Closing a Bet
Instructions
Send the amount to a new address we created for you.
Copy its private key (we don't know it, it's created in your browser)
Use this private key to sign the bet
Wait for the outcome of the event
If you won, you will get an unlock key from the oracle (in this case, us)
Use it to send the won amount back to you wallet
continue
Notes
The Bitcoins are locked in, for the duration of the bet.
... they are in no-one's wallet for that time.
... but they ARE in the blockchain.
Technically you OWN the full amount as soon as you receive the key
that the winner of the bet receives from the oracle.
The final transaction is only to make the Bitcoins easier to spend.
There is no way to unlock the money without at least one bidders
private keys.
Bidders can unlock the the money without the oracle at any time when
one gives his private key to the other (which was created for this one
bet only, so it can be shared without risk.)
We cannot unlock the bet and access the Bitcoins, unless we happen to
be both the oracle and the other party holding the other side of the
bet.
... which in the first prototype we ARE.
... while the aim is for the future to be NEITHER.
... which will then make the contracts completely decentralized.

Doctor reveals own payslip saying not all medics earn over £80,000
A doctor has hit out at a Question Time audience member who went viral by insisting he was not in the top 5% of earners – despite taking home £80,000.
Last week Rob Barber complained about Labour’s election policy of planning a 45p rate on earnings for those on the highest salaries and said all doctors earned more than him.
Now Dr Asif Munaf has shared his own salary to prove how ‘misinformed’ Mr Barber is.
Tweeting a picture of his £48,075 pay slip, he wrote: ‘This guy is terribly misinformed.
‘I spent 6 years at medschool and a further 7 years of specialist training and I get paid £48,000.
Advertisement Advertisement
‘He needs to #factscheck and use some of his £80,000 on a new shirt and trim.’
The clip of Mr Barber provoked widespread mockery after he jabbed his finger in the air and accused Labour of lying about their proposed tax hike only affecting the top 5% of earners.
The average UK salary is £29,000 and figures from the Office for National Statistics show that anyone earning more than £75,300 is in the top 5%.
But Mr Barber, who is believed to be an IT consultant, even suggested that his salary was not even in ‘the top 50% of earners.’
He said he did earn above the £80,000 threshold just like ‘every doctor, every accountant and every solicitor.’
But official figures suggest all those professions fall below £80,000 – with a doctor on £76,000.
Under Labour’s plan, Mr Barber would have to pay roughly an extra £50 for every £1,000 he earns over £80,000.

Basically Speaking
问题描述 :
The Really Neato Calculator Company, Inc. has recently hired your team to help design their Super Neato Model I calculator. As a computer scientist you suggested to the company that it would be neato if this new calculator could convert among number bases. The company thought this was a stupendous idea and has asked your team to come up with the prototype program for doing base conversion. The project manager of the Super Neato Model I calculator has informed you that the calculator will have the following neato features:
- It will have a 7-digital display.
- Its buttons will include the capital letters A through F in addition to the digits 0 through 9.
- It will support bases 2 through 16.
输入:
The input for your prototype program will consist of one base conversion per line. There will be three numbers per line. The first number will be the number in the base you are converting from. The second number is the base you are converting from. The third number is the base you are converting to. There will be one or more blanks surrounding (on either side of) the numbers. There are several lines of input and your program should continue to read until the end of file is reached.
输出:
The output will only be the converted number as it would appear on the display of the calculator. The number should be right justified in the 7-digit display. If the number is to large to appear on the display, then print “ERROR” (without the quotes) right justified in the display.

样例输出:
120 78 1765 7CA ERROR 11001 12D687 D071
解题代码:
import java.io.*; import java.util.*; import java.math.*; /** * * @author gongshaoqing */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here Scanner cin=new Scanner(System.in); String str; int inbas,oubas; while(cin.hasNext()) { str=cin.next(); inbas=cin.nextInt(); oubas=cin.nextInt(); BigInteger tmp=new BigInteger(str,inbas); str=tmp.toString(oubas); int len=str.length(); if(len>7)System.out.println(" ERROR"); else { str=str.toUpperCase(Locale.FRENCH); for(int i=0;i< 7-len;i++)System.out.print(" "); System.out.println(str); } } } }
(adsbygoogle = window.adsbygoogle || []).push({});
为什么不直接用STL排序呢？
这种题解就相当于直接贴代码了，，想看的是思路
写的很好~~
很给力啊，学习了
想问下computeLSPArray那里，if(len!=0) len=lps[len-1]是什么意思
scanner改用StreamTokenizer就不超时了
int L[m+1][n+1];这样定义出错，这个在gcc上可以编译通过 在VS上不行 应该改为new 或者vector
多谢提醒，是漏掉了
代码是给出了，但是解析的也太不清晰了吧！如 13 abejkcfghid jkebfghicda
第一步拆分为 三部分 (bejk, cfghi, d) * C(13,3)，为什么要这样拆分，原则是什么？
后面的掩码变量部分乍一看比较难理解，其实就是把32位按照一个整体来看待。
已经挂掉了，给个参考呗
很好。代码比书上的简练！
5.1处，反了；“上一个操作符的优先级比操作符ch的优先级大，或栈是空的就入栈。”如代码所述，应为“上一个操作符的优先级比操作符ch的优先级小，或栈是空的就入栈。”

Ukraine reports 11 enemy attacks in Donbas on Nov 19
There were no Ukrainian army casualties in the past day.
Russia's hybrid military forces on Tuesday mounted 11 attacks on Ukrainian positions in Donbas, eastern Ukraine.
"The armed forces of the Russian Federation and its mercenaries violated the ceasefire 11 times on November 19," the press center of Ukraine's Joint Forces Operation said in a Facebook update as of 07:00 Kyiv time on November 20, 2019.
The enemy opened fire from proscribed 82mm mortars, cannons installed on infantry fighting vehicles, grenade launchers of various systems, heavy machine guns, and small arms.
Under attack were Ukrainian positions near the villages of Vodiane, Starohnativka, Berezove, Hnutove, Krymske, Pivdenne, Zalizne, Luhanske, and Kindrashivska Nova.
"Since Wednesday midnight, Russia-led forces have attacked Ukrainian positions once near Berezove, using cannons installed on infantry fighting vehicles and heavy machine guns," the update said.

You can specify event handlers for region and region entry operations and for administrative events.
Implementing Cache Event Handlers
Depending on your installation and configuration, cache events can come from local operations, peers, servers, and remote sites. Event handlers register their interest in one or more events and are notified when the events occur.
Implementing an AsyncEventListener for Write-Behind Cache Event Handling
An
AsyncEventListener
asynchronously processes batches of events after they have been applied to a region. You can use anAsyncEventListener
implementation as a write-behind cache event handler to synchronize region updates with a database.How to Safely Modify the Cache from an Event Handler Callback
Event handlers are synchronous. If you need to change the cache or perform any other distributed operation from event handler callbacks, be careful to avoid activities that might block and affect your overall system performance.

TWILIGHT A film review by David N. Butterworth Copyright 1998 David N. Butterworth
**1/2 (out of ****)
After "Nobody's Fool" (the low-key, unsullied Paul Newman drama from 1994, not the Rosanna Arquette romantic "comedy" from 1986), I had high hopes for "Twilight," the latest film to team director Robert Benton with the man whose salad dressing has become a staple in my household.
Benton's "Nobody's Fool" was a thoughtful, satisfying, small-town drama which, along with Newman's typically fine work, was tempered by a couple of standout performances from the unlikely guises of Bruce Willis and Melanie Griffith. In his first film since then, Benton has assembled another first-rate cast headed up by Newman, Susan Sarandon, and Gene Hackman. But this small-time film noir, about an ex-cop turned private investigator, turned retiree, turned drunk, is remarkably--and disappointingly--ordinary.
You can't fault the performances though.
Sarandon and Hackman, who play fading movie stars Jack and Catherine Ames, are as solid and dependable as you'd expect from two performers with over fifty films each to their credit. Newman, too, is as every bit believable as Harry Ross, the ex-P.I. who lives with the Ames family and for whom he does occasional odd jobs. Jobs such as heading down to Puerta Vallarta to retrieve their teenage daughter Mel, played awkwardly and toplessly in the opening scenes by the up-and-coming Reese Witherspoon.
"Finding her was the easy part" Harry intones in the film's noirish voiceover and, as it turns out, he was right. This transaction sets up a boorish running gag about Harry being accidentally shot in the, ahem, inner thigh.

The film pours on the supporting cast like there's no tomorrow but I took great delight in seeing Liev Schreiber (from "The Daytrippers"), then M. Emmet Walsh, then Stockard Channing, then James Garner, then Giancarlo Esposito, then John Spencer, all popping up and contributing to the proceedings. It's the proceedings that just aren't all that special.
"Twilight" is a moody gumshoe tale that, although well acted, doesn't really take off. The plot's twists and turns, if you can call them that, aren't particularly riveting, and the substance of the piece, while tried and true, seems almost too tried and true. It's always fun watching Newman, Sarandon, and Hackman--even though they've all done better work elsewhere--as well as the supporting players but the writing (by Benton and Richard Russo) is, sadly, tepid and uninvolving.
There's not enough mystery, intrigue, or depth to make the film play like something from the pen of Dashiell Hammett. And there's not enough style or atmosphere for it to rank alongside such noir classics as "Chinatown," "The Maltese Falcon" or yes, even "L.A. Confidential" (nor do I believe it's even aiming that high).
No, "Twilight" has much smaller aspirations. Unfortunately small, as it does here, often amounts to less.

A filmmaker journalist was arrested for filming a pipeline protest in North Dakota. Deia Schlosberg was held in jail for 48 hours without access to her attorney, and now she's facing felony conspiracy charges. We need to get the government to drop these charges, which are an affront to the First Amendment.
Sign our petition to the U.S. Attorney to drop the charges against journalist Deia Schlosberg.
ADD YOUR NAMENative American tribal nations, farmers, and activists are protesting the Dakota Access pipeline for fracked oil, which would bring some of the dirtiest oil on the planet across five states.
Journalists and filmmakers have been at pipeline protests throughout North Dakota, documenting the bravery of activists who have been pepper sprayed and attacked with dogs for trying to protect native land and water sources.
But this week took a turn for the worse: a filmmaker at another solidarity protest in North Dakota against Tar Sands oil was arrested and charged with conspiracy for filming an action by activists to stop five pipelines from operating. Deia Schlosberg had her footage confiscated before being held in jail for two days and was not allowed to speak to an attorney. Now she's facing felony charges of conspiracy for filming the protest, and if Deia is convicted, she could face up to 45 years in prison.
We need to pressure the government to drop charges against Deia Schlosberg. Our best chance is to ask U.S. Attorney for North Dakota, Chris Myers, to drop the charges, and to make sure North Dakota Governor Jack Dalrymple and President Obama's Department of Justice also know Deia should not be charged.
Arresting journalists for documenting environmental actions is a dangerous precedent and an affront to the First Amendment.
Deia Schlosberg is an experienced and widely acclaimed filmmaker and journalist. She was the producer for Our Revolution Climate advisor Josh Fox's latest climate change documentary, How to Let Go of The World and Love All The Things Climate Can’t Change, and her work documenting environmental organizing is respected and critical.
 If filmmakers cannot film events as they're happening, especially protest events or events that the establishment and the police might consider criminal, our society will not be the same.
Pipelines that transport oil are some of the biggest threats to climate change. Pipelines can carry millions of gallons of dirty oil a day, and activists are doing all they can to stop these pipelines from being built or from operating.
People like Deia Schlosberg risk their safety to show these protests to the world, but now she's facing up to 45 years in prison for telling this story about threats to our climate.
Thank you for all you do to help stop the effects of climate change.

