How to securely use xmlrpc

I like to post an article to wordpress through Byword or Ulysses. And those tools use wordpress’s xmlrpc.php.

By the way if you use xmlrpc.php with your own server , you might face up to infinite attacks which target xmlrpc.php. And I horribly experience it.

If you want to independently operate your wordpress blog on your own server , I recommend to block xmlrpc.php access from anonymous users with the code below.

<FilesMatch "xmlrpc\.php$">
    order deny,allow
    deny from all
    allow from [Your IP address]  // Allow the only your ip address
</FilesMatch>

Put the code above into your .htaccess file in the root folder of wordpress.

My experience on Upthere

Upthere is a kind of new concept of cloud service such as iCloud, Dropbox, Google Drive. Mostly cloud services save your data in both local and cloud. It could be beneficial for someone who wants to back up their data.

The problem is taking too much storage in your local storage

iPhone 16GB model has been criticized by users because it isn’t enough to fully use. The storage is too small to install bunch of applications from Appstore. Also the size of photos and videos taken by users is getting bigger and bigger.

Upthere provides a solution for it. It doesn’t take much space in your phone or notebook. It just saves thumbnails of photos or videos which are much smaller than fully saving them. So you can save your space with it.

Not enough to replace conventional cloud services

The problem that I faced with Upthere is organizing my documents in it. It suggests Loop as a tool for organizing. But, it isn’t enough to replace the conventional folders. Even they don’t provide tags to organize my files. So I hope that they provide a way for making it better.
