Windows will not boot with this method. By renaming the file back to bootmgfw.efi windows will boot again but now linux won't boot. There is no clean solution, other than switch to different computer that doesn't have this issue. Because of issues like this I don't recommend dual booting. Installing only Windows or only Linux is more manageable for not-tech-savvy people.

In windows EFI partition, there will be an EFI/Microsoft/bootmgfw.efi file, I usually rename it to bootmgfw.efi.bak and that allows grub to load.

I have observed that many laptops are hard-coded to boot windows whenever possible. Even with windows bootentry missing, firmware will skip Grub set to first priority and start windows. Only way to make them start Grub is to rename bootmgfw.efi to a different name.

Testcontainers uses 'ryuk' to clean up containers and it needs docker socket mounted within its container to work. So if you had any hardening config that prevents the docker socket access within a container e.g user namespace or SELinux then Testcontainers doesn't work.

And I think it would be nice if Testcontainers 'just worked' with Podman without any additional steps.

Nothing else. Though docker socket issue was important enough.

 

Testcontainers is a library that starts your test dependencies in a container and stop them after you are done using them. Testcontainers needs Docker socket access for mounting within its reaper, so I made a (for now minimal) different library that does not need Docker socket access. It also works with daemonless Podman.

You have to practice switching between neovim and other editors.

You have forgotten how to use a normal editor. I am not making it up, it is a real phenomenon. Similar to when SmarterEveryDay learned to ride a backwards bicycle he forgot how to ride a normal bicycle and essentially had to re-learn it. You have to re-learn how to use a normal editor.

For me the value of podman is how easily it works without root. Just install and run, no need for sudo or adding myself to docker group.

I use it for testing and dev work, not for running any services.

It's the same picture.

Yes it is the ratings on winehq, https://appdb.winehq.org/

And yes, an average user probably going to fire a game, figure out it is not working, and promptly go back to windows, which makes that data less accurate, but what can we do about it?

[โ€“] akash_rawal@lemmy.world 3 points 3 months ago

The left axis is total number of ratings of each type (Garbage, Bronze, Silver, Gold, Platinum) in a given month (not per app). For example for month 2016-07 there were

  "Garbage" => 22
  "Bronze" => 14
  "Silver" => 13
  "Gold" => 55
  "Platinum" => 61

On right side is the average rating. So if I assign values to each rating:

  "Garbage" => 1
  "Bronze" => 2
  "Silver" => 3
  "Gold" => 4
  "Platinum" => 5

I can get an average rating, which will be between 1 to 5.

((22*1) + (14*2) + (13*3) + (55*4) + (61*5)) / (22 + 14 + 13 + 55 + 61)
 ~=  3.721
 

I took each rating for games on Wine Application Database, mapped them to numbers (Garbage -> 1, Bronze -> 2, Silver -> 3, Gold -> 4, Platinum -> 5) and plotted a monthly average.

 

I was exploring direct links between machines, and basically failed to break something.

I assigned IP address 192.168.0.1/24 to eth0 in two ways.

A. Adding 192.168.0.1/24 as usual

# ip addr add 192.168.0.1/24 dev eth0
# ping -c 1 192.168.0.2
PING 192.168.0.2 (192.168.0.2) 56(84) bytes of data.
64 bytes from 192.168.0.2: icmp_seq=1 ttl=64 time=0.051 ms

***
192.168.0.2 ping statistics
***
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.051/0.051/0.051/0.000 ms
#

B: Adding 192.168.0.1/32 and adding a /24 route

# ip addr add 192.168.0.1/32 dev eth0
# # 192.168.0.2 should not be reachable.
# ping -c 1 192.168.0.2
ping: connect: Network is unreachable
# # But after adding a route, it is.
# ip route add 192.168.0.0/24 dev eth0
# ping -c 1 192.168.0.2
PING 192.168.0.2 (192.168.0.2) 56(84) bytes of data.
64 bytes from 192.168.0.2: icmp_seq=1 ttl=64 time=0.053 ms

***
192.168.0.2 ping statistics
***
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.053/0.053/0.053/0.000 ms
#

Does this mean that adding an IP address with prefix is just a shorthand for adding the IP address with /32 prefix and adding a route afterwards? That is, does the prefix length has no meaning and the real work is done by the route entries?

Or is there any functional difference between the two methods?

Here is another case, these two nodes can reach each other via direct connection (no router in between) but don't share a subnet.

Node 1:

# ip addr add 192.168.0.1/24 dev eth0
# ip route add 192.168.1.0/24 dev eth0
# # Finish the config on Node B
# nc 192.168.1.1 8080 <<< "Message from 192.168.0.1"
Response from 192.168.1.1

Node 2:

# ip addr add 192.168.1.1/24 dev eth0
# ip route add 192.168.0.0/24 dev eth0
# # Finish the config on Node A
# nc -l 0.0.0.0 8080 <<< "Response from 192.168.1.1"
Message from 192.168.0.1
 

I am building my personal private cloud. I am considering using second hand dell optiplexes as worker nodes, but they only have 1 NIC and I'd need a contraption like this for my redundant network.

Then this wish came to my mind. Theoretically, such a one box solution could be faster than gigabit too.
