In e-commerce, a number of business process and activities go unnoticed by the consumer
and are often taken for granted. With an online merchant's business, value-added activities work
together to make the business-to-consumer interface operational.
In 1985 Michael Porter wrote a book called Competitive Advantage, in which he introduced
the concept of the value chain. Businesses receive raw materials as input, add value to them
through various processes, and sell the finished product as output to customers.
[1]Competitive advantage is achieved when an organization links the activities in its value
chain more cheaply and more effectively than its competitors. For example, the purchasing function
assists the production activity to ensure that raw materials and other supplies are available on time
and meet the requirements of the products to be manufactured. The manufacturing function, in turn,
has the responsibility to produce quality products that the sales staff can depend on. The human
resource function must hire, retain, and develop the right personnel to ensure continuity in
manufacturing, sale, and other areas of the business. Bringing in qualified people contributes to
stability, continuity, and integrity of operations throughout the firm.
[2]There is no time sequence or special sequence of activities before a business is considered
successful or effective. The idea is to link different activities in such a way that the value-added
(output) of one activity (department, process, etc.) contributes to the input of another activity.
The integration of these activities results in an organization fine-tuned for profitability and
growth.
According to Porter, the primary activities of a business are:
Inbound logistics. These are procurement activities vendor selection, comparative shopping,
negotiating supply contracts, and just-in-time arrival of goods. They represent the supply side of
the business. In e-commerce, the business must be capable of exchanging data with suppliers
quickly, regardless of the electronic format.
Operations. This is the actual conversion of raw materials received into finished products. It
includes fabrication, assembly, testing, and packaging the product. This production activity
provides added value for the marketing function. Operational activities are the point in the value
chain where the value is added. These happen in the back-office where the pizza is baked, the
PCs are assembled, or the stock trades are executed. Data are shared at maximum network speed
among internal and external partners involved in the value-adding processes.
Outbound logistics. This activity represents the actual storing, distributing, and shipping of
the final product. It involves warehousing, materials handling, shipping, and timely delivery to
the ultimate retailer or customer. The output of this activity ties in directly with marketing and
sales.
Marketing and sales. This activity deals with the ultimate customer. It includes advertising,
product promotion, sales management, identifying the product's customer base, and distribution
channels. The output of this activity could trigger increased production, more advertising, etc.
Service. This activity focuses on after-sale service to the customer. It includes testing,
maintenance, repairs, warranty work, and replacement parts. The output of this activity means
satisfied customers, improved image of the product and the business, and potential for increased
production, sale, etc.
Primary activities are not enough. A business unit needs support activities to make sure the
primary activities are carried out. Imagine, for example, a manufacturing concerns with no
people or with poorly skilled employees.
The key support activities in the value chain are:
Corporate infrastructure. This activity is the backbone of the business unit. It includes general
management, accounting, finance, planning, and legal services. It is most often pictured in an
organization chart showing the relationship among the different positions, the communication
network, and the authority structure. Obviously, each position holder must add value to those above
as well as below.
Human resources. This is the unique activity of matching the right people to the job. It
involves recruitment, retention, career path development, compensation, training and development,
and benefits administration. The output of this activity affects virtually every other activity in the
company.
Technology development. This activity adds value in the way it improves the product and
the business processes in the primary activities. The output of this activity contributes to the
product quality, integrity, and reliability, which make life easier for the sales force and for
customer relations.
Procurement. This activity focuses on the purchasing function and how well it ensures the
availability of quality raw material for production.
Where does e-commerce fit in? The value chain is a useful way of looking at a corporation's
activities and how the various activities add value to other activities and to the company in
general.
[3]E-commerce can play a key role in reducing costs, improving product quality and
integrity, promoting a loyal customer base, and creating a quick and efficient way of selling
products and services. By examining the elements of the value chain, corporate executives can
look at ways of incorporating information technology and telecommunications to improve the
overall productivity of the firm. Companies that do their homework early and well ensure
themselves a competitive advantage in the marketplace.

Select this option if you want to run the output LLVM IR through "c++filt", which converts 'mangled' C++ names to their unmangled version. Note that LLVM code produced will not be lexically valid, but it will be easier to understand.
Select this option to run the LLVM link-time optimizer, which is designed to optimize across files in your application. Since the demo page doesn't allow you to upload multiple files at once, and does not link in any libraries, we configured the demo page optimizer to assume there are no calls coming in from outside the source file, allowing it to optimize more aggressively.
Note that you have to define 'main' in your program for this to make much of a difference.

Cooking time

Serves 4
Veal kidneys are a French favourite that are best served rare - not slowly braised as you would usually cook beef kidneys.
For the pilau rice, heat the butter and olive oil in a large pan over a medium heat. Add the onion and garlic and fry for 2-3 minutes, or until softened. Add the rice and stir well to coat. Pour in the stock, stir well and then bring the mixture to the boil.
Reduce the heat until the liquid is simmering. Cover the pan with a lid or aluminium foil and continue to simmer for 15-18 minutes, until the rice has absorbed the stock and is tender. Season, to taste, with salt and pepper.
For the veal kidneys, carefully cut away the surrounding fat on the kidneys, then turn them upside down to reveal the fatty sinews. With the point of a sharp knife, cut around the sinews so the kidneys come away clean. Divide the kidneys into bite sized pieces, following the natural lobes as much as possible.
In a heavy-based frying pan, heat a little olive oil until smoking hot. Add the kidneys and season lightly with salt and pepper. Cook for 3-4 minutes (depending on size), turning the kidneys to seal all over. Tip into a colander to drain. The kidneys should still be very pink when they finish cooking in the sauce.
In the same pan, gently fry the shallots in the butter over a medium heat, stirring frequently, for 5 minutes without letting them colour. Increase the heat, add the brandy and cook until the volume of liquid is reduced by half. Add the wine and again reduce by half. Add the cream and reduce to a light sauce. Remove from the heat and whisk in all the mustards. Reheat gently, do not boil or it will become bitter. Add the kidneys and heat through.
To serve, melt the butter in a sauté pan. Add the garlic and fry for 1-2 minutes, then add the spinach and cook until wilted. You might need to add 1-2 tablespoons of water if the spinach starts to stick to the pan.
Serve the kidneys, rice and wilted spinach in shallow serving bowls with the sauce poured over the kidneys.

Court suspends ruling on 'unlawful' Hong Kong mask ban for seven days
HONG KONG: Hong Kong police can continue enforcing a ban on demonstrators wearing masks for the next seven days, the High Court said on Friday (Nov 22), to allow the government time to appeal an earlier ruling that the action was unconstitutional.
The ban was imposed in October by the city's pro-Beijing leader Carrie Lam under colonial-era emergency powers not used in more than half a century.
It was aimed at quelling months of unrest sparked by concerns that Beijing was tightening its grip on Hong Kong, but instead triggered fresh protests by demonstrators who said the ban merely underlined their fears.
The High Court earlier this week had ruled the ban to be unlawful, but the government asked for a suspension of the ruling.
READ: Hong Kong High Court rules emergency law banning face masks unconstitutional
The court said on Friday it had rejected the government's request for a longer suspension and decided instead upon a short stay of its ruling due to the "great public importance of the issues raised in this case, and the highly exceptional circumstances that Hong Kong is currently facing".
Protesters have used face masks to avoid identification and respirators to protect themselves from tear gas.
The new law threatens anyone wearing masks at protests with up to a year in prison.
In its original ruling against the ban, the court had said "the restrictions it imposes on fundamental rights ... go further than is reasonably necessary".
Demonstrators - most of them wearing masks - have continued to clash with police, often violently, as they press demands for greater democracy as well as an independent inquiry into alleged police brutality.
READ: 77 people arrested in Hong Kong for violating anti-mask law: Police
Pro-democracy politician Dennis Kwok, who was among 24 lawmakers who initiated the judicial review against the ban, expressed disappointment with the suspension.
"We say that if a law has already been declared unconstitutional and violating the basic human rights of the Hong Kong people, it should not be enforced at all - not even one day, not even one second," he said on the floor of the Legislative Council.
But he welcomed the court's refusal to grant a longer suspension and called on the government to "drop this anti-mask law, drop all prosecutions and focus on finding a political solution for the political crisis that is facing the Hong Kong people".

Eric Cheung, a legal scholar at the University of Hong Kong, told AFP that any arrests made in the coming week could be invalidated if the ban is ultimately found to be unconstitutional.
Cheung added that if the ban is ultimately determined to be unlawful, police could be held accountable for making illegal arrests.

2020. Presentation I gave to 200+ Entergy interns on the topic "How to Effectively Work Remotely"
2018-2019. I was an active member of a coworking space in New Orleans called The Blue House, where I helped lead discussions about web technologies, Bitcoin and the blockchain ecosystem, and how tech may help aid in increasing awareness of civic issues. Many of these conversations led to work on the Mixed Media project
2016 - 2017. With the help of my colleage Joe, I partnered up with some folks at Education First in Cambridge and hosted several Designers & Geeks events. I mostly emcee'd, made sure everyone had a good time, and tried to connect folks.

08. Restoring Blockchain Identity
Restore your Wallet Identity
We’ve all forgotten passwords from time to time, and no one is immune from password horror stories!
There are times you may end up needing to restore your wallet identity.
This could happen for a few reasons
- You might forget your password.
- You could lose the 2-step verification device.
- The wallet service might even become unavailable.
- It’s also possible that you lose your computer or it gets stolen.
Hopefully none of these things happen, but it’s important to be ready just in case!
To help prepare for situations like this, it’s helpful to know how to restore your bitcoin wallet.
Ways to Restore a Wallet
If you ever need to restore your wallet, there are 2 ways to do it. You can do it with the wallet words you saved, or with the private keys from when you first created your wallet.
Use a Seed
One way to restore a wallet is using a seed. The ‘seed’ is the 12 words you were given when creating your wallet. If you can remember these words, you can use them to restore your wallet!
The benefit of restoring your identity using the seed is that it can be much simpler than using the private key. It's easier to remember a list of words than a random string of numbers and letters.
The hardest part to any of this is safely storing or remembering this information for when you need it. Anybody else who discovers the list of words can access the wallet and any funds tied to it.
So be VERY careful!
Use a Private Key
Another way to restore a wallet is with a private key.
When restoring a wallet using a private key, there are 2 ways to do it. You can either import or sweep this key, and it’s useful to understand the difference.
Import a Private Key
When importing a private key, you'll have a source wallet and a destination wallet. The destination wallet is likely filled with a group of private keys already. To import the key you move the private key from the source wallet to the destination wallet.
This results in you getting access to both the source wallet AND the destination wallet.
The downside to importing is that the private key from the source wallet is essentially compromised since it was shared. If someone gets access to the private key from the source wallet, they can access those bitcoins.
See more on how to import a private key at BitcoinElectrum.com.
Sweep a Private Key
When you sweep a private key, you add a private key from a source wallet into the destination wallet. All the bitcoins that belong to that private key are swept from the source wallet over into the destination wallet.
This is a little different than importing because it completely removes the funds from the original wallet. You’ll now only be using this new wallet to make future transactions.
See more on how to sweep a private key at BitcoinElectrum.com.
Which should you choose?
Why would you import or sweep a private key?
Sweep a wallet if you're worried about wallet security.This might happen in the case that you think someone might have access to your private key. Sweeping completely cleans out the wallet so that no one will have access to your bitcoins.
If you are certain no one has gotten access to your private key, and that no one ever will, then you can import the key instead. This is useful in cases where you need the funds to be available from multiple wallets.
When in doubt, stick with sweeping. It’s more secure this way, and it avoids some problems that are associated with importing a wallet.

‘Flirty Dancing’ Is A Blind Dating Show W/ Choreographed Routines & Fuck, It’s Mesmerising
by By Louis HansonWant your cold, usually-dormant heart to feel something again? Keen to remind yourself that you’re capable of feeling anything other than horniness and weekly existential crises? Well, please, look no further than Flirty Dancing, one of the most joyous UK dating shows that happens to exist on this planet Earth.
Flirty Dancing is a blind dating show in which romantic hopefuls separately learn choreography to a dance, only to meet for the first time when they perform the routine together.
The program, which is heading into its second season, has received some much-deserved attention over the past day or so after going absolutely viral on Twitter… primarily thanks to this routine below. Garry and Ryan, take it away, you beautiful, beautiful souls.
The joy in their faces. Their piercing eye contact with one another. Their sheer elation as they conclude the piece. I’m actually crying.
This clip achieved so much viral success that host (and absolute snacc of a human) Ashley Banjo shared his gratitude. “When I watch Gary and Ryan dance it absolutely reaffirms to me that love is love!”
Although we aren’t sure if Garry and Ryan remain an item today, some trusty internet sleuths downloaded the episode and found that they’d gone on a few dates after their sacred dance.
*SCREAM CRIES IN GAY*
Now, let’s cry some more together, shall we?
BRB, this is me for the next 7 hours…

Not sure if this is possible, but it would be really nice if the Battle report screen had a total for Ribbons accumulated during the course of a round.
For instance, during a round you might obtain 5 Resupply ribbons, but on the report screen it only show a single ribbon. Anyway to add like the total number obtained in the round in parenthesis over the single ribbon that is shown.
Ex: (5)
Thanks for your work on this plugin... I love it, I especially like this latest update that incorporates BF3stats.com into Battlelog....nicely done !

| void StarNetwork::addNode |
( |
StarNode * |
node | ) |
|
Adds node node to the internal data structure.
- Note
- Node is assumed to have out-going links that must be added after node addition, using method addLink(). This method might throw an error.
| bool StarNetwork::assignLinkFlow |
( |
int |
nodeFrom, |
|
|
int |
nodeTo, |
|
|
FPType |
flow |
|
) |
| |
|
private |
This method is used in loadFromFile(). It attempts to load link flow \ flow to a link with nodes nodeFrom and nodeTo. If such link does not exists false is returned.
| StarLink * StarNetwork::beginLink |
( |
| ) |
const |
This method must be used together with getNextLink() method.
- Warning
- it is not safe to use this method in a nested loop when this method is called more than once on the same object.
| StarNode * StarNetwork::beginNode |
( |
| ) |
const |
- Returns
- pointer to the first node. It must be used together with getNextNode() method. For example, the entire forward star network can be iterated as follows:
- Warning
- it is not safe to use this method in a nested loop when this method is called more than once on the same object.

| int StarNetwork::getNodeIndex |
( |
int |
id | ) |
|
- Returns
- internal index of a node specified by its ID
- Note
- Avoid calling this function as much as possible. It has average case complexity: constant, worst case complexity: linear in container size.
| StarNode * StarNetwork::getNodeWithLinks |
( |
int |
index | ) |
|
- Returns
- a pointer of type StarNode* to a node specified by index index. However, nodes of this type are created only if they have out-going links. That's why only such node can be returned by this method. If another node is attempted to get by using this method, then NULL is returned.
| void StarNetwork::linkNodes |
( |
| ) |
|
This method must be called once after all links and nodes were added to the network. It create internal indexes (all internal indexes follow the convention that it is a number between 0 and number of nodes, or number of links for node and link indexes respectively) for all nodes and sets them appropriately.
| void StarNetwork::loadFromFile |
( |
const std::string & |
fileName | ) |
|
Loads link flows from file specified by fileName (link travel times are recalculated). File format is: nodeFrom nodeTo linkFlow travelTime

--- layout: post title: "Satisfyr – useful little addition to my testing" comments: true ---
I use a tool called Satisfyr. This tool helps me to keep to the 1 assert per test rule. It is a way to perform lambda-based assertions from within tests. It is written by Daniel Cazzulino (developer of World of VS and Moq to name a few things).
I use Satisfyr when I am testing translations between DTO and Business objects that go through an automapper layer. This allows me to turn this:
into this:
Its just syntactical sugar but it helps me to assert that an object is correct - this includes its properties etc. Hope it helps.


public override void OnData(Slice slice) { if (slice.ContainsKey(_symbol)) { var myData = slice[_symbol]; } }
def OnData(self, slice: Slice) -> None: if slice.ContainsKey(self.symbol): my_data = slice[self.symbol]
The OnData
method is the primary event handler for receiving financial data events to your algorithm. It is triggered sequentially at the point in time the data is available; in backtesting and live. For daily data this means the event is processed at midnight in backtesting or 6am the following day in live trading.
All data for a given moment of time is grouped in a single event, including custom data types. This data is passed with the Slice object.
When fill-forward is enabled for your asset, the OnData event handler will be called regularly even if there was no new data. This is the default behavior.
In backtesting, if your algorithm takes a long time to process a slice, the following slice objects queue up and the next event triggers when your algorithm finishes processing the current slice. In live trading, if your algorithm takes longer to process the current slice than the time period that the slice spans, the next event triggers when your algorithm finishes processing the current slice, but the slice of the following event is the most recent slice. For example, say your algorithm consumes second resolution Crypto data but it takes your algorithm 3.5 seconds to process each slice. In backtesting, you'll get every slice. In live trading, if you deploy at 12:00:00 AM Coordinated Universal Time (UTC), you'll get the first slice at 12:00:01 AM UTC (spanning 12:00:00 AM UTC to 12:00:01 AM UTC) and you'll get the second slice at 12:00:04.5 AM UTC (roughly spanning 12:00:03 AM UTC to 12:00:04 AM UTC).
To perform intensive computation before the market opens, use a Scheduled Event or the Train method.
For more information on the Slice
object and OnData event, see Handling Data.

For a reasonably sane & productive member of society (arguable, but let’s not complicate things), I’m far too mobile and unrooted. I travel quite a bit for a job that is simultaneously my greatest privilege and my worst burden.
So I write. And I write. Travel pieces, political journalism (a stretch from ranting but, still), short stories, poetry and other such riff-raff. I contribute to a handful of publications and will probably just keep going until something gives out, or someone gives in.
Yeah.


The zip file system provider introduced in the JDK 7 release is an implementation of a custom file system provider. The zip file system provider treats a zip or JAR file as a file system and provides the ability to manipulate the contents of the file. The zip file system provider creates multiple file systems — one file system for each zip or JAR file.
The demo/nio/zipfs/src.zip
file in demo and samples
,which can be downloaded explicitly from
Demo and Samples contains the source code for the zip file system
provider. It also contains the Demo.java
class that
shows how to use the zip file system provider.
You can use the factory methods of the java.nio.file.FileSystems
class to create a new zip file system or to obtain a reference to
an existing zip file system. Create a zip file system by specifying
the path of the zip or JAR file in one of the following ways:
java.net.JarURLConnection
class
URI uri = URI.create("jar:file:/codeSamples/zipfs/zipfstest.zip"); FileSystem fs = FileSystems.newFileSystem(uri, env);
Path zipfile = Paths.get("/codeSamples/zipfs/zipfstest.zip"); FileSystem fs = FileSystems.newFileSystem(zipfile, env, null);
Specify the configuration options for the zip file system in the
java.util.Map
object passed to the
FileSystems.newFileSystem
method. See the Zip File System Properties
topic for information about the provider-specific configuration
properties for the zip file system.
Once you have an instance of a zip file system, you can invoke
the methods of the java.nio.file.FileSystem
and java.nio.file.Path
classes to perform operations such as copying, moving, and renaming
files, as well as modifying file attributes.
The following code sample shows how to create a zip file system and copy a file to the new zip file system.
import java.util.*; import java.net.URI; import java.nio.file.Path; import java.nio.file.*; public class ZipFSPUser { public static void main(String [] args) throws Throwable { Map<String, String> env = new HashMap<>(); env.put("create", "true"); // locate file system by using the syntax // defined in java.net.JarURLConnection URI uri = URI.create("jar:file:/codeSamples/zipfs/zipfstest.zip"); try (FileSystem zipfs = FileSystems.newFileSystem(uri, env)) { Path externalTxtFile = Paths.get("/codeSamples/zipfs/SomeTextFile.txt"); Path pathInZipfile = zipfs.getPath("/SomeTextFile.txt"); // copy a file into the zip file Files.copy( externalTxtFile,pathInZipfile, StandardCopyOption.REPLACE_EXISTING ); } } }


iDuprey.com enjoyed another hiatus from the internet on Saturday due to a power outage. A very large tree decided to rest on our power lines in the back yard. It took them all day to remove the tree and turn the power back on. We fired up the generator to keep us warm, but the site did not rank so high to deserve electricity too. Power was lost around 11 AM on Saturday and returned around 11 PM. Lets hope we have no more interruptions for a while. The power crew ripped the cable line off our house and left it lying on the ground. Fortunately, this did not impact our cable or internet service. We will be filing a complaint with RG&E later this week.
I'll post some interesting pictures of the tree later.

https://leetcode.com/problems/jump-game-ii/
Given an array of non-negative integers, you are initially positioned at the first index of the array. Each element in the array represents your maximum jump length at that position. Your goal is to reach the last index in the minimum number of jumps. Example: Input: [2,3,1,1,4] Output: 2 Explanation: The minimum number of jumps to reach the last index is 2. Jump 1 step from index 0 to 1, then 3 steps to the last index. Note: You can assume that you can always reach the last index.
class Solution { public: string add(string num1, string num2){
class Solution { public: int jump(vector& nums) { vector minStep; for (int i = 0; i < nums.size(); i ++){ minStep.push_back(-1); } minStep[0] = 0; for (int i = 0; i < nums.size(); i ++){ int maxStep = nums[i]; int thisStep = minStep[i]; for (int j = 1; j <= maxStep; j ++){ if (i + j < nums.size()){ if (minStep[i + j] == -1) minStep[i+j] = thisStep +1; else{ if (thisStep +1 < minStep[i+j]) minStep[j+j] = thisStep +1; } } } } return minStep[minStep.size() -1]; } };

is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.

