THE REMAINS OF THE DAY A film review by Alex Lopez-Ortiz Copyright 1993 Alex Lopez-Ortiz
Starring: Anthony Hopkins, Emma Thompson, James Fox, Christopher Reeve Screenplay: Ruth Prawer Jhabvala based on the novel by Kazuo Ishiguro Director: James Ivory
THE REMAINS OF THE DAY is a movie about rhythm. The plot, the performances, the photography, the characters are all about rhythm.
Is REMAINS then a musical? Not at all. Read on!

Those movies are based in their fast paced action or as I call it, on their fast rhythm. The plot is minimal, they have mostly no character development--beyond the fact that the hero is good and the villains are bad, that is--and almost no message, again, excluding the traditional "good always wins."
Those are the rock songs of the big screen.
THE REMAINS OF THE DAY is a classical symphony.
Well-paced, soft, musical, Anthony Hopkins sets, with his presence, the cadences in this film.
Miss Kenton, Lord Darlington, and Mr Lewis are all musical instruments, playing to the tempo set by the director of the Orchestra, Mr Stevens. The musicality of the movie is magnificent and thoroughly enjoyable.
As with action movies, the plot is tangential, even superficial. Anybody who thinks of Great Britain's version of Plato's educated elite as a bunch of amateurs, needs to review its junior high history lessons.
The rest of THE REMAINS OF THE DAY's "insights" on English society are not much deeper than this. Even the central premise of the movie is vacuous. Englishmen would be a race long extinct if their stiff-upper-lipness were an impediment for establishing relationships. The criticisms of Mr Stevens' extreme devotion to his work cannot be anything but self-criticisms of Japanese's own devotion to work. (Recall that the author of the novel, upon which the movie is based, was written by Kazuo Ishiguro from Japan).
Nevertheless, the absence of a plot did not stop me from recommending TERMINATOR 2, and it certainly won't either with THE REMAINS OF THE DAY.
All to the contrary, THE REMAINS OF THE DAY is an excellent movie, and Anthony Hopkins performance is superb. Casting choices were most appropriate. Little can be criticized in this movie. THE REMAINS OF THE DAY is definitely in my short list for best movie of the year.
Rating: 9 out of 10

This is the perfect indulgent breakfast. Home-made hollandaise sauce is much easier to prepare than you may think and beats any kind of shop-bought variety hands down.
Fill a small pan just over one third full with cold water and bring it to the boil. Add the vinegar and reduce to a simmer. Crack the eggs one at a time into a small bowl and gently tip into the simmering water. Poach for 2-3 minutes. Remove with a slotted spoon and plunge into iced water, then remove the eggs and place them on a kitchen towel.
For the hollandaise sauce, melt the butter slowly in a medium pan over a low heat, stirring occasionally. Remove from the heat and pour the butter into a jug. Add enough water into a medium saucepan to come a third of the way up the sides. Bring to the boil, then reduce the heat to a simmer.
Put the vinegar, shallot, peppercorns and bay leaf in a small saucepan over a high heat and bring to the boil. Cook for 1-2 minutes, or until reduced to two tablespoons of liquid. Remove from the heat.
Put the egg yolks in a heatproof bowl and place over the pan of simmering water. Whisk the egg yolks with the salt and sugar until pale. Pour the vinegar mixture through a fine sieve onto the yolks and continue whisking until well combined. Slowly add the butter in a steady stream whisking constantly until the sauce is smooth, thick and shiny.
Toast the muffin halves and bring the pan of water back to a simmer, ready to reheat the eggs.
Spread the muffins with butter. Put a muffin half on each plate and top with ham or salmon. Using a slotted spoon, drop the cooked eggs in to the simmering water and reheat for one minute. Remove and drain on kitchen paper.
Place an egg on each muffin and spoon over some hollandaise. Sprinkle with chives and serve with the other muffin halves on the side.


ABOUT ME
AMAN
DODD
Hi, I’m Aman, a 19-year old developer in my second year of Computer Science at the University of Waterloo. I’m currently skilled in Java, C++, HTML, CSS, and Javascript. Furthermore, I’ve always liked to classify myself as a continuous learner; someone who’s always searching to surpass the personal knowledge boundaries and learn more.
To me, life as a whole is an investment in a process of finding your niche, your passion, and I can rightfully say I was a late-bloomer in that category. Prior to being in CS, I partook in two years of Mechanical Engineering (if you haven’t noticed already), before making the move over to CS. It wasn't so I hated Mechanical Engineering, it was more so the potential and growth I saw in myself, which I believe could only be fulfilled in a path of passion which for me was Computer Science; a field not only which I enjoyed immensely, but one that is growing hastily.
Ready to start your next project with us? That's great! Give us a call or send us an email and we will get back to you as soon as possible!

Digital arcade booths let players become part of classic games including Pacman
A new ‘hyper-immersive’ gaming experience has opened in London, where players become part of classic games, including Pacman and Brick Breaker
by Shivali Best, https://www.facebook.com/shivalibestjournalist/From virtual reality to high-definition displays, gaming technology has come on leaps and bounds in recent years.
Now, a new ‘hyper-immersive’ gaming experience has opened in London, where players become part of classic games, including Pacman and Brick Breaker.
The experience, called Electronic Theatre’s LightBox, sees players don visors, each with a unique antenna on it, before entering a small square room.
While the room seems pretty bare, cleverly-placed projectors quickly transform the walls into motion-sensing touch screens.
Teams of up to six are then put through a series of interactive games and challenges, ranging from memory tests to agility training.
The unique antennas on the visors allow the room to track the position of each player, meaning games can be controlled by physically moving around the space.
For example, during a Brick Breaker game, each player becomes a paddle, and must run up and down the room to bounce the ball up towards the bricks.
Meanwhile, during Pacman, players take it turns to run around the room to collect coins, while avoiding the ghost.
Will Dean, founder and CEO of Electronic Theatre, said: “Electronic Theatre is an experience that any group - be they friends, family, or work-mates can complete and feel a bit closer to each other.
“Creating shared memories bonds groups like nothing else. By completing one of our Adventures, teams will create a memory they can look back on together”.
The first site is located on London’s Southbank, and is open to the public now.

