--- layout: post authors: ["Ben Waugh"] title: Workshop for High-Energy Physics at UCL date: 2012-11-14 time: "11:00:00" tags: ["University College London"] ---
Following the success of the open bootcamp at UCL in April/May this year, we decided to have a go at introducing some Software Carpentry to the first-year postgraduate students in my own research group, High-Energy Physics (HEP). There is already a longstanding University of London intercollegiate lecture programme for these students, including some programming in C++ and Python. The new workshops aim to help participants consolidate and extend their existing Python knowledge, as well as learning about more general best practice in software development, by following an extended worked example using version control and test-driven development.
In a variation on the "normal" two-day Software Carpentry format, we are running two one-day workshops about a term apart, with the first taking place last Thursday. Attendance was 65% (13 of 20 students) with a single instructor (me) and two other helpers: Sean Brisbane of the Oxford HEP group, where he intends to run something similar, and James Hetherington of UCL's new Research Software Development Team.
Students were able to use their own laptops, or use the provided UCL standard Windows desktop machines to SSH to Linux machines at CERN, UCL or their own institution. It took a while to get the Exceed X server configured appropriately on the Windows machines, and get everyone connected to a suitable Linux machine, which also meant creating accounts on the UCL HEP cluster for students with no other Linux system available.
We used PyROOT so that we could use the ROOT toolkit, which is ubiquitous in HEP, while still programming in Python rather than C++. Predictably there were various problems with incompatible versions of Python and ROOT, but these were all overcome. For version control we used Git, with an emphasis on its use as a personal extended undo facility: we didn't get as far as branching or setting up a shared repository. Nor did we get as far as I had hoped into unit testing, but we did some informal testing in the Python interpreter, and introduced the Python debugger.
Next we will arrange some online tutorials and discussion forums, and use the feedback from these to guide the plan for the second workshop in February.

Bianca Andreescu Wins Lou Marsh Trophy As Canada’s Athlete Of The Year
by Staff, The Canadian PressTennis star Bianca Andreescu has won the 2019 Lou Marsh Trophy as Canada’s athlete of the year.
Andreescu is the first tennis player to win the award. The native of Mississauga, Ont., became the first Canadian to win a Grand Slam singles title when she defeated American star Serena Williams in the final of the U.S. Open.
“Wow, I’m so thankful for this award. I was not expecting it and to be the first tennis player to win is even more surreal,” said Andreescu. “None of my success this year would have been possible without the support from all of Canada.”
The winner of the Toronto Star award is selected annually by a panel of sports journalists from across the country. Andreescu was a unanimous choice for this year’s award.
Her star-making performance at the U.S. Open capped a stellar year for the 19-year-old, who also won the Rogers Cup in Toronto and the prestigious BNP Paribas Open at Indian Wells, Calif.
She earned over US$6.5 million on the season and is ranked fifth in the world after starting the year ranked No. 152.
Other finalists included golfer Brooke Henderson, sprinter Andre De Grasse, Atlanta Braves pitcher Mike Soroka and St. Louis Blues goaltender Jordan Binnington.
“Canadian sports crushed it this year so there are definitely many other athletes who deserve a piece of this award as well – we all motivate each other to be better,” said Andreescu. “I can’t wait for what 2020 will bring and am always proud to represent Canada at the highest level.”
The Lou Marsh Trophy has been awarded annually since 1936 with a three-year hiatus during the Second World War.

array pg_convert ( resource $connection , string $table_name , array $assoc_array [, int $options = 0 ] )
pg_convert() checks and converts the values in assoc_array into suitable values for use in an SQL statement. Precondition for pg_convert() is the existence of a table table_name which has at least as many columns as assoc_array has elements. The fieldnames in table_name must match the indices in assoc_array and the corresponding datatypes must be compatible. Returns an array with the converted values on success, FALSE otherwise. Note: If there are boolean fields in table_name don't use the constant TRUE in assoc_array. It will be converted to the string 'TRUE' which is no valid entry for boolean fields in PostgreSQL. Use one of t, true, 1, y, yes instead. Warning: This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.
An array of converted values, or FALSE on error.


Users access notifications by clicking the bell icon in the shell bar at the top right of the screen. In the
notifications popover, the user can order notifications in various ways, take action, and navigate to the
source of a specific notification.
High-priority notifications are shown using the banner. The banner appears on the upper right-hand corner of
the screen for a short period of time and then disappears. It's recommended to set a notification to high
priority if you need to get the user’s immediate attention. In this case you need to use the
NotificationService and pass the content of the notifications as a template or a component.
fd-notification
component. The width
input property controls the width of the
notification. The width of the notification cannot exceed 40rem. The input property
mobile
specifies if the notification is in mobile mode.

When I first started work on brislink the only itch that I wanted to scratch was to create something.At that time it did not matter what I made so long I made something.It so happened that I was learning a new technology so I was really pumped up to work with it.
In its first iteration brislink was a url sharing application.All it did was to allow the users to share links to stories on the internet that they found interesting.I was really proud of my work but I soon found out that it was not really useful to me.In the first week of launch I was very aggressive in submitting links but I soon lost interest and just left it as it was.It was much later that I decided to make it into what it is today.
I blog frequently.Most of the time on my personal blog.After writing a couple of posts I used to submit the links on gamefaqs hoping that someone would read it and give me some valuable feedback.I did get a few encouraging nods but most of the time my writing faded into obscurity.It was during one day when I was submitting my article that I thought to myself
“What if instead of submitting my articles manually to others I could broadcast it automatically where any one could see it?”
Based on this simple initial idea ,which was born out of my problem of having to submit my posts to others for them to read, I reimagined brislink.Soon I started blogging both on my own blog and on brislink.This gave rise to another problem that I was sure would be shared by many of you as well.
Often we tend to blog on mutiple websites.It was true for me and some other folks that I knew.It would be nice if someone could track these posts of the user across these multiple websites and collate them in one place.I decided to implement it.After a few days of hacking I managed to make it work.Here is my profile it contains all the contrbutions that I have made to various websites.It is really statisfying to see all your work nicely arranged right before your eyes.
At the time of my wirting not many people use brislink.To be completely honest I am the only one who is using it.But it makes me really happy.I had a few problems that I managed to solve and if it helps someone else in the process or makes them happy it is all bonus to me.
brislink has reincarnated as specter, the posts in the brislink blog have moved to my personal blog

Utopian V2 Frontend Sneak Peeks
We are working hard to bring back a better, scalable and secure version of our frontend. Thanks to an amazing collaboration with @hernandev, we are building the foundation for the new frontend.
The new frontend will store no tokens from SteemConnect and on top of that, client tokens will always be encrypted for maximum security. It is built with Vue.js and the Quasar Framework.

Utopian Signup Module Improvements
Before we began using the signup module to onboard new Utopians, we worked hard at debugging and improving it. This week, we fixed multiple bugs and added a few important features.
A completely new system to avoid abuse
To save the dedicated Steem Power we have from abuse as we create new accounts, a new flow has been implemented.
If you are a great contributor with a well-established GitHub account, the registration will be instantaneous. The signup will only require email verification, following which your account will be created.
If your Github account isn’t immediately verifiable, you will have two options:
- Insert an invitation code. Invitation codes can be requested via our Discord server.
- Proceed by email and sms verification. A manual verification will be done in this case and an account will only be created after approval.
We are confident these changes will make the signup much less likely to be abused.
The new signup system is now working on the mainnet and creating accounts for awesome Open Source contributors!
Invisible Recaptcha
An invisible recaptcha has been implemented to mitigate potential bots and improve the security mechanisms of the signup. We are also working on implementing IP, email, and virtual number filters. Such security measures are essential to avoid any potential abuse of our Steem Power and to ensure that we use it only to create genuine accounts.
Un-delegation Bot
Steem accounts created through our new signup system receive Steem Power delegation from Utopian.io to begin contributing and participating in the community. To encourage users to be active on the platform and on the blockchain, and to ensure no Steem Power is wasted on unused accounts, we will automatically retract the delegation 45 days post account creation. This bot (coded in Python) is made available thanks to the efforts of @amosbastian.
Bug Fixes
The improved signup module instantly checks if the username already exists on the Steem blockchain, and throws a more understandable error to highlight this fact. Other minor issues relating to checking username format have been resolved.
Utopian.tasks Resteem Bot
In an effort to showcase task requests submitted to Utopian.io and scored by our team, @amosbastian wrote a bot to resteem all valid task requests to @utopian.tasks. Outstanding task requests will also be resteemed by the main @utopian-io account for maximum exposure.
Branding of our Team’s Tools
To give tip.utopian.io and review.utopian.io a more user friendly and Utopian-themed look and feel, @ms10398 reworked the page design and added our official graphic branding elements.
Landing Page Improvements
In order to make our curation efforts more accessible and easier to understand, we have updated our landing page at join.utopian.io.
New Login Modal
A new login modal now pops up when clicking on Login on the landing page, to give newcomers useful options for the different frontends they can use to contribute to Utopian.io.
Contribution Guidelines
This week we have finally switched from Rules to Guidelines. You can forget the word “rules” which has been so critical in Utopian so far.
You can now contribute freely, as long as you provide quality work. You can follow our guidelines found on join.utopian.io/guidelines to learn about the best practices to follow in your posts for improving your chances of receiving a high score and getting rewarded.
The same new Guidelines Landing Page has also received significant updates, making it much more readable and accessible, as seen in the screenshot below.
Stay tuned for more!
We are creating a lot of educational material to help teach the community how to contribute and provide the quality work we expect on the platform. Follow the new account @utopian.edu to be the first to access all of our free educational content, covering all categories.
The very first video tutorial in the series is planned for release TOMORROW! Don’t miss it!
Content Plan
Thanks to the amazing work of our PR department, which includes @techslut and @imwatsi, we were able to come up with a lot of new interesting content, as well as a final content schedule.
We have kickstarted:
The Utopian Weekly, with updates on our progress
The first People Of Utopian , with interviews of active and influential members of Utopian
The Top of Utopian, with highlights of staff picks and statistics on contributions
The Utopian Mag. A new magazine about everything Open Source. The first edition will be published next week!

The paths category defines other directories to add into a standard path as well as additional INI files and the location of the shared token database. Adding directories to standard paths is useful both in network situations and if you want your application installed in a special directory but linked to the WORLD directory. This category uses five different keys, as shown below.
<standard path> = <additional paths>
Each standard path is its own key, and you can merge other directories into any standard path. Some examples are shown below.
top = C:\GEOWORKS C:\PCGEOS world = E:\INSTALL\NEWAPP userdata font = N:\NETFONTS F:\SPECFONT
ini = <file names>
This key defines up to three additional INI files to be loaded read-only. When GEOS searches for a key, the local (current) INI file is scanned first, followed by the additional INI files in the order they're defined. The first occasion of the key will be used; thus, the local INI file can supersede other settings.
ini = personal.ini INI\mydevice.ini n:\shared.ini
inisaved = <files>
This key is used only if GEOS is run with the /psaved argument. That is, if the user runs GEOS thus:
C>GEOS /psaved
then GEOS will look for the inisaved key rather than the ini key for additional INI files. Similarly, if the user instead runs
C>GEOS /pxxx
GEOS will look for a key called inixxx for the names of the files to be used.
inisaved = net.ini inisaved = demo.ini net.ini
sharedTokenDatabase = <path>
This key defines the location of the shared token database file. This key is most useful in network situations, when many users may be sharing a single token database.
sharedTokenDatabase = N:\NETFILES\TOKEN_DA.000


This is just a small project to visualize follower relationships on Micro.blog. I started it when I realized that I wanted to discover more users and wanted a concise way to start seeing some of the relationships between users. I didn't want anything fancy, but at least something that let me quickly scan user followers and their follower networks. Since Micro.blog has a public API, I figured I'd throw something together.
I could probably get away with using my own token, but I figure I'd rather not expose it and risk any trouble. You'll need to get your own. Fortunately, if you have a Micro.blog account, you can generate one very easily on the accounts page. Think up a witty name and click that "Generate Token" button to get your own. Then just copy the value and paste it into the "token" field below. From there, consider which user you'd like to start with and put his or her username into the "user" field. Then click "start" and you'll see a list of all followers. That list includes the user, which is kind of weird, but there's no data cleanup at the moment. From there, just click on another user's information and the followers for that user will appear in the next column.
You'll also need to disable CORS in your browser. CORS is a technology to avoid cross-site scripting attacks by limiting whether requests are allowed by their origin. This is usually by-passed by querying a trusted service, but this is a web page with no backing server. You'll need to just configure the browser to ignore this security restriction. Instructions for Chrome, Firefox, and Safari are available online (note that you may need some additional setup on Chrome than what's documented in the previously linked article).
Try "Grayson" or "manton"

Interface: CC2420Config
interface CC2420Config
An HAL abstraction of the ChipCon CC2420 radio. This abstraction
deals specifically with radio configurations. All get() and set()
commands are single-phase. After setting some values, a call to
sync() is required for the changes to propagate to the cc2420
hardware chip. This interface allows setting multiple parameters
before calling sync().

Verily, Ibrahim (Abraham) was an Ummah (a leader having all the good righteous qualities), or a nation, obedient to Allah, Hanifa (i.e. to worship none but Allah), and he was not one of those who were Al-Mushrikun (polytheists, idolaters, disbelievers in the Oneness of Allah, and those who joined partners with Allah). |

Quick overview
Menus and navigation are some of the most important elements for any website or web app and their design and ease-of-use are key factors that can determine a page's bounce rates. The navigation module takes a step back from the complicated menu and navigation design paradigms of the modern web, using HTML5 elements (i.e. header
, nav
and footer
) for basic navigation, while providing fully accessibility for screen readers. Apart from the simple horizontal navigation (headers) and vertical menus (sidebars), we opted to add a responsive slide-in drawer menu that works well with any page layout. Finally, footers are also part of the navigation module, as they can often provide the user with useful information and/or links that are very important to enhancing their experience.
Quick start
To use the navigation module, simply include the link to the flavor you are using and start writing your HTML page as usual. One suggestion we will make is to add the following line inside your HTML page's
to utilize the viewport meta tag:
<meta name="viewport" content="width=device-width, initial-scale=1">
Header
The
HTML element is used for a page's top horizontal navigation menu. It can contain a unique .logo
element as its first child (this structure is not mandatory, but still recommended as a best practice), which can be either text (with or without a link) or an image. The rest of the elements inside the
must be button elements (i.e. <button>
, <input type="button">
, role="button"
or .button
) in order to be styled properly. Textual separators between those can be added using
elements.
Sample code
 Logo <button>Home</button> News | <button>About</button> Contact
Notes
- The

element is partially responsive on smaller screen devices. More specifically, when the content inside it exceeds the width of the viewport (ie. overflows to the right), users will be able to scroll horizontally in order to see the rest of the menu. - The

element does not display asfixed
by default. You can, however, alter this CSS property manually, if you so desire.
 Logo <button>Action 1</button> Action 2 Action 3
Do: You can mix different elements styled like buttons inside a
element. In fact, we strongly recommend doing so, if you need to.

Logo

Logo
Link

Don't: The .logo
element should not be a <button>
element, have the .button
class or the role="button"
attribute. On the other hand, links and labels in the
should not be without a .button
class or a role="button"
attribute. Ignoring this rule might cause unexpected behavior.
Drawer
The drawer component is used to create responsive and collapsible navigation menus. To create the drawer system, follow the steps presented below:
- Inside your

element, add a
element with the.drawer-toggle
class (remember to add the.button
class to apply the necessary styles). - Create an
<input type="checkbox">
element. Give it anid
to be able to link it to the necessary interactive elements. - Immediately after the previous
<input type="checkbox">
, create a

element with the.drawer
class. This is where you will put your menu's contents. - Add an empty

element inside your.drawer
, adding the.close
class to it. - Finally, link the
.drawer-toggle
and.close
elements to theid
of your<input type="checkbox">
.
Drawers are responsive and will expand into normal containers on larger screens. If you want to avoid this, add the .persistent
class to both your .drawer-toggle
and .drawer
elements. You can also change the position of the drawer from the left side of the screen to the right by applying the .right
class to your .drawer
element.
Sample code
   <input type="checkbox" id="drawer-checkbox">
  Home

Notes
- The
.drawer
component can be easily and effectively combined with the grid module's system and classes, as well as the utility module's responsive visibility helper classes to create fully responsive navigation menus. - It's best to use the
.drawer
component in combination with a
element that has the.sticky
class (check the last section of this page).
  Home
Do: You can apply the .drawer
class to a
element, effectively making your page's navigation menu collapse on smaller screen sizes.
<input type="checkbox" id="drawer-checkbox">

Bad drawer

Don't: The syntax and structure of the drawer container is very strict. Try to follow it exactly as described in this section.

 <input type="checkbox" id="drawer-checkbox">
  Home

Page content

Do: You can combine the .drawer
component with the grid system, similarly to any other element or component. The .drawer
will be displayed as a slide-in menu on smaller screens, but it's part of the layout on medium-sized and larger screens.
   <input type="checkbox" id="drawer-checkbox">
...
     <input type="checkbox" id="drawer-checkbox">
...

Don't: Remember to apply the .persistent
class to the .drawer-toggle
and .drawer
elements to avoid unexpected behavior.
Sticky headers and footers
You can create sticky headers and footers, using the .sticky
class on either of these elements.
Sample code
 Logo <button>Home</button> <button>About</button>

Notes
- Sticky headers and footers are compatible with modern browsers, but might not display properly in older browsers. Support is being added over time, so be sure to check out if your target platforms support
position:sticky
.

