hpr1289 :: Short Xen Update From JWP

Released on 2013-07-11 under a CC-BY-SA license.

Show Title - Short Xen Update From JWP

In the Tilts 507 Rus came on as the Xen project manager. Had a lot to say about Xen but not about how xen is funded in the linux foundation by who.

In the course of preparing for the podcast I learned that is not easy to see who gives money to the linux foundation. But Oracle is on the board directors along with all the major players in the IT space.

I also learned weather it is type 1 or type 2 hypervisor it is not clear as it used to be. At work I do not get very many requests for anything but ESX, HyperV or KVM in that order. Once in a while a Xen or Oracle VM comes up. This might change with the open stack a bit but I am not sure.

A good start to look at it is here: http://www.ibm.com/developerworks/cloud/library/cl-hypervisorcompare/

A better view of the real state of type 1 vs type 2 is here

hpr1254 :: X2go Remote Linux server/client

Released on 2013-05-23 under a CC-BY-SA license.

With x2go you can access your desktop using another computer -- that means both LAN and internet connections. The transmission is done using the ssh protocol, so it is encrypted. By using the free nx libraries from NoMachine, a very acceptable performance in both speed and responsiveness is achieved. Even an ISDN connection runs smoothly.

This makes it is possible to connect your laptop to any computer with the environment, applications, and performance of the remote desktop. It is also possible to have a bunch of computers connected to a single server (terminal-server, thin-client).

Clients are available for Linux (Qt4), Windows, and Mac. The latter two can be downloaded directly as binary from the x2go homepage.

hpr0613 :: alternative investing and how the internet changes the game

Released on 2010-12-08 under a CC-BY-NC-SA license.
Shownotes from http://jwp5.wordpress.com/2010/11/16/alternative-investing-and-how-the-internet-changes-the-game/

For My hacker Public Radio spot.
Recently, I had a chance to review about 30 years of my investing and savings.
Being a live long member of the save 10% club and having been debt free for a number years I thought I needed a review.

Having been in the military I had picked almost all the wrong kinds of things to invest in in the pre-internet era that one could think of.
A few years ago when Ron Paul was running for President.
I stumbled upon his web site.
Having shared many views with Mr. Paul and him being a small town doctor from Texas.  I was very interested in what he invested in.
I read that he had about 50% of his assets in hard assets like Gold Coins and the rest T bills.
Of course he was debt free and owned his home and land out right as well. 

I use Etrade and I am slowy moving the mistakes of the Army.
Its just hard to get in touch with folks that deal with paper.

The reason I like Etrade so much is that they show the total loss or gain each investment right away.  No guessing you can see it.
You also pay as you go with them and it is very clear what you have to pay in total fee’s.

I like the treasury direct site as well.

But what really interested me.
Is what is coming.  And this is the Hacker part of that really says wow.
I have been a user of pay pal for a long time.
I have a German and American account with them and find its a great way to move dollars to euros with out a lot of over the top fees.
Most people do not think about having two types of money but I assure you the dollar is not worth very much today vs. the Euro.
Which is great for American Jobs. 
Being a Pay Pal user I a saw this Microplace site they have.
I used my pay pal ID and it worked.
There was no tricks or anything. 
You make a small loan to women in south texas or coco farms in the islands and they really pay you back.
I have done it for a few years and it made feel a lot better about sharing my money and getting a fair return.

I also look into owning a share of Windmill or truck or locomotive but the incoming costs are pretty high.  About 15K to starting in Germany to own a share of ship or locomotive.  I like this because its a set investment a train that works in the Hamburg harbor and its there you can go and see it on your web cam and see it work.  It pays back your entire principle over the 30 years of its life and it pays a share of the profit for that year.  I have not found very many American investments like that.  But have heard that some Oil trusts can do that.  Can I have a web cam of it working would be a qualifying point for me. 

Well enjoy and thank about it.
Keep it simple if you do save and watch fee’s.
The younger you start the easier it is.
And do not borrow money with credit cards or by car with credit or buy home unless you put 20% down.
Would be the only other advice.
I read book one time about wealthy barber and another about a guy who saved three years living expenses.
I used much from both. 
The one that really changed my life was when I had the living expenses worked out.
It changed how I felt about my Boss and what I would be willing do a lot. 
The spirit to take chance also came from that.

In any case I am off enjoy and be safe.


hpr0591 :: sdf and openvms deathrow

Released on 2010-11-08 under a CC-BY-NC-SA license.
first I wanted to share my contact information.
and my rss feed to my show http://jwplinux.libsyn.com/rss
I wanted to talk about two places that really helped me in learning about the command line. Both do not run linux one runs net bsd and the other runs open vms. Both are so geeky you need to beat it away with a stick.
I use really often and have learned so much from the use of sdf public access unix system. It was first done up in 1987 and I really like it. I saw it once in Seatle it is great thing to view. If you liked the old compuserve you are going to love this place. Its free but if you donate I think 10 bucks you get a lot more out of it.
The second place is death row vms I did a pod cast with bev a while back and its agreat place to do unix. its based on open vms which if you can not love it you must hate cute kittens to. Bev has a lot compilers there which can save you so bucks.
Free raid storage at both places.
free email at both places
free IRC at both places#
A lot that geeks like at both places
