Looking at the pictures it looks like the fiber itself might be inside of that spiral metal conduit in the middle and the outside is just abrasion protection. There are way too many strands for that outside bit to be the fiber. It's obviously bad that the outside plastic disintegrated, but it looks like the buried cables might be fine.
I have a similar problem on my car where the 12v wiring is disintegrating like this because the manufacturer tried to switch to a more environmentally friendly wiring. Now the wire jackets turn to dust at the slightest touch or if they vibrate too much. I'm forever tracking down intermittent shorts in the wiring harness.
The metal coil will hold the actual fibre itself, yes - after a few more layers of protection. This is what is usually called “armoured” cable and is suitable for suspension and direct in ground. Dunno why he’s using it indoors.
Honestly, this writeup is… weird? Dude doesn’t know you can terminate fibre at home with like $50 of gear?
I had the fucking fox attack a freshly laid 500 meter line, literally the day before I was going to stuff it in conduit and bury it. Didn’t just break the fibre, she (I know this fox, well) chomped it into pieces, hauled on the exposed Kevlar, generally had a party.
Did I despair? Did I launch a baby complete with bathwater into the sun?
No. I bought a cleaver, some alcohol wipes, some stripping pliers and a whole bunch of mechanical terminators.
Needn’t have worried. Repaired it, outdoors, first attempt, in the rain, and have since buried it - no problems five months on.
Hey actually I didn't know! It's my very first time dealing with fibre networking so I just maxed out the supposed durability specs. I figured I'd rather go overkill than regret not having done so. Ironic I know.
Unfortunately I can't easily dig the cable out and bury it again in this case. I'll have to figure out how to pull a new cable using the existing cable through the PVC conduits as the cable shares a larger conduit with multiple other fibre and Ethernet cables. The whole project was orchestrated remotely in a different timezone with me giving the electricians instructions over WhatsApp photos and audio recordings, so that limited what I could realistically control onsite back then. Often the contractors would proceed with a do first ask questions later approach while I was still asleep. The networking project was holding up the entire home renovation so everything was learnt and planned in a short amount of time.
AFAIK fibre splicing and terminating tools are very expensive. Do point me in the right direction for the $50 tools and I could go get some and DIY.
> AFAIK fibre splicing and terminating tools are very expensive.
They're more like $600 expensive than $6000 expensive these days. For very low budget, you could go with a mechanical (aerobic) splice; it's more loss, less robust and takes up more space, but doesn't require a fusion splicer.
Back in my day the local telephone company used waxed lacing cable for that sort of thing[1]. These days it seems that polypropylene string is popular (search on "conduit pull string").
You basically want something that is slippery and will tend to not get stuck. I have used Dacron fishing line, but that is mostly because I had a bunch of it laying around.
I wanted to reach you regarding your comment here: https://news.ycombinator.com/item?id=44547866 Would you be willing to maybe elaborate on the problems caused - I've planned to adopt Miro Sameks for an application?
DM me via my about me, if interested. Would be very thankful.
Yes, the whole thing is built like bike brake cables, with a spirally metal support core, the goodies up the inside, and then a nylon braid and PVC jacket over the top.
I have issues with the PVC-jacketed cables under the bonnet of my nearly-30-year-old Landrover, where the plasticiser has been baked out of the insulation and they've gone brittle. Worst affected are the wires to the fuel injectors and the lambda sensors, presumably because the former are at the top of the engine and get reflected heat off the bonnet, and the latter because they're near the literally red-hot exhaust downpipes.
That's okay for an old vehicle that you'd expect to repair, though.
I've seen the same problem in three-year-old Toyotas, and that is Just Not On.
BMW and Toyota have famously used bio-derived insulation reported to be like catnip for rodents.
The bio-oil plasticizers also migrate out more quickly in thermal cycling than the old dead dinosaurs approach. Hilariously, when I asked my mechanic about getting an M5, he laughed and explained that the radiator components are known to turn brittle and crack after 5-6 years because of this.
(I don't envy automotive folks. The stuff they have to deal with is next level.)
Last time I had to call AAA to jump my car, the guy opened the hood very carefully and told me he’d had three rats jump out of engines at him that day, presumably because of the “soy wires.”
Nothing can beat the 600 Mercedes for cachet though. Look at the list of owners: Idi Amin, Ceauşescu, Saddam Hussein, F.W.de Klerk, Papa Doc, Mugabe, Brezhnev, Tito, Mao, Kim Il-Sung, Ferdinand Marcos, Deng Xiaoping, Mobutu, Jean-Bédel Bokassa, Mubarak, Berlusconi, Pablo Escobar, Jeremy Clarkson, nothing will ever come close to that.
The Wikipedia article made it sound like more of a "land cruise". The bus stopped at some tourist and shopping destinations along the way and the description make it sound more like a cabin cruiser than your typical bus. I can see the appeal for people who want to travel and don't have a lot of money. Definitely easier than hitchhiking across the continent.
I agree that it stretches credulity but one scenario is that they were promised the Venezuelan military would stand down and let the US conduct its operation with minimal resistance. If that was not the case then the minimal troops for the beachhead may have decided that the token landing for PR purposes was not necessary and bugged out.
One of the strangest things about the entire operation is how the US left absolutely nobody behind to administer the country. Not even a consultant. The Venezuelan VP is now in charge and the government is largely intact. It's hard to see how this affects any meaningful change in the country. I did find it amusing that the opposition leader released a statement with her lips firmly planted on Trumps ass and even talked about "sharing" the Nobel Peace Prize just to see if he's enough of an idiot that such obvious flattery would work.
> The Venezuelan VP is now in charge and the government is largely intact. It's hard to see how this affects any meaningful change in the country.
It's a threat - "Do as we say or you're next." Which the US was pretty public and explicit about. They don't need anyone on site for that. It's not like they actually care what happens beyond the resources use.
Prolog is great because when it works it feels like magic. You give it some pragmas and it tells you the answer. The downside is when it doesn't work it also feels like magic. It's not easy to reason about the amount of work it needs to do. If your Prolog program is taking a long time to run it is hard to figure out if it is going to take 2 hours or 4,000 millennia.
Generally the larger the codebase the harder it is to secure. I am less worried about security vulnerabilities on small tightly focused apps than I am on gigantic monstrosities with hundreds of different attack surfaces.
> Transcripts: Multiple dollars per pages. Want that expedited? Multiply that amount by four. Don't know the court date? Can't get your transcript. Clerks put in the wrong date? Tough luck. Payment for those transcripts? Over Zelle because the court reporters themselves are contractors and get paid independently.
Is this because a person has to literally transcribe the stenographer's notes into plain English? Is it expensive because it is labor intensive?
Yes and yes. I'm sure there's historical or possibly ethical reasons for it being this way, but I don't understand why it's not the clerk of court's job. Something to figure out!
Over here in Sweden they justify the fees for printed cases by the paper cost. Cheaper than the number you mentioned but still quite costly if you want all nontrivial verdicts. And quite silly when they deliver pdfs..
Then every single case needs to have all PII redacted before it is made searchable, but that is a different story.
Before Elon bought it out it was mostly possible to contain the hate with a carefully curated feed. Afterward the first reply on any post is some blue check Nazi and/or bot. Elon amplifying the racism by reposting white supremacist content, no matter how fabricated/false/misleading, is quite a signal to send to the rest of the userbase.
he's rigged the algorithm to boost content he interacts with, unbanned and stopped moderating nazi content and then boosted those accounts by interacting with them.
