Using JHipster UAA for Microservice Security Permalink to " Using JHipster UAA for Microservice Security"
JHipster UAA is a user accounting and authorizing service for securing JHipster microservices using the OAuth2 authorization protocol.
To distinct JHipster UAA from other “UAA”s such as Cloudfoundry UAA, JHipster UAA is a fully configured OAuth2 authorization server with the users and roles endpoints inside, wrapped into a usual JHipster application. This allows the developer to deeply configure every aspect of the user domain, without restricting on policies by other ready-to-use UAAs.

1. Security claims of microservice architecture Permalink to "1. Security claims of microservice architecture"
Before digging into OAuth2 and its application on JHipster microservices, it’s important to clarify the claims to a solid security solution.
1. Central authentication Permalink to "1. Central authentication"
Since microservices is about building mostly independent and autonomous applications, we want to have a consistent authentication experience, so the users won’t notice their requests are served by different applications with possibly individual security configuration.
2. Statelessness Permalink to "2. Statelessness"
The core benefit of building microservices is scalability. So the chosen security solution shouldn’t affect this. Holding the users session state on server becomes a tricky task, so a stateless solution is highly preferred in this scenario.
3. User/machine access distinction Permalink to "3. User/machine access distinction"
There is a need of having a clear distinction of different users, and also different machines. Using microservice architecture leads to building a large multi-purpose data-center of different domains and resources, so there is a need to restrict different clients, such as native apps, multiple single page applications etc. in their access.
4. Fine-grained access control Permalink to "4. Fine-grained access control"
While maintaining centralized roles, there is a need of configuring detailed access control policies in each microservice. A microservice should be unaware of the responsibility of recognizing users, and must authorize incoming requests.
5. Safe from attacks Permalink to "5. Safe from attacks"
No matter how much problems a security solution may solve, it should be strong against vulnerabilities as best as possible.
6. Scalability Permalink to "6. Scalability"
Using stateless protocols is not a warranty of the security solution is scalable. In the end, there should not be any single point of failure. A counter-example is a shared auth database or single auth-server-instance, which is hit once per request.
2. Understanding OAuth2 in this context Permalink to "2. Understanding OAuth2 in this context"
Using the OAuth2 protocol (note: it’s a protocol, not a framework, not an application) is satisfying all 6 claims. It follows strict standards, what makes this solution compatible to other microservices as well, and remote systems, too. JHipster provides a couple of solutions, based on the following security design:
- Every request to any endpoint of the architecture is performed via an “client”
- A “client” is an abstract word for things like “Angular $http client”, some “REST-Client”, “curl”, or anything able to perform requests.
- A “client” may also be used in conjunction with user authentication, like the Angular $http in the frontend client application
- Every microservice serving resources on endpoints (including the UAA), are resource servers
- Blue arrows show clients authenticate on an Oauth authorization server
- Green arrows show requests on resource servers performed by the client
- The UAA server is a combination of authorization server and resource server
- The UAA server is the owner of all the data inside the microservice applications (it approves automatically access to resource servers)
- Clients accessing resources with user authentication, are authenticated using “password grant” with the client ID and secret safely stored in the gateway configuration files
- Clients accessing resources without user, are authenticated using “client credentials grant”
- Every client is defined inside UAA (web-app, internal, …)
This design may be applied to any microservice architecture independent from language or framework.
As an addition, the following rules can be applied for access control:
- User access is configured using “roles” and RBAC
- Machines access is configured using “scopes” and RBAC
- Complex access configuration is expressed using ABAC, using boolean expressions over both “roles” and “scopes”
- example: hasRole(“ADMIN”) and hasScope(“shop-manager.read”, “shop-manager.write”)
3. Using JHipster UAA Permalink to "3. Using JHipster UAA"
When scaffolding a JHipster microservice, you may choose the UAA options instead of JWT authentication.
Note: the UAA solution is also using JWT, which are addressable to custom configuration as well as JWT, using default Spring Cloud Security.
Basic setup Permalink to "Basic setup"
The very basic setup consists of:
- A JHipster UAA server (as type of application)
- At least one other microservice (using UAA authentication)
- A JHipster gateway (using UAA authentication)
This is the order in which it should be generated.
In addition to the authentication type, the location of the UAA must be provided.
For very basic usage, this setup is working the same way as it does for JWT authentication type, but with one more service.
Understanding the components Permalink to "Understanding the components"
The JHipster UAA server does three things out of the box:
- It serves the default JHipster user domain, containing user and account resource (this is done by gateway in JWT authentication)
- It implements
AuthorizationServerConfigurerAdapter
for OAuth2 and is defining basic clients (“web_app” and “internal”) - It serves the JWT public key on
/oauth/token_key
, which has to be consumed by all other microservices
The choices of a database, cache solution, search engine, build tools and further JHipster options are open to the developer.
When a microservice boots up, it usually expects the UAA server is already up to share its public key. The service first calls /oauth/token_key
to fetch the public key and configure it for key signing (JwtAccessTokenConverter
).
If the UAA is not up, the application will continue to start and fetch the public key at a later time. There are two properties - uaa.signature-verification.ttl
controls how long the key lives before it is fetched again, uaa.signature-verification.public-key-refresh-rate-limit
limits requests to UAA to avoid spamming it. These values are usually left at their default values. In any case, if verification fails, then the microservice will check if there’s a new key. That way, keys can be replaced on the UAA and the services will catch up.
From this point there are two use cases that may happen in this basic setup: user calls and machine calls.
For the user calls, a login request is sent to the gateway’s /auth/login
endpoint. This endpoint uses OAuth2TokenEndpointClientAdapter
to send a request to the UAA authenticating with the “password” grant. Because this request happens on the gateway, the client ID and secret are not stored in any client-side code and are inaccessible to users. The gateway returns a new Cookie containing the token, and this cookie is sent with each request performed from the client to the JHipster backend.
For the machine calls, the machine has to authenticate as a UAA using client credentials grant. JHipster provides a standard solution, described in secure inter-service-communication using feign clients
Refresh Tokens Permalink to "Refresh Tokens"
The general flow for refreshing access tokens happens on the gateway and is as follows:
- Authentication is done via
AuthResource
callingOAuth2AuthenticationService
’s authenticate which will set Cookies. - For each request, the
RefreshTokenFilter
(installed byRefreshTokenFilterConfigurer
) checks whether the access token is expired and whether it has a valid refresh token. - If so, then it triggers the refresh process via
OAuth2AuthenticationService
refreshToken. - This uses the
OAuth2TokenEndpointClient
interface to send a refresh token grant to the OAuth2 server of choice, in our case UAA (viaUaaTokenEndpointClient
). - The result of the refresh grant is then used downstream as new cookies and set upstream (to the browser) as new cookies.
Common mistakes Permalink to "Common mistakes"
Here is a brief list of the very major things a developer should be aware of.
Using the same signing key for production and staging Permalink to "Using the same signing key for production and staging"
It is strictly recommended to use different signing keys as much as possible. Once a signing key gets into wrong hands, it is possible to generate full access granting key without knowing login credentials of any user.
Not using TLS Permalink to "Not using TLS"
If attackers manage to intercept an access token, they will gain all the rights authorized to this token, until the token expires. There are a lot of ways to achieve that, in particular when there is no TLS encryption. This was not a problem in the days of version 1 of OAuth, because protocol level encryption was forced.
Using access tokens in URL Permalink to "Using access tokens in URL"
As of standard, access tokens can be either passed by URL, in headers, or in a cookie. From the TLS point of view, all three ways are secure. In practice passing tokens via URL is less secure, since there several ways of getting the URL from records.
Switching to symmetric signing keys Permalink to "Switching to symmetric signing keys"
RSA is not required for JWT signing, and Spring Security does provide symmetric token signing as well. This also solves some problems, which make development harder. But this is insecure, since an attacker needs to get into one single microservice to be able to generate its own JWT tokens.
4. Secure inter-service-communication using Feign clients Permalink to "4. Secure inter-service-communication using Feign clients"
Currently only JHipster UAA is providing an scalable approach of secure inter-service-communication.
Using JWT authentication without manually forwarding JWTs from request to internal request forces microservices to call other microservices over the gateway, which involves additional internal requests per one master requests. But even with forwarding, it’s not possible to cleanly separate user and machine authentication.
Since JHipster UAA is based on OAuth2, all these problems are solved on protocol definition.
This chapter covers how to get started with this.
Using Eureka, Ribbon, Hystrix and Feign Permalink to "Using Eureka, Ribbon, Hystrix and Feign"
When one service wants to request data from another, finally all these four players come into play. So it is important, to briefly know what each of them is responsible for:
- Eureka: this is where services (un-)register, so you can ask “foo-service” and get a set of IPs of instances of the foo-service, registered in Eureka.
- Ribbon: when someone asked for “foo-service” and already retrieved a set of IPs, Ribbon does the load balancing over these IPs.
So to sum up, when we got a URL like “http://uaa/oauth/token/” with 2 instances of JHipster UAA server running on <IP_ADDRESS>:9999 and <IP_ADDRESS>:9999, we may use Eureka and Ribbon to quickly transform that URL either to “http://<IP_ADDRESS>:9999/oauth/token” or “http://<IP_ADDRESS>:9999/oauth/token” using a Round Robin algorithm.
- Hystrix: a circuit breaker system solving fall-back scenarios on service fails
- Feign: using all that in a declarative style
In real world, there is no warranty of all instances of all services to be up. So Hystrix works as a circuit breaker, to handle failure scenarios in a well-defined way, using fallbacks.
But wiring and coding all these things manually is a lot of work: Feign provides the option of writing Ribbon load balanced REST clients for endpoints registered in Eureka, with fallback implementations controlled using Hystrix, using nothing more then an Java interfaces with some annotations.
So for inter-service-communication, Feign clients are very helpful. When one service needs a REST client to access an “other-service”, serving some “other-resource”, it’s possible to declare an interface like:
@FeignClient(name = "other-service")
interface OtherServiceClient {
@RequestMapping(value = "/api/other-resources")
List<OtherResource> getResourcesFromOtherService();
}
And then, using it via dependency injection, like:
@Service
class SomeService {
private OtherServiceClient otherServiceClient;
@Inject
public SomeService(OtherServiceClient otherServiceClient) {
this.otherServiceClient = otherServiceClient;
}
}
Similar to Spring Data JPA, there is no need to implement that interface. But you may do so, if using Hystrix. Implemented classes of Feign client interfaces act as fallback implementations.
One open issue is, to make this communication secure using UAA. To accomplish this, there should be some request interceptor for Feign, which implements the client credentials flow from OAuth, to authorize the current service for requesting the other service. In JHipster, you use @AuthorizedFeignClients
instead. This is an annotation provided by JHipster, which does exactly that.
Using @AuthorizedFeignClients
Permalink to "Using @AuthorizedFeignClients"
Considering the above Feign client should be used to an “other-service”, which serves protected resources, the interface must be annotated like this:
@AuthorizedFeignClient(name = "other-service")
interface OtherServiceClient {
@RequestMapping(value = "/api/other-resources")
List<OtherResource> getResourcesFromOtherService();
}
note: Due to a bug in Spring Cloud, it’s currently not possible to use a different notation for the service name, as
@AuthorizedFeignClient("other-service")
or
@AuthorizedFeignClient(value = "other-service")
The REST client automatically gets authorized with your UAA server, when there is no valid access token stored in memory.
This approach addresses a scenario when machine request run over a separate OAuth client not referring to an user session. This is important, in particular when entity auditing is used on a request, issued by another request in another service. As an alternative, the access token of the initial request may be forwarded to further calls. Currently, there is no “default solution” provided by JHipster.
5. Testing UAA applications Permalink to "5. Testing UAA applications"
Mocking Feign clients Permalink to "Mocking Feign clients"
Components working with Feign clients should be testable. Using Feign in tests the same way it is used in production would force the JHipster Registry and the UAA server to be up and reachable to the same machine where the tests are run. But in most cases, you don’t want to test that Feign itself works (it usually does), but your components using Feign clients.
To test components, which are using feign clients inside is possible using @MockBean
, which is part of spring boot since 1.4.0.
Here is an example, testing SomeService
works as expected, with mocked values for the client:
@RunWith(SpringRunner.class)
@SpringBootTest(App.class)
public class SomeServiceTest {
@MockBean
private OtherServiceClient otherServiceClient;
@Inject
private SomeService someService;
@Test
public void testSomeService() {
given(otherServiceClient.getResourcesFromOtherService())
.willReturn(Arrays.asList(new OtherResource(...));
someService.performActionWhichInkvokesTheAboveMentionedMethod();
//assert that your application is in the desired state
}
}
So with this technology you are simulating the behavior of the other service, and provide expected resource entity, which would come from the origin. All Beans injecting a client will behave as mocked, so you can focus on the logic of these Beans.
Emulating OAuth2 authentication Permalink to "Emulating OAuth2 authentication"
Using Spring’s integration tests against the REST controllers is usually bypassing the security configuration, since it would make testing hard, when the only intention is to prove the controller is functional doing what it should do. But sometimes, testing a controller’s security behavior is part of testing, too.
For this use-case, JHipster is providing an component called OAuth2TokenMockUtil
, which can emulate a valid authentication without forcing the user or client to exist.
To use this feature, two things have to be done:
1. Enabling security in the mock Spring MVC context and inject the mock util Permalink to "1. Enabling security in the mock Spring MVC context and inject the mock util"
@Inject
private OAuth2TokenMockUtil tokenUtil;
@PostConstruct
public void setup() {
this.restMockMvc = MockMvcBuilders
.webAppContextSetup(context)
.apply(springSecurity())
.build();
}
In this test no single instance of the controller has to be mocked, but the
application’s WebApplicationContext
2. Using the OAuth2TokenMockUtil
Permalink to "2. Using the OAuth2TokenMockUtil"
The util offers a method “oaut2authentication”, which is usable to MockMvc “with” notation. Currently it can be configured to mock a authentication with the following fields:
- username
- roles (Set
) - scope (Set
)
Here is an example:
@Test
public void testInsufficientRoles() {
restMockMvc.peform(
get("url/requiring/ADMIN/role")
<EMAIL_ADDRESS>Sets.newSet("some-scope"), Sets.newSet("ROLE_USER")))
).andExpect(status().isForbidden());
}

Alternatives
A surprising number of people used the string formatting - {:02X}
to convert the numbers to hexadecimal. I think that's sort of the problem with these earlier puzzles - there's a big question of how much of python's built in functionality you should use. I guess since I use string formatting a lot that might make sense as a shortcut in this case.
def rgb_2(r: int, g: int, b: int) -> str:
"""Convert RGB to Hexadecimal
If the values are out of bounds they will be set to the nearest limit
e.g. -1 becomes 0 and 2919 becomes 255
Non-integers will raise an error
Args:
r: red channel (0-255)
g: green channel (0-255)
b: blue channel (0-255)
Returns:
6-digit hexadecimal equivalent of r, g, b
"""
return "".join((f"{max(min(color, 255), 0):02X}" for color in (r, g, b)))
expect(rgb_2(0,0,0)).to(equal("000000"))
expect(rgb_2(1,2,3)).to(equal("010203"))
expect(rgb_2(255,255,255)).to(equal("FFFFFF"))
expect(rgb_2(254,253,252)).to(equal("FEFDFC"))
expect(rgb_2(-20,275,125)).to(equal("00FF7D"))
Not quite so readable, but short.


Part II: Testing with a New Project
EditNow we want to make sure that everything is installed properly - and we want to set up the framework for our game. So we're going to make a new project, open it with FlashDevelop and test that it builds and runs.
From the Command Prompt, enter:
flixel tpl -n "FlixelTut"
This will create a new Flixel project using the blank template in the directory FlixelTut (also naming the project FlixelTut).
Outside of the Command Prompt, launch FlashDevelop. Select File>Open and browse to where your FlixelTut directory was created. It should look something like this:
Open the FlixelTut.hxproj file.
Over on the right side of the screen, you should see your Project. This will contain all the files that the Template generated for us.
Next, let's make sure that our project builds and runs properly. By default, a fresh, new Flixel Template Project will launch the game in the MenuState. So go ahead and double-click to open that file from the project list. This file is a very basic (and empty) example of a FlxState Class. You can think of FlxStates a little bit like 'scenes'. When your game is running, one - and only one - state will be the active state. Anything "added" to that state will be visible and accessible by the player, and, for the most part, will be segregated from other States in your game. They are great for having different sections of your game that are sort of in a bubble from one another, such as the MenuState and the PlayState (where the game is actually played). You'll see that, at least for now, the MenuState only has 3 functions in it: create, destroy, and update. When a State is loaded, its create function is called. This is where you want to initialize all of the things in your state. On the flip side, destroy is called when the state is being unloaded (like when you're switching to a different state). This is where you want to put all your 'clean up' logic. Finally update is where all the real magic happens - update is called every "frame" in your game (usually 60 times per second). When a FlxState's update is called, it will call update on all of the objects that have been added to it. This is basically how everything in your game actually happens. We will get to play with this more later on. For now, we JUST want to see that the whole thing works, so, we're going to add a simple FlxText object to this state.
In the create function, right before the line that says
super.create();
, add a new line and type the following:add(new FlxText(10, 10, 100, "Hello, World!"));
Then save your changes.
The Moment of Truth! Go up to the toolbar in FlashDevelop and choose 'Debug' and 'Flash':
Then, press the blue arrow next to 'Debug' (or hit F5) and you should see:
It worked! You've built and run your first HaxeFlixel code!
At this point, you could try running it for neko, windows, and android to make sure they all work as well if you like. If you run into problems with any of those, double-check your code, check out the OpenFL installation information, and if that doesn't help, let us know on the forums.
This is only a small step towards bigger and better things! In the next part, we'll actually define the game we're going to be building, and start putting it together!

Infos to the games structure
- data is stored in objects appended to window.story.state
- those objects hae to be plain objects/arrays without function because of saving/restore by json (see guide)
- see Inventory how a workaround is done around this
- functions that are used through the game are appended to window.gm (gm for game)
- you can also add more objects to window for better structuring
About the styling
- styling should be preferably done in style.twee or a .css
- but there are some places in twee/js where style-propertie is set directly
States and Attributes
States can apply Modifiers to Attributes.
States can be applied to Characters by:
- Enviroment: onTick f.e. Toxic Air -> Poisoned
- Skills: onUse, onApply f.e. cast Firewall -> self reduce mana over time, enemys damage over time
- Items: onUse, onTick
- Equipment: onEquip, onUnequip,onTick
- Perks: onGain, onLoose
States are separated from their origin, f.e. Healing over time continues while the Healing-Item is already gone.
- in this case they have to keep track on their own and remove themself
States can Stack: each equipment of armor add their own modifiers to the defense. A individual modifier is removed when a single part is removed.
- need to keep link which State caused which modifier
- States have an ID: Boots:DefenseBonus, HealthPotion:HealthRecover
- Modifiers store this ID
States can Mutate: a state can change itself, f.e. infected to infested after duration
States can Override other States: Poison Resist also removes Poisoned

The OKD Orchestrator¶
A Container Runtime Orchestrator for the Origin Community Distribution of Kubernetes (OKD) v3.11 and beyond.
A project sponsored by OpenRiskNet.
OpenRiskNet: Open e-Infrastructure to Support Data Sharing, Knowledge Integration and in silico Analysis and Modelling in Risk Assessment
—Project Number 731075
The OKD Orchestrator is a tool to simplify the cloud-deployment of the OpenShift Origin OKD container runtime. The project contains tools to build base images for cloud providers and then deploy, with minimal effort, a Bastion and OpenShift cluster based on those images.
The reader should have some familiarity with cloud environments (like the AWS EC2 platform) and the RedHat OpenShift Origin/OKD framework.
To run the Simple AWS example discussed in the Orientation, the user is required to have an AWS EC2 account and credentials to allow API access.
The OKD Orchestrator is inspired by the open-source KubeNow project, a cloud-agnostic platform for Docker and Kubernetes.
Don’t Panic! There’s a lot of stuff in this repository but, depending on what you expect to do, you may not need to understand everything that’s going on here.
If you’re new to the OKD Orchestrator, start by familiarising yourself with the Orientation document. Then, before building your first cluster follow the Getting Started guide
Building the Documentation¶
A pre-built HTML rendition of the documentation can be found in the
docs/build
directory, where you’ll find an index.html
file.
The source of this documentation can be found in the orchestrator’s
docs/source
directory. It is written using Sphinx and, once you have
installed the basic tools described in the Getting Started section,
you can be build it from docs
.
To build the HTML version of this documentation move to the docs
directory and execute the following:
$ ./make-docs.sh
The resultant index page will be called build/html/index.html
and it and
the rest of the generated files must be committed to revision control as
changes to the documentation are made.

ipc - System V IPC system calls
int ipc(unsigned int call, int first, int second, int third,
void *ptr, long fifth);
ipc() is a common kernel entry point for the System V IPC calls
for messages, semaphores, and shared memory. call determines which IPC
function to invoke; the other arguments are passed through to the appropriate
call.
User-space programs should call the appropriate functions by their
usual names. Only standard library implementors and kernel hackers need to
know about ipc().
ipc() is Linux-specific, and should not be used in programs intended to
be portable.
On some architectures—for example x86-64 and ARM—there is no
ipc() system call; instead, msgctl(2), semctl(2),
shmctl(2), and so on really are implemented as separate system calls.
msgctl(2), msgget(2), msgrcv(2), msgsnd(2),
semctl(2), semget(2), semop(2), semtimedop(2),
shmat(2), shmctl(2), shmdt(2), shmget(2),
sysvipc(7)
This page is part of release 5.05 of the Linux man-pages project. A
description of the project, information about reporting bugs, and the latest
version of this page, can be found at https://www.kernel.org/doc/man-pages/.

