We are no longer able to issue new DOI service accounts to non-University of California entities.
Can I get a new ARK account?
Yes.
Why are you changing EZID's service offering in this way?
DOI service providers have evolved considerably over the last 5-10 years, and after careful consideration, we have adopted the following new strategy direction: to endorse and support DataCite's long-term sustainability, while maintaining our own distinct role in the persistent identifier (PID) space.
What alternatives do I have for DOI services?
Option 1: Direct membership in DataCite. This is an especially good option if you seek a participatory role in the data citation and data curation community. In addition, we are working closely with DataCite to make sure popular EZID features (such as link checking and the usage dashboard) make their way into DataCite's feature set. If you'd like to know more, visit https://www.datacite.org/contact.html.
Option 2: Become a client of another DataCite member. Here is a list of current members: https://www.datacite.org/members.html.
Option 3: Use the services of a repository that provides DOIs, such as Dryad, Dataverse or figshare. This is a good option if you need only a very small number of DOIs.
Option 4: Become a client of Crossref. Crossref's annual member fee is based on the publishing revenue of the organization. For those organizations with less than $1M in publishing revenue the annual fee is $275. Crossref accepts data, text and preprints. You can explore Crossref's website for more information and when you are ready to apply for membership, complete this form: http://www.crossref.org/membership/join.
If you would like help assessing the differences between Crossref and DataCite services, please contact us
If I already have an EZID account, can I upgrade or change it?
You can certainly add new ARK services. If you have other questions, please contact us.
How does all of this affect University of California EZID account holders?
University of California clients and prospective clients are not affected by this change. If you have any questions, please contact us.

Questions
What is your name?
What is your occupation?
What do you like to do for fun?
What do you like to eat?


One major question in life: what should I eat today? And it's a hard one. If you study or work at NUS, being spoiled by numerous food outlets, then it can be a very hard one. Maybe you are one of those people spending such a long time deciphering your own thoughts, or you have one friend who just cannot figure his/her own taste palette out.
Itadakimasu~ is a telegram bot that help you to decide what to eat. The user can input a name of a canteen in NUS, and the bot will reply with a random meal reconmmendation.
I worked as a full stack developer. This project was done in a group of 2 members.

Mum cheers as son is jailed for beating dog to death
The mother of a man who beat his puppy to death cheered as her son was jailed after joining animal rights protesters in court.
Jon-Luc McLoughlin, 26, savagely punched 11-month-old Alsatian Lexi to death before dumping her body near some trees, which traumatised children later found.
His sentencing hearing was attended by around 25 animal rights campaigners and among them was the defendant’s mother and half-brother.
McLoughlin, from Poole, Dorset, was jailed for 16 weeks but his sibling, Alec Mackay said the sentence wasn’t long enough.
McLaughlin was also banned from owning animals for the rest of his life – a decision which was greeted with cheers from protesters, some of whom wore T-shirts with the words ‘Justice for Lexi’ printed on them.
He said: ‘My mum is grateful that he has gone down but I don’t think 16 weeks is long enough. If anything it should have been a year minimum.
‘If it was a human he would have gone down for a lot longer. We are all living creatures so he deserved to get more. I hope the dog comes back and bites him on his a**e.’

Poole Magistrates’ Court heard that McLoughlin had only owned Lexi for around a month before he killed her in a fit of rage.
During a police interview he initially lied by saying Lexi had been hit by a car but later confessed to killing her.
Matthew Knight, prosecuting for the RSPCA, said: ‘He punched the dog to death and dumped the body in some trees near his home.
‘It was found by locals and upset local children who saw it.
‘It is likely that the dog did not survive for long.’
When brought in for questioning, McLoughlin told officers: ‘I get very angry and I don’t know what came over me’.
James Moore, mitigating, said that the defendant was a ‘deeply troubled individual’ and asked for him to be offered rehabilitation.
He said: ‘We are a nation of animal lovers and this has caused a lot of anger in the whole community.
‘He lost control and acted in blind rage. We all to some extent sometimes lose control and regret it.
‘Mr McLoughlin has done that in a significant way and will have to live with that. However, he has not done it because he is depraved, he has done it because he is a deeply troubled individual.’
McLaughlin pleaded guilty to a charge of causing unnecessary suffering to a protected animal at a previous hearing.

Judge Stephen Nichols said: ‘Taking everything into account this warrants an immediate custodial sentence. This was a savage attack on Lexi.’
Michelle Sheriff, who led the animal rights campaign, said: ‘Lexi needed a voice and we were here for her. These things cannot be tolerated.
‘I would have liked to have seen him get more but it’s better than no prison at all.’
Graham Hammond, an RSPCA officer who investigated the case, said: ‘The man has a history of lashing out and we now feel we have got justice for that dog.
‘It sends a message to other people that these animals are protected and you need to look after them.
‘Any abuse to an animal is shocking especially when it leads to a death like this.
‘I suppose in some ways it is even more sad that it is a younger animal but whenever an pet is murdered it is incredibly shocking.’
Elisa Allen, a spokesman for fellow animal rights charity PETA, added: ‘Anyone capable of beating a puppy to death is likely to pose a serious threat to all living, feeling beings.

‘While PETA is relieved that this man is banned from keeping animals for life, it’s imperative that, in addition to his incarceration, he undergo counselling.
‘His anger-management and other psychological issues need to be addressed before he’s released back into society.’
McLoughlin was also told to pay a £115 victim surcharge.

