This project is on implementing improved/combined distributed coordination architecture for MMOGs (Massively Multiplayer Online Games).
Massively Multiplayer Online Games have become very popular nowadays. Main facts about MMOGs are thousands of concurrent players and huge game world. The ‘Distributed’ aspect of these games is an interesting area for game developers. There are specific challenges in developing MMOGs. Effect of latency, performance, security and game cheating are some of the key challenges which should be addressed in MMOGs development.
There are several architectures used in MMOGs. Basic architectures in use are client-server and peer-to-peer. Client-Server architecture is more popular due to the ease of implementing. There are separate architectures to handle the ‘Distributed’ nature of these games too. Matrix, Colyseus, are some implementations done to overcome key challenges in MMOG.
Examples:
Game State distribution is mostly handled using zoning (game world partitioning), instancing and replication (keeping duplicate objects in nodes and updating them). Sometimes, a combination of those methods is also used. It is all about finding an efficient distributed architecture.
We try to provide the developers the chance to experiment on developing games using different algorithms and architectures. Furthermore, we hope to provide performance analysis on different architectures and introduce optimal architectures.
During our project we focus on learning about the architecture already in use in MMOGs, and implement some of them that look promising. That will give us much better understanding about algorithms in use, and then we can try to improve/ combine those algorithms. There are lots of room to improve, specially learning from parallel programming paradigms.
Through this project, we implement few promising architectures and evaluate key strengths and weaknesses of those architectures. The results of the observations will be useful for the future MMOG implementations which are more scalable, strong in performance and fault tolerant. One of the major outcomes of this project is an open source framework for the game developers that give an interface to develop similar MMOGs. By using this framework, developers do not have to bother about developing the lower level of the distributed coordination in MMOGs.
Project Scope is on distributed coordination architecture designed for MMOGs. In this project our initial focus is on the basic and classical architectures used to build MMOGs. We will research about the basic qualities of existing architectures such as performance and scalability. Then we will continue our research to optimize those classical architectures or design new architectures to support MMOGs. We will implement one or few architecture and evaluate the functionality in the perspective of scalability, performance and other qualities. We hope to research about existing algorithms used to handle distributed coordination and use them in more beneficial way to face the challenges in MMOGs development.
MMOG architectures have both client-server and P2P (Peer to Peer) architectures. Even Though Client-Server based implementations can be found easily, P2P based implementations are quite rare and the algorithms used in are complex. There are no good implementations for DHT (Distributed Hash Table) in P2P. It takes approximately four years for a MMOG to be developed.[2]
The basic approach in most MMOGs is to divide the game world into regions. We have to focus on optimizing that approach, as it would be rather time consuming to come up with a completely new approach. Nevertheless, we will not abandon the chance for a completely new idea too.
When using HttpServlets, most people get confused of the usage of the 'init' method. There are two 'init' methods, that are associated with servlets: init() and init(ServletConfig). When we want to do some startup work, in the servlet we override 'init(ServletConfig)' method, in our servlet class, not the no-argument init() method. The no-argument init method is called from inside the init(ServletConfig) method itself.
Let's go through an example, which prints out 'HelloWorld!!', with the tomcat server startup.
package com.example.servlets; import java.io.IOException; import javax.servlet.ServletConfig; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class InitServlet */ public class InitServlet extends HttpServlet { private static final long serialVersionUID = 1L; /** * @see HttpServlet#HttpServlet() */ public InitServlet() { super(); } public void init(ServletConfig config) throws ServletException { super.init(config); System.out.println("Hello World!!"); } /** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse * response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } /** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse * response) */ protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } }
In the above code we can see, the overridden init(ServletConfig) method, first calls to its' super class init method. After that, we can insert any code we need. Here I inserted
System.out.println("Hello World!!");
We can start the 'tomcat' server and see, the result as below
May 7, 2013 10:16:11 PM org.apache.catalina.core.AprLifecycleListener init INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server:/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64:/usr/lib/jvm/java-6-openjdk-amd64/jre/../lib/amd64:/usr/java/packages/lib/amd64:/usr/lib/x86_64-linux-gnu/jni:/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu:/usr/lib/jni:/lib:/usr/lib May 7, 2013 10:16:11 PM org.apache.tomcat.util.digester.SetPropertiesRule begin WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:ServletInit' did not find a matching property.

We can see, 'Hello World!!' is printed with the server startup, not after server start. Thus, we can use this init method, to do tasks like creating pre database connections.
Important Fact: Make sure you add, the servlet you created to the web description file (web.xml) with the load-on-startup tag. The init(ServletConfig) method, starts with the tomcat server, when this tag is mentioned in your web.xml.
For the above servelt it is like,
<servlet> <description></description> <display-name>InitServlet</display-name> <servlet-name>InitServlet</servlet-name> <servlet-class>com.example.servlets.InitServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>InitServlet</servlet-name> <url-pattern>/InitServlet</url-pattern> </servlet-mapping>
This tag, indicates, the order which the servlets will be initialized. I used the value '2' as, I have another servelt to start before this, with the value '1'.

