At Jazkarta, our Plone projects typically consist of a mix of custom functionality and theming. The client's budget is usually fixed and their requirements are imperfectly defined at the start of the project. This cries out for an agile, iterative approach, however our development environment is not what most agile experts would recommend. No one is co-located - our clients are remote and our developers are distributed, and they are not working full time on a single project.
Sally Kleinfeldt describes Jazkarta's approach to managing a Plone website development project in an agile fashion, with a part time, distributed team. Topics include roles, scheduling, estimation, and project management tools.

This document summarizes how Plone can be used in higher education for intranets, directories, microsites, and online courseware. It discusses how Plone allows for news and event publishing, department pages, important documents, FAQs, and access for both staff and students on intranets. It also describes the FacultyStaffDirectory and CMFBibliography tools for user directories, how microsites can create separate identities for schools and units while maintaining shared infrastructure, and how eduCommons is an open courseware management system used by many colleges and universities.
The document outlines David Allen's Getting Things Done (GTD) productivity system. GTD involves collecting all tasks and projects, processing and organizing information into different lists like Projects, Actions, and Waiting For. It also involves weekly reviews to keep organized and plan by reviewing those lists. The overall goal is to empty your head of outstanding tasks and commitments by capturing, clarifying and organizing everything into external lists and calendars.

[Workshop] Analyzing Your Deliverables: Developing the Optimal Documentation ...Scott Abel
Presented by Nicki Bleiel at Documentation and Training LIfe Sciences, June 23-26, 2008 in Indianapolis.
Documentation deliverables have evolved beyond manuals and online help in recent years, and with the emergence of Web 2.0, things are changing faster than ever. Technical communicators have many more options to enhance the user experience, and developing many of them provide the opportunity to work with other departments to find a more holistic approach to content development and delivery. But there is no one-size-fits-all set of solutions. This workshop will review the types of analysis you need to do to determine which deliverables are right for your project, your customer, and your company.
Other factors that can’t be ignored, such as translation needs, staff/time constraints, file size limitations, corporate image and control, and proprietary concerns will also be discussed, including:
Analyzing the Product
* Intended audience; delivery method (desktop, web application, etc.); competitor offerings; software development methodology. The UI as part of the Help system. Product Management expectations.
Identifying User Wants and Needs
* Preferences and expectations for information; work environment; knowledge and experience levels.
Ascertaining Internal Needs and Opportunities
* Working with Training, Support, and Marketing to reduce duplication and provide the user with consistent, useful information.
* Finding ways to incorporate information from other departments to improve documentation.
Accessing Deliverable Options
* What is the optimum mix for the product?
* The traditional: online help, manuals, embedded help, job aids, forums, web sites, technical support knowledgebases.
* Emerging trends: wikis, blogs, RSS feeds, software demonstrations, podcasts, and other collaborative tools. They can supplement and/or enhance the traditional. Or, they may be a better fit for internal knowledge management or marketing use.
Optimizing the Library
* Single-sourcing; best practices for structuring information; continuous publishing

The document discusses best practices for writing reusable Django applications. It recommends:
1) Focusing each application on doing one thing well rather than trying to encompass multiple unrelated features.
2) Not being afraid to split features across multiple specialized applications rather than cramming everything into one monolithic application.
3) Writing applications to be flexible and allow for customization through overrides and settings rather than having rigid hardcoded implementations.
4) Building applications in a way that is decoupled from any specific project structure so they can be easily distributed and reused in different projects.
This document summarizes the changes made to Django's admin interface with the introduction of newforms. Key changes include decoupling the admin from models by defining ModelAdmin classes separately in admin.py, using formsets and model formsets, adding support for generic inlines, and allowing media definitions on forms and widgets. Other enhancements include refactoring of inline handling and improvements to determining changed data in formsets.
This document discusses techniques for improving the performance of Django projects handling high traffic volumes. It identifies common areas of concern like database performance, web server configuration, caching, and template rendering. It provides examples of optimizing ORM queries, implementing object caching with invalidation plans, profiling code to identify bottlenecks, and leveraging tools like Varnish, memcached, and database query profiling. The key lessons are to develop a caching strategy, use profiling to optimize problem areas, and consider alternative web server software or configurations to improve performance.

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.
"$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.
This talk will cover ScyllaDB Architecture from the cluster-level view and zoom in on data distribution and internal node architecture. In the process, we will learn the secret sauce used to get ScyllaDB's high availability and superior performance. We will also touch on the upcoming changes to ScyllaDB architecture, moving to strongly consistent metadata and tablets.
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).

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

We will talk about system monitoring from a few different angles. We will start by covering the basics, then discuss SLOs, how to define them, and why understanding the business well is crucial for success in this exercise.

The Birth of Tabula Rasa
build a dummy site to guide
development of apps
If you want to build a ship, don’t drum up the men to
gather wood, divide the work and give orders.
Instead, teach them to yearn for the vast and endless sea.

18. Pinax proposed by Orestis Markou
So far it's just my new django-email-confirmation app tied
together with password change and reset, login/logout, with the
beginnings of a tab-style UI. There's a ton more I want to refactor
out of my existing websites to put into it as well as adding
support for OpenID and the stuff I'm starting to do for django-
friends.
Even if one doesn't use Pinax as the starting point of a website,
I'm hoping it will prove very useful for another goal, namely a
quot;hostquot; project to develop and tryout reusable apps.

be a demo site is a useful site in its own right,
irrespective of whether you care or even know about the
Pinax platform underlying it. So it will be moving over to
a new site with a new identity soon.
