The document summarizes the construction of two major civil engineering projects: the Panama Canal and the Los Angeles Aqueduct. The Panama Canal took two attempts to complete, with the Americans finishing it from 1904-1914 after disease killed many French workers in their initial attempt. The Los Angeles Aqueduct, built from 1905-1913 under William Mulholland, brought water from the Owens Valley to Los Angeles and enabled its growth, though drought and a dam collapse later caused water shortages. Both projects involved overcoming immense technical challenges to transport water or ships across long distances.

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.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
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.

LF Energy Webinar: Electrical Grid Modelling and Simulation Through PowSyBl -...DanBrown980551
Do you want to learn how to model and simulate an electrical network from scratch in under an hour?
Then welcome to this PowSyBl workshop, hosted by Rte, the French Transmission System Operator (TSO)!
During the webinar, you will discover the PowSyBl ecosystem as well as handle and study an electrical network through an interactive Python notebook.
PowSyBl is an open source project hosted by LF Energy, which offers a comprehensive set of features for electrical grid modelling and simulation. Among other advanced features, PowSyBl provides:
- A fully editable and extendable library for grid component modelling;
- Visualization tools to display your network;
- Grid simulation tools, such as power flows, security analyses (with or without remedial actions) and sensitivity analyses;

2. Panama Canal
• 50 mile shortcut to Pacific Ocean
• One of the largest civil engineering projects in history
• The canal was constructed in two stages: 1st 1881-1888 by
French, 2nd 1904-1914 by America.
• America ended up taking over the project, thanks to
President Roosevelt, who paid French $40 million for rights
to the project.
• The canal was completed in 1914.
3. Panama Canal
• Unfortunately, due to working
conditions, many attracted diseases
such as yellow fever & malaria.
• Ridding the canals of these diseases
took three years.
• After 300 tons of sulphur, 120 tons
of insecticide, and 700,000 gallons of
kerosene, the infected mosquitos
were defeated.
• The French had lost around 20,000
people due to disease, while
Americans lost around 7,000.
4. Panama Canal
• The chief engineer for the project was John
Frank Stevens.
• He improved the working conditions &
persuaded Roosevelt to build a lock canal
instead of a sea-level canal.
• Americans seemed to have done a better job
than the French, for the canal was built ahead of
schedule, it was cheaper than expected, working
conditions were improved, and the morale was
higher.
• The canal cost about $639 million to construct.
• Unfortunately, with each entry or exit, 26 million
tons of fresh water is lost into the ocean.
5. Panama Canal
• The canal has three sets of locks: Miraflores
(steps), Pedrio Miguel (1 step), & Gatun (3
steps).
• The hollow gates are 7 feet thick and 82 feet
high.
• Each gate weighs about 730 tons.
• The master wheel weighs 34,000 pounds.
• Water moves by gravity, there are no pumps
to help it.
• By use of the canal, it saves about 8,000 miles
around the tip of South America.
6. Los Angeles Aqueduct
• L.A. started out at as a place of earthquakes &
droughts.
• The water wheels that supplied water was
disintegrating.
• William Mulholland began working for the L.A.
water supply in 1878.
• 1886 he became superintendent of L.A. water.
• 1903 L.A. managed to such dry the last of the
L.A. river, which was the only source of water.
• Water was such a precious resource, people
took baths once a week.
• The water was never pure or clean, just simply
all they could get.
7. Los Angeles Aqueduct
• Mulholland built the L.A. aqueduct, which went from the Owens river through the San
Fernando Valley.
• Thousands of people worked on the building of the aqueduct with no air conditioning, no
hard hats, and no water.
• They were able to make it across in 5 years.
• November 5, 1913-celebration of completion of L.A. aqueduct
• Mulholland’s famous speech: “There it is, take it.”
• Water was abundant and started the building and construction of what it now L.A. today.
• From desert to the land of Eden!
8. Los Angeles Aqueduct
• Mulholland changed history, and L.A. named a school, dam, reservoir, & highway after him.
• L.A. ended up growing at such a fast rate of speed that water was already running low after just 10 years of building
the aqueduct.
• Drought happened to occur again, and people were so outraged they ended up blowing up the aqueduct.
• Mulholland came up with the idea for construction of the St. Francis Dam in San Franciscito Canyon.
• The dam ended up collapsing, sending a huge tidal wave of concrete over the surrounding communities.
• The dam had killed as many people as the San Francisco earthquake.
• Mulholland’s reputation was crushed and he resigned after 50 years.
9. Los Angeles Aqueduct
• L.A. kept having to find new resources for water because of how fast it
continued to grow.
• A new aqueduct was built connected to the Colorado River, then to the
Mono lake.
• People constantly worried about supply instead of conservation.
• 1976 Mono lake had fallen 40 feet, but was able to have water restored to it
thanks to activists in 1988.
• Today, L.A. uses the water that is provided, & if there is a shortage, oh well!
