Badabinski

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.

As others have said, the inner child is an incredibly useful metaphor for trauma/therapy. The way your brain reacts to trauma is to basically create a bookmark of you at that time. If you manage to live through the trauma, then clearly, the emotions you felt and the actions you took worked perfectly!

Well, that was probably true in prehistory, but nowadays it’s a big fucking stupid liability. Like, for example, say I’m doing my adult job at $company and my coworker Todd Fuckwit (esq.) says something shitty about suicide that reminds my brain of an old bookmark. All of the sudden, my emotional state is transported back to when Young Badabinski saw the results of a parental suicide attempt and thought it was entirely their fault and Badabinski deserved it (Important note, this is not regular PTSD with vivid hallucinations/flashbacks, this is more about emotions). Now I’m freaking out in the meeting room and abruptly leave because I feel like a 12 year old who has just had their world ended, and escaping us what I did back then.

The way you heal this is to try to create a connection with that bookmark of yourself and then give yourself what you needed back then. Over many therapy sessions, I was able to help young Badabinski realize that none of that was their fault, that they didn’t deserve to see that, and that they should have had the warm and loving care of both of their parents. And you know what? It really fucking worked.

For more chronic cases (like a lot of emotional neglect), your inner child is just kinda… There? Like, the bookmark part of the metaphor breaks down a bit. Your inner child represents the tender emotions that were left unhandled and childhood needs that were left unmet. A lot of my therapy nowadays is helping my inner child feel less deprived and more loved on a day-to-day basis, because if I don’t take care of myself enough in the ways I need, then my brain will pull up the chronic inner child and I’ll be miserable for days/weeks/months. In contrast, the parts of my life where I’ve permanently changed my day-to-day behavior feel so much more fulfilling and wonderful. It’s not just about avoiding the negatives, you end up focusing more on achieving the positive.

I personally like describing it as a metaphor. I was a bit of an angry skeptic when I was younger (due to the aforementioned parent moving to a bunch of new-age crystal healing shit after their recovery and then trying to push it on me when I absolutely did not believe in the validity of those methods), so I didn’t like how metaphysical and “touchy-feely” an inner child felt. I’m no longer skeptical of this idea am a much more emotionally liberated person. I often think of my inner child as if it were an active presence in my mind (it feels more effective to do so for me). It took a lot of time time for me to reach that place. I believe that explaining it as a metaphor will get through to people who would otherwise spurn the concept. Metaphor or not, I still want to help the little human that is past me, and I’d love to be able to drink a potion that would let me talk to that twelve year old.

I’m glad that my grumpy migraine ramblings brought someone some joy!

:( I’m sorry to hear that. Well, for Android there’s MaterialFiles, which is fully FLOSS and supports FTP, SFTP, and SMB. Not sure about iOS, but I imagine there are options there.

I hope that your journey through life becomes a little less rocky.

There are definitely a lot of good options out there. What are you using right now for regular old FTP? The odds are actually pretty good that it already supports SFTP. A lot of file management applications do both and lump them together, even though they’re completely different protocols (sftp is from the late nineties).

If it doesn’t, then I don’t know what OS you’re using, so I’ll just recommend options for the big 3. For Windows, there’s WinSCP. For MacOS there’s Cyberduck. Most file managers on Linux distros let you just type sftp://me@wherever in the navigation bar, meaning you get a totally seamless experience with the rest of your FS.

EDIT: or, you can use sshfs-win on Windows and have your remote filesystem show up as a regular ol’ drive, just like SMB. MacOS and Linux have sshfs, and I know there are GUIs wrapping sshfs on those platforms. I personally use sshfs at home and it’s great (although no GUI wrapper, I’m a weirdo who doesn’t use a graphical file manager at all).

You should be able to just use ssh/sftp. There are lots of great clients, and you can absolutely still use usernames and passwords, no public/private key stuff required. You can even use ssh and scp right from powershell on Windows boxen if you’re so inclined. There’s winscp, and if you want filesystem mounting, there’s this: https://github.com/winfsp/sshfs-win
For macos and Linux, the options are far more plentiful.

Edit: there’s also file pizza, which is a file transfer thingy with no middle man that’s open source, although it’s not copyleft AFAICT: https://github.com/kern/filepizza
and similar tools. Not really what you’re after, I just think it’s neat.

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?

Continued in part 3.

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.

Continued in part 2.

For Linux applications that respect XDG? Sure. There are plenty that don’t because they either predate that specification, or they just don’t care. Linux filesystems are generally much faster at executing reads on many small files, meaning fast search tools like ripgrep and fd make it so I don’t really have to care. They’ll run through my whole $HOME in 5 seconds flat. There’s also stuff like locate, although I don’t like maintaining an index. SSDs are so damn fast that I can just rg --hidden --glob '*.toml' 'the_setting_i_want_to_change' ~/ whenever I want.

Huh, interesting! Sounds like it’ll be perfect for OP.

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.

Eating this stuff would be about as bad as eating any regular cat litter that uses Fuller’s earth as the primary absorbent. The extra special ingredient (powdered quartz) is effectively nontoxic when ingested. The real issue is the chronic exposure to very fine silica dust.

Edit: to clarify, I do not believe that it would be safe for humans or animals to use this as cat litter. Just realized that this comment might have been taken as a “well akshually it’s fine.” It is not fine, silicosis is a dreadful condition.

So I’d like to chime in. It looks the the two primary ingredients for ZEP-o-zorb are Fuller’s earth and powdered quartz.

First, Fuller’s earth. This is good stuff! It’s actually often used as an industrial absorbent for chemical spills (the purpose of ZEP-o-zorb), as well as in some types of cat litter. It totally makes sense why this stuff would work well for you, and I understand why you’ve been using it for a year. It’s perfect for the task and has basically no downsides.

Now, about the powdered quartz… Chemically known as silicon dioxide. It’s often refered to as silica. Silica is also good stuff! It’s in concrete, it’s the main component of glass, and of particular interest for your application, it’s very good at absorbing volatile organic smelly stuff. Seems perfect, right?

Unfortunately, powdered quartz has a downside. When it’s in a very fine powder, it produces a lot of dust. This silicon dioxide dust is incredibly harmful to your lungs. Long-term exposure to silicon dioxide dust results in silicosis, which is a really serious illness that kills tens of thousands of people every year. Inhaling that dust can also give you lung cancer, lupus, rheumatoid arthritis, or other autoimmune disorders.

I totally understand why you felt that this product was a great option! I don’t doubt that it serves as an absolutely excellent cat litter. I had two kitties that took the smelliest shits, and I was always searching for ways to fix that (either through diet, litter, stress reduction, or other things). I also understand how upsetting it can be to share something with people and be met with disbelief, denial, and accusations. However, I really want to urge you to look past all of that and reconsider your use of this product. The silica dust is practically invisible and tasteless, and it had the chance to cause you many years of problems. You and your cat deserve to be healthy.

You joke, but using air dropped bombs to put out fires is a tactic that’s been used for quite a while. probably not the best thing to do next to a site with nuclear materials on-hand, but it’s absolutely been done before.

Game devs specialize in writing code that gets displayed on a GUI. They also have to learn how to do scripting and some decision tree stuff for AI, but from day 1, they’re writing for a GUI. Plus, game engines contain a tremendous amount of code that makes it very fast to make GUI. That game engine is huge and complicated and you have to spend a bunch of timing learning how the hell it all works. Software devs outside of the games industry haven’t done that, and it would increase the size of a small and simple script from 200 lines of code and a few kilobytes to thousands of lines of code and multiple megabytes or gigabytes.

I’m a senior software dev and have built a shitload of tools and scripts that are command line only. I’ve been told that I’m a really great developer, and I have a knack for figuring things out, even when there’s no documentation.

For the life of me, I absolutely cannot wrap my head around frontend shit. Like, I can do markdown just fine. HTML? CSS? Any of the popular frontend UI frameworks? I just seem to have some sort of conceptual and motivational block that prevents me from figuring out how to make those accursed fucking frontends.

It’s such a different form of software development. I wish I could wrap my head around it, but I’ve accept that I’m not ever going to be a frontend dev. I just write server side stuff and scripts. I apologize if you ever have to use my software :(

I’m much less worried about human piloted craft. It’s very difficult to program complex decision making and discernment. The astronauts present in the first landers will have been intensively trained in how to avoid catastrophe and will likely be able to come up with solutions on the fly if unanticipated things happen. Still dangerous, but hopefully less so.

It will be much easier to land completely automatically once we have landing pads, radar tracking, and other infrastructure present on the surface. It’s just hard to land a robot on an airless moon with a bunch of rocks and hills and shit everywhere.

I tip 20% or $5 on takeout orders, whatever is larger (provided nothing goes terribly wrong). I have the means, and I remember how much I fucking hated working in retail. I depend on these people to feed me and I appreciate that they’re willing to do it (especially with how poorly they get treated at times). If I can make someone’s day better then it’s worth it to me.

That being said, I hate tip culture and wish that the laws in my country around tipping would change. This is getting off topic now (since I think that the people doing takeout orders aren’t subject to this), but it’s absurd that we let restraunts pay $3.50 an hour if someone is making the rest of the minimum wage in tips. If I tip someone, I want it to be because I really appreciate what they did. I don’t want to be paying their wages, they should be receiving a livable wage no matter what. I know that refusing to tip won’t change that, so I just go along with it.
