            GCE custom hostname reverse lookup in private DNS zones
            Asked 2022-Feb-01 at 09:38

            I want to create an instance in Google Cloud Engine with a custom (private) hostname. For that reason, when creating the instance from the Console (or from an SDK) I supply the hostname, or example instance0.custom.hostname.

            The instance is created and the search domain is set correctly in /etc/resolv.conf For Ubuntu in particular I have to set the hostname with hostnamectl but it is irrelevant to the question.

            Forward DNS lookups work as normal for instance0.custom.hostname. The problem comes when I do a reverse lookup for the private IP address of the instace. In that case the answer I get is the GCE "long" name instead of my custom hostname.

            How can I make the reverse lookup reply with my custom name instead of the GCE?

            I know in Azure you can use a Private DNS Zone with VM auto-registration to handle the "custom hostnames". I tried using a private zone with Google Cloud DNS (PTR records) but with no luck.

            After some serious digging I found a solution and tested it.

            Reverse DNS works even without a "regular" DNS records for your custom.hostname domain.

            To get reverse dns working lets assume your VM's in network. Their IP's are 24,27,54,55 as in my example.

            I created a private dns zone and named it "my-reverse-dns-zone" - the name is just for information and can be anything.

            "DNS name" field however is very important. Since my network address starts with 10 I want all the instances that are created in that network segment to be subject to reverse dns. So the DNS name has to be 10.in-addr.arpa in this case. If you're using 192.168.... or 172.16.... then adjust everything accordingly.

            If you wanted just 10.128.0 then you can put 0.128.10.in-addr.arpa. Then you select the VPC networks zone has to be visible in and voila:

            Then you add the PTR records that will allow this to work. I'm setting all TTL's to 1 minute to shorten the wait :)

            After accepting wait a minute (literally) and test it:

            Is it safe to store, access and HTMLElement objects directly inside an object, vs. relying on CSS selectors?
            Asked 2022-Jan-22 at 09:00

            I have a vanilla Javascript class that builds a bunch of HTML, essentially a collection of related HTMLElement objects that form the user interface for a component, and appends them to the HTML document. The class implements controller logic, responding to events, mutating some of the HTMLElements etc.

            My gut instinct (coming from more backend development experience) is to store those HTMLElement objects inside my class, whether inside a key/value object or in an array, so my class can just access them directly through native properties whenever it's doing something with them. But everything I look at seems to follow the pattern of relying on document selectors (document.getElementById, getElementsByClassName, etc etc). I understand the general utility of that approach but it feels weird to have a class that creates objects, discards its own references to them, and then just looks them back up again when needed.

            A simplified example would look like this:

            In general, you should always cache DOM elements when they're needed later, were you using OOP or not. DOM is huge, and fetching elements continuously from it is really time-consuming. This stands for the properties of the elements too. Creating a JS variable or a property to an object is cheap, and accessing it later is lightning-fast compared to DOM queries.

            Many of the properties of the elements are deep in the prototype chain, they're often getters, which might execute a lot of hidden DOM traversing, and reading specific DOM values forces layout recalculation in the middle of JS execution. All this makes DOM usage slow. Instead, create a simplified JavaScript model of the page, and store all the needed elements and values to the model whenever possible.

            A big part of OOP is just keeping up states, that's the key of the model too. In the model you keep up the state of the view, and access the DOM only when you need to change the view. Such a model will prevent a lot of "layout trashing", and it allows you to bind data to elements without actually revealing it in the global namespace (ex. Map object is a great tool for this). Nothing beats good encapsulation when you've security concerns, it's an effective way ex. to prevent self-XSS. Additionally, a good model is reusable, you can use it where ever the functionality is needed, the end-user just parametrizes the model when taken into use. That way the model is almost independent from the used markup too, and can also be developed independently (see also Separation of concerns).

            A caveat of storing DOM elements into object properties (or into JS variables in general) is, that it's an easy way to create memory leaks. Such model objects are usually having long life-time, and if elements are removed from the DOM, the references from the object have to be deleted as well in order to get the removed elements being garbage-collected.

            In practice this means, that you've to provide methods for removing elements, and only those methods should be used to delete elements. Additionally to the element removal, the methods should update the model object, and remove all the unused element references from the object.

