Listen to your sore muscles when they beg for rest.
There is no formula for what you can do to help your muscles recover from a race. The length of your recovery time will depend on your overall condition going into the race.
For a few days after the race, expect your muscles to be sore and your body tired. The soreness you feel is caused by damage done to your muscles (the contracting and lengthening) during the race. You may even have delayed muscle soreness that can begin as late as two to three days after the race and last up to a few days.
Helpful hints for treating sore muscles:
You shouldn't resume running until your soreness has gone away. The cure for most post-race soreness and stiffness is REST. If, after about a week and a half, you still fail to feel better, seek professional medical help.

How-To
By Sam Roberts
Config File Syntax
The config file is config.ru
if none is specified.
Handling of config files depends on whether it’s .ru
, or something
else. It’s important to define the application that rackup
will run
correctly; failure to do so will result in mysterious runtime errors!
With a .ru
config file
The config file is treated as if it is the body of
app = Rack::Builder.new { … config_file_content_here … }.to_app
Also, the first line starting with #\
is treated as if it were
command-line options, allowing rackup
arguments to be specified in the
config file. For example:
#\ -w -p 8765
use Rack::Reloader, 0
use Rack::ContentLength
app = proc do |env|
[200, {'Content-Type' => 'text/plain'}, ['a']]
end
run app
Would run with Ruby warnings enabled, and request port 8765.
(Detail: the -p
option will be ignored unless the server supports the
:Port
option.)
With a .rb
, etc config file
The config file is required. It must assign the app to a global constant
so rackup
can find it.
The name of the constant should be config file’s base name, stripped of
a trailing .rb
(if present), and capitalized. The following config
files all look for Config
:
~/bin/config
config.rb
/usr/bin/config
example/config.rb
This will work if the file name is octet.rb
:
Octet = Rack::Builder.new do
use Rack::Reloader, 0
use Rack::ContentLength
app = proc do |env|
[ 200, { 'Content-Type' => 'text/plain' }, ['b']]
end
run app
end.to_app
Auto-Selection of a Server
The specified server (from Handler.get
) is used, or the first of these
to match is selected:
PHP_FCGI_CHILDREN
is in the process environment, use FastCGI- Rack::REQUEST_METHOD is in the process environment, use CGI
- If Puma is installed, use that
- If Thin is installed, use that
- If falcon is installed, use that
- Otherwise, use WEBRick
Automatic Middleware
rackup
will automatically use some middleware, depending on the
environment you select, the -E
switch, with development
being the
default:
development
: CommonLogger, ShowExceptions, Lintdeployment
: CommonLoggernone
: none
CommonLogger isn’t used with the CGI server, because it writes to
stderr
, which doesn’t interact so well with CGI.

You can easily predict that Media Bricks are the most awesome bricks among all the bricks we have seen before. It is really cool than any other. The awesome list of the Media bricks are as follows.
- Button Grid
- Camera
- Drawing Canvas
- Line Graph
- NoteBook
- To-do List
You can see all are some of the awesome elements and we need them in our daily life almost. So it is more interesting than any other.
Button Grid
Here we can have Grid of button say N * M buttons. We can give name to each and every button. The naming starts from top left and ends in the bottom right. We can also capture upto 1st 9 buttons tapped, and also for each and every button we can get the index and also the value which we have give. For the buttons colors we have color palette. And there is also color for text.
Camera
It is used for capturing the photo with the help of the Webcam. We can also send the captured photo as a output.
Drawing canvas
It is used to draw some rough sketches. We can give the height of the drawing area and also we can increase the size of the brush. After we finish our drawing we can also make it read only.
Note Book
It is used to take down the important things which we would like to write down. We can change the background color and notes color. We can give various action like new page, next page, previous page, delete page, write text, give image and add HTML. It is an interesting thing in this section.
To-do List
It is used to write down the list of things we would like to write and then after we finish we can make it done. The input is usually the text which has to be done, and the output is which is finished.
Line graph
It is used to generate a simple line graph with the help of various input number.


So, for the last ChiPy meeting I gave a presentation on py.test. I converted the Dive Into Python unittest example. Along the way I found what I thought was a good use of decorators to provide multiple parameters for a testing function. Without decorators this is what it would look like:
known_values = [(1, 'i'), (2, 'ii'), ...] def test_to_roman(): for integer, numeral in known_values: yield real_test_to_roman, integer, numeral def real_test_to_roman(integer, numeral): assert roman.toRoman(integer) == numeral
That's not bad (easier than unittest, to be sure), but here's the decorator I made, for equivalent effect:
def param(param_list): def decorator(func): def yielder(): for params in param_list: yield (func,) + params return yielder return decorator @param(known_values) def test_to_roman(integer, numeral): assert roman.toRoman(integer) == numeral
I thought, oh! how clever I am to come up with this example of decorators just when Python 2.4 is coming out, and to tie it into the month's topic (testing). I expected everyone to say my, how easy and useful these decorators are!
I didn't get quite that reaction. And I must admit, when people weren't sure what this did, my explanation made it clear this wasn't going to be immediately intuitive to people. This is more or less the explanation I gave:
The decorator line -- the line with the at sign -- is an expression that is evaluated. In this case the expression returns a function. Then it gets called with the function, and returns a generator function, and that generator function is what the name of the original function is bound to. Ta-da!
I actually went on longer than that, hoping that by noting that the original function is still around (bound to func) and describing the order of execution and a couple other things that it would magically become clear. It probably only made it worse.
I hope with a little thought and visual inspection that people can figure out the param decorator -- I think it will be a common pattern for decorators. Maybe the what's new document will be easier to understand. There's a real benefit to writing your own decorators; this particular example is only useful for tests, and only for py.test tests at that. I expect other domains to call for other decorators -- indeed, we are seeing a lot of clever uses of them in the Python Cookbook. They don't provide any new functionality, but they make a certain pattern feel much nicer.
But when it comes to explaning a decorator, it's clearly difficult. This was the same problem I've had explaining WSGI, which also involves lots of functions that return functions and call functions and whatnot. I think coming up with better names than "a function" will be important. In this case, emphasizing that param builds a decorator, which we call "decorator" (not "a function that takes a function and returns a function"). And maybe instead of "yielder" it should be "replacement_func" or something. I'm finding the use of language becomes very important when dealing with higher-order functions.
Update: There was quite a bit of discussion on the ChiPy mailing list about this, and perhaps some resolution and understanding. You can start reading the thread here. Adrian Holavaty wrote a good example of decorators as well.

