This makes sense to me: Java PicketLink & Keycloak are merging. It was a little hard figuring out which identity/security project was for which tasks.
http://blog.keycloak.org/2015/03/picketlink-and-keycloak-projects-are.html
Together with new PicketLink 2.7.0.Final release, we would like to announce that PicketLink and Keycloak projects will be merging their efforts. Code base of both will get unified and new features will be developed in a singl...

#Powerwall comparison versus the most price-conscious consumer/hobbiest battery one can get, the Zippy Compact 5Ah 6S:

Powerwall vs Zippy Compact:
100kg vs 0.703kg
400V vs ~24v
10kWh vs ~0.12kWh
25Ah vs 5Ah
$3500 vs $51.39 (at HobbyKing's best offer, euro, up to 54.09 us)
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=58798

Slot this new contender into my spreadsheet of batteries and get these #Densities:
100Wh/kg vs 171Wh/kg
2.85Wh/$ vs 2.17Wh/$

31% more Wh/$ pitted against value-oriented hobbyist kit. Not bad at all Tesla.
It'd be interesting to know what amount of the 42% increased weight density is structural and what is the packaged electronics, and see where things would be battery to battery.

Zippy Compact, the latest addition to our Zippy battery series offers excellent performance and high quality in a "Compact" size. These packs provide the same capacity and discharge rate as our Flightmax line, but give you alternative sizes for applications that require a specific shape. Great for models with limited battery compartment space! Zippy batteries deliver full capacity & discharge as well as being the best value batteries in the hobby...

Interestingly, the Powerwall's 2kW/3kW (2.7/4HP) discharge continuous/burst does not compare well versus a single 0.7kg Zippy Compact, which can do 25C*5A*24V = 3kW. Are these batteries really something new in terms of radically high energy density to power density, or is this an artifact of expected use/the electrical subsystem?

I'm rather surprised at how little power is provided from Powerwall; I was not expecting air conditioners or microwaves to pose a problem. Certainly it'd drain the battery quickly, but your outdoor AC is often 240V * 15A = 3600 watts.

Virtual networking (pretend like you have networks) "newkid" OVN lands it's first end to end patchset. Newkid, because OVN is definitely new, but it rides atop the humongous #SDR (software-defined networking) work #OpenVSwitch been leading software defined networking with.

Great point-tracking by Greg. 2018, eh MS?

It'll be interesting to see whether Microsoft continues trying to build Azure as a .NET/MS Datacenter Operating System #DCOS , or whether they tack to making their provided infra more polyglot/Linux friendly. And how much of that shift would dilute the core base they have: those mass of devs that just want to show up to work, be handed comprehensive consistent all-in-one toolsets, and build, no thought required.
 
An important point that is missing from this article is that, if you run the numbers, it essentially means Microsoft is claiming they'll beat Amazon in 2018, that their cloud revenue will be higher than Amazon's in 2018.

Amazon currently has $6B in revenue from AWS with 50% annual growth, so you can run a back-of-the-envelope estimate yourself. One caveat is that the products aren't directly comparable, as Microsoft is adding in online Office (similar to Google Docs but no match at Amazon AWS) and a few other things. Even so, it's close to a claim from Microsoft that they'll overtake AWS in three years.

Passpoint based auto-connect on @Boingo's footprint. HS2.0 is an important enabling tech for Public Wi-Fi Calling.

Carriers are finally getting some federalized wifi infrastructure up. It's a pity it's the carriers alone here: this is the opportunity for infrastructure sharing that can help make disrupt carriers, not just make their reach ever more ubiquitous.

3.19.0-14 (previously seen in - 10). Three weeks, three #btrfs crash & burns. This Ubuntu #VividVervet release today might make for a rocky month of May for many.

Going back to an old kernel (3.13) is bootable/mountable.

IRC helped me find the bug:

Workaround; install 4.0:

Gonna be some pretty pissed off BTRFS users this ubuntu release.

In terms of power v. energy density tradeoffs, my Zippy reference leans hard into being energy dense. If you are looking at power dense, one might pick up a competing Turnigy 60C 6S 5Ah. A bit more expensive- $75 vs $51, a little more weight 864g v 703g, but continuous power density goes from 3kW (4HP) to 7.2kW (9.7HP), with a 10s burst to double that: 20HP- 5x as much as a Powerwall- in 1/116th the weight- woo hoo.

Turnigy batteries are known the world over for performance, reliability and price. It’s no surprise to us that Turnigy Lipoly packs are the go-to pack for those in the know. The Turnigy Heavy Duty Series have the amp draw capability you want for your high performance models at a price everyone can afford.  Turnigy batteries are equipped with heavy duty discharge leads to minimise resistance and sustain high current loads.

#Powerwall enthusiasm going on over here. No glossified, overly consumer targetted nonsense: Musk is delivering a machine of enormous base principles. And by that I mean, wahoo, it's freaking DC, and will probably serve all sorts of absurd load buffering tasks if you tried to ask that of it. Leaving the DC-AC conversion out makes me very happy, and it'll tie in nicely with solar. Unsure what kind of DC-DC is featured: is it just a boost for charging off wide range voltage input? Does it just maintain 400V across capacity levels? I dunno.

Wonderful example of #PatentsAreTerrible, a list of some pertinent speech recognition patents. Such a sham, such a crazy crazy sham. Computized analysis of a real world phenomena such as speech? Sure, has (general purpose, compute) machines in the process, patent it.

Tempted to pick up a Nexus 4G/Wi just for a $20/mo phone number that works with #GoogleFi. The data, at 10c/MB, is in classic American carrier form completely uncompetitive with anything (but at least it's pay per use), but a phone number that's not locked to ota, that might might might be coaxed to plug into a nice audio backend (Kamilio, webrtc, Serius, ad infinitum hypervoice possibilities) is a compelling box of toys to dig into.

Words you don't often hear together- efficient & rotary. Fits in a backpack 4HP rotary.
http://www.popularmechanics.com/military/research/a15233/liquidpiston-darpa-contract/

At some point we'll start making Chevy Volt (gas motor primarily for charging the battery pack) style land-drones. Looking forward to it. Looking forward to lighter small motors.
The LiquidPiston motor could be used in killer UAVs—and lawn mowers
