Trac Macros
Trac macros are plugins to extend the Trac engine with custom 'functions' written in Python. A macro inserts dynamic HTML data in any context supporting WikiFormatting.
Another kind of macros are WikiProcessors. They typically deal with alternate markup formats and representation of larger blocks of information (like source code highlighting).
Using Macros
Macro calls are enclosed in two square brackets. Like Python functions, macros can also have arguments, a comma separated list within parentheses.
Getting Detailed Help
The list of available macros and the full help can be obtained using the MacroList macro, as seen below.
A brief list can be obtained via [[MacroList(*)]] or [[?]].
Detailed help on a specific macro can be obtained by passing it as an argument to MacroList, e.g. [[MacroList(MacroList)]], or, more conveniently, by appending a question mark (?) to the macro's name, like in [[MacroList?]].
Example
A list of 3 most recently changed wiki pages starting with 'Trac':
| Wiki Markup | Display |
|---|---|
[[RecentChanges(Trac,3)]] |
01/20/11
|
[[RecentChanges?(Trac,3)]] |
|
[[?]] |
Embed an image in wiki-formatted text.
The first argument is the file … |
Available Macros
Note that the following list will only contain the macro documentation if you've not enabled -OO optimizations, or not set the PythonOptimize option for mod_python.
[[Image]]
Embed an image in wiki-formatted text.
The first argument is the file specification. The file specification may reference attachments in three ways:
- module:id:file, where module can be either wiki or ticket, to refer to the attachment named file of the specified wiki page or ticket.
- id:file: same as above, but id is either a ticket shorthand or a Wiki page name.
- file to refer to a local attachment named 'file'. This only works from within that wiki page or a ticket.
Also, the file specification may refer to repository files, using the source:file syntax (source:file@rev works also).
Files can also be accessed with a direct URLs; /file for a project-relative, //file for a server-relative, or http://server/file for absolute location of the file.
The remaining arguments are optional and allow configuring the attributes and style of the rendered <img> element:
- digits and unit are interpreted as the size (ex. 120, 25%) for the image
- right, left, center, top, bottom and middle are interpreted as the alignment for the image (alternatively, the first three can be specified using align=... and the last three using valign=...)
- link=some TracLinks... replaces the link to the image source by the one specified using a TracLinks. If no value is specified, the link is simply removed.
- nolink means without link to image source (deprecated, use link=)
- key=value style are interpreted as HTML attributes or CSS style
indications for the image. Valid keys are:
- align, valign, border, width, height, alt, title, longdesc, class, margin, margin-(left,right,top,bottom), id and usemap
- border, margin, and margin-* can only be a single number
- margin is superseded by center which uses auto margins
Examples:
[[Image(photo.jpg)]] # simplest [[Image(photo.jpg, 120px)]] # with image width size [[Image(photo.jpg, right)]] # aligned by keyword [[Image(photo.jpg, nolink)]] # without link to source [[Image(photo.jpg, align=right)]] # aligned by attribute
You can use image from other page, other ticket or other module.
[[Image(OtherPage:foo.bmp)]] # if current module is wiki [[Image(base/sub:bar.bmp)]] # from hierarchical wiki page [[Image(#3:baz.bmp)]] # if in a ticket, point to #3 [[Image(ticket:36:boo.jpg)]] [[Image(source:/images/bee.jpg)]] # straight from the repository! [[Image(htdocs:foo/bar.png)]] # image file in project htdocs dir.
Adapted from the Image.py macro created by Shun-ichi Goto <gotoh@…>
[[InterTrac]]
Provide a list of known InterTrac prefixes.
[[InterWiki]]
Provide a description list for the known InterWiki prefixes.
[[KnownMimeTypes]]
List all known mime-types which can be used as WikiProcessors.
Can be given an optional argument which is interpreted as mime-type filter.
[[MacroList]]
Display a list of all installed Wiki macros, including documentation if available.
Optionally, the name of a specific macro can be provided as an argument. In that case, only the documentation for that macro will be rendered.
Note that this macro will not be able to display the documentation of macros if the PythonOptimize option is enabled for mod_python!
[[PageOutline]]
Display a structural outline of the current wiki page, each item in the outline being a link to the corresponding heading.
This macro accepts four optional parameters:
- The first is a number or range that allows configuring the minimum and maximum level of headings that should be included in the outline. For example, specifying "1" here will result in only the top-level headings being included in the outline. Specifying "2-3" will make the outline include all headings of level 2 and 3, as a nested list. The default is to include all heading levels.
- The second parameter can be used to specify a custom title (the default is no title).
- The third parameter selects the style of the outline. This can be either inline or pullout (the latter being the default). The inline style renders the outline as normal part of the content, while pullout causes the outline to be rendered in a box that is by default floated to the right side of the other content.
- The fourth parameter specifies whether the outline is numbered or not. It can be either numbered or unnumbered (the former being the default). This parameter only has an effect in inline style.
[[RecentChanges]]
List all pages that have recently been modified, ordered by the time they were last modified.
This macro accepts two ordered arguments and a named argument. The named argument can be placed in any position within the argument list.
