The package is designed to have fairly minimal requirements to build and use with your projects, but there are some. Currently, we support Linux based paltforms.
These are the base requirements to build and use the package (as described below):
The following documentation is correct to the day it was written. case you have problems with my instruction see the packages website for additional information.
All packages expect SNAP can be installed by running the following command from the directory you downloaded and unpacked the package
>./configure >make >make install >make check
To install SNAP just run the following command from the unpacked directory:
>make all
Since SNAP build is local you need to indicate its location for this package build. You do it using the config.site file. See non root users and only place the details that are relevant to SNAP.
The standard way to install packages when you don't have root privileges it to use the –prefix option when running the ./configure
>./configure --prefix=<path>
The above command will cause the package to be installed in the path given in the –prefix option. SNAP doesn't require any additional option and just type
>make all
From the directory you unpacked the source. Since you installed the packages in you desired location you need to list them in a file that will allow the package to find them and link with them and this is where config.site comes into play. After you installed Gtest (in ${GTEST_DIR}), SNAP (in ${SNAP_DIR}) and PROTOBUF (in ${PROTO_DEST}) create a file named config.site (I ommit Boost but if you need to install it just do the same as the others).
The file should contain the location of SNAP and Gtest:
CPPFLAGS="${CPPFLAGS} -I${GTEST_DIR}/include/ -I{SNAP_DIR}/snap-adv/ \ -I{SNAP_DIR}/snap-core/ -I{SNAP_DIR}/snap-exp/ -I{SNAP_DIR}/glib-core/ -I${PROTO_DEST}/include/" LIBS="${LIBS} {SNAP_DIR}/snap-core/Snap.o ${GTEST_DIR}/libgtest.a -lpthread" LDFLAGS="${LDFLAGS} -L${PROTO_DEST}/lib" PROTOC="${PROTO_DEST}/bin/protoc" PKG_CONFIG_PATH="${PROTO_DEST}/lib/pkgconfig/"
CPPFLAGS="${CPPFLAGS} -I/work/eng/eliavb/googletest-release-1.7.0/include/ -I/work/eng/eliavb/Snap-2.3/snap-adv/ -I/work/eng/eliavb/Snap-2.3/snap-core/ -I/work/eng/eliavb/Snap-2.3/snap-exp/ -I/work/eng/eliavb/Snap-2.3/glib-core/ -I/work/eng/eliavb/protobuf_install/include/" LIBS="${LIBS} /work/eng/eliavb/Snap-2.3/snap-core/Snap.o /work/eng/eliavb/googletest-release-1.7.0/libgtest.a -lpthread" LDFLAGS="${LDFLAGS} -L/work/eng/eliavb/protobuf_install/lib/" PROTOC="/work/eng/eliavb/protobuf_install/bin/protoc"
Case you enounter:
configure: error: Package requirements (protobuf >= 2.6.0) were not met: No package 'protobuf' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.
Try changing the package config env variable using the following command:
export PKG_CONFIG_PATH='${PROTO_DEST}/lib/pkgconfig/'
Case you encounter:
error while loading shared libraries: libprotobuf.so.9: cannot open shared object file: No such file or directory
Try:
export LD_LIBRARY_PATH="$LD_LIBRAY_PATH:${PROTO_DEST}/lib/"
After the file was created we need to set an env variable named CONFIG_SITE to point to the config.site:
>export CONFIG_SITE=$CONFIG_SITE:<path>/config.site
Suppose you placed the package in ${ADS_DIR} and want to install it in ${ADS_DEST}.
Enter to the ${ADS_DIR} and run:
>./configure --prefix=${ADS_DEST} >make >make install
Since this is not a root install we need to add the location of the proto lib
>export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${PROTO_DEST}/lib >make check
Suppose you placed the package in ${ADS_DIR}.
Enter to the ${ADS_DIR} and run:
>./configure >make >make install >make check


[gecode-users] Gecode 3.7.0 released
Guido Tack
tack at gecode.org
Tue Aug 30 12:34:22 CEST 2011
Dear all,
we are releasing a new version of Gecode:
Gecode 3.7.0
http://www.gecode.org
This release adds and improves quite a number of constraints (total lexicographic order for set variables, membership constraints for integer variables, counting constraints for integer variables using integer sets, range, roots, set element constraints for integer variables, number of values for integer variables). All of these constraints (and some more) are now also available in FlatZinc. Additionally, some fixes and improvements.
This release is an important milestone as Gecode now provides native implementations for all important constraints available in MiniZinc/FlatZinc.
The documentation of constraints in "Modeling and Programming with Gecode" now refers to the Global Constraint Catalog (for those constraints that are listed in the catalog). To give you an idea, Gecode 3.7.0 implements 74 constraints from the catalog and quite some additional not listed in the catalog.
The ones listed in the catalog implemented by Gecode are: abs_value, all_equal, alldifferent, alldifferent_cst, among, among_seq, among_var, and, arith, atleast, atmost, bin_packing, bin_packing_capa, circuit, clause_and, clause_or, count, counts, cumulative, cumulatives, decreasing, diffn, disjunctive, domain, domain_constraint, elem, element, element_matrix, eq, eq_set, equivalent, exactly, geq, global_cardinality, gt, imply, in, in_interval, in_intervals, in_relation, in_set, increasing, int_value_precede, int_value_precede_chain, inverse, inverse_offset, leq, lex, lex_greater, lex_greatereq, lex_less, lex_lesseq, link_set_to_booleans, lt, maximum, minimum, nand, neq, nor, not_all_equal, not_in, nvalue, nvalues, or, roots, scalar_product, set_value_precede, sort, sort_permutation, strictly_decreasing, strictly_increasing, sum_ctr, sum_set, xor.
On our web site, you find source packages, binary packages for Windows and Mac OS, and the full documentation.
Cheers,
Guido

Principal Components Analysis
Suppose you have samples located in environmental space or in species space (See Similarity, Difference and Distance). If you could simultaneously envision all environmental variables or all species, then there would be little need for ordination methods. However, with more than three dimensions, we usually need a little help. What PCA does is that it takes your cloud of data points, and rotates it such that the maximum variability is visible. Another way of saying this is that it identifies your most important gradients.
Let us take a hypothetical example where you have measured three different species, X1, X2, and X3:
In this example, it is possible (though it might be difficult) to tell that X1 and X2 are related to each other, and it is less clear whether X3 is related to either X1 or X2. Our job is to determine whether there is/are a hidden factor(s) or component(s) (or in the case of community ecology, gradient(s) ) along which our samples vary with respect to species composition.
The first stage in rotating the data cloud is to standardize the data by subtracting the mean and dividing by the standard deviation. Thus, the centroid of the whole data set is zero. We label these standardized axes S1, S2, and S3. The relative location of points remains the same:
From looking at the last two figures, one can already identify a gradient: from the lower left front to the upper right back. In other words, there appears to be an underlying gradient along which species 1 and species 2 both increase (In the language of Gauch (1982), species 1 and 2 both contain some "redundant" information. Let us now draw a line along this gradient:
Principal Components Analysis chooses the first PCA axis as that line that goes through the centroid, but also minimizes the square of the distance of each point to that line. Thus, in some sense, the line is as close to all of the data as possible. Equivalently, the line goes through the maximum variation in the data.
The second PCA axis also must go through the centroid, and also goes through the maximum variation in the data, but with a certain constraint: It must be completely uncorrelated (i.e. at right angles, or "orthogonal") to PCA axis 1.
If we rotate the coordinate frame of PCA Axis 1 to be on the X-axis, and PCA Axis 2 to be on the Y-axis, then we get the following diagram:
We can see that samples a, b, c, and d are at one extreme of species composition, and samples t, w, x, y, and z are at the other extreme. But there is a secondary gradient of species composition, from samples b, m, n, u, r and t up to samples l, q, w, and y. What is the underlying biology behind such a gradient? PCA, and any other indirect gradient analysis, is silent with respect to this question. This is where the biological interpretation comes in. The scientist needs to ask, what is special about the samples on the right which make them fundamentally different from those samples on the left? What is it about the biology of species 1 that makes it occur in the same locations as species 2?
We have only plotted two PCA Axes. However, there exist three axes in the data set (because there are three species). Why did we not plot the third? This is for two reasons:
How do we determine how many axes are worth interpreting? Ultimately, this is left up to the reasons for the investigation. But a big hint can be found with the eigenvalues. Every axis has an eigenvalue (also called latent root) associated with it, and they are ranked from the highest to the lowest. The first through the third eigenvalues for the first three axes in the above example are 1.8907, 0.9951, and 0.1142 respectively. These are related to the amount of variation explained by the axis. Note that the sum of the eigenvalues is 3, which is also the number of variables. It is usually typical to express the eigenvalues as a percentage of the total:
PCA Axis 1: 63% PCA Axis 2: 33% PCA Axis 3: 4%
In other words, our first axis explained or "extracted" almost 2/3 of the variation in the entire data set, and the second axis explained almost all of the remaining variation. Axis 3 only explained a trivial amount, and might not be worth interpreting.
How do we know which species contribute to which axes? We look at the component loadings (or "factor loadings"):
|
Species |
PCA 1 |
PCA 2 |
PCA 3 |
|
S1 |
0.9688 |
0.0664 |
-0.2387 |
|
S2 |
0.9701 |
0.0408 |
0.2391 |
|
S3 |
-0.1045 |
0.9945 |
0.0061 |
This means that the value of a sample along the first axis of PCA is 0.9688 times the standardized abundance of species 1 PLUS 0.9701 times the standardized abundance of species 2 PLUS -0.1045 times the standardized abundance of species 3.
We can interpret Axis 1 as being highly positively related to the abundances of species 1 and 2, and weekly negatively related to the abundance of species 3. Axis 2, on the other hand, is positively related to (and therefore correlated with) the abundance of all species, but mostly species 3. So the "gradient" reflected by Axis 2 is something which benefits species 3.
PCA is extremely useful when we expect species to be linearly (or even monotonically) related to each other. Unfortunately, we rarely encounter such a situation in nature. It is much more likely that species have a unimodal species response curve. That is, species usually peak in abundance at some intermediate part of environmental gradients (see also Explorations in Coenospace). Here is a hypothetical coenocline:
This means that species are non linearly related to each other. Let us now plot the abundance of the above three hypothetical species in species space:
However you describe the above cloud of points, it is certainly not a simple line or a plane. PCA would fail miserably with such a data set. In particular, PCA produces an artifact known as the Horseshoe Effect (similar to the Arch Effect), in which the second axis is curved and twisted relative to the first, and does not represent a true secondary gradient. Do note, however, that if we only sampled a small enough section of the gradient the data might be linear enough to allow the use of PCA.
For the Boomer Lake example given in Explorations in Coenospace, we have belt transects established along a lake shore, and a fairly well-defined zonation of plant species occurs as a function of distance from the water. When we perform a PCA on this data set, we get the following diagram:
This illustrates the horseshoe effect. The second axis is a curved distortion of the first axis. The second axis also has no easily understood biological meaning: there is no obvious reasons why samples 6, 7, and 8 should be at opposite ends of a gradient from samples 1, 2, and 9 through 12.
However, do recall that there was one predominant gradient: that of sample 1 through 12 (being a wetland to dryland gradient). However, PCA distorts this relationship with some incurving. Instead of going from sample 1 to 12 (as it should), the most extreme samples along PCA Axis 1 are samples 3 and 10.
The "toe" of the horseshoe can either be up or down; in this case it just happens to be up.
In this particular example, we are able to see the arch, and therefore might be able to conclude that the "real" extremes are quadrats 1 and 10,11, or 12. This is because there is only one clear gradient and the gradient is so strong. However, in many data sets, there may be more and weaker gradients, as well as more noise. Therefore, it would be very difficult to make sense of PCA.
Although PCA is often useful for the analysis of samples in species space, it is still quite appropriate for the analysis of samples in environmental space. This is because it is likely for most environmental variables to be monotonically related to underlying factors, and to each other. Also, PCA allows the use of variables which are not measured in the same units (e.g. elevation, concentration of nutrients, temperature, pH, etc.).

This is an experimental feature
Because this feature is still in development in some browsers, check the compatibility table for the proper prefixes to use in various browsers.
Summary
The hyphens
property tells the browser how to go about splitting words to improve the layout of text when line-wrapping.
Note: The rules defining how hyphenation is performed are not explicitly defined by the specification, so the exact hyphenation may vary from browser to browser.
Syntax
hyphens: none | manual | auto
Values
none
- Words are not broken at line breaks, even if characters inside the words suggest line break points. Lines will only wrap at whitespace.
manual
- Words are broken for line-wrapping only where characters inside the word suggest line break opportunities. See Suggesting line break opportunities for details.
auto
- The browser is free to automatically break words at appropriate hyphenation points, following whatever rules it chooses to use. Suggested line break opportunities, as covered in Suggesting line break opportunities, should be preferred over automatically selecting break points whenever possible.
Note: The auto
setting's behavior depends on the language being properly tagged so that the appropriate hyphenation rules can be selected. You must specify a language using the lang
HTML attribute in order to guarantee that automatic hyphenation is applied in the language of your choice.
Suggesting line break opportunities
There are two Unicode character that can be used to manually specify potential line break points within text:
- U+2010 (HYPHEN)
- The "hard" hyphen character indicates a visible line break opportunity. Even if the line is not actually broken at that point, the hyphen is still rendered.
- U+00AD (SHY)
- An invisible, "soft" hyphen. This character is not rendered visibly; instead, it suggests a place where the browser might choose to break the word if necessary. In HTML, you can use

to insert a soft hyphen.
Example
This CSS snippet creates three classes, one for each possible configuration of the hyphens
property.
p.none {
-moz-hyphens: none;
hyphens: none;
}
p.manual {
-moz-hyphens: manual;
hyphens: manual;
}
p.auto {
-moz-hyphens: auto;
hyphens: auto;
}
Take a look at the live example to see these configurations in action; resize the window while looking at them to see how hyphenation is handled in your browser.

When you define a class completely in PHP, you can add properties (member variables) to it. When you add member variables to a native C++ class however, you better use regular C++ member variables for that, instead of PHP variables. Native variables have an immensely better performance than PHP variables, and it would be insane to store integers or strings in Php::Value objects if you can store them in int's and std::string objects as well.
To access these member variables you could create getX() and setX() methods, or alternatively implement __get() and __set() methods if you want to make your native member variables look like public or protected properties.
I can not imagine that there is anyone in the world who would like to create a native class, with regular public PHP properties on it. But still, in this article we explain how you can do that.

The Init
Overview
The Init is the part of the code starting the logic behind playing a content.
Its code is written in the src/core/init
directory.
Every time you’re calling the API to load a new video, the init is called by it (with multiple options).
The Init then starts loading the content and communicate back its progress to the API through events.
+-----------+
1. LOAD VIDEO | | 2. CALLS
---------------> | API | -------------------+
| | |
+-----------+ |
^ v
| +--------------+
| 3. EMIT EVENTS | |
+------------------- | Init |
| |
+--------------+
During the various events happening on content playback, the Init will create / destroy / update various player blocks. Example of such blocks are:
-
Adaptive streaming management
-
DRM management
-
Manifest loading, parsing and refreshing
-
Buffer management
-
…
Usage
Concretely, the Init is a function which returns an Observable. This Observable:
-
will automatically load the described content on subscription
-
will automatically stop and clean-up infos related to the content on unsubscription
-
communicate on various streaming events through emitted notifications
-
throw in the case of a fatal error (i.e. an error interrupting playback)
Communication between the API and the Init
Objects emitted by the Observable is the only way the Init should be able to communicate with the API.
The API is then able to communicate back to the Init, either:
-
by Observable provided by the API as arguments when the Init function was called
-
by emitting through Subject provided by the Init, as a payload of one of its event
Thus, there is three ways the API and Init can communicate:
-
API -> Init: When the Init function is called (so a single time)
-
Init -> API: Through events emitted by the returned Observable
-
API -> Init: Through Observables/Subjects the Init function is in possession of.
Emitted Events
Events allows the Init to reports milestones of the content playback, such as when the content is ready to play.
It’s also a way for the Init to communicate information about the content and give some controls to the user.
For example, as available audio languages are only known after the manifest has been downloaded and parsed, and as it is most of all a user preference, the Init can emit to the API, RxJS Subjects allowing the API to “choose” at any time the wanted language.
Playback rate management
The playback rate (or speed) is updated by the Init.
There can be three occasions for these updates:
-
the API set a new Speed (
speed$
Observable). -
the content needs to build its buffer.
In which case, the playback speed will be set to 0 (paused) even if the API set another speed.
-
the content has built enough buffer to un-pause. The regular speed set by the user will be set again in that case.

