How to catch Eevee
Where to find Eevee
Eevee can be found in the grass on Route 4 at any time during the day or night. You'll arrive at Route 4 after taking the train from Wedgehurst.
Eevee is very elusive, so it's going to take a while for it to appear. Keep wandering around in the tall yellow grass and keep an eye out for those adorable tell-tale ears sticking out.

How to catch Eevee
- Enter into a Pokemon battle with Eevee.
- Weaken it with one of your Pokemon until its HP is in the 'red' zone.
- Throw a Pokéball and hope for the best!

How to evolve Eevee
Evolving Eevee in Pokemon Sword and Shield is relatively easy. Simply level up your Eevee a little bit so it is at least level 15 and then use one of the following stones on it:
- Flareon = Use a fire stone
- Jolteon = Use a thunder stone
- Vaporeon = Use a water stone
- Leafeon = Use a leaf stone
- Glaceon = Use an ice stone
For Espeon and Umbreon the process is slightly different as you must raise your friendship level with your Eevee in your camp by playing with it, feeding it and using it to practice fighting in your camp. Once your friendship with that Eevee has been maxed out, the next time it evolves it will transform into either Espeon if it levels up during the day or Umbreon if it levels up during the night.

THEORY OF FLIGHT, THE
Reviewed by Harvey Karten, Ph.D. Fine Line Pictures/BBC Films Director: Paul Greengrass Writer: Richard Hawkins Cast: Helena Bonham Carter, Kenneth Branagh, Gemma Jones, Holly Aird
When you pass somebody who seems quite a bit different from the usual passersby--perhaps a homeless man with unkempt hair and dirty clothes, maybe a person who is just 3 feet tall, could be someone who is not only in a wheelchair but breathing with a the aid of a tube--you are likely to believe that this individual is wholly distinct from all others on the street. You may be correct. But you may also be overlooking two other factors. 1) The person with the strange appearance may have sharp mental functions totally unaltered by his or her physical condition; and 2) The accompanying person who looks wholly ordinary may in fact be the one with unorthodox mental functioning.
In "The Theory of Flight," Paul Greengrass makes use of Richard Hawkins's wholly original script to unfold a comedy of offbeat proportions between two such individuals. Jane (Helena Bonham Carter) is a woman of just twenty-six years who'd likely get a wide berth from others. She is wheelchair bound, suffering from terminal Lou Gehrig's Disease, a severe neurological condition which does not affect her intellect or her ability to feel but restricts her physical movement and slurs her speech almost beyond comprehension. Richard (Kenneth Branagh), looks reasonably average but has a Peter Pan complex, a refusal to grow up, which leads him at one point to go literally over the edge. One day, after suffering a mini nervous breakdown, he perches with a pair of wings on the edge of a London building and takes flight--right into a net provided by the police. Winding up in court, he is sentenced to 120 hours of community service and assigned to a rehab center to be Jane's companion.
If you can accept the premise that a court would commission a handsome but troubled young man to escort a virtually paralyzed young woman about, you can embrace the oddities in the rest of the film. As the two get to know each other, the usually untrusting Jane gradually warming up to her escort's infantile dreams of taking flight, Jane asks a favor which serves as the story's bombshell. She is a virgin, having suffered symptoms of deterioration at the age of eighteen, and is obsessed with erotic fantasies. Jane spends most of her time glued to a computer, has been exposed to porno films, sees advertising on the tube that plays up sexual fantasies to sell products, and observes the influence that sex plays in the stories she watches as well. Carefree that Richard may be, he cannot bring himself to satisfy what is far more than a passing whim of this woman, a person who is treated like a child by so many others and who therefore can relate to Richard's own, self-created immaturity.
"The Theory of Flight" has a modicum of comical and sentimental scenes alike. One involving Richard's hiring of a strikingly handsome gigolo for his unfortunate friend is a gem with both farcical and tragic import, while the schemes of Richard's ex-girl friend Julie (Holly Aird) play up the restraining, even joyless nature of the down-to-earth life.
Ultimately the film does not soar. Director Paul Greenglass does what he can to liberate the two from all that is holding back their enjoyment of human existence, but though he films much of the comedy on the rolling hills of Bristol, "The Theory of Flight" has the imprint of staged play: two frustrated oddballs turning their backs on society to work out their defeats and disappointments. Helena Bonham Carter, who has studied the movements and attitudes of people with severe neurological challenges, is convincing, making the audience listen closely to understand her speech. Kenneth Branagh still belongs, in my opinion, to heroic roles, and should avoid cloning Woody Allen as he did to some extent in this film and in "Celebrity" before it. His stuttering is irritating enough: his frequent use of the adolescent expression "you know" is dispiriting, just as Woody Allen's was in the latter's "Full Tilt Boogie." The performers and director do realize the writer's contention that you may have a disease, but the disease needn't have you, but do so in such a feathery manner that the movie lacks a sufficient sense of comedy, catastrophe, or convincing eccentricity.

The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five dollar bet over highballs, and it happened this way:

Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As well as any human beings could, they knew what lay behind the cold, clicking, flashing face -- miles and miles of face -- of that giant computer. They had at least a vague notion of the general plan of relays and circuits that had long since grown past the point where any single human could possibly have a firm grasp of the whole.

Multivac was self-adjusting and self-correcting. It had to be, for nothing human could adjust and correct it quickly enough or even adequately enough -- so Adell and Lupov attended the monstrous giant only lightly and superficially, yet as well as any men could. They fed it data, adjusted questions to its needs and translated the answers that were issued. Certainly they, and all others like them, were fully entitled to share In the glory that was Multivac's.

For decades, Multivac had helped design the ships and plot the trajectories that enabled man to reach the Moon, Mars, and Venus, but past that, Earth's poor resources could not support the ships. Too much energy was needed for the long trips. Earth exploited its coal and uranium with increasing efficiency, but there was only so much of both.

But slowly Multivac learned enough to answer deeper questions more fundamentally, and on May 14, 2061, what had been theory, became fact.

The energy of the sun was stored, converted, and utilized directly on a planet-wide scale. All Earth turned off its burning coal, its fissioning uranium, and flipped the switch that connected all of it to a small station, one mile in diameter, circling the Earth at half the distance of the Moon. All Earth ran by invisible beams of sunpower.

The Spray Slick Swagger is a very simple rest api in Spray showing one way of using spray with slick 3 library for database access, and spray-swagger for documentation the routes in spray.
It supports the following features:
Utils: Typesafe config for property management and Typesafe Scala Logging (LazyLogging)
The project was thought to be used as a seed for creating spray projects with this features, so the implementation is minimal. The model is very simple, is a supplier with a name and description.
The rest api has a get and a post (json), a get for get all the suppliers, and a post to add suppliers. You should view this info in swagger with more detail.
For running the project go to section run, and run it.
For running the project in sbt:
$ sbt
> run
Models as case classes and slick 3 schemas
case class Supplier(id: Option[Int],name: String,desc: String)
class Suppliers(tag: Tag) extends Table[Supplier](tag, "SUPPLIERS") {
def id = column[Int]("id", O.PrimaryKey, O.AutoInc)
def name = column[String]("userID")
def desc = column[String]("last_name")
def * = (id.?, name, desc) <> (Supplier.tupled, Supplier.unapply)
}
(Removed in v0.0.2) Data Access layer as actors instead of the usual dal classes. Class SuppliersDAA.scala (DAA stands for Data Access Actor) represents the actor for suppliers data operation. The operations are represented in actor messages. For instance, for get a supplier by id, the actor has this case in the receive method:
case GetSupplierById(id) ⇒ sender ! db.run(suppliers.filter(_.id === id).result)
(v0.0.2) Data Access layer as the usual dal classes. Class SuppliersDal.scala
The model definition is database independent. The database type is declared in application.conf, for each database. For instance, we use an h2 database in this example with the follow configuration:
h2db {
driver = "slick.driver.H2Driver$"
db {
url = "jdbc:h2:mem:test1"
driver = org.h2.Driver
keepAliveConnection = true
numThreads = 10
}
}
The spray and swagger are integrated in the routes files. To integrate swagger with play, each route has to be a scala def, example:
@ApiOperation(httpMethod = "GET", response = classOf[Supplier], value = "Returns a supplier based on ID")
@ApiImplicitParams(Array(
new ApiImplicitParam(name = "supplierId", required = true, dataType = "integer", paramType = "path", value = "ID of supplier that needs to be fetched")
))
@ApiResponses(Array(
new ApiResponse(code = 200, message = "Ok")))
def SupplierGetRoute = path("supplier" / IntNumber) { (supId) =>
get {
respondWithMediaType(`application/json`) {
onComplete((modules.suppliersDAA ? GetSupplierById(supId)).mapTo[Future[Seq[Supplier]]]) {
case Success(photos) => complete(photos)
case Failure(ex) => complete(InternalServerError, s"An error occurred: ${ex.getMessage}")
}
}
}
}
For json marshalling the spray json is used with the case classes:
object JsonProtocol extends DefaultJsonProtocol {
implicit val supplierFormat = jsonFormat3(Supplier)
implicit val simpleSupplierFormat = jsonFormat2(SimpleSupplier)
}
This seed uses cake pattern to add the possibility to use alternative implementations of some modules, for instance, in tests, the seed uses an alternative implementation for persistence.
The seed are organized in modules: ActorModule, ConfigurationModule and PersistenceModule. When we are implementing a class/actor that uses some of this dependencies, we just mix them with the modules, or put a parameter that receives the injected modules, for instance:
class RoutesActor(modules: Configuration with PersistenceModule)

Pat's Salmon Cookies are the world's first cookies that are both shaped like AND flavored with salmon. The salmon is finely ground so you get all the protein and none of the fishy flavor. They're perfect with a cup of coffee on a cold rainy day and the fun fishy shape will help put a smile on your face. Once you try one, you'll be a fan for life!
Our Story
Pat's Salmon Cookies was founded in 2016 and was borne out of Pat's desire for a delicious coffee-time treat that provided a healthy dose of protein. As he was visiting the Ballard Locks with his family (pictured above) and watching salmon jump up the fish ladder, he got a great idea: salmon cookies! At first he was intrigued by the cute shape, but it soon dawned on him that if he ground the salmon up finely enough, he could add it to the cookies to get a great boost of protein and omega 3 fatty acids without any of the fishy flavor. And thus, Pat's Salmon Cookies were born!
Coming Soon
Online store featuring t-shirts, cookie cutters, art, and more!

4. How can the GUI designer define the HTML if Click Controls generates everything?
-
In Click there is nothing preventing you from laying out HTML forms by hand.
It just provides the option of doing it automatically for you.
There are a number of approaches you can use for generating for HTML,
each with pros & cons:
-
Use Click forms and controls to do all the HTML rendering for you.
This a 80/20 approach where you can quickly get stuff developed, but it may
not meet all your UI style requirements.
Please note the Forms control provides many
auto layout
options, see the click-examples 'Form Properties'
for a demonstration.
The Form control also renders the class attributes 'form', 'fields', 'errors' and 'buttons'
in the form's HTML elements enabling fine grained CSS control.
As an example you could configure a form to display the labels on top, and want to
increase the vertical spacing between fields. To do this simply define the CSS
style in front of your form:
<style type="text/css">
td.fields { padding-top: 0.75em; }
</style>
$form
Fields are also rendered with an 'id' attribute enabling manipulation of individual fields.
-
Subclass Click Form/Controls to customise HTML rendering.
This is a good approach for ensuring a common LAF across your web application,
but you will have to get your hands dirty and write some code.
-
Use Panel class to create reusable HTML blocks.
The
Panel
control support custom Velocity templates, which is an ideal way
to create reusable HTML sections which you can include in many pages.
Panels also support nested controls, enabling your sections to support
control based behaviour.
-
Use Velocity macros for a generic HTML layout.
This is easy to do and gives you good reuse across your web application.
Please see the Form
velocity macros
example, and also see the click-examples 'Velocity Macro'
demonstration.
-
Layout your HTML forms by hand.
This gives you the ultimate control in presentation, but provides no reuse
across your web application.
Please see the Form
manual layout
example.
-
5. How can I customize a control's look and feel (Stylesheet, JavaScript and other resources)?
-
See the section auto deployed files
for details on how to customize and override a control's resources.
-
6. How can I have many Pages using the same HTML template?
-
To do this use the Page templating technique detailed in the
Page Templating topic.
Page templating is highly recommended for your web applications, as it provides
numerous benefits including:
- greatly reduces the amount of HTML you need to maintain
- ensures you have a common look and feel across you application
- makes your application more robust, as there is less code to test
For a live demonstration of page templating deploy and run the
click-examples application.
-
7. Why do control listeners methods have to return a boolean value?
-
Control listener methods have to return a boolean value to state whether the
Pages controls and methods should continue to be processed. To continue
processing listener methods should return true, to abort they should return false.
The reason you may want to abort further processing is so you can navigate
directly to another page, rather than continuing to execute other control or
page methods which may be time consuming. You can use this feature like a break
or goto statement. For example:
public boolean onLogoutClick() {
setRedirect(Logout.class);
return false;
}
Please see the Page Navigation topic
for more details.
-
8. Can you exclude some fields from a Form?
-
To exclude some fields from being displayed in a shared Form class use the
Form.removeFields()
method.
You can even do this in your page template. Just make sure you call you call
it before $form renders itself. For example:
$form.removeFields(["field11", "field15", "field22"])
$form
-
9. How do you internationalize Pages and Controls?
-
Click provides good support for application localization and
internationalization (I18N) requirements.
Page Messages
The Page class supports page specific string localisation bundles using the
method
getMessage(String).
For example a Login class with three locale string property files on the classpath:
/com/mycorp/pages/Login.properties
/com/mycorp/pages/Login_en.properties
/com/mycorp/pages/Login_fr.properties
In your Login Page class you can use the getMessage() method
to lookup request localized message strings.
public void onInit() {
addModel("title", getMessage("title"));
}
In your HTML page template you can also access the localize message using
the MessagesMap
object which is added to the template using the name "messages". For example:
<h2>$messages.title</h2>
You can also define Field and AbstractLink label and title values in your pages
properties file using control name lookup convention. For details please see
the Javadoc:
Control Messages
The Control classes share a common messages properties file:
/click-control.properties
The AbstractControl class provides a number of
getMessage(String)
methods which support localized strings and message formatting.
Please also see the Control topic Message Properties.
-
10. How do you encode Pages in the UTF-8 character set?
-
To encode pages in the UTF-8 character set you need to create a
WEB-INF/velocity.properties file with the properties:
input.encoding=UTF-8
This will configure the Velocity runtime to use UTF-8.
You will also need to set the page headers content type to UTF-8. You can do this globally for all
your applications pages using the headers element in your
WEB-INF/click.xml file:
<click>
..
<headers>
<header name="Content-Type" value="text/html;charset=UTF-8"/>
</headers>
..
</click>
This will set the pages HttpServletResponse "Content-Type" header to be
"text/html;charset=UTF-8". Alternatively you can override the Page
getContentType() method
to this content type.
-
11. How do you specify the character set which is used in your application?
-
You can specify your application character set in WEB-INF/click.xml:
<click charset="UTF-8">
..
</click>
This character set is used for Velocity input encoding, and response Content-Type.
So if you specify the character set in WEB-INF/click.xml,
you don't have to create WEB-INF/velocity.properties.
If you want to use the other character set in your Velocity templates,
you can override input encoding by WEB-INF/velocity.properties.
See the previous topic.
-
12. How can you prevent multiple form posts?
-
You can prevent multiple form posts by using the Post Redirect pattern. With
this pattern once the user has posted a form you redirect to another page.
If the user then presses the refresh button, they will be making a GET request
on the current page.
public class Purchase extends Page {
..
public boolean onPurchase() {
if (form.isValid()) {
Order order = new Order();
form.copyTo(order);
getOrderService().save(order);
// Perform a redirect after post to protect against users pressing
// the refresh or back button
setRedirect(Purchase.class);
return false;
}
return true;
}
}
Please see the Redirect After Post
article for more information on this topic.
Another common way duplicate posts occur is if the user accidentally
click the Form's submit button twice, in quick succession. Redirecting to another
won't protect against the second accidental submit.
Click provides a clean way to prevent users from resubmitting the same Form
through the Form's
onSubmitCheck()
method:
public class Purchase extends Page {
..
public boolean onSecurityCheck() {
// Placing the onSubmitCheck in the onSecurityCheck event, prevents the
// page from being processed if a Form is resubmitted a second time
return form.onSubmitCheck(this, "/invalid-submit.html");
}
}
Please see the Click Examples 'Page Flow' for a demonstration of the
Post-Redirect and submit check patterns.
-
13. How can I use *.html Click pages?
-
Click does not automatically map *.html files as Click pages. These files
are not processed by the ClickServlet and are intended for use as static content.
However see the FAQ on alternative extensions.
-
14. Can Click be mapped to an extension other than *.htm?
-
By default Click supports *.htm and *.jsp extensions.
However you can map templates with different extensions, for example *.xml, by
subclassing XmlConfigService and specify extra mappings by overriding
isTemplate(String path). You can read more details
here.
You can also map URLs to different extensions using
Url Rewrite Filter. It is even
possible to rewrite to REST like URLs:
- rewrite URL from http://www.mycorp.com/book.htm?id=324 to http://www.mycorp.com/book/324 (which will retrieve the book where id=324)
- rewrite URL from http://www.mycorp.com/books.htm to http://www.mycorp.com/books (which will retrieve the list of books)
-
15. What JARs should I use with Click and Cayenne?
-
To get Click and Cayenne to work happily with each other you will need to
include the following JAR files in your WEB-INF/lib directory:
- ashwood-2.0.jar
- cayenne-server-3x.jar
- click-2x.jar
- click-extras-2x.jar
- commons-collections-3.1.jar
- commons-logging-1.1.jar
-
16. How can you integrate Click into Spring?
-
To integrate Spring with Click configure the
SpringClickServlet
instead of the normal ClickServlet. The SpringClickServlet is contained in the
Extras library and provides excellent integration options.
The Spring MVC Framework however, is not compatible with Click. The Spring framework
uses a low level command pattern design like Struts and WebWork.
Spring uses a DispatcherServlet to route requests to Controller
objects and then passes the ModelAndView results to the rendering layer.
public interface Controller {
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception;
}
In Spring MVC the integration plugin points are the Controllers.
Click uses higher level design constructs focusing on Pages and Controls. Click uses its
own ClickServlet for dispatching requests to Pages and Controls,
which are Click's plugin points.
-
17. Does Click support JSP?
-
Click fully supports JSP pages.
JSP Pages can be automatically loaded, like Velocity templates, or
can be explicitly defined in the click.xml file.
<pages package="com.mycorp.pages"/>
<page path="customers-table.jsp" class="CustomersTable"/>
</pages>
The page's model data values are automatically added to the request as
attributes so they are available in the JSP. Other Click values added
as request attributes include:
- context -
the Servlet context path, e.g. /mycorp
- format -
the Format
object for formatting the display of objects
- forward -
the page JSP resource (.jsp file)
- messages -
the MessagesMap adaptor
for the Page getMessage()
method
- path - the mapped request path
of the page. Note this will have a .htm not a .jsp extension
-
18. How can I render PDF and Excel documents?
-
By making use of the Direct Rendering
support you can render directly to the servlet response and bypass the page
template rendering.
In order to bypass the Page template rendering you must set
the Page path to null. If Click does not know the location of the
Page template, it won't render it. If you do not set the Page path to null,
Click will attempt to render the Page template which can lead to undesirable results.
Here is an example to render either a PDF or Excel document:
public MyPage extends Page {
/** The PDF report type request parameter. */
public static final String PDF = "pdf";
/** The Excel report type request parameter. */
public static final String EXCEL = "excel";
/**
* The Page#onGet renders the report to the servlet output stream.
*/
public void onGet() {
HttpServletResponse response = getContext().getResponse();
// report type is a request parameter which specifies either PDF or Excel
String reportType = getContext().getRequestParameter("reportType");
// Retrieve either a PDF or Excel document as an InputStream
InputStream inputStream = getInputStream(reportType);
// Set response headers
String mimeType = getMimeType(reportType);
response.setHeader("Content-Disposition", "attachment; filename=\"report.pdf\"");
response.setContentType(mimeType);
response.setHeader("Pragma", "no-cache");
OutputStream outputStream = null;
try {
outputStream = response.getOutputStream();
// Write out PDF Document to response stream
IOUtils.copy(inputStream, outputStream);
// By setting the Page path to null, we bypass template rendering
setPath(null);
} catch (IOException ioe) {
throw new RuntimeException(ioe);
} finally {
ClickUtils.close(outputStream);
}
}
/**
* This method should contain the logic to retrieve the report as either a PDF
* or Excel document.
*/
public InputStream getReport(String reportType) {
InputStream inputStream = null;
if (PDF.equals(reportType)) {
...
} else if (EXCEL.equals(reportType)) {
...
}
return inputStream;
}
/**
* This method returns the report mime type based on the specified report type.
*/
public String getMimeType(String reportType) {
if (PDF.equals(reportType)) {
return ClickUtils.getMimeType(".pdf");
} else if (EXCEL.equals(reportType)) {
return ClickUtils.getMimeType(".xls");
}
}
}
-
19. What is the performance of Click?
-
Click is fast.
When the Click framework processes a request it creates a relatively small
number of objects. These include a Page, a Context, a Format and a number of
Controls which in turn contain some Lists, Maps and Strings.
The allocation of small/moderate numbers of short lived objects by
modern JVMs is very, very fast. Please see the IBM article
Urban performance legends, revisited.
The amount of actual work Click does is pretty small.
The onProcess() methods traverse a list of Controls and do simple
operations.
The Control toString() methods can allocate large StringBuffers when
rendering tables, but forms rarely get larger than 4,000 characters.
When Click creates a new StringBuffer it attempts to determine the
maximum likely size to avoid additional memory allocation and arraycopy
operations.
There is not much reflection in Click at all. With reflection only really used by
the Control call back listeners:
okButton.setListener(this, "onOkClicked");
The next step in processing the request is rendering the response.
Velocity is largely responsible for this step.
Velocity is also fast.
While hard performance numbers are difficult to come by in this area,
until recently Velocity was considered to be faster than JSP.
However, recent discussions on Velocity mail lists indicate that JSP
compilers have improved to the point where JSP has a small performance lead over
Velocity. What ever the case, JSP is very fast and so is Velocity.
-
20. How do I unit test Click pages?
-
It is generally recommended that you don't write JUnit style automated unit
tests for Click pages as the cost to benefit ratio is quite poor.
If you have complex business logic in an Click page you should refactor this
code into a business level service class which you can readily unit test and
reuse in multiple places.
If you still need to write unit tests for your Click pages, please read the
documentation on the
MockContainer and
MockContext classes.
-
21. How do I deploy Click resources in restricted environments?
-
Often times one need to run Click applications in restricted environments.
Examples include:
- WAR/EAR is not unpacked - common with WebLogic and Websphere servers
- File system permissions are restricted
- Hosting applications on Google App Engine
Click works perfectly fine in these environments. The only issue one might
encounter is Click's auto-deploy feature where static resources are copied
to the webapp root directory at application startup. In restricted environments
it might not be possible for Click to deploy its resources.
Please see the user-guide section, Deploying resources in a restricted environment,
for various solutions.
-
22. Why doesn't Click use Commons Logging / Log4J for logging?
-
Click by default does not use Commons Logging / Log4J to avoid the class
loader and configuration issues which often occur with these framework, and
instead default to System.out using the ConsoleLogger.
Click provides support for configurable LogServices and provides
JdkLogService and Log4JLogService classes in Click Extras.
-
23. Why doesn't Click use FreeMarker instead of Velocity as the default template engine?
-
FreeMarker is a powerful templating engine which was evaluated along side
Velocity for use in Click. While FreeMarker has many sophisticated
features Velocity lacks, Velocity was chosen as the default engine because
it is easier to learn and doesn't use an XML style markup syntax.
Please note however that Click provides support for FreeMarker with the
FreemarkerTemplateService in Click Extras.
-
24. Can Click be used to develop Portlet applications?
-
Unfortunately no. Click is built on top of the Servlet specification which is
incompatible with the Portlet specification. However in a future Click release
the Portals Bridges
project could be leveraged to allow Click applications to run inside a Portlet
container.
-
25. Why develop a new Web Application Framework?
-
Because the existing frameworks did not meet my needs. Struts doesn't really do much,
while Tapestry is too complicated.
For a more comprehensive answer please see Why Click.

