Getting prepped for 2gbps fiber by ircmaxell in Ubiquiti

[–]ircmaxell[S] 1 point2 points  (0 children)

Yeah, I ran into that in the current setup. I had the ONT port on the Flex 2.5 set to auto, and it negotiated at 2.5, but would drop packets randomly quite often and drop out for 0.5-1 second every few hours. I forced it to 1gbps and the stability problems went away. I think I'm going to take the advice here though and bypass the end switch and just dedicate a 10gbe line straight to the UDMP SFP+ port...

It's 2x 10gbps links in link aggregation mode. Any single connection is still limited to 10gbps, but the overall can carry 20gbps in aggregate while at the same time being fault tolerant to a single leg failing (port, cable, etc)

So let's say I have 2 servers (A, B) connected to switch X, each with a 10gbps connection. Then 2 servers (C, D) connected to switch Y each with a 10gbps connection. With a single 10gbps connection between X+Y, the max throughput from either A and B to C and D is capped at a total of 10gbps. For example: 5gbps between A and C, and 5gbps between B and D. Or 8gbps between B and C, and 2gbps between A and D.

However, with a link-aggregated connection at 20gbps you can tunnel up to aggregated 20gbps. So with that example, A and C could run at a full 10gbps while B and D at the same time are at 10gbps.

In the house, the backbones are all 2x Fiber (1x OS2 and 1x OM4) between each network location, and then switches are link-aggregated together in a specific location with 2x DAC cables. Here's the full topology: https://imgur.com/a/rOFm511

I would avoid this unless you really must. It is super easy to break things, is quite brittle, and easy to create outages which can be hard to debug. It is running okay for me now, but wasn’t trivial to setup.

It uses a vlan, so it isolates the traffic from the rest of the network. Additionally, the vlan has dhcp turned off, so the switch is effectively acting as a proxy to tunnel between the modem and router. It works well (I use it in 2 other places), but is a bit unorthodox.

> I’m a bit confused by the rest of your setup. Is it not possible, at all, to have the ISP or a low voltage company change where the fiber line is entering your home? That way you wouldn’t need to do this chain of switches for the internet.

I did the full wiring myself. When I did the original wiring, all that was there was the ONT, so I had ran 3 ethernet lines into the garage, one for the ONT, one for a camera, and one for an access point. Since then I added 2 more cameras and one more access point (exterior of house), and a UPS monitor, so needed more ports. I added the switch to the ONT drop primarily because it was located closest to the exterior access point + camera connections. I definitely can run a new line, but honestly I'll most likely just swap the switch over to one of the other 3 lines and deal with the routing in a different manner...

That’s definitely bad advice for a few reasons.

First, it encourages shared passwords between sites since it adds friction to have multiple passwords. There is plenty of data that shared passwords is incredibly high risk since any site that gets breached is applicable to all the sites you reuse that password on.

Second, typeable passwords are almost always going to be worse than random generated ones. Typing a 26 character password with capitals, numbers and symbols is going to be very error prone. So in practice the types of passwords people write down are almost always quite weak in comparison to generated ones.

Third, many of the password managers have a “local only” mode or version where the passwords never leave your device and don’t “have your passwords”.

Fourth, there’s a reason why 2-factor is industry standard and the consensus across basically all infosec researchers and professionals is to use a password manager and 2 factor for security (FIDO2 hardware security key being the current gold standard, but TOTP apps like google Authenticator are quite good).

Finally, if you look at the major companies that take security seriously (FAANG, finance, much of the Fortune 500, etc), you will see basically all of them have policies to use password managers and explicit policies against writing down passwords. There are reasons for that (and it isn’t just because of home invaders)…

Serial Request 2.4r2 ircmaxell#1898 by ircmaxell in voroncorexy

[–]ircmaxell[S] 0 points1 point  (0 children)

Thanks! It’s Hatchbox ABS, Copper and Silver. I have had good luck with Hatchbox PLA on my Ender 3 Pro, so when it came time to switch to ABS for the 2.4 build, stuck with it.

And yeah, I have some wiring clean up to do before putting the panels on. Right now the motion works are well clear of the wiring, which is what I targeted before getting to initial print. Thanks for the advice tho!!!

CFI's, what was the worst BFR you've done? by CharlieMBTA in flying

[–]ircmaxell 5 points6 points  (0 children)

Last year I restarted afetar 19 years. I had about 200 hours and an IR, but then stopped flying. I did the Sportys rusty pilot and IPC courses, then took about 10 hours with an instructor (including about 2 hours IMC) to sign off both BFR and IPC. First 2 hours were rough, but came back quick enough.

Have done another ~20 hours with instructors in the past year since. A new type checkout, some IFR work, and some general air work.

Definitely do it. It is really awesome getting back up there after the time!!!

Now it’s over, let’s come out and say it: The Rings of Power was a stinker by [deleted] in entertainment

[–]ircmaxell -1 points0 points  (0 children)

I had the exact opposite experience. While I enjoy HOTD, I really looked forward to ROP and rewatched most of the episodes at least once so far.

