Microsoft Ignite 2015 : huge collection of information enhanced with more detailed resources to get you up-to-date with less time and effort

As some of you might know already, the Microsoft Ignite 2015 conference has started where Microsoft talks about where they’re going and what they’re doing. I watched the keynote, took many notes and added other relevant information which I’m sharing with you. Since so much was told and shown it’s certain I’ve missed stuff. As time goes by I will update the information in this post so it can be used as a reference.

I hope it’s useful. If you find any errors or have other useful resources or feedback, please leave a comment.

Update log:

-05-05-2015: Created Initial version including the keynote and additional information.

Brocade Certified vRouter Engineer Exam 170-010

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 🙂

The Openbox / Skybox , a cheap HD sattelite receiver that provides a lot of bang for the buck

Introduction

A couple of years ago I bought a Dreambox DM-800HD sattelite receiver. At the time, HD receivers were pretty expensive (300-400 euros) and there weren’t many good alternatives. I wanted additional HD receivers, but I wasn’t willing to pay 300-400 euros a piece. As such, I started investigating and found out that you could get an Openbox / Skybox HD receiver for about 70 euros including shipping, so I was quite interested and bought an Openbox S11. I’ve been using it for a couple of years now with a duo LNB with Astra 1 (19,2) and Astra 3 (23,5) and I’m very satisfied with it.

Advantages

  • It’s cheap and provides a lot of bang for the buck.
  • It provides good image quality.
  • It supports cccam.
  • It boots very quickly.
  • The remote is easy to use and comfortable in your hand.
  • You can timeshift / record to an USB drive.
  • You can play multimedia from an USB drive. Music, Images, Video (including MKV X264 !!!! ).

Disadvantages

  • Menus and options are very basic.
  • Only a single tuner.
  • Lack of support.
  • Custom firmwares are limited.
    • Hard to find out which firmware is best. Each has its own advantages and disadvantes.
  • Creating channel lists / favorites from the device itself is very time consuming and troublesome.
    • You can use external tools to create channel lists. By example Ali Editor / PVR800-Editor or MediaBox Editor Studio (MES). Even with these tools, the editing experience is not as good as I was used to with my Dreambox.
    • Already created channel lists / favorites can easily be shared using either USB or over the network using STBHD_LAN_MM.

Conclusion and advice

If you’re looking for a sattelite HD receiver that provides more bang for your buck, be sure to take a look at the Openbox / Skybox HD receivers. While I paid 70 euros back then, they can now be had for about 50 euros including shipping. Keep in mind though that initial configuration can require some manual work. After that you can simply re-use your configuration.

There are now many more versions available of the Openbox / Skybox however and I have to admit that it’s often not clear to me which types provide which advantages so be sure to take a look at this as well. Versions include the S9,S10,S11,S12,S16,S18,F3,F4,F5,X3,X4,X5,X6,S1000,S6000HD. Also keep in mind that there are a lot of clones available. Personally I just ordered the X6 here because I want a spdif output, I’ll write a review about it as soon as I receive it.

For people looking for HD sattelite receivers that provide more features, take a look at the Vu+ Solo2 or Duo2 that have been reviewed very well, but are also a lot more expensive.

Milestone of 50.000+ views reached !!! Thanks everybody.

My blog reached 50.000+ views. Thanks everybody, this really exceeded my expectation and motivates me even more to keep going. Special thanks go out to my fellow bloggers in my blogroll and to those who shared my posts on Twitter, Facebook and other social networks.

Even though my blog exists since January 2012, I really started to blog actively around August and ever since I’ve tried to keep posting on a regular basis. At the start of 2013 I even intended to blog every day. I was able to keep it up for a short while, but it was just too time consuming. Now I try to blog something at least once every 5 days. The blog post count is now at 170.

Personally I think Microsoft is on the right track. I’m really looking forward to all new Microsoft product (preview) releases including Windows 8.1, Windows Server 2012 R2 and System Center 2012 R2 and you can expect some blog posts about this in the near future.

