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.

My RSS feeds for keeping up with ICT news/developments (Microsoft, VMware, Cloud and gadgets)

Currently, there are many technological advancements taking place every day. To keep up with them is already very hard. To make it a bit easier I use RSS feeds to quickly filter what I think might be of importance to me.

A list of the RSS feeds I currently use can be found here , but you can also download an XML export of my RSS feeds here for easy import to your preferred RSS reader (assuming it supports XML import). I also advise you to check Microsoft’s RSS feed index so you can customize it to your own needs.

I personally use Google Reader for my RSS feeds because then my RSS feeds will be accessible from everywhere as long as I have a browser and an internet connection. When you are often on the road without an active internet connection, a dedicated client with cached articles from the RSS feed might also come in handy.

PS: The Microsoft blog rss feed had many articles added daily and can be hard to keep up with, but you can pretty quickly weed out duplicate articles and articles in foreign languages.

I hope this has been helpful to you.

Good and cheap home wireless network solution

Over the last couple of years I’ve been using an Asus WL-500W wireless router to provide wireless access to our network. As a real tweaker I ofcourse replaced the default firmware with DD-WRT firmware and set the transmit power to maximum. This worked perfectly.

Lately however, my parents were experiencing some issues with wireless access from their phones and tablet. So the first thing I tried was to check if there might have been wireless networks on the same channel that were interfering. I checked this on my Windows laptop using Wi-Fi inspector and on the android phones and tablet using Wifi analyzer. Even though the number of wireless networks in the neighbourhood have increased substantially, here were no real indicators for issues. I did try optimizing and changing to a different wireless channel, but this also did not solve the issue. I think the increased transmit power might have taken its toll over the years.

Since I’m up-to-date regarding ICT developments, I know there is a new wireless standard 802.11ac under development and that recently a number of routers have been released based on the draft of this new wireless standard. The added value of these routers is mainly speed, but they are also very costly AND they require the client devices to be 802.11ac compatible as well (which they are not).

Instead I bought the TP-Link TL-WR1043ND plus three 8dBi anttenas (TL-ANT2408CL) because:

  • It is a good wireless router.
  • It can run custom firmware.
  • It is relatively cheap.
  • It has gigabit ethernet ports.
  • I do not need 5GHz (dual-band).
  • With the three 8dBi replaceable antennas, the range and signal strength will be unmatched in this price range.

The total cost of the router, 3 antennas and shipping was 65 euros at https://www.redcoon.nl. The wireless reception is perfect now and I recommend these products to everyone. Keep in mind however that wireless performance is very dependent on your environment and surroundings, so results may vary.
