 It was a rare moment of humour at the stuffy, elitist festival, and his reaction instantly disarmed a deadly serious audience. In short, for a few brief moments he turned Cannes into something it arguably had never been before: funny and sweet.
Benigni stars as Guido, a clever and warm Jewish-Italian waiter who relentlessly pursues "princess" Dora (Braschi) until she can no longer resist him; within a few years, they are married and with child, the inquisitive Giosué (Cantarini). But not long after Guido also realizes his dream of opening a bookstore is he herded, along with his son and uncle (Durano), to the camps. (Loving Dora, whose heritage allows her to stay behind, joins them anyway.)
Guido wants to protect Giosué from the horrible truth, so he tells his son that they are players of a complex game: the winner gets to ride in a tank! (I loved the moment when Guido voluntarily mistranslates a barking soldier's orders just so he can establish a set of "rules": no talking, hide from the mean-looking men in uniforms, and don't ask for sandwiches.) The boy's eventual suspicions force Guido to cover up his lies with more lies: one brilliant sequence has Giosué disguised as a German boy so he can enjoy a big fancy dinner at which Guido has been asked to wait tables-Giosué has no idea how close he comes to being killed after accidentally applauding his meal in Italian.
The first third of LIFE IS BEAUTIFUL is very whimsical; nothing prepares us for its narrative's left turn. Benigni moves with the grace of Fred Astaire, can take a pratfall like Buster Keaton, and at times his verbal pitter-patter is a one-man Abbott and Costello routine; Benigni is the current clown prince of cinema. (Is it any wonder Blake Edwards tried to revive the Pink Pather series with Benigni as the son of Inspector Clouseau?) It is thanks to Benigni's benign performance (his eyes project nothing but sincerity) that not one second of LIFE IS BEAUTIFUL is maudlin or cloying; that said, I can't imagine a person unmoved by the film's ending. Guido is a completely unselfish man who simply utilizes his gifts to make the best of the worst situation. He does what many a father would do, and the climax drives that point home.
Before the haunting LIFE IS BEAUTIFUL took home its Cannes award (it also recently won the Toronto International Film Festival's Audience Award), there was speculation that its subject matter might stir up controversy. By now, I'm sure the unanimously positive reaction to the film has quelled the Jewish community's (among others) fears; LIFE IS BEAUTIFUL does not make light of the holocaust whatsoever. Instead, it embraces the bravery of its victims, and educates its audience through truly accessible characters.

Don't worry - creating an account is completely free and you can use your Microsoft or Google account to register.
Flex uses OAuth2 to authenticate users to the Flex service. This makes it very simple to register and sign in, and enables features such as Single Sign On and Federated Authentication against your existing login services. So this part can be seamless if you're integrating with an existing app...
{{env.appName}} is already configured for OAuth2 'code flow'
with a 'client' previously registered with the Flex Identity
service. You can find the settings in src/environments/base

Welcome to documentation of Discord Rich Presence Client!¶
Discord is one of the most popular communicator all over the world. Discord ensures text and voice communiacton protocol for many communities. Developers of this amazing communicator gives opportunity for other independent developers to integrate thier products with Discord. One of the most interesting option is to share your’s activty with rest of the community. This can be reached with Discord Rich Presecne.
What is Discord Rich Presence?¶
Discord Rich Presence allows you to show other users in the community what are you doing right now in really elegant and efficient way. You can display status message, activity description, timestamp when you started and give opportunity to specte or join the game that you are actually playing.
About this project¶
There is official Discord Rich Presence API (discord-rpc) but officially it supports only C, C++, Unity and Unreal Engine. There are also featured some unofficial wrappers in other languages but not in Python. This project contains the simple wrapper written in Python to communicate with Discord app via inter-process communication techniques.
In the package you can find:
- The most important tools that provides methods to connect to Discord and communicate with it via Discord IPC socket.
- Simple example how to use Discord Rich Presence.
Wrapper is easily extendable, just read the code/documentation and write your own payload that covers your point of interests. It should be easy because you are developer, am I right?
Getting started¶
There is no package avaible in Python PyPi because there are only four short files that you should be interseted in:
- discord_ipc.py - Discord Rich Presence API wrapper
- os_dependencies.py - expected localizations to Discord IPC socket on specific platforms
- payloads.py - templates and descriptions of payloads that can be send to Discord
- discord_rpc_client.py - main entry point, example usage of wrapper
You can find all necessary files in folder named src, just download it.
There is no need to install requirements.txt because it contains packages needed to use Sphinx documentation tool only.
Firstly you should visit Discord developers site and register your application. After that your unique Client ID should be generated. Nextly download src folder from the repository and open file named discord_rpc_client.py.
In line 22 you should replace ClientID parameter with ID generated in last step.
ipc = discord_ipc.DiscordIPC("ClientID")
You are ready to go just save the file, open Discord app and run program with command in terminal:
python discrod_rpc_client.py
Community should see that your status changed!
Supported platforms¶
| OS | status |
|---|---|
| Windows | tested |
| Linux | tested |
| MacOS | tested |
Bugs and issues¶
If any error occured, I will be really happy to help you with the problem but it will be nice to see the error message. You can change logger mode and paste log contnet into GitHub issue page.
Replace line 23 in discord_ipc.py with:
logger_level = "DEBUG"
Ensure that file discord_ipc.log does not exist in folder where discord_ipc.py is. If file exists, delete it.
After that run program:
python discrod_rpc_client.py
Open discord_ipc.log file and copy the content.

SPEAKER-TEST(1) SPEAKER-TEST(1) NAME speaker-test - command-line speaker test tone generator for ALSA SYNOPSIS speaker-test [-options] DESCRIPTION speaker-test generates a tone that can be used to test the speakers of a computer. speaker-test by default will test the default device. If you want to test another sound device you will have first to get a list of all of the sound cards in your system and the devices associated with those cards. Notice that there might be for example, one device for analog sound, one for digital sound and one for HDMI sound. To get the list of available cards and devices you can run aplay -L. $ aplay -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=ICH5 Intel ICH5, Intel ICH5 Default Audio Device front:CARD=ICH5,DEV=0 Intel ICH5, Intel ICH5 Front speakers surround40:CARD=ICH5,DEV=0 Intel ICH5, Intel ICH5 4.0 Surround output to Front and Rear speakers (...) in the above example, there are four devices listed: null, default, front and surround40. So, if you want to test the last device you can run speaker-test -Dsurround40:ICH5 -c 6. The -c option will indicate that the six audio channels in the device have to be tested. OPTIONS -c | --channels NUM NUM channels in stream -D | --device NAME PCM device name NAME -f | --frequency FREQ sine wave of FREQ Hz --help Print usage help -b | --buffer TIME Use buffer size of TIME microseconds. When 0 is given, use the maximal buffer size. The default value is 0. -p | --period TIME Use period size of TIME microseconds. When 0 is given, the peri‐ ods given by -P option is used. The default value is 0. -P | --nperiods PERIODS Use number of periods. The default value is 4. -r | --rate RATE stream of RATE Hz -t | --test pink|sine|wav -t pink means use pink noise (default). Pink noise is perceptually uniform noise -- that is, it sounds like every frequency at once. If you can hear any tone it may indicate resonances in your speaker system or room. -t sine means to use sine wave. -t wav means to play WAV files, either pre-defined files or given via -w option. You can pass the number from 1 to 3 as a backward compatibility. -l | --nloops COUNT Specifies the number of loops. Zero means to run infinitely. When -s option below with a valid channel is given, speaker-test will perform always a single-shot without looping. -s | --speaker CHANNEL Do a single-shot speaker test for the given channel. The channel number starts from 1. The channel number corresponds to left, right, rear-left, rear-right, center, LFE, side-left, side-right, and so on. For example, when 1 is passed, it tests the left channel only once rather than both channels with looping. -w | --wavfile Use the given WAV file for the playback instead of pre-defined WAV files. -W | --wavdir Specify the directory containing WAV files for playback. The default path is /usr/share/sounds/alsa. USAGE EXAMPLES Produce stereo sound from one stereo jack: speaker-test -Dplug:front -c2 Produce 4 speaker sound from two stereo jacks: speaker-test -Dplug:surround40 -c4 Produce 5.1 speaker sound from three stereo jacks: speaker-test -Dplug:surround51 -c6 To send a nice low 75Hz tone to the Woofer and then exit without touching any other speakers: speaker-test -Dplug:surround51 -c6 -s1 -f75 To do a 2-speaker test using the spdif (coax or optical) output: speaker-test -Dplug:spdif -c2 SEE ALSO aplay(1) AUTHOR The speaker-test program was written by James Courtier-Dutton. Pink noise support was added by Nathan Hurst. Further extensions by Takashi Iwai. speaker-test April 2nd, 2011 SPEAKER-TEST(1)

Regression MovieLens Ratting¶
Here we demonstrate a Cosine Similarity Regression job in movie lens dataset. This demo will show how paddle does (word) embedding job, handles the similarity regression, the character-level convolutional networks for text, and how does paddle handle multiple types of inputs. Note that the model structure is not fine-tuned and just a demo to show how paddle works.
YOU ARE WELCOME TO BUILD A BETTER DEMO BY USING PADDLEPADDLE, AND LET US KNOW TO MAKE THIS DEMO BETTER.
Data Preparation¶
Download and extract dataset¶
We use movielens 1m dataset here. To download and unzip the dataset, simply run the following commands.
cd demo/recommendation/data
./ml_data.sh
And the directory structure of demo/recommendation/data/ml-1m
is:
+--ml-1m
+--- movies.dat # movie features
+--- ratings.dat # ratings
+--- users.dat # user features
+--- README # dataset description
Field config file¶
Field config file is used to specific the fields dataset and file format, i.e, specific WHAT type it is in each feature file.
The field config file of ml-1m shows in demo/recommendation/data/config.json
.
It specifics the field types and file names: 1) there are four types of field for user file: id, gender, age and occupation;
2) the filename is “users.dat”, and the delimiter of file is ”::”.
{
"user": {
"file": {
"name": "users.dat",
"delimiter": "::"
},
"fields": ["id", "gender", "age", "occupation"]
},
"movie": {
"file": {
"name": "movies.dat",
"delimiter": "::"
},
"fields": ["id", "title", "genres"]
}
}
Preprocess Data¶
You need to install python 3rd party libraries. IT IS HIGHLY RECOMMEND TO USE VIRTUALENV MAKE A CLEAN PYTHON ENVIRONMENT.
pip install -r requirements.txt
The general command for preprocessing the dataset is:
cd demo/recommendation
./preprocess.sh
And the detail steps are introduced as follows.
Extract Movie/User features to python object¶
There are many features in movie or user in movielens 1m dataset. Each line of rating file just provides a Movie/User id to refer each movie or user. We process the movie/user feature file first, and pickle the feature (Meta) object as a file.
Meta config file¶
Meta config file is used to specific HOW to parse each field in dataset. It could be translated from field config file, or written by hand. Its file format could be either json or yaml syntax file. Parser will automatically choose the file format by extension name.
To convert Field config file to meta config file, just run:
cd demo/recommendation/data
python config_generator.py config.json > meta_config.json
The meta config file shows below:
{
"meta": {
"movie": {
"fields": [
{
"type": "id",
"pos": 0
},
{
"regex": {
"pattern": "^(.*)\\((\\d+)\\)$",
"group_id": 1,
"strip": true
},
"type": {
"seq_type": "sequence",
"name": "embedding"
},
"dict": {
"type": "char_based"
},
"name": "title",
"pos": 1
},
{
"type": "one_hot_dense",
"dict": {
"delimiter": "|",
"type": "split"
},
"name": "genres",
"pos": 2
}
],
"file": {
"delimiter": "::",
"type": "split",
"name": "movies.dat"
}
},
"user": {
"fields": [
{
"type": "id",
"pos": 0
},
{
"type": "embedding",
"dict": {
"type": "char_based"
},
"name": "gender",
"pos": 1
},
{
"type": "embedding",
"dict": {
"sort": true,
"type": "whole_content"
},
"name": "age",
"pos": 2
},
{
"type": "embedding",
"dict": {
"sort": "true",
"type": "whole_content"
},
"name": "occupation",
"pos": 3
}
],
"file": {
"delimiter": "::",
"type": "split",
"name": "users.dat"
}
}
}
}
There are two kinds of features in meta: movie and user.
- in movie file, whose name is movies.dat
we just split each line by ”::”
pos 0 is id.
- pos 1 feature:
- name is title.
- it uses regex to parse this feature.
- it is a char based word embedding feature.
- it is a sequence.
- pos 2 feature:
- name is genres.
- type is one hot dense vector.
- dictionary is auto generated by parsing, each key is split by ‘|’
- in user file, whose name is users.dat
we just split each line by ”::”
pos 0 is id.
- pos 1 feature:
- name is gender
- just simple char based embedding.
- pos 2 feature:
- name is age
- just whole word embedding.
- embedding id will be sort by word.
- pos 3 feature:
- name is occupation.
- just simple whole word embedding.
Meta file¶
After having meta config file, we can generate Meta file, a python pickle object which stores movie/user information. The following commands could be run to generate it.
python meta_generator.py ml-1m meta.bin --config=meta_config.json
And the structure of the meta file meta.bin
is:
+--+ movie
| +--+ __meta__
| | +--+ raw_meta # each feature meta config. list
| | | +
| | | | # ID Field, we use id as key
| | | +--+ {'count': 3883, 'max': 3952, 'is_key': True, 'type': 'id', 'min': 1}
| | | |
| | | | # Titile field, the dictionary list of embedding.
| | | +--+ {'dict': [ ... ], 'type': 'embedding', 'name': 'title', 'seq': 'sequence'}
| | | |
| | | | # Genres field, the genres dictionary
| | | +--+ {'dict': [ ... ], 'type': 'one_hot_dense', 'name': 'genres'}
| | |
| | +--+ feature_map [1, 2] # a list for raw_meta index for feature field.
| | # it means there are 2 features for each key.
| | # * 0 offset of feature is raw_meta[1], Title.
| | # * 1 offset of feature is raw_meta[2], Genres.
| |
| +--+ 1 # movie 1 features
| | +
| | +---+ [[...], [...]] # title ids, genres dense vector
| |
| +--+ 2
| |
| +--+ ...
|
+--- user
+--+ __meta__
| +
| +--+ raw_meta
| | +
| | +--+ id field as user
| | |
| | +--+ {'dict': ['F', 'M'], 'type': 'embedding', 'name': 'gender', 'seq': 'no_sequence'}
| | |