            It's notable, that when having methods handling existing elements, and specifically when creating new elements, it's easy to create variables which are stored in closures. When such a stored variable contains references to elements, they can't be removed from the memory even with the aforementioned removing methods. The only way is to avoid creating these closures from the beginning, which might be a bit easier with OOP compared to other paradigms (by avoiding variables and creating the elements directly to the properties of the objects).

            As a sidenote, document.getElementsBy* methods are the worst possible way to get references to DOM elements. The idea of the live collection of the elements sounds nice, but the way how those are implemented, ruins the good idea.

            The vectors setting is not related to the transformer or what you're trying to do.

            In the new config, you want to use the source option to load the components from the existing pipeline. You would modify the [component] blocks to contain only the source setting and no other settings:

            How to add a value based on another field's value
            Asked 2022-Jan-18 at 08:43

            I'm new to Data Factory. I'm trying to copy the data from a source to Dataverse. So far I have a basic demo that allows me to read data from the source, perform a simple lookup, set the guid and add a static value by using "additional columns" in the source options and copy all of that to my Dataverse table.

            However I have a couple of fields in my source data that don't match what I need for Dataverse. E.g. I have a column with 1 or 0 as a value that requires true/false in Dataverse. So I need to something like an "if else" where for every row I can check the value of a field and create a new value based on that that I can later use for lookups and/or copying the data to Dataverse.

            I've been looking at the Docs but its a bit unclear to me how I should go about this. How can I best check the value of a field and create a new field with the value I need based on the existing value?

            Data flows in Azure Data Factory is the thing for you.

            You can use transformations like Derived column transformation in mapping data flow to generate new columns or modify existing fields. Here you can update columns by identifying their data using patterns, conditions and expressions to set new values.


            Using expression as below to identify a column with 1 or 0 and set required value true/false.

            Sense behind the LDAP lookup feature in log4j
            Asked 2021-Dec-20 at 07:48

            Recently a 0-day exploit got disclosed, that uses a security vulnerability in log4j which allows unauthorised remote code execution.

            I'm wondering, what was the actual reason, why log4j has implemented this JNDI lookups, which have cause the vulnerability at all?

            What would be an example for using this LDAP lookup feature in log4j?



            Answered 2021-Dec-20 at 07:48

            Log4j is a popular logging framework used in Java (you can figure the popularity by seeing the widespread impact of the vulnerability). Log4j offers a specific feature, where you can add tokens to your logging string, that get interpolated to fetch specific data. E.g. "%d{dd MMM yyyy}" will insert the date at which the message was logged.

            In the mean time JNDI (Java Naming and Directory Interface) is commonly used for sharing configuration settings to multiple (mirco)services.

            You can imagine a situation where somebody would like to log configuration settings in e.g. error situations.

            See this article explaining a bit

            A Java based application can use JNDI + LDAP together to find a Business object containing data that it might need. For example, the following URL ldap://localhost:3xx/o=BusinessObjectID to find and invoke theBusinessObject remotely from an LDAP server running on either a same machine (localhost) on port 3xx or remote machine hosted in a controlled environment and goes on to read attributes from it.

            The update it refers to mentions it as "LOG4J2-313: Add JNDILookup plugin." The motivation is found in the Apache JIRA entry

            Currently, Lookup plugins [1] don't support JNDI resources. It would be really convenient to support JNDI resource lookup in the configuration.

            One use case with JNDI lookup plugin is as follows: I'd like to use RoutingAppender [2] to put all the logs from the same web application context in a log file (a log file per web application context). And, I want to use JNDI resources look up to determine the target route (similarly to JNDI context selector of logback [3]).

            Determining the target route by JNDI lookup can be advantageous because we don't have to add any code to set properties for the thread context and JNDI lookup should always work even in a separate thread without copying thread context variables.

            [1] http://logging.apache.org/log4j/2.x/manual/lookups.html [2] http://logging.apache.org/log4j/2.x/manual/appenders.html#RoutingAppender [3] http://logback.qos.ch/manual/contextSelector.html

            The big problem with log4j, is that by default all string interpolation of all modules is turned on. In the mean time it has become opt-out, but it wasn't always.
