There was once a child, and he strolled about a good deal, and thought of a number of things. He had a sister, who was a child too, and his constant companion. These two used to wonder all day long. They wondered at the beauty of the flowers; they wondered at the height and blueness of the sky; they wondered at the depth of the bright water; they wondered at the goodness and the power of God who made the lovely world.
They used to say to one another, sometimes, supposing all the children upon earth were to die, would the flowers, and the water, and the sky be sorry? They believed they would be sorry. For, said they, the buds are the children of the flowers, and the little playful streams that gambol down the hill-sides are the children of the water; and the smallest bright specks playing at hide and seek in the sky all night, must surely be the children of the stars; and they would all be grieved to see their playmates, the children of men, no more.
There was one clear shining star that used to come out in the sky before the rest, near the church spire, above the graves. It was larger and more beautiful, they thought, than all the others, and every night they watched for it, standing hand in hand at a window. Whoever saw it first cried out, “I see the star!” And often they cried out both together, knowing so well when it would rise, and where. So they grew to be such friends with it, that, before lying down in their beds, they always looked out once again, to bid it good-night; and when they were turning round to sleep, they used to say, “God bless the star!”
But while she was still very young, oh very, very young, the sister drooped, and came to be so weak that she could no longer stand in the window at night; and then the child looked sadly out by himself, and when he saw the star, turned round and said to the patient pale face on the bed, “I see the star!” and then a smile would come upon the face, and a little weak voice used to say, “God bless my brother and the star!”
And so the time came all too soon! when the child looked out alone, and when there was no face on the bed; and when there was a little grave among the graves, not there before; and when the star made long rays down toward him, as he saw it through his tears.
Now, these rays were so bright, and they seemed to make such a shining way from earth to Heaven, that when the child went to his solitary bed, he dreamed about the star; and dreamed that, lying where he was, he saw a train of people taken up that sparkling road by angels. And the star, opening, showed him a great world of light, where many more such angels waited to receive them.
All these angels, who were waiting, turned their beaming eyes upon the people who were carried up into the star; and some came out from the long rows in which they stood, and fell upon the people’s necks, and kissed them tenderly, and went away with them down avenues of light, and were so happy in their company, that lying in his bed he wept for joy.
But, there were many angels who did not go with them, and among them one he knew. The patient face that once had lain upon the bed was glorified and radiant, but his heart found out his sister among all the host.
His sister’s angel lingered near the entrance of the star, and said to the leader among those who had brought the people thither:
“Is my brother come?”
And he said “No.”
She was turning hopefully away, when the child stretched out his arms, and cried, “O, sister, I am here! Take me!” and then she turned her beaming eyes upon him, and it was night; and the star was shining into the room, making long rays down towards him as he saw it through his tears.
From that hour forth, the child looked out upon the star as on the home he was to go to, when his time should come; and he thought that he did not belong to the earth alone, but to the star too, because of his sister’s angel gone before.
There was a baby born to be a brother to the child; and while he was so little that he never yet had spoken word he stretched his tiny form out on his bed, and died.
Again the child dreamed of the open star, and of the company of angels, and the train of people, and the rows of angels with their beaming eyes all turned upon those people’s faces.
Said his sister’s angel to the leader:
“Is my brother come?”
And he said “Not that one, but another.”
As the child beheld his brother’s angel in her arms, he cried, “O, sister, I am here! Take me!” And she turned and smiled upon him, and the star was shining.
He grew to be a young man, and was busy at his books when an old servant came to him and said:
“Thy mother is no more. I bring her blessing on her darling son!”
Again at night he saw the star, and all that former company. Said his sister’s angel to the leader:
“Is my brother come?”
And he said, “Thy mother!”
 And he stretched out his arms and cried, “O, mother, sister, and brother, I am here! Take me!” And they answered him, “Not yet,” and the star was shining.
He grew to be a man, whose hair was turning gray, and he was sitting in his chair by the fireside, heavy with grief, and with his face bedewed with tears, when the star opened once again.
Said his sister’s angel to the leader: “Is my brother come?”
And he said, “Nay, but his maiden daughter.”
And the man who had been the child saw his daughter, newly lost to him, a celestial creature among those three, and he said, “My daughter’s head is on my sister’s bosom, and her arm is around my mother’s neck, and at her feet there is the baby of old time, and I can bear the parting from her, God be praised!”
And the star was shining.
 And one night as he lay upon his bed, his children standing round, he cried, as he had cried so long ago:
“I see the star!”
They whispered one to another, “He is dying.”
And he said, “I am. My age is falling from me like a garment, and I move towards the star as a child. And O, my Father, now I thank Thee that it has so often opened, to receive those dear ones who await me!”
And the star was shining, and it shines upon his grave.


Server-side rendering (SSR) is a popular technique for rendering a client-side single page application (SPA) on the server and then sending a fully rendered page to the client. This allows for dynamic components to be served as static HTML markup.
This approach can be useful for search engine optimization (SEO) when indexing does not handle JavaScript properly. It may also be beneficial in situations where downloading a large JavaScript bundle is impaired by a slow network.
In this tutorial, you will initialize a React app using Create React App and then modify the project to enable server-side rendering.
Warning: The code provided in this tutorial is for educational purposes and is not intended for production use. Alternatively, Next.js offers a modern approach to creating static and server-rendered applications built with React.
At the end of this tutorial, you will have a working project with a client-side React application and a server-side Express application.
To complete this tutorial, you will need:
This tutorial was verified with Node v14.4.0, npm
v6.14.5,
react
v16.13.1, @babel/core
v7.10.4,
webpack
v4.42.0, express
v4.17.1,
nodemon
v2.0.4, and npm-run-all
v4.1.5.
First, we use npx to start up a new React app using the latest version of Create React App.
Let’s call our app my-ssr-app:
Then, we cd
into the new directory:
cd my-ssr-app
Finally, we start our new client-side app in order to verify the installation:
You should see an example React app display in your browser window.
Now, let’s create a <Home>
component:
Next, add the following code to the Home.js
file:
src/Home.js
This will create a

heading with a
"Hello"
message directed to a name.
Next, let’s render the <Home>
in the
<App>
component. Open the App.js
file:
Then, replace the existing lines of code with these new lines of code:
src/App.js
This passes along a name
to
<Home>
component so the message that we expect to
display is "Hello Sammy!"
.
In our app’s index.js
file, we’ll use ReactDOM’s
hydrate
method
instead of render
to indicate to the DOM renderer that we’re
rehydrating the app after a server-side render.
Let’s open the index.js
file:
Then, replace the contents of the index.js
file with the
following code:
index.js
That concludes setting up the client-side, we can move on to setting up the server-side.
Now that we have our app in place, let’s set up a server that will send along a rendered version. We’ll use Express for our server. Let’s add it to the project by entering the following command in your terminal window:
Or, using yarn:
Next, create a server
directory next to the app’s
src
directory:
Then, create a new index.js
file that will contain the
Express server code:
Add the imports that will need and define some constants:
server/index.js
Next, add the server code with some error handling:
server/index.js
As you may see, we can import our <App>
component from
the client app directly from the server.
Three important things are taking place here:
build
directory
as static files.
ReactDOMServer
,
renderToString
, to render our app to a static HTML string.
index.html
file from the built
client app, inject our app’s static content in the

with an id
of "root"
,
and send that as the response to the request.
npm
Scripts
For our server code to work, we’ll need to bundle and transpile it, using webpack and Babel. To accomplish this, let’s add the dev dependencies to the project by entering the following command in your terminal window:
Or, using yarn:
Note: An earlier version of this tutorial installed
babel-core
, babel-preset-env
, and
babel-preset-react-app
. These packages have since been
archived, and the mono repo versions are utilized instead.
Next, create a Babel configuration file in your project’s root directory:
Then, add the env
and react-app
presets:
.babelrc.json
Note: An earlier version of this tutorial used a
.babelrc
file (no .json
file extension). This
was a configuration file for Babel 6, but this is no longer the case for
Babel 7.
Now, we will create a webpack config for the server that uses Babel Loader
to transpile the code. Start by creating the
webpack.server.js
file in your project root directory:
Then, add the following configurations to the
webpack.server.js
file:
webpack.server.js
With this configuration, our transpiled server bundle will be output to
the server-build
folder in a file called
index.js
.
Note the use of target: 'node'
and
externals: [nodeExternals()]
from
webpack-node-externals
, which will omit the files from
node_modules
in the bundle; the server can access these files
directly.
This completes the dependency installation and webpack and Babel configuration.
Now, we will revisit package.json
to add helper
npm
scripts:
We will add dev:build-server
, dev:start
, and
dev
scripts to the package.json
file to build
and serve our SSR application easily:
package.json
The dev:build-server
script sets the environment to
"development"
and invokes webpack
with the
configuration file we created earlier. The dev:start
script
invokes nodemon
to serve the built output.
The dev
script invokes npm-run-all
to run in
parallel
the build
script and all scripts that
start with dev:*
- including
dev:build-server
and dev:start
.
Note: You will not need to modify the existing
"start"
, "build"
, "test"
, and
"eject"
scripts in the package.json
file.
We use nodemon
to restart the server when we make changes to
it. And we use npm-run-all
to run multiple commands in
parallel.
Let’s install those packages now by entering the following commands in your terminal window:
Or, using yarn:
With this in place, you can run the following to build the client-side
app, bundle and transpile the server code, and start up the server on
:3006
:
Or, using yarn:
Our server webpack config will watch for changes and our server will restart on changes. For the client app, however, we currently still need to build it each time we make changes. There’s an open issue for that here.
Now, open http://localhost:3006/
in your web browser and you
will see your server-side rendered app.
Previously, the source code revealed:
But now, with the changes you made, the source code reveals:
The server-side rendering successfully converted the
<App>
component into HTML.
In this tutorial, you initialized a React application and enabled server-side rendering.
With this post, we just scratched the surface at what’s possible. Things tend to get a bit more complicated once routing, data fetching, or Redux also need to be part of a server-side rendered app.
One major benefit of using SSR is having an app that can be crawled for its content, even for crawlers that don’t execute JavaScript code. This can help with search engine optimization (SEO) and providing metadata to social media channels.
SSR can also often help with performance because a fully loaded app is sent down from the server on the first request. For non-trivial apps, your mileage may vary because SSR requires a setup that can get a bit complicated, and it creates a bigger load on the server. Whether to use server-side rendering for your React app depends on your specific needs and on which trade-offs make the most sense for your use case.

Disposition – Building Renovations (VIII.6.)
A successful building renovation usually means that the property will be sold to a building operator.
•Same disposition considerations as the building developer selling to the building operator.
When the property can no longer be renovated to accommodate the existing use, it may be sold to a property redeveloper. In which case the following considerations must be met:
•Seller/buyer financing
•Seller representations and warranties
•Seller's limited liability exposure for the future
•Contingencies to close

if nothing appears, then msig.1 takes the lead
after 2 seconds if nothing, then msig.2 takes the lead
that is for the first signature
then once there is a single signature tx in the mempool, the next msig.id has one second to sign and broadcast
if not, then first+2, first+3, ... to N-M-1
now we have a 2 signature tx, so the msig.second+1 is eligible the first timeslot
second is the msig.id of the second signer

Tucked away in our subconsciousness is an idyllic vision. We see ourselves on a long trip that spans the continent. We are traveling by train. Out the windows, we drink in the passing scene of cars on nearby highways, of children waving at a crossing, of cattle grazing on a distant hillside, of smoke pouring from a power plant, of row upon row of corn and wheat, of flatlands and valleys, of mountains and rolling hills, of city skylines and village halls.Tucked away in our subconsciousness is an idyllic vision.

This project allows you to practice the concepts and techniques learned in this module and apply them in a concrete project. This module explored asyncronous action creators in Redux. In your project you will demonstrate proficiency of these subjects and principles by building an app from scratch that consumes and API of your choosing, and displays data fetched from that API.
Read these instructions carefully. Understand exactly what is expected before starting this project.
Commit your code regularly and meaningfully. This helps both you and your team lead in case you ever need to return to old code for any number of reasons.
In this project you’ll choose an api to consume. You will build an application from scratch that uses your chosen API and displays the data you are getting from it.
cd react-redux-app
cd
into the react appyarn start
or npm start
<firstName-lastName>
.<firstName-lastName>
branch, committing changes regularly.<firstName-lastName>
.Follow these steps for completing your project.
This is the chance to let your skills shine! You have learned sooo much the last month, and now you get to put all of your hard-earned skills to work. Choose an open api (this list has a lot of great ones - look for ones with Auth: no
and HTTPS: yes
- or just do a google search for open apis
). Protip - don’t take too long choosing an API. Pick one that looks interesting, and get building.
Once you have chosen an API to consume, build an app that makes sense for the data you will be retrieving. Have fun with this. You get to be the creative mind. You get to make all the decisions here. I’m excited to see what you build!
Take the app as far as you can go! Styling, redux hooks, another API, an input to fetch data dynamically, etc. Work on it, improve it until the end of the day. If you find yourself finishing with time left to spare, jump on with your TL or fellow student to ask them what feature they think you should build next. Good luck!

A board is an storage location to store files for personal use, with your team, or publicly with the world. A board defines four operations to manage pins in any storage system: create, find, retrieve and remove. A board can be read-only if it only supports the retrieve and find operations.
The defaul board in the pins
package is a files-based; meaning, remote files are stored in the file system assigned to your R session. When using this from your personal computer, this defaults to a pins
folder under the default home folder for your user.
RStudio Connect can be used to share pins within your organization, to use this feature you will need to configure a publishing account in RStudio.
To make RStudio Connect your default board run:
Once this board is active, pin()
and pin_get()
will default to use RStudio connect. For instance, we can retrieve the latest world news and pin them to RStudio Connect as follows:
library(xml2)
data.frame(title = xml_text(xml_find_all(read_xml("http://feeds.bbci.co.uk/news/rss.xml"), "///item/title/node()"))) %>%
pin("worldnews", "A table with the latests world news from the BBC")
When using multiple publishing servers, you can specify an specific server through register_board("rsconnect", "<server-name>")
.
When using pins
within RMarkdown documents that you want to run at a given schedule, like rstudio-world-news.Rmd, you can simply push to RStudio Connect since the output pin will be generated as Output Files.
If the boards that the pins
package provides are not sufficient, say, you might want to store your pins in Google Drive; you can still implement custom boards by implementing a few S3 methods. It is advisable to create an R package that provides these methods, but you can also define them in a plain R script.
The following example creatse a simple folder-bard board; probably not suitable for real use cases since all your pins would be lost whenever the R session restarts; however, it’s a simple example that you can use to start developing custom boards:
board_initialize.folder <- function(board, ...) {
if (!dir.exists("pins")) dir.create("pins")
board
}
board_pin_create.folder <- function(board, path, name, description, type, metadata) {
file.copy(path, file.path("pins", paste0(name, ".", type)))
}
board_pin_get.folder <- function(board, name) {
path <- dir("pins", name, full.names = T)
attr(path, "pin_type") <- tools::file_ext(path)
path
}

The full source code for the tutorial is available on GitHub couchbaselabs/try-cb-golang.
The primary focus of the tutorial is to explain the function and theory behind the Couchbase Java client and how it works together with Couchbase Server, and especially new features in versions 4.0/4.5 like N1QL
, FTS
and sub-document
.
It makes use of the travel-sample
data set.
The code that generates the web application is provided with the source code, but is not discussed in this tutorial.
Specific Go prerequisites and set up
In addition to the prerequisites mentionned in Sample Application, you’ll need:
-
Go 1.6+
To get set up for the tutorial proper, follow these steps:
-
mkdir try-cb-golang
-
cd try-cb-golang
-
export GOPATH=$PWD
-
go get github.com/couchbaselabs/try-cb-golang
-
cd src/github.com/couchbaselabs/try-cb-golang
-
if you don’t want to connect to localhost, change the configuration in
main.go
(eg.cbConnStr
) . -
go run main.go
-
You should now be able to access the UI on localhost:8080
| If you want to code it yourself, there’s currently no "fill-in-the-blanks" branch so you’ll have to delete method bodies and try to take it from there. |
| This tutorial focuses on querying through N1QL and FTS rather than views. If you want information about using views, see 6.0@server:learn:views/views-intro.adoc. |
Walking Through the API
The following sections lead you through the primary functions of the sample application.
All of the REST API application code is in the main.go
file.
The following shows you how to program with the various features and services of Couchbase including: connecting to a cluster and bucket, key/value iteraction, document query through N1QL and full text searches.
Configure and Bootstrap the SDK
Where: main()()
Goals: Connecting to the Cluster
and getting a reference to a Bucket
, learn to reuse it.
Relevant Documentation Topics: Managing Connections Using the Go SDK with Couchbase Server
The first step is to let the application connect to your cluster and obtain a reference to a Bucket
(the Bucket is your entry point for the whole storage API).
The cbConnStr
variable defines the connection string including hostname and protocol for your cluster.
The cbBucket
and cbPassword
variables are used separately and get passed to OpenBucket
to actually establish a connection to your bucket.
Connecting to the Cluster and Bucket
globalCluster, err = gocb.Connect(cbConnStr)
// error handling elided...
cluster.Authenticate(gocb.PasswordAuthenticator{
Username: "Administrator",
Password: "something",
})
// For RBAC, in Couchbase Server 5.0 and up
globalBucket, err = globalCluster.OpenBucket(cbBucket, cbPassword)
// error handling elided...
Both bucket and cluster can be managed through the SDK as well (eg. add views or create new buckets), see Managing Clusters Using the Go SDK with Couchbase Server for more information.
Managing Users using Key/Value API
Where: UserLogin() and UserSignup()
Goals: Use Bucket
operations and discover the Document
API.
Relevant Documentation Topics: CRUD Document Operations using the Go SDK with Couchbase Server, Asynchronous Progamming Using the Go SDK with Couchbase Server, Sub-Document Operations
Couchbase is a document oriented database which provides access to your data both through its document ID (for high performance access), as well as through views and N1QL (as powerful query languages).
This is noticeable in the API, where the methods reflect Key/Value operations (RetrieveIn
, Upsert
, etc...) and work with a Sub Document
interface that has an id()
and requests specific content from the document.
The default Document implementation accepts a simple representation of JSON as its content.
Creating New Users
A new user first goes through the UserSignup()
method which recieves a POST of username
and password
encoded as a JSON object.
After registering the user to Couchbase, it uses a JWT encoded version of the username to maintain the session.
The JWT token is later used through further interaction to validate the user session and is created using a custom function createJwtToken()
.
The "user::" prefix is arbitrary to this application, this is just a convention that the application uses to obtain unique keys and have additional information in it, but the key could have been anything else (even sequence numbers or UUIDs).
|
Here comes the part where the Couchbase API is used to store the document.
It’s rather simple, the application uses an Insert
method which stores the document, if the record already exists, an error is returned instead:
globalBucket.Insert(userKey, user, 0).
The resulting JSON data and confirmation is sent back to the client with a success, or an exception if it failed.
|
When it comes to storing a document, you have a choice of three methods:
|
So the result just contains a JWT (Json WebToken) to identify the new user.
If there is a problem, an error and non-successful status code will be returned to the application.
But what is this narration
object in the Result?
The frontend understands this second part of the Result, the narration, as something that it can display in a console, so that users of the application can directly get an idea of what is going on on the server side while browsing the app. It is similar to a log, but transmitted to the frontend.
Checking Login by Getting the User’s Document
In the UserLogin()
method, the application checks a User’s credential and for that it needs to retrieve the corresponding document.
Since user documents are identified by prefixing their username with user::
, this is pretty simple.
Using the sub-document LookupIn(…).Get("password")
the application can request only the precise values it needs from the document, in this case the password:
globalBucket.LookupIn(userKey).Get("password").Execute()
If that particular key doesn’t exist, the LookupIn()
method returns ErrKeyNotFound
.
This is useful to check whether the user exists at all.
Otherwise it’s just a matter of checking the hashed password with the one provided by the user, and responding accordingly.

Relevant Documentation Topics: N1QL Queries Using the Go SDK with Couchbase Server.
In the SDK, there is an ExecuteN1qlQuery
method, which accepts a N1qlQuery
structure and performs a N1QL query against the cluster.
| N1QL is a super-set of SQL, so if you’re familiar with SQL you’ll feel at ease. |
Statements can be provided either in string form or using the DSL.
The application needs to select just the airport name from relevant documents in the bucket. Since it wants to filter relevant document on a criteria that depends on the input length, the query starts with "SELECT airportname FROM `travel-sample`".
Then the application can choose the correct fields to look into depending on the length of the input.
The user can enter either a ICAO or FAA code or a full name of an airport to search for, so the application accommodates each scenario as it builds the N1QL statement.
It also uses wildcards (%
) in the statement to give a free form expression:
var queryStr string
if len(searchKey) == 3 {
queryStr = fmt.Sprintf("SELECT airportname FROM `travel-sample` WHERE faa='%s'", strings.ToUpper(searchKey))
} else if len(searchKey) == 4 && searchKey == strings.ToUpper(searchKey) {
queryStr = fmt.Sprintf("SELECT airportname FROM `travel-sample` WHERE icao ='%s'", searchKey)
} else {
queryStr = fmt.Sprintf("SELECT airportname FROM `travel-sample` WHERE airportname like '%s%%'", searchKey)
}
The statement is ready!
You can execute this statement by wrapping it in a N1qlQuery()
using gocb.NewN1qlQuery(queryStr)
and invoking globalBucket.ExecuteN1qlQuery()
.
Here it is very simple, no placeholders and no particular tuning of the query is necessary, so the simple method: globalBucket.ExecuteN1qlQuery(q, nil)
will be used.
The results of the query are return in a result
object, which can then be iterated over to build an array of the results:
respData.Data = []jsonAirport{}
var airport jsonAirport
for rows.Next(&airport) {
respData.Data = append(respData.Data, airport)
airport = jsonAirport{}
}
More Complex Queries: Finding Routes
Where: FlightSearch()
Goals: Let the DSL guide you into making more complex N1QL queries.
Relevant Documentation Topics: N1QL Queries Using the Go SDK with Couchbase Server.
In this class, there are two more complex queries. The first aims at transforming the human-readable airport name for the departure and arrival airports to FAA codes:
SELECT faa AS fromAirport FROM `travel-sample` WHERE airportname = "Los Angeles Intl"
UNION SELECT faa AS toAirport FROM `travel-sample` WHERE airportname = "San Francisco Intl"
The second aims at constructing the result set of available flight paths that connect the two airports:
SELECT a.name, s.flight, s.utc, r.sourceairport, r.destinationairport, r.equipment
FROM `travel-sample` AS r
UNNEST r.schedule AS s
JOIN `travel-sample` AS a ON KEYS r.airlineid
WHERE r.sourceairport = "LAX" AND r.destinationairport = "SFO" AND s.day = 6
ORDER BY a.name ASC
Yes, you read that right, N1QL can do joins (on a single bucket or on several).
It works as long as the "foreign key" described by ON KEYS clause can be mapped to a document’s key in the joined bucket.
|
A specificity of N1QL that can be seen in the second statement is UNNEST
.
It extracts a sub-JSON and puts it at the same root level as the bucket (so its possible to do joins on each element in this sub-JSON as if they were entries in a left-hand side bucket).
For this final step, try to obtain the equivalent of these statements via the DSL and see how it guides you through the possibilities of the query language.
Indexing the Data: N1QL & GSI
Goals: Use the Index DSL to make sure data is indexed for N1QL to query it.
Index management is a bit more advanced (and is already done when loading the sample), so now that you’ve learned about N1QL, you can have a look at it. There is no code example in this application, but some samples are provided below for your reference.
For N1QL to work, you must first ensure that at least a Primary Index
has been created.
For that you can use the DSL from the Index
class:
q := gocb.NewN1qlQuery("CREATE PRIMARY INDEX ON `travel-sample`")
_, err := globalBucket.ExecuteN1qlQuery(q, nil)
You can also create secondary indexes on specific fields of the JSON, for better performance:
q := gocb.NewN1qlQuery("CREATE INDEX `def_username` ON `travel-sample`(username)")
_, err := globalBucket.ExecuteN1qlQuery(q, nil)
In this case, give a name to your index, specify the target bucket AND the field(s) in the JSON to index.
Full Text Search: Finding Hotels
Where: HotelSearch()
Goals: Use FTS to search for matching Hotels. Use sub-document API to fetch the relevant data for each hit.
Relevant Documentation Topics: Full Text Search (FTS) Using the Go SDK with Couchbase Server, Sub-Document Operations.
In this service, hotels are searched for using more fuzzy criterias, like the content of the address or the description of an hotel. This is done using Full Text Search (FTS). When some results match the specified criteria, only the relevant data for each result to be displayed in the UI is fetched using the subdocument API.
Let’s have a look at the HotelSearch()
method.
It accepts two parameters via HTTP, location
and description
, which are the two possible refining criteria for a hotel search.
qp := cbft.NewConjunctionQuery(cbft.NewTermQuery("hotel").Field("type"))
A ConjunctionQuery
allows you to combine multiple FTS queries into one, as an AND operation.
That search always includes an exact match criteria that restricts it to the hotel
data type (as reflected in the type
field of the JSON document).
If the user provided a location keyword, a second component is added to the FTS query that will look for that keyword in several address-related fields of the document.
This is done in an OR fashion, using a Disjunction
this time:
if location != "" && location != "*" { qp.And(cbft.NewDisjunctionQuery( cbft.NewMatchPhraseQuery(location).Field("country"), cbft.NewMatchPhraseQuery(location).Field("city"), cbft.NewMatchPhraseQuery(location).Field("state"), cbft.NewMatchPhraseQuery(location).Field("address"), )) }
Similarly, if a description keyword was provided by the user, the freeform text is inspected of the description
field and name
field of the document:
if description != "" && description != "*" {
qp.And(cbft.NewDisjunctionQuery(
cbft.NewMatchPhraseQuery(description).Field("description"),
cbft.NewMatchPhraseQuery(description).Field("name"),
))
}
The MatchPhraseQuery
can contain several words and will search for variations of the words (eg.
including plural forms or words with the same root...).
The compound FTS query is now ready to be executed.
A SearchQuery
object is built out of it, which also determines which FTS index to use ("hotel") and allows you to set various parameters (like a limit of maximum 100 hits to return).
The query is logged (and kept for narration) then executed, returning an SearchQueryResult
object:
q := gocb.NewSearchQuery("travel-search", qp).
Limit(100)
rows, err := globalBucket.ExecuteSearchQuery(q)
The FTS results are then iterated over, and the document corresponding to each result is fetched. In actuality, only the parts of the document that will be displayed in the UI are required. This is where the sub-document API comes in.
The sub-document API allows you to fetch or mutate only a set of paths inside a JSON document, without having to send the whole document back and forth. This can save network bandwidth if the document is large and the parts that the application is interested in are small. So here the results of the FTS search are iterated over and appropriate subdoc calls are triggered:
for _, hit := range rows.Hits() {
res, _ := globalBucket.LookupIn(hit.Id).
Get("country").
Get("city").
Get("state").
Get("address").
Get("name").
Get("description").
Execute()
// We ignore errors here since some hotels are missing various
// pieces of data, but every key exists since it came from FTS.
var hotel jsonHotel
res.Content("country", &hotel.Country)
res.Content("city", &hotel.City)
res.Content("state", &hotel.State)
res.Content("address", &hotel.Address)
res.Content("name", &hotel.Name)
res.Content("description", &hotel.Description)
respData.Data = append(respData.Data, hotel)
}
Each FTS result is represented as an SearchRowHit
which exposes the document’s Id
.
The sub-document API can then be used to fetch data (bucket.LookupIn(documentId)
) and specify what parts it wants: name, description, address, city, state and country.
The application then Execute()
the sub-document query.
In the rest of the code, the address-related fields are aggregated together and the data obtained is returned as a JSON object for use in the front-end.


Virat Kohli Inspires Tanuj Virwani For His Character In Inside Edge 2
Tanuj Virwani took diet inspirations from Virat Kohli to ace his look for Inside Edge 2
by IANSActor Tanuj Virwani, who is awaiting the launch of the second season of web show Inside Edge 2, has shared that he tried to follow Team India skipper Virat Kohli’s diet to get in shape for his character.
Virat, who is known to be a vegan recently said that he felt much better in life after turning vegetarian last year.
“Saw game-changers on Netflix. Being a vegetarian athlete has made me realize what I have believed all these years regarding diet was a myth. What an amazing documentary and yes I’ve never felt better in my life after I turned vegetarian,” Kohli had tweeted.
And it is this diet of Virat that has inspired Tanuj a lot.
“I wanted to get into a certain shape for the new season and after doing some research I managed to track down Kohli’s diet plan . Afterall, if you need inspiration to get into shape, you got to seek it from the best. It was really tough in the beginning but slowly and gradually I mentally conditioned myself into believing that if he can do it, so can I. Its all about mind over matter,” Tanuj, said.
Though Tanuj has not completely turned vegan, he has stopped eating red meat.
Apart from Inside Edge 2, Tanuj, who is the son of actress Rati Agnihotri, will also be seen in shows like Cartel and Code M.

'Absolutely bowfin!' Scotland confirm leaked kit as fans react with horror
The mood music around the national team makes it a challenging time to release a new strip.
by Jonathan McFarlaneThe SFA have confirmed that the Scotland strip leaked last week IS the genuine article.
They have announced on social media that the top, shorts and socks will be available from JD Sports from tomorrow morning.
Social media Pictures emerged on Wednesday of a display of shirts in a US shop with the tops priced at $90.
The major changes unveiled by kit manufacturer Adidas include blue shorts (rather than white), a new red and white sleeve trim and a sure to be polarising electricity style jagged pattern across the top.
Fans took to social media to register their thoughts and it's safe to say there were a few fans keen to stick the boot in.
@SMCDG81: Absolutely bowfin!
@gfpaterson: Those cuffs are horrendous. MAJOR mistake.
@wee_col: I won’t be buying that. Who decides these things???
@JMcConachie: Wow. That is awful. Those hospital ECG lines and that red stripe .. why .. why .. why ? Truly hideous !! 1 person in a million might think that looks nice. .. maybe
@greagsy: Worst home kit yet from @adidasfootball hopefully away kit may be better but going with history of away kits I doubt that. What is it with the Red and white sleeve?
Not everyone was so negative though, there were at least a few out there who backed Adidas' new design and will be wearing them on their next visit to Hampden .
@Coco_Fin: Lovely stuff
@Johnwcorcoran: Think I will need to be purchasing this
@historian_alex: Will be picking this up!

Singapore's bus routes
All bus stops and the routes that pass through them are visualized on the map.
Bus services can be a bi-directional service, a uni-directional service or a loop service. Bi-directional services will have routes in Direction 1 (RED) and 2 (BLUE), while uni-drectional and loop services will only have Direction 1 routes.
Note: The exact coordinates of path taken by each route is unknown. The smoothness of a route is dependent on the distance between bus stops. This explains the presence of straight lines that unrealistically cut across land in some routes.
I downloaded the shapefile of Singapore and converted it to geoJSON. D3 was then used to render the map of Singapore based on the provided vector geographical information.
var projection = d3.geoMercator().fitSize([width, height], geoJSON)
var path = d3.geoPath().projection(projection)
// DRAW MAP OF SINGAPORE
mapWrapper.selectAll(".country")
.data(geoJSON)
.enter()
.append("path")
.attr("class", "country")
.attr("d", path)
As there are over 20000 routes and 5000 bus stops to plot, i chose to render them with Canvas rather than SVG. Canvas prevents memory and performance issues in plotting large amount of elements. However, because I want to overlay the elements on top of the map (which is an SVG object), i had to create an embedded Canvas in the SVG map.


compound-railway-changelog
- RailwayJS History
require
, publish
method deprecated, use module.exports
insteadimport
and export
methods from controller scopecsrf_tag
to create the hidden input tag, thanks to fsateleras
option), now it affects helper names too, via fsatelerAllow to collect information about response handling, db queries, etc.. Now we can build our own newrelic, with blackjack and hookers!
Updated generators, helpers and ejs-ext module. Many thanks to Garret Johnson
Extend helpers API prototype object:
railway.helpers.HelperSet.prototype.myCoolHelper = function () {
return '
Application-wide helper
'; // use this in your plugins
};
to get <%- myCoolHelper %>
availabe in every view
Generate your application with --stylus
option to work with stylus out-of-box:
/app/assets/styles/*.styl
GET /styles/*.css
app.set 'view options', layout : false
Important change! Now resourceful form helpers generates input names within csope:
form_for(post, function (f)
f.input('title')
});
Will generate <input name="Post[title]" />
instead of <input name="title" />
For all existing code this behavior is not turned on to not break anything,
but for newly generated apps it turned on in config/environment
file
app.set 'view options', complexNames: true
CRUD generator also rewritten to match new structure
Major amends:
memory
Minor improvements:
Bugfixes:
rw s
A lot of changes in core, fully rewritten controllers flow, node 0.6.0 compatible
Migration notes:
publish
method, not export
(not allowed in node 0.6.0).db/schema
[issue #63]New features:
ensure mongo and redis servers are running, then run
nodeunit test/generators.coffee
or
npm test
Check out autogenerated tests for controllers, additional nodeunit stubs can be used:
test.redirect '/path'
test.render 'viewName'
test.send 'what'
test.success() # check status 200
test.assign 'memberName'
More stubs coming soon
Now form labels can be localized automatically, just use it as previously:
<% form_for(user, {}, function (form) { %>
<%- form.label('name') %>
<% }); %>
And add translation to locales/en.yml
:
en:
models:
User:
fields:
name: User name
email: Email address
Application can be generated with --tpl
key, for now possibly values are
This list can be extended. Check out packages npm ejs-ext
and jade-ext
if you need to learn how to do it. It easy: just add another lang-ext
package
and install it before running railway g app --tpl lang
sudo npm link
after railway init
)Small improvements:
log/ENV.log
Observer is a kind of controller, that listen for some event in the system, for example: paypal, twitter or facebook observers listens for callback from foreign service. Email observer may listen some events related to emails.
If you need app.on('someEvent') you should place this code in
APPROOT/app/observers/NAME_observer.js
Just place your key and cert into config directory, railway will use it.
Default names for keys are tsl.key
and tsl.cert
, but you can store in in another place, in that case just pass filenames to createServer function:
server.js
require('railway').createServer({key: '/tmp/key.pem', cert: '/tmp/cert.pem'});
config/locales/*.yml
app.disable('model cache');
and app.disable('eval cache');
Scaffold generator railway generate scaffold ModelName field1:type1 field2:type2
It generates model, crud controller and appropriated views
Now you can run railway init blog
and railway will create directory structure
within blog
root folder
By default will created file config/database.json
that will force you to use
mongoose driver, feel free to modify it and use redis or mysql (both supported)
Also, running express -t ejs
no longer required
Mongoose driver support
Describe your schema in db/schema.js
, it's just commonjs module which should export
models. For describing logic please use app/models/*.js
files. Every model
described in schema accessible as global object in all models and controllers.
Added features generator for cucumis
. Run railway generate features
, then
you will be able to create features
using Gherkin language, parsed by kyuri.

Pattern Matching with case let
Today we will talk about Pattern Matching, one of my favorite features in Swift. Pattern Matching is the act of checking a given sequence of tokens for the presence of the constituents of some pattern. Swift has a particular keyword for applying Pattern Matching: case let. Let’s dive into examples.
Enums
Pattern Matching is very useful while working with enums. As a part of “Maintaining State in Your ViewControllers” post, we talk about State enum, which describes the state of ViewController. Let’s see how we can efficiently use Pattern Matching with it.

enum State<Data> {
case loading
case loaded(Data)
case failed(Error)
}
switch state {
case .loading: renderLoading()
case let .loaded(shows) where shows.isEmpty: renderEmptyView()
case let .loaded(shows): render(shows)
case let .failed(error): render(error)
}
While regular switching on enum with associated values we can also use case let keyword to match it to some pattern and assign associated value to a variable. Another beautiful option here is filtering associated value by using where keyword.
Optionals
Optional in Swift is the enum with two cases, so you can apply Pattern Matching as we do it before with enums. But in the case of optionals, we have some additional features. Let’s check the example code.
1

let value: Int? = 10
switch value {
case let value? where value > 10: print("higher than ten")
case let .some(value): print(value)
case .none: print("none")
}
value? here means the non-nil value of optional. So, it is the same as .some(value).
Tuples
Another good use case for Pattern Matching can be tuples. Tuples often used as lightweight types for grouping some data. Let’s see how we can use Pattern Matching on a tuple which presents authentication data.
1
2

5

7
let auth = (username: "majid", password: "veryStrongPassword")
switch auth {
case ("admin", "admin"): renderAdmin()
case let (_, password) where password.count < 6: renderShortPasswordMessage()
case let (username, password): renderUserProfile(username, password)
}
As you can see, we can apply to tuples all the matching features which we used with enums. We can also match the particular value to the tuple as we do for matching admin data.
case let with flow statements
I want to mention that you can easily use case let keyword with any flow control statement, let’s see how we can use it with if condition statements.
1
2
3
if case let .loaded(shows) = state, shows.isEmpty {
renderEmptyView()
}
Same is possible with guard statement.
1
2
3
guard case let .loaded(shows) = state, shows.isEmpty else {
// Do something here
}
Another compelling case let usage is possible with for-in loops, we can easily filter items.
1
2
3
4
let stateHistory: [State<[Show]>] = [.loaded([]), .loading]
for case let .loaded(shows) in stateHistory where shows.count > 2 {
// Do something here
}
Conclusion
Today we discussed how powerful can be Pattern Matching in Swift, and how we can use it in daily development.

Hospital launches “No Safe Vape” campaign
LEBANON, N.H. (AP) - Dartmouth-Hitchcock Health has launched a new education campaign in New Hampshire and Vermont about the dangers of vaping.
The “No Safe Vape” effort includes a website that presents facts about vaping and a list of local, regional and national resources for those seeking further information or help quitting. An advertising campaign is planned, and the health system also hosted a Facebook Live event with experts and teens. Dr. Susanne Tanski, a Dartmouth-Hitchcock pediatrician, also briefed members of the U.S. Senate last week about the hazards of vaping.
As electronic cigarette use by teenagers has surged, health advocates are encouraging President Donald Trump to move forward with a federal ban on thousands of flavors used in vaping products.

10 superfoods to improve fertility levels
One should certainly inculcate the habit of going for regular workouts and consume a balanced diet. A healthy body shall fundamentally help in speeding up the process of conceiving.
By Dr Rita Bakshi
Infertility is a problem that has been disturbing numerous lives of modern couples. It has been considerably growing over the last few years also because of inactive lifestyle choices and unhealthy habits.
One of the very significant factors that disrupt the whole process of fertility is lifestyle or consistent unhealthy practices that a person embarks on in their daily life. While one faces reproductive problems, it is a mandate to keep a track on their lifestyle and ensure that it is healthy. One should certainly inculcate the habit of going for regular workouts and consume a balanced diet. A healthy body shall fundamentally help in speeding up the process of conceiving.
Here are some superfoods that one must accommodate in their diets to boost fertility levels:
1. Nuts and dry fruits
Dried fruits and nuts are a great source of protein, vitamins and minerals. Nuts have high quantities of selenium, a mineral that declines chromosomal damage in eggs. This shall definitely help in boosting fertility levels as the damage shall be reduced due to the presence of selenium. This antioxidant keeps away free radicals and enhances egg production in the human body.
2. Green leafy vegetables
The green leafy vegetables are a rich source of folic acid and vitamin C, which helps in improving the process of ovulation. It decreases the chances of miscarriage and genetic abnormalities. Vegetables like spinach, broccoli, kale and fenugreek must be included in the diet for greater results. Incidentally, the benefits instilled in green vegetables also help in making good quality of sperms.
3. Garlic
Garlic is a fertility boosting spice and is augmented by the presence of an antioxidant, selenium. Garlic also maintains the estrogen balance in the body and thus supports fertility. For men, it really helps in enhancing the sperm movement which increases the odds of conception when consumed regularly.
4. Dairy products
The dairy products are generally rich in calcium, good fats and vitamin D. These products are essential for improving fertility levels in couples who want to conceive faster. They nourish the body wholly and help in conceiving faster. Greek yogurt, butter and whole milk are important to consume.
5. Berries
Berries are actually excellent for both men and women who are trying to conceive. Raspberries and blueberries are rich in natural antioxidants and anti-inflammatory phytonutrients, which help in boosting fertility levels. They are also a good source of folate and vitamin C, which can help with foetal development. Berries also help in weight loss and should essentially be incorporated in your fertility boosting diet.
6. Beans
Beans are packed with lean protein and iron. It is very essential to consume beans while you are trying to conceive as low levels of iron in the body leads to the production of less healthy eggs. Beans are recognised to escalate a woman’s fertility levels and even boost libido.
7. Pumpkin seeds
Pumpkin seeds really help in producing matured cells. They are also a rich source of zinc that aids in increasing testosterone and semen levels. It also stimulates a proper flow of blood to all the reproductive organs that sustains and controls a strong reproductive system. Pumpkin seeds are power packed with numerous benefits and the presence of abundant nutrition, thus must be consumed by one and all.
8. Bananas
Bananas are jam-packed with Vitamin B6 and help in the formation of a zygote by regulating the hormones involved in the ovulation process. It is also a rich source with potassium and Vitamin C as well. The inadequacy of potassium and vitamin B6 results in poor quality of eggs and sperms. Therefore, it is important for the intending parents to include bananas in breakfast.
9. Eggs
As we all know, eggs are a very good source of vitamins which are imperative to boost fertility levels. The presence of Omega 3 is also a source that improves the level of fertility and choline reduces the risk of some birth defects. Always try and amalgamate eggs in your breakfast.
10. Quinoa
It is vital that at least 50 percent of the daily grain intake to the prospective mother comes from whole grains. Swapping animal-based proteins for plant-based ones like quinoa helps in augmenting the chances of conception. Also, this helps in stabilising blood sugar levels and even regulates the menstrual cycle. Quinoa is a rich source of fibre too.

PLScenes (Planet Labs Scenes), Data V1 API
GDAL/OGR >= 2.2
The driver supports read-only operations to list scenes and their metadata
as a vector layer per item-types:
"PSOrthoTile", "REOrthoTile", "PSScene3Band", "PSScene4Band", "REScene", "Landsat8L1G", "Sentinel2L1C".
It can also access raster scenes.
Dataset name syntax
The minimal syntax to open a datasource is : PLScenes:[options]
Additional optional parameters can be specified after the ':' sign.
Currently the following one is supported :
- version=data_v1: To specify the API version to request.
- api_key=value: To specify the Planet API KEY. It is mandatory, unless
it is supplied through the open option API_KEY, or the configuration option PL_API_KEY.
- follow_links=YES/NO: Whether assets links should be followed for each scene (vector).
Getting assets links require a HTTP request per scene, which might be costly when
enumerating through a lot of products. Defaults to NO.
- scene=scene_id: To specify the scene ID, when accessing raster data.
Optional for vector layer access.
- itemtypes=name: To specify the item types name.
Optional for vector layer access. Mandatory for raster accessI.
- asset=value: To specify the asset type
(for raster fetching). Default is "visual". Optional for vector layer access.
If the option is not specified and the 'visual' asset category does not exist for the scene
(or if the value is set to 'list'), the returned dataset will have subdatasets
for the available asset categories.
- medata=YES/NO: (Raster only) Whether scene metadata should be
fetch from the API and attached to the raster dataset. Defaults to YES.
If several parameters are specified, they must be separated by a comma.
Open options
The following open options are available :
- VERSION=data_v1: To specify the API version to request.
- API_KEY=value: To specify the Planet API KEY.
- FOLLOW_LINKS=YES/NO: Whether assets links should be followed for each scene (vector).
Getting assets links require a HTTP request per scene, which might be costly when
enumerating through a lot of products. Defaults to NO.
- SCENE=scene_id: To specify the scene ID, when accessing raster data.
Optional for vector layer access.
- ITEMTYPES=name: To specify the item types name.
Optional for vector layer access. Mandatory for raster access.
- ASSET=value: To specify the asset type
(for raster fetching). Default is "visual". Optional for vector layer access.
If the option is not specified and the 'visual' asset category does not exist for the scene
(or if the value is set to 'list'), the returned dataset will have subdatasets
for the available asset categories.
- RANDOM_ACCESS=YES/NO: Whether raster should be accessed in random access mode
(but with potentially not optimal throughput). If NO, in-memory ingestion is done.
Default is YES.
- ACTIVATION_TIMEOUT=int: Number of seconds during which to wait for
asset activation (raster). Default is 3600.
- METADATA=YES/NO: (Raster only) Whether scene metadata should be
fetched from the API and attached to the raster dataset. Defaults to YES.
Configuration options
The following configuration options are available :
- PL_API_KEY=value: To specify the Planet API KEY.
Attributes
The layer field definition is built from the "plscensconf.json"
file in the GDAL configuration. The links to downloadable products are
in asset_XXXXX_location attributes where XXXXX is the asset category id,
when they are active. Otherwise they should be activated by sending a POST request to
the URL in the asset_XXXXX_activate_link attribute (what the raster driver
does automatically)
Geometry
The footprint of each scene is reported as a MultiPolygon with a longitude/latitude
WGS84 coordinate system (EPSG:4326).
Filtering
The driver will forward any spatial filter set with SetSpatialFilter() to
the server. It also makes the same for simple attribute filters set with
SetAttributeFilter(). Note that not all attributes support all comparison
operators. Refer to comparator column in Metadata properties
Paging
Features are retrieved from the server by chunks of 250 by default (and this
is the maximum value accepted by the server).
This number can be altered with the PLSCENES_PAGE_SIZE
configuration option.
Vector layer (scene metadata) examples
Listing all scenes available (with the rights of the account) :
ogrinfo -ro -al "PLScenes:" -oo API_KEY=some_value
or
ogrinfo -ro -al "PLScenes:api_key=some_value"
or
ogrinfo -ro -al "PLScenes:" --config PL_API_KEY some_value
Listing all scenes available on PSOrthoTile item types, under a point of (lat,lon)=(40,-100) :
ogrinfo -ro -al "PLScenes:" -oo API_KEY=some_value PSOrthoTile -spat -100 40 -100 40
Listing all scenes available within a bounding box (lat,lon)=(40,-100) to (lat,lon)=(39,-99)
ogrinfo -ro -al "PLScenes:" -oo API_KEY=some_value -spat -100 40 -99 39
Listing all scenes available matching criteria :
ogrinfo -ro -al "PLScenes:" -oo API_KEY=some_value PSOrthoTile -where "acquired >= '2015/03/26 00:00:00' AND cloud_cover < 10"
List all downloadable scenes:
ogrinfo -ro -al -q "PLScenes:" -oo API_KEY=some_value PSOrthoTile -where "permissions='assets:download'"
Raster access
Scenes can be accessed as raster datasets, provided
that the scene ID is specified with the 'scene' parameter / SCENE open option.
The 'itemtypes' parameter / ITEMTYPES open option must also be specified.
The asset type (visual, analytic, ...) can be specified with the
'asset' parameter / ASSET open option. The scene id is the
content of the value of the 'id' field of the features.
If the product is not
already generated on the server, it will be activated, and the driver will wait
for it to be available. The length of this retry can be configured with the
ACTIVATION_TIMEOUT open option.
Raster access examples
Displaying raster metadata :
gdalinfo "PLScenes:scene=scene_id,itemtypes=itemypes,asset=analytic" -oo API_KEY=some_value
or
gdalinfo "PLScenes:" -oo API_KEY=some_value -oo ITEMTYPES=itemtypes -oo SCENE=scene_id -oo ASSET=analytic
Converting/downloading a whole file:
gdal_translate "PLScenes:" -oo API_KEY=some_value -oo SCENE=scene_id \
-oo ITEMTYPES=itemtypes -oo ASSET=analytic -oo RANDOM_ACCESS=NO out.tif
