Olivier Ntcham speaks on international future as Celtic midfielder reveals chat with Cameroon boss
by Kathleen OatesOlivier Ntcham has revealed he turned down an approach from Cameroon to represent the Indomitable Lions.
The 23-year-old, who was born in France 11 miles from the capital Paris, has represented Les Bleus at Under-21 level but qualifies for Cameroon through his parents.
Speaking to the Celtic View, the former Manchester City youngster said: “The Cameroon manager [Toni Conceição] approached me last year about [representing the team at senior level].
"We talked, and I told him my targets.
"We spoke again recently when I was preparing for the Europa League games but I told him international football was not my priority right now.
"I told him I had to make sure I got back in the Celtic team first. Once I did that, then I can think about football."
Ntcham, who scored a stunning late winner for the Hoops in Rome against Lazio, has been capped 20 times by France Under-21s and hasn't given up hope of receiving a call-up to the senior squad.
He continued: "My parents are both from Cameroon but I’ve never been there myself. I think my parents would be happier if I played with France.”

Golang: Using SSH instead of HTTPS to git clone packages
Published: July 20, 2020
The Problem
By default go get
clones git repository using https
. This works for most people. go get
will return 0
, and they'll carry on with their project. For me it wasn't quite as simple. Whenever I'd run go get <package>
I'd be greeted with the following error message after staring at a blank cursor for what felt like an eternity:
[eli@host]$ go get github.com/example/example
# cd .; git clone -- https://github.com/example/example /home/eli/go/src/github.com/example/example
Cloning into '/home/eli/go/src/github.com/example/example'...
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: the remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
package github.com/example/example: exit status 128
The smoking gun:
curl 18 transfer closed with outstanding read data remaining
This meant the TCP connection to https://github.com/example/example was prematurely disconnected.
The Cause
It's sorta obvious but I'll say it anyways, libcurl
was timing out due to shotty internet.
You see, I have soul-crushingly slow satellite internet. Unlike most people in the developed world I'm dependant on a ~500Kbps connection with 800-1000ms ping. Over the years this has led to numerous problems and headaches. Add this to the list.
The Solution
Instead of using cloning repostories over https
lets use ssh
. This problem has already been solved, let's not reinvent the wheel, ssh
keeps the connection alive. When given the choice I clone via ssh
so this was the natural choice. In hindsight it's why I've had little to no trouble cloning larger git repositories.
All we have to do is amend our git config file to redirect github https
clones with their ssh
counterpart.
git config --global --add url."git@github.com:".insteadOf "https://github.com/"
Note: --global
specifies that we write to $HOME/.gitconfig
if this is undesirable we can write to the repositories local .git/config
This is the default behavior of git config
git config --add url."git@github.com:".insteadOf "https://github.com/"
Final Thoughts
Down the road I might run into a hiccup since I'm changing the default behavior of git, but I don't see much of a problem since I'm changing the behavior on a per project basis. Worse case I strip the line from .git/config

set varName ?value?

The fundamental construct in [incr Tcl] is the class definition. Each class acts as a template for actual objects that can be created. The class itself is a namespace which contains things common to all objects. Each object has its own unique bundle of data which contains instances of the "variables" defined in the class definition. Each object also has a built-in variable named "this", which contains the name of the object. Classes can also have "common" data members that are shared by all objects in a class.
Two types of functions can be included in the class definition. "Methods" are functions which operate on a specific object, and therefore have access to both "variables" and "common" data members. "Procs" are ordinary procedures in the class namespace, and only have access to "common" data members.
If the body of any method or proc starts with "@", it is treated as the symbolic name for a C procedure. Otherwise, it is treated as a Tcl code script. See below for details on registering and using C procedures.
A class can only be defined once, although the bodies of class methods and procs can be defined again and again for interactive debugging. See the body and configbody commands for details.
Each namespace can have its own collection of objects and classes. The list of classes available in the current context can be queried using the "itcl::find classes" command, and the list of objects, with the "itcl::find objects" command.
A class can be deleted using the "delete class" command. Individual objects can be deleted using the "delete object" command.
The class definition is evaluated as a series of Tcl statements that define elements within the class. The following class definition commands are recognized:
The order of baseClass names in the inherit list affects the name resolution for class members. When the same member name appears in two or more base classes, the base class that appears first in the inherit list takes precedence. For example, if classes "Foo" and "Bar" both contain the member "x", and if another class has the "inherit" statement:
inherit Foo Bar
Before the body is executed, the optional init statement is used to invoke any base class constructors that require arguments. Variables in the args specification can be accessed in the init code fragment, and passed to base class constructors. After evaluating the init statement, any base class constructors that have not been executed are invoked automatically without arguments. This ensures that all base classes are fully constructed before the constructor body is executed. By default, this scheme causes constructors to be invoked in order from least- to most-specific. This is exactly the opposite of the order that classes are reported by the info heritage command.
If construction is successful, the constructor always returns the object name-regardless of how the body is defined-and the object name becomes a command in the current namespace context. If construction fails, an error message is returned.
When an object is destroyed, all destructors in its class hierarchy are invoked in order from most- to least-specific. This is the order that the classes are reported by the "info heritage" command, and it is exactly the opposite of the default constructor order.
If the args list is specified, it establishes the usage information for this method. The body command can be used to redefine the method body, but the args list must match this specification.
Within the body of another class method, a method can be invoked like any other command-simply by using its name. Outside of the class context, the method name must be prefaced an object name, which provides the context for the data that it manipulates. Methods in a base class that are redefined in the current class, or hidden by another base class, can be qualified using the "className::method" syntax.
If the args list is specified, it establishes the usage information for this proc. The body command can be used to redefine the proc body, but the args list must match this specification.
Within the body of another class method or proc, a proc can be invoked like any other command-simply by using its name. In any other namespace context, the proc is invoked using a qualified name like "className::proc". Procs in a base class that are redefined in the current class, or hidden by another base class, can also be accessed via their qualified name.
If the optional init string is specified, it is used as the initial value of the variable when a new object is created. Initialization forces the variable to be a simple scalar value; uninitialized variables, on the other hand, can be set within the constructor and used as arrays.
The optional config script is only allowed for public variables. If specified, this code fragment is executed whenever a public variable is modified by the built-in "configure" method. The config script can also be specified outside of the class definition using the configbody command.
If the optional init string is specified, it is used as the initial value of the variable. Initialization forces the variable to be a simple scalar value; uninitialized variables, on the other hand, can be set with subsequent set and array commands and used as arrays.
Once a common data member has been defined, it can be set using set and array commands within the class definition. This allows common data members to be initialized as arrays. For example:
itcl::class Foo { common boolean set boolean(true) 1 set boolean(false) 0 }
Once a class has been defined, the class name can be used as a command to create new objects belonging to the class.
If objName contains the string "#auto", that string is replaced with an automatically generated name. Names have the form className<number>, where the className part is modified to start with a lowercase letter. In class "Toaster", for example, the "#auto" specification would produce names like toaster0, toaster1, etc. Note that "#auto" can be also be buried within an object name:
fileselectiondialog .foo.bar.#auto -background red
If a single option of the form "-varName" is specified, then this method returns the information for that one variable.
Otherwise, the arguments are treated as option/value pairs assigning new values to public variables. Each variable is assigned its new value, and if it has any "config" code associated with it, it is executed in the context of the class where it was defined. If the "config" code generates an error, the variable is set back to its previous value, and the configure method returns an error.
itcl::class Toaster { variable crumbs 0 method toast {nslices} { if {$crumbs > 50} { error "== FIRE! FIRE! ==" } set crumbs [expr $crumbs+4*$nslices] } method clean {} { set crumbs 0 } }
itcl::class SmartToaster { inherit Toaster method toast {nslices} { if {$crumbs > 40} { clean } return [Toaster::toast $nslices] } }
itcl::class SmartToaster { inherit Toaster method toast {nslices} { if {$crumbs > 40} { clean } return [chain $nslices] } }
Class definitions need not be loaded explicitly; they can be loaded as needed by the usual Tcl auto-loading facility. Each directory containing class definition files should have an accompanying "tclIndex" file. Each line in this file identifies a Tcl procedure or [incr Tcl] class definition and the file where the definition can be found.
For example, suppose a directory contains the definitions for classes "Toaster" and "SmartToaster". Then the "tclIndex" file for this directory would look like:
# Tcl autoload index file, version 2.0 for [incr Tcl] # This file is generated by the "auto_mkindex" command # and sourced to set up indexing information for one or # more commands. Typically each line is a command that # sets an element in the auto_index array, where the # element name is the name of a command and the value is # a script that loads the command. set auto_index(::Toaster) "source $dir/Toaster.itcl" set auto_index(::SmartToaster) "source $dir/SmartToaster.itcl" The auto_mkindex command is used to automatically generate "tclIndex" files.
C procedures can be integrated into an [incr Tcl] class definition to implement methods, procs, and the "config" code for public variables. Any body that starts with "@" is treated as the symbolic name for a C procedure.
Symbolic names are established by registering procedures via Itcl_RegisterC(). This is usually done in the Tcl_AppInit() procedure, which is automatically called when the interpreter starts up. In the following example, the procedure My_FooCmd() is registered with the symbolic name "foo". This procedure can be referenced in the body command as "@foo".
int Tcl_AppInit(interp) Tcl_Interp *interp; /* Interpreter for application. */ { if (Itcl_Init(interp) == TCL_ERROR) { return TCL_ERROR; } if (Itcl_RegisterC(interp, "foo", My_FooCmd) != TCL_OK) { return TCL_ERROR; } }
This scheme provides a natural migration path for code development. Classes can be developed quickly using Tcl code to implement the bodies. An entire application can be built and tested. When necessary, individual bodies can be implemented with C code to improve performance.


You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... and only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.
Do you see any Teletubbies in here? Do you see a slender plastic tag clipped to my shirt with my name printed on it? Do you see a little Asian child with a blank expression on his face sitting outside on a mechanical helicopter that shakes when you put quarters in it? No? Well, that's what you see at a toy store. And you must think you're in a toy store, because you're here shopping for an infant named Jeb.Like you, I used to think the world was this great place where everybody lived by the same standards I did, then some kid with a nail showed me I was living in his world, a world where chaos rules not order, a world where righteousness is not rewarded. That's Cesar's world, and if you're not willing to play by his rules, then you're gonna have to pay the price.

Best-selling author Lee Child is applying for Irish passport because of Brexit
The novelist says he is “not a huge fan of Britain”.
by Press AssociationBRITISH WRITER LEE Child, creator of the Jack Reacher thriller series, is reportedly applying for an Irish passport due to Brexit.
Child, whose real name is James Grant, is a best-selling author of thriller novels, who has sold more than 100 million books.
He lives between the UK and the US but is entitled to an Irish passport as his father was born in Belfast.
The author said he wants an Irish passport to avoid the possibility of post-Brexit travel restrictions in Europe.
“I haven’t got the passport yet but I will do very soon, it feels like I’m cheating to be honest as I will get in the back door,” Child told the Irish Times.
He was speaking in Berlin as part of a European “Friendship Tour”, where Child and fellow British authors Kate Mosse, Jojo Moyes and Ken Follett spoke out against Brexit.
I am not a huge fan of Britain, even though I was born there.
“It’s a silly and frustrating country, which is why I moved to America,” Child said.
He also criticised Prime Minister Boris Johnson, portraying him as an elitist:
If he had gone to my school he would not now be Prime Minister.
The author’s pen name “Lee” comes from a family joke about a heard mispronunciation of the name of Renault’s Le Car, as “Lee Car”. The surname “Child” places his books on bookstore and library shelves between crime fiction greats Raymond Chandler and Agatha Christie.
Child’s new book, Blue Moon, has just been released.


