This short tutorial covers the installation instructions and a simple demonstration of the simulators capabilities.
Installation
Requirements
To compile and run TheSimulator, you will need
-
CMake 3.15 or later,
-
any compiler suite capabile of compiling C++17 with natural dependency paths (e.g. Visual Studio 17 or later, GCC 9.0 or later, LLVM Clang 9.0 or later, etc.),
-
python
(tested with both Python 2.7 and 3.6).
Furthermore,
-
if using Windows, have Python installed with its C headers,
-
if using Linux, have
python-all
(or at leastpython-distutils
andpython-dev
), -
if using Mac, have MacOS 10.15+ and Xcode 11.0+.
The following are also recommended
-
a text editor with XML and Python support,
-
Python 3.0 or later (note that if you use Python 3 you will need the
python3-*
equivalents of the abovementioned packages for Linux).
|
Note
|
TheSimulator already comes with embedded Python 3.0 support. However, this environment can only be invoked from the simulation binaries and is thus unlikely to be useful for prior testing. |
There are no external dependencies of the simulator itself, apart from pybind11
that is directly a submodule of its git repository (so don’t forget to clone with --recurse-submodules
or do git submodule init && git submodule update
if you forgot).
How to install TheSimulator on your machine
-
Clone the git repository into a new directory in your local filesystem. Throughout this tutorial, we will assume that the git repository has been cloned into a folder called
thesimulator
(so that the readme file can be found underthesimulator\README.md
) and that the cmake files together with the build outputs can be found underthesimulator\build
-
Enter the directory the repository has been cloned into
cd ./thesimulator
-
Make a new directory for the build outputs, separate from the source files for our convenience
mkdir build cd build
-
Execute the cmake configuration and generation steps
cmake ../
-
Upon successful
vcxprox
/makefile
generation, compile the simulator’s sourcescmake --build .
-
Search the build directory for the output executable (should be called
TheSimulator
but might depend on the compiler suite used). You can test it by invoking./TheSimulator --help
Steps 4 and 5 can alternatively be performed from CMake GUI.
A Crash Guide to simulation with TheSimulator
TheSimulator uses XML files for simulation configuration. The XML configuration file sets the simulation properties (i.e. how long the simulation should run for, what the output files are) and allows the addition of agents into the simulation environment. TheSimulator already comes with a small database of fairly versatile agents. Additional custom agents can then be added either by referencing their Python implementation or compiling their C++ implementation with the simulator itself.
The following is a configuration of our minimal example, Doob’s trader. The simulation environment for the Doob’s trader example consists of a price-time matched exchange, a trade logger that logs all occuring trades to the console output, a martingale market maker (in our particular case an symmetric instance of RandomWalkMarketMakerAgent
) and an a,b-Doob’s trader (a configured instance of a DoobAgent
) — a trader that only trades to profit from price upcrossings from a to b. The Doob’s Upcrossing Lemma then gives an upper bound on the expected total earnings of our trader by time n.

</Simulation>
Once the Simulation.xml
file is ready, we can run the simulation by calling
./TheSimulator Simulation.xml
on GNU-based systems, or
.\TheSimulator.exe Simulation.xml
on Windows.
Adding a custom agent
A custom C++ agent
It is easy to extend TheSimulator to add custom agents. If the new agents are to become a part of the simulator itself (in order to increase the execution speed), the following three steps should be followed
-
Create a new class, say
CustomAgent
, inheriting fromAgent
and implementing its virtual methods. Look into the sources ofDoobAgent
andBouchaudAgent
to see implementations of simple agents. -
Implement
receiveMessage
to handle the agent logic and interactions with the environemnt -
Add the following
else-if
clause to the methodSimulation::setupChildConfiguration
in the fileSimulation.cpp
for the simulator to recognize your agent in the input XML simulation configuration files.
else if (nodeName == "CustomAgent") {
auto eaptr = std::make_unique<CustomAgent>(this);
eaptr->configure(*nit, configurationPath);
m_agentList.push_back(std::move(eaptr));
}
Embedding a Python script is also pretty straightforward. See the official Python documentation on the topic for more information and examples.
Simple custom Python agent
Consider the following Python code
from thesimulator import *
class PrintingAgent:
def configure(self, params):
print(" --- Configuring with the following parameters --- ")
print(params)
print(" ------------------------------------------------- ")
def receiveMessage(self, simulation, type, payload):
currentTimestamp = simulation.currentTimestamp()
print("Received a message of type '%s' at time %d, payload %s " % (type, currentTimestamp, payload))
and the following simulation configuration
<Simulation start="0" duration="1001">
<PrintingAgent name="AGENT" parameter="value" />
</Simulation>
both located in the same directory (preferably the cwd
for the simulator to use the execution command below).
Upon running
./TheSimulator PrintingAgentExample.xml
you should see the following in the terminal output
ExchangeSimulator v2.0
- 'Simulation.xml' loaded successfully
- starting the simulations
--- Configuring with the following parameters ---
{'parameter': 'value'}
-------------------------------------------------
Received a message of type 'EVENT_SIMULATION_START' at time 0, payload {}
Received a message of type 'EVENT_SIMULATION_STOP' at time 1000, payload {}
- all simulations finished, exiting
Advanced custom Python agent
Consider the following Python sources for a simple system consisting of a pro-rata matched exchange, regular seller, and a greedy buyer that buys everything the seller offers at the exchange, regardless of the price.
from thesimulator import *
class SellingAgent:
def configure(self, params):
# save locally the configuration params passed so that they are properly typed
self.exchange = str(params['exchange'])
self.price = Money(float(params['price']))
self.quantity = int(params['quantity'])
self.interval = int(params['interval'])
def receiveMessage(self, simulation, type, payload):
# Firstly, ignore all messages that should not trigger selling (i.e. order placement confirmations, etc.)
if type != "EVENT_SIMULATION_START" and type != "WAKE_UP":
return
# Announce our intentions in the standard output
currentTimestamp = simulation.currentTimestamp()
print("%s: Selling %d units for %s, then going to sleep until %d" % (self.name(), self.quantity, self.price.toCentString(), currentTimestamp+self.interval))
# Schedule the (first/next) wakeup message `self.interval` time units later
simulation.dispatchGenericMessage(currentTimestamp, self.interval, self.name(), self.name(), "WAKE_UP", {})
# Place a limit order to buy `self.quantity` units of an instrument at the price `self.price`
limitOrderPayload = PlaceOrderLimitPayload(OrderDirection.Sell, self.quantity, self.price)
simulation.dispatchMessage(currentTimestamp, 0, self.name(), self.exchange, "PLACE_ORDER_LIMIT", limitOrderPayload)
from thesimulator import *
class BuyingAgent:
def configure(self, params):
# save locally the configuration params passed so that they are properly typed
self.exchange = str(params['exchange'])
self.quantity = int(params['quantity'])
def receiveMessage(self, simulation, type, payload):
currentTimestamp = simulation.currentTimestamp()
if type == "EVENT_SIMULATION_START":
# Subscribe to receive a message of type "EVENT_ORDER_LIMIT" whenever a limit order is submitted to the exchange `self.exchange`
simulation.dispatchMessage(currentTimestamp, 0, self.name(), self.exchange, "SUBSCRIBE_EVENT_ORDER_LIMIT", EmptyPayload())
return
elif type != "EVENT_ORDER_LIMIT":
# Ignore all messages that should not trigger buying (i.e. order placement confirmations, etc.
return
# Announce our intentions in the standard output
print("%s: Buying %d units, then going to sleep to wait for the next order to be submitted" % (self.name(), self.quantity))
# Place a limit order to buy `self.quantity` units of an instrument at the price `self.price`
marketOrderPayload = PlaceOrderMarketPayload(OrderDirection.Buy, self.quantity)
simulation.dispatchMessage(currentTimestamp, 0, self.name(), self.exchange, "PLACE_ORDER_MARKET", marketOrderPayload)
We shall use the following simulation configuration
<Simulation start="0" duration="1001">
<ExchangeAgent
name="EXCHANGE"
algorithm="PureProRata"
/>
<SellingAgent
name="AGENT_SELLER"
exchange="EXCHANGE"
price="22.75"
quantity="100"
interval="200"
/>
<BuyingAgent
name="AGENT_BUYER"
exchange="EXCHANGE"
quantity="100"
/>
<TradeLogAgent
name="LOGGER_TRADES"
exchange="EXCHANGE"
/>
</Simulation>
with both sources and the configuration file located in the same directory (preferably the cwd
for the simulator to use the execution command below).
Upon running
./TheSimulator SellerBuyerExample.xml
you should see the following in the terminal output
ExchangeSimulator v2.0
- 'Simulation.xml' loaded successfully
- starting the simulations
AGENT_SELLER: Selling 100 units for 22.75, then going to sleep until 200

