Snow
The document contains JavaScript code to simulate falling snowflakes on a web page. It initializes variables like the number of snowflakes, speed, and size. It uses a for loop to create DOM elements for each snowflake and set their initial positions. The snow() function is called on a timer to update each flake's position, handling edges and resetting flakes that fall below the page. Event handlers call functions on window resize and load to initialize and update sizes.
Litebox
The document contains JavaScript code for displaying a pop-up notification on a website. It checks if a cookie exists to determine if the notification has already been closed. If no cookie is found, it displays the notification by adding HTML elements to the DOM. The notification can then be closed by clicking a button, which calls a function to set the cookie and hide the notification.

MongoDB dla administratora
This document discusses using MongoDB as a log collector. It provides examples of storing log data from syslog-ng in MongoDB collections, including filtering and parsing logs. It also gives examples of analyzing the log data through map-reduce to find top IP addresses and provides ideas for other uses like CAPTCHAs, error localization, and analytics.
Oprerator overloading
The document contains C++ code that defines a class called 'space' with member variables x, y, and z. It overloads the unary minus operator - to negate the values of x and y and calculate the sum of the negated values, which is assigned to z. Another class called 'coord' represents 2D coordinates, overloads the + operator to add two coord objects, and returns a new coord object with the summed x and y values. The main function demonstrates creating coord objects, adding two of them, and printing the result.
MongoDB全機能解説2
The document describes MongoDB's GridFS specification for storing and retrieving files that exceed the BSON document size limit of 16MB. It explains that GridFS splits files into chunks, which are stored as individual documents, and maintains metadata about the file such as length, MD5, and filename in a separate collection. It provides examples of using the mongofiles command line tool to list, search, put, and get files from GridFS.

- The document shows examples of basic CRUD operations in MongoDB using PHP drivers and comparisons to PostgreSQL queries.
- Importing and exporting data from MongoDB in JSON or extended JSON formats is covered, including date handling differences from traditional RDBMS.
- Server-side programming in MongoDB using JavaScript is mentioned as an advantage over traditional databases.
Mongo db modifiers
The document demonstrates how to use MongoDB modifiers to update documents. It shows $inc to increment a field value, $set to set a field value, $unset to remove a field, and $push to add items to an array field. Specifically, it increments and sets the "age" field, removes the "age" field, and adds objects to the "remarks" array field to demonstrate the different modifier operations in MongoDB.

It also demonstrates using sequences in for-loops and filters.
Automatically Describing Program Structure and Behavior (PhD Defense)
This document discusses code readability and summarization. It begins by presenting a sample code snippet and noting that understanding code is difficult. It then explores ways to quantify how readable code is, such as using Flesch-Kincaid readability scores and measuring inter-rater agreement through correlation statistics. The document proposes building a machine learning model to predict code readability based on code features and weights learned from human annotations. Potential code features discussed include line length, comments, and identifier length. The overall goal is to automatically describe program structure and behavior to aid in code comprehension.

Mini-curso JavaFX Aula2
The document contains code snippets demonstrating the use of sequences in JavaFX. It shows how to create and initialize sequences of different types, perform operations on sequences like accessing elements, reversing, slicing, and modifying sequences by inserting, deleting, and replacing elements. It also demonstrates using sequences in for-loops and filters.
Automatically Describing Program Structure and Behavior (PhD Defense)
This document discusses code readability and summarization. It begins by presenting a sample code snippet and noting that understanding code is difficult. It then explores ways to quantify how readable code is, such as using Flesch-Kincaid readability scores and measuring inter-rater agreement through correlation statistics. The document proposes building a machine learning model to predict code readability based on code features and weights learned from human annotations. Potential code features discussed include line length, comments, and identifier length. The overall goal is to automatically describe program structure and behavior to aid in code comprehension.

Save
I need help with this maze gui that I wrote in java, I am trying to find the shortest path but I dont
know how to implement the FindshortestPath Method.
I was given this as a stragedy to solve the findshortestpathMethod():
Create two LinkedLists of MazeMap objects. One will be the list of map objects for cells at
distance x from the center. The other will be the list of map objects for cells at distance x + 1.
Initialize the list at distance x to contain a MazeMap object which refers to the center cell of the
maze. Since this map object refers to the center cell, it does not need to refer to any other
MazeMap object, so its MazeMap reference can be set to null. Set the center cell’s visited field
to true to indicate that this cell has already been added to the map.
Set up a loop to run until the maze entrance is mapped. This loop does the following:
Set up a loop to process each map object from the list at distance x. This loop does the following:
i.Get the cell from the map object
ii.If this cell is the entrance cell, set the entrance and break out of the loop!
iii.Check each direction from this cell and for an accessible neighbor cell
Get a reference to that neighbor cell
If the neighbor cell has not already been visited
Set the cell’s visited field to true so its only processed once
Create a MazeMap object that refers to this neighbor cell
Make this MazeMap object refer to the current map object being processed – ie the cell one step
closer to center
Add this MazeMap object to the list at distance x + 1
List at distance x has been processed. The list at distance x + 1 is now complete, so make the list
at distance x refer to list at distance x + 1. Then create a new empty list for the list at distance x +
1.
At this point, the entrance points at the map object which refers to cell 1,1. That map object also
refers to a map object which is one step closer to the center. Write a loop that traverses this trail
of references until it reaches the end (a null reference). For each map object:
Get the cell referred to.
Call the drawCircle method with a color, the cell’s row and column, and SMALL.
Call the delay method with a SHORT delay. This slows down the drawing process so you can
watch the path being displayed.
Advance to the next map object in the list.

All I know about rsc.io/c2go
This document discusses using the C to Go translation tool c2go to translate C code implementing quicksort algorithms into Go code. It provides examples of translating simple quicksort C code, improving the translation by using a configuration file, and how c2go handles standard C functions like qsort by translating them to their Go equivalents. The examples demonstrate how c2go can generate valid Go code from C code but may require some manual fixes or configuration to handle certain data structures or language differences.
dojo.Patterns
The document discusses the Dojo JavaScript toolkit. It provides an overview of what Dojo is, including that it is a lightweight JavaScript toolkit with modular components for tasks like charts, calendars, file uploads and more. It also discusses Dojo's build system for concatenating and minifying files, its module loading system, and patterns used like ambiguous constructors, chaining and deferreds. The document promotes Dojo's large developer community and active development.
Chainer-Compiler 動かしてみた
- The document describes the process of compiling an ONNX model to XCVM using the Chainer compiler. It involves parsing the ONNX model, applying optimization passes like fusion and constant propagation, lowering it to an XCVM program, and then executing the program on XCVM to run the model.
- The compiler represents the model as a Model object containing a Graph. Nodes in the graph are represented by Node objects. Values are represented by Value objects. Tensor data is stored in Tensor objects.
- The XCVM execution engine takes the compiled XCVM program and runs it, interpreting each XCVM operation by calling methods on classes like ConvOp that implement the operations.
Box2D with SIMD in JavaScript
This document discusses optimizing the Box2D physics engine using SIMD in JavaScript. It begins with background on Box2D, describing how it simulates 2D physics with rigid bodies. It then covers SIMD in JavaScript, how Emscripten can compile C/C++ to JavaScript with SIMD, and how Box2D was ported to JavaScript. Performance profiling showed the position constraint solver could benefit from SIMD. The document explores vectorizing math operations and specializing the solver to process groups of 4 constraints simultaneously.

Php engine
This document provides an overview of the inner workings of PHP from three perspectives:
1) The PHP engine consists of the Zend Engine virtual machine, which interprets PHP code, and extensions that add additional features.
2) PHP code is compiled into an intermediate opcode representation before being executed by the Zend Engine.
3) The Zend Engine executes opcode by running each instruction through a handler function in an infinite dispatch loop.
Geolocation on Rails
This document discusses geolocation and provides a brief history. It explains that geolocation is the identification of a real-world geographic location. It then provides a brief history of geolocation techniques from ancient times using smoke signals and celestial navigation to modern GPS systems. The document also discusses geolocation applications and APIs as well as geocoding locations and using the geocoder gem.
Geohex v2 at GMS_nagoya
GeoHex is a hexagonal mapping and geocoding system that assigns unique alphanumeric codes to geographic locations at varying levels of granularity. It offers advantages over traditional latitude/longitude coordinates by being shorter, protecting privacy, and allowing flexible precision. Version 2 extends worldwide coverage, uses a consistent cell size at all latitudes, introduces a new coding system, and supports coordinate transformations and open development.
Experimental dtrace
The document discusses experimental extensions to the DTrace dynamic tracing tool, called XD. XD aims to add control flow constructs like if/else statements and while loops to the DTrace probe language for increased expressiveness. It describes how these extensions are implemented by transforming the XD script into equivalent DTrace code. Issues around integrating XD features like entry-> variables and callers[] predicates into the core DTrace language are also covered.
Javascript & Ajax Basics
Javascript is a dynamic scripting language used widely for client-side web development. It allows asynchronous HTTP (AJAX) requests to update pages dynamically without reloading. Key features include variables, functions, objects, conditionals, closures and exceptions. The DOM represents the structure of a web page and can be manipulated with Javascript to dynamically change content, add/remove elements.
LISA QooxdooTutorial Slides
The document discusses the Qooxdoo JavaScript framework. It introduces Qooxdoo and how it makes JavaScript programming fun again by allowing developers to write applications that run in browsers. It covers key Qooxdoo features like class definitions, inheritance, static and instance members, mixins, and more. The document includes code examples to demonstrate JavaScript concepts like scoping, closures, and working with 'this'.

Pragmatic metaprogramming
Do not repeat yourself, we teach every fledgling software developer. It makes sense as with growing code redundancy the maintenance cost increase. Simple tools such as functions or loops are a great ways to reduce code redundancy but in our quest to avoid code redundancy we sometimes indulge into complexity. Complex code is also costly to maintain. I will demonstrate, using real-world examples, how one can adopt metaprogramming to minimize code redundancy as well keeping the code simple enough for my mom to understand it.
TypeScript Introduction
Not so long ago Microsoft announced a new language trageting on front-end developers. Everybody's reaction was like: Why?!! Is it just Microsoft darting back to Google?!
So, why a new language? JavaScript has its bad parts. Mostly you can avoid them or workaraund. You can emulate class-based OOP style, modules, scoping and even run-time typing. But that is doomed to be clumsy. That's not in the language design. Google has pointed out these flaws, provided a new language and failed. Will the story of TypeScript be any different?

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
