pidgin(1) pidgin(1) Ri. NAME pidgin - Instant Messaging client SYNOPSIS pidgin [options] DESCRIPTION pidgin is a graphical modular messaging client based on libpurple which is capable of connecting to AIM, MSN, Yahoo!, XMPP, ICQ, IRC, SILC, Nov‐ ell GroupWise, Lotus Sametime, Zephyr, Gadu-Gadu, and QQ all at once. It has many common features found in other clients, as well as many unique features. Pidgin is not endorsed by or affiliated with America Online, ICQ, Microsoft, or Yahoo. Pidgin can be extended by plugins written in multiple programming lan‐ guages and controlled through DBus or purple-remote. OPTIONS The following options are provided by Pidgin using the standard GNU com‐ mand line syntax: -c, --config=DIR Use DIR as the directory for config files instead of ~/.purple. -d, --debug Print debugging messages to stdout. These are the same debugging messages that are displayed in the Debug Window. -f, --force-online Try to be online even if the network is reported (by Windows, or NetworkManager on Linux) to be unavailable. -h, --help Print a summary of command line options and exit. -m, --multiple Allow multiple instances of Pidgin to run. -n, --nologin Don't automatically login when Pidgin starts. Sets the global status to Offline. -l, --login[=NAME,NAME,...] Enable the comma-separated list of accounts provided, disabling all other accounts. If the user does not specify such a comma- separated list, the first account in accounts.xml will be enabled. -v, --version Print the current version and exit. TERMS Pidgin uses a few terms differently from other applications. For conve‐ nience they are defined here: Buddy List The list of other users who the user wants to see status informa‐ tion for and have quick access to for messaging. Buddy A user who has been added to the Buddy List. Contact A grouping of more than one buddy who are all the same person. A contact may contain buddies from any protocol and may contain as many buddies as the user desires. Contact arrangements are stored locally only. Alias A private "nickname" that may be set for Buddies or the user him‐ self. On some protocols, aliases are saved on the server but not visible to other users. On other protocols, aliases are saved only locally. Protocol A messaging service. AIM, XMPP, MSN, Zephyr, etc. are protocols. Others may call these "service types," "account types," "ser‐ vices," and so on. BUDDY LIST The Buddy List window is Pidgin's main interface window. Using this win‐ dow a user can see which of his/her buddies is online, away, idle, etc. The user can also add buddies to and remove buddies from the buddy list. The Buddy List window contains a list of the user's buddies who are online and have allowed the user to be notified of their presence. The icon to the left of each buddy indicates the buddy's current status. Double clicking a buddy will open a new Conversation window. Right clicking will pop up a menu: Get Info Retrieves and displays information about the buddy. This informa‐ tion is also known as a Profile. IM Opens a new Conversation window to the selected buddy. Send File Sends a file to the selected buddy (only available on protocols that support file transfer). Add Buddy Pounce A Buddy Pounce is a configurable automated action to be performed when the buddy's state changes. This will open the Buddy Pounce dialog, which will be discussed later. View Log Pidgin is capable of automatically logging messages. These logs are either plain text files (with a .txt extension) or html files (with a .html extension) located under the ~/.purple/logs direc‐ tory. This menu command will display Pidgin's log viewer with logs loaded for that buddy or chat. Alias Create an alias for this buddy. This will show an editable text field where the buddy's name was displayed. In this field one can give this buddy an alternate, more friendly name to appear on the buddy list and in conversations. For example, if a buddy's name was jsmith1281xx and his real name was 'John Q. Smith,' one could create an alias as to identify the buddy by his common name. The remainder of the menu will consist of protocol specific commands. These commands vary depending on the protocol. Status Selector At the bottom of the Buddy List is a status selector which allows one to change his/her status. This will be discussed further in the STATUS MESSAGES section below. ACCOUNT EDITOR The account editor consists of a list of accounts and information about them. It can be accessed by selecting Manage from the Accounts menu. Clicking Delete will delete the currently selected account. Clicking Add or Modify will invoke a Modify Account window. Here, the user can add or alter account information. When creating a new account, the user will submit a username and password. The user will also choose the protocol for the account. If Remember Password is chosen, the password will be saved in Pidgin's ~/.purple/accounts.xml configuration file. If Enabled is checked in the accounts dialog, this account will follow the status currently selected in the status selector. If it is not checked, the account will always be offline. Each protocol has its own specific options that can be found in the mod‐ ify screen. PREFERENCES All options take effect immediately. Interface Show system tray icon Specifies when to show a Pidgin icon in the notification area of the user's panel (commonly referred to as the System Tray). Hide new IM conversations Specifies when to hide new IM messages. Messages will queue under the specified condition until shown. Clicking the Pidgin icon in the notification area or system tray will display the queued mes‐ sages. An icon also appears in the buddy list's menu bar; this icon may also be used to display queued messages. Show IMs and chats in tabbed windows When checked, this option will cause IM and chat sessions to appear in windows with multiple tabs. One tab will represent one conversation or chat. Where tabs are placed will be dictated by the preferences below. Show close buttons on tabs When checked, this option will cause a clickable "U+2715 MULTIPLI‐ CATION X" unicode character to appear at the right edge of each tab. Clicking this will cause the tab to be closed. Placement Specifies where to place tabs in the window. Some tab orienta‐ tions may allow some users to fit more tabs into a single window comfortably. New conversations Specifies under which conditions tabs are placed into existing windows or into new windows. For a single window, select Last created window here. Conversations Enable buddy icon animation If a buddy's icon happens to be animated, this option will enable the animation, otherwise only the first frame will be displayed. Notify buddies that you are typing to them Some protocols allow clients to tell their buddies when they are typing. This option enables this feature for protocols that sup‐ ports it. Default Formatting Allows specifying the default formatting to apply to all outgoing messages (only applicable to protocols that support formatting in messages). Smiley Themes Allows the user to choose between different smiley themes. The "none" theme will disable graphical emoticons - they will be displayed as text instead. The Add and Remove buttons may be used to install or uninstall smiley themes. Themes may also be installed by dragging and dropping them onto the list of themes. Sounds Method Lets the user choose between different playback methods. The user can also manually enter a command to be executed when a sound is to be played(%s expands to the full path to the file name). Sounds when conversation has focus When checked, sounds will play for events in the active conversa‐ tion if the window is focused. When unchecked, sounds will not play for the active conversation when the window is focused. Enable Sounds Determines when to play sounds. Sound Events Lets the user choose when and what sounds are to be played. Network STUN server This allows specifying a server which uses the STUN protocol to determine a host's public IP address. This can be particularly useful for some protocols. Autodetect IP address When checked, causes Pidign to attempt to determine the public IP address of the host on which Pidgin is running and disables the Public IP text field listed below. Public IP If Autodetect IP address is disabled, this field allows manually specifying the public IP address for the host on which Pidgin is running. This is mainly useful for users with multiple network interfaces or behind NATs. Manually specify range of ports to listen on Specify a range ports to listen on, overriding any defaults. This is sometimes useful for file transfers and Direct IM. Proxy Server The configuration section to enable Pidgin to operate through a proxy server. Pidgin currently supports SOCKS 4/5 and HTTP prox‐ ies. Browser Browser Allows the user to select Pidgin's default web browser. Firefox, Galeon, Konqueror, Mozilla, Netscape and Opera are supported natively. The user can also manually enter a command to be exe‐ cuted when a link is clicked (%s expands to the URL). For exam‐ ple, xterm -e lynx "%s" will open the link with lynx. Open link in Allows the user to specify whether to use an existing window, a new tab, a new window, or to let the browser to decide what to do when calling the browser to open a link. Which options are avail‐ able will depend on which browser is selected. Logging Log format Specifies how to log. Pidgin supports HTML and plain text, but plugins can provide other logging methods. Log all instant messages When enabled, all IM conversations are logged. This can be over‐ ridden on a per-conversation basis in the conversation window. Log all chats When enabled, all chat conversations are logged. This can be overridden on a per-conversation basis in the conversation window. Log all status changes to system log When enabled, status changes are logged. Status / Idle Report idle time Determines under which conditions to report idle time. Based on keyboard and mouse use uses keyboard and mouse activity to deter‐ mine idle time. From last sent message uses the time at which the user last sent a message in Pidgin to determine idle. Never dis‐ ables idle reporting. Auto-reply Determines when to send an auto-reply on protocols which support it (currently only AIM). Change status when idle When enabled, this uses the Minutes before becoming idle and Change status to preferences described below to set status on idle. Minutes before becoming idle Specifies how many minutes of inactivity are required before con‐ sidering the user to be idle. Change status to Specifies which "primitive" or "saved" status to use when setting status on idle. Use status from last exit at startup If this is checked, Pidgin will remember what status was active when the user closed Pidgin and restore it at the next run. When disabled, Pidgin will always set the status selected in Status to apply at startup at startup. Status to apply at startup When Use status from last exit at startup is disabled, this speci‐ fies which "primitive" or "saved" status to use at startup. CONVERSATIONS When starting a new conversation, the user is presented with the Conver‐ sation window. The conversation appears in the upper text box and the user types his/her message in the lower text box. Between the two is a row of options, represented by icons. Some or all buttons may not be active if the protocol does not support the specific formatting. From left to right: Font This menu provides font control options for the current conversa‐ tion. Size, style, and face may be configured here. Insert This menu provides the ability to insert images, horizontal rules, and links where the protocol supports each of these features. Smile! Allows the insertion of graphical smileys via the mouse. This button shows the user a dialog with the available smileys for the current conversation. CHATS For protocols that allow it, Chats can be entered through the Buddies menu. Additional features available in chat, depending on the protocol are: Whisper The text will appear in the chat conversation, but it will only be visible to the sender and the receiver. Invite Invite other people to join the chat room. Ignore Ignore anything said by the chosen person Set Topic Set the topic of the chat room. This is usually a brief sentence describing the nature of the chat--an explanation of the chat room's name. Private Message (IM) Send a message to a specific person in the chat. Messages sent this way will not appear in the chat window, but instead open a new IM conversation. STATUS MESSAGES Most protocols allow for status messages. By using status messages, a user can leave an informative message for others to see. Status and sta‐ tus messages are configured via the status selector at the bottom of the Buddy List window. By default the menu shown here is divided into sec‐ tions for "primitive" status types, such as Available, Away, etc.; a few "popular" statuses (including "transient" statuses) which have been recently used, and a section which shows New Status... and Saved Sta‐ tuses... options for more advanced status manipulation.  Examples of primitive statuses would be Available, Away, Invisi‐ ble, etc. A primitive status can be used to create a Transient Status or a Saved Status, both explained below. Essentially, primitive statuses are building blocks of more complicated sta‐ tuses. Transient Statuses When one of the statuses from the topmost section of the status selector's menu is selected, this creates a transient, or tempo‐ rary, status. The status will show in the "popular statuses" sec‐ tion in the menu until it has not been used for a sufficiently long time. A transient status may also be created by selecting New Status... from the status selector's menu, then clicking Use once the user has entered the message. Saved Statuses Saved statuses are permanent--once created, they will exist until deleted. Saved statuses are useful for statuses and status mes‐ sages that will be used on a regular basis. They are also useful for creating complex statuses in which some accounts should always have a different status from others. For example, one might wish to create a status called "Sleeping" that has all accounts set to "Away", then create another status called "Working" that has three accounts set to "Away" and another account set to "Available." New Status Window When the user selects New Status... from the status selector menu, Pidgin presents the user with a dialog asking for status-related information. That information is discussed below: Title - The name of the status that will appear in the status selctor's menu. If the user clicks the Save or Save & Use button, this name will also be shown in the Saved Status Window. The title should be a short description of the status. Status - The type of status being created, such as Available, Away, etc. Message - The content of the status message. This is what is vis‐ ible to other users. Some protocols will allow formatting in some status messages; where formatting is not supported it will be stripped to the bare text entered. Use a different status for some accounts - This allows the cre‐ ation of complex statuses in which some accounts' status differs from that of other accounts. To use this, the user will click the expander to the left of the text, then select individual accounts which will have a different status and/or status message. When the user selects an account, Pidgin will present another status dialog asking for a status and a message just for the selected account. Saved Status Window When the user selects Saved Statuses... from the status selector's menu, Pidgin presents a dialog that lists all saved statuses. "Transient" statuses, discussed above, are NOT shown here. This window provides the ability to manage saved statuses by allowing the creation, modification, and deletion of saved statuses. The Use, Modify, and Delete buttons here allow operation on the status selected from the list; the dd button allows creation of a new saved status, and the Close button closes the window. BUDDY POUNCE A Buddy Pounce is an automated trigger that occurs when a buddy returns to a normal state from an away state. The Buddy Pounce dialog box can be activated by selecting the Buddy Pounce option from the Tools menu. From this dialog, new pounces can be created with the Add button and existing pounces can be removed with the Delete button. A pounce can be set to occur on any combination of the events listed, and any combination of actions can result. If Pounce only when my status is not Available is checked, the pounce will occur only if the user is set to a non-available status, such as invisible, do not disturb, away, etc. If Recurring is checked, the pounce will remain until removed by the Delete button. CUSTOM SMILIES Pidgin 2.5.0 introduced support for custom smilies on those protocols for which interested contributors have developed support. The custom smiley manager can be accessed by selecting Smiley from the Tools menu. From here, custom smilies may be added, edited, or deleted by clicking the Add, Edit, or Delete buttons, respectively. During a conversation with another user, that user's custom smileys may be added to the user's own custom smiley list directly from the conversa‐ tion window by right-clicking the new custom smiley and selecting Add Custom Smiley... PLUGINS Pidgin allows for dynamic loading of plugins to add extra functionality to Pidgin. See plugins/HOWTO or http://developer.pidgin.im/wiki/CHowTo for information on writing plugins. The plugins dialog can be accessed by selecting Plugins from the Tools menu. Each plugin available appears in this dialog with its name, ver‐ sion, and a short summary of its functionality. Plugins can be enabled with the checkbox beside the name and short description. More informa‐ tion on the currently selected plugin is available by clicking the expander beside the text Plugin Details. If the selected plugin has preferences or configuration options, the Configure Plugin button will present the plugin's preferences dialog. PERL Pidgin allows for plugins to be written in the perl scripting language. See Perl Scripting HOWTO in the Pidgin documentation for more information about perl scripting. TCL Pidgin allows for plugins to be written in the Tcl scripting language. See plugins/tcl/TCL-HOWTO for more information about Tcl scripting. D-Bus Pidgin allows for interaction via D-Bus. Currently very little documen‐ tation about this interaction exists.

s6-portable-utils
Software
skarnet.org
The s6-head program
s6-head prints the first lines of its input files.
Interface
s6-head [ -S ] [ -1..9 | -n lines | -c chars ] file...
s6-head acts as the generic
head utility.
Extra options
- -S : safe mode. s6-head stops reading its input files right after
getting all the lines it needs. The rest of the stream can then be handled by other
utilities without any data loss.
- -1..9 : equivalent to -n 1 .. -n 9.
- -c chars : cuts after chars characters instead
of lines lines.
Posixness
s6-head is suitable as a Single Unix
head
program.

Creating a RESTful Web Service with Spring Boot
| 作者 | Hadi Hariri, Edoardo Vacchi, Sébastien Deleuze |
| 源代码 | On GitHub |
Kotlin works quite smoothly with Spring Boot and many of the steps found on the Spring Guides for creating a RESTful service can be followed verbatim for Kotlin. There are some minor differences however when it comes to defining the Gradle configuration and the project layout structure, as well as the initialization code.
In this tutorial we'll walk through the steps required. For a more thorough explanation of Spring Boot and RESTful services, please see Building a RESTful Web Service.
Note that all classes in this tutorial are in the org.jetbrains.kotlin.demo
package.
Defining the project and dependencies
In this tutorial we're going to be using Gradle but the same can be accomplished using either IntelliJ IDEA project structure or Maven. For details on setting up Gradle to work with Kotlin, see Using Gradle.
The Gradle file is pretty much standard for Spring Boot. The only differences are the structure layout for source folders for Kotlin, the required Kotlin dependencies and the kotlin-spring Gradle plugin (CGLIB proxies used for example for @Configuration
and @Bean
processing require open
classes).
buildscript {
ext.kotlin_version = '1.2.41' // Required for Kotlin integration
ext.spring_boot_version = '1.5.4.RELEASE'
repositories {
jcenter()
}
dependencies {
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" // Required for Kotlin integration
classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version" // See https://kotlinlang.org/docs/reference/compiler-plugins.html#kotlin-spring-compiler-plugin
classpath "org.springframework.boot:spring-boot-gradle-plugin:$spring_boot_version"
}
}
apply plugin: 'kotlin' // Required for Kotlin integration
apply plugin: "kotlin-spring" // See https://kotlinlang.org/docs/reference/compiler-plugins.html#kotlin-spring-compiler-plugin
apply plugin: 'org.springframework.boot'
jar {
baseName = 'gs-rest-service'
version = '0.1.0'
}
repositories {
jcenter()
}
dependencies {
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" // Required for Kotlin integration
compile 'org.springframework.boot:spring-boot-starter-web'
testCompile('org.springframework.boot:spring-boot-starter-test')
}
Creating a Greeting Data Class and Controller
The next step is to create Greeting Data class that has two properties: id and a content
data class Greeting(val id: Long, val content: String)
We now define the GreetingController which serves requests of the form /greeting?name={value} and returns a JSON object representing an instance of Greeting
@RestController
class GreetingController {
val counter = AtomicLong()
@GetMapping("/greeting")
fun greeting(@RequestParam(value = "name", defaultValue = "World") name: String) =
Greeting(counter.incrementAndGet(), "Hello, $name")
}
As can be seen, this is again pretty much a one-to-one translation of Java to Kotlin, with nothing special required for Kotlin.
Creating the Application class
Finally we need to define an Application class. As Spring Boot looks for a public static main method, we need to define this in Kotlin. It could be done with the @JvmStatic annotation and a companion object but here we prefer using a top-level function defined outside Application class since it leads to more concise and clean code.
No need to mark the Application class as open since we are using the kotlin-spring Gradle plugin which does that automatically.
@SpringBootApplication
class Application
fun main(args: Array<String>) {
SpringApplication.run(Application::class.java, *args)
}
Running the application
We can now use the any of the standard Gradle tasks for Spring Boot to run the application. As such, running
./gradlew bootRun
the application is compiled, resources bundled and launched, allowing us to access is via the browser (default port is 8080)


Overview
Problem
The Science Center plaza is a very popular area, home to food trucks, students, and tourists. The Science Center Plaza also has a live stream video feed 24 hours per day, which you can check out here. However, can we use this data to make decisions, such as when to schedule events in the plaza?
Our project provides real-time crowd analytics with object detection of people and average interframe and intraframe metrics, such as number of people, group size, velocity, and location heatmap for a given time period. We analyze 700 hours of video and then use streaming to compare the real-time current analytics to the historical data for the corresponding time period in order to detect interesting events such as large groups of people or fast movement.
Big Data and Big Compute
This problem requires the use of multiple frameworks:
- Big Data: because we process 150 GB of low-resolution historical video.
- Big Compute/HPC: handling the throughput for streaming analytics of real-time science center plaza video feed
With the Big Data part of our solution, we have fine-grained data parallelism and a SPMD execution model, while with the Big Compute component, we have coarse-grained data and functional parallelism and a DAT execution model.
Data, Software, and Infrastructure
We continuously collected from the Science Center Plaza Webcam over the course of multiple weeks from 4/5/19 to 5/3/19.
The basic outline of our solutions is as follows. We begin by feeding our data through an object detection model to obtain bounding boxes identifying person locations. We then compute analytics such as number of people, velocities, group sizes, and locations based on bounding boxes. For historical analysis, we then perform some aggregation of these statistics over short periods of time. For streaming, we just directly work with the output analytics. After analytics computation is complete, we feed the results into a variety of visualizations.
Note that our basic features are use of Spark and GPU, and our advanced feature is use of TensorFlow for our ML model. Our advanced functionality, we had scheduling of deep learning jobs across 4 GPUs, an alert system comparing real-time analytics to historical data for the corresponding hour, and a variety of visualizations including interactive plots.
We use AWS EC2 GPU instances to run object detection, and Spark on AWS EMR to perform analytics computation.
See the implementation page for more details on our software and infrastructure.
Code and Data
Our code can be found on Github here.
Our data can be found on S3:
Visualizations
Check out more visualizations here! Through the use of deep convolution neural networks and big data platforms such as Spark, we are able to quantify some of the patterns in the Science Center. In the data, we are able to see:

Conclusions
Overall, we successfully used big data and big compute infrastructures combined with TensorFlow to develop analytics of real-time crowd dynamics compared to historical data for the Science Center Plaza.
We ran into a few challenges in the course of our work. First, Databricks was unhelpful in distributing TensorFlow model across GPUs, so we ended up using an AWS EC2 GPU instance (p3.8xlarge) with 4 GPUs for our object detection model evaluation instead. We also tried to do some data processing and cleaning in PySpark before computation, but the API was severely limited due to distribution requirements (i.e. difficult to associate data across columns, create arbitrary data, and work with multi-dimensional arrays). Our solution to this was to perform some preprocessing in plain Python. We discovered empirically that UDFs with 2-column inputs would not parallelize well (the cluster was reverting to using only 1 core on 1 executor), so we concatenated and flattened bounding box data for adjacent frames to compute successive-frame statistics (e.g., velocity) using a single row.
From these challenges, we learned that data format needs to be very carefully selected before loading it into a Spark Dataframe, and we need to be careful when developing how to compute analytics, and which metrics to compute in a distributed system (i.e. choice of UDF).
In the future, we might want to handle more than one camera for the streaming (if there were more cameras) and take advantage of GPU IO system with AWS (NV-Link).

| SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
java.lang.Object java.awt.GridBagLayout
public class GridBagLayout
The GridBagLayout
class is a flexible layout
manager that aligns components vertically and horizontally,
without requiring that the components be of the same size.
Each GridBagLayout
object maintains a dynamic,
rectangular grid of cells, with each component occupying
one or more cells, called its display area.
Each component managed by a GridBagLayout
is associated with
an instance of GridBagConstraints
. The constraints object
specifies where a component's display area should be located on the grid
and how the component should be positioned within its display area. In
addition to its constraints object, the GridBagLayout
also
considers each component's minimum and preferred sizes in order to
determine a component's size.
The overall orientation of the grid depends on the container's
ComponentOrientation
property. For horizontal left-to-right
orientations, grid coordinate (0,0) is in the upper left corner of the
container with x increasing to the right and y increasing downward. For
horizontal right-to-left orientations, grid coordinate (0,0) is in the upper
right corner of the container with x increasing to the left and y
increasing downward.
To use a grid bag layout effectively, you must customize one or more
of the GridBagConstraints
objects that are associated
with its components. You customize a GridBagConstraints
object by setting one or more of its instance variables:
GridBagConstraints.gridx
,
GridBagConstraints.gridy
gridx = 0
,
gridy = 0
. For horizontal left-to-right layout,
a component's leading corner is its upper left. For horizontal
right-to-left layout, a component's leading corner is its upper right.
Use GridBagConstraints.RELATIVE
(the default value)
to specify that the component be placed immediately following
(along the x axis for gridx
or the y axis for
gridy
) the component that was added to the container
just before this component was added.
GridBagConstraints.gridwidth
,
GridBagConstraints.gridheight
gridwidth
)
or column (for gridheight
)
in the component's display area.
The default value is 1.
Use GridBagConstraints.REMAINDER
to specify
that the component's display area will be from gridx
to the last cell in the row (for gridwidth
)
or from gridy
to the last cell in the column
(for gridheight
).
Use GridBagConstraints.RELATIVE
to specify
that the component's display area will be from gridx
to the next to the last cell in its row (for gridwidth
or from gridy
to the next to the last cell in its
column (for gridheight
).
GridBagConstraints.fill
GridBagConstraints.NONE
(the default),
GridBagConstraints.HORIZONTAL
(make the component wide enough to fill its display area
horizontally, but don't change its height),
GridBagConstraints.VERTICAL
(make the component tall enough to fill its display area
vertically, but don't change its width), and
GridBagConstraints.BOTH
(make the component fill its display area entirely).
GridBagConstraints.ipadx
,
GridBagConstraints.ipady
ipadx
pixels. Similarly, the height of
the component will be at least the minimum height plus
ipady
pixels.
GridBagConstraints.insets
GridBagConstraints.anchor
ComponentOrientation
property while absolute values
are not. Valid values are:
Absolute Values |
Relative Values |
|---|---|
GridBagConstraints.NORTH GridBagConstraints.SOUTH GridBagConstraints.WEST GridBagConstraints.EAST GridBagConstraints.NORTHWEST GridBagConstraints.NORTHEAST GridBagConstraints.SOUTHWEST GridBagConstraints.SOUTHEAST GridBagConstraints.CENTER (the default) |
GridBagConstraints.PAGE_START GridBagConstraints.PAGE_END GridBagConstraints.LINE_START GridBagConstraints.LINE_END GridBagConstraints.FIRST_LINE_START GridBagConstraints.FIRST_LINE_END GridBagConstraints.LAST_LINE_START GridBagConstraints.LAST_LINE_END |
GridBagConstraints.weightx
,
GridBagConstraints.weighty
weightx
) and column (weighty
),
all the components clump together in the center of their container.
This is because when the weight is zero (the default),
the GridBagLayout
object puts any extra space
between its grid of cells and the edges of the container.
The following figures show ten components (all buttons) managed by a grid bag layout. Figure 1 shows the layout for a horizontal, left-to-right container and Figure 2 shows the layout for a horizontal, right-to-left container.
| Figure 1: Horizontal, Left-to-Right | Figure 2: Horizontal, Right-to-Left |
Each of the ten components has the fill
field
of its associated GridBagConstraints
object
set to GridBagConstraints.BOTH
.
In addition, the components have the following non-default constraints:
weightx = 1.0
weightx = 1.0
,
gridwidth = GridBagConstraints.REMAINDER
gridwidth = GridBagConstraints.REMAINDER
gridwidth = GridBagConstraints.RELATIVE
gridwidth = GridBagConstraints.REMAINDER
gridheight = 2
,
weighty = 1.0
gridwidth = GridBagConstraints.REMAINDER
Here is the code that implements the example shown above:
import java.awt.*; import java.util.*; import java.applet.Applet; public class GridBagEx1 extends Applet { protected void makebutton(String name, GridBagLayout gridbag, GridBagConstraints c) { Button button = new Button(name); gridbag.setConstraints(button, c); add(button); } public void init() { GridBagLayout gridbag = new GridBagLayout(); GridBagConstraints c = new GridBagConstraints(); setFont(new Font("SansSerif", Font.PLAIN, 14)); setLayout(gridbag); c.fill = GridBagConstraints.BOTH; c.weightx = 1.0; makebutton("Button1", gridbag, c); makebutton("Button2", gridbag, c); makebutton("Button3", gridbag, c); c.gridwidth = GridBagConstraints.REMAINDER; //end row makebutton("Button4", gridbag, c); c.weightx = 0.0; //reset to the default makebutton("Button5", gridbag, c); //another row c.gridwidth = GridBagConstraints.RELATIVE; //next-to-last in row makebutton("Button6", gridbag, c); c.gridwidth = GridBagConstraints.REMAINDER; //end row makebutton("Button7", gridbag, c); c.gridwidth = 1; //reset to the default c.gridheight = 2; c.weighty = 1.0; makebutton("Button8", gridbag, c); c.weighty = 0.0; //reset to the default c.gridwidth = GridBagConstraints.REMAINDER; //end row c.gridheight = 1; //reset to the default makebutton("Button9", gridbag, c); makebutton("Button10", gridbag, c); setSize(300, 100); } public static void main(String args[]) { Frame f = new Frame("GridBag Layout Example"); GridBagEx1 ex1 = new GridBagEx1(); ex1.init(); f.add("Center", ex1); f.pack(); f.setSize(f.getPreferredSize()); f.show(); } }

--- title: "The most important RFCs to understand HTTP/3 and QUIC" subtitle: "A non-comprehensive collection of specifications related to HTTP and the underlying security and transport-layer protocols" date: "2022-08-24" lastupdate: "2022-09-01" permalink: "/rfc-collection-http3-quic.html" ogimg: "og-rfc.jpg" ftimg: "ft-rfc.jpg" ---
The RFC (Request for Comments) Series is a numbered collection of technical specifications that standardize many of the procedures and protocols used in internet-based systems, including the communication protocols of the Internet Protocol Suite, e.g. HTTP, QUIC, UDP, TCP, and others.
While the RFC Series is available for anyone to peruse, and each RFC has its own number, it's not always easy to find all the RFCs related to a particular subject.
The catalog below includes the most important RFCs related to the recently published HTTP/3 and QUIC protocols, the previous versions of HTTP, and the underlying transport-layer and security protocols (QUIC, UDP, and TCP for transport and TLS for security).
---Note that this is not a comprehensive list, and there may exist other relevant specifications, too, that are not included in the collection below.
The RFCs are listed in numeric order.
"A specification for which significant implementation and successful operational experience has been obtained may be elevated to the Internet Standard level. An Internet Standard (which may simply be referred to as a Standard) is characterized by a high degree of technical maturity and by a generally held belief that the specified protocol or service provides significant benefit to the Internet community.
A specification that reaches the status of Standard is assigned a number in the STD Series while retaining its RFC number."
Definition of an Internet Standard – RFC 2026, 4.1.3

BOLO REVIEW:
We see a lot of potential for SharpStar, the site looks professional and easy to use. They also offer quick, fast and reliable payments and we have not had any issues so far.
Currently on SharpStar, you can find a variety of sports including soccer, tennis, golf, American football and the operator has said that more sports such as basketball and cricket are to come. Their “Hot Market” area helps users see what’s popular and its Guides and Tooltips across the site are useful for beginners. The site is available in English, Simplified Chinese and Traditional Chinese and offers a functional and good-looking mobile version.
Customers enjoy sports spread betting because they have more options. You can 'close a bet' (stop the bet before the end of an event) to lock in profits / limit losses. Also, you can 'flip a bet' (wager more to close the original bet and be left with an open bet on the opposite selection) if your opinion changes while the event is in-running.
HIGHLIGHTS:
• Min. stake size of CNY10
• Established in 2016
• Licensed and regulated in Curacao
• Potential to win a lot more vs fixed odds betting
• Uses your sports knowledge - the more right you are the more you win, but also the more incorrect you are, you can lose more
• Not a fixed price on win, lose or push. There is a high and low price for every market, which is called the ‘spread’
• Don’t have to wait until end of event to see result, can bet throughout the event and change your opinion
• 1000s of markets to choose from
• Can 'close' or 'flip a bet' before or during event to lock in profit or limit losses
• Excellent liquidity throughout their offerings
• Fast settlement of events & fast pay-outs
• Lots of tooltips, guides and useful information on their website to learn more about sports spread betting.
ABOUT SHARPSTAR
SharpStar is the first sports spread betting operator to launch in Asia. The idea behind their product was to combine the excitement of buying and selling options on financial markets and passion for sports.
Potential winnings and the sheer variety of markets are greater in spread betting than on fixed odds - the more you know, the more you can win. By using your sports knowledge, they claim that you can boost your profits in comparison to betting on fixed odds. In fixed odds betting, you are betting on particular outcome - it is a simple win, lose or push. Whereas in sports spread betting, it’s not fixed and is very fluid throughout an event.
There’s always a higher and lower figure, that’s what is called, ‘the spread’. SharpStar make predictions, then it’s up to you to decide if the final outcome will be higher or lower, more or less, faster or slower. If you think their price is too low, you would BUY (higher figure). If you think their quote is too high, you would SELL (lower figure).
Sports spread betting relies more than just the outcome, but your payout is dependant on how right you are or how wrong you are - and your stake size. It’s a very exciting opportunity to boost your profits if you have good sports knowledge.
EXAMPLES:
Fixed Odds Overs vs Spreads Total Goals market:
Selection: Everton vs Bournemouth
Final Score: 6-3
Make-up: 9 (6+3)
If you had staked 100 with SBO you would have won:
Stake 100 Overs 2.75 @ 2.06 = 100 x 1.06 = 106 PROFIT
But, if you had staked the same 100 with SharpStar you would have won:
Stake 100 Buy Price Total Goals @ 3.00 = 100 x (9 make-up - 3.00) = 600 PROFIT!!
Before you place a bet, you might want to try it. We offer Demo accounts pre-filled with virtual money.

How did the 'process over product' concept affect your site rebuild?
I was able to work to a plan before implementing the results. It was an outline that I creatd and my goal was to see that outline come to life, although difficult trying to bring the idea to life on the website.
What did you think about meditation before reading the chapter?
Before reading the chapter, I thought meditation was a form of relaxation, a way to calm the mind and therefore live a life full freedom and self expression.
What new things hav you learn't about meditaton?
- Meta attention is attention of attention, basically the ability to pay attention to attention itself.
- Meditation gets you to a state where your mind is relaxed and alert at the same time.
- When attention and meta-attention becomes strong, the mind becomes focused and stable.
- When the mind is highly relaxed and alert, qualities such as calmness, clarity and happiness emerge.
- Meditation is exercising the mind; training the mind so that it can gain more mental abilites.
- After a few months of meditation, there is significant improvements with a persons health.
- Creating good intentions is a form of meditation. Everytime an intention is created, it is subtly forming or reinforcing a mental habit.
Did any of the suggested Meditation techniques stand out?
In the case of a distraction, when I feel my mind begin to wonder, I need to first pay attention to that distraction by acknowledging the distraction. Experience it without judging or reacting and then let it go and slowly come back to a sense of mindfulness.
Any other musings
I enjoyed reading the analogies, especially the "Grandmother mind" intention who is the ideal candidate if you're feeling down because they are the type of idea that you need to boost your self esteem.

h1. Object#andand
h1. &x2192; ‘andand‘
h2. What
_Object#andand_ lets us write:

 @phone = Location.find(:first, …elided… ).andand.phone
And get a _guarded method invocation_ or _safe navigation method_. This snippet performs a @.find@ on the Location class, then sends @.phone@ to the result _if the result is not nil_. If the result is nil, then the expression returns nil without throwing a NoMethodError.
As Dejan Simic "put it":rors.org/2008/3/18/andand:
Why would you want to write this:

 entry.at(‘description’) && entry.at(‘description’).inner_text
when you can write this:

 entry.at(‘description’).andand.inner_text
Why indeed! As a bonus, install andand and you will also receive an enhanced Object#tap method, _at no extra charge_!
h2. Installing

sudo gem install andand

h2. The basics
h3. Object#andand
Ruby programmers are familiar with the two _guarded assignment_ operators @&&=@ and<EMAIL_ADDRESS>The typical use for them is when you have a variable that might be nil. For example:

 first_name &&= @first_name.trim @phone ||= ‘612-777-9311’
You are trimming the first name provided it isn’t nil, and you are assigning ‘612-777-9311’ to the phone if it is nil (or false, but that isn’t important right now). The other day we were discussing the guards and we agreed that we wished there was a _guarded method invocation_ operator. Here’s an example of when you would use it:

 @phone = Location.find(:first, …elided… )&&.phone
Meaning, search the location table for the first record matching some criteria, and if you find a location, get its phone. If you don’t, get nil. (Groovy provides this exact functionality, although Groovy uses @?.@ instead of @&&.@) However, @&&.@ won’t work because @&&.@ is not a real Ruby operator.
Object#andand let’s us write:

 @phone = Location.find(:first, …elided… ).andand.phone
And get the same effect as:

 @phone = ->(loc){ loc && loc.phone }.call(Location.find(:first, …elided… ))
Note that because you accept any method using Ruby’s method invocation syntax, you can accept methods with parameters and/or blocks:

 list_of_lists.detect { …elided… }.andand.inject(42) { …elided … }
Object#andand emphasizes syntactic regularity: the goal was to make an @&&.@ operation that worked like<EMAIL_ADDRESS>@&&=@ looks just like normal assignment, you can use any expression on the RHS, only the semantics are different. The andand method also works just like a normal method invocation, only the semantics are modified.
h3. Use andand to simplify your regular expression matching and extraction
Do you ever find yourself wanting to extract a single value from a string using a regular expression? For example, Ruby‘s Tempfile class creates paths to files that end in .pid.n (where pid is your process id and n is some number). Do you have a path that might be a tempfile and you want to obtain the base name?
Do you currently retrieve the MatchData object, check if it is nil, and get the first matching group if it isn‘t? How about:

 require ‘tempfile’ path = Tempfile.new(‘foo.bar’).path
=> "/var/folders/UZ/UZyZsbVPEWqC7tTXrQBYGU+++TI/-Tmp-/foo.bar.1280.0"
path.match('/([^/]+)\.+\.[0-9]+$’).andand[1]
=> "foo.bar"

With @.andand[1]@, you extract the group in the regular expression safely: if the expression matches, you get the group. If the expression fails to match, you get nil. Which is what you want, isn‘t it? The contents of the group if the expression matches? Why should you need more than one line for something so simple?
h3. Enhanced Object#tap
Ruby 1.9 introduces "Object#tap":moonbase.rydia.net/mental/blog/programming/eavesdropping-on-expressions. This library implements Object#tap for Ruby 1.8 and enhances it. As in Ruby 1.9, you can call @.tap@ with a block:

blah.sort.grep( /foo/ ).tap { |xs| p xs }.map { |x| x.blah }

 But like its sibling @.andand@, you can now call @.tap@ with a method as well:

[1, 2, 3, 4, 5].tap.pop.map { |n| n * 2 } => [2, 4, 6, 8]

h3. Doctor, it hurts when I do that
_So don‘t do that!_
The popular use case for Object#tap is poor man‘s debugging:

blah.sort.grep( /foo/ ).tap { |xs| p xs }.map { |x| x.blah }

Perhaps you want to remove the tap, you can delete it:

blah.sort.grep( /foo/ ).map { |x| x.blah }

Or, you can change it to @.dont@:

blah.sort.grep( /foo/ ).dont { |xs| p xs }.map { |x| x.blah }

Like @.andand@ and @.tap@, @.dont@ works with arbitrary methods, not just blocks:

(1..10).to_a.reverse! => [10, 9, 8, 7, 6, 5, 4, 3, 2, 1] (1..10).to_a.dont.reverse! => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

h2. A little more background
"Object#andand & Object#me in Ruby":weblog.raganwald.com/2008/01/objectandand-objectme-in-ruby.html explains the original motivations, as well as providing links to similar implementations you may want to consider. A few people have pointed out that Object#andand is similar to Haskell‘s Maybe monad. "The Maybe Monad in Ruby":blog.pretheory.com/arch/2008/02/the_maybe_monad_in_ruby.php is a good introduction for Ruby programmers.
h2. That‘s cool, but…
No problem, I get that andand isn‘t exactly what you need. Have a look at the "Invocation Construction Kit":ick.rubyforge.org or "Ick." The Ick gem generalizes andand and tap: Ick provides four useful ways to block-structure your code, the methods let, returning, inside, and my. Ick also includes four quasi-monadic invocations, maybe, please, tee, and fork.
"Ick":ick.rubyforge.org provides abstractions for building your own invocations, so you can branch out and build some of your own abstractions with Ick‘s building blocks.

Programming is an intriguing sector as it gives us the superpower to regulate computer programs on the go. It can be used for ships, traffic control, robotics, self-driving vehicles, smartphone applications, websites, and many other things.
It was 1985, I was 21 and I owned a 1979 Alfasud 1.5 Super in Posillipo blue (I learned the colour very early on, along with the cost of body filler). Two engines, £1000 in parts and less than a year later I found myself back on the bus to work. There, my love affair with Alfas appeared to have ended.

Process over Product
This concept reminds me that we are here to learn and it is the journey that we should be paying attention too and not the destination. When the focus is too much on the product then corners can get cut and valuable learning moments can be lost. As well as causing high amounts of stress when things don't look perfect.
Meditation before Chapter 2
Meditation is a good thing to do but still vaguely mystical. I was aware that it would help me focus and have other benefits.
Unsure on how I should position myself.
Meditation after Chapter 2
Meditation is scientifically speaking 'Mental training practices'. We can think about it like exercise. Growth happens when we apply resistance just like for weight lifting.
Our default setting is 'Happiness'. When we can achieve calm and stillness then we can return to our default. Our mind can be thought of as a snow globe and only when the snow is settled can we be at peace. We should allow ourselves to be happy. It is not something that can be pursued.
The mind is very closely linked with the body. Studies have shown that people given meditation training have a much more effective immune system. A life of meditation also slows down decay of gray matter in the brain.
The correct posture for meditation is any posture that allows a person to be alert and relaxed. "Sit like a majestic mountain"
Standout Techniques
Have the eyes half closed or alternate open and closed eyes to minimize distractions and chance of falling asleep.
- Acknowledge
- Experience
- Let go
Do not react to stimulus for 5 breaths. This means that you have a choice on the reaction which you can do mindfully and it also means that you are less likely to act in haste at a later date.
Musings
I found it very interesting that some of the pain receptors in the brain light up when we feel pain and also when we imagine pain. It is only the signal from our own limbs that let us know that we are not actually in pain. If we have lost the limb then the signal can't be sent resulting in pain/itchiness in a phantom limb.

What is your carbon footprint? Exclusive calculator shows how green you really are
As part of the Daily Mirror's climate edition we are publishing a carbon footprint calculator - an easy way to find out how much of the global warming gas you are pumping into the atmosphere each year
by Richard Innes, https://www.mirror.co.uk/authors/richard-innes/The world is heating up at an alarming rate and the amount of carbon dioxide humans are releasing into the atmosphere is a key reason why.
Every time we hop into the car, eat beef that was farmed from deforested land or buy an item of clothing shipped from across the globe, we are adding to the billions of tonnes of Co2 dumped into the atmosphere each year.
For decades now the scientific community unanimously agreed that the amount of Co2 in the atmosphere - which currently far exceeds any previously recorded level - is trapping heat inside the Earth's atmosphere.
The results is an increasingly hot planet on which ice caps melt, sea levels rise and extreme weather events become more and more common.
To find out how much of a contribution you are making to the 364.1 million tonnes of Co2 the UK chugged into the atmosphere last year, you can have a go on our carbon footprint calculator.
It is being released today as part of The Daily Mirror's climate edition, which aims to highlight the huge environmental changes that are happening to our planet right now.
To read the full manifesto click here.
The calculator asks you a series of question which determine how much of the gas you're responsible for pumping into the atmosphere each year.
These include transport issues, such as how many short, medium and long haul flights you take a year, how often you hop on the train, and whether you own a car.

Even clothes shopping, newspaper buying and thermostat usage habits are called into question.
At the end of the thorough exam the calculator tells you exactly how much carbon you're dumping into the atmosphere each year - with the chance to share with your friends exactly how big an eco-champion or carbon culprit you really are.