ANYWHERE BUT HERE (director:Wayne Wang; screenwriter: Alvin Sargent/based on the book by Mona Simpson; cinematographer: Roger Deakins; editor: Nicholas C. Smith; cast: Susan Sarandon (Adele August), Natalie Portman (Ann August), Eileen Ryan (Lillian), Ray Baker (Ted), John Diehl (Jimmy), Shawn Hatosy (Benny), Bonnie Bedelia (Carol), Michael Milhoan (Policeman), Hart Bochner (Dr. Josh Spritzer), Corbin Allred (Peter);Runtime: 113; Fox 2000 Pictures, 1999)
Reviewed by Dennis Schwartz
The title is taken from the writings of Ralph Waldo Emerson describing the life of a traveler as 'Anywhere but here.' There isn't one thing about this mother-daughter relationship melodrama that felt honest. It relies on a contrived minor character to tell both mother and daughter what was obvious to do in order to straighten out their dysfunctional lives, as for some reason they couldn't figure it out for themselves. If the film looks familiar, that is because "The Slums of Beverly Hills (98)" went over the same ground but was fortunate to be more comical and perceptive due to Alan Arkin and Natasha Lyonne performances, in which they were fortunate to have a much sharper script to work with. Alvin Sargent's script was weak and annoyingly claustral. Wayne Wang's ("The Joy Luck Club") inept direction made a weak script even weaker by his inability to tell the story unfolding without the voiceover relating what the action couldn't convey.
Pushy mother Adele August (Susan Sarandon) forces her 14-year-old daughter Ann (Natalie Portman) to leave a small Midwestern burg to go cross-country with her to Beverly Hills.   So it becomes a question of who knows best, as the ladies fight it out between them, until the predictable sweet ending comes in this yawner.
Adele's dream of greener pastures in Beverly Hills soon doesn't look that good, as she lands a job in a slum school, has her precious car scratched by the unruly kids, and settles into a job she hates in order to financially survive. Daughter pines for small town Wisconsin and her friends there. During one of many arguments with her free-spirited mom, they go for ice cream and while mother is being ticketed, she runs away, only to be chased down by friendly traffic cop (Michael Milhoan), who offers her wise counsel. With the cop's Zen wisdom passed onto the daughter, she will survive living in many different addresses in Beverly Hills until she reaches 17 and then she plans to get way from mom by using her good grades to go to Brown University instead of UCLA.
During their stay in Beverly Hills, she grows from feeling awkward in Beverly Hills High to immediately having many high school girlfriends and even a high school rich boy admirer-- a T.S. Eliot (Corbin Allred) reader. But the transition of her life into Beverly Hills had no feel of reality, as everything seemed staged and unemotional. When she learns her cousin Benny (Shawn Hatosy), who happens to be her best friend dies in a traffic accident back in Wisconsin, she returns for the funeral and in those reunion scenes it wasn't clearly shown why she wants to stay there, and for that matter, it was never made clear why the mother wants to leave so badly. The film is one big battle of wills between mother and daughter over their dreams. I guess what the filmmaker is trying to say, is that mom is a bad dreamer and the daughter is the observant one, able to recognize mother's faults when not in growing pains and in need of parenting herself.
Mother has a series of setbacks, like being dumped by her dream-boat dentist (Bochner) she met on the beach, and witnessing her daughter mimic her whiny optimistic sayings when trying out for an acting part. But mother learns that her daughter has grown-up and is independent and that she has to stop living her life through her. She learns this when the same wise cop who told Ann what to do, is about to ticket her and this time will remind the mother of the right thing to do. This of course results in the corny ending, showing that mom's heart was always in the right place, only she went about it in the wrong way. This was just one of those films where you want to be anywhere but in the theater where this film is showing.

question Java/C++/C# vs Node.js - 20170718
From comments in article The Shocking Secret About Static Types by Eric Elliott - 20160505
I’ve been seeing a lot of Java/C++/C# devs saying that you shouldn’t use Node.js to build a production app because it isn’t stable enough or maintainable enough partly due to it’s lack of static typing. They say Electron isn’t usable for desktop development for the same reasons.
[…]
Do you think Node.js is stable enough for creating commercial apps without needing tons of maintenance or should I use a language like Java instead?Companies who trust Node.js: Walmart, PayPal, Adobe, LinkedIn, IBM, Microsoft, Netflix, Uber, Medium, New York Times, etc…
PayPal made the switch from Java to Node in spite of the fact that PayPal’s entire engineering team was mostly familiar with Java, and not familiar with JavaScript.
Much of PayPal’s middle-tier infrastructure is now powered by Node and the team is now confident to push changes to production at a much higher pace than they ever did with Java.
You can see this for yourself looking at the vast improvement in all their apps since 2012. Learning to embrace change helped them stay relevant and restored their position as an innnovative company.
If the leading provider of global online payment solutions trusts Node in spite of the fact that the whole team was previously deeply invested in Java, and screwing up could impact the global payment economy that PayPal supports, that should tell you everything you need to know.
But in case it doesn’t, here’s my experience: I have a background in C++ and Java. I never built a large production C++ app that had an uptime you could measure in months or years. Because of the manual memory management and complicated (very imperative) type system, I was always fighting memory leaks or trying to escape strict typing with dynamic hacks. It felt too manual, rigid and restrictive.
My experience with Java was worse. Java made it hard to use simple functions as a basic building block. A lot of great work can be done by composing simple functions, but in Java, even the most trivial things require the overhead of class building and object instantiation, and even objects in Java are harder to compose than they need to be.
I kept my “Design Patterns” book on my desk when I was building apps with Java, constantly consulting it to figure out how to work around restrictions in the language.
Java was purpose built to abstract away from specific hardware platforms. It’s just a language, and nothing but classes and objects feel like first class citizens.
I thought all OO programming languages were like Java or C++ that until I started coding in JavaScript. JavaScript’s support for annotation-free types makes generic function programming default behavior. Support for first class functions and closures means powerful higher-order functions are at our fingertips whenever we need them. The syntax for those features is simple, easy to both write and read.
In other words, JavaScript can do a lot more with a lot less code, syntax noise, and cognitive overhead.
I have built many successful mission-critical apps in Node used by millions of people, with rock-solid performance and uptime, with development finishing twice as fast or even orders of magnitude faster than the legacy apps they replaced. I’ve been involved in PHP, Ruby on Rails, and Java ports to Node that have all been very successful.
When I code in Java or C++ now I feel like I’ve been stuck in a straight jacket.
Detractors will say “without static types you’ll have lots of bugs”, to which I say “type correctness does not guarantee program correctness.”
Whether or not you use static types, you should still use other bug prevention measures such as TDD (40% — 80% fewer bugs in production) code review (every hour in code review saves 33 hours in maintenance), and automated CI/CD.
It turns out, when you’re doing all that, very few type errors slip out into production anyway. Read “The Shocking Secret About Static Types”. Turns out that evidence finds static types have a very small impact on over-all bug density.
If you want reliable production apps, don’t use type system training wheels as your primary guarantee. Instead, invest in a good quality TDD + CI/CD process and code review.
Static types are cool, but anybody who tells you that you need them to build large, enterprise-scale apps is feeding you biassed opinion, ignorant of the facts, ignoring many thousands of mission critical enterprise apps that have been a huge success partially thanks to Node.
Node is such a solid choice these days it makes a great default workhorse for middle-tier web platform apps. And I haven’t even mentioned Universal JavaScript or Next.js yet. Google it. You’ll thank me.
From Java to Node - the PayPal story - 20160601
Node solved a problem for PayPal, it allowed them to do more, faster. Their existent model couldn’t catch up with existent trends, starting with the introduction of full stack developers. The biggest problem at PayPal was the barrier between the server and the browser. Node was a great solution from the beginning because it allowed them to write applications in JavaScript both for the browser and the server.
This app was built in Kraken.js on express, using the templating engine Dust and the Java software used an internal framework that was mostly based on Spring. The first production tests showed great promise and also brought peace of mind, as the node app responded to requests about 45% faster than the Java app, a very visible difference for the user.