Split Training/Testing files¶
We split ml-1m/ratings.dat
into a training and testing file. The way to split file is for each user, we split the
rating by two parts. So each user in testing file will have some rating information in training file.
Use separate.py to separate the training and testing file.
python split.py ml-1m/ratings.dat --delimiter="::" --test_ratio=0.1
Then two files will be generated: ml-1m/ratings.dat.train
and ml-1m/rating.data.test
.
Move them to workspace data
, shuffle the train file, and prepare the file list for paddle train.
shuf ml-1m/ratings.dat.train > ratings.dat.train
cp ml-1m/ratings.dat.test .
echo "./data/ratings.dat.train" > train.list
echo "./data/ratings.dat.test" > test.list
Neural Network Configuration¶
Trainer Config File¶
The network structure shows below.
The demo’s neural network config file “trainer_config.py” show as below.
from paddle.trainer_config_helpers import *
try:
import cPickle as pickle

def construct_feature(name):
"""

This method read from meta data. Then convert feature to neural network due
to feature type. The map relation as follow.
* id: embedding => fc

__meta__ = meta[name]['__meta__']['raw_meta']
fusion = []
for each_meta in __meta__:

slot_name = each_meta.get('name', '%s_id' % name)
if type_name == 'id':
slot_dim = each_meta['max']
embedding = embedding_layer(
input=data_layer(
slot_name, size=slot_dim), size=256)

'data/train.list',
'data/test.list',
module='dataprovider',
obj='process',
args={'meta': meta})
else:
outputs(similarity)
In this trainer_config.py
, we just map each feature type to
a feature vector, following shows how to map each feature to a vector shows below.
id
: Just simple embedding, and then add to fully connected layer.embedding
:- if is_sequence, get the embedding and do a text convolutional operation, get the average pooling result.
- if not sequence, get the embedding and add to fully connected layer.
one_host_dense
:- just two fully connected layer.
Then we combine each features of movie into one movie feature by a
fc_layer
with multiple inputs, and do the same thing to user features,
get one user feature. Then we calculate the cosine similarity of these two
features.
In these network, we use several api in trainer_config_helpers. There are
- Data Layer, data_layer
- Fully Connected Layer, fc_layer
- Embedding Layer, embedding_layer
- Context Projection Layer, context_projection
- Pooling Layer, pooling_layer
- Cosine Similarity Layer, cos_sim
- Text Convolution Pooling Layer, text_conv_pool
- Declare Python Data Sources, define_py_data_sources2
Data Provider¶
from paddle.trainer.PyDataProvider2 import *
import common_utils # parse
def hook(settings, meta, **kwargs):
"""
Init hook is invoked before process data. It will set obj.slots and store
data meta.
:param obj: global object. It will passed to process routine.

file record movie/user features.
:param kwargs: unused other arguments.
"""
del kwargs # unused kwargs

