Provides functions to compute and plot Coverage Probability Excursion (CoPE) sets for real valued functions on a 2-dimensional domain. CoPE sets are obtained from repeated noisy observations of the function on the entire domain. They are designed to bound the excursion set of the target function at a given level from above and below with a predefined probability. The target function can be a parameter in spatially-indexed linear regression. Support by NIH grant R01 CA157528 is gratefully acknowledged.

Rather than use the implementation provided in ebean-spring
you can write your
own Spring FactoryBean like the code below (or the spring boot EbeanFactoryBean example
Factory Bean (programmatic configuration of EbeanServer)).
Ebean is now aware of Spring boot runnable jar structure (for scanning the classpath). There is an example application showing:
This example does not show integration with Spring transactions (and instead uses Ebean's own transactions). Please
review the ebean-spring
project for that.
The ebean-spring provides a FactoryBean as well as integration with Spring transactions.
<@maven "io.ebean" "ebean-spring" "auto" "4" />
EbeanServerFactoryBean
is a spring FactoryBean that also holds a serverConfig.
It is expected to be used in conjunction with default-ebean-server.xml
which specifically
registers SpringAwareJdbcTransactionManager
as the external transaction manager on the ServerConfig.
SpringAwareJdbcTransactionManager
implements Ebean's ExternalTransactionManager API and provides the
integration into Spring transaction management.
SpringJdbcTransaction
extends Ebean's ExternalJdbcTransaction

is used by SpringAwareJdbcTransactionManager.

public class StoredIterator<E>
extends java.lang.Object
implements java.util.ListIterator<E>, java.lang.Cloneable
While in general this class conforms to the Iterator
interface,
it is important to note that all iterators for stored collections must be
explicitly closed with close()
. The static method close(java.util.Iterator)
allows calling close for all iterators without
harm to iterators that are not from stored collections, and also avoids
casting. If a stored iterator is not closed, unpredictable behavior
including process death may result.
This class implements the Iterator
interface for all stored
iterators. It also implements ListIterator
because some list
iterator methods apply to all stored iterators, for example, previous()
and hasPrevious()
. Other list iterator methods are always
supported for lists, but for other types of collections are only supported
under certain conditions. See nextIndex()
, previousIndex()
,
add(E)
and set(E)
for details.
In addition, this class provides the following methods for stored collection iterators only. Note that the use of these methods is not compatible with the standard Java collections interface.
| Modifier and Type | Method and Description |
|---|---|
void |
add(E value)
Inserts the specified element into the list or inserts a duplicate into
other types of collections (optional operation).
|
void |
close()
Closes this iterator.
|
static void |
close(java.util.Iterator<?> i)
Closes the given iterator using
close() if it is a StoredIterator . |
int |
count()
Returns the number of elements having the same key value as the key
value of the element last returned by next() or previous().
|
StoredCollection<E> |
getCollection()
Returns the collection associated with this iterator.
|
boolean |
hasNext()
Returns true if this iterator has more elements when traversing in the
forward direction.
|
boolean |
hasPrevious()
Returns true if this iterator has more elements when traversing in the
reverse direction.
|
boolean |
isReadModifyWrite()
Returns whether write-locks will be obtained when reading with this
cursor.
|
E |
next()
Returns the next element in the iteration.
|
int |
nextIndex()
Returns the index of the element that would be returned by a subsequent
call to next.
|
E |
previous()
Returns the next element in the iteration.
|
int |
previousIndex()
Returns the index of the element that would be returned by a subsequent
call to previous.
|
void |
remove()
Removes the last element that was returned by next or previous (optional
operation).
|
void |
set(E value)
Replaces the last element returned by next or previous with the
specified element (optional operation).
|

Changes whether write-locks will be obtained when reading with this
cursor.

[gecode-users] changing a Space's AFC decay factor
Kish Shen
kisshen at cisco.com
Thu Dec 5 22:05:07 CET 2013
Hi,
I am looking at the documentation for AFC in the class documentation for
Space (section low-level support for AFC), and I don't understand what
afc_set(double a) does:
The description say it 'Reset AFC to a', but I thought there is no
global AFC value, as each variable has its own AFC value?
[Also, I noticed a possibly incorrect link in the description for
afc_decay(double d):
the Set in 'Set AFC decay factor to d' is linked to Gecode:Set ]
Cheers,
Kish

The more frequently a feature is needed, the more valuable it is. And the more valuable a feature, the earlier it should be implemented.
On the other hand, the more frequently a feature is needed, the less UI gestures (clicks) it should require.
Therefore there should be a positive correlation between click count and iteration number for each feature. This could probably be a useful user experience metric.
If only it was possible to calculate this from automated tests and the backlog...

yamfp¶
The Youtube Audio Matcher Fingerprinting
command line tool yamfp
can be used to visualize the spectrogram and
fingerprints (peak pair hash constellation) of an audio file.
Usage¶
usage: yamfp [-h] [--erosion-iterations <int>] [-f <int>]
[--filter-connectivity {1,2}] [--filter-dilation <int>]
[--max-time-delta <float>] [--min-time-delta <float>] [-a <dB>]
[--spectrogram-backend {scipy,matplotlib}]
[--win-overlap-ratio <float>] [--win-size <int>]
[-c <channel> [<channel> ...]] [-p] [-F] [-t <title>]
[--start <seconds>] [--end <seconds>]
<path>
Visualize an audio file fingerprint by plotting its spectrogram, spectrogram
peaks, and/or fingerprint (peak pairs).
positional arguments:
<path> Path to audio file
optional arguments:
-h, --help show this help message and exit
-c <channel> [<channel> ...], --channels <channel> [<channel> ...]
Plot only the specified audio channels (beginning at
0) (default: None)
-p, --no-peaks Do not plot spectrogram peaks (default: False)
-F, --plot-fingerprints
Plot fingerprint constellations between peak pairs
instead of plotting spectrogram (default: False)
-t <title>, --title <title>
Set plot title; defaults to filename if omitted
(default: None)
--start <seconds> Audio segment end time in seconds (beginning of file
if omitted) (default: None)
--end <seconds> Audio segment end time in seconds (end of file if
omitted) (default: None)
fingerprint arguments:
--erosion-iterations <int>
Number of times to apply binary erosion for peak
finding (default: 1)
-f <int>, --fanout <int>
Number of adjacent peaks to consider for generating
hashes (default: 3)
--filter-connectivity {1,2}
Max filter neighborhood connectivity for peak finding
(default: 1)
--filter-dilation <int>
Max filter dilation (neighborhood size) for peak
finding (default: 10)
--max-time-delta <float>
Target zone max time offset difference for hashes
(default: 10)
--min-time-delta <float>
Target zone min time offset difference for hashes
(default: 1)
-a <dB>, --min-amplitude <dB>
Spectogram peak minimum amplitude in dB (default: 10)
--spectrogram-backend {scipy,matplotlib}
Library to use for computing spectrogram (default:
scipy)
--win-overlap-ratio <float>
Window overlap as a fraction of window size, in the
range [0, 1) (default: 0.5)
--win-size <int> Number of samples per FFT window (default: 4096)
Examples¶
By default, the yamfp
command generates a spectrogram for each channel of
the input file, with the peaks drawn as red dots:
yamfp file.mp3
To select the channels to plot, use the -c
/--channels
option followed
by a space-separated list of (zero-indexed) channels to plot. To plot only the
first channel:
yamfp file.mp3 -c 0
To select a specific segment of the audio file, use the --start
and/or
--end
options. This example plots the segment of the file from 30 seconds
to 40 seconds:
yamfp file.mp3 -c 0 --start 30 --end 40
To plot the spectrogram without the peaks, add the -p
/--no-peaks
switch:
yamfp file.mp3 -c 0 --start 30 --end 40 -p
To plot the hash constellation (fingerprint peak pairs) instead of the
spectrogram, use -F
/--plot-fingerprints
switch:
yamfp file.mp3 -c 0 --start 30 --end 40 -F
The parameters for computing the spectrogram, peak-finding, and peak pair
selection can be modified as well, per the fingerprint arguments section
of the usage help. These parameters are explained in
youtube_audio_matcher.audio.get_spectrogram()
and
youtube_audio_matcher.audio.find_peaks_2d()
.

FDStatusBarNotifierView 0.1.0 Reference
FDStatusBarNotifier is a UIView subclass that lets you display notifications using the space in which the status bar resides.
](http://github.com/frankdilo/FDStatusBarNotifierView/raw/master/Screenshot.png))
Installation
Copy File
To use it just drag and drop FDStatusBarNotifierView
.h
and FDStatusBarNotifierView
.m
in your project, import the .h
file in your view controller implementation and use the code shown in the example above.
Cocoapods
You can use CocoaPods to manage your dependencies and install FDStatusBarNotifierView.
Follow the instructions on the CocoaPods site to install the gem and add pod 'FDStatusBarNotifierView', :git => '
https://github.com/frankdilo/FDStatusBarNotifierView.git' to your Podfile.
Use
It’s as easy to use as UIAlertView
, here is an example:
// from a view controller
FDStatusBarNotifierView *notifierView = [[FDStatusBarNotifierView alloc] initWithMessage:@"Hi"];
notifierView.timeOnScreen = 3.0;
[notifierView showInWindow:self.view.window];
When you call showInWindow:
the status bar disappear and the notifier view takes its place with a smooth animation.
Manually hide
In some circumstances (e.g., informing the user of network activities), you may want to manually hide the component.
To do so just set the manuallyHide
property to YES
. Then hide calling the hide
method.
notifierView.manuallyHide = YES;
// do some stuff
[notifierView hide];
More
- If you set the
shouldHideOnTap
property toYES
when the user touch the message it will be hidden. - If the message you want to display doesn’t fit in the status bar it will be animated and scroll horizontally to display the full text.
Optional delegate methods
I’ve also created some handy self-explanatory delegate methods, if you need them.
- (void)willPresentNotifierView:(FDStatusBarNotifierView *)notifierView; // before animation and showing view
- (void)didPresentNotifierView:(FDStatusBarNotifierView *)notifierView; // after animation
- (void)willHideNotifierView:(FDStatusBarNotifierView *)notifierView; // before hiding animation
- (void)didHideNotifierView:(FDStatusBarNotifierView *)notifierView; // after animation
- (void)notifierViewTapped:(FDStatusBarNotifierView *)notifierView; // user tap the status bar message
Contribute
Feel free to help out by sending pull requests or by creating new issues.
Contributors
- ZachOrr: iPad support, hide on tap, better handling of device’s screen sizes.
- dbsGen: if the message to display doesn’t fit in the status bar, it will scroll horizontally.
- Luca Bernardi: CocoaPods support, manual hiding.
TO DO
- Add support for multiple orientations (currently only portrait is supported).
- Properly manage the animation queue, to avoid unexpected behavior when
showInWindow:
is called multiple times.

Sorry if this is already covered somewhere. What should the order of the inputs be in a definition such as
lemma nth_root_pow_left {x : ℝ} {m n : ℕ} (Hm : 0 < m) (Hx : 0 < x) : (nth_root x m) ^ (m * n) = x ^ n :=
? I'm writing a little library about n'th roots and I've realised that I'm just putting the reals and nats and positivity facts in random and inconsistent orders.
x
before m
, so x
before m

WXT - project
|
The WXT-project is a project at Østfold College. The purpose is to produce tools for maintenance of websites and printed documents. The target is material for education, but the WXT should be applicable to a wide range of small and medium sized web projects. The tasks that can be achieved with WXT are:
|
WXT is basically built on the rather naive observation that: "If all material on the web is wellformed XML, all material on the web is available with an URI and a XPATH". Unfortunately the world is not wellformed, and WXT attempts to compencate for that by allowing import and management of other material than XML. At the moment WXT can, in addition to XML, handle text, HTML(5) and databases(mySQL). WXT is free and is distributed "as is". |

