Simple tweaks to get the most out of your jvmJamie Coleman
Many developers don’t think about the JVM level when creating applications. It is something that just simply works. Now more applications are becoming cloud-native and we have JVM’s running in every microservice container, each performance gain can have massive benefits when scaled up. Some tweaks are very easy to implement and can have huge impacts on start-up time and performance of your applications. This talk will go through all the different JVM options and give you some easy and simple advice on how to get the most out of your JVM to save not only money but also energy on the cloud.
J1 2015 "Debugging Java Apps in Containers: No Heavy Welding Gear Required"Daniel Bryant
It’s easy to get seduced by being able to quickly deploy and scale applications by using containers. However, when things inevitably go wrong, how do you debug your application? This session covers various pro bug hunting tips and tricks. It shows live demos of tools such as the Docker stats API, Docker exec (and top, vmstat, and netstat), and how to use the ELK stack for centralized logging. It also dives into other more sophisticated tools that operate at the application and (micro)service layer, such as Twitter’s Zipkin tracing app, Spring Boot’s Actuator, and DropWizard’s Metrics library. Keep those container-based nightmares away by ensuring that when the worst does happen, you have the tools, info, and experience to debug containerized applications.

Bulding a reactive game engine with Spring 5 & CouchbaseAlex Derkach
A social game, by it’s nature can spread very quickly to a large user audience. Since a game is typically interactive, the speed of retrieving information needed for the user’s interactions with the system is critical. Applications which exclusively rely on synchronous data access, very often hit a scalability wall, when things get slow and their thread pools are exhausted. New paradigms like reactive programming alleviate this and provide extensive tool sets to deal with the ever growing demands of web applications.
This talk:
– Describes why Couchbase is the most appropriate solution for many video game and gaming use cases.
– Shows how to build scalable and reactive applications by making use of the Couchbase Java SDK 2.x, RxJava library and Spring Framework 5.
當線上運作環境發生問題時,如何在最短時間找出問題核心?我們使用 counter 這個工具來解決。Counter 是在程式裡的一行程式碼,用來記錄感興趣的事件。本演講包含以下內容:Golang counter 程式碼範例,後台系統架構,線上 dashboard,以及如何使用 counter 來偵錯,甚至可以一路追至某一行程式碼。另外,本演講會提及幾個有趣的應用:counter 如何協助定期伺服器更新,如何使用 counter 協助 autoscaling,以及未來的應用。
When production alert triggers, how to identify the root cause within the shortest amount of time? We solve the problem by counter, a line of code inserted by developer to count interesting events. In this talk, we'll cover the following topics: 1) how counter looks like in Golang production code, 2) our counter pipeline, 3) service dashboard with counters, 4) how to use counter to find production issues all the way to certain line of code. We'll also cover a few interesting counter use-cases, including: 1) How counter helps our weekly server upgrade, 2) Use counter for autoscaling, and 3) case-studies to demonstrate what counter can do when outages happen.

Lucio Grenzi - Building serverless applications on the Apache OpenWhisk platf...Codemotion
Apache OpenWhisk provides a powerful and flexible environment for deploying cloud-native applications driven by data, message, and API call events. We will show how and why we integrated Apache OpenWhisk and GitHub to make deployment as easy and transparent as `git push`. We will also discuss the benefit of using an open source cloud platform and explain how serverless allows developers to focus on writing value-adding code.
Apache Lucene is the de-facto standard open source library for Java developers to implement full-text-search capabilities.
While it’s thriving in its field, it is rarely mentioned in the scope of Java EE development.
In this talk we will see for which features many developers love Lucene, make some concrete examples of common problems it elegantly solves, and see some best practices about using it in a Java EE stack.
Finally we'll see how some popular OSS projects such as Hibernate ORM (JPA provider), WildFly (Java EE runtime) and Infinispan (in-memory datagrid, JCache implementor) actually provide great Lucene integration capabilities.

