22 January 1996
Disease Outbreak Reported
The number of cases of dengue and dengue haemorrhagic fever continued to rise in November, and the epidemic spread to new areas in the Americas. As of 15 November 1995, over 200,000 cases of dengue and more than 5,500 of dengue haemorrhagic fever had been reported to the WHO Regional Office for the Americas/PAHO. Further details in Weekly Epidemiological Record No. 47 (published 24 November 1995).


 While attempting to gain recompense for the ruined rug from his wealthy counterpart, he accepts a one-time job with high pay-off. He enlists the help of his bowling buddy, Walter, a gun-toting Jewish-convert with anger issues. Deception leads to more trouble, and it soon seems that everyone from porn empire tycoons to nihilists want something from The Dude.
My Obervations
- All protagonists are bowlers.
- All antigonists are artists.
- Like in Roadhouse, Sam Elliott is incredible!

music
explorer
available through
|
Music Explorer brings the London Symphony Orchestra, conducted by Sir Colin Davis, to you in your home or in your classroom. Music Explorer consists of a videotape and a 64 page listening guidebook written by Richard McNicol.
On this site, you'll find:
|
|
Introduction to the Materials
|
The guidebook sets out for each piece:
- an introductory page that sets the scene, describing the circumstances in which the piece was written (where possible, in the composer's own words).
- 1st listenings: Getting your bearings. Pages that help the listener get an overall impression of the music by discovering landmarks that give an idea of the span of the piece.
- 2nd listenings: Structure. Explores the way the music is put together (the form).
- 3rd listenings: The icing on the cake. Guides to some of the things that make the music most admirable to the author--designed to provoke involvement and individual response. This section also contains "secrets of the performance" (about gestur
es, expressions, and interactions among the people making the music on the tape) and "can you discover..." (questions to encourage students to explore a little further for themselves).
- Gathering the threads. Answers some of the questions brought up in the introduction: "How was the first performance received?" "What then happens to the composer?" "How does this composer fit into musical history?"

Using Music Explorer in a Standards-based curriculum
Ideas adapted from Richard McNicol's Music Explorer Project Book
|
The Music Explorer package includes a variety of printed exercises useful for individual or for class study. In addition, author Richard McNicol has designed a variety of creative classroom projects. Here are six such projects, chosen for their eff
ectiveness in helping students reach the National Standards in Music Education of the United States of America (note that the Music Explorer materials all are directed toward Standard 9: Understanding music in relation to history and culture).
Note that the sound files that appear in some of these lessons are in MIDI format. You will be able to play them only if your computer is set up to accomodate such files, and the sound quality will depend on the quality of your computer sound card and
other hardware.

import "github.com/ghetzel/go-stockutil/log"
Package log package provides convenient and flexible utilities for logging messages.
Overview
Logging is done by calling functions in this package that correspond to the severity of the log message being output. At the package level, a minimum severity can be set. Messages less severe than this minimum logging level will not be output.
Color Expressions
In addition to the standard printf-style formatting options (as defined in the standard fmt package), this package supports inline expressions that control the output of ANSI terminal escape sequences. These expressions allow for a simple mechanism to colorize log output, as well as applying graphical effects like bold, underline, and blinking text (for terminals that support it).
By default, color expressions will only be honored if os.Stdin is attached to a pseudoterminal. This is the case when the program is run on the command line and is not piped or redirected to another file. This default ensures that the colors are visible only in a visual context, but do not corrupt files or pipelines with ANSI escape sequences. Color sequences can be explicitly enabled or disabled by setting the EnableColorExpressions package variable.
Using color expressions in format strings is done by wrapping the expression in ${expr}. The general format for color expressions is:
foregroundColor[+attributes[:backgroundColor[+attributes]]]
Colors (foreground and background): black red green yellow blue magenta cyan white [0-255]: numeric 8-bit color (for 256 color terminals) reset: Reset all color and graphics attributes to their defaults
Foreground Attributes: b: bold text B: blinking text h: high-intensity (bright text) i: inverted/reverse colors s: strikethrough u: underline
Background Attributes: h: high-intensity (bright text)
Examples
Below are some examples showing various formatting options for logs.
log.Info("Hello, world!")
// [11:22:33 0001] INFO Hello, world!
log.Warningf("The %q operation could not be completed.", "add")
// [11:22:33 0002] WARN The "add" operation could not be completed.
log.Errorf("There was an ${red}error${reset} opening file ${blue+b:white}%s${reset}", filename)
// [11:22:33 0003] ERRO There was an error opening file /tmp/file.txt
// ^^^^^ ^^^^^^^^^^^^^
// red text blue text on white background
Log Interception
It is sometimes useful to be able to act on logs as they are emitted, especially in cases where this package is used in other projects that are imported. Log Interceptors are called before each log line is emitted. The LogInterceptFunc is called with the level the message was emitted with, the message itself as a string, and a stack trace struct that defines exactly where the log was emitted from.
// print a complete stack trace before every debug-level message that is encountered
log.AddLogIntercept(func(level log.Level, line string, stack log.StackItems){
if level == log.DEBUG {
for _, item := range stack {
fmt.Println(item.String())
}
}
})
Writable Logger
The WritableLogger implements the io.Writer interface, acting as a bridge between byte streams from various sources and the log package. This is frequently useful in situations like parsing the output of other programs. A WritableLogger accepts a custom LogParseFunc that allows individual lines being written to the WritableLogger to be parsed, rewritten, and given a log severity level.
import (
"os/exec"
"github.com/ghetzel/go-stockutil/log"
)
wr := log.NewWritableLogger(log.INFO, `ls: `)
wr.SetParserFunc(func(line string) (log.Level, string) {
if strings.Contains(line, `root`) {
// root-owned files show up as errors
return log.ERROR, line
} else if strings.Contains(line, os.Getenv(`USER`)) {
// current user files are notices
return log.NOTICE, line
} else {
// all other lines are not logged at all
return log.DEBUG, ``
}
})
ls := exec.Command(`ls`, `-l`)
ls.Stdout = wr
ls.Run()

LCD Repair
The HP Chromebooks are great until one comes in with a broken LCD. Then, you get to spend 30 minutes questioning every single design decision that HP made when they designed their Chromebooks.
Before repairing any device, verify that the student whose Chromebook you are about to repair does not have insurance.
Materials:
- Screwdriver
- Pry tool
- New HP LCD
- Parts tray
Time: 20-30 minutes
- Turn the device off if you have not already done so.
- Turn the device over and locate the 11 small rubber covers that sit flush with the bottom of the device. There are 10 on the perimeter and one in the center-top of the device near the label.
- Using something sharp and pointy, stab the rubber covers and pull them off. They are glued on but should come off easily. Save them.
- Remove the 11 Phillips-head screws from the bottom of the computer.
- Flip the device over.
- Flip the device back over. You forgot to remove a screw. There are 11 screws. Count them. You forgot the one in the center-top. It's slightly off center.
- Flip the device back over and open it.
- Take the flat end of your pry tool or a small flathead screwdriver and insert it at the seam between the keyboard deck and the body of the computer, then pry up.
- The keyboard is held on by friction and plastic clips. Repeat this process going around the device.
- Lift the keyboard up slightly so it comes out of the body and then open it as if it was the lid of the laptop. You will need to disconnect the keyboard and touchpad ribbon cables.
- Lift the latches that hold the keyboard and touchpad ribbon cables in place and remove them. Place the keyboard off to the side.
- Locate and disconnect the display cable. Do not disconnect the WiFi antennas (as they are a royal pain to reconnect).
- Locate and unscrew the hinges from the base of the device. Be sure not to let it fall back, as this could accidentally disconnect the WiFi antennas.
- The WiFi antenna cables have enough slack in them that you can remove the display assembly from the body and lay it flat on the work surface without disconnecting them.
- On the display assembly, locate the two black stickers at the bottom of the display assembly.
- They are to either side of the bulge of the hinge and at the extreme left and extreme right of the bottom of the display assembly.
- Slide something small and pointy between the sticker and frame of the assembly, and peel it off. Save these.
- Under each sticker is a single screw. Remove it.
- Now, take the flat end of your pry tool or a flathead screwdriver, insert it between the bezel and the base of the display, and pry up. Repeat this process to remove the bezel. Feel free to use your hands once there is enough space for them, it will make the process quicker.
- Locate the four Phillips-head screws holding down the display and remove them.
- The display will fold over onto the keyboard to reveal the back of the display and the display connector.
- Remove the piece of tape holding the display connector in place and disconnect the display.
- Place your new display in the same position the old display was in when you disconnected the cable. Plug in the new display and fold it up into the display assembly, making sure that the display cable is tucked into its channel.
- Reattach the four screws that hold the LCD in place and remove the protective covering from the LCD.
- Attach the bezel, making sure to snap all of the clips back into place. It may take some force, but don't worry about hurting anything.
- Replace the two screws that go in the bottom of the bezel and the stickers that go over them.
- Taking the display assembly, line the hinges up to their mounts on the base and replace the screws that hold them in.
- Reconnect the display and power on the device. This can be accomplished by plugging in the device or by temporarily reconnecting the keyboard to the motherboard. If everything works correctly, make sure both the WiFi antenna and display cables are properly routed in their channels.
- Reconnect the keyboard and touchpad ribbons, and reattach the keyboard to the base. As it is held on by clips and friction, simply apply pressure to the edges until everything snaps into place. There is a clip near the center of the keyboard so be sure to engage that one as well.
- Flip the device over and re-apply the 11 screws that hold the keyboard to the base. Re-apply the rubber feet that cover them.
- Update the ticket and send a bill, if applicable.

