Science research on the one hand is cursed to follow the money.
angrystego@lemmy.world 3 weeks ago
My own experience leaves me a bit more optimistic, although I do see some cursed bits.
The presence of money in research depends greatly on the field and the ability of the scientists to make their research sound sexy. You can mask a lot of wierd niche basic research topics with sexy applied research talk.
Also, there’s still a lot of science research without much money, being sustained by sheer enthusiasm.

thankfully i’m not a scientist, but if the people much smarter than me, and collective consensus say one thing, i’m likely to agree broadly with that sentiment. If not, same goes but in reverse.
Now if i were doing science on the other hand…

Research is based on the so-called scientific method (therefore science) and that is something you can’t proof, just belief in. But it’s the best we have with extraordinary amount of evidence to back it up.

There was this guy who spent his whole life in rural Arizona. All evidence indicated that the world is made of sand.
Never discount errors of perspective.
If you consider something that all scientists do then you might see a vast shared error.

using the scientific method to demonstrate that the scientific method is the most effective method of science is definitely one of the moments of all time, for science.

Not a scientist. I have a litany of complex topics that I just can’t really talk to anyone about. I’m a big computer networking nerd, and once upon a time, when I didn’t know what I didn’t know, I was curious what computer networking really entailed… It seemed dead simple, you connect things to a switch, connect that switch to the internet router, not much more.
Then I learned about VLANs, which are cool but it seemed like unnecessary complexity. Then I learned about Routing and L3 switching, and routing protocols and… Holy shit, how deep is this?
Now-a-days, I want to have conversations about the merits of one routing protocol over another in various contexts, and see/build a spine and leaf network infrastructure that’s nearly infinitely scalable.
I want to explore the nuance of IP unnumbered routing. I can’t find anyone who will chat about it on a level that’s close to my understanding, either someone knows way more than I do, or they know way less.
IP unnumbered routing is a way of connecting devices without setting an IP on the interface that is being routed to/from. The other end uses the routing protocol on top of layer 2, and while the two might have a router ID, often in the form of an IP address, the interface that is connecting the two has no IP. It’s basically advanced point to point protocol (PPP) that breaks away from traditional TCP/IP routing in ways that people who have never used anything besides TCP/IP can’t really comprehend. The two “IP addresses” (actually router IDs) in play can have nothing in common. Traditional TCP/IP requires that two IPs share a subnet. In routing, this is typically a /30 for IPv4, and the two IPs are adjacent to eachother, eg, 10.254.123.1 and 10.254.123.2 IP unnumbered can have 10.254.123.2 talking directly with 172.30.88.207, with no layer 3 interfaces in-between.
It’s really fascinating and interesting and I’ve been trying to find a good model or guide to help me learn this better, but I keep ending up at dead ends, and I have nobody to talk to about it.
kantor@lemmy.ml 3 weeks ago
Did my fair share of networking back in the day, but never heard of IP unnumbered. I was curious about the same idea back in the day and it is possible, but I haven’t much seen anyone doing it for realsies. If you have any good longreads/vids on the topic, it’d be much appreciated.
MystikIncarnate@lemmy.ca 3 weeks ago
I’ll look at my resources and see what I can dig up. No promises, but the concepts are simple as long as you can separate yourself from the TCP/IP restrictions on two things needing to be in a subnet, and the idea that NAT is something that needs to happen.
Honestly, I’ve seen so many people get hung up on the fact that NAT isn’t universal, or necessary.

bro i just want screensharing that isn’t using the hell that is webrtc.
How hard is it to send video packets over IP, it can’t be that difficult. Half the job is already done, and i can’t imagine building a reliable networking protocol, even if you had to do it from scratch would be particularly hard.
everything is webrtc, it always has been.
MystikIncarnate@lemmy.ca 3 weeks ago
See, I only recently came into awareness that web RTC was a thing. I have a lot of learning to do on how it even works as a protocol.
I’m sure it runs on top of IP, so I think web RTC meets your curriculum here. Regardless of that, I think I know what you mean, and if I knew enough about the protocol, I might even agree.
I need to brush up on the new protocols that are getting to be very common. I’m almost entirely up to date on the 802.11 specs, but there’s so much to keep track of… Yikes.

I need some help with networking and eventually getting an organisation website online; if you want to geek out a bit, please send me a dm. :)
MystikIncarnate@lemmy.ca 3 weeks ago
Bringing a website online sounds a lot more like development stuff.
Networking is all about how to get data from one place to another that is reasonable, manageable and scalable. Knowing what devices are increasing latency and when you should adjust the settings to route around a high latency (and/or high loss) link to enhance performance and reliability. Visibility into network flows in real time and monitoring for every link and port that’s connected to a device, switch, router, or computer.
Web hosting is system admin and development.
What networking concerns do you have with this website?
Strykker@programming.dev 3 weeks ago
Sounds like you should look at IS-IS protocol if you haven’t as that’s very close to the ip unnumbered routing you were talking about. Though isis is usually deployed with its on the interface of each device, it doesn’t have to be AFAIK.
MystikIncarnate@lemmy.ca 2 weeks ago
I recently saw a post about Babel getting up unnumbered, and AFAIK OSPF and IS-IS have both had it for a while.
Implementations are spotty on support of unnumbered, there’s still quite a few, mostly older OSPF devices that require an IP interface to communicate with another device for OSPF.
I’ve been trying to get a functional IP unnumbered lab up and running but there’s a lot of unknown-unknowns for me still… At least when it comes to implementation.
Of course, a router ID is still a requirement, foreign devices still need a way to uniquely identify what device they’re talking to.
Maybe I should try the lab with IS-IS, but I know less about IS-IS than I do about OSPF at the moment. I should change that.
iknowitwheniseeit@lemmynsfw.com 3 weeks ago
I’m not sure that I understand the benefit of “unnumbered” routing. It sounds like there are numbers (well, “identifiers”), just not IP addresses.
It’s hard to know without more context, but you can use things like IPv6 multicast to manage reachability. This will let you set arbitrary sets of endpoints that talk to each other, and you can still us IP-based tools to debug connectivity, measure performance, and so on.
MystikIncarnate@lemmy.ca 2 weeks ago
The benefits are pretty simple but have broader implications than what would be apparent on the surface.
Let me lay down a little ground work first. Traditionally with routing protocols you need to implement a /30 between interfaces on the connected devices before routing will come up. Usually that requires the use of IPAM, and a lot of record keeping to ensure nothing overlaps.
So let’s take the example of a relatively simple spine and leaf topology. A leaf switch dies, or otherwise needs replacing. You set up the new leaf with a template, which contains pretty much all the routing commands you’ll need, and all of your overlay transport, VLAN definitions, and whatever. After that, you need to program the uplink interfaces to the spine(s) - hopefully at least two - in order to get it online.
If you’re doing a replacement because a switch died, looking up the interface IP assignments for the leaf is going to take a lot of time, nevermind programming the addresses, and all the possible fat finger typos that could happen, just to get the switch communicating in your underlay (and to your management systems).
In small networks, not a big deal, you’re dealing with maybe a dozen such devices at most, but in large scale provider, datacenter, or hyperscale networks with literally hundreds of racks, each with a top-of-rack leaf switch, good luck.
Enter IP unnumbered. Same situation. You can pre-prepare any standby switches with unique loopback IPs in the routing system, and mark them as used in the IPAM for a standby device. A failure happens, you grab a standby switch and head to the rack. Next you yank all of the port connections out and plug them into the standby switch and power it up ASAP. Without touching the config at all, it grabs the routing and comes online, and the NOC can simply apply the port config for that rack on that switch from their management console.
This can easily cut repair time in half or better.
Any switch can be moved anywhere in the enjoyment and it will come online right away.

There’s one thing they aren’t screaming about: how free will is a myth. It’s a topic that gets shot down a lot.
Gerbylynn@sh.itjust.works 3 weeks ago
That’s barely an info dump on the subject. Observe - Free will is a complicated subject. If there is a divine creation (or simulation or whatever) then then what started the universe was a seed - or rather a set series of circumstances that started everything. Then everything built on that leading to me writing and you reading this. Free will is a choice - a decision to choose where your decisions come from. Are you truly in control or do you just choose the best possible outcome based on past relevant experiences? Obviously you will live with the consequences, no one’s saying you wouldn’t 👀 Regardless, we’re all built on consequences of our past self which’ll in turn become your new past self. And from there it’ll continue till death. Obviously death itself is complicated and you’ll eventually face it. And what happens afterwards is another conversation. But until then you’ll make the most of it. Every damn day.

I can only hope the changing mating habit is that they’ve all stopped mating. I hate those damn bugs.
They’re invasive where I live, and it seems like they don’t really have predators. And they’re so damn loud when they fly around inside your house. And they smell awful if you startle them or squish them. Only thing I can do is catch them in a cup and flush them down the toilet.

I browse Windy but don’t rely on any of those 4 weather forecasting models: I take the median of predicted temperatures and rainfalls instead. Also, I predict rain only if the median exceeds 1mm, and if it’s below that threshold but at least 3 models predict (some) rainfall I predict drizzle. Which is the same approach I had at my previous job, using data of doubtful quality to adjust Holt-Winters and Box-Jenkins models in order to forecast drug sales for Big Pharma.
Kaggle by the way began to demand users engaged on modelling competitions to make PDFs explaining their methodologies after learning some cheaters would just combine results from other competitors.
P.S. - Don’t average results from different models unless you are really, really sure of what you’re doing. Many times the models take turns on which one will output garbage, and you don’t want garbage contaminating your average. By switching to median you avoid the crap they sometimes spit altogether - not to mention it’s so simple you don’t even need to write numbers on paper or use a pocket calculator.

In vulcano seismology there is this fun little thing called a tremor and its really annoying but also really mysterious as no one knows where it is coming from or what cases it. I’ve had multiple people try to explain it or I was listenin to talks about it and I have yet to hear solidly overlapping theories. Also not only does the signal look different at every single opportunity (aka every vulcano) that you to look at it, it also hides within a frequency range that is mostly overlapped with random background signal. So to look at it you need to do analzye your seismometers for a directional eigenvalue (not sure if its the correct word or even the only what its just what I’m doing. I’m normally German speaking but what we do is look at the seismometers and whether or nor all or most of the signals are comming from the same direction) so that you can even detect it, meanin just to look at it you already need some statistics.
Not really sure where I’m going with this I just find this concept really really and I’m just once again baffled that we simply do not know about things in science.
