Express 4 is a breaking change from Express 3. That means an existing Express 3 app will not work if you update the Express version in its dependencies.
This article covers:
There are several significant changes in Express 4:
See also:
Express 4 no longer depends on Connect, and removes all built-in
middleware from its core, except for the
express.static
function. This means that Express is now an
independent routing and middleware web framework, and Express versioning
and releases are not affected by middleware updates.
Without built-in middleware, you must explicitly add all the middleware that is required to run your app. Simply follow these steps:
npm install --save <module-name>
require('module-name')
app.use( ... )
The following table lists Express 3 middleware and their counterparts in Express 4.

Here is the complete list of Express 4 middleware.
In most cases, you can simply replace the old version 3 middleware with its Express 4 counterpart. For details, see the module documentation in GitHub.
app.use
accepts parametersIn version 4 you can use a variable parameter to define the path where middleware functions are loaded, then read the value of the parameter from the route handler. For example:
Apps now implicitly load routing middleware, so you no longer have to
worry about the order in which middleware is loaded with respect to the
router
middleware.
The way you define routes is unchanged, but the routing system has two new features to help organize your routes:
{: .doclist } * A new method, app.route()
, to create
chainable route handlers for a route path. * A new class,
express.Router
, to create modular mountable route handlers.
app.route()
method
The new app.route()
method enables you to create chainable
route handlers for a route path. Because the path is specified in a single
location, creating modular routes is helpful, as is reducing redundancy
and typos. For more information about routes, see
Router()
documentation.
Here is an example of chained route handlers that are defined by using the
app.route()
function.
app.route('/book')
.get(function (req, res) {
res.send('Get a random book')
})
.post(function (req, res) {
res.send('Add a book')
})
.put(function (req, res) {
res.send('Update the book')
})
express.Router
class
The other feature that helps to organize routes is a new class,
express.Router
, that you can use to create modular mountable
route handlers. A Router
instance is a complete middleware
and routing system; for this reason it is often referred to as a
“mini-app”.
The following example creates a router as a module, loads middleware in it, defines some routes, and mounts it on a path on the main app.
For example, create a router file named birds.js
in the app
directory, with the following content:
var express = require('express')
var router = express.Router()
// middleware specific to this router
router.use(function timeLog (req, res, next) {
console.log('Time: ', Date.now())
next()
})
// define the home page route
router.get('/', function (req, res) {
res.send('Birds home page')
})
// define the about route
router.get('/about', function (req, res) {
res.send('About birds')
})
module.exports = router
Then, load the router module in the app:
The app will now be able to handle requests to the /birds
and
/birds/about
paths, and will call the
timeLog
middleware that is specific to the route.
The following table lists other small but important changes in Express 4:
| Object | Description |
|---|---|
| Node.js | Express 4 requires Node.js 0.10.x or later and has dropped support for Node.js 0.8.x. |
http.createServer()
|
The http module is no longer needed, unless you need to
directly work with it (socket.io/SPDY/HTTPS). The app can be started
by using the app.listen() function.
|
app.configure()
|
The app.configure() function has been removed. Use the
process.env.NODE_ENV or
app.get('env') function to detect the environment and
configure the app accordingly.
|
json spaces
|
The json spaces application property is disabled by
default in Express 4.
|
req.accepted()
|
Use req.accepts() , req.acceptsEncodings() ,
req.acceptsCharsets() , and
req.acceptsLanguages() .
|
res.location()
|
No longer resolves relative URLs. |
req.params
|
Was an array; now an object. |
res.locals
|
Was a function; now an object. |
res.headerSent
|
Changed to res.headersSent . |
app.route
|
Now available as app.mountpath . |
res.on('header')
|
Removed. |
res.charset
|
Removed. |
res.setHeader('Set-Cookie', val)
|
Functionality is now limited to setting the basic cookie value. Use
res.cookie() for added functionality.
|
Here is an example of migrating an Express 3 application to Express 4. The
files of interest are app.js
and package.json
.
app.js
Consider an Express v.3 application with the following
app.js
file:
var express = require('express')
var routes = require('./routes')
var user = require('./routes/user')
var http = require('http')
var path = require('path')
var app = express()
// all environments
app.set('port', process.env.PORT || 3000)
app.set('views', path.join(__dirname, 'views'))
app.set('view engine', 'pug')
app.use(express.favicon())
app.use(express.logger('dev'))
app.use(express.methodOverride())
app.use(express.session({ secret: 'your secret here' }))
app.use(express.bodyParser())
app.use(app.router)
app.use(express.static(path.join(__dirname, 'public')))
// development only
if (app.get('env') === 'development') {
app.use(express.errorHandler())
}
app.get('/', routes.index)
app.get('/users', user.list)
http.createServer(app).listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'))
})
package.json
The accompanying version 3 package.json
file might look
something like this:
{
"name": "application-name",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node app.js"
},
"dependencies": {
"express": "3.12.0",
"pug": "*"
}
}
Begin the migration process by installing the required middleware for the Express 4 app and updating Express and Pug to their respective latest version with the following command:
Make the following changes to app.js
:
The built-in Express middleware functions
express.favicon
, express.logger
,
express.methodOverride
, express.session
,
express.bodyParser
and
express.errorHandler
are no longer available on the
express
object. You must install their alternatives
manually and load them in the app.
You no longer need to load the app.router
function. It is
not a valid Express 4 app object, so remove the
app.use(app.router);
code.
Make sure that the middleware functions are loaded in the correct
order - load errorHandler
after loading the app routes.
package.json
Running the above npm
command will update
package.json
as follows:
{
"name": "application-name",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node app.js"
},
"dependencies": {
"body-parser": "^1.5.2",
"errorhandler": "^1.1.1",
"express": "^4.8.0",
"express-session": "^1.7.2",
"pug": "^2.0.0",
"method-override": "^2.1.2",
"morgan": "^1.2.2",
"multer": "^0.1.3",
"serve-favicon": "^2.0.1"
}
}
app.js
Then, remove invalid code, load the required middleware, and make other
changes as necessary. The app.js
file will look like this:
var http = require('http')
var express = require('express')
var routes = require('./routes')
var user = require('./routes/user')
var path = require('path')
var favicon = require('serve-favicon')
var logger = require('morgan')
var methodOverride = require('method-override')
var session = require('express-session')
var bodyParser = require('body-parser')
var multer = require('multer')
var errorHandler = require('errorhandler')
var app = express()
// all environments
app.set('port', process.env.PORT || 3000)
app.set('views', path.join(__dirname, 'views'))
app.set('view engine', 'pug')
app.use(favicon(path.join(__dirname, '/public/favicon.ico')))
app.use(logger('dev'))
app.use(methodOverride())
app.use(session({
resave: true,
saveUninitialized: true,
secret: 'uwotm8'
}))
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))
app.use(multer())
app.use(express.static(path.join(__dirname, 'public')))
app.get('/', routes.index)
app.get('/users', user.list)
// error handling middleware should be loaded after the loading the routes
if (app.get('env') === 'development') {
app.use(errorHandler())
}
var server = http.createServer(app)
server.listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'))
})
Unless you need to work directly with the http
module
(socket.io/SPDY/HTTPS), loading it is not required, and the app can be
simply started this way:
The migration process is complete, and the app is now an Express 4 app. To confirm, start the app by using the following command:
Load http://localhost:3000 and see the home page being rendered by Express 4.
The command-line tool to generate an Express app is still
express
, but to upgrade to the new version, you must
uninstall the Express 3 app generator and then install the new
express-generator
.
If you already have the Express 3 app generator installed on your system, you must uninstall it:
Depending on how your file and directory privileges are configured, you
might need to run this command with sudo
.
Now install the new generator:
Depending on how your file and directory privileges are configured, you
might need to run this command with sudo
.
Now the express
command on your system is updated to the
Express 4 generator.
Command options and use largely remain the same, with the following exceptions:
{: .doclist } * Removed the --sessions
option. * Removed the
--jshtml
option. * Added the --hogan
option to
support Hogan.js.
Execute the following command to create an Express 4 app:
If you look at the contents of the app4/app.js
file, you will
notice that all the middleware functions (except
express.static
) that are required for the app are loaded as
independent modules, and the router
middleware is no longer
explicitly loaded in the app.
You will also notice that the app.js
file is now a Node.js
module, in contrast to the standalone app that was generated by the old
generator.
After installing the dependencies, start the app by using the following command:
If you look at the npm start script in the package.json
file,
you will notice that the actual command that starts the app is
node ./bin/www
, which used to be node app.js
in
Express 3.
Because the app.js
file that was generated by the Express 4
generator is now a Node.js module, it can no longer be started
independently as an app (unless you modify the code). The module must be
loaded in a Node.js file and started via the Node.js file. The Node.js
file is ./bin/www
in this case.
Neither the bin
directory nor the extensionless
www
file is mandatory for creating an Express app or starting
the app. They are just suggestions made by the generator, so feel free to
modify them to suit your needs.
To get rid of the www
directory and keep things the “Express
3 way”, delete the line that says module.exports = app;
at
the end of the app.js
file, then paste the following code in
its place:
app.set('port', process.env.PORT || 3000)
var server = app.listen(app.get('port'), function () {
debug('Express server listening on port ' + server.address().port)
})
Ensure that you load the debug
module at the top of the
app.js
file by using the following code:
Next, change "start": "node ./bin/www"
in the
package.json
file to "start": "node app.js"
.
You have now moved the functionality of ./bin/www
back to
app.js
. This change is not recommended, but the exercise
helps you to understand how the ./bin/www
file works, and why
the app.js
file no longer starts on its own.


Production Implementation Requirements
In order to provide a production quality integration with Zip the application developer must undertake a number of steps.
Power Failure/Crash Recovery
A reliable integration must handle situation where the POS process dies while a Zip order (or refund) is pending, due to a power/hardware failure, OS restart, bug etc. In this case the usual pattern is: * On start-up, or another suitable event, check a persistent store for a list of outstanding requests. For each pending request, recover at least the MerchantReference, and preferably the order id (if it was received and persisted from the initial CreateOrder request). * If you are only able to retrieve the merchant reference, retry the order create request ensuring 'duplicate checking' is enabled. This will allow you to retrieve the Zip order id required in the following steps without risk of double charging the customer. * If a pending order is found, begin polling for the status of that order. If the order is still pending after the first check either continue polling or cancel immediately. When a final state is reached the POS should relate this answer back to the pending POS transaction, provide some way for the user to apply it to a new transaction or perform an automatic refund depending on how the POS is designed. * If a pending refund is found, retry the refund request using the same merchant reference if you want to ensure the refund occurred. Zip refunds requests are idempotent, and sending the same request again will only result in at most one refund being applied. * Before sending a CreateOrderRequest or RefundOrderRequest, generate a unique MerchantReference to be used on that request and save it to persistent storage so it can be used for crash recovery (see above). For a CreateOrderRequest also store the order id returned as soon as possible if the call is successful. * When a POS transaction is completed (or next persisted to permanent storage) with an order or refund that has reached a final status, remove that requests reference from the persistent store of pending requests so it will no longer be rechecked on a restart (see previous steps).
Error Handling
All methods in the ZipClient class might throw exceptions. Some exceptions such as System.ArgumentException and System.ArgumentNullException occur before the request is sent, if the request data doesn't meet the minimum known requirements for Zip. These should be handled probably presented to the user to tell them what is missing.
In addition, any error normally thrown by the .Net HttpClient class including System.TaskCanceledException and HttpRequestException could be re-thrown from these methods. TaskCanceled and timeout exceptions may require special handling. For example if these exceptions are thrown during a CreateOrderRequest call and the POS is not going to try again then another call should be made to CancelOrder to ensure the order is not subsequently accepted by the user.
HttpResponseExceptions may indicate a transient error, such as the network being briefly down, or a service unavailable/too many requests response from the server. In this case the POS should wait a short period and then retry the operation.
Any error returned by the Zip API (indicating the HTTP call was received by the server but resulted in an error) is converted to a ZipApiException, with an Errors property that contains details of the error response.
Polling Timeout
It's possible that due to a long network outage or similar problem that a create order request may never reach an approved or declined state and cannot be immediately cancelled. In this case the POS should have a timeout where it gives up polling. This timeout should not be too short, or should prompt the operator to ask if it should give up, as new customers can sometimes take several minutes to complete the sign up process. It is up to the POS to decide how to behave, but the usual logic is:
- Treat the request as declined
- Store the request somewhere to be rechecked at a later time when the network is available again.
- If the customer still wants to make payment they will have to choose another payment method (since the network is not available and Zip cannot be used)
- On recheck (once the network is available again):
- If the payment is pending, cancel it.
- If the payment is approved, refund it.
- If the payment is cancelled or declined, there is nothing to do except remove it from the list of rechecks
Manual Cancellation
It is possible the POS operator may need to cancel an in-progress payment, if the end consumer is unable to do so for some reason. It's also possible the customer's device may run out of battery, have no network connection to receive the payment request, or get dropped and damaged etc. In any of these cases where the payment cannot be processed for a known reason the POS user should have the option to manually cancel the request without waiting for a long timeout. This needs to use the CancelOrder method of the ZipClient object to notify Zip of the cancellation, and only treat the payment as cancelled if the cancellation request is successful.
Cancelling Orders
When making a CancelOrder request an exception might be thrown, and this could be caused by the order having been approved or declined between when you last performed a status check and when the cancellation request was received. If an ZipApiException is thrown as the result of a cancellation request your code should re-check the current status of the order and take action depending on the latest status.