Creating Documentation¶
This is Michael Lamoureux’s documentation on some of the tricky points in using Jupyter notebooks.
It also documents how to create and post documentation useing Read The Docs, as this is also a bit tricky.
Read this at https://docs123455.readthedocs.io. Eventually I will host it under a reasonable name.
Using Read The Docs¶
I’m using a system called Read The Docs. You can read about it here: readthedocs.org
The idea is simple:
create a bunch of files
push it to your github repo
let the Read The Docs system publish it on the web for you.
There is a bit more to it than that. You should first create the documentation set on your own computer, using the Sphinx software. To install Sphinx, you need to run pip from within a terminal window:
pip install Sphinx
If you plan to use MarkDown as your language, you should also install this extension
pip install recommonmark
Also, you will have to add the following line to your conf.pu file (once it is created), like this:
pip install recommonmark
Otherwise, you will be using reStrucutre Text files for the documentation.
For the advantages of reStrucutured Text (.rst) files over Markdown (.md) files, check out the blog by www.ericholscher.com/blog
For me (MLamoureux), I plan to use Markdown, since that is what I am familiar with.
Using Sphinx¶
Don’t forget to do a pip install, to get the software. You only need to do this once on your system
pip install sphinx
(On a Mac, you might need to do install Python3 and use pip3. YOu may also need to install XCode developer tools. See next section.)
Now, create a new directory (folder) somewhere on your hard drive. From the terminal, cd into that directory, then run quickstart to set things up with Sphinx.
cd thatDirectory
sphinx-quickstart
This will create several files in the current directory. In ths new “source” directory is a file called index.rst, which you will list the files you want compiled into the documentation. You don’t need to list the file extension. You do have to get the spacing right.
The files you creae, like ChapterOne.md, ChapterTwo.md etc. can be written in Markdown. Use whatever editor you like. Once they are written, and the file name put into index.rst, you can make the webpage.
CD (change directory) back into thatDirectory, and run
make html
This will then create a webpage for the book that you can open with
open build/html/index.html
Or use your browser to open it directly.
Using Github¶
You can push this all to github, for public storage.
Create a public repo on your github account, clone it onto your computer, then copu you Docs folder into this new, cloned directly.
To enable automatic builds, in your github account go to “Settings”, look for “Webhooks” and pick the one for ReadTheDocs.
Hosting your docs in public - ReadThe Docs¶
Set up an account on ReadTheDocs.org
Then Import a New Project, using their menu items. It will ask you to find your Github account, which you should do. Then select the repo that holds the documentation you want to use.
Then build it. Look out for errors.
Errors¶
One error I got was that the build failed, because it could not find a file contents.rst. The solution is to edit the config file conf.py, and add the line
master_doc = 'index'