Full stack development with node and NoSQL - All Things Open - October 2017Matthew Groves
What is different about this generation of web applications? A solid development approach must consider latency, throughput, and interactivity demanded by users users across mobile devices, web browsers, and IoT. These applications often use NoSQL to support a flexible data model and easy scalability required for modern development.
A full stack application (composed of Couchbase, WebAPI, Angular2, and ASP.NET/ASP.NET Core) will be demonstrated in this session. The individual parts of a stack may vary, but the overall design is the focus.
The new GraalVM from Oracle supports multiple language including JavaScript, Python, Ruby, R, C++ as well as Java and other JVM languages. This opens up interesting possibilities for polygot enterprise applications. Now you can use a Node library in a Java application or call an R statistical function from an EJB. Previously, this type of integration was extremely challenging. This session will provide recipes to get up and running along with best practices and some cool demos.

Monitoring Big Data Systems Done "The Simple Way" - Demi Ben-Ari - Codemotion...Codemotion
Once you start working with Big Data systems, you discover a whole bunch of problems you won’t find in monolithic systems. Monitoring all of the components becomes a big data problem itself. In the talk, we’ll mention all of the aspects that you should take into consideration when monitoring a distributed system using tools like Web Services, Spark, Cassandra, MongoDB, AWS. Not only the tools, what should you monitor about the actual data that flows in the system? We’ll cover the simplest solution with your day to day open source tools, the surprising thing, that it comes not from an Ops Guy.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

Agenda
● Why Do We Need Offline-First Design?
● Browser APIs Essential For Reliable Web
Apps.
● The Most Common UI/UX Patterns.
● Offline Storage With Replication to a Server.
● Challenges when you build Offline-First Apps.
11. 11
Web has evolved and ready to compete with native apps
Pros (compare to native apps):
● No installation.
● It may take less space.
● Web apps are way more secure

HTML5 Application Cache
Pros:
Extremely easy to use.
Older browsers support it, only option in IE 10 & IE 11.
Cons:
Can be served over insecure HTTP.
Lacks flexibility.
Will be removed soon in new browsers.

Service Worker Install Event
const cacheCriticals = () => {
return caches.open(CACHE_NAME).then(cache => {
// important, but not critical
cache.addAll(resourcesToCache);
// critical resources
return cache.addAll(criticalResources);
});
};
self.addEventListener('install', function (installEvent) {
installEvent.waitUntil(cacheCriticals());
});
21. 21
Service Worker Activate Event
function cleanup(cacheNames) {
return Promise.all(
cacheNames.filter(function (cacheName) {
return cacheName !== CACHE_NAME;
}).map(function (cacheName) {
return caches.delete(cacheName);
})
);
}
self.addEventListener('activate', function(event) {
event.waitUntil(caches.keys().then(cleanup));
});
*Old service worker is paused at that moment. Fetch requests will be added to queue..
22. 22
Service Worker Fetch Event
self.addEventListener('fetch', function(event) {
// magic goes here
});
*The request is attended by the most specific SW only.
23. 23
Service Worker Fetch Event
self.addEventListener('fetch', function(event) {
event.respondWith(fetch(event.request));
});

Workbox
Offline Caching:
● Cache only
● Cache first, falling back to network
● Cache, with network update
● Network only
● Network first, falling back to cache
Offline Analytics:
Workbox can collect user analytics while offline.
28. 28
Workbox
You can integrate it with:
Or use it directly in the service worker:
//synchronously imports scripts into the worker's scope
importScripts('/node_modules/workbox-sw/build/workbox-sw.vX.X.X.prod.js');
const workboxSW = new WorkboxSW();
const networkFirst = workboxSW.strategies.networkFirst();
workboxSW.router.registerRoute('/schedule', networkFirst);

BackgroundSync DEMO
Service Worker Background Sync
// sync will fire when the user agent believes the user has connectivity
self.addEventListener('sync', function(event) {
if (event.tag === ‘anyTag’) event.waitUntil(doWhatYouWant());
});
Finally, we have a better option than WindowEventHandlers.onbeforeunload

Browser Storage APIs
Cache API (part of Service Worker). - use it for URL addressable resources.
IndexedDB - use it for all other data. (Also, exist polyfills with fallback to Web
SQL).

