hops | Universal Development Environment | Frontend Framework library

The predicate getDataFromCache(StringAddress,Cache,Data,HopsNum,directMap,BitsNum) should succeed when the Data is successfully retrieved from the Cache (cache hit) and the HopsNum represents the number of hops required to access the data from the cache which can differ according to direct map cache mapping technique such that: • StringAddress is a string of the binary number which represents the address of the data you are required to address and it is six binary bits. • Cache is the cache using the representation discussed previously . • Data is the data retrieved from cache when cache hit occurs. • HopsNum the number of hops required to access the data from the cache. • BitsNum The BitsNum is the number of bits the index needs.

getDataFromCache is always giving me false although everythings seems working so I want someone to fix it

I'm trying to configure a simple network structure using Vagrant as depicted in the following figure:

As you can see I aim to simulate a hacker attack which goes from attacker through router and reaches victim, but that's not important for the problem I'm struggling with.

This is my Vagrantfile so far (VritualBox is used as provider):

I have a cluster of Artemis in Kubernetes with 3 group of master/slave:

I am doing some work on worm-attack detection in RPL. In RPL, the communication between the clients might be multiple hops, with the packets going through many nodes.

However, only the receiver gets a tcpip_event on reception of the packet. The nodes that the route passes through do not get this event. Is there any way to detect the packet on the intermediate nodes?

I have an architecture where I have multiple instances but I want to maximize cache hits.

Users are defined in groups and I want to make sure that all users that belong to the same group hit the same server as much as possible.

The application is fully stateless, but having users from the same group hitting the same server will dramatically increase performance and memory load on all instances.

When loading the main page I already know which server I would like to send this user to on the XHR call.

Using the ARRAffinity cookies are not really great is almost impossible in this scenario (cross domain, have to make server call first etc) and I would strongly prefer sending a hint myself through a custom header.

I'm trying manually to do some workarounds with deleting the cookies and assigning them, but it feels very hacky and I don't get it fully working yet. and it doesn't work for XHR calls.

Question:

Is it possible to direct to a specific instance through a header, url or domain instead of a cookie?

Notes

• Distributed cache does not work for me in this case. I need the performance of memory cache without extra network hops and serialization/deserialization.
• This seems to be possible with Application Gateway, but it seem to need a lot of extra infrastructure and moving parts while all my problems would be fixed by sending the "right" header.
• I could fix this by duplicating the web app in its entirety and assigning a different hostname. Also this feels like adding a lot of extra moving parts that can break. Also maintenance will be harder and more confusing, I loss autoscale, etc.
• Maybe this can be fixed easily by Kubenetes/Docker Swarm type of architecture (no experience), but as this is a large legacy project and I have a pretty strict deadline I am very cautious of making such a dramatic switch last minute.

I am setting up a cluster of Artemis in Kubernetes with 3 group of master/slave:

ping 8.8.8.8 -t 5 -c1 | awk '{if (/Time.*/) print $1,$2; else if (NR==1) print "from: " $3 " "}'

When i use this line the else if doesn't work, it basically prints from and the ip no matter what first, even before the if conditional. I want it print it only when the TTL is enough to reach the target (Or when there isn't a message involving Time to live exceeded)

This command is basically a traceroute written by me.

I don't know why the else if conditional doesn't work, i would love help.

The whole bash script:

Let's say that I have 3 ActiveMQ Artemis brokers in one cluster:

1. Broker_01
2. Broker_02
3. Broker_03

In a given point of time I have a number of consumers for each broker:

1. Broker_01 has 50 consumers
2. Broker_02 has 10 consumers
3. Broker_03 has 10 consumers

Let's assume at this given point of time there are 70 messages to be sent to a queue in this cluster.

We are expecting load balancing done by the cluster so that Broker_01 would receive 50 messages, Broker_02 10 messages, and Broker_03 also 10 messages, but currently we are experiencing that the 70 messages are distributed randomly through all the 3 brokers.

Is there any configuration I can do to distribute the messages based on the number of consumers in each broker?

I just read the documentation. So, as far as I understood, ActiveMQ does load balancing, based on round robin, if we configure cluster connection. Our broker.xml looks like this:

Currently the configuration to embed a specific visual through the JS powerbi-client does not allow passing in filters. See "Embed a report visual" for the configuration supported. Note that you are able to pass in filters at embed time for a report. See "Embed a report". Not being able to filter a visual at embed time results in 2 hops (once to load the visual with default filters, then another to load with expected filters).

Feature Request: I'd love for the feature to be added to filter at embed time for visuals like it exists for reports.

The way I do this now is hide the visual, embed it, set filters when loaded, then show it when rendered.