In the JMockit toolkit, the Faking API provides support for the creation of fake implementations. Typically, a fake targets a few methods and/or constructors in the class to be faked, while leaving most other methods and constructors unmodified.
Fake implementations can be particularly useful in tests which depend on external components or resources such as e-mail or web services servers, complex libraries, etc. Often, the fakes will be applied from reusable testing infrastructure components, not directly from a test class.
The replacement of real implementations with fake ones is completely transparent to the code which uses those dependencies, and can be switched on and off for the scope of a single test, all tests in a single test class, or for the entire test run.
In the context of the Faking API, a fake method is any method in a fake class that gets annotated with
@Mock
.
A fake class is any class extending the mockit.MockUp<T>
generic base class, where T
is the type
to be faked.
The example below shows several fake methods defined in a fake class for our example "real" class,
javax.security.auth.login.LoginContext.
public final class FakeLoginContext extends MockUp<LoginContext> {
@Mock
public void $init(String name, CallbackHandler callback) {
assertEquals("test", name);
assertNotNull(callback);
}
@Mock
public void login() {}
@Mock
public Subject getSubject() { return null; }
}
When a fake class is applied to a real class, the latter gets the implementation of those methods and constructors which have corresponding fake methods temporarily replaced with the implementations of the matching fake methods, as defined in the fake class. In other words, the real class becomes "faked" for the duration of the test which applied the fake class. Its methods will respond accordingly whenever they receive invocations during test execution. At runtime, what really happens is that the execution of a faked method/constructor is intercepted and redirected to the corresponding fake method, which then executes and returns (unless an exception/error is thrown) to the original caller, without this one noticing that a different method was actually executed. Normally, the "caller" class is one being tested, while the faked class is a dependency.
Each @Mock
method must have a corresponding "real method/constructor" with the same signature in
the targeted real class.
For a method, the signature consists of the method name and parameters; for a constructor, it's just the parameters,
with the fake method having the special name "$init
".
Finally, notice there is no need to have fake methods for all methods and constructors in a real class. Any such method or constructor for which no corresponding fake method exists in the fake class will simply stay "as is", that is, it won't be faked.
A given fake class must be applied to a corresponding real class to have any effect.
This is usually done for a whole test class or test suite, but can also be done for an individual test.
Fakes can be applied from anywhere inside a test class: a @BeforeClass
method, a
@BeforeMethod
/ @Before
/ @BeforeEach
method (TestNG / JUnit 4 / JUnit 5), or from a @Test
method.
Once a fake class is applied, all executions of the faked methods and constructors of the real class get automatically redirected to the
corresponding fake methods.
To apply the FakeLoginContext
fake class above, we simply instantiate it:
@Test
public void applyingAFakeClass() throws Exception {
new FakeLoginContext());
// Inside an application class which creates a suitable CallbackHandler:
new LoginContext("test", callbackHandler).login();
...
}
Since the fake class is applied inside a test method, the faking of LoginContext
by
FakeLoginContext
will be in effect only for that particular test.
When the constructor invocation that instantiates LoginContext
executes, the corresponding "$init
"
fake method in FakeLoginContext
will be executed.
Similarly, when the LoginContext#login
method is called, the corresponding fake method will be executed, which in this case
will do nothing since the method has no parameters and void
return type.
The fake class instance on which these invocations occur is the one created in the first part of the test.
So far, we have only faked public instance methods with public instance fake methods.
Several other kinds of methods in a real class can also be faked: methods with protected
or "package-private" accessibility,
static
methods, final
methods, and native
methods.
Even more, a static
method in the real class can be faked by an instance fake method, and vice-versa (an instance
real method with a static
fake).
Methods to be faked need to have an implementation, though not necessarily in bytecode (in the case of native
methods).
Therefore, an abstract
method cannot be faked directly.
Note that fake methods don't need to be public
.
To demonstrate this feature, lets consider the following code under test.
public interface Service { int doSomething(); }
final class ServiceImpl implements Service { public int doSomething() { return 1; } }
public final class TestedUnit {
private final Service service1 = new ServiceImpl();
private final Service service2 = new Service() { public int doSomething() { return 2; } };
public int businessOperation() {
return service1.doSomething() + service2.doSomething();
}
}
The method we want to test, businessOperation()
, uses classes that implement a separate interface,
Service
.
One of these implementations is defined through an anonymous inner class, which is completely inaccessible (except for the use of
Reflection) from client code.
Given a base type (be it an interface
, an abstract
class, or any sort of base class), we can write a test which
only knows about the base type but where all implementing/extending implementation classes get faked.
To do so, we create a fake whose target type refers only to the known base type, and does so through a type variable.
Not only will implementation classes already loaded by the JVM get faked, but also any additional classes that happen to get loaded by
the JVM during later test execution.
This ability is demonstrated below.
@Test
public <T extends Service> void fakingImplementationClassesFromAGivenBaseType() {
new MockUp<T>() {
@Mock int doSomething() { return 7; }
};
int result = new TestedUnit().businessOperation();
assertEquals(14, result);
}
In the test above, all invocations to methods implementing Service#doSomething()
will be redirected to the fake method
implementation, regardless of the actual class implementing the interface method.
When a class performs some work in one or more static initialization blocks, we may need to stub it out so it doesn't interfere with test execution. We can define a special fake method for that, as shown below.
@Test
public void fakingStaticInitializers() {
new MockUp<ClassWithStaticInitializers>() {
@Mock
void $clinit() {
// Do nothing here (usually).
}
};
ClassWithStaticInitializers.doSomething();
}
Special care must be taken when the static initialization code of a class is faked.
Note that this includes not only any "static
" blocks in the class, but also any assignments to static
fields
(excluding those resolved at compile time, which do not produce executable bytecode).
Since the JVM only attempts to initialize a class once, restoring the static initialization code of a faked class will have no
effect.
So, if you fake away the static initialization of a class that hasn't been initialized by the JVM yet, the original class initialization
code will never be executed in the test run.
This will cause any static fields that are assigned with expressions computed at runtime to instead remain initialized with the
default values for their types.
A fake method can optionally declare an extra parameter of type mockit.Invocation
, provided it is the
first parameter.
For each actual invocation to the corresponding faked method/constructor, an Invocation
object will be
automatically passed in when the fake method is executed.
This invocation context object provides several getters which can be used inside the fake method.
One is the getInvokedInstance()
method, which returns the faked instance on which the invocation occurred
(null
if the faked method is static
).
Other getters provide the number of invocations (including the current one) to the faked method/constructor, the invocation arguments
(if any), and the invoked member (a java.lang.reflect.Method
or
java.lang.reflect.Constructor
object, as appropriate).
Below we have an example test.
@Test
public void accessingTheFakedInstanceInFakeMethods() throws Exception {
new MockUp<LoginContext>() {
Subject testSubject;
@Mock
void $init(Invocation invocation, String name, Subject subject) {
assertNotNull(name);
assertNotNull(subject);
// Verifies this is the first invocation.
assertEquals(1, invocation.getInvocationCount());
}
@Mock
void login(Invocation invocation) {
// Gets the invoked instance.
LoginContext loginContext = invocation.getInvokedInstance();
assertNull(loginContext.getSubject()); // null until subject is authenticated
testSubject = new Subject();
}
@Mock
void logout() { testSubject = null; }
@Mock
Subject getSubject() { return testSubject; }
};
LoginContext theFakedInstance = new LoginContext("test", new Subject());
theFakedInstance.login();
assertSame(testSubject, theFakedInstance.getSubject();
theFakedInstance.logout();
assertNull(theFakedInstance.getSubject();
}
Once a @Mock
method is executing, any additional calls to the corresponding faked method are also
redirected to the fake method, causing its implementation to be re-entered.
If, however, we want to execute the real implementation of the faked method, we can call the proceed()
method on the
Invocation
object received as the first parameter to the fake method.
The example test below exercises a LoginContext
object created normally (without any faking in effect at
creation time), using an unspecified configuration
.
@Test
public void proceedIntoRealImplementationsOfFakedMethods() throws Exception {
// Create objects used by the code under test:
LoginContext loginContext = new LoginContext("test", null, null, configuration);
// Apply fakes:
ProceedingFakeLoginContext fakeInstance = new ProceedingFakeLoginContext();
// Exercise the code under test:
assertNull(loginContext.getSubject());
loginContext.login();
assertNotNull(loginContext.getSubject());
assertTrue(fakeInstance.loggedIn);
fakeInstance.ignoreLogout = true;
loginContext.logout(); // first entry: do nothing
assertTrue(fakeInstance.loggedIn);
fakeInstance.ignoreLogout = false;
loginContext.logout(); // second entry: execute real implementation
assertFalse(fakeInstance.loggedIn);
}
static final class ProceedingFakeLoginContext extends MockUp<LoginContext> {
boolean ignoreLogout;
boolean loggedIn;
@Mock
void login(Invocation inv) throws LoginException {
try {
inv.proceed(); // executes the real code of the faked method
loggedIn = true;
}
finally {
// This is here just to show that arbitrary actions can be taken inside the
// fake, before and/or after the real method gets executed.
LoginContext lc = inv.getInvokedInstance();
System.out.println("Login attempted for " + lc.getSubject());
}
}
@Mock
void logout(Invocation inv) throws LoginException {
// We can choose to proceed into the real implementation or not.
if (!ignoreLogout) {
inv.proceed();
loggedIn = false;
}
}
}
In the example above, all the code inside the tested LoginContext
class will get executed, even though
some methods (login
and logout
) are faked.
This example is contrived; in practice, the ability to proceed into real implementations would not normally be useful for
testing per se, not directly at least.
You may have noticed that use of Invocation#proceed(...)
in a fake method effectively behaves like advice (from AOP
jargon) for the corresponding real method.
This is a powerful ability that can be useful for certain things (think of an interceptor or decorator).
Often, a fake class needs to be used throughout multiple tests, or even applied for the test run as a whole.
One option is to use test setup methods that run before each test method; with JUnit, we use the
@Before
annotation; with TestNG, it's @BeforeMethod
.
Another is to apply fakes inside of a test class setup method: @BeforeClass
.
Either way, the fake class is applied by simply instantiating it inside the setup method.
Once applied, a fake will remain in effect for the execution of all tests in the test class.
The scope of a fake applied in a "before" method includes the code in any "after" methods the test class may have (annotated with
@After
for JUnit or @AfterMethod
for TestNG).
The same goes for any fakes applied in a @BeforeClass
method: they will still be in effect during the
execution of any AfterClass
methods.
Once the last "after" or "after class" method finish being executed, though, all fakes get automatically "torn down".
For example, if we wanted to fake the LoginContext
class with a fake class for a bunch of related tests, we
would have the following methods in a JUnit test class:
public class MyTestClass {
@BeforeClass
public static void applySharedFakes() {
new MockUp<LoginContext>() {
// shared @Mock's here...
};
}
// test methods that will share the fakes applied above...
}
It is also possible to extend from a base test class, which may optionally define "before" methods that apply one or more fakes.
Sometimes, we may need to apply a fake for the entire scope of a test suite (all of its test classes), ie, a "global" fake. This can be done through external configuration, by setting a system property.
The fakes
system property supports a comma-separated list of fully qualified fake class names.
If specified at JVM startup time, any such class (which must extend MockUp<T>
) will be automatically applied
for the whole test run.
The fake methods defined in startup fake classes will remain in effect until the end of the test run, for all test classes.
Each fake class will be instantiated through its no-args constructor, unless an additional value was provided after the class name (for
example, as in "-Dfakes=my.fakes.MyFake=anArbitraryStringWithoutCommas
"), in which case the fake class should have a
constructor with one parameter of type String
.
There is one more special @Mock
method that can appear in a fake class: the "$advice
"
method.
If defined, this fake method will handle executions of each and every method in the target class (or classes, when applying the fake over
unspecified classes from a base type).
Differently from regular fake methods, this one needs to have a particular signature and return type:
Object $advice(Invocation)
.
For demonstration, lets say we want to measure the execution times of all methods in a given class during test execution, while still executing the original code of each method.
public final class MethodTiming extends MockUp<Object> {
private final Map<Method, Long> methodTimes = new HashMap<>();
public MethodTiming(Class<?> targetClass) { super(targetClass); }
MethodTiming(String className) throws ClassNotFoundException { super(Class.forName(className)); }
@Mock
public Object $advice(Invocation invocation) {
long timeBefore = System.nanoTime();
try {
return invocation.proceed();
}
finally {
long timeAfter = System.nanoTime();
long dt = timeAfter - timeBefore;
Method executedMethod = invocation.getInvokedMember();
Long dtUntilLastExecution = methodTimes.get(executedMethod);
Long dtUntilNow = dtUntilLastExecution == null ? dt : dtUntilLastExecution + dt;
methodTimes.put(executedMethod, dtUntilNow);
}
}
@Override
protected void onTearDown() {
System.out.println("\nTotal timings for methods in " + targetType + " (ms)");
for (Entry<Method, Long> methodAndTime : methodTimes.entrySet()) {
Method method = methodAndTime.getKey();
long dtNanos = methodAndTime.getValue();
long dtMillis = dtNanos / 1000000L;
System.out.println("\t" + method + " = " + dtMillis);
}
}
}
The fake class above can be applied inside a test, in a "before" method, in a "before class" method, or even for the entire test run by
setting "-Dfakes=testUtils.MethodTiming=my.application.AppClass
".
It will add up the execution times for all executions of all methods in a given class.
As shown in the implementation of the $advice
method, it can obtain the java.lang.reflect.Method
that is being
executed.
If desired, the current invocation count and/or the invocation arguments could be obtained through similar calls to the
Invocation
object.
When the fake is (automatically) torn down, the onTearDown()
method gets executed, dumping measured timings to standard
output.

