Cloud-based Business ideas

Are you interested in starting a cloud based business? If yes, then below are the top ten cloud based business ideas you can start from home.

Wikipedia defines cloud computing as “internet-based computing whereby shared resources, software, and information are provided to computers and other devices on demand.”

Given the explanation above, popular platforms like Slideshare, Skype, Gmail, YouTube, Vimeo, Flickr, Amazon AWS and Cloudfront, Dropbox and WordPress can reasonably be included in a list of cloud applications; because they all hold your data (presentation slides, emails, videos, blog posts, etc), so you don’t have to worry about them.

Cloud computing provides a much more reliable alternative to keeping files on your own computer; a mode of storage that has been rendered insecure due to the emergence of various types of viruses and other threats to information security.

On the surface, cloud computing has many advantages over traditional methods of data storage. For example, if you store your data in a cloud-based retrieval system, you will be able to get back your data from any location that has internet access. And you wouldn’t need to carry around your physical storage device or use the same computer to save and retrieve your information. In fact, in the absence of security concerns, you could even allow other people to access the data, thereby turning a personal project into collaborative effort.

Like any other innovation that offers huge solutions for individuals and businesses, cloud computing has created huge opportunities for entrepreneurs who have a knack for computers and ICT. If you have a solid background in ICT and in-depth knowledge of cloud computing, then starting a cloud-based business might just be a life-changing business move for you.

Building a Website Scraper using Chrome and Node.js

A couple of months back, I did a proof of concept to build a scraper entirely in JavaScript, using webkit (Chrome) as a parser and front-end.

Having investigated seemingly expensive SaaS scraping software, I wanted to tease out what the challenges are, and open the door to some interesting projects. I have some background in data warehousing, and a little exposure to natural language processing, but in order to do any of those things I needed a source of data.

The dataset I built is 58,000 Flippa auctions, which have fairly well-structured pages with fielded data. I augmented the data by doing a crude form of entity extraction to see what business models or partners are most commonly mentioned in website auctions.

Architecture

I did the downloading with wget, which worked great for this. One of my concerns with the SaaS solution I demoed, is that if you made a mistake in parsing one field, you might have to pay to re-download some subset of the data.

One of my goals was to use a single programming language. In my solution, each downloaded file is opened in a Chrome tab, parsed, and then closed. I used Chrome because it is fast, but this should be easily portable to Firefox, as the activity within Chrome is a Greasemonkey script. Opening the Chrome tabs is done through Windows Scripting Host (WSH). The chrome extension connects to a Node.js server to retrieve the actual parsing code and save data back to a Postgres database. Having JavaScript on both client and server was fantastic for handling the back and forth communication. Despite the use of a simple programming language, the three scripts (WSH, Node.js, and Greasemonkey) have very different APIs and programming models, so it’s not as simple as I would like. Being accustomed to Apache, I was a little disappointed that I had to track down a script just to keep Node.js running.

Incidentally, WSH is using Internet Explorer (IE) to run its JavaScript; this worked well, unlike the typical web programming experience with IE. My first version of the script was a cygwin bash script, which involved too much resource utilization (i.e. threads) for cygwin to handle. Once I switched to WSH I had no further problems of that sort, which is not surprising considering its long-standing use in corporate environments.

Challenges

By this point, the reader may have noticed that my host environment is Windows, chosen primarily to get the best value from Steam. The virtualization environment is created on VirtualBox using Vagrant and Chef, which make creating virtual machines fairly easy. Unfortunately, it is also easy to destroy them. I kept the data on the main machine, backed up in git, to prevent wasting days of downloading. This turned out to be annoying because it required dealing with two operating systems (Ubuntu and Windows), which have different configuration settings for networking.

As the data volume increased, I found many new defects with this approach. Most were environmental issues, such as timeouts and settings for the maximum number of TCP connections (presumably these are low by default in Windows to slow the spread of bots).

Garbage collection also presented an issue, since the Chrome processes consume resources at an essentially fixed rate (their memory disappears when the process ends). The garbage collection in Node.js causes a sawtooth memory pattern. During this process many Chrome tabs open. The orchestration script must watch for this in order to slow down and allow Node.js to catch up. This script should also pause if the CPU overheats; unfortunately I have not been able to read CPU temperature. Although this capability is supposedly supported by Windows APIs, it is not supported either by Intel’s drivers or my chip.

Successes

A while back I read about Netflix’s Chaos Monkey and tried to apply its principle of assuming failure to my system. Ideally a parsing script should not stop in the middle of a several day run, so it is necessary to handle errors gracefully. Although the scripts have fail-retry logic, it unfortunately differs in each. Node.js restarts if it crashes because it is running tandem with Forever. The orchestration script doesn’t seem to crash, but supports resumption at any point, and watches the host machine to see if it should slow down. The third script, the Chrome extension, watches for failures from RPC calls, and does exponential backoff to retry.

Using the browser as a front-end gives you a free debugger and script interface, as well as a tool to generate xpath expressions.

Possibilities

The current script runs five to ten thousand entries before requiring attention. I intend to experiment with PhantomJS in order to improve performance, enable sharding, and support in-memory connections.

The Alternative To Content-Writing Services: Free Unique Articles For Your Web 2.0s

Content-writing services can be expensive especially when a large amount of articles is needed for SEO purposes, but there is an alternative. I love being honest and transparent about everything I do in Internet marketing. This applies to the relationships that I try to establish with my readers and customers, as well as to the SEO techniques I employ while trying to make it to the top of Google. For a new site such as mine, however, employing only White Hat techniques may never bring it to success. Getting links from established sites is not easy when your site has no traffic and no reputation. Some Gray Hat and a very few Black Hat techniques can come in handy.

One such technique is building supporting Web sites to serve as ‘link sources‘ for the money-making site. The idea is to build a low-to-medium-quality-content site, similar to the niche sites that used to dominate Google before the advent of Panda and Penguin. Poorer-quality links are used to support the site and spammy links to these links will give it more authority. Here is a diagram to show you how the strategy works.

Today, I am not going to go into the details of this tactic for backlink creation, but I want to focus on the tier-two sites, the low-to-medium-quality blogs that link directly to the money site. These sites can be normal Web sites lust like the money site itself. The host needs to be different from the one the money site is on, because Google does not count links connecting two sites using the same IP address. This is important. Some months ago, it made the difference between page one of Google and the Sandbox to me. Another option, is to use Web 2.0 properties such as WordPress (the commercial site), Blogger, Weebly or a billion others.

These sites allow their users to build blogs for free, although the options are limited and the content is moderated. Content is precisely the subject of this article. In the post-Panda and post-Penguin age, building one-paged Web sites as tier-two link sources no longer works. A blog that is constantly updated and filled with many, original articles is required to achieve the goal at hand. I go for two new articles per month. That is not a lot for one site, but when you consider that twenty or thirty sites on tier two, it can become a bit scary.

What the heck, Arthur?! How are we supposed to do that? Two new articles every month for thirty sites is sixty articles a month. You need to employ dozens of content-writing-service companies and pay hundreds or thousands of dollars to get that job done. You’re a fool as usual…

Mr. Huggins would be correct, if not for the fact that I have found a pretty sweet trick to get decent, readable, lengthy and unique articles, which can be prepared for publication in ten minutes each. That is six articles per hour. Since you, I hope, are not visually impaired as I am, you should take no more than 3-5 minutes to have each article done. Even assuming six articles per hour, this means that in four hours you can have a year worth of articles ready for one site. So how do I do it? There are various ways to get cheap, free, unique articles without having to pay expensive content-writing services to have them written out for you.

spinnerchief 1. Spun Articles—Write one article, use software such as Spinnerchief and create multiple copies of the article that will be worded slightly differently to pass copyscrape tests. The problem with this method is that the topic of the article and the sense will be the same, no matter how clever your spinning technique is. A Web site with twenty-four articles all containing the same information is not a low-to-medium-quality site; it is a spam-quality site. Most Web 2.0 sites will detect it as spam and delete it before Google can even send it to the sandbox. This is not an option here.

2. Article Directories—Sites such as Ezine Articles or Go Articles allow publishers to copy their content provided that the author is credited and links in the article are not modified. This method does not work either, because unique articles are needed for the tier-two sites to rank in Google. Since the articles have already been published on another site, namely the article directory itself, they will not be considered to be unique. This is another option better not be considered.

3. The Encoded Article Method—This method involves copying an article from Ezine Articles or another popular directory and using free software to spin the character encoding of the article. This technique is little known, and strictly a Black Hat technique. An example will enlighten any confused readers. This is the letter ‘r’ in standard English encoding: r. This is the letter ‘r’ from a different, encoded set of characters: r. The two ‘r’ look exactly the same, but they are not. This Web application will change the encoding of any text that you enter into the input text area. The resulting article will look the same, but rather than the standard English characters the text will be replaced by different ones that look like them, but are not.

As a result if you copy and then paste the output to a word processor, most of the text will be marked as having spelling mistakes. The advantage of using this method is that the resulting article can be read by humans and will appear to computers to be unique and different from the original article from which it was copied. The disadvantage is that Google can examine the article, and easily find out what it is. Since this is a Black Hat method, penalties will follow. If detection and penalties are not in force yet, as many Black Hat SEOs claim, they will be in force soon. This is not the method I recommend. My rule of thumb for doing SEO is this: If a human being can find out that it is an artificial link by looking at it, then Google can find out too, or will be able to do so shortly.

4. Foreign Article Directory and Translation Method—This is the method I use to fill up my tier-two sites with quality content in seconds and without having to resort to expensive content-writing services. I use these Italian article directories as sources for my articles:

The are many other Italian directories, and there is no need to speak the language that the source article is in. I could go for Spanish, French, German, Portuguese, Finnish or even Japanese and Arabic ones.

    To start the job go to the Bing On-Line Translator. I have found that Bing is the service that does the job best for Italian articles. You can experiment with other services available on line, if you prefer.

    Type in the keywords that best describe the topic of your Web site in Bing and translate them to Italian or another language of the article directory. This will translate your keywords to the target language.

    Use the keywords translated by Bing to search in the foreign article directory for relevant articles.

    Copy and paste the whole article into Bing and translate it into English. Read the article carefully, and correct any gross translation mistakes.

    Add a link to your money site somewhere in the article. You can now use your article in your Web 2.0 property.

It is entirely up to you and your conscience whether you want to leave the credit to the original author and the link to his site. To see examples, you may wish to subscribe to Linkz, where I share all the links I use for my own sites.

The resulting articles will be readable, unique and convincing. They will be enough to persuade both Google and the moderators on Web 2.0s that your blog is genuine. This is a valid alternative to spending a fortune on content-writing services for your tier-two supporting sites without spending too much time writing content for them. If you enjoyed this tip, or have some of your own to add for generating content easily without giving away quality completely, make sure to comment below.

Article writing is the best source to promote the business and the site. One must accumulate the entire information essential to write the article and then think about the keywords people might use when probing for the information.

The SEO keywords must be incorporated in the article in such a way that they read naturally. Google exhibits the website in order of significance and Google ranking denotes the place of a website in the search results. An important on-page optimization principle to improve your site’s ranking on Google is not to make use of the keyword repeatedly but rather they should be optimized and must go with the flow.

The SEO articles must be written without any grammatical errors and spelling mistakes. The article should be given a suitable title and should be alienated into short paragraphs and sub headers.  It must be well written and be competent to give or present a new angle on the specific topic.

The Google penguin 2.0 update is a most important update that will have great impact on the rankings on Google for lots of sites. It has been called as Google penguin 2.0 update as it is the first update of penguin that has altered the algorithm instead of a refresh. This brand new generation of algorithms has a large impact on smaller areas and goes much deeper.  The range of Penguin 2.0 update varies by language and it is the basis of much conjecture these days.

How to scrape Yellow Pages with ScreenScraper Chrome Extension

Recently I was asked to help with the job of scraping company information from the Yellow Pages website using the ScreenScraper Chrome Extension. After working with this simple scraper, I decided to create a tutorial on how to use this Google Chrome Extension for scraping pages similar to this one. Hopefully, it will be useful to many of you.

1. Install the Chrome Extension

You can get the extension here. After installation you should see a small monitor icon in the top right corner of your Chrome browser.

2. Open the source page

Let’s open the page from which you want to scrape the company information:

3. Determine the parent element (row)

The first thing you need to do for the scraping is to determine which HTML element will be the parent element. A parent element is the smallest HTML element that contains all the information items you need to scrape (in our case they are Company Name, Company Address and Contact Phone).  To some extent a parent element defines a data row in the resulting table.

To determine it, open Google Chrome Developer Tools (by pressing Ctrl+Shift+I), click the magnifying class (at the bottom of the window) and select the parent element on the page. I selected this one:

As soon as you have selected it, look into the developer tools window and you will see the HTML code related to this element:

As is seen from the highlighted HTML line, you can easily define a parent element by its class: listingInfoAndLogo.

5. Determine the information elements (columns)

After you have learned how to determine the parent element, it should be easy to specify the information elements that contain the information you want to scrape (they represent columns in the resultant table).

Just do this in the same way that you did it for the parent element -  by selecting it on the page:

As you can see, the company name is defined by businessName class.

6. Tune the ScreenScraper itself

After all the data elements you want to scrape are found, open the ScreenScraper by clicking the small monitor icon in the top-right corner of your browser. Then do the following:

    Enter the parent element class name (listingInfoAndLogo in our case) into the Selector field, preceding it with a dot (*see below for why)
    Click the Add Column button
    Enter a field’s name (any) into the Field text box
    Enter the information item class into the Selector text box, preceding it with a dot
    Repeat steps 2-4 for each information item element you want to be scraped

*You need to put a dot before the class name because the ScreenScraper requires element definition in CSS Selector format only (with a dot before it)

After you enter all these definitions you should see the preview of the scraped data at the bottom of the extension’s window:

That’s it! I hope the tutorial is clear enough. But if not, feel free to write your comments below and I’ll give additional explanations.

Easy and Practical Web scraping in Python

This post is inspired by an excellent post called Web Scraping 101 with Python. It is a great intro to web scraping to Python, but I noticed two problems with it:

    It was slightly cumbersome to select elements
    It could be done easier

If you ask me, I would write such scraping scripts using an interactive interpreter like IPython and by using the simpler CSS selector syntax.

Let’s see how to create such throwaway scripts. For serious web scraping, Scrapy is a more complete solution when you need to perform repeated scraping or something more complex.

The Problem

We are going to solve the same problem mentioned in the first link. We are interested in knowing the winners of Chicago Reader’s Best of 2011. Unfortunately the Chicago Reader page shows only the five sections. Each of these sections contain award categories e.g. ‘Best vintage store’ in ‘Goods & Services’. Within each of these award category pages you will find the winner and runner up. Our mission is to collect the names of winners and runner ups for every award and present them as one simple list.

The Setup

Start python, IPython, bpython or any other interactive python interpreter of your choice. I shall be using IPython for the rest of this article.

A common starting point for most web parsing needs is getting a parsed web page from a URL. So let’s define our get_page function as follows:

from urllib2 import urlopen

from lxml.html import fromstring

def get_page(url):
    html = urlopen(url).read()
    dom = fromstring(html)
    dom.make_links_absolute(url)
    return dom

Within the get_page function, the first line downloads the page using urlopen function and returns it’s contents in the form of a string. The second line uses lxml to parse the string and returns the object representation of the page.

Since, most links in the html page will be relative pages we will convert them to absolute links. For e.g. a link like /about will be converted into http://www.chicagoreader.com/about. This makes it easy to call get_page function on such URLs later.

Selecting Page Elements

Next we need to invoke this function and select parts of the document. But before that we need to know which parts we need.

I prefer using CSS selector syntax compared to XPaths for selecting nodes. For examplem, the path to the same element in these two different syntax are shown below:

    CSS Path: html body#BestOf.BestOfGuide div#gridClamp div#gridMain div#gridFrame div#gridMainColumn div#StoryLayout.MainColumn div#storyBody.page1 strong p a

    XPath: /html/body/div[3]/div[2]/div/div[2]/div[5]/div/strong/p[2]/a

CSS paths might be longer but are easier to understand. More importantly, they are easier to construct.

On Firefox, you can use Firebug to right click on any page element to get it’s CSS path.

On Chrome, you will not be able to copy the CSS path but you can see it displayed on the status bar at the bottom

Selector Gadget

These CSS paths are extremely long and I wouldn’t recommend using them. They are too specific and tied to the overall document structure, which might change. Moreover, you can shorten a CSS selector path without affecting it’s specificity.

I recommend using a bookmarklet called Selector Gadget which elegantly solves both these problems. It also works across browsers.

First drag the bookmarklet to your bookmark toolbar. Open any page and click on the Selector Gadget to activate it. Now click on the element for which you want the CSS selector. Once you click an element, it will turn yellow and the CSS selector will appear in the gadget. Many other elements matching that selector will be also shown in yellow.

Sometimes, elements which you do not require are also matched. To eliminate that, click on an element you DO NOT want to match. Continue this process of selection and rejection till you get the exact CSS selector you want. Click on the ‘Help’ button for instructions.

Using iPython

Start your iPython interpreter and paste the lines of code, we saw previously:

$ ipython
Python 2.7.3 (default, Sep 26 2012, 21:51:14)
Type "copyright", "credits" or "license" for more information.

In [1]: from urllib2 import urlopen

In [2]: from lxml.html import fromstring

In [3]: def get_page(url):
   ...:         html = urlopen(url).read()
   ...:         dom = fromstring(html)
   ...:         dom.make_links_absolute(url)
   ...:         return dom
   ...:

In [4]: dom = get_page("http://www.chicagoreader.com/chicago/best-of-chicago-2011/BestOf?oid=4100483")

In the last line, you retrieve the initial page you would like to be scraped and assign its parsed DOM object into dom.

In the next three commands, cssselect function is invoked with the CSS selector “#storyBody p a” to get all the section links. The result is a list. Since we need just the URLs, we run a list comprehension across the list of links.

In [5]: dom.cssselect("#storyBody p a")
Out[5]:
[<Element a at 0x336ae90>,
 <Element a at 0x336afb0>,
 <Element a at 0x336c2f0>,
 <Element a at 0x336c3b0>,
 <Element a at 0x336c170>,
 <Element a at 0x336c350>]

In [6]: [link.attrib['href'] for link in _]
Out[6]:
['http://www.chicagoreader.com/chicago/best-of-chicago-2011-city-life/BestOf?oid=4106233',
 'http://www.chicagoreader.com/chicago/best-of-chicago-2011-goods-and-services/BestOf?oid=4106022',
 'http://www.chicagoreader.com/chicago/best-of-chicago-2011-sports-recreation/BestOf?oid=4106226',

 'http://www.chicagoreader.com/chicago/best-of-chicago-2011-music-nightlife/BestOf?oid=4106223']

In [7]: secns = _

Note that we are using the underscore ‘_’ symbol to refer to the result of the previous command. With this tip, we can avoid inventing names for temporary results. Also whenever we get a result worth keeping, we can name them in hindsight.

Finding all categories

Next we need to retrieve and parse each section page. It can be easily done with the following list comprehension. The second command is a nested list comprehension with two loops. As before, we just need the urls. All 389 of them, each representing an award category.

In [13]: doms = [get_page(secn) for secn in secns]

In [14]: [link.attrib['href'] for dom in doms for link in dom.cssselect("#storyBody a")]
Out[14]:

In [15]: categs=_

In [16]: len(categs)
Out[16]: 389

Finding the title, winner and runner-up

Next, open any url from the categs list and find CSS selectors for our items of interest. These three items are: award category title, winner and runner-up. Since cssselect function returns a list (even if only one match is found) we need to extract the 0-th element. Another function called text_content is applied to get just the information we are looking for.

In [17]: categ = categs[0]

In [18]: dom=get_page(categ)

In [19]: dom.cssselect("h1.headline")[0].text_content()
Out[19]: u'Best longtime cause worth fighting for\xa0'

In [20]: dom.cssselect(".boc1")[0].text_content()
Out[20]: 'Public school reform'

In [21]: dom.cssselect(".boc2")[0].text_content()
Out[21]: 'Recycling in Chicago'

Named Tuples - Ideal data structures for scraped input

Earlier, tuples were used for storing scrapped results. They use less memory compared to dictionaries. Recently, Python has support for named tuples which are much clearer to use and just as memory efficient.

The next few commands loops through all the award categories and adds a named tuple for each. To avoid fetching too many pages, I have truncated the list to only the first two items.

In [22]: from collections import namedtuple

In [23]: Award = namedtuple("Award", "title, winner, runnerup")

In [24]: awards = []

In [25]: for categ in categs[:2]:
             dom=get_page(categ)
             title = dom.cssselect("h1.headline")[0].text_content()
             winner = dom.cssselect(".boc1")[0].text_content()
             runnerup = dom.cssselect(".boc2")[0].text_content()
             a = Award(title=title, winner=winner, runnerup=runnerup)
             awards.append(a)

In [36]: awards
Out[36]:
[Award(title=u'Best longtime cause worth fighting for\xa0', winner='Public school reform', runnerup='Recycling in Chicago'),
 Award(title=u'Best historic building\xa0', winner='Chicago Cultural Center', runnerup='The Rookery')]

Power of Interactivity

For one-time scraping scripts, it is often best to use just the Python interpreter. I have tried to walk you through how I would attack the problem of scraping a set of web pages. Hope you found it useful!
