Which encryption cypher is used when using zip -e?

I am looking for a cross-platform way to encrypt credentials I need to send to a client.

I know encrypted zip archives leak metadata and can be tampered with, but how strong is the encryption cypher?

zip -ejr "/path/to/folder.zip" "/path/to/folder"

javascript – Are spritesheets worth it? Is a zip a good alternative?

First of all, there are already image formats with compression. In particular the PNG format supports lossless compression. Furthermore, while it is true that taking a bunch of PNGs and zipping them might be a gain in size, making a texture atlas (spritesheet or similar) will also reduce the size in similar fashion, in particular if you rank up the PNG compression level when exporting the image.

Thus, a properly exported texture atlas will give you the benefits you list on compression.

Does this mean that you should make everything into a single spritesheet? No. You should put together things that should be loaded together.

It might also be worth noting that spritesheets work better when your images are small and of regular sizes. It might be you are working in a scenario for which spritesheets are not well suited.

Is that the case? I don’t know. Do experiment. If you are not willing to try both techniques to decide, the engineering approach suggest to go with the proven method, and that would be a texture atlas.

You might also be interested in packing algorithms that may minimize the holes in the texture atlas.

beginner – App to seed DB, generate CSVs, and export individually or in complex zip files Rails 5

I have an app whose sole purpose is to seed data files and add the data to different CSVs which are zipped and exported by the user. My application controller is filled with lines that all look like this:

  def export_tips
    @appointments = Appointment.order('service_id')
    send_data @appointments.to_csv_tips, filename: 'tips.csv'
  end

  def export_ticketpayments
    @appointments = Appointment.order('service_id')
    send_data @appointments.to_csv_ticketpayments, filename: 'ticketspaymentitems.csv'
  end

  def export_batchmanifest
    @batchmanifests = Batchmanifest.all
    send_data @batchmanifests.to_csv_batchmanifest, filename: "batch_manifest-#{Date.today}.csv"
  end

  def export_pets
    @clients = Client.all
    send_data @clients.to_csv_pets, filename: 'pets.csv'
  end

  def export_clients
    @clients = Client.all
    send_data @clients.to_csv_clients, filename: 'clients.csv'
  end

I have it in the application controller because I used it in multiple different areas including creating single CSV exports and creating complex zip files with multiple zips and CSVs inside.

Some things that I have tried to cleanup the code include:

  • Different variables of this:
    def csv_export (model, filename)
    @model.pluralize = (model.titleize).all
    send_data @model.pluralize.filename, filename: filename
    end
  • Having each one in its own controller (could not access them from different views and other controllers easily)
  • I also tried to figure out how to create my own module, but was unable to do so.

My application record is just as bad with repeated lines simply meant to export the CSVs:

      def self.to_csv_appointments
        attributes = %w(appointment_id location_id employee_id client_id child_id notes 
        has_specific_employee start_time end_time)
        CSV.generate(headers: true) do |csv|
          csv << attributes
          all.each do |appointment|
            csv << attributes.map { |attr| appointment.send(attr) }
          end
        end
      end
    
      def self.to_csv_appointmentservices
        attributes = %w(appointment_id service_id price duration)
        CSV.generate(headers: true) do |csv|
          csv << attributes
          all.each do |appointment|
            csv << attributes.map { |attr| appointment.send(attr) }
          end
        end
      end

      def self.to_csv_tickets
        attributes = %w(ticket_id location_id client_id ticket_status employee_id 
        employee_id start_time)
        headers = %w(ticket_id location_id client_id status employee_id 
        closed_by_employee_id closed_at)
         CSV.generate(headers: true) do |csv|
         csv << headers
          all.each do |appointment|
           csv << attributes.map { |attr| appointment.send(attr) }
          end
        end
      end

For the application record, I have tried similar methods as those listed for the application controller, but to no avail. Again, I use the code in application record instead of in the individual model files because I need to access these in multiple parts of the site.

The code from the application controller is used mostly in the static controller and buttons on the view files. I need the ability to create the file sets, as listed below, but also allow the user to export just one CSV.

Examples from static controller to built the zip files:

def create_appointments_zip
  file_stream = Zip::OutputStream.write_buffer do |zip|
    @appointments = Appointment.order('service_id')
    zip.put_next_entry "appointment_manifest.csv"; zip << File.binread("#{Rails.root}/app/assets/csvs/appointment_manifest.csv")
    zip.put_next_entry "appointments.csv"; zip << @appointments.to_csv_appointments
    zip.put_next_entry "appointment_services.csv"; zip << @appointments.to_csv_appointmentservices
    zip.put_next_entry "appointment_statuses.csv"; zip << @appointments.to_csv_appointmentstatuses
  end
  file_stream.rewind
  File.open("#{Rails.root}/app/assets/csvs/appointments.zip", 'wb') do |file|
    file.write(file_stream.read)
  end
end

 def export_salonset
    create_appointments_zip
    create_tickets_zip
    create_inventory_zip
    create_memberships_zip
    file_stream = Zip::OutputStream.write_buffer do |zip|
      @saloncategories = Saloncategory.all
      @salonservices = Salonservice.all
      @clients = Client.all
      @locations = Location.all
      @salonpricings = Salonpricing.all
      @staffs = Staff.order("location_id")
      zip.put_next_entry "batch_manifest.csv"; zip << File.binread("#{Rails.root}/app/assets/csvs/batch_manifest_simple_salon.csv")
      zip.put_next_entry "categories.csv"; zip << @saloncategories.to_csv_saloncategories
      zip.put_next_entry "clients.csv"; zip << @clients.to_csv_clients
      zip.put_next_entry "employees.csv"; zip << @staffs.to_csv_staff
      zip.put_next_entry "locations.csv"; zip << @locations.to_csv_locations
      zip.put_next_entry "pricings.csv"; zip << @salonpricings.to_csv_pricings
      zip.put_next_entry "services.csv"; zip << @salonservices.to_csv_salonservices
      zip.put_next_entry "appointments.zip"; zip << File.binread("#{Rails.root}/app/assets/csvs/appointments.zip")
      zip.put_next_entry "inventories.zip"; zip << File.binread("#{Rails.root}/app/assets/csvs/inventories.zip")
      zip.put_next_entry "tickets.zip"; zip << File.binread("#{Rails.root}/app/assets/csvs/tickets.zip")
      zip.put_next_entry "addonmappings.csv"; zip << File.binread("#{Rails.root}/app/assets/csvs/addonmappings.csv")
    end
    file_stream.rewind
    respond_to do |format|
      format.zip do
        send_data file_stream.read, filename: "salon_set.zip"
      end
    end
    file_stream.rewind
    File.open("#{Rails.root}/app/assets/csvs/salon_set.zip", 'wb') do |file|
      file.write(file_stream.read)
    end
  end

I know there must be a better way than writing these same lines over and over. The code works, my site works (amazingly), but I would be embarrassed for any seasoned developer to see the repository without laughing. Any help is appreciated!

About zip files and adding a file to zip

I added a file to the existing zip file that has a zip signature.

Does the zip signature remain same or does it change after adding a file to the zip?

Will I have a problem developing my module using a zip installation?

I’m trying to create and learn how to develop a module for Magento 2. The problem is that installation through the composer is too dependent on handling, is necessary to install and enable, and uses too much for each installation of the operating system. I chose to do the installation via zip file, while the resolved one removes the installation via composer. My question is whether my module can stop working when I use a compositor installation.
