The Events and Annotations
data structures¶
Events and annotations are quite similar. This tutorial highlights their differences and similarities, and tries to shed some light on which one is preferred to use in different situations when using MNE.
Both events and Annotations
can be seen as triplets
where the first element answers to when something happens and the last
element refers to what it is.
The main difference is that events represent the onset in samples taking into
account the first sample value
(raw.first_samp
), and the description is
an integer value.
In contrast, Annotations
represents the
onset
in seconds (relative to the reference orig_time
),
and the description
is an arbitrary string.
There is no correspondence between the second element of events and
Annotations
.
For events, the second element corresponds to the previous value on the
stimulus channel from which events are extracted. In practice, the second
element is therefore in most cases zero.
The second element of Annotations
is a float
indicating its duration in seconds.
See Reading an event file
for a complete example of how to read, select, and visualize events;
and Rejecting bad data (channels and segments) to
learn how Annotations
are used to mark bad segments
of data.
An example of events and annotations¶
The following example shows the recorded events in sample_audvis_raw.fif and marks bad segments due to eye blinks.
import os.path as op
import numpy as np
import mne
# Load the data
data_path = mne.datasets.sample.data_path()
fname = op.join(data_path, 'MEG', 'sample', 'sample_audvis_raw.fif')
raw = mne.io.read_raw_fif(fname)
Out:
Opening raw data file /home/circleci/mne_data/MNE-sample-data/MEG/sample/sample_audvis_raw.fif...
Read a total of 3 projection items:
PCA-v1 (1 x 102) idle
PCA-v2 (1 x 102) idle
PCA-v3 (1 x 102) idle
Range : 25800 ... 192599 = 42.956 ... 320.670 secs
Ready.
Current compensation grade : 0
First we’ll create and plot events associated with the experimental paradigm:
# extract the events array from the stim channel
events = mne.find_events(raw)
# Specify event_id dictionary based on the meaning of experimental triggers
event_id = {'Auditory/Left': 1, 'Auditory/Right': 2,
'Visual/Left': 3, 'Visual/Right': 4,
'smiley': 5, 'button': 32}
color = {1: 'green', 2: 'yellow', 3: 'red', 4: 'c', 5: 'black', 32: 'blue'}
mne.viz.plot_events(events, raw.info['sfreq'], raw.first_samp, color=color,
event_id=event_id)
Out:
320 events found
Event IDs: [ 1 2 3 4 5 32]
Next, we’re going to detect eye blinks and turn them into
Annotations
:
# find blinks
annotated_blink_raw = raw.copy()
eog_events = mne.preprocessing.find_eog_events(raw)
n_blinks = len(eog_events)
# Turn blink events into Annotations of 0.5 seconds duration,
# each centered on the blink event:
onset = eog_events[:, 0] / raw.info['sfreq'] - 0.25
duration = np.repeat(0.5, n_blinks)
description = ['bad blink'] * n_blinks
annot = mne.Annotations(onset, duration, description,
orig_time=raw.info['meas_date'])
annotated_blink_raw.set_annotations(annot)
# plot the annotated raw
annotated_blink_raw.plot()
Out:
EOG channel index for this subject is: [375]
Filtering the data to remove DC offset to help distinguish blinks from saccades

FIR filter parameters
---------------------
Designing a two-pass forward and reverse, zero-phase, non-causal bandpass filter:
- Windowed frequency-domain design (firwin2) method
- Hann window

- Lower transition bandwidth: 0.50 Hz (-12 dB cutoff frequency: 1.75 Hz)
- Upper passband edge: 45.00 Hz
- Upper transition bandwidth: 0.50 Hz (-12 dB cutoff frequency: 45.25 Hz)
- Filter length: 8192 samples (13.639 sec)
Setting up band-pass filter from 1 - 10 Hz
FIR filter parameters
---------------------
Designing a two-pass forward and reverse, zero-phase, non-causal bandpass filter:
- Windowed frequency-domain design (firwin2) method

- Lower passband edge: 1.00
- Lower transition bandwidth: 0.50 Hz (-12 dB cutoff frequency: 0.75 Hz)
- Upper passband edge: 10.00 Hz
- Upper transition bandwidth: 0.50 Hz (-12 dB cutoff frequency: 10.25 Hz)
- Filter length: 8192 samples (13.639 sec)
Now detecting blinks and generating corresponding events
Number of EOG events detected : 46
Add annotations to raw objects¶
An important element of Annotations
is
orig_time
which is the time reference for the onset
.
It is key to understand that when calling
raw.set_annotations
, given
annotations are copied and transformed so that
raw.annotations.orig_time
matches the recording time of the raw object.
Refer to the documentation of Annotations
to see
the expected behavior depending on meas_date
and orig_time
.
Where meas_date
is the recording time stored in
Info
.
You can find more information about Info
in
The Info data structure.
We’ll now manipulate some simulated annotations.
The first annotations has orig_time
set to None
while the
second is set to a chosen POSIX timestamp for illustration purposes.
Note that both annotations have different onset
values.
# Create an annotation object with orig_time undefined (default)
annot_none = mne.Annotations(onset=[0, 2, 9], duration=[0.5, 4, 0],
description=['foo', 'bar', 'foo'],
orig_time=None)
print(annot_none)
# Create an annotation object with orig_time
orig_time = '2002-12-03 19:01:31.676071'
annot_orig = mne.Annotations(onset=[22, 24, 31], duration=[0.5, 4, 0],
description=['foo', 'bar', 'foo'],
orig_time=orig_time)
print(annot_orig)
Out:
<Annotations | 3 segments : foo (2), bar (1), orig_time : None>
<Annotations | 3 segments : foo (2), bar (1), orig_time : 2002-12-03 19:01:31.676071>
Now we create two raw objects and set each with different annotations. Then we plot both raw objects to compare the annotations.
# Create two cropped copies of raw with the two previous annotations
raw_a = raw.copy().crop(tmax=12).set_annotations(annot_none)
raw_b = raw.copy().crop(tmax=12).set_annotations(annot_orig)
# Plot the raw objects
raw_a.plot()
raw_b.plot()
Note that although the onset
values of both annotations were different,
due to complementary orig_time
they are now identical. This is because
the first one (annot_none
), once set in raw, adopted its orig_time
.
The second one (annot_orig
) already had an orig_time
, so its
orig_time
was changed to match the onset time of the raw. Changing an
already defined orig_time
of annotations caused its onset
to be
recalibrated with respect to the new orig_time
. As a result both
annotations have now identical onset
and identical orig_time
:
# Show the annotations in the raw objects
print(raw_a.annotations)
print(raw_b.annotations)
# Show that the onsets are the same
np.set_printoptions(precision=6)
print(raw_a.annotations.onset)
print(raw_b.annotations.onset)
Out:
<Annotations | 3 segments : foo (2), bar (1), orig_time : 2002-12-03 19:01:10.720100>
<Annotations | 3 segments : foo (2), bar (1), orig_time : 2002-12-03 19:01:10.720100>
[42.955971 44.955971 51.955971]
[42.955971 44.955971 51.955971]
Notice again that for the case where orig_time
is None
,
it is assumed that the orig_time
is the time of the first sample of data.
raw_delta = (1 / raw.info['sfreq'])
print('raw.first_sample is {}'.format(raw.first_samp * raw_delta))
print('annot_none.onset[0] is {}'.format(annot_none.onset[0]))
print('raw_a.annotations.onset[0] is {}'.format(raw_a.annotations.onset[0]))
Out:
raw.first_sample is 42.95597082905339
annot_none.onset[0] is 0.0
raw_a.annotations.onset[0] is 42.955970883369446
Valid operations in mne.Annotations
¶
Concatenate¶
It is possible to concatenate two annotations with the + operator (just like
lists) if both share the same orig_time
annot = mne.Annotations(onset=[10], duration=[0.5],
description=['foobar'],
orig_time=orig_time)
annot = annot_orig + annot # concatenation
print(annot)
Out:
<Annotations | 4 segments : foobar (1), foo (2), bar (1), orig_time : 2002-12-03 19:01:31.676071>
Iterating, Indexing and Slicing mne.Annotations
¶
Annotations
supports iterating, indexing and slicing.
Iterating over Annotations
and indexing with an integer returns
a dictionary. While slicing returns a new Annotations
instance.
See the following examples and usages:
# difference between indexing and slicing a single element
print(annot[0]) # indexing
print(annot[:1]) # slicing
Out:
OrderedDict([('onset', 10.0), ('duration', 0.5), ('description', 'foobar'), ('orig_time',<PHONE_NUMBER>.676071)])
<Annotations | 1 segment : foobar (1), orig_time : 2002-12-03 19:01:31.676071>
How about iterations?
for key, val in annot[0].items(): # iterate on one element which is dictionary
print(key, val)
Out:
onset 10.0
duration 0.5
description foobar
orig_time<PHONE_NUMBER>.676071
for idx, my_annot in enumerate(annot): # iterate on the Annotations object
print('annot #{0}: onset={1}'.format(idx, my_annot['onset']))
print('annot #{0}: duration={1}'.format(idx, my_annot['duration']))
print('annot #{0}: description={1}'.format(idx, my_annot['description']))
Out:
annot #0: onset=10.0
annot #0: duration=0.5
annot #0: description=foobar
annot #1: onset=22.0
annot #1: duration=0.5
annot #1: description=foo
annot #2: onset=24.0
annot #2: duration=4.0
annot #2: description=bar
annot #3: onset=31.0
annot #3: duration=0.0
annot #3: description=foo
for idx, my_annot in enumerate(annot[:1]):
for key, val in my_annot.items():
print('annot #{0}: {1} = {2}'.format(idx, key, val))
Out:
annot #0: onset = 10.0
annot #0: duration = 0.5
annot #0: description = foobar
annot #0: orig_time =<PHONE_NUMBER>.676071
Iterating, indexing and slicing return a copy. This has implications like the fact that changes are not kept.
# this change is not kept
annot[0]['onset'] = 42
print(annot[0])
# this change is kept
annot.onset[0] = 42
print(annot[0])
Out:
OrderedDict([('onset', 10.0), ('duration', 0.5), ('description', 'foobar'), ('orig_time',<PHONE_NUMBER>.676071)])
OrderedDict([('onset', 42.0), ('duration', 0.5), ('description', 'foobar'), ('orig_time',<PHONE_NUMBER>.676071)])
Save¶
Note that you can also save annotations to disk in FIF format:
>>> annot.save('my-annot.fif')
Or as CSV with onsets in (absolute) ISO timestamps:
>>> annot.save('my-annot.csv')
Or in plain text with onsets relative to orig_time
:
>>> annot.save('my-annot.txt')
Total running time of the script: ( 0 minutes 8.688 seconds)
Estimated memory usage: 8 MB

java.lang.Object cetus.analysis.AnalysisPass cetus.analysis.PointsToAnalysis
public class PointsToAnalysis
The Points-To Analyzer creates intraprocedural pointer
relationships for C programs. Pointer variables are
variables that store the address-value of a memory
location and are said to point-to or reference that
memory location. The points-to analyzer implemented
here is flow sensitive and hence, provides pointer
relationships at every program point i.e. every
relevant Statement in the program. Pointer relationships
are represented using PointsToDomain
and
PointsToRel
, which make use of different
Symbol
information to a large extent. Aggregate
structures such as arrays are handled conservatively,
while struct types are handled more precisely. The
analyzer also supports useful, but conservative,
information handling for heap-allocated variables.
The analyzer is directly used by the Interprocedural Points-to Analyzer, to provide advanced static-time pointer information. Thus, function calls inside of procedures can be supported during intraprocedural analysis.
The analysis is implemented based on the design described in the following M.S. Thesis:
"A Practical Interprocedural Alias Analysis for an Optimizing/Parallelizing C Compiler", Maryam Emami, 1993.

This page discusses the mechanism behind building and installing Tcl
extensions.
To build and install all the Tcl extensions, set the PTARCH
environment
variable. This variable is used to differentiate between different
architectures. To set the PTARCH
variable,
under /bin/csh
, do:
setenv PTARCH `$TYCHO/bin/ptarch`To do the build:
cd $TYCHO make tclexts
Tycho uses GNU autoconf to configure the Tcl extensions.
$TYCHO/makefile
has a rule that calls configure
and builds the proper directories.
configure
has a number of options, type
$TYCHO/src/configure -help
to see them. To pass options to
configure
, set the CONFIGURE_ARGS
option.
The tclexts
makefile rule configures, builds and installs
all the tcl extensions. Below we discuss each step in turn:
config_tclexts
$TYCHO/obj.$PTARCH
and then runs
configure
, which creates the makefiles
below
$TYCHO/obj.$PTARCH
.
all_tclexts
$TYCHO/obj.$PTARCH
and builds
all the binaries.
install_tclexts
$TYCHO/obj.$PTARCH
and installs
the shared libraries into $TYCHO/lib.$PTARCH
$TYCHO/makefile
is setup to support multiple architectures
by creating separate lib.$PTARCH
and obj.$PTARCH
directories. It is possible to
call configure
directly and create binaries in
$TYCHO/src
, but there are the following problems:
$TYCHO/lib.$PTARCH
directory is not
built automatically, you would need to do something like:
cd $TYCHO/src configure mkdir ../lib.$PTARCH make install
$TYCHO/src/tcl.mk
was configured for our local installation and are unlikely to work
for you. To rebuild these files, run configure
.
$TYCHO/obj.$PTARCH/tcl.mk
to be present.
configure.in
which autoconf
converts to a configure
script.
The user runs configure
which examines the operating
systems for idiosyncrasies and then reads in the makefile.in
template file and produces
a makefile
. The user can then run make
and
compile and install the package.
The user need not have autoconf
installed to run
configure
. The autoconf
package need only
be present if the user wishes to modify configure.in
and
produce a new configure
file. If autoconf
is not available, then it is possible to edit the configure
file directly; it is merely a /bin/sh
script.
In Tcl7.5 and later it is fairly easy to load shared objects that
add new Tcl commands. The Tcl load
and
package
command man pages cover the details.
The general overview is that C code is compiled with special flags
to build a shared object. The special flags are compiler and
architecture dependent, configure
determines these flags
by reading the tclConfig.sh
file located in the
architecture dependent Tcl library directory.
The shared object has an architecture-dependent file extension,
such as .so
under Solaris 2, and .sl
under
HPUX. To see what the extension is on your system, start up
tclsh
or itkwish
and run info sharedlibextension
.
When the file is loaded by Tcl, a C initialization procedure is
called by Tcl. The name of the procedure depends on the name of the
package or file that is being loaded, see the Tcl load
command documentation. Usually, this procedure is used to create new
Tcl commands that call user-supplied C procedures.
If you use Tycho to open a file with the sharedlibextension
then Tycho passes that file to the Tcl load
command.
$TYCHO/makefile
tclexts
rule which
configures, builds and installs the extensions. This file is
described above in more detail.
$TYCHO/src
$TYCHO/obj.$PTARCH
$TYCHO/lib.$PTARCH
src/configure.in
autoconf
uses to
create src/configure
.
src/configure
src/makefile.in
makefile
is generated.
mk/tcl.mk.in
obj.$PTARCH/tcl.mk
.
$TYCHO/src
for your extension.
$TYCHO/src/configure.in
and add the makefile to the AC_OUTPUT()
macro.
$TYCHO/makefile
rules should automatically run
autoconf
and update src/configure
.
$TYCHO/src/makefile.in
and add your extension directory to the DIRS
macro.
makefile.in
from another directory, such as
src/tytimer/makefile.in
to the directory for your extension.
makefile.in
appropriately.
makefile.in
of your extension to $TYCHO/makefile
so that when
others run make sources
, your makefile will be retrieved
from version control.
cd $TYCHO make tclexts


Constant Index
+P-OBJECT+
The serialization marker for cached objects.
+POINTER-SIZE+
The number of octets for a heap pointer.