The first parameter is a prefix string: if provided, only pages with names that start with the prefix are included in the resulting list. If this parameter is omitted, all pages are included in the list.
The second parameter is the maximum number of pages to include in the list.
The group parameter determines how the list is presented:
- group=date
- The pages are presented in bulleted lists that are grouped by date (default).
- group=none
- The pages are presented in a single bulleted list.
Tip: if you only want to specify a maximum number of entries and don't want to filter by prefix, specify an empty first parameter, e.g. [[RecentChanges(,10,group=none)]].
[[RepositoryIndex]]
Display the list of available repositories.
Can be given the following named arguments:
- format
-
Select the rendering format:
- compact produces a comma-separated list of repository prefix names (default)
- list produces a description list of repository prefix names
- table produces a table view, similar to the one visible in the Browse View page
- glob
- Do a glob-style filtering on the repository names (defaults to '*')
- order
- Order repositories by the given column (one of "name", "date" or "author")
- desc
- When set to 1, order by descending order
(since 0.12)
[[TicketQuery]]
Wiki macro listing tickets that match certain criteria.
This macro accepts a comma-separated list of keyed parameters, in the form "key=value".
If the key is the name of a field, the value must use the syntax of a filter specifier as defined in TracQuery#QueryLanguage. Note that this is not the same as the simplified URL syntax used for query: links starting with a ? character. Commas (,) can be included in field values by escaping them with a backslash (\).
Groups of field constraints to be OR-ed together can be separated by a litteral or argument.
In addition to filters, several other named parameters can be used to control how the results are presented. All of them are optional.
The format parameter determines how the list of tickets is presented:
- list -- the default presentation is to list the ticket ID next to the summary, with each ticket on a separate line.
- compact -- the tickets are presented as a comma-separated list of ticket IDs.
- count -- only the count of matching tickets is displayed
- table -- a view similar to the custom query view (but without the controls)
- progress -- a view similar to the milestone progress bars
The max parameter can be used to limit the number of tickets shown (defaults to 0, i.e. no maximum).
The order parameter sets the field used for ordering tickets (defaults to id).
The desc parameter indicates whether the order of the tickets should be reversed (defaults to false).
The group parameter sets the field used for grouping tickets (defaults to not being set).
The groupdesc parameter indicates whether the natural display order of the groups should be reversed (defaults to false).
The verbose parameter can be set to a true value in order to get the description for the listed tickets. For table format only. deprecated in favor of the rows parameter
The rows parameter can be used to specify which field(s) should be viewed as a row, e.g. rows=description|summary
For compatibility with Trac 0.10, if there's a last positional parameter given to the macro, it will be used to specify the format. Also, using "&" as a field separator still works (except for order) but is deprecated.
[[TitleIndex]]
Insert an alphabetic list of all wiki pages into the output.
Accepts a prefix string as parameter: if provided, only pages with names that start with the prefix are included in the resulting list. If this parameter is omitted, all pages are listed. If the prefix is specified, a second argument of value hideprefix can be given as well, in order to remove that prefix from the output.
Alternate format and depth named parameters can be specified:
- format=compact: The pages are displayed as comma-separated links.
- format=group: The list of pages will be structured in groups according to common prefix. This format also supports a min=n argument, where n is the minimal number of pages for a group.
- format=hierarchy: The list of pages will be structured according to the page name path hierarchy. This format also supports a min=n argument, where higher n flatten the display hierarchy
- depth=n: limit the depth of the pages to list. If set to 0, only toplevel pages will be shown, if set to 1, only immediate children pages will be shown, etc. If not set, or set to -1, all pages in the hierarchy will be shown.
- include=page1:page*2: include only pages that match an item in the colon-separated list of pages. If the list is empty, or if no include argument is given, include all pages.
- exclude=page1:page*2: exclude pages that match an item in the colon- separated list of pages.
The include and exclude lists accept shell-style patterns.
[[TracAdminHelp]]
Display help for trac-admin commands.
Examples:
[[TracAdminHelp]] # all commands [[TracAdminHelp(wiki)]] # all wiki commands [[TracAdminHelp(wiki export)]] # the "wiki export" command [[TracAdminHelp(upgrade)]] # the upgrade command
[[TracGuideToc]]
Display a table of content for the Trac guide.
This macro shows a quick and dirty way to make a table-of-contents for the Help/Guide?. The table of contents will contain the Trac* and WikiFormatting pages, and can't be customized. Search for TocMacro? for a a more customizable table of contents.
[[TracIni]]
Produce documentation for the Trac configuration file.
Typically, this will be used in the TracIni page. Optional arguments are a configuration section filter, and a configuration option name filter: only the configuration options whose section and name start with the filters are output.
[[Workflow]]
Render a workflow graph.
This macro accepts a TracWorkflow configuration and renders the states and transitions as a directed graph. If no parameters are given, the current ticket workflow is rendered. In WikiProcessors mode the width and height arguments can be specified.