a flashy-light trippy thing
The plan is to make a personal version of the Dreamachine, a "stroboscopic flickering light art device that produces eidetic visual stimuli".
It has sunglasses-mounted LEDs, audio output for headphones (TODO), with two rotary encoders and a tiny LCD display for control. It will have audio output for headphones, providing modulated white/pink noise.
The device is being built around the ESP32 microcontroller module, hardware currently on a breadboard. For software development I'm using PlatformIO (on VSCode on Ubuntu).
I'm organising notes as I go along, the raw material is in devlog.md, wiring in wiring.md, parts list in components.md.
2022-09-03 Hardware (mostly) done on breadboard, hard parts of the software (concurrency bits), documentation nearly up-to-date.
Detailed status is in devlog.md.

QGIS
$\Rightarrow$ For the ease of use of Python (for replication), we will learn ArcGIS
R
Purchasing ArcGIS
License fee (in case of Japan): 18,000 yen per year
Make sure the package you buy include:
1. Show file extensions (.shp
etc) in File Explorer
2. Install 7-Zip for 64-bit Windows
.tar
files
1. Launch ArcMap 10 (it takes time)
2. Download the zipped dataset for lecture 1
3. Save it to Desktop (C:\\Users\\yourname\\Desktop
)
4. Right-click it and choose 7-Zip > Extract to "Lecture1\"
C:\\Users\\yourname\\Desktop\\Lecture1
Browse the inside of the Lecture1
folder
I've created 4 folders:
code/
: files to edit datasets (e.g. Python scripts)
input/
: original data
output/
: final data to be used for analysis
temporary/
: other files created during process
It's a standard directory structure to organize files for empirical analysis
Now browse the input/
folder
5. Right-click all the .zip files and select 7-Zip > Extract Here
10m-rivers-lake-centerlines.zip
gadm36.zip
glds90ag.zip
Leave F162008.v4.tar
(nighttime light raster)
for the time being.
Spatial data comes in two different formats
How to edit data differs a lot between them
We now learn how to browse spatial datasets in ArcGIS while learning these different formats of spatial data
Each spatial unit in vector data is called a feature
Three types of a feature:
A set of features of the same type: a feature class
File format: Shapefile (.shp)
Represent geographic zones
Data to be read: GADM (widely used by economists)
gadm36/gadm36_0.shp
(countries)
gadm36/gadm36_2.shp
(subnational districts)
Drag these files in Catalog Window to Data Frame
If you don't see Catalog Window...
$\Rightarrow$ Click Windows in the menu bar
If you don't see the data directory in Catalogue Window...
$\Rightarrow$ Right-click Folder Connections and click Connect To Folder...
Represent networks / routes
Data to be read: Natural Earth's Rivers and Lake Centerlines data (10m_rivers_lake_centerlines.shp
)
Browse this data (cf. Exercise 1)
Uncheck the subnational boundary data in Table of Contents
$\Rightarrow$ Now rivers are shown on national boundaries.
Change the color of rivers to blue.
If you read the river data first and then the national boundary data, the river data would be hidden below the national boundary data.
If you cannot drag the data in the Table of Contents window, check if the List By Drawing Order icon is selected on top left.
Represent point location
Can easily be created from XY data
Each row: point feature
Column 1: longitude (x value)
Column 2: latitude (y value)
Other columns: attributes of point feature
1. GPS receivers
If you conduct your own survey
2. Online gazetteer
If location names are available, search at:
See Sundberg et al. (2010) for an example protocol
3. Geocoding tools
If postal address is available, use:
Data format: Comma-delimited text (csv) / Excel worksheet
export delimited
(Stata help)
Code example for 10 dicimal digits for longitude/latitude
format lon %15.10f
format lat %14.10f
export delimited lon lat using filename.csv, replace
To convert XY data into a point feature class, use:
These are the examples of geo-processing tools
Data to be read: CEPII GeoDist Database (geo_cepii.xls
)
Browse the data in Excel
To implement geo-processing tools, we use Model Builder
XY Table: input/geo_cepii.xls/geo_cepii$
X Field: lon
Y Field: lat
Spatial Reference: WGS 1984
If you don't know what to fill in on the geo-processing tool window:
This tool creates a temporary layer
But the layer often doesn't properly work with other tools
We also want to save the point feature class in the disk
$\Rightarrow$ Always use the Copy Features tool to convert the layer into a shapefile data
Input Features: the output from the Make XY Event Layer
Output Feature Class: ...\Desktop\Lecture1\output\cities.shp
Ignore other options. Rarely used.
Also useful if you want to keep the original data intact
To save the model:
code/
)
lec1.tbx
)
exercise3
)
A model can only be saved inside the toolbox.
Save frequently; ArcGIS often crashes.
To edit an existing model:
Now run the Model by clicking the triangle icon at top right
Browse the output point feature shapefile
Capital cities (and other major cities) around the world should appear as point features.
One more thing about vector data...
Contains fields (i.e. variables) which can take a different value for each feature
To browse in ArcMap:
Spatial data comes in two different formats
How to edit data differs a lot between them
Divides the earth surface into many "square" cells (or pixels)
Each cell contains one value
Often created from satellite images
Examples:
Can create a new variable for vector data (Lecture 5, 6, 8)
Most file formats can be browsed in ArcMap
.tif
)
$\Rightarrow$ I recommend using TIFF format
For the ASCII format (.asc
), you need to convert it into TIFF (Excercise #5 below)
Data to be read: DMSP-OLS nighttime light for year 2008
F162008.v4.tar
.gz
and .tfw
files.
.gz
files to the same folder as .tfw
files
.tfw
file allows ArcMap to read a TIFF image of the same file name as geo-referenced (see Greenberg 2003 for detail)
F162008.v4b_web.stable_lights.avg_vis.tif
Data to be read: population density in 1990 (input/glds90ag.asc
)
Use the ASCII to Raster tool
output/popden90.tif
.tif
" to save in the TIFF formatWhen you read the converted population density raster, you'll get a pop-up alert message: "Unknown Spatial Reference"
We'll come back to this issue shortly.
Stata can read raster in the ASCII format, with ras2dta ado (Muller 2005)
Each cell becomes one row in Stata
To export raster as the ASCII format, use the Raster to ASCII tool in ArcGIS
NetCDF files: Widely used for time-series raster data
To browse NetCDF data at each point in time, use:
Earth is a sphere (approximately)
Various ways to two-dimensionally represent the earth surface
Each way corresponds to a coordinate system
aka. spatial reference / map projection
To calculate distance and surface area properly
To merge different spatial datasets accurately
cf. Apple Map did this wrong when it was launched in 2012
See Eubank (2018) for more exact explanation on the difference
Each location is coded by degrees
e.g. Osaka: 34.6937° North, 135.5022° East
Not suitable for calculating surface area
But useful for calculating distance between two locations
WGS 1984: most popular
Earth surface is projected by the "light" from the center of the earth on cylinder:
Earth surface is projected by the "light" from the center of the earth on cone:
Earth surface is projected by the "light" from the center of the earth on plane:
Each location: coded in meters from a certain origin
WGS 1984
UTM
Any equal area projections
Differ just in how the world is shown
Differ just in how the world is shown
Differ just in how the world is shown
Map Projections: A Working Manual, by John P. Snyder (U.S. Geological Survey, 1987) (Downloadable for free)
Project: for vector data
Project Raster: for raster data (Lecture 7)
Define Projection: if undefined (for both vector & raster)
Don't use Project (Coverage) or Define Projection (Coverage)
Spatial data usually comes with a meta data that specify the coordinate system used when the data is created
GPW's meta data says it's WGS 1984
Use Define Projection to assign WGS 1984 (cf. Exercise #3)
Note that this geo-processing tool overwrites the input file.
Suppose we are interested in calculating the surface area of districts around the world
Sinusoidal projection allows you to calculate surface area properly
Use the Project tool to change the coordinate system from WGS 1984
Sinusoidal projection is found at:
Projected Coordinate Systems > World > Sinusoidal(world)
Browse the output. Does it look like this?
You cannot overlay data with different coordinate systems
ArcMap displays data in the coordinate system of the data read first
To browse a data with a different coordinate system, open a new map document

Ever had uncomfortably hot beer and undrinkably cold coffee? Inspired by a guest lecture by Professor Brian Storey, fellow student, Hannah Wilk and I recreated his "magical coffee and beer heat exchanging machine" using a water bath and some common household materials. What ensued was a wet and slow recreation of a heat exchanger. Though our method would only cool both fluids to the same temperature, we had a fun sojourn into the thermodynamics of heat exchange.

News story
Details of changes to teachers' pay which came into force in September 2013.
New arrangements for teachers’ pay came into force in September 2013 and are included in the School Teachers’ Pay and Conditions Document ( STPCD ) 2013 . We have also published departmental advice on ‘Reviewing and revising your school’s approach to teachers’ pay’ to help schools and governors incorporate these changes into their own pay policies.
The main changes are:
By September 2013 schools should have reviewed and revised their pay and appraisal policies to:
Our model pay policy will help schools to review and revise their pay policy.
Schools can also refer to the appraisal regulations (The Education (School Teachers’ Appraisal) (England) Regulations 2012 or The School Teacher Appraisal (Wales) Regulations 2011) and the department’s model appraisal policy to rework their appraisal policy.
Governing bodies need to ensure that the appraisal and pay arrangements are transparent and appropriate and hold headteachers to account. To help governors carry out their role, the National College for Teaching and Leadership (NCTL) is offering training for around 2,500 governors between January and March 2014.
Maintained schools which do not implement the new system will be in breach of their legal duties. In addition, where schools do not use their staff budget to differentiate between good and poorer performing teachers, this could affect a school’s Ofsted rating for the quality of its leadership and management.
The first performance-based pay rises will be paid in September 2014, based on the appraisal cycle that began in September 2013.
It will be up to schools to decide how they link pay progression to appraisal and the criteria that they will employ, but we expect teachers to be judged against a range of criteria and their wider contribution to the work of the school, not purely on exam results.
The changes allow schools to pay teachers in line with their performance rather than every teacher progressing at the same rate. The most successful teachers will be able to progress faster.
Schools can also develop their own criteria for deciding when a qualified teacher deserves to move to the upper pay range. The new criteria for accessing the upper pay range are set out in the revised STPCD .

- info(object[, object, ...])
- The operation is similar to the .log(), but is made in a different design to distinguish the types of messages, for example, the importance of graduation or for other semantic meaning of this group of messages. Patterns are supported (described in .log()). An example of differences for Firebug, Chrome, IE9:
|
|
+ |
+ |
+ |
+ |
+ |
+ |
+ |
- log(object[, object, ...])
- Displays the arguments in the console, separated by spaces. The most popular command in console.
It supports patterns, which are special names in the first argument, indicating that it should be to use as template, in which following arguments will be substituted instead variables of pattern (as in printf() in C, but it is much easier). Examples:
(javascript)
console.log('Peter had %d %s', 10,'apples');
console.log('Pi is equal to %f', Math.PI);
console.log('%cRichard %cOf %cYork%c Gave Battle In Vain',
'color:red;','font-size:16px;color:orange;','background:black;color:yellow;',
'font:normal;color:normal;background:normal;');
console.log('body as DOM: %o',document.getElementsByTagName('body')[0]);
console.log('object: %O',{a:1,b:2});
console.log('body as Object: %O',document.getElementsByTagName('body')[0]);
Types of patterns and data type to which it converts values:
%s — string.
%d or %i — number.
%f — float number (Firebug supports also).
%o — DOM-element (Firebug outputs as reference to element. Chrome, in addition to references, displays an item in the console. Firefox opens in a modal window by click (all attributes and methods of this object are available)).
%O — JS object (not supported in Firefox; Chrome converts DOM object to JS object for this pattern; Firebug does not distinguish %o and %O).
%c — CSS-style (color, background, font; in Firefox is supported from version 31). Example of stylization by pattern %c (Firefox):