Gandhi (1982)
Grade: 65
The life of Mahatma Gandhi is inspirationally depicted in this three hour plus biography, which won an incredible eight Academy Awards. Ben Kingsley was plucked from obscurity by director Richard Attenborough to play the legendary spiritual leader, a proponent of Indian independence, religious harmony, and nonviolence.
The film takes place over a half century, with Gandhi's aging made fully credible by outstanding makeup and costumes. The story begins with Gandhi as a young lawyer in South Africa, where his status as an Indian makes him subject to Apartheid laws. Gandhi develops his philosophy of nonviolent resistance to authority, which makes him a hero in the cause of Indian independence from England.
Most of the many characters in this lengthy epic can be put into four different categories. There are the segregationalist Western politicians, alternately smug and despairing. There are the pro-independence Hindu activists and politicians, who must be taught nonviolence by Gandhi. There are Western press and clergy who are sympathetic to Gandhi's cause. And there are Gandhi's devoted followers, most notably his wife (Rohini Hattangady) and adopted daughter (Geraldine James). Ironically, in a film whose theme is that everyone is equal, the famous actors of European descent with small roles are given top billing over Indian actors with larger parts.
The problem with making a film about heroes is the difficulty in presenting them as human beings, complete with flaws. Any eccentricities that they have must be lovable, such as Gandhi's insistence upon adopting the dress and lifestyle of an Indian peasant. Attenborough attempts to humanize Gandhi by presenting a heated argument with his wife, in which he orders her to leave the commune because she won't clean toilets. But the spat is immediately settled, the wife happily reconciled and relenting, and the behavior of both is saintly thereafter.
There is also a natural tendency to portray the British as arrogant snobs. This is often avoided by Attenborough, but he sometimes slips: John Gielgud is a sneering blueblood, and a needless scene is inserted with preppy cricket players. But the religious hatred between Hindus and Moslems is realistically presented, with the resulting sorrow of the aging Indian independence leaders effective and credible.
In a film with a running time of 188 minutes, there are bound to be some slow moments. Gandhi and wife repeat their wedding ceremony for a reporter, and the wife's death is drawn out. On the other hand, the scenes with Gandhi fasting are well done.
Richard Attenborough was most famous as an actor prior to making "Gandhi", a project which he had been pushing for years prior to production. He directed "Cry Freedom" a few years later, a film with similar themes involving South African civil rights activist and martyr Steven Biko. Attenborough has also continued his acting career, including a memorable character in "Jurassic Park".
Perhaps due more to its values than its actual quality, "Gandhi" won a mountain of Academy Awards, including Best Picture, Best Director, Best Actor (Kingsley), Best Original Screeplay (John Briley), Best Cinematography (Billy Williams and Ronnie Taylor), Best Editing (John Bloom), Best Art Direction and Best Costume Design.

Written statement to Parliament
Written ministerial statement by the Secretary of State for Education Nicky Morgan on the School Teachers' Review Body's 25th report.
The 25th report of the School Teachers’ Review Body ( STRB ) is being published today. Its recommendations cover the remit that I issued in September 2014. The report contains recommendations on how to apply the pay award for teachers that is due to be implemented from September 2015. Copies of the STRB ’s 25th Report are available in the Vote Office, the Printed Paper Office and the Libraries of the House, and online at www.gov.uk.
The STRB has recommended an increase from September 2015 of 1% to the minima of all the pay ranges and allowances in the national pay framework, including the:
It has also recommended an increase of 1% to the maxima of all the pay ranges and allowances, except the main pay range, the leadership pay range and the 8 headteacher group pay ranges. It has proposed an uplift of 2% to the maxima of the main pay range and no uplift to the maxima of the leadership pay range or the maxima of the 8 headteacher group pay ranges.
A full list of the recommendations is attached as an annex.
My officials will write to all of the statutory consultees of the STRB to invite them to contribute to a consultation on my acceptance of these recommendations. The consultation will last for 6 weeks.
I am grateful to the STRB for these recommendations and, subject to the views of consultees, I intend to accept all the key recommendations.
My detailed response contains further information on these matters.
School Teachers’ Review Body’s ( STRB ’s) recommendations and response from the Secretary of State for Education (Nicky Morgan).
[The following sets out the full set of recommendations from the STRB as published in the 25th report on 12 March 2015, together with the response from the Secretary of State for Education.]
The Secretary of State for Education (Nicky Morgan): The 25th Report of the STRB is being published today. It covers matters referred to the STRB in September 2014. Copies are available in the Vote Office, the Printed Paper Office and in the Libraries of the House and online at www.gov.uk.

