You're given an array containing both positive and negative integers and
required to find the subarray with the largest sum (O(N) a la KBL).
Write a routine in C for the above.
determine if there are any duplicates in it.
 [I ended up giving about 4 or 5 different
solutions
for this, each supposedly better than the others ]. How about finding
both

4.
Write a routine to draw a circle (x ** 2 + y ** 2 = r ** 2) without making
use of any floating point computations at all.

computations ].
5.
Given only putchar (no sprintf, itoa, etc.) write a routine putlong that
prints out an unsigned long in decimal.
[I gave the obvious solution of
taking % 10 and / 10, which gives us the decimal value in reverse order.
This requires an array since we need to print it out in the correct
order.

I was shown a c++ code and was asked to find out the bug in that. The bug
was that he declared an object locally in a function and tried to
return the pointer to that object. Since

have 0 as the first bit. You just keep accumulating the characters
in a buffer. Suppose at some point the user types a backspace, how can
you remove the character efficiently. ( Note: You cant store the last
character typed because the user can type in arbitrarily many backspaces)

operations, where N is the number of bits in the integer (eg 32,64..)
15.
What is the simple way to check if the sum of two unsigned integers have
resulted in an overflow. (why does the algorithm only works for unsigned
numbers? )
Solution:

list and see if at anytime they meet.
13. Scan the bytes backward till you reach one with the first bit
set to 0. Now this is either a one byte character or the second
byte of a two byte one. Either way it marks a Character boundary.
Start from there and scan forward to find what the last character is.
14. Flip adjacent bits, then flip adjacent 2 bit sets, then 4-bits

Clears everything about the current circuit's state, so that it is as if you have just opened the file again. If you are viewing a subcircuit's state, the entire hierarchy is cleared.
Advances the simulation one step forward. For example, a signal may end up entering a gate during one step, but the gate won't show a different signal until the next simulation step. To help identify which points in the overall circuit have changed, any points whose values change are indicated with a blue circle; if a subcircuit contains any points that have changed in it (or its subcircuits, recursively), then it will be drawn with a blue outline.
When you delve into a

one displays the corresponding circuit.
If you have delved into a subcircuit's state and then moved back out, this submenu lists the subcircuits below the current circuit. Selecting one of the circuits displays the corresponding circuit.

THE HOUSE OF MIRTH A film review by Christopher Null Copyright 2000 filmcritic.com filmcritic.com
Draw near and bear witness to Gillian Anderson, a very successful television actress (The X Files) who is still trying to find her legs on the big screen. Like many before her, she will try a tactic that has made stars out of otherwise B-list actors: By taking the leading role in an art house flick.
Welcome then to The House of Mirth, a period piece which bears little happiness for those within. Or, ultimately, for those in the audience.
It is New York City in 1905, a town full of promise in an era of drawing rooms in which tea is still served every afternoon. On the fringe of society is Miss Lily Bart (Anderson), a brazen vixen who has yet to marry and wears red gowns to the symphony when everyone else has dressed down. She's a bit of a bad girl: She smokes, she skips church, and she's "on the hunt" for a husband. And her bad habits have spilt over into her social life.
She dallies with the lawyer Lawrence Selden (Eric Stoltz) in an apparent affair, but pities him because he actually has to work. Gus Trenor (Dan Aykroyd, in his best role in decades) also offers his affections, but, alas, he's married. And then there's Sim Rosedale (Anthony LaPaglia), a kind of Michael Milken for the Industrial Age. None present very good husband choices, which leads Miss Bart to take all kinds of measures to find a mate. Ultimately, through a falling out with her best friend Bertha (Laura Linney) -- for reasons which I still don't understand -- she finds her status in society plummeting, as Bertha singlehandedly engineers her descent -- off camera.
It's a worthy tale of blackmail and backstabbing, but unfortunately it is told in the traditional, corseted, Masterpiece Theatre manner that sadly leaves virtually all of this treachery (and the juiciness) behind the scenes. With a PG rating, there's nary a heaving bosom to behold and only one slap to the face to get your pulse going. One can only be thankful the film isn't narrated a la The Age of Innocence, a film with which The House of Mirth otherwise has much in common. (Both are based on Edith Wharton novels, and it's apparent the former was her better work.)
At the crux of the problem is director Terence Davies, who has structured the film with an unfortunate lack of foresight. A number of unnecessary scenes are loaded on, but this is not counterbalanced by much-needed explanatory scenes that have somehow gone missing. The ultimate effect is to make The House of Mirth a somber experience that drags on and on at a ponderous pace that would be far too slow if you didn't need the time to construct your own plot in its apparent absence.
Much has already been said of Anderson's aplomb with her role, but often the picture feels a bit like Stoltz and Anderson are reading for a play off-Broadway or in their backyard, their lines delivered in a manner that feels smarmy and disingenuous. Not for a second does Anderson look at home in period dress. But at the same time, she has a way of saying "delicious" that simply makes you melt. Overall, the decently apt cast is hardly stellar.
Which leaves us with the theme of our tale. As it turns out, The House of Mirth hasn't aged all that well since it was originally written, which would explain why it hasn't been made into a feature film since 1918. Put simply: Morality at the turn of the last century just doesn't translate well to morality at the turn of this one. Exactly how Miss Bart gets into her predicament is unclear, as Bertha has the worst reputation of the bunch. Why would anyone listen to her? Ultimately, I just didn't buy the story.
But in the end, Miss Bart's sad tale of woe is at least a bit universal. Like so many others, Miss Bart is a victim of her own na´vetÚ, stuck in a world where there truly are no good guys, and yet she relies on others for aid. (Stoltz's character is the closest we are given to a hero, and he's hardly a stand-up chap.) Can unsubstantiated gossip still sink a person? I suppose so, but who can imagine not fighting back?

HoloLens Mounting and Pepper Configuration Instructions
After software installation, the following steps are required to configure the system components in order to connect and function with each other.
Mount HoloLens on Pepper
The HoloLens device can be conveniently secured to the Pepper robot's head using adhesive velcro strips.
Assembly Steps: - First, access the Pepper's joint-release key which is stored under the rubber covering near the Emergency Power Off button behind the robot's neck:
-
Use the joint-release key to remove the access-cover on the back of the robot's head by inserting it into the two holes below the cover:
-
Make a head back strap with adhesive velcro by cutting 10-inch strips of both the hook and loop sides and sticking their adhesive sides together. Attach the strap by slipping it between the flexible fan housing and the head-cover support beam:
-
Affix a 2.5 inch and a 3.5 inch adhesive velcro loop pad to the top of the robot's head in the positions shown:
-
Set the HoloLens device over the robot's head and open the head-band adjust band all the way by rotating the knob all the way to the left:
-
Secure the back of the HoloLens device to the back of the robot's head by tightly creating a closed loop with the two-sided Velcro head strap.
-
Make a second mount strap by creating a 2.5 inch two-sided Velcro strip and securing it over the loop surface of both the HoloLens headstrap and rear mounting pad.
-
Make a third mount strap by creating a 3.5 inch two-sided Velcro strip and securing it over the loop surface of both the HoloLens headstrap and front mounting pad and bringing over the hook side of the HoloLens headstrap to the loop side of the same strap:
Pepper Configuration
Pepper qicli commands can be issued via the Choregraphe application or directly using a secure shell (SSH) terminal. The Pepper robot's IP address can be obtained by tapping the button on the front of the robot's torso and underneath the bottom edge of the tablet mounted on its chest. The address will be spoken by the robot. If a new wireless network needs to be configured, in some cases a wired ethernet connection must be made to the back of the robot's head. An embedded web server in the robot provides a management website at the robot's IP address.
Detailed documentation and further resources for the Pepper robot are on this website:

Pepper Naoqi Shell Commands
For reference, following are some example commands that can be ran on the Pepper robot over a secure shell session.
A complete listing of the NAOqi API is in the Pepper documentation here:
- https://developer.softbankrobotics.com/pepper-naoqi-25/naoqi-developer-guide/naoqi-apis
Wake Pepper up:
$ ssh nao@<pepper IP>
> qicli call ALMotion.wakeUp
Make Pepper go to sleep:
> qicli call ALMotion.rest
Shut down Pepper (The connection will close and further control will be lost until the robot is powered back up):
> sudo shutdown -h now
Get the joint names for the body or a chain:
> qicli call ALMotion.getBodyNames "Body"
View Pepper's current joint state:
> qicli call ALMotion.getSummary
Change Pepper's head pitch:
> qicli call ALMotion.setAngles "HeadPitch" 0.0 0.1
Note: setAngles is a non-blocking call with the following parameters: - names – The name or names of joints, chains, “Body”, “JointActuators”, “Joints” or “Actuators”. - angles – One or more angles in radians - fractionMaxSpeed – The fraction of maximum speed to use
Valid Pepper joint names can be found here and here, or call getBodyNames for a complete list.
Pepper RVIZ Configuration File
The configuration file for the Pepper robot will set up ROS nodes for convenient operations as well as present a simulated model of the robot on the navigation map.
Location: /opt/ros/melodic/share/naoqi_driver/share/pepper.rviz
Miscellaneous
The folowing instructions are optional and provide alternative methods to perfom setup and configuration actions. They are intended to be helpful in system modification and/or troubleshooting.
Enumerate network interfaces on Ubuntu:
The following IP commands can be used on the Navigation PC's console UI to expose values needed for configuration:
$ ip l show
$ ip a show eno1
Naoqi Command Sequence for Calibration Positions
As an alternative to the Dashboard UI, the console UI in the calibration window can be accessed via an SSH terminal to set the head angles directly. In these examples the first value indicates the joint motor, the second value indicates the angle to move to in radians and last value indicates the speed of movement in seconds.
- move Pepper's head into inital/default pose:
```
$ ssh nao@
qicli call ALMotion.setAngles "HeadPitch" 0.0 0.1
qicli call ALMotion.setAngles "HeadYaw" 0.0 0.1 ```
- press space bar to record the initial position
- move Pepper's head upward:
```
qicli call ALMotion.setAngles "HeadPitch" -0.35 0.1 ```
- press space bar again to record the new position
- reset Pepper's head pitch and then rotate to left:
```
qicli call ALMotion.setAngles "HeadPitch" 0.0 0.1
qicli call ALMotion.setAngles "HeadYaw" 0.7 0.1 ```
- press space bar again to record the new position
- rotate Pepper's head to the right:
```
qicli call ALMotion.setAngles "HeadYaw" -0.7 0.1 ```
- press space bar again to record the new position
- press "c" key to calibrate
- reset Pepper's head pitch and rotation:
```
qicli call ALMotion.setAngles "HeadPitch" 0.0 0.1
qicli call ALMotion.setAngles "HeadYaw" 0.0 0.1 ```

HoloLens Security Certificate Installation
Build PC
The connection that supports compiled software deployments between Microsoft Visual Studio running on the Build PC and the HoloLens device is secured with a PIN exchange during pairing as described above. However, the "certificate error" seen in the browser when accessing the HoloLens Device Portal can be fixed by creating a trust relationship with the device.
Each HoloLens generates a self-signed certificate for its SSL connection. By default, this certificate is not trusted by your PC's web browser and you may get a "certificate error". You can securely connect to your device by downloading this certificate from your HoloLens over USB or a Wi-Fi network you trust and trusting it on your PC.
- Make sure you are on a secure network (USB or a Wi-Fi network you trust).
- Download this device's certificate from the "Security" page on the Device Portal.
- Navigate to: https://
/devicepair.htm - Open the node for System > Preferences
- Scroll down to Device Security, select the "Download this device's certificate" button.
- Navigate to: https://
- Install the certificate in the "Trusted Root Certification Authorities" store on your PC.
- From the Windows menu, type: Manage Computer Certificates and start the applet.
- Expand the Trusted Root Certification Authority folder.
- Select the Certificates folder.
- From the Action menu, select: All Tasks > Import...
- Complete the Certificate Import Wizard, using the certificate file you downloaded from the Device Portal
- Restart the browser
Note: This certificate will only be trusted for this device and the user will have to go through the process again if the device is flashed.
Navigation PC
On the Navigation PC, certificates are required to enable secure communications when the Navigation PC initiates connections with the Pepper robot and the HoloLens device. Open the Device Portal in the web browser and HoloLens IP into the address bar:
-
Click on the security warning icon in the left end of the address bar:
-
In the call-out, click "Connection Not Secure", then "More Information" to open the Page Info menu screen and then click the "View Certificate" button:
-
In the Certificate's page, click the link to download the certificate PEM file:
-
Convert and intall the certificates:
$ sudo apt-get install ca-certificates -y $ openssl x509 -outform der -in certificate.pem -out certificate.crt $ sudo cp certificate.crt /usr/local/share/ca-certificates $ sudo update-ca-certificates
Change or Disable HoloLens Sleep Settings (Optional)
For convenience, it may be desired to change or even turn off the HoloLens device's sleep settings to enable prolonged navigation operations. Navigate to the Device Portal by using your HoloLens IP address in a web browser and log in with the username/password set above. - Navigate to Sleep Settings in the System->Preferences - To disable, right-click on the drop-down selector box for the sleep time-out value and select "Inspect". - add "0" as a list option, which will translate to never - select the new list option "0"
Note: This will need to be performed twice to disable sleep for both "battery" and "plugged-in" settings.

Abstract: We present an integrated probabilistic model for layered object tracking that combines dynamics on implicit shape representations, topologicalshape constraints, adaptive appearance models, and layered flow. The generative model combines the evolution of appearances and layer shapes with a Gaussian process flow and explicit layer ordering. Efficient MCMC sampling algorithms are developed to enable a particle filtering approach while reasoning about the distribution of object boundaries in video. We demonstrate the utility oftheproposed tracking algorithm on a wide variety of video sources while achieving state-of-the-art results on a boundary-accurate tracking dataset.


In this introduction, we’ll provide a step-by-step guide to training models with AWS Sagemaker using the sagemaker R package.
We are going to train and tune an xgboost regression model on the sagemaker::abalone
dataset, analyze the hyperparameters, and make new predictions.
The tuning interface is similar to the caret package. We’ll
choose a model
define a hyperparameter grid
set the training and validation data
I’ll be building a regression model on the built-in abalone dataset, taken from UCI dataset database.

The built-in hyperparameter tuning methods with AWS Sagemaker requires a train/validation split. Cross-validation is not supported out of the box.
We can quickly split the data with rsample:
abalone_split <- rsample::initial_split(sagemaker::abalone)
The training data needs to be uploaded to an S3 bucket that AWS Sagemaker has read/write permission to. For the typical AWS Sagemaker role, this could be any bucket with sagemaker
included in the name.
We’ll use the sagemaker::write_s3
helper to upload tibbles or data.frame
s to S3 as a csv.
write_s3(analysis(abalone_split), s3(s3_bucket(), "abalone-train.csv"))
write_s3(assessment(abalone_split), s3(s3_bucket(), "abalone-test.csv"))
You can also set a default bucket with options(sagemaker.default.bucket = "bucket_name")
for sagemaker::s3_bucket
.
Then we’ll save the paths to use in tuning:
Now we’ll define ranges to tune over:
ranges <- list(
max_depth = sagemaker_integer(3, 20),
colsample_bytree = sagemaker_continuous(0, 1),
subsample = sagemaker_continuous(0, 1)
)
Then we kick off the training jobs.
tune <- sagemaker_hyperparameter_tuner(
sagemaker_xgb_estimator(), split, ranges, max_jobs = 10
)
We can get more details about the tuning jobs by looking at the logs:
logs <- sagemaker_tuning_job_logs(tune)
logs %>%
glimpse()
#> Rows: 10
#> Columns: 9
#> $ final_objective_value <dbl> 2.22218, 2.28891, 2.27633, 2.30395, 2.1…

#> $ subsample <dbl> 0.93328062, 0.33505527, 0.90047042, 0.0…
From here, we can investigate the training deeper:
logs %>%
select(final_objective_value, colsample_bytree:subsample) %>%
pivot_longer(colsample_bytree:subsample) %>%
ggplot(aes(value, final_objective_value)) +
geom_point() +
facet_wrap(~name, scales = "free_x")
We can also see the individual jobs logs, to track the difference between the train/validation set. This might be useful for advanced model tuning.
Note that tune$model_name
is the name of the best model found during training.
job_logs <- sagemaker_training_job_logs(tune$model_name)

pivot_longer(`train:rmse`:`validation:rmse`) %>%
ggplot(aes(iteration, value, color = name)) +
geom_line()
The AWS Sagemaker API supports two predictions modes: real-time endpoint and batch inference.
Real-time opens a persistent web-endpoint for predictions. Deploying takes a few minutes.
Then make new predictions on tibbles or data.frame
s, using the standard predict
generic.
pred <- predict(tune, sagemaker::abalone[1:100, -1])
glimpse(pred)
#> Rows: 100
#> Columns: 1
#> $ .pred <dbl> 10.257903, 8.102968, 10.027587, 9.213963, 6.185315, 7.296525, 1…
Once deployed, the endpoint has a subsecond latency.
Make sure to delete the endpoint when you are done to avoid charges.
You can also make batch predictions from data saved in S3. The batch method will write the predictions as a csv in an S3 folder.
s3_output_path <- batch_predict(
tune,
s3_input = s3(s3_bucket(), "abalone-inference.csv"),
s3_output = s3(s3_bucket(), "abalone_predictions")
)
We can use the sagemaker::read_s3
method to easily read csv data from S3.


Snail creeps up the vertical pole of height H feets. Each day it goes A feets up, and each night it goes B feets down. On which day will the snail reach the top of the pole?
Input data format: On the input the program receives non-negative integers H, A, B, where H > B and A > B. Every integer does not exceed 100.


i managed to acquire some 5 mg dextroamphetamine tablets from a kid in my form who's brother is A.D.D. it was the weekend coming up and my parents were going away on holiday leaving me the house for friday, saturday, sunday and monday ;) i went to school friday and scored 10 pills for $20 aus. i had to walk home after school and i pretty much power walked all the way home i was that amped to go a couple of rails. i got home and chopped up half a pill and railed it straight up. i didnt really notice the effects greatly, so i railed another 1/4 pill an hour later. this got me going, and i was in a great mood and had quite a nice amount of energy. nothing too drastic and nothing in comparison to the speed i had the weekend before. i bounced around the house that afternoon doing chores and shit that would normally bore me shitless, then i went out to my mates.
when i got there everyone was rather quiet and drinking their alcohol while i was rather talkative and happy. i had a great amount of energy, and was amped to do something other than sit around bored. while waiting for them to get pissed i downed half a pill orally and waited for its effects. we got a video camera and headed into town. we bombed the town with stickers of a skate shop, and generally just had a good time. i didnt really notice the oral dose come on, it rather extended and slightly intensified what i was already feeling. i found that i could jump higher than normal, may have just been an illusion though. so anyway we head back to my mates and just sat around before everyone felt like going to bed. it was 2:00 in the morning and i was still feeling pretty awake.
i got on my bike and rode home slowly, noticing that my vision was a lot clearer and i could see a lot easier in the dark. i got home and did some more cleaning and shit before going to bed at around 3:30. i found it pretty easy to fall asleep and had a good sleep too. when i awoke i was feeling good and not drained, so i went and chopped up half a pill and railed it about 30 mins after i got up. i went and had a shower and was feeling pretty good about life and was in a positive mindframe. i then watched some 'up in smoke', but my television wasnít loud enough and it was pissing me off so i hooked it up to the stereo and cranked it. i was so damn amped it wasnít funny. i was having a great time, and decided i should go another half. so i did another half and bounced around to up in smoke in my boxers for pretty much the rest of the day. i didnít really eat a great deal that day but i had plenty of energy.
i then had another shower as i had been sweating all day and went to my friends house again. i decided to do another 1/4 of a pill nasally before i left and took another 3/4 with me pre-chopped. i got to my friends and they were all drinking alcohol again, already on their ways to being pissed, while i was just bouncing around in a great mood. then we got the idea to go to the movies so we headed out and watched planet of the apes. we bought our tickets and headed into the cinema. when we got in there they pulled out there piss and continued to drink. i was going to do my 3/4 that i brought with me, but they wanted some of it, so we all headed to the toilets and i split it into 3 lines and we all had some. we headed back into the movies and sat down. i had a sick time, it was a fucken mad movie, and i can remember it really good. i understood every bit of the movie and it all came together in my head.
after the movie we were all amped, and it seemed as though they were getting effect of like a 1/4 pill, as they were very energetic and going into the movie they were quite sedated. we went back and grabbed the camera before heading back into town to do some fun shit. we just did the same as night before but cained a few wheelie bins and porta toilet before heading back for some bongs. everyone had one and then they all passed out. i was about to head home and then it started raining. i was pretty angry about it, coz i didnít want to go to sleep and i wanted to get some munchies at home, but i ended up cribbing at his house.
i woke up in the morning in a great mood and went to red rooster for some food. the rest of the day i just mellowed at home and remembered the weekend that was. i was pretty amped for some more, but i wanted to save my last pills for my exams coming up ;) hahah
i recommend this shit to anyone. a great amphetamine that has nice effects at low doses. will try a higher dosage next time i can score some.
effects roundup:
i noticed a slight increase in heart rate (didnít want to focus too much on it, as i have tripped out more than once on the speed of my heart on drugs =] lol) but nothing too major. when the drug was still in effect i was always in a good mood, but when it started to wear off i was a bit edgy. thoughts were always flowing through my mind, and found it very easy to express myself and put forth my ideas. i was very creative in my wording and i seemed more intellectual than normal. i never had any problems on my dose, and while althought small, i did notice the effects. them consisting mainly of energy, mood lift, clearer thoughts, increase in heart rate/shallower respiration, and a greater understanding of life at the time. i managed to do multiple chores at once and keep new ones fresh in my mind, and i did a fair amount of housework in a shorter time than normal.
ps: if anyone knows how I can filter any of the fillers and junk out of the dexedrine tablets so i am not snorting anything other than the amphetamine, would you please email me at<EMAIL_ADDRESS>thankyou.
congratulations if you made it this far lol ;)

couchbase
Couchbase is a NoSQL document database with a distributed architecture for performance, scalability, and availability. It enables developers to build applications easier and faster by leveraging the power of SQL with the flexibility of JSON.
This module provides couchbase access via Java SDK
dependency
<dependency>
<groupId>org.jooby</groupId>
<artifactId>jooby-couchbase</artifactId>
<version>1.6.6</version>
</dependency>
exports
CouchbaseEnvironment
CouchbaseCluster
AsyncBucket
Bucket
AsyncDatastore
Datastore
AsyncRepository
Repository
- Optionally a couchbase
Session.Store
usage
Via couchbase connection string:
{
use(new Couchbase("couchbase://locahost/beers"));
get("/", req -> {
Bucket beers = require(Bucket.class);
// do with beer bucket
});
}
Via property:
{
use(new Couchbase("db"));
get("/", req -> {
Bucket beers = require(Bucket.class);
// do with beer bucket
});
}
The db
property is defined in the application.conf
file as a couchbase connection string.
create, read, update and delete
Jooby provides a more flexible, easy to use and powerful CRUD operations via AsyncDatastore/AsyncDatastore objects.
import org.jooby.couchbase.Couchbase;
import org.jooby.couchbase.N1Q;
...
{
use(new Couchbase("couchbase://localhost/beers"));
use("/api/beers")
/**
* List beers
*/
.get(req -> {
Datastore ds = require(Datastore.class);
return ds.query(N1Q.from(Beer.class));
})
/**
* Create a new beer
*/
.post(req -> {
Datastore ds = require(Datastore.class);
Beer beer = req.body().to(Beer.class);
return ds.upsert(beer);
})
/**
* Get a beer by ID
*/
.get(":id", req -> {
Datastore ds = require(Datastore.class);
return ds.get(Beer.class, req.param("id").value());
})
/**
* Delete a beer by ID
*/
.delete(":id", req -> {
Datastore ds = require(Datastore.class);
return ds.delete(Beer.class, req.param("id").value());
});
}
As you can see benefits over AsyncRepository
/Repository
are clear: you don’t have to deal with EntityDocument
just send or retrieve POJOs.
Another good reason is that AsyncDatastore/AsyncDatastore supports query operations with POJOs too.
design and implementation choices
The AsyncDatastore/AsyncDatastore simplifies a lot the integration between Couchbase and POJOs. This section describes how IDs are persisted and how mapping works.
A document persisted by an AsyncDatastore/AsyncDatastore looks like:
{
"model.Beer::1": {
"name": "IPA",
...
"id": 1,
"_class": "model.Beer"
}
}
The couchbase document ID contains the fully qualified name of the class, plus ::
plus the entity/business ID: mode.Beer::1
.
The business ID is part of the document, here the business ID is: id:1
. The business ID is required while creating POJO from couchbase queries.
Finally, a _class
attribute is also part of the document. It contains the fully qualified name of the class and its required while creating POJO from couchbase queries.
mapping pojos
Mapping between document/POJOs is done internally with a custom EntityConverter
. The EntityConverter
uses an internal copy of ObjectMapper
object from Jackson. So in theory anything that can be handle by Jackson will work.
In order to work with a POJO, you must defined an ID. There are two options:
- Add an
id
field to your POJO:
public class Beer {
private String id;
}
- Use a business name (not necessarily id) and add
Id
annotation:
import import com.couchbase.client.java.repository.annotation.Id;
...
public class Beer {
@Id
private String beerId;
}
Auto-increment IDs are supported via GeneratedValue:
public class Beer {
private Long id;
}
Auto-increment IDs are generated using {@link Bucket#counter(String, long, long)} function and they must be Long
. We use the POJO fully qualified name as counter ID.
Any other field will be mapped too, you don’t need to annotate an attribute with {@link Field}. If you don’t want to persist an attribute, just ad the transient
Java modifier:
public class Beer {
private String id;
private transient ignored;
}
Keep in mind that if you annotated your POJO with Jackson annotations they will be ignored… because we use an internal copy of Jackson that comes with Java Couchbase SDK
reactive usage
Couchbase SDK allows two programming model: blocking
and reactive
. We already see how to use the blocking API, now is time to see how to use the reactive
API:
{
use(new Couchbase("couchbase://localhost/beers"));
get("/", req -> {
AsyncBucket bucket = require(AsyncBucket.class);
// do with async bucket ;)
});
}
Now, what to do with Observables? Do we have to block? Not necessarily if we use the Rx module:
...
import org.jooby.rx.Rx;
...
{
// handle observable route responses
use(new Rx());
use(new Couchbase("couchbase://localhost/beers"));
get("/api/beer/:id", req -> {
AsyncDatastore ds = require(AsyncDatastore.class);
String id = req.param("id").value();
Observable<Beer> beer = ds.get(Beer.class, id);
return beer;
});
}
The Rx module deal with observables so you can safely return Observable
from routes (Jooby rocks!).
multiple buckets
If for any reason your application requires more than 1 bucket… then:
{
use(new Couchbase("couchbase://localhost/beers")
.buckets("extra-bucket"));
get("/", req -> {
Bucket bucket = require("beers", Bucket.class);
Bucket extra = require("extra-bucket", Bucket.class);
});
}
Easy, right? Same principle apply for Async* objects
multiple clusters
Again, if for any reason your application requires multiple clusters… then:
{
CouchbaseEnvironment env = ...;
use(new Couchbase("couchbase://<IP_ADDRESS>")
.environment(env));
use(new Couchbase("couchbase://<IP_ADDRESS>")
.environment(env));
}
You must shared the CouchbaseEnvironment
as documented here.
options
bucket password
You can set a global bucket password via: couchbase.bucket.password
property, or local bucket password (per bucket) via couchbase.bucket.[name].password
property.
environment configuration
Environment configuration is available via: couchbase.env
namespace, here is an example on how to setup kvEndpoints
:
couchbase.env.kvEndpoints = 3
cluster manager
A ClusterManager
service is available is you set an cluster username and password:
couchbase.cluster.username = foo
couchbase.cluster.password = bar
couchbase.conf
These are the default properties for couchbase:
# configure the environment by adding properties to the `couchbase.env` namespace, like:
# couchbase.env.kvEndpoints = 2
# Some custom error codes
err {
com.couchbase.client.java.error.BucketAlreadyExistsException = 400
com.couchbase.client.java.error.BucketDoesNotExistException = 404
com.couchbase.client.java.error.DocumentAlreadyExistsException = 400
com.couchbase.client.java.error.DocumentDoesNotExistException = 404
com.couchbase.client.java.error.QueryExecutionException = 400
}
couchbase session store
A Session.Store powered by Couchbase.
dependency
<dependency>
<groupId>org.jooby</groupId>
<artifactId>jooby-couchbase</artifactId>
<version>1.6.6</version>
</dependency>
usage
{
use(new Couchbase("couchbase://localhost/bucket"));
session(CouchbaseSessionStore.class);
get("/", req -> {
Session session = req.session();
session.put("foo", "bar");
..
});
}
Session data is persisted in Couchbase and document looks like:
{ "session::{SESSION_ID}": { "foo": "bar" } }
options
timeout
By default, a session will expire after 30 minutes
. Changing the default timeout is as simple as:
# 8 hours
session.timeout = 8h
# 15 seconds
session.timeout = 15
# 120 minutes
session.timeout = 120m
Expiration is done via Couchbase expiry/ttl option.
If no timeout is required, use -1
.
custom bucket
The session document are persisted in the application/default bucket, if you need/want a different bucket then use {@link Couchbase#sessionBucket(String)}, like:
{
use(
new Couchbase("couchbase://localhost/myapp")
.sessionBucket("session")
);
}

Privacy Levels¶
Read the Docs supports 3 different privacy levels on 2 different objects; Public, Protected, Private on Projects and Versions.
Understanding the Privacy Levels¶
| Level | Detail | Listing | Search | Viewing |
|---|---|---|---|---|
| Private | No | No | No | Yes |
| Protected | Yes | No | No | Yes |
| Public | Yes | Yes | Yes | Yes |
Note
With a URL to view the actual documentation, even private docs are viewable. This is because our architecture doesn’t do any logic on documentation display, to increase availability.
Public¶
This is the easiest and most obvious. It is also the default. It means that everything is available to be seen by everyone.
Protected¶
Protected means that your object won’t show up in Listing Pages, but Detail pages still work. For example, a Project that is Protected will not show on the homepage Recently Updated list, however, if you link directly to the project, you will get a 200 and the page will display.
Protected Versions are similar, they won’t show up in your version listings, but will be available once linked to.
Private¶
Private objects are available only to people who have permissions to see them. They will not display on any list view, and will 404 when you link them to others.

STAR WARS: EPISODE I - THE PHANTOM MENACE A film review by David N. Butterworth Copyright 1999 David N. Butterworth
**1/2 (out of ****)
It was an overcast, muggy Tuesday afternoon, the day before the eagerly-awaited "Star Wars" prequel was slated to blast into theaters. I walked up to the bored-looking ticket seller at my local multiplex (twenty-four screens to be precise) and asked "So what's the deal with "Star Wars" tickets?" Anticipating a long, drawn-out answer about nothing being available until the 27th and having to wait "over there," the lethargic teenager simply asked me what show I wanted to see. "When's the first one?" I asked. "10am." "And you still have tickets?" "Yes." "Then I'll take one for the ten o'clock show please."
Hmm... No hoopla. No lines. I didn't even have to camp out!
At 9:30am the next morning the parking lot was already pretty full, and you can bet people weren't there for the new Jet Li movie. The ticket taker told me to hang onto my stub at all times, and to sit as close to the middle as possible, as the show was sold out. For a sold-out show there were a lot of empty seats, but by that point all I could think about was my hankering for some gummi sourpatch nightcrawlers.
If you go to see "Star Wars: Episode I - The Phantom Menace," as it's correctly called (and I suspect you will), I recommend you get there early. Not just in case your particular show happens to be sold out too, but to listen to "Star Wars" junkies complaining about this, that, and the other. My favorite comment came halfway through the film when some numskull whispered reverentially "Shmi Skywalker's the Virgin Mary!"
I saw the original "Star Wars" back in 1977 when it first came out. A lot of hoopla surrounded it at the time and for the most part it was deserving. The special effects were light-years ahead of their time and the story was a classic case of good vs. evil, beautifully realized, and inspired by Akira Kurosawa's "The Hidden Fortress."
That blast from the brass section as the "Star Wars" insignia appears from out of nowhere and slowly pushes its way into the starry screen still gives me goosebumps.
A little context for you. Although I can't tell a bantha from a Grand Moff Tarkin, I do believe that Harrison Ford can't act his way out of a brown paper bag. I believe that Mark Hamill didn't even try. I believe that Carrie Fisher is a better novelist than she is an actor, I believe that Chewbacca was the series' best character and they should have brought him back for "Episode I," and I believe that the Ewoks were a big mistake (their TV series spin-off an even bigger one). I believe in the twin moons of Tatooine, the golden orbs of Unrath, the curve of Natalie Portman's back, and I believe in long, slow, deep, soft, wet kisses that last three days...
But getting back to "The Phantom Menace." What did I think of it?
It's okay.
We've been so deluged by special effects-laden movies in the 1990s that we take a lot of today's technical wizardry for granted. The new "Star Wars" film is purported to contain some 2,000 "effects shots" (compared to the 800 or so in "Titanic"), the most in any one movie, but all that stuff seems like overkill at times. We miss what we're supposed to be looking at because there's just too much of it. "Star Wars" did exponential things with technology. Relatively speaking, "The Phantom Menace" would have required special footwear, probably, to have had the same impact.
Nevertheless there are some glorious paintings, models, and backdrops in the film. These cities and civilizations really come alive. The craftsmanship is top-notch, state-of-the-art, exquisite. The costumes, not to mention Natalie Portman's hairdos (she plays Queen Amidala of Naboo) are breathtaking. That's right, breathtaking hairdos.  Terence Stamp is barely in the film. The baddie, Darth Maul, is appropriately named because he looks like some WWF spokesperson in a monk's habit. He's pretty cool.
On the other hand, the Federation's computer-animated droids can't hold a light saber to those imperial storm troopers. Ewan McGregor (as Obi-Wan Kenobi) is as stiff as a post and I hate to say it but the film actually gets a bit boring at times. The need to explain connections to the original trilogy results in a lot of talky sequences and deja-vu, some of it welcome and some of it not. Jar Jar Binks, a walking, wisecracking Rasta duck-billed platypus whose catchphrase is "How rude!" provides much of the comic interest but after a while he tends to blend in with the rest of the lop-eared platypi.
One of the film's big set pieces is a "pod race" featuring the young, fatherless Anakin (Jake Lloyd), an homage to "Ben Hur"'s famous chariot race. The point of all this spectacle is so that Jedi master Qui-Gon Jinn (Liam Neeson) can win a bet to pay a winged muppet called Watto for spare parts to fix a crippled spaceship. I know Jedi knights must have some code of ethics but couldn't they have found an easier solution to their problem (like, maybe, steal the hardware, or at least borrow it?). Similarly, part of the deal is to have the enslaved future Chosen One freed but unfortunately our heroes are forced to leave the boy's mother behind. "I tried to win her freedom but Watto wasn't having any of it," says Neeson's character, or words to that effect. Sounds rather pathetic from a Jedi, doesn't it? "I wanted to kill Darth Vader, but when I got to the Death Star, he wasn't home." Puleez.
The dialogue and plot elements aren't the reason to see the film, of course. You expect the general good-guys-have-to-stop-the-bad-guys scenario (here, taxation plays a key role). It's all those brave new worlds, intergalactic shoot-'em-ups, strange reptilian and mechanical creatures, and characters with funny names you can either cheer or hiss, that matters.
And "The Phantom Menace" has got 'em by the score.  Let's just hope that Episodes II and III spend a little more time on character development, that's all.

Tips for creating good Object Classes:
Object classes are things we wish to collect information about.
Good names for object classes are short, descriptive nouns.
Be generic:An object class should apply to the widest group possible.
Only make more specific classes, if there are particular attributes only found on the specialisation.
e.g. Person, not Australian Citizens
Use singlar forms:When discusing individuals, use singular terms to ensure unambiguity. For example, a Person can have an age, but a Group of people has an average age.

Hyundai Nexo: first hydrogen car certified for Australia, now for the refuelling stations
Australians are one step closer to being able to buy a car that emits only water vapour from its tailpipe. Now we’re waiting for the hydrogen superhighway.
by Joshua Dowling- shares
The car that emits only water vapour from its tailpipe – the Hyundai Nexo hydrogen-powered vehicle – is officially ready for Australian roads.
The electric car that runs on hydrogen has been formally certified by the Australian government, cleared for use on local roads, and scored top marks in the latest crash safety tests.
The Hyundai Nexo will be on sale from next year but initially will only be available on lease to governments or fleets that have access to a hydrogen refilling station.
The Australian Capital Territory is poised to take delivery of the first of 20 Hyundai Nexo “fuel cell” cars early next year once the installation of its hydrogen refuelling station is complete.
The Queensland Government will add five Hyundai Nexo cars once its hydrogen station in Brisbane is operational by the middle of 2020.
Toyota in partnership with the Victorian Government will open a hydrogen refueller in Melbourne by the end of 2020.
Hyundai says hydrogen stations in South Australia, West Australia and Tasmania are due to follow but are yet to be announced.
For now there are no hydrogen refuellers locked in for the nation's biggest population centre, although there are preliminary discussions about an installation in western Sydney.
To date, the only hydrogen refuelling point in Australia is behind Hyundai’s Sydney head office for its use only. Toyota Australia has a hydrogen refueller on the back of a truck so it can test its small fleet of fuel cell cars in remote areas.
“The future is now,” said Scott Nargar, Hyundai’s senior manager for future mobility and government relations. “We really need infrastructure on the forecourts of service stations, we need infrastructure in shopping centres, we need infrastructure in the home.”
The Hyundai executive said “the transition is starting to happen, it’s just a matter of catching up with what’s happening in Europe and North America”.
“Our vehicles are on the roads here now,” said Mr Nargar. “Our fuel cell vehicle is certified and we’re ready to start selling it, leasing it, we’re just waiting for the infrastructure to catch up.”
He said it was time for governments to “consider the technology that’s coming in from ourselves and some of our competitors. We need to work together”.
Hydrogen-powered cars have the advantage of being refuelled in about five minutes, a similar amount of time to refuelling a petrol car.
The hydrogen powers what is best described as a built-in power station – or fuel cell – that creates electricity that, in turn, charges an onboard battery pack which runs the vehicle’s electric motor.
The advantage is that it doesn’t take as long as an electric car to refuel from empty. The downside is that hydrogen refuelling stations are scarce and the fuel is more volatile to transport.
To hedge its bets, Hyundai says it has all four options covered: petrol-electric hybrid, plug-in hybrid, pure electric, and hydrogen power.
“No matter what the automotive landscape may look like in the future we are confident we will have a solution that will suit our customers’ needs,” said Mr Nargar.

The children of today are gearing up to become adult citizens of tomorrow. The growth is parallel to the future of our country, reflected through quality of the present education system. A school must stimulate curiosity in the young, impressionable minds and equip them with tools to be better human beings.
It is widely accepted that the learning process is instrumental in shaping ones personality and the way he/she deals with situations of life. The shift of thoughts from bookish knowledge to knowledge of life, in schools, has brought forth a sea of change. People have warmed up to the idea of education being the key to a well-rounded development instead of just a mean to acquire degrees and monetary success in life. Education must facilitate the cultivation of a healthy thought process and groom our cognitive abilities. In the present competitive world, education is a basic necessity for human beings after food, clothes and shelter.
School education must focus on the following aspects, which contribute immensely to the development of the young minds as they step into adulthood.