Background
Clustering is an unsupervised machine learning approach where the aim i to determine “natural” or “data-driven” groups in the data without using apriori knowledge about labels or categories. The challenges in unsupervised clustering is that it always produces a partitioning of the samples since each clustering method implicitly impose a structure on the data. The question is: What is a “good” clustering? We need to evaluate the results based on the clustering tendency, number of clusters and the clustering quality.
Aim
clusteval
is a Python package that is developed to evaluate the clustering tendency, number of clusters and clustering quality. clusteval
returns the cluster labels for the optimal number of cluster that produces the best partitioning of the samples. The following evaluation strategies are implemented: silhouette, dbindex, and derivative which can be used in combination with agglomerative and kmeans clustering. In addition dbscan and hdbscan is implemented for which an internal gridsearch scheme will determine the best partitioning.
Note
The clusteval
library gridsearches across the number of clusters, and method-parameters to determine the optimal number of clusters given the input dataset.
Quickstart
A quick example how to learn a model on a given dataset.
# Import library
from clusteval import clusteval
# Initialize
cl = clusteval()
# Generate random data
X, y = cl.import_example(data='blobs')
# Fit data X
results = ce.fit(X)
# Plot
ce.plot()
ce.plot_silhouette()
ce.scatter()
ce.dendrogram()

See the
release notes for descriptions
of new functionality and more.
The Zoltan Library provides critical data-management services
to a wide range of parallel applications. Zoltan includes many utilities
needed by unstructured and/or adaptive parallel applications. These utilities
include
Zoltan's object-oriented interface is easy-to-use and enables
Zoltan to be used by a number of different applications. Zoltan is
designed to be flexible and extensible, so different algorithms can be
used, compared and added easily.
Why Zoltan is needed:
-
In some applications, work loads and/or geometric locality change as computations
proceed;
Zoltan provides dynamic redistribution of data to maintain high
performance.
-
Adaptive finite element methods
-
Particle methods
-
Contact detection algorithms
-
Multiphysics simulations
-
Adaptive physics models
-
Processors need to track off-processor data's locations in dynamic
environments; Zoltan's distributed data directories allow applications to
efficiently query and update off-processor data locations.
-
Unstructured and adaptive applications require complicated interprocessor
communication; Zoltan's unstructured communication package
manages sends and receives for application developers.
-
State-of-the-art parallel computers often do not have sophisticated
debugging
tools available; Zoltan's dynamic memory management package simplifies
location of memory leaks and other memory errors.
Advantages of using Zoltan in applications:
Advantages of using Zoltan for developing new algorithms:

Turn off event triggering
noEvent(expr)
Real elementary relations within expr are taken literally, i.e., no state or time event is triggered.
The noEvent operator implies that real elementary expressions are taken literally instead of generating crossing functions. The smooth operator should be used instead of noEvent, in order to avoid events for efficiency reasons. A tool is free to not generate events for expressions inside smooth. However, smooth does not guarantee that no events will be generated, and thus it can be necessary to use noEvent inside smooth. [Note that smooth does not guarantee a smooth output if any of the occurring variables change discontinuously.]
[Example:
Real x, y, z; equation x = if time<1 then 2 else time-2; z = smooth(0, if time<0 then 0 else time); y = smooth(1, noEvent(if x<0 then 0 else sqrt(x)*x)); // noEvent is necessary.
]
der(h)=if noEvent(h>0) then -c*sqrt(h) else 0;


Main Concepts
About Modules - Modules dependencies
-
When you will work on big applications, you will want to split your code
-
Split your code is already done by using single files for Component, Services,
Pipes and so on
-
But what if you want to create such kind of reusable libraries?
For that, you will need to create custom modules that can be imported in other modules
-
By default, the Component/Directives/Pipes that you will create
in your module are not available for other ones (if module A imports module B, by default, A can't access to custom B's components)
-
To make a Component/Directives/Pipes available, you have to use the
exports field
@Component({
selector:'cmp2',
template:`{{'Sub component' | customPipe}}`
})
class Cmp2{}
@Component({
selector:'usefull-cmp',
template:`...`
})
class UsefullComponent{}
@NgModule({
imports: [BrowserModule],
declarations: [UsefullComponent], //usable in the module itsel
exports:[UsefullComponent, BrowserModule] // usable in module which import BrowserModule
})
export class LibModule { }
-
In the example below, an other module is exported from LibModule, it
means that a module which imports LibModule won't needd to import BrowserModule
manually


EXCLUSIVE: Marcellus Wiley on Kaepernick Messing Up 4 Potential NFL Offers (Flashback)
by Jessica ToddIn this flashback, Marcellus Wiley opened up to VladTV about believing Kaepernick still has the athletic ability to play for an NFL team, but he explained why talent isn't the only thing that gets you the job. He went on to speak about Kaepernick's settlement with the NFL and not believing that it implies the NFL was guilty, as Marcellus explained that it's normally cheaper to settle lawsuits than fight them. To hear more, including Marcellus breaking down how he thinks Kaepernick messed up 4 potential NFL deals, hit the above clip.

Our program is a unique blend of the Montessori way of learning and an academic based environment. In order to foster all aspects of age-appropriate development, each day at Little Scholars Nest Preschool is planned to reflect a balance of both individual confidence and group exposure, outdoor/indoor activities, active/quiet activities, free play, and structured/guided exercises. Our aim is to blossom a child’s personality in every aspect. We are dedicated to providing each child with fun, challenging activities that engage the imagination and enhance cognitive skills through play and hands-on activities.
Program Highlights
The following descriptions provide a brief overview of each individual program we offer. To take a look at our curriculum for the school year and more specifics regarding the daily schedule, please contact us to schedule a preschool visit.
The preschool group is for children of ages three to four.
We are dedicated to providing each child with fun, challenging activities that engage the imagination and enhance cognitive skills through play and hands-on activities. Our preschool group develops the skills needed to understand and appreciate the world around them. They are introduced to early Language Arts and Math concepts of letters, letter sounds, uppercase/lowercase letters, as well as numbers, colors, shapes, and phonics.
We focus on developing the following skills:
The pre-kindergarten group is for children of ages four to five.
This program focuses on school readiness by introducing children to specific academic subjects through hands-on activities, teacher instruction, and class discussions. Our way of teaching incorporates child-directed activities which instills the love of learning in our Little Scholars.
Phonics, decoding, sight words, blending, story comprehension, and journal writing are all part of our language arts program. We also have a very successful Reading Program, which incorporates “Story Time” and puppet plays to soar your child’s imagination.
Additionally, we introduce math concepts of counting, sorting, number words, addition, subtraction, time, money, shapes, estimation, counting by twos and fives, and much more are taught using fun activities as well as part of our written work packets. Science is part of our monthly curriculum and most of our Show and Tell topics are based on the science theme of the week. Concepts of: touch & senses, plants & animals, the human body, daily calendar (weather, date, and time), the solar system, and the study of our planet Earth, etc. are introduced. We incorporate nature walks and park visits as a part of learning scientific facts.
The after-school program is for kindergarteners and transitional kindergarten. This includes children of ages four to five.
Students are picked up from their respective elementary schools and participate in lunchtime upon arrival, which is followed by outdoor playtime. In the daily schedule, students will have to work with teachers on their homework and existential academic learning. Students in this program also participate in the daily naptime and evening creative activities.
The preschool part-time program runs Monday to Friday from 9:00 am to 1:00 pm at $950.00 per month.

Any document starts with a heading. You can use different sizes for your headings. HTML also has six levels of headings, which use the elements
,
,
,
,
, and
. While displaying any heading, browser adds one line before and one line after that heading.
<!DOCTYPE html>   <title>Heading Example</title>
This is heading 1

This is heading 2

This is heading 3

This is heading 4

This is heading 5

This is heading 6

The
 tag offers a way to structure your text into different paragraphs. Each paragraph of text should go in between an opening
 and a closing
 tag as shown below in the example −
<!DOCTYPE html>   <title>Paragraph Example</title>
Here is a first paragraph of text.

Here is a second paragraph of text.

Here is a third paragraph of text.
  »
Whenever you use the
 element, anything following it starts from the next line. This tag is an example of an empty element, where you do not need opening and closing tags, as there is nothing to go in between them.
The
 tag has a space between the characters br and the forward slash. If you omit this space, older browsers will have trouble rendering the line break, while if you miss the forward slash character and just use
 it is not valid in XHTML.
<!DOCTYPE html>   <title>Line Break Example</title>
Hello
 You delivered your assignment ontime.
 Thanks
 Mahnaz
  »
You can use  tag to put any content in the center of the page or any table cell.
<!DOCTYPE html>   <title>Centring Content Example</title>
This text is not in the center.

This text is in the center.
   »
Horizontal lines are used to visually break-up sections of a document. The
 tag creates a line from the current position in the document to the right margin and breaks the line accordingly.
For example, you may want to give a line between two paragraphs as in the given example below −
<!DOCTYPE html>   <title>Horizontal Line Example</title>
This is paragraph one and should be on top

This is paragraph two and should be at bottom
  »
Again
 tag is an example of the empty element, where you do not need opening and closing tags, as there is nothing to go in between them.
The
 element has a space between the characters hr and the forward slash. If you omit this space, older browsers will have trouble rendering the horizontal line, while if you miss the forward slash character and just use
 it is not valid in XHTML
Sometimes, you want your text to follow the exact format of how it is written in the HTML document. In these cases, you can use the preformatted tag
.
Any text between the opening
 tag and the closing
 tag will preserve the formatting of the source document.
<!DOCTYPE html>   <title>Preserve Formatting Example</title>
 function testFunction( strText ){ alert (strText) }

Suppose you want to use the phrase "12 Angry Men." Here, you would not want a browser to split the "12, Angry" and "Men" across two lines −
An example of this technique appears in the movie "12 Angry Men."
In cases, where you do not want the client browser to break text, you should use a nonbreaking space entity instead of a normal space. For example, when coding the "12 Angry Men" in a paragraph, you should use something similar to the following code −
<!DOCTYPE html>   <title>Nonbreaking Spaces Example</title>
An example of this technique appears in the movie "12 Angry Men."