The collection of UI widgets that are AngularJS directives. The goal was to develop components that will not require keyboard usage in order to enter data. This might be important if your web site is mobile oriented.
The main goal of the development was to come up with data and time entry widgets that would still be use-able at mobile applications by being reasonably user friendly and not taking too much space at the screen at the same time. You can use these components to enter date and time, mimic drop down list and some other UI elements without getting to the keyboard or using phone's native drop down list substitution widget.
At the moment this demo is being hosted at some low bandwidth environment, but hope it is still somehow use-able.
The toolkit is hosted at GitHub
This section is using Bootstrap for element styling.
This section does not look sleek, but demonstrates the components are not dependent on anything but AngularJS and can be styled independently per your project's requirements.

#include <db.h>int db_appexit(DB_ENV *dbenv);
The db_appexit function closes the initialized Berkeley DB subsystems, freeing any allocated resources and closing any underlying subsystems.
In multi-threaded applications, only a single thread may call db_appexit.
The db_appexit function returns the value of errno on failure, and 0 on success.
The db_appexit function may fail and return errno for any of the errors specified for the following Berkeley DB and C library functions: free(3), lock_close, log_close, memp_close, memset(3), strlen(3), and txn_close.


Dolores O'Riordan would be 'immensely proud' of Grammy nomination
by By Steve NevilleThe Cranberries have said late lead singer Dolores O'Riordan would have been "immensely proud" of being Grammy nominated.
The band's album, In The End, was nominated in the Best Rock Album category yesterday.
The album is the eight and final album from the Limerick band and the first to be released after O'Riordan's death.
The iconic singer - who passed away in 2018 - had vocals feature on the album posthumously.
Reacting to the Grammy nomination, the band said on social media that they were honoured.
"We are humbly honoured with the news that our final album 'In the End' has been nominated for a 2020 Grammy in the category of Best Rock Album.
"It’s a fitting tribute to Dolores and her truly amazing talents. She would be immensely proud."
Speaking yesterday, the singer's mum Eileen O’Riordan said: “Dolores would be so happy with this, she put her heart and soul into her songs and music.
“For us as her family it’s kind of bittersweet, we’re immensely proud yet saddened that she isn’t here to witness and enjoy this, although I feel that she is in spirit.”
Guitarist Noel Hogan added: "We wanted to finish this album for our dear friend and band mate Dolores.
"It’s a tribute to her, the band and our fans for the past thirty years. Being honoured with this Grammy nomination has made this whole process even more special."
The Cranberries will be up against Bring Me The Horizon, Cage The Elephant, I Prevail and Rival Sons in their category.

The action list item lets the user trigger actions directly from a list item This component makes use of
list-item directive present in fundamental-ngx/core and has additional
enhancements on top of it.
Platform specific enhancements:
-
Action-List-item is implemented as Angular component to hide complexity of dealing with HTML in order to
deliver high-order component.
- Alignment of sub element title is abstracted.
- Enhanced support for accessibility which covers access by keyboard, mouse and touch.
- Enhanced compatibility with screen readers.
- Supports both imperative and declarative way of accepting the items for all the list variants.