What you should know to really understand the Node.js Event Loop - 20170720
Java EE threads v/s Node.js - which is better for concurrent data processing operations - 20130609
The most important differences between NodeJS and Java are the concurrency and I/O models. Java uses multithreaded synchronous I/O while NodeJS uses single threaded asynchronous I/O.
Node.js — How is it different? - Siddhartha Chowdhury - 20180206
When does Node.js fails ?
Node’s underlying architecture implementation fails when some CPU intensive work is involved.
By CPU intensive I mean works like Image processing, audio encoding, media conversions, etc.
All these jobs involves huge CPU computations and almost no I/O. Hence when the event (which involves as such work) handler is fired, it keeps the the event loop busy until the time the CPU processing is finished, it halts all other events in the process.
This case is where C++, Java, Python and all other excels coz their underlying architecture makes use of multiple threads to handle concurrency at their core.

detailled event loop explanation
V8 Engine : Run time Environment
It’s an open sourceJIT(Just In Time) compiler written in C++.
V8 compiles Javascript directly into assembly level code.
- Compiler : dissects the JS code
- Optimizer : Optimizer called crankshaft create abstract syntax tree(AST) which further converts to SSA : static single assignment and gets optimized
- Garbage Collector : V8 divides the memory into 2 spaces Old spaces and new spaces both belongs to heap memory and keeps track of JS objects, any new objects is stored in new space. When new space is fully occupied V8’s garbage collector removes dead objects from new space and puts into old space. Gabage collector play vial role in keeping NodeJs lightweight.

Phases Overview
- timers: this phase executes callbacks scheduled by
setTimeout()
andsetInterval()
. - I/O callbacks: executes almost all callbacks with the exception of close callbacks, the ones scheduled by timers, and
setImmediate()
. - idle, prepare: only used internally.
- poll: retrieve new I/O events; node will block here when appropriate.
- check:
setImmediate()
callbacks are invoked here. - close callbacks: e.g.
socket.on('close', ...)
.
Between each run of the event loop, Node.js checks if it is waiting for any asynchronous I/O or timers and shuts down cleanly if there are not any.