Posted on January 29, 2017
The Second Blog Post!
What did you do this past week?
So far, we've discussed a few further optimizations to the collatz hackerrank problem and the precise workflow for projects in this class (Detailing the full process of Travis CI, github, the skeleton code we've been given, and the final process for putting it up on hackerranck and Canvas). Pretty much all of my lab time this week was spent setting up this workflow, which was a nightmare due to some mistakes on my part and then some technology glitches.
What's in the way?
With all of the technology tools set up, the only remaining part of the lab is the actual coding and the setting up of the testing. I actually anticipate this will take a bit less time, as I've got a pretty good idea for an algorithm, and I had a terrible time with Travis CI.
What will you do next week?
I'll be spending a lot of time in the lab. I still plan to get this done a few days early, so I'm trying to push this work forward in the week. I'll also likely attend the lab proctor session on tuesday. I've also procrastinated on the reading in order to make up for my early work on the lab, so I'll be doing that before class on Monday.
What's my experience in the class?
So far, the quizzes have been fair and the reading has made sense. The technology tools have been a huge pain, but that's mostly my fault. With more looking and less leaping, there would have been way less angry confusion on my part. With a defined direction and an understanding of the steps it would have taken you way less time. The programming seems straightforward now that I can actually do it.
What's the tip of the week?
Holy heck read the instructions. The instructions, and the instructions for each tech tool you use. With an actual understanding of the steps and more attention to detail I would be done with this lab already. I've already wasted hours because I thought I was too cool to prepare. Be smarter then me.