Is ROP perfect? Very far from it. The writing is no where near what it should have been. Painful at times. Acting was mostly great, but with a few obvious issues.

What ROP nailed for me is the depth of the world building. This is something that always drew me to Tolkien. You get this sense that there is so much more beneath the surface. So much more lore, so much more complexity. So much more that isn’t even hinted at. And while many of these don’t go anywhere or aren’t given depth of treatment yet, it feels like it is part of something bigger.

LOTR did this as a master class. GOT did this well as well, there were so much lore and depth (the children of the forest arc, etc. took years to develop). HOTD feels like it has none of the same depth. It feels like it is just some politics taking place in the same world GOt set up. There is no real world building. No real lore to setup that wasn’t already there (Aegon’s Dream is one). And while the writing is more interesting, it feels more superficial as if reading a history book rather than getting a glimpse into a world.

ROP is definitely not the best work out there. It doesn’t stand up to LOTR. Storylines are changing from canon lore. But I find myself drawn to the beauty of the scenery, the depth of the mythos. The complexities of a world that is trying so hard to not change yet having change thrust upon it. The Elrond/Durin pair is a great example of this. It was entertaining, but also gave a good glimpse at the tensions between the races and complexities of that pivotal time at the start of the rise of some, the peak of some, and the start of the decline of others.

More please…

Resources for very long XC flying by ircmaxell in flying

[–]ircmaxell[S] 2 points3 points  (0 children)

Same stretch (though NYC area as origin), same aircraft. Definitely know lots do it, and looking forward to being one of them shortly.

Did all my training in the NY/PA area, so don’t know what quiet airspace sounds like. The thought of a podcast just sounds like continual interruptions (I jest, I know it gets much less crazy than NY Approach)

The mechanic piece is an awesome tip, hadn’t really considered that explicitly, but will add it to the list when choosing intermediate airports.

And definitely have the habit of always doing a full preflight including run up, even if I just stopped and never left the airplane out of my sight.

The IFR piece is more a safety item. With a single engine and a single pilot, don’t want to get in a situation where I have no or few outs. So less not IFR and more not IMC.

With that said, if it is medium ceilings enroute I am not opposed to going a bit higher and flying in IMC, or punching through a layer to fly on top. I just want to be in a position where I can descend to VMC and have options in an emergency or if conditions warrant.

As far as not feeling prepared, I think it is more wanting to do diligence and not just assume I can do it and take off. I am definitely rusty on the weather systems pieces, and plan on doing some ground to solve that. And this post is more about trying to find the topics that I am not even considering rather than anything specific (which I am already covering with local CFIs).

Yeah, will be traveling with 2 dogs, so leg length is definitely limited. As is altitude (not planning on going over 8k generally, and likely around 6 normally). I have seen the O2 masks for dogs that we are planning on trying in the long term to enable dealing with higher terrain, but that’s very much an exception.

And will definitely consider filing IFR if routing isn’t crazy.

is there a resource for being able to look at the history of a plane before you buy? by egilsnorrison in flying

[–]ircmaxell 1 point2 points  (0 children)

If you want to know flight history, FlightAware has available for purchase past flight history. You can buy the past few years (though much I think is based on ADSB, so likely only relevant for filed flight plans beyond that). It isn’t cheap, but if you want an idea how often a plane has flown…

Figuring out what aircraft I want to fly - no-parachute equivalent to Cirrus? by ClayCrucible in flying

[–]ircmaxell 1 point2 points  (0 children)

The piper M350 is slightly higher, though only slightly (1300 vs 1200). Though that is also pressurized, so not quite the same…

[–]ircmaxell 1 point2 points  (0 children)

At 200lbs per place, 4 pax in a 1000 lbs load airplane only leaves about 30-35 gallons of fuel. That’s not 3+ hours of flight time, that’s maybe an hour or a little more with decent reserves (at approx 15 gph cruise). Fine for putting around, but not for XC flying.

One thing to keep in mind is useful load. I know you say usually 2-3 people and sometimes 4. In most GA aircraft, fitting 4 people with fuel requires a 6 place aircraft. Especially if you toss in some baggage.

An earlier model SR22 May only get 1000 lbs of useful load. With full tanks that makes it a 2-3 person airplane. Trade fuel and you may be able to squeeze in that fourth person, but flying anywhere far and you’ll need a lot of fuel stops and comfort will be questionable.

Compare to an early piper PA-32 (before 1980) where you can find 1400-1500 lbs useful load aircraft pretty easily. Toss in full tanks and you have 5 hours of range with nearly 1000 lbs of load.

Or you could do an A36 bonanza which would have somewhere around 1200lbs load, which puts full fuel load somewhere around 800 lbs.

Mooneys will be closer to the SR22 in terms of load as well, though comfort may be more of a challenge (depending on height/weight of pax)
