Movement, behavior, force and vectors
Many projects include physical simulations or behaviors and object interactions, so here’s a quick walk-through of using vectors for forces and behaviors. We'll use the two-dimensional vec2 for now; however most of these concepts can be easily extended to vec3 for three-dimensional cases.
A vector can be used to store any property that has a magnitude and direction. It represents this in terms of components of principal axes. Examples include:
- absolute location (i.e. vector relative to the spatial origin)
- relative location (e.g. the path from object A to object B, or a line segment for drawing shapes)
- velocity
- acceleration, force
Position, velocity and acceleration
If an object has a location in space, we can move it by adding a relative motion vector to the location.
If we add this motion vector repeatedly, e.g. on each frame or simulation update, we create the illusion of continuous movement. In this case the motion represents a stable velocity, and the repeated addition is called integration. Put another way, the velocity is a discrete approximation of the location’s (first) derivative: modeling how it changes over time.
local vec2 = require "vec2" local draw2D = require "draw2D" local location = vec2(-1, 0) local velocity = vec2(0.01, 0.01) function draw() -- integrate velocity to location: location:add(velocity) print(location) draw2D.point(location.x, location.y) end
The second derivative of location is acceleration:
local location = vec2(-1, 0) local velocity = vec2(0, 0) local acceleration = vec2(0.01, 0.01) function draw() -- integrate acceleration to velocity: velocity:add(acceleration) -- integrate velocity to location: location:add(velocity) draw2D.push() draw2D.translate(location.x, location.y) draw2D.circle(0.05) draw2D.pop() end
Constraints
Pretty soon the object leaves visible space. You might want to handle this in different ways:
Limit movement to the boundary
-- prevent location component going below -1 if location.y < -1 then location.y = -1 end -- or more simply apply to all limits: location:min(1):max(-1)
Limit movement to a distance (i.e. a circular space)
location:limit(1)
Wrap movement at the boundary
Also known as toroidal space.
-- wrap at x boundaries: if location.x > 1 then location.x = location.x - 2 elseif location.x < -1 then location.x = location.x + 2 end -- or more succintly, for both x and y: -- to wrap in the range -1,1, first shift to the range 0,2, then modulo the boundary, then shift back to -1,1: location:add(1):mod(2):sub(1)
Execute arbitrary code at boundaries
For example, switch the direction of the velocity to point back to the center:
-- the fraction of energy retained when a bounce occurs: local bounce_factor = 0.9 -- bounce at ground level: if location.y < -1 then -- force the Y velocity to be positive: -- and lose a bit of energy due to the collision: velocity.y = math.abs(velocity.y) * bounce_factor end
Other constraints
Other forms of constraints can be limiting movement to a line, or path. In this case a new force can be applied toward the line of the path.
Another very common constraint is to limit the velocity to an absolute maximum: velocity:limit(max).
Forces
So far we have used a constant acceleration, which is physically unrealistic. Acceleration has to come from somewhere, and it can change magnitude and direction.
Acceleration was defined by Newton in terms of force: F = ma, which means “Force = mass * acceleration”. Therefore “acceleration = Force / mass”. Let’s wrap this into an object called “agent”:
local agent = { location = vec2(0, 0), velocity = vec2(0, 0), acceleration = vec2(0, 0), force = vec2(0, -0.1), mass = 100, } agent.move = function(self) -- calculate acceleration: self.acceleration = self.force / self.mass -- integrate velocity: self.velocity:add(self.acceleration) -- integrate location: self.location:add(self.velocity) -- limit position: location:min(1):max(-1) -- clear forces: self.force:set(0, 0) end agent.draw = function(self) draw2D.push() draw2D.translate(self.location.x, self.location.y) draw2D.circle(0.05 * self.mass * 0.01) draw2D.pop() end function draw() agent:move() agent:draw() end
In this case we have modeled an object that is continuously subject to a force of (0, -0.1). This would be something like the effect of gravity. Other continuous forces might be e.g. the effects of a force of wind.
To make it more interesting, we could consider that the wind may change direction over time. So we can model wind as a function that returns a force vector:
function wind() return vec2.random(0.1) end -- (in agent.move) self.force:add(wind())
We could also make the wind vary over space:
function wind(location) return location * -0.1 end -- (in agent.move) self.force:add(wind(self.location))
Other forces a body interacts may be approximately instantaneous, rather than continuous. For example, if mousepad is scrolled, we could add an instantaneous “jump” force:
function mouse(event, button, x, y) if event == "scroll" then agent.force:sub(vec2(x, y)) end end
Friction
So far our agent moves in a perfect Newtonian world: until a force acts on it, the velocity remains constant. In the world we are familiar with this rarely occurs, and velocity gradually decreases due to friction.
The simplest way we can model this is by scaling down the velocity on each frame:
-- (in agent.move) self.velocity:mul(0.9)
A crude simulation of air friction operates in the opposite direction to movement, with a constant magnitude. We can get the magnitude of a vector (it’s length) by Pythagoras’s theorem:
local len = math.sqrt(v.x*v.x + v.y*v.y)
Because this is so useful, there is a simpler method:
local len = v:length() -- or more simply: local len = #v
If we divide a vector by it’s length, we get a vector whose length is 1. This is a normalized vector, also known as the unit vector. Again, methods to do this already exist:
-- set the length of v to 1: v:normalize() -- return a new vector: the normalized (length==1) copy of v: local direction = v:normalizenew()
So now we can calculate a friction force easily:
local frictionCoefficient = 0.01 -- (in agent.move) local frictionForce = (-self.velocity):normalize():mul(frictionCoefficient) self.force:add(frictionForce)
Of course we could also create a function to vary the amount of friction over space.
Drag
A drag force is similar to friction, but varies proportinally to the square of the object speed, and to the surface area in the direction of movement. (For a circle the surface area is equal in any direction.)
local dragCoefficient = 1 -- (in agent.move) local len = #self.velocity local dragForce = (-self.velocity):normalize():mul(dragCoefficient * len * len) self.force:add(dragForce)
Gravitational attraction
Gravitational attraction applies in the direction from object A to object B. The magnitude is the product of the two masses multiplied by a constant factor, and divided by the relative distance squared.
local gravitationCoefficient = 1 -- (in agent.move) -- get the relative vector from self to the source of gravity: local relative = source.location - self.location -- get the length: local distance = #relative -- get the direction as a unit vector: local direction = relative:normalize() -- now calculate the force: local gravitationForce = direction * gravitationCoefficient * self.mass * source.mass / (distance * distance)
Special care needs to be taken here: if the distance between objects is very low, then the force can become astronomical. It makes sense therefore to limit the distance to a safe minimum:
local distance = math.max(0.01, #relative)
If you want to simulate gravitational attraction between all agents, you could put this into a loop over all the agents. Be careful to not apply gravitation to the object itself!
for i = 1, #agents do local source = agents[i] if source ~= self then -- insert gravitational forces end end
Springs
The direction of a spring force is the same as the relative vector between the ends.
The magnitude of a force of a spring is proportional to the deviation from it’s resting length. So if a spring’s natural length is 0.1, but the current length is actually 0.4, then the spring force is proportional to -0.3. The spring force also includes a scaling coefficient.
Spring forces can quickly lead to oscillation. A damping filter is usually required to allow oscillation to fade away.
Intentional forces
So far we have concentrated on physical forces external to an agent, but we can also consider the agent’s ability to apply forces to itself (locomotion). Different situations call for different strategies, and these lead to different forces being applied. Hunting, chasing, evading, random walk exploration, chemotaxis, avoidance, copying, centering, swarming…
This is discussed here, and in particular Craig Reynold’s excellent paper Steering Behaviors for Autonomous Characters.
Many agents
The way we have designed agent.move and agent.draw allows them to be applied to many agents. We could create a list of agents, and initialize them differently:
local agents = {} for i = 1, 100 do agents[i] = { location = vec2.random(), velocity = vec2(), acceleration = vec2(), force = vec2(), mass = math.random(200), -- "inherit" the move and draw methods from agent: move = agent.move, draw = agent.draw, } end
Then all we need to do is update our draw routine to visit each one of them:
function draw() for i = 1, #agents do agents[i]:move() end for i = 1, #agents do agents[i]:draw() end end
However, special care needs to be taken if the agent.move() function includes behavior between different agents (gravitation, spring forces, flocking, etc.). In order to make sure the effect of A on B is equal to the effect of B on A, you must separate the force calculation from the velocity/location integration into multiple passes:
agent.update = function(self) -- calculate forces and acceleration here end agent.move = function(self) -- update velocity, and location here end function draw() for i = 1, #agents do agents[i]:update() end for i = 1, #agents do agents[i]:move() end for i = 1, #agents do agents[i]:draw() end end

HRRR Archive at the University of Utah
Thank you for visiting this resource. With the expanded availability of archived HRRR grib2-formatted data now courtesy of NOAA and the Registry of Open Data on AWS, this archive hosted at the University of Utah is now being reduced. Users interested in the grib2 format are encouraged to switch to using the AWS archive, or a similar archive operated within the Google Cloud.
For users interested in subsets of HRRR data, our research group is now supporting a parallel archive in Zarr format. This new Zarr archive is also hosted by the Registry of Open Data on AWS.
Frequently Asked Questions
About the HRRR archive
What is this HRRR archive?
This HRRR archive is a collection of output from NCEP's High Resolution Rapid Refresh model. This is a model developed by NOAA ESRL and is run operationally every hour at NCEP's Environmental Modeling Center.
The operational HRRR generates hourly forecasts gridded at 3 km for 18 hours over the contiguous United States making it the highest spatial and temporal resolution forecast system run by NCEP.
HRRR Variable Details RAP/HRRR Diagnostic Details
HRRR analyses and forecasts are exceptionally valuable to the research community. For our research efforts, we maintained an archive of grib2-formatted HRRR files, which we also made accessible through this resource. With NOAA now having accessible archives of HRRR as well, our research group has now migrated to developing and supporting an archive of HRRR model data in Zarr format for research and other initiatives. This archive is supported by the Registry of Open Data on AWS, and more information on this new Zarr-formatted HRRR archive can be now be found via this resource here.
We expect to maintain some of this original grib2 archive for a period of time, but we do encourage users who are interested in the grib2 format to migrate to the cloud resources now supported by NOAA.
What files are contained in the remaining HRRR archive at the University of Utah?
Output files, in GRIB2 format, contained in the archive include:
- sfc: Surface fields for analyses and forecasts
- File format: hrrr.t[00-23]z.wrfsfcf[00-18].grib2
- File size: ~120 MB
- prs: Pressure fields for analyses
- File format: hrrr.t[00-23]z.wrfprsf00.grib2
- File size: ~380 MB
bufr: Vertical profiles available for KSLC, KODG, and KPVU- File format: [KSLC,KODG,KPVU]_[YYYYMMDDHH].buf
- File size: ~75 KB
- sfc: Surface fields for analyses
- File format: hrrr.t[00-23]z.wrfsfcf00.grib2
- File size: ~120 MB
Note: Not all hours are available for the experimental runs.
Became operational after July 12, 2018.
- sfc: Surface fields for analyses and forecast hours
- File format: hrrr.t[00,03,06,09,12,15,18,21]z.wrfsfcf[00-36].grib2
- File size: ~100 MB
- prs: Pressure fields for analyses
- File format: hrrr.t[00,03,06,09,12,15,18,21]z.wrfprsf00.grib2
- File size: ~205 MB
Note: Not all hours are available for the experimental runs.
Note: Some days and hours in our archive may not be available. Either the forecast wasn't run that hour (typical for the experimental models), or our download scripts failed to download everything.
What are GRIB2 files?
GRIB2, or Gridded Binary Version 2, is a standard file format used by meteorologists for model data sets. There are several useful tools for working with the data.
- wgrib2: a command line utility used to read GRIB2 files.
- pygrib: a Python module used to read GRIB2 files.
- cfgrib: a new Python module used to read GRIB2 files (version > 0.9.7 works with HRRR data). Works on Windows 😎
- IDV: a desktop application that can view many types of weather data.
- NOAA Toolkit: graphical software that can read and visualize GRIB2 files. I highly recommend this tool if you haven't used GRIB2 files before.
Where do the HRRR output files come from?
The operational HRRR (hrrr) and HRRR Alaska (hrrrak) is downloaded via HTTP from the NOMADS server.
Experimental HRRR (hrrrX) is downloaded via FTP from NOAA ESRL (credentials required).
HRRR Version Information
HRRRv1 was the operational model prior to August 23, 2016.
HRRRv2 was implemented at NCEP on August 23, 2016 beginning with the 12z run. We download the operational version from NOMADS. For more details on the HRRRv2 implementation, read the announcement
HRRRv3 was implemented at NCEP on July 12, 2018 beginning with the 12z run. Version 3 extends the forecast period for the 00, 06, 12, and 18 run out to 36 hours, but we have decided not to archive the f19-f36 files. Improvements in version 3 include updated Thompson microphysics, improved MYNN PBL scheme, updated land surface model with 15 second MODIS data, refined roughness lengths for certain land use types, and additional improvements in assimilation methods including lightning, radar radial velocity, and TAMDAR.
HRRRv4 was implemented at NCEP on Dec 2, 2020 beginning with the 12z run. This version makes more use of ensemble modeling methods and many improvements to model physics. Check out the Official HRRR Webpage for more information. Key upgrades include:
- Forecasts for the 00/06/12/18z are made out to 48 hours
- MYNN PBL update for better sub-grid clouds
- Aerosols sources/sinks
- Improved Land surface
- Assimilate GOES-16 Radiances and Motion Vectors and VIIRS/MODIS fire radiative power
- Ensemble 3km data assimilation
- Addition of smoke forecast variables (more information on these are available via this guide)
HRRR Archive Project History
This HRRR archive at the University of Utah was managed by Brian Blaylock and the MesoWest group on resources at Utah's Center for High Performance Computing.
Why did we archive the HRRR?
When this project began, there was no official HRRR archive that was publicly and easily available, to our knowledge.
This HRRR archive had been created to support various research endeavors in the Department of Atmospheric Sciences at the University of Utah. Things we do include:
- Initialize the Weather Research and Forecast (WRF) model with HRRR analyses as initial and boundary conditions. More info here.
- Model verification, where HRRR analyses and forecasts are compared to observed conditions.
- Retrospective analysis of high-impact weather events.
- Basic statistics of variables (max, min, mean, percentiles).
- Potential work with machine learning applications.
Where is the remaining HRRR archive at the University of Utah?
The remaining archive is physically located at the University of Utah Downtown Data Center in Salt Lake City, Utah. It is hosted on Utah's Center for High Performance Computing Pando archive storage system.
This object storage system is similar to Amazon's S3 storage Pando Archive Usage
What is the Pando archive?
Pando is a colony of quaking aspen trees in southern Utah, thought to be the oldest and largest living organism in the world, linked together by the same root system. According to Wikipedia, Pando is Latin for "I spread". The name is fitting for the CHPC object storage system because of its resilience and scalability, like the tree system.
The underlying software running Pando is Ceph, a project supported by RedHat. While Ceph can be configured in a few ways, in this archive Ceph manages the data objects with the Amazon S3 API. It is a separate "island" from the rest of CHPC file system so that output from other programs cannot write directly to it. Instead, files are copied to Pando through utilities like rclone or s3cmd.
Pando is built in three parts. All of these can be scaled to meet needs of the growing archive.
- 9 OSD Servers (16 8TB drives, each) - These contain the data objects.
- 3 Monitors - Monitors keep a map of the data objects. When a request for data is made, these monitors are contacted for the object map and return the object's ID.
- 1 RADOS Gateway node - You, as the client, make requests through this gateway for data downloads.

HRRR Statistics with Open Science Grid
I'm using the Open Science Grid to calculate long term statistics, calculated for +/- 15 days for every hour of the day for all the HRRR files in our archive. I calculate the following percentiles [0,1,2,3,4,5,10,25,33,50,66,75,90,95,96,97,98,99,100].
The HRRR analyses mean winds are comparable with the results of James et al. 2017.

Arrh!! For the second time in a week I have doubled booked myself :-(.
I need an alternative calendar system. Currently I use the daily pages in my journal to make a diary note. However this does not seem to be working well anymore. I think a combination of not being able to read my own writing and not copying family appointments into my journal are the main reason.
I have also have access to Google Calendar and a Zimbra Calendar. However they are on servers and I want something I can carry and use off-line. Since my Windows PDA does not sync with my Linux software I feel very stuck.
When I was using MS Outlook then the PDA thing worked very well...
Anyway -- sincere apologies to those who have been inconvenienced by my lack of control and effective tools

Hierarchical state machine metamodel:
It consists of states & transitions. A state may
contain other states.
See figure 'Meta Model for Hierarchical State Machine for
example HstmToStm' in file HstmToStm.pdf.
Flat state machine metamodel:
It consists of states & transitions. A state cannot
contain another state.
See figure 'Meta Model for Flat State Machine for example
HstmToStm' in file HstmToStm.pdf.
The transformation HstmToStm transforms a hierarchical
state machine model named hstm into a flat state machine model named stm, as
per the following mappings:
- A
leaf state in hstm is mapped to a state in stm.
- A
transition t between States s and s' in hstm is mapped to:
- A
Transition t in stm if both States s and s' are leaf states.
- If
State s is a leaf State and State s' is a non leaf State then Transitions
are created in stm from the state which is mapped to s, to all those
States in stm which are mapped to leaf states contained in s'.
- If
State s is a non leaf State and State s' is leaf State then Transitions
are created in stm from all the states in stm which are mapped to the
leaf states contained in s, to the State which is mapped to s' in stm.
- If
both States s and s' are non leaf States then Transitions are created in
stm from all the states in stm which are mapped to the leaf states
contained in s, to all those States which are mapped to leaf states
contained in s'.

Facebook Gaming snaps up streamer Disguised Toast
by AshIn the latest instalment of gamers leaving Twitch to stream elsewhere, popular streamer Jeremy “Disguised Toast” Wang has announced that he will now stream exclusively with Facebook Gaming.
Wang announced the news on Twitter with a short video, not dissimilar to how FaZe Ewok announced her move to Mixer.
Along with announcing his move to Facebook’s gaming platform, Wang also says that he donated the $20,000 production budget cheque to the Children’s Hospital of Los Angeles.
Wang says that he’s moved to Facebook Gaming in order to “reach more people around the world, continue to give back, and lose bets to [Facebook] chat.”
One of the biggest pros of Facebook Gaming is that viewers have no alias to hide behind, unlike on platforms such as Twitch, YouTube, and Mixer where people sign up with nicknames.
Facebook Gaming requires people to use their Facebook accounts, which show their full names, in order to follow and comment in chat, meaning people might hopefully think twice about what they comment.
While Facebook’s platform definitely isn’t as large or well known as Twitch, YouTube, or even Mixer, it’s still a growing platform and Disguised Toast has a decent audience, with over 243,000+ followers on Twitter alone.
The company’s acquisition of the streamer should see the platform getting more time in the limelight in the future. Whether Facebook Gaming will manage to grow into a platform that’s capable of competing with the likes of the more popular streaming platforms is another question entirely.
You can follow Disguised Toast on Facebook Gaming by following the embedded link here. Happy gaming!