We believe in guiding all students toward achieving their individual potential and attaining success.
We believe in offering a diverse and challenging curriculum that prepares our students for future endeavors.
We believe that success is obtained through personal responsibility, initiative, high expectations, honest effort, and a dedication to individual goals.
We believe in providing an environment that is built on respecting self and others and is conducive to learning and building self-esteem.
We believe that parents are essential participants in the learning process and should continue being an integral part of their children’s educational experience in our school.
The Saint Thomas School makes every effort to provide a learning environment conducive to the development of the intellectual, physical and social area of every student, in order for each student to reach his or her optimal academic and social potential. Leadership, self-discipline, cooperation, ethical behavior, and respect towards others, are equally important to the school. This is to be accomplished through a well-rounded program that integrates core values in citizenship, responsibility and integrity.
In all aspects of the academic program, the student is the center of our efforts. The goal is to see that our students experience personal growth while they prepare academically to face the many challenges that they will meet throughout their lives. Our main goal is to assist the students to develop critical thinking and, analytical skills, teaching them to use these skills in a rational and effective way.
Our program of studies emphasizes appreciation for aesthetics and cultural values. Music, art, foreign languages, and technology are integrated into the program of studies. These are designed to provide a wider view of the world around them, and to prepare them to make wise and appropriate decisions in life.
The basic academic program includes instruction in English for each of the following areas: Language Arts, Mathematics, Science, Social Studies, Health, Computers and Physical Education. In addition, the program includes instruction in Spanish for the courses required by the Dominican Ministry of Education. Strong efforts are made to integrate various aspects of the program of studies. Basic objectives for eighth grade through level twelve are identified and consolidated for all areas of the curriculum. The Common Core Standards provide the foundation, or core, of the program. Student progress is monitored continuously, on the basis of formative assessments. Strong emphasis is placed on developing Critical Thinking skills by having students research, analyze, and come up with their own conclusion supported with reliable sources and references.
The School is committed to provide a balanced program of instruction in English that meets the highest standards of an American-based curriculum, commensurate with the abilities, interests, and educational needs of our student body. In addition, the program provides instruction in Spanish that prepares students to further their education whether they seek to pursue studies in a U.S. school, college or university or a local university. The program meets the requirements of the Dominican Ministry of Education, allowing students to experience involvement in their cultural and historical context; this provides awareness and tolerance of diversity.
Welcome to Saint Thomas School, home of the Falcons! We are committed to a strong and comprehensive educational program, a nurturing and learning environment that enhances self esteem, provides role models, allows for each child’s potential, and accentuates individual respect.
Saint Thomas School’s rigorous curriculum is the foundation that will prepare all of our students for future endeavors.
As you will see, this website will provide you with important information that is set up logically and is user friendly. This website will facilitate even greater access to information and improved communications between home and school.
As you navigate through our site, I hope you get a feel for what makes Saint Thomas School not only a school of excellence, but also a family friendly environment. Please visit us on campus and see what makes this school educational experience such a unique opportunity. Again, welcome to Saint Thomas School. I look forward to meeting you and your child(ren).
Sincerely,
Dafne Urena, M.Ed.
Academic Director
The Saint Thomas School's Counseling Department, among other things, offers college and career guidance to students during their high school years. The department advises students and parents regarding high school programs, and prepares them for college application and admission. Up to date, our students have been admitted and have enrolled into several prestigious colleges and universities abroad.

title=How to get your twitter results visible on your site date=2008-11-08 type=post tags=blog status=published ~~~~~~ Matt Raible added Twitter updates to his blog. (Exhibit A). I decided to the do same. First, you'll need the twitter.js JavaScript. This can be found here. I would download this one. Install that script onto your site, ie:

Finally, add the code on your page to configure and use it.
This looks something like this:

This javascript tells the script to load the latest 3 updates (count
) in the HTML element (in my case, a regular old DIV element) having ID "twitter_box". It tells the script that, if there's already something inside that DIV element, it should merely append to it, not overwrite it.
The prefix
attribute let's you specify what code you want to have inserted above and beyond the link and status text. This javascript has its own little macro substitution routine! You can dynamically insert variables like the url of your tweet ("tweet being what a single status update on twitter is called.) into the prefix string and it'll get replaced at runtime.
Finally, make sure to insert the HTML element where you want the Twitter updates to display somewhere on your page.
The html is easy, and could be as simple as

 My Twitter.com.

