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.
Thanks man, my brain was short-circuited on Testcontainers so I couldn’t write better. Also I am stealing the title.
I don’t get it, how would a database container run your unit tests? And unless you know some secret option to stop the database after, say, it is idle for a few seconds, it will continue running.
The purpose is to test database dependent code by spinning up a real database and run your code against that.
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.
That advertisement would be interpreted as Node C
’s advertisement.
The plan is to treat public keys as node’s identity and trust mechanism similar to OpenPGP (e.g. include any node key signed by a master key as a cluster member)
Right now, none of the encryption part is done and it is not a priority right now. I need to first implement transitive node detection, actually forward packets between nodes, some way to store and manage routes, and then trust and encryption mechanisms before I’d dare to test this stuff on a real network.
The UI is desktop only for now, I’ll make the mobile UI some day.
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…
I don’t know either, but from what I know, bureaucracy and corruption is often a result of bad organizational structure. Some “designated officer” raises a finger which gets approved by the Secretary who is appointed by the minister who is appointed by the PM who is nominated by the Lok Sabha, and we lose yet another privacy protecting service. I think we should have more direct control in these matters.
For now, if we cannot expect a proper functioning web, they cannot expect stability under their seats. Vote them out.
They never will, we have to vote them out.
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.
Hmm… Maybe I should adjust my priorities.
I was confused for a moment, because intuitively a CPU fan would look in the same direction as it blows air, so it should look into the heatsink. The fan looking away from the heatsink seems weird to me.
Or the owner installed the fan in the wrong direction.
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.
It wants you to put dummy details as fast as you can.