# slot types.
settings.input_types = headers
settings.meta = meta
@provider(init_hook=hook, cache=CacheType.CACHE_PASS_IN_MEM)
def process(settings, filename):
with open(filename, 'r') as f:
for line in f:
# Get a rating from file.
user_id, movie_id, score = map(int, line.split('::')[:-1])
# Scale score to [-5, +5]
score = float(score) * 2 - 5.0
# Get movie/user features by movie_id, user_id
movie_meta = settings.meta['movie'][movie_id]
user_meta = settings.meta['user'][user_id]
outputs = [movie_id - 1]
# Then add movie features
for each_meta in movie_meta:
outputs.append(each_meta)
# Then add user id.
outputs.append(user_id - 1)
# Then add user features.
for each_meta in user_meta:
outputs.append(each_meta)
# Finally, add score
outputs.append([score])
# Return data to paddle
yield outputs
The data provider just read the meta.bin and rating file, yield each sample for training.
In this dataprovider.py
, we should set:
- obj.slots: The feature types and dimension.
- use_seq: Whether this
dataprovider.py
in sequence mode or not. - process: Return each sample of data to
paddle
.
The data provider details document see there.
Train¶
After prepare data, config network, writting data provider, now we can run paddle training.
The run.sh is shown as follow:
paddle train \
--config=trainer_config.py \
--save_dir=./output \
--use_gpu=false \
--trainer_count=4\
--test_all_data_in_one_period=true \
--log_period=100 \
--dot_period=1 \
--num_passes=50 2>&1 | tee 'log.txt'
It just start a paddle training process, write the log to log.txt, then print it on screen.
Each command line argument in run.sh
, please refer to the command line
arguments page. The short description of these arguments is shown as follow.
- config: Tell paddle which file is neural network configuration.
- save_dir: Tell paddle save model into ‘./output’
- use_gpu: Use gpu or not. Default is false.
- trainer_count: The compute thread in one machine.
- test_all_data_in_one_period: Test All Data during one test period. Otherwise,
will test a
batch_size
data in one test period. - log_period: Print log after train
log_period
batches. - dot_period: Print a
.
after traindot_period
batches. - num_passes: Train at most
num_passes
.
If training process starts successfully, the output likes follow:

to stop training whenever you want.
Evaluate and Predict¶
After training several passes, you can evaluate them and get the best pass. Just run
./evaluate.sh
You will see messages like this:
Best pass is 00009, error is 3.06949, which means predict get error as 0.875998002281
evaluating from pass output/pass-00009
Then, you can predict what any user will rate a movie. Just run
python prediction.py 'output/pass-00009/'
Predictor will read user input, and predict scores. It has a command-line user interface as follows:
Input movie_id: 9
Input user_id: 4
Prediction Score is 2.56
Input movie_id: 8
Input user_id: 2
Prediction Score is 3.13

Ben Hammersley was debating with himself in public whether to dive into Ruby on Rails or stay with his trusty Perls and pick up on Maypole:
Should I learn Perl with Maypole, or Ruby on Rails? Perl I know, Ruby I don’t; Maypole seems a bit under the radar, Rails is hot hot hot; Perl has shedloads of modules to give other really useful features, Ruby has less.
I offered my always impartial and objective advice that perhaps Ruby on Rails would open his mind more. Learning a new language and all. Hammersley responded:
I’m inclined to go with his sage advice and learn a new language as well. And a new version came out this morning, too. That’s it. I’m sold.
Welcome on board, Ben!

Review: MY FAVORITE MARTIAN
Starring: Jeff Daniels, Christopher Lloyd, Daryl Hannah, Elizabeth Hurley, Ray Walston
Directed by: Donald Petrie
Review by: Joy Wyse, the SILVER Screen Critic
Anyone over the age of thirty remembers the television show, My Favorite Martian which starred Bill Bixby and Ray Walston. This movie is NOT a remake of that series. It takes place today and several changes have been made to our Martian friends. The biggest difference is that our new Martian is not alone. A silvery suit that walks and talks on its own accompanies him. It also has amazing powers.
A television producer/reporter named Tim O'Hara [Jeff Daniels] works with an on-air reporter, Brace Channing [Elizabeth Hurley] whose father is O'Hara's boss. Another co-worker is Lizzie [Daryl Hannah]. One night, while driving back from an assignment O'Hara sees a mysterious object descend from the sky and come to a stop on the beach alongside him. The alien, who later becomes known as Uncle Martin [Christopher Lloyd], has the ability to shrink the spaceship to the size of a toy.
Most of the film is comprised of the ridiculous situations that an alien encounters on earth. The buckle on Suit's belt contains chewing gum balls that allow the chewer to take on the characteristics of a specific planet.
Uncle Martin, who has three eyes, four arms, and such, upon landing, chews the Earth gum. The plot is filled with ‘dirty' kid-type humor, such as the ‘suit' mooning people, talk of US astronauts ‘wetting' in their suits, the purchase of a ‘pooper scooper', etc. There are some attempts at clever writing, but it falls short. For example, the scientist's name is Dr. E. Coli. The Hawaiian Tropics ‘Senior' competition offered humor that never materialized. It is nice to see Ray Walston in ‘familiar' surroundings.
The movie is totally ridiculous, but it's harmless. We took our 9-year-old grandson with us. He loved it, and we enjoyed it. It will never make screen history, but it's worth seeing. I give it a C+.

Hi
There seems to be a lot of interest in the ESP8266 and emoncms.
I have started this thread as a resource for any one interested.
Esp8266 forum http://www.esp8266.com/
Very useful blog http://tech.scargill.net/
I have emoncms monitoring my central heating, rain fall and a garden shed mounted DC solar system. (We live in a listed cottage and have a very small roof so grid connected PV is tricky) I use the rain fall to control a solar powered remote irrigation system locally controlled by an Arduino. I use SMS messages to monitor and control the water. The whole system is tied together using mqtt (my own broker - mosquitto) and node red running on a Pi. My emoncms is locally hosted also on a PI. (At the moment 2 Pi are used mainly for historical reasons, now I have everything pretty well debugged I think it could all run happily on a Pi2) I can control most things over the internet using thing studio:- http://www.thingstud.io/
I am working on using an ESP8266 as the local control for the irrigation and controlling via the Internet as there is now a public wifi connection I can pick up.
Regards
Ian
Re: ESP8266 and Emoncms
Ian,
there seem to be at least four different ways to use the ESP8266:
- use as a slave controller with the AT command set
- use NodeMCU firmware and LUA script programming
- write native code with the ARDUINO IDE and environment
- write native code with the Espressif SDK
Which way will you be going?
Re: ESP8266 and Emoncms
I just tested first scenario mentioned by Jorg - ESP8266 as a AT command slave for Arduino Due and it is really impressive powerfull and flexible set.
Radek
Re: ESP8266 and Emoncms
Hi Jorg
I ended up using this :- http://www.esp8266.com/viewtopic.php?f=9&t=820
It meant learning how to use basic eclipse functions but I did not find it too difficult (after a lot of google searching). The main reason was because it had the best mqtt support I could find when I first started. It uses this library:- http://www.esp8266.com/viewtopic.php?f=6&t=1031&start=40
I must admit it was mainly because that is what Peter Scargill is using and he seems to know what he is doing and he is also using the ESP8266 for a very similar application to mine.
Regards
Ian
Re: ESP8266 and Emoncms
If on your travels you should find any info on how to make a serially connected esp8266 replicate a "normal usb wifi dongle" for normal internet usage, I would be very pleased to hear about it, I did search extensively but the general consensus seems to be "yes it's capable but why bother when a usb dongle costs the same".
What the esp8266 method can do that the standard dongle cannot is power down AND power up the Pi (or reboot) and put itself to sleep, and it has a single adc that could monitor it's own battery voltage and (something you may be interested in Ian) when operating from battery it can shut down the Pi when battery voltage is low and start it again when battery voltage comes back up, whilst providing a manual override and notifications/updates in it;'s "sleep" state (ie Pi off & esp sleep 90% of the time)
Plus the esp8266 is capable of starting in AP mode and switching function, which could make a very easy WiFi configuration method, plug it on => connect to network "esp" using a smartphone => enter ssid and password => exit ap-mode so the pi can connect to your lan, job done.

Re: ESP8266 and Emoncms
I have so far done a quick test with a USB adapter and ESP8266 using the AT command set. Very impressive! Two simple commands and I had the chip connected to my WLAN, wow. But in the end I do not want to use a second microcontroller.
I have also set everything up for the Arduino environment. Sample programs compile, so there is a good chance it works if I get my final hardware (today?).
Not so much success with the setup Ian uses (http://www.esp8266.com/viewtopic.php?f=9&t=820). Everything is set up successfully, but I am not able to compile sample projects from others. Not sure about the reason, but has something to do with the makefile and location of files.

Re: ESP8266 and Emoncms
I am looking at using the ESP8266 to operate as temperature and humidity sensor plus IR remote control for an air conditioner. However it is looking more complicated than I thought it would be, mainly because of the way in which the IR commands work for the air conditioner. I really wish I had bought an air conditioner with wifi remote control. That however wouldn't have solved the problem with the older air conditioner unit.
Re: ESP8266 and Emoncms
For anyone interested in using Arduino environment for programming of ESP8266:
I tried to program the NodeMCU hardware using the setup described here:
https://github.com/esp8266/Arduino
It has cost me some hours now to find out that the 'stable' version to use the boardmanager:
http://arduino.esp8266.com/stable/package_esp8266com_index.json
does not work. The NodeMCU hardware uses a different layout/addressing of the flash and some variants of the ESPxx chips might do so too.
So, always use the 'staging' version:
http://arduino.esp8266.com/staging/package_esp8266com_index.json
This one works like a charm 'out of the box'.