The AugLagrangian class implements the Augmented Lagrangian method of optimization.
In this scheme, a penalty term is added to the Lagrangian. This method is also called the "method of multipliers".
The template class LagrangianFunction must implement the following five methods:
The number of constraints must be greater than or equal to 0, and EvaluateConstraint() should evaluate the constraint at the given index for the given coordinates. Evaluate() should provide the objective function value for the given coordinates.

This system prevents the impersonation of a joining node through encryption and singatures.
If one node has faulty member information, the consensus system would still not allow a new node to join, since that faulty node will check with it's two adjacent nodes and lose majority confirmation. Given this check with two other nodes, we can say that up to 1/3 of the nodes can be compromised and the system could still work if ideally organized.
Injection of faulty information could only be accomplished if the entire blockchain was recalculated. This functionality doesn't exist and furthermore, data falsification for transactions is prevented as well.


Ba Be National Park
Tranquil Ba Be National Park is absolutely stunning with the three interlinked Ba Be Lakes at its heart, rimmed by jagged karst peaks and thickly forested slopes.
Most visitors come here to take peaceful boat trips or kayak on the lake and explore the caves full of stalactites and stalagmites in the vicinity, but for the more active, there's also excellent hiking and trekking in the hills here between ethnic minority villages.
This is one of the most peaceful spots in Vietnam, and travelers who spend the night here sleep in traditional stilt-house homestay accommodation along the lakeshore, allowing an experience of simple rural life.

Variable Scope
5/17/15
The essence of flow and functionality lies in the hands of scope variability. The reason for this is because as code becomes more and more complicated it becomes equally more difficuly to figure out where a variables is accessible. In ruby there are four types of variables, local, global, instance, and class. These variables are designated by characters that come before the variables is created. Below is a figure that illuminates when and what to use for certain variables.
Local variables are declared within a method or a loop but cannot be accessed anywhere else outside the method. These local variables must have a lower case or Ruby will not assess the variable or read the variable correctly. Global variables, on the other hand, can be accessed anywhere in the ruby program. Global variables should be used with caution because as code becomes larger it becomes harder to also track where variables are first defined. This means that if one were to redefine the global variable somewhere else in the code, it would simultaneously introduce a bug and one would also have to track through all instances of the variable to change the definition.
A class variable is a variable that can be shared through all instances of a class. Using class variables solves the problem that would be introduced using global variables. Furthermore if one were to change the value of the variable, all other values associated with the variable will also change. Instance variables are inherently local to specific method making them very similar to class variables.


Comet parameter: num_output_lines
- This parameter controls the number of search result
hits (peptides) that are reported for each spectrum query.
- If you are only interested in seeing one top hit each
per query, set this value to 1.
- This parameter value cannot be larger than the value
entered for "num_results"
which itself is limited to a maximum value of 100.
- This parameter does not apply to the text output as
defined by "output_txtfile".
- Valid values are any positive integer 1 or greater.
- If a value less than 1 is entered, this parameter is set to 1.
- The default value is "10" if this parameter is missing.
Example:
num_output_lines = 1
num_output_lines = 5
num_output_lines = 10


Secretary of the Administrative Board John “Jay” L. Ellison said that the body has not searched a student email account in a case since he joined it in fall 2002 and likely will not in the future.
All three students were charged with violating the Faculty of Arts and Sciences’ rules on physical violence, FAS Dean Michael D. Smith announced at the monthly Faculty meeting on Tuesday.
Members of the Faculty of Arts and Sciences raised concerns about how frequently students would be required to make an affirmation of integrity under an updated proposal for the College’s first-ever honor code, which was presented by Dean of Undergraduate Education Jay Harris to the faculty at their monthly meeting Tuesday.
For the third consecutive year, 12 advisors at the College have been recognized by the Advising Programs Office for their outstanding guidance and mentorship in their work with undergraduates.
To address public confusion surrounding the Affordable Care Act and new applications of big data, the Harvard School of Public Health has developed two new courses slated to launch April 7 on HarvardX.
The Committee on Undergraduate Education continued its ongoing discussion about extending the pass/fail deadline later into the semester at its monthly meeting.
Faculty members will discuss a proposed student honor code, the passage of which would require students to make an affirmation of integrity, at their monthly meeting Tuesday.
Weston alleges that Harvard failed to comply with the terms of a 2010 contract which required the University to “remediate” contaminated portions of the 62.5-acre Case Estates property it had agreed to sell to the town.
The move comes just days after student leaders from the black and Latino communities came together to host a town hall to discuss race relations at Harvard.
The UC has formed a task force to involve students in the discussion on Harvard’s sexual assault policies in response to a first-person, anonymous op-ed published in The Crimson.


| MTH141 |
Math 141 or Calculus I is one of the requirements for the Computer Science and other
Enginning Majors. I took this time during an EOP summer program and it was pretty fun to have
that opportunity which it packs a regular college 15 weeks class schedule into 6 weeks. Overall,
pretty easy class to have as a freshman student. |
| MTH142 |
Math 142 or Calculus II is one of the requirements for the Computer Science
and other Enginning Majors. I took this class during 2016 fall semester. A pretty stander college
class with the regular class schedule. Although it is harder than Math 141, you can get a very high
score in this class if you do all of your work and definitely don't miss any lecture in this class.
Overall, a challenge but not impossible class. |
| CSE155 |
CSE115 or Introduction to Java is one of the requirements for the Computer Science.
I took this class during 2016 fall semester. A pretty challenge class if you have no java experience,
but once you complete every single lab and understand all concepts and the functionally of each component
you can get a very good score in this class without a problem. |
| CSE199 |
CSE199 or UB Seminar is one of the requirements for the Computer Science.
I took this class during 2016 fall semester. A pretty relax class that teach all concept about the Internet,
pretty good if you are new to the Internet. However, the grading on this class is very subjective
which the score on the video assignment is kind to depend on the person who's grading on it. Which I prefer
quiz and test rather let UTA grade the assignment. |
| ENG105 |
ENG105 or Writing and Rhetoric is one of the general requirements.
I took this class during 2016 fall semester. A stander English class as you wish to have in the college.
Only 5 to 7 essays with total length around 6000 words for the whole semester which it is pretty easy
if you compare to other 'writing class' history class.  A very nice guy. |

GEOIPUPDATE(1) GEOIPUPDATE(1) NAME geoipupdate - a program for updating the MaxMind GeoIP databases SYNOPSIS geoipupdate [-v] [-f licensefile] DESCRIPTION geoipupdate automatically updates the GeoIP database for GeoIP sub‐ scribers. It connects to the MaxMind GeoIP Update server and checks for an updated database. If it finds an updated database, then it downloads it, uncompresses it, and installs it. If you are running a firewall, it requires that the DNS and HTTP (80) ports be open. For example geoipupdate -v Performs the update in verbose mode. OPTIONS -v Verbose mode, prints out the steps that geoipupdate takes. -d Specify a custom directory target to install the GeoIP datafile(s). By default geoipupdate installs to /usr/share/GeoIP -f Specifies the configuration file that contains the license key. Defaults to /etc/GeoIP.conf USAGE Typically you'll want to write a weekly crontab that will run geoipup‐ date. Below is a sample crontab that runs geoipupdate on each Wednesday at noon: # top of crontab<EMAIL_ADDRESS>0 12 * * 3 BIN_DIR/geoipupdate # end of crontab To use with a proxy server, set the http_proxy environment variable. E.g. export http_proxy="http://proxy-hostname:port" RETURN CODES geoipupdate returns 0 on success, 1 on error. FILES /etc/GeoIP.conf Configuration file for GeoIP, should contain license key.

The Only Baidu SEO Checklist You Ever Need
by
Christian Schuster
Posted on September 22, 2020
Optimize your website content for the Baidu search engine in China with the following methods:
- Provide useful and up-to-date information
- Optimize your content for mobile devices (80% use)
- Research relevant keywords on Baidu Tongji and integrate them in your content
- Set plenty of internal links
- Add and receive many external links to and from high authority pages in Chinese 🡪 Tip: Baidu prefers links to and from China-based websites compared to foreign sites. Sites with Chinese content, a .cn domain and sites that are hosted in China or Hong Kong are preferred.
- Make sure your website loads fast since it has to go through the Great Firewall if it's hosted outside of China
- Fill out the meta description with around 78 simplified Chinese characters for Baidu
- Set up an intuitive and logical navigation and website structure, not too deep
- Add social signals 🡪 Tip: Baidu favors its own and related platforms like Baidu Zhidao, Baidu Baike, Baidu Tieba, and Zhihu
- Use static code instead of JavaScript and Flash since Baidu can't crawl these
- Index your site with the Baidu Webmaster Tool
- Make sure to comply with the censorship guidelines of the Chinese government
- Use Baidu Zhishu to analyze trends
- Consider Baidu PPC ads to boost your website and rankings - ideal for affordable Xiachen (target marketing to reach lower tiers in China)
- Feel free to hire a China SEO agency to help you with this

Apache™ FOP Design: Area Tree
Introduction
The Area Tree is an internal representation of the result document, representing pages and their contents. To make the concepts clearer and easier to understand, the code to implement the area tree matches the areas defined in the XSL-FO specification.
The area tree is created by the layout managers once the layout is decided for a page. Once a completed page is finished it can then be added to the area tree. From that point forward, the area tree model can then handle the new page. The data in the area tree must be minimal and independant. This means that the data uses less memory and can be serialized to an output stream if needed.
The Area Tree consists of a set of pages, which the actual implemenation places in a set of page sequences.
Structure
The area tree is a root element that has a list of page-viewport-areas. Each page viewport has a page-reference-area which holds the contents of the page. To handle the processing better FOP does not maintain a list at the root level but lets the area tree model handle each page as it is added.
Page
A page consists of a page+viewport pair.
The PageViewPort and Page with the regions is created by the LayoutMasterSet. The contents are then placed by the layout managers. Once the layout of a page is complete then it is added to the Area Tree.
Inside the page is a set of RegionViewport+Region pairs for each region on the page.
 These are before, start, body, end and after. Each region has a viewport and contains the areas produced from the children in the FO object heirarchy.
For the body area there are more subdivisions for before floats, footnotes and the main reference area. The main reference area is made from span areas which have normal flow reference areas as children. The flow areas are then created inside these normal flow reference areas.
 The layout manager then uses the page to add areas into the normal flow reference areas and floats and footnotes. After adding the areas for the body region then the other regions can be done layed out and added.
Block Areas
Block level areas contain either other blocks or line areas (which is a special block area).
A block is either positoned or stacked with other block areas.
Block areas are created and/or returned by all top level elements in the flow. The spacing between block areas is handled by an empty block area. A block area is stacked with other block areas in a particular direction, it has a size and it contains line areas made from a group of inline areas and/or block areas.
Line Areas
A line areas is simply a collection of inline areas that are stacked in the inline progression direction. A line area has a height and a start position. The line area is rendered by handling each inline area.
A line area gets a set of inline areas added until complete then it is justified and vertically alignedi when adding the areas. If the line area contains unresolved areas then there will be a line resolver that retains the justification information until all areas in the line are resolved.
Inline Areas
There are a few different types of inline areas. All inline areas have a height and width.
Unresolved areas can reserve some space to allow for possible sizes once it is resolved. Then the line can be re-justified and finalised.
Inline areas are stacked in a line area. Inline areas are objects such as character, viewport, inline-container, leader and space. A special inline area Word is also used for a group of consecutive characters.
The image and instream foreign object areas are placed inside a viewport. The leader (with use content) and unresolved page number areas are resolved to other inline areas.
Once a LineArea is filled with inline areas then the inline areas need to be aligned and adjusted to fill the line properly.
Repeated Areas
There are cases where the same subtree could be repeated in the area tree. These areas will be returned by the same layout managers. So it is possible to put a flag on the created areas so that the subtree data can be cached in the output. Examples of this are: static areas, table header/footer, svg.
Traits
A trait is information associated with an area. This could be information such as text colour or is-first.
Traits provide information about an area. The traits are derived from properties on the formatting object or are generated during the layout process. Many of the layout traits do not have actual values but can be derived from the Area Tree. Other traits that apply when rendering the areas are set on the area. Since setting the same value on every area would use a lot of memory then the traits are derived from default or parent values.
A dominant trait on a block area is set, for example font colour, so that every line area with the same dominant value can derive it. The text inline areas then get the font colour set on the inline area or from the line area or from the block area.
Classes
The following class structure will be used to represent the area tree.
Page Area Classes
The page area classes hold the top level layout of a page. The areas are created by the page master and should be ready to have flow areas added.
Block Area Classes
The block areas hold other block areas and/or line areas. The child areas are stacked in a particular direction.
Areas for tables, lists and block container have their child block areas stacked in different ways. These areas a placed with an absolute positioning. The absolute positioning is where the blocks are placed with an offset from the parent reference area.
Inline Area Classes
The inline areas are used to make up a line area. An inline area typically has a height, width and some content. The inline area is offset from the baseline of the current line area. The content of the inline area can be other inline areas or a simple atomic object.
Forward References
The Area Tree maintains a set of mappings from the reference to pages.
The PageViewPort holds the list of forward references that need resolving so that if a references is resolved during layout the page can be easily found and then fixed. Once all the forward references are resolved then the page is ready to be rendered.
To layout a page any areas that cannot be resolved need to reserve space. Once the inline area is resolved then the complete line should be adjusted to accomodate any change in space used by the area.
Caching
We may need to cache pages due to forward references or when keeping all pages.
This is done by serializing the Page. The PageViewport is retained to be used as a key for page references and backward references. The Page is serialized to an object stream and then all of the page contents are released. The Page is then recoved by reading from the object stream.
The PageViewport retains information about id areas for easy access.
Extensions
The Area Tree holds the Output Document extensions. This is information such as pdf bookmarks or other output document specific information that is not handled by XSL:FO.
It is also possible to create custom areas that extend a normal area. The actual data that is rendered could be set in a different way or depend on resolving a forward reference.
Area Tree Handlers
To handle different situations the handler for the Area Tree handles each page as it is added.
The RenderPagesModel sends the page directly to the renderer if the page is ready to be rendered. Once a page is rendered it is discarded. The StorePagesModel stores all the pages so that any page can be later accessed.
The Area Tree retains the concept of page sequences (this is not in the area tree in the spec) so that this information can be passed to the renderer. This is useful for setting the title and organising the groups of page sequences.

Tracking and Managing Your Postgres Connections
Managing connections in Postgres is a topic that seems to come up several times a week in conversations. I’ve written some about scaling your connections and the right approach when you truly need a high level of connections, which is to use a connection pooler like pgBouncer. But what do you do before that point and how can you better track what is going on with your connections in Postgres?
Postgres under the covers has a lot of metadata about both historical and current activity against a system. Within Postgres you can run the following query which will give you a few results:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
|
Each of these is useful in determining what you should do to better manage your connection count. All of these numbers can be useful to record every say 30 seconds and chart on your own internal monitoring. Lets break down each:
- active – This is currently running queries, in a sense this is truly how many connections you may require at a time
- idle – This is where you have opened a connection to the DB (most frameworks do this and maintain a pool of them), but nothing is happening. This is the one area that a connection pooler like pgBouncer can most help.
- idle in transaction – This is where your app has run a
BEGIN
but it’s now waiting somewhere in a transaction and not doing work.
For idle as mentioned above it’s one that you do want to monitor and if you see a high number here it’s worth investing in setting up a pgBouncer.
For idle in transaction this one is a bit more interesting. Here what you likely want to do when first investigating is get an idea of how old those are. You can do this by querying pg_stat_activity and filtering for where the state is idle in transaction
and checking how old those queries are. For ones that have been running too long you may want to manually kill them.
If you find that you have some stale transactions hanging around this could be for days, hours, or even just a few minutes you may want to set a default to kill those transactions.
To help with this Postgres has a nice feature of a statement_timeout
.  You can set this at both a global level and for a specific session. To do this at the database level you’d run this with an alter database dbnamehere set statement_timeout = 60000;
which is 60 seconds. To do so during a given session simply run set statment_timeout = 6000000;
.
For idle in transaction that have been running too long there is its own setting setting that you can set in a similar fashion idle_in_transaction_session_timeout
(on Postgres 9.6 and up). Setting both statement_timeout
and idle_in_transaction_session_timeout
will help with cancelling long running queries and transactions.
Keeping your connection limits in check should lead to a much healthier performing database and thus app.

file in the the source distribution.
The remainder of the instructions in this chapter assume the use of the binary GeoMesa HBase
distribution. If you have built from source, the distribution is created in the target
directory of
geomesa-hbase/geomesa-hbase-dist
.
More information about developing with GeoMesa may be found in the Developer Manual.
9.1.3. Configuration and Classpaths¶
GeoMesa HBase requires Hadoop and HBase jars and configuration files to be available on the classpath. This includes files such as the hbase-site.xml and core-site.xml files in addition to standard jars and libraries. Configuring the classpath is important if you plan to use the GeoMesa HBase command line tools to ingest and manage GeoMesa.
By default, GeoMesa HBase will attempt to read various HBase and Hadoop related environmental variables in order to
build the classpath. You can configure environment variables and classpath settings in
geomesa-hbase_2.11-$VERSION/conf/geomesa-env.sh
or in your external env (e.g. bashrc file). The logic GeoMesa
uses to determine which external entries to include on the classpath is:
1. If the environmental variables
GEOMESA_HADOOP_CLASSPATH
andGEOMESA_HBASE_CLASSPATH
are set then GeoMesa HBase will use these variables to set the classpath and skip all other logic.2. Next, if
$HBASE_HOME
and$HADOOP_HOME
are set then GeoMesa HBase will attempt to build the classpath by searching for jar files and configuration in standard locations. Note that this is very specific to the installation or distribution of Hadoop you are using and may not be reliable.3. If no environmental variables are set but the
hbase
andhadoop
commands are available then GeoMesa will interrogate them for their classpaths by running thehadoop classpath
andhbase classpath
commands. This method of classpath determination is slow due to the fact that thehbase classpath
command forks a new JVM. It is therefore recommended that you set manually set these variables in your environment or theconf/geomesa-env.sh
file.
In addition, geomesa-hbase
will pull any additional entries from the GEOMESA_EXTRA_CLASSPATHS
environment variable.
Note that the GEOMESA_EXTRA_CLASSPATHS
, GEOMESA_HADOOP_CLASSPATH
, and GEOMESA_HBASE_CLASSPATH
variables
all follow standard
Java Classpath conventions, which
generally means that entries must be directories, JAR, or zip files. Individual XML files will be ignored. For example,
to add a hbase-site.xml
or core-site.xml
file to the classpath you must either include a directory on the
classpath or add the file to a zip or JAR archive to be included on the classpath.
Use the geomesa classpath
command in order to see what JARs are being used.
A few suggested configurations are below:
When using EMR to install HBase or Hadoop there are AWS specific jars that need to be used (e.g. EMR FS). It is recommended to use EMR to install Hadoop and/or HBase in order to properly configure and install these dependencies (especially when using HBase on S3).
If you used EMR to install Hadoop and HBase, you can view their classpaths using the hadoop classpath
and
hbase classpath
commands to build an appropriate classpath to include jars and configuration files for
GeoMesa HBase:
export GEOMESA_HADOOP_CLASSPATH=$(hadoop classpath)
export GEOMESA_HBASE_CLASSPATH=$(hbase classpath)
export GEOMESA_HBASE_HOME=/opt/geomesa
export PATH="${PATH}:${GEOMESA_HBASE_HOME}/bin"
Configure GeoMesa to use pre-installed HBase and Hadoop distributions:
export HADOOP_HOME=/path/to/hadoop
export HBASE_HOME=/path/to/hbase
export GEOMESA_HBASE_HOME=/opt/geomesa
export PATH="${PATH}:${GEOMESA_HOME}/bin"
Configure the environment to use an HDP install
export HADOOP_HOME=/usr/hdp/current/hadoop-client/
export HBASE_HOME=/usr/hdp/current/hbase-client/
export GEOMESA_HBASE_HOME=/opt/geomesa
export PATH="${PATH}:${GEOMESA_HBASE_HOME}/bin"
If no HBase or Hadoop distribution is installed, try manually installing the JARs from maven:
export GEOMESA_HBASE_HOME=/opt/geomesa
export PATH="${PATH}:${GEOMESA_HBASE_HOME}/bin"
cd GEOMESA_HBASE_HOME
bin/install-hadoop.sh lib
bin/install-hbase.sh lib
You will also need to provide the hbase-site.xml file within a the GeoMesa conf
directory, an external
directory, zip, or JAR archive (an entry referencing the XML file directly will not work with the Java
classpath).
When creating a zip or jar file, the hbase-site.xml should be at the root level of the archive and not nested within any packages or subfolders. For example:
$ jar tf my.jar
META-INF/
META-INF/MANIFEST.MF
hbase-site.xml
# try this
cp /path/to/hbase-site.xml ${GEOMESA_HBASE_HOME}/conf/
# or this
cd /path/to/hbase-conf-dir
jar cvf conf.jar hbase-site.xml
export GEOMESA_EXTRA_CLASSPATHS=/path/to/confdir:/path/to/conf.zip:/path/to/conf.jar
Due to licensing restrictions, dependencies for shape file support must be separately installed. Do this with the following commands:
$ bin/install-jai.sh
$ bin/install-jline.sh
9.1.4. Deploying the GeoMesa HBase Distributed Runtime JAR¶
GeoMesa uses an HBase custom filter to improve processing of CQL queries. In order to use the custom filter, you must
deploy the distributed runtime jar to the HBase to the directory specified by the HBase configuration variable called
hbase.dynamic.jars.dir
. This is set to ${hbase.rootdir}/lib
by default. Copy the distribute runtime jar to
this directory as follows:
hadoop fs -put ${GEOMESA_HBASE_HOME}/dist/hbase/geomesa-hbase-distributed-runtime-$VERSION.jar ${hbase.dynamic.jars.dir}/
If running on top of Amazon S3, you will need to use the aws s3
command line tool.
aws s3 cp ${GEOMESA_HBASE_HOME}/dist/hbase/geomesa-hbase-distributed-runtime-$VERSION.jar s3://${hbase.dynamic.jars.dir}/
If required, you may disable distributed processing by setting the system property geomesa.hbase.remote.filtering
to false
. Note that this may have an adverse effect on performance.
9.1.5. Register the Coprocessors¶
GeoMesa utilizes server side processing to accelerate some queries. In order to utilize these features,
the GeoMesa coprocessor must be registered on all GeoMesa tables or registered site-wide and
the geomesa-hbase-distributed-runtime
code must be available on the classpath or at an
HDFS url, depending on the registration method used.