Chapter 5 Practice Problem 1
Let’s make Anscombe's quartet
What is Anscombe's Quartet?
General Steps for Data Analysis
- Load data (of course, you need to have your data prior to this...)
- Clean data
- Check data distributions
- Data frame creation (subsetting the data)
- Check data distribution
- Summary statistics
- Exploratory data visualization
- Analyze your data
- Create a explanatory data visualization product
5.1 Set up an environement and load data
- Install R and R studio
- There are a couple options for R's Integrated Development Environment (IDE), but I would recommend R Studio if you do not have your preferred platform yet.
- There are a couple options for R's Integrated Development Environment (IDE), but I would recommend R Studio if you do not have your preferred platform yet.
- Create an R peoject file (optional, but recommended)
- name your file: myFirstR
- name your file: myFirstR
- Create an R script file
- name your file: anscombe
- name your file: anscombe
- Check and set up your work directory
- work directory: a place/ folder on your computer where your file locates
#check your work directory
getwd()
#set your work directory
setwd("/YOUR FILE PATH HERE/")
#mac users (if you made a folder on your desktop)
setwd("/Users/your-user-name/Desktop/myFirstR")
#PC users (if you made a folder on your desktop)
setwd("\\")
- Install and load packages you need for the project
- What are packages?
- Difference between install and load packages
- Install packages: You only need to do it once when you don't have a package installed in your R
- Load packages: You need to load them when you re-open R or want to use a package that is not loaded yet (package is already installed)
- Make sure you install and load all the packages you need in the beginning of your code
#install packages
install.packages("ggplot2")
install.packages("dyplyr")
install.packages("tidyverse")
install.packages("RCurl")
#load packages
library(ggplot2)
library(dplyr)
library(tidyverse)
library(RCurl)
#to check installed packages, run the code below or click "packages" on R studio
ip = as.data.frame(installed.packages()[,c(1,3:4)])
ip = ip[is.na(ip$Priority),1:2,drop=FALSE]ip
- load a dataset (if you are running R on R studio write this code to load data)
#loading data from a github repository. assign URL variable
url <- getURL("https://raw.githubusercontent.com/maiuchi/r_test1/master/test.csv")
#name a data frame (df) anscombe and read csv
anscombe <- read.csv(text = url)
- R already has this data installed... so you can also do...
data("anscombe")
5.2 Check data structure and clean data (done for today)
- Once you load the data up to R, the first thing you'd want to do is:
- Make sure your data is properly loaded
- function to use: View(name-of-dataframe)
- Check the structure of the data
- function to use: str(name-of-dataframe) or glimpse(name-of-dataframe)
- Make sure your data is properly loaded

Conflict
July 19th, 2015
Discuss a time you had a conflict. What was it about? What happened? When working on a project with a few other people. Everyone had their own opinion about how to do something. What was the source of the conflict? Lack of communication. What basic emotions did you feel upon analyzing the conflict? frustration What actions did you take to resolve your conflict? I simply communicated my idea and the fact that I was ok with trying someone else's idea first. If you could go back, what would you do differently, if anything? I would possibly try to communicate my idea and position earlier. What did you learn from this experience? Conflict can be easily resolved with proper communication.

Simply put, Resource-Tree is a file resource management system. Resource-Tree simplifies the process of turning data into a usable form. It creates an easy to access tree from files and directories; and also provides a convenient means for "freeing" data after use.
Where /path/to/file/or/dir/
has the directory structure:
dir
|- branch
| |- sub-branch
| | |- leaf.png
| | |- acorn.png
| |
| |- other-sub-branch
| |- ...
|
|- other-branch
|- ...
The following code creates a tree of readily usable images by
recursively iterating through directories to find files. For each file
found, the LOAD-FUNCTION
is called. In this case it's
LOAD-IMAGE
. If the LOAD-FUNCTION
returns anything other than NIL
the value returned is bound in a hash-table to a key which is a
keyword corresponding to FILE-NAME
with everything after the first
full-stop truncated and all spaces and underscores replaced with a
hyphen. All directories turn into branches when LOAD-PATH
is called
with the recursive flag set to T
(set by default). The same
"path-name to keyword" methodology is applied to directories.
(defun load-image (file-name)
(unless (string= "png" (pathname-type file-name))
(return-from load-image))
(let ((image (il:gen-image)))
(il:bind-image image)
(il:load-image file-name)
image))
(with-resource-tree (tree :load-function #'load-image
:free-function #'il:delete-images)
(load-path tree "/path/to/file/or/dir/")
(with-nodes (leaf acorn) (node tree :branch :sub-branch)
(il:bind-image leaf)
(il:flip-image)
...))
WITH-RESOURCE-TREE
creates an instance of RESOURCE-TREE
and
assigns it to TREE
with the remaining arguments being initialisation
arguments for the instance. LOAD-PATH
loads a file or directory into
the tree. The optional :PARENT-NODE-PATH
key specifies the path to
the parent node using a list. LOAD-PATH
may be called more than
once. WITH-NODES
creates variables bound to the specified leaves of
the provided node. NODE
is used to retrieve a single node (a leaf or
branch) from the tree path given to it. After the code is run, FREE
is called on TREE
which frees all nodes in tree using
FREE-FUNCTION
if FREE-FUNCTION
was set.
Prerequisites:
Optional:
Extract the source to the desired directory. Then, while in the
appropriate ASDF systems directory execute the following command,
where ../path/to/resource-tree
is obviously replaced as suitable:
find ../path/to/resource-tree -name '*.asd' -exec ln -s '{}' \;

tau.cf package¶
TAU Common Framework (CF) intialization and common objects.
-
class
tau.cf.
KeyedRecord
[source]¶ Bases:
object
Data record with a unique key.
Subclasses must declare a
__key__
member defining the attribute to be used as the key. Subclass constructors may use the key keyword argument to set the key value or, if the key keyword argument is not present, calls to the subclass constructor must pass the new key value as the first argument.Only one instance of a
KeyedRecord
subclass exists per key. Calling the constructor with a previously used key will return the existing instance, unmodified.Example:
class Foo(KeyedRecord): def __init__(self, a): self.a = a potato = Foo('vegtable') carrot = Foo('vegtable') steak = Foo('meat') for inst in Foo.all(): print inst.a >>> vegtable >>> meat potato is carrot >>> True carrot is steak >>> False
-
classmethod
find
(key)[source]¶ Find an instance.
Parameters: key – An instance key value. Raises: KeyError
– No instance has this key value.Returns: The instance with the matching key value. Return type: KeyedRecord
-
classmethod

class
tau.cf.
KeyedRecordCreator
[source]¶ Bases:
type
Metaclass to create a new
KeyedRecord
instance.Change object creation proceedure so that only one instance of a
KeyedRecord
exists for a given key argument. Overridding__new__
would be less creepy, but then we can’t prevent__init__
from being called on the returned class instance, i.e. the instance returned is reinitialized every time the it is retrieved. Using this metaclass guarantees we call__new__
and__init__
only once per class instance.To learn more about metaclasses: * http://docs.python.org/2/reference/datamodel.html * http://stackoverflow.com/questions/6760685/creating-a-singleton-in-python * http://stackoverflow.com/questions/100003/what-is-a-metaclass-in-python

TrackedInstance
[source]¶ Bases:
object
Base class for classes that need to keep track of their instances.
Each subclass tracks of its own instances separately. Unliked
KeyedRecordCreator
there is no restriction on the value of the class instance attributes.Example:
class Foo(TrackedInstance): def __init__(self, x): self.x = x class Bar(Foo): def __init__(self, x, y): super(Bar,self).__init__(x) self.y = y fish = Foo('haddock') chips = Foo('potatoes') fries = Foo('potatoes') drink = Bar('water', 'sugar') for inst in Foo.all(): print inst.x >>> haddock >>> potatoes >>> potatoes for inst in Bar.all(): print inst.x >>> water

