What
is Bitcoin?
Bitcoin is a collection of
concepts and technologies that form the basis of a digital money ecosystem.
Units of currency called bitcoins are used to store and transmit value among participants
in the bitcoin network. Bitcoin users communicate with each other using the
bitcoin protocol primarily via the Internet, although other transport networks
can also be used. The bitcoin protocol stack, available as open source
software, can be run on a wide range of computing devices, including laptops
and smartphones, making the technology easily accessible.
Users can transfer bitcoin over
the network to do just about anything that can be done with conventional
currencies, such as buy and sell goods, send money to people or organizations,
or extend credit. Bitcoin technology includes features that are based on
encryption and digital signatures to ensure the security of the bitcoin
network. Bitcoins can be purchased, sold and exchanged for other currencies at
specialized currency exchanges. Bitcoin in a sense is the perfect form of money
for the Internet because it is fast, secure, and borderless.
Unlike traditional currencies,
bitcoins are entirely virtual. There are no physical coins or even digital
coins per se. The coins are implied in transactions which transfer value from
sender to recipient. Users of bitcoin own keys which allow them to prove
ownership of transactions in the bitcoin network, unlocking the value to spend
it and transfer it to a new recipient. Those keys are often stored in a digital
wallet on each user�s computer. Possession of the key that unlocks a
transaction is the only prerequisite to spending bitcoins, putting the control
entirely in the hands of each user.
Bitcoin is a fully-distributed,
peer-to-peer system. As such there is no �central� server or point of control.
Bitcoins are created through a process called �mining�, which involves looking
for a solution to a difficult problem. Any participant in the bitcoin network (i.e.,
any device running the full bitcoin protocol stack) may operate as a miner,
using their computer�s processing
power to attempt to find solutions to this problem. Every 10 minutes on
average, a new solution is found by someone who then is able to validate the
transactions of the past 10 minutes and is rewarded with brand new bitcoins.
Essentially, bitcoin mining de-centralizes the currency-issuance and clearing
functions of a central bank and replaces the need for any central bank with
this global competition. The bitcoin protocol includes built-in algorithms that
regulate the mining function across the network. The difficulty of the problem
that miners must solve is adjusted dynamically so that, on average, someone
finds a correct answer every 10 minutes regardless of how many miners (and
CPUs) are working on the problem at any moment. The protocol also halves the
rate at which new bitcoins are created every 4 years, and limits the total
number of bitcoins that will be created to a fixed total of 21 million coins.
The result is that the number of bitcoins in circulation closely follows an
easily predictable curve that reaches 21 million by the year 2140. Due to
bitcoin�s diminishing rate of issuance, over the long term, the bitcoin
currency is deflationary. Furthermore, bitcoin cannot be inflated by �printing�
new money above and beyond the expected issuance rate.
Behind the scenes, bitcoin is also
the name of the protocol, a network and a distributed computing innovation. The
bitcoin currency is really only the first application of this invention. As a
developer, I see bitcoin as akin to the Internet of money, a network for
propagating value and securing the ownership of digital assets via distributed
computation. There�s a lot more to bitcoin than first meets the eye.
In this chapter we�ll get started
by explaining some of the main concepts and terms, getting the necessary
software and using bitcoin for simple transactions. In following chapters we�ll
start unwrapping the layers of technology that make bitcoin possible and
examine the inner workings of the bitcoin network and protocol.
The emergence of viable digital money is closely linked to
developments in cryptography. This is not surprising when one considers the fundamental
challenges involved with using bits to represent value that can be exchanged
for goods and services. Two fundamental questions for anyone accepting digital
money are:
1. Can I trust the money is authentic and not counterfeit?
2. Can I be sure that no one else can claim that this money belongs
to them and not me? (aka the �double-spend� problem)
Issuers of paper money are constantly battling the counterfeiting
problem by using increasingly sophisticated papers and printing technology.
Physical money addresses the double-spend issue easily because the same paper
note cannot be in two places at once. Of course, conventional money is also
often stored and transmitted digitally. In this case the counterfeiting and
double-spend issues are handled by clearing all electronic transactions through
central authorities that have a global view of the currency in circulation. For
digital money, which cannot take advantage of esoteric inks or holographic
strips, cryptography provides the basis for trusting the legitimacy of a user�s
claim to value. Specifically, cryptographic digital signatures enable a user to
sign a digital asset or transaction proving the ownership of that asset. With
the appropriate architecture, digital signatures also can be used to address
the double-spend issue. When cryptography started becoming more broadly
available and understood in the late 1980s, many researchers began trying to
use cryptography to build digital currencies. These early digital currency
projects issued digital money, usually backed by a national currency or
precious metal such as gold.
While these earlier digital currencies worked, they were
centralized and as a result they were easy to attack by governments and
hackers. Early digital currencies used a central clearinghouse to settle all
transactions at regular intervals, just like a traditional banking system.
Unfortunately, in most cases these nascent digital currencies were targeted by
worried governments and eventually litigated out of existence. Some failed in
spectacular crashes when the parent company liquidated abruptly. To be robust
against intervention by antagonists, whether legitimate governments or criminal
elements, a decentralized digital currency was needed to avoid a single point
of attack. Bitcoin is such a system, completely de-centralized by design, and
free of any central authority or point of control that can be attacked or
corrupted.
Bitcoin represents the culmination of decades of research in
cryptography and distributed systems and includes four key innovations brought
together in a unique and powerful combination. Bitcoin consists of:
� A de-centralized peer-to-peer network (the bitcoin protocol);
� A public transaction ledger (the blockchain);
� A de-centralized mathematical and deterministic currency issuance (distributed
mining), and;
� A de-centralized transaction verification system (transaction
script).
Bitcoin was invented in 2008 by
Satoshi Nakamoto with the publication of a paper titled �Bitcoin: A
Peer-to-Peer Electronic Cash System�. Satoshi Nakamoto combined several prior
inventions such as b-money and HashCash to create a completely de-centralized
electronic cash system that does not rely on a central authority for currency
issuance or settlement and validation of transactions. The key innovation was
to use a distributed computation system (called a �Proof-Of-Work� algorithm) to
conduct a global �election� every 10 minutes, allowing the de-centralized
network to arrive at consensus about
History of Bitcoin
the state of transactions. This
elegantly solves the issue of double-spend where a single currency unit can be
spent twice. Previously, the double-spend problem was a weakness of digital
currency and was addressed by clearing all transactions through a central
clearinghouse.
The bitcoin network started in
2009, based on a reference implementation published by Nakamoto and since
revised by many other programmers. The distributed computation that provides
security and resilience for bitcoin has increased exponentially and now exceeds
that combined processing capacity of the world�s top super-computers. Bitcoin�s
total market value is estimated at between 5 and 10 billion US dollars,
depending on the dollar/bitcoin exchange rate. The largest transaction
processed so far by the network was $150 million US dollars, transmitted
instantly and processed without any fees.
Satoshi Nakamoto withdrew from the
public in April of 2011, leaving the responsibility of developing the code and
network to a thriving group of volunteers. The name Satoshi Nakamoto is an
alias and the identity of the person or people behind this invention is
currently unknown. However, neither Satoshi Nakamoto nor anyone else exerts
control over the bitcoin system, which operates based on fully transparent
mathematical principles. The invention itself is groundbreaking and has already
spawned new science in the fields of distributed computing, economics and
econometrics.
Satoshi Nakamoto�s invention is also a practical solution to a
previously unsolved problem in distributed computing, known as the Byzantine
Generals� Problem. Briefly, the problem consists of trying to agree on a course
of action by exchanging information over an unreliable and potentially
compromised network. Satoshi Nakamoto�s solution, which uses the concept of
Proof-of-Work to achieve consensus without a central trusted authority
represents a breakthrough in distributed computing science and has wide
applicability beyond currency. It can be used to achieve consensus on
decentralized networks for provably-fair elections, lotteries, asset
registries, digital notarization and more.
Bitcoin is a technology, but it
expresses money which is fundamentally a language for exchanging value between
people. Let�s look at the people who are using bitcoin and some of the most
common uses of the currency and protocol through their stories. We will re-use
these stories throughout the book to illustrate the real-life uses of digital
money and how they are made possible by the various technologies that are part
of bitcoin.
North American Low Value Retail
Alice lives in Northern
California�s Bay Area. She has heard about bitcoin from her techie friends and
wants to start using it. We will follow her story as she learns about bitcoin,
acquires some and then spends some of her bitcoin to buy a cup of coffee at
Bob�s Cafe in Palo Alto. This story will introduce us to the software, the
exchanges and basic transactions from the perspective of a retail consumer.
North American High Value Retail
Carol is an art gallery owner in
San Francisco. She sells expensive paintings for bitcoin. This story will
introduce the risks of a �51%� consensus attack for retailers of high-value
items.
Offshore Contract Services
Bob, the cafe owner in Palo Alto
is building a new website. He has contracted with an Indian web developer,
Gopesh, who lives in Bangalore, India. Gopesh has agreed to be paid in bitcoin.
This story will examine the use of bitcoin for outsourcing, contract services
and international wire transfers.
Charitable Donations
Eugenia is the director of a
children�s charity in the Philippines. Recently she has discovered bitcoin and
wants to use it to reach a whole new group of foreign and domestic donors to
fundraise for her charity. She�s also investigating ways to use bitcoin to
distribute funds quickly to areas of need. This story will show the use of
bitcoin for global fundraising across currencies and borders and the use of an
open ledger for transparency in charitable organizations.
Import/Export
Mohammed is an electronics
importer in Dubai. He�s trying to use bitcoin to buy electronics from the USA
and China for import into the U.A.E. to accelerate the process of payments for
imports. This story will show how bitcoin can be used for large
business-to-business international payments tied to physical goods.
Mining for Bitcoin
Jing is a computer engineering
student in Shanghai. He has built a �mining� rig to mine for bitcoins, using
his engineering skills to supplement his income. This story will examine the
�industrial� base of bitcoin, the specialized equipment used to secure the
bitcoin network and issue new currency.
Each of the stories above is based
on real people and real industries that are currently using bitcoin to create
new markets, new industries and innovative solutions to global economic issues.
Bitcoin Uses, Users and Their Stories
To join the bitcoin network and
start using the currency, all a user has to do is download an application or
use a web application. Since bitcoin is a standard, there are many
implementations of the bitcoin client software. There is also a �reference
implementation�, also known as the Satoshi Client, which is managed as an open
source project by a team of developers and is derived from the original
implementation written by Satoshi Nakamoto.
The three primary forms of bitcoin
clients are:
Full Client
A full client, or �full node� is a
client that stores the entire history of bitcoin transactions (every transaction
by every user, ever), manages the user�s wallets and can initiate transactions
directly on the bitcoin network. This is similar to a standalone email server,
in that it handles all aspects of the protocol without relying on any other