13 Distribution Protocol
This description is far from complete. It will be updated if the protocol is updated. However, the protocols, both from Erlang nodes to the Erlang Port Mapper Daemon (EPMD) and between Erlang nodes are stable since many years.
The distribution protocol can be divided into four parts:
-
Low-level socket connection (1)
-
Handshake, interchange node name, and authenticate (2)
-
Authentication (done by net_kernel(3)) (3)
-
Connected (4)
A node fetches the port number of another node through the EPMD (at the other host) to initiate a connection request.
For each host, where a distributed Erlang node is running, also an EPMD is to be running. The EPMD can be started explicitly or automatically as a result of the Erlang node startup.
By default the EPMD listens on port 4369.
(3) and (4) above are performed at the same level but the net_kernel disconnects the other node if it communicates using an invalid cookie (after 1 second).
The integers in all multibyte fields are in big-endian order.
The Erlang Distribution protocol is not by itself secure and does not aim to be so. In order to get secure distribution the distributed nodes should be configured to use distribution over tls. See the Using SSL for Erlang Distribution User's Guide for details on how to setup a secure distributed node.
13.1 EPMD Protocol
The requests served by the EPMD are summarized in the following figure.
Each request *_REQ is preceded by a 2 byte length field. Thus, the overall request format is as follows:
| 2 | n |
| Length | Request |
Register a Node in EPMD
When a distributed node is started it registers itself in the EPMD. The message ALIVE2_REQ described below is sent from the node to the EPMD. The response from the EPMD is ALIVE2_RESP.
| 1 | 2 | 1 | 1 | 2 | 2 | 2 | Nlen | 2 | Elen |
| 120 | PortNo | NodeType | Protocol | HighestVersion | LowestVersion | Nlen | NodeName | Elen | Extra |
- PortNo
-
The port number on which the node accept connection requests.
- NodeType
-
77 = normal Erlang node, 72 = hidden node (C-node), ...
- Protocol
-
0 = TCP/IPv4, ...
- HighestVersion
-
The highest distribution version that this node can handle. The value in Erlang/OTP R6B and later is 5.
- LowestVersion
-
The lowest distribution version that this node can handle. The value in Erlang/OTP R6B and later is 5.
- Nlen
-
The length (in bytes) of field NodeName.
- NodeName
-
The node name as an UTF-8 encoded string of Nlen bytes.
- Elen
-
The length of field Extra.
- Extra
-
Extra field of Elen bytes.
The connection created to the EPMD must be kept as long as the node is a distributed node. When the connection is closed, the node is automatically unregistered from the EPMD.
The response message ALIVE2_RESP is as follows:
| 1 | 1 | 2 |
| 121 | Result | Creation |
Result = 0 -> ok, result > 0 -> error.
Unregister a Node from EPMD
A node unregisters itself from the EPMD by closing the TCP connection to EPMD established when the node was registered.
Get the Distribution Port of Another Node
When one node wants to connect to another node it starts with a PORT_PLEASE2_REQ request to the EPMD on the host where the node resides to get the distribution port that the node listens to.
| 1 | N |
| 122 | NodeName |
where N = Length - 1.
| 1 | 1 |
| 119 | Result |
or
| 1 | 1 | 2 | 1 | 1 | 2 | 2 | 2 | Nlen | 2 | Elen |
| 119 | Result | PortNo | NodeType | Protocol | HighestVersion | LowestVersion | Nlen | NodeName | Elen | >Extra |
If Result > 0, the packet only consists of [119, Result].
The EPMD closes the socket when it has sent the information.
Get All Registered Names from EPMD
This request is used through the Erlang function net_adm:names/1,2. A TCP connection is opened to the EPMD and this request is sent.
| 1 |
| 110 |
The response for a NAMES_REQ is as follows:
| 4 | |
| EPMDPortNo | NodeInfo* |
NodeInfo is a string written for each active node. When all NodeInfo has been written the connection is closed by the EPMD.
NodeInfo is, as expressed in Erlang:
io:format("name ~ts at port ~p~n", [NodeName, Port]).
Dump All Data from EPMD
This request is not really used, it is to be regarded as a debug feature.
| 1 |
| 100 |
The response for a DUMP_REQ is as follows:
| 4 | |
| EPMDPortNo | NodeInfo* |
NodeInfo is a string written for each node kept in the EPMD. When all NodeInfo has been written the connection is closed by the EPMD.
NodeInfo is, as expressed in Erlang:
io:format("active name ~ts at port ~p, fd = ~p~n", [NodeName, Port, Fd]).
or
io:format("old/unused name ~ts at port ~p, fd = ~p ~n", [NodeName, Port, Fd]).
Kill EPMD
This request kills the running EPMD. It is almost never used.
| 1 |
| 107 |
The response for a KILL_REQ is as follows:
| 2 |
| OKString |
where OKString is "OK".
STOP_REQ (Not Used)
| 1 | n |
| 115 | NodeName |
where n = Length - 1.
The current implementation of Erlang does not care if the connection to the EPMD is broken.
The response for a STOP_REQ is as follows:
| 7 |
| OKString |
where OKString is "STOPPED".
A negative response can look as follows:
| 7 |
| NOKString |
where NOKString is "NOEXIST".
13.2 Distribution Handshake
This section describes the distribution handshake protocol introduced in Erlang/OTP R6. This description was previously located in $ERL_TOP/lib/kernel/internal_doc/distribution_handshake.txt and has more or less been copied and "formatted" here. It has been almost unchanged since 1999, but the handshake has not changed much since then either.
General
The TCP/IP distribution uses a handshake that expects a connection-based protocol, that is, the protocol does not include any authentication after the handshake procedure.
This is not entirely safe, as it is vulnerable against takeover attacks, but it is a tradeoff between fair safety and performance.
The cookies are never sent in cleartext and the handshake procedure expects the client (called A) to be the first one to prove that it can generate a sufficient digest. The digest is generated with the MD5 message digest algorithm and the challenges are expected to be random numbers.
Definitions
A challenge is a 32-bit integer in big-endian order. Below the function gen_challenge() returns a random 32-bit integer used as a challenge.
A digest is a (16 bytes) MD5 hash of the challenge (as text) concatenated with the cookie (as text). Below, the function gen_digest(Challenge, Cookie) generates a digest as described above.
An out_cookie is the cookie used in outgoing communication to a certain node, so that A's out_cookie for B is to correspond with B's in_cookie for A and conversely. A's out_cookie for B and A's in_cookie for B need not be the same. Below the function out_cookie(Node) returns the current node's out_cookie for Node.
An in_cookie is the cookie expected to be used by another node when communicating with us, so that A's in_cookie for B corresponds with B's out_cookie for A. Below the function in_cookie(Node) returns the current node's in_cookie for Node.
The cookies are text strings that can be viewed as passwords.
Every message in the handshake starts with a 16-bit big-endian integer, which contains the message length (not counting the two initial bytes). In Erlang this corresponds to option {packet, 2} in gen_tcp(3). Notice that after the handshake, the distribution switches to 4 byte packet headers.
The Handshake in Detail
Imagine two nodes, A that initiates the handshake and B that accepts the connection.
- 1) connect/accept
-
A connects to B through TCP/IP and B accepts the connection.
- 2) send_name/receive_name
-
A sends an initial identification to B, which receives the message. The message looks as follows (every "square" is one byte and the packet header is removed):
+---+--------+--------+-----+-----+-----+-----+-----+-----+-...-+-----+ |'n'|Version0|Version1|Flag0|Flag1|Flag2|Flag3|Name0|Name1| ... |NameN| +---+--------+--------+-----+-----+-----+-----+-----+-----+-... +-----+
'n' is the message tag. 'Version0' and 'Version1' is the distribution version selected by A, based on information from the EPMD. (16-bit big-endian) 'Flag0' ... 'Flag3' are capability flags, the capabilities are defined in $ERL_TOP/lib/kernel/include/dist.hrl. (32-bit big-endian) 'Name0' ... 'NameN' is the full node name of A, as a string of bytes (the packet length denotes how long it is).
- 3) recv_status/send_status
-
B sends a status message to A, which indicates if the connection is allowed. The following status codes are defined:
- ok
-
The handshake will continue.
- ok_simultaneous
-
The handshake will continue, but A is informed that B has another ongoing connection attempt that will be shut down (simultaneous connect where A's name is greater than B's name, compared literally).
- nok
-
The handshake will not continue, as B already has an ongoing handshake, which it itself has initiated (simultaneous connect where B's name is greater than A's).
- not_allowed
-
The connection is disallowed for some (unspecified) security reason.
- alive
-
A connection to the node is already active, which either means that node A is confused or that the TCP connection breakdown of a previous node with this name has not yet reached node B. See step 3B below.
The format of the status message is as follows:
+---+-------+-------+-...-+-------+ |'s'|Status0|Status1| ... |StatusN| +---+-------+-------+-...-+-------+
's' is the message tag. 'Status0' ... 'StatusN' is the status as a string (not terminated).
- 3B) send_status/recv_status
-
If status was alive, node A answers with another status message containing either true, which means that the connection is to continue (the old connection from this node is broken), or false, which means that the connection is to be closed (the connection attempt was a mistake.
- 4) recv_challenge/send_challenge
-
If the status was ok or ok_simultaneous, the handshake continues with B sending A another message, the challenge. The challenge contains the same type of information as the "name" message initially sent from A to B, plus a 32-bit challenge:
+---+--------+--------+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-...-+-----+ |'n'|Version0|Version1|Flag0|Flag1|Flag2|Flag3|Chal0|Chal1|Chal2|Chal3|Name0|Name1| ... |NameN| +---+--------+--------+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-... +-----+
'Chal0' ... 'Chal3' is the challenge as a 32-bit big-endian integer and the other fields are B's version, flags, and full node name.
- 5) send_challenge_reply/recv_challenge_reply
-
Now A has generated a digest and its own challenge. Those are sent together in a package to B:
+---+-----+-----+-----+-----+-----+-----+-----+-----+-...-+------+ |'r'|Chal0|Chal1|Chal2|Chal3|Dige0|Dige1|Dige2|Dige3| ... |Dige15| +---+-----+-----+-----+-----+-----+-----+-----+-----+-...-+------+
'r' is the tag. 'Chal0' ... 'Chal3' is A's challenge for B to handle. 'Dige0' ... 'Dige15' is the digest that A constructed from the challenge B sent in the previous step.
- 6) recv_challenge_ack/send_challenge_ack
-
B checks that the digest received from A is correct and generates a digest from the challenge received from A. The digest is then sent to A. The message is as follows:
+---+-----+-----+-----+-----+-...-+------+ |'a'|Dige0|Dige1|Dige2|Dige3| ... |Dige15| +---+-----+-----+-----+-----+-...-+------+
'a' is the tag. 'Dige0' ... 'Dige15' is the digest calculated by B for A's challenge.
- 7) check
-
A checks the digest from B and the connection is up.

Use the SEND_SENDER control message instead of the SEND control message and use the SEND_SENDER_TT control message instead of the SEND_TT control message.
There is also function dist_util:strict_order_flags/0 returning all flags (bitwise or:ed together) corresponding to features that require strict ordering of data over distribution channels.
13.3 Protocol between Connected Nodes
As from ERTS 5.7.2 the runtime system passes a distribution flag in the handshake stage that enables the use of a distribution header on all messages passed. Messages passed between nodes have in this case the following format:
| 4 | d | n | m |
| Length | DistributionHeader | ControlMessage | Message |
- Length
-
Equal to d + n + m.
- ControlMessage
-
A tuple passed using the external format of Erlang.
- Message
-
The message sent to another node using the '!' (in external format). Notice that Message is only passed in combination with a ControlMessage encoding a send ('!').
Notice that the version number is omitted from the terms that follow a distribution header.
Nodes with an ERTS version earlier than 5.7.2 does not pass the distribution flag that enables the distribution header. Messages passed between nodes have in this case the following format:
| 4 | 1 | n | m |
| Length | Type | ControlMessage | Message |
- Length
-
Equal to 1 + n + m.
- Type
-
Equal to 112 (pass through).
- ControlMessage
-
A tuple passed using the external format of Erlang.
- Message
-
The message sent to another node using the '!' (in external format). Notice that Message is only passed in combination with a ControlMessage encoding a send ('!').
The ControlMessage is a tuple, where the first element indicates which distributed operation it encodes:
- LINK
-
{1, FromPid, ToPid}
- SEND
-
{2, Unused, ToPid}
Followed by Message.
Unused is kept for backward compatibility.
- EXIT
-
{3, FromPid, ToPid, Reason}
- UNLINK
-
{4, FromPid, ToPid}
- NODE_LINK
-
{5}
- REG_SEND
-
{6, FromPid, Unused, ToName}
Followed by Message.
Unused is kept for backward compatibility.
- GROUP_LEADER
-
{7, FromPid, ToPid}
- EXIT2
-
{8, FromPid, ToPid, Reason}
13.4 New Ctrlmessages for distrvsn = 1 (Erlang/OTP R4)
- SEND_TT
-
{12, Unused, ToPid, TraceToken}
Followed by Message.
Unused is kept for backward compatibility.
- EXIT_TT
-
{13, FromPid, ToPid, TraceToken, Reason}
- REG_SEND_TT
-
{16, FromPid, Unused, ToName, TraceToken}
Followed by Message.
Unused is kept for backward compatibility.
- EXIT2_TT
-
{18, FromPid, ToPid, TraceToken, Reason}
13.5 New Ctrlmessages for distrvsn = 2
distrvsn 2 was never used.
13.6 New Ctrlmessages for distrvsn = 3 (Erlang/OTP R5C)
None, but the version number was increased anyway.
13.7 New Ctrlmessages for distrvsn = 4 (Erlang/OTP R6)
These are only recognized by Erlang nodes, not by hidden nodes.
- MONITOR_P
-
{19, FromPid, ToProc, Ref}, where FromPid = monitoring process and ToProc = monitored process pid or name (atom)
- DEMONITOR_P
-
{20, FromPid, ToProc, Ref}, where FromPid = monitoring process and ToProc = monitored process pid or name (atom)
We include FromPid just in case we want to trace this.
- MONITOR_P_EXIT
-
{21, FromProc, ToPid, Ref, Reason}, where FromProc = monitored process pid or name (atom), ToPid = monitoring process, and Reason = exit reason for the monitored process
13.8 New Ctrlmessages for Erlang/OTP 21
- SEND_SENDER
-
{22, FromPid, ToPid}
Followed by Message.
This control messages replace the SEND control message and will be sent when the distribution flag DFLAG_SEND_SENDER has been negotiated in the connection setup handshake.
NoteMessages encoded before the connection has been set up may still use the SEND control message. However, once a SEND_SENDER or SEND_SENDER_TT control message has been sent, no more SEND control messages will be sent in the same direction on the connection.
- SEND_SENDER_TT
-
{23, FromPid, ToPid, TraceToken}
Followed by Message.
This control messages replace the SEND_TT control message and will be sent when the distribution flag DFLAG_SEND_SENDER has been negotiated in the connection setup handshake.
NoteMessages encoded before the connection has been set up may still use the SEND_TT control message. However, once a SEND_SENDER or SEND_SENDER_TT control message has been sent, no more SEND_TT control messages will be sent in the same direction on the connection.