The Sonestown Covered Bridge is a Burr arch truss covered bridge over Muncy Creek in Davidson Township, Sullivan County, in the U.S. state of Pennsylvania. Built c. 1850, the bridge is 110 feet (34 m) long, and was placed on the National Register of Historic Places (NRHP) in 1980. The bridge is named for the nearby unincorporated village of Sonestown; it was built to provide access to a gristmill, which operated until the early 20th century. The bridge construction is cruder than the other two surviving covered bridges in Sullivan County, with each Burr arch formed from six straight beams set at angles instead of a smooth curve. Despite being repaired or restored several times from 1969, as of 2016 the bridge was deemed "basically intolerable requiring high priority of corrective action" on the National Bridge Inventory. It is the shortest covered bridge in the county and as of 2015 had average daily traffic of 50 vehicles.

The Allegory of Faith is an oil-on-canvas painting by Dutch Golden Age artist Johannes Vermeer. Painted in the early 1670s, it is now in the collection of the Metropolitan Museum of Art in New York City, where it has been since 1931.
The painting depicts a finely dressed woman, representing the Catholic faith, sitting on a platform, with her right foot on a terrestrial globe and her right hand on her heart. She looks up, adoringly, at a glass sphere hung from the ceiling by a blue ribbon. Her left arm rests on the edge of a table which holds a golden chalice, a large book, and a crucifix. Resting on the book is a crown of thorns. At the bottom of the picture is an apple, and near that a snake squashed by a cornerstone. In the dim background hangs a large painting of the crucifixion of Jesus. Much of the symbolism, including the colour of the woman's clothing, her hand gestures, and the presence of the crushed snake and the apple, may have come from Cesare Ripa's emblem book Iconologia.<

Nicola Sturgeon celebrates 5 years as FM but her SNP looks increasingly like ‘cautious’ Scottish Labour at its peak
by James MitchellTOMORROW marks five years since Nicola Sturgeon became First Minister.
The SNP leader took over from Alex Salmond on November 20, 2014 — two months after the SNP and Yes movement were left heartbroken after the indy referendum defeat.
The five years that have followed have been dominated by the constitution — Brexit and independence.
And a mixed record at Holyrood has seen Ms Sturgeon come under fire over the NHS and education, but on the front foot on issues including climate change.
Her soaring personal popularity in the early days of her tenure has dwindled although the SNP are still riding high in the polls ahead of the General Election in December.
Tonight, Edinburgh University’s Professor James Mitchell — a leading expert on the SNP and its extraordinary rise since devolution — charts the past five years of The Nicola Sturgeon Show.
BY any standard, Nicola Sturgeon works hard.
And in five years as First Minister, that’s included creating an image that advances her career and politics.
She is on top of detail across a range of policies like no previous First Minister.
She is a brilliant communicator and debater – so it’s little wonder Boris Johnson is avoiding debating with her ahead of the General Election.
Ms Sturgeon gets out and about meeting people across Scotland. And she has a tight and very loyal group of close advisers.
But every strength has its downside.
Her focus on detail and frenetic range of activities leave little time for reflection.
She’s a great tactician, better at responding to events than long-term strategist.
Nicola Sturgeon has been lucky in the underwhelming leaders chosen by other parties, north and south of the border."Professor James Mitchell
As Health Secretary, she inherited a department riven with controversies and big challenges.
The challenges still exist — but she removed the controversies. Overturning decisions to close Accident and Emergency units in Ayr and Lanarkshire was popular but there was little effort to shift towards a more preventative approach to health that would limit the demand on services.
Her approach has been the same as First Minister. The watchword has been ‘careful as she goes’, a First Minister with a safe pair of hands.
Massive efforts went into creating her image by SNP HQ, guided by her husband Peter Murrell.
To many looking on, the Scottish Government has become The Nicola Sturgeon Show. But governing is about more than image. No other political leader inherited the level of support the SNP had when she became leader.
The extraordinary General Election result in 2015, when the SNP won 56 seats with 50 per cent of the vote, was her predecessor Alex Salmond’s legacy to her.
Her job was to increase support for independence beyond the 45 per cent in the 2014 referendum.
But her personal ratings have slumped since, and her party has fallen back electorally. The loss of 21 seats in 2017 would have finished most politicians.
But she survived as the SNP was still dazed by its 2014 referendum and 2015 General Election performance.
She still dominates Scottish politics but has been lucky in the underwhelming leaders chosen by other parties, north and south of the border.
But her safety-first approach is beginning to make her look uncomfortably like Jack McConnell, Labour’s last First Minister.
‘Doing less, better’ was his watchword. The danger facing her is copying him in just doing less. The SNP under Sturgeon looks increasingly like Scottish Labour at its peak — cautious, even conservative with a small ‘c’, moderate to timid. This can work in Scotland where the electorate is not as bold or radical as many pretend.
But the SNP is not any party. It wants independence and the SNP has made little, if any progress here despite conditions that should help.
Support for independence sits at around 50 per cent - not enough to be entirely confident of victory in a second referendum.
Boris Johnson ought to be a recruiting sergeant for the SNP. Labour is deeply divided and the Liberal Democrats look like they have blundered in their choice of leader.
But support for independence is stuck in the electoral doldrums.
Political leaders always risk becoming distant, out of touch with the wider public and no amount of manufactured meetings and selfies help.
It is inevitable, and can be guarded against only by ensuring those close to the leader are able and willing to confront her with realities.
Loyalty requires truth be told to power rather than warm reassurances. The image makers now need to make way for bold and courageous policy thinkers.

2 tents, 7 sleeping bags, 7 camp chairs, a dutch oven (more on this exquisite culinary companion later), two coolers, a whole bunch of fishing gear, and two 6 foot by 2.5 foot by 7 inch foam mattresses for the older crew who don't like to sleep on the camping pads the rest of us used.
 The reclining camp chair down under there somewhere was my birthday present.
No one expected 100 degree temps in the last week of September, so we were a little warm. Here is the view from the campsite. I think I may have selected the best one, site unseen, by careful analysis of the map. Such factors as proximity to dump station are quite important. I note that the water level is down
100 feet
from conventional depth.
We talked to several different people with the goal of getting the best spot to catch something, and ended up at "Wrinkle Cove". With the water so low so the fishing aint what it was and we got skunked pretty badly.
Here is the view from the campsite on Saturday afternoon. Robert and I spontaneously decided to swim across the lake, because it was too damn hot for anything else. I grew up on a large lake and have done that kind of thing many times before, but Robert is used to pools; and so swimming in a large lake make him nervous.
Hence the backup plan based on my Dad's excellent suggestion. We brought a blow up water toy that someone gave to us, and I tied a string to it as a backup in case Robert got tired.
Here we are maybe 1/4 of the way across. When we got even with the buoy slightly ahead of this position, Robert climbed up on the mattress, and I towed him the rest of the way across. I note that using a string as a harness is not such a great idea from a comfort perspective, but it did work.
Hard to see but that boy is getting a free ride here.
Success!! We achieved the far side with no problem. I had been talking with Robert and assuring him that there was nothing in the lake to be afraid of. I was hoping that he would swim himself for more of the return trip, and was surprised when he said he was going to "go for it".
A final wave before the return trip. Robert swam back all the way by himself! Totally sweet swim on such a hot day.
My birthday desert was cobbler cooked in the dutch oven in coals. Old boy scout learning put to good use.
Rasberry peach cobbler! Yum.
Thanks Mom for the great treat cooked off the grid!

