Project Hammock: Undertow + Resteasy + Weld

3 Comments

John Ament, a long time lurker on resteasy-dev list has put together a lightweight combination of Undertow + Resteasy + Weld called Hammock.  We’ve gotten in some PRs from him to help make this a reality, hope to get more.  I’m hoping somebody puts together this combination with Netty too and contributes it.

Apple innovations I’d like to see

Leave a comment

  • Waterproof iPhone.  Lost 2 iphones last year to water damage.  Got so pissed I switch to the Galaxy 4 to get waterproof phone.  Android was a piece of shit, I couldn’t get used to it.  After 2 months I went back to the iphone.  (The form factor of the Galaxy 4 is kinda cheap too, but that wasn’t why I went back).
  • Bigger iPhone display.  Only thing I liked about the Galaxy 4.
  • Solar paneled iPhone.  Never got this iphone accessory, but I thought it was way cool.  Seems that Apple might think a solar power iphone would be cool too.
  • iCar.  I’ve owned some nice cars since the acquisition.  Still, I think their functions are weak.  I’d like to be able to plug my iphone into the car’s USB port and have it drive all display functions in the car.  I’d like to be able to use SIRI from my steering wheel.

What I don’t care about is:  iWatch, watches are so 1900′s.  iGlasses, WTF is google thinking?  iTV, I own a smart TV, still haven’t used any of its features.

 

Keycloak SSO Released – Alpha 1

5 Comments

Keycloak is an SSO authentication server and appliance for securing web applications and RESTful web services.  After 7 months of hard work, the Keycloak team (Bill Burke, Stian Thorgersen, Gabriel Cardoso, Viliam Rockai, Alexandre Mendonca, and Bolesław Dawidowicz) is proud to announce our first release, Alpha-1!  There’s still a lot to do, but there’s a lot you of features you can try out.  Besides written documentation, we’ve put together a bunch of video screencasts that you can view to learn and experience the features of Keycloak.

These are some of the core feature of Keycloak:

  • SSO and Single Log Out for browser applications
  • Social Broker. Enable Google, Facebook, Yahoo, Twitter social login with no code required.
  • Openshift Quick Start so you can deploy Keycloak on the cloud
  • Optional User Registration
  • Password and TOTP support (via Google Authenticator). Client cert auth coming soon.
  • Forgot password management
  • OAuth Bearer token auth for REST Services
  • Integrated Browser App to REST Service token propagation
  • OAuth Bearer token auth for REST Services
  • OAuth 2.0 Grant requests
  • CORS Support
  • CORS Web Origin management and validation
  • Completely centrally managed user and role mapping metadata. Minimal configuration at the application side
  • Admin Console for managing users, roles, role mappings, applications, user sessions, allowed CORS web origins, and OAuth clients.
  • Deployable as a WAR, appliance, or on Openshift.
  • Supports JBoss AS7, EAP 6.x, and Wildfly applications. Plans to support Node.js, RAILS, GRAILS, and other non-Java application

Go to the Keycloak website and follow the links to download, view documentation and videos, browse our source code, and submit bugs.

What’s Next?
As I said before, there’s still a lot to do, but here’s some things that will get in sooner rather than later:
  • Stan Silvert has written a Wildfly subsystem for Keycloak that didn’t get into the Alpha 1 release.  When we get this in, it will be super easy to secure web applications within a Wildfly environment.  You won’t have to crack open your WARs to add Keycloak configuration and enabling Keycloak security may be as easy as a doing a few clicks in the admin console.
  • Storage protection.  We’ll be adding support for more secure password hashing as well as storage encryption capabilities for the Keycloak database.  Its uber important to be able to have a 2nd level of defense for hacks.
  • Revocation policies. We need to be able to expire all tokens just in case somebody gets hacked and broadcast this information to deployed applications.
  • User session management.  This will allow you to view which users are logged in and give you the ability to log out one or more users.
  • Composite roles.  This will be the concept of a role group.  This will make it easier to change role mappings for a large set of users.

Thank You!

Finally, I want to give a huge thank you to everybody that helped make this release possible (Stian Thorgersen, Gabriel Cardoso, Viliam Rockai, Alexandre Mendonca, and Bolesław Dawidowicz).  Especially Stian for being such a great co-lead and Gabriel for doing such awesome design work.  This has been the best team I’ve been on since the good old JBoss Group days years and years ago, pre-aquisition when JBoss was young.

Geothermal HVAC Part 4: Costs, Savings, and Performance

Leave a comment

Costs

Tim might be upset with me sharing the costs,  but in my research it was kind of hard to find hard numbers and you should really know what you’re getting into before you waste people’s time.  The initial quote did not include electrician work nor yard work.

