--- layout: post title: "Hystrix How to implement fallback and circuit breaker" categories: [hystrix, circuitbreaker, resilincy] tags: [netflix, hystrix, circuitbreaker, resilincy] background: hystrix.png ---
Demonstrates how to use Netflix Hystrix api’s for synchronous, asynchronous execution with fallback and circuit breaker in spring (boot) application. Hystrix-javancia annotations makes easy to use hystrix with spring framework. we need to start by creating spring boot application, use spring initializer to generate sample boot application.
For maven open pom.xml and add hystrix dependencies
{% highlight xml %}For gradle add below dependencies to build.gradle
{% highlight properties %} compile group: 'com.netflix.hystrix', name: 'hystrix-core', version: '1.5.12' compile group: 'com.netflix.hystrix', name: 'hystrix-javanica', version: '1.5.12' {% endhighlight %}To run method as synchronous hystrix command you need to annotate method with @HystrixCommand annotation and graceful degradation can be achieved by declaring name of fallback method. Below test class shows how to use hystrix commonds and intentionally throwing exception in execute method to test fallback. Fallback is enabled by default, see hystrix configuration for what properties does hystrix uses and how to configure and override.
{% highlight java %} package com.kulli.hystrix.poc; import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Service; @Service public class TestSynchronous { private Logger logger = LoggerFactory.getLogger(this.getClass()); @HystrixCommand(groupKey = "testExecute", commandKey = "cmdExecute", fallbackMethod = "fallbackTest") public void execute() throws Exception { logger.debug("hystrix poc testing"); throw new RuntimeException("Throwing exception deliberately for synchronous testing"); } @HystrixCommand(groupKey = "testExecute", commandKey = "cmdExecute") public void fallbackTest() throws Exception { logger.debug("Catching failures in fallbackTest method"); } } {% endhighlight %}To process Hystrix asynchronously you should return an instance of asynchronous result in your command method as in the example below:
{% highlight java %} package com.kulli.hystrix.poc; import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Service; import java.util.concurrent.Future; @Service public class TestAsynchronous { private Logger logger = LoggerFactory.getLogger(this.getClass()); @HystrixCommand(groupKey = "testExecuteAsync", commandKey = "cmdExecuteAsync", fallbackMethod = "fallbackAsyncTest") public FuturecircuitBreaker.errorThresholdPercentage property sets the error percentage at or above which the circuit should trip open and start short-circuiting requests to fallback logic. In below example setting circuitBreaker.forceOpen to true to force short circuit and show how circuit breaker works. This property forces the circuit breaker into an open state in which it will reject all requests and forcing them to fallback method. In real time you should use circuitBreaker.errorThresholdPercentage to handle circuit breaker depends failures percentage.
{% highlight java %} package com.kulli.hystrix.poc; import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand; import com.netflix.hystrix.contrib.javanica.annotation.HystrixProperty; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.stereotype.Service; @Service public class TestSynchronousCircuitBreaker { private Logger logger = LoggerFactory.getLogger(this.getClass()); @HystrixCommand(groupKey = "executeCircuitBreaker", commandKey = "cmdCircuitTripExecute", fallbackMethod = "fallbackCircuitOpen", commandProperties = { @HystrixProperty(name = "circuitBreaker.forceOpen", value = "true") }) public void executeCircuitBreaker() throws Exception { logger.debug("hystrix circuit breaker poc testing"); throw new RuntimeException("Throwing exception deliberately for circuit breaker testing"); } public void fallbackCircuitOpen() throws Exception { logger.debug("Catching failures in fallback circuit open method"); } } {% endhighlight %}Inject HystrixCommandAspect bean into boot application configuration to test hystrix command and run spring boot application mvn spring-boot:run or you can run a Spring Boot application from your IDE as a simple Java application.
{% highlight java %} package com.kulli.hystrix.poc; import com.netflix.hystrix.contrib.javanica.aop.aspectj.HystrixCommandAspect; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.ConfigurableApplicationContext; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; @SpringBootApplication @ComponentScan public class HystrixSamplePOCApplication { public static void main(String[] args) throws Exception { ConfigurableApplicationContext context = SpringApplication.run(HystrixSamplePOCApplication.class, args); context.getBean(TestSynchronous.class).execute(); context.getBean(TestAsynchronous.class).executeAsync(); } @Bean public HystrixCommandAspect hystrixAspect() { return new HystrixCommandAspect(); } } {% endhighlight %} {% highlight log %} 2018-08-04 17:04:01.220 DEBUG 7268 --- [x-testExecute-1] com.kulli.hystrix.poc.TestSynchronous : hystrix sync poc testing 2018-08-04 17:04:01.227 DEBUG 7268 --- [x-testExecute-2] com.kulli.hystrix.poc.TestSynchronous : Catching failures in fallbackTest method 2018-08-04 17:04:01.240 DEBUG 7268 --- [tExecuteAsync-1] com.kulli.hystrix.poc.TestAsynchronous : hystrix async poc testing 2018-08-04 17:04:01.242 DEBUG 7268 --- [tExecuteAsync-2] com.kulli.hystrix.poc.TestAsynchronous : Catching failures in fallbackAsyncTest method 2018-08-04 17:04:01.244 DEBUG 7268 --- [ main] c.k.h.poc.TestSynchronousCircuitBreaker : Catching failures in fallback circuit open method {% endhighlight %}

You awaken to find that you are on a giant floating rock.
You look around to see that there are other floating rocks ahead of you.
The rock that you are standing on has two bridges connected to other rocks.

