General schema.
In our real life, we use boxes for storing, transporting or sorting all of our things.
In programming, we use variables to store, transport and sort things. We can do the same things like in real life with variables: storing, transporting, sorting.
Let’s look at a schema, which shows how to declare and initialize variables.
[type] [name] [=] [value];
, where
type – It is a type of variable, like you use a jar for keeping liquid and you can’t use a paper box for it. A special type of container
name – it is identification of out variable, like you are human and you have a name. All variables must have names.
= - it is a symbol, which is used for assigning the value to our variables.
value – it is our data, information.
Java is stronged type program language. It means that you must declare variable with particular type and store the same value with such type.
Now here is a simple:
public class Main {
public static void main(String[] args) {
int age = 25;
char sex = 'm';
boolean paid = false;
System.out.println("Age : " + age);
System.out.println("Sex : " + sex);
System.out.println("Paid : " + paid);
}
}
Here I created three variables: age, sex, paid. Each variables have a type.
A variable can’t keep the value with other types, which it was created.
The follow code is wrong: int age = ‘m’;
Because a variable age has int type, and we can keep only numbers in this variable.
primitive and reference
Java has two groups of variables types: primitive and reference.
In this lesson I am going to talk only about primitive types.
Java has 8 primitive types.
We can split it to 4 groups.
- boolean, the type whose values are either true or false
- char, the character type whose values are 16-bit Unicode characters
- the integral types: byte, short, int, long
- the floating-point types: float, double
Arithmetical operators.
We can use all arithmetical operators with primitive types.
Addition.
int first = 10;
int second = 15;
int result = first + second;
System.out.println("Result : " + result);
Here you can see how we calculate the value and assign in directly to new variables
int result = first + second;
Subtraction.
int first = 10;
int second = 15;
int result = first - second;
System.out.println("Result : " + result);
Divide
int first = 4;
int second = 2;
int result = first / second;
System.out.println("Result : " + result);
Multiplication.
int first = 10;
int second = 15;
int result = first * second;
System.out.println("Result : " + result);
Reassign the values.
One interesting thing about variables is reassigning. We don’t have such operation in mathematic.
Let’s consider that I need to increment the value on one.
I can do in Java like this.
int count = 0;
count = count + 1;
System.out.println("Count : " + count);
count = count + 1;
Java reads the value from count variable. Then it adds an one. Then it writes the value to variables count.
Java has simplified form of such expression:
count += 10;
it is the same like count = count + 10;
If we talk only increment or decrement on one, you can use such simplified form.
count++; count--;
Local-Variable Type Inference
Java 10 introduce a new simplified form of declare variable type.
Let’s consider the follow code;
var price = 10.99;
System.out.println("Price : " + price);
Java extracts the type variable from value.
You can’t use such form if you don’t assign value.
Wrong!
var price;
price = 10.99;
Let’s rewrite the first sample with summation.
var first = 10;
var second = 15;
var result = first + second;
System.out.println("Result : " + result);
I will tell about this feature more in the next lessons.
Exercises.
Write code which will calculate the average salary in years and print it to the console.
Create the variables and give the name of each month.
Calculate the average amount.
Print it to the console.
Input: 23, 43, 50, 52, 40, 12, 40, 50, 40, 50.
2. Implement mathematical function.
F(x) = a * x + c;
Calculate the value of F(x) for x = 4, when a = 3 and c equals 2;
Result should be printed in console.

Brief Introuduction
We are developing Artificial Perception Systems, especially the visual perception devices for some embedded application scenario to enhance environmental awareness of organism and robots, as well as IOT devices for environment monitoring.
iEyes (intelligent Eyes) is our FPGA-based vision processing platform, on which some system architectures and algorithms would be evaluated, such as feature extractions with both conventional and prevailing machine learning methods. More, the target application of iEyes platform is location and navigation for various robots, currently.
For future systems of ISP and machine learning with even higher energy efficiency requirements, where the current FPGA/ASIC implementations could not achieve, we are developing Approximate Computing architecture to balance the energy efficiency and computing quality. We also present the Physical Computing architecture for such perception systems, which could extract useful information directly in the analog sensing signal and achieve 3~6 orders of energy-efficiency improvements.
Novel devices are also adopted. We are trying to implement the intelligent contact lens with flexible devices. Maybe some days later, this kind system for agent Tom Cruise in Mission Impossible（IV/V） would become mission possible.

