BIP 70 provides a mechanism so that a customer can be sure that they are sending a Bitcoin payment to the correct place. Before BIP 70, the customer would simply be presented with a Bitcoin address to send the amount to. This address could potentially be tampered with so the funds get sent to someone else. It is also not very user-friendly to be sending money to a random collection of letters and numbers.
Almost everything we do on the web will work better with autonomous blockchain technologies such as Bitcoin & ethereum because they allow systems to be built with unbreakable rules. Unlike Facebook, Twitter, Airbnb, Uber, PayPal or eBay, no executive authority can step in and say the rules don't apply to you.
Of all the blockchain technologies, Bitcoin is currently the most high profile. It is a massive area of growth in the startup eco-system.
SVGZ is just SVG compressed with gzip. Any web browser that supports SVG supports SVGZ as the files are just served with a gzip encoding.
It is part of the SVG standard:
According to the SI standard, there are 1000 bytes in a kilobyte.
There is another standard called IEC that has 1024 bytes in a kibibyte, but this is only useful when measuring things that are naturally a power of two, e.g. a stick of RAM.
In Mozilla Chairperson Mitchell Baker's DrupalCon Denver 2012 keynote she announced a new web authentication system they are developing called Mozilla Persona. It's a federated and open standard that respects privacy. I wanted to use this technology for my own projects so I created the Drupal module.
The slogan of the new Drupal website is:
Come for the software, stay for the community
This is the typical process by which people learn that Drupal's ultimate strength is its community, rather than its code base.
Websites are like human beings - any two websites can be very different and do very different things, but under the hood they are 99% the same. Any website (large or small) has very small unique code base, compared to the enormous software stack that it sits upon. Other components in the stack are typically:
Earlier this year Drupal core developers were getting a strange error message while developing Drupal 7:
Fatal error: Exception thrown without a stack frame in Unknown on line 0
This was causing a lot of head scratching because it doesn't provide any information about what caused it.
Drupal 7 uses exceptions more than any previous version of Drupal and this turned out to be the problem.
PHP exceptions are handled in one of two ways:
