A Situation of Conflict
There is always a time in your life where you find yourself in a conflicting situation. One of the most significant conflicts in my life was my decision to move to the USA for college against my parents' will. They were very hesitant because of the financial investment of a private liberal arts college (even on scholarship), and because of the dangers of my being alone in what they believe was a "wild" country.
In attempting to convince them of the opportunities I would benefit from, it seems as though all they cared about was my safety. This situation was rather conflicting, because on one hand, I knew where they came from. If I were a parent and my only child wanted to go study in a different continent and eventually stay for a career, I would be wary and make sure that she/he would carefully consider this choice.
On the other hand, I could not understand why they would not give me this chance. I had proven to them that I was a cautious, intelligent, street-smart and responsible person, but I felt like their overprotectiveness towards me was preventing me from any opportunities or new life experiences.
I felt angry and frustrated, and spent days without talking to them, slowly becoming more distant. Eventually, I realized that this reaction was childish and not very productive, mostly being the result of immediate emotions rather than careful consideration. I realized that to be more succesful, in family as well as in work relationships, I need to be more in control of my emotions, and think of the most diplomatic approach to solving any conflict I have with somebody.
I chose to write down on paper my reasons for making this choice, which will inadvertently be a decisive one for the many years to come. By writing them down clearly and concisely, my parents will know that it is not a choice I am making on a whim. I wanted them to see that I had thought out of every possible option, and prepared for any possible situations that may arise, good or bad.
For every choice, I wrote the pros and cons, and for every con, I would write a solution- just like a lawyer would do in order to plead a case.
For example:
1) Going to the USA to benefit from excellent education and benefit from the holistic learning exprerience of a campus environment.
Pros: excellent education, great job potential, chances to build solid connexions.
Cons: education isn't as good as expected, bad influences.
Con-solution: Only go to the USA if I get accepted to a top college with excellent faculty. Smartest minds in the nations will decrease the likelihood of bad influences. Will communicate frequently to my parents during the first months so that they know my whereabouts (if this makes them feel better).
And this how I went about to solve one of the most important conflicts in my life: careful thinking, controlling of emotions, and find a practical, diplomatic solution.

Nizhnevartovsk is a city in Khanty-Mansi Autonomous Okrug, Russia. Since the 1960s, the Western Siberian oil boom led to Nizhnevartovsk's rapid growth from a small settlement to a city due to its location beside the Samotlor oil field along the right bank of the Ob River, 30 kilometers (19 mi) from the border with Tomsk Oblast, and the presence of the petroleum industry has made it one of the wealthiest cities in Russia.
Winters are cold and humid, and prevailing wind patterns that blow from the South. The daily mean temperature in January, the city's coldest month, is −25.8 °C (−14.4 °F). Summers are typically warm and humid, but short, with a daily mean temperature of 18.2 °C (64.8 °F) in July. Transitional seasons are short.
Nizhnevartovsk is one of the few cities in Russia that exceeds the population of the administrative center of its federal subject: 251,694.

The NIH recently reported that America's most food insecure populations also tend to have a higher risk of cardiovascular disease. You wonder how long it might take to identify counties suffering from both high food insecurity and high prevalence of heart disease? Turns out, it could be a while. While Feeding America’s Map the Meal Gap provides high quality data on food insecure counties in the US, information on the prevalence of heart disease is harder to find. You Search and it points you to the CDC. After much digging around, you find the data and then spend a while downloading, cleaning and joining it with Feeding America's information on food insecurity. You may have given up well before you could answer the question.
Feeding America Data Commons is here to help! It is an evolving collaboration between Feeding America’s Map the Meal Gap Research Study and Data Commons, the world's largest data knowledge graph, aiming to help everyone, whoever you are - journalist, citizen scientist, student, researcher - to explore food security in the United States and its relationship to climate data and health indicators through scatter plots, timelines, and maps.
The Feeding America Map the Meal Gap annual study aims to understand food insecurity and food costs at the local level in the United States. Data Commons is a free and public resource with over 3 billion time-series, across 90,000 variables from 100+ sources about demographics, health, climate, crops, emissions and much more. This site makes available, in a unified format, Map the Meal Gap data merged with public data from Data Commons.
Oh, and the answer to your question above? It takes a mere minute to show all counties in the US with the prevalence of heart disease and rates of food insecurity (see the chart).
Data Commons can be accessed by anyone via the tools available on datacommons.feedingamerica.org.
Data Commons has benefited greatly from many collaborations. In addition to help from US Department of Commerce (notably the Census Bureau), we have received help from our many academic collaborations, including, UC San Francisco, Stanford University, UC Berkeley and Harvard.
We are looking for more collaborators, both for adding new data to Feeding America Data Commons and for building new and interesting applications of Data Commons. Contact us if you are interested in working with us.

Microservices vs Monolithic architecture
The first question JHipster will ask you is the kind of application you want to generate. You have in fact the choice between two architecture styles:
- A “monolithic” architecture uses a single, one-size-fits-all application, which contains both the front-end AngularJS code, and the back-end Spring Boot code.
- A “microservices” architecture splits the front-end and the back-end, so that it’s easier for your application to scale and survive infrastructure issues.
A “monolithic” application is much easier to work on, so if you don’t have any specific requirements, this is the option we recommend, and our default option.
The rest of this guide is only for people interested in doing a microservices architecture.
Overview
The JHipster microservices architecture works in the following way:
- A gateway is a JHipster-generated application (using application type
microservice gateway
when you generate it) that handles Web traffic, and serves an AngularJS application. There can be several different gateways, if you want to follow the Backends for Frontends pattern, but that’s not mandatory. - The JHipster Registry is a runtime application, using the usual JHipster structure, on which all applications registers and get their configuration from.
- Microservices are JHipster-generated applications (using application type
microservice application
when you generate them), that handle REST requests. They are stateless, and several instances of them can be launched in parallel to handle heavy loads. - The JHipster Console is a monitoring & alerting console, based on the ELK stack.
In the diagram below, the green components are specific to your application and the blue components provide its underlying infrastructure.
The JHipster API gateway
JHipster allows use to generate an API gateway. This gateway is a normal JHipster application, so you can use the usual JHipster options and development workflows on that project, but it also acts as the entrance to your microservices. More specifically, it provides HTTP routing and load balancing, quality of service, security and API documentation for all microservices.
HTTP requests routing using the gateway
When the gateways and the microservices are launched, they will register themselves in the registry (using the eureka.client.serviceUrl.defaultZone
key in the src/main/resources/config/application.yml
file).
The gateway will automatically proxy all requests to the microservices, using their application name: for example, when microservices app1
is registered, it is available on the gateway on the /app1
URL.
For example, if your gateway is running on localhost:8080
, you could point to http://localhost:8080/app1/rest/foos to
get the foos
resource served by microservice app1
. If you’re trying to do this with your Web browser, don’t forget REST resources are secured by default in JHipster, so you need to send the correct JWT header (see the point on security below), or remove the security on those URLs in the microservice’s MicroserviceSecurityConfiguration
class.
If there are several instances of the same service running, the gateway will get those instances from the JHipster Registry, and will:
- Load balance HTTP requests using Netflix Ribbon.
- Provide a circuit breaker using Netflix Hystrix, so that failed instances are quickly and safely removed.
Each gateway as a specific “admin > gateway” menu, where opened HTTP routes and microservices instances can be monitored.
Security
JWT (JSON Web Token)
JWT (JSON Web Token) is an industry standard, easy-to-use method for securing applications in a microservices architecture.
JHispter uses the JJWT library, provided by Stormpath, for implementing JWT.
Tokens are generated by the gateway, and sent to the underlying microservices: as they share a common secret key, microservices are able to validate the token, and authenticate users using that token.
Those tokens are self-sufficient: they have both authentication and authorization information, so microservices do not need to query a database or an external system. This is important in order to ensure a scalable architecture.
For security to work, a JWT secret token must be shared between all applications.
- For each application the default token is unique, and generated by JHipster. It is stored in the
.yo-rc.json
file. - Tokens are configured with the
jhipster.security.authentication.jwt.secret
key in thesrc/main/resources/config/application.yml
file. - To share this key between all your applications, copy the key from your gateway to all the microservices, or share it using the JHipster Registry’s Spring Config Server.
- A good practice is to have a different key in development and production.
OAuth2
This feature is currently in BETA and thus its documentation is not yet complete.
JHipster provides the option to generate a “UAA” (User Account and Authentication) server, based on Spring Security. This server provides OAuth2 tokens for securing the gateway.
Then, the gateway uses Spring Security’s JWT implementation to send JWT tokens to the microservices.
Automatic documentation
The gateway exposes the Swagger API definitions of the services it proxifies so you can benefit from all useful tools like Swagger UI and swagger-codegen.
The “admin > API” menu of a gateway has a specific drop-down list, showing the gateway’s API and all the APIs from the registered microservices.
Using this drop-down list, all microservices APIs are automatically documented, and testable from the gateway.
When using a secured API, security tokens are automatically added to the Swagger UI interface, so all requests work out-of-the-box.
Rate limiting
This is an advanced feature that requires setting up a Cassandra cluster (which is easy to do with the provided Docker Compose configuration).
Gateways provide rate-limiting features, so the number of REST requests can be limited:
- by IP address (for anonymous users)
- by user login (for logged-in users)
JHipster will then use a Cassandra cluster to store request counts, and will send HTTP 429 (too many requests) errors when the limit is exceeded. The default limit per user is 100,000 API calls per hour.
This is an important feature, to protect a microservice architecture from being flooded by a specific user’s requests.
As the gateway secures the REST endpoints, it has full access to the user’s security information, so it can be easily extended to provide specific rate limits depending on the user’s security roles.
To enable rate limiting, open up the application-dev.yml
or application-prod.yml
file and set enabled
to true
:
jhipster:
gateway:
rate-limiting:
enabled: true
The Cassandra cluster needs to be set up and configured. If you use JHipster’s Docker Compose configuration (available in src/main/docker
), this should all work automatically, but here are the detailed steps if you want to set up your cluster manually:
- A working Cassandra cluster should be available.
- A schema with the JHipster rate-limiting tables must be configured, using the
create_keyspace.cql
andcreate_tables.cql
scripts from thesrc/main/resources/config/cql
directory - That cluster must configured in the
application-*.yml
files, using thespring.data.cassandra
keys (a default configuration is already generated)
If you want to add more rules, or modify the existing rules, you need to code them in the RateLimitingFilter
class. Examples of modifications could be:
- Lowering the limit of HTTP calls
- Adding limits per minute or per day
- Removing all limits for “admin” users
Access control policy
By default all registered microservices are available through the gateway. If you want to exclude a specific API from being exposed through the gateway, you can use the gateway’s specific access control policy filter. It is configurable using the jhipster.gateway.authorized-microservices-endpoints
key in the application-*.yml
files:
jhipster:
gateway:
authorized-microservices-endpoints: # Access Control Policy, if left empty for a route, all endpoints will be accessible
app1: /api,/v2/api-docs # recommended dev configuration
For example, if you only want the /api/foo
endpoint of microservice bar
to be available:
jhipster:
gateway:
authorized-microservices-endpoints:
bar: /api/foo
The JHipster Registry
JHipster Registry overview
The JHipster Registry is a runtime application, provided by the JHipster team. Like the JHipster generator, it is an Open Source, Apache 2-licensed application, and its source code is available on GitHub under the JHipster organization at jhipster/jhipster-registry.
The JHipster Registry can be cloned/forked/downloaded directly from jhipster/jhipster-registry, and we recommend you use the same version tag as the one you use for your JHipster generator. As the JHipster Registry is also a JHipster-generated application, you can run it like any other JHipster application:
- run it with
./mvnw
in development, it will use by default thedev
profile and the Eureka Registry will be available at http://<IP_ADDRESS>:8761/. - use
./mvnw -Pprod package
to package it in production, and generate the usual JHipster executable WAR file.
If you’d rather run the JHipster Registry from a Docker image, it is available an Docker Hub at jhipster/jhipster-registry. This image is already pre-configured in the Docker configuration that is provided with each microservice application:
- run
docker-compose -f src/main/docker/jhipster-registry.yml up
to start the JHipster Registry. The Eureka Registry will be available on port8761
of your Docker host, so if it runs on your machine it should be at http://<IP_ADDRESS>:8761/.
Please read our Docker Compose documentation for more information on using the JHipster Registry with Docker Compose.
Securing the JHipster Registry
The JHipster Registry is secured by default. You can login using the usual “admin/admin” login and password that are used in normal JHipster applications.
Applications also connect to the JHipster Registry using that same “admin” user, but use HTTP Basic authentication. So if your microservices cannot access the registry, and you see some “401 authentication error” messages, it is because you have misconfigured those applications.
In order to secure your JHipster Registry:
- You must change the default “admin” password. This password is set using the standard Spring Boot property
security.user.password
, so you can use the usual Spring Boot mechanisms to modify it: you could modify the project’sapplication-*.yml
files, or add aSECURITY_USER_PASSWORD
environment variable. The Docker Compose sub-generator uses the environment variable method. - As your applications will connect to the registry using HTTP, it is very important to secure that connection channel. There are many ways to do it, and the easiest one is probably to use HTTPS.
Application configuration with the JHipster Registry
The JHipster Registry is a Netflix Eureka server and also a Spring Config Server: when applications are launched they will first connect to the JHipster Registry to get their configuration. This is true for both gateways and microservices.
This configuration is a Spring Boot configuration, like the one found in the JHipster application-*.yml
files, but it is stored in a central server, so it is easier to manage.
On startup, your gateways and microservices app will query the Registry’s config server and overwrite their local properties with the ones defined there.
Two kinds of configurations sources are available:
- A
native
configuration, which is used by default in development (using the JHipsterdev
profile), and which uses the local filesystem. - A
Git
configuration, which is used by default in production (using the JHipsterprod
profile), and which stores the configuration in a Git server. This allows to tag, branch or rollback configurations using the usual Git tools, which are very powerful in this use-case.
To manage your centralized configuration you just need to add appname-profile.yml
files in your configuration source where appname and profile correspond to the application’s name and current profile of the service that you want to configure.
For example, adding properties in a gateway-prod.yml
file will set those properties only for the application named gateway started with a prod profile. Moreover, properties defined in application[-dev|prod].yml
will be set for all your applications.
As the Gateway routes are configured using Spring Boot, they can also be managed using the Spring Config Server, for example you could map application app1-v1
to the /app1
URL in your v1
branch, and map application app1-v2
to the /app1
URL in your v2
branch. This is a good way of upgrading microservices without any downtime for end-users.
Creating microservices
Microservices are a type of JHipster applications, that have no front-end (the AngularJS front-end must be generated on a gateway), and which work with the JHipster Registry to be configured and discovered.
Generating entities in a microservices architecture
Using the entity sub-generator works a little bit differently in a microservices architecture, as the front-end and the back-end codes are not located in the same application.
First, generate the entities in the microservices applications: this works as usual, and you can also use JHipster UML or JDL Studio to help you generate complex entities and relationships. As microservices don’t have a front-end, no AngularJS code will be generated.
Then, on the gateway(s), run the entity sub-generator again. A new question will appear at the beginning, which is specific to gateways:
- You will have the choice either to generate an new entity normally (a gateway is also a standard JHipster application, so this would work like for a monolith application), or use an existing JHipster configuration from a microservice.
- If you choose to generate the entity from a microservice, you will need to enter the path to this microservice on your local computer, and then JHipster will generate the front-end code on the gateway.
Distributed caching with Hazelcast
If your application uses an SQL database, JHipster proposes a different 2nd-level caching solution with microservices:
- JHipster’s default caching solution with microservices is Hazelcast
- You can still choose Ehcache (the default solution with monolith applications) or choose not to use a cache at all
This solution is the default with microservices, as in this architecture the idea is that you will scale your services:
- with a local cache, your service instances won’t have a synchronized cache, resulting in incorrect data
- without any cache, the burden of scaling will be pushed to the database, which won’t be very good at it (unless you use our Cassandra option)
Using Hazelcast with microservices will result in a specific configuration:
- At start-up, your application will connect to the JHipster Registry to find if other instances of the same service are running
- With the
dev
profile, JHipster will create a cluster of those instances on localhost (<IP_ADDRESS>
), using a different port per instance. By default, the Hazelcast port isyour application's port + 5701
(so if your application’s port is8081
, Hazelcast will use port13782
) - With the
prod
profile, JHipster will create a cluster with all the other nodes it finds, using the default Hazelcast port (5701
)
Microservices with no database
Only microservices applications can be created without a database. This is because microservices are small and do not have user-management code.
A microservice without a database is very small, and could be used to connect to a specific back-end like a legacy system.
Using Docker Compose to develop and deploy
Working on a microservices architecture means you will need several different services and databases working together, and in that context Docker Compose is a great tool to manage your development, testing and production environments.
A specific section on microservices is included in our Docker Compose documentation, and we highly recommend that you get familiar with it when working on a microservices architecture.
Monitoring with JHipster Console and the ELK stack
When using the Docker-Compose sub-generator, you will be asked if you want to add monitoring to your infrastructure. This option, will add the JHipster-Console to your docker-compose.yml
file. Once started, it will be available on http://localhost:5601 and start to gather your applications’ logs and metrics. For instructions on how to set up monitoring for your applications please refer to the monitoring documentation.
Compared with monolithic applications, gateways and microservices monitoring configuration provide additional features to help you effectively monitor a microservices cluster. For example logs are enriched with each application’s name, host, port and Eureka ServiceId so that you can trace from which service they are originating from. Moreover the JHipster Console comes with default dashboards that give you a view of all your services at the same time.
Production
Going to production with Docker Swarm
As Docker Swarm uses the same API as Docker Machine, deploying your microservices architecture in the cloud is exactly the same as deploying it on your local machine. Follow our Docker Compose documentation to learn more about using Docker Compose with JHipster.
Going to production with CloudFoundry
The CloudFoundry sub-generator works the same with a microservices architecture, the main difference is that you have more applications to deploy:
- Use the sub-generator to deploy first the JHipster Registry (which is a normal JHipster application).
- Note the URL on which your JHipster Registry is deployed. Your applications must all point to that URL:
- In the
bootstrap-prod.yml
file, thespring.cloud.config.uri
must point tohttp://<your_jhipster_registry_url>/config/
- In the
application-prod.yml
file, theeureka.client.serviceUrl.defaultZone
must point tohttp://<your_jhipster_registry_url>/eureka/
- In the
- Deploy your gateway(s) and microservices
- Scale your applications as usual with Cloud Foundry
One important point to remember is that the JHipster Registry isn’t secured by default, and that the microservices are not supposed to be accessible from the outside world, as users are supposed to use the gateway(s) to access your application.
Two solutions are available to solve this issue:
- Secure your Cloud Foundry using specific routes.
- Keep everything public, but use HTTPS everywhere, and secure your JHipster Registry using Spring Security’s basic authentication support
Going to production with Heroku
The Heroku sub-generator works nearly the same with a microservices architecture, the main difference is that you have more applications to deploy:
Deploy a JHipster Registry directly with one click:
Please follow the Heroku sub-generator documentation in order to understand how to secure your JHipster Registry.
Note the URL on which your JHipster Registry is deployed. Your applications must all point to that URL in their application-prod.yml
file. Change that configuration to be:
eureka:
instance:
hostname: <your_jhipster_registry_url>.herokuapp.com
non-secure-port: 80
prefer-ip-address: false
You can now deploy and scale the gateway(s) and microservices. The Heroku sub-generator will ask you a new question, to know the URL of your JHipster Registry: this will allow your applications to fetch their configuration on the Spring Cloud Config server.
Warning The above configuration uses HTTP, but in order to have your architecture secured in production, use HTTPS to connect to the JHipster Registry! As the admin password is sent using HTTP Basic authentication, using an encrypted communication channel is very highly recommended.

Core Features
- Java template engine for XML, XHTML and HTML5. Extensible to other template formats.
- Works both in web and non-web (offline) environments. No hard dependency on the Servlet API.
- Based on modular feature sets called dialects.
- Dialect features (e.g.: evaluation, iteration, etc.) are applied by linking them to template's tags and/or attributes.
- Two dialects available out-of-the-box: Standard and SpringStandard (for Spring MVC apps, same syntax as Standard).
- Developers can extend and create custom dialects.
- Several template modes out-of-the-box (extensible):
- XML: validating against a DTD or not.
- XHTML 1.0 and 1.1: validating against standard DTDs or not.
- HTML5: both XML-formed code and legacy-based HTML5. Legacy non-XML code will be automatically
cleaned and converted to XML form.
- Full (and extensible) internationalization support.
- Configurable, high performance parsed template cache that reduces input/output to the minimum.
- Automatic DOCTYPE translations —from template DTD to result DTD— for (optional) validation of both
template and result code.
- Extremely extensible: can be used as a template engine framework if needed.
- Complete documentation including several example applications.
Standard and SpringStandard Dialects

Re: emonGLCD display not working
This issue has been resolved via email. Thanks to gb09566's troubleshooting skills the issue was identified as a GND plate link on one of the pads of C8 on the rear of the board caused by a PCB manufacturing defect. I will be in touch with the manufacturer to try and resolve this issue. Please post if you have had a similar issue.
So far this is the first problem thats been reported in the 30 or so emonGLCD's sold and 10 or so that we have built up ourselves.
For referance the GLCD voltages as measured on the bottom 20 pins on the GLCD are:
1= 8.27v
2= 7.14v
3= 5.94v
4= 2.53v
5= 1.32v
6= 0 v
7= 2.35v
8= 8.47v
9= 5.76v
10= 2.58v
11= 11.1v
12= 12.53v
13= 0v
14= 4.86v
15= 4.86v
16= 0.12v
17= 0.03v
18= 3.27v
19= 3.27v
20= 0v
The voltage will obviously change depending on what is displayed on the LCD. The voltages above were measured when displaying a single CT power measurement on the screen. The imporatant thing to note is that only pins 6, 13 and 20 should be 0V. A fault could be present if any of the other pin voltages are measured to be 0V
The GLCD can be tested before soldering by inserting the bottom 20 pins (the top 6 pins are only there for stability) in the board then bending them gently at an angle to make contact when powering up the board. Before doing this upload a a demo sketch, I recomend the JeeLabs GLCDd demo that's included in the GLCD library. All pins must make contact as the board is powerd up.
Re: emonGLCD display not working
Hi there - I'm having the same issue,
Leds going on and off, but screen blank?
I have run through the voltages on the pins and they are all close to those above, although 16 seems to be almost zero.
Any tips?
Thanks
Andrew
Re: emonGLCD display not working
Hi, I'm also having a similar problem. enomGLCD was working perfectly for about 2 weeks with solar PV monitor sketch.
PCB is version 1.4. I have checked that capacitors C13 and C14 are mounted correctly (i.e. opposite to polarity shown on silk screen). I've also checked the LCD pin voltages and they are similar to those above and pins 6, 13 and 20 are the only ones that are 0V. I've also checked all the solder joints on the lcd.
The emonGLCD works briefly when powered up but after a few seconds the display goes blank. The sketch continues to run as the LEDs function normally.
Any suggestions?
Thanks, Bill
Re: emonGLCD display not working
Have you checked for dry joints? It would be unusual for a dry joint to show up after only 2 weeks, but it's the next thing to check if you haven't done so already. The symptoms are similar to the problem that the reversed capacitors caused, which caused the voltage multiplier to not work properly. And that it works on power-up and then fades is consistent with that.
I assume you're also checked for anything getting hot?
Re: emonGLCD display not working
I had checked for dry joints and I had already resoldered the 20 pins of the display, however I discovered that the display would occasionally appear if I put pressure along the bottom edge of the board which lead me to believe there may be a bad connection somewhere. I have resoldered the display pins again, being particularly carefull of the pins between the 2 rows of caps which are difficult to access and the display is working again.
I'm slightly embarrassed that it seems to have turned out to be a bad solder joint as I've been soldering since 1979 although it's been a while since I built up any pcbs. On the other hand it's a much easier fix than trying to get the display out!
Re: emonGLCD display not working
Don't worry about that - the plated-through holes do suck up quite a bit of solder and do take a bit more heat. And was it lead-free solder? (I'm dreading my supply of 60-40 running out! I got a 1 lb reel in 1968 and it's looking a bit slim now.) So all's well then.
Re: emonGLCD display not working
Yes, it's been working now for almost 24 hours continuously. Thanks for your help.
It was leaded solder that I bought in about 1980 possibly when I built my ZX80, my real is almost empty too!

This rather special smoked haddock omelette named after the writer Arnold Bennett is a classic restaurant dish and easy to recreate at home.
Pour the milk into a large shallow pan, then add the smoked haddock, bay leaf and peppercorns and bring to a simmer.
Cook for five minutes, or until the fish has just cooked through and flakes when pushed gently.
Lift the fish out of the pan and set aside to cool slightly before gently flaking, discarding the skin.
Meanwhile, strain the milk into a clean pan and beat the eggs together in a separate bowl.
Heat a frying pan until medium-hot, add 15g/½oz of the butter and the eggs and cook gently, stirring with a fork until they just hold together.
Add half the flaked fish to the top of the omelette, then roll out of the pan onto an ovenproof serving dish and top with the remaining fish.
Preheat the grill to hot.
Wipe out the omelette pan and add the remaining 25g/1oz butter and melt, then add the flour and cook stirring well for two minutes. Gradually add the milk, whisking all the time until it forms a smooth sauce. Season the sauce with salt and black pepper. You can add a knob of butter at this stage too if you want to.
Pour the sauce over the top of the omelette, then scatter the grated cheese over the top and place under the grill for 3-5 minutes, or until golden-brown and bubbling.
Serve immediately.

Declarative Programming – Lab 3
Comprehension and Recursion
In these problems you’ll be asked to define several functions in two ways: first with a list comprehension and second with recursion. These two definitions should not depend on one another. The recursive version should not mention the list-comprehension version, and vice-versa.
To allow the two solutions to these problems to co-exist in one file, you need to give them different names. For this tutorial, use the given name for the list-comprehension version, and append Rec to the name for the recursive version. For example, halveEvens should be a function using a list comprehension and halveEvensRec should be a recursive function that behaves the same.
In addition, to verify that both functions work in the same way, you will write and run an appropriate QuickCheck test. You will find the skeletons of the functions in the file lab2.hs, which came packaged with this document.
Note: for these exercises you may not use any library functions other than the ones stated. If you have an additional solution using other library functions, you’re welcome to discuss it during the tutorial.
Exercises
-
- Write a function halveEvens :: [Int] -> [Int] that returns half of each even number
in the list. For example,
halveEvens [0,2,1,7,8,56,17,18] == [0,1,4,28,9]
Your definition should use a list comprehension, not recursion. You may use the functions
div, mod :: Int -> Int -> Int.
- Write an equivalent function halveEvensRec, this time using recursion, not a list comprehension. You may use div and mod again.
- To confirm the two functions are equivalent, write a test function prop_halveEvens and
run the appropriate QuickCheck test.
-
- Write a function inRange :: Int -> Int -> [Int] -> [Int] to return all numbers
in the input list within the range given by the first two arguments (inclusive). For example,
inRange 5 10 [1..15] == [5,6,7,8,9,10]
Your definition should use a list comprehension, not recursion.
- Write an equivalent function inRangeRec, using recursion.
- To confirm the two functions are equivalent, write a test function prop_inRange and
run the appropriate QuickCheck test.
-
- Write a function countPositives to count the positive numbers in a list (the ones
strictly greater than 0). For example,
countPositives [0,1,-3,-2,8,-1,6] == 3
Your definition should use a list comprehension. You may not use recursion, but you will need a specific library function (there is an overview of the most common list functions in the tables prelude-fn1.png and prelude-fn2.png).
- Write an equivalent function countPositivesRec, using recursion and without using
any library functions.
- To confirm the two functions are equivalent, write a test function prop_countPositives
and run the appropriate QuickCheck test.
- Why do you think it’s not possible to write countPositives using only list comprehension, without library functions?
-
- Professor Pennypincher will not buy anything if he has to pay more than £199.00. But,
as a member of the Generous Teachers Society, he gets a 10% discount on anything he buys. Write a function pennypincher that takes a list of prices and returns the total amount that Professor Pennypincher would have to pay, if he bought everything that was cheap enough for him.
Prices should be represented in Pence, not Pounds, by integers. To deduct 10% off them, you will need to convert them into floats first, using the function fromIntegral.
To convert back to ints, you can use the function round, which rounds to the nearest integer.
You can write a helper function discount :: Int -> Int to do this. For example,
pennypincher [4500, 19900, 22000, 39900] == 41760
Your solution should use a list comprehension, and you may use a library function to do the additions for you.
-
Write an equivalent function pennypincherRec, using recursion and without using library functions. You may use your function discount.
- To confirm the two functions are equivalent, write a test function prop_pennypincher
and run the appropriate QuickCheck test.
-
- Write a function multDigits :: String -> Int that returns the product of all the
digits in the input string. If there are no digits, your function should return 1. For example,
multDigits "The time is 4:25" == 40
multDigits "No digits here!" == 1
Your definition should use a list comprehension. You’ll need a library function to determine if a character is a digit, one to convert a digit to an integer, and one to do the multiplication.
- Write an equivalent function multDigitsRec, using recursion. You may use library
functions that act on single characters or integers, but you may not use library functions that act on a list.
- To confirm the two functions are equivalent, write a test function prop_multDigits and
run the appropriate QuickCheck test.
-
- Write a function capitalise :: String -> String which, given a word, capitalises
it. That means that the first character should be made uppercase and any other letters should be made lowercase. For example,
capitalise "edINBurgH" == "Edinburgh"
Your definition should use a list comprehension and library functions toUpper and toLower that change the case of a character.
- Write a recursive function capitaliseRec. You may need to write a helper function; of
the helper function and the main function only one needs to be recursive.
- To confirm the two functions are equivalent, write a test function prop_capitalise and
run the appropriate QuickCheck test.
-
- Using the function capitalise from the previous problem, write a function
title :: [String] -> [String]
which, given a list of words, capitalises them as a title should be capitalised. The proper capitalisation of a title (for our purposes) is as follows: The first word should be capitalised. Any other word should be capitalised if it is at least four letters long. For example,
title ["tHe", "sOunD", "ANd", "thE", "FuRY"]
== ["The", "Sound", "and", "the", "Fury"]
Your function should use a list comprehension, and not recursion. Besides the capitalise function, you will probably need some other auxiliary functions. You may use library functions that change the case of a character and the function length.
- Write a recursive function titleRec. You may use capitaliseRec and any of its auxiliary functions.
- To confirm the two functions are equivalent, write a test function prop_title and run
the appropriate QuickCheck test.

Dragged to work? I can relate to that
by LettersGary Younge | Boris Johnson | Classical music | Japanese honesty | Commons Speaker
Well done, Gary Younge, on your appointment as professor (Report, 6 November). You have a rare talent that makes a reader feel present. I recall a May 2014 article recounting your two meetings with the late Maya Angelou which does it in spades: “As her car pulled away after dropping me off at the hotel, she put her head out of the window, waved, and shouted like a teenage girl: ‘That’s swanky!’ She was 74 and high on life.”

• David Dimbleby’s vox pop sessions for Panorama, previewed on Radio 4, included a woman from Merthyr who declared she would be voting for Boris Johnson because “he has balls of steel”. Does she have any evidence for this assertion? I think we should be told. Even if true, is testicular composition a good basis for our voting decisions?

• I’m happy my colleague Stephen Morris has had his violin returned (Report, 4 November). When I left my viola on a train at West Hampstead in 1990 after a long day in the pub, I never saw it again. I hope it gives its current custodian the pleasure that only a viola can.

• In 1992, while living in Tokyo, I left my bag on a train at Ginza station at around 1pm. At 10.15pm I happened to get on the same carriage going home, and there it was, untouched.

• It’s a shame I was not eligible to be Speaker. I certainly feel like I need to be dragged to work some mornings (MPs vote for Hoyle as new Speaker of the Commons, 5 November).

Instantiate a Remote
to connect to a submergence
service layer hosted on another cluster.
If you use the normal substation
module as a monad and your config includes the APIKey and APIForward keys you will get a
Remote
automatically.
constructor
Remote ( ) {
Arguments
returns
If the new
keyword is not used, an instance is created and returned.
Events
When the last live connection for a client id goes offline, exactly one substation instance in your cluster will emit this event once. It is emitted for every client belonging to a user.
When the first live connection for a client id comes online, exactly one substation instance in your cluster will emit this event once. It is emitted for every client belonging to a user.
Each time a User initiates a new live connection to this substation
instance, this event is
emitted. It offers the client an immediate opportunity to emit events targetted to the
individual connection.
Static Properties
Methods
Reads the remote configuration and compares it to the local instance. If the remote
configuration does not match, the Remote
will do one of the following:
- By default, the process will exit.
- If the APIOverwriteActions option is set, the local configuration is written to the server. If this fails for some reason, the process will exit.
- If the APIAcceptConfig option is set, the discrepency is logged but startup continues.
Once the remote configuration is resolved, actions
have their setup
Functions run. Finally, the port is opened and this
Remote
begins accepting requests.
Arguments
Send an event to a User or User/Client pair with at least one active Socket.io
connection.
These are best-effort events - delivery will not be ensured, just attempted. Messages with
ensured delivery must be handled in the application. Guaranteed delivery like substation
could
provide is of limited value because it only guarantees that the message arrived, not that it was
successfully acted upon.
Makes an http POST
request against the remote service on the path /event
.
Arguments
If present, narrows the User ID selection to this specific User/Client pair.
The argument parameters as they will appear on the client, beginning with the String name of the event to emit.
Arguments
If a technical Error prevented the attempt for proceeding, it is passed here.
Whether a client is expected to receive the event. This result value is produced early,
after connections have been found but before any data has been sent. It is possible, though
unlikely, that one of the selected connections will go offline in the next fistfull of
milliseconds, resulting in a true
for didReceive
when no events were in fact delivered.


[% page.js.push("ntppool.js"); %] [% PROCESS tpl/manage/navigation.html %]
The net speed is used to balance the load between the pool servers. If your connection is asymmetric (like most DSL connections) you should use the lower speed.
The amount of queries your server will get is generally directly proportional to the netspeed, so a 50Mbit setting will get about 5 times more traffic than the 10Mbit setting. The pool will only use a fraction of the "netspeed setting". Be aware that the amount of queries to your server will grow over time.
The "availability score" goes up to 20. It must be higher than 10 for the server to be included in the cluster.
As noted on the join information page adding your IP to the pool is a long term commitment. If you need to remove your server from the pool you can schedule the removal with the delete button (up to 3 months in advance!).
The current NTP implementations (and the pool system) are very IP focused, so to "change" the IP address of your server, please delete the old server and just add the new IP.
To change other server information, email server-owner-help@ntppool.org.

Quesadillas are just fancy for flattened, fried wraps - black beans and cheese fill these with an avocado side salad.
In a bowl, mix together the black beans, cumin, oregano, dried chilli flakes, sliced spring onions, chopped pepper and grated cheese until well combined, using your hands to squash the beans. Season, to taste, with salt and freshly ground black pepper.
Lay the tortillas out on a clean work surface. Rub the cut sides of the garlic clove vigorously all over the tortillas.
Divide the bean mixture between two of the tortillas, spreading the mixture out using a spoon to completely cover the tortillas.
Place the remaining two tortillas on top of the mixture, making sure the sides you rubbed with garlic are facing inwards. Gently press down to form two sandwiches.
Heat a little of the oil in a large frying pan over a medium heat. Add one of the quesadillas to the pan and fry for 3-4 minutes on each side, pressing the quesadillas down from time to time using a spatula, until the tortillas are crisp and golden-brown on both sides and the filling has melted. Remove from the pan carefully and set aside to drain on kitchen paper. Keep warm.
Repeat the process with the remaining oil and tortillas.
Meanwhile, in a small bowl, mix together the coriander, avocado, lime juice and a pinch of salt until well combined. Set aside.
When the quesadillas are cooked, add the pumpkin seeds to the pan they were cooked in. Fry for 1-2 minutes, or until golden-brown, then add them to the coriander and avocado mixture.
To serve, slice each quesadilla into six pieces and divide the slices between two serving plates. Scatter over the remaining coriander leaves, chopped avocado and roasted pumpkin seeds. Garnish the plate with the lime wedges.

How To Grow Guava Crop
Introduction
Guava could be a tiny tree native to the tropical and semitropic regions of the world. they're thought of to possess been originated from the yank country|North American nation} or Central American region so distributed over to different elements of the world. The crop was at the start cultivated for subsistence kind farming, however currently it's developed into the business farming system. Like all the key fruits it's undertaken as a high-density farming technique for additional productivity and quality of fruits. In India, it is a awfully common fruit out there within the market throughout the year at moderate prices.
Soil and climate conditions
Guava plants will grow much in any kind of soil, however the simplest appropriate soil condition is well-drained clay or sandy dirt with high organic content. The pH of the soil ought to be around five to 7. The plants can survive at an elevation of 1600 linear unit higher than ocean level. The climate for guava farming should be dry with distributed precipitation throughout the year. current of air speed isn't suitable for guava trees. Windbreaks are to be planted round the guava trees in areas wherever the wind velocity ranges from fifteen to twenty four kilometre per hour. The minimum precipitation ought to point between a thousand to 2000 metric linear unit and therefore the temperature of the world should be twenty three to 28˚C.
Propagation Techniques of Guava -
Guava plants are propagated either by seeds or by vegetative methods. The seeds are obtained from the ripe fruits and are seeded in raised soil beds of the nursery within the months of August or February. once the seed plants grow to a height of 10-15 cm they're replanted into the most area. The descendant of length 2.5 cm from one seedling is removed and tied to a different exposed rootstock with a polyethylene strip specified the buds are left uncovered. This patch budding is completed within the month of might or June. once propagating through vegetative elements there are 3 potentialities comparable to air layering, cuttings, and mound layering. one in every of the simplest strategies of propagation is air layering with the assistance of growth regulators. Shoots of one cm diameter are chosen and a hoop of length two cm is cut from the world below the bud. The top aspect of the ring is treated with IBA five hundred ppm solution, so it's lined with moist sphagnum moss moss; finally, it's wrapped with a fifteen cm wide polyethylene sheet. each the ends of the polythene are tied. this can be usually tired March. when 35-40 days when the roots would be visible, it is suggested to get rid of the air layers and plant them within the nursery for any growth. annual shoots are used for getting twenty to twenty five cm of the cuttings. These cuttings are swaybacked in two hundred ppm of IBA answer for twenty-four hours so planted into the soil beds. wet in the soil is very important for this method. Mound layering is additionally done for guava propagation. during this process, the mother plants planted at a distance of one-meter x 1 meter are headed back within the month of Gregorian calendar month –August with the assistance of a stub of 5-8 cm higher than the ground. once the shoots emerge from the stub, a hoop of the bark is removed and a mound of soil is ready specified it covers the ringed shoots. inside thirty to forty days the roots develop. Then, they're detached from the mother plant and planted in the nursery.
Fertilizer
The guava plants respond well to inorganic plant foods and organic manures. The standing of soil and therefore the leaf structure will facilitate us verify the fertilizer demand of the plants. the overall fertilizer amount is applied in 3 split doses. 33% of fertilizer is applied in February, another 33% in might or June and the remaining in September. one m at the bottom of the trunk the specified fertilizers are spread. For young plants up to four years scrap or organic manure @ ten kg, 40-200 g of urea, 100-600 g of superphosphate and 40-225 g of muriate of hydroxide are supplied. For plants of 4-7 years FYM @25-50 kilogram, 200-300 g of urea, 600-1000 g of superphosphate and 225- 350 grams of muriate of hydroxide are supplied. For plants higher than seven years age, need fifty kg of FYM, three hundred g of urea, a thousand g of superphosphate and four hundred g of muriate of potash. chemical element and element fertilizers are extremely essential to the crops for fruiting. Micronutrients comparable to ZnSO₄, MgSO₄, MnSO₄, CuSO₄, FeSO₄ and teepol may be sprayed to regulate the bronzing of leaves.
Diseases occurred in crop:
| Name of Disease | Caused by | Symptoms | Management |
|---|---|---|---|
| Algal leaf spot | Alga | Orange, rust-colored, dense, silky tufts on both upper and lower surfaces of leaves which turn reddish-purple in color as they mature; if tufts are scraped away, a thin gray-white or dark-colored necrotic spot remains on the leaf; bark on twigs and branches may be cracked; young stems and fruit may also be attacked. | Ensure trees receive adequate fertilization, irrigation and and are properly pruned to avoid stress on the plants and promote air circulation through the canopy; periodic applications of a copper based fungicide is usually enough to control the disease. |
| Anthracnose | Fungus | Sunken, dark colored lesions on mature fruit which may become covered in pink spores; lesions coalesce to form large necrotic patches on surface of fruit | The primary method of controlling the disease is to plant resistant guava cultivars; both systemic and non-systemic fungicides are effective at controlling the disease and are usually applied shortly before flowering and during fruit development |
| Pseudocercospora leaf spot | Fungus | Small irregularly shaped or roughly circular dark brown lesions with darker brown border on upper surface of leaves; lesions may also be present on stems and fruit; under humid conditions, fungus may sporulate and gray tufts of mycelium may be visible in the center of lesions; lesions may coalesce to form large necrotic patches. | In areas where environmental conditions are conducive to the development of the disease, chemical control using appropriate fungicides is necessary to control the disease; copper-containing fungicides are most effective. |
| Fruit flies | Insect | Depressions in fruit with dark colored puncture wounds; soft, mushy areas on fruit caused by larvae feedign on fruit; development of secondary rots often cause fruit to drop from tree; insects are small flies - the guava fruit fly is approximately 5 mm in length and is black and yellow in color; the Caribbean fruit fly may reach 12-14 mm in length and is yellow-brown with long patterned wings | Infested fruit should be removed and destroyed; plowing around bases of trees infested with guava fruit flies exposes pupae to damaging heat from the sun and to natural enemies; pheromone traps are used successfully in some regions to control guava fruit flies; millions of sterile Caribbean fruit flies are introduced yearly in Florida to control populations on citrus. |
| Guava Weevil | Insect | The adult females lay eggs in small unripe fruits. After hatching, the larva enters the fruit. Once inside the larva feeds on pulp and seeds, causing petrification and premature maturity of fruit. Larva excrement deposited inside fruit causes fermentation. Mature larvae abandon the ripe fruits and pupate underground. | Collect and burn the damaged fruits.

Plants that are full-grown through the graft bear fruit within the third year of planting and therefore the harvest home time is mostly throughout August or Sept for time of year crops whereas harvesting is finished in January or Feb for winter season crops. If a guava tree is ten years previous then the yield of the tree is a hundred kilogram. The yield from grafted plants in guava is 350 kg which of spermatophyte plants is ninety kg per tree. The yield is a smaller amount in the starting years, i.e. 2 year old guava plant yields four or five kg. In high density planting, the yield is seventy five kilogram per tree. On Associate in Nursing average, it's calculable that one square measure of land yields twenty five tonnes of guava fruit.


Sometimes the programmer is not interested in every global constraint,
only some selected ones. Such a filter can be easily implemented with a
user-defined visualizer. Suppose that you are interested in the constraints
all_different/1
and all_distinct/1
only:
%% spec_filter(+Constraint, +Actions): Call fdbg_show for all constraints %% for which intresting_event(Constraint) succeeds. %% %% Use this filter by giving the constraint_hook(spec_filter) option to %% fdbg_on. spec_filter(Constraint, Actions) :- interesting_event(Constraint), fdbg_show(Constraint, Actions). interesting_event(all_different(_)). interesting_event(all_distinct(_)).
Here is a session using the visualizer. Note that the initialization
part (domain/3
events), are filtered out, leaving only the
all_different/1
constraints:
| ?- [library('clpfd/examples/suudoku')]. [...] | ?- fdbg_on(constraint_hook(spec_filter)). % The clp(fd) debugger is switched on % advice | ?- suudoku([], 1, P). all_different([1,<fdvar_1>,<fdvar_2>,8,<fdvar_3>, 4,<fdvar_4>,<fdvar_5>,<fdvar_6>]) fdvar_1 = 1..9 -> (2..3)\/(5..7)\/{9} fdvar_2 = 1..9 -> (2..3)\/(5..7)\/{9} fdvar_3 = 1..9 -> (2..3)\/(5..7)\/{9} fdvar_4 = 1..9 -> (2..3)\/(5..7)\/{9} fdvar_5 = 1..9 -> (2..3)\/(5..7)\/{9} fdvar_6 = 1..9 -> (2..3)\/(5..7)\/{9} [...] all_different([7,6,2,5,8,4,1,3,9]) Constraint exited. P = [...] ; no % advice | ?- fdbg_off. % The clp(fd) debugger is switched off
Note that the failure of spec_filter/2
doesn't cause any unwanted
output.

Overview
When passing PutIntegrationRequest as input to an Aws::Client method, you can use a vanilla Hash:
{
rest_api_id: "String", # required
resource_id: "String", # required
http_method: "String", # required
type: "HTTP", # required, accepts HTTP, AWS, MOCK, HTTP_PROXY, AWS_PROXY
integration_http_method: "String",
uri: "String",
credentials: "String",
request_parameters: {
"String" => "String",
},
request_templates: {
"String" => "String",
},
passthrough_behavior: "String",
cache_namespace: "String",
cache_key_parameters: ["String"],
content_handling: "CONVERT_TO_BINARY", # accepts CONVERT_TO_BINARY, CONVERT_TO_TEXT
}
Represents a put integration request.
Instance Attribute Summary
-
#cache_key_parameters ⇒ Array<String>
rw
Specifies a put integration input's cache key parameters.
. -
#cache_namespace ⇒ String
rw
Specifies a put integration input's cache namespace.
. -
#content_handling ⇒ String
rw
Specifies how to handle request payload content type conversions.
-
#credentials ⇒ String
rw
Specifies whether credentials are required for a put integration.
. -
#http_method ⇒ String
rw
Specifies a put integration request's HTTP method.
. -
#integration_http_method ⇒ String
rw
Specifies a put integration HTTP method.
-
#passthrough_behavior ⇒ String
rw
Specifies the pass-through behavior for incoming requests based on the Content-Type header in the request, and the available mapping templates specified as the
requestTemplates
property on the Integration resource. -
#request_parameters ⇒ Hash<String,String>
rw
A key-value map specifying request parameters that are passed from the method request to the back end.
-
#request_templates ⇒ Hash<String,String>
rw
Represents a map of Velocity templates that are applied on the request payload based on the value of the Content-Type header sent by the client.
-
#resource_id ⇒ String
rw
Specifies a put integration request's resource ID.
. -
#rest_api_id ⇒ String
rw
Specifies a put integration request's API identifier.

Specifies a put integration input's Uniform Resource Identifier (URI).
Instance Attribute Details
#cache_key_parameters ⇒ Array
<String
> (rw)
Specifies a put integration input's cache key parameters.
#cache_namespace ⇒ String
(rw)
Specifies a put integration input's cache namespace.
#content_handling ⇒ String
(rw)
Specifies how to handle request payload content type conversions. Supported values are CONVERT_TO_BINARY
and CONVERT_TO_TEXT
, with the following behaviors:
CONVERT_TO_BINARY
: Converts a request payload from a Base64-encoded string to the corresponding binary blob.CONVERT_TO_TEXT
: Converts a request payload from a binary blob to a Base64-encoded string.
If this property is not defined, the request payload will be passed through from the method request to integration request without modification, provided that the passthroughBehaviors
is configured to support payload pass-through.
Possible values:
- CONVERT_TO_BINARY
- CONVERT_TO_TEXT
#credentials ⇒ String
(rw)
Specifies whether credentials are required for a put integration.
#http_method ⇒ String
(rw)
Specifies a put integration request's HTTP method.
#integration_http_method ⇒ String
(rw)
Specifies a put integration HTTP method. When the integration type is HTTP or AWS, this field is required.
#passthrough_behavior ⇒ String
(rw)
Specifies the pass-through behavior for incoming requests based on the Content-Type header in the request, and the available mapping templates specified as the requestTemplates
property on the Integration resource. There are three valid values: WHEN_NO_MATCH
, WHEN_NO_TEMPLATES
, and NEVER
.
WHEN_NO_MATCH
passes the request body for unmapped content types through to the integration back end without transformation.NEVER
rejects unmapped content types with an HTTP 415 'Unsupported Media Type' response.WHEN_NO_TEMPLATES
allows pass-through when the integration has NO content types mapped to templates. However if there is at least one content type defined, unmapped content types will be rejected with the same 415 response.
#request_parameters ⇒ Hash
<String
,String
> (rw)
A key-value map specifying request parameters that are passed from the method request to the back end. The key is an integration request parameter name and the associated value is a method request parameter value or static value that must be enclosed within single quotes and pre-encoded as required by the back end. The method request parameter value must match the pattern of method.request.`{location}.{name}`
, where location
is querystring
, path
, or header
and name
must be a valid and unique method request parameter name.
#request_templates ⇒ Hash
<String
,String
> (rw)
Represents a map of Velocity templates that are applied on the request payload based on the value of the Content-Type header sent by the client. The content type value is the key in this map, and the template (as a String) is the value.
#resource_id ⇒ String
(rw)
Specifies a put integration request's resource ID.
#rest_api_id ⇒ String
(rw)
Specifies a put integration request's API identifier.
#type ⇒ String
(rw)
Specifies a put integration input's type.
Possible values:
- HTTP
- AWS
- MOCK
- HTTP_PROXY
- AWS_PROXY
#uri ⇒ String
(rw)
Specifies a put integration input's Uniform Resource Identifier (URI). When the integration type is HTTP or AWS, this field is required. For integration with Lambda as an AWS service proxy, this value is of the 'arn:aws:apigateway:<region>:lambda:path/2015-03-31/functions/<functionArn>/invocations' format.
