I am using .gitignore for a C# solution and I'd like to ignore a file that's generated on build, to stop it getting checked in. The only consistent parts of the file name are the start and the end. Example:

Cloud.Core[.example1.example2.example3].xml

It always begins with "Cloud.Core" and ends with ".xml". It could have various connotations in between, such as:

• Cloud.Core.xml
• Cloud.Core.Example1.xml
• Cloud.Core.Example2.Example2.xml

What mask should I add to my gitignore to bypass a file which has a start/end as described?

I've tried these and a few other variations with luck:

• Cloud.Core*.xml
• Cloud.Core[a-z[.]].xml

I know gitignore uses globbing but I can't seem to work out the correct combination I need: http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm

Thanks for any pointers in advance.

In a project of mine I am working towards secure TCP communications between a client and a server across an insecure network. Initially I was thinking about just passing this off to openssl, but I've concluded that (because of reasons beyond the scope of this question), I would prefer to deal with the DSA keys manually. While that part is simple enough, there is one remaining problem: How would I send the public key the server while making sure there's no MITM intercepting this key and replacing it with its own?

I have been looking into Diffie-Hellman key exchange algorithm, but I haven't found a way of implementing this in my code without reinventing the wheel, and I am struggling with finding an existing library for it, so I have decided to step back a bit and simply ask:

Is there a library or some other method that allows me to exchange keys securely, while allowing me to apply the keys manually? Basically, I want to do the actual encryption/decryption with keys myself, but I need a reliable way of exchanging the public keys involved.

Using python 3.6.9 on linux. I have access to openssl and the usual linux-tools.

On Ubuntu 14.04, I use Pycharm Professional Edition. When I start a debug session, I see the following message in the event log of Pycharm:

Python Debugger Extension Available

Cython extension speeds up Python debugging

Install How does it work

Clicking on Install leads to a popup window with an error message:

I depict here the text, too, so that it can be found by others more easily:

Compile Cython Extensions Error

Non-zero exit code (1):

unable to execute 'gcc': No such file or directory

error: command 'gcc' failed with exit status 1

To look for a solution:

1. I compiled Cython speedups manually according to the link mentioned above: /usr/bin/python3 //helpers/pydev/setup_cython.py build_ext --inplace. This finishes successfully, but does not help with the error message.

2. I added the python-3.6-dev repository: sudo add-apt-repository ppa:deadsnakes/ppa, executed: sudo apt-get update && sudo apt-get dist-upgrade and installed python-3.6-dev: sudo apt-get install python3.6-dev

   It finishes successfully, but does not change the above popup error message.

What else can I check or execute?

EDIT regarding the installation of gcc, it looks like the following:

When I wanted to run perf under WSL, I met the follow question:

WARNING: perf not found for kernel 4.4.0-18362

You may need to install the following packages for this specific kernel:

linux-tools-4.4.0-18362-Microsoft

linux-cloud-tools-4.4.0-18362-Microsoft

You may also want to install one of the following packages to keep up to date:

linux-tools-Microsoft

linux-cloud-tools-Microsoft

But I can't find packages called linux-tools-4.4.0-18362-Microsoft or linux-cloud-tools-4.4.0-18362-Microsoft. I guess the package names are generated automatically.

I also tried to use perf in docker container. However, docker container use the same kernel as the hosts.

Is there any method to run perf under WSL?

I heard that perf can be used in WSL2. But after I upgraded to WSL2, it shows the similar error message:

WARNING: perf not found for kernel 4.19.84-microsoft

You may need to install the following packages for this specific kernel:

1. I have a hardware dev kit on my desk attached to my Windows laptop via USB. The dev kit allows you to flash a chip via USB. I would like to expose this device to my server environment using usbip.

2. On my Windows PC I run a virtualbox with USBIP server. I have bound the hw dev kit. The server is listening on port 3240 which is forwarded by Virtual Box to the host (laptop) port 7023

3. Using SSH I login into my server. I have setup an SSH remote tunnel so that port 3240 on the server will sent requests to port 7023 on the laptop.

Summary

USBIP server port 3240 --Virtual Box--> laptop port 7023 <--SSH -R :3240:localhost:7023

On the server this is working:

At the page https://developer.android.com/studio/index.html, there is a link to the Android SDK tools for Linux, which I'd like to download by a script. Unfortunately, there is no "easy" link to use to download the latest version, so I'd like to extract the link from the HTML itself.

The link is identified by the id linux-tools and is contained on multiple lines:

I knew that "perf" tool requires installation correspond to specific linux kernel versions. And I knew that all docker images run with the same linux kernel version, no matter linux distribution version.

I'm using ubuntu 16.04 inside docker and already installed linux-tools-common, start perf tell me I still lack some packages:'

We have a Microsoft Sql 2014 database on a remote windows server. I am trying to develop a QT GUI app which connects to this database. The app is in Linux/c++ environment. I tried using QtSql APIs to connect to that database.
