MQTTSSLSecurityPolicy
evaluates server trust against pinned X.509 certificates and public keys over secure connections.If your app using security model which require pinning SSL certificates to helps prevent man-in-the-middle attacks and other vulnerabilities. you need to set securityPolicy to properly value(see MQTTSSLSecurityPolicy.h for more detail).
NOTE: about self-signed server certificates: if your server using Self-signed certificates to establish SSL/TLS connection, you need to set property: MQTTSSLSecurityPolicy.allowInvalidCertificates=YES.
If SSL is enabled, by default it only evaluate server’s certificates using CA infrastructure, and for most case, this type of check is enough. However, if your app using security model which require pinning SSL certificates to helps prevent man-in-the-middle attacks and other vulnerabilities. you may need to set securityPolicy to properly value(see MQTTSSLSecurityPolicy.h for more detail).
NOTE: about self-signed server certificates: In CA infrastructure, you may establish a SSL/TLS connection with server which using self-signed certificates by install the certificates into OS keychain(either programmatically or manually). however, this method has some disadvantages:
- every socket you app created will trust certificates you added.
- if user choice to remove certificates from keychain, you app need to handling certificates re-adding.
If you only want to verify the cert for the socket you are creating and for no other sockets in your app, you need to use MQTTSSLSecurityPolicy. And if you use self-signed server certificates, your need to set property: MQTTSSLSecurityPolicy.allowInvalidCertificates=YES
Adding pinned SSL certificates to your app helps prevent man-in-the-middle attacks and other vulnerabilities. Applications dealing with sensitive customer data or financial information are strongly encouraged to route all communication over an SSL/TLS connection with SSL pinning configured and enabled.

CoChannel
public final class CoChannel<Element>
extension CoChannel: CoCancellable
Channel is a non-blocking primitive for communication between a sender and a receiver. Conceptually, a channel is similar to a queue that allows to suspend a coroutine on receive if it is empty or on send if it is full.

- Access to DB4SCI requires user authentication. Active Directory is used to provide authentication.
- NginX handles http and TSL transports and sends data via WSGI to Flask on port 5000
- uWSGI is used as a wrapper for DB4SCI Flask application.
- State data for the application is stored in a PostgreSQL database named mydb_admin. SQLAlchemy for Flask is the API to PostgreSQL for the administrative database. Metadata about each database request is kept in the admin database. Information about the requester, backup policy and container information are kept.
- There is enough metadata in the admin database to recreate the Docker container. The admin database knows the location and timestamps for the database backups.
- Each database created by DB4SCI gives the requester full administrative privileges. Each database has its own unique storage and network port.


Lack of Diversity in the Tech Industry and What To Do About It
October 29, 2014
One of the largest issues facing the tech industry these days seems to be a lack of diversity both in terms of ethnicity and gender. While these are hardly new problems for the tech industry it does seem that they are starting to get some publicity and that the industry has begun to recognize that there is a problem and something needs to be done about it.
What is the problem?
Both women and minorities (especially blacks and hispanics) are severely underrepresented in the tech industry, especially so in technical and leadership roles. There are myriad statistics to back this up readily available with a quick google search so I'll be brief and just say that from most of my reading the percentage of tech employees that are women is around 25% and under 5% for both blacks and hispanics.
Why is this a problem?
To start with, a more diverse workforce would equip the industry with more diverse perspectives, experiences, etc. and would thus help the industry produce better products that speak to a larger range of the population. Furthermore, after reading more about this issue it became clear that a large reason this lack of diversity exists is due to a hostile culture (especially towards women). This is a problem because, well, hostile cultures are bad.
So what can we do to remedy this problem? One idea is to increase the number of women and minorities that study STEM fields in school. Some strategies to do this would be to increase the number of female and minority mentors to these students and to increase the number of scholarships available to these students (maybe tech companies could sponsor these scholarships, as well). Programming bootcamps, such as Dev Bootcamp (shameless plug) are also working to fill this gap by working with programs like Lenovo scholars.
Another solution that I would recommend is trying to enact a cultural shift. Leaders in the tech industry must recognize their power and responsibility and make it a priority to show everyone that diversity is good for the industry and that the sometimes pervasive macho attitudes are not cool or acceptible. This will take time and will not be easy but, like I think would eventually win out over the current culture.

MetaGraph
Project represents automatic metagraph visualization based on the principles of force-directed algorithms.
Also you can create your own metagraph with this tool.
Definition . Metagraph is a construct S = <V, M, E>, where
V - set of metagraph vertices,
M - set of metavertices,
E - set of edges.
Metavertex is a vertex that includes some other vertices that called inner vertices for this metavertex.
Metagraph node is a vertex or a metavertex.
Metagraph edge is oriented pair of vertices e(mv_out ,mv_in), where mv_out - tail, mv_in - head.

Contributing to the QATrack+ Development¶
We would certainly welcome contributions of code or cleanups/refactorings of existing code from anyone who is interested in helping out.
This page will get filled out with more details as time goes on, but if you’re interested in hacking on the QATrack+ code please fork the QATrack+ repository on bitbucket.
Please feel free to edit this page and add any details you think will be helpful to other people!
Getting ahold of the source code¶
The general sequence to contribute/patch source code to QATrack+ is as follows:
- Install git
- Create a Bitbucket account
- Fork the QATrack+ respository found here
- Clone your newly forked repository to your local computer.
- Add a new feature, clean up some code, add tests etc
- Push your changes back to your repository
- Create a pull request for the main TOHCC repository
Installing git¶
QATrack+ uses git for revision control purposes. If you’re new to git, Bitbucket has a tutorials for installing/configuring git on Windows, and Mac OSX (ignore the Mercurial/HG sections)...if you’re on a Linux system, git should be available via your package manager (e.g. apt-get install git, yum install git-core etc.).

A decorator that transforms a class property to a component internal property.
An internal property is a property that works under the hood. Its role is to be an intrinsic mechanism, so it would be better to avoid sharing and reusing it outside of the class.
For React users, this concept may be familiar as a Component State.
@element('my-component-with-modal', {renderer})
class MyComponentWithModal extends HTMLElement {
@internal private isOpen: boolean = false;
private handleOpen(): void {
this.isOpen = !this.isOpen;
}
private [render](): TemplateResult {
return html`
<button @click=${this.handleOpen}>Open modal</button>
<some-modal ?open=${this.isOpen}></some-modal>
`;
}
}
A symbolic name of the ElementGears.internalChangedCallback. Use it to declare the method.
class Foo extends HTMLElement {
[internalChangedCallback](propertyName: PropertyKey, oldValue: unknown, newValue: unknown): void {
// method body
}
}
A symbolic name of the ElementGears.propertyChangedCallback. Use it to declare the method.
class Foo extends HTMLElement {
[propertyChangedCallback](propertyName: PropertyKey, oldValue: unknown, newValue: unknown): void {
// method body
}
}
A symbolic name of the ElementGears.render. Use it to declare the method.
class Foo extends HTMLElement {
[render](): unknown {
// method body
}
}
A symbolic name of the ElementGears.updatedCallback. Use it to declare the method.
class Foo extends HTMLElement {
[updatedCallback](): void {
// method body
}
}
A decorator that binds a class property to an appropriate attribute and provides a transformation to the property value to and from the attribute string.
An attribute is the most well-known property type and also the most complex
type to work with. Standard requires that it should only be a string type,
but Corpuscule allows it to have three primitive types: String
, Boolean
,
and Number
.
connectedCallback
is
allowed yet also limited, because component users can set these attributes
before connection to DOM and would be upset if default values override ones
made by them. If you consider all these possibilities, you can set defaults
in connectedCallback
manually; it will require additional render for your
component though.HTMLElement
attributes storage, and
whenever you request them, cast to proper type happens. That's the reason
you cannot save in attribute more than just a primitive type.attributeChangedCallback
method with
attribute name, old and new value.
<my-button disabled>Don't click me</my-button>
a name of the attribute to bind.
a type of the property value that should be converted.
A decorator that transforms a class getter to a computed property. It is an approach that can be used to reduce the number of expensive calculations by remembering the latest result produced by the getter and providing it until all the class properties the getter depends on are changed.
a token produced by a createComputingToken to bind this decorator with @observer.
A decorator that converts a class declaration to a Custom Element and unites all other decorators making a complete working system from them.
a name of the new Custom Element. According to the standard, it should contain a dash symbol.
a list of options that tunes the custom element according to the requirements.
A decorator that makes a class property observed. It works together with the computed property created via @computer decorator to reset the remembered getter result. When a value of one of the observed properties is changed, the remembered result of the computed one is reset, and the next call to the getter will start the recalculation which result will be remembered again.
Each computed property will observe all the observed properties at once and will drop the remembered result on any of their change.
a token produced by a createComputingToken to bind this decorator with @computer.
A decorator that converts a class property to a component regular property.
A regular property of the component is a property that can be set only imperatively by assigning the component instance filed.
@element('my-square-info', {renderer})
class MySquareInfo extends HTMLElement {
@property(v => typeof v === 'object' && v.width && v.height)
public square = {width: 10, height: 10};
protected [render](): TemplateResult {
return html`

Square width: ${this.square.width}

Square height: ${this.square.height}

`;
}
}
customElements.whenDefined('my-component').then(() => {
const mySquareInfo = document.createElement('my-square-info');
mySquareInfo.square = {width: 40, height: 40};
document.body.append(mySquareInfo);
});
a function that checks the type of the assigned value; if it
returns false
, the error will be thrown.
A decorator that converts a property to a getter that finds an element with
the selector
in the Light or Shadow DOM of your element using the
querySelector
method.
@element('my-element', {renderer})
class MyElement extends HTMLElement {
@query('#target') private target: HTMLSpanElement;
protected [render](): TemplateResult {
return html`

`;
}
}
a selector of the desired element.
a set of decorator options
A decorator that converts a property to a getter that finds all elements
with the selector
in the Light or Shadow DOM of your element using the
querySelectorAll
method.
@element('my-element', {renderer})
class MyElement extends HTMLElement {
@queryAll('.target') private targets: HTMLCollectionOf<HTMLSpanElement>;
protected [render](): TemplateResult {
return html`

`;
}
}
a selector of the desired set of elements.

Generated using TypeDoc
This module provides tools to define web components in a declarative way.
How it works
By default, web components are too low-level to define them directly. They require too much boilerplate to create and support. This module provides special decorators that allow setting main parts of web components in the most declarative way possible. These decorators combined, create a component system that works together and is easy to interact with.
There are the following decorators that makes the system work:
Element Lifecycle
Each custom element marked with an @element decorator has the following lifecycle (including standard JS class and custom element lifecycle).
A rendering system is able to wait until multiple properties are set synchronously; only then the single rendering will be performed. However, be careful with the asynchronous setting: it may cause re-rendering on each assignment.
document.createElement
method, this hook is separate.connectedCallback
is fired. Can be invoked multiple times for the single element.disconnectedCallback
will be invoked directly. Can be invoked multiple times for the single element.

Giving it a try at the command line
The cmdline_audio_peer application can be tested locally using your own server and it can be tested using our server as well. NOTE: Our server is a best-efforts up-time server. So, our IP and port will be given here, but if it doesn't work, run it locally and see whether the problem lies with the build locally or with our server.
Setting up the server locally
Trying locally:
Launch your local server:
(Linux): ./third_party/webrtc/trunk/out/Release/peerconnection_server
(Mac): ./third_party/webrtc/trunk/xcodebuild/Release/peerconnection_server
This should elicit 'Server listening on port 8888'
Running the client
Note that this part could be skipped altogether if you simply wish to use the plugin and avoid the use of the command line altogether.
Using the client:
(Linux): ./third_party/webrtc/trunk/out/Release/cmdline_audio_peer --server=localhost:8888 --peername=use-your-own-name
(Mac): ./third_party/webrtc/trunk/xcodebuild/Release/cmdline_audio_peer --server=localhost:8888 --peername=use-your-own-name
If you wish to attempt to connect to our server, you may simply use "--server=<IP_ADDRESS>:8888" instead of the localhost. Please note --help can be used to get a full list of options for the command line.
Once the client is running, issue the command "signin" and you should see the output of:
Signing in...
Server: localhost
Port: 8888
Client: Sign in complete
If this occurs, you're in great shape. Once a second person runs the same command line (with a different peer name), you may issue a "call peer-name-to-call". This will create a connection for audio over the internet with that peer.
Note that calling is not limited to 2-way. You may issue additional "call next-name" many times to create multi-party calls. However, there is a non-intuitive notion behind 'call'. Call is creating a peer connection directly to the person you ask it to call. When it is a 2-way call, this is perfect. When a 3-way call happens, there's a need for an extra 'link' or 'call' to be created. And with 4-way calls, there are more yet again. As an example, consider we have peers named A, B, C, and D.
A calls B. No problem. 2-way call.
Now, with A+B in a call, A issues a call to C. At this point, A has a 3-way link with B and C.
HOWEVER, B does not have a link to C and therefore, there is a need for B to call C or for C to call B. This would establish the desired 3-way link.
With a 3-way call in progress, if we wish to fully add D into the conversation, each peer (A, B, C) would have to call D in order to have a full link-up -- or D would have to call A, B, and C -- either way. In each case, the peer connections must be setup individually.
Conversely, the 'hangup' command is similar. If you have a 4-way call going, and you're 'A', you may wish to hang up in which case you need to 'hangup D', 'hangup C', and 'hangup B'. This would fully hangup as it destroys each peer connection individually. The nice effect here is that in the 4-way call, it is possible to simply drop one individual by hanging up on them alone.
While this is a bit confusing and may be non-intuitive, it was left this way to allow people to play with the notions of individual connections via 'call' and 'hangup'.
Running the Plug-in
The 'installation' of the plugin is quite simple. Once it is installed, make sure you've restarted your browser (so it picks up the new plugin) and load/open 'GoCast.html' file from src/GoCast.html. Please NOTE: The plugin will crash if loaded twice within a single browser instance.
Another option for trying out your plugin and server is to use the web page at Voice Chat.
Mac installation
Plug-ins must be installed in ~/Library/Internet Plug-Ins
If you're a developer, the best way to handle this is with a symbolic link back to where your favorite build-output is located. For example, if you intend to use the debug version of the plugin and want to avoid copying it at the end of each build:
cd ~/Library/Internet Plug-Ins
ln -s ~/<your-dev-location>/webrtc_plugin/third_party/src/js_api/build/projects/WebrtcPlugin/Debug/WebrtcPlugin.plugin
If you're wanting to simply use the resultant build, you may wish to use Finder to copy ~/<your-dev-location>/webrtc_plugin/third_party/src/js_api/build/projects/WebrtcPlugin/Release/WebrtcPlugin.plugin into ~/Library/Internet Plug-Ins Note: Finder many times will not show ~/Library in an effort to protect the innocent. Simply use the menu 'Go->Goto Folder...' to get to ~/Library/Internet Plug-Ins or copy the plugin recursively from the command line.

3.2. Shear Building: HAZUS Assessment¶
This study explores a simple uncertainty propagation problem in the following three story shear building and employs the HAZUS methodology for assessing damage and loss:
This example uses the PBE application to automatically prepare an column model that represents the three-story structure, subject it to a suite of ground motion time histories, and evaluate the seismic performance of the building using the Hazus Earthquake methodology.
Each step of the workflow for this problem is explained below by sequentially walking through the input panels and highlighting their role in the simulation. The file input.json
contains all of the settings for this exercise. It can be opened (using File/Open) to automatically populate the fields in the user interface.
3.2.1. Step 1: UQ¶
This panel provides an interface to various forward propagation procedures which are used to sample the random variables defined in later panels and propagate each realization through the workflow. This process can be used to characterize the uncertainty in the workflow outputs. For this example, a latin hypercube sampling procedure (LHS) is used with 40
samples and a seed of 775
. Fixing the seed ensures the same random sample every time the calculation is run.
3.2.2. Step 2: GI¶
Next, the GI panel may be used to define metadata and other general information about the model. Some of the values are automatically updated by later panels while others are only providing information about the model and not used for the simulation.
It is important to review and specify the desired Units for the calculation here. It is important to provide all inputs assuming these units when no other instructions are given by the following panels. The length unit is used to define velocity and acceleration units as well.
3.2.3. Step 3: SIM¶
The SIM panel can be used to define the simulation model. In this example we leverage the convenient MDOF tool which provides a high-level interface for defining simple parameterized structural analysis models. Either variable names, or literal values can be entered in the fields of this panel, as shown in the following figure.
This model could have random properties that we could sample and propagate the corresponding uncertainty through the workflow. If a variable name is entered, PBE automatically identifies it as a random variable, and creates a corresponding entry in the RV panel. Several examples in the documentation of the EE-UQ application demonstrate this feature on models of various complexity. In this example, we use a deterministic structural model for the sake of simplicity.
3.2.4. Step 4: EVT¶
The EVT panel provides various Load Generator options that can either import ground motion loads from external files or connect to the PEER NGA database and obtain loads that represent a target spectrum or generate loads during the simulation using a stochastic process. We will use the latter solution in this example by selecting the Stochastic Ground Motion option.
The Vlachos et al. (2018) model generates ground motion time histories based on three parameters: magnitude, distance, and shear-wave velocity in the top 30 meters of the soil. We specify a magnitude 7
earthquake 40
kms from the site of interest. As for the shear-wave velocity, we introduce a random variable by providing vs
as input. This is recognized by PBE and the corresponding variable is automatically added to the RV panel.
3.2.5. Step 5: FEM¶
We now proceed to the FEM panel where we can adjust settings for running the dynamic analysis. The default settings are typically appropriate for analyses that use the MDOF tool.
3.2.6. Step 6: RV¶
Now in the RV panel we will enter the distributions and values for our random variables. Because of the steps we have followed and entries we have made, when this tab is opened it already contains the vs
random variable. We choose to model the uncertainty in the shear wave velocity using a normal distribution with a mean of 400 m/s and a standard deviation of 100 m/s.
Warning
Do not leave any of the distributions for these values as constant when using the Dakota UQ engine.
3.2.7. Step 7: DL¶
The last step in the setup is the DL panel. We use the four tabs in this panel to specify the performance model following the Hazus Earthquake methodology.
First, in the Asset tab, we choose the Hazus Earthquake
component vulnerability database that is bundled with the PBE application. This loads all of the building archetypes handled by Hazus in the Available in DB
list. We assign the STR.S1M.MC
steel frame archetype as the structural component. NSD
and NSA.MC
components are added to represent drift and acceleration-sensitive non-structural components.
Because Hazus components are assigned at the building level, there is only one performance group created for each. The acceleration-sensitive component is assigned to the roof of the building (to obtain roof acceleration from there) while the drift-sensitive components are assigned to the first floor. This latter assignment is used with roof drift EDPs in buildings regardless of the number of floors they have.
Under the Demands tab, we specify that the demand data is provided by the Workflow automatically; we assume that demands follow a multivariate lognormal distribution. After fitting such a distribution to the data, we sample 500 demand realizations for damage and loss assessment.
The Damage tab setup is simple when the Hazus earthquake methodology is used because this method includes collapse in the structure component damage states and does not consider irreparable damage. The Damage Process employed by this method is included in PBE and selected for this example.
Losses are calculated using the included Hazus Earthquake consequence functions for repair costs and an Automatic mapping between damaged components and consequence models. This mapping uses the occupancy type and component types specified in the Asset tab earlier and selects the corresponding consequence functions following the Hazus methodology.
3.2.8. Analysis & Results¶
Once a full workflow has been defined click on the Run button. When the analysis is complete the RES tab will be activated and the results will be displayed. When a HAZUS assessment has been conducted, the results panel will resemble the following figures which show the Summary and Data tabs, respectively.
In the Data tab of the RES panel, we are presented with both a graphical plot and a tabular listing of the data. By left- and right-clicking on the individual columns the plot axis changes (left mouse click controls vertical axis, right mouse click the horizontal axis). If a singular column of the tabular data is selected with both right and left mouse buttons, a frequency and CDF plot will be displayed.