or: How To Write Efficient Code
and ground truths.
"top-down"
or "bottom-up" design?
Top-Down:
— choose a high-level architecture;
— choose what classes will be in the codebase;
— draw some diagrams;
Bottom-Up:
— how the inner loop in my code will work?
— what is the data layout in memory?
— what bytes are read/written and where?
ClickHouse was developed from a prototype,
implemented in year 2008
that was intended to solve just a single task:
— to filter and aggregate data as fast as possible.
— in other words, just to do GROUP BY.
http://highscalability.com/blog/2017/9/18/evolution-of-data-structures-in-yandexmetrica.html
1. What are the basic numbers (throughput, latency, volume...)
of our hardware (CPU, RAM, SSD, HDD, network...)
on what operations?
2. What are the data structures we use?
and how the work with our hardware?
3. and do some basic math...
Example:
— we will do GROUP BY in memory;
— will put all data in a hash table;
— if the hash table is large, it will not fit in L3 cache of CPU;
— if the values of GROUP BY keys are not distributed locally,
then we have L3 cache miss for every row in a table;
— L3 cache miss has 70..100 ns latency;
How many keys per second we can process?
Example:
SELECT rand() % 10000000 AS k
FROM system.numbers_mt
GROUP BY k
175.52 million rows/s.
L3 cache miss has throughput of 40 million ops/sec. on a single CPU core
and ~ 500 million. ops/sec*. on 32 hyper-threading CPU cores
(Xeon E5-2650v2).
Never mess up latency and throughput!
* but we have just 175 million rows per second. Is ClickHouse slow?
If you need maximum performance
— then interfaces in the code are determined by algorithms!
Example: substring search:
— in C: strstr, memmem;
— in C++: std::search, std::string::find.
But these functions are slow! (in some usage scenario).
Substring Search:
void * memmem(const void * haystack, size_t haystacklen,
const void * needle, size_t needlelen);
— there is no separate initialization routine;
— required to be reentrable — cannot allocate memory.
But what if we search a single needle in 1 000 000 different haystacks?
Searcher searcher(needle);
for (const auto & haystack : haystacks)
searcher.search(haystack);
Substring Search:
void * memmem(const void * haystack, size_t haystacklen,
const void * needle, size_t needlelen);
If we search a single needle in 1 000 000 different haystacks,
then neither of strstr, memmem, std::search, std::string::find
will work fast, because their interface is not suitable.
And without changing the interface you cannot make them fast.
If you know your task better.
— substring search;
(but some smart guys have already implemented std::search)
— array sorting;
(but some smart guys have already implemented std::sort)
— hash table;
(but some smart guys have already implemented std::unordered_map)
Substring Search:
— exact or approximate search?
— one or multiple substrings?
— the set of substrings is explicit or specified by a language?
— substrings are rather short or long?
— substring is a sequence of
bytes / unicode code points / characters with custom collation / words?
— a search in predefined text or the text is not known in advance?
— is located in memory completely or available as a stream of data?
— with strong guarantees on time or not?

What ClickHouse is using:
— Volnitsky algorithm when needle is constant;
— SIMD optimized brute-force for non-constant needle;
— variation of Volnitsky algorithm for a set of constant needles;
— re2 and hyperscan for regular expressions.
Sorting
— array of numbers / tuples / strings / structures?
— available completely in RAM?
— with comparisons / 3-way comparisons /
parallel comparisons / by radix?
— direct / indirect (not sort, obtain a permutation)?
— stable / non-stable?
— full / partial / n-th element?
— finish sorting / merging / incomplete sorting?
ClickHouse is using pdqsort and radix sort,
... but it's not perfect, must rewrite.
Hash Table (my favorite)
— the choice of hash function;
— memory layout: open-addressing vs. chaining;
— small or big values;
— support for non-moveable values;
— memory layout: one array for keys and values or separate arrays;
— collision resolution algorithm;
— algorithm for values removal;
— fill factor; when and how to resize;
— how to move values around on resize;
— fast probing with bitmaps;
— inline placement of string keys;
— prefetch and batching;
We use the best* hash table in ClickHouse.
* the best for our needs.
* not a single but multiple different hash tables.
* and we constantly trying to do better:
https://github.com/ClickHouse/ClickHouse/pull/5417
— Add StringHashMap to optimize string aggregation by Amos Bird.
If you know your task better.
— substring search;
— array sorting;
— hash table;
...
— allocating memory (malloc);
— copying bytes around (memcpy);
In ClickHouse we use:
— chinese memcpy:
https://github.com/ClickHouse/ClickHouse/tree/master/libs/libmemcpy
— a special memcpy to gather short pieces of memory:
memcpySmallAllowReadWriteOverflow15
or grab the best!
If someone on the internet said that "my algorithm is the best"
— use that algorithm in ClickHouse.
... and probably throw away if it isn't the best.
Example: simdjson — adopted, still using.
Example: mimalloc — tried, throwed away.
Trivial example:
WHERE str LIKE '%hello%world!%'
— regular expression (re2)
but substring search for "world!" before;
WHERE str LIKE '%hello%'
— substring search;
WHERE str LIKE 'hello%'
— prefix comparison.
But even MySQL has similar optimization.
Specialization For the Data Types (example: GROUP BY):
using AggregatedDataWithoutKey = AggregateDataPtr;
...UInt8Key = FixedHashMap<UInt8, AggregateDataPtr>;
...UInt16Key = FixedHashMap<UInt16, AggregateDataPtr>;
...UInt64Key = HashMap<UInt64, AggregateDataPtr, HashCRC32<UInt64>>;
...StringKey = HashMapWithSavedHash<StringRef, AggregateDataPtr>;
...Keys128 = HashMap<UInt128, AggregateDataPtr, UInt128HashCRC32>;
...Keys256 = HashMap<UInt256, AggregateDataPtr, UInt256HashCRC32>;
...UInt64KeyTwoLevel = TwoLevelHashMap<UInt64, AggregateDataPtr, HashCRC32<UInt64>>;
...StringKeyTwoLevel = TwoLevelHashMapWithSavedHash<StringRef, AggregateDataPtr>;
...Keys128TwoLevel = TwoLevelHashMap<UInt128, AggregateDataPtr, UInt128HashCRC32>;
...Keys256TwoLevel = TwoLevelHashMap<UInt256, AggregateDataPtr, UInt256HashCRC32>;
...UInt64KeyHash64 = HashMap<UInt64, AggregateDataPtr, DefaultHash<UInt64>>;
...StringKeyHash64 = HashMapWithSavedHash<StringRef, AggregateDataPtr, StringRefHash64>;
...Keys128Hash64 = HashMap<UInt128, AggregateDataPtr, UInt128Hash>;
...Keys256Hash64 = HashMap<UInt256, AggregateDataPtr, UInt256Hash>;
Specialization for different amounts of data.
Example: quantileTiming function:
— less than 64 values — flat array in memory arena;
— less than 5670 values — flat array in heap memory;
— more — a histogram with custom buckets.
(QuantileTiming.h)
Example: uniqCombined function:
— flat array;
— hash table;
— HyperLogLog.
(CombinedCardinalityEstimator.h)
How to choose the data structure?
— find out what it implements, needed and unneeded.
Trivial example: std::string:
— implements memory management by itself.
— allow to modify a string,
e.g. append one more character.
— tracks string size by its own.
Trivial example: how to implement GROUP BY?
Option 1:
— sort the array by keys;
— then iterate through it,
and calculate aggregate functions for consecutive identical keys.
Option 2:
— put all keys into a hash table;
— when the key is found again,
update the states of aggregate functions.
Answer: option 2 is better; but if the data is almost sorted then better to finish sorting and apply option 1; but if the data doesn't fit in memory, partition it by buckets and then option 2.