Conflict
May 28, 2015
Let's talk about a conflict I've faced in my life. I once had a roommate in college who wasn't good at respecting my personal space. He was prone to opening my bedroom door without knocking, or failing to ask permission when he wanted to throw a party.
The source of the conflict was that I felt disrespected by my roommate, who thought that the entire apartment was free for whoever wanted it. I felt disrespected and my privacy felt violated.
To solve this conflict, I approached my roommate and let him know how he felt. He immediately apologized and agreed that he would be much better at respecting my space. This was very successful, and we had no further problems for the rest of the year.
If I could change anything, I would have told him sooner that I had this problem, so it could have been solved faster. From this, I learned how important communication can be when I'm feeling disrespected, and how people will usually immediately apologize and seek to make things right.


Kang Daniel reveals that he only sleeps 3 to 4 hours a night
by sl278Kang Daniel revealed that he gets very little sleep these days.
The popular idol appeared on the guerilla date portion of the November 22 'Entertainment Weekly' broadcast where he revealed that he was staying very busy! When asked how much he slept a night these days, he replied: "around 3 to 4 hours this past week. But I"m thankful. It's been a while, and I feel alive."
When asked about how he feels about his upcoming single album titled 'TOUCHN', he replied "I'm nervous. I want to show a new better side of myself. It's written as if I'm the star of a movie. I think a lot of people will like my title track."
'TOUCHN' will be released on November 25th. Check out footage of the episode below!


Week 8 - Pairing and Feedback
At first I didn't know what to expect from pairing up on coding challenges. It just seemed like there is one screen, one problem, and one developer for any given challenge and having two people would result in toe stepping. While there is still a chance of this happening, it was not the standard behavior as I discovered. Folks were headed into these sessions with a drive to learn and a will to succeed that lead to more indepth knowledge for all involved.
I found the experience of peer pairing to be both exciting and terrifying at the same time. During my first few sessions, I was very worried that I would not have the technical apptitude to keep up with particular partners. There was also a concern that I would be far more capable on a particular challenge than my partner and ulitmately feel like I was pulling the load. The funny part is my fears were realized on both of those examples and it was perfectly fine when the smoke cleared. lol I was able to learn from the more advanced and thankfully was able to teach those with less understanding.
When I first saw there was feedback available for me, I intentionally skimmed over it without reading. I'm unsure as to what I was expecting to see there. It didn't make sense to be worried about it when I really thought about what I may find there. Beyond the filtering that is done to ensure no one recieves nasty feedback, I am operating under the assumption that my peers only wish to be helpful but still it worried me. Of course I ended up reading it and found it to be encouraging after all. Hearing about my personal interaction with another via their thoughts was very interesting.
I found writing feedback to be just as difficult as receiving it. The element of judgement that is inherent with any evaluation is not a very comfortable feeling for me. Its not that I don't want to offer ideas that my peers may run with to improve themselves, its that I've developed a far more passive attitude when evaluating people. Now that I'm actually writing this down, I feel like the personal connections I create in a way hinder me from expressing critical feelings. The old treat others as you would be treated was warped into treat everyone the best all the time. Having expressed this and now being mindful of it, I shall do my best to work through my own personal feelings on the matter so that I may be more helpful to my team in the future.

public abstract class AbstractLogAggregator
Sometimes it is important to have access to raw measurement results. This
base class wrap an existing aggregator and dumps all EtmPoints to a
certain logging implementation using a common log format. Before dumping
the measurement poin the nested aggregator Aggregator.add(etm.core.monitor.EtmPoint)
method is
called.

unless this name was altered using setLogName(String)
.
A EtmPoint will logged using the DefaultOutputFormatter
. You may override
the default implementation by using setFormatter(etm.contrib.aggregation.log.LogOutputFormatter)
.
Due to the direct performance impact this aggregator
should be used in conjunction with a time based buffered aggregator,
such as BufferedTimedAggregator
. Therefore a logging aggregator
chain should look like this: BufferedTimedAggregator -> Implementation of
AbstractLogAggregator -> (Flat/Nested)Aggregator
. Be aware that
log timestamps and measurement timestamps may be out of synch due to buffering.