About Me
I enrolled in University Of Adelaide coding bootcamp, not to change career or get a job, but to learn web full stack development as part of a skill required by my startup company to
design and develop an IoT tracking product for a particular market segment. I could employ a developer but, since the coding bootcamp is a fast-track 26-week course, I decided to learn
the skill myself. I have always been keenly interested in web design including full stack web development and the new technologies that go with it. Upon completion, I will probably do some freelance work as I
and have six paying clients already waiting! Also, I have a good graphic designer, who can create visual impact and visual flow, to partner with.
My professional background is engineering (biomedical and rehabilitation)
with graduate business studies (Innovation and Entrepreneurship). The business studies taught me that, to be successful in business, it is essential to learn marketing to understand human behavior and how to persuade!
And isn't social media (digital marketing) a great medium for persuasion!
In recent years, I have diversified into establishing and managing (with my wife) a successful business of local manufacture and supplier
of corporate uniform to a national airline! The business currently has no website landing page... but it will soon once I have learned how to design one!!

How to lose a guy in 10 weeks
Advice and tales from students who got ditched (and hitched) abroad.
By David Gleisner
When Abby left for Sydney, Australia at the beginning of winter quarter last year, she had a lot on her mind: her new living situation, the classes she’d be taking, the new people she’d meet. One thing that she was not focused on was Jonathan, her ex-boyfriend. They had split up several months earlier at the end of the summer and had avoided each other all fall quarter.
But Jonathan was thinking about her. And he was doing so on the steps of the Sydney Opera House, wearing a full suit and holding a light blue Tiffany bag.
Abby knew he would be traveling to Australia, but after a long flight, orientation, dinner and drinks, she did not expect – or want – to see him on her first day there.
“I had been awake for like 48 hours straight, and I was slightly buzzed. I was just dead, and then he starts texting me,” Abby recalls. “He was like, ‘I’ve been at the Opera House for six hours.’”
Abby was shocked, but she agreed to meet Jonathan for drinks because she felt bad for the man who had waited in the blazing sun for her.
“Of all the people I expect to spend my night with on my first day in Australia,” Abby says, “it is not my ex-boyfriend.”
For many students, study abroad is a time for new beginnings, a time to “find yourself” and, more importantly, gather stories with which to annoy your friends when you get back. In this valiant quest, relationships from back home can seem like a drag, and many students cut them out.
But starting fresh isn’t always as easy as it seems. Abby and Jonathan started dating their first year at Northwestern, and after their breakup before junior year, they avoided each other completely. While she was home for winter break, though, Abby received an “uncomfortably long” text from her ex detailing his plans to travel to Australia, coincidentally, around the same time she would be there.
“I was just floored,” Abby says. “We hadn’t talked at all. That’s what made it so strange — we just averted eye contact for three straight months at school.”
In Australia, after going out for drinks, Jonathan gave Abby the Tiffany bag, which held a diamond necklace and a 13-page handwritten confession of Jonathan’s feelings.
“I felt really kind of pity, because I was like, ‘I cannot believe you embarrassed yourself so much,’” Abby says.
The two got together a few times for coffee or drinks as Abby grappled with trying to form a friendship with her ex. But eventually, Abby realized she would have to tell him the truth.
“I realized that I really am gonna have to explain to him that this is not gonna happen,” Abby says. “And I think he slowly admitted to me that a big reason why he came there was not for himself, it was because he knew I was gonna be there. Shocking.”
Cutting off his relationship before studying abroad was also a priority for Will, who relocated to France last September. Will and Jessica began dating following a chance encounter at a Willard formal late fall quarter in 2016, just as Will was finishing up his application to study at Sciences Politiques in Paris. Will planned to study abroad for a full year, and he knew the relationship wouldn’t last. He decided to cut it off at the end of spring quarter.
“I was like, ‘I think there’s something special here so I don’t want to just take off, but I’m gonna just take off,’” Will says. “We did a very bad job breaking up. We broke up in name only mostly.”
The two continued talking throughout the summer despite living in different parts of the country, and when Will left for France, they were still FaceTiming on a weekly basis. As Will settled into Parisian life, he wasn’t having nearly as good of a time as he anticipated. While he toured the apartment he would be living in for the spring semester, he thought about having to continue living apart from Jessica, and had a realization.
“It was like this terrifying deer in headlights moment,” Will says, “And I was like, ‘Fuck, I can’t do this, I have to go back.’” Upending his plans, Will flew back to Chicago to begin winter quarter at Northwestern. He and Jessica got back together, and winter quarter was “awesome, it was great.” But then Jessica headed off to Israel for a spring break trip, marking the beginning of the end for their relationship.
“She came back from the spring break trip to Israel,” Will says.
Will did not anticipate this breakup round two. In retrospect, he sees how going abroad can have different effects on different people. For some, it causes a months long desire, and for others, it causes them to rethink what and who is important in their lives.
Although the excitement for exploring a new country can mean the end of relationships at home, cuffing season happens abroad, too. In the second act of Abby’s soap opera, just as her ex-boyfriend was preparing to head back to the U.S., she ventured into Tinder for the first time in her life. The dating app led to a beach date with an Australian man, Matthew, which led to many more dates. She and Matthew went on a trip to Japan together before Abby headed back home to New Jersey for the summer. She knew she wanted to keep the relationship going and hoped to see him again at some point, and this guy pulled through.
“[He] came a little less than a month after I left,” Abby says. “So I have this 25-year-old Australian man flying to New Jersey to stay with my parents and my sister and I.” Matthew, who had just quit his job at a non-profit, flew halfway around the world to visit. Their fairytale romance, however, just wasn’t the same in New Jersey as it was in Australia, Abby says. The day after he left, she gave him a call letting him know they needed to break up.
When there isn’t an ocean separating a couple, going abroad can be the perfect catalyst for a happy, healthy relationship. Catherine and Peter got to know each other patrolling the beaches of Costa Rica on a Global Engagement Studies Institute (GESI) summer program. Neither knew of the other’s growing feelings, but on a trip to a volcano at the end of their program, things became clearer. The cold climate of the high elevation led to cozy cuddling, and friendly hand-holding led to kisses. When they arrived back home after the program ended and continued talking, Catherine knew it was something special.
“I started thinking about it after the volcano,” Catherine says. “We were apart until school started, and we would talk all the time, and I was like, ‘This is something I’m actually feeling.’”
Their relationship blossomed when they got back to campus. The couple is now trying out Northwestern life, which Catherine says is “really good, zero complaints.” Growing close abroad gave the two an idea of what it’s like to relax together, and back in the hectic life of NU, Catherine says that understanding is invaluable.
“I don’t want to say we change as people abroad versus being here in the U.S. and working and being students, but our goals and things are just completely different once we come back to Northwestern,” Catherine says. “We’re just making new memories.”

POL60700: Democratic Innovations in the Digital Age
Seminar 7
München/Zoom, 1. June 2021
Nikolai Gad
This week: New possibilities for democratic innovations with digital technologies?
Next week: New challenges for democratic innovations with digital technologies?
Digital Democratic Innovations (or Civic tech)
Is there a special "type" of digital democratic innovations?
Or a special type of digital technology for democratic innovation?
Gilman & Peixoto's definition of "civic tech":
"A technology that is explicitly designed and leveraged to increase and deepen democratic participation."
Group work
Democratic goods of digital technologies in democratic innovations?
Main take-aways from this week
- Digital technologies can be used in many different ways in the design of democratic innovaitons.
- There are both potentials and challenges related to this.
- There are several challenges in studying digital technologies in relation to democratic innovations:
- How to isolate the effect of the "digital", since digital technologies often are combined with institutional changes.
- How do we define or characterise the "digital" element? Digital technologies can take many forms.

HTTP Storage Plugin
Introduced in release: 1.18
The HTTP storage plugin lets you query APIs over HTTP/REST. The plugin expects JSON or CSV responses.
The HTTP plugin is new in Drill 1.18 and is an Alpha feature. It works well, and we enourage you to use it and provide feedback. However, we reserve the right to change the plugin based on that feedback.
Configuration
To configure the plugin, create a new storage plugin and add the following configuration options which apply to all of the connections defined in this plugin:
{
"type": "http",
"cacheResults": true,
"connections": {},
"timeout": 0,
"proxyHost": null,
"proxyPort": 0,
"proxyType": null,
"proxyUsername": null,
"proxyPassword": null,
"enabled": true
}
Configuration Options
| Option | Default | Description |
|---|---|---|
| type | (none) | Set to “http” to use this plugin |
| cacheResults | false | Enables local caching of received HTTP response data |
| timeout | 0 | HTTP request timeout in seconds, 0 = no timeout |
| connections | (none) | This field contains the details for individual connections. See the section Configuring API Connections for Details |
You can configure the HTTP storage plugin to work through an HTTP proxy. Details are listed below.
Configuring the API Connections
The HTTP Storage plugin allows you to configure multiple APIS which you can query directly from this plugin. To do so, first add a connections
parameter to the configuration. Next give the connection a name, which will be used in queries. For instance stockAPI
or jira
.
The connection
property can accept the following options.
URL
url
: The base URL which Drill will query.
requireTail
: Set to true
if the query must contain an additional part of the service
URL as a table name, false
if the URL needs no additional suffix other than that
provided by WHERE
clause filters. (See below.)
If your service requires parameters, you have three choices. Suppose your connection is called
sunrise
. First, can include them directly in your URL if the parameters a fixed for a given
service:
{
"url": "https://api.sunrise-sunset.org/json?lat=36.7201600&lng=-4.4203400&date=2019-10-02",
"requireTail": false
}
Query your table like this:
SELECT * FROM api.sunrise;
Second, you can specify the base URL here and the full URL in your query. Use this form if the parameters define a table-like concept (the set of data to return):
{
"url": "https://api.sunrise-sunset.org/json",
"requireTail": true
}
SQL query:
SELECT *
FROM api.sunrise.`?lat=36.7201600&lng=-4.4203400&date=2019-10-02`
If the URL requires a tail, specify it as if it were a table name. (See example below.) Drill directly appends the “tail” to the base URL to create the final URL.
Third, you can use the params
field below to specify the parameters as filters
if the parameters specify which data sets to return:
{
"url": "https://api.sunrise-sunset.org/json",
"requireTail": false,
"params": ["lat", "lng", "date"]
}
SQL query:
SELECT *
FROM api.sunrise
WHERE `lat` = 36.7201600
AND `lng` = -4.4203400
AND `date` = '2019-10-02'
In this case, Drill appends the parameters to the URL, adding a question mark to separate the two.
Method
method
: The request method. Must be GET
or POST
. Other methods are not allowed and will default to GET
.
postBody
: Contains data, in the form of key value pairs, which are sent during a POST
request. The post body should be in the of a block of text with key/value pairs:
{
"postBody": "key1=value1
key2=value2"
}
Headers
headers
: Often APIs will require custom headers as part of the authentication. This field allows
you to define key/value pairs which are submitted with the http request. The format is:
"headers": {
"key1": "Value1",
"key2": "Value2"
}
Query Parmeters as Filters
params
: Allows you to map SQLWHERE
clause conditions to query parameters.
{
"url": "https://api.sunrise-sunset.org/json",
"params": ["lat", "lng", "date"]
}
SQL query:
SELECT * FROM api.sunrise
WHERE `lat` = 36.7201600 AND `lng` = -4.4203400 AND `date` = '2019-10-02'
HTTP parameters are untyped; Drill converts any value you provide into a string.
Drill allows you to use any data type which can convert unambiguously to a string:
BIT
, INT
, BIGINT
, FLOAT4
, FLOAT8
, VARDECIMAL
, VARCHAR
. The BIT
type
is translated to true
and false
. Note that none of the date or interval types
are allowed: each of those requires formatting.
Note the need for back-tick quotes around the names;
date
is a reserved word. Notice also that the date is a string because of
the formatting limitation mentioned above.
Only equality conditions can be translated to parameters. The above filters are translated to:
lat=36.7201600&lng=-4.4203400&date=2019-10-02
If your query contains other conditions (!=
, <
, etc.) then those conditions are applied
in Drill after the REST service returns the data.
Only fields listed in the params
config filed will become parameters, all other
experssions are handled within Drill as explained above.
At present, Drill requires the values to be literals (constants). Drill does not currently allow expressions. That is, the following will not become an HTTP parameter:
WHERE `lat` = 36 + 0.7201600
Drill will add parameters to the URL in the order listed in the config. Use this feature if the API is strict about parameter ordering.
At present Drill does not enforce that parameters are provided in the query: Drill assumes parameters are optional.
Data Path
REST responses often have structure beyond the data you want to query. For example:
{
"results":
{
"sunrise":"7:27:02 AM",
"sunset":"5:05:55 PM",
"solar_noon":"12:16:28 PM",
"day_length":"9:38:53",
"civil_twilight_begin":"6:58:14 AM",
"civil_twilight_end":"5:34:43 PM",
"nautical_twilight_begin":"6:25:47 AM",
"nautical_twilight_end":"6:07:10 PM",
"astronomical_twilight_begin":"5:54:14 AM",
"astronomical_twilight_end":"6:38:43 PM"
},
"status":"OK"
}
Drill can handle JSON structures such as the above; you can use SQL to obtain the
results you want. However, the SQL will be simpler if we skip over the portions we
don’t want and simply read the results
fields as our SQL fields. We do that with
the dataPath
configuration:
"dataPath": "results"
The dataPath
can contain any number of fields, for example: "response/content/data"
.
Drill will ignore all JSON content outside of the data path.
At present, there is no provision to check the status
code in a response such
as that shown above. Drill assumes that the server will uses HTTP status codes to
indicate a bad request or other error.
Input Type
The REST plugin accepts three different types of input: json
, csv
and xml
. The default is
json
. If you are using XML
as a data type, there is an additional configuration option called
xmlDataLevel
which reduces the level of unneeded nesting found in XML files. You can find more
information in the documentation for Drill’s XML format plugin.
Authorization
authType
: If your API requires authentication, specify the authentication
type. At the time of implementation, the plugin only supports basic authentication, however, the
plugin will likely support OAUTH2 in the future. Defaults to none
.
If the authType
is set to basic
, username
and password
must be set in the configuration as well.
username
: The username for basic authentication.
password
: The password for basic authentication.
Usage
This plugin is different from other plugins in that it the table component of the FROM
clause
is different. In normal Drill queries, the FROM
clause is constructed as follows:
FROM <storage plugin>.<schema>.<table>
For example, you might have:
FROM dfs.test.`somefile.csv`
-- or
FROM mongo.stats.sales_data
The HTTP/REST plugin the FROM
clause enables you to pass arguments to your REST call if you
set the requireTail
property to true
. The structure is:
FROM <plugin>.<connection>.<arguments>
--Actual example:
FROM http.sunrise.`/json?lat=36.7201600&lng=-4.4203400&date=today`
Or, as explained above, you can have the URL act like a table and pass parameters
using a WHERE
clause “filter” conditions.
Proxy Setup
Some users access HTTP services from behind a proxy firewall. Drill provides three ways specify proxy configuration.
Proxy Environment Variables
Drill recognizes the usual Linux proxy environment variables:
http_proxy
,HTTP_PROXY
https_proxy
,HTTP_PROXY
all_proxy
,ALL_PROXY
This technique works well if your system is already configured to handle proxies.
Boot Configuration
You can also specify proxy configuration in the drill-override.conf
file.
See drill-override-example.conf
for a template. Use the boot configuration
is an attribute of your network environment. Doing so will ensure every
Drillbit and every HTTP/HTTPS request uses the same proxy configuration.
First, you can use the same form of URL you would use with the environment variables:
drill.exec.net_proxy.http_url: "http://foo.com/1234"
There is one setting for HTTP, another for HTTPS.
Alternatively, you can specify each field separately:
drill.exec.net_proxy.http: {
type: "none", # none, http, socks. Blank same as none.
host: "",
port: 80,
user_name: "",
password: ""
},
The valid proxy types are none
, http
and socks
. Blank is the same
as none
.
Again, there is a parallel section for HTTPS.
In the HTTP Storage Plugin Config
The final way to configure proxy is in the HTTP storage plugin itself. The proxy applies to all connections defined in that plugin. Use this approach if the proxy applies only to some external services, or if each service has a different proxy (defined by creating a separate plugin config for each service.)
{
"proxy_type": "direct",
"proxy_host": "",
"proxy_port": 80,
"proxy_user_name": "",
"proxy_password": ""
}
The valid proxy types are direct
, http
or socks
. Blank is the same
as direct
.
Examples
Example 1: Reference Data, A Sunrise/Sunset API
The API sunrise-sunset.org returns data in the following format:
"results":
{
"sunrise":"7:27:02 AM",
"sunset":"5:05:55 PM",
"solar_noon":"12:16:28 PM",
"day_length":"9:38:53",
"civil_twilight_begin":"6:58:14 AM",
"civil_twilight_end":"5:34:43 PM",
"nautical_twilight_begin":"6:25:47 AM",
"nautical_twilight_end":"6:07:10 PM",
"astronomical_twilight_begin":"5:54:14 AM",
"astronomical_twilight_end":"6:38:43 PM"
},
"status":"OK"
}
To query this API, set the configuration as follows:
{
"type": "http",
"cacheResults": false,
"enabled": true,
"timeout": 5,
"connections": {
"sunrise": {
"url": "https://api.sunrise-sunset.org/json",
"requireTail": true,
"method": "GET",
"headers": null,
"authType": "none",
"userName": null,
"password": null,
"postBody": null,
"inputType": "json"
}
}
Then, to execute a query:
SELECT api_results.results.sunrise AS sunrise,
api_results.results.sunset AS sunset
FROM http.sunrise.`?lat=36.7201600&lng=-4.4203400&date=today` AS api_results;
Which yields the following results:
|------------|------------|
| sunrise | sunset |
|------------|------------|
| 7:17:46 AM | 5:01:33 PM |
|------------|------------|
1 row selected (0.632 seconds)
Using Parameters
We can improvide the above configuration to use WHERE
clause filters and
a dataPath
to skip over the unwanted parts of the message
body. Set the configuration as follows:
{
"type": "http",
"cacheResults": false,
"enabled": true,
"timeout": 5,
"connections": {
"sunrise": {
"url": "https://api.sunrise-sunset.org/json",
"requireTail": false,
"method": "GET",
"dataPath": "results",
"headers": null,
"params": [ "lat", "lng", "date" ],
"authType": "none",
"userName": null,
"password": null,
"postBody": null
}
}
Then, to execute a query:
SELECT sunrise, sunset
FROM http.sunrise
WHERE `lat` = 36.7201600 AND `lng` = -4.4203400 AND `date` = 'today'
Which yields the same results as before.
Example 2: JIRA
JIRA Cloud has a REST API which is documented here.
To connect Drill to JIRA Cloud, use the following configuration:
{
"type": "http",
"cacheResults": false,
"timeout": 5,
"connections": {
"jira": {
"url": "https://<project>.atlassian.net/rest/api/3/",
"method": "GET",
"dataPath": "issues",
"headers": {
"Accept": "application/json"
},
"authType": "basic",
"userName": "<username>",
"password": "<API Key>",
"postBody": null
}
},
"enabled": true
}
Once you’ve configured Drill to query the API, you can now easily access any of your data in JIRA. The JIRA API returns highly nested data, however with a little preparation, it is pretty straightforward to transform it into a more useful table. For instance, the query below:
SELECT key,
t.fields.issueType.name AS issueType,
SUBSTR(t.fields.created, 1, 10) AS created,
SUBSTR(t.fields.updated, 1, 10) AS updated,
t.fields.assignee.displayName as assignee,
t.fields.creator.displayName as creator,
t.fields.summary AS summary,
t.fields.status.name AS currentStatus,
t.fields.priority.name AS priority,
t.fields.labels AS labels,
t.fields.subtasks AS subtasks
FROM http.jira.`search?jql=project%20%3D%20<project>&&maxResults=100 AS t`
The query below counts the number of issues by priority:
SELECT t.fields.priority.name AS priority,
COUNT(*) AS issue_count
FROM http.jira.`search?jql=project%20%3D%20<project>&&maxResults=100` AS t
GROUP BY priority
ORDER BY issue_count DESC
Limitations
-
The plugin is supposed to follow redirects, however if you are using authentication, you may encounter errors or empty responses if you are counting on the endpoint for redirection.
-
At this time, the plugin does not support any authentication other than basic authentication.
-
This plugin does not implement join filter pushdowns (only constant plushdowns are supported). Join pushdown has the potential to improve performance if you use the HTTP service joined to another table.
-
This plugin only reads JSON, CSV and XML response data.
-
POST
bodies can only be in the format of key/value pairs. Some APIs accept JSON basedPOST
bodies but this is not currently supported. -
When using
dataPath
, the returned message should a single JSON object. The field pointed to by thedataPath
should contain a single JSON object or an array of objects. -
When not using
dataPath
, the response should be a single JSON object, an array of JSON objects, or a series of line-delimited JSON objects (the so-called jsonlines format.) -
Parameters are considered optional; no error will be given if a query omits parameters. An enhancement would be to mark parameters as required: all are required or just some. If parameters are required, but omitted, the report service will likely return an error.
Troubleshooting
If anything goes wrong, Drill will provide a detailed error message, including URL:
DATA_READ ERROR: Failed to read the HTTP response body
Error message: Read timed out
Connection: sunrise
Plugin: api
URL: https://api.sunrise-sunset.org/json?lat=36.7201600&lng=-4.4203400&date=today
Fragment: 0:0
If using a “tail” in the query, verify that the tail is quoted using back-ticks as shown in the examples.
Check that the URL is correct. If not, check the plugin configuration properties described above to find out why the pieces were assembed as you want.
If the query works but delivers unexpected results, check the Drill log file. Drill logs a message like the following at the info level when opening the HTTP connection:
Connection: sunrise, Method: GET,
URL: https://api.sunrise-sunset.org/json?lat=36.7201600&lng=-4.4203400&date=today
If the query runs, but produces odd results, try a simple SELECT *
query. This may reveal
if there is unexpected message context in addition to the data. Use the dataPath
property
to ignore the extra content.


[gecode-users] unsigned 32bit representation, additions
Christian Schulte

Hi Serg,
For the time being there is not much that you can do about this. And Gecode cannot be easily recompiled using unsigned ints (or 64 bit integers for that matter). I think some people have been experimenting with arbitrary precision integers as well as bit vectors but I do not know how far that got. Anybody?
Best

Subject: [gecode-users] unsigned 32bit representation, additions
Hi Group,
I'm thinking about the ways of implementing 32bit unsigned integer representations in gecode model.
So I have 32 BoolVar's per uint32 representation, which are used to store corresponding bits, then I can easily define bitwise operations on "integers" by posting relation constraints on the bits.
The problem is with the addition.
My first approach was to add an IntVar, post linear constraints with powers of 2 as coefficients to reconstruct integer from bits, however gecode limits IntVar into signed int bounds and it doesn't fit.
The second approach was to just implement binary addition:
bool lsb = true;
for (int i=(INT_BITS-1); i>=0; i--) {
BoolVarArgs bits;
bits << bools[i] << x->bools[i];
if (!lsb) {
bits << result->bools[INT_BITS+i+1];
}
rel(*model, BOT_XOR, bits, result->bools[i]);
if (lsb) {
rel(*model, BOT_AND, bits, result->bools[INT_BITS+i]);
lsb = false;
} else {
linear(*model, bits, IRT_GQ, 2, result->bools[INT_BITS+i]);
}
}
(bools[i] - bits of the first "integer", x->bools[i] - bits of the second "integer", result->bools[i] - bits of the resulting "integer", result->bools[INT_BITS+i] - carry bits)
That works but it turned out to be very inefficient in practice, complexity of the model is growing exponentially with this approach.
Any thoughts? Maybe there's a way to recompile gecode to use unsigned int internally? Maybe there are ideas on better implementation of addition? Maybe just some suggestion on another tool which uses unsigned ints internally?
Thanks,
Serg

Residents 'sceptical' about plans to move parking on chaotic road
by Sophie BarnettA congested road in Hadleigh which has long been a contentious subject in the town could finally have a solution - as plans to move parking spaces are put forward.
Benton Street has caused a variety of problems for residents and passers-by in Hadleigh, with complaints of overweight lorries using it to reach industrial estates and drivers mounting the pavements going back years.
Residents have had their parked cars damaged, with wing-mirrors being knocked off and cars being scraped, as well as homes getting damaged.
Read more: Meet the woman fighting for her street after 25% of residents report being hit by cars
Yesterday, a van smashed into a parked car resulting in it being written off and its owner being forced to take time off work.
Meanwhile, Rosie Stamp, who grew up in Suffolk and moved to Benton Street last year, also had her parked car written off due to someone hitting it.
She said: "The street was designed for horse and carts - not the type of traffic we have now.
"When I go outside to get in the car each morning I'm always half expecting to see some type of new dent or scratch. Cars also regularly mount the pavement at speed, so I am always cautious when walking down the road."
The 29-year-old says the road needs to be made one-way and doesn't see any other solution.
She said: "This will prevent cars trying to squeeze past each other and mounting the pavement, or hitting houses. There also needs to be enforcement to prevent lorries coming down the road, such as a camera."
What's being done?
Mick Fraser, Suffolk county councillor for Hadleigh, said the council's priority was the safety of pedestrians, as too many cars have been driving along pavements.
He said: "The key problem is that Benton Street is narrow in places and there is inconsiderate parking."
Suffolk Highways designed a number of possible solutions which were put forward to Hadleigh residents earlier this year, with Mr Fraser stating that "some options were realistic, while others were controversial".
Results showed that the residents' preferred option was a diversion via Hook Lane representing 34.31%, and the second most favoured was to install a one-way system along Benton Street in a North direction, which accounted for 21.17%.
While the relocation of on-street parking and a possibility to provide new off-street parking received 13.4% support.
This relocation of parking spaces to wider areas of the street is the option Suffolk Highways are going to proceed with. It will be considered by Hadleigh Town Council this month and could be implemented next year.
Mr Fraser said: "If it is agreed the relocation of parking spaces would coincide with several parking enforcements, allowing the district council to deploy traffic wardens in the town.
"This means some residents would need to find somewhere else to park."
According to Mr Fraser, Hadleigh United FC has offered its car park to residents for a monthly fee.
Mr Fraser says he hopes that the plan will help resolve the problem, if it is agreed.
However, not everyone is optimistic about the decision to relocate on-street parking spaces.
'I'm sceptical about the plans'
Emma Heath, 40, who lives in Benton Street, was devastated after her home was hit by a double decker bus in December last year - causing severe structural damage which is yet to be fixed.
Emma, whose property has been hit more than four times over the last 12 months, admits that she "lives on edge" and would sell the property if she could.
When asked about the proposal to relocate spaces, Emma says she is "sceptical" but would "like to see something put in place".
She said: "It's been really frustrating because people keep talking about the problem but nothing happens.
"The traffic is only going to get worse. I don't see how moving parking spaces will make much difference, a short-term solution would be to enforce the rules already in place - such as stopping lorries with cameras and traffic wardens, but personally I think making the road one-way is the best option."
What do you think needs to be done? Get in touch here.


Did you ever think of something you wanna do and when you come to it its kind of totally diffrent than what u ever expected but to the good its actually better than what you thought of yeah thats what i got when i came to programing, and thats what keeps want me to really move on and not to loose hope and get inspered on programing, in every moment a joyce exist we can claim 2 the past or embrace the enevetability of change and allow a better future to unfold before us , basically thats mostly about what we are doing programing is all about looking on whats on the past and try making it better to benefit our future.

Along with the rest of the backgammon world I was deeply saddened at the weekend to hear of the death of Martin Birkhan at the very young age of 47. I got to know Martin when he played in some of the London Open tournaments. He was a true gentlemen and an excellent player. We also did some commentary togther at one of the tournaments and after an interesting incident i wrote a couple of articles. In tribute to Martin the first of those articles is posted today. See if you can solve the problem - the second article with the solution will be published tomorrow.
Congratulations to Fabio Gullotta for winning the London Open Professionals Tournament for the second year in succession. He came from 2-9 down in a match to 13 to beat Raj Jansari. Raj had a great weekend because he won the London Open title and with it a superb Geoffrey Parker board. The whole tournament was a huge success and my congratulations to all involved in running it so well, especially Sean Williams, Zoe Cunningham and Mike Main.
I was commentating with Martin Birkhan of Germany on an earlier match between Julian Fetterlein (Red) and Nick Check (White) when this position arose with the score 5-3 to 11 in Nick’s favour. Julian redoubled to 4. The problem was Nick couldn’t remember doubling to 2! Neither Martin nor I could remember the initial double either. The tournament director, Mike Main, asked for the video to be replayed and we discovered that the doubling cube hadn’t be centred after the previous game.
The cube was then set to 1 in the centre, Julian doubled and Nick passed. The incident demonstrated excellent use of video technology (Sepp Blatter please note) but had it not been available it would have been interesting to see what the ruling would have been. I am still researching backgammon laws to see if there is a precedent.
Was Julian’s double to 2 correct? Should Nick have passed or taken? If the cube had been on 2 on Julian’s side of the board what would the correct cube actions have been?

There are two types of people in the world: those who can extrapolate from incomplete data sets
I am a computer Science PhD student at The University of Memphis. I am passionate about distributed computing and content centric networking. Currently, I am a member of Netlab at the university and I am involved in NDN(Name Data Networking) research project

By default, services, networks and volumes are prefixed with the project folder (the folder where the configuration file is located).
However, it is also possible to set a different prefix via the global CLI --prefix
flag (or CRANE_PREFIX
environment variable). The specified prefix is simply appended without any modification. A common use case for this feature is to launch a set of services
in parallel, e.g. for CI builds.
Another option is to set a permanent prefix in the configuration itself. This can be done via the top-level setting prefix: "foo"
. It is also possible to disable prefixing altogether with prefix: false
.
default
which has completely different semantics than user-defined networks such as foo_default
.
In order to run certain commands before or after key lifecycle events of containers, hooks can be declared in the configuration. They are run synchronously on the host where Crane is installed, outside containers, via an exec
call. They may interrupt the flow by returning a non-zero status. If shell features more advanced than basic variable expansion is required, you should explicitly spawn a shell to run the command in (sh -c 'ls *'
).
Hooks are declared at the top level of the configuration, under the hooks
key. See YAML example below:
services:
service1:
image: busybox
detach: true
command: ["sleep", "50"]
service2:
image: busybox
detach: true
command: ["sleep", "50"]
service3:
image: busybox
detach: true
command: ["sleep", "50"]
groups:
foo:
- service1
- service2
bar:
- service2
- service3
hooks:
foo:
post-start: echo container from foo started
bar:
post-stop: echo container from bar stopped
service3:
post-stop: echo container service3 stopped
Hooks can be defined on a group level (foo
, bar
) so that they apply to all services within that group, or directly on a container (service3
). At most one hook can be registered per container and per event. When more than one hook is found for a given container and a given event, the following rules apply:
service3
.foo
and bar
both contain service2
, the hooks they declare are disjoint.The following hooks are currently available:
pre-build
: Executed before building an imagepost-build
: Executed after building an imagepre-start
: Executed before starting or running a containerpost-start
: Executed after starting or running a containerpre-stop
: Executed before stopping, killing or removing a running containerpost-stop
: Executed after stopping, killing or removing a running containerEvery hook will have the name of the container for which this hook runs available as the environment variable CRANE_HOOKED_CONTAINER
.
A typical example for a hook is waiting for some service to become available:
until `docker exec postgres-build psql -c 'select now()' 1>/dev/null 2>/dev/null`
do echo Waiting for Postgres to start ...
sleep 1
done
By default, Crane executes all commands sequentially. However, you might want
to increase the level of parallelism for network-heavy operations, in order to
cut down the overall run time. The --parallel
/-l
flag allows you to
specify the level of parallelism for commands where network can be a
bottleneck (namely provision
and up
). Passing a value of 0 effectively
disable throttling, which means that all provisioning will be done in parallel.
By using a the --tag
flag, it is possible to globally overrides image tags. If
you specify --tag 2.0-rc2
, an image name repo/app:1.0
is treated as
repo/app:2.0-rc2
. The CRANE_TAG
environment variable can also be used to
set the global tag.
The generate
command can transform (part of) the configuration based on a
given template, making it easy to re-use the configuation with other tools.
--template
is a required flag, which should point to a Go template. By
default, the output is printed to STDOUT. It can also be written to a file using
the --output
flag. If the given filename contains %s
, then multiple files
are written (one per container), substituting %s
with the name of the
container. For each container, an object of type
ContainerInfo
is passed to the template. If one file is generated for all targeted containers,
a list of containers is located under the key Containers
. This feature is
experimental, which means it can be changed or even removed in every minor
version update.
 They allow you to easily avoid duplicated code in your crane.yml
file. As a example, imagine you need to define 2 different services: web
and admin
. They share almost the same configuration except the cmd
declaration. And imagine you also need 2 instances for each one for using with a node balancer. Then you can declare them as simply:
services:
web1: &web
image: my-web-app
link: ["db:db"]
...
cmd: web
web2: *web
admin1: &admin { <<: *web, command: admin }
admin2: *admin
As a summary, &anchor
declares the anchor property, *alias
is the alias indicator to simply copy the mapping it references, and <<: *merge
includes all the mapping but let you override some keys.
Basic environment variable expansion (${FOO}
, $FOO
) is supported throughout the configuration, but advanced shell features such as command substitution ($(cat foo)
, `cat foo`
) or advanced expansions (sp{el,il,al}l
, foo*
, ~/project
, $((A * B))
, ${PARAMETER#PATTERN}
) are not as the Docker CLI is called directly. Use $$
for escaping a raw $
.
A use case for this is to pass an environment variable from the CLI to the container "at runtime". If your configuration contains env: ["FOO=$FOO"]
, then FOO=hello crane run ubuntu bash
has access to $FOO
with the value of hello
.

The last post introduced the idea of using containers such as arrays and hashes to hold collections of objects. One of the goals of storing objects in a collection is so we can perform various operation on them. The Enumerable module provides methods that can be used to manipulate arrays and hashes, including transforming one to and from the other.
Suppose I have a list of books stored in an array and I would like to group them based on the length of their titles, I could call the #group_by method on the "books" array:
The #group_by method transfoms the array into a hash with titles as the value and lengths as the key:
To carry it a little further, I can also arrange a list based on the results of executing a code block:
Here, the numbers are returned as values in the hash and the keys are the outcome from evalutating the expression "i % 3".
Selecting and grouping elements in a list are commonly used data operations. Once grouped, they can be sorted, filtered, or otherwise transformed. These simple examples demonstrate one of the basic Ruby techniques for organizing data. In future posts we will see how this method can be combined with other methods to meet the needs of a variety of selection scenarios in our programs.

In order to help automate and simplify the generation of Bokeh documentation, several Sphinx extensions have been created. Most of these will not be of general interest, except for bokeh.sphinxext.bokeh_plot, which allows anyone to include and embed bokeh plots directly in their own Sphinx docs.
Integrate Bokeh extensions into Sphinx autodoc.
Ensures that autodoc directives such as autoclass automatically use Bokeh-specific directives (e.g., bokeh-prop and bokeh-model) when appropriate.
Generate a gallery of Bokeh plots from a configuration file.
Simplify linking to Bokeh Github resources.
This module proved four new roles that can be uses to easily link to various resources in the Bokeh Github repository:
:bokeh-commit: : link to a specific commit
:bokeh-issue: : link to an issue
:bokeh-milestone: : link to a milestone page
:bokeh-pull: : link to a pull request
Examples
The following code:
The repo history shows that :bokeh-commit:`bf19bcb` was made in
in :bokeh-pull:`1698`,which closed :bokeh-issue:`1694` as part of
:bokeh-milestone:`0.8`.
yields the output:
The repo history shows that commit bf19bcb was made in in pull request 1698,which closed issue 1694 as part of milestone 0.8.
Thoroughly document Bokeh model classes.
The bokeh-model directive will automatically document all the attributes (including Bokeh properties) of a Bokeh model class. A JSON prototype showing all the possible JSON fields will also be generated.
This directive takes the path to a Bokeh model class as an argument:
.. bokeh-model:: bokeh.sphinxext.sample.Foo
Examples
For the following definition of bokeh.sphinxext.sample.Foo:
class Foo(PlotObject):
''' This is a Foo model. '''
index = Either(Auto, Enum('abc', 'def', 'xzy'), help="doc for index")
value = Tuple(Float, Float, help="doc for value")
the above usage yields the output:
- class Foo(**kwargs)¶
Bases: bokeh.plot_object.PlotObject
This is a Foo model.
[ { "attributes": { "doc": null, "id": "b7b84bad-a2c9-4b46-b8b8-5aa79c0a704d", "index": "auto", "name": null, "tags": [], "value": null }, "id": "b7b84bad-a2c9-4b46-b8b8-5aa79c0a704d", "type": "Foo" } ]
Generate color representations of all known Bokeh palettes.
This directive takes no arguments.
Include Bokeh plots in Sphinx HTML documentation.
For other output types, the placeholder text [graph] will be generated.
The bokeh-plot directive can be used by either supplying:
A path to a source file as the argument to the directive:
.. bokeh-plot:: path/to/plot.py
Inline code as the content of the directive:
.. bokeh-plot::
from bokeh.plotting import figure, output_file, show
output_file("example.html")
x = [1, 2, 3, 4, 5]
y = [6, 7, 6, 4, 5]
p = figure(title="example", plot_width=300, plot_height=300)
p.line(x, y, line_width=2)
p.circle(x, y, size=10, fill_color="white")
show(p)
This directive also works in conjunction with Sphinx autodoc, when used in docstrings.
The bokeh-plot directive accepts the following options:
Examples
The inline example code above produces the following output:
from bokeh.plotting import figure, output_file, show
output_file("example.html")
x = [1, 2, 3, 4, 5]
y = [6, 7, 6, 4, 5]
p = figure(title="example", plot_width=300, plot_height=300)
p.line(x, y, line_width=2)
p.circle(x, y, size=10, fill_color="white")
show(p)
Thoroughly document Bokeh property attributes.
The bokeh-prop directive generates useful type information for the property attribute, including cross links to the relevant property types. Additionally, any per-attribute docstrings are also displayed.
This directive takes the path to an attribute on a Bokeh model class as an argument:
.. bokeh-prop:: bokeh.sphinxext.sample.Bar.thing
Examples
For the following definition of bokeh.sphinxext.sample.Bar:
class Bar(PlotObject):
''' This is a Bar model. '''
thing = List(Int, help="doc for thing")
the above usage yields the output:
Display code blocks in collapsible sections when outputting to HTML.
This directive takes a heading to use for the collapsible code block:
.. collapsible-code-block:: python
:heading: Some Code
from __future__ import print_function
print("Hello, Bokeh!")
This directive is identical to the standard code-block directive that Sphinx supplies, with the addition of one new option:
Examples
The inline example code above produces the following output:
from __future__ import print_function
print("Hello, Bokeh!")

# How to set-up HDIM Stratus from scratch
## Start AWS EC2 instance
From EC2 Management Console choose Launch Instance.
At the Choose AMI screen choose Ubuntu Server 16.04 LTS (HVM), SSD Volume Type - ami-835b4efa or similar.
Choose whatever instance type is appropriate and launch it.
You will be prompted to create a new key pair for the AWS instance – create one and copy the *.pem file to local machine. This is the key-pair that will be used to login to the default ubuntu user.
## Setup initial Admin User
Log into EC2 instance as default user ubuntu.
sudo apt-get update
sudo apt-get upgrade
sudo adduser $USERNAME Create a new user to replace default ubuntu user
Type password and credentials for new user
sudo adduser $USERNAME sudo Give new user sudo privileges
sudo su $USERNAME Login into new user so that subsequent privileges will be set correctly.
mkdir .ssh
chmod 700 ./.ssh
touch .ssh/authorized_keys
chmod 600 .ssh/authorized_keys
Copy public key for new user into .ssh/authorized_keys
The new user, $USERNAME should now be able to login using ssh. At this point it is a good idea to remove the default user ubuntu with userdel -r ubuntu.

06 May 1999
Disease Outbreak Reported
Today WHO received a report from the WHO collaborating centre at the National Institute for Virology, in South Africa that a blood sample collected from the district medical officer who became ill in Watsa zone, in the northeastern part of the Democratic Republic of Congo (DRC) and died on 23 April 1999 with symptoms of haemorrhagic fever, is positive for Marburg virus. Samples from four other suspected cases were negative. Investigations will be initiated to establish whether Marburg fever was responsible for an estimated 76 cases of hemorrhagic fever (52 deaths) that have been reported in Watsa and a nearby community of Durba. Most of the cases were gold miners working in mines near Durba. Epidemiological experts from WHO Headquarters, the WHO Regional Office for Africa and WHO country offices in Kinshasa, DRC and Kampala, Uganda are joining the Médecins sans frontières (MSF Belgium and MSF Netherlands) team already in the area. Experts from the US Centers for Disease Control and Prevention and from the Institut Pasteur are also expected to arrive in the DRC within several days to join the investigation to determine the current size of the outbreak and further investigate the aetiology of the epidemic. The team will also provide technical assistance to further implement control measures. MSF is establishing a ward to isolate patients and training local healthcare staff to use barrier nursing procedures and protective equipment.
Marburg virus infections, a lethal relative of Ebola (both viruses are in the Filovirus family), are found in sub-Saharan Africa and occur infrequently. Since the virus was first recognized in 1967 when laboratory workers in Marburg, Germany and Belgrade, Yugoslavia were infected by handling monkeys and monkey tissues from animals imported from Uganda, there have only been three reports of sporadic cases (1975 in Zimbabwe and South Africa, and in 1980 and 1987 in Kenya). The virus is transmitted to people following contact with infected animals and animal tissues, and from person-to-person by close contact with infected patients and body fluids. The natural reservoirs of Marburg virus and of Ebola virus are unknown.
Both the Marburg and Ebola viruses are often characterized by the sudden onset of fever, malaise, muscle pain, headache and conjunctivitis. This is followed by sore throat, vomiting, diarrhoea, rash, and both internal and external bleeding. Liver function may be abnormal and platelet function may be impaired. No specific treatment or vaccine exists for Marburg disease. Severe cases require intensive supportive care, as patients are frequently dehydrated and in need of intravenous fluids. Experimental studies involving the use of hyperimmune sera on animals demonstrated no long-term protection against the disease after interruption of therapy.
Suspected cases should be isolated from other patients and strict barrier nursing techniques practised. All hospital personnel should be briefed on the nature of the disease and its routes of transmission. Particular emphasis should be placed on ensuring that high-risk procedures such as the placing of intravenous lines and the handling of blood, secretions, catheters and suction devices are done under barrier nursing conditions. Hospital staff should have individual gowns, gloves and masks. Gloves and masks must not be reused unless disinfected.

24-year-old man killed during farming accident in Rock County
by Stephanie FryerEDGERTON, Wis. - A 24-year-old man from Belvidere, Illinois was killed early Tuesday morning when a tractor ran over him in Rock County.
First responders were sent to a field along the 7500 block of N. Fox Road around 1:15 a.m., where the man had been riding in a farm tractor, according to Rock County Sheriff Troy Knudson.
An initial investigation indicates an 18-year-old Illinois man was driving the tractor when the victim attempted to get out of the vehicle.
Authorities believe the victim slipped on a mud-covered ladder and fell to the ground where he was struck by the rear tire of the tractor.
Farm workers on scene called for help and performed CPR until first responders arrived, Knudson said.
The identity of the victim will be released at a later time.
