It’s insane to me that gitflow won over TBD and Continuous Integration to the point that this is now considered an extreme position. Not all projects are open source with many remote collaborators.
That would allow for like, 2 trillion devices? Feels like a bandaid, my dude. Next you’re gonna suggest a giant ice cube in the ocean once a year to stop global warming.
Hurricanes cannot cross the equator. The equator is an imaginary line, and hence has zero mass. We can end every hurricane using zero point zero energy (0.0).
I thought it was pretty clear with me adding 13.37 that I was making a joke, the earlier post spoke about how just adding one octet would still be too few addresses, so I joked about adding one more octet.
You can use a ULA if you want to. That’s essentially the IPv6 equivalent of a private IP.
Why though? Having the same IP for both internal and external solves a bunch of issues. For example, you don’t need to use split horizon DNS any more (which is where a host name has a different IP on your internal network vs on the internet). You just need to ensure your firewalls are set up properly, which you should do anyways.
You could follow this logic and add 2 alphanumeric digits before 4 numeric octets. E.g. xf.192.168.1.1
This would at least keep it looking like an IP and not a Mac address. Another advantage would be graceful ipv4 handling with a reserved range starting with “ip” like ip.10.10.10.1
Oh yeah, great, let’s change the fundamental protocol on which all the networks in the world are based. Now two third of the devices in the world crashed because you tried to ping 192.168.0.0.1
Please don’t. Use regex to find something that looks like an IP then build a real parser. This is madness, its’s extremely hard to read and a mistake is almost impossible to spot. Not to mention that it’s slow.
Just parse [0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3} using regex (for v4) and then have some code check that all the octets are valid (and store the IP as a u32).
Fuck that, if for whatever reason I’m writing an IP validator by hand I’m disallowing leading zeros. Parsers are very inconsistent, some will parse 010 as 10, others as 0o10 == 8 (you can try that right now with a POSIX ping). Talk about a footgun.
True enough for database or dictionary storage, but a lot of times things get implemented in arrays where you still wind up with two copies of the same uint32.
Because 1.2.3.4 and 1.02.003.04 both map to the same number.
But 10.20.30.40 and 010.020.030.040 map to different numbers. It’s often best to reject IPv4 addresses with leading zeroes to avoid the decimal vs. octal ambiguity.
Holy hell yeah you did. How would you go about doing that in a single expression? A bunch of back references to figure out the country? What if that’s not included? Oy.
You wouldn’t. It’s not possible. Which is what I told them.
And why would you want to? Legally if you change the given address, and it fails to get delivered - that is on you. Not them.
Some countries have addresses that are literally ‘Last house on the left by the Big Tree. Bumban(Neighborhood). NN (Country)’. Any US Centric validation would fail this but I assure you - mail gets delivered just fine.
The only valid regex is (.+). Maybe add a separate country field (especially because some Americans wholeheartedly believe that the entire world should understand that “foobar, TX” means “foobar, Texas, United States”) (don’t get me started on states whose abbreviations are also ISO country codes).
Unfortunately I guess business people only care about getting fewer support calls for missing shipping details, not correctness or a couple of calls from customers who live in the boonies. Then the proper answer is a form with a bunch of fields… which Americans will inevitably fuck up by making the “State” field mandatory despite most countries not having an equivalent.
What I’d really do is use one of those services that automatically fill on the address using google maps or whatever. Not perfect, probably not free, but a whole lot less work for presumably way fewer PEBCAKs from customers.
If you’re using one of those services then PLEASE allow manual entry / override because I’ve had forms like that which I were blocked from filing in because it didn’t acknowledge that my address existed.
my website’s backend is made with bash, it calls make for every request and it probably has hundreds of remote arbitrary code execution bugs that will get me pwned someday, it’s great
edit: to clarify, it uses a rust program i made to expose the bash scripts as http endpoints, i’m not crazy enough to implement http in bash
it behaves like a static file server, but if a file has the others-execute permission bit set it executes the file instead of reading it
it’s surprisingly nice for prototyping since you can just write a cli program and it’s automatically available over http too
i thought it was neat how php lets you write your website’s logic with the same directory tree pattern that clients consume it from, but i didn’t want to learn php so i made my own, worse version
I’ve taken some precautions, it’s running in a container as an unprivileged user and the only writable mount is the directory where make writes rendered pages, but i probably should move it into a vm if i want to be completely safe lol
I know about the CGI standard, but mine does things a little differently (executable files don’t just render pages but also handle logging, access control, etc. when put in special positions within a directory), so I still think it was worth the afternoon i spent making it.
Remember, when we abbreviate an ipv6 address all leading zeros are reduced to a single 0.
E.g
0003 would just become 03
When there are geoups of 4 zeros these can be represented as a single 0 or as a double colon ::
But we can only use the :: once so when summarizing an address containing multiple groups of 4 0s one after the other they can all be abbreviated to a single ::
Eg
fe80:0000:0000:0000:0210:5aff:feaa:20a2 would become fe80::210:5aff:feaa:20a2
Therefore it is perfectly valid to abbreviate an address of 0000:0000:0000:0000:0000:0000:0000:0000 /0 to just ::/0
Did you know you can zip entire Python project into single file and make it executable? Quite a neat feature. Shove all dependencies, modules and assets in there and voila. Single file python application.