- table(data[, columns])
- The two-dimensional tabular data presented in a tabular format. Data is array or object (or object of objects, object of arrays), each element of which is a string in the table. The first column of a two-dimensional array will be its index (from 0). Or, if there is an object, the first column would consist of keys of the object. Example in Firefox (object of objects):
Columns is optional array of names of columns for the table header, if the strings are built from arrays, and we do not want to have the names of numeric codes. Above was an example of the result (Firefox), either obtained from the named column or object of objects. Below we show that it would be from an array of arrays without parameter columns:

I snorted half a pill, Im sorry I dont know how many milligrams it was, at around 2pm. The feeling was good, although nothing too intense. However, between 6 and 7pm I smoked some pot. Immediately I became very hot and had to step outside. Sitting outside in the 15 degree temperature, still very warm, I began halucitating. The visuals were very similar to a mushroom trip.
I then managed to climb up some stairs on my college campus. However, I fell down these stairs and lostcontrol over my body. My mind was still present and I was aware I was falling. I came to having fallen down half the set of stairs, only to black out again and fall down the rest.
I was more than pleased with what the drug had done to me, namely because of its intensity and I began to come down around 9 or 10 pm. However, the next day, I woke up with a rash on the undersides of my arms. The rash only increased in the coming days. It appeared on my midsection and slowing migrated up my chest and neck. I also had the rash on the palms of my hands and the soles of my feet. Showering burned intensly.
The rash was bad, but I also experienced serious respatory difficulty. I couldnt walk up stairs without being seriously out of breath. I would need to rest while standing in front of the refrigerator picking out something to eat. Eating also was not something I was able to do for a very long time.
More than a week later, with the rash still going strong and the respitory problems continuing, I ended up going to the doctor.  The steroids reduced the rash and breathing difficulty and got my appetite back. Two weeks after taking the morphine, the rash was gone.
Oddly enough, I had taken codeine and I have smoked lots of opium since that time and have experienced no side effects. I have been told that I may have been alergic to whatever else was in the pill, however, all of the symptoms I displayed were similar to allergic reaction to morphine. Be careful.

Hello World!
Today we are going to connect Power Bi to a SQLite database using Python.
There are usually 2 ways to connect:
• ODBC
• Python
ODBC requires you to setup the ODBC drivers for sqlite, which you can find here.
Doing this in Python is pretty easy, becaus Python has a standard library to read and edit SQLite databases.
Let's start coding:
SQLite Connection
import pandas as pd
conn = sqlite3.connect("PATH TO YOUR DB")
df = pd.read_sql_query("SELECT * from TABLE", conn)
Now we have a connection to the table that we can edit by using Power Query.
That's all for today.

and added to a collection, the index will use the function
implemented by the Quantizer
to generate keys against which it will store objects in the index.
Subsequently, when an index receives a query, it will use the same quantizer to determine from sought values
in the query the relevant keys against which it can find matching objects in the index. Given that the set of objects
stored against a quantized key will be larger than those actually sought in the query, the index will then
filter objects in the retrieved set on-the-fly to those actually matching the query.
As such quantization allows the size of indexes to be reduced but trades it for additional CPU overhead in filtering
retrieved objects.| Modifier and Type | Method and Description |