(Defaults: width = 800 and heigth = 600)
Examples:
[[Workflow()]] [[Workflow(go = here -> there; return = there -> here)]] {{{ #!Workflow width=700 height=700 leave = * -> * leave.operations = leave_status leave.default = 1 accept = new,assigned,accepted,reopened -> accepted accept.permissions = TICKET_MODIFY accept.operations = set_owner_to_self resolve = new,assigned,accepted,reopened -> closed resolve.permissions = TICKET_MODIFY resolve.operations = set_resolution reassign = new,assigned,accepted,reopened -> assigned reassign.permissions = TICKET_MODIFY reassign.operations = set_owner reopen = closed -> reopened reopen.permissions = TICKET_CREATE reopen.operations = del_resolution }}}
Macros from around the world
The Trac Hacks site provides a wide collection of macros and other Trac plugins contributed by the Trac community. If you're looking for new macros, or have written one that you'd like to share with the world, please don't hesitate to visit that site.
Developing Custom Macros
Macros, like Trac itself, are written in the Python programming language and are developed as part of TracPlugins.
For more information about developing macros, see the development resources on the main project site.
Here are 2 simple examples showing how to create a Macro with Trac 0.11.
Also, have a look at Timestamp.py for an example that shows the difference between old style and new style macros and at the macros/README which provides a little more insight about the transition.
Macro without arguments
To test the following code, you should saved it in a timestamp_sample.py file located in the TracEnvironment's plugins/ directory.
from datetime import datetime # Note: since Trac 0.11, datetime objects are used internally from genshi.builder import tag from trac.util.datefmt import format_datetime, utc from trac.wiki.macros import WikiMacroBase class TimeStampMacro(WikiMacroBase): """Inserts the current time (in seconds) into the wiki page.""" revision = "$Rev$" url = "$URL$" def expand_macro(self, formatter, name, text): t = datetime.now(utc) return tag.b(format_datetime(t, '%c'))
Macro with arguments
To test the following code, you should saved it in a helloworld_sample.py file located in the TracEnvironment's plugins/ directory.
from genshi.core import Markup from trac.wiki.macros import WikiMacroBase class HelloWorldMacro(WikiMacroBase): """Simple HelloWorld macro. Note that the name of the class is meaningful: - it must end with "Macro" - what comes before "Macro" ends up being the macro name The documentation of the class (i.e. what you're reading) will become the documentation of the macro, as shown by the !MacroList macro (usually used in the WikiMacros page). """ revision = "$Rev$" url = "$URL$" def expand_macro(self, formatter, name, text, args): """Return some output that will be displayed in the Wiki content. `name` is the actual name of the macro (no surprise, here it'll be `'HelloWorld'`), `text` is the text enclosed in parenthesis at the call of the macro. Note that if there are ''no'' parenthesis (like in, e.g. [[HelloWorld]]), then `text` is `None`. `args` are the arguments passed when HelloWorld is called using a `#!HelloWorld` code block. """ return 'Hello World, text = %s, args = %s' % \ (Markup.escape(text), Markup.escape(repr(args)))
Note that expand_macro optionally takes a 4th parameter args. When the macro is called as a WikiProcessor, it's also possible to pass key=value processor parameters. If given, those are stored in a dictionary and passed in this extra args parameter. On the contrary, when called as a macro, args is None. (since 0.12).
For example, when writing:
{{{#!HelloWorld style="polite" <Hello World!> }}} {{{#!HelloWorld <Hello World!> }}} [[HelloWorld(<Hello World!>)]]
One should get:
Hello World, text = <Hello World!> , args = {'style': u'polite'} Hello World, text = <Hello World!> , args = {} Hello World, text = <Hello World!> , args = None
Note that the return value of expand_macro is not HTML escaped. Depending on the expected result, you should escape it by yourself (using return Markup.escape(result)) or, if this is indeed HTML, wrap it in a Markup object (return Markup(result)) with Markup coming from Genshi, (from genshi.core import Markup).
You can also recursively use a wiki Formatter (from trac.wiki import Formatter) to process the text as wiki markup, for example by doing:
from genshi.core import Markup from trac.wiki.macros import WikiMacroBase from trac.wiki import Formatter import StringIO class HelloWorldMacro(WikiMacroBase): def expand_macro(self, formatter, name, text, args): text = "whatever '''wiki''' markup you want, even containing other macros" # Convert Wiki markup to HTML, new style out = StringIO.StringIO() Formatter(self.env, formatter.context).format(text, out) return Markup(out.getvalue())

The CSS margin properties are used to create space around elements, outside of any
defined borders.
With CSS, you have full control over the margins. There are properties for setting the
margin for each side of an element (top, right, bottom, and left).
Margin - Individual Sides
CSS has properties for specifying the margin for each side of an element:
- margin-top
- margin-right
- margin-bottom
- margin-left
p {
margin-top: 100px;
margin-bottom: 100px;
margin-right: 150px;
margin-left: 80px;
}
The auto Value
You can set the margin property to auto to horizontally center the element within its container. The element will then take up the specified width, and the remaining space will be split equally between the left and right margins.
div {
width: 300px;
margin: auto;
border: 1px solid red;
}
Margin Collapse
Top and bottom margins of elements are sometimes collapsed into a single margin that is equal to the largest of the two margins. This does not happen on left and right margins! Only top and bottom margins!
h1 {
margin: 0 0 50px 0;
}
h2 {
margin: 20px 0 0 0;
}

Using Phoenix with docker, Part 1: Introduction
This is part one of a three part series: Part 1 - Part 2 - Part 3
This part is an introduction to the project - consider skipping to part 2 if you do want some code
Contents
A colleague of mine will not shut up about this.