‘Healthy’ protein bars not as good as we believe
Eating high-protein bars as a “healthy” alternative to other snack foods is not as beneficial as many of us think, new research shows.
High-protein bars, on average, are comparable to a standard chocolate bar in their calorie, fat, saturated fat, and salt content, according to analysis by Safefood.
Safefood surveyed 83 high-protein snack foods and drinks for sale in major supermarkets, discount and convenience stores in Cork and Belfast between March and April, 2018. These foods included protein bars, yoghurts, yoghurt-style products, and milk drinks.
The survey found:
- 38% of protein bars contain chocolate as main ingredient;
- 77% are high in saturated fat;
- 1 in 3 people perceive them as being “healthy”;
- The average bar size was 55g with an average price of €2.27, costing up to €3 each.
Dr Catherine Conlon, Safefood’s director of human health & nutrition, said people would be better off “sticking to natural sources of protein in their diet, which tend to be much healthier”.
“And if you need a source of protein as a snack, alternatives like some nuts, a small glass of milk or a yoghurt is the way to go.”
Safefood said there is “no evidence that population protein intakes are low”.

Leeks are an underrated vegetable. When steamed they have a lovely sweet flavour. Perfect with a boiled egg and garlicky mushrooms. This is designed to be a low cost recipe.
Place the eggs into a pan of boiling water. Boil for eight minutes exactly, then drain and cool under cold running water. Peel the eggs and set them aside.
Trim the very tops off the leeks and then cut two-thirds of the way down. Discard any of the coarse outer leaves of the upper two-thirds, cut in half lengthways and horizontally and separate the inner green stems into strips.
Cut the lower white part of the leek into rounds. Steam the white round and green strips in a steamer placed over salted boiling water for four minutes, or until tender.
Run the leeks under cold water to cool. Squeeze them out if they are at all watery.
Meanwhile, heat a small frying pan and add a tablespoon of the oil. Once hot, add the sliced mushrooms to the pan with a pinch of salt. Cook over a medium heat for 4-5 minutes, or until tender and lightly golden-brown. Add the garlic and fry for another minute.
Whisk the remaining olive oil together with the vinegar and mustard in a small bowl to make a dressing. Taste and season as necessary. Cut the peeled eggs into wedges. Put the cooled leeks in a bowl and top them with the eggs. Season with salt and pepper
Dress the egg and leek with the dressing. Taste and adjust the seasoning if needed. Serve with the mushrooms and baguette.


Linux looks for commands in its PATH. You can see the value of your PATH with this in a terminal: echo $PATH You can change PATH with PATH=/whatever/Your/New/Path:/or/:PathsAre You can add to your current PATH with PATH=$PATH:/your/additions or PATH=/your/additions/:$PATH and then EXPORT PATH The first adds to the end of the current path and the latter puts before the current path. Linux searches the path from the beginning til it finds the command or exhausts the path. If we already have a java, javac or other command in our PATH and we want to replace with a different, then we want to put our additions at the beginning of the PATH. We can also personalize our PATH in $HOME/.bash_profile If we use a command like which java Linux will search our PATH until it finds it and will return the path to the command or it will tell us the command is not in our PATH
UBUNTU USERS!
As of Ubuntu 10.04, the .bash_profile is NOT being used. It doesn't run at startup, so the PATH and CLASSPATH aren't being changed. You will need to: sudo gedit .xprofile and add this into the file: . ~/.bash_profile Now edit the .bash_profile: sudo gedit .bash_profile The end result of the .bash_profile should look something like this: PATH=$HOME/Java/bin:$HOME/bin:$HOME/Java/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games CLASSPATH=.:$HOME/MySQLConJava/connector.jar:/home/jacob/Tomcat/lib/servlet-api.jar:/home/jacob/Tomcat/lib/mysql-connector-java-5.1.14-bin.jar export PATH export CLASSPATH Now you will need to log off, and log back on. The new PATH and CLASSPATH will now be used.

Maruti Suzuki Ertiga scores three stars in 2019 Global NCAP crash test
by Aditya JadhavThe Maruti Suzuki Ertiga is one of the cars tested by Global NCAP this year and the MPV scored a three-star rating in the sixth round of the 2019 crash test. The head and neck protection for the driver was rated as good. The chest protection for the passenger was good too, however, the driver chest protection was marginal.
The structure of the frame was deemed borderline unstable, which could be a concern as the Ertiga was recently upgraded to the second generation adopting the Heartect platform. The footwell of the Ertiga was termed 'Unstable' as well and the displacement of the pedals showed risk to the driver's legs. The chest protection for the driver and the passenger received marginal protection although the passenger pretensioner failed to work properly.
The Ertiga gets ISOFIX mounts as standard but for child occupant safety, the MPV received poor ratings for an 18-month-old dummy with CRS (Child Restraint System / Child Seat) installed facing forward. CRS mounted rearward is said to be a better practice. It was also brought to notice that the Ertiga does not offer a three-point seat belt for all occupants.
The Ertiga is priced between Rs 7.54 - 11.20 lakh ex-showroom Mumbai. The MPV gets two engine options - 1.5-litre petrol and 1.5-litre diesel. The petrol is mated to a 5-speed manual, whereas the diesel gets a 6-speed manual. The petrol engine comes with an optional automatic transmission.

Functionality for rendering Ambisonics data by panning it to standard speaker layouts.
Ambisonics is a powerful format for encoding 3D sound fields, and exchanging them. Phonon can encode data into Ambisonics using the Panning Effect: to spatialize a sound source and create an Ambisonics track, use the Panning Effect with outputFormat.channelLayoutType
set to IPL_CHANNELLAYOUTTYPE_AMBISONICS
.
Phonon can also decode and render Ambisonics data, using panning. This involves approximating the sound field as if it were generated by sound coming from each speaker.
Ambisonics also allows 3D audio rendering in VR to be significantly accelerated: instead of applying object-based binaural rendering to each source individually, the sources can be encoded into Ambisonics first, then mixed, and finally the mix can be rendered using Ambisonics binaural rendering. This saves CPU cycles, at the cost of some spatialization accuracy.

Summary
JDepend traverses Java class file directories and generates design quality metrics for each Java package. JDepend allows you to automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability to manage package dependencies effectively.
JDepend traverses Java class file directories and generates design quality metrics for each Java package, including:
The number of concrete and abstract classes (and interfaces) in the package is an indicator of the extensibility of the package.
The number of other packages that depend upon classes within the package is an indicator of the package's responsibility.
The number of other packages that the classes in the package depend upon is an indicator of the package's independence.
The ratio of the number of abstract classes (and interfaces) in the analyzed package to the total number of classes in the analyzed package.
The range for this metric is 0 to 1, with A=0 indicating a completely concrete package and A=1 indicating a completely abstract package.
The ratio of efferent coupling (Ce) to total coupling (Ce + Ca) such that I = Ce / (Ce + Ca). This metric is an indicator of the package's resilience to change.
The range for this metric is 0 to 1, with I=0 indicating a completely stable package and I=1 indicating a completely instable package.
The perpendicular distance of a package from the idealized line A + I = 1. This metric is an indicator of the package's balance between abstractness and stability.
A package squarely on the main sequence is optimally balanced with respect to its abstractness and stability. Ideal packages are either completely abstract and stable (x=0, y=1) or completely concrete and instable (x=1, y=0).
The range for this metric is 0 to 1, with D=0 indicating a package that is coincident with the main sequence and D=1 indicating a package that is as far from the main sequence as possible.
Package dependency cycles are reported along with the hierarchical paths of packages participating in package dependency cycles.
Before using JDepend, it is important to understand that "good" design quality metrics are not necessarily indicative of good designs. Likewise, "bad" design quality metrics are not necessarily indicative of bad designs. The design quality metrics produced by JDepend should not be used as yard sticks by which all designs are measured.
The design quality metrics produced by JDepend are intended to be used by designers to measure the designs they create, understand those designs, and automatically check that the designs exhibit expected qualities while undergoing continuous refactoring. Refactoring will undoubtedly lead to some adjustment of these metrics as the shape of the design changes.
Measure Design Quality
The quality of a design can be measured in part by quantifying its degrees of extensibility, reusability, and maintainability. These qualities are all influenced by the inter-package dependencies of the design. Designs are more extensible when they are independent of implementation details, allowing them to adapt to new implementations without internal modification or breaking their existing contracts. This same independence tends to increase the reuse potential of portions of the design. Independent portions of the design containing high-level abstractions can be extracted from portions containing implementation details.
The maintainability of a design is improved when changes can easily be made without propagating to other parts of the system. JDepend allows you to automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability to effectively manage and control package dependencies.
Invert Dependencies
The goal of using JDepend is to ultimately invert package dependencies such that low-abstraction packages depend upon high-abstraction packages. This inversion of dependencies allows the high-abstraction packages to be reused independently while being extensible to an open set of implementations. In general, dependencies upon stable packages are desirable, while dependencies upon instable packages are undesirable. JDepend allows dependencies to be iteratively examined and refactored as an integral part of software design and development.
Foster Parallel, Extreme Programming
Packages that are stable should be the centerpieces of a loosely coupled application so the speed of the development team is not adversely affected by the propagation of software changes. Stable packages form design-by-contract facades to other subsystems, allowing teams to develop in parallel at an extreme pace. Moreover, by measuring the software design quality, the overall impact of proposed software changes can be accurately estimated. JDepend allows teams to identify and use desirable dependencies in the system and avoid those dependencies that cause changes to ripple throughout the system.
Isolate Third-Party Package Dependencies
Third-party package dependencies can be easily identified and isolated by examining the afferent couplings to those packages. Once the dependency on these third-party packages has been measured with JDepend, the dependency can be managed by effectively designing abstract and stable packages that encapsulate the third-party package implementation details.
Package Release Modules
Packages that are cohesive and independent can be released as autonomous modules with their own release schedules and version numbers. Single packages, or groups of related packages collaborating in a framework, that are candidates for independent release can be harvested by evaluating their design quality metrics using JDepend.
Identify Package Dependency Cycles
Packages participating in a package dependency cycle are in a deadly embrace with respect to reusability and their release cycle. Package dependency cycles can be easily identified by reviewing the textual reports of dependency cycles. Once these dependency cycles have been identified with JDepend, they can be broken by employing various object-oriented techniques.

JDepend provides a graphical, textual, and XML user interface to visualize Java package metrics, dependencies, and cycles.
Graphical UI
The graphical user interface displays a hierarchical tree for both the afferent and efferent couplings of each analyzed Java package.
To run JDepend with the graphical user interface, use the following syntax:
java jdepend.swingui.JDepend [-components <components>] <directory> [directory2 [directory 3] ...]
For example, to analyze all the Java class files in the
$JDEPEND_HOME/build
directory, use:
java jdepend.swingui.JDepend $JDEPEND_HOME/build
Textual UI
The textual user interface displays detailed metrics, dependencies, and cycles for each analyzed Java package. For the convenience of importing these metrics into other applications, the summary section contains comma-separated metrics for each Java package. Alternatively, the XML user interface can be used for easier integration with other tools.
To run JDepend with the textual user interface, use the following syntax:
java jdepend.textui.JDepend [-components <components>] [-file <output file>] <directory> [directory2 [directory 3] ...]
For example, to analyze all the Java class files in the
$JDEPEND_HOME/build
directory, use:
java jdepend.textui.JDepend $JDEPEND_HOME/build
Alternatively, the text report can be written to file using:
java jdepend.textui.JDepend -file report.txt $JDEPEND_HOME/build
Example output from the
textual UI shows the analysis of the sample application, an example
electronic payment framework. The relevant source for the sample
application is distributed in
$JDEPEND_HOME/sample
.
XML UI
The XML user interface displays detailed metrics, dependencies, and cycles for each analyzed Java package in an XML format for easier integration with other tools.
To run JDepend with the XML user interface, use the following syntax:
java jdepend.xmlui.JDepend [-components <components>] [-file <output file>] <directory> [directory2 [directory 3] ...]
For example, to analyze all the Java class files in the
$JDEPEND_HOME/build
directory, use:
java jdepend.xmlui.JDepend $JDEPEND_HOME/build
Alternatively, the XML report can be written to file using:
java jdepend.xmlui.JDepend -file report.xml $JDEPEND_HOME/build
Example output from the
XML UI shows the analysis of the sample application, an example
electronic payment framework. The relevant source for the sample
application is distributed in
$JDEPEND_HOME/sample
.
You can then transform the XML format into a format of your liking.
For example, David Bock contributed an XSL stylesheet that transforms
the JDepend XML output into a Graphviz dot file format. David's stylesheet is
distributed with JDepend in the contrib/jdepend2dot.xsl
file.
To create a sample Graphviz file, use:
ant jdepend-to-graphviz
This will create a docs/jdepend-report.dot
file. If
you have Graphviz installed, you can then convert that .dot file
into a .png file using:
dot -Tpng -o jdepend.png jdepend.dot
The graphical user interface displays the afferent and efferent couplings of each analyzed Java package, presented in the familiar Java Swing tree structure.
Figure 1 shows the analysis of the sample application, an example
electronic payment framework. The relevant source for the sample
application is distributed in $JDEPEND_HOME/sample
.
Figure 1 (Click to view full-scale)
The root of each tree displays a branch for each analyzed Java package, annotated with the following metrics:
For organizational purposes, package metrics are only displayed at the root of each tree. For convenience, selecting any node of the tree displays the currently selected package's metrics in the status bar.
Efferent Couplings
The top tree displays the efferent couplings of each analyzed Java package. Branches of the tree can be opened up to explore packages that the currently selected package depends upon (Figure 2).
Figure 2 (Click to view full-scale)
For the epayment.adapters
package, we see that it depends
upon 4 other packages:
the com.abc.epayment
, com.xyz.epayment
,
epayment.framework
, and the epayment.response
packages. Furthermore, it's completely concrete (A=0) and completely
instable (I=1). This balance earns it a spot squarely on the main
sequence (D=0). We can conclude from these metrics that dependencies on
this package are undesirable because it's both dependent and irresponsible.
It's sensitive to modifications made to any of it's efferent couplings and
not accountable to any other package. Therefore, it's important that other
packages in the system not become dependent on this package, as they'll in turn
become fragile by any modifications made to the details of the
epayment.adapters
package and its dependencies. As a concrete
package, it's not capable of being extended without being modified.
For the epayment.framework
package, we see that it does
not depend on any other packages in the application (Ce=0). However,
it is responsible to every other package (Ca=5) while exhibiting a
high degree of abstractness (A=0.83) and stability (I=0). While not
completely balanced, this package is very near the main sequence
(D=0.17). We can conclude from these metrics that dependencies on
this package are desirable because it's both independent and
responsible. It's abstractness also indicates that it's capable of
being extended to accommodate new implementations without being
modified.
Packages that were imported, but not analyzed, are not shown in the efferent dependency tree. Third-party software packages that weren't analyzed, for example, will not be shown in the efferent tree, as their efferent dependencies are not available.
Afferent Couplings
The bottom tree displays the afferent couplings of each analyzed Java package. Branches of the tree can be opened up to explore packages that use the currently selected package (Figure 3).
Figure 3 (Click to view full-scale)
For the epayment.adapters
package, we see that it is not
used by any other package in the application. This confirms our
observations of the efferent dependency tree.
For the epayment.framework
package, we see that it's used
by all the other user-defined packages in the framework. However, it
does not have any efferent couplings (Ce=0) and exhibits a high degree
of abstractness (A=0.83) and stability (I=0). This is a requirement
of a software framework - we want it to be heavily used, thereby
making it very responsible to its clients, yet be highly abstract to
allow extensibility without modification.
For the com.abc.epayment
package, a third-party software
package, we see that it's used by the epayment.adapters
package. There are no metrics displayed for this package however, as
it's a third-party package that was not analyzed by JDepend. It was
imported by a user-defined package (epayment.adapters
),
so it is shown in the afferent dependency tree.
Using the afferent dependency tree, it's easy to identify which user-defined packages are dependent upon third-party software packages.
Package dependency cycles are best observed using the textual or XML user interface. In general, all packages dependencies that intersect a dependency cycle are reported. This includes packages directly participating in a cycle and packages that depend on packages directly participating in a cycle.
The intent is to identify sets of packages that must be reused and released together. To break reported cycles, focus on those packages directly participating in a cycle.
Here's an example of a two-package cycle, as reported by the textual UI:
com.xyz.ejb | | com.xyz.servlet |-> com.xyz.ejb
This indicates that the com.xyz.ejb
package depends on
the
com.xyz.servlet
package, which in turn depends on the
com.xyz.ejb
package. These two package must be released and
reused together.
Here's an example of a package that depends on the two-package cycle described above, as reported by the textual UI:
com.xyz.client | |-> com.xyz.ejb | com.xyz.servlet |-> com.xyz.ejb
This indicates that the com.xyz.client
package depends on
the com.xyz.ejb
package, which in turn forms a cyclic
dependency with the com.xyz.servlet
package.
The com.xyz.client
package itself isn't part of the
cycle, but since it depends on a package in the cycle, it can't be
reused/released without it.
JDepend can be customized by using command-line options and/or by
creating a jdepend.properties
file in the user's home
directory or any directory in the classpath.
Components
JDepend can calculate metrics and dependencies for components: packages that contain one or more sub-packages.
For example, given the following package hierarchy:
com.xyz.package_a.subpackage_a com.xyz.package_a.subpackage_b com.xyz.package_a.subpackage_c com.xyz.package_b.subpackage_a com.xyz.package_b.subpackage_b
Assume you want to collect metrics and dependencies for the
com.xyz.package_a
and com.xyz.package_b
packages, but not for any of their contained packages. For example,
if there is a dependency from com.xyz.package_a.subpackage_a
to com.xyz.package_b.subpackage_b
, then you want it
to be reported as a dependency from com.xyz.package_a
to com.xyz.package_b.subpackage_b
.
To do that, use the -components
command-line argument:
java jdepend.textui.JDepend -components com.xyx.package_a,com.xyz.package_b /path/to/classes
Note that if component packages are named using the
-components
option, then no other packages
are reported.
Package Filters
JDepend will ignore all package names specified as values to the
ignore
property name prefix in the
jdepend.properties
file. By default, no packages are filtered.
The following example jdepend.properties
file will ignore
all package names prefixed by java
, javax
,
sun
, com.sun
, and the package
com.xyz.tests
:
ignore.java=java.*,javax.* ignore.sun=sun.*,com.sun.* ignore.tests=com.xyz.tests
Packages can also be filtered programmatically by creating a
PackageFilter
instance defining the filters and
then passing it to the JDepend
constructor.
The following example will ignore all package names prefixed by
java
and javax
, in addition to any
package filters specified in an existing
jdepend.properties
file:
PackageFilter filter = new PackageFilter(); filter.addPackage("java.*"); filter.addPackage("javax.*"); JDepend jdepend = new JDepend(filter);
The following example will ignore only the package names prefixed
by java
and javax
, regardless of any package
filters specified in an existing
jdepend.properties
file:
Collection filters = new ArrayList(); filters.add("java.*"); filters.add("javax.*"); PackageFilter filter = new PackageFilter(filters); JDepend jdepend = new JDepend(filter);
Volatility
Packages that are not expected to change can be specifically
configured with a volatility (V) value in the
jdepend.properties
file.
V can either be 0 or 1. If V=0, meaning the package is not at
all subject to change, then the package will automatically fall
directly on the main sequence (D=0). If V=1, meaning that the
package is subject to change, then the distance from the main
sequence is not affected. By default, all packages are
configured with V=1.
For example, a package like java.lang
is generally not
volatile. That is, for all practical purposes this package is
maximally stable. Creating dependencies on it is not cause for
concern. Thus, if you include this package in analysis, it's best to
set its V=0.
The following example jdepend.properties
file will set
the java.lang
package's volatility to 0:
java.lang=0
Volatility can also be programmatically set on individual packages
prior to analysis by creating a package instance, setting its
volatility, then registering it with the
JDepend
instance before analysis.
The following example sets V=0 for the java.lang
package:
JavaPackage javaLang = new JavaPackage("java.lang"); javaLang.setVolatility(0); // or JavaPackage javaLang = new JavaPackage("java.lang", 0); JDepend jdepend = new JDepend(); jdepend.addDirectory("/path/to/classes"); jdepend.addPackage(javaLang); jdepend.analyze();
Wildcards are not supported for configuring sets of packages with a volatility value.
Inner Classes
By default, inner classes are analyzed.
The following example jdepend.properties
file will
disable analyzing inner classes:
analyzeInnerClasses=false
In the spirit of automation, metrics can be automatically collected by JDepend so that they never go stale or require visual inspection. As the software evolves through refactorings, the design quality test cases can be run as a sanity check to ensure that the design has not formed too many undesirable dependencies.
Tolerances for any collected metrics (e.g., the distance from the main sequence (D)) can be codified in a JUnit test case that automatically checks the metrics for conformance to a desired result and provides immediate visual feedback. Tests can also be written to fail if any package dependency other than those declared in a dependency constraint are detected. The existence of package dependency cycles can also be automatically checked by a JUnit test.
Dependency Constraint Tests
The following example JUnit test case tests whether a package dependency constraint is met. This test fails if any package dependency other than those declared in the dependency constraint are detected:
import java.io.*; import java.util.*; import junit.framework.*; public class ConstraintTest extends TestCase { private JDepend jdepend; public ConstraintTest(String name) { super(name); } protected void setUp() throws IOException { jdepend = new JDepend(); jdepend.addDirectory("/path/to/project/util/classes"); jdepend.addDirectory("/path/to/project/ejb/classes"); jdepend.addDirectory("/path/to/project/web/classes"); } /** * Tests that the package dependency constraint * is met for the analyzed packages. */ public void testMatch() { DependencyConstraint constraint = new DependencyConstraint(); JavaPackage ejb = constraint.addPackage("com.xyz.ejb"); JavaPackage web = constraint.addPackage("com.xyz.web"); JavaPackage util = constraint.addPackage("com.xyz.util"); ejb.dependsUpon(util); web.dependsUpon(util); jdepend.analyze(); assertEquals("Dependency mismatch", true, jdepend.dependencyMatch(constraint)); } public static void main(String[] args) { junit.textui.TestRunner.run(ConstraintTest.class); } }
