  • I just kinda vaguely name them after what they do and how big they are:

    smol: my tiny little 2 bay Synology NAS that I’m no longer using
    medium: my R620 with 4x 18TB drives that is my current NAS (medium, because it’s larger than my previous NAS). Is also a k3s worker and provides NFS PVCs.
    big: my old full-tower gaming rig that’s a k3s worker and runs my Home Assistant VM
    molecule: my current mini-ITX gaming rig and primary computer, also serves as the k3s master node and runs a lot of my home automation stuff. I think I picked molecule because it’s REALLY tiny (it’s in a Dan Cases A4v2, I think?) and it has a bunch of small stuff running on it (containers and pods)
    monolith: my old T440p laptop. It’s a large, black, featureless slab that doesn’t do much
    slab: my new Framework 13 laptop. I just kinda looked at it and said, “that’s a nice slab of metal”

    All of the above running Linux. I tinkered with Ubuntu for the NAS (because I heard Ubuntu was good at ZFS), but I still absolutely hate Ubuntu, so it’s all Arch Linux.



  • PART 4.

    You expect a file transfer program to reliably and faithfully transfer your files, byte-for-byte, from one system to another. FTP spits in your face and shits on your chest. You know how Linux uses LF (i.e. \n) for newlines and Windows uses CRLF (i.e. \r\n) for newlines? Pretty annoying, right? Well, FTP’s ASCII mode will automatically rip off those \r characters for you! Sounds pretty sweet, right? Fuck no it’s not. All of the sudden, your file checksums have changed. If you pass the same file back to a Windows user with a different and more sane file transfer system, then they get a broken file because FTP didn’t mind its own fucking business. If you have a CRLF file and need an LF file, just explicitly use dos2unix. Wanna go the other way? unix2dos. The tool has been around since 1989 and it’s great.

    Now, what if you’re not transferring text, but instead are transferring a picture of a cute cat? What if your binary data happens to have 0x0D0x0A somewhere in it? Well, ASCII mode will happily translate that to 0x0A and fucking ruin your adorable cat picture that you were going to share with your depressed significant other in an attempt to cheer them up. Now the ruined JPEG will remind them of the futility of their situation and they’ll slide even deeper into cold emptiness. Thanks, FTP.

    You can tell your client to use binary mode and this problem goes away! In fact, modern clients do this automatically so your SO gets to see the adorable fuzzy cat picture. But let’s just stop and think about this. Why use a protocol that is dangerous by default? Why use a protocol that supports no form of security (unless you’re using fucking godawful FTPS or FTP over SSH)? Why use a protocol that is so broken by design that small business hardware has been designed to try to unfuck it? Is it faster? I mean, not really. SFTP has encryption/decryption overhead, but your CPU is so fast that you’d need to transfer at 25+ Gb/s to notice it. Is it easier? Fuck no it’s not easier, look at all of the stupid footguns I’ve just mentioned. Is it simpler? The line protocol is simple, but so is HTTP, and HTTP has a much simpler control flow path (merging the data and control planes is objectively the right thing to do in this context). And shit, you want a simple protocol for cases where you don’t have a lot of CPU power? Use fucking TFTP. It’s dogshit, but it was intentionally designed to be dogshit so that a fucking potato could receive data with it.

    There is no task that is currently being done with FTP that couldn’t be done more easily, more securely, and more quickly with some other protocol (like fucking SSH and SFTP, which is now built into fucking Windows for god’s sake). Fuck FTP.


  • PART 3.
    They made their STUPID MODEMS FUCK WITH THE FTP PACKETS. I have personally experienced this with Comcast Business. The stupid piece of shit DOCSIS modem they provide intercepts the FTP packet from your server saying “oh, connect to this address: x.x.x.x:44010” and they rewrite the fucking address to the public IP. There is no way to turn just this horse piss off. Now, for average business customers, this probably saved Comcast a bunch of money in support calls. However, if you’re using the so-called bridge mode on that degenerate piece of shit-wrapped-silicon (where rather than allowing the modem to give you a DHCP address, you just configure your system to have one of the addresses in the /29 space and the modem detects that and says oh okay don’t NAT traffic when it’s going to this address, just rewrite the MAC and shunt it over the right interface), then something funny happens. The modem still rewrites the contents of the packet, but it uses the wrong fucking IP address! Because the public IP that your server is running on is no longer available to the modem, the modem just chooses another fucking address. Then, the client tries to connect to 1.2.3.5 instead of 1.2.3.4 where your server is listening, the modem says “hey I’m 1.2.3.5 and you can fuck off, I’m dropping your SYN for port 44010”, and I get an angry call from the client asking why they can’t download their files using this worthless protocol. I remember having a conversation like this:

    Me: “Just use SFTP on port 22!”
    Client: “No! FTP is faster/more secure/good enough for my grandfather good enough for me/corporate won’t allow port 22.”
    Me: “Comcast is fucking me right now. What if we lied and served SFTP over port 21?”
    # we try it
    Client: “It’s not working! I can’t even connect!”

    I couldn’t connect either. I couldn’t connect to anything. Trying to do SFTP over port 21 caused the stupid fucking modem to CRASH.

    Are you starting to see what the problem is? It’s like Microsoft preserving bugs in Windows APIs so that shitty software doesn’t break, and then they end up doing crazy gymnastics to accomodate old shit like the Windows 8 -> Windows 10 thing where they couldn’t use “Windows 9” because that would confuse software into thinking it was running “Windows 95” or “Windows 98”. FTP has some bugfuck crazy design decisions that we’ve collectively decided to just “work around,” and it leads to fucking gymnastics.

    Speaking of bugfuck crazy design decisions, FTP’s default file transfer mode intentionally mangles data!

  • PART 2.

    NAT, much like the city of Phoenix, is a monument to man’s arrogance. Fuck NAT and fuck FTP. If your FTP server is listening directly on a public IP address hooked up directly to a proper router, then none of this applies. If you’re anything like me, the last company I worked for (a small startup), or my current company (many many thousands of employees making software you know and may or may not hate, making many billions of dollars a year), then the majority of your servers are living in RFC1918 space. Traffic from the internet is making it to them via NAT (or NAT with extra steps, i.e. L4 load balancers).

    A request comes in for $PUBLIC_IP TCP port 21 and is forwarded to your failure of a boxen at 10.0.54.187. Your FTP server is a big stupid idiot and doesn’t know this. It thinks that it’s king shit and has its own public IP address. Therefore, when it’s deciding what ADDR:PORT it’s going to tell the stupid FTP client to connect to, it just looks at one of the adapters on the box and says “oh, I’ll tell this client on the internet to connect to 10.0.54.187:44007” and then I fucking cry. The FTP client is an idiot, but the IP stack on the client’s home/business router is not and says “oh, that’s an address living in RFC1918 space, I shouldn’t send that out over the internet” and they don’t get the results of their LIST.

    So, how do you fix this? Well, you fix it by not using FTP. Use SFTP USE SFTP USE SFTP FOR GOD’S SAKE. But since this world is a shit fucking place, you have two options. The best option is to configure your FTP server to lie about its IP address. Rather than being honest about what a fool it is, you can tell it to send your public IP address to the client rather than the network adapter IP address. Does your public IP address change? Fuck you, you get to write a daemon that checks for that shit, rewrites your FTP server config, and HUPs the bastard (or SIGTERMs it if your server sucks and can’t do a live config reload).

    Let’s say that you don’t want to do that. Let’s say you work at a small company with a small business internet plan that gives you static IPs but a shitty modem. Let’s say that you don’t know what FTP is or how it works and your boss told you to get it set up ASAP and it’s not working (because the client over in Bendoverville Arkansas is being told to connect to a 10.x.x.x address) and it surely must be your ISP’s fault. So you call up Comcast Business/AT&T/Verizon/Whoeverthefuck and you complain at their technicians for hours and hours, and eventually you get connected to a human that knows what the problem is and tells you how to configure your stupid FTP server to lie like a little sinner. The big telco megacorps don’t like that. They don’t want to waste all those hours, and they don’t want to hire too many people who can figure that shit out because it’s expensive. You wanna know what those fucking asshole companies did?

  • I’d like to interject for a moment. What you’re referring to as FTP is, in fact, smelly hot garbage.

    For context, I wrote this while waiting for a migraine to pass. I was angry at my brain for ruining my morning, and I like to shit on FTP. It’s fun to be hyperbolic. I don’t intend for this to be an attack on you, I was just bored and decided to write this ridiculous rant to pass the time.