Apache Isis™ is a framework to let you rapidly develop domain-driven apps in Java. This app has been generated using Isis' simple archetype, which configures Isis' most commonly used components as part of a very simple and purposefully minimal application.
The app itself consists of a single domain class, SimpleObject, along with an equally simple (factory/repository) domain service, SimpleObjects.
Alternatively, if you'd like to start from a richer starting point, you might want to use the quickstart archetype, which generates a straightforward "todo" app.
The Isis components that are configured in this app are:
| Component | Access URL | Description | Further info on the Isis website |
|---|---|---|---|
| Wicket Viewer | wicket/ | Provides a generic UI for end-users, built with Apache Wicket™ | wicket viewer |
| RestfulObjects Viewer | restful/ | Provides a RESTful API conformant with the Restful Objects spec | restfulobjects viewer |
| JDO Object Store | n/a | Persists objects using JDO/DataNucleus; configured to use HSQLDB in-memory database | jdo objectstore |
| Shiro Security | n/a | Provides authentication and authorization, using Apache Shiro™ | shiro security |
The default user/password is sven/pass (as configured in the shiro.ini file).

Many methods of graph drawing, such as force layouts, do not assign intrinsically-meaningful positions to nodes: the position is only approximate, in the hope that related nodes appear nearby. While intuitive, these methods arguably make poor use of the most effective visual channel (that is, position), and in the worst case produce an indecipherable hairball.
Enter Krzywinski’s hive plot. Hive plots define a linear layout for nodes, grouping nodes by type and arranging them along radial axes based on some property of data. The explicit position encoding has the potential to better reveal the network structure while communicating additional information. Hive plots can also be extended to show aggregate relationships.
Each node above represents a class in a software library. Nodes are divided into three categories. The 12 o’clock axis (the top) shows source nodes—classes with only outgoing dependencies. The bottom-left axis shows target nodes with only incoming dependencies. The remaining nodes in the bottom-right have both incoming and outgoing dependencies; these are duplicated to reveal dependencies within this category.
This grouping immediately reveals much about the different classes. The highest-level implementations (such as layouts and controls) are arranged in the top axis, while interfaces and internal abstractions are in the bottom-right. Heavily-interconnected classes, such as Transitioner and Data, are emphasized by numerous links. The handful of decoupled classes (those with only incoming dependencies) are delineated in the bottom-left. A variation of this design only considers dependencies across package boundaries, painting a different picture.
In a standard hive plot, nodes are sorted by link degree. This example instead arranges node by package, grouping related classes. This better reveals the “macro” structure of the dependencies, while demonstrating the great flexibility of hive plots—you can use any number of methods to group and position nodes along each axis, customizing the layout to suit your needs.
Want more? Other approaches to network visualization are matrix diagrams and hierarchical edge bundling. See also these simpler examples of hive plots. Feedback or questions? Discuss on HN.
Special thanks to Rich Morin for assisting in the implementation of hive plots in D3!

The Greek God Pan, the god of the open air, was a great musician. He played on a pipe of reeds. And the sound of his reed-pipe was so sweet that he grew proud, and believed himself greater than the chief musician of the gods, Apollo, the sun-god. So he challenged great Apollo to make better music than he.
Apollo consented to the test, for he wished to punish Pan’s vanity, and they chose the mountain Tmolus for judge, since no one is so old and wise as the hills.
When Pan and Apollo came before Tmolus, to play, their followers came with them, to hear, and one of those who came with Pan was a mortal named Midas.
First Pan played; he blew on his reed-pipe, and out came a tune so wild and yet so coaxing that the birds hopped from the trees to get near; the squirrels came running from their holes; and the very trees swayed as if they wanted to dance. The fauns laughed aloud for joy as the melody tickled their furry little ears. And Midas thought it the sweetest music in the world.
Then Apollo rose. His hair shook drops of light from its curls; his robes were like the edge of the sunset cloud; in his hands he held a golden lyre. And when he touched the strings of the lyre, such music stole upon the air as never god nor mortal heard before. The wild creatures of the wood crouched still as stone; the trees kept every leaf from rustling; earth and air were silent as a dream. To hear such music cease was like bidding farewell to father and mother.
When the charm was broken, the hearers fell at Apollo’s feet and proclaimed the victory his. All but Midas. He alone would not admit that the music was better than Pan’s.
“If thine ears are so dull, mortal,” said Apollo, “they shall take the shape that suits them.” And he touched the ears of Midas. And straightway the dull ears grew long, pointed, and furry, and they turned this way and that. They were the ears of an donkey!
For a long time Midas managed to hide the tell-tale ears from everyone; but at last a servant discovered the secret. He knew he must not tell, yet he could not bear not to; so one day he went into the meadow, scooped a little hollow in the turf, and whispered the secret into the earth. Then he covered it up again, and went away. But, alas, a bed of reeds sprang up from the spot, and whispered the secret to the grass. The grass told it to the tree-tops, the tree-tops to the little birds, and they cried it all abroad.
And to this day, when the wind sets the reeds nodding together, they whisper, laughing, “Midas has the ears of an donkey! Oh, hush, hush!”