Dependency Cycle Tests
The following example JUnit test case tests for the existence of package dependency cycles:
import java.io.*; import java.util.*; import junit.framework.*; public class CycleTest extends TestCase { private JDepend jdepend; public CycleTest(String name) { super(name); } protected void setUp() throws IOException { jdepend = new JDepend(); jdepend.addDirectory("/path/to/project/ejb/classes"); jdepend.addDirectory("/path/to/project/web/classes"); jdepend.addDirectory("/path/to/project/thirdpartyjars"); } /** * Tests that a single package does not contain * any package dependency cycles. */ public void testOnePackage() { jdepend.analyze(); JavaPackage p = jdepend.getPackage("com.xyz.ejb"); assertEquals("Cycle exists: " + p.getName(), false, p.containsCycle()); } /** * Tests that a package dependency cycle does not * exist for any of the analyzed packages. */ public void testAllPackages() { Collection packages = jdepend.analyze(); assertEquals("Cycles exist", false, jdepend.containsCycles()); } public static void main(String[] args) { junit.textui.TestRunner.run(CycleTest.class); } }
Main Sequence Distance Tests
The following example JUnit test case tests the conformance of packages to a distance from the main sequence (D) within project-defined tolerances:
import java.io.*; import java.util.*; import junit.framework.*; public class DistanceTest extends TestCase { private JDepend jdepend; public DistanceTest(String name) { super(name); } protected void setUp() throws IOException { jdepend = new JDepend(); jdepend.addDirectory("/path/to/project/ejb/classes"); jdepend.addDirectory("/path/to/project/web/classes"); jdepend.addDirectory("/path/to/project/thirdpartyjars"); } /** * Tests the conformance of a single package to a * distance from the main sequence (D) within a * tolerance. */ public void testOnePackage() { double ideal = 0.0; double tolerance = 0.125; // project-dependent jdepend.analyze(); JavaPackage p = jdepend.getPackage("com.xyz.ejb"); assertEquals("Distance exceeded: " + p.getName(), ideal, p.distance(), tolerance); } /** * Tests the conformance of all analyzed packages to a * distance from the main sequence (D) within a tolerance. */ public void testAllPackages() { double ideal = 0.0; double tolerance = 0.5; // project-dependent Collection packages = jdepend.analyze(); Iterator iter = packages.iterator(); while (iter.hasNext()) { JavaPackage p = (JavaPackage)iter.next(); assertEquals("Distance exceeded: " + p.getName(), ideal, p.distance(), tolerance); } } public static void main(String[] args) { junit.textui.TestRunner.run(DistanceTest.class); } }
Writing JUnit tests to detect unwanted dependencies and package cycles can be awkward. Bob Martin contributed the Module Dependencies FitNesse fixture that allows you to represent your package dependencies as a table. The fixture uses the JDepend API to ensure that only the dependencies declared in the table actually exist in your software.
For example, the following table describes a system with three
components: ejb
,
web
, and util
. The ejb
and web
components depend upon the util
component.
| Module Dependencies | |||
| ejb | web | util | |
| ejb | X | ||
| web | X | ||
| util |
When this table is executed as a FitNesse fixture, and if the ejb
and web
components actually did depend upon
the util
component, then the cells containing an X would
be colored green. Any other unexpected component dependencies, such
as the ejb
component depending on the web
component, would result in the corresponding cell turning red.
Cycles result in all corresponding cells within the cycle to turn red and be marked with the word 'cycle'. The fixture sports other handy features, as well. Refer to Bob's blog for detailed usage information.
The Module Dependencies fixture is distributed with
JDepend in the contrib/fitnesse
directory.
Ant includes a task for automatically running JDepend.
Java class file directories to analyze are defined by the nested
<classespath>
element.
Text Reports
The following example Ant task runs JDepend on the build
directory and writes the text report to
the docs/jdepend-report.txt
file:
<target name="jdepend"> <jdepend outputfile="docs/jdepend-report.txt"> <exclude name="java.*"/> <exclude name="javax.*"/> <classespath> <pathelement location="build" /> </classespath> <classpath location="build" /> </jdepend> </target>
XML Reports
Ant 1.5 and above includes a format
attribute for the
JDepend Ant task and a default XSL stylesheet to transform a JDepend
XML report into an HTML report.
The following example Ant task runs JDepend on the build
directory, writes the XML report to
the docs/jdepend-report.xml
file, and generates
the jdepend.html
file using the jdepend.xsl
stylesheet distributed with Ant 1.5 (and above) in
the etc
directory:
<target name="jdepend"> <jdepend format="xml" outputfile="docs/jdepend-report.xml"> <exclude name="java.*"/> <exclude name="javax.*"/> <classespath> <pathelement location="classes" /> </classespath> <classpath location="classes" /> </jdepend> <style basedir="docs" destdir="docs" includes="jdepend-report.xml" style="${ant.home}/etc/jdepend.xsl" /> </target>
JDepend has the following known limitations:
Cyclic dependency detection may not report all cycles reachable from a given package. The detection algorithm stops once any given cycle is detected. If the same cycle is reachable from another package, the cycle may be reported more than once. In general, you want to aggressively remove any cycles.
JDepend does not collect source code complexity metrics. If you are interested in collecting these types of metrics, the JavaNCSS tool referenced in the Resources section is recommended.
The design quality metrics generated by JDepend are imperfect. They are intended to be used to pragmatically and responsibly measure design quality in a relative sense, rather than as a yard stick for all designs.
Java interfaces are treated as equals with Java abstract classes. In other words, although there are practical design advantages to using interfaces in concert with abstract classes, JDepend treats them uniformly in the calculation of abstractness. Likewise, abstract classes that implement interfaces are counted as abstract classes, in addition to their interface, regardless of whether they are always referenced outside the package as their interface type.
JDepend does not currently support the calculation of Ca and Ce in terms of the number of classes inside a package that have afferent or efferent couplings to classes inside other packages. Rather, JDepend calculates Ca and Ce strictly in terms of the number of packages with which a package has afferent or efferent couplings, based on the collective analysis of all imported packages. This deviates slightly from the original Ca and Ce definitions proposed by Robert Martin.