Thanks, Matt!

Eco Lab is an object oriented simulation environment that
implements an experiment oriented metaphor. It provides a series of
instruments that can be coupled together with the user's model
(written in C++) at runtime in order to visualise the model, as well
as support for for distributing agents over an arbitrary topology
graph, partitioned over multiple processors and checkpoint/restart
support.
Eco Lab was originally developed to simulate a particular
model (the
Eco Lab model) of an abstract
ecology[
7]. However, several other quite different
models have been implemented using the software, demonstrating its
general purpose nature.


Object
Represents a collection of connections to various servers. It provides an interface for organizing the connections (group), as well as a way to scope commands to a subset of all connections (with). You can also provide a default gateway connection that servers should use when connecting (via). It exposes an interface similar to Net::SSH::Connection::Session for opening SSH channels and executing commands, allowing for these operations to be done in parallel across multiple connections.
Net::SSH::Multi.start do |session| # access servers via a gateway session.via 'gateway', 'gateway-user' # define the servers we want to use session.use 'user1@host1' session.use 'user2@host2' # define servers in groups for more granular access session.group :app do session.use 'user@app1' session.use 'user@app2' end # execute commands on all servers session.exec "uptime" # execute commands on a subset of servers session.with(:app).exec "hostname" # run the aggregated event loop session.loop end
Note that connections are established lazily, as soon as they are needed. You can force the connections to be opened immediately, though, using the connect! method.
Sometimes you may be dealing with a large number of servers, and if you try to have connections open to all of them simultaneously you’ll run into open file handle limitations and such. If this happens to you, you can set the concurrent_connections property of the session. Net::SSH::Multi will then ensure that no more than this number of connections are ever open simultaneously.
Net::SSH::Multi.start(:concurrent_connections => 5) do |session| # ... end
Opening channels and executing commands will still work exactly as before, but Net::SSH::Multi will transparently close finished connections and open pending ones.
By default, Net::SSH::Multi will raise an exception if a connection error occurs when connecting to a server. This will typically bubble up and abort the entire connection process. Sometimes, however, you might wish to ignore connection errors, for instance when starting a daemon on a large number of boxes and you know that some of the boxes are going to be unavailable.
To do this, simply set the on_error property of the session to :ignore (or to :warn, if you want a warning message when a connection attempt fails):
Net::SSH::Multi.start(:on_error => :ignore) do |session| # ... end
The default is :fail, which causes the exception to bubble up. Additionally, you can specify a Proc object as the value for on_error, which will be invoked with the server in question if the connection attempt fails. You can force the connection attempt to retry by throwing the :go symbol, with :retry as the payload, or force the exception to be reraised by throwing :go with :raise as the payload:
handler = Proc.new do |server| server[:connection_attempts] ||= 0 if server[:connection_attempts] < 3 server[:connection_attempts] += 1 throw :go, :retry else throw :go, :raise end end Net::SSH::Multi.start(:on_error => handler) do |session| # ... end
Any other thrown value (or no thrown value at all) will result in the failure being ignored.
Sometimes you might be dealing with an environment where you don’t know the names or addresses of the servers until runtime. You can certainly dynamically build server names and pass them to use, but if the operation to determine the server names is expensive, you might want to defer it until the server is actually needed (especially if the logic of your program is such that you might not even need to connect to that server every time the program runs).
You can do this by passing a block to use:
session.use do |opt| lookup_ip_address_of_remote_host end
See use for more information about this usage.
The number of allowed concurrent connections. No more than this number of sessions will be open at any given time.
The default Net::SSH::Gateway instance to use to connect to the servers. If nil, no default gateway will be used.
The hash of group definitions, mapping each group name to a corresponding Net::SSH::Multi::ServerList.
Creates a new Net::SSH::Multi::Session instance. Initially, it contains no server definitions, no group definitions, and no default gateway.