The Cairo library is a vector graphics library with a powerful rendering model. It has such features as anti-aliased primitives, alpha-compositing, and gradients. Multiple backends for Cairo are available, to allow rendering to images, to PDF files, and to the screen on X and on other windowing systems. The functions in this section allow using Pango to render to Cairo surfaces.
Using Pango with Cairo is straightforward. A PangoContext created
with pango_cairo_font_map_create_context()
can be used on any
Cairo context (cairo_t), but needs to be updated to match the
current transformation matrix and target surface of the Cairo context
using pango_cairo_update_context()
. The convenience functions
pango_cairo_create_layout()
and pango_cairo_update_layout()
handle
the common case where the program doesn't need to manipulate the
properties of the PangoContext.
When you get the metrics of a layout or of a piece of a layout using
functions such as pango_layout_get_extents()
, the reported metrics
are in user-space coordinates. If a piece of text is 10 units long,
and you call cairo_scale (cr, 2.0), it still is more-or-less 10
units long. However, the results will be affected by hinting
(that is, the process of adjusting the text to look good on the
pixel grid), so you shouldn't assume they are completely independent
of the current transformation matrix. Note that the basic metrics
functions in Pango report results in integer Pango units. To get
to the floating point units used in Cairo divide by PANGO_SCALE
.

Once you build and run the example code above, you should see the following result:
PangoFontMap *
pango_cairo_font_map_get_default (void
);
Gets a default PangoCairoFontMap to use with Cairo.
Note that the type of the returned object will depend on the particular font backend Cairo was compiled to use; You generally should only use the PangoFontMap and PangoCairoFontMap interfaces on the returned object.
The default Cairo fontmap can be changed by using
pango_cairo_font_map_set_default()
. This can be used to
change the Cairo font backend that the default fontmap
uses for example.
Note that since Pango 1.32.6, the default fontmap is per-thread. Each thread gets its own default fontmap. In this way, PangoCairo can be used safely from multiple threads.

Sets a default PangoCairoFontMap to use with Cairo.
This can be used to change the Cairo font backend that the default fontmap uses for example. The old default font map is unreffed and the new font map referenced.
Note that since Pango 1.32.6, the default fontmap is per-thread.
This function only changes the default fontmap for
the current thread. Default fontmaps of exisiting threads
are not changed. Default fontmaps of any new threads will
still be created using pango_cairo_font_map_new()
.
A value of NULL
for fontmap
will cause the current default
font map to be released and a new default font
map to be created on demand, using pango_cairo_font_map_new()
.
Since: 1.22
PangoFontMap *
pango_cairo_font_map_new (void

Creates a new PangoCairoFontMap object; a fontmap is used
to cache information about available fonts, and holds
certain global parameters such as the resolution.
In most cases, you can use pango_cairo_font_map_get_default()
instead.
Note that the type of the returned object will depend on the particular font backend Cairo was compiled to use; You generally should only use the PangoFontMap and PangoCairoFontMap interfaces on the returned object.
You can override the type of backend returned by using an
environment variable PANGOCAIRO_BACKEND
. Supported types,
based on your build, are fc (fontconfig), win32, and coretext.

PangoContext *
pango_cairo_create_context (cairo_t *cr
);
Creates a context object set up to match the current transformation
and target surface of the Cairo context. This context can then be
used to create a layout using pango_layout_new()
.
This function is a convenience function that creates a context using
the default font map, then updates it to cr
. If you just need to
create a layout for use with cr
and do not need to access PangoContext
directly, you can use pango_cairo_create_layout()
instead.
Since: 1.22
void pango_cairo_update_context (cairo_t *cr
,PangoContext *context
);
Updates a PangoContext previously created for use with Cairo to
match the current transformation and target surface of a Cairo
context. If any layouts have been created for the context,
it's necessary to call pango_layout_context_changed()
on those
layouts.
Since: 1.10
PangoLayout *
pango_cairo_create_layout (cairo_t *cr
);
Creates a layout object set up to match the current transformation
and target surface of the Cairo context. This layout can then be
used for text measurement with functions like
pango_layout_get_size()
or drawing with functions like
pango_cairo_show_layout()
. If you change the transformation
or target surface for cr
, you need to call pango_cairo_update_layout()
This function is the most convenient way to use Cairo with Pango, however it is slightly inefficient since it creates a separate PangoContext object for each layout. This might matter in an application that was laying out large amounts of text.
Since: 1.10
void pango_cairo_update_layout (cairo_t *cr

Updates the private PangoContext of a PangoLayout created with
pango_cairo_create_layout()
to match the current transformation
and target surface of a Cairo context.