ActiveSupport::Notifications
provides an instrumentation API
for Ruby.
To instrument an event you just need to do:
ActiveSupport::Notifications.instrument('render', extra: :information) do render text: 'Foo' end
That executes the block first and notifies all subscribers once done.
In the example above render
is the name of the event, and the
rest is called the payload. The payload is a mechanism that allows
instrumenters to pass extra information to subscribers. Payloads consist of
a hash whose contents are arbitrary and generally depend on the event.
You can consume those events and the information they provide by registering a subscriber.
ActiveSupport::Notifications.subscribe('render') do |name, start, finish, id, payload| name # => String, name of the event (such as 'render' from above) start # => Time, when the instrumented block started execution finish # => Time, when the instrumented block ended execution id # => String, unique ID for this notification payload # => Hash, the payload end
For instance, let’s store all “render” events in an array:
events = [] ActiveSupport::Notifications.subscribe('render') do |*args| events << ActiveSupport::Notifications::Event.new(*args) end
That code returns right away, you are just subscribing to “render” events. The block is saved and will be called whenever someone instruments “render”:
ActiveSupport::Notifications.instrument('render', extra: :information) do render text: 'Foo' end event = events.first event.name # => "render" event.duration # => 10 (in milliseconds) event.payload # => { extra: :information }
The block in the subscribe
call gets the name of the event,
start timestamp, end timestamp, a string with a unique identifier for that
event (something like “535801666f04d0298cd6”), and a hash with the payload,
in that order.
If an exception happens during that particular instrumentation the payload
will have a key :exception
with an array of two elements as
value: a string with the name of the exception class, and the exception
message.
As the previous example depicts, the class
ActiveSupport::Notifications::Event
is able to take the
arguments as they come and provide an object-oriented interface to that
data.
It is also possible to pass an object as the second parameter passed to the
subscribe
method instead of a block:
module ActionController class PageRequest def call(name, started, finished, unique_id, payload) Rails.logger.debug ['notification:', name, started, finished, unique_id, payload].join(' ') end end end ActiveSupport::Notifications.subscribe('process_action.action_controller', ActionController::PageRequest.new)
resulting in the following output within the logs including a hash with the payload:
notification: process_action.action_controller 2012-04-13 01:08:35 +0300 2012-04-13 01:08:35 +0300 af358ed7fab884532ec7 { controller: "Devise::SessionsController", action: "new", params: {"action"=>"new", "controller"=>"devise/sessions"}, format: :html, method: "GET", path: "/login/sign_in", status: 200, view_runtime:<PHONE_NUMBER>732178, db_runtime: 40.053 }
You can also subscribe to all events whose name matches a certain regexp:
ActiveSupport::Notifications.subscribe(/render/) do |*args| ... end
and even pass no argument to subscribe
, in which case you are
subscribing to all events.
Sometimes you do not want to subscribe to an event for the entire life of the application. There are two ways to unsubscribe.
WARNING: The instrumentation framework is designed for long-running subscribers, use this feature sparingly because it wipes some internal caches and that has a negative impact on performance.
You can subscribe to some event temporarily while some block runs. For example, in
callback = lambda {|*args| ... } ActiveSupport::Notifications.subscribed(callback, "sql.active_record") do ... end
the callback will be called for all “sql.active_record” events instrumented during the execution of the block. The callback is unsubscribed automatically after that.
The subscribe
method returns a subscriber object:
subscriber = ActiveSupport::Notifications.subscribe("render") do |*args| ... end
To prevent that block from being called anymore, just unsubscribe passing that reference:
ActiveSupport::Notifications.unsubscribe(subscriber)
Notifications ships with a queue implementation that consumes and publish events to log subscribers in a thread. You can use any queue implementation you want.
# File lib/active_support/notifications.rb, line 157 def instrument(name, payload = {}) if notifier.listening?(name) instrumenter.instrument(name, payload) { yield payload if block_given? } else yield payload if block_given? end end
# File lib/active_support/notifications.rb, line 180 def instrumenter InstrumentationRegistry.instrumenter_for(notifier) end
# File lib/active_support/notifications.rb, line 153 def publish(name, *args) notifier.publish(name, *args) end
# File lib/active_support/notifications.rb, line 165 def subscribe(*args, &block) notifier.subscribe(*args, &block) end

public class TcpConnection extends java.lang.Object implements IConnection
OPC UA TCP is a simple TCP based protocol that establishes a full duplex channel between a client and server. This protocol has two key features that differentiate it from HTTP. First, this protocol allows responses to be returned in any order. Second, this protocol allows responses to be returned on a different socket if communication failures causes temporary socket interruption. The OPC UA TCP protocol is designed to work with the SecureChannel implemented by a layer higher in the stack. For this reason, the OPC UA TCP protocol defines its interactions with the SecureChannel in addition to the wire protocol.
Features included in this class:
o Establishing connection, Handshake
o Sync & Async encryption Features excluded in this class:
o Reconnect (See SecureChannel)
o Token Renewal (See SecureChannel)
TcpConnection is instantiated and managed by SecureChannel
which also
handles Reconnection and token renewal.
OpenSecureChannelRequest
and OpenSecureChannelResponse
is
ciphered with asymmetric encryption using the certificates set in initialize.
Asymmetric encryption is omited if server certificate is null. (This is not
allowed in Part 4, but is in Part 6). DiscoveryClient uses unencrypted
connection.
TcpConnection captures security tokens from OpenSecureChannel conversation
and uses them for symmetric messaging. The oldest non-expired token is used.

Adding 1.21 Gigawatts to Applications with RabbitMQ
Presented by James Titcumb (@asgrim)
As your application grows, you soon realise you need to break up your application into smaller chunks that talk to each other. You could just use web services to interact, or
you could take a more robust approach and use the message broker RabbitMQ.
In this talk, we will take a look at the techniques you can use to vastly enhance inter-application communication, learn about the core concepts of RabbitMQ, cover how you can
scale different parts of your application separately, and modernise your development using a message-oriented architecture.
James is the founder of the UK based PHP Hampshire user group and the PHP South Coast Conference. He’s also a Zend Certified Engineer and consultant at Roave. During his
downtime, he continues to run the PHP Hampshire user group and the conference, and keeps up with active contributions to various open source projects.

Improve your budding stevedore potential by learning
about Docker with David McKay
(@rawkode)!
Kickass Development Environments with Docker
Docker, the hottest technology around at the moment. It
swept the Ops world by storm in 2014, became mainstream
in 2015, and now it’s set to dominate the developer
world, in 2016.
Docker is a tool that allows you to package your
application up into a single-runnable distributable
binary - akin to the phar, but in Hulk mode. Docker
allows you, a developer, to specify the exact
environment your application needs to run, across
development; test; staging; and production.
In this talk I will cover the creation of this utopian
distributable and show you how to can compose your
entire production infrastructure locally with only a
small YAML file and without installing a single thing.
Let's say hello to Docker.
at White October
Michael Heap will be presenting Code Archaeology: Becoming Indiana Jones:
Code archaeology is one of the most important skills you’ll ever learn as a developer. How many
times have you been thrown into projects with no environment setup, no documentation, and very
little support from coworkers? Being able to quickly work out how an application is structured
so that you can start making changes is a sought after skill for many employers.
In this talk, we’ll take an open source project that we’ve never seen before and work through the
steps required to get it up and running so that we can start working on features. Once you know
the steps, they can be applied to any project in any language to get you contributing in no time.

How we build phpBB: The Next Generation - Michael Cullum
phpBB is a forum software that has been around since 1999 and is possibly one of the oldest still
developed and widely used open source PHP projects around. In 2007, phpBB 3.0 ‘Olympus’ was released,
and since then we have embarked on an adventure for the next major release of phpBB – 3.1 (also
called 3.2 and 4.0 in the past). This talk goes over where phpBB has come from since the Olympus
release, the mistakes we’ve made, how our mindset changed to integrate Symfony into phpBB, how we
now leverage external libraries and finally how we made it to making 3.1 a finished product, built
using Symfony Components.

Speaker: Stuart Herbert - Why do we test? - View slides
Speaker: Rob Allen - A First Look at ZF3
ZF3 is the framework that took the opportunity to learn from the previous 4 years of ZF2 and be even better than that! Today's PHP projects are built of components installed via Composer and ZF3's architecture reflects this approach; its core components have also been greatly improved in both usage and performance from older versions of the framework. If you're already running a ZF2 application, you'll be able to upgrade your existing application and there will be some excellent support for doing so - we love it when developers get to use new things. If you're a PHP developer with an interest in building excellent, modern applications, then this session is for you.

SC Collegium gets woman member after over a decade
New Delhi: After more than a decade, the Supreme Court Collegium has a woman member with Justice R. Banumathi becoming its part after Chief Justice of India Ranjan Gogoi retired on Sunday. Before her, Justice Ruma Pal, one of the longest-serving women SC judges, was the part of the Collegium system for three years until her retirement on June 4, 2006. She had been appointed an apex court judge on January 28, 2000.
Justice Banumathi, who hails from Tamil Nadu, is now among the top five senior judges of the top court, who as per norms, are part of the Supreme Court Collegium, and recommend the name of judges for appointment in various high courts. Besides Justice Banumathi, Chief Justice of India-designate S.A. Bobde, Justices N.V. Ramana, Arun Mishra, and R.F. Nariman are part of the Collegium. Justice Banumathi will be in the Collegium till July 19, 2020, when she will demit office on retirement.
Born on July 20, 1955, she entered the Tamil Nadu Higher Judicial Service as a direct recruit District Judge in 1988 and worked as District and Sessions Judge in various districts before being elevated as a Judge of Madras High Court on April 3, 2003. Justice Banumathi took the charge as the Chief Justice of Jharkhand High Court on November 16, 2013, and was instrumental in improving the infrastructure of the district judiciary, recruitment and filling up vacancies of ministerial staff. She had published handbooks for the guidance of judicial officers and staff members. She became a judge of the Supreme Court on August 13, 2014. (IANS)

