What is ParseHub used for?

ParseHub is a free website where you can find and download millions of apps for Android, iPhone, iPad, Windows Phone, Kindle Fire and even Windows 8.

You'll find free apps ranging from game titles, to business utilities, weather apps, sports apps, utilities, lifestyle apps, tools and much more. Use ParseHub to get your free apps and free money!

What do I get when I register? You get 50 ParseHub Tokens and 200 ParseHub Bonus Tokens. Why does ParseHub give tokens for? If you have friends on ParseHub you can exchange ParseHub Tokens and get ParseHub Bonus Tokens (up to the value of the ones you have sent)! What happens if ParseHub closes? ParseHub and all the content (apps, downloads, ratings etc) associated with ParseHub will be made private. ParseHub tokens will not be redeemable on the successor ParseHub.

Is ParseHub's content legal? ParseHub is an ad-supported website with no affiliation to any companies or corporations. All content is sourced from Google and other companies with an advertisement agreement with ParseHub. There is a limited license agreement that allows a company to use ParseHub's API but the company must pay for each app they download. However we are still waiting for the official licensing agreement so we don't know what the limits are. We will update this section as we get more information.

Is ParseHub safe to use? ParseHub uses a 3-tiered verification system for each app. Firstly, you can easily view the app details by simply clicking on the app name. Secondly, each app has a Verified status for its owners (ie it doesn't contain malicious code). Thirdly, you can download apps from verified apps by just tapping on the "Download" button, and it will automatically send a notification to the app owner about your download. We don't store any user data about the apps, ratings or reviews, so we don't have access to your login details or anything like that. Only the owners of the apps will see the results of what you do, and they can remove your access to the apps. We recommend users use an existing email for sending messages to other users so that your personal information doesn't show up in an email inbox.

Does Amazon allow data scraping?

I'm not sure if this is the correct place to ask this question, but I'm going to try here first.

I'm currently trying to figure out how to get data off of amazon's site.

For example, I want to scrape a list of books that have been reviewed, or books that are available at the best price. I want the data to come from a website that isn't even in english. Is this possible? I'm trying to think of ways to do it without actually taking it into the site, since I have no idea what language the text is in.

Thanks in advance. This is a simple use case of using a web crawler to crawl the product data. You could use Amazon's official REST API, or just use a tool like Scrapy (or bs4) to download the data.

Scraping is probably the oldest of all computer hacking.

It's been a very useful technique. I know many of you reading my blog might not have heard of scraping, and I thought I would start this post explaining what it is, some of the pros and cons of using a tool like ScraperWiki, and when to avoid scraping.

Before I get started, I want to make sure everyone knows there is no grey area here. Black and white, black and white. Scrape or don't scrape. Use a library or build your own. Don't scrape.

My first introduction to scraping came back in 2024 when I worked on an application called ScraperWiki, it was back then still in beta and I remember watching my friends, colleagues and competitors use it to do various things like view Twitter, RSS feeds, Facebook, Tumblr, Yahoo Pipes, Blogger, Wikipedia, Reddit, MySpace, Flickr and so much more. I also built one of the first APIs for it at the time called scrapbook so that developers could extend it themselves. We released two more versions, scrapbook 2 was available free and had new features like the ability to store custom data and use it locally and scrape with multiple browsers. Later scrapbook 2 was renamed scrapbookify and is now called ScraperWiki and this version also has the ability to store data locally. The current state of scrapbook has a lot of power as well as new tools, but if that's not enough and you want to go further than that, then I suggest you look at the full version. It allows you to do more and use APIs. We release scrapbook3 regularly so I'm happy to update this guide as more developers use it.

Some of the best and worst scraping examples. Ok, let's give a look at this video by Matt. On the negative side we can see what could be easily be fixed by running the page through a library like ScraperWiki.e. A good way to start would be to just add class attributes, meta tags, titles and descriptions.

But then we have a number of pages missing meta data so we end up going about fixing that which is not ideal. In terms of the good example I mentioned earlier when Matt looked at the Twitter page there is more data so there is less chance of him doing it again.
