Migrate from Delicious to Diigo

Delicious set the standard but they’ve been a bit of a bumpy ride lately with reliability… according to their blog.delicious.com they recently moved back to old code base and Del.icio.us domain (ah memories :)… and then just as of today just got their settings page operational such that I could successfully export my bookmarks.
 

Diigo.com looks very slick so i’ve been using that lately – nicely robust Chrome plugin.
 

Here’s a little JS i threw together to truncate my Delicious links at a certain date.
Edit the exported html file and add jquery in the head and reload

<head>
  <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.3/jquery.min.js"></script>
</head>

then run this JS straight from the developer tools console in Chrome, or whatever you prefer

// this approach works on "bookmark file" format. e.g. what Delicious.com exports
// basically just an html file full of <a> tags wrapped with <dt>'s inside one big <dl>
// key attributes: ADD_DATE="1461441710" TAGS="BestStuffEver"
// the date format is in seconds... to make it JS Date compatible just multiply value by 1000 (i.e. milliseconds)

// find the "add_date" of the oldest entry you want to keep
var cutoffDate = new Date(1345307846000)

// this then deletes all the links older than cutoffDate
$("a").each(function(idx, el) {
  if( new Date($(el).attr("add_date")*1000) < cutoffDate ) { var par = $(el).parent(); par.next("dd").remove(); par.remove(); }
});

// then just save-as that page

// and import to Diigo :)

         $conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
    }
    catch(Exception $e){
         die(var_dump($e));
    }
    
    $stmt = $conn->query($qry);
    $result = $stmt->fetchAll();

PHP7 Debugging under Visual Studio 2015

I suggest installing PHP7 through the IIS Web Platform Installer so it does the Handler Mapping vs having to mess with that manually (i.e. assigning PHP extension to php-cgi.exe) – but there’s a lot of guides out there for doing that yourself if you want. That’ll probably leave you with a slightly older version so then just go install latest PHP7 bits over the top – we want the non-thread-safe (NTS) builds when running under IIS FastCGI (supposedly the most performant approach) Ideally you don’t mind springing for PHP Tools for Visual Studio… this package provides comforts like Intellisense and PHP project templates… and I also noticed that PHP Tools automatically configures XDebug debugging bits for us which is nice vs figuring that out manually (at least the first time)… turns out its just some php.ini settings (see below). so basically you just launch site in Visual Studio debug (F5) and PHP Tools will ask you if you want it to configure debugging for you… the brief wrinkle here is that it then went off and installed/configured PHP5.x… hence the main reason I’m posting this – to affirm we can then indeed just go copy the pertinent settings from the PHP5.ini to our PHP7.ini… if you go look at the php5.ini that PHP Tools set up you’ll see the following settings added at the bottom (for me it went under: C:\Program Files (x86)\iis express\PHP\v5.6): [XDEBUG] zend_extension=”C:\Program Files (x86)\IIS Express\PHP\v5.6\ext\php_xdebug.dll” xdebug.remote_enable = on xdebug.remote_handler = dbgp xdebug.remote_host = 127.0.0.1 xdebug.remote_port = 9000 xdebug.remote_mode = req so then we need to go get xdebug for php7

Free SSL Certs

LetsEncrypt.org is a wonderfully progressive initiative… free certs for all, to promote better internet security, nice!
 

this windows tool made quick work of plugging it into IIS vs the more unix’y stuff they suggest on their home page
literally just seconds to launch the win tool and hitting a key to select which IIS site you want the cert for… none of the ol’ CSR hassle, yay!
 

Tips:

  • your web server has to be reachable on the public internet at the domain url (port 80) you wish to gen the cert for
  • the win tool will be most automatic when you plug your domain into the host-header (port 80)

Note: The LetEncrypt certs come set to expire in 90 days but I saw some talk of auto-renewal… not yet sure if that requires scripting or not.

Knockout-Validation lib – clean patterns

GitHub home

leverages the jQueryValidation lib

All Bootstrap v3 compatible

Coolest architectural nugget = applying validation rules to VM observables (not inside HTML <input> markup)

one clear reason why that is a better way -> when the VM field is bound to multiple UI points, you only define the rule once vs many

var myVM = function() {

    var self = {};

    // simple required
    self.orderId = ko.observable().extend({ required: true });

    // conditionally required
    self.orderId = ko.observable().extend({ required: { onlyIf: self.isDelivery } });

    // required with field name in error message - LUVIN HOW SIMPLE THIS IS!
    self.orderId = ko.observable().extend({ required: "Order#" });

    // conditionally required with fieldname
    self.orderId = ko.observable().extend({ required: { params: "Order#", onlyIf: self.isDelivery } });

    return self;
}();

WordPress – show all Tags in Cloud

wordpress defaults to only showing the first 45 tags
tweak this file => \wp-includes\widgets\class-wp-widget-tag-cloud.php
add the “number=0” parameter to this code:

    /**
         * Filter the taxonomy used in the Tag Cloud widget.
         *
         * @since 2.8.0
         * @since 3.0.0 Added taxonomy drop-down.

Knockout HTML5 Canvas Signature Capture

See the Pen Knockout HTML5 Canvas Signature Capture by Brent Anderson (@Beej2020) on CodePen.




Knockout, Validation, Bootstrap skinned File Input

Visual example:


 
Highlights:

  • Skinning the native html <input type=”file”> by setting it’s opacity=0 and positioning above a bootstrap looking button… this way when you click the pretty button you’re really clicking on the invisible native button which launches the file open dialog.
  • Bootstrap input-group aesthetically bundles the visual elements – file button, filename box, valiation message and clear button
  • Knockout Custom Binding on the file input change event to save into VM observable
  • Knockout-Validation lib to require selected file to be an image type – nice thing here is keeping that logic in the js ViewModel vs dirtying the html with it.

HTML5 Canvas based 3d Tag Cloud

This Goat1000.com guy has provided an amazingly comprehensive 3d library… the configuration options are endless.

<!--[if lt IE 9]><script type="text/javascript" src="excanvas.js"></script><![endif]-->
<script src='//www.goat1000.com/jquery.tagcanvas.min.js' type='text/javascript'/>

<script type="text/javascript">
  $('#canvas3dTagCloud').tagcanvas({
    textColour : '#000',
    outlineThickness : 2,
    maxSpeed : 0.03,
    depth : 0.75,
    zoom: 1.15,
    weight: true,
    weightFrom: "data-weight",
    weightSize: 5
  });
</script>

Below needs to be edited for your particular blog engine’s syntax for looping over tags.

<canvas height='272' id='canvas3dTagCloud' width='272'>
  <p>Anything in here will be replaced on browsers that support the canvas element</p>
  <ul><b:loop values='data:labels' var='label'> <!-- this is google blogger syntax for looping over the label values -->
    <li><a expr:data-weight='data:label.cssSize' expr:href='data:label.url'><data:label.name/></a></li>
  </b:loop></ul>
</canvas>
