IBM MQ and Kafka, what is the difference?David Ware
Message queueing solutions used to be the one general purpose tool used for all asynchronous application patterns, then along came event streaming as an application model. To support this effectively needed a whole new approach to how messages are handled by the messaging technology. Now the tables are turned and many are wondering if an event streaming solution can be used for all their asynchronous application patterns from now on. But just as message queueing solutions work in a way to optimize for their core use cases, so do event streaming solutions, and these behaviors directly affect the applications that use them. This session picks IBM MQ and Kafka to look at how they compare and, more importantly, differ in their behavior so that you can decide which application scenarios are best suited by each. Spoiler -they're both good in their own way!

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

ZF: Push Notifications
By Mike Willbanks
Software Engineering Manager
CaringBridge
2. About Mike…
• Software Engineering Manager at CaringBridge
• Open Source Contributor
• Where you can find me:
Twitter: mwillbanks
G+: Mike Willbanks
IRC (freenode): lubs
Blog: http://blog.digitalstruct.com
2
3. Agenda
• Overview of Push Notifications
• Overview of Zend_Mobile [_Push]
Not currently implemented in ZF 1.x; maybe ZF 1.12.
• Android Push Notifications (C2DM)
• Apple Push Notifications (APNS)
• Microsoft Push Notifications
• BlackBerry Push Notifications
• Questions
Although you can bring them up at anytime!
3
5. What Are They
• Push Notifications…
Are a message pushed to a central location and delivered to you.
Are (often) the same thing at a pub/sub model.
In the Mobile Space…
• These messages often contain other technologies such as alerts, tiles,
or raw data.
5
7. Benefits of Push Notifications
The benefits of push notifications are numerous; the
question is if you have an app and you are running services
to poll; why would you do such a thing!
10. Battery Life
• Push notification services for mobile are highly efficient; it
runs in the device background and enables your application
to receive the message.
• The other part of this; if you implemented it otherwise you
would be polling. This not only wastes precious battery but
also wastes their bandwidth.
NOTE: This is not always true; if you are sending data to the phone
more often than a poll would do in 15 minutes; you are better off
implementing polling.
10
12. Delivery
• When you poll; things are generally 15+ minutes out to save
on battery. In a push notification these happen almost
instantly.
We’ve generally seen within 1-3s between sending a push
notification to seeing it arrive on the device.
• Additionally; push notifications can be sent to the device
even if it is offline or turned off.
• However, not all messages are guaranteed for delivery
You may hit quotas
Some notification servers only allow a single message to be in
queue at 1 time (some group by collapse key), and others remove
duplicates.
12
18. Overview of Zend_Mobile_Push
• Created Zend_Mobile component in November because I
was irritated with the other libraries that currently existed.
• More fluid way of sending push notifications.
• Requires Zend Framework 1.x
Hopefully will make it into the ZF 1.12 release planned within the
next month or two.
• Handles sending push notifications to 3 systems
APNS, C2DM and MPNS
• Library is located in my GitHub account
https://github.com/mwillbanks/Zend_Mobile
18
19. Setting up the Library
• Git clone the package somewhere you would like it to live.
• Adjust your include_path (likely set in index.php)
• You’re ready to rock!
• Hopefully; in the future you won’t have to do anything
19
21. Understanding C2DM
• It allows third-party application servers to send lightweight
messages to their Android applications.
• C2DM makes no guarantees about delivery or the order of
messages.
• An application on an Android device doesn’t need to be
running to receive messages.
• It does not provide any built-in user interface or other
handling for message data.
• It requires devices running Android 2.2 or higher that also have
the Market application installed.
• It uses an existing connection for Google services (Through the
Google Market)
21
22. Registering for C2DM
• First things first – you must sign up to actually utilize C2DM
http://code.google.com/android/c2dm/signup.html
C2DM only works on Android w/ Google Market
• Basically excludes: Amazon Kindle Fire.
22
24. How the Application Works
• We must update the Manifest file to state additional
permissions.
• We will then create a broadcast receiver that will handle
the messages and registration.
24
26. Handling the Registration (or Unregistering)
• Registration / Registration Updates and Unregistering.
• Registration is generally on app start up.
• Be nice and allow your users to unregister from the push
notification service
26
27. Example Receiver
More at: http://bit.ly/bxOoMO towards end of article.
27
28. Implementing a Server
• Some limitations
200K messages per day by default; use them wisely however you
may request more.
1K message payload maximum.
You must implement incremental back off.
28
32. Understanding APNS
• The maximum size allowed for a notification payload is 256
bytes.
• It allows third-party application servers to send lightweight
messages to their iPhone/iPad applications.
• Apple makes no guarantees about delivery or the order of
messages.
• An application on an iPhone/iPad device doesn’t need to be
running to receive messages.
• Message adheres to strict JSON but is abstracted away for us in
how we will be using it today.
• Messages should be sent in batches.
• A feedback service must be listened to.
32
33. Preparing to Implement Apple Push Notifications
• You must create a SSL certificate and key from the
provisioning portal
• After this is completed the provisioning profile will need to
be utilized for the application.
• Lastly, you will need to install the certificate and key on the
server.
In this case; you will be making a pem certificate.
33
35. How the Application Works
• Registration
The application calls the registerForRemoteNotificationTypes:
method.
The delegate implements the
application:didRegisterForRemoteNotificationsWithDeviceToken:
method to receive the device token.
It passes the device token to its provider as a non-object, binary
value.
• Notification
By default this just works based on the payload; for syncing you
would implement this on the launch.

