAME favorited" or "1 hour ago USERNAME uploaded". The tricky part was to get this humanized date "2 days ago" derived from feed item's timestamp. It could not be done in Pipes only, so I extended its functionality with a web service I coded into Google AppEngine. It goes through the list, converts "y:published.utime" to humanized date like "2 days ago" and stores it in field "when" and returns the list back to pipes. Here's an article about the web service: Extending Yahoo! Pipes with Google App Engine.

This pipe should be robust, as it uses feeds as source, not page html.


YouTube Feed

Pipe ID: 73c5ee4a46e1837d908deaa60b1858d2
Pipe Web Address: http://pipes.yahoo.com/mspotilas/youtubefeed

This fourth pipe simply combines Uploads and Favourites and Likes Feed. Structure is very simple. Output is something similar to YouTube Activity feed, but it does not contain comments, playlist additions nor channel subscriptions. But sometimes simpler is better.


All pipes are compatible with my gadget which works also on Opera (Yahoo! Pipes badge does not). Just change the pipe ID (_id) to use a different pipe.

Feel free to examine these pipes, you can also make clones which you can modify. Comments are welcome, too. :)

Another gadget for YouTube Activity Feed, works with Opera

Few days ago I finished making my first Yahoo! Pipe, which collects info from YouTube channel feed page, and republishes that info. Yesterday I noticed, that Yahoo! Pipes badge output does not support Opera – with Opera, nothing is shown. It is strange that Yahoo does not fix this, maybe it is because Pipes is a free product. About 3 % of my blogs readers use Opera.

I knew I could make a gadget that works on Opera, too. Yesterday evening I coded first a javascript version, and today morning a little tidier jQuery version.


Installation is simple: add an HTML/Javascript gadget and put the following code in it:



You can leave out the first line, if your template already loads jQuery. Make necessary configuration changes (change YouTube user name, for example). I did only very basic CSS, you can of course modify it to your liking. Code can be used also outside Blogger (in any html page).
