You may have heard that Node.js as JavaScript for the server-side and you may be wondering why anyone would want that!. Or maybe you know exactly what Node.js is, but aren’t sure when or why to use it.
This month Coffee@DBG comes up with “Step into the Node JS Express” to answer all your questions on Node.JS. If you are enthusiastic to know more about it and why it’s making waves in the community, join it now before the seats get filled.
Coffee @ DBG is a Rendezvous of open interactive discussions in technology, where enthusiasts from different companies of Technopark have a get-together to discuss and share their knowledge over a cup of Coffee at DBG.
Coffee@DBG has been the most popular tech event in Technopark happening every month on first Wednesdays which will also provide a platform for programmers to get free consultation on problems they are facing in real work.
First ever talk about Node.JS in Kerala by its early adopters.
You probably know the mantra that allocation is cheap. It usually is true, but devil is in the details. In your use case object allocation may impact processor caches evicting important data; burn CPU on executing constructor code; impact rates of object promotion to old generation and most importantly increase frequency of stop the word young gen pauses.
This presentation is for you if you are working on a Java based services that need to handle more and more traffic. As number of transactions per second rises you might hit performance wall that are young generation gc stopping whole application for precious milliseconds.
This presentation focuses on optimising object creation rate when dealing with seemingly mundane tasks. I will show few examples of surprising places in JDK and other libraries where garbage is created. I will explain how New Gen GC collection works and what costs are related to it. We will se escape analysis in action. Finally we will conclude that controlling allocation is the concern of library writers so that we can easily implement performant code without doing premature optimisations.
2012 yılında, o sırada gerçekleştireceğiniz bir projede hangi dili kullanacağımız konusunda kararsız kalmıştık. Ben Python yanlısıydım ve görüşümü desteklemek için Java ve Python'u yapısal ve performans olarak kıyaslayan nu sunumu hazırlamıştım. Benzer kararsızlıklar yaşayanlara faydalı olmasını umuyorum.

Everything you wanted to know about writing async, concurrent http apps in java Baruch Sadogursky
As presented at CodeMotion Tel Aviv:
Facing tens of millions of clients continuously downloading binaries from its repositories, JFrog decided to offer an OSS client that natively supports these downloads. This session shares the main challenges of developing a highly concurrent, resumable, async download library on top of an Apache HTTP client. It also covers other libraries JFrog tested and why it decided to reinvent the wheel. Consider yourself forewarned: lots of HTTP internals, NIO, and concurrency ahead!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. Handler architecture
based on Netty 4
Request
(Inbound)
Response
(Outbound)
ServerSsl
Aggregates
HttpObjects (headers
and contents) to make
Xitrum HandlerEnv; all
Xitrum handlers work
with HandlerEnv
Request2Env
ChunkedWrite
NoPipelining
Env2Response
SetCORS
BasicAuth
OPTIONSResponse
PublicFileServer
FixiOS6SafariPOST
PublicResourceServer
Serves resource files in
classpath (and JAR files)
HttpResponseEncoder
BaseUrlRemover
Serves static files in
public directory
HttpRequestDecoder
XSendFile
UriParser
XSendResource
MethodOverrider
Selects and calls action
(see next slide)
Converts Xitrum
HandlerEnv to Netty’s
FullHttpResponse
Shortcut may happen
(action will not be
called at Dispatcher)
ResponseCacher
Dispatcher
BadClientSilencer
Catches all errors
These 4 handlers are
provided by Netty; the
others are created by
Xitrum
Action#execute
respondText, respondVi
ew,
respondFile,
respondBinary etc.
3. Routing
• Route collection:
At startup, Xitrum automatically collects all
routes specified by annotations
@GET(“hello”), @POST(“hi”) etc.
• Routing:
At “Dispatcher” (see previous slide), the an
instance of the specified action class is created
and its “execute” method is called.