--- layout: post title: "A pure command-line wizard" description: "An example of a small Abstract Syntax Tree written with F# syntactic sugar." date: 2017-07-17 12:04 UTC tags: [Software Design, Dependency Injection, F#, Functional Programming] --- {% include JB/setup %}
{{ page.description }}
In the previous article, you got an introduction to a functional command-line API in F#. The example in that article, however, was too simple to highlight its composability. In this article, you'll see a fuller example.
In previous articles, you can see variations on an HTTP-based back-end for an on-line restaurant reservation system. In this article, on the other hand, you're going to see a first attempt at a command-line client for the API.
Normally, an on-line restaurant reservation system would have GUIs hosted in web pages or mobile apps, but with an open HTTP API, a self-respecting geek would prefer a command-line interface (CLI)... right?!
Please enter number of diners: four Not an integer. Please enter number of diners: 4 Please enter your desired date: My next birthday Not a date. Please enter your desired date: 2017-11-25 Please enter your name: Mark Seemann Please enter your email address<EMAIL_ADDRESS>{Date = 25.11.2017 00:00:00 +01:00; Name = "Mark Seemann"; Email =<EMAIL_ADDRESS>Quantity = 4;}
In this incarnation, the CLI only collects information in order to dump a rendition of an F# record on the command-line. In a future article, you'll see how to combine this with an HTTP client in order to make a reservation with the back-end system.
Notice that the CLI is a wizard. It leads you through a series of questions. You have to give an appropriate answer to each question before you can move on to the next question. For instance, you must type an integer for the number of guests; if you don't, the wizard will repeatedly ask you for an integer until you do.
You can develop such an interface with the commandLine
computation expression from the previous article.
There are four steps in the wizard. The first is to read the desired quantity from the command line:
// CommandLineProgram<int> let rec readQuantity = commandLine { do! CommandLine.writeLine "Please enter number of diners:" let! l = CommandLine.readLine match Int32.TryParse l with | true, dinerCount -> return dinerCount | _ -> do! CommandLine.writeLine "Not an integer."  This enables you to use do!
expressions and let!
bindings to compose smaller CommandLineProgram
values, such as CommandLine.writeLine
and CommandLine.readLine
(both shown in the previous article).
After prompting the user to enter a number, the program reads the user's input from the command line. While CommandLine.readLine
is a CommandLineProgram<string>
value, the let!
binding turns l
into a string
value. If you can parse l
as an integer, you return the integer; otherwise, you recursively return readQuantity
.
The readQuantity
program will continue to prompt the user for an integer. It gives you no option to cancel the wizard. This is a deliberate simplification I did in order to keep the example as simple as possible, but a real program should offer an option to abort the wizard.
The function returns a CommandLineProgram<int>
value. This is a pure value containing an Abstract Syntax Tree (AST) that describes the interactions to perform. It doesn't do anything until interpreted. Contrary to designing with Dependency Injection and interfaces, however, you can immediately tell, from the type, that explicitly delimited impure interactions may take place within that part of your code base.
When you've entered a proper number of diners, you proceed to enter a date. The program for that looks similar to readQuantity
:
// CommandLineProgram<DateTimeOffset> let rec readDate = commandLine { do! CommandLine.writeLine "Please enter your desired date:" let! l = CommandLine.readLine match DateTimeOffset.TryParse l with | true, dt -> return dt | _ -> do! CommandLine.writeLine "Not a date." return! readDate }
The readDate
value is so similar to readQuantity
that you might be tempted to refactor both into a single, reusable function. In this case, however, I chose to stick to the rule of three.
Reading the customer's name and email address from the command line is easy, as no parsing is required:
// CommandLineProgram<string> let readName = commandLine { do! CommandLine.writeLine "Please enter your name:" return! CommandLine.readLine } // CommandLineProgram<string> let readEmail = commandLine { do! CommandLine.writeLine "Please enter your email address:" return! CommandLine.readLine }
Both of these values unconditionally accept whatever you write when prompted. From a security standpoint, all input is evil, so in a production code base, you should still perform some validation. This, on the other hand, is demo code, so with that caveat, it accepts all strings you might type.
These values are similar to each other, but once again I invoke the rule of three and keep them as separate values.
Together with the general-purpose command line API, the above values are all you need to compose the wizard. In this incarnation, the wizard should collect the information you type, and create a single record with those values. This is the type of record it must create:
type Reservation = { Date : DateTimeOffset Name : string Email : string Quantity : int }
You can easily compose the wizard like this:
// CommandLineProgram<Reservation> let readReservationRequest = commandLine { let! count = readQuantity let! date = readDate let! name = readName let! email = readEmail return { Date = date; Name = name; Email = email; Quantity = count } }
There's really nothing to it. As all the previous code examples in this article, you compose the readReservationRequest
value entirely inside a commandLine
expression. You use let!
bindings to collect the four data elements you need, and once you have all four, you can return a Reservation
value.
You may have noticed that no code so far shown define functions; they are all values. They are small program fragments, expressed as ASTs, composed into slightly larger programs that are still ASTs. So far, all the code is pure.
In order to run the program, you need an interpreter. You can reuse the interpreter from the previous article when composing your main
function:
[<EntryPoint>] let main _ = Wizard.readReservationRequest |> CommandLine.bind (CommandLine.writeLine << (sprintf "%A")) |> interpret 0 // return an integer exit code
Notice that most of the behaviour is defined by the above Wizard.readReservationRequest
value. That program, however, returns a Reservation
value that you should also print to the command line, using the CommandLine
module. You can achieve that behaviour by composing Wizard.readReservationRequest
with CommandLine.writeLine
using CommandLine.bind
. Another way to write the same composition would be by using a commandLine
computation expression, but in this case, I find the small pipeline of functions easier to read.
When you bind two CommandLineProgram
values to each other, the result is a third CommandLineProgram
. You can pipe that to interpret
in order to run the program. The result is an interaction like the one shown in the beginning of this article.
In this article, you've seen how you can create larger ASTs from smaller ASTs, using the syntactic sugar that F# computation expressions afford. The point, so far, is that you can make side-effects and non-deterministic behaviour explicit, while retaining the 'normal' F# development experience.
In Haskell, impure code can execute within an IO
context, but inside IO
, any sort of side-effect or non-deterministic behaviour could take place. For that reason, even in Haskell, it often makes sense to define an explicitly delimited set of impure operations. In the previous article, you can see a small Haskell code snippet that defines a command-line instruction AST type using Free
. When you, as a code reader, encounter a value of the type CommandLineProgram String
, you know more about the potential impurities than if you encounter a value of the type IO String
. The same argument applies, with qualifications, in F#.
When you encounter a value of the type CommandLineProgram<Reservation>
, you know what sort of impurities to expect: the program will only write to the command line, or read from the command line. What if, however, you'd like to combine those particular interactions with other types of interactions?
Read on.

4.9-Magnitude Earthquake Hits Southern France - Report
Early on Monday morning, an earthquake hit southern France with shock going from Nîmes to Montpellier via Bagnols-sur-Cèze.
The National Seismic Monitoring Network has reported that two earthquakes measuring 5.1 and 5.7 were detected. According to French Le Progrès outlet, the epicentre is located 10 km from Montélimar, in the Drôme, for the first, and the second 25 km from Aubenas, Ardèche.
There are no immediate reports of major damages or injuries, though people living in the affected area have been turning to Twitter to share photos and opinions on the earthquake.


Manifest version 1 was deprecated in Chrome 18, and support will be phased out according to the manifest version 1 support schedule. The changes from version 1 to version 2 fall under two broad categories: API changes and Security changes.
This document provides checklists for migrating your Chrome extensions from manifest version 1 to version 2, followed by more detailed summaries of what these changes mean and why they were made.

property has been replaced
with Port.sender
.chrome.extension.getTabContentses()
and the
chrome.extension.getExtensionTabs()
APIs have been replaced
by chrome.extension.getViews( { "type" : "tab" } )
.There are a number of security-related changes that accompany the move from manifest version 1 to version 2. Many of these changes stem from Chrome’s adoption of Content Security Policy; you should read more about this policy to understand its implications.
Due to the use of Content Security Policy, you can no longer use <script> tags that are inline with the HTML content. These must be moved to external JS files. In addition, inline event handlers are also not supported. For example, suppose you had the following code in your extension:
<html> <head> <script> function myFunc() { ... } </script> </head> </html>
This code would cause an error at runtime.
To fix this, move <script> tag contents to external files
and reference them with a src=’path_to_file.js’
attribute.
Similarly, inline event handlers, which are a common occurrence and convenience feature used by many Web developers, will not execute. For example, consider common instances such as:
<body onload="initialize()"> <button onclick="handleClick()" id="button1">
These will not work in manifest V2 extensions.
Remove the inline event handlers,
place them in your external JS file and use addEventListener()
to register event handlers for them instead.
For example, in your JS code, use:
window.addEventListener("load", initialize); ... document.getElementById("button1").addEventListener("click",handleClick);
This is a much cleaner way of separating your extension’s behavior from its user interface markup.
There are some scenarios where your extension might embed content that can be used externally or come from an external source.
Extension content in web pages:
If your extension embeds resources (like images, script, CSS styles, etc)
that are used in content scripts that are injected into web pages,
you need to use the
web_accessible_resources property
to allowlist these resources so that external Web pages can use them:
{ ... "web_accessible_resources": [ "images/image1.png", "script/myscript.js" ], ... }
Embedding external content:
The Content Security Policy only allows local script
and objects to loaded from your package,
which prevents external attackers from introducing unknown code to your extension.
However, there are times when you want to load externally served resources,
such as jQuery or Google Analytics code.
There are two ways to do this:
{ ..., "content_security_policy": "script-src 'self' https://ssl.google-analytics.com; object-src 'self'", ... }
Perhaps one of the biggest changes in the new manifest v2 scheme is
that extensions can no longer use dynamic script evaluation techniques like
eval()
or new Function()
,
or pass strings of JS code to functions
that will cause an eval()
to be used,
like setTimeout()
.
In addition, certain commonly used JavaScript libraries,
such as Google Maps and certain templating libraries,
are known to use some of these techniques.
Chrome provides a sandbox for pages to run in their own origin,
which are denied access to chrome.* APIs.
In order to use eval()
and the like under the new Content Security Policy:
postMessage()
to communicate with the sandboxed page.For more details on how to do this, see the Sandboxing Eval documentation.
The changes in manifest version 2 are designed to guide developers toward building more secure and robustly-architected extensions and apps. To see a complete list of changes from manifest version 1 to version 2, see the manifest file documentation. For more information about using sandboxing to isolate unsafe code, read the sandboxing eval article. You can learn more about Content Security Policy by visiting our extensions-related tutorial and a good introduction on HTML5Rocks.

Describes an API.
The Desc type describes an entire API.
Creates a Desc.
The new constructor creates a new Desc.
Gets data about a class.
The Class method returns the class of the API corresponding to the name class, or nil if the class does not exist.
Gets whether a tag is set for a class.
Returns whether tag is set for the class corresponding to the name class. Returns nil if the class does not exist.
Gets a list of class names.
The Classes method returns a list of names of all the classes of the API.
Returns a deep copy of the Desc.
The Copy method returns a deep copy of the Desc.
Gets the difference between two descriptors.
The Diff method compares the root descriptor with another and returns the differences between them. A nil value for next is treated the same as an empty descriptor. The result is a list of actions that describe how to transform the descriptor into next.
Gets data about an enum.
The Enum method returns the enum of the API corresponding to the name enum, or nil if the enum does not exist.
Gets data about an enum item.
The EnumItem method returns the enum item of the API corresponding to the enum name enum and item name item, or nil if the enum or item does not exist.
Gets whether a tag is set for an enum item.
Returns whether tag is set for the enum item corresponding to the name item of the enum named enum. Returns nil if the enum or item does not exist.
Gets a list of item names of an enum.
The Classes method returns a list of names of all the items of the enum corresponding to the name enum. Returns nil if the enum does not exist.
Gets whether a tag is set for an enum.
Returns whether tag is set for the enum corresponding to the name enum. Returns nil if the enum does not exist.
Gets enum values generated from the descriptor.
The EnumTypes method returns a set of enum values generated from the current state of the Desc. These enums are associated with the Desc, and may be used by certain properties, so it is important to generate them before operating on such properties. Additionally, EnumTypes should be called after modifying enum and enum item descriptors, to regenerate the enum values.
The API of the resulting enums matches that of Roblox's Enums type. A common pattern is to assign the result of EnumTypes to the "Enum" variable so that it matches Roblox's API:
Enum = desc:EnumTypes()
print(Enum.NormalId.Front)
Gets a list of enum names.
The Enums method returns a list of names of all the enums of the API.
Gets data about a class member.
The Member method returns the class member of the API corresponding to the class name enum and member name item, or nil if the class or member does not exist.
Gets whether a tag is set for a class member.
Returns whether tag is set for the class member corresponding to the name member of the class named class. Returns nil if the class or member does not exist.
Gets a list of member names of a class.
Returns whether tag is set for the class member corresponding to the name member of the class named class. Returns nil if the class or member does not exist.
Transforms the descriptor.
The Patch method transforms the root descriptor according to a list of actions. Each action in the list is applied in order. Actions that are incompatible are ignored.
Sets data about a class.
The SetClass method sets the fields of the class corresponding to the name class. If the class already exists, then only non-nil fields are set. Fields with the incorrect type are ignored. If desc is nil, then the class is removed.
Returns false if desc is nil and no class exists. Returns true otherwise.
Sets data about an enum.
The SetEnum method sets the fields of the enum corresponding to the name enum. If the enum already exists, then only non-nil fields are set. Fields with the incorrect type are ignored. If desc is nil, then the enum is removed.
Returns false if desc is nil and no enum exists. Returns true otherwise.
Sets data about an enum item.
The SetEnumItem method sets the fields of the enum item corresponding to the name item of the enum named enum. If the item already exists, then only non-nil fields are set. Fields with the incorrect type are ignored. If desc is nil, then the enum is removed.
Returns nil if the enum does not exist. Returns false if desc is nil and no item exists. Returns true otherwise.
Sets data about a class member.
The SetMember method sets the fields of the member corresponding to the name member of the class named class. If the member already exists, then only non-nil fields are set. Fields with the incorrect type are ignored. If desc is nil, then the member is removed.
Returns nil if the class does not exist. Returns false if desc is nil and no member exists. Returns true otherwise.

HUCK said: "Tom, we can slope, if we can find a rope. The window ain't high from the ground."
"Shucks! what do you want to slope for?"
"Well, I ain't used to that kind of a crowd. I can't stand it. I ain't going down there, Tom."
"Oh, bother! It ain't anything. I don't mind it a bit. I'll take care of you."
Sid appeared.
"Tom," said he, "auntie has been waiting for you all the afternoon. Mary got your Sunday clothes ready, and everybody's been fretting about you. Say—ain't this grease and clay, on your clothes?"
"Now, Mr. Siddy, you jist 'tend to your own business. What's all this blow–out about, anyway?"
"It's one of the widow's parties that she's always having. This time it's for the Welshman and his sons, on account of that scrape they helped her out of the other night. And say—I can tell you something, if you want to know."
"Well, what?"
"Why, old Mr. Jones is going to try to spring something on the people here to–night, but I overheard him tell auntie to–day about it, as a secret, but I reckon it's not much of a secret now. Everybody knows —the widow, too, for all she tries to let on she don't. Mr. Jones was bound Huck should be here—couldn't get along with his grand secret without Huck, you know!"
"Secret about what, Sid?"
"About Huck tracking the robbers to the widow's. I reckon Mr. Jones was going to make a grand time over his surprise, but I bet you it will drop pretty flat."
Sid chuckled in a very contented and satisfied way.
"Sid, was it you that told?"
"Oh, never mind who it was. SOMEBODY told—that's enough."
"Sid, there's only one person in this town mean enough to do that, and that's you. If you had been in Huck's place you'd 'a' sneaked down the hill and never told anybody on the robbers. You can't do any but mean things, and you can't bear to see anybody praised for doing good ones. There—no thanks, as the widow says"—and Tom cuffed Sid's ears and helped him to the door with several kicks. "Now go and tell auntie if you dare—and to–morrow you'll catch it!"
Some minutes later the widow's guests were at the supper–table, and a dozen children were propped up at little side–tables in the same room, after the fashion of that country and that day. At the proper time Mr. Jones made his little speech, in which he thanked the widow for the honor she was doing himself and his sons, but said that there was another person whose modesty—
And so forth and so on. He sprung his secret about Huck's share in the adventure in the finest dramatic manner he was master of, but the surprise it occasioned was largely counterfeit and not as clamorous and effusive as it might have been under happier circumstances. However, the widow made a pretty fair show of astonishment, and heaped so many compliments and so much gratitude upon Huck that he almost forgot the nearly intolerable discomfort of his new clothes in the entirely intolerable discomfort of being set up as a target for everybody's gaze and everybody's laudations.
The widow said she meant to give Huck a home under her roof and have him educated; and that when she could spare the money she would start him in business in a modest way. Tom's chance was come. He said:
"Huck don't need it. Huck's rich."
Nothing but a heavy strain upon the good manners of the company kept back the due and proper complimentary laugh at this pleasant joke. But the silence was a little awkward. Tom broke it:
"Huck's got money. Maybe you don't believe it, but he's got lots of it. Oh, you needn't smile—I reckon I can show you. You just wait a minute."
Tom ran out of doors. The company looked at each other with a perplexed interest—and inquiringly at Huck, who was tongue–tied.
"Sid, what ails Tom?" said Aunt Polly. "He—well, there ain't ever any making of that boy out. I never—"
Tom entered, struggling with the weight of his sacks, and Aunt Polly did not finish her sentence. Tom poured the mass of yellow coin upon the table and said:
"There—what did I tell you? Half of it's Huck's and half of it's mine!"
The spectacle took the general breath away. All gazed, nobody spoke for a moment. Then there was a unanimous call for an explanation. Tom said he could furnish it, and he did. The tale was long, but brimful of interest. There was scarcely an interruption from any one to break the charm of its flow. When he had finished, Mr. Jones said:
"I thought I had fixed up a little surprise for this occasion, but it don't amount to anything now. This one makes it sing mighty small, I'm willing to allow."
The money was counted. The sum amounted to a little over twelve thousand dollars. It was more than any one present had ever seen at one time before, though several persons were there who were worth considerably more than that in property.

While Boost.Build V2 is based on the same ideas as Boost.Build V1, some of the syntax was changed, and some new important features were added. This chapter describes most of the changes.
In V1, toolsets were configured by environment variables. If you
wanted to use two versions of the same toolset, you had to create a new
toolset module that would set the variables and then invoke the base
toolset. In V2, toolsets are configured by the
using
, and you can easily configure several
versions of a toolset. See the section called “Configuration” for details.
Probably one of the most important differences in V2 Jamfiles is
the use of project requirements. In V1, if several targets had the same
requirements (for example, a common #include
path), it was necessary to
manually write the requirements or use a helper rule or template target. In V2, the
common properties can be specified with the requirements
project
attribute, as documented in the section called “Projects”.
Usage requirements
also help to simplify Jamfiles.
If a library requires
all clients to use specific #include
paths or macros when compiling
code that depends on the library, that information can be cleanly
represented.
The difference between lib
and dll
targets in V1 is completely
eliminated in V2. There's only one library target type, lib
, which can create
either static or shared libraries depending on the value of the
<link>
feature. If your target should be only built in one way, you
can add <link>shared
or <link>static
to its requirements.
The syntax for referring to other targets was changed a bit. While in V1 one would use:
exe a : a.cpp <lib>../foo/bar ;
the V2 syntax is:
exe a : a.cpp ../foo//bar ;
Note that you don't need to specify the type of other target, but the
last element should be separated from the others by a double slash to indicate that
you're referring to target bar
in project ../foo
, and not to
project ../foo/bar
.
The command line syntax in V2 is completely different. For example
bjam -sTOOLS=msvc -sBUILD=release some_target
now becomes:
bjam toolset=msvc variant=release some_target
or, using implicit features, just:
bjam msvc release some_target
See the reference for a complete description of the syntax.

At first you might think logarithms are hard to understand, but after awhile you will get the hang of it. Logarithms are a quantity representing the power to which a fixed number or the base, must be raised to produce a given number. An important thing to know is logs ALWAYS relate back to exponents.
An example would be, two to the third power equals eight. You would change it into a log by making it; log base two of eight is equal to three.
There is also a logarithm known as the common log where it has a base of ten. When you have a common log you don’t have to write the base, because it is already known that there is an imaginary ten is there. If you have ten to the third power equals ten it will change to log one thousand equals 3.
Fractions might come into play, which might scare you into thinking that it’s going to be really difficult to solve. In reality you can solve them into the same way, you just have to get used to the idea of it.
”You could probably prove, by judicious use of logarithms and congruent triangles, that real life is a lot more like soap opera than most people will admit.” - Molly Ivins
Logarithms may seem difficult at first, but with a little patience and practice you can get the hang of it in no time. If you are having a difficult time trying to remember what goes where, you can come up with a rhyme or saying to help you remember.

{% extends "layout.html" %} {% block page %}
We encountered an error processing your request, sorry about that.


It is expected that there is exactly one block on initialization. This is the remaining space (< 64K) within the last page after static data.
It is expected that if two adjacent blocks of size K are freed, the merged block doesn't go into the first level list for K*2 because its size is actually larger than that (K + OVERHEAD + K).
It is expected that if memory grows beyond 1GB, that even if all blocks are free'd there are at least two (or even three if the largest block is in the middle) remaining blocks, because a single block must not be larger than 1GB.
It is expected that after other operations have already been performed, being able to allocate 1GB can't be guaranteed anymore, even if there should be enough space left in absolute terms, if prior subdivision prevents it.
It is expected that the second level 0 in first level 0 isn't ever used due to alignment guarantees. Smallest block is 32 bytes (16 bytes overhead + 16 bytes payload if used, respectively linking information if free) in this implementation.
Implementation constants:? bits alignment, ? bits first level, ? bits second level, ? B overhead
First level bitmap
The first level map is a bitmap determining whether free blocks exist in at least one of its respective second levels. In this implementation, the first bit indicates whether a small block (< 256B) exists. Each bit doubles the size.
Second level maps
Second level maps subdivide each first level into multiple lists of subsizes. Each one works similar to the first level bitmap.
Heads
The heads of the actual free lists, one per second level per first level. Values here are pointers into memory. Last item is the address of the special zero-size "used" tail block, which is usually the end of WASM memory minus block overhead.
Allocator
Chose a size to allocate. Annotated list indexes depend on implementation constants but match those of this implementation.
Small blocks:
...
(δ ≙ block overhead)
Common blocks:
(e.g. allocate 3, free middle, check second level)
Large blocks:
Segments
Allocations performed above are tracked here so you can free them again. Note that TLSF alone does not keep track of used blocks (unless free'd and put in a free list again). It is expected that adjacent free blocks become merged automatically.