Intel Haswell CPU available in June with VMCS shadowing – nested virtualization

In the beginning of June, the new Intel Haswell CPUs will be available. Besides the regular improvements like being faster, having better energy efficiency and having better graphics capabilities, these new CPUs will also include VMCS shadowing (Virtual Machine Control Structure Shadowing).

Basically it’s a feature that allows you to run a hypervisor (like VMware, Hyper-V, Xen Server) and create another hypervisor as a VM beneath it. This is also called nested virtualization.

Some of you might say, “Hey this is not new, I’ve already done this with VMware!”. The difference however is that the current method uses some sort of emulation that does not directly access the hardware. And even though it’s great for testing purposes, the performance is suboptimal.

With the embedded hardware supported VMCS shadowing in the new Intel Haswell CPU the nested hypervisor can directly access the hardware, which should improve performance. Also, it might even make it possible to use non-VMware hypervisors in a nested virtualization scenario.

Of course as always, we’ll just have to wait and see how the performance will be in real-life. It’s also not clear to me yet if hypervisors need to be updated to be able to leverage this option. Nonetheless, to me it sounds very promising and I look forward to playing around with it.

For more information read this great article by Gabe Knuth called “Could VMCS Shadowing (a.k.a. nested VMs) from Intel’s new Haswell processors be what Bromium needs to work in VMs?”. When you use the links in the article you will be able to get more information about the Intel Haswell CPUs including benchmarks and more detailed information about VMCS shadowing and use cases.

[EDIT 08-06-2013] Citrix is working hard on integrating VMCS Shadowing / Nested VMs in their products:
http://blogs.citrix.com/2013/06/03/intel-and-citrix-collaboration-to-bring-support-for-hardware-accelerated-nesting-of-hypervisors-into-market/#comments

If you’re planning to build / buy an Intel Haswell based computer or Home Lab, be sure to look into the confirmed USB3 bug in the chipset. Also unfortunately the DDR3 prices have increased substantially (almost 50%) over the last half year.

Q1 tablet sales doubled compared to last year. Apple is losing market share to Google and Microsoft

Even though pc sales are struggling, tablet sales are increasing rapidly. In Q1 2012 around 20 million tablets were sold, while in Q1 2013 over 40 million were sold.

What’s also interesting is that Apple is losing tablet market share to Google and Microsoft compared to Q1 last year:

My view on this:

  • Tablets are becoming increasingly more important.
  • Pricing is very important to tablet buyers since the Google Android tablets have been selling that well.
  • Apple needs to come up with something fresh if they want to maintain or even increase their market share.
  • Windows tablet sales haven’t been as bad as some believed. Of course there’s still a lot of room for improvement, but I think that it will keep gainimg market share. Especially when prices will become more competive and when the number of good apps increaes.
  • Windows 8 has been blamed for bad PC sales, but Apple Mac sales fell 7.5% as well. I believe it’s just that customers rather have tablets and smarphones instead of PCs. Also it might be possible that the PC market just has become saturated.

Microsoft – Surface Pro will be available before end of May in The Netherlands and many other countries

By the end of June, the Surface RT will be available in 29 countries and the Surface pro will be available in 25 countries.

It’s a pity we often have to wait for new products like the Surface Pro, but at least it’s coming to the Netherlands. And the waiting will also be over pretty soon, since it will be available before the end of May.

Personally I’m not a big fan of Windows RT, but I really love Windows 8 tablets. Since I’ve gotten my Windows 8 tablet, I have been using it as my main device. And apparently I’m not the only one as you can read in this great article:
“Two months with the Surface Pro and how it replaced my notebook”.

If you’re considering a tablet and are not yet sure if a Windows RT, Windows 8, Android or Apple tablet best meets your needs, read the comparison from one my previous blog posts.