Nest provides a variety of transporters out-of-the-box, as well as an API allowing developers to build new custom transport strategies. Transporters enable you to connect components over a network using a pluggable communications layer and a very simple application-level message protocol (read full article).
Hint Building a microservice with Nest does not necessarily mean you must use the@nestjs/microservices
package. For example, if you want to communicate with external services (let's say other microservices written in different languages), you may not need all the features provided by@nestjs/microservice
library. In fact, if you don't need decorators (@EventPattern
or@MessagePattern
) that let you declaratively define subscribers, running a Standalone Application and manually maintaining connection/subscribing to channels should be enough for most use-cases and will provide you with more flexibility.
With a custom transporter, you can integrate any messaging system/protocol (including Google Cloud Pub/Sub, Amazon Kinesis, and others) or extend the existing one, adding extra features on top (for example, QoS for MQTT).
Hint To better understand how Nest microservices work and how you can extend the capabilities of existing transporters, we recommend reading the NestJS Microservices in Action and Advanced NestJS Microservices article series.
First, let's define a class representing our custom transporter.
import { CustomTransportStrategy, Server } from '@nestjs/microservices';
class GoogleCloudPubSubServer
extends Server
implements CustomTransportStrategy {
/**
* This method is triggered when you run "app.listen()".
*/
listen(callback: () => void) {
callback();
}
/**
* This method is triggered on application shutdown.
*/
close() {}
}
Warning Please, note we won't be implementing a fully-featured Google Cloud Pub/Sub server in this chapter as this would require diving into transporter specific technical details.
In our example above, we declared the GoogleCloudPubSubServer
class and provided listen()
and close()
methods enforced by the CustomTransportStrategy
interface.
Also, our class extends the Server
class imported from the @nestjs/microservices
package that provides a few useful methods, for example, methods used by Nest runtime to register message handlers. Alternatively, in case you want to extend the capabilities of an existing transport strategy, you could extend the corresponding server class, for example, ServerRedis
.
Conventionally, we added the "Server"
suffix to our class as it will be responsible for subscribing to messages/events (and responding to them, if necessary).
With this in place, we can now use our custom strategy instead of using a built-in transporter, as follows:
const app = await NestFactory.createMicroservice<MicroserviceOptions>(
AppModule,
{
strategy: new GoogleCloudPubSubServer(),
},
);
Basically, instead of passing the normal transporter options object with transport
and options
properties, we pass a single property, strategy
, whose value is an instance of our custom transporter class.
Back to our GoogleCloudPubSubServer
class, in a real-world application, we would be establishing a connection to our message broker/external service and registering subscribers/listening to specific channels in listen()
method (and then removing subscriptions & closing the connection in the close()
teardown method),
but since this requires a good understanding of how Nest microservices communicate with each other, we recommend reading this article series.
In this chapter instead, we'll focus on the capabilities the Server
class provides and how you can leverage them to build custom strategies.
For example, let's say that somewhere in our application, the following message handler is defined:
@MessagePattern('echo')
echo(@Payload() data: object) {
return data;
}
This message handler will be automatically registered by Nest runtime. With Server
class, you can see what message patterns have been registered and also, access and execute the actual methods that were assigned to them.
To test this out, let's add a simple console.log
inside listen()
method before callback
function is called:
listen(callback: () => void) {
console.log(this.messageHandlers);
callback();
}
After your application restarts, you'll see the following log in your terminal:
Map { 'echo' => [AsyncFunction] { isEventHandler: false } }
Hint If we used the@EventPattern
decorator, you would see the same output, but with theisEventHandler
property set totrue
.
As you can see, the messageHandlers
property is a Map
collection of all message (and event) handlers, in which patterns are being used as keys.
Now, you can use a key (for example, "echo"
) to receive a reference to the message handler:
async listen(callback: () => void) {
const echoHandler = this.messageHandlers.get('echo');
console.log(await echoHandler('Hello world!'));
callback();
}
Once we execute the echoHandler
passing an arbitrary string as an argument ("Hello world!"
here), we should see it in the console:
Hello world!
Which means that our method handler was properly executed.
As we mentioned in the first section, you don't necessarily need to use the @nestjs/microservices
package to create microservices, but if you decide to do so and you need to integrate a custom strategy, you will need to provide a "client" class too.
Hint Again, implementing a fully-featured client class compatible with all @nestjs/microservices
features (e.g., streaming) requires a good understading of communication techniques used by the framework. To learn more, check out this article.
To communicate with an external service/emit & publish messages (or events) you can either use a library-specific SDK package, or implement a custom client class that extends the ClientProxy
, as follows:
import { ClientProxy, ReadPacket, WritePacket } from '@nestjs/microservices';
class GoogleCloudPubSubClient extends ClientProxy {
async connect(): Promise<any> {}
async close() {}
async dispatchEvent(packet: ReadPacket<any>): Promise<any> {}
publish(
packet: ReadPacket<any>,
callback: (packet: WritePacket<any>) => void,
): Function {}
}
Warning Please, note we won't be implementing a fully-featured Google Cloud Pub/Sub client in this chapter as this would require diving into transporter specific technical details.
As you can see, ClientProxy
class requires us to provide several methods for establishing & closing the connection and publishing messages (publish
) and events (dispatchEvent
).
Note, if you don't need a request-response communication style support, you can leave the publish()
method empty. Likewise, if you don't need to support event-based communication, skip the dispatchEvent()
method.
To observe what and when those methods are executed, let's add multiple console.log
calls, as follows:
class GoogleCloudPubSubClient extends ClientProxy {
async connect(): Promise<any> {
console.log('connect');
}
async close() {
console.log('close');
}
async dispatchEvent(packet: ReadPacket<any>): Promise<any> {
return console.log('event to dispatch: ', packet);
}
publish(
packet: ReadPacket<any>,
callback: (packet: WritePacket<any>) => void,
): Function {
console.log('message:', packet);
// In a real-world application, the "callback" function should be executed
// with payload sent back from the responder. Here, we'll simply simulate (5 seconds delay)
// that response came through by passing the same "data" as we've originally passed in.
setTimeout(() => callback({ response: packet.data }), 5000);
return () => console.log('teardown');
}
}
With this in place, let's create an instance of GoogleCloudPubSubClient
class and run the send()
method (which you might have seen in earlier chapters), subscribing to the returned observable stream.
const googlePubSubClient = new GoogleCloudPubSubClient();
googlePubSubClient
.send('pattern', 'Hello world!')
.subscribe((response) => console.log(response));
Now, you should see the following output in your terminal:
connect
message: { pattern: 'pattern', data: 'Hello world!' }
Hello world! // <-- after 5 seconds
To test if our "teardown" method (which our publish()
method returns) is properly executed, let's apply a timeout operator to our stream, setting it to 2 seconds to make sure it throws earlier then our setTimeout
calls the callback
function.
const googlePubSubClient = new GoogleCloudPubSubClient();
googlePubSubClient
.send('pattern', 'Hello world!')
.pipe(timeout(2000))
.subscribe(
(response) => console.log(response),
(error) => console.error(error.message),
);
Hint Thetimeout
operator is imported from therxjs/operators
package.
With timeout
operator applied, your terminal output should look as follows:
connect
message: { pattern: 'pattern', data: 'Hello world!' }
teardown // <-- teardown
Timeout has occurred
To dispatch an event (instead of sending a message), use the emit()
method:
googlePubSubClient.emit('event', 'Hello world!');
And that's what you should see in the console:
connect
event to dispatch: { pattern: 'event', data: 'Hello world!' }
If you need to add some custom logic around the serialization of responses on the client side, you can use a custom class that extends the ClientProxy
class or one of its child classes. For modifying successful requests you can override the serializeResponse
method, and for modifying any errors that go through this client you can override the serializeError
method. To make use of this custom class, you can pass the class itself to the ClientsModule.register()
method using the customClass
property. Below is an example of a custom ClientProxy
that serializes each error into an RpcException
.
import { ClientTcp, RpcException } from '@nestjs/microservices';
class ErrorHandlingProxy extends ClientTCP {
serializeError(err: Error) {
return new RpcException(err);
}
}
and then use it in the ClientsModule
like so:
@Module({
imports: [
ClientsModule.register({
name: 'CustomProxy',
customClass: ErrorHandlingProxy,
}),
]
})
export class AppModule
hint This is the class itself being passed tocustomClass
, not an instance of the class. Nest will create the instance under the hood for you, and will pass any options given to theoptions
property to the newClientProxy
.


The Search
The search for the flight was one of the largest and most expensive in aviation history
International Participation
The international search for the plane involved 26 countries equipped with boats, planes, submarines and more.
The search effort took place in multiple areas. The inital areas of search were along the South China Sea. The area was expanded to cover the Strait of Malacca after the Malaysian Military revealed more information.
However, days after the disappearance, more information came out about the flight. The search areas were adjusted again using satellite handshakes. The new search areas were very remote, sometimes taking days just to reach there.
The Debris
The search covered almost three-million square miles and, yet no sign of wreckage was ever found... until years later.
In 2015, beach cleaners in Réunion Island stumbled upon what turned out to be a right wing flaperon. The flaperon was examined and was later confirmed to belong to MH370.
In the following months, more debris was discovered. You can see them here

To approach our current EnterpriseServices/COM+ discussion in a somewhat different director, let me ask a question that's been nagging me for a while now. Perhaps someone knows the answer or can point me towards some documentation (online, book, whatever).
What exactly is the relation, and the interactions between, unmanaged and managed contexts? Now, I do know the basics, but not much more. Managed contexts are very undocumented, and I'm not sure I know much about them (I'd particularly like to understand when and why they are created by the runtime), but how they relate to unmanaged contexts is even more misterious (to me, at least).
So, for example, as I understand it, a ContextBoundObject-derived object will be bound to a managed context, while a ServicedComponent-derived object is furthermore constrained to be bound to an unmanaged COM+ context. However, that's doesn't say all that much. For example, is there always a managed context for every unmanaged context? Or can an unmanaged context contain multiple managed contexts? Or are managed ContextBoundObject-derived objects context-agile with respect to unmanaged contexts?
As you see, this is a topic I find confusing, and would love to understand it in greater detail...

--- layout: post title: CPU High Performance INNODB MYSQL author: Galuh D Wijatmiko categories: [SecurityTunningAndHardening,Databases] tags: [Service,mysql] ---
I learned something amazing about MySQL. If you allocate a single monolithic InnoDB Buffer Pool that is bigger that Total Installed Divided By Number of Physical CPUs, your will incite the OS to regular intervals memory swapping due to a full InnoDB Buffer Pool. MySQL 5.5’s option known as innodb_buffer_pool_instances
can be used to split up the buffer pool. Yesterday, I properly
implemented this for the client I mentioned in my answer last year. I
still have 162GB for the client’s Buffer Pool. I have set the server’s
innodb_buffer_pool_instances option to 2 because each DB Server is dual
hexacore. I was thinking of setting it to 12 but then a colleague showed
me a blog from Jeremy Cole on MySQL and Swappiness. After reading it, I put it into practice immediately for my client. I ran this command
numactl --hardware
I saw a mapping of 192GB of server RAM as 96GB to each physical core.
Therefore, I set the innodb_buffer_pool_instances to 2. Things are
looking good right now. I will update my answer to see how this affects
memory swapping for the next 2 montns.
on my.cnf
innodb_buffer_pool_size = ???M
innodb_buffer_pool_instances = ??(default:1.2,4,8)

Recommended range: 60~80%
Expression: Innodb_buffer_pool_reads / Innodb_buffer_pool_read_requests
Meaning: Read requests that had to hit disk
Recommended range: 0-2%
What to do if out of range: Increase innodb_buffer_pool_size if you have enough RAM.
Expression: Innodb_pages_read / Innodb_buffer_pool_read_requests

What to do if out of range: First be sure innodb_buffer_pool_size is set reasonably; if still trouble, decrease innodb_max_dirty_pages_pct
OBSERVATION #1
When committing to use InnoDB, you also need to commit to tuning for multiple cores.
OBSERVATION #2
I see you have innodb_thread_concurrency = 8
. If you set innodb_thread_concurrency
to 0 (which is the default), you will have infinite concurrency. That
let’s the InnoDB storage engine decide how to many threads it feels it
needs and can handle.
OBSERVATION #3
Your DB Server has 12GB of RAM. Your InnoDB Buffer Pool is bigger
than half the RAM. You need to partition the Buffer Pool by setting innodb_buffer_pool_instances to 2. In conjunction with this, you need to run numactl --interleave=all
(Not applicable to VMs).
OBSERVATION #4
I see you have innodb_file_format = Barracuda
. I wish you can go back to innodb_file_format = Antelope
.
Why go back to uncompressed? It tends to bloat the InnoDB Buffer Pool
because compressed and uncompressed data and index pages coexist in the
Buffer Pool. I just wrote about this : See my post innodb_file_format Barracuda

.ibdata1
. You can spread out disk I/O for InnoDB by separating InnoDB tables from ibdata1. See my StackOverflow post Howto: Clean a mysql InnoDB storage engine? on how to do this and to fully defragment ibdata1

NPSAppManaged provides a framework to start and end your application and to manage the display of the various Forms that you have created, in a way that should not create recursion depth problems.
Unless you have exceptionally good reasons to do otherwise, NPSAppManaged is almost certainly the best way to manage your application.
Unlike the plain NPSApp class, you do not need to write your own main loop - NPSAppManaged will manage the display of each Form of your application. Set up your form objects and simply call the .run() method of your NPSAppManaged instance.
There are three methods for registering a Form object with an NPSAppManaged instance:
This version creates a new form and registers it with the NPSAppManaged instance. It returns a weakref.proxy to the form object. id should be a string that uniquely identifies the Form. FormClass should be the class of form to create. Any additional arguments will be passed to the Form’s constructor. Use this version if you are not storing a separate reference to your form elsewhere.
This version registers a class of form rather than an instance. A new instance will be created every time it is edited. Additional arguements will be passed to the form’s constructor every time it is created.
id should be a string that uniquely identifies the form. fm should be a Form object. Note that this version only stores a weakref.proxy inside NPSAppManaged - in contrast to the .addForm version.
All Forms registered with an NPSAppManaged instance can access the controlling application as self.parentApp.
If for any reason you need to remove a Form, you can do with the .removeForm(*id*) method.
Start an NPSAppManaged application mainloop. This method will activate the default form, which should have been given an id of “MAIN”.
If for any reason you need to change the name of the default form, you can change it here.
Once an application is running, the following methods control which form is presented to the user.
Set the form to be displayed when the current one exits.
Set the form to be displayed when the current one exits to the previous one in the history
Immediately switch to the named form, bypassing any exit logic of the current form.
Immediately switch to the previous form in the history.
Once all of your forms are ready and registered with an NPSAppManaged instance, you should call .run()
This method will activate the default form, which should have been given an id of “MAIN”. You can change this default by changing the class/instance variable .STARTING_FORM.
Thereafter, the next form to be displayed will be the one specified by the instance variable NEXT_ACTIVE_FORM. Whenever a Form edit loop exits, the Form specified here will be activated. If NEXT_ACTIVE_FORM is None, the main loop will exit. NEXT_ACTIVE_FORM should be set by calling the application’s setNextForm(formid) method. This documentation used to suggest that you set the attribute directly. While there are no immediate plans to deprecate this attribute, setting it directly should be avoided.
There are three mechanisms that Forms should use to control NEXT_ACTIVE_FORM.
All Forms registered with an NPSAppManaged which do not have the special method .activate() will have their method .afterEditing called, if they have it. Logic to determine which the NEXT_ACTIVE_FORM should be should go here. NEXT_ACTIVE_FORM should be set by calling the application’s setNextForm(formid) method. If you are expecting your users to select an ok or cancel button, this is the preferred way to switch screens.
The application method switchForm(formid) causes the application to immediately stop editing the current form and switch to the one specified. Depending on the type of Form, the logic associated with them may be bypassed too.
Forms registered with an NPSAppManaged may be given an .activate() method, which NPSAppManaged will call instead of the usual .edit() method. This can contain additional logic. This is NOT the preferred method, but may allow greater flexibility. Note that in this case, the usual .edit() method will not be called, unless you call it explicitly. For example, an .activate() method might look like this:
def activate(self):
self.edit()
self.parentApp.setNextForm(None)
which would cause the mainloop to exit after the Form was complete.
The following methods may be usefully overridden by subclassing NPSAppManaged. By default they do nothing.
Called between each screen while the application is running. Not called before the first screen.
Override this method to perform any initialisation. If you wish, you can set up your application’s Forms here.
Override this method to perform any cleanup when application is exiting without error.
If this is set, new forms will be created with keypress_timeout set to this, provided they know what application they belong to - i.e. they have been passed parentApp= at creation time. If you are using NPSAppManaged, this will happen automatically.
Applications can also have a while_waiting method. You can define and override this at will, and it will be called while the application is waiting for user input (see the while_waiting method on forms). The
This method is for internal use by npyscreen.
Immediately stop editing the current form and switch to the specified form.
Immediately switch to the previous form in the history.
Forget the previous forms visted.
Get a list of the Forms visited
Forms called by NPSAppManaged can be given the methods
called before the edit loop of the form is called
called when the form is exited
The presence of this method entirely overrides the existing .beforeEditing .edit and afterEditing methods.
To use NPSApp subclass it and provide your own .main() definition. When you are ready to run the application call .run() and your mainloop will be executed.
While it provides maximum flexibility, NPSApp is in almost every other way inferior to NPSAppManaged. Do not use it for new projects, and reguard it as an internal base class only.


