What is it about South Mimms? Further revelations from Strange Cults And Secret Societies Of Modern London by Elliott O'Donnell (1934):
“On All Hallows E'en certain members of the [Ghost] Circle were invited to meet, at eleven at night, in secrecy, at cross-roads not far from South Mimms. All turned up, the founder, as usual, arriving first, and on the neighbouring clock striking midnight, they were surprised to see a herd of pigs trotting down the road towards them, road and pigs gleaming white in the moonbeams. Never had any of the members of the Ghost Circle seen such pigs! They seemed to be positively gigantic, but thin. On they came, perfectly noiselessly, and on arriving at the cross-roads, they passed through a gateway into a field, leaving in their wake a current of icy air. There was something so strange and eerie about them that several members of the Ghost Circle, overcoming a certain reluctance, ran to the gate to have another look at them. The field, which afforded no cover of any kind, was very large, and it was empty, save for cattle. The pigs had inexplicably vanished.
“The members of the Circle learned subsequently that the cross-roads were known to be haunted by a herd of phantom pigs, but only on All Hallows E'en.”
I think at the end of this month the Hooting Yard Phantom Pig Spotting Club should convene at that cross-roads in South Mimms. Be there or be square, as the hepcats used to say, half a century ago, daddy-o!

Dogs are pretty cool animals with four legs and a tail. The thing about dogs is people actually own them as pets. I feel like if you are alive and over the age of 2, you have probably seen one before.

Hi. I'm Andrew. I'm in CS at Cornell. I think in computer science and philosophy. I pass the Turing test most of the time. I'm excited to share with you my adventures in artificial intelligence, games and computer music.
So I'm starting this new blog format. To start off, on Mondays and Fridays, I'll spotlight one of my previous projects. Here's a preview:
- The Land of Stuff: online role-playing game.
- Sound Transfer: transfer data between computers with microphone and speaker.
- Author: a text classifier that figures out who wrote an essay or book.
This site is made using my own static site generator, nanosite. The vision is for making website content to be as intuitive and beautiful as possible, through simple tools and workflow. Right now it is a baby.
Also, here's QuickSort in OCaml!
let rec sort = function
| [] -> []
| h::t -> let pivot = h in
let (left, right) = List.partition ((>) pivot) t in
(sort left) @ [pivot] @ (sort right)
Stay tuned for more.

I have tried in the past to contact, I am sure that you are aware of the
situation with Kreis and Spring, I was actually attempting contact a few months
ago. Here's a little rundown....
Spring has admitted to federal involvement, you may already be
aware...
Kreis "dismissed the organization" like a pussy, I understand why, but it
was good news, even though he still has the website up and running.... Both have
forfeited leadership.....
We, the Organization that I am attached with, were going to place a new
Aryan Nations website up this coming Monday, since we were unable to contact,
however, if we can work something out, we can merge operations, and strengthen
Butler's legacy rather than to fracture it....

In this setup we iteratively generate RDF from 11 air quality JSON reports.
The syntax of the ITERATOR clause is the following:
ITERATOR <iterator>(args) AS ?var ITERATOR <iterator>(args) AS ?var_1 ?var_2 ?var_3 ... ?var_n
Where <iterator> is the IRI of the SPARQL-Generate iterator function, which is similar to a SPARQL 1.1 Function, except it returns a list of RDF Terms instead of just one. ?var will be bound to every RDF Term in the list returned by the evaluation of the iterator function over the arguments args.
Iterator function iter:for
is documented at its URI.

Instinct (1999)
Director: Jon Turtletaub Cast: Anthony Hopkins, Cuba Gooding Jr., Donald Sutherland, Maura Tierney, George Dzundza Screenplay: Gerald Di Pego (based on the novel by Daniel Quinn) Producers: Barbara Boyle, Michael Taylor Runtime: US Distribution: Buena Vista Pictures Rated R: Violence
Copyright 1999 Nathaniel R. Atcheson
You know, I never really wondered what the Tarzan films would have been like had Tarzan been an old man. While watching Instinct, I couldn't help but acknowledge the way the film carelessly rehashes the well-explored themes of those earlier movies. Even beside the Tarzan comparison, Instinct just isn't a very good film. It's painfully idealistic, manipulative, and silly.  But I can recognize Instinct for what it is beyond my subjective admiration for the actors involved. I can also recognize reasons for wanting to make Instinct, and it's pretty clear that this could have been a good film with a massive script overhaul and a director less interested in imitating movies like Patch Adams.
Things start off in the predictable way, as director Jon Turtletaub introduces us to our hero, Theo Caulder (Cuba Gooding, Jr.), an ambitious, young psychiatrist under the supervision of an experienced, old psychiatrist (Donald Sutherland). Caulder soon finds himself involved in the case of his life, the one he thinks will make him famous. The subject is Ethan Powell (Hopkins), an anthropologist who has been living among gorillas in Africa for the past two years. Powell has been charged with the brutal murders of several men in Africa, and it's now Caulder's job to find out of he's mentally competent enough to stand trial. Through a series of short sessions, Caulder tries to put together the complex psyche of Powell.
Even though it really is an old man version of Tarzan, much of this central idea is rather interesting. As I said, Hopkins is captivating for every second he's on screen; he has a way of convincing us that he's not acting, that he's actually a man who has just spent two years of his life living with a family of wild gorillas. The character himself isn't very interesting -- he's just an anthropologist who really likes gorillas -- but Hopkins makes him interesting with subtleties both in speech and action. Gooding Jr. does strong work opposite Hopkins, playing Caulder as an intelligent and flawed individual. The screenplay, written by Gerald Di Pego and "suggested by" a novel by Daniel Quinn, gives us no background information on Caulder, but that seems to be the point (he has no time for friends because he's obsessed with his work). Nonetheless, these two actors are essentially the entire list of things that are good about Instinct.
Unfortunately, filmmaking this inept can mangle the effect of even the best acting. Turtletaub and Di Pego are both guilty of Instinct's artistic failure, for they work together to make the dumbest, most cliche-ridden environment in which their characters are to live, and they do so by means of brainless subplots. First, we have the prison warden subplot. The prison warden is evil and wants to stop Caulder's progress at any cost; if this means taking Caulder off the Powell case, then that's fine. There's also the prison guard subplot. The prison guard is played by John Ashton; the prison guard seems to enjoy mercilessly beating upon the psychotics under his supervision, and he's instrumental in helping the story along to its obvious conclusion. Then there's the daughter subplot, in which Maura Tierney (playing the daughter) must look very upset a lot of the time; after all, she is the daughter of a deranged man.
If some of this stuff sounds familiar, that's because they're all devices that have been used and reused in countless other films. The evil doctor in Patch Adams is not unlike the evil warden here. The offensive caricatures of mental patients lack the depth that the similar portrayals in One Flew Over the Cuckoo's Nest had. Ashton's evil prison guard pales in comparison to Clancy Brown's in The Shawshank Redemption. Hopkins' performance will undoubtedly remind audiences of his turn in The Silence of the Lambs. And then there's the whole Tarzan thing, which is more than a little bit obvious through the entire film.
Perhaps what irritates me most about Instinct is the half-hearted attempt at philosophical depth. The message Powell brings back from the wild is not a subtle one: he thinks that humans are "takers," that they expand and kill and that we should all just live like gorillas. I can sympathize with that, but only when it's in a compelling film.  What does any of this have to do with a man who has just spent two years of his life with gorillas? If all the subplots of Instinct had been left on the cutting room floor, we would have had a thirty-minute movie far superior to the two-hour one that I watched today. If the central idea had been developed beyond the Old Man Tarzan premise, then we would really have had something interesting -- a movie that doesn't rely on the strength of its actors.