You can set the concurrent_connections property in the options. Setting it to nil (the default) will cause Net::SSH::Multi to ignore any concurrent connection limit and allow all defined sessions to be open simultaneously. Setting it to an integer will cause Net::SSH::Multi to allow no more than that number of concurrently open sessions, opening subsequent sessions only when other sessions finish and close.
Net::SSH::Multi.start(:concurrent_connections => 10) do |session| session.use ... end
# File lib/net/ssh/multi/session.rb, line 171 def initialize(options={}) @server_list = ServerList.new @groups = Hash.new { |h,k| h[k] = ServerList.new } @gateway = nil @open_groups = [] @connect_threads = [] @on_error = :fail @default_user = ENV['USER'] || ENV['USERNAME'] || "unknown" @open_connections = 0 @pending_sessions = [] @session_mutex = Mutex.new options.each { |opt, value| send("#{opt}=", value) } end
Closes the multi-session by shutting down all open server sessions, and the default gateway (if one was specified using via). Note that other gateway connections (e.g., those passed to use directly) will not be closed by this method, and must be managed externally.
# File lib/net/ssh/multi/session.rb, line 402 def close server_list.each { |server| server.close_channels } loop(0) { busy?(true) } server_list.each { |server| server.close } default_gateway.shutdown! if default_gateway end
At its simplest, this associates a named group with a server definition. It can be used in either of two ways:
First, you can use it to associate a group (or array of groups) with a server definition (or array of server definitions). The server definitions must already exist in the server_list array (typically by calling use):
server1 = session.use('host1', 'user1') server2 = session.use('host2', 'user2') session.group :app => server1, :web => server2 session.group :staging => [server1, server2] session.group %w(xen linux) => server2 session.group %w(rackspace backup) => [server1, server2]
Secondly, instead of a mapping of groups to servers, you can just provide a list of group names, and then a block. Inside the block, any calls to use will automatically associate the new server definition with those groups. You can nest group calls, too, which will aggregate the group definitions.
session.group :rackspace, :backup do session.use 'host1', 'user1' session.group :xen do session.use 'host2', 'user2' end end
# File lib/net/ssh/multi/session.rb, line 213 def group(*args) mapping = args.last.is_a?(Hash) ? args.pop : {} if mapping.any? && block_given? raise ArgumentError, "must provide group mapping OR block, not both" elsif block_given? begin saved_groups = open_groups.dup open_groups.concat(args.map { |a| a.to_sym }).uniq! yield self ensure open_groups.replace(saved_groups) end else mapping.each do |key, value| (open_groups + Array(key)).uniq.each do |grp| groups[grp.to_sym].concat(Array(value)) end end end end
Run the aggregated event loop for all open server sessions, until the given block returns false. If no block is given, the loop will run for as long as busy? returns true (in other words, for as long as there are any (non-invisible) channels open).
# File lib/net/ssh/multi/session.rb, line 415 def loop(wait=nil, &block) running = block || Proc.new { |c| busy? } loop_forever { break unless process(wait, &running) } end
Works as with, but for specific servers rather than groups. It will return a new subsession (Net::SSH::Multi::Subsession) consisting of the given servers. (Note that it requires that the servers in question have been created via calls to use on this session object, or things will not work quite right.) If a block is given, the new subsession will also be yielded to the block.
srv1 = session.use('host1', 'user') srv2 = session.use('host2', 'user') # ... session.on(srv1, srv2).exec('hostname')
# File lib/net/ssh/multi/session.rb, line 392 def on(*servers) subsession = Subsession.new(self, servers) yield subsession if block_given? subsession end
Run a single iteration of the aggregated event loop for all open server sessions. The wait parameter indicates how long to wait for an event to appear on any of the different sessions; nil (the default) means “wait forever”. If the block is given, then it will be used to determine whether process returns true (the block did not return false), or false (the block returned false).
# File lib/net/ssh/multi/session.rb, line 426 def process(wait=nil, &block) realize_pending_connections! wait = @connect_threads.any? ? 0 : wait return false unless preprocess(&block) readers = server_list.map { |s| s.readers }.flatten writers = server_list.map { |s| s.writers }.flatten readers, writers, = IO.select(readers, writers, nil, wait) if readers return postprocess(readers, writers) else return true end end
Essentially an alias for servers_for without any arguments. This is used primarily to satistfy the expectations of the Net::SSH::Multi::SessionActions module.
# File lib/net/ssh/multi/session.rb, line 293 def servers servers_for end
Returns the set of servers that match the given criteria. It can be used in any (or all) of three ways.
