Scaling with Scala: refactoring a back-end service into the mobile ageDragos Manolescu
Services built with 20th century programming languages are reaching their scalability limits. The global interpreter lock and the lack of an asynchronous programming model are becoming barriers to accommodating the numbers of users typical of today's mobile as well as web worlds. In this talk I cover the transition of a back-end service to Scala and the changes associated with it. The improved performance and cost savings of the Scala implementation free up resources that could be better leveraged elsewhere.
V8 is Google's open source JavaScript engine that is used in Chrome and Node.js. It uses several optimization techniques like hidden classes, inline caching, and TurboFan to improve JavaScript performance. V8 first parses JavaScript into an AST, then compiles it into bytecode which is executed by the Ignition bytecode interpreter or optimized by TurboFan into machine code using techniques like hidden classes to optimize property access and inline caching to optimize function calls.
Using the Tooling API to Generate Apex SOAP Web Service ClientsDaniel Ballinger

The document discusses using Ajax and XML to build a weather widget. It explains the basic anatomy of an Ajax pattern involving a trigger, operation, and update. It then covers using the XMLHttpRequest object to make requests to a weather.com REST service and parse the XML response to display weather data.
Cache is King: Get the Most Bang for Your Buck From RubyMolly Struve
Sometimes your fastest queries can cause the most problems. I will take you beyond the slow query optimization and instead zero in on the performance impacts surrounding the quantity of your datastore hits. Using real world examples dealing with datastores such as Elasticsearch, MySQL, and Redis, I will demonstrate how many fast queries can wreak just as much havoc as a few big slow ones. With each example I will make use of the simple tools available in Ruby to decrease and eliminate the need for these fast and seemingly innocuous datastore hits.
HyperBatch is a new interface that allows batch jobs in Salesforce to run much faster by processing jobs in parallel instead of serially. Using HyperBatch, three example batch jobs that previously took a total of 88 minutes to complete were able to finish in just 4 minutes, an over 90% reduction. HyperBatch leverages browser orchestration, parallel remote actions, and JavaScript polling to chunk batch jobs into parallel executions that can complete over 20 times faster than the traditional Apex Database.Batchable interface.

Device-specific Clang Tooling for Embedded SystemsemBO_Conference
This document discusses using Clang tooling to refactor raw memory accesses in embedded C code to be type-safe and readable. It involves parsing a CMSIS SVD file to get the device memory map, writing AST matchers to find raw memory accesses, and generating fix-its to refactor the accesses. The tool is implemented as a Clang-tidy check for static analysis and refactoring at compile-time. Challenges include handling cases where register offsets cannot be evaluated statically and designing the tools to work with existing code patterns.
The document discusses several technical topics related to threads, performance, and craftsmanship. It provides details on the CAP theorem, space-time tradeoffs, and balancing throughput versus latency. It also examines the differences between heavy, medium, and light weight processes and threads. The document summarizes the key components of Java threads, discusses when threads should wait, and provides tips on getting promoted such as solving your boss's biggest challenges. It encourages developing simpler code, using parallel I/O operations, and not assuming that older technologies are not still useful.
This document discusses common security anti-patterns and cargo cult programming practices related to cryptography. It describes how using cryptographic primitives incorrectly or for the wrong purposes can significantly weaken security. For example, using non-cryptographic random number generators, reusing initialization vectors, or rolling your own encryption when libraries are available. The document advocates identifying true security goals, using the correct cryptographic primitive, and relying on proven libraries instead of writing custom crypto code whenever possible.

Prisoner's Dilemma and Service-oriented ArchitecturesDerrick Isaacson
Moving to a service-oriented architecture solves problems like fate sharing, coupling, and scaling. It also brings the complexity of a “partially up/partially down” system, with nodes regularly getting sick or otherwise partitioned.
Learn what the Prisoner’s Dilemma teaches us about building a partition tolerant system. Hear how the CAP theorem (consistency, availability, and partition tolerance) helps the architect make intelligent trade-offs. See real examples from Google, Amazon, and others of building highly available distributed systems.
This document summarizes REST (Representational State Transfer) and some of its key principles. It discusses the simplicity of single component services, distributed system architectures like RPC and distributed file/data stores. It also covers the uniform interface of REST, including methods, headers, status codes, content negotiation, and authentication. The document notes that REST emphasizes a uniform interface between components to distinguish it from other network-based styles.
See common anti-patterns for securing web applications and how to correct them. Learn how to differentiate between authentication, authorization, secrecy, integrity, non-repudiation, and other security goals.
Examples include how:
* a theoretical "secret" banking request is corrupted to pad an attacker's bank account,
* an insecure "session" authentication token is attacked, and
* a "random" XSRF value gives a false sense of security.
Correct principles and patterns are analyzed and compared with common incorrect ones.
Presented at OpenWest 2014
It has been observed that "A distributed system is at best a necessary evil, evil because of the extra complexity." Multiple nodes computing on inconsistent state with regular communication failures present entirely different challenges than those computer science students face in the classroom writing DFS algorithms. The past 30 years have seen some interesting theories and architectures to deal with these complexities in what we now call "cloud computing". Some researchers worked on "distributed memory" and others built "remote procedure calls". More commercially successful architectures of late have popularized ideas like the CAP theorem, distributed caches, and REST.
Using examples from companies like Amazon and Google this presentation walks through some practical tips to evolve your service-oriented architecture. Google's Chubby service demonstrates how you can take advantage of CAP's "best effort availability" options and Amazon's "best effort consistency" services show the other end of the spectrum. Practical lessons learned from Lucidchart's forays into SOA share insight through quantitative analyses on how to make your system highly available.

The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.

HCL Notes und Domino Lizenzkostenreduzierung in der Welt von DLAUpanagenda
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-und-domino-lizenzkostenreduzierung-in-der-welt-von-dlau/
DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen!
Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.
Diese Themen werden behandelt
- Reduzierung der Lizenzkosten durch Auffinden und Beheben von Fehlkonfigurationen und überflüssigen Konten
- Wie funktionieren CCB- und CCX-Lizenzen wirklich?
- Verstehen des DLAU-Tools und wie man es am besten nutzt
- Tipps für häufige Problembereiche, wie z. B. Team-Postfächer, Funktions-/Testbenutzer usw.
- Praxisbeispiele und Best Practices zum sofortigen Umsetzen
10. Don’t DDOS Yourself
• Use RESTful principles for correct status codes
(5xx vs 4xx) so clients know when to rety.
• Use correct headers:
• Retry-After: 120
12. Typed (JavaScript) Code Pays
Off
• Static type checking
• Unused value detection
• Dead code removal
• Syntax validation
• Style warnings
• JS pitfalls detection
13. Beware ORMs
Anorm is Not an Object Relational Mapper
What does a framework really need?
• Paremeterized queries
• Simpler API than JDBC
• Control over your queries

Scala & Play Framework
See AWS Docs & RFC 2104Used by the Play Framework, AWS, IPsec, TLS, and many other protocols, services, and frameworks.
Shard everything. Dbs are almost impossible to scale horizontally when not sharded. You may be going along fine, then one day "bang" you hit a tipping point and your db no longer can handle the load. Sharding gives you options.Pick your shard keys very carefully. Once you have chosen a shard key, it is very difficult to change (sharding on documentid in mongo is an example of where we messed that up and it is killing us right now)
Single page apps make lots of ajax calls. Make sure those calls are done in a way such that if a failure occurs, it doesn't turn around and try again immediately and indefinitely (don't DDOS yourself with your own javascript client).
Actors are a great way to introduce concurrency without introducing tons of bugs. We added a lot of concurrency to the PDF service and haven't had concurrency related issues (not typically the case when adding concurrency by managing threads).
Typed client code pays off (google closure).
Beware of ORMs generally. They tend to create terrible queries that do lots of joins which should be avoided whenever possible. Tools like Anorm allow us to write our own queries. SQL is a domain specific language: do we really need a domain specific language as an abstraction over SQL?
Beware of MVC frameworks that do a lot of magic: while they reduce the amount of code to be written, they can introduce security holes (form binds to a model that saves to the db, but a malicious user can add param to the form, post it and modify other fields in the table that you didn't intend the user to be able to modify)