1. Which compounds is the synthesizer going to be most used for?
We assume it is cosmetics, antibiotics, immunosuppressants, anti-cancer drugs, disease prevention agents, pain killers, birth control pills and psychoactives.
2. How does it work?
The WaveAcid Biochemical Synthesizer uses a base cartridge and advanced technology to compile pharmaceutical molecules from inorganic compounds and biochemical precursors.
3. What's a base cartridge?
A base cartridge contains amounts of basically every chemical element and a set of biochemical precursors such as Phenol, Benzene and (R)-4-Hydroxyphenylglycin. It also contains distilled Water, and several gases like Carbondioxide. The cartridge is meant to be exchangeable when empty.
4. How long does a single cartridge last?
Depending on the quantities and amounts that you are printing, a single cartridge might last for 1-15 pills of a substance. Numbers vary immensly between different molecules.
19. How much is one?
At the moment, it is priced at $100+ per cartridge, which might seem like a lot, but depending on its usecase is worth it. For example, if you are living next to a pharmacy and want to print 1200mg over-the-counter cough decongestant, it's not going to be worth it for you. If you are camping in the Canadian forrest however, and you need a broadband antibiotic, you are going to be happy to have it.
5. What's Infrared (IR) Spectroscopy?
It's a technique that uses infrared radiation to excite the molecules of a compound and generates an infrared spectrum of the energy by a molecule as a function of the frequency or a wavelength of light. For example, O-H bonds are stronger than C-H bonds. The measurable result is that O-H bonds vibrate at higher frequencies than C-H bonds. IR Spectroscopy is a method of traditional analytical chemistry and data generated by it generally gets displayed after or during mathematical operations such as Fourier Transform. We use it in our device for intermediate step verification, amongside Nuclear Magnet Resonance.
6. How do you go from chemical elements to inorganic compounds to biochemical precursors?
Substantial amounts of heat are generated by lasers in small chambers. Sequentially executed rounds of chemical reactions lead by an NVIDIA GPU cluster produce inorganic compounds. Single-atom and subatomic manipulation methods were borrowed from recent advances in Quantum Computing.
7. Is this legal?
At the moment this is an advanced research & development effort, not a finished ready-to-use techology or product. Different legislatures are having different ideas about autonomous medicine, similiar to the act of 3D printing guns from CAD files. We are, to the best of our and our attorneys knowledge preparing a safe and universally legal product launch and will update you as we proceed. Ethically, the purity and readiness for human consumption, and advice given by AI (instead of a human doctor or pharmcist) is what matters most. The posession of the printer is universally legal; as is the posession of a base chemical cartridge. The posession and consumption of anything that you could print with it, is a whole different story, and in our opinion, should be up to you. We understand that many countries and states don't see it that way.
8. Are there academically proven (university graduate or doctorate) chemists on your team?
Yes, but this is more of a physics effort than a chemistry effort. Synthesis of even most complex biochemical pharmaceutical compounds, like birth control or antibiotics usually takes weeks but still works in a chemical and biochemical fashion. Since our product and our promise requires to break that down to matters of seconds or minutes, traditional approaches to the study of matter demand cutting-edge advances from other disciplines of science - such as, for example - quantum electronics, photonics, ultra-resolution microscopy, artificial intelligence and particle acceleration.
9. Are there academically proven (university graduate or doctorate) physicists and computer scientists on your team?
Yes, just like there are PhD level chemists involved. Some work with us in a cladestine manner, demanding similiar stages of discretion as Wikileaks demanded for the submission of war crime documentation.
10. Is this effort venture funded?
We are venture funded by strategic partners, and accept crowdfunding as a minor way to participate or support this future-bringing effort.
11. How much computational power do you have available for training your machine learning neural network?
15x liquid-cooled NVIDIA TITAN V graphics cards with about 4 double-precision teraflops each.
It's a technique in analytical chemistry used to identify and seperate components of a mixture, including stereoisomerically chiral components. It uses a moving gas stream of Helium or Nitrogen to carry a sample.
13. What's Nuclear Magnet Resonance (NMR)?
It's a technique that uses a strong magnet field measured in 'Tesla', shielded from any outside disturbances, for whole molecule identification. It does so by harnessing quantum effects of charged atomic nuclei, referred to as spin.
14. What's a Flow-Chemical Microreactor?
It's a very small platine, similiar in size and design to a silicon processor (sometimes even using silicon), that instead of electronic circutis, implements chemical circuits, for example to accomplish Friedel-Craft acylation.
15. What's Electrolysis?
In chemistry and drug synthesis, it's a technique that uses a direct electric current to drive an otherwise non-spontaneous chemical reaction.
16. What's an Intermediate Step or Intermediate Product?
Different pharmaceutical or chemical compounds require, depending on the base cartridge and precursors used, a varying number of intermediate synthesis steps. That is different chemical compounds that occur in the process, before the final product was finished.
17. How do you assure purity for human consumption?
We are using a Palm-Size NMR and are developing a very small implementation of Inductively coupled plasma mass spectrometry (ICP-AES) to make sure there is not even traces of potentially toxic or harmful substances or materials in the intermediate steps or final synthesis product. While the device is still in the work, we are using state-of-the-art HPLC, NMR, IR Spectrometers and a Nanometer Resolution Microscope.
20. What's the projected run-time for a single pill print?
We are aiming for 30 seconds max.
21. Which output formats are supported?
We support pressed pills, capsules, liquids and inhalables.
22. How much is the full device?
We're planning to release it at a $1500 retail price point.
24. What if the side products of chemical reactions are harmful or toxic?
Garbage collection and decomposition is constantly in progress. Disposable outputs from the device are completely harmless, while intermediate steps inside the chambers of course are not. The isolated tank structure and outer vacuum-seperated metal shell of the device makes sure that no toxic compounds ever exit the device. Any toxic compounds that are not needed for further chemical reactions are going to be instantly fragmented into chemical elements.
25. Are you 'mixing' compounds?
The WaveAcid Biochemical Synthesizer is both dealing with mixing ratios, temperature, light and pressure; and is also manipulating molecules on a subatomic level.
26. Which processors are you using?
Different chips serve different computational tasks, such as neural network, sensoric calculatations, operating system and cooling. Floating point operations play a huge role in chemical reactions.
27. Is dosage something you can help with?
We are working on a biosensor similiar to Intel Ventures backed Glucose-monitoring devices that seeks the currently active dose of any pharmaceutical in your blood stream and interstital fluids to cryptographically communicate with the WaveAcid Synthesizer.

Swansea City, Stoke City keen on Celtic midfielder Jonny Hayes?
Celtic midfielder Jonny Hayes has reportedly emerged as a transfer target for Swansea City and Stoke City.
by Darren PlantDespite making just 22 starts and 35 substitute outings since his arrival in 2017, Hayes remains wanted by the Scottish giants, who are keen to extend his contract past the end of the season.
However, according to The Sun, the uncertainty regarding his future has led to interest from two clubs in the Championship.
While Swansea and Stoke have ambitions at either end of the table, both teams are said to be keen on securing the 32-year-old's services in January.
The Irishman is no stranger to English football having represented six different clubs before making the switch to Inverness Caledonian Thistle in 2009.

NMatrix¶ ↑
Fast Numerical Linear Algebra Library for Ruby
Description¶ ↑
NMatrix is a fast numerical linear algebra library for Ruby, with dense and sparse matrices, written mostly in C and C++. It is part of the SciRuby project.
NMatrix was inspired by NArray, by Masahiro Tanaka.
Installation¶ ↑
To install the latest stable version:
gem install nmatrix --pre
However, you will need to install ATLAS with CBLAS (C interface to BLAS) first. Detailed directions can be found here. The requirements for NMatrix are:
-
ATLAS, preferably with CLAPACK (see here for details)
-
a version of GCC or clang which supports C++0x or C++11
-
Ruby 1.9.2+
-
packable 1.3.5 (used for I/O)
If you want to obtain the latest (development) code, you should generally do:
git clone https://github.com/SciRuby/nmatrix.git cd nmatrix/ bundle install bundle exec rake compile bundle exec rake repackage gem install pkg/nmatrix-0.1.0.rc4.gem
Detailed instructions are available for Mac and Linux. We are currently working on Mavericks (Mac OS X) installation instructions, but in general, you'll need Homebrew and should probably use +brew install gcc48+ instead of using the install script.
Documentation¶ ↑
If you have a suggestion or want to add documentation for any class or method in NMatrix, please open an issue or send a pull request with the changes.
You can find the complete API documentation on our website.
Examples¶ ↑
Create a new NMatrix from a ruby Array:
>> require 'nmatrix' >> NMatrix.new([2, 3], [0, 1, 2, 3, 4, 5], dtype: :int64) => [ [0, 1, 2], [3, 4, 5] ]
Create a new NMatrix using the N
shortcut:
>> m = N[ [2, 3, 4], [7, 8, 9] ] => [ [2, 3, 4], [7, 8, 9] ] >> m.inspect => #<NMatrix:0x007f8e121b6cf8shape:[2,3] dtype:int32 stype:dense>
The above output requires that you have a pretty-print-enabled console such
as Pry; otherwise, you'll see the output given by inspect
.
If you want to learn more about how to create a matrix, read the guide in our wiki.
Again, you can find the complete API documentation on our website.

Q1. How did the 'process over product' concept affect the way you tackled the site redesign and rebuild?
The process over ‘process over product’ concept assisted and helped how I dealt with the site redesign and rebuild. I was aware about spending my time focussed on learning. I wanted to avoid getting stuck in a difficult spot and banging my head against the wall where I wouldn't learn. For me a key goal was getting my head more around how CSS grids and Layouts work. I focused on that in the context of wanting to achieve a certain website design.
Q2. What did you think about meditation before reading chapter 2?
I thought that it was something useful and helpful to my life but also something that I ‘will do later’ and ‘will do when I have time.’ It is not something I’ve ever been that good at or had the kind habits of structure to accommodate.
Q3. What new things have you learnt about meditation?
I like the idea of combating in a state of mediation the negative voice that says that you are in meditation with a voice of self kindness. I think that the pulling back to attention after distraction is the difficult and productive zone to develop in.
Q4. Did any of the suggested meditation techniques stand out to you?
I think the idea of sitting like a mountain, having a voice of self kindness in meditation and returning to attention after distraction.
Q5. Any other musings?
In working through these new challenges I imagine myself almost like a boat in rough seas. To get across the sea I can’t push my engine hard and consistently - sometimes I must be rapid, sometimes I must be slow. Sometimes I am charging up a wave and if I go too hard I’ve capsize. I feel like I am getting better at steering this boat through the multiplicity of conditions I am moving through

pnmalias(1) pnmalias(1) NAME pnmalias - antialias a portable anyumap. SYNOPSIS pnmalias [-bgcolor color] [-fgcolor color] [-bonly] [-fonly] [-balias] [-falias] [-weight w] [pnmfile] DESCRIPTION Reads a portable anymap as input, and applies anti-aliasing to background and foreground pixels. If the input file is a portable bitmap, the out‐ put anti-aliased image is promoted to a graymap, and a message is printed informing the user of the change in format. OPTIONS -bgcolor colorb, -fgcolor colorf set the background color to colorb, and the foreground to color to colorf. Pixels with these values will be anti-aliased. by default, the background color is taken to be black, and foreground color is assumed to be white. The colors can be specified in five ways: o A name, assuming that a pointer to an X11-style color names file was compiled in. o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers. o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are floating point numbers between 0 and 1. o For backwards compatibility, an old-X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb. o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers between 0 and 1. (This style was added before MIT came up with the similar rgbi style.) Note that even when dealing with graymaps, background and fore‐ ground colors need to be specified in the fashion described above. In this case, background and foreground pixel values are taken to be the value of the red component for the given color. -bonly, -fonly Apply anti-aliasing only to background (-bonly), or foreground (-fonly) pixels. -balias, -falias Apply anti-aliasing to all pixels surrounding background (-balias), or foreground (-falias) pixels. By default, anti- aliasing takes place only among neighboring background and fore‐ ground pixels. -weight w Use w as the central weight for the aliasing filter. W must be a real number in the range 0 < w < 1. The lower the value of w is, the "blurrier" the output image is. The default is w = 1/3.

I was born in NJ but raised in Puerto Rico. I have some Italian background, but I'm mostly Puertorican (Boricua!). I'm fluent in Spanish, I can read and understand some Italian and Portuguese, I'm also learning some ASL (American Sign Language) I think is so important to be able to communicate with everyone.
I love being part of a mixed culture, I learn so much from my roots and FOOD!
My passion: I LOVE arts & music- From enjoying live concerts to theater, drawings and paintings. Everything that involves embracing creative skills, I'm in! I personally love writing, drawing, painting and singing. I would love to play instruments although I need more practice in that, at least I can play a few notes on the piano and play the flute!
A fun fact: Even though I grew up in an island, I don't know how to swin! I know right! But don't worry I expect learn to swim soon, and confront my fears of drowning. At least I'm getting in the water! I'm also scared of heights, but that doesn't stop me from wanting to skydive!

 The design allowed navigation via phototransistor sensors and a black/white tape sensor. I designed the PCB shown below in Eagle which was used to discern infrared emissions at different frequencies. Through testing we found the best way of colleting the ping pong balls was driving into the center of the arena at different angles and not straight on. Having a flexible scooper was another way that increased our collecting percentage. Functionality of the robot can be seen in the video below.
The purpose of the Smart Alarm Project was to create an interactive alarm clock that requires the user to physically do an action/pose that will turn the alarm off (ie. jumping jacks, yoga sequences, specific dance moves etc.) In order to do this we used a pressure sensitive conductive sheet called velostat. When the alarm goes off the velostat squares light up and once the user puts pressure on them for at least 5 seconds the alarm will turn off. For the full project description and instructable...

Mr. Khoury-Diaz is the co-founder and business development lead of Parkofon, a start-up that delivers an all in one urban commuter device.
Mr. Khoury-Diaz is the founder of Octagon Enterprises. The firm provided analytical and evaluation services to its clients.
Mr. Khoury-Diaz was the Associate Director of New Business Development at Save the Children Federation in Washington DC.
As business development coordinator, Mr. Khoury-Diaz worked closely with Senior Management and presented new opportunities to pursue. He held this position from October 1, 2013 to July 24, 2015.
As financial analyst, Mr. Khoury-Diaz was the financial reconciliation lead between country field offices and the corporate office in Washington, DC.
Mr. Khoury-Diaz acted as Project and Communication Manager for the Hispanic Chamber of Commerce.
Mr. Khoury-Diaz served as a Peace Corps volunteer in Ukraine.
For his Master’s thesis, Mr. Khoury-Diaz developed an ordinary least square (OLS) analysis while interpreting three models. He completed research, developed hypotheses, managed and cleaned data, developed validation techniques during model selection, and tested for various lacks of fit. He used publicly-available, individual-based economic data from the Panel Study of Income Dynamics (PSID) which is the longest running longitudinal household survey in the world. The dataset used in this study from 2013 was collected in 2012 and interviewed 9,063 families with a total of 4,257 variables.
By running a series of models using two income-specific dependent variables, his study explored the effects of independent variables on income earners for year 2012. Based on the University of Michigan’s PSID, the analysis interpreted several variables aimed at providing descriptive analysis. The variables included years of education, health status (at various levels) and whether your job requires a computer, if you took a vacation, commuting time, wealth and expenses related variables, such as, student loan, mortgages, credit/store card debt, medical bills, legal bills, loans from relatives, other debts, checking and saving accounts, contributions to your work pension, whether you cashed your pension, stock ownership, and bonds and insurance ownership. The computation of these models resulted in limited explanations of powers. Using the best model in the analysis, however, the results to the hypothesis are as follows:
Hypothesis 1: In a comparison of income attained in one year, the use of discretionary time is correlated with a higher salary than those without discretionary time.
Result: The use of discretionary time in this study meant taking a vacation, which was positively correlated to an increase in salary.
Hypothesis 2: In a comparison of income generated in one year, those that have good health status and gain more years of education will have a higher salary than those who have bad health status and less educational degrees.
Result: The effects of health status and years of education variables on salary failed to gain significance.
Hypothesis 3: In a comparison of income attained in one year, those with savings and no debt will have a higher salary than those who have little or no savings and debt.
Result: Two of the twelve variables received significance in the wealth and debt categories. The two significant variables suggest that those with savings and no debt have higher salaries. However, ten variables received no significance and therefore the results are limited.
These results demonstrate how several variables can affect your earnings. Vacation, which is an expression of discretionary time, is a significant indicator of having more wealth. Education is not standalone in impacting salary. Other variables impact salary, but further research is necessary to determine what they are. Savings and debt are an indicator of labor income. Outstanding debts have a negative effect on your salary and having more savings positively impacts your salary. If you are in debt, even for a student loan, your salary is negatively affected. In fact, moving between economic brackets does not require an education if an education requires attaining debt. Loans ultimately have a lower effect on salary and can make it more challenging to paying that loan. This is not an endorsement to abstain from higher education.
Khoury-Diaz’s research concludes that next steps should include various research models that delve beyond the PSID survey, potentially with data that provides variables with psychological effects.
Life is joy and joy is life! Pedro is a happy person and what makes him happy is eating, working out and learning new things. He usually tries to do all three things, but not at once.
Because he likes to eat, Pedro enjoys cooking, baking and gardening. If he owned more land, he would love to raise chickens, ducks and cattle organically.
The gym is his haven. Being physical is thearaputic. Recently, he recovered from a 3 year back injury and he's celebrating with workouts six days a week.
In conclusion, what he loves about data science is that the field is evolving and to keep up to date you constantly have to learn. This year, he learned to do programming and analytics in Python, built his own website, and learned how to scrape data from the internet. He doesn't know what he will be doing in 6 months, but whatever it is, he's already excited to tackle it.

Computer Programming: Key Concepts
Algorithms
What are they?
A repeatable process for determining the solution to a problem.
function transportationOptions() {
// Write code here to make this decision tree into an algorithm!
}
Algorithms in Daily Life
- Finding a fruit in the grocery store.
- Alphabetizing name tags.
-
Re-organizing your kitchen to make finding stuff easier.
- Finding keys that you lost.
- Finding something good to watch on TV.
- Washing your car windows.
These are all things that we can repeat over and over again!
Create your own algorithm
Design an algorithm for doing the laundry.

Problem-Solving Method
-
Understand the problem.
- Read or listen to the problem statement.
- What is the input?
- What is the output?
-
Make a plan to solve the problem.
-
Use pictures, charts, graphs, systematic lists, objects.
- Act out the solution to help you devise a plan.
- In Computer Science, we call this plan an algorithm.
-
Carry out the plan.
- Once the plan is conceived and understood, follow it.
- If you have planned well, this is the easy part.
-
Review and reflect on how the problem was solved — once the
problem is solved, reflect on the plan that was used.
The Importance of Pseudocoding
To pseudocode is to write out the steps of solving a problem in
plain language (before you start writing any code).

Pseudocoding Steps
-
Make sure you fully understand the problem.
- Look up any tools you might need.
-
Write down the inputs and outputs of the function.
-
List out the coding structures you might use (loops, variables,
conditional statements).
-
Write comments describing what you are going to do.
- Look it over and then write the code!
Exercise!
Flex your algorithm muscles!

object—an object.
string—a string.
write-to-string, prin1-to-string, and princ-to-string are used to create a string consisting of the printed representation of object. Object is effectively printed as if by write, prin1, or princ, respectively, and the characters that would be output are made into a string.
write-to-string is the general output function. It has the ability to specify all the parameters applicable to the printing of object.
prin1-to-string acts like write-to-string with :escape t, that is, escape characters are written where appropriate.
princ-to-string acts like write-to-string with
:escape nil :readably nil.
Thus no escape characters are written.
All other keywords that would be specified to write-to-string are default values when prin1-to-string or princ-to-string is invoked.
The meanings and defaults for the keyword arguments to write-to-string are the same as those for write.
(prin1-to-string "abc") ⇒ "\"abc\"" (princ-to-string "abc") ⇒ "abc"

The DBMS_OUTPUT package provides the capability to send messages (lines of text) to a message buffer, or get messages from the message buffer. A message buffer is local to a single session. Use the DBMS_PIPE package to send messages between sessions.
The procedures and functions available in the DBMS_OUTPUT package are listed in the following table.
Table 7-2 DBMS_OUTPUT Functions/Procedures
Function/Procedure |
Return Type |
Description |
DISABLE |
n/a |
Disable the capability to send and receive messages. |
ENABLE(buffer_size) |
n/a |
Enable the capability to send and receive messages. |
GET_LINE(line OUT, status OUT) |
n/a |
Get a line from the message buffer. |
GET_LINES(lines OUT, numlines IN OUT) |
n/a |
Get multiple lines from the message buffer. |
NEW_LINE |
n/a |
Puts an end-of-line character sequence. |
PUT(item) |
n/a |
Puts a partial line without an end-of-line character sequence. |
PUT_LINE(item) |
n/a |
Puts a complete line with an end-of-line character sequence. |