There are a number of ways to register the coprocessors, which are detailed later.
The following ways to register coprocessors can be done anytime and constitute the ‘upgrade path’, however, they may require HBase or tables to be taken offline.
- Register Site-Wide using the
hbase-site.xml
- Register Per-Table using the
hbase shell
The following ways to register coprocessors must be done before the tables are created.
- Classpath Auto-Registration
- System Property or geomesa-site.xml
- DataStore Param Registration
There are two ways to get the coprocessor code on the classpath.
- Modify the
hbase-env.sh
file and provide the path to thegeomesa-hbase-distributed-runtime
JAR in theHBASE_CLASSPATH
property. If this method is used, thegeomesa-hbase-distributed-runtime
JAR must be available at the given location on all master and region servers.- If registering the coprocessors on a per-table basis using the hbase shell, it is possible to provide the HDFS path to the
geomesa-hbase-distributed-runtime
JAR that was deployed in Deploying the GeoMesa HBase Distributed Runtime JAR.
The easiest method to register the coprocessors is to specify the coprocessors in the hbase-site.xml
.
To do this simply add the coprocessors classname to the hbase.coprocessor.user.region.classes
key.
<configuration>
<property>
<name>hbase.coprocessor.user.region.classes</name>
<value>org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor</value>
</property>
</configuration>
All new and existing non-system tables will have access to the GeoMesa Coprocessor.
If your hbase instance is used for more than GeoMesa table or would like to utilize HDFS to deploy the
geomesa-hbase-distributed-runtime
JAR or for some other reason do not wish to register the coprocessor
site wide you may configure the coprocessor on a per-table basis. This can be done by utilizing the the hbase shell
as shown below. When specifying a coprocessor, the coprocessor must be available on the HBase classpath on all
of the master and region servers or you must provide the HDFS URL for the geomesa-hbase-distributed-runtime
JAR that
was deployed in Deploying the GeoMesa HBase Distributed Runtime JAR.
To run the hbase shell simply execute:
$ ${HBASE_HOME}/bin/hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
hbase(main):001:0>
To get a list of the current tables run:
hbase(main):001:0> list
TABLE
geomesa
geomesa_QuickStart_id
geomesa_QuickStart_z2
geomesa_QuickStart_z3
4 row(s) in 0.1380 seconds
You will need to install the coprocessor on all table indexes list. The geomesa
table in this example is the metadata
table and does not need the coprocessor installed.
We use the alter
command to modify the configuration of the tables. The coprocessor
parameter in the alter
command may be modified to change the registration of the GeoMesa coprocessors.
'coprocessor'=>'HDFS_URL|org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor|PRIORITY|'
The ‘value’ of the coprocessor
parameter has four parts, separated by |
, two of which, HDFS_URL
and
PRIORITY
, are configurable depending on your environment.
- To provide the HDFS URL of the
geomesa-hbase-distributed-runtime
JAR replace HDFS_URL in the coprocessor value with the HDFS URL. This is only need if thegeomesa-hbase-distributed-runtime
JAR will not be on the classpath by other means.- To alter the priority (execution order) of the coprocessor change PRIRORITY to the desired value, this is optional and should be left blank if now used.
hbase(main):040:0> alter 'geomesa_QuickStart_id', METHOD => 'table_att', 'coprocessor'=>'|org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor||'
Updating all regions with the new schema...
22/22 regions updated.
Done.
0 row(s) in 5.0000 seconds
hbase(main):041:0> alter 'geomesa_QuickStart_z2', METHOD => 'table_att', 'coprocessor'=>'|org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor||'
Updating all regions with the new schema...
4/4 regions updated.
Done.
0 row(s) in 2.8850 seconds
hbase(main):042:0> alter 'geomesa_QuickStart_z3', METHOD => 'table_att', 'coprocessor'=>'|org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor||'
Updating all regions with the new schema...
4/4 regions updated.
Done.
0 row(s) in 2.9150 seconds
To verify this worked successfully, run:
hbase(main):002:0> describe 'TABLE_NAME'
Table TABLE_NAME is ENABLED
TABLE_NAME, {TABLE_ATTRIBUTES => {coprocessor$1 => '|org.locationtech.geomesa.hbase.coprocessor.GeoMesaCoprocessor||'}
COLUMN FAMILIES DESCRIPTION
{NAME => 'm', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_EN
CODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '655
36', REPLICATION_SCOPE => '0'}
1 row(s) in 0.1940 seconds
geomesa-hbase-distributed-runtime
JAR is available on the HBase classpath when the table is created then the
GeoMesa coprocessors will be automatically registered for that table.System Property or geomesa-site.xml are essentially the same as they utilize the same mechanism, but two different approaches.
If the Java system property geomesa.hbase.coprocessor.path
is set in the environment running the GeoMesa ingest
then the HDFS or S3 URL provided as the value will be automatically registered in the table descriptor. There are three
to do this.
- Set the system property in your shell environment using the
JAVA_TOOL_OPTIONS
environment variable.
export JAVA_TOOL_OPTIONS="${JAVA_TOOL_OPTIONS} -Dgeomesa.hbase.coprocessor.path=hdfs://path/to/geomesa-runtime.jar"
- Set the system property in the
geomesa-env.sh
script.
setvar CUSTOM_JAVA_OPTS "${JAVA_OPTS} -Dgeomesa.hbase.coprocessor.path=hdfs://path/to/geomesa-runtime.jar"
- Set the system property using the
geomesa-site.xml
configuration file.
<property>
<name>geomesa.hbase.coprocessor.path</name>
<value>hdfs://path/to/geomesa-runtime.jar</value>
<description>HDFS or local path to GeoMesa-HBase Coprocessor JAR. If a local path is provided it must be the same for
all region server. A path provided through the DataStore parameters will always override this property.
</description>
<final>false</final>
</property>
coprocessor.url
to set an HDFS or
S3 path to the geomesa-hbase-distributed-runtime
JAR.For more information on managing coprocessors see Coprocessor Introduction on Apache’s Blog.
9.1.6. Setting up the HBase Command Line Tools¶
Warning