I have always had a love for programming since I wrote my first chunky HTML webpage at 15. Since then I’ve been hooked; spending my spare time making fun (at least to me) little programs to expand my knowledge on different aspects of programming. In addition to my school-required, backend/algorithm heavy programs with C++, I’ve spent time delving into RESTful API’s and JSON; making programs connecting to the ISS, translation APIs, stock and crypto data, and even writing my own program to write and access my own JSON data. Since then I’ve been fascinated with the idea of putting a face to all the code I’ve been writing behind the scenes.
I make both web and backend based content.

Motorola's iconic Razr returns as an Android foldable with underwhelming specs
Flipping heck
by Carly PagePARTY LIKE IT'S 2004! Motorola has revived the iconic Razr flip-phone as a foldable Android handset.
The throwback device, which looks a lot like its 15-year-old Razr V3 predecessor, is being lauded as is "the first-ever clamshell-style flexible display". There's a 2.7in 600x800 'Quick View' screen on the outside for glancing at notifications and for, er, taking selfies, and the device opens to reveal a 6.2in 2142x 87621:9 OLED screen that and folds horizontally down the centre.
Motorola is making a big song and dance about the Razr's hinge. In a bid to dodge the borkage suffered by Samsung's foldable Galaxy Fold, the company has developed a "zero-gap" hinge that allows the Razr to close with both sides completely flat in a bid to protect the main display. This is good news as, much like the original Razr, you can dramatically slam the handset shut to end a phone call.
Under the hood, things get a bit, er, underwhelming. The Moto Razr packs a middle-of-the-road Qualcomm Snapdragon 710 chip, which comes paired with 6GB RAM, 128GB storage and a lowly 2,510mAh battery.
What's more, despite the fact it's launching in January, the Razr will ship with Android 9.0 Pie; Google's newer Android 10 launched in September, complete with added support for foldable form factors.
Elsewhere, the Moto Razr reboot sports a 16MP f/1.7 main camera, a 5MP front camera, USB-C 18W fast charging and NFC support. There's no 5G support baked in nor is the handset waterproof, though Motorola claims its nano-coating will protect against "sweat, spills and splashes."
The Motorola Razr will fetch $1,4999 when it launches in the US on Verizon's network, with pre-orders pegged to begin on 26 December - bad news for dads who had already added the handset to their Christmas lists. Here in Blighty, the Moto Razr will be available on the EE network. µ

Alon Zakai / June 2018
Emscripten runs the LLVM and Binaryen optimizers, e.g., emcc -O3 does
| LLVM IR | → | LLVM -O3 | → | wasm | → | Binaryen -O3 | → | final wasm |
The Binaryen optimizer has been tuned mostly for this LLVM case, and shrinks the final wasm by 15%
But non-LLVM compilers to wasm are important too! Go, AssemblyScript, etc.
Wasm GC will let some compile-to-js languages become compile-to-wasm languages:
| the same source code |
---→ ---→ |
JavaScript WebAssembly |
Possibilities here are mostly non-LLVM: TypeScript, Elm, Reason, etc. — expect to see a lot of activity here!
To accelerate that, Binaryen helps write compilers to wasm:
We want to optimize all compilers' output well, but lots of potential variety:
(call $report (loop $loop (result i32) ;; loop nested in call, odd... (br_if $loop (call $do-work) ) (call $get-result) ;; value flows out through the loop ) ) |
LLVM wouldn't emit that, but another compiler might!
To help here Binaryen has a "flatten" pass:
(call $report (loop $loop (result i32) (br_if $loop (call $do-work) ) (call $get-result) ) ) |
flatten ---→ |
(loop $loop (set_local $0 (call $do-work) ) (br_if $loop (get_local $0) ) (set_local $1 (call $get-result) ) ) (call $report (get_local $1) ) |
Flat IR is simpler, for example, no nested side effects:
(call $report (loop $loop (result i32) (br_if $loop (call $do-work) ) (call $get-result) ) ) |
flatten ---→ |
(loop $loop (set_local $0 (call $do-work) ) (br_if $loop (get_local $0) ) (set_local $1 (call $get-result) ) ) (call $report (get_local $1) ) |
Binaryen Optimizer Design
That boost takes Binaryen up to 4:
| -O4 | = | flatten + flat-only passes + -O3 |
Fully optimizes a bunch of testcases we noticed in AssemblyScript
Not much large non-LLVM code yet to test on, but on fuzz testcases -O4 shrinks an extra 20%
But also 3x slower compilation — shows importance of option to run without flattening!
Binaryen now goes up to 4
Maybe someday we'll go up to 11
That's it, thank you!