"Death from above!"

Middle Line DPS: Can activate a number of unique Offensive and Defensive Abilities, and his Ultimate can absorb the Damage that would have been taken by teammates
| Health | 77 | Health | 138 | |
| Physical Attack | 6 | Physical Attack | 10.8 | |
| Magic Attack | 7 | Magic Attack | 12.6 | |

None
Avior comes to the aid of his teammates, absorbing most of the Damage that would have been taken by his allies for a short period, and deflecting some of the Damage back at the enemy when the Ultimate ends. While using this Ultimate, Avior has all 4 layers of Dragonscale Armor (4th ability), and is immune to Control abilities. If Avior is hit by what would be a lethal attack while using this Ultimate, the Damage will be blocked and deflected back at an enemy unit immediately
Avior summons a dragon ally that hovers over the enemy back line, launching attacks which deal Magic Damage and interrupting enemy abilities. The summoned dragon only exists for a short time before exploding, which also deals Magic Damage and Stuns enemies in the immediate vicinity
Avior feasts on the Health lost by enemies and allies alike, strengthening his Basic Attack. This ability has three tiers; a new tier is activated every time any unit takes a significant amount of Damage. The 1st Tier turns his Basic Attacks from Physical to Magic. The 2nd Tier gives his Basic Attacks additional Damage and increases his Attack Speed. The 3rd Tier allows his Basic Attack to fire an additional projectile
Avior relies on his tough dragon-scales to protect him, giving him increased Physical and Magic Armor. By default, he has one layer of dragon-scales which cannot be destroyed, and he will grow up to 3 additional layers over time. Each layer can withstand at least 4 hits before breaking (the layers also heal themselves over time)
Avior constantly monitors the battlefield for an enemy with low Health. When he’s found his target, he grasps their soul, causing them to lose Health-over-Time. This ability also weakens the effect of Healing spells cast upon the enemy hero

Assemblathon 1: A competitive assessment of de novo short read assembly methods
Abstract
Low cost short read sequencing technology has revolutionised genomics, though it is only just becoming practical for the high quality de novo assembly of a novel large genome. We describe the Assemblathon 1 competition, which aimed to comprehensively assess the state of the art in de novo assembly methods when applied to current sequencing technologies. In a collaborative effort teams were asked to assemble a simulated Illumina HiSeq dataset of an unknown, simulated diploid genome. A total of 41 assemblies from 17 different groups were received. Novel haplotype aware assessments of coverage, contiguity, structure, base calling and copy number were made. We establish that within this benchmark (1) it is possible to assemble the genome to a high level of coverage and accuracy, and that (2) large differences exist between the assemblies, suggesting room for further improvements in current methods.


This workflow allows you use Alfred to send a phone number to your iPhone, which your phone will then dial automatically when you open the notification. You will need to have Prowl installed on your iPhone to receive the notifications. You can send a number from either:
First things first: you need an API key for Prowl - a unique string of digits that allows Alfred to connect to the Prowl service on your behalf. Get that here, or the workflow will direct you to the site when you first use it.
The workflow should prompt you for your API key the first time you run it. If you need to change it at some point, use the keyword dial setup.
Enter it in, and you’re good to go.
You can now manually send a phone number. Try dial phonenumber in Alfred and you should receive the Prowl alert on your iPhone within seconds. (Alfred will show you a notification confirming the success or failure of the phone number transmission.)
To send selected text, invoke the workflow via a hotkey. You’ll need to configure this hotkey in the Workflows pane of Alfred’s preferences:
To send the number of a contact from your Address Book, you’ll need to enable a “custom action” in Alfred’s Contact preferences.
For the contact field “Phone”, choose the action “Dial with iPhone (via Prowl)”. And that’s it. Now, when you display a Contact in Alfred, just select their phone number to dial it from your iPhone!
I hope this workflow is useful to you. Please leave feedback/bug reports/suggestion in the comments on the workflow’s homepage, the Alfred forum or via Twitter (@CarlosNZ).

