Using the Python Requests module to POST documents to Solr Method Definition The first method accepts the Solr host URL and the JSON payload.  The auto-commit feature is turned off.  The second method will not POST any data, but it will commit any pending transactions. def post (host, data): headers = { "content-type" : "application/json" } params = { "commit" : "false" } return requests . post(host, data = data, params = params, headers = headers) def commit (host): headers = { "content-type" : "application/json" } params = { "commit" : "true" } return requests . post(host, params = params, headers = headers) Method Invocation The most important part of the method invocation is construction of the JSON payload: payload = { "add" : { "doc" : str (data) } } The payload has three aspects: The add  command tells Solr that a Create or Update is going to be perf...

Using module eval to Define Instance Methods in a Ruby Gem to Enable Per Model Configuration In the last post, I mentioned that I wrote a small gem to post changes to ActiveRecord models to Twitter. In that version, the configuration was handled by a YAML file. I wanted to evolve the gem so that developers could switch Twitter accounts for each model. Basically, I wanted to able to the use the following: class Place { :username => alastrina_gem, :password => QQQQQQ } end After a bit of tinkering and searching, I decided to use the following code in my gem. ALASTRINA_CONFIGURATION_FILE = config/alastrina.yml module Alastrina def self.included(base) base.extend(ClassMethods) end module ClassMethods def alastrina hash module_eval do def configuration throw "Missing #{ALASTRINA_CONFIGURATION_FILE}" unless File.exists? ALASTRINA_CONFIGURATION_FILE @config ||= YAML::load(File.read(ALASTRINA_CONFIGURATION_FILE)) end if hash[:twitter] def send_to_twitter? true end eval...

Using Intellij IDEA 12 for WebLogic Server 12c If you want to explore the latest EE features, you would need WebLogic Server 12c. However if you still have the IDEA 12 Ultimate edition, you will quickly find that it only supports up to WebLogic Server 11g (10.x)! However you can still make your IDEA 12 U to work with WLS 12c, and all you need is an extra "registry.xml" file under WLS home directory (eg: C:/apps/wls12120/registry.xml). This file will allow the IDEA to pickup and recognize your latest WLS 12c installation. <?xml version="1.0" encoding="UTF-8"?> <bea-product-information>   <host home="C:appswls12120" name="${env.HOST}">     <product format="1.0" name="WebLogic Platform">       <release level="12.0"         ServicePackLevel="6" PatchLevel="0"         Status="installed" BeaProgramGroup="BEA WebLogic Platform 12.0" StartMenu=...

Using multiple worktrees with git Modern development with Git is great. Its really easy to work on a feature branch, make changes, undo changes (oops), and share work with colleagues. However, there are challenges. If Im running tests on my local "beer" branch, I cant easily switch over to the "gin" branch to edit code. The local environment only has one feature branch checked out at a time. I can run tests, or add code, or switch branches, but I cant do two things on two different branches at once... But now I can! Thanks to Manoj Mahalingam S, I know understand the "git worktrees" feature which lets you easily use multiple branches at the same time. Thanks, Manoj!

Using a Single Parameter Value to Drive Visibility States of Many Elements in Many Family Instances Using some Visibility parameters and a simple formula structure, you can use a Revit family to store a collection elements and then selectively show them by using a single lookup value . This allows you to drive many visibility states (programmatically) through the modification of a single instance parameter value. In the case below, I created a Annotation family and multiple Yes/No visibility parameters, which I applied to Lines: Then, I make a VisibilityEnum integer parameter, and set the Yes/No parameter formulas to a given integer: You can also use Greater Than and other operators to show items that are visible across multiple visibility states: In the project environment, you only need to set one instance parameter to change visibility states: Finally, with some inventive use of Excel and Dynamo, you can drive this visibility parameter programmatically , even mapping the visibili...

Using the Nintendo Wii LAN Adapter on a PC Recently My Ethernet LAN Network Card couldnt find the Drivers and wouldnt work; so, Im using my genuine Official Nintendo Wii LAN Adapter as my PCs Ethernet Network card. And Like all PC Hardware under Microsoft Windows, Mac OSX, and even Linux Distributions; They require Hardware Device Drivers. When you Plug an USB Device in to Windows Itll register in the "Windows Device Manager". When Device Manager Runs itll detect the LAN Adapter as "AX88772", It cant find the Driver Software so youll have to download an Installer Manually; Dont worry I already found it on the Manufacturers website, and will add a Link to the Web Site in this Post. And remember these drivers are only for Nintendos LAN Adapter for the Wii; the Wii U LAN Adapter may use different Hardware. And other Vendors like Datel for example will use different Hardware/Drivers. A used Nintendo Wii LAN adapter isnt expensive; Gamestop sells them for around $12 USD....

Using Windows Keyboard with OS X � � If you�ve acquired a Macintosh, congratulations and welcome to the club. You�ll want to put your own personal stamp on it and this is an article to show how to use an external Windows keyboard with that Mac. Apple does sell keyboards and many people like to buy them so that everything matches esthetically. Electrically, though, not much distinguishes an Apple keyboard you buy at the Apple Store from a generic Windows keyboard you buy at Frys or Best Buy or even at the 24-hour CVS or Rite-Aid�s office supply aisle. The keyboard use the same USB connectors to plug into the computer and they use the same key codes to tell the operating system that you�ve pressed a particular letter, number or symbol.� One nice feature that I�ve found is that the media control keys lying above the function keys for play/pause, go back a track, go forward a track, increase �volume, decrease volume. work just fine with iTunes 12. �A nice added feature.� Now to the main qu...

Using the Selection Box Tool Anywhere in Revit Selection Box is a new tool in Revit 2016 that allows you to quickly crop a 3D section box around selected elements (without installing any addins). However, it doesnt always show up on the contextual ribbon. For example, if you are editing a family in-place... the tool doesnt seem to be available. However, we can work around this problem by simply adding the Selection Box tool to the Quick Access Toolbar. Select any object When you see the Selection Box tool in the ribbon, right-click on it and Add to Quick Access Toolbar Now, in various other modes in Revit, the tool will still be available :) download  file  now
