Free resources from Udemy

The folk at Udemy have put together good collection of youtube videos focusing on public speaking. The videos are short, and give good examples and advice on become a better speaker.

Udemy also has a several online public speaking courses for sale. But like many learning sites you may have to look around to find the one that best suits you (hint: click on the courses and check out the table of contents).

They gave me a enrollment of one of the courses, and I got video, downloadable PDF supplementary material and external links.

Personally I think that nothing can compare to getting up and giving a speech in a safe environment (such as at a Toastmasters meeting), but if you are looking for some fast-track information or want to supplement your training,  there is some good stuff to be found.

On a side note I have used Udemy for technical training as well, and they have lots of very good courses on a variety of topics. They are worth checking out.

Review: Cloudberry online backups

I have far too many friends that just don’t create backups, and far too many that backup to an external drive that lives next to their computers, which while marginally better is still basically useless.. Online backups are such a simple solution to this problem, but I have (until now) struggled to find a solution that really meets my needs.

In my quest to find the ultimate online backup solution, here are my requirements:

  • Compression of files before they are sent to the cloud. This saves in both upload time (bandwidth), and in storage cost.
  • Encryption of my data on my machine before they are sent to the server
  • “Trust no one”; only I hold the encryption key, and online data can only be decrypted by me
  • Versioning of files and keeping deleted files for a period of time
  •  Support of external (USB) drives
  • Robust

I have used two providers in the past (I won’t mention names), but one of them only supported internal drives, and the other deleted 50gigs of online backup because my external drive was unavailable.

So, I think that I may have finally found a product that does everything I need: Cloudberry Backup. Cloudberry have built a bunch of products that allow for connectivity to cloud storage services (their ‘S3 Explorer” is basically Total Commander for S3; a great product as well).

I have been using Cloudberry Backup for about a week now, and so far I am very impressed. Here are some of the features that impress me:

  • Optional compression
  • Block level backups (great for mailboxes)
  • Support for several cloud storage providers (S3, Rackspace, Azure and Google are just a few)
  • When using S3 (which is what I use), it gave me the option to use the Reduced Redundancy Storage, which is a little cheaper
  • Trust no one; however if I lose my backup key I will not be able to recover my files. The backup key is NEVER sent out
  • Many encryption options (AES256, DES, RC2, 3DES); file names are also encrypted
  • File Versioning (and deleting of old versions and retention of deleted files)
  • Scheduling
  • Real time backups
  • Server side encryption (s3 only)
  • Client side encryption


I tried to break it (by removing the external drives during backup), and it just picked up the error and waited for the drives be reconnected.

I then tested by deleting a few files and running a restore, it was a breeze. When I had a few questions, I got a rapid email response from them.

The software is super-simple to use; I will literally backuping up some folders in about 5 minutes. While it has some quite complex and technical features, anybody can use it. It is really easy to use. This is a great product which I think will be my backup solution.

I will post any updates.

Disclaimer: Cloudberry offered me a free license key, but it was only after I started my evaluation, and my evaluation is based on the 14 day trial that I am currently running. If it continues running like I expect, I will use that free key.