An LDM system's main program is the binary executable ldmd. This program
The pqact utility reads data-products from the product-queue and disposes of them according to user-configurable instructions. One or more instances of this program are, typically, started by the top-level ldmd process as the result of EXEC entries in the LDM configuration-file, ldmd.conf. Instructions for the disposition of data-products are contained in a pqact configuration-file.
Certain instructions in the pqact configuration-file cause the pqact utility to spawn child processs to aid in the disposition of data-products. These instructions are the pqact PIPE action and the pqact EXEC action.
Typically, pqact processes are terminated by reception of a SIGINT or SIGTERM from the top-level ldmd process.
When a pqact process terminates, it saves the insertion-time of the last, successfully-processed data-product in a file. The pathname of the file is that of the pqact configuration-file with ".state" appended. This allows a subsequent pqact process that uses the same configuration-file to start processing where the previous process stopped. It also means only one pqact process should use any configuration-file.
An LDM data-product ingester is a program that creates data-products and inserts them into the LDM product-queue using the pq(3) API. Such a program has the following characteristics:
It is, ultimately, irrelevant how ingesters obtain the data from which they create data-products because such information is lost once the data-product has been created and inserted into the product-queue. Data sources that have been used include the following: serial ports, files, and pseudo-random number generators.
The LDM package comes with the following ingesters. While some are useful in their own right, their primary purpose is to provide examples of how to write ingesters.
An LDM data-product decoder is a program that reads data-product data from standard input and disposes of the data in some fashion -- often by writing the data into a file that is specific to an analysis package (e.g., McIDAS or GEMPAK). Such programs have the following characteristics:
Because a decoder doesn't have a useful standard output or standard error, a decoder that depends them (to report errors, for example) will not function correctly. An easy workaround exists, however: wrap the decoder in a simple shell script that redirects such output into files. The following shell script is an example:
#!/bin/sh exec 1><stdout> exec 2><stderr> <decoder> "$@"
where:
Decoders that are, themselves, shell scripts, may use the LDM package's ulogger utility to log error messages. For example, the following, simple shell script concatenates its standard input to a file -- reproducing the effect of the pqact(1) FILE action:
progname=`basename $0` if test $# -ne 1; then ulogger -p FATAL "$progname: Usage: $progname <file>" else file=$1 if ! cat >> "$file"; then ulogger -p FATAL "$progname: Couldn't append to file \"$file\"" fi fi
By default, the ulogger utility logs at the NOTE level. It also uses the same logging mechanism as the other LDM programs; consequently, it will log to the LDM log file by default unless overridden by the "-l file" option.
The ldmadmin utility is a Perl-5 script intended for high-level administration of an LDM system. The script acts as a facade for more primitive utilities -- coordinating their use for the sake of convenience. The things you can do with the ldmadmin script include the following:
| Command | Action |
|---|---|
| ldmadmin start | Start the LDM system |
| ldmadmin stop | Stop the LDM system |
| ldmadmin restart | Stop then restart the LDM system |
| ldmadmin isrunning | Determine if the LDM system is running |
| ldmadmin mkqueue | Create the product-queue |
| ldmadmin delqueue | Delete the product-queue |
| ldmadmin watch | Watch the most recent data-products arrive in the product-queue |
| ldmadmin pqactcheck | Check the syntax of all pqact configuration-files associated with active EXEC pqact entries in the LDM configuration-file. |
| ldmadmin newlog | Rotate the LDM logfiles |
| ldmadmin addmetrics | Accumulate performance metrics on the LDM system. |
| ldmadmin plotmetrics | Plot performance metrics on the LDM system. |
| ldmadmin newmetrics | Rotate the performance metrics data-files. |
| ldmadmin check | Check that everything is OK with the LDM system. Usually executed periodically via the crontab utility. |
Utilities that are included in the LDM package but are less important than the separately-documented ones above include the following:
| Utility | Description |
|---|---|
| feedme | Requests data-products from an upstream LDM and writes them to standard output. Deprecated. |
| ldmping | Temporarily connects to an upstream LDM to test its availability. |
| ldmsend | Sends files as LDM data-products to a downstream LDM using HEREIS messages. |
| notifyme | Requests data-product metadata from an upstream LDM and, optionally, writes the metadata to an LDM logfile. |
| plotMetrics | Plots performance metrics on the LDM system. |
| pqcat | Reads once through a product-queue and writes the data-products to a file or to standard output. Useful for ensuring that a product-queue isn't corrupt. |
| pqcheck | Checks the writer-counter in the product-queue. Useful for ensuring that a product-queue isn't corrupt. |
| pqcopy | Copies data-products from one product-queue to another. |
| pqcreate | Creates an empty product-queue. |
| pqexpire | Deletes old data-products from a product-queue. Deprecated. |
| pqmon | Prints a summary of the state of a product-queue. |
| pqsend | Reads a product-queue and sends the data-products to a downstream LDM.Waits for more data-products. |
| pqsurf | Reads data-products that are composite WMO surface bulletins from the product-queue, splits them into individual bulletins, inserts them as data-products into a separate product-queue, and processes the individual bulletins similar to pqact. Deprecated. |
| pqutil | Interactive program for accessing the product-queue. |
| regex | Utility for testing extended regular expressions (ERE). |
| regutil | Manages the LDM registry. |
| rtstats | Monitors the product-queue and periodically sends summary statistics to a downstream LDM (which, for the IDD, is at the Unidata Program Center). |
| scour | crontab-driven utility for deleting old data-files based on pathname patterns and retention-times. |
| wasReceived | Indicates if a data-product matching specifiable selection criteria has been inserted into the product-queue. |
| uldbutil | Accesses the transitory database of upstream LDM processes. |

: A Ruby block is just a bit of code that can be excuted.

my_nums.collection { |num| num ** 2 }
# return [1,4,9]
my_nums.collection! { |num| num ** 2 }

def double(n)
puts "Ori input is #{n}"
yield(n)
end
double(2) { |n| puts n *2}
Proc
Procs are easy to define! You just call Proc.new
and pass in the block you want to save.
- Procs are full-fledged object.
- This prevents you from haveing to retype the contents of your block every time you need to execute a particular bit of code.
multiples_of_3 = Proc.new do |n|
n % 3 == 0
end
(1..100).to_a.select(&multiples_of_3)
multiples_of_3.call
Lambda
lambda { |param| block }
lambda { puts "Hello!" }
Lambda VS. Proc
- A lambda checks the number of arguments passed to it , while a proc does not. This means that a lambda will throw an error if you pass it the worng number of arguments, whereas a proc will ignore unexpected arguments and assign
nil
to any that are missing. - When a lambda returns , it passes control back to the calling methods; when a proc returns, it does so immediately, without going back to the calling methods.

Class Variable
- We can create class variable by starting a variable name with two @
- Only one copy of a class variable shared by all instances of a class.
class MyClass

end
- class variable should use a class method to grab it.
Inheritance
class ChildClass < FatherClass
end
- ChildClass is called: derived class Or subclasss
- FatherClass is called: parent or superclass
- derived class can only have one superclass, not support multiple inheritance

# Some stuff
end
end
end
class Email<Message
def initialize(from, to)

end
end
Public&Private
- Note that everything after the public keyword through the end of the class definition will now be public unless we say otherwise.
- Another way to say this is that the method cannot be called with an explicit receiver.
- In order to access private information, we have to create public methods that know how to get it.
Module
You can think of a Module as a toolbox that contains a set of methods and constants.
One of the main purposes of modules is to seprate methods and constants into named spaces. That is called namespacing
.
- It dosent’t make sense to include variables in modules, since variables change.

Indians in Ghana are amongst the most respected community. The Indo-Ghana ties have been in existence for more than 100 years now and the Indo-Ghana relationship has always been warm and friendly. The strong foundation was further solidified by India’s first Prime Minister Jawaharlal Nehru and Ghana’s first President Kwame Nkrumah, two great leaders who enjoyed a special kind of friendship and a similar vision. Both were influential and instrumental in the formation of the Non-Aligned Movement in 1961.Ghana has a relatively small but growing vibrant Indian Community, compared to Nigeria, Kenya & Uganda, and South Africa.

© 2011 webinos consortium, www.webinos.org.
This document describes the tools assessed and used for Webinos APIs specification.
First draft for initial discussion.
This document describes the tools for API specification that Webinos project assessed and the toolchain that Webinos has put in place to ease and automate the API specification work.
WAC and BONDI API specifications were mostly created using a toolchain that converts annotated WebIDL files into HTML documentation.
API Authors edit a WebIDL file in which additional information is included through comments following a similar syntax to Doxygen. These Doxygen-like comments provide information about the meaning of the interfaces, attributes, methods and input arguments. Futhermore, some security aspects (e.g. which methods are security sensitive) can be also documented through appropriate keywords. Detailed information about the supported syntax is available at: Aplix Website.
The annotated WebIDL (also known as widl) can be converted through the widlproc tool into an XML file. The widlproc tool is an opensource tool developed by Aplix that is licensed through Apache 2. The source code is also available at a repository hosted by Aplix.
The XML file generated by widlproc can then be converted through an XSL into an HTML file with customised styling based on CSS. Two different styles created based in similar widl can be found at:
This approach is quite flexible and scriptable: e.g. it is very easy to create scripts that process many widls and based on that auto-generates the documentation. For instance, in WAC we have some hooks in SVN that update the documentation every time a widl is committed to the database. Additionally, Webinos could create their own spec Look&Feel by tweaking the XSL and CSS used for HTML generation and styling.
As an XML is generated in the intermediate step, it should be relative easy to create the documentation in alternative formats to HTML (e.g. ePub or PDF). Alternatively, that XML could be also used for generating the stubs of the code for the API implementation or for generating SDK plugins.
Some drawbacks of this toolchain:
However, if Webinos believe this toolchain is the right way forward, the two first drawbacks could be overcome as Webinos have access to the source code. Furthermore, Webinos could also contribute back any improvements made in the wildproc tool to the community.
ReSpec is a Javascript based tool created by Robin Berjon that allows editors to write a specification focusing on the actual features and correctness, while needing to pay as little attention as possible to issues pertaining to styling. This tool allows spec editors to edit directly an HTML file that should make use of the Respec.js script library. When the HTML is rendered by a browser, the appropriate styling is applied by Respec.js.
The documentation for this tool is available at W3C site
Although this mechanism is useful when editing the spec, when it is ready for publication, the tool also allows to save a snapshot of the spec with no scripting at all, so it is a "static" HTML page.
This tool has been mostly used in the W3C DAP API Specs, for instance the messaging API.
The source code is publicly available and is licensed through W3C License .
A new version of ReSpec (ReSpec2) is also in development and is supposed to offer a more modular approach, making it more customizable.
During BONDI development, it was acknowledged that apart from enforcing WebIDL syntax, further checkings should be done in the specification, for instance:
In order to do it, ACCESS created a tool based on PHP that extracted the code from the same widls used in conjunction to widlproc to populate a database. The information of database was processed for two different purposes:
The W3C WebIDL checker takes a similar approach, and allows to extract WebIDL fragments from HTML pages, and run in addition to syntactic checks a set of more advanced checks as defined by the prose of the WebIDL specification.
The WebIDL checker builds upon widlproc through an open-source Python script.
All the initiatives that are defining EcmaScript APIs are using WebIDL, Webinos decided to follow the same approach and use WebIDL to specify the interfaces.
With regards to the authoring tool for creating the specification, a wildproc toolchain similar to what was used by WAC and BONDI was seleced as the preferred way forward.
Webinos has already made contributions to widlproc repository in order to support the latest Webidl drafts so that the Webinos could write their specifications using the latest available WebIDL versions.
Based in the updated widlproc tool, Webinos has implemented a toolchain that gets all the annotated WebIDL from a git repository, processes them and creates a set of API specifications that are made publicly available at the Webinos API Specification Home Page

In 2002, Tyskie Gronie won The Brewing Industry International Awards, receiving the two most prestigious awards - Gold Medal and Grand Prix.
In 2005, in Munich at a global beer fair hosted by Drink Tec, Tyskie again received the Grand Prix.
In 2011, Tyskie received the Gold Medal du Monde Selection – International Institute for Quality Selections.
What's Unique???
Tyskie is a pattern Gronie taste lager in the world. Perfectly composed flavor profile provides a strong bitterness and malt fully, while satisfying the desire.
Tyskie is made from carefully selected ingredients: malted barley, hops and water, using natural yeast in the beer fermentation.

