I’ve been looking for an online casino that actually offers something special for players from Canada. Most places just feel generic and don’t seem to care much about regional bonuses. Have you come across any sites that really stand out for Canadian users?

Inventory API question
by Austin Kuo
I was creating 2 different resource types with the same http client at the
same time.
But one succeed, the other failed with the response 400 and body:
{
"errorMsg" : "The transaction has already been closed"
}
Is it not allowed to do so?

need a briefing on what the hawkular agent is now doing with respect to inventory
by John Mazzitelli
Joel,
Now that the new inventory-into-metrics is in master and released, I need to know what you did :-D I suspect others will want to know what you did too.
Is it possible for you to write something up or have a 15-minute Blue Jeans session to discuss how inventory is stored in H-Metrics?
I am going to need to know this because I have to implement it in GoLang for HOSA, unless you want to do it :)

BTM agent relationship with Hawkular agent
by Gary Brown
Hi
On the team call just now, Heiko raised a question about whether the BTM agent could work with the Hawkular agent. So thought I would start this discussion thread to see what the potential options are.
I currently see two issues:
1) The BTM agent must be configured on the jvm command line as a "-javaagent" to install ByteMan for instrumentation purposes. This is instantiated before the JBoss modules (and therefore subsystems etc) are initialised.
2) The hawkular agent won't necessarily be installed in all monitored servers, and instead remotely monitor some. The BTM agent would need to be installed in all servers where business transactions are executing.
One type of integration that may be possible is in terms of delivering the captured business transaction information to the backend? i.e. the BTM agent locally reports it to the Hawkular agent as a relay?
Thoughts?
Regards
Gary

logging in java agents is not trivial in WildFly / EAP
by John Mazzitelli
<tl;dr>
No matter if a java agent uses JBoss Logging or simply relies on the JRE's own Java logging, it still won't work in WildFly/EAP unless you set additional things to environment variables in standalone.conf. So no matter what logging is used, this means problems still need to be overcome when putting java agents in host controllers for EAP 7.0 domain mode.
</tl;dr>
I am looking at how Java Agents should log messages when attached to WildFly or EAP. I want to see if there is a way to implement a Java Agent and NOT have to set any special JAVA_OPTS values to pass to the VM to get it to work.
Turns out, it is not a trivial issue.
I wrote a silly little test agent [1] just to see what would happen if it simply logs a message using *java* logging and spins a thread logging a message every second again using *java* logging. So, no extra third party logging libraries, just using java.util.logging classes that are in the JRE already.
Adding just -javaagent to JAVA_OPTS (in standalone.conf, add something like "-javaagent:/where/it/is/ja.jar=foo=bar") is no good, the server bombs with this error, presumably because my agent already started logging using java logger:
Caused by: java.util.concurrent.ExecutionException: java.lang.IllegalStateException: WFLYLOG0078: The logging subsystem requires the log manager to be org.jboss.logmanager.LogManager. The subsystem has not be initialized and cannot be used. To use JBoss Log Manager you must add the system property "java.util.logging.manager" and set it to "org.jboss.logmanager.LogManager"
Well, catch-22, because if I set java.util.logging.manager=org.jboss.logmanager.LogManager in JAVA_OPTS, this happens when the test agent tries to log:
Could not load Logmanager "org.jboss.logmanager.LogManager"
java.lang.ClassNotFoundException: org.jboss.logmanager.LogManager
which then falls back to java logging, which then causes the server to bomb again because it wants JBoss Logging.
If I set this in standalone.conf:
JBOSS_MODULES_SYSTEM_PKGS="org.jboss.byteman,org.jboss.logmanager"
the java agent still gets this error:
Could not load Logmanager "org.jboss.logmanager.LogManager"
java.lang.ClassNotFoundException: org.jboss.logmanager.LogManager
which is then followed by jboss modules error which causes the server to again to fail to start:
WARNING: Failed to load the specified log manager class org.jboss.logmanager.LogManager
Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/logmanager/Level
...
at org.jboss.modules.Module.run(Module.java:320)
The ONLY way to get the server to start properly with this java agent installed (EVEN WITH the agent using ONLY java logging), you have to do all of the above plus add this to JAVA_OPTS:
-Xbootclasspath/p:$JBOSS_HOME/modules/system/layers/base/org/jboss/logmanager/main/jboss-logmanager-2.0.4.Final.jar
So, in short, you need to add "-Djava.util.logging.manager=org.jboss.logmanager.LogManager" to JAVA_OPTS, you need to add ",org.jboss.logmanager" to JBOSS_MODULES_SYSTEM_PKGS, and you need to add that -Xbootclasspath to JAVA_OPTS just to get a javaagent to work even if the javaagent simply uses nothing more than standard java logging.

Are Live Casino Games Popular Among Pakistani Players?
by Kyle Linel
In recent years, live casino games have seen a significant rise in popularity worldwide, and Pakistan is no exception. With advancements in technology, players in Pakistan are increasingly opting for live dealer games over traditional online casino games in https://1wincasinoinpakistan.com/ . But what makes these games so appealing, and why are they gaining traction among Pakistani gamblers?
The Appeal of Live Casino Games
Live casino games offer a unique blend of online convenience and the immersive experience of a physical casino. Unlike standard online games, which rely on random number generators (RNGs), live casino games feature real dealers who interact with players in real-time. This creates a more authentic atmosphere and enhances the overall gaming experience. Whether it’s live blackjack, live roulette, or live baccarat, these games allow players to experience the thrill of a land-based casino from the comfort of their homes.
Factors Contributing to Popularity in Pakistan
Real-Time Interaction: One of the main reasons live casino games are gaining popularity in Pakistan is the real-time interaction with dealers. This human element offers a level of transparency and trustworthiness that appeals to many players who are wary of RNG-based games.
Convenience: Live dealer games can be played from any location with a reliable internet connection, making it convenient for players in Pakistan to enjoy their favorite games anytime, anywhere. The mobile-friendly nature of many live casino platforms also allows for a more flexible gaming experience.
Authentic Casino Experience: For many Pakistani players, live casino games replicate the atmosphere of a physical casino. The dealers are often professional and knowledgeable, enhancing the sense of excitement. This authentic experience is hard to beat and has helped live games stand out from traditional online offerings.
Access to International Games: Online casinos offering live dealer games often feature games hosted by international casinos, bringing global casino options to Pakistani players. This increases the variety of games available, allowing players to explore a wider selection than they would find at local brick-and-mortar establishments.
Challenges and Considerations
While live casino games are growing in popularity, there are a few challenges that Pakistani players may face. For instance, the internet connection needs to be fast and stable to ensure smooth gameplay without interruptions. Additionally, the legal landscape for online gambling in Pakistan remains unclear, and players must ensure they are gambling on licensed and reputable platforms to avoid any potential issues.
Conclusion
Live casino games are indeed becoming increasingly popular among Pakistani players due to their immersive, interactive, and authentic experience. The ability to play in real-time with professional dealers and the convenience of accessing these games from home makes them a favorite for many. However, players must remain cautious and ensure they are playing on safe and legal platforms. As the online gambling industry continues to evolve, live casino games are likely to maintain their popularity in Pakistan for years to come.