Working at a company using Ruby for day to day work, Elixir seems pretty appealing. And since I tried out Haskell some years ago it seems kind of familiar. Especially since I didn’t really grasp the advantage of function pipelines and data structures back then. Also, working with PHP was so convenient at the time. I do recommend checking out Haskell at least once in your life, even though it’s (visible) presence in modern web development is slim.
Waking up from that hellish nightmare of Magento-based shop systems, I found myself working with Ruby (and Rails) a lot. Ruby is nice enough, but like every nice language it has some major problems of its own, like a missing language specification. Rails on top of it does make rapid development a joy, but its conventions are debatable and I’d argue that for everything good it brought us, it kicked us in the groin somewhere else (Looking at you, Turbolinks).
Rails introduced a lot of structure to web projects (seeing that web frameworks in other languages adopt to the same and or similiar structure), but, as most people I work with tell me these days, “it’s time to move on”.
So - Elixir will make everything magically better, right?
Probably not.
Show me a new “advanced” technology everyone praises, I’ll show you at least one developer who is able to screw things up in your project with it.
A good measure of a new language - to me - therefore would be how strongly you have to stick to the idioms that the language provides to solve your problems. Granted, this requires reflection on one’s own side to determine which kind of problems are to be solved. But that is just me rambling on what programming actually is, besides writing the code.
Using Phoenix & Elixir
Introduce Elixir. Elixir runs on the Erlang VM called BEAM. Being almost as old as myself (the first version of it was released in 1986), it’s one of the pieces of software that have been around so long it’s practically optimized to a degree that no recently created project is able to attain.
The fans usually pull out the WhatsApp example here. On one hand this has to do with the Erlang VM being extremly well optimized and well maintained. On the other hand the network stack of FreeBSD is a beast by itself. I confess I never looked into it, but I hear the praise from over the hills.
Using Erlang is a good idea apparently and Elixir makes it easier, because it packages it all in a more Ruby-esque, more “friendly” syntax. We can relate and do the same thing we always do - building our applications. Can’t be that different from the JVM, can it now? We got used to jRuby. And I think that one gal in the basement is still using and maintaining her own fork of IronRuby. She does not come to Christmas parties anymore.
Except we cannot - since Elixirs concepts are vastly different from what Ruby can provide you with. And you should keep that in mind - especially when starting out. I highly recommend Dave Thomas’ book here to start learning Elixir.
But since we’re doing web development, let’s take a look at Phoenix - the “Rails of the Elixir” world. It promises to bring the joy Rails development (and the useful conventions that come with it) and eliminating some of the more inconvient Rails-isms.
Using docker
Before diving into preparing a demo project let me quickly express that I find deployment of Phoenix/Elixir somewhat inconvenient. With Rails, you just use Heroku. That can be hard on your budget though (or on your mental health, as the Asset pipeline made your slug size explode again). So you might go on and deploy on your own machines, deciding to hire a DevOps guy in the process and then silently weep how hard actual scalable deployment is and that it shouldn’t come as an afterthought.
At the time of writing, Elixir has less convenient options (from what I can tell), so containerization might be a solution to this problem. After all, this approach will shift responsibility for having the dependencies installed to you instead of relying on your administrator to do so.
Note: I am aware that Heroku supports Elixir these days. I have not tried it yet, but my assumption is that not everyone chooses the expensive and convenient lock-in that Heroku provides.
So, I think it would be reasonable to try out some containers for the time being.
Project Kitteh
So, let us prepare something cat related to containerize and deploy somewhere.
Note: If you have not worked with Phoenix before, there are some excellent tutorials, as well as documentation. Naming can be a bit confusing, but when you’re used to the gem names in the Ruby ecosystem, my best bet is that you can get used to it.
Let’s do it:
mix phonix.new kitteh && cd kitteh
The project will do the following:
- Let the user upload a picture of a cat
- Present the user with a short, descriptive URL that they can share and that stays fixed forever™
- Provide modifiers to the url to scale the image (
Tiny
,Large
,Monstrous
), being scaled to a specific width
So, in practise, this should look as follows:
- User comes to url, uploads an image and get’s redirected to
/CuteDomesticSavannahKitty
- User can now use
/TinyCuteDomesticSavannahKitty
,/LargeCuteDomesticSavannahKitty
and/MonstrousCuteDomesticSavannahKitty
to get the resized versions as well.
Please note that I am intentionally - and shamelessly - stealing the URL naming strategy from gfycat.
The project should work as a tech demo to provide and explain the following components:
- the user frontend (web application)
- data storage for images and their properties
- serving images in a somewhat efficient way
- a queue solution with job workers (maybe …?)
The project can be grabbed from its repository if you are interested.
Long story short: We’re (probably) going to use these containers:
- PostgreSQL for database (one for postgres, one for persitant storage)
- Web Container running our Phoenix application
- nginx for serving static assets and uploaded images
Continuing
In the next part, we’ll look into the application stack and discuss Phoenix a bit more in depth. If you are more impatient, consider skipping directly to part 3 to see how the Dockerfile
s of our components look like and what the docker compose
process will be. Or if it even works.