    I must once again rant about FTP. I’ve no idea if you’re serious about liking it or you’re just taking the piss, but seeing those three letters surrounded by whitespace reminds me of all the bad things in the world.

    FTP is, as I’ve said, smelly hot garbage, and the infrastructure built to support FTP is even worse. Why? Well, one reason is that FTP has the most idiotic networking model conceivable. To see how crazy it is, let’s compare to a more sane protocol, like HTTP (for simplicity’s sake, I’ll do HTTP/1.1). First, you get the underlying transport protocol stuff and probably SSL. The HTTP client opens a connection from some local ephemeral port to the destination server on port 80/443/whatever and does all the normal protocol things (so syn->synack->ack and Client Hello -> Server Hello+server cert -> client kex+change cipher -> change cipher -> encrypted data). FTP does TCP too! Same same so far (minus SSL, unless you’re using FTPS). Next, the HTTP client goes like this:

    GET /index.html HTTP/1.1
    Host: www.whatever.the.fuck
    # a bunch of other headers
    
    

    and you know what fucking happens here? The fucking server responds with the data and a response code on the same goddamn TCP connection. You get a big, glorious response over the nice connection you established:

    200 OK
    # a bunch of headers and shit
    
    HERE'S YOUR DAMN DATA NERD
    
    

    So that’s nice, and the client you’re using to read this used that flow (or an evolution of that flow if you’re using HTTP/2 or HTTP/3). So what does FTP do? It does one of two really stupid things depending on whether you’re using active or passive mode. Active mode is the default for the protocol (although not the default for most clients), so let’s analyze that! First, your FTP client initiates a TCP connection to your server on port 21 (by default), and then the server just sends this:

    <--- 220 Rebex FTP Server ready.
    
    

    ok, that kinda came out of nowhere. You’re probably using a modern client that saves you from all of the godawful footguns, so it then asks the server what it supports:

    ---> FEAT
    <--- 211-Supported extensions:
    <---  AUTH TLS;SSL;
    <---  CDUP
    <---  CLNT
    # A whole bunch of other 4 letter acronyms. If I was writing an FTP server, I'd make it swear at the user since there are a lot of fun 4 letter words
    
    

    There’s some other bullshit we don’t care about right now, although highlights include sending the username and password in plain text. There’s also ASCII vs binary mode. WE’LL GET BACK TO THAT. :|

    So then we want to do a LIST. You know what happens in active mode? Your computer opens up some random fucking TCP port. It then instructs the FTP server to CONNECT TO YOUR GODDAMN COMPUTER. Your computer is the server, and the other side is now the client. I would post a more detailed overview of the FTP commands, but most servers on the internet disable active mode because it’s a goddamn liability. All of the sudden, your computer has to be internet facing with open firewall ports, and that’s just a whole heap of shit.

    I’m probably not blowing many minds right now because people know about this shit. I just want to mention that this is how FTP was built. The data plane and control plane are separate, and back in 19XX when this shit was invented, you could trust your fellows on ARPANET and NAT didn’t exist and sure HAM radio operators here’s the entire goddamn 44.0.0.0/8 block for you to do packet switched radio. A simple protocol for simple times, back before we knew what was good and what was bad.

    So, active mode sucks! PASV is the future, and is the default on basically all modern clients and servers! Passive mode works exactly the same as the above, except when the client goes to LIST, the server opens some random TCP port (I’ve often seen something like 44000-44010) and tells the client, “hey you, connect to 1.2.3.4:44000 to get you your tasty data.” Sounds great, right? Well, there’s a problem that I actually touched on in my last paragraph. Back when this dogshit was first squeezed out in the 70s, everyone had a public address. There were SO MANY addresses! 4 billion addresses? We’ll never use all of those! That is clearly not the case anymore. We don’t have enough addresses, and now we have this wonderful thing called NAT.

  • There’s always Termux and whatever you can install there. That sounds silly, but when I download from my phone, I do it using aria2c in Termux. It works great, and everything (AFAIK) is FOSS. zsh + fzf history completion/file finding (<c-T> is a godsend) makes it possible to use a CLI on a phone without going crazy. Only really works well if you’re already comfortable with the command line, which is definitely a big if. It works really well for me, but I’m one of those weirdos that doesn’t have a graphical file manager installed on their computers.


  • I think my initial read of your comment was wrong (I thought you were saying that the term was fine, which didn’t hold up on my second read where I was paying attention), so I want to clarify by saying what I think you mean. You’re making the point that I should be saying that the statement is racist and that they should consider whether or not they want to use it, not that they are being racist by using it in ignorance.

    Is that right? Because if so, that’s a fair point. More flies with honey than vinegar and all that. I’m normally better about giving people a chance to consider rather than just dictate my beliefs, but I’m sleep deprived and cranky and I think it’s making me act in ways that aren’t aligned with my usual values.

    Edit: and it’s a sign that I need to get off of the Internet for now, since I’m being waaaay more negative than I want to be.

    Yeah, that’s why I wish the community would just use a different term. I’m not a fan of where it came from (Asian people bad asian motorcycle bad), and the arguments where one person says “I’ve been saying it for years,” versus “bro it’s been fucking racist for years,” have gone past the point of a beaten and dead horse and into the realm of a fine mist of blood, fat, muscle, and viscera. Like, I just don’t understand why people are attached to it, it’s such a weird hill to die on. If it’s a matter of having a term that people outside of the community wouldn’t immediately understand, then I’m sure a different word could be found.

    Edit: christ, I was not familiar with its usage in the 1930s. What a mess… Also, really loving the section on its Korean war usage, that’s just great. Thanks for the link, it reaffirms my desire for the community to just use a different goddamned word.


  • The only thing that comes to me is that someone who was really into tuning/spiffing up Japanese cars was involved in the community early on. I’ve always found it weird, and I’d honestly kinda prefer to just use “theme” or “spiff” or one of the many other words that the Godfucked curse of the Earth that is the English language provides for the purpose.


  • I think the OP clearly doesn’t like that they have this reaction (as someone else pointed out, and as you acknowledged). I think I understand why you might think this came from a lack of empathy. You like kids, what could be wrong with them acting like kids do? Sure, they’re loud, but it’s not that big of a deal! This person must have no empathy, because if they did, they’d be fine with it. People with no empathy are psychopaths, so OP must be a psychopath.

    I think you’re already starting to see what’s wrong with that line of reasoning, which I really appreciate. Just to restate it here, the OP probably doesn’t hate children, they just have problems with overstimulation (possibly misophonia or autism spectrum stuff). Not everyone has experienced overstimulation, but I can assure you that at best, it makes you reaaally cranky. Feelings of rage aren’t surprising to me. If the OP wants, there are coping strategies and things they can do to help themselves in certain circumstances, but they’re not wrong or bad. Their brain just works differently from other folks, and this is one of the effects of that.

    It’s not society’s job to fix this (because kids have the right to be kids, and kids are kinda loud sometimes, even if you’re trying to teach them to be mindful of their volume), but I think that it’s generally good to try and show some empathy, or at least ask questions in good faith if you don’t understand well enough to empathize.

    I’d implore you to communicate with a bit more intent. Calling someone a psychopath is a pretty serious thing to do! Did you intend to hurt someone’s feelings that much? Or were you just confused and a bit angry, and came to that conclusion in haste? There’s a person on the other side of this conversation who has feelings, and they’re asking here for help. They’re trying to improve themselves, and I don’t think you’d want to say that type of thing to someone who’s just trying to live a better life.


  • I’ve been incredibly happy with Kagi. All of the listicles and blogspam get shunted off into their own sections. Kagi also seems to do a pretty good job at finding “deep” results. Like, when I want to find out more information about some home automation gizmo, Kagi does a good job of finding some random blog post where someone has torn the gizmo apart and analyzed every strength and weakness it has. I still prefer Google for looking up restaurants and stuff, but I hardly use it anymore. I don’t at all regret the $10 a month I pay to use Kagi.

    Edit: I also like that Kagi lets you define rules. Occasionally I’ll be forced to go to Reddit to get some information (I really try to go elsewhere first). I deleted my account, so I go to new Reddit by default (which I hate). I don’t want to add an extension to redirect to old Reddit, but I can just replace the www with old automagically for all Reddit search results. Works great.



  • As much as I despise Oracle and the lawn mower man known as Larry Ellison, I don’t think this is a problem. Oracle also had a lot to do with btrfs, and while that filesystem has problems, they’re not the sort of problems usually associated with Oracle (i.e. rapacious capitalistic practices like patent trolling and suing the fuck out of everyone all the time always). Oracle won’t own XFS, it’s owned by every single person who has ever contributed to that codebase.