The documentation for this struct was generated from the following file:


Hello, firstly I would like to thank you for purchasing "VELES - Premium WordPress Theme".
If you have any questions that are beyond the scope of this help file, please feel free to email.
PHP Coding: Orange Idea (www.orange-idea.com)
Design: Orange Idea (www.orange-idea.com)
Contact<EMAIL_ADDRESS>Compatible with: WordPress 3.2+
Version number: 1.0
Release date: January 20, 2012
This documentation will teach you how to set up and use the VELES WP Theme. The theme is very easy to use and we are here to guide and help you, so please read and follow the documentation and if you have further questions please feel free to email via my user page contact form. This documentation is more of a reference work if you do not know what to do, or if you are not familiar to WordPress.
This is a short walkthrough of WordPress installation. This part will be useful if you install WordPress theme for the first time.
Before you start, you must have a server that supports PHP and provide access to a MySQL database. First step is to install WordPress on your server. You must download WordPress ZIP file from http://wordpress.org/download/, extract the files and you’ll get a folder named "wordpress". Now you must upload all files from this folder to your server via FTP client. Content from this folder must be located in the root of the website, so that this location will be the URL of your website.
If you will access your site URL now, you should see only a note: "There doesn’t seem to be a wp-config.php file…".
In next step you must manually create a configuration file. Open the wordpress folder and make a copy of file named wp-config-sample.php. Change name of this copy to wp-config.php and open this file in an editor, it can be a simple editor like Notepad.
Now you must modify this file and add information about your database. You need to have four data pieces to do this:
You must fill these four data pieces into your wp-config.php file. This is how it would look like for our example data:
/** The name of the database for WordPress */
define(‘DB_NAME’, ‘wpdbname’);
/** MySQL database username */
define(‘DB_USER’, ‘username’);
/** MySQL database password */
define(‘DB_PASSWORD’, ‘123456789’);
/** MySQL hostname */
define(‘DB_HOST’, ‘mysql.yourdomain.com’);
Now go back to browser and reload your site that is pointing to your WordPress installation. If all the data from wp-config.php file is correct you will see the installation page:
Just fill in the name of your blog and your email address, and click on Install WordPress button (this data can be changed later). Now you will see the last page of WordPress installation process that shows the default Username, which is always admin, and a randomly generated Password.
You must remember this password or just copy and paste it to a temporary file. After this click on Log In button or enter admin panel by pointing to your browser to http://yourdomain.com/wp-admin. You will be redirected to admin panel login page where you have to enter default Username and randomly generated password. You can change Username and Password when you are logged into admin panel. Just click on Username (admin) in the top right corner of admin panel. And that’s it, now you can install your theme to your WordPress installation. And that’s it, now you can install VELES Theme to your WordPress installation.
You can either choose to upload the theme to your server via FTP (only upload the unzipped folder "VELES" into the folder wp-content/themes/ ) or via wordpress upload function. After copy WP Theme you must login to admin panel (or refresh this panel if you are still logged), go to Themes (under Appearance, on the left WordPress menu) and activate VELES Theme.
Login to admin panel.
Go to Appearance → Themes and click on the tab Install Themes. Choose upload.
Click on Browse..., select the downloaded theme file and click in Install Now
.After successfull installation click on Activate or go to Appearance → Themes and click on Activate to activate the newly installed theme.
Next you will see a new submenu item Appearance → VELES Options. Use the submenu items VELES Options and menu Portfolio to manage the theme settings.
After activation, you should see the VELES Theme at the top of the admin panel:
Important!
For first time activation, you need to hit Options Reset to store your default options in the database and then hit Save All Changes (Under menu Appearance → VELES Options).
As soon as you install one of our theme, you have several theme settings that we want to introduce here.
The general section allows you to edit the "global" settings of your website: set the logo image, favicon, pick a background color, select a background pattern.
Under the HOME PAGE STYLE I tab, you can customize the appearance of the home page elements
Under the HOME PAGE STYLE II tab, you can customize the appearance of the home page elements
Under the HOME PAGE STYLE III tab, you can customize the appearance of the home page elements
Under the About Us tab, you can customize the appearance of the ABOUT US page elements
Under the Service tab, you can customize the appearance of the SERVICE page elements
Under the Contact Page tab, you can customize the appearance of the CONTACT page elements
Under the Footer tab, you can customize the appearance of the FOOTER elements
Log in to your WordPress Administration Panel (Dashboard).