All the classes that are going to use XLayout and all the containers inside of it
should have this annotation.
When using on a container, you need to set it's layout to null, and also remember
to set it's
name, because by default it's value = "",
this should be done to avoid "conflict" between the class container and this container,
unless you've changed the class container's name.
Note: The names are

Reflections
December 14, 2014
I value close relationships in my life. I feel that it's important to have close friends that you can rely on in life. I feel having a few close relationships are much better than having a lot of friends that are not as close. By having close relationships, you can trust them and you know they'll always be there for you when you need a hand or support in times of need.
When I take a look at the values in my life, I feel joy, excitement, and gratitude.
I think recognizing your feeling are important to controlling your feelings. Knowing your feelings of stereotype threat will help to mediate it. If I'm feeling down during at my time at DBC, I could talk to my close friends to get a another perspective of the situation. I know my close friends usually try to cheer me up. I could also take a break and maybe try to enjoy nature, like a walk, to help calm myself down and reset state of mind. I could say the accomplishments I've already acheived to make it known to myself. I've also heard it's helpful to say 3 positive things in your life you're glad to have each day to help you from feeling down.


The ff-push allows an end user to add a values to an end of an array by clicking the element.

FlxSprite
API Editimport flixel.FlxSprite;
FlxSprites are the core building blocks of all Flixel games. They offer a friendly API to add animation, movement and features for the needs of most games.
It is pretty common place to extend FlxSprite
for your own game's needs; for example a SpaceShip
class may extend FlxSprite
but could have additional variables for the game like shieldStrength
or shieldPower
. When you extend FlxSprite
it is important to remember to use super.update()
if you override the update
method, as you would do for any other FlxBasic
.
loadGraphic()
This method is the easiest way to use a single image for your FlxSprite. Using the OpenFL asset system defined in the project xml file you simply have to define a path to your image and the compiler will do the rest.
var player = new FlxSprite();
player.loadGraphic("assets/player.png");
add(player);
makeGraphic()
This method is a handy way to make a simple color fill to quickly test a feature or have the basic shape.
var whiteSquare = new FlxSprite();
whiteSquare.makeGraphic(200, 200, FlxColor.WHITE);
add(whiteSquare);
Properties
####Position: x, y
whiteSquare.x = 100;
whiteSquare.y = 300;
####Size: width, height
Automatically set in loadGraphic()
or makeGraphic()
, changing this will only affect the hitbox of this sprite, use scale
to change the graphic's size.
// get
var getWidth = whiteSquare.width;
// set
whiteSquare.width = 100;
whiteSquare.height = 100;
####Scale
(FlxPoint)
Change the size of your sprite's graphic. NOTE: The hitbox is not automatically adjusted, use updateHitbox()
for that (or setGraphicSize()
).
// twice as big
whiteSquare.scale.set(2, 2);
// 50%
whiteSquare.scale.set(0.5, 0.5);
####Offset (FlxPoint) Controls the position of the sprite's hitbox. Likely needs to be adjusted after changing a sprite's width, height or scale.
whiteSquare.offset.set(50, 50);
####Origin (FlxPoint) Rotation axis. Default: center.
WARNING: If you change this, the visuals and the collisions will likely be pretty out-of-sync if you do any rotation.
// rotate from top-left corner instead of center
whiteSquare.origin.set(0, 0);
kill()
This method is useful for when you want to hide a sprite from the stage but keep it available to reuse later. For example you may want to respawn an enemy the player has killed.
destroy()
This method is destructive to the sprite and should be used when you want to make sure that the sprite will be cleared from memory. It is commonly used inside a FlxState's overriden destroy method.
Animation
Flixel supports spritesheet animation.
player.loadGraphic("assets/player.png", true, 32, 36);
player.animation.add("walk", [0, 1, 0, 2], 5, true);
player.animation.play("walk");

Hi, My name is Raaj. I am a Senior Product Manager at Amazon and I drive CX improvements for our retail home improvement category. My background is in software development but I've been slightly out of touch with programming. Passion for coding got me to this boot camp and I look forward to learning more.
Outside of work, I like to play cricket and I enjoy going on road trips. I have driven all along the west coast in the US from Seattle to San Diego.

Why build a Progressive Web App?
Building a high-quality Progressive Web App has incredible benefits, making it easy to delight your users, grow engagement and increase conversions.Fast
53% of users will abandon a site if it takes longer than 3 seconds to load! And once loaded, users expect them to be fast—no janky scrolling or slow-to-respond interfaces.
Reliable
When launched from the user’s home screen, service workers enable a Progressive Web App to load instantly, regardless of the network state.
A service worker, written in JavaScript, is like a client-side proxy and puts you in control of the cache and how to respond to resource requests. By pre-caching key resources you can eliminate the dependence on the network, ensuring an instant and reliable experience for your users.
Engaging
Progressive Web Apps are installable and live on the user's home screen, without the need for an app store. They offer an immersive full screen experience with help from a web app manifest file and can even re-engage users with web push notifications. The Web App Manifest allows you to control how your app appears and how it's launched. You can specify home screen icons, the page to load when the app is launched, screen orientation, and even whether or not to show the browser chrome.
Lighthouse
Lighthouse, an open-source, automated tool for improving the quality of your Progressive Web Apps, eliminates much of the manual testing that was previously required. You can even use Lighthouse in continuous integration systems to catch regressions.

RECODE(1) FSF RECODE(1) NAME recode - converts files between character sets SYNOPSIS recode [OPTION]... [ [CHARSET] | REQUEST [FILE]... ] DESCRIPTION Free `recode' converts files between various character sets and surfaces. If a long option shows an argument as mandatory, then it is mandatory for the equivalent short option also. Similarly for optional arguments. Listings: -l, --list[=FORMAT] list one or all known charsets and aliases -k, --known=PAIRS restrict charsets according to known PAIRS list -h, --header[=[LN/]NAME] write table NAME on stdout using LN, then exit -F, --freeze-tables write out a C module holding all tables -T, --find-subsets report all charsets being subset of others -C, --copyright display Copyright and copying conditions --help display this help and exit --version output version information and exit Operation modes: -v, --verbose explain sequence of steps and report progress -q, --quiet, --silent inhibit messages about irreversible recodings -f, --force force recodings even when not reversible -t, --touch touch the recoded files after replacement -i, --sequence=files use intermediate files for sequencing passes --sequence=memory use memory buffers for sequencing passes -p, --sequence=pipe use pipe machinery for sequencing passes Fine tuning: -s, --strict use strict mappings, even loose characters -d, --diacritics convert only diacritics or alike for HTML/LaTeX -S, --source[=LN] limit recoding to strings and comments as for LN -c, --colons use colons instead of double quotes for diaeresis -g, --graphics approximate IBMPC rulers by ASCII graphics -x, --ignore=CHARSET ignore CHARSET while choosing a recoding path Option -l with no FORMAT nor CHARSET list available charsets and sur‐ faces. FORMAT is `decimal', `octal', `hexadecimal' or `full' (or one of `dohf'). Unless DEFAULT_CHARSET is set in environment, CHARSET defaults to the locale dependent encoding, determined by LC_ALL, LC_CTYPE, LANG. With -k, possible before charsets are listed for the given after CHARSET, both being tabular charsets, with PAIRS of the form `BEF1:AFT1,BEF2:AFT2,...' and BEFs and AFTs being codes are given as decimal numbers. LN is some language, it may be `c', `perl' or `po'; `c' is the default. REQUEST is SUBREQUEST[,SUBREQUEST]...; SUBREQUEST is ENCODING[..ENCOD‐ ING]... ENCODING is [CHARSET][/[SURFACE]]...; REQUEST often looks like BEFORE..AFTER, with BEFORE and AFTER being charsets. An omitted CHARSET implies the usual charset; an omitted [/SURFACE]... means the implied surfaces for CHARSET; a / with an empty surface name means no surfaces at all. See the manual. If none of -i and -p are given, presume -p if no FILE, else -i. Each FILE is recoded over itself, destroying the original. If no FILE is specified, then act as a filter and recode stdin to stdout.

A Short Survey of PProf Visualization Tools
March 17, 2017
Debugging CPU related issues can often lead to nuanced questions about trends. Does the heap usage spike or grow gradually? Where is this routine being called from and how often?
A picture is worth a thousand words
A picture provides useful context in a way that can otherwise be painful to interpret. By backing graph visualizations with pprof data useful CPU statistics can be contextualized over time.
What is PProf?
PProf is a cpu profiler that is part of the gperftools developed by Google for analyzing multi-threaded applications. The pprof package of golang’s standard library provides the data needed by the pprof tool via HTTP.
Since pprof data is served via HTTP, it is essential to run a webserver in your application. As a side-effect of simply importing pprof, the package will register its handlers with the running webserver so no further action is needed.
For a long-running application, this is an example of using pprof:
import (
"log"
"net/http"
_ "net/http/pprof"
)
func main(){
go func() {
log.Println(http.ListenAndServe("localhost:6060", nil))
}()
...
(taken from http://golang.org/pkg/net/http/pprof/)
Using pprof
http://blog.golang.org/profiling-go-programs
PProf comes with the ability to generate graphviz visualiztions of a program’s call graph. PProf bases the graph off of a 30 second sample from a running go application.
- Edges represent function calls and are labeled with number of samples with the given function call.
- Size of box corresponds to number of samples with function running.
- Each box has 2 labels: the percentage of time that the function was running and the percentage of time that it showed up as part of a stack trace.
Installation on Mac
$ brew install gperftools $ brew install graphviz $ pprof –web localhost:6060/debug
Go-Torch
http://github.com/uber/go-torch http://www.brendangregg.com/flamegraphs.html
Go-torch is a tool created by Uber to use Brendan Gregg’s scripts to generate flame graphs for go programs. Like PProf, the visualization is based off a 30 second sample from running the application.
- Stack frames are stacked on top of each other vertically, showing the stack depth.
- Frame width represent the percentage of time that a function showed up as part of a stack trace.