Many thanks to Robert Martin for originally describing these design quality metrics and writing the C++ dependency analyzer from which JDepend was adapted. I am especially grateful that he allowed me to stand on his shoulders in adapting his work for the Java community.

Maine man to be sentenced for infant’s death
BANGOR, Maine (AP) - A Maine man is due to be sentenced for the death of a 6-month-old-boy in Millinocket, Maine.
A judge found Jessee Mackin guilty of manslaughter in the baby’s death in May, 2015. Mackin was living with the baby’s mother in Millinocket at the time. The baby, Larry Earl Lord, died after being brought unresponsive to a hospital.
Mackin is being sentenced Friday in Superior Court in Bangor.
The baby was the son of Anthony Lord, who’s serving two life prison sentences for a shooting rampage that claimed two lives and injured four others in 2015. Lord said he was overcome with grief over his son’s death before the shootings.

For the ackee and mushrooms, heat the oil in a heavy-based pan over a medium heat. Add the sliced onion and peppers and fry for 4-5 minutes, or until softened, stirring regularly.
Add the chopped tomato and continue to fry for 1-2 minutes, stirring occasionally, or until the tomatoes have started to break down.
Add the mushrooms and continue to fry for 2-3 minutes, or until the liquid released by the mushrooms has evaporated.
Add boiling water, as necessary, to loosen the sauce mixture, stirring until well combined in the mixture. Season, to taste, with salt and freshly ground black pepper.
Add the ackee and carefully fold it into the sauce. Simmer for 2-3 minutes, or until heated through, then sprinkle over the spring onion. Remove from the heat and keep warm.
For the steak, rub one teaspoon of the oil all over the pieces of fillet steak. Heat a heavy-based pan over a medium heat until hot, then add the steak pieces and fry for 1-2 minutes on each side (for medium-rare), or until cooked to your liking. Remove from the heat and set aside.
Meanwhile, heat the remaining half a teaspoon of oil in a separate, heavy-based pan over a medium heat. Add the onion and sweet pepper and fry, stirring regularly, until softened.
Add the remaining steak ingredients and continue to fry for 4-5 minutes, stirring regularly, until the vegetables are just cooked through. Season, to taste, with salt and freshly ground black pepper. (NB: Bear in mind that the soy sauce is quite salty.)
Add the cooked steaks to the pan and cook until heated through.
To serve, place two pieces of fillet steak onto each of four serving plates. Pour over the pepper and tomato sauce. Spoon the ackee and mushrooms alongside.

Don't Expect Any New Ferrari Models Next Year
For once, Ferrari is slowing things down.
by Jared RosenholtzIn case you haven't been paying attention, Ferrari has released five all-new models in 2019. The two most recent reveals include the Roma Gran Tourer and the hybrid SF90 Stradale, each of which serves a very different purpose in the company's lineup. Ferrari says it plans to reveal 15 new models within a five-year window. So that leaves ten more vehicles including the upcoming Purosangue SUV.
But unlike 2019, 2020 will not be a landmark year for Ferrari reveals. Speaking to Autocar, Ferrari commercial chief Enrico Galliera said, "We've committed to introducing 15 new models in a five-year plan, and we launched five in 2019, so certainly something will happen in the future. But 2020 for us is a year of consolidation."
"We just introduced five new cars, some of them are in new segments; now we need to make sure that our network and clients can clearly understand the position of the new models. 2020 will not have the same launch rate, and we'll be more focused on creating the success of the models we've introduced in 2019," he added. This is not a clear indication that 2020 will be completely devoid of new Ferrari reveals but we certainly won't see as many as five.
With fewer reveals in 2020, it should give Ferrari customers (and dealerships) more time to become familiar with the new models and figure out how they slot it with the existing product. Roma, as an example, feels like it will slot in slightly above the Portofino but Ferrari has been very tight-lipped on exactly where the car will sit in the range.

As for future hybridization, we know Ferrari is working on new ways to incorporate battery technology, as we've seen recently on the SF90. When asked if Ferrari would introduce hybrid versions to existing models like the new Roma, Galliera said, "We could fit a hybrid powertrain to [the Roma] platform, there's no doubt about it. But we would never do it on the same model." Therefore, when we do start to see more hybrid vehicles from Ferrari, they will likely be all-new models not new versions of existing products.