Welcome back! If you’re joining from the 1st post, you can skip ahead and start reading from the Chapter 2 title. If not, here’s a link to the first post as there’s some information in the beginning about this blog series.
Chapter 2: One Dimensional MC Integration
Monte Carlo is widely used to solve integrals of higher dimensions, where an analytical method is not possible, or other integral computational methods are intractable. Dr. Shirley selects a simple integral to show how effective Monte Carlo integration is.
Start reading the chapter right until you get to the code that computes the integral. Don’t worry if you don’t get it, I’m going to explain everything.
The integral is \(\int_0^2 x^2 dx\) which will compute the area under the curve, with the limits 0 to 2. So how do we translate this into a Monte Carlo estimate? I was a bit confused by the sudden appearance of the 2 being multiplied with the average(x^2, 0, 2) function. Why are we multiplying the sample average by 2? Well as it turns out, this how we perform Monte Carlo integration. A generic integral of the form:
\[F = \int_a^b f(x)\]
can be estimated with a Monte Carlo estimator by performing
\[(b-a) \frac{1}{N} \sum_{i=0}^{N-1} f(X_i)\]
\(x_i\) are uniformly distributed random numbers between 0 and 1, and \(N\) is the number of samples you pick.
Read the book right up until he proposes making his own PDF.
So the area function Dr. Shirley is trying to calculate is:
\[\int_0^2 C' r dr = \frac{1}{2} [C'r^2]_0^2 = 2C'
\\
1 = 2C'
\\
C' = \frac{1}{2}\]
Knowing that \(p(r) = C'r\) this leads to \(p(r) = \frac{r}{2}\). The rest is pretty readable and understandable so I’ll move onto something else.
A short introduction into probability theory with a bit more formality will go a long way into helping you understand what Dr. Shirley computes in the book and other future graphics problems.
We’ve been talking about random variables for a while. We know that generating a uniform random variable means that we use a function to generate a number in a particular range and since we stipulated that it is uniform, this also means that any other number in that range could have been picked with the exact same probability.
We’ll introduce some terms.
- \(X\) represents the random variable. Since we’re using random variables to estimate something, this also is referred to as a random variable!
- \(P(X)\) represents the probability of \(X\).
- \(P(X = x)\) represents the probability that \(X\) is a particular value \(x\).
To exemplify these terms, in our statistical experiment we are going to toss a coin twice.
- \(X\) is the number of heads that we get. This is the random variable that is the result of our 2 coin tosses. \(X\) will either be 0 (\(TT\)), 1(\(HT\) or \(TH\)) or 2(\(HH\)).
- \(P(X)\) will be the probability of getting 0, 1 or 2 heads.
- \(P(X = x)\) will be a particular sequence of coin tosses, such as \(TT\) or \(TH\).
The cumulative distribution function (CDF) and the probability mass/density function (pmf/PDF) are the 2 pillars of understanding the nature of a random variable. The reason I used mass/density is because mass is used when we are describing a discrete distribution, and density is used in the continuous case. In this example, it’s the pmf (a coin toss is a discrete experiment) that I’ll be talking about, however the same ideas hold for the PDF.
This is the CDF of the experiment above:
| \(P(X)\) |
CDF \(P(X <=x)\) |
| 0 |
0.25 |
| 1 |
0.75 |
| 2 |
1 |
As you may have noticed, the CDF is maxed out at one. 1 is the upper limit of the probability that an event from an experiment occurs - 0 is the lower limit. It is called cumulative because the probability distribution accumulates with each event. If you haven’t understood what that table is representing, let’s use our words!
- \(P(X=0)\) means that that probability of getting no heads is 0.25.
- \(P(X<=1)\) is \(\)P(X=1) + P(X=0)\(\). \(P(X=1)\) is \(TH\) and \(HT\) and therefore we’re adding 0.5 to the probability of getting \(TT\) which is 0.25, hence 0.75.
- \(P(X<=2)\) is just the probability of \(HH\) (0.25) + the previous 0.75, our final result being 1.
This is what the CDF looks like when we plot it
So can you guess what the PMF will look like? Hint: the pmf will describe the probability of each occurring coin toss .
| \(P(X)\) |
PMF \(P(X =x)\) |
| 0 heads |
0.25 |
| 1 heads |
0.5 |
| 2 heads |
0.25 |
If you sum up all the probabilities, they’ll add up to 1. So the PMF is showing us the probability of an event occurrence and CDF is showing us the probability of a range of events occuring. I know I keep on repeating this statement, but it’s common to not fully grasp the difference between the CDF and PMF and be unsure of their purpose. If you look hard at both, see you can go from the CDF to the PMF and vice versa.
So what happens if we’re dealing with continuous cases?
Well for starters, the PMF changes to a PDF. We are also usually presented with functions to represent the CDF and PDF. To find the CDF from the PDF, we integrate the PDF from \(-\infty\) to \(x\), where \(x\) is a placeholder variable.
I’m not going to show an example because at this point I think you should go back to the book but wait until this final concept.
We’ve mentioned that we have been generating uniform random variables using a PRNG. In many cases however, we would like to take these uniform random numbers and would like to make them follow some other kind of distribution. We want to transform them. The way to go about this is a technique known as the Inverse Transform method. The technique is very simple and very powerful:
Let’s say we have a random variable \(X\) , that has a CDF \(F(X)\). We want to generate values distributed according to this distribution. The steps to do this are:
- Generate a uniform random number u between \([0,1]\).
- Find the inverse of the CDF of \(F(X)\).
- We find X by computing \(F^{-1}(u)\). \(X\) is now distributed according to \(F(X)\).
The Inverse Transform method warrants its own blog post so I won’t go into detail about its intrinsics and its edge cases and so forth.
Go back to the book and come back right after you’ve obtained the inverse of the CDF.
We have computed a Monte Carlo estimation of an integral, and now we’ve computed the inverse cdf of a PDF, which means we can transform our uniform random numbers into the PDF that we selected. If you recall, we said that we draw our samples from a uniform distribution from 1 to 0 in our original definition of the Monte Carlo estimator. The PDF of this estimator is \(\frac{1}{1-0}\) which is \(1\). The more general Monte Carlo estimator definition is actually this:
\[\frac{1}{N} \sum_{i=0}^{N-1} \frac{f(X_i)}{p(X_i)}\]
Where \(p(X_i)\) is the PDF from which the samples are drawn. By selecting a PDF that matches the shape of the function that we are trying to estimate, we are weighting the samples so as to reduce the variance. This is known as Importance Sampling! Choosing a good PDF is an ongoing form of research. For our integral, the PDF Dr Shirley’s picked is \(\frac{1}{r}\).
For the moment, we’ve been drawing samples from the uniform distribution, but thanks to the inverse transform method, we’re now using these uniform numbers and transforming them to match the new PDF. We’ll then compute our original integral with these new random variables and divide by the new PDF.
Now would be a good time to finish the chapter.
If you feel more mathematically inclined, Alan Wolfe has a great blog post about One-Dimensional Monte Carlo Integration. He’s also got a plethora of posts that will have some common content with this blog post series. I would also suggest you have a look at PBRT Chapter 13 if you’re feeling brave!
If you remember, we spoke about stratification previously. Let’s take the original integral \(\int_0^2 x^2\). To stratify the points, we’ll divide the interval in 4 bins. If I am taking N samples, we are going to take \(\frac{n}{4}\) samples per bin, so let’s call this value \(k\). The Monte Carlo estimate using stratified sampling now looks like this:
\[\int_0^2 x^2 = (0.5 - 0)\frac{1}{k} \sum_{i=0}^{k} x_1^2 +
(1.0 - 0.5)\frac{1}{k} \sum_{i=0}^{k} x_2^2 +
\\
(1.5 - 1)\frac{1}{k} \sum_{i=0}^{k} x_3^2 +
(2 - 1.5)\frac{1}{k} \sum_{i=0}^{k} x_4^2\]
\(x_1\) is a random number between 0 and 0.5, \(x_2\) is between 0.5 and 1.0, \(x_3\) between 1.0 and 1.5, and \(x_4\) between 1.5 and 2, giving us a total of \(N\) samples.
Here is a self contained program showing the stratified and naive Monte Carlo estimations.
Stratification warrants its own post following some discussions with some friends. I wanted to show certain properties but felt that this post would be too long.
That’s pretty much it for this post, next up is Chapter 3 and 4.

