The testers had mixed experiences using the Chef'd website to complete tasks. Both found the initial overview satisfactory but encountered issues with consistency when selecting meal preferences and being unable to find specifically spicy meal options. The biggest usability problems were the inconsistent highlight colors when selecting foods causing confusion, and meal images expanding fully on click without providing additional information to help find spicy options. Overall the site was rated positively but could be improved with more consistent interactions and ensuring relevant information is easily discoverable.

This paper is from a series of tests conducted to gather information about how well Chefs.com is runnining and what could be done to improve the overall site for excellent user satisfaction
The usability tester conducted tests of the Chefd.com website with two participants. Both participants were initially able to find the Spoon University meal plan but struggled with subsequent steps of selecting dietary preferences and number of meals. They were confused when pages loaded to the bottom and options were opposite of their selections. While one participant figured out preferences had to be deselected, the other took multiple tries to understand. Both found the experience frustrating.
The usability test uncovered several issues with the Spoon University website. Testers struggled to build a meal plan within their budget and found it difficult to edit or change their meal plan. They were frustrated that clicking back would restart the meal plan process. While searching for a spicy meal, the search function took them away from Spoon University meals. Overall, the testers found it challenging to navigate the site and customize their orders. Improved editing tools, on-page help text, and a search function limited to Spoon University would enhance the user experience.

Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.
State of Artificial intelligence Report 2023kuntobimo2016
Artificial intelligence (AI) is a multidisciplinary field of science and engineering whose goal is to create intelligent machines.
We believe that AI will be a force multiplier on technological progress in our increasingly digital, data-driven world. This is because everything around us today, ranging from culture to consumer products, is a product of intelligence.
The State of AI Report is now in its sixth year. Consider this report as a compilation of the most interesting things we’ve seen with a goal of triggering an informed conversation about the state of AI and its implication for the future.
We consider the following key dimensions in our report:
Research: Technology breakthroughs and their capabilities.
Industry: Areas of commercial application for AI and its business impact.
Politics: Regulation of AI, its economic implications and the evolving geopolitics of AI.
Safety: Identifying and mitigating catastrophic risks that highly-capable future AI systems could pose to us.
Predictions: What we believe will happen in the next 12 months and a 2022 performance review to keep us honest.
End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Discussion on Vector Databases, Unstructured Data and AI
https://www.meetup.com/unstructured-data-meetup-new-york/
This meetup is for people working in unstructured data. Speakers will come present about related topics such as vector databases, LLMs, and managing data at scale. The intended audience of this group includes roles like machine learning engineers, data scientists, data engineers, software engineers, and PMs.This meetup was formerly Milvus Meetup, and is sponsored by Zilliz maintainers of Milvus.
Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdfGetInData
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

Choosing Participants
Tester 1: Mariah Barnes
My first tester is Mariah Barnes, a 21-year-old female marketing major. In addition to
being a full time student, she is a part time worker in the J.W. jones student union with
Aramark. She holds an exec position in one organization and is a member of two others. Her
days consists of studying, watching television and browsing the web. She utilizes the internet
4. about 80 hours a week. She is not very active on social media. She described the split between
social media and browsing to be about 25% and 75%. She considers herself to be a high-
experienced user of the internet. She is not familiar at all with Chef’d but she frequently shops
online and has a high interest in food. I would consider her a reasonable tester because of her
internet habits. She rarely uses social media, so she spends a lot of time on other types of
websites meaning she interacts with many other formats and user interfaces. In addition to her
versatile internet usage, she is very involved in her food decisions. She counts calories and
carbs and loves to cook.
Environment for Tester 1
Location of Test: The test was conducted in her suite style dorm, Forrest Village
Apartments, in the living room. This location was appropriate for this tester
because this is where she does most of her browsing.
Physical Environment: Prior to the testing, the tester turned on the lights being
that it was night and there was no natural light. The lights were yellowed, more
like home bulbs rather than a white light. To add to the yellow of the light, the
walls were almost a dark yellow brown color as well. Her roommate was in the
living room with us and was a slight distraction. Throughout the tasks, she would
share something with Mariah that she saw on the internet.
Technical Environment: Mariah used Google chrome on her school issued
laptop. Because we were on campus, she was connected to the universities Wifi.
No add-ons or plug-ins on her browser. She uses the default version.
5. Tester 2: Danielle Rivera
Tester 2 is Danielle Rivera. She is a 22-year-old student at Northwest Missouri State
University. She is currently unemployed but it is a full time psychology major who is involved on
campus. She spends about 12 hours a day browsing the web, which is about 84 hours a week.
She says she spends about 40% of her time on social media and 60% elsewhere. She does a lot
of research for her classes. I think this makes her a reasonable tester because she aligns with
the target audience for Chef’d. She is a busy college student so she needs meals that don’t
require a long time to prepare and as far as user experience, I hope to gain insight from her
about the simplicity of the site. She considers herself a high experienced internet user.
Environment for Tester 2
Location of Test: The test was conducted in her bedroom off-campus. This is
where she uses the internet the most. She does her homework and recreational
browsing here. she is sort of lying in bed.
Physical Environment: The room was well lit. There were no distractions. The TV
was not on. She did not use her phone at all , it was silenced before we started.
Technical Environment: Danielle’s internet provider is
Sudden link and she was using her school provided laptop.
The brightness was on 100%. After the test she allowed
me to run an internet test and the results are in the
screenshot. She used Google chrome with no add-ons or
plug-ins.
6. Test Results
Both Danielle and Mariah were overall satisfied with the initial overview of the site.
They felt like there was adequate information on the homepage to understand the use of the
site. All of the information, in their opinion was designed well and easy to understand. Both
commented on the high quality photos. Mariah’s experience started a bit different than
Danielle’s. Mariah was prompted with a 10% discount upon arrival to the site. She did not
notice the “X” to close the pop up for a while and read the site through the darkened area for a
while. Mariah did not watch the introductory video on the homepage while Danielle did. I think
this gave Danielle better insight to the company’s personality. She noted the interracial couple
in the video and admired the fact that that was something they were willing to feature. Both
scrolled all the way down the homepage using the scroll bar on the right.
Task 1: Build a Spoon University meal plan and determine the total weekly cost.
Summary for Both Testers:
Tester 1 Tester 2 Average
Average Satisfaction 1 4 2.5
Success Rate 0% 100% 50%
Highlights
1) Testers were unsure about selecting or deselecting meat options
2) Testers disliked re-doing the entire meal plan to make changes
7. Biggest Problem: The biggest problem within this task is the highlight color of the
bubbles. In the allergy prompt, the bubbles are grey and when you click, they turn
orange.
When asked about meats, the bubbles are orange and when you click them, they turn
grey.
This inconsistency causes confusion as far as selecting and deselecting. Testers clicked
on their preferences which I believe means they would not like to be presented those
options. This problem could be the determining for someone who wants a specific meat
choice.
Alignment to Heuristic: Consistency and standards
This problem matches this heuristic because it makes the user wonder or make
assumptions about the selection process because of the color changes.
Task 2: You have the budget to coverone extra meal per week, but you want it to be spicy
meal. Determine your spicy meal options and choose one meal that you are willing to
prepare.
8. Highlights
1) Testers did not know immediately to scroll down for information
2) Tester cannot find spiciness
Biggest Problem: The tester not being able to find spiciness is the biggest problem. The images
when you click on the meal are so large that it takes up the entire screen, which looks like the
picture expanding is the only thing that happens when you click on the meal. It took the testers
a little longer than it should have to figure out that they had to scroll down for meal details. The
testers clicked on the meal, the picture expanded, and they would click the X in the corner
without scrolling.
Alignment to heuristic: Flexibility and efficiency of use
This heuristic best aligns because an expert user may know that the larger image is for
photographic enhancement and to use the scroll bar, while a less experienced user might think
there is nothing more to the page.
Tester 1 Tester 2 Average
Average Satisfaction 4 5 4.5
Success Rate 50% 100% 75%
9. Task 3: Ensure none of your meals, “Grab ‘n’ Go’s” or snacks is more than 450 calorie per
serving. If the calorie count is too high, swap the item for another.
Tester 1 Tester 2 Average
Average Satisfaction 2 1 1.5
Success Rate 0% 0% 0%
Highlights
1) Tester can’t find information
2) Testers meal won’t load
Biggest Problem: The biggest problem in task 2 is re-occurring for task 3 since the
information is in the same place. In addition to this, the macaroni option would not load.
Alignment to heuristic: Visibility of system status
The macaroni not loading most aligns with this heuristic because there is no explanation
to the user about it. If it is because it is sold out, the user was never informed
Task 4: Assume/pretend that it is Monday at 3:30 p.m., and you plan to prepare the spicy
meal on Saturday night. Will the meal arrive in time?
Highlights
1) No issues

Recommendations to improve UX
Single problem being fixed: Task 1 : Meat selections
Problem Improvement:
I do think that being exposed to potential purchases is the most important part of this
process therefore addressing the issue of task 1 would be my first concern. If a user wants a
meal with chicken, because they only eat chicken, if they mistakenly deselect chicken, they
will not have any options to choose. To fix this, I would have the buttons grey and turn
orange when selected. I think that it should be the same as the allergy prompt because it sets
precedence and expectations to the user.
11. This is what it would look like if the selections were greyed when deselected and orange
when selected.
It would be consistent with the allergy prompt below.
