How can I get LOAD DATA LOCAL INFILE to work for MySQL 8.0.21 on a Windows machine?

I’ve created a file: 'C:\fff.txt' which contains data for my database table. Then I’m trying to load data from that file like this:

LOAD DATA LOCAL INFILE 'C:\fff.txt' INTO TABLE fff LINES TERMINATED BY '\r\n';  

but I get the following error all the time:

ERROR 2 <HY000>: File 'C:\fff.txt' not found (OS errno 2 - No such file or directory) 

I’ve added local_infile=1 to [mysql] and [mysqld] sections of my.ini file. When I type: SHOW GLOBAL VARIABLES LIKE 'local_infile'; I can see that it’s set to 'ON'. Is there a way to solve this problem?

Make a density plot from a file where the data makes a shape with a hole in it

I have a .dat file and I want to make preferably a density (or surface) plot with it.

ListDensityPlot[f, ColorFunction -> "Rainbow", Axes -> False,   Background -> Black,   PlotLegends ->    Placed[BarLegend[Automatic, LegendMargins -> {{0, 0}, {10, 6}},      LegendMarkerSize -> {15, 300}, LegendLabel -> "F"], After] ,   AspectRatio -> 0.5,  PlotRange -> All] 

The data has the shape of a not perfectly round donut seen from above, so there’s a hole inside and the density and surface plot commands apply the color of the ColorFunction as if it’s 0 to the part in the center that corresponds to the hole. Is there a way that the part in the middle doesn’t get colored? Or can I assign specifically black to the values that are "0" (but where in reality there’s not data) and still use the Color Function?

Best way to save game data in Unity

I am currently developing a game in unity and I want to add some sort of saving system that saves the following:

  • Locked / unlocked level.
  • The amount of money the player has.
  • Items / perks that the player has.

As you can see, the data I want to save is global, and has nothing to do with any specific scene.

How would you reccomend save this kind of data? I have heard about the EasySave asset but I don’t know if it is the right choice: it is pretty expensive and I belive that there has to be some easier, cheaper (even free) way to save the data.

I’ll appreciate any answer or consideration.

As a contractor how do I work on multiple client networks without data leakage?

I am a contractor who does development for more than one client. Let’s call them Client A, Client B, and Client X.
I use my own laptop for all 3 clients.
Throughout the day, I have to work on and respond to emails and instant messages about projects for all 3 clients.
In order to work on Client X’s project, I must be connected to their VPN.
Client X performs SSL deep inspection on the traffic on their network. (I get errors from sites/apps that enforce key pinning)

I’m worried that information about Client A and Client B, (not to mention my own sensitive information) might be exposed to Client X. How can I prevent this, but still maintain my ability to communicate with A and B while working on X’s network?

I’ve tried giving each client its own VM on my machine, but the hefty resource requirements of the software I have to use (IDE) makes this prohibitively slow, to say nothing of the licensing difficulties.

Collecting consumer contact information to alert individuals in case of data breach for B2B companies

If you are a B2B company [US], you may collect data on your clients as well as your clients’ customers. For example, let’s say the only thing you need to collect is your clients’ customers’ names.

In the case that your company has a data leak and the individuals’ names are shared with an unauthorized third party, (I believe) you have an obligation to inform someone.

What is the standard practice? Do you directly email the individual and say their information was leaked? Or do you give your client (a business) a list of the client’s whose data was impacted and let them reach out to the impacted clients.

In the case of emailing the impacted clients directly, what if you do not collect their contact information, and have no way to contact them?


Real world example: my personal data was leaked by a B2B software company that I had never heard of. I was contacted by the software company directly as well as their client who I had used the services of. Was it the responsibility of the B2B software company to collect my email in case they needed to contact me directly?

Keeping data confidential from the system administrator


Problem

How do I ensure that I cannot access confidential data manually through the database? Practically speaking, this is a firestore database on google cloud, and I have access to the administrator google account. For the purposes of this question, we assume the code is perfect, and is trusted to be not malicious in any way.

I’m developing software for a client, and one of the requirements is that the data is only accessible by two other people, and I am not one of them. It’s a small project, and I’m both the sole developer and system administrator. I’m capable of ensuring data confidentiality when the only point of access is the application, but due to the system administrator role I also have direct access to the database.

Possible Solutions

  1. Remove my admin access to the database.

    While it would solve the problem, it would also make further development and support rather difficult.

  2. Use encryption

    Possible, if I only encrypted the records that were confidential. It would slightly impact support but not to any major extent. The main problem here is how to ensure I don’t have access to the decryption key, while the server does.

  3. Use database permissions

    As far as I can tell, google firestore only has permissions for different actions, where I would need to have row or column based permission. I could probably do it with table based permission too. Technically speaking as administrator I could add permission back, but so long as it kept a history of permission changes this should be fine.