  • $48,500 for the drilling, ductwork, old system removal, and the ClimateMaster units.  Remember, our home was 4000 square feet and required two ClimateMaster units.  Your home, if smaller, could be less drilling and 1 less unit.
  • Roughly $2000 for the electrical work which was not included in the quote
  • Roughly $2000 for the yard work to replace bushes and rake and loam the damage property.
  • All this is covered by the Federal %30 Tax Credit!  (Credit not deduction), so the net install cost was around $37,000.

Performance and Savings

Early, but not complete returns are in.  Over the summer, compared to last year, it looked like I used 20-25% less electricity than the months of the previous year comparing 2012 to 2013.  My November 15th-December 15th electricity usage (3205 kWh) was about 2.5 times more than the time period last year (1300kWh).  Our total electric bill for this period was $320, so you figure about $200 for heating over that decently cold time period.

January and February 2014 were the most brutally cold months we’ve had in years and years.  Sub-zero  (below 0 degrees Fahrenheit) temperatures for often  days at a time and I don’t think we had a day warmer than 20F.  The system has 3 modes of heating.  Heating 1, which is ultra efficient.  Heating 2, which is full capacity, and Heating 3, which is auxiliary heating that uses additional full electricity to generate heat. The auxiliary, 3rd stage heat kicked in a few times when it when it was negative temperatures.  Still, with our geo system we were paying about $400-$500 a month.  Compared to the previous year (which was much warmer) we were paying > $1000 per month in oil for January and February.

Our total oil heating bill generally averaged about $4000 per year (October-April).  So, for a nice SWAG, you figure we’re saving about $3000 per year if you include the summer months savings too.  At todays prices, the pay off for the system is about 12 years.  BUT…Because my old system was so old and needed replacing anyways, I factor that cost into the equation as well, so the payoff is probably even shorter.

 

Geothermal HVAC Part 3: Installing In House System

Leave a comment

In this section I’ll talk about the work that had to be done inside of the house.

Our old system

Our old heating system had different forced-air ductwork than our cooling system.  The heating system used 1 oil burner with ductwork that went to both the 1st and 2nd floors coming up through vents in the floor.  The cooling system had an outside condenser that ran coolant through a pipe up to a blower in the attic.  The cooling system’s ductwork was separate from the heating and ran through our attic.

Our new system

For our Geo system, our guy decided to re-use the old heating ductwork to heat and cool the 1st floor.  The old heating ductwork for the 2nd floor was sealed off and not used.  The 1st floor ductwork was connected to a Water-to-Air ClimateMaster TTV064.  This unit was put in our basement where the old oil furnace was.

For the 2nd floor, the old cooling system’s attic ductwork was re-used.  A new blower was installed in the attic.  The coolant pipe used to connect the old blower to the outside condenser was also re-used and connected to a Water-to-Water ClimateMaster TTS038.  This unit was also put in our basement where our oil tank used to be.

Other work and Total Time

The attic ductwork was wrapped with additional insulation.  It also took some time to remove the oil tank, disessemble and remove the oil heater, old blower, and A/C condenser outside.  All and all, removing the old stuff and installing the new units took another 2 weeks beyond the drilling.

Geothermal HVAC Part 2: Installing The Loop

Leave a comment

I’m finally getting around to finishing up my write up on my Geothermal HVAC install.  In Part 1, I discussed why I was doing it and how I was able to get a quote.  For Part 2, I’ll talk about the outside drilling and close loop install.

The outide work took about 2 weeks to do and entailed drilling 3 bore-holes 350 ft deep, laying pipe in these holes, digging a trench to connect the holes, drilling into your foundation to bring the pipe into your home, and finally filling the holes and getting rid of extra material.  Be prepared for a part of your yard to be destroyed.  We required an area about 50′x30′.  The bushes in front on the left side of our house all had to be dug up.  The holes were about 15′ apart starting from the left side of the house .  While the holes themselves and the pipe connecting them only required a 5′ wide trench, there is a ton of material that comes from both the drilling and the trench that ends up taking up and piling up on the rest of the 50′x30′ space.  When everything was buried and that side of the lawn leveled out, we ended up having a lot of left over dirt which was spread out and dumped and packed in a different 20′x20′ area in our woods (yes we have a lot of acrage).  I must tell you, I was a bit freaked out by the damage to our lawn at first, but after only a few months you won’t even know drilling actually happened.  Nature repairs itself quite quickly!

The drilling equipment was quite large.  The drilling was done in late April and our yard was still quite muddy from the Spring thaw.  While they did put boards down on the lawn they left some deep tracks driving in that had to be repaired in the front of our lawn.  Also notice how close to the house they had to get.  This was fine btw!

This is the material left over from 1 borehole drill.

Here is the pipe they put into the holes.

Here is the trench they had to dig to connect the boreholes together and feed it into our house.  The trench was about 5′ deep and about 5′ wide.  They also drill into your foundation 5′ down to get the closed-loop pipe feed into your home.
