Boxifying design means that all the presentation views in a webpage can be cut into smaller pieces of rectagular shape. A heading title can be cut into a rectangular shape; a paragraph can be cut into a rectangular shape; a circle can be cut into a rectangular shape; an image can be cut into a rectangular shape. When viewing all piece of visual elements in design mocks as various rectangular shapes, a web developer could reproduce the design through html and CSS coding.
Box Model is a term for CSS. Box Model means a visible/invisible box wrapping around an HTML element. Box Model is consist of margins, borders, padding, and the actual content.

Docker is an amazing tool with a lot great functional command line interfaces. A typical docker deployment might have a webapp running inside a container. In order to observe the beahvior of this container you might want to setup a Nagios plugin to monitor log output.
To do this I am going to do the following:
Deploy an Ubuntu Precise VM on <IP_ADDRESS> via Vagrant
Provsion the VM with Puppet using the Vagrant Puppet provisioner:
Installs docker using garethr-docker
Installs the training/webapp image
Runs the container using an exec
Installs nagios and my ruby plugin to monitor the docker service and the training/webapp image for the following:
Is the docker command available?
Is the webapp running?
Ensures webapp is running on localhost:5000
Checks the log for 404 errors and sends warnings if so
Counts the errors for each URL with a 404 and outputs the count and URL which has the highest hit count
test the above by trying <IP_ADDRESS>:5000/test over and over again
The Vagrantfile
I start with a basic Vagrantfile to deploy an Ubuntu Precise VM:
123456789101112131415
Vagrant.configure("2") do |config|
config.vm.provider "virtualbox" do |v|
v.customize ["modifyvm", :id, "--memory", 1024]
end
config.vm.define :nagios do |deploy|
deploy.vm.box = "precise64"
deploy.vm.hostname = "nagios.server.dev"
deploy.vm.box_url = "http://files.vagrantup.com/precise64.box"
deploy.vm.synced_folder "modules", "/etc/puppet/modules"
deploy.vm.synced_folder "manifests", "/etc/puppet/manifests"
deploy.vm.network :private_network, ip: "<IP_ADDRESS>" # Define static IP once dev completes
deploy.vm.provision :puppet, :module_path => "modules", :manifests_path => "manifests", :manifest_file => "deploy_nagios.pp"
end
end
Puppet Provisioner
In order to provision the VM on boot I used the Puppet provisioner which ships with Vagrant. For testing purposes I like to sync my manifests and modules directory to the VM. Usually I run a bash script before provisioning with Puppet to install from the Puppet Labs apt or yum repos, however for this project that wasn’t neccessary as the goal is to have a quickly bootable dev environment for my Nagios server and Docker container.
# Deploy docker and an Ubuntu image to play with
class {'docker':}
docker::image { 'training/webapp':
require => Class['docker'],
}
# Super hero hack to run the docker image... see readme for why.
# Also, in no way is this idempotent, if it's running it'll fail.
exec { '/usr/bin/docker run -d -p 5000:5000 training/webapp python app.py':
require => Docker::Image['training/webapp'],
}
#docker::run { 'webapp':
# image => 'ubuntu',
# command => '/bin/echo test',
# require => Docker::Image['training/webapp'],
#}
# Update this thing
exec { '/usr/bin/apt-get update':}
# Install nagios
class { 'nagios':
require => [Exec['/usr/bin/apt-get update'],Class['docker']]
}
# Get my plugin on the system correctly
nagios::plugin { 'docker_status':
source => 'nagios/nagios-plugins/docker_status.rb'
}
# WARNING: TOTAL HACK PLEASE DON'T JUDGE ME
exec { '/bin/echo "command[docker_status]=/usr/lib/nagios/plugins/docker_status" >> /etc/nagios/nrpe.cfg':
require => File['/etc/nagios/nrpe.cfg'],
notify => Service['nrpe'],
}
# Ensure docker and nagios are in the same group
exec {'/usr/sbin/usermod -a -G docker nagios':
require => Class['nagios'],
notify => Service['nrpe'],
}
nagios::command { 'docker_status':
command_line => '$USER1$/check_nrpe -H $HOSTADDRESS$ -c docker_status',
}
# Set the nagiosadmin password
exec { '/usr/bin/htpasswd -cb /etc/nagios3/htpasswd.users nagiosadmin nagiosadmin':
require => Class['nagios'],
}
# I wrote my plugin in Ruby so lets make sure the VM has it.
package { 'ruby1.9.1':
ensure => present,
require => Class['nagios'],
}
Yup, I had a couple of hero hacks in there to get around some issues with the docker::run define. That define should work, but kept failing with a very odd ‘<< is not a {}:hash’ error. I grep'ed through the module to try and find where this was coming from and I think it’s a heredoc within a function for the define. I still need to look into it. I ran an exec after the image is downloaded to get around this problem.
I also hero hacked the update to the nrpe.cfg file as the Nagios module I used didn’t make it clearly evident how or if it did this.
… In no way do any of these hacks make me an “inpatient” person.
The Nagios Plugin
Recall my plugin should monitor:
Is the docker command available?
Is the webapp running?
Ensures webapp is running on localhost:5000
Checks the log for 404 errors and sends warnings if so
Counts the errors for each URL with a 404 and outputs the count and URL which has the highest hit count
test the above by trying <IP_ADDRESS>:5000/test over and over again
Let’s break it down
Nagios Basics:
First, let’s define some basic outputs for the Nagios API. Since Nagios is only looking for specific exit codes from any given script we define those as methods here first.
0 = OK
1 = Shit is potentially hitting the fan
2 = Shit is hitting the fan
3 = Unknown shit is happening
The first part of my Plugin defines these:
12345678910111213141516171819202122232425
#!/usr/bin/ruby
# Checks the docker status command for number of running containers
# Ensures the docker container is running by checking that the socket exists
#
# Define some helper methods for Nagios with appropriate exit codes
def ok(message)
puts "OK - #{message}"
exit 0
end
def critical(message)
puts "Critical - #{message}"
exit 2
end
def warning(message)
puts "Warning - #{message}"
exit 1
end
def unknown(message)
puts "Unknown - #{message}"
exit 3
end
Check to ensure docker is installed
Now let’s check to ensure Docker is installed, we can use a simple system() method which returns exit codes only:
1234567
def docker_installed()
if system("which docker > /dev/null")
webapp_status()
else
critical("Docker isn't installed")
end
end
Yup, it’s that easy, which docker will return ‘0’ or ‘false’ if it does not find the command and ‘1’ or ‘true’ if a path to the command is found. This isn’t the most robust check ever, but for now it’s enough to move on. Since all my other def’s work on the docker face and it’s sub commands I need to ensure this is present before doing anything else.
Check the webapp status
First, I want to make sure the webapp is running on the VM on a specific port. I’m going to use a netstat command and awk to return the process running on port 5000:
12345
def webapp_status()
# Ensure the webapp is running on localhost:5000
webapp_run = `netstat -anp | grep 5000 | awk '{print $7}' | cut -d/ -f2`
should_be = "docker"
webapp_run.chomp!.strip!
if webapp_run == should_be
# Check to ensure there are no 404 errors in the log
check_this = "docker logs $(docker ps -l | awk '{print $1}' | awk '{if (NR == 2){print $0}}') 2>&1 | grep 404 | awk '{print $7}' | sort | uniq -c"
check = system(check_this)
if check
IO.popen(check_this) do |io|
line = io.readlines
errors = {}
line.each do |this|
number = this.split(' ').first
url = this.split(' ').last
errors.store(url, number)
end
max_value = errors.values.max
max_key = errors.select { |k,v| v==max_value }.keys
case max_value.to_i > 20
when false
warning("#{max_value} 404 Errors at localhost#{max_key}")
when true
critical("#{max_value} 404 Errors at localhost#{max_key}")
end
end
Lot’s of things are happening there.
1st, if ‘docker’ is the output of the webapp status command we drop into another loop. This loop runs a check_this command that is derived from the docker log face. That particular face feeds the output from a sys-log-like to the terminals stdin.
But first, docker logs needs to have the process hash of the container you want to query, so I run a docker ps -l and awk for the hash of the process I want.
123
root@nagios:/home/vagrant# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c968cced9f32 training/webapp:latest python app.py 33 minutes ago Up 33 minutes <IP_ADDRESS>:5000->5000/tcp berserk_pare
This would definitely break if you had many containers running.
So anyways, if we have that hash we can now pass it to docker logs like I did in the ruby script like this:
12
root@nagios:/home/vagrant# docker logs c968cced9f32
* Running on http://<IP_ADDRESS>:5000/
Tight.
Now that I have access to the log from the webapp I can grep URL’s which have 404 errors, add those to a hash as k,v’s and then iterate over the hash for the key with the largest value.
12345678910
IO.popen(check_this) do |io|
line = io.readlines
errors = {}
line.each do |this|
number = this.split(' ').first
url = this.split(' ').last
errors.store(url, number)
end
max_value = errors.values.max
max_key = errors.select { |k,v| v==max_value }.keys
Now I can use that key’s value to hit my warning or critical methods.
123456
case max_value.to_i > 20
when false
warning("#{max_value} 404 Errors at localhost#{max_key}")
when true
critical("#{max_value} 404 Errors at localhost#{max_key}")
end
Of course, the end to this giant loop of loops does…
1234567
else
ok("Docker & Webapp are in good shape!")
end
else
critical("Webapp is not running on localhost:5000")
end
end

# Ensures the docker container is running by checking that the socket exists

end
def critical(message)
puts "Critical - #{message}"
exit 2

def warning(message)

end

else

end
end
def webapp_status()

webapp_run = `netstat -anp | grep 5000 | awk '{print $7}' | cut -d/ -f2`
should_be = "docker"
webapp_run.chomp!.strip!
if webapp_run == should_be
# Check to ensure there are no 404 errors in the log
check_this = "docker logs $(docker ps -l | awk '{print $1}' | awk '{if (NR == 2){print $0}}') 2>&1 | grep 404 | awk '{print $7}' | sort | uniq -c"

Russia drafting law to bar dopers from working in sports - minister
Russia is drawing up legislation that would bar people serving doping suspensions from working as sports officials or in sports schools, Sports Minister Pavel Kolobkov said on Wednesday, as the country boosts efforts to put its doping scandals behind it.
MOSCOW: Russia is drawing up legislation that would bar people serving doping suspensions from working as sports officials or in sports schools, Sports Minister Pavel Kolobkov said on Wednesday, as the country boosts efforts to put its doping scandals behind it.
Russia has faced heightened scrutiny in recent months after Reuters reported that two athletics coaches and one doctor suspended for doping were still working with athletes.
Another Reuters report in June found that race walking coach Viktor Chegin, banned for life in 2016, had been awarded state contracts to provide security at the venue where he was formerly head coach.
"We are working on amendments to the law on sport that would allow us to bar people suspended (for doping) from working in sport, including in state and municipal posts, from running youth sports schools," Kolobkov was quoted as saying by TASS news agency.
"We don't have this in our law for now, but it must be adopted."
Kolobkov did not provide any timeline for these potential legislative amendments, nor did he say whether the measures would apply to both athletes and athlete support personnel.
He did not provide any detail on the proposed consequences for violating these measures.
Athletes must not receive training, strategy, nutritional or medical advice from banned coaches or medical staff and can face sanctions if they do, according to World Anti-Doping Agency (WADA) rules.
Russia's participation at next year's Tokyo Olympics is now at risk after WADA found "inconsistencies" in the vast bank of testing data handed over from Moscow earlier this year.

"The future belongs to those who believe in the beauty of their dreams."
-Eleanor Roosevelt
Research has shown that it takes one-tenth of a second for a person to look at your picture and form an impression about your personality.
A recent study investigated several low level features such as saturation, hue and contrast as well as high level features such as face size, setting, dress style, glasses, smile, background, head tilt etc. that influence our impression of images.
Saving Face looks at some of these elements and provides users with feedback about what they can do to improve the quality of pictures.
We first used Microsoft’s Cognitive Service Vision API, in particular the Face API that detects human faces and returns face attributes containing machine learning-based predictions of facial features. Of the available features, we used low level features such as exposure, noise and blur and high level features such as emotion (anger, contempt, disgust, fear, happiness, neutral, sadness and surprise), smile, and accessories such as sunglasses. Additionally, we used Google’s Logo Detection API that detects product logos within an image.

Pong
The classic Pong game -- the grandfather of all video games! Now over 45 years old!
Difficulty: Easy
Objective: Retro gaming
How It Works
Suprisingly, this very simple game requires about as much code as the Space Invasion game.
In this game a single player plays against the BrainPad. The player uses the up and down buttons to move his paddle (on the right side of the screen) and tries to hit a moving ball across the net (the dashed line) to the other side of the court. You score points when the BrainPad misses the ball. The BrainPad scores when you miss the ball. The first player (you or the BrainPad) to get five points wins.
An Exercise
Modify the code to so tilt (the accelerometer) is used instead of buttons. Hint: Use the Tilt Etch A Sketch for help.
The Code
using System;
using System.Collections;
using System.Text;
using System.Threading;
using GHIElectronics.TinyCLR.BrainPad;
namespace Pong {
class Program {
static void Main() {
double BallX = 10, BallY = 10, BallDX = 2.3, BallDY = 2.8;
int ScoreL = 0, ScoreR = 0;
int PlayerPos = 30;
int CompPros = 30;
BrainPad.Display.DrawRectangle(0, 0, 128, 64);
while (true) {
// The Ball
BrainPad.Display.ClearPartOfScreen((int)BallX, (int)BallY, 4, 4);
BallX += BallDX;
BallY += BallDY;

Royal Mail tries to stop Christmas postal strike
Royal Mail is seeking a High Court injunction to stop a postal strike, claiming that the ballot of workers had "potential irregularities".
The company said it would make a formal application on Friday that the strike ballot "was unlawful and, therefore, null and void".
A strike threatens to disrupt postal voting in the run-up to the general election as well as Christmas post.
The Communications Workers Union says it "refutes" Royal Mail's claim.
The ballot of 100,000 Royal Mail staff was held over job security and terms. No dates for a strike have yet been set.
Members of the Communications Workers Union (CWU) last month voted by 97% in favour of a nationwide strike, saying the company had failed to adhere to an employment deal agreed last year. Royal Mail rejects this, which is why there are no grounds for industrial action, it says.
In the company's statement on Friday, Royal Mail said it had evidence of CWU members coming under pressure to vote "yes" in the ballot.
This included, the company claimed, union members "being encouraged to open their ballot papers on site, mark them as 'yes', with their colleagues present and filming or photographing them doing so, before posting their ballots together at their workplace postboxes".
Royal Mail's procedures state employees cannot open their mail at delivery offices without the prior authorisation of their manager.
CWU general secretary Dave Ward said: "It will be clear to all our members and everybody connected with Royal Mail and this dispute, that the chief executive and his board will go to any lengths to deny the democratic mandate of our members to stand together and fight for their future and the very future of UK postal services."
He said the CWU had made it clear to Royal Mail that it was willing to talk, including through this weekend.
A High Court hearing into Royal Mail's application for the injunction is expected to be heard early next week.
Royal Mail has previously told the union that if it removed the threat of industrial action for the rest of 2019, the company would enter talks without preconditions. But the CWU called Royal Mail's offer a "stunt" which the union would not fall for.
Industrial relations at the company have worsened this year, with frequent unofficial strikes breaking out.
The CWU has said the result of the ballot, held between 24 September and 15 October, represents the largest "yes" vote for national industrial action since the passing of the Trade Union Act 2016.
The union claims that up to 50,000 jobs are at risk at Royal Mail and Parcelforce, under plans to separate Parcelforce from the postal business. Shane O'Riordain, Royal Mail's managing director of regulation and corporate affairs, described this as "unfounded speculation"

| IOCTL_NS(2) | Linux Programmer's Manual | IOCTL_NS(2) |
new_fd = ioctl(fd, request);
In each case, fd refers to a /proc/[pid]/ns/* file. Both operations return a new file descriptor on success.
The new file descriptor returned by these operations is opened with the O_RDONLY and O_CLOEXEC (close-on-exec; see fcntl(2)) flags.
By applying fstat(2) to the returned file descriptor, one obtains a stat structure whose st_dev (resident device) and st_ino (inode number) fields together identify the owning/parent namespace. This inode number can be matched with the inode number of another /proc/[pid]/ns/{pid,user} file to determine whether that is the owning/parent namespace.
Either of these ioctl(2) operations can fail with the following errors:
Additionally, the NS_GET_PARENT operation can fail with the following error:
See the EXAMPLE section for an example of the use of these operations.
nstype = ioctl(fd, NS_GET_NSTYPE);
fd refers to a /proc/[pid]/ns/* file.
The return value is one of the CLONE_NEW* values that can be specified to clone(2) or unshare(2) in order to create a namespace.
uid_t uid; ioctl(fd, NS_GET_OWNER_UID, &uid);
fd refers to a /proc/[pid]/ns/user file.
The owner user ID is returned in the uid_t pointed to by the third argument.
This operation can fail with the following error:
Trying to get the parent of the initial user namespace fails, since it has no parent:
$ ./ns_show /proc/self/ns/user p The parent namespace is outside your namespace scope
Create a process running sleep(1) that resides in new user and UTS namespaces, and show that the new UTS namespace is associated with the new user namespace:
$ unshare -Uu sleep 1000 & [1] 23235 $ ./ns_show /proc/23235/ns/uts u Device/Inode of owning user namespace is: [0,3] /<PHONE_NUMBER> $ readlink /proc/23235/ns/user user:[4026532448]
Then show that the parent of the new user namespace in the preceding example is the initial user namespace:
$ readlink /proc/self/ns/user user:[4026531837] $ ./ns_show /proc/23235/ns/user p Device/Inode of parent namespace is: [0,3] /<PHONE_NUMBER>
Start a shell in a new user namespace, and show that from within this shell, the parent user namespace can't be discovered. Similarly, the UTS namespace (which is associated with the initial user namespace) can't be discovered.
$ PS1="sh2$ " unshare -U bash sh2$ ./ns_show /proc/self/ns/user p The parent namespace is outside your namespace scope sh2$ ./ns_show /proc/self/ns/uts u The owning user namespace is outside your namespace scope

The teaching team placed the four of us in the same group because of our desire to provide service to our communities. After hours of discussion and bouncing ideas off of one another, we hit our first wall. It seemed neraly impossible to condense our broad range of interests into one project. However, not long after, we agreed to focus on developing a method to combat Gerrymandering thanks to John Oliver's video on Youtube. We were all excited to start working because it was a a relevant topic that also satisfied all of our interests.

Tun Mahathir says it's up to him to decide on Cabinet changes
by BernamaPUTRAJAYA (Nov 21): Prime Minister Tun Dr Mahathir Mohamad said today it is up to him to decide on the changes when it comes to a Cabinet reshuffle, including which Minister should be dropped.
Anyone is free to express his or her opinion on the possibility of a Cabinet reshuffle, he said when met after having officiated at the soft launch of the Kuala Lumpur Summit 2019 here.
"People can express their own opinion but I will decide if it is agreed to by the five parties forming the coalition," he said when responding to a question.
Yesterday, Dr Mahathir hinted at the possibility of a Cabinet reshuffle in the wake of the defeat of the Pakatan Harapan (PH) in the Tanjung Piai Parliamentary by-election last Saturday.
Dr Mahathir, who is also PH chairman and Bersatu chairman, had said that the decision on the matter “would not be made today or tomorrow”.

Managing Connections using the Java SDK with Couchbase Server
This section describes how to connect the Java SDK to a Couchbase cluster and bucket. It contains best practices as well as information on SSL and other advanced connection options.
Connecting to a Bucket
Connecting to a bucket is a two-step process: first, a CouchbaseCluster
object needs to be initialized, followed by one or more calls to openBucket():
Cluster cluster = CouchbaseCluster.create();
Bucket bucket = cluster.openBucket();
If no further arguments are applied, this code connects to localhost
and opens the default bucket.
While this is suitable for development, you most probably want to connect to a remote cluster and also a different bucket (with a password):
Cluster cluster = CouchbaseCluster.create("<IP_ADDRESS>", "<IP_ADDRESS>");
Bucket bucket = cluster.openBucket("myapp", "password");
Alternatively, a list of nodes can be passed in:
List<String> nodes = Arrays.asList("<IP_ADDRESS>", "<IP_ADDRESS>");
Cluster cluster = CouchbaseCluster.create(nodes);
The Java SDK also offers limited support for creating a cluster from a Couchbase connection string:
String connectionString = "couchbase://<IP_ADDRESS>,<IP_ADDRESS>";
CouchbaseCluster cluster = CouchbaseCluster.fromConnectionString(connectionString);
| When creating a cluster from a connection string, the Java SDK ignores the scheme component; if a secure connection is desired, the Couchbase environment must be configured as described in Connecting with SSL. The Java SDK also ignores any options in the connection string, and will not work with a connection string that specifies a bucket name. |
|
From Couchbase Java SDK 2.6.0, If using Docker Swarm, or otherwise running the SDK inside the NAT, then you will want to disable with Note that any SSL/TLS certificates must be set up at the point where the connections are being made. The Couchbase SDKs will honor any valid SSL/TLS certificates. |
It is very important in a production setup to pass in at least two or three nodes of the cluster because if the first one in the list fails the other ones can be tried. After initial contact is made, the bootstrap list provided by the user is thrown away and replaced with a list provided by the server (which contains all nodes of the cluster).
More buckets can be open at the same time if needed:
Bucket bucket1 = cluster.openBucket("bucket1", "password");
Bucket bucket2 = cluster.openBucket("bucket2", "password");
If more than one bucket is open at a time, the underlying core-io
library makes sure to utilize the resources as best as possible, that is sharing sockets, thread pools and so on.
Here are some very important things to keep in mind:
-
Always create only one instance of a
CouchbaseCluster
and share it across threads (same with buckets). -
The SDK is thread-safe, so no additional synchronization is needed when interacting with the SDK.
-
If different clusters need to be accessed, reuse the
CouchbaseEnvironment
(See Scalability and Concurrency).
If the underlying environment is not shared the application will continue to work, but a warning is raised in the logs:
WARNING: More than 1 Couchbase Environments found (N), this can have severe impact on performance and stability. Reuse environments!
In general, this is an indication of misconfiguration, the only exception being unit and integration tests where multiple paths are executed at once and cannot share the ClusterEnvironment
for whatever reason.
Disconnecting from a Bucket
The most common case is to disconnect the whole CouchbaseCluster
from the server, which has the same effect as closing all buckets manually and in addition close all underlying resources like thread pools.
This also means that once disconnect has happened, you can’t reopen buckets from the same Cluster
instance.
Boolean disconnected = cluster.disconnect();
If the ClusterEnvironment
is shared it needs to be closed manually, but if not (which is the regular case) it gets also shut down.
After a disconnect, it is not possible to open buckets again, so only use it when you are sure that you do not need access to a CouchbaseCluster
again.
If you only want to close a bucket, you can do that without shutting down everything:
Boolean closed = bucket.close();
This will release only the resources allocated for this bucket and it is possible to reopen it at a later point.
All threads used by the SDK are daemon threads, so even if you do not disconnect()
manually, your JVM will exit.
It is very important that you properly shut down the SDK so that remaining operations are finished and nothing is left behind.
If no timeout is used for the synchronous disconnect()
method, the environment disconnect timeout
is used, which defaults to 25 seconds.
This holds also true if you call close()
on a bucket.
Connecting Asynchronously
Every synchronous API is just a wrapper around an asynchronous one. To get to it, you can use one of these methods:
-
Use
async()
on the interface to access itsAsync*
counterpart. -
Instantiate a
CouchbaseAsyncCluster
in the first place.
So if you are connecting to the bucket synchronously but then want to switch over to asynchronous data operations, you can do it like this:
Cluster cluster = CouchbaseCluster.create();
Bucket bucket = cluster.openBucket();
// Same API as Bucket, but completely async with Observables
AsyncBucket asyncBucket = bucket.async();
On the other hand, you can use the Async API right from the beginning:
AsyncCluster cluster = CouchbaseAsyncCluster.create();
Observable<AsyncBucket> bucketObservable = cluster.openBucket();
Scalability and Concurrency
As mentioned previously, you should create only one instance of a CouchbaseCluster and open buckets from there.
If you need to connect to multiple clusters though, this is not going to work.
To keep things efficient, you should share the CouchbaseEnvironment
object between those instances:
CouchbaseEnvironment env = DefaultCouchbaseEnvironment.create();
CouchbaseCluster cluster1 = CouchbaseCluster.create(env, "<IP_ADDRESS>");
CouchbaseCluster cluster2 = CouchbaseCluster.create(env, "<IP_ADDRESS>");
This ensures that the resources in the environment (thread pools for I/O and computation) are reused. Note that if you pass in your custom environment, it needs to be shut down manually because it’s not under the complete control of any cluster. The recommended approach is to first shut down all clusters and after this is done shut down the environment (here using asynchronous code, but you can also loop synchronously):
Observable
.just(cluster1, cluster2)
.flatMap(CouchbaseCluster::disconnect)
.last()
.flatMap(aBoolean -> env.shutdown())
.toBlocking()
.single();
Connecting with SSL
Couchbase Server EE 3.0 and later supports full encryption of client-side traffic. That includes key-value type operations, queries, and configuration communication. Make sure to have a proper Couchbase Server version installed before proceeding with configuring encryption on the client side.
To configure encryption for the Java SDK:
-
Load and import the certificate from the cluster into your JVM keystore
-
Enable encryption on the client side and point it to the keystore
The JVM keystore is independent of the Java SDK, so your own setup might look different. It is important to make sure you are transferring the certificate in an encrypted manner from the server to the client side, so either copy it through SSH or through a similar secure mechanism.
If you are running on localhost
and just want to enable it for a development machine, just copying and pasting it suffices.
Navigate in the admin UI to and copy the input box of the SSL certificate into a file on your machine (here named cluster.cert).
It looks similar to this:
-----BEGIN CERTIFICATE----- MIICmDCCAYKgAwIBAgIIE4FSjsc3nyIwCwYJKoZIhvcNAQEFMAwxCjAIBgNVBAMT ASowHhcNMTMwMTAxMDAwMDAwWhcNNDkxMjMxMjM1OTU5WjAMMQowCAYDVQQDEwEq MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAzz2I3Gi1XcOCNRVYwY5R ................................................................ mgDnQI8nw2arBRoseLpF6WNw22CawxHVOlMceQaGOW9gqKNBN948EvJJ55Dhl7qG BQp8sR0J6BsSc86jItQtK9eQWRg62+/XsgVCmDjrB5owHPz+vZPYhsMWixVhLjPJ mkzeUUj/kschgQ0BWT+N+pyKAFFafjwFYtD0e5NwFUUBfsOyQtYV9xu3fw+T2N8S itfGtmmlEfaplVGzGPaG0Eyr53g5g2BgQbi5l5Tt2awqhd22WOVbCalABd9t2IoI F4+FjEqAEIr1mQepDaNM0gEfVcgd2SzGhC3yhYFBAH//8W4DUot5ciEhoBs= -----END CERTIFICATE-----
Now, use the keytool
command to import it into your JVM keystore.
Use the -keystore option to specify where to create the keystore.
If you don’t use this option, the default location is the .keystore file in user’s home directory.
|
$ keytool -importcert -file cluster.cert
Enter keystore password:

Issuer: CN=*

You can verify with keytool -list
:
$ keytool -list
Enter keystore password:

Your keystore contains 1 entry
mykey, Aug 18, 2014, trustedCertEntry,
Certificate fingerprint (SHA1): 3A:BC:48:3C:0F:36:99:EB:35:76:7C:E5:14:DE:89:DE:AE:79:9B:ED
The next step is to enable encryption and pass it the path and password of the file.
CouchbaseEnvironment env = DefaultCouchbaseEnvironment
.builder()
.sslEnabled(true)
.sslKeystoreFile("/path/tokeystore")
.sslKeystorePassword("password")
.build();
Alternatively, since 2.3.0 it is possible to point it directly to a keystore that has been previously initialized so it can be created from different sources:
KeyStore myKeystore = loadKeystore();
CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder()
.sslEnabled(true)
.sslKeystore(myKeystore)
.build();
Depending on the OS used there are different default passwords and paths, so consult the JDK manual if you need further information on keytool (Java 7 for Windows and Unix) and the JVM keystore.
There are no other application changes needed.
If you want to verify it’s actually working ,you can use a tool like tcpdump
.
For example, an unencrypted upsert request looks like this (using sudo tcpdump -i lo0 -A -s 0 port 11210
):
E..e<EMAIL_ADDRESS>.E...Ey........9........................id{"key":"value"}
After enabling encryption, you cannot inspect the traffic in cleartext (same upsert request, but watched on port 11207 which is the default encrypted port):
E<EMAIL_ADDRESS>..... ...xuG.O=.#.........?.Q)8..D...S.W.4.-#....@7...^.Gk.4.t..C+......6..)}......N..m..o.3...d.,. ...W.....U.. .%v.....4....m*...A.2I.1.&.*,6+..#..#.5
Using DNS SRV records
As an alternative to specifying multiple hosts in your program, you can get the actual bootstrap node list from a DNS SRV record. The following steps are necessary to make it work:
-
Set up your DNS server to respond properly from a DNS SRV request.
-
Enable it on the SDK and point it towards the DNS SRV entry.
Your DNS server should be set up like this (one row for each bootstrap node):
_couchbase._tcp.example.com. 3600 IN SRV 0 0 0 node1.example.com. _couchbase._tcp.example.com. 3600 IN SRV 0 0 0 node2.example.com. _couchbase._tcp.example.com. 3600 IN SRV 0 0 0 node3.example.com.
| The ordering, priorities, ports and weighting are completely ignored and should not be set on the records to avoid ambiguities. |
If you plan to use secure connections, you use _couchbases
instead:
_couchbases._tcp.example.com. 3600 IN SRV 0 0 0 node1.example.com. _couchbases._tcp.example.com. 3600 IN SRV 0 0 0 node2.example.com. _couchbases._tcp.example.com. 3600 IN SRV 0 0 0 node3.example.com.
DNS SRV bootstrapping is available in the Java SDK from version 2.1.0.
In order to make the SDK actually use the SRV records, you need to enable DNS SRV on the environment and pass in the host name from your records (here example.com
):
CouchbaseEnvironment env = DefaultCouchbaseEnvironment
.builder()
.dnsSrvEnabled(true)
.build();
Cluster cluster = CouchbaseCluster.create(env, "example.com");
If the DNS SRV records could not be loaded properly you’ll get the exception logged and the given host name will be used as a A record lookup.
WARNING: DNS SRV lookup failed, proceeding with normal bootstrap. javax.naming.NameNotFoundException: DNS name not found [response code 3]; remaining name '_couchbase._tcp.example.com' at com.sun.jndi.dns.DnsClient.checkResponseCode(DnsClient.java:651) at com.sun.jndi.dns.DnsClient.isMatchResponse(DnsClient.java:569)
Also, if you pass in more than one node, DNS SRV bootstrap will not be initiated:
INFO: DNS SRV enabled, but less or more than one seed node given. Proceeding with normal bootstrap.

Putin says new weapons unrivalled anywhere in world, won't be used for threats
by The Associated Press, StaffMOSCOW -- Russian President Vladimir Putin said Wednesday that Russia's new weapons have no foreign equivalents but he insists the country will not use them to threaten anyone.
Speaking during a meeting with senior military officers, Putin said that "we plan to build up our defence capability, commissioning hypersonic, laser and other new weapons systems that other countries don't have."
"Yet it's not a reason to threaten anyone," he added.
The Russian leader claimed that the new weapons systems are designed exclusively to "ensure our security in view of the growing threats," and vowed to pursue arms control efforts.
Russia's relations with the West have plunged to the lowest levels since the Cold War years over the conflict in Ukraine and other disputes.
In 2018, Putin announced an array of new weapons, including a new heavy intercontinental ballistic missile, a hypersonic glide vehicle, a nuclear-armed underwater drone and a nuclear-powered cruise missile.
