L95[15:29:09] <Forec​aster> @S3 works much better with a 1M resistor it turns out
L96[15:30:40] <S​3> I knew it
L97[15:31:28] <Forec​aster> the calculation for the coil doesn't work out though, and I don't see why
L98[15:31:29] <Forec​aster> https://discordembeds.pc-logix.com/live/1697643089511.png
L99[15:31:32] <S​3> I mean I had a 90% certainty
L100[15:31:43] <S​3> Uh
L101[15:31:52] <Forec​aster> I'm pretty sure there's no 25V on the multimeter
L102[15:32:13] <Forec​aster> it looks like it's off by an order of magnitude, but I think the values are right...
L103[15:32:14] <S​3> No you just need to set it above 25V
L104[15:32:23] <S​3> So like if there's a 50 or something for example
L105[15:32:30] <Forec​aster> what?
L106[15:32:47] <S​3> I mean you already know this, it just moves the decimal point that's all
L107[15:33:01] <Forec​aster> I mean that the multimeter is measuring 2.2V, but the math shows it should read 25V
L108[15:33:14] <S​3> Ohh
L109[15:33:31] <S​3> I thought you meant Theres no 25V seetting on the dial
L110[15:33:45] <Forec​aster> I'm fortunately not *that* stupid
L111[15:33:54] <S​3> Right I was confused
L112[15:34:02] <S​3> I was like there's no way you didn't know that 🙂
L113[15:34:16] <S​3> But I wasn't going to laugh either
L114[15:34:47] <Forec​aster> I'm using a 25mA led lightbulb, and a 1M resistor, which is what I've plugged into the formula from the datasheet, but something's gotta be wrong
L115[15:34:54] <Amanda> %choose cubes or continue staring at editor like it kicked your me
L116[15:34:55] <MichiBot> Ama​nda: If I've learned anything in life it's that you always pick "cubes"
L117[15:35:19] <S​3> Are you also including the voltage drop of the led?
L118[15:35:51] <Forec​aster> I don't know what that would be
L119[15:36:06] <Forec​aster> could that account for 22 something volts?
L120[15:36:08] <Forec​aster> I have no idea
L121[15:36:46] <S​3> You can use Kirchoff law of voltage actually. I don't think you need to worry about it. Your math should be working
L122[15:36:48] <Forec​aster> I guess I could measure the voltage drop if I really wanted to
L123[15:37:06] <S​3> The one thing I can think about is if it's actually measuring 22 volts and your decimal point is off
L124[15:37:48] <S​3> Change that dial to 200 instead of 20 maybe
L125[15:37:59] <S​3> See what you get then
L126[15:38:14] <Forec​aster> The decimal point is visible on the display though
L127[15:38:50] <Forec​aster> The only difference between 20 and 200 is the decimal precision
L128[15:39:05] <S​3> Yeah but if you are measuring > 20 volts and you have it set to 20 it can cause the meter to show the decimal point in an odd place
L129[15:39:39] <S​3> Because the voltage measured will be out of the tolerance zone
L130[15:40:17] <Forec​aster> https://discordembeds.pc-logix.com/live/1697643616967.jpg
L131[15:40:38] <Forec​aster> Pretty sure this meter doesn't do that
L132[15:41:06] <Forec​aster> If the measurement is off the scale it shows 0L
L133[15:41:12] <S​3> Cool. That theory is debunked. Yay
L134[15:41:27] <S​3> Yeah some do
L135[15:41:39] <S​3> I have some older meters that do weird things
L136[15:41:55] <Forec​aster> https://discordembeds.pc-logix.com/live/1697643715377.jpg
L137[15:41:59] <S​3> They like wrap around in the register or something and the decimal does weird shit on mine
L138[15:42:09] <S​3> That's nice.
L139[15:42:16] <S​3> I wish mine was that smart
L140[15:42:31] <Forec​aster> I'd guess it's the voltage drop then probably
L141[15:43:30] <S​3> Kirchoff law, if you don't know it by the way is just that all voltages, and all current entering and leaving any node on your circuit will always sum to 0
L142[15:44:01] <S​3> So like, if you know that a voltage or current is in one half of the circuit you know what it is in the other half
L143[15:44:38] <Forec​aster> I know that the input voltage is 230V
L144[15:44:43] <S​3> Example, you have a 10 volt battery and two resistors and one resistor measures at 4V, that means the other resistor has to be 6.
L145[15:45:15] <S​3> All of the components in series has to measure to the total voltage across the circuit
L146[15:45:18] <Forec​aster> ah, you meant the voltage across the limiting resistor
L147[15:46:03] <Forec​aster> except that's in paralel
L148[15:46:14] <S​3> The led has its own resistance too. The current limiting resistor included. Do you have a schematic drawing of this circuit?
L149[15:46:43] <S​3> I'm just mentioning this in case you think you have some oddly unexplained voltage
L150[15:46:47] <Forec​aster> the led bulb is technically not in the circuit though
L151[15:47:10] <Forec​aster> it's in the primary circuit that goes through the coil (ie what is being measured)
L152[15:47:37] <Forec​aster> the coil circuit only has the limiting resistor and the rectifier and the meter
L153[15:48:14] <Forec​aster> I'll draw it, hold on
L154[15:48:43] <S​3> You don't have to, I was just thinking I'm throwing ideas that area probably not helping
L155[15:49:04] <Mim​iru> https://tenor.com/view/electroboom-electroboom-good-good-gif-25753968
L156[15:49:04] <Mim​iru> A rectifier you say?
L157[15:49:56] <S​3> I have this in brain idea of what your circuit looks like because it's simple, but that's not always helpful
L158[15:51:30] <S​3> Either way I definitely apologize that I'm probably doing the opposite of helping, doesn't matter that I went to school for EE & CE lol. That was a long time ago.
L159[15:53:05] <S​3> A full bridge rectifier!!!
L160[15:56:23] <Forec​aster> https://discordembeds.pc-logix.com/live/1697644583140.png
L161[15:56:32] <Forec​aster> here it is, in all it's paint glory
L162[15:57:16] <Forec​aster> considering I have done none of that you're leagues ahead of me 😛
L163[15:57:56] <Forec​aster> and you definitely helped when you said to try a bigger resitor, it got me the result I wanted
L164[15:58:14] <Forec​aster> all that's left is to hook it up to the pi and see it if catches fire or not
L165[15:59:29] <S​3> That's actually a way better drawing than expected. I couldn't make straight lines like that ahahaha
L166[15:59:54] <Mim​iru> paint has a line tool :P
L167[16:00:17] <S​3> Where's your current limiting resistor in this
L168[16:00:30] <Mim​iru> above the rectifier, below the coil
L169[16:00:38] <S​3> Yeah but I get sidetracked trying to make the lines straight
L170[16:00:39] <Forec​aster> oh, yeah, I forgot to label it
L171[16:01:24] <S​3> Well that's just a sampling resistor for a test point
L172[16:01:57] <Forec​aster> https://discordembeds.pc-logix.com/live/1697644916972.png
L173[16:01:59] <Mim​iru> looking at the previous breadboard circuits, that's the only resistor
L174[16:02:04] <Forec​aster> yes
L175[16:02:13] <S​3> It doesn't really do any current limiting it's just providing a potential difference.
L176[16:02:17] <Forec​aster> the test point is the output of the rectifier
L177[16:02:43] <S​3> Interesting
L178[16:03:32] <Forec​aster> the multimeter has it's own limiting resistance
L179[16:08:01] <Forec​aster> the most fun part of this is once everything is working I have to put it together in some way that it all fits inside a light switch socket with some room left over (for the normal wiring)
L180[16:08:26] <Forec​aster> this is mainly why I got an IC rectifier, because I could have easily made one, but it would have been bigger
L181[16:17:57] <S​3> Yeah I don't know what's popular now but a lot of times it's 1M ohm
L182[16:18:13] <S​3> I think my is ilioscope is the same

L219[19:00:11] <S​3> I was testing some things
L220[19:00:19] <Forec​aster> That's the website I use
L221[19:00:23] <S​3> So like
L222[19:00:28] <S​3> falstad is great for ideal circuits
L223[19:00:46] <S​3> I really like every circuit but I wish it had a more friendly UI
L224[19:00:50] <S​3> you can't type in values
L225[19:01:08] <S​3> By the way, that transformer is actually a current controlled voltage source.