--- layout: post authors: ["Greg Wilson"] title: "Why It Matters" date: 2014-11-11 time: "07:0:00" tags: ["Opinion"] ---
Sometimes I forget that it isn't obvious why scientists ought to learn to program—or why anyone else ought to. Being more productive, getting a better job... Those are all good reasons, but as Bret Victor points out, if we focus on those, we risk losing sight of what matters most.
To explain that, I have to quote Matthew Crawford's thought-provoking (and sometimes infuriating) Shop Class as Soulcraft:
We in the West have arranged our institutions to prevent the concentration of political power... But we have failed utterly to prevent the concentration of economic power, or take account of how such concentration damages the conditions under which full human flourishing becomes possible... Too often, the defenders of free markets forget that what we really want is free men.
Crawford believes that removing the experience of working with things from everyday life hasn't just deskilled us; it has demoralized us. Modern knowledge workers are just as alienated from their labor as any other assembly line worker; the gradual substitution of process for judgment is only "progress" if pride in one's work and connection with one's peers is left out of the equation.
That, for me, is what we're really fighting for. Making "hands-on" part of everyday life once again will, I hope, help children and grownups alike learn perseverance, curiosity, conscientiousness, optimism, and self-control. It's also my answer to people who ask why we don't just give scientists tools that will do what they need, and leave the programming to the programmers.
  My daughter had that same smile last Saturday on her way home from a Girls Learning Code workshop on creating web pages. She's never going to be that proud of "personalizing" her home page using one of a dozen canned themes that someone else put together. She's never going to get up at six o'clock on a Sunday morning to create more stuff if all we give her is pull-down menus, just as scientists are never going to create things that we could never think of if we don't show them how.
And you see the title over the box, on the right? It says "Universal Building Sets". That's what we're teaching—that, and the freedom they bring.

A LITTLE while, a little while,
The weary task is put away,
And I can sing and I can smile,
Alike, while I have holiday.
Where wilt thou go, my harassed heart—
What thought, what scene invites thee now
What spot, or near or far apart,
Has rest for thee, my weary brow?
There is a spot, ’mid barren hills,
Where winter howls, and driving rain;
But, if the dreary tempest chills,
There is a light that warms again.
The house is old, the trees are bare,
Moonless above bends twilight’s dome;
But what on earth is half so dear—
So longed for—as the hearth of home?
The mute bird sitting on the stone,
The dank moss dripping from the wall,
The thorn-trees gaunt, the walks o’ergrown,
I love them—how I love them all!
Still, as I mused, the naked room,
The alien firelight died away;
And from the midst of cheerless gloom,
I passed to bright, unclouded day.
A little and a lone green lane
That opened on a common wide;
A distant, dreamy, dim blue chain
Of mountains circling every side.

THAT was the scene, I knew it well;
I knew the turfy pathway’s sweep,
That, winding o’er each billowy swell,
Marked out the tracks of wandering sheep.
Could I have lingered but an hour,
It well had paid a week of toil;
But Truth has banished Fancy’s power:
Restraint and heavy task recoil.
Even as I stood with raptured eye,
Absorbed in bliss so deep and dear,
My hour of rest had fleeted by,
And back came labour, bondage, care.

Tom Dixon Wants People to Remember the Joy of Using Their Senses
The designer speaks about his TOUCHYSMELLYFEELYNOISYTASTY activation.
by Nia GroceTom Dixon’s multi-sensory TOUCHYSMELLYFEELYNOISYTASTY activation was a must-see at the London Design Festival this September, transforming the interior designer’s entire Coal Office complex into an installation filled with “the flavors, the fragrances, the sounds, the colors and the textures of the future.” Stemming from its success in the U.K., the unique idea made its mark in New York this week at Dixon’s namesake retail store, bringing a host of new collaborators onboard for the sensational experience.
For this edition of the campaign, Dixon recruited local brands and international labels alike that he felt brought a “degree of innovation” to their respective fields. Harry’s razors added to the tactile aspect with complimentary grooming services, while textiles from Bute Fabrics enhanced the handfeel of Tom Dixon’s incoming “Fat” chairs and “Fat” sofa for 2020. The brand’s new fragrance, Underground and Alchemy, permeated the space as a part of the “Smelly” concept, and Cocoon Tea joined several others in the “Tasty” brigade with 100% organic tea.
Swedish synthesizer company Teenage Engineering stepped in for “Noisy,” resulting in an overhanging “chandelier speaker sculpture” (co-designed with Tom Dixon) that features LED lighting which operates in tandem with the music. All the while, guests were immersed in the fine home decor of Dixon’s distinctive Fat, Swirl, Spring and Opal collections.
HYPEBEAST caught up with Dixon during the showcase to learn more about TOUCHYSMELLYFEELYNOISYTASTY, how he chooses his collaborators and what he hopes people can take from the activation.
What was it like designing a multi-sensory experience to showcase your physical product designs? Were there any unexpected challenges?
I think for me, it’s such a broad subject when you start digging into it. The challenge was just really trying to explain it with any degree of clarity when you’ve got all these different partners. But ultimately, there’s joy in it when you’re getting out of your own standard world. I think we spend too much time in interior design and product design, talking to people that all study interior design and product design. So the joy of it is extending your network and diving into other people’s universe. Of course there were challenges but all in all it was refreshing.
Were there any key differences between this edition of the activation and the one you held during London Design Festival?
Yea, totally. They’re completely different partners. In London we have a fully-functioning restaurant, so doing Tasty was a lot easier than it is here, where we only have [options like] tea and small snacks. And we’ve also got maybe three or four times the space and ten times the number of employees there, so the scale is different but the intent is the same.
This activation centers around a lot of collaborative projects. What qualities do you typically look for in collaborators, especially those outside of your usual industry?
It’s exactly the same whether it’s food or it’s music. The quality of the ingredients is really important to us. A degree of innovation in that field and I think something different from everybody else. And just an expertise in what they do which they’re really proud of and able to broadcast. Like the people that make the synthesizer, a Swedish brand, they had a very different angle than any other musical instrument makers. Same with the people here making the tea. Even Harry’s, the razor bar that we’ve got here, it’s rapidly become one of the biggest shaving companies in the world, going from being almost pure digital to having a physical space here. So it’s all kind of with people that try to do things differently.
A lot of your collaborators come from various international regions. Was that conscious to bring in different regions or was it more about the work at the end of the day?
In the end you’re faced partially with the realities of finding people prepared to work on your time scale and have got the means to jump on a project at short notice. But that means that the excitement is you’re meeting a lot of new people the whole time.
What do you hope visitors can take from the activation?
I think my kind of logic here is that people are increasingly kind of two-dimensional and you know they’re wearing their eyes out as well with all this visual stimuli. I’m a designer, I use my eyes mainly but ultimately when I start thinking about interior design, I start thinking a lot about what a place sounds like. Can I hear the music or my partner speaking across the table? Or I start thinking about the smell of a place. Is it smelling like bleach from the cleaning the night before or is it smelling delicious? Then, I’m interested in the tactility of things as well.
I think the message here is like, yes your phone is amazing, yes you can obviously play music on it.  And ultimately, you just move more and more into a virtual world and move more and more into a visual feast on Instagram, but boy you’re missing out if you don’t use your other senses.

CTsimulation User Guide
3. Configure the recon pipeline
The input of CTrecon.m is a configure file which set the parameters to define a recon (pipeline) task
which can not only run an image reconstruction job but also do calibrations, kinds of data/image processes
and even to call a simulaton task. User can run the CTrecon(configurefile);
to do a pipeline task defined by the configurefile
.
3.1 Reconstruction configure
As we played in Quick Start,
a recon .xml configure file '..\Data\recon_series1_120KV200mA.xml'
was auto generated by the CTsimulation.m for user to run the CTrecon.m.
As a sample, let's open this file which reads, (folded)
<?xml version="1.0" encoding="utf-8"?>
<configure>
<recon>
<rawdata>..\Data\rawdata_series1_120KV200mA_v1.0.raw</rawdata>
<IOstandard>./IO\standard\</IOstandard>
<system>
<protocol>
<pipe>
</recon>
</configure>
where the <recon>
contains all sets of the recon parameters of a series, multi <recon>
can be employed
as a multi serieses job;
where the <rawdata>
is the rawdata file path and name, multi rawdata files are not acceptable,
and multi shots of data can be put in one rawdata file ;
a tag <offsetdata>
(skipped in this sample) can be employed to employ an dark current correction by a real time offset data;
where the <IOstandard>
is the path of the the path of I/O defination folder,
as we defined in system configure;
where the <system>
contains the necessary informations of a CT system, which reads,
<system>
<detector_corr>./system\mod\detectorframe\detector_sample_unit24.corr</detector_corr>
<focalposition>0 -550 0</focalposition>
<angulationcode>69120</angulationcode>
<angulationzero>0</angulationzero>
<DBBzero>16384</DBBzero>
<collimatorexplain>./system\mod\detectorframe\collimatorexplain_unit24.xml</collimatorexplain>
</system>
where the <detector_corr>
is the detector calibration table,
in this sample the table file is as same as we used in the simulation;
where the <focalposition>
is the focal(s) position;
where the <angulationcode>
is the maxium angulation code of the rotor per rotation;
where the <angulationzero>
is angulation code of the 'zero point' of the rotor,
the 'zero point' is where the focal (in X-ray tube) on the focalposition we defined, normaly it is on top;
where the <DBBzero>
is the zero offset of the rawdata when it was saved in unsigned integer numbers;
where the <collimatorexplain>
is the configure file to explain the collimator in protocols,
kick here for more information how the machine reads protocols;
where the <protocol>
is the defination of the protocol, which reads,
<protocol>
<scan>Axial</scan>
<collimator>16x1.0</collimator>
<bowtie>Body</bowtie>
<focalspot>1</focalspot>
<focalsize>1</focalsize>
<KV>120</KV>
<mA>200</mA>
<mA_air>30</mA_air>
<viewperrot>1440</viewperrot>
<rotationspeed>1</rotationspeed>
<rotationnumber>1</rotationnumber>
<viewnumber>1440</viewnumber>
<integrationtime>694.4444</integrationtime>
<startangle>0</startangle>
<startcouch>0</startcouch>
<shotnumber>1</shotnumber>
<shotcouchstep>8.8</shotcouchstep>
<couchheight>0</couchheight>
<couchspeed>0</couchspeed>
<gantrytilt>0</gantrytilt>
<rawdatastyle>24bit</rawdatastyle>
<series_index>1</series_index>
</protocol>
where the <scan>
is the scanning mode in 'Axial', 'Helical' or 'Static'(topo);
alomost all those sub-tags in protocol are copied from the protocol configure in simulation,
expect,
the <integrationtime>
is the scan integraion time in microsecond, no matter to skip it;
the <gantrytilt>
is the gantry tilt angle in degree (not π), with a defualt value=0 no matter to skip it.
Let's move on the next tag <pipe>
which defined the pipeline of the reconstruction work flow,
<pipe>
<Log2/>
<Air>
<corr>..\Data\air_series1_120KV200mA_v1.0.corr</corr>
</Air>
<Beamharden>
<corr>..\Data\beamharden_series1_120KV200mA_v1.0.corr</corr>
</Beamharden>
<Hounsefield>
<HCscale>1000</HCscale>
</Hounsefield>
<Axialrebin>
<QDO>0</QDO>
</Axialrebin>
<Filter>
<name>hann</name>
<freqscale>1.2</freqscale>
</Filter>
<Backprojection>
<FOV>500</FOV>
</Backprojection>
</pipe>
The pipeline is a workflow of the serial nodes in the computation of the image reconstruction (or other jobs), each of the nodes is a function to do a
unit process of algrithm. You can find the functions in the folder ~\recon\nodes\ in which the functions are normaly named
in reconnode_nodename.m which can be called in a <pipe>
by its name (not case sensitive).
The code file nodesentry.m is the governing function of all the recon nodes,
it will help you to maintain more recon nodes by registering the nodes' name in that function.
In this sample the pipe line includes these nodes, log2, air (correction), beamharden correction, Hounsefield units (HU) correction, axial-rebin, filter (the F in FBP),
back project. Last it will return the data of image. Some parameters of the nodes can be setted in the tags, e.g. the <corr>
is the path
of a calibration table. But in most cases those settings are not necessary, the process will looking for the coupled calibration tables automatically and
other parameters e.g. the FOV or filter name will be written in (or related with) in protocols.
And to set the parameters in nodes configure is a debug function which will overwrite the automatical settings.
3.2 Advanced Reconstruction Pipeline
In this section we will discuss the recon pipeline samples close to the real production with more recon-nodes to the previous simple one.
These sample reocon confgire files can be found in the folder ~\system\mod\recon\.
Let's show this file recon_Axial_sample2.xml first,
just focus on the different parts:
<system>.\system\mod\recon\reconsystem_sample.xml</system>
...
<pipe>
<Log2/>
<Air/>
<Offfocal/>
<Crosstalk/>
<Beamharden/>
<Nonlinear/>
<Hounsefield>
<HCscale>1000</HCscale>
</Hounsefield>
<Sloperebin/>
<Backprojection>
<upsampling>true</upsampling>
<Filter>
<name>hann</name>
<freqscale>1.5</freqscale>
</Filter>
<FOV>250</FOV>
<method>3D</method>
<Gamma>0.6 1.5</Gamma>
<Zupsampling>4</Zupsampling>
</Backprojection>
<Boneharden>
<Filter>
<name>hann</name>
<freqscale>1.2</freqscale>
</Filter>
<subview>2</subview>
<Boneharden>
<Output>
<files>dicomimage</files>
</Output>
</pipe>
First the <system>
is replaced by a file path which is asigned to the file
reconsystem_sample.xml, mostly those 'redirections' are permitted.
We will discuss the details of this file later, let's move on the <pipe>
(pipeline) secondly.
The pipeline in this sample contians more nodes than the previous simple one. In the correction part there are 3 new nodes,
the <Offfocal>
, the <Crosstalk>
and the <Nonlinear>
(somehow the bad channel correction seems being ignored). Including those more correction nodes it is very closing to a real emplimentation.
Each of the nodes corresponding to a background node-function, you can find them in the folder ~\recon\nodes\
also. If necesssary you can add more nodes funcion here and put them in nodesentry.m
as we mentioned.
There is a difference in <Air>
and <Beamharden>
of this sample with the previous simple sample,
that they didn't asign the calibration tables. Normally, we don't asign the tables but let the program looking for the coupled
calibration tables automatically by a designed coupling rule bewteen the protocol and calibration tables' name.
We will discuss how those machanism works and how to edit the machanism by configure files in next section.
Yes, you can design your own naming rules and coupling rules to governing varible protocols and the calibration tables with reusing, priorities,
so those complecated rules by several configure files.
In the recon part, the <Axialrebin>
is replaced by <Sloperebin>
, the <Filter>
is skipped,
but more sub tags are added in the <Backprojection>
, two new nodes are employed the <Boneharden>
and <Output>
.
It is a 3D-axial reconstruction job, differ from the textbook algorithms we employed our unpublished method to achieve a 'no cone-artifact' reconstruction
of multi-shots 3D-axial scan. As a part of that work, we modified the rebin algorithm, replaced it by what I named 'sloperebin', for 3D-reconstruction.
The node <Backprojection>
now employed more sub tags,
in which the <upsampling>
is a flag to open the function of the
upsampling of the projection data on channel direction (X-direction). (Sorry for confusing that the <upsampling>
is as same as
<Xupsampling>
, they are exactly same tag.) When the flag <upsampling>
or <Xupsampling>
set to true
the X-upsampling function is open to double-upsample the projection data before the filter, and a tag <upsampgamma>
will be read as the
parameter of the upsampling or a dedault value will be loaded if it is skipped. Appropritate parameters will be helpful in anti alias artifact,
but non-advanced users are not suggest to change that;
in which the <Filter>
is the FBP kernel, when this tag is active the node <Backprojection>
will do filter for the data before the back projection, normally after the X-upsampling. Note that the X-upsampling shall be done before the filter,
so if you want to do the X-upsampling you shall set the <Filter>
in <Backprojection>
but not employ a single <Filter>
node before the backprojection. We didn't offer a single node to do the upsampling;
in which the <FOV>
is the recon FOV, if you set this tag the value in protocol will be ignored;
in which the <method>
is the reocn method, you can select 2D or 3D for axial recon.
If the method 3D is selected the <Sloperebin>
shall be employed,
else if you use 2D the <Sloperebin>
or <Axialrebin>
are both working,
and by the way in calibration jobs only the <Axialrebin>
is permitted;
in which the <Zupsampling>
is a flag of Z-direction upsampling and the <Gamma>
is the paramter of Z-upsampling. The number of <Zupsampling>
is the times of the Z-upsampling, here 4 means 4-times upsampling
(don't worry the memmory this opertator is just technically).
Appropritate parameters will be helpful in anti cone artifacts, but non-advanced users are not suggest to change that.
To set the <Zupsampling>
to 1 and skip the <Gamma>
it will decay to linear interpolation.
All those X and Z upsampling method is based on our 4-point full-pass upsampling algorithm, have a chance I will present the details.
The node <Boneharden>
is a function to anti the bone-beam-harden artifacts. It contians a sub tag <Filter>
to asign the filter used in bone-beam-harden correction and a sub tag <subview>
to asign the view-subspace used in that correcion.
The node <Output>
is to output the images to dicom files.
As we presented, the function CTrecon will return the images like img=CTrecon(...);
to the output arguments img
(in workspace).
To employ the node <Output>
is a more 'standard' way to output the dicom images which will include the necessary dicom tags
for any 3-part software to read them. There are some stories to talk, the detials of the dicom tags, other functions of the <Output>
node,
we will discuss them later.
Here is another sample of the recon .xml configure file, recon_Helical_sample2.xml,
of helical reconstruction.
<?xml version="1.0" encoding="utf-8"?>

The protocol part of this sample is also (almost) copied from the protocol configure in simulation.
The <pipe>
of this sample is a typical pipeline configuration of the helical reconstruction,
the only difference of which to the axial is the <Helicalrebin>
, which is the rebin node specially for helical.
As we discussed there are several rebin different nodes, we haven't integrated those methods together. (I will do that soon.)
To clear this up, we should use <Helicalrebin>
in helical,
use <Sloperebin>
in 3D-axial and use <Axial>
in 2D-axial or calibration.

Sausage and Fennel Pasta
This one was a winter warmer from Jamie Oliver. Simple to make, yummy to eat, and according to the dashing Essex Chef, a ‘superfood’ meal – what’s not to love?
It started with boiling some chipolata sausages, broccoli stalk and chili pepper for a few minutes. Then everything is fried off with onions, garlic, and fennel seeds and oregano. A can of tinned tomatoes was then added and everything bubbled away while we cooked the pasta. The broccoli florets were added to cook with the pasta in the last few minutes then everything was brought together in the pan. We ‘paired’ this dish with a wine from Tesco that was on special. It was a Californian red and the label recommended to drink it with meaty pasta, so it had to be.
When we finished dinner, a cry of ‘I can make apple sauce!’ came from Nathalie. True to her word, twenty minutes later a delicious plate of apple sauce topped with a gingery-oat crumble, raspberry, and (not for Sam) a dollop of plain yoghurt arrived. The perfect light dessert for a hearty meal.
Pesto Chicken and Veg
Impromptu dinner parties are a favourite at 7D, and this meal was one of them.
The conversation for this happened as follows:
Sam already had chicken and broccoli in the fridge, so Rebecca picked up some pesto, and ingredients for a light apple, pear, and avocado salad. The dressing was a mustard and balsamic number, which Laura even ventured to have! Major win.

public interface ThreadContextProvider
Application code must never access the classes within this spi
package. Instead, application code uses the various interfaces that are defined
by the Jakarta Concurrency specification, such as
ManagedExecutorService
and ContextService
.
The ThreadContextProvider
implementation and related classes are
packaged within the third party provider's JAR file. The implementation is made
discoverable via the ServiceLoader
mechanism. The JAR file
that packages it must include a file with the following name and location,
META-INF/services/jakarta.enterprise.concurrent.spi.ThreadContextProvider
The content of the aforementioned file must be one or more lines, each specifying
the fully qualified name of a ThreadContextProvider
implementation
that is provided within the JAR file.
The Jakarta EE Product Provider must use the
ServiceLoader
to identify all available implementations of
ThreadContextProvider
that can participate in thread context capture
and propagation and must invoke them either to capture current thread context or establish
default thread context per the configuration of the
ContextServiceDefinition
,
or vendor-specific configuration, and execution properties such as
ManagedTask.TRANSACTION
that override context propagation configuration.
| Modifier and Type | Method and Description |
|---|---|
ThreadContextSnapshot |
clearedContext(java.util.Map<java.lang.String,java.lang.String> props)
Returns empty/cleared context of the provided type.
|
ThreadContextSnapshot |
currentContext(java.util.Map<java.lang.String,java.lang.String> props)
Captures from the current thread a snapshot of the provided thread context type.
|
java.lang.String |
getThreadContextType()
Returns a human readable identifier for the type of thread context that is
captured by this
ThreadContextProvider implementation. |

by some types of tasks and contextual proxies.
Thread context providers that do not supply or use execution properties
can ignore this parameter.ThreadContextSnapshot clearedContext(java.util.Map<java.lang.String,java.lang.String> props)
This is used in cases where the provided type of thread context should not be propagated from the requesting thread or inherited from the thread of execution, in which case it is necessary to establish an empty/cleared context in its place, so that an action does not unintentionally inherit context of the thread that happens to run it.
For example, a security context provider's empty/cleared context ensures there is no authenticated user on the thread. A transaction context provider's empty/cleared context ensures that any active transaction is suspended. And so forth.
props
- execution properties, which are optionally provided
by some types of tasks and contextual proxies.
Thread context providers that do not supply or use execution properties
can ignore this parameter.java.lang.String getThreadContextType()
ThreadContextProvider
implementation.
To ensure portability of applications, this is typically be a keyword that is defined by the same specification that defines the thread context type.
ContextServiceDefinition
defines identifiers for built-in thread context types, including
Application
,
Security
, and
Transaction
,
as well as the
Remaining
identifer which covers all remaining context.
These identifiers must not be returned from this method.
Applications use a combination of built-in identifiers and those that are
defined by other specifications and third-party context
types when configuring a ContextServiceDefinition
to capture and propagate only specific types of thread context.
For example:
@ContextServiceDefinition(
name = "java:module/concurrent/MyCustomContext",
propagated = MyCustomContextProvider.CONTEXT_NAME,
cleared = { ContextServiceDefinition.SECURITY, ContextServiceDefinition.TRANSACTION },
unchanged = ContextServiceDefinition.ALL_REMAINING)
It is an error for multiple thread context providers of an identical type to be simultaneously available.


Compatibility
Which JDK is required to use ProxyToys?
JDK 5.0 or later, since the 1.0 release. For JDK 1.4, please use ProxyToys 0.21
What are the advantages of using CGLIB based factory over Java Reflection mode?
| Feature | Java Reflection factory | CGLIB factory |
|---|---|---|
| Can proxy public interfaces | Yes | Yes |
| Can proxy public classes | No | Yes |
| Can proxy non-public classes | No | No |
| Can proxy final classes | No | No |
Which CGLIB versions are compatible with ProxyToys?
ProxyToys can run with CGLIB versions 2.2, 2.1, 2.0.2 and 2.0. Note, that the CLIB Java archives cglib-full-2.0.x contain also classes of ASM 1.x. The newer version ASM 2.x is no longer compatible with any version of the plain CGLIB archives, you may use therefore cglib-nodep-2.2 instead.
Our Maven artifact has a transitive dependency on cglib-nodep-2.2, and we intend to keep up with releases of CGLIB going forward.
Are there plans to provide enhanced mode support to other byte code libraries?
Yes. Let us know which library you would like supported. The single precondition is that the library must have a proxy implementation.
Scalability
Is ProxyToys thread safe?
Yes. The Proxy factories have a static builder interface. Starting with ProxyToys 0.2 none of the proxy instances itself created by the individual toys do have any state.
Development
I run the unit tests or ProxyToys in my IDE, but most of them are failing. Did you ever run them?
The unit tests are run with every build of ProxyToys as our CI loop shows. If your IDE collects unit tests automatically, this might be wrong. Instead you have to call explicitly com.thoughtworks.proxy.AllTests.suite().

Southern Ohio native Charlie Haskins has been sharing his colorful and eccentric art skills in the Portsmouth area for years.
Haskins was raised in South Webster, about a 30-minute drive northeast of Portsmouth.

Last year, Haskins had an exhibit at Ohio University’s Southern Campus, located in Ironton.
“It was possibly my favorite exhibit I’ve done. I took it as an opportunity to show off my weirder stuff,” Haskins said. “In the show, I had paintings, sculptures and even made some puppets that hung from the gallery’s ceiling.”
Haskins’ art style consists of creating a story.
“Someone once told me that my painting looked like what Dr. Seuss would make if he had taken a little too much cough syrup, and I tend to agree,” he said.
Haskins is a fourth-generation artist. He said art is his “obsession” and that he is always working on different sketches and drawings — sometimes even on napkins and scrap paper.

“I think I keep making things because it’s how I learn and explore new ideas,” Haskins said.
While folklore legends such as Bigfoot, mermaids and the man in the moon have a large influence on Haskins’ work, he is also really influenced by his mother.
“She has always encouraged me to try new media and to keep the act of art making in my day-to-day life,” he said.
Haskins’ work has been displayed at the Geer Museum and Southern Ohio Museum, as well as events like Comic Con, Nelsonville Music Festival and the Irving Halloween Festival.

One of Haskins’ favorite parts about events, such as festivals and conventions, is setting up the exhibits.
He has been awarded with the Outstanding Individual Artist award from the Portsmouth Area Arts Council.
Haskins believes the role of an artist is a big responsibility in the community.

“They can preserve the past with their work. They improve upon the past. They can make new works. But for me, I think the biggest role as an artist is to take invisible things, like ideas and feelings, and make them tangible,” Haskins said.
In the future, Haskins plans to publish a book filled with a collection of “ghost paintings.” He has been working on that series for a couple of years.
“I hope to continue to create books,” Haskins said.

Select
By Lookup Subtable
This dialog allows you to select glyphs which undergo a transformation described
in the selected lookup subtable.
There are three variants on how the search behaves:
-
The selection will be set to whatever glyphs match the search criteria
-
The selection will be expanded. Anything that was previously selected will
remain so, and anything that matches the search criteria will become selected.
-
The selection will be restricted. Only glyphs previously selected will be
searched, the selection will be restricted to those which match
So if you want to search for all ligatures containing both "f" and "i"...
Search for ligatures containing "f" with "<*> Select Results" set
Then Search for ligatures containing "i" with <*> Restrict Selection"
set

You can request historical custom data in your algorithm using the custom data Symbol object. To learn more about historical data requests, please visit the Historical Data documentation. If there is no custom data in the period you request, the history result will be empty. The following example gets u.s. federal reserve interest rate historical data using the History API.
var interestRate = AddData<TradingEconomicsCalendar>(TradingEconomics.Calendar.UnitedStates.InterestRate).Symbol; // Request 60 days of u.s. federal reserve interest rate history with the interestRate Symbol var interestRateHistory = History<TradingEconomicsCalendar>(interestRate, 60, Resolution.Daily);
interestRate = self.AddData(TradingEconomicsCalendar, TradingEconomics.Calendar.UnitedStates.InterestRate).Symbol # Request 60 days of u.s. federal reserve interest rate history with the interestRate Symbol interestRateHistory = self.History(TradingEconomicsCalendar, interestRate, 60, Resolution.Daily)
