The Static Blog
A quick note to mention that I added The Static Blog to my main web site, discussing the relocation of the blog you’re reading right now to this site.

Final Blog Move?
All links to each post and the RSS feed should now automatically redirect to the new location. This may have created some duplicates in your feed reader.
There is still some clean up to do to make the older posts look better, and I need to post a longer article to explain the rationale behind this, but for now everything should be working fine. The blog.benad.me domain will remain active as an option if something were to happen, but for the time being my blog should remain where it is.
Amazon Cloud Drive Backend for Duplicity
Actually, adding online storage services to duplicity is pleasantly easy to implement. If you have some command-line tool for your service that supports download and upload using stdin/stdout, file listing, and deleting files, then in an hour you can have it working in duplicity.
While in the past I did recommend CrashPlan as an online backup solution, I stopped using it in December. At first I used it because their multi-year, unlimited plans had reasonable prices, and was the only online backup (back in 2011) that had client-side encryption support. But over the years I ran into multiple major issues. In 2013, they started excluding backing up iOS backups done in iTunes in a transparent background update, even though they would publicly say otherwise. In fact, that hidden file exclusion list was pushed from their "enterprise" version, which has now moved to a much nicer version 5 while they abandoned their home users to version 4. In November, their Linux client started requiring Java 1.7, so my older client running in 1.6 kept downloading updates and failing to install it until the hard drive was full. Their pricing just kept increasing over time, making it difficult for me to keep reniewing.
I moved to iDrive, which is half the cost of CrashPlan and works pretty well, though I'm still a bit worried that I have to trust client-side encryption to some closed-source software. Also, if you back up anything beyond 1 TB their pricing becomes punitive.
The main issue that I have with all those backup services is that your backups become locked-in into online storage plans that are more expensive than competing generic cloud storage providers, and your valuable backups are held hostage if they increase their pricing. Even tarsnap, with its open-source client for the paranoid, locks you in an expensive storage plan, since the client requires some closed-source server software that only they host. I miss the days of older backup software like MobileMe Backup, where the backup software was somewhat separate from the actual storage solution.
Arq Backup looks more like this traditional backup software I was looking for. It can back up to a handful of cloud storage providers, with different pricing models, and many with free initial storage plans if you have small backups. The software is $40 per machine, and then you're free to pick any support cloud storage. The software isn't open-source, but the recovery software is open-source and documented, so you can vouch for its encryption to some extent.
But what if you're on Linux, or insist on an open-source solution (especially for the encryption part)? If you simply want to back up some files once, with no history, you can combine encfs, in "reverse" mode to have an encrypted view of your existing files, with Rclone. Note that with this approach extended file information may be lost in the transfer. If you want a more thourough versioned backup solution, Duplicity should work fine. It encrypts the files with GPG, and does file-level binary deltas to make backup files as small as possible. If duplicity doesn't support your cloud storage directly, you can store the backups to disk and sync them with Rclone. To make using Duplicity easier, you can also use the wrapper tool duply.
As for what cloud storage provider to use, it depends on your needs. If you can fit your backups in less than about 15 GB, you can use the free version of Google Drive. If you want a flexible pricing and good performance at the lowest cost, Google Nearline looks like a great deal at 0.01$ per GB per month. If you already have Office 365, then you already have 1 TB of OneDrive, though downloads can be a bit slow. The Unlimited plan of Amazon Cloud Drive has good transfer speeds and is worry-free, though Duplicity doesn't support it.
KeePass: Password Management Apps
Like many others, I'm a bit worried about the LogMeIn acquisition of LastPass. While they haven't drastically increased the pricing of LastPass (yet), it would be a good idea to look at other options.
A recommended option for open-source password management that keeps being mentioned is KeePass, a .NET application that manages encrypted passwords and secure notes. While it's mostly made for Windows, it does work, though clumsily, on Mac using Mono. Even when using the stable version of Mono, the experience is clunky: Most keyboard shortcuts don't work, double-clicking on an items crashes the software half the time, and it generally looks horrible. Still, once you learn avoid those Mono bugs, or you simply use that Windows virtual machine you have hanging around your copy of VirtualBox, KeePass is a great tool.
As for portable versions, there are of course a dozen or so different options for Android, so I haven't explored that yet. For iOS, the best free option seems to be limited to MiniKeePass. It doesn't sync automatically to any online storage, but transferring password database files in and out is simple enough that it should be acceptable if you only sparingly create new secure items on iOS.
Speaking of syncing, KeePass is server-less, as it only deals with database files. What can be done though with the desktop KeePass is synchronize two password database files with each other easily. The databases do keep track of the history of changes for each item, so that offline file synchronization is quite safe.
The fact that the original KeePass code was clean and documented enough to allow for so many different implementations means that using KeePass is pretty much "future proof", unlike any online password service. Sure, browser plugin options are limited and there's no automatic synchronization, but I would fully trust it.
