QUESTION
i am trying to make login function but the function always make my input was wrong even i using the correct data from database
here's my login section
...ANSWER
Answered 2021-Jun-15 at 11:46From your image, it shows that the password (firsttt) is in the database in plaintext. However, when you are querying it, you are using md5 to hash it before you check the database. The MD5 hash of firsttt is 568745cb18115e238907fbf360beb37a and since that doesn't match the field in the database it does not return a result. If you want to see the result return positive, you can remove the md5() function for now just to see it but you should secure the database in some other way.
MD5 alone would not be secure as common passwords are easily detected. The passwords need to be hashed and salted, which makes them more unique and unindentifiable.
For example, php provides a password_hash function that will hash and salt the password: https://www.php.net/manual/en/function.password-hash.php
which you should use when adding a user to the database.
They also provide a password_verify function that will be able to tell you if the submitted password is correct: https://www.php.net/manual/en/function.password-verify.php

QUESTION
If I need to freeze the output layer of this model which is doing the classification as I don't need it.
...ANSWER
Answered 2021-Jun-11 at 15:33You are confusing a few things here (I think)
Freezing layersYou freeze the layer if you don't want them to be trained (and don't want them to be part of the graph also).
Usually we freeze part of the network creating features, in your case it would be everything up to self.head.
After that, we usually only train bottleneck (self.head in this case) to fine-tune it for the task at hand.
In case of your model it would be:

QUESTION
For a project, I'm trying to plot on the same figure (using subplots) to "graph". The data have been collected using a database (but for my problem here, I tried to selected only reasonable number of value).
On the left of the figure, I plot the temperature in JFK during 10 consecutive days whereas on the right, I plot a scatter of the temperature in various locations in the US on a specific day.
This is the part where it gets tricky : I'd like to use a colormap to display the variation of the temperature across the country and even if I've been able to change the color of the colormap, the dots of the scatter are all with the same color
Here are my variables:
...ANSWER
Answered 2021-Jun-11 at 06:21Thanks to @JohanC, I've been able to fix my issues:
Using scatter1=ax[1].scatter(longitude,latitude,cmap='RdBu',s=20) and fig.colorbar(scatter1, ax=ax[1], pad=0) have help ensuring the colorbar was not overflowing below the graph. This is what I get when I'm inserting these line in my code :
Then, by working on the code by my self, I realized that in order to have the dots in different colors depending on the temperature, I could 'simply' remove the line cmap = plt.cm.RdBu and, change in the scatter function (scatter1=) the value to temp: scatter1=ax[1].scatter(longitude,latitude,c=temp,s=20)
QUESTION
This sounds like an easy task, but I already spent hours on it. There're several posts with a similar headline, so let me describe my problem first.
I have H264 encoded video files, those files show records of a colonoscopy/gastroscopy.
During the examination, the exterminator can make some kind of screenshot. You can see this in the video because for round about one second the image is not moving, so a couple of frames show the "same". I'd like to know when those screenshots are made.
So in the first place I extracted the image of the video:

QUESTION
I am wondering if it is possible to pull a single columns values from a csv file using javascript?
Right now I have a designed Web page that will log the speed a status of some fans. All the data I am getting for the speed and status will be logged in a csv file. I am currently stuck on figuring out how to link and pull specific values from the csv. Here is the code I have a section of my page https://jsfiddle.net/IzzyStrauch/mtorf3eL/4/
I am trying to get it so that the csv values will change the numbers and lights.
I am planing on the csv looking something like this
...ANSWER
Answered 2021-Jun-09 at 19:49I simplified your HTML and CSS to make the program flow a bit better.
First, you will need to parse your CSV. The most common conversion it to JSON. After you have your JSON, destructure or access the first item. After you have the first item, loop over the keys and determine if you need to set the value or the status. Once you have figured that out, query for and update the appropriate elements.