Money Play. How should Red play 63?
pips Red=105 White=161
(CorrectAnswer= 0/0, ErrorScore= 0)
The problem with 8/5 for the 3 is that the 6 must be played 13/7, leaving four blots one of which is behind a broken prime. That is just too much risk, coupled with fact that Red’s rear checker will still be behind that broken prime.
The correct play is 23/14 which escapes that checker and there is some mild duplication of White’s 2s. Even after this best play Red is only a 51-49 favourite because of the disjointed nature of his position.
13/7, 8/5 is worse than a quadruple blunder!

We want to have a computer environment that supports and facilitates study and research of Jewish Orthodox texts. (Most of the technological pieces that we need to develop are not at all specific to Jewish Orthodox Texts. On the other hand, desire to facilitate study of such texts is our primary motivation.)
This "dream system" will record various information about the texts and support doing interesting things with them.
On the text level, we want to allow marking up names of people and places, index entries, logical structure of statements, user-defined tags and the like. On the structural level: allow capturing of multiple structures of the same text, for example - chapter/verse and pages of a printed edition. On the intra-text level: record links from one text to another with their types and other metadata, and support link reversal.
The system should support marking up and working with texts that are stored in different systems (WikiMedia, Sefaria etc.).
It should be possible to print any text with glosses formatted nicely.
The system should be accessible through a clean, even minimalist, but powerful web-based interface. Mass participation - proofreading of the texts, marking them up, clarifying the cross-references and such - should be very much supported.
The system should be also accessible through a web-based API, which the UI should be built on top off (think headless CMS). This API should support modification of the document text as text, but also markup-aware operations. Everything doable via UI should be doable via API.
Texts should be retrievable and modifiable in various formats (primarily - TEI), thus supporting text editor workflow.
API and UI built on top of it should support editing and publishing text like this paper :)
Initial conversations in this area took place in 1992-1994, between Leonid Dubinsky and Baruch Gorkin. Most of the requirements were understood then, but not the need for universal web-availability and crowd-sourcing: access to the Internet was not what it is now.
We realized that a standard approach to text markup has to be used, and settled on SGML (XML did not yet exist).
In the summer of 2006, discussions restarted between Dubinsky and Gorkin. Crowd-sourcing and potential commercialization were discussed. In the Fall of 2006, Michoel Koritz joined in.
In 2019, work on the 19 Kislev archive (www.alter-rebbe.org) lead to a renewed interest in the project.


Papaya (Carica papaya) is a perennial fruit tree widely cultivated in tropical and subtropical climates for its nutritive and medicinal values. It is very popular in Kenya where it is grown for both local and export markets. Pawpaw is widely cultivated fruit tree in the tropics and subtropics. It is grown in Kenya as a domestic fruit and small-scale cash crop. The fruits are low in calories and rich in vitamins A, B1, B2 & C, iron and potassium. Papayas enzymes promote digestion easing constipation. Sale of fresh papaya provides regular income for farmers since the fruits are produced through out the year.
Pawpaw fruits are sold and eaten locally as fresh fruit, with high demand from the hotels, local grocery, fruit salad vendors, supermarkets and export market. The fruits are dried and exported as part of a dried fruit mixture. It can be used to make ice-cream flavour, refreshing drinks, jam, jelly, wine, marmalade, candies and crystallized fruits. The latex produced by the unripe fruit is harvested and used in the production of papain, used in the brewing industry, canned meats and pharmaceutical industries. Green fruits are pickled or cooked as a vegetable. Young leaves are sometimes eaten as vegetables.


Gildarts is a tall, muscular man with shoulder-length orange hair (usually kept slicked back) and a stubbly beard. His heavily muscular body is without a left arm and left leg, which he initially replaces with rudimentary wooden prosthetics, completed with an armored knee-guard to function as the knee joint. Later, however, Gildarts switches to more functional, armor-like prosthetic limbs. His chest sports scars, two of which are stitched, and his black Fairy Tail stamp; the majority of his torso is bandaged, as is his right forearm and left shoulder. Gildarts' attire is rather simple; he wears a long, black, high-collared and tattered cloak with shoulder plates; around his waist is a simple belt. Gildarts also wear loose-fitting dark pants, complete with an armored waist-guard bearing plates similar to the ones on his shoulders, tucked inside simple boots.
Gildarts is a laid-back, kind and easygoing person who has great interest and the utmost faith in the new generation of Fairy Tail's Mages. He is rather oblivious, and doesn't pay much attention to his surroundings, as he recognized neither the guild nor Mirajane.He also has a tendency to break through walls with his Crash in order to pass, rather than simply using a door, something which prompted the inhabitants of Magnolia to create the town's rearranging process. Gildarts is, as pointed out by himself, rather bad at holding back during a fight, though he fights in a particular way, so as to prevent human casualties. He also respects his opponents and, very similar to Natsu, takes his opponents neither too lightly nor holds them in too high a regard. Gildarts also won't refuse an offered challenge, though if something more important arises, he may postpone said event. Gildarts appears to be somewhat of a lone wolf, as in X781, he left the guild to partake upon a 100-year quest. Upon being declared the guild's Fifth Master, Gildarts quickly re-passed the mantle back upon Makarov and left the guild once more, suggesting a feeling of discomfort regarding leadership positions, or at least a dislike of added responsibility. In addition, he is a womanizer, having been with at least 13 women since leaving his now-deceased ex-wife 18 years ago.
Crash(Kurasshu):Gildarts' signature Magic, Crash is an extremely powerful Caster Magic that smashes everything the user comes into contact with into pieces. It can be used to both crack Magic into pieces, thereby nullifying its effects, as well as to reduce the Magic's power and to deflect it. Even the most powerful spells are rendered useless when faced with this destructive and advanced Magic, which is difficult to control even for an extremely powerful individual like Gildarts himself. The effects of Crash occasionally manifest themselves as the target being separated into cubes; interestingly, should Crash be directly cast on another living organism, the recipient is separated into numerous, doll-like versions of themselves. After some time, the target should revert to their original form, but should Gildarts wish, he can manually change them back.