Seasoned drinker senses in the notes of malt, delicate aroma of hops, and even touches of apple and banana. Gronie years gaining recognition in Poland and in the world.

The sweetness in the 5.3% ABV Tyskie is undercut by some bitterness at the end, which helps balance out the lager.
As the only Polish beer, twice won the "Beer Oscars" - Grand Prix at The British Brewing Industry Awards, the most prestigious beer competition in the world.


Rack, a modular Ruby webserver interface ¶ ↑
Rack provides a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between (the so-called middleware) into a single method call.
The exact details of this are described in the Rack specification, which all Rack applications should conform to.
Supported web servers¶ ↑
The included handlers connect all kinds of web servers to Rack:
-
Mongrel
-
EventedMongrel
-
SwiftipliedMongrel
-
FCGI
-
CGI
-
SCGI
-
LiteSpeed
-
Thin
These web servers include Rack handlers in their distributions:
-
Ebb
-
Fuzed
-
Glassfish v3
-
Phusion Passenger (which is mod_rack for Apache and for nginx)
-
Puma
-
Rainbows!
-
Reel
-
Unicorn
-
unixrack
-
uWSGI
-
yahns
-
Zbatery
Any valid Rack app will run the same on all these handlers, without changing anything.
Supported web frameworks¶ ↑
These frameworks include Rack adapters in their distributions:
-
Camping
-
Coset
-
Espresso
-
Halcyon
-
Mack
-
Maveric
-
Merb
-
Racktools::SimpleApplication
-
Ramaze
-
Ruby on Rails
-
Rum
-
Sinatra
-
Sin
-
Vintage
-
Waves
-
Wee
-
… and many others.
Available middleware¶ ↑
Between the server and the framework, Rack can be customized to your applications needs using middleware, for example:
-
Rack::URLMap, to route to multiple applications inside the same process.
-
Rack::CommonLogger, for creating Apache-style logfiles.
-
Rack::ShowException, for catching unhandled exceptions and presenting them in a nice and helpful way with clickable backtrace.
-
Rack::File, for serving static files.
-
…many others!
All these components use the same interface, which is described in detail in the Rack specification. These optional components can be used in any way you wish.
Convenience¶ ↑
If you want to develop outside of existing frameworks, implement your own ones, or develop middleware, Rack provides many helpers to create Rack applications quickly and without doing the same web stuff all over:
-
Rack::Request, which also provides query string parsing and multipart handling.
-
Rack::Response, for convenient generation of HTTP replies and cookie handling.
-
Rack::MockRequest and Rack::MockResponse for efficient and quick testing of Rack application without real HTTP round-trips.
rack-contrib¶ ↑
The plethora of useful middleware created the need for a project that collects fresh Rack middleware. rack-contrib includes a variety of add-on components for Rack and it is easy to contribute new modules.
rackup¶ ↑
rackup is a useful tool for running Rack applications, which uses the Rack::Builder DSL to configure middleware and build up applications easily.
rackup automatically figures out the environment it is run in, and runs your application as FastCGI, CGI, or standalone with Mongrel or WEBrick—all from the same configuration.
Quick start¶ ↑
Try the lobster!
Either with the embedded WEBrick starter:
ruby -Ilib lib/rack/lobster.rb
Or with rackup:
bin/rackup -Ilib example/lobster.ru
By default, the lobster is found at localhost:9292.
Installing with RubyGems¶ ↑
A Gem of Rack is available at rubygems.org. You can install it with:
gem install rack
I also provide a local mirror of the gems (and development snapshots) at my site:
gem install rack --source http://chneukirchen.org/releases/gems/
Running the tests¶ ↑
Testing Rack requires the bacon testing framework:
bundle install --without extra # to be able to run the fast tests
Or:
bundle install # this assumes that you have installed native extensions!
There are two rake-based test tasks:
rake test tests all the fast tests (no Handlers or Adapters) rake fulltest runs all the tests
The fast testsuite has no dependencies outside of the core Ruby installation and bacon.
To run the test suite completely, you need:
* fcgi * memcache-client * mongrel * thin
The full set of tests test FCGI access with lighttpd (on port 9203) so you will need lighttpd installed as well as the FCGI libraries and the fcgi gem:
Download and install lighttpd:
http://www.lighttpd.net/download
Installing the FCGI libraries:
curl -O http://www.fastcgi.com/dist/fcgi-2.4.0.tar.gz tar xzvf fcgi-2.4.0.tar.gz cd fcgi-2.4.0 ./configure --prefix=/usr/local make sudo make install cd ..
Installing the Ruby fcgi gem:
gem install fcgi
Furthermore, to test Memcache sessions, you need memcached (will be run on port 11211) and memcache-client installed.
Configuration¶ ↑
Several parameters can be modified on `Rack::Utils` to configure Rack behaviour.
e.g:
“`ruby Rack::Utils.key_space_limit = 128 “`
key_space_limit¶ ↑
The default number of bytes to allow a single parameter key to take up. This helps prevent a rogue client from flooding a Request.
Default to 65536 characters (4 kiB in worst case).
multipart_part_limit¶ ↑
The maximum number of parts a request can contain. Accepting too many part can lead to the server running out of file handles.
The default is `128`, which mean that a single request can't upload more than 128 files at once.
Set to `0` for not limit.
Can also be set via the `RACK_MULTIPART_PART_LIMIT` environment variable.
