Just like in previous years the EMC Elect have a limited number of discount codes available for anyone who still needs to register for EMC World. The value of each code is $150! The amount of codes is limited and they expire on april 6, so if you need to register: follow up on this post and I’ll mail you your personal discount code.

  • The code can only be used for new registrations, if you already registered, the code won’t work.
  • Only 1 code per registration can be applied.
  • Codes only work for non-EMC people.
  • The code is worth $150.
  • If you know somebody who wants their own code: direct them to me and I’ll give them a code.

Hurry up! The codes stop working on April 6!!

Solar eclipses are not that uncommon

Total eclipse

In Europe it’s happening RIGHT NOW, but if you’re missing it, here’s a list of sites where you can see where and when the next eclipse will take place:

Tracking the FREAK Attack

Now what? Yet another vulnerability exposed?

On Tuesday, March 3, 2015, researchers announced a new SSL/TLS vulnerability called the FREAK attack. It allows an attacker to intercept HTTPS connections between vulnerable clients and servers and force them to use weakened encryption, which the attacker can break to steal or manipulate sensitive data. This site is dedicated to tracking the impact of the attack and helping users test whether they’re vulnerable.

At the moment it seems that only Firefox is safe to use! And needlessly to say that you should ALWAYS be aware of unsafe content. Try not to click anywhere unless you really trust the website!!!

The FREAK attack was discovered by Karthikeyan Bhargavan at INRIA in Paris and the miTLS team. Further disclosure was coordinated by Matthew Green. This report is maintained by computer scientists at the University of Michigan, including Zakir Durumeric, David Adrian, Ariana Mirian, Michael Bailey, and J. Alex Halderman. The team can be contacted at freakattack@umich.edu.

For additional details about the attack and its implications, see this post by Matt Green, this site by the discoverers, this Washington Post article, and this post by Ed Felten.

Enhance your WiFi by using beer!

Beer can WiFi booster

Bad WiFi reception

Bad WiFi reception is one of the most common annoyances these days. Especially in residential areas where every house has at least 1 access point and each family is working hard to fill the ether with their own signals. A quick fix can solve this problem relatively easy by using an empty beer can (a soda can also works).

The aluminum of an empty beer can enhance the WiFi-signal significantly. You could buy an expensive repeater, but a beer can is immensely cheaper (and is more fun to get too). Our good friend youtube shows us this instructional video.

Step by step

  1. Go to the supermarket
  2. Buy (at least) 1 can of beer (a premium brand will do better than some random cheap brand)
  3. Empty the can (don’t throw the beer in the sink at all times! Drinking is the preferred method!)
  4. Clean the inside of the can by flushing it with some water
  5. you will need a knife or scissors to open up the can and some material to fix the empty can to your router
  6. Remove the lid, used to open the can
  7. Cut off the bottom of the can
  8. Cut off the top of the can, leaving a small piece near the old drinking opening
  9. Cut the can from top to bottom at the opposite side from the drinking opening
  10. Carefully bend the metal so it (sort of) looks like a satellite dish
  11. Place the brand new dish shaped beer can on your access point, by sticking the antenna through the old drinking opening
  12. Fix the “dish” so it doesn’t fall off

steps

This little trick should enhance the signal strength by a factor 2 or 3. This only works for access points equipped with an external antenna. For antenna-less models you could try creating a somewhat larger dish and placing the whole access point on the bigger dish, but I don’t guarantee this works. You could for example use a keg, but I doubt that you can cut it by using scissors 😉

 

Top Blog websites Survey 2015

top vblog 2015

Vote for you favorite blog website!

Every year vSphere-land has a contest. You can vote for the top 50 VMware- and virtualization-related blogs of 2015. The blogs you can vote on are listed on vLaunchPad. Since about 2 or 3 years my website is listed there as well and so the idea is to vote on my website, so I end up in that top 50. This top 50 gets some extra attention, because these sites end highlighted and probably will attract some extra hits and that’s why we do this, right? –> extra hits!

My blog is listed on vLaunchPad so my site can be voted on! Again. In total about 400 blogs are in this list, so choose wisely, since all sites are probably worth reading.

How do I vote?

Visit the voting site and vote on me! But voting on 9 others is fair too, I guess. Let’s make sure www.50mu.net get in that precious top 50!