Space available to origin is shared between all forms of storage above.
There is no standard way to check quota. We have two
experimental APIs: Quota Management API and Storage
Manager API.

Be Aware of Cache Eviction in Browsers
*If app is not installed by user (Chrome, FF) or don’t have
high engagement.
Chrome LRU once Chrome runs out of
space
Firefox LRU if the whole disk gets full
Safari & Edge No cache eviction
!! It includes Indexed DB and Cache API.

navigator.storage.persist().then(function(isPersistent) {

● Try to provide offline by default if your app doesn't
require much data.
● Treat a connection to the internet as an enhancement
instead of a dependency
● Use optimistic UI approach if possible.
● User must be properly notified about app state.
● Use save for offline button
● Precache things that needed with high probability
offline especially if they are small
Core ideas
39. 39
Connection is enhancement not a dependency
You can create new google doc while you offline.
Once we connect to internet it will be synced.
40. 40
Use optimistic ui approach if possible
avoid that approach
if possible
If we offline, sync that action later.
42. 42
Use save for offline button
Especially important
approach for content
oriented applications
like:
● Spotify
● Google maps
● Web readers
● e.t.c
43. 43
Cache things automatically
● Do you users often use that
feature?
● Can it be useful offline?
● Is it lightweight?
● Is it not sensitive data?
If answer yes for all
Pre-cache it without asking.

PouchDB + CouchDB
CouchDB is was designed from the bottom-up to
enable easy synchronization between databases.
{
"_id": "any_string",
"_rev": "1-bea5fa18e06522d12026f4aee6b15ee4"
"name": "John",
...
}
50. 50
PouchDB + CouchDB
Pros:
● Production ready. Well tested
● Nice documentation.
● Wide browser support.
Cons
● You are tight to a specific DB which supports its sync
protocol on backend.
● Poor automatic conflict resolution*
● Not good for real time apps.
*The winner is the version with the longest revision history
And in case of a tie, the winner is the revision with the lexicographically highest
revision ID; e.g. "12-F4B2..." beats "12-42AA..."

More about CRDT
Well known CRDTs
● G-Counter (Grow-only Counter)
● PN-Counter (Positive-Negative Counter)
● G-Set (Grow-only Set, which only allows adding)
● 2P-Set (Two-Phase Set, remove-wins" set)
● LWW-Element-Set (Last-Write-Wins-Element-Set)
● e.t.c
CRDT provides strong eventual consistency (SEC)
It means that if all nodes get all updates in whatever order they will come to
the same state. If you use inappropriate type you may get messy state, although it will be
consistent across app.
59. 59
CRDT is not a silver bullet
Cannot model every data type..
60. 60
Swarm.js
Pros
● Real time replication
● Automatic conflict resolution
● Need little data to transfer (CmRDT)
Cons
● It is kind of research project
● Almost no documentation
● Vague future
61. 61
Logux
Pros
● In active development
● Very flexible
● Redux API
● Foundation for CRDT
Cons
● Very young project
Library inspired by Redux and Swarm.js
62. 62
Gun.js
Pros
● In active development
● With real time in mind
● Looks like best open source solution
● Integrates with different Backend DBs
Cons
● Not mature enough
64. 64
- Some useful API still not standardized
- Find security/convenience ballance.
- Handling multiple users on one machine.
- Educate through UI users about what is working offline
- Wise Caching. (Do not force user to download whole
site on first visit.)
- Mobile traffic costs a lot in some places.
- Data synchronization tools is quite immature.
- New auto testing challenges (Panic Server)
