RDF is a flexible, extensible way to represent information about World Wide Web resources. It is used to represent, among other things, personal information, social networks, metadata about digital artifacts like music and images, as well as provide a means of integration over disparate sources of information. A standardized query language for RDF data with multiple implementations offers developers and end users a way to write and to consume the results of queries across this wide range of information.
This document describes an XML format for the variable binding and boolean results formats provided by the SPARQL query language for RDF, developed by the W3C RDF Data Access Working Group (DAWG), part of the Semantic Web Activity as described in the activity statement .

The
SPARQL Query Language for RDF
[SPARQL-QUERY]
defines several Query Result Forms
(SPARQL Query section 10).
This document defines a SPARQL Results Document
that encodes
the variable binding query results from SELECT
queries
(SPARQL Query section 10.2)
and boolean query results from ASK
queries
(SPARQL Query section 10.5)
in
XML
[XML].
There are two other results formats which follow a similar design but do not use XML: SPARQL 1.1 Query Results JSON Format [SRJ] and SPARQL 1.1 Query Results CSV and TSV Formats [SRC].
Definition: SPARQL Results Document
A SPARQL Results Document is an XML document that is valid with respect to either the RELAX NG XML Schema or the W3C XML Schema in Section 4.
The SPARQL Results Document
begins with sparql
document element in the
http://www.w3.org/2005/sparql-results#
namespace,
written as follows:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> ... </sparql>
Inside the sparql
element are two sub-elements,
head
and
a results element (either results
or boolean
)
which must appear in that order.
The head
element is the first child element of
the sparql
element.
For a variable binding query result, head
must contain a
sequence of elements describing the set of
Query Variable
names in the
Solution Sequence
(here called query results).
The order of the variable names in the sequence is the order of
the variable names given to the argument of the SELECT
statement in the SPARQL query. If SELECT *
is used, the
order of the names is undefined.
Inside the head
element, the ordered sequence of
variable names chosen are used to create empty child elements
variable
with the variable name as the value of an
attribute name
giving a document like this:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> <head> <variable name="x"/> <variable name="hpage"/> <variable name="name"/> <variable name="mbox"/> <variable name="blurb"/> </head> ... </sparql>
For a boolean query result, no elements are required inside
head
and variable
must not be present.
For any query result, head
may also contain
link
child elements with an href
attribute
containing a relative URI that provides a link to some additional
metadata about the query results. The relative URI is resolved
against the in-scope base URI which is usually the query results
format document URI. link
elements must appear after
any variable
elements that are present.
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> <head> ... <link href="metadata.rdf"/> </head> ... </sparql>
The second child-element of sparql
must appear after head
and is either
results
or boolean
.
It is written even if the query results are empty.
The results
element contains the complete sequence of
query results.
For each
Query Solution
in the query results, a result
child-element of results
is added giving
a document like:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> ... head ... <results> <result>... </result> <result>... </result> ... </results> </sparql>
Each result
element corresponds to one Query
Solution in a result and contains child elements (in no particular order) for each Query
Variable that appears in the solution. It
is used to record how the query variables bind to RDF
Terms.
Each binding inside a solution is written as an element
binding
as a child of result
with the query
variable name as the value of the name
attribute. So for a
result binding two variables x and hpage it would
look like:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> <head> <variable name="x"/> <variable name="hpage"/> </head> <results> <result> <binding name="x"> ... </binding> <binding name="hpage"> ... </binding> </result> <result> <binding name="x"> ... </binding> <binding name="hpage"> ... </binding> </result> ... </results> </sparql>
The value of a query variable binding, which is an RDF Term, is
included as the content of the binding
as follows:
<binding><uri>
U</uri></binding>
<binding><literal>
S</literal></binding>
<binding><literal
xml:lang="
L">
S</literal></binding>
<binding><literal
datatype="
D">
S</literal></binding>
<binding><bnode>
I</bnode></binding>
If, for a particular solution, a variable is unbound, no
binding
element for that variable is included in the
result
element.
Note: The blank node label I is scoped to the result set XML document and need not have any association to the blank node label for that RDF Term in the query graph.
An example of a query solution encoded in this format is as follows:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> <head> <variable name="x"/> <variable name="hpage"/> <variable name="name"/> <variable name="age"/> <variable name="mbox"/> <variable name="friend"/> </head> <results> <result> <binding name="x"> <bnode>r2</bnode> </binding> <binding name="hpage"> <uri>http://work.example.org/bob/</uri> </binding> <binding name="name"> <literal xml:lang="en">Bob</literal> </binding> <binding name="age"> <literal datatype="http://www.w3.org/2001/XMLSchema#integer">30</literal> </binding> <binding name="mbox"><EMAIL_ADDRESS></binding> </result> ... </results> </sparql>
A boolean result is written as the element content of a
boolean
child-element of the sparql
element directly after a head
,
containing either true
or false
as follows:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#"> ... head ... <boolean>true</boolean> </sparql>
An example SELECT
SPARQL Query in
example.rq operating
on query graph Turtle/N3 data in data.n3
providing ordered variable binding query results written in XML
in output.srx.
This XML can be transformed into XHTML using the sample XML Query script result-to-html.xq giving output-xquery.html or with XSLT sheet result-to-html.xsl giving output-xslt.html
An example ASK
SPARQL Query in
example2.rq operating
on query graph Turtle/N3 data in data.n3
provides a boolean query result written in XML
in output2.srx.
This XML can be transformed into XHTML using the sample XML Query script result-to-html.xq giving output-xquery2.html or with XSLT sheet result-to-html.xsl giving output-xslt2.html
There are normative XML schemas provided in the following formats:
If W3C XML Schema is used, an xsi:schemaLocation
attribute can be used pointing to the schema as follows:
<?xml version="1.0"?> <sparql xmlns="http://www.w3.org/2005/sparql-results#" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.w3.org/2007/SPARQL/result.xsd"> ... </sparql>
The Internet Media Type / MIME Type for the SPARQL Query Results XML Format is "application/sparql-results+xml".
It is recommended that result files have the extension ".srx" (all lowercase) on all platforms.
It is recommended that result files stored on Macintosh HFS file systems be given a file type of "TEXT".
SPARQL query results uses URIs. See Section 7 of [RFC3986].
SPARQL query results uses IRIs. See Section 8 of [RFC3987].
As this media type uses the "+xml" convention, it shares the same security considerations as described in [RFC3023], section 10.

value such as a surrogate primary key in a relational databaseRealm
application, typically there is only ever one unique principal to retain and that
is the value returned from this method. However, in a multi-Realm
application, where the
PrincipalCollection
might retain principals across more than one realm, the value returned from this
method should be the single principal that uniquely identifies the subject for the entire application.
That value is of course application specific, but most applications will typically choose one of the primary
principals from one of the Realm
s.
Shiro's default implementations of this interface make this
assumption by usually simply returning Iterable.iterator()
.next()
, which just
returns the first returned principal obtained from the first consulted/configured Realm
during the
authentication attempt. This means in a multi-Realm
application, Realm
configuraiton order
matters if you want to retain this default heuristic.
If this heuristic is not sufficient, most Shiro end-users will need to implement a custom
AuthenticationStrategy
. An AuthenticationStrategy
has exact control
over the PrincipalCollection
returned at the end of an authentication attempt via the
AuthenticationStrategy#afterAllAttempts
implementation.

I am Devin Chalmers. I've been working on the web since 2001, I studied math & philosophy at Reed College, graduating in 2008; I've been working mostly in Cocoa ever since. I've managed to make a few pretty cool things, and I hope to write about them here. Every so often I have a thought that I feel bears writing down. Usually I'll put it in a letter to a pretty girl, but the other ones will go here.

We are empowering communication between farms and farmers which are essential in saving them from crop losses and significantly increasing their farming yields.
We are developing a highly efficient framework to empower farmers with pest, disease and weed infestation prediction so that they can take precautionary measures well in advance to avoid crop losses. We collect unique data from their crops using UAVs equipped with Hyperspectral Sensors. These sensors pick up minuscule physiological activities occurring in the crops which are enabled by the data acquisition in the electromagnetic spectrum of 400-1000 nm with more than 100 narrow-bands. We then analyze this data in a co-relation with a spectral database that we are building steadily in the experimental farms of 110 Indian Council for Agriculture Research (ICAR) Institutes. We apply machine learning algorithms to predict the diseases and pest infestation in crops.
This can be understood with a scientific example: When a disease like bacterial blight infects a plant it is caused by a pathogen called Xanthomonas axonopodis pv. punicae. This pathogen releases a number of effector proteins including TAL effectors into the plant through their secretion system. This effector protein causes some biochemical change in the plants and leaves. With human eyes, these changes become visible only when the water absorbing red-brown spots become visible on leaves. We enable the identification of this pathogen at the onset of the infection. Hyperspectral Cameras picks up the humanly invisible color changes occurring in the leaves due to biochemical changes induced by Xanthomonas. Hence, weidentify the disease infestation before a major damage is caused to the plant and becomes visible to naked human eye.