Re: ESP8266 and Emoncms
Just as a matter of interest, has anyone got eMonLib working with an ESP8266?
I know they only have one ADC, so could only be used for monitoring current. However with the addition of an external analog mux it may be possible to read both voltage and current. I don't know how fast the ADC is on the ESP8266 (I can't seem to find a very good datasheet for this device), but if it was fast enough and the mux was fast enough, it may be possible to switch the mux and sample both voltage and current on the same ADC input.
Re: ESP8266 and Emoncms
Just for info:
I am now using the NodeMCU hardware (very convenient to use) in combination with the Arduino IDE. First project was to measure voltage and current of my PV storage battery and send this data via Wifi to EmonCMS running on a Raspberry Pi. I am using an external Microchip 18 bit I²C ADC (MCP3424 on Jeelabs Analog plug).
This is so simple, it is really amazing ....
BR, Jörg.
Re: ESP8266 and Emoncms
Hi Jorg,
I am interested in your NodeMCU implementation, this sounds very interesting! How are you sending the data to EmonCMS?
Jeff
Re: ESP8266 and Emoncms
+1 to that. Which version of emoncms and how have you linked the data into emoncms?
Must admit I've also found it incredibly easy to get things up and running with the arduino ide. I've been using Nathan Chantrell's dev board with the esp03, sending temperatures to an mqtt server.
For anyone wanting to play around you could also look at the simple web server demo that Pete Scargill published in the last couple of days.
Simon
Re: ESP8266 and Emoncms
Jeff, Simon,
I use the NodeMCU hardware with the normal 'Arduino' firmware.
Attched my small sketch. It reads voltage and current from an MCP3424 and sends this data to the EmonCMS running on a Raspberry Pi. (Wifi and EmonCMS keys deleted).
Hope it helps.
BR, Jörg.
Re: ESP8266 and Emoncms
I am hoping to use some ESP8266 devices on my home automation. The first project is to use one with a DHT22 to report temperature and humidity back to emoncms.
In fact, where I can I will use an ESP8266 instead of an Arduino. They have limited cpacity but for simple tasks where an Arduino isn't needed they are perfect.
The general principle I am hoping to use on my home network is to expose sensor data from an ESP8266 as json or a simple web page. The ESP8266 acts as a simple web server very easily so creating a kinda API for other nodes on the Wifi network to interrogate should be straightforward.
Re: ESP8266 and Emoncms
Thank you Jorge! Your code cleared up some mysteries for me.
Re: ESP8266 and Emoncms
Jorge. Much appreciated!!
Just an FYI, you missed blanking one of the api keys. There is one at the end of the code. You might want to blank this and resubmit.
But very many thanks, this has really helped me. Would have taken hours of searching for the info and debugging it until it was running.
Simon.
Re: ESP8266 and Emoncms
Simon,
oh yes, missed that apikey (I had made a test with variable and 'hard coded' strings). Not a big issue though as the Raspi is on my internal network only. Would have been worse if I had published my WIFI key ;-)))
When I wrote that sketch I had just begun to play around with the Arduino ESP8266. There might be places in the code where things can be done in a better way. But this setup is running since some weeks now without any problems. It is reading the voltage and current of my PV storage battery. Next amendment will be to read the charge and discharge currents separately with two individual shunts (battery is charged via an MPPT charge controller and discharged by a controllable AEconversion grid tie inverter). And then I want to add an RS485 for communication with the inverter. The software changes will be easy, it takes more time to do the hardware part.
BR, Jörg.
Re: ESP8266 and Emoncms
I have been using an ESP8266 with an ADS1115 ADC to read data off a current clamp and approximately monitor my power usage. Here is the set-up:
There is a free differential channel for reading the voltage using a transformer as well.
Re: ESP8266 and Emoncms
Which ESP8266 board you are using?
Do you have a circuit diagram for this?
What code are you using?
Re: ESP8266 and Emoncms
I am using a NodeMCU v1.0 board like this one - https://github.com/nodemcu/nodemcu-devkit-v1.0 . It is slim and fits nicely on the breadboard. The ADS1115 is attached to pins 1,2 of the NodeMCU via the I2C bus. The code I am using is a modified version of the Irms method in emonLib for Arduino. I will upload my sketch to gist tonight and update this.
Re: ESP8266 and Emoncms
Here is the gist with the code - https://gist.github.com/whatnick/73c244694466355f6a14
Re: ESP8266 and Emoncms
Thanks.
With the ADS1115, would it be able to monitor a total of 4 currents since it is a four channel system?
Re: ESP8266 and Emoncms
I am using the ADS1115 in differential mode to avoid having to add the bias voltage resistors and have a voltage reference. So my set-up is limited to 2 channels. You have the choice of setting it up in single ended mode with voltage dividers and using all the 4 channels separately, or you can put 2 ADS1115 sensors on the I2C bus with different addresses as shown here. I am going to get Fritzing and redraw this with Node MCU.
Here is how the ADS1115 is connected to the NodeMCU:
Re: ESP8266 and Emoncms
Thanks for all the information.
Re: ESP8266 and Emoncms
I have put my project together on a PCB and it is available here - https://www.tindie.com/products/whatnick/nodemcu-energy-monitor-pcbkit/ . Please let me know if you are interested.

Re: ESP8266 and Emoncms
You are publishing your api key...
look:
client.print("GET /emoncms/input/post.json?apikey=b53ec1abe610************9e&node=20&csv=");
correct it if you can
Re: ESP8266 and Emoncms
Here's firmware for ESP8266/EmonCMS code I wrote to get data from an Electric Vehicle charging station and send it to the server.
https://github.com/chris1howell/OpenEVSE_RAPI_WiFi_ESP8266
The firmware boots up as an Access Point in configuration mode to enter SSID, Password, EMON Key and Node which is stores in EEPROM.
Then it boots into client mode, connects to your AP and sends data to EmonCMS. The web server is active in client mode to edit configuration.

American Pie Director: Paul Weitz; Screenwriter: Adam Herz Country: USA; Year: 1999 Rating (4 star system): *
I like comedy. Who doesn't? I'm sure there are those who don't, but I have yet to meet them. Comedy, at its best, reflects our culture. But it does not merely reflect it for observation. Great comedy can make insights into culture in ways that make us realize not only how we are, but also how we should be. Great comedy makes profound observations so that we can possibly make profound insights. Great comedy makes one think. American Pie may be the furthest thing from profundity that I have yet seen onscreen. Sure, many of the characterizations are pretty good; unfortunately, characters in the film reminded me of some people I went to high school with, but I learned nothing new from seeing them portrayed onscreen. That is, unless you count the "insight" that teenagers are apparently obsessed with sex among profound realizations. Obviously, I do not. So many films have already treaded this water, that it seems amazing that no one has yet drowned in their wake. For some reason, these films continue to make money. I suppose they are reaching an audience, but it is apparently not an audience of which I am a part. I will avoid calling the humor in this film "gross-out" humor as so many already have. Instead, I will call it "gag humor." The film is simply a series of gags that, while obviously related through their teenage angst and sexual content, fail to coalesce in any way to speak about anything. At no point did I learn anything new from the seemingly endless stream of gags. The question now raised may be, "does a series of gags necessarily need to answer some larger question or make some unique statement?" And while I believe any film that achieves this has all the greater potential to be a great film, I do believe a film can be great without doing so. Gag humor is obviously nothing new. I tend to think of a number of silent films that relied on numerous gags, and even a number of these were great films without making a profound statement. Why, then, were these films great? Probably because they were great exercises in storytelling and cinema. This brings us back to American Pie and its qualities as cinema (or lack thereof). First of all, the screenplay was horrendous. Perhaps the only film I have seen so far this year that is more trite would be The Mummy. Every joke was so obvious and repetitive that, by the time the credits rolled, I felt as if I'd already seen the film half a dozen times [and perhaps I have with different actors and titles]. Those jokes that did somehow seem relatively new relied, for the most part, on shock value, which means it's really only funny once or twice if at all. Even if I had enjoyed the film the first time, I'm sure that I would enjoy it less and less every time I re-screened it. Perhaps not all can be blamed on the writing. Most of the acting was pretty bad as well. None of the cast really seemed very natural. It all seemed forced. Again, this goes back to the situations involved in the screenplay, but the acting only magnified the feeling. Some of the acting was, of course, better than the rest- most notable would be Chris Klein as Oz, the jock of the group. Between this film and Election, I would say he is one to watch. He just needs to choose the right breakthrough. Alyson Hannigan as Michelle, the flute-toting band geek, provided the only moments where I really laughed at all through the whole film, but it still remains to be seen whether any more should be expected from her. Jason Biggs as Jim, the most desperate of the group, was merely watchable, as was SCTV alum, Eugene Levy, as his father, and the rest of the cast was either throw-away or unwatchable. As for the direction, not much can really be said. Why is this? Basically because there was none. It was as unnoticeable as it was useless. This is hardly the first film to rely on gross-out humor [err.... I mean gag humor], but unlike films such as last year's There's Something About Mary (which I enjoyed to some extent), this film was a useless exercise in mindless "entertainment." It remains to be seen what the lasting value of films such as the aforementioned Mary will be, but they seemed to at least make some sort of effort at being new and well-crafted. American Pie seems to be more fleeting than any film I have seen... Or maybe I should say "remember" as I have forgotten those films I'm sure I've seen that were somehow more fleeting than this.

