I'm trying out Martini, which adds some nice functionality upon Go's basic net/http package.
I was wondering tho. How can I, like Django does too, let the server restart itself on source-file changes? I know how to monitor a file, but I'm not sure how to retrigger the Server within the same process.
I'm guessing to trigger http.ListenAndServe again, but I have a feeling it doesn't go well with instance already running.
Do I need to spawn a subprocess/daemon to get this working?
Maybe you need gin ?

You may give it a try
Fresh is a command line tool that builds and (re)starts your web application everytime you save a Go or template file.
You'll need to use an external tool that can watch a directory/files and run a command. I'd recommend reflex which is written in Go itself:
(modifying the example in the README):
# Rerun make whenever a .go file changes
reflex -r '\.go$' ./mymartiniapp

So im building app based on Express and using Prisma ORM. What i need is to SSH to a server, open up express.js console and create new db entry using prisma. Something similar to python manage.py shell for Django or rails console for Rails. Is there a solution for this of any kind?
Like I pointed in the comment there is a way ( kind of ) to get access to a running express instance. If that's all you need follow:
How can I open a console to interact with Express app?
Express doesn't exactly have a feature like rails console which is a framework feature in that case.
That said, I question the long term implication of this approach. If you really just need to seed some data, write an "init" script, and call it after you ssh into a server or using some CI/CD approach. This is more re-usable, since you can even pass a json file to the script to load dynamic data.
Also, Prismajs has an official way to seed the data ( if that's what you need) that you can leverage:
https://www.prisma.io/docs/guides/database/seed-database
UPDATE:
If you are able to run to code on your machine and point the remote database, then you can use node --inspect to debug in a chrome console. Which should give you about the same effect as a rails REPL

How could I make a script that runs when the metasploit handler receives a new session?
By the way, the script should check if a file exists, and if it doesn't, it should upload a file to the victim.
I'm pretty sure I know how to write the script, I just don't know how to make it run when the listener (handler) receives a session
I found out how to do it. Use the AutoRunScript (advanced) option and it will work.
Say I want to run a custom Node script on my DocPad server once a day (like a cron job), where would I put it? I can build a Node script that does stuff after an interval, I'm more curious about where to reference / run the script in the DocPad server.
A plugin is possible, though I've seen that you can require Node libraries within the DocPad configuration file so it could go in there.
Is there a suggested way to approach this?
If you're wanting something purely cron-like, probably using the docpadReady event would be the way to go, doing something like:
docpadReady: ->
require('schedule').every('2 minutes').do ->
require('safeps').spawn('your cron job')
Alternatively, maybe DocPad's regenerateEvery configuration option is suitable. This tells DocPad to regenerate every X millseconds, which will naturally call the generate events that you could hook into.
Alternatively, is there a need for these crons to run on the same server as DocPad? If not, you could do them completely separately.
A final option, is to see if your server you are deploying to supports spawning multiple files. So DocPad's Server is spawned, and so is cron, with DocPad not knowing about the cron task at all.
So I've been meaning to create a cron job on my prototype Flask app running on Heroku. Searching the web I found that the best way is by using Flask-Script but I fail to see the point of using it. Do I get easier access to my app logic and storage info? And if I do use Flask-Script, how do I organize it around my app? I'm using it right now to start my server without really knowing the benefits. My folder structure is like this:
/app
/manage.py
/flask_prototype
all my Flask code
Should I put the 'script.py' to be run by the Heroku Scheduler on app folder, the same level as manage.py? If so, do I get access to the models defined within flask_prototype?
Thank you for any info
Flask-Script just provides a framework under which you can create your script(s). It does not give you any better access to the application than what you can obtain when you write a standalone script. But it handles a few mundane tasks for you, like command line arguments and help output. It also folds all of your scripts into a single, consistent command line master script (this is manage.py, in case it isn't clear).
As far as where to put the script, it does not really matter. As long as manage.py can import it and register it with Flask-Script, and that your script can import what it needs from the application you should be fine.
Is there way to invoke a CakePHP console shell on server without shell access? I have written a shell for performing some once off (and hence not a cron task) post DB upgrade tasks.
I could always just copy the logic into a temporary controller, call its actions via http and then delete it, but was wondering if there was a better way to go about it.
It seems that this is a one off script you might want to typically be running after DB updates right?
If that's the case, you can make it part of your "DB update script"
If you use anything like capistrano, you can include there too.
In all cases, if you don't want to touch the shell, I agree that having a controller to call the console code (or any php file running exec() as mentioned previously) would do the trick.
Also, if you want to run it just once and have it scheduled - don't forget that you have the "at" command (instead of cron) which will run it at that scheduled date (see http://linux.about.com/library/cmd/blcmdl1_at.htm)
Hope it helps,
Cheers,
p.s: if its a console shell and you don't want to run it from the console, then just don't make it a console shell.
I have to agree with elvy. Since this is something that you need to do once in a while after other events have happened, why not just create an 'admin' area for your application and stick code for that update in there?
you may be able to use php's exec function to call it from any old php script.