“Dave, we are approaching Janus-42. We will be there within an hour.”
 As an explorer you spend a lot of time in space, and after over nine months you have almost reached your destination. You can rest your feet on solid ground again, if the preliminary readings are correct.

The droid’s real name is T.I.G.-1999, but you named your droid . It feels more personal for your little friend.
With Alfred on your arm you begin the final inspections: space suit, landing pod, food, etc.
“Urgent message from Corporate,” Alfred announced.
“Patch it through Alfred.”
 “Due to a lawsuit and changes taking place with rules and regulations all ships are required to return to Corporate immediately. All current assignments have been canceled until further notice.”
You slump down in a chair. Less than an hour away and you are commanded to return to Corporate. Another nine months in space.


After reading these experience reports on absinthe, I just had to cringe, as there is so much exaggeration in many of them, that not only are a good deal of these reports misleading, but are bordering on pathetic.
For example, in the report entitled, 'A Total Sensory Experience', the author claims that he/she went to a bar in New Orleans and was served 'real absinthe'. I am from New Orleans, I know the bar in question, and this couldn't be further from the truth. The brand of liquor in question, 'Absente', isn't absinthe, and contains no wormwood. This is nothing more than an overpriced pastis, is completely legal everywhere (because it isn't absinthe), and doesn't even taste like absinthe. This person was completely duped, and just goes to show how a combination of exaggeration, wishful thinking, and a bit of ignorance can make for a sensational, albeit misleading 'report'.
Several points to consider:
Absinthe isn't/wasn't made by steeping herbs in vodka, Pernod, or everclear. You'll no more than make absinthe via this method than you'll make wine by adding grape juice to vodka. Even if you attempt distillation, you'll probably end up with a nasty result, which is exactly what was described in the document herein entitled, 'Absinthe Experiment'. This attempt was a total failure. Why? Because there is much more to making absinthe than can be described in a paragraph or two of badly translated information (e.g. 'Arnold recipe'), and you won't be successful using this information, regardless of what equipment you have.
Modern absinthe (or 'absinth') is only a ghost of what the original liqueur was. I know this because I own three preserved bottles of fine label original absinthe (e.g. Pernod Fils, etc.).  FWIW, there is currently no modern product I have had yet which is like the originals.

Code completion improved.
Installation document revised.
Using new installer and uninstaller programs on Windows.
The new installer and uninstaller require that Visual C++ Runtime Libraries are installed to the computer to which the Cmajor application is deployed.
You may already have them installed on to your computer, but if this is not the case they can be downloaded here:
https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0
Download and run the vc_redist.x64.exe package.
The Windows installer of this version is broken. The source code version and the Linux versions should be fine. There's a newer 4.2.0 version available that has working Windows installer.


Stimulus is a new Javascript framework that’s been published this year (2018) by the guys behind Basecamp.
This demo was made to show Stimulus-based controllers, actions and targets. As proof of concept it implements a rough controller which places server-side rendered markup into DOM. As a result this demo feels like a single-page application (SPA) even though it is in fact a multi page application (MPA). Think of Stimulus without the need of Turbolinks.
Sidenote: This demo is consuming data from JSONPlaceholder a fake online REST API.


The daemontools way of logging for many years has been to just write to standard error. After a decade and a half of pressure, quite a few services can be set up to work this way nowadays. Many services can thus have their logging handled independently of that of other services, by a dedicated "log" service running behind a security partition, removing the problems of centralized logging such as vulnerability to flooding attacks, a single I/O bottleneck, and mixture of trusted and untrusted content. But there remain some diehards that cannot be configured this way.
The klog-read
and syslog-read
commands form the bases of services that can handle old log mechanisms.
klog-read
is a simple UCSPI program that expects its standard input to be stream-based.
syslog-read
is a simple UCSPI program that expects its standard input to be datagram-based.
They are intended to be more secure than the old-style rsyslog
or Wettstein syslog
programs.
They are also simpler, by design.
They leave off some of the bells and whistles of those programs, which are less necessary with this toolset or approached an entirely different way.
Logs are already distributed into multiple sets, by the very nature of dedicated "log" services; logs are already autorotated; logs are already strictly size-capped.
All of these are the domain of a "log" service that is security-partitioned from the services running klog-read
or syslog-read
.
They also build upon service management mechanisms.
Not providing (for example) UDP log service is a simple matter of stopping and disabling the udp-syslog-read
service with service management tools, just like any other service.
Plumbed together with fifo-listen
, klog-read
forms the klog
service.
This service listens to the operating system kernel's log device (/dev/kmsg
on Linux, /dev/klog
on the BSDs) and writes out all that it receives.
It feeds an ordinary log service, so kernel logs end up in a normal, automatically rotated, strictly size capped, set of log files like any other.
Plumbed together with local-datagram-socket-listen
, syslog-read
forms the local-syslog-read
service.
This service listens to the GNU C library's log socket (/dev/log
on Linux, /run/log
on the BSDs) and writes out all that it receives.
Plumbed together with local-datagram-socket-listen
, syslog-read
forms the systemd-syslog-read
service.
This service listens to the systemd-journal's log socket (/run/systemd/journal/syslog
) and writes out all that it receives.
Plumbed together with udp-socket-listen
, syslog-read
forms the udp-syslog-read
service.
This service listens to the conventional "syslog" UDP port and writes out all that it receives.
They all feed ordinary log services, so local and remote logs end up in a normal, automatically rotated, strictly size capped, set of log files like any other. The services are entirely independent, though. This has various security benefits.

MIUI 12 will bring a global dark mode - Gizchina.com
by Efe UdinMIUI 12 will bring a global dark mode
4 (80%) 11 votes
Chinese manufacturing giant, Xiaomi, is consistently upgrading its MIUI system to the delight of loyal followers. However, there have been reports that Oppo is poaching a lot of system engineers from MIUI and Meizu’s Flyme OS. Yesterday, some netizens commented on the MIUI official Weibo handle to verify the rumors. They asked, “Are MIUI engineers poached by Oppo gone?”. In response, he revealed a piece of information regarding the next-generation MIUI 12.
In response to this statement, MIUI Screening/Vientiane Screen/Dark Mode Manager @MIUICat responded, “Because engineers are in the company for 13 hours a day, there is no time to go out for an interview. So it is difficult to poach”. In addition, @MIUICat also gave the reason why the custom GIF animation picture loop playback function of the Vientiane screen is not currently active. This is because the function will bring power consumption problems. As of now, it is still in internal evaluation. Most importantly, he added “Looking forward to the global dark mode implementation in MIUI 12”.
The stable version of MIUI 11 started rolling out in mid-October. While Xiaomi is preparing this update for more devices, it is also adding some new features. Earlier, there were reports that Xiaomi is preparing Focus mode, Vientiane screen custom image & Class schedule features for MIUI 11. However, these new features are still in the internal testing stage. In addition, the company also adds the new drawer mode to the system desktop. Furthermore, MIUI 11 now has notifications’ sound effect changes with time. It will be interesting to see how the global dark mode will work on MIUI 12. Nevertheless, we will have to wait for a couple of months.

SDCC allows interrupt service routines to be coded in C, with some extended keywords.
void timer_isr (void) interrupt 2 using 1 { .. }
The number following the 'interrupt' keyword is the interrupt number this routine will service. The compiler will insert a call to this routine in the interrupt vector table for the interrupt number specified. The 'using' keyword is used to tell the compiler to use the specified register bank (8051 specific) when generating code for this function. Note that when some function is called from an interrupt service routine it should be preceded by a #pragma NOOVERLAY (if it is not reentrant) . A special note here, int (16 bit) and long (32 bit) integer division, multiplication & modulus operations are implemented using external support routines developed in ANSI-C, if an interrupt service routine needs to do any of these operations then the support routines (as mentioned in a following section) will have to recompiled using the --stack-auto option and the source file will need to be compiled using the --int-long-rent compiler option.
If you have multiple source files in your project, interrupt service routines can be present in any of them, but a prototype of the isr MUST be present in the file that contains the function 'main'.
Interrupt Numbers and the corresponding address & descriptions for the Standard 8051 are listed below. SDCC will automatically adjust the interrupt vector table to the maximum interrupt number specified.
Interrupt # Description Vector Address 0 External 0 0x0003 1 Timer 0 0x000B 2 External 1 0x0013 3 Timer 1 0x001B 4 Serial 0x0023
If the interrupt service routine is defined without a register bank or with register bank 0 (using 0), the compiler will save the registers used by itself on the stack (upon entry and restore them at exit), however if such an interrupt service routine calls another function then the entire register bank will be saved on the stack. This scheme may be advantageous for small interrupt service routines which have low register usage.
If the interrupt service routine is defined to be using a specific register bank then only "a","b" & "dptr" are save and restored, if such an interrupt service routine calls another function (using another register bank) then the entire register bank of the called function will be saved on the stack. This scheme is recommended for larger interrupt service routines.
Calling other functions from an interrupt service routine is not recommended avoid it if possible.

PyScript introduction¶
The pyscript module provides functionality for transpiling Python code to JavaScript.
Quick intro¶
This is a brief intro for using PyScript. For more details see the sections below.
PyScript is a tool to write JavaScript using (a subset) of the Python
language. All relevant buildins, and the methods of list, dict and str
are supported. Not supported are set, slicing with steps,
**kwargs
, with
, yield
. Imports are not supported. Other than that,
most Python code should work as expected, though if you pry hard enough the
JavaScript may shine through. As a rule of thumb, the code should behave
as expected when correct, but error reporting may not be very Pythonic.
The most important functions you need to know about are
py2js
and
evalpy
.
In principal you do not need knowledge of JavaScript to write PyScript
code.
Goals¶
There is an increase in Python projects that target web technology to handle visualization and user interaction. PyScript grew out of a desire to allow writing JavaScript callbacks in Python, to allow user-defined interaction to be flexible, fast, and stand-alone.
This resulted in the following two main goals:
- To make writing JavaScript easier and less frustrating, by letting people write it with the Python syntax and buildins, and fixing some of JavaScripts quirks.
- To allow JavaScript snippets to be defined naturally inside a Python program.
Code produced by PyScript works standalone. Any (PyScript-compatible) Python snippet can be converted to JS; you don’t need another JS library to run it.
PyScript can also be used to develop standalone JavaScript (AMD) modules.
PyScript is just JavaScript¶
The purpose of projects like Skulpt or PyJS is to enable full Python support in the browser. This approach will always be plagued by a fundamental limitation: libraries that are not pure Python (like numpy) will not work.
PyScript takes a more modest approach; it is a tool that allows one to write JavaScript with a Python syntax. PyScript is just JavaScript.
This means that depending on what you want to achieve, you may still need
to know a thing or two about how JavaScript works. Further, not all Python
code can be converted (e.g. **kwargs
are not supported), and
lists and dicts are really just JavaScript arrays and objects, respectively.
Pythonic¶
PyScript makes writing JS more “Pythonic”. Apart from allowing Python syntax
for loops, classes, etc, all relevant Python buildins are supported,
as well as the methods of list, dict and str. E.g. you can use
print()
, range()
, L.append()
, D.update()
, etc.
The empty list and dict evaluate to false (whereas in JS it’s
true), and isinstance()
just works (whereas JS’ typeof
is
broken).
Deep comparisons are supported (e.g. for ==
and in
), so you can
actually compare two lists or dicts, or even a structure of nested
lists/dicts. Lists can be combined with the plus operator, and lists
and strings can be repeated with the multiply (star) operator. Class
methods are bound functions.
Caveats¶
PyScript fixes some of JS’s quirks, but it’s still just JavaScript. Here’s a list of things to keep an eye out for. This list is likely incomplete. We recommend familiarizing yourself with JavaScript if you plan to make heavy use of PyScript.
- JavasScript has a concept of
null
(i.e.None
), as well asundefined
. Sometimes you may want to useif x is None or x is undefined: ...
. - Accessing an attribute that does not exist will not raise an
AttributeError but yield
undefined
. - Magic functions on classes (e.g. for operator overloading) do not work.
- Calling an object that starts with a capital letter is assumed to be
a class instantiation (using
new
): PyScript classes must start with a capital letter, and any other callables must not.
PyScript is valid Python¶
Other than e.g. RapydScript, PyScript is valid Python. This allows creating modules that are a mix of real Python and PyScript. You can easily write code that runs correctly both as Python and PyScript. Raw JS can be included by defining a function with only a docstring.
PyScript itself (the compiler) is written in Python. Perhaps PyScript can at some point compile itself, so that it becomes possible to define PyScript inside HTML documents.
Performance¶
Because PyScript produces relatively bare JavaScript, it is pretty fast.
Faster than CPython, and significantly faster than Brython and friends.
Check out examples/app/benchmark.py
.
Nevertheless, the overhead to realize the more Pythonic behavior can have a negative impact on performance in tight loops (in comparison to writing the JS by hand). The recommended approach is to write performance critical code in pure JavaScript if necessary. This can be done by defining a function with only a docstring (containing the JS code).
Support¶
This is an overview of the language features that PyScript supports/lacks.
Not currently supported:
- import (maybe we should translate an import to
require()
?) - the
set
class (JS has no set, but we could create one?) - slicing with steps (JS does not support this)
- support for
**kwargs
(maps badly to JS call mechanism) - The
with
statement (no equivalent in JS) - Generators, i.e.
yield
(not widely supported in JS)
Supported basics:
- numbers, strings, lists, dicts (the latter become JS arrays and objects)
- operations: binary, unary, boolean, power, integer division,
in
operator - comparisons (
==
->==
,is
->===
) - tuple packing and unpacking
- basic string formatting
- slicing with start end end (though not with step)
- if-statements and single-line if-expressions
- while-loops and for-loops supporting continue, break, and else-clauses
- for-loops using
range()
- for-loop over arrays
- for-loop over dict/object using
.keys()
,.values()
and.items()
- function calls can have
*args
- function defs can have default arguments and
*args
- lambda expressions
- list comprehensions
- classes, with (single) inheritance, and the use of
super()
- raising and catching exceptions, assertions
- creation of “modules”
- globals / nonlocal
Supported Python conveniences:
- use of
self
is translated tothis
print()
becomesconsole.log()
(also supportssep
andend
)isinstance()
Just Works (for primitive types as well as user-defined classes)- an empty list or dict evaluates to False as in Python.
- all Python buildin functions that make sense in JS are supported: isinstance, issubclass, callable, hasattr, getattr, setattr, delattr, print, len, max, min, chr, ord, dict, list, tuple, range, pow, sum, round, int, float, str, bool, abs, divmod, all, any, enumerate, zip, reversed, sorted, filter, map.
- all methods of list, dict and str are supported (except a few string methods: encode format format_map isdecimal isdigit isprintable maketrans)
- the default return value of a function is
None
/null
instead ofundefined
. - list concatenation using the plus operator, and list/str repeating using the star operator.
- deep comparisons.
- class methods are bound functions (i.e.
this
is fixed to the instance). - functions that are defined in another function (a.k.a closures) that do not have self/this as a first argument, are bound the the same instance as the function in which it is defined.
Other functionality¶
The PyScript package provides a few other “utilities” to deal with JS code, such as renaming function/class definitions, and creating JS modules (AMD, UMD, etc.).

Figure 1 - WBS of the project
Business part: I realized the business plan of the project. Throughout this whole process, I developed and iterated on the business model canvas and conducted a complete market study, competitive study and positioning study. I also created a pricing model, studied the acceptability of our solution and analyzed the potential fundings. In the following figures, you will find explanatory diagrams on the positioning, the pricing model and the business model canvas. You can also find the whole study in the final report at the end of this section.Figure 2 - Positioning
Figure 3 - Pricing model
Figure 4 - Business Model Canvas
Solution: Our solution is composed of 4 different parts:Figure 5 - General architecture of the project
Device: We decided to monitor pollution by collecting data on the following parameters: Temperature, Pressure, Fine particles, Carbon monoxide, Ozone, Nitrogen dioxide and Sulphur dioxide. You will find the acquisition architecture (both high level and low level) in the following figures.Figure 6 - High level design, Low level design
Transport: We needed to find a low energy protocol for our solution. LoRaWAN was a great choice. This MAC protocol allows long range wireless communication for battery powered devices. It covers both the second and third layer of the OSI model, which ease the creation of multi-devices networks. The Thing Network (TTN) is the biggest open shared LoRaWAN network and it was a great solution to implement the air quality monitoring platform. You will find a typical architecture of LoRaWAN network in the following figure.Figure 7 - LoRaWAN architecture
Computation: We used an OM2M server to store and organize the data in our project. This open source software is the Eclipse implementation of the OneM2M standard. This standard has a transversal position that gives it a high degree of interoperability, adaptability and scalability with discovery and integration mechanisms. You will find the network architecture of the project in the following figure.Figure 8 - Server architecture of the project
We chose to implement a noSQL MongoDB database for the user database because of the lightweight, simplicity and scalability. We implemented a REST API to make the transition between the OM2M server and the user applications. You will find a sequence diagram of the interactions between the OM2M server, the Node.js API and the user application in the following figure .Figure 9 - Sequence diagram of the Node.js server
Visualisation: We chose React-Native to develop our mobil application. Unlike other crossplatform frameworks, React-Native provides native-like application performances and has numerous libraries and APIs.In the end, we successfully delivered a functional prototype of the platform and the application. Check out the final report to see our full project.
I am currently a member of the Do It Ocracy incubator at the IoT Valley. I am working on a startup project called "Billi" with my partner Delphine Thoral. Driven by our common values, our project was born in september. With Billi, we want to make a positive impact on everyday business expenses and bring them towards more eco-responsibility in the office.
The incubator supports us on all the stages of our startup creation. We benefit from daily mentorship, numerous training and various experiences as well as a quality network. This daily immersion in a vibrant ecosystem, allows us to develop the many skills essential to the entrepreneur. This support allowed us to quickly develop our project and was crucial on key stages such as the ideation phase, the validation of the market and the target, the launch of the MVP (Minimum Viable Product)...
You will find more information on the following reports. In the first report I describe the project, show its progress and present our ambitions. In the second report I detail the development process of our final solution: a peer-to-peer e-commerce platform.
Collaborative tools
I worked on two main projects. One project was the development of a crossplatform app for a Norwegian IoT product. I realized the entire design (using Adobe XD) and the frontend development part. For the backend side, I worked hand in hand with remote development partners. I developed the application using the Ionic4 framework with Angular and TypeScript.Development tools [Project 1: Crossplatform app]
The other project was a machine-learning research project aiming to understand the client (a large multinational company) and their needs, and thus optimize the offer and pricing in the market. For this python project, I used various libraries like Pandas for the data preprocessing and TensorFlow or SciKit for the machine learning algorithms. I used Plotly and Power BI to display the various datasets and results.Development tools [Project 2: Machine learning]
In the end, for the first project, we delivered a functional crossplatform app to the client. And for the second project, I highlighted interesting insights from the data. Overall, it was a valuable and rewarding international experience. A great adventure !In this part, you will find an analysis of all the knowledge and skills acquired during my different experiences.

This semester was dense and rich in experiences. The ISS formation allowed me to acquire a lot of skills in the field of IoT and various competencies in both hardware and software. I am confident that I now have the right skills, knowledge and mindset to conduct the develoment of an innovative IT product or service.
I am really grateful that I got the opportunity to join the IoT Valley incubator. It was a rewarding experience and I am proud of my project.
This semester was quite challenging. I had to balance between my startup project and the ISS formation. It was hard to find the right balance. For some projects, I haven't been able to get involved as much as I wanted to. As I had to develop my own startup project and follow the ISS formation remotly, I would say that self training and autonomy were the cornerstone of this semester.
Overall, I am more than satisfied with the steps I carried out and the level of expertise I reached throughout this semester.
The development of this portfolio was extremely interesting. I was able to visualize the depth and the diversity of the skills I developed. I really like this evaluation format. It allows you to take a step back and have a good overview of the overall semester. This portfolio is a faithful representation of the competences I have acquired and a great tool on which I can rely to present the extend of my skills.
I find that the technical part of the portfolio often repeats what has already been said in the reports. I don’t know if it is very relevant to develop the technical aspects twice. Therefore, to avoid the portfolio from being too heavy and repetitive, I sometimes chose not to develop all the technical details.

LITTLE VOICE (1998) Rating = *** out of ****** http://www.reviewfilm.com
In a drab English seaside town, Mari Hoff (Brenda Blethyn) whiles away her middle-aged widowhood in her chaotic home (a closed up record shop) in the local pub. However, she is the last to admit that age is overtaking her, as she totters about in high heels, gaudy make-up and low-cut, tight-fitting tops. She blatantly flirts with the two phone engineers who install her phone, making fun of the shy younger Billy (Ewan McGregor) and his hobby (he keeps homing pigeons). She also screams constantly at her painfully shy daughter, LV (Jane Horrocks). LV (which stands for Little Voice because she is so shy) spends every day in her bedroom which is the only neat room in an otherwise slovenly house. There, she listens to records by Edith Piaf, Shirley Bassey, Judy Garland and others, that her dead father had given to her.
One night, when Mari lurches home from the pub with a washed-up showbiz promoter called Ray Say (Michael Caine) for a bit of slap and tickle, LV breaks into song. She can imitate any of the singers whose records she has listened to for years. Ray sees her as a way of establishing his showbiz credentials and a means of escape from the grotty venues and third-rate acts that he normally peddles. He cajoles her into performing in public (by persuading her that her dead father would approve), and begins to plot her (and his future) career. Meanwhile, Billy (who glimpsed her while installing her mother's phone) tries to meet with her again - since both of them are so shy, the relationship develops very slowly indeed.
The screenplay by Jim Cartwright is based on his own play The Rise and Fall of Little Voice, which also starred Jane Horrocks. The leitmotif of a caged bird is firmly established and relentlessly re-affirmed throughout the movie. Both LV and Billy are too shy to fly free of their shackles - Billy's pigeons are an obvious reminder of their straitened circumstances. However, the film itself never flutters free from its stage origins. Cartwright and director (and co-writer) Mark Herman don't make use of the extra possibilities by transferring the story from stage to screen. The result is that some of the performances are a little too theatrical - dialogue delivered to a live audience requires a more subtle touch for cinema. Brenda Blethyn's performance garnered her a Golden Globe nomination and an Academy Award nomination for a performance which teeters between overwrought and over-the-top, and lapses into parody on several occasions. It's a pity because the character is well written. Michael Caine fares better as the down-at-heel impresario, and deserves his Golden Globe award. Ewan McGregor is quietly effective as a minor character, but it is Jane Horrocks that grabs the attention.
Jane Horrocks has had a varied acting career - she captured headlines for a hard-hitting version of Macbeth (which involved her character urinating on stage nightly) but is probably best known as Bubbles, the airhead assistant in Absolutely Fabulous. She performs all the singing in Little Voice, and she is an excellent mimic as well as singer. However, there isn't much singing in the film. There is, however, a lot of screaming and shouting, courtesy of Blethyn, and as the movie progresses, the story becomes ever more predictable. It is also surprisingly grim, though there are nice flashes of comedy. Unfortunately, there are not enough of them, and the story is not sufficiently plausible or strong to work as a straight drama. Herman's previous directorial effort was Brassed Off, which shares many of the bittersweet, small-scale sensibilities of Little Voice (as well as Ewan McGregor). However, despite his best efforts, Little Voice never really escapes from its stage origins, and the film never really hits the high notes that Horrocks' talent could have delivered.

Webchat alpha prototype
What's this?
This is a prototype implementation of a webchat client. It was created for carrying out user research for the GDS alpha project looking at webchat.
The source code for this is on GitHub.
Instructions
This works best with two devices, or you can use two browser windows.
Open the agent interface and follow the instructions by picking your adviser and writing an optional welcome message. Then click the "Start the chat" button.
In the service prototype, find and click the webchat call to action. Type in your name, and you'll be taken to the queue.
The agent interface will now give you an option to advance the queue, manually. Click 10 times to reach the conversation.
When you're ready to end the conversation, the agent can do it in one click, or the user can also do it by using the top right "end chat" button.
Try chatting
1. Open the agent interface
2. Open a service
We were testing use of webchat with users in Goverment services.
These are not real screens from real services: they helped get the user thinking about a task, instead of webchat or support.
Pay Dartford crossing charge prototype
The task was to pay for using the crossing today.
The prototype does not validate any of the information.
This will always fail to submit the payment.
The webchat call to action is in the footer of all pages.
State pension prototype
The task was to get a state pension forecast.
As a part of this, we made users find their National Insurance number.
Validates typing anything at all into the National Insurance number field. Stops at the postcode page.
The webchat call to action is in the "I cannot find my National Insurance number" section.
Warning!
This is a prototype built for the sole purpose of user testing in a lab. It is not exhaustively tested on all browsers. The browsers we used were Chrome for macOS and Windows, Safari on iOS 9, and Chrome for Android.
The prototype does not work with more than one user and one agent at a time. If someone else is using this prototype, you will see their chats or it may not work properly. You can have more than one chat in a row, but every chat needs to end before a new one can begin. If you manage to break it and desync the agent/user, refresh both starting with the agent and start over.
If you're chatting as a user and you accidentally refresh the interface, you'll resume where you left off. If you refresh as an agent, you'll become desynced and you'll have to start over.
Get in contact
For further information on the webchat alpha, please email Chris Heathcote -<EMAIL_ADDRESS>There is a #webchat channel on UK Government Slack