This is a page for manually checking the visual output of the postcss-gradient-transparency-fix
plugin.
At some future point this might get run through automated visual regression tests, but for now it’s just a sanity check.
- If this page is opened in Safari, it shows the gradients before/after fixing.
There should be a huge difference in the gradients in each pair.
- If this page is opened in any other browser, each test should show two identical gradients.
If they’re not identical, the plugin is wrong.


Banks will get just a sliver of Alibaba's $11.2 billion share sale
The average fee earned on the 10 largest listings in Hong Kong is 1.76%
by Julia Fioretti | BloombergAlibaba Group Holding Ltd.’s $11.2 billion Hong Kong share sale may be set to swell the tech giant’s cash pile but the banks are getting just a tiny percentage of that.
Alibaba will pay the banks that underwrote the listing $28.1 million, representing just 0.25% of the deal value, according to the prospectus lodged with the U.S. Securities and Exchange Commission. That is the lowest fee in percentage terms paid to banks out of the 10 largest listings in Hong Kong, data compiled by Bloomberg show. Alibaba could pay them as much as $32.3 million if an over-allotment option of 75 million shares is exercised in full.
Credit Suisse Group AG and China International Capital Corp. were the joint sponsors of the share sale. Citigroup Inc., JPMorgan Chase & Co. and Morgan Stanley were joint global coordinators.
The average fee earned on the 10 largest listings in Hong Kong is 1.76%, with the highest being the 2.5% paid by the likes of Bank of China Ltd. and China Construction Bank Corp. Budweiser Brewing Company APAC Ltd. -- which completed Hong Kong’s second-biggest listing this year after Alibaba -- paid its banks 1.5% of the IPO proceeds.
Issuers typically pay banks about 2% to 3% of the proceeds for initial public offerings in Hong Kong, the bulk of which goes to the sponsors. Banks also split the 1% brokerage fee paid by investors. The average percentage fee for listings in Hong Kong this year is 4.5%, data compiled by Bloomberg show.
Alibaba’s listing is the largest equity offering in the financial hub since 2010, making it a particularly coveted deal for investment banks, who have seen fees compressed as competition increases.
Despite the small percentage the Alibaba fee represents, the $28.1 million is still good money for the banks in a year where until recently IPO volumes in Hong Kong were down some 40% from a year earlier. The banks will also take home the 1% brokerage fee, bringing their total compensation to 1.25% of the proceeds, or about $140 million.
However, it is a far cry from the $300 million banks earned for working on Alibaba’s $25 billion New York IPO in 2014, although that would have required a lot more work as investors were less familiar with the company.
CICC was allocated the largest number of Alibaba shares to underwrite -- 160 million -- followed by Credit Suisse, which underwrote 127.5 million, the prospectus shows. In it, Alibaba said it would pay HK$0.44 per share in underwriting fees.

What are particle detectors?
Particle detectors can be thought of as high-tech cameras that take “photographs” of phenomena that physicists want to study. These phenomena may originate in nuclear decays, cosmic radiation or interactions in a particle accelerator. Let us take a closer look at detectors such as those used at the LHC, which consist of layers of specialized components each designed to specific particles and identify certain properties.
The tracker helps us to calculate the momentum of charged particles. They bend due to magnetic field. The smaller the curve radius is, the less momentum the particle had. We also differentiate positive and negative particles based on the direction of the track.
The Electromagnetic Calorimeter (ECAL) is used to measure the energies of electrons and photons.
The Hadron Calorimeter (HCAL) is used to measure the energy of hadrons, composite particles that made of quarks and gluons. Some examples of hadrons are protons, neutrons and pions. It also helps us detect neutrinos but indirectly. Energy needs to be conserved, so if we observe missing enery, this indicates neutrinos or as-yet-undiscovered particles flew through the detector.
Particle detectors require magnets with very strong magnetic fields in order to sufficiently bend particles flying with high momenta. Trajectories of particles with higher momenta bend less, while those with lower momenta bend a lot more. The magnetic field also helps distinguish between positively and negatively charged particles: they bend in opposite directions in the same magnetic field.
Muons are charged particles that are just like electrons and positrons, but are 200 times more massive. Because they can penetrate several metres of iron without interacting, the muon chamber is placed at the very edge of the detector where they are the only particles likely to register a signal.

 To make it easy, I have used chard, in case you don’t fancy going out to gather dandelions or sea kale.
Drain the beans, cover with fresh water and bring to the boil. Turn down to a simmer and cook for 1½-2 hours until the beans are just tender.
Gently soften the onion and garlic in 2 tablespoons of the olive oil for 5 minutes. When soft, stir in the paprika, tomato purée, chopped tomatoes, 100ml/3½fl oz water, salt and pepper.
Bring to the boil then reduce to a simmer and cook for 30 minutes. Stir in the chard and take off the heat.
Preheat the oven to 160C/140C Fan/Gas 3.
When the beans are cooked, drain them and mix with the tomato and chard sauce, adding a further 2 tablespoons of olive oil and the chopped herbs.
Transfer the beans to a casserole pan, drizzle with the remaining olive oil and bake for 35–40 minutes until the beans are tender and the sauce thickened and bubbling. Serve hot, warm or at room temperature.

Raspberry Pi 3 Supercomputer Heatsink Requirements
In what follows we will calculate the required thermal impedance of the heatsinking mechanism for the Raspberry Pi 3 Supercomputer. From previous calculations, it was observed that the Junction to Ambient Thermal Impedance of the CPU was about 32 C/W. Our goal is maintain the CPU temperature below 80C in order to prevent throttling of the CPU's clock rate by the built-in thermal governor.
1 Power Supply
2 Current Draws
3 Temperatures
4 Power Consumptions
5 Thermal Impedance Estimate of CPU (case to ambient) [deg C/W]
6 Thermal Impedance Estimate of CPU (junction to case)
7 Thermal Impedance Estimate of CPU (junction to ambient) [deg C/W]
8 Calculation of Heatsink Thermal Impdedance Requirements
In what follows, we will calculate the required thermal impedance of the heatsink. Under heavy load, the Raspberry Pi 3 is consuming 3.9W. We will assume that all of this is consumed by the CPU. Under these conditions, the temperature rise of the junction is:
Temperature rise of junction due to power dissipation across Junction to Ambient Thermal Impedance [deg C]
| (%i35) | T_rise_heavy_load_RthJA: P_RPi3_4_core_heavy_load * Theta_JA_RPI3_CPU; |
The portion of junction temperature rise due to the junction to case thermal impedance is:
Temperature rise of junction due to power dissipation across the Junction to Case Thermal Impedance [deg C]
| (%i36) | T_rise_heavy_load_RthJC: P_RPi3_4_core_heavy_load * Theta_JC_RPi3_CPU; |
Define the maximum junction temperature that we will allow to prevent thermal throttling of CPU clock rate. We will arbitrarily set the maximum temperature to 75C, to allow a 10C margin under 85C for manufacturing tolerances.
Maximum allowed junction temperature [deg C]
| (%i37) | T_junction_allowed_max: 75; |
The maximum allowed temperature rise is: [deg C]
| (%i38) | T_rise_allowed_max: T_junction_allowed_max - T_rise_heavy_load_RthJC; |
This temperature rise has to occur while dissipating 3.9W, which implies that the thermal impedance of the heatsink must be:
Thermal Impedance of Heatsink (Case to Ambient) [C/W]
| (%i39) | R_theta_heatsink_ambient: T_rise_allowed_max / P_RPi3_4_core_heavy_load; |