Review by Lars Lindahl
"Boiler Room" (2000)
Directed by Ben Younger Written by Ben Younger
Starring Giovanni Ribisi, Nia Long, Vin Diesel , Nicky Katt, Scott Caan, Jamie Kennedy, Ron Rifkin, and Ben Affleck.
While watching Boiler Room, I was constantly reminded of last year's masterpiece Fight Club. Both films consist of a predominately male cast. Both films follow young men as they illicitly fight the traditional system for their own desires. And both films are seen through the eyes of one narrator, who eventually realizes that these men have to be stopped. While Boiler Room writer/director Ben Younger does not get his point across as well as David Fincher does for Fight Club, he does contribute another impressive work to a series of films aiming to represent the new generation. A generation which has seen the internet prosper and where everyone wants to be a millionaire. Paying homage to Oliver Stone's 1987 classic Wall Street, Younger is almost modernizing the tale by using younger, hipper actors to play the greedy villains as opposed to the older, more experienced types. As is true in real life, younger minds are becoming richer and richer from their knowledge of more standard technology. Boiler Room dismisses the notion of ingenuity and shows that greed and desire for power come in all ages.
Another similarity with Fight Club is that both films are not action flicks. Some people are convinced that an all-male cast automatically means there must be gory violence, here is proof that this is not true. If you want to see an action movie starring Ben Affleck, go see Reindeer Games this weekend. If you want to see a smart, insightful film with excellent acting and a clever script, see Boiler Room.
Giovanni Ribisi gives an outstanding performance as the film's narrator, Seth. After dropping out of college and running a lucrative gambling center for college students in his apartment, Seth is offered a high paying job by a wealthy man (Nicky Katt). He agrees to take the job (in which you are guaranteed to become a millionaire within three years) of selling stock to well-off Americans from the mid-west over the telephone and begins to fit in quite well with his co-workers. Learning tricky techniques to deceive innocent people into buying shares of a good in production, Seth figures this is too good to be true. After stumbling into a room at the wrong time, he knows there is something no good about this company. At this point, Seth is left with the ultimate choice; continue with the American dream and make millions or tell the authorities that something fishy is going on.
Ribisi is believable as Seth especially when he shares scenes with Ron Rifkin, playing Seth's dad. The two have perfect chemistry as a troubled father and son trying to impress each other and simultaneously impress themselves. The transitions from anger to sympathy that these scenes contain are the standout segments of the entire film. The supporting cast of greedy co-workers is also flawless. Ben Affleck shines in a short but sweet performance as a recruiter for the company, Nicky Katt is fabulous as the ostensibly friendly boss who eventually becomes extremely jealous of Seth, and Vin Diesel gives his best performance of his career as the foil character of Nicky Katt. The energy of the cast as a whole makes Boiler Room well paced and never boring.
The only major error in the film is that nothing major happens. There is no big plot twist or climatic point to make the film more memorable. Due to the lack of a major event, Boiler Room never finds a suitable genre to fit into.  In having trouble to characterize the movie as a whole, Boiler Room is slightly confused at times. It doesn't seem to know which category to fit itself into. One satisfying concluding scene could have changed the whole film for the better. Otherwise, the movie is fun to watch thanks to its lively cast of young actors.
Grade: *** (out of four)