How Ruto Steals the Show With Unique Dress Codes
by John MbatiWhenever Deputy President William Ruto graces an occasion, foes and friends alike usually wait with curiosity to listen to what he says, whether he will laud or criticise. However, few people notice how he changes attire to suit the occasion.
Ruto's dress code indicates a seasoned politician who knows how to penetrate the hearts of his followers. He has managed to spice up his oration with a little tweak of his wardrobe.
His dressing has become an extension of his gift of the gab.
In July 2014, William Ruto wore a white Islamic robe, with a Keffiyeh (locally known as Arafat scarf) and an Islamic cap as he and President Uhuru Kenyatta met Muslims at Kakamega State Lodge.
In 2018, he showed up in the same regalia, wearing a Muslim garb as he shared an Iftar dinner with Muslims at Charter Hall.
Ruto further traversed into the Asian community and wore a pink turban with a yellow scarf over his dark crisp suit, during a Sikh wedding of Gavneet Chathe and Rajbir Rai in December 2016.
He also graced a Hindu event where he was garlanded with flowers. He participated in the tradition of burning incense.
Ruto further stole the show with a traditional cap, a trademark of the African Divine Church faithful when members of the church visited him in Karen, Nairobi on May 7, 2019.
The cap entails colours, red, white and green. Ruto danced with the faithful in the event as he defended his church donations.
However, what stands out of late, is how he has managed to blend business casual into his dress code in 2019. Ruto has been spotted with khakis, seasonal sport coat, tailored blazers and knit shirts in past events as he sweeps the fashion world with a storm.

@Scott Morrison For the perfectoid project I had to get back to my old https://github.com/PatrickMassot/lean-differential-topology/blob/master/src/homeos.lean defining homeomorphisms. But now we have the category Top in mathlib, and isomorphisms. Can I throw away my file and use the category theory stuff? How would that work?
That's what I did in lean-homotopy-theory. My internet is acting up and I can't provide a direct link, but the filename is src/homotopy_theory/topological_spaces/homeomorphism.lean
great
It looks nice, but I'd like to be able to plug this into the story we have in the separation thread
Do you think it's possible, or does it mean everything must be rewritten in terms of Top instead of topological_space?

Ospreys consider emergency signings after further additions to crippling injury list
They are being hammered in one area in particular
by Mark OrdersThe Ospreys could need to bolster their front-row resources amid a blitz of injuries.
They will likely have to bring in at least one loan signing, possibly two, to ease a situation that has seen them deprived of the services of five players.
Gareth Thomas (knee) and Gheorghe Gajion (ankle) both suffered bumps in the 40-19 Heineken Champions Cup defeat by Racing 92.
They joined Rhodri Jones (shoulder), Tom Botha (lower leg) and Rhys Henry (shoulder) in the casualty room at Llandarcy.
It isn’t yet clear how long Thomas and Gajion will be sidelined for, but the Ospreys need to act quickly, with Ma’afu Fia, Nicky Smith and Wales Under-20s loosehead Jordan Walters the only fit props in their squad.
Their first port of call will be to look to borrow off the other regions.
But time is of the essence with Racing 92 to be played in Paris on Friday evening.
The Liberty Stadium team are also still waiting for an update on Wales centre Owen Watkin, who hurt a knee in the home encounter with Racing. He was booked for scans on Monday afternoon but the region’s medics will need to assess them before any bulletins are released.
Wayne Pivac will keen to learn of those results, too, with Wales’ coach set to name his Six Nations squad in barely five weeks and Jonathan Davies already ruled out by injury.
The injuries to Thomas, Gajion and Watkin mean the Ospreys have 15 players sidelined by injuries, while Dan Evans was red-carded last weekend and Justin Tipuric, Alun Wyn Jones and George North have yet to return after the World Cup.