This site uses advanced css techniques
Hardcore Win32 developers are probably familiar with the OutputDebugString() API function that lets your program talk with a debugger. It's handier than having to create a logfile, and all the "real" debuggers can use it. The mechanism by which an application talks to the debugger is straightforward, and this Tech Tip documents how the whole thing works.
This Tech Tip was prompted first by our observation that OutputDebugString() didn't always work reliably when Admin and non-Admin users tried to work and play together (on Win2000, at least). We suspected permissions issues on some of the kernel objects involved, and in the process ran across enough information that we had to write it up.
We'll note that though we're using the term "debugger", it's not used in the Debugging API sense: there is no "single stepping" or "breakpoints" or "attach to process" going on like one might find in MS Visual C or some real interactive development environment. Any program that implements the protocol is a "debugger" in this sense. This could be a very simple command-line tool, or one more advanced such as DebugView from the very smart guys at SysInternals.
The <windows.h> file declares two version of the OutputDebugString() function - one for ASCII, one for Unicode - and unlike most of the Win32 API, the native version is ASCII. Most of the Win32 API is Unicode native.
Simply calling OutputDebugString() with a NUL-terminated string buffer causes the message to appear on the debugger, if there is one. Common usage builds a message and sends it
sprintf(msgbuf, "Cannot open file %s [err=%ld]\n", fname, GetLastError()); OutputDebugString(msgbuf);
but in practice many of us create a front-end function that allows us to use printf-style formatting. The odprintf() function formats the string, insures that there is a proper CR/LF at the end (removing any previous line terminations), and sends the message to the debugger.
#include <stdio.h> #include <stdarg.h> #include <ctype.h> void __cdecl odprintf(const char *format, ...) { char buf[4096], *p = buf; va_list args; int n; va_start(args, format); n = _vsnprintf(p, sizeof buf - 3, format, args); // buf-3 is room for CR/LF/NUL va_end(args); p += (n < 0) ? sizeof buf - 3 : n; while ( p > buf && isspace(p[-1]) ) *--p = '\0'; *p++ = '\r'; *p++ = '\n'; *p = '\0'; OutputDebugString(buf); }
Then using it in code is easy:
... odprintf("Cannot open file %s [err=%ld]", fname, GetLastError()); ...
We've been using this for years.
Passing of data between the application and the debugger is done via a 4kbyte chunk of shared memory, with a Mutex and two Event objects protecting access to it. These are the four kernel objects involved:
| object name | object type |
|---|---|
| DBWinMutex | Mutex |
| DBWIN_BUFFER | Section (shared memory) |
| DBWIN_BUFFER_READY | Event |
| DBWIN_DATA_READY | Event |
The mutex generally remains on the system all the time, but the other three are only present if a debugger is around to accept the messages. Indeed - if a debugger finds the last three objects already exist, it will refuse to run.
The DBWIN_BUFFER, when present, is organized like this structure. The process ID shows where the message came from, and string data fills out the remainder of the 4k. By convention, a NUL byte is always included at the end of the message.
struct dbwin_buffer { DWORD dwProcessId; char data[4096-sizeof(DWORD)]; };
When OutputDebugString() is called by an application, it takes these steps. Note that a failure at any point abandons the whole thing and treats the debugging request as a no-op (the string isn't sent anywhere).
On the debugger front, it's a bit simpler. The mutex is not used at all, and if the events and/or shared memory objects already exist, we presume that some other debugger is already running. Only one debugger can be in the system at a time.
This doesn't strike us as being a low-cost way of sending messages, and the application is at the mercy of the debugger for the speed at which it runs.
We have seen problems for years with OutputDebugString() being unreliable at times, and we're not quite sure why Microsoft has such a hard time getting this right. Curiously, the problem has always revolved around the DBWinMutex object, and it requires that we visit the permissions system to find out why this is so troublesome.
The mutex object is alive and allocated until the last program using it closes its handle, so it can remain long after the original application which created it has exited. Since this object is so widely shared, it must be given explicit permissions that allow anybody to use it. Indeed, the "default" permissions are almost never suitable, and this mistake accounted for the first bug we observed in NT 3.51 and NT 4.0.
The fix - at the time - was to create this mutex with a wide-open DACL that allowed anybody to access it, but it seems that in Win2000 these permissions have been tightened up. Superficially they look correct, as we see in this table:
| SYSTEM | MUTEX_ALL_ACCESS |
| Administrators | MUTEX_ALL_ACCESS |
| Everybody | SYNCHRONIZE | READ_CONTROL | MUTEX_QUERY_STATE |
An application wishing to send debugging messages needs only the ability to wait for and acquire the mutex, and this is represented by the SYNCHRONIZE right. The permissions above are entirely correct to all all users to participate this way.
The surprise occurs when one looks at the behavior of CreateMutex() when the object already exists. In that case, Win32 behaves as if we were calling:
OpenMutex(MUTEX_ALL_ACCESS, FALSE, "DBWinMutex");
Even though we only really need SYNCHRONIZE access, it presumes the caller wishes to do everything (MUTEX_ALL_ACCESS). Because non-admins do not have these rights - only the few listed above - the mutex cannot be opened or acquired, so OutputDebugString() quietly returns without doing anything.
Even deciding to perform all software development as an administrator is not a complete fix: if there are other users (services, for instance) that run as non-admins, their debugging information will be lost if the permissions are not right.
Our feeling is that the real fix requires that Microsoft add a parameter to CreateMutex() - the access mask to use for the implied OpenMutex() if the object already exists. Perhaps someday we'll see a CreateMutexEx(), but in the medium term we have to take another approach. Instead, we'll just hard-change the permissions on the object as it lives in memory.
This revolves around the SetKernelObjectSecurity() call, and this fragment shows how a program can open the mutex and install a new DACL. This DACL remains even after this program exits, as long as any other programs maintain HANDLEs to it.
... // open the mutex that we're going to adjust HANDLE hMutex = OpenMutex(MUTEX_ALL_ACCESS, FALSE, "DBWinMutex"); // create SECURITY_DESCRIPTOR with an explicit, empty DACL // that allows full access to everybody SECURITY_DESCRIPTOR sd; InitializeSecurityDescriptor(&sd, SECURITY_DESCRIPTOR_REVISION); SetSecurityDescriptorDacl( &sd, // addr of SD TRUE, // TRUE=DACL present NULL, // ... but it's empty (wide open) FALSE); // DACL explicitly set, not defaulted // plug in the new DACL SetKernelObjectSecurity(hMutex, DACL_SECURITY_INFORMATION, &sd); ...
This approach is clearly going down the right road, but we still must find a place to put this logic. It would be possible to put this in a small program that could be run on demand, but this seems like it would be interruptive. Our approach has been to write a Win32 service that takes care of this.
Our dbmutex tool performs just this job: it launches at system boot time, opens or creates the mutex, and then sets the object's security to allow wide access. It then sleeps until shutdown, holding the mutex open in the process. It consumes no CPU time.
We've spent a bunch of time with IDA Pro digging into the Windows 2000 KERNEL32.DLL implementation, and we think we have a good handle on how it's working on a more precise basis. Here we present pseudocode (e.g., we've not compiled it) for the OutputDebugString() function, plus the function that creates the mutex.
We are purposely skipping most of the error checking: if things go wrong, it frees up allocated resources and exits as if no debugger were available. The goal here is to show the general behavior, not a complete reverse engineering of the code.
The "setup" function - whose name we have manufactured - creates the mutex or opens it if not already there. They go to some pains to set the security on the mutex object so that anybody can use it, though in practice we'll see that they haven't quite gotten it right.
It might strike some that this is a security matter, but it's really not. Non-admin users do have all the rights necessary to properly use OutputDebugString(), but due to the common mistake of "asking for more rights than required", a legitimate request is denied for a question posed in the wrong form.
But unlike most problems of this type, this is less intentional than most. Most mistakes are where the developer explicitly asks for too much (e.g., "MUTEX_ALL_ACCESS"), but this mask is implied by the behavior of CreateMutex(). This makes it harder to avoid without a change in the Win32 API.
---
While picking apart OutputDebugStringA() in KERNEL32.DLL, it became apparent how a non-admin could likely cripple a system. Once the mutex has been acquired, an application wishing to send a debug message waits up to ten seconds for the DBWIN_BUFFER_READY event to become ready, giving up if it times out. This seems like a prudent precaution to avoid starvation if the debugging system is busy.
But the earlier step, waiting for the mutex, has no such timeout. If any process on the system - including a non-privilged one - can open this mutex asking for SYNCHRONIZE rights, and just sit on it. Any other process attempting to acquire this mutex will be stopped dead in its tracks with no time limit.
Our investigation shows that all kinds of programs send random bits of debugging information (for instance, the MusicMatch Jukebox has a keyboard hook that's very chatty), and these threads are all halted by a few lines of code. It won't necessarily stop the whole program - there could be other threads - but in practice, developers don't plan on OutputDebugString() will be a denial-of-service avenue.
---
Oddly enough, we found that OutputDebugString() is not a native Unicode function. Most of the Win32 API has the "real" function to use Unicode (the "W" version), and they automatically convert from ASCII to UNICODE if the "A" version of the function is called.
But since OutputDebugString ultimately passes data to the debugger in the memory buffer strictly as ASCII, they have inverted the usual A/W pairing. This suggests that for sending a quick message to a debugger even in a Unicode program, it can be done by calling the "A" version directly:
OutputDebugStringA("Got here to place X");
We've discovered that in a Terminal Services environment, debug messages are generally relative to the current session and capturing global debugging messages is problematic. This appears to be because the mutex is now session relative rather than global.

Vonny loves playing with dominos. And so she owns a standard set of dominos. A standard set of dominos consists of 28 pieces called bones, tiles or stones. Each bone is a rectangular tile with a line dividing its face into two square ends. Each square is labeled with a number between 0 and 6. The 28 stones are labeled (0,0),(0,1),(0,2),(0,3),(0,4),(0,5),(0,6), (1,1),(1,2),...,(5,5),(5,6),(6,6). Tommy - the brother of Vonny - build a box for Vonny's dominos. This box is sized 7 x 8 squares. Every square is labeled with a number between 0 and 6. You can see a example box here.
0 3 0 2 2 0 2 3 1 5 6 5 5 1 2 2 3 4 1 4 5 4 4 4 6 6 1 0 5 2 3 0 4 0 3 2 4 1 6 0 1 4 1 5 6 6 3 0 1 2 6 5 5 6 3 3
Now Vonny wants to arrange her 28 stones in such way that her stones cover all squares of the box. A stone can only be placed on two adjacent squares if the numbers of the squares and of the domino stone are equal. Tommy asks Vonny in how many different ways she can arrange the dominos. Tommy assumes that Vonny need a lot of time to answer the question. And so he can take some of Vonny's candies while she solves the task. But Vonny is a smart and clever girl. She asks you to solve the task and keeps an eye on her candies.
The first line of the input contains the number of testcases. Each case consists of 56 numbers (7 rows and 8 cols) between 0 and 6 which represents Tommy's box.
For each testcase output a single line with the number which answers Tommy's question.
Input: 2 0 3 0 2 2 0 2 3 1 5 6 5 5 1 2 2 3 4 1 4 5 4 4 4 6 6 1 0 5 2 3 0 4 0 3 2 4 1 6 0 1 4 1 5 6 6 3 0 1 2 6 5 5 6 3 3 5 3 1 0 0 1 6 3 0 2 0 4 1 2 5 2 1 5 3 5 6 4 6 4 0 5 0 2 0 4 6 2 4 5 3 6 0 6 1 1 2 3 5 3 4 4 5 3 2 1 1 6 6 2 4 3 Output: 18 1

LEARN MORELambda School is live streamed from Silicon Valley to a small group of students participating from all over the world.
Students learn cutting-edge technology from world class instructors at no up-front cost and without having to relocate or acquire expensive housing.
Classes are live, interactive and include one-on-one help, real projects, and frequent code reviews.
You'll only pay tuition once you land a job paying more than $50,000/year in a software-related field.

Once you have a high-paying job, you'll pay back tuition as a fixed percentage of your salary.
Because we invest in you, instead of the other way around, we only make money when you do.
Just like a physical classroom experience, everything at Lambda School is live and interactive. Training takes place in rigorous, live instruction, hands-on projects, pair programming, realistic practice, and frequent code reviews from knowledgeable instructors.
Karthik previously taught Computer Science at Stanford University, and has worked at companies like Stripe and Mozilla.
Ben hails from Hack Reactor and Dev Mountain, as well as iFit, where he was a full stack developer for several years.
Sean comes from the Applied Math program at UC Berkeley, as well as contracting for NASA's Jet Propulsion Laboratory.
Ryan was a senior engineer at several companies, and spent some time at both Dev Mountain and Maker Square (now Hack Reactor).
Unlike most Computer Science programs, we don't start with theory. We start with programming. We jump right into practical knowledge by coding our own applications, then layer in algorithms, abstraction, application architecture, scalability, and theory.
You'll not only learn the practical skills software engineers need to know in order to immediately contribute to an application, but also how to manage large-scale applications, break complex issues down into smaller components, solve problems from first principles, and think abstractly.

This course presents concepts and techniques for representing and manipulating discrete music information, both in real time and off line. Representations of music as explicitly timed event sequences will be introduced, and students will learn how to build efficient run-time systems for event scheduling, tempo control, and interactive processing. The MIDI protocol is used to capture real-time performance information and to generate sound. The course will also cover non-real-time processing of music data, including Markov models, style recognition, computer accompaniment, query-by-humming, and algorithmic composition. This course is independent of, and complementary to 15-322, Introduction to Computer Music, which focuses on sound synthesis and signal processing.

If you just want to see what AWAC can do for you, then install AWAC from the Google Play Store. AWAC acts as a container for a specific type of web-app. By default it will run the introductory web-app that is included as part of the install. However you can also use a web-link to launch AWAC to run your own web-app.
Below are links to launch some web-apps hosted on GitHub:
In addition you can use the launch URL to specify a log file on your mobile device to capture and view output from console.log.
If you want to use AWAC to develop your own Android applications then it is available as an Android Studio project on GitHub. By downloading the project and making some simple configuration changes, you can build your own APK for submission to various app stores.
Examples of simple configuration changes you can make without the need for any coding include:


getSplits Returns all the splits
splits = classifier.getSplits()
Output
- splits Struct-array with the following fields:
- varIdx Index of variable on which the split is
created.
- inversed If true, then the inverse split rule is
used (i.e. left and right branches are exchanged in
the rule expressions below).
- quality The split quality, a positive number. It is
used to choose the best split. (It is also used to
compute variable importance).
- next Index of the next split in the list of splits
for the node (surrogate splits).
- c The threshold value in case of split on an ordered
variable. The rule is:
if var_value < c, next_node = left; else next_node = right; end
- subsetOfs Offset of the bitset used by the split on
a categorical variable. The rule is:
if bitset(var_value) == 1, next_node = left; else next_node = right; end
all the split indices are zero-based indices in the returned
vector.