The troll tells you that if you wish to escape it's realm you must cross three bridges.
Past each bridge you must answer a question to continue.

How to run Mail For Good in development mode
This guide was written for linux-based machines (using Debian). It will also work with OSX, but you’ll need to install things differently (e.g. with Brew). Deployment on Windows is untested, and the current suggestion is to run Ubuntu in a virtual machine using software such as VirtualBox.
In development mode, Mail 4 Good has a number of useful utilities:
- Hot reloading with webpack hot middleware
- The ability to use Redux Dev Tools (a browser extension that allows for redux time travel & viewing state)
- Additional debugging information on the server
Prerequisites
Your machine should have NPM and Node >=7.6x installed. It will also need Redis and Postgres. A full guide for installing each of these is given below. Before you install any packages, ensure your package list is up to date with:
sudo apt-get update
NPM
sudo apt-get install -y npm
Node
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
Redis
sudo apt-get install -y redis-server
Postgres
sudo apt-get install -y postgresql postgresql-contrib
Setup
*Before you start, run node -v
and ensure you are using >=7.6x. Check out node version manager for an easy way to handle this.
- Clone the repository. If you have forked the repo, make sure you clone the fork rather than the link below.
git clone https://github.com/freeCodeCamp/Mail-for-Good.git
- Change into the cloned directory. Install packages.
cd Mail-for-Good && npm install
- Set up your Google API key with this guide. There are only a few environment variables that need to be changed, these are listed below.
mv .env.example .env
# You need to edit the .env file. You can use nano, vim, atom, gedit - take your pick.
nano .env
# EXAMPLE .env FILE
GOOGLE_CONSUMER_KEY= Put your consumer key from Google here
GOOGLE_CONSUMER_SECRET= Put your consumer secret key from Google here
GOOGLE_CALLBACK= Put your Google Authorised redirect URI here (we use http://localhost:8080/auth/google/callback)
ENCRYPTION_PASSWORD= Put a long random password here, you don't need to remember it yourself
# The below lines are for configuring Postgres.
# If you know what you're doing, feel free to ignore the suggestions.
PSQL_USERNAME= Put your username here (which can be found with the command 'whoami')
PSQL_PASSWORD= Put the password you intend to use for your Postgres user here
PSQL_DATABASE= Put 'mail_for_good' here
- Start both redis-server and postgresql as background services.
sudo service redis-server start
sudo service postgresql start
# You can stop these services by replacing 'start' with 'stop', restart them with 'restart', and
# check their status with 'status'.
- We now need to configure the Postgres DB. We’ll keep this part as simple as possible, but feel free to setup your own config if you wish.
# Running the command below will let you know your username.
whoami
# When you run the command below, enter your username and password. Answer 'y' when asked to be a superuser.
# Make sure the username and password match those specified in the .env file.
sudo -u postgres createuser --interactive --pwprompt
# Next, we need to create a database.
# feel free to skip this step and customise things on your own if you wish.
# The .env.example file contains info on environment variables used with PSQL.
createdb mail_for_good
– Done! Run the command below then check out http://localhost:8080
npm run dev

There is a lot of data and information about different mental health diseases. There are many papers describing prevalence rates of mental disorders. However, based on my experience these papers use tables instead of visualizations to show the data. Moreover, if visualizations are used it is complicated and academic.
This website provides clear visualizations (Namely a bar chart, heatmap and zoomable sunburst) for the prevalence of suicide with data from the whole world. It also zooms in to the United States and visualizes suicidal thoughts and depression rates, per state. It will have interactive components which can make the data clearer, understandable and perhaps more interesting for non-academics.


Scroll Spy is a tool directive designed to help navigation elements determine the element currently in view of the user.
It takes in an array of tags to track, and when one of those tags goes over the top scroll limit, an event is fired.
fdScrollSpy
Standard Scroll Spy
This example does not modify the fireEmpty
input, so the navigation will always have an arrow.
To have the arrow not display if a user scrolls to the absolute top or bottom, set fireEmpty
to true.

With SmartConfig you can setup a strongly typed configuration within a few minutes.
Reusable
.Where
now allows you to specify an expression for the column name.LoadFailedEvent
and the TryLoad
method from the Configuration
. The new Reload
method now throws exceptions.The core package on NuGet: Install-Package SmartConfig
contains just the core functionality. You need to install a data store to be able to use it.
To create a configuration you need to define a static class and decorate it with the [SmartConfig]
attribute. It can contain any number of static properties and nested classes.
The below example show all kinds of settings that are supported by SmartConfig.
Among the simple types you can also use complex types. In order to use them you need to specify them as JSON and add the Converters
attribute to the configuration where you specify the exact converters for them.
Another possibility to specify collections, especially dynamic ones is by using the [Itemized]
attribute. This means that each item of the collection is stored in a separate row in the data store. Arrays are required to have an additional [index]
but the number actually doesn't matter. Dictionary keys can be of any type supported by the converters (int
, string
, enum
etc.).
[SmartConfig]
[Converters(
typeof(JsonToObjectConverter<int[]>),
typeof(JsonToObjectConverter<Dictionary<string, int>>)
)]
public static class FullConfig
{
public static string StringSetting { get; set; }
[Optional]
public static string OptionalStringSetting { get; set; } = "Waldo";
public static int[] ArraySetting1 { get; set; }
[Itemized]
public static int[] ArraySetting2 { get; set; }
public static Dictionary<string, int> DictionarySetting1 { get; set; }
[Itemized]
public static Dictionary<string, int> DictionarySetting2 { get; set; }
public static class NestedConfig
{
public static string StringSetting { get; set; }
}
[Ignore]
public static class IgnoredConfig
{
public static string StringSetting { get; set; } = "Grault";
}
}
You load the configuration by specifying the source with the From
method and the configuration.
Loading a configuration from an app.config
is as simple as this:
Configuration.Load
.From(new AppSettingsStore())
.Select(typeof(FullConfig));
The respecitve app.config
file:
<appSettings>
<add key="StringSetting" value="Foo"/>
<add key="ArraySetting2[0]" value="5"/>
<add key="ArraySetting2[1]" value="8"/>
<add key="DictionarySetting2[foo]" value="21"/>
<add key="DictionarySetting2[bar]" value="34"/>
<add key="NestedConfig.StringSetting" value="Bar"/>
<add key="IgnoredConfig.StringSetting" value="Qux"/>
</appSettings>
That's all.
Using a database is not that different. You just need to specify another data store:
Configuration.Load
.From(new SqlServerStore("name=SmartConfigTest"))
.Select(typeof(FullConfig));
For this example you need to have the following table:
CREATE TABLE [dbo].[Setting](
[Name] [nvarchar](50) NOT NULL,
[Value] [nvarchar](max) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
The same applies to other data sources:
SQLiteStore
Configuration.Load
.From(new SQLiteStore("name=configdb"))
.Select(typeof(FullConfig));
RegistryStore
const string TestRegistryKey = @"Software\SmartConfig\Tests";
Configuration.Load
.From(RegistryStore.CreateForCurrentUser(TestRegistryKey))
.Select(typeof(FullConfig));
With SmartConfig it is possible to use more then one identifier (Name) for a setting. The additional criteria are called attributes and allow us to further describe a setting. Not all data stores allow this. That's why we use a database in this example.
A common example is the Environment.
The config class itself does not change at all. You add the attribute when loading:
Configuration.Load
.From(new SqlServerStore("name=SmartConfigTest").Column("Environment", SqlDbType.NVarChar, 200))
.Where("Environment", "Qux")
.Select(typeof(FullConfig));
Here we've added the Where
to set the Environment and we configured the Environment column by setting its data-type and length.
The respecitve table is:
CREATE TABLE [dbo].[Setting](
[Name] [nvarchar](50) NOT NULL,
[Value] [nvarchar](max) NULL,
[Environment] [nvarchar](50) NOT NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
SmartConfig already supports a lot of data types:
sbyte
, byte
, char
, short
, ushort
, int
, uint
, long
, ulong
float
, double
decimal
, bool
, Enum
, DateTime
, string
Name
(Red), Hex
(#FF00AA), Decimal
(122, 134,90)In most cases for complex data structures we would want to use json. To be able to parse your type you first need to register a new converter. You add it with an attribute to your config class:
[SmartConfig]
[Converters(typeof(JsonToObjectConverter<List<Int32>>))]
public static class FullConfig
{
public static List<int> JsonArray { get; set; } // "[1, 2, 3]"
}
Now SmartConfig knows how to deserialize the list.

It is convenient to be able to wait for the completion of any, some, or all the operations in a list, rather than having to wait for a specific message. A call to MPI_WAITANY or MPI_TESTANY can be used to wait for the completion of one out of several operations. A call to MPI_WAITALL or MPI_TESTALL can be used to wait for all pending operations in a list. A call to MPI_WAITSOME or MPI_TESTSOME can be used to complete all enabled operations in a list.
| MPI_WAITANY (count, array_of_requests, index, status) | |
| IN count | list length (non-negative integer) |
| INOUT array_of_requests | array of requests (array of handles) |
| OUT index | index of handle for operation that completed (integer) |
| OUT status | status object (Status) |
int MPI_Waitany(int count, MPI_Request *array_of_requests, int *index, MPI_Status *status)
MPI_WAITANY(COUNT, ARRAY_OF_REQUESTS, INDEX, STATUS, IERROR)
Blocks until one of the operations associated with the active
requests in the array has completed.
If more then one operation is
enabled and can terminate, one is arbitrarily chosen.
Returns in index the index
of that request in the array and returns in status the status of the
completing communication.
(The array is indexed from zero in C, and from one in Fortran.)
If the request was allocated by a nonblocking communication operation, then it
is deallocated and the request handle is set to MPI_REQUEST_NULL.
The array_of_requests list may contain null or inactive
handles.
If the list contains no active handles (list has length zero or all
entries are null or inactive),
then the call returns immediately with index =
MPI_UNDEFINED, and a empty status.
The execution of MPI_WAITANY(count, array_of_requests, index,
status) has the same effect as the execution of
MPI_WAIT(&array_of_requests[i], status),
where i is the value
returned by index (unless the value of index
is MPI_UNDEFINED).
MPI_WAITANY with an array containing one active entry
is equivalent to MPI_WAIT.
int MPI_Testany(int count, MPI_Request *array_of_requests, int *index, int *flag, MPI_Status *status)
MPI_TESTANY(COUNT, ARRAY_OF_REQUESTS, INDEX, FLAG, STATUS, IERROR)
Tests for completion of
either one or none of the operations associated with active handles.
In the former case, it returns flag = true,
returns in index the index of this request in the array,
and returns in status the status of that operation; if the request was
allocated by a nonblocking communication call then the request is deallocated
and the handle is set to MPI_REQUEST_NULL.
(The array is indexed from zero in C, and from one in Fortran.)
In the latter case (no operation completed), it returns flag =
false, returns a value
of MPI_UNDEFINED in index and status is
undefined.
The array may contain null or inactive handles.
If the
array contains no active handles then the call returns
immediately with flag = true,
index = MPI_UNDEFINED, and an empty status.
If the array of requests contains active handles then
the execution of MPI_TESTANY(count, array_of_requests,
index, status) has the same effect as the execution of
MPI_TEST( &array_of_requests[i], flag, status),
for i=0, 1 ,..., count-1,
in some arbitrary order, until one call returns flag = true, or
all fail. In the former case, index is set to the last value of i,
and in the latter case, it is set to MPI_UNDEFINED.
MPI_TESTANY with an array containing one active entry
is equivalent to MPI_TEST.
2.2
int MPI_Waitall(int count, MPI_Request *array_of_requests, MPI_Status *array_of_statuses)
MPI_WAITALL(COUNT, ARRAY_OF_REQUESTS, ARRAY_OF_STATUSES, IERROR)
Blocks until all communication operations associated with active handles
in the list complete, and return the status of all these operations
(this includes the case where no handle in the list is active).
Both arrays have the same number of valid entries. The i-th entry in
array_of_statuses is set to the return status of the
i-th operation.
Requests that were created by nonblocking communication operations are
deallocated and the corresponding handles in the array are set to
MPI_REQUEST_NULL.
The list may contain null or inactive handles.
The call sets to empty the status of each such entry.
The error-free execution of MPI_WAITALL(count, array_of_requests,
array_of_statuses) has the same effect as the execution of
When one or more of the communications completed by a
call to MPI_WAITALL fail, it is
desireable to return specific information on each
communication. The function MPI_WAITALL will return in such
case the error code MPI_ERR_IN_STATUS and will set the
error field of each status to a specific error code. This code will be
MPI_SUCCESS, if the specific communication completed; it will
be another specific error code, if it failed;
or it can be MPI_ERR_PENDING if it has neither failed nor completed.
The function MPI_WAITALL will return MPI_SUCCESS if no request
had an error,
or will return another error code if it failed
for other reasons (such as invalid arguments). In such cases, it will
not update the error fields of the statuses.
This design streamlines error handling in the application.
The application code need only test the (single) function result to
determine if an error has occurred. It needs to check each individual
status only when an error occurred.
( End of rationale.)
int MPI_Testall(int count, MPI_Request *array_of_requests, int *flag, MPI_Status *array_of_statuses)
MPI_TESTALL(COUNT, ARRAY_OF_REQUESTS, FLAG, ARRAY_OF_STATUSES, IERROR)
Returns flag = true
if all communications associated
with active handles in the array have completed (this includes the
case where no handle in the list is active).
In this case, each status entry that corresponds to an active handle
request
is set to the status of the corresponding communication; if the request was
allocated by a nonblocking communication call then it is deallocated, and
the handle is set to MPI_REQUEST_NULL.
Each status entry that corresponds to a null or inactive
handle is set to empty.
Otherwise,
flag = false is returned, no request is modified
and the values of the status entries are undefined.
This is a local operation.
Errors that occurred during the execution of MPI_TESTALL
are handled as errors in MPI_WAITALL.
int MPI_Waitsome(int incount, MPI_Request *array_of_requests, int *outcount, int *array_of_indices, MPI_Status *array_of_statuses)
MPI_WAITSOME(INCOUNT, ARRAY_OF_REQUESTS, OUTCOUNT, ARRAY_OF_INDICES, ARRAY_OF_STATUSES, IERROR)
If the list contains no active handles, then the
call returns immediately with outcount = MPI_UNDEFINED.
When one or more of the communications completed by
MPI_WAITSOME fails, then it is desirable to return specific
information on each communication.
The arguments outcount,
array_of_indices and array_of_statuses will be
adjusted to indicate completion of all communications that have
succeeded or failed. The call will return the error code
MPI_ERR_IN_STATUS and the error field of each status
returned will be set to indicate success or to indicate the specific error
that occurred. The call will return MPI_SUCCESS if no request
resulted in an error,
and will return another error code if it failed
for other reasons (such as invalid arguments). In such cases, it will
not update the error fields of the statuses.
int MPI_Testsome(int incount, MPI_Request *array_of_requests, int *outcount, int *array_of_indices, MPI_Status *array_of_statuses)
MPI_TESTSOME(INCOUNT, ARRAY_OF_REQUESTS, OUTCOUNT, ARRAY_OF_INDICES, ARRAY_OF_STATUSES, IERROR)
MPI_TESTSOME is a local operation, which returns
immediately, whereas
MPI_WAITSOME will
block until a communication completes, if it was
passed a list that contains at least one active handle. Both calls fulfill a
fairness requirement: If a request for a receive repeatedly
appears in a list of requests passed to MPI_WAITSOME or
MPI_TESTSOME, and a matching send has been posted, then the receive
will eventually succeed, unless the send is satisfied by another receive; and
similarly for send requests.
Errors that occur during the execution of MPI_TESTSOME are
handled as for
The use of MPI_TESTSOME is likely to be more efficient than the use
of MPI_TESTANY. The former returns information on all
completed communications, with the latter, a new call is required for
each communication that completes.
A server with multiple clients can use MPI_WAITSOME so as not to
starve any client. Clients send messages to the server with service
requests. The server calls MPI_WAITSOME with one receive request
for each client, and then handles all receives that completed.
If a call to MPI_WAITANY is used instead, then one client
could starve while requests from another client always sneak in first.
( End of advice to users.)
MPI_TESTSOME should complete as many pending communications as
possible.
( End of advice to implementors.)