HI all,
I have been playing around with the new EmonCMS v9.1 and am loving it so far. Have been able to get it to subscribe to my MQTT feeds quite easily. However it is not able to extract all the csv data in the MQTT message.
Could someone please let me know what i have done wrong or point me to another post / documentation which i have missed. Thanks.
Details below:
EmonCMS:
EmonHub Log Extract:

Re: [EmonCMS v9] MQTT - How to split up values?
After digging through the source code I was able to modifiy the EmonHubMqttInterfacer.py in the emonhub and I removed the title called values from the publish to mqtt function:
This has resolved my issue and now all of my data is reported on separate inputs. I can go through and update the code of this to be a little bit more robust (take the node definition from the config file and publish against that in mqtt); however i assume this has already been done. If so can anyone point me to some documentation regarding installation of the newer version?
Thanks in advance all
Re: [EmonCMS v9] MQTT - How to split up values?
Without any code changes, a default emoncms v9 installation will split up the MQTT values, provided that you don't add any text to the message. (the format as described in the installation guide)
If you publish to rx/10 your list of comma limited values such as 300,167,996,199 emoncms will split them into;
Node Key Value
10 0 300
10 1 167
10 2 996
10 3 199
You can then name the inputs in emoncms accordingly.

Not so Jolley Michael left Grimsby in wake of radio rant says club director
Manager left his post last Friday.
Michael Jolley’s foul-mouthed tirade towards local journalists played a part in him losing his job as Grimsby manager, majority shareholder John Fenty has revealed.
The Mariners announced on Friday that Jolley, 42, had left the club by mutual consent following the Sky Bet League Two club’s seven-game winless run.
But Fenty has confirmed in an interview with Grimsby’s official website that the club had been forced to take action after a recording of an expletive-laden rant at BBC Humberside journalists last month had been leaked on social media.
“Radio Humberside had complained to directors and given that we had now seen the footage and listened to what was said, it is a matter of fact that the club would need to take disciplinary proceedings,” Fenty said.
“The (club’s) investigation found there was a need for a disciplinary hearing, which was planned to be held last Friday.”
Fenty said he had been approached by Jolley the previous Wednesday, adding: “His view was he knew where this was going and he sought an opportunity for a compromise arrangement, which resulted leaving on mutual grounds.
“Clearly he wasn’t sacked. We’re really disappointed in the whole affair, Michael knows that.”
Fenty said he was also disappointed Jolley had asked BBC Radio Humberside to question the club’s playing budget.
“In the light of things, when things aren’t going well on the field, it is a pressure-cooker and we do tend to give allowance for some of these things that erupt over,” he said.
“But on the scale of eruption, it’s clear that the football club had to go through a disciplinary process and anybody who thinks otherwise needs to think again.
“I’m not suggesting it would have resulted in gross misconduct and dismissal, there can be a whole range of outcomes to that.
“But at the end of the day Michael assumed it could only go in one direction and sought mutual settlement, which we arrived at.”
Jolley’s outburst followed the Mariners’ 4-0 home defeat to Leyton Orient on October 19 and is reported to have included 58 swear words in a four-minute rant.
“You are a f***ing disgrace of a journalist,” Jolley appeared to say in one of the leaked clips. “The f***ing radio station gives us f***ing no positive coverage whatsoever.”
Fenty said he had “had his problems with BBC Radio Humberside in the past”, but had been “shocked and stunned” at Jolley’s behaviour.
“It’s a serious tirade,” he added. “When you’ve just lost 4-0 it’s not the right time to pick a fight with a radio station.”
The BBC said it was a matter for the club, but it is understood no official complaint was made to Grimsby. Jolley was not willing to comment at this stage when contacted by the PA news agency.