2. Module Configuration
The full set of available configuration options is documented in Appendix A; this chapter serves as an overview of the configuration process and provides examples of how the options may be used.
Broadly, the process for configuring Envy is:
- Add non-plugin
init.vim
configuration. - Enable the plugins you want to use.
- Specify any additional dependencies the plugins may have.
- Add per-plugin configuration.
- Pre-fetch and pin any shortname plugins (see chapter 3).
Non-plugin Configuration
Adapt your non-plugin init.vim
configuration to use Envy's module options.
By "non-plugin" here we mean specifically things that either don't depend on/configure any plugin, or that could depend on any one of several plugins (in which case, you should use Nix functionality to check which/whether any of those plugins are enabled and adapt the generated configuration appropriately).
Envy provides a wide array of options here, so some examples may be helpful:
{ config, lib, pkgs, ... }:
{
# Configuration items that should be done prior to any per-plugin configuration
prePluginConfig = ''
let mapleader = "\<Space>"
augroup vimrc
autocmd!
augroup END
set termguicolors
'';
# General configuration items that are appended to the end of the generated
# vimrc. You can use e.g. `lib.mkAfter` if you need something to go at the
# very end of the file.
extraConfig = ''
set incsearch
set hlsearch
set ignorecase
set smartcase
set number
set relativenumber
set autoindent
set shiftwidth=2
set softtabstop=2
set tabstop=2
set expandtab
" Use Ripgrep (rg) for search backend
let g:ackprg = '${pkgs.ripgrep}/bin/rg --vimgrep --smart-case --no-heading --max-filesize=4M'
set grepprg:${pkgs.ripgrep}/bin/rg\ --vimgrep\ --smart-case\ --no-heading\ --max-filesize=4M
nnoremap <Leader>o :exe ':silent !${pkgs.xdg-utils}/bin/xdg-open % &'<CR>
'';
# A list of packages whose executables should be added to the $PATH for
# neovim. These will *only* be added to neovim's path, not to the system or
# user profiles.
extraBinPackages = with pkgs; [
silver-searcher
xdg_utils # xdg-open
];
# See chapter 3
mergePlugins = true;
# `files` can be used to build a symlink tree of files and folders, which
# would typically consist of any extra/local contents of .config/nvim/ in a
# non-Nix neovim setup.
files = {
neosnippets.source = "/my/snippet/files/";
};
}
Enabling Plugins
You can enable both pre-existing Nix vim plugin derivations (e.g. from
nixpkgs), and vim plugins on github, both by using
pluginRegistry.<pluginName>.enable
.
There are several ways to specify the source for a plugin, depending on what you want:
{ config, lib, pkgs, ... }:
{
pluginRegistry = {
# In this case, the name 'ale' is automatically 'resolved' against
# pkgs.vimPlugins to select the plugin source
ale.enable = true;
# In this case, `source` is explicitly pointed to an existing Vim plugin
# derivation.
"denite.nvim" = {
enable = true;
source = pkgs.vimPlugins.denite-nvim;
};
# In this case, the name fails to resolve against pkgs.vimPlugins, so
# `source` is automatically inferred from the `name`, on the assumption
# that it is a vim-plug-compatible 'shortname', which will be used to
# dynamically construct a derivation from a Vim plugin sourced from
# https://github.com/Shados/vim-session (see chapter 3).
"Shados/vim-session".enable = true;
vim-buffet = {
enable = true;
# In this case, we again are using a shortname for the source, but we set
# it explicitly.
source = "bagrat/vim-buffet";
# Additionally, we specify the exact commit we want to pin and use for the git source.
# Generally you are better off relying on the separate JSON pin files to
# pin to a specific commit, but in this case the version after this
# commit has breaking changes, which would mean the configuration of the
# plugin would also have to change, meaning that the commit information
# is more an element of configuration than of state. 'branch' and 'tag'
# are also supported for specifying what to fetch.
commit = "044f2954a5e49aea8625973de68dda8750f1c42d";
};
localPlugin = {
enable = true;
# In this case, Envy will dynamically construct a derivation using the
# given Nix store path as the source.
source = /some/local/path/or/store/path;
};
inDevPlugin = {
enable = true;
# Here we instead instruct Envy to have Vim load the plugin from a local
# filesystem path at run-time, rather than bundling it into the Nix
# store. This is useful for doing plugin development, or if you otherwise
# want to use a plugin outside of the Nix store, while still allowing you
# to leverage Envy's configuration and dependency
# specification/resolution mechanisms.
dir = "/a/local/path/string";
};
};
}
Specifying Dependencies
Envy allows for specifying a wide variety of dependency types:
{ config, lib, pkgs, ... }:
{
pluginRegistry = {
# Inter-plugin dependencies; the items should preferably be the names of
# `pluginRegistry` or `vim.vimPlugins` items, but can alternatively be Vim
# plugin derivations.
neosnippet-snippets.dependencies = [ "neosnippet-vim" ];
# Specifies that a plugin needs external executables from the given
# packages made available in neovim's $PATH.
ale.binDeps = with pkgs; [
bash
shellcheck
shfmt
];
# Ensures that the specified Lua modules will be made available in
# neovim's LUA_PATH/LUA_CPATH, meaning that the main neovim process can
# load them for in-process Lua plugins and scripts to use.
"Shados/precog.nvim".luaDeps = ps: with ps; [
luafilesystem
];
# Flags a plugin as being a 'remote' plugin requiring a plugin host for a
# specific language (here, Python 3).
denite-nvim.remote.python3 = true;
# Pulls in plugin-host-language dependencies.
# Automatically implies `remote.python2 = true;`.
aPythonPlugin.remote.python2Deps = ps: with ps; [
requests
];
};
}
Inter-plugin dependencies also determine the order in which Vim plugins are loaded at Vim run-time (by vim-plug).
There are additionally two "soft" dependency options (before
and after
,
both of which take lists of plugin names only), that change how plugins are
ordered if both are enabled, but does not cause the "dependency" to be enabled
if the "dependent" plugin is, e.g.:
{ config, lib, pkgs, ... }:
{
pluginRegistry = {
# vim-devicons needs to be loaded after these plugins, if they
# are being used, as per its installation guide
vim-devicons.after = [
"nerdtree" "vim-airline" "ctrlp-vim" "powerline/powerline" "denite-nvim"
"unite-vim" "lightline-vim" "vim-startify" "vimfiler" "vim-flagship"
];
};
}
It should be noted that lazy-loaded plugins don't fully respect ordering options, and don't trigger lazy-loading of dependencies. Either ensure dependencies aren't also being lazy-loaded, or put them behind the same lazy-load triggers as their dependents.
Plugin Configuration
There is a per-plugin version of the extraConfig
option, under
pluginRegistry.<pluginName>.extraConfig
. These are inserted into the
generated nvimrc after the prePluginConfig
, before the top-level
extraConfig
, and in the same order plugins are loaded (that is, based on
dependencies and explicit ordering information).


void MemDowngradeExclLock( MemHandle mh); /* handle of affected block */
An application that has an exclusive lock on a block may downgrade it to a shared lock with this routine. It does not otherwise affect the block.
Include: heap.h
void MemFree( MemHandle mh); /* handle of block to be freed */
This routine frees a global memory block. The block can be locked or unlocked.
Include: heap.h
Warnings: The routine does not care whether other threads have locked the block. If you try to free a bad handle, routine may fatal-error.
word MemGetInfo( /* return value depends on flag passed */ MemHandle mh, /* Handle of block to get info about */ MemGetInfoType info); /* Type of information to get */
MemGetInfo()
is a general-purpose routine for getting information about a global memory block. It gets the information by looking in the block's handle table entry; it does not need to access the actual block. It returns a single word of data; the meaning of that word depends on the value of the
MemGetInfoType
variable passed. The following types are available:
HeapFlags
record for the block. The lower byte is the number of locks currently on the block.
MemDeref()
is preferable.
HM_otherInfo
word. This word is used in different ways for different types of handles.Include: heap.h
Warnings: If the handle is not a global memory block handle, results are unpredictable (the routine will read inappropriate data from the handle table entry).
See Also: MemDeref()
,
MemModifyFlags()
,
MemModifyOtherInfo()
,
HandleModifyOwner()
.
void MemIncRefCount( MemHandle mh); /* handle of affected block */
This routine increments the reference count of a global memory block (the reference count is stored in HM
_otherInfo
).
Warnings: This routine assumes that a reference count is stored in HM
_otherInfo
. You may only use this routine if the block has had a reference count set up with
MemInitRefCount()
.
Include: heap.h
void MemInitRefCount( MemHandle mh, /* handle of affected block */ word count); /* initial reference count */
This routine sets up a reference count for the specified global memory block. The passed count is stored in the HM
_otherInfo
field of the block's handle-table entry.
Warnings: This routine overwrites the HM
_otherInfo
field. Since the semaphore routines (
HandleP()
and
HandleV()
and the routines which use them) use this field, you cannot use both the semaphore routines and the reference count routines on the same block.
Include: heap.h

- In 1997, 72% of the business was also owned by Netscape. But Internet Explorer 4.0 was released in October 1997 and browser war waves were modified. It pursued the released specifications of W3C faster and more loyally than Netscape Navigator 4.0. In browser battles, Microsoft has two key advantages. One was a matter of resources: Netscape began with almost 90% market share and a great deal of public goodwill, but it became financially fragile as a relatively small business which produced most of its profits from what was essentially one commodity. Gross sales of Netscape have never matched the cash-on-the-hand earnings of Microsoft.
- The other, most significant, advantage was that Microsoft Windows has an industry lock that could be used to take over IE. IE arrived with every Windows clone and thus Microsoft somehow managed to grow market share even though IE's prior versions were marginally less than Netscape's browser. And IE remained free because Windows' huge sales helped to fund its development and promotion, leading to drastic updates to Netscape so close it could not be downloaded and installed.