* unspeakable desolation pouring down from the stars *
CHAPTER SEVEN
THE NIGHT SKY WAS splattered with stars. I was halfway across a beetroot field, swinging my arms and following my nose, when I remembered that I had left my haversack in the cloakroom of the Spangles Reference Library. The journey to the HQ from the owl sanctuary had taken three days, as far as I had been able to tell. The special agent had mentioned something about a forty mile stretch: but he was a crafty devil. For all I knew the HQ may have been just around the corner.
But I seemed to be in open country, and the night was pitch black save for the twinkling stars. A town like Spangles would surely be lit up at night by festive lanterns: it was that sort of place. I had no choice but to continue striding ahead. By morning, I thought, I should reach some sort of landmark: a town or village, a crag or a promontory, a windmill, a tower or a tor.
As I plunged through the darkness, I kept the image of the philatelist Plunkett in the forefront of my brain. I knew where he lived, of course: I knew everything about him, as I had been demonstrating to the Turquoise Badge Ten. Plunkett Hall was a strangely proportioned brickish monstrosity, perched on a clifftop on the wildest shores of the Soaking Wet Sea. Curious passers-by, who were few, were warned by a sign bolted to the massive granite wall surrounding the landward sides of the house that Trespassers Will Be Fed To The Vultures. The house had few windows, and those few were tiny, mere narrow slits of smoke-blackened glass. Ferocious, cloven-hooved beasts, their fur matted and rank, their fangs dripping with gore, patrolled the grounds, howling and howling. Once a month, one of the philatelist's eerie servants would issue forth from the house armed with a flamethrower, and incinerate any poor sprig of greenery which had managed to grow in the blasted wastelands of the garden. Plunkett himself was rumoured never to have set foot outside the house since he had retired to it twenty years before. How he passed his days, none knew: the handful of biographies I had read all petered out with his arrival at the house. Plodding onward, I shuddered at the thought that, once I had retrieved my haversack, my mission impelled me towards that cursed place. I had no wish to provide dinner for a bale of vultures, so I would need to think up a convincing excuse to enter Plunkett Hall as a legitimate visitor.
If only Fig were with me now, I thought, and as I did so I tripped over a clump of bracken and fell to the ground, jolting my ribcage and spraining my wrist. The night seemed more suffocating than ever: unspeakable desolation poured down from the stars. I sat down on a tuffet and burst into tears.
I do not know for how long I wept. I was engulfed by a nameless and terrible grief. My body was wracked by great heaving sobs which emptied my lungs and had me scrabbling in the earth as if trying to effect my own burial. Hours and hours seemed to pass, but there was no glimmer of dawn. I imagined myself marooned in an endless and illimitable night. At the very peak of my misery, as I drew my head up to bay woe, woe and woe at the sky, I was startled to see a figure in the distance, moving towards me. It was spectral and wraith-like, shimmering with an uncanny glow. I stood up, exhausted but now alert, tingling with wonderment. The spectre approached with inhuman speed, and within seconds came to a halt inches from my face. I squinted at it through the last drops of my tears. It looked something like a combination of Fig and Poxhaven: but then it spoke, and it sounded like my dead headmaster, Monsignor Sinkpail.
"Here is your satchel," it said, handing me my haversack. However unearthly the apparition before me, there was no doubting the weight and solidity of the haversack: I didn't remember it being so heavy. I rested it on the ground.
"Your satchel is a heavy burden," said the spectre, "I have carried it many miles. I have brought it to you from its locker, out of the library, past the baths, the chemist's shop, the Town Hall, the pigeon lofts and the owl sanctuary, along Blister Lane, turning right at the duckpond, then up Pang Hill until I reached the waterworks, where I struck off down Amnesiac Lane towards the graveyard, hopped over three fences and headed west to Bodger's Spinney, where I dipped my cup in the stream and rested awhile. Using my internal compass, I then made my way to a mysterious village, where the dandelions are blue and the air is thick with the stench of vinegar. I dithered in the square, and was at a loss until I espied a little news-vendor's kiosk, where I was able to obtain a gazetteer of the village and its hinterland, which I studied carefully until sunset. I slept there, uncomfortably, on the plastic roof of the kiosk. When morning came, consulting the gazetteer, I whisked myself along the towpath of the canal, crossing it at Sawdust Bridge and following thereafter the course of the Great Frightening River. I camped on the knoll. The remains of your sausage gave me sustenance. There are many butterflies to be found there: I netted and ate half a dozen of them. By now your satchel was weighing me down. I hared on, past the fireworks factory and the dental institution, and found myself in a thicket of nettles. I inched my way through it with the aid of my secateurs. Then I caught the funicular railway up to the top of Pilgarlic Hill, and hurried down the other side on foot, splashing through puddles, until I reached the pig farmer's house. I hid in his orchard and snoozed, until the pig farmer set his hounds on me: I was able to escape from them by spraying their snouts with a concoction of bleach and aniseed, but not before they had bitten mouthfuls of fabric from my spectral trousers. From there, I strode with giant steps across fields of barley, turnips, bracken, furze and javelin weed, past an abandoned quarry, and on through a knot of allotments, where again I rested, finding shelter in a hut empty but for the broken and rusted remnants of a lawnmower, the skull of a badger, and a tattered instruction manual. What the instructions were for, I do not know: I cannot read. I dozed, begged a bottle of lemonade from an early-bird allotmenteer, and trudged towards the west, skirting the Shabby lime-kilns and the serried belvederes of Haemoglobin Towers, until, night crashing down again, I hit upon this astonishingly large tract of beetroot fields, where at last I have found you. My task is almost done. It remains for you to lodge what I have just said in your brain, and for me to bid you farewell with the words which, if you say them with sufficient conviction, will gain you entrance to Plunkett Hall. You must knock at the gate, and wait, and wait, and when, at last, one of Mr Plunkett's servants opens the little shutter three feet above your head, and, in fearsome, gravelly tones, bids you state your business, you must say: hello, I've come about the tap. My deed is done. Farewell."
The spectre did a little hop, and dissolved.
Well! It might as well have given me a map. Mentally following the journey it had described, I realised just where I was. The world remained enwrapped in night, and I was once more alone, but my spirits were lifted immensely. I had got my bearings: I was no more than half an hour's walk from Plunkett Hall. I resolved, when dawn should break, to head straight there, to say the given words, and, once inside, to play it, as they say, by ear.
For the time being, squatting on the tuffet, I threw open my haversack to inspect its contents. I was pleased to note that all the items Scrimgeour had so carefully packed were undisturbed and still intact. I could not account for the fact that they had been padded out with numerous grey sacks filled with waterlogged sand, but I decided not to dizzy my poor brain by puzzling over such inexplicable phenomena: I simply removed the sacks one by one, placing them carefully to one side in the channels between the rows of blooming beetroot.
Before moving on to the next part of the story, it would probably be appropriate for me to indulge in some speculation about the provenance of the spectre: but I will not do so.

