I’ve been trying to find power meters for home. My criteria is that it has to support several sensors (because I want to know how much energy my computer and home cinema is spending) and it has to be wireless (because it more convinient this way). After researching a couple of hours, it doesn’t lok good. The number of choices is very small. The Voltcraft option is in doubt because all the information I can find is in german. And the only other working option that I found is Plogg.
Plogg looks easier to interface with. It seems that it’s a serial interface (AT-command) over Bluetooth or Zigbee. Or if you get the PloggZgb EAP you will be able to access the sensors via TCP/IP in your Ethernet LAN.
Quoting from the plogg webpage:
Supported Com Port Redirector (CPR) software maps virtual COM ports on a PC platform and redirects application data destined to an attached device. Rather than going out of the local COM port, the data is transmitted across the Ethernet network to/from the Lantronics XPort Direct using TCP/IP.
But at least it gave me the clue to look for Zigbee sensors as it seems that this technology is aimed at this type of devices. Although it went down that road and I didn’t find any real product there. I’ll post about it later.
By the way, if you are looking for power meters and you don’t need wireless or multiple sensors there are a lot of choices. Here’s a small sample:
An article on the Elektor magazine on home power meters caught my attention, particularly the wireless one. In the article they mention the Voltcraft Energy Control 3000, that is able to receive data (about energy consumption) from several sensor and can be connected to the pc via usb. The only problem is that the software that comes with it is in german only. The price is ok, 100€ + 35€ per sensor. But I cannot find any information on the actual format of the data that the Voltcraft Energy Control 3000 provides. I also impossible to tell whether or not special USB drivers are needed. It could be that it presents itselft as a hard drive and expose the date as a file. That would be the easiest way to interface with it and use my own tools to process the data. That would also make possible to connect to my MacBook Pro.
If anybody finds any information (in english) please leave a comment here.
It seems that is imposible to type the ˜ symbol (named also tilde,squiggle,twiddle,not,approx,wiggle,swung,dash,enyay,sqiggle) in Netbeans with a Swedish keyboard at least. It seems that it’s a long known java bug (bug 6353098, bug 6253172). At least I can use the Alt+126 code to type it.
UPDATE: It seems that Blinklist’s JSON export doesn’t work any more, and delicious now requires OAuth authentication for new accounts (which rubilicious doesn’t support). So I created another script to transform Blinklist’s CSV format to HTML bookmark format which you can import to delicious.
It’s done. I was suffering constant problems with BlinkList and I decided to move to del.icio.us. I also decided to rescue the old powermarks 3.5 bookmarks from the oblivion and import them to del.icio.us too.
BlinkList gives you the option of exporting your bookmarks in JSON format via the Options →Export links. (here is the link)
So grab the json file and save it somewhere in your disk.
Then use the following script to load all the bookmarks in the json file to del.icio.us. Just change the filename and username and password to suit your needs.
#!/usr/bin/ruby
require "rubygems"
require "rubilicious"
require "json"
require "date"
require "time"
def getTime(item)
dateadd = item['dateadd']
return Time.at(dateadd) unless dateadd == false
return Time.now
end
def getIsPrivate(item)
isprivate = item['private']
return "checked"==isprivate
end
def getTags(item)
item['tag'].gsub(' ', '_').gsub(',',' ')
end
json_string = File.new("blinklist20080710.json").read
result = JSON.parse(json_string)
r = Rubilicious.new('your_delicious_username','your_delicious_password')
i=0
for item in result do
i += 1
puts "#{i}: #{item['url']}"
#next if i < 3229
r.add(item['url'],item['name'],item['description'], getTags(item), getTime(item), true, getIsPrivate(item))
end
puts "ended"
If the script fails in the middle of the import don’t worry. just uncomment the “#next if i < 3229” and change the 3229 to the last bookmark id that was loaded. Rerun the script and it will skip all bookmarks up to the one you write there.
Loading the old powermark file into del.icio.us is a little more complex. You will need two files:

(This script will add all the links as private. If you don’t want that behaviour just modify the last parameter in “@context.r.add(@context.url,@context.name,@context.desc, @context.tags, Time.at(@context.date), false, true)” to “false”.)
Again, if the script fails in the middle of the import don’t worry. just uncomment the “#next unless i > 2261” and change the 2261 to the line number where you want to resume parsing the powermarks file. Rerun the script and it will skip all previous lines.
Hope it helps anybody that it’s trying to escape from Blinklist and/or Powermarks. I successfully imported 3299 blinklist bookmarks and 4000 powermarks bookmarks (a lot of dupes though). By the way, the first script will replace any previous bookmark with the same url and the second script will not. That’s the way I wanted it but of course you can change it. The parameter before the last one in the call to add is the one that control the “replace”. (see add documentation).
I just received my new MacBook Pro. I got this crash on the first day :-(. I put it to sleep and when I tried to restore… look what showed up on the screen.
Well, check that SSLv2 is enabled in Firefox’s about:config page first.
It seems that http://correos.es hasn’t realized that SSLv2 is a bit unsecure and they still force you to use that one. So to enable SSLv2 follow this instructions. I did, and now I can login.

There are some issue with carriage returns when printing the tags on screen that you can fix with the instructions in here.
I’m new in NetBeans and today I’ve been struggling a couple of hours with the simple task of attaching the source code for an external JAR (NetBean Library Wrapper Module).
Then I realized that I should been looking into the NetBeans Help first. The entry at Help → Help contents → Java Applications → Debugging Applications → Attaching Source Code to a JAR File explains how to do it.
first go to Tools→Libraries to open the Library Manager. Then click on New Library. Give it a name and select the jar. +But you should be careful when adding the Library, though. You must point to the JAR file INSIDE your module library wrapper (that’s <module library wrapper folder>/release/modules/ext/) NOT to the original location of the JAR. (As pointed out in the Help → Help contents → Netbeans Modules → Getting started → Module and Rich-Client Application Tasks: Quick Reference → Attach source code to libraries for debugging.)
Then you should add the library’s source folder in the Source tab of the Library in the Library Manager (you can point to the Javadoc as well).
NOTE: If you plan to attached the sources to the jar because you would like to stepping into the library’s code while debugging, or set a breakpoint in the jar, then you should make sure that the sources are marked for debugging. What?!? Yes, I know. This sounds weird but you have to do it. Start the debugging session in Netbeans open the Sources window (Window→Debugging→Sources) and locate the sources folder in the table, check the box “Use for debugging”.