B.I.C. Markets Offering MT5 as Part of Southeast Asian Push
by Jeff PattersonThe financial services industry continues to see the proliferation of the MetaTrader 5 (MT5) platform in 2019. This includes a fresh push in Southeast Asia with Cambodian derivatives broker B.I.C Markets launching MT5, per a company statement.
MT5 has seen its availability rise across global markets, with many more brokers than ever before shifting to the newer variant over industry standard MT4. This stance was echoed by Bun Sovatdy, Chief Executive Officer of B.I.C. Markets.
“MetaTrader 5 is a more intuitive trading platform from both a front and back-end perspective, compared to its predecessor,” Sovatdy explained.
The move has been one of the more consistent trends in what has been a tumultuous year across the financial services industry, namely due to regulatory forces.
For its part, B.I.C. Markets operates as a leading derivatives broker in Cambodia and is the first company to launch the multi-asset trading platform domestically.
Suggested articles

In doing so, the launch of MT5 will help position the company to absorb more clients and offer a broader suite of services.
Cambodia itself has also seen a larger swath of trading activity in recent years, with renewed interest from brokers looking to shift their focus from European jurisdictions.
With a bourgeoning population, the country is an ideal destination serving as an untapped resource for clients.
It will be interesting to see if 2020 will continue this assimilation of MT5, in particular across Southeast Asia. B.I.C. Markets team is looking to MT5 to serve as a springboard for its own ambitions in the region as well.
Per the launch, B.I.C. Markets will be supporting a wide range of new features under MetaTrader 5, which includes the following:
- Full set of financial instruments
- Leverage up to 1:400
- Hedging capabilities
- Account opening functionality with integrated back office

ULEE'S GOLD A film review by Mark R. Leeper
Capsule: A Florida beekeeper foils two petty hoods while he saves his family. This same plot could have been a simple--even a bad--crime film. What makes this better than simple cable fare are the deep emotional resonance, the textured filmmaking, and the fine performances. This is a moving story of what a single man can accomplish. Rating: low +2 (-4 to +4) 7 (0 to 10) New York Critics: 18 positive, 0 negative, 4 mixed
Ulysses "Ulee" Jackson (played by Peter Fonda) is a beekeeper from a small, sweaty town in the Florida panhandle. He lives with his two granddaughters (Vanessa Zima and Jessica Biel) in what in a nicer neighborhood would be called a "dysfunctional" family. The older granddaughter is a little wild and does not have a lot of respect for her grandfather. Ulee's son-in-law Jimmy (Tom Wood) is in the penitentiary for robbing an armored car. And his daughter-in-law Helen has run off to have a good time, leaving her two daughters to Ulee. Hurt by the most of the people he loved, Ulee has withdrawn into himself emotionally. He relies on nobody and nobody can let him down. He has trained his family to never ask the help of outsiders. Above all he maintains his integrity and his dignity, even at the expense of a backache or two or not meeting his honey production goals.
Then Jimmy gets word from his two partners in the robbery, still free, that they have Helen in Orlando, high on drugs, and they want someone to take her off their hands. When Ulee comes to pick her up, they make clear how they have used her and at the same time tell Ulee that they want the $100,000 of bank money from the robbery that they just found out that Jimmy had and hid from them and the police. Ulee brings home Helen, but finds that she is too much to handle in drug withdrawal and he is forced to ask help of the nurse who rents from Ulee a house across the street from his house. Ulee wants as little help as he can manage, but it is the time of year he needs to give a lot of attention to his business of producing honey.
Peter Fonda has never been the most expressive of actors, but here it works to his advantage playing a man who has retreated into his shell and divorced himself from his emotions. This is being called the best role of Fonda's career, but it may be just a matter of calling for the type of non-emotive acting that Fonda is best at. The entire cast does well with Steven Flynn and Dewey Weber genuinely detestable as Jimmy's two slimy partners.
The film DEAD CALM would have been a standard stalker if it had not included some fascinating scenes of how Sam Neill, as a nautical man, saves a foundering yacht. Just seeing the processes used by an expert makes for some good filmmaking. Though ULEE'S GOLD does not take full advantage some of the most interesting scenes of the film show how Ulee maintains the hives and the discussions of rotating the hives and the various grades of honey. In addition these scenes characterize Ulee as a careful and contentious man who does things a step at a time. His care to repair the hives and to return the bees that have strayed makes a metaphor for Ulee's care for his home. Later his behavior around the bees is his guide for how to handle the two hoodlums who threaten his family. Unfortunately only in certain scenes is it clear what Fonda is doing with the hives. This is not a documentary on beekeeping, but it would not have taken a lot of effort to make the task a little more comprehensible. Though even as it is it does engage the viewer.
Victor Nunez tells a simple powerful story of emotional depth. I rate it a low +2 on the -4 to +4 scale.