Notes:
Spelling of "FORECERENEW" is incorrect. It should be "FORCERENEW"


WWII soldier laid to rest in Boston after remains identified
by EndPlayNEEDHAM, Mass. (AP) - A Massachusetts solider killed in World War II has been laid to rest after his remains were recently identified.
WCVB-TV reports a memorial service was held Saturday at St. Joseph church in Needham, Massachusetts for U.S. Army 1st Lt. Joseph Edward Finneran.
He was then buried with full military honors in Mount Benedict Cemetery in Boston's West Roxbury neighborhood, alongside his mother.
The 22-year-old was shot down north of Bucharest, Romania on Aug. 1, 1943 during a bombing mission. He was posthumously awarded the Purple Heart and other military honors.
Finneran's unidentified remains had been kept inside a military cemetery in Belgium for 70 years along with other Americans killed during "Operation Tidal Wave."
The Pentagon last month announced it had accounted for Finneran using anthropological and DNA analysis.

Deuteronomy 2:15
For indeed the hand of the LORD was against them, to destroy them from among the host, until they were consumed.


Nyzo version 501 (commit on GitHub) corrects blacklist logic issues in the MeshListener class.
This version affects the verifier only. The sentinel does not use the MeshListener class.
Two separate logic errors in the MeshListener class were causing incorrect accumulations of concurrent-connection counts, resulting in erroneous and recurrent blacklisting of many IP addresses. While some protection mechanisms are mitigating this problem, the issue is serious, and all verifiers should update as soon as possible.
The first, more serious, logic error was in the handling of the merge() call on the connectionsPerIp map. This call was used to obtain AtomicInteger objects, and these objects were incremented and decremented directly. However, as each merge() call produced a new AtomicInteger object, any call to merge() that was followed by another call to merge() for the same IP before the corresponding decrement call would result in a permanent increase in the count for that IP address. Therefore, instead of tracking present concurrent connections per IP, the map functioned more as a historical aggregator of concurrent connections per IP.
The map is still used, but AtomicIntegers have been replaced with Integers, as atomic increments and decrements of the individual objects have been replaced with the atomic merge operation. The merge function has been rewritten to use Integer objects.
The map type arguments have been updated appropriately in the connectionsPerIp declaration and processSocket() signature.
All increment operations have been replaced with merge() calls with a value of 1, and all decrement operations have been replaced with merge() calls with a value of -1.
The other issue, while less serious on its own, eliminated a protection that would have prevented the first issue from inappropriately blacklisting verifiers. The first issue caused errors to accumulate in the connectionsPerIp map. The second issue prevented the connectionsPerIp map from being periodically cleared. While this periodic clearing of the map was only intended as a memory-conservation measure, it would have also erased the accumulated errors frequently enough that they would likely have never produced any symptoms.
The map was never cleared because the increment of activeReadThreads was omitted. Therefore, the value of activeReadThreads was always negative, never the value of exactly 0 required to trigger clearing of the map.
Finally, decrementing of the number of connections per IP has been moved just before clearing of the map instead of just after. If the decrement were performed just after clearing of the map, the value would incorrectly be -1 for the affected IP. This is a minor issue that would only increase the practical limit by 1 for that IP, but it is incorrect behavior.
In an unrelated change, the mask for string length has been corrected in the Message class. This corrects some issues with reading debug responses with long lines.

Features of java.io.File
in the Java 2 Platform
The File class is a
true abstract representation of file and directory pathnames. This
allows the File class to better support non-UNIX platforms such as
Windows, which has a rich pathname syntax involving drive letters,
UNC share names, and multiple separator characters. The
specification of class File prior to the Java Platform could not handle these cases
because it was written in terms of simple string operations.
The following features were introduced in the File
class in Java SE 1.2:


Sting pays tribute to Juice WRLD
Rapper died Sunday at age of 21
by Toyin Owoseje, CNN(CNN) - Sting says that Juice WRLD's hit single "Lucid Dreams" is his all-time favorite reworking of "Shape of my Heart," following the emo rapper's death.
The Grammy-winning singer was among a long list of stars who paid tribute to Juice after his death Sunday at the age of 21.
Sting, 68, described the Chicago native as a "unique and precious talent" and offered his sincere condolences to his family.
"This is such a tragic loss for the world of music, a young life with so much potential and a unique and precious talent," the British singer told CNN in a statement.
Although Sting never had the opportunity to work with Juice, "Lucid Dreams" contains a reworked sample from Sting's classic 1993 track "Shape of My Heart."
Following its release in May 2018, Sting returned to the top of Billboard's Hot R&B/Hip-Hop Songs chart as a songwriter.
"'Lucid Dreams' was my favorite of all the many interpolations of 'Shape of my Heart,' it will resonate for many years to come," Sting said of the melancholic track which reached No. 2 on the US Billboard singles chart.
Earlier this year, Sting confirmed he had given Juice WRLD his blessing to sample "Shape of My Heart."
"I'm totally open to see what people do with that ('Shape of My Heart') as a basis," he told SiriusXM hosts Mark Goodman and Jim Shearer during an appearance on their radio show in May, adding: "It's exciting to hear that."
Juice, real name Jarad Anthony Higgins, died in a Chicago hospital after suffering a medical emergency just after landing at Chicago's Midway International Airport.
"There were no signs of foul play and all individuals aboard the aircraft are cooperating with CPD and have given all of their information," Chicago police spokesman Anthony Guglielmi said in an email to CNN.

Problem Solving and Pseudocode
During Sprint 4 I was stuck on one of the Kata challenges, the one where you had to manipulate javascript objects, which in grammar sense is giving each words names like nouns, verbs, adjectives. I was stuck on the same problem for a long time.
I googled the same issue and couldn't find any close answers. So I had some of the peers in my cohort to help me on this issue, and the problem turned out to be not the object in this case names of each word in grammar, but the commas and organizing the words itself. It helped me solve the problem I was stuck on as well as remind me of how important it is to put commas and brackets in the right place, even when you are writing a sentence and also when you are writing a code.
Throughout the sprints I have used pseudocode which enabled me to navigate through different codes as it worked well as a sticky note, read what the error messages said, console logged in order to check if the code worked, googled what new methods could be used in some situations, asked peers and coaches to help and writing the reflections has also made me look back on what I have studied, what I have learned from it, what I can improve. In most cases, while I was writing reflections I realised that I still have missed out some details from the sprints and makes me go back to the part I missed and study it again.
From trying variety of problem solving methods I am confident in using the sources in order to solve the problem.