Rigging tip - Hanging piece of equipment
by Pierrick Picautp2design writes:
Hanging pieces on a character are pretty common. It can be long clothes, hairs, chains.... Whatever fit your design.
Whenever you are using hand keyed animation, it can be pretty handy to properly set the pivot point mechanism of these parts to avoid counter animation. Here is a short tip video where I will show you how I rig character hanging pieces for my animations.
Hope you will like it,

Frequently Asked Questions
Where are all the docs?
As Tellu is one man's project, work is focused mainly on coding new features and bugfixing. I will write some user guides when I have time for that, but unfortunately for now there is no any documentation except what you can find in these pages.
What does word Tellu mean?
Tellu is a finnish girl's nickname, so it is not a contortion from english word Tell'u or Tell you. Also in Peanuts comic, Lucy van Pelt is translated in finnish as Tellu.

Procedural knowledge can be presented as plan-trees, protocols (modal message exchanges), or as sequences of instructions. It is not always obvious which is the "best" representation. We examine the alternatives for a simple case.
Consider the case where we want to represent the process knowledge involved when we back a cake. Typically, the first instruction in the
We can represent such knowledge using a plan tree.
Goal: Bake a cake perrecipe .Preconditions: . Oven is preheated tooven-temperature specified inrecipe . . Cakebatter , prepared perrecipe , is in greased cake-pan.Action: .Arm: Place cake-pan in oven for time given inrecipe .Goal: Cakebatter , prepared perrecipe , is in greased cake-pan.Preconditions: .Cake-pan is greased. .Batter is prepared perrecipe .Action: .Arm: Pourbatter from mixing-bowl into cake-pan.Goal: Oven is preheated tooven-temperature specified inrecipe .Preconditions: .Oven heat is on. .Oven thermostat is set to oven-temperature .Action: . Oven: Signal whenoven-temperature settles.Goal: Batter is prepared perrecipe .Preconditions: .Cake .ingredients required byrecipe are assembled on mixing-counter.mixing-equipment clean and ready. Action: . Mixer: Blendingredients , givingbatter .
In the example above, the highlighted statements
indicate goals that have no preconditions
and the subgoal can be achieved by executing an equivalent action statement.
We could make this more concise by adapting the convention
that preconditions can be stated as actions.
(Actions are indicated by the role-prefix pattern: <role>: <action>.
)
With that convention, the goal frames above become . . .
Goal: Bake a cake perrecipe .Preconditions: .. Cake Oven: Preheat tooven-temperature specified inrecipe .batter , prepared perrecipe , is in greased cake-pan.Action: .Arm: Place cake-pan in oven for time given inrecipe .Goal: Cakebatter , prepared perrecipe , is in greased cake-pan.Preconditions: .. Helper: Grease cake-pan.Batter is prepared perrecipe .Action: .Arm: Pourbatter from mixing-bowl into cake-pan.Goal: Oven is preheated tooven-temperature specified inrecipe .Preconditions: .Oven: Turn heat on. .Oven: Set thermostat to oven-temperature .Action: . Oven: Signal whenoven-temperature settles.Goal: Batter is prepared perrecipe .Preconditions: .Mixer: Assemble .ingredients required byrecipe .Mixer: Stage mixing-equipment. Action: . Mixer: Blendingredients , givingbatter .
I perceive three problems with this kind of condensation:
1. It may encourage premature pruning of the plan tree -- enabling bad habits.
2. It mixes assertion statements with action statements -- reducing readability.
3.
We can also represent this process knowledge as a sequence of instructions. But instructions in a sequence are implicitly blocking. By representing the process in a sequence, we obscure the information that some things can happen in parallel. Of course, an experienced human cook would know this and compensate. But, what if our agent is a robot rather than a human cook?
Role: Baker. Action: Bake a cake perrecipe . .Oven: Preheat tooven-temperature perrecipe . .Helper: Grease cake-pan. .Mixer: Preparebatter perrecipe . .Arm: Pourbatter intocake-pan . .Arm: Placecake-pan inoven for time given inrecipe . (Example does not include stages beyond baking the cake.)
We could use some convention to indicate "futures" . . .
In the following, the "giving . . ." clause indicates a future.
The compiler can furnish the needed semaphores for coordination.
Role: Baker. Action: Bake a cake perrecipe . .Oven: Preheat tooven-temperature perrecipe giving preheated-oven. .Helper: Grease cake-pan giving greased-cake-pan. .Mixer: Mix ingredients perrecipe givingbatter . .Arm: Pourbatter intocake-pan . .Arm: Placecake-pan inoven for time given inrecipe giving baked-cake-in-pan. (Example does not include stages beyond baking the cake.)
The compiler could also analyze the statements (without the "giving" clauses) to infer that instructions delegated to different roles may be performed in parallel; but, instructions delegated to the same role must be performed in sequence. The IDE might also analyze noun usage to provide hints about where giving clauses might be appropriate.
However, I regard such ideas as "work-arounds" that pollute the original semantic intent. Such ideas add still more ways to express the same process structure. Having more than one way to express a process makes a program harder to maintain because the maintenance programmer may have to look in more than one place to find the relevant code. It also enables a situation where multiple programmers working in a major codebase may create confusion and entropy with a mix of programming styles and structures.
Imagine a future where we script interactions between users and VR avatars. The notation below resembles that for a stage play. "U:" is shorthand for "User:" and shows patterns indicating user requests. "S:" is shorthand for "System:" and shows the system response. The system response may include setting plans in motion. Where an avatar may be available, avatar gestures may be indicated with annotation.
Perhaps "Q:" and "A:" would be more evocative of request-response.
Real-life dialogs are context-sensitive. The dialog partner remembers what has been said before and responses are prioritized to match the most recently "pushed" context.
Context: Guest at reception. [Gesture: Watch guest.] U: Hello. U: Hi. S: Hello. Welcome to Club Mech. [Gesture: Smile.] Context: Member at reception. U: Hello. U: Hi. S: Hello [member name]. How may I help you? [Gesture: Expecting answer.] . Push context 'Member request'. Context: Member request. U: * account *. S: Here is your current account statement. All charges are up-to-date. Payments are posted when they are received. . Show 'Member Account' view.
Many user interfaces are based on paper document conventions. In the frame below we use show a view that uses a wiki-like mark-up to indicate data slots and font emphasis.
View: Member Account. !! Account Statement for member: [member`s name] as of: [clock`s date-time] Prior period balance: [prior-period`s balance] Payments received: [prior-period`s payment-total] Current period balance: [current-period`s balance] !!! Current Period Charges . Table of member`s outstanding-charges: | date-and-time | description | price | . Subtotal price.
In traditional programming, the programmer writes instruction sequences to be interpreted by a computer (a programmable calculator). The speaker (sender) is the programmer. The listener (receiver) is the computer. User interfaces involve the programmer instructing the computer about how to exchange messages with a human user. But the point-of-view still tends to be that of the programmer. "When user says this, do that."
But in an enterprise context or in the internet of things (IoT), we may need to rethink the nature of programs. Instead of programmers speaking to computers, the more common mode is robots speaking to robots. The new point-of-view for the programmer is to write the scripts for those robot-to-robot communications. This requires changing the programmers point-of-view to that of one of the robot actors.