First, you can omit any arguments. In this case, the full list of servers will be returned.
all = session.servers_for
Second, you can simply specify a list of group names. All servers in all named groups will be returned. If a server belongs to multiple matching groups, then it will appear only once in the list (the resulting list will contain only unique servers).
servers = session.servers_for(:app, :db)
Last, you can specify a hash with group names as keys, and property constraints as the values. These property constraints are either “only” constraints (which restrict the set of servers to “only” those that match the given properties) or “except” constraints (which restrict the set of servers to those whose properties do not match). Properties are described when the server is defined (via the :properties key):
session.group :db do session.use 'dbmain', 'user', :properties => { :primary => true } session.use 'dbslave', 'user2' session.use 'dbslve2', 'user2' end # return ONLY on the servers in the :db group which have the :primary # property set to true. primary = session.servers_for(:db => { :only => { :primary => true } })
You can, naturally, combine these methods:
# all servers in :app and :web, and all servers in :db with the # :primary property set to true servers = session.servers_for(:app, :web, :db => { :only => { :primary => true } })
# File lib/net/ssh/multi/session.rb, line 334 def servers_for(*criteria) if criteria.empty? server_list.flatten else # normalize the criteria list, so that every entry is a key to a # criteria hash (possibly empty). criteria = criteria.inject({}) do |hash, entry| case entry when Hash then hash.merge(entry) else hash.merge(entry => {}) end end list = criteria.inject([]) do |aggregator, (group, properties)| raise ArgumentError, "the value for any group must be a Hash, but got a #{properties.class} for #{group.inspect}" unless properties.is_a?(Hash) bad_keys = properties.keys - [:only, :except] raise ArgumentError, "unknown constraint(s) #{bad_keys.inspect} for #{group.inspect}" unless bad_keys.empty? servers = groups[group].select do |server| (properties[:only] || {}).all? { |prop, value| server[prop] == value } && !(properties[:except] || {}).any? { |prop, value| server[prop] == value } end aggregator.concat(servers) end list.uniq end end
Defines a new server definition, to be managed by this session. The server is at the given host, and will be connected to as the given user. The other options are passed as-is to the Net::SSH session constructor.
If a default gateway has been specified previously (with via) it will be passed to the new server definition. You can override this by passing a different Net::SSH::Gateway instance (or nil) with the :via key in the options.
session.use 'host' session.use 'user@host2', :via => nil session.use 'host3', :user => "user3", :via => Net::SSH::Gateway.new('gateway.host', 'user')
If only a single host is given, the new server instance is returned. You can give multiple hosts at a time, though, in which case an array of server instances will be returned.
server1, server2 = session.use "host1", "host2"
If given a block, this will save the block as a Net::SSH::Multi::DynamicServer definition, to be evaluated lazily the first time the server is needed. The block will recive any options hash given to use, and should return nil (if no servers are to be added), a String or an array of Strings (to be interpreted as a connection specification), or a Server or an array of Servers.
# File lib/net/ssh/multi/session.rb, line 274 def use(*hosts, &block) options = hosts.last.is_a?(Hash) ? hosts.pop : {} options = { :via => default_gateway }.merge(options) results = hosts.map do |host| server_list.add(Server.new(self, host, options)) end if block results << server_list.add(DynamicServer.new(self, options, block)) end group [] => results results.length > 1 ? results : results.first end
Sets up a default gateway to use when establishing connections to servers. Note that any servers defined prior to this invocation will not use the default gateway; it only affects servers defined subsequently.
session.via 'gateway.host', 'user'
You may override the default gateway on a per-server basis by passing the :via key to the use method; see use for details.
# File lib/net/ssh/multi/session.rb, line 243 def via(host, user, options={}) @default_gateway = Net::SSH::Gateway.new(host, user, options) self end
Returns a new Net::SSH::Multi::Subsession instance consisting of the servers that meet the given criteria. If a block is given, the subsession will be yielded to it. See servers_for for a discussion of how these criteria are interpreted.
session.with(:app).exec('hostname') session.with(:app, :db => { :primary => true }) do |s| s.exec 'date' s.exec 'uptime' end
# File lib/net/ssh/multi/session.rb, line 375 def with(*groups) subsession = Subsession.new(self, servers_for(*groups)) yield subsession if block_given? subsession end