At the core of Lachesis is an algorithm insuring that all participants process the
same transactions in the same order. We have chosen to implement a system
suitable for the most adversarial conditions - with powerful attackers. This is
known as Byzantine Fault Tolerance (BFT) and has been a field of research for
over 30 years. Our system is based on our interpretation of a paper published by
Leemon Baird in 2016 <http://www.swirlds.com/downloads/SWIRLDS-TR-2016-01.pdf>
__
which describes a method for extracting a consensus order of events from a
data structure representing the history of gossip between a set of participants.
Instead of only gossiping transactions and exchanging votes directly, members
gossip about gossip itself; something that can be represented in a Directed
Acyclic Graph (DAG) - the poset. The algorithm for extracting a consensus
order from the poset is proven to work and attains the theoretical limits of
Byzantine fault-tolerance in terms of the number and power of the malicious
members it can cope with. The messaging routines required to gossip and create
the poset are very simple compared to other BFT algorithms. The poset
itself, however, is not ideal for representing the ordered list of transactions
because it is a two-dimensional object which doesn't explicitly express a linear
order of the items it contains. Hence, we developed a method to map the
poset onto a blockchain.
A blockchain is a data structure where transactions are packaged in hash-linked blocks. Each block is identified by a cryptographic hash and contains a hash of the previous block, so that blocks can form a chain from the first block ever to the last formed block. In this way, all the block - and transactions - are connected via a linear linked list structure. In our system, blocks contain a collection of signatures of their own hash from the participants. A block with valid signatures from at least one third of validators can be considered valid because - by hypothesis - at least one of those signatures is from an honest member.
Projecting the poset onto a blockchain makes it much easier for third
parties to verify the consensus order. It makes it possible to build
light-clients and to integrate Poset based systems with other blockchains.
For more detail about the projection method, please refer to :ref:blockchain
Lachesis communicates with the App through an AppProxy
interface, which has two
implementations:
SocketProxy
: A SocketProxy connects to an App via TCP sockets. It enables
the application to run in a separate process or machine, and to
be written in any programming language.
InmemProxy
: An InmemProxy uses native callback handlers to integrate
Lachesis as a regular Go dependency.
The AppProxy
interface exposes three methods for Lachesis to call the App:
CommitBlock(Block) ([]byte, error)
: Commits a block to the application and
returns the resulting state hash.
GetSnapshot(int) ([]byte, error)
: Gets the application snapshot
corresponding to a particular block index.
Restore([]byte) error
: Restores the App state from a snapshot.
Reciprocally, AppProxy
relays transactions from the App to Lachesis via a
native Go channel - SubmitCh
- which ties into the application differently
depending on the type of proxy (Socket or Inmem).
Lachesis asynchronously processes transactions and eventually feeds them back to the App, in consensus order and bundled into blocks, with a CommitBlock call. Transactions are just raw bytes and Lachesis does not need to know what they represent. Therefore, encoding and decoding transactions is done by the App.
See the :ref:api
section for more details about the Proxy API.
Lachesis nodes communicate with other Lachesis nodes in a fully connected Peer To Peer network. Nodes gossip by repeatedly choosing another node at random and telling eachother what they know about the poset. The gossip protocol is extremely simple and serves the dual purpose of gossiping about transactions and about the gossip itself (the poset). The poset contains enough information to compute a consensus ordering of transactions.
The communication mechanism is a custom RPC protocol over TCP connections. It
implements a Pull-Push gossip system. At the moment, there are two types of RPC
commands: Sync and EagerSync. When node A wants to sync with node
B, it sends a SyncRequest to B containing a description of what it
knows about the poset. B computes what it knows that A doesn't know
and returns a SyncResponse with the corresponding events in topological
order. Upon receiving the SyncResponse, A updates its poset
accordingly and calculates the consensus order. Then, A sends an
EagerSyncRequest to B with the Events that it knows and B doesn't.
Upon receiving the EagerSyncRequest, B updates its poset and runs
the consensus methods.
The list of peers must be predefined and known to all peers. At the moment, it is not possible to dynamically modify the list of peers while the network is running but this is not a limitation of the Poset algorithm, just an implementation prioritization.
The core of Lachesis is the component that maintains and computes the poset.
The consensus algorithm, invented by Leemon Baird, is best described in the
white-paper <http://www.swirlds.com/downloads/SWIRLDS-TR-2016-01.pdf>
__
and its accompanying document
<http://www.swirlds.com/downloads/SWIRLDS-TR-2016-02.pdf>
.
The poset itself is a data structure that contains all the information about
the history of the gossip and thereby grows and grows in size as gossip spreads.
There are various strategies to keep the size of the poset limited. In our
implementation, the Poset object has a dependency on a Store object
which contains the actual data and is abstracted behind an interface.
There are currently two implementations of the Store interface. The
InmemStore
uses a set of in-memory LRU caches which can be extended to
persist stale items to disk and the size of the LRU caches is configurable. The
BadgerStore
is a wrapper around this cache that also persists objects to a
key-value store on disk. The database produced by the BadgerStore
can be
reused to bootstrap a node back to a specific state.
The Service exposes an HTTP API to query information about the state of the node as well as the underlying poset and blockchain. At the moment, it services two queries:
[GET] /stats:
Returns a map with information about the Lachesis node.

Evolutionary Robotics is a field of study that is concerned with Robotics and Evolutionary Algorithms.
 Traditionally, robot agents have been designed by hand : a careful design of the body of a robot and a set of guidance heuristics to guide the robot to complete a task.
Evolutionary Computing and Machine Learning is an Artificial Intelligence technique in which computers and machinery learn to complete a task through experience. Experience is generated with large amount of data and the machines learn with this data. A simple example is a Reinforcement Learning approach - when a robot agent makes a mistake - it is punished and when it does an act which gives some achievement - the robot agent is rewarded.
There are three approaches in Evolutionary Robotics, the three approaches differ by which element of a robot agent is placed under Evolutionary Control
The three approaches will be conducted by Jae Jang, Ntokozo Philip Zwane and Naeem Ganey
A Simulated Platform of a robot arena was configured to conduct experiments on the various configurations. 20 Robots are spawned randomly and they need to work together to collect boxes and return the boxes to the home area.
Robot Agents are rewarded for collecting boxes and returning them to the home area. There are 3 sizes of boxes in the arena : small, medium and large. Small, Medium and Large require 1, 2 and 3 robots to push the box respectively. To encourage cooperation between robot agents - they are rewarded more for collecting the larger sized boxes and to encourage effective collection : they are rewarded with a time bonus for collecting boxes quickly.
The Robots are represented by the black circular shape. The Sensors attached to the robot can be seen by the colours blue, red and green which are the long range IR sensors, infrared sensor and ultrasonic sensor respectively. Boxes are represented by yellow squares and the Home Area where boxes need to be dropped off are on the southern end of the simulated environment.

The objective of this assignment was to explore physical output by physicalizing personal data. Swear jars are classic device used to visualize and discourage bad habits. Instead of swearing, my partner and I decided to tackle a more modern issue: using cellphones at the dinner table. Our "No Phones at the Table!" Jar detects when a phone is tilted (i.e. picked up) and activates an apparatus which slowly pushes a preset amount of coins into a jar. The noise of the coins falling serves to remind the offender to put down his phone. If all of the coins have fallen, an angry buzzer sounds as a final warning.


VENICE, Italy (Reuters) - Venice’s mayor declared a state of emergency on Wednesday after “apocalyptic” floods swept through the lagoon city, flooding its historic basilica and inundating squares and centuries-old buildings.
Thoroughfares were turned into raging torrents, stone balustrades were shattered, boats tossed ashore and gondolas smashed against their moorings as the lagoon tide peaked at 187 cm (6ft 2ins) shortly before midnight.
It was the highest level since the record 194 cm set in 1966 but with rising water levels becoming a regular threat to the tourist jewel, city mayor Luigi Brugnaro was quick to blame climate change for the disaster.
“Venice is on its knees,” said Brugnaro. “The damage will run into hundreds of millions of euros.”
“This is the result of climate change,” he said on Twitter.
Related Coverage
The floods, accentuated by driving rains and strong winds, also ravaged areas beyond the city itself.
One man died on Pellestrina, one of the many islands that dot the Venetian lagoon, electrocuted while trying to pump water out of his house.
“Venice has been tortured, but there are also other parts of the Veneto region besides Venice. It is an apocalyptic disaster,” regional governor Luca Zaia told reporters.
He said he was “horrified” by what he was seeing from numerous communities.
Venice’s huge Saint Mark’s Square, once described as Europe’s living room, was submerged by more than one meter of water, while the adjacent Saint Mark’s Basilica was flooded for the sixth time in 1,200 years - but the fourth in the last 20.
“The Basilica is suffering structural damage because the water has risen and so it’s causing irreparable damage,” said Venice Archbishop Francesco Moraglia, warning that ancient mosaics and tiling might have been badly degraded.
“I have never seen anything like it. Venice is a wounded city, but it can’t keep on being wounded every year in the same way,” he said.
More than 80% of Venice was under water when the tide was at its highest and although levels had receded by daybreak further bad weather was expected later in the week, with a series of storms lining up to batter Italy.
A flood barrier was designed in 1984 to protect Venice from high tides, but the multi-billion euro project, known as Mose, has been plagued by the sort of problems that have come to characterize major Italian infrastructure programs — corruption, cost overruns and prolonged delays.
“If Mose had been working, then we would have avoided this exceptional high tide,” Brugnaro said.
Originally expected to start operating in 2011, the city now expects it to be functioning in 2021.
Slideshow (25 Images)
While locals started a clean-up operation, some tourists appeared to enjoy the drama, with one man filmed swimming across Saint Mark’s Square wearing only shorts on Tuesday evening.
The luxury Gritti Palace hotel, a landmark of Venice which looks onto the Lagoon, was also flooded.
The overnight surge triggered several small fires, including one at the International Gallery of Modern Art Ca’ Pesaro, with hundreds of calls to the fire brigade.
“With the rise of sea levels, and an increase in the frequency of sea storms, these extreme phenomena will become ever more numerous,” the head of Italy’s national marine research department. Rosalia Santoleri, told state broadcaster RAI.