If we want to use the popular messaging system Kafka with our Elixir projects, we have a few wrappers we can choose from. This blogpost covers integrating one of them, Kaffe, which doesn’t have a lot of resources and therefore can be tricky to troubleshoot.
In this codealong we’ll build a simple Elixir application and use Kaffe to connect it to a locally running Kafka server. Later we’ll cover a couple of variations to connect a dockerized Kafka server or an umbrella Elixir app.
This post assumes basic knowledge of Elixir and no knowledge of Kafka or Kaffe. Here is the repo with the full project: Elixir Kaffe Codealong.
What is Kafka, briefly?
Kafka is a messaging system. It does essentially three things:
- Receives messages from applications
- Keeps those messages in the order they were received in
- Allows other applications to read those messages in order
A use case for Kafka: Say we want to keep an activity log for users. Every time a user triggers an event on your website - logs in, makes a search, clicks a banner, etc. - you want to log that activity. You also want to allow multiple services to access this activity log, such as a marketing tracker, user data aggregator, and of course your website’s front-end application. Rather than persisting each activity to your own database, we can send them to Kafka and allow all these applications to read only what they need from it.
Here’s a basic idea of how this might look:
The three services reading from Kafka would only take the pieces of data that they require. For example, the first service would only read from the banner_click
topic while the last only from search_term
. The second service that cares about active users might read from both topics to capture all site activity.
Basic Kafka terminology
Before we jump into the codealong let’s clarify a few common Kafka terms you’ll run into as you’re learning more about this service:
- consumer: what is receiving messages from Kafka
- producer: what is sending messages to Kafka
- topic: a way to organize messages and allow consumers to only subscribe to the ones they want to receive
- partition: allows a topic to be split among multiple machines and retain the same data so that more than one consumer can read from a single topic at a time
- leader/replica: these are types of partitions. There is one leader and multiple replicas. The leader makes sure the replicas have the same and newest data. If the leader fails, a replica will take over as leader.
- offset: the unique identifier of a message that keeps its order within Kafka
Codealong: basic Elixir app & Kafka running locally
Set up Kafka Server
Follow the first two steps of the quickstart instructions from Apache Kafka:
- Download the code
- Start the servers
Zookeeper (a service that handles some coordination and state management for Kafka)
bin/zookeeper-server-start.sh config/zookeeper.properties
Kafkabin/kafka-server-start.sh config/server.properties
Set up Elixir App
-
1. Start new project
mix new elixir_kaffe_codealong
- 2. Configure kaffe
- 2.a: In
mix.exs
add:kaffe
to the list of extra applications:def application do [ extra_applications: [:logger, :kaffe] ] end
- 2.b: Add kaffe to list of dependencies:
defp deps do [ {:kaffe, "~> 1.9"} ] end
-
2.c: Run
mix deps.get
in the terminal to lock new dependencies. - 3. Configure producer
in
config/config.exs
add:config :kaffe, producer: [ endpoints: [localhost: 9092], # endpoints references [hostname: port]. Kafka is configured to run on port 9092. # In this example, the hostname is localhost because we've started the Kafka server # straight from our machine. However, if the server is dockerized, the hostname will # be called whatever is specified by that container (usually "kafka") topics: ["our_topic", "another_topic"], # add a list of topics you plan to produce messages to ]
-
4. Configure consumer
- 4.a: add
/lib/application.ex
with the following code:defmodule ElixirKaffeCodealong.Application do use Application # read more about Elixir's Application module here: https://hexdocs.pm/elixir/Application.html def start(_type, args) do import Supervisor.Spec children = [ worker(Kaffe.Consumer, []) # calls to start Kaffe's Consumer module ] opts = [strategy: :one_for_one, name: ExampleConsumer.Supervisor] Supervisor.start_link(children, opts) end end
- 4.b: back in
mix.exs
, add a new item to the application function:def application do [ extra_applications: [:logger, :kaffe], mod: {ElixirKaffeCodealong.Application, []} # now that we're using the Application module, this is where we'll tell it to start. # We use the keyword `mod` with applications that start a supervision tree, # which we configured when adding our Kaffe.Consumer to Application above. ] end
- 4.c: add a consumer module to accept messages from Kafka as
/lib/example_consumer.ex
with the following code:defmodule ExampleConsumer do # function to accept Kafka messaged MUST be named "handle_message" # MUST accept arguments structured as shown here # MUST return :ok # Can do anything else within the function with the incoming message def handle_message(%{key: key, value: value} = message) do IO.inspect(message) IO.puts("#{key}: #{value}") :ok end end
- 4.d: configure the consumer module in
/config/config.exs
config :kaffe, consumer: [ endpoints: [localhost: 9092], topics: ["our_topic", "another_topic"], # the topic(s) that will be consumed consumer_group: "example-consumer-group", # the consumer group for tracking offsets in Kafka message_handler: ExampleConsumer, # the module that will process messages ]
- 5. Add a producer module (optional, can also call Kaffe from the console)
We’re going to wrap the functions Kaffe provides us in our own methods for ExampleProducer. Calling on Kaffe directly would also work; the
produce_sync
function is what ultimately sends our message to Kafka.
add /lib/example_producer.ex
with the following code:
defmodule ExampleProducer do
def send_my_message({key, value}, topic) do
Kaffe.Producer.produce_sync(topic, [{key, value}])
end
def send_my_message(key, value) do
Kaffe.Producer.produce_sync(key, value)
end
def send_my_message(value) do
Kaffe.Producer.produce_sync("sample_key", value)
end
end
- 6. Send and receive messages in the console!
Now we have everything configured and can use the modules we’ve created to send and read messages through Kafka!
- We’re going to call on our producer to send a message to the Kafka server.
- The Kafka server receives the message.
- Our consumer, which we configured to subscribe to the topic called “another_topic”, will receive the message we’ve sent and print it to the console.
Start an interactive elixir shell with iex -S mix
and call the following:
iex> ExampleProducer.send_my_message({"Metamorphosis", "Franz Kafka"}, "another_topic")
...>[debug] event#produce_list topic=another_topic
...>[debug] event#produce_list_to_topic topic=another_topic partition=0
...>:ok
iex> %{
...> attributes: 0,
...> crc:<PHONE_NUMBER>, # will vary
...> key: "Metamorphosis",
...> magic_byte: 1,
...> offset: 1, # will vary
...> partition: 0,
...> topic: "another_topic",
...> ts:<PHONE_NUMBER>702, # will vary
...> ts_type: :create,
...> value: "Franz Kafka"
...> }
...> Metamorphosis: Franz Kafka
Variations: Docker & Umbrella Apps
- If you’re running Kafka from a docker container (most common in real applications), you will use that hostname in the config file rather than
localhost
- In an umbrella app you’ll configure Kaffe in the child application running it. If you have apps separated by environment, you can start the consumer by structuring it as a child like this:
children = case args do [env: :prod] -> [worker(Kaffe.Consumer, [])] [env: :test] -> [] [env: :dev] -> [worker(Kaffe.Consumer, [])] [_] -> [] end
Troubleshooting Errors
- No leader error
** (MatchError) no match of right hand side value: {:error, :LeaderNotAvailable}
Solution: Try again. It just needed a minute to warm up.
- Invalid Topic error
** (MatchError) no match of right hand side value: {:error, :InvalidTopicException}
Solution: Your topic shouldn’t have spaces in it, does it?
The end
This should have given you the basic setup for you to start exploring more of this on your own, but there’s lots more you can do with Kaffe so check out sending multiple messages, consumer groups, etc. If you come up with any more troubleshooting errors you’ve solved, let us know by creating an issue here.

--- title: 'Problem 4: Largest palindrome product' author: John Ensley date: '2018-06-29' slug: 004 categories: [] tags: [palindrome] weight: -4 hidedate: true draft: false ---
A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.
Find the largest palindrome made from the product of two 3-digit numbers.
The overall approach for this problem is very simple: we’ll loop through all combinations of two three-digit numbers, multiply them, and see if the product is a palindrome or not. If it is a palindrome, and it’s bigger than any palindrome we’ve seen so far, then we make a note of it. At the end we’ll be left with the largest palindrome product of 3-digit numbers.
There are 900 three-digit numbers, so iterating through all combinations would require \(900*900 = 810,000\) calls to some palindrome-checking function. This could potentially take a long time. For efficiency, we should consider two things. First, we should try to cut down on the number of times we need to check if a number is a palindrome. Second, we should be smart about how we check for palindrome-ness.
Let’s tackle the palindrome function first. There are a few ways we could check whether a number \(x\) is a palindrome. This function converts \(x\) to a vector of digits and then compares it to the reversed version of itself.
is_palindrome1 <- function(x) {
digit_vector <- as.numeric(strsplit(as.character(x), split = '')[[1]])
all(digit_vector == rev(digit_vector))
}
This one builds up a vector of digits using modular arithmetic instead of converting to a string and back to a number as in is_palindrome1
. It again compares the vector to its reverse.
is_palindrome2 <- function(x) {
ndigits <- floor(log10(x)) + 1
digits <- rep(NA, ndigits)
for (i in rev(seq_along(digits))) {
digits[i] <- x %% 10
x <- x %/% 10
}
all(digits == rev(digits))
}
Instead of building up a vector of digits, this one builds up a reversed integer. For example, if \(x = 1234\), reversed
will become \(4321\). Then \(x\) and reversed
are compared.
is_palindrome3 <- function(x) {
n <- x
reversed <- 0
while (x > 0) {
remainder <- x %% 10
reversed <- 10 * reversed + remainder
x <- x %/% 10
}
n == reversed
}
In this one, we aren’t reversing \(x\), but instead we compare the first and last digits of \(x\). If they are not equal, then we already know \(x\) is not a palindrome and we can exit the function without checking the rest. If they are equal, we remove the first and last digit from \(x\) and perform the comparison again on this new \(x\).
is_palindrome4 <- function(x) {
d <- 10^(floor(log10(x)))
r <- 10
while (x > 0) {
dig_first <- x %/% d
dig_last <- x %% r
if (dig_first != dig_last) return(FALSE)
x <- x %% d %/% r
d <- d / 100
}
return(TRUE)
}
is_palindrome4
has the advantage of potentially exiting early, although there are many more modular arithmetic calculations needed than in is_palindrome3
. I’m not sure how fast R can perform numeric to string conversions, so I don’t know how well is_palindrome1
will perform compared to is_palindrome2
. Let’s find out! First let’s test all four functions on a palindromic number. Since products of 3-digit numbers must be 5 or 6 digits, we won’t worry about testing very large numbers.
(m_pal <- microbenchmark::microbenchmark(is_palindrome1(456654),
is_palindrome2(456654),
is_palindrome3(456654),
is_palindrome4(456654),
unit = 'relative',
control = list(warmup = 10)))
## Unit: relative
## expr min lq mean median uq
## is_palindrome1(456654) 2.877637 3.022798 0.9442647 3.048568 1.944165
## is_palindrome2(456654) 3.421941 4.303816 1.9814555 4.282453 2.462348
## is_palindrome3(456654) 1.000000 1.000000 1.0000000 1.000000 1.000000
## is_palindrome4(456654) 1.047468 1.091913 5.6931749 1.128021 1.062437
## max neval
## 0.766827 100
## 1.852763 100
## 1.000000 100
## 6.246050 100
Note that the reported values are relative to the fastest runtime, not absolute speed. The runtimes for all four functions are only a few microseconds, so the actual values really aren’t that important. is_palindrome3
and is_palindrome4
perform just about equally well, and the other two are 2 to 3 times slower. For the sake of completeness, let’s try testing on a non-palindrome as well.
(m_pal <- microbenchmark::microbenchmark(is_palindrome1(468841),
is_palindrome2(468841),
is_palindrome3(468841),
is_palindrome4(468841),
unit = 'relative',
control = list(warmup = 10)))
## Unit: relative
## expr min lq mean median uq
## is_palindrome1(468841) 6.282002 6.048048 5.641997 5.334902 5.097717
## is_palindrome2(468841) 7.355149 6.951952 6.123382 6.078928 5.783747
## is_palindrome3(468841) 2.265640 2.188331 1.952147 1.972846 1.890866
## is_palindrome4(468841) 1.000000 1.000000 1.000000 1.000000 1.000000
## max neval
## 8.6221234 100
## 4.2724811 100
## 0.9727325 100
## 1.0000000 100
As we would expect, is_palindrome4
performs the best because it quits as soon as it encounters digits that do not match. This will probably come in handy, since there are more non-palindromes than palindromes. Let’s go with is_palindrome4
as our final answer.
The next step is to find the largest palindrome product. Again, the general idea is to iterate through all products \(ab\) where \(a\) and \(b\) are three-digit numbers. There are a couple of optimizations that minimize the number of times we’ll need to call is_palindrome4
. First of all, because the largest palindrome will likely be the product of two larger three-digit numbers, we can start with \(a\) and \(b\) equal to 999 and move backwards to 100. That way we’ll probably encounter the largest palindrome sooner.
Second, and more importantly, we don’t need to check whether every single \(ab\) is a palindrome. If \(ab\) is less than the largest palindrome we’ve found so far, then we don’t care if it is also a palindrome.
p4 <- function() {
largest <- -Inf
for (a in 999:100) {
for (b in a:100) {
x <- a*b
if (x > largest && is_palindrome4(x)) {
largest <- x
}
}
}
largest
}
p4()
## [1] 906609
( m <- microbenchmark::microbenchmark(p4(), unit = 'ms') )
## Unit: milliseconds
## expr min lq mean median uq max neval
## p4() 30.38264 30.96605 32.57276 31.55688 33.08853 49.5508 100
The solution takes about 31.6 milliseconds. If the predicates in the if
statement were reversed, i.e. if (is_palindrome4(x) && x > largest)
, it would take about 2 seconds, or roughly 50 times longer.


The Berkeley DB library is intended to support an embedded model of applications, although it is relatively easy to create client-server applications as well.
In the client-server model, a database server is created by writing an application that accepts requests via some form of IPC and issues calls to the Berkeley DB functions based on those queries. In this model, applications are client programs that attach to the server and issue queries. The client-server model trades performance for protection, as it does not require that the applications share a protection domain with the server, but IPC/RPC is generally slower than a function call. In addition, this model simplifies the creation of network client-server applications.
In the embedded model, an application links the Berkeley DB library directly into its address space. This provides for faster access to database functionality, but means that the applications sharing log files, lock manager, transaction manager or memory pool manager have the ability to read, write, and corrupt each other's data.
It is the application designer's responsibility to select the appropriate model for the application.

For a portfolio, this is not off to a strong start. As I have mentioned, these first two weeks have been plagued by pre-existing obligations. This is not an excuse. I have not spent the requisite amount of time necessary to learn CSS, or bootstrap.
I recognize that this is not the foundation I need to move forward.
I am learning, just slowly.

Honda India records sales of 10,010 units in October 2019
by Team ODHonda India recorded a sale number of 10,010 units in October 2019. The sale number is down by 4,177 units as the company sold 14,187 units in the corresponding month last year. The export sales stand at 633 units for October 2019.
Commenting on the sales, Rajesh Goel, Senior Vice President and Director - Sales and Marketing, Honda Cars India Ltd said, "The festive season was rewarding for the auto sector after a prolonged slowdown. The high discounts and other festive offers provided by automakers across the industry resulted in positive consumer sentiment. At Honda, we also saw an increased sales momentum as compared to last few months and are hopeful that this trend will continue in the following months."
Currently, Honda cars India has nine products in its portfolio - Brio, Amaze, Jazz, WR-V, City, BR-V, Civic, CR-V and the Accord. And the company also unveiled India bound next-generation Honda Jazz at this years Tokyo Motor Show. The company has also been spotted testing the next-generation Honda City in the international markets which is likely to be unveiled at the Delhi Auto Expo in 2020. The possible addition of the new sedan and hatchback could help the company bring its sales number up in the first quarter of 2020.

Cannabis |
(plant material) |
Cannabis usually makes me one of two things each time I smoke it. I either get real excited, not nervous but my mind is clouded and has a hard time thinking. If I donít get the above stated, I get deeply relaxed, muscle tension fades, and it feels as though a door has opened and my brain expands until there is ton of open space around my current thoughts.
One such experience was last Saturday. Two friends of mine named Scott and Russ (nicknamed S and R for easier reference) bought some bud and got high before heading to the mall. We packed a few bowls, two namely and smoked then rolled a blunt with the rest of the weed. Between the time we smoked our bowls and rolled the blunt, I was feeling slightly giddy and giggly, yet not high. We rolled the blunt and smoked it to where we couldn't hold it the put it in the bowl and finished it off. I went to stand up and I couldnít. I was feeling as if air was as heavy as water and I could only move my head really slow. When I did finally figure out how to move my head again, it seemed as though my head stayed still but my body and the world are the ones that turned....
We made it into the mall, neither one of us could stop smiling. We were walking around when I was hit with an instant of personal realization. Iím not talking about just getting messed up and heading to the mall for kicks. I instantly realized how big the world actually was. It felt as though time for me stopped but everyone else kept going at the exact same speed, I caught a glimpse of everyone past the mall doing their daily lives. I stopped and took a minute to thank god for letting me see such things and experience such a nice life. For about twenty minutes after that, it felt as though my mind and brain were two different things. My brain seemed to take control of my body and move it for me while my brain laid in the back of my mind and enjoyed the ride... I was doing the same.
Somehow I reached the food-court and we chilled for a little bit at a table when I was staring at S and he was talking in a weird language and telling me to buy a book at Wal-Mart without moving his lips. I asked him what he was saying and he told me I was hearing the Skytron monitor. The Skytron was a huge TV above the food court that played constant commercials. Anyway I stopped and watched the beautiful scene and let my worries fade when R looked at me and asked me if I heard the robot. I was hearing a constant sound for a while now, not realizing it was a robot till R said something. Normally I would get freaked out about something like this and hate myself for smoking bud. This time I said , 'yeah' and sat back and relaxed and lived/loved life for what time I had left till the robot came to kill me. It never did.
I came to realize later on that the robot was nothing merely other then the large jumble of voices eating their lunch and enjoying their life.... that made me happy to see that other people were enjoying their day also. I was coming down from my high by the time we were leaving the mall, however that didn't stop Russ, Scott , and I from enjoying a laughing fit in the car so hard it made my chest hurt.
Smoking weed is fun... I believe it's something for everyone to try at least once and see how they like it. As with beer, if I find myself getting messed up once a week or more, I'm going to cut back.

@Deleted User mac is slow and heats a lot what?
i have a macbook pro, is plenty fast, rarely heats up, usually only when syncing pirate chain for a couple of hours as komodod tends to send the cpu to 200% usage :p
jl777c07-Jun-19 07:32 AM
i will announce later today the method that will be used for early redeems. in order to qualify for this, your address needs to be uncontested and in the swept funds, you need to have filled out the form, and you will need your old compromised privkey to prove you had control of the address. if all these conditions are met and it isnt for a very large amount (size yet to be determined) then I will aim to get them processed before June 15th.
from what i can tell, the vast majority fall into the above category. i will use the blockchain to prove that the repayment has been made. after this first phase of repayments, the number of claimants will be much reduced, but there will still be a lot of KMD left to payout. the second phase will deal with swept funds that are big, but are uncontested. so make sure to fill out your form ASAP.
the third phase will deal with funds that were stolen. at that point all that will be left are the disputed addresses, which will be dealt with on a case by case basis.
the sooner we can complete the refund process the better, so my goal is to complete all phases other than dispute resolutions by the end of this month, but with vast majority of cases before june 15th. thank you for your patience.

You can panic sell into my low buys.
But then I made money in Pirate and have started making money in KMD. Something is wrong.

Btc cannot handle all transactions as it used to, so it is only natural that dominance keep getting lower as there are more transactions

jl777c07-Jun-19 10:47 AM
now that the vast majority of addresses have been claimed, i can reveal the three step process that will be used for processing refunds.
1. a special transaction will be send to your compromised address. it will be for a fraction of a KMD
2. you need to send 0.0001 (or more) from the compromised address to the destination address you specified
3. IF and only IF, your address has no disputes, or contradictory claim info, and the proper destination address receives the special payment, a refund tx will be made. PLEASE do not ask when these refund tx will be made, i am working as fast as i can, so it will happen when it happens.
what do you need to do?
if your claim amount matches the current batches size range check to see if you got the special transaction. Then make sure you only send it to the address you claimed. after that, just wait. i will announce status of each batch.
if you didnt get a special tx, that means your address is under dispute or you filed too many claims or it is the wrong size. PLEASE wait until we process all the problem free cases first. They will be done AFTER the easy cases are done.
Please dont expect any refund payments until june 15, maybe i can get it done sooner, but step 3 is a LOT of custom code that cannot have any errors

first 70 special tx are sent to those with claims smaller than 7 KMD
if you are one of these, please let me know you got funds and then send to your claim address
I want to make sure the basic process works before scaling it up to all the < 7777 addresses
I lost 39KMD from other address, but I donate it to a good people of KMD

Believe it or not, long-term travel can wear you out. After a while we all want to stop. It's not the physical part as one might expect. Actually already after a few months you won't experience this so much anymore. The body easily adapts to getting up my Brooks saddle every day until it's time to get back to sleep on a rocky uneven camp-spot.
Come to think of it, it happened quite a lot that I stopped at rest stations where people complain about sitting in a car for four hours, after I did the same on my saddle without any complaints.
No it's definitely not the body, it's the mind that gets tired after a while. On a trip like this you do a lot of things that would fall into the category "unspeakable" for most people, but like it or not, after a while it becomes your every day life.
Meeting new and different people every day is great, saying goodbye to each and every one of them, is not always that great.
So we felt like staying at one place, meeting the same people and eating in the same places for a while. Since we were a bit tired of the typical South East Asia crowd (more about that later) we decided to go to Nepal instead.
Nepal has been described to us as India light and after the countless stories that we heard about the hardships of traveling through India, that sounded like a good thing.
If I had to describe the country with ten keywords I would probably come up with something like this:
mountains, tourism, hinduism, good food, low budget, colorful, dirty, buddhism, daal bhat, cold
We got a three-months multiple entry visa on arrival at the airport and took a taxi into the touristic center of town: Thamel.
Thamel is awesome, noisy, dirty and colorful. Just the right place to get into the spirit of the South Asian sub-continent. It took us about a week to find an apartment in an area that was to our liking.
Guys you can't believe how great it is to have a real kitchen after such a long time. I'm talking about more than one stove, a fridge, more and cleaner workspace and more storage than one or two Ortlieb bags can provide.
We got into a rhythm pretty soon and we loved it:
- we got up early followed by an ice cold shower (at least I did, Hajar instead attempted to brake my no-shower records which I set during winter/spring in Europe), because the solar heater takes too long
- boil some milk (finally affordable and good milk after having almost no milk products while in South East Asia) and make hot muesli and coffee
- Hajar is a vet and she wanted to get some more practical experience, so she was working in an animal shelter for a month, we both commuted there every day (in the end we cycled about 500km in Kathmandu)
- I went back home and studied Farsi and worked on some nerdy IT stuff
A month can pass quickly, but it was exactly what we needed and now we know where we want to go from here: back to Iran.
I need a visa for Iran, so I'm going to India to pick one up in New Delhi. The waiting time for an Indian visa was too long for Hajar so she will instead take a 10-day Vipassana mediation course.
I get to go to India which is crazy, interesting and beautiful with good food etc. but somehow I'm really jealous. I've always wanted to do something like that, but luckily Vipassana is represented in almost every country, so I'll have other chances to do so.
In general it's a completely free course that lasts ten days. Food and accommodation is provided, but the rules are strict:
- gender separation
- wake up every day at 4 AM
- more than 10 hours of meditation every day
- no talking, writing, reading !!!
Maybe I'll get Hajar to write about her experience after she finished the course otherwise you'll be hearing about my time in India hopefully sooner than later.

===============================================================================
The function in the last comment also converts the string 'false' to a true
boolean. Here's a function that does what I think was intended:
I am woundering why php does not have a function to do this
Motaz Abuthiab
===============================================================================
Just another little function which doesn't exist yet, but I find mighty useful,
especially when working with AJAX and APIs.
* @param mixed $in The variable to check
* @param bool $strict If set to false, consider everything that is not false to
* be true.
* @return bool The boolean equivalent or null
*/
function boolval($in, $strict=false) {
$out = null;
// if not strict, we only have to check if something is false
if (in_array($in,array('false', 'False', 'FALSE', 'no', 'No', 'n', 'N', '0'
, 'off',
'Off', 'OFF', false, 0, null), true)) {
$out = false;
} else if ($strict) {
// if strict, check the equivalent true values
if (in_array($in,array('true', 'True', 'TRUE', 'yes', 'Yes', 'y', 'Y',
'1',
'on', 'On', 'ON', true, 1), true)) {
$out = true;
}
} else {
// not strict? let the regular php bool check figure it out (will
// largely default to true)
$out = ($in?true:false);
}
return $out;
}
?>
It may be pretty inefficient, but it does the job.
===============================================================================
punkpuke is wrong here; what he means to say is that empty($x) is the opposite
of (bool)$x. is_bool($x) returns true where $x === false.
===============================================================================
For those of you who think that micro-optimization is important:
It's quicker to strictly compare a value to TRUE and FALSE, than using is_bool
(), because it's a function.
===============================================================================
@ emanueledelgrande at email dot it
http://us.php.net/manual/en/language.types.type-juggling.php
(bool) or (boolean) is allowed for type casting a variable. No function like
intval, etc but the functionality exists.
===============================================================================
@ emmanuel del grande
You don't need to break when you return...
function bool($var) {
switch (strtolower($var)) {
case ("true"): return true;
case ("false"): return false;
default: die("whatever you want it to tell");
}
}
===============================================================================
I think there's a hole in the PHP typecasting methods:
you have the (int) function, the (float) function and the (string) function,
but no function to force a string variable into the boolean type.
It's obvious that forcing unconditionally the type of variables into arrays and
objects is inappropriate, but boolean type is the most basic one for each
programming language, that's why I guessed that a (bool) function already
existed.
Moreover, with the increasing trend of RSS data streaming, the parsing of an
XML string into an object often requires to typecast as boolean values the
content of XML tags, normally returned as string by the object method
get_content().
I wrote the following function, which also uses a "native PHP style" error
message:
\nWarning: Invalid argument supplied for ".
__FUNCTION__." function in ".__FILE__." on line ".__LINE__.": the
argument can contain only 'true' or 'false' values as a string.
\n");
}
}
?>
Here it is a small example:
";
$xmlResponse .= "";
$xmlResponse .= "false";
$xmlResponse .= "true";
$xmlResponse .= "";
if (! $responseDoc = domxml_open_mem($xmlResponse, DOMXML_LOAD_PARSING,
$XmlParsingError)) {
echo "Error while parsing the XML string:
".print_r($XmlParsingError,
TRUE);
} else {
$ResultNode = $responseDoc->get_elements_by_tagname('Result');
$AuthError = $ResultNode[0]->get_elements_by_tagname('AuthError');
$auth_error = bool($AuthError[0]->get_content());
$TransferStatus = $ResultNode[0]->get_elements_by_tagname('TransferStatus'
);
$transfer_status = bool($TransferStatus[0]->get_content());
if (! $auth_error) { echo "Auth OK
"; } else { echo "Auth error
"
; }
if ($transfer_status) { echo "Transfer OK
"; } else { echo "Transfer
error
"; }
}
?>
It would be useful this function to be implemented in the core of PHP5.
