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.
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.
It wants you to put dummy details as fast as you can.
It is a game, but it might also be a card grabber.
I did not make this, and you’re supposed to put dummy details there. Don’t put actual credit card information.
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.
No… too hard.
npm ruin dev running shittier could be a nice prank… depending on how often it gets typed.
I didn’t know the answer either, but usually you can compose solution from solutions of smaller problems.
solution(0): There are no disks. Nothing to do. solution(n): Let’s see if I can use solution(n-1) here. I’ll use solution(n-1) to move all but last disk A->B, just need to rename the pins. Then move the largest disk A->C. Then use solution(n-1) to move disks B->C by renaming the pins. There we go, we have a stack based solution running in exponential time.
It’s one of the easiest problem in algorithm design, but running the solution by hand would give you a PTSD.
Replacing “Programmers:” with “Program:” is more accurate.
Tower of Hanoi is actually easy to write program for. Executing it on the other hand…
Technically, containers always run in Linux. (Even on windows/OS X; on those platforms docker runs a lightweight Linux VM that then runs your containers.)
And I wasn’t even using Docker.
How I lost a Postgres database:
Just did some basic testing on broadcast addresses using socat, broadcast is not working at all with /32 addresses. With /24 addresses, broadcast only reaches nodes that share a subnet. Nodes that don’t share the subnet aren’t reachable by broadcast even when they’re reachable via unicast.
Edit1: Did more testing, it seems like broadcast traffic ignores routing tables.
On 192.168.0.2, I am running socat -u udp-recv:8000,reuseaddr - to print UDP messages.
Case 1: add 192.168.0.1/24
# ip addr add 192.168.0.1/24 dev eth0
# # Testing unicast
# socat - udp-sendto:192.168.0.2:8000 <<< "Message"
# # Worked
# socat - udp-sendto:192.168.0.255:8000,broadcast <<< "Message"
# # Worked
Case 2: Same as above but delete 192.168.0.0/24 route
# ip addr add 192.168.0.1/24 dev eth0
# ip route del 192.168.0.0/24 dev eth0
# # Testing unicast
# socat - udp-sendto:192.168.0.2:8000 <<< "Message"
2024/02/13 22:00:23 socat[90844] E sendto(5, 0x5d3cdaa2b000, 8, 0, AF=2 192.168.0.2:8000, 16): Network is unreachable
# # Testing broadcast
# socat - udp-sendto:192.168.0.255:8000,broadcast <<< "Message"
# # Worked
Here is a trick that has been tried and tested over the years: Install another distro, and use that to install Arch. This way, you can rely on an already working linux distro till your Arch install works the way you want.
I was thinking along the lines of
Plenty of libraries can build the XML using structs/classes. e.g. with serde:
//Data type for row
#[derive(serde::Serialize)]
pub struct Foo {
pub status: String,
pub name: String,
}
//Example row
let ent = Foo {
status: "paid".into(),
name: "bob".into(),
}
//Example execution
sqlx::query(&serde_xml_rs::to_string(&InsertStmt{
table: "foo".into(),
value: &ent,
})?).execute(&conn)?;
Or with jackson-dataformat-xml:
//Data type for row
public class Foo {
public string status;
public string name;
}
//Example row
Foo ent = new Foo();
foo.status = "paid";
foo.value = "bob";
//Example execution
XmlMapper xmlMapper = new XmlMapper();
String xml = xmlMapper.writeValueAsString(new InsertStmt("foo", ent));
try (Statement stmt = conn.createStatement()) {
stmt.executeUpdate(xml)
}
I don’t do JS (yet) but maybe JSX could also do similar things with XML queries.
No more matching $1, $2, … (or ? for mysql) with individual columns, I could dump entire structs/objects into a query and it would work.
Never tried that, though a quick search got me this: https://superuser.com/questions/1471937/how-can-i-add-a-bcd-boot-entry-for-linux-in-windows-boot-manager-in-efi
