QUESTION
I am reading the book Lisp written by Winston. In addition, I am using SBCL, Emacs, and Slime.
In chapter 8 (about macros), the book has the following exercise:
Problem 8-7: A stack is a learnly ordered set of things that can be accessed using push and pop operations. OUR-PUSH adds a new item to the top of the stack, while OUR-POP removes the item on top of the stack. A list can be used to represent a stack, with the first element corresponding to the item on top. Define OUR-PUSH and OUR-POP as macros. OUR-PUSH takes two arguments, the item to be pushed and the name of a variable whose value it the list representing the stack. The value returned is the enlarged list. OUR-POP takes a single element, the name of the variable whose value is in the list. The value returned is the item popped. In both cases the value of the variable is changed to reflect the new state of the stack.
I got it correct for the pop function. However, I had a trouble with the push re-implementation. This is the answer-sheet:

I want to add socket.io on the index and it is like this i need to figure out how to do this with this code here and i want to emit the data when a route is called in another file how can i do this? you can see i tried down the code to put the socket io but i don't know can someone help please? also this is made in the backend like this is supposed to be an API and i'll not have a front-end and that's my problem i never used socket.io like this
...ANSWER
Answered 2022-Jan-26 at 18:48You can have the socket join a room on connection and attach io to the app object with app.set('io', io). This can then be accessed in controllers with req.app.get('io'), and you can emit to specific rooms.

QUESTION
I'm using winston js for my node js app logging. I'm deploying my dockerized app on GKE and want to store my files outside the container. Where should I store those files and what path should be mounted.
I'm really new to the kubernetes volumes and can't find the right tutorial to follow.
...ANSWER
Answered 2022-Jan-15 at 22:08There are multiple options to do or follow, now first thing why you want store logs in files ?
You can just push the logs to the stack driver service of GCP and your logs will be stored over there, in that case, no need to use any volume or extra configuration required.
Stack driver logging is managed service you can search the logs and push the logs from all the containers. In this way, your service will be stateless and you don't need to configure the volume for your deployment. Since container or POD is stateless running inside the cluster you can easily scale the application also.
Still, if you are planning to use the volume there are plenty of option with below description:
Use Node volume :
In this container will create the logs files inside Node's volume on which it's running.
Example : https://kubernetes.io/docs/concepts/storage/volumes/#hostpath
Cons :
- Logs will get removed as soon as Node is auto-scaled or removed from GKE cluster during maintenance or so.
- Container can schedule to any node any time, or seq of logs might create the issue.
Use PVC disk :
If you will use the Disk to store your logs for long persistent time like 30-40 days it will work.
You create volume which will be used by POD in K8s and POD can use this volume to create file and store and it won't get deleted from that disk unless you do it.
Example : https://cloud.google.com/kubernetes-engine/docs/concepts/persistent-volumes
Cons :
- Only a single POD (Replica) can connect with this if you are using the access mode ReadWriteOnce, this can create issue if you are planning to do autoscaling or want to many replicas.
NFS & EFS
You have to use the ReadWriteMany access Mode if you are planning to store all replicas or PODs logs in K8s.
For ReadWriteMany option you can use any NFS service or GCP EFS service.
in this case all your PODs will write to the Single Volume NFS or EFS system and logs will be saved there, but the extra configuration is required.
Extra :
The best option is to push logs to stack driver without during many configurations of logs and you can manage retention period over there. Just start pushing logs from the application container and you can scale replica seamlessly.

QUESTION
I'm making a blog type website, and it's pretty much done but earlier today I realized a major flaw in it. When creating creating a username (when registering or editing one's profile) it asks for certain characters, but it won't allow me to have spaces in my name.
For example if I wanted my username to be "Winston Pichardo", it won't be possible because that will trigger the error that says "only letters and digits as @/./+/-/_ are allowed".
So how can I edit these 'requirements' to allow spaces in the username?
I'm using the default django forms and combining those with Crispy Forms to make it all work.
these are some examples of my code:
