The ElasticSearch plugin provides an ORM-like abstraction on top of elasticsearch. The plugin provides features that make testing, indexing documents and searching your indexes easier.
To install the ElasticSearch plugin, you can use composer
. From your
application’s ROOT directory (where composer.json file is located) run the
following:
php composer.phar require cakephp/elastic-search "@stable"
You will need to add the following line to your application’s config/bootstrap.php file:
Plugin::load('Cake/ElasticSearch', ['bootstrap' => true]);
Additionally, you will need to configure the ‘elastic’ datasource connection in your config/app.php file. An example configuration would be:
// in config/app.php
'Datasources' => [
// other datasources
'elastic' => [
'className' => 'Cake\ElasticSearch\Datasource\Connection',
'driver' => 'Cake\ElasticSearch\Datasource\Connection',
'host' => '<IP_ADDRESS>',
'port' => 9200,
'index' => 'my_apps_index',
],
]
The ElasticSearch plugin makes it easier to interact with an elasticsearch index
and provides an interface similar to the Database Access & ORM. To get started you should
create a Type
object. Type
objects are the “Repository” or table-like
class in elasticsearch:
// in src/Model/Type/ArticlesType.php
namespace App\Model\Type;
use Cake\ElasticSearch\Type;
class ArticlesType extends Type
{
}
You can then use your type class in your controllers:
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
// Load the Type using the 'Elastic' provider.
$this->loadModel('Articles', 'Elastic');
}
public function add()
{
$article = $this->Articles->newEntity();
if ($this->request->is('post')) {
$article = $this->Articles->patchEntity($article, $this->request->getData());
if ($this->Articles->save($article)) {
$this->Flash->success('It saved');
}
}
$this->set(compact('article'));
}
We would also need to create a basic view for our indexed articles:
// in src/Template/Articles/add.ctp
<?= $this->Form->create($article) ?>
<?= $this->Form->control('title') ?>
<?= $this->Form->control('body') ?>
<?= $this->Form->button('Save') ?>
<?= $this->Form->end() ?>
You should now be able to submit the form and have a new document added to elasticsearch.
Like the ORM, the Elasticsearch ODM uses Entities-like classes. The
base class you should inherit from is Cake\ElasticSearch\Document
. Document
classes are found in the Model\Document
namespace in your application or
plugin:
namespace App\Model\Document;
use Cake\ElasticSearch\Document;
class Article extends Document
{
}
Outside of constructor logic that makes Documents work with data from
elasticsearch, the interface and functionality provided by Document
are the
same as those in Entities
After you’ve indexed some documents you will want to search through them. The ElasticSearch plugin provides a query builder that allows you to build search queries:
$query = $this->Articles->find()
->where([
'title' => 'special',
'or' => [
'tags in' => ['cake', 'php'],
'tags not in' => ['c#', 'java']
]
]);
foreach ($query as $article) {
echo $article->title;
}
You can use the FilterBuilder
to add filtering conditions:
$query->where(function ($builder) {
return $builder->and(
$builder->gt('views', 99),
$builder->term('author.name', 'sally')
);
});
The FilterBuilder source has the complete list of methods with examples for many commonly used methods.
Like the ORM, the ElasticSearch plugin lets you validate data when marshalling documents. Validating request data, and applying application rules works the same as it does with the relational ORM. See the Validating Data Before Building Entities and Applying Application Rules sections for more information.
When you’re ready to index some data into elasticsearch, you’ll first need to
convert your data into a Document
that can be indexed:
$article = $this->Articles->newEntity($data);
if ($this->Articles->save($article)) {
// Document was indexed
}
When marshalling a document, you can specify which embedded documents you wish
to marshall using the associated
key:
$article = $this->Articles->newEntity($data, ['associated' => ['Comments']]);
Saving a document will trigger the following events:
Model.beforeSave
- Fired before the document is saved. You can prevent the
save operation from happening by stopping this event.Model.buildRules
- Fired when the rules checker is built for the first
time.Model.afterSave
- Fired after the document is saved.Note
There are no events for embedded documents, as the parent document and all of its embedded documents are saved as one operation.
When you need to re-index data, you can patch existing entities and re-save them:
$query = $this->Articles->find()->where(['user.name' => 'jill']);
foreach ($query as $doc) {
$doc->set($newProperties);
$this->Articles->save($doc);
}
After retrieving a document you can delete it:
$doc = $this->Articles->get($id);
$this->Articles->delete($doc);
You can also delete documents matching specific conditions:
$this->Articles->deleteAll(['user.name' => 'bob']);
By defining embedded documents, you can attach entity classes to specific
property paths in your documents. This allows you to provide custom behavior to
the documents within a parent document. For example, you may want the comments
embedded in an article to have specific application specific methods. You can
use embedOne
and embedMany
to define embedded documents:
// in src/Model/Type/ArticlesType.php
namespace App\Model\Type;
use Cake\ElasticSearch\Type;
class ArticlesType extends Type
{
public function initialize()
{
$this->embedOne('User');
$this->embedMany('Comments', [
'entityClass' => 'MyComment'
]);
}
}
The above would create two embedded documents on the Article
document. The
User
embed will convert the user
property to instances of
App\Model\Document\User
. To get the Comments embed to use a class name
that does not match the property name, we can use the entityClass
option to
configure a custom class name.
Once we’ve setup our embedded documents, the results of find()
and get()
will return objects with the correct embedded document classes:
$article = $this->Articles->get($id);
// Instance of App\Model\Document\User
$article->user;
// Array of App\Model\Document\Comment instances
$article->comments;
Like the ORM, the ElasticSearch plugin provides a factory/registry for getting
Type
instances:
use Cake\ElasticSearch\TypeRegistry;
$articles = TypeRegistry::get('Articles');
During test cases you may want to flush the registry. Doing so is often useful when you are using mock objects, or modifying a type’s dependencies:
TypeRegistry::flush();
The ElasticSearch plugin provides seamless test suite integration. Just like database fixtures, you can create test fixtures for elasticsearch. We could define a test fixture for our Articles type with the following:
namespace App\Test\Fixture;
use Cake\ElasticSearch\TestSuite\TestFixture;
/**
* Articles fixture
*/
class ArticlesFixture extends TestFixture
{
/**
* The table/type for this fixture.
*
* @var string
*/
public $table = 'articles';
/**
* The mapping data.
*
* @var array
*/
public $schema = [
'id' => ['type' => 'integer'],
'user' => [
'type' => 'nested',
'properties' => [
'username' => ['type' => 'string'],
]
]
'title' => ['type' => 'string'],
'body' => ['type' => 'string'],
];
public $records = [
[
'user' => [
'username' => 'billy'
],
'title' => 'First Post',
'body' => 'Some content'
]
];
}
The schema
property uses the native elasticsearch mapping format.
You can safely omit the type name and top level properties
key. Once your
fixtures are created you can use them in your test cases by including them in
your test’s fixtures
properties:
public $fixtures = ['app.articles'];

Lactuca - L. virosa, Cannabis & Alcohol
After reading on the 'net' about wild letuce I got me 50 grams for 9 euro at my local smartshop. After a some beers and weed joints I decided to test it. I rolled a small weed joint (normal rizla blue) with .25 gram lactuca added. It got me a bit less emotional. A nerve pain in my neck started to dissolve within 25 seconds after the first drag! It was gone after the joint. Nice results.
I repeated the same after an hour, but this time in bed. I got a feeling of wanting to lay down and close my eyes, but I resisted until I finnished the joint. Laying down and closing my eyes I 'melted' straight in to a dream. I awoke 6-7 hrs later fully rested after some wild dreams.
lactuca virosa is now part of my herbal use. It make's me sleep for exact 6.5 hr with he nicest of dreams!

For modern browsers which support tabs, each tab might be a separate browser process. If a Java applet is embedded in a browser page and the next generation plugin is being used, usually the process associated with the browser tab creates a JVM within the process (browser VM). The browser VM will create another JVM process (client VM) which will run the applet and manage the applet's life cycle. The client VM is a Java process (java.exe
on Windows and java
on Oracle Solaris/Linux platforms).
The following are some problems with Applets and troubleshooting techniques.
If your applet does not start, make sure to enable tracing and the Java console as explained previously. Then use hits below to find reason why applet does not work.
Do you get a trace file generated or see the Java console?
No, I don't get a trace file
Check if Java technology is detected, see
Yes
Look at JVM browser issues from
No
It is likely to be a configuration issue. See for common configuration problems and if it does not help, look at JVM browser issues from
Yes, I have a trace file
It is unlikely to be a configuration issue (unless you have the new generation plugin disabled). The problem is likely to be specific to this applet. Try to launch some other applets to confirm. Look at JVM client issues from
A crash could be caused by a platform or application issue.
Typically, if a crash happens in the JVM then there should be hs_err_*log file created in the current working directory (on Windows it is often placed on the desktop). It is the same crash report file as for standalone applications. For details about the report file, see Appendix A.
If you can spot native libraries loaded from the deployment cache directory, especially if you see code from these libraries in the crash stack, it is very likely to be a bug in the application.
Otherwise it is a JRE bug and needs to be reported to Bug Database.
The following are two scenarios to consider for a crash by platform or application issue.
JVM browser issues: Get more details about a JVM running in the browser process. Set the following two environment variables before starting the browser:
JPI_PLUGIN2_DEBUG=1 JPI_PLUGIN2_VERBOSE=1
On Windows, there should be a command window associated with the browser process. All browser VM debug output goes into the command window. Check to see if any exceptions are visible there. A Java thread dump can be obtained by using the Control+Break key sequence on the command window.
On Oracle Solaris or Linux platforms, after setting the above variables, start the browser from the same session. All browser VM debug output goes into the terminal window. To get a Java thread dump, on a separate terminal, use kill -3
pid or kill -SIGQUIT
pid, where pid is the process id of the browser process.
There are "heartbeat" messages sent between the client VM and browser VM. The "heartbeat" messages can be turned off by setting the JPI_PLUGIN2_NO_HEARTBEAT
environment variable to 1
. This will help isolate whether the problem is related to the "heartbeat".
If the log is not opening and environment variables are set in the browser process, then it is likely that the JRE is not installed correctly or Java is disabled. Check for configuration errors and try to reinstall the JRE if nothing else helps.
JVM client issues: Check the latest trace file for ideas.
Note: The same client JVM may be shared between multiple applets. Sometimes intermittent failures happen because the shared JVM does not have enough resources available (for example, heap size). In that case, a page reload often helps to resolve the problem.
If application fails with an Out of memory
error, the heap size needs to be increased. This can be done in the application deployment descriptor (JNLP file) or in the Java Control Panel using Runtime Parameters for JRE in use.
If an application is signed and the user declined a security dialog, this may cause application failure. The decision made by the user is remembered until the JVM is restarted. To see the security dialog again, the user may need to restart the browser.
Note: An applet can be deployed to reduce the risk of being affected by other applets and tailor execution environment for the applet's needs. See Applet Deployment in the JDK documentation. In particular, consider using the separate_jvm parameter
argument.
The following are scenarios that could cause an unresponsive web page.
Frozen applet at applet start or during runtime:
The cause for a frozen applet at applet start or during runtime could be Liveconnect calls.
On startup, an attempt to access the Java applet from JavaScript may block the JavaScript engine until the applet initialization is complete. It is recommended to postpone JavaScript access until the applet is ready and use the enableStatusEvents
parameter to unlock non-blocking access to applet status checks. See Applet Status And Event Handlers for details and examples.
To use Liveconnect in runtime, it is recommended to make JavaScript calls return quickly to avoid blocking the single-threaded JavaScript engine.
Applet or browser hangs:
The best source of information in this case is the stack state for both client and browser JVMs.
Use jstack to collect the JVM stack status for the browser JVM (by running jstack browser-pid
) and client JVM. Note: The jstack
may highlight a deadlock if it happens in context of one of these VMs, but it cannot do this if the deadlock involves both processes. In this case, the thread stacks need to be examined manually. See for more details.

How Powerful are Graph Neural Networks?
21 Oct 2019 Graph neural networksGraph neural networks (GNNs) is a framework that allows to learn representations in a graph. This paper (Xu et al., 2018) discusses previous architectures, analyses their power of representation and presents their own GNN which is maximally powerful under certain constraints.
GNN architecture
In this NN architecture we learn to predict a vector representation for each node in a given graph. Each node \(v\) in this graph \(G=(V,E)\), with a fixed representation of nodes and edges, contains a vector of real numbers \(X_v\) that changes in order to learn one of the following: (1) Node classification, where given a classification \(y_v\) for each node and a function \(f\), we learn \(X_v\) such that \(f(X_v) = y_v\); (2) Graph classification, where given a set of graphs \(G_1,...,G_n\) classified by labels \(y_1,...,y_n\) and an aggregation function \(h\), we learn \(X_v\) for each node such that the aggregation of each graph matches its label i.e. \(h(G_i) = y_i\).
If we only want to learn the representation of the nodes (case 1), we define two operations, aggregate and combine (as in the image below) that tweak the representation of each node with respect to its neightbours. This functions are learnable and are run a certain number of times (K) so no full convergence is required. In the case we want Graph classification (case 2), a readout operation is implemented as well, which maps the set of nodes to the same space as the graph classes. After the final (K) iteration of aggregate & combine operations in the graph, the loss of the nodes/graph is calculated w.r.t. the target classes and the aggregate & combine functions are updated by calculating the derivatives of the loss to the learnable parameters (the matrix W in the example below). Then, iterations are repeated until we get the target representations.
Analysis and limitations
To analyse how powerful GNN architectures are, the authors propose the Weisfeiler-Lehman (WL) test:
Basically, an embedding (i.e. a function that maps the nodes of a graph to a vector space) has to map the nodes of different graphs to different vectors. The difference between this test and normal graph isomorphism is that it does not require isomorphic (i.e. structurally equivalent) graphs to be mapped to the same vector. This has been shown to work well in most cases (except regular graphs).
GNNs are at most as powerful as the WL test (otherwise they would solve graph isomorphism in polynomial time, a complexity problem not solved to the date of this post, although not-confirmed quasipolynomial time algorithms have been shown in the literature). Still, they can be exactly as powerful as the test if the following conditions are met:
GINs
Next, the authors present Graph Isomorphism Networks (GIN) that satisfy the theorem above. Namely, GINs can model any Graph classification (case 2) problem and obtain the representation of each node, such that (by theorem) if two graphs are different, nodes are guaranteed to be assigned different representations. The nodes, edges and node embeddings are modeled as explained before, what they define is a particular aggregate & combine function that satisfies the theorem.
They also suggest a readout function that works well in practice from previous literature:
Finally they compare the power of their architecture to others and test GINs in practice vs. GCN and GraphSAGE.
Conclusion
-
Developed theoretical foundations for reasoning about the expressive power of GNNs.
-
Designed a provably maximally powerful GNN under the neighborhood aggregation framework.
-
Achieved state-of-the-art performance.

THE BACHELOR (1999) * Directed by Gary Sinyor. Written by Steve Cohen. Photography, Simon Archer. Editing, Robert Reitano. Production design, Craig Stearns. Music by David A. Hughes & John Murphy.Produced by Lloyd Segan & Bing Howenstein. Cast: Chris O'Donnell (Jimmy), Renee Zellweger (Anne), Artie Lange (Marco), Edward Asner (Gluckman), Hal Holbrook (O'Dell), James Cromwell (Priest), Mariah Carey (Ilana), Brooke Shields (Buckley), Peter Ustinov (Grandad), et al. A New Line Cinema release. 101 minutes. PG-13
In 1925, Buster Keaton directed and starred in the silent classic "Seven Chances," which was itself based on an eponymous play. It was, and still is, a riot.
"The Bachelor" is a remake-update of Keaton's comedy/farce. The director, is the Brit Gary Sinyor, whose feature debut was the amusing, Jewish-themed comedy "Leon the Pig Farmer" (1992), a work modestly distributed, hence seen in specialized venues such as festivals. Sinyor made two more films which, to my knowledge, have been seen by even smaller audiences. "The Bachelor," if there's any justice, ought to meet with the same non-reception. But one cannot count on that.
When I watched the film with a small audience, a viewer near me kept laughing aloud, and commenting. I was doubly irritated, by my fellow-viewer and by the film. Since I did not want my annoyance to influence my judgment, I moved discreetly to a quiet part of the theater. The move did not improve the movie.
"The Bachelor" opens with much footage of wild mustangs to hammer the point that this is just what bachelor men are. Ugh. Then, Jimmy (a pallid, personality-less O'Donnell) is singled out as another younger man playing the field. He is, however, lucky enough to enter into a three-year relationship with Anne (Zellweger), who is a perfect companion and (supposedly), is not pushing for marriage. However, for reasons unclear, Jimmy feels compelled to pop the question. He does this at a fancy restaurant where, apparently, fellow-bachelors traditionally take their girl-friends to offer them wedding bliss. (Are there such places?)
 Some courtship! Incensed, the girl walks out on him. His later efforts at making up for his idiocy are spurned.
Then grandpa (Ustinov), the very wealthy owner of a pool-table factory, dies, leaving a will on video. Jimmy will inherit one hundred million dollars if he marries on his 30th birthday --which just happens to be a bit over 24 hours away. So Jimmy re-proposes to Anne, who says no. This sends him on a frantic searc for another instant bride. Riding a limousine with his best friend - the fat Marco- and a thin clergyman (James Cromwell), he locates, meets and proposes to (all this with impossible speed) several of his ex girl-friends. They are all shown as caricatures. They all refuse.
As a last resort, Marco places a big newspaper ad which results in an army of willing brides, all in wedding gowns, mobbing and besieging Jimmy.
You can see the happy ending coming ,from a thousand miles away. To wit, Anne's change of heart at the last minute, and the twosome's beating of the clock at the last second.
"The Bachelor" is a one-and-a half joke flick, dull, mechanically repetitious within its agitated search and its regular cuts to Anne and her sister -- the latter used as the female equivalent of "the straight man" in vaudeville routines.
The time element is entirely incredible, far more so than "Around the World in Eighty Days." It is inconceivable that so much happens in so short a time. The characters are dull, except for Brooke Shields as a cold, calculating socialite and gold-digger. Edward Asner and Hal Holbrook are embarrassingly wasted. In his small part, the great, versatile Peter Ustinov is a bad imitation of an eccentric, authoritarian old geezer with a bad imitation of an American accent. James Cromwell, whose corrupt, sinister chief of police was so chill-making in "L.A. Confidential," is the clergyman, He goes, unbelievably, from a silent, dumb-looking character to a suddenly active one.
Worse than anything else is the "piece de resistance" : the anonymous throng of hundreds (thousands?) of eager brides-to-be, all of them grasping harridans, all wearing ugly wedding-dresses, all vulgar and repulsive. Buster Keaton knew something when he kept his camera mostly at a distance which did not personalize those women. And the fact that his film was silent is a blessing.

Charlotte Crosby dishes on how living with Josh Ritchie has changed their relationship
EXCLUSIVE: The former Geordie Shore star recently relocated to Bolton to move in with beau Josh Ritchie - and she tells us it's going amazingly so far
by Vicki Newman, https://www.mirror.co.uk/authors/vicki-newman/Charlotte Crosby says she feels closer than ever to boyfriend Josh Ritchie .
The former Geordie Shore star waved goodbye to the Toon to move in with Josh in Bolton, and things are going better than ever.
The couple's two-year romance has been through some rocky patches, with them arguing over when to have kids and about how often he goes on lads' nights out.
But Charlotte, 29, says moving in together has been bliss.
Charlotte opened up about how her relationship has changed during an exclusive chat with Mirror Online ahead of the new series of her MTV show Just Tattoo Of Us.
She said: "I've not spent much time [at the house], I was there for a week so I could get all the deliveries and furniture in but then after that I was back in Australia, came back yesterday and I'm away again so had one day there.
"I'm hardly at the house but I do see Josh all the time, we've just spent three weeks in Australia together, but I've never been in one place more than one week at a time, that's why I decided to rent my house out because it was a complete and utter waste of money, it was just sitting there empty."
She added: "We have learnt a lot more [since moving in together] and it's been really, really good. We're getting on so well, I think it's brought us closer together.
"We've had no arguments about cleaning and stuff, he's so tidy, always doing the washing, it's really been perfect."
Just Tattoo Of Us is returning for a fifth season.
And it's set to be wilder than ever thanks to a brand new twist.
Charlotte explained: "I'm very proud that it's got that far, a lot of shows will only have one series then not get recomissioned. I couldn't be prouder, I love its craziness and its completely unfiltered nature and this series is just taking it to a whole new level.
"Now we've got this stick or twist which is where people have got the option to stick with the tattoo their friend's given them or twist and get a completely random tattoo designed by one of the artists, and that element to it is a complete gamble and this tattoo could be worse or better.
"People get so p****d off when they choose to twist. It just opens up a brand new can of worms, there's all these new elements you could be angry about because your friend could have got you a nice one and you end up with a horrible one and they'll be p****d off because you didn't trust them.
"It makes the show even crazier and I didn't think it could get any crazier."
Again this series, Charlotte will be joined by guest hosts, including her boyfriend, Geordie Shore co-star Chloe Ferry and Love Island's Olivia Attwood .
But Charlotte admits she's ready for a regular co-host again.
She said: "I'm ready to have a regular co-host again, it's all over the place when there's guests. For me, it's quite hard because I'm getting a different person every couple of days and most of the time they don't know what they're doing and the producers rely on me to bring it back.
"If we get a guest host who isn't very good or doesn't know what they're doing I have to do their job for them too so I'm doing a lot more work, so I think it's time we had a regular."
Charlotte also confirmed the fourth series of The Charlotte Show will begin filming next year.
*Charlotte Crosby is back with Just Tattoo Of Us series five, which premieres Monday, November 18 at 10pm on MTV

Guy mashes Mario Party 4 real good
Just watching this Domination record makes my thumb ache
by Jordan DevoreWin or lose, I've literally never ended a round of Mario Party 4 feeling good about myself, my fellow players, or this wretched game – and yet I always come crawling back after enough time has passed. That's how it's always been, and that's how it'll always be. Why Mario Party 4? It's just what I have!
A breakout Mario Party clip from Twitch streamer ludwig circulated over the weekend, and for good reason: it's as impressive as it is painful. Watch him mash like a madman in the Domination minigame.
Not only did Ludwig wail on his controller fast enough to earn 201 points in this endurance-testing minigame – a remarkable feat in its own right – he did it while playing as Luigi. Way to represent.
 I feel like Ludwig just got revenge on Mario Party 4 on our behalf.
I also now feel like my thumb has a phantom secondhand soreness.

Dr. Ekeblom decided that the best way to help people and clients was to set up a consulting firm. It acts as a vehicle to offer clients' solutions to problems that orginate from the intersection of domains such as software, finance and statistics.
The book accounts for the financing provided by commercial banks to the Swedish real estate market in the form of covered bonds, with the central bank as an implied guarantor for the banks' liabilities. The purpose of the book was to fill an apparent void in the teachings of mainstream macroeconomics. Only available in Swedish.
The Ph.D. culminated in a dissertation with the title Empirical Essays in Expectations. Chapter 3 establishes that the communication channel of the Swedish Central Bank (Riksbanken) exhibits small and transient effects as a means of managing Inflation Expectations, exploiting a natural experiment regression set up.
Working as an M&A analyst for a global finance/tech company during the height of the financial crisis was highly formative experience. The connectedness of individuals through information, and companies through leverage, had a striking effect on the macroeconomic environment.
Daniel's education culminated in a master thesis with the title What is the Probability of a Recession in the United States? It came in handy during the financial crisis of 2008.
Daniel served as a Liaison Officer (Sgt), with technical training of radio, network and computer hardware, as well as leadership training.


IRIS Testing Evaluations
Iris currently offers one service to our customers: fiber test results review and certification. Iris reviews to data and photos taken of the fiber/radio installation to determine if any installations errors exist. This service can performed “real-time” while testing is taking place, or after the testing has been completed. We certify that all the radios are corrected configured and that the RET (remote antenna downtilting capabilities) system is functioning correctly. For these services we currently charge a $1,000.00 fee.

The Problem. Government agencies, advocacy groups, and global firms hope to influence particular outcomes at the intersection of the private, public, and social sectors. But it's not easy figuring out whom to influence. While these organizations rely on a network of experts, they have no systematic, scaleable method for aggregating the information they receive. Many of their decisions are based on intuition and wisdom.
The Solution. Through the power of machine learning, we hope to dramatically enhance the power of expert opinions. We believe experts are best at providing facts. Who holds influence? Who is focused on the issue? Who is willing to compromise? But we also believe computers can spot trends that humans miss. If we want to get the most complete picture of any geopolitical landscape in a rigorous, reproducible method, we must combine the two.
Rohan, Daniel, and Milton became friends in the fall of 2010 as high school freshmen. When Daniel and Milton heard Rohan tell them about a problem he encountered, their passions for politics, strategy, and tech collided. At their core, they're just curious to see how computer science and statistics can help people make decisions.
Rohan studies statistics at Harvard. He grew up in Chicago and loves following politics.
Milton is studying Applied Math at Harvard. A proud New Yorker, he spends free time solving puzzles.
Daniel studies computer science at MIT. As a Florida native, Daniel loves any time on the beach.


Lots of fruit and vegetables, little meat and hardly any sweets or alcohol: In theory, we know how to eat healthily. But we often don't do this in everyday life. Who can snip fresh salads or prepare delicious stir-fried vegetables during the day when they only find chips stands on the way or simply don't have time to eat?
Shades of light green, beige and red create a really fresh and invigorating aura around them, leaving a stunning mint freshness inside. This is an excellent design solution for an institution that has taken a course towards a healthy lifestyle, since such a fresh palette will only emphasize the taste and benefits of those dishes that visitors will receive. The harmony of these colors will not only be beautiful, but also embody the unity of ease and benefit. Photo by Alexandra Golovac on…
Sip your way to a healthier breakfast by blending your produce each morning. These smoothie recipes will get your day started off right by packing in nutrient-rich fruit and vegetables, plus protein-filled yogurt and milk for an energy boost that will keep you going until lunch. And unlike what you might get from store-bought options, they prioritize actual produce instead of the juices, sorbets and sweeteners that can add tons of sugar to your cup. Our Good Housekeeping Institute Kitchen Appliances Lab also tested the best blenders for whipping up the smoothest, creamiest drinks. The Vitamix E310 Explorian nabbed our top spot, but check out Black + Decker XL Blast Drink Machine as a budget buy or the NutriBullet Balance for single-serve options. To make sure nothing goes to waste, store your ingredients in freezer-safe bags or containers for up to nine months. Smoothies can separate within a few hours in the fridge, so mix everything up when you're ready t0 drink. If you need to prep drinks ahead, adding a teaspoon of lemon juice before refrigerating can prevent oxidation. Ready to get started?

Eating right has never been more important than now. We are facing a pandemic that affects different people with various grades of severity — that ranges from asymptomatic to outright fatality. The buzzword is immunity. And it all comes down to the individual’s health and wellness that decides the severity of COVID-19 infection or the prevention of the same. With the inundation of conflicting information on our timelines — here we have attempted to sort, verify and plan your grocery list with a focus on foods, diets and ingredients that can help to boost your immunity and equip your body for COVID-19 prevention, management and recovery. Nutritionists, chefs and other experts weigh in with valuable suggestions, recipes and diet tips.

1. Introduction
Load is not a single moment in time — it’s an experience that no one metric can fully capture. There are multiple moments during the load experience that can affect whether a user perceives it as "fast" or "slow".First Paint (FP) is the first of these key moments, followed by First Contentful Paint (FCP). These metrics mark the points, immediately after navigation, when the browser renders pixels to the screen. This is important to the user because it answers the question: is it happening?
The primary difference between the two metrics is FP marks the point when the browser renders anything that is visually different from what was on the screen prior to navigation. By contrast, FCP is the point when the browser renders the first bit of content from the DOM, which may be text, an image, SVG, or even a canvas element.
1.1. Usage example
var observer= new PerformanceObserver( function ( list) { var perfEntries= list. getEntries(); for ( var i= 0 ; i< perfEntries. length; i++ ) { // Process entries // report back for analytics and monitoring // ... } }); // register observer for paint timing notifications observer. observe({ entryTypes: [ "paint" ]});
2. Terminology
Paint: the browser has performed a "paint" (or "render") when it has converted the render tree to pixels on the screen. This is formally defined as the when update the rendering happens in event loop processing.
NOTE: The rendering pipeline is very complex, and the timestamp should be the latest timestamp the browser is able to note in this pipeline (best effort). Typically the time at which the frame is submitted to the OS for display is recommended for this API.
First Paint entry contains a DOMHighResTimeStamp
reporting the time when the browser first rendered after navigation. This excludes the default background paint, but includes non-default background paint and the enclosing box of an iframe. This is the first key moment developers care about in page load – when the browser has started to render the page.
First Contentful Paint entry contains a DOMHighResTimeStamp
reporting the time when the browser first rendered any text, image (including background images), non-white canvas or SVG. This excludes any content of iframes, but includes text with pending webfonts. This is the first time users could start consuming page content.
3. The PerformancePaintTiming
interface
[Exposed =Window ]interface :
PerformancePaintTiming PerformanceEntry {};
PerformancePaintTiming
extends the following attributes of PerformanceEntry
interface:
-
The
name
attribute must return aDOMString
for minimal frame attribution. Possible values of name are:-
: for First Paint"first-paint" -
: for First Contentful Paint"first-contentful-paint"
-
-
The
entryType
attribute must return
."paint" -
The
startTime
attribute must return aDOMHighResTimeStamp
of when the paint occured. -
The
duration
attribute must return 0.
NOTE: A user agent implementing PerformancePaintTiming
would need to include
and
in supportedEntryTypes
for Window
contexts.
This allows developers to detect support for paint timing.
4. Processing model
4.1. Reporting paint timing
4.1.1. Mark paint timing
-
Let paintTimestamp be the input timestamp.
-
If this instance of update the rendering is the first paint, then record the timestamp as paintTimestamp and invoke the § 4.1.2 Report paint timing algorithm with two arguments:
and paintTimestamp."first-paint" NOTE: First paint excludes the default background paint, but includes non-default background paint.
-
Otherwise, if this instance of update the rendering is the first contentful paint, then record the timestamp as paintTimestamp and invoke the § 4.1.2 Report paint timing algorithm with two arguments:
and paintTimestamp."first-contentful-paint" NOTE: This paint must include text, image (including background images), non-white canvas or SVG.
-
Otherwise, do nothing and return.
NOTE: A parent frame should not be aware of the paint events from its child iframes, and vice versa. This means that a frame that contains just iframes will have first paint (due to the enclosing boxes of the iframes) but no first contentful paint.
4.1.2. Report paint timing
-
Create a new
PerformancePaintTiming
object newEntry and set its attributes as follows: -
Add the PerformanceEntry newEntry object.

Tottenham fans will quickly forget Jose Mourinho's previous misdemeanours if he wins trophies
Jose Mourinho's arrival hasn't gone down well with Tottenham fans but the new manager has been appointed to win trophies
by Andy Dunn, https://www.mirror.co.uk/authors/andy-dunn/Whatever you think of Jose Mourinho, he can charm the cockerels from wherever.
When he is officially presented to the world as the new Spurs manager, he will be speaking fluent Chas ’n Dave.
If Danny Blanchflower, Bill Nicholson, Dave Mackay, Glenn Hoddle and Harry Kane don’t get a mention, it will be a shock.

On Wednesday morning, polls on social media suggested at least two-thirds of the Spurs fanbase prefer Mauricio Pochettino to Mourinho.
That will not go unnoticed by Mourinho. He will be gushing in his praise of Poch and suitably humbled by the £15million-a-year chance to manage such a great club.
People get Mourinho’s ego wrong. It is not the size you think. It is far bigger.
His managerial office is always a shrine to himself. His son is named Jose.
But as much as Tottenham supporters, quite understandably, adore Pochettino, as much as they might loathe the way Mourinho has behaved in previous incarnations, Jose will probably have them at "hello".
And that is why Daniel Levy, for all the initial indignation, is not risking the club’s relationship with its supporters.
He is employing someone who will not talk in vague, holistic terms about the direction of the club.
He will, pure and simple, talk about winning trophies - something Spurs have not been doing for some time.
The loveliness of Pochettino will long be forgotten if, for example, the FA Cup is raised in Spurs colours next May.
Is Mourinho the right appointment? Probably not.
Will, after the initial shock of a favourite son being jettisoned, the Spurs faithful enjoy the trophy-hunting ride? Yes.
Will they enjoy - despite being 14th in the Premier League table - being the centre of attention? Yes.
And that is why Levy will not have had a moment’s worry about the reaction to this decision.

Rails Callback Best Prectice Part 1
- Guideline 1: Omit When Possible
- Guideline 3: Prefer after_commit to after_save
- Guideline 5: Don’t use for data validation
Here are our guidelines:
Omit when possible
Asynchronous by default
Prefer after_commit to after_save
Avoid conditional execution
Don’t use for data validation
Guideline 1: Omit When Possible
Callbacks ensure that anyone updating or saving a record won’t forget to perform an operation that should be performed on #save.
Most parts of our applications directly modify our ActiveRecord::Base subclasses instead of using a service object to perform an operation. More and more, we are trying to use service objects to encapsulate groups of operations rather than callbacks.
Let’s take a look at a code example for a hypothetical company onboarding flow:
# Bad
class Company < ActiveRecord::Base
after_commit :send_emails_after_onboarding
private
def send_emails_after_onboarding
if just_finished_onboarding?
EmailSender.send_emails_for_company!(self)
end
end
end
# Good
class Company < ActiveRecord::Base
end
class CompanyOnboarder
def onboard!(company_params)
company = Company.new(company_params)
company.save!
EmailSender.send_emails_for_company!(company)
end
end
By locating our logic in a service object and not a callback, we are not adding logic that will need to run after every #save. Because we have a service class to handle signing up a company, we also reduce the coupling between Company and EmailSender.
Guideline #2: Asynchronous by default Whenever we add a callback, that is code that will execute before we can respond to a request. If a class defines 20 callbacks, that’s 20 blocks of code that must execute before we can respond to the user. Generally, this will make requests take longer. Requests that take longer result in a sluggish experience on the front-end.
Therefore if you must write a callback, make sure it gets out of the critical path of the request by making the bulk of itself asynchronous. (Note: This only applies to logic that does not need to exist within the same transaction.) For us at Gusto, that means enqueuing a Sidekiq job.
Let’rubys look at an example:
# Bad
class Company < ActiveRecord::Base
after_commit :create_welcome_notification, on: :create
private
def create_welcome_notification
# We're incurring an extra database request here, which
# is something we want to avoid during
# critical operations like signing up a
# new customer
notifications.create({ title: 'Welcome to Gusto!' })
end
end
# Good
class Company < ActiveRecord::Base
after_commit :create_welcome_notification, on: :create
private
def create_welcome_notification
WelcomeNotificationCreator.perform_async(id)
end
end
class WelcomeNotificationCreator
include Sidekiq::Worker
def perform(company_id)
@company = Company.find(company_id)
@company.notifications.create({ title: 'Welcome to Gusto!' })
end
end
Now, you might say, “But the ‘Good’ example is way more code than the ‘Bad’ one! It now takes 2 files!” You would be correct. Writing callbacks in a safe manner by moving the bulk of the logic into a worker will result in more code. The resulting code, however, will reduce coupling on our models and make each component more testable.
Spearubyking of tests, here’s a good way to test callbacks like this using RSpec:
# spec/models/company_spec.rb
require 'rails_helper'
RSpec.describe Company, type: :model do
describe '#save' do
subject { company.save }
let(:company) { build(:company) }
it 'schedules a WelcomeNotificationCreator job' do
expect {
subject
}.to change{ WelcomeNotificationCreator.jobs.size }.by(1)
last_job = WelcomeNotificationCreator.jobs.last
expect(last_job['args']).to eq([subject.id])
end
end
end
# spec/workers/welcome_notification_creator_spec.rb
require 'rails_helper'
RSpec.describe WelcomeNotificationCreator do
subject { described_class.new.perform(company.id)}
let(:company) { create(:company) }
it 'creates a notification' do
expect {
subject
}.to change(Notification, :count).by(1)
expect(Notification.last.title).to eq('Welcome to Gusto!')
end
end
Guideline 3: Prefer after_commit to after_save
When writing a callback where you want to execute code after a save, create, or update, default to using an after_commit block.
after_commit is the only callback that is triggered once the database transaction is committed. Putting it simply, it’s the only callback whose state will match “the outside world,” specifically the same state that worker process will see.
Without an after_commit callback, you may see strange errors in Sidekiq to the tune of Cannot find Company with ID=12345. These errors will be frustrating to track down because they will only raise once before passing without a problem.
What’s happening with this error is that Sidekiq is picking up the job before the database has committed the new record to it. To the outside world, it looks like your new record does not yet exist. It can be an incredibly frustrating race condition to debug.
The safe default is to use after_commit.
Let’rubys take a look at 2 different code examples:
# Bad
class Company < ActiveRecord::Base
after_create :create_welcome_notification
private
def create_welcome_notification
# The database transaction has not been committed at this point,
# so there's a chance that the Sidekiq worker will pick up the job
# before our `Company` has been persisted to the database.
WelcomeNotificationCreator.perform_async(id)
end
end
# Good
class Company < ActiveRecord::Base
after_commit :create_welcome_notification, on: :create
private
def create_welcome_notification
WelcomeNotificationCreator.perform_async(id)
end
end
Please note: The *_changed?
helpers are not available within after_commit. If you need to conditionally execute a callback, please be aware of this and use the alternative method if looking at the previous_changes hash. Or…
Guideline #4: Avoid conditional execution As a general rule, do not write callbacks that are conditional.
Instead, try to make callbacks that are idempotent and can be safely run multiple times. This is especially important when you begin moving your callback logic to Sidekiq jobs. (See the best practices on Sidekiq to see why Sidekiq jobs must be idempotent.)
Note that this will enqueue more jobs onto Sidekiq, but many of these jobs should be no-ops.
If you must conditionally execute a job, please define that logic within the method body and not in the callback signature. The reason for this is to make sure that the conditions only live in a single place. It’s much easier for the conditional to grow in the method body instead of on the line that defines the conditional.
Let’rubys take a look at a few examples:
# Bad
class Company < ActiveRecord::Base
after_commit :create_welcome_notification, if: -> { should_welcome? && admirable_company? }
private
def create_welcome_notification
WelcomeNotificationCreator.perform_async(id)
end
end
# Good
class Company < ActiveRecord::Base
after_commit :create_welcome_notification
private
def create_welcome_notification
if should_welcome? && admirable_company?
WelcomeNotificationCreator.perform_async(id)
end
end
end
# Best
class Company < ActiveRecord::Base
after_commit :create_welcome_notification
private
def create_welcome_notification
WelcomeNotificationCreator.perform_async(id)
end
end
class WelcomeNotificationCreator
include Sidekiq::Worker
def perform(company_id)
@company = Company.find(company_id)
return unless @company.should_welcome? && @company.admirable_company?
# We passed our check, do the work.
end
end
Please keep in mind that things like on: :create are their own flavor of conditional execution. Generally, try to push that logic into the worker.
Guideline 5: Don’t use for data validation
It is possible to use callbacks for data validation, but that should be avoided. ActiveRecord makes certain assumptions on how and when validations will be run, and putting these in callbacks breaks some of those assumptions.
Instead, use the ActiveRecord Validations API.
Conclusion With great power comes great responsibility, and Rails callbacks are no exception. They are expressive tools but also come with drawbacks.
We are generally moving away from using callbacks and toward using rich service objects in our applications, but we still have many callbacks that exist. We still have a lot left to do, but we’ve found that the code that follows these guidelines requires less maintenance.
