Modifying private pointer of object within same type (but different object) public method

Asked 2021-Jun-15 at 20:20

I've been attempting to create a node class which mimics a node on a graph. Currently, storage of the predecessor and successor nodes are stored via a node pointer vector: std::vector previous. The vectors for the predecessor/successor nodes are private variables and are accessible via setters/getters.

Currently, I am dealing with updating the pointer values when adding a new node. My current method to update the predecessor/successor nodes is through this method (the method is the same for successor/previous nodes, just name changes):

I have a Graph loaded in pandas and I want to check if my graph has nodes with reciprocity. My dataset looks like this:

The desired output of my code is the reciprocal nodes: (s01, s03)

You can merge the DataFrame with itself after swapping the from and to columns in the right DataFrame. Then sort the merged result and drop duplicates to get the unique pairs of reciprocal nodes.

Can different network be the cause for UnreachableBrowserException exception?

Asked 2021-Jun-15 at 13:57

I have two grid setup's

Local grid setup (hub and nodes are running in my local machine) and my local machine connected to network#1
VM grid setup (hub and nodes are running in my virtual machine) and my virtual machine connected to network#2

When I execute the scripts I need to pass the IP address as a parameter. Here, I can run my scripts successfully in local machine(code is available in local machine) by passing the network#1 IP address but if I pass the network#2 IP address (VM IP address) to local machine then I am getting below exception,

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

As per my knowledge, hub and nodes should be connected to same network. Cannot we run the scripts by passing the VM IP address to local machine?

SLURM and Python multiprocessing pool on a cluster

Asked 2021-Jun-15 at 13:42

I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:

I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:

...

ANSWER

Answered 2021-Jun-15 at 06:17

Pythons multiprocessing package is limited to shared memory parallelization. It spawns new processes that all have access to the main memory of a single machine.

You cannot simply scale out such a software onto multiple nodes. As the different machines do not have a shared memory that they can access.

To run your program on multiple nodes at once, you should have a look into MPI (Message Passing Interface). There is also a python package for that.

Depending on your task, it may also be suitable to run the program 4 times (so one job per node) and have it work on a subset of the data. It is often the simpler approach, but not always possible.

QUESTION

Solving Time-constrained CVRP with two vehicle types in Google or-tools

Asked 2021-Jun-15 at 12:54

I am modeling a Time-constrained CVRP. The problem is to minimize the total travel time (not including the package dropping time) subject to vehicle (delivery) capacity and total time spent (per vehicle) constraints. The package dropping time refers to an additional time to be spent at each node, and the total time spent equals to the travel time plus this additional time. I have the below model that works for a single vehicle-type case. I would like to introduce two-vehicle type concept in there, meaning that I have a set of V1 type vehicles and another set of V2 type vehicles. The only difference of the vehicle-types is the per time cost of travel. Let x denote the per time unit cost of travel by V1, and y denote the per time unit travel cost of V2. How can I design the model so that it incorporates this additional aspect?

...

ANSWER

Answered 2021-Jun-13 at 13:34

Simply register two transits callbacks (i.e. one per vehicle type)

Then use the overload of AddDimension() to pass an array of registered transit callback index.

QUESTION

Why does the animation plot provide a different plot than the static plot

Asked 2021-Jun-15 at 11:52

Good morning,

I am creating an animation by connecting 6 nodes coordinates at 10 different time steps.

I start with a test: I first create a static plot for a time equal to 2 (for example) and I get the exact static plot that I am expecting: all and only the consecutive nodes are connected.

Then I create the animation. Unfortunately, the animated plot connects the nodes in the wrong way. You can see that the animation connects the consecutive nodes, but also the second and the second to last nodes.

Any idea why? Thanks

...

ANSWER

Answered 2021-Jun-15 at 11:52

The issue is that in your static plot, you have actually created a list of Line2D objects (try printing line1 and you will see its not a single instance).

But, in the animation function, you just create a single Line2D instance to set the xdata and ydata for.

We can change to creating a list of Line2D instances, then loop over them and set the appropriate x and y data for each segment like so:

Spread specific number of deployment pods per node

ANSWER

Answered 2021-Jun-13 at 12:51

You can use DeamonSet instead of Deployment. A DaemonSet ensures that all (or some) Nodes run a copy of a Pod. As nodes are added to the cluster, Pods are added to them. As nodes are removed from the cluster, those Pods are garbage collected. Deleting a DaemonSet will clean up the Pods it created.

See documentation for Deamonset

Example 1 ...

ANSWER

Answered 2021-Jun-15 at 10:52

Some issues in your code (as it was first posted):

return skipper(prev,curr) is going to exit the loop, but there might be more nodes to be removed further down the list. skipper only takes care of a sub sequence consisting of the same value, but it will not look beyond that. The list is not necessarily sorted, so the occurrences of the value are not necessarily grouped together.
Be aware that the variable prev in skipper is not the same variable as the other, outer prev. So the assignment prev=curr in skipper is quite useless
Unless the list starts with the searched value, dummy.next will always remain None, which is what the function returns. You should initialise dummy so it links to head as its next node. In your updated code you took care of this, but it is done in an obscure way (in the else part). dummy should just be initialised as the head of the whole list, so it is like any other node.

In your updated code, there some other problems as well:

while prev.next: risks to be an infinite loop, because it continues while prev is not the very last node, but it also doesn't move forward in that list if its value is not equal to the searched value.

I would suggest doing this without the skipper function. Your main loop can just deal with the cases where current.val == val, one by one.

Here is the corrected code:

ANSWER

Answered 2021-Jun-15 at 04:46

For Sample 1, just query for single partition and merge results at the client end. This will be much faster. Datastax driver has token aware policy but it will only work when query refers to single partition.

You can refer this link.

For Sample 2, it is an anti pattern query and you cannot expect the client to do all the work for you. If you want to read complete table then you can use spark. Datastax provides spark-cassandra-connector which can provide somewhat same functionality which you have given. Here you can find description of spark-cassandra-connector.

MimeKit Remove gif images from Emails

Asked 2021-Jun-15 at 01:50

I'm trying to strip gif images from emails in order to save storage space in Outlook and our document management system.

Say for example you've got an email approx 2MB's in size and the gif is 1MB. I'm expecting the result of the file size of the email to be 1MB.

The first part uses MimeKit to remove the gif. The problem I find with this code is that if you are not debugging it doesn't reduce the file size by what I'd expect. I've found this is because the image is still in the html properties of the MimeMessage.

You have 2 questions that I'll answer separately.

Why doesn't the size of the message shrink after I remove the gif attachments?

MIME can contain nested multiparts and in your case, it likely does because HTML mail with images are often within a multipart/related which is often within a multipart/alternative, like this:
