CrazyRussianHacker Tries for a Darwin Award (RE Dry ice air conditioner)

This is really quite amusing – it was just last night (or, should I say early this morning?) that I had stumbled upon CrazyRussianHacker’s channel.  Quite amusing – he is rather funny and some of his ideas are definitely something I’m going to try out when we go cottaging with my family.

And yes, I did see he had a video for a dry ice air conditioner, but thought the idea silly and skipped that video.

It seems that Thunderf00t did not skip it – and has some things to say about it:

P.S.  CRH actually has a video where he criticizes some of his own earlier hacks and shows why and how they are to be voided, so he’s probably open to constructive criticism.  Should be interesting to watch his reaction…

Fundraiser to help re-settle Tibetan refugees

The Canadian government has recognized the difficult situation the Tibetan refugees are in and has permitted a number of them entry to Canada as sponsored refugees.  This means that, unlike other immigrants who are ‘sponsored’ by the government and thus get support from it to help them settle, the sponsors of these Tibetan refugees are the ones responsible for all.

Now, don’t get me wrong – they sponsors are quite happy with that!  And charity delivered directly from those who want to help to those who need the help is always kinder, more human-touch as well as more efficient than any help government would provide!

Yet, the more of us are helping, the more of us will feel great – and the more people will benefit, become happy Canadians, and lend a helping hand in their own turn.  I know, because earlier in my life, when I first escaped the persecution in my native land, I was so grateful for all the help I received from individuals first in Austria, then in Canada that now I am doing well, it makes me very, very happy to lend a helping hand in my turn.

So, please, help if you can – you’ll feel better for it!
