In cosmos DB, one replica-set consists of 4 replicas. It has one leader and 3 followers (including a forwarder).

I assume that all updates go through the leader first and the leader is the first one to be updated when updates come in the replica-set.

If my assumption is correct, a reader does not have to read many replicas. It only needs to check the leaders in each replica-set to figure out latest updates.

For example, Cosmos DB documentation says that in case of eventual and consistent prefix consistency models, quorum reads is accessing one single replica. As far as I understand it, the single replica can be any replica in a region. But, if a reader needs to read a update from a replica, does it have to be a leader replica?

I am trying to install below two custom vm extensions in Azure VM. i) Dns forwarder - https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/demos/dns-forwarder/forwarderSetup.sh ii) crowd strike falcon sensor https://raw.githubusercontent.com/crowdstrike/falcon-linux-install-bash/main/falcon-linux-deploy.sh

Able to install the above extensions independantly one at a time, but unable to install both vm extensions sequentially one by one. Is there any way we can achieve this ? let me know.

Thanks, Kumar

How can I check proxy anonymities in Python?

I've tried searching this up but all I got that really made sense was this answer.

But I don't have the resources to host a "test site" to get the headers of the requests.

I've tried hosting my own site on localhost with Flask but my IP doesn't like being GET requested by random proxy servers.

I had an idea to use HttpBin's API but it ignores the Required Via and X-Forwarder-For request headers.

I could probbably use another API but I don't know about any others.

So, how can I check a http proxy's anonymity in Python?

We have a process that writes log lines to a log file. Every 15 min the entire log file is overwritten. If there are new lines, those are added. Old lines are retained.  

We want the Heavy Forwarder to send to Splunk only the new lines, even though the entire file has got overwritten. Is that possible?

We have a requirement where we need to forward only specific string logs to kibana endpoint/console. Currently we are getting pattern not match line where the matched string not found. How to ignore those logs not to send to forwarder and only send match logs.

I'm trying to add a trigger to a lambda function, using the UI, I'm able to select trigger type "Cloud Watch".

Browser (Chrome) network tab, reveals this function being called.

Looking through Datadog AWS integration documentation I found mention that AWS alarms can be streamed into Datadog. It's stated that you can choose two different methods how to send AWS CloudWatch alarms to the Datadog Event Stream right here in the Alarm collection section. But there is no further explanation on how to do that or what should be set upped to do that. Moreover, trying to google something like "Datadog aws alarm polling" gives you vague descriptions of some other functionalities but not the AWS CloudWatch alarms.

My question is is it even possible ?

What I tried so far is set upped DataDog Lambda Forwarder that sends CloudWatch logs (metrics and alarms I suppose too?) to DD. I gave permission to that lambda. I created some AWS metric filter and AWS alarm to trigger when specific event occurs. I run some lambda code to throw exception and trigger CloudWatch alarm to change its status.

I clearly see lambda logs in DD, but I can't find anything related to my alarms in DD events. And I suppose it's not a problem with DD-AWS integration because we use it in big organization and it was configured long before I joined the company. What am I doing wrong ?

I have a project in which I am building a DNS Forwarder.

I am using a UDP Server socket to listen to the DNS requests on port 53 (client is using the dig command) and I have to forward the received raw DNS request to scapy for dissecting it. I know that scapy is used to forge/send/manipulate packets.

The raw request looks something like this -

I know that the bytecode specification allows classes to have methods with the same signature, differing only in the return type, unlike in the Java language. Some languages even make use of that under certain circumstances. My question is related to reflection:

if in a class I find a (non-private) method with the same name and parameter types as (a non final, non private) one its superclass , and with a return type equal or being a subtype of the return type of the said method in the superclass, when can I assume that code invoking the 'supermethod' statically will always result in the execution of the 'overriding(?)' method (naturally assuming the call is made on an object which is of that class)? Even in cases of other languages compiled to the JVM bytecode, or if runtime code generation is involved, or in hacked synthetic classes like the lambda forwarders?

My question was brought about from noticing how in the Scala standard library, an Iterable[E] has a method:
