Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

How we managed to grow and scale a RAG application from zero to thousands of users in 7 months. Lessons from technical challenges around managing high load for LLMs, RAGs and Vector databases.
From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

LF Energy Webinar: Carbon Data Specifications: Mechanisms to Improve Data Acc...DanBrown980551
This LF Energy webinar took place June 20, 2024. It featured:
-Alex Thornton, LF Energy
-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
"Choosing proper type of scaling", Olena SyrotaFwdays

"$10 thousand per minute of downtime: architecture, queues, streaming and fin...Fwdays
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

18. New Ideas
Rationalism became the
new imperative for design.
Out with decoration and
formalism, in with logic
and standardization.
Jan Tschichold, “Die neue Typographie” 1928.
Instructions for the standardized layout of A4 letterhead.
19. The More Things Change…
Modernists looked to build a new aesthetic by
• Deriving beauty from the innate qualities of
the machine
• Championing standardization
Sound familiar?
20. …The More They Stay the Same
There is a strong overlap between what
motivated grid usage nearly a century ago and
what motivates grid usage today.
• Deriving beauty from the innate qualities of
the browser
• Championing standardization
21. Paul Rand for IBM
Paul Rand, IBM Annual Report, 1975
41. Canvas Area
• Less left and right
margins
• Approximately 960 px
wide by 650 px tall
42. The Big Ad
The most useful ad unit to design for is the Big
Ad.
336 px wide by 280 px tall as established by the
Internet Advertising Bureau.
43. Big Ad width:
336 px
Other Ad Sizes
A design based on the Big
Ad will also accommodate
the width of the other
popular ad unit sizes
Medium Rectangle
300 px wide by
250 px tall
Half-page
300 px wide by
600 px tall
44. The Utility of Constraints
Ad units complicate things, but they!re actually
very helpful because they serve as fixed
constraints.
Constraints are the mother of design
invention.
46. Units & Columns
Units are the basic building blocks of a grid.
They!re all uniform.
Columns are the groupings of units that create
the visual structure of the page. They are not
necessarily uniform.
In this example, four units are combined to create a single column.
47. The Rule of Threes… or Fours
In general, we want to
create units in multiples of
three or four.
Twelve is ideal, because
it!s a multiple of three and
four.
48. Twelve Units Can Combine into 3 Columns…
Three columns of four
units each.
54. Formula
Canvas - ((Total Units -1) x Gutter) ÷ Total Units = Unit
950 - ((16 -1) x 10) ÷ 16 = Unit
(Don!t worry about doing it this way.)
55. Round-up the Ad Column
Round up the ad unit
column to an even 340 px
width.
56. Divide the Ad Column
Divide the ad column into
two units of 165 px each,
with a 10 pixel gutter.
(340 - 10) ÷ 2 = 165
57. Extrapolate Units
Yields 5 units of 165 px
each for a total width of
just 865 px.
These could be
subdivided into 10 units
but a 10 unit grid is
difficult to work with.
62. Subdivide the Units
Eight units is a good
number, but we can
subdivide it even further
into a 16-unit grid for
added flexibility.
These units are 50 px
wide
63. Consolidate Units into Columns
A 16-unit grid allows us to
create two equal columns
in the left region.
67. Round-up the Ad Column
For a tighter look, we can
round up the ad unit to
338 px.
68. Divide the Ad Column
Divide by five this time,
with four 7 px gutters, for
62 px units.
(338 - (4 x 7)) ÷ 5 = 62
69. Extrapolate Units
Yields 14 units of 62 px
each for a total width of
959 px.
Fourteen is a strange
number, but sometimes
that makes things more
interesting.
70. Consolidate Units into Columns
Allows the left region to be
consolidated into 3
columns.
83. Accounting for Behavior
In digital media, those
boxes are often behavior.
That is, they may or may
not appear persistently.
When they!re not there, it
can cause visual
misalignment.
87. The Box Model
It!s actually useful to use
the CSS box model as a
model for imagining the
visual space around any
element.

88. The Box Model in Practice

GRID LINE
98. Visual Grouping through Rules
Add rules between most
nav items and to visually
combine multi-item groups
like Small Business and
Services together.
100. Adjunct to the Box Model
Every box should be laid
out using the same
principles as used in
framing.
Padding for all sides
should be visually equal.
But only the top, right and
left padding should be
mathematically equal. The
bottom should be taller.
Text
103. Applicable to All Elements
The illusion of visual
equality is enhanced
when elements are
stacked.

104. Items and Rules
Even multi-item groups
should be treated the same
way.