servers or third party services.
Light Client
A lightweight client stores the
user�s wallet but relies on third-party owned servers for access to the bitcoin
transactions and network. The light client does not store a full copy of all
transactions and therefore must trust the third party servers for transaction
validation. This is similar to a standalone email client that connects to a
mail server for access to a mailbox, in that it relies on a third party for
interactions with the network.
Web Client
Web-clients are accessed through a
web browser and store the user�s wallet on a server owned by a third party.
This is similar to webmail in that it relies entirely on a third party server.
Mobile clients for smartphones, such as those based on the Android
system, can either operate as full clients, light clients or web clients. Some
mobile clients are synchronized with a web or desktop client, providing a
multi-platform wallet across multiple devices but with a common source of
funds.
The choice of bitcoin client
depends on how much control the user wants over funds. A full client will offer
the highest level of control and independence for the user, but in turn puts
the burden of backups and security on the user. On the other end of the range
of choices, a web client is the easiest to set up and use, but the tradeoff
with a web client is that counterparty risk is introduced because security and
control is shared by the user and the owner of the web service. If a web-wallet
service is compromised, as many have
been, the users can lose all their
funds. Conversely, if a user has a full client without adequate backups, they
may lose their funds through a computer mishap.
For the purposes of this book, we
will be demonstrating the use of a variety of bitcoin clients, from the
reference implementation (the Satoshi client) to web-wallets. Some of the
examples will require the use of the reference client which exposes APIs to the
wallet, network and transaction services. If you are planning to explore the
programmatic interfaces into the bitcoin system, you will need the reference
client.
Quick
Start
Alice, who we introduced in �Bitcoin Uses, Users and Their Stories� on page 4, is not a technical user and only recently heard about bitcoin
from a friend. She starts her journey by visiting the official website
bitcoin.org, where she finds a broad selection of bitcoin clients. Following
the advice on the bitcoin.org site, she chooses the lightweight bitcoin client Multibit.
Alice follows a link from the
bitcoin.org site to download and install Multibit on her desktop. Multibit is
available for Windows, Mac OS and Linux desktops.
A bitcoin wallet must be protected
by a password or passphrase. There are many bad actors attempting to break weak
passwords, so take care to select one that cannot be easily broken. Use a
combination of upper and lower-case characters, numbers and symbols. Avoid
personal information such as birth-dates or names of sports teams. Avoid any
words commonly found in dictionaries, in any language. If you can, use a
password generator to create a completely random password that is at least 12
characters in length. Remember: bitcoin is money and can be instantly moved
anywhere in the world. If it is not well protected, it can be easily stolen.
Once Alice has downloaded and
installed the Multibit application, she runs it and is greeted by a �welcome�
screen:
Figure 1-1. The Multibit Bitcoin
Client - Welcome Screen
Multibit automatically creates a
wallet and a new bitcoin address for Alice, which Alice can see by clicking on
the �Request� tab:
Figure 1-2. Alice�s new bitcoin
address, in the �Request� tab of the Multibit client
The most important part of this
screen is Alice�s bitcoin address. Like an email address, Alice can share this address and anyone
can use it to send money directly to her new wallet. On the screen it appears
as a long string of letters and numbers: 1Cdid9KFAaatwczBwBttQcwXYCpvK8h7FK. Next to the wallet�s bitcoin address, there is a QR code, a form
of barcode that contains the same information in a format that can be easily
scanned by a smartphone�s camera. The QR code is the black and white square on
the right side of the window. Alice can copy the bitcoin address or the QR code
onto her clipboard by clicking on the copy button adjacent to each of them.
Clicking on the QR code itself will magnify it, so that it can be easily
scanned by a smartphone camera. Alice can also print the QR code as a way to
easily give her address to others without them having to type the long string
of letters and numbers.
Bitcoin addresses start with the
digit �1� or �3�. Like email addresses, they can be shared with other bitcoin
users who can use them to send bitcoin directly to your wallet. Unlike email
addresses, you can create new addresses as often as you like, all of which will
direct funds to your wallet. A wallet is simply a collection of addresses and
the keys that unlock the funds within. There is practically no limit to the
number of addresses a user can create.
Alice is now ready to start using
her new bitcoin wallet.
It is not possible to buy bitcoins
at a bank or foreign exchange kiosks at this time. As of
2014, it is still quite difficult
to acquire bitcoins in most countries. There are a number of specialized
currency exchanges where you can buy and sell bitcoin in exchange for a local
currency. These operate as web-based currency markets and include:
� Bitstamp (bitstamp.net), a European currency market that supports
several currencies including euros (EUR) and US dollars (USD) via wire transfer
� Coinbase (coinbase.com), a US-based bitcoin wallet and platform
where merchants and consumers can transact in bitcoin. Coinbase makes it easy
to buy and sell bitcoin, allowing users to connect to US checking accounts via
the ACH system.
Crypto-currency exchanges such as
these operate at the intersection of national currencies and crypto-currencies.
As such, they are subject to national and international regulations and are
often specific to a single country or economic area and specialize in the
national currencies of that area. Your choice of currency exchange will be
specific to the national currency you use and limited to the exchanges that
operate within the legal jurisdiction of your country. Similar to opening a
bank account, it takes several days or weeks to set up the necessary accounts
with the above services because they require various forms of identification to
comply with KYC (Know Your Customer) and AML (Anti-Money Laundering) banking
regulations. Once you have an account on a bitcoin exchange, you can then buy
or sell bitcoins quickly just as you could with foreign currency with a
brokerage account.
A more
complete list can be found at http://bitcoincharts.com/markets/, a site that offers price quotes and
other market data across many dozens of currency exchanges. There are three
other methods for getting bitcoins as a new user:
� Find a friend who has bitcoins and buy some from them directly.
Many bitcoin users started this way.
� Use a classified service like localbitcoins.com to find a seller
in your area to buy bitcoins for cash in an in-person transaction.
� Sell a product or service for bitcoin. If you�re a programmer,
sell your programming skills. If you have an online store, see (to come) to
sell in bitcoin.
� Use a bitcoin ATM in your city. A map of bitcoin ATMs can be found
at http:// www.coindesk.com/bitcoin-atm-map/
Alice was introduced to bitcoin by
a friend and so she has an easy way of getting her first bitcoin while she
waits for her account on a California currency market to be verified and activated.
Alice has created her bitcoin
wallet and she is now ready to receive funds. Her wallet application randomly
generated a private key (described in more detail in �Private Keys� on page 63) together with its corresponding bitcoin address. At this point,
her bitcoin address is not known to the bitcoin network or �registered� with
any part of the bitcoin system. Her bitcoin address is simply a number that
corresponds to a key that she can use to control access to the funds. There is
no account or association between that address and an account. Until the moment
this address is referenced as the recipient of value in a transaction posted on
the bitcoin ledger (the blockchain), it is simply part of the vast number of
possible addresses that are �valid� in bitcoin. Once it has been associated
with a transaction, it becomes part of the known addresses in the network and
Alice can check its balance on the public ledger.
Alice meets her friend Joe who
introduced her to bitcoin at a local restaurant so they can exchange some US
dollars and put some bitcoins into her account. She has brought a printout of
her address and the QR code as displayed in her bitcoin wallet. There is
nothing sensitive, from a security perspective, about the bitcoin address. It
can be posted anywhere without risking the security of her account.
Alice wants to convert just $10 US
dollars into bitcoin, so as not to risk too much money on this new technology.
She gives Joe a $10 bill and the printout of her address so that Joe can send
her the equivalent amount of bitcoin.
Next, Joe has to figure out the
exchange rate so that he can give the correct amount of bitcoin to Alice. There
are hundreds of applications and web sites that can provide the current market
rate, here are some of the most popular:
� bitcoincharts.com, a market data listing service that shows the
market rate of bitcoin across many exchanges around the globe, denominated in
different local currencies
� bitcoinaverage.com, a site that provides a simple view of the
volume-weightedaverage for each currency
� ZeroBlock, a free Android and iOS application that can display a
bitcoin price from different exchanges
� bitcoinwisdom.com, another market data listing service
Figure 1-3. ZeroBlock - A bitcoin
market-rate application for Android and iOS
Using one of the applications or
websites above, Joe determines the price of bitcoin to be approximately $100 US
dollars per bitcoin. At that rate he should give Alice 0.10 bitcoin, also known
as 100 milliBits, in return for the $10 US dollars she gave him.
Once Joe has established a fair
exchange price, he opens his mobile wallet application and selects to �send�
bitcoin. He is presented with a screen requesting two inputs:
� The destination bitcoin address for the transaction
� The amount of bitcoin to send
Figure 1-4. Bitcoin mobile wallet
- Send bitcoin screen
In the input field for the bitcoin
address, there is a small icon that looks like a QR code. This allows Joe to
scan the barcode with his smartphone camera so that he doesn�t have to type in
Alice�s bitcoin address (1Cdid9KFAaatwczBwBttQcwXYCpvK8h7FK), which is quite long and difficult to type. Joe taps on the QR
code icon and activates the smartphone camera, scanning the QR code from
Alice�s printed wallet that she brought with her. The mobile wallet application
fills in the bitcoin address and Joe can check that it scanned correctly by
comparing a few digits from the address with the address printed by Alice.
Joe then enters the bitcoin value
for the transaction, 0.10 bitcoin. He carefully checks to make sure he has
entered the correct amount, as he is about to transmit money and any mistake
could be costly. Finally, he presses �Send� to transmit the transaction. Joe�s
mobile bitcoin wallet constructs a transaction that assigns 0.10 bitcoin to the
address provided by Alice, sourcing the funds from Joe�s wallet and signing the
transaction with Joe�s private keys. This tells the bitcoin network that Joe
has authorized a transfer of value from one of his addresses to Alice�s new
address. As the transaction is transmitted via the peer-to-peer protocol, it
quickly propagates across the bitcoin network. In less than a second, most of
the well-connected nodes in the network receive the transaction and see Alice�s
address for the first time.
If Alice has a smartphone or
laptop with her, she will also be able to see the transaction. The bitcoin
ledger - a constantly growing file that records every bitcoin transaction that
has ever occurred - is public, meaning that all she has to do is look up her
own address and see if any funds have been sent to it. She can do this quite
easily at the blockchain.info website by entering her address in the search
box. The website will show her a page (https://blockchain.info/address/1Cdid9KFAaatwczBwBttQcwXYCpvK8h7FK)
listing all the transactions to and from that address. If Alice is watching
that page, it will update to show a new transaction transferring 0.10 bitcoin
to her balance soon after Joe hits �Send�.
At first, Alice�s address will show the transaction from Joe as
�Unconfirmed�. This means that the transaction has been propagated to the
network but has not yet been included in the bitcoin transaction ledger, known
as the blockchain. To be included, the transaction must be �picked up� by a
miner and included in a block of transactions. Once a new block is created, in
approximately 10 minutes, the transactions within the block will be accepted as
�confirmed� by the network and can be spent. The transaction is seen by all
instantly, but it is only �trusted� by all when it is included in a newly mined
block.
Alice is now the proud owner of 0.10 bitcoin which she can spend.
In the next chapter we will look at her first purchase with bitcoin and examine
the underlying transaction and propagation technologies in more detail.

Here is a semi-practical example demonstrating the usefulness of a DocFile. A very common requirement for an application that uses a TreeView, is to save the TreeView to disk.
Form many people the TreeView's SaveToFile method is just not good enough as it only saves the tree structure. All TTreeNode information like images, data etc is lost.
To keep the example short I've used my TDocFile classes to simplify things.
Saving to a DocFile
procedure Save_CallBack( Node : TTreeNode; pData : pointer ); var stor : TDocFileStorage; subStor : TDocFileStorage; strmImages : TDocFileStream; begin {End of recursion (base case)} if( (Node = nil) or (pData = nil) ) then Exit; stor := TDocFileStorage(pData); {Create a storage for this node NB Remember the limits on a storage element's name, (31 chars max etc...)} subStor := stor.CreateStorage( Node.Text, MY_STGM_CREATE ); {Was storage created} if( subStor = nil ) then begin ShowMessage( 'Error creating sub-storage' ); Exit; end; {Open the stream for saving the image info to} strmImages := subStor.CreateStream( 'Images', MY_STGM_CREATE ); {Images stream created?} if( strmImages = nil ) then begin ShowMessage( 'Error Creating stream' ) end else begin {Save image and selected index} strmImages.WriteString( IntToStr( Node.ImageIndex ) + #13#10 + IntToStr( Node.SelectedIndex ) ); end; {Save all children} if( Node.GetFirstChild <> nil ) then Save_CallBack( Node.GetFirstChild, subStor ); {Save all siblings} if( Node.GetNextSibling <> nil ) then Save_CallBack( Node.GetNextSibling, stor ); strmImages.Free; subStor.Free; end; procedure TForm1.but_SaveClick(Sender: TObject); var storFile : TDocFileStorage; begin {Create the file} storFile := CreateDocFile( ExtractFilePath( Application.ExeName ) + '\z.ole', MY_STGM_CREATE ); if( storFile = nil ) then begin ShowMessage( 'Cant create file' ); Exit; end; {Start saving} Save_CallBack( tv_eg5.Items[ 0 ], storFile ); {Done} storFile.Free; end;
When the save button is clicked the following occurs
The Save_CallBack function works as follows
Loading the data back from the DocFile is slightly (only just) more complex than saving it.
procedure Load_CallBack( Node : TTreeNode; pData : pointer ); var stor : TDocFileStorage; substor : TDocFileStorage; strmImages : TDocFileStream; begin stor := TDocFileStorage(pData); {Open the storage for this element} substor := stor.OpenStorage( Node.Text, MY_STGM_OPEN ); {Storage opened?} if( substor = nil ) then begin ShowMessage( 'Cant open storage ' + Node.Text ); Exit; end; {Open the images stream} strmImages := substor.OpenStream( 'Images', MY_STGM_OPEN ); {Stream open?} if( strmImages <> nil ) then begin with TStringList.Create do begin {Load the stream's data into a TString List} LoadFromStream( strmImages ); if( Count > 0 ) then begin {Get the saved image index} Node.ImageIndex := StrToInt( Strings[ 0 ] ); if( Count > 1 ) then {Get the saved selected index} Node.SelectedIndex := StrToInt( Strings[ 1 ] ); end; Free; end; {Close the stream} strmImages.Free; end; {Enum all sub-elements} substor.EnumElements( Form1.LoadName_callback, substor ); {Done with storage} substor.Free; end; function TForm1.LoadName_callback( sElementName : WideString; dwType : DWORD; pData : pointer ) : boolean; var Node : TTreeNode; OldNode : TTreeNode; begin {Continue enum} Result := true; {Only interested in storages} if( dwType <> STGTY_STORAGE ) then Exit; {Save the node that is currently selected} OldNode := tv_eg5.Selected; {Add a new node for this element} Node := tv_eg5.Items.AddChild( tv_eg5.Selected, sElementName ); {Select new node} Node.Selected := true; {Load data and all sub-elements} Load_CallBack( Node, pData ); {Select old node again} if( OldNode <> nil ) then OldNode.Selected := true; end; procedure TForm1.but_LoadClick(Sender: TObject); var storFile : TDocFileStorage; begin {Open the file} storFile := OpenDocFile( ExtractFilePath( Application.ExeName ) + '\z.ole', MY_STGM_OPEN ); {Was the DocFile opened} if( storFile = nil ) then begin ShowMessage( 'Cant open file' ); Exit; end; {Remove all tree nodes} tv_eg5.Items.Clear; {Enum all root level elements in the storage file} storFile.EnumElements( LoadName_callback, storFile ); {Done} storFile.Free; end;
As you can see there are three functions involved here, the loading (and recursion) takes place beteen LoadName_callback and Load_CallBack.

The reason for that is that saving the TTreeNode's data is very similar to
saving the image info to the stream. Natrally the exact method will be
differant depending on what type of data TTreeNode.Data represents.

Item: SCP-ES-002
Object Class: Keter
Special Containment Procedures: All copies of SCP-ES-002 must be stored in a 5m x 5m x 5m chamber, surrounded in turn by a vacuum-sealed vault. The entrance to the SCP-ES-002 chamber is controlled with a lead-lined lock to ensure absolute sound isolation, followed by two layers of specialized acoustic insulators for the SCP-ES-002 frequency range.
In order to preserve SCP-ES-002, twenty (20) minutes of carefully selected music will be issued for this purpose, whose tempo is not greater than walking (max 108 BPM) and no more than 60 dB , every six (6) hours, through an autonomous peripheral system, programmed for that purpose. In addition, its activity will be recorded through two (2) echolocation systems connected wirelessly to the Acoustic Imaging Laboratory of Site-127, both operating with tritium beta-volt batteries, with an approximate duration of twenty (20) years. In case of failure in the electronic components of the camera, maintenance technicians must enter through the lock, equipped with insulating helmets, and must not remain more than one (1) hour inside.
In case of containment gaps, an alert will be issued to the entire Site-127 and will be deployed to the Movile Task Force 002-D ("Silents Grants"), in charge of executing the Stille-K8 Protocol, which consists of neutralize any copy of SCP-ES-002 using sonic weaponry adjusted to the frequencies captured from each copy. All personnel affected by SCP-ES-002 must be taken to an anti-002 anechoic chamber in order to prevent its spread.
Comprehensive searches should be carried out in all areas that show the effect of [REDACTED] abroad (See Addendum 002-4), neutralizing all copies of SCP-ES-002. All civilians affected by SCP-ES-002 must undergo the Procedure Strepitus-Umbra as soon as possible.
Description: SCP-ES-002 it is a life form observed as merely acoustic. It has a moderate level of consciousness, and has been tentatively classified as Rivulis tremulae. SCP-ES-002 is mainly composed of waves that oscillate in frequencies between 14 and 18 kHz, which can be picked up by any organism provided with ears capable of listening in this range, or by electronic equipment. Any action performed by SCP-ES-002 will generate a sharp sawtooth beep, usually during its movement. SCP-ES-002 seems to exist as an isolated sound wave, presenting several of the physical characteristics of common acoustic waves.
SCP-ES-002 is able to "feed" when it is exposed to other lower frequency sound waves, having a certain predilection for polyphonic waves. SCP-ES-002 seems to be more appropriately nurtured when exposed to slow or ambient music, and exposure to loud music is not recommended (see Addendum 002-2). Sometimes, it is possible to hear SCP-ES-002 "excrete", perceived as "bits" of sound completely atonal. When it is fed, the sound seems to diminish its loudness, making it barely audible.
During its movements, SCP-ES-002 emits a succession of pulses between 14 and 18 kHz, whose loudness will largely depend on the amount of sound it has "consumed" previously. Echolocation scanners show that SCP-ES-002 is capable of moving in any direction within three-dimensional space, and always at a constant speed, measured at 1.2 m/s in a homogeneous air environment (78.7% N, 20.2% O, 1.1% H). The most particular feature of SCP-ES-002 is that it is capable of using any element that allows the propagation of waves, being able to cross solid materials at a higher speed, translocalised using input/output peripherals, and even use sound amplification devices in order to to move faster. The effects of reverberation have also shown a high efficiency in the scope of SCP-ES-002.
Addendum 002-1: SCP-ES-002 has a rather unusual behavior when heard by organisms that have a functional auditory system and able to capture frequencies up to 18 kHz, making it easier to identify in human subjects between 0 and 15 years old. When one of the pulses is heard, SCP-ES-002 will immediately move towards the ear of the organism (referred to as "host"), initiating the first phase of infestation. The mechanism by which SCP-ES-002 can identify what has been heard is still a matter of investigation.
SCP-ES-002 It will begin to move inside the body, starting with the cochlear tissue, and then going through the organs and systems of the body, without leaving the hypodermic layer of the skin, or through natural or artificial orifices. The affected human subjects indicate that at this stage of the infestation they usually hear a loud and deafening beep, which usually interferes with other audible sounds. After approximately twenty-four (24) hours, this sound ceases and SCP-ES-002 begins the second phase of infestation. The criteria of SCP-ES-002 to choose its host are unknown, not being associated with the distance or auditory capacity of the subject. Although the host is usually unique in each exposure, there have been cases where several subjects have been affected by a single copy of SCP-ES-002 with a moderate probability. See Appendix 002-3 for more information.
Once inside the organism, SCP-ES-002 continues to move within the body, but gradually decreasing its frequency, which has been defined experimentally by an almost logarithmic functional relationship according to specialized medical equipment. Next, the symptoms of the SCP-ES-002 infestation in humans are shown (the frequency of the table is that received by specialized audio equipment, the actual frequency issued by SCP-ES-002 is impossible to determine until now):
| Hours | Frequency Captured | Symptom |
|---|---|---|
| 1-5 | ~7200 Hz | Decrease to the cessation of the beep heard during the first phase of the SCP-ES-002 infestation. The subject begins to feel a slight disorientation and dizziness. Occasionally, there have been cases of loss of concentration and spasms. |
| 6-11 | ~2800 Hz | Mild increase in blood pressure, accompanied by persistent headaches, loss of balance and decreased control of the extremities. Vomiting has been reported at this stage. |
| 12-18 | ~840 Hz | Vomiting generalized, as well as a greater increase in pressure. Subjects are unable to walk short distances without tripping or falling, in addition to hearing disturbances. In one of every five cases a certain visual blur has been reported. |
| 19-36 | ~210 Hz | General spasms in the body, difficulty breathing and mild bleeding. In this phase it is normal to observe a number of symptoms, such as cold sweating, chills, intrapsychic hallucinations, expectorations, fractures in long bones and, in specific cases, a total lack of control of the intestinal activity, generating completely abnormal excretion patterns. |
| 37-108 | ~40 Hz | Generalized hemorrhages through all orifices of the body, often accompanied by bloody sputum, violent spasms and increased aggressiveness. In 86% of the affected subjects there are cases of conscious xenoglossia, usually associated with Bantu languages, and in two cases, tonal languages. This is the most dangerous phase of the infection of SCP-ES-002. |
| 109+ | ~6 Hz | From this moment, and in case the host can not be intervened, the xenoglossy will stop, and begin a process of muscular contractions that will increase exponentially in frequency. Death is usually associated with massive capillary tears, impaired blood flow and heart muscle overload, which can burst violently after three (3) hours after this phase. Autopsies have determined that at least 90% of the blood vessels have been torn or broken as a result of the action of SCP-ES-002. |
During xenoglossy, the guests of SCP-ES-002 will speak continuously, generally chaining relatively coherent words, with an almost exact pronunciation. Their vocal cords seem to stretch and contract abnormally, and they can emit beeps between 14 and 18 kHz at random times. When this happens, new copies of SCP-ES-002 are emerging from the host body, and can infect any organism that can perceive them. The reproduction method used by SCP-ES-002 during this stage is unknown; the analyzes have yielded little clarifying results.
Addendum 002-2: During a containment breach on October 25, 200█, several copies of SCP-ES-002 were scattered through Site-127 through the copper pipes, generating an audible metallic echo to several meters away. Upon leaving, one of them was heard by Researcher T██████, who also listened to music at 210 BPM on a portable audio playback device. SCP-ES-002 reacted erratically to this acoustic impulse and upon entering T oído's ear caused [REDACTED], immediately initiating the xenoglossia phase.
For the next ten (10) minutes, T██████ shouted painfully in a language similar to xhosa, while emitting three (3) pulses of 15.4 kHz per second. After four (4) minutes, several of his important arteries exploded, aggravating the hemorrhage, later [DATA EXPUNGED] several minutes after he died. In the area, three hundred and sixty-two (362) copies of SCP-ES-002 were found before initiating the Stille-K8 Protocol by the Movil Task Force 002-D, which managed to neutralize the specimens, with six (6 ) low.
Addendum 002-3: In an experiment scheduled on July 16, 201█ in order to study the physical properties of SCP-ES-002, one specimen was deposited in a soundproof chamber with integrated echolocation systems, and three subjects of test, separated by an anti-noise wall. It was conducted to SCP-ES-002 through a sound amplification system connected to a 5.1-channel Home Theater system. The pulse emitted by SCP-ES-002 reached 104 dB, causing two of the test subjects to become infected in unison. The third subject was affected after fifteen (15) minutes, although no pulse between 14 and 18 kHz was detected by the echolocation team.
The Protocol Stille-K8 was not enough to prevent the proliferation of copies of SCP-ES-002, who eventually broke the containment. Affected subjects were sent to anti-002 anechoic chambers to neutralize the threat, showing the psychological effects of acoustic isolation at forty (40) minutes of exposure. Only one of the subjects finished the live procedure, and is now under medical observation due to the sequelae.
Addendum 002-4: The copies of SCP-ES-002 still in the wild have been constantly sought after by the 002-D Team. It is estimated that there should still be about fifty (50), with six (6) successful neutralizations to date. The studies affirm that it is possible to discern the proximity of SCP-ES-002 in a certain area: when SCP-ES-002 moves above 3000 masl, it is capable of [REDACTED] itself, considerably increasing its speed, as well as its infectivity On land, this acoustic effect is perceived as a strong low frequency sound, similar to that emitted by a trumpet or similar wind instrument.

She also complained to one of her partner’s senior managers to say her ex-boyfriend had taken the images himself, Plymouth Crown Court heard.
This is one of very few cases brought under new revenge porn legislation, and one of the first where the perpetrator was a woman.
Doyle, of Plympton, Devon, pleaded guilty to two counts of disclosing private sexual photographs without consent with the intention of causing distress on June 8 and June 10.
The court heard how the defendant broke up with her partner, with whom she lived, in June last year.
Advertisement Advertisement
That same month Doyle contacted the victims daughter on Facebook, posing as a man using a fake profile.
To her horror she opened the message and saw one picture of her father’s face and another of his genitalia.
She forwarded it to her dad who confirmed that the photos were taken while he was in a relationship.
Judge James Townsend said: ‘It is particularly unpleasant after you involved a member of the victim’s family.’
The Crown Prosecution Service’s Nick Lewin said told the court how Doyle emailed the same pictures to her partner’s senior manager at work.
Acting as if she was an aggrieved customer, she said: ‘I am not happy with your staff. One of them sent these to my wife.’
Mr Lewin added: ‘I am glad to say that the company kept things under wraps and the only other people who know are that manager and the victim’s direct line manager.’
The court heard how the victim has since kept in touch with Doyle, who has ‘expressed a high level of remorse’.
Michael Green, defending, said drinking alcohol ‘seemed to be the build-up to this level of offending’.
Advertisement Advertisement
Doyle, who has no previous convictions, was handed a 12 month community order and a two month home curfew.
She was also told to pay an £85 victim surcharge and must undertake rehabilitation activity.
The judge declined to pass a restraining order to keep Doyle away from the victim.
It became a specific criminal offence to disclose private sexual photographs and films with intent to cause distress in April 2015.
But the number of prosecutions and convictions resulting from the new law are still low.
A support service for victims said the low numbers were ‘no surprise’ as victims often fear going through the legal process would be too traumatic.
Local news site Plymouth Live succeeded in removing a court order which effectively prevented media reporting Doyle’s identity.

Maharashtra googly: Sharad Pawar says Ajit's rabbit out of the hat not NCP decision
Other Nationalist Congress Party leaders -- Chhagan Bhujbal, Nawab Malik, Jayant Patil and Jitendra Awahad -- said they had no idea of what was to come. Praful Patel said Sharad Pawar had nothing to do with it.
HIGHLIGHTS
- NCP leaders in complete shock after stunning twist
- NCP not behind Ajit's defection: Sharad Pawar
- Sharad Pawar had nothing to do with it: Praful Patel
Sharad Pawar says his Nationalist Congress Party (NCP) had no hand in his nephew Ajit's astounding decision to join a BJP-led government.
Ajit Pawar himself said he reached the decision on his own.
Other NCP leaders -- Chhagan Bhujbal, Nawab Malik, Jayant Patil and Jitendra Awahad -- said they had no idea of what was to come. Praful Patel said Sharad Pawar had nothing to do with it.
Indians watched open-mouthed on Saturday as their TV screens showed Devendra Fadnavis of the BJP and Ajit Pawar taking oath as Maharashtra's chief minister and deputy chief minister, respectively.
That image -- which appears to have left the political establishment just as shellshocked -- came very much against the run of play: for days now, the NCP, the Congress and the Shiv Sena have been working on a prospective alliance, irrespective of their differing ideologies.
As recently as Friday evening, Sharad Pawar said the new alliance wanted Shiv Sena leader Uddhav Thackeray to be its chief minister.
Well, it looks like the Sena can forget about that for now.

This Week in Rust
Hello and welcome to another issue of This Week in Rust! Rust is a systems language pursuing the trifecta: safe, concurrent, and fast. This is a weekly summary of its progress and community. Want something mentioned? Send me an email!
This week brings a bunch of optimizations, cleanups, and the std::comm
rewrite. The pkgid
attribute has also seen some changes.
This week also brings a bunch of tiny bugfixes, many of which I do not mention
below. Out of the 52 PRs this week, I only mention 16. The decision to include
a PR or not is fairly arbitrary, but I try to maintain a “significance
barrier” so that the list is not huge and hard to read (and also to save me
work!). Examples of things which I will stop including mentions of are test
fixes, minor documentation changes, build infrastructure fixes, and any
cleanup to the compiler that doesn’t result in a relatively significant
speedup or memory usage decrease. I don’t do this out of malice, but out of
laziness and convenience. <3
What’s cooking on master?
52 PRs were merged this week.
Breaking Changes
std::comm
has been rewritten. In short, useChan::new
andSharedChan::new
to construct a Port/Chan pair. We’re in the ballpark of Go’s performance, which is exciting. Read the PR for more details.- Some more
std::vec::raw
cleanup has turned some free functions into methods..as_mut_buf
and friends have also been removed, replaced by using.as_ptr
,.as_mut_ptr
, and.len
. extra::ebml
has been partially<EMAIL_ADDRESS>A ton of useless traits,
ToOption
etc, have been removed. - A nasty bug where having an
impl
for a type forced it to be public has been fixed. Some types which were previously accessible may not be anymore, due to this. - The
pkgid
crate attribute has been renamed tocrate_id
. extra::sort
has been removed, and there is now asort
method on mutable slices (&mut [T]
).
Other Changes
- The
remove
andinsert
methods on vectors have had some unsafe code added to make them 3x faster. - The
sum
method onextra::stat::Stat
has been made more accurate. - debuginfo for by-value
self
has been fixed. return
is now allowed in closures for early return.crate_id
(thenpkgid
) now supports specifying the crate name.#foo:1.0
as the fragment will make the crate namefoo
, for examplegl
ingithub.com/bjz/gl-rs#gl:1.0
.- A
Pod
kind has been added for types where a memcpy is a logical copy. This behaves very similarly to the oldCopy
kind. - Stability attributes (
#[deprecated]
,#[experimental]
, etc) are now checked for method calls. - Metadata reading has been made 4x faster.
- msys terminals are now
supported by

Meeting
The weekly
meeting
discusses some pull requests, pkgid
, renaming extern mod
, the stdlib

In this week’s meeting, we discussed using the Critic review tool from Opera with github. We are currently experimenting it, with jgraham’s support. Jack also discussed his ongoing Rust upgrade which, as always, has uncovered several interesting Rust compiler bugs.
We also sketched out our current planning roadmap, along with a cheat sheet of some of the research topics we’re also investigating.
Announcements, etc
- The SF meetup happened. It was recorded and is available on Air Mozilla. The video is well worth watching.
- A broad vision for the Rust docs stack.
- Two bugs in the borrow checker every Rust developer should know about.
- Building Rust Code – Using Make Part 2.
- Video: 2D portaling demo in Rust and rust-sdl2.
- What do you want in a Rust book?.
- An etched copper Rust logo.
- Ohcount Rust support has been merged, so hopefully ohloh will have more accurate information for Rust projects soon.

I have a feeling you get a bunch of these, and I'm just hoping you see mine. Please know that I'm not demanding anything, this is just a suggestion that I feel has potential. I will be promoting your add on whether you implement this idea or not.
You and I both know the amount of cheaters as well as poorly run servers on Battlefield 3 is unacceptable and we just want to avoid them, but coming up with a list on your own takes a while and even though you can share it with others, it may not be enough. You still have to play in the bad servers to know for yourself. But what if there was a better way?
ACTUAL IDEA:
One person, maybe a mod from /r/battlefield3 (Reddit) can host their own online list of blacklisted servers and Players. You, as a player, could then punch in the link to that(those) blacklist(s) into the add on and it would connect (if it is available of course) and then take action based on those.
HOST PERSPECTIVE:
Simple GUI. Lets you pick the port number(for port forwarding and easier managing), punch in the unique ID or URL of the server or player profile (I am unaware of how battlelog tracks players or servers but there has to be some kind of unique key), you can then set the level of confirmed or unconfirmed(this will come up later[see USER PERSPECTIVE]). Obviously you will be able to delete servers or players from the list (in case of mistakes or a server goes down or something like that).
USER PERSPECTIVE:
Just a button on their browser. When click a menu pops out. The menu allows you to enter the link to the global blacklist for either players or servers or both and as many as you like. The menu also lets you choose the level of confidence. If a user or server is unconfirmed of cheating or poor management or anything, you can set it to "Unconfirmed" if you don't want to take that chance. Otherwise just set it to "Confirmed". Servers that show up in the server browser will have a background of Red to show an offense according to the addon or it could be removed from the list entirely. If it is not removed the player can still choose to join.
That's my idea. I hope this goes through and you see it. You put in a lot of work for this the way it is already and I would hate to burden you, but so far you are the only one with an add on like this that I've seen.
See you on the Battlefield!

Thanks for the idea. I think the possibilities of the radars not yet been fully exploited.
Any kind of a "better" way to share blacklist is on my plan.
I couldnt say at the moment what, when and how it comes , but it should come :-)
So keep noticed for updates.

Ok, there is not any more on the plan to integrate any global feature for radars.
I discussed it with many people and we came to the conclusion it that it is good without global lists, integrated in bblog.
Sorry.


_Six_Ways_to_Sunday_ (R) no stars (out of ****)
What is it with independent films with days of the week in their title? Last fall brought the awful _Thursday_, a pointless, plotless, blood-soaked exercise in nihilism. I thought it couldn't possibly get any worse than that detestable film, here comes _Six_Ways_to_Sunday_, which would more aptly be called _97_Minutes_to_Nowhere_.
_Six_Ways_ exemplifies, all too painfully, the traditional criticisms of independent film: pretentiousness, self-indulgent artiness, graphic violence, a would-be "hip" sense of humor, a touch of "taboo" subject matter. The flat-out awfulness shouldn't be a surprise once one discovers what director/co-scripter (with Marc Gerald) Adam Bernstein's only other credit is: arguably the worst big screen _Saturday_Night_Live_ of all time, _It's_Pat_. _Six_Ways_ follows Ohio teen Harry Odum (Norman Reedus), whose progress up the mafia ranks and budding romance with a mafia maid (Elina Lowensohn) causes some strain with his beloved, overprotective--to say the very least--mother (Deborah Harry).
As with any film, _Six_Ways_'s effectiveness--or, rather, lack thereof--lies in the execution, and while the basic story (loosely based on Charles Perry's novel _Portrait_of_a_Young_Man_Drowning_) may not sound so bad, it's everything else that makes the film as unwatchable as it is. The dialogue is often laughable in the wrong way; the direction a study in how _not_ to make a film (all flashy cuts and "surreal" visual narrative devices; jarringly abrupt shifts in tone); and the acting is even worse. Reedus is a former model for Prada, and his sub-amateurish performance shows it; Harry and Lowensohn duke it out for worst performance when their characters square off over Harry's affections. The only person, in front of or behind the camera, who makes any kind of positive impression is Adrien Brody, who plays Harry's wannabe gangsta best friend. That it is also one of the lesser performances I've seen Brody give says a lot about just how insufferable this worst-of-'99 shoo-in is. (opens March 5)

Process Heaps ELI5¶
Everything in Erlang is a Term.
A heap of the process is an array of Terms. A stack is another array of Terms. Stack is located inside the heap. Registers — are array of Terms too! Things on the heap are mostly arrays of Terms, but tagged with header tag (see Data Types Memory Layout).
Heap Carriers¶
Allocation in Erlang happens inside so called “carriers”. They look like “zone memory”, used by games — big chunks of system heap pre-allocated beforehand. Inside carriers the real allocation is happening. For simplicity you can imagine simple malloc/realloc, that’s how its done.
This complication is done to fight memory fragmentation and is not important
for the understanding.
You can see erts/emulator/beam/erl_*alloc.c
(many those files, one per
strategy of allocation). Emulator has command line flags, which control
allocation strategies (see http://erlang.org/doc/man/erts_alloc.html flags
section).
Allocating Inside Heap¶
When a process needs some memory, its heap_top
is incremented and memory
under it is ready to use. Some activities may want to allocate on other
process’ heaps, for example sending a message will perform a copy to the
receiving process.
No bookkeeping is happening inside a process heap. There is no tracking which word belongs where, but it is possible to know what is stored in each memory cell by looking at the tag bits.
Garbage Collection¶
Garbage collector traces known live values from registers and stack and saves them, then drops everything else.
When a heap comes to its capacity threshold (something like 75%), the process triggers garbage collection. A new bigger heap may be allocated. Scanning generational garbage collection algorithm runs on the heap. The algorithm takes the “roots” and moves them to the new heap. Then it scans the remaining parts of source heap and extracts more values, referred by the roots. After the scanning, source heap contains only dead values and algorithm drops it.
“Scanning” means, that garbage collector follows the data
roots from the start to the end, parsing everything it meets.
“Generational” means, that algorithm splits data into young and old generation,
assuming that data often dies young, and old data is less likely to be freed.
Also the algorithm remembers the old position (mature
), where the previous
scanning has finished.
Any data below it is guaranteed to have not updated since the last scan.
This trick reduces amount of scanning and speeds up the algorithm.
In reality the picture is a bit more complicated. There can be one or two heaps with different placement logic applied to them.
Having garbage collector run per process heap allows Erlang to keep collection latency low. Also it doesn’t pause or affect other processes on other schedulers. This is not a simple topic, but theory is all here: http://gchandbook.org/

You have a grid of squares. Your aim is to draw a diagonal line through each square, and choose which way each line slants so that the following conditions are met:
Credit for this puzzle goes to Nikoli [8].

(in Japanese)
On Android, please touch for left click and long press for right click. Also note that where this manual refers to pressing a letter on the keyboard, the Android version has icons at the bottom of the screen instead (Control and Shift are not available). There is also an optional "Night mode" which uses darker colours in low light.
Left-clicking in a blank square will place a \
in it (a line leaning to the left, i.e. running from the top left of the square to the bottom right). Right-clicking in a blank square will place a /
in it (leaning to the right, running from top right to bottom left).
Continuing to click either button will cycle between the three possible square contents. Thus, if you left-click repeatedly in a blank square it will change from blank to \
to /
back to blank, and if you right-click repeatedly the square will change from blank to /
to \
back to blank. (Therefore, you can play the game entirely with one button if you need to.)
You can also use the cursor keys to move around the grid. Pressing the return or space keys will place a \
or a /
, respectively, and will then cycle them as above. You can also press /
or \
to place a /
or \
, respectively, independent of what is already in the cursor square. Backspace removes any line from the cursor square.
(All the actions described in section 2.1 are also available.)
These parameters are available from the ‘Custom...’ option on the ‘Type’ menu.
On platforms that support user preferences, the ‘Preferences’ option on the ‘Game’ menu will let you configure which way round the mouse buttons work.

BJ’s Wholesale Club Earnings: BJ Stock Falls 8% on Mixed Q3
BJ also has a poor outlook for 2019
BJ’s Wholesale Club (NYSE:BJ) earnings for the retail company’s third quarter of 2019 have BJ stock taking a beating on Thursday. The report includes adjusted per-share earnings of 41 cents. That’s better than Wall Street’s estimate of 40 cents. However, its revenue of $3.23 billion is a far cry from the $3.29 billion analysts’ were expecting.
Now for a more thorough look at the current BJ’s Wholesale Club earnings report.
- Adjusted earnings per share are up 5.13% from 39 cents in the same period of the year prior.
- Revenue is largely the same as what was reported during the same time last year.
- The BJ’s Wholesale Club earnings report also includes an operating income of $100.93 million.
- That’s 11.70% higher than the $90.33 million reported during the third quarter of 2018.
- Net income of $55.09 million is up 1.20% YoY from $54.43 million.
Christopher Baldwin, Chairman and Chief Executive Officer of BJ’s Wholesale Club, has this to say about the BJ stock earnings.
“We delivered solid margin improvement and continued earnings growth in the third quarter. We remain focused on executing against our strategic plan and transforming our business to be well positioned for the long-term. The board’s decision to authorize a stock repurchase program reflects the strength of our cash flow and confidence in our growth strategy and long-term outlook.”
More bad news for BJ stock comes from the 2019 guidance update in the BJ’s Wholesale Club earnings report. This has it expecting EPS between $1.44 and $1.48 on revenue of approximately $12.90 billion. Wall Street is looking for $1.49 per share and revenue of $13.28 billion in 2019.
BJ stock was down 7.62% as of Thursday afternoon.
As of this writing, William White did not hold a position in any of the aforementioned securities.

WhatsApp on Friday announced a three-month delay of a new privacy policy originally slated to go into effect on February 8th following widespread confusion over whether the new policy would mandate data sharing with Facebook.
The update does not in fact affect data sharing with Facebook with regard to user chats or other profile information; WhatsApp has repeatedly clarified that its update addresses business chats in the event a user converses with a company’s customer service platform through WhatsApp.
"We’ve heard from so many people how much confusion there is around our recent update. There’s been a lot of misinformation causing concern and we want to help everyone understand our principles and the facts," the company wrote in a new blog post published today.
Since 2016, WhatsApp has shared certain information with Facebook, including your phone number, unless you were one of the select few users who chose to opt out of data sharing while the option was still available that year
The company released a separate blog post this week trying to clear up the confusion, and it included a chart that specifies what information is protected and not shared when someone uses WhatsApp.

Latest Kali Linux News
Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing. It is maintained and funded by Offensive Security Ltd. Mati Aharoni, Devon Kearns and Raphaël Hertzog are the core developers.
Development
Kali Linux has over 600[3] preinstalled penetration-testing programs, including Armitage (a graphical cyber attack management tool), Nmap (a port scanner), Wireshark (a packet analyzer), John the Ripper password cracker, Aircrack-ng (a software suite for penetration-testing wireless LANs), Burp suite and OWASP ZAP web application security scanners.[4][5] Kali Linux can run natively when installed on a computer's hard disk, can be booted from a live CD or live USB, or it can run within a virtual machine. It is a supported platform of the Metasploit Project's Metasploit Framework, a tool for developing and executing security exploits.[4] It was developed by Mati Aharoni and Devon Kearns of Offensive Security through the rewrite of BackTrack, their previous information security testing Linux distribution based on Knoppix. The third core developer Raphaël Hertzog joined them as a Debian expert.[6][7] Kali Linux is based on Debian Testing. Most packages Kali uses are imported from the Debian repositories.[8] Kali Linux is developed using a secure environment with only a small number of trusted people that are allowed to commit packages, with each package being digitally signed by the developer. Kali also has a custom-built kernel that is patched for 802.11 wireless injection. This was primarily added because the development team found they needed to do a lot of wireless assessments.
Requirements
Kali Linux requires a minimum of 20GB hard disk space for installation.[9] A minimum of 1GB RAM for i386 and AMD64 architectures. A bootable CD-DVD drive or a USB stick. Supported platforms Kali Linux is distributed in 32-bit and 64-bit images for use on hosts based on the x86 instruction set and as an image for the ARM architecture for use on the Beagle Board computer and on Samsung's ARM Chromebook.[10] The developers of Kali Linux aim to make Kali Linux available for even more ARM devices.[7] Kali Linux is already available for BeagleBone Black, HP Chromebook, CubieBoard 2, CuBox, CuBox-i, Raspberry Pi, EfikaMX, Odroid U2, Odroid XU, Odroid XU3, Samsung Chromebook, Utilite Pro, Galaxy Note 10.1, and SS808.[11] With the arrival of Kali NetHunter, Kali Linux is also officially available on smartphones such as the Nexus 5, Nexus 6, Nexus 7, Nexus 9, Nexus 10, OnePlus One, and some Samsung Galaxy models. Kali Linux is available on Windows 10, on top of Windows Subsystem for Linux (WSL). The official Kali distribution for Windows can be downloaded from the Microsoft Store.[12] Features Kali Linux has a dedicated project set aside for compatibility and porting to specific Android devices, called Kali Linux NetHunter.[13] It is the first Open Source Android penetration testing platform for Nexus devices, created as a joint effort between the Kali community member “BinkyBear” and Offensive Security. It supports Wireless 802.11 frame injection, one-click MANA Evil Access Point setups, HID keyboard (Teensy like attacks), as well as Bad USB MITM attacks.[13] BackTrack (Kali's predecessor) contained a mode known as forensic mode, which was carried over to Kali via live boot. This mode is very popular for many reasons, partly because many Kali users already have a bootable Kali USB drive or CD, and this option makes it easy to apply Kali to a forensic job. When booted in forensic mode, the system doesn't touch the internal hard drive or swap space and auto mounting is disabled. However, the developers recommend that users test these features extensively before using Kali for real world forensics.[14]

Holby City fans devastated by stillbirth storyline as Lofty's baby tragically dies
Gut-wrenching...
by Helen FearLofty Chiltern and Helen experienced the horror of losing their baby last night, and Holby City viewers were in tears for them.
On Tuesday (November 19), Helen suffered a devastating stillbirth after she gave birth at just six months.
Read more: Coronation Street's Vicky Entwistle killed off in emotional Holby City scenes
Earlier in the episode, Helen looked forward to becoming a mum and hoped to start a new life with her holiday fling Lofty.
She told him she didn't want his husband Dom to be involved in the life of their baby and, confessing her love to him, asked Lofty to leave Dom for her instead.
Lofty tried to let Helen down gently, but became worried when she admitted she hadn't felt the baby kicking recently...
Read more: Holby City's Paul Bradley confirms special Christmas episode
When Lofty rushed Helen back to the hospital for an emergency scan, consultant obstetrician Fleur Fanshawe delivered the gut-wrenching news that she couldn't track a heartbeat.
She said: "The baby has died. Everyone's here for you. We are all here to support you."
As Lofty and Helen dealt with their own heartbreak and said goodbye to their son, William, viewers were sobbing at home.
One wrote: "This is horrible, I can't imagine what it's like to give birth to a stillborn baby. It's bad enough having a miscarriage early on. How on earth do you get over it? So sad #HolbyCity."
Another said: "Holby City got me in the guts tonight."
A third added: "Sad episode of Holby tonight, an angel baby."
"Holby City was really emotional tonight but was shown by some talented actors @leemeadofficial and @semadivad and the rest of the Holby cast," said one more.
Viewers know that Lofty had a holiday fling in America with Helen and had only recently come to terms with the fact she was carrying his baby.
In an interview with What's On TV, actor Lee Mead said: "Sadly, I have friends and family who've been through this and it's impossible to imagine what they must be feeling.
"For Lofty to have finally faced up to the fact he's going to be a dad, knowing the baby is on its way, then suddenly losing it, doesn't bear thinking about."
Simon Harper, executive producer of Holby City and Casualty, added: "The loss of the baby is terrible for Helen, and we also felt that the father's perspective is traditionally perhaps overlooked.
"Lofty and Dom's relationship gives us the chance to explore that. Lee, David and Verity all give beautifully pitched performances in a heartbreaking episode."

This is a school assignment so I don't feel like an extremely thorough explaination
of the system is academically honest. So The explaination here is lacking. The Lab documentation at the bottom in
sources should cover most of the topic I'm going to move onto assignments from other universities so I don't get expelled.
Memory for large datacenters was originally stored on large disks with laser scanners on them.
The memory would be broken up into sectors containing a number of bytes. To make this more efficient
a File allocation table was created. A FAT is a memory storage structure that uses an index table of corresponding disk
blocks to store files efficiently.They are still used in devices that require memory efficiency over file access speed, like NXP boards.
A FAT is technically challenging to implement. Sectors are stored in a scheme where the first sectors
act as indices to blocks. The blocks that are indexed to in the table are then linked to different indices.
In this example the table starts at sector 0. The files can occupy the 9 others.
The first available sector is 1 if the file needs more memory than sector 1 occupies it will proceeed to 1's
link in the FAT. 7 is the next sector that is free. It will continue until either
A. The sectors have adequately stored the file
B. The last sector is used in which case the file cannot be stored and should nothing should be written to any sector.
For a more detailed equation for links checkout Dr. Plank's description in the sources.