China central bank cracks down on cryptocurrency trading in Shanghai
SHANGHAI: China's central bank launched on Friday a fresh crackdown on cryptocurrency trading in the financial hub of Shanghai, after Beijing's promotion of blockchain technology reignited interest in virtual currencies.
The move came a day after financial regulators in Shenzhen launched a similar campaign, and as the People's Bank of China (PBOC) is preparing to launch its own digital currency.
PBOC's Shanghai headquarters said in a statement it would crack down on a resurgence of illegal activities around virtual currencies, and cautioned investors not to confuse such instruments with blockchain technology.
"The issuance, financing and trading of virtual currencies involve multiple risks," PBOC said, vowing to uproot such activities.
Bitcoin's price , which had dropped roughly 20 per cent this month, extended its slide following the PBOC statement.
China launched a nationwide crackdown on cryptocurrencies in 2017, but interest in such currencies revived after Chinese President Xi Jinping said last month China should accelerate the development of blockchain technology, a digital ledger that forms the backbone of many cryptocurrencies such as bitcoin.
Xi's remarks also sparked a rush into the shares of companies engaged in, or believed to be engaged in, blockchain or digital currency-related businesses.
PBOC said last week it had not issued any digital currencies nor authorised any asset trading platforms to trade such currencies.
PBOC's Shanghai headquarters said it busted 13 platforms for initial coin offerings (ICOs) and 10 platforms for virtual currency trading during the previous crackdown in 2017.
The central bank added that it is still studying and testing its own digital currency.
PBOC is stepping up efforts to roll out its own digital currency, officially called Digital Currency Electronic Payment (DCEP), partly to fend off potential threats from Facebook's proposed digital currency Libra.


[gecode-users] changing a Space's AFC decay factor

Exactly, it is a double because of the decay factor (it used to be a double
before because of the extended range of a double compared to an integer).

I see -- I guess this is (mainly?) for setting the initial value of the
AFCs, defaulting to 1 for each propagator so that the AFC for a variable is
its degree, corresponding to the 'weighted degree' definition?
I am still a bit puzzled, I thought the AFC for a variable is an integer
-- certainly the code I use to get AFC returns an integer (using
IntVar::afc()), but the a in afc_set(a) is a double. Has the internal
representation of AFC changed from integer to double? Is this related to the
introduction of the decay factor -- without the decay factor, it seems to me
that the AFC need only be integer.

Jada Pinkett Smith Teases Fans With A Photo From The Much-Awaited Controversial Interview With Tiny Harris And T.I. Following The Deyjah Harris Drama
by Alexis StoneJada Pinkett Smith has an interview on Red Table Talk with Tiny Harris and T.I. after the controversial subject involving the rapper and his daughter, Deyjah Harris. You may recall that he found himself in hot water following some inappropriate comments about Deyjah.
He publicly stated that he regularly goes with her to the gynecologist just to make sure that she is still a virgin.
Tip received a lot of backlash after these comments and people called him controlling and sexist.
Now, Jada teased her IG followers with a photo from the upcoming interview that will air tomorrow.
‘Join me for an extremely candid conversation with T.I. and Tiny about his recent controversial comments. This Monday on @redtabletalk,’ Jada captioned the photo.
Someone commented: ‘Willow better come in the second half of this episode to give a young perspective.’
A follower said: ‘I can’t wait 😊 , My Dad is very authoritative too. I know what it’s like to have a strict Dad. I use it to hate it when I was younger but now I see it as he was only protecting me.’
One other commenter wrote: ‘Their daughter’s virginity. Wtf isn’t their daughter at the table then? This is soooo “UGH” 🙄’
A follower noticed that ‘Even in this screenshot, he looks like he still doesn’t get it lol He gone double-down defending that weird mess… I just know it.’
Will you be watching the interview tomorrow?

I heard about Sceletium Tortuosum on the internet. I first bought 1 gram. It was the traditional brown preparation. I separated the finest powder to insufflate it, and I smodked the rest. I found out that it was effective as a mood shifter by itself or smoked in a damiana cigarette, and as a Cannabis booster. So I ordered 20 more grams.
Again I separated the finest power with a towe in order to sniff it(the more pleasurable way). The effects are quicker and different this way. I smoked the rest with damiana or pot, and sometimes chewed some, most of the time with a nicotine gum. The mix with damiana, coffee or nicotine is nice and energetic. Very quickly, I used it everyday, or nearly, sometimes many times a day. The Sceletium 'high' makes me often want more. It's one of its side effects.
After some weeks of regular use (5 days/ week - several times /day), tolerance has built up. After having used 15 grams (3 months +/-), I bought another 25, which was light green and bitter. It wasnt the traditionnal fermented preparation, but the modern heaten one. Again, I separated the finest part for sniffing.
But something was wrong. I didn't have any positive effects. It wasnt the new preparation, cause it was the same with what was left of my older supply. Everyday, I felt the urge to take some. Something like the need of a cigarette for a tobacco addict. I took repeated doses with no postive effects, but with some depression and a massive instant tiredness.
4 months after my first use I realized that I was taking too much and that it had no positive effects anymore. But It was hard not to take some everyday. I left my home for 8 days, and I avoided to take some Sceletium with me. Though I had some need for it during these 8 days, it was not a problem. When I came back, I resisted 3 days more. The need was lighter at this time.
Now, I take reduced amounts with at least 48 hours between 2 hits, more often 3 or 4 days. Everything is fine. The positive mood shift and pot amplification are back. The 'take more effect' during the high is manageable and the need to take some everyday almost disappeared.
I'm a former heavy tobacco smoker, and the need for Sceletium was very similar to the need of smoking, except that it happened only once a day, and for 5 or 10 minutes, when the need for smoking was at least 30 times a day, but lasted only 2 or 3 minutes.
So, my conclusion is :
The abuse potential of Sceletium Tortuosum is real.
The 'need for more' is a part of the high.
Tolerance builds up quickly when I use it often.
Abuse leads to tiredness and depression.
Increased dosage doesn't give more positive effects, but quickens tolerance and lead to depression.
The stimulating effect is stronger with low doses.
I was really hooked, with a need which seemed hard to resist. But fighting the habit is not so hard. Certainly easier than to fight tobacco addiction.
The secret for keeping Sceletium harmless and pleasurable is to use it at low doses and occasionally. It is not because it is legal and not a strong psychoactive that it doesnt affect you.
Now I'm rather happy with it, and the 10 or 15 grams I still possess will last a long time!

http://<IP_ADDRESS>/emoncms3/user/create
But i suppose that well link is this: (picture attached: emoncms3_image03.jpg)
http://<IP_ADDRESS>/emoncms3/index.php?q=user/create
I check that 'mod_rewrite', 'mod_deflate' and 'mod_headers' are loaded and seems active
NAS> cat /etc/httpd/conf/httpd.conf-user
..
..
LoadModule rewrite_module modules/mod_rewrite.so
LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so
..
..
Restarting apache services:
NAS> /usr/syno/etc/rc.d/S97apache-sys.sh restart
Query loaded modules:
NAS> httpd -t -D DUMP_MODULES

Syntax OK
In anoter link, says that 'libphp5.so' module must be loaded into httpd.conf-sys, but i cant find mentioned library on my system.
http://www.vanderzee.org/synology
AddType application/x-httpd-php .php
LoadModule php5_module /lib/libphp5.so
I have spent a lot of hours looking for someone whith the same problem without success. Any suggestion, please!! :-)
Re: Broken links into emonCMS on a Synology NAS
Im not familiar with SynologyNAS, but I wonder if this thread might help: http://openenergymonitor.org/emon/node/2167
Sounds like its still a mod_rewrite issue. But I would also ask why are you using emoncms v3 when there is version 8 available? Its up here: http://github.com/emoncms/emoncms
Re: Broken links into emonCMS on a Synology NAS
Hi Tristian, thanks for your quick answer,
You are in right, better install last version available (v8.2.4), but now i have a diferent error :-|
I have the same problem of 'robw':
http://openenergymonitor.org/emon/node/2167
"I get a red box under the confirm password box but it has no text or error message not even in the source html." (Attach: login failed.jpg)
I set permission folder of web app to user 'emoncms3user' and group 'http'. This group give access over web services. Also i set permision over folder /volume1/web/emoncms (Attach: login failed.jpg) This is the folder were webs apps are located.
The behaviour are the same, picture in red over user credentials after push over Login. Without response...
Users rights? No error message? some test to apply? :-(

I was told that taking 8 Unisom caps would cause a real wicked trip. I had been getting into various OTC drugs (mostly DXM), and I thought it was worth a shot. The person who told me about it weighed significantly less than I, so I figured it was 'safe' (as safe as something like sleeping pills can be...).
One night, I tried taking all 8. Sat around for awhile, with no reaction for about an hour to an hour and a half. Finally, I began feeling very strange, like my head was leaving my body... much like a bad case of medicine-head... but not unpleasant. This feeling became stronger as time passed. Finally, I hit the peak (which lasts quite long, it seems). It's hard to describe. Everything is very surreal and clouded. I was able to act completely normal, however. I asked a few of my friends (who I met with after taking the pills) if I seemed odd. They of course said 'yes', but no more so than usual ;)
Now, while the trip itself is rather fun, there was one downside to it. This is a very strange side effect, but here goes.....   I know this is odd, but it is true. I thought that it was a fluke, but the second (and last) time I took 8 caps, the same thing happened. I have no idea what could cause this, but it was quite annoying. I suppose if I were out doing stuff that did not require sitting, it would be okay.
Overall, a very interesting experience.

The ⊥IW.nano round had a peculiar unlocking structure. When solvers first opened the round, it was entitled ⊥IW.giga and the metapuzzle for that round—Rule of Three—was already solved. Solvers needed to determine that one of the puzzles in the round—Twins—was impossible to solve normally and must be backsolved from the meta. When this puzzle was backsolved, the website allowed solvers to “zoom in” to ⊥IW.kilo, a whole new round with Twins as the metapuzzle. Solvers then needed to repeat this process and backsolve a particular puzzle in ⊥IW.kilo to enter ⊥IW.milli. Finally, in ⊥IW.milli, solvers found that one of the individual puzzles was titled ⊥IW.nano. Backsolving ⊥IW.nano completed the entire round and fixed the ⊥IW.nano building.
The answer to this puzzle is a feeder to Level One—the metapuzzle of ⊥IW.milli. We know Level One has the answer LEGACY. As stated above, we must reverse-engineer how Level One worked and use that information to backsolve this puzzle.
The other answers in this round are:
CLOVER FOOD LAB INTERSTELLAR TRADE BUZZFEED THE SPICIEST MEMELORD SOUNDLINK
Indexing by the numbers listed on the meta page into the corresponding answers yields ONE.MI?—this can be completed to ONE.MIT, which clues the artwork associated with MIT.nano that contains the names of every known MIT affiliate from 1861 to 2020. This is confirmed by noting that the outer ring of the circle is the same color as the outer ring of the seal on One.MIT 2020.
| World Search | (3) | CLOVER FOOD LAB | O |
| Nutraumatic | (2) | INTERSTELLAR TRADE | N |
| Super Mystery World | (6) | BUZZFEED | E |
| . | . | ||
| Questionable Answers | (12) | THE SPICIEST MEMELORD | M |
| Telephone | (7) | SOUNDLINK | I |
| ⊥IW.nano | (1) | ? |
At this point, we might realize that each of the answers corresponds to a well-known MIT alum (though the degree of well-known-ness varies greatly).
| Answer | Alum | Letter | Notes |
|---|---|---|---|
| CLOVER FOOD LAB | Ayr Muir | L | Muir founded Clover Food Lab. |
| INTERSTELLAR TRADE | Paul Krugman | E | Krugman wrote a famous paper about interstellar trade. |
| BUZZFEED | Jonah Peretti | G | Peretti co-founded Buzzfeed. |
| THE SPICIEST MEMELORD | Lillian Chin | A | Chin wrote down “Who is the spiciest memelord?” as her final response in the 2017 Jeopardy! College Championship. |
| SOUNDLINK | Amar Bose | C | SoundLink is a brand of portable speakers manufactured by the Bose corporation, which was founded by and named after Amar Bose. |
| T????? | ????? | Y |
The One.MIT project built a website where you can look up the position of MIT affiliates’ names on the seal. Entering the above alumni on the website, we can confirm that they’re all present on One.MIT 2020.
Now we must determine how to extract the meta answer LEGACY. The seal includes the text MASSACHUSETTS INSTITUTE OF TECHNOLOGY and MENS ET MANUS in big letters, and the letters of LEGACY can be found in those phrases. A reasonable assumption is that we should use the arrows on the diagram on the meta page to point to the letters of LEGACY somehow.
All the arrows emanate from the center of the seal, but if we reposition each arrow so that its end starts at the position of a particular alum, it will point to the corresponding letter. For example, the arrow pointing towards the top left can be repositioned to point from Amar Bose’s position on the seal to the letter C.
All arrows except one are used to get from the five solvable puzzles’ answers to the letters L through C, leaving the shortest arrow pointing down and to the right.
Since there is only one remaining arrow and one unique letter Y on the seal, we can determine the position of the missing MIT alum, but we still need to find the name there. The website allows you to zoom in on an arbitrary position and view the names at that location.
If we do so precisely, we’ll find that the name at the desired position is none other than RICHARD P FEYNMAN. This, however, is not the answer to the puzzle.
We’re looking for a word or phrase that is associated with Feynman that begins with the letter T and provides a satisfying response to the grad students who “don’t have enough space for their stuff.”
Scanning through Feynman’s Wikipedia page, we might notice the name of a famous talk he gave in 1959 that is associated with the conceptual beginnings of the field of nanotechnology, which should allay the grad students’ worries: THERE'S PLENTY OF ROOM AT THE BOTTOM.
