This is due to there being two clipboards, the one belonging to the Mac and the one in Emacs (the kill ring).

Often I would use one or the other and get the wrong pasted contents. Then I’d have to stop, back up, and find the original contents and do it again. Worse, sometimes the contents would be cut or killed, meaning that I would have to undo the cut/kill, redo the cut/kill, then yank/paste.

Well, I finally had enough and looked for ways to harmonize the two clipboards via the .emacs file. Here is what I came up with:


(defun swap-and-kill ()
"Swap point and mark, then clipboard kill region"
(interactive)
(exchange-point-and-mark)
(clipboard-kill-region (region-beginning) (region-end))
(deactivate-mark)
)
(global-set-key "\C-w" 'swap-and-kill)
(global-set-key "\M-w" 'clipboard-kill-ring-save)
(global-set-key "\C-y" 'clipboard-yank)


Now everything goes to the Mac clipboard, even if I use my beloved mark and point with C-w.

I found most of the clues for this solution here:

var str1 = "Here is a sentence that just seems to go on and on. Here is a sentence that just seems to go on and on. Here is a sentence that just seems to go on and on.";
var str2 = str1.replace(/(([^\s]+\s\s*){20})(.*)/,"$1…");
document.write(str2);
// result:
// Here is a sentence that just seems to go on and on. Here is a sentence that just seems to …



function findParentNodeRegex(regex, childObj) {
var testObj = childObj;
var count = 1;
while(!testObj.id.match(regex)) {
//console.log('My name is ' + testObj.id + '. Let\'s try moving up one level to see what we get.');
testObj = testObj.parentNode;
count++;
}
// now you have the object you are looking for - do something with it
//console.log('Finally found ' + testObj.id + ' after going up ' + count + ' level(s) through the DOM tree');
return testObj;
}


Suppose that you tapped an paragraph element that was nested like so and “target” points to the paragraph:

<div id="news1234"><div class="content"><p>Tap me!<p></div></div>

You can find the parent that matches the string “news” like so:

var newsParent = findParentNodeRegex(/news/,target);
console.log("Id is "+newsParent.id); // prints "Id is news1234"

I adapted the code from here

<div id="promovid">
<video id="video" controls="controls" poster="video-poster.jpg" preload="none" width="640" height="480">
...
</div>


Them to make the poster frame clickable, I used this jQuery snippet:

<script>
$(document).ready(function(){
$('#promovid').click( function(){
$('#video').get(0).play();       // get(0) gets the original DOM element
$('#promovid').unbind('click');  // remove click listener
});
</script>

Notice that I remove the click listener after the first click. This viewer can then use the native controls to pause or fullscreen the movie.

Also note the use of get(0) on the $(’#video’) element. My first inclination was to say $(’#video’).play(). However, jQuery elements don’t usually expose the methods of the selected DOM element. To access the actual DOM element, I had to use get(0).

I had some wiring connected to digital ports 0 and 1 (TX and RX) and that was causing communication errors. I unplugged the wires to those ports and the upload then worked just fine.

Flipboard is a compelling concept… it displays news from your Facebook account and any number of Twitter accounts in a magazine style format. That means large Helvetica headlines, easy to read Times content, and lot’s of photos.

But it doesn’t (yet) support RSS feeds as a source. Flipboard says they will at some point.

I wonder though if it is even necessary. I wanted to create sections for some of my favorite sources… Jay Rosen and Dave Winer for media commentary, Techmeme for tech stuff, and Against Dumb, for variety.

It turns out that they all have Twitter accounts. Those accounts typically link to all the same content that their RSS feeds do. Often more, because they will contain links to content that the authors find interesting, but that don’t appear in their RSS feeds.

And guess what. Twitter accounts are much easier to work with than RSS. Here’s why:

• Twitter accounts have names that are easy to find, remember and refer to. People can even talk about them.
• RSS feeds are links. They are technical. No one talks about them in normal discourse.
• Posting to Twitter is easier than adding to RSS. Even with Wordpress around.
• Twitter accounts are easy to aggregate into lists.

I understand that Twitter has a different intent than RSS, and that RSS provides much of the foundation of information flow on the internet.

But I just wonder if Twitter is ending up to be a much easier way to say “here’s what’s new… and interesting”. And if it’s easier, then why use RSS?

The solution was to use a Javascript redirect. The Javascript attaches an event listener to listen for the “load” event. When the admin page is finished loading, a page containing the CSV data is loaded. That page has a Content-Type of application/csv, so it downloads immediately, leaving the admin page open (at least in Safari 4).

In my Wordpress admin panel (this is a fragment of a plugin):
// setup Javascript redirect
$location='/wp/csv-output/?year='.$year.'&month='.$month;
?>
<script>
function addListener(element, event, listener, bubble) {
if(element.addEventListener) {
if(typeof(bubble) == "undefined") bubble = false;
element.addEventListener(event, listener, bubble);
} else if(this.attachEvent) {
element.attachEvent("on" + event, listener);
}
}
addListener(this, "load", function() { window.location="<?php echo $location ?>" });
addListener(document, "load", function() { window.location="<?php echo $location ?>" });
</script>
And in my CSV page (again, just a fragment):
ob_end_clean();
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=contact_data_$year_$month.csv");
header("Pragma: no-cache");
header("Expires: 0");
I found the javascript code here.

<form ... onsubmit="setTimeout('document.forms[0].submit()',2000);return false;">

but everytime I tried it, I got the following error:

Result of expression 'document.forms[0].submit' [[object HTMLInputElement]] is not a function.

This one had me stumped, until I realized what it was telling me… that my submit button was named “submit”.

<input type="submit" name="submit" id="Button1" />

I changed the name of the submit button and the problem went away.

<input type="submit" name="button1" id="Button1" />

Basically, Javascript provides a “convenience” by adding the names of the form inputs as children of the form. But this then clashes with preset function names, like the submit() function.

John mentions that the tools to create the e-book is based on standard web tech: HTML, CSS, and Javascript. My guess is that some day, not too long from now, we will see something like Pages (or maybe GarageBand) for iTunes where you can create your own digital creations and submit them to the iTunes store. It will probably dwarf the App Store in total volume.

Update: ReadWriteWeb has more to say about this.

One misconception about RSSCloud is the supposed need for the cloud to notify the desktop or mobile reader of an update. This would seem to mean that you would have to adjust your firewall to accept inbound connections to your computer/mobile device.

While the implementor’s guide shows that the cloud does notify the aggregator, the aggregator doesn’t have to be the same as the reader. As the guide suggests, the aggregator can also be in the cloud, with the reader opening an outbound connection to the aggregator, in the same way AIM or Skype or Jabber clients do, using protocols like XMPP. No need to adjust your firewall.

For that matter, Twitter clients do the same thing, using HTTP REST calls. The only difference is Twitter limits the number of API calls per hour (currently 150 requests per hour, or 2.5 requests per min–close enough to realtime for me), while there are no limits with XMPP. The tradeoff is arguably one of simplicity – is your client easier to implement with one or the other?

Hopefully the folks working on RSSCloud are developing an example of a cloud aggregator and an associated protocol. My vote would be for the protocol to be REST-based, but I could be convinced otherwise.
