"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

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.

1. GIRAFFES
The Giraffe is a famous animal of Africa. Giraffes live near the trees and they especially
like acacia trees. Because they eat kind of leaves on the dryland and they move in
groups.
Giraffes have 4 long and strong legs, a long neck, a long tongue
and a long tail. Also they have 2 short horns. They are very tall
which is 5.5metres for males and 4.5metres for females. And
when they run they can go 100kilometres per hour.
The Giraffe has just one baby. They have a 400 to 450 days
gestation period. The baby`s height at birth is on average 2
metres. Also they feed their young on milk for 2years and then
they take care of the baby for more than 1-2years.
The Giraffe is protected by the government in Africa. The Government has plans
including collecting seed from acacia for food, migrating the girafes into national park or
reserve areas and controlling the population.
2. Siamese Crocodile
The Siamese crocodile is a native of Thailand.
In Thailand we have 3 types of crocodile: Siamese, C. porosus and Tomistoma. It looks like a lizard but is bigger
and longer. They have a long head and flat body and tail, short legs and powerful jaws. Their skin has scales and
is very rough. They also have webbed feet and sharp claws. Their legs at the front have five fingers but the legs
at the back have four fingers.
They eat meat and their favourite food is frogs, fish, deer, cows, dogs and birds.
The crocodile lays between 20-50 eggs and adults feed mainly on fish but also eat frogs, birds and small
animals.
In Thailand they protected because they are used for business. In the summer they like to live in the water and in
the winter they like to live in the land. They stand with their mouth open all day.

3. Siberian Tiger
Siberian tigers are the world’s largest cats. They live in eastern Russia, China
and North Korea.
They have brown striped fur and powerful legs. They lie in wait to attack their
victims’ hungry tiger can eat as much as 27kgs in one night. Most tiger avoid humans, but a few do become
dangerous man-eaters’.
They deliver two to six cubs. Cubs cannot hunt until they are18 months. They remain with their mother for two to
three years until they become independent.
There are protected, because there are only about 400-500 Siberian tigers living in the wild. Also people have
reduced the woodland so they have become endangered. Also their body parts are used in traditional Chinese
medicine which is a threat to Siberian Tigers.
4. Royal Bengal Tiger
The Royal Bengal Tiger is the native animal of Bangladesh and it lives in Sundarbans, area in the east of
Bangladesh.
The royal Bengal tiger is reddish orange with narrow black, gray of brown stripes. The underside is creamy or
white with darker stripes and it has icy blue eyes. It feeds on pigs, deer and buffalo. The tiger can consume as
much as 40 kg of meat in one feeding.
The weight is 225 kg and female, 135 kg. It looks like a cat but it is larger than a cat. The tiger is timid and it is
secretive and essentially solitary. It can jump 5 and 6 meters and it likes water and can swim very well. The tiger
hunts mostly at dusk and dawn because their stripes help them hide in the shadows of tall grasses. They stalk
and pounce because they are not able to chase prey a long distance. They are commonly seen in the shade or
wading in pools to cool off.
It is estimated that there are less than 3,000 Royal Bengal Tiger left in the wild.

5. Report about the Leopard
The leopard is a native of Taiwan. The
animal`s appearance looks like a tiger
with dark grey or ochre in color. They
have strong tails to help them to balance
while perched on tree branches. Their
legs are short and stout with broad paws.
The leopards are carnivores as they eat
snakes, birds, monkeys, etc.They live in
forests at elevations of up to 80000 feet.
Most of the time they live in trees.
The leopard’s habitat is the jungle and
they move during the night. The forests
are their home but many people like
shooting this animal so they might

6. Tiger Snake
Introduction
The tiger snake is a type of venomous snake found in southern regions of
Australia including its coastal Islands and Tasmania.
Habitat
Tiger snakes are most often seen near creeks, rivers and swamps. They
can also be found in dry areas. They can climb small trees and shrubs. Tiger snakes are active during the day
and also during the night in warmer weather.
Appearance
Tiger snakes are thick-bodied snakes, they are usually around 1 m long but many grow up to 2 m. Their head is
slightly wider from their neck. Tiger snakes range in colour from grey, brown, black, red and yellow. The belly can
be cream, yellow, grey, and olive green with the head dark grey bluish or black
What they eat
Tiger snakes are largely frog predators. When young they eat frogs, black rats but they also eat other
reptiles, birds, small mammals and fish. They have poisonous venom that helps break down the prey in their
stomach. The warmth from the son also helps the digestion of food.

7. Emu
The emu is a native of Australia. It’s the world’s third largest
bird. But they can’t fly.
The emu lives all over Australian grasslands. They like to stay
around water. But they avoid heavily populated areas, dense
forest and arid areas.
The emu is 1.5 to 2 metres tall and about 36 kilograms of
weight. They have 3 toes and long legs. The emu can be up to
1.5 metres wide. The female is larger than the male.
The emu feeds on grass, leaves and small insects. The female
emu lays up to 20 eggs. Then the male makes the nest and
sits on the eggs for about 8 weeks. The male emu looks after
the young until they are 2 years old.
8. Report on Komodo Drag By Irma
The Komodo dragon is a native of Flores
an Indonesian island.
The Komodo dragon lives in dry open
land, savana and tropical forest. They
like dry and hot places. It is mostly active
in the day time, because it is cold
blooded. Although it is sometimes active
in the night too. They like to live alone,
only the Komodo come together to breed
and eat.
They can run up to 20 kilometres per
hour and accelerate up to 4.5 meters at
top speed, in a period of short time.
The Komodo dragon digs the holes for
protection with powerful legs and it has sharp claws. This hole can be 1-3 metres wide. Because it is very big
and sleeps in the holes, it is able to keep warm though the night. The Komodo usually hunts in the afternoon,
Komodo dragon has special resting places on ridges that catch cool sea breezes.
The Komodo dragon has a tail as long as its body and about 60 sharp teeth that can grow up to 2.5 cm long. It
also has a long, yellow forked tongue. Its saliva is red because the gums almost completely cover its teeth.
The Komodo dragon is a reptile.
9. Carabao
The Carabao is a type of water buffalo is the national animal of The Philippines.
Carabaos are well adapted to a hot and humid climate. Wild carabaos can be found on grassy lands near water
such as lakes and wide rivers and domestic carabaos usually live on a farm because the farmers use them for
pulling ploughs. They also produce large quantities of milk.
The Carabao eats grass and vegetables.
They have fairly long grey or black hair thinly covering their huge body and their weight is almost 2000 pounds.
Since they have no sweat glands, they cool themselves by lying in a water hole or mud during the heat day. They
are mammals and the female carabaos can deliver one calf each year.

10. Koala
Introduction
The koala is a native animal of Australia. No other animal in the world is like
the koala. They live in small groups and are called marsupials.
Habitat
The koala lives in bush land areas. They live in high branches of the trees.
Normally the koala’s breeding season is from August to February. At this
time the young from previous years are ready to leave their mother and
become independent. Usually a female has one young each year but may
not breed in some years.
Appearance
Koalas have soft, thick and grey or brown fur on their back and white fur on
the stomach. They have a large hairless nose and round ears. They don’t
have a tail. Adult koalas measure between 64 to 76 cm in length and weigh
between 7 and 14 kg. The female koala has a pouch to carry her baby. The
tiny baby is called “Joey”. They also have long toes and sharp claws. They
are mostly silent in the day time and moving around at night time.
Feeding
Koalas are herbivores. They usually eat grass, plant and leaves. The baby
koala feeds on her mother’s milk inside the pouch.
80 years ago koalas were in a very danger condition because
they were hunted by people for their fur and people used koala’s
fur to make jackets, blankets and purses but now this is illegal.
11. Elephants
Introduction:
There are two different types of elephants, Asian and
African elephants. Sometimes people split the Africa
elephant in to Forest African elephant and Bush African
elephants.
Appearance:
Elephants are the largest land-living mammal in the world.
Both genders of African elephants have tusks however only
male Asian elephants have tusks. They use their tusks for
digging and finding food. Elephants have large, thin ears mostly made of blood vessels, which regulate an
elephant’s temperature. Their trunk can grow to about two meters long and weigh about 140kg!!!
How they live:
Female elephants are called cows. Females start having calves at 12 years old, they are pregnant for about 22
months. Elephants have no natural predators, however lions will sometimes prey on young elephants. Elephants
lift food and water with their trunk.
Food:
Elephants can drink up to 210 liters of water a day!! Elephants are herbivores. Herbivores are animals that eat
plants only. Elephants look for food 16 hours a day, collecting leaves, twigs, bamboo and roots.
Conclusion:
Elephants are the largest land mammal in the world. They drink a lot of during their lives. They are a social
animal, living in herds.