The goal
How can we replace a given class’s code with new code at runtime? In particular, how we can we do this while allowing dependency injection and sidestepping assembly versioning issues.
Let’s say you have bunch of classes like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
|
Now let’s assume that you need the ability to modify the behaviour of these classes at runtime without upgrading. And change the dependencies. Without restarting the application.
Old school - The MEF approach (and most other plug-in frameworks)
One approach would be to place each generator in a separate assembly and then you could load them at runtime. (This was my first effort - oh how I struggled).
You can make use of something like MEF to help with the grunt work, but can still be very complex.
One difficulty is the dependencies. The dependencies are often defined in other assemblies and you have to be very careful to avoid ‘dll hell’. It is very easy to get message like:
Could not load file or assembly 'SomeAssembly, Version=<IP_ADDRESS>, Culture=neutral, PublicKeyToken=ad2d246d2bace800' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.
Or even exceptions like
Object (of type 'SomeGenerator') is not of type 'SomeGenerator'.
You either have to write your plug-in code so that it is totally independent (i.e., has no dependencies), or you need to resort to a heap of <bindingRedirect>
tags in your web.config.
Also, with one assembly per format, you can end up with a huge proliferation of assemblies. If you have 50 different formats, that would be 50 assemblies.
New school - The Rosyln approach
An alternative is to use the compiler-as-a-service features of Roslyn.
Can we upload a modified SomeGenerator.cs and get it to reference the deployed assemblies and thereby avoid dll hell? With Roslyn we can do this.
If the compilation fails, we can immediately inform the user that the file is not compatible. If it succeeds, we can use it in lieu of the version that was originally deployed.
Also, you do not need separate assemblies for the plug-ins. Your production code contains, within it somewhere a class named SomeGenerator
. At runtime, we are going to create an in-memory assembly which contains only a single class (still named SomeGenerator
), but which can nevertheless reference any other class available to the original implementation. Then we will get the dependency injection container to ‘replace’ the old generator with the new one.
The plan
- Build an ASP.NET MVC 5 web application. It will use an instance of
HelloWorldGenerator
to generate some output. (This is the original implementation). - Allow a replacement for the
HelloWorldGenerator
class to be uploaded into the application as raw C# code. (This is the plug-in implementation.) - Store the C# code in a database. If the application is restarted, the plug-in code will be reloaded.
- When the output is next requested, compile the new C# class. Any dependencies will be instantiated by the IoC container. If there are any compilation errors, these will be displayed.
- Show that the plug-in class is now being used and the output has changed. The originally shipped
HelloWorldGenerator
class has been replaced by our plug-in. - Delete the plug-in from the table and show the output has reverted to the default (the originally implementation code).
Over next few posts I’ll guide you through building the application and demonstrate the runtime replacement of the generator class.
See Part 2 for screen shots of the working application and an overview of the basic project set up.

Hi,
I am considering buying an emonTx V3 but i first would like to be sure that it is possible to record voltage, current and power factor ? I need these raw data rather than power consumption/production for my project.
Thank by advance for your answers
Re: I need to monitor voltage, current and power factor
If you have a single phase supply and use an ac adapter as a voltage monitor, then you can indeed have rms current and voltage, real and apparent power and from those latter two, power factor (but you won't know whether it is leading or lagging).
If you are on a 3-phase supply, then as the emonTx has only one voltage input, you can have those for one phase, rms current for the second and third phases, but only a good estimate of the p.f. for the second and third phases. (This is because a delayed voltage sample is used for the second and third phases and p.f. in particular will be affected by changes in supply frequency.)
Re: I need to monitor voltage, current and power factor
Thanks for your answer !