The -a flag causes pvmt to print out all block handles, not just those that have been allocated. The other two types of block handles are "assigned" (meaning they're available for use, but currently are tracking unused space in the file) and "unassigned" (they're available for use).
-
The -s indicates the final argument is a segment, not a file handle. This is used only if you're inside the VM subsystem of the kernel.
-
The -c flag requests a count of the different types of blocks at the end of the printout.
-
The blocks are printed in a table with the following columns:
-
han
- VM block handle (in hex)
-
flags
D if the block is dirty,
-
C if the block is clean,
- if the block is non-resident,
L if the block is LMem,
B if the block has a backup,
P if the preserve handle bit is set for the block,
! if the block is locked
-
memhan
- Associated memory handle. Followed by "(d)" if the memory for the block was discarded but the handle retained. Followed by (s) if the memory has been swapped out.
-
block type
- The type of block:
-
VMBT_USED a normal in-use block,
-
VMBT_DUP an in-use block that has been backed up or allocated since the last call to
VMSave()
-
VMBT_BACKUP a place-holder to keep track of the previous version of a VMBT_DUP block. The uid is the VM block handle to which the file space used to belong.
-
VMBT_ZOMBIE a block that has been freed since the last
VMSave()
. The handle is preserved in case of a
VMRevert()
(a VMBT_BACKUP block retains the file space).
-
uid
- The "used ID" bound to the block.
-
size
- Number of bytes allocated for the block in the file.
-
pos
- The position of those bytes in the file.
See Also: pgs.
pvsize
pvsize [<object>]
Examples:
-
"pvsize"
- print the dimensions of the visual object at *ds:si.
Print out the dimensions of a visual object.
-
The object argument is the address to the object to print out. It defaults to *ds:si and is optional. The `-i' flag for an implied grab may be used.
-
The special object flags may be used to specify <object>. For a list of these flags, see pobject.
pwd
pwd
Examples: "pwd"
Prints the current working directory for the current thread.
See Also: dirs,
stdpaths.
quit
quit [<options>]
Examples:
-
"quit cont"
- continue GEOS and quit swat
-
"quit det"
- detach from the PC and quit swat.
Stop the debugger and exit.
-
The <option> argument may be one of the following:
continue
: continue GEOS and exit swat;
leave
: keep GEOS stopped and exit swat.
-
Anything else causes swat to detach and exit.
See Also: detach.
read-char
read-char [<echo>]
Examples:
-
"read-char 0"
-
Read a single character from the user and don't echo it.
Reads a character from the user.
If <echo> is non-zero or absent, the character typed will be echoed.
See Also: read-line.
read-line
read-line [<isTcl> [<initial input> [<special chars>]]]
Examples:
-
"read-line"
- reads a single line of text.
-
"read-line 1"
- reads a Tcl command.
-
"read-line 1 {go}"
-
reads a Tcl command that starts with "go "
-
"read-line 1 {} {\e\4}"
-
reads a Tcl command, considering escape and control-d cause for immediate return, regardless of whether braces and brackets are balanced
Reads a single line of input from the user. If optional argument is non-zero, the line is interpreted as a Tcl command and will not be returned until all braces/brackets are balanced. The final newline is stripped. Optional second argument is input to be placed in the buffer first. This input must also be on-screen following the prompt, else it will be lost.
-
If <isTcl> is non-zero, the input may span multiple lines, as read-line will not return until all braces and brackets are properly balanced, according to the rules of Tcl. This behavior may be overridden by the <special chars> argument.
-
If <initial input> is given and non-empty, it is taken to be the initial contents of the input line and may be edited by the user just as if s/he had typed it in. The string is not automatically displayed; that is up to the caller.
-
<special chars> is an optional string of characters that will cause this routine to return immediately. The character that caused the immediate return is left as the last character of the string returned. You may use standard backslash escapes to specify the characters. This will return even if the user is entering a multi-line Tcl command whose braces and brackets are not yet balanced.
-
The user's input is returned as a single string with the final newline stripped off.

Step Functions Data Science SDK for building machine learning (ML) workflows and pipelines on AWS. This package utilises paws
to make a connection to AWS
.
Cran Version
# TBC
Dev Version
remotes::install_github("DyfanJones/aws-step-functions-data-science-sdk-r")
Note this example is taken from: https://github.com/aws/aws-step-functions-data-science-sdk-python
You create steps using the SDK, and chain them together into sequential workflows. Then, you can create those workflows in AWS Step Functions and execute them in Step Functions directly from your R code. For example, the following is how you define a pass step.
library(stepfunctions)
start_pass_state = Pass$new(
state_id="MyPassState"
)
The following is how you define a wait step.
wait_state = Wait$new(
state_id="Wait for 3 seconds",
seconds=3
)
The following example shows how to define a Lambda step, and then defines a Retry and a Catch.
lambda_state = LambdaStep$new(
state_id="Convert HelloWorld to Base64",
parameters=list(
"FunctionName"="MyLambda", #replace with the name of your function
"Payload"=list(
"input"="HelloWorld")
)
)
lambda_state$add_retry(Retry$new(
error_equals=list("States.TaskFailed"),
interval_seconds=15,
max_attempts=2,
backoff_rate=4.0
))
lambda_state$add_catch(Catch$new(
error_equals=list("States.TaskFailed"),
next_step=Fail$new("LambdaTaskFailed")
))
After you define these steps, chain them together into a logical sequence.
workflow_definition=Chain$new(list(start_pass_state, wait_state, lambda_state))
Once the steps are chained together, you can define the workflow definition.
# change execution role to your execution role
stepfunctions_execution_role="dummy-role"
workflow = Workflow$new(
name="MyWorkflow_v1234",
definition=workflow_definition,
role=stepfunctions_execution_role
)
The following generates a graphical representation of your workflow. Please note that visualization currently only works in Jupyter notebooks. Visualization is not available in JupyterLab.
workflow$render_graph()
NOTE: Currently graphs can only render in jupyter notebook. Rendering graphs in Rstudio is on the todo list :)
The following renders the JSON of the Amazon States Language definition of the workflow you created.
workflow$definition$to_json(pretty=TRUE)

Logging is one of the most effective debugging and troubleshooting techniques although some engineers claim that it is not that helpful or it will slow the application. My experience with it is always positive.
I use log4net from the Apache Software Foundation as my logging layer for .Net applications. log4net is available here as a zip archive.
Download log4net from here.
Open Visual Studio and create a new Console application project.
Add to the project a reference to the \bin\net\2.0\release\log4net.dll assembly in the log4net distribution.
Modify your Main() method like so:
1: using System;
2: namespace ConsoleApplication1
3: {
4: class Program
5: {
6: static void Main(string[] args)
7: {
8: log4net.Config.BasicConfigurator.Configure();
9: log4net.ILog log = log4net.LogManager.GetLogger(typeof(Program));
10:
11: log.Debug(“Hello World!”);
12: log.Info(“Just info.”);
13: log.Warn(“careful this is a warning.”);
14: log.Error(“Bad news: Error occurred.”);
15: log.Fatal(“Here is the end.”);
16: }
17: }
18: }
Compile and run the application, and you’ll see output to the console like so:
In the Hello World example we configured log4net in the most basic way possible just to get started. Using the BasicConfigurator (line 8) will cause log4net to output log entries to the console using the default layout. Line 9 requests a logger from the LogManager object. Logger objects implement the ILog interface, which is what your application will use to instrument itself and percolate log entries.
Lines 11-15 use the logger to log a few statements with various severity levels. log4net defines 5 such levels:
In the previous example we used the BasicConfigurator. If we just changed the configurator to XmlConfigurator and run the application you will get the following output error:
log4net:ERROR XmlConfigurator: Failed to find configuration section ’log4net’ in
the application’s .config file. Check your .config file for the <log4net> and <
configSections> elements. The configuration section should look like:

This error resulted because XMLConfigurator relies on an XML document to supply configuration for log4net. The static Configure method have 10 overloads to accept the XML configuration from a file, stream, URI, or an XmlElement object. The parameterless overload of the method we used instructs log4net to load the XML from the application’s configuration file. Since our application doesn’t contain any configuration files (till now), the Configure method returned the above error.
To overcome this error, add Application Configuration File to the project and add the following XML configuration:
1: <configuration>
2: <configSections>
3:

4: </configSections>
5:
6: <log4net>
7: <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
8: <layout type="log4net.Layout.SimpleLayout" />
9: </appender>
10:
11: <root>
12: <level value="ALL" />
13: <appender-ref ref="ConsoleAppender" />
14: </root>
15: </log4net>
16: </configuration>
Compile and run, you will see output changed to be like so:
In addition to the Configure method, XmlConfigurator offers a static ConfigureAndWatch() method that accepts a FileInfo reference. ConfigureAndWatch() will monitor the XML configuration file and reconfigure log4net when a change is detected in this file. This allows you to alter logging behavior while the application is running to fit your current troubleshooting requirements.
If we look at the application configurations file, the declaration of the log4net configuration section on line 3 is mandatory. The log4net configurations section [lines 6-15] consists of two sub-sections: appender and root. log4net appender is the place where your application log entries end up (Console in our example). We will talk about appenders later. The root logger controls the general behavior of log4net. In this example, the root logger is told to send everything to the console appender.
In the previous examples we were logging all types of severity levels. If you want to filter the logging output to fit your application’s life current phase (development, production) or troubleshooting needs, you can just change the value of <level /> XML element in your app.config. The level value instructs the logger of the minimum level at which log entries should be processed. It can be: ALL (everything is enabled), DEBUG (identical to ALL), INFO (everything except DEBUG), WARN (warn, Error, and Fatal), ERROR (Error and Fatal), FATAL (only Fatal), OFF (logging is disabled).
Before going further with log4net, let’s talk about its structure. log4net built using the layered approach, with four main components inside of the framework. These are Logger, Repository, Appender, and Layout.
The Logger is the main component with which your application interacts. It is also the component that generates the log messages.
The Repository is responsible for maintaining the logical organization
of loggers inside the framework. Currently log4net only supported the
hierarchical organization through log4net.Repository.Hierarchy
namespace. If you want to extend log4net to implement new organization,
you have to implement the log4net.Repository.ILoggerRepository
interface or inherit class
log4net.Repository.LoggerRepositorySkeleton
. Almost all developers do
not use any of these Repository
classes; they only use the
LogManager
class to automatically manage the repositories and the
loggers.
The Appender is used to define the output medium that log statements
will go for it at the end of the day. As the name suggests, these
components append themselves to the Logger component and relay the
output to an output stream. You can append multiple appenders to a
single logger. There are several appenders provided by the log4net
framework. If you want to write your own appender, you can start by
inheriting thelog4net.Appender.AppenderSkeleton
class, which works as
an adapter between your class and the IAppender
interface. You can use
Appender Filters to filter logging events sent from appenders before
processing it.
The Layout component is used to display the final formatted output to
the user. The output can be shown in multiple formats, depending upon
the layout we are using. It can be linear or an XML file. The layout
component works with an appender. There is a list of different layouts
in the API documentation. You cannot use multiple layouts with an
appender. To create your own layout, you need to inherit
thelog4net.Layout.LayoutSkeleton
class, which implements the ILayout
interface.
A n appender is an object that persists your log messages someplace. In the table below a list of the appenders provided by log4net.
Appender
Description
AdoNetAppender
Appender that logs to a database.
AnsiColorTerminalAppender
Appends logging events to the terminal using ANSI color escape sequences.
AspNetTraceAppender
Appends log events to the ASP.NET TraceContext system.
BufferingForwardingAppender
Buffers events and then forwards them to attached appenders.
ColoredConsoleAppender
Appends logging events to the console colored.
ConsoleAppender
Appends logging events to the console.
DebugAppender
Appends log events to the Debug system.
EventLogAppender
Writes events to the system event log.
ForwardingAppender
This appender forwards logging events to attached appenders.
FileAppender
Appends logging events to a file.
LocalSyslogAppender
Logs events to a local syslog service.
MemoryAppender
Stores logging events in an array.
NetSendAppender
Logs entries by sending network messages using the NetMessageBufferSend native function.
OutputDebugStringAppender
Appends log events to the OutputDebugString system.
RemoteSyslogAppender
Logs events to a remote syslog daemon.
RemotingAppender
Delivers logging events to a remote logging sink.
RollingFileAppender
Appender that rolls log files based on size or date or both.
SmtpAppender
Send an e-mail when a specific logging event occurs, typically on errors or fatal errors.
SmtpPickupDirAppender
Send an email when a specific logging event occurs, typically on errors or fatal errors. Rather than sending via smtp it writes a file that another service, such as the IIS SMTP agent, can use to manage sending the messages.
TelnetAppender
Appender that allows clients to connect via Telnet to receive log messages.
TraceAppender
Appends log events to the Trace system.
UdpAppender
Sends logging events as connectionless UDP datagrams to a remote host or multicast using the UdpClient class.
These appenders write log messages to files. A typical configuration for the FileAppender might l ook like this:
1: <appender name="FileAppender" type="log4net.Appender.FileAppender">
2: <file value="log.txt" />
3: <appendToFile value="true" />
4: <encoding value="utf-8" />
5: <layout type="log4net.Layout.SimpleLayout" />
6: </appender>
Configuration attributes and its description are:
Keep in mind that the log file managed by FileAppender will be allowed to grow without bounds. The RollingFileAppender provides basic log file management, configurable size- or date-boxing of the log file, and limited rolling backups of the log file.
1: <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
2: <file value="log-file.txt" />
3: <appendToFile value="true" />
4: <rollingStyle value="Size" />
5: <maxSizeRollBackups value="10" />
6: <maximumFileSize value="1MB" />
7: <staticLogFileName value="true" />
8: <layout type="log4net.Layout.SimpleLayout" />
9: </appender>
Configuration attributes and its description are:
rollingStyle: this controls how log files are “rolled,” and can be one of the following values:
maximumFileSize: the size cap on the log file. This is an expression of size in the form of “#(KB|MB|GB)". For instance, “100KB” or “10MB”;
maxSizeRollBackups: the maximum number of rolled log file backups to maintain when rollingStyle is SIZE; when rollingStyle is COMPOSITE, this indicates the maximum number of roll-offs maintained per day; this property has no effect when rollingStyle is ONCE or DATE;
datePattern: the date pattern used to roll files based on date. The value of this parameter needs to adhere to the format used by the SimpleDateFormatter class;
staticLogFileName: a bit of a misnomer - when true this setting indicates whether log4net should actively write logs to the configured file (log-file.txt in our example configuration) and maintain rolling backups by copy. When false, this setting indicates that log4net will actively log to the latest roll-off file (e.g., log-file1.txt, log-file2.txt, log-file3.txt, etc);
countDirection: indicates how roll-off file numbering is managed. When this parameter is >= 0, the newest log file will have the largest number; e.g., log-file.txt.5 will be newer than log-file.txt.4. When countDirection < 0, the newest log file will have the lowest number; e.g., log-file.txt.1 will be newer than log-file.txt.2. If unspecified, countDirection defaults to (-1);
Keep in mind that when using a file appender, the user running the logging process must have rights to create and/or modify the log file in order for log messages to be written properly. In addition, log4net will create the log file if it does not exist, but it will not create directories in the log file path that do not already exist. If log4net encounters a problem initializing the file appender (e.g., it cannot create the log file for security reasons), the log file will not be written but your application will continue to execute normally.
You can use multiple appenders by specifying each appender you need under the root logger.
A layout is just a template for your log messages. Layouts are specified per-appender, and you can specify only one layout for an appender:
1: <appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
2: <layout type="log4n
et.Layout.SimpleLayout" />
3: </appender>
The PatternLayout allows you to specify a printf-style template for your log entries using a “conversion pattern,” and gives you the opportunity to decorate each entry with some valuable instance data. For instance, this configuration:
1: <appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
2: <layout type="log4net.Layout.PatternLayout">
3: <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
4: </layout>
5: </appender>
produces a log that appears like so:
The conversion pattern string can include literal text and the following format expressions:
expression
value
%appdomain
the friendly name of the appdomain from which the log entry was made
%date
the local datetime when the log entry was made
%exception
a formatted form of t he exception object in the log entry, if the entry contains an exception; otherwise, this format expression adds nothing to the log entry
%file
the file name from which the log entry was made; note that using %file has a significant performance impact and I don’t recommend using it
%identity
the user name of the active user logging the entry; this one is less reliable than %username; note that using %identity has a significant performance impact and I don’t recommend using it
%level
the severity level of the log entry (DEBUG,INFO, etc)
%line
the source code line number from which the log entry was made; slow
%location
some rudimentary call stack information, including file name and line number at which the log entry was made; using
%logger
the name of the logger making the entry; more on this in a bit
%method
the name of the method in which the log entry was made; also slow
%message
the log message itself (don’t forget this part!)
%newline
the value of Environment.NewLine
%timestamp
the milliseconds between the start of the application and the time the log entry was made
%type
the full typename of the object from which the log entry was made
%username
the Windows identity of user making the log entry; slow
%utcdate
the UTC datetime when the log entry was made
%%
a percent sign (%)
A common usage of the %logger expression is to identify the source class in the log entries. Give the class name to the logger like:
private static log4net.ILog Log = log4net.LogManager.GetLogger( System.Reflection.MethodBase.GetCurrentMethod().DeclaringType );
and the output will be something like:
ConsoleApplication1.Program [INFO]- this is an info message
Using this technique can help you control logging concerns of your objects. For example, add a new class “MyClass” to your ConsoleApplication and use the above approach in declaring your loggers. Add the following after the <root> section in your app.config :
1: <logger name="ConsoleApplication1">
2: <level value="ALL" />
3: <appender-ref ref="FileAppender" />
4: </logger>
5: <logger name="ConsoleApplication1.Program">
6: <level value="ALL" />
7: <appender-ref ref="ConsoleAppender" />
8: </logger>
9: <logger name="ConsoleApplication1.MyClass">
10: <level value="ALL" />
11: </logger>
This way, the console output will display only the log statements from the Program class, the log file will contain the log statements from both Program class and MyClass class. Although MyClass doesn’t have an appender associated with it, the container namespace does and that appender who processes MyClass log statements. If you changed the level value to “OFF” for ConsoleApplication1.MyClass, the log file will not contain log statements from MyClass. When applying the previous technique keep into consideration the following:
Beside the expressions mentioned above, sometimes you need to log context information. Modify your console application to look so:
1: using System;
2: namespace ConsoleApplication1
3: {
4: class Program
5: {
6: private static log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
7: static void Main(string[] args)
8: {
9: log4net.Config.XmlConfigurator.Configure();
10: log4net.ThreadContext.Properties["myContext"] = "Logging from Main";
11: log.Info("Just info.");
12: Console.ReadLine();
13: }
14: }
15: }
Now update the app.config to look like:
1: <?xml version="1.0" enc
oding="utf-8" ?>
2: <configuration>
3: <configSections>
4:

6: </configSections>
7:
8: <log4net>
9:
10: <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
11: <layout type="log4net.Layout.PatternLayout">
12: <conversionPattern value="%logger (%property{myContext}) [%level]- %message%newline" />
13: </layout>
14: </appender>
15:
16: <root>
17: <level value="ALL" />
18: <appender-ref ref="ConsoleAppender" />
19: </root>
20: </log4net>
21: </configuration>
Compile and run, you will got a log statement similar to:
ConsoleApplication1.Program (Logging from Main) [INFO]- Just info.
What we did here is that we added a property “myContext” to the ThreadContext static class and assigned a simple string value. This prop erty processed by the appender through the %property{myContext} expression in the layout conversion pattern.
There are three hierarchy logging contexts available in log4net, where properties in the more granular contexts override property values in less granular contexts.
Context
Description
log4net.GlobalContext
A global context shared across all application threads and app domains. If two threads set the same property on the GlobalContext, one value will overwrite the other.
log4net.ThreadContext
Any properties set in this context are scoped to the calling thread. In other words, in this context two threads can set the same property to different values without stomping on each other.
log4net.ThreadLogicalContext
This context behaves similarly to the ThreadContext, except that the scope is defined by logical thread boundaries. I’ll be honest and say that I’ve never used the ThreadLogicalContext in my career, but if you’re working with a custom thread pool algorithm or hosting the CLR, you may find some use for this one.
Context property values don’t have to be strings. You can set the value of a context property to any object reference; then the object’s ToString can be used to obtain the needed context property when a logging event occurs. This technique could be used to log whatever state you want at the time of each logging event.
ThreadContext and ThreadLogicalContext can store property values in stacks available via the Stacks static property of each class. Pushing a property value onto a stack returns an IDisposable that, when disposed, pops the property value off of the stack. The logging output reflects the state of the context stack at each logging event; the stack is represented as a space-delimited list, with newer items appearing later in the list. Its like printing the current call stack in every log statement. check this example:
1: using System;
2: namespace ConsoleApplication1
3: {
4: class Program
5: {
6: private static log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
7: static void Main(string[] args)
8: {
9: log4net.Config.XmlConfigurator.Configure();
10: using (log4net.ThreadContext.Stacks["myContext"].Push("Main"))
11: {
12: FirstAction();
13: SecondAction();
14: }
15: Console.ReadLine();
16: }
17:
18: static void FirstAction()
19: {
20: using (log4net.ThreadContext.Stacks["myContext"].Push("FirstAction"))
21: {
22: UtilityRoutine();
23: }
24: }
25:
26: static void SecondAction()
27: {
28: using (log4net.ThreadContext.Stacks["myContext"].Push("SecondAction"))
29: {
30: UtilityRoutine();
31: FirstAction();
32: }
33: }
34:
35: static void UtilityRoutine()
36: {
37: using (log4net.ThreadContext.Stacks["myContext"].Push("UtilityRoutine"))
38: {
39: log.Info("this is an info message");
40: }
41: }
42: }
43: }
Compile and run, you will get these log messages:
ConsoleApplication1.Program (Main FirstAction UtilityRoutine) [INFO]- this is an info message
ConsoleApplication1.Program (Main SecondAction UtilityRoutine) [INFO]- this is an info message
ConsoleApplication1.Program (Main SecondAction FirstAction UtilityRoutine) [INFO]- this is an info message
Filters are applied to individual appenders via the log4net configuration, and they help the appender determine whether a log event should be processed by the appender. The following configuration defines two file appenders, each with a unique filter applied:
1: <?xml version="1.0" encoding="utf-8" ?>
2: <configuration>
3: <configSections>
4:

5: </configSections>
6: <log4net>
7: <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
8: <file value="log.txt" />
9: <filter type="log4net.Filter.LevelRangeFilter">
10: <levelMin value="DEBUG" />
11: <levelMax value="WARN" />
12: </filter>
13: <layout type="log4net.Layout.SimpleLayout" />
14: </appender>
15: <appender name="ErrorFileAppender" type="log4net.Appender.FileAppender">
16: <file value="errors.txt" />
17: <filter type="log4net.Filter.LevelRangeFilter">
18: <levelMin value="ERROR" />
19: <levelMax value="FATAL" />
20: </filter>
21: <layout type="log4net.Layout.SimpleLayout" />
22: </appender>
23: <root>
24: <level value="DEBUG" />
25: <appender-ref ref="LogFileAppender" />
26: <appender-ref ref="ErrorFileAppender" />
27: </root>
28: </log4net>
29: </configuration>
The filter on the first appender will log statements with levels DEBUG, INFO, and WARN; the filter on the second appender will log statements with levels ERROR and FATAL. There are many filters available in log4net, we will review them quickly.
log4net.Filter.LoggerMatchFilter Filters log events based on the name of the logger object from which they are emitted. This filter can be configured using the following properties:
log4net.Filter.LevelMatchFilter Filters log statements that match (or don’t match) a specific logging level. This filter can be configured using the following properties:
log4net.Filter.LevelRangeFilter Similar to the LevelMatchFilter, except that instead of filtering a single log level, this filters on an inclusive range of contiguous levels. This filter can be configured using the following properties:
log4net.Filter.StringMatchFilter Filters log events based on a string or regular expression match against the log message. This filter can be configured using the following properties:
log4net.Filter.PropertyFilter Filters log events based on a value or regular expression match against a specific context property.
log4net.Filter.DenyAllFilter This filter simply denies all filtering. When this is used, it’s always at the end of a filter chain to block unwanted log messages from the appender.
If you want comprehensive log to be there in case of errors but you worry about the resources consumed by logging, you might use lossy logging. Lossy logging gives the best of both worlds, under normal operation your application will not log any messages; however, if your application logs an error, a small batch of messages leading up to the error is placed into the log, giving you the error and a snapshot of system activity just before it happened.
Lets modify our code to be like:
1: using System;
2: namespace ConsoleApplication1
3: {
4: class Program
5: {
6: static log4net.ILog Log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
7: static void Main( string[] args )
8: {
9: log4net.Config.XmlConfigurator.Configure();
10: for( int i = 0; i < 100; ++i )
11: {
12: Log.DebugFormat( "this is debug msg #{0}", i );
13: }
14: Log.Error( "error: an error occurred!" );
15:
Log.Warn( "warning: you've been warned" );
16:
17: Console.ReadLine();
18: }
19: }
20: }
Let’s modify our app.config to look like:
1: <?xml version="1.0" encoding="utf-8" ?>
2: <configuration>
3: <configSections>
4:

5: </configSections>
6:
7: <log4net>
8: <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
9: <layout type="log4net.Layout.SimpleLayout" />
10: </appender>
11:
12: <appender name="LossyConsoleAppender" type="log4net.Appender.BufferingForwardingAppender">
13: <bufferSize value="20" />
14: <lossy value="true"/>
15: <evaluator type="log4net.Core.LevelEvaluator">
16: <threshold value="ERROR" />
17: </evaluator>
18: <appender-ref ref="ConsoleAppender" />
19: </appender>
20:
21: <root>
22: <level value="DEBUG" />
23: <appender-ref ref="LossyConsoleAppender" />
24: </root>
25: </log4net>
26: </configuration>
Compile and run, you will see output like:
The logging configuration defines two appenders, one very generic Console appender and a BufferingForwardingAppender. As the name implies, the latter appender buffers log messages and forwards them in batches to one or more other appenders. You can probably tell from the configuration XML that I’ve set this appender up with a 20-message buffer. The lossy and evaluator parameters work together to define when the log message buffer is forwarded to the “base” appender.
The program issues a total of 102 log messages (100 DEBUG, one ERROR, and one WARN), but the console only contains 20 messages (19 DEBUG and 1 ERROR). So what happened to the other 82 DEBUG and WARN messages?
When the BufferingForwardingAppender’s lossy property is enabled, the appender will buffer log messages without forwarding them. If the buffer fills up, the oldest messages are dropped from the buffer to make room for the new messages.
The evaluator property determines when the appender forwards the messages from the buffer to its base appenders. There is only one evaluator defined in log4net - the LevelEvaluator. The LevelEvaluator triggers the forward when a log message is received that meets or exceeds the configured threshold. The example above is configured so that an ERROR message triggers the appender to forward its buffer to the ConsoleAppender.
Lossy Appender Types log4net provides the following appenders that can operate “lossy” :
log4net.Appender.AdoNetAppender
log4net.Appender.RemotingAppender
log4net.Appender.SmtpAppender
log4net.Appender.SmtpPickupDirAppender
log4net.Appender.BufferingForwardingAppender
Sometimes we are in the mood to code as quickly as possible without getting into configuration files. Normally, that happens when we are trying to test something. In that case, you have another way to do the configuration. All of the long configuration files that we saw in the previous section can be defined programmatically using a few lines of code. See the following code:
1: // using a FileAppender with a PatternLayout
2: log4net.Config.BasicConfigurator.Configure( new log4net.Appender.FileAppender(new log4net.Layout.PatternLayout("%d [%t]%-5p %c [%x] <%X{auth}> - %m%n"),"testfile.log"));
3:
4: // using a FileAppender with an XMLLayout
5: log4net.Config.BasicConfigurator.Configure( new log4net.Appender.FileAppender(new log4net.Layout.XMLLayout(),"testfile.xml"));
6:
7: // using a ConsoleAppender with a PatternLayout
8: log4net.Config.BasicConfigurator.Configure( new log4net.Appender.ConsoleAppender(new log4net.Layout.PatternLayout("%d [%t] %-5p %c [%x] <%X{abc}> - %m%n")));
9:
10: // using a ConsoleAppender with a SimpleLayout
11: log4net.Config.BasicConfigurator.Configure( new log4net.Appender.ConsoleAppender(new log4net.Layout.SimpleLayout()));
You can see that while it is easy to code here, you can’t configure settings for individual loggers. All of the settings that are defined here are applied to the root logger.
1- Use a unique logger object for each type in your application and give it the class name. Like so:
static
log4net.ILog Log = log4net.LogManager.GetLogger(``System.Reflection.MethodBase.GetCurrentMethod().DeclaringType``);
2- Whenever you catch an exception, log it. Even if you just plan to throw it again, log it. In addition, log4net knows how to format Exception objects, so don’t try and build your own string from the exception data, just pass the exception to the logging statement. Like So:
Log.Error(``"An exception raised due to XYZ"``, ``e``);
3- Log to mark the activity and steps of your code.
4- Check for null references before logging any property. Logging code is code, and it should be treated the same way.
5- If an argument to the log method is expensive to obtain, be sure to guard your log statement with a check of the appropriate Is*Enabled property
if``( Log.IsDebugEnabled )``{ /* log statement */ }
6- Before an object calls on a shared dependency, consider pushing a tag onto the log context stack. This will allow you to determine the caller of the shared code that logged a particular message.
7- Whenever you use a formatted log statement, surround the format argument placeholders (the {}’s) with brackets or parentheses. This will mark the areas in each log message. This make the log scan a bit easier and makes empty or null formatting arguments more obvious.
INFO Level
DEBUG Level
ERROR Level
FATAL Level
In this post I tried to cover as much as possible about logging using log4net. Although logging is extremely useful, keep in mind that it is not free, it consumes resources and the more you log the less you can find. So be careful, and Good Luck.

John Holden announces new album
by https://www.facebook.com/progUK progger will release star-studded Rise And Fall in February...
UK multi-instrumentalist John Holden will release his new album, Rise And Fall, on February 29.
“I was delighted with the response to the first album and that gave me a lot of confidence," Holden tells Prog. "I believe these new compositions are even stronger and I am excited to see what reaction this album receives”
Rise And Fall features a host of guest performances including Oliver Wakeman, Nick D'Virgilio, former Renaissance bassist Jon Camp, Billy Sherwood, Mystery guitarist Michel St. Perre, Peter Jones, Joe Payne, Sally Minnear and more
“There are plenty of familiar faces making a return plus some amazing new talent. Everyone has added something unique and special," says Holden. “There are diverse topics ranging from cultural terrorism, enduring love, political commentary, addictions and even a flying monk! There are however recurring musical themes and lyrical ideas throughout and it feels very cohesive”, says Holden.
The full track listing is:
Leap of Faith
Rise and Fall
The Golden Thread
Dark Arts

Ancestors and Satellites


This section defines the virtual field and callback classes.
A virtual field is set of contiguous bits in one or more memory locations. The semantics and layout of virtual fields comes from an agreement between the software and the hardware, not any physical structures in the DUT.
| Virtual Register Field Classes | This section defines the virtual field and callback classes. |
| uvm_vreg_field | Virtual field abstraction class |
| uvm_vreg_field_cbs | Pre/post read/write callback facade class |
Virtual field abstraction class
A virtual field represents a set of adjacent bits that are logically implemented in consecutive memory locations.