Warning
These instructions involve parts of the Azure command line that are in preview, hence the following documentation is subject to change.
You can create a Kubernetes cluster either through the Azure portal website, or using the Azure command line tools.
This page describes the commands required to setup a Kubernetes cluster using the command line. If you prefer to use the Azure portal see the Azure Kubernetes Service quickstart.
Prepare your Azure shell environment. You have two options, one is to use the Azure interactive shell, the other is to install the Azure command-line tools locally. Instructions for each are below.
Using the Azure interactive shell. The Azure Portal contains an interactive shell that you can use to communicate with your Kubernetes cluster. To access this shell, go to portal.azure.com and click on the button below.
Note If you get errors like could not retrieve token from local cache, try refreshing your browser window. The first time you do this, you’ll be asked to create a storage account where your shell filesystem will live.
Note
If you get errors like could not retrieve token from local cache, try refreshing your browser window.
could not retrieve token from local cache
The first time you do this, you’ll be asked to create a storage account where your shell filesystem will live.
Install command-line tools locally. You can access the Azure CLI via a package that you can install locally.
To do so, first follow the installation instructions in the Azure documentation. Then run the following command to connect your local CLI with your account:
az login
You’ll need to open a browser and follow the instructions in your terminal to log in.
Activate the correct subscription. Azure uses the concept of subscriptions to manage spending. You can get a list of subscriptions your account has access to by running:
az account list --refresh --output table
Pick the subscription you want to use for creating the cluster, and set that as your default. If you only have one subscription you can ignore this step.
az account set --subscription <YOUR-CHOSEN-SUBSCRIPTION-NAME>
Setup the CLI for Autoscaling features. First install the aks-preview CLI extension. This will grant access to new commands.
az extension add --name aks-preview
We then need to register the scale set feature.
az feature register --name VMSSPreview --namespace Microsoft.ContainerService
A VMSS is a Virtual Machine Scale Set, that is to say an autoscalable set of virtual machines.
The previous command will take a while to register. Use the following command to check it’s status.
az feature list \ --output table \ --query "[?contains(name, 'Microsoft.ContainerService/VMSSPreview')].{Name:name,State:properties.state}"
Once the VMSSPreview feature has been registered, refresh the registration with the following command.
az provider register --namespace Microsoft.ContainerService
Create a resource group. Azure uses the concept of resource groups to group related resources together. We need to create a resource group in a given data center location. We will create computational resources within this resource group.
az group create \ --name=<RESOURCE-GROUP-NAME> \ --location=<LOCATION> \ --output table
where:
--name specifies the name of your resource group. We recommend using something that uniquely identifies this hub. For example, if you are creating a resource group for UC Berkeley’s 2018 Spring Data100 Course, you may give it a <RESOURCE-GROUP-NAME> of ucb_2018sp_data100_hub.
--name
<RESOURCE-GROUP-NAME>
ucb_2018sp_data100_hub
--location specifies the location of the data center you want your resource to be in. For options, see the Azure list of locations that support AKS.
--location
--output table specifies that the output should be in human readable format, rather than the default JSON output. We shall use this with most commands when executing them by hand.
--output table
Consider setting a cloud budget for your Azure account in order to make sure you don’t accidentally spend more than you wish to.
Choose a cluster name.
In the following steps we’ll run commands that ask you to input a cluster name. We recommend using something descriptive and short. We’ll refer to this as <CLUSTER-NAME> for the remainder of this section.
<CLUSTER-NAME>
The next step will create a few files on your filesystem, so first create a folder in which these files will go. We recommend giving it the same name as your cluster:
mkdir <CLUSTER-NAME> cd <CLUSTER-NAME>
Create an ssh key to secure your cluster.
ssh-keygen -f ssh-key-<CLUSTER-NAME>
It will prompt you to add a password, which you can leave empty if you wish. This will create a public key named ssh-key-<CLUSTER-NAME>.pub and a private key named ssh-key-<CLUSTER-NAME>. Make sure both go into the folder we created earlier, and keep both of them safe!
ssh-key-<CLUSTER-NAME>.pub
ssh-key-<CLUSTER-NAME>
This command will also print out something to your terminal screen. You don’t need to do anything with this text.
Create a virtual network and sub-network.
Kubernetes does not by default come with a controller that enforces networkpolicy resources. networkpolicy resources are important as they define how Kubernetes pods can securely communicate with one another and the outside sources, for example, the internet.
networkpolicy
To enable this in Azure, we must first create a Virtual Network with Azure’s own network policies enabled.
This section of the documentation is following the Microsoft Azure tutorial on creating an AKS cluster and enabling network policy, which includes information on using Calico network policies.
az network vnet create \ --resource-group <RESOURCE-GROUP-NAME> \ --name <VNET-NAME> \ --address-prefixes <IP_ADDRESS>/8 \ --subnet-name <SUBNET-NAME> \ --subnet-prefix <IP_ADDRESS>/16
--resource-group is the ResourceGroup you created
--resource-group
--name is the name you want to assign to your virtual network, for example, hub-vnet
hub-vnet
--address-prefixes are the IP address prefixes for your virtual network
--address-prefixes
--subnet-name is your desired name for your subnet, for example, hub-subnet
--subnet-name
hub-subnet
--subnet-prefixes are the IP address prefixes in CIDR format for the subnet
--subnet-prefixes
We will now retrieve the application IDs of the VNet and subnet we just created and save them to bash variables.
VNET_ID=$(az network vnet show \ --resource-group <RESOURCE-GROUP-NAME> \ --name <VNET-NAME> \ --query id \ --output tsv) SUBNET_ID=$(az network vnet subnet show \ --resource-group <RESOURCE-GROUP-NAME> \ --vnet-name <VNET-NAME> \ --name <SUBNET-NAME> \ --query id \ --output tsv)
We will create an Azure Active Directory (Azure AD) service principal for use with the cluster, and assign the Contributor role for use with the VNet. Make sure SERVICE-PRINCIPAL-NAME is something recognisable, for example, binderhub-sp.
SERVICE-PRINCIPAL-NAME
binderhub-sp
SP_PASSWD=$(az ad sp create-for-rbac \ --name <SERVICE-PRINCIPAL-NAME> \ --role Contributor \ --scope $VNET_ID \ --query password \ --output tsv) SP_ID=$(az ad sp show \ --id http://<SERVICE-PRINCIPAL-NAME> \ --query appId \ --output tsv)
You will need Owner role on your subscription for this step to succeed.
Create an AKS cluster.
 There is a list of all possible node sizes for you to choose from, but not all might be available in your location. If you get an error whilst creating the cluster you can try changing either the region or the node size.
--node-vm-size
--enable-vmss deploys the cluster as a scale set.
--enable-vmss
--enable-cluster-autoscaler installs a Cluster Autoscaler onto the cluster (though counterintuitively, does not enable it!).
--enable-cluster-autoscaler
--min-count/--max-count are the minimum/maximum number of nodes in the cluster at any time.
--min-count
--max-count
--kubernetes-version installs a specific version of Kubernetes onto the cluster. To autoscale, we require >= v 1.12.4, though it’s recommended to use the most recent version available.
--kubernetes-version
>= v 1.12.4
--service-principal is the application ID of the service principal we created
--service-principal
--client-secret is the password for the service principal we created
--client-secret
--dns-service-ip is an IP address assigned to the Kubernetes DNS service
--dns-service-ip
--docker-bridge-address is a specific IP address and netmask for the Docker bridge, using standard CIDR notation
--docker-bridge-address
--network-plugin is the Kubernetes network plugin to use. In this example, we have used Azure’s own implementation.
--network-plugin
--network-policy is the Kubernetes network policy to use. In this example, we have used Azure’s own implementation.
--network-policy
--service-cidr is a CIDR notation IP range from which to assign service cluster IPs
--service-cidr
vnet-subnet-id is the application ID of the subnet we created
vnet-subnet-id
This should take a few minutes and provide you with a working Kubernetes cluster!
If you’re using the Azure CLI locally, install kubectl, a tool for accessing the Kubernetes API from the commandline:
az aks install-cli
Note: kubectl is already installed in Azure Cloud Shell.
Get credentials from Azure for kubectl to work:
kubectl
az aks get-credentials \ --name <CLUSTER-NAME> \ --resource-group <RESOURCE-GROUP-NAME> \ --output table
--name is the name you gave your cluster
This automatically updates your Kubernetes client configuration file.
Check if your cluster is fully functional
kubectl get node
The response should list three running nodes and their Kubernetes versions! Each node should have the status of Ready, note that this may take a few moments.
Ready
Enabling Autoscaling
We now move to the Azure Portal to enable autoscaling and set rules to manage the Cluster Autoscaler.
First we need to register Microsoft Insights for use on the active subscription.
az provider register --namespace microsoft.insights
To check the status of the registration, run the following command:
az provider show -n microsoft.insights
Once the application has been registered, navigate to your active subscription on the Portal.
Under “Resources”, select the VMSS. It should be named something like aks-nodepool1-<random-str>-vmss.
aks-nodepool1-<random-str>-vmss
From the left-hand menu, select “Scaling”. Click the blue “Enable autoscaling” button and an autogenerated form for a scale condition will appear. We will add two new rules to this condition:
Increase the instance count by 1 when the average CPU usage over 10 minutes is greater than 70%
Decrease the instance count by 1 when the average CPU usage over 10 minutes is less than 5%
Make sure the “Scale based on metric” option is selected and click “+ Add new rule”, another autogenerated form will appear. This will be pre-filled with the required settings to fulfill our first rule, so save it by clicking “Update” and click “+ Add new rule” again.
The second form needs to be edited for the second rule to decrease the instance count by 1 when the average CPU usage over 10 minutes is less than 5%. Save this rule and then save the overall scale condition, the cluster will be updated automatically.
This form can also be used to change --node-count/--min-count/--max-count that was set previously by using the “Instance limits” section of the scale condition (“Default”, “Minimum” and “Maximum” respectively).
If you prefer to use the command line, you can run the following:
az aks update \ --name <CLUSTER-NAME> \ --resource-group <RESOURCE-GROUP> \ --update-cluster-autoscaler \ --min-count <DESIRED-MINIMUM-COUNT> \ --max-count <DESIRED-MAXIMUM-COUNT> \ --output table
Both --min-count and --max-count must be defined.
If you create the cluster using the Azure Portal you must enable RBAC. RBAC is enabled by default when using the command line tools.
Congrats. Now that you have your Kubernetes cluster running, it’s time to begin Setup JupyterHub.

Building web services in Go
Richard Crowley
Richard Crowley
Gambling-as-a-Service
Licensed and regulated so game developers don’t have to be
Data and a set of operations on that data
Networked using the HTTP protocol
Structured and machine-parseable requests and responses
package main import ( "fmt" "net/http" ) func main() { http.HandleFunc( "/", func(w http.ResponseWriter, r *http.Request) { fmt.Fprintln(w, "Hello, www!") }, ) http.ListenAndServe(":8080", nil) }
func(w http.ResponseWriter, r *http.Request)
// In the standard library's net/http/server.go: type Handler interface { ServeHTTP(ResponseWriter, *Request) }
This is the lowest common denominator
Embrace it
type handler struct{} func (h *handler) ServeHTTP( w http.ResponseWriter, r *http.Request, ) { w.Header().Set("Content-Type", "text/plain") w.WriteHeader(http.StatusOK) fmt.Fprintln(w, "Hello, www!") }
This time, set the status code and Content-Type
header explicitly
func (h *handler) ServeHTTP( w http.ResponseWriter, r *http.Request, ) { w.Header().Set("Content-Type", "application/json") w.WriteHeader(http.StatusOK) enc := json.NewEncoder(w) if err := enc.Encode(&MyResponse{}); nil != err { fmt.Fprintf(w, `{"error":"%s"}`, err) } }
Suddenly, things are a lot more verbose
type notFoundHandler struct{} func (h *notFoundHandler) ServeHTTP( w http.ResponseWriter, r *http.Request, ) { w.Header().Set("Content-Type", "text/plain") w.WriteHeader(http.StatusInternalServerError) fmt.Fprintln(w, "500 Internal Server Error") }
Responding with an error is too similar to responding normally
There’s no error
anywhere
func fail() error { return errors.New("fail") } func multifail() (*Win, error) { return nil, errors.New("multifail") }
Conventionally return an error
last
There are no exceptions because errors are not exceptional
Use error
to communicate what happened to the caller
Handlers often call other handlers
Some handlers multiplex requests to several other handlers
Some handlers serve static content
Some handlers transform requests or responses
func main() { mux := http.NewServeMux() mux.Handle("/", &handler{}) server := &http.Server{Handler: mux} listener, err := net.Listen("tcp", ":8080") if nil != err { log.Fatalln(err) } if err := server.Serve(listener); nil != err { log.Fatalln(err) } }
http.ServeMux
is another http.Handler
Raise your hand if you’ve been burned by BaseHTTPServer
or WEBrick
What’s Serve
do, anyway?
(For one thing, power dl.google.com)
func main() { listener, err := net.Listen("tcp", ":1234") if nil != err { log.Fatalln(err) } for { conn, err := listener.Accept() if nil != err { log.Fatalln(err) } go handle(conn) } }
Goroutine-per-connection is how it’s done
func handle(conn net.Conn) { defer conn.Close() p := make([]byte, 4096) for { n, err := conn.Read(p) if nil != err { log.Println(conn.RemoteAddr(), err) break } log.Printf("%v p: %s", conn.RemoteAddr(), p[:n]) if _, err := conn.Write(p[:n]); nil != err { log.Println(conn.RemoteAddr(), err) break } } }
No callbacks, no miniature state machines
They keep us from repeating ourselves
They provide powerful abstractions
They’re often conceptually greedy
Full of magic
Often incompatible with http.Handler
Inspired by Dropwizard
How Betable builds web services in Go
github.com/rcrowley/go-tigertonic
mux := http.NewServeMux() mux.Handle("/", &handler{})
http.ServeMux
only routes prefixes
mux := tigertonic.NewTrieServeMux() mux.Handle("GET", "/foo/{bar}/baz", &handler{})
tigertonic.TrieServeMux
is method- and wildcard-aware
Responds 404 and 405 appropriately
type TrieServeMux struct { methods map[string]http.Handler param *string paths map[string]*TrieServeMux pattern string }
Handle
produces a tree of TrieServeMux
Your handlers are the leaves in methods
Wildcards are added to r.URL.Query
handler := tigertonic.Marshaled(func( url.URL, http.Header, *MyRequest, ) (int, http.Header, *MyResponse, error) { return http.StatusOK, nil, &MyResponse{}, nil })
Static request and response types
No hassling with json.Encoder
Responds 400, 406, and 415 appropriately
Responds with JSON in case of error, too
Still an http.Handler
handler := tigertonic.Marshaled(func( url.URL, http.Header, *MyRequest, ) (int, http.Header, *MyResponse, error) { return http.StatusOK, nil, &MyResponse{}, nil })
Verify the function arity and parameter types at early runtime
Accept arbitrary types for the request and response bodies
decoder := reflect.ValueOf(json.NewDecoder(r.Body)) out := decoder.MethodByName("Decode").Call([]reflect.Value{ reflect.New(m.v.Type().In(2).Elem()), })
Your code only sees static types
json.NewEncoder(w).Encode(response)
Just like earlier but handled by the framework
func writeJSONError(w http.ResponseWriter, err error) { w.Header().Set("Content-Type", "application/json") w.WriteHeader(errorStatusCode(err)) if jsonErr := json.NewEncoder(w).Encode(map[string]string{ "description": err.Error(), "error": errorName(err, "error"), }); nil != err { log.Println(jsonErr) } }
Status code from StatusCode()
or 500
"error"
from Name()
or type
"description"
is the error itself
handler := tigertonic.If( func(r *http.Request) (http.Header, error) { if "" == r.Header.Get("X-Condition") { return nil, Forbidden{errors.New("forbidden")} } return nil, nil }), protectedHandler, )
If
naturally wraps any http.Handler
Special case of First
middleware chains
And yes, it’s an http.Handler
handler := tigertonic.First( enforceRateLimit, checkAuthorization, doActualWork, )
Call ServeHTTP
on a list of handlers
The first handler to call w.WriteHeader(...)
ends the process
This is the real problem for production-ready web services
http.Handler
through and through
handler = tigertonic.Logged(handler, nil)
tigertonic.Logged
for full (optionally redacted) request and response logs
handler = tigertonic.ApacheLogged(handler)
tigertonic.ApacheLogged
for Apache combined logs
handler = tigertonic.Counted(handler, "my-handler", nil) handler = tigertonic.Timed(handler, "my-handler", nil)
tigertonic.Counted
and tigertonic.Timed
for knowing how many and how fast
We mostly use tigertonic.Timed
on each route individually
code, header, response, err := create( mocking.URL(mux, "POST", "http://example.com/1.0/stuff"), mocking.Header(nil), &MyRequest{"ID", "STUFF"}, ) // Now make assertions!
Construct a fake request
Call your Marshaled
function directly
Or call ServeHTTP
with an httptest.ResponseRecorder
URL namespaces
Virtual hostnames
HTTP Basic auth
CORS basics
TLS defaults
github.com/rcrowley/go-tigertonic/pull/54
Adds a sync.WaitGroup
to net.Listener
and net.Conn
Adds Connection: close
to responses written after the listener is closed
Embrace http.Handler
Provide abstractions within
Remember that errors are not exceptional