L226[19:01:33] <S​3> https://discordembeds.pc-logix.com/live/1697655693179.png
L227[19:01:41] <S​3> I just punched in your equation on your data sheet
L228[19:01:57] <Forec​aster> Huh
L229[19:02:22] <S​3> I didn't think about the fact though that that resistor value gives you like a 1.6 kV jump
L230[19:02:32] <S​3> Oh wait
L231[19:02:39] <S​3> its because I have a 75Ohm load on the AC line XD
L232[19:02:44] <S​3> No wonder
L233[19:04:33] <S​3> I'm so used to adding a 75Ohm resistor there for line impedence
L234[19:05:15] ⇨ Joins: lunar_sam (c44a7f2987@2a00:c70:1:178:170:40:189:1)
L235[19:18:19] <Forec​aster> seems to be a pretty good approximation of the current circuit
L236[19:18:21] <Forec​aster> https://discordembeds.pc-logix.com/live/1697656701133.png
L237[19:22:50] <S​3> Wait why is the LED on the other side of the rectifier?
L238[19:23:34] <Forec​aster> it's where the voltmeter would be
L239[19:24:56] <S​3> This is kindof what I did
L240[19:24:58] <S​3> https://discordembeds.pc-logix.com/live/1697657098379.png
L241[19:25:08] <S​3> the 550 was a calculation of an average LED light bulb in a house
L242[19:25:17] <S​3> so that's assuming a 550Ohm AC load
L243[19:25:50] <S​3> then, a voltage divider brings the transformer down to a reasonable voltage
L244[19:25:55] <Forec​aster> with just a probe instead of the led I get 230V at the output instead
L245[19:25:56] <S​3> those need to be a high resistance by the way
L246[19:26:10] <Forec​aster> which tells me all the resistances are wrong
L247[19:26:26] <S​3> uh
L248[19:26:41] <S​3> You're US right?
L249[19:27:02] <S​3> We're working with 110-130 120V @ 60Hz?
L250[19:27:18] <Forec​aster> no
L251[19:27:23] <S​3> Oh fun
L252[19:27:25] <Amanda> They're actually martian
L253[19:27:27] <Forec​aster> it's 230V
L254[19:27:29] <S​3> LOL
L255[19:27:46] <Amanda> A martian gator to be specific
L256[19:27:54] <S​3> ok, so it's also probably 50Hz
L257[19:28:11] <Forec​aster> yes
L258[19:28:43] <S​3> The LEDs are probably also a different internal resistance too
L259[19:29:11] <S​3> maybe more like 1k
L260[19:31:38] <S​3> You don't need an op amp, but it's a super useful way to near 100% isolate curcuits. That's why there's an op amp with a feedback direct to the inverting input
L261[19:31:43] <S​3> it just puts out whatever voltage comes in
L262[19:32:06] <S​3> but the point is to bring it down to like 2.5 or so volts
L263[19:32:12] <S​3> (the voltage divider)
L264[19:32:39] <Liizzii> what program is it that you guys are using for those circuit diagrams? it looks similar to one I used in school a long time ago if the little dots on the paths animate and i haven't been able to find it since
L265[19:32:53] <S​3> https://www.falstad.com/circuit/circuitjs.html
L266[19:33:25] <Liizzii> ooh it's a website, nice
L267[19:33:32] <Liizzii> think the one i used was logic-something
L268[19:33:39] <Liizzii> but again, this was 10+ years ago
L269[19:34:06] <S​3> It's pretty good for quick things. It's only great for ideal testing though. It doesn't do any temperature based deviation or anything.
L270[19:34:15] <S​3> Probably logicsim?
L271[19:34:36] <Liizzii> sounds like it
L272[19:34:41] <S​3> You might like this site:
L273[19:34:42] <S​3> https://everycircuit.com/app
L274[19:34:51] <S​3> This site is great, except it makes my laptop heat up
L275[19:34:54] <Forec​aster> I used it when I figured out my dc current reversing circuit
L276[19:35:22] <Forec​aster> it's very good for quickly experimenting with simple circuits
L277[19:35:31] <Forec​aster> this more complex stuff is a bit beyond me
L278[19:35:43] <S​3> circuits get really whack in the real world
L279[19:35:56] <S​3> You can plan out a circuit to peform a certain way all day and still have it come out weird
L280[19:36:26] <S​3> Sometimes, you will think you did everything right, and then while testing, you'll be questioning how the hell you are somehow reading a sourcing current on ground, and going, wtf?!
L281[19:37:15] <Forec​aster> This is the polarity switcher https://discordembeds.pc-logix.com/live/1697657835149.png
L282[19:38:24] <S​3> You basically invented an expensive hbridge
L283[19:38:44] <S​3> https://en.wikipedia.org/wiki/H-bridge
L284[19:39:06] <S​3> Used with moptor controls to control direction of motors on robots and stuff we made in high school
L285[19:39:20] <Forec​aster> that's what it was called yeah
L286[19:39:37] <Forec​aster> how'd you make this cheaper than with two transistors?
L287[19:39:53] <S​3> manual switches that we pulled out of a grab bag box
L288[19:39:54] <S​3> so I mean
L289[19:39:56] <S​3> not really cheaper
L290[19:40:08] <S​3> we just flipped them by hand XD
L291[19:40:24] <Forec​aster> right, well that doesn't fit my application 😛
L292[19:41:08] <S​3> We also used these
L293[19:41:10] <S​3> https://discordembeds.pc-logix.com/live/1697658070348.png
L294[19:41:21] <Forec​aster> This is for switching a bi-stable relay (the one that controls the mains circuit in the same system where the current measurement circuit is going)
L295[19:41:28] <S​3> you just send an 8 bit number to the parallel port ona computer and it would turn on/off those motors
L296[19:41:42] <S​3> if you wanted a computer on a robot that is
L297[19:41:48] <S​3> we would duct tape laptops to them
L298[19:41:49] <Forec​aster> that would not fit in a light switch socket unfortunatley
L299[19:41:52] <S​3> haha
L300[19:41:58] <Forec​aster> nor would the laptop
L301[19:42:09] <S​3> These were like, hacky robots the size of your laptop or so but taller with wheels
L302[19:42:18] <Forec​aster> I've seen those
L303[19:42:21] <S​3> Ran on QBASIC
L304[19:42:38] <Forec​aster> not in person, never made one either obviously
L305[19:42:45] <S​3> we built them out of things like plastic electrical boxes taped together or pieces of metal we found
L306[19:42:57] <S​3> It was pretty crude looking
L307[19:43:09] <Forec​aster> I wish I got to do that when I was younger
L308[19:43:24] <Forec​aster> now I could do that, but I don't have time
L309[19:43:32] <S​3> Time is everything 😄
L310[19:43:49] <Forec​aster> though I do get to work with industrial robots instead, so I guess I kinda got there in the end
L311[19:44:33] <S​3> My wife threw a milk out of my nose curve ball the other day when she randomly asked, "If we had kids what would you like to accomplish first?"
L312[19:45:26] <Forec​aster> ah yes, the ambition ender milestone
L313[19:45:45] <S​3> They were waiting for an answer and it was like, uh oh
L314[19:47:09] <S​3> Maybe I should buy a CT transformer and play with it. It could be useful for my own purposes A friend of mine may want to run servers in a rack on my fiber connection, so I need away of logging power usage and for costs.
L315[19:47:31] <Forec​aster> also, it should tell you something about my competency with this stuff with the fact that it took some effort to figure out the construction of an h-bridge, given how they're actually fairly simple
L316[19:48:01] <S​3> Honestly it looks easier on a picture like above than it gets when you're actually doing it. It's easy to get confused.
L317[19:48:20] <S​3> In our robotics courses we had many of us often accidently wired something backwards
L318[19:48:28] <Forec​aster> well I found diagrams of them
L319[19:48:29] <S​3> ended up with either magic smoke or it only moving one direction, etc
L320[19:48:57] <Forec​aster> but it took a certain amount of fiddling with it in falstad to figure out how the transistors went together for it to work the way I wanted
L321[19:49:49] <Forec​aster> I specifically needed two distinct inputs (outputs on the pi) to control each direction
L322[19:49:57] <Forec​aster> and a single output
L323[19:51:00] <Forec​aster> also, one of the few things I dislike about falstad is how some components only go in certain orientations
L324[19:51:25] <Forec​aster> which is why the transistors are placed in such a weird way in the polarity switcher
L325[19:54:54] <Forec​aster> I should take apart one of my light switches and measure the hole before I'm ready to start assembling the first circuit
L326[19:56:35] <S​3> Falstad also does weird things from time to time. I think that perhaps it has a problem determining superpositions to measure from and it freaks out. I never thoroughly tested them and I'm sure the developer is aware and maybe even be a limitation
L327[19:57:02] <Forec​aster> I haven't done anything complex enough to encounter that
L328[20:00:12] <S​3> So earlier when I was drawing that circuit I had an op amp enter a werird state where it was saturating into a square wave and it was bleeding current from the voltage divider, which, op amps have ideally infinite input resistance, though that's not really actually true
L329[20:00:37] <S​3> The solution was to replace the op amp and the load resistor. Just odd
L330[20:05:33] <Forec​aster> Also, I need to find a bigger led bulb and plug it into the circuit
L331[20:05:56] <Forec​aster> dial in the resistance to try to get it to not exceed 3V while still being detectable hopefully
L332[20:20:27] <Amanda> %choose laptopnaptime?