function new( string name = "uvm_vreg_field" )
Create a new virtual field instance
This method should not be used directly. The uvm_vreg_field::type_id::create() method should be used instead.
function void configure( uvm_vreg parent, int unsigned size, int unsigned lsb_pos )
Instance-specific configuration
Specify the parent virtual register of this virtual field, its size in bits, and the position of its least-significant bit within the virtual register relative to the least-significant bit of the virtual register.
Get the simple name
Return the simple object name of this virtual field
virtual function string get_full_name()
Get the hierarchical name
Return the hierarchal name of this virtual field The base of the hierarchical name is the root block.
virtual function int unsigned get_lsb_pos_in_register()
Return the position of the virtual field / Returns the index of the least significant bit of the virtual field in the virtual register that instantiates it. An offset of 0 indicates a field that is aligned with the least-significant bit of the register.
virtual function int unsigned get_n_bits()
Returns the width, in bits, of the virtual field.
virtual function string get_access( uvm_reg_map map = null )
Returns the access policy of the virtual field register when written and read via an address map.
If the memory implementing the virtual field is mapped in more than one address map, an address map must be specified. If access restrictions are present when accessing a memory through the specified address map, the access mode returned takes the access restrictions into account. For example, a read-write memory accessed through an address map with read-only restrictions would return “RO”.
virtual task write( input longint unsigned idx, output uvm_status_e status, input uvm_reg_data_t value, input uvm_path_e path = UVM_DEFAULT_PATH, input uvm_reg_map map = null, input uvm_sequence_base parent = null, input uvm_object extension = null, input string fname = "", input int lineno = 0 )
Write the specified value in a virtual field
Write value in the DUT memory location(s) that implements the virtual field that corresponds to this abstraction class instance using the specified access path.
If the memory implementing the virtual register array containing this virtual field is mapped in more than one address map, an address map must be specified if a physical access is used (front-door access).
The operation is eventually mapped into memory read-modify-write operations at the location where the virtual register specified by idx in the virtual register array is implemented. If a backdoor is available for the memory implemeting the virtual field, it will be used for the memory-read operation.
virtual task read( input longint unsigned idx, output uvm_status_e status, output uvm_reg_data_t value, input uvm_path_e path = UVM_DEFAULT_PATH, input uvm_reg_map map = null, input uvm_sequence_base parent = null, input uvm_object extension = null, input string fname = "", input int lineno = 0 )
Read the current value from a virtual field
Read from the DUT memory location(s) that implements the virtual field that corresponds to this abstraction class instance using the specified access path, and return the readback value.
If the memory implementing the virtual register array containing this virtual field is mapped in more than one address map, an address map must be specified if a physical access is used (front-door access).
The operation is eventually mapped into memory read operations at the location(s) where the virtual register specified by idx in the virtual register array is implemented.
virtual task poke( input longint unsigned idx, output uvm_status_e status, input uvm_reg_data_t value, input uvm_sequence_base parent = null, input uvm_object extension = null, input string fname = "", input int lineno = 0 )
Deposit the specified value in a virtual field
Deposit value in the DUT memory location(s) that implements the virtual field that corresponds to this abstraction class instance using the specified access path.
The operation is eventually mapped into memory peek-modify-poke operations at the location where the virtual register specified by idx in the virtual register array is implemented.
virtual task peek( input longint unsigned idx, output uvm_status_e status, output uvm_reg_data_t value, input uvm_sequence_base parent = null, input uvm_object extension = null, input string fname = "", input int lineno = 0 )
Sample the current value from a virtual field
Sample from the DUT memory location(s) that implements the virtual field that corresponds to this abstraction class instance using the specified access path, and return the readback value.
If the memory implementing the virtual register array containing this virtual field is mapped in more than one address map, an address map must be specified if a physical access is used (front-door access).
The operation is eventually mapped into memory peek operations at the location(s) where the virtual register specified by idx in the virtual register array is implemented.
virtual task pre_write( longint unsigned idx, ref uvm_reg_data_t wdat, ref uvm_path_e path, ref uvm_reg_map map )
Called before virtual field write.
If the specified data value, access path or address map are modified, the updated data value, access path or address map will be used to perform the virtual register operation.
The virtual field callback methods are invoked before the callback methods on the containing virtual register. The registered callback methods are invoked after the invocation of this method. The pre-write virtual register and field callbacks are executed before the corresponding pre-write memory callbacks
virtual task post_write( longint unsigned idx, uvm_reg_data_t wdat, uvm_path_e path, uvm_reg_map map, ref uvm_status_e status )
Called after virtual field write
If the specified status is modified, the updated status will be returned by the virtual register operation.
The virtual field callback methods are invoked after the callback methods on the containing virtual register. The registered callback methods are invoked before the invocation of this method. The post-write virtual register and field callbacks are executed after the corresponding post-write memory callbacks
virtual task pre_read( longint unsigned idx, ref uvm_path_e path, ref uvm_reg_map map )
Called before virtual field read.
If the specified access path or address map are modified, the updated access path or address map will be used to perform the virtual register operation.
The virtual field callback methods are invoked after the callback methods on the containing virtual register. The registered callback methods are invoked after the invocation of this method. The pre-read virtual register and field callbacks are executed before the corresponding pre-read memory callbacks
virtual task post_read( longint unsigned idx, ref uvm_reg_data_t rdat, uvm_path_e path, uvm_reg_map map, ref uvm_status_e status )
Called after virtual field read.
If the specified readback data rdat or status is modified, the updated readback data or status will be returned by the virtual register operation.
The virtual field callback methods are invoked after the callback methods on the containing virtual register. The registered callback methods are invoked before the invocation of this method. The post-read virtual register and field callbacks are executed after the corresponding post-read memory callbacks

Sass layers are a way to group a set of related Sass variable definitions,
function/mixin declarations, and CSS rules into a single object. Use
sass_layer()
to create these objects, and sass_layer_merge()
to combine
two or more layer objects into a single layer; this ability to be merged is
the main benefit of using Sass layers versus lower-level forms of sass input.
sass_layer_merge(...) sass_layer( defaults = "", declarations = "", rules = "", html_deps = NULL, file_attachments = character(0), tags = character(0) )
| ... | A collection of |
|---|---|
| defaults | A suitable |
| declarations | A suitable |
| rules | A suitable |
| html_deps | An HTML dependency (or a list of them). |
| file_attachments | A named character vector, representing file assets that are referenced (using relative paths) from the sass in this layer. The vector names should be a relative path, and the corresponding vector values should be absolute paths to files or directories that exist; at render time, each value will be copied to the relative path indicated by its name. (For directories, the contents of the source directory will be copied into the destination directory; the directory itself will not be copied.) You can also omit the name, in which case that file or directory will be copied directly into the output directory. |
| tags | A character vector with zero or more elements. Can be used to preserve simple metadata as layers are merged. |

How To Use quick start guide
Quick Start Guide For Matching Lugs
Step 1: Clip the device to the drum hoop. Make sure the microphone end is over the drum head. Press power.
Step 2: Hit in the center of the drum head to measure the fundamental pitch. Your drum must be mounted or on a stand to resonate freely in order to measure the fundamental pitch (the fundamental pitch is the lowest and loudest pitch your drum produces).
Step 3: Hit one inch from any lug. You should get a reading that is 30-100% higher than the fundamental. If you don't get a reading that is 30-100% higher, just hit the same lug again or try hitting a different lug. Once you obtain the proper lug reading, press filter. After filter is set, you will see the reading displayed in the top left corner. Also, the asterisk symbol will light up. This will limit displayed readings to +/-18% of the filtered lug reading, thus filtering out higher and lower overtones.
Step 4: Go around to each lug, hitting one inch away from the lug. Adjust the lugs to an even pitch. If the lug pitch is lower, tighten the lug. If the lug pitch is too high, loosen the lug.
Note: When you tune the next drum or drum head make sure to turn the filter off and then repeat the process and reset the filter to the relevant lug pitch. Also, if you change the pitch of the drumhead substantially (more than 18%), you will also need to reset the filter to the current lug pitch.
Quick Start Guide For Measuring Fundamental Note
Step 1: Clip the device to the drum hoop. Make sure the microphone end is over the drum head. Press power, then press note.
Step 2: Hit in the center of the drum head to measure the fundamental pitch. Your drum must be mounted or on a stand to resonate freely in order to measure the fundamental pitch (the fundamental pitch is the lowest and loudest pitch your drum produces).
Step 3: After you hit the drum, the nearest note will be displayed on the LCD screen. Also, a needle will show you weather you are sharp or flat of the note. If the needle points to the left you are too low. If the needle points to the right you are too high. Adjust to the desired note by loosening or tightening the lugs. The needle should point straight when you are tuned to a note.

OECD: Global growth will be worst since financial crisis in 2019
by Harry RobertsonThe global economy is set to grow at its slowest pace since the financial crisis this year, the OECD has said, with governments failing to adequately tackle the problem.
In a gloomy update to its forecasts, the Paris-based organisation said countries were also failing on tackling climate change, the digitisation of economies and a breakdown of the rules-based global order.
The world economy is set to grow 2.9 per cent this year and in 2020, the OECD said, the weakest expansions for 10 years. In 2021, growth is predicted to rise to just three per cent.
OECD chief economist Laurence Boone said clear policies were needed to address the problem, otherwise “uncertainty will continue to loom high, damaging growth prospects”.