2 Part II - Object features for classification
2.1 Question 1
What becomes obvious if you compare the values for the two objects of the chessboard segmentation?
Chessboard segmentation is the simplest way to create super-pixels in an image. For answer this question, the image was firstly segmented into blocks (see image below) of size 10x10 and the following features were added: NDVI, blue band, max blue band value in the block, area, and the shape index.
When comparing two different objects, one corresponding to a boat and the other to a river, we note that for this specific example, all features present a similar value except those related to the spectral values (i.e. NDVI and blue band values).
2.2 Question 2
Which features don’t make that much sense in this case?
All those features related to the geometry of the objects (e.g. area, perimeter, etc.) since the chessboard segmentation creates homogeneous objects. For instance, for all the objects in the image the area always will be 100 pixels units due to that the block is of 10x10 pixels.
2.3 Question 3
How many objects were classified as “water”?
For the question 3 and 4 we carry out a multiresolution segmentation. As figure 4 and figure 5 shows, the geometry features (e.g. area) has more relevance in comparison to chessboard segmentation.
Using a simple threshold we classify the objects in the image in:
- vegetation: NDVI >= 0.25
- high_air_quality
- low_air_quality
- water: NDVI <= -0.15
- boat: Using relative border to, if the object is completely surrounded by water.
After the threshold-based classification, we obtain 3 objects of class water.
2.4 Question 4
What is the area of the whole vegetation class (if you select the vegetation class to generate the feature, it will summarize the values from the grouped sub-classes)?
We obtain a vegetation area of 158660 pixel units or 0.0571176 km2.
2.5 Question 5
What is the meaning of the distance value when you create the feature?
For this question a second object level is created with a scale of 50, shape 0.5, and compact 0.5.
In this case, the vegetation super-class contains the classes, high_air_quality and low_air_quality. We can create a new feature based on the relations between super and sub-classes. The distance argument represents the hierarchical distance to the super-object.


