digiKam: store the changes in the database instead of creating a physical file

I'm trying DigiKam and maybe I'm missing something obvious. When I edit a photo, for example, to correct the exposure, digiKam always asks me to save my changes in a file and then create one next to the original (and I do not mean a sidecar / xmp file).

Lightroom Migration I am used to a system where all my changes are stored in the database. If and when I want to have a physical file, I export the photo and Lightroom then I apply all my changes to that new file.

Is there a similar configuration that makes digiKam store all the changes in its database and does not force me to create new jpeg / png?

After the manipulation, how to save the data as an Excel / CSV file?

Hello, I have problems to generate and save data from the manipulation of parameters. Can anybody help me please?

Handle[Plot[{func,x}, {x, 0, 3}]

I want to save the results of x and func.
Thank you very much for your help.

Subsequent processing: Why does not Corel Aftershot 3 open my RAW file?

Apparently (although it's not really apparent) you must first install the profile for your camera.

Here is the answer I received from the help desk:

In aftershot

go to the "Get More" tab (usually shown on the right side with an asterisk)

Camera Profiles> click on "Free" for your camera model> continue with the installation.

Before finally getting that answer, I discovered this way of obtaining this necessary download:

Go to the Corel Discovery Center website to the Aftershot Pro download page and download the AfterShot profile for your camera. If you go to the main page and type "Aftershot download" in the search, you will access the download page that is

It says for AfterShot Pro, but it worked for me for AfterShot 3, the standard version.

On that same page there is a link to your instructions once you have saved the profile. The instructions are the following:

AfterShot Pro 3 Camera Profile Installation instructions:

  1. In AfterShot Pro 3, click "File"> "Install camera …"
  2. Go to your folder of & # 39; Downloads & # 39; (or to the folder in which you saved it)
  3. Select the profile file of the camera
  4. Click on "Open"
  5. Click on "Install"
  6. When you restart, you will have support for the camera you installed.

Why does not this solution appear when looking at the AfterShot support page, I do not know.

wallet – multibit key file

I have a Multibit portfolio file, a key file and a backup, but I can not open them with the password I have.
I can open the key file and make a backup in a plain text editor such as notepad and ++.
I keep reading again and again that, if someone has these plain text files in their hands, my bits disappear.
Can someone tell me how they do it or, better yet, how can I recover my BTC, given the information I have?

How can I write the calculation output in a csv file as the following format?

I arrived at the following list after calculating the hash password of the csv file:

['danial', 5104, 'elham', 9770]

and I will write each name and password in the csv file (update it) in the following order:

danial 5104
elham, 9770

I used the code below, but the output is false.

data =[]
for the item in list 3:
# data =[]
    l3 =[]
    l3.append (item)
#print (l3)
data.append (str (item))
print (data)

with open (& # 39; code.csv & # 39 ;, & # 39; w & # 39 ;, newline = & # 39; & # 39;) as output_file_name:
writer = csv.writer (output_file_name)
writer.writerows (data)
filename_file.close ()

ios – How to make sure that the file is loaded from my application

Short answer: Impossible

Longer response: As soon as you lose control of the hardware (that is, your software runs on a phone that you do not own), you can no longer guarantee that the software that talks to your server is, in fact, the software you wrote.

As you pointed out, there is nothing you can do to prevent the user from entering reverse engineering and find secrets (hashes, private keys, etc.) that you have put there.

All is not lost

All you really need to worry about is that the photo comes from an authenticated user. Since your application (I hope!) Is passing an authentication token generated by the server with each request, you can securely accept any photo that is accompanied by that token.

In other words:

  1. The user logs in to the server through the application.
  2. The server responds with a token that is good for the next XX minutes.
  3. The application includes a copy of the token with each communication to the server

This is oversimplified, and there are tools and libraries to handle this for you.

In other words, how do you make sure that only paying customers use your application to talk to your server? The answer will also answer your question about the acceptance of photos.

The Oracle listener gives "Message 850 not found, there is no message file for product = network, facility = NL"

I just completed the installation of oracle 11g database software on Linux.
Throw netca and configured a listener.