To use HBase with the command line tools, you need to install the coprocessors first, as described above.
GeoMesa comes with a set of command line tools for managing HBase features located in
geomesa-hbase_2.11-$VERSION/bin/
of the binary distribution.
Note
You can configure environment variables and classpath settings in geomesa-hbase_2.11-$VERSION/bin/geomesa-env.sh.
If desired, you may use the included script bin/geomesa-hbase configure
to help set up the environment variables
used by the tools. Otherwise, you may invoke the geomesa-hbase
script using the fully-qualified path, and
use the default configuration.
The tools will read the $HBASE_HOME
and $HADOOP_HOME
environment variables to load the
appropriate JAR files for HBase and Hadoop. If installing on a system without HBase and/or Hadoop,
the install-hbase.sh
and install-hadoop.sh
scripts in the bin
directory may be used to download
the required HBase and Hadoop JARs into the lib
directory. You should edit this script to match the versions
used by your installation.
Note
See Logging Configuration for information about configuring the SLF4J implementation.
Note
GeoMesa provides the ability to provide additional jars on the classpath using the environmental variable
$GEOMESA_EXTRA_CLASSPATHS
. GeoMesa will prepend the contents of this environmental variable to the computed
classpath giving it highest precedence in the classpath. Users can provide directories of jar files or individual
files using a colon (:
) as a delimiter. These entries will also be added the the mapreduce libjars variable.
Use the geomesa-hbase classpath
command to print the final classpath that will be used when executing geomesa
commands.
The tools also need access to the hbase-site.xml
for your cluster. If $HBASE_HOME
is defined, it will pick
it up from there. However, it may not be available for map/reduce jobs. To ensure it’s availability,
add it at the root level of the geomesa-hbase-datastore
JAR in the lib folder:
$ zip -r lib/geomesa-hbase-datastore_2.11-$VERSION.jar hbase-site.xml
Warning
Ensure that the hbase-site.xml
is at the root (top) level of your JAR, otherwise it will not be picked up.
Due to licensing restrictions, certain dependencies for shape file support and faster XML parsing must be separately installed. Do this with the following commands:
$ bin/install-jai.sh
$ bin/install-jline.sh
$ bin/install-saxon.sh
Test the command that invokes the GeoMesa Tools:
$ bin/geomesa-hbase
INFO Usage: geomesa-hbase [command] [command options]
Commands:
...
For more details, see HBase Command-Line Tools.
9.1.7. Installing GeoMesa HBase in GeoServer¶
The HBase GeoServer plugin is bundled by default in a GeoMesa binary distribution. To install, extract
$GEOMESA_HBASE_HOME/dist/gs-plugins/geomesa-hbase-gs-plugin_2.11-$VERSION-install.tar.gz
into GeoServer’s
WEB-INF/lib
directory. Note that this plugin contains a shaded JAR with HBase 1.2.3
bundled. If you require a different version, modify the pom.xml
and build the GeoMesa HBase plugin project from
scratch with Maven.
This distribution does not include the Hadoop or Zookeeper JARs; the following JARs
should be copied from the lib
directory of your HBase or Hadoop installations into
GeoServer’s WEB-INF/lib
directory:
(Note the versions may vary depending on your installation.)
- hadoop-annotations-2.7.4.jar
- hadoop-auth-2.7.4.jar
- hadoop-common-2.7.4.jar
- hadoop-mapreduce-client-core-2.7.4.jar
- hadoop-yarn-api-2.7.4.jar
- hadoop-yarn-common-2.7.4.jar
- htrace-core-3.1.0-incubating.jar
- commons-cli-1.2.jar
- commons-io-2.5.jar (you may need to remove an older version (2.1) from geoserver)
- hbase-common-1.2.6.jar
- hbase-client-1.2.6.jar
- hbase-server-1.2.6.jar
- hbase-protocol-1.2.6.jar
- metrics-core-2.2.0.jar
- netty-3.6.2.Final.jar
- netty-all-4.0.41.Final.jar
- zookeeper-3.4.10.jar
- commons-configuration-1.6.jar
You can use the bundled $GEOMESA_HBASE_HOME/bin/install-hadoop.sh
script to install these JARs.
- hadoop-annotations.jar
- hadoop-auth.jar
- hadoop-common.jar
- protobuf-java.jar
- commons-io.jar
- hbase-server-1.2.6.jar
- zookeeper-3.4.10.jar
- commons-configuration-1.6.jar
The HBase data store requires the configuration file hbase-site.xml
to be on the classpath. This can
be accomplished by placing the file in geoserver/WEB-INF/classes
(you should make the directory if it
doesn’t exist). Utilizing a symbolic link will be use full here so any changes are reflected in GeoServer.
ln -s /path/to/hbase-site.xml /path/to/geoserver/WEB-INF/classes/hbase-site.xml
ln -s /usr/hdp/current/hbase-client/hbase-site.xml /path/to/geoserver/WEB-INF/classes/hbase-site.xml
Restart GeoServer after the JARs are installed.
<IP_ADDRESS>. Jackson Version¶
Warning
Some GeoMesa functions (in particular Arrow conversion) requires jackson-core-2.6.x
. Some versions
of GeoServer ship with an older version, jackson-core-2.5.0.jar
. After installing the GeoMesa
GeoServer plugin, be sure to delete the older JAR from GeoServer’s WEB-INF/lib
folder.
9.1.8. Connecting to External HBase Clusters Backed By S3¶
To use a EMR cluster to connect to an existing, external HBase Cluster first follow the above instructions to setup the new cluster and install GeoMesa.
The next step is to obtain the hbase-site.xml
for the external HBase Cluster, copy to the new EMR cluster and
copy it into ${GEOMESA_HBASE_HOME}/conf
. At this point you may run the geomesa-hbase command line tools.
If you wish to execute SQL queries using Spark, you must first zip the hbase-site.xml
file for the external cluster:
zip hbase-site.zip hbase-site.xml
Then copy the zip file to ${GEOMESA_HBASE_HOME}/conf
then add the zipped configuration file to the Spark classpath:
export SPARK_JARS=file:///opt/geomesa/dist/spark/geomesa-hbase-spark-runtime_2.11-${VERSION}.jar,file:///opt/geomesa/conf/hbase-site.zip
Then start up the Spark shell:
spark-shell --jars $SPARK_JARS
9.1.9. Configuring HBase on Azure HDInsight¶
HDInsight generally creates HBASE_HOME
in HDFS under the path /hbase
. In order to make the GeoMesa
coprocessors and filters available to the region servers, use the hadoop
filesystem command to put
the GeoMesa JAR there:
hadoop fs -mkdir /hbase/lib
hadoop fs -put geomesa-hbase-distributed-runtime-$VERSION.jar /hbase/lib/


To be able to receive events from the device management, a 3P service has to subscribe on the eventmgmt bundle (Internal eventing). The event type to use to receive the device management events is: EventTypes.DEVICE_MANAGEMENT_EVENT
You can refine the subscription by adding an LDAP filter string to receive events from a specific device.The LDAP filter could contain the property CSSEventConstants.EVENT_SOURCE that is equal to deviceId (the device Id is got from the IDevice service) and the property CSSEventConstants.EVENT_NAME that is equal to a constant in DeviceMgmtEventConstants class.
don't forget to import
org.societies.api.osgi.event.EventListener, org.societies.api.osgi.event.EventTypes, org.societies.api.osgi.event.CSSEventConstants, org.societies.api.css.devicemgmt.model.DeviceMgmtEventConstants

// -- Subscribe to Screen event
// Set filter
String screenEventFilter = "(&" +
"(" + CSSEventConstants.EVENT_NAME + "="+DeviceMgmtEventConstants.SCREEN_EVENT+")" +
")";
// Subscribe
eventManager.subscribeInternalEvent(this, new String[] {EventTypes.DEVICE_MANAGEMENT_EVENT}, screenEventFilter);
}

public IEventMgr getEventManager()
{
return eventManager;

public void setEventManager(IEventMgr eventManager)
{
if (null == eventManager) {
LOG.error("[COMM02] EventManager not available");
}
this.eventManager = eventManager;
}
@Override
public void handleInternalEvent(InternalEvent event) {

Watch | Man Rides JCB Tractor At 217 Km/h, Sets New Guinness World Record
The Guinness World Record website says that Martin initially broke the record by attaining a new record of 166.79 Km/h before going faster by reaching 217 km/h.
Earlier this year, for some bizarre reason, #JCBKiKhudai trended on Twitter in India and since then, the yellow machine has become people’s favourite meme on the Internet.
Well, JCB has hit the headlines once again and the reason is a little bizarre again. This time, a man drove a JCB tractor so fast that he ended up setting a new Guinness World Record.
Yes, lorry mechanic and motorcycle racer Guy Martin rode the JCB tractor at a whopping speed of 217 Km/h. The Guinness World Record website says that Martin initially broke the record by attaining a new record of 166.79 Km/h before going faster by reaching 217 km/h.
Well, seems Martin has a fascination for weird speed records as he currently holds records for the fastest speed on a gravity-powered snow sled (83.49 mph/134.368 kph), the fastest soapbox (85.61 mph/137.78 kph), and highest speed on a Wall of Death (78.15 mph/25.77 kph).
Martin used to be a truck mechanic before making a career in racing and then later on Television.
“There are some good folk there and they said about this idea of building the world’s fastest tractor. So I said ‘if you want it piloting give us a shout’ and that’s where it came about,” he told Guinness World Records.

The SCD Cloud is a service developed for use within Scientific Computing and the wider STFC for developing and supporting projects. SCD Cloud usage must comply with the Terms of Service. If you have any questions regarding the following, please contact<EMAIL_ADDRESS>By continuing to log in you accept the following Service Level for Virtual Machines (VMs):
- Support
- Technical Support for the SCD Cloud is offered during working hours.
- Tickets will be responded to within 2 working days.
- Support for the end-users of services hosted on the SCD Cloud is not provided, this includes but is not limited to using the Operating System.
- Availability
- We endeavour to minimize downtime of VMs however some is inevitable.
- Services built on the SCD Cloud where availability is important must be architected in such a way that they can tolerate VMs being unavailable.
- VMs are configured to update automatically although monthly reboots will be required.
- Storage
- The storage underlying the SCD Cloud is resilient for the purposes of availability of VMs.
- VMs on the SCD Cloud should not be used as a persistent Datastore.
- If you require more security for your data then arrange to back up your VMs.
- Maintenance
- We will endeavour to provide notification of scheduled downtimes of 2 working days.
- Regular maintenance will take place on Wednesday mornings between 10am and 12pm. The service should be considered at risk during this period.
- If a security patch requires it, you will normally be given 5 working days within which to reboot VMs, after which time a reboot will be forced.
- We reserve the right to reboot VMs without notice in order to preserve the integrity of the service.


Test purpose
- Create a Polyline entity and a Shape entity
- Use positions along the Polyline entity's path to generate a series of short lines, captured in the Shape entity's pathDefinition attribute
- The short lines should be calculated using the Seeded random number generator - c heck that the initial display is the same each time the page loads (this would not happen if we were using the Javascript Math.random() function)
Note that the Shape entity doesn't overlap the Polyline entity because it is positioned centrally and will often have different dimension values.
Touch test: should work as expected