Preparation time
over 2 hours
Cooking time
10 to 30 mins
Dietary
A retro classic wonderfully flavoured with honey and rum.
Grease a deep 12-hole muffin tin or 8-10 metal rum baba moulds set on a baking tray.
Place the currants in a pan with the rum and cold water. Place over a medium heat and bring to the boil. Once boiled, remove from the heat and set aside to cool.
Sift the flour into a large bowl and stir in the yeast and salt. Whisk the beaten eggs in a separate bowl with the milk and honey until well combined. Gradually mix the egg mixture and the 115g/4oz butter into the dry ingredients with a wooden spoon. Beat for about 4-5 minutes, or until smooth and glossy.
Drain the currants, reserving the rum, and stir the currants into the batter. Spoon the mixture into the prepared tin and set aside in a warm place to rise for about an hour, or until the mixture has roughly doubled in size. The batter should reach the top of the muffin tins.
Preheat the oven to 190C/375F/Gas 5. Bake the rum babas in the oveb for 12-15 minutes or until risen and golden-brown.
Meanwhile, for the syrup, place the sugar into a saucepan with the cold water and heat gently, stirring occasionally until the sugar dissolves. Bring to a simmer, then add the reserved rum, the additional four tablespoons of rum and the honey. Simmer for a few more seconds, then remove from the heat and set aside.
Remove the rum babas from the oven and allow to cool in the tin for five minutes. Loosen the sides with a blunt-ended knife and turn the rum babas out into a large, shallow ceramic dish.
Pour half of the syrup slowly over the rum babas. Set aside for five minutes to allow the syrup to be absorbed.
Carefully turn the rum babas over in the dish. Pour over the remaining syrup, reserving a few tablespoons for serving, and leave the rum babas to stand for a further ten minutes. Turn them over one final time, then cover the dish with cling film and chill in the fridge for at least two hours before serving. (They will keep for 2-3 days in the fridge.)
To serve, spoon one rum baba per person onto a serving plate and spoon over a little bit of the syrup in the dish and a few spoonfuls of double cream.

Friendly: Hearts of Oak held in Accra by Wa All Stars
Hearts of Oak
Hearts of Oak were left frustrated after being held to a 1-1 draw by Wa All Stars in a friendly match played on Sunday at the Accra Sports Stadium.
The Phobians, who celebrated their 108th anniversary last Monday, could not put smiles of the faces supporters as they failed to beat the former league champions.
Wa All Stars, who had former Ghana goalkeeper Fatau Dauda, drew first blood on the stroke of halftime when Gerald Arkson curled in an effort from the edge of the box.
Hearts of Oak had to wait until the 77th minute to find the equaliser. Obeng Jr found the net with a fine header.
Hearts would have snatched the winner late on had not been for the experience of Fatau Dauda to keep the scoreline level.


The simple answer is ‘yes’, given some additional hardware. The clocks that PsychoPy uses do have sub-millisecond precision but your keyboard has a latency of 4-25ms depending on your platform and keyboard. You could buy a response pad (e.g. a Cedrus Response Pad ) and use PsychoPy’s serial port commands to retrieve information about responses and timing with a precision of around 1ms.
That said, PsychoPy does aim to give you as high a temporal precision as possible, and is likely not to be the limiting factor of your experiment.
Monitors have fixed refresh rates, typically 60 Hz for a flat-panel display, higher for a CRT (85-100 Hz are common, up to 200 Hz is possible). For a refresh rate of 85 Hz there is a gap of 11.7 ms between frames and this limits the timing of stimulus presentation. You cannot have your stimulus appear for 100 ms, for instance; on an 85Hz monitor it can appear for either 94 ms (8 frames) or 105 ms (9 frames). There are further, less obvious, limitations however.
For ‘’CRT (cathode ray tube) screens’‘, the lines of pixels are drawn sequentially from the top to the bottom and once the bottom line has been drawn the screen is finished and the line returns to the top (the Vertical Blank Interval, VBI). Most of your frame interval is spent drawing the lines with 1-2ms being left for the VBI. This means that the pixels at the bottom are drawn ‘’‘up to 10 ms later’‘’ than the pixels at the top of the screen. At what point are you going to say your stimulus ‘appeared’ to the participant? For flat panel displays, or (or LCD projectors) your image will be presented simultaneously all over the screen, but it takes up to 20 ms(!!) for your pixels to go all the way from black to white (manufacturers of these panels quote values of 3 ms for the fastest panels, but they certainly don’t mean 3 ms white-to-black, I assume they mean 3 ms half-life).
Warning
If you’re using a regular computer display, you have a hardware-limited temporal precision of 10 ms irrespective of your response box or software clocks etc... and should bear that in mind when looking for effect sizes of less than that.
Yes. Generally to do that you should time your stimulus (its onset/offset, its rate of change...) using the frame refresh rather than a clock. e.g. you should write your code to say ‘for 20 frames present this stimulus’ rather than ‘for 300ms present this stimulus’. Provided your graphics card is set to synchronise page-flips with the vertical blank, and provided that you aren’t dropping frames the frame rate will always be absolutely constant.


"Hershey's Cookies n Creme Candy bar" consumes roughly 6.2 litres of water to manufacture... it is more sustainable
and better! Keep it up! In fact, the water consumed to produce fell by 19.3%!
"Kinder Bueno Chocolate" consumes roughly 12.4 litres of water to manufacture... it is quite water intensive!
Moreover, the manifacturing on "Kinder Bueno Chocolate" has risen by 19.4% since 2012.
