Flyte Is A LightBulb That Levitates, And It’s Cool - zo, 26/04/2015 - 12:01

What is the first thing that comes to mind when you see this? Let me help: How is this light bulb floating on top of that base? Secondly, what in blazes is keeping this lightbulb lit up?


Well, the magic of magnetic levitation and wireless power transmission, to be precise. That LED lightbulb is held afloat by an electromagnet, and it is lit up wirelessly – look ma, no battery or power cables.

This, is the Kickstarter project, Flyte: Levitating Light. Flyte is a shatterproof, energy-efficent LED lightbulb that shines at 60 lumens, and is designed to fit into a cafe, home or office setting.

The bulb is supposedly good for 50,000 hours (or 22 years at 6 hours a day) – basically, you probably don’t have to change this lightbulb. The 7.9 x 7.9 x 1.4 in base is available in sustainably sourced walnut, oak and ash. There is also a limited-edition, handcrafted diamond-shaped wooden base.

Once the bulb lights up and levitates, it rotates slowly above the center of the base, much like an art installation you would see at an art gallery. To turn the light on or off, just touch the base lightly with your finger.

The best part about this is that the base for Flyte has a second use as a wireless charging base, though you will need third party accessories. To start charging, just place the phone on the base, that’s it.

How To Get Flyte

Flyte: Levitating Light reached their goal of $80,000 within 2 days and at the time of this writing, has secured $140,000 worth of pledges. The lowest pledges are now at $249. The first batch will be delivered in October of 2015. You can also opt to pledge for the Flyte makers Kit which allows you to build your own levitating object.

How to Install Windows Boot Camp Without An Optical Drive - vr, 24/04/2015 - 15:01

Editor’s Note: Previously, we published a post by Daniel Pataki on How To Install Windows on Mac when all else fails. Alvaro is one of the many readers who left a comment on that thread. Below is his version on how to get Windows Boot Camp, and thus, Windows, on your Mac.

I have a late 2009 27" iMac which has a built-in Optical Drive, one that is not operational anymore. I’m not sure why it refuses to work, but I tried cleaning it with canned air, which improved its condition a little because now at least it "swallows" the dvd and spins it – it just never recognises it. I also have a MacBook Air which I successfully installed Boot Camp on with the use of an external drive. Still, I wanted a way to install it without the drive.

What Didn’t Work

So I tried lots of things.

The first one, was enabling the Boot Camp Assistant app to create bootable USB drives. It didn’t work, because after the application created the USB drive, it made a partition and rebooted. I was supposed to see the windows installer, but instead, all I saw was a blinking white line on a black screen. After several minutes of this, I gave up and force-booted my computer.

Next, I tried creating a partition on my own, using disk utility, formatting it as FAT32 and then attempted to boot from the USB. This did not work either. When I booted my Mac in the boot option menu, it did not show the partition, nor the "bootable" USB.

And that’s when I found this tutorial by Daniel Pataki, which I tried on my MacBook Air and it worked like a charm, despite the long and complex process. When I tried it on my iMac, however, things didn’t go well. When I tried to boot the VM from the Boot Camp partition and install windows, the VM booted into a black screen saying "Missing Operative System".

Finding Plan B

I had given up on other methods, and I decided to sleep on the problem of installing Boot Camp on my Mac when I suddenly thought about the Apple Watch. You see, what Apple has always wanted is for us users to buy a new model of Mac whenever the older one cannot do something. It’s the answer to why certain Mac models can create bootable USB drives while others can’t.

I then asked myself if USB drives have the same restrictions. One thing led to another and this is the way I install Windows on My Mac now. And it is way, way easier.

What Did Work

Here’s what we’ll be doing:

  1. Create a Bootable USB
  2. Create Partition
  3. Install Windows

Yes, it’s really that simple.

Create a bootable USB

1. Locate a Windows PC.

2. Download two things: a Windows 7 USB download tool directly from Microsoft, and a full Windows ISO of the version you want to install.

3. Open the Windows 7 USB download tool and browse to your ISO file, click continue and follow the instructions in the next section to create your Bootable USB.

Create a Windows Partition

We will be using Boot Camp Assistant.. well, sort of.

1. First, we need to make the application recognise USB drives. Go to Finder > Applications > Utilities, and right click on Boot Camp Assistant, then click "Show package contents".

2. Navigate into Contents, locate the "info.plist" file then make a copy (do not move the original) of it to your desktop. If you like, make another copy as a backup, just in case something goes wrong.

3. Open the "info.plist" file located on your desktop, look for the line of text saying PreUSBBootModels and erase the "Pre" from there, save the file (CMD+S) and close it.

4. Drag the modified info.plist file from your desktop to the Contents folder we opened previously. It will ask you to Authenticate with your administrator Name and Password. Click Replace.

5. If you were to open Boot Camp Assistant now, and it crashes, that’s because it detected that a modification has been made. If this happens, open terminal and type the following command:

sudo codesign -fs - /Applications/Utilities/Boot\ Camp\

Enter your Administrator Password and hit enter. Now you can open Disk Utility.

6. Make sure your Bootable USB is plugged in. Open Boot Camp Assistant and you will see 3 options.

Check Install windows, and hit continue, select the size you want to dedicate to windows and click Install. The process might take several minutes.

Install Windows

Once the Partition is ready, your computer will restart into the Windows installer, follow all the instructions, and enjoy your new windows partition!

Remember that when you finish the installation process, you should download and install the proper Boot Camp Support Drivers so that everything works perfectly.

44 Handwriting So Neat And Beautiful You’d Be Jealous - do, 23/04/2015 - 15:01

For all our readers out there who are no longer students, we need to ask, when was the last time you held a pen? If you still do, when was the last time you’ve actually penned something that is not limited to signing your name on a credit card purchase?

For these masters of the handwritten note, writing by hand is almost a skill that is forbidden to have. I mean, just look at some of the mind-blowingly amazing way people are stringing together essays, math formulas and equations, lesson notes and thank-you cards with no grids or rulers, just tons of patience, highlighters and paper.

Using and Styling HTML5 Meter [Guide] - di, 21/04/2015 - 15:01

If you’re familiar with the HTML progress bar, which shows how much of an activity has been performed, you will find that the meter element is similar to that – both show a current value out of a maximum value. But unlike the progress bar, the meter bar is not to be used to show progress.

It is used to show a static value in a specific range, for example you can indicate the storage space used in a disk storage by showing how much of the storage space is filled and how much is not.

On top of that, the meter element can also be used to visualize up to three regions within its range. Reusing the storage space example, instead of only showing how much space is occupied, you can also visually indicate whether the occupied space is only sparsely filled (lets say below 30%) or near half full (between 30 to 60%) or more than half full (above 60%) using different colors. This helps the users know when they are reaching the storage limit.

In this post, we’ll show you how to style the meter bar for both purposes mentioned i.e. a simple gauge (with no indicated regions) and two examples of gauges with 3 color-indicated regions. For the latter, we will work on creating a "marks" gauge for showing poor, average and good marks, and a "pH" gauge for showing acidic, neural and alkaline pH values.


Before we start with the examples and go in-depth, let us take a quick look into its list of attributes below, more about these attributes like their defaults, etc. will be covered in the examples.

  • value – The value of the meter element
  • min – The minimum value of the range of the meter
  • max – The maximum value of the range of the meter
  • low – Indicates the low boundary value
  • high – Indicates the high boundary value
  • optimum – The optimum point in the range
1. Styling A Simple Gauge

Here’s a very simple example using only one attribute, the value. Before we proceed, we need to know three things first:

(1) There is a default min and max value defining the range of meter, which is 0 and 1 respectively.
(2) If the user-specified value does not fall within the meter range, it will take the value of either min or max, whichever it is closest to.
(3) The Ending tag is mandatory.

Here is the syntax:

<meter value="0.5">0.5</meter>

Alternatively, we can also add min and max attributes thus providing a user defined range like so:

<meter min="10" max="100" value="30"></meter> 2. Styling The "Marks" Gauge

First, we need to divide the range into three regions (left/low, middle, right/high). This is were low and high attributes come into play. This is how the three regions are divided.

The three regions are formed between min & low , low & high and high & max.

Now it is obvious that there are certain conditions low and high values should follow for the three regions to be formed:

  • low cannot be less than min and greater than high & max
  • high cannot be greater than max and less than low & min.
  • And when a criteria is broken both low and high will take on the value of the other variable in the criteria which is not satisfied, i.e. if low value is found lower than min which it shouldn’t be, low will get the min value.

In this example, we will consider our three regions from left to right to be:

  • Poor: (0-33)
  • Average: (34-60)
  • Good: (61-100)

Hence, the following are values for the attributes; min="0" low="34" high="60" max="100".

Here is an image visualizing the regions.

Even though there are three regions in the meter we created just now, it will indicate only two "kinds" of regions in only two colors at the moment. Why? Because optimum is in the mid-region.

Optimum Point

In whichever region (of the three) the optimum point falls in, it is considered as an "optimal region" colored green by default. The region(s) immediately next to it is called the "sub-optimal region" and it is colored orange. The one farthest away is a "not-much-of-an-optimal region", colored red.

So far in our example we have not assigned a value for optimum. Hence, the default value becomes 50, making the mid-region the "optimal region" and the ones right next to it (both on the left and right) as "sub-optimal regions".

In short in the above case, any value to the meter element that falls into the mid-region is indicated by green; the rest orange.

That’s not what we want. We want it colored this way: Poor (red), Average (orange), Good (green)

Since the right-region is to be considered our optimal region, we will give optimum a value that will fall into the right-region (any value between 61-100, including 61 & 100).

We’re taking 90 for this example. This will make the right-region "optimal", the middle (its immediate next region) "sub-optimal" and the far left the "not-much-of-an-optimal" region.

This is what we will get on our gauge.

2. Styling The "pH" Gauge

First, a breather on pH values. An acidic solution has a pH of less than 7, an alkaline solution has a pH of greater than 7 and if you land on 7, that’s a neutral solution.

Thus, we will use the following values and attributes:

low="7" , high="7", max="14", and the min will take the default value of zero.

Before we add the rest of the attributes to complete the code, let us decide on colors: Acidic (red), Neutral (white) and Alkaline (blue). Let us also consider the acidic region (left-region below 7) as "optimal"

Here are the CSS pseudo elements we will target to get the desired visual in firefox. (For the webkit meter pseudo elements and more, refer to the links listed under "reference".)

.ph_meter { background: lightgrey; width: 300px; } .ph_meter:-moz-meter-optimum::-moz-meter-bar { background:indianred; } .ph_meter:-moz-meter-sub-optimum::-moz-meter-bar { background: antiquewhite; } .ph_meter:-moz-meter-sub-sub-optimum::-moz-meter-bar { background: steelblue; }

Here is the complete html code and the final result of the pH gauge.

<meter class="ph_meter" low="7" high="7" optimum="2" max="14" value="6"></meter> <meter class="ph_meter" low="7" high="7" optimum="2" max="14" value="7"></meter> <meter class="ph_meter" low="7" high="7" optimum="2" max="14" value="8"></meter> References

9 Javascript Libraries To Build Interactive Charts - ma, 20/04/2015 - 17:01

So you have in your hand tons of data, with a number of variables, that you have to somehow relay to somebody else. Raw, unorganized data is going to be difficult for them to understand. This is why you need help from charts. In web design, charts are one of the best tools for data visualization. It is easy to read, easy on the eyes and relatively easy to set up.

But let’s take things up a notch: let’s add animation and interactivity to those charts, so that readers can not only learn something new from the chart, but also play with it. It is actually easier than it sounds, thanks to a number of JS libraries out there. Let’s check them out.

1. Chart JS

Chart.js is a no-dependency library to build charts in 6 different types: line charts, bar charts, radar charts, polar area charts, pie and donut charts. The library is also split according to chart type so your pages aren’t bogged down with what is not needed. It supports responsive design and you can easily change variables like color or animation to customize the chart interface.

2. Chartist JS

Chartist JS is great library to build responsive charts that make use of SVG. Besides its responsiveness, Chartist gives you flexibility by using clear separation of concerns: style with CSS and control with JS. To make customization easier, the SASS files are included. The great thing here is you have limitless options to animate your chart using the Chartist animation API, SMIL, which gives you additional animation options.

3. C3 JS

C3 JS is a library to build charts based on D3 JS. It wraps up the required code to build charts with D3 JS, so you can skip writing the D3 code, and just input your data. C3 comes with a variety of API that you can use to control your charts easily. To customize your chart, define your own custom styles to the given CSS classes. Build charts from simple line charts to gauge charts. Check out this page to see how the library works.

4. Flot

Flot is a jQuery plguin for creating charts with interactive elements like turning a series on or off, data point interactions, panning, zooming and more. Flot comes with a variety of chart type options and if you want more ability on your chart, here are some plugins you can use as well. The charts will work well with browsers that support HTML canvases.

5. EChart

Echart is an amazingly comprehensive library from China which supports multiple chart types, can process big data (plotting up to 200,000 data points on a Cartesian chart), has scale roaming, the ability to effortlessly extract, integrate, and exchange data among multiple charts, allowing one to easily switch from one data type to another, and a whole lot more.

6. Peity

Peity will add a mini chart to your web page. It is a small jQuery plugin that transforms an element into a mini svg line, bar, donut, or pie chart. You just need to create an element and give a value like 1/5 and make a call peity('pie') on that element to make a mini pie chart. For instance, to create a donut chart that is only one-fifth highlighted, here is the HTML:

<span class="donut">1/5</span>

You can customize the chart color, radius, width and height, but by default it’s displayed in small size.

7. DC JS

DC JS has similarities with C3 JS in terms of engine used; they both use the D3 library to render charts in SVG. DC JS is created to help you visualize data and analysis for browsers and for mobile devices. Since it leverages on the D3 JS, it allows you to add user interaction to your chart. DC JS is one powerful library to create charts from simple to high complexities.

8. Google Chart

You can create interactive charts and data tools using the Google Visualization API via Google Chart. There are chart galleries to check out Google Chart’s data visualization capabilities. To start, embed simple JavaScript to your web page to load the Google Chart libraries you need. Then list the data you want charted, and make some customizations through the chart options. Finally create a chart object with an id, and on your web page, create a <div> with that id to display your chart.

9. NVD3

NVD3 is a set of reusable charts and chart components that are built with D3 JS. This library is hence a ‘template’ that will help make it easier for you to build charts. Check out the many sample charts built with NVD3 here.

HipChat Keeps Your Team Connected Across Multiple Platforms - ma, 20/04/2015 - 15:01

Editor’s note: This article is brought to you by HipChat.

Communication can be a problem when it comes working online and remotely. Requirements, reminders and reiterations can get lost when a message gets passed from one team member to the next. There are also so many things that could impede the workflow or work process of your team, things like working in different time zones, or even working on different operating systems.

If this is you, then you might want to try out HipChat. HipChat is a group chat service that caters to most, if not all, of the major desktop and mobile platforms out there. It is also available as a web app, and provides written, audio and video conferencing tools to help you get your message across to your team members.

Getting Started With HipChat

To register, HipChat needs your name, work email and password. You can start inviting team members at this point or leave it for later. Check your email for a nudge by HipChat to confirm your email address. Once you activate your account, you will end up here.

You can download the native HipChat app for your Mac, Linux or Windows, or get it on mobile for Android (4.0 and above) and iOS (iOS7 and above), or if you aren’t at your own computer, launch the web app instead to begin chatting.

Note: This review will center around the web app.

Getting Around In HipChat

Once inside the web app, you will be at the Lobby, where you can find all the Rooms that were created and People who are on HipChat. Toggle betwen the two groups to get a more filtered list; or if the place is too crowded, the filter search bar can help narrow down your destinations.

Once you click into any of the rooms or any of your team member’s name, the item(s) will be added to the left sidebar. This makes it easy to jump from one chatroom to the next.


The availability status of each team member helps give you an idea of when is a good time to approach them. There are three statuses available: Available, Away and Do Not Disturb, depicted in the customary green, yellow and red signal colors. To change your own status, you can do so at the top right hand side of the interface, or use the commands: /away, /dnd, or /back (for Available).

New Chat

Click on any of the available Rooms to start chatting with your team members, or click on a team member’s Name to go into 1-on-1 chat mode. At any time you want to start a new room, click New Chat. Give it a name, and a topic and choose the privacy access (Open or Private) for the room.

Room Features

In the conversation threads (rooms), you can use emoticons, share files of up to 50 MB per file, links and even gifs (check the Integration section). With the native apps, you can also find support for video calls, audio calls and screensharing (only during the trial period).

In 1-on-1 chat mode, all shared files and recently shared links, on the right sidebar. In rooms with a larger pool of participants, you will find an additional list of participants for the chatroom, along with options to rename your room, topic and toggle access settings on the right sidebar. Here’s also where you can find the Integrations feature.


One thing HipChat does that takes it up a notch compared to other group chat services is that you can extend its capabilities via add-ons. HipChat comes with 59 add-ons you can get including Asana, GitHub and Hip Gif (to add gifs with the /gif command). These integrations feed notifications from those services into HipChat. Now, you no longer have to pick a tool for all your team mates to migrate to – you can have them all.

Pricing Plans And Features

During the 30-day trial period, you will have access to all the features. The moment the trial period is up, you lose access to screensharing, audio and video calls, and searches on unlimited chat history (which will be capped at 25,000 messages for the basic plan).

The file storage capacity is also now capped at 5 GB unless you opt for its premium plan, HipChat Plus. Rates are at $2/user/month, and you can cancel at any time and will only need to pay for the last billing period. HipChat can also be deployed to your own server on special pricing rates (check out this link for discounts for academic organizations).


During the testing period, I had a couple of connection problems.

  • With the web app, I kept getting disconnected and had to reload the page to get connected.
  • With the audio call feature, after I hung up, the call was not immediately disconnected on the receiver’s side. The receiver had to manually disconnect the call.

Nonetheless, the support HipChat provides looks solid, if its help center is to be taken at face value. The Help center even has a Suggestion and Ideas section which the team acknowledges and actively responds to.

Final Word

HipChat is a fun, simple, cleancut app to use and its wide range of support on popular desktop and mobile platforms make it a great addition to any organization, including those that operate remotely. The use of @mention, and the plentiful notifications via email, in-app, desktop and even via sms, does its part in trying to keep remote teams continuously updated and connected.

15 jQuery Plugins To Make Smart Sticky Elements - vr, 17/04/2015 - 17:01

It is now common to see certain elements in a site fixed to a position when you scroll up or down the site e.g. the navigation menu, the header or the sidebar. This allows for the element to be readily available regardless of the user’s position.

Called a sticky element, this can be achieved just by using CSS, however, using this method, the effect is not reliable across multiple browsers. That is why we’ve put together a handful of JS libraries and jQuery plugins that will allow you to achieve this particular UX design with little to no hassle.

1. Waypoints

Waypoints is a library to execute a function based on the element position in the viewport. It comes with an shortcut function that makes that element “sticky”. You can customize the scrolling direction — up, down, and even right and left — as to which the element should stick within the viewport.

  • Dependency: None / jQuery (optional)
  • License: MIT license
2. Sticky Kit

With StickyKit, not only can you make an element stick within the viewport, but you can also make them stick within the parent element you designate to multiple elements at once. The plugin also comes with some advanced settings including custom Events and Triggers.

  • Dependency: jQuery
  • License: WTFPL
3. StickyJS

StickyJS is an easy-to-use jQuery sticky plugin that does what it says. The plugin works out of the box. Yet, if you need some customization, it comes with Options/Settings, Custom Methods and Events.

  • Dependency: jQuery
  • License: MIT license
4. HeadRoom

A sticky site header will take up valuable vertical space that makes a difference when you view the site on mobile. Headroom is a JavaScript library that will make your sticky header smart; the header will be hidden when users scroll down the page and show up upon scrolling up.

  • Dependency: None / jQuery (optional) / Angular (optional)
  • License: MIT license
5. MakefixedJS

Makefixed lets you make elements be fixed dynamically as users scroll the page. Just call the makeFixed() function on the element you want fixed. Check the demo to see it on action.

  • Dependency: jQuery
  • License: GPL
6. MidnightJS

Midnight allows you to stick multiple headers / elements and switch between them based on their position within the document (DOM tree), check out the demo to see what I mean. In addition you can change their color on the fly simply by adding the data-midnight attribute with the specified color name.

  • Dependency: jQuery
  • License: MIT license
7. ScrollMagic

ScrollMagic has advanced features to add interaction, during a page scroll. You can pin elements from specific scroll positions, add animation based on scroll position, or even make an awesome parallax effect. The demo gives you some insights of what this plugin can do.

  • Dependency: jQuery / Velocity.js
  • License: Dual License (MIT and GPL)
8. onScreen

onScreen is similar to Waypoints — it allows you to execute functions as the element is entering, leaving, or reaching certain positions within the browser viewport.

  • Dependency: jQuery
  • License: MIT license
9. jQuery Pin

jQuery Pin is a small jQuery plugin to “pin” or “unpin” elements to a position, when you scroll the page. My most favorite part of this plugin is the option to disable it at certain viewport widths.

10. Sticky Float

Sticky Float allows us to give elements a fixed position that is relative to its parent. You can set the sticky option according to your needs with the provided parameters and by changing the value. Catch the demo here.

  • Dependency: jQuery
  • License: Undefined
11. Zebra Pin

Zebra Pin is a lightweight plugin to make any element pin to their container. With this plugin you can add "sticky-ness" to elements in your project like to your navigation, sidebars, headers and footers, or other elements that you want to keep visible when users scroll down. Check out the demo.

  • Dependency: jQuery
  • License: GPL license
12. HC-Sticky

With HC-Sticky, you can make sticky elements that refer to its container, to any given element, or to the document itself. This plugin has some options that you can adjust to your need, like distance from the top and bottom to start floating, and other options.

  • Dependency: jQuery
  • License: MIT license
13. Sticky Mojo

Sticky Mojo is a lightweight, fast, and flexible jQuery plugin to make awesome sticky elements. It’s compatible with modern browsers and will degrade gracefully in IE.

  • Dependency: jQuery
  • License: MIT license
14. Sticky Navbar

If you want make single page navigation which sticks when one scrolls down, this library is for you.Sticky Navbar will put the navigation at the top of the browser window and highlight the anchor link to connect to the corresponding section on your page. You can also add Animate.css to beautify the navigation effect.

  • Dependency: jQuery
  • License: MIT license
15. StickyStack

StickyStack will make elements stack with another when users scroll the element and reach the top of the viewport. With this library, your long page will transform into stacked cards.

  • Dependency: jQuery
  • License: Undefined

Top 15 QuickStarts for OpenShift - vr, 17/04/2015 - 15:01

We previously wrote about the apps you can use to get started on OpenShift, the cloud platform service that offers free quota usage. Today we are going to look at QuickStarts instead.

QuickStarts, as the name suggests, allow you to "start quick" with OpenShift by auto-combining an app’s source and its requirements to easily launch new apps. It is an add-on that makes it easy for someone to get started with an application or framework on OpenShift. Put simply, it allows you to enjoy a custom-hosted service, let’s say a blog or cloud storage, for free without going through installation hassles.

In developer speak, a QuickStart is simply a Git source code repository that’s paired with one or more cartridges. In layman’s terms, a QuickStart extends the Red Hat’s cloud platform by bringing some technology (application or framework or app stack) to OpenShift. Here are 15 QuickStarts that you should probably check out on OpenShift. If you have more to add to the list, share with us in the comments.

How To Create A Static Blog Using Cactus [OS X] - do, 16/04/2015 - 17:01

If you do not require a CMS and would prefer just getting a static site or blog, then Jekyll is a good tool to take a chance with. However, if you prefer a tool with a GUI, rather than working with command line tools, then you might want to check out Cactus.

Cactus is a free static site generator equipped with powerful tools that can help you build websites locally, faster and easier with modern web technologies. It gives you a starting point in your project with 4 predesigned templates so you can hit the ground running.

While working on your project, Cactus will monitor every change you make on your project and automatically refresh the browser so you can see the changes immediately, on your Mac or mobile device. It also supports SASS/SCSS and Coffescript out of the box, so every change on this file is also automatically generated.

Get Started

First of all, you need to download Cactus from its homepage, then run the installation. Once complete, open it, you will see four buttons: Create, Deploy, Edit, and Preview button.

To create a new project, click Create. You will see 4 templates available there. For this tutorial, we are going with the Blog template. Click Create.

You will be asked to give name of your project and choose the location where the project exist. Here i give name “My Awesome Blog” for the project. After that, you will see your project already in Cactus.

Modifying Files

The generated project using Blog template now exists on your Finder. We will now inspect the elements required to build our Blog. Head over to the directory where your files are kept. The main directories that we will use are Templates, Pages, and Static directory. Let’s skip the others for now.

To keep things brief, here’s what each directory is for:

  • Templates: Contains HTML files which behave as template, used by HTML files on pages to build on.
  • Pages: Contains all HTML files that will become a page with the same path. eg: hello.html here will become
  • Static: Contains all static resources like CSS, Javascript and images.

Now, we will edit three main files from the directories: base.html and post.html in the Templates directory and index.html in the Pages directory.

Cactus uses Django Template Engine for the templating language. With this, you can include HTML elements from other HTML files, so you don’t need to duplicate codes. The features that are most used here are template inheritance and variable.

To see how they work, first open the base.html on Template directory.

<!DOCTYPE html> <html lang="en"> <head> &#x9;<meta charset="utf-8"> &#x9;<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> &#x9;<meta name="viewport" content="width=device-width, initial-scale=1"> &#x9;<title>{% block title %}Blog{% endblock %}</title> &#x9;<link rel="shortcut icon" href="{% static '/' %}">&#x9; &#x9;<link rel="stylesheet" href="{% static '/css/style.css' %}"> &#x9;<link rel="alternate" type="application/rss+xml" title="My Blog Feed" href="/rss.xml"> </head> <body> &#x9;{% block content %} &#x9;&#x9;Main content &#x9;{% endblock content %} &#x9;--- </body> </html>

base.html is the simple html file that we use as a ‘skeleton’ template. It contains common elements of our site. You can see some “blocks” in there; we will use the child template to override these blocks.

Now open the post.html located in the same directory with base.html.

{% extends "base.html" %} {% block title %}{{ title }} | Cactus{% endblock title %} {% block content %} &#x9;--- &#x9;<header> &#x9;&#x9;<h1>{{ title }}</h1> &#x9;&#x9;<h2 class="headline">{{ headline }} </h2> &#x9;</header> &#x9;<section id="post-body"> &#x9;&#x9;{% block body %} &#x9;&#x9;&#x9;This is where the post contents is. &#x9;&#x9;{% endblock body %} &#x9;</section> &#x9;--- {% endblock content %}

The post.html contains the markup for our blog entry page. At the first line you can see that post.html extends the base.html. This means we will override the blocks on base.html with the blocks here.

We can also find variables here, such as {{ title }} and {{ headline }}. We will define the values of these variables in the blog entries post later.

Now, lets look at the {% block body %} block. This will be overridden by the child template that contains the post entries of our blog.

Go to the directory pages/posts. Here are the rest of our post entries.

title: My Post Entries headline: My Post Headline author: Agus date: 15-01-2015 {% extends "post.html" %} {% block body %} {% filter markdown %} Lorem ipsum dolor sit amet, consectetur adipisicing elit. Earum, perferendis inventore dolorem rerum et tempora sint nemo illum ab saepe, assumenda, amet illo deleniti officiis, voluptatem maxime atque vero sunt. --- {% endfilter %} {% endblock body %}

In the post entries, we give value to the variable, like title, headline, author, and date. This value will pass when we call the variable name on the parent template. Then we write the content of our blog with Markdown.

Now we will go to the index page of our blog, open index.html in the pages directory. It contains the list of our blog entries and the link to the each entry. The main code looks like below:

{% extends "base.html" %} {% block content %} &#x9;-- &#x9;<ul id="post-list"> &#x9;&#x9;{% for post in posts %} &#x9;&#x9;&#x9;<li> &#x9;&#x9;&#x9;&#x9;<a href='/{{ post.path }}'><aside class="dates">{{|date:"M j" }}</aside></a> &#x9;&#x9;&#x9;&#x9;<a href='/{{ post.path }}'>{{ post.title }} <h2>{{ post.headline }}</h2></a> &#x9;&#x9;&#x9;</li> &#x9;&#x9;{% endfor %} &#x9;</ul> &#x9;-- {% endblock content %}

At this point we have a simple blog with two main pages, the index page that contains the blog entries, and the blog entry page itself.

Go to Cactus window, and click preview button to start the server. It will automatically open the browser and open your website.

Styling the Blog using SCSS

A great feature of Cactus is that it works with SASS/SCSS out of the box. Just drop your .sass or .scss files into the static directory and every time you edit and save the files, Cactus will automatically generate the CSS.

Here I will give an example using bootstrap-sass to styling our blog. Assuming you are using bower, open terminal, and navigate to the static directory of our project using cd command. Then install bootstrap-sass using this command:

$ bower install bootstrap-sass-official

Once the download is complete, you will see a bower_components directory inside the static directory containing bootstrap-sass-official.

Now go to this directory: static/css. Create the scss file, give it the name syle-bs.scss and insert this code.

@import "../bower_components/bootstrap-sass-official/assets/stylesheets/_bootstrap";

What the code does is it import everything from bootstrap-sass. Once you save style-bs.scss, you will see style-bs.css generated on the same directory that contains all styles from bootstrap.

Deploy your Project

Lastly, when your project is ready, you can deploy your project to the live version easily using Amazon S3, just follow these steps to make it all work properly.

10 Unique Playing Card Designs You&#8217;d Rather Keep than Play - wo, 15/04/2015 - 17:01

According to Wikipedia playing cards gave been around for over 1,100 years now. They have changed considerably since then. Different variations of decks have been created, yet what we recognize as a “regular deck of cards” hasn’t changed much for a while. At least that’s what you might think! There are quite a few companies that have created special decks which range from odd to beautiful to useful.

If you collect cards (or want to start) or are just looking for one perfect deck, perhaps you’ll find what you need in this list.

1. Contraband

This is an exquisitely designed deck with a distinct personality. It really looks like something you expect to find in a sinking pirate ship – the term booty definitely seems to apply.

The deck costs $7.95, a very modest sum. You can also grab the moody book lamp that goes along with it for $149.95. This seems a bit steep but each book lamp is hand-crafted and contains a secret stash that fits two Contraband decks.

The design of the website is also something to behold, it makes the deck look so much better – seeing it in a fitting environment. Grab Contraband now, it’s a work of art, not just a set of cards. [Get them here]

10. Prohibition

I drink next to no alcohol but I really love how well made and unique the Prohibition set is, which consists of six decks, all a nod to different alcoholic drinks. Absinthe, Disparos Tequila, Rebellion Rum, Moonshine, White Wolf and 52Proof Whiskey make up the set in a beautiful slim box.

Each deck has a beautiful and unique design. It’s hard to decide on a favorite.

You can grab the lot for $125 at which isn’t a bad deal considering you are getting 6 decks and a beautiful wood box! [Get it here]

3. Mystery Box

If you’ve seen the Mystery Box Ted Talk from J.J. Abrams you know what this deck is all about. Mr. Abrams loves secrets and his company, Bad Robot, wanted to instill this in a pack of cards. The cards themselves look great and at $9.95 a piece they are a steal.

What I really love through is The Lockbox you can grab for $149.95. This is a bit pricey but you’ve got to love the 100 year old reclaimed wood, iron hardware, letterpress note, wax seal – all the works!

$1 per deck is donated to 826 National, a non-profit dedicated to promoting creative writing in schools and workshops around the USA, giving you another reason to grab this great looking deck. [Get them here]

4. Deck Out: Fashion Playing Cards

To tell you the truth, I’m the last person you would call a fashion guru, but that doesn’t stop me from appreciating this wonderful deck by Connie Lim. The Fashion Playing Cards Deck is the accumulation of her card designs which she made one-by-one as far as I am aware.

Grab the set for $54.99 from the Connie Lim Webshop. If you like the designs take a look at her prints, you can grab all the cards there as well! [Get them here]

5. Charity: Water

This deck is less flashy than the ones we’ve seen so far but 100% of all proceeds from purchases go toward a great cause: bringing clean and safe drinking water to people in developing nations. If you’re a collector and you spend hundreds of dollars on cards, why not spend an extra $5 per deck and contribute to this effort?

While not as flashy, I do love the minimalism and the clarity of the water tank logo throughout the design. Buy a deck now and help people to better drinking water! [Get them here]

6. Bruce Lee Playing Cards

When I started writing up this article I didn’t think Bruce Lee would come up! I had a look at this deck out of pure fascination and it turned out to be pretty good. The cards come in the same colors as the legend’s famous yellow jumpsuit, which can be a little bit off-putting, you know, for card playing. That said, I like the overall design and feel of this deck, especially the way quotes are positioned like a black belt – the perfect homage.

This deck will set you back $14.95. [Get it here]

7. AVES Playing Cards – LUX Edition

A striking combination a fine art and birds, this is a beautifully designed deck by Russian artist Karina Eibatova. The back looks a bit trippy when fanned out but I love birds and I think the aces are one of the best designed ones I’ve seen so far, especially for clubs. You can grab a deck on Lux Playing Cards for $12. [Get it here]

8. MailChimp

Want to geek out by buying playing cards that are made in collaboration with a web app? If geek is your thing the MailChimp playing cards are a great choice. I expected them to be a marketing gimmick with MailChimp’s logo all over the place but I was pleasantly surprised. The only actual logo I found was on the gold closing tape which looks fantastic by the way.

You can get a black or a red pack for $9.95 each, or you can get a 12-pack brick for $125. I’m not sure I’d want a 12-pack of Mailchimp cards but a black one is welcome in my collection.

Buy them and you’ll also be supporting the Fugees Academy which is a member of the Fugees Family – a non-profit dedicated to working with child survivors of war. [Get them here] 9. The Design Deck

I’m a big fan of design (since I can’t really do it myself) so this deck strikes a chord with me. You get to play cards and learn about typefaces, fonts, art-deco and other design concepts. Each of the 52 cards teaches you something great. It’s a shame they don’t have a second color deck with more. Perhaps this should be the way to teach design! You can buy a deck from Art Of Play for $20. [Get them here]

10. Dan And Dave Variety Box (Winter Ed.)

Dan And Dave offer a number of playing cards, one of my favorites is the variety box, specifically the Winter Edition which draws inspiration from the fall/winter colors of Yosemite. For $149.95 you get 12 decks which means you get them for $12.50 each, plus the awesome looking box of course. [Get them here]

Bonus: 5 More Card Designs

Here are more playing card designs that deserve a mention.


You didn’t really think there would be any bacon involved right? I don’t even want to go into it. Why buy this for $12 from Art Of Play? Because bacon. Convinced? [Get it here]

The Goonies

Do you love the movie The Goonies? This is your lucky day because some smart person on Kickstarter thought this was the World wanted and it seems the World has proved him right. The deck is available from Albino Dragon for $14.99. I’m not saying I’ll go right ahead and buy one but the art is impeccable, well worth the $15 if you’re a fan! [Get it here]

A Deck Of Playing Cards By Pedale Design

Another successful Kickstarter project (funded to 2300%), this deck is for those who like pixel perfect design. They have a couple of decks one black, the other red, on their Misc Goods Co website going for $15 a piece. [Get them here]

Distant Early Warning Card Deck

Designed by Eric McLuhan, award-winning media and communications expert (and son of media theorist and academic, Marshall McLuhan), the deck is available for CAD65 on Eric McLuhan’s products page. You can take a look at the full deck here. [Get them here]

IMAGE: McLuhan Galaxy Glitch

Glitch started its life on Kickstarter and was successfully founded. It’s a unique set which basically adds glitches to classically designed cards. The concept is awesome although it may be a bit annoying to play with if you have OCD. Find it on Amazon for around $14. [Get them here]

7 SEO Tip to Give Your Local Business a Boost - di, 14/04/2015 - 15:01

Search Engine Optimization is an intricate, methodical and important element of any online business, or any corporate entity for that matter. Without SEO, your website will just be buried below the rotting pile of search engine results and you’ll get almost zero conversions. With the help of a few local SEO tips though, your unfortunate situation can turn around.

As a business, you know that the opinion of your customers or clients about you matters. Not only can you forge trust between one another, but you also can open doors to future clients to like you.

When users google local services, they will see a map of the nearest outlets to get the services they searched for. These results are often separated from Google’s main organic results.

So if your company has received good reviews, even if your website’s not yet optimized for search engines, you will yield top results, and often, positive conversions. Let’s look at a few tips that will help you boost your business’s online presence locally.

1. Get Winning Reviews

So you want a good cup of coffee but since you’re new to the city, you don’t know any coffee shops close to you. Naturally, you google for coffee shops around your location. If there are a lot nearby, how do you choose? It will be impossible to try all coffee shops to decide which you will like most.

The better alternative will of course be to read what other people think of the coffee shops in your area, and pick the ones who got the most positive feedback.

As a business owner, what does this mean to you?

Well, the opinion of your clients are important for you, especially if they are positive. Reviews on sites such as play a major role in local SEO and establishing trust in potential customers. How do you get these reviews? By asking your customers to leave a review if they liked your service or product. The more, the better. Remember that anyone can leave a review; it doesn’t have to be a customer.