RSS-Feeds
Everyone who wants to get informed about updates on websites has to use RSS Feeds. Every time any website you have in your Feed Reader makes an update, you can get instantly a little notice. Its a bit like e-mail, but you have the possibility to stop this service. You can't get spam, as the Feed owner doesn't get an identifier for you.
OpenID
It is really annoying to register on every single page you use. The idea behind OpenID is having one account for registering on many domains. If you want to log-in in Blogger, you are sent to Google. You type in your username and password and Google sends you back to Blogger.
Here is another explanation:
The process seems to be too complex for many users, so Google developed the Google Identity Toolkit (GIT). The technique is really nice, but I don't like the idea that I have to force my users to use Google (or a service of them). Though I use Google for almost everything.
Ajax
Ajax is a programming style. If you like to view another page or get some information which isn't already loaded, you don't have to reload the whole page. The Pages simply display the new content as soon as it has loaded the content. GMail makes heavy use of Ajax.
Hierarchical Labels
Well, I guess this is less a technology than an idea. I think it would be great if labels were used more often. I'd like to sort my personal files with labels, not with folders. The advantage of labels in comparison with folders is that you can add any number of labels to one object (file, e-mail, ...). But you can have a file only in one path if you don't copy the file. So you have to know how the person is thinking, if you want to find the file you are searching for.
Example: You search for a file about you favorite books. Unfortunately, you don't remember if it was an Excel-file or a Word-file. Now you have this tree structure:
- Excel
- Documents
- School
- E-mails
- eBooks
- Math
- School
- Biology
- Chemistry
- English
- Math
- Word
The document you a re searching for could be in Word; in School/English, in Documents/eBooks or in Excel. You you had labels for your files, you could just select the files with a "Books"-label.
I wrote "Hierarchical Labels", because sometimes you have one label, that comes always with another one, but not the other way round. As I am not very interested in chemistry, all files about chemistry were for school. So if I tagged a file with "chemistry" it should automatically get the "school"-tag.
Gravatar
Have you ever noticed blogs or other sites where some people have avatars and others don't? Sometimes, if a possibility to login is provided this is not really amazing. But where does the website get the pictures from if there is no possibility to log in?
Gravatar (an abbreviation for globally recognized avatar) is a service for providing globally-unique avatars. This is good for any website, where you don't have the possibility to store large amounts of data or you don't want to be annoyed with different file types, resizing and users who can't manage to use your software.
Here is a web service, that allows you to quickly see the Gravatars of one e-mail address.