38. Implementing the Server
• Some Limitations
Don’t send too many through at a time; meaning around 100K
• Every once in a while use a usleep
Max payload is 256 bytes

42. Microsoft Push Notifications
Well, I am not certain if they will find the market share yet
but hey; some people need to build apps for it!
43. Understanding MPNS
• It allows third-party application servers to send lightweight
messages to their Windows Mobile applications.
• Microsoft makes no guarantees about delivery or the order of
messages. (See a pattern yet?)
• 3 types of messages: Tile, Toast or Raw
• Limitations:
One push channel per app, 30 push channels per device, additional
adherence in order to send messages
3K Payload, 1K Header

44. Preparing to Implement MPNS
• Upload a TLS certificate to Windows Marketplace
The Key-Usage value of the TLS certificate must be set to include
client authentication.
The Root Certificate Authority (CA) of the certificate must be one
of the CAs listed at: SSL Root Certificates for Windows Phone.
Stays authenticated for 4 months.
Set Service Name to the Common Name (CN) found in the
certificate's Subject value.
Install the TLS certificate on your web service and enable HTTP
client authentication.

51. BlackBerry Push Notifications
Are these even going to be needed in another year?
I keep thinking about adding them in; but I am completely
unsure if they work…
52. Understanding BlackBerry Push
• It allows third-party application servers to send lightweight
messages to their BlackBerry applications.
• Allows a whopping 8K or the payload
• Uses WAP PAP 2.2 as the protocol
• Mileage may vary…
52
54. Application Code
• They have a “Sample” but it is deep within their Push SDK.
Many of which are pre-compiled.
Documentation is hard to follow and the sample isn’t exactly
straight forward:
• Install the SDK then go to BPSS/pushsdk-low-level/sample-push-
enabled-app/ and unzip sample-push-enabled-app-1.1.0.16-sources.jar
Since I do not touch blackberry; or have the desire, I would ensure
the library works for people that want it; just help me test it!

55. Preparing to Implement
• You need to register with BlackBerry and have all of the
application details ready to go:

• Download the PHP library:
Updated to be OO; non-tested and a bit sloppy:

56. Implementing BB Push w/ PHP
• Be aware… this code is highly alpha – never been tested.
• If you do use BlackBerry push messages; please connect
with me so that I can include this in the Zend_Mobile_Push
component.

58. Next steps
• ZF 2
If / when this library makes it into ZF 1.x; I will be working on it
for 2.x. My first focus is ensuring it’s successful addition to ZF 1.x.
I have some code for the 2.x version but some minor refactoring is
due to fit the new model.
• BlackBerry
Who knows where they will end up. All I know is that developing
for it seems painful and the documentation is certainly not what I
would like to see.
There is a large need for a quality implementation but at the same
point developers are not highly interested in their platform.