You should also know that whenever Google finds a website that mentions your business name and your address, it counts as an "upvote" or a backlink to you. This will help you because it increases your trust rating from Google.


Microsoft’s search engine Bing is also one factor to consider. Currently, Bing offers services for places of business (which is similar to Google Maps/Places). Using this service you can:

  • Add a local business. Bing allows small and local businesses to be listed on their maps. If you are a small store, this is recommended for you.
  • Add businesses with multiple locations. This category is effective for smaller chains like franchises. Being able to connect your branches through the Bing Places will help your customers from different parts of the locality to connect to you, and, if you’re lucky, you might even get valuable conversions. You can add up to 10,000 locations using this option.
  • Put businesses without a physical store on the map. This option is perfect for businesses that take the service to where their customers are e.g. plumbers, home-tutors, and other home-services.

Yahoo also allows you to list your business in more than 50 directories. You can include offers and extra details to encourage clickthrough. It charges $30 a month to be listed.

2. Start your own Blog

If you want to dominate the local market offline and online, you need to offer up a lot of information, like a local phone number, local address, email address, and maybe live chat if really needed. But the real magic happens when you have a blog for your business.

Having a blog helps you to target the right keywords as it establishes trust on your website. Use blog posts to establish trust from search engines and people. You can do this by creating blog posts targeted towards your relevant keywords even if their monthly search volumes are not high. You can also do simple techniques like including the city name to your domain (or subdomain).

This makes your website more identifiable with the local audience and will make it easier for you to get local reviews. This way, you can reach a small number or relevant audience with less competition. And over time, you’ll find out that these pages rank well.

One more thing that you need to remember about starting your own blog is not to be selfish — you should also blog about your niche in general. You can write several articles about yourself but you can also review your competitors, be fair in evaluating. And never, ever bash them. Average Internet users are now intelligent enough to notice that your blog is talking about no one else but you. And that shouldn’t be the case.

3. Use the Right Keywords

If you scour the Internet for SEO tips, they will always mention that keywords are what makes your website rank where they are supposed to be. You have to pick the right keywords to rank for because no matter what you do, if you don’t have any reference for the searcher to find you, you will not be found.

If your target audience is within Los Angeles, it is only intuitive to add “Los Angeles” in your keyphrase. For example, if you are selling perfume in Los Angeles, then you should aggressively blog about your niche in an organic manner. However, despite your wanting to target keywords easily, you shouldn’t start writing articles that are poor in quality.

Common bad practices include:

  • Keyword stuffing
  • Article Spinning
  • Plagiarism
  • Using keywords for unrelated articles

These practices don’t benefit your rankings but actually jeopardizes them. If you publish content that is irrelevant or unoriginal, chances are, you will lose the trust of your audience and you get down-voted on search engines.

However, the best thing to do about this is to write without thinking of search engines. Your keywords should be fluidly inserted into the articles so that when the user reads it, it still makes sense.

  • Put the keyword on the meta tags of your code (if you’re running on WordPress, then the Yoast plugin will make your job easier).
  • Make sure that your keyword appears at least once in the title (h1 or h2 tags), in the body and in your images’ alt tags. Remember not to stuff your keywords. It worked in previous search engine algorithms but not in modern ones.
  • Remember that you should have at least 300 words for your pages to be ranked.
4. Create Locally-Specific Pages

Having a target location matters in search engine results. While you would want to boost your presence for the world to see you, your efforts (and efficiency) will have value if you target where your target business is.

If you are a used car dealer business located in New York City, you would want New Yorkers to find you more than anyone else in the world. If you want your customers to find you, you have to drill down your targeted location to a specific place.

This method is also advisable because you are able to limit your competition in the rankings. If you become successful in your SEO efforts, you will reach the upper results without spending too much time or effort.

Take our used car dealer example. If you will search for "Used Cars", you will probably get some results that are more difficult to compete with:

In the above example, the top results for the keyword used cars have page ranks of 8. That means it will be harder for you to rank your keywords.

But if you use "Used cars in New York", you will be getting results for pages with PR4, a number that will be easier to compete with.

The rule of thumb on this is that your pages should have at least 400 words stating your business and how it pertains to your location. Also, follow the tips in point #3.

5. Get Backlinks from Local Blogs

One of the recurring tips you will find on how to promote a blog is by guest posting. But under the context of local SEO, simply guest posting will not cut it. Suppose you have a brick-and-mortar business in Los Angeles and you want to get your name out there, but your website isn’t receiving any traffic at all. What is the best way to kickstart everything? I’m glad we’re on the same page: ask local bloggers to write a story/review about your business or submit a guest post to them.

For example, if you have a tech-related business in Los Angeles that’s just weeks old, or relatively new to the online scene, the best way to find tech bloggers is to, well, Google them. Search engines are designed to behave the same way as how humans search for information. This means that Google, Bing or Yahoo will show on their first pages results that they think are trustworthy. These pages, most probably, contain the good content you are looking for.

And how do they determine trust? Do search engines know what trust is?

Well, yes and no. In reality, search engines are just a bunch of algorithms designed to behave like humans. So they need the opinions of humans to determine trustworthiness. This means that if a website is in the top result of your search query, it is probably the content most linked to. If you get a lot of websites link to you, you will be able to rank higher.

But not all links are made equal; some links are more valuable than others. This means that not all websites who link to you are good, and you can cheat search engines by creating bogus pages that link to your content. That doesn’t happen, at least not anymore.

To rank higher, you must be trusted by websites that are trustworthy themselves. A backlink from a PR1 website is way different than the ones given by a PR8. The latter will probably be, in a wider sense, useless because search engines don’t trust them yet.

But how do you get links from higher PR websites? Publish interesting and sharable content and make your local connections link to you

6. Join Local Social Media Groups

This is an intuitive but highly underrated technique. Social media presence and engagement affects SEO and people’s trust. For example, let’s say you are a pet grooming company based in Tokyo. What do you think would be the best way to reach pet lovers in Tokyo? The answer is pretty simple: you start looking for groups on Facebook dedicated to pet lovers located in Tokyo.

If you live in a city, chances are high that there are dedicated Facebook and Twitter groups for your city. Think of this, as of 2014, there are over 1.35 billion Facebook users all over the world. It’s impossible to not be able to find a group for your niche.

It makes sense to join local social media groups because they are closer to you and could possibly give you conversions. This way, you can also start building your community, which could lead to returning customers.Here’s what you can do:

  • Join their community, ask insightful questions, provide useful answers, and give valuable resources.
  • Interact with members regularly, as much as possible, comment on their concerns and questions.
  • Regularly share your articles on their pages (just take note of the rules, because some pages don’t allow link sharing in their groups)
  • Try and share other articles from related niches too (so that you won’t be seen as someone who is just concerned about promoting your own service).
7. Slither Your Way Into Credible News Websites

Now that you have connected to trusted bloggers and local social media groups, it’s time to connect with credible news websites.

If you can have a local media cover your business, you ultimately enjoy long-term and positive results on your search results and conversions. Once you get coverage from trusted and reliable media companies, you will be able to invite more business to your company.

But what’s the difference between blogs and news agencies?

Bloggers are usually made up of individual to a small group of people providing relevant information about a certain niche. They commonly talk about guides, experience-based articles and lists. On the other hand, news websites are commonly made up of a larger crowd, reporting about real-time events.

To put it simply: blogs can be informative, opinionated, or promotional while news websites deal mostly with announcements.

What you can do for your website is to start building relationships with the local media by encouraging them to try your products or services. In the media world, it is commonly known as X-Deals. For example, if you are a bakery, you can send your best bread to a local news reporter and email him to ask if he could review it for you.

You can also send emails to reporters about an event you will be hosting (that will, of course be with charitable aims) and ask them to cover it for you. This will serve as an advertisement for your company. Some companies do this often because they know that most people trust the news, and if they are reported in there, chances are, the audience will see them as someone trustworthy as well.


Optimizing a website is difficult. You’ll have to use up a lot of time, effort, money and, most importantly, patience to make your page go number one. If your pages don’t appear in the first page after a day, don’t fret. It’s part of a process. Just keep going. Good luck!

Basic SEO Tips For Images You Should Know

What You Don&#8217;t Know About Calculating Percentage Margins in CSS - ma, 13/04/2015 - 15:01

Most web designers think they know CSS pretty well. After all, there isn’t that much to it — a few selector types, a few dozen properties, and some cascading rules that you barely need to remember since they boil down to common sense. But when you get down to the nitty-gritty level, there are plenty of obscure details that few designers truly understand.

When I examined the results of a free CSS test I’ve offered online for the past six months, I discovered one question that almost no one got right. Of the thousands of people who took the test, fewer than 14% got it right.

The question boils down to this: How Do You Calculate Percentage Margins?

The Question

Say your site has a container div, and inside that, a content div:

Now, let’s give that content div a top margin:

.content { margin-top: 10%; }

Okay, so it’s 10% … but 10% of what? That’s the question that only 13.8% of people can answer correctly. And keep in mind: these people have access to Google!

What I love about this question is that it seems like the answer should be obvious. So much so, that I suspect most people just take a guess (and guess wrong). But maybe it doesn’t seem obvious to you. I mean, if you really use your imagination, there are many ways the browser could conceivably calculate a margin like this.

So how about if I narrow it down for you since the question in the test is actually multiple choice. Here are your options:

  • 10% of the content div’s height
  • 10% of the container div’s height
  • 10% of the content div’s width
  • 10% of the container div’s width

Remember, only 13.8% of people can pick the right answer from this list. That’s way worse than chance!

Look closely at the answers; you’ll see there are really only two things you need to know:

Container or Content?

First, is the size of the margin based on the size of the content div itself, or on the size of the container div?

Now this isn’t a gimme, but you can probably trust your instincts. If I set a div to be 50% of the width of its container, and then I want its left and right margins to fill the rest of the space, I’d naturally set them to 25% each (so the percentages add up to 100%). For that to work, percentage margins must be based on the dimensions of the container.

Sure enough, two thirds of people who take the test get this part of the answer right.

Width or Height?

Second, is margin-top’s size based on the width or the height of that element?

If you’ve been paying attention, you’re probably on your guard already. For so few people to pick the right answer, this has got to be a trick question, right?

And yet, I bet you can barely believe that the answer isn’t height. Well, it isn’t.

Yes, we’re talking about a top margin here. Yes, the size of that margin is a vertical measurement. Yes, if a block is 50% of the height of its container, and you gave it a top margin of 25%, you’d expect that to be 25% of the height of the container. And you’d be wrong.

Don’t feel bad if you thought it had to be height. Nearly 80% of people who take the test agree with you:

It Makes Sense… No, Really!

Still don’t believe it? Here’s a quote from the W3C CSS spec:

The percentage is calculated with respect to the width of the generated box’s containing block. Note that this is true for margin-top and margin-bottom as well.

The same goes for top and bottom padding, in case you were wondering. As for borders, it’s illegal to specify their width as a percentage.

So at this point, you’re probably thinking the creators of CSS are either bonkers, or they just made a really dumb mistake. But I’m here to tell you, there are two good reasons to base vertical margins on the width of the containing block:

Horizontal and Vertical Consistency

There is, of course, a shorthand property that lets you specify the margin for all four sides of a block:

margin: 10%;

This expands to:

margin-top: 10%; margin-right: 10%; margin-bottom: 10%; margin-left: 10%;

Now, if you wrote either of the above, you’d probably expect the margins on all four sides of the block to be of equal size, wouldn’t you? But if margin-left and margin-right were based on the width of the container, and margin-top and margin-bottom were based on its height, then they’d usually be different!

Avoiding Circular Dependency

CSS lays out content in blocks stacked vertically down the page, so the width of a block is usually dictated entirely by the width of its parent. In other words, you can calculate the width of a block without worrying about what’s inside that block.

The height of a block is a different matter. Usually, the height depends on the combined height of its contents. Change the height of the content, and you change the height of the block. See the problem?

To get the height of the content, you need to know the top and bottom margins that are applied to it. And if those margins depend on the height of the parent block, you’re in trouble, because you can’t calculate one without knowing the other!

Basing vertical margins on the width of the container breaks that circular dependency, and makes it possible to lay out the page.

Ace the Class

So there you have it: the hardest question on the test, and now you can answer it. Want to know how you’d do on the rest of the test? Try it yourself. I promise, most of the questions are much easier than this one.

Meanwhile, I’m in search of a new toughest question! What detail of CSS do you think nobody knows?