Flink exposes a metric system that allows gathering and exposing metrics to external systems.
You can access the metric system from any user function that extends RichFunction by calling getRuntimeContext().getMetricGroup()
.
This method returns a MetricGroup
object on which you can create and register new metrics.
Flink supports Counters
, Gauges
, Histograms
and Meters
.
A Counter
is used to count something. The current value can be in- or decremented using inc()/inc(long n)
or dec()/dec(long n)
.
You can create and register a Counter
by calling counter(String name)
on a MetricGroup
.
public class MyMapper extends RichMapFunction<String, Integer> {
private Counter counter;
@Override
public void open(Configuration config) {
this.counter = getRuntimeContext()
.getMetricGroup()
.counter("myCounter");
}
@public Integer map(String value) throws Exception {
this.counter.inc();
}
}
Alternatively you can also use your own Counter
implementation:
public class MyMapper extends RichMapFunction<String, Integer> {
private Counter counter;
@Override
public void open(Configuration config) {
this.counter = getRuntimeContext()
.getMetricGroup()
.counter("myCustomCounter", new CustomCounter());
}
}
A Gauge
provides a value of any type on demand. In order to use a Gauge
you must first create a class that implements the org.apache.flink.metrics.Gauge
interface.
There is no restriction for the type of the returned value.
You can register a gauge by calling gauge(String name, Gauge gauge)
on a MetricGroup
.
public class MyMapper extends RichMapFunction<String, Integer> {
private int valueToExpose;
@Override
public void open(Configuration config) {
getRuntimeContext()
.getMetricGroup()
.gauge("MyGauge", new Gauge<Integer>() {
@Override
public Integer getValue() {
return valueToExpose;
}
});
}
}
public class MyMapper extends RichMapFunction[String,Int] {
val valueToExpose = 5
override def open(parameters: Configuration): Unit = {
getRuntimeContext()
.getMetricGroup()
.gauge("MyGauge", ScalaGauge[Int]( () => valueToExpose ) )
}
...
}
Note that reporters will turn the exposed object into a String
, which means that a meaningful toString()
implementation is required.
A Histogram
measures the distribution of long values.
You can register one by calling histogram(String name, Histogram histogram)
on a MetricGroup
.
public class MyMapper extends RichMapFunction<Long, Integer> {
private Histogram histogram;
@Override
public void open(Configuration config) {
this.histogram = getRuntimeContext()
.getMetricGroup()
.histogram("myHistogram", new MyHistogram());
}
@public Integer map(Long value) throws Exception {
this.histogram.update(value);
}
}
Flink does not provide a default implementation for Histogram
, but offers a Wrapper that allows usage of Codahale/DropWizard histograms.
To use this wrapper add the following dependency in your pom.xml
:
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-metrics-dropwizard</artifactId>
<version>1.4-SNAPSHOT</version>
</dependency>
You can then register a Codahale/DropWizard histogram like this:
public class MyMapper extends RichMapFunction<Long, Integer> {
private Histogram histogram;
@Override
public void open(Configuration config) {
com.codahale.metrics.Histogram histogram =
new com.codahale.metrics.Histogram(new SlidingWindowReservoir(500));
this.histogram = getRuntimeContext()
.getMetricGroup()
.histogram("myHistogram", new DropwizardHistogramWrapper(histogram));
}
}
A Meter
measures an average throughput. An occurrence of an event can be registered with the markEvent()
method. Occurrence of multiple events at the same time can be registered with markEvent(long n)
method.
You can register a meter by calling meter(String name, Meter meter)
on a MetricGroup
.
public class MyMapper extends RichMapFunction<Long, Integer> {
private Meter meter;
@Override
public void open(Configuration config) {
this.meter = getRuntimeContext()
.getMetricGroup()
.meter("myMeter", new MyMeter());
}
@public Integer map(Long value) throws Exception {
this.meter.markEvent();
}
}
Flink offers a Wrapper that allows usage of Codahale/DropWizard meters.
To use this wrapper add the following dependency in your pom.xml
:
<dependency>
<groupId>org.apache.flink</groupId>
<artifactId>flink-metrics-dropwizard</artifactId>
<version>1.4-SNAPSHOT</version>
</dependency>
You can then register a Codahale/DropWizard meter like this:
public class MyMapper extends RichMapFunction<Long, Integer> {
private Meter meter;
@Override
public void open(Configuration config) {
com.codahale.metrics.Meter meter = new com.codahale.metrics.Meter();
this.meter = getRuntimeContext()
.getMetricGroup()
.meter("myMeter", new DropwizardMeterWrapper(meter));
}
}
Every metric is assigned an identifier under which it will be reported that is based on 3 components: the user-provided name when registering the metric, an optional user-defined scope and a system-provided scope.
For example, if A.B
is the system scope, C.D
the user scope and E
the name, then the identifier for the metric will be A.B.C.D.E
.
You can configure which delimiter to use for the identifier (default: .
) by setting the metrics.scope.delimiter
key in conf/flink-conf.yaml
.
You can define a user scope by calling either MetricGroup#addGroup(String name)
or MetricGroup#addGroup(int name)
.
counter = getRuntimeContext()
.getMetricGroup()
.addGroup("MyMetrics")
.counter("myCounter");
The system scope contains context information about the metric, for example in which task it was registered or what job that task belongs to.
Which context information should be included can be configured by setting the following keys in conf/flink-conf.yaml
.
Each of these keys expect a format string that may contain constants (e.g. “taskmanager”) and variables (e.g. “<task_id>”) which will be replaced at runtime.
metrics.scope.jm
metrics.scope.jm.job
metrics.scope.tm
metrics.scope.tm.job
metrics.scope.task
metrics.scope.operator
There are no restrictions on the number or order of variables. Variables are case sensitive.
The default scope for operator metrics will result in an identifier akin to localhost.taskmanager.1234.MyJob.MyOperator.0.MyMetric
If you also want to include the task name but omit the task manager information you can specify the following format:
metrics.scope.operator: <host>.<job_name>.<task_name>.<operator_name>.<subtask_index>
This could create the identifier localhost.MyJob.MySource_->_MyOperator.MyOperator.0.MyMetric
.
Note that for this format string an identifier clash can occur should the same job be run multiple times concurrently, which can lead to inconsistent metric data. As such it is advised to either use format strings that provide a certain degree of uniqueness by including IDs (e.g <job_id>) or by assigning unique names to jobs and operators.
Metrics can be exposed to an external system by configuring one or several reporters in conf/flink-conf.yaml
. These
reporters will be instantiated on each job and task manager when they are started.
metrics.reporters
: The list of named reporters.metrics.reporter.<name>.<config>
: Generic setting <config>
for the reporter named <name>
.metrics.reporter.<name>.class
: The reporter class to use for the reporter named <name>
.metrics.reporter.<name>.interval
: The reporter interval to use for the reporter named <name>
.metrics.reporter.<name>.scope.delimiter
: The delimiter to use for the identifier (default value use metrics.scope.delimiter
) for the reporter named <name>
.All reporters must at least have the class
property, some allow specifying a reporting interval
. Below,
we will list more settings specific to each reporter.
Example reporter configuration that specifies multiple reporters:
metrics.reporters: my_jmx_reporter,my_other_reporter
metrics.reporter.my_jmx_reporter.class: org.apache.flink.metrics.jmx.JMXReporter
metrics.reporter.my_jmx_reporter.port: 9020-9040
metrics.reporter.my_other_reporter.class: org.apache.flink.metrics.graphite.GraphiteReporter
metrics.reporter.my_other_reporter.host: <IP_ADDRESS>
metrics.reporter.my_other_reporter.port: 10000
Important: The jar containing the reporter must be accessible when Flink is started by placing it in the /lib folder.
You can write your own Reporter
by implementing the org.apache.flink.metrics.reporter.MetricReporter
interface.
If the Reporter should send out reports regularly you have to implement the Scheduled
interface as well.
The following sections list the supported reporters.
You don’t have to include an additional dependency since the JMX reporter is available by default but not activated.
Parameters:
port
- (optional) the port on which JMX listens for connections. This can also be a port range. When a
range is specified the actual port is shown in the relevant job or task manager log. If this setting is set
Flink will start an extra JMX connector for the given port/range. Metrics are always available on the default
local JMX interface.Example configuration:
metrics.reporters: jmx
metrics.reporter.jmx.class: org.apache.flink.metrics.jmx.JMXReporter
metrics.reporter.jmx.port: 8789
Metrics exposed through JMX are identified by a domain and a list of key-properties, which together form the object name.
The domain always begins with org.apache.flink
followed by a generalized metric identifier. In contrast to the usual
identifier it is not affected by scope-formats, does not contain any variables and is constant across jobs.
An example for such a domain would be org.apache.flink.job.task.numBytesOut
.
The key-property list contains the values for all variables, regardless of configured scope formats, that are associated
with a given metric.
An example for such a list would be host=localhost,job_name=MyJob,task_name=MyTask
.
The domain thus identifies a metric class, while the key-property list identifies one (or multiple) instances of that metric.

By default Flink gathers several metrics that provide deep insights on the current state. This section is a reference of all these metrics.
The tables below generally feature 4 columns:
The “Scope” column describes which scope format is used to generate the system scope. For example, if the cell contains “Operator” then the scope format for “metrics.scope.operator” is used. If the cell contains multiple values, separated by a slash, then the metrics are reported multiple times for different entities, like for both job- and taskmanagers.
The (optional)”Infix” column describes which infix is appended to the system scope.
The “Metrics” column lists the names of all metrics that are registered for the given scope and infix.
The “Description” column provides information as to what a given metric is measuring.
Note that all dots in the infix/metric name columns are still subject to the “metrics.delimiter” setting.
Thus, in order to infer the metric identifier:

Flink allows to track the latency of records traveling through the system. To enable the latency tracking
a latencyTrackingInterval
(in milliseconds) has to be set to a positive value in the ExecutionConfig
.
At the latencyTrackingInterval
, the sources will periodically emit a special record, called a LatencyMarker
.
The marker contains a timestamp from the time when the record has been emitted at the sources.
Latency markers can not overtake regular user records, thus if records are queuing up in front of an operator,
it will add to the latency tracked by the marker.
Note that the latency markers are not accounting for the time user records spend in operators as they are bypassing them. In particular the markers are not accounting for the time records spend for example in window buffers. Only if operators are not able to accept new records, thus they are queuing up, the latency measured using the markers will reflect that.
All intermediate operators keep a list of the last n
latencies from each source to compute
a latency distribution.
The sink operators keep a list from each source, and each parallel source instance to allow detecting
latency issues caused by individual machines.
Currently, Flink assumes that the clocks of all machines in the cluster are in sync. We recommend setting up an automated clock synchronisation service (like NTP) to avoid false latency results.
Metrics that were gathered for each task or operator can also be visualized in the Dashboard. On the main page for a
job, select the Metrics
tab. After selecting one of the tasks in the top graph you can select metrics to display using
the Add Metric
drop-down menu.
<subtask_index>.<metric_name>
.<subtask_index>.<operator_name>.<metric_name>
.Each metric will be visualized as a separate graph, with the x-axis representing time and the y-axis the measured value. All graphs are automatically updated every 10 seconds, and continue to do so when navigating to another page.
There is no limit as to the number of visualized metrics; however only numeric metrics can be visualized.

The MoonA Natural SatelliteThe Moon is the only natural satellite of the Earth, and the fifth largest satellite in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary, having a quarter the diameter of Earth but only 1⁄81 its' mass. Statistics
Moon Landings
Apollo 11 was an American spaceflight in which the astronauts Neil Armstrong and Buzz Aldrin became the first ever to land on the Moon on July 20, 1969, at 20:18 UTC. Further, Neil Armstrong became the first to step onto the Moon 6 hours after the landing on 21 July, 02:56 UTC. Source: http://en.wikipedia.org/wiki/Apollo_11 Apollo 12 was the sixth manned flight in the United States Apollo program and the second to land on the Moon (an H type mission). It was launched on November 14, 1969 from the Kennedy Space Center, Florida, four months after Apollo 11. Source: http://en.wikipedia.org/wiki/Apollo_12 |


claiming ~net
The quoted material comes from an email sent by Curtis Yarvin-- my reply is in-line.
The general idea of Urbit has always been to use the potential value of the namespace to drive its development. Partly this involves doing what we've done, which is to create a company and get funding from evil VCs. But fundamentally, Urbit remains an open-source project - for example, there is no secret codebase - and we can't really succeed without public contributions.
Urbit is a labor of love, and I'd like to see it go far. Cosmic, even. I doubt anyone will begrudge you for acting within the guidelines of today's Corporations-Are-People mindset, especially since the entire operation has been transparent since the beginning.
Basically, as in all open-source projects, people have contributed and will contribute to Urbit, because Urbit is cool and fun. If they are in a sense being paid, or expected to be paid, for this work, Urbit becomes less cool and fun. So we don't want to see the real estate as in any sense a bounty, a payment, a prize, etc, etc. A crucial element of the scheme is that those who win, win without any prior expectation of winning. This preserves the fun factor. I hope.
The fun, for me, is in helping to create a virtual world, from scratch, using no more than some simple mechanical rules. Urbit is fun, and I'm pleased by how well my contributions have been accepted. This is already rewarding, though, of course, I'm not saying 'no' to a carrier.
Owning an Urbit carrier is more than just a reward - it is also a duty. Urbit is a digital republic, and as a carrier owner you are literally a senator of this republic. For the moment, of course, the republic is tiny and it does not need republican government - it needs a dictator. As it grows and succeeds, its governance must and will become not only republican, but even democratic. I hope this doesn't shock anyone.
It seems clear that those who accept this duty (you can always decline) should be defined by one word: virtue. A virtuous republic is impossible without virtuous governors.
One time, I was talking about Urbit, and someone summarized it as "It sounds like you're kind of important in this imaginary world." I shouldn't let this talk get to my head, but it gets difficult when you send out messages about how important my participation can be. ;) Now I get to talk about being a Rear Admiral in the Urbit Republic, or something along those lines.
Therefore, I've decided to issue urbit.org carriers in the following way: distribution is in rounds, each of which is defined by a previously unannounced virtue. For instance, in 2010, I committed to issuing carriers to anyone who could write decrement in Nock. I promised a prize to be disclosed later. I don't think anyone had any idea that this prize would be something you could sell (please don't, though!) for over $10,000.
"You can't even buy these for dollars," Y.T. says, of her skateboard. I'm humbled by this reward, and to sell it would be completely contrary to the virtue expected of us<EMAIL_ADDRESS>is certainly a number, but its type isn't compatible with ++zeno.
All this is to say that I'll take this duty seriously.  Urbit is easy, uncomplicated, and fun, but fun can't exist without some serious work behind it.
What was the virtue of the 2010 winners? One of the classic virtues - luck. They did the right thing in the right place at the right time. Hence, in the carrier database their carriers are listed as "per fortuna."
It still surprises me that Nock, as we know it, has been around this long. We live in a culture where something from 3 months ago is considered old news, which makes the `fortuna' carrier-holders ancient...
In this round we're celebrating a different virtue - loyalty to Urbit. Your carrier is "per fidelis." This reflects the fact that for the last three months, more or less, you have showed up, chatted, evangelized, sent bug reports, worked through the doc, etc, etc, etc. Without any expectation of being rewarded for this, obviously. It is the lack of expectation that makes the reward genuinely effective, and not overjustified. I hope.
The experience of poking around in this digital labyrinth is utterly addictive. Even without the potential for reward, Urbit would hold my attention, so the reward is indeed effective. (I hope.)
Unless you are a present carrier holder, feel free to look through ++zeno and pick any carrier that is presently assigned to me or to Tlon, other than ~zod of course. We'll adjust the bindings as needed.
I like the idea of holding carrier ~net, `@p`79. The associations for that number are mostly favorable, and I won't belabor the point by listing them all out.
As a final note. I recognize that having a carrier means giving up most of the privacy I sought in the atax1a mask, but that privacy was illusory (and orthogonal to Urbit) anyway. This is the price of living in our modern world.

Installing kubernetes using kismatic.¶
Note
We recommend using kismatic to install kubernetes, although users are free to install kubernetes cluster using their own prefered method as well.
Pre-Requisites¶
- 3 RHEL 7.2 nodes with atleast 8GB memory
- All machines should be resolvable by hostnames
- A user account with passwordless ‘sudo’ access on all the nodes.
Installation¶
- Setting up new useraccount on RHEL nodes
Create a new user account on all RHEL nodes using following command :-
>useradd kubernetes
- Set a password for this newly created user
>passwd kubernetes
- Set a passwordless ssh access between all hosts
>ssh-keygen -t rsa
- Copy the generated key to other hosts using ssh-copy-id
>ssh-copy-id -i ~/.ssh/mypublickey kubernetes@host1 >ssh-copy-id -i ~/.ssh/mypublickey kubernetes@host2 >ssh-copy-id -i ~/.ssh/mypublickey kubernetes@host3
- Setup passwordless sudo for the newly created user by editing /etc/sudoers
>nano /etc/sudoersAppend the following line at the end of /etc/sudoers
kubernetes ALL = (ALL) NOPASSWD: ALL
- Turn swap off on all linux machines
> swapoff -a
Install kismatic as per following documentation.
A sample installation yaml file is described here.
Download and install helm package manager

The March 13 issue of Science carried an article claiming, on the basis of a report from the General Accounting Office (GAO), that a "minute mathematical error ... allowed an Iraqi Scud missile to slip through Patriot missile defenses a year ago and hit U.S. Army barracks in Dhahran, Saudi Arabia, killing 28 servicemen." The article continues with a readable account of what happened.
The article says that the computer doing the tracking calculations had an internal clock whose values were slightly truncated when converted to floating-point arithmetic. The errors were proportional to the time on the clock: 0.0275 seconds after eight hours and 0.3433 seconds after 100 hours. A calculation shows each of these relative errors to be both very nearly 2-20, which is approximately 0.0001%.
The GAO report contains some additional information. The internal clock kept time as an integer value in units of tenths of a second, and the computer's registers were only 24 bits long. This and the consistency in the time lags suggested that the error was caused by a fixed-point 24-bit representation of 0.1 in base 2. The base 2 representation of 0.1 is nonterminating; for the first 23 binary digits after the binary point, the value is 0.1 × (1 - 2-20). The use of 0.1 × (1 - 2-20) in obtaining a floating-point value of time in seconds would cause all times to be reduced by 0.0001%.
This does not really explain the tracking errors, however, because the tracking of a missile should depend not on the absolute clock-time but rather on the time that elapsed between two different radar pulses. And because of the consistency of the errors, this time difference should be in error by only 0.0001%, a truly insignificant amount.
Further inquiries cleared up the mystery. It turns out that the hypothesis concerning the truncated binary representation of 0.1 was essentially correct. A 24-bit representation of 0.1 was used to multiply the clock-time, yielding a result in a pair of 24-bit registers. This was transformed into a 48-bit floating-point number. The software used had been written in assembly language 20 years ago. When Patriot systems were brought into the Gulf conflict, the software was modified (several times) to cope with the high speed of ballistic missiles, for which the system was not originally designed.
At least one of these software modifications was the introduction of a subroutine for converting clock-time more accurately into floating-point. This calculation was needed in about half a dozen places in the program, but the call to the subroutine was not inserted at every point where it was needed. Hence, with a less accurate truncated time of one radar pulse being subtracted from a more accurate time of another radar pulse, the error no longer cancelled.
In the case of the Dhahran Scud, the clock had run up a time of 100 hours, so the calculated elapsed time was too long by 2-20 × 100 hours = 0.3433 seconds, during which time a Scud would be expected to travel more than half a kilometer.
The roundoff error, of course, is not the only problem that has been identified: serious doubts have been expressed about the ability of Patriot missiles to hit Scuds.