Draws the glyphs in glyphs
in the specified cairo context.
The origin of the glyphs (the left edge of the baseline) will
be drawn at the current point of the cairo context.
Since: 1.10
void pango_cairo_show_glyph_item (cairo_t *cr
,const char *text
,PangoGlyphItem *glyph_item
);
Draws the glyphs in glyph_item
in the specified cairo context,
embedding the text associated with the glyphs in the output if the
output format supports it (PDF for example), otherwise it acts
similar to pango_cairo_show_glyph_string()
.
The origin of the glyphs (the left edge of the baseline) will be drawn at the current point of the cairo context.
Note that text
is the start of the text for layout, which is then
indexed by

Zimbabwean CLOCKS 350km/hr with Audi RS.Watch the Daredevil’s Video
by Masikati NyashaZimbabwean CLOCKS 350km/hr with Audi RS
This unidentified Zimbabwean ‘speed demon’ recorded himself clocking 350km/hr with an Audi RS, while blasting Reverend T Chivaviro’s Tariro Yangu.
One word, exhilarating!
The driver seems to have performed the daring stunt on the popular German autobahn which generally doesn’t have speed limits, somewhere near the city of Stuttgart.
We are just not sure which ‘home’ he was missing at that particular moment, Zimbabwe or the heavens by driving at such adrenaline-pumping speeds.
The Audi RS which suffered his merciless accelerations is from the family of high-performance range versions manufactured by the German automotive company AUDI AG, a member of the Volkswagen Group.
Watch the Video Below
Any speed demons amongst you readers?
UPDATE: After further verifications the title of this article is inaccurate, the man behind the wheel is a professional and not a Zimbabwean as written earlier. Please don’t try this at home.

Page Objects
What are Page Objects?
Page Object Blog Post by Martin Fowler
A page object wraps an HTML page, or fragment, with an application-specific API, allowing you to manipulate page elements without digging around in the HTML.
Page objects are a way to describe UI interactions in your page with application specific terminology instead of HTML specific language.
This in turn helps you write tests that are more clear and also helps you be more dry (Don’t Repeat yourself) because you can reuse your page objects in other acceptance/end-to-end tests
Normal HTML Page Structure

Here using ember acceptance testing syntax we can grab the list of names: find('.page_container-list')
The problem with this is that it is not as descriptive as it could be
Page Object Pattern
Here is a sample Page Object:
const usersList = {
actionHeroes() {
return find('.page_container-list');
}
};
Now we can grab the list of action heroes like this: usersList.actionHeroes()
Suppose we wanted to get the total count of action heroes, we could use the ember acceptance testing syntax as follows:
find('.page_container-list').length
but instead we can create a function that returns the total count of superheroes using Page Object Design Pattern like this:
const usersList = {
actionHeroes() {
return find('.page_container-list');
},
totalNumberOfActionHeroes() {
return find('.page_container-list').length;
}
};
so now using our Page Object pattern we can grab the list of superheroes as follows: usersList.totalNumberOfActionHeroes();
which is more descriptive.
Additionally this helps make our acceptance tests more reusable
Page Object Methods
Page Objects can also contain UI interaction flows.
For example:
Say User A logs into your app and then wants to go to his settings page to update his login information.
Using the Page Object Pattern we can construct the following Page Object:
const UserLogin = {
login({
username,
password
}) {
return authenticateToSystem(username, password);
},
visitSettings() {
return visit('/settings');
}
}
Now we can just do UserLogin.login('jbelmont', 'somepassword').visitSettings();
and both login and go to the User Settings Page.
Page Object Method Scenario
Say that we want to update the username of a specific user in a possible admin list
Using Page Object pattern we could do the following:
const AdminPage = {
login({
username,
password
}) {
return authenticateToSystem(username, password);
},
visitAdmin(adminToken) {
return visit(adminToken, '/admin');
},
updateAdminUsername(username) {
this._setInput(username);
this._saveUsername(adminToken, username);
},
_setInput(newUserName) {
document.querySelector('.admin__input').value = newUserName;
},
_saveUsername(adminToken, username) {
db.saveNewUsername(adminToken, username);
}
}
Now with this possible Page Object we could do the following:
AdminPage
.login({
username: 'cnorris',
password: 'highkicker'
})
visitAdmin('someAdminToken1234')
.updateAdminUsername('jrambo', 'someAdminToken1234');
Although this a contrived example and not necessarily a secure way to update a username, it does illustrate the power of Page Objects!
Page Object Libraries
End to end testing libraries tend to have a page object pattern that is baked into them.
Here is a list of End to End Testing libraries that have them:

It all started on a school night, ya a school night. i was in grade 10 at the time and was in a big drug experiment phase. i had done shrooms a few days before and was doing them like every week so i thought i would be fine...i was wrong.
I had only got drunk on a school night, never shroomed so i decided to. hey...i had the resources. at around 10 my brother and I prepared the room for maximum trippage, always get a full outcome from what you buy. we set up his tv with a PS1, then grabbed my strobe light and my black light.
At around 10:15 we ate them.
I started to feel if at like 11:30 while playing some Sega Tennis cause the ball started to streak and i couldnt focus. about 10 mins after that my brother turned it off and we put in our trip CD with some Bone Thugs N Harmony and techo and trip songs into the PS1 and sat back and enjoyed the show for a bit.
after a bit of staring mindlessly at the screen we turned the strobe light on and that somehow brought all of what was on the screen onto the walls, i danced around in colours that i cant explain. during this we had a very deep conversaion about life n stuff like that, senses, gravity everything that is wierd. i turned on the black light (about 2 hours 15 mins after eating) and this made the conversation deeper n deeper, i remeber only seeing my brothers white shirt n white socks and nothin in the middle...it was wierd.
about 2:30 into the experience we were having fun so my brother cranked out a half gram of coke that we split...IT WAS ALL DOWNHILL FROM HERE. and when i say downhill...i mean i was on a hill that peaked in heaven (where i was at the time) and bottomed in hell (where i was after the yayo). i bucked my 1/4 gram rail and so did my brother and we went and sat down on the bed and strobed it up with the light.
After about 30 mins after the coke i started to feel sick. i remember turning around and staring out a huge window onto the ocean and then breathing fresh air and i felt the coldness from outside tho no window was open. I kept saying i fell sick...i feel sick...but my brother was fine. The coke made the shrooms like taking 2x as much in dosage..it was like i did 10 grams of shrooms to me...i could not focus on anything and everything echoed and had a stream behind it...i remember the song at the time..it was Devon the Dude : Doobie Ashtray...to this day i can't listen to it.
i left to go to my room and then was suddenly lying in my bed. this is where it gets foggy and hard to remember but ill try. My brother was calling 'are you ok' through the wall and i kept yelling ya ya..but i dont think he could here me..i dont think i said anything...my heart was beating a million times a minute and i thought i was going to die cause i had no clue what shroom and coke where like while mixed.
the walls where bending inward to me. i got up to go pee ( i had to pee a lot that night ) and fell on the floor. when i looked up people were pointing and laughing at me...tall people in retro colors. then i closed my eyes but when i did this it only opened them to a new room full of pools and waterfalls...i opened them and the people where gone.
I heard a scratchin at the door so i crawled over to it and opened it and my cat ran in. this scared me and i fell back to a sitting position against the wall and look at the cat. then the cat said something to me ill never forget 'YOU GOING TO DIE'. this scared me sooo much cause i saw it in the movie 'GO' a week later.
i somehow got in my bed and was lying there sooo sick. my heart was going soo fast so i mentally thought of time and how to slow it and everything actually slowed down my heart slowed..i no this casue i could hear it...i threw a pillow in the air and it was seriously in slow motion. even the music that i dont remember putting on was slowing down. then everything sped up again and was fast..i kept slowing it down casue it helped my heart beat...all this time there was a strange noise..like a steal factory poundin in my head that wouldnt stop.
i eventually passed out (it all lasted about 5 hours i think...but i dont know) and woke up in the morning. i told my dad i was sick with the flu and missed school. at about 1 i got a call from my friend Jonah who got sent home because he did shrooms and coke that day at school and passed out in A block and had a seizure.
DONT MIX THOSE 2 DRUGS...BAD COMBINATION

Permissions allow users to access certain features of a course or project worksite, depending on their roles, and on the decisions made by the site owner and the system administrator.
Roles are collections of permissions. Some roles allow users to simply access or read content, while other roles allow for advanced changes, such as adding participants, editing the site's content, and changing permissions for other roles.
When you create a worksite, or when one is created for you, you have the role with the most permissions and the broadest level of access. You can choose (within the limits established by the system administrator) which tools or functions (e.g., Forums, Schedule, Resources) you want the site to have. For many of these tools or functions, you can set permissions that allow or prevent users from seeing or performing certain tasks, depending on their roles.
For a summary of participant roles and how to find out what your role is, see Participant roles.
Roles may vary in name, depending on the application. However, in general, the creator of a project site, or the instructor of a course site, has full permissions, and can add or delete content within a worksite.
A user who joins an existing site has a more limited role. The permissions of this role allow for interaction in the site (e.g., creating Chat messages), but do not allow for advanced tasks (e.g., uploading files into Resources or creating assignments).
However, each implementation of the application will be different. System administrators can decide during implementation which roles to install, and which permissions these roles will have.
For help documentation about permissions and roles, see Permissions and roles.

I clicked this photo as I was walking through a busy market street in Bengaluru. The shops were just opening and the vendors were just starting to set up shop as I saw this old vendor laying out his stuff across the road from me. I clicked a couple of photos of his, across the street; throwing my camera settings to Black and White with increased Sharpness, for the effect.
I did play around a little with this photo in Adobe Lightroom and used a very nice preset for the White Balance and Lens Corrections. I switched over to Photoshop for the borders.
What I like about this photo is obviously the whole emotion of the photo and the varied graduated shades which are on display. The extra dark areas in this photo give a lot of depth to this photo. The textures on the door behind the vendor is one of my favorites & I'm glad this image has captured the different shades in the background alone.
Improvements I would like in this photo include a better visualization of the face and a closer look capture of the facial expressions. I should have made better use of the opportunity to try a few more shots from closer quarters.