Snort aprox. 30mg of Methylone. Initial alert felt within 3 minutes, building within 15 to a distinct though quite mild warm glow. Substance seems very easy on the nose, no burn to speak of, and post nasal drip while not enjoyable by no means intolerable. I've yet to ingest orally but assume that this ammount by that route would be essentially inactive. Otherwise very reminiscent of a similar ammount of MDMA by the same route, seems less pusy, gentler though perhaps not euphoric--not necesserialy a bad thing as I've long ceased to enjoy E.
1 h 15 min later I decided to snort an equivalent ammount, since the effects of the first line seem to retreating. While methylone is undoubtedly potentiated by this route, I donít think itís a spectacular potentiation as in the case of 2CB and 2CT7--which are both considerable enhanced when taken in this way. It may be that like MDMA its active intranasaly, but in such a way that it never reveals its full glory. MDMA when snorted in my experience never seems to have the same quality as an oral dose, it seems more amphetamine like (though all of this is massively subjective).
Second dose has not increased the intensity of the experience, but merely prolonged its effect. Still a nice effect, warm, centered and calm. Look forward to a larger dose orally.

Installation
The VMware provider is installed using standard plugin installation procedures. In addition to installing the plugin, a license must be provided so that it can be loaded properly.
To purchase a license, visit the Vagrant VMware provider page. After purchasing a license, a link to download it will be emailed to you. Download this file.
Installing the plugin and license is easy using the vagrant plugin
interface. Both steps are shown below. Note that the plugin name is different depending on the provider you're using. If you're using the Fusion provider, it is vagrant-vmware-fusion
. If you're using the Workstation provider, it is vagrant-vmware-workstation
.
$ vagrant plugin install vagrant-vmware-fusion
...
$ vagrant plugin license vagrant-vmware-fusion license.lic
...
For licensing, the first parameter is the name of the plugin, which is vagrant-vmware-fusion
for the VMware Fusion provider, or vagrant-vmware-workstation
for the VMware Workstation provider. The second parameter is the path to the license itself.
You can verify the license is properly installed by running any Vagrant command, such as vagrant plugin list
. The VMware provider will show an error message if you are missing a license or using an invalid license.
If there are problems installing the plugin, please contact support.

To make web pages load faster, caching is super important. Let's first look at what caching means:
Caching means to store content generated during the request-response cycle and to reuse it when responding to similar requests
(from Rails Guides)
Let's break down what happens when a request is sent to a server to figure out what this all means:
If-None-Match
header304
not modified statusBasically if the page isn't modified, the browser reads the page from the cache.
ETags stands for Entity Tags. It's essentially a key to see if the page has changed or not.
From a client side perspective, this is awesome because now we don't have to re-download everything, everything is stored in the cache.
But from a server side perspective, it still has to generate the ETag every single time there is a request. Processing the entire response body everytime we want to generate an ETag is not the most efficient.
fresh_when
You can set your custom ETags with fresh_when
. For example, let's say you have a blog application and you want to tell rails to update the cache when an article has been updated or created. You can simply add fresh_when
in your controller action. In this case, we're going to add it in the show
action.
What this does is generate an ETag for us like this:
The cache_key
is what keeps track of if something has updated. For instance, @article.cache_key
would look something like 'article/23-2016-224150000'
.
The cache_key
is generated in this format: <model name>/<id>-<updated_at>
.
According to a simple test that thoughtbot ran, performance improved by 94% (33ms to 2ms) just by including one fresh_when
in a controller action. That's an amazing improvement.
As we can see fresh_when
is a powerful tool that we can use to improve our caching. Instead of processing the whole response body, we can focus on tracking if a resource is stale or fresh by using fresh_when
.
Happy coding!