L333[20:20:28] <MichiBot> Ama​nda: I'm going to pretend I didn't hear that.
L334[20:20:40] <Amanda> Laptopnaptime.
L335[21:06:53] <Amanda> %give MichiBot a dream of pair 'a dice
L336[21:06:54] * MichiBot accepts the dream of pair 'a dice and adds it to her inventory
L337[21:11:26] <Liizzii> bah, wanna fast forward to next wednesday so i can watch the next episode of eminence in shadow
L338[21:11:42] <Izzy> same but nov 10
L339[21:11:54] <Izzy> for the next season of For All Mankind
L340[21:14:08] <Kristo​pher38> Izzy: I watched first few episodes and disliked the focus on politics and very infantile way of some decisionmaking presented there
L341[21:14:58] <Kristo​pher38> I think I lost it at "the president said that the ||first american woman on the moon must be pretty||"
L342[21:15:04] <Izzy> I dislike the amount of Interpersonal Bullshit that goes on
L343[21:15:12] <Izzy> but there's only so much hard sci-fi out there
L344[21:15:51] <Kristo​pher38> do you recommend any
L345[21:17:27] <Izzy> The Expanse is excellent, especially the books. Moonlight Mile is neat, though hard to find a copy of. Planetes is an easy recommend. Avatar (blue people) is surprisingly hard sci-fi, but mostly in the worldbuilding. Stowaway was neat too.
L346[21:18:44] <Kristo​pher38> will check those out
L347[21:19:55] <Izzy> Tsuki to Laika to Nosferatu gets an honorable mention too; I'm not sure I'd say it's good, but it's charming and definitely hard sci-fi.
L348[21:21:53] <Kristo​pher38> careful, you'll wake up sam
L349[21:23:22] <Izzy> oh! Rocket Girls, too
L350[21:24:02] <Liizzii> do the rocket girls kiss?
L351[21:24:13] <Izzy> no, as they are related
L352[21:24:20] <Liizzii> aww
L353[21:25:59] <Amanda> Now I'm reminded of that one magical girl anime where the secret to magic is Yuri bait
L354[21:26:11] <Amanda> ( kisses on the cheek / forehead )
L355[21:26:38] <Amanda> (though, sending that, a lot of MG anime is Yuri bait)
L356[21:26:51] <Izzy> aight Gandi is gonna kick me out, who should I pay to host my email?
L357[21:28:21] <Liizzii> I'd like to say i'm a good email host. though my email setup isn't in a state of being able to have not-me using it right now
L358[21:29:08] <Mim​iru> Depending on what you need I might be able to help
L359[21:29:42] <Amanda> If you give me scritchies I'll secretly just host your email with Google
L360[21:29:50] <Liizzii> ah yes
L361[21:29:56] <Liizzii> Izzy hosting their email with google
L362[21:30:06] <Liizzii> they'll love that :D
L363[21:30:27] <Mim​iru> lol
L364[21:31:25] <Amanda> I made this state of the art web ui, it's available at Gmail
L365[21:31:25] <Amanda> Com!
L366[21:31:44] <S​3> I've been hosting my email from ramnode for about 5 years or so now
L367[21:31:51] <S​3> Before that it was ovj
L368[21:32:00] <S​3> Ovh*
L369[21:32:15] <Liizzii> been self-hosting mine for some time, at least the last 5 years
L370[21:32:40] <Mim​iru> I have a SMTP relay on OVH, since my ISP blocks port 25 *grumble*
L371[21:33:03] <Mim​iru> But email is hosted in a machine I can go down stairs and slap if it gets too bad. lol
L372[21:33:09] <Izzy> I only have two mailboxes but I kinda just don't want to think about it
L373[21:33:16] <Izzy> it's a pain in the ass
L374[21:33:26] <Liizzii> i don't have to think about mine too much
L375[21:33:38] <Forec​aster> I let my registrar host my email that I barely use
L376[21:33:49] <Liizzii> other than monitoring for the occasional spam bot and just drop it's IP in the raw table
L377[21:33:52] <Forec​aster> it's very convenient because I don't have to think about it at all
L378[21:33:59] <Izzy> Forecaster: that's what I was doing
L379[21:34:02] <Liizzii> though after blocking most of china, email spam is less
L380[21:34:04] <Forec​aster> I quickly gave up on self-hosting because it was a huge pain
L381[21:34:05] <Izzy> but now gandi wants me to pay separately
L382[21:34:19] <S​3> I'm working towards using a dynamic mail alias table, so that I can match a prefix or something when I send emails s authenticated, allowing me to make up email addresses for signing up to things that alias back to the real account
L383[21:34:24] <Mim​iru> I do hate email hosting... lol
L384[21:34:41] <Izzy> they want like $70/year to store 100K of data or so
L385[21:34:49] <Mim​iru> I have a catchall address that just forwards back to my main account lol
L386[21:35:04] <Forec​aster> I'm paying for domains + mail hosting
L387[21:35:07] <Liizzii> hmm, actually i lie
L388[21:35:18] <Liizzii> it's really easy for me to add new domains and such to my postfix config
L389[21:35:19] <Mim​iru> So if you send to fuckyou@pc-logix.com it is forwarded to me (and then again to my gmail lol)
L390[21:35:37] <Forec​aster> I think I get like 5 actual mailboxes plus like 100 alias adresses
L391[21:35:38] <S​3> That way if I want to stop subscribing to a service that doesn't let me unsubscribe (fuck you new York times) then I can just remove the alias my smtpd made when I signed up.
L392[21:35:42] <Izzy> which registrar are you with Forecaster?
L393[21:35:58] <Forec​aster> Loopia, it's a europeian one
L394[21:36:22] <S​3> I use name cheap but that is p probably us based I never checked
L395[21:36:42] <Forec​aster> actually it's unlimited aliases
L396[21:36:59] <Forec​aster> 25 GB of email space
L397[21:37:24] <S​3> That's a ton
L398[21:37:32] <Izzy> impressively, their separate email costs more than gandi's
L399[21:38:26] <S​3> I block html and stuff like that so they biggest space abusers for me are attachments
L400[21:38:43] <Liizzii> Izzy, I can offer you basic "it just works" email + imap access, no storage quotas and Proxmox Mail Gateway doing anti-spam for $0 (cause i'm already hosting it for myself, so adding another user/domain wont hurt, especially with how much fail2ban spams my sysadmin address)
L401[21:39:18] <Izzy> Liizzii: if I don't find a reasonably priced alternative I might take you up on that
L402[21:39:19] <S​3> The spam filter just filters the html tags out on receive so I don't have to do it from the client
L403[21:39:20] <Michiyo> I can offer the same, without PMG for anti-spam
L404[21:39:44] <Izzy> (trying to avoid mixing """business""" and friends if I can though, y'know?)
L405[21:40:16] <Izzy> after all, I need this mailbox to know when people have discarded my job applications
L406[21:40:27] <Forec​aster> I pay about $67 a year I think
L407[21:41:57] <Forec​aster> which I consider reasonable with how well it works and their simple but decent web interface both for managing stuff and their email client
L408[21:43:11] <Liizzii> I can also offer webmail. though i should probably update it and you'd probably be better with a normal desktop client anyway
L409[21:43:32] <Izzy> I just use thunderbird \o/
L410[21:43:37] <Liizzii> same
L411[21:43:48] <Liizzii> i just have the webmail for when i'm not with my laptop
L412[21:43:53] <Izzy> speaking of, the interface went weird for like two days
L413[21:44:05] <Izzy> all the tab titles were black and unreadable on the dark grey background
L414[21:44:08] <Forec​aster> I mainly use a phone app
L415[21:44:12] <Izzy> but now they're back to respecting my theme colours
L416[21:44:23] * Amanda replaces all of Liizzii's emails with pictures of toe beans
L417[21:44:28] <Izzy> oh, nope, never mind, it's broken when focused
L418[21:44:35] <Liizzii> or the internet is being extra spicy and more people are trying to break into my ssh daemons and fail2ban is banning them
L419[21:44:59] <Forec​aster> I used to use thunderbird many years ago, but I started hating it when it kept breaking my plugins constantly during a period and just stopped using it
L420[21:45:27] <Liizzii> Amanda, that's at least 33k beans just going by the unread emails from fail2ban alone
L421[21:46:11] <Liizzii> that reminds me, i'ma go turn off port forwarding to ssh on my home server cause i don't need it
L422[21:46:39] <Forec​aster> but what if you suddenly do?!