class: center, middle, inverse, title-slide # Lecture 10 ## Intro and Tips for Julia ### Tyler Ransom ### ECON 5253, University of Oklahoma --- # Julia - Julia is scientific computing language - Similar in function to Python, R, or Matlab - Aims to be a "high-level" language that is performant enough for intensive applications - "High-level" in the sense that it doesn't require compilation to run - "Performant" in the sense that it can sometimes run as fast as C, C++ or FORTRAN - ... and can be considerably faster than Python, R or Matlab. --- # Julia speed benchmarks (Source: [julialang.org](https://julialang.org/benchmarks/)) .center[ ![](benchmarks.svg)<!-- --> ] --- # What makes Julia different? - .hi[just in time] (JIT) compilation - .hi[rich type system], which can yield massive performance gains - .hi[multiple dispatch] (i.e. the same function can be reused for different types of inputs) - .hi[metaprogramming] (like macros in Stata) - .hi[loops don't slow you down] (compared to Matlab or R, where they are very slow) --- # Learning Julia - There are lots of resources for learning Julia - Ultimately, learning is through experience - [Julia homepage](https://julialang.org/) - [Documentation](https://docs.julialang.org/en/v1/) - [Julia Discourse](https://discourse.julialang.org/) - [YouTube](https://www.youtube.com/user/JuliaLanguage) - [Cheat sheet](https://juliadocs.github.io/Julia-Cheat-Sheet/) I regularly use all of these resources as I program in Julia --- # Installing Julia Go [here](https://julialang.org/downloads/) and follow the instructions for your computer's operating system --- # Julia REPL REPL = .hi[R]ead .hi[E]val .hi[P]rint .hi[L]oop (i.e. the interactive console) - Open Julia and you should see a prompt that says `julia> ` Stuff the REPL can do: - basic calculator functions; e.g. `sqrt(π)` which returns 1.77245 - up arrow for last command - `;` enters shell mode (where you can issue system commands from inside Julia) - `?` enters help mode, e.g. `?sqrt` - `]` opens package manager; e.g. `] add LinearAlgebra` (note: may [take awhile](https://twitter.com/chrispdanko/status/1256382196895682560?s=20)) --- # Basic operations (see [cheatsheet](https://juliadocs.github.io/Julia-Cheat-Sheet/) for more details) - .hi[Array indexing:] use `[]`, e.g. `X[5,2]` - .hi[Show output:] use `println()`, e.g. `println("size of X is ", size(X))` - .hi[Assignment:] use `=`, e.g. `X = rand(15,3)` - .hi[Commenting:] use `#` for single line, `#= ... =#` for multi-line - .hi[Element-wise operators:] must put a `.` in front, e.g. `x .+ y` if `x` and `y` are arrays - .hi[Load installed package:] `using Random` - .hi[Execute script:] `include("myfile.jl")` `\(\equiv\)` `do myfile.do` or `source('myfile.R')` --- # Creating and executing a Julia script - In Stata or R, you create a script and then execute it - The same thing is true in Julia, but with a slight difference - In Julia, even scripts should have functions wrapped around them - The following is the contents of `myscript.jl` ```julia using <Package1>, <Package2> function scriptwrapper() X = [ones(15,1) rand(15,3)] y = randn(15,1) β = X\y # compute OLS return β end βhat = scriptwrapper() ``` - Then execute this script at the REPL by typing `include("myscript.jl")` --- # Why do I need to wrap everything in a function? - Wrapping code in a function allows the JIT compiler to optimize the code - This is where the speed gains come from - An added benefit is that it [promotes good programming practices](https://twitter.com/tyleransom/status/1227633474733060097?s=20) - Putting everything in a function encourages you to abstract - Abstraction usually leads to performance gains (see p. 22 [here](https://web.stanford.edu/~gentzkow/research/CodeAndData.pdf)) --- # The most common error message you'll receive - Julia is obsessive about types - `1.0` is different from `1` (the former is a `Float64` while the latter is an `Int64`) - This matters: e.g. some functions are optimized to only accept `Int64` types If you type this: `ones(π,1)` You'll get this: ```julia ERROR: MethodError: no method matching ones(::Irrational{:π}, ::Int64) Closest candidates are: ones(::Union{Integer, AbstractUnitRange}...) at array.jl:448 ones(::Type{T}, ::Union{Integer, AbstractUnitRange}...) where T at array.jl:449 Stacktrace: [1] top-level scope at none:0 ``` --- # `MethodError` - The error message on the previous slide is saying that you are violating the rules of the function you're calling - The solution is to read the error message and note that this function requires `Integer` types as inputs - You will also encounter error messages in the following common situations: - You are supplying the wrong number of inputs to a function - You are trying to call a function or object that Julia can't find - (either you haven't loaded a required package, or you haven't called that fn. yet) - To resolve errors, copy the error message into a search engine and see what shows --- # Cool Julia features - My favorite feature is the ability to use Greek symbols in programming - To write these, just simply type the LaTeX code for the symbol and then press Tab - e.g. `\pi`+Tab = `π` - Another cool feature is the `Distributions.jl` package - This package allows a user to specify any desired probability distribution - The user can take draws from it, compute quantiles or probabilities, etc. - You can also double index an object - e.g. `X = rand(15,2)` followed by `X[2,:][2]` (though this example is silly) --- # Comprehensions - Another excellent feature is known as comprehensions - Allows the user in 1 line of code to create an object that could be a complex formula - e.g. computing a present value `\(\sum_{t=1}^T \beta^t Y_t\)` - `PV = sum([β^t*Y[t] for t=1:T])` - Comprehensions allow for much lighter syntax than in other languages --- # Data Input and Output - .hi[Read a CSV file:] `using CSV; data = CSV.read("filename.csv")` - .hi[Write a CSV file:] `using CSV; CSV.write("filename.csv", data)` - .hi[Save a Julia Object:] `using JLD; save("filename.jld", "object_key", object, ...)` - [this is like `.dta` (Stata) or `.rda` (R)] - .hi[Load a Julia Object:] `using JLD; d = load("filename.jld") # Returns a dict` - A `dict` (Dictionary) is a named list of objects [kind of like a `list()` in R] --- # Running a regression - The `CSV` package is usually used in concert with the `DataFrames` package - To run Generalized Linear Model (GLM) regressions, use the `GLM` package ```julia using CSV, DataFrames, GLM, HTTP, CategoricalArrays # load Stata auto dataset (i.e. `sysuse auto` in Stata) url = "https://tyleransom.github.io/teaching/MetricsLabs/auto.csv" auto = CSV.read(HTTP.get(url).body) # set `rep78` variable to be categorical categorical!(auto,:rep78) # run basic regression (`reg price mpg foreign headroom i.rep78` in Stata) lm(@formula(price ~ mpg + foreign + headroom + rep78), auto) ``` - Tip: a function with a `!` after its name means it overwrites its input - This is an overarching Julia convention --- # Piping in Julia - In R, `%>%` can be used to create piping chains - This makes code more readable - e.g. `x %>% mean() %>% log()` instead of `log(mean(x))` - In Julia, you can pipe with `|>`, e.g. `x |> sum |> log` - Note: `|>` is `|` and then `>` (it doesn't show up separately in this font) --- # Where to go from here - [Problem Set 1](https://github.com/OU-PhD-Econometrics/fall-2020/blob/master/ProblemSets/PS1-julia-intro/PS1.pdf) will provide ample opportunity to practice Julia - There are other tips and tricks that you will pick up over time - Either from the [cheatsheet](https://juliadocs.github.io/Julia-Cheat-Sheet/) or on the [Discourse site](https://discourse.julialang.org/) - The Discourse community is really nice, even if (like me) you ask a stupid question - Happy coding!
