He rose through the ranks of contributors quickly with the great implementation of Routes, but has since put his mark on so much more. Including the dependency management system and lots of other tricky parts of Rails. In the just released 0.13, he was single-handedly responsible for about a quarter of the patches going in.
 It’s due time that he was granted the ability to do so himself.
Please do welcome Nicholas Seckar of Toronto, Canada as the latest member of the commit team. He joins Jeremy Kemper, Jamis Buck, and myself.
Can you believe that this guy actually has availability in his calendar to take on new projects? It’s true. So if you’re looking to hire a freelancer that really knows Rails, this is a great opportunity. Write him at nseckar at gmail dot com.


Man threatened to burn down nightclub because it didn't sell Red Bull
A man has been jailed after he threw a petrol canister and flicked a lighter at a nightclub full of people because it didn’t sell Red Bull.
Michael Day, 38, screamed ‘I’m going to burn every last one of you’ before Shush nightclub, in Wantage, Oxfordshire, had to be evacuated.
Day, of Wantage, was set to stand trial for the incident but later admitted attempted arson and two counts of making threats to kill.
He descended into an explosive rage after bar staff had served him an alternative drink, as they didn’t sell Red Bull, on April 28, heard Oxford Crown Court.
Day became aggressive and was thrown out of the club – where he had already been banned on another occasion – and went home.

As he got near to the club entrance he was seen throwing it towards the door and launching himself in the path of door staff.
Petrol was spilt on the ground and over the clothing of staff members, before Day flicked a lighter and screamed death threats, heard the court.
Day, who also had a cigarette in his mouth, shouted racist abuse towards one worker and threatened to burn the club down.
He shouted: ‘I am going to burn every last one of you’ and he said he would ‘burn them all’.
As the smell of the fumes wafted inside the club, all 177 party-goers had to be evacuated.
Day was arrested and he told officers he had drank up to seven Corona bottles and never intended to start a fire but wanted to ‘scare people’.
In mitigation, his defence barrister said Day couldn’t remember the incident.
Judge Maria Lamb called the episode ‘terrifying’ and jailed him for five years and two months.

Disentangling 3D Prototypical Networks For Few-Shot Concept Learning
Abstract
We present neural architectures that disentangle RGB-D images into objects’ shapes and styles and a map of the background scene, and explore their applications for few-shot 3D object detection and few-shot concept classification. Our networks incorporate architectural biases that reflect the image formation process, 3D geometry of the world scene, and shape-style interplay. They are trained end-to-end self-supervised by predicting views in static scenes, alongside a small number of 3D object boxes. Objects and scenes are represented in terms of 3D feature grids in the bottleneck of the network. We show that the proposed 3D neural representations are compositional: they can generate novel 3D scene feature maps by mixing object shapes and styles, resizing and adding the resulting object 3D feature maps over background scene feature maps. We show that classifiers for object categories, color, materials, and spatial relationships trained over the disentangled 3D feature sub-spaces generalize better with dramatically fewer examples than the current state-of-the-art, and enable a visual question answering system that uses them as its modules to generalize one-shot to novel objects in the scene
Overview of D3DP-Nets
Given a single image-language example regarding new concepts (e.g., blue and carrot), our model can parse the object into its shape and style codes and ground them with Blue and Carrot labels, respectively. On the right, we show tasks the proposed model can achieve using this grounding.(a) It can detect the object under novel style, novel pose, and in novel scene arrangements and viewpoints. (b) It can detect a new concept like blue broccoli. (c) It can imagine scenes with the new concepts. (d) It can answer complex questions about the scene.
Architecture for disentangling 3D prototypical networks (D3DP-Nets). (a) Given multi-view posed RGB-D images of scenes as input during training, our model learns to map a single RGB-D image to a completed scene 3D feature map at test time, by training for view prediction. From the completed 3D scene feature map, our model learns to detect objects from the scene. (b) In each 3D object box, we apply a shape-style disentanglement autoencoder that disentangles the object-centric feature map to a 3D (feature) shape code and a 1D style code. (c) Our model can compose the disentangled representations to generate a novel scene 3D feature map. We urge the readers to refer the video on the project page for an intuitive understanding of the architecture.

The Life-Cycle of Merge Conflicts: Processes, Barriers, and Strategies
Nicholas Nelson, Caius Brindescu, Shane McKee, Anita Sarma, Danny Dig.
Merge conflicts occur when developers make concurrent changes to the same part of the code. They are an inevitable and disruptive aspect of collaborative software development. Thus tool builders and researchers have focused on the prevention and automatic resolution of merge conflicts. However, there is little empirical knowledge about how developers actually monitor for merge conflicts and plan, perform, and evaluate resolutions. Without such knowledge, tool builders might be building on the wrong assumptions and researchers might miss opportunities for improving the state of the art.
We conducted semi-structured interviews with 10 software developers across 7 organizations, including both open-source and commercial projects. We identify key processes, techniques, and perceptions from developers, which we extend and validate via two surveys, a Processes Survey and a Barriers Survey, of 102 and 162 developers, respectively.
Among others, we find that developers rely on reactive strategies of monitoring for merge conflicts. We find that developers defer responding to conflicts based on their perception of the complexity of the conflicting code and that deferring affects the workflow of the entire team. Developers also rely on this perception to visually evaluate their merge conflict resolutions for correctness. Finally, developers' perceptions alter the impact of tools and processes designed to preemptively and efficiently resolve merge conflicts. Understanding their processes and perceptions can help design human-oriented tools that better support their individual development processes.

FluidGrid allows to set up a nice tight grid with items that have variable heights and widths.
FluidGrid is a responsive grid. That means, the grid will reflow as the window size changes.
Items can have any content: text, images, links, input fields, etc.
They can be defined in a static or in a dynamic way as in data iteration components.
This example demonstrates a simple usage with static items. Static items are defined by
the tag pe:fluidGridItem which can be placed multiple times below
the main tag pe:fluidGrid. Items can have different width / height
specified by style classes. The main container for the pe:fluidGrid
has the style class pe-fluidgrid and the container of the pe:fluidGridItem
has the style class pe-fluidgrid-item.
In the example we used two attributes hGutter
and vGutter for horizontal and vertical space between items.

First, get all the files, either as a zip archive or a gzipped tar-file and unpack them. Now, start up Matlab (version 5 or higher). Make
sure that the toolbox is in your path. This can be done simply by
cd
'ing to the correct directory.
Alternatively,
if you have unpacked them into
directory /users/rich/m_map
(and /users/rich/m_map/private
),
then you can add this to your search path:
path(path,'/users/rich/m_map');or
addpath /users/rich/m_mapTo follow along with this document, you would then use a Web-browser to open
file:/users/rich/m_map/map.html
, that
is, this HTML document.
(Note: you may want to install M_Map as a toolbox accessible to all users. To do this, unpack the files into $MATLAB/toolbox/m_map, and add that directory to the list defined in $MATLAB/toolbox/local/pathdef.m).
To see an example map, try this:
m_proj('oblique mercator'); m_coast; m_grid;This is a line map of the Oregon/British Columbia coast, using an Oblique Mercator projection (A few more complex maps can be generated by running the demo function
m_demo
).
The first line initializes the projection. Defaults are set for the different projection, so you can easily see what a specific projection looks like, but all projections have a number of optional parameters as well. To get the same map without using the defaults, you would use
m_proj('oblique mercator','longitudes',[-132 -125], ... 'latitudes',[56 40],'direction','vertical','aspect',.5);The exact meanings of the various options is given in Section 2 . However, notice that longitudes are specified using a signed notation - East longitudes are positive, whereas West longitudes are negative (Also note that a decimal degree notation is used, so that a longitude of 120 30'W is specified as -120.5).
The second line draws a coastline, using the 1/4 degree database. Coastlines with greater
resolution can be drawn, using your own database (see also Section 7 ). m_coast
can be called with various line parameters. For example,
m_coast('linewidth',2,'color','r');draws a thicker red coastline. Filled coastlines can also be drawn, using the
'patch'
option (followed by any of the usual PATCH property/value pairs).
m_coast('patch',[.7 .7 .7],'edgecolor','none');draws a coastline with a gray fill and no border.
The third line superimposes a grid. Although there are many possible options that can be used to customize the appearance of the grid, defaults can always be used (as in the example). These options are discussed in Section 4 . You can get a list of the options using the GET syntax:
m_grid getwhich acts somewhat like the
get(gca)
syntax for regular plots.
Finally, suppose you want to show and label the location of, say, a mooring at 129W, 48 30'N.
[X,Y]=m_ll2xy(-129,48.5); line(X,Y,'marker','square','markersize',4,'color','r'); text(X,Y,' M5','vertical','top');
m_ll2xy
(and its inverse m_xy2ll
) convert from longitude/latitude coordinates to those of the
projection. Various clipping options can also be specified in converting to projection
coordinates.
Finally, we may want to alter the grid details slightly. Note that, a given map must only be initialized once.
clf m_coast('patch',[.7 .7 .7],'edgecolor','none'); m_grid('xlabeldir','end','fontsize',10); [X,Y]=m_ll2xy(-129,48.5); line(X,Y,'marker','square','markersize',4,'color','r'); text(X,Y,' M5','vertical','top');
In order to get a list of the current projections,
m_proj getor
m_proj('get');Which currently return the following list:
Available projections are: Stereographic Orthographic Azimuthal Equal-area Azimuthal Equidistant Gnomonic Satellite Albers Equal-Area Conic Lambert Conformal Conic Mercator Miller Cylindrical Equidistant Cylindrical Oblique Mercator Transverse Mercator SinusoidalIf you want details about the possible options for any of these projections, add its name to the above command, e.g.
m_proj('get','stereographic'); 'Stereographic' <,'lon<gitude>',center_long> <,'lat<itude>', center_lat> <,'rad<ius>', ( degrees | [longitude latitude] )> <,'rec<tbox>', ( 'on' | 'off' )>You can also get details about the current projection. For example, in order to see what the default parameters are for the sunusoidal projection, we first initialize it, and then use the
'set'
option:
m_proj('sinusoidal'); m_proj set Current mapping parameters - Projection: Sinusoidal (function: mp_tmerc) longitudes: -125 -122 (centered at -123.5) latitudes: 47 51 Rectangular border: offIn order to initialize a projection, you usually specify some location parameters that define the geometry of the projection (longitudinal limits, central parallel, etc.), as well as parameters that define the extent of the map (whether it is in a rectangular axis, what the border points are, etc.). These vary slightly from projection to projection. Two useful properties for projections are (1) the ability the preserve angles for differentially small regions, and (2) the ability to preserve area. Projections satisfying the first condition are called conformal , thos satisfying the second are called equal-area . No projection can be both. Many projections (especially global projections) are neither, instead and attempt has been made to balance the errors in both for aesthetic reasons. Note: All projections are currently spherical rather than ellipsoidal. It is unlikely that this will be a problem in normal usage.

M_Map includes two fairly simple databases for coastlines and global elevation data. Highly-detailed databases are not included in this release because they are a) extremely large and b) extremely time-consuming to process (loops are inherently involved). If more detailed maps are required, section 7 and section 8 give instructions on how to proceed.
M_Map includes a 1/4 degree resolution coastline database. This is suitable for maps
covering large portions of the globe, but is noticeably coarse for many large-scale
applications. Users not satisfied with their regional map are directed to
section 7 for more information on creating and using high-resolution
coastlines.
The M_Map database is accessed using the m_coast
function. Coastlines
can be drawn as simple lines, using
m_coast('line', ...optional line arguments );or
m_coast( optional line arguments );where the optional arguments are all the standard arguments for specifying line style, width, color, etc. Coastlines can also be drawn as filled patches using
m_coast('patch', ...optional patch arguments );where the optional trailing arguments are the standard patch properties. For example,
m_coast('patch',[.7 .7 .7],'edgcolor','g');draws gray land, outlined in green. When patches are being drawn, lakes and inland seas are given the axes background colour.
Note that line coastlines are usually drawn rather rapidly. Filled coastlines take considerably more time to generate (because map limits are not necessarily rectangular, clipping must be accomplished in m-files.
M_Map can access a 1-degree resolution global elevation database (actually, this database is
is included in the Matlab distribution, used by of
The purpose of this package is to allow you to map your own data! Once a suitable
grid and (possibly) a coastline have been chosen, raw longitude/latitude coordinates
must be converted to projection coordinates before being plotted. Similarly, an
program using, say,
Once the conversion of coordinates has taken place, plotting of data using
any of the standard Matlab functions (line, patch, pcolor, etc.) proceeds as usual.
Caution: One problem that sometimes occurs is that data does not appear on the plot due to
ambiguities in longitude values. For example, if plot longitude limits are [-180 180],
a point with a longitude of, say, 200, may not appear in cylindrical and conic projections.
This is not a bug. Handling the clipping in "wrapped around" curves requires
adding points (rather than just moving them) and is therefore incompatible with
various other requirements (such as keeping input and output matrices the same size
in the conversion routines described below).
For ideas on how to make more complex plots, see the Examples.
These plots are also included in the function

).
A contour map of elevations at default levels can be drawn using
m_elev;
Different levels can also be specified:
m_elev('contour',LEVELS, optional contour arguments);
Filled contours are also possible:
m_elev('contourf',LEVELS, optional contourf arguments);
4. Customizing axes
4.1 Grid lines and labels
In order to get the perfect grid, you may want to experiment with different grid options. Two
functions are useful here, M_GRID which draws a grid, and M_UNGRID which erases the current
grid (but leaves all coastlines and user-specified data alone). Try
m_proj('Lambert');
m_coast;
m_grid;
to get a Lambert conic projection of North America. Now try
m_ungrid
The coastline is still there, but the grid has disappeared and the axes shows raw X/Y projection
coordinates. Now, try this:
m_grid('xtick',10,'tickdir','out','yaxislocation','right','fontsize',7);
The various options that can be changed are:
This specifies whether or not an outline box is drawn.
'box',( 'on' | 'off' )
This specifies the number/location of the longitude grid. If a single number is specified,
grid lines/values are drawn for approximately that number of equally-spaced locations (the
number is only approximate because the M_GRID attempts to find "nice" intervals, i.e. it
rounds to even increments). Exact locations can be specified by using a vector of
location values. There is an analagous 'xtick',( num | [value1 value2 ...])
'ytick'
property.
Special labels can be specified. Labels can either be numerical values (which are then formatted
by M_GRID), or string values which are used without change. There is an analagous
'xticklabels',[label1;label2 ...]
'yticklabels'
property
Longitude labels are either middled onto the ends of their prespective grid lines (and drawn
perpendicular to those lines), or are drawn extending outwards fro the ends of those lines.
There is an analagous
'xlabeldir', ( 'middle' | 'end' )
'ylabeldir'
property.
Specifies the length of tickmarks (as a fraction of plot width)
'ticklen',value
Specifies whether ticksmarks point inwards or outwards.
'tickdir',( 'in' | 'out' )
Specify various line/text properties for the grid and its labels.
'color',colorspec
'linewidth', ( value | 'none' )
'linestyle',linespec
'fontsize',value
'fontname',name
Specifies where the X-axis will be drawn, either at the bottom (southermost) end, at
the top (northernmost) end, or in the middle.
'XaxisLocation',( 'bottom' | 'middle' | 'top' )
Specifies where the Y-axis will be drawn, either at the left (westernmostmost) end, at
the right (easternmost) end, or in the middle.
'YaxisLocation',( 'left' | 'middle' | 'right' )
4.2 Titles and x/ylabels
Titles and x/ylabels can be added to maps using the title
and
x/ylabel
functions in the usual way (this is a change from v1.0 in which
the 'visible' property had
to be explicitly set to 'on'; this is now done within m_grid).
5. Adding your own data
ginput
to select points will have to convert projection coordinates
back to longitude/latitude.
5.1 Converting longitude/latitude to projection coordinates
The following command converts longitude/latitude coordinates to projection coordinates.
[X,Y]=m_ll2xy(LONG,LAT, ...optional clipping arguments )
where LONG, LAT, X, and Y are matrices of the same size. The possible clipping arguments are
This is the default. Columns of LONG and LAT are assumed to form lines, and these are clipped
to the map limits. The first point outside the map is therefore moved to the map edge,
and all other points are converted the NaN.
'clip','on'
No clipping is performed. This is sometimes useful for debugging purposes.
'clip','off'
Points are tested against the map limits. Those outside the limits are converted to NaN,
those inside are converted to projection coordinates. No points are moved. This option
is useful for point data (such as station locations).
'clip','point'
Points are tested against the map limits. Those outside the limits changed into a point exactly
on the limits. Those inside are converted to projection coordinates. This option
may be useful when trying to draw patches, however it probably won't work well.
'clip','patch'
5.2 Converting projection coordinates to longitude/latitude
Conversion from projection coordinates to longitude/latitude is straightforward:
[LONG,LAT]=m_ll2xy(X,Y)
There are no options.
6. More complex plots
m_demo
.
7. Adding your own coastlines
m_coast
, the best procedure is to
One place where high-resolution coastline data can be obtained is
The Coastline Extractor.
Follow the instructions there to get coastline data in a matlab-readable file,
and download to your computer. If the file is saved as "coast.dat", you can
plot it (as lines) using the following:
m_ll2xy
, and plot.
load coast.dat
[X,Y]=m_ll2xy(coast(:,1),coast(:,2));
line(X,Y);
Filled coastlines will require more work. You should first read the instructions there
on joining the coastline data into continuous segments. If you are lucky,
(i.e. no lakes or anything else), you may achieve success with
load coast.dat
[X,Y]=m_ll2xy(coast(:,1),coast(:,2),'clip','patch');
k=[find(isnan(X(:,1)))];
for i=1:length(k)-1,
x=coast([k(i)+1:(k(i+1)-1) k(i)+1],1);
y=coast([k(i)+1:(k(i+1)-1) k(i)+1],2);
patch(x,y,'r');
end;
If this does not work, read the comments in m_coast
, orient the curves
in the desired fashion, and modify m_coast
to load your own data
instead of m_coasts.mat
.
8. Adding your own topography/bathymetry
m_elev
to make use this data should be straightforward.

The routines documented here compute the three-dimensional discrete Fourier transforms (DFT) of a three-dimensional array of complex numbers in either single or double precision arithmetic. The 3D DFT is computed using a highly-efficient FFT algorithm.
Please note that at Release 2.7 of ACML it was necessary to modify
slightly the interfaces of two of the expert FFT drivers introduced at
Release 2.2 of ACML. The two routines are CFFT3DX
and ZFFT3DX
.
The changes were required to permit the optimization of these routines by
adding an initialization stage which can then use the plan generator
(MODE=100) to select the optimal plan. User codes that called CFFT3DX
or ZFFT3DX
using a release of ACML prior to 2.7 will need to be modified
in one of two ways. Calls to CFFT3DX
/ZFFT3DX
with

PLANET SICK-BOY: http://www.sick-boy.com "We Put the SIN in Cinema"
The ads for Jim Carrey's new film announce he's going `from gentle to mental.' The slogan refers to Carrey's character in Me, Myself & Irene, the new comedy from the dick/shit joke factory known as the Farrelly brothers, but it could just as easily apply to the $20 million man's decision to sign on to Irene. He's reverted from (near) Oscar-worthy performances to the type of hyperactive, lowbrow comedy that made him a star.
In Irene, Carrey (Man on the Moon) plays Charlie, a well-adjusted Rhode Island State Trooper complete with typical cop moustache. Described as a really nice guy, Charlie also has a beautiful girlfriend named Layla (Traylor Howard, Two Guys and a Girl), and the film opens with the happy couple getting hitched.
But that's just the tip of the iceberg, as far as Charlie's troubles are concerned. Nobody takes him seriously, from the neighbor that steals his newspaper, to his co-workers, to the citizens he's supposed to serve and protect. Oh, and there's the little matter of the severely tanned triplets that Layla has given birth to. Their names are Jamal, Lee Harvey and Shonte, Jr. - you do the math. Layla eventually leaves Charlie and the kids to live alone in their garage-sized house.
As a result of the entire world walking all over him, Charlie develops another personality - a rude, no-nonsense bad-ass named Hank - that emerges in a very funny scene set in a supermarket. As you can imagine, Carrey plus a split personality equals a lot of nifty physical comedy that nobody else in the world would be able to pull off. There's a scene toward the end where Charlie is fighting Hank (or vice-versa), and Carrey does such a good job, it almost looks fake.
Unfortunately, Irene doesn't quite measure up to any of the three previous Farrelly brothers' films (There's Something About Mary, Kingpin and Carrey's Dumb and Dumber). The main problem is with a convoluted storyline involving a woman named Irene (Renée Zellweger, The Bachelor) who Charlie/Hank must escort from Rhode Island to Massena, New York. Irene is embroiled in some sort of big business/police cover-up deal that's way too detailed for this kind of film. And there are no bust-your-gut-laughing scenes, like the Stiller vs. Dog set piece in Mary.
As a result, the film is flat in too many spots, and wastes time setting up its unnecessarily complicated plot when it could have had more gags about feces and urine. Irene was originally supposed to be about Siamese twins (played by Carrey and Woody Allen) that fall for the same girl, but that idea was scrapped when Allen didn't sign on to the project. The Farrellys dusted off an old script that they co-wrote with an old friend (Mike Cerrone - he plays a police officer, too).
 But the Farrellys are equal opportunity offenders and leave no stone unturned. They mock blacks, albinos, lesbians and just about any other group you can attach a name to. And there are sight gags a-plenty (like Charlie crammed onto the couch with his three gigantic black sons), which leaves Zellweger as the straight man in all of her scenes with her real-life beau Carrey (I think she sets some kind of film record for the most number of horror-struck double takes).
Irene is narrated by Rex Allen, Jr., who, like William Preston Robertson in Raising Arizona and Sam Neill in The Big Lebowski, uses a slow Southern drawl to tell the story via flashback. The film also features cameo appearances by tennis pin-up princess Anna Kournikova and former Boston Bruin puck-head Cam Neely. Sadly, Farrelly staple Lin Shaye (she's the one who French-kissed the dog in Mary) appears briefly in only one scene.

This curriculum aims towards evolving a sense of how an individual can develop the essential skills in order to manage, develop and effectively utilise the available human resource in an organisation. This is will be done through a 4-week fellowship program which will include multiple sessions revisiting the history and fundamentals of Human Resource Management and which would ultimately penetrate the concurrent issues faced by an organization regarding its human resource. Apart from the knowledge sessions, there will be multiple interactive sessions and activities which will give all the participants a chance to apply the theoretical knowledge they gain into a practical sphere. Along with this, the participants will be required to identify one contemporary HR Management issue (gender diversity, non-monetary incentivisation, cultural diversity, age diversity, etc.) and prepare a case study/dissertation on it.


This document will teach you how to do a basic export. To do a more advanced export check out exporting options .
To perform a basic export, select File>Export>Wavefront OBJ, leave all options as default and click Export!
TIP : Want to export one object and have it centered when you import it to your 3D application? Untick "Apply Position"


thMessagePath
Thymol uses the thMessagePath to determine the location of properties files that contain the default externalised messages for a template.
The value of thMessagePath should be the location of the template file directory relative to the current template path.
By default, the externalised messages files are named "Messages.properties" or "Messages(suffix).properties".
In the second form (suffix) represents an optional locale specification in the form "_ll_CC-vv". Here, "ll" is a specifier for language, "CC" an optional country and "vv" an optional variant.
You can change the name used when searching for messages files by setting the value of the thMessagesBaseName control variable.

java.lang.Object javax.sql.rowset.spi.SyncFactory
public class SyncFactory
The Service Provider Interface (SPI) mechanism that generates SyncProvider
instances to be used by disconnected RowSet
objects.
The SyncProvider
instances in turn provide the
javax.sql.RowSetReader
object the RowSet
object
needs to populate itself with data and the
javax.sql.RowSetWriter
object it needs to
propagate changes to its
data back to the underlying data source.
Because the methods in the SyncFactory
class are all static,
there is only one SyncFactory
object
per Java VM at any one time. This ensures that there is a single source from which a
RowSet
implementation can obtain its SyncProvider
implementation.
SyncFactory
class provides an internal registry of available
synchronization provider implementations (SyncProvider
objects).
This registry may be queried to determine which
synchronization providers are available.
The following line of code gets an enumeration of the providers currently registered.
java.util.Enumeration e = SyncFactory.getRegisteredProviders();All standard
RowSet
implementations must provide at least two providers:
CachedRowSet
implementation
or an implementation derived from it
WebRowSet
objects
SyncProvider
implemtations RIOptimisticProvider
and RIXmlProvider
,
which satisfy this requirement.
The SyncFactory
class provides accessor methods to assist
applications in determining which synchronization providers are currently
registered with the SyncFactory
.
Other methods let RowSet
persistence providers be
registered or de-registered with the factory mechanism. This
allows additional synchronization provider implementations to be made
available to RowSet
objects at run time.
Applications can apply a degree of filtering to determine the level of
synchronization that a SyncProvider
implementation offers.
The following criteria determine whether a provider is
made available to a RowSet
object:
RowSet
object, and
the SyncFactory
does not contain a reference to this provider,
a SyncFactoryException
is thrown stating that the synchronization
provider could not be found.
RowSet
implementation is instantiated with a specified
provider and the specified provider has been properly registered, the
requested provider is supplied. Otherwise a SyncFactoryException
is thrown.
RowSet
object does not specify a
SyncProvider
implementation and no additional
SyncProvider
implementations are available, the reference
implementation providers are supplied.
SyncProvider
Implementations
Both vendors and developers can register SyncProvider
implementations using one of the following mechanisms.
-Drowset.provider.classname=com.fred.providers.HighAvailabilityProvider
#Default JDBC RowSet sync providers listing # # Optimistic synchronization provider rowset.provider.classname.0=com.sun.rowset.providers.RIOptimisticProvider rowset.provider.vendor.0=Sun Microsystems Inc rowset.provider.version.0=1.0 # XML Provider using standard XML schema rowset.provider.classname.1=com.sun.rowset.providers.RIXMLProvider rowset.provider.vendor.1=Sun Microsystems Inc. rowset.provider.version.1=1.0The
SyncFactory
checks this file and registers the
SyncProvider
implementations that it contains. A
developer or vendor can add other implementations to this file.
For example, here is a possible addition:
rowset.provider.classname.2=com.fred.providers.HighAvailabilityProvider rowset.provider.vendor.2=Fred, Inc. rowset.provider.version.2=1.0
SyncFactory
will attempt to load
SyncProvider
implementations from that JNDI context.
For example, the following code fragment registers a provider implementation
on a JNDI context. This is something a deployer would normally do. In this
example, MyProvider
is being registered on a CosNaming
namespace, which is the namespace used by J2EE resources.
import javax.naming.*; Hashtable svrEnv = new Hashtable(); srvEnv.put(Context.INITIAL_CONTEXT_FACTORY, "CosNaming"); Context ctx = new InitialContext(svrEnv); com.fred.providers.MyProvider = new MyProvider(); ctx.rebind("providers/MyProvider", syncProvider);
SyncFactory
instance. This allows the SyncFactory
to browse within the JNDI context looking for SyncProvider
implementations.
Hashtable appEnv = new Hashtable(); appEnv.put(Context.INITIAL_CONTEXT_FACTORY, "CosNaming"); appEnv.put(Context.PROVIDER_URL, "iiop://hostname/providers"); Context ctx = new InitialContext(appEnv); SyncFactory.registerJNDIContext(ctx);If a
RowSet
object attempts to obtain a MyProvider
object, the SyncFactory
will try to locate it. First it searches
for it in the system properties, then it looks in the resource files, and
finally it checks the JNDI context that has been set. The SyncFactory
instance verifies that the requested provider is a valid extension of the
SyncProvider
abstract class and then gives it to the
RowSet
object. In the following code fragment, a new
CachedRowSet
object is created and initialized with
env, which contains the binding to MyProvider
.
Hashtable env = new Hashtable(); env.put(SyncFactory.ROWSET_SYNC_PROVIDER, "com.fred.providers.MyProvider"); CachedRowSet crs = new com.sun.rowset.CachedRowSetImpl(env);Further details on these mechanisms are available in the
javax.sql.rowset.spi
package specification.

Property Binding
An object's property can be assigned a static value which stays constant until it is explicitly assigned a new value. However, to make the fullest use of QML and its built-in support for dynamic object behaviors, most QML objects use property bindings.
Property bindings are a core feature of QML that lets developers specify relationships between different object properties. When a property's dependencies change in value, the property is automatically updated according to the specified relationship.
Behind the scenes, the QML engine monitors the property's dependencies (that is, the variables in the binding expression). When a change is detected, the QML engine re-evaluates the binding expression and applies the new result to the property.
Overview
To create a property binding, a property is assigned a JavaScript expression that evaluates to the desired value. At its simplest, a binding may be a reference to another property. Take the following example, where the blue Rectangle's height is bound to the height of its parent:
Rectangle { width: 200; height: 200 Rectangle { width: 100 height: parent.height color: "blue" } }
Whenever the height of the parent rectangle changes, the height of the blue rectangle automatically updates to be of the same value.
A binding can contain any valid JavaScript expression or statement, as QML uses a standards compliant JavaScript engine. Bindings can access object properties, call methods and use built-in JavaScript objects such as Date
and Math
. Below are other possible bindings for the previous example:
height: parent.height / 2 height: Math.min(parent.width, parent.height) height: parent.height > 100 ? parent.height : parent.height/2 height: { if (parent.height > 100) return parent.height else return parent.height / 2 } height: someMethodThatReturnsHeight()
Below is a more complex example involving more objects and types:
Column { id: column width: 200 height: 200 Rectangle { id: topRect width: Math.max(bottomRect.width, parent.width/2) height: (parent.height / 3) + 10 color: "yellow" TextInput { id: myTextInput text: "Hello QML!" } } Rectangle { id: bottomRect width: 100 height: 50 color: myTextInput.text.length <= 10 ? "red" : "blue" } }
In the previous example,
topRect.width
depends onbottomRect.width
andcolumn.width
topRect.height
depends oncolumn.height
bottomRect.color
depends onmyTextInput.text.length
Syntactically, bindings are allowed to be of arbitrary complexity. However, if a binding is overly complex - such as involving multiple lines, or imperative loops - it could indicate that the binding is being used for more than describing property relationships. Complex bindings can reduce code performance, readability, and maintainability. It may be a good idea to redesign components that have complex bindings, or at least factor the binding out into a separate function.
Creating Property Bindings from JavaScript
A property with a binding is automatically updated as necessary. However, if the property is later assigned a static value from a JavaScript statement, the binding will be removed.
For example, the Rectangle below initially ensures that its height
is always twice its width
. However, when the space key is pressed, the current value of width*3
will be assigned to height
as a static value. After that, the height
will remain fixed at this value, even if the width
changes. The assignment of the static value removes the binding.
import QtQuick 2.0 Rectangle { width: 100 height: width * 2 focus: true Keys.onSpacePressed: { height = width * 3 } }
If the intention is to give the rectangle a fixed height and stop automatic updates, then this is not a problem. However, if the intention is to establish a new relationship between width
and height
, then the new binding expression must be wrapped in the Qt.binding() function instead:
import QtQuick 2.0 Rectangle { width: 100 height: width * 2 focus: true Keys.onSpacePressed: { height = Qt.binding(function() { return width * 3 }) } }
Now, after the space key is pressed, the rectangle's height will continue auto-updating to always be three times its width.
Using this
with Property Binding
When creating a property binding from JavaScript, the this
keyword can be used to refer to the object which receives the binding. This is helpful for resolving ambiguities with property names.
For example, the Component.onCompleted
handler below is defined within the scope of the Item. In this scope, width
refers to the Item's width, not the Rectangle's width. To bind the Rectangle's height
to its own width
, the binding expression must explicitly refer to this.width
(or alternatively, rect.width
):
Item { width: 500 height: 500 Rectangle { id: rect width: 100 color: "yellow" } Component.onCompleted: { rect.height = Qt.binding(function() { return this.width * 2 }) console.log("rect.height = " + rect.height) // prints 200, not 1000 } }
Note: The value of this
is not defined outside of property bindings. See JavaScript Environment Restrictions for details.

FeathersJS Auth Recipe：自定义身份验证策略¶
The Auk release of FeathersJS includes a powerful new authentication suite built on top of PassportJS. The new plugins are very flexible, allowing you to customize nearly everything. We can leverage this to create completely custom authentication strategies using Passport Custom. Let’s take a look at two such examples in this guide.
Setting up the basic app¶
Let’s first start by creating a basic server setup.
const feathers = require('@feathersjs/feathers');
const express = require('@feathersjs/express');
const auth = require('@feathersjs/authentication');
const jwt = require('@feathersjs/authentication-jwt');
const memory = require('feathers-memory');
const app = express(feathers());
app.configure(express.rest());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.configure(auth({ secret: 'secret' }));
app.configure(jwt());
app.use('/users', memory());
app.hooks({
before: {
all: [auth.hooks.authenticate('jwt')]
}
});
app.listen(8080);
Creating a Custom API Key Auth Strategy¶
The first custom strategy example we can look at is an API Key Strategy. Within it, we’ll check if there is a specific header in the request containing a specific API key. If true, we’ll successfully authorize the request.
First let’s make the strategy using
`passport-custom
<https://www.npmjs.com/package/passport-custom>`_
npm package.
const Strategy = require('passport-custom');
module.exports = opts => {
return function() {
const verifier = (req, done) => {
// get the key from the request header supplied in opts
const key = req.params.headers[opts.header];
// check if the key is in the allowed keys supplied in opts
const match = opts.allowedKeys.includes(key);
// user will default to false if no key is present
// and the authorization will fail
const user = match ? 'api' : match;
return done(null, user);
};
// register the strategy in the app.passport instance
this.passport.use('apiKey', new Strategy(verifier));
// Add options for the strategy
this.passport.options('apiKey', {});
};
};
Next let’s add this to our server setup
const apiKey = require('./apiKey');
app.configure(
apiKey({
// which header to look at
header: 'x-api-key',
// which keys are allowed
allowedKeys: ['opensesame']
})
);
Next let’s create a custom authentication hook that conditionally applies auth for all external requests.
const commonHooks = require('feathers-hooks-common');
const authenticate = () =>
commonHooks.iff(
// if and only if the request is external
commonHooks.every(commonHooks.isProvider('external')),
commonHooks.iffElse(
// if the specific header is included
ctx => ctx.params.headers['x-api-key'],
// authentication with this strategy
auth.hooks.authenticate('apiKey'),
// else fallback on the jwt strategy
auth.hooks.authenticate(['jwt'])
)
);
app.hooks({
before: {
all: [authenticate()]
}
});
Finally our server.js
looks like this:
const feathers = require('@feathersjs/feathers');
const express = require('@feathersjs/express');
const auth = require('@feathersjs/authentication');
const jwt = require('@feathersjs/authentication-jwt');
const memory = require('feathers-memory');
const commonHooks = require('feathers-hooks-common');
const apiKey = require('./apiKey');
const app = express(feathers());
app.configure(express.rest());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.configure(auth({ secret: 'secret' }));
app.configure(jwt());
app.configure(
apiKey({
header: 'x-api-key',
allowedKeys: ['opensesame']
})
);
app.use('/users', memory());
const authenticate = () =>
commonHooks.iff(
commonHooks.every(commonHooks.isProvider('external')),
commonHooks.iffElse(
ctx => ctx.params.headers['x-api-key'],
auth.hooks.authenticate('apiKey'),
auth.hooks.authenticate(['jwt'])
)
);
app.hooks({
before: {
all: [authenticate()]
}
});
app.listen(8080);
Now any request with a header x-api-key
and the value opensesame
will be authenticated by the server.
Creating an Anonymous User Strategy¶
The second strategy we’ll look at is for an anonymous user. For this
specific flow we’ll expect the client to call the /authentication
endpoint letting us know that it wants to authenticate anonymously. The
server will then create a new user and return a new JWT token that the
client will have to use from that point onwards.
First let’s create the strategy using passport-custom
const Strategy = require('passport-custom');
module.exports = opts => {
return function() {
const verifier = async (req, done) => {
// create a new user in the user service
// mark this user with a specific anonymous=true attribute
const user = await this.service(opts.userService).create({
anonymous: true
});
// authenticate the request with this user
return done(null, user, {
userId: user.id
});
};
// register the strategy in the app.passport instance
this.passport.use('anonymous', new Strategy(verifier));
};
};
Next let’s update our server.js
to use this strategy.
const anonymous = require('./anonymous');
app.configure(
anonymous({
// the user service
userService: 'users'
})
);
const authenticate = () =>
commonHooks.iff(
commonHooks.every(commonHooks.isProvider('external')),
commonHooks.iffElse(
ctx => ctx.params.headers['x-api-key'],
auth.hooks.authenticate('apiKey'),
// add the additional anonymous strategy
auth.hooks.authenticate(['jwt', 'anonymous'])
)
);
Finally our server.js
looks like this:
const feathers = require('@feathersjs/feathers');
const express = require('@feathersjs/express');
const auth = require('@feathersjs/authentication');
const jwt = require('@feathersjs/authentication-jwt');
const memory = require('feathers-memory');
const commonHooks = require('feathers-hooks-common');
const apiKey = require('./apiKey');
const anonymous = require('./anonymous');
const app = express(feathers());
app.configure(express.rest());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.configure(auth({ secret: 'secret' }));
app.configure(jwt());
app.configure(
apiKey({
header: 'x-api-key',
allowedKeys: ['opensesame']
})
);
app.configure(
anonymous({
userService: 'users'
})
);
app.use('/users', memory());
const authenticate = () =>
commonHooks.iff(
commonHooks.every(commonHooks.isProvider('external')),
commonHooks.iffElse(
ctx => ctx.params.headers['x-api-key'],
auth.hooks.authenticate('apiKey'),
auth.hooks.authenticate(['jwt', 'anonymous'])
)
);
app.hooks({
before: {
all: [authenticate()]
}
});
app.listen(8080);
Now any such request will return a valid JWT token:
POST /authentication
{
strategy: 'anonymous'
}
Note that this looks very similar to a request body for local
strategy:
POST /authentication
{
strategy: 'local',
username: 'admin',
password: 'password'
}
So for any new strategy we register, we can call the /authentication
endpoint with a specific body and expect a valid JWT in return, which we
can use from thereon.
As we can see it’s very easy to create a completely custom auth strategy
in a standard passport way using passport-custom
.
Happy Hacking!!

Political parties urged to support UK music industry after General Election
Campaigners have cited Ed Sheeran and Lewis Capaldi in a plea for all political parties to protect the UK’s lucrative music industry
Party leaders contesting the upcoming General Election have been asked to guarantee the future of UK talent whatever the outcome of the vote.
Global stars and staggering revenues have been cited by industry lobbying group UK Music’s chief executive Michael Dugher.
He asked Prime Minister Boris Johnson, Labour leader Jeremy Corbyn, and Liberal Democrat leader Jo Swinson to support the lucrative industry.
In the letter he invoked Sam Fender, Sheeran and Capaldi as examples of the UK’s musical success, which requires copyright protection, infrastructure, and education to continue.
He wrote: “Year after year, decade after decade, this country produces incredibly creative musical talent that consistently takes the world by storm.
“People around the world still look in awe at British musicians
“Year after year, decade after decade, this country produces incredibly creative musical talent that consistently takes the world by storm.
“People around the world still look in awe at British musicians.”
Mr Dugher added: “The UK music industry supports well over hundreds of thousands of jobs and contributes a massive amount to both the British economy and our cultural life.
“This General Election could be game-changing for all sorts of reasons and I’m determined to make sure that the voice of our vibrant and diverse music industry is heard loud and clear, whoever ends up in Downing Street.”
UK Music has outlined a number of areas of concern for which is has sought support and assurance from political leaders.
These include protecting copyright for UK creators, despite exiting EU legislative arrangements.
The group has also called for better music education for young people, amid declining numbers of students taking the subject, particularly those from less privileged backgrounds.
The letter also calls for the infrastructure and venues to keep talent continually emerging.
Mr Dugher added: “At this critical time as our country prepares to head to the polls on December 12 and elect a new Parliament to tackle the challenges we face, UK Music seeks the support of all political parties, and the candidates representing them, for a vision of the music industry that will tackle fundamental issues, enable even greater future success to continue and promote growth.”
UK Music will release a report into the health of the industry on November 20.

Part 4: Twisted Plugin
Creating our twistd
command line plugin for easy deployment.
Module Setup
To setup our plugin, we need a way to parse our settings configuration. For this, we use ConfigParser
from Python’s standard library:
1 2 3 | from ConfigParser import ConfigParser
# <--snip-->
|
Next, we have a bunch of Twisted import statements to create our plugin (don’t get scared!):
1 2 3 4 5 6 7 8 9 | # <--snip-->
from twisted.application.service import IServiceMaker, Service
from twisted.internet.endpoints import clientFromString
from twisted.plugin import IPlugin
from twisted.python import usage, log
from zope.interface import implementer
# <--snip-->
|
And last, we’ll import our talkback bot and quote picker function:
1 2 3 4 5 6 | # <--snip-->
from talkback.bot import TalkBackBotFactory
from talkback.quote_picker import QuotePicker
# <--snip-->
|
Again, notice the order of imports per Python’s style guide grouped by standard library, third-party libraries/modules, and our own written modules, each group of import statements in alphabetical order.
Scaffolding for talkbackbot_plugin.py
We’ll first want to leverage Twisted’s usage
module to parse our configuration:
1 2 3 4 5 | # <--snip-->
class Options(usage.Options):
# <--snip-->
|
Next, the actual class that constructs our application using Twisted’s Service
class to start and stop our application:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | # <--snip-->
class TalkBackBotService(Service):
def __init__(self, endpoint, channel, nickname, realname, quotesFilename,
triggers):
def startService(self):
"""Construct a client & connect to server."""
def stopService(self):
"""Disconnect."""
# <--snip-->
|
To go along with our TalkBackBotService
, we create a Maker class (similar to having our bot Factory class to create our bot) that constructs our service.
1 2 3 4 5 6 7 8 9 10 11 | # <--snip-->
class BotServiceMaker(object):
tapname = "twsrs"
description = "IRC bot that provides quotations from notable women"
options = Options
def makeService(self, options):
"""Construct the talkbackbot service."""
# <--snip-->
|
Lastly, we construct an object which calls our BotServiceMaker
:
1 2 3 | # <--snip-->
serviceMaker = BotServiceMaker()
|
Let’s first approach our BotServiceMaker
.
BotServiceMaker class
First, a few settings for our class:
1 2 3 4 5 6 7 | # <--snip-->
tapname = "twsrs"
description = "IRC bot that provides quotations from notable women"
options = Options
# <--snip-->
|
The tapname
is the short string name for our plugin; this is the subcommand of twistd
. The description
is the short summary of what the plugin does. And the options
variable refers to our Options
class that we will code out in a bit.
Next, our makeService
function:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | # <--snip-->
def makeService(self, options):
"""Construct the talkbackbot service."""
config = ConfigParser()
config.read([options['config']])
triggers = [
trigger.strip()
for trigger
in config.get('talkback', 'triggers').split('\n')
if trigger.strip()
]
return TalkBackBotService(
endpoint=config.get('irc', 'endpoint'),
channel=config.get('irc', 'channel'),
nickname=config.get('irc', 'nickname'),
realname=config.get('irc', 'realname'),
quotesFilename=config.get('talkback', 'quotesFilename'),
triggers=triggers,
)
# <--snip-->
|
First, we instantiate ConfigParser()
, and read from our options
parameter that we pass in to grab 'config'
in our options. This is essentially grabbing and reading our settings.ini
file. Next, we create a list comprehension for triggers
. We strip the null characters for every trigger we find in our settings.ini file. Looking at the file, we are able to pull out only the triggers with the config.get('talkback', 'triggers')
function:
# <--snip-->
[talkback]
# <--snip-->
triggers =
that's what she said
The .split('\n')
means that each quote is separated by a new line.
After we setup our triggers, we then return our instantiated TalkBackBotService
class with the parameters grabbed from our config
variable:
1 2 3 4 5 6 7 8 9 10 | # <--snip-->
return TalkBackBotService(
endpoint=config.get('irc', 'endpoint'),
channel=config.get('irc', 'channel'),
nickname=config.get('irc', 'nickname'),
realname=config.get('irc', 'realname'),
quotesFilename=config.get('talkback', 'quotesFilename'),
triggers=triggers,
)
|
One final bit that I didn’t detail in the scaffolding: Twisted makes use of Zope’s interfaces. Earlier, we imported implementer
from zope.interface
. The way we will use implementer
is a Python decorator, and with Twisted, it is considered an interface:
1 2 3 4 5 6 | # <--snip-->
@implementer(IServiceMaker, IPlugin)
class BotServiceMaker(object):
# <--snip-->
|
Rather than having BotServiceMaker
inherit from both IServiceMaker
and IPlugin
, we use @implementer
as a marker saying “this class implements these interfaces”. You can read more about Twisted’s interfaces here.
Options class
This is pretty simple: we need to tell our Twisted application about the options it can handle:
1 2 3 4 5 6 7 8 | # <--snip-->
class Options(usage.Options):
optParameters = [
['config', 'c', 'settings.ini', 'Configuration file.'],
]
# <--snip-->
|
This gives us two flags: --config
and -c
that we could include when we run twistd twsrs
(remember that twsrs
is the tapname
for our service):
1 2 | $ twistd twsrs --config=/path/to/settings.ini
$ twistd twsrs -c /path/to/settings.ini
|
We also feed it a default value, in this case, settings.ini
. If you were not to include a config flag, the application would look for settings.ini
in the current directory (same directory that the README.md
, settings.ini.EXAMPLE
, quotes.txt
files live).
TalkBackBotService class
Our BotServiceMaker.makeService
method returns an instance of TalkBackBotService
with parameters grabbed from our configuration, definied in settings.ini
. Now let’s implement our TalkBackBotService
class.
We’ll first create a private variable _bot
with value None
(private is denoted with a leading _
, and while it’s not meant to be publically accessible, it isn’t enforced).
We also initialize the class:
1 2 3 4 5 6 7 8 9 10 11 12 | # <--snip-->
def __init__(self, endpoint, channel, nickname, realname, quotesFilename,
triggers):
self._endpoint = endpoint
self._channel = channel
self._nickname = nickname
self._realname = realname
self._quotesFilename = quotesFilename
self._triggers = triggers
# <--snip-->
|
This __init__
function gets called when we return TalkBackBotService
from BotServiceMaker.makeService
method with our settings from our parsed configuration.
Next, we’ll define startService
method, which is a part of the Service
base class we inherit from:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | # <--snip-->
def startService(self):
"""Construct a client & connect to server."""
from twisted.internet import reactor
def connected(bot):
self._bot = bot
def failure(err):
log.err(err, _why='Could not connect to specified server.')
reactor.stop()
quotes = QuotePicker(self._quotesFilename)
client = clientFromString(reactor, self._endpoint)
factory = TalkBackBotFactory(
self._channel,
self._nickname,
self._realname,
quotes,
self._triggers,
)
return client.connect(factory).addCallbacks(connected, failure)
# <--snip-->
|
Our startService
method has a few interesting things going on. We first have an import statement nested in it: from twisted.internet import reactor
. Ashwini Oruganti, a contributor to Twisted, wrote up a great blog post detailing why we nest this import statement within startService
method:
If you import
twisted.internet.reactor
without first installing a specific reactor implementation, then Twisted will install the default reactor for you. The particular one you get will depend on the operating system and Twisted version you are using. For that reason, it is general practice not to import the reactor at the top level of modules to avoid accidentally installing the default reactor. Instead, import the reactor in the same scope in which you use it.
Within startService
method, we define connected(bot)
, which assigns our private variable we defined earlier, _bot
, to the passed-in parameter, bot
.
We also define failure(err)
within startService
to log that we could not connect to a specific service, along with the error message the failure gave us. We then stop our reactor upon calling failure
.
Next, we instantiate the QuotePicker
class with our quote file with defining quotes
. This pulls in all our quotes within quotes.txt
file.
Now we need to define a client
that basically constructs an endpoint based on a string with clientFromString
function. The clientFromString
takes in the reactor
that we imported, and the endpoint, which is grabbed from the endpoint string defined in our settings.ini
file. The reactor
Twisted’s event loop driving your Twisted applications. More about Twisted’s reactor
object is detailed in its howto documentation.
We then create a factory
variable that instantiates TalkBackBotFactory
defined in bot.py
which passes in the appropriate parameters.
Last, we return client
, defined by our endpoint, and connect to our endpoint with the factory
variable. We also add addCallbacks
which take a pair of functions of what happens on success and on failure (our connected
and failure
functions).
The last function we define in our TalkBackBotService
class is stopService
:
1 2 3 4 5 6 7 8 | # <--snip-->
def stopService(self):
"""Disconnect."""
if self._bot and self._bot.transport.connected:
self._bot.transport.loseConnection()
# <--snip-->
|
It is a deferred (a callback which we put off until later) that is triggered when the service closes our connection between the client and server (if _bot
is not None
, and if the bot is connected).
Near the home stretch!
Constructing BotServiceMaker
At the very end of our plugin module, we have to include: serviceMaker = BotServiceMaker()
to construct an object which provides the relevant interfaces to bind to IPlugin
and IServiceMaker
.