If I had a chance to remake the high school STEM curriculum to reflect the skills that are actually needed in today’s world, my changes might look something like this:


This Generative Web Application is javascript-based and features kaleidoscopic visuals that can be manipulated by user input. Please use the controls in the upper-right corner to alter the variables.
The primary visual of this application consists of a gird, which may be thought of as houses in a 'neighborhood.' A color-changing background lives behind these houses, and music plays over the neighborhood. The background color may be changed by clicking the mouse anywhere in the browser. The number of squares that form each house can be changed via slider, as can the distance between each house. The neighborhood may be distant and controlled, or it may be crowded and hectic— it's up to the user! The volume of the music may also be controlled via slider.

Recipe 18.6. Implementing a FIFO Container
Credit: Sébastien Keim, Alex Martelli, Raymond
Hettinger, Jeremy Fincher, Danny Yoo, Josiah Carlson
Problem
You need a container that allows element insertion and removal, in
which the first element inserted is also the first to be removed
(i.e., a first-in first-out, FIFO, queue).
Solution
We can subclass list to implement a Pythonic
version of an idea found in Knuth's Art
of Computer Programming: the frontlist/backlist approach
to building a FIFO out of two one-way linked lists.
Here's how:
class Fifo(list):
def _ _init_ _(self):
self.back = [ ]
self.append = self.back.append
def pop(self):
if not self:
self.back.reverse( )
self[:] = self.back
del self.back[:]
return super(Fifo, self).pop( )
Discussion
Here is a usage example, protected by the usual guard so it runs only
when the module executes as a main script rather than being imported:
if _ _name_ _ == '_ _main_ _':
a = Fifo( )
a.append(10)
a.append(20)
print a.pop( ),
a.append(5)
print a.pop( ),
print a.pop( ),
print
# emits: 10 20 5
The key idea in class Fifo is to have an auxiliary
backlist, self.back, to which incoming items get
appended. Outgoing items get popped from the frontlist,
self. Each time the frontlist is exhausted, it gets
replenished with the reversed contents of the backlist, and the
backlist is emptied. The reversing and copying are
O(n),
where n is the number of items appended
since the "front list" was last
empty, but these operations are performed only once every
n times, so the
amortized cost of each call to
pop is a constantthat is,
O(1).
A simpler way to build a FIFO in Python is no doubt to just use a
standard list's append and
pop(0) methodssomething like:
class FifoList(list):
def pop(self):
return super(FifoList, self).pop(0)
However, when using a list in this way, we need to keep in mind that
pop(0)
is
O(n),
where n is the current length of the list.
O(1)
performance can be ensured by building the FIFO in a slightly less
intuitive way, on top of a dictionary:
class FifoDict(dict):
def _ _init_ _(self):
self.nextin = 0
self.nextout = 0
def append(self, data):
self.nextin += 1
self[self.nextin] = data
def pop(self):
self.nextout += 1
return dict.pop(self, self.nextout)
In Python 2.4, we also have
collections.deque, a double-ended queue type that
also ensures
O(1)
performance when used as a FIFO (using its append
and popleft methods):
import collections
class FifoDeque(collections.deque):
pop = collections.deque.popleft
To choose among different implementations of the same interface, such
as the various Fifo... classes shown in this recipe,
the best approach often is to measure their performance on artificial
benchmark examples that provide a reasonable simulation of the
expected load in your application. I ran some such measurements on a
somewhat slow laptop, with Python 2.4, using the
timeit module from the Python Standard Library.
For a total of 6,000 appends and pops, with a maximum length of
3,000, class Fifo takes about 62 milliseconds, class
FifoList about 78, FifoDict about
137, and FifoDeque about 30. Making the problem
exactly ten times bigger, we see the advantages of
O(1)
behavior (exhibited by all of these classes except
FifoList). Fifo takes 0.62 seconds,
FifoList 3.8, FifoDict 1.4, and
FifoDeque 0.29. Clearly, in Python 2.4,
FifoDeque is fastest as well as simplest; if your
code has to support Python 2.3, the Fifo class shown
in this recipe's Solution is best.

What is in Munch for me?
Munch is currently an early stage startup with the mission of making a significant change on the current state of the growing Online Deals Industry. We are developing a platform that makes the Online Food Deals Advertisement that enhances the experience for customers and restaurant owners by giving full control over their experience. By joining us as an investor at this stage you will be at a position to share our journey and enjoy maximum benefits from your investment.
What is in Munch for restaurant owners?
Other platform main channel of revenue is taking a comission fee between 30% and 50%, restaurant owners go with this route because it is the only option but the main competitors in the Industry have been reported to have client disatisfaction of above 50%. Munch is focusing in creating the best experience to restaurant owners by helping them track and modify their offers on real time. Additionally, we will charge restaurant an upfront fee for posting their deals so that they can keep all of the income produced by their sales.
What is in Munch for the users?
Users will recieve deals location based or by filtering restaurants that they like the most. This way, we prevent a flood of unnecesary advertisement while providing the best experience when looking for a deal.
Industry outlook
The current market for Online Deals Advertisement is 3.3 Billion dollars and 23% goes to restaurant deals. In addition, it is projected that by 2016 this market will grow to 5.5 Billion dollars. Munch has a new approach to food deal advertisements that puts us on a strategic position in a growing market.