--- layout: post authors: ["Greg Wilson"] title: "All I Want for Christmas is a Pull Request..." date: 2014-12-18 time: "06:00:00" tags: ["Lessons"] ---
As we said back in October, we're splitting the existing lesson repository into smaller and more manageable pieces. To do that, we have defined a new template for lessons, and have been extracting the history of the existing material from the current repository. (We wanted to get the entire history of each lesson so that people would receive credit for the work they've done.) The second step has taken longer than planned, but we now have all of the core novice lessons in repositories of their own:
There's still a lot to be done:
The CSS used to style the new template needs a major overhaul.
The validation tool used to check the format of lessons against the new template needs more work.
The challenge exercises all need titles (right now, most are titled "FIXME").
We need a 3-minute motivational slide deck for each lesson. (See this page for a preview of the tool we're going to use to record these.)
Glossary entries need to be brought over from the old repository.
The intermediate lessons need to be extracted from the old repository and merged with the new lesson template.
Learning objectives for each lesson need to be rewritten to be more concrete.
Data files in
the novice R lesson
need to be
moved into the data
sub-directory
and paths in the source updated accordingly.
The outstanding pull requests
against the master
branch of the shell lesson need to be merged or discarded
so that we can close that branch and start doing everything against gh-pages
.
The "images" produced by ipythonblocks in the novice Python lesson need to be regenerated as PNGs (rather than as HTML tables), saved, and linked in.
...and a hundred and one other things, because lessons are like theses: they're never done, they're just delivered.
One thing you'll notice is that we're now using Markdown for everything instead of IPython Notebooks. We still teach with notebooks when we're in front of a class, but our contributors have found diffing and merging them difficult enough that we're switching back to plain old text for the notes until something like nbdiff is ready for prime time.
Another thing you might notice is a new capstone lesson showing people how to use the shell, Python, SQL, and Git to extract authors' names from a bibliography stored in a spreadsheet and answer questions like, "Who has co-authored papers with whom?" This lesson is meant to be useful in its own right, but also to serve as an example for others of its kind. If you have something short and accessible that you'd like to share, please let us know: we'd be happy to work with you to bring it to a wider audience.
What we need most, though, is polish: all of the points listed above need to be addressed before we can put these lessons on the website instead of the ones stored in the old repository. If you have 15 minutes, please dive into one of these lessons, proof-read one section, and file some issues. Or better yet, send us a pull request that fixes something—anything at all—so that we can hit the ground running in 2015.

Collections Class
The Collections class implements static methods useful when
writing a class that implements Collection
and the iterator
method.
Static Methods
Code String collectionToString(Collection c) #
Returns a string representing the specified collection. If the
collection is a List
, the returned string looks like this:
'[element0, element1, ... elementN]'
. The value returned by its
toString
method is used to represent each element. If the specified
collection is not a list, the returned string looks like this:
{element0, element1, ... elementN}
. In other words, the strings
returned for lists are surrounded by square brackets, while the strings
returned for other collections are surrounded by curly braces.
If the specified collection contains a reference to itself, either
directly or indirectly through other collections or maps, the contained
reference is rendered as '[...]'
if it is a list, or '{...}'
if
it is not. This prevents the infinite regress that would otherwise occur.
So, for example, calling this method on a list whose sole element is a
reference to itself would return '[[...]]'
.
A typical implementation of a collection's toString
method will
simply return the results of this method applied to the collection.
static String collectionToString(Collection c) { var result = new StringBuffer(); _emitCollection(c, result, new List()); return result.toString(); }
Code bool every(Iterable iterable, bool f(o)) #
static bool every(Iterable iterable, bool f(o)) { for (final e in iterable) { if (!f(e)) return false; } return true; }
Code List filter(Iterable source, List destination, bool f(o)) #
static List filter(Iterable source, List destination, bool f(o)) { for (final e in source) { if (f(e)) destination.add(e); } return destination; }
Code void forEach(Iterable iterable, void f(o)) #
static void forEach(Iterable iterable, void f(o)) { for (final e in iterable) { f(e); } }
Code bool isEmpty(Iterable iterable) #
static bool isEmpty(Iterable iterable) { return !iterable.iterator().hasNext(); }