L423[21:46:53] <Forec​aster> I always have it on, but I use a non-standard port for it
L424[21:47:02] <Liizzii> i can just go in via my dedi
L425[21:47:17] <Forec​aster> but that's cheating
L426[21:51:30] <Forec​aster> all my servers are home servers
L427[21:51:57] <Michiyo> I have a $7/m OVH VPS, but everything else is racked downstairs.
L428[21:53:01] <Forec​aster> $7 per minute sounds expensive
L429[21:53:12] <Michiyo> Eh, you do what you can ya know.
L430[21:53:36] <Forec​aster> but if it's $7 per mile thats reasonable
L431[21:53:58] <Izzy> $7 per mole
L432[21:54:56] <Forec​aster> counting the atoms in a server to calculate the price sounds hard
L433[22:25:10] <S​3> I think I pay $3/mo for my VPS that runs my email and DNS
L434[22:34:24] <Forec​aster> I have no VPS...es...
L435[22:37:27] <ThePiGuy24> VPS when RPC (real public client) walks in
L436[22:50:09] <Comput​erCoco> 2 Questions
L437[22:50:09] <Comput​erCoco> 1) https://www.curseforge.com/minecraft/mc-mods/scalable-cats-force This mod seems to add scala from 1.17 to 1.20, is that correct?
L438[22:50:09] <Comput​erCoco> 2) https://github.com/GTNewHorizons/OpenComputers What is this? Is this a try at OC 1.19? I can't tell what version of MC its for. I tried loading it in forge 1.19.2 and my computer basically froze on the "Joining world" screen, dispite making it to main menu... Hmmm
L439[22:58:59] <Comput​erCoco> Well I got the game to load, turns out its not a 1.19.2 mod, then did the thing I should've done first which is check the mcinfo file, which says its for a forge version thats for minecraft 1.7
L440[22:59:00] <Comput​erCoco> So it doesn't seem its for a newer version
L441[23:02:18] <Mim​iru> It's a fork that someone has made to update the mod, and it's not done... just like every other fork folks have made to try to update to newer MC versions.
L442[23:02:43] <Comput​erCoco> Yea fair
L443[23:03:12] <Comput​erCoco> I tried myself once xD
L444[23:08:41] <Izzy> GTNH suggests 1.7.10
L445[23:11:00] <Izzy> can I get a "fuck neural networks"? "Tensor Processing Units" have made it very difficult to look up info on the DEC Text Processing Utility

L447[23:23:58] <Mim​iru> Wait... I can't use my powered off computer for this? shit.

L449[23:30:13] <Izzy> OC wins again (you can copy EEPROMs without power)
L450[23:38:47] <Liizzii> hmm, so openssh sends the `OpenSSH <version>` string when it connects, which you could theoretically use to have some form of TCP loadbalancer/reverse proxy to allow multiple protocols (e.g. SSH, HTTPS, probably some others). I wonder if you could get OpenSSH to send the hostname it wants to connect to in with or before the version string and then
L451[23:38:47] <Liizzii> have said loadbalancer/reverse proxy use that to direct the ssh session to some other destination than a theoretical default.
L452[23:38:55] <Liizzii> could be interesting to do
L453[23:39:15] <Liizzii> though you could also just as easily use jump hosts i guess...
L454[23:40:30] <Liizzii> was thinking that it could be used for stuff like gitlab/gitea, to be able to have multiple ssh servers "listening" on port 22 of some public ip
L455[23:40:53] <Liizzii> though the setup of getting that to work in the first place could just be spent on using a jump host
L456[23:40:55] <Izzy> there's an nginx module to do ssh on HTTPS ports
L457[23:41:06] <Izzy> and there's software to direct your ssh connection based on username
L458[23:41:39] <Amanda> And with some cursed zenscript you can even transcribe it from a written book into the eeproms
L459[23:41:42] <Liizzii> oh? i thought the ssh protocol set up the secure connection before it would send any credential data
L460[23:43:58] <Liizzii> hmm, i wonder if any of the bots that try to break into ssh stuff would also try ssh on https ports... might be an interesting way to have ssh "listen" on a well-known (and loosely blocked) port and not have it open on the port bots commonly attacked
L461[23:49:05] * Liizzii makes a note to research that later, for now it's bed time
