TreeSize Free, an already great tool got even beter

25 Feb

One of my favorite tools for years has been TreeSize Free. It is a small, easy, fast and portable tool that can be used to determine disk space usage of folders and files on a volume.

In the past it had some limitations that hindered me, but with the latest updates they’ve added great features that I really love:

  • TreeSize Free now scans network drives (except Windows servers and network drives within a Windows domain).
  • TreeSize Free provides a touch-optimized user interface as an option for Windows 8.0 and higher.
  • Users can now search for folders in the directory tree.
  • TreeSize Free supports selection of multiple files now, e.g. to delete or move them.
  • The scan performance on local NTFS drives (especially on SSD drives) has been increased.

So be sure to check out TreeSize Free if you hadn’t already or if you’re on an older version, download the latest version.

For those that run into the limitations regarding network drives with TreeSize Free, take a look at the commercial versions of TreeSize or other free disk space analyzer programs like Space Sniffer, WinDirStat, JDiskReport, Disk Analyzer Pro, Daisy Disk, Space Gremlin, etc.

Get Windows 8 MCSA certified between February 15th and May 31st and get a free Windows 10 exam

24 Feb

Microsoft has started a new campaign offering people that get Windows 8 MCSA certified between February 15th and May 31st  to get a free Windows 10 exam (697) when it is released. For more information about the offer see: https://borntolearn.mslearn.net/b/weblog/archive/2015/02/19/how-to-get-a-windows-10-exam-for-free

Based on the comments on the born to learn website it seems that this offer does not extend to people that are Windows 8 MCSA certified before February 15th … but I might be wrong. An alternative is to try to get access to free Microsoft Beta Exams by signing up as a Subject Matter Expert (SME) as described here: https://blog.bjornhouben.com/2012/09/17/how-to-get-access-to-free-microsoft-beta-exams/

VMware announces version 6.0 of their products (and why I hate the recertification program)

03 Feb

VMware version 6.0 products announced

Yesterday VMware announced version 6 of their products including vSphere 6, Virtual SAN 6, etc. I’ve read a bit on some of the products and to me it seems more of an evolution and less of a revolution. I’m also seeing similar concepts being introduced that Microsoft already implemented in Hyper-V. All in all I think the competition is good for the consumers. If you want to learn more about the VMware version 6.0 products, take a look at these sites:

Why I hate the recertification program

For some time now I knew that VMware would release version 6.0 of their products, but in the meanwhile I’m required to recertify before March 10th. I would’ve preferred to spend my time on version 6.0 of their products instead or on other technologies instead of being forced to focus it on version 5.5 to keep my certification status. Therefore my suggestion to VMware is to ensure that the recertification requirements take into account releases of new products. The ICT work field is already moving at an extremely fast rate and it is already hard enough to keep up without having to recertify (for multiple vendors and certifications).

Brocade Certified vRouter Engineer Exam 170-010

01 Aug

As I mentioned in a previous blog post, Brocade is offering free courses and exams.

Even though I’m not actually working in networking, I decided to brush up my networking knowledge by taking the 170-010 Brocade Certified vRouter Engineer Exam. I haven’t really done much with networking and CLI configuration in the last 7 years, but I still know the concepts from school where we did CCNA, CCNP, CCDA, CCDP. It took me about 2 days to study and I passed with 76% (passing score = 62%). In hindsight I should have played around a bit more in the vRouter itself 🙂

The exam wasn’t that hard, but a little knowledge about networking is expected, because the information provided by Brocade does not cover everything (or I missed something). For people who want to take the exam, you can use the resources described below. Make sure you’re very familiar with routing, OSPF, NAT and firewalling.

A student of mine informed me that Brocade is providing a free course and exam again. This time it is for Brocade Network Function Virtualization”
A while ago they also provided a similar offer for “Brocade Ethernet Fabric” which is also still valid apparently.

Take advantage of these offers if they are useful to you 🙂

Book review : Cloud Computing Concepts, Technology & Architecture

27 Jul

CCCTA_cover

Title: Cloud Computing Concepts, Technology & Architecture
Number of pages: 528
ISBN: 9780133387520
Released: May 2013

My opinion:

The book is well written, is vendor neutral, covers both business and IT aspects and contains many great diagrams. It also has a lot of useful references to external resources.
What I disliked, is that because of the vendor neutral approach some aspects are relatable enough (especially for people that don’t have a lot of working experience). I feel the book would have benefitted by providing more real-life examples of products or services.

The book is a good start for experienced people and will especially come in handy as a reference when getting involved in cloud computing projects. It will help understand vendor specific products and services better.

I would recommend people that are new to cloud computing (or that have very limited working experience) to first read a cloud essentials book like the one from Sybex before reading this book though.

To take a look at the book and its content, you can visit the book’s companion website: http://servicetechbooks.com/cloud