Experimental data derived from the analysis of the design decoys can be added and processed through the library. For some experiments, like
Circular Dichroism or Surface Plasmon Resonance, very specific formats exist. In those cases, the proper parser (read_CD()
or
read_SPR()
) exists. Other cases provide different +*CSV* files. This can be imported to python with read_csv()
, but might
need to be post-processed to work with them.
Each plotting function shows in its documentation the exact naming of the column that it expects.
Circular dichroism data can be easily worked with.
Currently the library can automatically import data compatible with the Jasco J-815
series by means of the read_CD()
function, but any data can be read as long as it finally produces a DataFrame
with, at least, the following
two columns:
| Column Name | Data Content |
|---|---|
| Wavelength | Wavelength (nm). |
| MRE | Value at each wavelength (10 deg^2 cm^2 dmol^-1). |
Adding a new available format to the library would be as easy as adding the appropriate private function to rstoolbox/io/experimental
and provide access to
it through the read_CD()
function.
Note
When loading data with read_CD()
notice that the DataFrame
contains extra columns with extra information. From those, Temp
is the more relevant for
plotting and analysis, as is the one that allows to separate the different data series.
Currently, CD data can be obtained and plotted such as:
In [1]: import rstoolbox as rs
...: dfCD = rs.io.read_CD("../rstoolbox/tests/data/CD", model='J-815')
...: dfCD.columns
...:
Out[1]: Index(['Wavelength', 'MRE', 'voltage', 'title', 'bin', 'minw', 'Temp'], dtype='object')
In [2]: import matplotlib.pyplot as plt
...: fig = plt.figure(figsize=(10, 6.7))
...: ax = plt.subplot2grid((1, 1), (0, 0), fig=fig)
...: rs.plot.plot_CD(dfCD, ax, sample=6)
...:
In [3]: plt.show()
Tip
Depending on how many temperatures one might have, trying to plot all of them will create a very large legend. One can either delete it or use the sample
option, which
uses the Bresenham’s line algorithm to sample temperatures across all possible
As before, thermal melt data can be loaded by properly parsing any input file as long as the generated DataFrame
contains at least the following columns:
| Column Name | Data Content |
|---|---|
| Temp | Temperatures (celsius). |
| MRE | Value at each temperature (10 deg^2 cm^2 dmol^-1). |
If loaded from CD data containing a temp column (as is the case when loaded with read_CD()
), one can directly pick the data from there:
In [4]: dfTM = dfCD[(dfCD['Wavelength'] == 220)]
...: fig = plt.figure(figsize=(10, 6.7))
...: ax = plt.subplot2grid((1, 1), (0, 0), fig=fig)
...: rs.plot.plot_thermal_melt(dfTM, ax)
...:
In [5]: plt.show()
For well-behaved proteins, the library can approximate the melting point.
In [6]: fig = plt.figure(figsize=(10, 6.7))
...: ax = plt.subplot2grid((1, 1), (0, 0), fig=fig)
...: rs.plot.plot_thermal_melt(dfTM, ax, fusion_temperature=True, temp_marker=True)
...:
In [7]: plt.show()
MALS data can be manually loaded or read through the read_MALS()
function.
In order to properly work with the plotting functions, it needs to have at least two of the following columns:
| Column Name | Data Content |
|---|---|
| Time | Time (min). |
| UV | UV data (V). |
| LS | Light Scattering data (V). |
| MW | Molecular Weight (Daltons). |
being Time always mandatory. Depending on the amount of data, the plot function can pick which information to print.
In [8]: import pandas as pd
...: dfMALS = pd.read_csv("../rstoolbox/tests/data/mals.csv")
...: fig = plt.figure(figsize=(10, 6.7))
...: ax = plt.subplot2grid((1, 1), (0, 0))
...: rs.plot.plot_MALS(dfMALS, ax)
...:
In [9]: plt.show()
Optimal SPR data has to contain the fitted curves on input, but can be read directly from the default output of the machine.
More details on the format are listed in the corresponding function read_SPR()
.
The fitted curves will be directly represented with plot_SPR()
.
In [10]: dfSPR = rs.io.read_SPR("../rstoolbox/tests/data/spr_data.csv.gz")
....: fig = plt.figure(figsize=(10, 6.7))
....: ax = plt.subplot2grid((1, 1), (0, 0))
....: rs.plot.plot_SPR(dfSPR, ax, datacolor='black', fitcolor='red')
....:
In [11]: plt.show()
In [12]: plt.close('all')
Individual raw FASTQ data obtained from deep sequencing can be directly read with the read_fastq()
function.
In order to evaluate the enrichment of different outputs submitted to a different experimental conditions in different
concentrations, and provide the min
and max
concentrations to use for the calculus to sequence_enrichment()
.
In [13]: indat = {'binder1': {'conc1': '../rstoolbox/tests/data/cdk2_rand_001.fasq.gz',

Maputo is the capital of Mozambique and lies about 70nm north of the border with South Africa. It is a major commercial port.
Richards Bay is approximately a 200 miles sail away.
Position 21°0'S, 032°38'E (off the harbour entrance)
This is an official port of entry
Port control maintain continuous watch on VHF Channel 16. It is possible to come alongside one of the wharfs for clearance formalities.
If not planning to step ashore, there is no requirement to to officially clear in.
Last updated January 2016.
The harbour is approached through two main channels, the south channel being recommended only for small vessels and those with local knowledge. The buoyage into Maputo is all well maintained, well lit at night, and easy to follow.
If just making a brief stop here to wait out strong winds, then there is a useful anchorage at approximately 25° 57.6'S, 032° 31.4'E.

Hello and welcome! My name is Kaitlyn and I'm so happy you're here. As we both know, living with ADHD in a world not built for our squiggly brains can be really tough. But that's where I come in. If you're struggling with executive functioning, self-regulation, self-esteem or anything else ADHD related, let me help. I work with clients to help them live happier, more efficient, fulfilling lives.
As a kid, I was always told I was too loud, too talkative, too energetic. I tried to stuff that all down to fit the mold that society built for us but I simply could not. And as a result, I spent lots of time upset at myself, procrastinating, panicking and a lot of fun verbs that I'm sure a lot of you can relate to. So, as someone who was always told she was "too much," my mission is to help my clients realize how incredible and expansive they are, to see neurodivergence as a gift and to create systems that work for them.
If you're feeling stuck and don't know where to turn, you don't have to face this alone. I think each of us needs a support system to truly flourish and I want to be that person for you. Through our work together we can help you build the life you want and deserve. Reach out to me when you're ready for a complimentary consultation.

Flight evacuated after intruder boards plane without a passport or boarding pass
Horrified passengers were forced off the jet after the man locked himself in the toilet after he was confronted by an air hostess on the Vueling flight from Barcelona to Dublin
by Darragh Berry, Lorraine KingA flight has been evacuated after a man stormed on board without a passport or boarding pass.
Horrified passengers were forced off the jet at Barcelona Airport as the intruder locked himself in the plane's toilet when he was confronted by an air hostess.
The Vueling flight VY 8720 from Barcelona to Dublin was due to take off at 12.40pm but the chaos ensued after security is said to have been tipped-off that someone had boarded the plane illegally
Passengers Mark Megarry and Paul Steward told Dublin Live how the man ran into the toilet when he was questioned by the airline worker.
They said: "Apparently police and security got word that someone had boarded the plane that shouldn't have.
"An air hostess began asking everyone on the plane for their boarding passes and passports.
"The man was sitting in front of us and after the air hostess had checked ours, he jumped up out of his seat and ran.
"He pushed his way past the air hostess. A passenger near the back jumped out of their seat and tried to stop him also but he pushed them out of the way too and locked himself in the bathroom.
"Passengers began to panic then as they thought there was a bomb threat or something."
The plane was at a standstill in Spain while security tried to coax the man out of the toilet
He has since been removed and is being held by police.
They added: "We have to all re-check back in now again at the airport. Police came on the plane and stood at the door of the toilet as they try to persuade the man to come out."
A spokeswoman for Vueling Airline told Mirror Online: "During the boarding process of flight BCN-DUB VY8720 in Barcelona, gate agents identified a passenger trying to board this flight with a false passport.
"Whilst waiting for the arrival of the authorities, this person managed to run towards the aircraft toilet and lock himself therein.
"Vueling disembarked all passengers safely and proceeded to change aircraft so our customers were able to continue their journey to their destination.
"There was no impact on passengers and cabin crew and the local authorities are in full charge of the situation."

KeukaCap establishes a personal investment plan for your account, based on your goals, finances, and lifestyle.
KeukaCap constructs an investment portfolio for you and provides ongoing portfolio management. We help you open your brokerage account, identify an appropriate asset allocation, and recommend specific stocks, bonds, and exchange traded funds (“ETF”) investments for your account.
KeukaCap is incubating an investment fund focused on maximizing long-term returns that will be available to select clients.
KeukaCap establishes your investment plan, helps you open a brokerage account, and constructs your investment portfolio. We recommend an asset allocation and execute that allocation by investing directly in individual stocks, bonds, and ETF's. This allows clients to hold a more concentrated portfolio of under-valued securities and makes executing your investment plan more efficient. We are accountable to our clients for our investment plans, asset allocation decisions, and security recommendations.
All investments are made within your personal brokerage account. This eliminates the costs associated with large fund bureaucracies and provides you immediate access to and control of your money. You also benefit from a clearer understanding of what companies you are investing in, a level of transparency that rarely exists with large funds.
KeukaCap charges annual fees equal to 0.5% of money under management. So for every $10,000 managed by KeukaCap, we are paid $50 annually. Most investment advisors charge 1.0%-2.0% annually, and some have upfront fees as high as 5.0%. Paying lower fees leads to significantly higher investment returns, as fee savings are reinvested and compound over time.
Few investment advisors are trained to both construct and execute an investment plan. KeukaCap's founder is a Chartered Financial Analyst (CFA), a member of the New York Society of Security Analysts (NYSSA), a former sell-side equity research analyst, and has experience in both consulting and corporate finance. He has been managing money for over ten years.
KeukaCap embraces the highest ethical standards in all business endeavours. We value our brand name and reputation over all else. Your best interests are our priority and our primary objective is to achieve your investment goals, as laid out in your personal investment plan.
KeukaCap does not engage in day-trading or derivative investing. Our investment approach dictates that we focus on the long-term prospects of a business and identify undervalued companies that will appreciate considerably over the long-term. We favor diversified, conservative portfolios that typically outperform during bear markets and underperform during bull markets.
KeukaCap’s founder begins managing personal and family money while working in consulting full-time. Markets are nearing all-time highs. Due to his value-oriented approach, few stocks make the cut. The following 2008-2009 downturn punishes many investors. He counsels family investors through the downturn, urging them to hang tight or add to their stock positions.
KeukaCap’s founder gains valuable fundamental equity analysis experience while researching aerospace and defense stocks under a former Northrop Grumman aerospace engineer/Goldman Sachs lead analyst. But the sell-side’s short term focus disagrees with him. He continues managing his own money, with a long-term, value orientation.
KeukaCap’s founder begins managing family money while gaining valuable corporate finance and operations experience at Ports America. The seeds of Keuka Capital are planted. Keuka Capital begins incubating a total return investment fund with the goal of outperforming the S&P 500 over five to ten year periods.
KeukaCap launches its separately managed account service for individual investor clients.

Save/Load model weights using HDF5 files
save_model_weights_hdf5(object, filepath, overwrite = TRUE)
load_model_weights_hdf5(
object,
filepath,
by_name = FALSE,
skip_mismatch = FALSE,
reshape = FALSE
)
| object | Model object to save/load |
| filepath | Path to the file |
| overwrite | Whether to silently overwrite any existing file at the target location |
| by_name | Whether to load weights by name or by topological order. |
| skip_mismatch | Logical, whether to skip loading of layers
where there is a mismatch in the number of weights, or a mismatch in the
shape of the weight (only valid when |
| reshape | Reshape weights to fit the layer when the correct number of values are present but the shape does not match. |
The weight file has:
layer_names
(attribute), a list of strings (ordered names of model layers).
For every layer, a group
named layer.name
For every such layer group, a group attribute weight_names
, a list of strings
(ordered names of weights tensor of the layer).
For every weight in the layer, a dataset storing the weight value, named after the weight tensor.
For load_model_weights()
, if by_name
is FALSE
(default) weights are
loaded based on the network's topology, meaning the architecture should be
the same as when the weights were saved. Note that layers that don't have
weights are not taken into account in the topological ordering, so adding
or removing layers is fine as long as they don't have weights.
If by_name
is TRUE
, weights are loaded into layers only if they share
the same name. This is useful for fine-tuning or transfer-learning models
where some of the layers have changed.
