Dora Merges Three Hot Web Services: Pandora, Twitter and Bit.ly

picture-151Letting people know what music you are listening to has long been a staple of the web. The blogging platform LiveJournal has long had the “listening to” field, instant messaging clients like iChat and Google Talk added the ability to update your status based on the song you were listening to a few years ago, and now people are using Twitter to send our their music selections. Blip.fm is the best for this so far, but a new challenger rises in Dora.

Dora is actually an API mashup of three popular web services: the music streaming service Pandora, the micro-messaging service Twitter and the URL-shortening service Bit.ly. When you load Dora, you may think it’s just Pandora, but at the bottom of the page is the Dora overlay which provides you with an easy way to tweet out what you’re listening to. Before you do this, you must authenticate yourself on Twitter, but that gives you the ability to send a tweet out with the title of the song you are listening to (and a message in the remaining characters) with one click. There is also an option to append a link to the song shortened using Bit.ly.

Unfortunately, there are a couple weaknesses with Dora. First, before you can tweet, it authenticates your Twitter information over the OAuth protocol. This is nice as it’s a secure way to send information, but it adds a step to the tweeting out process. A lot of users are likely already signed into Twitter in their web browser, and could pass the song information that way. But the OAuth authentication wouldn’t be a bad way to go if Dora didn’t make you authenticate each time you revisit the site. That’s just annoying.

Another problem is that links Dora sends out to Twitter, link back to Pandora. The problem with that is that Pandora doesn’t allow you to access full versions of individual songs anytime you want to. Instead, it takes you to a page on Pandora for the song and gives you the option to preview it. Sure, you could create a new Pandora stations around this song, and it may pop up first, but that’s more complicated than it should be. Pandora has to do this because the rules of Internet radio streaming prohibit users from picking the individual songs they want to hear.

But Blip.fm, isn’t technically a Internet radio service, so it doesn’t have to adhere to such rules. And, as such, when you tweet out a song from Blip.fm, anyone can click on the link and immediately start listening to the song as well. Blip.fm also offers its own way to sign-in to Twitter without using OAuth. You have to give Blip.fm you Twitter name and password, but it’s more seamless.

If you’re addicted to Pandora, or really just want to share the titles of songs you are listening to, Dora is a nice solution. But if you want others to subject others to your musical tastes, Blip.fm is still the way to go. At least until it gets big enough to raise the ire of the record industry.

At CloudEXPO Silicon Valley, June 24-26, 2019, Digital Transformation (DX) is a major focus with expanded DevOpsSUMMIT and FinTechEXPO programs within the DXWorldEXPO agenda. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term. A total of 88% of Fortune 500 companies from a generation ago are now out of business. Only 12% still survive. Similar percentages are found throug...
Where many organizations get into trouble, however, is that they try to have a broad and deep knowledge in each of these areas. This is a huge blow to an organization's productivity. By automating or outsourcing some of these pieces, such as databases, infrastructure, and networks, your team can instead focus on development, testing, and deployment. Further, organizations that focus their attention on these areas can eventually move to a test-driven development structure that condenses several l...
The term "digital transformation" (DX) is being used by everyone for just about any company initiative that involves technology, the web, ecommerce, software, or even customer experience. While the term has certainly turned into a buzzword with a lot of hype, the transition to a more connected, digital world is real and comes with real challenges. In his opening keynote, Four Essentials To Become DX Hero Status Now, Jonathan Hoppe, Co-Founder and CTO of Total Uptime Technologies, shared that ...
Over the course of two days, in addition to insightful conversations and presentations delving into the industry's current pressing challenges, there was considerable buzz about digital transformation and how it is enabling global enterprises to accelerate business growth. Blockchain has been a term that people hear but don't quite understand. The most common myths about blockchain include the assumption that it is private, or that there is only one blockchain, and the idea that blockchain is...
Never mind that we might not know what the future holds for cryptocurrencies and how much values will fluctuate or even how the process of mining a coin could cost as much as the value of the coin itself - cryptocurrency mining is a hot industry and shows no signs of slowing down. However, energy consumption to mine cryptocurrency is one of the biggest issues facing this industry. Burning huge amounts of electricity isn't incidental to cryptocurrency, it's basically embedded in the core of "mini...

Every organization is facing their own Digital Transformation as they attempt to stay ahead of the competition, or worse, just keep up. Each new opportunity, whether embracing machine learning, IoT, or a cloud migration, seems to bring new development, deployment, and management models. The results are more diverse and federated computing models than any time in our history.
