PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Assignment vector raster

Raster
A raster data type is, in essence, any type of digital image represented by reducible and enlargeable
grids. Anyone who is familiar with digital photography will recognize the Raster graphics pixel as the
smallest individual grid unit building block of an image, usually not readily identified as an artifact shape
until an image is produced on a very large scale. A combination of the pixels making up an image color
formation scheme will compose details of an image, as is distinct from the commonly used points, lines,
and polygon area location symbols of scalable vector graphics as the basis of the vector model of area
attribute rendering. While a digital image is concerned with its output blending together its grid based
details as an identifiable representation of reality, in a photograph or art image transferred into a
computer, the raster data type will reflect a digitized abstraction of reality dealt with by grid populating
tones or objects, quantities, cojoined or open boundaries, and map reliefschemas. Aerial photos are one
commonly used form of raster data, with one primary purpose in mind: to display a detailed image on a
map area, or for the purposes of rendering its identifiable objects by digitization. Additional raster data
sets used by a GIS will contain information regarding elevation, a digital elevation model, or reflectance of
a particular wavelength of light, Landsat, or other electromagnetic spectrum indicators.
Raster data type consists of rows and columns of cells, with each cell storing a single value. Raster data
can be images (raster images) with each pixel (or cell) containing a color value. Additional values
recorded for each cell may be a discrete value, such as land use, a continuous value, such as
temperature, or a null value if no data is available. While a raster cell stores a single value, it can be
extended by using raster bands to represent RGB (red, green, blue) colors, colormaps (a mapping
between a thematic code and RGB value), or an extended attribute table with one row for each unique
cell value. The resolution of the raster data set is its cell width in ground units.
Raster data is stored in various formats; from a standard file-based structure of TIF, JPEG, etc. to binary
large object (BLOB) data stored directly in a relational database management system (RDBMS) similar to
other vector-based feature classes. Database storage, when properly indexed, typically allows for quicker
retrieval of the raster data but can require storage of millions of significantly sized records.
Vector
In a GIS, geographical features are often expressed as vectors, by considering those features
as geometrical shapes. Different geographical features are expressed by different types of geometry:
Points
Zero-dimensional points are used for geographical features that can best be expressed by a
single point reference—in other words, by simple location. Examples include wells, peaks,
features of interest, and trailheads. Points convey the least amount of information of these file
types. Points can also be used to represent areas when displayed at a small scale. For example,
cities on a map of the world might be represented by points rather than polygons. No
measurements are possible with point features.
Lines or polylines
2. One-dimensional lines or polylines are used for linear features such as rivers, roads, railroads,
trails, and topographic lines. Again, as with point features, linear features displayed at a small
scale will be represented as linear features rather than as a polygon. Line features can measure
distance.
Polygons
Two-dimensional polygons are used for geographical features that cover a particular area of the
earth's surface. Such features may include lakes, park boundaries, buildings, city boundaries, or
land uses. Polygons convey the most amount of information of the file types. Polygon features
can measure perimeter and area.
Each of these geometries are linked to a row in a database that describes their attributes.
For example, a database that describes lakes may contain a lake's depth, water quality,
pollution level. This information can be used to make a map to describe a particular attribute
of the dataset. For example, lakes could be coloured depending on level of pollution.
Different geometries can also be compared. For example, the GIS could be used to identify
all wells (point geometry) that are within one kilometre of a lake (polygon geometry) that has
a high level of pollution.
Vector features can be made to respect spatial integrity through the application of topology
rules such as 'polygons must not overlap'. Vector data can also be used to represent
continuously varying phenomena. Contour lines and triangulated irregular networks (TIN) are
used to represent elevation or other continuously changing values. TINs record values at
point locations, which are connected by lines to form an irregular mesh of triangles. The face
of the triangles represent the terrain surface.