- If a function has several ancestors, it will show up several times. (On top of each distinct ancestor’s stack.)
- Colors are arbitrary and x-position is in alphabetical order.
Installation
requires the installation of go-torch tool, and flame graph scripts by brandangregg.
$ go get github.com/uber/go-torch
$ git clone git@github.com:brendangregg/FlameGraph.git
$ export PATH-$PATH:/path/to/FlameGraph
go-torch --file "torch.svg" --url http://localhost:6060
GOM
GOM is a real time curses-style command line tool with visualization of a running go application, written by Google developer Jaana Dogan.
- has visualization of running goroutines and machine threads over time.
- Updated in real time.
- In addition to visualization, GOM also provides text-based profiles of CPU and heap.
$ go get github.com/rakyll/gom/cmd/gom
as a side-effect of importing gom, gom will register extra handlers as well as the pprof ones.
import (
_ "github.com/rakyll/gom/http"
)
$ gom --target http://localhost:6060
Debug charts
http://github.com/mkevac/debugcharts
Debug charts is a tool by Marko Kevac that uses the plotly.js library to create a running web view of a running go application.
- Runs in browser.
- Has visualization of gc pauses, memory allocated and cpu usage.
- Updated in real time.
$ go get github.com/mkevac/debugcharts
as a side-effect of importing debugcharts, debugcharts will register extra handlers as well as the pprof ones.
Then direct your browser to localhost:6060/debug/charts}


The purpose of the imageNet package is to allow for users to produce clear and concise graphs of their networks. As a part of this package, the baseNet function produces a customizable visualizations of the standard network. This document is intended to show you how to best use the baseNet function.
To understand how to use the baseNet function, we’ll use the karate dataset as an example. This igraph dataset is a social network that maps relationships between members of a university karate club. The data is a part of the igraphdata package and is documented in greater detail in ?igraphdata::karate
library(igraphdata)
data("karate")
as_tbl_graph(karate)
#> # A tbl_graph: 34 nodes and 78 edges
#> #
#> # An undirected simple graph with 1 component
#> #
#> # Node Data: 34 x 4 (active)
#> Faction name label color
#> <dbl> <chr> <chr> <dbl>
#> 1 1 Mr Hi H 1
#> 2 1 Actor 2 2 1
#> 3 1 Actor 3 3 1
#> 4 1 Actor 4 4 1
#> 5 1 Actor 5 5 1
#> 6 1 Actor 6 6 1
#> # … with 28 more rows
#> #
#> # Edge Data: 78 x 3
#> from to weight
#> <int> <int> <dbl>
#> 1 1 2 4
#> 2 1 3 5
#> 3 1 4 3
#> # … with 75 more rows
As you can see above, the dataset contains 24 unique nodes and 78 edges. When we plot the igraph network using the standard plot() function, the following visulization is produced:
While this graph allows for us to gain a general understanding of our network, it could be improved significantly. One may find it beneficial to label the nodes using the complete name of each karate club member. Additionally, there is no key that makes it clear that the nodes are colored based on the “Faction” variable. Not only would it be good to know this information, but perhaps we would like to color the nodes based on some other variable. Furthermore, we might want to include a title that gives us a bit more information about the network. Now let’s see how the baseNet function can be applied to the karate data to allow us to gain a better understanding of the network.
k <- baseNet(karate, label = name, layout = "fr")
k
#> $data
#> # A tbl_graph: 34 nodes and 78 edges
#> #
#> # An undirected simple graph with 1 component
#> #
#> # Node Data: 34 x 8 (active)
#> Faction name label color betweenness closeness degree eigen
#> <dbl> <chr> <chr> <dbl> <dbl> <dbl> <dbl> <dbl>
#> 1 1 Mr Hi H 1 250. 0.00758 16 0.858
#> 2 1 Actor 2 2 1 33.8 0.00549 9 0.829
#> 3 1 Actor 3 3 1 36.6 0.00585 10 0.990
#> 4 1 Actor 4 4 1 1.33 0.00524 6 0.545
#> 5 1 Actor 5 5 1 0.5 0.00459 3 0.153
#> 6 1 Actor 6 6 1 15.5 0.00459 4 0.185
#> # … with 28 more rows
#> #
#> # Edge Data: 78 x 4
#> from to weight edge_weight
#> <int> <int> <dbl> <int>
#> 1 1 2 4 1
#> 2 1 3 5 1
#> 3 1 4 3 1
#> # … with 75 more rows
#>
#> $network
Note that the baseNet function produces a list, k, that contains both a tidygraph of the network (data) and a ggraph object of the network plot (network). Regardless, baseNet allows for the user to customize their network graph even further than see above. Let’s say one wishes to size the nodes based on their eigenvalue centricity. Then, the user should input the value eigen into the node_color argument of the baseNet function, which will produce the following plot:
Overall, the baseNet function allows users to modify the node size, node color, edge size, and edge color of their networks. They also have the option of specifying the label for the nodes, the color of the label color, and the layout of the network. For more information about the baseNet function and the ways in which it can be modified, please use ?imageNet::baseNet

It can also help Memory:
Sleep is incredibly important for memory consolidation. It helps because as you fall asleep, you tend to rehearse your information, and then in later stages, like stage 2 NREM sleep, you have slow wave sleep, which is also known to be an important stage for memorization. So if you have a big test, pulling an all nighter might not be as helpful as getting some sleep!

This plugin implements ANNA-PALM, which uses deep learning to reconstruct super-resolution views from sparse, rapidly acquired localization images and/or widefield images.
More details about ANNA-PALM can be found here: * **Publication**: Ouyang et. al, Deep learning massively accelerates super-resolution localization microscopy, Nature Biotechnology, 2018 * **GitHub**: https://github.com/imodpasteur/ANNA-PALM Here, we provide workflows to train and use ANNA-PALM to reconstruct super-resolution views from sparse localization and widefield images. We further provide example data for PALM experiments performed on microtubules. ## Installing the plugin and main features If you don't already have the plugin, you can install it from this **link.** When starting the ANNA-PALM plugin, you will see a **central launch pad** allowing to select the task to be performed: The **main features** are: * Training can be performed either on a provided remote plugin engine or a local plugin engine. * Trained model can be loaded and used for prediction or re-training of both simulations and experimental data. * Prediction can be performed once the model is trained.FOR IMJOY REVIEWERS: if you use the provided remote-engine, a pre-trained model is available at`imjoy/imjoy-paper/ANNA-PALM-MODEL`.
Here we describe how to load a pre-trained model that can be used either directly for prediction or for re-training.
## Trained model for microtubulins A pre-trained model for microtubulins is available **here**. 1. The actual model is contained in the folder `__model__`. 2. After downloading, you can load the trained model to the plugin engine (See FAQ for how to load data on the engine). ## Load model into ANNA-PALM plugin Pressing the button `Load trained model` will open a file-dialog where you can select a model that is stored on the plugin engine on which the plugin is running. This model is then available either for re-training or prediction.FOR IMJOY REVIEWERS: for immediating testing, you can use the provided remote engine 'imjoy.pasteur.cloud' with the 'GPU' tag. Further, training data for microtubules is already available at 'imjoy/imjoy-paper/ANNA-PALM-DATA'.
Here we describe how to select a plugin engine, a computational environment, and the training data to perform training.
## Training data * Training data consist of widefield and dense PALM/STORM images. The localization data must be provided using the csv format of ThunderSTORM. These data pairs have the same filename, except the extension. Training data will then be performed on sub-sampled PALM/STORM images. * Training and validation data are in separate folders 'train' and 'test'. Training data (the folder containing subfolder 'train' and 'test') has to be loaded onto the plugin engine, where the ANNA-PALM plugin is running. See FAQ for how to load data on the engine. Experimental test data is available **here**. The provided example data for the microtubules looks like this: ``` ├─ experimental_microtubules/ │ ├─ test/ │ │ ├─ Ctrl-lowDens_pos2.csv │ │ ├─ Ctrl-lowDens_pos2.png │ ├─ train/ │ │ ├─ Ctrl-lowDens_pos08.csv │ │ ├─ Ctrl-lowDens_pos08.png │ │ ├─ Ctrl-lowDens_pos10.csv │ │ ├─ Ctrl-lowDens_pos10.png │ │ ├─ ... ``` ## Where to perform training: plugin engine Training is performed on an ImJoy plugin engine, which can either run remotely or on your own local workstation. To install a local plugin engine, please follow **these instructions.** Once your ImJoy app is connected to one (or more) plugin engine(s), you can choose on which engine the CARE plugin should run. For this press on the icon next to the plugin name in the plugin menu. This will show a dropdown menu, where you can determine how and where the plugin is running. In the lower part of the dropdown menu you can then choose on which of the the available plugin engines the plugin should run. ## GPU or CPU computation Training can be performed on CPUs or GPUs. The latter is substantially faster. To switch between these computational modes, you can select the corresponding "tag". Currently supported are ## Monitoring training progress Once training data is provided, the training a dashboard will be shown that allows to inspect training progress. * In the upper part the dashboard shows the loss functions for the training and validation data. You can hoover over the curves to see the current value and what loss function it is. The slider allows you to scroll through the different training steps and inspect how the quality of the prediction changes. * In the lower part it shows the prediction results on a randomly selected image. 'A' stands for sparse (input image), 'B' for high-resolution image. The following images are shown - real_A: sparse input image - real_B: high-resolution target image - reco_B: reconstructed high-resolution image - squirrel_error_map: error map calculate with the squirrel approach If you want to **terminate the training** click on the icon next to the plugin name, select `Terminate` and then close the window with the red x. ## Trained model Once training is finished, the trained model can be used for prediction.

Campfire Coffee's unique and distinctive flavor comes from a special roasting process perfected over time. We roast small batches of carefully selected premium coffee beans over an open wood fire; using a patented method that infuses the coffee beans with smoke flavor. These small batches are hand ground while they are still warm and produce a deep coffee flavor like nothing you have tasted before. We choose the best highest quality wood for roasting our coffee, and our flavors consist of mesquite, hickory, apple, cherry, maple, pecan, and alder. Come try a sample at any one of our Seattle locations!
